SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

This prospectus supplement, the accompanying prospectus, and the documents incorporated by reference herein and therein contain certain "forward-looking statements" within the meaning of such term in the Private Securities Litigation Reform Act of 1995. We and our representatives may, from time to time, make written or oral statements that are "forward-looking" and provide information other than historical information. These statements involve known and unknown risks, uncertainties and other factors that may cause actual results to be materially different from any results, levels of activity, performance or achievements expressed or implied by any forward-looking statement. These factors include, among other things, the factors listed below.

Forward-looking statements, which may be based upon beliefs, expectations and assumptions of our management and on information currently available to management, are generally identifiable by the use of words such as "believe," "expect," "anticipate," "should," "could," "would," "plans," "intend," "project," "estimate," "forecast," "may" or similar expressions. These forward-looking statements are subject to certain risks and uncertainties that could cause actual results to differ materially from those expressed in, or implied by, these statements. You are cautioned not to place undue reliance on any such forward-looking statements, which speak only as of the date made. Additionally, we undertake no obligation to update any statement in light of new information or future events, except as required under federal securities law.

Our ability to predict results or the actual effect of future plans or strategies is inherently uncertain. Factors that could have an impact on our ability to achieve operating results, growth plan goals and future prospects include, but are not limited to, the following:

·

the risks of mergers or branch sales (including the recent sale of our Florida banking operations and the acquisition of Denver Bankshares, Inc.), including, without limitation, the related time and costs of implementing such transactions, integrating operations as part of these transactions and possible failures to achieve expected gains, revenue growth and/or expense savings from such transactions;

·

credit quality deterioration, pronounced and sustained reduction in real estate market values, or other uncertainties, including the impact of inflationary pressures on economic conditions and our business, resulting in an increase in the allowance for credit losses, an increase in the credit loss expense, and a reduction in net earnings;

·	the effects of sustained high interest rates, including on our net income and the value of our securities portfolio;

·	changes in the economic environment, competition, or other factors that may affect our ability to acquire loans or influence the anticipated growth rate of loans and deposits and the quality of the loan portfolio and loan and deposit pricing;

·	fluctuations in the value of our investment securities;

·	governmental monetary and fiscal policies;

·	changes in and uncertainty related to benchmark interest rates used to price loans and deposits;

·	legislative and regulatory changes, including changes in banking, securities, trade, and tax laws and regulations and their application by our regulators and any changes in response to the recent failures of other banks;

·	the ability to attract and retain key executives and employees experienced in banking and financial services;

·	the sufficiency of the allowance for credit losses to absorb the amount of actual losses inherent in our existing loan portfolio;

·	our ability to adapt successfully to technological changes to compete effectively in the marketplace;

·	credit risks and risks from concentrations (by geographic area and by industry) within our loan portfolio;

·

the effects of competition from other commercial banks, thrifts, mortgage banking firms, consumer finance companies, credit unions, securities brokerage firms, insurance companies, money market and other mutual funds, financial technology companies, and other financial institutions operating in our markets or elsewhere or providing similar services;

·	the failure of assumptions underlying the establishment of allowances for credit losses and estimation of values of collateral and various financial assets and liabilities;

·	volatility of rate-sensitive deposits;

·	operational risks, including data processing system failures or fraud;

·	asset/liability matching risks and liquidity risks;

·	the costs, effects and outcomes of existing or future litigation;

·	changes in general economic, political, or industry conditions, nationally, internationally or in the communities in which we conduct business, including the risk of a recession;

·	changes in accounting policies and practices, as may be adopted by state and federal regulatory agencies and the Financial Accounting Standards Board;

·	war or terrorist activities, including the ongoing Israeli-Palestinian conflict and the Russian invasion of Ukraine, widespread disease or pandemic, or other adverse external events, which may cause deterioration in the economy or cause instability in credit markets;

·	the occurrence of fraudulent activity, breaches, or failures of our or our third-party vendors' information security controls or cyber-security related incidents, including as a result of sophisticated attacks using artificial intelligence and similar tools;

·	the imposition of tariffs or other domestic or international governmental policies impacting the value of the agricultural or other products of our borrowers;

·	potential changes in federal policy and at regulatory agencies, including as a result of federal elections;

·	the concentration of large deposits from certain clients who have balances above current FDIC insurance limits;

·	the effects of developments and events in the financial services industry, including the large-scale deposit withdrawals over a short period of time that resulted in bank failures during 2023; and

·	factors and risks described under the heading "Risk Factors" in our Annual Report on Form 10-K and in other reports we file with the SEC.

We qualify all of our forward-looking statements by the foregoing cautionary statements. Because of these risks and other uncertainties, our actual future results, performance or achievement, or industry results, may be materially different from the results indicated by these forward-looking statements. In addition, our past results of operations are not necessarily indicative of our future results.

The foregoing factors could cause results or performance to materially differ from those expressed in our forward-looking statements, should not be considered exhaustive, and should be read together with other cautionary statements that are included in this prospectus supplement, in the accompanying prospectus and in the documents incorporated herein by reference, including in our Annual Report on Form 10-K for the year ended December 31, 2023 and other filings we may make with the SEC, copies of which are available from us at no charge. New risks and uncertainties may emerge from time to time, and it is not possible for us to predict their occurrence or how they will affect us. If one or more of the factors affecting our forward-looking information and statements proves incorrect, then our actual results, performance, or achievements could differ materially from those expressed in, or implied by, forward-looking information and statements contained in this prospectus supplement. Therefore, we caution you not to place undue reliance on our forward-looking information and statements. We disclaim any duty to revise or update the forward-looking statements, whether written or oral, to reflect actual results or changes in the factors affecting the forward-looking statements, except as specifically required by law.

Recent Developments

Financial Highlights for the Two-Month Period Ended August 31, 2024

The following presents certain unaudited financial information as of and for the two-month period ended August 31, 2024. Our third quarter of 2024 has not yet concluded and the following results are preliminary in nature and based upon currently available information. In the opinion of management, such unaudited financial information includes all adjustments (consisting of normal recurring adjustments) necessary for a fair presentation of our financial position and results of operations for such periods, but may not include normal quarter-end adjustments. These results are also subject to further revision based upon final actual results for the entire quarter ending September 30, 2024, our review and the review of our independent auditors of such quarterly results and an audit by our independent auditors of our annual results for the year ended December 31, 2024. Therefore, no assurance can be given that, upon completion of our review and the review of our independent auditors, we will not report materially different financial results than those set forth below. In addition, we cannot assure you our results for this period will be indicative of our results for the entire quarter ending September 30, 2024 or for the entire year ending December 31, 2024.

As of September 30, 2024, the Company's non-performing assets are expected to be approximately $32.3 million (compared to the June 30, 2024 balance of $31.2 million), before the potential resolution of certain assets currently under contract for sale as discussed below. During the third quarter of 2024, non-performing assets with a book value of approximately $17.4 million were put under contract for sale through multiple transactions, with closing dates set for September 30, 2024. The successful closing of these sales would reduce the above total expected non-performing assets.

For the quarter ending September 30, 2024, the Company expects to report Net Charge-Offs and Credit Loss Expense of approximately $1.5 million - $2.0 million. Approximately $1.5 million of this quarter's Net Charge-Offs relate to the charge-off of a prior quarter's specific reserve against the non-performing assets under contract for sale discussed above.

For the quarter ending September 30, 2024, the Company expects to report net income of $8.6 - $8.8 million, excluding any realized losses relating to a potential balance sheet repositioning, a negative mortgage servicing right valuation adjustment of approximately $1.0 million pre-tax, and an approximately $1.2 million pre-tax expense from the resolution of an insurance claim relating to a prior wire fraud.

In any such case, you could lose all or a portion of your original investment. Further, additional risks and uncertainties not currently known to us or that we currently believe to be immaterial may also adversely affect us. This prospectus supplement also contains forward-looking statements that involve risks and uncertainties. See the section entitled "Special Note Regarding Forward-Looking Statements."

Risks Related to an Investment in Our Common Stock and the Offering

Future sales or the possibility of future sales of our common stock could depress the market price of our common stock.

Our amended and restated articles of incorporation authorize us to issue up to 30,000,000 shares of common stock. Following the completion of this offering, we will have issued and outstanding 20,120,468 shares of our common stock (or 20,772,518 shares if the underwriter exercises its option to purchase additional shares in full), a significant portion of which will be freely transferable without restriction or further registration under the Securities Act. Our executive officers and our directors holding, in the aggregate, approximately 490,999 shares of our common stock as of December 31, 2023 (representing approximately 3.1% of our outstanding shares of common stock as of such date), have agreed not to sell any shares of our common stock for a period of 90 days from the date of this prospectus supplement, or the Lock-Up Period, subject to certain exceptions. See the section entitled "Underwriting." Following the expiration of the Lock-Up Period, all of these shares will be eligible for resale under Rule 144 of the Securities Act, subject to any applicable holding period requirements and volume limitations. In addition, the underwriter, at any time and without notice, may release all or any portion of the common stock subject to such lock-up restrictions. The remaining shares of our common stock outstanding prior to this offering are not subject to lock-up agreements and may be freely resold at any time, subject to the restrictions described in this prospectus supplement, if applicable, for affiliate holders. The shares of our common stock being offered and sold in this offering will also generally be available for resale into the public markets. See the section entitled "Underwriting."

We may also issue additional shares in the future for various purposes without any action or approval by our shareholders, and these shares, once issued, will be available for sale into the public market, subject to the restrictions described in this prospectus supplement, if applicable, for affiliate holders. Actual or anticipated issuances or sales of substantial additional amounts of our common stock following this offering could cause the market price of our common stock to decline significantly and make it more difficult for us to sell equity or equity-related securities in the future on favorable terms, or at all. We cannot predict the size of future issuances of our common stock or the effect, if any, that future issuances and sales of our common stock will have on the market price of our common stock. Sales of substantial amounts of our common stock, or the perception that such sales could occur, may adversely affect prevailing market prices for our common stock. Further, a decline in the market price of our common stock might impede our ability to raise capital through the issuance of additional common stock or other equity securities.

The market price of our common stock may be volatile, and we may not be able to meet investor or analyst expectations. You may not be able to resell your shares at or above the price you paid and may lose part or all of your investment as a result.

Our stock price has fluctuated, as of close of market, from a low of $18.30 to a high of $35.20 between September 30, 2022 and September 24, 2024. Volatility in the market price of our common stock may negatively impact the price at which our common stock may be sold and may also negatively impact the timing of any sale. The market price of our common stock may continue to fluctuate widely in response to a variety of factors including the risk factors described herein and, among other things:

·	actual or anticipated variations in quarterly or annual operating results, financial conditions or credit quality;

·	changes in business or economic conditions;

·	changes in accounting standards, policies, guidance, interpretations or principles;

·	changes in recommendations or research reports about us or the financial services industry in general published by securities analysts;

·	the failure of securities analysts to cover, or to continue to cover, us;

·	changes in financial estimates or publication of research reports and recommendations by financial analysts or actions taken by rating agencies with respect to us or other financial institutions;

·	news reports relating to trends, concerns, and other issues in the financial services industry;

·	reports related to the impact of natural or man-made disasters in our market;

·	perceptions in the marketplace regarding us and or our competitors;

·	sudden increases in the demand for our common stock, including as a result of any "short squeezes;"

·	significant acquisitions or business combinations, strategic partnerships, joint ventures or capital commitments by or involving us or our competitors;

·	additional investments from third parties;

·	additions or departures of key personnel;

·	future sales or issuance of additional shares of our common stock;

·	fluctuations in the market price of our competitors' common stock and the operating results of our competitors;

·	changes or proposed changes in laws or regulations, or differing interpretations thereof, affecting our business, or enforcement of these laws or regulations;

·	new technology used, or services offered, by competitors;

·	additional investments from third parties; or

·	geopolitical conditions such as acts or threats of terrorism, pandemics or military conflicts.

