PART I

GENERAL

Ducommun (“we”, “our”, or “the Company”) provides engineering and manufacturing services primarily to the aerospace and defense industry through a wide spectrum of electronic and structural applications. We design, engineer and manufacture a broad range of electronics, electromechanical and interconnect systems and components, mission-critical aerostructure and critical components and subassemblies. We also provide engineering, technical and program management services. Our products and services are used on domestic and foreign commercial and military aircraft, helicopter, missile and space programs, as well as in certain industrial, natural resources, medical and other commercial markets. We operate through two primary business units: Ducommun LaBarge Technologies (“DLT”) and Ducommun AeroStructures (“DAS”). We are the successor to a business that was founded in California in 1849 and reincorporated in Delaware in 1970.

On June 28, 2011, the Company completed the acquisition of all the outstanding stock of LaBarge, Inc. (“LaBarge”), a publicly-owned company based in St. Louis, Missouri for $325,315,000 (net of cash acquired and excluding acquisition costs). LaBarge was a provider of electronics manufacturing services to aerospace, defense and other diverse markets. LaBarge provided its customers with sophisticated electronic, electromechanical and mechanical products through contract design and manufacturing. The acquisition was funded from internally generated cash, senior unsecured notes and a senior secured term loan. The operating results for this acquisition have been included in the consolidated statements of operations since the date of acquisition. For the twelve months ended December 31, 2011, operating expenses included expenses related to the acquisition of LaBarge of $16,137,000 and interest expense included the write-off of $831,000 of unamortized financing costs, as a result of the Company’s debt refinancing related to the acquisition of LaBarge.

PRODUCTS AND SERVICES

We now operate in two business segments, Ducommun LaBarge Technologies and Ducommun AeroStructures, each of which is a reportable operating segment.

Business Segment Information

We operate and report our financial performance based on the following two reportable segments: Ducommun Aerostructures (“DAS”) and Ducommun LaBarge Technologies (“DLT”). The results of operations among our operating segments vary due to differences in competitors, customers, extent of proprietary deliverables and performance.

DAS engineers and manufactures aerospace structural components and subassemblies. DLT was formed in June 2011 by the combination of our former Ducommun Technologies segment (“DTI”) and LaBarge. DLT designs, engineers and manufactures a broad range of electronic, electromechanical and interconnect systems and components. In addition, DLT provides technical and program management services (including design, development, and integration and testing of prototype products) principally for advanced weapons and missile defense systems.

Ducommun LaBarge Technologies (DLT)

DLT designs, engineers and manufactures a broad range of electronics, electromechanical and interconnect systems and components. Our product offerings include cable assemblies, wiring harness and interconnect systems, printed circuit board assemblies and mechanical and electromechanical subassemblies, illuminated pushbutton switches and panels, microwave and millimeter switches and filters and fractional horsepower motors and resolvers. In addition we provide engineering, technical and program management services to support our product offerings. Components and assemblies are provided principally for domestic and foreign commercial and military aircraft, helicopter and space programs as well as selected non-aerospace applications principally for the industrial, natural resources and medical industries. Engineering, technical and program management services (including design, development, and integration and testing of Prototype Products) are provided principally for advanced weapons and missile defense systems.

Electromechanical Subassemblies and Interconnect Systems

DLT designs, engineers and manufactures electromechanical subassemblies and interconnect systems for the defense electronics and commercial aircraft markets and for other commercial uses such as industrial automation, satellites, space launch vehicles, oil wells, mine automation equipment and medical devices. DLT builds custom, high performance electronics, electromechanical and interconnect systems and our products include sophisticated radar enclosures, aircraft avionics racks and shipboard communications and control enclosures, printed circuit board assemblies, cable assemblies, wire harnesses, interconnect systems and other high level complex assemblies. DLT has a fully integrated manufacturing capability, including manufacturing, engineering, fabrication, machining, assembly, electronic integration and related processes.

Table of Contents

Panels, Switches and Related Components

DLT designs, engineers and manufactures illuminated switches, switch assemblies, keyboard panels, and edge lit panels, used in many military and commercial aircraft, helicopter, and space programs. DLT manufactures switches and panels where high reliability is a prerequisite. DLT also designs, engineers and manufactures microwave and millimeterwave switches, filters, and other components used principally on commercial and military aircraft and satellites. In addition, DLT develops, designs and manufactures high precision actuators, stepper motors, fractional horsepower motors and resolvers principally for space and oil service applications, and microwave and millimeterwave products for certain non-aerospace applications.

Engineering, Technical and Program Management Services

DLT provides missile and aerospace systems design, development, integration and testing. Engineering, technical and program management services are provided principally for advanced weapons systems and missile defense primarily for United States defense, space and homeland security programs.

Ducommun AeroStructures (DAS)

DAS provides aluminum stretch-forming, titanium and aluminum hot-forming, machining, composite lay-up, metal bonding, and chemical milling services principally for domestic and foreign commercial and military aircraft, helicopter and space programs.

Stretch-Forming, Hot-Forming and Machining

DAS supplies the aerospace industry with engineering and manufacturing of complex components using stretch-forming and hot-forming processes and computer-controlled machining. Stretch-forming is a process for manufacturing large, complex structural shapes primarily from aluminum sheet metal extrusions. DAS has some of the largest and most sophisticated stretch-forming presses in the United States. Hot-forming is a metal working process conducted at high temperature for manufacturing close-tolerance titanium and aluminum components. DAS designs and manufactures the tooling required for the production of parts in these forming processes. Certain components manufactured by DAS are machined with precision milling equipment, including three 5-axis gantry profile milling machines and seven 5-axis numerically-controlled routers to provide computer-controlled machining and inspection of complex parts up to 100 feet long.

Composites and Metal Bonding

DAS engineers and manufactures metal, fiberglass and carbon composite aerostructures. DAS produces helicopter main and tail rotor blades, and adhesive bonded assemblies, including spoilers, winglets, and fuselage structural panels for aircraft.

Chemical Milling

DAS is a major supplier of close tolerance chemical milling services for the aerospace industry. Chemical milling removes material in specific patterns to reduce weight in areas where full material thickness is not required. This sophisticated etching process enables DAS to produce lightweight, high-strength designs that would be impractical to produce by conventional means. DAS offers production-scale chemical milling on aluminum, titanium, steel, nickel-base and super alloys. Jet engine components, wing leading edges and fuselage skins are examples of products that require chemical milling.

SALES AND MARKETING

Military components manufactured by us are employed in many of the country’s front-line fighters, bombers, helicopters and support aircraft, as well as land and sea-based applications. Engineering, technical and program management services are provided principally for United States defense, space and homeland security programs. Our defense business is diversified among a number of military manufacturers and programs. In the space sector, we continue to support various unmanned launch vehicle and satellite programs.

Our commercial sales depend substantially on aircraft manufacturers’ production rates, which in turn depend on deliveries of new aircraft. Deliveries of new aircraft by aircraft manufacturers are dependent on the financial capacity of the airlines and leasing companies to purchase the aircraft. Sales of commercial aircraft could be affected as a result of changes in new aircraft orders, or the cancellation or deferral by airlines of purchases of ordered aircraft. Our sales for commercial aircraft programs also could be affected by changes in our customers’ inventory levels and changes in our customers’ aircraft production build rates.

Our sales into the industrial medical, natural resources and other commercial markets are customer focused in the various markets and driven primarily by manufacturing outsourcing requirements. For example our production rates in the mining down hole drilling market are driven by the number of oil rigs operating in North America.

Sales related to military and space, commercial aerospace, and other end markets were approximately 52%, 32% and 16%, respectively, of total sales in 2011. We believe the diversity of LaBarge’s customer base will help to reduce the impact to us of volatility in any one market sector.

Many of our contracts are fixed price contracts subject to termination at the convenience of the customer (as well as for default). In the event of termination for convenience, the customer generally is required to pay the costs we incurred and certain other fees through the date of termination. Larger, long-term government subcontracts may have provisions for milestone payments, progress payments or cash advances for purchase of inventory.

Table of Contents

We seek to develop strong, long-term relationships with our customers, which provide the basis for future sales. These close relationships allow us to better understand each customer’s business needs and identify ways to provide greater value to the customer.

MAJOR CUSTOMERS

The Company had substantial sales to Boeing, Raytheon, United Technologies, Spirit AeroSystems and Owen-Illinois. During 2011, sales to Boeing were $112,071,000, or approximately 19.3% of total sales; sales to Raytheon were $50,567,000 or approximately 8.7% of total sales; sales to United Technologies were $29,830,000 of total sales, or approximately 5.1% of total sales; sales to Spirit AeroSystems were $28,590,000 or approximately 4.9% and sales to Owen-Illinois were $22,796,000, or approximately 3.9% of total sales. Sales to Boeing, Raytheon, United Technologies, Spirit AeroSystems and Owens-Illinois are diversified over a number of different programs and applications.

