Merger Proposal — Your Vote Is Important

On November 30, 2022, Byline Bancorp, Inc., which we refer to as Byline, and Inland Bancorp, Inc., which we refer to as Inland, and Butterfield Acquisition Corporation, a wholly owned subsidiary of Byline (which we refer to as “merger sub”), entered into an Agreement and Plan of Merger (which we refer to as the merger agreement), pursuant to which Byline has agreed to acquire Inland. Upon the terms and subject to the conditions of the merger agreement, merger sub will be merged with and into Inland, with Inland as the surviving corporation and wholly owned subsidiary of Byline (which we refer to as the merger). Immediately following the merger, Inland will be merged with and into Byline, with Byline as the surviving corporation (which we refer to as the parent merger), and immediately following the parent merger, Inland Bank and Trust (which we refer to as Inland Bank), an Illinois state chartered bank and wholly owned subsidiary of Inland, will merge with and into Byline Bank, an Illinois chartered bank and wholly owned subsidiary of Byline, with Byline Bank as the resulting bank as a wholly owned subsidiary of Byline (which we refer to as the bank merger).

Stockholders of Inland will receive the following for each share of Inland common stock, par value $1.00 per share (which we refer to as Inland common stock), they own (other than shares, if any, owned by Inland or Byline or any shares as to which statutory appraisal rights have been properly exercised and perfected), which we refer to as the “merger consideration”: (i) the number of shares of Byline’s common stock, par value $0.01 per share, equal to the quotient obtained by dividing (A) 6,389,351 by (B) the number of shares of Inland common stock issued and outstanding immediately prior to the effective time of the merger (which we refer to as the “effective time”) (the “Exchange Ratio”); and (ii) a cash payment in the amount equal to the quotient obtained by dividing (A) $22,867,150.20 by (B) the number of shares of Inland common stock issued and outstanding immediately prior to the effective time (the “Cash Consideration”), subject to adjustment in the event the dollar amount of Inland’s tangible common equity at closing is above or below certain thresholds set forth in the merger agreement; provided, however, that in the event Inland has less than 33,628,162 shares of common stock issued and outstanding at closing, then (1) the Exchange Ratio will be equal to 0.19 share of Byline common stock and (2) the Cash Consideration will be equal to $0.68, for each share of Inland common stock issued and outstanding at closing. Inland stock options will be cancelled and the holder thereof will be entitled to a cash payment pursuant to the terms of the merger agreement.

Byline common stock currently trades on the New York Stock Exchange, or NYSE, under the symbol “BY”. Inland common stock is privately held and not traded in any public market. The shares of Byline common stock issued pursuant to the merger will be registered under the Securities Act of 1933, as amended, and will trade on the NYSE at closing.

The value of the merger consideration will fluctuate as the market price of Byline common stock fluctuates before the completion of the merger. Thus, the value of the merger consideration will not be known at the time of the special meeting of Inland stockholders called for the purpose of voting on the merger agreement and the market price of Byline common stock at the time of completion of the merger may be more or less than the current price of Byline common stock or the price of Byline common stock at the time of the special meeting.

Based on the closing price of Byline common stock as reported on the NYSE of $22.21 as of November 29, 2022, the trading day prior to the day on which the public announcement of the merger was made, and assuming there are no adjustments pursuant to the merger agreement, the implied value of the merger consideration was approximately $4.90 per share of Inland common stock and the implied aggregate transaction value on a fully diluted basis was approximately $165.4 million.

TABLE OF CONTENTS

approximately $4.41 per share of Inland common stock and the implied aggregate transaction value on a fully diluted basis was approximately $148.8 million. We urge you to obtain current market quotations for shares of Byline common stock.

We cannot complete the merger unless we obtain the necessary approval from the stockholders of Inland as described in the attached proxy statement/prospectus. Accordingly, Inland will hold a special meeting of its stockholders in connection with the merger at 2:00 p.m., local time, on Tuesday, May 30, 2023, at The Legacy Room, 2901 Butterfield Road, Oak Brook, Illinois 60523, which we refer to as the special meeting. Inland stockholders will be asked to vote to adopt the merger agreement, which we refer to as the merger proposal, and to approve one or more adjournments of the special meeting, if necessary or appropriate, as determined by Inland, including adjournments to permit further solicitation of proxies in favor of the merger proposal, which we refer to as the adjournment proposal. Approval of the merger proposal requires the affirmative vote of holders of two-thirds of the outstanding shares of common stock of Inland. The adjournment proposal will be approved if a majority of the shares having voting power present in person or represented by proxy at the special meeting are voted in favor of the adjournment proposal.

Inland’s board of directors has unanimously approved the merger agreement, has unanimously determined that the merger agreement and the transactions contemplated thereby, including the merger, are advisable and in the best interests of Inland and its stockholders, and unanimously recommends that Inland stockholders vote “FOR” the merger proposal and “FOR” the adjournment proposal.

YOUR VOTE IS VERY IMPORTANT. We cannot complete the merger unless Inland’s stockholders approve the merger proposal.

Regardless of whether you plan to attend the special meeting, please vote as soon as possible. If you hold stock in your name as a stockholder of record of Inland, please submit a proxy to have your shares voted as promptly as possible by either: (1) dialing the telephone number shown on your proxy card and following the instructions to vote by phone; (2) logging onto the website shown on your proxy card and following the instructions to vote online; or (3) signing and returning the accompanying proxy card in the enclosed postage-paid return envelope. You may also cast your vote in person at the special meeting. If you hold your stock in “street name” through a bank or broker, please follow the instructions on the voting instruction card furnished by the record holder.

You should read this entire proxy statement/prospectus carefully because it contains important information about the merger. In particular, you should read the information under the section entitled “Risk Factors” beginning on page 27.

2. a proposal to adjourn the special meeting, if necessary or appropriate, as determined by Inland, to solicit additional proxies in favor of the merger proposal (which we refer to as the adjournment proposal).

Approval of the merger proposal requires the affirmative vote of holders of two-thirds of the outstanding shares of Inland common stock. The adjournment proposal will be approved if a majority of the shares having voting power present in person or represented by proxy at the special meeting are voted in favor of the adjournment proposal.

Your vote is very important. We cannot complete the merger unless Inland’s stockholders approve the merger proposal. Regardless of whether you plan to attend the special meeting, please vote as soon as possible.

TABLE OF CONTENTS

proxy statement/prospectus, holders of Inland common stock who do not vote in favor of the merger proposal will have the right to seek appraisal of the fair value of their shares of Inland common stock as determined under the MGCL if the merger is completed, but only if they submit a written demand for such an appraisal prior to the vote on the merger proposal and comply with the other Maryland law procedures explained in the enclosed proxy statement/prospectus. Holders of Inland common stock who do not vote in favor of the merger proposal and who submit a written demand for such an appraisal prior to the vote on the merger proposal and comply with the other Maryland law procedures will not receive the merger consideration, but instead will have their Inland common stock converted into the right to receive payment of such appraised value in accordance with Maryland law procedures as explained in the enclosed proxy statement/prospectus.

QUESTIONS AND ANSWERS

The following are some questions that you may have regarding the proposals being considered at the special meeting of stockholders of Inland Bancorp, Inc. (which we refer to as the special meeting). You should carefully read the remainder of this proxy statement/prospectus because the information in this section may not provide all the information that might be important to you in determining how to vote. Additional important information is also contained in the appendices to, and the documents incorporated by reference in, this proxy statement/prospectus. See “Incorporation of Certain Documents by Reference” beginning on page 91.

What is the Merger?

Byline Bancorp. Inc., a Delaware corporation (which we refer to as Byline), Butterfield Acquisition Corporation (which we refer to as merger sub) and Inland Bancorp, Inc., a Maryland corporation (which we refer to as Inland), have entered into an Agreement and Plan of Merger, dated as of November 30, 2022, as such agreement may be amended from time to time (which we refer to as the merger agreement). The merger agreement provides that, upon the terms and subject to the conditions set forth in the merger agreement, merger sub will be merged with and into Inland, with Inland as the surviving corporation and wholly owned subsidiary of Byline (which we refer to as the merger). Immediately following the merger, Inland will be merged with and into Byline, with Byline as the surviving corporation (which we refer to as the parent merger). A copy of the merger agreement is attached to this proxy statement/ prospectus as Appendix A. We refer to the time at which the merger becomes effective as the effective time.

Immediately following the parent merger, Inland Bank and Trust (which we refer to as Inland Bank), an Illinois state chartered bank and wholly owned subsidiary of Inland, will merge with and into Byline Bank, an Illinois chartered bank and wholly owned subsidiary of Byline, with Byline Bank as the resulting bank as a wholly owned subsidiary of Byline (which we refer to as the bank merger). Upon completion of the bank merger, Inland Bank’s banking offices will become banking offices of Byline Bank.

Why am I receiving this proxy statement/prospectus?

The board of directors of Inland (which we refer to as the Inland board) is using this proxy statement/prospectus to solicit proxies from Inland’s stockholders in connection with the merger.

In order to complete the merger, Inland’s stockholders must approve the merger agreement. Inland stockholders are also being asked to approve one or more adjournments of the special meeting, if necessary or appropriate, as determined by Inland, including adjournments to permit further solicitation of proxies in favor of the merger agreement. For additional information regarding the proposals to be presented to Inland stockholders, refer to the section entitled “Inland Proposals”. Inland will hold a special meeting to consider and vote on these proposals. This proxy statement/prospectus contains important information about the merger and the special meeting, and you should read it carefully and in its entirety. The enclosed voting materials allow you to vote your shares of Inland common stock, par value $1.00 per share (which we refer to as Inland common stock), without attending the special meeting in person.

We encourage you to submit a proxy to vote your shares of Inland common stock as promptly as possible so that your shares may be represented and voted at the special meeting.

This proxy statement/prospectus is also a prospectus with respect to the offering of shares of Byline common stock, par value $0.01 per share (which we refer to as Byline common stock) to be issued in connection with the merger.

What will Inland stockholders receive in the merger?

If the merger is completed and assuming the consideration is not adjusted pursuant to the terms of the merger agreement as described in this proxy statement/prospectus, each share of Inland common stock outstanding immediately prior to the effective time, other than shares, if any, owned by Inland or

TABLE OF CONTENTS

Byline or as to which statutory appraisal rights have been properly exercised and perfected, will be converted into the right to receive the following (which we refer to as the per share merger consideration):

•

the number of shares of Byline common stock equal to the quotient obtained by dividing (i) 6,389,351 by (ii) the number of shares of Inland common stock issued and outstanding immediately prior to the effective time (which we refer to as the exchange ratio); and

•

a cash payment in the amount equal to the quotient obtained by dividing (i) $22,867,150.20 by (ii) the number of shares of Inland common stock issued and outstanding immediately prior to the effective time (which we refer to as the cash consideration), subject to adjustment in the event the dollar amount of Inland’s tangible common equity at closing is above or below certain thresholds set forth in the merger agreement.

Provided, however, that in the event Inland has less than 33,628,162 shares of common stock issued and outstanding at closing, then (1) the exchange ratio will be equal to 0.19 share of Byline common stock and (2) the cash consideration will be equal to $0.68, for each share of Inland common stock issued and outstanding at closing. Inland stock options will be cancelled and the holder thereof will be entitled to a cash payment pursuant to the terms of the merger agreement.

The merger consideration may be adjusted only under certain limited circumstances as set forth in the merger agreement and as described in the answer to the next question. Based on the closing price of Byline common stock as reported on the NYSE of $22.21 as of November 29, 2022, the trading day prior to the day on which the public announcement of the merger was made, and assuming there are no adjustments pursuant to the merger agreement, the merger consideration represents approximately a 14% cash and 86% stock mix. Inland stockholders also will receive cash in lieu of any fractional shares of Byline common stock that would otherwise be issuable in connection with the merger. For more information on the potential adjustments to the merger consideration and cash in lieu of fractional shares, see “Description of the Merger Agreement — Merger Consideration”.

Is the merger consideration subject to adjustment?

Yes, the merger consideration may be adjusted only under certain limited circumstances as set forth in the merger agreement.

In the event that Inland’s tangible common equity (as calculated pursuant to merger agreement and set forth on Inland’s final closing balance sheet) is less than $135.350 million, then the aggregate cash consideration will be reduced on a dollar-for-dollar basis by the amount of such shortfall.

If Inland’s tangible common equity at closing is greater than $141.350 million, then the aggregate cash consideration will be increased on a dollar-for-dollar basis by the amount that is greater than $141.350 million; provided, that, the amount of such increase will not exceed an amount that would result in either Inland’s counsel or Byline’s counsel being unable to deliver its respective tax opinion under the merger agreement, and the aggregate cash consideration will only be increased to the maximum amount that would allow such opinions to be delivered, with the remaining portion of such increase to be paid in shares of Byline common stock based on the Byline closing price.

For more information on the potential adjustments to the merger consideration, see “Description of the Merger Agreement — Merger Consideration”.

Will the merger consideration be adjusted based on the trading price of Byline’s common stock prior to closing?

No, the merger consideration will not be adjusted solely due to changes in the trading price of Byline common stock prior to the closing of the merger.

What is the value of the merger consideration?

TABLE OF CONTENTS

completion of the merger may be more or less than the current price of Byline common stock or the price of Byline common stock at the time of the special meeting.

Based on the closing price of Byline common stock as reported on the NYSE of $19.63 as of April 24, 2023, the last practicable date before the date of this proxy statement/prospectus, and assuming there are no adjustments pursuant to the merger agreement, the implied value of the merger consideration was approximately $4.41 per share of Inland common stock and the implied aggregate transaction value on a fully diluted basis was approximately $148.8 million. We urge you to obtain current market quotations for shares of Byline common stock.

How will the stock options of Inland be treated as a result of the merger?

Each Inland stock option that is outstanding immediately prior to the effective time will be cancelled in exchange for a cash payment equal to the product of (A) the difference between (i) the sum of (x) the product of the exchange ratio multiplied by the volume weighted average price of one share of Byline common stock as reported on the NYSE for the five (5) business days ending on the business day immediately prior to the closing date (which we refer to as the Byline closing price) plus (y) the cash consideration, less (ii) the exercise price per share of Inland common stock under such stock option, multiplied by (B) the number of shares of Inland common stock covered by such stock option (each an “Option Payment”). In order to receive the Option Payment, each Inland stock option holder must execute and submit to Inland an option termination agreement which includes a full release of any claims related to such options against Inland and Inland Bank.

When will the merger be completed?

Byline and Inland are working to complete the merger as soon as practicable. Subject to the satisfaction or waiver of the closing conditions described under the section entitled “Description of the Merger Agreement — Conditions to Consummation of the Merger,” including the approval of the merger agreement by Inland stockholders, the parties are seeking to consummate the merger by the second quarter of 2023. However, it is possible that factors outside the control of Byline and Inland could result in the merger being completed at a later time or not at all. There may be a substantial amount of time between the special meeting and the completion of the merger.

Who is entitled to vote?

Holders of record of shares of Inland common stock at the close of business on April 21, 2023, which is the date that the Inland board has fixed as the record date for the special meeting, are entitled to vote at the special meeting.

What constitutes a quorum?

A majority of the shares of Inland common stock entitled to vote, represented in person or by proxy, constitutes a quorum for transacting business at the special meeting. Proxies marked as abstaining on any matter to be acted upon by stockholders will be counted as represented at the meeting for purposes of determining the presence or absence of a quorum.

What and I being asked to vote on and why is this approval necessary?

Inland stockholders are being asked to vote on the following proposals:

a proposal to adopt the merger agreement, a copy of which is attached as Appendix A, which we refer to as the merger proposal; and

a proposal to adjourn the special meeting, if necessary or appropriate, as determined by Inland, to solicit additional proxies in favor of the merger proposal, which we refer to as the adjournment proposal.

TABLE OF CONTENTS

Inland stockholder approval is required to complete the merger. Inland will transact no business at the special meeting other than as listed above.

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

The Merger Proposal: Approval of the merger proposal requires the affirmative vote of holders of two-thirds of the outstanding shares of Inland common stock entitled to vote at the special meeting.

The Adjournment Proposal: The adjournment proposal requires the affirmative vote of a majority of the shares having voting power present in person or represented by proxy at a duly held meeting at which a quorum is present.

Are there any voting agreements with existing stockholders?

Yes. Daniel L. Goodwin, Inland’s Chairman and Chief Executive Officer and largest stockholder, in his capacity as a beneficial owner of shares of Inland common stock, has entered into a voting agreement with Byline pursuant to which Mr. Goodwin has agreed to vote all shares of Inland common stock that he beneficially owns and has the power to vote in favor of the merger proposal and any other matter that is required to be approved by the stockholders of Inland to facilitate the transactions contemplated by the merger agreement. Mr. Goodwin also agreed to vote against any proposal made in opposition to the approval of the merger or in competition with the merger agreement and against any other acquisition proposal. As of the close of business on the record date, Mr. Goodwin beneficially owned, in the aggregate, 24,922,465.50 shares of Inland common stock, allowing him to exercise approximately 74.11% of the voting power of Inland common stock.

What does the Inland Board of Directors recommend?

The Inland board unanimously recommends that Inland stockholders vote “FOR” the merger proposal and “FOR” the adjournment proposal.

What do I need to do now?

After carefully reading and considering the information contained in this proxy statement/prospectus, please vote your shares of Inland common stock as soon as possible so that such shares will be represented at the special meeting. Please follow the instructions set forth on the proxy card or on the voting instruction form provided by the record holder if your shares of Inland common stock are held in the name of your broker, bank or other nominee.

How do I vote?

If you are an Inland stockholder of record as of the close of business on the record date, you may submit your proxy before the special meeting by completing, signing, dating and returning the enclosed proxy card in the enclosed postage-paid envelope.

You may also cast your vote in person at the special meeting.

If your shares of Inland common stock are held in “street name,” through a broker, bank or other nominee, that institution will send you separate instructions describing the procedure for voting such shares. “Street name” stockholders who wish to vote at the meeting will need to obtain a proxy form from their broker, bank or other nominee.

How many votes do I have?

You are entitled to one vote for each share of Inland common stock that you owned as of the close of business on the record date. As of the close of business on the record date, there were approximately 33,628,162 outstanding shares of Inland common stock entitled to vote. As of that date, approximately 81.17% of such outstanding shares of Inland common stock were beneficially owned by the directors and executive officers of Inland and their affiliates.

TABLE OF CONTENTS

When and where is the special meeting?

The special meeting will be held at 2:00 p.m., local time, on Tuesday, May 30, 2023, at The Legacy Room 2901 Butterfield Road, Oak Brook, Illinois 60523. Subject to space availability, all Inland stockholders as of the close of business on the record date, or their duly appointed proxies, may attend the special meeting. Since seating may be limited, admission to the special meeting will be on a first-come, first-served basis. Registration and seating will begin at 1:30 p.m., local time.

If my shares are held in “street name” by a broker, bank or other nominee, will my broker, bank or other nominee vote my shares for me?

If your shares of Inland common stock are held in “street name” by a broker, bank or other nominee, you must provide the record holder of your shares with instructions on how to vote your shares. Please follow the voting instructions provided by your broker, bank or other nominee.

Please note that you may not vote shares held in “street name” by returning a proxy card directly to Inland or by voting in person at the special meeting unless you provide a “legal proxy,” which you must obtain from your broker, bank or other nominee.

Brokers who hold shares in “street name” for the beneficial owner of those shares typically have the authority to vote in their discretion on “routine” proposals when they have not received instructions from the beneficial owner. However, brokers are not allowed to exercise their voting discretion with respect to the approval of matters that are “non-routine” without specific instructions from the beneficial owner. Both proposals to be voted on at the special meeting are considered “non-routine” matters and, therefore, brokers, banks and other nominees do not have discretionary voting power on these matters.

If you are an Inland stockholder and you do not instruct your broker, bank or other nominee on how to vote your shares, then your broker, bank or other nominee may not vote your shares on either the merger proposal or the adjournment proposal.

•

For the merger proposal, shares not represented at the special meeting are still considered outstanding and, therefore, will have the same effect as a vote “AGAINST” the proposal. Approval of the merger proposal requires the affirmative vote of holders of two-thirds of the outstanding shares of Inland common stock entitled to vote at the special meeting. Therefore, the failure of a holder of shares of Inland common stock to provide its bank, broker or other nominee with voting instructions will have the same effect as a vote “AGAINST” the merger proposal.

•

The adjournment proposal requires the affirmative vote of a majority of the shares having voting power present in person or represented by proxy at a duly held meeting at which a quorum is present. Your bank, broker or other nominee does not have discretionary authority to vote your shares on the special meeting proposals without your instructions. Consequently, failure to provide instructions to your bank, broker or other nominee on how to vote will result in your shares not being counted as represented for purposes of establishing a quorum at the special meeting. Accordingly, such a failure would have an effect on the outcome of the vote if such failure prevents a quorum from being established.

What if I abstain or do not vote?

For purposes of the special meeting, an abstention occurs when a stockholder attends the special meeting, either in person or represented by proxy, but abstains from voting.

Abstentions will be counted as represented at the special meeting for purposes of determining the presence or absence of a quorum for all matters to be voted on at the special meeting.

For the merger proposal, if an Inland stockholder present in person at the special meeting abstains from voting, or responds by proxy with an “abstain” vote, it will have the same effect as a vote cast “AGAINST” the proposal. If an Inland stockholder is not present in person at the special meeting and does not respond by proxy, it will also have the same effect as a vote cast “AGAINST” the proposal.

The adjournment proposal requires the affirmative vote of the majority of the shares having voting power present in person or represented by proxy at a duly held meeting at which a quorum is present.

Accordingly, for purposes of the adjournment proposal, abstentions will affect the outcome as they will be counted as shares represented at the meeting, but not voted affirmatively in favor of the adjournment proposal.

What will happen if I return my proxy or voting instruction card without indicating how to vote?

If you hold your shares of Inland common stock in your name as a stockholder of record, and you sign and return your proxy card without indicating how to vote on any particular proposal, the shares of Inland common stock represented by your proxy will be voted “FOR” the merger proposal and “FOR” the adjournment proposal.

If you hold your shares of Inland common stock in “street name” through a broker, bank or other nominee and you do not give your broker, bank or other nominee instructions on how to vote, your broker, bank or other nominee will not be able to vote your shares of Inland common stock on either of the proposals at the special meeting and your shares of Inland common stock will not be represented at the special meeting. For the merger proposal, shares not represented at the special meeting are still considered outstanding and, therefore, will have the same effect as a vote “AGAINST” the proposal. For purposes of the adjournment proposal, shares not represented at the special meeting will not affect the outcome as they will not be deemed to be present at the meeting for purposes of determining the required majority vote.

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

Yes. If you hold your shares of Inland common stock in your name as a stockholder of record, you may change your vote at any time before your proxy is voted at the special meeting. You may do so in one of three ways:

•

first, by sending a notice of revocation stating that you would like to revoke your proxy;

•

second, by sending a completed proxy card bearing a later date than your original proxy card; or

•

third, by attending the special meeting and voting in person. Attendance at the special meeting will not in itself constitute the revocation of a proxy.

If you are an Inland stockholder of record and you choose to send a written notice of revocation or to mail a new proxy card, you must submit your notice of revocation or your new proxy to:

Inland Bancorp, Inc.
Attn: Peter Stickler
2805 Butterfield Road
Oak Brook, Illinois 60523
(877) 908-6555

Any proxy that you submitted may also be revoked by voting in person at the special meeting.

If your shares are held in “street name” through a broker, bank or other nominee and you have instructed your nominee how to vote your shares of Inland common stock, you must submit new voting instructions to your nominee. You should follow the instructions you receive from your broker, bank or other nominee in order to change or revoke your vote.

Do I need identification to attend the special meeting in person?

Yes. If you hold your shares of Inland common stock in your name as a stockholder of record and you wish to attend the special meeting and vote in person, please bring valid picture identification.

If your shares are held in “street name” through a broker, bank or other nominee, you may only vote in person at the special meeting if you have proof of ownership of your shares of Inland common stock as of the record date and obtain a valid legal proxy from your broker, bank or other nominee that is the stockholder of record of such shares and present such items at the special meeting. You must also bring valid picture identification.

TABLE OF CONTENTS

Are Inland stockholders entitled to appraisal rights?

Inland stockholders will be entitled to appraisal rights but only if they comply with the Maryland law procedures summarized in the section entitled “The Merger — Dissenters’ Rights”. The entirety of Sections 3-202 through 3-213 of the Maryland General Corporation Law, as amended (which we refer to as the MGCL), is provided on Appendix B to this proxy statement/prospectus. Upon consummation of the merger, any Inland stockholder who has perfected her, his or its appraisal rights will have the right to have a court in Maryland determine the value of each share of stock and to be paid the appraised value determined by the court, which could be more or less than the merger consideration.

What are the material U.S. federal income tax consequences of the merger to U.S. holders of shares of Inland common stock?

The merger and the parent merger (which together we refer to as the “integrated merger”) are intended to constitute a single integrated transaction that for federal income tax purposes will qualify as a reorganization within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended (which we refer to as the Code), and the obligation of Byline and Inland to complete the merger is conditioned upon the receipt of legal opinions from their respective counsel to that effect. However, neither Inland nor Byline has requested or received a ruling from the Internal Revenue Service that the integrated merger will qualify as a reorganization. If the integrated merger qualifies as a reorganization for U.S. federal income tax purposes, a U.S. holder of Inland common stock generally will recognize gain (but not loss) upon receipt of Byline common stock and cash (other than cash received in lieu of a fractional share of Byline common stock) in exchange for shares of Inland common stock pursuant to the merger in an amount equal to the lesser of (1) the amount of gain realized (i.e., the excess of the sum of the amount of cash and the fair market value of the Byline common stock received pursuant to the merger over such holder’s adjusted tax basis in the shares of Inland common stock surrendered in the exchange) and (2) the amount of cash received pursuant to the merger (excluding any cash received in lieu of a fractional share of Byline common stock). In addition, a U.S. holder of Inland common stock generally will recognize gain or loss with respect to the cash received in lieu of a fractional share of Byline common stock.

For a more detailed discussion of the material U.S. federal income tax consequences of the integrated merger, please see the section entitled “Material U.S. Federal Income Tax Consequences of the Integrated Merger”.

The tax consequences of the integrated merger to any particular stockholder will depend on that stockholder’s particular facts and circumstances. Accordingly, you are urged to consult your tax advisor to determine your tax consequences from the integrated merger.

What happens if the merger is not completed?

If the merger is not completed, Inland stockholders will not receive any consideration for their shares of Inland common stock that otherwise would have been received in connection with the merger. Instead, Inland will remain an independent company.

What happens if I sell my shares of Inland common stock after the record date but before the special meeting?

The record date of the special meeting is earlier than the date of the special meeting and the date that the merger is expected to be completed. If you sell or otherwise transfer your shares of Inland common stock after the record date but before the date of the special meeting, you will retain your right to vote at the special meeting (provided that such shares remain outstanding on the date of the special meeting), but you will not have the right to receive the merger consideration to be received by Inland stockholders in the merger. In order to receive the merger consideration, you must hold your shares of Inland common stock through completion of the merger.

TABLE OF CONTENTS

Will I be able to sell the shares of Byline common stock that I receive in the merger?

Yes. You may freely trade the shares of Byline common stock issued in the merger, except for shares issued to any stockholder who may be deemed to be an “affiliate” of Byline for purposes of Rule 144 under the Securities Act of 1933, as amended (which we refer to as the Securities Act). Persons who may be deemed to be affiliates of Byline include individuals or entities that control, are controlled by, or are under common control with Byline and may include the executive officers, directors and significant stockholders of Byline.

Are there risks involved in the undertaking the merger?

Yes. In evaluating the merger, Inland stockholders should carefully consider the factors discussed in “Risk Factors” beginning on page 27 and other information about Byline included in the documents incorporated by reference into this proxy statement/prospectus, as well as the information about Inland included in this proxy statement/prospectus.

Should Inland stockholders send in their stock certificates now?

No. Inland stockholders SHOULD NOT send in any stock certificates now. If the merger is approved, transmittal materials with instructions for their completion will be provided to Inland stockholders under separate cover and the stock certificates should be sent at that time.

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

Inland stockholders may receive more than one set of voting materials, including multiple copies of this proxy statement/prospectus and multiple proxy cards or voting instruction cards. If you are a stockholder of record and your shares are registered in more than one name, you will receive more than one proxy card. If you hold shares of Inland common stock in more than one brokerage account, you may receive a separate voting instruction card for each brokerage account in which you hold such shares. In each case, please complete, sign, date and return 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 Inland common stock that you own.

Whom should I contact if I have any questions about the proxy materials or voting?

If you are an Inland stockholder and have any questions about the proxy materials or if you need assistance submitting your proxy or voting your shares or need additional copies of this proxy statement/prospectus or the enclosed proxy card, you should contact Peter Stickler at (877) 908-6555.

Merger Consideration (page 63)

Recommendation of the Inland Board of Directors (page 43)

After careful consideration, the Inland board unanimously recommends that Inland stockholders vote “FOR” the merger proposal and “FOR” the adjournment proposal. For a more complete description of Inland’s reasons for the merger and the recommendations of the Inland board, please see the section entitled “The Merger — Recommendation of the Inland Board of Directors and Inland’s Reasons for the Merger”.

Opinion of Inland’s Financial Advisor (page 44)

At the November 14, 2022 meeting of the Inland board, a representative of Inland’s financial advisor, Piper Sandler & Co., which we refer to as Piper Sandler, rendered Piper Sandler’s oral opinion, which was subsequently confirmed by delivery of a written opinion to the Inland board, dated November 14, 2022, as to the fairness, as of such date, from a financial point of view, to the holders of Inland’s outstanding common stock of the merger consideration to be received by such holders in the merger pursuant to the merger agreement, based upon and subject to the qualifications, assumptions and other matters considered in connection with the preparation of its opinion.

The full text of the written opinion of Piper Sandler, dated November 14, 2022, which sets forth, among other things, the various qualifications, assumptions and limitations on the scope of the review undertaken by Piper Sandler, is attached as Appendix C to this proxy statement/prospectus. Piper Sandler

TABLE OF CONTENTS

provided its opinion for the information and assistance of the Inland board (solely in its capacity as such) in connection with, and for purposes of, the Inland board’s consideration of the merger and Piper Sandler’s opinion only addressed whether the merger consideration to be received by the holders of Inland common stock in the merger pursuant to the merger agreement was fair, from a financial point of view, to such holders. The opinion of Piper Sandler does not address any other term or aspect of the merger agreement or the transactions contemplated thereby. Piper Sandler’s opinion does not constitute a recommendation to the Inland board or any holder of Inland common stock as to how the Inland board, such stockholder or any other person should vote or otherwise act with respect to the merger or any other matter.

Inland Special Meeting of Stockholders (page 32)

The special meeting will be held at 2:00 p.m., local time, on Tuesday, May 30, 2023, at The Legacy Room, 2901 Butterfield Road, Oak Brook, Illinois 60523. At the special meeting, holders of shares of Inland common stock will be asked to approve the merger proposal and the adjournment proposal.