In particular, the realization of any of the risks described in this section or under the heading "Risk Factors" in our Annual Report on Form 10-K for the year ended December 31, 2023, which is incorporated herein by reference, could have an adverse effect on the market price of our common stock and cause the value of your investment to decline. In addition, the stock market in general has experienced extreme volatility that has often been unrelated to the operating performance of particular companies. These broad market fluctuations may adversely affect the market price of our common stock over the short, medium or long term, regardless of our actual performance. If the market price of our common stock reaches an elevated level following this offering, it may materially and rapidly decline. In the past, following periods of volatility in the market price of a company's securities, shareholders have often instituted securities class action litigation. If we were to be involved in a class action lawsuit, it could divert the attention of our senior management and could adversely affect our business, financial condition and results of operations.

We depend on the Bank for cash flow, and the Bank's ability to make cash distributions is restricted, which could impact our ability to satisfy our obligations.

We are a bank holding company with no material activities other than activities incidental to holding the common stock of the Bank. Our principal source of funds to pay distributions on our common stock and service any of our obligations, other than further issuances of securities, is dividends received from the Bank. The holding company, MidWestOne Financial Group, Inc., is a legal entity separate and distinct from the Bank. Furthermore, the Bank is not obligated to pay dividends to us, and any dividends paid to us would depend on the earnings or financial condition of the Bank, various business considerations, and applicable law and regulation. As is generally the case for banking institutions, the profitability of the Bank is subject to the fluctuating cost and availability of money, changes in interest rates, and economic conditions in general. In addition, various federal and state statutes and regulations limit the amount of dividends that the Bank may pay to us without regulatory approval.

Our dividend policy may change without notice, we may not pay dividends on our common stock in the future, our ability to pay dividends is subject to certain restrictions, and we anticipate our ability to pay dividends may be subject to regulatory non-objection.

We have paid cash dividends on our common stock in every quarter since June 2008, after we became a registered public company. Prior to that, dividends were paid annually since incorporation in 1983. On July 23, 2024, we announced the declaration of a quarterly cash dividend of $0.2425 per share on our outstanding common stock. The dividend was payable September 17, 2024, to shareholders of record at the close of business on September 3, 2024.

Holders of our common stock are entitled to receive only such dividends as our board of directors may declare out of funds legally available for such payments. Our board of directors may, in its sole discretion, change the amount or frequency of dividends or discontinue the payment of dividends entirely. The timing, declaration, amount and payment of future cash dividends, if any, will be within the discretion of our board of directors and will depend upon then-existing conditions, including our results of operations, financial condition, capital requirements, investment opportunities, growth opportunities, any legal, regulatory, contractual or other limitations on our ability to pay dividends and other factors our board of directors may deem relevant.

In addition, we are a bank holding company, and our ability to declare and pay dividends is dependent on federal regulatory considerations, including the guidelines of the Federal Reserve regarding capital adequacy and dividends. It is the policy of the Federal Reserve that bank holding companies should generally pay dividends on common stock only out of earnings, and only if prospective earnings retention is consistent with the organization's expected future needs, asset quality and financial condition, and that bank holding companies should inform and consult with the Federal Reserve in advance of declaring and paying a dividend that exceeds earnings for the period for which the dividend is being paid. Any future payment of dividends will depend on the Bank's ability to make distributions and payments to the Company, as these distributions and payments are our principal source of funds to pay dividends. As a general matter, the Federal Reserve has indicated that the board of directors of a bank holding company (including a financial holding company) should eliminate, defer or significantly reduce the company's dividends if: (i) the company's net income available to shareholders for the past four quarters, net of dividends previously paid during that period, is not sufficient to fully fund the dividends; (ii) the prospective rate of earnings

retention is inconsistent with the company's capital needs and overall current and prospective financial condition; or (iii) the company will not meet, or is in danger of not meeting, its minimum regulatory capital adequacy ratios.

The ability of the Bank to pay dividends to us is also limited by its obligations to maintain sufficient capital and liquidity and by other legal, regulatory and general restrictions on dividends that are applicable to the Bank, including the requirement under the Iowa Banking Act that the Bank may not pay dividends in excess of its undivided profits. Also, banking institutions that do not maintain a capital conservation buffer, comprised of Common Equity Tier 1 Capital of 2.5%, above the regulatory minimum capital requirements will face constraints on the payment of dividends, stock repurchases and discretionary bonus payments to executive officers based on the amount of the shortfall, unless prior regulatory approval is obtained. Accordingly, if the Bank fails to maintain the applicable minimum capital ratios and the capital conservation buffer, distributions to us may be prohibited or limited, and if we fail to maintain the applicable minimum capital ratios and the capital conservation buffer, distributions to or stock repurchases from our shareholders may be prohibited or limited.

If the Company effectuates the restructuring transactions as anticipated and as disclosed under the heading "Use of Proceeds," it is likely that the losses realized from the sale of securities will be greater than the Company's income over the past four quarters. As a result, the Company would be required to seek the Federal Reserve's non-objection prior to declaring dividends on its shares of common stock at least through 2025. It is possible that the Federal Reserve would not provide such non-objection, and therefore that the Company would be unable to declare and pay any cash dividends on its common stock.

In addition, in the future, we may enter into borrowing or other contractual arrangements that restrict our ability to pay dividends. As a consequence of these various limitations and restrictions, we may not be able to make, or may have to reduce or eliminate, the payment of dividends on our common stock. Any change in the level of our dividends or the suspension of the payment thereof could have an adverse effect on the market price of our common stock. See also "Item 1. Business-Supervision and Regulation of the Company-Dividend Payments" and "Item 1. Business-Supervision and Regulation of the Bank-Dividend Payments" in our Annual Report on Form 10-K for the year ended December 31, 2023, which is incorporated by reference into this prospectus supplement.

The holders of our debt obligations and preferred stock will have priority over our common stock with respect to payment in the event of liquidation, dissolution or winding up and with respect to the payment of interest and dividends.

In any liquidation, dissolution or winding up of the Company, our common stock would rank below all claims of debt holders against us as well as any preferred stock that has been issued. As of June 30, 2024, we had outstanding an aggregate of $42.4 million of junior subordinated debentures held by five statutory business trusts that we control, $64.2 million of subordinated notes, net of debt issuance costs, and a $7.5 million note payable to an unaffiliated bank. We currently have no outstanding preferred stock, but are authorized to issue up to 500,000 shares of preferred stock under our amended and restated articles of incorporation. We could incur future debt obligations or issue preferred stock in the future to raise additional capital. In such event, holders of our common stock will not be entitled to receive any payment or other distribution of assets upon the liquidation, dissolution or winding up of the Company until after our obligations to the debt holders are satisfied and holders of subordinated debt and senior equity securities, including preferred shares, if any, have received any payment or distribution due to them. In addition, we are required to pay interest on the subordinated notes and dividends on the trust preferred securities and preferred stock before we are able to pay any dividends on our common stock. Since any decision to issue debt securities or incur other borrowings in the future will depend on market conditions and other factors beyond our control, the amount, timing, nature or success of our future capital raising efforts is uncertain. Thus, holders of our common stock bear the risk that our future issuances of debt securities or our incurrence of other borrowings will negatively affect the market price of our common stock.

Our management will have broad discretion in allocating the net proceeds of the offering. Our failure to effectively utilize such net proceeds may have an adverse effect on our financial performance and the value of our common stock.

We intend to invest all of the net proceeds from this offering into MidWestOne Bank, our wholly-owned subsidiary, to support the Bank's capital ratios in connection with the potential

repositioning of a substantial portion of our available-for-sale and held-to-maturity securities portfolio, as described under the heading "Use of Proceeds." The repositioning transactions and their results, as well as their outcome for MidWestOne and the Bank, will be subject to market conditions and other factors. If we do not complete the repositioning transactions, or if the repositioning transactions do not have the anticipated results, then we may not fully realize the anticipated benefits of transactions and any new capital raised may not be deployed as effectively as possible to increase profitability and growth. As a result, the market price of our common stock may be adversely affected.

Iowa law and the provisions of our amended and restated articles of incorporation and amended and restated bylaws may have an anti-takeover effect, and there are substantial regulatory limitations on changes of control of bank holding companies.

Iowa corporate law and certain provisions of our amended and restated articles of incorporation and our amended and restated bylaws could make it more difficult for a third party to acquire us, even if doing so would be perceived to be beneficial by our shareholders. Furthermore, with certain limited exceptions, federal regulations prohibit a person or company or a group of persons deemed to be "acting in concert" from, directly or indirectly, acquiring 10% or more (5% or more if the acquirer is a bank holding company) of any class of our voting stock or obtaining the ability to control in any manner the election of a majority of our directors or otherwise direct the management or policies of our Company without prior notice or application to and the approval of the Federal Reserve. Accordingly, prospective investors must comply with these requirements, if applicable, in connection with any purchase of shares of our common stock. Collectively, provisions of our amended and restated articles of incorporation and amended and restated bylaws and other statutory and regulatory provisions may delay, prevent, or deter a merger, acquisition, tender offer, proxy contest, or other transaction that might otherwise result in our shareholders receiving a premium over the market price for their common stock. Moreover, the combination of these provisions effectively inhibits certain business combinations, which, in turn, could adversely affect the market price of our common stock.

An investment in our common stock is not an insured deposit and is not guaranteed by the FDIC, so you could lose some or all of your investment.

An investment in our common stock is not a bank deposit and, therefore, is not insured against loss or guaranteed by the FDIC, any other deposit insurance fund or by any other public or private entity. Investment in our common stock is inherently risky for the reasons described herein, and is subject to the same market forces that affect the price of common stock in any company. As a result, if you acquire our common stock, you could lose some or all of your investment.

Risks Relating to Our Business and our Industry and Regulation

For risks associated with our business and industry, see the section entitled "Risk Factors" in our Annual Report on Form 10-K for the year ended December 31, 2023, which is incorporated into this prospectus supplement by reference, as the same may be updated from time to time prior to the completion of this offering by our future filings under the Exchange Act.

USE OF PROCEEDS

We estimate that the net proceeds to us from this offering will be approximately $103.1 million, or approximately $118.6 million if the underwriter exercises in full its option to purchase additional shares, in each case, after deducting underwriting discounts and commissions and the estimated offering expenses payable by us.

We intend to invest all of the net proceeds from this offering into MidWestOne Bank, our wholly-owned subsidiary, to support the Bank's capital ratios in connection with the potential repositioning of a substantial portion of our available-for-sale and held-to-maturity debt securities portfolio. The timing and execution of the repositioning will be dependent on market conditions, although we anticipate that we will complete the repositioning before the end of the fourth quarter of 2024. We expect that this repositioning will involve the following:

·

The sale of debt securities with an amortized cost basis of $1.21 billion as of June 30, 2024, and an unrealized pre-tax loss of $176.1 million as of June 30, 2024. The securities we anticipate selling have a weighted average life of approximately 5.5 years, carry an average yield of approximately 1.73% as of June 30, 2024, and the majority were purchased prior to 2022. Based upon our current estimates of market pricing, we expect to recognize a pre-tax loss related to the repositioning of approximately $160.0 million in the third quarter of 2024;

·	The full repayment of $405.0 million of borrowings outstanding under the Federal Reserve Bank Term Funding Program as well as $8.8 million of accrued interest thereon as of June 30, 2024; and

·

The subsequent purchase of debt securities with current-market yields. Depending on the amount of funds available from the sale of our debt securities, we expect to purchase approximately $616.0 million of new debt securities to be classified as available-for-sale securities. Based on current market rates, we estimate the new securities would have an estimated aggregate yield of approximately 4.54%, but the actual yield will depend on market conditions at the time of purchase.

We expect that the new securities purchased will have a lower regulatory risk weighting than the securities sold in the repositioning. This change in regulatory risk weighting, the reduction in the size of the investment portfolio, and the net proceeds of the offering, would have resulted in a pro forma Tier 1 capital ratio, on a consolidated basis, of approximately 10.5% as of June 30, 2024.

