News Release

LOS ANGELES, California (May 4, 2006) -- Ducommun Incorporated (NYSE: DCO) today reported results for its first quarter ended April 1, 2006.

Sales for the first quarter of 2006 were $72.2 million, compared to $63.8 million for the first quarter of 2005. Net income for the first quarter of 2006 was $2.8 million, or $0.27 per diluted share, compared to net income of $4.1 million, or $0.40 per diluted share, for the comparable period last year.

Sales for the first quarter of 2005 increased 13% from the same period last year primarily due to the acquisition of Miltec Corporation (Miltec) on January 6, 2006. The Company’s mix of business in the first quarter of 2006 was approximately 67% military, 32% commercial and 1% space, compared to 61% military, 36% commercial and 3% space in the first quarter of 2005.

Gross profit, as a percentage of sales, increased to 20.1% in the first quarter of 2006 from 18.2% in the first quarter of 2005. The increase in gross profit margin was primarily attributable to improvements in operating performance at Ducommun AeroStructures.

Selling, general and administrative (SG&A) expenses, as a percentage of sales, increased to 12.8% in the first quarter of 2006 from 10.8% in the first quarter of 2005. The increase in SG&A expenses, as a percent of sales, was primarily due to:

• The acquisition of Miltec, which has higher SG&A expenses as a percent of sales than Ducommun had prior to the acquisition, and
• Non-cash amortization of intangibles of $316,000 in 2006 related to the Miltec acquisition.

The first quarter of 2006 also included non-cash stock option expense of $370,000 related to the adoption of SFAS123(R) “Share Based Payment” on January 1, 2006.

Net income for the first quarter of 2006 decreased 32% from the first quarter of 2005 primarily due to an increase in the Company’s effective tax rate. The Company’s effective tax rate in the first quarter of 2006 was 36.7%, compared to 12.2% in the first quarter of 2005. The effective tax rate in the first quarter of 2005 benefited from reductions in income tax reserves established in prior periods and research and development tax credits.

Joseph C. Berenato, chairman, president and chief executive officer, stated, “Excluding the stock option expense, our pre-tax income was higher in this year’s first quarter than in last year’s first quarter. As we continue to drive Lean and Six Sigma training across our existing businesses, we are beginning to see financial improvement at some of our operations. In addition, we anticipate that Miltec will open broad, engineering-oriented opportunities to us. As we begin the process of integrating Miltec, we are continuing to seek complementary acquisitions. As stated in our Annual Report, we expect 2006 to be a year of investment in new programs, in integration and consolidation of facilities, and in developing broader capabilities to take advantage of the opportunities available to us over the next 4-5 years.”

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