Our Company

        We are a leading manufacturer of and provider of repair and maintenance services for aerospace systems and components, serving a broad spectrum of companies within the aerospace industry. We design, engineer, manufacture, repair and overhaul aircraft components and aerostructures. Our customers consist of original equipment manufacturers, or "OEMs," of commercial, military, regional and business aircraft and components, the U.S. military, commercial airlines and air cargo carriers, and include:

        Our diversification across OEMs and platforms, coupled with our ever-broadening product offerings, enables us to respond to the evolving needs of our customers. In addition, we are well positioned in a highly fragmented industry, as one of a limited number of companies worldwide that can offer a broad range of products, systems and services to the largest aerospace companies. For the year ended March 31, 2010 and the three months ended June 30, 2010, we generated net sales of $1.3 billion and $406.4 million, respectively. On a pro forma basis after giving effect to the Vought Acquisition, for the year ended March 31, 2010 and the three months ended June 30, 2010, we generated net sales of $3.2 billion and $763.4 million, respectively. As of June 30, 2010, we had a current backlog of approximately $3.3 billion. See "—Summary Consolidated Historical and Pro Forma Financial Data of Triumph."

        We operate through a decentralized structure of 44 aerospace companies with 64 locations in the United States, Europe, Mexico and Thailand, while maintaining an integrated marketing and sales force for all of our operating companies. Through our decentralized structure, we are able to preserve specialized skills and distinct customer bases for many of our group companies, which enhances our diversification and increases our operating flexibility to better serve our customers. Our sales and marketing team serves as a single point of customer contact for our extensive range of products. The

Table of Contents

many of our competitors. Aerospace System's products range from highly integrated systems and assemblies to kits of components to individual components and satisfy customer requirements at various stages of the manufacturing process. Aerospace Systems also performs complex machining processes, offers machining capabilities and structural component forming, and provides customers with the full range of structural components, as well as complete assemblies and subassemblies. Aerospace Systems' customers include aerospace OEMs and other tier one manufacturers who supply them, airlines, air cargo carriers, and domestic and foreign militaries. For the fiscal year ended March 31, 2010 and the three months ended June 30, 2010, Aerospace Systems generated net sales before inter-segment eliminations of $1,073.5 million and $346.9 million, respectively.

        The principal products and services of our Aerospace Systems segment prior to the Vought Acquisition are set forth below.

Acquisition of Vought Aircraft Industries, Inc.

        On June 16, 2010, we completed our acquisition of Vought. The results of Vought are included in the Aerospace Systems segment from June 16, 2010 through June 30, 2010. Vought is a leading global manufacturer of aerostructure products for commercial, military and business jet aircraft. For the twelve months ended March 28, 2010, the commercial, military and business jet aircraft end markets accounted for $1,008.1 million, $691.0 million and $258.9 million, respectively, of Vought's revenue, or 52%, 35%, and 13%, respectively, of Vought's total revenue. Vought develops and manufactures a wide range of complex aerostructures such as aircraft fuselages, wing and tail assemblies, engine nacelles, flight control surfaces as well as helicopter cabins. Vought's diverse and long-standing customer base consists of the leading aerospace OEMs, including Airbus, Boeing, Cessna, Gulfstream, Lockheed Martin, Northrop Grumman and Sikorsky, as well as the U.S. military. We believe that Vought's new product and program development expertise, engineering and composite capabilities, the importance of its aerostructure products to its OEM customer base and Vought's advanced manufacturing capabilities make Vought an important partner to its customers. Vought collaborates with its customers and provides the latest technologies to address their needs for complex, highly engineered aerostructures. Vought's products are used on many of the largest and longest running programs in the aerospace industry, including the Boeing 737, 747-8, 767 and 777, C-17 Globemaster III, CH-47 Chinook, the Airbus 330/340, Lockheed Martin C-130, Sikorsky H-60 and Gulfstream G350, G450, G500 and G550. Vought is also a key supplier to its customers on programs that it believes have high growth potential, such as the Northrop Grumman Global Hawk unmanned aerial vehicle, Boeing 787 and V-22 Osprey. For the twelve months ended March 28, 2010, Vought generated total revenue of approximately $2.0 billion. See "—Vought Summary Historical Consolidated Financial Data."

Aftermarket Services

        Aftermarket Services performs maintenance, repair and overhaul services ("MRO") for commercial and military markets on components and assemblies manufactured by third parties. Aftermarket Services also designs, engineers, manufactures, repairs and overhauls aftermarket aerospace engine components. It offers comprehensive MRO solutions, and FAA-approved repairs and parts manufacturing options in addition to providing aftermarket parts and services to airlines, air cargo carriers and third-party overhaul facilities. Aftermarket Services offers repair capability for

Table of Contents

FAA-approved assemblies which range from detailed components to complex subsystems, including APUs, thrust reversers, flight controls, engine accessories and avionics. Aftermarket Services also performs repair and overhaul services and supplies spare parts for various types of cockpit instruments and gauges for a broad range of commercial airlines on a worldwide basis. For the fiscal year ended March 31, 2010 and the three months ended June 30, 2010, Aftermarket Services generated net sales before inter-segment eliminations of $225.0 million and $59.8 million, respectively.

        The principal products and services of our Aftermarket Services segment are set forth below.

Segment Reporting

        In anticipation of the acquisition of Vought in early fiscal 2011, management began to consider certain organizational changes in an effort to align the operations reporting units. Management is currently evaluating the impact of the reorganization on the Company's externally reported segments in accordance with ASC Topic 280, Segment Reporting.

Competitive Strengths

        We believe that we will benefit from the following competitive strengths:

        Diverse Business Mix.    Through organic growth and disciplined acquisitions, we have diversified the end markets we serve in order to minimize the impact that any single segment, platform or product of the aerospace industry could have on our results. The Vought Acquisition will further diversify our product and customer base, by expanding our capabilities into complex aerostructure products and allowing us to leverage Vought's strong existing customer relationships which complement our own.

        Broad Array of Products and Services.    We provide aerospace customers a single point of purchase for a diverse array of technically complex products and services for a wide range of aerospace platforms and programs, which we believe gives us a competitive advantage in developing strategic partnerships with OEMs. We design, engineer and manufacture aircraft components to meet our customers' particular requirements. In some cases, we own the proprietary rights to these designs and, accordingly, our customers generally rely on us to regularly repair, overhaul or replace these components, which provides us with a recurring source of cash flow. For our customers, we also perform repair and overhaul services on various aviation components manufactured by third parties. Our acquisition of Vought will expand our presence in many of today's most important commercial platforms and in important fixed-wing and rotorcraft military aircraft. The success of these and other legacy programs provides a strong foundation for us and positions us for future growth on new commercial programs.

        Advanced Manufacturing and Technical Capabilities.    We are leading global manufacturers of some of the largest and most technologically advanced parts and assemblies for a diverse range of aircraft. Vought adds capabilities in aerostructures, precision assembly techniques, automated assembly processes

11

Table of Contents

and large-bed machining and fabrication of large composite fiber reinforced parts to our own capabilities, which include highly proprietary actuation products, geared products, structural components, thermal products and controls. We employ over 250 engineers supporting design programs and over 800 manufacturing engineers. Our manufacturing facilities have achieved ISO 9001 certification, a certification of internationally recognized quality standards for manufacturing.

        Significant Customer Relationships and Industry Presence.    We believe that our strong customer relationships and market-leading industry positions are the result of our dedication to meeting our customers' complex specifications, our focus on quality control and our delivery of high quality products and services. Our customer base includes nearly all of the world's major OEMs (Boeing, Airbus, Bell Helicopter, Cessna, General Electric, Gulfstream, Honeywell, Lockheed Martin, Raytheon and Sikorsky), commercial airlines, the U.S. military and air cargo carriers, including Federal Express and United Parcel Service. We are an important supplier to many long-lived commercial and military platforms, including, Airbus 330/340, Boeing 737, 747-8, 767 and 777, C-17 Globemaster III and V-22 Osprey, Lockheed Martin C-130, Sikorsky H-60, Gulfstream G350, G450, G500 and G550, and are well positioned to capitalize on future growth in these established programs and other new program launches.

        Robust Backlog.    As of June 30, 2010, our backlog was approximately $3.3 billion. Backlog is generally comprised of actual purchase orders with firm delivery dates or contract requirements generally within the next 24 months. The majority of our sales are from orders issued under long-term contracts, generally of a three to five-year duration. Our backlog increases our management's visibility on future business activity levels.

        Strong Free Cash Flow Generation.    Despite the economic challenges faced by the commercial airline industry over the last several years and the worldwide economic recession, we have been able to achieve strong and consistent cash flow generation over that time period. Legacy aircraft programs, such as the C-17, CH-47 Chinook, V-22, UH-60 Black Hawk, Global Hawk, 737, 767, 777 and A330/340 which require only moderate capital expenditures to support current delivery rates, provide us with a source of strong, recurring cash flow. We have generated this growth and consistency in our cash flow through a combination of improved expense management, prudent management of capital expenditures to meet changing industry conditions and effective management of working capital.

        Conservative Balance Sheet and Financial Strategy.    As of June 30, 2010, our total net debt to capitalization was 48.6%. In addition, as of June 30, 2010 we had $35.7 million of cash and cash equivalents and $403.1 million of availability under our revolving credit facility.

        High Barriers to Entry.    The FAA certification process and the prevalence of long-term sole source or preferred supplier contracts serve as significant barriers to entry in the aerospace component and aerostructures markets. Certification by the FAA and foreign regulatory authorities is rigorous and requires significant time and capital expenditures in order to develop the capabilities to design, manufacture, test and certify aerospace component and aerostructure parts and assemblies. To obtain the approvals necessary to compete for contracts, companies make substantial up-front investments as well as develop and demonstrate sophisticated manufacturing expertise and experienced-based industry and aircraft knowledge. In addition, OEMs frequently award long-term sole source or preferred supplier contracts for the provision of particular parts for a particular platform. As a result, with respect to many of the platforms we supply, we are the only currently qualified FAA-certified supplier of such parts. We have achieved this position by implementing the technology to enable us to meet these stringent regulatory requirements and the exacting standards of our customers.

        Experienced Leadership.    Our senior management team and directors are highly experienced in the aviation parts and services industry, operationally focused and maintain extensive business relationships from which we as a whole benefit. Our senior executives and directors have extensive experience in the

aviation industry and have successfully managed our businesses through various industry cycles. The acquisition of Vought has provided us with additional management and directors with extensive industry experience and expertise. We believe our management has the vision, focus and experience to position us for success in the future.

Business Strategy

        Our business strategy is to sustain our high level of growth through internal product development and capability expansion, as well as through acquisitions. We are committed to pursuing the strategies established during our formation in 1993 in becoming the "vendor of choice" in the worldwide aviation industry. These five core strategies are as follows:

        Develop Additional Products and Services.    We offer integrated solutions for complex systems by integrating the capabilities of our operating companies, thereby adding greater value for our customers and their products. In addition, we place a high priority on the ongoing technological development and application of our products and services. We intend to continue to introduce new aviation products and services and to acquire select products and services to take advantage of opportunities in the aerospace industry and to respond to our customers' increasing demands. We plan to further expand our position as a consolidated point of purchase to our customers by capitalizing on the ongoing trend toward outsourcing and the reduction of approved suppliers and vendors by OEMs and airlines and air cargo carriers.

        Market Complete Capabilities.    As we continue to expand our product and service offerings, we plan to leverage our network of companies to cross-sell their capabilities to our existing customers and attract new customers. We strive to be our customers' most valued partner through excellence in product and process technologies and by providing modern and efficient production facilities. In addition, we strive to build on our reputation for quality and performance and to introduce best operating practices across our operations. Our network of companies will continue to share group marketing representatives and jointly bid on projects where appropriate, while still maintaining their individual identities. We believe that the breadth of our customer relationships, capabilities and experience, and our quality of service and support will enable us to win additional customer business.

        Expand Operating Capacity.    We plan to continue to increase our operating capacity to meet our expected internal growth and to meet expected growth in the aerospace industry. We intend to continue to prudently invest in state-of-the-art plants and equipment to improve our operating efficiencies and increase our operating margins.

