"The financial results highlight our positive financial performance in the first quarter," said Ralph W. Babb Jr., chairman and chief executive officer. "Our net interest margin rose seven basis points from the fourth quarter of 2006. Credit quality was solid across all markets and expenses were well controlled."

    First Quarter 2007 Compared to Fourth Quarter 2006
     - On an annualized basis, excluding Financial Services Division loans,
       average loans increased six percent, led by growth of 15 percent in the
       Western market, five percent in the Texas market, four percent in the
       Florida market, three percent in Other markets and 18 percent in the
       International market, with the Midwest market down one percent. The
       Texas loan growth, impacted by pay downs in January, rebounded in
       February and March with low double-digit annualized average loan growth
       rates.
     - The net interest margin was 3.82 percent in the first quarter 2007, an
       increase of seven basis points from 3.75 percent in the fourth quarter
       2006.
     - Net credit-related charge-offs were $19 million, or 16 basis points as
       a percent of average total loans, for the first quarter 2007, compared
       to $23 million, or 19 basis points as a percent of average total loans,
       for the fourth quarter 2006.  Fourth quarter 2006 included a $9 million
       charge-off to reflect the estimated fair value of a portfolio of loans
       related to manufactured housing that were transferred to held-for-sale.
     - Noninterest expenses, excluding the provision for credit losses on
       lending-related commitments, decreased $52 million from the fourth
       quarter 2006, the detail of which is discussed in "Noninterest
       expenses" below. Employee levels from continuing operations (FTE)
       decreased slightly from December 31, 2006, to March 31, 2007. This
       decrease occurred even as nine new banking centers were opened in the
       first quarter 2007.
     - The provision for income taxes decreased primarily due to a fourth
       quarter 2006 adjustment to tax reserves of $22 million.  Refer to "Tax-
       related items" below for further discussion.
     - Open market share repurchases in the first quarter 2007 totaled 3.4
       million shares, or two percent of total shares outstanding at
       December 31, 2006.


    Net Interest Income Stable and Net Interest Margin Rises

      (dollar amounts in millions)      1st Qtr '07  4th Qtr '06  1st Qtr '06

      Net interest income                     $502        $502        $479

      Net interest margin                     3.82 %      3.75 %      3.80 %

      Selected average balances:
       Total earning assets                $53,148     $53,289     $50,977
       Total loans                          48,896      48,568      46,479
       Total loans, excluding FSD loans
        (primarily low-rate)                47,327      46,659      43,570

       Total interest-bearing deposits      30,417      30,554      27,589
       Total noninterest-bearing
        deposits                            12,162      12,649      13,609
       Total noninterest-bearing
        deposits, excluding FSD              8,712       8,696       8,926


     - A seven basis point improvement in the net interest margin offset the
       impact of two less days in the first quarter 2007 ($11 million).
       Average earning assets remained relatively stable in the first quarter
       2007, when compared to fourth quarter 2006.
     - The first quarter 2007 net interest margin reflected stable loan yields
       and a decline in deposit rates. The positive impact of lower average
       Financial Services Division loans (primarily low-rate) was essentially
       offset by a decline in Financial Services Division noninterest-bearing
       deposits.

Steady Noninterest Income, Excluding Identified Items

Noninterest income was $203 million for the first quarter 2007, compared to $262 million for the fourth quarter 2006 and $195 million for the first quarter 2006. The $59 million decrease in noninterest income in the first quarter 2007, compared to the fourth quarter 2006, was primarily the result of income of $47 million from the settlement of a Financial Services Division- related lawsuit received in the fourth quarter 2006, a $7 million decrease in income from principal investing and warrants and a $6 million decrease in investment banking fees, partially offset by positive trends in several categories (including fiduciary income, brokerage fees and card fees). Certain categories of noninterest income are highlighted in the table below.

Noninterest Expenses Well Controlled

Noninterest expenses were $407 million for the first quarter 2007, compared to $457 million for the fourth quarter 2006 and $429 million for the first quarter 2006. The $50 million decrease in noninterest expenses in the first quarter 2007, compared to the fourth quarter 2006, reflected decreased salaries expense of $25 million. The decrease in salaries expense was due primarily to decreased incentives tied to performance, including the fourth quarter 2006 gain on the sale of Munder, contract labor costs associated with technology-related projects, and severance, partially offset by an increase in share-based compensation expense. The increase in share-based compensation expense reflected the annual award of restricted stock to retirement-eligible employees, granted in the first quarter each year, which must be expensed in the period granted. Also reflected in the decrease in noninterest expenses was a decrease in interest on tax liabilities of $15 million (see "Tax-related items" below), and a fourth quarter 2006 contribution of $10 million to the Comerica Charitable Foundation.

