To vote on a non-binding, advisory proposal approving executive compensation;



4.

To vote on a shareholder proposal requesting that the Board of Directors take steps to eliminate classification with respect to director elections. This proposal is opposed by our Board of Directors; and

To transact any other business that is properly submitted before the Annual Meeting or any adjournments or postponements of the Annual Meeting.

The record date for the Annual Meeting is March 20, 2009 (the "Record Date"). Only shareholders of record at the close of business on the Record Date can vote at the Annual Meeting. Comerica mailed this Notice of Annual Meeting to those shareholders. Action may be taken at the Annual Meeting on any of the foregoing proposals on the date specified above or any date or dates to which the Annual Meeting may be adjourned or postponed.

Comerica will have a list of shareholders who can vote at the Annual Meeting available for inspection by shareholders at the Annual Meeting and, for 10 days prior to the Annual Meeting, during regular business hours at the offices of the Comerica Corporate Legal Department, Comerica Bank Tower, 1717 Main Street, Dallas, Texas 75201.

If you plan to attend the Annual Meeting but are not a shareholder of record because you hold your shares in street name, please bring evidence of your beneficial ownership of your shares with you to the Annual Meeting. See the "Questions and Answers" section of the proxy statement for a discussion of the difference between a shareholder of record and a street name holder.

2009 PROXY STATEMENT

QUESTIONS AND ANSWERS

---

What is a proxy?

A proxy is your authorization for someone else to vote for you in the way that you want to vote. When you complete and submit a proxy card or use the automated telephone voting system or the Internet voting system, you are submitting a proxy. The Board of Directors of Comerica Incorporated ("Comerica" or the "Company") is soliciting this proxy. All references in this proxy statement to "you" will mean you, the shareholder, and to "yours" will mean the shareholder's or shareholders', as appropriate.

---

What is a proxy statement?

A proxy statement is a document the United States Securities and Exchange Commission (the "SEC") requires to explain the matters on which you are asked to vote on by proxy and to disclose certain related information. This proxy statement and, if applicable, the accompanying proxy card were first mailed to the shareholders on or about April [    ], 2009.

---

Who can vote?

Only record holders of Comerica's common stock at the close of business on March 20, 2009, the Record Date, can vote at the Annual Meeting. Each shareholder of record has one vote, for each share of common stock owned, on each matter presented for a vote at the Annual Meeting.

---

What is the difference between a shareholder of record and a "street name" holder?

If your shares are registered directly in your name, you are considered the shareholder of record with respect to those shares.

If your shares are held in a stock brokerage account or by a bank or other nominee, then the brokerage firm, bank or other nominee is considered to be the shareholder of record with respect to those shares. However, you still are considered the beneficial owner of those shares, and your shares are said to be held in "street name." Street name holders generally cannot vote their shares directly and must instead instruct the brokerage firm, bank or other nominee how to vote their shares. See "How can I vote?" below.

---

How can I vote?

If you are a shareholder of record as of the Record Date, as opposed to a street name holder, you will be able to vote in four ways: In person, by telephone, by the Internet, or (in most cases) by proxy card. If you previously enrolled in a program to receive electronic versions of Comerica's annual

1

---

Table of Contents

report and proxy statement instead of receiving the printed versions, however, you may receive an email notice rather than a proxy card.

To vote by proxy card, sign, date and return the enclosed proxy card, if applicable. To vote by using the automated telephone voting system or the Internet voting system, the instructions for shareholders of record are as follows:

        TO VOTE BY TELEPHONE: 1-800-560-1965

•

Use any touch-tone telephone to vote your proxy.



•

Have your proxy card and the last four digits of your Social Security Number or Tax Identification Number available when you call.



•

Follow the simple instructions the system provides you.



•

You may dial this toll free number at your convenience, 24 hours a day, 7 days a week. The deadline for telephone voting is 11:59 p.m. (Central Time), May 18, 2009. For shares held in Comerica's employee benefit plans, the deadline is 11:59 p.m. (Central Time), May 17, 2009.

(OR)

        TO VOTE BY THE INTERNET:            http://www.ematerials.com/cma

•

Use the Internet to vote your proxy.



•

Have your proxy card and the last four digits of your Social Security Number or Tax Identification Number available when you access the website.



•

Follow the simple instructions to obtain your records and create an electronic ballot.



•

You may log on to this Internet site at your convenience, 24 hours a day, 7 days a week. The deadline for Internet voting is 11:59 p.m. (Central Time), May 18, 2009. For shares held in Comerica's employee benefit plans, the deadline is 11:59 p.m. (Central Time), May 17, 2009.

If you submit a proxy to Comerica before the Annual Meeting, the persons named as proxies will vote your shares as you directed. If no instructions are specified, the proxy will be voted for all of the listed director nominees, for the ratification of the appointment of the independent auditors, for the approval of executive compensation, and against the shareholder proposal requesting that the Board of Directors take steps to eliminate classification with respect to director elections.

You may revoke a proxy at any time before the proxy is exercised by:

(1)

delivering written notice of revocation to the Corporate Secretary of Comerica at the Corporate Legal Department, Comerica Bank Tower, 1717 Main Street, MC 6404, Dallas, Texas 75201;



(2)

submitting another properly completed proxy card that is later dated;



(3)

voting by telephone at a subsequent time;



(4)

voting by the Internet at a subsequent time; or



(5)

voting in person at the Annual Meeting.

If you hold your shares in "street name," you must vote your shares in the manner prescribed by your brokerage firm, bank or other nominee. Your brokerage firm, bank or other nominee has enclosed or otherwise provided a voting instruction card for you to use in directing the brokerage firm, bank or other nominee how to vote your shares. If you hold your shares in street name and you want to vote in person at the Annual Meeting, you must obtain a legal proxy from your broker and present it at the Annual Meeting.

