COMERICA REPORTS THIRD QUARTER 2008 EARNINGS

Core Operating Earnings Stable

Provision for Credit Losses, Net Charge-Offs Unchanged

Loan Optimization Program Producing Desired Results

DALLAS/October 17, 2008 — Comerica Incorporated (NYSE: CMA) today reported third quarter 2008 income from continuing operations of $27 million, or $0.18 per diluted share, compared to $56 million, or $0.37 per diluted share, for the second quarter 2008 and $180 million, or $1.17 per diluted share, for the third quarter 2007. Third quarter 2008 included a $174 million provision for credit losses, compared to $177 million for the second quarter 2008 and $45 million for the third quarter 2007. During the third quarter 2008, Comerica recognized a pre-tax charge of $96 million ($61 million after-tax, or $0.40 per diluted share), recorded in “litigation and operational losses,” related to a previously announced offer to repurchase (at par) auction-rate securities (ARS) from customers. In addition, third quarter 2008 net income reflected a $27 million pre-tax gain ($17 million after-tax, or $0.11 per diluted share) related to the sale of shares in Visa, Inc. (Visa) and net after-tax charges of $7 million ($0.04 per diluted share) which included settlements with the Internal Revenue Service on disallowed foreign tax credits related to a series of loans to foreign borrowers and both the net interest income impact and tax-related interest on certain structured leasing transactions, as well as other adjustments to tax reserves.

COMERICA REPORTS THIRD QUARTER 2008 EARNINGS — 2

“In an economic environment that is as challenging and volatile as any we have ever seen, Comerica’s core operating earnings remained stable compared to the prior two quarters,” said Ralph W. Babb Jr., chairman and chief executive officer. “As expected, net credit-related charge-offs and the provision for loan losses were unchanged.

“In this uncertain environment, we are taking actions to improve our capital ratios and enhance our balance sheet strength, including a previously announced intention to reduce our dividend and the execution of a loan optimization program, which is working and producing the desired results. Maintaining a solid capital position is prudent and provides us the flexibility to navigate these swift economic currents and continue to invest in our growth markets.”

Third Quarter 2008 Compared to Second Quarter 2008

•

In response to Comerica’s loan optimization plan, average loans declined seven percent on an annualized basis, with declines of five percent in the Texas market, three percent in the Midwest market and 13 percent in the Western market.

•

On an annualized basis, average noninterest-bearing deposits, excluding Financial Services Division (FSD) deposits, increased 13 percent.

•

September 30, 2008, core deposits, excluding the Financial Services Division, increased $273 million compared to June 30, 2008, due to increases in noninterest-bearing deposits and customer certificates of deposit.

•

The net interest margin was 3.11 percent in the third quarter 2008, or 3.17 percent excluding the charge to interest income on certain structured lease transactions.

•

Net credit-related charge-offs were $116 million, or 90 basis points as a percent of average total loans, for the third quarter 2008, compared to $113 million, or 86 basis points as a percent of average total loans, for the second quarter 2008. The provision for loan losses was $165 million for the third quarter 2008, compared to $170 million for the second quarter 2008, and the period-end allowance to total loans ratio increased to 1.38 percent from 1.28 percent at June 30, 2008.

•

Excluding net securities gains, noninterest income decreased $15 million, primarily the result of a $10 million decrease in deferred compensation asset returns (which is offset by a decrease in deferred compensation plan costs in noninterest expenses).

•

Noninterest expenses increased $91 million from the second quarter, due to the $96 million charge related to the offer to repurchase ARS, partially offset by a decrease in deferred compensation plan costs ($10 million).

•

The estimated Tier 1 common and Tier 1 capital ratios were 6.69 and 7.35 percent, respectively, both within the targeted ranges. The $96 million ($61 million, after-tax) ARS charge and related commitment to repurchase reduced the estimated Tier 1 common and Tier 1 capital ratios by 21 basis points and 22 basis points, respectively.

Total noninterest-bearing deposits, excluding FSD		9,104			8,825			8,265


*		Third quarter 2008 and second quarter 2008 net interest income declined $8 million and $30 million, respectively, and the net interest margin declined six basis points and 19 basis points, respectively, due to tax-related non-cash lease income charges. Excluding these charges, the net interest margin would have been 3.17 percent in the third quarter 2008 and 3.10 percent in the second quarter 2008.

**		Core deposits exclude institutional certificates of deposit and foreign office time deposits.

•

The $24 million increase in net interest income in the third quarter 2008, when compared to second quarter 2008, resulted primarily from the second quarter $30 million non-cash charge to lease income, partially offset by the third quarter $8 million non-cash charge to lease income.

•

The net interest margin of 3.11 percent increased seven basis points, after excluding the tax-related non-cash lease income charges of 19 basis points in the second quarter 2008 and six basis points in the third quarter 2008, due to improved loan spreads and lower deposit rates.

•

Total average Financial Services Division deposits decreased $368 million from the second quarter 2008 and $1.3 billion from the third quarter 2007. This division serves title and escrow companies that facilitate residential mortgage transactions and benefits from customer deposits related to mortgage escrow balances. Deposits declined due to cooling of the California housing market, combined with destabilization of the mortgage market.