INFORMATION ABOUT FOREIGN AND DOMESTIC OPERATIONS AND EXPORT SALES

In 2011, 2010, and 2009, sales to foreign customers worldwide were $50,865,000, $37,970,000, and $32,121,000, respectively. The Company has manufacturing facilities in Thailand and Mexico. The amounts of revenue, profitability and identifiable assets attributable to foreign sales activity were not material when compared with the revenue, profitability and identifiable assets attributed to United States domestic operations during 2011, 2010 and 2009. The Company had no sales to a foreign country greater than 3% of total sales in 2011, 2010 and 2009. The Company is not subject to any significant foreign currency risks since all sales are made in United States dollars.

RESEARCH AND DEVELOPMENT

The Company performs concurrent engineering with its customers and product development activities under Company-funded programs and under contracts with others. Concurrent engineering and product development activities are performed for commercial, military and space applications. The Company also performs high technology systems engineering and analysis, principally under customer-funded contracts, with a focus on sensors system simulation, engineering and integration.

RAW MATERIALS AND COMPONENTS

Raw materials and components used in the manufacture of our products, include aluminum, titanium, steel and carbon fibers, as well as a wide variety of electronic interconnect and circuit card assemblies and components. These raw materials are generally available from a number of vendors and are generally in adequate supply. However, we, from time to time, have experienced increases in lead times for and deterioration in availability of, aluminum, titanium and certain other materials. Moreover, certain components, supplies and raw materials for our operations are purchased from single sources. In such instances, we strive to develop alternative sources and design modifications to minimize the potential for business interruptions.

COMPETITION

The markets we serve are highly competitive, and our products and services are affected by varying degrees of competition. We compete worldwide with domestic and international companies in most markets, some of which are substantially larger and have greater financial, sales, technical and personnel resources. Larger competitors offering a wider array of products and services than those offered by us could have a competitive advantage by offering potential customers bundled products and services that we cannot match. In addition, our customers may, in fact, have the ability to produce internally the products contracted to us, but because of cost, capacity, engineering capability or other reasons, outsource production of such products to us. Our ability to compete depends principally upon the quality of our goods and services, competitive pricing, product performance, design and engineering capabilities, new product innovation and the ability to solve specific customer problems.

PATENTS AND LICENSES

We have several patents, but we do not believe that our operations are dependent upon any single patent or group of patents. In general, we rely on technical superiority, continual product improvement, exclusive product features, superior lead time, on-time delivery performance, quality and customer relationships to maintain our competitive advantage.

BACKLOG

Backlog is subject to delivery delays or program cancellations, which are beyond our control. As of December 31, 2011, firm backlog was $636,358,000, compared to $328,045,000 at December 31, 2010. The increase in backlog is mainly due to $265,385,000 in backlog from the acquisition of LaBarge, along with higher backlog for Apache and Blackhawk helicopters and C-17 and 777 aircrafts. Approximately $421,000,000 of total backlog is expected to be delivered during 2012. Trends in the Company’s overall level of backlog, however, may not be indicative of trends in future sales because the Company’s backlog is affected by timing differences in the placement of customer orders and because the Company’s backlog tends to be concentrated in several programs to a greater extent than sales.

ENVIRONMENTAL MATTERS

Our business, operations and facilities are subject to numerous stringent federal, state and local environmental laws and regulations issued by government agencies, including the Environmental Protection Agency, or EPA. Among other matters, these regulatory authorities impose requirements that regulate the emission, discharge, generation, management, transport and disposal of hazardous materials, pollutants and contaminants. These regulations govern public and private response actions to hazardous or regulated substances that threaten to release, or have been released to the environment, and they require us to obtain and maintain licenses and permits in connection with our operations. We may also be required to investigate and remediate the effects of the release or disposal of materials at sites associated with past and present operations. Additionally, this extensive regulatory framework imposes significant compliance burdens and risks on us. We anticipate that capital expenditures will continue to be required for

10

Table of Contents

the foreseeable future to upgrade and maintain our environmental compliance efforts. We do not expect to spend a material amount on capital expenditures for environmental compliance during 2012.

DAS has been directed by California environmental agencies to investigate and take corrective action for ground water contamination at its facilities located in El Mirage and Monrovia, California. Based on currently available information, the Company has established a reserve for its estimated liability for such investigation and corrective action in the approximate amount of $1,509,000. DAS also faces liability as a potentially responsible party for hazardous waste disposed at two landfills located in Casmalia and West Covina, California. DAS and other companies and government entities have entered into consent decrees with respect to each landfill with the United States Environmental Protection Agency and/or California environmental agencies under which certain investigation, remediation and maintenance activities are being performed. Based on currently available information, at the West Covina landfill the Company preliminarily estimates that the range of its liabilities in connection with the landfill is between approximately $700,000 and $3,300,000. The Company established a reserve for its estimated liability and has been making payments against this liability. The balance in the reserve included in the Company’s liabilities, in connection with the West Covina landfill was approximately $700,000 at December 31, 2011. The Company’s ultimate liability in connection with these matters will depend upon a number of factors, including changes in existing laws and regulations, the design and cost of construction, operation and maintenance activities, and the allocation of liability among potentially responsible parties.

In the normal course of business, Ducommun and its subsidiaries are defendants in certain other litigation, claims and inquiries, including matters relating to environmental laws. In addition, the Company makes various commitments and incurs contingent liabilities. While it is not feasible to predict the outcome of these matters, the Company does not presently expect that any sum it may be required to pay in connection with these matters would have a material adverse effect on its consolidated financial position, results of operations or cash flows.

EMPLOYEES

We employ approximately 3,541 people. Our DAS business is a party to a collective bargaining agreement, expiring July 1, 2012, with labor unions at its Monrovia, California facility covering approximately 273 full-time hourly employees at year end 2011. Our DLT business is also a party to collective bargaining agreements, expiring January 11, 2016, at the two Joplin, Missouri facilities we acquired in the LaBarge acquisition, covering approximately 243 employees. If any of these unionized workers were to engage in a strike or other work stoppage, if we are unable to negotiate acceptable collective bargaining agreements with the unions, or if other employees were to become unionized, we could experience a significant disruption of our operations and higher ongoing labor costs and possible loss of customer contracts, which could have an adverse effect on our business and results of operations. We have not experienced any material labor-related work stoppage and consider our relations with our employees to be good.

AVAILABLE INFORMATION

The Company’s Internet website address is www.ducommun.com. The Company makes available through its Internet website its annual report on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K, and amendments to those reports as soon as reasonably practicable after filing with the Securities and Exchange Commission.

The Company’s business, financial condition, results of operations and cash flows may be affected by known and unknown risks, uncertainties and other factors. Any of these risks, uncertainties and other factors could cause the Company’s future financial results to differ materially from recent financial results or from currently anticipated future financial results. In addition to those noted elsewhere in this report, the Company is subject to the following risks and uncertainties:

Risks Related to the LaBarge Acquisition

The acquisition of LaBarge presents risks and uncertainties, which could cause actual results to differ materially from historical results or those expressed in or implied by any forward-looking statements. Factors that could cause actual results to differ materially include, but are not limited to: (1) the interest rate on any borrowings incurred to finance the LaBarge acquisition and operations of Ducommun and its subsidiaries; (2) risks that the acquisition disrupts current plans and operations and the potential difficulties in employee retention; (3) difficulties integrating LaBarge’s business, operations and employees into Ducommun’s business and operations; (4) the inability to recognize the benefits of the acquisition, including any potential synergies, growth, cost savings or accretive value; (5) the inability to maintain current customer and supplier relationships following the acquisition; (6) the amount of the costs, fees, expenses and charges related to the acquisition and the actual terms of certain financings that were obtained for the acquisition; and (7) the impact of the indebtedness incurred to finance the consummation of the acquisition.

The anticipated benefits of the LaBarge Acquisition may not be fully realized and may take longer to realize than expected, which may adversely affect our results of operations.

The LaBarge acquisition involves the integration of LaBarge’s operations with our existing operations, and there are uncertainties and challenges inherent with the integration of LaBarge’s business into our operations which may cause the anticipated benefits of the acquisition not being fully realized or taking longer to realize than expected. We will be required to devote significant management attention and resources to integrating LaBarge’s operations into our operations. Delays or unexpected difficulties in the integration process could adversely affect our business, financial results and financial condition. Issues that must be addressed in integrating LaBarge’s operations include, among other things:

12

Table of Contents

Even if we are able to integrate LaBarge’s operations successfully, this integration may not result in the realization of the full benefits of synergies, cost savings and operational efficiencies that we expect or the achievement of these benefits within a reasonable period of time. In addition, we may not have discovered during the due diligence process, and we may not have discovered prior to closing, all known and unknown factors regarding LaBarge that could produce unintended and unexpected consequences for us. Undiscovered factors could result in us incurring financial liabilities, which could be material, and in us not achieving the expected benefits from the LaBarge acquisition within our desired time frames, if at all.

LaBarge may have liabilities that are not known, probable or estimable at this time.

As a result of the acquisition, LaBarge became our wholly-owned subsidiary, and we therefore effectively assumed all of its liabilities, whether or not asserted. There could be unasserted claims or assessments that we failed or were unable to discover or identify in the course of performing due diligence investigations of LaBarge. In addition, there may be liabilities that are neither probable nor estimable at this time which may become probable and estimable in the future. Any such liabilities, individually or in the aggregate, could have a material adverse effect on our business. We may learn additional information about LaBarge that adversely affects us, such as unknown, unasserted or contingent liabilities and issues relating to compliance with applicable laws.

