Simpson Manufacturing Co., Inc.
Announces Third Quarter Earnings

DUBLIN, Calif., Oct. 18 /PRNewswire/ -- Simpson Manufacturing Co., Inc. (the "Company") announced today that its 2001 third quarter net sales increased 10.5% to $111,660,531 as compared to net sales of $101,048,081 for the third quarter of 2000. Net income increased 3.8% to $12,116,915 for the third quarter of 2001 as compared to net income of $11,671,732 for the third quarter of 2000. Diluted net income per common share was $0.98 for the third quarter of 2001 as compared to $0.95 for the third quarter of 2000. For the nine months ended September 30, 2001, net sales increased 13.7% to $322,326,991 as compared to net sales of $283,489,158 for the nine months ended September 30, 2000. Net income increased 4.0% to $33,715,721 for the first nine months of 2001 as compared to net income of $32,407,458 for the first nine months of 2000. Diluted net income per common share was $2.74 for the first nine months of 2001 as compared to $2.63 for the first nine months of 2000.

In the third quarter of 2001, sales growth occurred throughout the United States, with the exception of California where sales were flat. The increases were strongest in the midwestern and southeastern region of the United States, and in Europe as a result of the acquisition of BMF Bygningsbeslag A/S ("BMF") in Denmark in January 2001. Simpson Strong-Tie's third quarter sales increased 11.4% over the same quarter last year, while Simpson Dura-Vent's sales increased 5.6%. Homecenters were 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 rates in sales with the addition of powder actuated tools contributing significantly. Strong-Wall sales declined during the third quarter of 2001 as compared to the third quarter of 2000. Sales of Simpson Dura-Vent's chimney and pellet vent product lines increased compared to the third quarter of 2000 while sales of its Direct-Vent products decreased.

Income from operations increased 6.9% from $18,558,291 in the third quarter of 2000 to $19,839,692 in the third quarter of 2001 and gross margins decreased from 40.6% in the third quarter of 2000 to 38.3% in the third quarter of 2001. The decrease in gross margin was primarily due to the lower margins at BMF. The acquisition of BMF also contributed to the increase in operating expenses. Selling expenses increased 6.3% from $9,806,039 in the third quarter of 2000 to $10,423,311 in the third quarter of 2001, primarily due to higher personnel costs related to the increase in the number of sales and merchandising personnel, including those associated with the Anchoring Systems product line. General and administrative expenses decreased 1.4% from $12,655,445 in the third quarter of 2000 to $12,477,597 in the third quarter of 2001. This decrease was primarily due to a decrease in cash profit sharing, partially offset by increased administrative costs, including those associated with the acquisition of BMF. The tax rate was 40.4% in the third quarter of 2001, a decrease from 41.2% in the third quarter of 2000.

For the first nine months of 2001, most of the overall sales growth occurred in California and in Europe as a result of the acquisition of BMF. Simpson Strong-Tie's first nine months' sales increased 15.4% over the same period last year, while Simpson Dura-Vent's sales increased 4.7%. Homecenters and contractor distributors were the fastest growing Simpson Strong-Tie connector sales channels. 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 strong year to date growth over the first nine months of 2000 as a result of the increased sales during the first half of 2001. Sales of Simpson Dura-Vent's chimney and pellet vent product lines increased compared to the first nine months of 2000 while sales of its Direct-Vent products decreased.

Income from operations increased 7.9% from $51,177,217 in the first nine months of 2000 to $55,216,453 in the first nine months of 2001 and gross margins decreased from 40.3% in the first nine months of 2000 to 38.9% in the first nine months of 2001. The decrease in gross margin was primarily due to the lower margins at BMF. The acquisition of BMF also contributed to the increases in operating expenses. Selling expenses increased 11.7% from $28,087,648 in the first nine months of 2000 to $31,375,353 in the first nine months of 2001. The increase was primarily due to higher personnel costs related to the increase in the number of sales and merchandising personnel, including those associated with the Anchoring Systems product line, as well as increased promotional expenses. General and administrative expenses increased 10.9% from $34,950,828 in the first nine months of 2000 to $38,746,495 in the first nine months of 2001. This increase was due in part to a non-cash charge to write-off the remaining Keybuilder.com software license in the second quarter of 2001, additional administrative personnel and higher costs associated with the acquisitions of BMF, Anchor Tiedown Systems and Masterset Fastening Systems, Inc. Partially offsetting this increase was a decrease in cash profit sharing. The tax rate was 41.5% in the first nine months of 2001, an increase from 41.0% in the first nine months of 2000.

In August 2001, the German subsidiary of BMF purchased the remaining 51% stake in Bulldog-Simpson GmbH for approximately $600,000 in cash.

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 decrease in previously reported retained earnings of $588,455 as of September 30, 2000, and 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 nine months ended September 30, 2001, was immaterial.
