MERGER PROPOSED — YOUR VOTE IS VERY IMPORTANT

To the Shareholders of Bremer Financial Corporation:

On November 25, 2024, Old National Bancorp (“Old National”), Bremer Financial Corporation (“Bremer”), and ONB Merger Sub, Inc. (“ONB Merger Sub”), a wholly-owned subsidiary of Old National, entered into an Agreement and Plan of Merger (“merger agreement”) that provides for the acquisition of Bremer and its wholly-owned banking subsidiary, Bremer Bank, a national banking association, by Old National.

Under the merger agreement, ONB Merger Sub will first merge with and into Bremer (the “first step merger”), with Bremer as the surviving corporation in the first step merger as a wholly-owned subsidiary of Old National. Immediately following the first step merger, and as part of a single, integrated transaction, Bremer will then merge with and into Old National (the “second step merger” and together with the first step merger, the “mergers”), with Old National as the surviving corporation in the second step merger. Immediately following the second step merger, or at a later time as determined by Old National, Bremer Bank will merge with and into Old National’s wholly-owned banking subsidiary, Old National Bank, a national banking association, with Old National Bank as the surviving bank (the “bank merger”).

Under the terms and subject to the conditions set forth in the merger agreement, Bremer shareholders will receive (i) cash and (ii) Old National common stock for each of their shares of Bremer Class A common stock and Bremer Class B common stock (together, the “Bremer common stock”). At the effective time of the first step merger, each outstanding share of Bremer common stock (except for dissenting shares, shares of treasury stock or shares owned by Bremer, Old National or ONB Merger Sub, in each case other than shares held in trust accounts, managed accounts, mutual funds and the like, or otherwise held in a fiduciary or agency capacity that are beneficially owned by third parties, or held, directly or indirectly, as a result of debts previously contracted) will be converted into the right to receive (i) $26.22 in cash without interest and (ii) 4.182 shares of Old National common stock. No fractional shares of Old National common stock will be issued in the mergers, and holders of Bremer common stock will be entitled to receive cash in lieu of fractional shares.

Because the merger consideration is comprised of a fixed amount of cash consideration plus a fixed amount of shares of Old National common stock for each share of Bremer common stock, the market value of the merger consideration will fluctuate with the market price of Old National common stock and will not be known at the time Bremer shareholders vote on the merger agreement. Based on the closing stock price of Old National common stock on the NASDAQ Stock Exchange, as reported by The Wall Street Journal, of $23.58 as of January 28, 2025, the value of the per share merger consideration payable to holders of Bremer common stock was approximately $124.83 as of such date. We suggest that you obtain a current market quotation for Old National common stock, which is currently traded on the NASDAQ Stock Exchange under the trading symbol “ONB”.

The mergers cannot be completed unless the merger agreement is approved and adopted by the affirmative vote of a majority of the voting power of all shares of Bremer common stock entitled to vote thereon. The closing of the mergers is also subject to the receipt of approvals of the Board of Governors of the Federal Reserve System and the Office of the Comptroller of the Currency, and the satisfaction of the other conditions specified in the merger agreement.

The merger agreement will be voted on at a special meeting of Bremer shareholders, which will be held virtually via the Internet on Friday, March 7, 2025, at 8:00 a.m. Central Time. Holders of Bremer common stock as of the close of business on January 24, 2025, the record date for the meeting, are entitled to notice of, and to vote at, the special meeting to approve and adopt the merger agreement as described in this proxy statement/prospectus. Bremer shareholders as of the record date will also be asked to approve an adjournment of the special meeting, if necessary or appropriate, as described in this proxy statement/prospectus.

The trustees of the Otto Bremer Trust have entered into a trustee voting agreement with Old National, and each of the directors of Bremer (other than the trustees of the Otto Bremer Trust, who have separately entered into the trustee voting agreement) has entered into a director voting agreement with Old National. In accordance with these voting agreements, the trustees and directors have agreed to vote “FOR” the approval and adoption of the merger agreement, subject to the terms of the trustee voting agreement and director voting agreements, as applicable. As of the record date for the Bremer special meeting, the Otto Bremer Trust and directors collectively and beneficially owned 86.20% of the outstanding shares of Bremer common stock. Additional information regarding the voting process for the Bremer special meeting is included in this proxy statement/prospectus.

The Bremer board of directors has unanimously determined that the merger agreement and the transactions contemplated by the merger agreement, including the mergers, are advisable and in the best interests of Bremer and its shareholders, has unanimously approved and adopted the execution, delivery and performance by Bremer of the merger agreement and the consummation of the transactions contemplated thereby, including the mergers, and unanimously recommends that Bremer shareholders vote “FOR” the proposal to approve and adopt the merger agreement and “FOR” the proposal to adjourn the special meeting, if necessary or appropriate.

TABLE OF CONTENTS

CERTAIN QUESTIONS AND ANSWERS ABOUT THE MERGERS AND THE SPECIAL MEETING

The following are questions that you may have about the mergers and the Bremer special meeting, and brief answers to those questions. You are urged to read carefully the remainder of this proxy statement/ prospectus because the information in this section does not provide all of the information that might be important to you with respect to the mergers or the Bremer special meeting. Additional important information is also contained in the documents attached to or incorporated by reference into this proxy statement/prospectus. See “Where You Can Find More Information” for more details.

What are the mergers?

Old National Bancorp (“Old National”), Bremer Financial Corporation (“Bremer”) and ONB Merger Sub, Inc. (“ONB Merger Sub”) have entered into an Agreement and Plan of Merger, dated as of November 25, 2024 (the “merger agreement”). Under the merger agreement, ONB Merger Sub will first merge with and into Bremer (the “first step merger”), with Bremer as the surviving corporation in the first step merger as a wholly-owned subsidiary of Old National. Immediately following the first step merger, and as part of a single, integrated transaction, Bremer will then merge with and into Old National (the “second step merger” and together with the first step merger, the “mergers”), with Old National as the surviving corporation in the second step merger. Immediately following the second step merger, or at a later time as determined by Old National, Bremer’s wholly-owned banking subsidiary, Bremer Bank, a national banking association, will merge with and into Old National’s wholly-owned banking subsidiary, Old National Bank, a national banking association, with Old National Bank as the surviving bank (the “bank merger”).

As a result of the foregoing, based on the number of shares of Bremer Class A common stock and Bremer Class B common stock (together, the “Bremer common stock”) outstanding as of the date of the merger agreement, Old National expects to issue approximately 50.2 million shares of Old National common stock to Bremer shareholders upon completion of the mergers, which will result in current Bremer shareholders owning approximately 13.59% of outstanding Old National common stock.

Why am I receiving this proxy statement/prospectus?

We are sending this proxy statement/prospectus to you because it is a proxy statement being used by the Bremer board of directors to solicit proxies of Bremer shareholders in connection with approval and adoption of the merger agreement. It describes the proposals to be presented at the Bremer special meeting of shareholders (the “special meeting” or the “Bremer special meeting”).

This document is also a prospectus that is being delivered to Bremer shareholders because, in connection with the mergers, Old National will issue to Bremer shareholders shares of Old National common stock as merger consideration.

This proxy statement/prospectus contains important information about the merger agreement, the mergers and other related matters, the proposals being voted on at the Bremer special meeting and important information to consider in connection with an investment in Old National common stock. You should read it carefully and in its entirety. The enclosed materials allow you to have your shares of Bremer common stock voted by proxy without attending the Bremer special meeting. Your vote is important, and we encourage you to submit your proxy as soon as possible, whether or not you intend to attend the Bremer special meeting.

TABLE OF CONTENTS

What are Bremer shareholders being asked to vote on at the Bremer special meeting?

The Bremer board of directors is soliciting proxies from Bremer’s shareholders with respect to the following proposals:

•

a proposal to approve and adopt the merger agreement (the “merger proposal”); and

•

a proposal to adjourn the Bremer special meeting, if necessary or appropriate (the “adjournment proposal”).

What will Bremer shareholders receive in the mergers?

Under the terms and subject to the conditions set forth in the merger agreement, Bremer shareholders will receive cash and Old National common stock for each of their shares of Bremer Class A common stock and Bremer Class B common stock (together, the “Bremer common stock”). At the effective time of the first step merger, each outstanding share of Bremer common stock (except for dissenting shares, shares of treasury stock or shares owned by Bremer, Old National or ONB Merger Sub, in each case other than shares held in trust accounts, managed accounts, mutual funds and the like, or otherwise held in a fiduciary or agency capacity that are beneficially owned by third parties, or held, directly or indirectly, as a result of debts previously contracted) will be converted into the right to receive (i) $26.22 in cash without interest and (ii) 4.182 shares of Old National common stock. No fractional shares of Old National common stock will be issued in the mergers, and holders of Bremer common stock will be entitled to receive cash in lieu of fractional shares.

Based on the number of shares of Bremer common stock outstanding as of the date of the merger agreement, Old National expects to issue approximately 50.2 million shares of Old National common stock to Bremer shareholders upon completion of the mergers, which will result in current Bremer shareholders owning approximately 13.59% of outstanding Old National common stock.

How does the Bremer board of directors recommend that I vote at the Bremer special meeting?

The Bremer board of directors unanimously recommends that you vote “FOR” the merger proposal and “FOR” the adjournment proposal.

Will the value of the merger consideration change between the date of this proxy statement/prospectus and the time the mergers are completed?

Yes. Because the merger consideration is comprised of a fixed amount of cash consideration plus a fixed amount of shares of Old National common stock for each share of Bremer common stock, the value of the merger consideration will fluctuate based upon the market value of Old National common stock. Any fluctuation in the market price of Old National common stock after the date of this proxy statement/prospectus will change the value of the shares of Old National common stock that Bremer shareholders will receive upon completion of the mergers.

Based on the $26.22 in cash without interest and 4.182 shares of Old National common stock that each share of Bremer common stock would receive in the mergers, and the closing stock price of Old National common stock on the NASDAQ Stock Exchange, as reported by The Wall Street Journal, of $23.58 as of January 28, 2025, the value of the per share merger consideration payable to holders of Bremer common stock was approximately $124.83 as of such date.

Similar to virtually all publicly-traded stock, the trading price of Old National common stock will continue to change. We suggest that you obtain current market quotations for Old National common stock, which is currently traded on the NASDAQ Stock Exchange under the trading symbol “ONB”.

TABLE OF CONTENTS

Does Old National pay regular dividends on its shares of common stock?

Yes. Old National has traditionally paid a quarterly cash dividend on its shares of common stock. The payment of dividends is subject to approval by the Old National board of directors as well as legal and regulatory restrictions and safety and soundness considerations. Any payment of dividends in the future will depend, in large part, on Old National’s earnings, capital requirements, financial condition and other factors considered relevant by its board of directors.

Old National declared quarterly cash dividends of $0.14 per share on its common stock in each of 2024, 2023, 2022, and 2021. The amount of quarterly cash dividends paid on shares of Old National common stock is subject to change based on the quarterly dividend amounts approved by the Old National board of directors.

What are the U.S. federal income tax consequences of the mergers to Bremer shareholders?

The parties intend for the mergers, taken together, to qualify as a “reorganization” within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended (the “Code”). Therefore, U.S. holders of shares of Bremer common stock will recognize gain, but not loss, for U.S. federal income tax purposes in an amount equal to the lesser of (i) the amount of cash received for the cash portion of the merger consideration (other than cash received in lieu of a fractional share of Old National common stock) and (ii) the excess, if any, of (a) the sum of the amount of such cash and the fair value of the Old National common stock received in the mergers, over (b) the U.S. holder’s adjusted tax basis in the shares of Bremer common stock surrendered in the mergers. With respect to any cash received in lieu of a fractional share of Old National common stock, a U.S. holder will generally recognize gain or loss measured by the difference between the amount of cash received for such fractional share and the U.S. holder’s adjusted tax basis in its shares of Bremer common stock allocable to that fractional share.

The obligations of Old National and Bremer to complete the mergers are subject to the requirement that each of Old National and Bremer receive opinions from their respective tax counsel that the mergers, taken together, will qualify as a “reorganization” under Section 368(a) of the Code. You should be aware that the tax consequences of the mergers to you may depend upon your own situation. In addition, you may be subject to state, local, or foreign tax laws that are not discussed in this proxy statement/prospectus. You should therefore consult with your own tax advisor for a full understanding of the tax consequences to you of the mergers. For further information, see “Material U.S. Federal Income Tax Consequences of the Mergers.”

Are there any risks that I should consider in deciding whether to vote for the approval of the merger proposal?

Yes. You should read and carefully consider the risk factors set forth in the section of this proxy statement/prospectus entitled “Risk Factors.” You also should read and carefully consider the risk factors of Old National contained in the documents that are incorporated by reference into this proxy statement/prospectus.

If I am a Bremer shareholder, should I send in my Bremer stock certificate(s) now?

No. Please do not send in your Bremer stock certificate(s) with your proxy card. After the mergers, you will receive instructions for exchanging your Bremer stock certificates for the merger consideration. For further information, see “The Merger Agreement — Exchange of Shares.”

What should I do if I hold my shares of Bremer common stock in book-entry form?

If your shares of Bremer common stock are held in book-entry form, you are not required to take any additional actions in connection with the conversion of your shares of Bremer common stock into merger consideration at the effective time. After the completion of the mergers, shares of Bremer common stock held in book-entry form will automatically be exchanged for the merger consideration.

TABLE OF CONTENTS

When and where is the Bremer special meeting?

The Bremer special meeting will be held virtually via the Internet on Friday, March 7, 2025, at 8:00 a.m. Central Time.

Even if you plan to attend the Bremer special meeting, we recommend that you vote your shares of Bremer common stock in advance as described below so that your vote will be counted if you later decide not to or become unable to attend the special meeting. You will not be able to vote your shares of Bremer common stock held under the Bremer 401(k) Plan (the “Bremer 401(k) Plan shares”) or your shares of Bremer common stock (the “Bremer ESOP shares”) held under the Bremer Employees Stock Ownership Plan (the “Bremer ESOP”) at the special meeting as the deadline for voting these shares is 10:59 p.m. Central Time on March 3, 2025, which is 72 hours earlier than the general deadline due to these shares being held through the plans.

What constitutes a quorum for the Bremer special meeting?

A majority of the voting power of the shares entitled to vote at the meeting, present virtually or represented by proxy, shall constitute a quorum for the transaction of business at the special meeting. Abstentions will be included in determining the number of shares present at the special meeting for the purpose of determining the presence of a quorum.

What is the vote required to approve each proposal at the Bremer special meeting?

Merger proposal

•

Standard: Approval of the merger proposal requires the affirmative vote of a majority of the voting power of all shares of Bremer common stock entitled to vote thereon. Shares of Bremer Class A common stock and Bremer Class B common stock outstanding as of the record date will be entitled to vote together on the merger proposal.

•

Effect of abstentions and failure to vote: If you mark “ABSTAIN” on your proxy card or fail to vote (or fail to provide voting instructions for any Bremer 401(k) Plan shares or Bremer ESOP shares) with respect to the merger proposal, it will have the same effect as a vote “AGAINST” the merger proposal.

Adjournment proposal

•

Standard: Whether or not a quorum is present, approval of the adjournment proposal requires the affirmative vote of a majority of the voting power of the shares of Bremer common stock present at the special meeting and entitled to vote thereon. Shares of Bremer Class A common stock and Bremer Class B common stock outstanding as of the record date and present at the special meeting will be entitled to vote together on the adjournment proposal.

•

Effect of abstentions and failure to vote: If you mark “ABSTAIN” on your proxy card with respect to the adjournment proposal, it will have the same effect as a vote “AGAINST” the proposal. If you fail to vote (or fail to provide voting instructions for any Bremer 401(k) Plan shares or Bremer ESOP shares) with respect to the adjournment proposal, it will have no effect on the outcome of the proposal.

Are there any Bremer shareholders already committed to voting in favor of the merger proposal?

Yes. The trustees of the Otto Bremer Trust have entered into a trustee voting agreement with Old National, and each of the directors of Bremer (other than the trustees of the Otto Bremer Trust, who have separately entered into the trustee voting agreement) has entered into director voting agreement with Old National. In accordance with these voting agreements, the trustees and directors have agreed to vote “FOR” the approval and adoption of the merger agreement, subject to the terms of the trustee voting agreement and director voting agreements, as applicable. As of the record date for the Bremer special meeting of shareholders, the Otto Bremer Trust and directors collectively beneficially owned 86.20% of the outstanding shares of Bremer common stock. For information regarding the shareholder voting agreements and certain holders of shares of Bremer common stock, see “Shareholder Voting Agreements.”

TABLE OF CONTENTS

How can I vote my shares of Bremer common stock?

•

By telephone: by calling the toll-free number indicated on the accompanying proxy card and following the recorded instructions.

•

Even if you plan to attend the Bremer special meeting, we recommend that you vote your shares in advance as described below so that your vote will be counted if you later decide not to or become unable to attend the special meeting.

TABLE OF CONTENTS

If my shares are held through the Bremer 401(k) Plan or the Bremer ESOP, how do I vote my shares?

If you hold Bremer 401(k) Plan shares or Bremer ESOP shares, you must separately vote your holdings in each plan. You may vote the Bremer 401(k) Plan shares and Bremer ESOP shares by telephone, via the Internet or, if you receive a hard copy of this proxy statement/prospectus, by mail by completing, signing, dating and returning the accompanying voting instruction card for these shares in the enclosed postage-paid return envelope as described on the voting instruction card for each plan, which must be received by the deadline for shares held under the Bremer 401(k) Plan and Bremer ESOP, which is 72 hours earlier than the general deadline. If you hold Bremer common stock through both plans, you will have to complete separate voting instructions for each of these holdings in order for all of your shares held through the plans to be voted. The deadline for providing these instructions is 10:59 p.m. Central Time on March 3, 2025, which is 72 hours earlier than the deadline to vote any Bremer common stock that you hold in your name as a shareholder of record. This deadline differs because your voting instructions for the Bremer 401(k) Plan shares and the Bremer ESOP shares will be sent confidentially to the independent trustee for the plans, GreatBanc Trust Company (“GreatBanc”), which will vote these shares on behalf of plan participants in accordance with each plan participant’s voting instructions or as otherwise required consistent with its fiduciary duties to plan participants under applicable law.

If you do not provide instructions for your Bremer 401(k) Plan shares or Bremer ESOP shares, they will not be voted unless GreatBanc determines that voting the shares is required in accordance with its fiduciary duties to plan participants under applicable law. You may not vote Bremer 401(k) Plan shares or Bremer ESOP shares by returning a proxy card directly to Bremer or by voting at the Bremer special meeting.

Can I change my vote after I have delivered my proxy or voting instruction card?

Yes. If you are the record holder of your shares, you may revoke your proxy in any of the following ways:

•

Re-submitting your vote via the Internet or by telephone by 10:59 p.m. Central Time on March 6, 2025;

•

If you receive a hard copy of this proxy statement/prospectus, submitting another properly completed proxy card bearing a later date which is received by 10:59 p.m. Central Time on March 6, 2025;

•

Attending the special meeting virtually and voting at the special meeting via the special meeting website; or

•

Submitting a written notice that you are revoking your proxy. The notice must be sent to Bremer at 380 St. Peter Street, Suite 500, Saint Paul, Minnesota 55102, Attention: Amy J. Dorn, Corporate Secretary, and must be received by 10:59 p.m. Central Time on March 6, 2025.

If you hold your stock through the Bremer 401(k) Plan or the Bremer ESOP, you can change your vote by resubmitting your vote via the Internet or by telephone, or, if you receive a hard copy of this proxy statement/prospectus, by submitting another properly completed voting instruction card bearing a later date for these shares, but any changes must be received prior to 10:59 p.m. Central Time on March 3, 2025, which is 72 hours prior to the deadline for other shareholders.

What should I do if I receive more than one set of voting materials?

Bremer shareholders may receive more than one set of voting materials by mail, including multiple copies of this proxy statement/prospectus and multiple proxy cards or voting instruction cards. For example, if you hold shares of Bremer common stock of record directly in your name, under the Bremer 401(k) Plan and under the Bremer ESOP, you will receive a separate voting instruction card for each of the three ways that you may hold your shares. If you are a holder of record of Bremer common stock and your shares are registered in more than one name, you will receive more than one proxy card. Please vote via the Internet, by telephone, or, if you receive a hard copy of this proxy statement/prospectus, by mail by completing, signing, dating and returning each proxy card and voting instruction card that you receive or otherwise follow the voting instructions set forth in this proxy statement/prospectus to ensure that you vote every share of Bremer common stock that you own.

TABLE OF CONTENTS

Will Bremer be required to submit the merger proposal to its shareholders even if the Bremer board of directors has withdrawn, modified or qualified its recommendation?

Yes. Unless the merger agreement is terminated before the Bremer special meeting, Bremer is required to submit the merger proposal to its shareholders even if the Bremer board of directors has withdrawn, modified or qualified its recommendation that Bremer shareholders approve and adopt the merger agreement.

Are Bremer shareholders entitled to appraisal rights?

Yes. Under Section 302A.471 and 302A.473 of the Minnesota Business Corporation Act (“MBCA”), dissenting shareholders may seek a court-determined “fair value” of such shareholder’s shares of Bremer common stock. See “Appraisal or Dissenters’ Rights in the Mergers” in this proxy statement/prospectus for a complete discussion of the appraisal or dissenters’ rights available to holders of Bremer common stock and a summary of the steps required to assert such rights.

When do you expect to complete the mergers?

Old National and Bremer expect to complete the mergers in the middle of 2025. However, neither Old National nor Bremer can assure you of when or if the mergers will be completed. Bremer must obtain the approval of the merger proposal by the Bremer shareholders at the Bremer special meeting, and Old National must obtain the required regulatory approvals. In addition, each party is required to satisfy certain other closing conditions.

What happens if the mergers are not completed?

If the mergers are not completed, Bremer shareholders will not receive any consideration from Old National for their shares of Bremer common stock in connection with the mergers. Instead, Bremer will remain an independent company, and your shares of Bremer common stock will remain outstanding. In addition, if the merger agreement is terminated in certain circumstances, a termination fee may be required to be paid by Bremer to Old National. See “The Merger Agreement — Termination Fee” for a complete discussion of the circumstances under which any such termination fee would be required to be paid.

Who should I call with questions?

If you have any questions concerning the merger agreement, the mergers or this proxy statement/prospectus, would like additional copies of this proxy statement/prospectus or need help voting your shares of Bremer common stock, please contact Amy J. Dorn, Corporate Secretary of Bremer, at (651) 964-7145.

TABLE OF CONTENTS

SUMMARY

This summary highlights selected information from this proxy statement/prospectus. It may not contain all of the information that is important to you. You are urged to read carefully the entire proxy statement/prospectus, including the annexes, and the other documents to which we refer in order to fully understand the mergers and the merger agreement. In addition, we incorporate by reference important business and financial information about Old National into this proxy statement/prospectus. You may obtain the information incorporated by reference into this proxy statement/prospectus without charge by following the instructions in the section entitled “Where You Can Find More Information.” Each item in this summary refers to the page of this proxy statement/prospectus on which the subject is discussed in more detail.

The Mergers (page 38)

The terms and conditions of the mergers are contained in the merger agreement, a copy of which is attached to this proxy statement/prospectus as Annex A and is incorporated by reference herein in its entirety. All descriptions in this summary and elsewhere in this proxy statement/prospectus of the terms and conditions of the mergers are qualified in their entirety by reference to the merger agreement. Please read the merger agreement carefully for a more complete understanding of the mergers.

Under the merger agreement, ONB Merger Sub will first merge with and into Bremer (the “first step merger”), with Bremer as the surviving corporation in the first step merger as a wholly-owned subsidiary of Old National. Immediately following the first step merger, and as part of a single, integrated transaction, Bremer will then merge with and into Old National (the “second step merger” and together with the first step merger, the “mergers”), with Old National as the surviving corporation in the second step merger. Immediately following the second step merger, or at a later time as determined by Old National, Bremer’s wholly-owned banking subsidiary, Bremer Bank, a national banking association, will merge with and into Old National’s wholly-owned banking subsidiary, Old National Bank, a national banking association, with Old National Bank as the surviving bank (the “bank merger”).

Because the merger consideration is comprised of a fixed amount of cash consideration plus a fixed amount of shares of Old National common stock for each share of Bremer common stock, the market value of the merger consideration will fluctuate with the market price of Old National common stock and will not be known at the time Bremer shareholders vote on the merger agreement. Based on the closing stock price of Old National common stock on the NASDAQ Stock Exchange, as reported by The Wall Street Journal, of $23.58 as of January 28, 2025, the value of the per share merger consideration payable to holders of Bremer common stock was approximately $124.83 as of such date. We suggest that you obtain a current market quotation for Old National, which is currently traded on the NASDAQ Stock Exchange under the trading symbol “ONB”. Bremer common stock is not listed or quoted on any exchange.

The following table shows the closing sales prices of Old National common stock on November 22, 2024, the last trading day before the public announcement of the merger agreement, and on January 28, 2025. The table also shows the implied value of the merger consideration to be issued in exchange for each share of Bremer common stock, reflecting (i) $26.22 in cash without interest and (ii) the exchange ratio of 4.182.

Bremer’s Reasons for the Mergers; Recommendation of the Bremer Board of Directors (page 42)

The Bremer board of directors has unanimously (i) determined that the merger agreement and the transactions contemplated thereby, including the mergers and the bank merger, are advisable and in the best interests of Bremer and the Bremer shareholders and (ii) approved and adopted the execution, delivery and performance by Bremer of the merger agreement and the consummation of the transactions contemplated thereby, including the mergers and the bank merger. The Bremer board of directors unanimously recommends that Bremer shareholders vote “FOR” the merger proposal and “FOR” the adjournment proposal. For the factors considered by the Bremer board of directors in reaching its decision to adopt the merger agreement, see “The Mergers — Bremer’s Reasons for the Mergers; Recommendation of The Bremer Board of Directors.”

Opinion of Bremer’s Financial Advisor (page 44)

Bremer retained J.P. Morgan Securities LLC (“J.P. Morgan”) to act as its financial advisor in connection with the mergers. At the meeting of Bremer’s board of directors held on November 24, 2024, J.P. Morgan rendered its oral opinion to the Bremer board of directors, which was subsequently confirmed in writing on November 24, 2024, to the effect that, as of such date and based upon and subject to the factors and assumptions made, procedures followed, matters considered and limitations and qualifications set forth in its opinion, the merger consideration to be paid to the holders of Bremer common stock in the first step merger was fair, from a financial point of view, to such holders (collectively, the “Bremer shareholders”).

The full text of the written opinion of J.P. Morgan, dated November 24, 2024, which sets forth, among other things, the assumptions made, procedures followed, matters considered and qualifications and limits on the review undertaken by J.P. Morgan in rendering its fairness opinion, is attached as Annex D to this proxy statement/prospectus and is incorporated herein by reference. The summary of the opinion of J.P. Morgan set forth in this proxy statement/prospectus is qualified in its entirety by reference to the full text of such opinion. Bremer shareholders are urged to read the opinion in its entirety. J.P. Morgan’s written opinion was addressed to the Bremer board of directors (in its capacity as such) in connection with and only for the purposes of its evaluation of the merger consideration to be paid to the Bremer shareholders and did not address any other aspect of the mergers. The issuance of J.P. Morgan’s opinion was approved by a fairness committee of J.P. Morgan. The opinion does not constitute a recommendation to any Bremer shareholder as to how such Bremer shareholder should vote with respect to the proposed mergers or any other matter.

For more information, see the section entitled “Opinion of Bremer’s Financial Advisor” beginning on page 44 and Annex D to this joint proxy statement/prospectus.

Bremer Will Hold Its Special Meeting on Friday, March 7, 2025 (page 31)

The special meeting will be held virtually via the Internet on Friday, March 7, 2025, at 8:00 a.m. Central Time. At the special meeting, Bremer shareholders will be asked to consider and vote upon the following matters:

•

a proposal to approve and adopt the merger agreement (the “merger proposal”); and

•

a proposal to adjourn the Bremer special meeting, if necessary or appropriate (the “adjournment proposal”).

TABLE OF CONTENTS

The Bremer board of directors has fixed the close of business on January 24, 2025 as the record date for determining the holders of Bremer common stock entitled to receive notice of and to vote at the special meeting.

As of the record date, there were 11,999,785 shares of Bremer common stock outstanding and entitled to vote at the Bremer special meeting, held by approximately 78 holders of record. Each share of Bremer common stock entitles the holder thereof to one vote at the Bremer special meeting on each proposal to be considered at the special meeting of shareholders.

Approval of the merger proposal requires the affirmative vote of a majority of the voting power of all shares of Bremer common stock entitled to vote thereon. Shares of Bremer Class A common stock and Bremer Class B common stock outstanding as of the record date will be entitled to vote together on the merger proposal. If you fail to vote (or fail to provide voting instructions for any Bremer 401(k) Plan shares or Bremer ESOP shares) or mark “ABSTAIN” on your proxy card with respect to the merger proposal, it will have the same effect as a vote “AGAINST” the merger proposal.

Whether or not a quorum is present, approval of the adjournment proposal requires the affirmative vote of a majority of the voting power of the shares of Bremer common stock present at the special meeting and entitled to vote thereon. Shares of Bremer Class A common stock and Bremer Class B common stock outstanding as of the record date and present at the special meeting will be entitled to vote together on the adjournment proposal. If you mark “ABSTAIN” on your proxy with respect to the adjournment proposal, it will have the same effect as a vote “AGAINST” the adjournment proposal. If you fail to vote (or fail to provide voting instructions for any Bremer 401(k) Plan shares or Bremer ESOP shares) with respect to the adjournment proposal, it will have no effect on the outcome of the adjournment proposal.

For further information, see “Information About the Bremer Special Meeting.”

Shareholder Voting Agreements (page 76)

The trustees of the Otto Bremer Trust have entered into a trustee voting agreement with Old National, and each of the directors of Bremer (other than the trustees of the Otto Bremer Trust, who have separately entered into the trustee voting agreement) has entered into director voting agreement with Old National. In accordance with these voting agreements, the trustees and directors, as applicable, have agreed to vote “FOR” the approval and adoption of the merger agreement and “FOR” the adjournment proposal, subject to the terms of the trustee voting agreement and director voting agreement, as applicable. As of the record date for the Bremer special meeting, the Otto Bremer Trust and the directors of Bremer owned collectively and beneficially 86.20% of the outstanding shares of Bremer common stock. For information regarding the shareholder voting agreements and certain holders of shares of Bremer common stock, see “Shareholder Voting Agreements.”

Material U.S. Federal Income Tax Consequences of the Mergers (page 78)

The parties intend for the mergers, taken together, to qualify as a “reorganization” within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended (the “Code”). Therefore, U.S. holders (as defined in the section of this proxy statement/prospectus titled “Material U.S. Federal Income Tax Consequences of the Merger — In General”) of the shares of Bremer common stock will recognize gain, but not loss, for U.S. federal income tax purposes in an amount equal to the lesser of (i) the amount of cash received (other than cash received in lieu of a fractional share of Old National common stock) and (ii) the excess, if any, of (a) the sum of the amount of such cash and the fair value of the Old National common stock received in the mergers, over (b) the U.S. holder’s adjusted tax basis in the shares of Bremer common stock surrendered in the mergers. With respect to any cash received in lieu of a fractional share of Old National common stock, a U.S. holder will generally recognize gain or loss measured by the difference between the amount of cash received for such fractional share and the U.S. holder’s adjusted tax basis in its shares of Bremer common stock allocable to that fractional share.

The obligations of Old National and Bremer to complete the mergers are subject to, among other conditions as described in this proxy statement/prospectus and the merger agreement, the requirement that each of Old National and Bremer receive opinions from their respective tax counsel that, on the basis of facts,

TABLE OF CONTENTS

representations and assumptions set forth or referred to in such opinion, the mergers, taken together, will qualify as a “reorganization” under Section 368(a) of the Code. If any such representations and assumptions are incorrect, incomplete, or false, or are violated, the validity of the opinion described above may be affected, and the tax consequences of the mergers could differ from those consequences described in this proxy statement/prospectus.

You should be aware that the tax consequences of the mergers to you may depend upon your own situation. In addition, you may be subject to state, local or foreign tax laws that are not discussed in this proxy statement/prospectus. You should therefore consult with your own tax advisor for a full understanding of the tax consequences to you of the mergers. For a more complete discussion of the material U.S. federal income tax consequences of the mergers, see the section of this proxy statement/prospectus entitled “Material U.S. Federal Income Tax Consequences of the Mergers” beginning on page 78.

All Bremer shareholders should consult their own tax advisors for a full understanding of the particular tax consequences of the mergers to them.

Interests of Bremer’s Directors and Executive Officers in the Mergers (page 53)

In considering the recommendation of the Bremer board of directors with respect to the mergers, Bremer shareholders should be aware that Bremer’s directors and executive officers have interests in the mergers that may be different from, or in addition to, the interests of the other Bremer shareholders. The Bremer board of directors was aware of and considered these interests during its deliberations of the merits of the mergers and in determining to recommend to Bremer shareholders that they vote for the merger proposal and thereby approve the transactions contemplated by the merger agreement, including the mergers and the bank merger. Those interests include, among others:

•

The trustees of the Otto Bremer Trust (two of whom currently serve as directors of Bremer) entered into a trustee voting agreement with Old National, and each of Bremer’s directors (other than the trustees of the Otto Bremer Trust, who have separately entered into the trustee voting agreement) entered into a director voting agreement with Old National, which voting agreements obligate the trustees and the directors to vote their shares in favor of approval and adoption of the merger proposal and the adjournment proposal.

•

The trustees of the Otto Bremer Trust (two of whom currently serve as directors of Bremer) entered into an investor agreement with Old National (the “investor agreement”). Pursuant to the merger agreement and the investor agreement, one of the trustees of the Otto Bremer Trust immediately prior to the effective time of the mergers will be appointed to the Old National board of directors.

•

The Chief Executive Officer and Chief Operating Officer/Chief Financial Officer of Bremer have preexisting arrangements with Bremer that provide for certain payments or benefits upon the completion of the mergers and/or if their employment is terminated under certain circumstances following the completion of the mergers.

•

Old National has agreed to provide certain ongoing indemnification and insurance coverage to the directors and executive officers of Bremer following the mergers for certain acts or omissions occurring prior to the mergers.

For a more complete description of these interests, see the section entitled “The Mergers — Interests of Bremer’s Directors and Executive Officers in the Mergers.”

Regulatory Approvals Required for the Mergers (page 56)

Subject to the terms of the merger agreement, both Old National and Bremer have agreed to use their reasonable best efforts and to cooperate to promptly prepare and file, or cause to be prepared and filed, all necessary applications, notices and other documentation to obtain as soon as practicable all regulatory approvals necessary or advisable to consummate the transactions contemplated by the merger agreement. These include approvals from, among others, the Board of Governors of the Federal Reserve System (“Federal Reserve”), for the mergers and the Office of the Comptroller of the Currency (“OCC”) for the bank merger. The initial filing of regulatory applications to the OCC and the Federal Reserve occurred on January 20, 2025 and January 21, 2025, respectively.

TABLE OF CONTENTS

Although neither Old National nor Bremer knows of any reason why it cannot obtain these regulatory approvals in a timely manner, Old National and Bremer cannot be certain when or if they will be obtained, or that the granting of these regulatory approvals will not involve the imposition of conditions on the completion of the mergers or the bank merger. For more information, see “The Mergers — Regulatory Approvals Required for the Mergers.”

Conditions to Complete the Mergers (page 72)

Each party’s obligation to complete the mergers is subject to the satisfaction or waiver of certain conditions, including: (i) the approval of the merger agreement by the requisite vote of the Bremer shareholders; (ii) the receipt of all required regulatory approvals and expiration or termination of all statutory waiting periods in respect thereof, and no such regulatory approval shall have resulted in the imposition of a “materially burdensome regulatory condition”, as defined in the merger agreement; (iii) authorization for listing on the NASDAQ Stock Exchange of the shares of Old National common stock to be issued in the mergers; (iv) effectiveness of the registration statement on Form S-4 with respect to the shares of the Old National common stock to be issued in the mergers; (v) the absence of any order, injunction, decree or other legal restraint preventing the completion of the mergers or the transactions contemplated by the merger agreement or making the completion of the mergers or the transactions contemplated by the merger agreement illegal; (vi) the accuracy of the representations and warranties of the other party, subject to specified materiality standards; (vii) performance in all material respects by the other party of its obligations under the merger agreement; and (viii) receipt by each of Old National and Bremer of an opinion of their respective tax counsel that, on the basis of facts, representations and assumptions set forth or referred to in such opinion, the mergers, taken together, will qualify as a “reorganization” under Section 368(a) of the Code. In addition, Old National’s obligation to consummate the mergers is subject to Bremer’s adjusted tangible shareholder’s equity exceeding a specified minimum value as of the month-end at least five business days before the date on which the last of the other closing conditions is satisfied.

Neither Old National nor Bremer can be certain when, or if, the conditions to the mergers will be satisfied or waived, or that the mergers will be completed. For more information, see “The Merger Agreement — Conditions to Complete the Mergers.”

Termination of the Merger Agreement (page 73)

The merger agreement may be terminated prior to the effective time under the following circumstances:

•

by mutual written consent of Old National and Bremer;

•

by either Old National or Bremer if any governmental authority that must grant a requisite regulatory approval has denied approval of the mergers or the bank merger and such denial has become final and nonappealable or any governmental authority of competent jurisdiction has issued a final and nonappealable order, injunction, decree or other legal restraint or prohibition permanently enjoining or otherwise prohibiting or making illegal the mergers or the bank merger, unless the failure to obtain a requisite regulatory approval is due to the failure of the party seeking to terminate the merger agreement to perform or observe its covenants and agreements under the merger agreement;

•

by either Old National or Bremer if the mergers have not been completed on or before November 25, 2025 (the “termination date”), unless the failure of the mergers to be completed by such date is due to the failure of the party seeking to terminate the merger agreement to perform or observe its covenants and agreements under the merger agreement; provided that, if on such date, the closing conditions relating to requisite regulatory approvals set forth in the merger agreement shall not have been satisfied or waived, but all other conditions to closing have been satisfied or waived, the termination date shall be automatically extended to February 25, 2026; provided further, that if all closing conditions in the merger agreement are satisfied on a date that occurs prior to the termination date but under the terms of the merger agreement the closing would occur after the termination date (the “specified date”), the termination date shall be extended to the specified date.

•

by either Old National or Bremer (provided that the terminating party is not then in material breach of any representation, warranty, obligation, covenant or other agreement contained in the merger

TABLE OF CONTENTS

agreement) if there is a breach of any of the obligations, covenants or agreements or any of the representations or warranties (or any such representation or warranty ceases to be true) set forth in the merger agreement on the part of Bremer, in the case of a termination by Old National, or Old National or ONB Merger Sub, in the case of a termination by Bremer, which breach or failure to be true either individually or in the aggregate would constitute, if occurring or continuing on the date the mergers is completed, the failure of a closing condition of the terminating party and which is not cured within forty-five (45) days following written notice to the party committing such breach, or by its nature or timing cannot be cured during such period (or such fewer days as remain prior to the termination date); or

•

by Old National prior to such time as the requisite Bremer vote is obtained, if (i) the Bremer board of directors shall have (a) failed to recommend in this proxy statement/prospectus that the shareholders of Bremer approve the merger agreement, or withheld, withdrawn, modified or qualified such recommendation in a manner adverse to Old National, (b) adopted, approved, recommended or endorsed an alternative acquisition proposal or publicly disclosed its intention to do so, or failed to publicly and without qualification recommend such alternative acquisition proposal or reaffirm its recommendation that the shareholders of Bremer approve the merger agreement, within ten (10) business days (or such fewer number of days as remains prior to the Bremer special meeting) after an alternative acquisition proposal is made public or any request by Old National to do so, or (c) publicly proposed to do any of the foregoing, or (ii) Bremer or Bremer’s board of directors has breached in any material respect its obligations relating to shareholder approval or the non-solicitation of acquisition proposals.

For more information, see “The Merger Agreement — Termination of the Merger Agreement.”

Termination Fee (page 74)

If the merger agreement is terminated under certain circumstances Bremer will be required to pay to Old National a termination fee equal to $55,000,000.

For more information, see “The Merger Agreement — Termination Fee.”

The Rights of Bremer Shareholders Will Change as a Result of the Mergers (page 87)

The rights of Bremer shareholders will change as a result of the mergers due to differences in Old National’s and Bremer’s governing documents. The rights of Bremer shareholders are governed by Minnesota law and by Bremer’s restated articles of incorporation (the “Bremer articles of incorporation”), amended and restated bylaws (the “Bremer bylaws”) and that certain Plan of Reorganization, dated February 9, 1989 (the “Bremer plan of reorganization”). Upon the completion of the mergers, Bremer shareholders immediately prior to the effective time will become Old National shareholders, as the continuing legal entity after the mergers, and their rights as Old National shareholders will therefore be governed by Indiana law and the Old National amended and restated articles of incorporation (the “Old National articles of incorporation”) and amended and restated bylaws (the “Old National bylaws”).

See “Comparison of Shareholders’ Rights” for a description of the material differences in shareholders’ rights under each of the Old National and Bremer governing documents.

Accounting Treatment (page 78)

The mergers will be accounted for as an acquisition of Bremer by Old National under the acquisition method of accounting in accordance with generally accepted accounting principles in the United States (“U.S. GAAP”) for financial reporting and accounting purposes.

Public Trading Markets (page 58)

Old National common stock is listed for trading on the NASDAQ Stock Exchange under the symbol “ONB”. Following the mergers, shares of Old National common stock will continue to be listed for trading on the NASDAQ Stock Exchange.

RISK FACTORS

In addition to general investment risks and the other information contained in or incorporated by reference into this proxy statement/prospectus, including the matters addressed under the section “Cautionary Statement Regarding Forward-Looking Statements,” you should carefully consider the following risk factors relating to the consummation of the mergers and to Old National following the mergers in deciding how to vote for the proposals presented in this proxy statement/prospectus.

Because the market price of Old National common stock will fluctuate, Bremer shareholders cannot be certain of the market value of the merger consideration they will receive.

In the mergers, each share of Bremer common stock issued and outstanding immediately prior to the effective time (except for dissenting shares, shares of treasury stock or shares owned by Bremer, Old National or ONB Merger Sub, in each case other than shares held in trust accounts, managed accounts, mutual funds and the like, or otherwise held in a fiduciary or agency capacity that are beneficially owned by third parties, or held, directly or indirectly, as a result of debts previously contracted) will be converted into the right to receive (i) $26.22 in cash without interest, and (ii) 4.182 shares Old National common stock. No fractional shares of Old National common stock will be issued in the mergers, and holders of Bremer common stock will be entitled to receive cash in lieu of fractional shares. The number of shares of Old National common stock received in the mergers is fixed and will not be adjusted for changes in the market price of Old National common stock or Bremer common stock. Changes in the price of Old National common stock or Bremer common stock between now and the effective time of the first step merger will affect the value that Bremer shareholders will receive in the mergers. Neither Old National nor Bremer is permitted to terminate the merger agreement as a result of any increase or decrease in the market price of Old National common stock.

Stock price changes may result from a variety of factors, including general market and economic conditions, changes in Old National’s or Bremer’s respective businesses, operations, financial performance or prospects, volatility in the prices of securities in global financial markets, including market prices of Old National and other banking companies, regulatory considerations and tax laws, many of which are beyond Old National’s and Bremer’s control. Therefore, at the time of the Bremer special meeting, Bremer shareholders will not know the market value of the consideration that Bremer shareholders will receive at the effective time

The market price of Old National common stock after the mergers may be affected by factors different from those currently affecting the shares of Old National common stock.

Upon consummation of the mergers, Bremer shareholders will become Old National shareholders. Old National’s business currently differs, and may differ in the future, in certain respects from that of Bremer and certain adjustments may be made to Old National’s business as a result of the mergers. Accordingly, the results of operations of the combined company and the market price of Old National common stock after the completion of the mergers may be affected by factors different from those currently affecting the results of operations of Old National. For a discussion of the business of Old National and of certain factors to consider in connection with that business, see the documents incorporated by reference into this proxy statement/prospectus and referred to under “Where You Can Find More Information” beginning on page 103.

There has been no public market for Bremer common stock and the lack of a public market may make it more difficult to determine the fair value of Bremer common stock than if there were such a public market.

The outstanding shares of Bremer common stock are privately held and are not traded on any public market. The lack of a public market may make it more difficult to determine the fair value of Bremer than if the outstanding shares of Bremer common stock were traded publicly. The consideration to be paid to Bremer shareholders in the mergers was determined based on negotiations between the parties and likewise may not be indicative of the price at which the outstanding shares of Bremer common stock may have traded on a public market. Prior to approving the merger agreement, the Bremer board of directors received an opinion of J.P. Morgan to the effect that, as of the date of such opinion and based upon and subject to the factors and assumptions made, procedures followed, matters considered and limitations and qualifications set forth in such opinion, the merger consideration to be paid to the holders of Bremer common stock in the

TABLE OF CONTENTS

mergers was fair, from a financial point of view, to Bremer’s shareholders. For further information, see the section entitled “The Mergers — Opinion of Bremer’s Financial Advisor.”

Combining Old National and Bremer may be more difficult, costly or time-consuming than expected, and the anticipated benefits and cost savings of the mergers may not be realized.

Old National and Bremer have operated and, until the completion of the mergers will continue to operate, independently. The success of the mergers, including anticipated benefits and cost savings, will depend, in part, on Old National’s and Bremer’s ability to successfully combine and integrate the businesses of Old National and Bremer in a manner that permits growth opportunities and does not materially disrupt existing customer relations or result in decreased revenues due to loss of customers. It is possible that the integration process could result in the loss of key employees, the disruption of either company’s ongoing businesses or inconsistencies in standards, controls, procedures and policies that adversely affect the combined company’s ability to maintain relationships with customers, depositors or employees or to achieve the anticipated benefits and cost savings of the mergers. The loss of key employees of Bremer could adversely affect Old National’s ability to successfully conduct its business, which could have an adverse effect on Old National’s financial results and the value of Old National’s common stock after the mergers. In addition, Old National may not be able to locate suitable replacements for any key Bremer employees who leave the combined company.