The Inland board has fixed the close of business on April 21, 2023 as the record date for determining the holders of shares of Inland common stock entitled to receive notice of and to vote at the special meeting. As of the close of business on the record date, there were 33,628,162 shares of Inland common stock outstanding and entitled to vote at the special meeting held by approximately 300 stockholders of record. Each share of Inland common stock entitles the holder to one vote on each proposal to be considered at the special meeting.

As of the close of business on the record date, directors and executive officers of Inland and their affiliates owned and were entitled to vote 27,296,753 shares of Inland common stock, representing approximately 81.17% of the shares of Inland common stock outstanding on that date. As of the close of business on the record date, Byline beneficially held no shares of Inland common stock.

Mr. Goodwin, in his capacity as a beneficial owner of shares of Inland common stock, has entered into a voting agreement with Byline, in which Mr. Goodwin has agreed to vote all shares of Inland common stock that he beneficially owns and has the power to vote in favor of the merger proposal and any other matter that is required to be approved by the stockholders of Inland to facilitate the transactions contemplated by the merger agreement. Mr. Goodwin has also agreed to vote against any proposal made in opposition to the approval of the merger or in competition with the merger agreement and against any other acquisition proposal. As of the close of business on the record date, Mr. Goodwin beneficially owned, in the aggregate, 24,922,465.50 shares of Inland common stock, allowing him to exercise approximately 74.11% of the voting power of Inland common stock.

Approval of the merger proposal requires the affirmative vote of holders of two-thirds of the outstanding shares of Inland common stock entitled to vote at the special meeting. Approval of the adjournment proposal requires the affirmative vote of the majority of the shares having voting power present in person or represented by proxy at a duly held meeting at which a quorum is present.

Interests of Inland Directors and Executive Officers in the Merger (page 56)

In considering the recommendation of the Inland board, Inland stockholders should be aware that the directors and executive officers of Inland have certain interests in the merger that may be different from, or in addition to, the interests of Inland stockholders generally. The Inland board was aware of these interests and considered them, among other matters, in making its recommendation that Inland stockholders vote to approve the merger proposal. These interests include:

•

Certain executive officers and other employees of Inland Bank have outstanding options to purchase shares of Inland common stock, each of which will be cancelled in exchange for a cash payment equal to the product of:

(1)

the difference between (i) the sum of (x) the product of the exchange ratio multiplied by the Byline closing price plus (y) the cash consideration, less (ii) the exercise price per share of such Inland stock option, multiplied by

(2)

the number of shares of Inland common stock covered by such option.

TABLE OF CONTENTS

•

Certain executive officers and other employees of Inland Bank will receive a payment pursuant to their existing employment agreement or change in control agreement with Inland Bank in connection with the closing of the merger. Specifically, Peter Stickler, President and CEO of Inland Bank, will receive a change in control payment of $2,055,360, Deborah Bartelt, Executive Vice President of Inland Bank, will receive a change in control payment of $893,241, Paul Berley, Chief Financial Officer of Inland Bank, will receive a change in control payment of $243,750, and Dan Healy, Senior Vice President of Inland Bank, will receive a change in control payment of $252,450;

•

Certain executive officers and other employees of Inland Bank are entitled to receive retention cash bonus awards, in an aggregate amount not to exceed $1,178,690, that, to the extent not already paid, will be payable on the next regularly scheduled payroll date following the closing date or the bank conversion date, as applicable; provided that the employee remains employed through the date of payment;

•

Prior to the effective time but to be effective at the effective time, Byline has agreed to appoint one person, mutually agreed upon by both Inland and Byline, as a director to Byline’s board and to re-nominate such person as a director for a one-year term at each of Byline’s annual meeting of stockholders to be held in 2023 and 2024. If, during this period, such person for any reason ceases to serve as a director or chooses for any reason not to stand for re-election, Byline will promptly appoint another person as a director to Byline’s board, as mutually agreed upon by Inland and Byline. However, in the event that, at any time during this period, Mr. Goodwin’s beneficial ownership of Byline common stock falls below five percent (5%) of the then outstanding shares of Byline common stock, Byline may, but will not be required to, choose not to re-nominate the previously mutually agreed upon director then serving on Byline’s board at the next annual meeting of stockholders; and

•

Inland’s directors and executive officers are entitled to certain continued indemnification and coverage under directors’ and officers’ liability insurance policies post-closing pursuant to the merger agreement.

For a more complete description of the interests of Inland’s directors and executive officers in the merger, see “The Merger — Interests of Inland Directors and Executive Officers in the Merger”.

Management and Board of Directors of Byline After the Merger (page 56)

Except as described above under “— Interests of Inland Directors and Executive Officers in the Merger”, the directors and officers of Byline immediately prior to the effective time will be the directors and officers of the surviving corporation after the merger and parent merger until the earlier of their resignation or removal or until their respective successors are duly appointed and qualified.

Regulatory Approvals Required for the Merger (page 57)

The merger cannot proceed without obtaining all requisite regulatory approvals. Byline and Inland have agreed to use their reasonable best efforts to obtain the required approvals. The merger of Byline and Inland is subject to prior approval of the Board of Governors of the Federal Reserve System (which we refer to as the Federal Reserve) or through delegated authority to the Federal Reserve Bank of Chicago, unless the Federal Reserve waives this requirement pursuant to Regulation Y under the BHC Act. In accordance with Regulation Y, on January 13, 2023, Byline submitted a request to the Federal Reserve Bank of Chicago for a waiver from the requirement under Section 3 of the BHC Act for prior approval of the Federal Reserve. On April 12, 2023, the Federal Reserve granted the requested waiver.

Immediately following the completion of the parent merger, Inland Bank will merge with and into Byline Bank, with Byline Bank as the resulting bank. The bank merger will be subject to approval by the Federal Deposit Insurance Corporation, which we refer to as the FDIC, and the Illinois Department of Financial and Professional Regulation, which we refer to as the IDFPR. Byline Bank submitted applications with the FDIC and the IDFPR on January 13, 2023 seeking the necessary approvals for the bank merger. The FDIC approved the bank merger on February 24, 2023, and the IDFPR approved the bank merger on March 31, 2023. The U.S. Department of Justice has authority to comment on the merger and the bank

merger during the regulatory approval process of the FDIC and had fifteen (15) days following the approval by the FDIC on February 24, 2023 to challenge the merger on antitrust grounds. The U.S. Department of Justice did not challenge the merger or bank merger during such fifteen (15) day period.

Neither Byline nor Inland is aware of any material governmental approvals or actions that are required for completion of the merger or bank merger other than those described above, all of which have been obtained. It is presently contemplated that if any such additional governmental approvals or actions are required, those approvals or actions will be sought. However, there can be no assurance that any additional approvals or actions will be obtained.

Byline’s obligation to consummate the merger is also subject to the fulfilment or written waiver of each of the following conditions:

•

the accuracy of representations and warranties of Inland in the merger agreement, subject to certain materiality standards, including Inland’s representation and warranty that no material adverse effect with respect to Inland has occurred since December 31, 2021;

•

performance by Inland in all material respects of its obligations under the merger agreement;

•

receipt by Byline of an opinion of its counsel, in form and substance reasonably acceptable to Byline, dated as of the closing date, to the effect that, on the basis of facts, representations and assumptions described in such opinion, for U.S. federal income tax purposes, the merger and the parent merger, taken together, will be treated as a single integrated transaction that qualifies as a “reorganization” within the meaning of Section 368(a) of the Code;

Acquisition Proposals (page 73)

Under the terms of the merger agreement, Inland has agreed that it will not and will cause its subsidiaries and affiliates not to:

•

initiate, solicit, knowingly encourage or knowingly facilitate in any way inquiries or proposals with respect to an acquisition proposal; or

•

engage in any negotiations concerning, or provide any confidential nonpublic information to, or have any discussions with, any person relating to an acquisition proposal.

However, the above restriction does not prevent Inland or its board of directors from:

•

providing information in response to a request therefor by a person who has made an unsolicited bona fide written acquisition proposal if Inland receives from the person so requesting such information an executed confidentiality agreement on terms not less restrictive to the other party than those contained in the confidentiality agreement between Byline and Inland; or

•

engaging in any negotiations or discussions with any person who has made an unsolicited bona fide written acquisition proposal;

only if, however, in each case referred to in the bullet points above, (i) the Inland board concludes in good faith (after consultation with outside legal counsel and financial advisor) that (A) such acquisition proposal either constitutes a superior proposal (as defined in the section entitled “Description of the Merger Agreement — Acquisition Proposals”) or would reasonably be expected to result in a superior proposal and (B) the failure to take such action would reasonably be expected to violate the directors’ fiduciary duties under applicable law; and (ii) Inland has provided notice to Byline of its intention to provide information to the person who has made such acquisition proposal, and Inland has provided such information to Byline.

Further, the merger agreement provides that, unless the merger agreement is contemporaneously terminated in accordance with its terms, the Inland board will not cause or permit Inland to enter into any letter of intent, memorandum of understanding, agreement in principle, acquisition agreement, merger agreement or other agreement (other than a confidentiality agreement referred to above) relating to any acquisition proposal.

For more information, please see the section entitled “Description of the Merger Agreement — Acquisition Proposals”.

Termination of the Merger Agreement (page 75)

Byline and Inland may mutually agree in writing to terminate the merger agreement at any time prior to the effective time. Subject to certain conditions described in the merger agreement, either Byline or Inland may also terminate the merger agreement if:

•

Inland stockholders do not adopt the merger agreement by the conclusion of the special meeting;

•

any regulatory authority has denied approval of any of the transactions contemplated by the merger agreement and such denial has become final and non-appealable, or any application for a necessary regulatory approval has been withdrawn at the request of a regulatory authority and such regulatory authority would not accept the re-filing of such application, provided that this right to terminate is not available to a party whose failure to fulfill its covenants under the merger agreement has been the cause of the denial or withdrawal of regulatory approval; or

TABLE OF CONTENTS

•

the merger is not completed by the outside date, which is June 30, 2023, or if the sole impediment to closing is receipt of required regulatory approvals, September 30, 2023, provided that this right to terminate is not available to a party whose failure to fulfill its covenants under the merger agreement has been the cause of, or materially contributed to, the failure of the merger to be completed before such date.

In addition, Inland may terminate the merger agreement if there is a breach of any of the covenants, agreements, representations or warranties of Byline such that the applicable conditions to Inland’s obligation to close the merger set forth in the merger agreement would not be satisfied, and such breach has not been, or cannot be, cured prior to the earlier of the outside date or thirty (30) days after notice to Byline from Inland.

In addition, Byline may terminate the merger agreement if there is a breach of any of the covenants, agreements, representations or warranties of Inland such that the applicable conditions to Byline’s obligation to close the merger set forth in the merger agreement would not be satisfied, and such breach has not been, or cannot be, cured prior to the earlier of the outside date or thirty (30) days after notice to Inland from Byline.

Byline may also terminate the merger agreement prior to the adoption of the merger agreement by the Inland stockholders, if:

•

the Inland board submits the merger agreement to its stockholders without a recommendation for approval or with material and adverse conditions on such approval, or otherwise withdraws or materially and adversely modifies such recommendation;

•

Inland recommends to its stockholders an acquisition transaction other than the merger;

•

Inland breaches its obligations under the merger agreement to convene the special meeting in accordance with its obligations under the merger agreement prior to the outside date;

•

Termination Fee (page 76)

Inland has agreed to pay to Byline a cash termination fee in an amount equal to $6,840,000 in the following circumstances:

•

•

a bona fide acquisition proposal is publicly announced or otherwise made known to the Inland board prior to the event giving rise to termination of the merger agreement and (a) the merger agreement is terminated (1) by either Byline or Inland because the merger agreement is not approved by the requisite votes of Inland stockholders by the conclusion of the special meeting, (2) by Byline because Inland has breached a representation, warranty, covenant or agreement or (3) by Byline because closing has not occurred by the outside date and all conditions to Inland’s obligation to close the merger have been satisfied (other than the adoption of the merger agreement by the Inland stockholders and the receipt of the applicable tax opinion from its counsel) and (b) prior to the

TABLE OF CONTENTS

twelve month anniversary of such termination, Inland consummates, or enters into a definitive agreement to consummate, an acquisition transaction.

For more information, please see the section entitled “Description of the Merger Agreement — Termination Fee”.

Voting Agreement (page 76)

Mr. Goodwin, in his capacity as a beneficial owner of shares of Inland common stock, has entered into a voting agreement with Byline pursuant to which he has agreed to vote all shares of Inland common stock that he beneficially owns and has the power to vote in favor of the merger proposal and any other matter that is required to be approved by the stockholders of Inland to facilitate the transactions contemplated by the merger agreement. Mr. Goodwin has also agreed to vote against any proposal made in opposition to the approval of the merger or in competition with the merger agreement and against any other acquisition proposal. As of the close of business on the record date, Mr. Goodwin beneficially owned, 24,922,465.50 shares of Inland common stock, allowing him to exercise approximately 74.11% of the voting power of Inland common stock.

For more information, please see the section entitled “Description of the Merger Agreement — Voting Agreement”.

Treatment of Inland Stock Options (page 40)

Accounting Treatment of the Merger (page 59)

For accounting and financial reporting purposes, the merger will be accounted for under the acquisition method of accounting for business combinations in accordance with accounting principles generally accepted in the United States, which we refer to as GAAP.

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

The integrated merger is intended to constitute a single integrated transaction that for federal income tax purposes will qualify as a reorganization within the meaning of Section 368(a) of the Code. However, neither Inland nor Byline has requested or received a ruling from the Internal Revenue Service that the integrated merger will qualify as a reorganization. If the integrated merger qualifies as a reorganization for U.S. federal income tax purposes, a U.S. holder of Inland common stock who receives Byline common stock and cash (other than cash received in lieu of a fractional share of Byline common stock) in exchange for shares of Inland common stock pursuant to the merger, generally will recognize gain (but not loss) in an amount equal to the lesser of (1) the amount of gain realized (i.e., the excess of the sum of the amount of cash and the fair market value of the Byline common stock received pursuant to the merger over such holder’s adjusted tax basis in the shares of Inland common stock surrendered in the exchange) and (2) the amount of cash received pursuant to the merger (excluding any cash received in lieu of a fractional share of Byline common stock). In addition, a U.S. holder of Inland common stock generally will recognize gain or loss with respect to cash received in lieu of a fractional share of Byline common stock. It is a condition to the completion of the merger that Byline and Inland receive written opinions from their respective counsel to the effect that the integrated merger will qualify as a reorganization within the meaning of Section 368(a) of the Code.

TABLE OF CONTENTS

Tax matters are complicated and the tax consequences of the integrated merger to each Inland stockholder may depend on such stockholder’s particular facts and circumstances. Inland stockholders are urged to consult their tax advisors to understand fully the tax consequences to them of the integrated merger. For more information, please see the section entitled “Material U.S. Federal Income Tax Consequences of the Integrated Merger”.

Comparison of Stockholders’ Rights (page 81)

The rights of Inland stockholders who continue as Byline stockholders after the merger will be governed by the DGCL, Byline’s amended and restated certificate of incorporation, which we refer to as Byline’s certificate of incorporation, and Byline’s amended and restated bylaws, which we refer to as Byline’s bylaws, rather than by the articles of incorporation and bylaws of Inland.

GAAP RECONCILIATION AND MANAGEMENT EXPLANATION
OF NON-GAAP FINANCIAL MEASURES

Some of the financial measures included in “Selected Historical Consolidated Financial Information for Byline” are not measures of financial performance in accordance with GAAP. Byline’s management uses the non-GAAP financial measures set forth below in its analysis of Byline’s performance:

•

“Adjusted net income” and “adjusted diluted earnings per share” exclude certain significant items, which include incremental income tax benefit related to federal corporate income tax reductions, impairment charges on assets held for sale and right-of-use asset (‘‘ROU”), merger-related expenses, and core system conversion expenses adjusted for applicable income tax. Byline’s management believes the significant items are not indicative of or useful to measure Byline’s operating performance on an ongoing basis.

•

“Adjusted non-interest expense” is non-interest expense excluding certain significant items, which include impairment charges on assets held for sale and ROU, merger-related expenses, and core system conversion expenses.

•

“Adjusted efficiency ratio” is adjusted non-interest expense less amortization of intangible assets divided by net interest income and non-interest income. Management believes the metric is an important measure of Byline’s operating performance on an ongoing basis.

•

“Adjusted non-interest expense to average assets” is adjusted non-interest expense divided by average assets. Byline’s management believes the metric is an important measure of Byline’s operating performance on an ongoing basis.

•

“Adjusted return on average stockholders’ equity” is adjusted net income divided by average stockholders’ equity. Byline’s management believes the metric is an important measure of Byline’s operating performance on an ongoing basis.

•

“Adjusted return on average assets” is adjusted net income divided by average assets. Byline’s management believes the metric is an important measure of Byline’s operating performance on an ongoing basis.

•

“Non-interest income to total revenues” is non-interest income divided by net interest income plus non-interest income. Byline’s management believes that it is standard practice in the industry to present non-interest income as a percentage of total revenue. Accordingly, Byline’s management believes providing these measures may be useful for peer comparison.

•

“Pre-tax pre-provision net income” is pre-tax income plus the provision for credit losses. Byline’s management believes this metric is important due to the tax benefit resulting from the decrease in the federal corporate income tax rate. The metric demonstrates income excluding the tax provision and excludes the provision for credit losses.

•

“Adjusted pre-tax pre-provision net income” is pre-tax pre-provision net income excluding certain significant items, which include impairment charges on assets held for sale and ROU, merger-related expenses, and core system conversion expenses. Byline’s management believes the metric is an important measure of Byline’s operating performance on an ongoing basis.

��

“Pre-tax pre-provision return on average assets” is pre-tax income plus the provision for credit losses, divided by average assets. Byline’s management believes this ratio demonstrates profitability excluding the tax provision or benefit and excludes the provision for credit losses.

•

“Adjusted pre-tax pre-provision return on average assets” excludes certain significant items, which include impairment charges on assets held for sale and ROU, merger-related expenses, and core system conversion expenses.

•

“Tangible common equity” is defined as total stockholders’ equity reduced by preferred stock and goodwill and other intangible assets. Byline’s management does not consider servicing assets as an intangible asset for purposes of this calculation.

•

“Tangible assets” is defined as total assets reduced by goodwill and other intangible assets. Byline’s management does not consider servicing assets as an intangible asset for purposes of this calculation.

TABLE OF CONTENTS

•

“Tangible book value per common share” is calculated as tangible common equity, which is stockholders’ equity reduced by preferred stock and goodwill and other intangible assets, divided by total shares of common stock outstanding. Byline’s management believes this metric is important due to the relative changes in the book value per share exclusive of changes in intangible assets.

•

“Tangible common equity to tangible assets” is calculated as tangible common equity divided by tangible assets, which is total assets reduced by goodwill and other intangible assets. Byline’s management believes this metric is important to investors and analysts interested in relative changes in the ratio of total stockholders’ equity to total assets, each exclusive of changes in intangible assets.

•

“Tangible net income available to common stockholders” is net income available to common stockholders excluding after-tax intangible asset amortization.

•

“Adjusted tangible net income available to common stockholders” is tangible net income available to common stockholders excluding certain significant items. Byline’s management believes the metric is an important measure of Byline’s operating performance on an ongoing basis.

•

“Return on average tangible common stockholders’ equity” is tangible net income available to common stockholders divided by average tangible common stockholders’ equity. Byline’s management believes the metric is an important measure of Byline’s operating performance on an ongoing basis.

•

“Adjusted return on average tangible common stockholders’ equity” is adjusted tangible net income available to common stockholders divided by average tangible common stockholders’ equity. Byline’s management believes the metric is an important measure of Byline’s operating performance on an ongoing basis.

Byline believes that these non-GAAP financial measures provide useful information to its management and investors that is supplementary to its financial condition, results of operations and cash flows computed in accordance with GAAP; however, Byline acknowledges that its non-GAAP financial measures have a number of limitations. As such, you should not view these disclosures as a substitute for results determined in accordance with GAAP financial measures that Byline and other companies use. Byline’s management also uses these measures for peer comparison.

The information presented does not reflect the actual value of the merger consideration that will be received by holders of Inland common stock in the merger. The exchange ratio is fixed (subject to potential adjustment, as described in “Description of the Merger Agreement — Merger Consideration”) and therefore the value of the merger consideration at the closing of the merger will be based on the price of Byline common stock on the date the merger is completed. The information presented above solely illustrates the implied value of the merger consideration based on the share price of Byline common stock on the dates set forth above.

Inland Information

There is no established public trading market for shares of Inland common stock and no broker makes a market in the stock.

TABLE OF CONTENTS

RISK FACTORS

In addition to the other information contained in or incorporated by reference into this proxy statement/ prospectus, including the matters addressed under the caption entitled “Cautionary Statement Regarding Forward-Looking Statements,” and in “Item 1A. Risk Factors” in Byline’s Annual Report on Form 10-K for the year ended December 31, 2022, Inland stockholders should carefully consider the following factors in deciding whether to vote for Inland’s proposals. Please see the sections entitled “Where You Can Find More Information” and “Incorporation of Certain Documents by Reference”.

Risks Related to the Merger and Byline’s and
Inland’s Businesses upon Completion of the Merger

The value of the merger consideration that consists of Byline common stock will fluctuate based on the trading price of Byline common stock.

The number of shares of Byline common stock to be issued in the merger will not automatically adjust based on the trading price of Byline common stock, and the market value of those shares at the effective time may vary significantly from the current price of Byline common stock or the price of Byline common stock at the time of the special meeting. Accordingly, at the time of the special meeting, Inland stockholders will not know or be able to calculate the market value of the shares of Byline common stock they might receive upon the completion of the merger.

The market price of Byline common stock could be subject to significant fluctuations due to changes in sentiment in the market regarding Byline’s operations or business prospects, including market sentiment regarding Byline’s entry into the merger agreement. These risks may be affected by, among other things:

•

operating results that vary from the expectations of Byline’s management or of securities analysts and investors;

•

operating and securities price performance of companies that investors consider to be comparable to Byline;

•

announcements of strategic developments, acquisitions, dispositions, financings, and other material events by Byline or its competitors; and

•

changes in global financial markets and economies and general market conditions, such as interest or foreign exchange rates, stock, commodity, credit or asset valuations or volatility.

Stock price changes may also result from a variety of other factors, many of which are outside of the control of Byline and Inland, including changes in the business, operations or prospects of Byline or Inland, regulatory considerations, and general business, market, industry or economic conditions. For more information, see “Description of the Merger Agreement — Merger Consideration” and “Description of the Merger Agreement — Termination”.

The merger consideration may be adjusted only under certain limited circumstances as set forth in the merger agreement. In the event that Inland’s tangible common equity (as calculated pursuant to merger agreement and set forth on Inland’s final closing balance sheet) is less than $135.350 million, then the aggregate cash consideration will be reduced on a dollar-for-dollar basis by the amount of such shortfall.

The market price of Byline common stock after the merger may be affected by factors different from those affecting the shares of Inland or Byline currently.

Upon completion of the merger, holders of Inland common stock will become holders of Byline common stock. Byline’s business differs from that of Inland. Accordingly, the results of operations of the

TABLE OF CONTENTS

combined company and the market price of Byline common stock after the completion of the merger may be affected by factors different from those currently affecting the independent results of operations of each of Byline and Inland. For a discussion of the business and market of each of Byline and Inland and of some important factors to consider in connection with the business of each of Byline and Inland, please see “Information About the Companies”.

Inland stockholders will have a reduced ownership and voting interest after the merger and will exercise less influence over management.

Upon the completion of the merger, each former Inland stockholder will have a percentage ownership of Byline that is smaller than such stockholder’s current percentage ownership of Inland. Based on the number of issued and outstanding shares of Byline common stock and Inland common stock on April 24, 2023, and assuming no adjustment in the number of shares of Byline common stock to be issued as merger consideration pursuant to the merger agreement, stockholders of Inland, as a group, will receive shares in the merger constituting approximately 14% of Byline common stock expected to be outstanding immediately after the merger (without giving effect to any Byline common stock held by Inland stockholders prior to the merger). As a result, Inland stockholders, as a group, will have less influence on the board of directors, management and policies of Byline following the merger than they now have on the board of directors, management and policies of Inland.

Byline may fail to realize the anticipated benefits of the merger.

Byline and Inland have operated independently and will continue to do so until the completion of the merger. The success of the merger, including anticipated benefits and cost savings, will depend on, among other things, Byline’s ability to successfully combine the businesses of Byline and Inland, including by minimizing any disruptions to the existing customer relationships and business functions of Byline or Inland, and avoiding any inconsistencies in standards, controls, procedures and policies. If Byline is not able successfully to achieve these objectives, the anticipated benefits of the merger may not be realized fully, or at all, or may take longer to realize than expected. Failure to achieve these anticipated benefits could result in increased costs, decreases in the amount of expected revenues and diversion of management’s time and energy and could have an adverse effect on Byline’s business, financial condition, operating results and prospects. Among the factors considered by the boards of directors of each of Byline and Inland in connection with their respective approvals of the merger agreement were the anticipated benefits that could result from the merger. There can be no assurance that these benefits will be realized within the time periods contemplated or at all. To review the reasons for the merger in more detail, see “The Merger — Recommendation of the Inland Board of Directors and Inland’s Reasons for the Merger”.

Regulatory approvals may not be received, may take longer than expected or may impose conditions that are not presently anticipated or cannot be met.

Before the transactions contemplated in the merger agreement can be completed, various approvals must be obtained from bank regulatory agencies and other governmental authorities. In deciding whether to grant regulatory approval, the relevant governmental entities will consider a variety of factors, including the regulatory standing of each of the parties. An adverse condition or development in either party’s regulatory standing or other factors could prevent or delay the receipt of one or more of the required regulatory approvals. Even if granted, the terms and conditions of the approvals may impose requirements, limitations or costs or place restrictions on the conduct of the combined company’s business. Despite the parties’ commitments to use their reasonable best efforts to obtain regulatory approvals, under the terms of the merger agreement, Byline and Inland will not be required to complete the merger if any such approval imposes a burdensome condition. There can be no assurance that regulators will not impose conditions, terms, obligations or restrictions and that such conditions, terms, obligations or restrictions will not have the effect of delaying the completion of the merger, imposing additional material costs on or materially limiting the revenues of the combined company following the merger or otherwise reduce the anticipated benefits of the merger if the merger were completed successfully within the expected timeframe. Additionally, the completion of the merger is subject to the satisfaction or waiver of certain other closing conditions, including the absence of certain orders, injunctions or decrees by any governmental authority that would prohibit or make illegal

TABLE OF CONTENTS

the completion of the merger. Please see the section entitled “Description of the Merger Agreement — Conditions to Consummation of the Merger”.

Because of the closing conditions in the merger agreement and the ability of either Byline or Inland to terminate the merger agreement in specific instances, there can be no assurance when or if the merger will be completed.

The merger agreement is subject to a number of conditions that must be satisfied or waived to complete the merger. Those conditions include, among other things, (i) the accuracy of the other party’s representations and warranties, subject to certain materiality standards, including the accuracy of the other party’s representation and warranty of the absence of a material adverse effect on the other party since December 31, 2021, (ii) the other party’s performance in all material respects of its obligations under the merger agreement, (iii) the adoption of the merger agreement and the transactions contemplated thereby by Inland stockholders, (iv) the absence of any proceeding in connection with, or that could prevent, delay, make illegal or interfere with, any of the transactions contemplated by the merger agreement, (v) the receipt of required regulatory approvals, including the approval of certain federal and state banking agencies, (vi) the effectiveness of the registration statement of which this proxy statement/prospectus forms a part, (vii) the receipt by each party of an opinion from such party’s counsel to the effect that the integrated merger qualifies as a “reorganization” within the meaning of Section 368(a) of the Code, and (viii) the approval for listing on the NYSE of the shares of Byline common stock issuable in the merger.

In addition, Byline’s obligation to complete the merger is subject to dissenters’ rights having been exercised by the holders of no more than 5% of Inland common stock, receipt by Inland of certain third party consents and the delivery to Byline from Inland of the certificate or certificates representing the shares of common stock of Inland Bank held by Inland. These conditions to the closing of the merger may not be fulfilled in a timely manner or at all, and, accordingly, the merger may not be completed. In addition, the parties can mutually decide to terminate the merger agreement at any time, before or after the required Inland stockholder approval, or Byline or Inland may elect to terminate the merger agreement in certain other circumstances. Please see the section entitled “Description of the Merger Agreement — Termination”.

Termination of the merger agreement could negatively affect Inland.

If the merger agreement is terminated there may be various adverse consequences to Inland. For example, Inland’s business may have been adversely affected by the failure to pursue other beneficial opportunities due to the focus of management on the merger, without realizing any of the anticipated benefits of completing the merger. In addition, if the merger agreement is terminated and the Inland board seeks another merger or business combination, Inland stockholders cannot be certain that Inland will be able to find a party willing to offer equivalent or more attractive consideration than the consideration Byline has agreed to provide in the merger, or that such other merger or business combination will be completed. Additionally, if the merger agreement is terminated, under certain circumstances Inland may be required to pay Byline a termination fee of $6,840,000. Please see the section entitled “Description of the Merger Agreement — Termination Fee”.

Inland directors and executive officers have interests in the merger different from or in addition to the interests of Inland stockholders generally.

The interests of some of the directors and executive officers of Inland may be different from those of Inland stockholders generally. While the Inland board knew about and considered these interests when making its decision to approve the merger agreement and in recommending that Inland stockholders vote in favor of adopting the merger agreement, Inland stockholders should consider these interests when determining whether to vote to adopt the merger agreement. Please see the section entitled “The Merger — Interests of Inland Directors and Executive Officers in the Merger”.

The merger agreement contains provisions that may discourage other companies from trying to acquire Inland for greater merger consideration.

The merger agreement contains provisions that may discourage a third party from submitting a business combination proposal to Inland that might result in greater value to Inland stockholders than the

TABLE OF CONTENTS

proposed merger with Byline or may result in a potential competing acquirer proposing to pay a lower per share price to acquire Inland than it might otherwise have proposed to pay absent such provisions. These provisions include a general prohibition on Inland from soliciting, or entering into discussions with any third party regarding, any acquisition proposal or offers for competing transactions, subject to certain exceptions relating to the exercise of fiduciary duties by the Inland board. In addition, Inland may be required to pay Byline a termination fee of $6,840,000 upon termination of the merger agreement in certain circumstances involving acquisition proposals for competing transactions. Please see the sections entitled “Description of the Merger Agreement — Termination” and “Description of the Merger Agreement — Termination Fee”.

The opinion of Inland’s financial advisor delivered to the Inland board prior to the signing of the merger agreement does not reflect changes in circumstances between the date of the opinion and the completion of the merger.

