MERGER PROPOSED—YOUR VOTE IS VERY IMPORTANT

Dear Stockholder of PrivateBancorp, Inc.:

On June 29, 2016, PrivateBancorp, Inc. ("PrivateBancorp"), Canadian Imperial Bank of Commerce ("CIBC") and CIBC Holdco Inc. ("Holdco"), entered into an Agreement and Plan of Merger (the "merger agreement"), pursuant to which CIBC has agreed to acquire PrivateBancorp in a stock and cash transaction. Under the terms of the merger agreement, PrivateBancorp will merge with and into Holdco (the "merger"), with Holdco surviving the merger as a wholly owned subsidiary of CIBC. Following the merger, The PrivateBank and Trust Company ("PrivateBank"), PrivateBancorp's banking subsidiary, will be headquartered in Chicago and PrivateBank and Holdco will constitute the primary banking, lending and wealth management platform of CIBC in the U.S. PrivateBancorp is sending this document to ask its common stockholders to vote in favor of the adoption of the merger agreement.

If the merger is completed, you will be entitled to receive for each share of PrivateBancorp common stock owned by you, (i) $18.80 in cash and (ii) 0.3657 common shares of CIBC (which we collectively refer to as the "merger consideration").

The following table shows the implied value of the merger consideration that would be received by PrivateBancorp stockholders in exchange for each share of PrivateBancorp common stock if the per share price of CIBC was $77.11, which was the closing price of CIBC common shares on the New York Stock Exchange, which we refer to as the "NYSE," on June 28, 2016, the last trading day before public announcement of the merger, and if the per share price of CIBC was $75.43, which was the closing share price of CIBC common shares on the NYSE on October 28, 2016, the latest practicable date before the mailing of this proxy statement/prospectus. The exchange ratio of 0.3657 is fixed.

	Price of CIBC common shares on NYSE	Exchange Ratio	Cash Consideration per PVTB share of common stock	Total Consideration per PVTB share of common stock




June 28, 2016	$77.11	0.3657	$18.80	$47.00

October 28, 2016	$75.43	0.3657	$18.80	$46.38

Based on the number of shares of PrivateBancorp common stock outstanding on June 30, 2016, and the number of shares of restricted PrivateBancorp common stock to be replaced in connection with the merger, we expect that the payment of the stock portion of the merger consideration will require CIBC to issue approximately 29 million CIBC common shares in connection with the merger. In addition, based on the number of issued and outstanding CIBC common shares and PrivateBancorp common shares as of June 30, 2016, and based on the exchange ratio of 0.3657, holders of shares of PrivateBancorp common stock as of immediately prior to the closing of the merger will hold, in the aggregate, approximately 7% of the issued and outstanding CIBC common shares immediately following the closing of the merger. Based on the foregoing, the aggregate merger consideration payable to PrivateBancorp stockholders, if the closing occurs, is currently expected to have a value of approximately $3.8 billion.

The market prices of both CIBC common shares and PrivateBancorp common shares will fluctuate before the completion of the merger, and the market price of CIBC common shares may also fluctuate between the completion of the merger and the time you receive any CIBC common shares. Because the exchange ratio is fixed, the value of the merger consideration constituting common shares of CIBC will fluctuate from the date hereof until you receive the CIBC common shares. You should obtain current stock price quotations for CIBC common shares and PrivateBancorp common stock before you vote. CIBC common shares are quoted on the NYSE and the Toronto Stock Exchange ("TSX") under the symbol "CM." PrivateBancorp common stock is quoted on the NASDAQ Stock Market LLC ("NASDAQ") under the symbol "PVTB."

The merger cannot be completed unless PrivateBancorp common stockholders holding at least a majority of the shares outstanding as of the close of business on October 28, 2016, the record date for the special meeting, vote in favor of the adoption of the merger agreement at the special meeting.

The special meeting of PrivateBancorp common stockholders will be held on December 8, 2016, at The PrivateBank Conference Center, 120 South LaSalle Street, Lower Level, Chicago, Illinois, at 8:00 a.m., local time.

YOUR VOTE IS VERY IMPORTANT, REGARDLESS OF THE NUMBER OF SHARES OF PRIVATEBANCORP COMMON STOCK YOU OWN. TO ENSURE YOUR REPRESENTATION AT THE SPECIAL MEETING, PLEASE TAKE TIME TO VOTE BY FOLLOWING THE INSTRUCTIONS CONTAINED IN THIS PROXY STATEMENT/PROSPECTUS AND ON YOUR PROXY CARD. PLEASE VOTE PROMPTLY WHETHER OR NOT YOU EXPECT TO ATTEND THE SPECIAL MEETING. SUBMITTING A PROXY NOW WILL NOT PREVENT YOU FROM BEING ABLE TO VOTE IN PERSON AT THE SPECIAL MEETING.

PRIVATEBANCORP'S BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT PRIVATEBANCORP COMMON STOCKHOLDERS VOTE "FOR" THE PROPOSAL TO ADOPT THE MERGER AGREEMENT AND "FOR" THE OTHER MATTERS TO BE CONSIDERED AT THE SPECIAL MEETING.

The accompanying proxy statement/prospectus describes the special meeting of PrivateBancorp common stockholders, the merger, the documents relating to the merger and other related matters.

Q:

What will I receive as a holder of PrivateBancorp common stock if the merger is completed?

A:

If the merger is completed, each share of PrivateBancorp common stock issued and outstanding immediately prior to the completion of the merger (other than shares held by PrivateBancorp or CIBC (with certain limited exceptions), shares held in treasury by PrivateBancorp and shares in respect of PrivateBancorp restricted stock awards) will be converted into the right to receive 0.3657 common shares of CIBC, which we refer to as the "exchange ratio," and $18.80 in cash, which we refer to collectively as the "merger consideration." Cash will be paid in lieu of fractional shares. See "What happens if I am eligible to receive a fraction of a CIBC common share as part of the per share merger consideration?" below and the section entitled "The Merger—Terms of the Merger—Merger Consideration" beginning on page 37 and the section entitled "Material United States Federal Income Tax Consequences—The Merger—Cash in Lieu of Fractional Shares" beginning on page 90 of this proxy statement/prospectus.

Q:

What will I receive as a holder of PrivateBancorp equity awards if the merger is completed?

A:

If the merger is completed, at the effective time, PrivateBancorp equity awards that are outstanding as of immediately prior to the effective time will be treated as follows. See the section entitled "The Merger Agreement—Treatment of PrivateBancorp Equity Awards" beginning on page 106 of this proxy statement/prospectus.

Each PrivateBancorp option shall be converted automatically into an option to purchase CIBC shares on the terms specified in the merger agreement (including that such CIBC option will have the same vesting terms as the corresponding PrivateBancorp option).

Each award of restricted PrivateBancorp common stock shall be cancelled and replaced with an award of restricted CIBC common shares on the terms specified in the merger agreement (including that such CIBC restricted stock award will have the same vesting terms as the corresponding PrivateBancorp restricted stock award).

Each PrivateBancorp restricted stock unit award shall (i) if unvested, be converted automatically into a cash-settled CIBC restricted stock unit award on the terms specified in the merger agreement (including that such CIBC restricted stock unit award shall have the same vesting terms as the corresponding PrivateBancorp restricted stock unit award), and (ii) if vested, be cancelled and converted automatically into the right to receive a cash payment equivalent in value to the merger consideration, as determined in accordance with the merger agreement, in respect of each share underlying such award plus a cash payment equal to accumulated but unpaid dividend equivalents; provided, that any such vested award that does not provide for settlement upon a change in control shall instead be converted pursuant to clause (i) above.

Each PrivateBancorp performance share unit award shall (i) if unvested, be converted automatically into a CIBC cash-settled restricted stock unit award on the terms specified in the merger agreement (including that such CIBC restricted stock unit award will have the same time-based vesting terms as the corresponding PrivateBancorp performance share unit award and shall not be subject to performance-based vesting conditions), and (ii) if vested, be cancelled and converted automatically into the right to receive a cash payment equivalent in value to the merger consideration, as determined in accordance with the merger agreement, in respect of each share underlying such award plus a cash payment equal to accumulated dividend equivalents; provided, that any such vested award that does not provide for settlement upon a change in control shall instead be converted pursuant to clause (i) above. For purposes of the foregoing, the number of shares of PrivateBancorp common stock underlying each performance share unit award shall be determined by assuming that the applicable performance goals are achieved at the maximum level.

Table of Contents

Each stock unit credited to an account that is deemed invested in PrivateBancorp common stock under PrivateBancorp's deferred compensation plan, shall be converted automatically into a deemed investment in CIBC common shares that will be cash-settled on the terms specified in the merger agreement.

Q:: What is the value of the per share merger consideration?
A:: If the merger is completed, you will be entitled to receive for each share of PrivateBancorp common stock owned by you, (i) $18.80 in cash and (ii) 0.3657 common shares of CIBC, which we collectively refer to as the "merger consideration".

The following table shows the implied value of the merger consideration that would be received by PrivateBancorp stockholders in exchange for each share of PrivateBancorp stock if the per share price of CIBC was $77.11, which was the closing price of CIBC common shares on the New York Stock Exchange, which we refer to as the "NYSE," on June 28, 2016, the last trading day before public announcement of the merger, and if the per share price of CIBC was $75.43, which was the closing price of CIBC common shares on the NYSE on October 28, 2016, the latest practicable date before the mailing of this proxy statement/prospectus. The exchange ratio of 0.3657 is fixed.

October 28, 2016	$	75.43	0.3657	$	18.80	$	46.38

Q:: When is the merger expected to be completed?
A:: We expect the merger will be completed when all of the conditions to completion contained in the merger agreement are satisfied or waived, including the receipt of required regulatory approvals and the approval of the merger agreement proposal at the special meeting. CIBC currently expects the merger will be completed during the first calendar quarter of 2017. However, because fulfillment of some of the conditions to completion of the merger, such as the receipt of required regulatory approvals, are not entirely within our control, we cannot predict the actual timing or provide any assurances as to when or if the merger will occur. See the section entitled "The Merger Agreement—Conditions to the Merger" beginning on page 117.
Q:: What happens if the merger is not completed?
A:: If the merger is not completed, holders of PrivateBancorp common stock will not receive any consideration for their shares in connection with the merger. Instead, PrivateBancorp will remain an independent public company and its common stock will continue to be listed and traded on The NASDAQ Stock Market, referred to as the "NASDAQ."
Q:: When and where is the special meeting being held?
A:: The special meeting will be held at The PrivateBank Conference Center, 120 South LaSalle Street, Lower Level, Chicago, Illinois, on December 8, 2016 at 8:00 a.m. local time.
Q:: Who can vote at the special meeting?
A:: Holders of PrivateBancorp common stock, including holders of PrivateBancorp restricted stock awards, as of the close of business on October 28, 2016, referred to as the "record date," are entitled to vote at the special meeting. Beneficial owners of shares of PrivateBancorp common

Table of Contents

stock as of the record date should receive instructions from their bank, brokerage firm or other nominee describing how to vote their shares.

Q:: What is the quorum requirement for the special meeting?
A:: The presence, in person or represented by proxy, at the special meeting of holders of a majority of the aggregate voting power of the issued and outstanding shares of PrivateBancorp common stock entitled to vote at the special meeting will constitute a quorum. All shares of PrivateBancorp common stock that are present in person or represented by proxy, including abstentions and broker non-votes, will be treated as present for purposes of determining the presence or absence of a quorum for all matters voted on at the special meeting.

Table of Contents

Q:

What does it mean if I get more than one proxy card?

A:

It means you have multiple accounts at the transfer agent and/or with brokers. Please sign and return all proxy cards or vote all your shares online or by telephone to ensure that all your shares are voted.

Q:

If my shares of PrivateBancorp common stock are held in "street name" by my bank, broker or other nominee, will my bank, broker or other nominee vote my shares for me?

A:

Only if you instruct your bank, brokerage firm or other nominee how to vote your shares of PrivateBancorp common stock. If you do not instruct your bank, brokerage firm or other nominee, they will not be able to vote your shares. Please check with your bank, brokerage firm or other nominee and follow the voting procedures they provide.

If your broker, bank or other nominee does not receive voting instructions from you, they will not have the authority to vote your shares. Under such circumstance, a "broker non-vote" would arise. Broker non-votes, if any, will not be considered present at the special meeting for purposes of determining whether a quorum is present at the special meeting, will have the same effect as a vote "AGAINST" the proposal to adopt the merger agreement and, assuming a quorum is present, will have no effect on the advisory (non-binding) proposal on executive compensation payable to the PrivateBancorp's named executive officers in connection with the merger or the adjournment proposal. Thus, for shares of common stock held in "street name," only shares of common stock affirmatively voted "FOR" the proposal to adopt the merger agreement will be counted as a vote in favor of such proposal.

Q:

What happens if I submit my proxy or voting instruction card without indicating how to vote?

A:

If you sign and return your proxy or voting instruction card without indicating how to vote on any particular proposal, your shares of PrivateBancorp common stock represented by your proxy will be voted as recommended by PrivateBancorp's board of directors with respect to that proposal. Unless you check the box on your proxy card to withhold discretionary authority, the proxy holders may use their discretion to vote on other matters relating to the special meeting.

Q:

What happens if I abstain from voting or do not vote at all?

A:

For purposes of the special meeting, an abstention occurs when a stockholder attends the special meeting in person and does not vote or returns a proxy with an "abstain" vote. If you respond with an "abstain" vote on any of the proposals to be considered at the special meeting, your proxy will have the same effect as a vote cast "AGAINST" the merger agreement proposal, the merger-related compensation proposal and the adjournment proposal.

If you fail to vote or fail to instruct your bank, brokerage firm or other nominee how to vote on the proposals to be considered at the special meeting, it will have the same effect as a vote cast "AGAINST" the approval of the merger agreement proposal, and, assuming a quorum is present, will have no effect on the merger-related compensation proposal or the adjournment proposal.

Q:

May I change my vote after I have submitted a proxy?

A:

Yes. If you have not voted through your bank, brokerage firm or other nominee, there are four ways you can change your vote after you have submitted your proxy (whether by mail, telephone or the Internet):

•: by sending a notice of revocation to PrivateBancorp, Inc., Attn: Corporate Secretary, 120 South LaSalle Street, Chicago, Illinois 60603 stating that you would like to revoke your proxy;

viii

Table of Contents

•: by logging onto the Internet website specified on your proxy card in the same manner you would to submit your proxy electronically or by calling the telephone number specified on your proxy card, in each case if you are eligible to do so and following the instructions on the proxy card;
•: by sending a completed proxy card bearing a later date than your original proxy card; or
•: by attending the special meeting and voting in person.

If you choose either of the first two methods, you must take the described action no later than the beginning of the special meeting. If you choose to send a completed proxy card bearing a later date than your original proxy card, the new proxy card must be received before the beginning of the special meeting.

If you have instructed a bank, brokerage firm or other nominee to vote your shares of PrivateBancorp stock, you must follow the directions you receive from your bank, brokerage firm or other nominee in order to change or revoke your vote.

If you are an employee participant that holds your shares of PrivateBancorp stock through the PrivateBancorp, Inc. Savings, Retirement and Employee Stock Ownership Plan ("KSOP"), you must follow the directions you receive from the trustee of such KSOP in order to change or revoke your vote.

Q:: If I want to attend the special meeting, what do I do?
A:: You should come to The PrivateBank Conference Center, 120 South LaSalle Street, Chicago, Illinois, on December 8, 2016 at 8:00 a.m. local time for the meeting. If you hold your shares of PrivateBancorp common stock in "street name," you will need to bring proof of ownership (by means of a recent brokerage statement or letter from your bank, brokerage firm or other nominee) to be admitted to the special meeting. Stockholders of record as of the record date can vote in person at the special meeting. If your shares of PrivateBancorp common stock are held in "street name," then you are not the stockholder of record and you must ask your bank, brokerage firm or other nominee how you can vote at the special meeting.
Q:: What are the material U.S. federal and Canadian income tax consequences of the merger to holders of PrivateBancorp stock?
A:: The merger is intended to qualify as a reorganization for United States federal income tax purposes, and it is a condition to our respective obligations to complete the merger that each of CIBC and PrivateBancorp receive a legal opinion from Mayer Brown LLP and Wachtell, Lipton, Rosen & Katz, respectively, to the effect that (i) the merger will qualify as a "reorganization" within the meaning of Section 368(a) of the Code and (ii) the merger will not result in gain recognition to the holders of PrivateBancorp common stock pursuant to Section 367(a) of the Code (assuming that, in the case of any such holder who would be treated as a "five-percent transferee shareholder" within the meaning of Treasury Regulations Section 1.367(a)-3(c)(5)(ii), such holder enters into a five-year gain recognition agreement in the form provided in Treasury Regulations Section 1.367(a)-8, as provided for in Treasury Regulations Section 1.367(a)-3(c)(1)(iii)(B), and complies with the requirements of that agreement and Treasury Regulations Section 1.367(a)-8 for avoiding the recognition of gain).

Accordingly, a PrivateBancorp common stockholder generally will recognize gain, but not loss, in an amount equal to the lesser of (i) the amount of gain realized (i.e., the excess of the sum of the amount of cash and the fair market value of the CIBC common stock received pursuant to the merger over that holder's adjusted tax basis in its shares of PrivateBancorp common stock surrendered) and (ii) the amount of cash received pursuant to the merger. Further, a PrivateBancorp common stockholder generally will recognize gain or loss with respect to cash

Table of Contents

received instead of fractional shares of CIBC common stock that the PrivateBancorp common stockholder would otherwise be entitled to receive.

It is important to note that the U.S. federal income tax consequences described above may not apply to some holders of PrivateBancorp common stock, as applicable, including certain holders specifically referred to under "The Merger—Material United States Federal Income Tax Consequences" beginning on page 87. Your tax consequences will depend on your individual situation. Accordingly, we strongly urge you to consult your tax advisor for a full understanding of the tax consequences of the merger in your particular circumstances, as well as any tax consequences that may arise from the laws of any other taxing jurisdiction.

Generally, a holder of PrivateBancorp stock who is not, and who is not deemed to be, resident in Canada for purposes of the Canadian Tax Act will not be subject to tax under the Canadian Tax Act in respect of any capital gain realized on the disposition of PrivateBancorp common stock pursuant to the merger. See "The Merger—Certain Canadian Federal Income Tax Consequences" beginning on page 94.

Q:: Do I have appraisal rights in connection with the merger?
A:: Holders of PrivateBancorp common stock are entitled to dissenters' rights of appraisal in connection with the merger under Section 262 of the General Corporation Law of the State of Delaware, which is sometimes referred to as "Delaware law," provided they satisfy the special criteria and conditions set forth in Section 262 of Delaware law. More information regarding these appraisal rights are described in this document, and the provisions of Delaware law that grant appraisal rights and govern such procedures are attached as Appendix D to this document. You should read these provisions carefully and in their entirety. A detailed description of the appraisal rights available to holders of PrivateBancorp common stock and procedures required to exercise statutory appraisal rights is included in the section entitled "The Merger—Dissenters' Rights of Appraisal for Holders of PrivateBancorp Common Stock" beginning on page 99.
Q:: Should I send in my stock certificates now?
A:: No. PrivateBancorp 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 PrivateBancorp stockholders under separate cover and the stock certificates should be sent at that time.
Q:: What will happen to PrivateBancorp and the PrivateBank as a result of the merger?
A:: If the merger is completed, PrivateBancorp will be merged with and into Holdco, a direct wholly-owned subsidiary of CIBC, with Holdco surviving the merger. As a result of the merger, PrivateBancorp will no longer be a publicly held company. Following the merger, PrivateBancorp common stock will be delisted from the NASDAQ and deregistered under the Exchange Act.

Following the merger, the PrivateBank, PrivateBancorp's banking subsidiary, will be headquartered in Chicago and the PrivateBank and Holdco will constitute the primary banking, lending and wealth management platform of CIBC in the U.S.
Q:: Will my CIBC common shares acquired in the merger receive a dividend?
A: After the closing of the merger, as a holder of CIBC common shares, you will receive the same dividends on CIBC common shares that all other holders of CIBC common shares will receive with any dividend record date that occurs after the merger is completed.

Table of Contents

Former PrivateBancorp common stockholders who hold PrivateBancorp stock certificates or book entry shares will not be entitled to be paid dividends with a record date after the closing of the merger otherwise payable on the CIBC common shares into which their shares of PrivateBancorp common stock are exchangeable until they surrender their PrivateBancorp stock certificates or book entry shares according to the instructions provided to them, at which point they will receive any dividends, without interest thereon, with a record date after the closing of the merger and otherwise payable on the CIBC common shares for which their shares of PrivateBancorp common stock were exchanged.

Any such payment of dividends by CIBC would require approval by the CIBC board of directors and the board may change its dividend policy at any time. See "Comparative Per Share Market Price and Dividend Information" beginning on page 16 for a comparison of the historical dividend practices of the two companies.

Q:: Who can help answer my additional questions about the special meeting or the merger?
A:: If you have questions about the special meeting or the merger, you should contact Alliance Advisors, LLC, PrivateBancorp's proxy solicitor, toll-free at 855-976-3324 (banks and brokers call collect at 973-873-7700.

At the meeting of the board of directors of PrivateBancorp held to evaluate the proposed merger, Goldman, Sachs & Co., which we refer to as Goldman Sachs, rendered to the board of directors of PrivateBancorp its oral opinion, subsequently confirmed in writing, to the effect that, as of June 29, 2016, the date of its written opinion, and based upon and subject to the factors and assumptions set forth in Goldman Sachs' written opinion, the merger consideration to be paid to the holders (other than CIBC and its affiliates) of shares of PrivateBancorp common stock pursuant to the merger agreement was fair from a financial point of view to such holders.

Table of Contents

2016, the date of its written opinion, and based upon and subject to the factors set forth in Sandler's written opinion, the merger consideration was fair to the holders of PrivateBancorp common stock from a financial point of view. The full text of Sandler's opinion, dated June 29, 2016, is attached as Appendix C to this proxy statement. The opinion outlines the procedures followed, assumptions made, matters considered and qualifications and limitations on the review undertaken by 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 PrivateBancorp common stock are urged to read the entire opinion carefully in connection with their consideration of the proposed merger.

Sandler's opinion speaks only as of June 29, 2016, the date of the opinion. The opinion was directed to the board of directors of PrivateBancorp in connection with its consideration of the merger agreement and the proposed merger and is directed only to the fairness, from a financial point of view, of the merger consideration to the holders of PrivateBancorp common stock. Sandler's opinion does not constitute a recommendation to any holder of PrivateBancorp common stock as to how such holder of PrivateBancorp common stock should vote at any meeting of stockholders called to consider and vote upon the adoption of the merger agreement and approval of the merger. It does not address the underlying business decision of PrivateBancorp to engage in the merger, the form or structure of the merger or other transactions contemplated in the merger agreement, the relative merits of the merger as compared to any other alternative business strategies that might exist for PrivateBancorp or the effect of any other transaction in which PrivateBancorp might engage, or the fairness of the merger to any other class of securities, creditor or other constituency of PrivateBancorp. 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 or other transactions contemplated by the merger agreement by any PrivateBancorp or CIBC officer, director, or employee, or any class of such persons, if any, relative to the merger consideration to be received by any other stockholder of PrivateBancorp.

For further information, see "The Merger—Opinions of PrivateBancorp's Financial Advisors—Opinion of Sandler" beginning on page 60.

The Special Meeting (page 28)

The special meeting will be held at The PrivateBank Conference Center, 120 South LaSalle Street, Lower Level, Chicago, Illinois, on December 8, 2016 at 8:00 a.m. local time. At the special meeting, stockholders will be asked to approve the merger agreement proposal, the merger-related compensation proposal and the adjournment proposal.

PrivateBancorp's board of directors has set the close of business on October 28, 2016 as the record date for determining the holders of PrivateBancorp common stock entitled to receive notice of and to vote at the special meeting. You are entitled to receive notice of, and to vote at, the special meeting if you owned shares of PrivateBancorp common stock as of the close of business on the record date. You will have one vote on all matters properly coming before the special meeting for each share of PrivateBancorp common stock that you owned as of the close of business on the record date.

The approval of the merger agreement proposal requires the affirmative vote of a majority of the outstanding shares of PrivateBancorp common stock entitled to vote thereon. Failures to vote, abstentions and broker non-votes will have the same effect as a vote "AGAINST" the approval of the merger agreement.

On the record date, there were 79,640,010 shares of PrivateBancorp common stock outstanding and entitled to vote, held by 448 holders of record. As of the record date, the directors and executive officers of PrivateBancorp and their affiliates beneficially owned and were entitled to vote

Table of Contents

approximately 1,279,529 shares of PrivateBancorp common stock representing approximately 1.61% of the shares of PrivateBancorp common stock outstanding on that date.

No CIBC Shareholder Approval

CIBC shareholders are not required to approve the merger agreement or the issuance of CIBC common shares in connection with the merger.

Material United States Federal Income Tax Consequences (page 87)

The merger is intended to qualify as a reorganization for United States federal income tax purposes, and it is a condition to our respective obligations to complete the merger that each of CIBC and PrivateBancorp receive a legal opinion from Mayer Brown LLP and Wachtell, Lipton, Rosen & Katz, respectively, to the effect that (i) the merger, will qualify as a "reorganization" within the meaning of Section 368(a) of the Code and (ii) the merger will not result in gain recognition to the holders of PrivateBancorp common stock pursuant to Section 367(a) of the Code (assuming that, in the case of any such holder who would be treated as a "five-percent transferee shareholder" within the meaning of Treasury Regulations Section 1.367(a)-3(c)(5)(ii), such holder enters into a five-year gain recognition agreement in the form provided in Treasury Regulations Section 1.367(a)-8, as provided for in Treasury Regulations Section 1.367(a)-3(c)(1)(iii)(B), and complies with the requirements of that agreement and Treasury Regulations Section 1.367(a)-8 for avoiding the recognition of gain).

Accordingly, a PrivateBancorp common stockholder generally will recognize gain, but not loss, in an amount equal to the lesser of (i) the amount of gain realized (i.e., the excess of the sum of the amount of cash and the fair market value of the CIBC common stock received pursuant to the merger over that holder's adjusted tax basis in its shares of PrivateBancorp common stock surrendered) and (ii) the amount of cash received pursuant to the merger. Further, a PrivateBancorp common stockholder generally will recognize gain or loss with respect to cash received instead of fractional shares of CIBC common stock that the PrivateBancorp common stockholder would otherwise be entitled to receive.

It is important to note that the U.S. federal income tax consequences described above may not apply to some holders of PrivateBancorp common stock, including certain holders specifically referred to under "The Merger—Material United States Federal Income Tax Consequences" beginning on page 87. Your tax consequences will depend on your individual situation. Accordingly, we strongly urge you to consult your tax advisor for a full understanding of the tax consequences of the merger in your particular circumstances, as well as any tax consequences that may arise from the laws of any other taxing jurisdiction.

Certain Canadian Federal Income Tax Consequences (page 94)

Generally, a holder of PrivateBancorp common stock who is not, and who is not deemed to be, resident in Canada for purposes of the Canadian Tax Act will not be subject to tax under the Canadian Tax Act in respect of any capital gain realized on the disposition of PrivateBancorp common stock pursuant to the merger. See "The Merger—Certain Canadian Federal Income Tax Consequences" beginning on page 94.

Accounting Treatment (page 96)

The merger will be accounted for as a business combination applying the acquisition method of accounting for both International Financial Reporting Standards, or IFRS, and U.S. generally accepted accounting principles, or GAAP, purposes.

Table of Contents

Treatment of PrivateBancorp Equity Awards (page 106)

•: Stock Options. At the effective time, each PrivateBancorp option that is outstanding and unexercised immediately prior to the effective time shall be converted automatically into an option to purchase CIBC shares on the terms specified in the merger agreement (including that such CIBC option will have the same vesting terms as the corresponding PrivateBancorp option).
•: Restricted Stock. At the effective time, each award of restricted PrivateBancorp common stock that is outstanding and unvested immediately prior to the effective time shall be cancelled and replaced with an award of restricted CIBC common shares on the terms specified in the merger agreement (including that such CIBC restricted stock award will have the same vesting terms as the corresponding PrivateBancorp restricted stock award).
•: Restricted Stock Units. At the effective time, each PrivateBancorp restricted stock unit award that is outstanding immediately prior to the effective time shall (i) if unvested, be converted automatically into a cash-settled CIBC restricted stock unit award on the terms specified in the merger agreement (including that such CIBC restricted stock unit award shall have the same vesting terms as the corresponding PrivateBancorp restricted stock unit award), and (ii) if vested, be cancelled and converted automatically into the right to receive a cash payment equivalent in value to the merger consideration, as determined in accordance with the merger agreement, in respect of each share underlying such award plus a cash payment equal to accumulated but unpaid dividend equivalents; provided, that any such vested award that does not provide for settlement upon a change in control shall instead be converted pursuant to clause (i) above.
•: Performance Share Units. At the effective time, each PrivateBancorp performance share unit award that is outstanding immediately prior to the effective time shall (i) if unvested, be converted automatically into a CIBC cash-settled restricted stock unit award on the terms specified in the merger agreement (including that such CIBC restricted stock unit award will have the same time-based vesting terms as the corresponding PrivateBancorp performance share unit award and shall not be subject to performance-based vesting conditions), and (ii) if vested, be cancelled and converted automatically into the right to receive a cash payment equivalent in value to the merger consideration, as determined in accordance with the merger agreement, in respect of each share underlying such award plus a cash payment equal to accumulated dividend equivalents; provided, that any such vested award that does not provide for settlement upon a change in control shall instead be converted pursuant to clause (i) above. For purposes of the foregoing, the number of shares of PrivateBancorp common stock underlying each performance share unit award shall be determined by assuming that the applicable performance goals are achieved at the maximum level.
•: PrivateBancorp Deferred Units. At the effective time, each stock unit credited to an account that is deemed invested in PrivateBancorp common stock as of immediately prior to the effective time under PrivateBancorp's deferred compensation plan, shall be converted automatically into a deemed investment in CIBC common shares that will be cash-settled on the terms specified in the merger agreement.

Regulatory Approvals Required for the Completion of the Merger (page 96)

Completion of the merger is subject to the receipt of all regulatory approvals from the Board of Governors of the U.S. Federal Reserve System, referred to as the "Federal Reserve Board," the Superintendent of Financial Institutions (Canada), and the Illinois Department of Financial and Professional Regulation, Division of Banking, referred to as the "Illinois Department," as well as the receipt of all other required approvals or consents, including those the failure of which to obtain would reasonably be expected to have a material adverse effect on CIBC or PrivateBancorp. CIBC and

Table of Contents

PrivateBancorp have made such filings for approvals with the Federal Reserve Board, the Superintendent of Financial Institutions (Canada) and the Illinois Department.

Federal Reserve Board. CIBC is required to obtain the approval of the Federal Reserve Board under the Bank Holding Company Act for the acquisition of control of PrivateBancorp as a result of the merger. The U.S. Department of Justice, referred to as the "DOJ," will have an opportunity to comment during this approval process and is expected to have at least 15 days (but no more than 30 days) following the approval of the Federal Reserve Board to challenge the approval on antitrust grounds.

Bank Act. Under the Bank Act, the approval of the Superintendent of Financial Institutions (Canada) is required in order for CIBC to issue its common shares to common stockholders of PrivateBancorp as consideration for the merger and to acquire indirect control of PrivateBancorp and its subsidiaries.

Illinois Department. CIBC is required to obtain the approval of the Illinois Department under the Illinois Bank Holding Company Act of 1957, referred to as the "Illinois BHC Act," and Illinois Banking Act for the acquisition of control over PrivateBancorp as a result of the Merger.

CIBC and PrivateBancorp believe that they will be able to obtain all required regulatory approvals on a timely basis. However, there can be no assurances as to whether or when the required regulatory approvals will be obtained, or whether any such approval will contain a materially burdensome condition.

Holders of PrivateBancorp Common Stock are Entitled to Dissenters' Rights of Appraisal (page 99)

Section 262 of Delaware law provides holders of PrivateBancorp common stock with the ability to dissent from the merger and seek appraisal of their shares. A holder of PrivateBancorp common stock who properly seeks appraisal and complies with the applicable requirements under Delaware law, referred to as a "dissenting stockholder," will forego the merger consideration and instead receive a cash payment equal to the fair value of his, her or its shares of PrivateBancorp common stock in connection with the merger. Fair value would be determined by a court following an appraisal proceeding. Dissenting stockholders will not know the appraised fair value at the time such holders must elect whether to seek appraisal. The ultimate amount dissenting stockholders receive in an appraisal proceeding may be more or less than, or the same as, the amount such holders would have received under the merger agreement. A detailed description of the appraisal rights available to holders of PrivateBancorp common stock and procedures required to exercise statutory appraisal rights is included in the section entitled "The Merger—Dissenters' Rights of Appraisal for Holders of PrivateBancorp Common Stock" beginning on page 99.

To seek appraisal, a PrivateBancorp common stockholder must deliver a written demand for appraisal to PrivateBancorp before the vote on the merger agreement at the special meeting, and such stockholder must not vote in favor of the merger agreement proposal. Failure to follow exactly the procedures specified under Delaware law will result in the loss of appraisal rights.

Your Rights as a Holder of PrivateBancorp Common Stock Will Be Different from Your Rights as a Holder of CIBC Common Shares (page 126)

The conversion of your shares of PrivateBancorp common stock into CIBC common shares in the merger will result in changes from your current rights as a holder of PrivateBancorp common stock, which generally are governed by Delaware law and by PrivateBancorp's organizational documents. These rights differ from the rights you will have as a holder of CIBC common shares, which generally will be governed by the Bank Act and CIBC's organizational documents.

Some directors and executive officers of PrivateBancorp have certain interests in the merger that are different from, or in addition to, the interests of PrivateBancorp stockholders generally. These interests include, among others, potential retention benefits, severance benefits and other payments, the treatment of outstanding equity awards pursuant to the merger agreement, and rights to ongoing indemnification and insurance coverage. PrivateBancorp's board of directors was aware of these interests and considered them, among other matters, in reaching its decisions to (i) approve the merger agreement and the transactions contemplated thereby and (ii) recommend that the stockholders of PrivateBancorp approve the merger agreement proposal. See the section entitled "The Merger—Interests of PrivateBancorp's Directors and Executive Officers in the Merger" beginning on page 80 of this proxy statement/prospectus for a more detailed description of these interests.

Conditions That Must Be Satisfied or Waived for the Merger to Occur (page 117)

The respective obligations of each of CIBC and PrivateBancorp to complete the merger are conditioned upon the satisfaction, or waiver by both CIBC and PrivateBancorp, of the following conditions:

•: approval of the merger agreement proposal by the PrivateBancorp common stockholders;
•: approval for the listing on the TSX and NYSE of the CIBC common shares to be issued in the merger;
•: the effectiveness of the registration statement on Form F-4 of which this proxy statement/prospectus is a part and the absence of a stop order or proceedings initiated or threatened by the SEC for the purpose of suspending or withdrawing the effectiveness of the Form F-4; and
•: receipt of required regulatory approvals and the absence of any injunction or other legal prohibition or restraint against the merger.

The obligation of CIBC to complete the merger is subject to the satisfaction, or waiver by CIBC, of the following conditions:

•: the accuracy of the representations and warranties of PrivateBancorp as of the date of signing the merger agreement and as of the closing date of the merger, subject to applicable materiality qualifiers;
•: performance in all material respects by PrivateBancorp of the obligations required to be performed by it at or prior to the closing date of the merger; and
•: receipt by CIBC of an opinion of Mayer Brown LLP as to certain tax matters.

The obligation of PrivateBancorp to complete the merger is also subject to the satisfaction, or waiver by PrivateBancorp, of the following conditions:

•: the accuracy of the representations and warranties of CIBC as of the date of signing the merger agreement and as of the closing date of the merger, subject to applicable materiality qualifiers;
•: performance in all material respects by CIBC of the obligations required to be performed by it at or prior to the closing date of the merger; and

The Merger Agreement May be Terminated Under Certain Circumstances (page 118)

The merger agreement may be terminated at any time before the completion of the merger, whether before or after approval of the merger agreement proposal by PrivateBancorp's common stockholders, in any of the following circumstances:

•: by mutual consent of PrivateBancorp and CIBC;
•: by either PrivateBancorp or CIBC, if any of the required regulatory approvals are denied or completion of the merger has been prohibited or made illegal by a governmental entity (and the denial or prohibition is final and nonappealable);
•: by either PrivateBancorp or CIBC, if the merger has not been consummated by June 29, 2017, unless the failure to complete the merger by that date is due to the terminating party's failure to abide by the merger agreement;
•: by either PrivateBancorp or CIBC, if there is a breach by the other party that would result in the failure of the conditions of the terminating party's obligation to complete the merger, unless the breach is capable of being, and is, cured before 60 days of written notice of the breach (provided that the terminating party is not then in material breach of the merger agreement);
•: by CIBC, if PrivateBancorp or its board of directors (i) submits the merger agreement to its stockholders without a recommendation for approval, or otherwise withdraws or materially and adversely modifies its recommendation for approval (or discloses such intention), or recommends to its stockholders certain business combination proposals other than the merger agreement with CIBC, or (ii) materially breaches its obligations to call a stockholder meeting or prepare and mail the proxy statement/prospectus to its stockholders pursuant to the merger agreement or its obligations regarding the facilitation of certain types of business combinations other than as contemplated by the merger agreement; or
•: by CIBC if a tender offer or exchange offer for 20% or more of the outstanding shares of PrivateBancorp common stock is commenced (other than by CIBC or its subsidiaries), and the PrivateBancorp board of directors recommends that the stockholders of PrivateBancorp tender their shares in such tender or exchange offer or otherwise fails to recommend that such stockholders reject such tender offer or exchange offer within the 10 business day period specified in Rule 14e-2(a) under the Securities Exchange Act of 1934, as amended.

Termination Fee (page 118)

If the merger agreement is terminated under certain circumstances, including circumstances involving alternative acquisition proposals and a change in recommendation of PrivateBancorp's board of directors, PrivateBancorp may be required to pay to CIBC a termination fee equal to $150,000,000 (the "Termination Fee"). The Termination Fee could discourage other companies from seeking to acquire or merge with PrivateBancorp. For more information see "The Merger Agreement—The Merger Agreement—Effect of Termination and Termination Fee" beginning on page 118.

Litigation Related to the Merger (page 104)

Table of Contents

PrivateBancorp aided and abetted its directors' alleged breaches. Two of the actions (Parshall and Griffin) also name as defendants CIBC and Holdco, and assert that they, too, aided and abetted the directors' purported breaches. The actions broadly allege that the transaction was the result of a flawed process, that the price is unfair, and that certain provisions of the merger agreement might dissuade a potential suitor from making a competing offer, among other things. The plaintiffs in the Parshall action have filed an amended complaint, adding a claim alleging breaches of the fiduciary duty of disclosure by the directors. Plaintiffs seek injunctive and other relief, including damages.

The plaintiffs in the three actions have agreed in principle not to pursue the actions as a result of the inclusion of certain additional disclosures in this proxy statement/prospectus. PrivateBancorp and CIBC believe the demands and complaints are without merit, there are substantial legal and factual defenses to the claims asserted, and this proxy statement/prospectus disclosed all material information prior to the inclusion of these additional disclosures.

UNAUDITED COMPARATIVE PER COMMON SHARE DATA

The following tables present, as at the dates and for the periods indicated, selected historical unaudited and pro forma unaudited consolidated per share financial information for CIBC common shares and PrivateBancorp common stock. This information should be read in conjunction with, and the information is qualified in its entirety by, the consolidated financial statements and accompanying notes of CIBC and PrivateBancorp incorporated into this proxy statement/prospectus by reference. See the section entitled "Where You Can Find More Information."

The following pro forma information has been prepared in accordance with the rules and regulations of the SEC and accordingly includes the effects of purchase accounting. The pro forma information, although helpful in illustrating the financial characteristics of the combined company under one set of assumptions, does not reflect the benefits of expected cost savings, the impact of restructuring and merger-related costs, opportunities to earn additional revenue, or other factors that may result from the merger and, accordingly, the information does not attempt to predict or suggest future results. The pro forma information does reflect incremental financing expenses that are the direct result of the merger. This information is presented for illustrative purposes only. You should not rely on the pro forma combined or equivalent pro forma amounts as they are not necessarily indicative of the operating results or financial position that would have occurred if the merger had been completed as of the dates indicated, nor are they indicative of the future operating results or financial position of the combined company.

The following tables assume the issuance of 29,193,380 CIBC common shares in connection with the merger, which is the number of shares issuable by CIBC in connection with the merger assuming the merger closed on June 29, 2016 and based on the number of outstanding shares of PrivateBancorp common stock at that time. As discussed in this proxy statement/prospectus, the actual number of CIBC common shares issuable in the merger will be adjusted based on the number of shares of PrivateBancorp common stock outstanding at the completion of the merger. The pro forma data in the tables assumes that the merger occurred on November 1, 2014 for income statement purposes and on October 31, 2015 for balance sheet purposes, and that the merger is accounted for as a business combination.

(2): The pro forma combined diluted earnings per share for the year ended October 31, 2015 assumes the issuance of 902,571 additional CIBC common shares. The pro forma combined diluted earnings per share for the nine months ended July 31, 2016 assumes the issuance of 842,390 additional CIBC common shares. These adjustments relate to PrivateBancorp's stock options outstanding at the time of the merger that will be replaced with CIBC equity-based awards that will be ultimately settled with CIBC common shares. These adjustments exclude other PrivateBancorp equity-based awards that will be replaced by CIBC equity-based awards that settle in cash. The adjustments assume the merger closed on June 29, 2016, and are based on the average amount of such stock options over the relevant periods.
(3): Dividends per share have been translated into U.S. dollars based on the Bank of Canada noon exchange rate on each dividend record date. Pro forma combined dividends per common share are based solely on dividends of CIBC.
(4): Book value per common share has been translated into U.S. dollars based on the Bank of Canada noon exchange rate at the end of the period.

With respect to the table above, the CIBC pro forma combined amounts were calculated by combining (i) the CIBC historical amounts as at or for the year ended October 31, 2015 and the nine months ended July 31, 2016 (prepared in accordance with IFRS) with (ii) the PrivateBancorp historical amounts (originally prepared in accordance with U.S. GAAP), adjusted for significant differences between U.S. GAAP and IFRS, as at or for the year ended December 31, 2015 and the six months ended June 30, 2016, respectively. For purposes of calculating the pro forma combined amounts, the PrivateBancorp historical amounts have been further adjusted (on an IFRS basis) for estimated purchase accounting adjustments to be recorded in connection with the acquisition (consisting of fair value adjustments for assets acquired and liabilities assumed and adjustments for other intangible assets established, and the resulting amortization of these adjustments over appropriate periods), and other adjustments that are directly attributable to the transaction and expected to have a continuing impact on CIBC's pro forma combined financial results.

The equivalent pro forma per share information for PrivateBancorp in the following table was obtained by multiplying the above per share pro forma amounts for CIBC by 0.3657, which is the number of CIBC common shares that PrivateBancorp stockholders who receive share consideration in the merger will receive for each share of PrivateBancorp common stock, assuming that the merger was completed on June 29, 2016. Because CIBC and PrivateBancorp have different fiscal years, the equivalent pro forma data for the year ended December 31, 2015 has been compared with CIBC's fiscal year ended October 31, 2015. The PrivateBancorp historical data in the following table is presented in U.S. GAAP.

CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

From time to time, CIBC and/or PrivateBancorp make written or oral forward-looking statements within the meaning of certain securities laws, including the "safe harbor" provisions of the U.S. Private Securities Litigation Reform Act of 1995 and any applicable Canadian securities legislation. This proxy statement/prospectus, including information incorporated by reference into this document, may contain forward-looking statements, including, for example, but not limited to, statements about management expectations, strategic objectives, growth opportunities, business prospects, regulatory proceedings, transaction synergies and other benefits of the merger, and other similar matters. Forward-looking statements are not statements of historical facts and represent only CIBC's and/or PrivateBancorp's beliefs regarding future performance, which is inherently uncertain. Forward-looking statements are typically identified by words such as "believe," "expect," "foresee," "forecast," "anticipate," "intend," "estimate," "goal," "plan," and "project" and similar expressions of future or conditional verbs such as "will," "may," "should," "could" or "would."

By their very nature, forward-looking statements require us to make assumptions and are subject to inherent risks and uncertainties that give rise to the possibility that CIBC's and/or PrivateBancorp's predictions, forecasts, projections, expectations or conclusions will not prove to be accurate, that CIBC's and/or PrivateBancorp's assumptions may not be correct and that CIBC's and/or PrivateBancorp's objectives, strategic goals and priorities will not be achieved. We caution readers not to place undue reliance on these statements as a number of important factors could cause actual results to differ materially from the expectations expressed in such forward-looking statements. These factors include, but are not limited to, the possibility that the merger does not close when expected or at all because required regulatory, stockholder or other approvals are not received or other conditions to the closing are not satisfied on a timely basis or at all; that CIBC and PrivateBancorp may be required to modify the terms and conditions of the merger agreement to achieve regulatory or stockholder approval, or that the anticipated benefits of the merger are not realized as a result of such things as the strength of the economy and competitive factors in the areas where PrivateBancorp does business; general business and economic conditions in Canada, the United States and other countries in which we conduct business; the impact of the movement of the Canadian dollar relative to other currencies, particularly the U.S. dollar, British pound and Euro; the effects of changes in government monetary and other policies; the effects of competition in the markets in which we operate; the impact of changes in the laws and regulations regulating financial services and enforcement thereof (including broker-dealer, banking, insurance and securities); judicial or regulatory judgments and legal proceedings; CIBC's ability to complete the acquisition of PrivateBancorp and integrate it with CIBC successfully; the risk that expected synergies and benefits of the merger will not be realized within the expected time frame or at all; the risk of attrition of financial consultants and of assets under management, increased operating costs, customer loss, employee loss and business disruption following the merger; reputational risks; the outcome of various litigation and proceedings to which PrivateBancorp and/or CIBC is a party and the adequacy of reserves maintained therefor; and other factors that may affect future results of CIBC and PrivateBancorp, including changes in trade policies, timely development and introduction of new products and services, changes in tax laws, and technological and regulatory changes.

