Reports 2008 First Quarter Earnings of $2.3 Million

Business Editors – New York – (Business Wire – April 15, 2008)

Intervest Bancshares Corporation (NASDAQ-GS:IBCA) (the “Company”) today reported that its net earnings for the first quarter of 2008 (“Q1-08”) decreased to $2.3 million, or $0.28 per diluted share, from $5.3 million, or $0.62 per diluted share, for the first quarter of 2007 (“Q1-07”). The Company’s book value per common share was $22.21 at March 31, 2008.

Net earnings for Q1-08 decreased by $3.0 million from Q1-07 due to the following: a $2.7 million decrease in net interest and dividend income; a $1.4 million increase in the provision for loan losses; a $0.7 million increase in noninterest expenses; and a $0.7 million decrease in noninterest income; partially offset by a $2.5 million decrease in the provision for income tax expense.

Net interest and dividend income decreased to $8.9 million in Q1-08 from $11.6 million in Q1-07 largely due to an $88 million increase in average nonaccrual loans. Interest income that was not recorded on nonaccrual loans amounted to $2.2 million in Q1-08, compared to a $0.2 million in Q1-07. The Company’s net interest margin (excluding income from loan prepayments) decreased to 1.71% in Q1-08, from 2.38% in Q1-07. The margin was negatively affected by the increase in nonaccrual loans, repayments of higher yielding loans coupled with lower competitive pricing for new loans, and lower yields earned on investment securities and short-term investments. The Company’s cost of funds decreased slightly to 4.94% in Q1-08 from 4.96% in Q1-07. The provision for loan losses increased to $2.3 million in Q1-08, from $0.9 million in Q1-07 due to credit downgrades on nonaccrual loans. Noninterest expenses increased to $3.5 million in Q1-08, from $2.8 million in Q1-07 due to a $0.3 million increase in expenses associated with nonaccrual loans/foreclosed real estate and a $0.4 million increase in FDIC insurance premiums. Noninterest income decreased to $0.9 million in Q1-08, from $1.6 million in Q1-07 primarily due to a $1.0 million decrease in income from loan prepayments, partially offset by a $0.4 million increase in gains from the early call of investment securities. The Company’s effective income tax rate was 43% in Q1-08, compared to 44% in Q1-07. The Company had 71 employees at March 31, 2008, compared to 73 employees at March 31, 2007.

The Company’s efficiency ratio, which is a measure of its ability to control expenses as a percentage of its revenues, was 36% in Q1-08, compared to 21% in Q1-07. Return on average assets and equity decreased to 0.44% and 5.01% respectively, in Q1-08, from 1.08% and 12.45%, respectively, in Q1-07. The efficiency ratio and returns on average assets and equity were negatively affected largely by nonaccrual loans and higher FDIC insurance premiums.

Total assets at March 31, 2008 increased to $2.2 billion, from $2.0 billion at December 31, 2007. The increase reflected growth in the Company’s loan portfolio and a higher level of security investments and other short-term investments.

Total loans, net of unearned fees, at March 31, 2008 increased to $1.68 billion, from $1.61 billion at December 31, 2007. The increase was due to new originations secured by commercial and multifamily real estate exceeding principal repayments. New originations totaled $97 million for Q1-08, compared to $145 million for Q1-07. Principal repayments totaled $31 million for Q1-08, compared to $86 million for Q1-07. The Company does not own, originate or invest in sub prime single-family home loans or construction/development loans.

Total nonaccrual loans increased to $97.7 million (18 loans) at March 31, 2008, from $90.8 million (18 loans) at December 31, 2007 and $11.7 million (6 loans) at March 31, 2007. Foreclosure proceedings are pending on all nonaccrual loans and are in various stages of resolution, including some proceedings that have been delayed or protracted by reason of bankruptcy filings. In Q1-08, the Company downgraded its internal credit ratings on several nonaccrual loans to reflect lower real estate values as well as the uncertainty as to the timing of the collection of these loans. These downgrades resulted in $1.6 million of additional loan loss provision in Q1-08. The Company believes that the estimated fair value of each of the underlying collateral properties continues to exceed its net recorded investment in each related nonaccrual loan as of March 31, 2008. However, there can be no assurance that the Company will not incur additional loan loss provisions, loan chargeoffs or significant expenses with respect to the ultimate collection of its nonaccrual loans, which collection is anticipated to be through the eventual sale of the collateral property in most cases. In Q1-08, a property in Florida collateralizing a nonaccrual loan in the amount of $4.0 million was acquired by the Company through foreclosure. This property is being marketed for sale. The Company’s total nonperforming assets of $101.7 million represented 4.70% of total assets at March 31, 2008.

The total allowance for loan losses amounted to $23.9 million at March 31, 2008, compared to $21.6 million at December 31, 2007. The allowance represented 1.42% of total loans (net of deferred fees) outstanding at March 31, 2008, compare to 1.34% at December 31, 2007. The increase in the allowance was due to provisions totaling $2.3 million during the first quarter of 2008, of which $1.6 million was attributable to credit downgrades on nonaccrual loans and $0.7 million from net loan growth of $63 million from December 31, 2007.

Total securities held to maturity at March 31, 2008 increased to $407 million, from $344 million at December 31, 2007, due to new purchases exceeding maturities and calls. The sharp decline in market interest rates in Q1-08 resulted in a higher level of securities being called by the issuers. The investment portfolio, which is held by Intervest National Bank, had a weighted-average remaining contractual maturity of 5.1 years and a yield of 4.48% at March 31, 2008. The Bank invests in U.S. government agency debt obligations to emphasize safety and liquidity. The Company does not own or invest in collateralized debt obligations or collateralized mortgage obligations.

Total deposits at March 31, 2008 increased to $1.78 billion, from $1.66 billion at December 31, 2007, reflecting a $71 million increase in certificate of deposit accounts and a $51 million aggregate increase in money market and checking accounts.

Total borrowed funds and related interest payable at March 31, 2008 increased to $159 million, from $136 million at December 31, 2007, due to a $23 million increase in short-term FHLBNY advances.

Total stockholders’ equity at March 31, 2008 increased to $183.7 million, from $179.5 million at December 31, 2007. The increase was due to the following: $2.3 million from net earnings; $1.8 million from the issuance of 195,000 shares of Class B common stock upon the exercise of outstanding Class B warrants; and $0.1 million from stock-based compensation.