Although Old National has significant integration experience from prior merger transactions, if Old National and Bremer experience difficulties with the integration process, the anticipated benefits of the mergers may take longer to realize than expected or may not be realized fully or at all. As with any merger of financial institutions, there also may be business disruptions that cause Old National and/or Bremer to lose customers or cause customers to remove their accounts from Old National and/or Bremer and move their business to competing financial institutions. Integration efforts between the two companies may also divert management attention and resources. These integration matters could have an adverse effect on each of Old National and Bremer during this transition period and for an undetermined period after completion of the mergers on the combined company.

Regulatory approvals may not be received, may take longer than expected or may impose conditions that are not presently anticipated or that could have an adverse effect on the combined company following the mergers.

Before the mergers may be completed, Old National and Bremer must obtain all necessary approvals or waivers from the OCC and the Federal Reserve. Other approvals, waivers or consents from regulators could also be required. In determining whether to grant these approvals, the regulators consider a variety of factors, including the regulatory standing of each party and the factors described under “The Mergers — Regulatory Approvals Required for the Mergers.” An adverse development in either party’s regulatory standing or these factors could result in an inability to obtain approval or delay their receipt. These regulators may impose conditions on the completion of the mergers or require changes to the terms of the mergers. Such conditions or changes could have the effect of delaying or preventing completion of the mergers or imposing additional costs on or limiting the revenues of the combined company following the mergers, any of which might have an adverse effect on the combined company following the mergers.

Additionally, under the terms of the merger agreement, Old National and Bremer are not required to take actions or agree to conditions in connection with obtaining consents, approvals and authorizations of governmental entities that would reasonably be expected to have a material adverse effect on Old National and its subsidiaries, taken as a whole, after giving effect to the mergers (a “materially burdensome regulatory condition”). For further information, see “The Mergers — Regulatory Approvals Required for the Mergers.”

Certain of Bremer’s directors and executive officers have interests in the mergers that may differ from the interests of Bremer shareholders.

Bremer shareholders should be aware that some of Bremer’s directors and executive officers have interests in the mergers that may be different from, or in addition to, the interests of the other Bremer shareholders generally. These interests and arrangements may create potential conflicts of interest. The Bremer board of directors was aware of these interests and considered these interests, among other matters,

TABLE OF CONTENTS

when making its decision to approve the merger agreement and in recommending that Bremer shareholders vote in favor of approving and adopting the merger agreement.

For a more complete description of these interests, see “The Mergers — Interests of Bremer’s Directors and Executive Officers in the Mergers.”

Termination of the merger agreement could negatively impact Bremer.

If the merger agreement is terminated, there may be various adverse consequences, and Bremer may experience negative reactions from its customers and employees. If the merger agreement is terminated under certain circumstances, Bremer may be required to pay Old National a termination fee of $55,000,000.

Old National and Bremer will be subject to business uncertainties and contractual restrictions while the mergers are pending, which could disrupt Old National’s and Bremer’s relationships with their customers, suppliers, business partners and others, as well as their operating results and business generally.

Whether or not the mergers are ultimately consummated, uncertainty about the effect of the mergers on employees and customers may have an adverse effect on Old National and Bremer and, consequently, the combined company. These uncertainties may impair Old National’s and Bremer’s ability to attract, retain and motivate key personnel until the mergers are completed, and could cause customers and others that deal with Old National or Bremer to seek to change existing business relationships with Old National or Bremer, respectively. In addition, subject to certain exceptions, Bremer and Old National have each agreed to operate its business in the ordinary course consistent with past practice in all material respects and use reasonable best efforts to preserve its business organization, employees and business relationships prior to the closing of the mergers. See “The Merger Agreement — Covenants and Agreements” for a description of the restrictive covenants applicable to Bremer and Old National.

The shares of Old National common stock to be received by Bremer shareholders as a result of the mergers will have different rights from the shares of Bremer common stock.

In the mergers, Bremer shareholders will become Old National shareholders and their rights as Old National shareholders will be governed by Indiana law and the governing documents of Old National following the mergers. The rights associated with Old National common stock are different from the rights associated with Bremer common stock. See “Comparison of Shareholders’ Rights” for a discussion of the different rights associated with Old National common stock.

Old National and Bremer are expected to incur significant costs related to the mergers and integration. If the mergers are not completed, Old National and Bremer will have incurred substantial expenses without realizing the expected benefits of the mergers.

Each of Old National and Bremer has incurred and will incur substantial expenses in connection with the negotiation and completion of the mergers. These costs include legal, financial advisory, accounting, consulting and other advisory fees, severance/employee benefit- related costs, filing fees and other regulatory fees, printing costs and other related costs. Some of these costs are payable by either Old National or Bremer regardless of whether or not the mergers are completed. If the mergers are not completed, Old National and Bremer would have to recognize these expenses without realizing the expected benefits of the mergers.

The merger agreement limits Bremer’s ability to pursue alternative acquisition proposals, requires Bremer to pay a termination fee of $55,000,000 under limited circumstances, including circumstances relating to other acquisition proposals.

The merger agreement prohibits Bremer from initiating, soliciting, knowingly encouraging or knowingly facilitating certain alternative third-party acquisition proposals. For further information, see “The Merger Agreement — Agreement Not to Solicit Other Offers.” The merger agreement also provides that Bremer will be required to pay a termination fee to Old National in the amount of $55,000,000 in the event that the merger agreement is terminated under certain circumstances, including an adverse recommendation change by the Bremer board of directors. For further information, see “The Merger Agreement — Termination

TABLE OF CONTENTS

Fee.” These provisions might discourage a potential competing acquiror that might have an interest in acquiring all or a significant part of Bremer from considering or proposing such an acquisition.

Bremer shareholders will have a reduced ownership and voting interest in the combined company after the mergers and will exercise less influence over management, as compared to their ownership and voting interests in Bremer.

Bremer shareholders currently have the right to vote in the election of the Bremer board of directors and on other matters affecting Bremer. Upon completion of the mergers, each Bremer shareholder who receives shares of Old National common stock will become an Old National shareholder and will have the right to vote in the election of directors and on other matters, but with a percentage ownership of Old National that is smaller than such shareholder’s current percentage ownership of Bremer. Based on the number of shares of Bremer common stock outstanding on November 25, 2024, the date of the merger agreement, and the shares of Old National common stock expected to be issued in the mergers, the Bremer shareholders as a group will receive shares in the mergers constituting approximately 13.59% of the outstanding shares of Old National common stock immediately after the mergers have been completed. Because of this, Bremer shareholders may have less influence on the management and policies of the combined company than they now have on the management and policies of Bremer.

The fairness opinion received by the Bremer board of directors from J.P. Morgan has not been, and is not expected to be, updated to reflect any changes in circumstances that may have occurred since the date of such opinion.

The fairness opinion of J.P. Morgan was rendered to the Bremer board of directors on November 24, 2024. Changes in the operations and prospects of Bremer, general market and economic conditions and other factors which may be beyond the control of Bremer may have altered the value of Bremer and/or the value of the merger consideration to be received by Bremer shareholders in the mergers. The opinion from J.P. Morgan, dated November 24, 2024 and attached to this proxy statement/prospectus as Annex D, does not speak as of any date other than the date of such opinion.

UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL DATA

Introduction

The following unaudited pro forma condensed combined financial data is based on the separate historical financial statements of Old National and Bremer after giving effect to the mergers. The unaudited pro forma condensed combined financial data has been prepared in accordance with Article 11 of Regulation S-X of the SEC and should be read in conjunction with the accompanying notes.

The unaudited pro forma condensed combined balance sheet as of September 30, 2024 combines the unaudited consolidated balance sheet of Old National as of September 30, 2024 with the unaudited consolidated balance sheet of Bremer as of September 30, 2024, giving effect to adjustments that depict the accounting for the mergers and the full physical settlement of the forward sale agreements. See “Description of Old National Capital Stock — Old National Common Stock — Forward Sale Agreements” for more information on the forward sale agreements.

The unaudited pro forma condensed combined statement of income for the year ended December 31, 2023, combines the audited consolidated statement of income of Old National for the year ended December 31, 2023, with the audited consolidated statement of income of Bremer for the year ended December 31, 2023, giving effect to the accounting for the mergers and the forward sale agreements as if adjustments were made and the full physical settlement of the forward sale agreements occurred on January 1, 2023.

The unaudited pro forma condensed combined statement of income for the nine months ended September 30, 2024, combines the unaudited consolidated statement of income of Old National for the nine months ended September 30, 2024, with the unaudited consolidated statement of income of Bremer for the nine months ended September 30, 2024, giving effect to adjustments that depict the accounting for the mergers and the forward sale agreements as if adjustments were made and the full physical settlement of the forward sale agreements occurred on January 1, 2023. Old National’s acquisition of CapStar Financial Holdings, Inc., which was completed on April 1, 2024, is not reflected in the unaudited pro forma condensed combined statement of income for the nine months ended September 30, 2024 as presented below, as such acquisition (individually, and when considered together with all other individually insignificant transactions by Old National since December 31, 2023) was not considered significant under Regulation S-X.

The unaudited pro forma condensed combined financial data was derived from, and should be read in conjunction with, the following historical financial statements and the accompanying notes, which are included or incorporated by reference into this proxy statement/prospectus:

•

The historical audited consolidated financial statements of Old National as of and for the year ended December 31, 2023 (included in Old National’s Annual Report on Form 10-K for the year ended December 31, 2023);

•

The historical unaudited consolidated financial statements of Old National as of and for the nine months ended September 30, 2024 (included in Old National’s Quarterly Report on Form 10-Q for the fiscal quarter ended September 30, 2024);

•

The historical audited consolidated financial statements of Bremer as of and for the year ended December 31, 2023 (included in this proxy statement/prospectus); and

•

The historical unaudited consolidated financial statements of Bremer as of and for the nine months ended September 30, 2024 (included in this proxy statement/prospectus).

The unaudited pro forma condensed combined financial data should also be read together with other financial data included elsewhere or incorporated by reference into this proxy statement/prospectus.

The foregoing historical financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“U.S. GAAP”). The unaudited pro forma condensed combined financial data have been prepared based on the aforementioned historical financial statements and the assumptions and adjustments as described in the notes to the unaudited pro forma condensed combined financial data. The pro forma adjustments reflect transaction accounting adjustments related to the mergers

TABLE OF CONTENTS

and the forward sale agreements, all of which are discussed in further detail below. Amounts presented reflect the accounting for the acquisition of Bremer by Old National. The unaudited pro forma condensed combined financial data is presented for illustrative purposes only and does not purport to represent the combined company’s consolidated results of operations or consolidated financial position that would actually have occurred had the mergers been consummated and the forward sale agreements been fully physically settled on the dates assumed or to project the combined company’s consolidated results of operations or consolidated financial position for any future date or period.

The unaudited pro forma condensed combined financial data appearing below also does not consider any potential effects of changes in market conditions, certain asset dispositions, cost savings, or revenue synergies, among other factors discussed in the sections entitled “Cautionary Statement Regarding Forward-Looking Statements” and “Risk Factors” and, accordingly, does not attempt to predict or suggest future results. In addition, as explained in more detail in the accompanying notes, the preliminary allocation of the pro forma purchase price reflected in the unaudited pro forma condensed combined financial data is subject to adjustment and may vary significantly from the actual purchase price allocation that will be recorded upon consummation of the mergers.

Accounting for the Mergers

The acquisition of Bremer will be accounted for using the acquisition method of accounting. The total purchase price will be allocated to the tangible and intangible assets and liabilities acquired based on their respective fair values. The allocation of the purchase price reflected in the following unaudited pro forma condensed combined financial data is preliminary and is subject to adjustment upon receipt of, among other things, appraisals of some of the assets and liabilities of Bremer. Upon consummation of the mergers, a final determination of the fair values of Bremer assets acquired and liabilities assumed will be performed. Any changes in the fair values of the net assets or total purchase price as compared with the information shown in the unaudited pro forma condensed combined financial data may change the amount of the total purchase consideration allocated to goodwill, deferred taxes, and other assets and liabilities, and may impact the combined company’s statement of income.

Forward Sale Agreements

In connection with the forward sale agreements, the forward purchaser or its affiliate borrowed from third parties an aggregate of 21,904,762 shares of Old National common stock. The forward sale agreements are classified as equity instruments under ASC 815-40 Contracts in Entity’s Own Equity.

Old National expects to physically settle the forward sale agreements at the offering size of $460.0 million (by the delivery of shares of Old National common stock) and receive proceeds from the sale of those shares of Old National common stock upon one or more forward settlement dates within approximately 12 months from the date of the forward sale agreements. Old National may also elect cash settlement or net share settlement for all or a portion of Old National’s obligations under the forward sale agreements. If Old National elects to cash settle or net share settle the forward sale agreements, then Old National may not receive any proceeds from the issuance of shares of Old National common stock in respect of the forward sale agreements, and Old National will instead receive or pay cash (in the case of cash settlement) or receive or deliver shares of Old National common stock (in the case of net share settlement).

Basis of Pro Forma Presentation

The historical financial data of Old National and Bremer have been adjusted to give pro forma effect to the transaction accounting required for the mergers and the forward sale agreements. The adjustments in the unaudited pro forma condensed combined financial data have been identified and presented to provide relevant information necessary to evaluate the financial overview of the combined company upon closing of the mergers and full physical settlement of the forward sale agreements.

The unaudited pro forma condensed combined financial data is not necessarily indicative of what the combined company’s balance sheet or statement of income would have been had the mergers been completed and the forward sale agreements been fully physically settled as of the dates indicated, nor do they purport to project the future financial position or operating results of the combined company. The unaudited

TABLE OF CONTENTS

pro forma condensed combined financial data is presented for illustrative purposes only and does not reflect the costs of any integration activities or cost savings or synergies that may be achieved because of the mergers. Bremer and Old National have not had any historical material relationship before the mergers. Accordingly, no pro forma adjustments were required to eliminate activities among the companies.

NOTES TO UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS

(Dollars in thousands, except per share data)

Note 1 — Basis of Presentation

The pro forma condensed combined financial information and explanatory notes have been prepared to illustrate the effects of the mergers under the acquisition method of accounting with Old National as the acquirer. The pro forma condensed combined financial information is presented for illustrative purposes only and does not necessarily indicate the financial condition or results of operations of Old National had the companies been combined and had the forward sale agreements been physically settled at the beginning of each period presented, nor does it necessarily indicate the results of operations in future periods or the future financial position of Old National following the mergers. Under the acquisition method of accounting, the assets and liabilities of Bremer, as of the effective time of the mergers, will be recorded by Old National in most cases at their respective fair values and the excess of the merger consideration over the fair value of Bremer’s net assets will be allocated to goodwill.

In connection with the mergers, which are currently expected to be completed in the middle of 2025 subject to the satisfaction of customary closing conditions, each share of Bremer common stock issued and outstanding immediately prior to the effective time (except for dissenting shares, shares of treasury stock or shares owned by Bremer, Old National or ONB Merger Sub, in each case other than shares held in trust accounts, managed accounts, mutual funds and the like, or otherwise held in a fiduciary or agency capacity that are beneficially owned by third parties, or held, directly or indirectly as a result of debts previously contracted) will be converted into the right to receive (i) $26.22 in cash without interest, and (ii) 4.182 shares Old National common stock, valuing merger consideration payable to holders of Bremer common stock at approximately $1.5 billion based on the closing stock price of Old National common stock of $23.58 as of January 28, 2025 on the NASDAQ Stock Exchange.

The pro forma allocation of the purchase price reflected in the unaudited pro forma condensed combined financial information is subject to adjustment and may vary from the actual purchase price allocation that will be recorded at the effective time of the mergers. Adjustments may include, but not be limited to, changes in (i) Bremer’s balance sheet through the effective time; (ii) the aggregate value of merger consideration paid if the price of shares of Old National common stock varies from the assumed $23.58 per share; and (iii) the underlying values of assets and liabilities if market and credit conditions differ from current assumptions.

Note 2 — Preliminary Purchase Price Allocation

The following table summarizes the estimated total purchase price with a sensitivity analysis assuming a 10% increase and 10% decrease in the price per share of Old National common stock from the baseline price, which is the closing price of Old National common stock reported on the NASDAQ Stock Exchange as of January 28, 2025, with its impact on the preliminary goodwill.

In accordance with Section 302A.436 of the MBCA, Bremer shareholders, including holders of Bremer 401(k) Plan shares and Bremer ESOP shares, that have previously consented to receive notice of Bremer shareholder meetings and related materials via electronic communication will receive the notice of the special meeting and this proxy statement/prospectus via such electronic communication and will not receive a hard copy of this proxy statement/prospectus. All other Bremer shareholders, including holders of Bremer 401(k) Plan shares and Bremer ESOP shares, will receive a hard copy of the notice of the special meeting and this proxy statement/prospectus via the mail.

Bremer requests that holders of Bremer common stock vote by telephone, over the Internet or, if you receive a hard copy of this proxy statement/prospectus, by completing and signing the accompanying proxy card and returning it to Bremer as soon as possible in the enclosed postage-paid envelope. When the accompanying proxy card is returned properly executed, the shares of Bremer common stock represented by it will be voted at the special meeting in accordance with the instructions contained on the proxy card. If you make no specification on your proxy card as to how you want your shares voted before signing and returning it, your proxy will be voted “FOR” the merger proposal and “FOR” the adjournment proposal.

If you hold Bremer 401(k) Plan shares or Bremer ESOP shares, you must separately vote your holdings in each plan. You may vote the Bremer 401(k) Plan shares and Bremer ESOP shares by telephone, via the Internet or, if you receive a hard copy of this proxy statement/prospectus, by mail by completing, signing, dating and returning the accompanying voting instruction card for these shares in the enclosed postage-paid return envelope as described on the voting instruction card for each plan.

The deadline for providing these instructions is 10:59 p.m. Central Time on March 3, 2025, which is 72 hours earlier than the deadline to vote any Bremer common stock that you hold in your name as a shareholder of record. This deadline differs because your voting instructions for the Bremer 401(k) Plan shares and the Bremer ESOP shares will be sent confidentially to the independent trustee for the plans, GreatBanc, which will vote these shares on behalf of plan participants in accordance with each plan participant’s voting instructions or as otherwise required consistent with its fiduciary duties to plan participants under applicable law.

Every vote is important.

Sending in your proxy card or voting by telephone or on the Internet will not prevent you from voting your shares at the meeting because you may subsequently revoke your proxy.

THE MERGERS

Terms of the Mergers

Each of the Old National board of directors and the Bremer board of directors has unanimously approved and adopted the merger agreement. Under the merger agreement, ONB Merger Sub will first merge with and into Bremer, with Bremer as the surviving corporation in the first step merger as a wholly-owned subsidiary of Old National. Immediately following the first step merger, and as part of a single, integrated transaction, Bremer will then merge with and into Old National, with Old National as the surviving corporation in the second step merger. Immediately following the second step merger, or at a later time as determined by Old National, Bremer’s wholly-owned banking subsidiary, Bremer Bank, a national banking association, will merge with and into Old National’s wholly-owned banking subsidiary, Old National Bank, a national banking association, with Old National Bank as the surviving bank.

Under the terms and subject to the conditions set forth in the merger agreement, Bremer shareholders will receive cash and Old National common stock for each of their shares of Bremer common stock. At the effective time of the first step merger, each outstanding share of Bremer common stock (except for dissenting shares, shares of treasury stock or shares owned by Bremer, Old National or ONB Merger Sub, in each case other than shares held in trust accounts, managed accounts, mutual funds and the like, or otherwise held in a fiduciary or agency capacity that are beneficially owned by third parties, or held, directly or indirectly, as a result of debts previously contracted) will be converted into the right to receive (i) $26.22 in cash without interest and (ii) 4.182 shares of Old National common stock. No fractional shares of Old National common stock will be issued in the mergers and holders of Bremer common stock will be entitled to receive cash in lieu of fractional shares.

Based on the number of shares of Bremer common stock outstanding as of the date of the merger agreement, Old National expects to issue approximately 50.2 million shares of Old National common stock to Bremer shareholders upon consummation of the mergers, which will result in current Bremer shareholders owning approximately 13.59% of outstanding Old National common stock.

The mergers cannot be completed unless the merger agreement is approved and adopted by the affirmative vote of a majority of the voting power of all shares of Bremer common stock entitled to vote thereon. The closing of the mergers is also subject to the receipt of approvals of the Federal Reserve and the OCC, and the satisfaction of the other conditions specified in the merger agreement.

Bremer Litigation with the Otto Bremer Trust

In November 2019, Bremer initiated litigation against the trustees of the Otto Bremer Trust relating to the validity of the Otto Bremer Trust’s October 2019 sales of Bremer Class B common stock, which we refer to as the “October 2019 share sales”. The trustees of the Otto Bremer Trust filed counterclaims against certain Bremer executives and directors alleging breaches of fiduciary duty and seeking damages. In addition to the claims and counterclaims in Minnesota state court in the initial matter relating to the October 2019 share sales, captioned Bremer Financial et al. v. S. Brian Lipschultz et al., Court File No. 62-CV-19-8203, related claims were brought in Minnesota state court in 2020 by certain shareholders of Bremer in the matter captioned Ronald E. Hansen et al. v. S. Brian Lipschultz et al., Court File No. 62-CV-20-159, and in 2021 by Bremer in the matter captioned Bremer Financial Corporation v. S. Brian Lipschultz et al., Court File No. 62-CV-21-825. In addition, in July 2023, the trustees of the Otto Bremer Trust filed a petition in Minnesota

TABLE OF CONTENTS

state court seeking, among other things, an order approving, confirming and ratifying the October 2019 share sales, to which Bremer and certain of its shareholders initially objected.

On July 23, 2024, Bremer, the Otto Bremer Trust and the other parties to the applicable disputes described above reached an agreement to end all litigation between them. Each of the matters described above was dismissed or withdrawn, as applicable, and Bremer and the Otto Bremer Trust announced that in connection with the resolution of the disputes, two of the trustees of the Otto Bremer Trust would join the Bremer board of directors and the parties would work together to redefine the relationship between the Otto Bremer Trust and Bremer. The agreement was memorialized in a settlement agreement entered into on August 2, 2024, which provided for the formation of a transaction working group (the “working group”) comprised of representatives of the Bremer board of directors and the trustees of the Otto Bremer Trust and their designees.

Background of the Mergers

As described under the section “— Bremer Litigation with the Otto Bremer Trust”, following the August 2, 2024 settlement, a transaction working group was established and charged with the goal of developing and recommending to the Bremer board of directors and the trustees of the Otto Bremer Trust a plan for separating the Otto Bremer Trust and Bremer. In accordance with the August 2, 2024 settlement agreement, J.P. Morgan was engaged as financial advisor to Bremer and Keefe, Bruyette and Woods, Inc. (“KBW”) was engaged as financial advisor to the trustees of the Otto Bremer Trust. Bremer and the trustees of the Otto Bremer Trust selected these advisors for a number of reasons, including J.P. Morgan’s and KBW’s respective investment banking experience and familiarity with the industry in which Bremer operates.

Following its formation, the working group met regularly with members of Bremer’s senior management and representatives of J.P. Morgan, KBW and Wachtell, Lipton, Rosen & Katz (“Wachtell Lipton”), Bremer’s legal advisor. Members of the working group reported to and discussed with the Bremer board of directors the working group’s activities at each subsequent board meeting. The Otto Bremer Trust also discussed the separation planning with its legal advisor, Sullivan & Cromwell LLP.

At the August 30, 2024 meeting of the working group, representatives of J.P. Morgan and KBW reviewed with the working group preliminary information regarding financial analyses of a potential transaction across multiple interest rate scenarios. Representatives of the financial advisors also discussed with the working group certain potentially interested counterparties if the working group were to determine to pursue a strategic business combination. Following extensive discussion, at the conclusion of the August 30, 2024 meeting, the working group requested that J.P. Morgan and KBW solicit and engage in preliminary discussions with certain counterparties regarding a potential strategic transaction.

As requested by the working group, during the first week of September 2024, J.P. Morgan and KBW contacted 12 potential counterparties, including Old National, to gauge their interest in a potential strategic transaction with Bremer. Of the 12 parties contacted, five such parties, including Old National, entered into customary mutual confidentiality agreements with Bremer. The mutual confidentiality agreements did not contain any standstill provisions, and Bremer did not enter into any exclusivity arrangements with any potential counterparty throughout the transaction process.

On September 11, 2024, the Bremer board of directors held a meeting, which was attended by members of Bremer’s senior management and representatives of J.P. Morgan, KBW and Wachtell Lipton. At this meeting, representatives of J.P. Morgan and KBW discussed with the Bremer board of directors the working group’s process to date, including the potential counterparties contacted, the entry into confidentiality agreements with certain potentially interested parties and a summary of the proposed diligence process. Following discussion, the Bremer board of directors directed Bremer’s senior management, J.P. Morgan and KBW to provide potential counterparties with preliminary due diligence information and seek proposals for a strategic business combination transaction.

Following the September 11, 2024 board meeting, at the instruction of the Bremer board of directors, J.P. Morgan and KBW provided the potential counterparties who had entered into confidentiality agreements with a process letter from Bremer, which, among other things, requested that each of the potential counterparties submit its written nonbinding proposal for a potential strategic transaction with Bremer.

TABLE OF CONTENTS

Bremer also granted the counterparties access to an electronic data room containing preliminary due diligence information on Bremer and its subsidiaries. In the weeks that followed, representatives of Bremer senior management, J.P. Morgan, KBW and Wachtell Lipton engaged in discussions and provided responsive due diligence information to potential counterparties. The electronic data room was iteratively updated with additional due diligence information throughout the ensuing transaction process.

On September 25, 2024, Old National submitted a non-binding indication of interest in which it proposed to acquire Bremer in a cash and stock transaction in which Bremer shareholders would receive $10.12 in cash and 5.630 shares of Old National common stock per share of Bremer common stock. Based on the closing price of Old National common stock on September 24, 2024, Old National’s indication of interest represented an implied value of $115.00 per share of Bremer common stock. Old National’s proposal was conditioned on the Otto Bremer Trust, as the holder of 85.96% of the outstanding Bremer common stock, supporting the proposal, including through a voting agreement that would be entered into at announcement of an agreed transaction. In addition to Old National’s proposal, one other financial institution that had entered into a confidentiality agreement with Bremer initially indicated a potential interest in pursuing a strategic transaction, but subsequently withdrew from the transaction process without having ever provided an actionable proposal. None of the other potential counterparties that had entered into confidentiality agreements submitted an indication of interest or other proposal for a strategic transaction with Bremer.

On September 27, 2024, the Bremer board of directors held a meeting with representatives of J.P. Morgan, KBW and Wachtell Lipton in attendance, which included a review of the strategic transaction process and Old National’s preliminary indication of interest. Following discussion, Bremer’s board of directors authorized Bremer’s senior management, with assistance from the outside financial and legal advisors, to continue to advance discussions and the mutual due diligence between Bremer and Old National.

Throughout October and November 2024, members of Bremer senior management and members of Old National senior management, along with representatives of J.P. Morgan, KBW and Old National’s financial advisors, participated in meetings, and the parties exchanged mutual due diligence information.

On October 9, 2024, Bremer’s representatives made available to Old National an initial draft of the merger agreement prepared by Wachtell Lipton.

On November 12, 2024, Old National provided a revised draft of the merger agreement, together with a revised indication of interest in which Old National proposed to acquire Bremer in a cash and stock transaction in which Bremer shareholders would receive $26.22 in cash and 3.962 shares of Old National common stock per share of Bremer common stock. Thereafter, the working group, together with representatives of J.P. Morgan, KBW and Wachtell Lipton, met to review Old National’s revised proposal. Following discussion of the terms of the proposal, the working group directed J.P. Morgan and KBW to seek from Old National a revised proposal that provided for additional consideration to Bremer shareholders, and requested that Bremer’s senior management, with the assistance of J.P. Morgan, KBW and Wachtell Lipton, advance all other aspects of the negotiations and diligence processes so as to enable the working group to make a determination about whether to recommend Old National’s proposed transaction to the Bremer board of directors. Following such meetings, representatives of J.P. Morgan and KBW communicated to representatives of Old National the request for a revised proposal.

Following additional discussions between Bremer, J.P. Morgan, KBW and Wachtell Lipton, on the one hand, and Old National and its advisors, on the other hand, on November 16, 2024, representatives of Old National communicated a revised proposal with enhanced consideration. Under the revised proposal, Bremer shareholders would receive $26.22 in cash and 4.182 shares of Old National common stock per share of Bremer common stock, an increase from the prior proposal of 0.22 shares of Old National common stock per share of Bremer common stock. Bremer and Old National also aligned on a timeline for completing mutual due diligence and finalizing definitive transaction documents, and agreed to work towards announcing a transaction on November 25, 2024.

During the week of November 18, 2024, representatives of Bremer, Old National and the trustees of the Otto Bremer Trust, along with their respective financial and legal advisors, continued to negotiate the merger agreement and ancillary transaction documentation, including the investor agreement (an initial draft

TABLE OF CONTENTS

of which was provided to representatives of Old National by representatives of Bremer on November 19, 2024), the trustee voting agreement (an initial draft of which was provided to representatives of Old National by representatives of Bremer on October 29, 2024) and the director voting agreements (an initial draft of which was provided to representatives of Bremer by representatives of Old National on November 22, 2024), and engaged in continued discussions regarding due diligence and other matters related to the potential transaction.

On November 21, 2024, the working group held a meeting, which was also attended by representatives of J.P. Morgan, KBW and Wachtell Lipton. At the meeting, representatives of J.P. Morgan and KBW reviewed with the working group Old National’s revised proposal of $26.22 in cash and 4.182 shares of Old National common stock per share of Bremer common stock, and representatives of Wachtell Lipton summarized the latest terms and conditions of the transaction agreements. The working group and the advisors discussed various aspects of the Old National proposal, including with respect to the implied valuation of Bremer, the relative proportions of cash and stock consideration proposed, transaction rationale and strategy, corporate culture, the anticipated regulatory approval process and the impact on Bremer employees and communities, including the availability of banking services in underserved rural communities in Bremer’s footprint. Following this discussion, the members of the working group, including each of the representatives of the Otto Bremer Trust, unanimously determined to recommend to Bremer’s board of directors that Bremer pursue the proposed transaction with Old National.

Later on November 21, 2024, the Bremer board of directors held a special meeting, which was attended by representatives of Bremer senior management, J.P. Morgan, KBW and Wachtell Lipton. At this meeting, members of Bremer senior management, the financial advisors and Wachtell Lipton provided an update on the proposed transaction with Old National, including the results of the due diligence process and the unanimous recommendation of the working group that Bremer pursue the proposed transaction with Old National. Representatives of J.P. Morgan reviewed with the Bremer board of directors J.P. Morgan’s preliminary analyses of Old National’s revised proposal. Representatives of Wachtell Lipton also reviewed the fiduciary duties of the directors in the context of the transaction and summarized the key terms of the latest drafts of the merger agreement and other transaction documents. The Bremer board of directors and the advisors discussed various aspects of the proposed transaction, including with respect to the implied valuation of Bremer, the relative proportions of cash and stock consideration proposed, transaction rationale and strategy, corporate culture, the anticipated regulatory approval process and the impact on Bremer employees and communities, including the availability of banking services in underserved rural communities in Bremer’s footprint. Following an extensive discussion, the Bremer board of directors indicated it was supportive of the proposed transaction on the terms discussed, and authorized Bremer senior management to continue to work with Bremer’s legal advisor to finalize the transaction documentation.

During the period from November 21 through November 24, representatives of Bremer, Old National and the Otto Bremer Trust and their respective legal advisors worked to finalize the merger agreement and related transaction documentation, including the investor agreement, the trustee voting agreement and the director voting agreements.

On November 24, 2024, the Bremer board of directors held a special meeting to consider the final negotiated terms of the proposed transaction and entry into the merger agreement. Members of Bremer senior management and representatives of J.P. Morgan, KBW and Wachtell Lipton were also present at the meeting. At this meeting, representatives of J.P. Morgan reviewed with the Bremer board of directors J.P. Morgan’s financial analysis of the potential transaction based on the revised Old National proposal of $26.22 in cash and 4.182 shares of Old National common stock per share of Bremer common stock. Representatives of Wachtell Lipton reviewed the final terms of the merger agreement and the other transaction documentation and reviewed the fiduciary duties of the directors in the context of the transaction, as they had previously done. Representatives of Wachtell Lipton also outlined the proposed resolutions that the Bremer board of directors would be asked to adopt if it were to approve the proposed transaction. Following extensive discussion and questions and answers, J.P. Morgan rendered its oral opinion to the Bremer board of directors, which was subsequently confirmed by delivery of a written opinion, dated November 24, 2024, to the effect that, as of the date of such opinion and based upon and subject to the factors and assumptions made, procedures followed, matters considered and limitations and qualifications set forth in such opinion, the merger consideration to be paid to the holders of Bremer common stock in the

TABLE OF CONTENTS

first step merger was fair, from a financial point of view, to such holders. See the section entitled “— Opinion of Bremer’s Financial Advisor” for more information. After considering the proposed terms of the merger agreement and the mergers and the various presentations made to the Bremer board of directors by Bremer’s financial and legal advisors, and taking into consideration the matters discussed during the meeting and prior meetings of Bremer’s board of directors, including consideration of the factors described under “— Bremer’s Reasons for the Mergers; Recommendation of Bremer’s Board of Directors”, the Bremer board of directors determined that the merger agreement and the transactions contemplated by the merger agreement are advisable and in the best interests of Bremer and its shareholders and resolved to approve and adopt the merger agreement and the transactions contemplated thereby, including the mergers, to authorize management to execute the merger agreement, to submit the merger agreement to a vote of Bremer shareholders and to recommend to Bremer’s shareholders that they approve the merger agreement.

On November 25, 2024, Bremer and Old National executed the merger agreement, each of the trustees of the Otto Bremer Trust and Old National executed the investor agreement and the trustee voting agreement, and each of the other directors of Bremer and Old National executed a director voting agreement. Prior to the opening of the financial markets, Bremer and Old National issued a joint press release to publicly announce the execution of the merger agreement and Old National held an investor call relating to the announced transaction.

Bremer’s Reasons for the Mergers; Recommendation of Bremer’s Board of Directors

The Bremer board of directors has determined that the merger agreement and the transactions contemplated by the merger agreement, including the mergers, are in the best interests of Bremer and its shareholders. In reaching its determination, the Bremer board of directors consulted with Bremer’s senior management, as well as with Bremer’s financial and legal advisors, and considered numerous factors, including the following material factors:

•

the review undertaken by the Bremer board or directors and the working group, with the assistance of outside financial and legal advisors, and the Bremer board of directors’ firm belief that the mergers with Old National were the best option available to Bremer and its shareholders;

•

the value of the merger consideration to Bremer shareholders, including that Old National had the only actionable proposal following a robust process in which 12 potential counterparties were solicited and five counterparties entered confidentiality agreements, participated in the diligence process and were invited to submit proposals;

•

that the process resulted in a transaction that was agreed by the trustees of the Otto Bremer Trust, and the fact that because the Otto Bremer Trust is the owner of 85.96% of the outstanding Bremer common stock and because Old National’s proposal was conditioned on the Otto Bremer Trust agreeing to the proposal, a transaction would not be achievable without the Otto Bremer Trust’s agreement;

•

a review of the prospects and risks of Bremer continuing to operate as a standalone entity majority owned by the Otto Bremer Trust, challenges accompanying ongoing employee uncertainty and risks of the current and anticipated operating environment;

•

the unanimous recommendation of the working group that Bremer pursue the mergers with Old National;

•

the cash component of the merger consideration, which offers Bremer shareholders the opportunity to realize cash for a portion of the value of their shares of Bremer common stock with immediate certainty of value;

•

the stock component of the merger consideration, which provides Bremer shareholders with a publicly-traded, liquid security and the opportunity to participate as shareholders of Old National in the future earnings, performance and growth opportunities of the combined company, which will be a larger, more diversified banking franchise;

•

the anticipated pro forma financial impact of the mergers on the combined company, including future profitability and the balance sheet and liquidity profile of the combined company;

TABLE OF CONTENTS

•

the business, earnings, financial condition, credit quality, capital levels, management, culture, stock performance and prospects of Old National, taking into account the favorable results of Bremer’s due diligence of Old National and the approximately $444 million of additional common equity raised by Old National substantially concurrently with the announcement of the transaction;

•

the complementary aspects of the businesses and cultures of Bremer and Old National, geographic dispersion of Bremer’s and Old National’s branch offices compared to Bremer’s current branch network, business lines and compatibility of management philosophies with respect to credit quality and commitment to community banking in underserved rural markets;

•

that Bremer and Old National have comparable reputations in their respective markets for operating with a relationship-based philosophy and culture;

•

Old National’s record of service and long-term commitment to its communities;

•

the likelihood that the regulatory approvals necessary to complete the mergers would be obtained;

•

the fact that Old National is an experienced acquiror and has a history of successfully obtaining regulatory clearances for, and integrating, strategic transactions;

•

the ability of the Bremer board of directors to change its recommendation that Bremer shareholders vote in favor of approval of the merger agreement, subject to the terms and conditions set forth in the merger agreement and that in the event of such recommendation change, the voting agreements will be automatically terminated and the trustees of the Otto Bremer Trust and the directors subject to the voting agreements will be released from their obligation to vote in favor of approval and adoption of the merger agreement;

•

the financial analyses presented by J.P. Morgan and the oral opinion of J.P. Morgan, dated November 24, 2024, to the Bremer board of directors, which was subsequently confirmed by delivery of a written opinion, dated November 24, 2024, to the effect that, as of the date of such opinion and based upon and subject to the factors and assumptions made, procedures followed, matters considered, and limitations and qualifications set forth in such opinion, the merger consideration to be paid to the holders of Bremer common stock in the mergers was fair, from a financial point of view, to such holders, as more fully described below under the section entitled “Opinion of Bremer’s Financial Advisor” and the full text of such opinion is attached to this proxy statement/prospectus as Annex D; and

•

the terms of the merger agreement, including the limited closing conditions and the expected tax treatment of the mergers, taken together, as a “reorganization” within the meaning of Section 368(a) of the Code for United States federal income tax purposes.

The Bremer board of directors also considered a variety of risks and other potentially negative factors concerning the mergers, including the following material factors:

•

that the exchange ratio for the stock portion of the merger consideration is fixed, so that if the market price of Old National common stock is lower at the time of the closing of the mergers, the economic value of the per share merger consideration to be received by Bremer’s shareholders in exchange for their shares of Bremer common stock will also be lower;

•

the possibility that the mergers and the related integration process could result in the loss of key employees, in the disruption of Bremer’s ongoing business and in the loss of customers for the combined company;

•

the fact that there can be no assurance that all conditions to the parties’ obligations to complete the mergers will be satisfied, including the risk that certain regulatory approvals, the receipt of which is a condition to the consummation of the mergers, might not be obtained, and, as a result, that the mergers might not be consummated or may be subject to delay;

•

the fact that Bremer’s officers and employees would have to focus on actions required to complete the mergers, which would divert their attention from Bremer’s day-to-day business, and that Bremer will incur substantial transaction costs even if the mergers are not consummated;

•

the risk that potential benefits sought in the mergers might not be realized or might not be realized within the expected time period, and the risks associated with the integration of the two companies;

TABLE OF CONTENTS

•

the restrictions on the conduct of Bremer’s business prior to the completion of the mergers, which are customary for merger agreements involving financial institutions;

•

the fact that the merger agreement includes certain provisions that prohibit Bremer from soliciting alternative transactions and from taking certain actions in response to unsolicited proposals for alternative transactions;

•

Bremer’s obligation to pay Old National a termination fee of $55 million in certain circumstances and discussed further under the section titled “The Merger Agreement—Termination Fee”; and

•

the interests of certain of Bremer’s directors and executive officers in the mergers that are different from or in addition to those of Bremer shareholders generally, as more fully described under the section titled “— Interests of Bremer’s Directors and Executive Officers in the Mergers.”

In reaching its conclusion, the Bremer board of directors did not find it practical to assign, and did not assign, any relative or specific weight to the different factors that were considered, and individual members of the Bremer board of directors may have given different weight to different factors. The Bremer board of directors considered all of the information and factors presented, including the potential risks, uncertainties, advantages and disadvantages associated with the mergers, in the aggregate rather than separately, and determined the benefits of the mergers to outweigh the potential risks, uncertainties, and disadvantages associated with the mergers and to be favorable to and support its determination.

This explanation of the reasoning of the Bremer board of directors and all other information presented in this section are forward-looking in nature and should be read in light of the factors set forth in the section entitled “Cautionary Statement Regarding Forward-Looking Statements.”

For the reasons set forth above, the Bremer board of directors unanimously recommends that Bremer shareholders vote “FOR” the merger proposal.

Opinion of Bremer’s Financial Advisor

Bremer retained J.P. Morgan to act as its financial advisor in connection with the mergers. At the meeting of the Bremer board of directors on November 24, 2024, J.P. Morgan rendered its oral opinion to the Bremer board of directors, which was subsequently confirmed in writing on November 24, 2024, to the effect that, as of such date and based upon and subject to the factors and assumptions made, procedures followed, matters considered, and limitations and qualifications set forth in its opinion, the merger consideration to be paid to Bremer shareholders in the first step merger was fair, from a financial point of view, to such holders.

The full text of the written opinion of J.P. Morgan, dated November 24, 2024, which sets forth, among other things, the assumptions made, procedures followed, matters considered and qualifications and limits on the review undertaken by J.P. Morgan in rendering its fairness opinion, is attached as Annex D to this proxy statement/prospectus and is incorporated herein by reference. The summary of the opinion of J.P. Morgan set forth in this proxy statement/prospectus is qualified in its entirety by reference to the full text of such opinion. Bremer shareholders are urged to read the opinion in its entirety. J.P. Morgan’s written opinion was addressed to the Bremer board of directors (in its capacity as such) in connection with and only for the purposes of its evaluation of the mergers, was directed only to the consideration to be paid to the Bremer shareholders and did not address any other aspect of the mergers. J.P. Morgan expressed no opinion as to the fairness of the consideration to the holders of any other class of securities, creditors or other constituencies of Bremer or as to the underlying decision by Bremer to engage in the proposed mergers. The issuance of J.P. Morgan’s opinion was approved by a fairness committee of J.P. Morgan. The opinion does not constitute a recommendation to any Bremer shareholder as to how such Bremer shareholder should vote with respect to the proposed mergers or any other matter.

In arriving at its opinion, J.P. Morgan, among other things:

•

reviewed a draft dated November 24, 2024 of the merger agreement;

•

reviewed certain publicly available business and financial information concerning Bremer and Old National and the industries in which they operate;

TABLE OF CONTENTS

•

compared the financial and operating performance of Bremer and Old National with publicly available information concerning certain other companies J.P. Morgan deemed relevant and reviewed the current and historical market prices of Old National common stock and certain publicly traded securities of such other companies;

•

reviewed certain internal financial analyses and forecasts prepared by the management of Bremer relating to the business of Bremer, certain financial analyses and forecasts relating to the business of Old National, which were approved by Bremer for use in connection with J.P. Morgan’s opinion, as well as the estimated amount and timing of the cost savings and related expenses and synergies expected to result from the mergers (the “Synergies”); and

•

performed such other financial studies and analyses and considered such other information as J.P. Morgan deemed appropriate for the purposes of its opinion.

In addition, J.P. Morgan held discussions with certain members of the management of Bremer and Old National with respect to certain aspects of the mergers, and the past and current business operations of Bremer and Old National, the financial condition and future prospects and operations of Bremer and Old National, the effects of the mergers on the financial condition and future prospects of Bremer and Old National and certain other matters J.P. Morgan believed necessary or appropriate to its inquiry.

In giving its opinion, J.P. Morgan relied upon and assumed the accuracy and completeness of all information that was publicly available or was furnished to or discussed with J.P. Morgan by Bremer and Old National or otherwise reviewed by or for J.P. Morgan. J.P. Morgan did not independently verify any such information or its accuracy or completeness and, pursuant to its engagement letter with Bremer, did not assume any obligation to undertake any such independent verification. J.P. Morgan did not conduct and was not provided with any valuation or appraisal of any assets, liabilities or allowances for loan and lease losses, nor did J.P. Morgan evaluate the solvency of Bremer, Old National or ONB Merger Sub under any state or federal laws relating to bankruptcy, insolvency or similar matters. J.P. Morgan is not an expert in evaluating the adequacy of allowances for loan and lease losses of Bremer or Old National with respect to their loan and lease portfolios and, accordingly J.P. Morgan did not make an independent evaluation of the adequacy of allowances for loan and lease losses of Bremer or Old National with respect to their loan and lease portfolios and assumed, with Bremer’s consent, that the respective allowances for loan and lease losses for both Bremer and Old National were adequate to cover such losses and will be adequate on a pro forma basis for the combined entity. In relying on financial analyses and forecasts provided to J.P. Morgan or derived therefrom, including the Synergies, J.P. Morgan assumed that they were reasonably prepared based on assumptions reflecting the best currently available estimates and judgments by Bremer management as to the expected future results of operations and financial condition of Bremer and Old National to which such analyses or forecasts relate. J.P. Morgan expressed no view as to such analyses or forecasts (including the Synergies) or the assumptions on which they were based. In addition, J.P. Morgan assumed, with Bremer’s consent, that Old National’s proposed issuance of approximately $400 million of additional equity securities to certain investors would be consummated on the terms and conditions and in the time frame described by Bremer management (which terms and conditions included a $60 million greenshoe and a $16 million underwriting spread resulting in net cash proceeds to Old National of $444 million assuming full exercise of the greenshoe (such issuance of equity securities, the “Capital Raise”)). J.P. Morgan also assumed that the mergers and the other transactions contemplated by the merger agreement will qualify as a tax-free reorganization for United States federal income tax purposes and will be consummated as described in the merger agreement, and that the definitive merger agreement would not differ in any material respects from the draft thereof furnished to J.P. Morgan. J.P. Morgan also assumed that the representations and warranties made by Bremer, Old National and ONB Merger Sub in the merger agreement and the related agreements were and will be true and correct in all respects material to J.P. Morgan’s analysis. J.P. Morgan is not a legal, regulatory or tax expert and has relied on the assessments made by advisors to Bremer with respect to such issues. J.P. Morgan further assumed that all material governmental, regulatory or other consents and approvals necessary for the consummation of the mergers will be obtained without any adverse effect on Bremer or Old National or on the contemplated benefits of the mergers.