We intend to undertake the repositioning transactions outlined above with the objective of increasing the profitability of our investment portfolio, improving liquidity, strengthening our capital position and supporting future growth. The repositioning transactions and their results, as well as their outcomes for MidWestOne and the Bank, will be subject to market conditions and other factors. Our board of directors and management will have broad discretion in the application of the net proceeds from this offering, and investors will be relying on the judgment of our board of directors and management with regard to the use of these net proceeds.

CAPITALIZATION

The following table sets forth our capitalization as of June 30, 2024:

·	on an actual basis; and

·

on an as adjusted basis to reflect the sale of 4,347,000 shares of our common stock offered by us at the public offering price of $25.00 per share in this offering, after deducting the underwriting discount and our estimated offering expenses (assuming the underwriter's option to purchase additional shares from us is not exercised).

The "As Adjusted" information presented does not reflect results of the potential balance sheet repositioning described in more detail under the heading "Use of Proceeds."

MATERIAL U.S. FEDERAL INCOME TAX CONSIDERATIONS TO NON-U.S. HOLDERS

The following discussion is a summary of the material U.S. federal income tax consequences of the purchase, ownership and disposition of our common stock by Non-U.S. Holders (as defined below) that acquire our common stock in this offering and hold it as a capital asset. This discussion does not purport to be a complete analysis of all potential tax effects. The effects of other U.S. federal tax laws, such as estate and gift tax laws, and any applicable state, local or non-U.S. tax laws are not discussed. This discussion is based on the United States Internal Revenue Code of 1986, as amended, or the Code, Treasury regulations promulgated thereunder, or the Treasury Regulations, judicial decisions, and published rulings and administrative pronouncements of the Internal Revenue Service, or the IRS, in each case in effect as of the date of this prospectus supplement. These authorities may change or be subject to differing interpretations at any time. Any such change or differing interpretation may be applied retroactively in a manner that could adversely affect a Non-U.S. Holder of our common stock. We have not sought and will not seek any rulings from the IRS regarding the statements made and the conclusions reached in the discussion below. There can be no assurance the IRS or a court will agree with our position discussed below regarding the U.S. federal income tax consequences of the purchase, ownership and disposition of our common stock. We cannot assure you that a change in law will not significantly alter the tax considerations described in this discussion.

This discussion does not address all U.S. federal income tax consequences relevant to a Non-U.S. Holder's particular circumstances, including the alternative minimum tax and the impact of the Medicare contribution tax on net investment income. In addition, it does not address consequences relevant to Non-U.S. Holders subject to special rules, including, without limitation:

·	U.S. expatriates and former citizens or long-term residents of the United States;

·	persons who have elected to mark securities to market or who hold our common stock as part of a hedge, straddle or other risk reduction strategy or as part of a conversion transaction or other integrated investment;

·	banks, insurance companies, and other financial institutions;

·	brokers, dealers or traders in securities;

·	corporations that accumulate earnings to avoid U.S. federal income tax;

·	tax-exempt organizations, pension plans, tax-qualified retirement plans, or governmental organizations; and

·	persons deemed to sell our common stock under the constructive sale provisions of the Code.

If an entity treated as a partnership for U.S. federal income tax purposes holds our common stock, the tax treatment of a partner in the partnership will depend on the status of the partner and the activities of the partnership. Accordingly, partnerships holding our common stock and the partners in such partnerships should consult their tax advisors regarding the U.S. federal income tax consequences to them.

THIS DISCUSSION IS FOR INFORMATION PURPOSES ONLY AND IS NOT TAX ADVICE. INVESTORS SHOULD CONSULT THEIR TAX ADVISORS WITH RESPECT TO THE APPLICATION OF THE U.S. FEDERAL INCOME TAX LAWS TO THEIR PARTICULAR SITUATIONS AS WELL AS ANY TAX CONSEQUENCES OF THE PURCHASE, OWNERSHIP AND DISPOSITION OF OUR COMMON STOCK ARISING UNDER THE U.S. FEDERAL ESTATE OR GIFT TAX LAWS OR UNDER THE LAWS OF ANY STATE, LOCAL OR NON-U.S. TAXING JURISDICTION OR UNDER ANY APPLICABLE INCOME TAX TREATY.

Definition of a Non-U.S. Holder

For purposes of this discussion, a "Non-U.S. Holder" is any beneficial owner of our common stock that is, for U.S. federal income tax purposes:

·	a non-resident alien;

·	a corporation (or any other entity treated as a corporation for U.S. federal income tax purposes) that is not created or organized under the laws of the United States, any state thereof, or the District of Columbia;

·	an estate, the income of which is not subject to U.S. federal income taxation regardless of its source; or

·

a trust that does not have in effect a valid election under the Treasury Regulations, to be treated as a United States person and either (i) no court within the United States is able to exercise primary supervision over the trust's administration or (ii) no "United States person" (within the meaning of Section 7701(a)(30) of the Code) has the authority to control all substantial decisions of that trust.

Distributions on Common Stock

Distributions of cash or property on our common stock will generally constitute dividends for U.S. federal income tax purposes to the extent of our current or accumulated earnings and profits, as determined under U.S. federal income tax principles. Amounts not treated as dividends for U.S. federal income tax purposes will first constitute a tax-free retuof capital to the extent of a Non-U.S. Holder's adjusted tax basis in its common stock and thereafter capital gain, which is subject to the tax treatment described below in the section entitled "-Sale or Other Taxable Disposition".

Subject to the discussion below on effectively connected income, dividends paid to a Non-U.S. Holder will generally be subject to U.S. federal withholding tax at a rate of 30% of the gross amount of the dividends or such lower rate specified by an applicable income tax treaty. To receive a reduced withholding rate, a Non-U.S. Holder must furnish a valid IRS Form W-8BEN or W-8BEN-E (or other applicable documentation) certifying qualification for the lower treaty rate. A Non-U.S. Holder that holds our common stock through a financial institution or other agent will be required to provide appropriate documentation to the financial institution or other agent, which then will be required to provide certification to us or our paying agent either directly or through other intermediaries. A Non-U.S. Holder that does not timely furnish the required documentation, but that qualifies for a reduced income tax treaty rate, may obtain a refund of any excess amounts withheld by timely filing an appropriate claim for refund with the IRS.

If dividends paid to a Non-U.S. Holder are effectively connected with the Non-U.S. Holder's conduct of a trade or business within the United States (and, as provided by an applicable income tax treaty, attributable to a permanent establishment or fixed base maintained by the Non-U.S. Holder in the United States), the Non-U.S. Holder will be exempt from the U.S. federal withholding tax described above. To claim the exemption, the Non-U.S. Holder must furnish to the applicable withholding agent a valid IRS Form W-8ECI, certifying that the dividends are effectively connected with the Non-U.S. Holder's conduct of a trade or business within the United States.

Any such effectively connected dividends will be subject to U.S. federal income tax on a net income basis at the regular rates that also apply to U.S. persons. A Non-U.S. Holder that is a corporation also may be subject to a branch profits tax at a rate of 30% (or such lower rate specified by an applicable income tax treaty) on such effectively connected dividends, as adjusted for certain items. Non-U.S. Holders should consult their tax advisors regarding any applicable tax treaties that may provide for different rules.

Sale or Other Taxable Disposition

A Non-U.S. Holder generally will not be subject to U.S. federal income tax on any gain realized upon the sale or other taxable disposition of our common stock unless:

·	the gain is effectively connected with the Non-U.S. Holder's conduct of a trade or business within the United States (and, as provided by an applicable income tax treaty, attributable to a permanent establishment or fixed base maintained by the Non-U.S. Holder in the United States);

·	the Non-U.S. Holder is a nonresident alien individual present in the United States for 183 days or more during the taxable year of the disposition and certain other requirements are met; or

·

we are or have been a U.S. real property holding corporation, or USRPHC, for U.S. federal income tax purposes at any time within the shorter of the five-year period preceding such disposition or such Non-U.S. Holder's holding period for our common stock, or the relevant period, and the Non-U.S. Holder (i) disposes

of our common stock during a calendar year when our common stock is no longer regularly traded on an established securities market or (ii) owned (directly, indirectly and constructively) more than 5% of our common stock at any time during the relevant period.

Gain described in the first bullet point above generally will be subject to U.S. federal income tax on a net income basis at the regular rates in the same manner as if such holder were a resident of the United States. A Non-U.S. Holder that is a corporation also may be subject to a branch profits tax at a rate of 30% (or such lower rate specified by an applicable income tax treaty) on such effectively connected gain, as adjusted for certain items.

A Non-U.S. Holder described in the second bullet point above will be subject to U.S. federal income tax at a rate of 30% (or such lower rate specified by an applicable income tax treaty), which may be offset by U.S. source capital losses of the Non-U.S. Holder for the year, provided the Non-U.S. Holder has timely filed U.S. federal income tax returns with respect to such losses.

With respect to the third bullet point above, we believe we currently are not, and do not anticipate becoming, a USRPHC. Because the determination of whether we are a USRPHC depends, however, on the fair market value of our United States real property interests as defined in the Code relative to the fair market value of our non-U.S. real property interests and our other business assets, there can be no assurance we currently are not a USRPHC or will not become one in the future. Gain from a disposition of our common stock described in the third bullet point above will be subject to tax generally as if the gain were effectively connected with the conduct of a trade or business in the United States, except that the "branch profits tax" will not apply.

Information Reporting and Backup Withholding

Payments of dividends on our common stock and the payment of the proceeds from the sale of our common stock effected at a U.S. office of a broker generally will not be subject to backup withholding and the payment of proceeds from the sale of our common stock effected at a U.S. office of a broker will generally not be subject to information reporting, provided the applicable withholding agent does not have actual knowledge or reason to know the Non-U.S. Holder is a United States person and the Non-U.S. Holder either certifies its non-U.S. status, such as by furnishing a valid IRS Form W-8BEN or W-8BEN-E or other documentation upon which it may rely to treat the payments as made to a non-U.S. person in accordance with Treasury Regulations, or otherwise establishes an exemption.

However, we are required to file information returns with the IRS in connection with any distribution on our common stock paid to the Non-U.S. Holder, regardless of whether any tax was actually withheld. Copies of information returns that are filed with the IRS may also be made available under the provisions of an applicable treaty or agreement to the tax authorities of the country in which the Non-U.S. Holder resides or is established.

Payment of the proceeds from the sale of our common stock effected at a foreign office of a broker generally will not be subject to information reporting or backup withholding. However, a sale of our common stock by a Non-U.S. Holder that is effected at a foreign office of a broker will be subject to information reporting and backup withholding if (i) the proceeds are transferred to an account maintained by the Non-U.S. Holder in the United States, (ii) the payment of proceeds or the confirmation of the sale is mailed to the Non-U.S. Holder at a U.S. address or (iii) the sale has some other specified connection with the United States as provided in the Treasury Regulations, unless, in each case, the broker does not have actual knowledge or reason to know that the holder is a United States person and the documentation requirements described above are met or the Non-U.S. Holder otherwise establishes an exemption.

In addition, a sale of our common stock will be subject to information reporting if it is effected at a foreign office of a broker that is (i) a United States person, (ii) a "controlled foreign corporation" for U.S. federal income tax purposes, (iii) a foreign person 50% or more of whose gross income is effectively connected with the conduct of a U.S. trade or business for a specified three-year period or (iv) a foreign partnership, if at any time during its tax year (a) one or more of its partners are "U.S. persons," as defined in the Treasury Regulations, who in the aggregate hold more than 50% of the income or capital interest in the partnership or (b) such foreign partnership is engaged in the conduct of a trade or business in the United States, in each case unless the broker does not have actual knowledge or reason to know that the holder is a United States person and the documentation requirements described above are

met or an exemption is otherwise established. Backup withholding will apply if the sale is subject to information reporting and the broker has actual knowledge that the holder is a United States person.