We caution that the foregoing list of important factors is not exhaustive and other factors could also adversely affect the completion of the merger and the future results of CIBC or PrivateBancorp. The forward-looking statements speak only as of the date of this proxy statement/prospectus, in the case of forward-looking statements contained in this proxy statement/prospectus, or the dates of the documents incorporated by reference into this proxy statement/prospectus, in the case of forward-looking statements made in those incorporated documents. When relying on our forward-looking statements to make decisions with respect to us, investors and others should carefully consider the foregoing factors and other uncertainties and potential events. Except as required by applicable law or

Table of Contents

regulation, CIBC and PrivateBancorp do not undertake to update any forward-looking statement, whether written or oral, to reflect events or circumstances after the date of this proxy statement/prospectus or to reflect the occurrence of unanticipated events.

For additional information about factors that could cause CIBC's and PrivateBancorp's results to differ materially from those described in the forward-looking statements, please see the section entitled "Risk Factors" as well as in the reports that CIBC and PrivateBancorp have filed with the SEC, described under the section entitled "Where You Can Find More Information," including CIBC's 2015 Annual Report on Form 40-F ("2015 Annual Report") and its Q3 2016 Report of Foreign Private Issuer on Form 6-K ("Q3 2016 Report") and PrivateBancorp's Annual Report on Form 10-K for the year ended December 31, 2015 and each of PrivateBancorp's subsequently filed Quarterly Reports on Form 10-Q which are available at the SEC's Internet site (www.sec.gov). CIBC's material general economic assumptions underlying certain of the forward-looking statements in this prospectus and the documents incorporated by reference herein are set out in its 2015 Annual Report under the heading "Financial performance overview—Outlook for calendar year 2016" and under the heading "Management of risk," as updated by the "A Note About Forward-Looking Statements" section in its Q3 2016 Report.

All subsequent written or oral forward-looking statements concerning the merger or other matters addressed in this proxy statement/prospectus and attributable to CIBC, PrivateBancorp or any person acting on their behalf are expressly qualified in their entirety by the cautionary statements contained or referred to in this section.

RISK FACTORS

Investing in CIBC common shares involves risks, some of which are related to the merger. In addition to the other information included or incorporated by reference in this proxy statement/prospectus, you should carefully consider the matters described below relating to the merger in deciding whether to vote for the approval of the merger agreement proposal. Although CIBC and PrivateBancorp believe that the matters described below cover the material risks related to the merger, they may not contain all of the information that is important to you in evaluating the merger. Accordingly, we urge you to read this entire proxy statement/prospectus, including the appendices and the information included or incorporated by reference in this document. Please also refer to the additional risk factors identified in the periodic reports and other documents of CIBC and PrivateBancorp incorporated by reference into this proxy statement/prospectus and listed in the section entitled "Where You Can Find More Information."

Because the market price of CIBC common shares will fluctuate, PrivateBancorp common stockholders cannot be sure of the value of the merger consideration they will receive.

Upon completion of the merger, each share of PrivateBancorp common stock will be converted into merger consideration consisting of cash consideration and share consideration in the form of CIBC common shares, pursuant to the terms of the merger agreement.

If you are a holder of PrivateBancorp common stock, the value of the merger consideration constituting common shares of CIBC that you will receive will fluctuate based on the market price of CIBC common shares. The value of the merger consideration constituting common shares of CIBC that a PrivateBancorp stockholder will receive for each share of PrivateBancorp common stock will depend on the market price of CIBC common shares at the time PrivateBancorp stockholder receives the CIBC common shares (following completion of the merger). The closing price of CIBC common shares on the date that the merger is completed may vary from the closing price of CIBC common shares on the date CIBC and PrivateBancorp announced the merger, on the date that this document is being mailed to each of the PrivateBancorp stockholders, on the date of the special meeting of PrivateBancorp stockholders, or on any other date. Any change in the market price of CIBC common shares prior to completion of the merger will affect the value of the merger consideration that PrivateBancorp stockholders will receive upon completion of the merger. Stock price changes may result from a variety of factors, including general market, economic and political conditions, changes in our respective businesses, operations and prospects, factors influencing the Canadian dollar/U.S. dollar exchange rate and regulatory considerations, among other things. Many of these factors are beyond the control of CIBC and PrivateBancorp. Accordingly, at the time of the special meeting, PrivateBancorp stockholders will not know or be able to calculate the value of the CIBC common shares they would receive upon completion of the merger.

In addition, because shares traded on the TSX are traded in Canadian dollars, the value of CIBC common shares on a U.S. dollar basis may decline compared to PrivateBancorp common stock, even if the share price of CIBC common shares on the TSX does not decline.

Upon completion of the merger, holders of PrivateBancorp common stock will become holders of CIBC common shares and the market price for CIBC common shares may be affected by factors different from those that historically have affected PrivateBancorp.

Upon completion of the merger, holders of PrivateBancorp common stock will become holders of CIBC common shares. CIBC's businesses differ from those of PrivateBancorp, and accordingly the results of operations of CIBC will be affected by some factors that are different from those currently affecting the results of operations of PrivateBancorp. For a discussion of the businesses of PrivateBancorp and CIBC and of some important factors to consider in connection with those

Table of Contents

businesses, see the documents incorporated by reference in this proxy statement/prospectus and referred to under "Where You Can Find More Information."

Combining the two companies may be more difficult, costly or time-consuming than expected.

CIBC and PrivateBancorp have operated and, until the completion of the merger, will continue to operate, independently. The success of the merger, including anticipated benefits and cost savings, will depend, in part, on CIBC's ability to successfully integrate PrivateBancorp's operations in a manner that results in various benefits, including, among other things, deposit and revenue synergies, an expanded reach and operating efficiencies, and that does not materially disrupt existing client relationships nor result in decreased revenues due to loss of clients. Additionally, a loss of key PrivateBancorp personnel could cause an interruption of, or loss of momentum in, the activities of one or more of the surviving corporation's businesses or inconsistencies in standards, controls, procedures and policies that adversely affect the ability of CIBC or PrivateBancorp to and maintain and develop relationships with existing and prospective clients as well as employees. The diversion of management's attention and any delays or difficulties encountered in connection with the merger and the integration of PrivateBancorp's operations could have an adverse effect on the business, financial condition, operating results and prospects of CIBC after the merger.

The success of the combined entity following the merger will depend in part on the ability of CIBC to integrate the two businesses and grow the U.S. banking platform. If CIBC experiences difficulties in this process, including those listed above, CIBC may fail to realize the anticipated benefits of the merger in a timely manner or at all. 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 CIBC's business, financial condition, operating results and prospects.

Among the factors considered by the boards of directors of CIBC and PrivateBancorp in connection with their respective approvals of the merger agreement were the benefits that could result from the merger. We cannot give any assurance that these benefits will be realized within the time periods contemplated or at all.

Some directors and executive officers of PrivateBancorp have interests in the merger that may differ from the interests of PrivateBancorp stockholders generally, including, if the merger is completed, the receipt of financial and other benefits.

In considering the recommendation of PrivateBancorp's board of directors, you should be aware that some of its directors and executive officers have interests in the merger that are different from, or in addition to, those of PrivateBancorp stockholders generally. These interests include, among others, retention awards, potential severance benefits and other payments, the treatment of outstanding equity awards pursuant to the merger agreement, the employment agreement entered into by CIBC and PrivateBancorp's President & Chief Executive Officer, Larry D. Richman, and rights to ongoing indemnification and insurance coverage. These interests are described in more detail in the section entitled "The Merger—Interests of PrivateBancorp's Directors and Executive Officers in the Merger."

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

The merger agreement contains provisions that may discourage a third party from submitting an acquisition proposal to PrivateBancorp that might result in greater value to PrivateBancorp's common stockholders than the merger, or may result in a potential competing acquirer proposing to pay a lower per share price to acquire PrivateBancorp than it might otherwise have proposed to pay. These provisions include a general prohibition on PrivateBancorp from soliciting or, subject to certain

Table of Contents

exceptions relating to the exercise of fiduciary duties by the PrivateBancorp board of directors, entering into discussions with any third party regarding, any acquisition proposal or offers for competing transactions. In addition, PrivateBancorp may be required to pay CIBC a termination fee of $150 million in certain circumstances involving acquisition proposals for competing transactions. See the sections entitled "The Merger Agreement—Termination" and "The Merger Agreement—Effect of Termination and Termination Fee."

If the merger is not consummated by June 29, 2017, either CIBC or PrivateBancorp may choose not to proceed with the merger.

Either CIBC or PrivateBancorp may terminate the merger agreement if the merger has not been completed by June 29, 2017, the date of the first anniversary of the merger agreement, unless the failure of the merger to be completed has resulted from the material failure of the party seeking to terminate the merger agreement to perform its obligations. See the section entitled "The Merger Agreement—Termination."

Termination of the merger agreement or failure to complete the merger at all, or a material delay in completing the merger, could negatively impact the stock price and the future business and financial results of PrivateBancorp, and in certain circumstances could result in the payment by PrivateBancorp of a termination fee.

If the merger is not completed for any reason, including as a result of PrivateBancorp stockholders declining to approve the merger agreement or the failure of the parties to obtain the required regulatory approvals, or if there is a material delay in completing the merger, the ongoing business of PrivateBancorp may be adversely affected. In such case, PrivateBancorp would be subject to a number of risks, including the following:

•: PrivateBancorp may experience negative reactions from the financial markets, including negative impacts on its stock price;
•: PrivateBancorp may experience negative reactions from its clients, vendors and employees, and if there is a material delay in completing the merger, PrivateBancorp may find it more challenging to retain its clients and key employees due to the perceived uncertainty about the transaction;
•: PrivateBancorp will have incurred substantial expenses and will be required to pay certain costs relating to the merger, whether or not the merger is completed;
•: the merger agreement places certain restrictions on the conduct of PrivateBancorp's businesses prior to completion of the merger. Such restrictions, the waiver of which is subject to the consent of CIBC (not to be unreasonably withheld), may prevent or delay PrivateBancorp from making certain acquisition, entering into new lines of business, entering into or modifying material contracts or taking certain other specified actions during the pendency of the merger (see the section entitled "The Merger Agreement—Covenants and Agreements—Conduct of Businesses Prior to the Completion of the Merger" for a description of the restrictive covenants applicable to PrivateBancorp); and
•: matters relating to the merger (including integration planning) will require substantial commitments of time and resources by PrivateBancorp management, which would otherwise have been devoted to other opportunities that may have been beneficial to PrivateBancorp as an independent company.

In addition to the above risks, if the merger agreement is terminated and PrivateBancorp's board of directors seeks another merger or business combination, PrivateBancorp stockholders cannot be certain that PrivateBancorp will be able to find a party willing to offer equivalent or more attractive consideration than the consideration CIBC has agreed to provide in the merger. If the merger

Table of Contents

agreement is terminated under certain circumstances, PrivateBancorp may be required to pay a termination fee of $150 million to CIBC. See the section entitled "The Merger Agreement—Effect of Termination and Termination Fee."

The merger is subject to the receipt of consents and approvals from government entities that may not be obtained and may impose conditions that could have an adverse effect on CIBC or could prevent or delay completion of the merger.

Before the transactions contemplated in the merger agreement may be completed, various approvals must be obtained from the Federal Reserve Board, the Superintendent of Financial Institutions (Canada), the Illinois Department, Division of Banking, and other governmental authorities. In determining whether to grant these approvals, the regulators consider a variety of factors, including the regulatory standing of each party and the factors described under "The Merger—Regulatory Matters Related to the Merger" and "The Merger Agreement—Conditions to the Merger." An adverse development in either party's regulatory standing or these factors could result in an inability to obtain one or more approvals or delay their receipt. These governmental entities may impose conditions, limitations or costs or place restrictions on the conduct of CIBC or the surviving entity after the closing as a condition to the granting of such approvals or require changes to the terms of the merger. Such conditions or changes and the process of obtaining regulatory approvals could have the effect of delaying completion of the merger or of imposing additional costs or limitations on CIBC following the merger, any of which might have an adverse effect on the surviving corporation following the merger. The regulatory approvals may not be received at any time, may not be received in a timely fashion, and may contain conditions on the completion of the merger that adversely affect the surviving corporation's business following the closing, or which are not anticipated or cannot be met.

In addition, one of the conditions for closing is that no regulatory approval required for the merger result in the imposition of a condition or restriction that would reasonably be likely to have a material and adverse effect on CIBC and its subsidiaries, taken as a whole (with such materiality measured on a scale relative to PrivateBancorp and its subsidiaries, taken as a whole).

Certain rights of holders of PrivateBancorp common stock will change as a result of the merger.

Following completion of the merger, holders of PrivateBancorp common stock will no longer be stockholders of PrivateBancorp, a Delaware corporation, but will instead be shareholders of CIBC, a Canadian chartered bank. There will be certain differences between your current rights as a stockholder of PrivateBancorp, on the one hand, and the rights to which you will be entitled as a shareholder of CIBC, on the other hand. For a more detailed discussion of the differences in the rights of stockholders of PrivateBancorp and CIBC, see "Comparison of Rights of CIBC Shareholders and PrivateBancorp Stockholders."

If the merger fails to qualify as a "reorganization" within the meaning of Section 368(a) of the Code, PrivateBancorp stockholders may be required to recognize gain or loss on the exchange of their shares of PrivateBancorp common stock in the merger for U.S. federal income tax purposes.

CIBC and PrivateBancorp have structured the merger to qualify as a reorganization within the meaning of Section 368(a) of the Code. Neither CIBC nor PrivateBancorp intends to request any ruling from the U.S. Internal Revenue Service, referred to as the "IRS," as to the tax consequences of the exchange of shares of PrivateBancorp common stock for CIBC common shares in the merger. If the merger fails to qualify as a reorganization, a PrivateBancorp stockholder would generally recognize gain or loss for U.S. federal income tax purposes on each share of PrivateBancorp common stock exchanged in the merger in an amount equal to the difference between that stockholder's tax basis in such share and the fair market value of the CIBC common shares and/or cash the PrivateBancorp stockholder receives or may receive in exchange for each such share of PrivateBancorp common stock. You are

Table of Contents

urged to consult with your own tax advisor regarding the proper reporting of the amount and timing of such gain or loss. See "The Merger—Material United States Federal Income Tax Consequences."

Holders of PrivateBancorp common stock will have a reduced ownership and voting interest after the merger and will exercise less influence over management of the combined organization.

Holders of PrivateBancorp common stock currently have the right to vote in the election of PrivateBancorp's board of directors and on other matters affecting PrivateBancorp. Upon the completion of the merger, each holder of PrivateBancorp common stock that receives CIBC common shares will become a shareholder of CIBC with a percentage ownership of the combined organization that is much smaller than the stockholder's percentage ownership of PrivateBancorp. It is expected that the former holders of PrivateBancorp common stock as a group will receive shares in the merger constituting approximately 7% of the outstanding CIBC common shares immediately after the merger. Because of this, holders of PrivateBancorp common stock will have significantly less influence on the management and policies of CIBC than they now have on the management and policies of PrivateBancorp.

PrivateBancorp will be subject to business uncertainties and contractual restrictions while the merger is pending.

Uncertainty about the effect of the merger on employees and clients may have an adverse effect on PrivateBancorp and consequently on CIBC. These uncertainties may impair PrivateBancorp's ability to attract, retain and motivate key personnel, and could cause clients and others that deal with PrivateBancorp to seek to change existing business relationships with PrivateBancorp. Retention of certain employees may be challenging during the pendency of the merger, as certain employees may experience uncertainty about their future roles. If key employees depart because of issues relating to the uncertainty and difficulty of integration or a desire not to remain with the business, CIBC's business following the merger could be negatively impacted. In addition, until the merger occurs, the merger agreement restricts PrivateBancorp from making certain acquisitions and taking other specified actions without the consent of CIBC. These restrictions may prevent PrivateBancorp from pursuing attractive business opportunities that may arise prior to the completion of the merger. See "The Merger Agreement—Covenants and Agreements" for a description of the restrictive covenants applicable to PrivateBancorp.

CIBC's consolidated results of operations may be negatively impacted by foreign currency fluctuations.

A portion of CIBC's consolidated revenues following the merger will be earned in non-Canadian currencies, primarily U.S. dollars. The revenues that are earned in currencies other than Canadian dollars are subject to unpredictable fluctuations if the values of non-Canadian currencies change relative to the Canadian dollar. Such fluctuations could decrease CIBC's revenues earned in non-Canadian currencies and have a material adverse impact on its business.

CIBC expects to maintain its status as a "foreign private issuer" in the U.S. and thus will be exempt from a number of rules under the U.S. Securities Exchange Act of 1934, as amended, and will be permitted to file less information with the SEC than a company incorporated in the U.S.

As a "foreign private issuer," CIBC is exempt from rules under the U.S. Securities Exchange Act of 1934, as amended, referred to as the "Exchange Act," that impose disclosure requirements, as well as procedural requirements, for proxy solicitations under Section 14 of the Exchange Act. In addition, CIBC's officers, directors and principal shareholders are exempt from the reporting and "short-swing" profit recovery provisions of Section 16 of the Exchange Act. In addition, CIBC is permitted, under a multi-jurisdictional disclosure system adopted by the United States and Canada, to prepare its disclosure documents filed under the Exchange Act in accordance with Canadian disclosure

requirements, including preparing its financial statements in accordance with IFRS, which differ in some respects from U.S. GAAP. As a result, following the merger, holders of PrivateBancorp common stock may have less readily available access to information about the financial performance and business of CIBC as compared to PrivateBancorp, or such information may be presented differently.

CIBC is chartered under the laws of Canada and a substantial portion of its assets are, and many of its directors and officers reside, outside of the United States. As a result, it may not be possible for shareholders to enforce civil liability provisions of the securities laws of the United States in Canada.

CIBC is chartered under the laws of Canada. A substantial portion of CIBC's assets are located outside the United States, and many of CIBC's directors and officers and some of the experts named in this proxy statement/prospectus are residents of jurisdictions outside of the United States. As a result, it may be difficult for investors to effect service within the United States upon CIBC and those directors, officers and experts, or to realize in the United States upon judgments of courts of the United States predicated upon civil liability of CIBC and such directors, officers or experts under the United States federal securities laws. There is uncertainty as to the enforceability in Canada by a court in original actions, or in actions to enforce judgments of United States courts, of the civil liabilities predicated upon the United States federal securities laws.

Certain market activities of CIBC and its affiliates may affect the value of CIBC common shares.

CIBC and its affiliates engage in market making, derivatives and structured notes hedging, brokerage and facilitation trading, asset management, index-related adjustments, investment fund management, plan-related activities, banking-related activities, estates and trusts services, custody-related activities, stock borrowing, lending and taking of collateral, involving CIBC common shares outside the United States (and, to a limited extent, within the United States). Please read the section entitled "CIBC Market Activities Involving CIBC Common Shares" for more information. Such activities could have the effect of influencing the market price of CIBC common shares.

The United Kingdom's vote to leave the European Union may adversely affect CIBC's and/or PrivateBancorp's results and financial condition.

On June 23, 2016, the United Kingdom (UK) held a referendum to decide on the UK's membership in the European Union. The UK vote was to leave the European Union. There are a number of uncertainties in connection with the future of the UK and its relationship with the European Union. The negotiation of the UK's exit terms is likely to take a number of years. Until the terms and timing of the UK's exit from the European Union are clearer, it is not possible to determine the impact that the referendum, the UK's departure from the European Union and/or any related matters may have on CIBC's and/or PrivateBancorp's results and financial condition. As such, no assurance can be given that such matters would not adversely affect the market value or the performance of CIBC's common shares or shares of PrivateBancorp common stock.

Litigation relating to the merger could require us to incur significant costs and suffer management distraction, as well as delay and/or enjoin the merger.

Griffin) also name as defendants CIBC and Holdco, and assert that they, too, aided and abetted the directors' purported breaches. The actions broadly allege that the transaction was the result of a flawed process, that the price is unfair, and that certain provisions of the merger agreement might dissuade a potential suitor from making a competing offer, among other things. The plaintiffs in the Parshall action have filed an amended complaint, adding a claim alleging breaches of the fiduciary duty of disclosure by the directors. Plaintiffs seek injunctive and other relief, including damages.

PrivateBancorp and CIBC also could be subject to additional demands or litigation related to the merger whether or not the merger is consummated. Although both PrivateBancorp and CIBC believe that the demands are unwarranted and that there are substantial legal and factual defenses to the claims, such actions create additional uncertainty relating to the merger and responding to such demands and defending such actions is costly and distracting to management. Although there can be no assurance as to the ultimate outcomes of the demands or any subsequent litigation, neither PrivateBancorp nor CIBC believes that their resolution will have a material adverse effect on its respective financial position, results of operations or cash flows.

The opinions received by the PrivateBancorp board of directors from Goldman Sachs and Sandler have not been, and are not expected to be, updated to reflect any changes in circumstances that may have occurred since the dates of the opinions.

The opinions delivered to the PrivateBancorp board of directors by Goldman Sachs and Sandler, financial advisors to PrivateBancorp, as to the fairness, from a financial point of view, of the merger consideration to be received by the holders of PrivateBancorp common stock in the proposed merger speak only as of the date of the opinions, which is June 29, 2016. Changes in the operations and prospects of CIBC or PrivateBancorp, general market and economic conditions and other factors which may be beyond the control of CIBC and PrivateBancorp may have altered the value of CIBC or PrivateBancorp or the sale prices of CIBC common shares as of the date of this proxy statement/prospectus, or may alter such values and sale prices by the time the merger is completed. Neither Goldman Sachs nor Sandler has any obligation to update, revise or reaffirm its opinion to reflect subsequent developments and neither has done so. PrivateBancorp does not currently anticipate asking Goldman Sachs or Sandler to update its opinion to address the fairness of the merger consideration from a financial point of view at the time the merger is completed. The PrivateBancorp board of directors' recommendation that PrivateBancorp common stockholders vote "FOR" approval of the merger agreement proposal, however, is made as of the date of this proxy statement/prospectus. See "The Merger—Opinions of PrivateBancorp's Financial Advisors," and Appendix B and Appendix C to this proxy statement/prospectus.

THE SPECIAL MEETING

This section contains information for holders of PrivateBancorp common stock about the special meeting that PrivateBancorp has called to allow its common stockholders to consider and approve the merger agreement. PrivateBancorp is mailing this proxy statement/prospectus to its common stockholders on or about November 2, 2016. Together with this proxy statement/prospectus, PrivateBancorp is sending a notice of the special meeting and a form of proxy that PrivateBancorp's board of directors is soliciting for use at the special meeting and at any adjournments or postponements of the special meeting.

This proxy statement/prospectus is also being furnished by CIBC to stockholders of PrivateBancorp as a prospectus in connection with the issuance of CIBC common shares upon completion of the merger.

Time, Place and Purpose of the Special Meeting

This proxy statement/prospectus is being furnished to PrivateBancorp common stockholders as part of the solicitation of proxies by the PrivateBancorp board of directors for use at the special meeting to be held on December 8, 2016, at 8:00 a.m. local time, at The PrivateBank Conference Center, 120 South LaSalle Street, Lower Level, Chicago, Illinois, or at any postponement or adjournment thereof.

At the special meeting, PrivateBancorp stockholders will be asked to consider and vote upon the following proposals:

1.: a proposal to adopt the merger agreement (the "merger agreement proposal");
2.: a proposal to approve, by advisory (non-binding) vote, certain compensation that may be paid or become payable to PrivateBancorp's named executive officers in connection with the merger (the "merger-related compensation proposal") and
3.: a proposal for adjournment of the special meeting, if necessary or appropriate, to solicit additional proxies if there are insufficient votes at the time of the special meeting to adopt the merger agreement (the "adjournment proposal").

Merger Agreement Proposal

PrivateBancorp common stockholders must adopt the merger agreement by approving the merger agreement proposal in order for the merger to occur. A copy of the merger agreement is attached as Appendix A to this proxy statement/prospectus, and you are encouraged to read the merger agreement carefully and in its entirety, as well as the other information in this proxy statement/prospectus.

Merger-Related Compensation Proposal

Pursuant to Section 14A of the Exchange Act and Rule 14a-21(c) thereunder, PrivateBancorp is providing its common stockholders with a separate advisory (non-binding) vote to approve the merger-related compensation that may be paid or become payable to its named executive officers that is based on or otherwise relates to the merger, as described in the table in the section entitled "Interests of PrivateBancorp's Directors and Executive Officers in the Merger—Quantification of Potential Payments and Benefits to PrivateBancorp's Named Executive Officers in Connection with the Merger," including the footnotes to the table and related narrative discussion.

Stockholders are being asked to approve the following resolution on an advisory (non-binding) basis:

"RESOLVED, that the compensation that may be paid or become payable to PrivateBancorp's named executive officers in connection with the merger, and the agreement or understandings pursuant to which such compensation may be paid or become payable, in each case as disclosed

Table of Contents

pursuant to Item 402(t) of Regulation S-K in the table in the section entitled "Interests of PrivateBancorp's Directors and Executive Officers in the Merger—Quantification of Potential Payments and Benefits to PrivateBancorp's Named Executive Officers in Connection with the Merger," including the footnotes to the table and the related narrative discussion, is hereby APPROVED."

The vote on the merger-related compensation proposal is advisory in nature and, therefore, is not binding on PrivateBancorp or on CIBC or the boards of directors or the compensation committees of PrivateBancorp or CIBC, regardless of whether the merger agreement proposal is approved.

Approval of this advisory (non-binding) proposal is not a condition to completion of the merger. If the merger is completed, the merger-related compensation may be paid to PrivateBancorp's named executive officers to the extent payable in accordance with the terms of their compensation agreements and arrangements, and the outcome of this advisory (non-binding) vote will not affect PrivateBancorp's or CIBC's obligations to make these payments even if PrivateBancorp common stockholders do not approve, by advisory (non-binding) vote, this proposal.

The vote on the merger-related compensation proposal is separate from the vote to adopt the merger agreement. You may vote "AGAINST" the merger-related compensation proposal and "FOR" approval of the merger agreement proposal and vice versa. You also may abstain from this proposal and vote on the merger agreement proposal and vice versa.

Adjournment Proposal

PrivateBancorp common stockholders are being asked to grant authority to proxy holders to vote in favor of one or more adjournments of the special meeting, if necessary or appropriate, to solicit additional proxies if there are insufficient votes at the time of the special meeting to adopt the merger agreement. If this proposal is approved, the special meeting could be successively adjourned to any date. In accordance with the PrivateBancorp by-laws, a vote on adjournment of the special meeting may be taken in the absence of a quorum. PrivateBancorp does not intend to call a vote on adjournment of the special meeting to solicit additional proxies if the merger agreement proposal is approved at the special meeting. Additionally, pursuant to the merger agreement, PrivateBancorp is only required to adjourn the special meeting to solicit additional proxies two times.

Recommendations of the PrivateBancorp Board of Directors

The PrivateBancorp board of directors recommends that you vote "FOR" the merger agreement proposal, "FOR" the merger-related compensation proposal and "FOR" the adjournment proposal.

Record Date

PrivateBancorp has set the close of business on October 28, 2016 as the record date for the special meeting, and only holders of record of PrivateBancorp common stock on the record date are entitled to vote at the special meeting or any postponements or adjournments thereof. You are entitled to receive notice of, and to vote at, the special meeting if you owned shares of PrivateBancorp common stock, including shares in respect of PrivateBancorp restricted stock awards, as of the close of business on the record date. You will have one vote on all matters properly coming before the special meeting for each share of PrivateBancorp common stock that you owned as of the close of business on the record date.

Table of Contents

As of the record date, October 28, 2016, there were 79,640,010 shares of PrivateBancorp common stock outstanding and entitled to vote, held by 448 holders of record. As of October 28, 2016, the directors and executive officers of PrivateBancorp and their affiliates beneficially owned and were entitled to vote approximately 1,279,529 shares of PrivateBancorp common stock representing approximately 1.61% of the shares of PrivateBancorp common stock outstanding on that date.

As of the record date, October 28, 2016, CIBC did not beneficially own any shares of PrivateBancorp's common stock.

Quorum Required

The presence, in person or represented by proxy, of holders of a majority of the aggregate voting power of the issued and outstanding shares of PrivateBancorp common stock entitled to vote at the special meeting constitutes a quorum for the purposes of the special meeting.

Abstentions, which occur when you vote "ABSTAIN" with respect to one or more proposals, will be considered present for purposes of establishing a quorum.

PrivateBancorp common shares held in "street name" with respect to which the beneficial owner fails to give voting instructions to the broker, bank, nominee or other holder of record, and shares of PrivateBancorp common stock with respect to which the beneficial owner otherwise fails to vote, will not be considered present and entitled to vote at the special meeting for the purpose of determining the presence of a quorum. Failures to vote will not be considered present for purposes of establishing a quorum.

Vote Required

The approval of the merger-related compensation proposal requires the affirmative vote of the holders of a majority of shares of PrivateBancorp common stock present in person or represented by proxy and entitled to vote thereon; however, such vote is advisory (non-binding) only. If your shares of PrivateBancorp common stock are present at the special meeting but are not voted on the proposal, or if you vote to abstain on the proposal, each will have the effect of a vote "AGAINST" the merger-related compensation proposal. If you fail to submit a proxy and fail to attend the special meeting, or if you do not instruct your bank, brokerage firm or other nominee to vote your shares of PrivateBancorp common stock in favor of the proposal, your shares of PrivateBancorp common stock will not be voted, but this will not have an effect on the advisory (non-binding) vote to approve the merger-related compensation proposal except to the extent it results in there being insufficient shares present at the meeting to establish a quorum.

The approval of the adjournment proposal requires the affirmative vote of the holders of a majority of shares of PrivateBancorp common stock present in person or represented by proxy and entitled to vote thereon, whether or not a quorum is present. If your shares of PrivateBancorp common stock are present at the special meeting but are not voted on the proposal, or if you vote to abstain on the proposal, each will have the effect of a vote "AGAINST" the adjournment proposal. If you fail to submit a proxy and fail to attend the special meeting or if your shares of PrivateBancorp common stock are held through a bank, brokerage firm or other nominee and you do not instruct your bank, brokerage firm or other nominee to vote your shares of PrivateBancorp common stock, your shares of PrivateBancorp common stock will not be voted, but this will not have an effect on the approval of the adjournment proposal.

How to Vote

Stockholders of Record

If your shares of PrivateBancorp common stock are registered directly in your name with the transfer agent of PrivateBancorp, Computershare, you are considered, with respect to those shares of PrivateBancorp common stock, the stockholder of record. If you are a stockholder of record, this proxy statement/prospectus and the enclosed proxy card have been sent directly to you by PrivateBancorp.

If you are a stockholder of record, you may have your shares of PrivateBancorp common stock voted on matters presented at the special meeting in the following ways:

•: by touch-tone telephone or over the Internet, by accessing the telephone number or Internet website specified on the enclosed proxy card. The control number provided on your proxy card is designed to verify your identity when voting by telephone or by Internet. Proxies delivered over the Internet or by telephone must be submitted by 11:59 pm, Eastern Time, on the day before the special meeting. Please be aware that if you vote by telephone or over the Internet, you may incur costs such as telephone and Internet access charges for which you will be responsible;
•: by completing, signing, dating and returning the enclosed proxy card in the accompanying prepaid reply envelope, which must be received before the shares are voted at the special meeting; or
•: in person—you may attend the special meeting and cast your vote there. Attendance at the special meeting will not, in and of itself, constitute a vote or a revocation of a prior proxy, however.

Beneficial Holders

If your shares of PrivateBancorp common stock are held through a bank, brokerage firm or other nominee, you are considered the beneficial owner of shares of PrivateBancorp common stock held in "street name." In that case, this proxy statement/prospectus has been forwarded to you by your bank, brokerage firm or other nominee who is considered, with respect to those shares of PrivateBancorp common stock, the stockholder of record. As the beneficial owner, you have the right to direct your bank, brokerage firm or other nominee how to vote your shares by following their instructions for voting.

In accordance with the rules of the NASDAQ, brokers, banks and other nominees who hold shares of common stock in "street name" for their customers do not have discretionary authority to vote the shares with respect to the proposal to adopt the merger agreement, the advisory (non-binding) proposal to approve specified compensation that may be paid or become payable to the named executive officers of the Company in connection with the merger, or the adjournment of the special meeting, if necessary or appropriate, including to solicit additional proxies. Accordingly, if brokers, banks or other nominees do not receive specific voting instructions from the beneficial owner of such shares, they may not vote such shares with respect to these proposals. Under such circumstance, a "broker non-vote" would arise. Broker non-votes, if any, will not be considered present at the special meeting for purposes of determining whether a quorum is present at the special meeting, will have the same effect as a vote "AGAINST" the proposal to adopt the merger agreement and, assuming a quorum is present, will have no effect on the advisory (non-binding) proposal on executive compensation payable to the PrivateBancorp's named executive officers in connection with the merger or the adjournment proposal. Thus, for shares of common stock held in "street name," only shares of common stock affirmatively voted "FOR" the proposal to adopt the merger agreement will be counted as a vote in favor of such proposal.

Savings Plan Participants

If you participate in the PrivateBancorp, Inc. Savings, Retirement and Employee Stock Ownership Plan (the "KSOP"), and your plan account had an investment in shares of PrivateBancorp common stock as of the record date, you must provide voting instructions to the plan trustee, Delaware Charter Guarantee & Trust Company d/b/a Principal Trust Company (the "Trustee"), by the Internet, telephone, or executed voting direction card for your shares to be voted according to your instructions.

If voting instructions are not received by the Trustee with respect to shares of PrivateBancorp common stock allocated to your plan account in the KSOP, such shares will be voted by the Trustee in the same ratio as the shares for which voting directions have been received by the Trustee and in accordance with the Employee Retirement Income Security Act. The deadline to provide voting directions for shares allocated to your plan account in the KSOP is December 5, 2016 at 1:00 a.m., Central time, which, for administrative reasons, is earlier than the deadline for voting PrivateBancorp shares not held through the KSOP. You will not be able to submit or change voting directions after this deadline. If you own shares both through and outside of the KSOP, you will be required to vote those shares separately.

Other Voting Instructions

Please refer to the instructions on your proxy or voting instruction card to determine the deadlines for voting over the Internet or by telephone. If you submit a proxy by mailing a proxy card, your proxy card should be mailed in the accompanying prepaid reply envelope, and your proxy card must be filed with the Secretary of PrivateBancorp by the time the special meeting begins. Please do not send in your stock certificates with your proxy card. When the merger is completed, a separate letter of transmittal will be mailed to you that will enable you to receive the merger consideration in your elected form in exchange for your stock certificates.

If you vote by proxy, the individuals named on the enclosed proxy card (each of them, with full power of substitution) will vote your shares of PrivateBancorp common stock in the way that you indicate. When completing the Internet or telephone processes or the proxy card, you may specify whether your shares of PrivateBancorp common stock should be voted "FOR" or "AGAINST" or to "ABSTAIN" from voting on all, some or none of the specific items of business to come before the special meeting.

If you properly sign your proxy card but do not mark the boxes showing how your shares of PrivateBancorp common stock should be voted on a matter, the shares of PrivateBancorp common stock represented by your properly signed proxy will be voted "FOR" the merger agreement proposal, "FOR" the merger-related compensation proposal and "FOR" the adjournment proposal.

If you hold your shares in more than one brokerage account, or if you hold your shares in multiple ways (as a record holder, beneficial holder and/or KSOP participant), you may have received more than one set of proxy materials. It is important that you return all proxy cards and voting instruction cards to make sure all your shares are voted.

If you have any questions or need assistance voting your shares, please contact Alliance Advisors, LLC, PrivateBancorp's proxy solicitor, at 855-976-3324.

Revocations

Stockholders of Record

If you are a stockholder of record, you may change your vote at any time before your shares are voted in any of the following ways:

•: by voting via Internet or telephone at a later date (in which case only the later-submitted proxy will be counted and the earlier-submitted proxy will be revoked);
•: by completing, signing, dating and returning a new proxy card, which must be received before the shares are voted at the special meeting (in which case only the later-submitted proxy will be counted and the earlier-submitted proxy will be revoked);
•: by filing a timely written notice of revocation with the Corporate Secretary of PrivateBancorp at PrivateBancorp, Inc., Attn: Corporate Secretary, 120 South LaSalle Street, Chicago, Illinois 60603; or
•: in person—you may attend the special meeting and cast your vote there (in which case any earlier-submitted proxy will be revoked). Attendance at the special meeting will not, in and of itself, constitute a vote or a revocation of a prior proxy.

Unless you decide to attend the meeting and vote your shares in person after you have submitted a prior proxy, we recommend that you revoke or amend your prior instructions in the same way you initially gave them—that is, by telephone, Internet or in writing. This will help to ensure that your shares are voted the way you have finally determined you wish them to be voted. If you revoke by mail or by using the telephone or Internet voting options, PrivateBancorp must receive the revocation before the special meeting begins. If you choose to revoke by mail, please make sure you have provided enough time for the replacement proxy to reach PrivateBancorp. Once the special meeting begins, you can only revoke your proxy in person. Once the polls close at the special meeting, the right to revoke ends.

Beneficial Holders

If you are a beneficial holder, you may change your vote by following the instructions provided to you by your bank, brokerage firm or other nominee and submit new voting instructions to such bank, brokerage firm or other nominee.

Savings Plan Participants

If you hold PrivateBancorp common stock through the KSOP, you must follow the instructions provided to you by the Trustee and submit new voting instructions to the Trustee. The deadline for such revocations is December 5, 2016, at 1:00 a.m., Central time. You will not be able to change your vote after this deadline.

PrivateBancorp has agreed to pay such proxy solicitor approximately $12,500 plus reasonable out-of-pocket expenses for such services and also will indemnify it against certain claims, costs, damages, liabilities, judgments and expenses.

THE MERGER

The following discussion contains material information about the merger and certain terms of the merger agreement. You should also read in its entirety the section entitled "The Merger Agreement" for a discussion of additional material information about the terms of the merger agreement. The discussion is subject to, and qualified in its entirety by reference to, the merger agreement, a copy of which is attached as Appendix A to this proxy statement/prospectus and incorporated herein by reference. We urge you to read carefully this entire proxy statement/prospectus, including the merger agreement, for a more complete understanding of the merger.

Terms of the Merger

Transaction Structure

CIBC's and PrivateBancorp's boards of directors have approved the merger agreement. The merger agreement provides for the acquisition of PrivateBancorp by CIBC through the merger of PrivateBancorp with and into Holdco, with Holdco continuing as the surviving entity. Upon completion of the merger, the separate corporate existence of PrivateBancorp will cease. The PrivateBank and Trust Company ("PrivateBank"), which is currently a wholly-owned subsidiary of PrivateBancorp, will be a wholly-owned subsidiary of Holdco upon completion of the merger.

Merger Consideration

Under the terms and subject to the conditions of the merger agreement, at the effective time of the merger, each share of PrivateBancorp common stock, without par value, will be converted into the right to receive without interest (i) 0.3657 common shares of CIBC and (ii) $18.80 in cash (the consideration described in clauses (i) and (ii), collectively, the "merger consideration"). The value of the merger consideration constituting common shares of CIBC described in clause (i) will depend on the market price of CIBC common shares at the time you receive the CIBC common shares (following completion of the merger). For a discussion of the treatment of awards outstanding under PrivateBancorp's equity incentive plans as of the effective time, see "The Merger Agreement—Treatment of PrivateBancorp Equity Awards" beginning on page 106 of this proxy statement/prospectus.

CIBC will not issue any fractional CIBC common shares in the merger. Instead, a PrivateBancorp common stockholder who otherwise would have received a fraction of a CIBC common share will receive an amount in cash, rounded to the nearest cent, determined by multiplying (i) the volume-weighted average trading price of one CIBC common share for the 10 day-period in which both the Canadian and U.S. markets are open for trading ending on the last such day immediately preceding the closing date of the merger, calculated using both Canadian and U.S. trading prices and volumes during normal market hours and assuming, in respect of such trading prices on the TSX for each trading day, the Bank of Canada daily noon Canada/U.S. exchange rate for the Canadian calculations (the "CIBC share closing price") by (ii) the fraction of a CIBC common share (rounded to the nearest thousandth when expressed in decimal form) to which such holder would otherwise be entitled (after taking into account all shares of PrivateBancorp common stock owned by such holder as of immediately prior to the effective time). Accordingly, the value of the cash consideration that you will receive in lieu of any fractional CIBC common shares will depend on the CIBC share closing price.

Conversion of PrivateBancorp Common Stock; Exchange of Certificates

The conversion of PrivateBancorp common stock into the right to receive the merger consideration will occur automatically upon completion of the merger (except, with respect to dissenting shares as discussed below). As soon as reasonably practicable after completion of the merger, an exchange agent will exchange certificates or book entry shares representing shares of PrivateBancorp common stock for merger consideration to be received by holders of PrivateBancorp common stock in the merger pursuant to the terms of the merger agreement.

Table of Contents

Letter of Transmittal

Soon after the completion of the merger, the exchange agent will send a letter of transmittal to only those persons who were PrivateBancorp common stockholders at the effective time of the merger. This mailing will contain instructions on how to surrender shares of PrivateBancorp common stock (if these shares have not already been surrendered) in exchange for the merger consideration that the holder is entitled to receive under the merger agreement. If a certificate for PrivateBancorp common stock has been lost, stolen or destroyed, the exchange agent will issue the consideration properly payable under the merger agreement upon receipt of appropriate evidence as to that loss, theft or destruction, appropriate evidence as to the ownership of that certificate by the claimant, and appropriate and customary indemnification.

Withholding

CIBC is entitled to deduct and withhold, or cause the surviving entity (i.e., Holdco) or the exchange agent to deduct and withhold, from the cash portion of the aggregate merger consideration, any cash in lieu of fractional CIBC common shares, and cash dividends or distributions payable to any holder of PrivateBancorp common stock such amounts as it is required to deduct and withhold under any federal, state, local or foreign tax law. If any such amounts are withheld, these amounts will be treated for all purposes of the merger as having been paid to the PrivateBancorp common stockholders from whom they were withheld.

Dividends and Distributions

Until PrivateBancorp common stock certificates or book-entry shares are surrendered for exchange, any dividends or other distributions having a record date after the effective time of the merger with respect to the CIBC common shares into which shares of PrivateBancorp common stock have been converted will accrue but will not be paid. CIBC will pay to former PrivateBancorp common stockholders any unpaid dividends or other distributions, without interest, only after they have duly surrendered their PrivateBancorp common stock certificates or book-entry shares. After the effective time of the merger, there will be no transfers on the stock transfer books of PrivateBancorp of any shares of PrivateBancorp common stock. If certificates representing shares of PrivateBancorp common stock are presented for transfer after the completion of the merger, they will be cancelled and exchanged for the merger consideration into which the shares of PrivateBancorp common stock represented by that certificate have been converted.

Dissenting Shares

Shares held by PrivateBancorp common stockholders who have perfected and not lost their right to dissenters' rights of appraisal in accordance with the procedures and requirements of Delaware law will not be converted into the right to receive the merger consideration, and such PrivateBancorp common stockholders will be entitled only to the rights granted by Delaware law. If any such PrivateBancorp stockholder withdraws or loses his, her or its right to dissent under Delaware law at or prior to the effective time of the merger, the shares of PrivateBancorp common stock held by such PrivateBancorp stockholder will be converted into the right to receive the merger consideration.

Background of the Merger

The board of directors of PrivateBancorp has regularly reviewed and discussed PrivateBancorp's business, performance, prospects and long-term strategy in the context of developments in the banking industry, the competitive landscape, PrivateBank's predominantly middle market commercial banking business model and its expected growth trajectory under the leadership of the current executive management team. The board's strategic discussions have focused on the company's balance sheet risk profile resulting from loan and deposit concentrations inherent in its commercial banking model and its core deposit gathering potential given a limited retail branch network. Among other things, the board

Table of Contents

has considered the ability of PrivateBank's funding strategy to continue supporting its organic loan growth over the long term, the potential business impact of uncertainty about future interest rate changes and the infrastructure investments and additional personnel capabilities that may be required to successfully manage a larger banking organization in the current regulatory environment. In light of the foregoing, the board has considered, from time to time, various potential strategic alternatives to diversify its funding base, including acquisitions or business combinations involving other financial institutions, such as possible acquisitions of bank holding companies of a smaller size operating primarily in the Chicago area or business combinations with larger banking institutions in the midwest region. PrivateBancorp also considered standalone alternatives such as increasing its number of traditional bank branches and developing a more robust online banking platform. In considering the feasibility of these various alternatives, the board considered, among other factors, the inherent risks and uncertainties associated with pursuing an acquisition strategy or seeking to significantly grow PrivateBank's core deposit gathering platform through organic growth strategies.

CIBC periodically evaluates potential acquisitions of financial institutions, particularly in North America. In early 2014, CIBC announced the completion of its acquisition of Atlantic Trust Private Wealth Management, a leading U.S.-based private wealth management firm, from Invesco Ltd. Following that announcement, on several occasions, CIBC publicly expressed its interest in further expanding its banking and wealth management capabilities in the United States, as part of its overall strategy of creating a financially strong, innovative and client-focused bank and as a means of diversifying CIBC's earnings and funding.

Mr. Victor Dodig, Chief Executive Officer of CIBC, and Mr. Richman, Chief Executive Officer of PrivateBancorp, had met informally a few times over the past number of years and discussed generally their respective businesses, the general nature and needs of their respective clients, the current state of the banking industry and the opportunities and challenges faced by banks in the current environment. During the middle of 2015, Mr. Dodig and Mr. Michael Capatides, Senior Executive Vice-President, Chief Administrative Officer and General Counsel of CIBC, met with Mr. Richman in Chicago to more specifically discuss their respective organizations' corporate cultures, shared focus on client relationships and the potential for a possible combination between the two companies generally. Mr. Richman also subsequently visited with Mr. Dodig, Mr. Capatides and other members of CIBC's executive management team in Toronto for the parties to further learn about the other's business and culture, and had other informal conversations with Mr. Dodig. Those meetings and conversations did not, at that time, include any discussion of specific transaction terms. During that time, Mr. Richman provided frequent updates to the PrivateBancorp board of directors about the general nature of his preliminary discussions with Mr. Dodig and about CIBC generally.

