STERLING BANCSHARES REPORTS SECOND QUARTER 2011 RESULTS

HOUSTON, TX, July 19, 2011 – Sterling Bancshares, Inc. (Nasdaq: SBIB) today reported a net loss from continuing operations of $2.9 million, or $0.03 per diluted share, for the second quarter ended June 30, 2011, compared to a net loss from continuing operations of $495 thousand, or $0.00 per diluted share for the first quarter of 2011.

The Company recorded a loss on discontinued operations of $9.0 million during the second quarter of 2011. This loss was the result of Sterling Bank entering into an agreement to sell all of the shares of MBM Advisors, Inc. (MBM), a wholly-owned subsidiary of Sterling Bank that provides investment advisory and pension administration and consulting services. This sale is expected to close in the third quarter of 2011 following the completion of the Company’s pending merger with Comerica which is expected to close on July 28, 2011. As such, MBM’s operations and the estimated loss on sale are presented as discontinued operations beginning in the second quarter of 2011.

For the second quarter of 2011, loans decreased $191 million or 7.3% to $2.4 billion at June 30, 2011. This decrease was due primarily to combined reductions of $91 million in commercial real estate and construction and development loans, resulting from the Company’s continued efforts to reduce exposure to these loan types. Commercial and industrial loans decreased $87 million during the second quarter of 2011 due to continued low loan demand and line usage.

At June 30, 2011, total deposits were $4.1 billion, an increase of $11.6 million compared to March 31, 2011. This increase was primarily related to growth in interest-bearing demand deposits.

Nonperforming assets were $202 million at June 30, 2011, an increase of $15.9 million compared to March 31, 2011. The increase in nonperforming assets during the quarter was due to an increase in nonperforming commercial real estate loans.

At June 30, 2011, the total allowance for loan losses was $78.0 million or 3.24% of period-end total loans, up from $75.5 million or 2.90% of period-end total loans at March 31, 2011. Net charge-offs for the second quarter of 2011 were $6.7 million or 1.06% of average total loans, compared to $12.4 million or 1.87% of average total loans for the first quarter of 2011. The provision for credit losses decreased $1.6 million on a linked-quarter basis due primarily to lower charge-offs during the second quarter.

Tax-equivalent net interest income for the second quarter of 2011 was $38.9 million, down slightly on a linked-quarter basis. Tax-equivalent net interest margin was 3.39% for the second quarter of 2011, down 13 basis points from 3.52% for the first quarter of 2011. The decrease in the net interest margin during the second quarter of 2011 was due to a decrease in average loans of $138 million which resulted in an increase in lower-yielding average interest-bearing cash of $129 million.

Noninterest income for the second quarter of 2011 was $5.9 million, a decrease of $2.6 million compared to the first quarter of 2011. Net losses on securities were $1.1 million and $429 thousand for the second and first quarters of 2011, respectively. These losses were due to the sale of certain securities that were downgraded to below investment grade during their respective quarters. Other noninterest income decreased $1.7 million for the second quarter of 2011 compared to the first quarter of 2011 due to payout claims on certain bank-owned life insurance policies during the first quarter.

Total noninterest expense for the second quarter of 2011 was $40.6 million, an increase of $916 thousand compared to the first quarter of 2011. Other noninterest expense increased $3.8 million due to additional write-downs on foreclosed assets. The increase in other noninterest expense was offset by a decrease in salaries and benefits and FDIC insurance assessments of $1.4 million and $501 thousand, respectively on a linked-quarter basis. Additionally, professional fees decreased $837 thousand on a linked-quarter basis due primarily to legal fees that were incurred during the first quarter of 2011 in connection with the pending merger with Comerica.

As of June 30, 2011, Sterling had total assets of $5.1 billion, total loans of $2.4 billion and total deposits of $4.1 billion. Shareholders’ equity of $621 million at June 30, 2011, was 12.26% of total assets. Book value per common share at period-end was $6.07. Tangible capital ratio was 9.16% and all regulatory capital ratios were in excess of those considered to be well-capitalized at June 30, 2011.

FOOTNOTES TO EARNINGS RELEASE

Page 11

(1)	Earnings per share in each quarter is computed individually using the weighted-average number of shares outstanding during that quarter.

(2)	Interim periods annualized.

(3)

Taxable-equivalent basis assuming a 35% tax rate. The Company presents net interest income on a tax-equivalent basis. Accordingly, net interest income from tax-exempt securities and loans is presented in the net interest income results on a basis comparable to taxable securities and loans. This non-GAAP financial measure allows management to assess the comparability of net interest income arising from both taxable and tax-exempt sources.

(4)	The efficiency ratio is calculated by dividing noninterest expense by tax equivalent basis net interest income plus noninterest income less net gain (loss) on investment securities and loss on disposal of assets.

N/M	Not meaningful.