The Bremer management projections (as defined in the section entitled “— Certain Unaudited Prospective Financial Information”) furnished to J.P. Morgan were prepared by or at the direction of the

TABLE OF CONTENTS

management of Bremer, as discussed more fully under the section entitled “— Certain Unaudited Prospective Financial Information.” Bremer does not publicly disclose internal management projections of the type provided to J.P. Morgan in connection with J.P. Morgan’s analysis of the mergers, and such projections were not prepared with a view toward public disclosure. The Bremer management projections were based on numerous variables and assumptions that are inherently uncertain and may be beyond the control of the management of Bremer, including, without limitation, factors related to general economic and competitive conditions and prevailing interest rates. Accordingly, actual results could vary significantly from those set forth in such projections. For more information regarding the use of projections and other forward-looking statements, please refer to the section entitled “— Certain Unaudited Prospective Financial Information.”

J.P. Morgan’s opinion was necessarily based on economic, market and other conditions as in effect on, and the information made available to J.P. Morgan as of, the date of such opinion. J.P. Morgan’s opinion noted that subsequent developments may affect J.P. Morgan’s opinion, and that J.P. Morgan does not have any obligation to update, revise, or reaffirm such opinion. J.P. Morgan’s opinion is limited to the fairness, from a financial point of view, of the merger consideration to be paid to Bremer shareholders in the first step merger and J.P. Morgan expressed no opinion as to (i) the fairness of any consideration to be paid in connection with the first step merger to the holders of any other class of securities, creditors or other constituencies of Bremer, (ii) the allocation of the aggregate consideration to be paid to all Bremer shareholders between the holders of Bremer Class A common stock and Bremer Class B common stock, or the relative fairness of the consideration to the holders of any shares of Bremer common stock, or (iii) as to the underlying decision by Bremer to engage in the mergers. J.P. Morgan also did not express any opinion as to the trustee voting agreement or the director voting agreements or any voting, governance or other rights of the Otto Bremer Trust, whether pursuant thereto or otherwise (and did not take any such rights into account in its analysis). Furthermore, J.P. Morgan expressed no opinion with respect to the amount or nature of any compensation to any officers, directors, or employees of any party to the mergers, or any class of such persons relative to the merger consideration to be paid to Bremer shareholders in the first step merger or with respect to the fairness of any such compensation. J.P. Morgan expressed no opinion as to the price at which Old National common stock will trade at any future time.

The terms of the merger agreement, including the merger consideration, were determined through arm’s-length negotiations between Bremer and Old National, and the decision to enter into the merger agreement was solely that of Bremer’s board of directors. J.P. Morgan’s opinion and financial analyses were only one of the many factors considered by Bremer’s board of directors in its evaluation of the proposed mergers and should not be viewed as determinative of the views of Bremer’s board of directors or management with respect to the proposed mergers or the merger consideration.

In accordance with customary investment banking practice, J.P. Morgan employed generally accepted valuation methodology in rendering its opinion to Bremer’s board of directors on November 24, 2024 and contained in the presentation delivered to Bremer’s board of directors on such date in connection with the rendering of such opinion. The summary below does not purport to be a complete description of the analyses or data presented by J.P. Morgan. Some of the summaries of the financial analyses include information presented in tabular format in the section entitled “— Other Analyses — Cash-Adjusted Implied Relative Value Analysis.” The tables are not intended to stand alone, and in order to more fully understand the financial analyses used by J.P. Morgan, the tables must be read together with the full text of each summary. Considering the data set forth below without considering the full narrative description of the financial analyses, including the methodologies and assumptions underlying the analyses, could create a misleading or incomplete view of J.P. Morgan’s analyses.

Bremer Analyses

Public Trading Multiples Analysis

For purposes of its public trading multiples analysis, and using publicly available information, J.P. Morgan compared selected financial data of Bremer with similar data for four selected publicly traded companies engaged in businesses that J.P. Morgan judged to be analogous to Bremer’s businesses. The companies selected by J.P. Morgan were:

TABLE OF CONTENTS

Brookline Bancorp, Inc.;

Dime Community Bancshares, Inc.;

Horizon Bancorp, Inc.; and

Metropolitan Bank Holding Corp. (collectively, the “Bremer selected companies”).

The Bremer selected companies were selected by J.P. Morgan because of similarities to Bremer in one or more of their business characteristics and, in certain cases, similarities to Bremer based on certain operational characteristics and/or certain financial metrics. However, none of the Bremer selected companies is identical or directly comparable to Bremer, and certain of the companies may have characteristics that are materially different from those of Bremer. Accordingly, a complete analysis of the results of the following calculations cannot be limited to a quantitative review of such results and involves complex considerations and judgments concerning the differences in the financial and operating characteristics of the Bremer Selected Companies compared to Bremer and other factors that could affect the public trading value of the Bremer Selected Companies and the value of Bremer.

Multiples were based on closing stock prices on November 22, 2024, which was the last practicable date prior to the delivery of J.P. Morgan’s opinion. Financial and market data and earnings per share estimates for the Bremer selected companies were based on such companies’ respective public filings and information J.P. Morgan obtained from FactSet Research Systems and S&P Global Market Intelligence. The multiples for each of the Bremer Selected Companies were based on the most recent publicly available information.

J.P. Morgan’s public trading multiples analysis was based on the Bremer Selected Companies. J.P. Morgan’s presentation included the multiple of each Bremer selected company’s share price to its estimated earnings per share for fiscal year 2025 (Price/2025E EPS). Based on the results of this analysis and other factors which J.P. Morgan considered appropriate based on its experience and judgement, J.P. Morgan selected a range of Price/2025E EPS multiples of 9.2x to 12.9x. J.P. Morgan applied this reference multiple range to Bremer management’s estimate of Bremer’s estimated earnings per share for fiscal year 2025, as provided in the Bremer management projections used by J.P. Morgan and described in the section entitled “— Certain Unaudited Prospective Financial Information.” The analysis indicated a range of implied equity values per share of Bremer common stock of $118.25 to $166.55, as compared to the implied value of the consideration per share of Bremer common stock of $116.76 based on the closing price of Old National common stock of $21.65 on November 22, 2024.

Dividend Discount Analysis

J.P. Morgan calculated a range of implied values for Bremer common stock by discounting to present value estimates of Bremer’s future dividend stream and terminal value. In performing its analysis, J.P. Morgan utilized, among others, the following assumptions, which were reviewed and approved (and, in certain cases, provided) by Bremer management:

•

The Bremer management projections;

•

Terminal value based on estimated net income for fiscal year 2029 at a price to next-twelve-months earnings (NTM P/E) multiple range of 9.0x to 11.0x;

•

Cost of equity range of 9.25% to 11.25%; and

•

Common Equity Tier 1 target ratio of 12.5%.

These calculations resulted in a range of implied values of $116.74 to $143.28 per share of Bremer common stock, as compared to the implied value of the consideration per share of Bremer common stock of $116.76 based on the closing price of Old National common stock of $21.65 on November 22, 2024.

Old National Analyses

Public Trading Multiples Analysis

For purposes of its public trading multiples analysis, and using publicly available information, J.P. Morgan compared selected financial data of Old National with similar data for nine selected publicly

TABLE OF CONTENTS

traded companies engaged in businesses that J.P. Morgan judged to be analogous to Old National’s businesses (collectively, referred to in this section as the “Old National selected companies”). The companies selected by J.P. Morgan were:

Associated Banc-Corp;

Banc of California, Inc.;

Cadence Bank;

Columbia Banking System, Inc.;

F.N.B. Corporation;

Fulton Financial Corporation;

Hancock Whitney Corporation;

Prosperity Bancshares, Inc.; and

Synovus Financial Corp.

The Old National selected companies were selected by J.P. Morgan because of similarities to Old National in one or more of their business characteristics and, in certain cases, similarities to Old National based on certain operational characteristics and/or certain financial metrics. However, none of the Old National selected companies is identical or directly comparable to Old National, and certain of the companies may have characteristics that are materially different from those of Old National. Accordingly, a complete analysis of the results of the following calculations cannot be limited to a quantitative review of such results and involves complex considerations and judgments concerning the differences in the financial and operating characteristics of the Old National selected companies compared to Old National and other factors that could affect the public trading value of the Old National selected companies and Old National.

Multiples were based on closing stock prices on November 22, 2024, which was the last trading date prior to the delivery of J.P. Morgan’s opinion. Financial and market data and earnings per share estimates for the Old National selected companies were based on such companies’ respective public filings and information J.P. Morgan obtained from FactSet Research Systems and S&P Global Market Intelligence. The multiples for each of the Old National selected companies were based on the most recent publicly available information.

J.P. Morgan’s presentation included the Price/2025E EPS multiple of each Old National selected company. Based on the results of this analysis and other factors which J.P. Morgan considered appropriate based on its experience and judgement, J.P. Morgan selected a range of Price/2025E EPS multiples of 11.1x to 14.5x. J.P. Morgan applied this reference multiple range to Wall Street equity research consensus estimates of Old National’s earnings per share for fiscal year 2025, based upon the Old National street estimates and projections (as defined in the section entitled “— Certain Unaudited Prospective Financial Information”). The analysis indicated a range of implied equity values per share of Old National common stock of $21.65 to $28.34, as compared to the closing price of Old National common stock of $21.65 on November 22, 2024.

Dividend Discount Analysis

J.P. Morgan calculated a range of implied values for Old National common stock by discounting to present value estimates of Old National’s future dividend stream and terminal value. In performing its analysis, J.P. Morgan utilized, among others, the following assumptions, which were reviewed and approved (and, in certain cases, provided) by Bremer management:

•

Old National street estimates and projections (as defined in the section entitled “— Certain Unaudited Prospective Financial Information”);

•

Terminal value based on estimated net income for fiscal year 2029 at an NTM P/E multiple range of 10.0x to 12.0x;

•

Cost of equity range of 8.50% to 10.50%; and

TABLE OF CONTENTS

•

Common Equity Tier 1 target ratio of 10.0%.

These calculations resulted in a range of implied values of $21.64 to $26.01 per share of Old National common stock, as compared to the closing price of Old National common stock of $21.65 on November 22, 2024.

Other Analyses

Cash-Adjusted Implied Relative Value Analysis

J.P. Morgan compared the results for Bremer to the results for Old National with respect to the public trading multiples and dividend discount analyses described above. J.P. Morgan compared the lowest equity value per share for Bremer (adjusted to reflect Old National’s payment of fixed cash consideration equal to $26.22 per share of Bremer common stock, as contemplated by the merger agreement) to the highest equity value per share for Old National to derive the lowest exchange ratio implied by each pair of results. J.P. Morgan also compared the highest equity value per share for Bremer (adjusted to reflect Old National’s payment of fixed cash consideration equal to $26.22 per share of Bremer common stock, as contemplated by the merger agreement) to the lowest equity value per share for Old National to derive the highest exchange ratio implied by each pair of results. The ranges of implied exchange ratios resulting from this analysis were:

	Implied Exchange Ratios
	Low	High
Price/2025E EPS	3.2472x	6.4818x
Dividend Discount Model	3.4800x	5.4090x

The ranges of implied exchange ratios resulting from the foregoing analysis were compared to the exchange ratio of 4.182x contemplated by the merger agreement.

Value Creation Analysis

Based on the Bremer management projections and information J.P. Morgan obtained from FactSet Research Systems and S&P Global Market Intelligence, J.P. Morgan prepared a value creation analysis that compared the equity value of Bremer to the Bremer shareholders’ portion of the pro forma combined company equity value. J.P. Morgan determined the pro forma combined company equity value by calculating the sum of (i) the equity value of Bremer derived using the midpoint value determined in J.P. Morgan’s dividend discount analysis described above in “— Bremer Analyses — Dividend Discount Analysis” (Bremer’s “Standalone Value”) plus (ii) the equity value of Old National derived using the midpoint value determined in J.P. Morgan’s dividend discount analysis (described above in “— Old National Analyses — Dividend Discount Analysis”) plus (iii) the $444 million net cash proceeds of the Capital Raise minus (iv) the aggregate amount of cash consideration to be paid by Old National to Bremer shareholders pursuant to the merger agreement plus (v) the estimated present value of expected Synergies (using projected Synergy amounts provided by Bremer management, a cost of equity range of 9.25% to 11.25% and a terminal NTM P/E multiple range of 9.0x to 11.0x). There can be no assurance that the Synergies and transaction-related fees and expenses will not be substantially greater or less than the estimate described above. The value creation analysis, at the exchange ratio, yielded accretion to Bremer shareholders of $85 million in aggregate, as compared to Bremer’s Standalone Value.

Other Information

For reference only and not as a component of its fairness analysis, J.P. Morgan also reviewed the following information, among other information:

•

a regression analysis to review the relationship between (i) a multiple of share price to tangible book value per share and (ii) the estimated 2025 return on average tangible common equity, for Bremer, the Bremer Selected Companies and certain other publicly traded companies engaged in businesses that J.P. Morgan judged to be analogous to Bremer’s businesses (namely, (1) Berkshire Hills Bancorp,

TABLE OF CONTENTS

Inc., (2) Enterprise Financial Services Corp, (3) First Financial Bancorp, (4) First Merchants Corporation, (5) Independent Bank Corp. (Massachusetts) and (6) Trustmark Corporation);

•

the historical range of trading prices of Old National common stock for the 52-week period ending November 22, 2024;

•

analyst share price targets for Old National common stock in recently published, publicly available research analysts’ reports, with share price targets ranging from $21.00 to $26.00 and noting a median share price target of $24.00; and

•

Miscellaneous

The foregoing summary of certain material financial analyses does not purport to be a complete description of the analyses or data presented by J.P. Morgan. The preparation of a fairness opinion is a complex process and is not necessarily susceptible to partial analysis or summary description. J.P. Morgan believes that the foregoing summary and its analyses must be considered as a whole and that selecting portions of the foregoing summary and these analyses, without considering all of its analyses as a whole, could create an incomplete view of the processes underlying the analyses and its opinion. As a result, the ranges of valuations resulting from any particular analysis or combination of analyses described above were merely utilized to create points of reference for analytical purposes and should not be taken to be the view of J.P. Morgan with respect to the actual value of Bremer or Old National. The order of analyses described does not represent the relative importance or weight given to those analyses by J.P. Morgan. In arriving at its opinion, J.P. Morgan did not attribute any particular weight to any analyses or factors considered by it and did not form an opinion as to whether any individual analysis or factor (positive or negative), considered in isolation, supported or failed to support its opinion. Rather, J.P. Morgan considered the totality of the factors and analyses performed in determining its opinion.

Analyses based upon forecasts of future results are inherently uncertain, as they are subject to numerous factors or events beyond the control of the parties and their advisors. Accordingly, forecasts and analyses used or made by J.P. Morgan are not necessarily indicative of actual future results, which may be significantly more or less favorable than suggested by those analyses. Moreover, J.P. Morgan’s analyses are not and do not purport to be appraisals or otherwise reflective of the prices at which businesses actually could be acquired or sold. None of the selected companies reviewed as described in the above summary is identical to Bremer or Old National. However, the companies selected were chosen because they are publicly traded companies with operations and businesses that, for purposes of J.P. Morgan’s analysis, may be considered similar to those of Bremer and Old National. The analyses necessarily involve complex considerations and judgments concerning differences in financial and operational characteristics of the companies involved and other factors that could affect the companies compared to Bremer and Old National.

As a part of its investment banking business, J.P. Morgan and its affiliates are continually engaged in the valuation of businesses and their securities in connection with mergers and acquisitions, investments for passive and control purposes, negotiated underwritings, secondary distributions of listed and unlisted securities, private placements, and valuations for corporate and other purposes. J.P. Morgan was selected to advise Bremer with respect to the mergers on the basis of, among other things, such experience and its qualifications and reputation in connection with such matters and its familiarity with Bremer, Old National and the industries in which they operate.

For financial advisory services rendered in connection with the proposed transaction, Bremer has agreed to pay J.P. Morgan a fee of up to approximately $14.0 million, a portion of which became payable to J.P. Morgan upon delivery of its opinion, and the substantial remainder of which is contingent and payable upon the consummation of the mergers. In addition, Bremer has agreed to reimburse J.P. Morgan for its expenses incurred in connection with its services, including the fees and disbursements of counsel, and will indemnify J.P. Morgan against certain liabilities arising out of J.P. Morgan’s engagement. During the two years preceding the date of J.P. Morgan’s opinion, neither J.P. Morgan nor its affiliates have had any other material financial advisory or other material commercial or investment banking relationships with Bremer,

TABLE OF CONTENTS

Bremer’s 85.96% shareholder (the Otto Bremer Trust) or Old National. During the two-year period preceding delivery of its opinion, the aggregate fees recognized by J.P. Morgan from Bremer were approximately $64,000, from Otto Bremer Trust were $0, and from Old National were approximately $14,000. In addition, J.P. Morgan and its affiliates hold, on a proprietary basis, less than 1% of the outstanding Old National common stock. In the ordinary course of their businesses, J.P. Morgan and its affiliates may actively trade the debt and equity securities or financial instruments (including derivatives, bank loans or other obligations) of Bremer or Old National for their own accounts or for the accounts of customers and, accordingly, may at any time hold long or short positions in such securities or other financial instruments.

Certain Unaudited Prospective Financial Information

Old National and Bremer do not, as a matter of course, publicly disclose forecasts or internal projections as to future performance, revenues, earnings, financial condition or other results due to, among other reasons, the inherent uncertainty of the underlying assumptions and estimates. However, in connection with the mergers, Old National and Bremer are including in this proxy statement/prospectus certain limited unaudited prospective financial information for Old National and Bremer (which we refer to collectively as the “projections”), in each case on a standalone basis and without giving effect to the mergers (except as expressly set forth below under “— Certain Estimated Synergies Attributable to the Mergers”). The prospective financial information is included in this proxy statement/prospectus to give Bremer shareholders access to certain information provided to Bremer, Bremer’s board of directors and J.P. Morgan, Bremer’s financial advisor, in connection with the mergers.

The projections were not prepared with a view toward public disclosure. As a result, the inclusion of the projections in this proxy statement/prospectus should not be regarded as an indication that Old National, Bremer or any other recipient of the projections considered, or now considers, them to be necessarily predictive of actual future results, or that they should be construed as financial guidance, and they should not be relied on as such. This information was prepared solely for internal use (other than publicly available consensus Wall Street estimates, or “street estimates”) and is subjective in many respects. The projections were prepared based on the information available to the preparers at the time of their preparation. While presented with numeric specificity, the projections reflect numerous estimates and assumptions made with respect to business, economic, market, competition, regulatory and financial conditions and matters specific to Old National’s and Bremer’s businesses, all of which are difficult to predict and many of which are beyond Old National’s and Bremer’s control. In addition, since the projections cover multiple years, such information by its nature becomes subject to greater uncertainty with each successive year.

The projections also reflect assumptions as to certain business decisions that are subject to change. The projections reflect subjective judgment in many respects and thus are susceptible to multiple interpretations and periodic revisions based on actual experience and business developments. As such, the projections constitute forward-looking information and are subject to risks and uncertainties that could cause actual results to differ materially from the results forecasted in such prospective information, including, but not limited to, Old National’s performance, Bremer’s performance, industry performance, general business and economic conditions, customer requirements, competition, adverse changes in applicable laws, regulations or rules, and the various risks set forth in Old National’s reports filed with the SEC. For other factors that could cause the actual results to differ from the results forecasted in the projections, please see the sections entitled “Risk Factors” and “Cautionary Statement Regarding Forward-Looking Statements” in this proxy statement/prospectus.

The projections were not prepared with a view toward public disclosure or toward complying with GAAP, the published guidelines of the SEC regarding projections or the guidelines established by the American Institute of Certified Public Accountants for preparation and presentation of prospective financial information. None of Deloitte & Touche LLP, the current independent registered public accounting firm to Old National, Crowe LLP, the former independent registered public accounting firm to Old National, Ernst & Young LLP, the independent auditor to Bremer, or any other independent accountants, have audited, reviewed, compiled, examined or performed any procedures with respect to the projections included below, or expressed any opinion or any other form of assurance on such information or its achievability, and assume no responsibility for the projections and disclaim any association with the projections. The reports by Deloitte & Touche LLP and Crowe LLP incorporated by reference in this proxy statement/prospectus relate

TABLE OF CONTENTS

to Old National’s previously issued financial statements. The report by Ernst & Young LLP included in this proxy statement/prospectus relate to Bremer’s previously issued financial statements. The reports by Deloitte & Touche LLP, Crowe LLP and Ernst & Young LLP do not extend to the projections and should not be read to do so. The projections are the responsibility of Bremer management.

Furthermore, the projections do not take into account any circumstances or events occurring after the date they were prepared, including the transactions contemplated by the merger agreement or the possible financial and other effects on Old National or Bremer of the mergers (other than with respect to certain projections related to the combined company set forth under “— Certain Estimated Synergies Attributable to the Mergers” below), and do not attempt to predict or suggest future results of the combined company following the mergers or give effect to the mergers, including the impact of negotiating or executing the merger agreement, the expenses that may be incurred in connection with consummating the mergers, the potential synergies that may be achieved by the combined company as a result of the mergers (except as expressly set forth below under “— Certain Estimated Synergies Attributable to the Mergers”), the effect on Old National or Bremer of any business or strategic decision or action that has been or will be taken as a result of the merger agreement having been executed, or the effect of any business or strategic decisions or actions which would likely have been taken if the merger agreement had not been executed, but which were instead altered, accelerated, postponed or not taken in anticipation of the mergers.

Neither Old National nor Bremer can give any assurance that, had the projections been prepared either as of the date of the merger agreement or as of the date of this proxy statement/prospectus, similar estimates and assumptions would be used. Further, the projections do not take into account the effect of any possible failure of the mergers to occur. None of Old National, Bremer or J.P. Morgan, nor any of their affiliates or representatives, intends to, and each of them disclaims any obligation to, update, revise or correct the projections if they are or become inaccurate (even in the short term). The inclusion of the projections herein should not be deemed an admission or representation by Old National or Bremer that they are viewed by Old National or Bremer as material information of Old National or Bremer, respectively, particularly in light of the inherent risks and uncertainties associated with such projections. None of Old National, Bremer or J.P. Morgan, nor their respective affiliates or representatives, has made, makes or is authorized in the future to make any representation to any shareholder of Old National or Bremer or other person regarding Old National’s or Bremer’s ultimate performance compared to the information contained in the projections or that the forecasted results will be achieved. The projections included below are being provided because they were made available to and considered by J.P. Morgan, Bremer and Bremer’s board of directors in connection with the mergers.

In light of the foregoing, and considering that the special meeting will be held several months after the projections were prepared, as well as the uncertainties inherent in any forecasted information, Bremer shareholders are strongly cautioned not to place unwarranted reliance on such information, and Bremer shareholders are urged to review Old National’s most recent SEC filings and other documents incorporated herein by reference for a description of Old National’s reported financial results and the financial information of Bremer included in this proxy statement/prospectus. See “Where You Can Find More Information.”

Certain Estimated Synergies Attributable to the Mergers

Bremer management developed and provided to its board of directors certain projections relating to the anticipated cost synergies to be realized by the combined company following the completion of the mergers, which we refer to as the “Synergies”. At the direction of Bremer’s board of directors, such projections were also provided by Bremer management to J.P. Morgan and approved by Bremer management for J.P. Morgan’s use and reliance in the financial analyses performed in connection with J.P. Morgan’s opinion as described in this proxy statement/prospectus under the section entitled “— Opinion of J.P. Morgan, Bremer’s Financial Advisor”.

For purposes of its analysis, J.P. Morgan was directed by Bremer management to assume estimated pre-tax annual cost savings of $111 million, phased in 50% in 2025 and 100% thereafter, with a 5% growth in annual cost savings starting in 2027. The total restructuring charge was estimated by Bremer management to be $194 million pre-tax ($153 million after tax), all assumed to be incurred at the closing of the mergers. The Synergies assumed a hypothetical June 30, 2025 closing date for the mergers. See above in this section for further information regarding the uncertainties underlying the synergy assumptions and estimates as well as the sections entitled “Cautionary Statement Regarding Forward-Looking Statements” and “Risk Factors” beginning on pages 16 and 18, respectively, for further information regarding the uncertainties and factors associated with realizing synergies in connection with the mergers.

Interests of Bremer’s Directors and Executive Officers in the Mergers

Under the merger agreement, the directors and executive officers of Bremer will receive the same merger consideration for their shares of Bremer common stock as other Bremer shareholders. In considering the recommendation of the Bremer board of directors that Bremer shareholders vote in favor of the proposal to approve the merger agreement, Bremer shareholders should be aware that the directors and executive officers of Bremer have certain interests in the transactions that are or may be different from, or in addition to, the interests of Bremer shareholders generally. The Bremer board of directors was aware of these interests and considered them, among other matters, in approving the merger agreement and the transactions contemplated by it, and in making their recommendation that Bremer shareholders approve and adopt the merger agreement. For further information, see “The Mergers — Background of the Mergers” and “The Mergers — Bremer’s Reasons for the Mergers; Recommendation of Bremer’s Board of Directors.” These interests are described in more detail below, and certain of them are quantified in the narrative below.

Directors

Shareholder Voting Agreements

In connection with the execution of the merger agreement, the trustees of the Otto Bremer Trust (two of whom currently serve on the Bremer board of directors) entered into a trustee voting agreement with Old National, and each of the directors of Bremer (other than the trustees of the Otto Bremer Trust, who

TABLE OF CONTENTS

have separately entered into the trustee voting agreement) has entered into a director voting agreement with Old National. Pursuant to such voting agreements, subject to their terms, the trustees and directors have agreed to vote their shares of Bremer common stock in favor of approval and adoption of the merger proposal and the adjournment proposal, and to not vote their shares of Bremer common stock in favor of, or otherwise support, any alternative acquisition proposal or any action that is intended to, or could reasonably be expected to, impede, interfere with, delay or otherwise adversely affect the consummation of the transactions contemplated by the merger agreement, as well as certain other restrictions with respect to the voting and transfer of their shares of Bremer common stock. As of the record date, and excluding Bremer common stock beneficially owned by the trustees of the Otto Bremer Trust in their capacities as such, the non-employee directors of Bremer beneficially owned and were entitled to vote 8,101 shares of Bremer common stock, representing less than 1% of the outstanding shares of Bremer common stock entitled to vote on that date. The voting agreements are discussed in more detail in the section entitled “Shareholder Voting Agreements.”

Director Appointment

In connection with the execution of the merger agreement, the trustees of the Otto Bremer Trust (two of whom currently serve as directors of Bremer) entered into the investor agreement with Old National. The investor agreement provides that, among other things, effective as of the effective time of the first step merger, the Old National board of directors will be increased by one director and one of the trustees serving as a trustee of the Otto Bremer Trust immediately prior to the effective time of the first step merger (such person to be determined by the trustees in their sole discretion) will be appointed to the Old National board of directors and will serve in accordance with Old National’s corporate governance guidelines and standards applicable to all directors of Old National.

Executive Officers

Employment Agreement with Jeanne Crain

Bremer is party to a preexisting employment agreement with Jeanne H. Crain, President and Chief Executive Officer of Bremer, which was originally entered into on November 11, 2016 and was amended as of December 20, 2019 and December 15, 2022 (the “Crain Agreement”). Pursuant to the Crain Agreement, if Ms. Crain’s employment is terminated by Bremer without “cause” or by Ms. Crain for “good reason” (each term as defined in the Crain Agreement) within 24 months following the consummation of a change in control of Bremer, she will be entitled to the following payments and benefits: (i) a payment equal to three times the sum of her base salary and target annual bonus for the year of termination; (ii) a pro-rated payment in respect of each of her outstanding long-term incentive performance (“LTIP”) awards for open performance periods, based upon the number of full months elapsed during each award’s three-year performance period and, as per the merger agreement, assuming target level performance is achieved; and (iii) payment of 18 months of COBRA premiums if Ms. Crain is eligible for and elects COBRA coverage. The foregoing payments are conditional on Ms. Crain executing and not revoking a release of claims agreement with Bremer. The Crain Agreement prohibits Ms. Crain from competing with Bremer and soliciting Bremer’s business or employees for a period of two years following her termination of employment.

Based on Ms. Crain’s compensation and outstanding LTIP awards as of January 10, 2025, and assuming a change in control and qualifying termination of employment on January 10, 2025, Ms. Crain would receive approximately $6,783,489 in the aggregate under the Crain Agreement.

Severance and Retention Arrangements with Mitch Bleske

Bremer Bank is party to a preexisting change in control, non-solicitation and severance agreement with Mitch Bleske, Chief Operating Officer and Chief Financial Officer of Bremer, dated as of January 28, 2020 (the “Bleske Agreement”). Pursuant to the Bleske Agreement, if Mr. Bleske’s employment is terminated by Bremer without “cause” or by Mr. Bleske for “good reason” (each term as defined in the Bleske Agreement) within 12 months following a change in control of Bremer, he will be entitled to the following payments and benefits: (i) a payment equal to two times the sum of his base salary and the higher of (a) the highest annual incentive bonus earned by Mr. Bleske during the last three completed fiscal years and (b) Mr. Bleske’s target annual bonus for the year of termination; (ii) a pro-rated portion of his annual bonus for the year of

TABLE OF CONTENTS

termination in an amount at least equal to the applicable pro-rated annual bonus as determined under clause (i) above; (iii) a pro-rated payment in respect of each of his outstanding LTIP awards for open performance periods, based upon the number of full months elapsed during each award’s three-year performance period and, as per the merger agreement, assuming target level performance is achieved; and (iv) up to 12 months of continued health and welfare insurance coverage or, if continued participation in such plans is not permitted, provision of equivalent benefits on the same after-tax basis. The foregoing payments and benefits are conditional on Mr. Bleske executing and not revoking a release of claims agreement with Bremer Bank. The Bleske Agreement prohibits Mr. Bleske from soliciting Bremer’s business or employees for a period of six months following his termination of employment.

Based on Mr. Bleske’s compensation and outstanding LTIP awards as of January 10, 2025, and assuming a change in control and qualifying termination of employment on January 10, 2025, Mr. Bleske would receive approximately $2,686,253 in the aggregate under the Bleske Agreement.

Bremer previously awarded Mr. Bleske a cash retention bonus of $300,000 pursuant to a retention award agreement dated as of August 7, 2024. The retention bonus vested with respect to one half of the award on December 31, 2024, and will vest with respect to the remaining one half of the award on the earlier of June 30, 2025 or the consummation of the mergers, subject to Mr. Bleske’s continued employment on the applicable vesting date.

Pro-rated Annual Bonus

Pursuant to the merger agreement, prior to the consummation of the mergers, Bremer may make pro-rated cash payments in respect of its fiscal year 2025 annual incentive programs based on the greater of target performance and actual performance measured as of the last practicable date prior to the consummation of the mergers. Assuming Bremer elects to make such payments and a change in control occurs on January 10, 2025, based on target performance, the pro-rated cash payment payable to Ms. Crain would be equal to approximately $24,238. Mr. Bleske will not be entitled to receive a pro-rated cash payment pursuant to the merger agreement to the extent such payment would be duplicative of the pro-rated annual bonus for the year of termination under the Bleske Agreement. In light of the foregoing, for purposes of this proxy statement/prospectus, his pro-rated bonus amount is assumed to be calculated under and in accordance with the terms of the Bleske Agreement and is therefore included in the quantification above.

Indemnification Insurance

Under the terms of the merger agreement, from and after the effective time of the mergers, Old National will indemnify, and advance expenses as incurred by, Bremer’s directors and officers, in each case to the extent (subject to applicable law) Bremer’s directors and officers are indemnified or entitled to advancement of expenses by Bremer under the Bremer articles of incorporation and the Bremer bylaws, the governing or organizational documents of any Bremer subsidiary or any contract in existence as of the date of the merger agreement and disclosed to Old National, for costs, expenses, judgments, fines, losses, damages and liabilities arising out of the fact that such person is or was a director or officer Bremer or any of its subsidiaries. In addition, for a period of six years after the effective time of the merger, Old National will maintain in effect the current policies of directors’ and officer’s liability insurance maintained by Bremer or may obtain a six-year “tail” policy under Bremer’s existing directors and officers insurance policy. However, Old National is not obligated to spend for such directors and officers insurance, on an annual basis, or for such “tail” policy, an amount in excess of 300% of the current annual premium paid by Bremer as of the date of the merger agreement. This indemnification and insurance coverage is further described in the section entitled “The Merger Agreement — Director and Officer Indemnification and Insurance.”

Miscellaneous

Bremer has agreed to reimburse the Otto Bremer Trust for certain reasonable legal and financial advisory fees and expenses incurred by Otto Bremer Trust in connection with the mergers, which reimbursement is payable upon closing of the mergers.

TABLE OF CONTENTS

Regulatory Approvals Required for the Mergers

To complete the mergers, Old National and Bremer need to obtain approvals or consents from, or make filings with, applicable U.S. federal bank regulatory authorities and other regulatory authorities. Subject to the terms of the merger agreement, Old National and Bremer have agreed to cooperate with each other and use their reasonable best efforts to as promptly as reasonably practicable to prepare and file all necessary documentation, to effect all applications, notices, petitions and filings, to obtain as promptly as practicable all permits, consents, approvals and authorizations of all third parties and regulatory agencies and governmental entities which are necessary or advisable to consummate the transactions contemplated by the merger agreement (including the mergers and the bank merger), and to comply with the terms and conditions of all such permits, consents, approvals and authorizations of all such regulatory agencies and governmental entities. These include the approvals from the Federal Reserve and the OCC. In furtherance of the foregoing, each of Old National and Bremer agreed to use its reasonable best efforts to resolve any objection that may be asserted by any governmental entity with respect to the merger agreement or the transactions contemplated thereby.

Under the terms of the merger agreement, nothing in the merger agreement will be deemed to require Old National or Bremer to take any action or agree to any condition or restriction that would reasonably be expected to have a material adverse effect on Old National and its subsidiaries, taken as a whole, after giving effect to the mergers.

The regulatory approval of an application means only that the regulatory criteria for approval have been satisfied or waived. It does not mean that the approving authority has determined that the consideration to be received by Bremer shareholders in the mergers is fair. Regulatory approval does not constitute an endorsement or recommendation of the mergers by the applicable regulatory agency.

Old National and Bremer believe that the mergers do not raise regulatory concerns and that they will be able to obtain all requisite regulatory approvals. However, there can be no assurance that all regulatory approvals will be obtained and, if obtained, there can be no assurances regarding the timing of the approvals or the companies’ ability to obtain the approvals on satisfactory terms. In addition, there can be no assurance that such approvals will not impose conditions or requirements that, individually or in the aggregate, would or could reasonably be expected to result in a materially burdensome regulatory condition or to have a material adverse effect on the financial condition, results of operations, assets or business of Old National following the completion of the mergers.

Federal Reserve and the OCC

The mergers are subject to the approval of the Federal Reserve under Section 3 of the BHC Act. The bank merger is subject to the approval of the OCC under section 18(c) of the Federal Deposit Insurance Act (the “Bank Merger Act”) and Section 215a-1 of the National Bank Act (12 U.S.C. § 215a-1). In connection with the bank merger, Old National Bank is also applying for the OCC’s approval to operate Bremer Bank’s main office and branches as licensed branches of Old National Bank under the Bank Merger Act, Sections 36(c) and 36(d) of the National Bank Act (12 U.S.C. §§ 36(c) and 36(d)), and 12 U.S.C. § 1831u(d); and to acquire the subsidiaries of Bremer Bank and operate them as operating subsidiaries of Old National Bank, under 12 U.S.C. § 24, § 24a, all in accordance with 12 C.F.R. part 5.

The Federal Reserve and the OCC take into consideration a number of factors when acting on applications under the BHC Act and the Bank Merger Act and National Bank Act, respectively. These factors include the effect of the mergers on competitiveness in affected banking markets, the financial and managerial resources (including consideration of the capital adequacy, liquidity and earnings performance, as well as the competence, experience and integrity of the directors and officers, and the records of compliance with applicable laws and regulations) and future prospects of the combined company. The Federal Reserve and the OCC also consider the effectiveness of the applicant in combatting money laundering, the convenience and needs of the communities to be served, as well as the extent to which the proposal would result in greater or more concentrated risks to the stability of the U.S. banking or financial system.

In considering an application under the respective provisions of the BHC Act, the Bank Merger Act and the National Bank Act, the Federal Reserve and the OCC also review the records of performance of

TABLE OF CONTENTS

the relevant insured depository institutions under the Community Reinvestment Act (the “CRA”), pursuant to which the Federal Reserve and the OCC must also take into account the record of performance of each of Old National and Bremer in meeting the credit needs of the respective communities, including low- and moderate-income neighborhoods, served by Old National Bank and Bremer Bank. As part of the application review process in merger transactions, the Federal Reserve and the OCC each may receive comment letters from members of the public. In their most recent CRA performance evaluations, Old National Bank received an overall “satisfactory” regulatory rating, and Bremer Bank received an overall “outstanding” regulatory rating, under the CRA.

In addition, in connection with an interstate merger transaction, the Federal Reserve and the OCC consider certain additional factors under the Riegle-Neal Interstate Banking and Branching Efficiency Act of 1994 (12 U.S.C. § 1831u) (the “Riegle-Neal Act”), including the relevant state laws regarding the minimum age of the bank to be acquired, the concentration of deposits on a nationwide and statewide basis, and compliance with any applicable state community reinvestment and antitrust laws. Under the Riegle-Neal Act, the OCC may approve an interstate merger transaction only if each constituent bank is adequately capitalized at the time the application for such transaction is filed with the OCC, and the OCC determines that the resulting bank will be well capitalized and well managed upon the consummation of the transaction.

Furthermore, the Otto Bremer Trust’s acquisition of approximately 11.68% (on a pro forma basis) of the outstanding shares of Old National common stock as a result of its receipt of the merger consideration in the mergers is subject to the prior notice to the Federal Reserve. The Change in Bank Control Act of 1978, as amended (the “CIBC Act”), prohibits a person or group of persons from acquiring control of a bank holding company unless the Federal Reserve has been notified and has not objected to the transaction. Under a rebuttable presumption established by the Federal Reserve, the acquisition of 10% or more of a class of voting stock of a bank holding company with a class of securities registered under Section 12 of the Securities Exchange Act of 1934, as amended (“Exchange Act”), such as Old National, constitutes acquisition of control of the bank holding company. In lieu of the Otto Bremer Trust filing a separate notice under the CIBC Act, information required under the CIBC Act with respect to the Otto Bremer Trust’s acquisition of shares of Old National common stock is provided to the Federal Reserve as part of Old National’s application to the Federal Reserve under Section 3 of the BHC Act. In considering a notice filed under the CIBC Act, the Federal Reserve takes into consideration a number of factors, including whether the acquisition would result in a monopoly, substantially lessen competition, jeopardize the financial stability of the bank or prejudice the interests of the depositors of the bank, or result in an adverse effect on the deposit insurance fund, and whether the competence, experience, or integrity of any acquiring person or of any of the proposed management personnel indicates that it would not be in the interest of the depositors of the bank, or in the interest of the public to permit such person to control the bank.

The initial submission of the applications to the OCC and Federal Reserve occurred on January 20, 2025 and January 21, 2025, respectively. Notice of the applications will also be provided to the North Dakota Department of Financial Institutions.

United States Department of Justice

In addition to the Federal Reserve and the OCC, the Antitrust Division of the U.S. Department of Justice (“DOJ”) conducts a concurrent competitive review of the mergers to analyze the mergers’ competitive effects and determine whether the mergers comply with the antitrust laws. Transactions approved under Section 3 of the BHC Act or the Bank Merger Act generally may not be completed until thirty (30) days after the approval of the applicable federal agency is received, during which time the DOJ may challenge the transaction on antitrust grounds. With the approval of the applicable federal agency and the concurrence of the DOJ, the waiting period may be reduced to no less than fifteen (15) days. The commencement of an antitrust action would stay the effectiveness of such an approval unless a court specifically ordered otherwise. In reviewing the mergers, the DOJ could analyze the mergers’ effect on competition differently than the Federal Reserve and OCC and thus, it is possible that the DOJ could reach a different conclusion than the Federal Reserve or the OCC regarding the mergers’ effects on competition. A determination by the DOJ not to object to the mergers may not prevent the filing of antitrust actions by private persons or state attorneys general.

TABLE OF CONTENTS

Hart-Scott-Rodino Act

The Otto Bremer Trust’s acquisition of shares of Old National common stock as a result of its receipt of the merger consideration in the mergers is subject to the reporting and waiting period requirements of the Hart-Scott-Rodino Antitrust Improvement Act of 1976 (“HSR”). The Otto Bremer Trust and Old National filed HSR Notification and Report Forms with the DOJ and Federal Trade Commission on December 10, 2024, and the HSR waiting period expired on January 9, 2025. The parties have no further obligations under the HSR.

Additional Regulatory Approvals and Notices

Additional notifications and/or applications requesting approval may be submitted to various other federal, state and non-U.S. regulatory authorities and self-regulatory organizations.

Public Trading Markets

Under the merger agreement, Old National will cause the shares of Old National common stock to be issued in the mergers to be approved for listing on the NASDAQ Stock Exchange, subject to official notice of issuance, prior to the effective time of the first step merger. The merger agreement provides that neither Old National nor Bremer will be required to complete the mergers if such shares are not authorized for listing on the NASDAQ Stock Exchange.

Appraisal or Dissenters’ Rights in the Mergers

The following is a summary of certain material terms of Sections 302A.471 and 302A.473 of the MBCA. The summary is not complete and must be read together with the actual statutory provisions, which sections are attached in Annex E to this proxy statement/prospectus. Bremer encourages you to read Sections 302A.471 and 302A.473 of the MBCA carefully and in their respective entirety because the rights and obligations of Bremer and its shareholders are governed by the express terms of these statutory provisions and other applicable law, and not by this summary or any other information contained in this proxy statement/prospectus. This summary may not contain all the information about these statutory provisions that is important to you. All references in this section to “surviving entity” mean Old National, the surviving corporation in the second step merger.

Applicability

As a Minnesota corporation, Bremer is governed by the MBCA. The MBCA provides a shareholder with the right to dissent from the mergers and instead obtain payment for the “fair value” of such shareholder’s shares of Bremer common stock. This right is set forth in Sections 302A.471 and 302A.473 of the MBCA.

This proxy statement/prospectus constitutes Bremer’s notice to its shareholders of the availability of dissenters’ rights in connection with the first step merger in compliance with the requirements of Section 302.473, subdivision 2 of the MBCA.

Exercising Dissenters’ Rights

Any Bremer shareholder contemplating an attempt to assert and exercise dissenters’ rights in connection with the first step merger should review carefully the provisions of Sections 302A.471 and 302A.473 of the MBCA (which sections are attached in Annex E to this proxy statement/prospectus), particularly the specific procedural steps required to perfect such rights. Dissenters’ rights are lost if the procedural requirements of Section 302A.473 of the MBCA are not fully and precisely satisfied. We refer to the shares of Bremer common stock held by a shareholder who has duly and validly demanded appraisal of such shares in connection with the mergers in accordance with Minnesota law and, as of the effective time of the first step

TABLE OF CONTENTS

merger, has not effectively withdrawn or lost such appraisal rights (through failure to perfect or otherwise), as the “dissenting shares.”

In view of the complexity of these statutory provisions, any shareholders who may wish to pursue dissenters’ rights should consult their own legal advisors.

Filing Initial Notice of Dissent before the Special Meeting

Under Section 302A.473, subdivision 3 of the MBCA, a shareholder who wishes to exercise dissenters’ rights (a “dissenting shareholder”), must file with Bremer, before the vote on the merger proposal, a written notice of intent to demand the “fair value” of shares of Bremer common stock owned by such shareholder.

The written notice of intent should be sent to the attention of Amy J. Dorn, Corporate Secretary of Bremer at 380 St. Peter Street, Suite 500, St. Paul, Minnesota 55102 and a copy (which copy will not constitute notice) should also be sent to the attention of Matthew M. Guest and Eric M. Feinstein at Wachtell, Lipton, Rosen & Katz, 51 West 52nd Street, New York, NY 10019, legal counsel to Bremer.

In addition to a dissenting shareholder filing a notice with Bremer before the vote on the merger proposal, the dissenting shareholder must not vote or instruct GreatBanc to vote their shares in favor of the merger proposal. However, a vote or an instruction to GreatBanc to vote against the merger proposal does not in itself constitute a notice of a shareholder’s intent to demand fair value and a failure to vote does not affect the validity of a timely written notice. However, with respect to shares you may hold as a record holder, the submission of a properly signed blank proxy will constitute a vote in favor of the merger proposal and a waiver of statutory dissenters’ rights even if the requisite notice is filed with Bremer.

Under Section 302A.471, subdivision 2 of the MBCA, beneficial owners of shares of Bremer common stock who desire to exercise statutory dissenters’ rights must obtain and submit the registered owner’s written consent at or before the time the notice of intent to demand fair value is due. If you are a beneficial owner of shares of Bremer common stock held through the Bremer 401(k) Plan or the Bremer ESOP and you wish to exercise dissenters’ rights, in addition to complying with the foregoing procedures described in this section entitled “Appraisal or Dissenters’ Rights in the Mergers” and the applicable provisions of the MBCA, you should timely consult with GreatBanc, the independent trustee to the Bremer 401(k) Plan and Bremer ESOP, to determine the appropriate procedures for obtaining such written consent since GreatBanc is the registered owner. If you wish to exercise dissenters’ rights, you cannot instruct GreatBanc to vote your Bremer 401(k) Plan shares and/or Bremer ESOP shares in favor of the merger proposal.