In early November 2015, Mr. Dodig and Mr. Capatides met with Mr. Richman and PrivateBancorp's Chief Financial Officer and General Counsel in Chicago to more specifically discuss the possibility of the parties exploring a potential business combination. They also discussed the possibility of entering into a non-exclusive mutual confidentiality agreement so that the parties could continue their preliminary non-binding discussions of the potential benefits and risks of a business combination. At a regularly scheduled meeting of the PrivateBancorp board of directors held later that week, Mr. Richman updated the board on management's meeting with Messrs. Dodig and Capatides and informed the directors of the parties' intent to enter into a non-exclusive mutual confidentiality agreement. At that meeting, PrivateBancorp's General Counsel reviewed for the board of directors the nature of the directors' fiduciary duties in connection with the consideration of various strategic alternatives, including an acquisition of or by PrivateBancorp or a business combination involving PrivateBancorp. Following these presentations and after discussion, the board supported Mr. Richman continuing to engage in exploratory discussions with Mr. Dodig, but also directed management to continue evaluating other alternatives consistent with the board's prior strategic discussions. Additionally, the board directed management to request that representatives of Goldman, Sachs & Co., financial advisor to PrivateBancorp, which we refer to as Goldman Sachs, attend the board's next

Table of Contents

regularly scheduled meeting in December 2015. Shortly following the November 2015 board meeting, the parties executed a non-exclusive mutual confidentiality agreement.

At its December 2015 meeting, the board reviewed PrivateBancorp's 2016 profit plan and engaged in a discussion with management regarding various assumptions underlying such plan, including funding considerations. The board continued its discussions of potential strategic options for PrivateBancorp, with a particular focus on the funding strategy to support its continued organic loan growth. During this meeting, representatives of Goldman Sachs reviewed with the board the current operating environment and outlook for U.S. regional banks, issues impacting the banking industry generally and leading economic indicators. Goldman Sachs also discussed the current market for mergers and acquisitions of financial institutions in the United States and in the Chicago region (including those comparable to PrivateBancorp), as well as strategic and financial considerations for PrivateBancorp. As part of this discussion, Goldman Sachs provided an overview of potential acquisition targets and merger partners. Additionally, Goldman reviewed several acquirors who could potentially have the ability to acquire an organization the size of PrivateBancorp, as well as circumstances specific to each that may impact their ability or willingness to pursue a large transaction at that time. The board reviewed and engaged in extensive discussions with management and representatives of Goldman Sachs regarding various strategic alternatives.

Following the December 2015 meeting, it was the opinion of the board, based on its discussions at this meeting and over prior months about the company's strategic objectives and business outlook, that continuing discussions with CIBC would be in the best interests of PrivateBancorp and its stockholders. As a result, the board authorized Mr. Richman to continue these discussions.

On January 19, 2016, Mr. Dodig contacted Mr. Richman to make an initial, oral and non-binding transaction proposal with an implied value of $44.00 per share, with the consideration to consist of 60% CIBC common shares and 40% cash. Mr. Richman advised Mr. Dodig that he would discuss CIBC's proposal with PrivateBancorp's board of directors at its next regularly scheduled meeting.

Later that month, the PrivateBancorp board of directors discussed the transaction proposal received from CIBC on January 19, 2016. Representatives of Goldman Sachs attended the meeting and provided an overview of the financial terms of CIBC's proposal. The board decided that more focused conversations with CIBC may ultimately be warranted but that further discussion of CIBC's offer and a proposed improvement in its terms would likely be required to merit further consideration and periodic engagement with CIBC in the near term. To assist the board during the early stages of discussions in evaluating the terms of any potential transaction with CIBC, the board formed a special strategic opportunities committee comprised of James M. Guyette, William R. Rybak and Michelle L. Collins, each a PrivateBancorp independent director, which we refer to as the special committee. In addition, in connection with its regular annual review of strategic plans for long-term value creation, the board reviewed and discussed, among other things, PrivateBancorp's long-term growth plan, the impact of PrivateBank's commercial banking-focused business model on that growth plan and strategic options for diversifying its overall funding base, including by enhancing core deposit gathering capabilities, to support continued organic loan growth and the potential risks and uncertainties of pursuing certain strategic options, such as acquisitions of other banking organizations to diversify its deposit base. The board also discussed PrivateBancorp's strategic, business and operational capabilities that would be critical to future growth plans.

The special committee met on a periodic basis over the next several weeks to continue discussions regarding CIBC's initial non-binding $44.00 per share transaction proposal and the board's strategic objectives and opportunities and reported to the PrivateBancorp board on these discussions. After considering the financial analyses discussed with Goldman Sachs and input from management, the special committee and the PrivateBancorp board determined that the proposal did not reflect adequate value for PrivateBancorp's stockholders, which determination was subsequently communicated to CIBC.

Table of Contents

On February 17, 2016, a small number of executives of CIBC and PrivateBancorp met in person in Chicago to discuss their respective organizations, the possibility of engaging in further dialogue regarding a potential business combination and the determination of PrivateBancorp's board of directors that CIBC's $44.00 per share proposal did not reflect adequate value for PrivateBancorp's stockholders. During the meeting, PrivateBancorp's representatives also responded to certain initial high-level due diligence questions from CIBC that did not involve disclosure of any non-public information of PrivateBancorp. Following that meeting, Mr. Dodig communicated to Mr. Richman that CIBC would be prepared to increase its non-binding transaction proposal to $44.50 per share of PrivateBancorp common stock, with the same mix of 60% CIBC common shares and 40% cash. The special committee and the PrivateBancorp board each met later that month to discuss the revised CIBC proposal, which meetings were attended by representatives of Goldman Sachs. After discussion among the special committee and the board with PrivateBancorp's management and advisors, including an overview of the financial terms of the proposal provided by representatives of Goldman Sachs, CIBC's recent financial performance and financial considerations for PrivateBancorp, it was the opinion of the special committee and the board that the revised offer of $44.50 per share still did not reflect adequate value for PrivateBancorp's stockholders and, accordingly, that CIBC should not be granted access to commence a more fulsome due diligence investigation without an increased offer. This view was subsequently communicated by Mr. Richman to Mr. Dodig. During this conversation, Mr. Richman and Mr. Dodig agreed that their respective financial advisors should engage in direct discussions to understand each party's financial perspective and to support CIBC's ongoing high-level due diligence review of publicly available information of PrivateBancorp.

On March 29, 2016, CIBC submitted a revised non-binding written proposal, which valued PrivateBancorp common stock at $47.00 per share, consisting of 60% in CIBC common shares and 40% in cash, with a fixed exchange ratio to be agreed between the parties prior to the execution of any definitive agreement. CIBC's March 29 proposal indicated that CIBC would expect PrivateBancorp's management team to continue operating the PrivateBancorp business following the merger, with Mr. Richman becoming a member of CIBC's global Executive Committee and overseeing CIBC's banking and wealth management franchises in the U.S. The proposal contemplated that Mr. Richman would enter into an employment agreement providing for his continued service as President and CEO of PrivateBancorp for three years and as Chairman of PrivateBancorp for an additional two years. The proposal was subject to CIBC's completion of a more fulsome due diligence investigation of PrivateBancorp, which CIBC indicated that it would like to begin promptly, as well as CIBC obtaining final approval from its board of directors and the parties' negotiation of a mutually acceptable definitive agreement. The proposal also indicated the regulatory approvals that CIBC expected to be required in connection with the merger.

Shortly following receipt of CIBC's March 29 proposal, the special committee and the PrivateBancorp board each met again, including with representatives of Goldman Sachs and of Wachtell, Lipton, Rosen & Katz, PrivateBancorp's legal counsel, which we refer to as Wachtell Lipton, to consider the revised offer and the merits of providing access to PrivateBancorp's non-public material information to facilitate CIBC's desire to complete its due diligence investigation. CIBC's March 29 proposal was considered in the context of the board's previous extensive strategic discussions regarding PrivateBancorp's long-term growth plans, options for expanding its core deposit gathering capabilities and diversifying its overall funding base, the potential risks and opportunities presented by these options and the potential likelihood of and time horizon for successfully implementing these strategies. The board discussed the potential benefits of PrivateBank becoming part of a significantly larger banking organization with a strong credit rating and the opportunity for the U.S. banking business, with an enhanced funding strategy, to contribute to CIBC's overall financial performance. Representatives of Goldman Sachs also reviewed with the board the financial terms of selected U.S. bank and thrift merger transactions involving targets with greater than $5 billion in assets. The PrivateBancorp board discussed other potential acquirors that were identified and discussed by Goldman Sachs at a prior

Table of Contents

board meeting, including specific circumstances of these other potential acquirors that may impact their ability or appetite to pursue a large transaction, the analysis of Goldman Sachs regarding the financial ability of CIBC to complete a large transaction, and the potential benefits and risks of affirmatively soliciting acquisition proposals from parties other than CIBC (including, among other things, the risk of potential disruption to the business from a sale process involving additional third parties should information about the process leak into the public markets). Following this discussion, the board determined, taking into account the information obtained from its financial advisor, that there were likely to be limited or no potential purchasers with the ability and willingness to acquire a financial institution of PrivateBancorp's type and size in the current regulatory environment. In addition, the board concluded, taking into account the information obtained from its financial advisor and taking into account advice from management, that the risks associated with attempting to affirmatively solicit other business combination proposals outweighed the potential benefits of soliciting other proposals. After extensive discussion of the financial terms of the revised proposal, such risks and potential benefits, and an updated overview by Goldman Sachs of the financial terms of the revised proposal and financial considerations for PrivateBancorp, it was the consensus of the board that PrivateBancorp should allow CIBC to commence the requested due diligence investigation and, because CIBC was proposing to use its stock for 60% of the consideration in its transaction proposal, PrivateBancorp should initiate a "reverse" due diligence investigation of CIBC.

In mid-April 2016, CIBC was granted access to a virtual data room populated by PrivateBancorp and its advisers for the purpose of commencing more fulsome documentary due diligence review of PrivateBancorp. Around that time, representatives of CIBC contacted representatives of PrivateBancorp to request that the confidentiality agreement entered into in November 2015 be amended, in recognition of the considerable resources expected to be committed by the parties in completing their respective due diligence processes, to include customary exclusivity and standstill provisions. On April 25, 2016, and based upon the determination by the PrivateBancorp board at its prior meeting that the risks associated with attempting to affirmatively solicit business combination proposals from other potential parties outweighed the potential benefits of possibly having competing offers to consider, and in order to facilitate CIBC continuing its due diligence process, the parties entered into an amended confidentiality agreement, which included a 30-day exclusivity period requested by CIBC and a customary standstill provision applicable to CIBC. Later that month, representatives of CIBC met in Chicago with a team of PrivateBancorp representatives to discuss initial diligence matters.

CIBC's due diligence investigation of PrivateBancorp continued over the next several weeks, with PrivateBancorp providing detailed non-public information and making select executives and other employees available to CIBC to facilitate its evaluation. To protect PrivateBancorp from the risk that the parties might be unable to reach agreement on the definitive terms of a transaction, and to avoid potential disruptions to the on-going business operations, PrivateBancorp required CIBC to complete its due diligence in distinct phases, focusing initially on PrivateBank's loan portfolio, credit risk, certain treasury matters and PrivateBancorp's three-year business plan, and without providing CIBC with direct access to, or involving, any PrivateBancorp executives or employees who were not specifically approved in advance by Mr. Richman. In addition, during this period, PrivateBancorp and its advisors began to engage in discussions with CIBC regarding the proposed terms of Mr. Richman's employment by CIBC following a transaction, in order to address CIBC's expectation that Mr. Richman become an executive of CIBC responsible for the combined U.S. banking and wealth management franchise, as outlined in CIBC's March 29 proposal. In late May, the PrivateBancorp board of directors met to discuss the status of CIBC's due diligence and the discussions regarding a potential transaction. At this meeting, the board decided that in light of the additional due diligence performed by CIBC since CIBC's March 29 proposal, it would direct PrivateBancorp's management and advisors to request that, before proceeding with expanded management due diligence, CIBC provide the terms on which it was willing to move forward with negotiating a definitive agreement.

Table of Contents

On May 31, 2016, at PrivateBancorp's request, CIBC wrote PrivateBancorp to re-confirm its interest in pursuing a business combination and provided additional details concerning its transaction proposal. CIBC's May 31 letter stated CIBC was prepared to acquire PrivateBancorp for $18.80 in cash and 0.3786 CIBC common shares per share of PrivateBancorp common stock, representing the exchange ratio as though it was set based on the closing share prices of PrivateBancorp and CIBC of March 29, 2016 when the $47.00 price was indicated in CIBC's prior proposal and PrivateBancorp allowed CIBC to commence its requested due diligence process on that basis. The letter also specified that the proposal remained subject to CIBC's completion of its remaining due diligence, obtaining approval from its board of directors and the parties' execution of mutually acceptable definitive agreements, included, among other things, information regarding the proposed treatment of PrivateBancorp equity awards in the merger and reiterated CIBC's expectation that Mr. Richman would continue in a role at PrivateBancorp and enter into an employment agreement on the terms previously indicated. CIBC also indicated that it would expect to complete its remaining due diligence within two weeks of receiving information that it had requested.

On June 8, 2016, as part of CIBC's ongoing due diligence review of PrivateBancorp, representatives of CIBC's senior management team met in person in Chicago with PrivateBancorp's management and business line heads to discuss PrivateBancorp's business operations and financial outlook. CIBC's detailed due diligence investigation continued during the month of June until the announcement of the transaction. Also in the first half of June, PrivateBancorp conducted reverse due diligence of public and non-public information regarding CIBC, including an in-person meeting in Toronto on June 13, 2016 to discuss CIBC's business operations and financial and regulatory outlook among members of senior management of CIBC and PrivateBancorp that was attended by their respective financial advisors and representatives of Wachtell Lipton. Among other topics, the PrivateBancorp team focused on CIBC's oil-and-gas-related exposure given its concentration in the Canadian market, its contemplated U.S. expansion strategy and the role of the PrivateBancorp organization and leadership in that strategy. PrivateBancorp's evaluation of CIBC continued until shortly prior to the parties' announcement that they had entered into the merger agreement.

Shortly following these reverse due diligence meetings, Mayer Brown LLP, CIBC's legal counsel, provided Wachtell Lipton a draft merger agreement and the parties began to negotiate transaction documentation simultaneously with the ongoing due diligence investigations. Additionally, on June 21, the PrivateBancorp board engaged Sandler O'Neill & Partners, L.P., which we refer to as Sandler, to review the financial terms of the proposed transaction and to prepare and render to the PrivateBancorp board, in connection with its consideration of the proposed merger, an opinion as to whether the proposed merger consideration was fair, from a financial point of view, to the holders of PrivateBancorp common stock. PrivateBancorp engaged Sandler because Sandler is a nationally recognized investment banking firm whose principal business specialty is financial institutions and that has significant recent experience advising on financial institutions transactions. The engagement of Sandler was not due to any potential or perceived conflict of interest on the part of Goldman Sachs.

On June 23, 2016, Mayer Brown LLP provided Wachtell Lipton a draft employment agreement between CIBC and Mr. Richman providing for the terms of Mr. Richman's employment by CIBC following the completion of a transaction, consistent with the condition to CIBC's offer as outlined in the March 29 proposal. The parties and their respective advisors discussed and negotiated the terms of the draft agreement from this date until June 29, the date that the merger agreement was entered into and the transaction was announced.

On June 24, 2016, Mr. Dodig and Mr. Richman discussed the current status of discussions between the parties and recent volatility in the financial markets. Following that discussion, PrivateBancorp requested CIBC to confirm the terms of its transaction proposal in advance of a meeting of the PrivateBancorp board scheduled to be held on June 27. On the evening of June 26, CIBC sent a letter to PrivateBancorp confirming that it was prepared to enter into a merger agreement with PrivateBancorp for an implied merger consideration value of $47.00 per share of PrivateBancorp

Table of Contents

common stock, consisting of $18.80 in cash (representing 40% of the total merger consideration) and a fixed number of CIBC common shares to be reflected in an exchange ratio calculated as $28.20 (representing 60% of the total merger consideration) divided by the latest closing price on the NYSE of CIBC common shares immediately prior to public announcement of the transaction. The letter also stated that CIBC's proposal was subject to no material further deterioration in financial markets, obtaining final approval from the CIBC board of directors and the execution of mutually acceptable definitive agreements.

On June 27, 2016, the PrivateBancorp board held a special meeting, attended by PrivateBancorp management, representatives of Goldman Sachs and Sandler, and representatives of Wachtell Lipton. Mr. Richman began the meeting with an update regarding the status of the potential transaction and a discussion of the current offer as communicated in the letter received from CIBC the previous evening. At the meeting, representatives of PrivateBancorp's management and Goldman Sachs and Sandler discussed with the board the potential opportunity with CIBC, recent financial market and economic events and the banking landscape, CIBC's businesses, performance, competitive positioning and valuation metrics (including views of analysts and rating agencies), the results of the reverse due diligence review of CIBC performed by PrivateBancorp management and the company's financial and legal advisors, and valuation metrics for PrivateBancorp. Representatives of PrivateBancorp management and Goldman Sachs and Sandler noted that the proposal made by CIBC the previous evening of $47.00 per share of PrivateBancorp common stock represented approximately a 25.9% premium to the closing price of PrivateBancorp common stock on the NASDAQ the previous trading day. The board discussed with PrivateBancorp's management and financial advisors the implied value of CIBC's offer relative to PrivateBancorp's current valuation and long-term outlook in light of recent market developments and economic events.

After further discussion among members of the board, representatives of Goldman Sachs and Sandler then separately (without the other present) reviewed with the board their financial analysis of the merger consideration, as more fully described below under the heading "—Opinions of PrivateBancorp's Financial Advisors." Following this discussion, representatives of Wachtell Lipton circulated a summary of the current draft of the merger agreement to each member of the board. Wachtell Lipton reviewed for the board of directors the fiduciary duties of the directors in connection with their consideration of the transaction, as had previously been discussed with the board, and the terms of the proposed merger agreement with CIBC. The representatives of Wachtell Lipton also reviewed with the directors the proposed post-merger employment arrangements with Mr. Richman, the proposed post-merger governance commitments by CIBC and the treatment of outstanding PrivateBancorp equity awards and other compensation- and benefits-related matters for PrivateBancorp employees.

At this point in the meeting, at the request of PrivateBancorp, Mr. Dodig and Mr. Capatides of CIBC joined the PrivateBancorp board meeting in a session in which representatives of PrivateBancorp's advisors were not present. Mr. Dodig discussed CIBC's strategic approach and goals for the combined company if a transaction were to occur, and responded to questions from the PrivateBancorp board regarding the proposed transaction and market developments. Mr. Dodig also noted that CIBC's board of directors was scheduled to meet the following day to consider the proposed transaction for approval. At the conclusion of the June 27 meeting, based on management's presentation, the financial analysis provided by Goldman Sachs and Sandler, the review of terms of the proposed merger agreement and the discussion with Mr. Dodig and Mr. Capatides, PrivateBancorp's board reached consensus that it was prepared to approve entering into a merger agreement with CIBC on the terms proposed by CIBC in its June 26 letter, and requested Mr. Richman to inform Mr. Dodig prior to CIBC's board meeting the following day of the PrivateBancorp board's commitment to those terms. Mr. Richman communicated the PrivateBancorp board's decision to Mr. Dodig, and Mr. Dodig stated that he would inform Mr. Richman whether the proposal had been approved by the CIBC board at its upcoming meeting.

Table of Contents

During the afternoon of June 28, 2016, following the meeting of the CIBC board of directors held earlier that day, Mr. Dodig telephoned Mr. Richman to confirm that the CIBC board had approved entering into a merger agreement with PrivateBancorp at a price of $47.00 per share, for consideration consisting of $18.80 in cash and $28.20 in CIBC common shares, at a fixed exchange ratio based on the closing price of CIBC common shares that day.

During the evening of June 28, 2016, the PrivateBancorp board of directors convened a special meeting. Mr. Richman described to the board his conversation with Mr. Dodig earlier in the day, including that the CIBC board of directors had approved entering into a definitive merger agreement with PrivateBancorp for merger consideration consisting of $18.80 in cash and 0.3657 CIBC common shares, implying a total value of the merger consideration of $47.00 per share of PrivateBancorp common stock based on the closing price of CIBC common shares that day.

Following this discussion, representatives of Goldman Sachs and Sandler then reviewed with the board their financial analysis of the merger consideration that was discussed with the board at the meeting the previous day, as more fully described below under the heading "—Opinions of PrivateBancorp's Financial Advisors," and each of the firms rendered to the PrivateBancorp board of directors its respective oral opinion (subsequently confirmed in writing) that, as of that date and based on and subject to various assumptions, matters considered and limitations described in the opinion, the merger consideration to be paid to the holders of shares of PrivateBancorp common stock pursuant to the merger agreement was fair, from a financial point of view, to those holders. After discussion, and in light of the board's review and consideration of the factors described under "—PrivateBancorp's Reasons for the Merger; Recommendation of the PrivateBancorp Board of Directors", as well as the other types of strategic alternatives that had been considered by the board, as described in the first paragraph of this section entitled "—Background of the Merger", and the terms of the transaction with PrivateBancorp relative to the potential benefits, risks and uncertainties involved with potentially pursuing other alternatives, the board unanimously determined that the merger and the other transactions contemplated by the merger agreement were advisable and in the best interests of PrivateBancorp and its stockholders, and the board unanimously approved and adopted the merger and determined to recommend that PrivateBancorp common stockholders approve and adopt the merger agreement.

During the morning of June 29, 2016, the parties entered into the merger agreement and publicly announced the merger the same day.

PrivateBancorp's Reasons for the Merger; Board Recommendation of the PrivateBancorp Board of Directors

After careful consideration, and in consultation with PrivateBancorp's management and external financial and legal advisors, the PrivateBancorp board unanimously determined that the merger agreement, the merger and the other transactions contemplated by the merger agreement were advisable, fair to and in the best interests of PrivateBancorp and its stockholders and approved and adopted the merger agreement, the merger and the other transactions contemplated by the merger agreement. Accordingly, the PrivateBancorp board unanimously recommends that its common stockholders approve and adopt the merger agreement, the merger and the other transactions contemplated by the merger agreement.

The PrivateBancorp board considered a number of factors in determining to approve the merger agreement, the merger and the other transactions contemplated by the merger agreement, including the following material factors:

•: the implied value of the merger consideration of $47.00 as of June 28, 2016 (the day of the board meeting at which the board approved the transaction) represented a premium of approximately 31% to the closing price of PrivateBancorp common stock on the NASDAQ as of

Table of Contents

June 28, 2016 and was 2.2 times PrivateBancorp's tangible book value per share as of March 31, 2016;

•: the cash component of the transaction offers PrivateBancorp common stockholders the opportunity to realize cash for the value of their shares with immediate certainty of value and mitigates some of the risk of the value of the merger consideration decreasing prior to closing as a result of a decline in the trading price of CIBC common shares;
•: the stock component of the transaction offers PrivateBancorp common stockholders the opportunity to participate in the future growth and opportunities of the combined company, and the expected tax treatment of the merger as a "reorganization" for U.S. federal income tax purposes, such that receipt of share consideration (other than any cash in lieu of fractional shares) will generally be tax-free to PrivateBancorp's common stockholders, as further described under "The Merger—Material United States Federal Income Tax Consequences";

•: the potential for PrivateBancorp's common stockholders, as future CIBC shareholders, to benefit to the extent of their interest in the combined company from the synergies of the merger, in particular, enhanced revenue opportunities, and the anticipated pro forma impact of the merger discussed with the PrivateBancorp board, and the expectation that the merger will be accretive to CIBC's adjusted earnings per share in year three;
•: the view that the shared core values of PrivateBancorp and CIBC, including both companies' prudent risk culture, strong commitment to client service and focus on building solid client relationships, would assist in integration and operating the combined company post-closing and the combined strength of CIBC's and PrivateBancorp's management teams would benefit PrivateBancorp common stockholders as future CIBC shareholders;

In considering the recommendation of the PrivateBancorp board, you should be aware that certain directors and officers of PrivateBancorp may have interests in the merger that are different from, or in addition to, interests of stockholders of PrivateBancorp generally and may create potential conflicts of interest. The PrivateBancorp board was aware of these interests and considered them when evaluating

and negotiating the merger agreement, the merger and the other transactions contemplated by the merger agreement, and in recommending to PrivateBancorp's common stockholders that they vote in favor of the merger agreement proposal. See "The Merger—Interests of PrivateBancorp Directors and Executive Officers in the Merger."

This discussion of the information and factors considered by the PrivateBancorp board includes the material factors considered by the PrivateBancorp board, but it is not intended to be exhaustive and may not include all the factors considered by the PrivateBancorp board. In view of the wide variety of factors considered, and the complexity of these matters, the PrivateBancorp board did not quantify or assign any relative or specific weights to the various factors that it considered in reaching its determination to adopt and approve the merger agreement, the merger and the other transactions contemplated by the merger agreement. Rather, the PrivateBancorp board viewed its recommendation as being based on the totality of the information presented to and factors considered by it, including discussions with, and questioning of, PrivateBancorp's management and its financial and legal advisors. In addition, individual members of the PrivateBancorp board may have given differing weights to different factors. It should be noted that this explanation of the reasoning of the PrivateBancorp board and certain information presented in this section is forward-looking in nature and, therefore, that information should be read in light of the factors discussed in the section entitled "Cautionary Statement Regarding Forward-Looking Statements."

For the reasons set forth above, the PrivateBancorp board of directors unanimously recommends that the PrivateBancorp common stockholders vote "FOR" the merger agreement proposal.

The full text of the written opinion of Goldman Sachs, dated June 29, 2016, which sets forth assumptions made, procedures followed, matters considered, qualifications and limitations on the review undertaken in connection with the opinion, is attached to this proxy statement/prospectus as Appendix B. The summary of the Goldman Sachs opinion contained in this proxy statement/prospectus is qualified in its entirety by reference to the full text of Goldman Sachs' written opinion. Goldman Sachs' advisory services and opinion were provided for the information and assistance of the board of directors of PrivateBancorp in connection with its consideration of the merger and the opinion does not constitute a recommendation as to how any holder of PrivateBancorp common stock should vote with respect to the proposed transaction or any other matter.

In connection with rendering the opinion described above and performing its related financial analyses, Goldman Sachs reviewed, among other things:

•: the merger agreement;
•: annual reports to stockholders and Annual Reports on Form 10-K of PrivateBancorp for the five fiscal years ended December 31, 2015 and annual reports to shareholders and Annual Reports on Form 40-F of CIBC for the five fiscal years ended October 31, 2015;

Goldman Sachs also held discussions with members of the senior management of PrivateBancorp regarding their assessment of the past and current business operations, financial condition and future prospects of PrivateBancorp and CIBC and the strategic rationale for, and the potential benefits of, the proposed transaction; and with members of the senior management of CIBC regarding their assessment of the past and current business operations, financial condition and future prospects of CIBC and the strategic rationale for, and the potential benefits of, the proposed transaction; reviewed the reported price and trading activity for PrivateBancorp common stock and CIBC common shares; compared certain financial and stock market information for PrivateBancorp and CIBC with similar information for certain other companies the securities of which are publicly traded; reviewed the financial terms of certain recent business combinations in the banking industry; and performed such other studies and analyses, and considered such other factors, as Goldman Sachs deemed appropriate.

For purposes of rendering its opinion, Goldman Sachs, with the consent of the PrivateBancorp board of directors, relied upon and assumed the accuracy and completeness of all of the financial, legal, regulatory, tax, accounting and other information provided to, discussed with or reviewed by, Goldman Sachs, without assuming any responsibility for independent verification thereof. In that regard, Goldman Sachs assumed with the consent of the board of directors of PrivateBancorp that the Forecasts, including the Synergies, have been reasonably prepared and reflect the best currently available estimates and judgments of the management of PrivateBancorp. Goldman Sachs did not review individual credit files or make an independent evaluation or appraisal of the assets and liabilities (including any contingent, derivative or other off-balance-sheet assets and liabilities) of PrivateBancorp or CIBC or any of their respective subsidiaries and Goldman Sachs was not furnished with any such evaluation or appraisal. Goldman Sachs is not an expert in the evaluation of loan and lease portfolios for purposes of assessing the adequacy of the allowances and marks for losses with respect thereto, and, accordingly, Goldman Sachs assumed that such allowances and marks are in the aggregate adequate to cover such losses. Goldman Sachs assumed that all governmental, regulatory or other consents and approvals necessary for the consummation of the proposed transaction will be obtained without any adverse effect on PrivateBancorp or CIBC or on the expected benefits of the proposed transaction in any way meaningful to Goldman Sachs' analysis. Goldman Sachs assumed that the proposed transaction will be completed on the terms set forth in the merger agreement, without the waiver or modification of any term or condition the effect of which would be in any way meaningful to its analysis.

Illustrative Present Value of Future Stock Price Analyses for PrivateBancorp on a Stand-alone Basis

Goldman Sachs performed an illustrative analysis of the implied present value of the future value per share of the common stock of PrivateBancorp on a stand-alone basis.

Goldman Sachs first derived a range of theoretical future values per share for PrivateBancorp common stock as of December 31, 2016, 2017 and 2018, by applying illustrative price to EPS multiples ranging from 14.0x to 16.0x to the estimates of PrivateBancorp's EPS for the years ending December 31, 2017, 2018 and 2019, respectively, reflected in the PrivateBancorp Financial Forecasts. By applying a discount rate of 12%, reflecting an estimate of PrivateBancorp's cost of equity on a stand-alone basis, Goldman Sachs discounted to present value as of March 31, 2016, both the theoretical future values per share it derived and the estimated dividends to be paid per share of PrivateBancorp common stock through the end of the applicable year as reflected in the PrivateBancorp Financial Forecasts to yield illustrative present values per share of common stock of PrivateBancorp on a stand-alone basis ranging from $30.01 to $37.36.

Illustrative Discounted Dividend Analyses for PrivateBancorp on a Stand-Alone Basis

Using PrivateBancorp Financial Forecasts, Goldman Sachs performed an illustrative discounted dividend analyses on PrivateBancorp, on a stand-alone basis, to derive a range of illustrative present values per share of PrivateBancorp common stock on a stand-alone basis.

Using discount rates ranging from 11.0% to 13.0%, reflecting estimates of the cost of equity for PrivateBancorp on a stand-alone basis, derived by application of the Capital Asset Pricing Model, which incorporates certain company-specific inputs, including a beta for the company, as well as certain financial metrics for the United States markets generally, Goldman Sachs derived a range of illustrative equity values for PrivateBancorp on a stand-alone basis by discounting to present value as of March 31, 2016, (a) the estimated dividends to be paid by PrivateBancorp to PrivateBancorp's stockholders and the estimated cash infusion to be made into PrivateBancorp over the period beginning March 31, 2016 through the year ending December 31, 2021, based on the PrivateBancorp Financial Forecasts and PrivateBancorp maintaining a common equity tier 1 ratio, or "CET1 Ratio," ranging from 9.0% to 10.0%, and (b) a range of illustrative terminal values for PrivateBancorp on a stand-alone basis as of December 31, 2021, calculated by applying illustrative price to EPS multiples ranging from 14.0x to 16.0x to the estimate of PrivateBancorp's EPS for the year ending December 31, 2022, reflected in the PrivateBancorp Financial Forecasts. Goldman Sachs then divided the range of illustrative equity values it derived for PrivateBancorp by the total number of fully diluted shares of PrivateBancorp common stock outstanding as provided by PrivateBancorp management to derive illustrative present values per share of common stock of PrivateBancorp on a stand-alone basis ranging from $31.35 to $38.82.

Company Stand-Alone Regression Analysis

Goldman Sachs performed a regression analysis using the price/TBV per share multiples for the selected companies calculated by Goldman Sachs as summarized under "—Selected Companies Analyses for PrivateBancorp on a Stand-alone Basis" above compared to the estimated 2016 return on average tangible common equity, or the "2016E ROATCE," for the selected companies using the median estimates for such companies published by IBES as of June 24, 2016, to derive a regression line reflecting a range of Price/TBV per share multiples at a range of 2016E ROATCEs for the selected companies. The 2016E ROATCE for PrivateBancorp on a stand-alone basis, as reflected in the PrivateBancorp Financial Forecasts corresponded to a Price/TBV per share multiple of 1.8x on the regression line. By applying Price/TBV per share multiples ranging from 1.6x to 1.9x, reflecting Price/TBV per share multiples ranging plus or minus one standard deviation from the 1.8x Price/TBV per share multiple on the regression line, to TBV per share as of March 31, 2016 for PrivateBancorp, as provided by PrivateBancorp management, Goldman Sachs derived implied values per share of common stock of PrivateBancorp on a stand-alone basis ranging from $34.42 to $40.41.

Selected Transactions Analysis

Goldman Sachs reviewed and compared certain publicly available information relating to selected acquisition transactions announced since 2013 in which the target company had an asset value of $5 billion or more and involving target companies in the banking and thrift industry.

Goldman Sachs calculated and compared with respect to each of the selected transactions and the proposed transaction:

•: the implied premia represented by the implied value of the consideration per target company share paid in the applicable transaction relative to the last undisturbed closing share price for the target company prior to the announcement of the applicable transaction, or "One-Day Offer Premia";
•: the implied value of the consideration per target company share paid in the transaction as a multiple of the target company's estimated EPS for its first full fiscal year after the announcement of the applicable transaction, or "Consideration/FY + 1 EPS"; and
•: the implied value of the consideration per target company share paid in the transaction as a multiple of SBV per share, or the "Consideration/SBV per share," and as a multiple of TBV per share, or "Consideration/TBV per share," of the target company as of the last full fiscal quarter prior to the announcement of the applicable transaction.

For purposes of its calculations, Goldman Sachs used estimates for EPS for each target company's first full fiscal year after the announcement of the applicable transaction reflecting the most recent median estimates for such company published by SNL Financial prior to the announcement of the applicable transaction, and Goldman Sachs used SBV per share and TBV per share figures publicly disclosed for each target company for the last quarter end prior to the announcement of the applicable transaction. In performing its calculations with respect to PrivateBancorp and the proposed transaction, Goldman used the closing share price for PrivateBancorp common stock as of June 24, 2016, the 2017 EPS estimate reflected in the PrivateBancorp Financial Forecasts and the most recent median 2017 EPS estimate for PrivateBancorp published by IBES as of June 24, 2016 and the SBV per share and TBV per share information for PrivateBancorp as provided by PrivateBancorp management.

CIBC Selected Companies Analyses

Goldman Sachs reviewed and compared certain financial information for CIBC to corresponding financial information and public market multiples for selected publicly traded companies in the Canadian banking industry.

Goldman Sachs calculated and compared with respect to CIBC and each of the selected companies its closing price per share as of June 24, 2016, on the New York Stock Exchange (except National Bank of Canada, for which the closing share price on the Toronto Stock Exchange was used a translated into US dollars at C$/US$ rate of 0.769):

•: as a multiple of estimated cash EPS for the four quarter period, or the "NTM period," ended April 30, 2017, as a multiple of estimated cash EPS for fiscal year 2016 and as a multiple of estimated cash EPS for fiscal year 2017; and
•: as a multiple of its SBV per share and TBV per share as of its most recently completed fiscal quarter for which SBV per share and TBV per share information was publicly available as of June 24, 2016.

For purposes of its calculations, Goldman Sachs used NTM period, fiscal year 2016 and fiscal year 2017 cash EPS estimates for the selected companies reflecting the most recent median EPS estimates for such companies published by IBES as of June 24, 2016. For CIBC, Goldman Sachs also used the NTM period, fiscal year 2016 and fiscal year 2017 cash EPS estimates reflected in the CIBC Forecasts. Goldman Sachs used SBV per share and TBV per share information for the selected companies and CIBC as publicly disclosed.

Illustrative Present Value of Future Stock Price Analyses for CIBC on Stand-Alone and Pro-Forma Bases

Goldman Sachs performed an illustrative analysis of the implied present value of the future value per share of CIBC common shares on a stand-alone basis and on a pro-forma basis giving effect to the proposed transaction.

Goldman Sachs derived a range of theoretical future values per share for CIBC common shares on a stand-alone basis as of October 31, 2017, 2018 and 2019, by applying illustrative price to EPS multiples of 10.0x and 11.0x to the estimates of CIBC's cash EPS for the fiscal years ending October 31, 2018, 2019 and 2020, respectively, reflected in the CIBC Forecasts. By applying a discount rate of 10.0%, reflecting an estimate of CIBC's cost of equity on a stand-alone basis, Goldman Sachs discounted to present value as of April 30, 2016 both the theoretical future values per share it derived for CIBC on a stand-alone basis and the estimated dividends to be paid per CIBC common share on a stand-alone basis through the end of the applicable year as reflected in the CIBC Forecasts to yield illustrative present values per CIBC common share on a stand-alone basis ranging from $77.05 to $86.12.

Goldman Sachs also derived a range of theoretical future values per share for CIBC common shares on a pro-forma basis (giving effect to the proposed transaction) as of October 31, 2017, 2018 and 2019, by applying illustrative price to cash EPS multiples of 10.5x and 11.5x to the estimates of CIBC's cash EPS for the fiscal years ending October 31, 2018, 2019 and 2020, respectively, reflected in the CIBC Pro-Forma Forecasts. By applying a discount rate of 10.1%, reflecting an estimate of CIBC's cost of equity on a pro-forma basis, Goldman Sachs discounted to present value as of April 30, 2016 both the theoretical future values per share it derived for CIBC on a pro-forma basis and the estimated dividends to be paid per CIBC common share on a pro-forma basis through the end of the applicable year as reflected in the CIBC Pro-Forma Forecasts to yield illustrative present values per common share of CIBC on a pro-forma basis ranging from $78.54 to $87.64.

Goldman Sachs multiplied this range of illustrative present values per CIBC common share on a pro-forma basis by an illustrative transaction exchange ratio of 0.3659 (0.0002 above the final transaction exchange ratio of 0.3657) and added to the result $18.80, the per share cash merger consideration, to derive a range of illustrative present values for the merger consideration of $47.54 to $50.87 per share of common stock of PrivateBancorp.

Illustrative Discounted Dividend Analyses for CIBC on Stand-Alone and Pro-Forma Bases

Using the CIBC Forecasts, Goldman Sachs performed illustrative discounted dividend analyses on CIBC on stand-alone and pro-forma bases to derive ranges of illustrative present values per share of CIBC common shares on stand-alone and pro-forma bases.

Using discount rates ranging from 9.0% to 11.0%, reflecting estimates of the cost of equity for CIBC on a stand-alone basis, derived by application of the Capital Asset Pricing Model, which incorporates certain company-specific inputs, including a beta for the company, as well as certain financial metrics for the United States and, in the case of CIBC, Canadian markets generally, Goldman Sachs derived a range of illustrative equity values for CIBC on a stand-alone basis by discounting to present value as of April 30, 2016, (a) the estimated dividends to be paid by CIBC to its shareholders over the period beginning May 1, 2016, through the end of CIBC's fiscal year ending October 31, 2021, as reflected in the CIBC Forecasts and assuming CIBC maintaining Tier 1 Leverage ratios ranging from 3.5% to 4.5%, and (b) a range of illustrative terminal values for CIBC on a stand-alone basis as of October 31, 2021, calculated by applying illustrative price to cash EPS multiples ranging from 10.0x to 11.0x to the estimate of CIBC's cash EPS for its fiscal year ending October 31, 2022, reflected in the CIBC Forecasts. Goldman Sachs then divided the range of illustrative equity values it derived for CIBC on a stand-alone basis by the total number of fully diluted CIBC common shares outstanding as

Table of Contents

provided by PrivateBancorp management, to derive illustrative present values per common share of CIBC on a stand-alone basis ranging from $81.22 to $99.73.

Using discount rates ranging from 9.1% to 11.1%, reflecting estimates of the cost of equity for CIBC on a pro-forma basis (giving effect to the proposed transaction), derived by application of the Capital Asset Pricing Model, which incorporates certain company-specific inputs, including a beta for the company, as well as certain financial metrics for the United States and, in the case of CIBC on a pro-forma basis, Canadian markets generally, Goldman Sachs derived a range of illustrative equity values for CIBC on a pro-forma basis by discounting to present value as of April 30, 2016, (a) the estimated dividends to be paid by CIBC to the CIBC shareholders and the estimated cash infusion to be made into CIBC over the period beginning May 1, 2016, through the end of CIBC's fiscal year ending October 31, 2021, as well as the dividends and estimated cash infusions that would be made into PrivateBancorp as reflected in the CIBC Forecasts for the period until closing of the proposed transaction (assumed, for illustrative purposes to occur on April 30, 2017) and the CIBC Pro-Forma Forecasts for the periods thereafter and on CIBC maintaining Tier 1 Leverage ratios ranging from 3.5% to 4.5%, and (b) a range of illustrative terminal values for CIBC on a pro-forma basis as of October 31, 2021, calculated by applying illustrative price to cash EPS multiples ranging from 10.5x to 11.5x to the estimate of CIBC's cash EPS for its fiscal year ending October 31, 2022, reflected in the CIBC Pro-Forma Forecasts. Goldman Sachs then divided the range of illustrative equity values it derived for CIBC on a pro-forma basis by the total number of fully diluted CIBC common shares outstanding, increased by the number of CIBC common shares anticipated to be issued in the proposed transaction, as provided by PrivateBancorp management, to derive illustrative present values per common share of CIBC on a pro-forma basis ranging from $83.18 to $100.48.

Goldman Sachs multiplied this range of illustrative present values per common share of CIBC on a pro-forma basis by an illustrative transaction exchange ratio of 0.3659 (0.0002 above the final transaction exchange ratio of 0.3657) and added to the result $18.80, the per share cash merger consideration, to derive a range of illustrative present values for the merger consideration of $49.24 to $55.56 per share of PrivateBancorp common stock.

Regression Analysis for CIBC

Goldman Sachs performed a regression analysis using the price/TBV per share multiples for the selected companies calculated by Goldman Sachs as summarized under "—CIBC Selected Companies Analyses for PrivateBancorp on a Stand-alone Basis" above compared to the estimated fiscal year 2018 return on average tangible common equity, or the "FY 2018E ROATCE," for the selected companies using the median estimates for such companies published by IBES as of June 24, 2016, to derive a regression line reflecting a range of Price/TBV per share multiples at a range of FY 2018E ROATCEs for the selected companies. The FY 2018E ROATCE for CIBC on a stand-alone basis, as reflected in the CIBC Forecasts yielded a regression implied price per common share of CIBC of $78.10. The FY 2018E ROATCE for CIBC on a pro-forma basis as reflected in the CIBC Pro-Forma Forecasts yielded a regression implied price per common share of CIBC of $84.08 as of closing of the proposed transaction (assumed for illustrative purposes to occur on April 30, 2017) corresponding to a Price/TBV per share multiple of 2.3x on the regression line. Goldman Sachs applied illustrative Price/TBV per share multiples ranging from plus or minus one standard deviation from the 2.3x Price/TBV per share multiple on the regression line, to TBV per share of CIBC on a pro-forma basis as of closing of the proposed transaction as reflected in the CIBC Pro-Forma Forecasts and discounted the result to present value as of April 30, 2016, using a discount rate of 10.1%, reflecting an estimate of CIBC's cost of equity on a pro-forma basis, to derive regression implied present values per common share of CIBC on a pro-forma basis ranging from $70.81 to $84.12.

Goldman Sachs multiplied this range of regression implied present values per common share of CIBC on a pro-forma basis by an illustrative transaction exchange ratio of 0.3659 (0.0002 above the final transaction exchange ratio of 0.3657) and added to the result $18.80, the per share cash merger consideration, to derive a range of illustrative implied present values for the merger consideration of $44.71 to $49.58 per share of PrivateBancorp common stock.

General

The preparation of a fairness opinion is a complex process and is not necessarily susceptible to partial analysis or summary description. Selecting portions of the analyses or of the summary set forth above, without considering the analyses as a whole, could create an incomplete view of the processes underlying Goldman Sachs' opinion. In arriving at its fairness determination, Goldman Sachs considered the results of all of its analyses and did not attribute any particular weight to any factor or analysis considered by it. Rather, Goldman Sachs made its determination as to fairness on the basis of its experience and professional judgment after considering the results of all of its analyses. No company or transaction used in the above analyses as a comparison is directly comparable to PrivateBancorp or CIBC or the proposed transaction.

Goldman Sachs prepared these analyses for purposes of providing its opinion to the board of directors of PrivateBancorp that, as of June 29, 2016, the date of its written opinion, and based upon and subject to the factors and assumptions set forth in Goldman Sachs' written opinion, the merger consideration to be paid to the holders (other than CIBC and its affiliates) of the shares of PrivateBancorp common stock pursuant to the merger agreement was fair from a financial point of view to such holders. These analyses do not purport to be appraisals nor do they necessarily reflect the prices at which businesses or securities actually may be sold. Analyses based upon projections of future results are not necessarily indicative of actual future results, which may be significantly more or less favorable than suggested by these analyses. Because these analyses are inherently subject to uncertainty, being based upon numerous factors or events beyond the control of the parties or their respective advisors, none of PrivateBancorp, Goldman Sachs or any other person assumes responsibility if future results are materially different from those forecasted.

The merger consideration to be paid to the holders of the shares of PrivateBancorp common stock pursuant to the merger agreement was determined through arm's-length negotiations between PrivateBancorp and CIBC and was approved by the board of directors of PrivateBancorp. Goldman Sachs provided advice to PrivateBancorp during these negotiations. Goldman Sachs did not, however, recommend any specific amount of consideration to PrivateBancorp or that any specific amount of consideration constituted the only appropriate consideration for the proposed merger.

As described above, Goldman Sachs' opinion was one of many factors taken into consideration by the board of directors of PrivateBancorp in considering the proposed transaction. The foregoing summary does not purport to be a complete description of the analyses performed by Goldman Sachs in connection with the delivery of its fairness opinion to the board of directors of PrivateBancorp and is qualified in its entirety by reference to the written opinion of Goldman Sachs attached as Appendix B to this proxy statement/prospectus.

Goldman Sachs and its affiliates are engaged in advisory, underwriting and financing, principal investing, sales and trading, research, investment management and other financial and non-financial activities and services for various persons and entities. Goldman Sachs and its affiliates and employees, and funds or other entities they manage or in which they invest or have other economic interests or with which they co-invest, may at any time purchase, sell, hold or vote long or short positions and investments in securities, derivatives, loans, commodities, currencies, credit default swaps and other financial instruments of PrivateBancorp, CIBC and any of their respective affiliates and third parties, or any currency or commodity that may be involved in the transaction contemplated by the merger

agreement. Goldman Sachs acted as financial advisor to PrivateBancorp in connection with, and participated in certain of the negotiations leading to, the proposed transaction. Goldman Sachs has provided certain financial advisory and/or underwriting services to PrivateBancorp and/or its affiliates from time to time. In addition, Goldman Sachs has provided certain financial advisory and/or underwriting services to CIBC and/or its affiliates from time to time for which its Investment Banking Division has received, and may receive compensation, which compensation, during the two year period ended June 29, 2016, the date of execution of the merger agreement, was less than $25,000. Goldman Sachs may also in the future provide financial advisory and/or underwriting services to PrivateBancorp, CIBC and their respective affiliates for which its investment banking division may receive compensation.