We incurred significant costs in connection with the acquisition which may adversely affect our operating results and financial condition.

We incurred approximately $30.1 million in fees and expenses in connection with the acquisition and may incur a number of other costs associated with integrating LaBarge’s operations into our operations, which cannot be estimated accurately at this time. Additional unanticipated costs may also be incurred as we integrate LaBarge’s operations in our business. Consequently, we may incur material charges in subsequent quarters to reflect additional costs associated with the acquisition. Although we expect that the elimination of duplicative costs, as

13

Table of Contents

well as the realization of other efficiencies related to the integration of LaBarge into our operations, may offset incremental transaction and transaction-related costs over time, this net benefit may not be achieved in the near term, or at all. There can be no assurance that we will be successful in our integration efforts. In addition, while we expect to benefit from leveraging distribution channels and brand names across both companies, we cannot assure that we will achieve such benefits. If the benefits of the acquisition do not exceed the costs of integrating the business of LaBarge into our business, our financial results may be adversely affected.

Integrating our business with that of LaBarge may divert our management’s attention away from operations.

Successful integration of our and LaBarge’s operations, products and personnel may place a significant burden on our management and other internal resources. The diversion of management’s attention and any difficulties encountered in the transition and integration process, could harm our business, financial conditions and operating results.

Failure to retain key employees could diminish the anticipated benefits of the LaBarge acquisition.

The success of the LaBarge acquisition will depend in part upon the retention of personnel critical to the LaBarge business due to, for example, their technical skills or management expertise. Ducommun and LaBarge, while similar, do not have the same corporate cultures, and some LaBarge employees may not want to work for us. If we are unable to retain LaBarge personnel that are critical to the successful integration and future operation of our company, we could face disruptions in operations; loss of existing LaBarge customers, key information and expertise or know-how; and unanticipated additional recruiting and training costs. In addition, the loss of key personnel could diminish the benefits of the LaBarge Acquisition actually achieved by us.

Risks Related to Our Business

Aerospace markets are cyclical.

Both the aerospace and non-aerospace markets in which we sell our products are cyclical and have experienced periodic declines. Our sales are, therefore, unpredictable and tend to fluctuate based on a number of factors, including economic conditions and developments affecting the industries and the customers served.

We depend heavily upon a concentrated base of customers which are subject to unique risks, and a significant reduction in sales to any of our major customers, or the loss of a major customer, could have a material impact on our financial results.

In fiscal year 2011, approximately 19% of Ducommun’s sales were for Boeing commercial and military aircraft programs, 9% of our sales were for Raytheon military aircraft programs, 5% of our sales were for United Technologies (Sikorsky Black Hawk helicopter) aircraft programs, 5% of our sales were to Spirit AeroSystems for various commercial programs, and 3.9% of our sales were to Owens-Illinois on various capital equipment programs. Any

14

Table of Contents

significant change in production rates by these customers would have a material effect on our results of operations and cash flows. There is no guarantee that our current significant customers will continue to buy products from us at current levels, and that we will retain any or all of our existing customers, or that we will be able to form new relationships with customers upon the loss of one or more of our existing customers. This risk may be further complicated by pricing pressures, intense competition prevalent in our industry and other factors. The loss of a significant customer could have a material adverse effect on us.

In addition, we generally make sales under purchase orders and contracts that are subject to cancellation, modification or rescheduling. Changes in the economic environment and the financial condition of the industries we serve could result in customer requests for rescheduling or cancellation of contractual orders. Some of our contracts have specific provisions relating to schedule and performance, and failure to deliver in accordance with such provisions could result in cancellations, modifications, rescheduling and/or penalties, in some cases at the customers’ convenience and without prior notice. While we have normally recovered our direct and indirect costs, if we experience such cancellations, modifications, or rescheduling that cannot be replaced in a timely fashion, this could have a material adverse effect on our financial results.

A significant portion of our business depends upon government spending.

We derive a significant portion of our business from contracts related to orders for or associated with the U.S. Government. In 2011 approximately 52% of Ducommun’s sales were derived from military and space markets. Accordingly, the success of our business depends upon government spending, which, among other factors, is influenced by:

15

Table of Contents

These and other factors could cause the government and government agencies, or prime contractors that use us as a subcontractor, to reduce their purchases under existing contracts, to exercise their rights to terminate contracts at-will or to abstain from exercising options to renew contracts, any of which could have an adverse effect on our business, financial condition and results of operations.

Further, certain U.S. Government programs in which we participate may extend for several years; however, these programs are typically funded annually. Changes in the government’s strategy and priorities may affect our existing programs and future opportunities. Our government contracts and related orders with the U.S. Government are subject to cancellation, or delay, if appropriations for subsequent performance periods are not made. In addition, we anticipate that the U.S. Department of Defense budget will be under pressure as the current administration is faced with competing national priorities. The termination of funding for existing or new U.S. Government programs could have a material adverse effect on our financial results.

We are subject to extensive regulation and audit by the Defense Contract Audit Agency.

The accuracy and appropriateness of certain costs and expenses used to substantiate our direct and indirect costs for the U.S. Government are subject to extensive regulation and audit by the Defense Contract Audit Agency, an arm of the Department of Defense. Such audits and reviews could result in adjustments to our contract costs and profitability. We have recorded contract net sales based upon costs expected to be realized upon final audit. However, we do not know the outcome of any future audits and adjustments may be required to reduce net sales or profits upon completion and final negotiation of audits. If any audit or review were to uncover inaccurate costs or improper activities, we could be subject to penalties and sanctions, including termination of contracts, forfeiture of profits, suspension of payments, fines and suspension or prohibition from conducting future business with the U.S. Government. Any such outcome could have a material adverse effect on our financial results.

Federal government contracts contain provisions giving government customers a variety of rights that are unfavorable to us and the OEMs to whom we provide products and services, including the ability to terminate a contract at any time for convenience.

As noted above, we derive a significant portion of our net sales from subcontracts under federal government prime contracts. A portion of our net sales is also derived from direct contracts with the federal government. Federal government contracts contain provisions and are subject to laws and regulations that give the government rights and remedies not typically found in commercial contracts. These provisions may allow the government to:

Table of Contents

If the U.S. Government terminates a contract for convenience, the counterparty with whom we have contracted on a subcontract may terminate its contract with us. As a result of any such termination, whether on a direct government contract or subcontract, we may recover only our incurred or committed costs, settlement expenses and profit on work completed prior to the termination. If the U.S. Government terminates a direct contract with us for default, we may not even recover those amounts and instead may be liable for excess costs incurred by the U.S. Government in procuring undelivered items and services from another source. Contracts with foreign governments generally contain similar provisions relating to termination at the convenience of the customer.

In addition, the U.S. Government is typically required to open all programs to competitive bidding and, therefore, may not automatically renew any of its prime contracts. If one or more of our government prime or subcontracts is terminated or cancelled, our failure to replace sales generated from such contracts would result in lower sales and have an adverse effect on our earnings, which would adversely affect our business, results of operations and financial condition.

Some of our contracts with the U.S. Government are classified which may limit investor insight into portions of our business.

We derive a portion of our net sales from programs with the U.S. Government that are subject to security restrictions (classified programs), which preclude the dissemination of information that is classified for national security purposes. We are limited in our ability to provide details about these classified programs, their risks or any disputes or claims relating to such programs. As a result, you might have less insight into our classified programs than our other businesses and therefore less ability to fully evaluate the risks related to our classified business.

We face risks associated with competitive pricing pressures, which could cause price reductions, reduced profitability and loss of market share.

The aerospace and electronics manufacturing service (EMS) industries are highly competitive and competitive pressures may adversely affect us. In both of these industries we compete worldwide with a number of domestic and international companies that have substantially greater manufacturing, purchasing, marketing and financial resources than us. In the electronic manufacturing service industry, many of our customers have the in-house capability to fulfill their manufacturing requirements. Our larger competitors may be able to vie more effectively for very large-scale contracts. Our larger competitors also may be able to provide clients with different or greater capabilities or benefits than we can provide in areas such as technical qualifications, past performance on large-scale contracts, geographic presence, price and availability of key professional personnel. Our competitors may have established relationships among themselves or with third parties, including through mergers and acquisitions that could increase their ability to address customer needs. They may establish new relationships and new competitors or competitive alliances may emerge. If we are unable to successfully compete for new business, our net sales growth and operating margins may decline.

In addition, we are exposed to the introduction of lower priced competitive capabilities, significant price reductions by competitors or significant pricing pressures from customers. We are experiencing competitive pricing pressures. These pressures have had, and are expected to continue to have, an adverse effect on our financial condition and operating results. Further, there can be no assurance that competition from existing or potential competitors in other segments of our business will not have a material adverse effect on our financial results. If we do not continue to compete effectively and win contracts, our future business, financial condition, results of operations and our ability to meet our financial obligations may be materially compromised.