Under Section 302A.471, subdivision 2 of the MBCA, a shareholder may not assert dissenters’ rights as to less than all of the shares of Bremer common stock registered in the name of such shareholder, unless the shareholder dissents with respect to all the shares of Bremer common stock that are beneficially owned by another person but registered in the name of such shareholder and discloses the name and address of each beneficial owner on whose behalf the shareholder dissents. In that event, the rights of the dissenting shareholder will be determined as if the shares of Bremer common stock as to which the shareholder has dissented, and the other shares of Bremer common stock were registered in the names of different shareholders.

Notice of Procedure from Bremer after Shareholder Approval

If the merger proposal is approved by Bremer’s shareholders, Bremer will send to all dissenting shareholders who timely filed the necessary notice of intent to demand the fair value of their shares and who did not vote their shares in favor of the merger proposal a notice (a “notice of procedure”), containing certain information required by Section 302A.473, subdivision 4 of the MBCA, including the address to which a dissenting shareholder must send a demand for payment and certificates representing dissenting shares in order to obtain payment for dissenting shares and the date by which they must be received, any restrictions on transfer of uncertificated dissenting shares that will apply and a form to be used to certify the date on which the dissenting shareholder (or the beneficial owner on whose behalf the dissenting shareholder dissents) acquired such dissenting shares (or an interest in them) and to demand payment.

TABLE OF CONTENTS

Demand for Payment and Deposit of Shares

In order to receive the fair value of the shares under Section 302A.473 of the MBCA, a dissenting shareholder must demand payment and deposit certificates representing certificated shares or comply with any restrictions on transfer of uncertificated shares within 30 days after the notice of procedure is given. Under Section 302A.011, subdivision 17 of the MBCA, such notice is given by Bremer when deposited in the U.S. mail with sufficient postage affixed. A dissenting shareholder who fails to timely make demand for payment and deposit certificates (or comply with any restrictions on transfer of uncertificated shares) as required by Section 302A.473, subdivision 4 of the MBCA, loses the right to receive the fair value of such dissenting shares even if such dissenting shareholder timely filed a notice of intent to demand payment under Section 302A.473, subdivision 3 of the MBCA.

Determination and Payment of “Fair Value”

Except as provided below, if a valid demand for payment and deposit of stock certificates is duly made by a dissenting shareholder, then after Bremer’s or the surviving entity’s receipt of such demand or the effective date of the mergers, whichever is later, the surviving entity must pay the dissenting shareholder an amount which the surviving entity estimates to be the fair value of the dissenting shares, plus interest, if any. The surviving entity will include a brief description of the method used to reach its estimate of fair value. For the purpose of a dissenting shareholder’s rights under Sections 302A.471 and 302A.473 of the MBCA, “fair value” means the value of the shares of stock immediately before the effective date of the mergers. It is possible that the fair value of shares of Bremer common stock as determined pursuant to dissenters’ rights procedures may be determined to be less than the value of the merger consideration. Additionally, “interest” means interest commencing five days after the effective date of such merger until the date of payment, calculated at the rate provided in Minnesota Statutes Section 549.09, subdivision 1, paragraph (c), clause (1), which is currently 4% simple interest per annum.

If a dissenting shareholder believes this payment by the surviving entity is less than the fair value of the dissenting shares, plus interest, if any, such dissenting shareholder must give written notice to the surviving entity of the dissenting shareholder’s own estimate of the fair value of the dissenting shares, plus interest, if any, within 30 days after the date the surviving entity mails the payment, and must demand payment of the difference between the dissenting shareholder’s own estimate and the surviving entity’s payment. If such dissenting shareholder fails to give written notice of such estimate to the surviving entity or fails to demand payment of the difference, within the 30-day time period, such dissenting shareholder is entitled only to the amount of the surviving entity’s payment.

The surviving entity may withhold such payment with respect to dissenting shares for which a dissenting shareholder demanding payment (or persons on whose behalf such dissenting shareholder acts) was not the beneficial owner as of the first public announcement date of the merger agreement, which is November 25, 2024. As to each such dissenting shareholder who has validly demanded payment, following the effective time of the merger or the receipt of demand, whichever is later, the surviving entity must mail its estimate of the fair value of such dissenting shareholder’s dissenting shares and a statement of the reason for withholding the payment, and offer to pay this amount, plus interest, if any, to the dissenting shareholder upon receipt of such dissenting shareholder’s agreement to accept this amount in full satisfaction. The dissenting shareholder may decline the surviving entity’s offer and give written notice to the surviving entity of such dissenting shareholder’s own estimate of the fair value of the dissenting shares, plus interest, if any, and demand payment of this amount. This demand must be mailed to the surviving entity within 30 days after the mailing of the surviving entity’s offer. If the dissenting shareholder fails to make this demand within the 30-day time period, such dissenting shareholder is entitled only to the amount the surviving entity offered.

If the surviving entity receives a demand from a dissenting shareholder (including a dissenting shareholder who held shares of Bremer common stock on November 25, 2024, and a dissenting shareholder who purchased shares of Bremer common stock after that date who has complied with the applicable demand requirements) for a supplemental payment, the surviving entity must, within 60 days after receiving the demand, either pay to the dissenting shareholder the amount demanded or agreed to by the dissenting shareholder after discussion with the surviving entity or file in court a petition requesting that the court determine the statutory fair value of the dissenting shares, plus interest, if any. The petition must be filed in the county in which Bremer’s registered office is located, which is Ramsey County, Minnesota. Bremer’s

TABLE OF CONTENTS

registered office is subject to change at any time. All dissenting shareholders whose demands are not resolved within the applicable 60-day period must be made parties to this proceeding.

The court will then determine whether each dissenting shareholder in question has fully complied with the provisions of Sections 302A.471 and 302A.473 of the MBCA, and for all dissenting shareholders who have fully complied and not forfeited statutory dissenters’ rights, will determine the fair value of the dissenting shares, taking into account any and all factors the court finds relevant (including, without limitation, the recommendation of any appraisers that may have been appointed by the court), computed by any method that the court, in its discretion, sees fit to use, whether or not used by the surviving entity or a dissenting shareholder. The fair value of the dissenting shares as determined by the court is binding on all dissenting shareholders. However, under Minnesota law, dissenting shareholders are not liable to the surviving entity for the amount, if any, by which payments remitted to the dissenting shareholders exceed the fair value of such dissenting shares determined by a court, plus interest, if any. The costs and expenses of such a court proceeding are assessed against the surviving entity, except that the court may assess part or all of those costs and expenses against a dissenting shareholder whose action in demanding payment is found to be arbitrary, vexatious or not in good faith.

Limitation of Other Rights

Under Section 302A.471, subdivision 4 of the MBCA, a shareholder has no right at law or in equity to have the mergers set aside or rescinded, except if the mergers are fraudulent with regard to such shareholder or Bremer.

TABLE OF CONTENTS

THE MERGER AGREEMENT

This section of the proxy statement/prospectus describes the material terms of the merger agreement. The description in this section and elsewhere in this proxy statement/prospectus is subject to, and qualified in its entirety by reference to, the complete text of the merger agreement, which is attached hereto in Annex A. This summary does not purport to be complete and may not contain all of the information about the merger agreement that is important to you. You are urged to read the full text of the merger agreement, as it is the legal document governing the mergers. This section is not intended to provide you with any factual information about Old National or Bremer. Such information can be found elsewhere in this proxy statement/prospectus and in the public filings Old National makes with the SEC, as described in the section entitled “Where You Can Find More Information” beginning on page 103 of this proxy statement/prospectus.

Explanatory Note Regarding the Merger Agreement

The merger agreement and this summary of terms are included to provide you with certain information regarding the terms of the merger agreement. Factual disclosures about Old National and Bremer contained in this proxy statement/prospectus or in documents of Old National filed with the SEC may supplement, update or modify the factual disclosures about Old National and Bremer contained in the merger agreement. The merger agreement contains representations and warranties by Bremer, on the one hand, and by Old National, on the other hand, made solely for the benefit of the other and not for any other party. The representations, warranties and covenants made in the merger agreement by Old National and Bremer were qualified and subject to important limitations agreed to by Old National and Bremer in connection with the negotiation of the terms of the merger agreement. In particular, in your review of the representations and warranties contained in the merger agreement and described in this summary, it is important to bear in mind that the representations and warranties were negotiated with the principal purpose of establishing circumstances in which a party to the merger agreement may have the right not to consummate the mergers if the representations and warranties of the other party prove to be untrue or inaccurate due to a change in circumstance or otherwise, and allocating risk between the parties to the merger agreement, rather than establishing matters as facts. The representations and warranties also may be subject to a contractual standard of materiality different from that generally applicable to shareholders and reports and documents filed with the SEC, and some were qualified by the matters contained in the confidential disclosure schedules that Old National and Bremer each delivered in connection with the merger agreement and certain documents filed by Old National with the SEC. Moreover, information concerning the subject matter of the representations and warranties, which do not purport to be accurate as of the date of this proxy statement/prospectus, may have changed since the date of the merger agreement. Accordingly, the representations and warranties in the merger agreement should not be relied on by any persons as characterizations of the actual state of facts about Old National and Bremer at the time they were made or otherwise. For more information, see “Where You Can Find More Information” beginning on page 103.

Structure of the Mergers

Each of Bremer’s and Old National’s respective boards of directors have unanimously approved and adopted the merger agreement. Under the merger agreement, ONB Merger Sub will first merge with and into Bremer, with Bremer as the surviving corporation in the first step merger as a wholly-owned subsidiary of Old National. Immediately following the first step merger, and as part of a single, integrated transaction, Bremer will then merge with and into Old National, with Old National as the surviving corporation in the second step merger. Immediately following the second step merger, or at a later time as determined by Old National, Bremer’s wholly-owned banking subsidiary, Bremer Bank will merge with and into Old National’s wholly-owned banking subsidiary, Old National Bank, with Old National Bank as the surviving bank.

Prior to the consummation of the mergers, Old National and Bremer may, by mutual agreement, change the method or structure of effecting the combination of Old National and Bremer if and to the extent they both deem such change to be necessary, appropriate or desirable; provided, however that no such change may (i) alter or change the merger consideration; (ii) adversely affect the tax treatment of Bremer’s shareholders or Old National’s shareholders relating to the mergers; (iii) adversely affect the tax treatment of Bremer or Old National pursuant to the merger agreement; or (iv) materially impede or delay the consummation of the mergers in a timely manner.

TABLE OF CONTENTS

Merger Consideration

Pursuant to the terms and subject to the conditions set forth in the merger agreement, Bremer shareholders will receive cash and Old National common stock for each of their shares of Bremer common stock. At the effective time of the first step merger, each outstanding share of Bremer common stock (except for dissenting shares, shares of treasury stock or shares owned by Bremer, Old National or ONB Merger Sub, in each case other than shares held in trust accounts, managed accounts, mutual funds and the like, or otherwise held in a fiduciary or agency capacity that are beneficially owned by third parties, or held, directly or indirectly, as a result of debts previously contracted) will be converted into the right to receive (i) $26.22 in cash without interest and (ii) 4.182 shares of Old National common stock. No fractional shares of Old National common stock will be issued in the mergers and holders of Bremer common stock will be entitled to receive cash in lieu of fractional shares. Because the merger consideration is comprised of a fixed amount of cash consideration plus a fixed amount of shares of Old National common stock for each share of Bremer common stock, the market value of the merger consideration will fluctuate with the market price of Old National common stock and will not be known at the time Bremer shareholders vote on the merger agreement. Based on the closing stock price of Old National common stock on the NASDAQ Stock Exchange, as reported by The Wall Street Journal, of $23.58 as of January 28, 2025, the value of the per share merger consideration payable to holders of Bremer common stock was approximately $124.83 as of such date.

Fractional Shares

Old National will not issue any fractional shares of Old National common stock in the mergers. Instead, a former holder of Bremer common stock who otherwise would have received a fraction of a share of Old National common stock will receive an amount in cash rounded to the nearest cent. This cash amount will be determined by multiplying (i) the average of the closing-sale prices of Old National common stock on the NASDAQ Stock Exchange as reported by The Wall Street Journal for the five (5) full trading days ending on the trading day immediately preceding the closing date of the mergers by (ii) the fraction of a share (rounded to the nearest one-thousandth when expressed in decimal form) of Old National common stock which such holder would otherwise be entitled to receive.

Governing Documents

At the effective time of the second step merger, the Old National articles of incorporation and the Old National bylaws as in effect immediately prior to the effective time shall be the articles of incorporation and bylaws of the combined company until thereafter amended in accordance with applicable law.

Closing and Effective Time of the Mergers

The closing will occur by electronic exchange of documents at 8:00 a.m., Minneapolis time, on the first business day of the month immediately following the month during which the satisfaction or waiver (subject to applicable law) of the latest to occur of the conditions set forth in the merger agreement (other than those conditions that by their nature can only be satisfied at the closing of the first step merger, but subject to the satisfaction or waiver thereof), or, if such business day is not at least five (5) business days after the aforementioned satisfaction or waiver, then the first business day of the second month after satisfaction or waiver (subject to applicable law) of the latest to occur of the conditions set forth in the merger agreement (other than those conditions that by their nature can only be satisfied at the closing of the first step merger, but subject to the satisfaction or waiver thereof), unless another date, time or place is agreed to in writing by Old National and Bremer.

On the closing date, Old National and Bremer will cause to be filed the articles of merger with respect to the first step merger with the Secretary of State of the State of Minnesota and the Secretary of State of the State of Indiana. The first step merger will become effective at such time as set forth in the articles of merger in accordance with the MBCA and the Indiana Business Corporation Law (the “IBCL”) (the “effective time”).

Immediately following the effective time of the first step merger, in accordance with the MBCA and IBCL, Old National will cause the surviving corporation to be merged with and into Old National in the

TABLE OF CONTENTS

second step merger, with Old National surviving the second step merger as the combined company and continuing its existence under the laws of Indiana, and the separate corporate existence of the surviving corporation will cease as of the second effective time. In furtherance of the foregoing, Old National will cause to be filed with the Secretary of State of the State of Minnesota, in accordance with the MBCA, and the Secretary of State of the State of Indiana, in accordance with the IBCL, articles of merger relating to the second step merger. The second step merger will become effective at such time as specified in the relevant articles of merger in accordance with the relevant provisions of the MBCA and IBCL, or at such other time as provided by applicable law (the “second effective time”).

Exchange of Shares

Old National to Make Consideration Available

At or prior to the effective time of the first step merger, Old National shall deposit with the exchange agent, for the benefit of Bremer shareholders, (i) certificates or evidence of shares in book entry form representing shares of Old National common stock to be issued to holders of Bremer common stock, and (ii) an amount in cash by wire transfer equal to the aggregate cash merger consideration and aggregate cash in lieu of fractional shares to be paid to holders of Bremer common stock in exchange for shares of Bremer common stock.

Exchange Procedures

As promptly as practicable after the effective time of the mergers, but in no event later than five (5) business days thereafter, Old National will cause the exchange agent to mail to each holder of record of one (1) or more certificates (which, for purposes of this proxy statement/prospectus, shall be deemed to include certificates or book-entry account statements) representing shares of Bremer common stock immediately prior to the effective time, a letter of transmittal and instructions for use in effecting the surrender of such old certificate(s) in exchange for the merger consideration, including new certificates (which, for purposes of this proxy statement/prospectus, shall be deemed to include certificates or evidence in book-entry form) representing the number of whole shares of Old National common stock which shares of Bremer common stock represented by such old certificate(s) shall have been converted into the right to receive pursuant to the merger agreement, as well as any cash in lieu of fractional shares and dividends or distributions to be paid pursuant to the merger agreement as described in “— Dividends and Distributions” below.

If a certificate for Bremer common stock has been lost, stolen or destroyed, the exchange agent will issue the consideration in the mergers upon receipt of (i) an affidavit of that fact by the claimant and (ii) if required by Old National, the posting of a bond by such claimant in an amount as Old National may determine is reasonably necessary as indemnity against any claim that may be made against it with respect to such old certificate.

After the effective time of the mergers, there will be no further transfers on the stock transfer books of Bremer of Bremer common stock that were issued and outstanding immediately prior to the effective time.

Withholding

Each of Old National and the exchange agent will be entitled to deduct and withhold from any consideration otherwise payable pursuant to the merger agreement to any holder of Bremer common stock the amounts it is required to deduct and withhold under the Code or any provision of state, local, or foreign tax law. Old National or the exchange agent, as applicable, will make commercially reasonable efforts to provide notice to the applicable payee of its intent to deduct or withhold and the basis for such deduction or withholding before any such deduction or withholding is made, and reasonably cooperate with such payee in order to eliminate or to reduce any such deduction or withholding, including providing a reasonable opportunity for such payee to provide forms or other evidence that would mitigate, reduce or eliminate such deduction or withholding. If any such amounts are withheld and paid over to the appropriate governmental authority, such amounts will be treated for all purposes of the merger agreement as having been paid to the holder from whom they were withheld and deducted.

TABLE OF CONTENTS

Dividends and Distributions

Following the effective time of the mergers, no dividends or other distributions declared with respect to Old National common stock will be paid to the holder of any unsurrendered certificate representing shares of Bremer common stock until the holder surrenders such old certificate in accordance with the merger agreement. After the surrender of an old certificate in accordance with the merger agreement, the record holder thereof will be entitled to receive any such dividends or other distributions, without any interest, which had previously become payable with respect to the whole shares of Old National common stock which the shares of Bremer common stock represented by such old certificate have been converted into the right to receive under the merger agreement.

Each of Old National and Bremer has agreed to use its reasonable best efforts to resolve any objection that may be asserted by any governmental entity with respect to the merger agreement or the transactions contemplated thereby. However, in no event will Bremer or Old National, or any of their respective subsidiaries be required, and neither Bremer or Old National, nor any of their respective subsidiaries be permitted (without the written consent of the other party), to take any action, or commit to take any action, or agree to any condition or restriction, in connection with obtaining the required permits, consents, approvals and authorizations of governmental entities that would reasonably be expected to result in a materially burdensome regulatory condition.

Old National and Bremer have also agreed to furnish each other with all information concerning themselves, their subsidiaries, directors, officers and shareholders and such other matters as may be reasonably necessary or advisable in connection with this proxy statement/prospectus and any statement, filing, notice or application to any governmental entity in connection with the mergers and the other transactions contemplated by the merger agreement, as well as to keep each other apprised of the status of matters related to the consummation of the transactions contemplated by the merger agreement.

Employee Matters

The merger agreement provides that, Old National will provide to Bremer continuing employees for as long as they are employed during the period commencing on the effective time and for one year following the effective time, (i) base salary or base wage rate, as applicable, that is no less favorable than the base salary or base wage rate, as applicable, provided by Bremer or its subsidiaries to such continuing employee immediately prior to the effective time, (ii) short-term, annual and long-term incentive compensation target opportunities that are no less favorable, in the aggregate, than the short-term, annual and long-term incentive compensation target opportunities provided by Bremer or its subsidiaries to such continuing

TABLE OF CONTENTS

employee immediately prior to the effective time and (iii) other compensation and employee benefits that are no less favorable, in the aggregate, to the other compensation and employee benefits (excluding defined benefit pension plans benefits and ESOP benefits) provided by Bremer or its subsidiaries to such continuing employee immediately prior to the effective time. Old National has also agreed that it, or one of its subsidiaries, will provide to each continuing employees of Bremer whose employment terminates during the one-year period following the closing of the mergers with the severance benefits that are provided under and pursuant to the Old National’s severance plan; provided that such severance benefits will be determined (A) without taking into account any reduction after the closing of the mergers in compensation paid to such continuing employee and (B) taking into account each continuing employee’s service with Bremer and its subsidiaries (and any predecessor entities) prior to the closing of the mergers (based on the continuing employee’s original hire date as reflected in Bremer’s records), and, on or after the closing of the mergers, Old National and its subsidiaries.

The merger agreement also provides that, with respect to any employee benefit plans of Old National or its subsidiaries in which any continuing employees become eligible to participate on or after the effective time (the “new plans”), Old National will, (i) waive all pre-existing conditions, exclusions and waiting periods with respect to participation and coverage requirements applicable to such continuing employees and their eligible dependents under any new plans, except to the extent such waiting periods would apply under the analogous Bremer benefit plan, (ii) use commercially reasonable efforts to provide each such employee and their eligible dependents with credit for any eligible expenses incurred by such employee or dependent prior to the effective time under a Bremer benefit plan, to the same extent that such credit was given under the analogous Bremer benefit plan prior to the effective time, in satisfying any applicable deductible, co-payment or out-of-pocket requirements under any new plan, and (iii) recognize all service of such employees with Bremer and its subsidiaries for all purposes in any new plan to the same extent such service was taken into account under the analogous Bremer benefit plan prior to the effective time. The foregoing service recognition do not apply to the extent it would result in duplication of benefits for the same period of services.

Old National shall, or shall cause one of its subsidiaries to, assume and honor all Bremer benefit plans in accordance with their terms. Old National acknowledged in the merger agreement that a “change in control” (or similar phrase) within the meaning of the Bremer benefit plans will occur at the effective time of the mergers.

Bremer shall cause any 401(k) plan sponsored or maintained by Bremer or any of its subsidiaries to be terminated effective as of the day immediately prior to the effective time and contingent upon the occurrence of the closing of the mergers. The continuing employees will be eligible to participate, effective as soon as administratively practicable following the effective time of the mergers (but no later than the second payroll period following the closing), in a 401(k) plan sponsored or maintained by Old National or one of its subsidiaries. Old National and Bremer will take any and all actions as may be required to permit the continuing employees who are then actively employed to make rollover contributions to the Old National 401(k) Plan of “eligible rollover distributions” (within the meaning of Section 401(a)(31) of the Code) in the form of cash, Old National common stock or notes (in the case of loans), or a combination thereof. Prior to the effective time, Bremer or its subsidiaries may make an employer contribution (at a level determined in the ordinary course of business consistent with past practice) to any Bremer 401(k) plan for the year in which the effective time occurs or any prior year.

Bremer shall cause its employee stock ownership plan to be terminated effective as of the day immediately prior to the effective time and contingent upon the occurrence of the closing of the mergers. Bremer and Old National shall take any and all actions as may be required to permit the continuing employees to make rollover contributions of “eligible rollover distributions” (within the meaning of Section 401(a)(31) of the Code) to the Old National 401(k) Plan of distributions in the form of cash, Old National Common Stock or a combination thereof.

Nothing in the merger agreement will confer upon any employee, director or consultant of Bremer or any of its subsidiaries or affiliates any right to continue in the employ or service of Bremer, Old National or any subsidiary or affiliate thereof, or will interfere with or restrict in any way the rights of Bremer, Old National or any subsidiary or affiliate thereof to discharge or terminate the services of any employee, director or consultant of Bremer or any of its subsidiaries or affiliates at any time for any reason whatsoever, with

Nothing in the merger agreement will be deemed to (i) establish, amend, or modify any Bremer benefit plan, new plan or any other benefit or employment plan, program, agreement or arrangement, or (ii) alter or limit the ability of Old National or any of its subsidiaries or affiliates to amend, modify or terminate any particular Bremer benefit plan, new plan or any other benefit or employment plan, program, agreement or arrangement after the effective time. Nothing in the merger agreement, express or implied, is intended to or will confer upon any person, including any current or former employee, director or consultant of Bremer or any of its subsidiaries or affiliates, any right, benefit or remedy of any nature whatsoever under or by reason of the merger agreement.

The merger agreement provides that from and after the effective time of the mergers, Old National will indemnify and hold harmless and will advance expenses as incurred, in each case to the extent (subject to applicable law) such persons were indemnified or entitled to advancement of expenses as of the date of the merger agreement by Bremer pursuant to the Bremer articles of incorporation, the Bremer bylaws, the governing or organizational documents of any subsidiary of Bremer or any contract in existence as of the date of the merger agreement and disclosed to Old National, each present and former director and officer of Bremer and its subsidiaries (in each case, when acting in such capacity) against any costs or expenses (including reasonable attorneys’ fees), judgments, fines, losses, damages or liabilities incurred in connection with any threatened or actual claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative, whether arising before or after the effective time of the mergers, arising out of the fact that such person is or was a director or officer of Bremer or any of its subsidiaries and pertaining to matters, acts or omissions existing or occurring at or prior to the effective time of the mergers, including matters, acts or omissions occurring in connection with the approval of the merger agreement and the transactions contemplated by the merger agreement. In the case of advancement of expenses, the Bremer indemnified party to whom expenses are advanced must provide an undertaking to repay such advances if it is ultimately determined that such Bremer indemnified party is not entitled to indemnification.

The merger agreement requires Old National, as the surviving entity in the mergers, to maintain for a period of six years after the effective time, Bremer’s existing directors’ and officers’ liability insurance policy, or policies with a substantially comparable insurer of at least the same coverage and amounts and containing terms and conditions that are no less advantageous to the insured, with respect to claims against the present and former officers and directors of Bremer or any of its subsidiaries arising from facts or events that occurred at or prior to the consummation of the mergers. However, Old National is not required to spend annually more than 300% of the current annual premium paid as of the date of the merger agreement by Bremer for such insurance (the “premium cap”), and if such premiums for such insurance would at any time exceed that amount, then Old National will maintain policies of insurance which provide the maximum coverage available at an annual premium equal to the premium cap. In lieu of the foregoing, Bremer, in consultation with Old National, may obtain at or prior to the effective time a six-year “tail” policy under Bremer’s existing directors and officers insurance policy providing equivalent coverage to that described in the preceding sentence if such a policy can be obtained for an amount that, in the aggregate, does not exceed the premium cap.

Certain Additional Covenants

The merger agreement also contains additional covenants, including, among others, covenants relating to the filing of this proxy statement/prospectus and regulatory applications, obtaining required Bremer shareholder approval, the listing of the shares of Old National common stock be issued in the mergers, access to information of the other company, advice of changes, exemption from takeover restrictions, shareholder litigation relating to the transactions contemplated by the merger agreement, the coordination of dividend declarations, the assumption by Old National of Bremer’s indebtedness, certain governance matters and public announcements with respect to the transactions contemplated by the merger agreement.

Agreement Not to Solicit Other Offers

Bremer has agreed that it will, and will cause its officers, directors, employees, agents, advisors and representatives (collectively, “representatives”), to, immediately cease and cause to be terminated, any

TABLE OF CONTENTS

activities, discussions or negotiations conducted before the date of the merger agreement with any person other than Old National with respect to any acquisition proposal.

Bremer has agreed that it will not, and will cause its subsidiaries and its and their respective representatives not to, directly or indirectly, (i) initiate, solicit, knowingly encourage or knowingly facilitate any inquiries or proposals with respect to any acquisition proposal, (ii) engage or participate in any negotiations concerning any acquisition proposal, (iii) provide any confidential or nonpublic information or data to, or have or participate in any discussions with, any person relating to any acquisition proposal or (iv) unless the merger agreement has been terminated in accordance with its terms, approve or enter into any term sheet, letter of intent, indication of interest, commitment, memorandum of understanding, agreement in principle, acquisition agreement, merger agreement or other agreement (other than a confidentiality agreement referred to and entered into in accordance with the merger agreement) in connection with or relating to any acquisition proposal, except in each case to notify a person that has made or, to the knowledge of Bremer, is making any inquiries with respect to, or is considering making, an acquisition proposal, of the existence of these provisions of the merger agreement. However, prior to the approval of the merger agreement by the Bremer shareholders, if Bremer receives an unsolicited bona fide written acquisition proposal that did result from or arise in connection with a breach of the restrictions on acquisition proposals set forth above, Bremer may, and may permit its subsidiaries and its and its subsidiaries’ representatives to, furnish or cause to be furnished confidential or nonpublic information or data and participate in such negotiations or discussions if the Bremer board of directors concludes in good faith (after receiving the advice of its outside counsel, and with respect to financial matters, its financial advisors) that failure to take such actions would be more likely than not to result in a violation of its fiduciary duties under applicable law; provided, further, that, prior to providing any confidential or nonpublic information, Bremer enters into a confidentiality agreement with such third party making such acquisition proposals on terms no less favorable to it than the confidentiality agreement between Bremer and Old National, and which confidentiality agreement must not provide such person with any exclusive right to negotiate with Bremer.

For purposes of the merger agreement, an “acquisition proposal” means other than the transactions contemplated by the merger agreement, any offer, proposal or inquiry relating to, or any third party indication of interest in, (i) any acquisition or purchase, direct or indirect, of 25% or more of the consolidated assets of Bremer and its subsidiaries or 25% or more of any class of equity or voting or nonvoting securities of Bremer or its subsidiaries whose assets, individually or in the aggregate, constitute 25% or more of the consolidated assets of Bremer, (ii) any tender offer (including a self-tender offer) or exchange offer that, if consummated, would result in such third party beneficially owning 25% or more of any class of equity or voting or nonvoting securities of Bremer or its subsidiaries whose assets, individually or in the aggregate, constitute 25% or more of the consolidated assets of Bremer, or (iii) a merger, consolidation, share exchange, business combination, reorganization, recapitalization, liquidation, dissolution or other similar transaction involving Bremer or its subsidiaries whose assets, individually or in the aggregate, constitute 25% or more of the consolidated assets of Bremer.

Bremer has agreed to promptly (within 24 hours) advise Old National following receipt of any acquisition proposal or any inquiry which could reasonably be expected to lead to an acquisition proposal (including the terms and conditions of, and the identity of the person making, such inquiry or acquisition proposal), provide Old National with an unredacted copy of any such acquisition proposal and any draft agreements, proposals or other materials received in connection with any such inquiry or acquisition proposal and keep Old National apprised of any related developments, discussions and negotiations on a current basis, including any amendments to or revisions of the terms of such inquiry or acquisition proposal.

•

the accuracy of the representations and warranties of the other party contained in the merger agreement as of the date on which the merger agreement was entered into and as of the date on which the mergers are completed, subject to the materiality standards provided in the merger agreement (and the receipt by each party of an officers’ certificate from the other party to such effect);

•

the performance by the other party in all material respects of all obligations and covenants required to be performed by it under the merger agreement at or prior to the date on which the mergers are completed (and the receipt by each party of an officers’ certificate from the other party to such effect);

•

receipt by each party of an opinion of legal counsel to the effect that on the basis of facts, representations and assumptions set forth or referred to in such opinion, the mergers, taken together, will qualify as a “reorganization” within the meaning of Section 368(a) of the Code; and

•

solely with respect to Old National’s obligation to close, Bremer’s adjusted tangible shareholder’s equity as of the month-end at least five business days before the date on which the last of the other closing conditions is satisfied being equal to or exceeding $1.3 billion.

Neither Bremer nor Old National can provide assurance as to when or if all of the conditions to the mergers can or will be satisfied or waived by the appropriate party.

Termination of the Merger Agreement

The merger agreement can be terminated at any time prior to the consummation of the mergers, whether before or after the receipt of the requisite Bremer vote of its shareholders at the special meeting of shareholders, in the following circumstances:

•

by mutual written consent of Old National and Bremer;

•

by either Old National or Bremer if any governmental entity that must grant a requisite regulatory approval has denied approval of the mergers or the bank merger and such denial has become final and nonappealable or any governmental entity of competent jurisdiction has issued a final and nonappealable order, injunction, decree or other legal restraint or prohibition permanently enjoining or otherwise prohibiting or making illegal the mergers or the bank merger, unless the failure to obtain a requisite regulatory approval is due to the failure of the party seeking to terminate the merger agreement to perform or observe its covenants and agreements under the merger agreement;

•

by either Old National or Bremer if the mergers have not been completed on or before November 25, 2025, unless the failure of the mergers to be completed by such date is due to the failure of the party seeking to terminate the merger agreement to perform or observe its covenants and agreements under the merger agreement; provided that, if on such date, the closing conditions relating to the requisite regulatory approvals shall not have been satisfied or waived, but all other conditions to closing have been satisfied or waived, such termination date shall be automatically extended to February 25, 2026; provided further, that if all closing conditions in the merger agreement are satisfied on a date that occurs prior to the initial termination date but under the terms of the merger agreement the closing would occur after the termination date, the termination date shall be extended to the specified date;

TABLE OF CONTENTS

•

by either Old National or Bremer (provided that the terminating party is not then in material breach of any representation, warranty, obligation, covenant or other agreement contained in the merger agreement) if there is a breach of any of the obligations, covenants or agreements or any of the representations or warranties (or any such representation or warranty ceases to be true) set forth in the merger agreement on the part of Bremer, in the case of a termination by Old National, or Old National or ONB Merger Sub, in the case of a termination by Bremer, which either individually or in the aggregate would constitute, if occurring or continuing on the date the mergers are completed, the failure of a closing condition of the terminating party and which is not cured within forty-five (45) days following written notice to the party committing such breach, or by its nature or timing cannot be cured during such period (or such fewer days as remain prior to the termination date); or

•

by Old National prior to such time as the requisite Bremer vote is obtained, if (i) the Bremer board of directors shall have (a) failed to recommend in this proxy statement/prospectus that the shareholders of Bremer approve the merger agreement, or withheld, withdrawn, modified or qualified such recommendation in a manner adverse to Old National, (b) adopted, approved, recommended or endorsed an alternative acquisition proposal or publicly disclosed its intention to do so, or failed to publicly and without qualification recommend against such alternative acquisition proposal or reaffirm the its recommendation that the shareholders of Bremer approve the merger agreement, within ten (10) business days after an alternative acquisition proposal is made public or any request by Old National to do so or (c) publicly proposed to do any of the foregoing or (ii) Bremer or the Bremer board of directors has breached in any material respect its obligations relating to shareholder approval or the non-solicitation of acquisition proposals.

Neither Old National nor Bremer is permitted to terminate the merger agreement as a result of any increase or decrease in the market price of Old National common stock or Bremer common stock.

Effect of Termination

If the merger agreement is terminated, it will become void and have no effect, except that (i) none of Bremer, Old National or ONB Merger Sub will be relieved or released from any liabilities or damages arising out of its fraud or willful and material breach of any provision of the merger agreement and (ii) designated provisions of the merger agreement will survive the termination, including those relating to payment of fees and expenses, the confidential treatment of information and the termination fee described below.

Termination Fee

Bremer will pay Old National a termination fee equal to $55,000,000 in cash (the “termination fee”), if the merger agreement is terminated in the following circumstances:

•

in the event that after the date of the merger agreement, a bona fide acquisition proposal has been made known to senior management or the Bremer board of directors, or has been made directly to Bremer’s shareholders generally, or any person has publicly announced (and in each case, not withdrawn at least two business days prior to the Bremer special meeting) an acquisition proposal with respect to Bremer, and thereafter (i) the merger agreement is terminated (a) by either Old National or Bremer because the first step merger has not been completed prior to the termination date (and Bremer has not obtained shareholder approval of the merger proposal) and all other conditions for Bremer to close the mergers had been satisfied or were capable of being satisfied at a time prior to such termination or (b) by Old National as a result of a willful breach of a representation, warranty, covenant or other agreement in the merger agreement by Bremer that would constitute the failure of a closing condition and that has not been cured during the permitted time period, or by its nature cannot be cured during such period, and (ii) prior to the date that is 12 months after the date of such termination, Bremer enters into a definitive agreement with respect to an acquisition proposal or consummates a transaction with respect to an acquisition proposal (in each case, with references to “25%” in the definition of “acquisition proposal” instead referring to “50%”); or

•

if the merger agreement is terminated by Old National because prior to receipt of Bremer shareholders’ approval of the merger proposal, (i) the Bremer board of directors has made a

TABLE OF CONTENTS

recommendation change or (ii) Bremer or the Bremer board of directors has breached its obligations relating to shareholder approval or the non-solicitation of acquisition proposals in any material respect.

Except in the case of actual and intentional fraud or willful and material breach, the maximum aggregate amount of fees, liabilities or damages payable by Bremer under the merger agreement will be equal to the termination fee (together with any costs, fees and interest as specified in the merger agreement), as applicable, and in no event shall Bremer be required to pay the termination fee on more than one occasion.

Expenses and Fees

Except as otherwise provided in the merger agreement, all costs and expenses incurred in connection with the merger agreement and the transactions contemplated thereby will be paid by the party incurring such expense. The merger agreement provides that all filing and other fees paid to the SEC or any other governmental entity in connection with the mergers, the bank merger and the other transactions contemplated by the merger agreement will be borne equally by Old National and Bremer.

Amendment, Waiver and Extension of the Merger Agreement

Subject to compliance with applicable law, the merger agreement may be amended by the parties, by action taken or authorized by their respective boards of directors, at any time before or after the receipt of the requisite vote of the Bremer shareholders, except that after the receipt of the requisite vote of the Bremer shareholders, there may not be, without further approval of the Bremer shareholders, any amendment to the merger agreement that requires such further approval of such shareholders under applicable law.

At any time prior to the effective time of the mergers, each of the parties may, to the extent legally allowed, (i) extend the time for the performance of any of the obligations or other acts of the other party, (ii) waive any inaccuracies in the representations and warranties of the other party contained in the merger agreement or in any document delivered by such other parties pursuant to the merger agreement, and (iii) waive compliance with any of the agreements or satisfaction of any conditions contained in the merger agreement, except that after the receipt of the requisite Bremer vote, there may not be, without further approval of the Bremer shareholders, any extension or waiver of the merger agreement or any portion thereof that requires such further approval of such shareholders under applicable law.

Governing Law

The merger agreement is governed by and will be construed in accordance with the laws of the State of Indiana, without regard to any applicable conflicts of law, except the first step and second step Minnesota articles of merger will be governed by the laws of the State of Minnesota and the first step and second step Indiana articles of merger will be governed by the laws of the State of Indiana, and matters relating to the fiduciary duties of the Bremer board of directors and the trustees of the Otto Bremer Trust will be subject to the laws of the State of Minnesota.

Specific Performance

Old National, Bremer and ONB Merger Sub will be entitled to specific performance of the terms of the merger agreement, including an injunction or injunctions to prevent breaches or threatened breaches of the merger agreement or to enforce specifically the performance of the terms and provisions of the merger agreement (including the parties’ obligations to consummate the mergers), in addition to any other remedy to which they are entitled at law or in equity.

SHAREHOLDER VOTING AGREEMENTS

The following describes certain material provisions of the trustee voting agreement and the director voting agreements. This description of the trustee voting agreement and the director voting agreement is subject to, and qualified in its entirety by reference to, the trustee voting agreement, which is attached to this proxy statement/prospectus as Annex B, and the form of director voting agreement, which is attached to this proxy statement/prospectus as Annex C. You are urged to read the trustee voting agreement and form of director voting agreement (together, the “shareholder voting agreements”) carefully and in their entirety.

Concurrently with the execution of the merger agreement, on November 25, 2024, Old National entered into a voting agreement with the trustees on behalf of the Otto Bremer Trust and a voting agreement with each of the directors of Bremer (other than the trustees that are directors of Bremer), who are also Bremer shareholders, in their respective capacities as Bremer shareholders and not in their capacities as an officer or director of Bremer, as the case may be. As of the record date for the Bremer annual meeting, these directors and the Otto Bremer Trust collectively and beneficially owned 86.20% of the outstanding shares of Bremer common stock.

Voting

Under the shareholder voting agreements, each such shareholder (and in the case of the trustee voting agreement, the trustees) agrees to, among other things, at any meeting or action of shareholders of Bremer called to vote upon the merger proposal (i) appear at such or meeting or otherwise cause such shareholder’s shares of Bremer common stock to be counted as present thereat for the purpose of establishing a quorum, (ii) vote such shareholder’s shares of Bremer common stock (or otherwise provide a proxy, consent or voting instruction or direction) in favor of (a) approval of the merger proposal and (b) the adjournment proposal, (iii) not initiate any proxy solicitation or undertake any other efforts against the merger agreement, the mergers or the transactions contemplated by the merger agreement, and (iv) not vote such shareholder’s shares of Bremer common stock (or otherwise provide a proxy or consent) in favor of, or otherwise support, an alternative acquisition proposal with respect to Bremer or any action that is intended to, or could reasonably be expected to impede, interfere with, delay or otherwise adversely affect the mergers or the transactions contemplated by the merger agreement.

Restrictions on Transfer

Each such shareholder (and in the case of the trustee voting agreement, the trustees) also agrees not to, directly or indirectly, sell, offer for sale, transfer, pledge, assign, encumber or otherwise dispose of, or enter into any contract, agreement, option, commitment, derivative or other arrangement or understanding with respect to any sale, offer for sale, transfer, pledge, assignment, encumbrance or other disposition of any of such shareholder’s shares or the voting rights thereunder from the date of the merger agreement until the effective time of the mergers without the prior written consent of Old National.

Other Covenants

Under the shareholder voting agreements, each such shareholder (and in the case of the trustee voting agreement, the trustees) also agrees not to, and agrees to direct and use their respective reasonable best efforts to cause their agents and representatives not to, directly or indirectly, (i) initiate, solicit, knowingly encourage or knowingly facilitate inquiries or proposals with respect to any acquisition proposal with respect to Bremer, (ii) engage or participate in any negotiations with any person concerning any acquisition proposal with respect to Bremer, (iii) provide any confidential or nonpublic information or data to, or have or participate in any discussions with, any person relating to an acquisition proposal with respect to Bremer, (iv) enter into any term sheet, letter of intent, indication of interest, commitment, memorandum of understanding, agreement in principle, acquisition agreement, merger agreement or other agreement in connection with or relating to any acquisition proposal with respect to Bremer, or (v) solicit proxies or initiate a shareholder vote with respect to an acquisition proposal with respect to Bremer or otherwise knowingly facilitate any effort or attempt to make or implement an acquisition proposal with respect to Bremer, except in each case to notify a person that has made or, to the knowledge of such shareholder, is making any inquiries with respect to, or is considering making, an acquisition proposal with respect to Bremer, of the existence of these provisions. However, in the event Bremer is engaging in discussions or negotiations with a person making an acquisition

TABLE OF CONTENTS

proposal in accordance with the merger agreement with respect to such acquisition proposal, each such shareholder (and in the case of the trustee voting agreement, the trustees) and such shareholder’s (or such trustees’) agents and representatives will be entitled to engage in any discussions or negotiations that Bremer is permitted to engage in pursuant to the merger agreement with respect to such acquisition proposal.

Each such shareholder also agrees to waive and not to exercise or perfect any rights of appraisal or rights to dissent from the first step merger that such shareholders may have with respect to such shareholder’s shares of Bremer common stock under applicable law, to the extent permitted by applicable law.

Termination

Each shareholder voting agreement will terminate upon the earliest to occur of (i) the termination of the merger agreement in accordance with its terms, (ii) the Bremer board of directors making a recommendation change in accordance with the terms of the merger agreement, (iii) the entry into any amendment, modification, waiver or other change to any provision of the merger agreement without the shareholder’s (and, in the case of the trustee voting agreement, the trustees’) prior written consent that (a) diminishes the amount or changes the form of the merger consideration, (b) extends the termination date or imposes any additional conditions or obligations that would reasonably be expected to materially impede or delay the consummation of the transactions contemplated by the merger agreement, or (c) otherwise would reasonably expected to adversely affect the rights or obligations of the shareholder (and in the case of the trustee voting agreement, the trustees) in connection with the transactions contemplated by the merger agreement and (iv) the effective time of the mergers.

TABLE OF CONTENTS

ACCOUNTING TREATMENT

The mergers will be accounted for as an acquisition of Bremer by Old National under the acquisition method of accounting in accordance with U.S. GAAP for financial reporting and accounting purposes. After the mergers, the results of operations of Bremer will be included in the consolidated financial statements of Old National. The merger consideration will be allocated based on the fair values of the assets acquired and the liabilities assumed. Any excess of merger consideration over fair value of the net tangible and identified intangible assets of Old National acquired will be recorded as goodwill. Any identified intangible asset may be amortized by charges to operations under U.S. GAAP.

MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES OF THE MERGERS

The following discussion is a summary of certain U.S. federal income tax consequences of the mergers to U.S. holders (as defined below) of Bremer common stock that exchange their shares of Bremer common stock for shares of Old National common stock and cash in the mergers. The following summary is based upon the provisions of the Code, its legislative history, existing and proposed U.S. Treasury Regulations promulgated thereunder, rulings and other administrative pronouncements issued by the Internal Revenue Service (the “IRS”) and judicial decisions, all as currently in effect as of the date of this proxy statement/prospectus, and all of which are subject to change, and to differing interpretations possibly with retroactive effect. Any such change or interpretation could affect the accuracy of the statements and conclusions set forth in this discussion.

This discussion addresses only U.S. holders who hold Bremer common stock as a capital asset within the meaning of Section 1221 of the Code (generally, property held for investment). This discussion assumes the mergers will be consummated in accordance with the merger agreement as described in this proxy statement/prospectus. Holders of Bremer common stock that are not U.S. holders should consult their own tax advisors as to the tax consequences of the mergers. This discussion does not address any U.S. federal tax consequences other than income tax consequences (such as estate, gift or other non-income tax consequences) or any state, local or foreign income or non-income tax consequences, or under any U.S. federal laws other than those pertaining to income tax. In addition, this discussion does not purport to be a complete analysis of all of the U.S. federal income tax consequences (such as the Medicare contribution tax on net investment income, any withholding considerations under the Foreign Account Tax Compliance Act of 2010 (including the Treasury regulations issued thereunder and intergovernmental agreements entered into pursuant thereto or in connection therewith) or any alternative minimum tax) that may be relevant to U.S. holders in light of their particular circumstances and does not address all of the U.S. federal income tax consequences that may be relevant to particular holders of Bremer common stock that are subject to special rules, including, but not limited to:

•

financial institutions;

•

partnerships or other pass-through entities (or other entities or arrangements treated as partnerships or pass-through entities for U.S. federal income tax purposes) or investors in such partnerships or pass-through entities;

•

mutual funds;

•

S corporations or investors in such S corporations;

•

insurance companies;

•

tax-exempt organizations or governmental organizations;

•

dealers or brokers in securities or currencies;

•

traders in securities that elect to use a mark-to-market method of accounting;

•

persons that immediately before the mergers directly, indirectly or constructively owned at least 5% of all Bremer common stock (by vote or value);

•

regulated investment companies;

•

real estate investment trusts;

TABLE OF CONTENTS

•

tax-qualified retirement plans;

•

persons that hold Bremer common stock as part of a straddle, hedge, constructive sale or conversion transaction;

•

persons subject to special tax accounting rules as a result of any item of gross income with respect to the stock being taken into account in an applicable financial statement;

•

holders who exercise dissenters’ rights;

•

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

•

holders who acquired their shares of Bremer common stock through the exercise of an employee stock option, in connection with a performance-based or other restricted stock unit or otherwise as compensation, or who receive shares of Old National common stock that are subject to vesting;

•

holders who hold their shares as “qualified small business stock” for the purposes of Section 1045 or Section 1202 of the Code; and

•

persons that have a functional currency other than the U.S. dollar.