On November 14, 2022, the Inland board received an opinion from Piper Sandler, its financial advisor, as to the fairness, as of such date, from a financial point of view, to the holders of Inland’s outstanding common stock of the merger consideration to be received by such holders in the merger pursuant to the merger agreement, based upon and subject to the qualifications, assumptions and other matters considered in connection with the preparation of its opinion. Piper Sandler’s written opinion was delivered to the Inland board on November 14, 2022. Changes in the operations and prospects of Inland or Byline may significantly alter the value of Inland or the price of Byline common stock by the time the merger is completed. The opinion does not speak as of the date of this proxy statement/prospectus or the time the merger will be completed or as of any date other than the date of such opinion.

For a description of the opinion that Inland received from its financial advisor, please refer to the section entitled “The Merger — Opinion of Inland’s Financial Advisor”. A copy of Piper Sandler’s opinion is also attached to this proxy statement/prospectus as Appendix C.

Byline and Inland will incur transaction and integration costs in connection with the merger.

Each of Byline and Inland has incurred and expects that it will incur significant, nonrecurring costs in connection with consummating the merger. In addition, Byline will incur integration costs following the completion of the merger, including facilities and systems consolidation costs and employment- related costs. There can be no assurances that the expected benefits and efficiencies related to the integration of the businesses will be realized to offset these transaction and integration costs over time. See the risk factor entitled “— Byline may fail to realize the anticipated benefits of the merger”. Byline and Inland may also incur additional costs to maintain employee morale and to retain key employees. Byline and Inland will also incur significant legal, financial advisor, accounting, banking and consulting fees, fees relating to regulatory filings and notices, SEC filing fees, printing and mailing fees and other costs associated with the merger.

The shares of Byline common stock to be received by Inland stockholders in the merger will have different rights from the shares of Inland common stock.

Upon completion of the merger, Inland stockholders will receive merger consideration consisting, in part, of Byline common stock and will become Byline stockholders and their rights as stockholders will be governed by the DGCL and Byline’s certificate of incorporation and bylaws. The rights associated with Inland common stock are different from the rights associated with Byline common stock. Please see the section entitled “Comparison of Stockholders’ Rights” for a discussion of the different rights associated with Byline common stock.

Record Date and Quorum

As of the close of business on the record date, there were 33,628,162 shares of Inland common stock outstanding and entitled to vote at the special meeting held by approximately 300 stockholders of record. Each share of Inland common stock entitles the holder to one vote on each proposal to be considered at the special meeting.

A majority of shares entitled to vote, represented in person or by proxy, constitutes a quorum for transacting business at the special meeting. Abstentions will be counted as represented at the special meeting for purposes of determining the presence or absence of a quorum for all matters voted on at the special meeting.

None of the proposals to be voted on at the special meeting are routine matters for which brokers may have discretionary authority to vote. Consequently, failure to provide instructions to your bank, broker or other nominee on how to vote will result in your shares not being counted as represented for purposes of establishing a quorum at the special meeting. Accordingly, such a failure would have an effect on the outcome of the vote if such failure prevents a quorum from being established. Please see “— Shares Held in ‘Street Name”‘ below for further information.

As of the close of business on the record date, directors and executive officers of Inland owned and were entitled to vote 27,296,753 shares of Inland common stock, representing approximately 81.17% of the shares of Inland common stock outstanding on that date. As of the close of business on the record date, Byline beneficially held no shares of Inland common stock.

Mr. Goodwin, in his capacity as a beneficial owner of shares of Inland common stock, has entered into a voting agreement with Byline in which Mr. Goodwin has agreed to vote all shares of Inland common stock that he beneficially owns and has the power to vote in favor of the merger proposal and any other matter that is required to be approved by the stockholders of Inland to facilitate the transactions contemplated by the merger agreement. Mr. Goodwin has also agreed to vote against any proposal made in opposition to the approval of the merger or in competition with the merger agreement and against any other acquisition proposal. As of the close of business on the record date, Mr. Goodwin beneficially owned, in the aggregate, 24,922,465.50 shares of Inland common stock, allowing him to exercise approximately 74.11% of the voting power of Inland common stock.

Required Vote

•

Merger Proposal: Approval of the merger proposal requires the affirmative vote of holders of two-thirds of the outstanding shares of Inland common stock entitled to vote at the special meeting.

•

Adjournment Proposal: The adjournment proposal requires the affirmative vote of the majority of the shares having voting power present in person or represented by proxy at a duly held meeting at which a quorum is present.

Treatment of Abstentions; Failure to Vote

For purposes of the special meeting, an abstention occurs when an Inland stockholder attends the special meeting, either in person or represented by proxy, but abstains from voting.

TABLE OF CONTENTS

Abstentions will be counted as represented at the special meeting for purposes of determining the presence or absence of a quorum for all matters voted on at the special meeting.

•

For the merger proposal, if an Inland stockholder present in person at the special meeting abstains from voting, or responds by proxy with an “abstain” vote, it will have the same effect as a vote “AGAINST” the proposal. If an Inland stockholder is not present in person at the special meeting and does not respond by proxy, it will also have the same effect as a vote “AGAINST” the merger proposal.

•

The adjournment proposal requires the affirmative vote of the majority of the shares having voting power present in person or represented by proxy at a duly held meeting at which a quorum is present. Accordingly, for purposes of the adjournment proposal, abstentions will affect the outcome as they will be counted as shares represented at the meeting, but not voted affirmatively in favor of the adjournment proposal.

Voting on Proxies; Incomplete Proxies

Giving a proxy means that a stockholder authorizes the persons named in the proxy to vote such holder’s shares at the special meeting in the manner such holder directs. An Inland stockholder may vote by proxy or in person at the special meeting.

The method of voting by proxy differs for shares held by stockholders of record and shares held in “street name”.

Stockholders of Record

If your shares of Inland common stock are registered directly in your name, you are considered the stockholder of record with respect to these shares. If you hold your shares in your name as a stockholder of record, you may submit your proxy before the special meeting by mail. You must complete, sign, date and return the proxy card in the enclosed envelope. The envelope requires no additional postage if mailed in the United States.

You may also cast your vote in person at the special meeting. Please see “— Attending the Special Meeting and Voting in Person” below for further information.

Inland requests that Inland stockholders vote by completing, dating and signing the accompanying proxy and returning it to Inland as soon as possible in the enclosed postage-paid envelope. When the accompanying proxy is returned properly executed, the shares of Inland common stock represented by it will be voted at the special meeting in accordance with the instructions contained on the proxy card.

If you hold your shares of Inland common stock in your name as a stockholder of record, and you sign and return your proxy card without indicating how to vote on any particular proposal, the shares of Inland common stock represented by the proxy will be voted “FOR” the merger proposal and “FOR” the adjournment proposal.

Shares Held in “Street Name”

If your shares of Inland common stock are held in an account with a bank, broker or other nominee, which we refer to as shares held in “street name,” the bank, broker or other nominee is considered the stockholder of record with respect to these shares and you are the beneficial owner of these “street name” shares.

If your shares are held in “street name” through a broker, bank or other nominee, you will receive instructions from your broker, bank or other nominee that you must follow in order to vote your shares. You should refer to the voting form used by that firm to determine whether you may vote by telephone, Internet or mail.

If your shares are held in “street name,” Inland recommends that you mark, date, sign and promptly mail the voting instruction form provided by your bank, broker or other nominee in accordance with the instructions provided by such nominee. If you do not give your bank, broker or other nominees instructions

TABLE OF CONTENTS

on how to vote your shares of Inland common stock, your bank, broker or other nominees will not be able to vote your shares on either of the proposals at the special meeting and your shares will not be represented at the special meeting.

If your shares are held in “street name” through a broker, bank or other nominee you must either direct your nominee on how to vote your shares or obtain a proxy from such nominee to vote in person at the special meeting. If your shares are held in “street name,” you may only vote in person at the special meeting if you have proof of ownership of your shares of Inland common stock as of the record date and obtain a valid legal proxy from your bank, broker or other nominee that is the stockholder of record of such shares and present such items at the special meeting. Please see “— Attending the Special Meeting and Voting in Person” below for further information.

Every stockholder’s vote is important. Accordingly, each Inland stockholder should promptly submit a proxy, whether or not the stockholder plans to attend the special meeting.

If you are a stockholder of record and your shares are registered in more than one name, you will receive more than one proxy card. If you hold your shares in more than one brokerage account, you may receive a separate voting instruction card for each brokerage account in which you hold shares. In each case, please complete, sign, date and return each proxy card and voting instruction form that you receive.

Shares Held in “Street Name”

If your shares of Inland common stock are held in “street name” through a bank, broker or other nominee, you must provide the bank, broker or other nominee, as the stockholder of record of your shares, with instructions on how to vote your shares. Please follow the instructions provided by your bank, broker or other nominee. You may not vote shares held in “street name” by returning a proxy card directly to Inland or by voting in person at the special meeting unless you provide a “legal proxy,” which you must obtain from your broker, bank or other nominee.

Brokers, banks or other nominees who hold shares in “street name” for the beneficial owner are not allowed to vote with respect to the approval of matters that are “non-routine” without specific instructions from the beneficial owner. Both proposals to be voted on at the special meeting are considered “non-routine” matters and, therefore, brokers, banks and other nominees do not have discretionary voting power on these matters. A “broker non-vote” occurs on an item when (i) a bank, broker or other nominee has discretionary authority to vote on one or more proposals to be voted on at a meeting of stockholders, but is not permitted to vote on other proposals without instructions from the beneficial owner of the shares and (ii) the beneficial owner fails to provide the bank, broker or other nominee with such instructions. Because none of the proposals to be voted on at the special meeting are routine matters for which brokers may have discretionary authority to vote, if you do not instruct your bank, broker or other nominee on how to vote your shares of Inland common stock, your bank, broker or other nominee may not vote such shares on either the merger proposal or the adjournment proposal.

Accordingly, if your shares of Inland common stock are held in “street name” and you do not instruct your broker, bank or other nominee on how to vote your shares, then your bank, broker or other nominee will NOT be able to vote your shares of Inland common stock on either the merger proposal or the adjournment proposal.

•

The adjournment proposal requires the affirmative vote of the majority of the shares having voting power present in person or represented by proxy at a duly held meeting at which a quorum is present. Your bank, broker or other nominee does not have discretionary authority to vote your shares on the special meeting proposals without your instructions. Consequently, failure to provide instructions to your bank, broker or other nominee on how to vote will result in your shares not being counted

TABLE OF CONTENTS

as represented for purposes of establishing a quorum at the special meeting. Accordingly, such a failure would have an effect on the outcome of the vote if such failure prevents a quorum from being established.

Revocability of Proxies and Changes to a Stockholder’s Vote

If you hold your shares of Inland common stock in your name as a stockholder of record, you may change your vote at any time before your proxy is voted at the special meeting. You may do this in one of three ways:

•

first, by sending a notice of revocation stating that you would like to revoke your proxy;

•

second, by sending a completed proxy card bearing a later date than your original proxy card; or

•

third, by attending the special meeting and voting in person. Attendance at the special meeting will not in itself constitute the revocation of a proxy.

If you are an Inland stockholder of record and you choose to send a written notice of revocation or to mail a new proxy card, you must submit your notice of revocation or your new proxy to:

Inland Bancorp, Inc.
Attn: Peter Stickler
2805 Butterfield Rd
Oak Brook, Illinois 60523
(877) 908-6555

Any proxy that you submitted may also be revoked by voting in person at the special meeting.

If your shares are held in “street name” through a broker, bank or other nominee and you have instructed your nominee how to vote your shares of Inland common stock, you must submit new voting instructions to your nominee. You should follow the instructions you receive from your bank, broker or other nominee on how to change or revoke your vote.

Attending the Special Meeting and Voting in Person

The special meeting will be held at 2:00 p.m., local time, on Tuesday, May 30, 2023, at The Legacy Room, 2901 Butterfield Road, Oak Brook, Illinois 60523.

If you hold your shares of Inland common stock in your name as a stockholder of record and you wish to attend the special meeting and vote in person, please bring valid picture identification.

If your shares are held in “street name” through a broker, bank or other nominee, you may only vote in person at the special meeting if you have proof of ownership of your shares of Inland common stock as of the record date and obtain a valid legal proxy from your bank, broker or other nominee that is the stockholder of record of such shares and present such items at the special meeting. You must also bring valid picture identification.

Any representative of a stockholder who wishes to attend the special meeting must present acceptable documentation evidencing his or her authority, acceptable evidence of ownership by the holder of shares of Inland common stock and an acceptable form of identification.

Dissenters’ Rights

THE MERGER

The following is a discussion of the merger and the material terms of the merger agreement between Byline and Inland. You are urged to read carefully the merger agreement in its entirety, a copy of which is attached as Appendix A to this proxy statement/prospectus and incorporated by reference herein. 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. This section is not intended to provide you with any factual information about Byline or Inland. Such information can be found elsewhere in this proxy statement/prospectus and in the public filings Byline and Inland make with the SEC, as described in the section entitled “Where You Can Find More Information”.

Terms of the Merger

Transaction Structure

Byline’s and Inland’s boards of directors have approved the merger agreement and the transactions contemplated thereby. The merger agreement provides that Butterfield Acquisition Corporation, which we refer to as merger sub, will be merged with and into Inland, with Inland as the surviving corporation and wholly owned subsidiary of Byline (which we refer to as the merger). Immediately following the merger, Inland will be merged with and into Byline, with Byline as the surviving corporation (which we refer to as the parent merger), and immediately following the parent merger, Inland Bank will merge with and into Byline Bank, with Byline Bank as the resulting bank.

Merger Consideration

In the merger, each share of Inland common stock outstanding immediately prior to the effective time, other than shares, if any, owned by Inland or Byline or as to which statutory appraisal rights have been properly exercised and perfected, will be converted into the right to receive the merger consideration consisting of (i) shares of Byline’s common stock equal to the quotient obtained by dividing (A) 6,389,351 by (B) the number of shares of Inland common stock issued and outstanding immediately prior to the effective time (which we refer to as the exchange ratio); and (ii) a cash payment in the amount equal to the quotient obtained by dividing (A) $22,867,150.20 by (B) the number of shares of Inland common stock issued and outstanding immediately prior to the effective time (which we refer to as the cash consideration), subject to adjustment in the event the dollar amount of Inland’s tangible common equity at closing is above or below certain thresholds set forth in the merger agreement; provided, however, that in the event Inland has less than 33,628,162 shares of common stock issued and outstanding at closing, then (1) the Exchange Ratio will be equal to 0.19 share of Byline common stock and (2) the cash consideration will be equal to $0.68, for each share of Inland common stock issued and outstanding at closing, in each case subject to further adjustment as set forth in the merger agreement and as further described in the section entitled “Description of the Merger Agreement — Merger Consideration”.

For each fractional share of Byline common stock that would otherwise be issued, Byline will pay cash in an amount equal to the fraction of a share (rounded to the nearest cent) of Byline common stock which the holder would otherwise be entitled to receive multiplied by the Byline closing price. No interest will be paid or accrue on the cash payable to holders in lieu of fractional shares.

The market value of the stock portion of the merger consideration will fluctuate with the price of Byline common stock, and the value of the shares of Byline common stock that holders of shares of Inland common stock will receive upon consummation of the merger may be different than the value of the shares of Byline common stock that holders of shares of Inland common stock would receive if calculated on the date Byline and Inland announced the merger, on the date that this proxy statement/prospectus is being mailed to Inland stockholders, or on the date of the special meeting of Inland stockholders.

TABLE OF CONTENTS

Treatment of Inland Stock Options

Background of the Merger

As part of its ongoing consideration and evaluation of Inland’s long-term business strategy and prospects, the Inland board and senior management have engaged in periodic strategic reviews during which the Inland board has discussed Inland’s strategic direction, performance and prospects in the context of trends and developments in the markets that it serves, the banking industry and the regulatory environment. During the past several years, Inland’s management has engaged in a variety of informal discussions with possible strategic partners, including discussions focused on possible partnerships with other banking institutions in the Chicagoland area, strategic partnerships with fintech-focused financial providers, as well as the potential sale of Inland to another financial institution. During the initial stages of this process, the Inland board and management did not formally engage a financial advisor to assist in these communications and discussions with potential partners. Inland’s management was committed to providing high-quality products and services to its customers, while also concentrating on providing an appropriate value to Inland’s stockholders and opportunities for Inland’s stockholders to have liquidity of their investment.

In late 2021, Inland’s management engaged in more formal discussions regarding Inland’s strategic alternatives with representatives of Piper Sandler. In December 2021, Inland engaged Piper Sandler to act as Inland’s financial advisor in connection with exploring possible strategic transactions with other financial institutions. In early January 2022, Inland’s board met with representatives from Piper Sander and Barack Ferrazzano Kirschbaum & Nagelberg LLP, Inland’s legal counsel, during which the board discussed the process of moving forward with a possible transaction, as well as their fiduciary duties in connection with, and other questions regarding, possible transactions.

In January 2022, Piper Sandler reached out to a variety of financial institutions headquartered in the Midwest regarding their interest in evaluating a possible strategic transaction with Inland. Inland entered into confidentiality agreements with six financial institutions and Piper Sandler made available certain preliminary information regarding Inland for those institutions to evaluate a possible transaction. Byline was one of those organizations that entered into a confidentiality agreement and evaluated a possible strategic transaction.

In late February of 2022, Piper Sandler met with Inland’s board to evaluate the responses of the financial institutions that were given access to information to evaluate a possible strategic transaction. After a presentation and discussion regarding those responses, the board determined that Byline presented an indication of interest that provided the highest potential long-term value to Inland’s stockholders, while also providing for ongoing continuity of a high level of service to Inland’s customers.

As a result of those discussions, Inland’s board instructed Piper Sandler and Barack Ferrazzano Kirschbaum & Nagelberg LLP to enter into formal discussions with Byline and its financial and legal

TABLE OF CONTENTS

advisors to negotiate and execute a formal indication of interest regarding a possible transaction between Inland and Byline, which indication of interest would be non-binding except for a binding 60-day exclusivity agreement. Following further discussions, on March 3, 2022, the parties entered into an indication of interest that provided for, among other things, an implied value of between $5.50 and $6.00 per share of Inland common stock, comprised of approximately 80% of Byline stock and 20% of cash.

After signing the non-binding indication of interest, Byline was granted access to additional due diligence materials regarding Inland. Over the next several weeks, management teams from both organizations engaged in discussions regarding a possible strategic transaction. The parties also instructed their financial and legal advisors to engage in discussions to further evaluate a transaction and to begin the process of creating an agreement and plan of merger that would include the terms of the non-binding indication of interest as well as other, customary transaction terms.

In early May, Byline indicated that it would require the disposition or winding down of Inland’s mortgage banking business. Inland began evaluating different alternatives to dispose of, or wind down its mortgage operations. Through Piper Sandler, Inland reached out to potential parties who may have had interest in purchasing the mortgage business. In addition, the Inland management team reached out to one additional party directly. After several weeks of outreach to find a potential partner to purchase the mortgage business, including serious discussions with one such party, Inland’s management team concluded that it was not feasible to sell the mortgage business and determined that it would wind down the business, regardless of a strategic transaction, given the current economic environment involving the home-mortgage business.

After engaging in due diligence and preliminary negotiations for approximately two (2) months, on or about May 18, 2022, Byline’s management informed Inland that Byline was not going to continue to pursue a transaction with Inland at that time. Byline’s management indicated that its board wanted to evaluate the overall economic situation, including the interest rate environment and the impact of a possible recession, before committing to moving forward with a transaction.

The indication of interest originally signed by the parties provided for an exclusivity period through May 2, 2022 during which Inland could not engage in discussions regarding a strategic transaction with any party other than Byline. After May 18, 2022, with Byline’s indication that it was not in a position to commit to a transaction with Inland at that time, Inland’s management team instructed Piper Sandler to approach other financial institutions, including credit unions headquartered in the Midwest, to evaluate whether there was interest in pursuing a transaction with Inland. During the period from May through July 2022, Piper Sandler had discussions with other financial institutions, including credit unions and several of the other traditional banking institutions who were previously approached in early 2022. Following those discussions, Inland entered into a confidentiality agreement with one other financial institution. This party did not present an indication of interest for a transaction with Inland that was as favorable for Inland and its stockholders as the financial and other terms originally set forth by Byline.

In August 2022, Byline and Inland re-engaged negotiations and entered into a letter agreement providing for further negotiation between the parties with the goal of moving toward a transaction on the same general financial and transactional terms originally set forth in the March non-binding indication of interest. The parties agreed to re-establish an exclusivity arrangement pursuant to which Inland would negotiate exclusively with Byline through October 7, 2022.

Over the next several weeks, the parties re-engaged with due diligence and held multiple discussions regarding working toward a definitive agreement and plan of merger. On August 24, 2022, Byline’s counsel, Vedder Price P.C., sent an initial draft of the merger agreement to Barack Ferrazzano Kirschbaum & Nagelberg LLP.

Through the remainder of September and October of 2022, the parties continued to negotiate the material terms of the proposed transaction and exchanged drafts of the merger agreement and certain related ancillary documents, including the form of voting agreement. The parties negotiated, among other items, the representations and warranties that would be made by Inland and Byline, the possible change in consideration based on Inland’s tangible equity at the time of closing, certain closing requirements, including the disposition of the mortgage business and certain other assets, termination rights and other

TABLE OF CONTENTS

terms. The parties continued conducting due diligence, including reverse due diligence on Byline, through this period. This process included discussions with Byline’s management team with legal and financial advisors present.

On October 27, 2022, the parties agreed to further extend the exclusivity period through November 11, 2022. As a result, throughout November, 2022, Byline continued to perform additional confirmatory diligence on Inland and its operations. In addition, the parties continued to negotiate the terms of the draft definitive merger agreement, disclosure schedules and ancillary agreements.

On November 14, 2022, the Inland board held a special meeting to consider the proposed merger with Byline, including the merger consideration, which, in the aggregate, was approximately 87% shares of Byline common stock and 13% cash, resulting in an implied value of $5.06 per share of Inland common stock, or $170.9 million in the aggregate, based on the closing price of Byline common stock on November 11, 2022. The Inland board also carefully considered the other transaction terms which had been negotiated over the past several months. At the meeting, representatives of Barack Ferrazzano Kirschbaum & Nagelberg LLP delivered a presentation regarding the fiduciary duties of the Inland board in connection with the proposed transaction. Inland’s management also reported on, and the Inland board discussed, the reverse due diligence process undertaken by Inland with respect to Byline. During the meeting, Piper Sandler reviewed the financial aspects of the proposed merger and rendered to the Inland board an opinion to the effect that, as of such date and subject to the procedures followed, assumptions made, matters considered and qualifications and limitations on the review undertaken by Piper Sandler as set forth in its opinion, the merger consideration in the proposed merger was fair, from a financial point of view, to the holders of Inland common stock. After discussion and after considering the proposed terms of the transaction documents, and taking into account the strategic rationale, financial terms, consideration to be received by Inland stockholders, integration risk and business rationale of consummating a merger with Byline, including the factors described in the section titled “— Recommendation of the Inland Board of Directors and Inland’s Reasons for the Merger,” the Inland board, having determined that the terms of the merger agreement and the transactions contemplated thereby, including the merger, were fair to and in the best interests of Inland and its stockholders, unanimously approved and declared advisable the merger agreement and the transactions contemplated thereby. The Inland board authorized senior management to finalize the transaction documents and to execute the documents, including the merger agreement. The Inland board directed that the merger agreement be submitted to holders of Inland’s common stock for approval, and recommended that holders of Inland common stock vote in favor of the adoption of the merger agreement and the approval of the transactions contemplated thereby.

On November 9, 2022, an executive committee of the board of directors of Byline held a meeting to consider the terms of the proposed acquisition of Inland. Subsequently, on November 18, 2022, the full Byline board met to consider the terms of the proposed transaction. At the meeting, members of the Byline board and senior management discussed the strategic and business rationale of consummating an acquisition of Inland, including the factors described in the section titled “— Byline’s Reasons for the Merger”. Members of Byline’s senior management also reported on the results of their due diligence of Inland. Also at this meeting, Byline’s financial advisor, Stephens, Inc., reviewed with the Byline board the financial aspects of the proposed transaction, and rendered an opinion to the Byline board (which was initially rendered verbally and confirmed in a written opinion, dated November 30, 2022), that based upon and subject to the limitations, assumptions and qualifications set forth in the written opinion, that the consideration to be given by Byline in the proposed transaction is fair to Byline from a financial point of view.

Following those discussions and presentations by Byline’s senior management, and after further deliberations among members of the Byline board, the Byline board determined that the merger, the merger agreement and the transactions contemplated by the merger agreement were advisable and in the best interests of Byline and its stockholders, and the directors voted unanimously to approve the merger and to approve and adopt the merger agreement.

Through the remainder of November 2022, the parties worked to finalize the agreement and plan of merger and ancillary documents and to organize the communication plan for the transaction. On November 30, 2022, the merger agreement and related documents were signed by the parties and Byline announced the transaction via a press release.

TABLE OF CONTENTS

Recommendation of the Inland Board of Directors and Inland’s Reason’s for the Merger

After careful consideration, the Inland board, at a meeting held on November 14, 2022, unanimously determined that the merger agreement and the transactions contemplated by the merger agreement were advisable and in the best interests of Inland and its stockholders and approved the merger agreement and the transactions contemplated by the merger agreement, including the merger. Accordingly, the Inland board recommends that Inland stockholders vote “FOR” approval and adoption of the merger agreement at the Inland special meeting.

In reaching its decision, the Inland board, with advice from its financial and legal advisors, considered a number of factors, including the following:

•

Inland board’s knowledge of Inland’s business, results of operations, financial condition, competitive position and future prospects, and the results of operations, financial condition, competitive position and future prospects of Byline, taking into account the results of Inland’s due diligence review of Byline and information provided by Inland’s financial advisor;

•

Inland board’s knowledge of the current environment in the financial services industry, including national, regional and local economic conditions and trends with respect to bank mergers and acquisitions and pricing for such transactions;

•

the opportunity for Inland stockholders to have increased liquidity upon receipt of the Byline common stock portion of the merger consideration, in exchange for their Inland common stock, because Inland is a private company with no public trading market for its shares whereas Byline common stock is listed on the NYSE under the symbol “BY”;

•

the fact that the Byline common stock portion of the merger consideration would allow Inland stockholders who receive Byline common stock to participate in the future performance of the combined Inland and Byline businesses and potential synergies resulting from the merger, and the potential future value to Inland stockholders represented by that consideration;

•

the opportunity for Inland stockholders to have liquidity upon receipt of the cash portion of the merger consideration, as well as certainty of value of the cash consideration upon closing of the merger;

•

the expectation that receipt by the Inland stockholders of the Byline common stock portion of the merger consideration will not be a taxable event, and any tax liability will be deferred until an Inland stockholder otherwise engages in a taxable transaction with respect to the Byline common stock received;

•

Inland board’s belief that the merger would have a positive effect on Inland Bank’s depositors, customers and the communities served by Inland Bank, as a result of the combined company’s ability to provide additional and expanded products and services to these customers, and that this would have a positive impact on the future operating results of the combined company;

•

the potential strategic alternatives available to Inland, the possibility of remaining a stand-alone entity, and the increased regulatory, IT, accounting and administrative expenses as a result of Inland’s continued growth;

•

Inland’s and Byline’s respective sizes, businesses, operations, financial condition, asset quality, earnings and prospects, including the strong deposit base and regulatory capital ratios of Byline Bank;

•

the complementary aspects of Byline’s and Inland’s businesses, including customer focus, geographic coverage, business orientation and operations, Byline’s strengths in specialty and SBA lending, Byline Bank’s strong deposit market share and Byline Bank’s strengths in relationship- based commercial lending;

•

Inland board’s view, based on consultation with its financial advisor, that the merger consideration represents a premium to the implied value of the Inland common stock;

•

the financial analyses presented by Piper Sandler to the Inland board and the verbal opinion of Piper Sandler (which was subsequently confirmed in writing by delivery of Piper Sandler’s written

TABLE OF CONTENTS

opinion dated November 14, 2022) to the effect that, as of such date, and based upon and subject to the assumptions, considerations, qualifications and limitations set forth in the written opinion, the merger consideration to be received by holders of Inland common stock pursuant to the merger was fair, from a financial point of view, to those stockholders. For more information, see the section titled “— Opinion of Inland’s Financial Advisor” in this proxy statement/prospectus;

•

that both the exchange ratio and the cash consideration are subject to possible upward and downward adjustment in the event that the Inland closing tangible common equity is greater or less than the Inland minimum tangible common equity;

•

the experience and successful track record of Byline’s management team in acquiring and integrating financial institutions;

•

the fact that the Inland board was not aware of facts or circumstances as of the date of its recommendation suggesting the merger would fail to be approved by the relevant bank regulatory authorities in a timely manner, or that the relevant bank regulatory authorities would seek to impose a burdensome condition on their respective approvals of the merger;

•

the right of the Inland stockholders to exercise dissenters’ rights (as more fully described in section titled “The Merger — Dissenters’ Rights” in this proxy statement/prospectus);

•

the financial and other terms of the merger agreement, which were the product of arms-length negotiations between the parties;

•

the fact that the Inland board is permitted to change its recommendation that Inland stockholders approve the merger agreement in certain circumstances;

•

the risks that certain of the conditions to the consummation of the merger set forth in the merger agreement are not satisfied in a timely manner, or at all;

•

the risks associated with the operation of the combined company, including the challenges both of integrating Inland’s business, operations and employees with those of Byline, and of achieving the anticipated synergies and cost savings associated with the merger;

•

the potential risk of diverting management focus and resources from other strategic opportunities and from operational matters while working to implement the merger, including the restrictions on the conduct of Inland’s business prior to completion of the merger;

•

the fact that the directors and certain officers of Inland have interests in the merger that are different from or in addition to those of Inland stockholders generally; and

•

the fact that the integrated merger is intended to qualify for federal income tax purposes as a reorganization under Section 368(a) of the Code.

The reasons set forth above are not intended to be exhaustive, but a summary of the material factors considered by the Inland board in approving the merger agreement. Although each member of the Inland board individually considered these and other factors, the Inland board did not collectively assign any specific or relative weights to the factors considered and did not make any determination with respect to any individual factor. The Inland board collectively made its determination with respect to the merger based on the conclusion reached by its members, in light of the factors that each of them considered appropriate, that the merger is in the best interests of Inland and its stockholders. The Inland board realized that there can be no assurance about future results, including results expected or considered in the factors listed above. The Inland board concluded, however, including based on discussions with senior management and its financial and legal advisors, that the potential positive factors outweighed the potential risks of entering into the merger agreement.

The foregoing discussion of the information and factors considered by the Inland board is forward- looking in nature and this information should be read in light of the factors described under the section titled “Cautionary Statement Regarding Forward-Looking Statements” in this proxy statement/ prospectus.

Opinion of Inland’s Financial Advisor

Inland retained Piper Sandler to act as financial advisor to Inland’s board of directors in connection with Inland’s consideration of a possible business combination. Inland selected Piper Sandler to act as its

TABLE OF CONTENTS

financial advisor because Piper Sandler is a nationally recognized investment banking firm. In the ordinary course of its investment banking business, Piper Sandler is regularly engaged in the valuation of financial institutions and their securities in connection with mergers and acquisitions and other corporate transactions.