We use estimates when bidding on contracts and may not have the ability to control, and may not accurately estimate, costs associated with performing under fixed-price contracts. We therefore face risks of cost overruns and losses on fixed-price contracts. In addition, when determining the cost of sales to be recognized under certain long-term contracts, we are required to estimate total costs to complete the contract.

We sell many of our products under firm, fixed-price contracts providing for a fixed price for the products regardless of the production costs incurred by us. In many cases, we make multi-year firm, fixed-price commitments to our customers, without assurance that our anticipated production costs will be achieved. Contract bidding and accounting require judgment relative to assessing risks, estimating contract net sales and costs and making assumptions for scheduling and technical issues. For example, assumptions have to be made regarding the length of time to complete the contract, because costs include expected increases in prices for materials and wages, which can be particularly difficult to estimate for contracts with new customers. Similarly, assumptions have to be made regarding the future impact of our efficiency initiatives and cost reduction efforts. In order to realize a profit on these contracts, we must, when we bid these contracts, accurately estimate our costs to complete the contracts. Our failure to accurately estimate these costs can result in cost overruns, which result in reduced or lost profits. Because of the significance of the judgments and estimates involved, it is possible that materially

18

Table of Contents

different amounts could be obtained if different assumptions were used or if the underlying circumstances were to change. For example, if we experience manufacturing inefficiencies, start-up costs or increases in the cost of labor, materials, outside processing, overhead and other factors, our production costs may be adversely affected. Therefore, any changes in our underlying assumptions, circumstances or estimates could have a material adverse effect on our financial results.

In addition, we also face the risk of increased costs due to a rise in the prices of raw materials and components used in the manufacture of our products, including aluminum, titanium, steel and carbon fibers. Although these materials are generally available from a number of vendors and are generally in adequate supply, we have, from time to time, experienced increases in lead times for, and deterioration in availability of, aluminum, titanium and certain other materials. Moreover, certain components, supplies and raw materials for our operations are purchased from single sources. In such instances, we strive to develop alternative sources and design modifications to minimize the potential for business interruptions.

Risks associated with operating and conducting our business outside the United States could adversely impact us.

We have facilities in Thailand and Mexico and derive a portion of our net sales from direct foreign sales. Further, our customers may derive portions of their sales to non-U.S. customers. As a result, we are subject to the risks of conducting and operating our business internationally, including:

19

Table of Contents

While the impact of these factors is difficult to predict, any one or more of these factors could have a material adverse effect on our financial results.

Our products and processes are subject to risks from changes in technology.

Our products and processes are subject to risks of obsolescence as a result of changes in technology. The future success of our business will depend in large part upon our and our customers’ ability to maintain and enhance technological capabilities, develop and market manufacturing services that meet changing customer needs and successfully anticipate or respond to technological advances in manufacturing processes on a cost-effective and timely basis. To address this risk, we invest in product design and development, and undertake capital expenditures. There can be no guarantee that our product design and development efforts will be successful, or that funds required to be invested in product design and development or incurred as capital expenditures will not increase materially in the future.

Many of our contracts require innovative design capabilities, are technologically complex, require state-of-the-art manufacturing expertise, or are dependent upon factors beyond our control.

We manufacture and assist in the design of technologically advanced and innovative products that are applied by our customers in a variety of environments. Problems and delays in development or delivery of our products and services, which could prevent us from meeting our contractual requirements, include changes in our customers’ required designs, acceptance of the customers’ designs in the marketplace, technology, licensing and patent rights, labor, learning curve assumptions, materials and components, as well as the timing of purchase orders placed or required delivery dates, variation in demand for customers’ products, federal government funding, regulatory changes affecting customers’ industries, customer efforts to manage their inventory, changes in customers’ manufacturing strategies and customers’ technical problems or issues. Any such problems or delays could have a material adverse effect on our financial results.

We face risks associated with acquisitions and dispositions of businesses.

A key element of our long-term strategy has been growth through acquisitions. We are continuously reviewing and actively pursuing other acquisitions. Acquisitions, including the LaBarge Acquisition, may require us to incur additional indebtedness, resulting in increased leverage. Any significant acquisition, including the LaBarge acquisition, may result in a material weakening of our financial position and a material increase in our cost of borrowings. Acquisitions also may require us to issue additional equity, resulting in dilution to existing stockholders. This additional financing for acquisitions and capital expenditures may not be available on terms acceptable or favorable to us. Acquired businesses, including LaBarge, may not achieve anticipated results, which could have a material adverse effect on our financial condition, results of operations and cash flows. We also periodically review our existing

20

Table of Contents

businesses to determine if they are consistent with our strategy. We have sold, and may sell in the future, business units and product lines, which may result in either a gain or loss upon disposition.

Our acquisition strategy exposes us to risks. We may not be able to consummate acquisitions on satisfactory terms or, if any acquisitions are consummated, to satisfactorily integrate these acquired businesses. Our ability to grow by acquisition is dependent on, among other factors, the availability of suitable acquisition candidates. Growth by acquisition involves risks that could have a material adverse effect on our business, financial condition and operating results, including difficulties in integrating the operations and personnel of acquired companies, the potential amortization of acquired intangible assets, potential impairment of goodwill and the potential loss of key customers or employees of acquired companies

Goodwill and/or other intangible assets could be impaired in the future, resulting in substantial losses and write-downs.

In assessing the recoverability of goodwill, management is required to make certain critical estimates and assumptions. These estimates and assumptions include improvements in manufacturing efficiency, reductions in operating costs and obtain increases in sales and backlog. Due to many variables inherent in the estimation of a business’s fair value and the relative size of our recorded goodwill, differences in estimates and assumptions may have a material effect on the results of our impairment analysis. If any of these or other estimates and assumptions are not realized in the future, or if market multiples decline, we may be required to record an additional impairment charge for goodwill. Ducommun’s goodwill as of December 31, 2011 was $163.8 million, or 20.3 % of total assets.

Significant consolidation in the aerospace and defense industry could adversely affect our business and financial results.

The aerospace and defense industry is experiencing significant consolidation, including our customers, competitors and suppliers. Consolidation among our customers may result in delays in the award of new contracts and losses of existing business. Consolidation among our competitors may result in larger competitors with greater resources and market share, which could adversely affect our ability to compete successfully. Consolidation among our suppliers may result in fewer sources of supply and increased cost to us.

Our failure to meet the quality or delivery expectations of customers could adversely affect our business and financial results.

Our ability to deliver our products and services on schedule is dependent upon a variety of factors, including execution of internal performance plans, availability of raw materials, internal and supplier produced parts and structures, conversion of raw materials into parts and assemblies and performance of suppliers and others. Our customers expect on-time delivery and quality with respect to our products. In some cases, we do not presently satisfy these customer expectations, particularly with respect to on-time delivery. If we fail to meet the quality or delivery expectations of our customers, this failure could lead to the loss of one or more significant customers.

21

Table of Contents

We rely on numerous third-party suppliers for components used in our production process. Certain of these components are available only from single sources or a limited number of suppliers, or similarly, customers’ specifications may require us to obtain components from a single source or certain suppliers. These and other factors, including the loss of a critical supplier, could cause disruptions or cost inefficiencies in our operations compared to our competitors that have greater direct purchasing power, which could have a material adverse effect on our financial results.

In addition, from time to time, we have experienced shortages of some of the components that we use in production. These shortages can result from strong demand for those components or from problems experienced by suppliers and can result in delays in production, which may prevent us from making scheduled shipments to customers. Our inability to make scheduled shipments could cause us to experience a reduction in sales and an increase in inventory levels and costs, and could adversely affect relationships with existing and prospective customers. Component shortages may also increase our cost of goods sold because we may be required to pay higher prices for components in short supply and redesign or reconfigure products to accommodate substitute components. As a result, component shortages could have a material adverse effect on our financial results.

Internal system or service failures could disrupt our business and impair our ability to effectively provide the products and related services we offer to our customers, which could damage our reputation and adversely affect our business, results of operations and financial condition.

Any system or service disruptions, including those caused by projects to improve our information technology systems, if not anticipated and appropriately mitigated, would have a material adverse effect on our business. We could also be subject to systems failures, including network, software or hardware failures, whether caused by us, third-party service providers, intruders or hackers, computer viruses, natural disasters, power shortages or terrorist attacks. Any such failures could cause loss of data and interruptions or delays in our business, cause us to incur remediation costs, subject us to claims and damage our reputation. In addition, the failure or disruption of our communications or utilities could cause us to interrupt or suspend our operations or otherwise adversely affect our business. Our property and business interruption insurance may be inadequate to compensate us for all losses that may occur as a result of any system or operational failure or disruption which would adversely affect our business, results of operations and financial condition.

Our operating results may fluctuate significantly and fall below expectations, as well as make future results difficult to predict.

We depend on contract awards from our customers, the size and timing of which vary from period to period. Accordingly, our results of operations have varied historically and may continue to fluctuate significantly from period to period, including on a quarterly basis. Consequently, results of operations in any period should not be considered indicative of the operating results that may be experienced in any future period. Factors that may adversely impact our quarterly and annual results include, but are not limited to, the following:

We may not have the ability to renew facilities leases on terms favorable to us and relocation of operations presents risks due to business interruption.