PrivateBancorp selected Goldman Sachs as its financial advisor because it is an internationally recognized investment banking firm that has substantial experience in transactions similar to the proposed transaction. Pursuant to an engagement letter between PrivateBancorp and Goldman Sachs, PrivateBancorp has agreed to pay Goldman Sachs a transaction fee that is estimated, based on information that is available as of the date of announcement, of approximately $30.6 million, $5.0 million of which was paid at the announcement of the proposed transaction, and the remainder of which is contingent upon consummation of the proposed transaction. In addition, PrivateBancorp agreed to reimburse Goldman Sachs for certain of its expenses, including reasonable attorneys' fees and disbursements, and to indemnify Goldman Sachs and related persons against various liabilities, including certain liabilities under the federal securities laws. During the two year period ended June 29, 2016, the date of the execution of the merger agreement, the Investment Banking Division of Goldman Sachs has not been engaged by PrivateBancorp or its affiliates to provide financial advisory or underwriting services for which Goldman Sachs has received compensation.

Opinion of Sandler

On June 21, 2016, the board of directors of PrivateBancorp retained Sandler to prepare and render to the board, in connection with its consideration of the proposed merger, an opinion as to whether the merger consideration was fair to the holders of PrivateBancorp common stock from a financial point of view.

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

At the meeting of the board of directors of PrivateBancorp held to evaluate the proposed merger, Sandler rendered to the board of directors of PrivateBancorp its oral opinion, subsequently confirmed in writing, to the effect that, as of June 29, 2016, the date of its written opinion, and based upon and subject to the factors set forth in Sandler's written opinion, the merger consideration consisting of $18.80 in cash and 0.3657 common shares of CIBC was fair to the holders of PrivateBancorp common stock from a financial point of view. The full text of Sandler's opinion, dated June 29, 2016, is attached as Appendix C to this proxy statement. The opinion outlines the procedures followed, assumptions made, matters considered and qualifications and limitations on the review undertaken by 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 PrivateBancorp common stock are urged to read the entire opinion carefully in connection with their consideration of the proposed merger.

not constitute a recommendation to any holder of PrivateBancorp common stock as to how such holder of PrivateBancorp common stock should vote at any meeting of stockholders called to consider and vote upon the adoption of the merger agreement and approval of the merger. It does not address the underlying business decision of PrivateBancorp to engage in the merger, the form or structure of the merger or other transactions contemplated in the merger agreement, the relative merits of the merger as compared to any other alternative business strategies that might exist for PrivateBancorp or the effect of any other transaction in which PrivateBancorp might engage, or the fairness of the merger to any other class of securities, creditor or other constituency of PrivateBancorp. 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 or other transactions contemplated by the merger agreement by any PrivateBancorp or CIBC officer, director, or employee, or any class of such persons, if any, relative to the merger consideration to be received by any other stockholder of PrivateBancorp. Sandler's opinion was approved by Sandler's fairness opinion committee.

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

•: the merger agreement;
•: certain publicly available financial statements and other historical financial information of PrivateBancorp that Sandler deemed relevant;
•: certain publicly available financial statements and other historical financial information of CIBC that Sandler deemed relevant;
•: internal financial projections for PrivateBancorp for the years ending December 31, 2016 through December 31, 2022, as provided by the senior management of PrivateBancorp;
•: internal financial projections for CIBC for the fiscal years ending October 31, 2016 through October 31, 2022, as prepared and provided by the senior management of PrivateBancorp;
•: the pro forma financial impact of the merger on CIBC based on certain assumptions relating to transaction expenses, purchase accounting adjustments, a core deposit intangible asset and cost savings, as well as internal financial projections for PrivateBancorp, as owned by CIBC, for the years ending December 31, 2016 through December 31, 2022, as provided by the senior management of PrivateBancorp;
•: the publicly reported historical price and trading activity for PrivateBancorp common stock and CIBC common shares, including a comparison of certain stock market information for PrivateBancorp common stock and CIBC common shares and certain stock indices as well as publicly available information for certain other similar companies, the securities of which are publicly traded;
•: a comparison of certain financial information for PrivateBancorp and CIBC with similar institutions for which information is publicly available;
•: the financial terms of certain recent business combinations in the banking industry (on a regional and nationwide basis), to the extent publicly available;
•: the current market environment generally and the commercial banking environment in particular; and
•: such other information, financial studies, analyses and investigations and financial, economic and market criteria as Sandler considered relevant.

Sandler also discussed with certain members of the senior management of PrivateBancorp the business, financial condition, results of operations and prospects of PrivateBancorp and held similar

Table of Contents

discussions with certain members of senior management of CIBC regarding publicly available information pertaining to the business, financial condition, results of operations and prospects of CIBC.

In performing its review, Sandler relied upon the accuracy and completeness of all of the financial and other information that was available to and reviewed by Sandler from public sources, that was provided to Sandler by PrivateBancorp or CIBC or their respective representatives, or that was otherwise reviewed by Sandler and Sandler assumed such accuracy and completeness for purposes of rendering its opinion, without any independent verification or investigation. Sandler further relied on the assurances of the respective managements of PrivateBancorp and CIBC that they were not aware of any facts or circumstances that would make any of such information inaccurate or misleading. Sandler was not asked to undertake, and did not undertake, an independent verification of any of such information and Sandler did not assume any responsibility or liability for the accuracy or completeness thereof. 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 PrivateBancorp or CIBC, or any of their respective subsidiaries, and Sandler was not furnished with any such evaluations or appraisals. Sandler did not render any opinion or evaluation on the collectability of any assets or the future performance of any loans of PrivateBancorp or CIBC or any of their respective subsidiaries. Sandler did not make an independent evaluation of the adequacy of the allowance for loan losses of PrivateBancorp or CIBC, or the combined entity after the merger, and did not review any individual credit files relating to PrivateBancorp or CIBC or any of their respective subsidiaries. Sandler assumed, with PrivateBancorp's consent, that the respective allowances for loan losses for both PrivateBancorp and CIBC were adequate to cover such losses and will be adequate on a pro forma basis for the combined entity.

In preparing its analyses, Sandler used internal financial projections for PrivateBancorp for the years ending December 31, 2016 through December 31, 2022, as provided by the senior management of PrivateBancorp. In addition, in preparing its analyses Sandler used internal financial projections for CIBC for the fiscal years ending October 31, 2016 through October 31, 2022, as prepared and provided by the senior management of PrivateBancorp. Sandler also received and used in its pro forma analyses certain assumptions relating to transaction expenses, purchase accounting adjustments, a core deposit intangible asset and cost savings, as well as internal financial projections for PrivateBancorp, as owned by CIBC, for the years ending December 31, 2016 through December 31, 2022, as provided by the senior management of PrivateBancorp. With respect to the foregoing information, the management of PrivateBancorp confirmed to Sandler that such information reflected the best currently available projections, estimates and judgment of senior management of the future financial performance of PrivateBancorp and CIBC, as applicable, and Sandler assumed that such performance would be achieved. Sandler expressed no opinion as to such projections, estimates or judgments, or the assumptions on which they are based. Sandler also assumed that there has been no material change in PrivateBancorp's or CIBC's assets, financial condition, results of operations, business or prospects since the date of the most recent financial statements made available to Sandler. Sandler assumed in all respects material to its analysis that PrivateBancorp and CIBC will remain as going concerns for all periods relevant to its analyses.

Sandler also assumed, with PrivateBancorp's consent, that (i) each of the parties to the merger agreement will 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 are true and correct in all material respects, that 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 proposed merger, no delay, limitation, restriction or condition will be imposed that would have an adverse effect on PrivateBancorp, CIBC or the benefits

Table of Contents

contemplated by the merger or any related transaction, and (iii) the proposed merger and any related transaction will 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. Sandler expressed no opinion as to any of the legal, accounting or tax matters relating to the proposed merger or any other transactions contemplated in connection therewith.

Sandler's analyses and opinion are necessarily based on financial, economic, market and other conditions as in effect on, and the information made available to Sandler as of, June 29, 2016, the date of its opinion. Events occurring after such date could materially affect Sandler's opinion. Sandler has not undertaken to update, revise, reaffirm or withdraw its opinion or otherwise comment upon events occurring after the date of its opinion. Sandler expressed no opinion as to the trading values of PrivateBancorp common stock or CIBC common shares at any time or what the value of CIBC common shares would be once it is actually received by the holders of PrivateBancorp common stock.

In rendering its opinion, Sandler performed a variety of financial analyses. The summary below is not a complete description of all the analyses underlying Sandler's opinion or the presentation made by Sandler to the board of directors of PrivateBancorp, but is a summary of the material analyses performed and presented by 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. 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 Sandler's comparative analyses described below is identical to PrivateBancorp or CIBC and no transaction is identical to the proposed 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 merger transaction values, as the case may be, of PrivateBancorp and CIBC and the companies to which they were compared. In arriving at its opinion, Sandler did not attribute any particular weight to any analysis or factor that it considered. Rather, Sandler made qualitative judgments as to the significance and relevance of each analysis and factor. 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, Sandler made its determination as to the fairness of the merger consideration to the holders of PrivateBancorp 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, 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 PrivateBancorp, CIBC, and Sandler. The analyses performed by Sandler are not necessarily indicative of actual values or future results, both of which may be significantly more or less favorable than suggested by such analyses. Sandler prepared its analyses solely for purposes of rendering its opinion and provided such analyses to the board of directors of PrivateBancorp at its June 27, 2016 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, Sandler's analyses do not necessarily reflect the value of PrivateBancorp common stock or the prices at which PrivateBancorp or CIBC common shares may be sold at any time. The analyses of

Table of Contents

Sandler and its opinion were among a number of factors taken into consideration by the board of directors of PrivateBancorp in making its determination to approve the merger agreement and the analyses described below should not be viewed as determinative of the decision of the board of directors of PrivateBancorp or senior management with respect to the fairness of the merger.

Summary of Proposed Merger Consideration and Implied Transaction Metrics

Sandler reviewed the financial terms of the proposed merger. Pursuant to the terms of the merger agreement, upon the effective time of the merger, each share of PrivateBancorp common stock issued and outstanding immediately prior to the effective time, other than certain shares as specified in the merger agreement, will be converted into the right to receive, without interest, merger consideration consisting of 0.3657 CIBC common shares and $18.80 in cash. For purposes of this analysis, Sandler utilized a transaction value (inclusive of the value of consideration to holders of in-the-money options, restricted stock awards, restricted stock units and performance stock units, in each case that were expected by PrivateBancorp management to be vested upon closing of the proposed merger) of approximately $3.82 billion(1), or a transaction price per share of approximately $47.00. Based upon financial information for PrivateBancorp as of March 31, 2016 or for the twelve months ended March 31, 2016, or LTM, (unless otherwise indicated), Sandler calculated the following implied transaction metrics.


Transaction Price / LTM Earnings Per Share			19.4x
Transaction Price / Median Analyst 2016E Earnings Per Share			18.4x
Transaction Price / Median Analyst 2017E Earnings Per Share			17.1x

Analysis of Selected Merger Transactions

Sandler reviewed a group of selected merger and acquisition transactions. The group consisted of nine nationwide bank and thrift transactions announced between January 1, 2014 and June 24, 2016 with over $1 billion in reported deal value, or the Precedent Transactions.

Using the latest publicly available information prior to the announcement of the relevant transaction, Sandler reviewed the following quantitative transaction metrics: transaction price to last twelve months earnings per share, transaction price to estimated earnings per share for the year in which the relevant transaction was announced, transaction price to book value per share, transaction price to tangible book value per share, tangible book premium to core deposits, and 1-day market premium. Sandler compared the indicated transaction metrics for the proposed merger, based on an aggregate transaction value of approximately $3.82 billion, or a transaction price per share of approximately $47.00, resulting from the closing price of CIBC common shares on June 24, 2016 of $77.07, to the high, low, mean and median metrics of the Precedent Transactions.

Net Present Value Analyses

Sandler performed an analysis that estimated the net present value per share of PrivateBancorp common stock using internal projections for PrivateBancorp on a stand-alone basis for the years ending December 31, 2016 through December 31, 2022, as provided by the management of PrivateBancorp. To approximate the terminal value of PrivateBancorp common stock at December 31, 2022, Sandler applied price to 2022 earnings multiples ranging from 12.0x to 22.0x and multiples of December 31, 2022 tangible book value ranging from 135% to 210%. The terminal values were then discounted to

present values using different discount rates ranging from 9.5% to 12.5%, which were chosen to reflect different assumptions regarding required rates of return of holders or prospective buyers of PrivateBancorp common stock and which were derived by application of the Capital Asset Pricing Model, which incorporates certain company-specific inputs, including a beta for the company, as well as certain financial metrics for the United States markets generally. As illustrated in the following tables, the analysis indicated an imputed range of values per share of PrivateBancorp common stock on a stand-alone basis of $21.78 to $45.43 when applying multiples of earnings and $22.82 to $40.88 when applying multiples of tangible book value.

Sandler also considered and discussed with the board of directors of PrivateBancorp how this analysis would be affected by changes in the underlying assumptions, including variations with respect to earnings per share. To illustrate this impact, Sandler performed a similar analysis, assuming PrivateBancorp's earnings per share varied from 15% above estimates to 15% below estimates. This analysis resulted in the following range of per share values for PrivateBancorp common stock, applying the price to 2022 earnings multiples range of 12.0x to 22.0x referred to above and a discount rate of 11.0%.

Sandler also performed an analysis that estimated the net present value per CIBC common share, using projections for CIBC on a stand-alone basis for the fiscal years ending October 31, 2016 through October 31, 2022, as provided by PrivateBancorp management. To approximate the terminal value of CIBC common shares at October 31, 2022, Sandler applied price to 2022 earnings multiples ranging from 10.0x to 12.5x and multiples of October 31, 2022 tangible book value ranging from 180% to 230%.

In connection with its analyses, Sandler considered and discussed with the board of directors of PrivateBancorp how the present value analyses would be affected by changes in the underlying assumptions. 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 Merger Analysis

Sandler analyzed certain potential pro forma effects of the merger, based on the following assumptions: (i) the merger closes on April 30, 2017 and (ii) the merger consideration has a value of $47.00. Sandler also utilized the following: (a) internal financial projections of PrivateBancorp, as owned by CIBC, as provided by PrivateBancorp management, (b) financial projections for CIBC, as provided by PrivateBancorp management, (c) purchase accounting adjustments provided by PrivateBancorp management of (i) a gross credit mark of $232 million, or 1.7% of gross loans as of March 31, 2016, (ii) accumulated other comprehensive income adjustment on PrivateBancorp's

Table of Contents

portfolio of $53.2 million, amortized over 4.5 years, and (iii) a core deposit intangible asset created at 1.5% of core deposits, or $14 billion, amortized over 7 years using sum-of-the-years digits method; (d) cost savings projections as provided by PrivateBancorp management; (e) estimated pre-tax one-time transaction costs and expenses as provided PrivateBancorp management; and (f) an annual pre-tax opportunity cost of cash as provided by PrivateBancorp management. The analysis indicated that the merger could be:

•: dilutive to CIBC's estimated adjusted earnings per share (excluding one-time transaction costs and expenses) in the fiscal years ended October 31, 2017 through 2020 and accretive to CIBC's estimated adjusted earnings per share in the fiscal years ended October 31, 2021 through 2022;
•: dilutive to CIBC's estimated cash earnings per share (excluding one-time transaction costs and expenses) in the fiscal years ended October 31, 2017 through 2018, neutral to CIBC's estimated cash earnings per share (excluding one-time transaction costs and expenses) in the fiscal year ended October 31, 2019, and accretive to CIBC's estimated cash earnings per share in the fiscal years ended October 31, 2020 through 2022; and
•: dilutive to estimated tangible book value per CIBC common share at closing and in the fiscal years ended October 31, 2017 through 2022.

In connection with this analysis, Sandler considered and discussed with the board of directors of PrivateBancorp 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 merger, and noted that the actual results achieved by the combined company may vary from projected results and the variations may be material.

Sandler's Relationship

Sandler was retained by the PrivateBancorp board of directors to prepare and render to the board of directors of Privatebancorp, in connection with its consideration of the proposed merger, an opinion as to whether the merger consideration was fair to the holders of PrivateBancorp's common stock from a financial point of view. Sandler received a $1.0 million fee from PrivateBancorp as a result of rendering its opinion, which became payable on June 29, 2016. PrivateBancorp has also agreed to indemnify Sandler against certain liabilities arising out of Sandler's engagement and to reimburse Sandler for certain of its out-of-pocket expenses incurred in connection with Sandler's engagement.

In the ordinary course of its business as a broker-dealer, Sandler may purchase securities from or sell securities to PrivateBancorp, CIBC or their respective affiliates. Sandler may also actively trade the securities of PrivateBancorp or CIBC for its own account and for the accounts of its customers and, accordingly, may at any time hold a long or short position in such securities.

Projected Financial Information

In connection with PrivateBancorp's regular strategic planning process and with the merger, PrivateBancorp's management prepared financial projections of revenue, net income and EPS for fiscal years 2016 through 2022 (such projections, the "projections"). These projections were provided to PrivateBancorp's board of directors and Goldman Sachs and Sandler, in connection with their respective analyses of the merger. PrivateBancorp does not as a matter of course make public long-term projections as to future revenues, earnings or other results due to, among other reasons, the uncertainty of the underlying assumptions and estimates. A summary of the projections is included below to give PrivateBancorp's stockholders access to certain nonpublic information provided to Goldman Sachs and Sandler for purposes of their respective financial analyses summarized above under "Opinions of PrivateBancorp's Financial Advisors." The inclusion of the projections should not be regarded as an indication that PrivateBancorp or its board of directors, Goldman Sachs, Sandler or any

Table of Contents

other recipient of this information considered, or now considers, it to be an assurance of the achievement of future results.

PrivateBancorp advised the recipients of the projections that its internal financial forecasts upon which the projections were based are subjective in many respects. The projections reflect numerous assumptions with respect to company performance, industry performance, general business, economic, market and financial conditions and other matters, many of which are difficult to predict, subject to significant economic and competitive uncertainties and beyond PrivateBancorp's control. As a result, there can be no assurance that the projections will be realized or that actual results will not be significantly higher or lower than projected.

The projections were not prepared with a view toward public disclosure or toward compliance with United States generally accepted accounting principles ("GAAP"), published guidelines of the SEC or the guidelines established by the American Institute of Certified Public Accountants for preparation and presentation of prospective financial information. The prospective financial information included in this proxy statement (including the projections) has been prepared by, and is the responsibility of, PrivateBancorp's management. Ernst & Young LLP ("E&Y"), PrivateBancorp's independent registered public accounting firm, has neither examined, compiled nor performed any procedures with respect to the accompanying prospective financial information (including the projections), and accordingly, E&Y does not express an opinion or any other form of assurance with respect thereto. The E&Y report incorporated by reference in this proxy statement relates to PrivateBancorp's historical financial information. It does not extend to the prospective financial information contained herein and should not be read to do so.

Projections of this type are based on estimates and assumptions that are inherently subject to factors such as company performance, industry performance, general business, economic, regulatory, market and financial conditions, as well as changes to the business, financial condition or results of operations of PrivateBancorp, including the factors described under "Cautionary Statement Concerning Forward-Looking Statements," which factors may cause the projections or the underlying assumptions to be inaccurate. In addition, the projections are based on certain assumptions regarding PrivateBancorp's ongoing business activities. Since the projections cover multiple years, such information by its nature becomes less reliable with each successive year.

The following is a summary of the projections:

Neither CIBC nor PrivateBancorp, as a matter of course, makes public projections as to future earnings or other results due to, among other reasons, the uncertainty of the underlying assumptions and estimates. In connection with the proposed transaction, however, PrivateBancorp prepared and provided to Goldman Sachs and Sandler O'Neill certain unaudited prospective financial analyses and forecasts with respect to CIBC on a stand-alone basis reflecting a consensus of equity analysts' estimates for 2016 and 2017, as extrapolated by management of PrivateBancorp for periods thereafter. That information is included below in this proxy statement/prospectus. Goldman Sachs and Sandler O'Neill reviewed this unaudited prospective financial information in connection with preparing their analyses of the fairness, from a financial point of view, of the merger consideration to PrivateBancorp's stockholders, as described above under "The Merger—Opinions of PrivateBancorp's Financial Advisors." The unaudited prospective information set forth below was prepared by PrivateBancorp for PrivateBancorp's internal use and is subjective in many respects. This information was not prepared by CIBC or with any involvement on the part of CIBC. The inclusion of this information in this proxy statement/prospectus should not be regarded as an indication that any of CIBC, PrivateBancorp, Goldman Sachs or Sandler O'Neill, their respective representatives or any other recipient of this information considered, or now considers, it to be predictive of actual future results, or that it should be construed as financial guidance, and it should not be relied on as such.

While presented with numeric specificity, the unaudited prospective financial information below reflects certain estimates and assumptions made by PrivateBancorp with respect to CIBC's business, all of which are difficult to predict and many of which are beyond CIBC's control. This unaudited prospective financial information includes assumptions as to certain macroeconomic conditions, such as future growth rates and interest rate variations, that are subject to change and subjective judgment, and thus is susceptible to multiple interpretations. CIBC was not involved in the preparation of the unaudited prospective financial information and gives no assurance that such information or the underlying estimates and assumptions will be realized. CIBC and PrivateBancorp do not intend to, and each disclaims any obligation to, make publicly available any update or other revisions regarding the unaudited prospective financial information to correct any information or assumptions with which CIBC does not agree, or to update such information to reflect circumstances arising after its preparation or to reflect changes in general economic or industry conditions. Importantly, neither the unaudited prospective financial information with respect to CIBC nor the consensus of equity analysts' estimates

Table of Contents

for 2016 and 2017 used by PrivateBancorp in preparing that information, contemplated completion of the proposed transaction. Accordingly, the unaudited prospective financial information does not give effect to the merger, including the impact of negotiating or executing the merger agreement, the expenses that may be incurred in connection with consummating the merger, the potential synergies that may be achieved by the combined company as a result of the merger or the effect of any business or strategic decisions or actions which would likely have been taken if the merger agreement had not been executed, but which were instead altered, accelerated, postponed or not taken in anticipation of the merger.

Actual results will differ from those set forth below, and the differences may be material. Important factors that may affect actual results and cause the unaudited prospective financial information to be inaccurate include, but are not limited to, risks and uncertainties relating to CIBC's business, industry performance, general business and economic conditions, customer requirements, competition and adverse changes in applicable laws, regulations or rules. For other factors that could cause actual results to differ, please see the sections entitled "Risk Factors" and "Cautionary Statement Regarding Forward-Looking Statements" in this proxy statement/prospectus and in CIBC's Annual Report on Form 40-K filed for the fiscal year ended October 31, 2015, as filed December 3, 2015, and the other reports filed by CIBC with the SEC.

The unaudited prospective financial information does not take into account any circumstances or events occurring after the date it was prepared. There can be no assurance that, had the unaudited prospective financial information been prepared as of the date of this proxy statement/prospectus, similar estimates and assumptions would be used. In addition, since the unaudited prospective financial information covers multiple years, such information by its nature becomes less predictive with each successive year.

None of CIBC, PrivateBancorp, Goldman Sachs or Sandler O'Neill, or their respective affiliates, officers, directors, advisors or other representatives has made, makes or is authorized in the future to make any representation to any shareholder of CIBC or PrivateBancorp or other person regarding CIBC's ultimate performance compared to the information contained in the unaudited prospective financial information or that the forecasted results will be achieved. The summary of the unaudited prospective financial information included below is being provided solely because it was made available to the financial advisors to the PrivateBancorp board of directors in connection with the merger.

The following table presents prospective financial analyses and forecasts with respect to CIBC on a stand-alone basis reflecting a consensus of equity analysts' estimates for 2016 and 2017, as extrapolated by management of PrivateBancorp for periods thereafter.

The unaudited prospective financial information was not prepared with a view toward public disclosure, nor was it prepared with a view toward compliance with GAAP, IFRS, published guidelines of the SEC or the guidelines established by the American Institute of Certified Public Accountants for preparation and presentation of prospective financial information. Neither CIBC's independent registered public accounting firm, nor any other independent accountants, have compiled, examined or performed any procedures with respect to the unaudited prospective financial information contained herein, nor have they expressed any opinion or any other form of assurance on such information or its achievability. The independent registered public accountant reports included in this proxy statement/prospectus relate to CIBC's historical financial information. They do not extend to the unaudited prospective financial information and should not be read to do so.

In light of the foregoing, and considering that PrivateBancorp's special meeting will be held after the unaudited prospective financial information was prepared, as well as the uncertainties inherent in any forecasted information, PrivateBancorp and CIBC stockholders are cautioned not to place unwarranted reliance on such information, and CIBC and PrivateBancorp urge all PrivateBancorp and CIBC stockholders to review CIBC's most recent SEC filings for a description of CIBC's reported financial results. See section titled "Where You Can Find More Information."

CIBC's Reasons for the Merger

On June 28, 2016, the CIBC board of directors approved the merger and authorized certain executive officers to sign and deliver the merger agreement on CIBC's behalf. In the course of making its decision to approve the merger, the CIBC board of directors consulted with CIBC's management and internal legal counsel, as well as its financial advisors, CIBC World Markets Inc. and J.P. Morgan Securities LLC, and considered a number of factors.

CIBC has been seeking opportunities to expand its existing U.S. commercial and private banking businesses as part of its overall strategy of creating a financially strong, technologically innovative, and relationship-oriented bank, while also providing important business, geographic and earnings diversification for CIBC. Combined with CIBC's existing U.S. capital markets, corporate banking and wealth management franchise, CIBC's management believes that the merger will create a strong platform to serve all of the combined enterprises' client needs throughout North America as well as add the capability of accepting deposits in the United States. In addition, CIBC's management believes that CIBC's financial strength, broad suite of products and services, and scalable technology platform will help accelerate PrivateBancorp's growth profile in an important segment of the U.S. banking market.

Management and Board of Directors of CIBC After the Merger

The current directors and senior officers of CIBC are expected to continue in their current positions upon completion of the merger, other than as may be publicly announced by CIBC in the normal course. The President & Chief Executive Officer of PrivateBancorp, Larry D. Richman, is expected to join the executive committee of CIBC, reporting directly to the President & Chief Executive Officer of CIBC, and to assume the role of Head of CIBC's U.S. region, which will include PrivateBank and certain of CIBC's current U.S. businesses. In addition, subject to certain conditions, the merger agreement entitles PrivateBancorp to appoint one independent director on CIBC's board of directors and to nominate such person for election as a director of CIBC at CIBC's first annual meeting of shareholders following the effective date of the merger.

Information about the current CIBC directors and executive officers can be found in the documents listed under "Where You Can Find More Information."

Interests of PrivateBancorp's Directors and Executive Officers in the Merger

In considering the recommendation of PrivateBancorp's board of directors that you vote to approve the merger agreement proposal, you should be aware that some of PrivateBancorp's directors and executive officers have economic interests in the merger that are different from, or in addition to, those of PrivateBancorp's stockholders generally. PrivateBancorp's board of directors was aware of these interests and considered them, among other matters, in reaching its decisions to (i) approve the merger agreement and the transactions contemplated thereby and (ii) recommend that the stockholders of PrivateBancorp approve the merger agreement proposal. The transactions contemplated by the merger agreement will constitute a "change in control" for purposes of the PrivateBancorp employment agreements and compensation and benefit plans described below.

Certain Assumptions

Except as otherwise specifically noted, for purposes of quantifying the potential payments and benefits described in this section, the following assumptions were used:

•: The relevant price per share of PrivateBancorp common stock is $43.81, which is the average closing price per share of PrivateBancorp's common stock as quoted on the NASDAQ over the first five business days following the first public announcement of the merger on June 29, 2016;
•: The effective time is August 11, 2016, which is the assumed date of the closing of the merger solely for purposes of the disclosure in this section; and
•: Each executive officer of PrivateBancorp is terminated by PrivateBancorp without "cause" or resigns for "good reason" (as such terms are defined in the relevant PrivateBancorp plans and agreements), in either case immediately following the assumed effective time of August 11, 2016.

The description included below, including quantification of potential payments and benefits, takes into account that PrivateBancorp may amend outstanding equity award agreements to provide that change in control termination protection will continue through the final vesting date (i.e., be extended beyond the second anniversary of the completion of the merger), but does not take into account certain other compensation actions that PrivateBancorp is permitted to take prior to the completion of the merger, as described in the section entitled "The Merger Agreement—Covenants and Agreements—Conduct of Businesses Prior to the Completion of the Merger" beginning on page 109 of this proxy statement/prospectus.

Equity Compensation

Treatment of Stock Options

At the effective time, each PrivateBancorp option that is outstanding and unexercised immediately prior to the effective time shall be converted automatically into an option to purchase CIBC shares on the terms specified in the merger agreement (including that such CIBC option will have the same vesting terms as the corresponding PrivateBancorp option). Each converted, unvested PrivateBancorp option will vest in full upon the holder's termination without cause or resignation for good reason at any time after the effective time of the merger.

Treatment of Restricted Stock Units

At the effective time, each PrivateBancorp restricted stock unit award that is outstanding immediately prior to the effective time shall (i) if unvested, be converted automatically into a cash-settled CIBC restricted stock unit award on the terms specified in the merger agreement (including that such CIBC restricted stock unit award shall have the same vesting terms as the corresponding PrivateBancorp restricted stock unit award), and (ii) if vested (including all restricted

Table of Contents

stock units held by non-employee directors, whether vested or unvested as of the date of the merger agreement, which shall be vested and settled within 10 days after the effective time), be cancelled and converted automatically into the right to receive a cash payment equivalent in value to the merger consideration, as determined in accordance with the merger agreement, in respect of each share underlying such award plus a cash payment equal to accumulated but unpaid dividend equivalents; provided, that any such vested award that does not provide for settlement upon a change in control shall instead be converted pursuant to clause (i) above. Each converted PrivateBancorp restricted stock unit award will vest in full upon the holder's termination without cause or resignation for good reason at any time after the effective time of the merger.

Treatment of Performance Share Units

At the effective time, each PrivateBancorp performance share unit award that is outstanding immediately prior to the effective time shall (i) if unvested, be converted automatically into a CIBC cash-settled restricted stock unit award on the terms specified in the merger agreement (including that such CIBC restricted stock unit award will have the same time-based vesting terms as the corresponding PrivateBancorp performance share unit award and shall not be subject to performance-based vesting conditions), and (ii) if vested, be cancelled and converted automatically into the right to receive a cash payment equivalent in value to the merger consideration, as determined in accordance with the merger agreement, in respect of each share underlying such award plus a cash payment equal to accumulated but unpaid dividend equivalents; provided, that any such vested award that does not provide for settlement upon a change in control shall instead be converted pursuant to clause (i) above. For purposes of the foregoing, the number of shares of PrivateBancorp common stock underlying each performance share unit award shall be determined by assuming that the applicable performance goals are achieved at the maximum level. Each converted PrivateBancorp performance share unit award will vest in full upon the holder's termination without cause or resignation for good reason at any time after the effective time of the merger.

Treatment of Deferred Stock Units

See the section entitled "Interests of PrivateBancorp's Directors and Executive Officers in the Merger—Quantification of Potential Payments and Benefits to PrivateBancorp's Named Executive Officers in Connection with the Merger" beginning on page 85 of this proxy statement/prospectus for an estimate of the value of the unvested equity awards held by each of PrivateBancorp's named executive officers that would become vested upon a qualifying termination following the effective time. Based on the assumptions described above under "Interests of PrivateBancorp's Directors and Executive Officers in the Merger—Certain Assumptions", (i) the estimated aggregate value of the unvested equity awards held by PrivateBancorp's four executive officers who are not named executive officers that would become vested upon a qualifying termination immediately following the effective time is $6,535,800 and (ii) the estimated aggregate value of the PrivateBancorp restricted stock unit awards held by PrivateBancorp's ten non-employee directors that would become vested at the effective time is $535,796. For more information on equity holdings of PrivateBancorp non-employee directors and executive officers, see the table entitled "Beneficial Ownership of PrivateBancorp Common Stock" on page 120 of this proxy statement/prospectus.

Employment and Retention Agreements

Larry D. Richman

Concurrently with the execution of the merger agreement, Mr. Richman entered into a new employment agreement with CIBC, which will become effective, and supersede his existing employment agreement with PrivateBancorp, upon the closing of the merger.

CIBC Employment Agreement with Larry D. Richman. The new employment agreement between CIBC and Mr. Richman provides for his service as Senior Executive Vice-President, CIBC, President & CEO of each of PrivateBank and Holdco, and Head of CIBC U.S. Region for a term of three years following the closing date. Following the initial three-year term, Mr. Richman will continue to serve as Executive Chairman of the board of directors of each of PrivateBank and Holdco for a term of two years. Under the agreement, during the initial three-year term, Mr. Richman will have an annual base salary of $1,030,000 (which may be increased but not decreased) and annual target total incentive compensation of $3,720,000 (which may be increased but not decreased). During Mr. Richman's service as Executive Chairman under the agreement, his annual base salary and annual target total incentive compensation will be, in each case, 50% of that in effect immediately prior to the end of the initial three-year term. During the entire term of the agreement, provided that he meets applicable eligibility requirements, Mr. Richman will be entitled to receive his existing PrivateBancorp benefits package, as amended from time to time, or such other benefits that are no less favorable in the aggregate than such PrivateBancorp benefits package.

As described below under "Superseded Employment Agreement with Larry D. Richman," under Mr. Richman's existing employment agreement, he would have the right to resign for any reason during the 90-day period beginning on the first anniversary of a change in control and receive a cash severance payment (calculated assuming the qualifying termination occurred on the date of the merger agreement) of $8,190,000. The right to resign for any reason and receive severance was not preserved in the severance provisions in the new employment agreement (which are described below). The new agreement provides that an amount equal to a total of $8,200,000 consisting of $2,050,000 in deferred cash and $6,150,000 in deferred share units shall be credited to a deferred compensation account for Mr. Richman's benefit. The deferred cash award will vest, subject to continued employment, on the date that is three months following the closing date and the deferred share unit award will vest, subject to continued employment, with respect to one-third of the award, on the date that is nine months following the closing date and, with respect to the remaining two-thirds of the award, on the date that is eighteen months following the closing date, or, with respect to both the deferred cash and deferred share units, upon a termination of Mr. Richman's employment prior to the scheduled vesting date for any reason other than voluntary resignation without good reason and subject to the execution and effectiveness of a release of claims. This vesting schedule is generally consistent with the vesting schedule for retention awards made to other PrivateBancorp executive officers, as described below under "Interests of PrivateBancorp's Directors and Executive Officers in the Merger—Retention Arrangements with PrivateBancorp Executive Officers". Both awards, if and to the extent vested, shall be payable to Mr. Richman upon his future separation from service. Mr. Richman will also be provided with a supplementary executive retirement arrangement.

If Mr. Richman's employment is terminated without "cause" or for "good reason" during the term of the new employment agreement, he will be entitled to receive, subject to his execution and the effectiveness of a general release, (i) cash severance in an amount equal to 1.5 multiplied by the sum of (A) base salary and (B) an amount equal to the average of the annual cash bonus amounts paid to Mr. Richman in relation to the three years following the closing date and prior to the year in which termination occurs (or, if less than three, the number of annual performance periods actually completed prior to the termination date) or, in the case of a termination occurring prior to an annual cash bonus being awarded, the greater of (x) the most recent annual incentive awarded to Mr. Richman

Table of Contents

by PrivateBancorp prior to the closing date and (y) 30% of Mr. Richman's annual target total incentive compensation as a CIBC employee; (ii) payment of a prorated annual incentive compensation amount based on the total incentive compensation earned by Mr. Richman for the year prior to termination, with proration based on the portion of the year of termination during which he was employed; and (iii) a lump sum payment equal to 18 months of the applicable employer portion of healthcare premium contributions. Mr. Richman will also be covered by CIBC's Change of Control Policy, as amended from time to time, and to the extent that Mr. Richman becomes entitled to the payment of benefits pursuant to such policy upon a termination of employment, the terms of such policy will govern and Mr. Richman will not be entitled to the payment of benefits described in the preceding sentence in connection with such termination of employment.

Consistent with Mr. Richman's existing employment agreement with PrivateBank and PrivateBancorp, as described below, Mr. Richman will be entitled to receive a full gross-up for any excise tax imposed on the payments and benefits to Mr. Richman in connection with the merger (including any such payments and benefits relating to his termination of employment) by reason of Sections 4999 and 280G of the U.S. Internal Revenue Code.

The agreement also includes an indefinite confidentiality covenant and non-competition and non-solicitation covenants that apply during employment and for one year following termination of employment.

Superseded PrivateBancorp Employment Agreement with Larry D. Richman. Mr. Richman is party to an existing employment agreement with PrivateBank and PrivateBancorp. As described above, this existing employment agreement will be superseded by the new employment agreement that Mr. Richman has entered into with CIBC when it becomes effective at the effective time.

Under the existing agreement, upon a termination of Mr. Richman's employment without "cause" or for "good reason" (including Mr. Richman's resignation for any reason during the ninety day period beginning on the first anniversary of the change in control) during the period beginning six months prior to, and ending on the second anniversary of, a change in control, Mr. Richman would be entitled to the following payments and benefits, subject to the execution and effectiveness of a general release of claims: (i) cash severance in an amount equal to 300% of sum of (a) base salary, plus (b) the greater of (x) the prior year's actual bonus and (y) the average of the sum of the bonus amounts earned with respect to the three calendar years immediately preceding the calendar year of termination, (ii) 36 months of group health plan coverage at the active employee rate; (iii) outplacement services for 24 months; and (iv) a prorated bonus based on the prior year's actual bonus and the portion of the year of termination during which Mr. Richman was employed.

The existing agreement provides that Mr. Richman will be entitled to a full gross-up if the payments and benefits to Mr. Richman in connection with a change in control would be subject to an excise tax by reason of Sections 4999 and 280G of the U.S. Internal Revenue Code.

The existing agreement also includes an indefinite confidentiality covenant and non-competition and non-solicitation covenants that apply during employment and for one year following termination of employment.

Employment Agreements with Named Executive Officers other than Mr. Richman

Each named executive officer other than Mr. Richman is also party to an existing employment agreement with PrivateBank. Under the existing agreements, upon a termination of the officer's employment without "cause" or for "good reason" during the period beginning six months prior to, and ending on the second anniversary of, a change in control, the officer would be entitled to the following payments and benefits, subject to the execution and effectiveness of a general release of claims: (i) cash severance in an amount equal to 200% of the sum of (a) base salary, plus (b) the greater of (x) the

Table of Contents

prior year's actual bonus and (y) the average of the sum of the bonus amounts earned with respect to the three calendar years immediately preceding the calendar year of termination, (ii) 24 months of group health plan coverage at the active employee rate; (iii) outplacement services for 12 months; and (iv) a prorated bonus based on the prior year's actual bonus and the portion of the year of termination during which the officer was employed.

Each existing agreement includes a modified gross-up provision providing that the officer will be entitled to a full gross-up if the payments and benefits to the officer in connection with a change in control would be subject to an excise tax by reason of Sections 4999 and 280G of the U.S. Internal Revenue Code and exceed the threshold level for application of such tax by more than 10%; if such excess equals or is less than 10%, the payments will instead be reduced below the threshold.

The existing agreements also include an indefinite confidentiality covenant and non-competition and non-solicitation covenants that apply during employment and for one year following termination of employment.

Employment Agreements with Other Executive Officers

The four executive officers who are not named executive officers are party to existing employment agreements with PrivateBank, the terms of which are the same in all material respects as the terms of the existing employment agreements with the named executive officers (other than Mr. Richman) as described above, except that (i) the cash severance percentage is 250% for one of the officers and 150% for the other three officers and (ii) the number of months of group health plan coverage at the active employee rate is 24 for two of the officers and 18 for the other two officers.

Two of the existing agreements provide that if the payments and benefits to the officer under the agreement in connection with a change in control would be subject to an excise tax by reason of Sections 4999 and 280G of the U.S. Internal Revenue Code then such payments and benefits will be reduced to one dollar below the threshold level for application of the tax, unless such reduced amount is less than the net amount of such payments and benefits after payment of the excise tax, in which case no reduction will be made. The other existing agreements include the same modified gross-up provision described above with respect to named executive officers other than Mr. Richman.

Based on the assumptions described above under "Interests of PrivateBancorp's Directors and Executive Officers in the Merger—Certain Assumptions", the estimated aggregate cash severance (including prorated bonus) payable to PrivateBancorp's four executive officers who are not named executive officers upon a qualifying termination following the effective time is $6,251,749.

Retention Arrangements with PrivateBancorp Executive Officers

Messrs. Killips, Hague, Lubin and Ms. Case (our named executive officers, other than Mr. Richman) have each been granted a retention award in the amount of $1,200,000, $1,000,000, $1,000,000 and $900,000, respectively, from the retention pool established by PrivateBancorp and CIBC in connection with the merger. In addition, the four executive officers who are not named executive officers have been granted retention awards in the aggregate amount of $3,575,000. Each retention

Table of Contents

award is in the form of 25% cash and 75% cash-settled CIBC restricted stock units. The cash portion of each award vests, subject to continued employment, through the date that is three months following the closing date and the restricted stock unit portion of the award vests, subject to continued employment, with respect to one-third of the units, on the date that is nine months following the closing date and, with respect to the remaining two-thirds of the units, on the date that is eighteen months following the closing date, or, with respect to both parts of the award, upon a termination of employment without cause or for good reason or due to death or disability on or after the closing date and prior to the scheduled vesting date.

Indemnification and Insurance

Pursuant to the terms of the merger agreement, PrivateBancorp directors, officers and employees will be entitled to certain ongoing indemnification and coverage under directors' and officers' liability insurance policies following the merger. Such indemnification and insurance coverage is further described in the section entitled "The Merger Agreement—Covenants and Agreements—Indemnification and Directors' and Officers' Insurance" beginning on page 115 of this proxy statement/prospectus.

Quantification of Potential Payments and Benefits to PrivateBancorp's Named Executive Officers in Connection with the Merger

The information set forth in the table below is being provided in order to comply with Item 402(t) of the SEC's Regulation S-K, which requires disclosure of information about certain compensation for each "named executive officer" of PrivateBancorp that is based on, or otherwise relates to, the merger ("merger-related compensation"). As described under the caption "Interests of PrivateBancorp's Directors and Executive Officers in the Merger" above, Mr. Richman has entered into a new employment arrangement with CIBC that will become effective upon the closing of the merger. The merger-related compensation described below is based on the named executive officers' existing employment agreements with PrivateBancorp and/or PrivateBank, existing PrivateBancorp equity award plans and agreements, retention agreements entered into with named executive officers other than Mr. Richman in connection with the merger and the merger agreement. It does not include amounts payable to Mr. Richman under the new employment agreement with CIBC following the closing of the merger (including (i) post-closing salary, annual incentive compensation, and other compensation and benefits to be provided under Mr. Richman's new employment agreement with CIBC, and (ii) severance payable to Mr. Richman upon a qualifying termination pursuant to his new employment agreement with CIBC). For additional details regarding the terms of the payments and benefits that Mr. Richman will be entitled to receive under his new employment arrangement with CIBC, as well as terms of the payments and benefits described below, see the discussion under the caption "Interests of PrivateBancorp's Directors and Executive Officers in the Merger" above.

The amounts shown in the table below are estimates based on multiple assumptions that may or may not actually occur or be accurate on the relevant date, including the assumptions described below and in the footnotes to the table, and do not reflect certain compensation actions that may occur before completion of the merger, including certain compensation actions that PrivateBancorp is permitted to take prior to the completion of the merger, as described in the section entitled "The Merger Agreement—Covenants and Agreements—Conduct of Businesses Prior to the Completion of the Merger" beginning on page 109 of this proxy statement/prospectus. For purposes of calculating such amounts, the following assumptions were used:

•: The relevant price per share of PrivateBancorp common stock is $43.81, which is the average closing price per share of PrivateBancorp's common stock as quoted on the NASDAQ over the first five business days following the first public announcement of the merger on June 29, 2016;

Table of Contents

•: The effective time is August 11, 2016, which is the assumed date of the closing of the merger solely for purposes of the disclosure in this section; and
•: Each executive officer of PrivateBancorp is terminated by PrivateBancorp without "cause" or resigns for "good reason" (as such terms are defined in the relevant PrivateBancorp plans and agreements), in either case immediately following the assumed effective time of August 11, 2016.

Consists of (a) cash severance in an amount equal to 200% (300% for Mr. Richman) of the sum of (i) base salary, plus (ii) greater of (x) the prior year's actual bonus and (y) average of the sum of the bonus amounts earned with respect to the three calendar years immediately preceding the calendar year of termination, and (b) a prorated bonus based on the prior year's actual bonus and the portion of the year of termination during which the officer was employed. All such amounts are "double trigger" and payable only upon a termination without cause or resignation for good reason (in the case of Mr. Richman, including resignation for any reason during the ninety-day period following the first anniversary of the effective time) during the period beginning six months prior to, and ending on the second anniversary of, the effective time. The estimated amount of such payments is shown in the following table:

Material United States Federal Income Tax Consequences

The following is a summary of the material United States federal income tax consequences of the merger to U.S. holders (as defined below) of PrivateBancorp common stock and the ownership of CIBC common shares received in the merger. The below discussion applies to you only if you exchange your PrivateBancorp common stock for CIBC common shares in the merger and you hold your PrivateBancorp common stock and CIBC common shares as capital assets for tax purposes. This section does not apply to you if you are a member of a special class of holders subject to special rules, including:

•: a holder who acquired PrivateBancorp common stock pursuant to the exercise of employee stock options or otherwise as compensation,

Table of Contents

•: a dealer in securities,
•: a financial institution;
•: a dealer or broker in stocks and securities, or currencies,
•: a trader in securities that elects to use a mark-to-market method of accounting for securities holdings,
•: a tax-exempt organization,
•: an S corporation or other pass-through entity (or an investor in an S corporation or other pass-through entity),
•: a life insurance company,
•: a mutual fund,
•: a person liable for alternative minimum tax,
•: a person that actually or constructively owns 5% or more of the voting stock of PrivateBancorp or CIBC,
•: a person that holds shares of PrivateBancorp common stock or CIBC common shares as part of a straddle or a hedging or conversion transaction,
•: a U.S. holder (as defined below) whose functional currency is not the U.S. dollar, or
•: a United States expatriate.