Piper Sandler acted as financial advisor to Inland’s board of directors in connection with the proposed merger and participated in certain of the negotiations leading to the execution of the merger agreement. At the November 14, 2022 meeting at which Inland’s board of directors considered the merger and the merger agreement, Piper Sandler delivered to the board of directors its oral opinion, which was subsequently confirmed in writing on November 14, 2022, to the effect that, as of such date, the merger consideration was fair to the holders of Inland’s common stock from a financial point of view. The full text of Piper Sandler’s opinion is attached as Appendix C to this preliminary proxy statement/prospectus. The opinion outlines the procedures followed, assumptions made, matters considered and qualifications and limitations on the review undertaken by Piper Sandler in rendering its opinion. The description of the opinion set forth below is qualified in its entirety by reference to the full text of the opinion. Holders of Inland common stock are urged to read the entire opinion carefully in connection with their consideration of the proposed merger.

Piper Sandler’s opinion was directed to the board of directors of Inland in connection with its consideration of the merger and the merger agreement and does not constitute a recommendation to any shareholder of Inland as to how any such shareholder should vote at any meeting of shareholders called to consider and vote upon the approval of the merger and the merger agreement. Piper Sandler’s opinion was directed only to the fairness, from a financial point of view, of the merger consideration to the holders of Inland common stock and did not address the underlying business decision of Inland to engage in the merger, the form or structure of the merger or any other transactions contemplated in the merger agreement, the relative merits of the merger as compared to any other alternative transactions or business strategies that might exist for Inland or the effect of any other transaction in which Inland might engage. Piper Sandler also did not express any opinion as to the fairness of the amount or nature of the compensation to be received in the merger by any officer, director or employee of Inland or Byline, or any class of such persons, if any, relative to the compensation to be received in the merger by any other shareholder. Piper Sandler’s opinion was approved by Piper Sandler’s fairness opinion committee.

In connection with its opinion, Piper Sandler reviewed and considered, among other things:

•

a draft of the merger agreement, dated November 8, 2022;

•

certain publicly available financial statements and other historical financial information of Inland and its banking subsidiary, Inland Bank & Trust, that Piper Sandler deemed relevant;

•

certain publicly available financial statements and other historical financial information of Byline that Piper Sandler deemed relevant;

•

certain internal financial projections for Inland for the years ending December 31, 2022 through December 31, 2026, as provided by the senior management of Inland;

•

publicly available median analyst earnings per share estimates for Byline for the years ending December 31, 2022 through December 31, 2024 with an annual long-term earnings per share and balance sheet growth rate for Byline for the years ending December 31, 2025 and December 31, 2026, as well as publicly available consensus analyst estimated dividends per share for the years ending December 31, 2022 through December 31, 2024 with an annual dividend growth rate for the years ending December 31, 2025 and December 31, 2026, as provided by the senior management of Byline;

•

the pro forma financial impact of the merger on Byline based on certain assumptions relating to transaction expenses, purchase accounting adjustments and cost savings, as well as the establishment of certain reserves for current expected credit losses (CECL) accounting standards, as provided by the senior management of Byline;

•

the publicly reported historical price and trading activity for Byline common stock, including a comparison of certain stock trading information for Byline common stock and certain stock indices, as well as similar publicly available information for certain other companies, the securities of which are publicly traded;

TABLE OF CONTENTS

•

a comparison of certain financial and market information for Inland and Byline with similar financial institutions for which information is publicly available;

•

the financial terms of certain recent business combinations in the bank and thrift industry (on a nationwide basis), to the extent publicly available;

•

the current market environment generally and the banking environment in particular; and

•

such other information, financial studies, analyses and investigations and financial, economic and market criteria as Piper Sandler considered relevant.

Piper Sandler also discussed with certain members of the senior management of Inland and its representatives the business, financial condition, results of operations and prospects of Inland and held similar discussions with certain members of the senior management of Byline and its representatives regarding the business, financial condition, results of operations and prospects of Byline.

In performing its review, Piper Sandler relied upon the accuracy and completeness of all financial and other information that was available to and reviewed by Piper Sandler from public sources, that was provided to Piper Sandler by Inland or Byline or their respective representatives, or that was otherwise reviewed by Piper Sandler, and Piper Sandler assumed such accuracy and completeness for purposes of rendering its opinion without any independent verification or investigation. Piper Sandler relied on the assurances of the respective managements of Inland and Byline that they were not aware of any facts or circumstances that would have made any of such information inaccurate or misleading. Piper Sandler was not asked to and did not undertake an independent verification of any of such information and Piper Sandler did not assume any responsibility or liability for the accuracy or completeness thereof. Piper Sandler did not make an independent evaluation or perform an appraisal of the specific assets, the collateral securing assets or the liabilities (contingent or otherwise) of Inland or Byline, nor was Piper Sandler furnished with any such evaluations or appraisals. Piper Sandler rendered no opinion or evaluation on the collectability of any assets or the future performance of any loans of Inland or Byline. Piper Sandler did not make an independent evaluation of the adequacy of the allowance for loan losses of Inland or Byline, or of the combined entity after the merger, and Piper Sandler did not review any individual credit files relating to Inland or Byline. Piper Sandler assumed, with Inland’s consent, that the respective allowances for loan losses for both Inland and Byline were adequate to cover such losses and would be adequate on a pro forma basis for the combined entity.

In preparing its analyses, Piper Sandler used certain internal financial projections for Inland for the years ending December 31, 2022 through December 31, 2026, as provided by the senior management of Inland. In addition, Piper Sandler used publicly available median analyst earnings per share estimates for Byline for the years ending December 31, 2022 through December 31, 2024 with an annual long-term earnings per share and balance sheet growth rate for Byline for the years ending December 31, 2025 and December 31, 2026, as well as publicly available consensus analyst estimated dividends per share for the years ending December 31, 2022 through December 31, 2024 with an annual dividend growth rate for the years ending December 31, 2025 and December 31, 2026, as provided by the senior management of Byline. Piper Sandler also received and used in its pro forma analyses certain assumptions relating to transaction expenses, purchase accounting adjustments and cost savings, as well as the establishment of certain reserves for CECL accounting standards, as provided by the senior management of Byline. With respect to the foregoing information, the respective senior managements of Inland and Byline confirmed to Piper Sandler that such information reflected (or, in the case of the publicly available median analyst estimates referred to above, were consistent with) the best currently available projections, estimates and judgments of those respective managements as to the future financial performance of Inland and Byline, respectively, and the other matters covered thereby, and Piper Sandler assumed that the future financial performance reflected in such information would be achieved. Piper Sandler expressed no opinion as to such information, or the assumptions on which such information was based. Piper Sandler also assumed that there had been no material change in the respective assets, financial condition, results of operations, business or prospects of Inland or Byline since the date of the most recent financial statements made available to Piper Sandler. Piper Sandler assumed in all respects material to its analyses that Inland and Byline would remain as going concerns for all periods relevant to its analyses.

TABLE OF CONTENTS

Piper Sandler assumed for purposes of its analyses, at Inland’s direction and with Inland’s consent, that Inland’s Tangible Common Equity as set forth in the Final Closing Balance Sheet (i) would not be less than $134,500,000.00, and therefore the Cash Consideration would not be reduced, and (ii) would not be greater than $140,500,000.00, and therefore that the Cash Consideration would not be increased. Piper Sandler also assumed, with Inland’s consent, that (i) each of the parties to the merger agreement would comply in all material respects with all material terms and conditions of the merger agreement and all related agreements, that all of the representations and warranties contained in such agreements were true and correct in all material respects, that each of the parties to such agreements would perform in all material respects all of the covenants and other obligations required to be performed by such party under such agreements and that the conditions precedent in such agreements were not and would not be waived, (ii) in the course of obtaining the necessary regulatory or third party approvals, consents and releases with respect to the merger, no delay, limitation, restriction or condition would be imposed that would have an adverse effect on Inland, Byline, the merger or any related transactions, and (iii) the merger and any related transactions would be consummated in accordance with the terms of the merger agreement without any waiver, modification or amendment of any material term, condition or agreement thereof and in compliance with all applicable laws and other requirements. Finally, with Inland’s consent, Piper Sandler relied upon the advice that Inland received from its legal, accounting and tax advisors as to all legal, accounting and tax matters relating to the merger and the other transactions contemplated by the merger agreement. Piper Sandler expressed no opinion as to any such matters.

Piper Sandler’s opinion was necessarily based on financial, economic, regulatory, market and other conditions as in effect on, and the information made available to Piper Sandler as of, the date thereof. Events occurring after the date thereof could materially affect Piper Sandler’s opinion. Piper Sandler has not undertaken to update, revise, reaffirm or withdraw its opinion or otherwise comment upon events occurring after the date thereof. Piper Sandler expressed no opinion as to the trading value of Byline common stock at any time or what the value of Byline common stock would be once it is actually received by the holders of Inland common stock.

In rendering its opinion, Piper Sandler performed a variety of financial analyses. The summary below is not a complete description of all the analyses underlying Piper Sandler’s opinion or the presentation made by Piper Sandler to Inland’s board of directors, but is a summary of the material analyses performed and presented by Piper Sandler. The summary includes information presented in tabular format. In order to fully understand the financial analyses, these tables must be read together with the accompanying text. The tables alone do not constitute a complete description of the financial analyses. The preparation of a fairness opinion is a complex process involving subjective judgments as to the most appropriate and relevant methods of financial analysis and the application of those methods to the particular circumstances. The process, therefore, is not necessarily susceptible to a partial analysis or summary description. Piper Sandler believes that its analyses must be considered as a whole and that selecting portions of the factors and analyses to be considered without considering all factors and analyses, or attempting to ascribe relative weights to some or all such factors and analyses, could create an incomplete view of the evaluation process underlying its opinion. Also, no company included in Piper Sandler’s comparative analyses described below is identical to Inland or Byline and no transaction is identical to the merger. Accordingly, an analysis of comparable companies or transactions involves complex considerations and judgments concerning differences in financial and operating characteristics of the companies and other factors that could affect the public trading values or transaction values, as the case may be, of Inland and Byline and the companies to which they were compared. In arriving at its opinion, Piper Sandler did not attribute any particular weight to any analysis or factor that it considered. Rather, Piper Sandler made qualitative judgments as to the significance and relevance of each analysis and factor. Piper Sandler 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, Piper Sandler made its determination as to the fairness of the merger consideration to the holders of Inland common stock on the basis of its experience and professional judgment after considering the results of all its analyses taken as a whole.

In performing its analyses, Piper Sandler also made numerous assumptions with respect to industry performance, business and economic conditions and various other matters, many of which cannot be predicted and are beyond the control of Inland, Byline, and Piper Sandler. The analyses performed by Piper Sandler are not necessarily indicative of actual values or future results, both of which may be significantly

TABLE OF CONTENTS

more or less favorable than suggested by such analyses. Piper Sandler prepared its analyses solely for purposes of rendering its opinion and provided such analyses to Inland’s board of directors at its November 14, 2022 meeting. Estimates on the values of companies do not purport to be appraisals or necessarily reflect the prices at which companies or their securities may actually be sold. Such estimates are inherently subject to uncertainty and actual values may be materially different. Accordingly, Piper Sandler’s analyses do not necessarily reflect the value of Inland common stock or Byline common stock or the prices at which Inland or Byline common stock may be sold at any time. The analyses of Piper Sandler and its opinion were among a number of factors taken into consideration by Inland’s board of directors in making its determination to approve the merger agreement and the analyses described below should not be viewed as determinative of the decision of Inland’s board of directors with respect to the fairness of the merger consideration.

Summary of Proposed Merger Consideration and Implied Transaction Metrics

Piper Sandler reviewed the financial terms of the proposed merger. Based on information contained in the draft merger agreement, dated November 8, 2022, at the effective time of the merger each share of Inland common stock issued and outstanding immediately prior to the effective time of the transaction, except for certain shares as set forth in the merger agreement, shall be converted into the right to receive the following: (i) such number of fully paid and non-assessable shares of Byline common stock equal to the quotient obtained by dividing (A) 6,388,781 by (B) the number of shares of Inland common stock issued and outstanding immediately prior to the Effective Time (the “Exchange Ratio”); provided that in the event that the total number of issued and outstanding shares of Inland common stock at Closing is less than 33,625,162, then the Exchange Ratio shall be equal to 0.19; and (ii) a cash payment in the amount equal to the quotient obtained by dividing (A) $22,865,110.20 by (B) the number of shares of Inland common stock issued and outstanding immediately prior to the Effective Time (the “Cash Consideration”), subject to any adjustment as set forth in the merger agreement; provided that in the event that the total number of issued and outstanding shares of Inland common stock at Closing is less than 33,625,162, then the Cash Consideration shall be equal to $0.68. Piper Sandler calculated an aggregate implied transaction value of approximately $170,190,395 and an implied purchase price per share of $5.06 consisting of the implied value of 33,625,162 shares of Inland common stock and 295,200 Inland options outstanding with a weighted average strike price of $2.65 and based on the closing price of Byline common stock on November 11, 2022. Based upon financial information for Inland as of or for the last twelve months (“LTM”) ended September 30, 2022, Piper Sandler calculated the following implied aggregate transaction metrics:

	Aggregate Transaction Price / Book Value					130%
	Aggregate Transaction Price / Tangible Book Value					130%
	Aggregate Transaction Price / LTM Earnings					24.6x
	Aggregate Transaction Price / Estimated 2022 Earnings(1)					22.1x
	Aggregate Transaction Price / Estimated 2023 Earnings(1)					14.2x
	Core Deposit Premium(2)					4.2%
	Core Deposit Premium(3)					3.9%

Net Present Value Analyses

Piper Sandler performed an analysis that estimated the net present value of a share of Inland common stock assuming Inland performed in accordance with certain internal financial projections for Inland for the years ending December 31, 2022 through December 31, 2026, as provided by the senior management of Inland. To approximate the terminal value of a share of Inland common stock at December 31, 2026, Piper Sandler applied price to 2026 earnings multiples ranging from 8.0x to 13.0x and multiples of December 31, 2026 tangible book value ranging from 80% to 130%. The terminal values were then discounted to present values using different discount rates ranging from 11.0% to 15.0%, which were chosen to reflect different assumptions regarding required rates of return of holders or prospective buyers of Inland common stock. As illustrated in the following tables, the analysis indicated an imputed range of values per share of Inland common stock of $1.84 to $3.48 when applying multiples of earnings and $2.47 to $4.67 when applying multiples of tangible book value.

Piper Sandler also considered and discussed with the Inland board of directors how this analysis would be affected by changes in the underlying assumptions, including variations with respect to earnings. To illustrate this impact, Piper Sandler performed a similar analysis, assuming Inland’s earnings varied from 15% above projections to 15% below projections. This analysis resulted in the following range of per share values for Inland common stock, applying the price to 2026 earnings multiples range of 8.0x to 13.0x referred to above and a discount rate of 12.36%.

Piper Sandler also performed an analysis that estimated the net present value per share of Byline common stock, assuming Byline performed in accordance with publicly available median analyst earnings per share estimates for Byline for the years ending December 31, 2022 through December 31, 2024 with an annual long-term earnings per share and balance sheet growth rate for Byline for the years ending December 31, 2025 and December 31, 2026, as well as publicly available consensus analyst estimated dividends per share for the years ending December 31, 2022 through December 31, 2024 with an annual dividend growth rate for the years ending December 31, 2025 and December 31, 2026, as provided by the senior management of Byline. To approximate the terminal value of a share of Byline common stock at December 31, 2026, Piper Sandler applied price to 2026 earnings multiples ranging from 8.0x to 13.0x and multiples of December 31, 2026 tangible book value ranging from 140% to 190%. The terminal values were then discounted to present values using different discount rates ranging from 9.0% to 13.0%, which were chosen to reflect different assumptions regarding required rates of return of holders or prospective buyers of Byline common stock. As illustrated in the following tables, the analysis indicated an imputed range of values per share of Byline common stock of $13.81 to $25.11 when applying multiples of earnings and $21.47 to $33.32 when applying multiples of tangible book value.

Piper Sandler noted that the net present value analysis is a widely used valuation methodology, but the results of such methodology are highly dependent upon the numerous assumptions that must be made, and the results thereof are not necessarily indicative of actual values or future results.

Pro Forma Transaction Analysis

Piper Sandler analyzed certain potential pro forma effects of the merger on Byline assuming the transaction closes March 31, 2023. Piper Sandler utilized the following information and assumptions: (a) certain internal financial projections for Inland for the years ending December 31, 2022 through December 31, 2026, as provided by the senior management of Inland, (b) publicly available median analyst earnings per share estimates for Byline for the years ending December 31, 2022 through December 31, 2024 with an annual long-term earnings per share and balance sheet growth rate for Byline for the years ending December 31, 2025 and December 31, 2026, as well as publicly available consensus analyst estimated dividends per share for the years ending December 31, 2022 through December 31, 2024 with an annual dividend growth rate for the years ending December 31, 2025 and December 31, 2026, as provided by the senior management of Byline, and (c) certain assumptions relating to transaction expenses, purchase accounting adjustments and cost savings, as well as the establishment of certain reserves for CECL accounting standards, as provided by the senior management of Byline. The analysis indicated that the merger could be accretive to Byline’s estimated earnings per share (excluding one-time transaction costs and expenses) in the years ending December 31, 2023 through December 31, 2026 and dilutive to Byline’s estimated tangible book value per share at closing.

In connection with this analysis, Piper Sandler considered and discussed with the Inland board of directors how the analysis would be affected by changes in the underlying assumptions, including the impact of final purchase accounting adjustments determined at the closing of the transaction, and noted that the actual results achieved by the combined company may vary from projected results and the variations may be material.

Piper Sandler’s Relationship

Piper Sandler is acting as Inland’s financial advisor in connection with the transaction and will receive a fee for such services in an amount equal to 1.25% of the aggregate purchase price plus 1.00% of the amount by which the aggregate purchase price exceeds $202.0 million, if any, which fee is contingent upon the closing of the merger. At the time of announcement of the merger Piper Sandler’s fee was approximately $2,059,500. Piper Sandler also received a $250,000 fee from Inland upon rendering its opinion, which opinion fee will be credited in full towards the advisory fee which will become payable to Piper Sandler upon closing of the merger. Inland has also agreed to indemnify Piper Sandler against certain claims and liabilities arising out of Piper Sandler’s engagement and to reimburse Piper Sandler for certain of its out-of-pocket expenses incurred in connection with Piper Sandler’s engagement.

TABLE OF CONTENTS

Piper Sandler did not provide any other investment banking services to Inland in the two years preceding the date of Piper Sandler’s opinion. Piper Sandler did not provide any investment banking services to Byline in the two years preceding the date of its opinion. In the ordinary course of Piper Sandler’s business as a broker-dealer, Piper Sandler may purchase securities from and sell securities to Inland, Byline and their respective affiliates. Piper Sandler may also actively trade the equity and debt securities of Byline and its affiliates for Piper Sandler’s account and for the accounts of Piper Sandler’s customers.

Byline’s Reasons for the Merger

In reaching its decision to approve the merger agreement, the merger and the other transactions contemplated by the merger agreement, the Byline board consulted with Byline senior management, as well as its financial and legal advisors, and considered a number of factors, including the following material factors:

•

each of Byline’s, Inland’s, and the combined company’s business, operations, financial condition, asset quality, earnings and prospects, including the belief that Inland’s financial condition, asset quality and underwriting procedures are sound, that Inland’s business, operations and geographic footprint would complement those of Byline and allow it to expand its franchise into the Western and Northwestern suburban Chicago markets, and that the merger would result in a combined company with a larger market presence and more attractive funding base, including through low cost core deposit funding, than Byline on a stand-alone basis;

•

the opportunity to add a significant, low-cost core deposit portfolio that would increase Byline’s deposit market share in both the State of Illinois and the Chicago MSA;

•

the opportunities for growth through the ability to offer Byline Bank’s broader range of products and services to Inland’s customers;

•

anticipated efficiencies to come from integrating Inland’s operations into Byline’s existing operations;

•

the financial terms of the transaction, including the expectation that the transaction would be accretive to Byline’s earnings per share in the first full year with the expected cost savings, provide manageable tangible book value dilution at closing inclusive of transaction expenses, allow Byline to continue to maintain strong capital levels post-closing, and that the exchange ratio applicable to the portion of the merger consideration payable in shares of Byline common stock is not subject to automatic adjustment as a result of changes in the market value of Byline common stock, limiting the risk of further dilution to Byline’s existing stockholders if the trading price of Byline common stock were to decrease;

•

management’s experience and successful track record with acquiring and integrating financial institutions;

•

the view that Inland’s relationship-oriented commercial banking business would be complementary, and is compatible with Byline and its subsidiaries;

•

a review of the demographic, economic and financial characteristics of the markets in which Inland operates, including existing and potential competition and history of the market area with respect to financial institutions;

•

its review and discussions with Byline’s management, legal counsel and tax advisors concerning the due diligence investigation of Inland conducted by Byline;

•

the opportunity to build a greater recognition and awareness of the Byline brand; and

•

the belief that the merger would be approved by the relevant bank regulatory authorities without undue burden and in a timely manner.

In addition, the Byline board considered a number of risks with respect to the merger, including the following:

•

that the exchange ratio applicable to the portion of the merger consideration payable in shares of Byline common stock is not subject to adjustment as a result of changes in the market value of Byline

TABLE OF CONTENTS

common stock, and the resulting risk that the value of the merger consideration payable to Inland common stockholders could increase if the trading price of Byline common stock were to increase;

•

the potential risks associated with achieving anticipated cost synergies and savings and successfully integrating Inland’s business, operations and workforce with those of Byline, including the transaction costs that would be incurred in connection with the transaction;

•

the potential risk of diverting management attention and resources from the operation of Byline’s business towards the completion of the merger and other integration efforts;

•

that Byline would not be entitled to indemnification for certain losses it could incur in connection with the transaction;

•

uncertainties regarding developments in accounting, federal and state income tax and bank regulatory policy; and

•

the other risks identified under “Risk Factors” and “Cautionary Statement Regarding Forward- Looking Statements”.

The foregoing discussion of the information and factors considered by the Byline board is not intended to be exhaustive, but includes the material factors considered by the Byline. In reaching its decision to approve the merger agreement, the merger and the other transactions contemplated by the merger agreement, the Byline board did not quantify or assign any relative weights to the factors considered, and individual directors may have given different weights to different factors. The Byline board considered all these factors as a whole and overall considered the factors to be favorable to, and to support its determination to approve, entering into the merger agreement.

This explanation of Byline’s reasons for the merger and other information presented in this section is forward-looking in nature and should be read in light of the section entitled “Cautionary Statement Regarding Forward-Looking Statements”.

The Byline board realized that there can be no assurance about future results, including results expected or considered in the factors listed above, such as assumptions regarding enhanced business prospects, anticipated cost savings and earnings accretion/dilution. The Byline board concluded, however, that the potential positive factors outweighed the potential risks of completing the transaction.

Management and Board of Directors of Byline After the Merger

Prior to the effective time to be effective at the effective time, Byline has agreed to appoint one person, mutually agreed upon by both Inland and Byline, as a director to Byline Bancorp’s board and to re-nominate such person as a director for a one-year term at each of Byline’s annual meeting of stockholders to be held in 2023 and 2024. If, during this period, such person for any reason ceases to serve as a director or choses for any reason not to stand for re-election, Byline’s board will promptly appoint another person, as mutually agreed upon by Inland and Byline. However, in the event that, at any time during this period, Mr. Goodwin’s beneficial ownership of Byline common stock falls below five percent (5%) of the then outstanding shares of Byline common stock, Byline may, but will not be required to, choose not to re-nominate the person then serving on Byline’s board at the next annual meeting of stockholders.

Other than as described above, the directors and officers of Byline immediately prior to the effective time will be the directors and officers of Byline after the consummation of the merger and parent merger, and will serve until such time as their successors are duly elected and qualified.

Interests of Inland Directors and Executive Officers in the Merger

The transactions contemplated by the merger agreement also include certain other agreements relating to employment matters of certain executive officers and other employees of Inland previously entered into, or to be entered into, in connection with the merger.

In considering the recommendation of the Inland board, Inland stockholders should be aware that the directors, executive officers and other employees of Inland have certain interests in the merger that may be different from, or in addition to, the interests of Inland stockholders generally. The Inland board was aware

TABLE OF CONTENTS

of these interests and considered them, among other matters, in making its recommendation that Inland stockholders vote to approve the merger proposal. These interests are described in further detail below.

Treatment of Options to Acquire Inland Common Stock

Each Inland stock option that is outstanding immediately prior to the effective time will be cancelled in exchange for a cash payment equal to the product of (A) the difference between (i) the sum of (x) the product of the exchange ratio multiplied by the volume weighted average price of one share of Byline common stock as reported on the NYSE for the five (5) business days ending on the business day immediately prior to the closing date (which we refer to as the Byline closing price) plus (y) the cash consideration, less (ii) the exercise price per share of Inland common stock under such stock option, multiplied by (B) the number of shares of Inland common stock covered by such stock option (an “Option Payment”). In order to receive the Option Payment, each Inland stock option holder must execute and submit to Inland an option termination agreement which includes a full release of any claims related to such options against Inland and Inland Bank.

Existing Employment Agreements and Change in Control Agreements

Certain executive officers of Inland Bank previously entered into employment agreements or change in control agreements with Inland Bank. Specifically, Peter Stickler, President and CEO of Inland Bank, entered into an employment agreement with Inland Bank pursuant to which he will receive a change in control payment of $2,055,360 upon closing of the merger. Deborah Bartelt, Executive Vice President of Inland Bank, entered into an employment agreement with Inland Bank pursuant to which she will receive a change in control payment of $893,241 upon closing of the transaction. In addition, each of Paul Berley, Chief Financial Officer of Inland Bank, and Dan Healy, Executive Vice President of Inland Bank, entered into change in control agreements with Inland Bank and will receive a change in control payment of $243,750 and $252,450, respectively, upon closing of the merger.

Retention Agreements with Other Officers

In addition, Inland Bank has previously entered into retention agreements with certain executive officers and other employees pursuant to which each such employee is entitled to receive a retention cash bonus award. The aggregate amount of retention awards payable to such employees will not exceed $1,178,690. To the extent not already paid, such awards will be payable on the next regularly scheduled payroll date following the closing date or the bank conversion date, as applicable; provided that the applicable employee remains employed through the date of payment.

Indemnification; Directors’ and Officers’ Insurance

Following the effective time, to the extent permitted by applicable law and to the same extent as provided by Inland under its charter documents at the time of the merger agreement, Byline has agreed to indemnify, hold harmless, and advance expenses to the current and former directors, officers and employees of Inland and its subsidiaries for actions taken by them in their position as a director, officer or employee of Inland or its subsidiaries prior to the effective time.

Regulatory Approvals Required for the Merger

Consummation of the merger is subject to several federal and state regulatory agency filings and approvals. The merger and the bank merger cannot be completed unless and until Byline and Byline Bank, on the one hand, and Inland and Inland Bank, on the other hand, have received all necessary prior approvals

TABLE OF CONTENTS

or waivers from the applicable bank regulatory authorities and any applicable waiting periods have expired. Neither Byline nor Inland is aware of any material governmental approvals or actions that are required for completion of the merger or bank merger other than those described below, all of which have been obtained. It is presently contemplated that if any such additional governmental approvals or actions are required, those approvals or actions will be sought. However, there can be no assurance that any additional approvals or actions will be obtained.

Federal Reserve. Byline is registered as a bank holding company under the Bank Holding Company Act of 1956, which we refer to as the BHC Act. Inland also is a registered bank holding company under the BHC Act. As a result, the merger is subject to prior approval of the Federal Reserve under the BHC Act, unless a waiver from the prior approval requirement is available pursuant to Regulation Y under the BHC Act. In accordance with Regulation Y, on January 13, 2023, Byline submitted a request to the Federal Reserve Bank of Chicago for a waiver from the requirement under Section 3 of the BHC Act for prior approval of the Federal Reserve. On April 12, 2023, the Federal Reserve granted the requested waiver.

In connection with Byline’s request for a waiver from the requirement to obtain the Federal Reserve’s prior approval of the merger, Byline and Daniel L. Goodwin, Inland’s Chairman and Chief Executive Officer and largest stockholder, have entered into a Letter Agreement pursuant to which Byline has agreed to purchase, prior to the Effective Time, approximately 2,408,992 shares of Inland common stock beneficially owned by Mr. Goodwin at a price per share based on the per share merger consideration to be paid by Byline to Inland stockholders at closing pursuant to the merger agreement. The purpose of the letter agreement is to ensure that Mr. Goodwin does not own more than 10.0% of the outstanding shares of Byline common stock following the effectiveness of the merger. The purchase price to be paid by Byline to Mr. Goodwin will be paid in cash, and we expect that the transaction will be completed on the business day immediately prior to the closing date of the merger. The per share cash purchase price to be paid by Byline for Mr. Goodwin’s shares under the Letter Agreement will be based on the anticipated exchange ratio of 0.19 share of Byline common stock and the anticipated cash consideration of $0.68 per share of Inland common stock. For purposes of calculating the purchase price under the Letter Agreement, Byline and Mr. Goodwin have agreed that the value of a share of Byline common stock will be equal to the Byline closing price, which is defined as the volume weighted average price of one share of Byline common stock as reported on the NYSE for the five (5) business days ending on the business day immediately prior to the closing date. The Byline closing price is the same price at which (i) cash in lieu of fractional shares of Byline common stock that would otherwise be issued in the merger, and (ii) the price used in determining the cash payment that holders of outstanding Inland stock options will be entitled to receive under the merger agreement will be determined. Following completion of the purchase by Byline of Mr. Goodwin’s shares of Inland common stock, Mr. Goodwin is expected to beneficially own approximately 22,513,473.50 shares of Inland common stock, which shares will be converted into the merger consideration upon closing of the merger in accordance with the terms of the merger agreement. Following completion of the merger, it is anticipated that Mr. Goodwin will beneficially own approximately 9.8% of the outstanding shares of Byline common stock.

FDIC. The merger of Inland Bank with and into Byline Bank is subject to the prior approval of the FDIC under the Bank Merger Act of 1960, as amended, which we refer to as the Bank Merger Act. On January 13, 2023, Byline Bank and Inland Bank filed their Bank Merger Act Application for approval of the bank merger with the FDIC. On February 24, 2023, the FDIC approved the bank merger. In reviewing that application, the FDIC was required to consider the following:

•

competitive factors, such as whether the bank merger will result in a monopoly or whether the benefits of the bank merger to the public in meeting the needs and convenience of the community clearly outweigh the bank merger’s anticompetitive effects or restraints on trade; and

•

banking and community factors, which include an evaluation of:

•

the financial and managerial resources of Byline Bank, including its subsidiaries, and of Inland Bank, and the effect of the proposed transaction on these resources;

•

management expertise;

•

internal control and risk management systems;

TABLE OF CONTENTS

•

the capital of Inland Bank;

•

the convenience and needs of the communities to be served; and

•

the effectiveness of Inland Bank and Byline Bank in combating money laundering activities.

