FOR IMMEDIATE RELEASE

Ducommun Reports Results for the

Fourth Quarter and Year Ended December 31, 2011

Posts Record Backlog of $636 Million; LaBarge Integration Effectively Complete

LOS ANGELES, California (March 5, 2012) — Ducommun Incorporated (NYSE:DCO) today reported results for its fourth quarter and twelve months ended December 31, 2011.

Highlights

“Ducommun ended 2011 much stronger and better positioned than when the year began, with our operations bolstered by the addition of LaBarge,” said Anthony J. Reardon, president and chief executive officer. “The integration of our two organizations is now effectively complete. We have reduced corporate overhead, and our staffs are working together seamlessly to improve and grow the new Ducommun. Our backlog stands at a record $636 million, and the legacy LaBarge business is providing many new growth avenues, offsetting some weakness in a few of our legacy military applications. At the same time, Ducommun AeroStructures continues to show top-line expansion — driven by robust commercial aerospace demand. With our focus on margins, all factors are coming together for improved performance in 2012.”

Fourth Quarter Results

Sales for the fourth quarter of 2011 increased 85% to $188.2 million, compared with $101.8 million for the fourth quarter of 2010, reflecting $90.6 million in revenue from the acquisition of LaBarge. The Company reported a net loss of $48.5 million, or $(4.60) per fully diluted share, compared with net income of $4.2 million, or $0.39 per fully diluted share, for the comparable period last year. Excluding pre-tax acquisition-related expenses (including cost of sales related to the write-up of LaBarge inventory) of $3.2 million and a pre-tax non-cash goodwill impairment charge of $54.3 million, net income for the fourth quarter of 2011 was $2.8 million, or $0.27 per fully diluted share. The $54.3 million goodwill impairment charge was related to the Company’s Ducommun LaBarge Technologies subsidiary and was driven by a decline in the Company’s market value as of December 31, 2011, following the LaBarge acquisition and a softening defense market. The non-cash charge does not impact the Company’s ongoing business operations nor does it affect liquidity, cash flow from operations or financial covenant compliance for any of the Company’s outstanding debt.

During the quarter, the Company generated $27.9 million of cash flow from operations, excluding $2.0 million of transaction-related costs.

Ducommun AeroStructures (DAS)

The DAS segment reported net sales for the fourth quarter of $68.9 million compared with $65.6 million in the prior-year period, representing an increase of 5%. The higher revenues were primarily the result of increased shipments of commercial aerospace products. Operating income for the 2011 fourth quarter was $3.4 million, or 4.9% of revenues, compared with $5.4 million, or 8.2% of revenues, for the prior-year period. The lower operating results were primarily due to start-up costs associated with new programs. These costs negatively impacted operating margins by $3.0 million, or 5.1 percentage points, on revenues of $4.9 million in the 2011 fourth quarter, compared with an impact of $1.3 million, or 2.4 percentage points, on revenues of $2.5 million in the comparable period of 2010.

Ducommun LaBarge Technologies (DLT)

The DLT segment reported net sales for the fourth quarter of $119.4 million compared with $36.2 million in the fourth quarter of 2010. The reason for the substantial increase in revenues was $90.6 million of contribution from LaBarge, covering a broad set of industrial and commercial end markets, partially offset by lower revenues tied to the Company’s engineering services business and delayed orders for F-15 and F-18 radar products. Operating loss for the fourth quarter of 2011 was $45.5 million, compared with operating income of $4.2 million in the 2010 fourth quarter. Excluding acquisition-related expenses (including cost of sales related to the write-up of LaBarge inventory) of $2.5 million and goodwill impairment charges of $54.3 million, DLT’s operating income was $11.3 million, or 9.5% of revenues, as compared with $4.2 million, or 11.7% of revenues, in the prior year period.

Corporate General and Administrative Expenses (CG&A)

CG&A expenses for the fourth quarter 2011 were $3.3 million, as compared with $5.3 million in the 2010 fourth quarter. Excluding acquisition-related expenses of $0.6 million, CG&A was $2.7 million, or 1.4% of sales, as compared with $5.3 million, or 5.2% of sales, in the prior year period.

Full Year Results

Sales for the twelve months of 2011 increased 42% to $580.9 million, compared with $408.4 million in 2010, reflecting revenue of $175.4 million from the LaBarge acquisition. The Company posted a net loss in 2011 of $47.6 million, or $(4.52) per fully diluted share, compared with net income of $19.8 million, or $1.87 per fully diluted share, in 2010. Excluding pre-tax acquisition-related expenses (including cost of sales related to the write-up of LaBarge inventory) of $18.5 million and a pre-tax non-cash goodwill impairment charge of $54.3 million, net income was $14.9 million, or $1.40 per fully diluted share. In 2011, the Company generated $22.6 million of cash flow from operations, excluding $25.6 million of acquisition-related costs.

Ducommun AeroStructures (DAS)

The DAS segment reported net sales for the twelve months of 2011 of $292.8 million, compared with $271.6 million in 2010, an increase of 8%. The higher revenues were primarily the result of increased shipments of commercial aerospace products. Operating income in 2011 was $25.8 million, or 8.8% of revenues, compared with $28.7 million, or 10.6% of revenues, in the prior year period. The lower operating results were primarily due to start-up costs for new programs. These costs negatively impacted operating margins by $8.8 million, or 4.0 percentage points, on revenues of $21.6 million in 2011, compared with an impact of $4.6 million, or 2.1 percentage points, on revenues of $9.4 million in 2010.

Ducommun LaBarge Technologies (DLT)

The DLT segment reported net sales for the twelve months of 2011 of $288.2 million compared with $136.8 million in 2010. The primary reason for the increase in revenues was $175.4 million of contribution from LaBarge representing a broad set of industrial and commercial end markets, partially offset by lower revenues for engineering services and certain legacy Ducommun manufactured technology products. Operating loss in 2011 was $33.4 million compared with operating income of $13.2 million in 2010. Excluding acquisition-related expenses (including cost of sales related to the write-up of LaBarge inventory) and pre-tax non-cash goodwill impairment charges, DLT’s operating income was $27.0 million, or 9.4% of revenues, as compared with $13.2 million, or 9.6% of revenues, in 2010.

Corporate General and Administrative Expenses (CG&A)

CG&A expenses in 2011 were $26.5 million, compared with $15.4 million in 2010. Excluding acquisition-related expenses of $12.4 million, CG&A was $14.1 million, or 2.4% of sales, in 2011, as compared with $15.4 million, or 3.8% of sales, in 2010.

“While we still have work to do, particularly with regard to improving margins, we feel very confident about the future given the strengths of a more capable and multifaceted Ducommun,” Mr. Reardon continued. “We now have additional talent to deploy, more technical and manufacturing expertise to provide, and a broader base of customers with which to partner. We knew that the last half of 2011 would present some challenges, but we did an excellent job integrating DLT and had solid operating performance within that segment as a result. Furthermore, we won and began development on 14 new aerostructure programs last year, and, while these startup contracts adversely impacted 2011 performance, we believe that investing in such programs and customers will help drive higher revenue and profit margins over the long term. Our immediate goal is to continue to generate solid cash flow, retire debt and reduce our leverage. Some challenges surely remain as we drive to improve operating results, but the outlook is bright for Ducommun.”