    Certain categories of noninterest expenses are highlighted in the table

Tax-related Items

On January 1, 2007, Comerica adopted the provisions of FASB Interpretation No. 48, "Accounting for Uncertainty in Income Taxes - an interpretation of FASB Statement No. 109," (FIN 48). FIN 48 permits Comerica to prospectively change its accounting policy as to where interest on tax liabilities is classified on the consolidated statements of income. Effective January 1, 2007, Comerica changed its accounting policy and began to classify interest on tax liabilities in the "provision for income taxes" on the consolidated statements of income. Prior to January 1, 2007, interest on tax liabilities was classified in "other noninterest expenses." In the first quarter 2007, the Securities and Exchange Commission requested that the American Institute of Certified Public Accountants clarify that an election to change classification under the Interpretation could only be prospective. Therefore, for all prior periods presented, interest on tax liabilities remained classified in "other noninterest expenses" on the consolidated statements of income. The provision for income taxes included interest on tax liabilities of $1 million for the first quarter 2007. Noninterest expenses in 2006 included $38 million of interest on tax liabilities, including $15 million in the fourth quarter 2006 and $26 million in the first quarter 2006.

Fourth quarter 2006 reflected a charge to Comerica's combined tax and related interest reserves for disallowed loan benefits related to a series of loans to foreign borrowers of $31 million after-tax based on settlements discussed with the Internal Revenue Service. Of the total, $22 million was included in the provision for income taxes and $14 million ($9 million after- tax) was for tax-related interest included in other noninterest expenses.

Income from Discontinued Operations

In December 2006, Comerica completed the sale of its stake in Munder to an investor group and recognized an initial after-tax gain from the sale of $108 million, reflected in "income from discontinued operations, net of tax" on the consolidated statements of income. Comerica reports Munder as a discontinued operation in all periods presented; therefore, the after-tax earnings of Munder, including the gain from its sale, are reported as a single item at the bottom of the income statement. The following table summarizes significant items affecting income from discontinued operations, net of tax:

Credit Quality Remained Solid

"Net charge-offs were lower and nonperforming assets were unchanged," said Babb. "We continued to manage our credit risk effectively, particularly the automotive and commercial real estate portfolios. Our people, and the enhanced risk management tools they use, have helped us to maintain solid credit quality in all markets."

     - The provision for loan losses reflected challenges to industries
       located in Michigan (Midwest market), including the automotive
       industry.
     - Fourth quarter 2006 net loan charge-offs included a $9 million charge-
       off to reflect the estimated fair value of a portfolio of loans related
       to manufactured housing that were transferred to held-for-sale.
     - Nonperforming assets remained at the low level of 49 basis points of
       total loans and foreclosed property, compared to the fourth quarter
       2006. During the first quarter 2007, $69 million of loan relationships
       greater than $2 million were transferred to nonaccrual status, an
       increase of $3 million from the fourth quarter 2006.

Balance Sheet and Capital Management

Total assets and common shareholders' equity were $57.5 billion and $5.1 billion, respectively, at March 31, 2007, compared to $58.0 billion and $5.2 billion, respectively, at December 31, 2006. There were approximately 156 million shares outstanding at March 31, 2007, compared to 158 million shares outstanding at December 31, 2006. Open market share repurchases for the current and prior quarter are shown in the following table:

In the first quarter 2007, Comerica generated approximately $145 million of capital from the issuance of trust preferred securities, net of redemptions, and used $100 million of the proceeds to repurchase approximately 1.7 million additional shares.

Comerica's first quarter 2007 estimated tier 1 common, tier 1 and total risk-based capital ratios were 7.47 percent, 8.17 percent and 12.21 percent, respectively.

New Accounting Pronouncements

Comerica adopted FSP 13-2 (Accounting for a Projected Change in the Timing of Cash Flows Related to Income Taxes Generated by a Leveraged Lease Transaction) and FIN 48 (Accounting for Uncertainty in Income Taxes) as of January 1, 2007. The effect of adoption was a reduction to retained earnings of $46 million and a lowering of 2007 income earned on lease financing loans for FSP 13-2 and an increase to retained earnings of $3 million for FIN 48. The effects of FSP 13-2 will reverse over periods ranging from four to 20 years.

