LOS ANGELES, California (February 22, 2010) — Ducommun Incorporated (NYSE:DCO) today reported results for its fourth quarter and year ended December 31, 2009.

Highlights

Fourth Quarter Results

Sales for the fourth quarter of 2009 increased 4% to $105.7 million from $101.4 million for the fourth quarter of 2008. Ducommun had a net loss in the fourth quarter of 2009 of $3.2 million, or ($0.30) per diluted share, compared to a net loss of $4.2 million, or ($0.40) per diluted share, in the prior year period. Net income was impacted by a non-cash, after-tax charge of $7.8 million, or $0.74 per diluted share, in the fourth quarter of 2009, and $8.0 million, or $0.76 per diluted share, in the fourth quarter of 2008.

“We continued to take the necessary steps this quarter to position the Company for an eventual rebound in our end markets,” said Anthony J. Reardon, president and chief executive officer. “Excluding the goodwill impairment charge, our operating performance reflected Ducommun’s strong breadth of programs and lean manufacturing initiatives. Our ability to manage the Company’s cost structure even at lower output levels has helped Ducommun navigate through a difficult demand environment, while generating solid cash flow. Ducommun’s platforms and customer relationships are our biggest strategic

asset, which we are leveraging to pursue – and win – the commercial and military contracts that will drive future growth.”

The 4% increase in revenue for the fourth quarter of 2009 was due to the Company’s acquisition of DynaBil Industries, Inc. (DAS-NY), partially offset by lower year-over-year sales for the Apache helicopter and regional and business aircraft. DAS-NY contributed approximately $9.8 million in fourth quarter 2009 revenue, compared to $0.9 million for the fourth quarter of 2008. The Company’s mix of business in the fourth quarter of 2009 was approximately 62% military, 36% commercial and 2% space, compared to 63% military, 35% commercial and 2% space in the fourth quarter of 2008.

Gross profit, as a percentage of sales, was 18.2% in the fourth quarter of 2009, in line with the fourth quarter of 2008. The fourth quarter 2009 gross profit was negatively impacted by a $0.7 million reserve for sales tax liability on past tooling sales.

Selling, general and administration (SG&A) expenses decreased to $12.0 million, or 11.4% of sales, in the fourth quarter of 2009, compared to $14.6 million, or 14.4% of sales, in the fourth quarter of 2008. The decrease in SG&A resulted principally from a $2.2 million reduction in environmental reserves established in prior years and corporate-wide cost control initiatives, partially offset by a full quarter of SG&A expense from the acquisition of DAS-NY and an increase in amortization of intangible assets of $0.7 million, again related to the acquisition of DAS-NY.

The pre-tax non-cash goodwill impairment charge of $12.9 million recorded during the fourth quarter of 2009 related to the Company’s Miltec subsidiary and resulted from management’s reassessment of the future prospects of this business in view of a reduction in the U.S. government’s budgetary forecast and funding levels in military markets. Because the majority of Miltec’s business is U.S. government related, the multi-year forecast of Miltec’s sales and cash flow from operations was reduced, resulting in an unfavorable impact on the unit’s fair market value assessment. During the fourth quarter of 2008, the Company also recorded a pre-tax non-cash goodwill impairment charge relating to Miltec in the amount of $13.1 million.

The Company’s net loss for the fourth quarter of 2009 decreased from the fourth quarter of 2008 primarily due to the reasons stated above. The fourth quarter included an effective tax benefit of 49%, compared to a tax benefit of 55% for the fourth quarter of 2008.

Full Year Results

Revenue for the full year 2009 rose 7% to $430.7 million from $403.8 million for the year 2008. Net income for 2009 was $10.2 million, or $0.97 per diluted share, compared to net income of $13.1 million, or $1.23 per diluted share, in 2008. Net income prior to the goodwill impairment charges was $1.71 and $1.99 per diluted share in 2009 and 2008, respectively.

The 7% revenue increase in 2009 was due to the Company’s acquisition of DAS-NY, partially offset by lower year-over-year sales for the Apache helicopter and regional and business aircraft. DAS-NY contributed approximately $42.1 million in revenue during 2009, compared to $0.9 million in 2008. The Company’s mix of business for 2009 was approximately 62% military, 36% commercial and 2% space, compared to 59% military, 39% commercial and 2% space for the year 2008.

Gross profit, as a percentage of sales, decreased to 18.3% in 2009 from 20.3% in 2008. The Company’s gross profit margin in 2009 was negatively impacted by inventory valuation adjustments and sales tax reserves of $5.8 million.

Selling, general and administration (SG&A) expenses decreased to $49.6 million, or 11.5% of sales, for 2009, compared to $50.5 million, or 12.5% of sales, for 2008. The decline in SG&A resulted principally from a $2.2 million reduction in environmental reserves established in prior years along with corporate-wide cost control initiatives, partially offset by a full year of SG&A expense from the acquisition of DAS-NY and an increase in amortization of intangible assets of $1.5 million, again related to the acquisition of DAS-NY.

Net income for 2009 decreased 22% from 2008 primarily due to the reasons stated above and higher interest expense on higher debt levels. The Company’s effective tax rate for 2009 was 26.0%, compared to 23.1% for 2008.

Mr. Reardon concluded, “As we begin 2010, we continue to have an enviable position on key commercial and military programs, a solid backlog, and a strong balance sheet, with significant cash flow generation due to effective working capital management. We remain committed to improving Ducommun’s financial results even as we navigate through some near-term uncertainty. Given our resources and liquidity to fund future growth, we are optimistic about the future.”