        Increase Our International Presence.    We intend to continue to take advantage of the expanding international market for aviation products and services as worldwide air travel increases and foreign nations purchase used aircraft that require more frequent repair and maintenance. We currently supply products and services to substantially all major commercial passenger and air cargo airlines worldwide, have manufacturing and service facilities in France, Germany, Mexico, Thailand and the United Kingdom and retain independent sales representatives in a number of foreign countries. Furthermore, we intend to globalize our production processes through initiatives such as global sourcing. We believe that our initiatives will allow us to reduce costs, expand our capabilities and provide strategic benefits to our customers. We intend to build on our existing international presence through continued market penetration and, as appropriate opportunities arise, foreign acquisitions.

        Pursue Complementary Acquisitions.    We expect to continue to grow through acquisitions of other companies, assets or product lines that add to, complement, enhance or diversify our existing aviation products and services and program portfolio. We have successfully completed 34 acquisitions since 1996. We believe the fragmented nature of a large portion of the market for aircraft products and services will provide us with additional attractive acquisition opportunities. Through selective

13

acquisitions, we aim to broaden our product offerings, add new specialized technologies, expand capacity for high-demand products and services, build on existing customer relationships and enter new markets.

The Vought Acquisition

        On June 16, 2010, we completed our previously announced acquisition of Vought pursuant to an Agreement and Plan of Merger dated March 23, 2010, by and among Triumph, Vought, Spitfire Merger Corporation, our wholly owned subsidiary ("Merger Sub") and TC Group, L.L.C. ("Carlyle"), as the Holder Representative (the "Merger Agreement"). Pursuant to the Merger Agreement, (i) Merger Sub was merged with and into Vought and (ii) then Vought was merged with and into Triumph Aerostructures, LLC, our direct wholly owned limited liability company subsidiary, with Triumph Aerostructures, LLC as the surviving entity in the mergers. The consideration for the Vought Acquisition consisted of $547.9 million in cash and 7,496,165 shares of our common stock. On June 16, 2010, we also discharged, repaid or otherwise retired approximately $603.1 million of Vought's indebtedness, which represented substantially all of Vought's outstanding indebtedness. We refer to transactions described in this paragraph as the "Vought Acquisition."

        As a result of the Vought Acquisition, certain equity funds managed by TC Group, L.L.C. (which we refer to in this prospectus as Carlyle) that were stockholders of Vought, hold approximately 31% of our outstanding shares of common stock. We refer to these equity funds in this prospectus as the Carlyle equity funds. On June 16, 2010, pursuant to a stockholders agreement, dated March 23, 2010, by and among Triumph, the Carlyle equity funds and Carlyle, we expanded the size of our board of directors and appointed Adam Palmer, Elmer Doty and Ralph Eberhart to our board of directors. The Carlyle equity funds, Carlyle and investment funds managed by each of them are prohibited from acquiring additional shares of our common stock and taking certain other actions to seek to gain control of Triumph without our prior written consent.

        We funded the Vought Acquisition through cash on hand and the following activities (the "Financing Transactions" and together with the Vought Acquisition, the "Transactions"):

•

the issuance of 7,496,165 shares of our common stock to the Vought stockholders;



•

the issuance by the Company of $350,000,000 aggregate principal amount of old notes at a price equal to 99.27% of the face value;



•

the borrowing by the Company of $350,000,000 principal amount under a new senior secured term loan credit facility (the "Term Loan Facility") at a price equal to 99.5% of the face value; and



•

the borrowing by the Company of $128,300,000, drawn under the Company's $535,000,000 revolving credit facility (the "Revolving Credit Facility" and together with the Term Loan Facility, the "Credit Facilities").

RISK FACTORS

        An investment in the new notes involves risks that could cause you to lose all or part of your original investment, including the risks described below. Please be aware that other risks may prove to be important in the future and that new risks may emerge at any time, and we cannot predict such risks or estimate the extent to which they may affect our financial performance. Prior to making a decision to tender your old notes, you should carefully consider the following discussion of risks and the other information in this prospectus, and carefully read the risks described in the documents incorporated by reference in this prospectus, including those set forth under the caption "Risk Factors" in our Quarterly Report on Form 10-Q for the quarter ended June 30, 2010. If there is any inconsistency between the information set forth in this section and any documents incorporated by reference which discuss risk factors applicable to the businesses of Triumph prior to the Vought Acquisition, you should rely on the information set forth in this section.

Risks Relating to Our Business and Our Industry

Factors that have an adverse impact on the aerospace industry may adversely affect our results of operations and liquidity.

        A substantial percentage of our gross profit and operating income on a pro forma basis after giving effect to the Vought Acquisition was derived from commercial aviation for fiscal year 2010. Our operations have been focused on designing, engineering, manufacturing, repairing and overhauling a broad portfolio of aerostructures, aircraft components, accessories, subassemblies and systems. Therefore, our business is directly affected by economic factors and other trends that affect our customers in the aerospace industry, including a possible decrease in outsourcing by OEMs and aircraft operators or projected market growth that may not materialize or be sustainable. We are also significantly dependent on sales to the commercial aerospace market, which has been cyclical in nature with significant downturns in the past. When these economic and other factors adversely affect the aerospace industry, they tend to reduce the overall customer demand for our products and services, which decreases our operating income. Economic and other factors that might affect the aerospace industry may have an adverse impact on our results of operations and liquidity. We have credit exposure to a number of commercial airlines, some of which have encountered financial difficulties. In addition, an increase in energy costs and the price of fuel to the airlines, similar to that which occurred in 2008, could result in additional pressure on the operating costs of airlines. The market for jet fuel is inherently volatile and is subject to, among other things, changes in government policy on jet fuel production, fluctuations in the global supply of crude oil and disruptions in oil production or delivery caused by sudden hostility in oil producing areas. Often airlines are unable to pass on increases in fuel prices to customers by increasing fares due to the competitive nature of the airline industry, and this compounds the pressure on operating costs. Other events of general impact such as terrorist attacks against the industry or pandemic health crises may lead to declines in the worldwide aerospace industry that could adversely affect our business and financial condition.

        In addition, demand for our maintenance, repair and overhaul services is strongly correlated with worldwide flying activity. A significant portion of the maintenance, repair and overhaul ("MRO") activity required on commercial aircraft is mandated by government regulations that limit the total time or number of flights that may elapse between scheduled MRO events. As a result, although short-term deferrals are possible, MRO activity is ultimately required to continue to operate the aircraft in revenue-producing service. Therefore, over the intermediate and long term, trends in the MRO market are closely related to the size and utilization level of the worldwide aircraft fleet, as reflected by the number of available seat miles, commonly referred to as ASMs, and cargo miles flown. Consequently, conditions or events which contribute to declines in worldwide ASMs and cargo miles flown, such as those mentioned above, could negatively impact our MRO business.

Table of Contents

Cancellations, reductions or delays in customer orders may adversely affect our results of operations.

        Our overall operating results are affected by many factors, including the timing of orders from large customers and the timing of expenditures to manufacture parts and purchase inventory in anticipation of future sales of products and services. A large portion of our operating expenses are relatively fixed. Because several of our operating locations typically do not obtain long-term purchase orders or commitments from our customers, they must anticipate the future volume of orders based upon the historic purchasing patterns of customers and upon our discussions with customers as to their anticipated future requirements. These historic patterns may be disrupted by many factors, including changing economic conditions, inventory adjustments, or work stoppages or labor disruptions at our customers. Cancellations, reductions or delays in orders by a customer or group of customers could have a material adverse effect on our business, financial condition and results of operations.

We may fail to realize all of the expected benefits of the Vought Acquisition.

        On June 16, 2010, we completed the Vought Acquisition. Vought was a company with revenues almost twice our revenues prior to the acquisition and approximately as many employees. The Vought Acquisition is by far the largest acquisition we have made. The success of the Vought Acquisition will depend, in part, on our ability to realize the anticipated benefits from combining the businesses of Triumph and Vought. However, to realize these anticipated benefits, we must successfully combine the businesses. If we are not able to achieve these objectives, or do not do so in a timely manner, the anticipated benefits of the Vought Acquisition may not be realized fully or at all or may take longer to realize than expected.

        In addition, it is possible that the integration process could result in the loss of key employees, the disruption of each company's ongoing businesses or inconsistencies in standards, controls, procedures and policies that adversely affect our ability to maintain relationships with customers, suppliers and employees or to achieve the anticipated benefits of the Vought Acquisition. Integration efforts between the two companies will also divert management attention and resources and could have an adverse effect on us during the transition period.

Our acquisition strategy exposes us to risks, including the risk that we may not be able to successfully integrate acquired businesses.

        We have a consistent strategy to grow, in part, through the acquisition of additional businesses in the aerospace industry and are continuously evaluating various acquisition opportunities, including those outside the United States and those that may have a material impact on our business. Our ability to grow by acquisition is dependent upon, among other factors, the availability of suitable acquisition candidates. Growth by acquisition involves risks that could adversely affect our operating results, including difficulties in integrating the operations and personnel of acquired companies, the risk of diverting the attention of senior management from our existing operations, the potential amortization of acquired intangible assets, the potential impairment of goodwill and the potential loss of key employees of acquired companies. We may not be able to consummate acquisitions on satisfactory terms or, if any acquisitions are consummated, successfully integrate these acquired businesses.

A significant decline in business with a key customer could have a material adverse effect on us.

        The Boeing Company, or Boeing Commercial, Military & Space, represented approximately 52% of our net sales on a pro forma basis after giving effect to the Vought Acquisition, and on a stand-alone basis, 30% of Triumph's net sales and 66% of Vought's net sales, in each case for the twelve months ended March 31, 2010, covering virtually every Boeing plant and product. As a result, a significant reduction in purchases by Boeing could have a material adverse impact on our financial

24

Table of Contents

position, results of operations, and cash flows. In addition, some of our other group companies rely significantly on particular customers, the loss of which could have an adverse effect on those businesses.

Demand for military and defense products is dependent upon government spending.

        The military and defense market is largely dependent upon government budgets, particularly the U.S. defense budget, and even an increase in defense spending may not be allocated to programs that would benefit our business. Moreover, the new military aircraft programs in which we participate may not enter full-scale production as expected. A change in the levels of defense spending or levels of military flight operations could curtail or enhance our prospects in the military and defense market depending upon the programs affected.

        For the fiscal year ended March 31, 2010, approximately 36% of our sales on a pro forma basis after giving effect to the Vought Acquisition and 37% of Triumph sales on a stand-alone basis were derived from the military and defense market, which includes primarily indirect sales to the U.S. Government. Approximately 35% of Vought's revenue for fiscal year 2009 was derived from the military and defense market, which includes primarily indirect sales to the U.S. Government. As a result, our exposure to the military and defense market is significant.

        We also face the risk that the C-17 program could be completed upon fulfillment of currently outstanding production orders. We currently have a contract with Boeing to support C-17 production through April 2011. The President's proposed 2010 budget does not include funding for the procurement of new C-17 aircraft, although Congress has proposed adding funding for additional aircraft. Boeing currently has confirmed orders with the U.S. Air Force and various foreign militaries to produce C-17 through 2012 at a rate of approximately 10 aircraft per year. In addition there are additional orders for 2013 that have been confirmed and Boeing has reported that there is strong interest from India for 10 aircraft as well as interest from Qatar, Saudi Arabia, South Africa and Japan. These additional orders would allow production to be continued through 2014 at today's current rate. However, there can be no assurance that these additional orders will materialize. Our business could be adversely impacted if the U.S. Government does not fund additional C-17 aircraft or if additional orders from Foreign Militaries do not materialize and Boeing decides not to fund beyond their current commitment. As a result, the loss of the C-17 program and the failure to win additional work to replace the C-17 program could materially reduce our cash flow and results of operations.

Future volatility in the financial markets may impede our ability to successfully access capital markets and ensure adequate liquidity and may adversely affect our customers and suppliers.