This section is based on the Code, its legislative history, existing and proposed regulations, and published rulings and court decisions, all as currently in effect, as well as the Canada-United States Income Tax Convention (1980) as amended, referred to as the "Treaty." These laws are subject to change, possibly on a retroactive basis. We have not and will not seek any rulings from the United States Internal Revenue Service ("IRS") regarding the matters discussed below. There can be no assurance that the IRS will not take positions concerning the tax consequences of the merger that are different from those discussed below. In addition, the discussion does not address any alternative minimum tax or any state, local or non-U.S. tax consequences of the merger, nor does it address any tax consequences arising under the unearned income Medicare contribution tax pursuant to the Health Care and Education Reconciliation Act of 2010. Determining the actual tax consequences of the merger to you may be complex. They will depend on your specific situation and on factors that are not within the control of CIBC or PrivateBancorp. You should consult with your own tax advisor as to the tax consequences of the merger in your particular circumstances.

If a partnership holds CIBC common shares or PrivateBancorp common stock, the tax treatment of a partner will generally depend on the status of the partners and the tax treatment of the partnership. If you are a partner of a partnership holding CIBC common shares or PrivateBancorp common stock, you should consult your tax advisors.

For purposes of this discussion, we use the term "U.S. holder" to mean a beneficial owner of PrivateBancorp common stock or CIBC common shares, as relevant, that is:

•: an individual citizen or resident of the United States for United States federal income tax purposes,
•: a corporation (or other entity treated as a corporation for United States federal income tax purposes) created or organized in or under the laws of the United States, any U.S. state or the District of Columbia,

Table of Contents

•: an estate the income of which is subject to United States federal income taxation regardless of its source, or
•: a trust which either (1) is subject to the primary supervision of a court within the United States and one or more United States persons have the authority to control all substantial decisions of the trust or (2) has a valid election in effect under applicable United States Treasury regulations to be treated as a United States person.

The Merger

General Tax Consequences of the Merger

The merger is intended to qualify as a reorganization for United States federal income tax purposes, and it is a condition to the parties' respective obligations to complete the merger that each of CIBC and PrivateBancorp receive a legal opinion from Mayer Brown LLP and Wachtell, Lipton, Rosen & Katz, respectively, to the effect that (i) the merger will qualify as a "reorganization" within the meaning of Section 368(a) of the Code and (ii) the merger will not result in gain recognition to the holders of PrivateBancorp common stock pursuant to Section 367(a) of the Code (assuming that, in the case of any such holder who would be treated as a "five-percent transferee shareholder" within the meaning of Treasury Regulations Section 1.367(a)-3(c)(5)(ii), such holder enters into a five-year gain recognition agreement in the form provided in Treasury Regulations Section 1.367(a)-8, as provided for in Treasury Regulations Section 1.367(a)-3(c)(1)(iii)(B), and complies with the requirements of that agreement and Treasury Regulations Section 1.367(a)-8 for avoiding the recognition of gain). These opinions will be based on assumptions, representations, warranties and covenants, including those contained in the merger agreement and in tax representation letters, to be provided by CIBC and PrivateBancorp. The accuracy of such assumptions, representations and warranties, and compliance with such covenants, could affect the conclusions set forth in such opinions.

Provided the merger qualifies as a "reorganization" within the meaning of Section 368(a) of the Code, a PrivateBancorp common stockholder, upon exchanging the holder's PrivateBancorp common stock for CIBC common shares and cash (other than cash received in lieu of a fractional share),generally will recognize gain (but not loss) in an amount equal to the lesser of (i) the amount of gain realized (i.e., the excess of the sum of the amount of cash and the fair market value of the CIBC common shares received pursuant to the merger over that holder's adjusted tax basis in its shares of PrivateBancorp common stock surrendered) and (ii) the amount of cash received pursuant to the merger (excluding any cash received in lieu of a fractional share). If a holder acquired different blocks of PrivateBancorp common stock at different times or different prices, such holder should consult its tax advisor regarding the manner in which gain or loss should be determined. Any recognized gain generally will be long-term capital gain if, as of the effective date of the merger, the holder's holding period with respect to the PrivateBancorp common stock surrendered exceeds one year. If, however, the cash received has the effect of the distribution of a dividend, the gain will be treated as a dividend to the extent of the holder's ratable share of accumulated earnings and profits as calculated for United States federal income tax purposes. See "—Possible Treatment of Cash as a Dividend" below.

The aggregate tax basis in the shares of CIBC common shares that a PrivateBancorp common stockholder receives in the merger, including any fractional share interests deemed received and sold as described below, will equal the holder's aggregate adjusted tax basis in the PrivateBancorp common stock the holder surrenders, reduced by the amount of cash received (excluding any cash received in lieu of a fractional share) and increased by the amount of gain, if any recognized by the holder (excluding any gain recognized with respect to cash received in lieu of a fractional share) on the exchange. A PrivateBancorp common stockholder's holding period for the shares of CIBC common shares that the holder receives in the merger (including a fractional share interest deemed received and

Table of Contents

sold as described below) will include the holder's holding period for the shares of PrivateBancorp common stock that the holder surrenders in the exchange.

Possible Treatment of Cash as a Dividend

In general, the determination of whether the gain recognized in the exchange will be treated as capital gain or has the effect of a distribution of a dividend depends upon whether and to what extent the exchange reduces the holder's deemed percentage stock ownership of CIBC. For purposes of this determination, the holder is treated as if it first exchanged all of its shares of PrivateBancorp common stock solely for CIBC common shares and then CIBC immediately redeemed, which we refer to in this document as the "deemed redemption," a portion of the CIBC common shares in exchange for the cash the holder actually received. The gain recognized in the deemed redemption will be treated as capital gain if the deemed redemption is (i) "substantially disproportionate" with respect to the holder or (ii) "not essentially equivalent to a dividend."

The deemed redemption will generally be "substantially disproportionate" with respect to a holder if the percentage described in (ii) below is less than 80% of the percentage described in (i) below. Whether the deemed redemption is "not essentially equivalent to a dividend" with respect to a holder will depend upon the holder's particular circumstances. At a minimum, however, in order for the deemed redemption to be "not essentially equivalent to a dividend," the deemed redemption must result in a "meaningful reduction" in the holder's deemed percentage stock ownership of CIBC. In general, that determination requires a comparison of (i) the percentage of the outstanding stock of CIBC that the holder is deemed actually and constructively to have owned immediately before the deemed redemption and (ii) the percentage of the outstanding stock of CIBC that is actually and constructively owned by the holder immediately after the deemed redemption. In applying the above tests, a holder may, under the constructive ownership rules, be deemed to own stock that is owned by other persons or stock underlying a holder's option to purchase in addition to the stock actually owned by the holder.

The Internal Revenue Service has ruled that a shareholder in a publicly held corporation whose relative stock interest is minimal (e.g., less than 1%) and who exercises no control with respect to corporate affairs is generally considered to have a "meaningful reduction" if that shareholder has a relatively minor (e.g., approximately 3%) reduction in its percentage stock ownership under the above analysis; accordingly, the gain recognized in the exchange by such a shareholder would be treated as capital gain.

These rules are complex and dependent upon the specific factual circumstances particular to each holder. Consequently, each holder that may be subject to these rules should consult its tax advisor as to the application of these rules to the particular facts relevant to such holder.

Cash in Lieu of Fractional Shares

A U.S. holder of PrivateBancorp common stock who receives cash in lieu of a fractional share of CIBC common shares in the merger generally will be treated as having received such fractional share in the merger and then as having received cash in redemption of such fractional share. Gain or loss generally will be recognized based on the difference between the amount of cash received in lieu of the fractional share and the portion of the U.S. holder's aggregate tax basis in the PrivateBancorp common stock surrendered which is allocable to the fractional share. This gain or loss generally will be capital gain or loss, and long-term capital gain or loss if the holding period for the PrivateBancorp common stock is more than one year at the effective time of the merger. Long-term capital gain of non-corporate U.S. holders is generally taxed at preferential rates. The deductibility of capital losses is subject to limitations.

Backup Withholding and Information Reporting on the Merger

Payments of cash made to a U.S. holder and exchanges of shares by a U.S. holder for which gain or loss is recognized in connection with the merger may be subject to information reporting and, in the case of payments of cash, "backup withholding" unless the U.S. holder of PrivateBancorp common stock:

•: provides a correct taxpayer identification number and any other required information to the exchange agent, or
•: is a corporation or comes within certain exempt categories and otherwise complies with applicable requirements of the backup withholding rules.

Backup withholding does not constitute an additional tax, but merely an advance payment of tax, which may be refunded to the extent it results in an overpayment of tax if the required information is supplied to the IRS.

Ownership and Disposition of CIBC Common Shares by U.S. Holders

Passive Foreign Investment Company

CIBC does not believe that it is, for U.S. federal income tax purposes, a passive foreign investment company, or PFIC, and expects to operate in such a manner so as not to become a PFIC, but this conclusion is a factual determination that is made annually and thus may be subject to change. If CIBC is or becomes a PFIC, you could be subject to additional United States federal income taxes on gains recognized with respect to CIBC common shares and on certain distributions, plus an interest charge on certain taxes treated as having been deferred under the PFIC rules. The remainder of this discussion assumes that CIBC will not be treated as a PFIC for U.S. federal income tax purposes.

Taxation of Dividends to U.S. Holders

Distributions on a U.S. holder's CIBC common shares (including amounts withheld to reflect Canadian withholding taxes) will be taxable as dividends to the extent paid out of CIBC's current or accumulated earnings and profits, as determined under United States federal income tax principles. If you are a non-corporate U.S. holder, dividends paid to you that constitute qualified dividend income will be taxable to you at the preferential rates applicable to long-term capital gains provided that you meet certain holding period requirements. Dividends we pay with respect to CIBC common shares generally will be qualified dividend income.

A dividend is taxable to you when you receive the dividend, actually or constructively. The dividend will not be eligible for the dividends-received deduction generally allowed to U.S. corporations in respect of dividends received from other United States corporations. The amount of the dividend distribution that you must include in your income as a U.S. holder will be the U.S. dollar value of payments made (including amounts withheld to reflect Canadian withholding taxes). The U.S. dollar value of any Canadian dollar payments made will be determined at the spot Canadian dollar/U.S. dollar rate on the date the dividend distribution is includible in your income, regardless of whether the payment is in fact converted into U.S. dollars. Generally, any gain or loss resulting from currency exchange fluctuations during the period from the date you include the dividend payment in income to the date you convert the payment into U.S. dollars will be treated as ordinary income or loss and will not be eligible for the special tax rate applicable to qualified dividend income. The gain or loss generally will be income or loss from sources within the United States for foreign tax credit limitation purposes. Distributions in excess of current and accumulated earnings and profits, as determined for United States federal income tax purposes, will be treated as a non-taxable return of capital to the extent of your tax basis in your CIBC common shares and thereafter as capital gain.

Table of Contents

Subject to certain limitations, the Canadian tax withheld in accordance with the Treaty and paid over to Canada will be creditable or deductible against your United States federal income tax liability. Special rules apply in determining the foreign tax credit limitation with respect to dividends that are subject to the preferential tax rates. To the extent a refund of the tax withheld is available to you under Canadian law or under the Treaty, the amount of tax withheld that is refundable will not be eligible for credit against your U.S. federal income tax liability.

For foreign tax credit purposes, dividends will generally be income from sources outside the United States and will, depending on your circumstances, be either "passive" or "general" income for purposes of computing the foreign tax credit allowable to you.

Taxation of Dividends to Non-U.S. Holders

If you are a non-U.S. holder, dividends paid to you in respect of CIBC common shares will not be subject to United States federal income tax unless the dividends are "effectively connected" with your conduct of a trade or business within the United States, and the dividends are attributable to a permanent establishment that you maintain in the United States if that is required by an applicable income tax treaty as a condition for subjecting you to U.S. taxation on a net income basis. In such cases you generally will be taxed in the same manner as a U.S. holder. If you are a corporate non-U.S. holder, "effectively connected" dividends may, under certain circumstances, be subject to an additional "branch profits tax" at a 30% rate or at a lower rate if you are eligible for the benefits of an income tax treaty that provides for a lower rate.

Taxation of Capital Gains to U.S. Holders

If you are a U.S. holder and you sell or otherwise dispose of your CIBC common shares, you will recognize capital gain or loss for United States federal income tax purposes equal to the difference between the U.S. dollar value of the amount that you realize and your tax basis, determined in U.S. dollars, in your shares. Capital gain of a non-corporate U.S. holder is generally taxed at preferential rates where the property is held for more than one year. The gain or loss will generally be income or loss from sources within the United States for foreign tax credit limitation purposes.

Taxation of Capital Gains to Non-U.S. Holders

If you are a non-U.S. holder, you will not be subject to U.S. federal income tax on gain recognized on the sale or other disposition of your CIBC common shares unless (i) the gain is "effectively connected" with your conduct of a trade or business in the United States, and the gain is attributable to a permanent establishment that you maintain in the United States if that is required by an applicable income tax treaty as a condition for subjecting you to U.S. taxation on a net income basis, or (ii) you are an individual, you are present in the United States for 183 or more days in the taxable year of the sale and certain other conditions exist. If you are a corporate non-U.S. holder, "effectively connected" gains that you recognize may also, under certain circumstances, be subject to an additional "branch profits tax" at a 30% rate or at a lower rate if you are eligible for the benefits of an income tax treaty that provides for a lower rate.

Backup Withholding and Information Reporting

If you are a non-corporate U.S. holder, information reporting requirements, on IRS Form 1099, generally will apply to:

•: dividend payments or other taxable distributions made to you within the United States, and
•: the payment of proceeds to you from the sale of CIBC common shares effected at a U.S. office of a broker.

Table of Contents

Additionally, backup withholding may apply to such payments if you are a non-corporate U.S. holder that:

•: fails to provide an accurate taxpayer identification number,
•: is notified by the IRS that you have failed to report all interest and dividends required to be shown on your federal income tax returns, or
•: in certain circumstances, fails to comply with applicable certification requirements.

If you are a non-U.S. holder, you are generally exempt from backup withholding and information reporting requirements with respect to:

•: dividend payments made to you outside the United States by us or another non-U.S. payor,
•: other dividend payments and the payment of the proceeds from the sale of CIBC common shares effected at a U.S. office of a broker, as long as the income associated with such payments is otherwise exempt from United States federal income tax, and
•: the payor or broker does not have actual knowledge or reason to know that you are a U.S. person and you have furnished the payor or broker:
•: an IRS Form W-8BEN or W-8BEN-E or an acceptable substitute form upon which you certify, under penalties of perjury, that you are a non-United States person,
•: other documentation upon which it may rely to treat the payments as made to a non-United States person in accordance with U.S. Treasury regulations, or
•: you otherwise establish an exemption.

Payment of the proceeds from the sale of CIBC common shares effected at a foreign office of a broker generally will not be subject to information reporting or backup withholding. However, a sale of CIBC common shares or that is effected at a foreign office of a broker will be subject to information reporting and backup withholding if:

•: the proceeds are transferred to an account maintained by you in the United States,
•: the payment of proceeds or the confirmation of the sale is mailed to you at a U.S. address, or
•: the sale has some other specified connection with the United States as provided in U.S. Treasury regulations,

unless the broker does not have actual knowledge or reason to know that you are a United States person and the documentation requirements described above are met or you otherwise establish an exemption.

In addition, a sale of CIBC common shares effected at a foreign office of a broker will be subject to information reporting if the broker is:

•: a U.S. person,
•: a controlled foreign corporation for U.S. tax purposes,
•: a foreign person 50% or more of whose gross income is effectively connected with the conduct of a U.S. trade or business for a specified three-year period, or
•: a foreign partnership, if at any time during its tax year:
•: one or more of its partners are "U.S. persons," as defined in U.S. Treasury regulations, who in the aggregate hold more than 50% of the income or capital interest in the partnership, or

Table of Contents

•: such foreign partnership is engaged in the conduct of a U.S. trade or business, unless the broker does not have actual knowledge or reason to know that you are a United States person and the documentation requirements described above are met or you otherwise establish an exemption. Backup withholding will apply if the sale is subject to information reporting and the broker has actual knowledge that you are a U.S. person.

You generally may obtain a refund of any amounts withheld under the backup withholding rules that exceed your income tax liability by filing a refund claim with the IRS.

Information with Respect to Foreign Financial Assets

Owners of "specified foreign financial assets" with an aggregate value in excess of $50,000 (and in some circumstances a higher threshold) may be required to file an information report with respect to such assets with their tax returns. "Specified foreign financial assets" may include financial accounts maintained by foreign financial institutions, as well as any of the following, but only if they are not held in accounts maintained by financial institutions: (i) stocks and securities issued by non-U.S. persons, (ii) financial instruments and contracts held for investment that have non-U.S. issuers or counterparties, and (iii) interests in foreign entities. Holders are urged to consult their tax advisors regarding the application of this reporting requirement to their ownership of the CIBC common shares.

Foreign Account Tax Compliance Withholding

Pursuant to an intergovernmental agreements with the United States, CIBC and other non-U.S. financial institutions may be required to report information to our local governments regarding the holders of CIBC common shares (with subsequent transmission of that information by the local government to the IRS). In the future we may be required to withhold on a portion of dividend payments to holders of CIBC common shares if the indirect holders of those shares fail to comply with certain information reporting requirements. However, such withholding will not apply to payments made before the later of January 1, 2019 or the date on which final regulations are issued. The rules for implementation of this withholding have not yet been fully finalized, so it is impossible to determine at this time what impact, if any, such rules will have on holders of CIBC common shares.

This discussion does not address tax consequences that may vary with, or are contingent on, individual circumstances. Moreover, it only addresses U.S. federal income tax and does not address any non-income tax or any foreign, state or local tax consequences. You should consult your own tax advisors concerning the U.S. federal income tax consequences of the merger and the ownership of CIBC common shares in light of your particular situation, as well as any consequences arising under the laws of any other taxing jurisdiction.

Certain Canadian Federal Income Tax Consequences

The following summary describes the principal Canadian federal income tax considerations under the Income Tax Act (Canada) and the Income Tax Regulations, or collectively, the "Canadian Tax Act," of the disposition of PrivateBancorp common stock pursuant to the merger and the ownership of CIBC common shares received in consideration for the disposition of PrivateBancorp common stock pursuant to the merger, generally applicable to a beneficial owner of PrivateBancorp common stock who, for purposes of the Canadian Tax Act and at all relevant times, (1) is not and is not deemed to be resident in Canada; (2) deals at arm's length with CIBC and Holdco; (3) is not affiliated with CIBC and Holdco; (4) holds shares of PrivateBancorp common stock and CIBC common shares as capital property; and (5) does not use or hold, and is not deemed to use or hold, PrivateBancorp common stock or CIBC common shares in a business carried on in Canada, referred to as a "non-resident holder." Special rules, which are not discussed in this summary, may apply to certain holders that are insurers carrying on an insurance business in Canada and elsewhere.

Table of Contents

Generally, PrivateBancorp common stock and CIBC common shares will be capital property to a non-resident holder provided the non-resident holder does not hold those shares in the course of carrying on a business or as part of an adventure or concern in the nature of trade.

This summary is based on the current provisions of the Canadian Tax Act and CIBC's understanding of the current administrative policies and assessing practices of the Canada Revenue Agency published in writing prior to the date hereof. This summary takes into account all specific proposals to amend the Canadian Tax Act publicly announced by or on behalf of the Minister of Finance (Canada) prior to the date hereof, referred to as the "Proposed Amendments," and assumes that all Proposed Amendments will be enacted in the form proposed. However, no assurances can be given that the Proposed Amendments will be enacted as proposed, or at all. This summary does not otherwise take into account or anticipate any changes in law or administrative policy or assessing practice whether by legislative, administrative or judicial action nor does it take into account tax legislation or considerations of any province, territory or foreign jurisdiction, which may differ from those discussed herein.

This discussion does not address tax consequences that may vary with, or are contingent on, individual circumstances. This summary is not exhaustive of all Canadian federal income tax considerations. You should consult your own tax advisors concerning the Canadian federal income tax consequences of the merger and the ownership of CIBC common shares in light of your particular situation, as well as any consequences arising under the laws of any other taxing jurisdiction.

For the purposes of the Canadian Tax Act, any amount relating to the acquisition, holding or disposition of CIBC common shares must generally be converted into Canadian dollars using the noon exchange rate quoted by the Bank of Canada for the day on which the amount arose.

Disposition of PrivateBancorp Common Stock Pursuant to the Merger

A non-resident holder will not be subject to tax under the Canadian Tax Act on any capital gain realized on the disposition of PrivateBancorp common stock pursuant to the merger, unless the PrivateBancorp common stock is "taxable Canadian property" to the non-resident holder for purposes of the Canadian Tax Act at the time of the disposition and the non-resident holder is not entitled to relief under an applicable income tax convention between Canada and the country in which the non-resident holder is resident. See the section below entitled "Taxable Canadian Property."

Dividends on CIBC Common Shares

Dividends paid or credited or deemed to be paid or credited on the CIBC common shares to a non-resident holder will be subject to Canadian withholding tax at the rate of 25%, subject to any reduction in the rate of withholding to which the non-resident holder is entitled under any applicable income tax convention. Under the Canada-U.S. Income Tax Convention (1980), referred to as the "Treaty," where dividends on the CIBC common shares are considered to be paid to or derived by a non-resident holder that is the beneficial owner of the dividends and is a U.S. resident for the purposes of, and is entitled to benefits in accordance with, the provisions of the Treaty, the applicable rate of Canadian withholding tax is generally reduced to 15%.

Disposition of CIBC Common Shares

A non-resident holder will not be subject to tax under the Canadian Tax Act on any capital gain realized on a disposition or deemed disposition of CIBC common shares, unless the CIBC common shares are "taxable Canadian property" to the non-resident holder for purposes of the Canadian Tax Act at the time of the disposition and the non-resident holder is not entitled to relief under an applicable income tax convention between Canada and the country in which the non-resident holder is resident. See the section below entitled "Taxable Canadian Property."

Table of Contents

Taxable Canadian Property

Generally, PrivateBancorp common stock or CIBC common shares, as the case may be, will not constitute taxable Canadian property to a non-resident holder at a particular time provided that the applicable shares are listed at that time on a designated stock exchange (which includes the NYSE, the NASDAQ and the TSX), unless at any particular time during the 60-month period that ends at that time (1) one or any combination of (i) the non-resident holder, (ii) persons with whom the non-resident holder does not deal at arm's length, and (iii) partnerships in which the non-resident holder or a person described in (ii) holds a membership interest directly or indirectly through one or more partnerships, owned 25% or more of the issued shares of any class or series of the capital stock of PrivateBancorp or CIBC, as the case may be, and (2) more than 50% of the fair market value of the PrivateBancorp common stock or CIBC common shares, as the case may be, was derived directly or indirectly from one or any combination of: (i) real or immovable properties situated in Canada, (ii) "Canadian resource properties" (as defined in the Canadian Tax Act), (iii) "timber resource properties" (as defined in the Canadian Tax Act), and (iv) options in respect of, or interests in, or for civil law rights in, any of the foregoing property whether or not the property exists. Notwithstanding the foregoing, in certain circumstances set out in the Canadian Tax Act, PrivateBancorp common stock or CIBC common shares, as the case may be, could be deemed to be taxable Canadian property to a particular non-resident holder. Non-resident holders whose PrivateBancorp common stock or CIBC common shares may constitute taxable Canadian property should consult their own tax advisors.

Even if PrivateBancorp common stock or CIBC common shares are taxable Canadian property to a non-resident holder, the Treaty will generally exempt a non-resident holder that is a U.S. resident for the purposes of, and is entitled to benefits in accordance with, the provisions of the Treaty from tax under the Canadian Tax Act on any capital gain arising on the disposition of PrivateBancorp common stock or CIBC common shares, as the case may be, unless the value of the PrivateBancorp common stock or CIBC common shares, as the case may be, at the time of disposition is derived principally from real property situated in Canada.

Accounting Treatment

The merger will be accounted for by CIBC as a business combination applying the acquisition method of accounting for IFRS purposes. Accordingly, the aggregate fair value of the consideration paid by CIBC in connection with the merger will be allocated to PrivateBancorp's net assets based on their fair values as of the close of the transaction. The excess of the total purchase consideration over the fair value of the identifiable assets acquired, liabilities assumed and any non-controlling interest in PrivateBancorp will be allocated to goodwill. The results of operations of PrivateBancorp will be included in CIBC's consolidated results of operations only for periods subsequent to the completion of the merger.

Stock Exchange Listings

CIBC common shares are currently listed on the TSX and the NYSE. The CIBC common shares to be issued in connection with the merger will be listed on the TSX and the NYSE upon completion of the merger. Shares of PrivateBancorp common stock will be delisted from the NASDAQ promptly following completion of the merger.

Regulatory Matters Related to the Merger

Completion of the merger is subject to the receipt of all required regulatory approvals from the Federal Reserve Board, the Superintendent of Financial Institutions (Canada) and the Illinois Department, the receipt of all other required approvals or consents, including those the failure of which to obtain would reasonably be expected to have a material adverse effect on CIBC or

Table of Contents

PrivateBancorp, and the expiration of any applicable statutory waiting period. CIBC and PrivateBancorp have agreed to use their reasonable best efforts to obtain all the required regulatory approvals. We have made such filings for approvals with the Federal Reserve Board, the Superintendent of Financial Institutions (Canada) and the Illinois Department.

We believe that we will be able to obtain all required regulatory approvals on a timely basis. However, we cannot make any assurances as to whether or when the required regulatory approvals will be obtained, or whether any such approval will contain any materially burdensome condition. If any material regulatory approval imposes a materially burdensome condition, the parties will not be required to complete the merger. The approval of an application means only that the regulatory criteria for approval have been satisfied or waived. It does not mean that the approving authority has determined that the consideration to be received by PrivateBancorp common stockholders in the merger is fair. Regulatory approval does not constitute an endorsement or recommendation of the merger.

Federal Reserve Board Approval

Completion of the merger is subject, among other things, to approval by the Federal Reserve Board pursuant to Section 3 of the Bank Holding Company Act of 1956, as amended, referred to as the "BHC Act."

The Federal Reserve Board may not grant that approval if it determines that the merger:

•: would result in a monopoly or be in furtherance of any combination or conspiracy to monopolize or to attempt to monopolize the business of banking in any part of the United States; or
•: would substantially lessen competition in any part of the United States, or tend to create a monopoly or result in a restraint of trade,

unless the Federal Reserve Board finds that the anti-competitive effects of the merger are clearly outweighed in the public interest by the probable effect of the merger in meeting the convenience and needs of the communities to be served.

Additionally, the Federal Reserve Board may not grant approval if it determines that CIBC is not subject to comprehensive supervision or regulation on a consolidated basis by the appropriate authorities in Canada, or if CIBC does not provide the Federal Reserve Board with adequate assurances that CIBC will make information available to the Federal Reserve Board as appropriate to determine compliance with applicable banking laws and regulations.

In reviewing the merger, the Federal Reserve Board will consider, among other things:

•: the financial and managerial resources of both companies and PrivateBank both currently and after giving effect to the merger;
•: the capital adequacy of CIBC after the merger;
•: the convenience and needs of the communities to be served;
•: applicable overall capital and safety and soundness standards;
•: the effectiveness of both companies in combating money laundering activities;
•: each company's regulatory status, including legal and regulatory compliance; and
•: the extent to which the proposed acquisition would result in greater or more concentrated risks to the stability of the United States banking or financial system.

Table of Contents

Under the Community Reinvestment Act of 1977, as amended, referred to as the "CRA," the Federal Reserve Board will take into account PrivateBancorp's records of performance in meeting the credit needs of its communities, including low-and moderate-income neighborhoods. PrivateBancorp has one insured depository institution subsidiary required to have ratings under the CRA and such institution has received a satisfactory CRA rating in its most recent CRA examinations by its federal regulators.

Furthermore, the BHC Act and Federal Reserve Board regulations require published notice of, and the opportunity for public comment on, our application, and authorize the Federal Reserve Board to hold a public hearing or meeting if the Federal Reserve Board determines that a hearing or meeting would be appropriate. Any hearing or meeting or comments provided by third parties could prolong the period during which the application is under review by the Federal Reserve Board.

The BHC Act requires a waiting period of 30 days after Federal Reserve Board approval is received before the merger may be completed, during which time the DOJ may challenge the merger on antitrust grounds. With the approval of the Federal Reserve Board and the concurrence of the DOJ, such waiting period may be reduced to no less than 15 days. The commencement of an antitrust action would stay the effectiveness of such an approval unless a court specifically ordered otherwise. In reviewing the merger, the DOJ could analyze the merger's effect on competition differently than the Federal Reserve Board, and thus it is possible that the DOJ could reach a different conclusion than the Federal Reserve Board does regarding the merger's effects on competition. A determination by the DOJ not to object to the merger may not prevent the filing of antitrust actions by private persons or state attorneys general.

If Federal Reserve approval is obtained and the merger is completed, then CIBC and CIBC Holdco will each become a bank holding company under the BHC Act. CIBC is a foreign banking organization that is already treated as a bank holding company under the BHC Act. Generally, the operations of a foreign banking organization and its U.S. subsidiaries and offices are subject to the same comprehensive regulatory regime that governs the operations of U.S. domestic banking organizations, although there are certain differences. If the merger is completed, CIBC Holdco will become subject to supervision and regulation by the Federal Reserve as a domestic U.S. bank holding company. CIBC will also continue to be subject to supervision and regulation by the Federal Reserve, and would be required to comply with certain additional requirements under the BHC Act and Federal Reserve regulations.

Illinois Department Approval

Completion of the merger is subject, among other things, to approval by the Secretary of the Illinois Department (the "Commissioner") under the Illinois BHC Act and Illinois Banking Act.

To approve the merger, the Commissioner must make certain findings, including among others that:

•: the general character of the proposed management is such as to assure reasonable promise of successful, safe and sound operation;
•: depositors' interest will not be jeopardized;
•: future earnings prospects of CIBC after the merger are favorable;
•: any prior involvement of CIBC or proposed management personnel with any other financial institution, whether as stockholder, director, officer or customer, was conducted in a safe and sound manner; and
•: the acquisition is authorized under the Illinois BHC Act.

Table of Contents

The Commissioner also shall not approve the merger if upon consummation of the transaction CIBC and its affiliates would control 30% or more of the total amount of deposits which are located in Illinois at insured depository institutions.

CIBC is required to effect change in control within 180 days of Commissioner's approval of the merger and to notify the Commissioner of the date when the change in control is finally effected.

Canadian Approvals

Under the Bank Act, the approval of the Superintendent of Financial Institutions (Canada) is required in order for CIBC to complete the acquisition.

Holdco is a permitted investment under paragraph 468(2)(b) of the Bank Act. Under the Bank Act, CIBC will be considered to have acquired an indirect beneficial interest in each of the subsidiaries of PrivateBancorp upon the merger of PrivateBancorp with and into Holdco. As a result, the approval of the Superintendent of Financial Institutions (Canada) is required in respect of PrivateBank, since it is an entity referred to in paragraph 468(1)(j) of the Bank Act, which requires approval pursuant to Section 468(6) of the Bank Act.

Under subsection 65(1) of the Bank Act, no share of any class of shares of a bank shall be issued until it is fully paid for in money or, with the approval of the Superintendent of Financial Institutions (Canada), in property. Pursuant to the merger agreement, if the merger is completed, holders of PrivateBancorp common stock will have the right to receive the merger consideration for each share of PrivateBancorp common stock held immediately prior to the merger. The consideration for the issuance by CIBC of its common shares as part of the merger consideration will be shares of PrivateBancorp. As a result, approval of the Superintendent of Financial Institutions (Canada) is required for CIBC to issue common shares in consideration for shares of PrivateBancorp.

Other Regulatory Filings

Applications and notifications will be filed with other regulatory authorities, including the Delaware Secretary pursuant to Delaware law.

Dissenters' Rights of Appraisal for Holders of PrivateBancorp Common Stock

The following discussion summarizes certain terms of the law pertaining to appraisal rights under Delaware law and is qualified in its entirety by the full text of Section 262 of Delaware law, referred to as "Section 262," which Section 262 (in effect as of the date of this proxy statement/prospectus) is attached to this document as Appendix D. The following summary does not constitute legal or other advice, nor does it constitute a recommendation that stockholders exercise their appraisal rights under Section 262.

Under Section 262, record holders of shares of PrivateBancorp's common stock who have neither voted in favor of, nor consented in writing to, the adoption of the merger agreement, who continuously hold such shares through the effective time of the merger and who otherwise follow the procedures set forth in Section 262 will be entitled to have their shares appraised by the Delaware Court of Chancery and to receive payment in cash of the "fair value" of the shares, exclusive of any element of value arising from the accomplishment or expectation of the merger, as determined by the Court, together with interest, if any, to be paid upon the amount determined to be the fair value.

Under Section 262, where a merger agreement relating to a proposed merger is to be submitted for approval at a meeting of stockholders, the corporation, not less than 20 days prior to the meeting, must notify each of its stockholders who was a stockholder on the record date set by the board of directors for such notice (or if no such record date is set, on the close of business on the day next preceding the day on which notice is given), with respect to such shares for which appraisal rights are

Table of Contents

available, that appraisal rights are so available, and must include in each such notice a copy of Section 262. This document constitutes such notice to the holders of PrivateBancorp's common stock and a copy of Section 262 (in effect as of the date of this proxy statement/prospectus) is attached to this document as Appendix D.

ANY HOLDER OF PRIVATEBANCORP'S COMMON STOCK WHO WISHES TO EXERCISE APPRAISAL RIGHTS, OR WHO WISHES TO PRESERVE SUCH HOLDER'S RIGHT TO DO SO, SHOULD CAREFULLY REVIEW THE FOLLOWING DISCUSSION AND APPENDIX D BECAUSE FAILURE TO TIMELY AND PROPERLY COMPLY WITH THE PROCEDURES SPECIFIED WILL RESULT IN THE LOSS OF APPRAISAL RIGHTS. MOREOVER, BECAUSE OF THE COMPLEXITY OF THE PROCEDURES FOR EXERCISING THE RIGHT TO SEEK APPRAISAL OF SHARES OF PRIVATEBANCORP COMMON STOCK, PRIVATEBANCORP BELIEVES THAT, IF A STOCKHOLDER CONSIDERS EXERCISING SUCH RIGHTS, SUCH STOCKHOLDER SHOULD SEEK THE ADVICE OF LEGAL COUNSEL.

Filing Written Demand

Holders of shares of PrivateBancorp's common stock who decide to exercise their appraisal rights must make a demand, in writing, for appraisal of their shares of common stock prior to the taking of the vote on the merger at the stockholders meeting. A demand for appraisal will be sufficient if it reasonably informs PrivateBancorp of the identity of the stockholder and that such stockholder intends thereby to demand appraisal of such stockholder's shares of common stock. If you wish to exercise your appraisal rights you must be the record holder of such shares of PrivateBancorp's common stock on the date the written demand for appraisal is made and you must continue to hold such shares through the closing of the merger. Accordingly, a stockholder who is the record holder of shares of common stock on the date the written demand for appraisal is made, but who thereafter transfers such shares prior to the closing of the merger, will lose any right to appraisal in respect of such shares. A stockholder's failure to make the written demand prior to the taking of the vote on the merger will constitute a waiver of appraisal rights.

Only a holder of record of shares of PrivateBancorp's common stock is entitled to demand an appraisal of the shares registered in that holder's name. A demand for appraisal in respect of shares of capital stock should be executed by or on behalf of the holder of record, fully and correctly, as the holder's name appears on the holder's stock certificates, should specify the holder's name and mailing address and the number of shares registered in the holder's name and must state that the person intends thereby to demand appraisal of the holder's shares in connection with the merger. If the shares are owned of record in a fiduciary capacity, such as by a trustee, guardian or custodian, execution of the demand should be made in that capacity, and if the shares are owned of record by more than one person, as in a joint tenancy and tenancy in common, the demand should be executed by or on behalf of all joint owners. An authorized agent, including an agent for two or more joint owners, may execute a demand for appraisal on behalf of a holder of record; however, the agent must identify the record owner or owners and expressly disclose that, in executing the demand, the agent is acting as agent for the record owner or owners. If the shares are held in "street name" by a broker, bank or nominee, the broker, bank or nominee may exercise appraisal rights with respect to the shares held for one or more beneficial owners while not exercising the rights with respect to the shares held for other beneficial owners; in such case, however, the written demand should set forth the number of shares as to which appraisal is sought and where no number of shares is expressly mentioned the demand will be presumed to cover all shares of capital stock held in the name of the record owner. If a stockholder holds shares of PrivateBancorp common stock through a broker who in turn holds the shares through a central securities depository nominee such as Cede & Co., a demand for appraisal of such shares must be made by or on behalf of the depository nominee and must identify the depository nominee as record holder. Stockholders who hold their shares in brokerage accounts or other nominee forms and who

100

Table of Contents

wish to exercise appraisal rights should consult with their brokers to determine the appropriate procedures for the making of a demand for appraisal by such a nominee.

All written demands for appraisal pursuant to Section 262 should be sent or delivered to PrivateBancorp at:

PrivateBancorp, Inc.
120 South LaSalle Street
Chicago, Illinois 60603
Attention: Corporate Secretary

At any time within 60 days after the effective date of the merger, any stockholder who has not commenced an appraisal proceeding or joined that proceeding as a named party may withdraw his, her or its demand for appraisal and accept the consideration offered pursuant to the merger agreement by delivering to CIBC, a written withdrawal of the demand for appraisal. However, any such attempt to withdraw the demand made more than 60 days after the effective date of the merger will require written approval of CIBC. No appraisal proceeding in the Delaware Court of Chancery will be dismissed as to any stockholder without the approval of the Delaware Court of Chancery, and such approval may be conditioned upon such terms as the Court deems just; provided, however, that any stockholder who has not commenced an appraisal proceeding or joined that proceeding as a named party may withdraw his, her or its demand for appraisal and accept the merger consideration offered pursuant to the merger agreement within 60 days after the effective date of the merger. If CIBC does not approve a request to withdraw a demand for appraisal when that approval is required, or, except with respect to any stockholder who withdraws such stockholder's demand in accordance with the proviso in the immediately preceding sentence, if the Delaware Court of Chancery does not approve the dismissal of an appraisal proceeding with respect to a stockholder, the stockholder will be entitled to receive only the appraised value determined in any such appraisal proceeding, which value could be less than, equal to or more than the consideration being offered pursuant to the merger agreement.

From and after the effective date of the merger, any stockholder who has duly demanded appraisal in compliance with Section 262 will not be entitled to vote for any purpose the shares of common stock subject to appraisal or to receive payment of dividends or other distributions on such shares except for dividends or distributions payable to stockholders of record at a date prior to the effective date of the merger.

Notice of the Effective Date

Within 10 days after the effective date of the merger, CIBC must notify each holder of PrivateBancorp's common stock entitled to appraisal rights of the effective date of the merger. Such notice may also be given by CIBC to each holder of PrivateBancorp's common stock who is entitled to appraisal rights before the effective date of the merger.

Filing a Petition for Appraisal

Within 120 days after the effective date of the merger, but not thereafter, CIBC or any holder of PrivateBancorp's common stock who has complied with Section 262 and is entitled to appraisal rights under Section 262 may commence an appraisal proceeding by filing a petition in the Delaware Court of Chancery demanding a determination of the fair value of the shares held by all dissenting holders. CIBC is under no obligation to and has no present intention to file a petition and holders should not assume that CIBC will file a petition. Accordingly, it is the obligation of the holders of capital stock to initiate all necessary action to perfect their appraisal rights in respect of shares of capital stock within the time prescribed in Section 262. Within 120 days after the effective date of the merger, any holder of capital stock who has complied with the requirements for exercise of appraisal rights will be entitled, upon written request, to receive from CIBC a statement setting forth the aggregate number of shares

101

Table of Contents

not voted in favor of the approval of the merger agreement and with respect to which demands for appraisal have been received and the aggregate number of holders of such shares. The statement must be mailed within ten days after a written request therefor has been received by CIBC or within ten days after the expiration of the period for delivery of demands for appraisal, whichever is later. Notwithstanding the foregoing, a person who is the beneficial owner of shares of capital stock held either in a voting trust or by a nominee on behalf of such person may, in such person's own name, file a petition or request to receive from CIBC the statement described in this paragraph.

If a petition for an appraisal is timely filed by a holder of shares of PrivateBancorp's common stock and a copy thereof is served upon CIBC, CIBC will then be obligated within 20 days to file with the Delaware Register in Chancery a duly verified list containing the names and addresses of all stockholders who have demanded an appraisal of their shares and with whom agreements as to the value of their shares have not been reached. After notice to the stockholders as required by the Court, the Delaware Court of Chancery is empowered to conduct a hearing on the petition to determine those stockholders who have complied with Section 262 and who have become entitled to appraisal rights thereunder. The Delaware Court of Chancery may require the stockholders who demanded payment for their shares to submit their stock certificates to the Register in Chancery for notation thereon of the pendency of the appraisal proceeding; and if any stockholder fails to comply with the direction, the Delaware Court of Chancery may dismiss the proceedings as to the stockholder. The Delaware Court of Chancery shall dismiss the proceedings unless (i) the total number of shares entitled to appraisal exceeds 1% of the outstanding common stock eligible for appraisal or (ii) the value of the consideration provided in the merger for such total number of common stock exceeds $1 million.

Determination of Fair Value

After the Delaware Court of Chancery determines the holders of capital stock entitled to appraisal, the appraisal proceeding shall be conducted in accordance with the rules of the Delaware Court of Chancery, including any rules specifically governing appraisal proceedings. Through such proceeding, the Court shall determine the "fair value" of the shares, exclusive of any element of value arising from the accomplishment or expectation of the merger, together with interest, if any, to be paid upon the amount determined to be the fair value. Unless the Court in its discretion determines otherwise for good cause shown, and except as provided below, interest from the effective date of the merger through the date of payment of the judgment shall be compounded quarterly and shall accrue at five percent over the Federal Reserve discount rate (including any surcharge) as established from time to time during the period between the effective date of the merger and the date of payment of the judgment. At any time before the entry of judgment in the proceedings, the Holdco may pay to each stockholder entitled to appraisal an amount in cash, in which case interest shall accrue thereafter as provided herein only upon the sum of (i) the difference, if any, between the amount so paid and the fair market value of the shares as determined by the Delaware Court of Chancery, and (ii) interest theretofore accrued, unless paid at the time.

In determining fair value, the Delaware Court of Chancery will take into account all relevant factors. In Weinberger v. UOP, Inc., the Supreme Court of Delaware discussed the factors that could be considered in determining fair value in an appraisal proceeding, stating that "proof of value by any techniques or methods that are generally considered acceptable in the financial community and otherwise admissible in court" should be considered, and that "fair price obviously requires consideration of all relevant factors involving the value of a company." The Delaware Supreme Court stated that, in making this determination of fair value, the court must consider market value, asset value, dividends, earnings prospects, the nature of the enterprise and any other facts that could be ascertained as of the date of the merger that throw any light on future prospects of the merged corporation. Section 262 provides that fair value is to be "exclusive of any element of value arising from the accomplishment or expectation of the merger." In Cede & Co. v. Technicolor, Inc., the

102

Table of Contents

Delaware Supreme Court stated that such exclusion is a "narrow exclusion that does not encompass known elements of value," but which rather applies only to the speculative elements of value arising from such accomplishment or expectation. In Weinberger, the Supreme Court of Delaware also stated that "elements of future value, including the nature of the enterprise, which are known or susceptible of proof as of the date of the merger and not the product of speculation, may be considered."

Stockholders considering seeking appraisal should be aware that the fair value of their shares as so determined may be more than, the same as or less than the consideration they would receive pursuant to the merger if they did not seek appraisal of their shares and that an investment banking opinion as to the fairness, from a financial point of view, of the consideration payable in a sale transaction, such as the merger, is not an opinion as to, and does not otherwise address, fair value under Section 262. Although PrivateBancorp believes that the merger consideration is fair, no representation is made as to the outcome of the appraisal of fair value as determined by the Delaware Court of Chancery, and stockholders should recognize that such an appraisal could result in a determination of a value higher or lower than, or the same as, the merger consideration. Neither CIBC nor PrivateBancorp anticipates offering more than the applicable merger consideration to any stockholder of PrivateBancorp exercising appraisal rights, and each of CIBC and PrivateBancorp reserves the right to assert, in any appraisal proceeding, that for purposes of Section 262, the "fair value" of a share of capital stock is less than the applicable merger consideration.

If a petition for appraisal is not timely filed, then the right to an appraisal will cease. The costs of the action (which do not include attorneys' fees or the fees and expenses of experts) may be determined by the Court and taxed upon the parties as the Court deems equitable under the circumstances. Upon application of a stockholder, the Court may order all or a portion of the expenses incurred by a stockholder in connection with an appraisal proceeding, including, without limitation, reasonable attorneys' fees and the fees and expenses of experts utilized in the appraisal proceeding, to be charged pro rata against the value of all the shares entitled to be appraised.

If any stockholder who demands appraisal of shares of capital stock under Section 262 fails to perfect, successfully withdraws or loses such holder's right to appraisal, the stockholder's shares of capital stock will be deemed to have been converted at the effective date of the merger into the right to receive the merger consideration pursuant to the merger agreement. A stockholder will fail to perfect, or effectively lose, the stockholder's right to appraisal if no petition for appraisal is filed within 120 days after the effective date of the merger. In addition, as indicated above, a stockholder may withdraw his, her or its demand for appraisal in accordance with Section 262 and accept the merger consideration offered pursuant to the merger agreement.

Resale of CIBC Common Shares

U.S. Resale Restrictions

The CIBC common shares issued under the terms of the merger agreement will not be subject to any restrictions on transfer arising under the Securities Act of 1933, as amended, referred to as the "Securities Act."

Canadian Resale Restrictions

The CIBC common shares issued under the terms of the merger agreement will not be subject to any restrictions on transfer under applicable Canadian provincial or territorial securities laws. To the extent Canadian provincial or territorial securities laws apply, however, the first trade in the CIBC common shares issued under the terms of the merger agreement must be made in accordance with customary conditions, including that such trade is not a control distribution, that no unusual effort is made to prepare the market or to create a demand for such shares and that no extraordinary commission or consideration is paid in respect of the trade. In addition, when selling the CIBC

103

Table of Contents

common shares, holders who engage in the business of trading in securities, or hold themselves out as engaging in the business of trading in securities may also be subject to dealer registration requirements of applicable Canadian provincial or territorial securities laws. If a holder requires advice on the application of Canadian provincial or territorial securities laws to the trade of CIBC common shares, the holder should consult its own legal advisor.