If a partnership or pass-through entity (or other entity or arrangement classified as a partnership or pass-through entity for U.S. federal income tax purposes) holds Bremer common stock, the tax treatment of a partner in such partnership generally will depend upon the status of the partner, the activities of the partnership and certain determinations made at the partner level. Partnerships for U.S. federal income tax purposes and partners in such a partnership should consult their tax advisors about the tax consequences of the mergers to them.

For purposes of this discussion, the term “U.S. holder” means a beneficial owner of Bremer common stock that is, or is treated for U.S. federal income tax purposes as, any of the following:

•

an individual who is a citizen or resident of the United States;

•

a corporation (or any other entity treated as a corporation) created or organized in or under the laws of the United States or of any state or the District of Columbia;

•

a trust that (i) is subject to the primary supervision of a court within the United States and all substantial decisions of which are subject to the control of one or more U.S. persons (as defined in Section 7701(a)(30) of the Code) or (ii) has a valid election in effect under applicable U.S. Treasury Regulations to be treated as a United States person; or

•

an estate, the income of which is subject to U.S. federal income taxation regardless of its source.

No rulings have been, or will be, sought by Bremer or Old National from the IRS with respect to the mergers, and there can be no assurance that the IRS or a court will not take a contrary position regarding the tax consequences described in this proxy statement/prospectus. The actual tax consequences of the mergers to you may be complex and will depend on your specific situation and on factors that are not within the control of Bremer or Old National.

All Bremer shareholders should consult their own tax advisors as to the tax consequences of the mergers in their particular circumstances, including the applicability and effect of U.S. federal, state, local or non-U.S. income or other tax laws.

The parties intend for the mergers, taken together, to qualify as a “reorganization” within the meaning of Section 368(a) of the Code. It is a condition to Old National’s obligation to complete the mergers that Old National receive an opinion from Squire Patton Boggs (US) LLP, as of the closing date, to the effect that the mergers, taken together, will qualify as a “reorganization” within the meaning of Section 368(a) of the Code. Additionally, it is a condition to Bremer’s obligation to complete the mergers that Bremer receive an opinion from Wachtell Lipton Rosen & Katz, as of the closing date, to the effect that the mergers, taken together, will qualify as a “reorganization” within the meaning of Section 368(a) of the Code (collectively, the “opinions”). The opinions will be subject to customary qualifications and assumptions, including that the mergers will be completed according to the terms of the merger agreement. One critical factual assumption is that at least 40 percent of the value of the merger consideration received in exchange for Bremer’s common

TABLE OF CONTENTS

stock in the first step merger will consist of Old National common stock, taking into account any cash consideration received (including any cash paid in lieu of fractional shares of Old National common stock) and cash payable to holders of dissenting shares.

These opinions will also be based on the assumption that the representations included in the representation letters of Bremer and Old National, are, as of the effective time of the mergers, true and complete without qualification and that the representation letters of Bremer and Old National are executed by appropriate and authorized officers of Bremer and Old National. Neither of the opinions described above will be binding on the IRS. Bremer and Old National have not sought and will not seek any ruling from the IRS regarding any matters relating to the mergers, and, as a result, there can be no assurance that the IRS will not assert, or that a court would not sustain, a position contrary to any of the conclusions set forth below. If any of the representations, warranties, covenants or assumptions upon which the opinions described above are based are inconsistent with the actual facts, or if any condition contained in the merger agreement and affecting these opinions is breached or is waived by any party, the U.S. federal income tax consequences of the mergers could be adversely affected. Accordingly, each holder of Bremer common stock should consult his, her or its tax advisor with respect to the particular tax consequences of the mergers to such holder.

Tax Consequences to U.S. Holders Generally

If the mergers, taken together, qualify as a “reorganization” within the meaning of Section 368(a) of the Code, the U.S. federal income tax consequences to U.S. holders of the mergers are as follows:

•

a U.S. holder will recognize gain in an amount equal to the lesser of (i) the cash received (other than cash paid in lieu of a fractional share of Old National common stock) received by the holder and (ii) the gain realized. The gain realized is the excess, if any, of (a) the sum of the amount of cash received by the U.S. holder in the mergers (other than cash paid in lieu of a fractional share of Old National common stock) and the fair value of the Old National common stock received, over (b) the U.S. holder’s adjusted tax basis in the Bremer common stock surrendered in the mergers;

•

a U.S. holder will not recognize any loss upon the exchange of Bremer common stock for Old National common stock and cash in the mergers (other than with respect to any cash received in lieu of a fractional share of Old National common stock);

•

a U.S. holder’s aggregate tax basis in the Old National common stock received in the mergers (including fractional shares deemed received and deemed redeemed as described below) will equal the holder’s tax basis in the Bremer common stock surrendered therefor in the mergers, reduced by any cash received (other than any cash paid in lieu of a fractional share of Old National common stock), and increased by the amount of gain the holder recognizes on the exchange (regardless of whether such gain is classified as capital gain or dividend income, as discussed below, but excluding any gain recognized with respect to cash paid in lieu of a fractional share of Old National common stock);

•

a U.S. holder’s holding period in the Old National common stock received by such holder in the mergers will include the holder’s holding period in the Bremer common stock surrendered in exchange therefor; and

•

a U.S. holder who receives cash in lieu of a fractional share of Old National common stock will be treated as having received the fractional share pursuant to the mergers and then as having exchanged that fractional share with Old National for cash in a redemption transaction. Such holder will generally recognize gain or loss equal to the difference between the amount of cash received and such holder’s tax basis allocated to such fractional share.

If a U.S. holder acquired different blocks of shares of Bremer common stock (a block of stock is stock of the same class acquired on the same day at the same price per share) at different times or different prices, any gain or loss may be determined separately for each block of shares and such U.S. holder’s basis and holding period in its shares of Old National common stock may be determined with reference to each block of shares of Bremer common stock. Each holder should consult his, her or its tax advisor regarding the manner in which the cash consideration and stock consideration should be allocated among different blocks

of shares of Bremer common stock surrendered and the determination of the tax bases and holding periods of the Old National common stock received.

Any gain recognized in the mergers generally will be long-term capital gain if the U.S. holder held the Bremer common stock surrendered in the mergers for more than one year at the effective time of the first step merger, and otherwise generally will be short-term capital gain. In the case of a U.S. holder that holds Bremer common stock with differing tax bases and/or holding periods, the preceding rules must be applied separately to each block of shares of Bremer common stock (i.e., Bremer common stock of the same class acquired on the same day at the same price per share). Generally, long-term capital gain of individuals and other non-corporate U.S. holders currently is eligible for preferential U.S. federal income tax rates. In certain circumstances, if a U.S. holder actually or constructively owns Old National common stock other than Old National common stock received pursuant to the transaction, the recognized gain could be treated as having the effect of the distribution of a dividend under the tests set forth in Section 302 of the Code, in which case such gain would be treated as dividend income to the extent of such U.S. holder’s ratable share of Bremer’s undistributed earnings and profits. To the extent, if any, that the recognized gain is treated as dividend income, noncorporate U.S. holders generally would be taxed on such amounts at the preferential rates applicable to long-term capital gain. Because the possibility of dividend treatment depends upon the particular circumstances of a U.S. holder, including the application of certain constructive ownership rules, U.S. holders should consult their tax advisors regarding the potential application of the foregoing rules to their particular circumstances.

Information Reporting and Backup Withholding

In general, information reporting requirements may apply to cash payments made to U.S. holders in connection with the mergers, unless an exemption applies. Backup withholding (currently, at a rate of 24%) may apply to amounts subject to information reporting if the applicable shareholder fails to provide an accurate taxpayer identification number, fails to report all interest and dividends required to be shown on its U.S. federal income tax returns or otherwise fails to establish an exemption from backup withholding. U.S. holders can claim a credit against their U.S. federal income tax liability for the amount of any backup withholding and a refund of any excess, provided that all required information is timely provided to the IRS.

THE DISCUSSION ABOVE IS A GENERAL SUMMARY. IT DOES NOT COVER ALL TAX MATTERS THAT MAY BE APPLICABLE OR OF IMPORTANCE TO A PARTICULAR HOLDER. THE TAX CONSEQUENCES OF THE MERGERS WILL DEPEND ON A HOLDER’S SPECIFIC SITUATION. EACH HOLDER SHOULD CONSULT HIS, HER OR ITS TAX ADVISOR ABOUT THE TAX CONSEQUENCES TO SUCH HOLDER OF THE TRANSACTION IN LIGHT OF THE HOLDER’S OWN CIRCUMSTANCES, AS WELL AS THE APPLICABILITY AND EFFECT OF ANY U.S. FEDERAL, STATE, LOCAL, FOREIGN OR OTHER TAX LAWS.

DESCRIPTION OF OLD NATIONAL SECURITIES

As a result of the mergers, Bremer shareholders who receive shares of Old National common stock in the mergers will become shareholders of Old National. Your rights as a shareholder of Old National will be governed by the IBCL, the Old National articles of incorporation and the Old National bylaws. The following briefly summarizes the material terms of Old National common stock that will be issued in connection with the mergers. You are urged to read the applicable provisions of the IBCL, the Old National articles of incorporation and the Old National bylaws, which will be sent to shareholders of Bremer upon request. For further information, see “Where You Can Find More Information.”

Common Stock

Authorized Common Stock

As of January 28, 2025, Old National’s authorized common stock, without par value, was 600,000,000 shares, of which 318,986,101 shares were issued and outstanding. Shares of Old National common stock, when issued in accordance with the terms of the merger agreement, will be validly issued, fully paid and non-assessable.

General

Voting Rights

The holders of Old National common stock are entitled to one vote for each share of common stock held of record by them on all matters to be voted on by shareholders, except:

(a)

shares of common stock are not entitled to a vote if such shares are owned, directly or indirectly, by another corporation and Old National owns, directly or indirectly, a majority of the shares entitled to vote for directors of such corporation; provided, however, such limitation on voting does not limit Old National’s power to vote shares of Old National common stock held by Old National in or for an employee benefit plan or in any other fiduciary capacity; or

(b)

to the extent shares are control shares acquired in a control share acquisition within the meaning of Chapter 42 of the IBCL, which such shares have voting rights only to the extent granted by resolution approved by Old National shareholders in accordance with Section 23-1-42-9 of the IBCL.

The holders of Old National common stock are not entitled to cumulative voting rights. Under the IBCL, directors are elected by a plurality of the votes cast by shares entitled to vote in an election at a meeting at which a quorum is present. Old National bylaws provide that for all other shareholder votes, when a quorum is present at any meeting, the vote of a majority of the stock having voting power present or represented by proxy shall decide any question brought before such meeting, unless the question is one upon which, by express provision of the IBCL, or the Old National articles of incorporation and the Old National bylaws, a greater vote is required, in which case such express provision shall govern and control the decision of such question.

Dividends

Subject to the rights of any series of preferred stock authorized by the Old National board of directors as provided by the Old National articles of incorporation, the holders of Old National common stock are entitled to dividends as and when declared by the Old National board of directors out of funds legally available for the payment of dividends.

Liquidation

In the event of a liquidation or dissolution of Old National, subject to the rights of any outstanding series of preferred stock, the holders of common stock are entitled to share in all assets remaining for distribution to common shareholders according to their interests.

TABLE OF CONTENTS

Other Rights

Holders of Old National common stock have no preemptive or other subscription rights, and shares of common stock are not subject to any further calls or assessments by Old National. There are no redemption or conversion rights or sinking fund provisions applicable to the shares of Old National common stock.

Listing

Old National’s common stock is listed on the NASDAQ Stock Exchange under the symbol “ONB”. Old National’s transfer agent for its common stock is Continental Stock Transfer & Trust Company.

Forward Sale Agreements

Old National entered into two forward sale agreements on November 25, 2024 with the forward purchaser, relating to an aggregate of 21,904,762 shares of Old National common stock. In connection with the forward sale agreements, the forward purchaser or its affiliate borrowed from third parties an aggregate of 21,904,762 shares of Old National common stock.

The forward sale price was initially $20.16 per share, which is the price at which the underwriters agreed to buy the shares of Old National common stock offered. The forward sale price is subject to adjustment on a daily basis based on a floating interest rate factor equal to the specified rate less a spread and will be decreased on each of the dates specified in the forward sale agreements by amounts related to expected dividends on shares of Old National common stock during its term. The forward sale price will also be subject to decrease if the cost to the forward purchaser (or its affiliate) of borrowing a number of shares of Old National common stock underlying the forward sale agreements exceeds a specified amount. If the specified rate is less than the spread on any day, the interest rate factor will result in a daily reduction of the forward sale price.

Before any issuance of shares of Old National common stock upon physical or net share settlement of the forward sale agreements, Old National expects that the shares issuable upon settlement of the forward sale agreements will be reflected in Old National’s diluted earnings per share calculation using the treasury stock method. Under this method, the number of shares of Old National common stock used in calculating diluted earnings per share is deemed to be increased by the excess, if any, of the number of shares of Old National common stock that would be issued upon full physical settlement of the forward sale agreements over the number of shares of Old National common stock that could be purchased by Old National in the market (based on the average market price of Old National common stock during the applicable reporting period) using the proceeds receivable upon full physical settlement (based on the adjusted forward sale price at the end of the reporting period).

Consequently, before physical or net share settlement of the forward sale agreements and subject to the occurrence of certain events, Old National anticipates that there will be no dilutive effect on its earnings per share except during periods when the average market price of shares of Old National common stock is above the applicable adjusted forward sale price, which was initially $20.16 per share, subject to increase or decrease based on the specified rate less a spread, and subject to price adjustment and other provisions of the forward sale agreements, including a decrease based on amounts related to expected dividends on Old National common stock on dates specified in the forward sale agreements and if the cost to the forward purchaser (or its affiliate) of borrowing a number of shares of Old National common stock underlying the forward sale agreements exceeds a specified amount. However, if Old National decides to physically settle or net share settle the forward sale agreements, then delivery of shares of Old National common stock to the forward purchaser on any such physical or (to the extent Old National is obligated to deliver shares of its common stock) net share settlement of the forward sale agreements would result in dilution to Old National’s earnings per share.

The forward purchaser has the right to accelerate the forward sale agreements and require Old National to physically settle on a date specified by the forward purchaser if:

•

the forward purchaser (or its affiliate) (i) is unable to borrow a number of shares of Old National common stock equal to the number of shares of Old National common stock underlying the forward sale agreements because of the lack of sufficient shares being made available for share borrowing

TABLE OF CONTENTS

by lenders or (ii) would incur a stock loan rate greater than the rate specified in the forward sale agreements to continue to borrow such shares;

•

certain regulatory ownership thresholds applicable to the forward purchaser, its affiliates and other persons who may form a beneficial share ownership group or whose ownership positions would be aggregated with the forward purchaser are exceeded;

•

Old National declares any dividend or distribution on Old National common stock that constitutes an extraordinary dividend or is payable in (i) cash in excess of a specified amount (other than extraordinary dividends), (ii) securities of another company owned (directly or indirectly) by Old National as a result of a spin-off or similar transaction or (iii) any other type of securities (other than Old National common stock), rights, warrants or other assets for payment at less than the prevailing market price, as reasonably determined by the forward purchaser;

•

there is an announcement of any event or transaction that, if consummated, would result in certain extraordinary events (as such term is defined in the forward sale agreements and that includes certain mergers (other than the mergers or the bank merger) and tender offers and the delisting of Old National common stock); or

•

certain other events of default, termination events or other specified events occur, including, among other things, any material misrepresentation made by Old National in connection with entering into the forward sale agreements or the occurrence of a hedging disruption or a change in law (as such terms are defined in the forward sale agreements).

The forward purchaser’s decision to exercise its right to accelerate the settlement of the forward sale agreements will be made irrespective of Old National’s need for capital. In such cases, Old National could be required to issue and deliver shares of Old National common stock under the physical settlement provisions of the forward sale agreements irrespective of Old National’s capital needs, which would result in dilution to Old National’s earnings per share and return on equity. In addition, upon certain events of bankruptcy or insolvency related to Old National, the forward sale agreements will terminate without further liability of any party. Following any such termination, Old National would not issue any shares of Old National common stock or receive any proceeds pursuant to the forward sale agreements.

Old National expects to physically settle the forward sale agreements (by the delivery of shares of Old National common stock) and receive proceeds from the sale of those shares of Old National common stock upon one or more forward settlement dates within approximately 12 months from the date of the forward sale agreements. Old National may also elect cash settlement or net share settlement for all or a portion of its obligations under the forward sale agreements. Upon physical settlement or, if Old National so elects, net share settlement of the forward sale agreements, delivery of shares of Old National common stock in connection with such physical settlement or (to the extent Old National is obligated to deliver shares of its common stock) net share settlement will result in dilution to Old National’s earnings per share and return on equity. If Old National elects cash settlement or net share settlement with respect to all or a portion of the shares of its common stock underlying the forward sale agreements, then Old National expects that the forward purchaser (or an affiliate thereof) will purchase a number of shares of Old National common stock necessary to satisfy its or its affiliate’s obligation to return the shares of Old National common stock borrowed from third parties in connection with sales of shares of Old National common stock related to the forward sale agreements and, if applicable in connection with net share settlement, to deliver shares of Old National common stock to Old National. If the market value of Old National common stock at the time of such purchase (as determined pursuant to the terms of the forward sale agreements) is above the forward sale price under the forward sale agreements at that time, then Old National would pay or deliver, as the case may be, to the forward purchaser under the forward sale agreements, an amount in cash, or a number of shares of Old National common stock with a market value (as determined pursuant to the terms of the forward sale agreements), equal to such difference. Any such difference could be significant. Conversely, if the market value of Old National’s common stock at the time of such purchase (as determined pursuant to the terms of the forward sale agreements) is below the forward sale price under the forward sale agreements at that time, the forward purchaser will pay or deliver, as the case may be, to Old National under the forward sale agreements, an amount in cash, or a number of shares of Old National common stock with a market value (as determined pursuant to the terms of the forward sale agreements), equal to such difference.

TABLE OF CONTENTS

In addition, the purchase of shares of Old National common stock in connection with the forward purchaser or its affiliate unwinding its hedge positions could cause the price of Old National common stock to increase over such time (or reduce or prevent a decrease over such time), thereby increasing the amount of cash Old National would owe to the forward purchaser (or decreasing the amount of cash that the forward purchaser would owe Old National) upon a cash settlement of the forward sale agreements or increasing the number of shares of Old National common stock Old National would deliver to the forward purchaser (or decreasing the number of shares of Old National common stock that the forward purchaser would deliver to Old National) upon net share settlement of the forward sale agreements. Old National will not be able to control the manner in which the forward purchaser (or its affiliate) unwinds its hedge positions.

Indiana Law and Certain Provisions of the Old National Articles of Incorporation; Anti-Takeover Measures

Articles of Incorporation

The Old National articles of incorporation currently authorize the issuance of 600,000,000 shares of common stock and 2,000,000 shares of preferred stock. Within the limits of applicable law and the listing rules of the NASDAQ Stock Exchange, these shares are available to be issued, without prior shareholder approval, in classes with relative rights, privileges and preferences determined for each class by the Old National board of directors.

The Old National articles of incorporation also provide that certain business combinations may, under certain circumstances, require approval of more than a simple majority of Old National’s issued and outstanding shares, and require a vote of not less than eighty percent (80%) of the outstanding shares of common stock for the amendment of certain significant provisions of the Old National articles of incorporation.

Additionally, the Old National articles of incorporation provide that the Old National board of directors will consider non-financial factors that it deems relevant when evaluating a business combination. Any amendment of this provision requires a vote of not less than eighty percent (80%) of the outstanding shares of common stock.

Finally, the Old National articles of incorporation provide that any person or group of persons who acquires 15% or more of Old National’s then outstanding common stock must pay an amount at least equal to the highest percent over market value paid for shares already held by such person or group when acquiring additional shares. Any amendment of this provision requires a vote of not less than eighty percent (80%) of the outstanding shares of common stock.

These provisions in the Old National articles of incorporation are designed to encourage potential acquirors to negotiate with the Old National board of directors to preserve for shareholders Old National’s value in the event of a takeover attempt. These provisions reduce the likelihood that a potential acquiror who is unwilling to pay a market premium determined by the board to be sufficient will attempt to acquire shares of Old National common stock by means of an open market accumulation, front-end loaded tender offer or other coercive or unfair takeover tactic. These provisions in the Old National articles of incorporation would ensure that Old National, its shareholders and the other stakeholders would be protected from certain takeover attempts, or the acquisition of a substantial block of equity, on terms that may be less favorable generally than would be available in transactions negotiated with and approved by the board.

Indiana Law

Chapters 42 and 43 of the IBCL may be deemed to have certain anti-takeover effects by prescribing, in the case of Chapter 42, certain voting requirements in instances in which a person acquires shares of Old National in excess of certain thresholds or proscribing, in the case of Chapter 43, certain transactions between Old National and an “interested stockholder” (defined generally as a person beneficially owning 10% or more of a corporation’s outstanding voting stock) during the five-year period following the time such person became an interested stockholder.

In addition, Chapter 35 of the IBCL provides that in taking or declining to take any action, or in making or declining to make any recommendation to the shareholders of an Indiana corporation with

TABLE OF CONTENTS

respect to any matter, a board of directors may, in its discretion, consider both the short term and long term best interests of the corporation, taking into account, and weighing as the directors deem appropriate, the effects thereof on the corporation’s shareholders and the other corporate constituent groups and interests, as well as any other factors deemed pertinent by the directors. As a result, by expanding the factors that may be considered relevant by the directors in assessing a takeover proposal, this provision could be deemed to have certain anti-takeover effects.

COMPARISON OF SHAREHOLDERS’ RIGHTS

If the mergers are completed, Bremer shareholders will receive shares of Old National common stock in the mergers. Old National is organized under the laws of the State of Indiana, and Bremer is organized under the laws of the State of Minnesota. The following is a summary of the material differences between (1) the current rights of Bremer shareholders under the Bremer articles of incorporation, the Bremer bylaws and the Bremer plan of reorganization, and (2) the current rights of Old National shareholders under the Old National articles of incorporation and the Old National bylaws.

Old National and Bremer believe that this summary describes the material differences between the rights of Old National shareholders as of the date of this proxy statement/prospectus and the rights of Bremer shareholders as of the date of this proxy statement/prospectus; however, it does not purport to be a complete description of those differences. Copies of Old National’s governing documents have been filed with the SEC. To find out where copies of these documents can be obtained, see “Where You Can Find More Information.”

As of the record date for the special meeting of Bremer shareholders, there were 1,924,785 shares of Bremer Class A common stock outstanding and 10,075,000 shares of Bremer Class B common stock outstanding. The Bremer articles of incorporation provide that Bremer may not issue any additional shares of Bremer Class A common stock if such an issuance would reduce the remaining authorized but unissued shares of Bremer Class A common stock to an amount that is less than the total amount of shares of outstanding Bremer Class B common stock. Except with respect to voting and conversion rights, the Bremer Class A common stock and Bremer Class B common stock have the same rights and privileges and rank equally, share ratably and are identical in all respects as to all matters, including the right to share equally in any dividends declared Bremer and the right to share equally in liquidation proceeds.	Old National is authorized to issue up to (i) 600,000,000 shares of common stock, without par value and (ii) 2,000,000 shares of preferred stock, without par value.

The Old National board of directors consists of one class. All directors serve a one-year term, expiring at the next annual meeting of shareholders, or until their respective successors are duly elected and qualified or their earlier resignation, death, or removal.
Removal of Directors	The Bremer bylaws provide that shareholders may remove any or all of the directors, with or without cause, upon the affirmative vote of shareholders holding a majority of shares entitled to vote at an election of directors. Any director named by the board of directors to fill a vacancy may be removed at any time, without or without cause, by the affirmative vote of a majority of the remaining directors if the shareholders have not elected directors in the interim between the time of the appointment to fill such vacancy and the time of the removal.	The Old National bylaws provide that directors may be removed, with or without cause, only by (i) the affirmative vote of the holders of not less than two-thirds of the issued and outstanding shares of common stock entitled to vote on the removal, or (ii) the affirmative vote of not less than two-thirds of the actual number of directors elected and qualified and then in office.
Vacancies on the Board of Directors	The Bremer bylaws provide that the affirmative vote of a majority of remaining directors then in office (even if less than a quorum) may fill a vacancy resulting from the death, resignation, removal or disqualification of a director. A vacancy resulting from an increase in the size of the board of directors may be filled by a majority of the directors then in office at the time of such increase. A director elected to fill a vacancy will be a director until such director’s successor is elected by the Bremer shareholders at their next regular or special meeting.	The Old National bylaws provide that a vacancy occurring in the board of directors for any reason may be filled for the remaining portion of the term by the affirmative vote of a majority of the remaining directors, whether or not the remaining directors constitute a quorum.

A shareholder’s written suggestion must set forth (i) the name and address of the shareholder making the suggestion; (ii) the number and class of shares owned by the shareholder; (iii) the name, address, and age of the nominee for election as director; (iv) the nominee’s principal occupation during the five years preceding the date of the suggestion; (v) all other information concerning the nominee which would be required in the proxy statement used to solicit proxies for the election of the nominee; (vi) a consent of the nominee to serve as director of Old National, if elected; and (vii) such other information as the corporate governance and nominating committee may reasonably request. The Old National board of directors, after considering the recommendations of the corporate governance and nominating committee, shall have the sole authority for nominating persons to stand for election as directors at any meeting of shareholders.
Limitation of Liability for Officers and Directors	The Bremer articles of incorporation eliminate a director’s personal liability to the fullest extent permitted by the MBCA. The MBCA provides that a director’s personal liability to the corporation or its shareholders for monetary damages for breach of fiduciary duty as a director may be eliminated except the articles of incorporation may not eliminate or limit the liability of a director: (i) for any breach of the director’s duty of loyalty to the corporation or its shareholders, (ii) for acts or omissions not in good faith or that involve intentional misconduct or a knowing violation of law, (iii) certain illegal distributions or	The Old National articles of incorporation and the Old National bylaws do not provide for any limitation of liability for officers and directors. However, Chapter 35 of the IBCL provides that a director is not liable for any action taken as a director, or any failure to take any action, regardless of the nature of the alleged breach of duty, including alleged breaches of the duty of care, the duty of loyalty, and the duty of good faith, unless (i) the director has breached or failed to perform the duties of the director’s office in compliance with the IBCL and (ii) the breach or failure to perform constitutes willful

Old National’s officers and directors are indemnified under Indiana law, the Old National articles of incorporation and the Old National bylaws against certain liabilities.
Indemnification of Officers and Directors	The Bremer bylaws provide that Bremer shall indemnify such persons, for such expenses and liabilities as permitted by §302A.521 of the MBCA. The MBCA provides that a corporation will indemnify a person made or threatened to be made a party to a proceeding by reason of the former or present capacity as a director, officer or employee, or such person who is or was serving at the request of the corporation, as a director, officer, partner, trustee, governor, manager, employee, or agent of another organization or employee benefit plan, against judgments, penalties, fines, settlements, and reasonable expenses, including attorneys’ fees and disbursements, incurred by the person in connection with the proceeding, if, with respect to the acts or omissions of the person complained of in the proceeding, the person: (i) has not been indemnified by another organization or employee benefit plan for the same judgments, penalties, fines, settlements, and reasonable expenses, (ii) acted in good faith, (iii) received no improper personal benefit and the MBCA section with respect to director conflicts of interests, if applicable, has been satisfied, (iv) in the case of a criminal proceeding, had no reasonable cause to believe the conduct was unlawful, and (v) in the case of acts or omissions by directors, officers and employees, reasonably believed that the conduct was in	The Old National articles of incorporation require Old National to indemnify its officers and directors to the fullest extent authorized by the IBCL and to pay for or reimburse reasonable expenses incurred before the final disposition of the proceeding as authorized by the IBCL. The Old National articles of incorporation also authorize Old National to maintain insurance at its expense to protect itself and any of its directors, officers, employees or agents or those of another corporation, partnership, joint venture, trust, or other entity against expense, liability or loss, whether or not Old National would have the power to indemnify such person against such expense, liability or loss under the IBCL. Old National currently maintains directors’ and officers’ liability insurance. Insofar as indemnification for liabilities arising under the Securities Act of 1933, as amended (the “Securities Act”) may be permitted to Old National directors, officers and controlling persons pursuant to the foregoing provisions, or otherwise, Old National has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable.

	the best interests of the corporation. The MBCA provides that such persons are entitled, to payment or reimbursement by the corporation of reasonable expenses, including attorneys’ fees and disbursements, incurred by the person in advance of the final disposition of the proceeding, (i) upon receipt by the corporation of a written affirmation by the person of a good faith belief that the criteria for indemnification set forth in the MBCA have been satisfied and a written undertaking by the person to repay all amounts so paid or reimbursed by the corporation, if it is ultimately determined that the criteria for indemnification have not been satisfied, and (ii) after a determination that the facts then known to those making the determination would not preclude indemnification under the MBCA.
Amendments to Organizational Documents	The Bremer articles of incorporation may be amended pursuant to the procedures specified in the MBCA. Pursuant to the MBCA, an amendment to the Bremer articles of incorporation may be submitted to the Bremer shareholders by a resolution approved by the affirmative vote of a majority of the directors present or by a shareholder or shareholders holding three percent or more of the voting power of the shares entitled to vote.

Transfer of Shares	Bremer purchase option In the event that a holder of Bremer Class A common stock proposes to dispose of or transfer its stock (or any interest therein) to a third party or upon the death, retirement or termination of employment with Bremer of such holder, such holder must provide written notice to Bremer of such event, and Bremer or its assignee will have the option to purchase the Bremer Class A common stock for a cash purchase price equal to its book value per share as shown on Bremer’s consolidated balance sheet as of the last day of the immediately preceding fiscal quarter (the “Bremer purchase option”). The Bremer purchase option commences on the date of the event giving rise to the Bremer purchase option and continues until 60 days after Bremer receives written notice of the event giving rise to the Bremer purchase option.

			exercises its right, or such longer period as reasonably required to obtain any necessary regulatory approvals. If Bremer or its assignee fails to exercise the Bremer purchase option within the option period, the holder of the Bremer Class A common stock may transfer the Bremer Class A common stock in their sole discretion. Transferee’s option In the event of a sale of all or substantially all of the shares of Bremer Class B common stock held by the Otto Bremer Trust, the Otto Bremer Trust, its assignee or the transferee of such stock has the right (the “transferee’s option”), to purchase all shares of Bremer Class A common stock that are outstanding at a cash purchase price equal to the greater of the below: the book value per share as set forth on Bremer’s consolidated balance sheet as of the day of the immediately preceding fiscal quarter; the average price per share realized by the Otto Bremer Trust for the sale of its Bremer Class A common stock and Bremer Class B common stock; or with respect to any Bremer Class A common stock owned by the Bremer ESOP or any stock owned by a former Bremer ESOP participant which stock was distributed from the Bremer ESOP to such participant within the preceding 15 months, the fair market value of the stock as established by its most recent annual appraisal. The transferee’s option is effective upon written notice of exercise of the option to the holders of Bremer Class A common stock on or subsequent to the date upon

			which the Otto Bremer Trust and the transferee execute a definitive purchase agreement for the Bremer Class B common stock. The period to exercise the transferee’s option will continue for 60 days following the effective date of the sale of Bremer Class B common stock. The purchase and sale of Bremer Class A common stock pursuant to the transferee’s option must occur within 120 days following the exercise of the transferee’s option, or such longer period as reasonably required to obtain any necessary regulatory approvals. Put option to transferee In the event of a sale of all or substantially all of the shares of Bremer Class B common stock held by the Otto Bremer Trust, each holder of Bremer Class A common stock has the right (the “put option to transferee”), to sell all of its Bremer Class A common stock shares to the Otto Bremer Trust or the Otto Bremer Trust’s designated assignee for a total cash purchase price per share equal to the average sales price per share realized by the Otto Bremer Trust for the sale of its Bremer Class A common stock and Bremer Class B common stock. The put option to transferee is effective commencing with the date on which the Otto Bremer Trust and its transferee execute an agreement providing for the sale of the Bremer Class B common stock and will continue for 30 days following the date on which the holder of Bremer Class A common stock receives written notice from the Otto Bremer Trust of the event giving rise to the put option to transferee. Holders of Bremer Class A common stock that wish to exercise their put option to transferee must provide written notice to the Otto Bremer

			Trust, its assignee or the transferee of such intent during the option period. The closing of the purchase and sale of Bremer Class A common stock pursuant to the put option to transferee (as determined by the Otto Bremer Trust, its assignee or transferee as the case may be) must occur on or before 60 days following the closing date of the sale of Bremer Class B common stock by the Otto Bremer Trust, or such later date as reasonably required to obtain any necessary regulatory approvals. Put option to Bremer Upon the occurrence of certain events described below, which we call “put events”, each holder of Bremer Class A common stock has the right, which we call the “put option to Bremer”, to require Bremer or Bremer’s assignee to repurchase all shares of Bremer Class A common stock then owned. The put option to Bremer arises from the following put events: for a shareholder who is a former Bremer ESOP participant, at the affirmative election of the shareholder anytime within 15 months after each distribution of Bremer Class A common stock from the Bremer ESOP to such former participant, except that the put option to Bremer only applies to the Bremer Class A common stock received pursuant to such distribution (a “Bremer ESOP distribution put event”); and for any shareholder of Bremer Class A common stock who is a Bremer employee, upon the death, “permanent disability” or retirement at “normal retirement age” (both as defined in the Bremer ESOP) of such shareholder’s Bremer Class A common stock (a “death, disability or retirement put

			event”). The put option to Bremer may be exercised upon written notice to Bremer within 90 days following the occurrence of a put event. The purchase price for the Bremer Class A common stock subject to the put option to Bremer will be in cash in the following amounts: for Bremer Class A common stock sold pursuant to a put option to Bremer arising from a Bremer ESOP distribution put event, the price per share will be equal to the fair market value as established by the most recent annual appraisal; and for Bremer Class A common stock sold pursuant to a put option to Bremer arising from a death, disability or retirement put event, the price per share will be equal to the book value per share as shown on Bremer’s consolidated financial statements as of the last day of the immediately preceding fiscal quarter. The closing of the purchase and sale of Bremer Class A common stock contemplated by the put option to Bremer must occur within 120 days following the shareholder’s exercise of its rights under the put option, or such longer period as is reasonably required to obtain any necessary regulatory approvals. Bremer is not required to repurchase any Bremer Class A common stock pursuant to the exercise of the put option to Bremer if the consideration for such purchase, when added to the consideration paid by Bremer for all previous purchases of Bremer Class A common stock during the preceding 12-month period, would exceed 10% of Bremer’s net worth as of the date of purchase.

Report of Independent Auditors

The Board of Directors and Shareholders
Bremer Financial Corporation

Opinion

We have audited the consolidated financial statements of Bremer Financial Corporation (the Company), which comprise the consolidated balance sheets as of December 31, 2023 and 2022, and the related consolidated statements of income, comprehensive income, changes in shareholders’ equity, and cash flows for the years then ended, and the related notes (collectively referred to as the “financial statements”).

In our opinion, the accompanying financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2023 and 2022, and the results of its operations and its cash flows for the years then ended in accordance with accounting principles generally accepted in the United States of America.

We also have audited, in accordance with auditing standards generally accepted in the United States of America, the Company’s internal control over financial reporting, including internal control over the preparation of regulatory financial statements, in accordance with the instructions to the Consolidated Financial Statements for Bank Holding Companies (Form FR Y-9C) as of December 31, 2023, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria) and our report dated March 26, 2024 expressed an unmodified opinion thereon.

Basis for Opinion

We conducted our audits in accordance with auditing standards generally accepted in the United States of America (GAAS). Our responsibilities under those standards are further described in the Auditor’s Responsibilities for the Audit of the Financial Statements section of our report. We are required to be independent of the Company and to meet our other ethical responsibilities in accordance with the relevant ethical requirements relating to our audits. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our audit opinion.

Adoption of ASU 2016-13, Financial Instruments — Credit Losses

As discussed in Note 3 to the financial statements, in 2023 the Company changed its method of accounting for credit losses as a result of the adoption of the amendments to the FASB Accounting Standards Codification resulting from Accounting Standards Update (ASU) No. 2016-13, Financial Instruments — Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, and the related amendments. Our opinion is not modified with respect to this matter.

Responsibilities of Management for the Financial Statements

Management is responsible for the preparation and fair presentation of the financial statements in accordance with accounting principles generally accepted in the United States of America, and for the design, implementation, and maintenance of internal control relevant to the preparation and fair presentation of financial statements that are free of material misstatement, whether due to fraud or error.

In preparing the financial statements, management is required to evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the Company’s ability to continue as a going concern for one year after the date that the financial statements are available to be issued.

F-3

TABLE OF CONTENTS

Auditor’s Responsibilities for the Audit of the Financial Statements

Our objectives are to obtain reasonable assurance about whether the financial statements as a whole are free of material misstatement, whether due to fraud or error, and to issue an auditor’s report that includes our opinion. Reasonable assurance is a high level of assurance but is not absolute assurance and therefore is not a guarantee that an audit conducted in accordance with GAAS will always detect a material misstatement when it exists. The risk of not detecting a material misstatement resulting from fraud is higher than for one resulting from error, as fraud may involve collusion, forgery, intentional omissions, misrepresentations, or the override of internal control. Misstatements are considered material if there is a substantial likelihood that, individually or in the aggregate, they would influence the judgment made by a reasonable user based on the financial statements.

In performing an audit in accordance with GAAS, we:

•

Exercise professional judgment and maintain professional skepticism throughout the audit.

•

Identify and assess the risks of material misstatement of the financial statements, whether due to fraud or error, and design and perform audit procedures responsive to those risks. Such procedures include examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements.

•

Obtain an understanding of internal control relevant to the audit in order to design audit procedures that are appropriate in the circumstances.

•

Evaluate the appropriateness of accounting policies used and the reasonableness of significant accounting estimates made by management, as well as evaluate the overall presentation of the financial statements.

•

Conclude whether, in our judgment, there are conditions or events, considered in the aggregate, that raise substantial doubt about the Company’s ability to continue as a going concern for a reasonable period of time.

We are required to communicate with those charged with governance regarding, among other matters, the planned scope and timing of the audit, significant audit findings, and certain internal control-related matters that we identified during the audit.

Notes to Consolidated Financial Statements

Note 1. Company Description

Bremer Financial Corporation and its subsidiaries, including Bremer Bank, (collectively referred to as the “Company” or “Bremer”) is a privately held, regional financial services company jointly owned by the Otto Bremer Trust (“OBT”), Bremer directors, and Bremer employees. Founded in 1943 by Otto Bremer, the Company is headquartered in St. Paul, Minnesota and provides a comprehensive range of banking, mortgage, investment, wealth management, trust and insurance products and services primarily throughout Minnesota, North Dakota, and Wisconsin. Clients include small businesses, mid-sized corporations, agribusinesses, non-profits, public and government entities, and individuals and families. Lending and depository services are primarily provided through banking offices located in Minnesota, North Dakota, and Wisconsin.

Note 2. Accounting Policies

Basis of Presentation

The consolidated financial statements, prepared in conformity with accounting principles generally accepted in the United States, include the accounts of the Company and its subsidiaries and all variable interest entities (“VIEs”) for which the Company has both the power to direct activities of the VIE that most significantly impact the VIE’s economic performance, and the obligation to absorb losses or right to receive benefits of the VIE that could potentially be significant to the VIE. Consolidation eliminates all intercompany accounts and transactions.

Certain items in prior periods have been reclassified to conform to the current period presentation.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual experience could differ from those estimates and assumptions.

Cash, Cash Equivalents, and Due from Banks

The Company has defined cash equivalents as cash items in process, interest-bearing balances due from depository institutions with an original maturity date of less than 90 days, and federal funds sold, which have original maturity dates less than 90 days.

Investment Securities

Available-for-sale Investment Securities

Available-for-sale securities include debt securities that are carried at fair value with unrealized net gains or losses reported within other comprehensive income (loss), net of tax. These securities may be sold before maturity in response to changes in the Company’s interest rate risk profile, funding needs, demand for collateralized deposits by public entities, or other reasons. Realized gains or losses on securities are determined on a trade date basis based on the specific amortized cost of the investments sold. Declines in fair value related to credit, if any, are recorded by establishing an allowance for credit losses.

Securities in an unrealized loss position are assessed to determine whether management intends to sell, or it is more likely than not they will be required to sell the security before recovery of its amortized cost basis. If either criterion is met, the security’s amortized cost is written down to fair value through income.

For securities that do not meet either criterion, management periodically evaluates whether the decline in fair value below the amortized cost basis of the security is the result of credit related factors. As a part of this evaluation, management considers various factors such as the extent of the unrealized loss, nature of

F-10

TABLE OF CONTENTS

the investment security, credit ratings or financial condition of the issuer, expected cash flow scenarios, existence of any government or agency guarantees, and market conditions. If there is indication that a credit loss exists, the Company measures the allowance for credit losses using market information where available and discounting expected cash flows at the original effective rate of the investment security. The present value of expected cash flows is compared to the security’s amortized cost with any excess amortized cost recorded as a credit loss. The credit loss is limited to the excess of the security’s amortized cost over fair value. Changes in the allowance for credit losses are reported within provision for credit losses on the consolidated income statement. Charge-offs are recognized against the allowance when uncollectibility on the security is confirmed or the criteria regarding intent or requirement to sell is met. Refer to Note 5 for additional information.

Accrued interest receivable is excluded from the amortized cost basis of available-for-sale securities and the measurement of the allowance for credit losses. Accrued interest receivable on available-for-sale securities is presented within other assets in the consolidated balance sheet.

Held-to-maturity Investment Securities

Debt securities for which the Company has the positive intent and ability to hold to maturity are reported at historical cost adjusted for amortization of premiums and accretion of discounts. Expected credit losses, if any, are recorded by establishing an allowance for credit losses.

The held-to-maturity investment securities are comprised of U.S. Treasury and U.S. agency mortgage-backed securities that are issued by U.S. government entities or agencies, are either explicitly or implicitly guaranteed by the U.S. government, and have no history of credit losses. Accordingly, the Company does not expect to incur any credit losses on held-to-maturity investment securities and no allowance for credit losses has been recorded at December 31, 2023.

Accrued interest receivable is excluded from the amortized cost basis of held-to-maturity securities and the measurement of the allowance for credit losses. Accrued interest receivable on held-to-maturity securities is presented within other assets in the consolidated balance sheet.

Loans Held for Sale

Loans held for sale (“LHFS”) represent loans originated by the Company, intended to be sold in the secondary market. LHFS primarily include first lien, single-family residential mortgage loans that conform to underwriting standards of the Government Sponsored Enterprises (“GSEs”). The LHFS portfolio is carried at the lower of cost or fair value, with any changes in carrying value recorded in noninterest income. Net gains realized on the sales of loans are recognized in noninterest income at the time of sale and are determined by the difference between the net sales proceeds and the carrying value of the loans sold, including any deferred origination fees and costs.

Loans Held for Investment

Loans held for investment (“LHFI”) include loans originated by the Company, as well as purchased loans, that management has the intent and ability to hold for the foreseeable future or until maturity or payoff. The Company’s accounting methods differ depending on whether the loans are originated or purchased, and for purchased loans, whether the loans contained evidence of credit deterioration at acquisition.

Originated LHFI

Originated LHFI are reported at the principal amount outstanding adjusted for charge-offs, the allowance for credit losses, and net of unearned income or deferred loan fees and costs. Interest income is accrued based on the principal amount outstanding. Certain direct loan origination fees and costs, as well as commitment fees, are deferred and recognized over the life of the loan or commitment as yield adjustments. The Company has elected to exclude accrued interest receivable from the amortized cost basis of LHFI and the measurement of the allowance for credit losses. Accrued interest receivable related to LHFI is presented within other assets in the consolidated balance sheet.

F-11

TABLE OF CONTENTS

Purchased LHFI

All purchased LHFI are measured at their initial investment or at fair value if acquired as a part of a business combination, in accordance with applicable accounting guidance. For loans acquired after December 31, 2022, an allowance for credit losses is determined using the same methodology as other loans held for investment. The initial allowance for loans considered purchase credit deteriorated (PCD) is established by adjusting the basis of the acquired loans whereas the allowance for non-PCD loans is recognized through provision expense. Non-credit related premiums and discounts are amortized and accreted into income over the life of the loan. The Company did not have any PCD loans at December 31, 2023.

Prior to January 1, 2023, purchased LHFI were measured at their initial investment or at fair value if acquired as a part of a business combination, including any credit discounts, in accordance with applicable accounting guidance. An allowance for loan losses was not recorded at the acquisition date.

Allowance for Credit Losses

Beginning January 1, 2023, the allowance for credit losses is established for current expected credit losses on the Company’s loan portfolio, including unfunded commitments. The allowance considers expected losses for the remaining contractual lives of the applicable assets, inclusive of expected recoveries and prepayments. The allowance is increased through provisions charged to earnings and reduced by net charge-offs. Management evaluates the allowance for credit losses on a quarterly basis.

The Company considers multiple economic scenarios over a reasonable and supportable two-year forecast period. Expected credit losses for periods beyond the reasonable and supportable forecast period are determined based on a reversion method which reverts to long-term historical loss estimates over a consecutive four quarter period on a straight-line basis. Economic scenarios are weighted based on the Company’s expectation of economic conditions for the foreseeable future and reflect significant judgment and consideration of forecast uncertainty. Other factors affecting credit losses not reflected in the economic scenarios may be considered by management when estimating expected credit losses. These factors may include, but are not limited to, loan servicing practices, regulatory guidance, and/or fiscal or monetary policy actions.

