* 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

• 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.

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.”

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.

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 billion 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

• 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

• 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 decline in credit quality in Commercial Real Estate (residential real estate developers), a modestly higher level of charge-offs related to Small Business Banking and increased reserves in Technology and Life 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 expenses and net corporate overhead expenses, for the same reason noted in the Business Bank, partially offset by a decrease in customer service expenses

• Eleven new banking centers were opened in the fourth quarter, eight in California and three in Arizona. In 2007, a total of 13 new banking centers were opened in California and three in Arizona
