FOR IMMEDIATE RELEASE

DUCOMMUN INCORPORATED REPORTS RESULTS

FOR THE FIRST QUARTER 2004

LOS ANGELES, California (May 10, 2004) – Ducommun Incorporated (NYSE: DCO) today reported results for the first quarter ended April 3, 2004.

Sales for the first quarter of 2004 were $58.2 million, compared to $55.0 million for the first quarter of 2003. Net income for the first quarter of 2004 was $2.2 million, or $0.22 per diluted share, compared to net income of $3.1 million, or $0.31 per diluted share, for the comparable period last year.

The increase in sales in the first quarter of 2004, from the same period last year, included approximately $1.3 million in sales from the August 2003 acquisition of DBP Microwave. The Company’s mix of business in the first quarter of 2004 was approximately 61% military, 35% commercial and 4% space, compared to 65% military, 31% commercial and 4% space in the first quarter of 2003.

Gross profit, as a percentage of sales, decreased to 17.9% in the first quarter of 2004 from 21.8% in the first quarter of 2003. This decrease was primarily the result of initial losses on several new contracts at Ducommun AeroStructures during the first quarter of 2004, partially offset by the impact of spreading fixed overhead costs over a greater sales volume. The decline in gross profit margins also included a provision of $1,894,000 established during the first quarter of 2004 for estimated cost overruns on certain of the new contracts at Ducommun AeroStructures.

Joseph C. Berenato, chairman and chief executive officer, commented, “Our performance in the first quarter was disappointing. But despite the shortfall created by several program start-ups, our operations continue to improve and are performing well. DBP Microwave which was acquired in August 2003 has exceeded our expectations. Furthermore, we are beginning to realize the benefits of streamlined operations as we shed more overhead and capture process efficiencies at both Ducommun AeroStructures and Ducommun Technologies.

I am confident that we have taken appropriate action to address the problems that hurt us in the first quarter. These measures combined with the continuous improvement that we are seeing in other areas should result in significantly better performance during the rest of the year.”

Mr. Berenato continued, “Our goals remain unchanged: secure prominent positions on higher level subsystem and subassembly programs, reduce our cost structure, and acquire compatible businesses for Ducommun Technologies. If successful in achieving these objectives, we will strengthen our competitive position and, in turn, our ability to consistently deliver value to our shareholders.”

Founded in 1849, Ducommun Incorporated manufactures components and assemblies for the aerospace industry.
