Ducommun Incorporated News Release

Net income for the fourth quarter of 2006 increased 21.2% from the fourth quarter of 2005. Interest expense was higher in the fourth quarter of 2006 due to debt incurred from the acquisitions of Miltec, WiseWave and CMP. Net income was favorably impacted by income tax benefits and tax reserves related to research and development tax credits. The Company’s effective tax rate for the fourth quarter of 2006 was a tax benefit of 48.3%, compared to an effective tax rate of 16.5% in the fourth quarter of 2005.

Sales for the year 2006 increased 27.8% from the same period in 2005, primarily due to the acquisitions of Miltec, WiseWave and CMP, as well as internal growth at DAS. The Company’s mix of business for 2006 was 66% military, 32% commercial and 2% space, compared to 61% military, 35% commercial and 4% space for the year 2005.

Gross profit, as a percentage of sales, decreased to 19.6% in the year 2006 from 20.7% for the year 2005. The gross profit margin decrease was primarily attributable to the reasons discussed above with respect to the fourth quarter, as well as an $860,000 increase in inventory reserves in the second quarter of 2006 related to a canceled contract.

Selling, general and administrative (SG&A) expenses, as a percentage of sales, increased to 13.1% for the year 2006 from 12.4% for the year 2005. The increase in SG&A expenses as a percentage of sales, was primarily the result of:

Joseph C. Berenato, chairman, president and chief executive officer, stated, “2006 was a busy year for Ducommun as we continued to position the Company for growth. With the changes we are making to improve our technological and operational capabilities and the fact that both the commercial and military aerospace markets remain positive, we believe we are well positioned to drive our key goals of One Company, Operational Excellence and Profitable Growth. Strong cash flow during 2006 allowed us to reduce our Total Debt to Total Capital ratio to 14%, well below our target of 30%. Therefore, we will continue to augment our internal growth activities with acquisitions which are complementary to our existing businesses.”

Mr. Berenato continued, “I want to thank all of our Ducommun Team Members for their performance and effort throughout 2006. We accomplished quite a bit last year by acquiring three businesses to strengthen DTI, consolidating facilities, starting up our first international operation, and extending our five largest contracts at DAS. I look forward to our building on these accomplishments in 2007.”