What is a quorum?

There were 151,163,373 shares of Comerica's common stock issued and outstanding on the Record Date. A majority of the issued and outstanding shares, or 75,581,687 shares, present or represented by proxy, constitutes a quorum. A quorum must exist to conduct business at the Annual Meeting.

---

What vote is required?

Directors:    If a quorum exists, the nominees for Class I Director receiving a majority of the votes cast (i.e., the number of shares voted "for" a director nominee exceeds the number of votes cast "against" that nominee) will be elected as Class I Directors. Votes cast will include only votes cast with respect to stock present in person or represented by proxy at the meeting and entitled to vote and will exclude abstentions. Therefore, shares not present at the meeting, broker non-votes (described below) and shares voting "abstain" have no effect on the election of directors.

Other Proposals:    If a quorum exists, the proposals: (i) to ratify the appointment of independent auditors; (ii) to vote on an advisory, nonbinding proposal to approve executive compensation; and (iii) to vote on a shareholder proposal requesting that the Board of Directors take steps to eliminate classification with respect to director elections must receive the affirmative vote of a majority of the shares present in person or represented by proxy at the Annual Meeting and entitled to vote on the proposal in question. Therefore, abstentions will have the same effect as voting against the applicable proposal. Broker non-votes (described below) will not be counted as eligible to vote on the applicable proposal and, therefore, will have no effect on the outcome of the voting on that proposal.

If you hold your shares in street name and do not provide voting instructions to your broker, your shares will not be voted on any proposal on which your broker does not have discretionary authority to vote under the rules of the stock exchange or other organization of which it is a member. In this situation, a "broker non-vote" occurs.

Comerica will vote properly completed proxies it receives prior to the Annual Meeting in the way you direct. If you do not specify instructions, the shares represented by those properly completed proxies will be voted (i) to elect the nominees for Class I Directors; (ii) to ratify the appointment of Ernst & Young LLP as independent auditors; (iii) for the approval of executive compensation; and (iv) against the shareholder proposal requesting that the Board of Directors take steps to eliminate classification with respect to director elections. No other matters are currently scheduled to be presented at the Annual Meeting.

An independent third party, Wells Fargo Bank, N.A., will act as the inspector of the Annual Meeting and the tabulator of votes.

---

Who pays for the costs of the Annual Meeting?

Comerica pays the cost of preparing and printing the proxy statement and soliciting proxies. Comerica will solicit proxies primarily by mail, but may also solicit proxies personally and by telephone, the Internet, facsimile or other means. Comerica will use the services of Georgeson Inc., a proxy solicitation firm, at a cost of $9,000 plus out-of-pocket expenses and fees for any special services. Officers and regular employees of Comerica and its subsidiaries may also solicit proxies, but they will not receive additional compensation for soliciting proxies. Comerica also will reimburse banks, brokerage houses and other custodians, nominees and fiduciaries for their out-of-pocket expenses for forwarding solicitation materials to beneficial owners of Comerica's common stock.

---

How does the Board select nominees for the Board?

In identifying potential candidates for nomination as directors, the Governance, Compensation and Nominating Committee considers the specific qualities and skills of potential directors. Criteria for

3

---

Table of Contents

assessing nominees include a potential nominee's ability to represent the interests of Comerica's four core constituencies: its shareholders, its customers, the communities it serves and its employees. Minimum qualifications for a director nominee are experience in those areas that the Board determines are necessary and appropriate to meet the needs of Comerica, including leadership positions in public companies, small or middle market businesses, or not-for-profit, professional or educational organizations.

For those proposed director nominees who meet the minimum qualifications, the Governance, Compensation and Nominating Committee then assesses the proposed nominee's specific qualifications, evaluates his or her independence, and considers other factors, including skills, geographic location, considerations of diversity, standards of integrity, memberships on other boards (with a special focus on director interlocks), and ability and willingness to commit to serving on the Board for an extended period of time and to dedicate adequate time and attention to the affairs of Comerica as necessary to properly discharge his or her duties.

The Governance, Compensation and Nominating Committee will consider director nominees proposed by shareholders, as well as other shareholder proposals, provided such proposals comply with Comerica's applicable procedures as described below. More information regarding the selection of director nominees is included below under "Proposal I Submitted for Your Vote — Election of Directors."

---

When are shareholder proposals for the 2010 Annual Meeting due?

To be considered for inclusion in next year's proxy statement, all shareholder proposals must comply with applicable laws and regulations, including SEC Rule 14a-8, as well as Comerica's bylaws, and must be submitted in writing to the Corporate Secretary, Comerica Incorporated, Comerica Bank Tower, 1717 Main Street, MC 6404, Dallas, Texas 75201, and received by December [       ], 2009.

Under Comerica's bylaws, shareholders of Comerica must provide advance notice to Comerica if they wish to propose items of business at an Annual Meeting of Comerica's shareholders. For the 2010 Annual Meeting of Shareholders, notice must be received by Comerica's Corporate Secretary no later than the close of business on February [       ], 2010 and no earlier than the close of business on January [       ], 2010. If, however, Comerica moves the Annual Meeting of Shareholders to a date that is more than 30 days before or more than 60 days after the date which is the one year anniversary of this year's Annual Meeting date (i.e., May 19, 2009), Comerica must receive your notice no earlier than the close of business on the 120th day prior to the new Annual Meeting date and no later than the close of business on the later of the 90th day prior to the new Annual Meeting date or the 10th day following the day on which Comerica first made a public announcement of the new Annual Meeting date.

