News Release

LOS ANGELES, California (July 31, 2006) -- Ducommun Incorporated (NYSE: DCO) today reported results for its second quarter ended July 1, 2006.

Sales for the second quarter of 2006 were $77.5 million, compared to $62.0 million for the second quarter of 2005. Net income for the second quarter of 2006 was $3.2 million, or $0.31 per diluted share, compared to net income of $4.1 million, or $0.40 per diluted share, for the same period last year.

Sales for the second quarter of 2006 increased 25% from the same period last year primarily due to the acquisition of Miltec Corporation (Miltec) on January 6, 2006 and higher sales at Ducommun AeroStructures. The Company’s mix of business in the second quarter of 2006 was approximately 67% military, 32% commercial and 1% space, compared to 63% military, 33% commercial and 4% space in the second quarter of 2005.

Gross profit, as a percentage of sales, decreased to 19.7% in the second quarter of 2006 from 22.8% in the second quarter of 2005. The decrease in gross profit margin was primarily attributable to a decline in operating performance at Ducommun Technologies, which included an $860,000 increase in inventory reserves related to a canceled contract, partially offset by an improvement in operating performance at Ducommun AeroStructures.

Selling, general and administrative (SG&A) expenses, as a percentage of sales, decreased to 12.4% in the second quarter of 2006 from 12.5% in the second quarter of 2005. Period to period SG&A expenses increased as a result of: • The acquisition of Miltec, which has higher SG&A expenses as a percentage of sales than Ducommun had prior to the acquisition, • Non-cash amortization of intangibles of $317,000 in the second quarter of 2006 related to the Miltec acquisition, and • Non-cash stock option expense of $412,000 related to the adoption of SFAS 123(R) “Share Based Payment” on January 1, 2006. Net income for the second quarter of 2006 decreased 22% from the second quarter of 2005 primarily for the reasons described above. It also declined due to higher interest expense resulting from the acquisitions of Miltec and WiseWave (completed in May 2006).

Sales for the first six months of 2006 were $149.6 million, compared to $125.8 million for the first six months of 2005. Net income for the first six months of 2006 was $5.9 million, or $0.58 per diluted share, compared to net income of $8.2 million, or $0.80 per diluted share, for the same period last year.

Sales for the first six months of 2006 increased 19% from the same period last year primarily due to the acquisition of Miltec and higher sales at Ducommun AeroStructures. The Company’s mix of business in the first six months of 2006 was approximately 67% military, 32% commercial and 1% space, compared to 62% military, 35% commercial and 3% space in the first six months of 2005.

Gross profit, as a percentage of sales, decreased to 19.9% in the first six months of 2006 from 20.4% in the first six months of 2005. The decrease in gross profit margin was primarily attributable to a decline in operating performance at Ducommun Technologies, which included an $860,000 increase in inventory reserves related to a canceled contract, partially offset by an improvement in operating performance at Ducommun AeroStructures.

SG&A expenses, as a percentage of sales, increased to 12.9% in the first six months of 2006 from 11.6% in the first six months of 2005. The increase in SG&A expenses, and as a percentage of sales, was primarily due to: • The acquisition of Miltec, which has higher SG&A expenses as a percentage of sales than Ducommun had prior to the acquisition, • Non-cash amortization of intangibles of $633,000 in the first six months of 2006 related to the Miltec acquisition, and • Non-cash stock option expense of $782,000 related to the adoption of SFAS 123(R) “Share Based Payment” on January 1, 2006. Net income for the first six months of 2006 decreased 27% from the first six months of 2005 for the reasons described above. It also declined due to higher interest expense resulting from the acquisitions of Miltec and WiseWave and an increase in the Company’s effective tax rate. The Company’s effective tax rate in the first six months of 2006 was 36.5%, compared to 25.9% in the first six months of 2005. The effective tax rate in the first six months of 2005 benefited from reductions in income tax reserves established in prior periods as well as research and development tax credits. Joseph C. Berenato, chairman, president and chief executive officer, stated, “The aerospace marketplace remains healthy, with growing opportunities in commercial aerospace and a steady rate of spending from the Department of Defense (DOD) budget. We are seeing some tightening of military spending, however, as DOD budgets are being stretched by Iraq-related expenditures. We are integrating our Miltec and WiseWave acquisitions, launching our new Thailand manufacturing facility and driving Lean and Six Sigma deeper into our businesses. While we expect 2006 to be a year of new program investment, integration and consolidation of facilities and developing broader capabilities to take advantage of the opportunities available to us over the rest of this decade, we continue to look for complementary acquisitions to augment our internal growth activities.”

Founded in 1849, Ducommun Incorporated provides engineering and manufacturing services to the aerospace and defense industry.