Noninterest Income

Noninterest income was $240 million for the third quarter 2008, compared to $242 million for the second quarter 2008 and $230 million for the third quarter 2007. Net securities gains in noninterest income included a $27 million gain on the sale of Comerica’s remaining ownership of Visa shares in the third quarter 2008 and a $14 million gain on the sale of MasterCard shares in the second quarter 2008. In addition, deferred compensation asset returns decreased $10 million in the third quarter 2008, when compared to the second quarter 2008 (which is offset by a decrease in deferred compensation plan costs in noninterest expenses). Certain categories of noninterest income are highlighted in the table below.

Noninterest Expenses

Noninterest expenses were $514 million for the third quarter 2008, compared to $423 million for both the second quarter 2008 and third quarter 2007. The $91 million increase in noninterest expenses in the third quarter 2008, compared to the second quarter 2008, reflected the $96 million charge related to the offer to repurchase ARS (included in “litigation and operational losses”), partially offset by a decrease in deferred compensation plan costs ($10 million). The ARS repurchases from customers will be completed in the fourth quarter 2008. Certain categories of noninterest expenses are highlighted in the table below.

*		Third quarter 2008 litigation and operational losses included a $96 million charge related to an offer to repurchase auction-rate securities from customers.

Tax-related Items

The third quarter 2008 provision for income taxes reflected net after-tax charges of $1 million which included the acceptance of a global settlement offered by the Internal Revenue Service (IRS) on certain structured leasing transactions, settlement with the IRS on disallowed foreign tax credits related to a series of loans to foreign borrowers and other adjustments to tax reserves. The second quarter 2008 provision for income taxes reflected an after-tax charge of $13 million related to the structured leasing transactions. The reassessment of the size and timing of tax deductions related to the leasing transactions also resulted in the $8 million ($6 million after-tax) and $30 million ($19 million after-tax) respective charges to lease income in the third and second quarters of 2008 previously discussed.

Credit Quality

“Net charge-offs related to Western market residential real estate development were lower than the two previous quarters, reflecting our aggressive management of this portfolio,” said Babb. “As expected, we are seeing softness in small business and middle market, which is consistent with our outlook.”

•

The allowance to loan ratio increased to 1.38 percent at September 30, 2008, from 1.28 percent at June 30, 2008.

•

The provision for loan losses and loan quality reflected continuing challenges in residential real estate development located in the Western market (primarily California) and the economies in all major markets.

•

Net credit-related charge-offs in the Commercial Real Estate business line in the third quarter 2008 were $57 million, of which $39 million were from residential real estate developers in the Western market. Comparable numbers for the second quarter 2008 were $73 million in total, of which $56 million were from residential real estate developers in the Western market.

•

Net loan charge-offs, excluding the Commercial Real Estate business line, were $59 million in the third quarter 2008, or 52 basis points of average non-Commercial Real Estate loans, compared to $40 million, or 35 basis points, in the second quarter 2008.

•

Nonperforming assets increased to 1.71 percent of total loans and foreclosed property for the third quarter 2008. During the third quarter 2008, $280 million of loan relationships greater than $2 million were transferred to nonaccrual status, a decrease of $24 million from the second quarter 2008. Of the transfers of loan relationships greater than $2 million to nonaccrual in the third quarter 2008, $145 million were in the Commercial Real Estate business line, a decrease of $43 million from the second quarter 2008.

Balance Sheet and Capital Management

Total assets and common shareholders’ equity were $65.2 billion and $5.1 billion, respectively, at September 30, 2008, compared to $66.0 billion and $5.1 billion, respectively, at June 30, 2008. There were approximately 150 million shares outstanding at September 30, 2008. No shares were repurchased in the open market in the first nine months of 2008.

Comerica’s third quarter 2008 estimated Tier 1 common, Tier 1 and total risk-based capital ratios were 6.69 percent, 7.35 percent and 11.22 percent, respectively. The $96 million ($61 million, after-tax) ARS charge and related commitment to repurchase reduced the estimated Tier 1 common, Tier 1 and total capital ratios by 21 basis points, 22 basis points and 29 basis points, respectively.

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

•

Low to mid single-digit full-year average loan growth, with loans declining in the fourth quarter 2008.

•

Mortgage-backed FNMA and FHLMC securities (AAA-rated) averaging about $8 billion for the fourth quarter 2008. In addition, about $1.4 billion of ARS will be repurchased during the fourth quarter 2008.

•

Average full-year net interest margin about 3.05 percent (3.10 percent excluding the second and third quarter lease income charges), with a net interest margin of about 3.00 percent in the fourth quarter 2008. The fourth quarter net interest margin reflects the three basis point negative impact of ARS repurchases and the 50 basis point reduction in the federal funds rate announced October 8, 2008. This full-year net interest margin reflects a five basis point decline from the previous outlook.

•

Full-year net credit-related charge-offs of about $450 million. The provision for credit losses is expected to exceed net charge-offs.

•

Mid single-digit growth in noninterest income.

•

Low single-digit increase in noninterest expenses (low single-digit decrease excluding the charge related to the offer to repurchase ARS).

•

Effective tax rate of about 27 percent for the full year, with a rate of about 20 percent for the fourth quarter 2008.

•

Maintain a Tier 1 capital ratio within a target range of 7.25 to 8.25 percent.

*		September 30, 2008 ratios are estimated

**		Third quarter 2008 and second quarter 2008 net interest income declined $8 million and $30 million, respectively, due to tax-related non-cash lease income charges. Excluding these charges, the net interest margin would have been 3.17% and 3.10% for the three-month periods ended September 30, 2008, and June 30, 2008, respectively, and 3.16% for the nine-month period ended September 30, 2008.