Full Year 2007 Outlook

Comerica's outlook for full-year 2007, compared to full-year 2006, is as follows:

     - Mid to high single-digit average loan growth, excluding Financial
       Services Division loans, with flat growth in the Midwest market, and
       low double-digit growth in the Western and Texas markets
     - Average earning asset growth slightly less than average loan growth
     - Average Financial Services Division noninterest-bearing deposits
       remaining at first quarter 2007 level of $3.5 billion. Financial
       Services Division loans will fluctuate in 2007 with the level of
       noninterest-bearing deposits
     - Average full year net interest margin of about 3.75 percent to 3.80
       percent
     - Average net credit-related charge-offs of about 20 basis points of
       average loans, with a provision for credit losses modestly exceeding
       net charge-offs
     - Low single-digit growth in noninterest income, from a 2006 adjusted
       base of $820 million which excludes the Financial Services Division-
       related lawsuit settlement and the loss on sale of the Mexican bank
       charter
     - Flat noninterest expenses, excluding the provision for credit losses on
       lending-related commitments. Outlook reflects anticipated 2007 costs
       associated with the previously announced headquarters move to Dallas,
       Texas (expected to be about $10 million) and tax-related interest in
       2006 (classified in the provision for income taxes in 2007)
     - Effective tax rate of about 32 percent
     - Active capital management within targeted capital ratios (tier 1 common
       of 6.50 percent to 7.50 percent and tier 1 of 7.25 percent to 8.25
       percent)

Business Segments

Comerica's continuing operations are strategically aligned into three major business segments: the Business Bank, the Retail Bank, and Wealth & Institutional Management. The Finance Division also is included as a segment. The financial results below are based on the internal business unit structure of the Corporation and methodologies in effect at March 31, 2007 and are presented on a fully taxable equivalent (FTE) basis. The accompanying narrative addresses first quarter 2007 results compared to fourth quarter 2006.

    The following table presents net income (loss) by business segment.

     - The net interest margin was relatively unchanged, as both loan spreads
       and deposits spreads were relatively stable.
     - Excluding the $340 million decline in the Financial Services Division,
       average loans increased $589 million, or six percent on an annualized
       basis, primarily due to growth in the National Dealer Services, Middle
       Market and Global Corporate Banking business lines.
     - Average deposits increased $193 million, excluding the $593 million
       decline in the Financial Services Division, primarily in the Technology
       and Life Sciences and Global Corporate Banking business lines.
     - Noninterest income decreased $55 million, primarily due to income of
       $47 million from a Financial Services Division-related lawsuit
       settlement in the fourth quarter 2006, lower investment banking fees
       and a negative warrant fair value adjustment in the first quarter 2007.
     - Noninterest expenses decreased $24 million, primarily due to decreases
       in net corporate overhead expenses, incentive compensation and legal
       fees.  Net corporate overhead expenses decreased due to the impact on
       overhead of higher fourth quarter 2006 tax-related interest expense
       (see "Tax-related Items" above) and a fourth quarter 2006 contribution
       to the Comerica Charitable Foundation.

     - The net interest margin of 3.74 percent increased three basis points,
       primarily due to an increase in deposit spreads, partially offset by a
       decline in loan spreads.
     - Average loans remained relatively flat, as increases in small business
       commercial loans were offset by a decline in consumer loans resulting
       from the first quarter 2007 sale of $74 million of manufactured housing
       loans.
     - Average deposits increased $64 million, primarily due to growth in
       customer certificates of deposit.
     - Fourth quarter 2006 net credit-related charge-offs included $9 million
       related to the transfer of the previously mentioned manufactured
       housing loans to held-for-sale.
     - Noninterest expenses decreased $11 million, primarily due to a decrease
       in net corporate overhead expenses (as described in the Business Bank).
     - Opened nine new banking centers in the first quarter 2007.

     - Average loans increased $101 million, or 11 percent on an annualized
       basis.
     - Average deposits decreased $34 million, primarily due to decreased
       noninterest-bearing accounts.
     - Noninterest income increased $4 million, primarily due to increased
       trust fees in the first quarter 2007.
     - Noninterest expenses decreased $10 million, primarily due to a decrease

       primarily due to a decline in loan spreads.
