LSB Corporation Announces Fourth Quarter 2006 and Annual Financial Results, Quarterly Dividend

NORTH ANDOVER, MA, — (MARKET WIRE) — January 25, 2007 — LSB Corporation (NASDAQ-LSBX) (the “Corporation” or the “Company”) today announced fourth quarter 2006 net income of $1.0 million, or $0.22 per diluted share, as compared to net income of $1,683,000, or $0.37 per diluted share, for the fourth quarter of 2005. As a result of the previously announced pension termination, the Company recorded in the fourth quarter of 2006 a curtailment gain of approximately $600,000 on a pre-tax basis (after-tax benefit of $355,000, or $0.08 per diluted share) due to the reversal of the accrued pension liability. The remaining accrued pension liability of $760,000 on a pre-tax basis is expected to be recorded as settlement gains upon the final distribution of the pension assets during 2007. In the fourth quarter of 2005, the Company received $2.2 million (after-tax benefit of $1.3 million, or $0.29 per diluted share) from the final distribution of a lawsuit judgment awarded to the Company’s banking subsidiary River Bank.

In the twelve months of 2006, net income was $126,000, or $0.03 per diluted share, versus net income of $4,157,000, or $0.92 per diluted share, in the twelve months of 2005. The largest factor in the year-to-date results was the balance sheet restructuring undertaken during the second quarter of 2006 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).

Total non-interest expenses for the fourth quarter of 2006 declined by $296,000 from the fourth quarter of 2005 primarily due to a reduction in the salary and benefit expenses resulting from costs of $487,000 associated with contractual obligations to the former President. Total non-interest expenses for the twelve months of 2006 increased by $1.9 million versus the corresponding period in 2005. The increased costs in 2006 resulted from severance payments to former employees of $780,000 as well as costs associated with stock options granted in current and prior years in the amount of $170,000. Additionally, the Company’s results for the year ended December 31, 2006 were adversely affected by costs in the amount of $870,000 associated with the name change of the Company’s banking subsidiary to River Bank, accelerated depreciation on obsolete fixed assets and damaged equipment resulting from the flood of the corporate headquarters and costs associated with the clean-up and remediation of a preexisting environmental issue at a branch location.

The Company’s net interest margin increased slightly from 2.66% in the twelve months of 2005 to 2.68% in 2006. Although the Company expects the balance sheet restructuring to have a positive impact on its net interest margin in the long-term, much of the restructuring was not completed until late in the second quarter and thus, its effect on the margin during the twelve months was minimal. The net interest margin for the quarter ended December 31, 2006 increased to 2.72% compared to 2.62% for the same quarter of 2005. The Company expects, however, that even taking into account the full impact of the balance sheet restructuring, deposit and borrowing interest rate increases will continue to exert downward pressure on its net interest margin.

Total loans increased $53.6 million from December 31, 2005 to $288.2 million as of December 31, 2006. The increase was in all loan categories and total loans exceeded total investments as of December 31, 2006. As of December 31, 2006, non-performing loans equaled 0.37% of total loans while the allowance for loan losses as a proportion of total loans equaled 1.50% as compared to 1.76% as of December 31, 2005.

President Gerald T. Mulligan stated, “I am pleased to see the strong loan growth throughout 2006 without an apparent diminution in credit quality. Growth in the loan portfolio and the restructuring of the investment portfolio increased the yield on earning assets from 4.88% in 2005 to 5.63% in 2006. While this increase in asset yield is encouraging, the continued inversion of the yield curve and rising cost of short-term funding has greatly muted the benefit of the asset yield increase. Our inability to replace wholesale borrowings with retail deposits has been disappointing and remains our most significant challenge.”

Total assets increased $21.5 million from December 31, 2005 to $543.3 million as of December 31, 2006. The increase in 2006 reflected the strong loan growth since year end 2005 offset by the second quarter balance sheet restructuring which reduced the investment portfolio by approximately $30 million.

Total deposits decreased $7.4 million from December 31, 2005 and totaled $295.7 million as of December 31, 2006. Total borrowed funds increased during the twelve months of 2006 by $31.4 million or 20.5% and totaled $184.8 million as of December 31, 2006.

The Company also announced today a quarterly dividend of $0.14 to be paid on February 22, 2007 to shareholders of record as of February 8, 2007. This dividend represents a 3.38% annualized dividend yield based on the closing stock price of $16.57 on December 31, 2006.