The application process included publication and opportunity for comment by the public. The FDIC was required to consider any properly filed comments and protests from community groups and others regarding (among other issues) each institution’s performance under the Community Reinvestment Act.

Mergers approved by the FDIC under the Bank Merger Act, with certain exceptions, may not be consummated until thirty (30) days after the date of approval, during which time the U.S. Department of Justice may challenge such merger on antitrust grounds and may require the divestiture of certain assets and liabilities. With approval of the FDIC and the Department of Justice, that waiting period may be, and customarily is, reduced to no less than fifteen (15) days. The waiting period was reduced to fifteen (15) days and the U.S. Department of Justice did not challenge the merger or bank merger during such fifteen (15) day period.

IDFPR. The merger of Inland Bank with and into Byline Bank is subject to the prior approval of the IDFPR. On January 13, 2023, Byline Bank submitted to the IDFPR a copy of the Bank Merger Act Application filed with the FDIC and such other information as required by the IDFPR. On March 31, 2023, the IDFPR approved the bank merger.

The approval of a merger application by a regulatory authority only means that the regulatory criteria for approval have been satisfied. The process of obtaining regulatory approval does not include a review of the adequacy of the merger consideration. Further, regulatory approvals do not constitute an endorsement or recommendation of the merger.

Accounting Treatment

For accounting and financial reporting purposes, the merger will be accounted for under the acquisition method of accounting for business combinations in accordance with GAAP. Under the acquisition method of accounting, the assets (including identifiable intangible assets) and liabilities (including executory contracts and other commitments) of Inland as of the effective time will be recorded at their respective fair values and added to those of Byline. Any excess of purchase consideration over the fair values is recorded as goodwill. Consolidated financial statements of Byline issued after the merger will reflect these fair values and will not be restated retroactively to reflect the historical consolidated financial position or results of operations of Inland.

Public Trading Markets

Byline common stock is listed on the NYSE under the symbol “BY”. The Byline common stock issuable in the merger will be listed on the NYSE. There is no established public trading market for shares of Inland common stock and no broker makes a market in the stock.

Exchange of Shares in the Merger

Byline has engaged American Stock Transfer & Trust Company, LLC to act as its exchange agent to handle the exchange of Inland common stock for the merger consideration. Within ten (10) business days after the effective time, the exchange agent will send to each holder of record of Inland common stock a letter of transmittal for use in the exchange with instructions explaining how to surrender Inland common stock certificates and/or book entry shares to the exchange agent. Holders of Inland common stock who cannot locate their stock certificates should follow the instructions set forth in the letter of transmittal for lost or stolen stock certificates. As soon as reasonably practicable after its receipt of properly completed and signed letters of transmittal and accompanying Inland stock certificates, if any, Byline’s exchange agent will issue shares of Byline common stock and cash representing the merger consideration, together with cash in lieu of any fractional shares, in each case subject to any required withholding taxes. No interest will be paid on any cash payment. Until the certificates representing Inland common stock are surrendered for exchange, holders of such certificates will not receive the merger consideration or dividends or distributions on the

TABLE OF CONTENTS

shares of Byline common stock into which such shares of Inland common stock have been converted. When the certificates are surrendered to Byline’s exchange agent, any unpaid dividends or other distribution will be paid without interest, subject to any required withholding taxes. In no event will Byline, the exchange agent, or any other person be liable to any former holder of shares of Inland common stock for any amount delivered in good faith to a public official pursuant to applicable abandoned property, escheat or similar laws.

Holders of Inland common stock should follow the instructions in the letter of transmittal for sending their stock certificates to the exchange agent.

Dissenter’s Rights

If the merger is consummated, Inland stockholders who have complied with the applicable requirements and procedures of Sections 3-202 and 3-203 of the MGCL will be entitled to demand appraisal of their shares of Inland common stock, which we refer to in this section as Inland shares, and receive in lieu of the merger consideration a cash payment equal to the “fair value” of their Inland shares, as determined in accordance with the applicable provisions of the MGCL, plus interest, if any, on the amount determined to be the fair value, subject to the provisions of Sections 3-202 through 3-213 of the MGCL, as further described herein. Such appraised value may be greater than, the same as, or less than, the merger consideration. Any Inland stockholder contemplating the exercise of such appraisal rights should review carefully the provisions of Sections 3-202 through 3-213 of the MGCL, particularly the procedural steps required to properly demand and perfect such rights and is encouraged to consult personal legal counsel.

THE FOLLOWING SUMMARY IS NOT A COMPLETE STATEMENT OF THE LAW PERTAINING TO APPRAISAL RIGHTS UNDER SECTIONS 3-202 THROUGH 3-213 OF THE MGCL AND IS QUALIFIED IN ITS ENTIRETY BY THE FULL TEXT OF SECTIONS 3-202 AND 3-213 OF THE MGCL, A COPY OF WHICH IS ATTACHED TO THIS PROXY STATEMENT/PROSPECTUS AS APPENDIX B AND IS INCORPORATED BY REFERENCE HEREIN. THE FOLLOWING SUMMARY DOES NOT CONSTITUTE ANY LEGAL OR OTHER ADVICE NOR DOES IT CONSTITUTE A RECOMMENDATION THAT INLAND STOCKHOLDERS EXERCISE APPRAISAL RIGHTS UNDER SECTIONS 3-202 AND 3-203 OF THE MGCL.

Under Section 3-203, an Inland stockholder who wished to exercise his, her or its dissenter’s rights must deliver a written notice of such stockholder’s objection to the merger to Inland at or prior to the special meeting. Any such objection should be sent to Inland at 2805 Butterfield Road, Oak Brook, Illinois 60523, Attention: Peter Stickler. A stockholder who wished to exercise his, her or its dissenter’s rights cannot vote the shares of Inland common stock held by such dissenting stockholder in favor of the merger.

If the merger is approved by the requisite percentage of shares of Inland common stock, then dissenting Inland stockholders who have complied with the written objection requirements discussed above will possess the right to receive payment for the shares of Inland common stock held by them.

Promptly after the effective time of the merger, Byline, as the surviving corporation in such merger, must give written notice of the effective time of the merger to each former holder of shares of Inland common stock who has complied with the written objection requirement discussed above. A dissenting stockholder must then deliver a written demand for payment of the fair value of the shares of Inland common stock held by such dissenting stockholder to Byline within 20 days after the effective time of the merger. Any such demand by a dissenting stockholder should be sent to Byline at 180 North LaSalle Street, Suite 300, Chicago, Illinois 60601, Attention: Ana Casanueva, Senior Vice President, Director of Legal.

Byline may, at its option, send a written offer to pay each dissenting stockholder who has made demand for payment what Byline considers to be the fair value of shares held by such dissenting stockholder. Such offer must be accompanied by the following financial information relating to Inland and any other information Byline considers pertinent: (i) a balance sheet as of a date not more than six months prior to the date of the offer and (ii) a profit and loss statement for the 12 months ending on the date of the balance sheet.

TABLE OF CONTENTS

Within 50 days of the effective time of the merger, Byline or any dissenting stockholder who has not yet received payment for the shares of Inland common stock held by such dissenting stockholder may petition a court of equity (in the county in which the principal office of Byline is located, or, the county in which the resident agent of Byline is located) for an appraisal to determine the fair value of the Inland common stock. If more than one such petition is filed, the court will consolidate all of the proceedings into one proceeding.

If the court determines that a dissenting stockholder who has filed such a petition is entitled to an appraisal, then it will appoint three disinterested appraisers to determine the fair value of the Inland common stock on terms and conditions the court considers proper. Within 60 days after their appointment, unless the court establishes a longer time, the appraisers must determine the fair value of the Inland common stock and must file a report with the court stating their conclusion and the reasons therefor. Each party to the appraisal proceedings will also receive a copy of the appraisers’ report. Within 15 days after the report is filed, any party may object to it and request a hearing.

After consideration of the appraisers’ report, the court will either accept, modify or reject the appraisers’ conclusion. If the court rejects the appraisers’ conclusion, it may either remit the proceedings to the same or other appraisers or it may make its own determination of the fair value of the Inland common stock.

Once the fair value of the Inland common stock is determined, Byline must pay each dissenting stockholder participating in the appraisal proceedings the judicially determined value of the shares held by such dissenting stockholder, together with interest, if the court so determines. Byline need not make such payment to a dissenting stockholder unless and until the dissenting stockholder surrenders the certificate representing the shares of Byline common stock to Byline, at the address specified above, or to the transfer agent of Byline. The costs of the appraisal proceedings shall be set by the court and assessed against Byline or, if the court determines that a dissenting stockholder failed to accept an offer for payment by Byline in bad faith, against such dissenting stockholder.

FAILURE TO COMPLY EXACTLY WITH ALL OF THE PROCEDURES SET FORTH IN SECTIONS 3-202 AND 3-203 OF THE MGCL MAY RESULT IN A TERMINATION OR LOSS OF APPRAISAL RIGHTS UNDER SECTIONS 3-202 THROUGH 3-213 OF THE MGCL.

TABLE OF CONTENTS

DESCRIPTION OF THE MERGER AGREEMENT

The following is a summary of selected provisions of the merger agreement. While Byline and Inland believe this description covers the material terms of the merger agreement, it may not contain all of the information that is important to you and is qualified in its entirety by reference to the merger agreement, which is incorporated by reference in its entirety into, and a copy of which is attached as Appendix A to, this proxy statement/prospectus. The parties urge you to read the merger agreement in its entirety.

Explanatory Note

The merger agreement and the summary of its terms in this proxy statement/prospectus have been included only to provide you with information about the terms and conditions of the merger agreement. The representations, warranties and covenants contained in the merger agreement are made by Byline and Inland only for purposes of the merger agreement and as of specific dates and were qualified and subject to certain limitations and exceptions agreed to by Byline and Inland in connection with negotiating 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 made solely for the benefit of the parties to the merger agreement and were negotiated for the purpose of allocating contractual risk between the parties to the merger agreement rather than to establish matters as facts. Stockholders are not third-party beneficiaries under the merger agreement. The representations and warranties may also be subject to a contractual standard of materiality or material adverse effect different from those generally applicable to stockholders and reports and documents filed with the SEC, and, in some cases, they may be qualified by disclosures made by one party to the other, which are not necessarily reflected in the merger agreement or other public disclosures made by Byline or Inland. The representations and warranties contained in the merger agreement do not survive the effective time.

Moreover, information concerning the subject matter of the representations, warranties and covenants, 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, and subsequent developments or new information may not be fully reflected in public disclosures of Byline or Inland.

For the foregoing reasons, the representations, warranties and covenants or any descriptions of those provisions should not be read alone or relied upon as characterizations of the actual state of facts or condition of Byline or Inland or any of their respective subsidiaries or affiliates. Instead, such provisions or descriptions should be read only in conjunction with the other information provided elsewhere in this proxy statement/prospectus or incorporated by reference into this proxy statement/prospectus. Please see the section entitled “Where You Can Find More Information”. Byline will provide additional disclosures in its public reports to the extent it is aware of the existence of any material facts that are required to be disclosed under federal securities laws and that might otherwise contradict the terms and information contained in the merger agreement and will update such disclosure as required by federal securities laws.

The Merger

Upon the terms and subject to the conditions of the merger agreement, merger sub will merge with and into Inland with Inland as the surviving corporation and wholly owned subsidiary of Byline, immediately followed by the merger of Inland with and into Byline, with Byline continuing as the surviving corporation. Immediately following the completion of the parent merger, Inland Bank will merge with and into Byline Bank, with Byline Bank as the resulting bank. The separate existence of Inland will cease, with all its rights, privileges, immunities, power and franchises.

Effects of the Merger

As a result of the merger, the shares of Inland common stock will no longer be outstanding and will automatically be cancelled and retired and cease to exist. Inland stockholders will only participate in Byline’s future earnings and potential growth through their ownership of Byline common stock. All of the other incidents of direct ownership of shares of Inland common stock, such as the right to vote on certain decisions with respect to Inland, to elect directors to the Inland board and to receive dividends and distributions from Inland, will be extinguished upon completion of the merger. All of the property, rights, privileges and

TABLE OF CONTENTS

powers of Byline Bank and Inland Bank will vest in the resulting bank, and all obligations, liabilities, debts, restrictions, disabilities and duties of Byline Bank and Inland Bank will become the obligations, liabilities, debts, restrictions, disabilities and duties of the resulting bank.

Closing and Effective Time of the Merger

The merger agreement provides that the merger will be consummated no later than five (5) business days after the satisfaction or waiver of all the closing conditions, except for those conditions that by their nature are to be satisfied at the closing (but subject to the fulfillment or waiver of those conditions), including the receipt of all regulatory and stockholder approvals and after the expiration of all regulatory waiting periods, unless extended by mutual written agreement of Byline and Inland. The merger will become effective at the time a certificate of merger and articles of merger are executed, acknowledged and filed with, respectively, the Secretary of State of the State of Delaware and the State of Maryland as provided in the DGCL and the MGCL. Subject to the satisfaction or waiver of the closing conditions, the parties are seeking to consummate the merger by the second quarter of 2023. However, it is possible that factors outside the control of Byline and Inland could result in the merger being completed at a later time or not at all. There may be a substantial amount of time between the special meeting and the completion of the merger.

If the merger is not completed by the outside date, the merger agreement may be terminated by either Byline or Inland, provided that this right to terminate is not available to a party whose failure to fulfill its covenants under the merger agreement has been the cause of, or materially contributed to, the failure of the merger to be completed before such date.

For a description of the transaction structure and merger consideration, please see the section entitled “The Merger — Terms of the Merger”.

Byline’s Governing Documents, Directors and Officers Following the Closing

Governing Documents

Byline’s certificate of incorporation and bylaws as they exist immediately before the effective time will be the certificate of incorporation and bylaws of the surviving corporation after the merger and parent merger, in each case until thereafter changed or amended as provided therein or by applicable law.

Directors and Officers

Prior to the effective time to be effective at the effective time, Byline has agreed to appoint one person, mutually agreed upon by both Inland and Byline, as a director to Byline Bancorp’s board and to re-nominate such person as a director for a one-year term at each of Byline’s annual meeting of stockholders to be held in 2023 and 2024. If, during this period, such person for any reason ceases to serve as a director or choses for any reason not to stand for re-election, Byline’s board will promptly appoint another person, as mutually agreed to by Inland and Byline. However, in the event that, at any time during this period, Mr. Goodwin’s beneficial ownership of Byline common stock falls below five percent (5%) of the then outstanding shares of Byline common stock, Byline may, but will not be required to, choose not to re-nominate the person then serving on Byline’s board at the next annual meeting of stockholders

Other than as described above, the directors and officers of Byline immediately prior to the effective time will be the directors and officers of the surviving corporation after the merger and parent merger until the earlier of their resignation or removal or until their respective successors are duly appointed and qualified.

Merger Consideration

Conversion of Inland Common Stock

At the effective time, each share of Inland common stock outstanding immediately prior to the effective time, other than shares, if any, owned by Inland or Byline or as to which statutory appraisal rights have been properly exercised and perfected, will be converted into the right to receive the merger consideration

TABLE OF CONTENTS

consisting of (i) the number of shares of Byline’s common stock, par value $0.01 per share, equal to the quotient obtained by dividing (A) 6,389,351 by (B) the number of shares of Inland common stock issued and outstanding immediately prior to the effective time of the merger (which we refer to as the exchange ratio); and (ii) a cash payment in the amount equal to the quotient obtained by dividing (A) $22,867,150.20 by (B) the number of shares of Inland common stock issued and outstanding immediately prior to the effective time (which we refer to as the cash consideration), subject to adjustment in the event the dollar amount of Inland’s tangible common equity at closing is above or below certain thresholds set forth in the merger agreement; provided, however, that in the event Inland has less than 33,628,162 shares of common stock issued and outstanding at closing, then (1) the exchange ratio will be equal to 0.19 share of Byline common stock and (2) the cash consideration will be equal to $0.68, for each share of Inland common stock issued and outstanding at closing, in each case subject to further adjustment as set forth in the merger agreement and as described below.

Not later than ten (10) days before the expected closing date, Inland will deliver to Byline the Inland estimated closing balance sheet. After Inland’s delivery of the Inland estimated closing balance sheet, Byline and Inland will work together in good faith to agree on the Inland final closing balance sheet. Each of the Inland estimated closing balance sheet and the Inland final closing balance sheet will contain a calculation of Inland’s closing tangible common equity.

Cancellation of Excluded Shares and Dissenting Shares

At the effective time, (i) any shares of Inland common stock beneficially owned by Byline (other than shares held in a trust, fiduciary, or nominee capacity or as a result of debts previously contracted) or held in Inland’s treasury, which we refer to as the excluded shares, and (ii) any dissenting shares (subject to the procedures for dissenting shares described herein) will automatically be cancelled and retired and will cease to exist and no consideration will be issued in exchange therefor.

Dissenting Shares

To the extent dissenters’ rights under Sections 3-202 and 3-203 of the MGCL are applicable to the merger, no dissenting shares will be converted into or represent a right to receive the consideration for such shares set forth in merger agreement. Instead, holders of dissenting shares will be entitled to receive in cash the value of the shares held by such holder to the extent granted under Sections 3-202 and 3-203 of the MGCL. If a holder of dissenting shares thereafter effectively withdraws or loses such dissenters’ rights with respect to such shares then, as of the occurrence of such withdrawal or loss, each such share will be deemed as of the effective time to have been converted into and represent only the right to receive the consideration for such shares set forth in the merger agreement.

For more information regarding dissenters’ rights, please see the section entitled “The Merger — Dissenters’ Rights”.

Rights as Stockholders of Inland

At the effective time, holders of shares of Inland common stock will cease to be, and will have no rights as, stockholders of Inland other than to receive the merger consideration and any dividends or distributions to which they are entitled under the merger agreement.

TABLE OF CONTENTS

Exchange Procedures

As soon as reasonably practicable after its receipt of properly completed and signed letters of transmittal and accompanying Inland stock certificates, if any, Byline’s exchange agent will issue shares of Byline common stock and cash representing the merger consideration, together with cash in lieu of any fractional shares, in each case subject to any required withholding taxes. No interest will be paid on any cash payment. Until the certificates representing Inland common stock are surrendered for exchange, holders of such certificates will not receive the merger consideration or dividends or distributions on the shares of Byline common stock into which such shares of Inland common stock have been converted. When the certificates are surrendered to Byline’s exchange agent, any unpaid dividends or other distribution will be paid without interest, subject to any required withholding taxes. In no event will Byline, the exchange agent, or any other person be liable to any former holder of shares of Inland common stock for any amount delivered in good faith to a public official pursuant to applicable abandoned property, escheat or similar laws.

Holders of Inland common stock should follow the instructions in the letter of transmittal for sending their stock certificates to the exchange agent.

Distributions with Respect to Unexchanged Shares

All shares of Byline common stock to be issued pursuant to the merger will be deemed issued and outstanding as of the effective time and if a dividend or other distribution is declared by Byline in respect of the Byline common stock, the record date for which is at or after the effective time, that declaration will include dividends or other distributions in respect of all shares issuable pursuant to the merger agreement. No dividends or other distributions in respect of Byline common stock will be paid to any holder of any unsurrendered certificate or book-entry shares representing shares of Inland common stock until such certificate (or affidavit of loss in lieu thereof) or book-entry shares are surrendered for exchange in accordance with the merger agreement. Subject to applicable laws, following surrender of any such certificate (or affidavit of loss in lieu thereof) or book-entry shares, there will be issued and/or paid to the holder of a certificate or evidence of shares in book-entry form, as applicable, representing whole shares of Byline common stock issued in exchange therefor, without interest, (i) at the time of such surrender, the dividends or other distributions with a record date after the effective time theretofore payable with respect to such whole shares of Byline common stock and not paid and (ii) at the appropriate payment date, the dividends or other distributions payable with respect to such whole shares of Byline common stock with a record date after the effective time but with a payment date subsequent to surrender, in each case subject to any required withholding taxes.

Fractional Shares of Byline Common Stock

No fractional shares of Byline common stock will be issued to any stockholder of Inland upon completion of the merger. For each fractional share of Byline common stock that would otherwise be issued, Byline will pay cash in an amount equal to the fraction of a share (rounded to the nearest cent) of Byline common stock which the holder would otherwise be entitled to receive multiplied by the Byline closing price, subject to any required withholding taxes. No interest will be paid or accrue on cash payable to holders in lieu of fractional shares.

Consummation of the merger is subject to several federal and state regulatory agency filings and approvals. The merger, parent merger and the bank merger cannot be completed unless and until Byline and Byline Bank, on the one hand, and Inland and Inland Bank, on the other hand, have received all necessary prior approvals or waivers from the applicable bank regulatory authorities and any applicable waiting periods have expired. Neither Byline nor Inland is aware of any material governmental approvals or actions that are required for completion of the merger or bank merger other than those described below, all of which have been obtained. It is presently contemplated that if any such additional governmental approvals or actions are required, those approvals or actions will be sought. However, there can be no assurance that any additional approvals or actions will be obtained.

Federal Reserve. Byline is registered as a bank holding company under the Bank Holding Company Act of 1956, which we refer to as the BHC Act. Inland also is a registered bank holding company under the BHC Act. As a result, the merger is subject to prior approval of the Federal Reserve under the BHC Act, unless an exemption from the prior approval requirement is available pursuant to Regulation Y under the BHC Act. In accordance with Regulation Y, on January 13, 2023, Byline submitted a request to the Federal Reserve Bank of Chicago for a waiver from the requirement under Section 3 of the BHC Act for prior approval of the Federal Reserve. On April 12, 2023, the Federal Reserve granted the requested waiver.

Following completion of the purchase by Byline of Mr. Goodwin’s shares of Inland common stock, Mr. Goodwin is expected to beneficially own approximately 22,513,473.50 shares of Inland common stock, which shares will be converted into the merger consideration upon closing of the merger in accordance with the terms of the merger agreement. Following completion of the merger, it is anticipated that Mr. Goodwin will beneficially own approximately 9.8% of the outstanding shares of Byline common stock.

Stockholder Approval

Inland has agreed to convene a meeting of its stockholders as soon as practicable after the registration statement, of which this proxy statement/prospectus is a part, is declared effective, and will in any event use reasonable best efforts to convene such meeting no later than forty-five (45) calendar days after the registration statement is declared effective, to consider and vote upon the approval of the merger proposal.

TABLE OF CONTENTS

Subject to certain limited exceptions, the Inland board will recommend to Inland stockholders that they approve the merger proposal. Unless the merger agreement is terminated in accordance with its terms, Inland will convene such meeting regardless of whether or not (i) the Inland board has changed its recommendation that Inland stockholders approve the merger proposal or (ii) an acquisition proposal from a third party has been made (discussed in more detail below).

Employee Matters

Byline has agreed to provide, or cause to be provided, to each of the current employees of Inland and its subsidiaries as of immediately prior to the effective time who continue employment with Byline or any of its subsidiaries following the effective time with (i) base compensation that, in the aggregate, is no less favorable than those provided to similarly situated employees of Byline and its subsidiaries, (ii) bonus opportunities that are no less favorable than those provided to similarly situated employees of Byline and its subsidiaries and (iii) employee benefits that are no less favorable than those provided to similarly situated employees of Byline and its subsidiaries.

For a period of one year following the effective time, Byline has agreed to provide, or cause to be provided severance benefits to Inland employees who are employed as of the effective time as set forth in the Inland disclosure schedules.

Byline has agreed to give Inland employees who continue employment with Byline or any of its subsidiaries following the effective time credit for their years of service with Inland for purposes of eligibility to participate, vesting and benefit accruals for vacation and paid time off under any employee benefit plans that such employees may be eligible to participate in after the closing to the same extent recognized by Inland immediately prior to the closing, except to the extent it would result in the duplication of benefits for the same period of service.

Byline has agreed to (i) waive preexisting conditions, waiting periods and actively at work requirements under such plans; and (ii) provide each Inland employee with full credit under medical, dental and health plans for any coinsurance, deductible and maximum out-of-pocket expenses incurred by such employees (and their covered dependents) under comparable plans of Inland or any of its subsidiaries during the portion of the applicable plan year prior to such employee’s participation in any medical, dental or health plans of Byline after the closing.

Indemnification and Directors’ and Officers’ Insurance

Pursuant to the terms of the merger agreement, Inland has agreed to purchase and Byline has agreed to maintain, for six (6) years following the effective time, insurance coverage under the current policy of directors’ and officers’ liability insurance maintained by Inland for actions or omissions occurring at or prior to the effective time; provided, however that if the aggregate premiums for such coverage exceed 250% of the premiums Inland paid for its current directors’ and officers’ insurance policy, Inland will only be required to obtain and Byline will only maintain the most advantageous policies of directors’ and officers’ liability insurance obtainable for a total cost equal to such 250% amount. Following the effective time, to the extent permitted by applicable law, Byline has agreed to indemnify, hold harmless, and advance expenses to the current and former directors, officers and employees of Inland and its subsidiaries for actions taken by them in their position as a director, officer or employee of Inland prior to the effective time.

Acquisition Proposals

Except as described below, Inland has agreed in the merger agreement that it will not and will cause its subsidiaries and affiliates not to: initiate, solicit, knowingly encourage or knowingly facilitate in any way inquiries or proposals with respect to an acquisition proposal, or engage in any negotiations concerning, or provide any confidential nonpublic information to, or have any discussions with, any person relating to an acquisition proposal. Inland also agreed to cease immediately and cause to be immediately terminated any activities, discussions and negotiations with any person (other than Byline) with respect to any acquisition proposal.

Notwithstanding the foregoing limitations, if Inland receives an unsolicited bona fide written acquisition proposal, and the Inland board determines in good faith, after consultation with its outside legal counsel

TABLE OF CONTENTS

and financial advisor, that the acquisition proposal constitutes a superior proposal or is reasonably expected to lead to a superior proposal, and if the Inland board concludes in good faith, after consultation with its outside legal counsel and, with respect to financial matters, its financial advisor, that failing to take such actions would result in a violation of its fiduciary duties, then Inland will: (i) furnish information with respect to it to such person making such acquisition proposal pursuant to a confidentiality agreement with terms no less favorable to it then the terms contained in the confidentiality agreement between Inland and Byline; and (ii) participate in discussions or negotiations regarding such acquisition proposal. Upon receipt of any acquisition proposal, Inland must provide Byline prompt notice thereof and keep Byline apprised of any related developments on a prompt basis.

Under the merger agreement, “superior proposal” means a bona fide written acquisition proposal containing terms that the Inland board determines in good faith to be more favorable to Inland stockholders from a financial point of view than the merger and the transactions contemplated thereby, (i) after receiving the advice of its financial advisors, (ii) after taking into account the likelihood and timing of the consummation of the proposed transaction and (iii) after taking into account all relevant legal, financial, regulatory and other aspects of such proposal.

The merger agreement provides that, unless the merger agreement is contemporaneously terminated in accordance with its terms, the Inland board will not cause or permit Inland to enter into any letter of intent, memorandum of understanding, agreement in principle, acquisition agreement, merger agreement or other agreement (other than a confidentiality agreement referred to above) relating to any acquisition proposal.

If Byline terminates the merger agreement because Inland breaches its covenant not to solicit an acquisition proposal from a third-party or if Inland terminates the merger agreement to enter into an agreement for a superior proposal, Inland will pay to Byline a termination fee equal to approximately $6,840,000. See “— Termination Fee”.

TABLE OF CONTENTS

MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES OF THE INTEGRATED MERGER

The following summary describes the material U.S. federal income tax consequences of the integrated merger to U.S. holders (as defined below) of Inland common stock. The summary is based upon the Code, applicable U.S. Department of the Treasury regulations, judicial decisions and administrative rulings and practice, all as in effect as of the date hereof, and all of which are subject to change, possibly with retroactive effect. This summary does not address any tax consequences of the merger under state, local or foreign laws, or any federal laws other than those pertaining to income tax. In addition, the discussion does not address any alternative minimum tax consequences of the merger.

For purposes of this discussion, the term “U.S. holder” means a beneficial owner that is: an individual citizen or resident of the United States; a corporation (or other entity taxable as a corporation for U.S. federal income tax purposes) created or organized under the laws of the United States or any of its political subdivisions; a trust that (1) is subject to the supervision of a court within the United States and the control of one or more U.S. persons or (2) has a valid election in effect under applicable U.S. Treasury regulations to be treated as a U.S. person; or an estate that is subject to U.S. federal income taxation on its income regardless of its source.

This discussion addresses only those U.S. holders of Inland common stock that hold their Inland common stock as a capital asset within the meaning of Section 1221 of the Code and does not address all the U.S. federal income tax consequences that may be relevant to particular holders of Inland common stock in light of their individual circumstances or to holders of Inland common stock that are subject to special rules, such as a beneficial owner of Inland stock that is not a “U.S. holder”; financial institutions; qualified insurance plans; qualified retirement plans and individual retirement accounts; S corporations or other pass-through entities (or entities or arrangements classified as pass-through entities for U.S. federal income tax purposes), or investors in pass-through entities; persons liable for the alternative minimum tax; insurance companies; tax-exempt organizations; brokers or dealers in securities or currencies; traders in securities that elect to use a mark-to-market method of accounting; persons that hold Inland common stock as part of a straddle, hedge, constructive sale or conversion or other integrated transaction; persons with “applicable financial statements” within the meaning of Section 451(b) of the Code; regulated investment companies; real estate investment trusts; persons whose “functional currency” is not the U.S. dollar; and holders who acquired their shares of Inland common stock through the exercise of an employee stock option, as a restricted stock award or otherwise as compensation or through a tax-qualified retirement plan.

If a partnership (or other entity or arrangement that is treated as a partnership for U.S. federal income tax purposes) holds Inland common stock, the tax treatment of a partner in that partnership generally will depend upon the status of the partner and the activities of the partnership. Partnerships and partners in partnerships should consult their own tax advisors about the tax consequences of the integrated merger to them.

The parties intend for the integrated merger to be treated as a single integrated transaction that qualifies as a “reorganization” within the meaning of Section 368(a) of the Code and for each of Inland and Byline to be considered a party to such reorganization within the meaning of Section 368(b) of the Code. It is a condition to Inland’s obligation to complete the merger that Inland receive an opinion from Barack Ferrazzano Kirschbaum & Nagelberg LLP (or such other law firm acceptable to Inland and Byline), dated the closing date of the merger, and it is a condition to Byline’s obligation to complete the merger that Byline receive an opinion from Vedder Price P.C. (or such other law firm acceptable to Byline and Inland), dated the closing date of the merger, each substantially to the same effect as the opinions described in the preceding. These conditions are waivable, and Byline and Inland undertake to recirculate appropriate soliciting materials and resolicit the votes of Inland stockholders if either of these conditions is waived and the change in U.S. federal income tax consequences is material. These opinions will be based upon representation letters provided by Byline and Inland and upon customary factual assumptions. Neither Byline nor Inland has sought, and neither of them will seek, any ruling from the Internal Revenue Service regarding any matters relating to the integrated merger, and the opinions described above will not be binding on the Internal Revenue Service or any court. Consequently, there can be no assurance that the Internal Revenue Service will not assert, or that a court would not sustain, a position contrary to any of the conclusions set forth above or below. In

TABLE OF CONTENTS

addition, if any of the representations or assumptions upon which the opinions are based are inconsistent with the actual facts, the U.S. federal income tax consequences of the integrated merger could be adversely affected.

