Reports 2014 Second Quarter Earnings Increase by 79% to $5.7 Million or $0.26 per share

Declares Quarterly Common Stock Dividend of $0.05 per share

Intervest Bancshares Corporation (IBC) (NASDAQ-GS: IBCA), parent company of Intervest National Bank (INB), today announced that its net earnings for the second quarter of 2014 (Q2-14) increased 79% to $5.7 million, or $0.26 per share, from $3.2 million, or $0.14 per share, for the second quarter of 2013 (Q2-13). For the first half of 2014 (6mths-14), net earnings increased 44% to $9.6 million, or $0.43 per share, from $6.6 million, or $0.30 per share, for the first half of 2013 (6mths-13). IBC also announced that its Board of Directors declared a quarterly dividend of $0.05 per common share payable on August 26, 2014 to shareholders of record at the close of business August 15, 2014.

Operating Summary

• Net interest and dividend income increased to $10.9 million in Q2-14, from $8.6 million in Q2-13, and to $21.1 million in 6mths-14, from $17.6 million in 6mths-13, reflecting a higher net interest margin. The margin (exclusive of loan prepayment income) increased to 2.84% in Q2-14 and 2.79% in 6mths-14, from 2.30% and 2.33% in the same periods of 2013.

• Credits for loan losses of $1.0 million and $1.5 million were recorded in Q2-14 and 6mths-14, respectively, compared to $0.8 million and $1.8 million in the same periods of 2013. The amounts in the 2014 periods reflected improved credit quality resulting from the payoff of four substandard loans totaling $6.9 million in Q2-14 and an upgrade of one loan ($1.6 million) in Q1-14, while the 2013 amounts were due to partial recoveries of prior loan charge offs.

• Noninterest income (inclusive of loan prepayment income) increased to $2.5 million in Q2-14 and to $3.3 million in 6mths-14, from $0.7 million and $1.4 million in the same periods of 2013. The increases were due to a higher level of loan prepayment income (including $0.7 million in Q2-14 from one loan) and the absence of security impairment charges in the 2014 periods.

• No provisions for real estate losses were required on properties owned through foreclosure (REO) in the 2014 periods, compared to $0.1 million in Q2-13 and $0.7 million in 6mths-13.

• Real estate expenses, net of rental and other income, amounted to $0.3 million in Q2-14 and $0.5 million in 6mths-14, compared to net income of $0.3 million in Q2-13 and net income of $1.3 million in 6mths-13. The net income for the 2013 periods reflected recoveries of expenses associated with previously owned properties. Exclusive of these recoveries, REO expense would have been $0.5 million and $1.0 million for 2013 periods, respectively.

• Operating expenses decreased slightly to $3.9 million in Q2-14, from $4.0 million in Q2-13, but increased to $8.5 million in 6mths-14, from $8.1 million in 6mths-13. The six-month period increase was primarily due to normal salary increases and higher stock compensation and employee bonus expense, partially offset by a decrease in FDIC insurance premiums.

• Our efficiency ratio, which measures our ability to control expenses as a percentage of revenues, continued to be favorable and improved to 27% for Q2-14 and 35% for 6mths-14, from 43% in the same periods of 2013.

• There were no preferred dividend requirements in the 2014 periods, compared to $0.3 million in Q2-13 and $0.8 million in 6mths-13. The 2013 dividend requirements related to IBC’s TARP preferred stock, which was repurchased and retired during June and August 2013.

Balance Sheet Summary

• Assets amounted to $1.57 billion at June 30, 2014, unchanged from December 31, 2013, as increases of $31 million in loans and $11 million in cash and short-term investments were offset by decreases of $26 million in security investments and $8 million in REO.

• Loans increased to $1.16 billion at June 30, 2014, from $1.13 billion at December 31, 2013. New loan originations for 6mths-14 increased to $165 million from $124 million for 6mths-13. Loan repayments decreased to $134 million in 6mths-14 from $172 million in 6mths-13.

• Deposits amounted to $1.28 billion at June 30, 2014, a decrease of $4.4 million from December 31, 2013.

• Stockholders’ equity increased to $207 million at June 30, 2014, from $197 million at December 31, 2013, reflecting primarily an increase in retained earnings of $8.5 million, net of a $1.1 million cash dividend on common stock paid on May 26, 2014.

• INB’s regulatory capital ratios at June 30, 2014 were as follows: Tier One Leverage - 15.92%; Tier One Risk-Based Capital - 20.18%; and Total Risk-Based Capital - 21.45%.

• Book value per common share increased to $9.38 at June 30, 2014, from $8.99 at December 31, 2013.