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules may be allowed as a refund or a credit against a Non-U.S. Holder's U.S. federal income tax liability, provided the required information is timely furnished to the IRS.

FATCA Withholding

Sections 1471 through 1474 of the Code and the Treasury Regulations issued thereunder (commonly referred to as the Foreign Account Tax Compliance Act, or FATCA) generally impose a 30% withholding tax on dividends paid on our shares to, and (subject to the proposed Treasury Regulations discussed below) the gross proceeds derived from the sale or other disposition of our shares by, a foreign entity if the foreign entity is:

·

a "foreign financial institution" (as defined under FATCA) that does not furnish proper documentation, typically on IRS Form W-8BEN-E, evidencing either (i) an exemption from FATCA withholding or (ii) its compliance (or deemed compliance) with specified due diligence, reporting, withholding and certification obligations under FATCA or (iii) residence in a jurisdiction that has entered into an intergovernmental agreement with the United States relating to FATCA and compliance with the diligence and reporting requirements of the intergovernmental agreement and local implementing rules; or

·	a "non-financial foreign entity" (as defined under FATCA) that does not provide sufficient documentation, typically on IRS Form W-8BEN-E, evidencing either (i) an exemption from FATCA or (ii) adequate information regarding substantial United States beneficial owners of such entity (if any).

Withholding under FATCA generally applies to payments of dividends on our shares and to payments of gross proceeds from a sale or other disposition of our shares. Withholding agents may, however, rely on proposed Treasury Regulations that would no longer require FATCA withholding on payments of gross proceeds. A withholding agent such as a broker, and not the Bank, will determine whether or not to implement gross proceeds FATCA withholding.

If a dividend payment is subject to withholding both under FATCA and the withholding tax rules discussed above in the section entitled "-Distributions on Common Stock," the withholding under FATCA may be credited against, and therefore reduce, such other withholding tax. Holders of shares should consult their own tax advisors regarding these requirements and whether they may be relevant to their ownership and disposition of the shares.

Under certain circumstances, a Non-U.S. Holder might be eligible for refunds or credits of withholding taxes imposed under FATCA by filing a United States federal income tax return. Prospective investors should consult their tax advisors regarding the effect of FATCA on their ownership and disposition of our common stock.

THE PRECEDING DISCUSSION IS FOR GENERAL INFORMATION PURPOSES ONLY AND IS NOT TAX ADVICE. PROSPECTIVE INVESTORS SHOULD CONSULT THEIR TAX ADVISORS WITH RESPECT TO THE APPLICATION OF THE U.S. FEDERAL INCOME TAX LAWS TO THEIR PARTICULAR SITUATIONS AS WELL AS ANY TAX CONSEQUENCES OF THE PURCHASE, OWNERSHIP AND DISPOSITION OF OUR COMMON STOCK ARISING UNDER THE U.S. FEDERAL ESTATE OR GIFT TAX LAWS OR UNDER THE LAWS OF ANY STATE, LOCAL OR NON-U.S. TAXING JURISDICTION OR UNDER ANY APPLICABLE INCOME TAX TREATY.

UNDERWRITING

We are offering the shares of our common stock described in this prospectus supplement in an underwritten offering in which we and Keefe, Bruyette & Woods, Inc., as underwriter, are entering into an underwriting agreement with respect to the shares of our common stock being offered hereby. Subject to certain conditions, we will agree to sell, and the underwriter will agree to purchase, 4,347,000 shares of our common stock.

The underwriter is offering the shares of our common stock subject to a number of conditions, including receipt and acceptance of our common stock by the underwriter. The obligations of the underwriter to pay for and accept delivery of the shares offered by this prospectus supplement are subject to these conditions. The underwriting agreement between us and the underwriter provides that if the underwriter defaults, this offering may be terminated.

In connection with this offering, the underwriter or securities dealers may distribute offering documents to investors electronically. See the section entitled "-Electronic Distribution."

Certain of our directors, executive officers and their related persons or entities have indicated an interest in purchasing a portion of the shares of common stock in this offering at a price equal to the public offering price. Because this indication of interest is not a binding agreement or commitment to purchase, these persons could determine to purchase more, less or no shares in this offering or the underwriter could determine to sell more, less or no shares to these persons.

Underwriting Discount

Shares of our common stock sold by the underwriter to the public will be offered at the public offering price set forth on the cover of this prospectus supplement. Any shares of our common stock sold by the underwriter to securities dealers may be sold at a discount of up to $0.7125 per share from the public offering price. Any of these securities dealers may resell any shares of our common stock purchased from the underwriter to other brokers or dealers at a discount of up to $0.2375 per share from the public offering price. If all of the shares of our common stock are not sold at the public offering price, the representative may change the offering price and the other selling terms. Sales of shares of our common stock made outside of the United States may be made by affiliates of the underwriter. The underwriter reserves the right to reject an order for the purchase of shares, in whole or in part.

The underwriting fee is equal to the public offering price per share of common stock less the amount paid by the underwriter to us per share of common stock. The underwriting fee is $1.1875 per share. The per share and total underwriting discount to be paid to the underwriter, assuming no exercise of the underwriter's option to purchase additional shares, is $1.1875 and $5,162,062.50, respectively, and assuming full exercise of the underwriter's option to purchase additional shares, is $1.1875 and $5,936,371.875, respectively.

We estimate the expenses of this offering, not including the underwriting discount, to be approximately $285,000, and such expenses are payable by us. We also have agreed to reimburse the underwriter for its expenses incurred in connection with the offering in an amount up to $150,000.

Option to Purchase Additional Shares

We have granted the underwriter an option to purchase up to 652,050 additional shares of our common stock, at the public offering price set forth on the cover page of this prospectus supplement, less the underwriting discount. The underwriter may exercise this option, in whole or in part, from time to time for a period of 30 days from the date of this prospectus supplement.

Lock-Up Agreements

We, our executive officers and directors are entering into lock-up agreements with the underwriter. Under these agreements, we and each of these persons may not, without the prior written approval of the representative and subject to certain exceptions:

·

offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant for the sale of, or otherwise dispose of or transfer any shares of our common stock or any securities convertible into or exchangeable or exercisable for our common stock, whether now owned or hereafter acquired or with respect to which such person has or hereafter acquires the power of disposition, or exercise any right with respect to the registration thereof, or file or cause to be filed any registration statement under the Securities Act, with respect to any of the foregoing;

·

enter into any swap, hedge, or any other agreement or any transaction that transfers, in whole or in part, directly or indirectly, the economic consequence of ownership of the shares of our common stock or such other securities, whether any such swap or transaction is to be settled by delivery of shares of our common stock or other securities, in cash or otherwise; or

·	publicly disclose the intention to make any such offer, pledge, sale or disposition, or to enter into any such swap, hedge, transaction or other arrangement.

These restrictions are subject to customary exceptions and will be in effect for a period of 90 days after the date of this prospectus supplement. At any time and without public notice, the representative may, in their sole discretion, waive or release all or some of the securities from these lock-up agreements.

These restrictions also apply to securities convertible into or exchangeable or exercisable for or repayable with our common stock to the same extent as they apply to our common stock. They also apply to common stock owned now or later acquired by the person executing the agreement or for which the person executing the agreement later acquires the power of disposition.

Exchange Listing

Our common stock is listed on Nasdaq under the symbol "MOFG."

Indemnification and Contribution

We have agreed to indemnify the underwriter and its affiliates, selling agents, and controlling persons against certain liabilities, including under the Securities Act. If we are unable to provide this indemnification, we will contribute to the payments the underwriter and its affiliates, selling agents, and controlling persons may be required to make in respect of those liabilities.

Price Stabilization, Short Positions, and Penalty Bids

To facilitate this offering and in accordance with Regulation M under the Exchange Act, the underwriter may engage in transactions that stabilize, maintain, or otherwise affect the price of our common stock, including:

·	stabilizing transactions;

·	short sales; and

·	purchase to cover positions created by short sales.

Stabilizing transactions consist of bids or purchases made for the purpose of preventing or retarding a decline in the market price of our common stock while this offering is in progress. These transactions may also include making short sales of our common stock, which involves the sale by the underwriter of a greater number of shares of common stock than it is required to purchase in this offering. Short sales may be "covered short sales," which are short positions in an amount not greater than the underwriter's purchase option referred to above, or may be "naked short sales," which are short positions in excess of that amount.

The underwriter may close out any covered short position either by exercising its purchase option, in whole or in part, or by purchasing shares in the open market. In making this determination, the underwriter will consider, among other things, the price of shares available for purchase in the open market compared to the price at which it may purchase shares through the purchase option described above. The underwriter must close out any naked short position by purchasing shares in the open market. A naked short position is more likely to be created if the underwriter is concerned that there may be downward pressure on the price of our common stock in the open market that could adversely affect investors who purchased in this offering.

As an additional means of facilitating our public offering, the underwriter may bid for, and purchase, shares of our common stock in the open market. The underwriter also may reclaim selling concessions allowed to an underwriter or a dealer for distributing shares of our common stock in this offering, if it repurchases previously distributed shares of our common stock to cover short positions or to stabilize the price of our common stock.

As a result of these activities, the price of our common stock may be higher than the price that otherwise might exist in the open market. If these activities are commenced, they may be discontinued by the underwriter at any time without notice. The underwriter may carry out these transactions on Nasdaq, in the over-the-counter market or otherwise.

Electronic Distribution

A prospectus supplement in electronic format may be made available by e-mail or on the websites or through online services maintained by the underwriter or its affiliates. In those cases, prospective investors may view offering terms online and may be allowed to place orders online. The underwriter may agree with us to allocate a specific number of shares for sale to online brokerage account holders. Any such allocation for online distributions will be made by the underwriter on the same basis as other allocations. Other than the prospectus supplement in electronic format, the information on the underwriter's websites and any information contained on any other website maintained by the underwriter is not part of this prospectus supplement, has not been approved and/or endorsed by the underwriter or us, and should not be relied upon by investors.

Affiliations

The underwriter and its respective affiliates are full service financial institutions engaged in various activities, which may include securities trading, commercial and investment banking, financial advisory, investment management, investment advisory, investment research, principal investment, hedging, financing, loan referrals, valuation, and brokerage activities. From time to time, the underwriter and/or its respective affiliates have directly and indirectly engaged, and may in the future engage, in various financial advisory, investment banking loan referrals, and commercial banking services with us and our affiliates, for which they received or paid, or may

receive or pay, customary compensation, fees, and expense reimbursement. In the ordinary course of their various business activities, the underwriter and its respective affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers, and those investment and securities activities may involve securities and/or instruments of ours. The underwriter and its respective affiliates may also make investment recommendations and/or publish or express independent research views in respect of those securities or instruments and may at any time hold, or recommend to clients that they acquire, long and/or short positions in those securities and instruments.

RISK FACTORS

An investment in our securities involves a high degree of risk. Before making an investment decision, you should carefully read and consider the risk factors incorporated by reference in this prospectus, as well as those contained in any applicable prospectus supplement, as the same may be updated from time to time by our future filings with the SEC. You should also refer to other information contained or incorporated by reference in this prospectus and any applicable prospectus supplement, including our financial statements and the related notes incorporated by reference herein. Our business, financial condition, results of operations or growth prospects could be materially adversely affected by any of these risks. The trading price of our securities could decline due to any of these risks, and

you may lose all or part of your investment. This prospectus and documents incorporated by reference in this prospectus also contain forward-looking statements that involve risks and uncertainties. Our actual results could differ materially from those anticipated in these forward-looking statements as a result of certain factors, including the risks faced by us. Additional risks and uncertainties not known to us or that we deem immaterial may also materially and adversely affect our business and operations.

SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

This prospectus contains certain "forward-looking statements" within the meaning of such term in the Private Securities Litigation Reform Act of 1995. We and our representatives may, from time to time, make written or oral statements that are "forward-looking" and provide information other than historical information. These statements involve known and unknown risks, uncertainties and other factors that may cause actual results to be materially different from any results, levels of activity, performance or achievements expressed or implied by any forward-looking statement. These factors include, among other things, the factors listed below.

Forward-looking statements, which may be based upon beliefs, expectations and assumptions of our management and on information currently available to management, are generally identifiable by the use of words such as "believe," "expect," "anticipate," "should," "could," "would," "plans," "intend," "project," "estimate," "forecast," "may" or similar expressions. These forward-looking statements are subject to certain risks and uncertainties that could cause actual results to differ materially from those expressed in, or implied by, these statements. Readers are cautioned not to place undue reliance on any such forward-looking statements, which speak only as of the date made. Additionally, we undertake no obligation to update any statement in light of new information or future events, except as required under federal securities law.

Our ability to predict results or the actual effect of future plans or strategies is inherently uncertain. Factors that could have an impact on our ability to achieve operating results, growth plan goals and future prospects include, but are not limited to, the following:

●

the risks of mergers or branch sales (including the recent sale of our Florida banking operations and the acquisition of Denver Bancshares, Inc.), including, without limitation, the related time and costs of implementing such transactions, integrating operations as part of these transactions and possible failures to achieve expected gains, revenue growth and/or expense savings from such transactions;

●

credit quality deterioration, pronounced and sustained reduction in real estate market values, or other uncertainties, including the impact of inflationary pressures on economic conditions and our business, resulting in an increase in the allowance for credit losses, an increase in the credit loss expense, and a reduction in net earnings;

●	the effects of sustained high interest rates, including on our net income and the value of our securities portfolio;

●	changes in the economic environment, competition, or other factors that may affect our ability to acquire loans or influence the anticipated growth rate of loans and deposits and the quality of the loan portfolio and loan and deposit pricing;

●	fluctuations in the value of our investment securities;

●	governmental monetary and fiscal policies;

●	changes in and uncertainty related to benchmark interest rates used to price loans and deposits;

●	legislative and regulatory changes, including changes in banking, securities, trade, and tax laws and regulations and their application by our regulators and any changes in response to the recent failures of other banks;

●	the ability to attract and retain key executives and employees experienced in banking and financial services;

●	the sufficiency of the allowance for credit losses to absorb the amount of actual losses inherent in our existing loan portfolio;

●	our ability to adapt successfully to technological changes to compete effectively in the marketplace;

●	credit risks and risks from concentrations (by geographic area and by industry) within our loan portfolio;

●

the effects of competition from other commercial banks, thrifts, mortgage banking firms, consumer finance companies, credit unions, securities brokerage firms, insurance companies, money market and other mutual funds, financial technology companies, and other financial institutions operating in our markets or elsewhere or providing similar services;

●	the failure of assumptions underlying the establishment of allowances for credit losses and estimation of values of collateral and various financial assets and liabilities;

●	volatility of rate-sensitive deposits;

●	operational risks, including data processing system failures or fraud;

●	asset/liability matching risks and liquidity risks;

●	the costs, effects and outcomes of existing or future litigation;

●	changes in general economic, political, or industry conditions, nationally, internationally or in the communities in which we conduct business, including the risk of a recession;

●	changes in accounting policies and practices, as may be adopted by state and federal regulatory agencies and the Financial Accounting Standards Board;

●	war or terrorist activities, including the ongoing Israeli-Palestinian conflict and the Russian invasion of Ukraine, widespread disease or pandemic, or other adverse external events, which may cause deterioration in the economy or cause instability in credit markets;

●	the occurrence of fraudulent activity, breaches, or failures of our or our third-party vendors' information security controls or cyber-security related incidents, including as a result of sophisticated attacks using artificial intelligence and similar tools;

●	the imposition of tariffs or other domestic or international governmental policies impacting the value of the agricultural or other products of our borrowers;

DESCRIPTION OF CAPITAL STOCK

General

Our Articles of Incorporation provide that we are authorized to issue, without shareholder action, a total of 30,000,000 shares of common stock, par value $1.00 per share, and 500,000 shares of preferred stock, no par value per share. The preferred stock may be issued in one or more series and with such terms and conditions, at such times and for such consideration as our board of directors may determine. As of June 30, 2024, 15,773,468 shares of common stock were issued and outstanding, and no shares of preferred stock were issued and outstanding.

The following description of the material terms of our capital stock is only a summary. This summary does not purport to be a complete description of the terms and conditions of our capital stock in all respects and is subject to and qualified in its entirety by reference to our Articles of Incorporation and our Bylaws, each of which is

incorporated herein by reference, as well as the IBCA, and any other documents referenced in the summary and from which the summary is derived.

Common Stock

General. Under our Articles of Incorporation, we have the authority to issue 30,000,000 shares of our common stock, par value $1.00 per share. As of June 30, 2024, there were 231,966 shares of our common stock underlying options and restricted stock units that have been awarded or granted pursuant to our equity incentive plans and 539,315 shares of our common stock reserved for future issuance under our equity incentive plans. Our common stock is listed for trading on the Nasdaq Global Select Market under the symbol "MOFG."

Each share of our common stock has the same relative rights and is identical in all respects to every other share of our common stock. Our shares of common stock are neither redeemable nor convertible, and the holders thereof have no preemptive or subscription rights to purchase any of our securities.

Voting Rights. Each outstanding share of our common stock is entitled to one vote on all matters submitted to a vote of shareholders. There is no cumulative voting in the election of directors. The board of directors is classified into three classes, with approximately one-third of the directors up for election each year.

Liquidation Rights. Upon our liquidation, dissolution or winding up, the holders of our common stock are entitled to receive, pro rata, our assets which are legally available for distribution, after payment of all debts and other liabilities and subject to the prior rights of any holders of preferred stock then outstanding.

Dividends Payable on Shares of Common Stock. In general, the holders of outstanding shares of our common stock are entitled to receive dividends out of assets legally available therefor at such times and in such amounts as our board of directors may from time to time determine. The ability of our board of directors to declare and pay dividends on our common stock may be affected by both general corporate law considerations and policies of the Board of Governors of the Federal Reserve (the "Federal Reserve") applicable to bank holding companies. As an Iowa corporation, we are subject to the limitations of Iowa law, which allows us to pay dividends unless, after such dividend: (i) we would not be able to pay our debts as they become due in the usual course of business; or (ii) our total assets would be less than the sum of our total liabilities plus any amount that would be needed, if we were to be dissolved at the time of the dividend payment, to satisfy the preferential rights upon dissolution of our shareholders whose preferential rights are superior to the rights of our shareholders receiving the distribution. As a bank holding company, our ability to declare and pay dividends is also subject to the guidelines of the Federal Reserve regarding capital adequacy and dividends. The Federal Reserve guidelines generally require us to review the effects of the cash payment of dividends on our common stock and other Tier 1 capital instruments in light of our earnings, capital adequacy and financial condition. As a general matter, the Federal Reserve has indicated that the board of directors of a bank holding company should eliminate, defer or significantly reduce the dividends if: (i) the company's net income available to shareholders for the past four quarters, net of dividends previously paid during that period, is not sufficient to fully fund the dividends; (ii) the prospective rate of earnings retention is inconsistent with the company's capital needs and overall current and prospective financial condition; or (iii) the company will not meet, or is in danger of not meeting, its minimum regulatory capital adequacy ratios. The Federal Reserve also possesses enforcement powers over bank holding companies and their nonbank subsidiaries to prevent or remedy actions that represent unsafe or unsound practices or violations of applicable statutes and regulations. Among these powers is the ability to proscribe the payment of dividends by banks and bank holding companies. In addition, under the Basel III regulatory capital reforms (the "Basel III Rule"), institutions that seek the freedom to pay dividends have to maintain 2.5% in Common Equity Tier 1 Capital attributable to the capital conservation buffer.

Most of our revenues available for the payment of dividends derive from amounts paid to us by the Bank. There are various statutory limitations that limit the ability of the Bank to pay dividends to us. The Bank is an Iowa

state-charted bank and is subject to the laws and regulations of the Iowa Division of Banking and to the regulations of the FDIC. If a bank's primary banking regulator determines that the bank is engaged or is about to engage in an unsafe or unsound banking practice, the regulator may require, after notice and hearing, that the bank cease and desist from such practice.

Depending on the financial condition of the bank, an unsafe or unsound practice could include the payment of dividends. In particular, the federal banking agencies have indicated that paying dividends that deplete a bank's capital base to an inadequate level would be an unsafe and unsound banking practice.

Under the Iowa Banking Act, Iowa state-chartered banks, such as the Bank, generally may pay dividends only out of undivided profits. In addition, the Iowa Division of Banking may restrict the declaration or payment of a dividend by an Iowa state-chartered bank.

Furthermore, the payment of dividends by any FDIC-insured institution is affected by the requirement to maintain adequate capital pursuant to applicable capital adequacy guidelines and regulations, and a FDIC-insured institution generally is prohibited from paying any dividends if, following payment thereof, the institution would be undercapitalized. Notwithstanding the availability of funds for dividends, the FDIC and the Iowa Division of Banking may prohibit the payment of any dividends by an insured bank, such as the Bank, if either or both determines such payment would constitute an unsafe or unsound practice. In addition, under the Basel III Rule, institutions that seek the freedom to pay dividends will have to maintain 2.5% in Common Equity Tier 1 Capital attributable to the capital conservation buffer.

Preferred Stock

General. We may issue up to 500,000 shares of preferred stock, no par value per share, from time to time in one or more series. Our board of directors, without further approval of the shareholders, has the authority to fix the dividend rights and terms, conversion rights, voting rights, redemption rights and terms, liquidation preferences, sinking funds and any other rights, preferences, privileges and restrictions applicable to each series of preferred stock. The issuance of preferred stock, while providing flexibility in connection with possible acquisitions and other corporate purposes, could, among other things, adversely affect the voting power of the holders of our common stock.

The applicable prospectus supplement and any other offering materials relating to any series of preferred stock issued under the registration statement of which this prospectus is a part will specify the terms of the series, including:

·	the maximum number of shares in the series and the designation of the series;

·	the terms on which dividends, if any, will be paid;

·	the terms on which the shares of the series may be redeemed, if at all;

·	the liquidation preference, if any;

·	the terms of any retirement or sinking fund for the purchase or redemption of the shares of the series;

·	the terms and conditions, if any, on which the shares of the series will be convertible into, or exchangeable for, shares of any other class or classes of common or preferred stock;

·	the voting rights, if any, of the shares of the series; and

·	any or all other preferences and relative, participating, operational or other special rights or qualifications, limitations or restrictions of the shares of the series.

The description of preferred stock above and the description of the terms of a particular series of preferred stock contained in the applicable prospectus supplement and other offering materials, if any, are not complete. You should refer to the applicable certificate of designations with respect to a series of preferred stock for complete information concerning the terms of that series. A copy of the certificate of designations for each series of preferred stock will be filed with the SEC as an exhibit to the registration statement of which this prospectus is a part or as an exhibit to a filing incorporated by reference in the registration statement.

Anti-Takeover Provisions.

General. Our Articles of Incorporation and Bylaws may have the effect of discouraging, delaying or preventing a change in control or an unsolicited acquisition proposal that a shareholder might consider favorable, including a proposal that might result in the payment of a premium over the market price for the shares held by shareholders. These provisions are summarized in the following paragraphs.

Authorized Shares of Capital Stock. Authorized but unissued shares of our common stock and preferred stock under our Articles of Incorporation could (within the limits imposed by applicable law and Nasdaq Marketplace Rules) be issued in one or more transactions that could make a change of control of us more difficult, and therefore more unlikely. The additional authorized shares could be used to discourage persons from attempting to gain control of us by diluting the voting power of shares then outstanding or increasing the voting power of persons who would support the board of directors in a potential takeover situation, including by preventing or delaying a proposed business combination that is opposed by the board of directors although perceived to be desirable by some shareholders.