Litigation Related to the Merger

Following the announcement of the transaction, three putative class actions were filed on behalf of PrivateBancorp stockholders in the Circuit Court of Cook County, Illinois: Solak v. Richman, et al., No. 2016-CH-08949; Parshall v. PrivateBancorp, Inc., et al., No. 2016-CH-09135; and Griffin v. PrivateBancorp, Inc., et al., No. 2016-CH-09435. The three actions have been consolidated and styled In re PrivateBancorp, Inc. Shareholder Litigation, 2016-CH-08949. All of the actions name as defendants PrivateBancorp and the members of its board of directors, and assert that the directors breached their fiduciary duties in connection with the transaction. One such case (Griffin) further asserts that PrivateBancorp aided and abetted its directors' alleged breaches. Two of the actions (Parshall and Griffin) also name as defendants CIBC and Holdco, and assert that they, too, aided and abetted the directors' purported breaches. The actions broadly allege that the transaction was the result of a flawed process, that the price is unfair, and that certain provisions of the merger agreement might dissuade a potential suitor from making a competing offer, among other things. The plaintiffs in the Parshall action have filed an amended complaint, adding a claim alleging breaches of the fiduciary duty of disclosure by the directors. Plaintiffs seek injunctive and other relief, including damages.

THE MERGER AGREEMENT

The following summary discusses certain material terms of the merger agreement. You should also read in its entirety the section entitled "The Merger" for a discussion of other material information about the merger and the merger agreement. The following description of the merger agreement is subject to, and is qualified in its entirety by reference to, the merger agreement, a copy of which is attached as Appendix A to this proxy statement/prospectus and incorporated herein by reference. We urge you to read the merger agreement in its entirety, as it is the legal document governing the merger. In the event of any discrepancy between the terms of the merger agreement and the following summary, the merger agreement will control.

Explanatory Note Regarding the Merger Agreement

The following summary of the merger agreement, and the copy of the merger agreement attached as Annex A to this proxy statement, are intended to provide information regarding the terms of the merger agreement. The merger agreement contains representations and warranties by and covenants of PrivateBancorp, CIBC and Holdco, which were made only for purposes of that agreement and as of specified dates. The representations, warranties and covenants in the merger agreement were made solely for the benefit of the parties to the merger agreement, may be subject to limitations agreed upon by the contracting parties, including being qualified by confidential disclosures made for the purposes of allocating contractual risk between the parties to the merger agreement instead of establishing these matters as facts, and may be subject to contractual standards of materiality or material adverse effect applicable to the contracting parties that generally differ from those applicable to investors. Investors are not third-party beneficiaries under the merger agreement and should not rely on the representations, warranties and covenants or any descriptions thereof as characterizations of the actual state of facts or condition of the parties thereto or any of their respective subsidiaries or affiliates. Moreover, the description of the merger agreement below does not purport to describe all of the terms of such agreement and is qualified in its entirety by reference to the full text of such agreement, a copy of which is attached hereto as Annex A and is incorporated herein by reference.

Additional information about PrviateBancorp may be found elsewhere in this proxy statement and PrivateBancorp's other public filings. See the section entitled "Where You Can Find More Information."

Effects of the Merger

At the effective time of the merger, PrivateBancorp will merge with and into Holdco, a direct wholly-owned subsidiary of CIBC, with Holdco surviving the merger. PrivateBank, which is currently a wholly-owned subsidiary of PrivateBancorp, will become a wholly-owned subsidiary of Holdco at the effective time of the merger.

As a result of the merger, there will no longer be any publicly held shares of PrivateBancorp common stock. PrivateBancorp stockholders will no longer have any direct interest in the surviving company. PrivateBancorp common stockholders will only participate in the surviving company's future earnings and potential growth through their ownership of CIBC common shares after receiving CIBC common shares as merger consideration. All of the other incidents of direct stock ownership in PrivateBancorp, such as the right to vote on certain corporate decisions, to elect directors and to receive dividends and distributions from PrivateBancorp, will be extinguished upon completion of the merger. Upon completion of the merger, shares of PrivateBancorp common stock will represent the right to receive the merger consideration. See the section entitled "The Merger—Merger Consideration."

105

Table of Contents

Effective Time of the Merger

The closing of the merger will occur no later than three business days after the satisfaction or waiver of all closing conditions, unless extended by mutual agreement of the parties. The merger will be completed and become effective as of the date and time specified in the certificate of merger to be filed with the Secretary of State of the State of Delaware on or before the closing date. As of the date of this document, the parties expect that the merger will be effective during the first calendar quarter of 2017. However, there can be no assurance as to when or if the merger will occur.

Treatment of PrivateBancorp Equity Awards

Stock Options

At the effective time, each PrivateBancorp option that is outstanding and unexercised immediately prior to the effective time shall be converted automatically into a CIBC option to purchase, on the same terms and conditions as were applicable immediately prior to the effective time, the number of CIBC common shares (rounded down to the nearest whole number of shares) equal to the product of (i) the number of shares of PrivateBancorp common stock subject to such option immediately prior to the effective time, multiplied by (ii) the sum of (A) the exchange ratio and (B) the quotient (rounded to four decimal places) obtained by dividing (1) the per share cash consideration by (2) the CIBC share closing price (as defined above in the section titled "Merger Consideration") (clause (ii), the "equity award exchange ratio"), with an exercise price per share equal to the quotient (rounded up to the nearest whole cent) obtained by dividing (x) the exercise price per share of PrivateBancorp common stock subject to such option immediately prior to the effective time, by (y) the equity award exchange ratio.

Restricted Stock

At the effective time, each award of restricted PrivateBancorp common stock that is outstanding and unvested immediately prior to the effective time shall be cancelled and replaced with an award of restricted CIBC common shares with the same terms and conditions as were applicable under such award immediately prior to the effective time, and relating to the number of CIBC common shares equal to the product of the number of shares of PrivateBancorp common stock subject to such award immediately prior to the effective time, multiplied by the equity award exchange ratio, with any fractional shares rounded to the next whole number of shares.

Restricted Stock Units

At the effective time, each PrivateBancorp restricted stock unit award that is outstanding immediately prior to the effective time shall (i) if unvested, be converted automatically into a cash-settled CIBC restricted stock unit award that is subject to the same terms and conditions as were applicable immediately prior to the effective time (except that settlement shall be in cash, with the cash payment due on settlement equal to the fair market value of CIBC common shares to which the restricted stock unit award relates) relating to the number of CIBC common shares equal to the product (taken to four decimal places) of the number of shares of PrivateBancorp common stock subject to such award immediately prior to the effective time, multiplied by the equity award exchange ratio, or (ii) if vested (including all restricted stock units held by non-employee directors, whether vested or unvested as of the date of the merger agreement, which shall be vested and settled within 10 days after the effective time), be cancelled and converted automatically into the right to receive a cash payment equal to the sum of (A) the per share cash consideration plus (B) the product of the exchange ratio multiplied by the CIBC share closing price (such sum, the "per unit total consideration"), without interest and less taxes, and a cash payment (not later than 10 days after the effective time) equal to all accumulated dividend equivalents with respect to such restricted stock unit

106

Table of Contents

award that are unpaid as of the effective time; provided, that any award that does not provide for settlement upon a change in control shall instead be converted pursuant to clause (i) above. Any PrivateBancorp restricted stock unit award for which settlement was delayed to avoid a loss of deduction pursuant to Section 162(m) of the Code will be treated as providing for settlement upon a change in control.

At the effective time, each PrivateBancorp performance share unit award that is outstanding immediately prior to the effective time shall (i) if unvested, be converted automatically into a cash-settled CIBC restricted stock unit award that is subject to the same terms and conditions as were applicable immediately prior to the effective time (except that settlement shall be in cash, with the cash payment due on settlement equal to the fair market value of CIBC common shares to which the performance share unit award relates, and that such award shall be subject solely to time based vesting) relating to the number of CIBC common shares equal to the product (taken to four decimal places) of the number of shares of PrivateBancorp common stock subject to such award immediately prior to the effective time, multiplied by the equity award exchange ratio, or (ii) if vested, be cancelled and converted automatically into the right to receive (not later than 10 days after the effective time) a cash payment equal to the per unit total consideration, without interest and less taxes, in respect of each share of PrivateBancorp common stock underlying such award and a cash payment equal to all accumulated dividend equivalents with respect to such performance share unit award that are unpaid as of the effective time; provided, that any award that does not provide for settlement upon a change in control shall instead be converted pursuant to clause (i) above. For each performance share unit award granted in 2014, 2015 or 2016 that is outstanding as of the effective time, the number of shares subject to such award will be determined assuming that applicable performance goals were achieved at the maximum level.

PrivateBancorp Deferred Units

At the effective time, each stock unit credited to an account that is deemed invested in PrivateBancorp common stock as of immediately prior to the effective time under PrivateBancorp's deferred compensation plan, shall be converted automatically into a deemed investment in CIBC common shares that will be cash-settled (with the cash payment due on settlement equal to the fair market value of CIBC common shares to which the deferred stock units relate), with the number of CIBC common shares subject to the deferred stock units in a participant's account as of the effective time to be equal to the product (taken to four decimal places) of (i) the number of shares of PrivateBancorp common stock subject to such deferred stock units as of immediately prior to the effective time, and (ii) the equity award exchange ratio. Following the effective time, the deferred compensation plan will otherwise continue to have the same terms, including payment terms and investment alternatives, that were applicable immediately prior to the effective time, with the PrivateBancorp common stock fund to be replaced with a CIBC common shares fund, and subject to all rights of PrivateBancorp and its successor to amend or terminate the deferred compensation plan.

Except in limited cases, the representations and warranties in the merger agreement do not survive the effective time of the merger and, as described below under "—Termination," if the merger agreement is validly terminated, there will be no liability under the representations and warranties of the parties, or otherwise under the merger agreement, except in the case of a party's willful and material breach of the merger agreement.

112

Table of Contents

•: agree to take, make any commitment to take, or adopt any resolutions of its board of directors in support of, any of the above prohibited actions.

Regulatory Matters. CIBC and PrivateBancorp have agreed to promptly prepare and file with the SEC a registration statement on Form F-4, of which this proxy statement/prospectus is a part. CIBC and PrivateBancorp have agreed to use reasonable best efforts to have the Form F-4 declared effective under the Securities Act as promptly as practicable after such filing, and to mail or deliver the proxy statement/prospectus to PrivateBancorp's stockholders. CIBC has also agreed to use its reasonable best efforts to obtain all necessary state securities law or "Blue Sky" permits and approvals required to consummate the merger, and PrivateBancorp has agreed to furnish all information concerning PrivateBancorp and the holders of PrivateBancorp common stock as may be reasonably requested in connection with any such action.

CIBC and PrivateBancorp have agreed to cooperate with each other and use their respective reasonable best efforts to promptly prepare and file all necessary documentation, to effect all applications, notices, petitions and filings, to obtain as promptly as practicable all permits, consents, approvals and authorizations of all third parties and governmental entities that are necessary or advisable to consummate the merger.

Moreover, each of CIBC and PrivateBancorp has agreed to use its reasonable best efforts to avoid the entry of, or to have vacated, lifted, reversed or overturned any decree, judgment, injunction or other order, whether temporary, preliminary or permanent, that would restrain, prevent or delay the closing.

Additionally, each of CIBC and PrivateBancorp has agreed to furnish to the other all information concerning itself, its subsidiaries, directors, officers and shareholders and such other matters as may be reasonably necessary or advisable in connection with this proxy statement/prospectus, the Form F-4 or any other statement, filing, notice or application made by or on behalf of CIBC, PrivateBancorp or any of their respective subsidiaries to any governmental entity in connection with the merger.

Stockholder Approval. PrivateBancorp's board of directors has resolved to recommend to the PrivateBancorp common stockholders that they approve the merger agreement and the transactions contemplated thereby and to submit to the PrivateBancorp common stockholders the merger agreement and any other matters required to be approved by the PrivateBancorp common stockholders in order to carry out the intentions of the merger agreement.

Employee Matters. During the period commencing at the effective time of the merger and ending on October 31, 2018 (which we refer to as the "Continuation Period"), CIBC shall cause the surviving corporation to provide each employee of PrivateBancorp or any of its subsidiaries as of the effective time of the merger who remains employed by CIBC or any of its affiliates (including the surviving corporation and its subsidiaries) following the effective time of the merger (which we refer to as a "continuing employee") with (i) an annual base salary or base wage rate that is no less than that provided to such employee by PrivateBancorp and its subsidiaries immediately prior to the effective time of the merger, (ii) a total incentive compensation opportunity that is no less than the aggregate total incentive compensation opportunity (whether relating to annual or any other type of incentive compensation) provided to such employee by PrivateBancorp and its subsidiaries immediately prior to the effective time of the merger, and (iii) employee benefits that are substantially comparable in the aggregate to those provided to such employees by PrivateBancorp and its subsidiaries immediately prior to the effective time of the merger. CIBC and PrivateBancorp have also agreed to certain terms and conditions that will apply to the long-term incentive awards granted to continuing employees in respect of calendar year 2016, the 2017 annual short-term incentive awards for continuing employees and, to the extent applicable, the mandatory 2016 annual bonus deferrals for continuing employees. During the period commencing at the effective time of the merger and ending on the second anniversary of the effective time of the merger, CIBC shall continue to maintain or cause to be maintained, without amendment, PrivateBancorp's severance plan applicable to continuing employees immediately prior to the effective time of the merger, and shall provide, or cause to be provided, to each continuing employee whose employment is terminated during the continuation period without "cause", as such term is defined or concept is used for purposes of the PrivateBancorp severance plan, or who otherwise experiences a severance-qualifying termination under the PrivateBancorp severance plan, with the severance benefits specified in the PrivateBancorp severance plan.

With respect to any employee benefit plans of CIBC or its subsidiaries in which any employees of PrivateBancorp or its subsidiaries become eligible to participate on or after the effective time of the merger (which we refer to as "new plans"), CIBC shall or shall cause the surviving corporation to: (i) use commercially reasonable efforts to (A) waive all pre-existing conditions, exclusions and waiting periods with respect to participation and coverage requirements applicable to each such employee and his or her eligible dependents under any new plans, except to the extent such pre-existing conditions, exclusions or waiting periods would apply under the analogous PrivateBancorp benefit plan, and (B) provide each such employee and his or her eligible dependents with credit for any co-payments or deductibles paid prior to the effective time of the merger under a PrivateBancorp benefit plan (to the same extent that such credit was given under the analogous PrivateBancorp benefit plan prior to the effective time of the merger) in satisfying any applicable deductible or out-of-pocket requirements under any new plans; and (ii) recognize all service of each such employee with PrivateBancorp and its subsidiaries (and their respective predecessors, if applicable) for all purposes in any new plan; provided that the foregoing service recognition shall not apply (A) to the extent it would result in duplication of benefits for the same period of services, (B) for purposes of any defined benefit pension plan or benefit plan that provides retiree welfare benefits, or (C) to any benefit plan that is a frozen plan or provides grandfathered benefits.

114

Table of Contents

CIBC and PrivateBancorp have agreed to the establishment of a cash retention pool which may be awarded in the form of cash and cash-settled CIBC restricted stock units to employees of PrivateBancorp and its subsidiaries, including executive officers.

Indemnification and Directors' and Officers' Insurance. From and after the effective time of the merger, CIBC shall cause Holdco (the surviving entity in the merger) to indemnify and hold harmless each present and former director, officer or employee of PrivateBancorp and its subsidiaries or fiduciaries of PrivateBancorp or any of its subsidiaries under PrivateBancorp benefit plans (in each case, when acting in such capacity) (collectively, the "PrivateBancorp Indemnified Parties") against any costs or expenses (including reasonable attorneys' fees), judgments, fines, losses, damages or liabilities incurred in connection with any threatened or actual claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative, whether arising before or after the effective time of the merger, arising in whole or in part out of (i) the fact that such person is or was a director, officer or employee of PrivateBancorp or any PrivateBancorp subsidiary or is or was a fiduciary of PrivateBancorp or any of its subsidiaries under PrivateBancorp benefit plans or (ii) matters, acts or omissions existing or occurring at or prior to the effective time of the merger, including the transactions contemplated thereby to the same extent as such persons are indemnified as of the date of the merger agreement by PrivateBancorp pursuant to PrivateBancorp's certificate of incorporation, by-laws, governing or organizational documents of any PrivateBancorp subsidiary and any indemnification agreements in existence as of the date of the merger agreement; and CIBC will also cause the surviving corporation to advance expenses as incurred by such PrivateBancorp Indemnified Party to the same extent as such persons are entitled to advancement of expenses as of the date of the merger agreement by PrivateBancorp pursuant to the PrivateBancorp's certificate of incorporation, by-laws, governing or organizational documents of any PrivateBancorp subsidiary and any indemnification agreements in existence as of the date of the merger agreement; provided that the PrivateBancorp Indemnified Party to whom expenses are advanced provides an undertaking (in a reasonable and customary form) to repay such advances if it is ultimately determined that such PrivateBancorp Indemnified Party is not entitled to indemnification.

CIBC has agreed to provide directors' and officers' liability insurance that serves to reimburse the present and former officers and directors of PrivateBancorp or any of its subsidiaries with respect to claims against such directors and officers arising from facts or events occurring at or before the effective time of the merger for a period of six years following the effective time of the merger. The insurance will contain terms and conditions that are not less advantageous than the current coverage provided by PrivateBancorp, except that CIBC is not required to incur annual premium expense greater than 300% of PrivateBancorp's current aggregate annual directors' and officers' liability insurance premium. At or prior to the effective time of the merger and in lieu of the foregoing, PrivateBancorp, in consultation with CIBC, may purchase and pay for a tail policy for directors' and officers' liability insurance on the terms described in this paragraph.

No Solicitation. The merger agreement precludes PrivateBancorp and its subsidiaries and their respective officers, directors, agents, advisors and affiliates from initiating, soliciting, encouraging or knowingly facilitating inquiries or proposals with respect to, or engaging in any negotiations concerning, or providing any confidential or nonpublic information or data to, or having any discussions with, any person relating to, any Acquisition Proposal (defined below). However, if PrivateBancorp, prior to receipt of the requisite affirmative vote of the PrivateBancorp common stockholders, receives an unsolicited bona fide Acquisition Proposal and PrivateBancorp's board of directors concludes in good faith that such Acquisition Proposal constitutes or is more likely than not to result in a Superior Proposal (defined below), PrivateBancorp may, and may permit its subsidiaries and its and its subsidiaries' representatives to, furnish or cause to be furnished nonpublic information or data and participate in such negotiations or discussions to the extent that its board of directors concludes in good faith (after receiving the advice of its outside counsel, and with respect to financial matters, its

115

Table of Contents

financial advisors) that failure to take such actions would result in a violation of its fiduciary duties under applicable law. PrivateBancorp has also agreed to advise CIBC within 24 hours following receipt of any Acquisition Proposal and of the substance of the Acquisition Proposal (including the identity of the person making such Acquisition Proposal), and will keep CIBC promptly apprised of any developments.

•: As used in the merger agreement, "Acquisition Proposal" means, other than the transactions contemplated by the merger agreement, any offer, proposal, inquiry or indication of interest relating to (i) any acquisition or purchase, direct or indirect, of 20% or more of the consolidated assets of PrivateBancorp and its subsidiaries or 20% or more of any class of voting securities of PrivateBancorp or its subsidiaries whose assets, individually or in the aggregate, constitute more than 20% of the consolidated assets of PrivateBancorp, (ii) any tender offer or exchange offer that, if consummated, would result in such third party beneficially owning 20% or more of any class of equity or voting securities of PrivateBancorp or its subsidiaries whose assets, individually or in the aggregate, constitute more than 20% of the consolidated assets of PrivateBancorp, or (iii) a merger, consolidation, share exchange, other business combination, reorganization, recapitalization, liquidation, dissolution or other similar transaction involving PrivateBancorp or its subsidiaries whose assets, individually or in the aggregate, constitute more than 20% of the consolidated assets of PrivateBancorp, except, in each case, any sale of whole loans and securitizations in the ordinary course of business and any bona fide internal reorganization.
•: As used in the merger agreement, "Superior Proposal" means a bona fide written Acquisition Proposal that the board of directors of PrivateBancorp concludes in good faith to be more favorable from a financial point of view to its stockholders than the merger and the other transactions contemplated by the merger agreement, (i) after receiving the advice of its financial advisors (who must be a nationally recognized investment banking firm), (ii) after taking into account the likelihood of consummation of such transaction on the terms set forth therein and (iii) after taking into account all legal (with the advice of outside counsel), financial (including the financing terms of any such proposal), regulatory and other aspects of such proposal (including any expense reimbursement provisions and conditions to closing) and any other relevant factors permitted under applicable law; provided, that for purposes of the definition of "Superior Proposal," the references to "20%" in the definition of Acquisition Proposal shall be deemed to be references to "a majority."

Change of Methods. CIBC may at any time change the method of effecting the transactions contemplated in the merger agreement, provided that no such change or amendment (i) alters or changes the amount or kind of the merger consideration, (ii) adversely affects the tax treatment of the merger with respect to PrivateBancorp's stockholders or (iii) be reasonably likely to cause the closing to be materially delayed or the receipt of the requisite regulatory approvals to be prevented or materially delayed.

Restructuring Efforts. If the PrivateBancorp stockholders do not approve the merger at the special meeting or at any adjournment or postponement thereof, CIBC and PrivateBancorp have agreed to use reasonable best efforts to negotiate a restructuring of the merger and/or to resubmit the merger to PrivateBancorp's stockholders for approval; however, neither CIBC nor PrivateBancorp will be required to alter any material terms of the merger agreement or adversely affect the tax treatment of the merger with respect to PrivateBancorp stockholders in any such negotiations.

Corporate Governance. CIBC has agreed to take all appropriate action so that, as of the effective time of the merger, subject to CIBC's organizational documents, policies and applicable law and regulation, one individual designated by PrivateBancorp and reasonably acceptable to CIBC (the "Company Director") shall be appointed as an independent director of CIBC. The Company Director

116

Table of Contents

shall thereafter be nominated for election as a director of CIBC, subject to the approval of the board of directors of CIBC, at CIBC's first annual meeting of shareholders after the closing.

Moreover, CIBC has agreed to take all appropriate action so that, as of the effective time of the merger, subject to CIBC's organizational documents, policies and applicable law and regulation, the board of directors of Holdco (and any successor thereto) will be comprised of nine directors, of whom three independent directors and one non-independent director (who is expected to be Mr. Richman) will be individuals designated by PrivateBancorp and reasonably acceptable to CIBC, subject to Holdco's organizational documents, policies and applicable law and regulation.

CIBC has also agreed to take all appropriate action so that, as of the effective time of the merger, subject to CIBC's organizational documents, policies and applicable law and regulation, the board of directors of PrivateBank (and any successor thereto) will be comprised of nine directors, of whom three independent directors and one non-independent director (who is expected to be Mr. Richman) will be individuals designated by PrivateBancorp and reasonably acceptable to CIBC, subject to PrivateBank's organizational documents, policies and applicable law and regulation.

The parties have agreed that, at the effective time of the merger, PrivateBank will be headquartered in Chicago, Illinois, and Holdco and PrivateBank will constitute the primary banking, lending and wealth management platform of CIBC in the United States.

The merger agreement may be terminated at any time prior to the effective time of the merger, whether before or after approval of the merger by PrivateBancorp stockholders:

•: by mutual written consent of CIBC and PrivateBancorp;
•: by either PrivateBancorp or CIBC, if any of the required regulatory approvals are denied or completion of the merger has been prohibited or made illegal by a governmental entity (and the denial or prohibition is final and non-appealable);
•: by either PrivateBancorp or CIBC, if the merger has not been completed by June 29, 2017 (the "Termination Date"), unless the failure to complete the merger by that date is due to the terminating party's failure to abide by the merger agreement;
•: by either PrivateBancorp or CIBC, if there is a breach by the other party that would result in the failure of the conditions of the terminating party's obligation to complete the merger, unless the breach is capable of being, and is, cured within 60 days of written notice of the breach (provided that the terminating party is not then in material breach of the merger agreement); or
•: by CIBC, if (a) PrivateBancorp or its board of directors (i) submits the merger agreement to its stockholders without a recommendation for approval, or otherwise withdraws or materially and adversely modifies (or discloses its intention to withdraw or materially and adversely modify) its recommendation for approval, or recommends to its stockholders an Acquisition Proposal other than the merger, or (ii) materially breaches its obligation to call a stockholder meeting or prepare and mail its stockholders the proxy statement/prospectus pursuant to the merger agreement; or (b) if a tender or exchange offer for 20% or more of the outstanding shares of PrivateBancorp common stock is commenced (other than by CIBC), and PrivateBancorp's board of directors recommends that the PrivateBancorp stockholders tender their shares in such tender or exchange offer or otherwise fails to recommend that such stockholders reject such tender or exchange offer within 10 business days.

Effect of Termination and Termination Fee

If the merger agreement is validly terminated, the agreement will become void without any liability on the part of any of the parties unless a party has willfully and materially breached the merger agreement. However, the provisions of the merger agreement relating to authority, fees and expenses

118

Table of Contents

and the confidentiality obligations of the parties will continue in effect notwithstanding termination of the merger agreement.

In the event that (i) after the date of the merger agreement, a bona fide Acquisition Proposal is made known to senior management of PrivateBancorp or is made directly to its stockholders generally or any person has publicly announced (and not withdrawn) an Acquisition Proposal with respect to PrivateBancorp and thereafter (x) the merger agreement is terminated by either CIBC or PrivateBancorp due to the merger not being completed by the Termination Date without the requisite stockholder vote having been obtained or (y) the merger agreement is terminated by CIBC due to a breach by PrivateBancorp of any of the covenants or agreements or any of the representations or warranties pursuant to Section 8.1(d) of the merger agreement, and (ii) prior to the date that is 15 months after the date of any applicable termination referred to in sub clauses (x) or (y), PrivateBancorp enters into a definitive agreement or consummates a transaction with respect to an Acquisition Proposal (whether or not the same Acquisition Proposal as that referred to above), then PrivateBancorp will pay CIBC a termination fee equal to $150,000,000 (the "Termination Fee"); provided, that for this purpose all references in the definition of Acquisition Proposal to "20%" shall instead refer to "50%."

The Termination Fee would also be payable by PrivateBancorp to CIBC if the merger is terminated by CIBC because (a) PrivateBancorp or PrivateBancorp's board of directors (i) submits the merger agreement to its stockholders without a recommendation for approval, or otherwise withdraws or materially and adversely modifies (or discloses its intention to withdraw or materially and adversely modify) its recommendation for approval, or recommends to its stockholders an Acquisition Proposal other than the merger, or (ii) materially breaches its obligation to call a stockholder meeting or prepare and mail its stockholders the proxy statement/prospectus pursuant to the merger agreement; or (b) if a tender or exchange offer for 20% or more of the outstanding shares of PrivateBancorp common stock is commenced (other than by CIBC), and PrivateBancorp's board of directors recommends that the PrivateBancorp stockholders tender their shares in such tender or exchange offer or otherwise fails to recommend that such stockholders reject such tender or exchange offer within 10 business days. In response to a specific request from the Federal Reserve Board relating to CIBC's application under the Bank Holding Company Act in connection with the merger, CIBC has committed to the Federal Reserve Board that it will only require PrivateBancorp to pay the Termination Fee applicable in these circumstances in respect of the 12 month period (rather than the 15 month period) after the date of the applicable termination.

Amendments, Extensions and Waivers

The merger agreement may be amended by the parties, by action taken or authorized by their respective boards of directors, at any time before or after approval of the merger agreement by the PrivateBancorp stockholders, in writing signed on behalf of each of the parties, subject to applicable law.

At any time prior to the effective time of the merger, the parties, by action taken or authorized by their respective boards of directors, may, to the extent permitted by law, (a) extend the time for the performance of any of the obligations or other acts of the other parties, (b) waive any inaccuracies in the representations and warranties contained in the merger agreement or (c) waive compliance with any of the agreements or conditions contained in the merger agreement. Any agreement on the part of a party to any extension or waiver must be in writing.

Fees and Expenses

Except with respect to costs and expenses of printing and mailing this proxy statement/prospectus and all filing and other fees paid to the SEC in connection with the merger, which will be borne equally by CIBC and PrivateBancorp, all fees and expenses incurred in connection with the merger, the merger agreement, and the transactions contemplated by the merger agreement will be paid by the party incurring such fees or expenses, whether or not the merger is consummated.

While recipients of RSUs and PSUs have no voting power with respect to the underlying shares until the units settle (and no executive's RSUs or PSUs are scheduled to settle within 60 days of the date of this table), they are included because the structure of the Company's director and executive compensation programs places significant emphasis on the use of RSUs and PSUs with delayed settlement features. To exclude vested RSUs and PSUs (which the recipient has a legal right to receive in the future) solely because there are no current voting rights would not accurately reflect their financial interest in the Company. With respect to directors, the table includes (1) all vested RSUs that have not yet settled because the director may receive the underlying shares upon leaving the board at any time and (2) those unvested RSUs that are subject to vesting on the basis of continued board service between September 30, 2016 and November 30, 2016.

DESCRIPTION OF CIBC SHARE CAPITAL

Set forth below is a summary of the material terms of CIBC's share capital and material provisions of the Bank Act and CIBC's by-laws as they relate to CIBC's share capital. The following summary is not complete and is qualified in its entirety by the Bank Act, CIBC's by-laws and the actual terms and conditions of such shares. We urge you to read the provisions of the Bank Act (in particular, Sections 372-408 and the definitions in Sections 2.2 and 8) and CIBC's by-laws, which are relevant to a full understanding of CIBC's share capital. Copies of CIBC's by-laws are available, without charge, to any person by following the instructions listed in the section entitled "Where You Can Find More Information." For more information on the provisions of the Bank Act and CIBC's by-laws, see also section entitled "Comparison of Rights of CIBC Shareholders and PrivateBancorp Stockholders."

CIBC Share Capital

CIBC's authorized share capital consists of (i) an unlimited number of common shares, without nominal or par value, (ii) an unlimited number of Class A preferred shares, without nominal or par value, provided that the maximum aggregate consideration for all outstanding Class A preferred shares at any time may not exceed C$10 billion and (iii) an unlimited number of Class B preferred shares, without nominal or par value, provided that the maximum aggregate consideration for all outstanding Class B preferred shares at any time may not exceed C$10 billion. As at the end of the fiscal year, October 31, 2015, CIBC had issued and outstanding 397,284,577 common shares, 40,000,000 Class A preferred shares (Series 39, 41 and 43) and no Class B preferred shares.

CIBC Common Shares

Shareholder Meetings and Voting

A holder of common shares is entitled to notice of and to attend all shareholders' meetings, except meetings at which only holders of a specified class or series of shares are entitled to vote, and for all purposes will be entitled to one vote for each common share held.

Size of Board of Directors

The Bank Act requires that the number of directors on CIBC's board of directors be at least seven. All directors of CIBC are elected annually. The Bank Act also requires that at least a majority of the directors on CIBC's board of directors must be, at the time of each director's election or appointment, resident Canadians.

Dividends

The holders of common shares are entitled to receive dividends as and when declared by the board of directors of CIBC, subject to the preference of holders of preferred shares.

Liquidation Rights

In the event of liquidation, dissolution or winding up of CIBC, after payment of all outstanding deposits and debts and subject to the preference of any shares ranking senior to the common shares, the holders of common shares will be entitled to a pro rata distribution of the remaining assets of CIBC.

Preemptive, Subscription, Redemption and Conversion Rights

The holders of common shares have no pre-emptive, subscription, redemption or conversion rights. The rights, preferences and privileges of the common shares are subject to the rights of the holders of preferred shares.

122

Table of Contents

CIBC Preferred Shares

Class A preferred shares and Class B preferred shares are issuable in series with such rights, privileges, restrictions and conditions as the board of directors of CIBC, subject to the provisions of the Bank Act, may determine from time to time.

The Bank Act requires that banks maintain adequate capital in relation to their operations. The Superintendent of Financial Institutions (Canada) establishes capital adequacy requirements for issuances of regulatory capital by banks. These requirements include that all regulatory capital must be able to absorb losses in a failed financial institution. Effective January 1, 2013, in accordance with capital adequacy requirements adopted by the Superintendent of Financial Institutions (Canada), non-common capital instruments issued after January 1, 2013, including preferred shares, must include non-viability contingent capital provisions, providing for the full and permanent automatic conversion (an "NVCC Automatic Conversion") of such non-common capital instruments into common shares upon the occurrence of certain trigger events relating to financial viability (the "NVCC Provisions") in order to qualify as regulatory capital.

Certain Conditions of the Class A Preferred Shares as a Class

Priority

Each series of Class A preferred shares rank on a parity with every other series of Class A preferred shares and rank in priority to the Class B preferred shares and the common shares of CIBC with respect to the payment of dividends and on the distribution of assets in the event of the liquidation, dissolution or winding-up of CIBC, provided that an NVCC Automatic Conversion as contemplated under the NVCC Provisions applicable to a series of Class A preferred shares has not occurred.

Restrictions on Creation of Additional Class A Preferred Shares

In addition to any shareholder approvals required by applicable law, including the Bank Act, the approval of the holders of the Class A preferred shares given in the manner described under the section titled "Modification" below, is required for any increase in the maximum aggregate consideration for which the Class A preferred shares may be issued and for the creation of any shares ranking prior to or on a parity with the Class A preferred shares.

Modification

Approval of amendments to the provisions of the Class A preferred shares as a class and any other authorization required to be given by the holders of Class A preferred shares may be given by a resolution carried by an affirmative vote of not less than 66²/3% of the votes cast at a meeting at which the holders of 10% of the outstanding Class A preferred shares are present or represented by proxy or, if no quorum is present at such meeting, at an adjourned meeting at which the shareholders then present would form the necessary quorum.

Rights on Liquidation

In the event of the liquidation, dissolution or winding-up of CIBC, provided that a NVCC Automatic Conversion as contemplated under the NVCC Provisions applicable to a series of Class A preferred shares has not occurred, the holders of the Class A preferred shares will be entitled to receive an amount equal to the price at which such shares are issued together with such premium, if any, as shall have been provided for with respect to the Class A preferred shares of any series, together with all declared and unpaid dividends, before any amount is paid or any assets of CIBC are distributed to the holders of any shares ranking junior to the Class A preferred shares. Upon payment

123

Table of Contents

to the holders of the Class A preferred shares of the amounts so payable to them, they will not be entitled to share in any further distribution of the assets of CIBC. If an NVCC Automatic Conversion as contemplated under the NVCC Provisions applicable to a series of Class A preferred shares has occurred, all of the Class A preferred shares of such series shall have been converted into common shares of CIBC in accordance with a pre-determined conversion formula specified at the time of issuance of the Class A preferred shares of such series and will rank on parity with all other common shares of CIBC.

Voting Rights

Subject to the provisions of the Bank Act, the directors of CIBC are empowered to set voting rights, if any, for each series of Class A preferred shares.

Contingent Conversion of Certain Series of Class A Preferred Shares

All of CIBC's currently outstanding Class A preferred shares (Series 39, 41 and 43) were issued after January 1, 2013 and, accordingly, contain NVCC Provisions in their respective share terms and conditions. The number of common shares into which such Class A preferred shares would be converted upon an NVCC Automatic Conversion will be determined in accordance with a pre-determined conversion formula specified at the time of issuance of such Class A preferred shares.

Bank Act Restrictions Related to Share Ownership

The Bank Act contains restrictions on the issue, transfer, acquisition, beneficial ownership and voting of all shares of a chartered bank. By way of summary, no person, or persons acting jointly or in concert, shall be a major shareholder of a bank if the bank has equity of C$12 billion or more (which would include CIBC). A person is a major shareholder of a bank where (i) the aggregate of the shares of any class of voting shares beneficially owned by that person, by entities controlled by that person and by any person associated or acting jointly or in concert with that person (as contemplated by the Bank Act) is more than 20% of that class of voting shares or (ii) the aggregate of the shares of any class of non-voting shares beneficially owned by that person, by entities controlled by that person and by any person associated or acting jointly or in concert with that person (as contemplated by the Bank Act) is more than 30% of that class of non-voting shares. No person, or persons acting jointly or in concert, shall have a significant interest in any class of shares of a bank, including CIBC, unless the person first receives the approval of the Minister of Finance (Canada). For purposes of the Bank Act, a person has a significant interest in a class of shares of a bank where the aggregate of any shares of the class beneficially owned by that person, by entities controlled by that person and by any person associated or acting jointly or in concert with that person (as contemplated by the Bank Act) exceeds 10% of all of the outstanding shares of that class of shares of such bank. If a person contravenes any of these restrictions, the Minister of Finance may, by order, direct that person to dispose of all or any portion of those shares.

In addition, the Bank Act prohibits a bank, including CIBC, from recording in its securities register the transfer or issuance of shares of any class to Her Majesty in right of Canada or of a province, an agent or agency of Her Majesty, a government of a foreign country or any political subdivision of a foreign country, or an agent or agency of a foreign government. The Bank Act also suspends the exercise of any voting rights attached to any share of a bank, including CIBC, that is beneficially owned by Her Majesty in right of Canada or of a province, an agency of Her Majesty, a government of a foreign country or any political subdivision of a foreign country, or any agency thereof.

Under the Bank Act, CIBC cannot purchase any of its shares, including its common shares, or redeem any of its redeemable shares unless the prior consent of the Superintendent of Financial Institutions (Canada) has been obtained. In addition, the Bank Act prohibits a bank from purchasing

124

Table of Contents

any of its shares or redeeming any of its redeemable shares or paying any dividends if there are reasonable grounds for believing that the bank is, or the payment would cause the bank to be, in contravention of the Bank Act's requirement to maintain, in relation to the bank's operations, adequate capital and appropriate forms of liquidity and to comply with any regulations or directions of the Superintendent of Financial Institutions (Canada) in relation thereto.

Bank Act Implications for the Amendments to the Rights, Privileges, Restrictions and Conditions of CIBC's Share Capital

Under the Bank Act, the rights of holders of CIBC's shares can be changed by the board of directors of CIBC by making, amending or repealing the by-laws of CIBC. The board of directors of CIBC must submit such by-law, or amendment to or repeal of a by-law, to the shareholders of CIBC in accordance with the procedures of the Bank Act and the by-laws of CIBC, and the shareholders must approve the by-law, amendment to or repeal of the by-law, by special resolution to be effective. Under the Bank Act, a special resolution is a resolution passed by not less than two-thirds of the votes cast by or on behalf of the shareholders who voted in respect of that resolution or signed by all the shareholders entitled to vote on that resolution. In some circumstances, the Bank Act mandates that holders of shares of a class or a series are entitled to vote separately as a class or series on a proposal to amend the by-laws of the bank.

COMPARISON OF RIGHTS OF CIBC SHAREHOLDERS AND PRIVATEBANCORP STOCKHOLDERS

Upon completion of the merger, PrivateBancorp stockholders that receive CIBC shares as part of their merger consideration will become CIBC shareholders. CIBC is a Canadian bank chartered under the Bank Act and, accordingly, the rights and privileges of CIBC shareholders will be governed principally by the Bank Act, which is CIBC's charter, and by CIBC's by-laws. PrivateBancorp is incorporated under the laws of the State of Delaware and, accordingly, the rights and privileges of PrivateBancorp stockholders will be governed principally by the laws of the State of Delaware, particularly the Delaware General Corporation Law, referred to as the "DGCL," PrivateBancorp's restated certificate of incorporation, referred to as its "certificate of incorporation", and PrivateBancorp's amended and restated by-laws.

The following is a summary of the key differences among the rights of PrivateBancorp stockholders and the rights of CIBC shareholders.

While CIBC and PrivateBancorp believe that the following summary describes the key differences among the rights of PrivateBancorp stockholders as of the date of this proxy statement/prospectus and the rights of CIBC shareholders as of the date of this proxy statement/prospectus, it may not contain all of the information that is important to you and it is not meant to be relied upon as an exhaustive list. We urge you to read the governing instruments of each company and the provisions of the DGCL and the Bank Act, which are relevant to a full understanding of the governing instruments, fully and in their entirety. Copies of the governing instruments are available, without charge, to any person by following the instructions listed in the section entitled "Where You Can Find More Information."

Authorized Capital Stock

PrivateBancorp

PrivateBancorp's certificate of incorporation authorizes the issuance of up to 174,000,000 shares of PrivateBancorp common stock, without par value, up to 5,000,000 shares of non-voting common stock, without par value, and up to 1,000,000 shares of PrivateBancorp preferred stock, without par value. PrivateBancorp preferred stock is issuable in series, each series having such designations, terms, limitations, rights and preferences as the board of directors may fix and determine.

CIBC

CIBC's by-laws permit CIBC to issue an unlimited number of common shares without nominal or par value and an unlimited number of Class A preferred shares and Class B preferred shares, without nominal or par value, which classes of preferred shares may be issued for a maximum aggregate consideration not to exceed C$10 billion for each class of preferred shares (subject to certain exceptions in the event of liquidation, dissolution or winding up of CIBC).

Number, Classification and Election of Directors

PrivateBancorp

PrivateBancorp's certificate of incorporation and by-laws provide that the number of directors will be 15 directors; provided, however, that the number of directors may be increased or decreased from time to time by resolution of the board of directors. Directors are elected by the stockholders at the annual meeting of stockholders by a plurality of the votes cast. The holders of PrivateBancorp common stock are not entitled to cumulative voting rights in director elections. There are currently 11 directors of PrivateBancorp.

126

Table of Contents

CIBC

The Bank Act requires that the number of directors on CIBC's board be at least seven. CIBC's by-laws provide that the maximum number of directors on the board is 35. Currently, CIBC's board consists of 17 directors who are elected annually. At every meeting of shareholders, every question, including the election of the board of directors, unless otherwise required by the Bank Act or the by-laws, is to be determined by a majority of the votes cast on the question. If there is an equality of votes cast by the shareholders, the chairman of the meeting shall be entitled to a second or casting vote, except, however, for the election of directors. The holders of Class A preferred shares and Class B preferred shares are not entitled to vote at any meeting of shareholders of CIBC nor are they entitled to receive any notice of or attend shareholders' meetings except as provided in the Bank Act or in the rights, privileges, restrictions and conditions attached to the applicable series of such class of shares. The Bank Act also requires that no more than two-thirds of the directors may be affiliated with CIBC, and no more than 15% of the directors may be employees of CIBC or a subsidiary of CIBC, except that up to four persons who are employees of CIBC or a subsidiary may be directors if they constitute not more than 50% of the directors of CIBC. Additionally, under the Bank Act, a majority of the directors of CIBC must be resident Canadians and, except in limited circumstances, directors may not transact business at a meeting of directors at which a majority of the directors present are not resident Canadians. The Bank Act also requires the directors of a bank to appoint from their members a chief executive officer who must be ordinarily resident in Canada.

Filling Vacancies on the Board of Directors and Removing Directors

PrivateBancorp

Section 141(k) of the DGCL provides that any director or the entire board of directors may be removed, with or without cause, by the holders of a majority of the shares then entitled to vote at an election of directors. PrivateBancorp's certificate of incorporation do not provide for any limitations to this rule.

The by-laws of PrivateBancorp allow for vacancies (including by reason of an increase in the number of authorized directors) to be filled by the majority of the directors then in office or by the sole remaining director.

CIBC

Under the Bank Act, a quorum of directors may fill a vacancy among the directors except a vacancy resulting from a change in the by-laws by which the minimum or maximum number of directors is increased or from a failure to elect the minimum number of directors provided for in the by-laws.

Additionally, CIBC's by-laws allow the directors to appoint one or more additional directors, within the maximum number permitted by CIBC's by-laws, to hold office for a term expiring not later than the close of the next annual meeting of shareholders; but, pursuant to the Bank Act, the total number of directors so appointed may not exceed one-third of the number of directors elected at the previous annual meeting of shareholders.

At any meeting of CIBC's board of directors, a majority of the directors, or such greater number as the board may from time to time determine, shall constitute a quorum for the transaction of business providing that not more than one of such directors is a full-time officer of CIBC. The Bank Act provides that the directors of a bank will not transact business at a meeting of directors unless at least one of the directors who is not affiliated with the bank is present and a majority of the directors present are resident Canadians.

Regarding directors removal, under the Bank Act, the shareholders of CIBC may remove any director or all the directors from office by a majority of votes cast at a special meeting of shareholders.

Voting Rights Generally

PrivateBancorp

Under the DGCL and the PrivateBancorp certificate of incorporation, each share of PrivateBancorp common stock is entitled to one vote per share on all matters submitted to stockholders.

CIBC

Under the Bank Act, if voting rights are attached to any share of a bank, the voting rights may confer only one vote in respect of that share. The CIBC by-laws provide that holders of CIBC common shares are entitled to vote at all meetings of shareholders, except where only holders of a specified class of shares are entitled to vote. The holders of Class A preferred shares and Class B preferred shares are not entitled to vote at any meeting of shareholders of CIBC nor are they entitled to receive any notice of or attend shareholders' meetings except as provided in the Bank Act or in the rights, privileges, restrictions and conditions attached to the applicable series of such class of shares.

Exculpation of Liability

PrivateBancorp

Under PrivateBancorp's certificate of incorporation, directors are not liable to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director except for liability (i) for any breach of the director's duty of loyalty to the corporation or its stockholders; (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law; (iii) under Section 174 of Delaware law (which concerns unlawful dividends, stock purchases, and redemptions); or (iv) for any transaction from which the director derived an improper personal benefit.

CIBC

Under the Bank Act, a bank may not, by contract, resolution or by-law, limit the liability of its directors for breaches of their duty to act in accordance with the Bank Act. However, under the Bank Act, directors and officers are not liable in respect of certain of their duties imposed under the Bank Act, including their duty of care, if they relied in good faith (a) on financial statements represented to the directors or officers by an officer of the bank or in a written report of the bank's auditors to reflect fairly the financial condition of the bank or (b) on a report of a person whose profession lends credibility to a statement made by the professional.

Director and Officer Indemnification

PrivateBancorp

Under Delaware law, a corporation may indemnify its directors and officers if a director or officer acted in good faith and in a manner reasonably believed to be in, or not opposed to, the best interests of the corporation. Furthermore, Delaware law allows for a corporation to indemnify its directors and officers with respect to any criminal action, suit or proceeding when the director or officer had no reasonable cause to believe his or her conduct was unlawful. Indemnification generally is not allowed under Delaware law if a director or officer has been adjudged liable to the corporation.