The allowance for credit losses utilizes forward-looking expected loss models to consider a variety of factors affecting lifetime credit losses. These factors include, but are not limited to, macroeconomic variables such as unemployment rates, unemployment claims, nonfarm employment levels, real gross domestic product levels, home price index, commercial real estate price index, and agriculture price index, as well as loan and borrower characteristics, such as probability of default, loss given default, and exposure at default depending on the loan risk characteristics, delinquency status, industry, geographic location, collateral type and available valuation information, and the remaining term of the loan, adjusted for expected prepayments.

The Company offers a broad array of lending products and categorizes its loan portfolio into two segments, which is the level at which it develops and documents a systematic methodology to determine the allowance for credit losses. The Company’s two loan portfolio segments are commercial lending and consumer lending. The Company further disaggregates its loan portfolio segments into various classes based on their underlying risk characteristics. The three classes within the commercial lending segment are commercial loans, commercial real estate loans, and agriculture loans. The two classes within the consumer lending segment are residential mortgages and retail loans. Where similar loan risk characteristics exist, the allowance is measured on a collective (pool) basis.

The commercial class consists of loans made to businesses to provide financing for business operations, capital purchases, acquisitions, expansions, and other business investments. Lending in this segment is to a wide variety of industries, including manufacturing, retail operations, education, health care, professional offices, nonprofits, and municipalities. These loans are generally secured by business assets and guaranteed by owners, and cash flows from operations are generally the primary source of repayment. Key risk characteristics relevant to this class include the industry, geography, size of the borrower’s business, repayment sources, the borrower’s debt capacity and financial performance, strength and liquidity of guarantors,

F-12

TABLE OF CONTENTS

management expertise, loan covenants, and value of collateral. The Company considers these characteristics in assigning risk ratings and estimating the allowance.

The commercial real estate class includes loans made to businesses secured by real estate. Properties securing the loans in this class are comprised of both owner-occupied and non-owner-occupied properties. Non-owner-occupied properties include hotels and lodging, multifamily residential buildings, office buildings, office warehouses, medical/assisted living, and retail buildings. Key risk characteristics relevant to this class include the industry, geography, size of the borrower’s business, repayment sources, borrower’s debt capacity and financial performance, strength and liquidity of guarantors, loan covenants, tenants, property characteristics, and value of collateral. The Company considers these characteristics in assigning risk ratings and estimating the allowance.

The agriculture class includes loans made to individuals and businesses involved in agriculture, including crop and livestock production, dairy, and other agribusiness activities. Loans in this segment are generally secured by agricultural land, crops, livestock, equipment, and operating assets and are guaranteed by owners. The primary source of repayment is generally cash flow from operations. Key risk characteristics relevant to this class include the geography of the borrower’s operations, industry characteristics, commodity prices, marketing activity, weather patterns, insurance and government program support, repayment sources, borrower’s debt capacity and financial performance, loan covenants, and value of collateral. The Company considers these characteristics in assigning risk ratings and estimating the allowance.

The residential real estate class includes loans made to consumers, including residential first mortgages, residential construction loans, and home equity first lien loans. These loans are typically fixed-rate loans secured by residential real estate. Key risk characteristics relevant to this class include the borrower’s capacity and willingness to repay, payment history, income and debt levels, value and location of collateral, unemployment rates, and other economic factors. The Company considers these characteristics in assigning, as applicable, risk classifications and estimating the allowance.

The retail class includes consumer loans, including home equity second lien loans, loans secured by automobiles and other installment loans, and unsecured term loans and revolving credit lines. Key risk characteristics relevant to this segment include the borrower’s capacity and willingness to repay, payment history, income and debt levels, value and location of collateral, unemployment rates, and other economic factors. The Company considers these characteristics in assigning, as applicable, risk classifications and estimating the allowance.

Loans that do not exhibit similar risk characteristics are evaluated on an individual basis and are not included in the collective evaluation. If an individually evaluated loan is determined to be collateral dependent or meets the criteria to apply the collateral dependent practical expedient, expected credit losses are estimated based on the fair value of collateral less applicable selling costs. If not, a discounted cash flows methodology is used.

The Company’s methodology for determining the allowance for credit losses also considers the need for adjustments to the estimated allowance amounts described above as a result of limitations inherent in the methodologies used. Using a systematic approach, necessary adjustments are made to consider the potential impact of other qualitative factors not captured in the quantitative model which include, but are not limited to, the following: model imprecision, imprecision in economic scenario assumptions, and emerging risks related to changes in the economic environment that are affecting specific loan segments. The consideration of these qualitative factors is incorporated in the allowance for credit losses for each loan class.

Prior to implementation of Accounting Standard Update 2016-13 on January 1, 2023, the Company was required to use an incurred loss methodology to estimate credit losses. The allowance for credit losses and resulting provision expense levels for comparative periods presented were estimated in accordance with that methodology and applicable accounting guidance.

Allowance for Unfunded Commitments

The allowance for unfunded commitments is determined using similar procedures and methodologies used for LHFI supplemented by the information related to future funding expectations. The future funding

F-13

TABLE OF CONTENTS

expectations are based on historical weighted average utilization levels. The reserve is included in accrued expenses and other liabilities on the consolidated balance sheet. Net adjustments to the reserve for unfunded commitments are included in provision for credit losses on the consolidated statement of income.

Nonaccrual and Past Due Loans

The LHFI portfolio is reviewed regularly by the Company and loans are placed on nonaccrual status when the collection of interest or principal is unlikely. When a loan is placed on nonaccrual status, unpaid accrued interest is reversed and future interest accruals are suspended. The Company’s policy is to assign loans to nonaccrual status when payment of interest and principal in full is not expected, principal or interest has been in default for 90 days, the loan is being maintained on a cash basis due to the deterioration in the condition of the borrower, or the loan has otherwise been determined to be impaired. An exception to this policy can be made if a loan is well-collateralized and in the process of collection, with the expectation that the loan will be fully repaid or brought current before it becomes a maximum of 150 days past due.

A nonaccrual loan may be restored to accrual status when 1) none of its principal and interest is due and unpaid and the Company expects repayment of the remaining contractual principal and interest as agreed; 2) the borrower has resumed paying the full amount of the scheduled contractual interest and principal payments for a minimum of six months; or 3) repayment criteria established by the Company to bring the loan current have been met, even though the loan has not yet been brought fully current.

Credit Quality and Risk Ratings

The Company categorizes its loans into one of 12 internal risk rating categories that are based on relevant information about the borrower’s ability to service debt, as well as expectations for future performance, with primary consideration in assigning risk ratings being the strength of the primary repayment source for the loan. The Company categorizes its loans into the internal risk rating categories on an ongoing basis.

The 12 internal risk rating categories are mapped to pass, special mention, or classified credit quality indicator categories. Pass loans are not classified on the Company’s rating scale for problem credits, as minimal credit risk has been identified. Special mention loans have a potential weakness requiring credit monitoring activities. Classified loans have a well-defined weakness that results in greater risk regarding the full collection of contractual cash flows. Loans in the special mention and classified categories are considered criticized loans.

Impaired Loans

A loan is considered impaired when management determines it is probable that the Company will be unable to collect all amounts due according to the original contractual terms of the loan agreement. Impairment is measured as the difference between the recorded investment in the loan (including accrued interest, net deferred loan fees or costs, and unamortized premium or discount) and the estimated present value of total expected future cash flows, discounted at the loan’s effective rate, or the fair value of the collateral less selling costs, if the loan is collateral dependent. Impairment is recognized by either adjusting the allowance for credit losses, or by charging off the impaired amount. All nonaccrual loans meet the definition of impaired loans.

Loan Modifications

In certain circumstances, the Company may modify the terms of a loan to maximize the collection of amounts due when a borrower is experiencing financial difficulties or is expected to experience financial difficulties in the near- term. In most cases, the modification is either a concessionary reduction in interest rate, extension of the maturity date, or reduction in the principal balance that would otherwise not be considered. If a loan has been formally restructured and, under the restructured agreement, the payments have been current for six months and all future payments are expected to be collected in full and in a timely manner, the loan may be returned to accruing status.

F-14

TABLE OF CONTENTS

Charge-Offs

Commercial, commercial real estate, and agricultural loans are charged-off when they are determined to be impaired and uncollectible and the net realizable value of the underlying collateral or expected cash flows is less than the Company’s recorded investment in the loan.

Residential real estate loans are placed on nonaccrual status during the month the loan becomes 90 consecutive days past due. A current value of the real estate collateral is determined before the loan is 180 consecutive days past due, and any loan balance in excess of the collateral value, less selling costs, is charged off. Collateral values are periodically updated when necessary.

Other secured consumer loans not secured by real estate will be charged off during the month when the loan becomes 120 days past due. The entire loan balance is charged off unless a substantiated value can be assigned to the collateral, in which case the loan is charged down to the value of the collateral less selling costs.

Unsecured consumer loans are charged off during the month when the loan becomes 90 days past due.

Other Real Estate Owned

Other real estate owned (“OREO”) represents properties that have been acquired in satisfaction of debt through foreclosure, or real estate holdings as otherwise defined by bank regulators, and is initially recorded at fair value less estimated costs to sell. Any adjustment to fair value less costs to sell at the time of foreclosure is charged to the allowance for loan losses. The properties are appraised periodically to ensure that the recorded amount is supported by the current fair value, less costs to sell. OREO is included in other assets on the consolidated balance sheets. Adjustments to fair value, less costs to sell and subsequent to the initial adjustment, based on declines in property value, operating expenses, and losses on sales, are charged to noninterest expense, while income, including gains on sales, is included in other noninterest income.

Premises and Equipment

Premises and equipment are carried at cost, less accumulated depreciation, with depreciation generally calculated on a straight-line basis over the estimated useful lives of the assets, which range from 3 to 39 years. Maintenance and repair costs are charged to net occupancy and equipment expense on the consolidated statement of income as incurred. Gains and losses on disposition of premises and equipment are included in other noninterest income and other noninterest expense on the consolidated statement of income.

The Company, as lessee, records a right of use asset (ROU) for each lease with an original term greater than 12 months. ROU assets are included in premises and equipment, with the corresponding lease liabilities included in accrued expenses and other liabilities on the consolidated balance sheet.

Capitalized Software

The Company capitalizes certain costs associated with the acquisition or development of internal-use software. Once the software is ready for its intended use, these costs are amortized on a straight-line basis over the software’s expected useful life and reviewed for impairment on an ongoing basis. The estimated useful life is generally 3 years. Capitalized software costs are recorded within other assets on the consolidated balance sheet. Capitalized software amortization expense, impairment charges, and contract termination costs are included in other noninterest expense on the consolidated income statement.

Goodwill and Other Intangible Assets

Intangible assets include goodwill, mortgage servicing rights (“MSRs”), core deposit premiums, and other intangible assets. Goodwill represents the excess of acquisition cost over the estimated fair value of assets acquired and liabilities assumed in a business combination. Other intangibles primarily relate to the value associated with certain purchased portfolios or business activities, whether through a business combination or other purchase. Goodwill is not amortized, and the Company assesses goodwill for impairment annually as of October 1. The Company evaluates certain qualitative considerations, supplemented by quantitative metrics, as part of the evaluation. Other intangible assets and core deposit

F-15

TABLE OF CONTENTS

premiums with finite lives are amortized over a period of time and are evaluated for impairment if certain indicators of impairment are identified.

MSRs are capitalized as separate assets when mortgage loans are sold to third parties and the contractual right to service the loans is retained. The Company has elected to account for the MSRs at fair value. Because MSRs do not trade in an active market with readily observable prices, the Company determines the fair value by estimating the present value of future cash flows associated with the contractual servicing activities, using a discounted cash flow calculation and market based assumptions, such as prepayment rates, discount rates, and other assumptions. The estimate of MSR fair value is calculated by a third-party valuation firm and significant assumptions are benchmarked against peers. Changes in the fair value of MSRs are included in noninterest income on the consolidated statement of income.

Bank Owned Life Insurance

The Company has purchased single-premium bank-owned life insurance (“BOLI”), insuring a group of its key officers. Substantially all BOLI is in the form of an experience-rated mortality, separate-account product. BOLI is included on the consolidated balance sheet at its cash surrender value (“CSV”). Earnings on the underlying investments, less mortality and servicing costs, increase the CSV of the policy on the consolidated balance sheet and are included in other noninterest income on the consolidated statement of income.

Derivatives and Hedging Activities

The Company is exposed to certain risks arising from both its business operations and economic conditions. The Company principally manages its exposures to business and operational risks through management of its core business activities. The Company manages economic risks, including interest rate, liquidity, and credit risk, primarily by managing the amount, sources, and duration of its debt funding and the use of derivative financial instruments. Specifically, the Company enters into derivative financial instruments to manage exposures that arise from business activities that result in the receipt or payment of future known and uncertain cash amounts, the value of which are determined by interest rates. The Company’s derivative financial instruments are used to manage differences in the amount, timing, and duration of the Company’s known or expected cash receipts and its known or expected cash payments principally related to certain floating and fixed-rate borrowings. The Company records all derivatives on the balance sheet at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivatives, whether the Company has elected to designate the derivatives in a hedging relationship and apply hedge accounting, and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting.

Derivatives designated and qualifying as hedges of the exposure to changes in the fair value of an asset, liability, or firm commitment attributable to a particular risk, such as interest rate risk, are considered fair value hedges.

Derivatives designated and qualifying as hedges of the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. Hedge accounting generally provides for the matching of the timing of gain or loss recognition on the hedging instrument with the recognition of the changes in the fair value of the hedged asset or liability that are attributable to the hedged risk in a fair value hedge or the earnings effect of the hedged forecasted transactions in a cash flow hedge. For derivatives designated as fair value hedges, changes in fair value of the derivatives and corresponding assets or liabilities are included in interest income or expense on the consolidated statement of income. For derivatives designated as cash flow hedges, changes in the fair value of the derivatives are included in other comprehensive income, net of tax.

The Company may enter into derivative contracts that are intended to economically hedge certain risks even though the Company elects not to apply hedge accounting. Also, certain derivatives not designated as hedges result from a service the Company provides to certain qualified commercial banking customers by executing interest rate derivatives with these customers to facilitate their risk management strategies. Those derivatives are simultaneously hedged by offsetting derivatives that the Company executes with a

third party, such that the Company minimizes its net risk exposure resulting from such transactions. Changes in fair value are included in noninterest income on the consolidated statement of income.

As part of the Company’s risk management strategy in the residential mortgage banking business, derivative instruments such as forward sales contracts are utilized. The Company’s obligations under forward contracts consist of commitments to deliver mortgage loans originated at a future date. The Company also has derivative contracts that are created through its mortgage operations when the Company commits to originate a mortgage loan intended to be sold at a future date, referred to as interest rate lock commitments. The fair value of forward sales contracts and interest rate lock commitments are included in other assets or accrued expenses and other liabilities on the consolidated balance sheet. Changes in fair value of these instruments are included in other noninterest income on the consolidated statement of income.

Employee Benefit Plans

The Company provides a defined benefit pension plan to substantially all employees based on years of service and employee compensation while employed with the Company. Depending on the measurement of the liability and the fair value of plan assets, a net asset or liability may be recorded. Liabilities related to future benefit obligations and assets related to the Company’s funding contributions are measured using assumptions, including long-term discount rates and the expected return on plan assets. The Company recognizes the net funded or unfunded status of the defined benefit pension plan in other assets or accrued expenses and other liabilities on the consolidated balance sheet. Deferred actuarial gains and losses, and the prior service costs and credits, are recorded in other comprehensive income, net of tax. Periodic service-related costs associated with this plan are recorded in compensation and employee benefit expense on the consolidated statement of income. Other net benefit costs are recorded within other noninterest expense on the consolidated statement of income.

Income Taxes

The Company is subject to U.S. federal income tax, as well as income tax in certain state jurisdictions. Income tax expense consists of two components, current and deferred. Current income tax expense reflects taxes to be paid or refunded for the current period. Deferred income tax expense relates to timing differences between the period in which transactions are reflected on the consolidated financial statements (referred to as the “book basis”) and the period in which transactions are considered taxable (referred to as the “tax basis”). The Company determines deferred income taxes using the balance sheet method. Under this method, the net deferred tax asset or liability is based on the tax effects of the differences between the book and tax bases of assets and liabilities and enacted changes in tax rates and laws are recognized in the period in which they occur. Deferred income tax expense results from changes in deferred tax assets and liabilities between periods. Deferred tax assets are recognized subject to management judgment that realization is more likely than not. The Company recognizes interest and penalties related to unrecognized tax benefits in income tax expense on the consolidated statement of income.

Changes in relevant tax laws may impact the measurement of deferred tax assets and liabilities. The impact of changes to tax law, including changes to tax rates, on the measurement of deferred taxes is included in current income tax expense on the consolidated statement of income at the date of enactment.

Revenue Recognition

In the ordinary course of business, the Company recognizes income derived from various revenue generating activities. Certain revenues are generated for amounts the Company expects to be entitled to from contracts with customers related to the transfer of services or products. Total revenue from certain contracts with customers, which is accounted for under applicable revenue recognition accounting guidance, of $81.3 million and $81.5 million was recognized for the years ended December 31, 2023 and 2022, respectively. Revenue generating activities related to financial assets and liabilities are also recognized but accounted for under other applicable accounting guidance; including interest income on loans and investment securities, mortgage servicing fees and other mortgage banking activities, loan commitment fees, gains and losses on securities, fees collected related to customer derivatives activities, and other miscellaneous income items. Certain specific policies include the following:

F-17

TABLE OF CONTENTS

Credit and Debit Card Revenue

Debit card revenue includes interchange from debit cards processed through card association networks and other transaction and account management fees. Interchange rates are generally set by the card associations and based on purchase volumes and other factors. The Company records interchange as services are provided. Other fees, including transaction fees, are recognized as services are provided. Credit card revenue includes fees earned related to joint marketing agreements with unrelated third parties and is recorded when services are provided. Credit and debit card revenue is recorded within service charges on the consolidated statement of income.

Deposit Service Charges

Deposit service charges include service charges on deposit accounts received under depository agreements with customers to provide access to deposited funds and serve as a custodian of funds. Checking or savings accounts may contain fees for various services used on a day-to-day basis by a customer. Fees are recognized as services are delivered to and consumed by the customer, or as penalty fees are charged. Deposit service charges are recorded within service charges on the consolidated statement of income.

Insurance Revenue

Insurance revenue includes commissions related to policies provided to customers through agency contracts with insurance carriers. Coverage types primarily relate to property and casualty policies. Commission revenue is generally recorded on the effective date of the policy or when control of the policy has transferred to the applicable carrier. These commissions are recorded within insurance revenue on the consolidated statement of income.

Investment Management and Trust Fees

Investment management and trust fees are recognized over the period in which services are performed and are generally based on a percentage of the fair value of the assets under management or administration, as well as other asset management related fees. Revenue related to these activities is recorded within investment management and trust fees on the consolidated statement of income.

Brokerage Revenue

Brokerage revenue includes commissions related to the execution of requested security trades and investment advisory fees. Commissions and investment advisory fees are recognized as services are delivered to and utilized by the customer. These fees are recorded within brokerage revenue on the consolidated statement of income.

Comprehensive Income

Comprehensive income is defined as the change in equity during a period resulting from transactions and other events and circumstances from non-owner sources. For the Company, comprehensive income consists of net income, as reported on the consolidated statement of income, and other comprehensive income, net of tax, which includes the change in unrealized gains and losses on available-for-sale securities, derivatives and hedging activities, and pension and other postretirement plans related gains and losses and prior service cost or credits that arise during the period but are not recognized as components of net periodic benefit cost. Income tax effects of amounts reported within other comprehensive income (loss) related to available-for-sale securities are released under the portfolio approach. Income tax effects of amounts recorded within other comprehensive income (loss) related to employee benefit plans would be released upon termination of the plans.

Note 3. Recent Accounting Pronouncements

The following summarizes recent accounting standards updates (“ASU”) issued by the FASB, which are relevant to the Company and were adopted during the years ended December 31, 2023 or December 31, 2022, or that will be applicable in a future period:

ASU 2023-09 — Income Taxes (Topic 740): Improvements to Income Tax Disclosures	In December of 2023, the FASB issued new accounting guidance related to income tax disclosures. The amendments in this update require additional income tax rate reconciliation and income taxes paid disclosures. The guidance may be adopted on a prospective or retrospective basis.	The guidance is effective fiscal years beginning after December 15, 2024 with early adoption permitted. The Company is evaluating the impact of the guidance on its consolidated financial statements.
ASU 2023-02 — Investments — Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method	In March of 2023, the FASB issued new accounting guidance related to accounting for tax credit investments. Under the new guidance, an entity may elect, on a program-by-program basis, to account for tax credit investments using the proportional amortization method if certain conditions are met. The guidance may be adopted on a modified retrospective or retrospective basis.	The guidance is effective fiscal years beginning after December 15, 2023, including interim periods within those fiscal years. The Company is evaluating the impact of the guidance on its consolidated financial statements.
ASU 2022-02 — Financial Instruments — Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures	In March of 2022, the FASB issued new accounting guidance related to troubled debt restructurings (TDR) and vintage disclosures. The guidance eliminates TDR accounting while enhancing disclosure requirements for certain loan modifications made to borrowers experiencing financial difficulty. It also requires disclosure of current period gross charge-offs by year of origination for financing receivables.	The Company adopted the guidance as of January 1, 2023 on a modified retrospective basis. The adoption of this guidance is not material to the Company’s consolidated financial statements.
ASU 2022-01 — Derivatives and Hedging (Topic 815): Fair Value Heding — Portfolio Layer	In March of 2022, the FASB issued new accounting guidance related to fair value hedge accounting of portfolios of financial assets. Under the new guidance, the current last-of-layer method is expanded to allow for multiple hedge layers in a single closed portfolio and, as a result, was renamed the portfolio layer method. It also expands the scope of this method to non- prepayable financial assets.	The Company adopted the guidance as of January 1, 2023 on a prospective basis. The adoption of this guidance is not material to the Company’s consolidated financial statements.

ASU 2020-04 — Facilitation of the Effects of Reference Rate Reform on Financial Reporting ASU 2022-06 — Deferral of the Sunset Date of Topic 848	In March 2020, the FASB issued new accounting guidance to provide optional expedients and exceptions for applying US GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The amendments apply only to contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. The following expedients are provided for modified contracts whose reference rate is changed: 1) receivables and debt contracts are accounted for prospectively by adjusting the effective interest rate, 2) leases are accounted for as a continuation of the existing contracts with no reassessments of the lease classification and discount rate or remeasurements of lease payments that otherwise would be required, and 3) an entity is not required to reassess its original conclusion about whether that contract contains an embedded derivative that is clearly and closely related to the economic characteristics and risks of the host contract. When elected the expedients must be applied consistently for all eligible contracts or transactions. In December 2022, the FASB issued guidance to defer the sunset date of ASU 2020-04 from December 31, 2022 to December 31, 2024 and to make the optional expedients available through the LIBOR transition date of June 30, 2023.	The guidance is subject to election as of March 12, 2020 and can be elected through December 31, 2024. The Company has made certain elections under the guidance. The elections made did not have a material impact on the consolidated financial statements

			incurred loss model that is currently in use. Under the new guidance, an entity will measure all expected credit losses for financial instruments held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. The expected loss model will apply to loans and leases, unfunded lending commitments, held-to- maturity debt securities and other debt instruments measured at amortized cost. The impairment model for available-for-sale debt securities will require the recognition of credit losses through a valuation allowance when fair value is less than amortized cost and the decline is due to credit-related factors, regardless of whether the impairment is considered to be other-than-temporary. The guidance was effective on January 1, 2023, with a cumulative-effect adjustment to retained earnings as of that date.			adoption of CECL resulted in a decrease in the Company’s allowance for credit losses and the liability for expected credit losses on commitments to extend credit as a result of changing from the “incurred loss” model, which encompassed allowances for current known and inherent losses within the portfolio, to the “expected loss” model, which encompasses allowances for losses expected to be incurred over the contractual life of the portfolio. The adoption impacts were applied through a cumulative-effect adjustment to retained earnings of $16.9 million as of January 1, 2023. The transition adjustment included a decrease in the allowance for credit losses of $23.2 million net of the corresponding decrease in deferred tax assets of $6.3 million. The adoption of CECL did not have a material impact on the Company’s investment securities portfolio.

Note 4. Restrictions on Cash, Cash Equivalents, and Due from Banks

Banking regulators may require bank subsidiaries to maintain minimum average reserve balances, either in the form of vault cash or reserve balances held with central banks or other financial institutions. The Company did not have reserve requirements at December 31, 2023 and 2022, respectively.

Proceeds from sales and calls of available-for-sale investment securities were $76.6 million and $25.8 million for the years ended December 31, 2023 and 2022, respectively. Net gains of $0.5 million and $0.1 million were realized on those sales and calls for the years ended December 31, 2023 and 2022, respectively. For 2023, the net losses include $3.1 million of non-credit related impairments recognized as a result of management’s intention to sell certain available-for-securities.

These unrealized losses primarily relate to changes in interest rates and market spreads subsequent to purchase of these available-for-sale investment securities. U.S. Treasury, obligations of U.S. government agencies, and agency mortgage-backed securities are issued, guaranteed, and otherwise supported by the United States government. The Company’s obligations of state and political subdivisions, non-agency residential mortgage-backed securities, and corporate debt securities are generally high grade. Accordingly, the Company does not consider these unrealized losses to be credit related and an allowance for credit losses is not necessary.

For the years ended December 31, 2023 and 2022, the Company recognized non-credit related impairment losses of $3.1 million and $0.0 million, respectively, on available-for-sale securities. The recognition of the $3.1 million related to management’s intention to sell certain available-for-sale securities in a non-credit related unrealized loss position at time of the decision. At December 31, 2023, the Company had no other plans to sell investment securities with unrealized losses, and believes it is more likely than not it would not be required to sell such investment securities before recovery of the respective amortized cost.

Loan Modifications

Note 7. Mortgage Banking

Residential Mortgage Loan Sales

The Company completes residential mortgage loan sales in the normal course of business, primarily to GSEs, resulting in the derecognition of sold loan amounts from the consolidated balance sheet. In accordance with the accounting guidance for the transfer of financial assets, the Company considers any continuing involvement with residential mortgage loans sold in determining whether such assets can be derecognized from the consolidated balance sheet. The Company’s continuing involvement with residential mortgage loans sold is generally limited to customary market servicing arrangements and representation and warranty clauses. MSR assets are recorded at the fair value of the servicing arrangements. Liabilities related to representation and warranty clauses are initially recorded at fair value and were not material at December 31, 2023 or 2022. Any gain or loss on sale of residential mortgage loans depends on the previous carrying amount, the consideration received, and any liabilities incurred in exchange for the sold loans. Upon sale, any servicing assets or other interests that continue to be held by the Company are initially recognized at fair value.

Proceeds from residential mortgage loans sold were $182.4 million and $319.1 million during the years ended December 31, 2023 and 2022, respectively. Net gains on sales of residential mortgage loans included in mortgage banking and loan fee income, including origination fees, the initial fair value of originated MSRs, and servicing release premiums received, were $6.0 million and $6.7 million for the years ended December 31, 2023 and 2022, respectively.

Risk Management

In the normal course of business, the Company issues interest rate lock commitments to customers. To the extent such commitments relate to loans the Company intends to sell to a third party, the commitment is initially recognized at fair value at the date of the commitment. The Company records closed mortgage loans held for sale at the lower of cost or fair value.

F-29

TABLE OF CONTENTS

Through these mortgage banking activities, the Company assumes interest rate risk through interest rate lock commitments, as well as mortgage loans held for sale. As part of the Company’s risk management strategy, the Company makes offsetting commitments for future delivery of residential mortgage-backed securities. The primary objective of economically hedging mortgage banking activities is to offset changes in the fair value of interest rate lock commitments and mortgage loans held for sale. Activity included in mortgage banking and loan fees was $0.8 million in gains and $3.9 million in gains for the years ended December 31, 2023 and 2022, respectively. Refer to Note 18 for additional information regarding this economic hedging activity and Note 21 for information regarding the fair value of interest rate lock commitments and mortgage loans held for sale.

Mortgage Servicing Rights

The Company serviced $2.1 billion of residential mortgage loans for others at December 31, 2023 and 2022. Loan servicing fees included in mortgage banking and loan fees were $5.2 million and $5.4 million for the years ended December 31, 2023 and 2022, respectively.

The fair value of MSRs is recorded within goodwill and other intangibles, net on the consolidated balance sheet. Changes in the fair value of MSRs, which are included in mortgage banking and loan fees on the consolidated income statement, are summarized as follows:

Year Ended December 31 (Dollars in Thousands)	2023			2022
Balance at beginning of period		$	25,331		$	19,458
Origination of servicing assets			1,318			3,081
Change in fair value of MSRs
Due to market changes			(1,270)			5,635
Due to loan portfolio runoff			(2,069)			(2,843)
Balance at end of period		$	23,310		$	25,331

The following table provides the aggregate unpaid principal balance of mortgage loans serviced for others, as well as the third parties for which loans are serviced, at December 31:

(Dollars in Thousands)	2023			2022
Federal National Mortgage Association		$	1,704,661		$	1,737,312

Federal Home Loan Bank and other			409			452
		$	2,081,283		$	2,122,243

In the determination of the fair value of MSRs, certain key assumptions are made. The key assumptions considered by the Company were the constant prepayment rate (“CPR”), which is an estimated loan prepayment rate that uses historical prepayment rates for previous loans similar to the loans being evaluated, and a market based discount rate. Refer to Note 21 for additional information regarding the fair value of MSRs.

The following table provides information about the fair value of MSRs and the related key assumptions at December 31:

Less: accumulated depreciation and amortization			118,225			128,058
Premises and equipment, net		$	140,969		$	129,349

Depreciation and amortization expense on premises and equipment was $10.5 million and $11.4 million for the years ended December 31, 2023 and 2022, respectively. Depreciation on premises and equipment is calculated on a straight-line basis for book purposes. Buildings are depreciated over an estimated useful life not to exceed 39 years, furniture and equipment is depreciated over periods of between 3 and 10 years, and leasehold improvements are depreciated over the term of the underlying lease, not to exceed the estimated useful life of the improvements.

The Company leases certain facilities for use in its operations, which each are accounted for as operating leases. Leased facilities include retail branches and other corporate offices and locations. For each lease, the Company records a lease liability and a corresponding right of use (ROU) asset. The Company had recorded $17.5 million and $19.5 million of ROU assets within premises and equipment, net and $19.3 million and $20.2 million of lease liabilities within accrued expenses and other liabilities on the consolidated balance sheet at December 31, 2023 and 2022 respectively. Total expenses incurred related to these lease agreements during the year ended December 31, 2023 and 2022, was $5.2 million and $5.4 million respectively, which was primarily attributable to contractual lease payments.

At December 31, 2023, the weighted average remaining term and discount rate of the Company’s leased assets were 11.5 years and 3.4%, respectively. At December 31, 2022, the weighted average remaining term and discount rate of the Company’s leased assets were 12.3 years and 3.2%, respectively.

Contractual future minimum rental payments for operating leases in excess of one year in subsequent fiscal years are as follows:

2029 and thereafter		12,389

Note 9. Intangible Assets

Intangible assets consist of goodwill, core deposit premiums, MSRs, and other intangibles. Goodwill and MSRs are not amortized. Goodwill is assessed for impairment on an annual basis, and MSRs are recorded at fair value. No impairment of goodwill was recorded for the years ending December 31, 2023 and 2022. Refer to Note 7 for additional information regarding MSRs.

Amortization of core deposit premiums and other intangibles is included in noninterest expense on the consolidated statement of income, with amortization periods of 7 to 15 years.

Includes amounts related to derivatives and hedging activities for subordinated notes. Refer to Note 18 for additional information.

In June 2006, the Company issued $61.9 million in junior subordinated deferrable interest debentures (“debentures”) in connection with the issuance of $60.0 million of capital securities through Bremer Statutory Trust II (“BSTII”). The Company evaluated BSTII and concluded that the trust is a variable interest entity not subject to consolidation. The debentures bear interest at a floating rate of three-month CME Term SOFR, plus 1.86%, resulting in a rate of 7.24% at December 31, 2023. The debentures mature on June 1, 2036 but may be redeemed by the Company at par on any quarterly interest payment date at the Company’s discretion. At December 31, 2023, the $60.0 million in capital securities qualified as Tier I capital under guidelines of the FRB.

In December 2014, the Company issued $100.0 million in subordinated notes to support ongoing business operations and the Company’s future growth strategy. The notes bear interest at a 5.20% fixed rate

and mature on December 30, 2024. At December 31, 2023, none of the subordinated debt qualified as Tier II capital under guidelines of the FRB. The Company phased out the subordinated notes from Tier II capital over a 5 year period, beginning in December 2019. In January 2015, the Company entered into a 10-year, pay variable, receive fixed, interest rate swap to hedge the subordinated debt. The company terminated the swap in July 2021. For additional detail, see the “Fair Value Hedges of Interest Rate Risk” section under Note 18.

The FHLB borrowings bear interest at rates ranging from 4.13% to 5.57%, with maturity dates from 2024 through 2028, and are secured by certain loans as discussed in Note 6.

The Company enters into certain tax credit investment structures related to the New Markets Tax Credits program (“NMTCs”). As a result, the Company records certain notes payable, which are issued in the normal course of business as part of NMTC investment structures. The purpose of these notes is to supplement the investments made by the Company by financing projects that generate tax credits. Each of the notes is structured with a seven year interest only period, and maturity dates ranging from 2027 through 2053. Each structure contains separate put agreements, which allow the Company to put the notes to designated third parties at the end of the seven year interest only period. The notes bear a weighted average interest rate of 3.45%.

Maturities of outstanding long-term debt at December 31, 2023 were as follows:

Note 13. Employee Benefit Plans

Pension Plans

The Company maintains the Bremer Retirement Plan (“Pension Plan”), which is a qualified defined benefit pension plan designed to provide retirement benefits to substantially all the employees of the Company, its subsidiaries, and OBT. An employee who has attained the age of 21 and completed 1,000 hours of service within a 12-month period shall become a participant in the Pension Plan on the next semiannual entry date. In addition, the Company has a Supplemental Executive Retirement Plan (“SERP”), an unfunded plan designed to supplement the benefits determined under the Pension Plan for certain highly compensated employees of the Company to the extent the benefits under the Pension Plan are capped by compensation limits.

Other Postretirement Benefits

The Company provides certain retiree health care benefits relating primarily to medical insurance co-payments to retired employees between the ages of 55 and 65. The Company amended the Company’s Retiree Medical Plan effective January 1, 2006, which gradually eliminated the medical premium subsidy for retired employees over a period of ten years ending December 31, 2015, while continuing to allow retired employees access to the Company’s group medical coverage. The Company accrues the cost of these benefits during the employees’ active service, and benefits are funded as incurred.

Pension Plans and Other Postretirement Benefits

The Company recognizes actuarial gains or losses and prior service costs or credits, and measures plan assets and pension obligations, and accumulated other comprehensive income or loss, net of tax, at December 31 of each year. The Company expects to amortize the following amounts from accumulated

TABLE OF CONTENTS

The accumulated benefit obligation for the Company’s pension plans was $263.2 million and $240.7 million at December 31, 2023 and 2022, respectively. Net pension expense for the plans at December 31 was as follows:

	Pension Benefits						Other Postretirement Benefits
Year Ended December 31 (Dollars in Thousands)	2023			2022			2023			2022
Service cost		$	7,608		$	12,400		$	215		$	287

Net periodic benefit cost (income) .		$	11,157		$	(4,833)		$	(199)		$	(78)

The components of net periodic benefit cost, other than the service cost component, are included in other noninterest expense in the consolidated statement of income.

Weighted average assumptions used to determine benefit obligations at December 31, as well as the weighted average assumptions used to determine net periodic benefit cost for the years ended December 31, were as follows:

	Pension Benefits				Other Postretirement Benefits
	2023		2022		2023		2022
Benefit Obligations at December 31
Discount rate		5.21%		5.59%		5.21%		5.59%
Rate of compensation increase		4.00%		4.00%		N/A		N/A
Net Periodic Benefit Cost for Years Ended December 31
Discount rate		5.59%		3.10%		5.59%		3.10%
Expected return on plan assets		7.00%		6.50%		N/A		N/A
Rate of compensation increase		4.00%		4.00%		N/A		N/A

The discount rate utilized to determine future pension obligations is based primarily on a review of current high-quality fixed-income securities that could be used to settle the obligations of the plan.

The December 31, 2023 assumption for the long-term rate of return on plan assets, which will be used to determine net periodic benefit cost for the year ended December 31, 2024, is 7.0%, representing the expected long-term rate of return on plan assets reflecting the average rate of earnings expected on the funds invested or to be invested to provide for the benefits included in the benefit obligation. The assumption was determined by reflecting expectations regarding future long-term rates of return for the investment portfolio, with consideration given to the distribution of investments by, and historical rates of return of, each individual asset class.

For purposes of other postretirement benefits measurements, the Company assumed health care trend rates at December 31, as follows:

	2023		2022
Current year trend		6.25%		6.50%
Ultimate year trend		5.00%		5.00%
Year of ultimate trend rates		2029		2029

These investments are valued based on net asset value per share as a practical expedient; fair values are provided to reconcile to total investment assets of the plans at fair value.

The Company’s long-term asset allocation targets are 75% return seeking assets and 25% liability-hedging fixed income. The return seeking assets allocation is distributed over a number of professionally managed comingled investment trusts and real estate investment trust. The Company regularly reviews the actual asset allocation and periodically rebalances the investments to the targeted allocation when considered appropriate. The Company believes that 7.0% is a reasonable long-term rate of return assumption for the pension plan assets for 2024, given the long-term asset allocation strategy and investment time horizon. During the years ended December 31, 2023 and 2022, the pension plan assets generated total composite returns of 11.2% and -30.5%, respectively. The Company will continue to evaluate the actuarial assumptions, including the expected rate of return, at least annually, and will adjust as necessary.

In developing strategic asset allocation guidelines for the plan, an emphasis is placed on the long-term characteristics of individual asset classes, the benefits of diversification among multiple asset classes, and the Company’s long-term return expectations for the plan. Consideration is also given to the proper level of risk of the plan, particularly with respect to the long-term nature of the plan’s liabilities and long-term investment horizon of plan assets.

The Company seeks to maintain an adequately funded Pension Plan, defined as having a fair market value of plan assets to projected benefit obligation ratio of at least 94% to 100%. This is generally achieved by making annual cash contributions to the plan in an amount at least equal to the current year’s calculated service cost. Contributions to the plan are intended to provide for benefits attributed to service to date and for those expected to be earned in the future.

The Company currently expects that there will be no minimum required contribution to the pension plan in 2024 under the provisions of the Pension Protection Act of 2006, as modified by the Worker, Retiree, and Employer Recovery Act of 2008. However, management may make a discretionary cash contribution to ensure that the plans remain adequately funded, and expects to make the following benefit payments, which reflect expected future service, as appropriate:

401(k) Plan

The 401(k) Plan is a defined contribution plan. The Company provides a 100% match of the first 1% to 5% of plan compensation the employee contributes on a pretax basis. Total employer contributions of $6.0 million and $5.9 million were made for the years ended December 31, 2023 and 2022, respectively.

Employee Stock Ownership Plan

The Employee Stock Ownership Plan is a defined contribution plan covering substantially all employees of the Company, and the plan holds 103,356 shares of Class A common stock of the Company. Contributions to the plan are made exclusively by the Company as determined by the annual cash needs of the plan and are credited to the individual accounts of the employees who are participants in the plan for the fiscal year the contribution is made. Contributions and forfeitures are allocated to participants on the basis of total compensation, defined as 100% of base pay and eligible commissions earned during the plan year, while dividends paid on allocated shares increase participant accounts. Contributions of $1.0 million and $1.5 million were made to this plan during the years ended December 31, 2023 and 2022, respectively.

The Company’s deferred tax assets represent the anticipated federal, and state tax benefits expected to be realized in future years upon the utilization of the underlying tax attributes comprising the balance. In management’s opinion, the deferred tax assets will be fully realized through future reversals of deferred tax liabilities along with future taxable income exclusive of existing deferred tax liabilities. Accordingly, no valuation allowance has been provided.

Liabilities for unrecognized tax benefits were $7.4 million and $1.2 million at December 31, 2023 and 2022, respectively. The Company is no longer subject to income tax examinations for years prior to 2020 for federal purposes and 2019 for state purposes.

Note 17. Commitments and Contingencies

The Company utilizes various off-balance-sheet instruments to satisfy the financing needs of customers. These instruments represent contractual obligations of the Company to provide funding, within a specified time period, to a customer. The following provides information regarding the outstanding commitments at December 31:

(Dollars in Thousands)	2023			2022
Loan commitments		$	3,054,683		$	3,421,432
Standby letters of credit			57,639			63,657

Loan commitments represent contractual agreements to provide funding to customers over a specified time period so long as there is no violation of any condition of the contract. These loans are generally operating lines of credit.

Standby letters of credit represent a conditional commitment to satisfy an obligation to a third party, generally to support public and private borrowing arrangements, on behalf of the customer.

The Company’s potential exposure to credit loss in the event of nonperformance by the other party is represented by the contractual amount of those instruments. The credit risk associated with letters of credit and loan commitments is substantially the same as extending credit in the form of a loan; therefore, the same credit policies apply in evaluating potential letters of credit or loan commitments. The amount of collateral obtained, if deemed necessary upon the extension of credit, is based on management’s credit evaluation. The type of collateral held varies, but includes real estate, accounts receivable, inventory, and productive assets. Management assesses unfunded commitments for credit risk and estimates a liability related to losses that may result from the assessed risk. The liability for unfunded commitments, included in accrued expenses and other liabilities on the consolidated balance sheet, was $3.1 million and $8.3 million at December 31, 2023 and 2022, respectively.

Other Commitments and Contingencies

Under contracts with service providers, the Company is obligated for future payments. Contractual future minimum payments over the term of the contracts are as follows:

2029 and later		14,796

The Company is routinely involved in legal actions that are incidental to the business of the Company. Although it is difficult to predict the ultimate outcome of these cases, management believes, based on discussions with counsel, that any ultimate liability will not materially affect the Company’s consolidated financial position or results of operations.

Note 18. Derivatives and Hedging Activities

Risk Management Objectives of Using Derivatives

The Company is exposed to certain risks arising from both its business operations and economic conditions. The Company principally manages its exposures to business and operational risks through management of its core business activities. The Company manages economic risks, including interest rate, liquidity, and credit risk, primarily by managing the amount and duration of its wholesale funding, investment portfolio, and the use of derivative financial instruments. Specifically, the Company enters into derivative financial instruments to manage exposures that arise from business activities that result in the receipt or payment of future known and uncertain cash amounts, the value of which are determined by interest rates. The Company’s derivative financial instruments are used to manage differences in the amount, timing, and duration of the Company’s known or expected cash receipts and its known or expected cash payments principally related to certain floating and fixed-rate borrowings. In addition, the Company may also utilize derivative financial positions to hedge changes in the fair value of certain related assets or liabilities and to accommodate the business requirements of its customers.

Fair Values of Derivative Instruments on the Consolidated Balance Sheet

Certain derivative exchanges have enacted a rule change which in effect results in the legal characterization of variation margin payments for certain derivative contracts as settlement of the derivatives mark-to-market exposure and not collateral. Accordingly, the Company’s reporting of certain derivatives reflects variation margin recorded on trades cleared through these exchanges as settled. The daily settlement of the derivative exposure does not change or reset the contractual terms of the instrument.

Derivatives are classified as other assets or other liabilities on the consolidated balance sheet.

Derivatives Designated as Hedging Instruments

Fair Value Hedges of Interest Rate Risk

The Company is exposed to changes in the fair value of certain of its fixed-rate obligations due to changes in the benchmark interest rate, SOFR. Interest rate swaps designated as fair value hedges involve the receipt of fixed-rate amounts from a counterparty in exchange for the Company making variable-rate payments over the life of the agreements without the exchange of the underlying notional amount. As of December 31, 2023, the Company did not have any interest rate contracts that were designated as fair value hedges.

For derivatives designated and that qualify as fair value hedges, the gain or loss on the derivative as well as the offsetting loss or gain on the hedged item attributable to the hedged risk are recognized in earnings. The Company includes the gain or loss on the hedged items in the same line item as the offsetting loss or gain on the related derivatives.

During 2021, the Company terminated an interest rate swap that was designated as a fair value hedge of interest rate risk associated the Company’s fixed rate subordinated notes. The interest rate swap, which had a notional value of $100.0 million, terminated with a settlement value of $5.0 million. The $5.0 million basis adjustment to the fixed rate subordinated notes’ carrying amount will be amortized as a reduction of interest expense between July 2021, the date of the interest rate swap termination, and December of 2024, the maturity date of the debt. Amortization of the basis adjustment totaled $1.5 million and $1.4 million during the years ended December 31, 2023 and 2022, respectively. The unamortized balance of the basis adjustment totaled $1.5 million and $3.0 million at December 31, 2023 and 2022, respectively. The amounts to be amortized during the next 12 months is $1.5 million.

Cash Flow Hedges of Interest Rate Risk

The Company’s objectives in using interest rate derivatives are to manage its exposure to interest rate movements. To accomplish this objective, the Company primarily uses interest rate swaps as part of its interest rate risk management strategy. Interest rate swaps designated as cash flow hedges involve the receipt of variable amounts from a counterparty in exchange for the Company making fixed payments over the life of the agreements without exchange of the underlying notional amount. The changes in the fair value of derivatives designated and that qualify as cash flow hedges is recorded in accumulated other comprehensive income or loss and is subsequently reclassified into earnings in the period that the hedged transaction affects earnings. As of December 31, 2023, the Company did not have any interest rate contracts designated as cash flow hedges.