Limitations on Right to Call Special Meetings; Shareholder Proposal Notice Requirements. Under our Bylaws, a special meeting of our shareholders may be called only by: (i) the Chairman of our board of directors, our Chief Executive Officer or our President; or (ii) in accordance with Section 490.702 of the IBCA which requires written demand by shareholders owning at least 50% of the total voting power of the outstanding stock entitled to vote on the issue proposed to be considered at the special meeting. Additionally, our Bylaws require that shareholder proposals meet certain advanced notice and minimum informational requirements. These provisions could have the effect of delaying until the next annual shareholders' meeting shareholder actions which are favored by the holders of a majority of our outstanding voting securities.

State Anti-Takeover Laws. The IBCA contains an anti-takeover provision referred to as the "business combinations with interested shareholders" provision. This provision prevents a corporation from engaging in any business combination with an "interested shareholder" (as defined in the IBCA) for a period of three years following the time that the shareholder became an interested shareholder, unless one of the following conditions applies: (i) prior to the time that the shareholder became an interested shareholder, the board of directors of the corporation approved either the business combination or the transaction that resulted in the shareholder becoming an interested shareholder; (ii) upon consummation of the transaction which resulted in the shareholder becoming an interested shareholder, the interested shareholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced; or (iii) at or subsequent to the time the shareholder became an interested shareholder, the business combination is approved by the board of directors and authorized at an annual or special meeting of shareholders by the affirmative vote of at least 66 2/3% of the outstanding voting stock that is not owned by the interested shareholder.

The Bank Holding Company Act of 1956. The ability of a third party to acquire our stock is also limited under applicable U.S. banking laws, including regulatory approval requirements. The Bank Holding Company Act of 1956, as amended (the "BHCA"), requires any "bank holding company" to obtain the approval of the Federal Reserve before acquiring, directly or indirectly, more than 5% of our outstanding common stock. Federal law also prohibits

any person or company from acquiring "control" of an FDIC-insured depository institution or its holding company without prior notice to the appropriate federal bank regulator. "Control" is conclusively presumed to exist upon the acquisition of 25% or more of the outstanding voting securities of a bank or bank holding company, but may arise under certain circumstances between 10% and 24.99% ownership.

DESCRIPTION OF DEBT SECURITIES

General

The debt securities that we may offer using this prospectus consist of notes, debentures or other evidences of indebtedness. Any debt securities that we offer and sell will be our direct obligations. Debt securities may be issued in one or more series. All debt securities of any one series need not be issued at the same time, and unless otherwise provided, a series of debt securities may be reopened, without the consent of the holders of outstanding debt securities, for issuance of additional debt securities of that series or to establish additional terms of that series of debt securities (with such additional terms applicable only to unissued or additional debt securities of that series). As required by the Trust Indenture Act of 1939, as amended (the "Trust Indenture Act"), for all debt securities that are publicly offered, our debt securities will be governed by a document called an indenture. The form of indenture is subject to any amendments or supplements that we may enter into with the trustee(s) setting forth the specific terms and conditions of the debt securities being issued. The indenture is filed as an exhibit to the registration statement of which this prospectus forms a part. The material terms of the indenture are summarized below, and we refer you to the indenture for a detailed description of these material terms. Additional or different provisions that are applicable to a particular series of debt securities will, if material, be described in a prospectus supplement relating to the offering of debt securities of that series. These provisions may include, among other things and to the extent applicable, the following:

·

the rate or rates, which may be fixed or variable, at which the debt securities will bear interest, if any, the date or dates from which any such interest will accrue, the interest payment dates on which we will pay any such interest, the basis upon which interest will be calculated if other than that of a 360-day year consisting of twelve 30-day months, and, in the case of registered securities, the record dates for the determination of holders to whom interest is payable;

·	the place or places where the principal of, and any premium or interest on, the debt securities will be payable and, if applicable, where the debt securities may be surrendered for conversion or exchange;

·

whether we may, at our option, redeem, repurchase or repay the debt securities, and if so, the price or prices at which, the period or periods within which, and the terms and conditions upon which, we may redeem, repurchase or repay the debt securities, in whole or in part, pursuant to any sinking fund or otherwise;

·	if other than 100% of the aggregate principal amount thereof, the portion of the principal amount of the debt securities which will be payable upon declaration of acceleration of the maturity date thereof or provable in bankruptcy, or, if applicable, which is convertible or exchangeable;

·

any obligation we may have to redeem, purchase or repay the debt securities pursuant to any sinking fund or analogous provisions or at the option of a holder of debt securities, and the price or prices at which, the currency in which and the period or periods within which, and the other terms and conditions upon which, the debt securities will be redeemed, purchased or repaid, in whole or in part, pursuant to any such obligation, and any provision for the remarketing of the debt securities;

·

whether the debt securities will be issued in the form of certificated debt securities, and if so, the form of the debt securities (or forms thereof if unregistered and registered securities are issuable in that series), including the legends required by law or as we deem necessary or appropriate, the form of any coupons or temporary global security which may be issued and the forms of any other certificates which may be required under the indenture or which we may require in connection with the offering, sale, delivery or exchange of the debt securities;

·

whether, under what circumstances and the currency in which, we will pay additional amounts on the debt securities to any holder of the debt securities who is not a U.S. person in respect of any tax, assessment or governmental charge and, if so, whether we will have the option to redeem such debt securities rather than pay such additional amounts (and the terms of any such option);

·

whether the debt securities, in whole or specified parts, will be defeasible, and, if the securities may be defeased, in whole or in specified part, any provisions to permit a pledge of obligations other than certain government obligations to satisfy the requirements of the indenture regarding defeasance of securities and, if other than by resolution of our board of directors, the manner in which any election to defease the debt securities will be evidenced;

·	whether the debt securities will be secured by any property, assets or other collateral and, if so, a general description of the collateral and the terms of any related security, pledge or other agreements;

·	any other material terms or conditions upon which the debt securities will be issued.

Unless otherwise indicated in the applicable prospectus supplement, we will issue debt securities in fully registered form without coupons and in denominations of $1,000 and in integral multiples of $1,000, and interest will be computed on the basis of a 360-day year of twelve 30-day months. If any interest payment date or the maturity date falls on a day that is not a business day, then the payment will be made on the next business day without additional interest and with the same effect as if it were made on the originally scheduled date.

Unless otherwise indicated in the applicable prospectus supplement, the trustee will act as paying agent and registrar for the debt securities under the indenture. We may also act as paying agent under the indenture.

The applicable prospectus supplement will contain a description of U.S. federal income tax consequences relating to the debt securities, to the extent applicable.

Covenants

The applicable prospectus supplement will describe any covenants, such as restrictive covenants restricting us or any of our subsidiaries from incurring, issuing, assuming or guaranteeing any indebtedness, restricting us or any of our subsidiaries from paying dividends or acquiring any of our or its capital stock or requiring the maintenance of any asset ratio or the creation or maintenance of any reserves, or restricting the incurrence of additional debt or the issuance of additional securities.

Consolidation, Merger and Transfer of Assets

Unless we indicate otherwise in the applicable prospectus supplement, the indenture will permit a consolidation or merger between us and another entity and/or the sale, conveyance or lease by us of all or substantially all of our property and assets; provided, however, that:

·

we are the surviving or continuing entity, or the resulting or acquiring entity, if other than us, is organized and existing under the laws of a U.S. jurisdiction and assumes, pursuant to a supplemental indenture, all of our responsibilities and liabilities under the indenture, including the payment of all amounts due on the debt securities and performance of the covenants in the indenture;

·	immediately after the transaction, and giving effect to the transaction, no event of default under the indenture exists; and

·

we have delivered to the trustee an officers' certificate stating that the transaction and, if a supplemental indenture is required in connection with the transaction, the supplemental indenture, comply with the indenture and that all conditions precedent to the transaction contained in the indenture have been satisfied.

If we consolidate or merge with or into any other entity, or sell or lease all or substantially all of our assets in compliance with the terms and conditions of the indenture, the resulting or acquiring entity will be substituted for us in the indenture and the debt securities with the same effect as if it had been an original party to the indenture and the debt securities. As a result, such successor entity may exercise our rights and powers under the indenture and the debt securities, in our name, and, except in the case of a lease, we will be released from all our liabilities and obligations under the indenture and under the debt securities.

Notwithstanding the foregoing, we may transfer all of our property and assets to another entity if, immediately after giving effect to the transfer, such entity is our wholly-owned subsidiary. The term "wholly-owned subsidiary" means any subsidiary in which we and/or our other wholly-owned subsidiaries own all of the outstanding capital stock.

Modification and Waiver

Unless we indicate otherwise in the applicable prospectus supplement, under the indenture, some of our rights and obligations and some of the rights of the holders of the debt securities may be modified or amended with the consent of the holders of not less than a majority in aggregate principal amount of the outstanding debt securities affected by the modification or amendment. However, the following modifications and amendments will not be effective against any holder without its consent:

·	a change in the stated maturity date of any payment of principal or interest;

·	a reduction in the principal amount of, or interest on, any debt securities;

·	an alteration or impairment of any right to convert at the rate or upon the terms provided in the indenture;

·	a change in the currency in which any payment on the debt securities is payable;

·	an impairment of a holder's right to sue us for the enforcement of payments due on the debt securities; or

·	a reduction in the percentage of outstanding debt securities required to consent to a modification or amendment of the indenture or required to consent to a waiver of compliance with certain provisions of the indenture or certain defaults under the indenture.

Under the indenture, the holders of not less than a majority in aggregate principal amount of the outstanding debt securities may, on behalf of all holders of the debt securities:

·	waive compliance by us with certain restrictive provisions of the indenture; and

·	waive any past default under the indenture in accordance with the applicable provisions of the indenture, except a default in the payment of the principal of, or interest on, any series of debt securities.

Finally, we and the indenture trustee may, from time to time, amend the indenture without the consent of holders of the debt securities for certain purposes, including but not limited to the following:

·	to evidence the succession of another entity to us or successive successions and the assumption by such entity of our covenants, agreements and obligations under the indenture;

·	to add additional events of default for the protection of the holders of debt securities;

·	to add covenants for the protection of the holders of debt securities; and

·	to make certain other administrative modifications which do not materially and adversely affect the interests of the holders of debt securities.

Events of Default

Unless we indicate otherwise in the applicable prospectus supplement, "event of default" under the indenture will mean, with respect to any series of debt securities, any of the following:

·	failure to pay interest on any debt security for 30 days after the payment is due;

·	failure to pay the principal of any debt security when due, either at maturity, upon redemption, by declaration or otherwise;

·	failure on our part to observe or perform any other covenant or agreement in the indenture that applies to the debt securities for 90 days after we have received written notice of the failure to perform in the manner specified in the indenture; and

·	certain events of bankruptcy, insolvency or reorganization.

If an event of default occurs and continues, the trustee or the holders of not less than 25% in aggregate principal amount of the outstanding debt securities of such series may declare the entire principal of all the debt securities to be due and payable immediately, except that, if the event of default is caused by certain events of bankruptcy, insolvency or reorganization, the entire principal of all of the debt securities of such series will become due and payable immediately without any act on the part of the trustee or holders of the debt securities. If such a declaration occurs, the holders of a majority of the aggregate principal amount of the outstanding debt securities of such series can, subject to conditions, rescind the declaration.

The indenture requires us to furnish to the trustee, not less often than annually, a certificate from our principal executive officer, principal financial officer or principal accounting officer, as the case may be, as to such officer's knowledge of our compliance with all conditions and covenants under the indenture. The trustee may withhold notice to the holders of debt securities of any default, except defaults in the payment of principal of, or interest on, any debt securities if the trustee in good faith determines that the withholding of notice is in the best interests of the holders. For purposes of this paragraph, "default" means any event which is, or after notice or lapse of time or both would become, an event of default under the indenture.

