"Total average loans were down one percent and period-end loans were up modestly from March 31, 2011. We were pleased to see commercial loan growth in the second quarter, driven primarily by increases in Middle Market, Global Corporate Banking and Specialty Businesses, partially offset by a decrease in floor plan loans in National Dealer Services," said Ralph W. Babb Jr., chairman and chief executive officer. "Commercial Real Estate declined, offsetting the commercial loan growth. We expect the pace of decline in Commercial Real Estate to lessen in the second half of 2011 and National Dealer Services to rebound in the fourth quarter. Our core deposits continued to increase in the second quarter, which led to higher excess liquidity and a lower net interest margin. Credit quality continued to improve and expenses were well controlled.

"We are excited about our pending acquisition of Sterling Bancshares, Inc., a strategically compelling transaction that significantly boosts our presence in the growing state of Texas. Following the expiration of the required 15-day Department of Justice waiting period associated with the Federal Reserve Board's approval order, we expect the acquisition will close on July 28, 2011. Sterling's solid deposit base and well located branch network are expected to triple our Houston market share, provide us entry into the attractive San Antonio and Kerrville regions and complement our existing footprint in the Dallas-Fort Worth area. In short, it is a unique opportunity that provides us enhanced growth opportunities going forward.

"The Sterling integration plans remain on track. We expect a smooth transition, given the size of the acquisition and our in-depth knowledge of the Texas market. We look forward to welcoming Sterling customers and employees to Comerica as we begin this new chapter in our Texas banking history."

Second Quarter 2011 Highlights Compared to First Quarter 2011

    --  Average loans increased in the Middle Market ($160 million; one
        percent), Global Corporate Banking ($136 million; 3 percent), and
        Specialty Businesses ($62 million; one percent) business lines.  These
        increases were more than offset by decreases in the Commercial Real
        Estate ($393 million; 9 percent) and National Dealer Services ($194
        million; 5 percent) business lines, resulting in a decrease in average
        total loans of $377 million, or one percent.  Period-end loans increased
        $17 million from March 31, 2011 to June 30, 2011.
    --  Average core deposits increased $881 million in the second quarter 2011,
        with increases in all major markets, led by the Texas market.
    --  The net interest margin of 3.14 percent decreased 11 basis points
        compared to the first quarter 2011, primarily resulting from an increase
        in excess liquidity (represented by average balances deposited with the
        Federal Reserve Bank), and a decrease in loan pricing based on a
        decrease in LIBOR.
    --  Average earning assets increased $789 million in the second quarter
        2011.
    --  Credit quality improvement continued in the second quarter 2011.  Net
        credit-related charge-offs decreased $11 million to $90 million. 
        Internal watch list loans declined $339 million to $4.8 billion and
        nonperforming assets decreased $60 million.
    --  Noninterest expenses decreased $6 million to $409 million in the second
        quarter 2011, compared to the first quarter 2011.  Noninterest expenses
        included $5 million of costs incurred in connection with the pending
        Sterling acquisition in the second quarter 2011, which were more than
        offset by declines in numerous noninterest expense categories.
    --  The second quarter 2011 provision for income taxes included net
        after-tax charges of $8 million, which primarily reflected a $19 million
        charge related to a final settlement agreement with the Internal Revenue
        Service (IRS) involving repatriation of foreign earnings on a structured
        investment transaction, partially offset by a release of tax reserves of
        $9 million resulting from Comerica's planned participation in a recently
        enacted State of California voluntary compliance initiative.  Comerica
        has no other investment structures with uncertain tax positions.
    --  The estimated Tier 1 capital ratio increased 18 basis points, to 10.53
        percent at June 30, 2011, from March 31, 2011.

    deposits.

    --  The $4 million decrease in net interest income in the second quarter
        2011, when compared to the first quarter 2011, resulted primarily from a
        decline in the net interest margin, the first quarter 2011 maturities of
        interest rate swaps at positive spreads and a decrease in average loans,
        partially offset by one more day in the quarter.
    --  The net interest margin of 3.14 percent declined 11 basis points
        compared to the first quarter 2011.  The decline in the net interest
        margin primarily reflected the impact of an increase in excess liquidity
        (7 basis points), a decrease in loan pricing based on a decrease in
        LIBOR, and the first quarter 2011 maturities of interest rate swaps at
        positive spreads.
    --  Average earning assets increased $789 million, primarily due to
        increases of $1.1 billion in excess liquidity and $96 million in average
        investment securities available-for-sale, partially offset by a $377
        million decrease in average loans.
    --  Second quarter 2011 average core deposits increased $881 million
        compared to first quarter 2011, primarily reflecting increases in money
        market and NOW deposits ($410 million), noninterest-bearing deposits
        ($327 million) and customer certificates of deposit ($100 million).

Noninterest Income

Noninterest income was $202 million for the second quarter 2011, compared to $207 million for the first quarter 2011. The $5 million decrease primarily resulted from a decrease in deferred compensation asset returns ($3 million) (offset by a decrease in deferred compensation plan costs in noninterest expense).

Noninterest Expenses

Noninterest expenses totaled $409 million in the second quarter 2011, a decrease of $6 million from the first quarter 2011. The decrease in noninterest expenses was primarily due to decreases in salaries expense ($3 million), FDIC insurance expense ($3 million), software expense ($3 million) and other real estate expense ($2 million), partially offset by certain pre-integration and transaction costs incurred in connection with the pending Sterling acquisition ($5 million).

Provision for Income Taxes

The second quarter 2011 provision for income taxes included net after-tax charges of $8 million, which primarily reflected a $19 million charge related to a final settlement agreement with the IRS involving repatriation of foreign earnings on a structured investment transaction, partially offset by a release of tax reserves of $9 million resulting from Comerica's planned participation in a recently enacted State of California voluntary compliance initiative.

