LSB Corporation Announces Third Quarter 2007 and Year-To-Date Financial Results,
Quarterly Cash Dividend

NORTH ANDOVER, MA, — (MARKET WIRE) – October 25, 2007 – LSB Corporation (NASDAQ-LSBX) (the “Corporation” or the “Company”) today announced third quarter 2007 net income of $1.0 million, or $0.22 per diluted share, as compared to net income of $808,000, or $0.18 per diluted share, for the third quarter of 2006. Net income for the nine months ended September 30, 2007, totaled $2.6 million, or $0.57 per diluted share, as compared to a net loss of $874,000, or $0.19 per diluted share, for the year-to-date period ended September 30, 2006.

The largest factors in the year-to-date results for 2006 were the balance sheet restructuring whereby $80 million of investments were sold at a pre-tax loss of $2.4 million (after-tax charge of $1.6 million, or $0.35 per diluted share) accompanied by other costs incurred in 2006 relating to the name change of the Company’s subsidiary bank to River Bank and former employee severance payments; the combination of which totaled approximately $1.2 million on a pre-tax basis (after-tax charge of $780,000, or $0.17 per diluted share).

The improved results in the third quarter of 2007 resulted from settlement gains of $357,000 recorded in connection with the pension termination announced in October 2006. The pre-tax gain is due to the reversal of the accrued pension liability. Partially offsetting the settlement gains, the Company recorded a provision for loan losses of $250,000 in the third quarter of 2007, or approximately $100,000 higher than the second quarter of 2007. The increases in the provision for loan losses in both quarters are primarily due to the continued, sustained corporate loan growth.

The Company’s net interest margin increased from 2.67% in the first nine months of 2006 to 2.78% for the comparable period in 2007. This increase reflects the Company’s continued success in generating new loan growth and replacing maturing investments with higher-yielding loans. However, the Company expects that the current interest rate environment will continue to exert pressures on its deposit and borrowing costs, which may decrease the Company’s net interest margin in future periods.

Total assets increased $66.2 million from December 31, 2006 to $609.1 million as of September 30, 2007. The increase in 2007 reflected the strong loan growth since year end 2006, partially offset by a decline in the investment portfolio from December 31, 2006.

Total loans of $349.3 million as of September 30, 2007 increased $61.1 million from December 31, 2006. The increase was primarily in the corporate loan portfolio. As of September 30, 2007, non-performing loans equaled 0.10% of total loans while the allowance for loan losses as a proportion of total loans equaled 1.36% as compared to 0.37% and 1.50%, respectively, as of December 31, 2006.

Total deposits increased $31.0 million from December 31, 2006 and totaled $326.6 million as of September 30, 2007. Due to aggressive promotional campaigns targeting new customers, certificates of deposit increased 24.3% from December 31, 2006. Money market investment accounts and NOW accounts increased modestly offset by decreases in savings accounts and demand deposit accounts. Brokered certificates of deposit totaled $5.5 million at

September 30, 2007. Total borrowed funds increased during the first nine months of 2007 by $34.9 million or 18.9% and totaled $219.6 million as of September 30, 2007.

President and CEO Gerald T. Mulligan stated, “I am pleased by the 27% increase in the corporate loan growth which has been achieved without a diminution in credit quality. In light of recent evidence of asset quality concerns at other financial institutions, we have maintained a high allowance coverage ratio of 1.36% of all loans.”

The Company also announced today a quarterly cash dividend of $0.14 to be paid on November 23, 2007 to shareholders of record as of November 8, 2007. This dividend represents a 3.49% annualized dividend yield based on the closing stock price of $16.04 on September 30, 2007.

Under the previously approved common stock repurchase program, the Company has repurchased approximately 60,000 shares of the Company’s outstanding common stock since the program’s inception. The timing and amount of future stock repurchases will depend upon market conditions, securities law limitations and other corporate considerations; the Company has placed no deadline on the duration of the repurchase program.
