"We had an eight percent increase in net income in the first quarter of 2011, when compared to the fourth quarter of 2010, which was primarily driven by reduced credit costs and good control of expenses," said Ralph W. Babb Jr., chairman and chief executive officer. "Among the many positive and encouraging signs we saw in the first quarter were loan growth in the Global Corporate Banking, Energy and Middle Market lines of business, and an acceleration of loan growth in Texas. These were more than offset by the continued and planned reductions in Commercial Real Estate, and a decrease in Mortgage Banker Finance. First quarter revenue was down three percent from the fourth quarter, primarily driven by lower total average loans.

"Key credit metrics continued to move in the right direction in the first quarter. In addition, deposit growth remained strong and our solid capital continued to position us well for future growth. We believe we are in the right markets with the right people and products to build upon this momentum going forward.

"We continue to be on track to close our pending acquisition of Sterling Bancshares in the second quarter, subject to customary closing conditions, including regulatory and Sterling shareholder approvals. Preparations for the integration of Sterling are moving forward, as planned. We expect to complete the systems conversions in the fourth quarter, and anticipate a smooth and seamless transition. Sterling also reported first quarter 2011 earnings today, and they were consistent with our expectations. The more work we do and the better we get to know Sterling, the more confident we are in the fit of our two organizations."

First Quarter 2011 Highlights Compared to Fourth Quarter 2010

    --  Net income of $103 million, or $0.57 per fully diluted share, increased
        eight percent compared to the fourth quarter 2010.
    --  Average loans increased in the Global Corporate Banking business line
        ($276 million; six percent), in Energy Lending in the Specialty
        Businesses business line ($154 million; 12 percent) and in the Middle
        Market business line ($94 million; one percent).  These increases were
        more than offset by decreases in Mortgage Banker Finance in the
        Specialty Businesses business line ($535 million; 49 percent) and in the
        Commercial Real Estate business line ($324 million; seven percent),
        resulting in a decrease in average total loans of $448 million, or one
        percent.
    --  Average loans in the Texas market increased $389 million, or six
        percent, with increases in all major business lines other than
        Commercial Real Estate.
    --  Average core deposits increased $290 million in the first quarter 2011.
    --  The net interest margin of 3.25 percent decreased four basis points,
        primarily resulting from an increase in excess liquidity, represented by
        average balances deposited with the Federal Reserve Bank, and the
        maturity of interest rate swaps at positive spreads.
    --  Average earning assets increased $245 million in the first quarter 2011.
    --  Credit quality improvement continued in the first quarter 2011.  Net
        credit-related charge-offs decreased $12 million to $101 million.
        Internal watch list loans declined $376 million to $5.2 billion and
        nonaccrual loans decreased $84 million.  As a result, the provision for
        loan losses decreased $8 million to $49 million.
    --  Noninterest expenses totaled $415 million in the first quarter 2011, a
        decrease of $22 million from the fourth quarter 2010, primarily the
        result of a decrease in salaries expense of $17 million.
    --  The estimated Tier 1 ratio increased 24 basis points, to 10.37 percent
        at March 31, 2011, from December 31, 2010.

    --  The $10 million decrease in net interest income in the first quarter
        2011, when compared to the fourth quarter 2010, resulted primarily from
        two less days in the quarter and the maturity of interest rate swaps at
        positive spreads.
    --  The net interest margin of 3.25 percent declined four basis points
        compared to the fourth quarter 2010.  The decline in the net interest
        margin reflected the impact of an increase in excess liquidity and the
        maturity of interest rate swaps at positive spreads.
    --  Average earning assets increased $245 million, primarily due to
        increases of $504 million in Federal Reserve Bank deposits (excess
        liquidity) and $199 million in average investment securities
        available-for-sale, partially offset by a $448 million decrease in
        average loans.
    --  First quarter 2011 average core deposits increased $290 million compared
        to fourth quarter 2010, primarily reflecting increases in money market
        and NOW deposits ($495 million), partially offset by decreases in
        noninterest-bearing deposits ($148 million) and customer certificates of
        deposit ($93 million).

Noninterest Income

Noninterest income was $207 million for the first quarter 2011, compared to $215 million for the fourth quarter 2010. The $8 million decline reflected increases in net income from principal investing and warrants ($4 million) and service charges on deposit accounts ($3 million), which were more than offset by decreases in commercial lending fees ($8 million) and bank-owned life insurance ($6 million).

Noninterest Expenses

Noninterest expenses totaled $415 million in the first quarter 2011, a decrease of $22 million from the fourth quarter 2010. The $22 million decrease in noninterest expenses was primarily due to a decrease in salaries expense ($17 million) and a one-time charge recognized in the fourth quarter 2010 related to the redemption of subordinated notes ($5 million), partially offset by an increase in employee benefits expense ($7 million). The decrease in salaries expense primarily reflected a decrease in executive and business unit incentive expense ($8 million), a reduction in severance expense ($6 million) and the impact of two less days in the first quarter ($3 million), partially offset by an increase in share-based compensation expense ($5 million), resulting from annual share-based grants for retirement-eligible employees in the first quarter.

Credit Quality

"Overall, the first quarter results displayed a continuation of the steady improvement we have seen in our credit metrics over the last six quarters," Babb said. "First quarter net credit-related charge-offs decreased $12 million, with a significant decline in Commercial Real Estate, partially offset by an increase in Middle Market net charge-offs. The increase in Middle Market net charge-offs was primarily the result of several previously identified problem loans that are working their way through the collection process. Based on our analysis of Middle Market default rates, risk rating migration patterns as well as the watch list and nonaccruals, which were stable, we believe that the increase in charge-offs this quarter is not a trend. Our credit culture has served us well. It is one of our key strengths and has resulted in some of the best credit metrics among our peers."