During 2022, the Company terminated two interest rate swaps that were designated as cash flow hedges of interest rate risk associated with certain of the Company’s variable rate funding. The interest rate swaps, which had a combined notional value of $200.0 million, terminated at a settlement value of $8.1 million. This amount will be reclassified from accumulated other comprehensive income to interest expense between January 2022, the termination date, and April 2026, the original combined term of the interest rate swaps. A reduction to interest expense of $2.2 million was recorded related to these transactions during the year ended December 31, 2023. The accumulated other comprehensive income balance totaled $4.0 million and $6.3 million at December 31, 2023 and 2022, respectively. The amounts to be reclassified during the next 12 months is $2.2 million.

During 2019, the Company terminated an interest rate swap that was designated as a cash flow hedge of interest rate risk associated with certain of the Company’s variable rate loans. The interest rate swap, which had a notional value of $200.0 million, terminated at a settlement value of $6.6 million. This amount was reclassified from accumulated other comprehensive income to interest income on a straight-line basis between July 2019, the termination date, and March of 2023, the original term of the interest rate swap. Interest income of $0.4 million and $1.8 million was recorded related to this transaction during the years ended December 31, 2023 and 2022, respectively. The accumulated other comprehensive income balance totaled $0.0 million and $0.4 million at December 31, 2023 and 2022, respectively.

Derivatives Not Designated as Hedging Instruments

The Company executes interest rate derivatives with commercial banking customers to facilitate their respective risk management strategies. Those interest rate derivatives are simultaneously hedged by offsetting derivatives that the Company executes with a third party, such that the Company minimizes its net risk exposure resulting from such transactions. Interest rate derivatives associated with this program are reported on the consolidated balance sheet at fair value, with changes in fair value of both the customer derivatives and the offsetting derivatives recognized directly in net income. Amounts related to these activities are reflected as customer-related interest rate contracts within this footnote. Derivatives related to these activities are subject to credit risk associated with counterparties to the derivative contracts. The Company measures that credit risk using a credit valuation adjustment and includes it within the fair value of the derivative. Included within other noninterest income on the consolidated statement of income are amounts recorded related to credit valuation adjustments of $0.3 million in positive adjustments and $0.6 million in positive adjustments during the years ended December 31, 2023 and 2022, respectively.

Credit risk participation agreements arise when the Company contracts with other institutions, as a guarantor or beneficiary, to share the credit risk associated with certain interest rate swaps. These agreements provide for reimbursement of losses resulting from a third-party default on the underlying swap. Amounts related to these activities are reflected as customer-related credit contracts within this footnote. Amounts recorded within other noninterest income on the consolidated statement of income related to these activities were not material for the years ended December 31, 2023 and 2022.

As part of the Company’s risk management strategy through its mortgage banking activities, derivative instruments such as forward sales contracts are utilized. Changes in the fair value of these derivative instruments are recorded in mortgage banking and loan fees. Amounts related to these activities are reflected as mortgage banking forward contracts within this footnote.

F-43

TABLE OF CONTENTS

In the normal course of business through its mortgage banking activities, interest rate lock commitments arise related to agreements with customers regarding residential mortgage loans. Such commitments provide a specified interest rate for a specified time period to the customer. Where the Company intends to sell the resulting loan, authoritative accounting guidance requires that these commitments be recorded at fair value on the consolidated balance sheet. Changes in the fair value of these interest rate lock commitments are recorded in other noninterest income and are offset by the changes in the fair value of forward sales contracts. Amounts related to these activities are reflected as mortgage banking rate locks within this footnote. Amounts recorded within mortgage banking and loan fees on the consolidated statement of income related to these activities were $0.8 million in gains and $3.9 million in gains for the years ended December 31, 2023 and 2022, respectively.

Credit-Risk-Related Contingent Features

The Company has agreements with its derivative counterparties that contain a provision where if the Company defaults on any of its indebtedness, including default where repayment of the indebtedness has not been accelerated by the lender, then the Company could also be declared in default on its derivative obligations. The Company also has agreements with its derivative counterparties that contain a provision where if the Company fails to maintain its status as an adequately capitalized institution, the counterparty could terminate the derivative positions and the Company would be required to settle its obligations under the agreements. As of December 31, 2023, the termination value of derivatives in a net liability position, which includes accrued interest but excludes any adjustment for non- performance risk, related to these agreements was immaterial. The Company has minimum collateral posting thresholds with its derivative counterparties and has not posted any collateral at December 31, 2023. If the Company had breached any of these provisions at year end, it could have been required to settle its obligations under the agreements at the termination value.

Note 19. Common Stock

The Company has authorized 12,000,000 shares of Class A common stock and 10,800,000 shares of Class B common stock. The shares of Class A common stock have full rights to vote on all matters presented before the Company’s shareholders, including the election of the Company’s directors. The Class B common stock, all of which is held by OBT, is non-voting except with respect to certain extraordinary corporate transactions, upon which the holders would have the right to vote on an equivalent per-share basis with the holders of Class A common stock.

Each share of Class B common stock is convertible into one share of Class A common stock upon the occurrence of the following events: (i) at the affirmative election of a third party or entity, upon the transfer of Class B common stock from OBT to any third party or entity, or (ii) at the affirmative election of the holder of Class B common stock, if cash dividends have not been paid on Class A and Class B common stock with respect to any year in an amount equal to at least 5% of the Company’s net book value as of the last day of the immediately preceding year. The Company has reserved 10,800,000 shares of Class A common stock in the event of conversion of the Class B common stock.

At December 31, 2023 and 2022, 960,000 shares of redeemable Class A stock were issued and outstanding. At December 31, 2023, these shares were subject to redemption at a price of $120.71 per share, which was net book value. These shares are owned by employees and directors of the Company and its subsidiaries and the employee benefit plans of the Company. The employee holders of Class A common stock have the right to require the Company to purchase their shares upon their deaths, permanent disabilities, or retirements, while the Company has the option to purchase the shares from holders upon the occurrence of certain events, which include death, retirement, or termination of the employee’s employment. It is the Company’s intent that these 960,000 shares will continue to be held by employees, directors, and employee benefit plans of the Company and its subsidiaries and not be directly purchased by the Company or OBT.

On October 28, 2019, OBT delivered notice to the Company asserting that the trustees of OBT had sold 725,000 shares of the Company’s Class B common stock to 19 entities, each of which delivered a notice of an intent to convert such shares of Class B common stock into Class A common stock. As of December 31, 2023, the validity of these purported transactions was the subject of ongoing litigation. These consolidated financial statements do not reflect such transactions.

Note 20. Regulatory Matters

The Company is subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company’s consolidated financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company must meet specific capital guidelines that involve quantitative measures of the Company’s assets, liabilities, and certain off-balance sheet items as calculated under regulatory accounting practices. The Company’s capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors.

Quantitative measures established by regulation to ensure capital adequacy require the Company to maintain minimum amounts and ratios, as defined in the regulations and set forth in the following table, of total, common equity Tier I, and Tier I capital to risk-weighted assets, and of Tier I capital to average assets. Effective January 1, 2015, under a phase-in period, revised regulatory capital guidelines increased the minimum required ratios and established a capital conservation buffer. The capital conservation buffer adds 2.5% to the minimum Tier I Common Equity ratio in order to avoid constraints on capital distributions, such as dividends, and certain bonus compensation for executive officers. The Company is required to phase out the subordinated notes from Tier II capital over a 5 year period, beginning in December 2019. As of December 31, 2023, the Company meets all capital adequacy requirements to which it is subject.

The Federal Deposit Insurance Corporation Improvement Act (“FDICIA”) required the establishment of a capital- based supervisory system of prompt corrective action for all depository institutions. The Federal Reserve Board’s implementation of FDICIA defines “well-capitalized” institutions as those for which Tier I capital ratio equals or exceeds 8%, total risk-based capital ratio equals or exceeds 10%, and leverage ratio equals or exceeds 5%. Bremer Bank’s ratios in each of these categories met or exceeded the “well-capitalized” ratios at December 31, 2023

As an approved mortgage seller and servicer, Bremer Bank, through its mortgage banking division, is required to maintain various levels of shareholder’s equity, as specified by various agencies, including the United States Department of Housing and Urban Development, Government National Mortgage Association, Federal Home Loan Mortgage Corporation, and the Federal National Mortgage Association. At December 31, 2023, Bremer Bank met these requirements.

The following provides the Company’s and Bremer Bank’s actual capital amounts and ratios at December 31:

Federal law prevents the Company, its nonbank subsidiaries and OBT from borrowing from Bremer Bank unless the loans are secured by the statutorily required amount of collateral. Further, the secured loans that may be made by Bremer Bank are generally limited to 10% of Bremer Bank’s equity if made to the Company or any individual affiliate and 20% of Bremer Bank’s equity if made to all affiliates and the Company in the aggregate. At December 31, 2023 and 2022, Bremer Bank had not extended credit to the Company.

The payment of dividends by the Company to shareholders and the payment of dividends by Bremer Bank to the Company are both subject to various limitations by bank regulators, which include maintenance of certain minimum capital ratios as well as limitations based on the level of net income and dividends paid in recent periods.

Note 21. Fair Value

The Company uses fair value measurements for the initial recording of certain assets and liabilities, periodic remeasurement of certain assets and liabilities, and disclosures. Derivatives, available-for-sale investment securities, and MSRs are recorded at fair value on a recurring basis. Additionally, from time to time, the Company may be required to record at fair value other assets on a nonrecurring basis, such as LHFS, impaired loans, and OREO, and certain other assets and other liabilities. These nonrecurring fair value adjustments typically involve application of lower-of-cost-or-fair value accounting or impairment write-downs of individual assets.

Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. A fair value measurement reflects all the assumptions that market participants would use in pricing the asset or liability, including assumptions about the risk inherent in a particular valuation technique, the effect of a restriction on the sale or use of an asset and the risk of nonperformance. The Company groups its assets and liabilities measured at fair value into a three-level hierarchy for valuation techniques used to measure financial assets and financial liabilities at fair value. This hierarchy is based on whether the valuation inputs are observable or unobservable. These levels are:

F-46

TABLE OF CONTENTS

Fair Value Hierarchy			Definition
Level 1			Quoted prices in active markets for identical assets or liabilities. Level 1 includes U.S. Treasury securities.
Level 2			Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 2 includes debt securities that are traded less frequently than exchange-traded instruments and which are typically valued using third party pricing services; derivative contracts and other assets and liabilities.
Level 3			Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Level 3 assets and liabilities include financial instruments for which values are determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair value requires significant management judgment or estimation. This category includes MSRs and interest rate lock commitments.

When the Company changes its valuation inputs for measuring financial assets and financial liabilities at fair value, either due to changes in current market conditions or other factors, it may need to transfer those assets or liabilities to another level in the hierarchy based on the new inputs used. The Company recognizes these transfers at the end of the reporting period in which the transfers occur. During the years ended December 31, 2023 and 2022, there were no transfers of financial assets or financial liabilities between the hierarchy levels.

Recurring Fair Value Measurements

The following section describes the valuation methodologies used by the Company to measure financial assets and liabilities at fair value on a recurring basis. In addition, the following section includes an indication of the level of the fair value hierarchy in which the assets or liabilities are classified. Where appropriate, the description includes information about the valuation models and key inputs to those models. During the years ended December 31, 2023 and 2022, there were no significant changes to the valuation techniques used by the Company to measure fair value. The following table provides the balances of assets and liabilities measured at fair value on a recurring basis at December 31:

Available-For-Sale Securities

When quoted market prices for identical securities are available in an active market, these prices are used to determine fair value and these securities are classified within Level 1 of the fair value hierarchy. Level 1 investment securities include U.S. Treasury securities.

F-47

TABLE OF CONTENTS

For other securities, quoted market prices may not be readily available for the specific securities. When possible, the Company determines fair value based on market observable information, including quoted market prices for similar securities, inactive transaction prices, and broker quotes. These securities are classified within Level 2 of the fair value hierarchy. Level 2 valuations are generally provided by a third-party pricing service. The Company reviews the valuation methodologies utilized by the pricing service and, on a quarterly basis, reviews the security level prices provided by the pricing service against management’s expectation of fair value, based on changes in various benchmarks and market knowledge from recent trading activity, as well as comparisons to other independent secondary pricing sources. Level 2 investment securities include agency mortgage-backed securities, certain other asset-backed securities, obligations of state and political subdivisions, agency debt securities, and corporate debt securities.

The Company did not hold any available-for-sale securities that were classified within Level 3 at December 31, 2023 or 2022.

Mortgage Servicing Rights

MSRs are valued using a discounted cash flow methodology and are classified within Level 3. The Company determines fair value of the MSRs by projecting future cash flows using prepayment rates and other assumptions and discounts these cash flows using a market based discount rate. The MSR valuations, as well as the assumptions used, are developed with the assistance of a third party. Risks inherent in MSR valuation include higher than expected prepayment rates and/or delayed receipt of cash flows. There is minimal observable market activity for MSRs on comparable portfolios and, therefore, the determination of fair value requires significant management judgment. Refer to Note 7 for further information on MSR valuation assumptions.

Derivatives

The Company obtains the fair value of interest rate swaps from a third-party pricing service that uses an industry standard discounted cash flow methodology. In addition, credit valuation adjustments are incorporated in the fair values to account for potential non-performance risk. In adjusting the fair value of its interest rate swap contracts for the effect of non-performance risk, the Company has considered any applicable credit enhancements, such as collateral postings, thresholds, mutual puts, and guarantees. In conjunction with the FASB’s fair value measurement guidance, the Company made an accounting policy election to measure the credit risk of these derivative financial instruments, which are subject to master netting agreements, on a net basis by counterparty portfolio.

The Company has determined that the primary inputs used to value its interest rate swaps offered to qualified commercial borrowers fall within Level 2 of the fair value hierarchy, while the credit valuation adjustments associated with these derivatives utilize Level 3 inputs, such as estimates of current credit spreads. The Company has assessed the significance of the impact of the credit valuation adjustments on the overall valuation of its interest rate swaps and has determined that the credit valuation adjustment is not significant to the overall valuation of these derivatives. As a result, the Company classifies its interest rate swap valuations in Level 2 of the fair value hierarchy.

Mortgage interest rate lock commitments and forward sale contracts are valued based on the securities prices of similar collateral, term, rate, and delivery for which the loan is eligible to deliver in place of the particular security. The Company’s mortgage security prices are supplied by a market data vendor, which in turn accumulates prices from a broad list of securities dealers. Prices are processed through a mortgage pipeline management system that accumulates and segregates all interest rate lock commitment and forward sale transactions according to the similarity of various characteristics (maturity, term, rate, and collateral). Prices are matched to those positions that are deemed to be an eligible substitute or offset (i.e., deliverable) for a corresponding security observed in the market and adjusted for an assumed pull-through rate. As a result, the Company classifies its interest mortgage commitments in Level 3 of the fair value hierarchy.

Non-Recurring Fair Value Measurements

The following section describes the valuation methodologies used by the Company to measure financial assets and liabilities at fair value on a non-recurring basis. In addition, the following section

includes an indication of the level of the fair value hierarchy in which the assets or liabilities are classified. Where appropriate, the description includes information about the valuation models and key inputs to those models. During the years ended December 31, 2023 and 2022, there were no significant changes to the valuation techniques used by the Company to measure fair value on a nonrecurring basis. The following table provides the balances of assets and liabilities measured at fair value on a non-recurring basis at December 31:

(Dollars in Thousands)	Level 1			Level 2			Level 3			Total

OREO			—			—			273			273
Total assets		$	—		$	—		$	51,431		$	51,431

Impaired Loans

Impaired loans are recorded at the loan’s observable market prices, the estimated fair value of the collateral for collateral-dependent loans, or the present value of the expected future cash flows discounted using market based credit spreads of comparable debt instruments of the specific borrower or comparable borrowers. Appraised values, adjusted for management’s assumptions relating to costs to hold, maintain, and sell the property, are generally used on real estate collateral-dependent impaired loans. Given the significant assumptions used in the valuation, impaired loans are included within Level 3 of the fair value hierarchy.

Other Real Estate Owned

The fair value of OREO is based on third party appraisals, net of estimated selling costs. Given the significant assumptions used in the valuation, OREO is included within Level 3 of the fair value hierarchy.

Loans Held for Sale

LHFS, which consist primarily of current production of certain first-lien residential mortgage loans, are carried at the lower of cost or estimated fair value. Fair value is estimated using observable inputs, primarily actual sale experience as well as secondary market price quotes. The Company did not record any adjustments to LHFS during the years ended December 31, 2023 or 2022, as fair value approximated carrying value at December 31, 2023 and 2022. Given that fair value is based on observable market prices, LHFS would be classified within Level 2 of the fair value hierarchy. The Company had recorded loans held for sale of $10.3 million and $11.9 million at December 31, 2023 and 2022, respectively.

Disclosures About Fair Value of Financial Instruments

Cash, Cash Equivalents, and Due from Banks

The carrying value of cash, cash equivalents, and due from banks approximates fair value due to the relatively short period of time between the origination of the instruments and their expected realization. These amounts are classified within Level 1.

Held-To-Maturity Securities

For other held-to-maturity securities, quoted market prices may not be readily available for the specific securities. When possible, the Company determines fair value based on market observable information, including quoted market prices for similar securities, inactive transaction prices, and broker quotes. These securities are classified within Level 2 of the fair value hierarchy. Level 2 valuations are generally provided by a third party pricing service. The Company reviews the valuation methodologies utilized by the pricing service and, on a quarterly basis, reviews the security level prices provided by the pricing service against management’s expectation of fair value, based on changes in various benchmarks and market knowledge from recent trading activity, as well as comparisons to other independent secondary pricing sources. Level 2 investment securities include agency mortgage-backed securities. The Company did not hold any held-to-maturity securities that were classified within Level 3 at December 31, 2023 or 2022.

Loans Held for Investment

The LHFI portfolio consists of both variable and fixed-rate obligations, the fair value of which was estimated using discounted cash flow analyses and other valuation techniques. To calculate discounted cash flows, the loans were aggregated into pools of similar types and expected repayment terms. The expected cash flows of loans considered historical prepayment experience and estimated credit losses for non-performing loans and were discounted using estimated market discount rates that reflect the credit and interest rate risk inherent in the loan type. In addition, when computing the estimated fair values for loans, the best estimate of losses inherent in the portfolio is deducted. Given the significant assumptions used in the valuation, LHFI is included within Level 3.

Deposits

The estimated fair value of deposits with no stated maturity, such as noninterest-bearing savings and money market checking accounts, is the amount payable on demand. The fair value of time deposits is estimated using the rates currently offered for deposits of similar remaining maturities. Deposits are included within Level 2.

Short-Term Borrowings

Short-term borrowings consist of federal funds, repurchase agreements, and FHLB borrowings. For variable-rate borrowings, fair value approximates carrying value. For fixed-rate borrowings, the fair value is determined by discounting future cash flows at current rates for borrowings with similar remaining maturities. Short-term borrowings are included within Level 2.

Long-Term Debt

For fixed-rate debt, the fair value is determined by discounting future cash flows at current rates for debt with similar remaining maturities and call features or by using market prices for similar assets. For variable-rate debt, fair value is determined by using market prices for similar assets. Long-term debt is included within Level 2.

Off-Balance Sheet Financial Instruments

The Company estimates the fair value of loan commitments and letters of credit based on the related amount of unamortized deferred commitment fees adjusted for probable losses from these arrangements. Substantially all of these commitments have floating rates and do not expose the Company to interest rate risk. The fair value of these unfunded commitments is approximately equal to their carrying value, which was $3.1 million and $8.3 million at December 31, 2023 and 2022, respectively.

Note 22. Subsequent Events

The Company evaluated all subsequent event activity through March 26, 2024 (the date the accompanying financial statements were available to be issued) and concluded that no subsequent events have occurred that would require recognition in the financial statements or disclosure in the notes to the financial statements.

TABLE OF CONTENTS

herein to a “certificate” representing shares of Parent Common Stock shall be deemed to include, unless the context otherwise requires, reference to book-entry account statements relating to the ownership of shares of Parent Common Stock) representing the number of whole shares of Parent Common Stock which such shares of Company Common Stock represented by such Certificate have been converted into the right to receive pursuant to Section 1.5(a), (ii) cash in lieu of fractional shares which the shares of Company Common Stock represented by such Certificate have been converted into the right to receive pursuant to Section 1.5(a) and Section 2.2(e), without any interest thereon, and (iii) any dividends or distributions which the holder thereof has the right to receive pursuant to Section 2.2. Certificates previously representing shares of Company Common Stock shall be exchanged for the Merger Consideration and the other amounts specified in the immediately preceding sentence upon the surrender of such Certificates in accordance with Section 2.2, without any interest thereon. If, prior to the Effective Time, the outstanding shares of Parent Common Stock or Company Common Stock shall have been increased, decreased, changed into or exchanged for a different number or kind of shares or securities as a result of a reorganization, recapitalization, reclassification, stock dividend, stock split, reverse stock split, or other similar change in capitalization, or there shall be any extraordinary dividend or distribution, an appropriate and proportionate adjustment shall be made to the Merger Consideration to give the Company and the holders of Company Common Stock the same economic effect as contemplated by this Agreement prior to such event; provided that nothing contained in this sentence shall be construed to permit the Company or Parent to take any action with respect to the outstanding shares of Parent Common Stock or Company Common Stock, as applicable, that is expressly prohibited by the terms of this Agreement.

(c) Notwithstanding anything in this Agreement to the contrary, at the Effective Time, all shares of Company Common Stock that are owned by the Company as treasury stock or owned by the Company, Parent or Merger Sub (in each case other than shares (i) held in trust accounts, managed accounts, mutual funds and the like, or otherwise held in a fiduciary or agency capacity that are beneficially owned by third parties, or (ii) held, directly or indirectly, as a result of debts previously contracted) shall be cancelled and cease to exist and no Merger Consideration shall be delivered or exchanged therefor.

(a) Notwithstanding any provision of this Agreement to the contrary, other than as provided in this Section 1.6, any shares of Company Common Stock that are issued and outstanding immediately prior to the Effective Time and are held by a holder who (i) has duly and validly demanded appraisal of such shares in connection with the Merger in accordance with Minnesota law and (ii) as of the Effective Time, has not effectively withdrawn or lost such appraisal rights (through failure to perfect or otherwise) (such shares, “Dissenting Shares”) shall not be converted into or represent the right to receive any portion of the consideration to be paid pursuant to Section 1.5 but instead shall be converted into the right to receive only such consideration as may be determined to be due with respect to such Dissenting Shares under Minnesota law. From and after the Effective Time, the Dissenting Shares shall no longer be outstanding and shall automatically be canceled and retired and shall cease to exist, and a holder of Dissenting Shares shall not be entitled to exercise any of the voting rights or other rights of a shareholder of the Surviving Entity.

(b) Notwithstanding the provisions of Section 1.6(a), if any holder of Company Common Stock who has duly and validly demanded appraisal of such shares in connection with the Merger in accordance with Minnesota law effectively withdraws or loses such appraisal rights (through failure to perfect or otherwise), then such shares shall no longer be Dissenting Shares and, as of the later of the Effective Time and the occurrence of such withdrawal or loss, such shares shall automatically be converted into the right to receive, without interest, the consideration to be paid pursuant to Section 1.5 hereto with respect to such shares pursuant to and in accordance with this Agreement.

(c) The Company shall give Parent reasonably prompt written notice of the receipt of any written notice of any demand for appraisal for any Company Common Stock, withdrawals of such demands or any intent to demand or withdraw the foregoing, and any other instruments served pursuant to Minnesota law and received by the Company that relate to any such demand for appraisal (each, an “Appraisal Demand”), and Parent shall have the right to participate in all negotiations and proceedings

A-5

TABLE OF CONTENTS

2.2 Exchange of Shares.

(a) As promptly as practicable after the Effective Time, but in no event later than five (5) business days thereafter, Parent shall cause the Exchange Agent to mail to each holder of record of one or more Certificates representing shares of Company Common Stock immediately prior to the Effective Time that have been converted at the Effective Time into the right to receive the Merger Consideration pursuant to Article I, a letter of transmittal and instructions for use in effecting the surrender of the Certificates in exchange for the Merger Consideration, and any cash in lieu of fractional shares, which the shares of Company Common Stock represented by such Certificate or Certificates shall have been converted into the right to receive pursuant to this Agreement as well as any dividends or distributions to be paid pursuant to Section 2.2(b). Upon proper surrender of a Certificate or Certificates for exchange and cancellation to the Exchange Agent, together with such properly completed letter of transmittal, duly executed, the holder of such Certificate or Certificates shall be entitled to receive in exchange therefor, as applicable, (i) a New Certificate representing that number of whole shares of Parent Common Stock to which such holder of Company Common Stock shall have become entitled pursuant to the provisions of Article I and (ii) a check representing the amount of (A) the aggregate Cash Merger Consideration to which such holder of Company Common Stock shall have become entitled pursuant to the provisions of Article I, (B) any cash in lieu of fractional shares which such holder has the right to receive in respect of the shares of Company Common Stock represented by the Certificate or Certificates surrendered pursuant to the provisions of this Article II, and (C) any dividends or distributions which the holder thereof has the right to receive pursuant to this Section 2.2, and the Certificate or Certificates so surrendered shall forthwith be cancelled. No interest will be paid or accrued on any Cash Merger Consideration, cash in lieu of fractional shares or dividends or distributions payable to holders of Certificates. Until surrendered as contemplated by this Section 2.2, each Certificate (other than Certificates with respect to Dissenting Shares) shall be deemed at any time after the Effective Time to represent only the right to receive, upon surrender, the Merger Consideration and any cash in lieu of fractional shares or in respect of dividends or distributions as contemplated by this Section 2.2.

(b) No dividends or other distributions declared with respect to Parent Common Stock shall be paid to the holder of any unsurrendered Certificate until the holder thereof shall surrender such Certificate in accordance with this Article II. After the surrender of a Certificate in accordance with this Article II, the record holder thereof shall be entitled to receive any such dividends or other distributions, without any interest thereon, which theretofore had become payable with respect to the whole shares of Parent Common Stock which the shares of Company Common Stock represented by such Certificate have been converted into the right to receive.

(c) If any New Certificate representing shares of Parent Common Stock is to be issued in a name other than that in which the Certificate or Certificates surrendered in exchange therefor is or are registered, it shall be a condition of the issuance thereof that the Certificate or Certificates so surrendered shall be properly endorsed (or accompanied by an appropriate instrument of transfer) and otherwise in proper form for transfer, and that the person requesting such exchange shall pay to the Exchange Agent in advance any transfer or other similar Taxes required by reason of the issuance of a certificate representing shares of Parent Common Stock in any name other than that of the registered holder of the Certificate or Certificates surrendered, or required for any other reason, or shall establish to the satisfaction of the Exchange Agent that such Tax has been paid or is not payable.

(d) After the Effective Time, there shall be no transfers on the stock transfer books of the Company of the shares of Company Common Stock that were issued and outstanding immediately prior to the Effective Time. If, after the Effective Time, Certificates representing such shares (other than Certificates with respect to Dissenting Shares) are presented for transfer to the Exchange Agent, they shall be cancelled and exchanged for the Merger Consideration and cash in lieu of fractional shares and dividends or distributions as provided in this Article II.

(e) Notwithstanding anything to the contrary contained herein, no certificates or scrip representing fractional shares of Parent Common Stock shall be issued upon the surrender for exchange of Certificates, no dividend or distribution with respect to Parent Common Stock shall be payable on or with respect to any fractional share, and such fractional share interests shall not entitle the owner thereof to vote or to any other rights of a shareholder of Parent. In lieu of the issuance of any

A-6

TABLE OF CONTENTS

such fractional share, Parent shall pay to each former shareholder of the Company who otherwise would be entitled to receive such fractional share an amount in cash (rounded to the nearest cent) determined by multiplying (i) the average of the closing-sale prices of Parent Common Stock on the NASDAQ Stock Market LLC (“NASDAQ”) as reported by the Wall Street Journal for the five (5) full trading days ending on the trading day immediately preceding the Closing Date by (ii) the fraction of a share (rounded to the nearest one-thousandth when expressed in decimal form) of Parent Common Stock which such holder would otherwise be entitled to receive pursuant to Section 1.5. The parties acknowledge that payment of such cash consideration in lieu of issuing fractional shares is not separately bargained-for-consideration, but merely represents a mechanical rounding off for the purposes of avoiding the expense and inconvenience that would otherwise be caused by the issuance of such fractional shares.

(f) Any portion of the Exchange Fund that remains unclaimed by the shareholders of the Company for twelve (12) months after the Effective Time shall be paid to Parent. Any former shareholder of the Company that has not theretofore complied with this Article II shall thereafter look only to Parent for payment of the Merger Consideration, cash in lieu of fractional shares and any unpaid dividends and distributions on the Parent Common Stock deliverable in respect of each former share of Company Common Stock such former shareholder holds as determined pursuant to this Agreement, in each case, without any interest thereon. Notwithstanding the foregoing, none of Parent, the Company, the Surviving Entity, the Exchange Agent or any other person shall be liable to any former holder of shares of Company Common Stock for any amount delivered in good faith to a public official pursuant to applicable abandoned property, escheat or similar laws.

(g) Each of Parent and the Exchange Agent (each, a “Withholding Agent”) shall be entitled to deduct and withhold from any consideration otherwise payable pursuant to this Agreement such amounts as it is required to deduct and withhold with respect to the making of such payment under the Code or any provision of state, local or foreign Tax law; provided, that such Withholding Agent shall make commercially reasonable efforts to provide notice to the applicable payee of its intent to deduct or withhold and the basis for such deduction or withholding before any such deduction or withholding is made, and reasonably cooperate with such payee in order to eliminate or to reduce any such deduction or withholding, including providing a reasonable opportunity for such payee to provide forms or other evidence that would mitigate, reduce or eliminate such deduction or withholding. To the extent that amounts are so withheld, such withheld amounts (i) will be paid over by the applicable Withholding Agent to the appropriate governmental authority and (ii) will be treated for all purposes of this Agreement as having been paid to the person in respect of which the deduction and withholding was made.

(h) In the event any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such Certificate to be lost, stolen or destroyed and, if required by Parent, the posting by such person of a bond in such amount as Parent may determine is reasonably necessary as indemnity against any claim that may be made against it with respect to such Certificate, the Exchange Agent will issue in exchange for such lost, stolen or destroyed Certificate the Merger Consideration, and any cash in lieu of fractional shares and dividends or distributions deliverable in respect thereof pursuant to this Agreement.

on its face (notwithstanding the absence of a specific cross-reference) from a reading of the disclosure that such disclosure applies to such other sections, the Company hereby represents and warrants to Parent as follows:

3.1 Corporate Organization.

(a) The Company is a corporation duly organized, validly existing and in good standing under the laws of the State of Minnesota and is a bank holding company duly registered with the Board of Governors of the Federal Reserve System (the “Federal Reserve Board”) under the Bank Holding Company Act of 1956, as amended (the “BHC Act”). The Company has the corporate power and authority necessary to own or lease all of its properties and assets and to carry on its business as it is now being conducted. The Company is duly licensed or qualified to do business and in good standing in each jurisdiction in which the nature of the business conducted by it or the character or location of the properties and assets owned or leased by it makes such licensing, qualification or standing necessary, except where the failure to be so licensed or qualified or to be in good standing would not, either individually or in the aggregate, reasonably be expected to have a Material Adverse Effect on the Company. As used in this Agreement, the term “Material Adverse Effect” means, with respect to Parent, the Company or the Surviving Entity, as the case may be, any effect, change, event, circumstance, condition, occurrence or development that, either individually or in the aggregate, has had or would reasonably be expected to have a material adverse effect on (i) the business, assets, results of operations or financial condition of such party and its Subsidiaries taken as a whole (provided that, with respect to this clause (i), Material Adverse Effect shall not be deemed to include the impact of (A) changes, after the date hereof, in U.S. generally accepted accounting principles (“GAAP”) or applicable regulatory accounting requirements or interpretations thereof, (B) changes, after the date hereof, in laws, rules or regulations of general applicability to companies in the industries in which such party and its Subsidiaries operate, or interpretations thereof by courts or Governmental Entities, (C) changes, after the date hereof, in global, national or regional political conditions (including any outbreak, continuation or escalation of acts of war (whether or not declared), cyberattacks, sabotage, an act of terrorism, military actions) or in economic or market (including equity, credit and debt markets, as well as changes in interest rates) conditions affecting the financial services industry generally and not specifically relating to such party or its Subsidiaries, (D) changes, after the date hereof, resulting from hurricanes, earthquakes, tornados, floods or other natural disasters, man-made disasters or any outbreak of any epidemic, pandemic or other public health event or emergencies (including any law, directive or guideline issued by a Governmental Entity in response thereto), (E) public disclosure of the execution of this Agreement, public disclosure or (except in the case of the representations contained in Sections 3.3(b), 3.4, 3.11(j), 4.3(b) and 4.4) consummation of the transactions contemplated hereby (including any effect on a party’s relationships with its customers or employees), actions expressly required or prohibited by this Agreement or actions taken with the prior written consent of Parent (in the case of the Company) or the Company (in the case of Parent), (F) a decline in the trading price of a party’s common stock, in and of itself, or the failure, in and of itself, to meet internal or published projections or forecasts (it being understood that the underlying cause of such decline or failure may be taken into account in determining whether a Material Adverse Effect has occurred, except to the extent otherwise excepted by this proviso), or (G) the expenses incurred by the Company or Parent in negotiating, documenting, effecting and consummating the transactions contemplated by this Agreement; except, with respect to subclauses (A), (B), (C) and (D), to the extent that the effects of such change are materially disproportionately adverse to the business, properties, assets, liabilities, results of operations or financial condition of such party and its Subsidiaries, taken as a whole, as compared to other companies in the industry in which such party and its Subsidiaries operate) or (ii)the ability of such party to timely consummate the transactions contemplated hereby. As used in this Agreement, the word “Subsidiary” shall have the meaning ascribed to it in Section 2(d) of the BHC Act. True and complete copies of the Company Charter and Company Bylaws, as in effect as of the date of this Agreement, have previously been made available by the Company to Parent.

it to be so qualified and in which the failure to be so qualified would reasonably be expected to have a Material Adverse Effect on the Company and (iii) has all requisite corporate power and authority necessary to own or lease its properties and assets and to carry on its business as now conducted. There are no restrictions on the ability of any Subsidiary of the Company to pay dividends or distributions except, in the case of a Subsidiary that is a regulated entity, for restrictions on dividends or distributions generally applicable to all such regulated entities. The deposit accounts of each Subsidiary of the Company that is an insured depository institution are insured by the Federal Deposit Insurance Corporation (the “FDIC”) through the Deposit Insurance Fund to the fullest extent permitted by law, all premiums and assessments required to be paid in connection therewith have been paid when due, and no proceedings for the termination of such insurance are pending or, to the knowledge of the Company, threatened.

TABLE OF CONTENTS

Regulatory Agencies and Governmental Entities which are necessary or advisable to consummate the transactions contemplated by this Agreement (including the Mergers and the Bank Merger), and to comply with the terms and conditions of all such permits, consents, approvals and authorizations of all such Regulatory Agencies and Governmental Entities. Without limiting the generality of the foregoing, as soon as practicable and in no event later than sixty (60) days after the date of this Agreement, Parent and the Company shall, and shall cause their respective Subsidiaries to, each prepare and file any applications, notices and filings required to be filed with any bank regulatory agency in order to obtain the Requisite Regulatory Approvals. Parent and the Company shall each use, and shall each cause their applicable Subsidiaries to use, reasonable best efforts to obtain each such Requisite Regulatory Approval as promptly as reasonably practicable. Parent and the Company shall have the right to review in advance, and, to the extent practicable, each will consult the other on, in each case subject to applicable laws relating to the exchange of information, all the information relating to the Company or Parent, as the case may be, and any of their respective Subsidiaries, which appears in any filing made with, or written materials submitted to, any third party or any Governmental Entity in connection with the transactions contemplated by this Agreement. In exercising the foregoing right, each of the parties hereto shall act reasonably and as promptly as practicable. The parties hereto agree that they will consult with each other with respect to the obtaining of all permits, consents, orders, approvals, waivers, non-objections and authorizations of all third parties and Governmental Entities necessary or advisable to consummate the transactions contemplated by this Agreement and each party will keep the other apprised of the status of matters relating to completion of the transactions contemplated hereby. Each party shall consult with the other in advance of any meeting or conference with any Governmental Entity in connection with the transactions contemplated by this Agreement and to the extent permitted by such Governmental Entity, give the other party and/or its counsel the opportunity to attend and participate in such meetings and conferences, in each case subject to applicable law; and provided that each party shall promptly advise the other party with respect to substantive matters that are addressed in any meeting or conference with any Governmental Entity which the other party does not attend or participate in, to the extent permitted by such Governmental Entity and applicable law.

(b) In furtherance and not in limitation of the foregoing, each of Parent and the Company shall use its reasonable best efforts to resolve any objection that may be asserted by any Governmental Entity with respect to this Agreement or the transactions contemplated hereby. Notwithstanding the foregoing, nothing contained in this Agreement shall be deemed to require Parent or the Company or any of their respective Subsidiaries, and neither Parent nor the Company nor any of their respective Subsidiaries shall be permitted (without the written consent of the other party), to take any action, or commit to take any action, or agree to any condition or restriction that would reasonably be expected to have a Material Adverse Effect on Parent and its Subsidiaries, taken as a whole, after giving effect to the Mergers (a “Materially Burdensome Regulatory Condition”).

(c) Parent and the Company shall, upon request, furnish each other with all information concerning themselves, their Subsidiaries, directors, officers and shareholders and such other matters as may be reasonably necessary or advisable in connection with the Proxy Statement, the S-4 and any other statement, filing, notice or application made by or on behalf of Parent, the Company or any of their respective Subsidiaries to any Governmental Entity in connection with the Mergers, the Bank Merger and the other transactions contemplated by this Agreement.

(d) To the extent permitted by applicable law, Parent and the Company shall promptly advise each other upon receiving any communication from any Governmental Entity whose consent or approval is required for consummation of the transactions contemplated by this Agreement that causes such party to believe that there is a reasonable likelihood that any Requisite Regulatory Approval will not be obtained or that the receipt of any such approval will be materially delayed. For the avoidance of doubt, Section 9.14 shall not preclude either party from fulfilling its obligation under this Section 6.1(d) to the extent permissible under applicable law.

A-37

TABLE OF CONTENTS

Merger, or those other authorizations, consents, orders, waivers, non-objections or approvals the failure of which to be obtained would, either individually or in the aggregate, have a Material Adverse Effect on Parent and its Subsidiaries, taken as a whole, after giving effect to the Mergers.

6.2 Access to Information.

(a) Upon reasonable notice and subject to applicable laws, each party, for the purposes of verifying the representations and warranties of the other party and preparing for the Mergers, the Bank Merger and the other matters contemplated by this Agreement, shall, and shall cause each of its Subsidiaries to, afford to the Representatives of the other party, access, during normal business hours during the period prior to the Effective Time, to all its properties, books, contracts, commitments, personnel, information technology systems, and records, provided that such investigation or requests shall not interfere unnecessarily with normal operations of the other party, and each party shall cooperate with the other party in preparing to execute after the Effective Time conversion or consolidation of systems, integration and business operations generally, and, during such period, each party shall, and shall cause its Subsidiaries to, make available to the other party (i) a copy of each report, schedule, registration statement, comment letter and other document filed or received by it during such period pursuant to the requirements of federal securities laws or federal or state banking laws (other than reports or documents that the other party is not permitted to disclose under applicable law), and (ii) all other information concerning its business, properties and personnel as the other party may reasonably request. Neither party nor any of its Subsidiaries shall be required to provide access to or to disclose information where such access or disclosure would violate or prejudice the rights of the party’s customers, jeopardize the attorney-client privilege of the institution in possession or control of such information (after giving due consideration to the existence of any common interest, joint defense or similar agreement between the parties) or contravene any law, rule, regulation, order, judgment, decree, fiduciary duty or binding agreement entered into prior to the date of this Agreement. The parties hereto will make appropriate substitute disclosure arrangements under circumstances in which the restrictions of the preceding sentence apply.

(b) Parent and the Company shall hold all information furnished by or on behalf of the other party or any of such other party’s Subsidiaries or Representatives pursuant to Section 6.2(a) in confidence to the extent required by, and in accordance with, the provisions of the confidentiality agreement, dated September 7, 2024, between Parent and the Company (the “Confidentiality Agreement”).

(c) No investigation by either of the parties or their respective Representatives shall affect or be deemed to modify or waive the representations and warranties of the other set forth herein. Nothing contained in this Agreement shall give either party, directly or indirectly, the right to control or direct the operations of the other party prior to the Effective Time. Prior to the Effective Time, each party shall exercise, consistent with the terms and conditions of this Agreement, complete control and supervision over its and its Subsidiaries’ respective operations.

6.3 Shareholder Approvals. The Company shall call, give notice of, establish a record date, convene and hold a meeting of its shareholders (the “Company Meeting”) as soon as reasonably practicable after the S-4 is declared effective for the purpose of obtaining the Requisite Company Vote required in connection with this Agreement and the Merger and, if so desired and mutually agreed, upon other matters of the type customarily brought before an annual or special meeting of shareholders to approve a merger agreement. Subject to the remainder of this Section 6.3, the Company shall use its reasonable best efforts to obtain from its shareholders the Requisite Company Vote, including by communicating to the shareholders of the Company its recommendation (and including such recommendation in the Proxy Statement) that, the shareholders of the Company approve this Agreement and the Merger (the “Company Board Recommendation”). Subject to the remainder of this Section 6.3, the Company and its Board of Directors shall not (a) withhold, withdraw, modify or qualify in a manner adverse to Parent the Company Board Recommendation, (b) fail to make the Company Board Recommendation in the Proxy Statement, (c) adopt, approve, recommend or endorse an Acquisition Proposal or publicly announce an intention to adopt, approve, recommend or endorse an Acquisition Proposal, (d) fail to publicly and without qualification (i) recommend against any Acquisition Proposal or (ii) reaffirm the Company Board Recommendation, within ten (10) business days (or such fewer number of days as remains prior to the Company Meeting) after an Acquisition

A-38

TABLE OF CONTENTS

Proposal is made public or any request by Parent to do so, or (e) publicly propose to do any of the foregoing (any of the foregoing a “Recommendation Change”). However, subject to Section 8.1 and Section 8.2, if the Board of Directors of the Company, after receiving the advice of its outside counsel, and, with respect to financial matters, its financial advisors, determines in good faith that it would be more likely than not to result in a violation of its fiduciary duties under applicable law to make or continue to make the Company Board Recommendation, the Board of Directors of the Company may (but shall not be required to), prior to the receipt of the Requisite Company Vote, submit this Agreement to its shareholders without recommendation (which, for the avoidance of doubt, shall constitute a Recommendation Change) (although the resolutions approving this Agreement as of the date hereof may not be rescinded or amended), in which event the Board of Directors of the Company may communicate the basis for its lack of a recommendation to its shareholders in the Proxy Statement or an appropriate amendment or supplement thereto to the extent required by law; provided that the Board of Directors of the Company may not take any of the actions under this sentence unless (A) it gives Parent at least three (3) business days’ prior written notice of its intention to take such action and a reasonable description of the event or circumstances giving rise to its determination to take such action (including, in the event such action is taken in response to an Acquisition Proposal, the latest material terms and conditions of, and the identity of the third party making, any such Acquisition Proposal, or any amendment or modification thereof, or describe in reasonable detail such other event or circumstances) and (B) at the end of such notice period, the Board of Directors of the Company takes into account any amendment or modification to this Agreement proposed by Parent and after receiving the advice of its outside counsel, and, with respect to financial matters, its financial advisor, determines in good faith that it would nevertheless be more likely than not to result in a violation of its fiduciary duties under applicable law to continue to make the Company Board Recommendation. Any material amendment to any Acquisition Proposal will be deemed to be a new Acquisition Proposal for purposes of this Section 6.3 and will require a new notice period as referred to in this Section 6.3. The Company shall adjourn or postpone the Company Meeting, if, as of the time for which such meeting is originally scheduled there are insufficient shares of Company Common Stock represented (either in person or by proxy) to constitute a quorum necessary to conduct the business of such meeting, or if on the date of such meeting the Company has not received proxies representing a sufficient number of shares necessary to obtain the Requisite Company Vote, and subject to the terms and conditions of this Agreement, the Company shall continue to use reasonable best efforts to solicit proxies from its shareholders in order to obtain the Requisite Company Vote. Notwithstanding anything to the contrary herein, unless this Agreement has been terminated in accordance with its terms, the Company Meeting shall be convened and this Agreement shall be submitted to the shareholders of the Company at the Company Meeting for the purpose of voting on the approval of such proposal and the other matters contemplated hereby, and nothing contained herein shall be deemed to relieve the Company of such obligation.

6.4 Legal Conditions to Mergers. Subject in all respects to Section 6.1 of this Agreement, each of Parent and the Company shall, and shall cause its Subsidiaries to, use their reasonable best efforts (a) to take, or cause to be taken, all actions necessary, proper or advisable to comply promptly with all legal and regulatory requirements that may be imposed on such party or its Subsidiaries with respect to the Mergers and the Bank Merger and, subject to the conditions set forth in Article VII, to consummate the transactions contemplated by this Agreement, and (b) to obtain (and to cooperate with the other party to obtain) any material consent, authorization, order or approval of, or any exemption by, any Governmental Entity and any other third party that is required to be obtained by the Company or Parent or any of their respective Subsidiaries in connection with the Mergers, the Bank Merger and the other transactions contemplated by this Agreement.

6.5 Stock Exchange Listing. Parent shall cause the shares of Parent Common Stock to be issued in the Merger to be approved for listing on NASDAQ, subject to official notice of issuance, prior to the Effective Time.