        Future turmoil in the capital markets may impede our ability to access the capital markets when we would like, or need, to raise capital or restrict our ability to borrow money on favorable terms. Such market conditions could have an adverse impact on our flexibility to react to changing economic and business conditions and on our ability to fund our operations and capital expenditures in the future. In addition, interest rate fluctuations, financial market volatility or credit market disruptions may also negatively affect our customers' and our suppliers' ability to obtain credit to finance their businesses on acceptable terms. As a result, our customers' need for and ability to purchase our products or services may decrease, and our suppliers may increase their prices, reduce their output or change their terms of sale. If our customers' or suppliers' operating and financial performance deteriorates, or if they are unable to make scheduled payments or obtain credit, our customers may not be able to pay, or may delay payment of, accounts receivable owed to us, and our suppliers may restrict credit or impose different payment terms. Any inability of customers to pay us for our products and services or any demands by suppliers for different payment terms, may adversely affect our earnings and cash flow.

Our international sales and operations are subject to applicable laws relating to trade, export controls and foreign corrupt practices, the violation of which could adversely affect our operations.

        We must comply with all applicable export control laws and regulations of the United States and other countries. United States laws and regulations applicable to us include the Arms Export Control Act, the International Traffic in Arms Regulations ("ITAR"), the Export Administration Regulations ("EAR") and the trade sanctions laws and regulations administered by the United States Department of the Treasury's Office of Foreign Assets Control ("OFAC"). EAR restricts the export of dual-use products and technical data to certain countries, while ITAR restricts the export of defense products, technical data and defense services. The U.S. Government agencies responsible for administering EAR and ITAR have significant discretion in the interpretation and enforcement of these regulations. We cannot provide services to certain countries subject to United States trade sanctions unless we first obtain the necessary authorizations from OFAC. In addition, we are subject to the Foreign Corrupt Practices Act ("FCPA") which generally bars bribes or unreasonable gifts to foreign governments or officials.

        Violations of these laws or regulations could result in significant additional sanctions including fines, more onerous compliance requirements, more extensive debarments from export privileges, loss of authorizations needed to conduct aspects of our international business and criminal penalties and may harm our ability to enter into contracts with the U.S. government. A future violation of ITAR or the other regulations enumerated above could materially adversely affect our business, financial condition and results of operations.

Our expansion into international markets may increase credit, currency and other risks, and our current operations in international markets expose us to such risks.

        As we pursue customers in Asia, South America and other less developed aerospace markets throughout the world, our inability to ensure the creditworthiness of our customers in these areas could adversely impact our overall profitability. In addition, with operations in China, Germany, Mexico, Thailand and the United Kingdom, and customers throughout world, we will be subject to the legal, political, social and regulatory requirements and economic conditions of other jurisdictions. In the future, we may also make additional international capital investments, including further acquisitions of companies outside the United States or companies having operations outside the United States. Risks inherent to international operations include, but are not limited to, the following:

•

difficulty in enforcing agreements in some legal systems outside the United States;



•

imposition of additional withholding taxes or other taxes on our foreign income, tariffs or other restrictions on foreign trade and investment, including currency exchange controls;



•

fluctuations in exchange rates which may affect demand for our products and services and may adversely affect our profitability in U.S. dollars;



•

inability to obtain, maintain or enforce intellectual property rights;



•

changes in general economic and political conditions in the countries in which we operate;



•

unexpected adverse changes in the laws or regulatory requirements outside the United States, including those with respect to environmental protection, export duties and quotas;



•

failure by our employees or agents to comply with U.S. laws affecting the activities of U.S. companies abroad;



•

difficulty with staffing and managing widespread operations; and



•

difficulty of and costs relating to compliance with the different commercial and legal requirements of the countries in which we operate.

We may need additional financing for acquisitions and capital expenditures and additional financing may not be available on terms acceptable to us.

        A key element of our strategy has been, and continues to be, internal growth supplemented by growth through the acquisition of additional aerospace companies and product lines. In order to grow internally, we may need to make significant capital expenditures, such as investing in facilities in low cost countries, and may need additional capital to do so. Our ability to grow is dependent upon, and may be limited by, among other things, access to markets and conditions of markets, availability under the Revolving Credit Facility and Securitization Facility and by particular restrictions contained in the Revolving Credit Facility and our other financing arrangements. In that case, additional funding sources may be needed, and we may not be able to obtain the additional capital necessary to pursue our internal growth and acquisition strategy or, if we can obtain additional financing, the additional financing may not be on financial terms that are satisfactory to us.

Competitive pressures may adversely affect us.

        We have numerous competitors in the aerospace industry. We compete primarily with the top-tier systems integrators and the manufacturers that supply them, some of which are divisions or subsidiaries of OEMs and other large companies that manufacture aircraft components and subassemblies. Our OEM competitors, which include Boeing, Airbus, Bell Helicopter, Cessna, Gulfstream, Honeywell, Lockheed Martin, Northrop Grumman, Raytheon, Rolls Royce and Sikorsky may choose not to outsource production of aerostructures or other components due to, among other things, their own direct labor and overhead considerations, capacity utilization at their own facilities and desire to retain critical or core skills. Consequently, traditional factors affecting competition, such as price and quality of service, may not be significant determinants when OEMs decide whether to produce a part in-house or to outsource. We also face competition from non-OEM component manufacturers including, Alenia Aeronautica, Fuji Heavy Industries, GKN Westland Aerospace (U.K.), Goodrich Corp., Kawasaki Heavy Industries, Mitsubishi Heavy Industries, Spirit AeroSystems and Stork Aerospace. Competition for the repair and overhaul of aviation components comes from three primary sources: OEMs, major commercial airlines and other independent repair and overhaul companies.

We may need to expend significant capital to keep pace with technological developments in our industry.

        The aerospace industry is constantly undergoing development and change and it is likely that new products, equipment and methods of repair and overhaul service will be introduced in the future. In order to keep pace with any new developments, we may need to expend significant capital to purchase new equipment and machines or to train our employees in the new methods of production and service.

The construction of aircraft is heavily regulated and failure to comply with applicable laws could reduce our sales or require us to incur additional costs to achieve compliance, and we may incur significant expenses to comply with new or more stringent governmental regulation.

        The aerospace industry is highly regulated in the United States by the FAA and in other countries by similar agencies. We must be certified by the FAA and, in some cases, by individual OEMs in order to engineer and service parts, components and aerostructures used in specific aircraft models. If any of our material authorizations or approvals were revoked or suspended, our operations would be adversely affected. New or more stringent governmental regulations may be adopted, or industry oversight heightened in the future, and we may incur significant expenses to comply with any new regulations or any heightened industry oversight.

Some contractual arrangements with customers may cause us to bear significant up-front costs that we may not be able to recover.

        Many new aircraft programs require that major suppliers bear the cost of design, development and engineering work associated with the development of the aircraft usually in exchange for a long-term agreement to supply critical parts once the aircraft is in production. If the aircraft fails to reach the full production stage or we fail to win the long-term contract, the outlays we have made in research and development and other start-up costs may not generate our anticipated return on investment.

We may not realize our anticipated return on capital commitments made to expand our capabilities.

        We continually make significant capital expenditures to implement new processes and to increase both efficiency and capacity. Some of these projects require additional training for our employees and not all projects may be implemented as anticipated. If any of these projects do not achieve the anticipated increase in efficiency or capacity, our returns on these capital expenditures may be lower than expected.

Any product liability claims in excess of insurance may adversely affect our financial condition.

        Our operations expose us to potential liability for personal injury or death as a result of the failure of an aircraft component that has been serviced by us or the failure of an aircraft component designed or manufactured by us. While we believe that our liability insurance is adequate to protect us from these liabilities, our insurance may not cover all liabilities. Additionally, as the number of insurance companies providing general aviation product liability insurance coverage has decreased in recent years, insurance coverage may not be available in the future at a cost acceptable to us. Any material liability not covered by insurance or for which third-party indemnification is not available could have a material adverse effect on our financial condition.

The lack of available skilled personnel may have an adverse effect on our operations.

        From time to time, some of our operating locations have experienced difficulties in attracting and retaining skilled personnel to design, engineer, manufacture, repair and overhaul sophisticated aircraft components. Our ability to operate successfully could be jeopardized if we are unable to attract and retain a sufficient number of skilled personnel to conduct our business. Additionally, the service of key members of the Vought management team and other personnel are expected to be critical to ensure the smooth and timely integration of Vought's business into Triumph.

Any exposure to environmental liabilities may adversely affect us.

        Our business, operations and facilities are subject to numerous stringent federal, state, local and foreign environmental laws and regulations, and we are subject to potentially significant fines or penalties, including criminal sanctions, if we fail to comply with these requirements. Pursuant to certain environmental laws, a current or previous owner or operator of a contaminated site may be held liable for the entire cost of investigation, removal or remediation of hazardous materials at such property, whether or not the owner or operator knew of, or was responsible for, the presence of any hazardous materials. Although management believes that our operations and facilities are in material compliance with such laws and regulations, future changes in such laws, regulations or interpretations thereof or the nature of our operations or regulatory enforcement actions which may arise, may require us to make significant additional capital expenditures to ensure compliance in the future. Certain of our facilities, including facilities acquired and operated by us or one of our subsidiaries have at one time or another been under active investigation for environmental contamination by federal or state agencies when acquired and, at least in some cases, continue to be under investigation or subject to remediation for potential or identified environmental contamination. Lawsuits, claims and costs involving

28

Table of Contents

environmental matters are likely to continue to arise in the future. Individual facilities of ours have also been subject to investigation on occasion for possible past waste disposal practices which might have contributed to contamination at or from remote third-party waste disposal sites. In some instances, we are indemnified by prior owners or operators and/or present owners of the facilities for liabilities which we incur as a result of these investigations and the environmental contamination found which pre-dates our acquisition of these facilities, subject to certain limitations, including but not limited to specified exclusions, deductibles and limitations on the survival period of the indemnity. We also maintain a pollution liability policy that provides coverage, subject to specified limitations, for specified material liabilities associated with the clean-up of certain on-site pollution conditions, as well as defense and indemnity for certain third-party suits (including Superfund liabilities at third-party sites), in each case, to the extent not otherwise indemnified. However, if we were required to pay the expenses related to environmental liabilities for which neither indemnification nor insurance coverage is available, these expenses could have a material adverse effect on our financial position, results of operations, and cash flows.

We are currently involved in intellectual property litigation, which could have a material and adverse impact on our profitability, and we could become so involved again in the future.

        We and other companies in our industry possess certain proprietary rights relating to designs, engineering, manufacturing processes and repair and overhaul procedures. In the event that we believe that a third party is infringing upon our proprietary rights, we may bring an action to enforce such rights. In addition, third parties may claim infringement by us with respect to their proprietary rights and may initiate legal proceedings against us in the future. The expense and time of bringing an action to enforce such rights or defending against infringement claims can be significant, as in the case of the litigation arising out of the claims of Eaton Corporation discussed in "Business—Legal Proceedings." Intellectual property litigation involves complex legal and factual questions which makes the outcome of any such proceedings subject to considerable uncertainty. Not only can such litigation divert management's attention, but it can also expose the Company to damages and potential injunctive relief which, if granted, may preclude the company from making, using or selling particular products or technology. The expense and time associated with such litigation may have a material and adverse impact on our profitability.

We do not own certain intellectual property and tooling that is important to our business.

        In our overhaul and repair businesses, OEMs of equipment that we maintain for our customers increasingly include language in repair manuals relating to their equipment asserting broad claims of proprietary rights to the contents of the manuals used in our operations. Although we believe that our use of manufacture and repair manuals is lawful, there can be no assurance that OEMs will not try to enforce such claims, including through the possible use of legal proceedings, or that any such actions will be unsuccessful.

        Our business also depends on using certain intellectual property and tooling that we have rights to use pursuant to license grants under our contracts with our OEM customers. These contracts contain restrictions on our use of the intellectual property and tooling and may be terminated if we violate certain of these restrictions. Our loss of a contract with an OEM customer and the related license rights to use an OEM's intellectual property or tooling would materially adversely affect our business.

Our fixed-price contracts may commit us to unfavorable terms.

