* 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.

“Despite the challenged economic environment, we remained focused on executing our strategy in the first quarter, as evidenced by good loan and deposit growth, particularly in our high-growth markets,” said Ralph W. Babb Jr., chairman and chief executive officer. “While the continued deterioration of the California residential real estate market and its effects on our residential real estate development portfolio affected our overall performance, the remainder of our loan portfolio continued to exhibit stable credit metrics.

“As expected, the net interest margin of 3.22 percent declined 21 basis points from the fourth quarter, largely due to planned securities purchases, expected loan growth in excess of core deposit growth, and the reduced contribution of noninterest-bearing funds in a lower rate environment.

“Our expenses were well controlled in the first quarter with reduced headcount, even as we continued our banking center expansion program.”

First Quarter 2008 Compared to Fourth Quarter 2007

• On an annualized basis, excluding Financial Services Division (FSD) loans, average loans increased 10 percent, with growth of 14 percent in the Texas market, 10 percent in the Western market and 9 percent in the Midwest market.

• On an annualized basis, total deposits, excluding FSD deposits and institutional certificates of deposit, increased five percent, including an increase in noninterest-bearing deposits of 12 percent. Deposit growth occurred while deposit rates were lowered. Funding sources also included $2 billion of new advances from the Federal Home Loan Bank of Dallas with a five-year term at an attractive rate.

• The net interest margin was 3.22 percent in the first quarter 2008, a decrease of 21 basis points from 3.43 percent in the fourth quarter 2007, largely due to planned securities purchases, expected loan growth in excess of core deposit growth and the reduced contribution of noninterest-bearing funds in a lower rate environment.

• Net credit-related charge-offs were $110 million, or 85 basis points as a percent of average total loans, for the first quarter 2008, compared to $64 million, or 50 basis points as a percent of average total loans, for the fourth quarter 2007. Of the first quarter charge-offs, $75 million were in the Commercial Real Estate business line, predominantly with residential real estate developers in the Western market. The remaining net charge-offs of $35 million were 31 basis points of average non-Commercial Real Estate loans. The provision for loan losses was $159 million for the first quarter 2008, compared to $108 million for the fourth quarter 2007, bringing the period-end allowance to total loans ratio to 1.16 percent from 1.10 percent at December 31, 2007.

• Noninterest income increased $7 million, and included a $21 million gain on Visa shares, with increases in investment banking fees and service charges on deposit accounts, partially offset by decreases in net income from principal investing and warrants, seasonally lower commercial lending fees, and deferred compensation asset returns (which are offset by a decrease in deferred compensation plan costs in noninterest expenses).

• Noninterest expenses decreased $47 million from the fourth quarter 2007, mostly due to the first quarter 2008 reversal of the $13 million loss sharing arrangement expense that was recorded in the fourth quarter 2007 related to membership in Visa and a $16 million decrease in salaries expense, including a decrease in deferred compensation plan costs in first quarter 2008, partially offset by an increase in share-based compensation expense.

• The estimated Tier 1 common capital ratio was 6.71 percent, within the targeted range.

• The $13 million decrease in net interest income in the first quarter 2008, when compared to fourth quarter 2007, resulted primarily from a reduction in the net interest margin and the impact of one less day ($5 million), partially offset by growth in securities and loans.

• The net interest margin of 3.22 percent declined 21 basis points, when compared to fourth quarter 2007, reflecting the decreased contribution of noninterest-bearing funds in a lower rate environment and earning asset growth in excess of deposit growth, partially offset by deposit rate reductions.

• Securities purchases consisted of AAA-rated mortgage-backed securities issued by government sponsored enterprises (FNMA, FHLMC).

Noninterest Income

Noninterest income was $237 million for the first quarter 2008, compared to $230 million for the fourth quarter 2007 and $203 million for the first quarter 2007. Noninterest income in the first quarter 2008, compared to the fourth quarter 2007, included the $21 million gain on the sale of Visa shares (included in “net securities gains”) and increased service charges on deposit accounts ($1 million) and investment banking fees ($4 million), partially offset by decreases in seasonally lower commercial lending fees ($6 million), net income (loss) from principal investing and warrants ($10 million) and deferred compensation asset returns ($7 million, offset by a decrease in deferred compensation plan costs in noninterest expenses).