6.6 Employee Matters.

(a) During the period commencing at the Effective Time and ending on the first anniversary of the Closing Date, Parent shall provide each employee of the Company and its Subsidiaries who continues to be employed by Parent or its Subsidiaries immediately following the Effective Time (collectively, the “Continuing Employees”) with (i) a base salary or base wage rate, as applicable, that is no less

A-39

TABLE OF CONTENTS

favorable than the base salary or base wage rate, as applicable, provided by the Company or its Subsidiaries to such Continuing Employee immediately prior to the Effective Time; (ii) short-term, annual and long-term incentive compensation target opportunities that are no less favorable, in the aggregate, than the short-term, annual and long-term incentive compensation target opportunities provided by the Company or its Subsidiaries to such Continuing Employee immediately prior to the Effective Time; and (iii)other compensation and employee benefits that are no less favorable, in the aggregate, to the other compensation and employee benefits (excluding defined benefit pension plans benefits and ESOP benefits) provided by the Company or its Subsidiaries to such Continuing Employee immediately prior to the Effective Time. Without limiting the immediately preceding sentence, Parent shall, or shall cause one of its Subsidiaries to, provide to each Continuing Employee whose employment terminates during the one (1)-year period following the Closing Date with the same severance benefits that are provided under and pursuant to the Old National Bancorp Severance Pay Plan (as provided to the Company prior to the date hereof), including, for the avoidance of doubt, the “Additional Severance Benefits” set forth in Section 4.3 of such plan; provided that such severance benefits will be determined (A) without taking into account any reduction after the Closing in compensation paid to such Continuing Employee and (B) taking into account each Continuing Employee’s service with the Company and its Subsidiaries (and any predecessor entities) prior to the Closing (based on the Continuing Employee’s original hire date as reflected in the Company’s records), and, on or after the Closing, Parent and its Subsidiaries.

(b) With respect to any employee benefit plans of Parent or its Subsidiaries in which any Continuing Employees become eligible to participate on or after the Effective Time (the “New Plans”), Parent shall: (i) waive all pre-existing conditions, exclusions and waiting periods with respect to participation and coverage requirements applicable to such employees and their eligible dependents under any New Plans, except to the extent such waiting periods would apply under the analogous Company Benefit Plan; (ii) use commercially reasonable efforts to provide each such employee and their eligible dependents with credit for any eligible expenses incurred by such employee or dependent prior to the Effective Time under a Company Benefit Plan (to the same extent that such credit was given under the analogous Company Benefit Plan prior to the Effective Time) in satisfying any applicable deductible, co-payment or out-of-pocket requirements under any New Plans that provide health care benefits; and (iii) recognize all service of such employees with the Company and its Subsidiaries for all purposes in any New Plan to the same extent that such service was taken into account under the analogous Company Benefit Plan prior to the Effective Time; provided that the foregoing service recognition shall not apply to the extent it would result in duplication of benefits for the same period of service.

(c) Parent shall, or shall cause one of its Subsidiaries to, assume and honor all Company Benefit Plans in accordance with their terms. Parent hereby acknowledges that a “change in control” (or similar phrase) within the meaning of the Company Benefit Plans will occur at the Effective Time.

(d) The Company shall cause any 401(k) plan sponsored or maintained by the Company or any of its Subsidiaries, including, without limitation, the Bremer 401(k) Plan, Plan No. 002, (a “Company 401(k) Plan”) to be terminated effective as of the day immediately prior to the Effective Time and contingent upon the occurrence of the Closing pursuant to resolutions and required amendments (if any), the form and substance of which shall be subject to review and comment by Parent, which comments will be considered by the Company in good faith to the extent timely provided. The Continuing Employees shall be eligible to participate, effective as soon as administratively practicable following the Effective Time (but no later than the second payroll period following the Closing), in a 401(k) plan sponsored or maintained by Parent or one of its Subsidiaries (a “Parent 401 (k) Plan”). The Company and Parent shall take any and all actions as may be required to permit the Continuing Employees who are then actively employed to make rollover contributions to the Parent 401(k) Plan of “eligible rollover distributions” (with the meaning of Section 401(a)(31) of the Code) in the form of cash, Company Common Stock or notes (in the case of loans) or a combination thereof. Prior to the Effective Time, the Company or its Subsidiaries may make an employer contribution (at a level determined in the ordinary course of business consistent with past practice) to any Company 401(k) Plan for the year in which the Effective Time occurs or any prior year.

(e) The Company shall or shall have the plan administrator of the ESOP cooperate with the trustee of the ESOP to provide the ESOP participants with the opportunity to vote on the Merger

(h) Nothing in this Agreement shall confer upon any employee, director or consultant of the Company or any of its Subsidiaries or affiliates any right to continue in the employ or service of Parent, the Company, or any Subsidiary or affiliate thereof, or shall interfere with or restrict in any way the rights of the Company, Parent or any Subsidiary or affiliate thereof to discharge or terminate the services of any employee, director or consultant of the Company or any of its Subsidiaries or affiliates at any time for any reason whatsoever, with or without cause. Nothing in this Agreement shall be deemed to (i) establish, amend, or modify any Company Benefit Plan, New Plan or any other benefit or employment plan, program, agreement or arrangement, or (ii) alter or limit the ability of Parent or any of its Subsidiaries or affiliates to amend, modify or terminate any particular Company Benefit Plan, New Plan or any other benefit or employment plan, program, agreement or arrangement after the Effective Time. Without limiting the generality of Section 9.11, nothing in this Agreement, express or implied, is intended to or shall confer upon any person, including, without limitation, any current or former employee, director or consultant of the Company or any of its Subsidiaries or affiliates, any right, benefit or remedy of any nature whatsoever under or by reason of this Agreement.

6.7 Indemnification; Directors’ and Officers’ Insurance.

(a) From and after the Effective Time, Parent shall indemnify and hold harmless and shall advance expenses as incurred, in each case to the extent (subject to applicable law) such persons are indemnified or entitled to advancement of expenses as of the date of this Agreement by the Company pursuant to the Company Charter, the Company Bylaws, the governing or organizational documents of any Subsidiary of the Company or any contract in existence as of the date hereof and disclosed to Parent, each present and former director and officer of the Company and its Subsidiaries (in each case, when acting in such capacity) (collectively, the “Company Indemnified Parties”) against any costs or expenses (including reasonable attorneys’ fees), judgments, fines, losses, damages or liabilities incurred in connection with any threatened or actual claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative, whether arising before or after the Effective Time, arising out of the fact that such person is or was a director or officer of the Company or any of its Subsidiaries and pertaining to matters, acts or omissions existing or occurring at or prior to the Effective Time, including matters, acts or omissions occurring in connection with the approval of this Agreement and the transactions contemplated by this Agreement; provided that in the case of advancement of expenses, the Company Indemnified Party to whom expenses are advanced provides an undertaking to repay such advances if it is ultimately determined that such Company Indemnified Party is not entitled to indemnification. Parent shall reasonably cooperate with the Company Indemnified Party, and the Company Indemnified Party shall reasonably cooperate with Parent, in the defense of any such claim, action, suit, proceeding or investigation.

(b) For a period of six (6) years after the Effective Time, Parent shall maintain in effect the current policies of directors’ and officers’ liability insurance maintained by the Company (provided that Parent may substitute therefor policies with a substantially comparable insurer of at least the same

A-41

TABLE OF CONTENTS

coverage and amounts containing terms and conditions which are no less advantageous to the insured) with respect to claims against the present and former officers and directors of the Company or any of its Subsidiaries arising from facts or events which occurred at or before the Effective Time (including the transactions contemplated by this Agreement); provided that Parent shall not be obligated to expend, on an annual basis, an amount in excess of 300% of the current annual premium paid as of the date hereof by the Company for such insurance (the “Premium Cap”), and if such premiums for such insurance would at any time exceed the Premium Cap, then Parent shall cause to be maintained policies of insurance which provide the maximum coverage available at an annual premium equal to the Premium Cap. In lieu of the foregoing, the Company may, in consultation with Parent, obtain at or prior to the Effective Time a six-year “tail” policy under the Company’s existing directors and officers insurance policy providing equivalent coverage to that described in the preceding sentence if and to the extent that the same may be obtained for an amount that, in the aggregate, does not exceed the Premium Cap. If Parent or the Company purchases such a “tail policy,” Parent shall maintain in effect such “tail policy.”

(c) The obligations of Parent and the Company under this Section 6.7 shall not be terminated or modified after the Effective Time in a manner so as to adversely affect any Company Indemnified Party or any other person entitled to the benefit of this Section 6.7 without the prior written consent of the affected Company Indemnified Party or affected person.

(d) The provisions of this Section 6.7 shall survive the Effective Time and are intended to be for the benefit of, and shall be enforceable by, each Company Indemnified Party and his or her heirs and representatives. If Parent or any of its successors or assigns will consolidate with or merge into any other entity and not be the continuing or surviving entity of such consolidation or merger, transfer all or substantially all of its assets or deposits to any other entity or engage in any similar transaction, then in each case to the extent the obligations set forth in this Section 6.7 are not otherwise transferred and assumed by such successors and assigns by operation of law or otherwise, Parent will cause proper provision to be made so that the successors and assigns of Parent will expressly assume the obligations set forth in this Section 6.7.

6.8 Additional Agreements. In case at any time after the Effective Time any further action is necessary or desirable to carry out the purposes of this Agreement (including any merger between a Subsidiary of Parent, on the one hand, and a Subsidiary of the Company, on the other) or to vest Parent or the Surviving Entity with full title to all properties, assets, rights, approvals, immunities and franchises of any of the parties to the Mergers, the proper officers and directors of each party to this Agreement and their respective Subsidiaries shall take all such necessary action as may be reasonably requested by Parent.

6.9 Dividends. After the date of this Agreement, the Company shall coordinate with Parent the declaration of any dividends in respect of Company Common Stock and the record dates and payment dates relating thereto, it being the intention of the parties hereto that holders of Company Common Stock shall not receive two dividends, or fail to receive one dividend, in any quarter with respect to their shares of Company Common Stock and any shares of Parent Common Stock any such holder receives in exchange therefor in the Merger.

6.10 Advice of Changes. Parent and the Company (in such capacity, the “Notifying Party”) shall each promptly advise the other party of any effect, change, event, condition, occurrence or development (i) that has had or is reasonably likely to have a Material Adverse Effect on the Notifying Party or (ii) which the Notifying Party believes would or would be reasonably likely to cause or constitute a material breach of any of the Notifying Party’s representations, warranties or covenants contained herein that reasonably could be expected to give rise, either individually or in the aggregate, to the failure of a condition set forth in, if Parent is the Notifying Party, Section 7.1 or Section 7.3, or if the Company is the Notifying Party, Section 7.1 or Section 7.2; provided that the delivery of any notice pursuant to this Section 6.10 shall not cure any breach of, or noncompliance with, any other provision of this Agreement or limit the remedies available to the party receiving such notice; provided, further, that any failure to give notice in accordance with the foregoing with respect to any breach shall not be deemed to constitute a violation of this Section 6.10 or the failure of any condition set forth in Section 7.2 or Section 7.3 to be satisfied, or otherwise constitute

A-42

TABLE OF CONTENTS

a breach of this Agreement by the party failing to give such notice, in each case unless the underlying breach would independently result in a failure of the conditions set forth in Section 7.2 or Section 7.3 to be satisfied.

6.11 Acquisition Proposals.

(a) The Company agrees that it will not, and will cause its Subsidiaries and its and their officers, directors, employees, agents, advisors and representatives (collectively, “Representatives”) not to, directly or indirectly, (i) initiate, solicit, knowingly encourage or knowingly facilitate inquiries or proposals with respect to any Acquisition Proposal, (ii) engage or participate in any negotiations with any person concerning any Acquisition Proposal, (iii) provide any confidential or nonpublic information or data to, or have or participate in any discussions with, any person relating to any Acquisition Proposal, or (iv) unless this Agreement has been terminated in accordance with its terms, approve or enter into any term sheet, letter of intent, indication of interest, commitment, memorandum of understanding, agreement in principle, acquisition agreement, merger agreement or other agreement (whether written or oral, binding or non-binding) (other than a confidentiality agreement referred to and entered into in accordance with this Section 6.11(a)) in connection with or relating to any Acquisition Proposal, except in each case to notify a person that has made or, to the knowledge of the Company, is making any inquiries with respect to, or is considering making, an Acquisition Proposal, of the existence of the provisions of this Section 6.11(a). Notwithstanding the foregoing, in the event that after the date of this Agreement and prior to the receipt of the Requisite Company Vote, the Company receives an unsolicited bona fide written Acquisition Proposal that did not result from or arise in connection with a breach of this Section 6.11(a), the Company may, and may permit its Subsidiaries and its and its Subsidiaries’ Representatives to, furnish or cause to be furnished confidential or nonpublic information or data and participate in such negotiations or discussions with the person making the Acquisition Proposal if the Board of Directors of the Company concludes in good faith (after receiving the advice of its outside counsel, and with respect to financial matters, its financial advisors) that failure to take such actions would be more likely than not to result in a violation of its fiduciary duties under applicable law; provided that, prior to furnishing any confidential or nonpublic information permitted to be provided pursuant to this sentence, the Company shall have entered into a confidentiality agreement with the person making such Acquisition Proposal on terms no less favorable to it than the Confidentiality Agreement, which confidentiality agreement shall not provide such person with any exclusive right to negotiate with such party. The Company will, and will cause its Representatives to, immediately cease and cause to be terminated any activities, discussions or negotiations conducted before the date of this Agreement with any person other than Parent with respect to any Acquisition Proposal. The Company will promptly (within twenty-four (24) hours) advise Parent following receipt of any Acquisition Proposal or any inquiry which could reasonably be expected to lead to an Acquisition Proposal (including the terms and conditions of, and the identity of the person making, such inquiry or Acquisition Proposal), will provide Parent with an unredacted copy of any such Acquisition Proposal and any draft agreements, proposals or other materials received in connection with any such inquiry or Acquisition Proposal, and will keep Parent apprised of any related developments, discussions and negotiations on a current basis, including any amendments to or revisions of the terms of such inquiry or Acquisition Proposal. The Company shall use its reasonable best efforts to enforce any existing confidentiality or standstill agreements to which it or any of its Subsidiaries is a party in accordance with the terms thereof.

(b) Nothing contained in this Agreement shall prevent the Company or its Board of Directors from complying with Rule 14d-9 and Rule 14e-2 under the Exchange Act with respect to an Acquisition Proposal; provided that such rules will in no way eliminate or modify the effect that any action pursuant to such rules would otherwise have under this Agreement.

(c) As used in this Agreement, “Acquisition Proposal” shall mean, other than the transactions contemplated by this Agreement, any offer, proposal or inquiry relating to, or any third party indication of interest in, (i) any acquisition or purchase, direct or indirect, of twenty-five percent (25%) or more of the consolidated assets of the Company and its Subsidiaries or 25% or more of any class of equity or voting or nonvoting securities of the Company or its Subsidiaries whose assets, individually or in the aggregate, constitute twenty-five percent (25%) or more of the consolidated assets of the Company,

A-43

(ii) any tender offer (including a self-tender offer) or exchange offer that, if consummated, would result in such third party beneficially owning twenty-five percent (25%) or more of any class of equity or voting or nonvoting securities of the Company or its Subsidiaries whose assets, individually or in the aggregate, constitute twenty-five percent (25%) or more of the consolidated assets of the Company, or (iii) a merger, consolidation, share exchange, business combination, reorganization, recapitalization, liquidation, dissolution or other similar transaction involving the Company or its Subsidiaries whose assets, individually or in the aggregate, constitute twenty-five percent (25%) or more of the consolidated assets of the party.

6.12 Public Announcements. Parent and the Company agree that the initial press release with respect to the execution and delivery of this Agreement shall be a release that is mutually agreed to by the parties. Thereafter, each of the parties agrees that no public release or announcement or statement concerning this Agreement or the transactions contemplated hereby shall be issued by any party without the prior written consent of the other party (which consent shall not be unreasonably withheld, conditioned or delayed), except (i) as required by applicable law or the rules or regulations of any applicable Governmental Entity or stock exchange to which the relevant party is subject, in which case the party required to make the release or announcement shall consult with the other party about, and allow the other party reasonable time to comment on, such release or announcement in advance of such issuance or (ii) for such releases, announcements or statements that are consistent with other such releases, announcements or statements made after the date of this Agreement in compliance with this Section 6.12; provided that, in the case of any such public releases, announcements or statements issued by Parent, Parent shall only be required to provide the Company with the portions of such releases, announcements or statements that reference the Company or the transactions contemplated hereby.

6.13 Change of Method. Parent and the Company shall be empowered, upon their mutual agreement, at any time prior to the Effective Time, to change the method or structure of effecting the combination of the Company and Parent (including the provisions of Article I), if and to the extent they both deem such change to be necessary, appropriate or desirable; provided that unless this Agreement is amended by agreement of each party in accordance with Section 9.2, no such change shall (a) alter or change the Exchange Ratio or the amount of Cash Merger Consideration per share of Company Common Stock, (b) adversely affect the Tax treatment of the Company’s shareholders or Parent’s shareholders pursuant to this Agreement, (c) adversely affect the Tax treatment of the Company or Parent pursuant to this Agreement or (d) materially impede or delay the consummation of the transactions contemplated by this Agreement in a timely manner. The parties agree to reflect any such change in an appropriate amendment to this Agreement executed by both parties in accordance with Section 9.2.

6.14 Restructuring Efforts. If the Company shall have failed to obtain the Requisite Company Vote at the duly convened Company Meeting, or any adjournment or postponement thereof, each of the parties shall in good faith use its reasonable best efforts to negotiate a restructuring of the transactions contemplated by this Agreement (it being understood that neither party shall have any obligation to alter or change any material terms, including the Exchange Ratio, the amount of Cash Merger Consideration or the amount or kind of the consideration to be issued to holders of the capital stock of the Company as provided for in this Agreement or any term that would adversely affect the tax treatment of the transactions contemplated hereby in a manner adverse to such party or its shareholders) and/or resubmit this Agreement and the transactions contemplated hereby (or as restructured pursuant to this Section 6.14) to the Company’s shareholders for adoption or approval.

6.15 Takeover Statutes. None of the Company, Parent, Merger Sub or their respective Boards of Directors shall take any action that would cause any Takeover Statute to become applicable to this Agreement, the Mergers, or any of the other transactions contemplated hereby, and each shall take all necessary steps to exempt (or ensure the continued exemption of) the Mergers and the other transactions contemplated hereby from any applicable Takeover Statute now or hereafter in effect. If any Takeover Statute may become, or may purport to be, applicable to the transactions contemplated hereby, each party and the members of their respective Boards of Directors will grant such approvals and take such actions as are necessary so that the transactions contemplated by this Agreement may be consummated as promptly as practicable on the terms contemplated hereby and otherwise act to eliminate or minimize the effects of any Takeover Statute on any of the transactions contemplated by this Agreement, including, if necessary, challenging the validity or applicability of any such Takeover Statute.

November 25, 2024

Old National Bancorp
One Main Street
Evansville, Indiana 47708

Ladies and Gentlemen:

Caroline S. Johnson, Francis M. Miley, and Daniel C. Reardon, solely in their respective capacities as trustees of the Otto Bremer Trust, a trust created under trust instrument dated May 22, 1944 (the “Trust Instrument”) and governed by the laws of Minnesota (the “Trust”) (in such capacities, the “Trustees”), and not in their respective individual capacities, hereby acknowledge that Bremer Financial Corporation, a Minnesota corporation (the “Company”), Old National Bancorp, an Indiana corporation (“Parent”), and ONB Merger Sub, Inc., an Indiana corporation and a wholly-owned subsidiary of Parent (“Merger Sub”), have entered into an Agreement and Plan of Merger, dated as of the same date hereof (as amended or modified from time to time, the “Merger Agreement”), pursuant to which, among other things, Merger Sub will be merged with and into the Company, with the Company as the surviving corporation (the “Surviving Corporation”) in such merger (the “Merger”) and, immediately following the Merger, the Surviving Corporation will merge with and into Parent, with Parent as the surviving corporation of such Merger (the “Second Step Merger”, and together with the Merger, the “Mergers”). A copy of the Merger Agreement has been provided to the Trustees. Capitalized terms used but not defined herein are to be deemed to have the same meanings assigned to them in the Merger Agreement.

The Trustees further acknowledge that, as of the date hereof, they have determined that the consummation of the Mergers would be in the best interests of the Trust’s beneficiaries and purposes. As an inducement to and condition of Parent’s willingness to enter into the Merger Agreement, the Trustees hereby agree, represent and warrant as follows:

1. Owned Shares. As of the date hereof, the Trustees own (of record or beneficially) and have the full power and authority to vote 240,000 shares of Class A Company Common Stock and 10,075,000 shares of Class B Company Common Stock (collectively, the “Owned Shares”). For all purposes of this agreement, the Owned Shares will include any shares of Company Common Stock as to which the Trustees acquire beneficial or record ownership after the date hereof. The Owned Shares are owned by the Trustees free and clear of all encumbrances, voting arrangements and commitments of every kind, except as would not restrict the performance of the Trustees’ obligations or compliance with the restrictions under this agreement. The Trustees do not beneficially own any shares of Class A Company Common Stock or Class B Company Common Stock other than the Owned Shares.

2. Agreement to Vote Owned Shares. The Trustees agree that, at the Company Meeting or any other meeting or action of the shareholders of the Company, including a written consent solicitation, the Trustees will (a) appear at such meeting or otherwise cause the Owned Shares to be counted as present thereat for the purpose of establishing a quorum, (b) vote all of the Owned Shares (or otherwise provide a proxy, consent or voting instruction or direction) in favor of (i) approval of the Merger Agreement, the Mergers and any other matters required to be approved or adopted in order to effect the Mergers and the transactions contemplated by the Merger Agreement and (ii) the adjournment or postponement of the Company Meeting, (c) not initiate any proxy solicitation or undertake any other efforts against the Merger Agreement, the Mergers or the transactions contemplated by the Merger Agreement, and (d) not vote the Owned Shares (or otherwise provide a proxy or consent) in favor of, or otherwise support, approval of any Acquisition Proposal with respect to the Company or any action that is intended to, or could reasonably be expected to, impede, interfere with, or delay or otherwise adversely affect the Mergers or the transactions contemplated by the Merger Agreement. Notwithstanding anything to the contrary in this agreement, the parties acknowledge that (x) this agreement is entered into by the Trustees solely in their respective capacities as Trustees and as holders of the Owned Shares and that nothing in this agreement shall prevent any of the Trustees from discharging his or her fiduciary duties as a member of the Board of Directors of the Company,

and (y) the taking of any actions (or failures to act) by any of the undersigned in such person’s capacity as a member of the Board of Directors of the Company shall not be deemed to constitute a breach of this agreement.

3. Transfer of Owned Shares and Company Common Stock. From the date hereof until the Effective Time, the Trustees agree that they will not, without the prior written consent of Parent, directly or indirectly, sell, offer for sale, transfer, pledge, assign, encumber or otherwise dispose of, or enter into any contract, agreement, option, commitment, derivative or other arrangement or understanding with respect to any sale, offer for sale, transfer, pledge, assignment, encumbrance or other disposition (each, a “Transfer”) of any of the Owned Shares or the voting rights thereunder.

4. Further Assurances. The Trustees will take all reasonable actions and make all reasonable efforts, and will execute and deliver all such further agreements, documents, certificates, instruments, proxies and voting instructions as reasonably necessary, in order to fulfill their agreements and obligations contemplated hereby, including, without limitation, the agreement of the Trustees to vote the Owned Shares in accordance with Section 2 hereof.

5. No Solicitation. The Trustees agree that they shall not, and they shall direct and use their respective reasonable best efforts to cause their agents and representatives (including, without limitation, any investment banker, attorney or accountant retained by the Trustees on behalf of the Trust) not to, directly or indirectly, (a) initiate, solicit, knowingly encourage or knowingly facilitate any inquiries or proposals with respect to any Acquisition Proposal with respect to the Company, (b) engage or participate in any negotiations with any person concerning any Acquisition Proposal with respect to the Company, (c) provide any confidential or nonpublic information or data to, or have or participate in any discussions with, any person relating to an Acquisition Proposal with respect to the Company, (d) enter into any term sheet, letter of intent, indication of interest, commitment, memorandum of understanding, agreement in principle, stock acquisition or disposition agreement, or other agreement (whether written or oral, binding or non-binding) in connection with or relating to any Acquisition Proposal with respect to the Company, or (e) solicit proxies or initiate a shareholder vote with respect to an Acquisition Proposal with respect to the Company or otherwise knowingly facilitate any effort or attempt to make or implement an Acquisition Proposal with respect to the Company, except in each case to notify a person that has made or, to the knowledge of the Trustees, is making any inquiries with respect to, or is considering making, an Acquisition Proposal, of the existence of the provisions of this Section 5. Notwithstanding the immediately preceding sentence, and subject to Section 2 hereof, in the event the Company is engaging in discussions or negotiations with a person making an Acquisition Proposal in accordance with Section 6.11 of the Merger Agreement with respect to such Acquisition Proposal, the Trustees and their agents and representatives (including, without limitation, any investment banker, attorney or accountant retained by the Trustees on behalf of the Trust) shall be entitled to engage in any discussions or negotiations that the Company is permitted to engage in pursuant to Section 6.11 of the Merger Agreement with respect to such Acquisition Proposal.

Annex D — Opinion of J.P. Morgan Securities LLC

November 24, 2024

The Board of Directors
Bremer Financial Corporation
380 Saint Peter Street
Suite 500
Saint Paul, MN 55102

Members of the Board of Directors:

You have requested our opinion as to the fairness, from a financial point of view, to the holders of Class A common stock, no par value (the “Class A Common Stock”), and Class B common stock, no par value (the “Class B Common Stock” and, collectively with the Class A Common Stock, the “Company Common Stock”), of Bremer Financial Corporation (the “Company”) of the consideration to be paid to such holders in the proposed merger (the “Transaction”) of the Company with a wholly-owned subsidiary of Old National Bancorp (the “Acquiror”). Pursuant to the Agreement and Plan of Merger (the “Agreement”), among the Company, the Acquiror and its subsidiary, ONB Merger Sub, Inc. (“Merger Sub”), the Company will become a wholly-owned subsidiary of the Acquiror, and each outstanding share of Company Common Stock, other than shares of Company Common Stock held in treasury or owned by the Company, Acquiror or their respective affiliates (in each case other than shares held (i) in a fiduciary or agency capacity that are beneficially owned by third parties or (ii) directly or indirectly as a result of debts previously contracted) and Dissenting Shares (as defined in the Agreement), will be converted into the right to receive consideration per share equal to $26.22 in cash without interest (the “Cash Consideration”) and 4.182 shares (the “Stock Consideration”, and, together with the Cash Consideration, the “Consideration”) of the Acquiror’s common stock, no par value (the “Acquiror Common Stock”).

In connection with preparing our opinion, we have (i) reviewed a draft dated November 24, 2024 of the Agreement; (ii) reviewed certain publicly available business and financial information concerning the Company and the Acquiror and the industries in which they operate; (iii) compared the financial and operating performance of the Company and the Acquiror with publicly available information concerning certain other companies we deemed relevant and reviewed the current and historical market prices of the Acquiror Common Stock and certain publicly traded securities of such other companies; (iv) reviewed certain internal financial analyses and forecasts prepared by the management of the Company relating to the business of the Company, certain financial analyses and forecasts relating to the business of the Acquiror, which were approved by the Company for use in connection with our opinion, as well as the estimated amount and timing of the cost savings and related expenses and synergies expected to result from the Transaction (the “Synergies”); and (v) performed such other financial studies and analyses and considered such other information as we deemed appropriate for the purposes of this opinion.

In addition, we have held discussions with certain members of the management of the Company and the Acquiror with respect to certain aspects of the Transaction, and the past and current business operations of the Company and the Acquiror, the financial condition and future prospects and operations of the Company and the Acquiror, the effects of the Transaction on the financial condition and future prospects of the Company and the Acquiror, and certain other matters we believed necessary or appropriate to our inquiry.

In giving our opinion, we have relied upon and assumed the accuracy and completeness of all information that was publicly available or was furnished to or discussed with us by the Company and the Acquiror or otherwise reviewed by or for us. We have not independently verified any such information or its accuracy or completeness and, pursuant to our engagement letter with the Company, we did not assume any obligation to undertake any such independent verification. We have not conducted or been provided with any valuation or appraisal of any assets, liabilities or allowances for loan and lease losses, nor have we evaluated the solvency of the Company, the Acquiror or Merger Sub under any state or federal laws relating

D-1

TABLE OF CONTENTS

to bankruptcy, insolvency or similar matters. We are not experts in evaluating the adequacy of allowances for loan and lease losses of the Company or the Acquiror with respect to their loan and lease portfolios and, accordingly, we have not made an independent evaluation thereof, and we have assumed, with your consent, that the respective allowances for loan and lease losses for both the Company and the Acquiror, respectively, are adequate to cover such losses and will be adequate on a pro forma basis for the combined entity. In relying on financial analyses and forecasts provided to us or derived therefrom, including the Synergies, we have assumed that they have been reasonably prepared based on assumptions reflecting the best currently available estimates and judgments by management as to the expected future results of operations and financial condition of the Company and the Acquiror to which such analyses or forecasts relate. We express no view as to such analyses or forecasts (including the Synergies) or the assumptions on which they were based. In addition, we have assumed, with your consent, that the Acquiror’s proposed issuance of approximately $400 million of additional equity securities to certain investors will be consummated on the terms and conditions and in the time frame described by management of the Company. We have also assumed that the Transaction and the other transactions contemplated by the Agreement will qualify as a tax-free reorganization for United States federal income tax purposes, and will be consummated as described in the Agreement, and that the definitive Agreement will not differ in any material respects from the draft thereof furnished to us. We have also assumed that the representations and warranties made by the Company, the Acquiror and Merger Sub in the Agreement and the related agreements are and will be true and correct in all respects material to our analysis. We are not legal, regulatory or tax experts and have relied on the assessments made by advisors to the Company with respect to such issues. We have further assumed that all material governmental, regulatory or other consents and approvals necessary for the consummation of the Transaction will be obtained without any adverse effect on the Company or the Acquiror or on the contemplated benefits of the Transaction.

Our opinion is necessarily based on economic, market and other conditions as in effect on, and the information made available to us as of, the date hereof. It should be understood that subsequent developments may affect this opinion and that we do not have any obligation to update, revise, or reaffirm this opinion. Our opinion is limited to the fairness, from a financial point of view, of the Consideration to be paid to the holders of the Company Common Stock in the proposed Transaction and we express no opinion as to (i) the fairness of any consideration to be paid in connection with the Transaction to the holders of any other class of securities, creditors or other constituencies of the Company (ii) the allocation of the aggregate Consideration to be paid to all holders of Company Common Stock between the holders of Class A Common Stock and Class B Common Stock, or the relative fairness of the Consideration to the holders of any shares of the Company Common Stock, or (iii) as to the underlying decision by the Company to engage in the Transaction. We also do not express any opinion as to the Company Voting Agreement (as defined in the Agreement) or any voting, governance or other rights of the Trust (as defined in the Agreement), whether pursuant thereto or otherwise (and have not taken any such rights into account in our analysis). Furthermore, we express no opinion with respect to the amount or nature of any compensation to any officers, directors, or employees of any party to the Transaction, or any class of such persons relative to the Consideration to be paid to the holders of the Company Common Stock in the Transaction or with respect to the fairness of any such compensation. We are expressing no opinion herein as to the price at which the Acquiror Common Stock will trade at any future time.

We have acted as financial advisor to the Company with respect to the proposed Transaction and will receive a fee from the Company for our services, a substantial portion of which will become payable only if the proposed Transaction is consummated. In addition, the Company has agreed to indemnify us for certain liabilities arising out of our engagement. Please be advised that during the two years preceding the date of this letter, neither we nor our affiliates have had any other material financial advisory or other material commercial or investment banking relationships with the Company, the Company’s 85.96% shareholder (the Otto Bremer Trust) or the Acquiror. In addition, we and our affiliates hold, on a proprietary basis, less than 1% of the outstanding common stock of the Acquiror. In the ordinary course of our businesses, we and our affiliates may actively trade the debt and equity securities or financial instruments (including derivatives, bank loans or other obligations) of the Company or the Acquiror for our own account or for the accounts of customers and, accordingly, we may at any time hold long or short positions in such securities or other financial instruments.

TABLE OF CONTENTS

On the basis of and subject to the foregoing, it is our opinion as of the date hereof that the Consideration to be paid to the holders of the Company Common Stock in the proposed Transaction is fair, from a financial point of view, to such holders.

The issuance of this opinion has been approved by a fairness opinion committee of J.P. Morgan Securities LLC. This letter is provided to the Board of Directors of the Company (in its capacity as such) in connection with and for the purposes of its evaluation of the Transaction. This opinion does not constitute a recommendation to any shareholder of the Company as to how such shareholder should vote with respect to the Transaction or any other matter. This opinion may not be disclosed, referred to, or communicated (in whole or in part) to any third party for any purpose whatsoever except with our prior written approval. This opinion may be reproduced in full in any proxy or information statement mailed to shareholders of the Company but may not otherwise be disclosed publicly in any manner without our prior written approval.

Very truly yours,

J.P. MORGAN SECURITIES LLC

Annex E — Sections 302A.471 and 302A.473 of the Minnesota Business Corporation Act

302A.471 RIGHTS OF DISSENTING SHAREHOLDERS.

Subdivision 1. Actions creating rights. A shareholder of a corporation may dissent from, and obtain payment for the fair value of the shareholder’s shares in the event of, any of the following corporate actions:

(a) unless otherwise provided in the articles, an amendment of the articles that materially and adversely affects the rights or preferences of the shares of the dissenting shareholder in that it:

(1) alters or abolishes a preferential right of the shares;

(2) creates, alters, or abolishes a right in respect of the redemption of the shares, including a provision respecting a sinking fund for the redemption or repurchase of the shares;

(3) alters or abolishes a preemptive right of the holder of the shares to acquire shares, securities other than shares, or rights to purchase shares or securities other than shares;

(4) excludes or limits the right of a shareholder to vote on a matter, or to cumulate votes, except as the right may be excluded or limited through the authorization or issuance of securities of an existing or new class or series with similar or different voting rights; except that an amendment to the articles of an issuing public corporation that provides that section 302A.671 does not apply to a control share acquisition does not give rise to the right to obtain payment under this section; or

(5) eliminates the right to obtain payment under this subdivision;

(b) a sale, lease, transfer, or other disposition of property and assets of the corporation that requires shareholder approval under section 302A.661, subdivision 2, but not including a disposition in dissolution described in section 302A.725, subdivision 2, or a disposition pursuant to an order of a court, or a disposition for cash on terms requiring that all or substantially all of the net proceeds of disposition be distributed to the shareholders in accordance with their respective interests within one year after the date of disposition;

(c) a plan of merger, whether under this chapter or under chapter 322C, to which the corporation is a constituent organization, except as provided in subdivision 3, and except for a plan of merger adopted under section 302A.626;

(d) a plan of exchange, whether under this chapter or under chapter 322C, to which the corporation is a party as the corporation whose shares will be acquired by the acquiring organization, except as provided in subdivision 3;

(e) a plan of conversion is adopted by the corporation and becomes effective;

(f) an amendment of the articles in connection with a combination of a class or series under section 302A.402 that reduces the number of shares of the class or series owned by the shareholder to a fraction of a share if the corporation exercises its right to repurchase the fractional share so created under section 302A.423; or

(g) any other corporate action taken pursuant to a shareholder vote with respect to which the articles, the bylaws, or a resolution approved by the board directs that dissenting shareholders may obtain payment for their shares.

Subd. 2. Beneficial owners.

(a) A shareholder shall not assert dissenters’ rights as to less than all of the shares registered in the name of the shareholder, unless the shareholder dissents with respect to all the shares that are beneficially owned by another person but registered in the name of the shareholder and discloses the name and address of each beneficial owner on whose behalf the shareholder dissents. In that event, the rights of the dissenter shall be determined as if the shares as to which the shareholder has dissented and the other shares were registered in the names of different shareholders.

(b) A beneficial owner of shares who is not the shareholder may assert dissenters’ rights with respect to shares held on behalf of the beneficial owner, and shall be treated as a dissenting shareholder under the terms

E-1

TABLE OF CONTENTS

of this section and section 302A.473, if the beneficial owner submits to the corporation at the time of or before the assertion of the rights a written consent of the shareholder.

Subd. 3. Rights not to apply.

(a) Unless the articles, the bylaws, or a resolution approved by the board otherwise provide, the right to obtain payment under this section does not apply to a shareholder of (1) the surviving corporation in a merger with respect to shares of the shareholder that are not entitled to be voted on the merger and are not canceled or exchanged in the merger or (2) the corporation whose shares will be acquired by the acquiring organization in a plan of exchange with respect to shares of the shareholder that are not entitled to be voted on the plan of exchange and are not exchanged in the plan of exchange.

(b) If a date is fixed according to section 302A.445, subdivision 1, for the determination of shareholders entitled to receive notice of and to vote on an action described in subdivision 1, only shareholders as of the date fixed, and beneficial owners as of the date fixed who hold through shareholders, as provided in subdivision 2, may exercise dissenters’ rights.

(c) Notwithstanding subdivision 1, the right to obtain payment under this section, other than in connection with a plan of merger adopted under section 302A.613, subdivision 4, or 302A.621, is limited in accordance with the following provisions:

(1) The right to obtain payment under this section is not available for the holders of shares of any class or series of shares that is listed on the New York Stock Exchange, NYSE MKT LLC, the Nasdaq Global Market, the NASDAQ Global Select Market, the Nasdaq Capital Market, or any successor to any such market.

(2) The applicability of clause (1) is determined as of:

(i) the record date fixed to determine the shareholders entitled to receive notice of, and to vote at, the meeting of shareholders to act upon the corporate action described in subdivision 1; or

(ii) the day before the effective date of corporate action described in subdivision 1 if there is no meeting of shareholders.

(3) Clause (1) is not applicable, and the right to obtain payment under this section is available pursuant to subdivision 1, for the holders of any class or series of shares who are required by the terms of the corporate action described in subdivision 1 to accept for such shares anything other than shares, or cash in lieu of fractional shares, of any class or any series of shares of a domestic or foreign corporation, or any other ownership interest of any other organization, that satisfies the standards set forth in clause (1) at the time the corporate action becomes effective.

Subd. 4. Other rights.

The shareholders of a corporation who have a right under this section to obtain payment for their shares, or who would have the right to obtain payment for their shares absent the exception set forth in paragraph (c) of subdivision 3, do not have a right at law or in equity to have a corporate action described in subdivision 1 set aside or rescinded, except when the corporate action is fraudulent with regard to the complaining shareholder or the corporation.

302A.473 PROCEDURES FOR ASSERTING DISSENTERS’ RIGHTS.

Subdivision 1. Definitions.

(a) For purposes of this section, the terms defined in this subdivision have the meanings given them.

(d) “Interest” means interest commencing five days after the effective date of the corporate action referred to in section 302A.471, subdivision 1, up to and including the date of payment, calculated at the rate provided in section 549.09, subdivision 1, paragraph (c), clause (1).

Subd. 2. Notice of action.

(a) If a corporation calls a shareholder meeting at which any action described in section 302A.471, subdivision 1 is to be voted upon, the notice of the meeting shall inform each shareholder of the right to dissent and shall include a copy of section 302A.471 and this section and a brief description of the procedure to be followed under these sections.

(b) In connection with a qualified offer as described in section 302A.613, subdivision 4, the constituent corporation subject to the offer may, but is not required to, send to all shareholders a written notice informing each shareholder of the right to dissent and must include a copy of this section and section 302A.471 and a brief description of the procedure to be followed under these sections. To be effective, the notice must be sent as promptly as practicable at or following the commencement of the offer, but in any event at least ten days before the consummation of the offer.

Subd. 3. Notice of dissent.

If the proposed action must be approved by the shareholders and the corporation holds a shareholder meeting, a shareholder who is entitled to dissent under section 302A.471 and who wishes to exercise dissenters’ rights must file with the corporation before the vote on the proposed action a written notice of intent to demand the fair value of the shares owned by the shareholder and must not vote the shares in favor of the proposed action. If the proposed action is to be effected pursuant to section 302A.613, subdivision 4, and the corporation has elected to send a notice of action in accordance with subdivision 2, paragraph (b), a shareholder who is entitled to dissent under section 302A.471 and who wishes to exercise dissenters’ rights must not tender the shares owned by the shareholder in response to the offer and must file with the corporation a written notice of intent to demand the fair value of the shares owned by the shareholder. Written notice must be filed with the corporation before the consummation of the offer.

Subd. 4. Notice of procedure; deposit of shares.

(a) After the proposed action has been approved by the board and, if necessary, the shareholders, the corporation shall send (i) in any case where subdivision 3 is applicable, to all shareholders who have complied with subdivision 3, (ii) in any case where a written action of shareholders gave effect to the action creating the right to obtain payment under section 302A.471, to all shareholders who did not sign or consent to a written action that gave effect to the action creating the right to obtain payment under section 302A.471, and (iii) in any other case, to all shareholders entitled to dissent, a notice that contains:

(1) the address to which a demand for payment and certificates of certificated shares must be sent in order to obtain payment and the date by which they must be received;

(2) any restrictions on transfer of uncertificated shares that will apply after the demand for payment is received;

(3) a form to be used to certify the date on which the shareholder, or the beneficial owner on whose behalf the shareholder dissents, acquired the shares or an interest in them and to demand payment; and

E-3

TABLE OF CONTENTS

(4) a copy of section 302A.471 and this section and a brief description of the procedures to be followed under these sections.

(b) In order to receive the fair value of the shares, a dissenting shareholder must demand payment and deposit certificated shares or comply with any restrictions on transfer of uncertificated shares within 30 days after the notice required by paragraph (a) was given, but the dissenter retains all other rights of a shareholder until the proposed action takes effect.

Subd. 5. Payment; return of shares.

(a) After the corporate action takes effect, or after the corporation receives a valid demand for payment, whichever is later, the corporation shall remit to each dissenting shareholder who has complied with subdivisions 3 and 4 the amount the corporation estimates to be the fair value of the shares, plus interest, accompanied by:

(1) the corporation’s closing balance sheet and statement of income for a fiscal year ending not more than 16 months before the effective date of the corporate action, together with the latest available interim financial statements;

(2) an estimate by the corporation of the fair value of the shares and a brief description of the method used to reach the estimate; and

(3) a copy of section 302A.471 and this section, and a brief description of the procedure to be followed in demanding supplemental payment.

(b) The corporation may withhold the remittance described in paragraph (a) from a person who was not a shareholder on the date the action dissented from was first announced to the public or who is dissenting on behalf of a person who was not a beneficial owner on that date. If the dissenter has complied with subdivisions 3 and 4, the corporation shall forward to the dissenter the materials described in paragraph (a), a statement of the reason for withholding the remittance, and an offer to pay to the dissenter the amount listed in the materials if the dissenter agrees to accept that amount in full satisfaction. The dissenter may decline the offer and demand payment under subdivision 6. Failure to do so entitles the dissenter only to the amount offered. If the dissenter makes demand, subdivisions 7 and 8 apply.

(c) If the corporation fails to remit payment within 60 days of the deposit of certificates or the imposition of transfer restrictions on uncertificated shares, it shall return all deposited certificates and cancel all transfer restrictions. However, the corporation may again give notice under subdivision 4 and require deposit or restrict transfer at a later time.

Subd. 6. Supplemental payment; demand.

If a dissenter believes that the amount remitted under subdivision 5 is less than the fair value of the shares plus interest, the dissenter may give written notice to the corporation of the dissenter’s own estimate of the fair value of the shares, plus interest, within 30 days after the corporation mails the remittance under subdivision 5, and demand payment of the difference. Otherwise, a dissenter is entitled only to the amount remitted by the corporation.

Subd. 7. Petition; determination.

If the corporation receives a demand under subdivision 6, it shall, within 60 days after receiving the demand, either pay to the dissenter the amount demanded or agreed to by the dissenter after discussion with the corporation or file in court a petition requesting that the court determine the fair value of the shares, plus interest. The petition shall be filed in the county in which the registered office of the corporation is located, except that a surviving foreign corporation that receives a demand relating to the shares of a constituent domestic corporation shall file the petition in the county in this state in which the last registered office of the constituent corporation was located. The petition shall name as parties all dissenters who have demanded payment under subdivision 6 and who have not reached agreement with the corporation. The corporation shall, after filing the petition, serve all parties with a summons and copy of the petition under the Rules of Civil Procedure. Nonresidents of this state may be served by registered or certified mail or by publication as provided by law. Except as otherwise provided, the Rules of Civil Procedure apply to this

TABLE OF CONTENTS

proceeding. The jurisdiction of the court is plenary and exclusive. The court may appoint appraisers, with powers and authorities the court deems proper, to receive evidence on and recommend the amount of the fair value of the shares. The court shall determine whether the shareholder or shareholders in question have fully complied with the requirements of this section, and shall determine the fair value of the shares, taking into account any and all factors the court finds relevant, computed by any method or combination of methods that the court, in its discretion, sees fit to use, whether or not used by the corporation or by a dissenter. The fair value of the shares as determined by the court is binding on all shareholders, wherever located. A dissenter is entitled to judgment in cash for the amount by which the fair value of the shares as determined by the court, plus interest, exceeds the amount, if any, remitted under subdivision 5, but shall not be liable to the corporation for the amount, if any, by which the amount, if any, remitted to the dissenter under subdivision 5 exceeds the fair value of the shares as determined by the court, plus interest.

Subd. 8. Costs; fees; expenses.

(a) The court shall determine the costs and expenses of a proceeding under subdivision 7, including the reasonable expenses and compensation of any appraisers appointed by the court, and shall assess those costs and expenses against the corporation, except that the court may assess part or all of those costs and expenses against a dissenter whose action in demanding payment under subdivision 6 is found to be arbitrary, vexatious, or not in good faith.

(b) If the court finds that the corporation has failed to comply substantially with this section, the court may assess all fees and expenses of any experts or attorneys as the court deems equitable. These fees and expenses may also be assessed against a person who has acted arbitrarily, vexatiously, or not in good faith in bringing the proceeding, and may be awarded to a party injured by those actions.

(c) The court may award, in its discretion, fees and expenses to an attorney for the dissenters out of the amount awarded to the dissenters, if any.