        For the year fiscal year ended March 31, 2010, a significant portion of our net sales on a pro forma basis after giving effect to the Vought Acquisition were derived from fixed-price contracts under which we have agreed to provide components or aerostructures for a price determined on the date we entered into the contract. Several factors may cause the costs we incur in fulfilling these contracts to

29

---

Table of Contents

vary substantially from our original estimates, and we bear the risk that increased or unexpected costs may reduce our profit or cause us to sustain losses on these contracts. In a fixed-price contract, we must fully absorb cost overruns, notwithstanding the difficulty of estimating all of the costs we will incur in performing these contracts. Because our ability to terminate contracts is generally limited, we may not be able to terminate our performance requirements under these contracts at all or without substantial liability and, therefore, in the event we are sustaining reduced profits or losses, we could continue to sustain these reduced profits or losses for the duration of the contract term. Our failure to anticipate technical problems, estimate delivery reductions, estimate costs accurately or control costs during performance of a fixed-price contract may reduce the profitability of a fixed-price contract or cause significant losses.

Any significant disruption from key suppliers of raw materials and key components could delay production and decrease revenue.

        We are highly dependent on the availability of essential raw materials such as carbon fiber, aluminum and titanium, and purchased engineered component parts from our suppliers, many of which are available only from single customer-approved sources. Moreover, we are dependent upon the ability of our suppliers to provide raw materials and components that meet our specifications, quality standards and delivery schedules. Our suppliers' failure to provide expected raw materials or component parts could require us to identify and enter into contracts with alternate suppliers that are acceptable to both us and our customers, which could result in significant delays, expenses, increased costs and management distraction and adversely affect production schedules and contract profitability.

        We have from time to time experienced limited interruptions of supply, and we may experience a significant interruption in the future. Our continued supply of raw materials and component parts are subject to a number of risks including:

•

availability of capital to our suppliers;



•

the destruction of our suppliers' facilities or their distribution infrastructure;



•

a work stoppage or strike by our suppliers' employees;



•

the failure of our suppliers to provide raw materials or component parts of the requisite quality;



•

the failure of essential equipment at our suppliers' plants;



•

the failure or shortage of supply of raw materials to our suppliers;



•

contractual amendments and disputes with our suppliers; and



•

geopolitical conditions in the global supply base.

        In addition, some contracts with our suppliers for raw materials, component parts and other goods are short-term contracts, which are subject to termination on a relatively short-term basis. The prices of our raw materials and component parts fluctuate depending on market conditions, and substantial increases in prices could increase our operating costs, which, as a result of our fixed price contracts, we may not be able to recoup through increases in the prices of our products.

        Due to economic difficulty, we may face pressure to renegotiate agreements resulting in lower margins. Our suppliers may discontinue provision of products to us at attractive prices or at all, and we may not be able to obtain such products in the future from these or other providers on the scale and within the time periods we require. Furthermore, substitute raw materials or component parts may not meet the strict specifications and quality standards we and our customers demand, or that the U.S. Government requires. If we are not able to obtain key products on a timely basis and at an affordable cost, or we experience significant delays or interruptions of their supply, revenues from sales of products that use these supplies will decrease.

Our operations depend on our manufacturing facilities, which are subject to physical and other risks that could disrupt production.

        Our manufacturing facilities could be damaged or disrupted by a natural disaster, war, or terrorist activity. We maintain property damage and business interruption insurance at the levels typical in our industry, however, a major catastrophe, such as an earthquake, hurricane, flood, tornado or other natural disaster at any of our sites, or war or terrorist activities in any of the areas where we conduct operations could result in a prolonged interruption of our business. Any disruption resulting from these events could cause significant delays in shipments of products and the loss of sales and customers and we may not have insurance to adequately compensate us for any of these events.

Significant consolidation by aerospace industry suppliers could adversely affect our business.

        The aerospace industry has recently experienced consolidation among suppliers. Suppliers have consolidated and formed alliances to broaden their product and integrated system offerings and achieve critical mass. This supplier consolidation is in part attributable to aircraft manufacturers more frequently awarding long-term sole-source or preferred supplier contracts to the most capable suppliers, thus reducing the total number of suppliers. This consolidation could cause us to compete against certain competitors with greater financial resources, market penetration and purchasing power. When we purchase component parts and services from suppliers to manufacture our products, consolidation reduces price competition between our suppliers, which could diminish incentives for our suppliers to reduce prices. If this consolidation continues, our operating costs could increase and it may become more difficult for us to be successful in obtaining new customers.

Due to the size and long-term nature of many of our contracts, we are required by GAAP to estimate sales and expenses relating to these contracts in our financial statements, which may cause actual results to differ materially from those estimated under different assumptions or conditions.

        Our financial statements are prepared in conformity with accounting principles generally accepted in the United States. These principles require our management to make estimates and assumptions regarding our contracts that affect the reported amounts of revenue and expenses during the reporting period. Contract accounting requires judgment relative to assessing risks, estimating contract sales and costs, and making assumptions for schedule and technical issues. Due to the size and nature of many of our contracts, the estimation of total sales and cost at completion is complicated and subject to many variables. While we base our estimates on historical experience and on various assumptions that we believe to be reasonable under the circumstances at the time made, actual results may differ materially from those estimated.

We may be subject to work stoppages at our facilities or those of our principal customers and suppliers, which could seriously impact the profitability of our business.

        At March 31, 2010, we employed 12,508 people on a pro forma basis after giving effect to the Vought Acquisition, of which 26.7% belonged to unions. Our unionized workforces and those of our customers and suppliers may experience work stoppages. For example, the International Association of Machinists-represented employees at Vought's Nashville, Tennessee, plant engaged in a strike that continued for approximately 16 weeks during 2008 and 2009. A contingency plan was implemented that allowed production to continue in Nashville during the course of that strike. Additionally, our union contract with Local 848 of UAW with employees at our Dallas and Grand Prairie, Texas, facilities expires on October 3, 2010. If we are unable to negotiate a new contract with that workforce, our operations may be disrupted and we may be prevented from completing production and delivery of products from those facilities, which would negatively impact our results of operations.

31

Table of Contents

        Many aircraft manufacturers, airlines and aerospace suppliers have unionized workforces. Strikes, work stoppages or slowdowns experienced by aircraft manufacturers, airlines or aerospace suppliers, such as the recent strike at Boeing's C-17 facilities, could reduce our customers' demand for our products or prevent us from completing production. In turn, this may have a material adverse affect on our financial condition, results of operations and cash flows.

Financial market conditions may adversely affect the benefit plan assets we have inherited from Vought, increase funding requirements and materially impact our statement of financial position.

        The benefit plan assets we have inherited from Vought as a result of the Vought Acquisition are invested in a diversified portfolio of investments in both the equity and debt categories, as well as limited investments in real estate and other alternative investments. The current market values of all of these investments, as well as the related benefit plan liabilities are impacted by the movements and volatility in the financial markets. In accordance with the Compensation—Retirement Benefits topic of the Accounting Standards Codification (ASC), we have recognized the over-funded or under-funded status of a defined benefit postretirement plan as an asset or liability in our balance sheet, and will recognize changes in that funded status in the year in which the changes occur. The funded status is measured as the difference between the fair value of the plan's assets and the projected benefit obligation. A decrease in the fair value of these plan assets or an increase in interest rates resulting from movements in the financial markets will increase the under-funded status of the plans recorded in our statement of financial position and result in additional cash funding requirements to meet the minimum required funding levels.

The U.S. Government is a significant customer of our largest customers, and we and they are subject to specific U.S. Government contracting rules and regulations.

        As a result of the Vought Acquisition, we have become a more significant provider of aerostructures to military aircraft manufacturers. The military aircraft manufacturers' business, and by extension, our business, is affected by the U.S. Government's continued commitment to programs under contract with our customers. The terms of defense contracts with the U.S. Government generally permit the government to terminate contracts partially or completely, either for its convenience or if we default by failing to perform under the contract. Termination for convenience provisions provide only for our recovery of unrecovered costs incurred or committed, settlement expenses and profit on the work completed prior to termination. Termination for default provisions provide for the contractor to be liable for excess costs incurred by the U.S. Government in procuring undelivered items from another source. On contracts where the price is based on cost, the U.S. Government may review our costs and performance, as well as our accounting and general business practices. Based on the results of such audits, the U.S. Government may adjust our contract-related costs and fees, including allocated indirect costs. In addition, under U.S. Government purchasing regulations, some of our costs, including most financing costs, portions of research and development costs, and certain marketing expenses may not be subject to reimbursement.

        We bear the potential risk that the U.S. Government may unilaterally suspend our customers or us from new contracts pending the resolution of alleged violations of procurement laws or regulations. Sales to the U.S. Government are also subject to changes in the government's procurement policies in advance of design completion. An unexpected termination of, or suspension from, a significant government contract, a reduction in expenditures by the U.S. Government for aircraft using our products, lower margins resulting from increasingly competitive procurement policies, a reduction in the volume of contracts awarded to us, or substantial cost overruns could have a material adverse effect on our financial condition, results of operations and cash flows.

We are subject to the requirements of the National Industrial Security Program Operating Manual for facility security clearance, which is a prerequisite for our ability to perform on classified contracts for the U.S. Government.

        A Department of Defense, or DoD, facility security clearance is required in order to be awarded and perform on classified contracts for the DoD and certain other agencies of the U.S. Government, which is a significant part of our business. We have obtained clearance at appropriate levels that require stringent qualifications, and it may be required to seek higher level clearances in the future. We cannot assure you that we will be able to maintain our security clearance. If for some reason our security clearance is invalidated or terminated, we may not be able to continue to perform our present classified contracts or be able to enter into new classified contracts, which could affect our ability to compete for and capture new business.

We may be unable to effectively implement the Enterprise Resource Planning (ERP) system at Vought.

        In 2009, Vought began the planning and design phase of an ERP system which is scheduled for completion in 2011. If this implementation is not managed effectively it may delay our ability to obtain accurate financial information with respect to the Vought business or obtain the information necessary to effectively manage the Vought business, which could have a material adverse effect on our financial condition and results of operations.

Risks Relating to the Exchange Offer and the New Notes

If you fail to exchange your old notes for new notes, they may be difficult to resell.

        If you do not exchange your old notes for new notes in this exchange offer, the old notes you hold will continue to be subject to the existing transfer restrictions described in the legend on the global security representing the outstanding old notes. These restrictions on transfer exist because we issued the old notes pursuant to an exemption from the registration requirements of the Securities Act and applicable state securities laws. The old notes that are not exchanged for new notes will remain restricted securities. Accordingly, those old notes may not be offered or sold, unless registered under the Securities Act and applicable state securities laws, except pursuant to an exemption from, or in a transaction not subject to, the Securities Act and applicable state securities laws. Because we anticipate that most holders of old notes will elect to participate in this exchange offer, we expect that the liquidity of the market for the old notes after the completion of this exchange offer may be substantially limited. Any old notes tendered and exchanged in the exchange offer will reduce the aggregate principal amount at maturity of the old notes not exchanged.

You may not receive the new notes in the exchange offer if the exchange offer procedures are not properly followed.

        We will issue the new notes in exchange for your old notes only if you properly tender the old notes before expiration of the exchange offer. Neither we nor the exchange agent are under any duty to give notification of defects or irregularities with respect to the tenders of the old notes for exchange. If you are the beneficial holder of old notes that are held through your broker, dealer, commercial bank, trust company or other nominee, and you wish to tender such notes in the exchange offer, you should promptly contact the person through whom your old notes are held and instruct that person to tender on your behalf.

Table of Contents

Broker-dealers may become subject to the registration and prospectus delivery requirements of the Securities Act and any profit on the resale of the new notes may be deemed to be underwriting compensation under the Securities Act.

        Any broker-dealer that acquires new notes in the exchange offer for its own account in exchange for old notes which it acquired through market-making or other trading activities must acknowledge that it will comply with the registration and prospectus delivery requirements of the Securities Act in connection with any resale transaction by that broker-dealer. Any profit on the resale of the new notes and any commission or concessions received by a broker-dealer may be deemed to be underwriting compensation under the Securities Act.