Certain of our manufacturing facilities and offices are leased and have lease terms that expire between 2012 and 2020. The majority of these leases provide us with the opportunity to renew the leases at our option and, if renewed, provide that rent will be equal to the fair market rental rate at the time of renewal, which could be significantly higher than our current rental rates. We may be unable to offset these cost increases by charging more for our products and services. Furthermore, continued economic conditions may continue to negatively impact and create greater pressure in the commercial real estate market, causing higher incidences of landlord default and/or lender foreclosure of properties, including properties occupied by us. While we maintain certain non-disturbance rights in most cases, it is not certain that such rights will in all cases be upheld and our continued right of occupancy in such instances is potentially jeopardized. An occurrence of any of these events could have a material adverse effect on our financial results.

23

Table of Contents

Additionally, if we choose to move any of our operations, those operations will be subject to additional relocation costs and associated risks of business interruption.

Our operations are subject to numerous laws, regulations and restrictions, and failure to comply with these laws, regulations and restrictions could subject us to liability for penalties, including termination of our U.S. Government contracts and subcontracts, disqualification from bidding on future U.S. Government contracts and subcontracts, suspension or debarment from U.S. Government contracting and various other fines and penalties.

Our contracts and operations are subject to various laws and regulations. Prime contracts with various agencies of the U.S. Government, and subcontracts with other prime contractors, are subject to numerous laws and regulations which affect how we do business with our customers and may impose added costs on our business. These laws and regulations include:

Noncompliance found by any one agency could result in fines, penalties, debarment or suspension from receiving additional contracts with all U.S. Government agencies. Given our dependence on U.S. Government business, suspension or debarment could have a material adverse effect on our financial results.

In addition, the U.S. Government may revise its procurement practices or adopt new contract rules and regulations, at any time. The U.S. Government may also face restrictions or pressure regarding the type and amount of services it may obtain from private contractors. Congressional legislation and initiatives dealing with mitigation of potential conflicts of interest, procurement reform and shifts in the buying practices of U.S. Government agencies resulting

24

Table of Contents

from those proposals, such as increased usage of fixed-price contracts which transfer some risks from the U.S. Government to the performing contractors, could have adverse effects on government contractors, including us. Any of these changes could impair our ability to obtain new contracts or subcontracts or renew contracts or subcontracts under which we currently perform when those contracts are put up for recompetition. Any new contracting methods could be costly or administratively difficult for us to implement and could adversely affect our future net sales.

In addition, our international operations subject us to numerous U.S. and foreign laws and regulations, including, without limitation, regulations relating to import-export control, technology transfer restrictions, repatriation of earnings, exchange controls, the Foreign Corrupt Practices Act and the anti-boycott provisions of the U.S. Export Administration Act. Changes in regulations or political environments may affect our ability to conduct business in foreign markets including investment, procurement and repatriation of earnings. Failure by us or our sales representatives or consultants to comply with these laws and regulations could result in certain liabilities and could possibly result in suspension or debarment from government contracts or suspension of our export privileges, which could have a material adverse effect on our financial results.

The occurrence of litigation in which we could be named as a defendant is unpredictable.

From time to time, we and our subsidiaries, including LaBarge, are involved in various legal and other proceedings that are incidental to the conduct of our business. While we believe no current proceedings, if adversely determined, could have a material adverse effect on our financial results, no assurances can be given. Any such claims may divert financial and management resources that would otherwise be used to benefit our operations and could have a material adverse effect on our financial results.

Environmental liabilities could adversely affect our financial results.

We are subject to various environmental laws and regulations, including those relating to the use, storage, transport, discharge and disposal of hazardous chemicals used during our manufacturing process. We do not carry insurance for these potential environmental liabilities. Any failure by us to comply with present or future regulations could subject us to future liabilities or the suspension of production, which could have a material adverse effect on our financial results. Moreover, some environmental laws relating to contaminated sites can impose joint and several liability retroactively regardless of fault or the legality of the activities giving rise to the contamination.

The DAS chemical milling business uses various acid and alkaline solutions in the chemical milling process, resulting in potential environmental hazards. Despite existing waste recovery systems and continuing capital expenditures for waste reduction and management, at least for the immediate future, this business will remain dependent upon the availability and cost of remote hazardous waste disposal sites or other alternative methods of disposal.

25

Table of Contents

Our DAS subsidiary has been directed by government environmental agencies to investigate and take corrective action for groundwater contamination at two of its facilities. DAS is also a potentially responsible party at certain sites at which it previously disposed of hazardous wastes. There can be no assurance that future developments, lawsuits and administrative actions and liabilities relating to environmental matters will not have a material adverse effect on our results of operations or cash flows.

In addition, certain of our customers must be in compliance with the European standard, Restriction of Hazardous Substances in Electrical and Electronic Equipment (RoHS Directive 2002-95-EC), for all products shipped to the European marketplace. The purpose of the directive is to restrict the use of hazardous substances in electrical and electronic equipment and to contribute to the environmentally sound recovery and disposal of electrical and electronic equipment waste. In addition, electronic component manufacturers must produce electronic components that are lead-free. Our Pittsburgh operation has implemented lead-free wave solder and reflow systems. We rely on numerous third-party suppliers for components used in our production process and there can be no assurances these suppliers will comply with this standard. Noncompliance could have a material adverse effect on our financial results.

Product liability claims in excess of insurance could adversely affect our financial results and financial condition.

We face potential liability for personal injury or death as a result of the failure of products designed or manufactured by us. Although we currently maintain product liability insurance (including aircraft product liability insurance), any material product liability not covered by insurance could have a material adverse effect on our financial condition, results of operations and cash flows.

Damage or destruction of our facilities caused by storms, earthquake or other causes could adversely affect our financial results and financial condition.

We have operations located in regions of the U.S. that may be exposed to damaging storms, earthquakes and other natural disasters. Although we maintain standard property casualty insurance covering our properties and may be able to recover costs associated with certain natural disasters through insurance, we do not carry any earthquake insurance because of the cost of such insurance. Many of our properties are located in Southern California, an area subject to earthquake activity. Our California facilities generated $240.4 million in net sales during fiscal year 2011. Even if covered by insurance, any significant damage or destruction of our facilities due to storms, earthquakes or other natural disasters could result in the inability to meet customer delivery schedules and may result in the loss of customers and significant additional costs to us. Thus, any significant damage or destruction of our properties could have a material adverse effect on our business, financial condition or results of operations.

We are dependent upon our ability to attract and retain key personnel.

Our success depends in part upon our ability to attract and retain key engineering, technical and managerial personnel (both at the executive and at the plant level). We face competition for management, engineering and technical personnel from other companies and

26

Table of Contents

organizations. Therefore, we may not be able to retain our existing management and other key personnel, or be able to fill new management, engineering and technical positions created as a result of expansion or turnover of existing personnel. The continued growth and expansion of our contract manufacturing business will require us to identify, hire, train and retain additional skilled and experienced personnel. Also, critical to ongoing operations at three of our facilities are the successful negotiation of collective bargaining agreements and the avoidance of organized work stoppages. The loss of members of our senior management group, or key engineering and technical personnel, the failure to meet recruitment and retention objectives or the inability to efficiently and successfully negotiate collective bargaining agreements could negatively impact our ability to grow and remain competitive in the future and could have a material adverse effect on our financial results.

Labor disruptions by our employees could adversely affect our business.

We employ approximately 3,541 people. Our DAS subsidiary is a party to a collective bargaining agreement, expiring July 1, 2012, with labor unions at its Monrovia, California facility covering 273 full-time hourly employees at year end 2011. Our Ducommun LaBarge Technologies, Inc. subsidiary is party to collective bargaining agreements, expiring January 11, 2016, at its two Joplin, Missouri facilities covering 243 people. Although we have not experienced any material labor-related work stoppage and consider our relations with our employees to be good, labor stoppages may occur in the future. If the unionized workers were to engage in a strike or other work stoppage, if we are unable to negotiate acceptable collective bargaining agreements with the unions or if other employees were to become unionized, we could experience a significant disruption of our operations, higher ongoing labor costs and possible loss of customer contracts, which could have an adverse effect on our business and results of operations.

Enacted and proposed changes in securities laws and regulations have increased our costs and may continue to increase our costs in the future.

In recent years, there have been several changes in laws, rules, regulations and standards relating to corporate governance and public disclosure, including the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”), the Sarbanes-Oxley Act of 2002 and various other new regulations promulgated by the SEC and rules promulgated by the national securities exchanges.

The Dodd-Frank Act, enacted in July 2010, expands federal regulation of corporate governance matters and imposes requirements on publicly-held companies, including us, to, among other things, provide stockholders with a periodic advisory vote on executive compensation and also adds compensation committee reforms and enhanced pay-for-performance disclosures. While some provisions of the Dodd-Frank Act are effective upon enactment, others will be implemented upon the SEC’s adoption of related rules and regulations. The scope and timing of the adoption of such rules and regulations is uncertain and accordingly, the cost of compliance with the Dodd-Frank Act is also uncertain.

