"We were pleased by the continued growth in average total loans in the first quarter, driven by a $1.2 billion, or 5 percent, increase in average commercial loans," said Ralph W. Babb Jr., chairman and chief executive officer. "The increase in average commercial loans, when compared to the fourth quarter of 2011, was broad-based, across a majority of business lines and all major markets.

"Noninterest income increased $24 million, driven by a $10 million, or 6 percent, increase in customer-driven fees, offsetting the headwinds of regulatory reform.

"We continue to approach capital management from a position of strength," said Babb. "As we announced on March 14, 2012, the Federal Reserve did not object to our capital plan and the capital distributions contemplated in the plan. The capital plan, which was approved by our board of directors, provides for up to $375 million in equity repurchases from the first quarter 2012 through the first quarter 2013. We had $33 million in equity repurchases under the share repurchase program in the first quarter 2012. A dividend proposal that would increase the quarterly dividend 50 percent, from 10 cents per share to 15 cents per share, will be considered by our board at its next meeting on April 24, 2012."

First Quarter 2012 Highlights Compared to Fourth Quarter 2011

    --  Net income of $130 million, or $0.66 per fully diluted share, increased
        36 percent compared to fourth quarter 2011.
    --  Average total loans increased $815 million, or 2 percent, primarily
        reflecting an increase of $1.2 billion, or 5 percent, in commercial
        loans, partially offset by a decrease of $352 million, or 3 percent, in
        commercial real estate loans (commercial mortgage and real estate
        construction loans). The increase in commercial loans was broad-based,
        primarily driven by increases in National Dealer Services, Energy,
        Global Corporate Banking, Middle Market Banking, and Technology and Life
        Sciences.
    --  Period-end loans increased $333 million, or 1 percent, from December 31,
        2011 to March 31, 2012, primarily reflecting an increase of $644
        million, or 3 percent, in commercial loans, partially offset by a $276
        million, or 2 percent, decrease in commercial real estate loans. The
        increase in period-end commercial loans was primarily driven by
        increases in National Dealer Services, Middle Market Banking, Global
        Corporate Banking and Energy, partially offset by decreases in Mortgage
        Banker Finance and Small Business Banking.
    --  Average deposits increased $532 million, or 1 percent, primarily
        reflecting an increase of $461 million in noninterest-bearing deposits.
        Period end deposits increased $1.5 billion from December 31, 2011 to a
        record $49.3 billion at March 31, 2012, while funding costs continued to
        decline. The increase in average deposits primarily reflected increases
        in Global Corporate Banking, the Financial Services Division, Technology
        and Life Sciences, and Private Banking, partially offset by decreases in
        Small Business Banking and Energy.
    --  Credit quality continued to improve in the first quarter 2012. Net
        credit-related charge-offs of $45 million decreased for the eleventh
        consecutive quarter. The provision for loan losses was $23 million in
        the first quarter 2012, compared to $19 million in the fourth quarter
        2011.
    --  Noninterest income increased to $206 million in the first quarter 2012,
        compared to $182 million for the fourth quarter 2011. The $24 million
        increase in large part resulted from increases in customer-driven fee
        income categories.
    --  Noninterest expenses decreased $30 million to $448 million in the first
        quarter 2012, compared to the fourth quarter 2011. The decrease was
        primarily due to a $37 million decrease in merger and restructuring
        charges related to the Sterling acquisition.
    --  As previously announced, the Federal Reserve completed its review of
        Comerica's 2012 Capital Plan in the first quarter 2012 and did not
        object to the capital distributions contemplated in the plan, including
        up to $375 million of equity repurchases in the five-quarter period
        ending March 31, 2013 and a 50 percent increase in the quarterly
        dividend. Comerica repurchased 1.1 million shares of common stock under
        the share repurchase program in the first quarter 2012.

    -----------------      ------                      ------                      ------
    --  Net interest income of $443 million in the first quarter 2012 decreased
        $1 million compared to the fourth quarter 2011, as the benefit from a
        $510 million increase in average earning assets ($7 million) and lower
        funding costs ($2 million) was offset by lower loan yields ($5 million)
        and one less day in the quarter ($5 million). The lower loan yields
        reflected a shift in the average loan portfolio mix, largely due to the
        decrease in average commercial real estate loans and the increase in
        average commercial loans. Accretion of the purchase discount on the
        acquired Sterling loan portfolio was $25 million in the first quarter
        2012, compared to $26 million in the fourth quarter 2011. For the
        remainder of 2012, $35 million to $45 million of accretion is expected
        to be recognized.
    --  Average earning assets increased $510 million in the first quarter 2012
        compared to the fourth quarter 2011, primarily reflecting increases of
        $815 million in average loans and $108 million in average investment
        securities available-for-sale, partially offset by a $417 million
        decrease in average Federal Reserve Bank deposits.
    --  Average deposits increased $532 million in the first quarter 2012,
        compared to the fourth quarter 2011, primarily due to a $461 million
        increase in average noninterest-bearing deposits.

Noninterest Income

Noninterest income was $206 million for the first quarter 2012, compared to $182 million for the fourth quarter 2011. The $24 million increase primarily resulted from a $10 million, or 6 percent, increase in customer-driven fee income and a $9 million increase in net securities gains. The increase in customer-driven fee income included increases in service charges on deposit accounts ($4 million), investment banking fees ($3 million), fiduciary income ($2 million) and commercial lending fees ($2 million). The increase in net securities gains reflected an increase of $4 million in gains from redemptions of auction-rate securities in the first quarter 2012, when compared to fourth quarter 2011, and $5 million in charges in the fourth quarter 2011 related to a derivative contract tied to the conversion rate of Visa Class B shares.