If an active trading market does not develop for the new notes, you may be unable to sell the new notes or to sell them at a price you deem sufficient.

        The new notes will be securities for which there is no established trading market. We do not intend to list the new notes on any exchange or maintain a trading market for them. We give no assurance as to:

•

the liquidity of any trading market that may develop;



•

the ability of holders to sell their new notes; or



•

the price at which holders would be able to sell their new notes.

        Even if a trading market develops, the new notes may trade at higher or lower prices than their principal amount or purchase price, depending on many factors, including:

•

prevailing interest rates;



•

the number of holders of the new notes;



•

the interest of securities dealers in making a market for the new notes;



•

the market for similar debt securities; and



•

our financial performance.

Our substantial indebtedness could adversely affect our financial health and our ability to fulfill our obligations under the new notes.

        After completing the Vought Acquisition, we have a substantial amount of indebtedness. As of June 30, 2010, our total indebtedness is $1,335.3 million and we had an additional $403.1 million available for borrowing under our Revolving Credit Facility. Our indebtedness could have important consequences to you, including:

•

making it more difficult for us to satisfy our obligations with respect to the new notes;



•

increasing our vulnerability to general adverse economic and industry conditions;



•

requiring that a portion of our cash flow from operations be used for the payment of interest on our debt, thereby reducing our ability to use our cash flow to fund working capital, capital expenditures, acquisitions and general corporate requirements;



•

limiting our ability to obtain additional financing to fund future working capital, capital expenditures, acquisitions and general corporate requirements;



•

limiting our flexibility in planning for, or reacting to, changes in our business and the aerospace and defense industry; and



•

placing us at a competitive disadvantage to our competitors that have less indebtedness.

Table of Contents

        We and our subsidiaries may be able to incur additional indebtedness in the future, including senior indebtedness and secured indebtedness. Our existing debt agreements do not fully prohibit us or our subsidiaries from doing so. If new indebtedness is added to our and our subsidiaries' current indebtedness levels, the related risks that we and they now face could intensify.

        If we are unable to generate sufficient cash flow or otherwise obtain funds necessary to make required payments on our indebtedness we would be in default. Our ability to meet our obligations will depend upon our future performance, which will be subject to prevailing economic conditions, and to financial, business and other factors, including factors beyond our control.

Some of our indebtedness is subject to floating interest rates, which would result in our interest expense increasing if interest rates rise.

        As of June 30, 2010, we had $557.2 million of indebtedness subject to floating interest rates, including $350.0 million of indebtedness under our Term Loan Facility. On a pro forma basis after giving effect to the Vought Acquisition, our cash interest expense for the fiscal year ended March 31, 2010 and the three months ended June 30, 2010, would have been approximately $77.2 million and $22.3 million, respectively. A 1% increase in floating interest rates would have increased such annual interest expense by approximately $5.3 million. Accordingly, our interest expense may increase as a result of interest rate fluctuations. The actual impact of a 1% increase would depend on the amount of floating rate debt outstanding, which fluctuates from time to time. In addition, pro forma interest expense excludes incremental interest expense attributable to our 8% Senior Subordinated Notes due 2017, issued in November 2009, the remaining proceeds of which were used to partially finance the Vought Acquisition. If this debt had been outstanding as of April 1, 2009, we would have incurred additional interest expense, including amortization of discount and finance fees of approximately $9.2 million for the fiscal year ended March 31, 2010. Increased interest expense would reduce our funds available for operations or other purposes.

Our debt agreements contain restrictions that limit our flexibility in operating our business.

        Our Revolving Credit Facility and the indentures governing our existing notes contain, and our Term Loan Facility and the indenture governing the new notes contain, various covenants that limit our ability to engage in specified types of transactions. These covenants limit our, and certain of our subsidiaries' ability to, among other things:

•

incur additional indebtedness;



•

pay dividends or make other distributions;



•

make investments;



•

create liens;



•

incur restrictions on the ability of restricted subsidiaries to pay dividends or make certain other payments;



•

sell assets, including capital stock of subsidiaries;



•

enter into sale and leaseback transactions;



•

merge or consolidate with other entities; and



•

enter into transactions with affiliates.

        Complying with these covenants may 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 who are not subject to such restrictions.

35

Table of Contents

        In addition, a breach of any of these covenants could result in a default under the Credit Facilities or our indentures. Upon the occurrence of an event of default under the Credit Facilities, the lenders could elect to declare all amounts outstanding under the Credit Facilities to be immediately due and payable and terminate all commitments to extend further credit. If we were unable to repay those amounts, the lenders under the Credit Facilities could proceed against the collateral granted to them to secure that indebtedness. The acceleration of our indebtedness under one agreement may permit acceleration of indebtedness under other agreements that contain cross-default or cross-acceleration provisions. If our indebtedness is accelerated, we may not have sufficient assets to repay our indebtedness under the Credit Facilities as well as our unsecured indebtedness, including the new notes, and we may not be able to borrow sufficient funds to refinance it. Even if we are able to obtain new financing, it may not be on commercially reasonable terms or on terms that are acceptable to us. See "Description of Other Indebtedness."

We may not be able to generate sufficient cash to service all of our indebtedness, including the new notes, and we may not be able to refinance our indebtedness on commercially reasonable terms.

        Our ability to make payment on and to refinance our debt and fund planned expenditures depends on our ability to generate cash flow in the future, which is subject to general economic, financial, competitive, legislative and regulatory factors and other factors that are beyond our control. We cannot assure you that our business will generate cash flow from operations or that future borrowings will be available to us under our credit facilities, including our Revolving Credit Facility and our receivables financing facility, in an amount sufficient to enable us to pay our debt or to fund our other liquidity needs. We cannot assure you that we will be able to refinance our borrowing arrangements or any other outstanding debt on commercially reasonable terms or at all. Refinancing our borrowing arrangements could cause us to:

•

pay interest at a higher rate or increased fees; or



•

be subject to additional or more restrictive covenants than those outlined in this prospectus.

        Our inability to generate sufficient cash flow to service our debt or refinance our indebtedness on commercially reasonable terms would have a material adverse effect on our business and results of operations.

We are dependent on dividends and other distributions from our subsidiaries.

        The Company has no operations of its own and derives substantially all of its net sales and cash flows from its subsidiaries. Our principal assets are the equity interests that we hold in our operating subsidiaries. As a result, we are dependent on dividends and other distributions from our subsidiaries to generate the funds necessary to meet our financial obligations, including the payment of principal and interest on our outstanding debt. Our subsidiaries are legally distinct from us and have no obligation to make funds available to us for such payment.

The new notes will not be secured, and therefore will be effectively subordinated to all of our and the subsidiary guarantors' existing and future secured indebtedness.

        The new notes will not be secured by any of our assets or any assets of our subsidiaries. In the event of a bankruptcy or similar proceeding involving us or our subsidiaries, our assets which serve as collateral under our secured indebtedness would be made available to satisfy our obligations under any secured indebtedness we may have, including obligations under the Credit Facilities, before any payments are made on the notes. As of June 30, 2010, we had $644.0 million of secured indebtedness outstanding. Moreover, the indenture governing the new notes permits us to incur additional indebtedness that is secured.

Claims of holders of new notes will be structurally subordinate to claims of creditors of any of our subsidiaries that do not guarantee the new notes.

        The new notes will not be guaranteed by our present and future foreign subsidiaries, domestic unrestricted subsidiaries and future subsidiaries that do not guarantee our Credit Facilities. Accordingly, claims of holders of the new notes will be structurally subordinate to the claims of creditors of these non-guarantor subsidiaries, including trade creditors. All obligations of our non-guarantor subsidiaries will have to be satisfied before any of the assets of such subsidiaries would be available for distribution, upon a liquidation or otherwise, to us or a guarantor of the notes.

        For the fiscal year ended March 31, 2010, on a pro forma basis after giving effect to the Vought Acquisition, the non-guarantor subsidiaries of the Company generated 2.5% of the Company's net sales. In addition, as of June 30, 2010, the non-guarantor subsidiaries of the Company held 6.2% of the Company's assets and 19.2% of the Company's liabilities.

The lenders under the Credit Facilities will have the discretion to release the guarantors under the Credit Facilities in a variety of circumstances, which will cause those guarantors to be released from their guarantees of the notes.

        While any obligations under the Credit Facilities remain outstanding, a guarantee of the new notes may be released without action by, or consent of, any holder of the new notes or the trustee under the indenture, if the applicable guarantor is no longer a borrower or a guarantor of obligations under the Credit Facilities or any other indebtedness. See "Description of Notes." The lenders under the Credit Facilities will have the discretion to release certain guarantees under the Credit Facilities in a variety of circumstances. You will not have a claim as a creditor against any subsidiary that is no longer a guarantor of the new notes, and the indebtedness and other liabilities, including trade payables, whether secured or unsecured, of non-guarantor subsidiaries will effectively be senior to claims of holders of the new notes.

Fraudulent conveyance laws may permit courts to void the guarantors' guarantees of the new notes in specific circumstances, which would interfere with the payment under the guarantors' guarantees.

        Federal and state statutes may allow courts, under certain circumstances described generally below, to void the guarantors' guarantees of the new notes. If such avoidance occurs, the applicable guarantors would no longer be liable in respect of the new notes and holders of the new notes might be required to return payments received from our guarantors in the event of bankruptcy or other financial difficulty of such guarantors. Under United States federal bankruptcy law and comparable provisions of state fraudulent conveyance laws, a guarantee could be set aside if, among other things, a subsidiary guarantor, at the time it incurred the debt evidenced by its guarantee:

•

incurred the guarantee with the intent of hindering, delaying or defrauding current or future creditors; or



•

received less than reasonably equivalent value or fair consideration for incurring the guarantee; and



•

was insolvent or was rendered insolvent by reason of the incurrence;



•

was engaged, or about to engage, in a business or transaction for which the assets remaining with it constituted unreasonably small capital to carry on such business; or



•

intended to incur, or believed that it would incur, debts beyond its ability to pay as those debts mature.

        The tests for fraudulent conveyance, including the criteria for insolvency, will vary depending upon the law of the jurisdiction that is being applied. Generally, however, a debtor would be considered insolvent if:

•

the sum of the debtor's debts and liabilities, including contingent liabilities, was greater than the debtor's assets at fair valuation;



•

the present fair saleable value of the debtor's assets was less than the amount required to pay the probable liability on the debtor's total existing debts and liabilities, including contingent liabilities, as they became absolute and matured; or



•

it could not pay its debts as they became due.

        In addition, each guarantee will contain a provision intended to limit the guarantor's liability to the maximum amount that it could incur without causing the incurrence of obligations under its guarantee to be a fraudulent conveyance. This provision may not be effective to protect the guarantees from being voided under fraudulent conveyance laws, or may eliminate the guarantor's obligations or reduce the guarantor's obligations to an amount that effectively makes the guarantee worthless. At least one bankruptcy court has found this kind of provision to be ineffective to protect the guarantees. If a court voids a guarantee or holds it unenforceable, you will cease to be a creditor of the applicable subsidiary guarantor.

We may be unable to repurchase the new notes if we experience a change of control.

        If we were to experience a change of control, as that term is defined in the indenture governing the new notes, we will be required to offer to purchase all of the existing new notes at 101% of their principal amount plus accrued and unpaid interest to the repurchase date. Our failure to repay holders tendering new notes upon a change of control will result in an event of default under the new notes. In certain circumstances, the Credit Facilities will prohibit repayment of the new notes without the consent of the required lenders thereunder, which consent we may not be able to obtain. In addition, the events that constitute a change of control, or an event of default, under the new notes may also require us to repay (or otherwise permit acceleration of) other indebtedness immediately. If a change of control were to occur, we cannot assure you that we would have sufficient funds to repay all such outstanding indebtedness or to purchase the new notes. We expect that we would require additional financing from third parties to fund any such purchases, and we cannot assure you that we would be able to obtain financing on satisfactory terms or at all.

Changes in our credit rating could adversely affect the market price or liquidity of the notes.