Comerica's bylaws contain additional requirements for shareholder proposals. A copy of Comerica's bylaws can be obtained by making a written request to the Corporate Secretary.

How can shareholders nominate persons for election as directors at the 2010 Annual Meeting?

All shareholder nominations of persons for election as directors must comply with applicable laws and regulations, as well as Comerica's bylaws, and must be submitted in writing to the Corporate Secretary, Comerica Incorporated, Comerica Bank Tower, 1717 Main Street, MC 6404, Dallas, Texas 75201.

Corporate Secretary no later than the close of business on February [       ], 2010 and no earlier than the close of business on January [       ], 2010.

If, however, Comerica moves the Annual Meeting of Shareholders to a date that is more than 30 days before or more than 60 days after the date which is the one year anniversary of this year's Annual Meeting date (i.e., May 19, 2009), or if a special meeting of shareholders is called for the purpose of electing directors, Comerica must receive your notice no earlier than the close of business on the 120th day prior to the meeting date and no later than the close of business on the later of the 90th day prior to the meeting date or the 10th day following the day on which Comerica first made a public announcement of the meeting date (and, in the case of a special meeting, of the nominees proposed by the Board of Directors to be elected at such meeting).

If Comerica increases the number of directors to be elected to the Board at the Annual Meeting and there is no public announcement naming all of the nominees for director or specifying the size of the increased Board at least 100 days prior to the first anniversary of the immediately preceding year's Annual Meeting, then Comerica will consider your notice timely (but only with respect to nominees for any new positions created by such increase) if Comerica receives your notice no later than the close of business on the 10th day following the day on which Comerica first makes the public announcement of the increase in the number of directors.

In addition, Article III, Section 12 of the bylaws requires a nominee for election or reelection as a director of Comerica to complete and deliver to the Corporate Secretary (in accordance with the time periods described above, in the case of director nominations by shareholders) a written questionnaire prepared by Comerica with respect to the background and qualification of the person and, if applicable, the background of any other person or entity on whose behalf the nomination is being made.

A nominee also must make certain representations and agree that he or she (A) will abide by the requirements of Article III, Section 13 of the bylaws (concerning, among other things, the required tendering of a resignation by a director who does not receive a majority of votes cast in an uncontested election), (B) is not and will not become a party to (1) any agreement, arrangement or understanding with, and has not given any commitment or assurance to, any person or entity as to how, if elected as a director of Comerica, he or she will act or vote on any issue or question (a "Voting Commitment") that has not been disclosed to Comerica or (2) any Voting Commitment that could limit or interfere with his or her ability to comply, if elected as a director of Comerica, with his or her fiduciary duties under applicable law, (C) is not and will not become a party to any agreement, arrangement or understanding with any person or entity other than Comerica with respect to any direct or indirect compensation, reimbursement or indemnification in connection with service or action as a director that has not been disclosed, and (D) in his or her individual capacity and on behalf of any person or entity on whose behalf the nomination is being made, would be in compliance, if elected as a director of Comerica, and would comply with all applicable publicly disclosed corporate governance, conflict of interest, confidentiality and stock ownership and trading policies and guidelines of Comerica.

How many copies of the annual report and proxy statement should I receive?

The SEC has adopted rules concerning the delivery of disclosure documents. The rules allow us to send a single set of any annual report, proxy statement, proxy statement combined with a prospectus, or information statement to any household at which two or more shareholders reside if they share the same last name or we reasonably believe they are members of the same family. This procedure is referred to as "Householding." These rules benefit both Comerica and you. They reduce the volume of duplicate information received at your household and help Comerica reduce expenses. Each shareholder subject to Householding will continue to receive a separate proxy card or voting instruction card.

Comerica will deliver promptly upon written or oral request a separate copy of the annual report or proxy statement, as applicable, to a shareholder at a shared address to which a single copy of the document was delivered. If you received a single set of disclosure documents for the current year, but you would prefer to receive your own copy this year, you may direct requests for separate copies to the Corporate Secretary.

If you are a registered shareholder who resides at the same address as another shareholder and you would prefer to receive your own set of the annual report and/or proxy statement in future years, you may contact our transfer agent, Wells Fargo Shareowner Services, at (877) 602-7615. You will need to enter your account number and Comerica number 114. Alternatively, you may write to our transfer agent at the following address: Wells Fargo Shareowner Services, Attn: Householding, P.O. Box 64854, St. Paul, MN 55164-0854. If you hold your shares in street name, you may revoke your consent to Householding by contacting your brokerage firm, bank or other nominee or by following the directions set forth on the voting instruction card you received with the proxy materials. If you are currently receiving multiple copies of the annual report and/or proxy statement and want to receive only a single copy in the future through Householding, follow the same instructions set forth above for registered shareholders or street name holders, as applicable.

---

Is this year's proxy statement available electronically?

Yes. You may view this proxy statement, as well as the 2008 annual report, electronically by going to www.ematerials.com/cma and clicking on the document you wish to view, either the proxy statement or annual report.

---

Can I receive future annual reports and proxy statements electronically instead of receiving paper copies through the mail?

Yes. If your shares are registered directly in your name (i.e., you do not hold them in street name) and you have access to the Internet, you can receive Comerica's annual report and proxy statement over the Internet rather than in printed form. Enrolling in this service will take just a few minutes of your time. It will give you faster delivery of the documents and will save Comerica the cost of printing

and mailing. To agree to access the electronic versions of Comerica's annual report and proxy statement instead of receiving the printed versions by mail, go to www.ematerials.com/cma and follow the instructions under Request Meeting Materials. Have your proxy card and the last four digits of your Social Security Number or Tax Identification Number available when you access the website. If you agree to electronic delivery, once the annual report and proxy statement are available on the website, we will email you a notice with the website address that you should use to access the information and to receive voting instructions. Paper copies of the annual report and proxy statement would not be sent unless you request them. Comerica also may choose to send one or more items to you in paper form despite your consent to receive them electronically.