Noninterest Expenses

Noninterest expenses totaled $448 million in the first quarter 2012, a decrease of $30 million compared to $478 million in the fourth quarter 2011. The decrease in noninterest expenses was primarily due to decreases in merger and restructuring charges ($37 million), net occupancy expense ($6 million), and salaries expense ($4 million), partially offset by increases in employee benefits expense ($8 million), primarily due to an increase in pension expense, and litigation and legal expenses ($5 million), included in other noninterest expenses. The decrease in net occupancy expense in part reflected savings related to increased efficiency in space utilization. Restructuring charges of approximately $40 million are expected to be incurred for the remainder of 2012, with $5 million to $10 million expected in second quarter 2012.

    (a)             Excludes loans acquired with credit

    (b)             Included in "Accrued expenses and
                    other liabilities" on the
                    consolidated balance sheets.
    (c)             Reflects the impact of acquired
                    loans, which were initially
                    recorded at fair value, with no
                    related allowance for loan losses.

"Credit quality continued to improve in the first quarter," said Babb. "Net charge-offs, which decreased $15 million to $45 million in the first quarter, are at the lowest level since the third quarter of 2007. The provision for loan losses was relatively stable. Our expectation is that we will continue to see the provision and net-charge offs at these levels for the remainder of the year assuming the current level of economic growth is sustained."

    --  Net credit-related charge-offs decreased $15 million to $45 million in
        the first quarter 2012, from $60 million in the fourth quarter 2011. The
        decrease in net credit-related charge-offs was broad-based, spread
        across many business lines.
    --  The provision for loan losses was $23 million in the first quarter 2012,
        compared to $19 million in the fourth quarter 2011. The change in the
        provision for loan losses reflects increased loan volumes.
    --  Internal watch list loans continued the downward trend, declining $261
        million in the first quarter 2012, to $4.2 billion at March 31, 2012.
        Nonperforming assets decreased $58 million to $923 million at March 31,
        2012.
    --  During the first quarter 2012, $69 million of borrower relationships
        over $2 million were transferred to nonaccrual status, a decrease of $30
        million from the fourth quarter 2011.
    --  The allowance for loan losses to total loans ratio was 1.64 percent and
        1.70 percent at March 31, 2012 and December 31, 2011, respectively.

Balance Sheet and Capital Management

Total assets and common shareholders' equity were $62.6 billion and $7.0 billion, respectively, at March 31, 2012, compared to $61.0 billion and $6.9 billion, respectively, at December 31, 2011. There were approximately 197 million common shares outstanding at March 31, 2012. Comerica repurchased $33 million of common stock (1.1 million shares) under the share repurchase program during the first quarter 2012.

The Federal Reserve completed its review of Comerica's 2012 Capital Plan in March 2012 and did not object to the capital distributions contemplated in the plan. The capital plan provides for up to $375 million in equity repurchases for the five-quarter period ending March 31, 2013. The capital plan, which was approved by Comerica's Board of Directors, further contemplates a 50 percent increase in Comerica's quarterly dividend, from 10 cents per share to 15 cents per share. The dividend proposal will be considered by the Board at its April 24, 2012 meeting. In addition, the capital plan includes the authority to redeem the remaining $25 million of trust preferred securities outstanding as of March 31, 2012.

Comerica's tangible common equity ratio was 10.21% at March 31, 2012, a decrease of 6 basis points from December 31, 2011. The estimated Tier 1 common capital ratio decreased 4 basis points, to 10.33% at March 31, 2012, from December 31, 2011.

Full-Year 2012 Outlook Compared to Full-Year 2011

For 2012, management expects the following, assuming a continuation of the current economic environment:

    --  Average loans increasing moderately.
    --  Net interest income increasing moderately.
    --  Net credit-related charge-offs and provision for credit losses
        declining.
    --  Noninterest income relatively stable.
    --  Noninterest expenses relatively stable.
    --  Effective tax rate of approximately 27 percent.

In addition to Texas, Comerica Bank locations can be found in Arizona, California, Florida and Michigan, with select businesses operating in several other states, as well as in Canada and Mexico.

This press release contains both financial measures based on accounting principles generally accepted in the United States (GAAP) and non-GAAP based financial measures, which are used where management believes it to be helpful in understanding Comerica's results of operations or financial position. Where non-GAAP financial measures are used, the comparable GAAP financial measure, as well as a reconciliation to the comparable GAAP financial measure, can be found in this press release. These disclosures should not be viewed as a substitute for operating results determined in accordance with GAAP, nor are they necessarily comparable to non-GAAP performance measures that may be presented by other companies.

    (a)            Tier 1 capital and risk-
                    weighted assets as defined
                    by regulation.
    (b)            March 31, 2012 Tier 1
                    capital and risk-weighted
                    assets are estimated.

    The Tier 1 common capital ratio
     removes preferred stock and
     qualifying trust preferred
     securities from Tier 1 capital as
     defined by and calculated in
     conformity with bank regulations.
     The tangible common equity removes
     preferred stock and the effect of
     intangible assets from capital and
     the effect of intangible assets
     from total assets and tangible
     common equity per share of common
     stock removes the effect of
     intangible assets from common
     shareholders equity per share of
     common stock. Comerica believes
     these measurements are meaningful
     measures of capital adequacy used
     by investors, regulators,
     management and others to evaluate
     the adequacy of common equity and
     to compare against other companies
     in the industry.