PrivateBancorp's certificate of incorporation provides that directors and officers of the corporation shall be indemnified to the fullest extent permissible under Delaware law and not prohibited by other law or regulation, subject to certain conditions.

128

Table of Contents

CIBC

Subject to the limitations contained in the Bank Act, but without limit to the right of CIBC to indemnify or advance amounts to any person under the Bank Act or otherwise, CIBC's by-laws provide that CIBC will indemnify a director or officer of CIBC, a former director or officer of CIBC, or another person who acts or acted at CIBC's request as a director or officer of or in a similar capacity to another entity, and such person's heirs and personal representatives (the "indemnified persons"), against all costs, charges and expenses, including an amount paid to settle an action or satisfy a judgment, reasonably incurred by such person in respect of any civil, criminal, administrative, investigative or other proceeding to which such person is involved because of that association with CIBC or an other entity; provided: (i) the indemnified person acted honestly and in good faith with a view to the best interests of, as the case may be, CIBC or the other entity for which they acted at CIBC's request as a director or officer in a similar capacity; and (ii) in the case of a criminal or administrative action or proceeding that is enforced by a monetary penalty, such person had reasonable grounds for believing their conduct was lawful. CIBC's by-laws further provide that nothing in its by-laws shall limit the right of any person entitled to indemnity to claim indemnity apart from the provisions of CIBC's by-laws.

Under the Bank Act, the indemnified persons referred to above are entitled to indemnity from CIBC in respect of all costs, charges and expenses, including an amount paid to settle an action or satisfy a judgment, reasonably incurred by the person in connection with the defense of any civil, criminal, administrative, investigative or other proceeding to which the person is subject because of their association with CIBC or another entity, if the person seeking indemnity:

•: was not judged by the court or other competent authority to have committed any fault or omitted to do anything they ought to have done; and
•: fulfils the conditions set out in (i) and (ii) above.

CIBC has obtained director's and officer's liability insurance coverage, which, subject to policy terms and limitations, provides coverage for directors and officers of CIBC, acting as directors and officers of CIBC and its subsidiaries, in certain circumstances where CIBC is unable to provide indemnification to such directors and officers.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers or persons controlling the registrant pursuant to the foregoing provisions, the registrant 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.

Special Meetings of Shareholders

PrivateBancorp

PrivateBancorp's bylaws provide that special meetings of stockholders may be called by the Chairman of the Board, the President or the Secretary, and shall be called by the Chairman of the Board, the Chief Executive Officer or the Secretary at the request in writing of a majority of PrivateBancorp's board of directors.

CIBC

Under the Bank Act, special meetings of shareholders may be called at any time by the board of directors. In addition, subject to certain provisions of the Bank Act, the holders of not less than 5% of the issued and outstanding shares of CIBC that carry the right to vote at a meeting may request that the directors call a meeting of shareholders for the purpose stated in the request and may call the special meeting if the directors do not do so within 21 days after receiving the request.

Quorum Requirements

PrivateBancorp

PrivateBancorp's by-laws provide that the holders of a majority of the shares entitled to vote, represented in person or by proxy, shall constitute a quorum at any annual or special meeting of stockholders.

CIBC

The Bank Act permits a bank to establish by by-law the quorum requirement for meetings of shareholders. CIBC's by-laws provide that, a quorum for the transaction of business at any meeting of shareholders shall be at least two persons present in person, each being a shareholder entitled to vote thereat or a duly appointed proxyholder or representative for a shareholder so entitled, holding at least 25% of the shares entitled to vote at the meeting.

Shareholder Proposal and Director Nominations

PrivateBancorp

In order to properly bring business before any annual meeting as a PrivateBancorp stockholder, the stockholder must have the legal right and authority to make the proposal for consideration at the meeting and must have given timely notice of the proposal to the Chairman of the Board, the Chief Executive Officer or the Secretary. To be timely, the notice must be received by such person not less than 120 days prior to the meeting. However, in the event that less than 130 days' notice of the date of the meeting is given to stockholders, the stockholder's notice must be received no later than the close of business on the tenth day following the day on which notice of the meeting was mailed or public disclosure of the meeting date was made.

The stockholder's notice must set forth, as to each item of business the stockholder proposes to bring before the annual meeting: (a) a brief description of the business desired to be brought before the meeting, and in the case of a nomination for election of director, such nominee's name and qualifications, and the reasons for conducting business at the meeting, (b) the name and the record address of the stockholder or stockholders proposing such business, (c) the number of shares of stock of PrivateBancorp which are beneficially owned by such stockholder or stockholders, and (d) any material interest of the stockholder in such business.

CIBC

Under the Bank Act, any CIBC shareholder entitled to vote at an annual meeting of shareholders who for at least six months has been the registered holder or beneficial owner of the number of outstanding voting shares of CIBC (i) that is equal to 1% of the total number of voting shares outstanding or (ii) whose fair market value is at least C$2,000 may submit to CIBC notice of any matter that the shareholder proposes to raise at the meeting, and discuss at the meeting any matter in respect of which the shareholder would have been entitled to submit a proposal. If a proposal submitted to CIBC by a shareholder meets the conditions set out in the Bank Act, CIBC is required to include the proposal and, if requested, a statement by the shareholder in support of the proposal in its management proxy circular or to attach such information to its management proxy circular. The statement and the proposal together cannot exceed 500 words. CIBC is not subject to the SEC's rule on inclusion of shareholder proposals and supporting statements in its proxy materials.

A shareholder's proposal that includes nominations for the election of directors must be signed by one or more registered holders or beneficial owners of shares representing in the aggregate not less than 5% of the shares or 5% of the shares of a class of shares of CIBC entitled to vote at the meeting to which the proposal is to be presented.

Shareholder Action Without a Meeting

PrivateBancorp

PrivateBancorp shareholders have no right to take any action by written consent without a meeting.

CIBC

Under the Bank Act, shareholder action may be taken without a meeting by written resolution signed by all shareholders who would be entitled to vote on the matter at a meeting except in certain circumstances relating to the removal or replacement of a director or the auditor of CIBC. In the case of CIBC, as the Bank Act prohibits any person from being a major shareholder, the voting shares are widely held and it is unlikely that the signatures of all shareholders could be obtained in respect of any resolution.

Amendments of Governing Instruments

PrivateBancorp

In general, the certificate of incorporation may be amended by resolution of the board of directors and approved by (i) the holders of a majority of the outstanding shares entitled to vote thereon and (ii) a majority of the outstanding shares of each class entitled to a class vote thereon, if any. However, under the PrivateBancorp Certificate of Incorporation, the affirmative vote of the holders of at least two-thirds of the outstanding shares entitled to vote thereon is required to amend provisions related to the number of directors or the ability of stockholders to act by written consent.

Under Section 109 of Delaware law, the power to adopt, amend or repeal by-laws belongs to the stockholders; provided, however, that any corporation may, in its certificate of incorporation, confer such power also to its board of directors. The fact that such power has been so conferred upon the directors does not divest the stockholders of the power, nor limit their power to adopt, amend or repeal by-laws.

PrivateBancorp's certificate of incorporation confers the board of directors with the right to make, amend or repeal its by-laws.

CIBC

Under the Bank Act, the by-laws of a bank deal with the share capital of the bank and also regulate the business of affairs of the bank. The board of directors of CIBC may make, amend or repeal any bylaw that regulates the business or affairs of CIBC or in respect of the share capital of CIBC. The CIBC directors must submit a bylaw, or an amendment to or repeal of a bylaw, to the shareholders at the next meeting of shareholders, and the shareholders may, by resolution, confirm or amend the bylaw, amendment or repeal. Generally, a bylaw, or an amendment to or repeal of a bylaw, is effective from the date it is approved by directors until it is rejected or confirmed by the shareholders. However, changes with respect to the share capital by-laws (and changes to increase or decrease the number of directors or the minimum or maximum number of directors, a change to the bank's name or a change of province in which its home office is situated) must be approved by a special resolution passed at a shareholders' meeting with a majority of at least two-thirds of the votes cast at such meeting or by a resolution signed by all the shareholders entitled to vote on that resolution. Additionally, certain changes to the share capital by-laws entitle the holders of each class of shares (and each series of a class, if the shares of that series are affected differently by the amendment from other shares of that class) to vote separately as a class or series, with each share carrying the right to vote whether or not it otherwise carries the right to vote. Additionally, a change to the name of CIBC must also be approved by the Superintendent of Financial Institutions (Canada).

A shareholder entitled to vote at an annual meeting of shareholders of CIBC may make a proposal to make, amend or repeal a bylaw in accordance with the shareholder proposal requirements of the Bank Act.

Anti-Takeover and Ownership Provisions

PrivateBancorp

Banking Regulations. The Change in Bank Control Act of 1978 prohibits a person or group of persons who are acting in concert from acquiring "control" of a bank holding company (such as PrivateBancorp) unless (i) the acquisition has been approved by the Federal Reserve Board under the BHC Act or (ii) the Federal Reserve Board has been given 60 days' prior written notice of the proposed acquisition and within that time period the Federal Reserve Board has not issued a notice (a) disapproving the proposed acquisition or (b) extending for up to another 30 days the period during which such a disapproval may be issued. In addition, the Federal Reserve Board may extend the period for two additional periods not to exceed 45 days each in certain circumstances. Under a rebuttable presumption established by the Federal Reserve Board, the acquisition by a person or group of persons who are acting in concert of more than 10% of a class of voting stock of a bank holding company with a class of securities registered under Section 12 of the Securities Exchange Act (such as PrivateBancorp) would, under the circumstances set forth in the presumption, constitute the acquisition of control.

In addition, any entity that is a "company" as defined in the BHC Act would be required to obtain the approval of the Federal Reserve Board under the BHC Act before acquiring 25% (5% in the case of an acquirer that is a bank holding company) or more of the outstanding shares of PrivateBancorp common stock, or otherwise obtaining "control" over PrivateBancorp. Under the BHC Act, "control" generally means the ownership, control or power to vote 25% or more of any class of voting securities of the bank holding company, the ability to control in any manner the election of a majority of the bank holding company's directors or the ability, directly or indirectly, to exercise a controlling influence over the management and policies of the bank holding company, as determined by the Federal Reserve Board.

Delaware Law. Section 203 of the DGCL generally prevents a corporation from entering into a "Business Combination" with an "Interested Stockholder" for a period of three years following the time an Interested Stockholder becomes such, unless:

a. prior to such time the board of directors of the corporation has approved such Business Combination or the transaction in which an Interested Stockholder became such;

b. the transaction in which an Interested Stockholder became such resulted in such stockholder owning more than 85% of the corporation's voting stock (subject to certain exclusions); or

c. at or subsequent to the time of the transaction in which an Interested Stockholder becomes such, the Business Combination is approved by the board of directors of the corporation and authorized by ²/3 of the outstanding voting stock at an annual or special meeting (and not by written consent), excluding the stock owned by the Interested Stockholder.

Under Section 203 of the DGCL, "Business Combination" means, inter alia, (a) merger or consolidation with an Interested Stockholder, (b) sale, exchange or other disposition to or with an Interested Stockholder of 10% or more of the aggregate market value of either the assets on a consolidated basis or the outstanding stock of the corporation and (c) any receipt by an Interested Stockholder of financial benefits (except proportionately as a stockholder) by or through the corporation other than those expressly permitted by Delaware law. Holding company mergers authorized by Section 251(g) of the DGCL are excluded from the definition of "Business

132

Table of Contents

Combination." "Interested Stockholder" means any person or an affiliate of any such person (other than the corporation or any of its majority-owned subsidiaries) that beneficially (i) owns 15% or more of the outstanding voting stock of the corporation or (ii) owned 15% or more of the outstanding voting stock of the corporation at any time within the previous three years, subject to certain exceptions.

PrivateBancorp has not opted out of Section 203 of the DGCL.

CIBC

The Bank Act contains restrictions on the issue, transfer, acquisition, beneficial ownership and voting of all shares of a chartered bank. Subject to certain exceptions contained in the Bank Act, no person may be a major shareholder of CIBC or have a significant interest in any class of shares of CIBC. See "Description of CIBC Share Capital—Limitations Affecting Holders of CIBC Shares."

Rules and policies of certain Canadian securities regulatory authorities contain requirements in connection with "related party transactions." A related party transaction means, generally, any transaction by which an issuer (including CIBC), directly or indirectly, consummates one or more specified transactions with a related party, including purchasing or disposing of an asset, issuing securities and assuming liabilities. The term "related party" includes directors and senior officers of the issuer and holders of voting securities carrying, whether alone or acting jointly or in concert, more than 10% of the voting rights attaching to all issued and outstanding voting securities of the issuer or of a sufficient number of any securities of the issuer to materially affect control of the issuer.

Such rules and policies require more detailed disclosure in the proxy material provided to security holders in connection with a related-party transaction, and, subject to certain exceptions, the preparation of a formal valuation with respect to the subject matter of the related party transaction and any non-cash consideration offered in connection therewith and the inclusion of a summary of the valuation in the proxy material.

Such rules and policies also require that, subject to certain exceptions, an issuer must not engage in a related-party transaction unless approval of the disinterested shareholders of the issuer has been obtained.

The Bank Act prohibits CIBC from entering into any transaction with a related party unless the form of transaction is specifically permitted under the Bank Act. Permitted transactions must generally be on terms and conditions at least as favorable to CIBC as market terms and conditions. Under the Bank Act, related parties include the directors and senior officers of CIBC and their spouses and minor children and other entities with which they may control.

Appraisal and Dissenters' Rights

PrivateBancorp

Holders of PrivateBancorp common stock may, in certain situations, have appraisal or dissenters' rights under Section 262 of the DGCL in connection with a merger or consolidation. For additional information, see the section entitled "The Merger—Dissenters' Rights of Appraisal for Holders of PrivateBancorp Common Stock" beginning on page 99 of this proxy statement/prospectus.

CIBC

The only circumstance under which the Bank Act extends appraisal or dissenters' rights to shareholders is in respect of a compulsory acquisition of shares following a takeover bid through which an acquiror has acquired not less than 90% of the shares of the class that were the subject of the bid or as part of a going-private or squeeze-out transaction. Due to the ownership restrictions applicable to CIBC under the Bank Act, the shares of CIBC may not be the subject of a takeover bid, going private

133

Table of Contents

or squeeze-out transaction. See "Description of CIBC Share Capital—Limitations Affecting Holders of CIBC Shares."

Dividends and Other Distributions and Liquidation

PrivateBancorp

The PrivateBancorp board may, from time to time, authorize or declare dividends or other distributions in accordance with the DGCL.

Under Section 170 of the DGCL, the directors of every corporation, subject to any restrictions contained in its certificate of incorporation, may declare and pay dividends upon the shares of its capital stock either:

(1) out of its surplus; or

(2) in case there shall be no such surplus, out of its net profits for the fiscal year in which the dividend is declared and/or the preceding fiscal year.

CIBC

Under the Bank Act, holders of CIBC common shares are entitled to receive dividends declared on each CIBC common share held. The rates and amounts of preferential dividends attached to any series of Class A preferred shares or Class B preferred shares are fixed and set forth in the rights, privileges, restrictions and conditions attached to the respective series at the time of issuance of each series of Class A preferred shares or Class B preferred shares. The directors of CIBC may not declare, and CIBC may not pay, a dividend if there are reasonable grounds for believing that the payment would cause CIBC to be in contravention of the capital adequacy and liquidity regulations of the Bank Act or any guideline or direction of the Superintendent of Financial Institutions (Canada) respecting the maintenance of adequate capital and liquidity.

Under the Bank Act, CIBC may pay dividends in money or in property or by the issue of shares of CIBC or options or rights to acquire fully paid shares of CIBC. The directors of a bank shall notify the Superintendent of Financial Institutions (Canada) of the declaration of a dividend at least 15 days before the day fixed for its payment.

Under CIBC's by-laws, Class A preferred shares of each series are entitled to preference over Class B preferred shares and CIBC common shares, and Class B preferred shares of each series are entitled to preference over CIBC common shares with respect to the payment of dividends and the distribution of the assets of CIBC among its shareholders in the event of liquidation, dissolution or winding up of CIBC. See "Description of CIBC Shares."

CIBC MARKET ACTIVITIES INVOLVING CIBC COMMON SHARES

Since the announcement of the merger, CIBC and certain of its affiliates have engaged, and intend to continue to engage throughout the proxy solicitation period, in various market making, derivatives and structured notes hedging, brokerage and facilitation trading, asset management, index-related adjustments, investment fund management, plan-related activities, banking-related activities, estates and trusts services, custody-related activities and stock borrowing, lending and taking of collateral, involving CIBC common shares outside the United States (and, to a limited extent, within the United States). Among other things, CIBC or one or more of its affiliates intends to engage in trades in CIBC common shares and/or related derivatives for its own account and the accounts of its clients (and, to the extent described below, its employees) for the purpose of hedging their positions established in connection with the trading of certain derivatives relating to CIBC common shares, hedging CIBC's economic exposure arising from the issuance of structured notes, hedging CIBC's exposure in respect of positions in its market making obligations related to certain exchange traded funds, effecting brokerage transactions for its clients and other client facilitation transactions in respect of CIBC common shares, and effecting delivery of CIBC common shares as required pursuant to certain of CIBC's pension, benefit, incentive, compensation or other similar plans for employees. Further, certain of CIBC's asset management affiliates may buy and sell CIBC common shares, or ETFs, funds or indices including CIBC common shares, outside the United States (and, in the case of certain asset management activities, within the United States) as part of their ordinary, discretionary investment management activities on behalf of their clients or publicly traded funds managed by them. Certain of CIBC's affiliates may continue to (a) engage in the marketing and sale to clients of funds that include CIBC common shares, providing investment advice and financial planning guidance to clients that may include information about CIBC common shares, (b) transact in CIBC common shares as trustees and/or personal representatives of trusts and estates, (c) provide custody services relating to the CIBC

common shares, (d) engage in the borrowing and lending of CIBC common shares, as well as accepting CIBC common shares as collateral for loans, and (e) buy and sell CIBC common shares in connection with CIBC's normal course issuer bid. These activities occur both outside and inside the United States and the transactions in CIBC common shares may be effected on the TSX, the NYSE, other exchanges or alternative trading systems and in the over-the-counter market. The foregoing activities could have the effect of influencing the market price of CIBC common shares. CIBC has applied for certain exemptive relief from the SEC in relation to Regulation M under the Securities Exchange Act and from the Ontario Securities Commission in relation to OSC Rule 48-501—Trading During Distributions, Formal Bids And Share Exchange Transactions, in order to permit CIBC and certain of its affiliates to engage in the foregoing activities in the ordinary course during the proxy solicitation period.

VALIDITY OF CIBC COMMON SHARES

The validity of the CIBC common shares to be issued in connection with the merger has been passed upon for CIBC by Torys LLP (Toronto, Ontario, Canada). CIBC is being advised as to matters of U.S. law in respect of the merger by Mayer Brown LLP.

EXPERTS

The consolidated financial statements of PrivateBancorp, Inc. appearing in PrivateBancorp, Inc.'s Annual Report (Form 10-K) for the year ended December 31, 2015, and the effectiveness of PrivateBancorp, Inc.'s internal control over financial reporting as of December 31, 2015 have been audited by Ernst & Young LLP, independent registered public accounting firm, as set forth in their reports thereon, included therein, and incorporated herein by reference. Such consolidated financial statements are incorporated herein by reference in reliance upon such reports given on the authority of such firm as experts in accounting and auditing.

The consolidated financial statements of CIBC as at October 31, 2015 and 2014 and for the years ended October 31, 2015, 2014 and 2013 incorporated in this proxy statement/prospectus from CIBC's annual report on Form 40-F for the year ended October 31, 2015 and the effectiveness of internal control over financial reporting of CIBC as of October 31, 2015, have been audited by Ernst & Young LLP, an independent registered public accounting firm, as stated in their reports which are incorporated by reference. Such consolidated financial statements have been so incorporated herein by reference in reliance upon the reports given upon their authority as experts in accounting and auditing.

With respect to the unaudited condensed consolidated interim financial information of PrivateBancorp, Inc. for the three-month periods ended March 31, 2016 and March 31, 2015, and the three- and six-month periods ended June 30, 2016 and June 30, 2015, incorporated by reference in this Preliminary Prospectus, Ernst & Young LLP reported that they have applied limited procedures in accordance with professional standards for a review of such information. However, their separate reports dated May 5, 2016, and August 8, 2016, included in PrivateBancorp, Inc.'s Quarterly Report on Form 10-Q for the quarters ended March 31, 2016, and June 30, 2016, respectively, and incorporated by reference herein, states that they did not audit and they do not express an opinion on that interim financial information. Accordingly, the degree of reliance on their report on such information should be restricted in light of the limited nature of the review procedures applied. Ernst & Young LLP is not subject to the liability provisions of Section 11 of the Securities Act of 1933 (the "Act") for their report on the unaudited interim financial information because that report is not a "report" or a "part" of the Registration Statement prepared or certified by Ernst & Young LLP within the meaning of Sections 7 and 11 of the Act.

The written proposal must contain certain information about the proposal and the shareholder making the proposal and otherwise comply with the procedures set forth in the Bank Act.

WHEREAS, for Federal income tax purposes, it is intended that the Merger shall qualify as a "reorganization" within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended (the "Code"), and this Agreement is intended to be and is adopted as a plan of reorganization for purposes of Sections 354 and 361 of the Code;

WHEREAS, as an inducement to and condition of Parent's willingness to enter into this Agreement, concurrently with the entry of the parties into this Agreement, Larry D. Richman is entering into an employment agreement with Parent; and

WHEREAS, the parties desire to make certain representations, warranties and agreements in connection with the Merger and also to prescribe certain conditions to the Merger.

NOW, THEREFORE, in consideration of the mutual covenants, representations, warranties and agreements contained herein, and intending to be legally bound hereby, the parties agree as follows:

ARTICLE I

THE MERGER

1.1 The Merger. Subject to the terms and conditions of this Agreement, in accordance with the Delaware General Corporation Law (the "DGCL"), at the Effective Time, Company shall merge with and into Holdco. Holdco shall be the Surviving Corporation in the Merger, and shall continue its corporate existence under the laws of the State of Delaware. Upon consummation of the Merger, the separate corporate existence of Company shall terminate.

1.2 Closing. Subject to the terms and conditions of this Agreement, the closing of the Merger (the "Closing") will take place at 10:00 a.m., New York City time, at the offices of Mayer Brown LLP, on a date which shall be no later than three (3) business days after the satisfaction or waiver (subject to applicable law) of the latest to occur of the conditions set forth in Article VII hereof (other than those conditions that by their nature can only be satisfied at the Closing, but subject to the satisfaction or waiver thereof) unless another date, time or place is agreed to in writing by Parent and Company. The date on which the Closing occurs is referred to in this Agreement as the "Closing Date".

1.3 Effective Time. Subject to the terms and conditions of this Agreement, on or before the Closing Date, Parent shall cause to be filed with the Secretary of State of the State of Delaware (the "Delaware Secretary") a certificate of merger (the "Certificate of Merger"), as provided in Section 251 of the DGCL.

1.4 Effects of the Merger. At and after the Effective Time, the Merger shall have the effects set forth in the applicable provisions of the DGCL.

1.5 Conversion of Company Common Stock. At the Effective Time, by virtue of the Merger and without any action on the part of Parent, Holdco, Company or the holder of any of the following securities:

(a) Each share of the common stock, without par value, of Company issued and outstanding immediately prior to the Effective Time (the "Company Common Stock") (except for (x) shares of Company Common Stock owned by Company as treasury stock or owned by Company or Parent (in each case other than shares of Company Common Stock (A) held in any Company Benefit Plans or related trust accounts, managed accounts, mutual funds and the like, or otherwise held in a fiduciary or agency capacity or (B) held, directly or indirectly, in respect of a debt previously contracted (collectively, the "Exception Shares")), (y) Dissenting Shares and (z) Company Restricted Share Awards) shall be converted, in accordance with the procedures set forth in this Agreement, into the right to receive without interest, (i) 0.3657 common shares (the "Exchange Ratio") of Parent (the "Parent Common Shares") and (ii) $18.80 in cash (the "Per Share Cash Consideration") (the consideration described in clauses (i) and (ii), the "Merger Consideration").

(b) All the shares of Company Common Stock converted into the right to receive the Merger Consideration pursuant to this Article I shall no longer be outstanding and shall automatically be cancelled and shall cease to exist as of the Effective Time, and each certificate (each, an "Old Certificate", it being understood that any reference herein to "Old Certificate" shall be deemed to include reference to book-entry account statements relating to the ownership of shares of Company Common Stock) previously representing any such shares of Company Common Stock shall thereafter represent only the right to receive (i) the Merger Consideration, (ii) cash in lieu of fractional shares which the shares of Company Common Stock represented by such Old Certificate have been converted into the right to receive pursuant to this Section 1.5 and Section 2.3(e), without any interest thereon, and (iii) any dividends or distributions which the holder thereof has the right to receive pursuant to Section 2.3(b). If, prior to the Effective Time, the outstanding Parent Common Shares shall have been increased, decreased, or changed into or exchanged for a different number or kind of shares or securities, in any such case as a result of a reorganization, recapitalization, reclassification, stock dividend, stock split, reverse stock split, or other similar change in capitalization, or there shall be any extraordinary dividend or distribution, an appropriate and proportionate adjustment shall be made to the Merger Consideration to give holders of Company Common Stock the same economic effect as contemplated by this Agreement prior to such event.

(c) Notwithstanding anything in this Agreement to the contrary, at the Effective Time, all shares of Company Common Stock that are owned by Company or Parent (in each case other than the Exception Shares) shall be cancelled and shall cease to exist and neither the Merger Consideration nor any other consideration shall be delivered in exchange therefor.

1.6 Parent Common Shares. At and after the Effective Time, each Parent Common Share issued and outstanding immediately prior to the Effective Time shall remain an issued and outstanding share of common stock of the Parent and shall not be affected by the Merger.

1.7 Surviving Corporation Common Stock.

1.8 Treatment of Company Equity Awards.

(a) At the Effective Time, each option to purchase shares of Company Common Stock granted by Company under a Company Stock Plan (as defined below) that is outstanding and unexercised immediately prior to the Effective Time (a "Company Stock Option") shall be converted automatically into an option (an "Adjusted Stock Option") to purchase, on the same terms and conditions as were applicable under such Company Stock Option immediately prior to the Effective Time (including vesting terms), the number of Parent Common Shares (rounded down to the nearest whole number of shares) equal to the product of (i) the number of shares of Company Common Stock subject to such Company Stock Option immediately prior to the Effective Time, multiplied by (ii) the sum of (A) the Exchange Ratio and (B) the quotient (rounded to four decimal places) obtained by dividing (x) the Per Share Cash Consideration by (y) the Parent Share Closing Price (clause (ii) hereof, the "Equity Award Exchange Ratio"), which Adjusted Stock Option shall have an exercise price per Parent Common Share equal to the quotient (rounded up to the nearest whole cent) obtained by dividing (1) the exercise price per share of Company Common Stock subject to such Company Stock Option immediately prior to the Effective Time, by (2) the Equity Award Exchange Ratio. For purposes of this Agreement, "Company Stock Plans" means the Company Incentive Compensation Plan, the Company Strategic Long-Term Incentive Plan, the Company 2007 Long-Term Incentive Compensation Plan, and the Company Amended and Restated 2011 Incentive Compensation Plan.

(b) At the Effective Time, each award of shares of Company Common Stock subject to vesting, repurchase or other lapse restriction granted under a Company Stock Plan that is outstanding and unvested immediately prior to the Effective Time (a "Company Restricted Stock Award") shall be cancelled and replaced with a restricted stock award of Parent Common Shares (an "Adjusted Restricted Stock Award") with the same terms and conditions as were applicable under such Company Restricted Stock Award immediately prior to the Effective Time (including vesting terms), and relating to the number of Parent Common Shares equal to the product of (i) the number of shares of Company Common Stock subject to such Company Restricted Stock Award immediately prior to the Effective Time, multiplied by (ii) the Equity Award Exchange Ratio, with any fractional shares rounded to the next whole number of shares.

(c) At the Effective Time, each restricted stock unit award in respect of shares of Company Common Stock granted under a Company Stock Plan that is outstanding immediately prior to the Effective Time (a "Company Restricted Stock Unit Award") shall (i) if unvested, be converted automatically into a cash-settled restricted stock unit award (an "Adjusted Restricted Stock Unit Award") with the same terms and conditions as were applicable under such Company Restricted Stock Unit Award immediately prior to the Effective Time (including vesting terms), except that settlement shall be in the form of a cash payment equal to the fair market value (determined under the methodology used by Parent for determining fair market value for employee equity awards generally) of the Parent Common Shares to which the award relates, and relating to the number of Parent Common Shares equal to the product (taken to the fourth decimal place) of (A) the number of shares of Company Common Stock subject to such Company Restricted Stock Unit Award immediately prior to the Effective Time, multiplied by (B) the Equity Award Exchange Ratio, or (ii) if vested (including for this purpose all Company Restricted Stock Unit Awards held by non-employee directors, whether or not vested as of date hereof, all of which shall be vested and settled within ten (10) days after the Effective Time pursuant to this clause (ii)), be cancelled and converted automatically into the right to receive, as soon as reasonably practicable (but not later than ten (10) days) after the Effective Time, (A) a cash payment equal to the sum of (1) the Per Share Cash Consideration plus (2) the product of the Exchange Ratio multiplied by the Parent Share Closing Price (such sum, the "Per Unit Total Consideration") (without interest and less applicable Tax withholding) in respect of each share of Company Common Stock underlying

such Company Restricted Stock Unit Award and (B) a cash payment equal to all dividend equivalents accumulated with respect to such Company Restricted Stock Unit Award that have not been paid prior to the Effective Time; provided, that if the terms of any such vested Company Restricted Stock Unit Award do not provide for settlement upon a change in control, such vested Company Restricted Stock Unit Award shall instead be converted into an Adjusted Restricted Stock Unit Award pursuant to clause (i) above and shall be settled at the earliest time provided by its terms as is consistent with Section 409A of the Code. For purposes of the preceding sentence, each vested Company Restricted Stock Unit Award for which settlement was delayed for the purpose of avoiding a loss of deduction pursuant to Section 162(m) of the Code shall be treated as providing for settlement upon a change in control.

(d) At the Effective Time, each performance share unit award in respect of shares of Company Common Stock granted under a Company Stock Plan that is outstanding immediately prior to the Effective Time (a "Company Performance Share Unit Award") shall (i) if unvested, be converted automatically into a cash-settled restricted stock unit award (an "Adjusted Performance Share Unit Award") with the same terms and conditions as were applicable under such Company Performance Share Unit Award immediately prior to the Effective Time (except that such Adjusted Performance Share Unit Award shall be subject solely to time based vesting and settlement shall be in the form of a cash payment equal to the fair market value (determined under the methodology used by Parent for determining fair market value for employee equity awards generally) of the Parent Common Shares to which the award relates), and relating to the number of Parent Common Shares equal to the product (taken to the fourth decimal place) of (A) the number of shares of Company Common Stock subject to such Company Performance Share Unit Award immediately prior to the Effective Time, multiplied by (B) the Equity Award Exchange Ratio, or (ii) if vested, be cancelled and converted automatically into the right to receive, as soon as reasonably practicable (but not later than ten (10) days) after the Effective Time, (A) a cash payment equal to the Per Unit Total Consideration (without interest and less applicable Tax withholding) in respect of each share of Company Common Stock underlying such Company Performance Share Unit Award and (B) a cash payment equal to all dividend equivalents accumulated with respect to such Company Performance Share Unit Award that have not been paid prior to the Effective Time; provided, that if the terms of any such vested Company Performance Share Unit Award do not provide for settlement upon a change in control, such vested Company Performance Share Unit Award shall instead be converted into an Adjusted Performance Share Unit Award pursuant to clause (i) above and shall be settled at the earliest time provided by its terms as is consistent with Section 409A of the Code. For all purposes of this Section 1.8(d), the number of shares of Company Common Stock subject to each Performance Share Unit Award that was granted in 2014, 2015 or 2016 that is outstanding immediately prior to the Effective Time shall be determined by assuming that the applicable performance goals have been achieved at the maximum level.

DELIVERY OF MERGER CONSIDERATION

2.1 Exchange Agent. Prior to the Effective Time, Parent shall deposit, or shall cause to be deposited by Holdco, with a bank or trust company designated by Parent and reasonably acceptable to Company (the "Exchange Agent"), for the benefit of the holders of Old Certificates, for exchange in accordance with this Article II, (a) certificates, or at Parent's option, evidence of shares in book entry form, representing the Parent Common Shares ("New Certificates"), to be delivered to the holders of Company Common Stock pursuant to Section 1.5 and this Article II in exchange for outstanding shares of such Company Common Stock, and (b) cash in an amount sufficient to allow the Exchange Agent to make all payments required pursuant to this Article II (such New Certificates and cash, together with any dividends or distributions with respect thereto, being hereinafter referred to as the "Exchange Fund"). The Exchange Agent shall invest any cash included in the Exchange Fund as directed by Parent, provided that no such investment or losses thereon shall affect the amount of Merger

A-5

Table of Contents

Consideration payable to the holders of Old Certificates. Any interest and other income resulting from such investments shall be paid to Parent or Holdco, or as otherwise directed by Parent.

2.2 Appraisal Rights. Each issued and outstanding share of Company Common Stock the holder of which has perfected his right to dissent under the DGCL and has not effectively withdrawn or lost such right as of the Effective Time (the "Dissenting Shares") shall not be converted into or represent a right to receive the Merger Consideration hereunder, and the holder thereof shall be entitled only to such rights as are granted by the DGCL. Company shall give Parent prompt notice upon receipt by Company of any such demands for payment of the fair value of such shares of Company Common Stock, any withdrawals of such notice and any other instruments provided pursuant to applicable law (any stockholder duly making such demand being hereinafter called a "Dissenting Stockholder"). Company shall not, except with the prior written consent of Parent, voluntarily make any payment with respect to, or settle or offer to settle, any such demand for payment, or waive any failure to timely deliver a written demand for appraisal or the taking of any other action by such Dissenting Stockholder as may be necessary to perfect appraisal rights under the DGCL. Company shall give Parent the opportunity to participate in and direct all negotiations and proceedings with respect to any such demands. Any payments made in respect of Dissenting Shares shall be made by the Surviving Corporation. If any Dissenting Stockholder shall effectively withdraw or lose (through failure to perfect or otherwise) his, her or its right to such payment at or prior to the Effective Time, such holder's shares of Company Common Stock shall be converted into a right to receive the Merger Consideration in accordance with Section 1.5(a).

2.3 Exchange Procedures.

(a) As promptly as practicable after the Effective Time, but in no event later than ten (10) days thereafter, Parent shall cause the Exchange Agent to mail to each person who was, immediately prior to the Effective Time, a holder of record of one or more Old Certificates representing shares 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 the Old Certificates shall pass, only upon proper delivery of the Old Certificates to the Exchange Agent) and instructions for use in effecting the surrender of the Old Certificates in exchange for certificates representing the number of whole Parent Common Shares, any cash in lieu of fractional shares and the cash portion of the Merger Consideration which the shares of Company Common Stock represented by such Old Certificate or Old Certificates shall have been converted into the right to receive pursuant to this Agreement as well as any dividends or distributions to be paid in respect thereof pursuant to Section 2.3(b). From and after the Effective Time, upon proper surrender of an Old Certificate or Old Certificates for exchange and cancellation to the Exchange Agent, together with such properly completed letter of transmittal, duly executed, the holder of such Old Certificate or Old Certificates shall be entitled to receive in exchange therefor, subject to Section 2.2, (i) a New Certificate representing that number of whole Parent Common Shares to which such holder of Company Common Stock shall have become entitled pursuant to the provisions of Article I and (ii) a check representing the amount of (A) the cash portion of the Merger Consideration which such holder has the right to receive in respect of the Old Certificate or Old Certificates surrendered pursuant to the provisions of this Article II, (B) any cash in lieu of a fractional share which such holder has the right to receive in respect of the Old Certificate or Old Certificates surrendered pursuant to the provisions of this Article II, and (C) and dividends or distributions that the holder presenting such Old Certificates is entitled to, as provided in this Article II, and the Old Certificate or Old Certificates so surrendered shall forthwith be cancelled. No interest will be paid or accrued with respect to any property to be delivered upon surrender of Old Certificates. Until surrendered as contemplated by this Section 2.3, each Old Certificate shall be deemed at any time after the Effective Time to represent only the right to receive, upon surrender, the Merger

A-6

Table of Contents

Consideration and any cash in lieu of fractional shares or in respect of dividends or distributions as contemplated by this Section 2.3.

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

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

(d) After the Effective Time, there shall be no transfers on the stock transfer books of Company of the shares of Company Common Stock that were issued and outstanding immediately prior to the Effective Time.

(e) Notwithstanding anything to the contrary contained herein, no New Certificates or scrip representing fractional Parent Common Shares shall be issued upon the surrender for exchange of Old Certificates, no dividend or distribution with respect to Parent Common Shares shall be payable on or with respect to any fractional share, and such fractional share interests shall not entitle the owner thereof to vote or to any other rights of a shareholder of Parent. In lieu of the issuance of any such fractional share, Parent shall pay to each former stockholder of Company who otherwise would be entitled to receive such fractional share an amount in cash (rounded to the nearest cent) determined by multiplying (i) the volume-weighted average trading price of one Parent Common Share for the ten (10) day period in which both the Canadian and U.S. Markets are open for trading ending on the last such day immediately preceding the Closing Date, calculated using both Canadian and U.S. trading prices and volumes during normal market hours and assuming in respect of such trading prices on the TSX, for each trading day, the Bank of Canada daily noon Canada/U.S. exchange rate for the Canadian calculations (the "Parent Share Closing Price") by (ii) the fraction of a Parent Common Share (rounded to the nearest thousandth when expressed in decimal form) to which such holder would otherwise be entitled (after taking into account all shares of Company Common Stock owned by such holder as of immediately prior to the Effective Time).

(f) Any portion of the Exchange Fund that remains unclaimed by the stockholders of Company for one (1) year after the Effective Time shall be paid to the Surviving Corporation. Any former stockholders of Company who have not theretofore exchanged their Old Certificates pursuant to this Article II shall thereafter look only to the Surviving Corporation for payment of the Merger Consideration, cash in lieu of any fractional shares and any unpaid dividends and distributions on the Parent Common Shares deliverable in respect of each former share of Company Common Stock such stockholder holds as determined pursuant to this Agreement, in each case, without any interest thereon. Notwithstanding the foregoing, none of Parent, Company, the Surviving Corporation, the Exchange Agent or any other person shall be liable to any former holder of shares of Company Common Stock for any amount delivered in good faith to a public official pursuant to applicable abandoned property, escheat or similar laws.

(g) Parent shall be entitled to deduct and withhold, or cause Holdco, Company or the Exchange Agent to deduct and withhold, from the cash portion of the aggregate Merger Consideration, any cash in lieu of fractional Parent Common Shares, cash dividends or distributions payable pursuant to this Section 2.3 or any other cash amounts otherwise payable pursuant to this Agreement to any holder of Company Common Stock such amounts as it is required to deduct and withhold with respect to the making of such payment under the Code or any provision of state, local or foreign Tax law. To the extent that amounts are so withheld by Parent, Holdco, Company or the Exchange Agent, as the case may be, and paid over to the appropriate governmental authority, the withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of Company Common Stock in respect of which the deduction and withholding was made by Parent, Holdco, Company or the Exchange Agent, as the case may be.

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

Without limiting the generality of the foregoing, as soon as practicable and in no event later than forty (40) days after the date of this Agreement, Parent and Company shall, and shall cause their respective Subsidiaries to, each prepare and file any applications, notices and filings required in order to obtain the Requisite Regulatory Approvals. Parent and Company shall each use, and shall each cause their applicable Subsidiaries to use, reasonable best efforts to obtain each such Requisite Regulatory Approval as promptly as reasonably practicable. The parties shall cooperate with each other in connection therewith (including the furnishing of any information and any reasonable undertaking or commitments that may be required to obtain the Requisite Regulatory Approvals). Parent and Company shall have the right to review in advance, and, to the extent practicable, each will consult the other on, in each case subject to applicable laws relating to the exchange of information, all the information relating to Company or Parent, as the case may be, and any of their respective Subsidiaries, which appears in any filing made with, or written materials submitted to, any third party or any Governmental Entity in connection with the transactions contemplated by this Agreement. In exercising the foregoing right, each of the parties hereto shall act reasonably and as promptly as practicable. Each party will provide the other with copies of any applications and all correspondence relating thereto prior to filing, other than any portions of material filed in connection therewith that contain competitively sensitive business or other proprietary information filed under a claim of confidentiality and subject to applicable laws relating to the exchange of information. The parties hereto agree that they will consult with each other with respect to the obtaining of all permits, consents, approvals and authorizations of all third parties and Governmental Entities necessary or advisable to consummate the transactions contemplated by this Agreement, and each party will keep the other apprised of the status of matters relating to completion of the transactions contemplated herein.

(c) In furtherance and not in limitation of the foregoing, each of Parent and Company shall use its reasonable best efforts to avoid the entry of, or to have vacated, lifted, reversed or overturned any decree, judgment, injunction or other order, whether temporary, preliminary or permanent, that would restrain, prevent or delay the Closing. Notwithstanding anything to the contrary in this Agreement, nothing contained in this Agreement shall require Parent or Company to take, or commit to take, any action or agree to any condition or restriction that would reasonably be likely to have a material and adverse effect on Parent and its Subsidiaries, taken as a whole, giving effect to the Merger (with such materiality measured on a scale relative to Company and its Subsidiaries, taken as a whole) (a "Materially Burdensome Regulatory Condition").

(d) Parent and Company shall, upon request, furnish each other with all information to which they have access concerning themselves, their Subsidiaries, directors, officers and shareholders and such other matters as may be reasonably necessary or advisable in connection with the Proxy Statement, the F-4 or any other statement, filing, notice or application made by or on behalf of Parent, Company or any of their respective Subsidiaries to any Governmental Entity in connection with the Merger and the other transactions contemplated by this Agreement. Each of Parent and Company agrees, as to itself and its Subsidiaries, (i) that none of the information supplied or to be supplied by it for inclusion or incorporation by reference in the F-4 will, at the time the F-4 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 (ii) that none of the information supplied or to be supplied by it for inclusion or incorporation by reference in the Proxy Statement and any amendment or supplement thereto will, at the date of mailing to shareholders 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 light of the circumstances under which such statement was made, not misleading. Each of Parent and Company further agrees that if it becomes aware that any information furnished by it would cause any of the statements in the F-4 or the Proxy 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 F-4 or the Proxy Statement.

(e) Parent and Company shall promptly advise each other upon receiving any communication from any Governmental Entity whose consent or approval is required for consummation of the transactions contemplated by this Agreement that causes such party to believe that there is a reasonable likelihood that any Requisite Regulatory Approval will not be obtained or that the receipt of any such approval will be materially delayed.

(f) Parent shall, and shall cause the Surviving Company to, comply with the "reporting requirements" of Treasury Regulations Section 1.367(a)-3(c)(6).

6.2 Access to Information.

(a) Upon reasonable notice and subject to applicable laws, Company shall, and shall cause each of its Subsidiaries to, afford to the officers, employees, accountants, counsel, advisors and other representatives of Parent reasonable access, during normal business hours during the period prior to the Effective Time, to all its properties, books, contracts, personnel, information technology systems and records, and each shall reasonably cooperate with Parent in preparing to execute after the Effective Time conversion or consolidation of systems and business operations generally (including by entering into customary confidentiality, nondisclosure and similar agreements with service providers), and, during such period, Company shall, and shall cause its Subsidiaries to, make available to Parent such information concerning its business, properties and personnel as Parent may reasonably request. Parent shall use commercially reasonable efforts to

A-38

Table of Contents

minimize any interference with Company's regular business operations during any such access. Upon reasonable notice and subject to applicable laws, Parent shall, and shall cause each of its Subsidiaries to, furnish or otherwise make available to the officers, employees, accountants, counsel, advisors and other representatives of Company such information concerning its businesses as is reasonably relevant to Company and its stockholders in connection with the transactions contemplated by this Agreement. No party shall be required to provide access to or to disclose information where such access or disclosure would jeopardize the attorney-client privilege of the institution in possession or control of such information (after giving due consideration to the existence of any common interest, joint defense or similar agreement between the parties) or contravene any law, rule, regulation, order, judgment, decree, fiduciary duty or binding agreement entered into prior to the date of this Agreement. The parties hereto will make appropriate substitute disclosure arrangements under circumstances in which the restrictions of the preceding sentence apply.

(b) Each party shall hold all information furnished by or on behalf of it or any of its Subsidiaries or representatives pursuant to Section 6.2(a) in confidence to the extent required by, and in accordance with, the provisions of the confidentiality agreement, dated April 25, 2016, by and between Parent and Company (the "Confidentiality Agreement"); provided that, as of the date of this Agreement, Sections 13 and 15 of the Confidentiality Agreement shall terminate and no longer be in effect.

(c) No investigation by Parent, Company or their respective representatives pursuant to this Section 6.2 or prior to the date of this Agreement shall affect or be deemed to modify or waive the representations and warranties of the other set forth herein. Nothing contained in this Agreement shall give either Parent or Company, directly or indirectly, the right to control or direct the operations of the other party prior to the Effective Time. Prior to the Effective Time, each party shall exercise, consistent with the terms and conditions of this Agreement, complete control and supervision over its and its Subsidiaries' respective operations.