If you hold your shares in street name, you should contact your brokerage firm, bank or other nominee to determine the process for receiving Comerica's annual report and proxy statement over the Internet rather than in printed form.

By consenting to electronic delivery, you are stating that you currently have access to the Internet and expect to have access in the future. If you do not have access to the Internet, or do not expect to have access in the future, please do not consent to electronic delivery because Comerica may rely on your consent and not deliver paper copies of future Annual Meeting materials. In addition, if you consent to electronic delivery, you will be responsible for the costs associated with electronic access, such as usage charges from Internet access providers and telephone companies, in connection with the electronic delivery of the annual report and proxy statement.

Section 16(a) of the Securities Exchange Act of 1934 ("Exchange Act") requires that Comerica's directors, executive officers and persons who own more than ten percent of a registered class of Comerica's equity securities file reports of stock ownership and any subsequent changes in stock ownership with the SEC and the New York Stock Exchange not later than specified deadlines. Based solely on its review of the copies of such reports received by it, or written representations from certain reporting persons, Comerica believes that, during the year ended December 31, 2008, each of its executive officers, directors and greater than ten percent shareholders complied with all such applicable filing requirements.

COMPENSATION OF EXECUTIVE OFFICERS

COMPENSATION DISCUSSION AND ANALYSIS

Executive Summary

2008 was a year of unprecedented changes in the financial services industry. Mounting job losses and an economy headed deeper into recession dampened business and consumer confidence. Although Comerica was not immune to these challenges, the Company's performance for 2008 exceeded the performance of many of our peers.

In addition, our compensation decisions reflected both the challenges of this extraordinary economic environment and Comerica's success in navigating them. These included:

•

Freezing the base salaries of named executive officers for 2009; and



•

Reducing to zero the annual cash incentive earned by the Chief Executive Officer and replacing that incentive with a grant of restricted stock that vests in five years in order to further align his incentives with long-term performance.

Objectives and Elements of Comerica's Compensation Program

The overall objectives of Comerica's executive compensation program are to attract, motivate, reward and retain superior executive talent, particularly in the current economic climate, where the recruiting and retention of top performers is of utmost importance. Comerica believes that in order to achieve such objectives, its programs must be competitive with executive compensation arrangements generally provided to other executive officers in the financial services industry. At the same time, Comerica believes it is important to align management incentives with shareholder interests. The various components of Comerica's executive compensation program are designed to maintain the focus of our executive officers on business goals over immediate, short-term and long-term horizons and to be competitive with our peers.

The principal components of executive compensation are base salaries, short and long-term cash management incentive awards, long-term stock incentive awards, retirement benefits and a limited number of perquisites. Certain executives, including the named executive officers, also have change in control agreements (described in the "Employment Contracts and Severance or Change in Control Agreements" section below).

Our Compensation Consultant

Comerica's compensation program is under the direction of the Governance, Compensation and Nominating Committee (the "Committee"), which is composed solely of independent directors meeting the independence requirements of the Securities and Exchange Commission and the New York Stock Exchange.⁽¹⁾ The Governance, Compensation and Nominating Committee has retained Hewitt Associates LLC ("Hewitt"), a nationally known executive compensation consulting firm, with respect to executive and director compensation matters. Hewitt provides market analyses and consulting services on compensation matters to such committee. Hewitt is independent and has not been separately retained by Comerica to provide any other services.

(1)

The Governance, Compensation and Nominating is a combination of two prior committees of the Board of Directors of Comerica: the Compensation Committee and the Corporate Governance and Nominating Committee. Those committees were combined into one committee, effective immediately after the annual shareholders meeting held on May 20, 2008.

Table of Contents

The market analyses Hewitt provides for the Governance, Compensation and Nominating Committee's information includes detailed compensation information, derived from proxy statements, for the named executive officers at the 13 domestic bank holding companies in Comerica's peer group (described below in the "Management Incentive Plan" section). The analysis reflects individual compensation elements (e.g., base salary, bonus, value of option grants, etc.) and total compensation and is arrayed to show Comerica's position relative to the peer group for each element and in total. The Governance, Compensation and Nominating Committee reviews this data each year and uses the information to assist in making compensation decisions for Comerica's named executive officers.

Base Salaries

Competitive base salaries serve our compensation philosophy of attracting and retaining executives who are critical to executing our long-term strategy. Comerica pays base salaries to compensate executive officers for current service. The Governance, Compensation and Nominating Committee annually considers possible adjustments to salaries based on such officers' individual performance and contribution to the Company's success.

Base salary increases for Mr. Babb, the Chief Executive Officer, are made by the Governance, Compensation and Nominating Committee without any recommendations from management (except that in 2009, management recommended a salary freeze for all the named executive officers, including the Chief Executive Officer). When applicable, base salary increases for the named executive officers other than the Chief Executive Officer are made by the Governance, Compensation and Nominating Committee upon the recommendation of Mr. Babb. In determining increases, if any, to base salaries, the Governance, Compensation and Nominating Committee considers the recommendations of Mr. Babb (in the case of the named executive officers other than himself), historical salary and total compensation levels for the individual, economic factors and information provided by Hewitt, as discussed in the "Our Compensation Consultant" section above. Although the Governance, Compensation and Nominating Committee froze the salaries of all named executive officers in 2009, there were salary increases in 2008, in large part because the U.S. economy was not in the same state of turmoil at the beginning of 2008 that it was in at the beginning of 2009. Specific factors considered in determining the increased amounts for 2008 included:

•

A comparison of Comerica salaries for the named executive officers to comparable positions within Comerica's peer group (including expected 2008 salary increases for executives at those other organizations, which were projected to range between two percent and four percent); and



•

Individual performance (goals for each executive may vary based on his or her responsibilities, but generally include objectives related to business unit performance, people management and contribution to the achievement of corporate goals).