        Credit rating agencies continually revise their ratings for the companies that they follow, including us. The credit rating agencies also evaluate our industry as a whole and may change their credit ratings for us based on their overall view of our industry. We cannot be sure that credit rating agencies will maintain their initial ratings on the new notes. A negative change in our ratings could have an adverse effect on the market price of the new notes.

THE EXCHANGE OFFER

        In connection with the issuance of the old notes on June 16, 2010, we entered into a registration rights agreement with the initial purchasers, which provides for the exchange offer. The exchange offer will permit eligible holders of notes to exchange the old notes for the new notes that are identical in all material respects with the old notes, except that:

•

the new notes have been registered under the U.S. federal securities laws and will not bear any legend restricting their transfer;



•

the new notes bear a different CUSIP number from the old notes;



•

the new notes generally will not be subject to transfer restrictions and will not be entitled to registration rights; and



•

the holders of the new notes will not be entitled to earn additional interest under circumstances relating to our registration obligations under the registration rights agreement.

        The new notes will evidence the same debt as the old notes. Holders of new notes will be entitled to the benefits of the indenture.

        The following summary of certain provisions of the registration rights agreement does not purport to be complete and is subject to, and is qualified in its entirety by reference to, all the provisions of the registration rights agreement. You should refer to the exhibits that are a part of the registration statement of which this prospectus is a part for a copy of the registration rights agreement. See "Where You Can Find More Information."

General

        We are making the exchange offer to comply with our contractual obligations under the registration rights agreement. Except under limited circumstances, upon completion of the exchange offer, our obligations with respect to the registration of the old notes will terminate.

        We agreed, pursuant to the registration rights agreement, to:

•

cause to be filed within 180 days after June 16, 2010 an exchange offer registration statement with the SEC,



•

use our reasonable best efforts to cause the exchange offer registration statement to become effective as soon as practicable, but in no event later than 270 days after June 16, 2010, and



•

have the exchange offer registration statement remain effective for use by one or more participating broker-dealers until the earlier of 180 days after the date the exchange offer registration statement becomes effective and the date on which a broker-dealer is no longer required to deliver a prospectus in connection with market-making or other trading activities.

        We will commence the exchange offer promptly after the exchange offer registration statement is declared effective by the SEC. We will keep the exchange offer open for not less than 30 calendar days (or longer if required by applicable law) after the date notice of the exchange offer is mailed to the holders of the old notes.

        For each old note surrendered to us pursuant to the exchange offer, the holder of such old note will receive a new note having a principal amount equal to that of the surrendered old note. Old notes may be exchanged only in minimum denominations of $2,000 and integral multiples of $1,000 in excess of $2,000. New notes will be issued only in minimum denominations of $2,000 and integral multiples of $1,000 in excess of $2,000. Interest on each new note will accrue from the last interest payment date on which interest was paid on the old note surrendered in exchange thereof or, if no interest has been paid on the old note, from the date of its original issue.

Table of Contents

        In connection with the issuance of the old notes, we arranged for the old notes to be issued in the form of global notes through the facilities of DTC acting as depositary. The new notes will also be issued in the form of global notes registered in the name of DTC or its nominee and each beneficial owner's interest in it will be transferable in book-entry form through DTC.

        Holders of old notes do not have any appraisal or dissenters' rights in connection with the exchange offer. Old notes which are not tendered for exchange or are tendered but not accepted in connection with the exchange offer will remain outstanding and be entitled to the benefits of the indenture under which they were issued, including accrual of interest, but, subject to a limited exception, will not be entitled to any registration rights under the applicable registration rights agreement. See "—Consequences of Failure to Tender."

        We will be deemed to have accepted validly tendered old notes when and if we have given oral or written notice to the exchange agent of our acceptance. Subject to the terms and conditions of this exchange offer, delivery of new notes will be made by the exchange agent on the settlement date upon receipt of such notice. The exchange agent will act as agent for the tendering holders for the purpose of receiving the new notes from us. If any tendered old notes are not accepted for exchange because of an invalid tender, the occurrence of other events described in this prospectus or otherwise, we will return the certificates for any unaccepted old notes, at our expense, to the tendering holder as promptly as practicable after the expiration of the exchange offer.

        The exchange offer is not being made to, nor will we accept tenders for exchange from, holders of the old notes in any jurisdiction in which the exchange offer or the acceptance of it would not be in compliance with the securities or blue sky laws of that jurisdiction.

Eligibility; Transferability

        We are making this exchange offer in reliance on interpretations of the staff of the SEC set forth in several no-action letters. However, we have not sought our own no-action letter. Based upon these interpretations, we believe that you, or any other person receiving new notes, may offer for resale, resell or otherwise transfer such new notes without complying with the registration and prospectus delivery requirements of the U.S. federal securities laws, if:

•

you are, or the person or entity receiving such new notes is, acquiring such new notes in the ordinary course of business;



•

you do not, nor does any such person or entity, have an arrangement or understanding with any person or entity to participate in any distribution of the new notes (within the meaning of the Securities Act);



•

you are not, nor is any such person or entity, our affiliate as such term is defined under Rule 405 under the Securities Act; and



•

you are not acting on behalf of any person or entity who could not truthfully make these statements.

        To participate in the exchange offer, you must represent as the holder of old notes that each of these statements is true.

        In addition, each broker-dealer registered under the Exchange Act must also (i) represent that it is participating in the exchange offer for its own account and is exchanging old notes acquired as a result of market-making activities or other trading activities, (ii) confirm that it has not entered into any arrangement or understanding with the Issuer or any affiliate of the Issuer to distribute the new notes and (iii) must acknowledge that it will deliver a prospectus in connection with any resale of the new notes. The letter of transmittal states that by acknowledging that it will deliver, and by delivering, a prospectus, a broker-dealer will not be deemed to admit that it is an underwriter within the meaning of

40

Table of Contents

the Securities Act. This prospectus, as it may be amended or supplemented from time to time, may be used by a broker-dealer in connection with resale of the new notes received in exchange for the old notes where such old notes were acquired by such broker-dealer as a result of market-making activities or other trading activities. We have agreed that, for a period of 180 days after the date the exchange offer registration statement becomes effective, we will amend or supplement this prospectus in order to expedite or facilitate the disposition of any new notes by such broker-dealers.

        Any holder of old notes who is our affiliate, who does not acquire the new notes in the ordinary course of business, who intends to participate in the exchange offer for the purpose of distributing the new notes or is a broker-dealer who purchased the old notes directly from us:

•

will not be able to rely on the interpretation of the staff of the SEC set forth in the no-action letters described above; and



•

must comply with the registration and prospectus delivery requirements of the Securities Act in connection with any sale or transfer of the new notes, unless the sale or transfer is made pursuant to an exemption from those requirements.

Expiration of the Exchange Offer; Extensions; Amendments

        The exchange offer will expire at 5:00 p.m., New York City time, on                    , 2010, or the expiration date, unless we extend the exchange offer. To extend the exchange offer, we will notify the exchange agent and each registered holder of any extension before 9:00 a.m., New York City time, on the next business day after the previously scheduled expiration date. We reserve the right to extend the exchange offer, delay accepting any tendered old notes or, if any of the conditions described below under the heading "—Conditions" have not been satisfied, to terminate the exchange offer. We also reserve the right to amend the terms of the exchange offer in any manner. We will give oral or written notice of such delay, extension, termination or amendment to the exchange agent.

        If we amend the exchange offer in a manner that we consider material, we will disclose such amendment by means of a prospectus supplement, and we will extend the exchange offer so that at least five business days remain in the exchange offer following notice of the material change.

        If we determine to make a public announcement of any delay, extension, amendment or termination of the exchange offer, we will do so by making a timely release through an appropriate news agency.

        If we delay accepting any old notes or terminate the exchange offer, we promptly will pay the consideration offered, or return any old notes deposited, pursuant to the exchange offer as required by Rule 14e-1(c) under the Exchange Act.

Conditions

        Notwithstanding any other term of the exchange offer, we will not be required to accept for exchange, or issue any new notes for, any old notes, and may terminate or amend the exchange offer before the acceptance of the old notes, if:

•

we determine that the exchange offer violates any law, statute, rule, regulation or interpretation by the staff of the SEC or any order of any governmental agency or court of competent jurisdiction; or



•

any action or proceeding is instituted or threatened in any court or by or before any governmental agency relating to the exchange offer which, in our judgment, could reasonably be expected to impair our ability to proceed with the exchange offer.

41

Table of Contents

        The conditions listed above are for our sole benefit and may be asserted by us regardless of the circumstances giving rise to any of these conditions. We may waive these conditions in our reasonable discretion in whole or in part at any time and from time to time prior to the expiration date. The failure by us at any time to exercise any of the above rights shall not be considered a waiver of such right, and such right shall be considered an ongoing right which may be asserted at any time and from time to time.

        In addition, we will not accept for exchange any old notes tendered, and no new notes will be issued in exchange for those old notes, if at any time any stop order is threatened or issued with respect to the registration statement for the exchange offer and the new notes or the qualification of the indenture under the Trust Indenture Act of 1939. In any such event, we must use reasonable best efforts to obtain the withdrawal of any stop order as soon as practicable.

        In addition, we will not be obligated to accept for exchange the old notes of any holder that has not made to us the representations described under "—Eligibility; Transferability" and "Plan of Distribution."

Procedures for Tendering

        A holder of old notes who wishes to accept this exchange offer, and whose old notes are held by a custodial entity such as a bank, broker, dealer, trust company or other nominee, must instruct the custodial entity to tender and consent with respect to that holder's old notes on the holder's behalf pursuant to the procedures of the custodial entity.

        To tender in this exchange offer, a holder of old notes must either:

          (i)  complete, sign and date the letter of transmittal (or a facsimile thereof) in accordance with its instructions, including guaranteeing the signature(s) to the letter of transmittal, if required, and mail or otherwise deliver such letter of transmittal or such facsimile, together with the certificates representing the old notes specified therein, to the exchange agent at the address set forth in the letter of transmittal for receipt on or prior to the expiration date; or

         (ii)  comply with the DTC's Automated Tender Offer Program, or ATOP, procedures for book-entry transfer described below on or prior to the expiration date.

        The exchange agent and DTC have confirmed that the exchange offer is eligible for ATOP. The letter of transmittal (or facsimile thereof), with any required signature guarantees, or (in the case of book-entry transfer) an agent's message in lieu of the letter of transmittal, and any other required documents, must be transmitted to and received by the exchange agent on or prior to the expiration date of the exchange offer at one of its addresses set forth under "—Exchange Agent" in this prospectus or as set forth in the letter of transmittal. Old notes will not be deemed surrendered until the letter of transmittal and signature guarantees, if any, or agent's message, are received by the exchange agent.

        The method of delivery of old notes, the letter of transmittal, and all other required documents to the exchange agent is at the election and risk of the holder. Instead of delivery by mail, holders should use an overnight or hand delivery service, properly insured. In all cases, sufficient time should be allowed to assure delivery to and receipt by the exchange agent on or before the expiration date. Do not send the letter of transmittal or any old notes to anyone other than the exchange agent.

        All new notes will be delivered only in book-entry form through DTC. Accordingly, if you anticipate tendering other than through DTC, you are urged to contact promptly a bank, broker or other intermediary (that has the capability to hold securities custodially through DTC) to arrange for receipt of any new notes to be delivered to you pursuant to the exchange offer and to obtain the

42

---

Table of Contents

information necessary to provide the required DTC participant with account information for the letter of transmittal.

Book-Entry Delivery Procedures for Tendering Old Notes Held with DTC

        If you wish to tender old notes held on your behalf by a custodial entity with DTC, you must:

          (i)  inform your custodial entity of your interest in tendering your old notes pursuant to the exchange offer; and

         (ii)  instruct your custodial entity to tender all old notes you wish to be tendered in the exchange offer into the exchange agent's account at DTC on or prior to the expiration date. Any financial institution that is a nominee in DTC, including Euroclear and Clearstream, must tender old notes by effecting a book-entry transfer of the old notes to be tendered in the exchange offer into the account of the exchange agent at DTC by electronically transmitting its acceptance of the exchange offer through the ATOP procedures for transfer. DTC will then verify the acceptance, execute a book-entry delivery to the exchange agent's account at DTC, and send an agent's message to the exchange agent. An "agent's message" is a message, transmitted by DTC to and received by the exchange agent and forming part of a book-entry confirmation, which states that DTC has received an express acknowledgement from an organization that participates in DTC (a "participant") tendering old notes that the participant has received and agrees to be bound by the terms of the letter of transmittal and that we may enforce the agreement against the participant. A letter of transmittal need not accompany tenders effected through ATOP.