Noninterest Expenses

Noninterest expenses were $403 million for the first quarter 2008, compared to $450 million for the fourth quarter 2007 and $407 million for the first quarter 2007. The $47 million decrease in noninterest expenses in the first quarter 2008, compared to the fourth quarter 2007, reflected a $16 million decrease in salaries expense and the reversal of the $13 million Visa loss sharing arrangement expense that was recorded in the fourth quarter 2007 (included in “litigation and operational losses”). The decrease in salaries expense was primarily due to additional cost deferrals from a refinement in application of Statement of Financial Accounting Standards No. 91 — Accounting for Loan Origination Fees and Costs (FAS 91) ($11 million), a decrease in deferred compensation plan costs ($7 million) and reduced headcount, partially offset by an increase of $8 million in share-based compensation, reflecting that portion of the annual award of restricted stock which must be expensed in the period granted. Certain categories of noninterest expenses are highlighted in the table below.

Tax-related Items

The provision for income taxes reflected a benefit of $5 million resulting from an after-tax adjustment to deferred tax assets in the first quarter 2008. Fourth quarter 2007 interest on tax liabilities (classified in the “provision for income taxes”) reflected a $9 million reduction ($6 million after-tax) of interest resulting from a settlement with the Internal Revenue Service on asset depreciation.

Credit Quality

“California residential real estate developers, in particular, continued to struggle,” said Babb. “The excess inventory, declining prices and extended time to sell have had a debilitating effect on the California housing market. We are aggressively addressing this situation as the market has continued to deteriorate.”

• The allowance to loan ratio increased to 1.16 percent at March 31, 2008, from 1.10 percent at December 31, 2007.

• The provision for loan losses and loan quality reflected increased challenges primarily in residential real estate development located in both northern and southern California (Western market).

• Net loan charge-offs in the Commercial Real Estate business line in the first quarter 2008 were $75 million, of which $58 million were from residential real estate developers in the Western market. Comparable numbers for the fourth quarter 2007 were $36 million in total, of which $9 million were from residential real estate developers in the Western market. Excluding the Western market, other Commercial Real Estate net loan charge-offs in the first quarter 2008 totaled $17 million, compared to $27 million in the fourth quarter 2007. In California, the median sales price of existing single family homes declined almost 14 percent from the fourth quarter 2007 (30 percent from one year ago) and single family home building permits (trailing 12 months) declined over 10 percent (33 percent from one year ago).

• Net loan charge-offs, excluding the Commercial Real Estate business line, were $35 million in the first quarter 2008, or 31 basis points of average non-Commercial Real Estate loans, compared to $27 million in the fourth quarter 2007, or 25 basis points of average non-Commercial Real Estate loans.

Balance Sheet and Capital Management

Total assets and common shareholders’ equity were $67.0 billion and $5.3 billion, respectively, at March 31, 2008, compared to $62.3 billion and $5.1 billion, respectively, at December 31, 2007. There were approximately 151 million shares outstanding at March 31, 2008, compared to 150 million shares outstanding at December 31, 2007. No shares were repurchased in the open market in the first quarter 2008.

Comerica’s first quarter 2008 estimated Tier 1 common, Tier 1 and total risk-based capital ratios were 6.71 percent, 7.35 percent and 11.00 percent, respectively.

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

• Mid single-digit average loan growth, excluding Financial Services Division loans, with low single-digit growth in the Midwest market, mid to 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, with securities averaging about $8 billion for the remainder of the year.

• Average Financial Services Division noninterest-bearing deposits of $1.7 to $1.9 billion. Financial Services Division loans will fluctuate in tandem with the level of noninterest-bearing deposits.

• Based on the federal funds rate declining to 1.75 percent by mid-year 2008, average full year net interest margin around 3.10 percent, including the effects of higher levels of securities, lower value of noninterest-bearing deposits and average loan growth exceeding average deposit growth.

• Average net credit-related charge-offs of 75-80 basis points of average loans. The provision for credit losses is expected to exceed net charge-offs.

• Low single-digit growth in noninterest income.

• Low single-digit decline in noninterest expenses.

• Effective tax rate of about 28 percent.

• Maintain a Tier 1 common capital ratio within a target range of 6.50 to 7.50 percent.

• Noninterest expenses decreased $9 million, primarily due to the first quarter 2008 reversal of the $2 million Visa loss sharing arrangement expense recorded in the fourth quarter 2007 and a decrease in salaries expense related to the refinement in application of FAS 91.