Our efforts to comply with the Dodd-Frank Act and other evolving laws, regulations and standards are likely to result in increased general and administrative expenses and a

27

Table of Contents

diversion of management time and attention from revenue generating activities to compliance activities. Further, compliance with new and existing laws, rules, regulations and standards may make it more difficult and expensive for us to maintain director and officer liability insurance, and we may be required to accept reduced coverage or incur substantially higher costs to obtain coverage.

Risks Related to Our Indebtedness

Our substantial indebtedness could adversely affect our financial condition, limit our ability to raise additional capital to fund our operations and prevent us from fulfilling our debt obligations.

As a result of the LaBarge acquisition we currently have a substantial amount of indebtedness. As of December 31, 2011, we had total indebtedness of $392.2 million. Upon the satisfaction of certain conditions including, but not limited to, the agreement of lenders to provide such facilities or commitments, we also have the option to add one or more incremental term loan facilities or increase commitments under our New Revolving Credit Facility by an aggregate amount of up to $75.0 million.

If we do not generate sufficient cash flow from operations to satisfy our debt obligations, we may have to undertake alternative financing plans, such as:

We cannot assure you that we would be able to enter into these alternative financing plans on commercially reasonable terms or at all. Moreover, any alternative financing plans that we may be required to undertake would still not guarantee that we would be able to meet our debt obligations. Our inability to generate sufficient cash flow to satisfy our debt obligations, including our obligations under the Notes, or to obtain alternative financing, could materially and adversely affect our business, results of operations, financial condition and business prospects.

Our high level of debt could have important consequences to us and to the holders of the Notes, including:

28

Table of Contents

The occurrence of any one of these events could have an adverse effect on our business, financial condition, results of operations and ability to satisfy our obligations in respect of our outstanding debt.

We require a significant amount of cash to service our indebtedness. Our ability to generate cash depends upon many factors beyond our control.

Our ability to make payments on and to refinance our debt, including the Notes, and to fund planned capital expenditures and working capital increases, will depend upon our ability to generate cash in the future. Since the consummation of the acquisition, our debt service requirements have increased significantly. Our ability to generate cash is subject to economic,

29

Table of Contents

financial, competitive, legislative, regulatory and other factors that may be beyond our control. While we expect to meet all of our financial obligations, we cannot assure you that our business will generate sufficient cash flow from operations in an amount sufficient to enable us to pay our debt, including the Notes, or to fund our other liquidity needs. Any inability to generate sufficient cash flow could have a material adverse effect on our financial condition or results of operations.

The covenants in our New Credit Facilities and the indenture governing the Notes impose restrictions that may limit our operating and financial flexibility and may limit our ability to make payments on the Notes.

Our New Credit Facilities and the indenture governing the Notes contain a number of significant restrictions and covenants that limit our ability, among other things, to:

In the event that a certain minimum amount is borrowed and outstanding under the New Revolving Credit Facility, for so long as any such amount is outstanding, we will be required to comply with a total leverage ratio. Furthermore, our consolidated EBITDA, as defined by our debt facilities, as of the end of any fiscal quarter on a trailing four-quarter basis is not permitted to be less than $50.0 million.

These covenants could materially and adversely affect our ability to finance our future operations or capital needs. Furthermore, they may restrict our ability to expand, pursue our business strategies and otherwise conduct our business. Our ability to comply with these covenants may be affected by circumstances and events beyond our control, such as prevailing economic conditions and changes in regulations, and we cannot assure that we will be able to comply with such covenants. These restrictions also limit our ability to obtain future financings to withstand a future downturn in our business or the economy in general. In addition, complying

30

Table of Contents

with these covenants may also cause us to take actions that are not favorable to holders of the Notes and may make it more difficult for us to successfully execute our business strategy and compete against companies that are not subject to such restrictions. A breach of any covenant in the New Credit Facilities or the agreements and indentures governing any other indebtedness that we may have outstanding from time to time, including the indenture governing the Notes, would result in a default under that agreement or indenture after any applicable grace periods. A default, if not waived, could result in acceleration of the debt outstanding under the agreement and in a default with respect to, and an acceleration of, the debt outstanding under other debt agreements. If that occurs, we may not be able to make all of the required payments or borrow sufficient funds to refinance such debt. Even if new financing were available at that time, it may not be on terms that are acceptable to us or terms as favorable as our current agreements. If our debt is in default for any reason, our business, results of operations and financial condition could be materially and adversely affected.

We may not be able to make the change of control offer required by the indenture governing the Notes.

We may be unable to purchase the Notes upon a change of control, as defined in the indenture governing the Notes. Upon a change of control, we will be required to offer to purchase all of the Notes then outstanding for cash at 101% of the principal amount on the date of purchase plus accrued and unpaid interest, if any, on the Notes purchased to the date of purchase. If a change of control were to occur, we may not have sufficient funds to pay the change of control purchase price and we may be required to secure third-party financing to do so. However, we may not be able to obtain such financing on commercially reasonable terms, on terms acceptable to us or at all.

A change of control under the indenture governing the Notes may also result in an event of default under our New Credit Facilities which may cause the acceleration of indebtedness outstanding thereunder, in which case, proceeds of collateral pledged to secure borrowings thereunder would be used to repay such borrowings before we repay the Notes. In addition, our future indebtedness may also contain restrictions on our ability to repurchase the Notes upon certain events, including transactions that could constitute a change of control under the indenture governing the Notes. Our failure to repurchase the Notes upon a change of control would constitute an event of default under the indenture governing the Notes and would have a material adverse effect on our financial condition.

We face risks related to rating agency downgrades.

If the rating agencies reduce the rating on the Notes in the future, the market price of the Notes would be adversely affected. In addition, if any of our other outstanding debt is rated and subsequently downgraded, raising capital will become more difficult, borrowing costs under our New Revolving Credit Facility and other future borrowings may increase and the market price of the Notes may decrease.

Not applicable.

The Company occupies approximately 32 facilities with a total office and manufacturing area of over 2.2 million square feet, including both owned and leased properties. At December 31, 2011, facilities which were in excess of 50,000 square feet each were occupied as follows:

The Company’s facilities are, for the most part, fully utilized, although excess capacity exists from time to time, based on product mix and demand, but is not considered to be significant. Management believes these properties are in good condition and suitable for their present use.

Ducommun was named as a defendant in class actions filed in April, 2011 by purported stockholders of LaBarge against LaBarge, its Board of Directors and Ducommun in connection with the LaBarge acquisition. In January 2012, the Delaware Chancery Court approved the settlement of the class action which included the payment of $600,000 for plaintiffs’ attorney fees.

Ducommun is a defendant in a lawsuit entitled United States of America ex rel Taylor Smith, Jeannine Prewitt and James Ailes v. The Boeing Company and Ducommun Inc., filed in the United States District Court for the District of Kansas (the “District Court”). The lawsuit is a qui tam action brought by three former Boeing employees (“Relators”) against Boeing and Ducommun on behalf of the United States of America for violations of the United States False

32

Table of Contents

Claims Act. The lawsuit alleges that Ducommun sold unapproved parts to the Boeing Commercial Airplane Group-Wichita Division which were installed by Boeing in aircraft ultimately sold to the United States Government. The number of Boeing aircraft subject to the lawsuit has been reduced to 21 aircraft following the District Court’s granting of partial summary judgment in favor of Boeing and Ducommun. The lawsuit seeks damages, civil penalties and other relief from the defendants for presenting or causing to be presented false claims for payment to the United States Government. Although the amount of alleged damages are not specified, the lawsuit seeks damages in an amount equal to three times the amount of damages the United States Government sustained because of the defendants’ actions, plus a civil penalty of $10,000 for each false claim made on or before September 28, 1999, and $11,000 for each false claim made on or after September 28, 1999, together with attorneys’ fees and costs. One of Relators’ experts has opined that the United States Government’s damages are in the amount of $833 million. After investigating the allegations, the United States Government has declined to intervene in the lawsuit. Ducommun intends to defend itself vigorously against the lawsuit. Ducommun, at this time, is unable to estimate what, if any, liability it may have in connection with the lawsuit.

DAS has been directed by California environmental agencies to investigate and take corrective action for ground water contamination at its facilities located in El Mirage and Monrovia, California. Based on currently available information, the Company has established a reserve for its estimated liability for such investigation and corrective action of approximately $1,509,000 at December 31, 2011. DAS also faces liability as a potentially responsible party for hazardous waste disposed at two landfills located in Casmalia and West Covina, California. DAS and other companies and government entities have entered into consent decrees with respect to each landfill with the United States Environmental Protection Agency and/or California environmental agencies under which certain investigation, remediation and maintenance activities are being performed. Based on currently available information, at the West Covina landfill the Company preliminarily estimates that the range of its future liabilities in connection with the landfill is between approximately $700,000 and $3,300,000. The Company has established a reserve for its estimated liability, in connection with the West Covina landfill of approximately $700,000 at December 31, 2011. The Company’s ultimate liability in connection with these matters will depend upon a number of factors, including changes in existing laws and regulations, the design and cost of construction, operation and maintenance activities, and the allocation of liability among potentially responsible parties.