Proper Execution and Delivery of Letter of Transmittal

        Signatures on a letter of transmittal or notice of withdrawal described below (see "—Withdrawal of Tenders"), as the case may be, must be guaranteed by an eligible institution unless the old notes tendered pursuant to the letter of transmittal are tendered (i) by a holder who has not completed the box entitled "Special Delivery Instructions" or "Special Issuance and Payment Instructions" on the letter of transmittal or (ii) for the account of an eligible institution. If signatures on a letter of transmittal or notice of withdrawal are required to be guaranteed, such guarantee must be made by an eligible guarantor institution within the meaning of Rule 17Ad-15 under the Exchange Act.

        If the letter of transmittal is signed by the holder(s) of old notes tendered thereby, the signature(s) must correspond with the name(s) as written on the face of the old notes without alteration, enlargement or any change whatsoever. If any of the old notes tendered thereby are held by two or more holders, all such holders must sign the letter of transmittal. If any of the old notes tendered thereby are registered in different names on different old notes, it will be necessary to complete, sign and submit as many separate letters of transmittal, and any accompanying documents, as there are different registrations of certificates.

        If old notes that are not tendered for exchange pursuant to the exchange offer are to be returned to a person other than the holder thereof, certificates for such old notes must be endorsed or accompanied by an appropriate instrument of transfer, signed exactly as the name of the registered owner appears on the certificates, with the signatures on the certificates or instruments of transfer guaranteed by an eligible institution.

        If the letter of transmittal is signed by a person other than the holder of any old notes listed therein, such old notes must be properly endorsed or accompanied by a properly completed bond power, signed by such holder exactly as such holder's name appears on such old notes. If the letter of transmittal or any old notes, bond powers or other instruments of transfer are signed by trustees, executors, administrators, guardians, attorneys-in-fact, officers of corporations or others acting in a fiduciary or representative capacity, such persons should so indicate when signing, and, unless waived

43

---

Table of Contents

by us, evidence satisfactory to us of their authority to so act must be submitted with the letter of transmittal.

        No alternative, conditional, irregular or contingent tenders will be accepted. By executing the letter of transmittal (or facsimile thereof), the tendering holders of old notes waive any right to receive any notice of the acceptance for exchange of their old notes. Tendering holders should indicate in the applicable box in the letter of transmittal the name and address to which payments and/or substitute certificates evidencing old notes for amounts not tendered or not exchanged are to be issued or sent, if different from the name and address of the person signing the letter of transmittal. If no such instructions are given, old notes not tendered or exchanged will be returned to such tendering holder.

        All questions as to the validity, form, eligibility (including time of receipt), and acceptance and withdrawal of tendered old notes will be determined by us in our absolute discretion, which determination will be final and binding. We reserve the absolute right to reject any and all tendered old notes determined by us not to be in proper form or not to be properly tendered or any tendered old notes our acceptance of which would, in the opinion of our counsel, be unlawful. We also reserve the right to waive, in our absolute discretion, any defects, irregularities or conditions of tender as to particular old notes, whether or not waived in the case of other old notes. Our interpretation of the terms and conditions of the exchange offer (including the instructions in the letter of transmittal) will be final and binding on all parties. Unless waived, any defects or irregularities in connection with tenders of old notes must be cured within such time as we shall determine. Although we intend to notify holders of defects or irregularities with respect to tenders of old notes, neither we, the exchange agent nor any other person will be under any duty to give such notification or shall incur any liability for failure to give any such notification. Tenders of old notes will not be deemed to have been made until such defects or irregularities have been cured or waived.

        Any holder whose old notes have been mutilated, lost, stolen or destroyed will be responsible for obtaining replacement securities or for arranging for indemnification with the trustee of the old notes. Holders may contact the exchange agent for assistance with such matters.

Withdrawal of Tenders

        You may withdraw tenders of old notes at any time prior to the expiration date.

        For a withdrawal of a tender to be effective, a written or facsimile transmission notice of withdrawal must be received by the exchange agent prior to the deadline described above at its address set forth under "—Exchange Agent" in this prospectus. The withdrawal notice must:

•

specify the name of the person who tendered the old notes to be withdrawn;



•

must contain a description of the old notes to be withdrawn, the certificate numbers shown on the particular certificates evidencing such old notes and the aggregate principal amount represented by such old notes; and



•

must be signed by the holder of those old notes in the same manner as the original signature on the letter of transmittal, including any required signature guarantees, or be accompanied by evidence satisfactory to us that the person withdrawing the tender has succeeded to the beneficial ownership of the old notes. In addition, the notice of withdrawal must specify, in the case of old notes tendered by delivery of certificates for such old notes, the name of the registered holder, if different from that of the tendering holder or, in the case of old notes tendered by book-entry transfer, the name and number of the account at DTC to be credited with the withdrawn old notes. The signature on the notice of withdrawal must be guaranteed by an eligible institution unless the old notes have been tendered for the account of an eligible institution.

44

---

Table of Contents

        Withdrawal of tenders of old notes may not be rescinded, and any old notes properly withdrawn will be deemed not validly tendered for purposes of this exchange offer. Properly withdrawn old notes may, however, be retendered by again following one of the procedures described in "—Procedures for Tendering" prior to the expiration date.

Exchange Agent

        U.S. Bank National Association has been appointed the exchange agent for this exchange offer. Letters of transmittal and all correspondence in connection with this exchange offer should be sent or delivered by each holder of old notes, or a beneficial owner's commercial bank, broker, dealer, trust company or other nominee, to the exchange agent as follows:

        We will pay the exchange agent reasonable and customary fees for its services and will reimburse it for its reasonable, out-of-pocket expenses in connection with this exchange offer.

Fees and Expenses

        We will bear the expenses of soliciting tenders. The principal solicitation is being made by mail. However, we may make additional solicitations by telegraph, telephone or in person by our officers and regular employees and those of our affiliates.

        We have not retained any dealer-manager in connection with the exchange offer and will not make any payments to broker-dealers or others soliciting acceptances of the exchange offer. We may, however, pay the exchange agent reasonable and customary fees for its services and reimburse it for its related reasonable out-of-pocket expenses. We will pay the other cash expenses incurred in connection with the exchange offer.

Transfer Taxes

        We will pay all transfer taxes, if any, applicable to the exchange of old notes under the exchange offer. The tendering holder, however, will be required to pay any transfer taxes, whether imposed on the registered holder or any other person, if:

•

new notes are to be delivered to, or issued in the name of, any person other than the registered holder of the old notes so exchanged,



•

tendered old notes are registered in the name of any person other than the person signing the letter of transmittal, or



•

a transfer tax is imposed for any reason other than the exchange of old notes under the exchange offer.

        If satisfactory evidence of payment of transfer taxes is not submitted with the letter of transmittal, the amount of any transfer taxes will be billed to the tendering holder.

45

Table of Contents

Accounting Treatment

        We will record the new notes at the same carrying value as the old notes as reflected in our accounting records on the date of the exchange. Accordingly, we will not recognize any gain or loss for accounting purposes upon completion of the exchange offer.

Consequences of Failure to Tender

        All untendered old notes will remain subject to the restrictions on transfer provided for in the old notes and in the indenture. The old notes that are not exchanged for new notes pursuant to the exchange offer will remain restricted securities. Accordingly, such old notes may be resold only:

•

to us (upon redemption thereof or otherwise),



•

pursuant to a registration statement which has been declared effective under the Securities Act,



•

for so long as the old notes are eligible for resale pursuant to Rule l44A, to a person the holder of the old notes and any person acting on its behalf reasonably believes is a "qualified institutional buyer" as defined in Rule l44A, that purchases for its own account or for the account of another qualified institutional buyer, in each case to whom notice is given that the transfer is being made in reliance on Rule l44A, or



•

pursuant to any other available exemption from the registration requirements of the Securities Act (in which case we and the trustee shall have the right to require the delivery of an opinion of counsel, certifications and/or other information satisfactory to us and the trustee),

in each case subject to compliance with any applicable foreign, state or other securities laws.

        Upon completion of the exchange offer, due to the restrictions on transfer of the old notes and the absence of such restrictions applicable to the new notes, it is likely that the market, if any, for old notes will be relatively less liquid than the market for new notes. Consequently, holders of old notes who do not participate in the exchange offer could experience significant diminution in the value of their old notes, compared to the value of the new notes. The holders of old notes not tendered will have no further registration rights, except that, under limited circumstances, we may be required to file a shelf registration statement for a continuous offer of old notes.

Information Regarding the Registration Rights Agreement

        As noted above, we are effecting the exchange offer to comply with the registration rights agreement. The registration rights agreement requires us to:

•

cause to be filed within 180 days after June 16, 2010 an exchange offer registration statement with the SEC,



•

use our reasonable best efforts to cause the exchange offer registration statement to become effective as soon as practicable, but in no event later than 270 days after June 16, 2010;



•

use our reasonable best efforts to consummate the exchange offer not later than 30 days after the 270^th day after June 16, 2010; and



•

cause to be filed a shelf registration statement for the resale of the old notes under certain circumstances and to use our reasonable best efforts to cause such registration statement to become effective under the Securities Act.

        The requirements described in the first three bullets above under the registration rights agreement will be satisfied when we complete the exchange offer.

46

Table of Contents

        In the event that:

•

the registration statement is not filed with the SEC on or prior to the 180^th day after June 16, 2010,



•

the registration statement has not been declared effective by the SEC on or prior to the 270^th day after June 16, 2010, or



•

the exchange offer is not completed or the shelf registration statement, if required, has not become effective on or prior to the 300^th day after June 16, 2010 (or, under certain circumstances, within 90 days of a request to file a shelf registration statement),

the interest rate on the old notes will be increased by a rate of 0.25% per annum during the 90-day period following such registration default and shall increase by 0.25% per annum at the end of each subsequent 90-day period, but in no event shall such increase exceed 1.00% per annum. Following the cure of all such registration defaults, the accrual of additional interest shall cease and the interest rate will be reduced to the original interest rate borne by the old notes.

        Under the registration rights agreement, we have also agreed to keep the registration statement for the exchange offer effective for not less than 30 calendar days (or longer, if required by applicable law) after the date on which notice of the exchange offer is mailed to holders.

        Our obligations to register the new notes will terminate upon the completion of the exchange offer. However, under certain circumstances specified in the registration rights agreement, we may be required to file a shelf registration statement for a continuous offer in connection with the old notes.

        This summary includes only the material terms of the registration rights agreement. For a full description, you should refer to the complete copy of the registration rights agreement, which has been filed as an exhibit to the registration statement relating to the exchange offer and the new notes. See "Where You Can Find More Information."

USE OF PROCEEDS

        This exchange offer is intended to satisfy our obligations under the registration rights agreement into which we entered when we issued the old notes. We will not receive any cash proceeds from this exchange offer. In exchange for the old notes that you tender pursuant to this exchange offer, you will receive new notes in like principal amount. The old notes that are surrendered in exchange for the new notes will be retired and cancelled by us upon receipt and cannot be reissued. The issuance of the new notes under this exchange offer will not result in any increase in our outstanding indebtedness. We will pay all expenses incident to the exchange offer.

RATIO OF EARNINGS TO FIXED CHARGES

THE VOUGHT ACQUISITION

        On June 16, 2010, we completed our previously announced acquisition of Vought pursuant to the Merger Agreement. Pursuant to the Merger Agreement, (i) Merger Sub was merged with and into Vought and (ii) then Vought was merged with and into Triumph Aerostructures, LLC, our direct wholly owned limited liability company subsidiary, with Triumph Aerostructures, LLC as the surviving entity in the mergers. The consideration for the Vought Acquisition consisted of $547.9 million in cash and 7,496,165 shares of our common stock. We also discharged, repaid or otherwise retired approximately $603.1 million of Vought's existing indebtedness, which represented substantially all of Vought's outstanding indebtedness.

