LOS ANGELES, California (July 30, 2007) -- Ducommun Incorporated (NYSE: DCO) today reported results for its second quarter ended June 30, 2007.

Sales for the second quarter of 2007 were $91.1 million, compared to $77.5 million for the second quarter of 2006. Net income for the second quarter of 2007 was $4.6 million, or $0.44 per diluted share, compared to net income of $3.2 million, or $0.31 per diluted share, for the same period last year.

Sales for the second quarter of 2007 increased 18% from the same period last year primarily due to a strong increase in commercial sales. The Company’s mix of business in the second quarter of 2007 was approximately 61% military, 37% commercial and 2% space, compared to 67% military, 32% commercial and 1% space in the second quarter of 2006.

Gross profit, as a percentage of sales, increased to 21.7% in the second quarter of 2007 from 19.7% in the second quarter of 2006. Selling, general and administrative (SG&A) expenses, as a percentage of sales, increased to 13.3% in the second quarter of 2007 from 12.4% in the second quarter of 2006. The increase in SG&A expenses, as a percentage of sales, was primarily the result of higher bonus accruals in 2007 and the expenses of the CMP business which was acquired in the third quarter of 2006.

Net income for the second quarter of 2007 increased 44% from the second quarter of 2006 primarily due to the reasons stated above and a lower effective tax rate, partially offset by higher interest expense in the second quarter of 2007.

Sales for the first six months of 2007 were $179.2 million, compared to $149.6 million for the first six months of 2006.