Asset Quality Summary

• Impaired loans (comprised of nonaccrual loans, restructured loans (TDRs) and one other accruing and performing loan) totaled $57.8 million at June 30, 2014, compared to $57.2 million at December 31, 2013.

• Nonaccrual loans decreased to $23.0 million at June 30, 2014, from $35.9 million at December 31, 2013, primarily reflecting one loan transferred to an accruing TDR status. Nonaccrual loans included TDRs at each date of $17.7 million and $33.2 million, respectively. These TDRs were current and had a weighted-average interest rate of 4.25% as of June 30, 2014.

• Accruing TDR loans increased to $27.1 million at June 30, 2014 from $13.4 million at December 31, 2013, due to the transfer of the loan noted above. These TDR loans had a weighted-average interest rate of approximately 5% at June 30, 2014.

• The allowance for loan losses was $26.6 million, or 2.30% of total loans, at June 30, 2014, compared to $27.8 million, or 2.47%, at December 31, 2013. The allowance included specific reserves allocated to impaired loans at each date (totaling $5.5 million and $6.1 million, respectively).

• REO decreased to $2.6 million at June 30, 2014, from $10.6 million at December 31, 2013, reflecting the sales of two properties.

Net Interest and Dividend Income

The $2.3 million quarterly increase in net interest and dividend income reflected an improved interest rate spread and a higher ratio (1.15x compared to 1.10x) of interest-earning assets to interest-bearing liabilities due to deployment of cash into new loans. The net interest margin increased to 2.84% in Q2-14 from 2.30% in Q2-13, primarily due to a 53 basis point increase in the interest rate spread and a $56 million increase in net interest-earning assets. The higher spread reflected primarily the run-off and replacement of higher-cost legacy CDs with new CDs at lower interest rates, which reduced the average cost of funds by 54 basis points to 1.55% in Q2-14 from 2.09% in Q2-13. The average yield on earning assets decreased slightly to 4.19% in Q2-14 from 4.20% in Q2-13 as the negative impact of payoffs of older, higher yielding loans coupled with new loan originations at lower market interest rates was offset by higher yields on security investments and the growth in net interest earning assets. Total average interest-earning assets increased by $44 million in Q2-14 from Q2-13, reflecting a $107 million increase in loans, partially offset by a $63 million decrease in total securities and overnight investments. At the same time, total average deposits decreased by $12 million, while average total stockholders’ equity decreased by $13 million (reflecting the repurchase and retirement of $25 million of preferred stock during the middle of 2013, partially offset by an $11 million increase in retained earnings).

The $3.5 million six-month increase in net interest and dividend income was due to the same reasons noted above. The net interest margin increased to 2.79% in 6mths-14, from 2.33% in 6mths-13. The average cost of funds decreased by 54 basis points to 1.57% in 6mths-14, from 2.11% in 6mths-13, while the average yield on earning assets decreased by only 6 basis points to 4.17% in 6mths-14, from 4.23% in 6mths-13. Total average interest-earning assets increased for the 6mths-14 period by $10 million from 6mths-13, reflecting an increase of $71 million in loans, partially offset by a $61 million decrease in total securities and overnight investments. At the same time, total average deposits decreased by $25 million, while average stockholders’ equity decreased by $13 million.

Loans

The $31 million net increase in loans at June 30, 2014 compared to December 31, 2013 reflected $164.6 million of new originations and $0.3 million of recoveries of prior charge offs, partially offset by $110.1 million of payoffs and $24.2 million of principal amortization and partial pay downs. New originations were comprised of $131 million of commercial real estate (CRE) loans, $28 million of multifamily loans and $5 million of loans secured by investor-owned, 1-4 family condominiums. New CRE loans included $25 million of single tenant credit and $28 million of single tenant non-credit properties.

New originations for the first half of 2014 had a weighted-average rate, term, debt service coverage ratio and loan-to-value ratio of 4.72%, 6.6 years, 1.24x and 59%, respectively, compared to 4.47%, 5.9 years, 1.29x and 58%, respectively, for new loans originated in the first half of 2013. Nearly all of the new loans in both periods had fixed interest rates. Loans paid off in 6mths-14 and 6mths-13 had a weighted-average rate of 5.22% and 5.98%, respectively.

At June 30, 2014, the loan portfolio was concentrated in CRE loans and was comprised of 76% of loans secured by CRE, 18% secured by multifamily properties and 5% by investor-owned, 1-4 family condominiums. The single tenant category totaled $206 million at June 30, 2014, or approximately 23% of the total CRE loan portfolio, up from $157 million and 19% at December 31, 2013.

Deposits

The $4.4 million decrease in deposits reflected an $18.9 million decrease in total money market and checking accounts, partially offset by a $14.5 million increase in certificate of deposit accounts.