6.3 Company Stockholder Approval.

(a) Company shall take, in accordance with applicable law and the Company Certificate and Company Bylaws, all action necessary to convene a meeting of its stockholders (the "Company Meeting") to be held as soon as reasonably practicable after the F-4 is declared effective for the purpose of obtaining the Requisite Company Vote required in connection with this Agreement and the Merger, and, if so desired and mutually agreed, upon other matters of the type customarily brought before an annual or special meeting of stockholders to adopt a merger agreement. The Board of Directors of Company shall use its reasonable best efforts to obtain from the stockholders of Company the Requisite Company Vote, including by communicating to its stockholders its recommendation (and including such recommendation in the Proxy Statement) that they adopt and approve this Agreement and the transactions contemplated hereby. Company shall engage a proxy solicitor reasonably acceptable to Parent to assist in the solicitation of proxies from stockholders relating to the Requisite Company Vote. However, subject to Sections 8.1 and 8.2, if the Board of Directors of Company, after receiving the advice of its outside counsel and, with respect to financial matters, its financial advisors, determines in good faith that, because of the receipt by Company of an Acquisition Proposal that the Board of Directors of Company concludes in good faith constitutes a Superior Proposal, it would violate its fiduciary duties under applicable law to continue to recommend this Agreement, then in submitting this Agreement to its stockholders, the Board of Directors of Company may 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 Board of Directors of Company may communicate the basis for its lack of a recommendation to its stockholders in the Proxy Statement or an appropriate amendment or supplement thereto to the extent required by law; provided that

A-39

Table of Contents

the Board of Directors of Company may not take any actions under this sentence unless (i) it gives Parent at least four (4) business days' prior written notice of its intention to take such action and a reasonable description of the event or circumstances giving rise to its determination to take such action (including, in the event such action is taken by the Board of Directors of Company in response to an Acquisition Proposal, the latest material terms and conditions and the identity of the third party in any such Acquisition Proposal, or any amendment or modification thereof, or describe in reasonable detail such other event or circumstances) and (ii) at the end of such notice period, the Board of Directors of Company takes into account any amendment or modification to this Agreement proposed in writing by Parent and after receiving the advice of its outside counsel and, with respect to financial matters, its financial advisors, determines in good faith that it would nevertheless more likely than not result in a violation of its fiduciary duties under applicable law to continue to recommend this Agreement. Any material amendment to any Acquisition Proposal will be deemed to be a new Acquisition Proposal for purposes of this Section 6.3 and will require a new notice period as referred to in this Section 6.3.

(b) Company shall adjourn or postpone the Company Meeting (i) if, as of the time for which such meeting is originally scheduled, there are insufficient shares of Company Common Stock represented (either in person or by proxy) to constitute a quorum necessary to conduct the business of such meeting, or (ii) if, on the date of such meeting, Company has not received proxies representing a sufficient number of shares necessary to obtain the Requisite Company Vote. Notwithstanding anything to the contrary herein, unless this Agreement has been terminated in accordance with its terms, the Company Meeting shall be convened and this Agreement shall be submitted to the stockholders of Company at the Company Meeting, for the purpose of voting on the adoption of this Agreement and the other matters contemplated hereby, and nothing contained herein shall be deemed to relieve Company of such obligation.

comparable in the aggregate to those provided to such employees by Company and its Subsidiaries immediately prior to the Effective Time. In addition, Parent agrees that, for each Continuing Employee, the terms and conditions of (A) the annual long-term incentive awards granted in respect of calendar year 2016 to be granted in the first quarter of 2017, (B) the 2017 annual short-term incentive award and (C) to the extent applicable, mandatory 2016 annual bonus deferrals, shall, in each case, be consistent with the terms described on Section 6.6(a) of the Company Disclosure Schedule.

(b) With respect to any employee benefit plans of Parent or its Subsidiaries in which any employees of Company or its Subsidiaries become eligible to participate on or after the Effective Time (the "New Plans"), Parent shall or shall cause the Surviving Corporation to:

(i) use commercially reasonable efforts to (A) waive all pre-existing conditions, exclusions and waiting periods with respect to participation and coverage requirements applicable to each such employee and his or her eligible dependents under any New Plans, except to the extent such pre-existing conditions, exclusions or waiting periods would apply under the analogous Company Benefit Plan, and (B) provide each such employee and his or her eligible dependents with credit for any co-payments or deductibles paid prior to the Effective Time under a Company Benefit Plan (to the same extent that such credit was given under the analogous Company Benefit Plan prior to the Effective Time) in satisfying any applicable deductible or out-of-pocket requirements under any New Plans; and

(ii) recognize all service of each such employee with Company and its Subsidiaries (and their respective predecessors, if applicable) for all purposes in any New Plan; provided that the foregoing service recognition shall not apply (A) to the extent it would result in duplication of benefits for the same period of services, (B) for purposes of any defined benefit pension plan or benefit plan that provides retiree welfare benefits, or (C) to any benefit plan that is a frozen plan or provides grandfathered benefits.

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

A-41

director or consultant of Company or any of its Subsidiaries or affiliates, any right, benefit or remedy of any nature whatsoever under or by reason of this Agreement.

6.7 Indemnification; Directors' and Officers' Insurance.

(a) From and after the Effective Time, Parent shall cause the Surviving Corporation to indemnify and hold harmless each present and former director, officer or employee of Company and its Subsidiaries or fiduciaries of Company or any of its Subsidiaries under Company Benefit Plans (in each case, when acting in such capacity) (collectively, the "Company Indemnified Parties") against any costs or expenses (including reasonable attorneys' fees), judgments, fines, losses, damages or liabilities incurred in connection with any threatened or actual claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative, whether arising before or after the Effective Time, arising in whole or in part out of (i) the fact that such person is or was a director, officer or employee of Company or any Company Subsidiary or is or was a fiduciary of Company or any of its Subsidiaries under Company Benefit Plans or (ii) matters, acts or omissions existing or occurring at or prior to the Effective Time, including the transactions contemplated hereby to the same extent as such persons are indemnified as of the date of this Agreement by Company pursuant to the Company Certificate, the Company Bylaws, the governing or organizational documents of any Company Subsidiary and any indemnification agreements in existence as of the date hereof; and Parent shall also cause the Surviving Corporation to 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 Company pursuant to the Company Certificate, the Company Bylaws, the governing or organizational documents of any Company Subsidiary and any indemnification agreements in existence as of the date hereof; provided that the Company Indemnified Party to whom expenses are advanced provides an undertaking (in a reasonable and customary form) to repay such advances if it is ultimately determined that such Company Indemnified Party is not entitled to indemnification.

(b) Subject to the following sentence, for a period of six (6) years after the Effective Time, Parent shall cause to be maintained in effect the current policies of directors' and officers' liability insurance maintained by Company (provided, that the Surviving Corporation may substitute therefor policies with a substantially comparable insurer of at least the same coverage and amounts containing terms and conditions which are no less advantageous to the insured) with respect to claims against the present and former officers and directors of Company or any of its Subsidiaries arising from facts or events which occurred at or before the Effective Time (including the transactions contemplated by this Agreement); provided, however, that the Surviving Corporation shall not be obligated to expend, on an annual basis, an amount in excess of 300% of the aggregate annual premium paid as of the date hereof by Company for such insurance (the "Premium Cap"), and if such premiums for such insurance would at any time exceed the Premium Cap, then the Surviving Corporation shall cause to be maintained policies of insurance which, in the Surviving Corporation's good faith determination, provide the maximum coverage available at an annual premium equal to the Premium Cap. In lieu of the foregoing, Company, in consultation with Parent may (and at the request of Parent, Company shall use its reasonable best efforts to) obtain at or prior to the Effective Time a six-year "tail" policy under Company's existing directors and officers insurance policy providing equivalent coverage to that described in the preceding sentence if and to the extent that the same may be obtained for an amount that, in the aggregate, does not exceed the Premium Cap (it being understood that any failure by Company to obtain such a "tail" policy shall not modify or alter in any manner any of the obligations of Parent or the Surviving Corporation under this Section 6.7).

(c) The provisions of this Section 6.7 shall survive the Effective Time and are intended to be for the benefit of, and shall be enforceable by, each Company Indemnified Party and his or her heirs and representatives. If the Surviving Corporation, or any of its successors or assigns,

A-42

consolidates with or merges into any other entity and is not the continuing or surviving entity of such consolidation or merger, transfers all or substantially all of its assets or deposits to any other entity or engages in any similar transaction, then in each case, the Surviving Corporation will cause proper provision to be made so that the successors and assigns of the Surviving Corporation will expressly assume the obligations set forth in this Section 6.7.

6.8 Additional Agreements. In case at any time after the Effective Time any further action is necessary or desirable to carry out the purposes of this Agreement or to vest the Surviving Corporation with full title to all properties, assets, rights, approvals, immunities and franchises of any of the parties to the Merger, each party to this Agreement and their respective Subsidiaries shall take, or cause to be taken, all such necessary action as may be reasonably requested by any other party, at the expense of the party who makes any such request.

6.9 Advice of Changes. Each of Parent and Company shall promptly advise the other of any fact, change, event or circumstance known to it (i) that has had or is reasonably likely to have a Material Adverse Effect on it or (ii) 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 or that reasonably could be expected to give rise, individually or in the aggregate, to the failure of a condition in Article VII; provided, that any failure to give notice in accordance with the foregoing shall not be deemed to constitute a violation of this Section 6.9, provide a basis for terminating this Agreement or constitute the failure of any condition set forth in Article VII to be satisfied, or otherwise constitute a breach of this Agreement by the party failing to give such notice, in each case unless the underlying fact, change, event or circumstance would independently result in a failure of the conditions set forth in Article VII to be satisfied or provide a basis for terminating this Agreement or constitute a breach of this Agreement.

6.10 Acquisition Proposals.

(a) Company shall not, and shall cause its Subsidiaries not to, and shall use its reasonable best efforts to cause its and their officers, directors, agents, advisors and representatives (collectively, "Representatives") not to, directly or indirectly, (i) initiate, solicit, knowingly encourage or knowingly facilitate inquiries or proposals with respect to, (ii) engage or participate in any negotiations with any person concerning or (iii) provide any confidential or nonpublic information or data to, or have or participate in any discussions with, any person relating to, any Acquisition Proposal; provided, that, prior to receipt of the Requisite Company Vote, in the event Company receives an unsolicited bona fide written Acquisition Proposal and the Board of Directors of Company concludes in good faith that such Acquisition Proposal constitutes or is more likely than not result in a Superior Proposal, it may, and may permit its Subsidiaries and its and its Subsidiaries' Representatives to, furnish or cause to be furnished nonpublic information or data and participate in such negotiations or discussions to the extent that its Board of Directors concludes in good faith (after receiving the advice of its outside counsel, and with respect to financial matters, its financial advisors) that failure to take such actions would result in a violation of its fiduciary duties under applicable law; provided, further, that, prior to or substantially concurrently with providing any nonpublic information permitted to be provided pursuant to the foregoing proviso, Company shall have provided notice to Parent of its intention to provide such information, and shall have provided such information to Parent if not previously provided to Parent, and shall have entered into a confidentiality agreement with such third party on terms no less favorable to it than the Confidentiality Agreement, which confidentiality agreement shall not provide such person with any exclusive right to negotiate with Company.

(b) As used in this Agreement, "Acquisition Proposal" shall mean, other than the transactions contemplated by this Agreement, any offer, proposal, inquiry or indication of interest, made by a person (or a group of persons acting in concert within the meaning of Rule 13d-5 of the Exchange Act) relating to (i) any acquisition or purchase, direct or indirect, of twenty percent (20%) or more of the consolidated assets of Company and its Subsidiaries or twenty percent (20%) or more of any class of voting securities of Company or its Subsidiaries whose assets, individually or in the aggregate, constitute more than twenty percent (20%) of the consolidated assets of Company, (ii) any tender offer or exchange offer that, if consummated, would result in such third party beneficially owning twenty percent (20%) or more of any class of equity or voting securities of Company or its Subsidiaries whose assets, individually or in the aggregate, constitute more than twenty percent (20%) of the consolidated assets of Company, or (iii) a merger, consolidation, share exchange, other business combination, reorganization, recapitalization, liquidation, dissolution or other similar transaction involving Company or its Subsidiaries whose assets, individually or in the aggregate, constitute more than twenty percent (20%) of the consolidated assets of Company, except, in each case, any sale of whole loans and securitizations in the ordinary course of business and any bona fide internal reorganization.

(c) As used in this Agreement, "Superior Proposal" means a bona fide written Acquisition Proposal that the Board of Directors of Company concludes in good faith to be more favorable from a financial point of view to its stockholders than the Merger and the other transactions contemplated hereby, (i) after receiving the advice of its financial advisors (who shall be a nationally recognized investment banking firm), (ii) after taking into account the likelihood of consummation of such transaction on the terms set forth therein and (iii) after taking into account all legal (with the advice of outside counsel), financial (including the financing terms of any such proposal), regulatory and other aspects of such proposal (including any expense reimbursement provisions and conditions to closing) and any other relevant factors permitted under applicable law; provided, that for purposes of the definition of "Superior Proposal," the references to "20%" in the definition of Acquisition Proposal shall be deemed to be references to "a majority."

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

Company shall have received an opinion of Wachtell, Lipton, Rosen & Katz, in form and substance reasonably satisfactory to Company, dated as of the Closing Date and based on facts, representations and assumptions described in such opinion, to the effect that (i) the Merger will qualify as a "reorganization" within the meaning of Section 368(a) of the Code and (ii) that the Merger will not result in gain recognition to the holders of Company Common Stock pursuant to Section 367(a) of the Code (assuming that, in the case of any such holder who would be treated as a "five-percent transferee shareholder" within the meaning of Treasury Regulations Section 1.367(a)-3(c)(5)(ii), such holder enters into a five-year gain recognition agreement in the form provided in Treasury Regulations Section 1.367(a)-8, as provided for in Treasury Regulations Section 1.367(a)-3(c)(1)(iii)(B), and complies with the requirements of that agreement and Treasury Regulations Section 1.367(a)-8 for avoiding the recognition of gain). In rendering such opinion, Wachtell, Lipton, Rosen & Katz will be entitled to receive and rely upon customary certificates and representations of officers of Parent, Holdco and Company.

TERMINATION AND AMENDMENT

8.1 Termination. This Agreement may be terminated at any time prior to the Effective Time, whether before or after adoption of this Agreement by the stockholders of Company:

(a) by mutual consent of Parent and Company in a written instrument;

(b) by either Parent or Company if any Governmental Entity that must grant a Requisite Regulatory Approval has denied approval of the Merger or the other transactions contemplated hereby and such denial has become final and non-appealable or any Governmental Entity of competent jurisdiction shall have issued a final non-appealable order, injunction or decree permanently enjoining or otherwise prohibiting or making illegal the consummation of the Merger or the other transactions contemplated hereby, unless the failure to obtain a Requisite Regulatory Approval shall be due to the failure of the party seeking to terminate this Agreement to perform or observe the covenants and agreements of such party set forth herein;

(c) by either Parent or Company if the Merger shall not have been consummated on or before the first anniversary of the date of this Agreement (the "Termination Date"), unless the failure of the Closing to occur by such date shall be due to the failure of the party seeking to terminate this Agreement to perform or observe the covenants and agreements of such party set forth herein;

(d) by either Parent or Company (provided, that the terminating party is not then in material breach of any representation, warranty, covenant or other agreement contained herein) if there shall have been a breach of any of the covenants or agreements or any of the representations or warranties (or any such representation or warranty shall cease to be true) set forth in this Agreement on the part of Company, in the case of a termination by Parent, or Parent, in the case of a termination by Company, which breach or failure to be true, either individually or in the aggregate with all other breaches by such party (or failures of such representations or warranties to be true), would constitute, if occurring or continuing on the Closing Date, the failure of a condition set forth in Section 7.2 or Section 7.3, as the case may be, and which is not cured before the earlier of the Termination Date and 60 days following written notice to Company, in the case of a termination by Parent, or Parent, in the case of a termination by Company, or by its nature or timing cannot be cured during such period; or

(e) by Parent, if (i) prior to such time as the Requisite Company Vote is obtained, Company or the Board of Directors of Company (A) submits this Agreement to its stockholders without a recommendation for approval, or otherwise withdraws or materially and adversely modifies (or publicly discloses its intention to withdraw or materially and adversely modify) its recommendation as contemplated by Section 6.3(a), or recommends to its stockholders an Acquisition Proposal other than the Merger, or (B) materially breaches its obligations under Section 6.3 or its obligations under Section 6.10; or (ii) a tender offer or exchange offer for 20% or more of the outstanding shares of Company Common Stock is commenced (other than by Parent or a Subsidiary thereof), and the Board of Directors of Company recommends that the stockholders of Company tender their shares in such tender or exchange offer or otherwise fails to recommend that such stockholders reject such tender offer or exchange offer within the 10 business day period specified in Rule 14e-2(a) under the Exchange Act.

The party desiring to terminate this Agreement pursuant to clause (b), (c), (d) or (e) of this Section 8.1 shall give written notice of such termination to the other party in accordance with Section 9.5, specifying the provision or provisions hereof pursuant to which such termination is effected.

8.2 Effect of Termination.

(a) In the event of termination of this Agreement by either Parent or Company as provided in Section 8.1, this Agreement shall forthwith become void and have no effect, and none of Parent, Company, Holdco, any of their respective Subsidiaries or any of the officers or directors of any of them shall have any liability of any nature whatsoever hereunder, or in connection with the transactions contemplated hereby, except that (i) Sections 3.3(a), 3.7, 4.3(a), 4.7, 6.2(b), this Section 8.2 and Article IX shall survive any termination of this Agreement, and (ii) notwithstanding anything to the contrary contained in this Agreement, neither Parent nor Company shall be relieved or released from any liabilities or damages arising out of its willful and material breach of any provision of this Agreement (which, in the case of Company, shall include the loss to the holders of Company Common Stock of the economic benefits of the Merger, including the loss of premium offered to such holders).

(b) (i) In the event that (A) after the date of this Agreement a bona fide Acquisition Proposal shall have been made known to senior management of Company or shall have been made directly to its stockholders generally or any person shall have publicly announced (and not withdrawn) an Acquisition Proposal with respect to Company and thereafter (x) this Agreement is terminated by either Parent or Company pursuant to Section 8.1(c) without the Requisite Company Vote having been obtained, or (y) this Agreement is terminated by Parent pursuant to Section 8.1(d), and (B) prior to the date that is fifteen (15) months after the date of any applicable termination described in clauses (x) through (y) hereof, Company enters into a definitive agreement or consummates a transaction with respect to an Acquisition Proposal (whether or not the same Acquisition Proposal as that referred to above), then Company shall, on the earlier of the date it enters into such definitive agreement and the date of consummation of such transaction, pay Parent, by wire transfer of same day funds, a fee equal to $150,000,000 (the "Termination Fee"); provided, that for purposes of this Section 8.2(b), all references in the definition of Acquisition Proposal to "20%" shall instead refer to "50%".

(ii) In the event that this Agreement is terminated by Parent pursuant to Section 8.1(e) (or this Agreement is terminated pursuant to Section 8.1(c) but at the time of such termination Parent could have terminated this Agreement pursuant to Section 8.1(e)), then Company shall pay Parent, by wire transfer of same day funds, the Termination Fee as promptly as reasonably practical after the date of termination (and, in any event, within three (3) business days thereafter).

(c) Notwithstanding anything to the contrary herein, but without limiting the right of any party to recover liabilities or damages, the maximum aggregate amount of fees payable by Company under this Section 8.2 shall be equal to the Termination Fee, and in no event shall Company be obligated to pay the Termination Fee on more than one occasion.

(d) Each of Parent and Company acknowledges that the agreements contained in this Section 8.2 are an integral part of the transactions contemplated by this Agreement, and that, without these agreements, the other party would not enter into this Agreement; accordingly, if Company fails promptly to pay the amount due pursuant to this Section 8.2, and, in order to obtain such payment, Parent commences a suit which results in a judgment against Company for the Termination Fee or any portion thereof, Company shall pay the costs and expenses of Parent (including reasonable attorneys' fees and expenses) in connection with such suit. In addition, if Company fails to pay the amounts payable pursuant to this Section 8.2, then Company shall pay interest on such overdue amounts (for the period commencing as of the date that such overdue amount was originally required to be paid and ending on the date that such overdue amount is actually paid in full) at a rate per annum equal to the "prime rate" (as announced by JPMorgan Chase & Co. or any successor thereto) in effect on the date on which such payment was required

A-51

to be made for the period commencing as of the date that such overdue amount was originally required to be paid. The amount payable by Company pursuant to Section 8.2(b) shall, except in the case of fraud or willful misconduct, be the sole monetary remedy of Parent in the event of a termination of this Agreement specified in such section.

ARTICLE IX

APPENDIX B—OPINION OF GOLDMAN SACHS

PERSONAL AND CONFIDENTIAL

June 29, 2016
Board of Directors
PrivateBancorp, Inc.
120 S. LaSalle Street
Chicago, IL 60603
Ladies and Gentlemen:

You have requested our opinion as to the fairness from a financial point of view to the holders (other than Canadian Imperial Bank of Commerce ("CIBC") and its affiliates) of the outstanding shares of common stock, without par value (the "Shares"), of PrivateBancorp, Inc. (the "Company") of the Aggregate Consideration (as defined below) to be paid to such holders pursuant to the Agreement and Plan of Merger, dated as of June 29, 2016 (the "Agreement"), by and among CIBC, CIBC Holdco Inc., a direct, wholly owned subsidiary of CIBC ("Holdco"), and the Company. Pursuant to the Agreement, the Company will be merged with and into Holdco and each outstanding Share will be converted into $18.80 in cash (the "Cash Consideration") and 0.3657 common shares ("CIBC Common Shares") of CIBC (the "Share Consideration," together with the Cash Consideration, the "Aggregate Consideration").

Goldman, Sachs & Co. and its affiliates are engaged in advisory, underwriting and financing, principal investing, sales and trading, research, investment management and other financial and non-financial activities and services for various persons and entities. Goldman, Sachs & Co. and its affiliates and employees, and funds or other entities they manage or in which they invest or have other economic interests or with which they co-invest, may at any time purchase, sell, hold or vote long or short positions and investments in securities, derivatives, loans, commodities, currencies, credit default swaps and other financial instruments of the Company, CIBC, any of their respective affiliates and third parties, or any currency or commodity that may be involved in the transaction contemplated by the Agreement (the "Transaction"). We have acted as financial advisor to the Company in connection with, and have participated in certain of the negotiations leading to, the Transaction. We expect to receive fees for our services in connection with the Transaction, the principal portion of which is contingent upon consummation of the Transaction, and the Company has agreed to reimburse certain of our expenses arising, and indemnify us against certain liabilities that may arise, out of our engagement. We have provided certain financial advisory and/or underwriting services to the Company and/or its affiliates from time to time. We have provided certain financial advisory and/or underwriting services to CIBC and/or its affiliates from time to time for which our Investment Banking Division has received, and may receive, compensation. We may also in the future provide financial advisory and/or underwriting services to the Company, CIBC and their respective affiliates for which our Investment Banking Division may receive compensation.

In connection with this opinion, we have reviewed, among other things, the Agreement; annual reports to stockholders and Annual Reports on Form 10-K of the Company for the five fiscal years ended December 31, 2015 and annual reports to shareholders and Annual Reports on Form 40-F of CIBC for the five fiscal years ended October 31, 2015; certain interim reports to stockholders and Quarterly Reports on Form 10-Q of the Company and certain interim reports to shareholders of CIBC; certain other communications from the Company to its stockholders and from CIBC to its shareholders; certain publicly available research analyst reports for the Company and CIBC; and certain internal financial analyses and forecasts for the Company on a stand-alone basis prepared by its management ("Company Financial Forecasts"), certain financial analyses and forecasts for CIBC on a stand-alone basis reflecting Wall Street analyst consensus estimates for CIBC for 2016 and 2017, as

B-1

Table of Contents

extrapolated by management of the Company for periods thereafter ("CIBC Forecasts"), certain financial analyses and forecasts for the Company as owned by CIBC provided by the Company and comprised of the Company Financial Forecasts and estimates and judgments of the management of the Company with respect to ownership of the Company by CIBC ("Company As-Owned Forecasts") and certain financial analyses and forecasts for the combined Company and CIBC provided by the Company and comprised of the CIBC Forecasts and the Company As-Owned Forecasts, in each case, as approved for our use by the Company (the "Forecasts"), including certain operating synergies and other adjustments anticipated by the management of the Company to result from the Transaction, as approved for our use by the Company (the "Synergies"). We have also held discussions with members of the senior management of the Company regarding their assessment of the past and current business operations, financial condition and future prospects of the Company and CIBC and the strategic rationale for, and the potential benefits of, the Transaction and with members of the senior management of CIBC regarding their assessment of the past and current business operations, financial condition and future prospects of the CIBC and the strategic rationale for, and the potential benefits of, the Transaction; reviewed the reported price and trading activity for the Shares and CIBC Common Shares; compared certain financial and stock market information for the Company and CIBC with similar information for certain other companies the securities of which are publicly traded; reviewed the financial terms of certain recent business combinations in the banking industry; and performed such other studies and analyses, and considered such other factors, as we deemed appropriate.

For purposes of rendering this opinion, we have, with your consent, relied upon and assumed the accuracy and completeness of all of the financial, legal, regulatory, tax, accounting and other information provided to, discussed with or reviewed by, us, without assuming any responsibility for independent verification thereof. In that regard, we have assumed with your consent that the Forecasts, including the Synergies, have been reasonably prepared and reflect the best currently available estimates and judgments of the management of the Company. We have not reviewed individual credit files nor have we made an independent evaluation or appraisal of the assets and liabilities (including any contingent, derivative or other off-balance-sheet assets and liabilities) of the Company or CIBC or any of their respective subsidiaries and we have not been furnished with any such evaluation or appraisal. We are not experts in the evaluation of loan and lease portfolios for purposes of assessing the adequacy of the allowances and marks for losses with respect thereto and, accordingly, we have assumed that such allowances and marks are in the aggregate adequate to cover such losses. We have assumed that all governmental, regulatory or other consents and approvals necessary for the consummation of the Transaction will be obtained without any adverse effect on the Company or CIBC or on the expected benefits of the Transaction in any way meaningful to our analysis. We have assumed that the Transaction will be consummated on the terms set forth in the Agreement, without the waiver or modification of any term or condition the effect of which would be in any way meaningful to our analysis.

Our opinion does not address the underlying business decision of the Company to engage in the Transaction, or the relative merits of the Transaction as compared to any strategic alternatives that may be available to the Company; nor does it address any legal, regulatory, tax or accounting matters. We were not requested to solicit, and did not solicit, interest from other parties with respect to an acquisition of, or other business combination with, the Company or any other alternative transaction. This opinion addresses only the fairness from a financial point of view to the holders (other than CIBC and its affiliates) of Shares, as of the date hereof, of the Aggregate Consideration to be paid to such holders pursuant to the Agreement. We do not express any view on, and our opinion does not address, any other term or aspect of the Agreement or Transaction or any term or aspect of any other agreement or instrument contemplated by the Agreement or entered into or amended in connection with the Transaction, including, the fairness of the Transaction to, or any consideration received in connection therewith by, the holders of any other class of securities, creditors, or other constituencies of the Company; nor as to the fairness of the amount or nature of any compensation to be paid or

B-2

Table of Contents

payable to any of the officers, directors or employees of the Company, or class of such persons, in connection with the Transaction, whether relative to the Aggregate Consideration to be paid to the holders (other than CIBC and its affiliates) of Shares pursuant to the Agreement or otherwise. We are not expressing any opinion as to the prices at which the CIBC Common Shares will trade at any time or as to the impact of the Transaction on the solvency or viability of the Company or CIBC or the ability of the Company or CIBC to pay their respective obligations when they come due. Our opinion is necessarily based on economic, monetary, market and other conditions as in effect on, and the information made available to us as of, the date hereof and we assume no responsibility for updating, revising or reaffirming this opinion based on circumstances, developments or events occurring after the date hereof. Our advisory services and the opinion expressed herein are provided for the information and assistance of the Board of Directors of the Company in connection with its consideration of the Transaction and such opinion does not constitute a recommendation as to how any holder of Shares should vote with respect to such Transaction or any other matter. This opinion has been approved by a fairness committee of Goldman, Sachs & Co.

Based upon and subject to the foregoing, it is our opinion that, as of the date hereof, the Aggregate Consideration to be paid to the holders (other than CIBC and its affiliates) of Shares pursuant to the Agreement is fair from a financial point of view to such holders.

Very truly yours,

/s/ Goldman, Sachs & Co.

Ladies and Gentlemen:

PrivateBancorp, Inc. ("Company"), Canadian Imperial Bank of Commerce ("Parent") and CIBC Holdco Inc. ("Holdco"), a direct, wholly-owned subsidiary of Parent, are proposing to enter into an Agreement and Plan of Merger (the "Agreement") pursuant to which Company will merge with and into Holdco (the "Merger") with Holdco surviving the Merger. Pursuant to the terms of the Agreement, upon the Effective Time of the Merger, each share of common stock, no par value, of Company issued and outstanding immediately prior to the Effective Time ("Company Common Stock"), except for certain shares of Company Common Stock as specified in the Agreement, shall be converted, in accordance with the procedures set forth in the Agreement, into the right to receive, without interest, (i) 0.3657 common shares of Parent (the "Per Share Stock Consideration"), and (ii) $18.80 in cash (the "Per Share Cash Consideration"). The terms and conditions of the Merger are more fully set forth in the Agreement. The Per Share Stock Consideration and the Per Share Cash Consideration are collectively referred to herein as the "Merger Consideration." Capitalized terms used herein without definition shall have the meanings assigned to them in the Agreement. You have requested our opinion as to the fairness, from a financial point of view, of the Merger Consideration to the holders of Company Common Stock.

Sandler O'Neill & Partners, L.P. ("Sandler O'Neill", "we" or "our"), as part of its investment banking business, is regularly engaged in the valuation of financial institutions and their securities in connection with mergers and acquisitions and other corporate transactions. In connection with this opinion, we have reviewed and considered, among other things: (i) the Agreement; (ii) certain publicly available financial statements and other historical financial information of Company that we deemed relevant; (iii) certain publicly available financial statements and other historical financial information of Parent that we deemed relevant; (iv) internal financial projections for Company for the years ending December 31, 2016 through December 31, 2022, as provided by the senior management of Company; (v) financial projections for Parent for the years ending October 31, 2016 through October 31, 2022, as provided by the senior management of Company; (vi) the pro forma financial impact of the Merger on Parent based on certain assumptions relating to transaction expenses, purchase accounting adjustments, a core deposit intangible asset and cost savings, as well as internal financial projections for Company, as owned by Parent, for the years ending December 31, 2016 through December 31, 2022, as provided by the senior management of Company; (vii) the publicly reported historical price and trading activity for Company Common Stock and Parent common shares, including a comparison of certain stock market information for Company and Parent common stock and certain stock indices as well as publicly available information for certain other similar companies, the securities of which are publicly traded; (viii) a comparison of certain financial information for Company and Parent with similar institutions for which information is publicly available; (ix) the financial terms of certain recent business combinations in the banking industry (on a regional and 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 senior management of Company the business, financial condition, results of operations and prospects of Company and held similar discussions with certain members of senior management of Parent 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 and reviewed by us from public sources, that was provided to us by Company or 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 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. We have not been asked to and have not undertaken an independent verification of any of 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 or any of their respective subsidiaries, nor have we been furnished with any such evaluations or appraisals. We render no opinion or evaluation on the collectability of any assets or the future performance of any loans of Company or Parent or any of their respective subsidiaries. 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 or any of their respective subsidiaries. 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, Sandler O'Neill used internal financial projections for Company for the years ending December 31, 2016 through December 31, 2022, as provided by the senior management of Company. In addition, in preparing its analyses Sandler O'Neill used financial projections for Parent for the years ending October 31, 2016 through October 31, 2022, as provided by the senior management of Company. Sandler O'Neill also received and used in its pro forma analyses certain assumptions relating to transaction expenses, purchase accounting adjustments, a core deposit intangible asset and cost savings, as well as internal financial projections for Company, as owned by Parent, for the years ending December 31, 2016 through December31, 2022, as provided by the senior management of Company. With respect to the foregoing information, the management of Company confirmed to us that such information reflected the best currently available projections, estimates and judgment of senior management of the future financial performance of Company and Parent, as applicable, and we assumed that such performance would be achieved. We express no opinion as to such projections, estimates or judgments, 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 analysis that Company and Parent will remain as going concerns for all periods relevant to our analyses.

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, that all of the representations and warranties contained in such agreements are true and correct in all material respects, that 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 or the benefits contemplated by the Merger or any related transaction, and (iii) the Merger and any related transaction 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. We express no opinion as to any of the legal, accounting or tax matters relating to the Merger or any other transactions contemplated in connection therewith.

Our analyses and opinion are necessarily based on financial, 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 values of Company Common Stock or Parent common shares 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 will receive a fee for rendering this opinion. 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. We have not provided any other investment banking services to Company in the two years immediately preceding the date hereof, nor have we provided any investment banking services to Parent in the two years immediately 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 or Parent and their respective affiliates. We may also actively trade the equity and debt securities of Company and Parent or their respective affiliates for our own account and for the accounts of our customers.

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 adoption of the Agreement and approval of the Merger. Our opinion is directed only 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 the 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 amount of compensation to be received in the Merger by any Company or Parent 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 Sandler O'Neill's fairness opinion committee. This opinion shall not be reproduced without Sandler O'Neill's prior written consent; provided, however, Sandler O'Neill will provide its consent for the opinion to be included in regulatory filings to be completed 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 holders of Company Common Stock from a financial point of view.

APPENDIX D—SECTION 262 OF THE GENERAL CORPORATION LAW OF THE STATE OF DELAWARE

§ 262. Appraisal rights.

(a)

Any stockholder of a corporation of this State who holds shares of stock on the date of the making of a demand pursuant to subsection (d) of this section with respect to such shares, who continuously holds such shares through the effective date of the merger or consolidation, who has otherwise complied with subsection (d) of this section and who has neither voted in favor of the merger or consolidation nor consented thereto in writing pursuant to § 228 of this title shall be entitled to an appraisal by the Court of Chancery of the fair value of the stockholder's shares of stock under the circumstances described in subsections (b) and (c) of this section. As used in this section, the word "stockholder" means a holder of record of stock in a corporation; the words "stock" and "share" mean and include what is ordinarily meant by those words; and the words "depository receipt" mean a receipt or other instrument issued by a depository representing an interest in 1 or more shares, or fractions thereof, solely of stock of a corporation, which stock is deposited with the depository.

(b)

Appraisal rights shall be available for the shares of any class or series of stock of a constituent corporation in a merger or consolidation to be effected pursuant to § 251 (other than a merger effected pursuant to § 251(g) of this title and, subject to paragraph (b)(3) of this section, § 251(h) of this title), § 252, § 254, § 255, § 256, § 257, § 258, § 263 or § 264 of this title:

(1)

Provided, however, that, except as expressly provided in § 363(b) of this title, no appraisal rights under this section shall be available for the shares of any class or series of stock, which stock, or depository receipts in respect thereof, at the record date fixed to determine the stockholders entitled to receive notice of the meeting of stockholders to act upon the agreement of merger or consolidation, were either: (i) listed on a national securities exchange or (ii) held of record by more than 2,000 holders; and further provided that no appraisal rights shall be available for any shares of stock of the constituent corporation surviving a merger if the merger did not require for its approval the vote of the stockholders of the surviving corporation as provided in § 251(f) of this title.

(2)

Notwithstanding paragraph (b)(1) of this section, appraisal rights under this section shall be available for the shares of any class or series of stock of a constituent corporation if the holders thereof are required by the terms of an agreement of merger or consolidation pursuant to §§ 251, 252, 254, 255, 256, 257, 258, 263 and 264 of this title to accept for such stock anything except:

a.: Shares of stock of the corporation surviving or resulting from such merger or consolidation, or depository receipts in respect thereof;
b.: Shares of stock of any other corporation, or depository receipts in respect thereof, which shares of stock (or depository receipts in respect thereof) or depository receipts at the effective date of the merger or consolidation will be either listed on a national securities exchange or held of record by more than 2,000 holders;
c.: Cash in lieu of fractional shares or fractional depository receipts described in the foregoing paragraphs (b)(2)a. and b. of this section; or
d.: Any combination of the shares of stock, depository receipts and cash in lieu of fractional shares or fractional depository receipts described in the foregoing paragraphs (b)(2)a., b. and c. of this section.

(3)

In the event all of the stock of a subsidiary Delaware corporation party to a merger effected under § 251(h), § 253 or § 267 of this title is not owned by the parent immediately prior to

D-1

Table of Contents

the merger, appraisal rights shall be available for the shares of the subsidiary Delaware corporation.

(4): In the event of an amendment to a corporation's certificate of incorporation contemplated by § 363(a) of this title, appraisal rights shall be available as contemplated by § 363(b) of this title, and the procedures of this section, including those set forth in subsections (d) and (e) of this section, shall apply as nearly as practicable, with the word "amendment" substituted for the words "merger or consolidation," and the word "corporation" substituted for the words "constituent corporation" and/or "surviving or resulting corporation."

(c)

Any corporation may provide in its certificate of incorporation that appraisal rights under this section shall be available for the shares of any class or series of its stock as a result of an amendment to its certificate of incorporation, any merger or consolidation in which the corporation is a constituent corporation or the sale of all or substantially all of the assets of the corporation. If the certificate of incorporation contains such a provision, the provisions of this section, including those set forth in subsections (d) and (e) of this section, shall apply as nearly as is practicable.

(d)

Appraisal rights shall be perfected as follows:

(1): If a proposed merger or consolidation for which appraisal rights are provided under this section is to be submitted for approval at a meeting of stockholders, the corporation, not less than 20 days prior to the meeting, shall notify each of its stockholders who was such on the record date for notice of such meeting (or such members who received notice in accordance with § 255(c) of this title) with respect to shares for which appraisal rights are available pursuant to subsection (b) or (c) of this section that appraisal rights are available for any or all of the shares of the constituent corporations, and shall include in such notice a copy of this section and, if 1 of the constituent corporations is a nonstock corporation, a copy of § 114 of this title. Each stockholder electing to demand the appraisal of such stockholder's shares shall deliver to the corporation, before the taking of the vote on the merger or consolidation, a written demand for appraisal of such stockholder's shares. Such demand will be sufficient if it reasonably informs the corporation of the identity of the stockholder and that the stockholder intends thereby to demand the appraisal of such stockholder's shares. A proxy or vote against the merger or consolidation shall not constitute such a demand. A stockholder electing to take such action must do so by a separate written demand as herein provided. Within 10 days after the effective date of such merger or consolidation, the surviving or resulting corporation shall notify each stockholder of each constituent corporation who has complied with this subsection and has not voted in favor of or consented to the merger or consolidation of the date that the merger or consolidation has become effective; or
(2): If the merger or consolidation was approved pursuant to § 228, § 251(h), § 253, or § 267 of this title, then either a constituent corporation before the effective date of the merger or consolidation or the surviving or resulting corporation within 10 days thereafter shall notify each of the holders of any class or series of stock of such constituent corporation who are entitled to appraisal rights of the approval of the merger or consolidation and that appraisal rights are available for any or all shares of such class or series of stock of such constituent corporation, and shall include in such notice a copy of this section and, if 1 of the constituent corporations is a nonstock corporation, a copy of § 114 of this title. Such notice may, and, if given on or after the effective date of the merger or consolidation, shall, also notify such stockholders of the effective date of the merger or consolidation. Any stockholder entitled to appraisal rights may, within 20 days after the date of mailing of such notice or, in the case of a merger approved pursuant to § 251(h) of this title, within the later of the consummation of the tender or exchange offer contemplated by § 251(h) of this title and 20 days after the date

D-2

Table of Contents

of mailing of such notice, demand in writing from the surviving or resulting corporation the appraisal of such holder's shares. Such demand will be sufficient if it reasonably informs the corporation of the identity of the stockholder and that the stockholder intends thereby to demand the appraisal of such holder's shares. If such notice did not notify stockholders of the effective date of the merger or consolidation, either (i) each such constituent corporation shall send a second notice before the effective date of the merger or consolidation notifying each of the holders of any class or series of stock of such constituent corporation that are entitled to appraisal rights of the effective date of the merger or consolidation or (ii) the surviving or resulting corporation shall send such a second notice to all such holders on or within 10 days after such effective date; provided, however, that if such second notice is sent more than 20 days following the sending of the first notice or, in the case of a merger approved pursuant to § 251(h) of this title, later than the later of the consummation of the tender or exchange offer contemplated by § 251(h) of this title and 20 days following the sending of the first notice, such second notice need only be sent to each stockholder who is entitled to appraisal rights and who has demanded appraisal of such holder's shares in accordance with this subsection. An affidavit of the secretary or assistant secretary or of the transfer agent of the corporation that is required to give either notice that such notice has been given shall, in the absence of fraud, be prima facie evidence of the facts stated therein. For purposes of determining the stockholders entitled to receive either notice, each constituent corporation may fix, in advance, a record date that shall be not more than 10 days prior to the date the notice is given, provided, that if the notice is given on or after the effective date of the merger or consolidation, the record date shall be such effective date. If no record date is fixed and the notice is given prior to the effective date, the record date shall be the close of business on the day next preceding the day on which the notice is given.

(e): Within 120 days after the effective date of the merger or consolidation, the surviving or resulting corporation or any stockholder who has complied with subsections (a) and (d) of this section hereof and who is otherwise entitled to appraisal rights, may commence an appraisal proceeding by filing a petition in the Court of Chancery demanding a determination of the value of the stock of all such stockholders. Notwithstanding the foregoing, at any time within 60 days after the effective date of the merger or consolidation, any stockholder who has not commenced an appraisal proceeding or joined that proceeding as a named party shall have the right to withdraw such stockholder's demand for appraisal and to accept the terms offered upon the merger or consolidation. Within 120 days after the effective date of the merger or consolidation, any stockholder who has complied with the requirements of subsections (a) and (d) of this section hereof, upon written request, shall be entitled to receive from the corporation surviving the merger or resulting from the consolidation a statement setting forth the aggregate number of shares not voted in favor of the merger or consolidation and with respect to which demands for appraisal have been received and the aggregate number of holders of such shares. Such written statement shall be mailed to the stockholder within 10 days after such stockholder's written request for such a statement is received by the surviving or resulting corporation or within 10 days after expiration of the period for delivery of demands for appraisal under subsection (d) of this section hereof, whichever is later. Notwithstanding subsection (a) of this section, a person who is the beneficial owner of shares of such stock held either in a voting trust or by a nominee on behalf of such person may, in such person's own name, file a petition or request from the corporation the statement described in this subsection.
(f): Upon the filing of any such petition by a stockholder, service of a copy thereof shall be made upon the surviving or resulting corporation, which shall within 20 days after such service file in the office of the Register in Chancery in which the petition was filed a duly verified list containing the names and addresses of all stockholders who have demanded payment for their shares and with whom agreements as to the value of their shares have not been reached by the surviving or resulting

D-3

Table of Contents

corporation. If the petition shall be filed by the surviving or resulting corporation, the petition shall be accompanied by such a duly verified list. The Register in Chancery, if so ordered by the Court, shall give notice of the time and place fixed for the hearing of such petition by registered or certified mail to the surviving or resulting corporation and to the stockholders shown on the list at the addresses therein stated. Such notice shall also be given by 1 or more publications at least 1 week before the day of the hearing, in a newspaper of general circulation published in the City of Wilmington, Delaware or such publication as the Court deems advisable. The forms of the notices by mail and by publication shall be approved by the Court, and the costs thereof shall be borne by the surviving or resulting corporation.

(g): At the hearing on such petition, the Court shall determine the stockholders who have complied with this section and who have become entitled to appraisal rights. The Court may require the stockholders who have demanded an appraisal for their shares and who hold stock represented by certificates to submit their certificates of stock to the Register in Chancery for notation thereon of the pendency of the appraisal proceedings; and if any stockholder fails to comply with such direction, the Court may dismiss the proceedings as to such stockholder.
(h): After the Court determines the stockholders entitled to an appraisal, the appraisal proceeding shall be conducted in accordance with the rules of the Court of Chancery, including any rules specifically governing appraisal proceedings. Through such proceeding the Court shall determine the fair value of the shares exclusive of any element of value arising from the accomplishment or expectation of the merger or consolidation, together with interest, if any, to be paid upon the amount determined to be the fair value. In determining such fair value, the Court shall take into account all relevant factors. Unless the Court in its discretion determines otherwise for good cause shown, interest from the effective date of the merger through the date of payment of the judgment shall be compounded quarterly and shall accrue at 5% over the Federal Reserve discount rate (including any surcharge) as established from time to time during the period between the effective date of the merger and the date of payment of the judgment. Upon application by the surviving or resulting corporation or by any stockholder entitled to participate in the appraisal proceeding, the Court may, in its discretion, proceed to trial upon the appraisal prior to the final determination of the stockholders entitled to an appraisal. Any stockholder whose name appears on the list filed by the surviving or resulting corporation pursuant to subsection (f) of this section and who has submitted such stockholder's certificates of stock to the Register in Chancery, if such is required, may participate fully in all proceedings until it is finally determined that such stockholder is not entitled to appraisal rights under this section.
(i): The Court shall direct the payment of the fair value of the shares, together with interest, if any, by the surviving or resulting corporation to the stockholders entitled thereto. Payment shall be so made to each such stockholder, in the case of holders of uncertificated stock forthwith, and the case of holders of shares represented by certificates upon the surrender to the corporation of the certificates representing such stock. The Court's decree may be enforced as other decrees in the Court of Chancery may be enforced, whether such surviving or resulting corporation be a corporation of this State or of any state.
(j): The costs of the proceeding may be determined by the Court and taxed upon the parties as the Court deems equitable in the circumstances. Upon application of a stockholder, the Court may order all or a portion of the expenses incurred by any stockholder in connection with the appraisal proceeding, including, without limitation, reasonable attorney's fees and the fees and expenses of experts, to be charged pro rata against the value of all the shares entitled to an appraisal.
(k): From and after the effective date of the merger or consolidation, no stockholder who has demanded appraisal rights as provided in subsection (d) of this section shall be entitled to vote such stock for any purpose or to receive payment of dividends or other distributions on the stock

Table of Contents

(except dividends or other distributions payable to stockholders of record at a date which is prior to the effective date of the merger or consolidation); provided, however, that if no petition for an appraisal shall be filed within the time provided in subsection (e) of this section, or if such stockholder shall deliver to the surviving or resulting corporation a written withdrawal of such stockholder's demand for an appraisal and an acceptance of the merger or consolidation, either within 60 days after the effective date of the merger or consolidation as provided in subsection (e) of this section or thereafter with the written approval of the corporation, then the right of such stockholder to an appraisal shall cease. Notwithstanding the foregoing, no appraisal proceeding in the Court of Chancery shall be dismissed as to any stockholder without the approval of the Court, and such approval may be conditioned upon such terms as the Court deems just; provided, however that this provision shall not affect the right of any stockholder who has not commenced an appraisal proceeding or joined that proceeding as a named party to withdraw such stockholder's demand for appraisal and to accept the terms offered upon the merger or consolidation within 60 days after the effective date of the merger or consolidation, as set forth in subsection (e) of this section.

(l): The shares of the surviving or resulting corporation to which the shares of such objecting stockholders would have been converted had they assented to the merger or consolidation shall have the status of authorized and unissued shares of the surviving or resulting corporation.