The actual tax consequences of the merger to you may be complex and will depend upon your specific situation and upon factors that are not within the control of Byline or Inland. You should consult with your own tax advisor as to the tax consequences of the integrated merger in light of your particular circumstances, including without limitation the applicability and effect of the federal alternative minimum tax and any state, local or foreign and other tax laws and of any changes in those laws.

Federal Income Tax Consequences of the Integrated Merger

Based upon the terms of the merger agreement and the facts and representations contained in the representation letters received from Inland and Byline in connection with the filing of the registration statement on Form S-4 of which this proxy statement/prospectus forms a part, it is the opinion of Barack Ferrazzano Kirschbaum & Nagelberg LLP and Vedder Price P.C. that the integrated merger will be, treated as a single integrated transaction that qualifies as a reorganization within the meaning of Section 368(a) of the Code. Accordingly, no gain or loss will be recognized by Byline or Inland as a result of the integrated merger and the material U.S. federal income tax consequences of the integrated merger to U.S. holders will be as follows:

•

Gain (but not loss) will be recognized by U.S. holders of Inland common stock who receive shares of Byline common stock and cash in exchange for shares of Inland common stock pursuant to the integrated merger, in an amount equal to the lesser of (i) the excess, if any, of the amount of cash plus the fair market value of any Byline common stock received in the integrated merger, over such U.S. holder’s adjusted tax basis in the shares of Inland common stock surrendered by such U.S. holder in the integrated merger and (ii) the amount of cash received by such U.S. holder in the integrated merger (in each case, excluding any cash received in lieu of fractional shares of Byline common stock, which is discussed below under “— Cash in Lieu of Fractional Shares of Byline Common Stock”).

•

Generally, a U.S. holder’s aggregate tax basis in the Byline common stock received by such U.S. holder in the integrated merger in exchange for its Inland common stock, including any fractional shares deemed received by the U.S. holder under the treatment discussed below in “— Cash in Lieu of Fractional Shares of Byline Common Stock,” will equal such U.S. holder’s aggregate tax basis in the Inland common stock surrendered in the integrated merger, increased by the amount of taxable gain (whether such gain is classified as capital gain or dividend income, as discussed below), if any, recognized by such U.S. holder in the integrated merger (other than with respect to cash received in lieu of fractional shares of Byline common stock), and decreased by the amount of cash, if any, received by such U.S. holder in the integrated merger (other than cash received in lieu of fractional shares of Byline common stock).

•

The holding period for the shares of Byline common stock received in the integrated merger, including any fractional shares deemed received by the U.S. holder under the treatment discussed below in “— Cash in Lieu of Fractional Shares of Byline Common Stock,” generally will include the holding period for the shares of Inland common stock exchanged therefor.

In the case of any U.S. holder who acquired different blocks of Inland common stock at different times or at different prices, any gain will be determined separately for each identifiable block of shares exchanged in the integrated merger. U.S. holder should consult its tax advisor prior to the exchange regarding the manner in which cash and Byline common stock received in the exchange should be allocated among different blocks of Inland common stock and with regard to identifying the basis or holding periods of the particular shares of Byline common stock received in the integrated merger.

Any capital gain generally will be long-term capital gain if the U.S. holder held the shares of Inland common stock for more than one year at the effective time of the integrated merger. For U.S. holders of shares of Inland common stock that are non-corporate holders, long-term capital gain generally will be taxed at a U.S. federal income tax rate that is lower than the rate for ordinary income or for short-term capital gain.

TABLE OF CONTENTS

In some cases, including without limitation, if a holder actually or constructively owns Byline common stock other than Byline common stock received pursuant to the integrated merger, gain recognized pursuant to the integrated merger could be treated as having the effect of a 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. Because the possibility of dividend treatment depends upon each holder’s particular circumstances, including the application of constructive ownership rules, holders of Inland common stock should consult their own tax advisors regarding the application of the foregoing rules to their particular circumstances.

Cash in Lieu of Fractional Shares of Byline Common Stock

A U.S. holder who receives cash instead of a fractional share of Byline common stock will be treated as having received the fractional share of Byline common stock pursuant to the integrated merger and then as having exchanged the fractional share of Byline common stock for cash in a redemption by Byline. As a result, such U.S. holder will recognize gain or loss equal to the difference between (i) the amount of cash received by such U.S. holder and (ii) the tax basis allocated to such fractional share of Byline common stock (as described above). Such gain or loss generally will constitute capital gain or loss and will be long-term capital gain or loss if the U.S. holder’s holding period for the Inland common stock exchanged by such U.S. holder is greater than one year as of the effective time. For U.S. holders of shares of Inland common stock that are non-corporate holders, long-term capital gain generally will be taxed at a U.S. federal income tax rate that is lower than the rate for ordinary income or for short-term capital gain. The deductibility of capital losses is subject to limitations. See the above discussion regarding blocks of stock that were purchased at different times or at different prices.

Medicare Net Investment Income Tax

In addition to regular U.S. federal income tax, a U.S. holder that is an individual or estate, or a trust that does not fall into a special class of trusts that is exempt from such tax, is subject to a 3.8% tax on the lesser of (1) the U.S. holder’s “net investment income” (or “undistributed net investment income” in the case of an estate or trust) for the relevant taxable year and (2) the excess of the U.S. holder’s modified adjusted gross income (or adjusted gross income, in the case of an estate or trust) for the taxable year over a certain threshold (which in the case of individuals is between $125,000 and $250,000, depending on the individual’s circumstances). For this purpose, net investment income generally includes dividend income and net gain recognized with respect to a disposition of shares of Inland common stock pursuant to the integrated merger, unless such dividend income or net gain is derived in the ordinary course of the conduct of a trade or business (other than a trade or business that consists of certain passive or trading activities). If you are a U.S. holder that is an individual, estate or trust, please consult your tax advisors regarding the applicability of this tax with respect to your disposition of shares of Inland common stock pursuant to the integrated merger.

Backup Withholding and Information Reporting

Payments of cash to a U.S. holder of Inland common stock pursuant to the integrated merger are subject to information reporting and may, under certain circumstances, be subject to backup withholding (currently at a rate of 24%) unless the holder provides proof of an applicable exemption satisfactory to Byline and the exchange agent or, in the case of backup withholding, furnishes its taxpayer identification number and otherwise complies with all applicable requirements of the backup withholding rules. Any amounts withheld from payments to a U.S. holder under the backup withholding rules are not additional tax and generally will be allowed as a refund or credit against the U.S. holder’s U.S. federal income tax liability, provided the required information is timely furnished to the Internal Revenue Service.

A U.S. holder of Inland common stock, as a result of having received Byline common stock in the integrated merger, will be required to retain records pertaining to the integrated merger. In addition, each U.S. holder of Inland common stock who is a “significant holder” will be required to file a statement with such holder’s U.S. federal income tax return in accordance with Treasury Regulations Section 1.368-3(b) setting forth certain information, including the parties to the integrated merger, the date of the integrated merger and such holder’s basis in the Inland common stock surrendered. A “significant holder” is a holder

TABLE OF CONTENTS

of Inland common stock who, immediately before the integrated merger, owned at least 1% of the vote or value of the outstanding stock of Inland or securities of Inland with a basis for federal income tax purposes of at least $1 million.

Foreign Account Tax Compliance Act

Under Sections 1471 through 1474 of the Code, commonly referred to as the Foreign Account Tax Compliance Act (“FATCA”), a holder of Inland common stock could be subject to a 30% U.S. withholding tax on gross proceeds from its exchange of stock for cash received pursuant to the integrated merger if it holds its stock through a foreign financial institution that has not entered into an agreement with the U.S. government to report certain information regarding accounts with or interests in the institution held by certain United States persons and by certain non-U.S. entities that are wholly or partially owned by United States persons, or that has been designated as a “nonparticipating foreign financial institution” if it is subject to an intergovernmental agreement between the United States and a foreign country, or if other conditions are met. The adoption of, or implementation of, an intergovernmental agreement between the United States and an applicable foreign country, or future U.S. Treasury regulations, may modify these requirements. The Internal Revenue Service has released proposed regulations that, if finalized in their proposed form, would generally eliminate the obligation to withhold on gross proceeds from the sale or other disposition of property that produces U.S. source interest or dividends. Although these proposed Treasury Regulations are not final, taxpayers generally may rely on them until final Treasury Regulations are issued. Holders of Inland common stock should consult their own tax advisors on how these rules may apply to cash payments made in exchange for their stock pursuant to the integrated merger in light of their own individual circumstances.

The discussion is intended only as a summary of material U.S. federal income tax consequences of the integrated merger. This discussion does not address tax consequences that may vary with, or are contingent upon, individual circumstances. Moreover, it does not address any non-income tax or any foreign, state or local tax consequences of the integrated merger. Tax matters are very complicated, and the tax consequences of the integrated merger to you will depend upon the facts of your particular situation. Accordingly, we strongly urge you to consult with a tax advisor to determine the particular federal, state, local and foreign tax consequences, including without limitation tax return reporting, the applicability and effect of the Medicare net investment income tax, the alternative minimum tax and any state, local or foreign and other tax laws and of changes in those laws.

COMPARISON OF STOCKHOLDERS’ RIGHTS

General

Inland is incorporated under the laws of the State of Maryland, and the rights of Inland stockholders are governed by Maryland law, Inland’s articles of incorporation and Inland’s bylaws. As a result of the merger, Inland stockholders will receive shares of Byline common stock and will become Byline stockholders. Byline is incorporated under the laws of the State of Delaware, and the rights of Byline stockholders are governed by the laws of the State of Delaware, Byline’s certificate of incorporation and Byline’s bylaws. Thus, following the merger, the rights of Inland stockholders who become Byline stockholders in the merger will no longer be governed by Inland’s articles of incorporation and bylaws and instead will be governed by the laws of the State of Delaware and Byline’s certificate of incorporation and Byline’s bylaws.

Comparison of Stockholders’ Rights

Set forth below is a summary comparison of material differences between the rights of Inland stockholders under Maryland law and Inland’s articles of incorporation and bylaws (left column) and the rights of Byline stockholders under Delaware law and Byline’s certificate of incorporation and bylaws (right column). While the parties believe that the summary table includes the material differences between the rights of Inland stockholders and those of Byline stockholders, this summary does not include a complete description of all the differences between the rights of the stockholders.

Copies of the full text of Byline’s certificate of incorporation and bylaws currently in effect are available, without charge, by following the instructions in the section entitled “Where You Can Find More Information”.

TABLE OF CONTENTS

DESCRIPTION OF BYLINE’S CAPITAL STOCK

The following description of Byline’s capital stock is a summary of the material terms of Byline’s certificate of incorporation and bylaws.

General

Byline’s authorized capital stock consists of 150,000,000 shares of common stock, $0.01 par value per share, and 25,000,000 shares of preferred stock, par value $0.01 per share. As of April 24, 2023, the last practicable date before the date of this proxy statement/prospectus, there were 37,709,728 shares of Byline common stock and no shares of Byline preferred stock outstanding. The authorized but unissued shares of Byline’s capital stock will be available for future issuance without stockholder approval, unless otherwise required by applicable law or the rules of any applicable securities exchange. All of Byline’s issued and outstanding shares of capital stock are validly issued, fully paid and non-assessable.

Common Stock

Subject to the rights and preferences granted to holders of Byline’s preferred stock then outstanding, and except with respect to voting rights, conversion rights and certain distributions of Byline’s capital stock, holders of Byline common stock rank equally with respect to distributions and have identical rights, preferences, privileges and restrictions, including the right to attend meetings and receive any information distributed by Byline with respect to such meetings.

Dividends. Holders of Byline common stock are equally entitled to receive ratably such dividends as may be declared from time to time by the Byline board out of legally available funds. In no event will any stock dividends or stock splits or combinations of stock be declared or made on common stock unless the shares of common stock at the time outstanding are treated equally and identically, provided that, in the event of a dividend of common stock, shares of common stock shall only be entitled to receive shares of common stock. The ability of the Byline board to declare and pay dividends on Byline common stock is subject to the laws of the State of Delaware, applicable federal and state banking laws and regulations, and the terms of any senior securities (including preferred stock) Byline may then have outstanding. Byline’s principal source of income is dividends that are declared and paid by Byline Bank on its capital stock. Therefore, Byline’s ability to pay dividends is dependent upon the receipt of dividends from Byline Bank.

Voting rights. Each holder of Byline common stock is entitled to one vote for each share of record held on all matters submitted to a vote of stockholders, except as otherwise required by law and subject to the rights and preferences of the holders of any outstanding shares of Byline preferred stock. Holders of Byline common stock are not entitled to cumulative voting in the election of directors. Directors are elected by a plurality of the votes cast.

Liquidation rights. In the event of Byline’s liquidation, dissolution or winding up, holders of Byline common stock are entitled to share ratably in all of Byline’s assets remaining after payment of liabilities, including, but not limited to, the liquidation preference of any then outstanding preferred stock. Because Byline is a bank holding company, Byline’s rights and the rights of Byline’s creditors and stockholders to receive the assets of any subsidiary upon liquidation or recapitalization may be subject to prior claims of Byline’s subsidiary’s creditors, except to the extent that Byline may be a creditor with recognized claims against Byline’s subsidiary.

Preemptive and other rights. Holders of Byline common stock are not entitled to any preemptive, subscription or redemption rights, and no sinking fund will be applicable to Byline common stock.

Preferred Stock; Depositary Shares

Byline’s certificate of incorporation authorizes the Byline board to issue up to 25,000,000 shares of preferred stock, in one or more series. Unless required by law or any stock exchange, the authorized but unissued shares of preferred stock will be available for issuance without further action by Byline stockholders. The Byline board is authorized to divide the preferred stock into series and, with respect to each series, to fix and determine the designation, terms, preferences, limitations and relative rights thereof, including dividend rights, dividend rates, conversion rights, voting rights, redemption rights and terms, liquidation preferences,

TABLE OF CONTENTS

sinking fund provisions and the number of shares constituting the series. Subject to the rights of the holders of any series of preferred stock, the number of authorized shares of any series of preferred stock may be increased (but not above the total number of shares of preferred stock authorized under Byline’s certificate of incorporation) or decreased (but not below the number of shares thereof then outstanding) by the affirmative vote of the holders of a majority in voting power of the outstanding shares. Without stockholder approval, Byline could issue preferred stock that could impede or discourage an acquisition attempt or other transaction that some, or a majority, of Byline stockholders may believe is in their best interests or in which they may receive a premium for their common stock over the market price of the common stock.

Byline does not have any preferred stock outstanding as of the date of this proxy statement/prospectus.

Authorized but Unissued Capital Stock

The DGCL does not generally require stockholder approval for the issuance of authorized shares. These additional shares may be used for a variety of corporate purposes, including future public offerings, to raise additional capital or to facilitate acquisitions. However, the listing requirements of the NYSE, which would apply so long as the common stock remains listed on the NYSE, require stockholder approval of certain issuances equal to or exceeding 20% of the then outstanding voting power or then outstanding number of shares of common stock.

One of the effects of the existence of unissued and unreserved common stock or preferred stock may be to enable the Byline board to issue shares to persons friendly to current management, which issuance could render more difficult or discourage an attempt to obtain control of Byline by means of a merger, tender offer, proxy contest or otherwise, and thereby protect the continuity of Byline’s management and possibly deprive Byline stockholders of opportunities they may believe are in their best interests or in which they may receive a premium for their common stock over the market price of the common stock.

ANTI-TAKEOVER PROVISIONS IN THE CERTIFICATE OF INCORPORATION AND BYLAWS

Business Combination Statute. Byline has elected to opt out of Section 203 of the DGCL, which prohibits a Delaware corporation from engaging in any business combination with any interested stockholder for a period of three (3) years after the date that such stockholder became an interested stockholder, subject to certain exceptions.

Federal banking law. The ability of a third party to acquire Byline’s stock is also limited under applicable U.S. banking laws, including regulatory approval requirements. The BHC Act requires any “bank holding company” to obtain the approval of the Federal Reserve before acquiring, directly or indirectly, more than 5% of Byline’s outstanding common stock. Any “company” (as defined in the BHC Act) other than a bank holding company is required to obtain the approval of the Federal Reserve before acquiring “control” of Byline. “Control” generally means (i) the ownership or control of 25% or more of a class of voting securities, (ii) the ability to elect a majority of the directors or (iii) the ability otherwise to exercise a controlling influence over management and policies. A person, other than an individual or a qualified family partnership, that controls Byline for purposes of the BHC Act is subject to regulation and supervision as a bank holding company under the BHC Act. In addition, under the Change in Bank Control Act of 1978, as amended, and the Federal Reserve’s regulations thereunder, any person, either individually or acting through or in concert with one or more persons, is required to provide notice to the Federal Reserve prior to acquiring, directly or indirectly, 10% or more of Byline’s outstanding common stock (or any other class of Byline’s voting securities).

Requirements for advance notification of stockholder nominations and proposals. Byline’s bylaws establish advance notice procedures with respect to stockholder proposals and nomination of candidates for election as directors. These procedures provide that notice of such stockholder proposal must be timely given in writing to Byline’s corporate secretary prior to the meeting at which the action is to be taken. Generally, to be timely, notice must be received at Byline’s principal executive offices not less than ninety (90) days nor more than one hundred and twenty (120) days prior to the first anniversary date of the annual meeting for the preceding year. The notice must contain certain information required to be provided by Byline’s bylaws.

TABLE OF CONTENTS

Limits on written consents. Byline’s certificate of incorporation provides that any action to be taken by the stockholders that the stockholders are required or permitted to take must be effected at a duly called annual or special meeting of stockholders. Byline’s stockholders are not permitted to take action by written consent.

Annual meetings; limits on special meetings. Byline held its 2022 annual meeting of stockholders virtually through a live webcast on June 7, 2022. Subject to the rights of the holders of any series of preferred stock, special meetings of the stockholders may be called only by (i) the Byline board, (ii) the Chairperson of the Byline board, (iii) the Chief Executive Officer of Byline, (iv) the President of Byline, or (v) an Executive Vice President of Byline.

Amending Byline’s Certificate of Incorporation and Bylaws

Byline’s certificate of incorporation may be amended or altered in any manner provided by the DGCL. Byline’s bylaws may be adopted, amended, altered or repealed by stockholders only upon the affirmative vote of holders of a majority of the shares of Byline common stock present in person or represented by proxy at the meeting and entitled to vote thereon. Additionally, Byline’s certificate of incorporation provides that Byline’s bylaws may be amended, altered or repealed by the Byline board by a majority vote.

Sole and Exclusive Forum

Byline’s bylaws provide that, unless Byline consents in writing to an alternative forum, the Court of Chancery of the State of Delaware will be the sole and exclusive forum for (i) any derivative action or proceeding brought on Byline’s behalf, (ii) any action asserting a claim of breach of a fiduciary duty owed by any of Byline’s directors, officers, employees or agents to Byline or Byline stockholders, (iii) any action asserting a claim arising pursuant to any provision of the DGCL, Byline’s certificate of incorporation or Byline’s bylaws or (iv) any action asserting a claim that is governed by the internal affairs doctrine. Any person purchasing or otherwise acquiring any interest in any shares of Byline capital stock shall be deemed to have notice of and to have consented to this provision of Byline’s certificate of incorporation. This choice of forum provision may have the effect of discouraging lawsuits against Byline and Byline’s directors, officers, employees and agents. The enforceability of similar choice of forum provisions in other companies’ certificates of incorporation or bylaws has been challenged in legal proceedings, and it is possible that, in connection with one or more actions or proceedings described above, a court could find the provision of Byline’s certificate of incorporation to be inapplicable or unenforceable.

Indemnification and Limitation of Liability

Byline’s bylaws provide generally that Byline will indemnify and hold harmless, to the full extent permitted by law, Byline’s directors, officers, employees and agents, as well as other persons who have served as Byline’s directors, officers, employees or agents and other persons who serve or have served at Byline’s request at another corporation, limited liability company, public limited company, partnership, joint venture, trust, employee benefit plan, fund or other enterprise in connection with any actual or threatened action, suit or proceeding, subject to limited exceptions. Insofar as indemnification for liabilities arising under the Securities Act may be permitted to Byline’s directors, officers and controlling persons, Byline has been informed that, in the opinion of the SEC, such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. Finally, Byline’s ability to provide indemnification to Byline’s directors and officers is limited by federal banking laws and regulations.

Byline’s certificate of incorporation limits, to the full extent permitted by law, the personal liability of Byline’s directors in actions brought on Byline’s behalf or on behalf of Byline stockholders for monetary damages as a result of a director’s breach of fiduciary duty while acting in a capacity as a director. Byline’s certificate of incorporation does not eliminate or limit Byline’s right or the right of Byline stockholders to seek injunctive or other equitable relief not involving monetary damages.

Listing

Byline common stock is listed on the NYSE under the symbol “BY”.

The parties intend that this Agreement be and hereby is adopted as a “plan of reorganization” for purposes of Sections 354 and 361 of the Code.

D. Company Voting Agreements.

ARTICLE 3

EFFECT ON STOCK

3.1 Effect on Stock. At the Effective Time, as a result of the Merger and without any action by any holder of Company Common Stock:

(a) Company Common Stock.

(1) Each share of Company Common Stock issued and outstanding immediately prior to the Effective Time, other than Excluded Common Shares and Dissenting Common Shares,

A-11

TABLE OF CONTENTS

including each share issued pursuant to an award, made prior to the date hereof, in respect of shares of Company Common Stock that is subject to vesting, repurchase or other lapse restriction granted under the Company Stock Plan that is outstanding immediately prior to the Effective Time (a “Company Restricted Stock Award”), will be converted into and constitute the right to receive the following “Per Common Share Consideration”: (i) such number of fully paid and non-assessable shares of Parent Common Stock equal to the quotient obtained by dividing (A) 6,389,351 by (B) the number of shares of Company Common Stock issued and outstanding immediately prior to the Effective Time (the “Exchange Ratio”); provided that in the event that the total number of issued and outstanding shares of Company Common Stock at Closing is less than 33,628,162, then the Exchange Ratio shall be equal to 0.19; and (ii) a cash payment in the amount equal to the quotient obtained by dividing (A) $22,867,150.20 by (B) the number of shares of Company Common Stock issued and outstanding immediately prior to the Effective Time (the “Cash Consideration”) subject to any adjustment pursuant to Section 3.9; provided that in the event that the total number of issued and outstanding shares of Company Common Stock at Closing is less than 33,628,162, then the Cash Consideration shall be equal to $0.68.

(2) All shares of Company Common Stock outstanding immediately prior to the Effective Time will no longer be outstanding and will automatically be canceled and will cease to exist, and no consideration shall be payable for any Excluded Common Shares. Holders of shares of Company Common Stock will cease to be, and will have no rights as, stockholders of the Company, and certificates that represented shares of Company Common Stock before the Effective Time will be deemed for all purposes to represent only the right to receive, without interest, (A) any then unpaid dividend or other distribution with respect to such Company Common Stock having a record date before the Effective Time and (B) the consideration payable in respect of such Company Common Stock pursuant to this Article 3. After the Effective Time, there will be no transfers of shares of Company Common Stock on the stock transfer books of the Company or the Surviving Corporation, and shares of Company Common Stock presented to the Surviving Corporation will be canceled and exchanged in accordance with this Article 3.

(b) Merger Sub Stock. Each share of Merger Sub Stock outstanding immediately prior to the Effective Time will be converted into and become one validly issued, fully paid and nonassessable share of common stock, no par value, of the Surviving Corporation.

3.2 Company Stock Options.

(a) Each option granted by Company to purchase shares of Company Common Stock under the Company Stock Plan that is outstanding as of immediately prior to the Effective Time (a “Company Stock Option”), shall be cancelled in exchange for a cash payment equal to the product of (A) the difference between (i) the sum of (x) the product of the Exchange Ratio multiplied by the Parent Closing Price plus (y) the Cash Consideration, less (ii) the exercise price per share of Company Common Stock under such Company Stock Option, multiplied by (B) the number of shares of Company Common Stock covered by such Company Stock Option (each an “Option Payment”), and the full release of any claims related to such options against the Company and Inland Bank. Prior to the Effective Time, the Company shall enter into an option termination agreement, the form of which shall be reasonably acceptable to Parent, with each holder of such Company Stock Options (each, an “Option Termination Agreement”), and shall take all other actions as necessary to give effect to such transactions, including without limitation, the adoption of any necessary amendments to the applicable plans and award agreements. The Option Payments shall be treated as compensation and shall be payable by the Surviving Corporation net of any applicable withholding Taxes as provided in Section 3.3(e).

(b) At or prior to the Effective Time, the Company, the Company Board and the compensation committee of the Company Board, as applicable, shall (1) adopt any resolutions and take any actions that are reasonably necessary to effectuate the treatment of the Company Stock Options pursuant to Section 3.2(a), and (2) cause the Company Stock Plan to terminate at or prior to the Effective Time. The Company shall not issue any additional options or awards under the Company Stock Plan on or after the date hereof, and the Company shall take all actions necessary to ensure that from and after the

A-12

TABLE OF CONTENTS

Effective Time neither Parent nor the Surviving Corporation will be required to deliver shares of Company Common Stock or other stock of the Company to any person pursuant to or in settlement of Company Stock Options.

(c) As soon as reasonably practicable following the Effective Time and receipt of an executed Option Termination Agreement, the Surviving Corporation shall pay or cause to be paid the Option Payments contemplated by Section 3.2(a).

3.3 Exchange Agent.

(a) At or before the Effective Time, Parent will deposit with its transfer agent or with a depository or trust institution of recognized standing selected by it and reasonably satisfactory to the Company (in such capacity, the “Exchange Agent”), for the benefit of the holders of certificates formerly representing shares of Company Common Stock (collectively, the “Old Certificates”), (1) evidence of shares in book entry form (such book entry shares, “New Certificates”), representing the shares of Parent Common Stock issuable to holders of Old Certificates under this Article 3 and (2) an amount equal to the aggregate cash payable to holders of Company Common Stock pursuant to Sections 3.1 and 3.4 (the “Exchange Fund”).

(b) As promptly as reasonably practicable following the Effective Time, but in no event later than ten (10) business days thereafter, Parent shall cause the Exchange Agent to mail or deliver to each person who was, immediately prior to the Effective Time, a holder of record of Company Common Stock, a form of letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to Old Certificates shall pass, only upon proper delivery of such certificates to the Exchange Agent) containing instructions for use in effecting the surrender of Old Certificates in exchange for the consideration payable pursuant to this Article 3. No interest will accrue or be paid with respect to any New Certificate or cash to be delivered upon surrender of Old Certificates. If any New Certificate is to be issued or cash is to be paid in a name other than that in which the Old Certificate surrendered in exchange therefor is registered, it will be a condition to the exchange that the Old Certificate so surrendered shall be properly endorsed (or accompanied by an appropriate instrument of transfer) and otherwise in proper form of transfer, and that the person requesting the exchange (1) pay any transfer or other similar Taxes required by reason of the issuance of the New Certificate or the making of the cash payment in a name other than the name of the holder of the surrendered Old Certificate or (2) establish to the reasonable satisfaction of Parent (or the Exchange Agent, as the case may be) that any such Taxes have been paid or are not applicable.

(c) No dividends or other distributions with respect to Parent Common Stock having a record date after the Effective Time will be paid to any holder of Company Common Stock until such holder has surrendered the Old Certificate representing such stock as provided herein. Subject to the effect of applicable Law, following surrender of any such Old Certificates, there shall be paid to the holder of New Certificates issued in exchange therefor, without interest, the amount of dividends or other distributions with a record date after the Effective Time previously payable with respect to the shares of Parent Common Stock represented thereby. To the extent permitted by applicable Law, holders of Company Common Stock who receive Parent Common Stock in the Merger shall be entitled to vote after the Effective Time at any meeting of Parent stockholders the number of whole shares of Parent Common Stock into which their respective shares of Company Common Stock are converted, regardless of whether such holders of Company Common Stock have exchanged their Old Certificates for New Certificates in accordance with the provisions of this Agreement.

(d) Parent shall be entitled to rely upon the Company’s stock transfer books and the Company’s register to establish the identity of those persons entitled to receive consideration pursuant to this Article 3, which books and register shall be conclusive with respect thereto. In the event of a dispute with respect to ownership of stock represented by any Old Certificate, Parent shall be entitled to deposit the full consideration represented thereby in escrow with an independent third party providing for the payment to the owner of such consideration upon resolution of such ownership and thereafter be relieved from any and all liability and obligation with respect to any claims thereto. Notwithstanding anything herein to the contrary, no party hereto shall be liable to any former holder of Company Common Stock

A-13

TABLE OF CONTENTS

for any amount properly delivered in good faith to a public official in accordance with applicable abandoned property, escheat or similar Laws.

(e) Parent, the Company, the Surviving Corporation and the Exchange Agent shall be entitled to deduct and withhold from the consideration and other payments otherwise payable pursuant to this Agreement or contemplated hereby such amounts as Parent, the Company, the Surviving Corporation or the Exchange Agent is required to deduct and withhold with respect to the making of such payment under any applicable Law. To the extent that amounts are so withheld, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the person in respect to whom such deduction and withholding was made. If any holder of an Old Certificate requests payment of any cash such person is entitled to pursuant to this Article 3 by means of a wire transfer in his, her or its duly executed and completed letter of transmittal, the Exchange Agent may make payment of such cash such holder is entitled to hereunder by wire transfer in accordance with such request and the cost of any such wire transfer shall be charged to the account of and deducted from the proceeds paid to such holder hereunder.

(f) At any time following the first anniversary of the Effective Time, Parent shall be entitled to require the Exchange Agent to deliver to it any portion of the Exchange Fund which had been made available to the Exchange Agent and not disbursed to holders of Old Certificates (including, without limitation, all interest and other income received by the Exchange Agent in respect of all cash funds made available to it), and thereafter holders of Old Certificates shall be entitled to look solely to Parent (subject to abandoned property, escheat and other similar Laws) with respect to any payment that may be payable upon due surrender of the Old Certificates held by them. Notwithstanding the foregoing, neither Parent nor the Exchange Agent shall be liable to any holder of an Old Certificate for any payment delivered in good faith in respect of such Old Certificate to a public official in accordance with any applicable abandoned property, escheat or other similar Law.

3.4 Fractional Shares. Notwithstanding anything to the contrary in this Agreement, no fractional shares of Parent Common Stock and no certificates or scrip therefor, or other evidence of ownership thereof, will be issued in the Merger, 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 stockholder of Parent. Instead, Parent will pay, as promptly as reasonably practicable following the Effective Time, but in no event later than fifteen (15) business days thereafter, to each holder of Company Common Stock who would otherwise be entitled to a fractional share of Parent Common Stock (after taking into account all Old Certificates delivered by such holder) an amount in cash (without interest and rounded to the nearest cent) determined by multiplying such fraction of a share of Parent Common Stock by the Parent Closing Price.