In the normal course of business, Ducommun and its subsidiaries are defendants in certain other litigation, claims and inquiries, including matters relating to environmental laws. In addition, the Company makes various commitments and incurs contingent liabilities. While it is not feasible to predict the outcome of these matters, the Company does not presently expect that any sum it may be required to pay in connection with these matters would have a material adverse effect on its consolidated financial position, results of operations or cash flows.

Not applicable.

Overview

Ducommun Incorporated (“Ducommun” or the “Company”), through its subsidiaries, provides engineering and manufacturing services primarily to the aerospace and defense industry through a wide spectrum of electronics and structural applications. We design, engineer and manufacture mission-critical aerostructure and critical electronics and electromechanical components and subassemblies. We also provide engineering, technical and program management services. Our products and services are used on domestic and foreign commercial and military aircraft, helicopter, missile and space programs, as well as in certain industrial, natural resources, medical and other commercial markets. We operate through two primary business units: DLT and DAS.

A summary of highlights for the year ended December 31, 2011 includes:

On June 28, 2011, the Company completed the acquisition of all the outstanding stock of LaBarge, Inc. (“LaBarge”), formerly a publicly-owned company based in St. Louis, Missouri for $325,315,000 (net of cash acquired and excluding acquisition costs). LaBarge had significant sales to customers in the aerospace, defense, natural resources, industrial, medical and other commercial markets. The Company provided its customers with sophisticated electronic, electromechanical and mechanical products through contract design and manufacturing services. The operating results for the acquisition have been included in the consolidated statements of operations since the date of the acquisition. For the twelve months ended December 31, 2011, operating expenses included expenses related to the acquisition of LaBarge of $16,127,000 and interest expense included the write-off of $831,000 of unamortized financing costs, as a result of the Company’s debt refinancing related to the acquisition of LaBarge.

In connection with the acquisition of LaBarge on June 28, 2011, the Company borrowed $190,000,000 under a senior secured term loan and entered into a senior secured revolving credit facility of $60,000,000. Both the term loan and the credit facility provide the option of choosing the LIBOR rate (with a Libor rate floor of 1.25%) plus 4.25%, or the Alternate Base Rate (with

38

Table of Contents

an Alternate Base Rate floor of 2.25%) plus 3.25%. The Alternate Base Rate is the greater of the (a) Prime rate and (b) Federal Funds rate plus 0.5%. The term loan requires quarterly principal payments of $475,000 beginning on September 30, 2011 and mandatory prepayment of certain amounts of excess cash flow on an annual basis beginning in 2012. Principal payments of $475,000 were paid in September and December 2011. The revolving credit facility matures on June 28, 2016 and the term loan matures on June 30, 2017. The revolving credit facility and term loan contain minimum Earnings Before Interest, Taxes, Depreciation and Amortization (“EBITDA”) and maximum leverage ratio covenants under certain circumstances, as well as limitations on future disposition of property, capital expenditures, investments, acquisitions, repurchase of stock, dividends, and outside indebtedness.

In connection with the acquisition of LaBarge, the Company also issued $200,000,000 of senior unsecured notes with interest of 9.75% per annum, payable semi-annually on January 15 and July 15 of each year, beginning in 2012 and ending 2018, at which time the entire principal amount is due. The first interest payment was made in January 2012.

The Company believes the LaBarge acquisition will allow us to expand our presence significantly in the aerospace and defense markets, as well as diversify our sales base across new markets, including industrial, natural resources, medical and other commercial end markets. More specifically, the Company expects to realize the following benefits from the LaBarge acquisition:

For the twelve months ended December 31, 2011, we generated sales of $580,914,000 and recorded a net loss of $47,583,000, which included an after-tax goodwill impairment charge of $33,416,000. EBITDA and Adjusted EBITDA for the twelve months ended December 31, 2011 were $(12,669,000) and $3,468,000, respectively. See below for certain information regarding EBITDA and Adjusted EBITDA, including reconciliations of EBITDA and Adjusted EBITDA to net income. We view EBITDA and Adjusted EBITDA as important operating performance measures that serve as a basis for measuring business segment operating performance. We use EBITDA and Adjusted EBITDA internally as complementary financial measures to evaluate the performance of our businesses and, when viewed with our GAAP financial results and accompanying reconciliations, we believe they provide additional useful information to gain an understanding of the factors and trends affecting our businesses. We have

Table of Contents

expanded our operations significantly through the recent LaBarge acquisition. As a result, our operating income has included significant charges for amortization and merger-related transaction and change-in-control compensation expenses. EBITDA and Adjusted EBITDA exclude these charges and provide meaningful information about the operating performance of our businesses apart from the amortization and merger-related transactions and change-in-control compensation expenses, as well as interest and tax expenses.

Non-GAAP Financial Measures

To supplement financial information presented in accordance with GAAP, we use additional measures to clarify and enhance the understanding of our respective past performance and future prospects such as EBITDA and Adjusted EBITDA and the related financial ratios. We define these measures, explain how they are calculated and provide reconciliations of these measures to the most comparable GAAP measure in the tables below. EBITDA, Adjusted EBITDA and the related financial ratios, as presented in this Form 10-K, are supplemental measures of our performance that are not required by, or presented in accordance with, GAAP. They are not a measurement of our financial performance under GAAP and should not be considered as alternatives to net income or any other performance measures derived in accordance with GAAP, or as an alternative to net cash provided by operating activities as measures of our liquidity. We present EBITDA, Adjusted EBITDA and the related financial ratios, as applicable, because we believe that measures such as these provide useful information with respect to our ability to meet our future debt service, capital expenditures, working capital requirements and overall operating performance. In addition, we utilize EBITDA and Adjusted EBITDA when interpreting operating trends and results of operations of our respective businesses. The presentation of these measures should not be interpreted to mean that our future results will be unaffected by unusual or nonrecurring items.

EBITDA and Adjusted EBITDA have limitations as analytical tools, and you should not consider them in isolation or as substitutes for analysis of our results as reported under GAAP. Some of these limitations are:

40

Table of Contents

Because of these limitations, EBITDA, Adjusted EBITDA and the related financial ratios should not be considered as measures of discretionary cash available to us to invest in the growth of our business or as a measure of cash that will be available to us to meet our obligations. You should compensate for these limitations by relying primarily on our GAAP results and using EBITDA and Adjusted EBITDA only supplementally. See our consolidated financial statements contained in this Form 10-K report.

However, the Company believes that EBITDA and Adjusted EBITDA are useful to an investor in evaluating our results of operations because these measures:

The following financial items have been added back to our net income when calculating EBITDA and Adjusted EBITDA:

Management uses non-GAAP measures only to supplement our GAAP results and to provide additional information that is useful to gain an understanding of the factors and trends affecting our business.

The following table sets forth a reconciliation of net income to EBITDA and Adjusted EBITDA.

Critical Accounting Policies

Critical accounting policies are those accounting policies that can have a significant impact on the presentation of our financial condition and results of operations and that require the use of subjective estimates based upon past experience and management’s judgment. Because of the uncertainty inherent in such estimates, actual results may differ from these estimates. Below are those policies applied in preparing our financial statements that management believes are the most dependent on the application of estimates and assumptions. For additional accounting policies, see Note 1 of “Notes to Consolidated Financial Statements.”

Revenue Recognition

Except as described below, the Company recognizes revenue when persuasive evidence of an arrangement exists, the price is fixed or determinable, collection is reasonably assured and delivery of products has occurred or services have been rendered. Revenue from products sold under long-term contracts is recognized by the Company on the same basis as other sale transactions.

The Company has a significant number of contracts for which net sales are accounted for under the percentage-of-completion method using the units of delivery as the measure of completion. The percentage-of-completion method requires the use of assumptions and estimates related to the contract value, the total cost at completion, and measurement of progress towards completion. These contracts are primarily fixed-price contracts that vary widely in terms of size, length of performance period and expected gross profit margins. The Company also recognizes revenue on the sale of services (including prototype products) based on the type of contract: time and materials, cost-plus reimbursement and firm-fixed price. Revenue is recognized by (i) on time and materials contracts as time is spent at hourly rates, which are

42

Table of Contents

negotiated with customers, plus the cost of any allowable materials and out-of-pocket expenses, (ii) on cost-plus reimbursement contracts based on direct and indirect costs incurred plus a negotiated profit calculated as a percentage of cost, a fixed amount or a performance-based award fee, and (iii) on fixed-price contracts on the percentage-of-completion method measured by the percentage of costs incurred to estimated total costs.

Provision for Estimated Losses on Contracts

The Company records provisions for estimated losses on contracts considering total estimated costs to complete the contract compared to total anticipated revenues in the period in which such losses are identified. The provisions for estimated losses on contracts require management to make certain estimates and assumptions, including those with respect to the future revenue under a contract and the future cost to complete the contract. Management’s estimate of the future cost to complete a contract may include assumptions as to improvements in manufacturing efficiency and reductions in operating and material costs. If any of these or other assumptions and estimates do not materialize in the future, the Company may be required to record additional provisions for estimated losses on contracts.