Effective as of the beginning of 2008, each named executive officer received the salary increases set forth in the table below:

15

Table of Contents

In 2009, however, management recommended, and the Governance, Compensation and Nominating Committee approved, a salary freeze for all named executive officers, including the Chief Executive Officer, for 2009.

Management Incentive Plan

Comerica maintains a Management Incentive Plan for senior officers (i.e., Senior Vice President level officers and above, comprised of approximately 420 individuals, including the named executive officers) that provides cash incentives that are driven by Comerica's performance. Under the Management Incentive Plan, there are two parts to the incentive:

•

An award based on performance over a one-year period, and



•

An award based on performance over a three-year period.

The annual management incentive awards are intended to reward the attainment of short-term goals, while the three-year management incentive awards are intended to reward sustained performance over the long-term. Overall, awards under the Management Incentive Plan serve our compensation philosophy of aligning the interests of our top executives with those of our shareholders.

Currently, the primary measures of performance under the Management Incentive Plan are based on return on common equity and earnings per share growth in relation to Comerica's peer group. These two metrics have been chosen because they are two of the most commonly used metrics by investors and analysts to evaluate a bank's performance. In addition, unlike other metrics that may be calculated differently, return on common equity and earnings per share growth have a generally prescribed formula, allowing these metrics to be easily validated and compared to Comerica's peers. Comerica believes the use of measures that are well understood, transparent and based on the audited financial results of the Company are the foundation of a responsible incentive program that rewards performance without encouraging participants to take excessive risk.

The 2008 peer group consisted of the following 13 domestic bank holding companies:

The Governance, Compensation and Nominating Committee has determined that this peer group is the appropriate one to use for purposes of the Management Incentive Plan because the group consists of the domestic bank holding companies that the Governance, Compensation and Nominating Committee believes are the most comparable to Comerica in business focus and size. As of December 31, 2008 Comerica's assets totaled approximately $67.5 billion as compared with the peer group, which ranged from approximately $54 billion to $291 billion in assets.

Table of Contents

At the beginning of each year, the Governance, Compensation and Nominating Committee determines the funding formula that will be applied to management incentive awards under the Management Incentive Plan, depending on Comerica's ranking as compared with its peer group. The 2008 funding formula was based on one-year return on common equity and one-year earnings per share growth (for the short-term incentive) and on three-year average return on common equity and three-year average earnings per share growth (for the long-term incentive).

The Governance, Compensation and Nominating Committee, in accordance with the terms of the Management Incentive Plan, may make adjustments to return on equity and earnings per share growth when such adjustments are necessary to fairly compare Comerica to its peers (such as for restructuring costs due to merger and acquisition activity or, with respect to periods prior to the effective date of Statement of Financial Accounting Standards No. 123R, to expense stock options for bank holding companies in the peer group).

Each of the named executive officers had a maximum annual and three-year incentive opportunity under the Management Incentive Plan for the performance periods ended December 31, 2008 (which represented a percentage of the respective named executive officer's base salary) as set forth in the table below:

The maximum percent opportunities were developed using market data for comparable positions at other financial organizations to ensure a competitive bonus opportunity, given maximum performance. The maximum opportunity increases at each level, reflecting an increase in responsibility and in market pay for comparable positions. The Governance, Compensation and Nominating Committee reviews and approves the maximum funding by level each year.

The Management Incentive Plan provides a greater maximum opportunity for the short-term incentive than for the long-term incentive because the long-term incentive under the Management Incentive Plan is balanced by the Long-Term Incentive Plan (discussed in the "Stock-Based Awards Under the Long-Term Incentive Plan" section below), which places more of an emphasis on long-term goals. In this way, Comerica's overall executive compensation program rewards high performance in a balanced manner, both short-term and long-term. This is important because the balanced approach discourages unnecessary and excessive risk-taking while aligning the interests of management with those of the shareholders.

The maximum incentive opportunity amount under the Management Incentive Plan is used as the baseline for downward adjustments, depending on Comerica's performance as compared to its peers. The overall maximum incentive amount could only be attained if Comerica ranked number one in both return on equity and earnings per share growth in relation to the peer group for the short-term and long-term performance periods, as set forth in the funding formula below.

For each of the Management Incentive Plan performance measurements, the funding formula assigns specific incentive payouts for each ranking (one through fourteen) that Comerica could achieve as compared to its peer group. If Comerica ranks poorly in relation to its peers on the

17

---

Table of Contents

funding formula criteria, executives will receive less of an incentive, or no incentive at all, depending on what the formula dictates. For example:

•

For the annual performance period ended December 31, 2002, the named executive officers received no annual incentive (excluding a hiring bonus for a new employee) because Comerica ranked 17 out of 18 as compared to its peers for one-year return on average common equity and one-year earnings per share growth; and



•

For the three-year performance period ended December 31, 2004, the named executive officers received no long-term incentive because Comerica ranked 15 out of 15 as compared to its peers for the three-year average return on average common equity and three-year average earnings per share growth.

There is no discretion to increase a bonus for named executive officers, only discretion to decrease a bonus for a particular executive if he or she has not performed at an optimal level. Comerica believes that this strict formulaic approach to incentives is important because it causes executives to be held accountable for corporate performance.