The trustee is not obligated to exercise any of its rights or powers under the indenture at the request, order or direction of any holders of debt securities, unless the holders offer the trustee satisfactory security or indemnity. If satisfactory security or indemnity is provided, then, subject to other rights of the trustee, the holders of a majority in aggregate principal amount of the outstanding debt securities may direct the time, method and place of:

·	conducting any proceeding for any remedy available to the trustee; or

·	exercising any trust or power conferred upon the trustee.

The holder of a debt security will have the right to begin any proceeding with respect to the indenture or for any remedy only if:

·	the holder has previously given the trustee written notice of a continuing event of default;

·	the holders of not less than a majority in aggregate principal amount of the outstanding debt securities have made a written request of, and offered reasonable indemnity to, the trustee to begin such proceeding;

·	the trustee has not started such proceeding within 60 days after receiving the request; and

·	no direction inconsistent with such written request has been given to the trustee under the indenture.

However, the holder of any debt security will have an absolute right to receive payment of principal of, and interest on, the debt security when due and to institute suit to enforce payment.

Satisfaction and Discharge; Defeasance

Satisfaction and Discharge of Indenture. Unless otherwise indicated in the applicable prospectus supplement, if at any time:

·	we have paid or caused to be paid the principal of and interest on all the debt securities of any series, except for debt securities which have been destroyed, lost or stolen and which have been replaced or paid in accordance with the indenture, as and when the same has become due and payable;

·	we have delivered to the trustee for cancellation all debt securities of any series theretofore authenticated, except for debt securities of such series which have been destroyed, lost or stolen and which have been replaced or paid as provided in the indenture; or

·

all the debt securities of such series not theretofore delivered to the trustee for cancellation have become due and payable, or are by their terms are to become due and payable within one year or are to be called for redemption within one year, and we have deposited with the trustee, in trust, sufficient money or government obligations, or a combination thereof, to pay the principal, any interest and any other sums due on the debt

securities, on the dates the payments are due or become due under the indenture and the terms of the debt securities;

then the indenture shall cease to be of further effect with respect to the debt securities of such series, except for (i) rights of registration of transfer and exchange, and our right of optional redemption, (ii) substitution of mutilated, defaced, destroyed, lost or stolen debt securities, (iii) rights of holders to receive payments of principal thereof and interest thereon upon the original stated due dates therefor (but not upon acceleration) and remaining rights of the holders to receive mandatory sinking fund payments, if any, (iv) the rights, obligations and immunities of the trustee under the indenture, and (v) the rights of the holders of such series of debt securities as beneficiaries thereof with respect to the property so deposited with the trustee payable to all or any of them.

Defeasance and Covenant Defeasance. Unless otherwise indicated in the applicable prospectus supplement, we may elect with respect to any debt securities of any series either:

·	to defease and be discharged from all of our obligations with respect to such debt securities ("defeasance"), with certain exceptions described below; or

·

to be released from our obligations with respect to such debt securities under such covenants as may be specified in the applicable prospectus supplement, and any omission to comply with those obligations will not constitute a default or an event of default with respect to such debt securities ("covenant defeasance").

We must comply with the following conditions before the defeasance or covenant defeasance can be effected:

·

we must irrevocably deposit with the indenture trustee or other qualifying trustee, under the terms of an irrevocable trust agreement in form and substance satisfactory to the trustee, trust funds in trust solely for the benefit of the holders of such debt securities, sufficient money or government obligations, or a combination thereof, to pay the principal, any interest and any other sums on the due dates for those payments; and

·

we must deliver to the trustee an opinion of counsel to the effect that the holders of such debt securities will not recognize income, gain or loss for federal income tax purposes as a result of such defeasance or covenant defeasance, as the case may be, to be effected with respect to such debt securities and will be subject to federal income tax on the same amount, in the same manner and at the same times as would be the case if such defeasance or covenant defeasance, as the case may be, had not occurred.

In connection with defeasance, any irrevocable trust agreement contemplated by the indenture must include, among other things, provision for: (i) payment of the principal of and interest on such debt securities, if any, appertaining thereto when due (by redemption, sinking fund payments or otherwise); (ii) the payment of the expenses of the trustee incurred or to be incurred in connection with carrying out such trust provisions; (iii) rights of registration, transfer, substitution and exchange of such debt securities in accordance with the terms stated in the indenture; and (iv) continuation of the rights, obligations and immunities of the trustee as against the holders of such debt securities as stated in the indenture.

The accompanying prospectus supplement may further describe any provisions permitting or restricting defeasance or covenant defeasance with respect to the debt securities of a particular series.

Global Securities

Unless otherwise indicated in the applicable prospectus supplement, each debt security offered by this prospectus will be issued in the form of one or more global debt securities representing all or part of that series of debt securities. This means that we will not issue certificates for that series of debt securities to the holders. Instead, a

global debt security representing that series will be deposited with, or on behalf of, a securities depositary and registered in the name of the depositary or a nominee of the depositary. Any such depositary must be a clearing agency registered under the Securities Exchange Act of 1934, as amended (the "Exchange Act"). We will describe the specific terms of the depositary arrangement with respect to a series of debt securities to be represented by a global security in the applicable prospectus supplement.

Notices

We will give notices to holders of the debt securities by mail at the addresses listed in the security register. In the case of notice in respect of unregistered securities or coupon securities, we may give notice by publication in a newspaper of general circulation in New York, New York.

Governing Law

The indenture and the debt securities will be governed by, and construed in accordance with, the laws of the State of New York, except to the extent the Trust Indenture Act is applicable.

Regarding the Trustee

General. We will enter into the indenture with a trustee that is qualified to act under the Trust Indenture Act and with any other trustees chosen by us and appointed in a supplemental indenture for a particular series of debt securities.

Resignation or Removal of Trustee. If the trustee has or acquires a conflicting interest within the meaning of the Trust Indenture Act, the trustee must either eliminate its conflicting interest or resign, to the extent and in the manner provided by, and subject to the provisions of, the Trust Indenture Act and the indenture. Any resignation will require the appointment of a successor trustee under the indenture in accordance with the terms and conditions of the indenture.

The trustee may resign or be removed by us with respect to one or more series of debt securities and a successor trustee may be appointed to act with respect to any such series. The holders of a majority in aggregate principal amount of the debt securities of any series may remove the trustee with respect to the debt securities of such series.

Annual Trustee Report to Holders of Debt Securities. The trustee will be required to submit certain reports to the holders of the debt securities regarding, among other things, the trustee's eligibility to serve as such, the priority of the trustee's claims regarding advances made by it, and any action taken by the trustee materially affecting the debt securities.

Certificates and Opinions to Be Furnished to Trustee. The indenture provides that, in addition to other certificates or opinions specifically required by other provisions of the indenture, every application by us for action by the trustee must be accompanied by a certificate from one or more of our officers and an opinion of counsel (who may be our counsel) stating that, in the opinion of the signers, all conditions precedent to such action have been complied with by us.

Certain Relationships in the Ordinary Course. From time to time, we may maintain deposit accounts and conduct other banking transactions with the trustee to be appointed under the indenture or its affiliates in the ordinary course of business.

DESCRIPTION OF WARRANTS

We may issue warrants for the purchase of debt securities, preferred stock, common stock, other securities of the Company or any combination of the foregoing. Warrants may be issued alone or together with securities offered by any prospectus supplement and may be attached to, or separate from, those securities. The particular terms of any warrants will be described more specifically in the prospectus supplement relating to such warrants.

The prospectus supplement relating to any warrants we are offering will include specific terms relating to the offering. We will file the form of any warrant agreement with the SEC, and you should read the warrant agreement for provisions that may be important to you. The prospectus supplement will include some or all of the following information:

·	the title and specific designation of the warrants;

·	the aggregate number of warrants offered;

·	the amount of warrants outstanding, if any;

·	the price or prices at which the warrants will be issued;

·	the designation, number and terms of the securities purchasable upon exercise of the warrants, and procedures that will result in the adjustment of those numbers;

·	the exercise price or prices of the warrants;

·	the dates or periods during which the warrants are exercisable;

·	the designation and terms of any securities with which the warrants are issued;

·	if the warrants are issued as a unit with another security, the date, if any, on and after which the warrants and the other security will be separately transferable;

·	if the exercise price is not payable in U.S. dollars, the foreign currency, currency unit or composite currency in which the exercise price is denominated;

·	any minimum or maximum number of warrants that may be exercised at any one time;

·	the anti-dilution, redemption or call provisions of the warrants, if any;

DESCRIPTION OF DEPOSITARY SHARES

This following is a summary of the general terms of the deposit agreement to goveany depositary shares we may offer representing fractional interests in shares of our preferred stock, the depositary shares themselves and the related depositary receipts. This summary does not purport to be complete in all respects and is subject to and qualified entirely by reference to the relevant deposit agreement and depositary receipt with respect to the depositary shares relating to any particular series of preferred stock. A copy of the deposit agreement and form of depositary receipt relating to any depositary shares we issue will be filed with the SEC as an exhibit to the registration statement of which this prospectus is a part or as an exhibit to a filing incorporated by reference in the registration statement. The specific terms of any depositary shares we may offer will be described in the applicable prospectus supplement. If so described in the applicable prospectus supplement, the terms of that series of depositary shares may differ from the general description of terms presented below.

General

We may offer fractional interests in shares of our preferred stock, rather than full shares of preferred stock, most likely in the event that our then authorized but yet undesignated shares of preferred stock are not sufficient to offer full shares of preferred stock. If we do, we will provide for the issuance by a depositary to the public of receipts for depositary shares, each of which will represent a fractional interest in a share of a particular series of preferred stock.

The shares of any series of preferred stock underlying the depositary shares will be deposited under a separate deposit agreement between us and a bank or trust company having its principal office in the United States and having a combined capital and surplus of such amount as may be set forth in the applicable prospectus supplement, which we refer to in this section as the depositary. We will name the depositary in the applicable prospectus supplement. Subject to the terms of the deposit agreement, each owner of a depositary share will have a fractional interest in all the rights and preferences of the preferred stock underlying the depositary share. Those rights include any dividend, voting, redemption, conversion and liquidation rights.

The depositary shares will be evidenced by depositary receipts issued under the deposit agreement. Purchasers of fractional interests in shares of the related series of preferred stock will receive depositary receipts as described in the applicable prospectus supplement.

Unless we specify otherwise in the applicable prospectus supplement, purchasers will not be entitled to receive the whole shares of preferred stock underlying the depositary shares.

Dividend Rights

The depositary will distribute all cash dividends or other cash distributions in respect of the preferred stock underlying the depositary shares to each record holder of depositary shares based on the number of the depositary shares owned by that holder on the relevant record date. The depositary will distribute only that amount which can be distributed without attributing to any holder of depositary shares a fraction of one cent, and any balance not so distributed will be added to and treated as part of the next sum received by the depositary for distribution to record holders of depositary shares.

If there is a distribution other than in cash, the depositary will distribute property to the entitled record holders of depositary shares, unless the depositary determines that it is not feasible to make that distribution. In that case the depositary may, with our approval, adopt the method it deems equitable and practicable for making that distribution, including any sale of property and distribution of the net proceeds from this sale to the applicable holders.

The deposit agreement will also contain provisions relating to how any subscription or similar rights offered by us to holders of the preferred stock will be made available to the holders of depositary shares.

Voting Rights

When the depositary receives notice of any meeting at which the holders of the preferred stock may vote, the depositary will mail information about the meeting contained in the notice, and any accompanying proxy materials, to the record holders of the depositary shares relating to the preferred stock. Each record holder of such depositary shares on the record date, which will be the same date as the record date for the preferred stock, will be entitled to instruct the depositary as to how the preferred stock underlying the holder's depositary shares should be voted.

Conversion or Exchange Rights

If any series of preferred stock underlying the depositary shares is subject to conversion or exchange, the applicable prospectus supplement will describe the rights or obligations of each record holder of depositary receipts to convert or exchange the depositary shares.