3.5 Lost, Stolen or Destroyed Certificates. In the event any certificate representing shares of Company Common Stock 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 customary amount 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 shares of Parent Common Stock and any cash, unpaid dividends or other distributions that would be payable or deliverable in respect thereof pursuant to this Agreement had such lost, stolen or destroyed certificate been surrendered.

3.6 Anti-Dilution Adjustments. If Parent changes (or the Parent Board sets a related record date that will occur before the Effective Time for a change in) the number or kind of shares of Parent Common Stock outstanding by way of a stock split, stock dividend, recapitalization, reclassification, reorganization or other transaction, the Per Common Share Consideration will be adjusted appropriately and proportionately to give holders of capital stock of Company the same economic effect as contemplated by this Agreement prior to such event.

3.7 Dissenters’ Rights. Notwithstanding anything to the contrary in this Agreement, to the extent that holders of Company Common Stock are entitled to dissenters’ rights under Section 3-202 of the MGCL, Dissenting Common Shares that are outstanding as of the Effective Time will not be converted into the right to receive the consideration payable in respect of Company Common Stock pursuant to Section 3.1

A-14

TABLE OF CONTENTS

hereof unless and until the holder shall have failed to perfect, or shall have effectively withdrawn or lost, his, her or its right to dissent from the Merger under the MGCL. Such Dissenting Common Shares, as of the Effective Time, will no longer be outstanding and will automatically be canceled and will cease to exist and the holder of any Dissenting Common Share shall be treated in accordance with Section 3-202 of the MGCL and, as applicable, shall be entitled only to such rights as may be granted to such holder pursuant to Section 3-202 of the MGCL with respect thereto. Parent shall be given a reasonable opportunity to review and comment on all notices or other communications to be sent to holders of Dissenting Common Shares, and the Company shall consider in good faith any comments of Parent and revise such notices or communications as may be appropriate. The Company will give Parent (a) prompt notice of any notice or demands for appraisal or payment for shares of Company Common Stock, any withdrawal of demand for payment and any other similar instruments received by the Company and (b) the opportunity to participate in all negotiations and proceedings with respect to any such demands or notices at Parent’s sole cost and expense. The Company will not, without the prior written consent of Parent (such consent not to be unreasonably withheld, conditioned or delayed), settle any such demands or notices or make or offer to make any payment in respect of any such demands or notices. Parent will pay any consideration as may be determined to be due with respect to Dissenting Common Shares pursuant to and subject to the requirements of applicable Law.

3.8 Company Tangible Common Equity Calculation.

(a) Not later than ten (10) days before the expected Closing Date, the Company shall deliver to Parent an estimated and unaudited consolidated balance sheet of the Company, as of the expected Closing Date (the “Company Estimated Closing Balance Sheet”), which shall (1) be prepared in good faith based on all available information at such time pursuant to GAAP and this Agreement, and Schedule 1.1, and (2) include a calculation of Company Tangible Common Equity as of the expected Closing Date.

(b) After delivery of the Company Estimated Closing Balance Sheet, the Parties shall work together in good faith, which in the case of the Company shall include providing Parent with such documentation and information in its possession or control as Parent shall reasonably request, to agree at least one (1) business day prior to the expected Closing Date on an estimated consolidated balance sheet of the Company as of the expected Closing Date (the “Final Closing Balance Sheet”), which shall (1) be prepared in good faith based on all available information at such time, and, unless otherwise agreed upon by Parent and the Company, pursuant to GAAP, this Agreement, and Schedule 1.1 and (2) include a calculation of Company Tangible Common Equity as of the expected Closing Date. The Final Closing Balance Sheet, and the calculation of the Company Tangible Common Equity contained therein, as mutually agreed to by the Parties (such agreement not to be unreasonably withheld, conditioned or delayed), shall become final and binding.

3.9 Adjustments to Cash Consideration.

(a) In the event that the Company Tangible Common Equity as calculated pursuant to Schedule 1.1 and set forth on the Final Closing Balance Sheet is less than $135,350,000.00, then the aggregate Cash Consideration to be paid pursuant to Section 3.1(a) shall be reduced on a dollar-for-dollar basis by the amount by which the Company Tangible Common Equity is less than the $135,350,000.00.

(b) If the Company Tangible Common Equity as calculated pursuant to Schedule 1.1 and set forth on the Final Closing Balance Sheet is greater than $141,350,000.00 then the aggregate Cash Consideration to be paid pursuant to Section 3.1(a) shall be increased on a dollar-for-dollar basis by the amount by which the Company Tangible Common Equity is greater than $141,350,000.00; provided, however, in no event shall the amount of such increase in the aggregate Cash Consideration exceed an amount that would result in either firm referenced in Section 7.2(c) or Section 7.3(c) being unable to deliver the opinion referenced in such sections. In the event that such increase in the aggregate Cash Consideration exceeds an amount that would result in either firm referenced in Section 7.2(c) or Section 7.3(c) being unable to deliver the opinion referenced in such sections, then the aggregate Cash Consideration shall be increased to the maximum amount that would allow such opinions to be delivered,

A-15

and the remaining portion of such increase shall be paid in Parent Common Stock based on the Parent Closing Price.

ARTICLE 6

COVENANTS

6.1 Commercially Reasonable Efforts.

(a) Subject to the terms and conditions of this Agreement and prior to the Effective Time, the Company and Parent will use commercially reasonable efforts to take, or cause to be taken, in good faith, all actions, and to do, or cause to be done, all things necessary, proper, desirable or advisable under applicable Law, so as to permit consummation of the Merger and the Subsequent Mergers as promptly as practicable and otherwise to enable consummation of the transactions contemplated hereby, and each will cooperate with, and furnish information to, the other party to that end.

(b) The Company and Parent will give prompt notice to the other of any fact, event or circumstance known to it that (1) is reasonably likely, individually or taken together with all other facts, events and circumstances known to it, to result in any Material Adverse Effect with respect to it or (2) would cause or constitute a breach of any of its representations, warranties, covenants or agreements contained herein that reasonably could be expected to give rise, individually or in the aggregate, to the failure of a condition in Article 7.

(c) Without limiting Section 6.1(b), from time to time on or prior to the Closing Date, the Company or Parent may, after it becomes aware, supplement any of its representations and warranties with respect to any fact, change, event or circumstance that has had or is reasonably likely to have a Material Adverse Effect on it or which it believes would or would be reasonably likely to cause or constitute a material breach of any of its representations, warranties or covenants contained herein by delivering a supplemental Disclosure Schedule (“Supplemental Disclosure Schedule”). The information contained in any such Supplemental Disclosure Schedule shall not be deemed to have modified any of the representations and warranties of the Company or Parent contained in this Agreement or be considered Previously Disclosed unless it is expressly accepted as such in writing by the other party.

6.2 Stockholder Approvals.

(a) As promptly as practicable following the date upon which the Registration Statement, filed pursuant to Section 6.6, shall have become effective (but in any event within forty-five (45) days thereof), the Company Board will submit to its stockholders the Company Stockholder Matters and any other matters required to be approved or adopted by such stockholders in order to carry out the intentions of this Agreement and the transactions contemplated hereby. In furtherance of that obligation, the Company will take, in accordance with applicable Law and its Constituent Documents, all action necessary, proper, desirable or advisable to convene a meeting of its stockholders (including any adjournment or postponement, the “Company Meeting”) as promptly as practicable (but in any event within forty-five (45) days of the Registration Statement becoming effective, or such other date as mutually agreed to by the parties) to consider and vote upon approval of the Company Stockholder Matters and any such other matters. The Company and the Company Board, as applicable, will each use its reasonable best efforts to obtain from the Company’s stockholders the required vote to approve the Company Stockholder Matters and any such other matters, including soliciting proxies through the Proxy Statement in accordance with applicable Law and recommending that the Company’s stockholders vote in favor of the Company Stockholder Matters (and including such recommendation in the Proxy Statement). The Company shall provide Parent with a reasonable opportunity to review and comment upon all proxy materials prior to the distribution of such proxy materials to stockholders of the Company, and the Company shall consider in good faith any comments of Parent and revise such

A-40

TABLE OF CONTENTS

proxy materials as may be appropriate. Notwithstanding the foregoing, if the Company Board, after consultation with outside advisors including its outside legal counsel and, with respect to financial matters, its financial advisors, determines in good faith that continuing to recommend this Agreement and the Company Stockholder Matters would violate its fiduciary duties under applicable Law, then, in submitting to its stockholders the Company Stockholder Matters, the Company Board may withhold or withdraw or modify in a manner adverse to Parent its recommendation that Company’s stockholders approve this Agreement or submit this Agreement to its stockholders without recommendation (although the resolutions approving this Agreement as of the date hereof may not be rescinded or amended), in which event the Company Board may communicate the basis for its lack of a recommendation to the stockholders in the Proxy Statement or an appropriate amendment or supplement thereto; provided that the Company Board may not take any actions under this sentence until after giving Parent at least five (5) business days (or, if fewer than five (5) business days remain prior to the date of the Company Meeting, such fewer number of days) to respond to such Acquisition Proposal or other event or circumstances giving rise to the determination by the Company Board to take such action (and, in the event such action is taken in response to an Acquisition Proposal, after giving Parent notice of the third party in the Acquisition Proposal and the material terms and conditions of the Acquisition Proposal) and then taking into account any amendment or modification to this Agreement proposed in writing by Parent. Any material amendment to any Acquisition Proposal will be deemed to be a new Acquisition Proposal for purposes of this Section 6.2 and will require a new notice period as referred to in this Section 6.2. Nothing in this Agreement shall be interpreted to excuse (1) the Company or the Company Board from complying with its obligation to submit this Agreement and the other Company Stockholder Matters to its stockholders at the Company Meeting or (2) any party to a Company Voting Agreement from complying with its obligations thereunder. Neither the Company nor the Company Board shall submit any Acquisition Proposal other than the Merger to the vote of its stockholders unless this Agreement shall have first been terminated in accordance with its terms.

(b) The Company shall cooperate with and keep Parent informed on a current basis regarding its solicitation efforts and voting results following the dissemination of the Proxy Statement to the Company’s stockholders.

Each of the Company and Parent will have the right to review in advance, and to the extent practicable, each will consult with the other, in each case subject to applicable Law relating to the exchange of information, with respect to all material written information submitted to any third party or any Governmental Authority in connection with the Requisite Regulatory Approvals and the Required Third Party Consents, other than any information which is otherwise confidential. In exercising the foregoing right, each of the parties will act reasonably and as promptly as practicable. Each party agrees that it will consult with the other party with respect to obtaining all material permits, consents, approvals and authorizations of all third parties and Governmental Authorities necessary or advisable to consummate the transactions contemplated hereby, and each party will keep the other party appraised of the status of material matters relating to completion of the transactions contemplated hereby.

(b) The Company and Parent will, upon request (but subject to applicable confidentiality requirements), furnish the other party with all information concerning itself, its Affiliates, directors,

A-41

TABLE OF CONTENTS

officers and stockholders and such other matters as may be reasonably necessary, proper, desirable or advisable in connection with any filing, notice or application made by or on behalf of such other party or any of its Affiliates with or to any third party or Governmental Authority in connection with the transactions contemplated hereby and to respond to any comment letters received in connection therewith.

(c) Notwithstanding the foregoing or anything else in this Agreement, nothing shall require Parent or the Company to, and the Company and its Subsidiaries shall not, without the prior written consent of Parent, agree to, take any action or commit to take any action in connection with, or agree to any condition on, or request with respect to, any Requisite Regulatory Approval that would (i) materially and adversely affect the business, operations or financial condition of Parent (measured on a scale relative to the Company and its Subsidiaries, taken as a whole), (ii) require Parent or any of its Subsidiaries to make any material and adverse covenants or commitments, or complete any divestitures, whether prior to or subsequent to the Closing, (iii) result in a Material Adverse Effect on the Company and its Subsidiaries, taken as a whole or (iv) or restrict in any material and adverse respect or impose a material burden on Parent or any of its Subsidiaries (including, after the Effective Time, the Company and its Subsidiaries) in connection with the transactions contemplated hereby or with respect to the business or operation of Parent or any of its Subsidiaries (including, after the Effective Time, the Company and its Subsidiaries) (for purposes of clause (iv), materiality shall be measured on a scale relative to the Company and its Subsidiaries, taken as a whole) (a “Burdensome Condition”).

6.4 Authorization and Reservation of Parent Common Stock. The Parent Board shall, as of the date hereof, authorize and reserve the maximum number of shares of Parent Common Stock to be issued pursuant to this Agreement and take, and cause Merger Sub and Byline Bank to take, all other necessary corporate action to consummate the transactions contemplated hereby.

6.5 Exchange Listing. Parent shall file with the NYSE on a timely basis all such notifications and forms necessary for the listing of all shares of Parent Common Stock to be delivered in connection with the Merger, and use its reasonable best efforts to cause all such shares of Parent Common Stock to be issued in the Merger to be approved for listing on the NYSE, subject to official notice of issuance, as promptly as practicable, and in any event before the Effective Time.

6.6 SEC Filings.

(a) Parent will prepare a registration statement on Form S-4 or other applicable form (the “Registration Statement”) to be filed by Parent with the SEC in connection with the issuance of Parent Common Stock in the Merger (including the notice, proxy statement and prospectus and other proxy solicitation materials of the Company constituting a part thereof (the “Proxy Statement”) and all related documents). The parties agree to cooperate, and to cause their Subsidiaries to cooperate, with the other party, its counsel and its accountants, in the preparation of the Registration Statement and the Proxy Statement and to use their reasonable best efforts to cause the filing of the Registration Statement with the SEC within sixty (60) days following the date of this Agreement. Parent will use all reasonable best efforts to cause the Registration Statement to be declared effective under the Securities Act as promptly as reasonably practicable after filing thereof and to maintain the effectiveness (including by filing any necessary amendments or supplements) of such Registration Statement until the Effective Time. Prior to the filing of the Registration Statement, Parent shall consult with the Company with respect to such filing and shall afford the Company and its Representatives reasonable opportunity to review and comment thereon. The Registration Statement and the Proxy Statement shall include all information reasonably requested by the Company to be included. Parent also agrees to take all action (other than qualifying to do business in any jurisdiction in which it is not now so qualified) required to be taken under the Securities Act, the Exchange Act, any applicable state securities Law or “Blue Sky” Laws and rules and regulations thereunder required to carry out the transactions contemplated hereby. The Company agrees to promptly furnish to Parent all information concerning the Company, its Affiliates, officers, directors and stockholders as may be reasonably requested in connection with the foregoing, in a form appropriate (or from which such information can be derived in a commercially reasonable manner) for usage in such document or any such other use.

A-42

TABLE OF CONTENTS

(b) The Company and Parent each agrees, as to itself and its Affiliates, that none of the information supplied or to be supplied by it for inclusion or incorporation by reference in (1) the Registration Statement will, at the time the Registration Statement and each amendment or supplement thereto, if any, becomes effective under the Securities Act, contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading and (2) the Proxy Statement and any amendment or supplement thereto will, at the date of mailing to stockholders and at the time of the Company Meeting, contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which such statement was made, not misleading. The Company and Parent each further agrees that if it becomes aware that any information furnished by it would cause any of the statements in the Proxy Statement or the Registration Statement to be false or misleading with respect to any material fact, or to omit to state any material fact necessary to make the statements therein not false or misleading, to promptly inform the other party thereof and to take appropriate steps to correct the Proxy Statement or the Registration Statement.

(c) Parent shall promptly provide the Company with all comment letters from the SEC or its staff pertaining to the Registration Statement or the Proxy Statement relating to the Company. The Company will, upon request, promptly furnish Parent with all information concerning itself, its Affiliates, directors, officers and stockholders and such other matters as may be reasonably necessary, proper, desirable or advisable in order for Parent to respond promptly to any comments received from the SEC. Parent will advise the Company, promptly after Parent receives notice thereof, of the time when the Registration Statement has become effective or any supplement or amendment has been filed, of the issuance of any stop order or the suspension of the qualification of Parent Common Stock for offering or sale in any jurisdiction, of the initiation or threat of any proceeding for any such purpose, or of any comments or requests by the SEC for the amendment or supplement of the Registration Statement or for additional information. The parties shall use reasonable best efforts to respond (with the assistance of the other party) as promptly as practicable to any comments of the SEC with respect thereto. If prior to the Effective Time any event occurs with respect to the Company, Parent or any Subsidiary of the Company or Parent, respectively, or any change occurs with respect to information supplied by or on behalf of the Company or Parent, respectively, for inclusion in the Proxy Statement or the Registration Statement that, in each case, is required to be described in an amendment of, or a supplement to, the Proxy Statement or the Registration Statement, the Company or Parent, as applicable, shall promptly notify the other of such event (including, prior to entering into any agreement providing for any merger, consolidation, amalgamation, share exchange, business combination, issuance of securities, acquisition of securities, tender offer, exchange offer or other similar transaction involving Parent or any of its Subsidiaries), and the Company or Parent, as applicable, shall cooperate in the prompt filing with the SEC of any necessary amendment or supplement to the Proxy Statement and the Registration Statement and, as required by applicable Law, in disseminating the information contained in such amendment or supplement to the Company’s stockholders and to Parent’s stockholders.

6.7 Press Releases. Each party will consult with the other before issuing any press release, employee communication or other stockholder communication with respect to the Merger or this Agreement and will not issue any such press release or make any such communication without the prior written consent of such other party, which will not be unreasonably withheld or delayed; provided that a party may, without the prior written consent of the other party (but after prior consultation, to the extent practicable in the circumstances), issue such press release or make such communication as are required by applicable Law or securities exchange rules. The Company and Parent will cooperate to develop all public communications of the Company and make appropriate members of management available at presentations related to the transactions contemplated hereby as reasonably requested by the other party.

6.8 Acquisition Proposals. The Company agrees that it will not, and will cause its Subsidiaries and its and its Subsidiaries’ Representatives, agents, advisors and Affiliates not to, solicit or knowingly encourage in any way inquiries or proposals with respect to, or engage in any negotiations concerning, or provide any confidential nonpublic information to, or have any discussions with, any person relating to any Acquisition Proposal; provided that, in the event the Company receives an unsolicited bona fide Acquisition Proposal and the Company Board concludes in good faith, after consultation with its outside legal counsel and financial advisor, that such Acquisition Proposal constitutes or is reasonably expected to lead to a Superior Proposal,

A-43

TABLE OF CONTENTS

the Company may, and may permit its Subsidiaries and its and its Subsidiaries’ Representatives to, furnish or cause to be furnished nonpublic information and participate in such negotiations or discussions if the Company Board concludes in good faith, after consultation with its outside legal counsel, that failure to take such actions would be reasonably likely to result in a violation of its fiduciary duties under applicable Law; provided, further, that, prior to providing any nonpublic information permitted to be provided pursuant to the foregoing proviso, it shall have entered into a confidentiality agreement with such third party on terms no less favorable to it than the confidentiality provisions set forth in the Confidentiality Agreement (without regard to any modification thereof pursuant hereto or lapse of time). The Company will immediately cease and cause to be terminated any activities, discussions or negotiations conducted before the date of this Agreement with any persons other than Parent with respect to any Acquisition Proposal and will use its reasonable best efforts to enforce the confidentiality provisions of any confidentiality or similar agreement relating to an Acquisition Proposal. The Company will promptly advise Parent following receipt of any Acquisition Proposal and the substance thereof (including the identity of the person making such Acquisition Proposal), and will keep Parent apprised of any related developments on a prompt basis.

Neither the Company nor Parent will take any action that would cause the transactions contemplated hereby to be subject to requirements imposed by any Takeover Law and will take or cause to be taken all commercially reasonable steps within its control to exempt (or ensure the continued exemption of) the transactions contemplated hereby from, or if necessary challenge the applicability of, any applicable Takeover Law, as now or hereafter in effect.

6.10 Access; Information.

(a) Each of Parent and the Company agree that upon reasonable notice and subject to applicable Law relating to the exchange of information, such Party will (and will cause its Subsidiaries to) afford the other Party, and its Representatives, such reasonable access during normal business hours throughout the period before the Effective Time to the books, records (including Tax Returns and work papers of independent auditors), properties, personnel and to such other information in its possession or control as the other Party may reasonably request under the circumstances, including for purposes of facilitating the integration of the Company and its Subsidiaries with Parent and its Subsidiaries, and including as may be necessary or advisable to effect the Conversion pursuant to Section 6.14. In addition, the Company will furnish reasonably promptly to Parent (1) to the extent consistent with applicable Law, a copy of each report, schedule and other document filed by it pursuant to the requirements of federal or state banking or securities Laws, and (2) all other information in its possession or control concerning the business, properties and personnel of it and its Subsidiaries as Parent may reasonably request. The Company shall also provide Parent with copies of regular annual, quarterly and monthly financial reports that the Company or Inland Bank prepare in the ordinary course of business, beginning with the first full week after the date hereof until the Effective Time reasonably promptly after they become available. The Company shall also cause to be prepared and provided to Parent the Company’s consolidated audited financial statements (including any related notes and schedules thereto and the signed, unqualified opinion of RSM US LLP, its independent auditor) for the fiscal year ended December 31, 2022 prior to Closing. In addition, the Company shall enter into an engagement letter with Forvis pursuant to which Forvis will prepare audited financial statements (including any related notes and schedules thereto and the signed, unqualified opinion of Forvis) for the Company 401(k) Plan for (i) the fiscal year ended December 31, 2022 and (ii) for the period from January 1, 2023 through the date of liquidation of the Company 401(k) Plan pursuant to Section 6.13(b). The cost of such audited financial statements for the Company 401(k) Plan shall be borne by the Company. The Company and Parent each agree to promptly notify the other of any action, suit, claim, hearing, dispute, subpoena, investigation or proceeding commenced, or to the Knowledge of the Company or Parent, as applicable, threatened against the Company or Parent or any of their respective Subsidiaries that are related to the transactions contemplated by this Agreement. Nothing in this Agreement will require Parent or the Company to afford access or disclose information that would violate applicable Law, jeopardize attorney-client privilege, relate to pending or threatened litigation or investigations, if disclosure might affect the confidential nature of the matters being disclosed or contravene any binding agreement with any third party. The parties will make appropriate substitute arrangements in circumstances where the previous sentence applies. Each of the Company and Parent shall use commercially reasonable

efforts to minimize any interference with the regular business operations of the Company and its Subsidiaries during any such access.

(b) No investigation by the Company or Parent of, or Knowledge that the Company or Parent may have with respect to, the business and affairs of the other Party, pursuant to this Section 6.10 or otherwise, will affect or be deemed to modify or waive any representation, warranty, covenant or agreement of such Party in this Agreement, or the conditions to such Party’s obligation to consummate the transactions contemplated hereby.

(c) The Company shall give reasonable notice to Parent of all meetings of the Company Board and any of its committees, and the board of directors of Inland Bank and any of its committees, and the agenda for or business to be discussed at such meetings. To the extent consistent with applicable Law, the Company shall promptly transmit to Parent copies of all notices, minutes, consents and other materials that the Company or Inland Bank provides to their respective directors; provided that the Company shall not be required to disclose any information or documents related to, and may redact any information or document to the extent it relates to, the transactions contemplated by this Agreement, or any Acquisition Proposal, or any other matter involving attorney-client privileged matters.

(d) The Company shall cause Inland Bank, prior to the Closing Date, (i) to write off all Loans of Inland Bank that are required to be written off by Inland Bank’s regulators or that, in conformity with past practices and policies of Inland Bank and GAAP, should be written off as Loan losses and (ii) to write down potential Loan losses in conformity with past practices and policies of Inland Bank and GAAP. No such write-off or write-down shall result in a breach of any warranty or representation made herein or otherwise have any effect on the determination by the Parties that the conditions to the Merger set forth in Article 7 have been satisfied, fulfilled or waived or have any effect on the calculation of Company Tangible Common Equity. Nothing in this Section 6.10(d) shall require the Company to make any additional provision to Inland Bank’s reserve for loan losses so long as such reserve is adequate and in compliance with GAAP and all regulatory requirements.

(e) Notwithstanding Section 6.10(d), to the extent reasonably requested by Parent, the Company agrees that it shall, and shall cause Inland Bank, to: (a) make any accounting adjustments or entries to its books of account and other financial records; (b) make additional provisions to Inland Bank’s allowance for loan and lease losses; (c) sell or transfer any investment securities held by it; (d) charge off any Loan; (e) create any new reserve account or make additional provisions to any other existing reserve account; (f) make changes in any accounting method; (g) accelerate, defer or accrue any anticipated obligation, expense or income item; and (h) make any other adjustments which would affect the financial reporting of Parent, on a consolidated basis after the Effective Time; provided, however, that neither the Company nor Inland Bank shall be obligated to take any such requested action until immediately prior to the Closing and at such time as the Company shall have received reasonable assurances in writing that all conditions precedent to Parent’s obligations under this Agreement (except for the completion of actions to be taken at the Closing) have been satisfied and, in any case, may be conditioned upon the subsequent occurrence of the Closing, and no such adjustment which the Company or Inland Bank would not have been required to make but for the request by Parent pursuant to the terms of this Section 6.10(e) shall result in a breach of any warranty or representation made herein or otherwise have any effect on the determination by the Parties that the conditions to the Merger set forth in Article 7 have been satisfied, fulfilled or waived or have any impact on the calculation of Company Tangible Common Equity.

(f) Each of Parent and the Company will hold any information it may obtain from the other in connection with this Agreement and the transactions contemplated hereby which is nonpublic and confidential to the extent required by, and in accordance with, the Confidentiality Agreement.

6.11 Supplemental Indentures. At or before the Effective Time, Parent and the Company will execute and deliver, or cause to be executed and delivered, by or on behalf of Parent and the Company, one or more supplemental indentures and other instruments, and take or cause to be taken all such other action, required for the due assumption of the Company’s outstanding debt, Trust Preferred Securities, guarantees, securities, and other agreements as Previously Disclosed.

6.12 Indemnification.

(a) The Parties acknowledge and agree that prior to the Effective Time the Company shall purchase, and Parent shall maintain for the duration of the Tail Coverage Period, a tail policy of directors’ and officers’ liability coverage that provides directors’ and officers’ liability insurance with respect to actions and omissions occurring on or prior to the Effective Time, subject to the following conditions:

(1) On or prior to the Closing Date, the Company shall purchase, at its own expense, for the benefit of the Company and the Surviving Corporation and their respective Subsidiaries (including their respective successors) and persons who were officers or directors of the Company and its Subsidiaries prior to the Closing Date, a prepaid tail policy or policies from the Company’s current directors’ and officers’ liability insurer providing coverages no less favorable to the insured persons than the level and scope of directors’ and officers’ liability as set forth in the Company’s and its Subsidiaries current directors’ and officers’ liability insurance policies in effect as of the Closing (together, such tail policy or policies are referred to as the “Tail Policy”).

(2) The term of the Tail Policy shall be for a period of six (6) years or, if such term of coverage is not available, such other maximum period of coverage available at a cost not exceeding the Maximum Amount (as defined below) (the “Tail Coverage Period”).

(3) In the event such insurer declines to provide the Tail Policy prior to the Closing Date, the Company shall use its commercially reasonable efforts to identify and obtain similar coverage from another insurance carrier of substantially similar size and reputation to that of such former insurer, if such coverage is reasonably obtainable from the marketplace. If after such reasonable efforts another such insurance carrier is unable or unwilling to provide such similar coverage, the Company shall obtain the best coverage available, as determined in the reasonable judgment of the Company, for a cost up to but not exceeding the Maximum Amount (as defined below).

(4) In no event shall the Company expend, in order to provide or maintain the insurance coverages pursuant to this Section 6.12(a), any annual amount, in aggregate, in excess of two hundred fifty percent (250%) of the amount of the aggregate premiums paid by the Company for the current policy term for such purpose (the “Maximum Amount”). If the amount of the premiums necessary to maintain or procure such insurance coverage exceeds the Maximum Amount, the Company shall use reasonable efforts to maintain the most advantageous policies of directors’ and officers’ insurance obtainable for a total cost equal to the Maximum Amount.

(5) Prior to the Effective Time, the Company shall notify the appropriate directors’ and officers’ liability insurers of the Merger and of all pending or, to the Knowledge of the Company, threatened claims, actions, suits, proceedings or investigations asserted or claimed against any officer or director of the Company or Inland Bank, or circumstances to the Knowledge of the Company reasonably likely to give rise thereto to the extent known by the Company or Inland Bank, in accordance with the terms and conditions of the applicable policies. The Company’s and Inland Bank’s directors and officers shall use reasonable efforts to cooperate with the Company (if prior to the Closing Date) or Parent (if after the Effective Time) in obtaining the above-described insurance coverages.

(b) From and after the Effective Time, Parent agrees to indemnify and hold harmless each present and former director or officer of the Company and its Subsidiaries and any other person entitled to indemnification pursuant to the Constituent Documents of the Company and its Subsidiaries (in each case, in such capacities) (individually, a “Company Indemnified Party”, and, collectively, the “Company Indemnified Parties”), and any person who becomes a Company Indemnified Party between the date hereof and the Effective Time, against any costs or expenses (including reasonable attorney’s 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 Inland Bank and pertaining to matters existing or occurring at or prior to the Effective Time, including the transactions contemplated by this Agreement, to the same

A-46

TABLE OF CONTENTS

extent as such persons are indemnified as of the date of this Agreement by the Company or its Subsidiaries pursuant to their respective Constituent Documents in effect on the date of this Agreement; and Parent shall also advance expenses as incurred by such Company Indemnified Party to the same extent as such persons are entitled to advancement of expenses as of the date of this Agreement by the Company or its Subsidiaries pursuant to their respective Constituent Documents in effect on the date of this Agreement; provided, that 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.

(c) Nothing set forth in this Section 6.12 is intended to or shall limit or otherwise affect the representations, warranties, covenants and other agreements of the Company set forth in this Agreement.

(d) The provisions of this Section 6.12 are intended for the benefit of, and will be enforceable, by each of the Company Indemnified Parties, his or her heirs and his or her representatives. In the event that, after the Effective Time, Parent (i) consolidates with or merges into any other person and is not the continuing or surviving corporation or entity or (ii) transfers or conveys all or a substantial portion of its properties and other assets to any person, then, and in each case, Parent shall cause proper provision to be made so that such successors and assigns shall expressly assume the obligations set forth in this Section 6.12.