The 2008 funding formula, based on Comerica's rank in comparison to firms in our peer group, was as follows:

In January 2009, Comerica's independent accountants, at the request of the Governance, Compensation and Nominating Committee, issued a report applying certain agreed-upon procedures to assist the Governance, Compensation and Nominating Committee in determining that the computations for the incentive awards issued for periods ended December 31, 2008 were made in conformity with the Management Incentive Plan. The report addressed Comerica's 2008 rankings in relation to the peer group for the annual and three-year performance periods, using the measurement components set by the Governance, Compensation and Nominating Committee. In order to facilitate making the peer comparison computations in a timely manner, Comerica's results are measured over calendar year-end periods, whereas peer data is taken from periods ending in the third calendar quarter. For example, Comerica's performance for the annual performance period that began on January 1, 2008 and ended on December 31, 2008 would be compared against our peers' performance for the four quarters that began on October 1, 2007 and ended on September 30, 2008.

For the performance periods ended on December 31, 2008, our results were as follows:

•

Comerica's one-year adjusted return on common equity was 3.79%, which placed Comerica at number nine among its peer group;

18

---

Table of Contents

•

Comerica's one-year adjusted earnings per share growth was (70.88%), which placed Comerica at number ten among its peer group;



•

Comerica's three-year adjusted average return on common equity was 11.51%, which placed Comerica at number six among its peer group; and



•

Comerica's three-year adjusted average earnings per share growth was (27.58%), which placed Comerica at number ten among its peer group.

At its January 27, 2009 meeting, the Governance, Compensation and Nominating Committee discussed the 2008 financial results described above and the incentive pool calculated based on those results. Because Comerica outperformed many of its peers for the performance period ended December 31, 2008, the Management Incentive Plan funding formula resulted in incentive payouts for both the annual and three-year performance periods. However, in light of the current U.S. economic environment, the Governance, Compensation and Nominating Committee also considered whether it was appropriate to reduce incentives below the amount earned under the plan. In making its determination, the Committee considered the following:

•

Comerica's Management Incentive Plan is a shareholder approved plan. The program is designed to focus senior leadership on the delivery of short and longer-term results that benefit shareholders, and the measures used to quantify those results are well understood, transparent and based on audited financial results.



•

Comerica's Management Incentive Plan has been historically applied in a consistent and honest manner that only rewards positive performance relative to peers. Comerica cannot increase the incentive funding pool for named executive officers on a discretionary basis. In years when Comerica's performance has been lower relative to peers, the funding has reflected that lower level of performance (including annual or three-year payouts of zero in some years, as discussed above).



•

Funding under Comerica's Management Incentive Plan is based primarily on return on common equity and earnings per share growth. Returns to taxpayers in the form of dividends paid under the Capital Purchase Plan ("CPP") created under the Emergency Economic Stabilization Act of 2008 are deducted before return on common equity and earnings per share growth are calculated. Therefore, Comerica's plan is based on post-CPP performance relative to peers, and the funding is earned based on Comerica outperforming its peers. (See "Executive Compensation Implications of the Emergency Economic Stabilization Act" and "The American Recovery and Reinvestment Act of 2009" below for a more detailed discussion of the CPP.)



•

The Management Incentive Plan funding for 2008 was based on Comerica's performance for the annual performance period that began on January 1, 2008 and ended on December 31, 2008, as compared with peer performance for the four quarters that began on October 1, 2007 and ended on September 30, 2008 (as discussed earlier in this "Compensation Discussion and Analysis" section). Because the financial services industry generally faced a particularly difficult fourth quarter in 2008, Comerica's relative performance was negatively impacted by the different measurement periods. If peer calendar year results had been compared to Comerica's calendar year results, Comerica's rankings relative to peers would have been even higher, leading to greater Management Incentive Plan payouts under the formula described above.



•

Reduction of incentives earned under the Management Incentive Plan might discourage Comerica's key employees from striving to perform at their utmost during a time when Comerica's most important assets, its people, need to be present, engaged and committed to efforts designed to see the Company through the current turbulent cycle.

Table of Contents

After discussion and consideration of the factors described above, the Committee made the following determinations under the Management Incentive Plan:

•

Awards were generally based on the performance results of the pre-established funding formula, which led to total incentives lower than those paid in the prior year for all of the named executive officers (see the chart below); but



•

In recognition of the challenges now faced by the Company and its industry, the Committee, at the request of the Chief Executive Officer, decided to reduce to zero the annual cash award to the Chief Executive Officer under the Management Incentive Plan for the period ended December 31, 2008. Instead, the Committee granted him, on January 27, 2009, shares of restricted stock with a five year cliff vesting schedule equivalent to the value of what he would have received for the annual performance incentive (see below under "Stock-Based Awards under the Long-Term Incentive Plan"). However, in order to ensure an appropriate mix between the Chief Executive Officer's cash and equity-based compensation, the Committee determined to provide him with the cash incentive earned under the plan for the three-year period ended on December 31, 2008.

The Committee concluded that this approach to the Chief Executive Officer's compensation would better align his interests with those of shareholders by encouraging him to focus on performance for a longer five-year period while rewarding our named executive officers for the Company's performance during this challenging period.

Awards to the named executive officers for the one-year and three-year performance periods ended December 31, 2008 under the Management Incentive Plan, as compared with awards for the periods ended December 31, 2007, are set forth in the table below:

Stock-Based Awards under the Long-Term Incentive Plan

Comerica's officers and employees, including all of the named executive officers, are eligible to receive stock-based awards under Comerica's Long-Term Incentive Plan, which was approved at the May 16, 2006 annual meeting of shareholders. The Long-Term Incentive Plan serves our compensation philosophy of aligning the interests of our officers and employees with those of shareholders by providing an incentive to contribute to the long-term goals of Comerica. Equity-based compensation also serves our overall compensation philosophy by assisting in the attraction and retention of qualified employees.