Redemption

If the series of the preferred stock underlying the depositary shares is subject to redemption, all or a part of the depositary shares will be redeemed from the redemption proceeds of that series of the preferred stock held by the depositary. The redemption price per depositary share will bear the same relationship to the redemption price per share of preferred stock that the depositary share bears to the underlying preferred stock. Whenever we redeem preferred stock held by the depositary, the depositary will redeem, as of the same redemption date, the number of depositary shares representing the preferred stock redeemed. If less than all the depositary shares are to be redeemed, the depositary shares to be redeemed will be selected by lot or pro rata as determined by the depositary.

After the date fixed for redemption, the depositary shares called for redemption will no longer be outstanding. When the depositary shares are no longer outstanding, all rights of the holders will cease, except the right to receive money or other property that the holders of the depositary shares were entitled to receive upon the redemption. Payments will be made when holders surrender their depositary receipts to the depositary.

Taxation

Owners of depositary shares will be treated for U.S. federal income tax purposes as if they were owners of the preferred stock represented by the depositary shares. If necessary, the applicable prospectus supplement will provide a description of U.S. federal income tax consequences relating to the purchase and ownership of the depositary shares and the preferred stock represented by the depositary shares.

Amendment and Termination of the Deposit Agreement

The form of depositary receipt evidencing the depositary shares and any provision of the deposit agreement may be amended by agreement between us and the depositary at any time. However, certain amendments as specified in the applicable prospectus supplement will not be effective unless approved by the record holders of at least a majority of the depositary shares then outstanding. A deposit agreement may be terminated by us or the depositary only if:

·	all outstanding depositary shares relating to the deposit agreement have been redeemed; or

·	there has been a final distribution on the preferred stock of the relevant series in connection with our liquidation, dissolution or winding up of our business and the distribution has been distributed to the holders of the related depositary shares.

Charges of Depositary

We will pay all transfer and other taxes and governmental charges arising solely from the existence of the depositary arrangements. We will pay associated charges of the depositary for the initial deposit of the preferred stock and any redemption of the preferred stock. Holders of depositary shares will pay transfer and other taxes and governmental charges and any other charges that are stated to be their responsibility in the deposit agreement.

Resignation and Removal of Depositary

The depositary may resign at any time by delivering notice to us. We may also remove the depositary at any time. Resignations or removals will take effect when a successor depositary is appointed and it accepts the appointment.

DESCRIPTION OF SUBSCRIPTION RIGHTS

The following is a summary of the general terms of the subscription rights to purchase common stock or other securities that we may offer to shareholders using this prospectus. This summary does not purport to be complete in all respects and is subject to and qualified entirely by reference to the applicable forms of subscription agent agreement and subscription certificate for a full understanding of all terms of any series of subscription rights. The forms of the subscription agent agreement and the subscription certificate will be filed with the SEC as an exhibit to the registration statement of which this prospectus is a part or as an exhibit to a filing incorporated by reference in the registration statement. See "Where You Can Find Additional Information" for information on how to obtain copies.

Subscription rights may be issued independently or together with any other security and may or may not be transferable. As part of any subscription rights offering, we may enter into a standby underwriting or other arrangement under which the underwriters or any other person would purchase any securities that are not purchased in such subscription rights offering. If we issue subscription rights, they will be governed by a separate subscription agent agreement that we will sign with a bank or trust company, as rights agent, that will be named in the applicable prospectus supplement. The rights agent will act solely as our agent and will not assume any obligation to any holders of subscription rights certificates or beneficial owners of subscription rights.

The prospectus supplement relating to any subscription rights we offer will describe the specific terms of the offering and the subscription rights, including the record date for shareholders entitled to the subscription rights distribution, the number of subscription rights issued and the number of shares of common stock or other securities that may be purchased upon exercise of the subscription rights, the exercise price of the subscription rights, the date on which the subscription rights will become effective and the date on which the subscription rights will expire, and any material U.S. federal income tax considerations.

In general, a subscription right entitles the holder to purchase for cash a specific number of shares of common stock or other securities at a specified exercise price. The rights are normally issued to shareholders as of a specific record date, may be exercised only for a limited period of time and become void following the expiration of such period. If we determine to issue subscription rights, we will accompany this prospectus with a prospectus supplement that will describe, among other things:

·	the record date for shareholders entitled to receive the subscription rights;

·	the number of shares of common stock or other securities that may be purchased upon exercise of each subscription right;

·	the exercise price of the subscription rights;

·	whether the subscription rights are transferable;

·	the period during which the subscription rights may be exercised and when they will expire;

·	the steps required to exercise the subscription rights;

·	whether the subscription rights include "oversubscription rights" so that the holder may purchase more securities if other holders do not purchase their full allotments; and

·	whether we intend to sell the shares of common stock or other securities that are not purchased in the rights offering to an underwriter or other purchaser under a contractual "standby" commitment or other arrangement.

If fewer than all of the subscription rights issued in any rights offering are exercised, we may offer any unsubscribed securities directly to persons other than shareholders, to or through agents, underwriters or dealers or through a combination of such methods, including pursuant to standby arrangements, as described in the applicable prospectus supplement. After the close of business on the expiration date of a subscription rights offering, all unexercised subscription rights will become void.

DESCRIPTION OF STOCK PURCHASE CONTRACTS AND STOCK PURCHASE UNITS

We may issue stock purchase contracts, including contracts obligating holders to purchase from us, and us to sell to the holders, a specified number of shares of our common stock or preferred stock at a future date or dates, which we refer to in this prospectus as "Stock Purchase Contracts." The price per share, and number of shares, of our common stock or preferred stock may be fixed at the time the Stock Purchase Contracts are issued or may be determined by reference to a specific formula set forth in the Stock Purchase Contracts. The Stock Purchase Contracts may be issued separately or as a part of units consisting of a Stock Purchase Contract and our debt securities or debt obligations of third parties, including Treasury securities, securing the holders' obligations to purchase the shares of our common stock under the Stock Purchase Contracts, which we refer to in this prospectus as "Stock Purchase Units." The Stock Purchase Contracts may require holders to secure their obligations thereunder in a specified manner. The Stock Purchase Contracts also may require us to make periodic payments to the holders of the Stock Purchase Units or vice-versa and such payments may be unsecured or prefunded on some basis.

The applicable prospectus supplement will describe the terms of any Stock Purchase Contracts or Stock Purchase Units. The description in the prospectus supplement will not necessarily be complete, and reference will be made to the Stock Purchase Contracts, and, if applicable, collateral or depositary arrangements, relating to the Stock Purchase Contracts or Stock Purchase Units. Material U.S. federal income tax considerations applicable to the Stock Purchase Units and the Stock Purchase Contracts will also be discussed in the applicable prospectus supplement.

DESCRIPTION OF UNITS

As specified in the applicable prospectus supplement, we may issue units consisting of one or more debt securities, shares of common stock, shares of preferred stock, depositary shares, warrants or other securities, or any combination of such securities, including guarantees of any securities.

A prospectus supplement and any other offering materials relating to any units issued under the registration statement containing this prospectus will specify the terms of the units, including:

·	the terms of the units and of any of the debt securities, common stock, preferred stock, depositary shares, warrants and guarantees comprising the units, including whether and under what circumstances the securities comprising the units may be traded separately;

·	a description of the terms of any unit agreement governing the units; and

·	a description of the provisions for the payment, settlement, transfer or exchange of the units.

PLAN OF DISTRIBUTION

We may sell the securities covered by this prospectus from time to time at market prices prevailing at the time of sale, at prices related to such prevailing market prices at the time of sale, at negotiated prices or at fixed prices, which may change from time to time. We may sell the securities directly to one or more purchasers, through agents, to dealers, through underwriters, brokers or dealers, or through a combination of any of these sales methods or through any other method permitted by law (including in "at the market" equity offerings as defined in Rule 415 of the Securities Act). We reserve the right to accept or reject, in whole or in part, any proposed purchase of securities, whether the purchase is to be made directly or through agents.

Each time that we use this prospectus to sell our securities, we will also provide a prospectus supplement, if required, that contains the specific terms of the offering, including:

·	the name or names of the underwriters, dealers or agents, if any, and the types and amounts of securities underwritten or purchased by each of them;

·	the public offering price of the securities and the proceeds we will receive from the sale;

·	any over-allotment options under which underwriters may purchase additional securities from us;

·	any agency fees or underwriting discounts or other items constituting agents' or underwriters' compensation;

·	any discounts, commissions or concessions allowed or reallowed or paid to dealers; and

·	any securities exchange or market on which the securities may be listed.

Only underwriters that we have named in a prospectus supplement will be underwriters of the securities offered by that prospectus supplement.

If underwriters are used in the sale, they will acquire the securities for their own account and may resell the securities from time to time in one or more transactions at a fixed public offering price or at varying prices determined at the time of sale. The obligations of the underwriters to purchase the securities will be subject to the conditions set forth in the applicable underwriting agreement. We may offer the securities to the public through underwriting syndicates represented by managing underwriters or by underwriters without a syndicate. Subject to certain conditions, the underwriters will be obligated to purchase all of the securities offered by the prospectus supplement, other than securities covered by any over-allotment option. Any public offering price and any discounts or concessions allowed or reallowed or paid to dealers may change from time to time. We may use underwriters with whom we have a material relationship. We will describe any such material relationship in the prospectus supplement, naming the underwriter and the nature of any such relationship.

We may sell securities directly or through agents we designate from time to time. We will name any agent involved in the offering and sale of securities and we will describe any commissions we will pay the agent in the prospectus supplement. Unless the prospectus supplement states otherwise, our agent will act on a best-efforts basis for the period of its appointment.

We may authorize agents or underwriters to solicit offers by certain types of institutional investors to purchase securities from us at the public offering price set forth in the prospectus supplement pursuant to delayed delivery contracts providing for payment and delivery on a specified date in the future. We will describe the conditions to these contracts and the commissions we must pay for solicitation of these contracts in the applicable prospectus supplement.

We may provide agents and underwriters with indemnification against civil liabilities, including liabilities under the Securities Act, or contribution with respect to payments that the agents or underwriters may make with respect to these liabilities. Agents and underwriters may engage in transactions with, or perform services for, us in the ordinary course of business.

All securities we may offer, other than common stock or other outstanding securities, will be new issues of securities with no established trading market. Any underwriters may make a market in these securities, but will not be obligated to do so and may discontinue any market making at any time without notice. We cannot guarantee the liquidity of the trading markets for any securities.

Any underwriter may engage in over-allotment, stabilizing transactions, short-covering transactions and penalty bids in accordance with Regulation M under the Exchange Act. Over-allotment involves sales in excess of the offering size, which create a short position. Stabilizing transactions permit bids to purchase the underlying security so long as the stabilizing bids do not exceed a specified maximum price. Syndicate-covering or other short-covering transactions involve purchases of the securities, either through exercise of the over-allotment option or in the open market after the distribution is completed, to cover short positions. Penalty bids permit the underwriters to reclaim a selling concession from a dealer when the securities originally sold by the dealer are purchased in a stabilizing or covering transaction to cover short positions. Those activities may cause the price of the securities to be higher than it would otherwise be. If commenced, the underwriters may discontinue any of the activities at any time.

Under the securities laws of some states, to the extent applicable, the securities may be sold in such states only through registered or licensed brokers or dealers. In addition, if our common stock is no longer listed on the Nasdaq Global Select Market or another national securities exchange, in some states the securities may not be sold unless such securities have been registered or qualified for sale in such state or an exemption from registration or qualification is available and is complied with.

LEGAL MATTERS

Certain legal matters in connection with any offering of securities made by this prospectus will be passed upon for us by our counsel, Barack Ferrazzano Kirschbaum & Nagelberg LLP of Chicago, Illinois. If the securities are being distributed in an underwritten offering, certain legal matters will be passed upon for the underwriters by counsel identified in the related prospectus supplement.
