Simpson Manufacturing Co., Inc.
Announces Fourth Quarter Earnings

DUBLIN, Calif., Jan. 24 /PRNewswire-FirstCall/ -- Simpson Manufacturing Co., Inc. (the "Company") announced today that its 2001 fourth quarter net sales increased 9.3% to $93,535,611 as compared to net sales of $85,598,655 for the fourth quarter of 2000. Net income decreased 2.4% to $6,802,404 for the fourth quarter of 2001 as compared to net income of $6,967,285 for the fourth quarter of 2000. Diluted net income per common share was $0.55 for the fourth quarter of 2001 as compared to $0.57 for the fourth quarter of 2000. For the year, net sales increased 12.7% to $415,862,601 in 2001 as compared to net sales of $369,087,813 in 2000. Net income increased 2.9% to $40,518,126 in 2001 as compared to net income of $39,374,743 in 2000. Diluted net income per common share was $3.29 in 2001 as compared to $3.20 in 2000.

In the fourth quarter of 2001, sales growth occurred throughout the United States, with the exception of California. The overall increase in sales was strongest in the midwestern region of the United States, and in Europe as result of the acquisition of BMF Bygningsbeslag A/S ("BMF") in Denmark in January 2001. Simpson Strong-Tie's fourth quarter sales increased 8.1% over the same quarter last year, while Simpson Dura-Vent's sales increased 13.4%. Homecenters was the fastest growing Simpson Strong-Tie connector sales channel while contractor distributors declined for the quarter. The sales increase was broad based across most of Simpson Strong-Tie's major product lines. The Anchor Systems product line had the highest percentage growth rates in sales with the addition of powder actuated tools contributing significantly. Strong-Wall sales declined during the fourth quarter of 2001 as compared to the fourth quarter of 2000 which the Company believes was caused partially by its distributors reducing their inventories due to economic uncertainty in California. Sales of Simpson Dura-Vent's chimney and pellet vent product lines increased compared to the fourth quarter of 2000 while sales of its Direct-Vent products decreased.

Income from operations increased 3.5% from $10,238,190 in the fourth quarter of 2000 to $10,599,688 in the fourth quarter of 2001 and gross margins increased from 34.2% in the fourth quarter of 2000 to 35.0% in the fourth quarter of 2001. The increase in gross margin was primarily due to lower costs related to slow moving inventory reserves as compared to the fourth quarter of 2000 partially offset by lower absorption resulting from inventory reduction and lower margins at BMF. Selling expenses increased 16.4% from $9,322,309 in the fourth quarter of 2000 to $10,854,858 in the fourth quarter of 2001, primarily due to higher personnel costs related to the increase in the number of sales and merchandising personnel as well as increased commissions to sales agents. General and administrative expenses increased 16.5% from $9,683,137 in the fourth quarter of 2000 to $11,285,172 in the fourth quarter of 2001. This increase was primarily due to an increase in the bad debt reserve related to a significant customer as well as increased administrative costs associated with the acquisition of BMF. The increase was partially offset by a decrease in cash profit sharing. The tax rate was 38.1% in the fourth quarter of 2001, a decrease from 40.1% in the fourth quarter of 2000.

In 2001, the sales growth occurred throughout the United States as well as in Europe as a result of the acquisition of BMF. Simpson Strong-Tie's sales increased 13.8% over last year, while Simpson Dura-Vent's sales increased 7.3% over last year. Homecenters was the fastest growing Simpson Strong-Tie connector sales channel. The sales increase was broad based across most of Simpson Strong-Tie's major product lines. The Anchor Systems product line had the highest percentage growth rate in sales with the addition of powder actuated tools contributing significantly. The Strong-Wall product line had positive sales growth in 2001, despite the decline in sales in the fourth quarter. Sales of Simpson Dura-Vent's chimney and pellet vent product lines increased in 2001 as compared to 2000 while sales of its Direct-Vent products decreased.

Income from operations increased 7.2% from $61,415,407 in 2000 to $65,816,141 in 2001 and gross margins decreased from 38.9% in 2000 to 38.0% in 2001. The decrease in gross margin was largely due to the lower margins at BMF. The acquisition of BMF also contributed to the increases in operating expenses. Selling expenses increased 12.9% from $37,409,957 in 2000 to $42,230,211 in 2001. The increase was primarily due to higher personnel costs related to the increase in the number of sales and merchandising personnel as well as increased commissions to sales agents and higher promotional expenses. General and administrative expenses increased 12.1% from $44,633,965 in 2000 to $50,031,666 in 2001. This increase was primarily due to an increase in the bad debt reserve related to a significant customer, to higher costs related to additional administrative personnel, including those at BMF, and to non-cash charges related to the amortization of intangible assets including the Keybuilder.com software license and the goodwill of acquired businesses. Partially offsetting this increase was a decrease in cash profit sharing. The tax rate was 41.0% in 2001, an increase from 40.8% in 2000.

Effective January 1, 2001, the Company changed its method of valuing inventories from the last-in, first-out (LIFO) method to the first-in, first-out (FIFO) method. All inventories are now costed using the FIFO method. The Company believes that the new method is preferable because the FIFO method of valuing inventory more closely matches current costs and revenues. The Company has applied this change retroactively by restating its financial statements as required by Accounting Principles Board No. 20, "Accounting Changes," which has resulted in a one time increase in previously reported retained earnings of $89,837 as of December 31, 2000. The effect of the change in accounting principle for the three and twelve months ended December 31, 2001, was immaterial.