    --  Net credit-related charge-offs decreased $12 million to $101 million in
        the first quarter 2011, from $113 million in the fourth quarter 2010.
        The decrease in net credit-related charge-offs primarily reflected
        decreases of $29 million in the Commercial Real Estate business line,
        $13 million in the Private Banking business line and $7 million in the
        Specialty Businesses business line, partially offset by an increase of
        $36 million in the Middle Market business line.
    --  Internal watch list loans declined $376 million to $5.2 billion from
        December 31, 2010 to March 31, 2011.
    --  During the first quarter 2011, $166 million of loan relationships
        greater than $2 million were transferred to nonaccrual status, a
        decrease of $14 million from the fourth quarter 2010, primarily due to a
        $35 million decrease in transfers from the Commercial Real Estate
        business line and a $10 million decrease in transfers from the Private
        Banking business line, partially offset by a $30 million increase in
        transfers from the Middle Market business line.  Of the transfers of
        loan relationships greater than $2 million to nonaccrual in the first
        quarter 2011, $101 million were from the Middle Market business line,
        primarily in the Midwest and Other markets, and $37 million were from
        the Commercial Real Estate business line in the Midwest market.
    --  Nonperforming assets decreased $131 million to $1.1 billion, or 2.81
        percent of total loans and foreclosed property, at March 31, 2011.
    --  Nonaccrual loans were charged down 46 percent at March 31, 2011.
    --  Foreclosed property decreased $38 million to $74 million at March 31,
        2011, from $112 million at December 31, 2010.
    --  Loans past due 90 days or more and still accruing were $72 million at
        March 31, 2011, an increase of $10 million compared to December 31,
        2010.
    --  The provision for loan losses decreased $8 million, primarily due to
        reductions in the Commercial Real Estate, Global Corporate Banking,
        Private Banking and Specialty Businesses business lines, partially
        offset by an increase in the Middle Market business line.
    --  The allowance for loan losses to total loans ratio was 2.17 percent and
        2.24 percent at March 31, 2011 and December 31, 2010, respectively.

Balance Sheet and Capital Management

Total assets and common shareholders' equity were $55.0 billion and $5.9 billion, respectively, at March 31, 2011, compared to $53.7 billion and $5.8 billion, respectively, at December 31, 2010. There were approximately 177 million common shares outstanding at March 31, 2011. Comerica repurchased 400,000 shares of common stock in the open market in the first quarter 2011 under the share repurchase program.

Comerica's tangible common equity ratio was 10.43 percent at March 31, 2011, a decrease of 11 basis points from December 31, 2010. The estimated Tier 1 ratio increased 24 basis points, to 10.37 percent at March 31, 2011, from December 31, 2010.

Full-Year 2011 Outlook Compared to Full-Year 2010

For full-year 2011, management expects the following, compared to full-year 2010, based on a continuation of modest growth in the economy. This outlook does not include any impact from the pending acquisition of Sterling Bancshares, Inc.

    --  A low single-digit decrease in average loans. Excluding the Commercial
        Real Estate business line, a low single-digit increase in average loans.
    --  Average earning assets of approximately $48.5 billion, reflecting lower
        excess liquidity in addition to a decrease in average loans.
    --  An average net interest margin of 3.25 percent to 3.30 percent, based on
        no increase in the Federal Funds rate.
    --  Net credit-related charge-offs between $350 million and $400 million for
        full-year 2011. The provision for credit losses is expected to be
        between $150 million and $200 million for full-year 2011.
    --  A low single-digit decline in noninterest income compared to 2010,
        primarily due to the impact of regulatory changes.
    --  A low single-digit increase in noninterest expenses compared to 2010,
        primarily due to an increase in employee benefits expense.
    --  Income tax expense to approximate 36 percent of income before income
        taxes less approximately $60 million of permanent differences related to
        low-income housing and bank-owned life insurance.
    --  Continue share repurchase program that, combined with dividend payments,
        results in a payout up to 50 percent of full-year earnings.

    (a) Excess liquidity, represented by average balances deposited with
    the Federal Reserve Bank, reduced the net interest margin by 14
    basis points in the first quarter of 2011, and by 12 points and 24
    basis points in the fourth and first quarters of 2010, respectively.
     Excluding excess liquidity, the net interest margin would have been
     3.39%, 3.41% and 3.42% in each respective period.  See
    Reconciliation of Non-GAAP Financial Measures.

    (a) Excess liquidity represented by interest earned on and average
    balances deposited with the Federal Reserve Bank (FRB).
    (b) Tier 1 capital and risk-weighted assets as defined by regulation.
    (c) March 31, 2011 Tier 1 capital and risk-weighted assets are estimated.

    The net interest margin (FTE), excluding excess liquidity, removes
    interest earned on balances deposited with the FRB from net interest
    income (FTE) and average balances deposited with the FRB from
    average earning assets from the numerator and denominator of the net
    interest margin (FTE) ratio, respectively. Comerica believes this
    measurement provides meaningful information to investors,
    regulators, management and others of the impact on net interest
    income and net interest margin resulting from Comerica's short-term
    investment in low yielding instruments.

    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.  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.