Goodwill

The Company’s business acquisitions have resulted in goodwill. Goodwill is not amortized but is subject to impairment tests on an annual basis in the fourth quarter and between annual tests, in certain circumstances, when events indicate an impairment may have occurred. Goodwill is tested for impairment utilizing a two-step method. In the first step, the Company determines the fair value of the reporting unit using expected future discounted cash flows and market valuation approaches (comparable Company revenue and EBITDA multiples), requiring management to make estimates and assumptions about the reporting unit’s future prospects. If the net book value of the reporting unit exceeds the fair value, the Company then performs the second step of the impairment test which requires fair valuation of all the reporting unit’s assets and liabilities in a manner similar to a purchase price allocation, with any residual fair value being allocated to goodwill. This residual fair value of goodwill is then compared to the carrying amount to determine impairment. An impairment charge will be recognized only when the estimated fair value of a reporting unit, including goodwill, is less than its carrying amount.

The Company performed its annual goodwill impairment test during the fourth quarter. As of the most recent annual impairment test (Step One) on December 31, 2011, the fair value of the DAS and Miltec reporting units exceeded their carrying values by 20% and 14%, respectively. However, the fair value of the DLT reporting unit was less than its carrying value by 4%. As a result, the second step (Step Two) of the impairment test was required for the DLT reporting unit. The tangible and intangible assets were revalued according to ASC 350 and a pre-tax impairment of goodwill of $54.3 million was recorded. The impairment 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. As of December 31, 2011, the DAS, DLT, and Miltec reporting units had $57.2 million, $98.2 million, and $8.4 million of recorded goodwill, respectively.

Other Intangible Assets

The Company amortizes purchased other intangible assets with finite lives over the estimated economic lives of the assets, ranging from one to fourteen years generally using the straight-line method. The value of other intangibles acquired through business combinations has been estimated using present value techniques which involve estimates of future cash flows. Actual results could vary, potentially resulting in impairment charges.

Accounting for Stock-Based Compensation

The Company uses a Black-Scholes valuation model in determining the stock-based compensation expense for options, net of an estimated forfeiture rate, on a straight-line basis over the requisite service period of the award. The Company has one award population with an option vesting term of four years. The Company estimated the forfeiture rate based on its historic experience.

For performance and restricted stock units, the Company calculates compensation expense, net of an estimated forfeiture rate, on a straight line basis over the requisite service/performance period of the awards. The performance stock units vest based on a three-year cumulative performance cycle. The restricted stock units, vest over various periods of time ranging from one to five years. The Company estimates the forfeiture rate based on its historic experience.

Inventories

Inventories are stated at the lower of cost or market, cost being determined on a first-in, first-out basis. Inventoried costs include raw materials, outside processing, direct labor and allocated overhead, adjusted for any abnormal amounts of idle facility expense, freight, handling costs, and wasted materials (spoilage) incurred, but do not include any selling, general and administrative expense. Costs under long-term contracts are accumulated into, and removed from, inventory on the same basis as other contracts. The Company assesses the inventory carrying value and reduces it, if necessary, to its net realizable value based on customer orders on hand, and internal demand forecasts using management’s best estimates given information currently available. The Company’s customer demand can fluctuate significantly caused by factors beyond the control of the Company. The Company maintains an allowance for potentially excess and obsolete inventories and inventories that are carried at costs that are higher than their estimated net realizable values. If market conditions are less favorable than those projected by management, such as an unanticipated decline in demand and not meeting expectations, inventory write-downs may be required.

Environmental Liabilities

Environmental liabilities are recorded when environmental assessments and/or remedial efforts are probable and costs can be reasonably estimated. Generally, the timing of these accruals coincides with the completion of a feasibility study or the Company’s commitment to a formal plan of action. Further, the Company reviews and updates its environmental accruals as circumstances change and/or additional information is obtained that reasonably could be expected to have a meaningful effect on the outcome of a matter or the estimated cost thereof.

Acquisitions

On June 28, 2011, the Company completed the acquisition of all the outstanding stock of LaBarge, Inc. (“LaBarge”), a publicly-owned company based in St. Louis, Missouri for $325,315,000 (net of cash acquired and excluding acquisition costs). LaBarge was a provider of electronics manufacturing services to aerospace, defense and other diverse markets. LaBarge provided its customers with sophisticated electronic, electromechanical and mechanical products through contract design and manufacturing. The acquisition was funded from internally generated cash, senior unsecured notes and a senior secured term loan. The operating results for this acquisition have been included in the consolidated statements of operations since the date of acquisition. For the twelve months ended December 31, 2011, operating expenses included expenses related to the acquisition of LaBarge of $16,137,000 and interest expense included the write-off of $831,000 of unamortized financing costs, as a result of the Company’s debt refinancing related to the acquisition of LaBarge.

The Company had substantial sales to Boeing, Raytheon, United Technologies, Spirit AeroSystems and Owens-Illinois. During the years 2011 and 2010, sales to these customers were as follows:

Net Sales to Top Customers

The sales and receivables relating to Boeing, Raytheon, United Technologies, Spirit AeroSystems, and Owens-Illinois, are diversified over a number of different military and space, commercial, aerospace, natural resources, industrial medical and other programs.

Sales for the year ended 2011 increased 42.2% to $580,914,000 as compared to $408,406,000 for the year ended 2010, primarily reflecting sales of $175,368,000 from the LaBarge acquisition.

Cost of Sales and Gross Profit

47

Table of Contents

Gross profit margins vary considerably by contract. Gross profit dollars increased primarily due to the increased gross profit from the LaBarge acquisition. Gross profit percentages were lower in the 2011 period primarily due to new business start-up costs of $8,843,000, or 2.3 percentage points on sales of $21,654,000 in 2011, compared to $4,948,000, or 1.8 percentage points on sales of $10,448,000 in 2010 at DAS, a high proportion of sales of lower margin products, and inventory step-up write-off related to the LaBarge acquisition.

Selling, General and Administrative Expenses

The SG&A expenses increased primarily due to SG&A expenses from the newly acquired LaBarge organization of $19,877,000 (including $3,983,000 for amortization of intangibles), and approximately $16,137,000 of expenses related to the acquisition of LaBarge.

Goodwill Impairment

The Company’s business acquisitions have resulted in goodwill. Goodwill is not amortized but is subject to impairment tests on an annual basis in the fourth quarter and between annual tests, in certain circumstances, when events indicate an impairment may have occurred. Goodwill is tested for impairment utilizing a two-step method. In the first step, the Company determines the fair value of the reporting unit using expected future discounted cash flows and market valuation approaches (comparable Company revenue and EBITDA multiples), requiring management to make estimates and assumptions about the reporting unit’s future prospects. If the net book value of the reporting unit exceeds the fair value, the Company then performs the second step of the impairment test which requires fair valuation of all the reporting unit’s assets and liabilities in a manner similar to a purchase price allocation, with any residual fair value being allocated to goodwill. This residual fair value of goodwill is then compared to the carrying amount to determine impairment. An impairment charge will be recognized only when the estimated fair value of a reporting unit, including goodwill, is less than its carrying amount.

The Company performed its annual goodwill impairment test during the fourth quarter. As of the most recent annual impairment test (Step One) on December 31, 2011, the fair value of the DAS and Miltec reporting units exceeded their carrying values by 20% and 14%, respectively. However, the fair value of the DLT reporting unit was less than its carrying value by 4%. As a result, the second step (Step Two) of the impairment test was required for the DLT reporting unit. The tangible and intangible assets were revalued according to ASC 350 and a pre-tax impairment of goodwill of $54.3 million was recorded. The impairment 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. As of December 31, 2011, the DAS, DLT, and Miltec reporting units had $57.2 million, $98.2 million, and $8.4 million of recorded goodwill, respectively.

Interest Expense

The increase in interest expense was due to higher levels of debt and associated interest rates related to the LaBarge acquisition.

Income Tax Expenses

The decrease in income tax expense in 2011 was due to lower income before taxes and higher benefits related to research and development credits, partially offset by non-deductible expenses related to the DLT goodwill impairment charge and various other expenses related to the acquisition of LaBarge. The Company had an effective tax benefit of 9.1% in 2011, compared to an effective tax rate of 19.7% in 2010.

Due to acquisition-related expenses and higher interest expenses, the Company had a net loss of $47.6 million, or $4.52 per fully diluted share for 2011, compared to net income of $19.8 million, or $1.87 per fully diluted share for 2010. The results for 2011 included an after-tax goodwill impairment charge and merger-related expenses (including cost of sales relating to the write-up of LaBarge inventory) of $3.15 and $2.77 per fully diluted share, respectively. Excluding impairment charge and the merger-related expenses, net income would have been $14.9 million, or $1.40 per fully diluted share.

Business Segment Performance

We report our financial performance based on the following two reportable segments: Ducommun Aerostructures (“DAS”) and Ducommun LaBarge Technologies (“DLT”). The results of operations among our operating segments vary due to differences in competitors, customers, extent of proprietary deliverables and performance. Ducommun AeroStructures, Inc. (“DAS”) engineers and manufactures aerospace structural components and subassemblies.