Awards in 2008 consisted of stock option and restricted stock grants, which were made as part of the total compensation package. We grant both stock options and restricted stock because they serve different aspects of our compensation philosophy:

•

Stock options encourage the named executive officers to achieve long-term goals because they only have value to the recipient if there are gains in the stock price. For example, stock options granted in 2008 vest ratably over four years, and no gain is realizable prior to vesting; therefore, stock options give our executives strong incentives to improve long-term financial performance and to increase shareholder value.



•

Restricted stock serves a dual purpose, both encouraging the named executive officers to achieve high long-term performance (because the restricted stock will be worth more if the

20

---

Table of Contents

stock price increases) and serving as an important retention tool because it normally will have some value even if the stock price has remained flat or declined. For example, the 2008 restricted stock grants to the named executive officers vest five years from the date of the grant, sometimes referred to as "cliff vesting." Because the executive officer loses rights in respect of the restricted stock grant if he or she leaves Comerica prior to the expiration of the five-year period, the executive officer is motivated to remain with Comerica long-term.

Comerica believes that the combination approach of granting stock options and restricted stock best allows us to pursue our compensation philosophy of successfully retaining and motivating our named executive officers.

Grants of stock options and restricted stock to the named executive officers are allocated from a pool of stock that is created each year based on several factors including:

•

Targeted awards as a percent of each officer's base salary;



•

The number of shares available for grant under the Long-Term Incentive Plan; and



•

Analysis of Comerica's share usage compared with industry benchmarks.

Distribution from the pool to the named executive officers is based on the Governance, Compensation and Nominating Committee's assessment of the officer's future potential to contribute to Comerica (as evidenced, in part, by individual performance and levels of responsibility) and of competitive data.

Comerica generally allocates the awards between stock options and restricted stock by determining a dollar value to be granted to an individual, and then apportioning part of that dollar value to stock options and the other portion to restricted stock. With respect to all the named executive officers other than himself, the Chief Executive Officer makes grant recommendations to the Governance, Compensation and Nominating Committee. The Governance, Compensation and Nominating Committee considers his recommendations, historical total compensation and grants made to the individuals and survey information provided by Comerica's independent compensation consultant, Hewitt, in making its grant determinations. With respect to the Chief Executive Officer, the Governance, Compensation and Nominating Committee typically determines the amount of his grant without receiving any recommendation from management, although it does consider historical grant data as well as survey information provided by Hewitt. This survey information includes detailed peer compensation data, such as the value of option and restricted stock grants and Long-Term Incentive Plan payments, as discussed in the "Our Compensation Consultant" section above. See also the "Management Incentive Plan" section above for additional information on additional shares of restricted stock granted to the Chief Executive Officer in 2009 in lieu of his 2008 annual incentive under the Management Incentive Plan and the "Perquisites" section below for additional information on certain restricted stock awards granted in connection with Comerica's corporate headquarters relocation.

Stock Granting Policy

In 2008, grants to the named executive officers were made at the regularly scheduled Compensation Committee⁽²⁾ meeting on January 22, 2008 in accordance with Comerica's Stock Granting Policy. The Stock Granting Policy stipulates that, in general, Comerica will make stock-based grants to eligible employees, including the named executive officers, once per year at the first regularly scheduled meeting of the Governance, Compensation and Nominating Committee that calendar year. The grant date is the date of such regularly scheduled Governance, Compensation and Nominating Committee meeting, unless (a) such meeting does not occur on a day in which the New York Stock Exchange is open for trading ("NYSE Trading Day") or (b) such meeting does not occur during a Trading Window (as defined in Comerica's Insider Trading Policy).

The Compensation Committee and the Corporate Governance and Nominating Committee were combined into one committee, the Governance, Compensation and Nominating Committee, effective immediately after the annual shareholders meeting held on May 20, 2008.

Table of Contents

In accordance with the Stock Granting Policy, the Compensation Committee granted the named executive officers stock options and restricted stock on January 22, 2008, at the first regularly-scheduled meeting of the Compensation Committee in 2008. The meeting was held on a NYSE Trading Day and fell within a regularly scheduled Trading Window. The exercise price for the 2008 stock options is the closing price of Comerica's common stock on the grant date and the stock options vest ratably over four years. The 2008 restricted stock grants to the named executive officers, as previously mentioned, are subject to five-year cliff vesting.

Comerica also may award stock-based grants during the year to newly hired employees, including newly hired named executive officers, as part of their compensation package. Under the Stock Granting Policy, in most cases, the grant date would depend on the named executive officer's actual start date. For a named executive officer whose start date fell between the first and the 15th day of the month, the Governance, Compensation and Nominating Committee would typically set the grant date as the last day of such month or, if the last day of such month were not a NYSE Trading Day, then the first NYSE Trading Day immediately preceding the last day of such month. If the start date fell between the 16th and the last day of the month, the grant date would be on the 15th day of the following month or, if the 15th day of the following month was not a NYSE Trading Day, then the first NYSE Trading Day immediately preceding the 15th day of such month. However, if the foregoing grant dates had already passed before a grant was made (because, for example, the Governance, Compensation and Nominating Committee did not meet shortly before the time of the employee's start date), then the Stock Granting Policy provides that the Governance, Compensation and Nominating Committee would make such grant at a regularly scheduled meeting, and the grant date would be the date of such regularly scheduled Governance, Compensation and Nominating Committee meeting unless (a) such meeting did not occur on a NYSE Trading Day or (b) such meeting did not occur during a Trading Window. In either such case, the grant date would be the first NYSE Trading Day immediately following the regularly scheduled meeting of the Governance, Compensation and Nominating Committee that also occurred in a Trading Window. None of the named executive officers was newly hired in 2008.