6.13 Benefits Arrangements.

(a) Compensation and Benefits. Following the Effective Time, Parent shall provide, or shall cause the Surviving Corporation to provide, to each individual who is an employee of the Company and its Subsidiaries immediately prior to the Effective Time (“Covered Employees”), base compensation, bonus opportunities and employee benefits that are consistent with the base compensation, bonus opportunities and employee benefits that Parent offers to its similarly situated employees. From and after the Effective Time, the Surviving Corporation shall, and Parent shall cause the Surviving Corporation to, honor all of the Company Benefit Arrangements, it being understood that the transactions contemplated by this Agreement constitute a “change in control” (or equivalent term) for purposes of such Company Benefit Arrangements; provided that the Surviving Corporation may terminate or discontinue any Company Benefit Arrangements in accordance with the terms of such plan or program and applicable Law.

(b) Termination of Company 401(k) Plan.

(1) If requested in writing by Parent at least ten (10) business days prior to the Effective Time, the Company shall adopt resolutions of the Company Board to terminate the Company’s 401(k) Savings Plan (the “Company 401(k) Plan”) effective immediately prior to, and conditioned upon the occurrence of, the Effective Time and to fully vest all participants in such Company 401(k) Plan. Before adopting such resolutions, the Company shall provide a draft of such resolutions to Parent for an opportunity to comment thereon, which Parent shall not unreasonably delay.

(2) Prior to the termination of the Company 401(k) Plan, the Company or its Subsidiaries shall make contributions to the Company 401(k) Plan with respect to the January 1, 2022 through December 31, 2022 plan year, and, if the Effective Time occurs on or after January 1, 2023, the plan year commencing January 1, 2023 (and if applicable any subsequent plan year commencing prior to the Effective Time) and ending on the date of the Company 401(k) Plan termination in accordance with the terms of the Company 401(k) Plan and applicable Law.

(3) As of the later of the Effective Time and the date on which the Company 401(k) Plan is terminated, Parent shall offer participation in Parent’s tax-qualified defined contribution plan (“Parent 401(k) Plan”) to each person who was eligible to participate in the Company 401(k) Plan as of the date of its termination. Parent shall cause the Parent 401(k) Plan to, following the Closing Date and pursuant to Section 401(a)(31)(D) of the Code, accept rollover contributions of “eligible rollover distributions” (within the meaning of Section 401(a)(31) of the Code) of eligible amounts (including outstanding loans) distributed to employees from the Company 401(k) Plan.

(c) Severance Benefits. Following the Effective Time and for twelve (12) months thereafter, Parent or its Subsidiaries shall cause the Covered Employees who are employed as of the Effective Time to be covered by the severance terms Previously Disclosed, based on such Covered Employee’s compensation and benefits as of immediately prior to the date of termination (or, if greater, based on such Covered Employee’s compensation and benefits with the Company immediately prior to the Effective Time). In connection with the foregoing, such terminated Covered Employees shall receive service credit for years of continuous service with the Company or its Subsidiaries and Parent and its Subsidiaries for purposes of determining the amount of any severance pay under such plan, program or policy. Notwithstanding the foregoing, no Covered Employee eligible to receive severance benefits or a change in control payment under any employment agreement, change in control agreement or similar agreement shall be entitled to participate in the severance plan, program or policy described in this Section 6.13(c).

(d) Service Credit. For purposes of vesting, eligibility to participate and benefit accruals for vacation and paid time off under the Parent Benefit Arrangements, each Covered Employee shall be credited with his or her years of service with the Company and its Subsidiaries and their respective predecessors before the Effective Time, to the same extent as such Covered Employee was entitled, before the Effective Time, to credit for such service under any similar Company Benefit Arrangement in which such Covered Employee participated or was eligible to participate immediately prior to the Effective Time; provided that in no event shall any Covered Employee be eligible to participate in any closed or frozen plan of Parent or Byline Bank. In addition, and without limiting the generality of the foregoing, (i) each Covered Employee shall be immediately eligible to participate, without any waiting time, in any and all Parent Benefit Arrangements to the extent coverage under such Parent Benefit Arrangements is replacing a comparable Company Benefit Arrangement in which such Covered Employee participated immediately before the Effective Time, and (ii) with respect to welfare benefit plans of Parent or Byline Bank in which Covered Employees are eligible to participate, Parent agrees to cause each such welfare benefit plan to waive any preexisting conditions, waiting periods and actively at work requirements under such plans. In no event shall such recognition of service operate to duplicate any benefits of a Covered Employee with respect to the same period of service. For purposes of each Parent Benefit Arrangement providing medical, dental, pharmaceutical and/or vision benefits, Parent shall cause any eligible expenses incurred by Covered Employees and their covered dependents during the portion of the plan year of the comparable Company Benefit Arrangement ending on the date such employee’s participation in the corresponding Parent plan begins to be taken into account under such Parent Benefit Arrangement for purposes of satisfying all deductible, coinsurance and maximum out-of-pocket requirements applicable to such employee and his covered dependents for the applicable plan year of the Parent plan.

(e) No Third Party Rights. This Section 6.13 shall be binding upon and inure solely to the benefit of each party hereto, and nothing in this Agreement, express or implied, is intended to or shall confer upon any other person any right, benefit or remedy of any nature whatsoever under or by reason of this Section 6.13. To the extent permitted by applicable legal requirements, prior to the Effective Time, the Company Board or the appropriate committee thereof, as applicable, shall adopt such amendments to the Company Benefit Arrangements as may be mutually agreed between the Company and Parent; provided, however, that any such amendment shall not be effective until immediately prior to the Effective Time and shall be contingent upon the occurrence of the Effective Time. In no event shall the terms of this Agreement be deemed to (1) alter or limit the ability of Parent or its Subsidiaries to amend, modify, change or terminate any Benefit Arrangement or any other benefit or employment plan, program, agreement or arrangement after the Closing Date, (2) confer upon any current or former employee or other service provider of the Company or its Subsidiaries, any right to employment or continued employment or continued service with Parent or of its Subsidiaries, or constitute or create an employment or agreement with, or modify the at-will status of any, employee or other service provider, (3) permit any payment to be made to an employee or service provider of the Company or its Subsidiaries that requires prior approval or non-objection from a Governmental Authority without obtaining such prior approval or non-objection or (4) alter or limit the ability of Parent or its Subsidiaries to exercise discretion with respect to eligibility, participation, amounts awarded or payable, or benefits provided, under the terms or provisions of any Benefit Arrangement of Parent or its Subsidiaries.

6.14 Conversion, Data Processing and Related Matters. Prior to the Effective Time, the parties agree to cooperate and to employ their commercially reasonable efforts to plan, execute and complete, at Parent’s sole cost, the Conversion in an orderly and efficient manner following the Closing; provided, that in no event shall the Conversion become effective prior to the Effective Time.

Subject to applicable Law, the Company shall, commencing as of the date of this Agreement, provide Parent and Byline Bank with reasonable access to Inland Bank’s offices, systems and facilities and all relevant information and personnel at such times and places as Byline Bank shall reasonably request (with minimal disruption to the Company’s and Inland Bank’s employees, customers and operations) as shall be reasonably necessary to effect the Conversion following the Closing. Nothing contained in this Agreement shall give Parent, directly or indirectly, the right to control or direct the operations of Company or its Subsidiaries prior to the Effective Time, and nothing contained in this Agreement shall give Company, directly or indirectly, the right to control or direct the operations of Parent or its Subsidiaries prior to the Effective Time.

The Company shall use commercially reasonable efforts to cause (x) the delivery to Parent of a Survey and (y) the Title Company to deliver to Parent a Title Commitment and copies of all documents referenced in the Title Commitment exceptions for each real property owned by the Company or any of its Subsidiaries (other than OREO) as soon as reasonably practicable following the date of this Agreement.

(b) For each real property owned by the Company or any of its Subsidiaries, Parent will have a period of ten (10) business days from Parent’s receipt of the last of the Survey, the Title Commitment and all documents referenced in the Title Commitment exceptions with respect to such real property (“Title Review Period”) in which to review such documents and provide the Company with written notice (“Title Notice”) of any condition disclosed in such Survey or Title Commitment that is not reasonably approved by Parent; provided, however, Parent shall be deemed to approve any condition that is a Permitted Lien.

(c) If a Title Notice is timely given by Parent, the Company shall use its commercially reasonable efforts to promptly (but in any event within twenty-five (25) days of the date of the Title Notice) cure or remove, to Parent’s reasonable satisfaction, each condition set forth on the Title Notice.

The subject, scope, manner and method of the Phase II Survey will be subject to the Company’s prior review and reasonable approval, which approval shall not be unreasonably delayed, conditioned or withheld. At all times the Company shall have access to all field data, analytical data and analytical results obtained or generated in connection with the Phase II Survey. Upon Parent’s receipt of a final written report of the Phase II Survey, at the Company’s request, Parent shall promptly deliver to the Company copies of the Phase II Survey report, all written reports, analytical data, correspondence, notices or other written materials relating thereto.

(c) Remediation. If any Phase I Survey or Phase II Survey Report indicates or confirms, in the reasonable discretion of Parent, the presence of an Environmental Condition related to an Owned Real Property Previously Disclosed (an “Owned Environmental Property”) and which requires remediation under an Environmental Law given the current use of such Owned Environmental Property, Parent will have the right to cause such remediation work to be performed on such Owned Environmental Property by an environmental remediation firm mutually agreed to by Parent and the Company, and the Company agrees that it shall bear the Net Remediation Costs (as defined below) of the remediation work performed on such Owned Environmental Property.

(a) The parties intend that the Merger and the Parent Merger, taken together, qualify as a reorganization within the meaning of Section 368(a) and related sections of the Code and that this Agreement constitute a “plan of reorganization” within the meaning of Section 1.368-2(g) of the Treasury Regulations. From and after the date of this Agreement and until the Effective Time, each of the Company and Parent shall use its reasonable best efforts, and shall cause their Subsidiaries to use reasonable best efforts, to cause the Merger and the Parent Merger, taken together, to qualify as a reorganization within the meaning of Section 368(a) of the Code, and will not knowingly take any action, cause any action to be taken, fail to take any action or cause any action to fail to be taken which action or failure to act could prevent the Merger and the Parent Merger, taken together, from qualifying as a reorganization within the meaning of Section 368(a) of the Code. Following the Effective Time, neither the Parent nor any Affiliate of the Parent knowingly shall take any action, cause any action to be taken, fail to take any action, or cause any action to fail to be taken, which action or failure to act could prevent the Merger and the Parent Merger, taken together, from qualifying as a reorganization within the meaning of Section 368(a) of the Code. Within forty-five (45) days following the Effective Time or, if earlier, January 15 of the year following the calendar year in which the Effective Time occurs, the Surviving Corporation shall comply with the reporting requirements of Section 1.6045B-1(a)(2) of the Treasury Regulations. Each of the Company and Parent shall report the Merger and the Parent Merger as an integrated transaction that qualifies as a reorganization within the meaning of Section 368(a) of the Code on its U.S. federal income Tax Return, unless otherwise required pursuant to a “determination” within the meaning of Section 1313(a) of the Code.

A-55

TABLE OF CONTENTS

the party seeking to terminate the Agreement is not then in breach of its representations, warranties or covenants hereunder.

(c) Denial of Stockholder Approval. If the Company Meeting shall have concluded and the Company Stockholder Matters are not approved by the requisite votes of the holders of the Company Common Stock.

(d) Denial or Withdrawal of Application for Regulatory Approval. (1) If the approval of any Governmental Authority required for consummation of the Merger, the Subsequent Mergers or the other transactions contemplated hereby is denied by final, non-appealable action of such Governmental Authority or (2) any application, filing or notice necessary in connection with a Requisite Regulatory Approval has been withdrawn at the request of the applicable Governmental Authority and such Governmental Authority would not accept the re-filing of such application; provided that the right to terminate this Agreement under this Section 8.1(d) shall not be available to any party whose failure to comply with any provision of this Agreement has been the cause of, or materially contributed to, the foregoing.

(e) Outside Date. If the Effective Time has not occurred by the close of business on the Outside Date, provided that the right to terminate this Agreement under this Section 8.1(e) shall not be available to any party whose failure to comply with any provision of this Agreement has been the cause of, or materially contributed to, the failure of the Effective Time to occur on or before such date. As used in this Agreement, the term “Outside Date” (the “Outside Date”) shall mean June 30, 2023, provided that if the sole impediment to Closing is the receipt of the Requisite Regulatory Approvals or any approvals required to consummate the Mortgage Business Disposition, then the Outside Date shall be deemed to be September 30, 2023.

(f) Adverse Action. In the case of Parent only, and prior to the approval of the Company Stockholder Matters by the requisite votes of the holders of the Company Common Stock only, it will have the right to terminate this Agreement if (1) the Company Board (A) submits this Agreement, the Merger and the other transactions contemplated hereby (including the other Company Stockholder Matters) to its stockholders without a recommendation for approval or with material and adverse conditions on such approval, or otherwise withdraws or materially and adversely modifies (or publicly discloses its intention to withdraw or materially and adversely modify) its recommendation referred to in Section 6.2(a), (B) recommends to its stockholders an Acquisition Transaction other than the Merger, (C) breaches its obligations to convene a stockholder meeting to approve this Agreement in accordance with Section 6.2 prior to the Outside Date, or (D) enters into a definitive agreement with respect to an Acquisition Proposal (other than a confidentiality agreement referred to in Section 6.8) or recommends to its stockholders an Acquisition Proposal other than the Merger, or (2) the Company materially breaches Section 6.8.

(a) Except as otherwise provided herein, a termination of this Agreement pursuant to the terms hereof shall be effective immediately upon delivery of written notice by the terminating party to the other parties hereto. If this Agreement is terminated and the Merger and the transactions contemplated hereby are abandoned, no party will have any liability or further obligation under this Agreement, except that this Section 8.2, Section 8.3 and Article 9, as well as any relevant definitions, will survive termination of this Agreement and remain in full force and effect and except that termination will not relieve a party from liability for any willful breach by it of this Agreement.

8.3 Termination Fees.

(a) In the event that, after the date hereof, (1) Parent terminates this Agreement pursuant to Section 8.1(f) or (2) a bona fide Acquisition Proposal shall have been publicly announced or otherwise made known to the Company Board, prior to the event giving rise to termination of this Agreement and, solely with respect to this subclause (2), (A) this Agreement is terminated by either Parent or the Company pursuant to Section 8.1(c), or by Parent pursuant to Section 8.1(b), or, in the event all conditions to the Closing pursuant to Section 7.1 and Section 7.2 other than the conditions set forth in Section 7.1(a) and Section 7.2(c) have been fulfilled or waived or are capable of being fulfilled as of

(b) If the Fee has not been received by Parent within three (3) business days following the first occurrence of a Fee Triggering Event interest shall accrue on the Fee commencing on the forty-fifth (45th) day following the first occurrence of a Fee Triggering Event, at an annual rate equal to the prime rate, as published in the Wall Street Journal on the date that the Fee was first required to be paid to Parent and the Company shall reimburse Parent for all reasonable and documented out-of-pocket expenses incurred by Parent in connection with enforcing the payment of the Fee. The Parties acknowledge that the agreements contained in this Section 8.3 are an integral part of the transactions contemplated hereby, and that, without these agreements, the Parties would not enter into this Agreement.

(c) The payment of the Fee by the Company on the terms set forth herein shall constitute liquidated damages and not a penalty, and shall be the sole remedy of Parent in the event of a termination of this Agreement. In no event shall the Company be required to pay the Fee more than once.

9.4 Waiver; Amendment. Any term, provision or condition of this Agreement may be waived, amended or modified by an instrument in writing signed on behalf of each of the parties hereto at any time by the parties hereto; provided, however, after the approval of the Company Stockholder Matters by the requisite votes of the holders the Company Common Stock, no waiver, amendment or modification of any term, provision or condition hereof shall be made which by Law requires further approval of the stockholders of the Company unless such further approval is obtained. In addition, Parent and the Company may, subject to applicable Law, without approval of their respective boards of directors, make such technical changes to this Agreement, not inconsistent with the purposes hereof, as may be required to effect or facilitate any Requisite Regulatory Approvals or acceptance of the Merger or of this Agreement or to effect or facilitate any filing or recording required for the consummation of any of the transactions contemplated hereby. Each and every right granted to any party hereunder, or under any other document delivered in connection herewith or therewith, and each and every right allowed it by Law or equity, shall be cumulative and may be exercised from time to time. The failure of any party at any time or times to require performance of any provision hereof shall in no manner affect such party’s right at a later time to enforce the same. No waiver by any party of a condition or of the breach of any term, agreement, covenant, representation or warranty contained in this Agreement, whether by conduct or otherwise, in any one or more instances shall be deemed to be or construed as a further or continuing waiver of any such condition or breach or a waiver of any other condition or of the breach of any other term, agreement, covenant, representation or warranty of this Agreement.

9.5 Alternative Structure. Without limiting Section 9.4, before the Effective Time, Parent, subject to prior written notice to the Company Board, may revise the structure of the Merger or otherwise revise the method of effecting the Merger and the transactions contemplated hereby, including without limitation the Parent Merger or Bank Merger, provided that (a) such revision does not alter or change the kind, amount or economic value of consideration to be delivered to stockholders of the Company or otherwise materially and adversely affect the rights of, and benefits received by the Company and its stockholders, (b) such revision does not adversely affect the federal income Tax consequences to the stockholders of the Company as compared to those resulting from the Intended Tax Treatment, (c) such revised structure or method is reasonably capable of consummation without delay in relation to the structure contemplated herein and (d) such revision does not otherwise cause, and could not reasonably be expected to cause, any of the conditions set forth in Article 7 not to be capable of being fulfilled (unless duly waived by the party entitled to the benefits thereof). This Agreement and any related documents will be appropriately amended in accordance with the terms hereof or thereof in order to reflect any such revised structure or method.

9.6 Governing Law. This Agreement shall be governed and construed in accordance with the Laws of the State of Delaware applicable to contracts made and to be performed entirely within that State without regard to conflicts of laws. Each party hereby irrevocably submits to the exclusive jurisdiction of the state and federal courts located in Delaware solely in respect of the interpretation and enforcement of the provisions of this Agreement and of the documents referred to in this Agreement, and in respect of the transactions contemplated hereby, and hereby waives, and agrees not to assert, as a defense in any action, suit or proceeding

A-58

TABLE OF CONTENTS

for the interpretation or enforcement hereof or of any such document, that it is not subject thereto or that such action, suit or proceeding may not be brought or is not maintainable in said court or that the venue thereof may not be appropriate or that this Agreement or any such document may not be enforced in or by such court, and the parties hereto irrevocably agree that all claims with respect to such action or proceeding shall be heard and determined in such court. The parties hereby consent to and grant any such court jurisdiction over the person of such parties and agree that mailing of process or other papers in connection with any such action or proceeding in the manner provided under Section 9.3 or in such other manner as may be permitted by applicable Law shall be valid and sufficient service thereof.

9.7 Waiver of Jury Trial. EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE EACH SUCH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY. EACH PARTY CERTIFIES AND ACKNOWLEDGES THAT (a) NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER, (b) EACH PARTY UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF THIS WAIVER, (c) EACH PARTY MAKES THIS WAIVER VOLUNTARILY AND (d) EACH PARTY HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 9.7.

9.8 Entire Understanding; No Third Party Beneficiaries. This Agreement, the other agreements and documents contemplated hereby and the Confidentiality Agreement represent the entire understanding of the parties hereto regarding the transactions contemplated hereby and supersede any and all other oral or written agreements previously made or purported to be made. Except for Section 6.12, which is intended to benefit the indemnified parties described therein to the extent stated therein, nothing expressed or implied in this Agreement is intended to confer any rights, remedies, obligations or liabilities upon any person other than the Company and Parent. For the avoidance of doubt, notwithstanding anything in the Confidentiality Agreement to the contrary, the parties hereto hereby agree that the execution and delivery of this Agreement does not result in the termination of the Confidentiality Agreement, which remains in full force and effect in accordance with the terms thereof.

9.9 Counterparts. This Agreement may be executed in multiple counterparts, and may be delivered by means of facsimile or email (or any other electronic means such as “.pdf” or “.tiff” files), each of which shall be deemed to constitute an original, but all of which together shall be deemed to constitute one and the same instrument.

9.10 Severability. Each provision of this Agreement shall be interpreted in such manner as to be effective and valid under applicable Law, but in case any one or more provisions contained in this Agreement shall, for any reason, be held to be invalid, illegal or unenforceable in any respect, (a) all other provisions of this Agreement shall nevertheless remain in full force and effect for so long as the economic or legal substance of the transaction contemplated hereby is not affected in a manner materially adverse to any party and (b) the parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in a mutually acceptable manner in order that the transactions contemplated hereby can be consummated as originally contemplated to the greatest extent possible.

9.11 Subsidiary and Affiliate Action. Wherever a party has an obligation under this Agreement to “cause” a Subsidiary or Affiliate of such party or any such Subsidiary’s or Affiliate’s officers, directors, management or employees to take, or refrain from taking, any action, or such action that may be necessary to accomplish the purposes of this Agreement, such obligation of such party shall be deemed to include an undertaking on the part of such party to cause such Subsidiary or Affiliate to take such necessary action. Wherever this Agreement provides that a Subsidiary or Affiliate of a party has an obligation to act or refrain from taking any action, such party shall be deemed to have an obligation under this Agreement to cause such Subsidiary or Affiliate, or any such Subsidiary’s or Affiliate’s officers, directors, management or employees, to take, or refrain from taking, any action, or such action as may be necessary to accomplish the

A-59

TABLE OF CONTENTS

purposes of this Agreement. To the extent necessary or appropriate to give meaning or effect to the provisions of this Agreement or to accomplish the purposes of this Agreement, Parent and the Company, as the case may be, shall be deemed to have an obligation under this Agreement to cause any Subsidiary thereof to take, or refrain from taking, any action, and to cause such Subsidiary’s officers, directors, management or employees, to take, or refrain from taking, any action otherwise contemplated herein. Any failure by an Affiliate of Parent or the Company to act or refrain from taking any action contemplated by this Agreement shall be deemed to be a breach of this Agreement by Parent or the Company, respectively.

9.12 Other Remedies; Specific Performance. Except as otherwise provided herein, any and all remedies herein expressly conferred upon a party will be deemed cumulative with and not exclusive of any other remedy conferred hereby or by Law or equity upon such party, and the exercise by a party of any one remedy will not preclude the exercise of any other remedy. The parties hereto agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that the parties shall be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof in any court of the United States or any state having jurisdiction, this being in addition to any other remedy to which they are entitled at Law or in equity.

9.13 Assignment. No party may assign either this Agreement or any of its rights, interests, or obligations hereunder without the prior written consent of the other parties hereto and any purported assignment in contravention hereof shall be null and void. Subject to the preceding sentence, this Agreement shall be binding upon and shall inure to the benefit of the parties hereto and their respective successors and permitted assigns.

(ii) The value of the stock determined in the proceeding materially exceeds the amount offered by the successor.

(e) The judgment is final and conclusive on all parties and has the same force and effect as other decrees in equity.

In connection with this opinion, we have reviewed and considered, among other things: (i) a draft of the Agreement, dated November 8, 2022; (ii) certain publicly available financial statements and other historical financial information of Company and its banking subsidiary, Inland Bank & Trust, that we deemed relevant; (iii) certain publicly available financial statements and other historical financial information of Parent that we deemed relevant; (iv) certain internal financial projections for Company for the years ending December 31, 2022 through December 31, 2026, as provided by the senior management of Company; (v) publicly available median analyst earnings per share estimates for Parent for the years ending December 31, 2022 through December 31, 2024 with an annual long-term earnings per share and balance sheet growth rate for Parent for the years ending December 31, 2025 and December 31, 2026, as well as publicly available consensus analyst estimated dividends per share for the years ending December 31, 2022 through December 31, 2024 with an annual dividend growth rate for the years ending December 31, 2025 and December 31, 2026, as provided by the senior management of Parent; (vi) the pro forma financial impact of the Merger on Parent based on certain assumptions relating to transaction expenses, purchase accounting adjustments and cost savings, as well as the establishment of certain reserves for current expected credit losses (CECL) accounting standards, as provided by the senior management of Parent; (vii) the publicly reported historical price and trading activity for Parent Common Stock, including a comparison of certain stock trading information for Parent Common Stock and certain stock indices, as well as similar publicly available information for certain other companies, the securities of which are publicly traded; (viii) a comparison of certain financial and market information for Company and Parent with similar financial institutions for which information is publicly available; (ix) the financial terms of certain recent business combinations in the bank and thrift industry (on a nationwide basis), to the extent publicly available; (x) the current market environment generally and the banking environment in particular; and (xi) such other information, financial studies, analyses and investigations and financial, economic and market criteria as we considered relevant. We also discussed with certain members of the senior management of Company and its representatives the business, financial condition, results of operations and prospects of Company and held similar discussions with certain members of the senior management of Parent and its representatives regarding the business, financial condition, results of operations and prospects of Parent.

In performing our review, we have relied upon the accuracy and completeness of all of the financial and other information that was available to us from public sources, that was provided to us by Company, Parent or their respective representatives, or that was otherwise reviewed by us

and we have assumed such accuracy and completeness for purposes of rendering this opinion without any independent verification or investigation. We have further relied on the assurances of the respective senior managements of Company and Parent that they are not aware of any facts or circumstances that would make any of such information inaccurate or misleading in any respect material to our analyses. We have not been asked to undertake, and have not undertaken, an independent verification of any such information and we do not assume any responsibility or liability for the accuracy or completeness thereof. We did not make an independent evaluation or perform an appraisal of the specific assets, the collateral securing assets or the liabilities (contingent or otherwise) of Company or Parent, nor were we furnished with any such evaluations or appraisals. We render no opinion on or evaluation of the collectability of any assets or the future performance of any loans of Company or Parent. We did not make an independent evaluation of the adequacy of the allowance for loan losses of Company or Parent, or the combined entity after the Merger, and we have not reviewed any individual credit files relating to Company or Parent. We have assumed, with your consent, that the respective allowances for loan losses for both Company and Parent are adequate to cover such losses and will be adequate on a pro forma basis for the combined entity.

In preparing its analyses, Piper Sandler used certain internal financial projections for Company for the years ending December 31, 2022 through December 31, 2026, as provided by the senior management of Company. In addition, Piper Sandler used publicly available median analyst earnings per share estimates for Parent for the years ending December 31, 2022 through December 31, 2024 with an annual long-term earnings per share and balance sheet growth rate for Parent for the years ending December 31, 2025 and December 31, 2026, as well as publicly available consensus analyst estimated dividends per share for the years ending December 31, 2022 through December 31, 2024 with an annual dividend growth rate for the years ending December 31, 2025 and December 31, 2026, as provided by the senior management of Parent. Piper Sandler also received and used in its pro forma analyses certain assumptions relating to transaction expenses, purchase accounting adjustments and cost savings, as well as the establishment of certain reserves for CECL accounting standards, as provided by the senior management of Parent. With respect to the foregoing information, the respective senior managements of Company and Parent confirmed to us that such information reflected (or in the case of the publicly available analyst estimates referred to above, were consistent with) the best currently available projections, estimates and judgements of those respective senior managements as to the future financial performance of Company and Parent, respectively, and we assumed that the financial results reflected in such information would be achieved. We express no opinion as to such projections, estimates or judgements, or the assumptions on which they are based. We have also assumed that there has been no material change in Company’s or Parent’s assets, financial condition, results of

operations, business or prospects since the date of the most recent financial statements made available to us. We have assumed in all respects material to our analyses that Company and Parent will remain as going concerns for all periods relevant to our analyses.

For purposes of our analyses, and at your direction and with your consent, we have assumed that the Company Tangible Common Equity as set forth in the Final Closing Balance Sheet (i) will not be less than $134,500,000.00, and therefore that the Cash Consideration will not be reduced, and (ii) will not be greater than $140,500,000.00, and therefore that the Cash Consideration will not be increased. We have also assumed, with your consent, that (i) each of the parties to the Agreement will comply in all material respects with all material terms and conditions of the Agreement and all related agreements required to effect the Merger, that all of the representations and warranties contained in such agreements are true and correct in all material respects, that each of the parties to such agreements will perform in all material respects all of the covenants and other obligations required to be performed by such party under such agreements and that the conditions precedent in such agreements are not and will not be waived, (ii) in the course of obtaining the necessary regulatory or third party approvals, consents and releases with respect to the Merger, no delay, limitation, restriction or condition will be imposed that would have an adverse effect on Company, Parent, the Merger or any related transactions, and (iii) the Merger and any related transactions will be consummated in accordance with the terms of the Agreement without any waiver, modification or amendment of any material term, condition or agreement thereof and in compliance with all applicable laws and other requirements. Finally, with your consent, we have relied upon the advice that Company has received from its legal, accounting and tax advisors as to all legal, accounting and tax matters relating to the Merger and the other transactions contemplated by the Agreement. We express no opinion as to any such matters.

Our opinion is necessarily based on financial, regulatory, economic, market and other conditions as in effect on, and the information made available to us as of, the date hereof. Events occurring after the date hereof could materially affect this opinion. We have not undertaken to update, revise, reaffirm or withdraw this opinion or otherwise comment upon events occurring after the date hereof. We express no opinion as to the trading value of Parent Common Stock at any time or what the value of Parent Common Stock will be once it is actually received by the holders of Company Common Stock.

We have acted as Company’s financial advisor in connection with the Merger and will receive a fee for our services, which fee is contingent upon consummation of the Merger. We will also receive a fee for rendering this opinion, which opinion fee will be credited in full towards the advisory fee which will become payable to Piper Sandler upon consummation of the Merger.

Company has also agreed to indemnify us against certain claims and liabilities arising out of our engagement and to reimburse us for certain of our out-of-pocket expenses incurred in connection with our engagement. Piper Sandler has not provided any other investment banking services to Company in the two years preceding the date hereof. Piper Sandler did not provide any investment banking services to Parent in the two years preceding the date hereof. In the ordinary course of our business as a broker-dealer, we may purchase securities from and sell securities to Company, Parent and their respective affiliates.

Our opinion is directed to the Board of Directors of Company in connection with its consideration of the Agreement and the Merger and does not constitute a recommendation to any shareholder of Company as to how any such shareholder should vote at any meeting of shareholders called to consider and vote upon the approval of the Agreement and the Merger. Our opinion is directed only as to the fairness, from a financial point of view, of the Merger Consideration to the holders of Company Common Stock and does not address the underlying business decision of Company to engage in the Merger, the form or structure of the Merger or any other transactions contemplated in the Agreement, the relative merits of the Merger as compared to any other alternative transactions or business strategies that might exist for Company or the effect of any other transaction in which Company might engage. We also do not express any opinion as to the fairness of the amount or nature of the compensation to be received in the Merger by any Company officer, director or employee, or class of such persons, if any, relative to the amount of compensation to be received by any other shareholder. This opinion has been approved by Piper Sandler’s fairness opinion committee. This opinion may not be reproduced without Piper Sandler’s prior written consent; provided, however, Piper Sandler will provide its consent for the opinion to be included in any regulatory filings, including the Proxy Statement and the Registration Statement, to be filed with the SEC and mailed to shareholders in connection with the Merger.

Based upon and subject to the foregoing, it is our opinion that, as of the date hereof, the Merger Consideration is fair to the holders of Company Common Stock from a financial point of view.

Very truly yours,