Credit Quality

"Broad-based, steady improvement in credit quality continued in the second quarter," said Babb. "This was the eighth consecutive quarter of decline in net charge offs, with an $11 million decrease. We had strong recoveries of $35 million in the second quarter, up from $22 million in the first quarter. Credit quality migration remains positive, as demonstrated by the $339 million decline in watch list loans, which provide our best early indicator of future credit quality, as well as the $60 million decline in nonperforming assets. As a result of these overall improvements to our credit metrics, the provision for loan losses decreased to $47 million. Also, of note, the results of the recently received Shared National Credit Exam are reflected in our second quarter credit metrics."

    --  Net credit-related charge-offs decreased $11 million to $90 million in
        the second quarter 2011, from $101 million in the first quarter 2011.
        The decrease in net credit-related charge-offs primarily reflected a
        decrease of $22 million in the Middle Market business line, partially
        offset by an increase of $9 million in the Private Banking business
        line.
    --  Internal watch list loans declined $339 million to $4.8 billion from
        March 31, 2011 to June 30, 2011.
    --  During the second quarter 2011, $163 million of loan relationships
        greater than $2 million were transferred to nonaccrual status, a
        decrease of $3 million from the first quarter 2011.  Of the transfers of
        loan relationships greater than $2 million to nonaccrual in the second
        quarter 2011, $76 million were from the Middle Market business line,
        primarily in the Midwest and Western markets, and $29 million were from
        the Commercial Real Estate business line, distributed across the
        Florida, Western and Other markets.
    --  Nonperforming assets decreased $60 million, compared to March 31, 2011,
        to $1.0 billion, or 2.66 percent of total loans and foreclosed property,
        at June 30, 2011.
    --  The allowance for loan losses to total loans ratio was 2.06 percent and
        2.17 percent at June 30, 2011 and March 31, 2011, respectively.

Balance Sheet and Capital Management

Total assets and common shareholders' equity were $54.1 billion and $6.0 billion, respectively, at June 30, 2011, compared to $55.0 billion and $5.9 billion, respectively, at March 31, 2011. There were approximately 177 million common shares outstanding at June 30, 2011. Comerica did not repurchase any shares of common stock in the open market in the second quarter 2011 under the share repurchase program due to the pending Sterling acquisition. Management expects to resume repurchases in the third quarter 2011.

Comerica's tangible common equity ratio was 10.90 percent at June 30, 2011, an increase of 47 basis points from March 31, 2011. The estimated Tier 1 capital ratio increased 18 basis points, to 10.53 percent at June 30, 2011, from March 31, 2011.

Second-Half 2011 Outlook (Combined Comerica and Sterling Results) Compared to First-Half 2011 (Comerica Only Results)

For the second half of 2011, management expects the following combined results, based on the incorporation of the projected results of Sterling operations from the expected acquisition closing date of July 28, 2011 through year-end 2011, compared to Comerica-only results for the first half of 2011, assuming a continuation of modest growth in the economy. The acquisition is subject to customary closing conditions. The estimated purchase accounting impacts incorporated in this outlook are preliminary and may not be indicative of actual amounts that will be recorded as additional information becomes available and as additional analyses are performed.

    --  A mid-single digit increase in average loans due to the acquisition of
        Sterling loans at fair value.
    --  Average earning assets of approximately $52.5 billion, reflecting
        increases, primarily related to Sterling, in average loans and average
        investment securities available-for-sale, partially offset by a decrease
        in excess liquidity.
    --  An average net interest margin of 3.35 percent to 3.40 percent,
        reflecting the benefit from the accretion of the purchase discount on
        the acquired Sterling loan portfolio ($35 million to $45 million; 13
        basis points to 17 basis points), a reduction in excess liquidity, no
        increase in the Federal Funds rate, and LIBOR consistent with second
        quarter 2011 levels.
    --  Net credit-related charge-offs between $165 million and $185 million for
        the second half of 2011. The provision for credit losses is expected to
        be between $65 million and $85 million for the second half of 2011.
    --  A mid-single digit decline in noninterest income in the second half of
        2011 compared to the first half of 2011, primarily due to the impact of
        regulatory changes, partially offset by the inclusion of Sterling.
    --  Excluding merger and restructuring charges, a high single-digit increase
        in noninterest expenses in the second half of 2011 compared to the first
        half of 2011, primarily due to the addition of Sterling.
    --  Total merger and restructuring charges of approximately $80 million,
        after-tax, with about $25 million, after-tax, recognized in each of the
        third and fourth quarters of 2011, and the remainder recognized in 2012.
    --  Total acquisition synergies of approximately 35 percent of Sterling
        expenses, or about $56 million, with the majority realized in 2012.
    --  For the second half of 2011, income tax expense to approximate 36
        percent of income before income taxes less approximately $33 million in
        tax benefits.
    --  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 18
    basis points and 24 basis points year-to-date in 2011 and 2010,
    respectively.  Excluding excess liquidity, the net interest margin
    would have been 3.37% in 2011 and 3.47% in 2010.  See Reconciliation
    of Non-GAAP Financial Measures.

    (a) Excess liquidity, represented by average balances deposited with
    the Federal Reserve Bank, reduced the net interest margin by 21
    basis points and by 14 points in the second and first quarters of
    2011, respectively and by 23 basis points in the second quarter of
    2010.  Excluding excess liquidity, the net interest margin would
    have been 3.35%, 3.39% and 3.51% 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 FRB.

    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.

    (a) Tier 1 capital and risk-weighted assets as defined by regulation.
    (b) June 30, 2011 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.  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.