Under the Stock Granting Policy, off-cycle option or restricted stock grants (such as for special recognition or retention purposes) are made to named executive officers by the Governance, Compensation and Nominating Committee at a regularly scheduled meeting. If the grants are approved, the grant date is the date of the applicable meeting, unless (a) such meeting did not occur on a NYSE Trading Day or (b) such meeting did not occur during a Trading Window. At the regularly scheduled meeting of the Governance, Compensation and Nominating Committee that occurred on November 18, 2008, the Committee approved an off-cycle grant of restricted stock to Mr. Buttigieg in the amount of 14,870 shares in connection with the relocation of Comerica's corporate headquarters. November 18, 2008 was a NYSE Trading Day and fell in the Company's Trading Window and as such, the grant date was established on that same date. See the "Perquisites" section below for more information regarding this grant.

Employee Stock Purchase Plan

Comerica has an Employee Stock Purchase Plan ("ESPP") which provides participating employees a convenient and affordable way to purchase shares of Comerica common stock without being charged a brokerage fee. This encourages share ownership, which serves our compensation philosophy of aligning the interests of Comerica's employees with those of its shareholders. For further details on the terms on which our named executive officers participate in the ESPP, please see the 2008 Summary Compensation Table, and footnote 7 to the 2008 Summary Compensation Table, below.

Stock Ownership Guidelines

In order to pursue our compensation philosophy of aligning the interests of our senior officers with those of the shareholders, we have implemented stock ownership guidelines that encourage senior

22

---

Table of Contents

officers to own a significant number of shares of Comerica's common stock. The stock ownership guidelines are calculated based on the senior officer's annual base salary times a certain multiple. Comerica encourages its senior officers to achieve the targeted stock ownership levels within five years of being promoted or named to the applicable senior officer position. For purposes of the stock ownership guidelines, stock ownership includes unvested shares of restricted stock and all other shares owned by the executive, including shares held in trust where the executive retains beneficial ownership. However, outstanding stock option awards, whether vested or unvested, are not applied toward the stock ownership calculation for purposes of meeting the stock ownership guidelines.

In 2008, Comerica revised its stock ownership guidelines by reducing the employee population covered by the guidelines to only include Senior Vice Presidents at a salary grade of BE2 or higher. This change was made to bring Comerica's stock ownership guidelines more in line with the practice of peers. The population subject to share ownership guidelines includes approximately 116 employees, including the named executive officers. As of December 31, 2008, all named executive officers who had held their current title for at least five years had met their respective stock ownership guideline levels with the exception of Ms. Acton. However, Ms. Acton's ownership in Comerica stock increased by approximately 36% (16,138 shares) from December 31, 2007 to December 31, 2008.

OFFICER STOCK OWNERSHIP GUIDELINES

Retirement Benefits

Comerica provides retirement benefits to attract and retain employees and to encourage employees to save money for their retirement.

The Company sponsors a tax-qualified defined benefit retirement plan that provides a retirement benefit based on a salaried employee's years of service and final average monthly pay. Final average monthly pay is a participant's highest aggregate monthly compensation for 60 consecutive calendar months within the last 120 calendar months before the earlier of retirement or separation from service, divided by 60. Employees hired on or after January 1, 2007 are not eligible to participate. The Company also sponsors a Benefit Equalization Plan for Employees of Comerica Incorporated (the "SERP") who participate in the tax qualified defined benefit retirement plan to restore benefits that are capped under such plan due to Internal Revenue Service ("IRS") limits on annual compensation, annual benefit amounts and the absence of top-heavy accruals to key employees if the plan becomes top-heavy. Comerica provides the SERP in keeping with competitive practices in the external marketplace.

The Company also maintains a 401(k) savings plan for all employees. Prior to 2007, Comerica provided two types of matching with respect to participant contributions. The first type of matching was called a core match. It consisted of a 50% match on the first $1,000 of qualified compensation the participant contributed, plus a 25% match on the next $2,000 of qualified compensation the participant contributed up to a maximum contribution of $1,000. The second type of matching was called a performance-based match. If Comerica met its financial goals, 401(k) savings plan contributors received a performance-based match in addition to the core match. The match amount varied and was made on contributions up to three percent of an individual's salary subject to the IRS annual compensation limit. The match amount was determined based on Comerica's overall

23

---

Table of Contents

performance compared to that of its peer banks. The matched amounts vested at the end of the calendar year.

Effective January 1, 2007, Comerica implemented a new Safe Harbor 401(k) plan with an enhanced match to place Comerica in a more competitive position relative to peers and to assist with recruiting and retention of employees. The 401(k) savings plan match was revised by discontinuing the core and performance-based matches and replacing them with a 100% match on the first four percent of a participant's qualified earnings, subject to the IRS annual compensation limit of $230,000 in 2008, that have been contributed to the 401(k) savings plan. The match is placed in the employee's current investment selections and vests immediately rather than at the end of the calendar year. Under both the old and the new system, the matching criteria are the same for all employees, so the named executive officers do not receive a benefit that is not also available to other employees.

A salaried employee hired on or after January 1, 2007 does not participate in the defined benefit pension plan but is eligible for a company contribution pursuant to the Defined Contribution (DC) Feature under the 401(k) savings plan. The annual company contribution pursuant to the DC Feature is made on behalf of participants who complete at least 1,000 hours of service during the plan year and equals a percentage of compensation that is based on the participant's total age and years of service points as follows:
