  * In the fourth quarter 2006, Comerica sold its stake in Munder Capital
    Management (Munder) and reports Munder as a discontinued operation in
    all periods presented.

Income from continuing operations for 2007 was $682 million, or $4.40 per diluted share, compared to $782 million, or $4.81 per diluted share, for 2006. The provision for loan losses was $212 million for 2007, compared to $37 million for 2006. Return on average common shareholders' equity from continuing operations was 13.41 percent for 2007 and 15.11 percent for 2006.

"2007 was a challenging year for the banking industry, including Comerica," said Ralph W. Babb Jr., chairman and chief executive officer. "While we continued to execute our strategy, reflected by strong loan growth, particularly in our high growth markets, challenges in the residential real estate development portfolio affected our performance. Our fourth quarter earnings were largely impacted by an increase in the provision for loan losses and a decline in the net interest margin, driven in part by a decision to increase the securities portfolio and a competitive funding environment. Our fourth quarter expenses were impacted by a $13 million charge related to Visa and $2 million of moving costs related to our previously announced headquarters relocation.

"We opened 30 new banking centers in 2007, 28 of them in our high-growth markets of Texas, California and Arizona. We also relocated our corporate headquarters from Detroit to Dallas, positioning our company in a more central location with greater accessibility to all of our markets. Our capital position remains solid and provides us with a cushion to weather continued challenges in the economic environment and the flexibility to continue to invest in our growth markets."

  Fourth Quarter and Full Year 2007 Highlights

  Fourth Quarter 2007 Compared to Third Quarter 2007

  -- On an annualized basis, excluding Financial Services Division (FSD)
     loans, average loans increased nine percent, led by growth of 28
     percent in the Texas market, eight percent in the Western market, six
     percent in the Florida market and two percent in the Midwest market

  -- The net interest margin was 3.43 percent in the fourth quarter 2007, a
     decrease of 23 basis points from 3.66 percent in the third quarter
     2007, largely due to securities purchases, competitive loan pricing,
     interest reversals on new nonaccrual loans, a competitive deposit
     pricing environment that had a muted reaction to recent Federal Reserve
     rate cuts and an increase in borrowings at higher market-driven costs
     due to disruptions in financial markets

  -- Net credit-related charge-offs were $64 million, or 50 basis points as
     a percent of average total loans, for the fourth quarter 2007, compared
     to $40 million, or 32 basis points as a percent of average total loans,
     for the third quarter 2007

  -- Noninterest income remained flat at $230 million and included positive
     trends in fiduciary income, service charges on deposit accounts and
     commercial lending fees, offset by a decrease in net income from
     principal investing and warrants

  -- Noninterest expenses increased $27 million from the third quarter 2007,
     mostly due to the recording of a $13 million estimated liability
     related to membership in Visa and a $9 million increase in salaries
     expense, primarily due to increases in severance and deferred
     compensation plan costs (offset by an increase in deferred compensation
     asset returns in noninterest income)

  -- Open market share repurchases in the fourth quarter 2007 totaled 1.0
     million shares, or one percent of total shares outstanding at September
     30, 2007


  Full Year 2007 Compared to Full Year 2006

  -- Excluding Financial Services Division loans, average loan growth was
     seven percent, with 16 percent growth in the Texas market, 13 percent
     in the Western market and 11 percent in the Florida market, with the
     Midwest market down one percent

  -- The net interest margin was 3.66 percent

  -- Total revenue increased two percent, including four percent growth in
     noninterest income. Excluding a $47 million Financial Services
     Division-related lawsuit settlement and the $12 million loss on the
     sale of the Mexican bank charter in 2006, total revenue growth was
     three percent, and noninterest income growth was eight percent

  -- Net credit-related charge-offs were 31 basis points as a percent of
     average total loans for 2007, compared to 15 basis points for 2006

  -- Noninterest expenses increased $17 million, or one percent, from 2006.
     2007 included incremental expenses related to new banking centers ($23
     million), the Visa charge discussed above ($13 million) and costs
     associated with the previously announced headquarters move to Dallas,
     Texas ($6 million). 2006 included interest on tax liabilities ($38
     million), which was classified in the "provision for income taxes" in
     2007 (see "Tax-related items" below). Full time equivalent employees
     increased less than one percent from December 31, 2006, to December 31,
     2007, even with the addition of 30 new banking centers during the
     period

  -- Open market share repurchases in 2007 totaled 10.0 million shares, or
     six percent of total shares outstanding at December 31, 2006


  Net Interest Income and Net Interest Margin

  (dollar amounts in millions)       4th Qtr '07   3rd Qtr '07   4th Qtr '06
  Net interest income                   $489          $503          $502

  Net interest margin                   3.43%         3.66%         3.75%

  Selected average balances:
   Total earning assets              $56,621       $54,641       $53,289
   Total loans                        50,699        49,874        48,568
   Total loans, excluding FSD loans
    (primarily low-rate)              49,758        48,683        46,659

   Total interest-bearing deposits    31,834        30,276        30,554
   Total noninterest-bearing
    deposits                          10,533        10,840        12,649
   Total noninterest-bearing
    deposits, excluding FSD            8,473         8,265         8,696

  -- The $14 million decrease in net interest income in the fourth quarter
     2007, when compared to third quarter 2007, resulted primarily from
     competitive loan pricing and a competitive deposit pricing environment
     that had a muted reaction to recent Federal Reserve rate cuts,
     partially offset  by growth in earning assets.

  -- The net interest margin of 3.43 percent declined 23 basis points,
     reflecting securities purchases, competitive loan pricing, a
     competitive deposit pricing environment, interest reversals on new
     nonaccrual loans and an increase in borrowings at higher market-driven
     costs due to disruptions in financial markets. The impact of a decline
     in average Financial Services Division noninterest bearing deposits was
     largely offset by a decline in average Financial Services Division
     loans (primarily low-rate).

  Noninterest Income

Noninterest income was $230 million for the fourth quarter 2007, compared to $230 million for the third quarter 2007 and $262 million for the fourth quarter 2006. Noninterest income in the fourth quarter 2007, compared to the third quarter 2007, included positive trends in fiduciary income, service charges on deposit accounts, commercial lending fees and an increase in deferred compensation asset returns, offset by a decrease in net income from principal investing and warrants. Fourth quarter 2006 noninterest income included $47 million from the settlement of a Financial Services Division- related lawsuit. Certain categories of noninterest income are highlighted in the table below.

  * Compensation deferred by Comerica officers is invested in stocks and
    bonds to reflect the investment selections of the officers. Income
    (loss) earned on these assets is reported in noninterest income and the
    offsetting increase (decrease) in the liability is reported in salaries
    expense.


  Noninterest Expenses

Noninterest expenses were $450 million for the fourth quarter 2007, compared to $423 million for the third quarter 2007 and $457 million for the fourth quarter 2006. The $27 million increase in noninterest expenses in the fourth quarter 2007, compared to the third quarter 2007, reflected $13 million to record an estimated liability related to membership in Visa (discussed below), a $9 million increase in salaries expense and a $3 million increase in the provision for credit losses on lending-related commitments, partially offset by a $4 million decrease in customer services expense. The increase in salaries expense was primarily due to increases in severance and deferred compensation plan costs (offset by an increase in deferred compensation asset returns in noninterest income). Customer services expense varies from period to period as a result of changes in the level of noninterest-bearing deposits in the Corporation's Financial Services Division, the earnings credit allowance provided on these deposits and a competitive environment. In addition, noninterest expenses included approximately $2 million of costs related to the previously announced relocation of Comerica's headquarters to Dallas, Texas, in both the fourth quarter and third quarters of 2007, reflected in salaries and other noninterest expenses.

Members of the Visa card association participate in a loss sharing arrangement to allocate financial responsibilities arising from any potential adverse resolution of certain antitrust lawsuits challenging the practices of the association. Comerica recorded a $13 million expense in the fourth quarter 2007 (in "litigation and operational losses") related to this loss sharing arrangement. Comerica believes that its share of the proceeds from the expected initial public offering of Visa, anticipated in the first quarter 2008, will exceed its share of recorded losses.

Certain categories of noninterest expenses are highlighted in the table below.

  * Effective with the adoption of FASB Interpretation No. 48, "Accounting
    for Uncertainty in Income Taxes - an interpretation of FASB Statement
    No. 109," Comerica changed its accounting policy and prospectively began
    to classify interest on tax liabilities in the "provision for income
    taxes." Prior to January 1, 2007, interest on tax liabilities was
    classified in "other noninterest expenses."

  n/a - not applicable


  Tax-related Items

Interest on tax liabilities was classified in the "provision for income taxes" in 2007 and in "other noninterest expenses" in 2006. Fourth quarter 2007 interest on tax liabilities reflected a $9 million reduction ($6 million after-tax) of interest resulting from a settlement with the Internal Revenue Service on asset depreciation.

Fourth quarter 2006 reflected a charge of $31 million after-tax to Comerica's combined tax and related interest reserves for disallowed loan benefits related to a series of loans to foreign borrowers 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.

Credit Quality

"We increased the provision for loan losses by $63 million from the third quarter, due to the continued residential real estate development challenges in Michigan and California," said Babb.

  -- The allowance to loan ratio increased to 1.10 percent at December 31,
     2007, from 1.03 percent at September 30, 2007

  -- The provision for loan losses and loan quality reflected ongoing
     challenges to the residential real estate development industry located
     in Michigan (Midwest market) and both northern and southern California
     (Western market)

  -- Nonperforming assets increased to 83 basis points of total loans and
     foreclosed property for the fourth quarter 2007. During the fourth
     quarter 2007, $185 million of loan relationships greater than $2
     million were transferred to nonaccrual status, an increase of $91
     million from the third quarter 2007. Of the transfers of loan
     relationships greater than $2 million to nonaccrual in the fourth
     quarter 2007, $143 million were in the real estate industry, $60
     million were from the Midwest market and $103 million were from the
     Western market

  Balance Sheet and Capital Management

Total assets and common shareholders' equity were $62.3 billion and $5.1 billion, respectively, at December 31, 2007, compared to $60.0 billion and $5.1 billion, respectively, at September 30, 2007. There were approximately 150 million shares outstanding at December 31, 2007, compared to 151 million shares outstanding at September 30, 2007. Open market share repurchases for the current and prior quarter and full year 2007 are shown in the following table:

Comerica's fourth quarter 2007 estimated Tier 1 common, Tier 1 and total risk-based capital ratios were 6.80 percent, 7.46 percent and 11.11 percent, respectively.

Full Year 2008 Outlook Compared to Full Year 2007 from Continuing Operations

  -- Mid to high single-digit average loan growth, excluding Financial
     Services Division loans, with flat growth in the Midwest market, high
     single-digit growth in the Western market and low double-digit growth
     in the Texas market

  -- Average earning asset growth in excess of average loan growth

  -- Average Financial Services Division noninterest-bearing deposits of
     $1.2 to $1.4 billion. Financial Services Division loans will fluctuate
     in tandem with the level of noninterest-bearing deposits

  -- Based on a 50 basis point Federal Reserve rate cut in January and a 25
     basis point cut in March 2008, average full year net interest margin
     between 3.20 and 3.25 percent, including the effects of higher levels
     of securities, lower value of noninterest-bearing deposits, absence of
     the benefit  of maturing swaps with negative spreads (10 basis points
     in 2007) and the 2008 FAS 91 impact discussed below

  -- Average net credit-related charge-offs between 40 and 50 basis points
     of average loans, with a provision for credit losses exceeding net
     charge-offs

  -- Low single-digit growth in noninterest income

  -- Low single-digit decline in noninterest expenses, excluding the
     provision for credit losses on lending-related commitments and
     including the 2008 FAS 91 impact discussed below

  -- Effective tax rate of about 32 percent

  -- Maintain a Tier one common capital ratio similar to year-end 2007

  -- Statement of Financial Accounting Standards No. 91 (FAS 91) -
     Accounting for Loan Origination Fees and Costs.  Beginning in 2008, a
     change in the application of FAS 91 will result in deferral and
     amortization (over the loan life) to net interest income of more fees
     and costs.  Based on assumptions for loan growth, loan fees and average
     loan life, the estimated impact on 2008, compared to 2007, will be to
     lower the net interest margin by about 3-4 basis points (approximately
     $20 million), lower noninterest expenses by about 3-4 percent
     (approximately $60 million) and increase earnings per share by about
     four cents per quarter

     decline in the Financial Services Division, primarily due to growth in
     Technology and Life Sciences, Global Corporate and Middle Market,
     partially offset by a decrease in Commercial Real Estate

  -- The net interest margin of 3.22 percent decreased nine basis points,
     primarily due to narrowing loan and deposit spreads resulting from
     competitive loan and deposit pricing

  -- The provision for loan losses increased $45 million, primarily due to
     declining credit quality in Commercial Real Estate (residential real
     estate developers) and increased reserves in Technology and Life
     Sciences primarily related to a single customer, partially offset by a
     decline in reserves related to the automotive supplier portfolio, which
     continued to reduce in size and exhibited stable credit quality metrics

  -- Noninterest expenses increased $9 million, primarily due to an increase
     in net corporate overhead expenses resulting from year end adjustments
     to allocation rates

  Geographic Market Segments

Comerica also provides market segment results for four primary geographic markets: Midwest, Western, Texas and Florida. In addition to the four primary geographic markets, Other Markets and International are also reported as market segments. In the fourth quarter 2007, Comerica revised the definition of Other Markets to include businesses with a national perspective, which were previously included primarily in the Midwest market. The financial results below are based on methodologies in effect at December 31, 2007 and are presented on a fully taxable equivalent (FTE) basis. The accompanying narrative addresses fourth quarter 2007 results compared to third quarter 2007.

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

  -- Average loans increased $76 million, or two percent on an annualized

  -- Average deposits increased $481 million, primarily in the Global
     Corporate and Small Business Banking lines of business

  -- The net interest margin of 4.38 percent declined 22 basis points,
     primarily due to a decline in loan and deposit spreads resulting from
     competitive loan and deposit pricing

  -- The provision for loan losses increased $5 million, primarily due to an
     increase in credit risk in the Commercial Real Estate line of business
     (residential real estate developers) and a modest increase in charge-

     in reserves related to the automotive supplier portfolio, which
     continued to reduce in size and exhibited stable credit quality metrics

  -- Noninterest expenses increased $12 million, partially due to the Visa-
     related expense as discussed above, the provision for credit losses on

     growth in the Middle Market Banking, Technology and Life Sciences and

     $565 million, primarily due to growth in the Middle Market Banking,
     Private Banking, Retail Banking, Technology and Life Sciences and

  -- The net interest margin of 4.13 percent declined 11 basis points due to
     a decline in deposits spreads resulting from competitive pricing

  -- The provision for loan losses increased $69 million, primarily due to a

     Sciences primarily related to a single customer

  -- Noninterest expenses increased $11 million, primarily due to banking
     center expansion, the Visa-related expense discussed above, advertising

     service expenses

Words such as "anticipates," "believes," "feels," "expects," "estimates," "seeks," "strives," "plans," "intends," "outlook," "forecast," "position," "target," "mission," "assume," "achievable," "potential," "strategy," "goal," "aspiration," "outcome," "continue," "remain," "maintain," "trend," "objective" and variations of such words and similar expressions, or future or conditional verbs such as "will," "would," "should," "could," "might," "can," "may" or similar expressions, as they relate to Comerica or its management, are intended to identify forward-looking statements. These forward-looking statements are predicated on the beliefs and assumptions of Comerica's management based on information known to Comerica's management as of the date of this news release and do not purport to speak as of any other date. Forward-looking statements may include descriptions of plans and objectives of Comerica's management for future or past operations, products or services, and forecasts of Comerica's revenue, earnings or other measures of economic performance, including statements of profitability, business segments and subsidiaries, estimates of credit trends and global stability. Such statements reflect the view of Comerica's management as of this date with respect to future events and are subject to risks and uncertainties. Should one or more of these risks materialize or should underlying beliefs or assumptions prove incorrect, Comerica's actual results could differ materially from those discussed. Factors that could cause or contribute to such differences are changes in the pace of an economic recovery and related changes in employment levels, changes related to the headquarters relocation or to its underlying assumptions, the effects of war and other armed conflicts or acts of terrorism, the effects of natural disasters including, but not limited to, hurricanes, tornadoes, earthquakes and floods, the disruption of private or public utilities, the implementation of Comerica's strategies and business models, management's ability to maintain and expand customer relationships, changes in customer borrowing, repayment, investment and deposit practices, management's ability to retain key officers and employees, changes in the accounting treatment of any particular item, the impact of regulatory examinations, declines or other changes in the businesses or industries in which Comerica has a concentration of loans, including, but not limited to, the automotive production industry and the real estate business lines, the anticipated performance of any new banking centers, the entry of new competitors in Comerica's markets, changes in the level of fee income, changes in applicable laws and regulations, including those concerning taxes, banking, securities and insurance, changes in trade, monetary and fiscal policies, including the interest rate policies of the Board of Governors of the Federal Reserve System, fluctuations in inflation or interest rates, changes in general economic, political or industry conditions and related credit and market conditions, and adverse conditions in the stock market. Comerica cautions that the foregoing list of factors is not exclusive. Forward-looking statements speak only as of the date they are made. Comerica does not undertake to update forward-looking statements to reflect facts, circumstances, assumptions or events that occur after the date the forward- looking statements are made. For any forward-looking statements made in this news release or in any documents, Comerica claims the protection of the safe harbor for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995.