        As a result of the Vought Acquisition, the Carlyle equity funds own approximately 31% of our outstanding common stock. In connection with the merger, we also entered into a stockholders agreement with the Carlyle equity funds and Carlyle, pursuant to which, on June 16, 2010, we increased the size of our board of directors from six directors to nine and appointed Adam Palmer, Elmer Doty and Ralph Eberhart to our board of directors. The Carlyle equity funds are entitled to designate three persons to our board of directors until they no longer hold 66.67% of the shares that they received in the merger; they are entitled to designate two persons to our board of directors until they no longer hold 33.33% of the shares that they received in the merger; and they are entitled to designate one person to our board of directors as long as they own at least 5% of our outstanding common stock. The Carlyle equity funds may not transfer or hedge any shares of our common stock that they received in the merger for one year following the closing, and after this period the Carlyle equity funds will be prohibited from making transfers to certain large holders of our common stock. The Carlyle equity funds, Carlyle and investment funds managed by each of them have also agreed to customary standstill restrictions which prohibit them from acquiring additional shares of our common stock and taking certain other actions to seek to gain control of Triumph without our prior written consent. These restrictions survive until the later of (i) the date on which there are no Carlyle-designated directors on our board and (ii) the date on which the Carlyle equity funds and their affiliates own less than 10% of our outstanding common stock. In addition, for two years following the closing, Carlyle has agreed to certain non-competition restrictions with respect to business activities conducted by Vought. From the closing until December 31, 2011, Carlyle has agreed that it will not solicit for employment or employ specified members of Vought's senior management team. We have also granted the Carlyle equity funds demand and piggy-back registration rights, which commence after the one-year transfer restriction period expires.

        We funded the Vought Acquisition through cash on hand and the following activities:

•

the issuance of 7,496,165 shares of our common stock to the Vought stockholders;



•

the issuance by the Company of $350,000,000 aggregate principal amount of old notes at a price equal to 99.27% of the face value;



•

the borrowing by the Company of $350,000,000 principal amount under the Term Loan Facility at a price equal to 99.5% of the face value; and



•

the borrowing by the Company of $128,300,000, drawn under the Revolving Credit Facility.

Term Loan Facility

        Simultaneously with the closing of the Vought Acquisition, we entered into the Term Loan Facility, which is a six-year term loan facility in an aggregate principal amount equal to $350.0 million at a price equal to 99.5% of the face value, with principal repayable in quarterly installments at a rate of 1.00% per year, with the balance payable on the final maturity date. Borrowings under the new senior secured term loan facility bear interest, at our option, at either the base rate (the highest of the prime rate announced by Royal Bank of Canada, the administrative agent to the facility, the federal funds effective

rate plus 0.50%, or the Eurodollar Rate (adjusted for certain reserve requirements) for a Eurodollar loan with a one-month interest period plus 1.00%) plus an applicable margin or at the rate which Eurodollar deposits for one, two, three or six months appear on the Reuters Screen LIBOR01 Page (adjusted for certain reserve requirements), which is referred to as the "Eurodollar Rate," plus an applicable margin. Notwithstanding the foregoing, the minimum base rate is 2.5% and the minimum Eurodollar Rate (before giving effect to any adjustment for reserve requirements) is 1.5%. See "Description of Certain Indebtedness."

Revolving Credit Facility

        On May 10, 2010, we entered into the Revolving Credit Facility, a revolving credit facility in the aggregate principal amount of $535.0 million, to expire and be repaid in full by the fourth anniversary of the closing date of the Vought Acquisition. Borrowings under the Revolving Credit Facility bear interest, at our option, at either the base rate plus an applicable margin or the Eurodollar Rate plus an applicable margin. The Revolving Credit Facility replaced and refinanced our 2009 Credit Facility. See "Description of Certain Indebtedness."

UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

        The unaudited pro forma condensed combined financial information of Triumph is presented to show how Triumph might have looked if the Vought Acquisition had occurred on the dates and for the periods indicated below. The following unaudited pro forma condensed combined financial information has been derived by applying pro forma adjustments to the historical consolidated financial statements of Triumph and Vought. The unaudited pro forma condensed combined statement of income for the fiscal year ended March 31, 2010 gives effect to the Vought Acquisition as if it had occurred on April 1, 2009 and combines Triumph's audited consolidated statement of income for the fiscal year ended March 31, 2010 with Vought's unaudited consolidated statement of income for the twelve-month period ended March 28, 2010. Vought's unaudited consolidated statement of income for the twelve-month period ended March 28, 2010 has been prepared by adding the financial data from Vought's unaudited consolidated income statement for the three months ended March 28, 2010 to the results from Vought's audited consolidated income statement for the fiscal year ended December 31, 2009 and deducting the financial data from Vought's unaudited consolidated income statement from the three months ended March 29, 2009.

        The unaudited pro forma condensed combined statement of income for the three months ended June 30, 2010 assumes that the acquisition took place on April 1, 2010. Triumph's unaudited statement of income for the three months ended June 30, 2010 has been combined with Vought's unaudited statement of income for the period from April 1, 2010 through June 15, 2010. Triumph's unaudited statement of income for the three months ended June 30, 2010, includes the results of Vought from June 16, 2010.

        The historical consolidated financial information of Triumph and Vought has been adjusted in the unaudited pro forma condensed combined financial statements to give effect to pro forma events that are (1) directly attributable to the Vought Acquisition, (2) factually supportable and (3) with respect to the statements of income, expected to have a continuing impact on the combined results. The unaudited pro forma condensed combined financial information should be read in conjunction with the accompanying notes to the unaudited pro forma condensed combined financial statements. All pro forma adjustments and their underlying assumptions are described more fully in the notes to the unaudited pro forma condensed combined financial statements. In addition, the unaudited condensed combined financial information should be read in conjunction with the following historical consolidated financial statements and accompanying notes of Triumph and Vought for the applicable periods:

•

Separate historical financial statements of Triumph as of and for the fiscal year ended March 31, 2010 and the related notes included in the Annual Report on Form 10-K filed on May 14, 2010;



•

Separate historical financials statements of Vought as of and for the year ended December 31, 2009 and the related notes thereto, included in Exhibit 99.2 to the Current Report on Form 8-K filed on June 22, 2010;



•

Separate historical unaudited interim consolidated balance sheet of Vought as of March 28, 2010, and the unaudited consolidated statement of operations for the three months ended March 28, 2010, and March 28, 2009, and the notes related thereto, included in Exhibit 99.3 to the Current Report on Form 8-K filed on June 22, 2010; and



•

Separate historical financial statements of Triumph as of and for the three months ended June 30, 2010 and the related note includes in Triumph's Quarterly Report on Form 10-Q for the period ended June 30, 2010.

        The unaudited pro forma condensed combined financial information has been presented for informational purposes only. The pro forma information is not necessarily indicative of what Triumph's financial position or results of operations actually would have been had the Vought Acquisition been completed as of the dates indicated. In addition, the unaudited pro forma condensed combined

financial information does not purport to project the future financial position or operating results of Triumph. All material accounts and transactions between Triumph and Vought have been eliminated from the unaudited pro forma condensed combined financial statements. The unaudited pro forma condensed combined financial statements do not include pro forma adjustments for Triumph's February 2010 acquisition of Fabritech, Inc.

        The unaudited pro forma condensed combined financial information has been prepared using the acquisition method of accounting under existing GAAP. Triumph has been treated as the acquirer in the Vought Acquisition for accounting purposes, and the total purchase price of the Vought Acquisition, including related fees and expenses, has been allocated to Triumph's net assets based upon Triumph's preliminary estimates of fair value. The pro forma information presented, including allocations of purchase price, has been prepared based on preliminary estimates using information available as of the date of this filing. The final allocation of the total purchase price to Vought's net assets will be based on a formal valuation of the fair value of Vought's net assets that existed as of the closing date of the Vought Acquisition. Differences between Triumph's preliminary estimates (for example, estimates as to fair value of acquired property, plant and equipment as well as intangible assets) presented in the accompanying unaudited pro forma condensed combined financial statements and the final acquisition accounting for such items will occur and these differences could be material and could have a material impact on Triumph's future results of operations and financial position.

        The unaudited pro forma combined financial information does not reflect any cost savings, operating synergies or revenue enhancements that Triumph may achieve as a result of the Vought Acquisition or the costs to combine the operations of Triumph and Vought or the costs necessary to achieve these cost savings, operating synergies and revenue enhancements.

COMBINED FINANCIAL STATEMENTS

1. DESCRIPTION OF TRANSACTION

        On June 16, 2010, Triumph Group, Inc. ("Triumph") completed its previously-announced acquisition of Vought Aircraft Industries, Inc. ("Vought"), pursuant to an Agreement and Plan of Merger, dated March 23, 2010 (the "Merger Agreement"). Upon completion of the transactions contemplated by the Merger Agreement, Vought became a wholly owned subsidiary of Triumph (the "Vought Acquisition"). Upon completion of the Vought Acquisition, holders of Vought common stock and equity awards received, in the aggregate, $547.9 million in cash and 7,496,165 shares of Triumph common stock.

        At the effective time of the Vought Acquisition, each outstanding option to purchase shares of Vought common stock and each stock appreciation right in respect of Vought common stock granted under the 2001 Vought Stock Option Plan and the 2006 Vought Incentive Award Plan, whether or not exercisable, vested in full and was cancelled, and holders of such options and stock appreciation rights received an amount in cash equal to the excess, if any, of approximately $34.847 over the per share exercise price for each share subject to the option or stock appreciation right, less required withholding taxes.

        At the effective time of the Vought Acquisition, each Vought restricted stock unit granted under the 2006 Vought Incentive Award Plan became fully vested and was converted into the right to receive an amount in cash equal to approximately $34.847 per share, less required withholding taxes.

2. BASIS OF PRESENTATION AND ORGANIZATION

        The accompanying unaudited pro forma condensed combined financial information was prepared using the acquisition method of accounting and was based on the historical financial statements of Triumph and Vought. For ease of reference, all pro forma statements use Triumph's period end dates and Vought's reported information has been recast accordingly to correspond to Triumph's period end dates by adding Vought's comparable quarterly periods as necessary.

        The acquisition method of accounting is based on Accounting Standards Codification (ASC) Topic 805, Business Combinations, which Triumph adopted on April 1, 2009 and used the fair value concepts defined in ASC Topic 820, Fair Value Measurements and Disclosures, which Triumph has adopted as required.

        ASC Topic 805, requires, among other things, that most assets acquired and liabilities assumed be recognized at their fair values as of the acquisition date. Financial statements of Triumph issued after completion of the Vought Acquisition will reflect such fair values, measured as of the acquisition date, which may be different than the estimated fair values included in these unaudited pro forma condensed combined financial statements. The financial statements of Triumph issued after the completion of the Vought Acquisition will not be retroactively restated to reflect the historical financial position or results of operations of Vought. In addition, ASC Topic 805 establishes that the consideration transferred be measured at the closing date of the Vought Acquisition at the then-current market price, which has been reflected in these unaudited pro forma condensed combined financial statements.

        ASC Topic 820, defines the term "fair value" and sets forth the valuation requirements for any asset or liability measured at fair value, expands related disclosure requirements and specifies a hierarchy of valuation techniques based on the nature of the inputs used to develop the fair value measures. Fair value is defined as "the price that would be received to sell and asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date." This is an

56

Table of Contents

COMBINED FINANCIAL STATEMENTS (Continued)

2. BASIS OF PRESENTATION AND ORGANIZATION (Continued)

exit price concept for valuation of the asset or liability. In addition, market participants are assumed to be unrelated (to Triumph) buyers and sellers in the principal (or the most advantageous) market for the asset or liability. Fair value measurements for an asset assume the highest and best use by these market participants. As a result of these standards, Triumph may be required to record assets which are not intended to be used or sold and/or to value assets at fair value measures that do not reflect Triumph's intended use of those assets. Many of these fair value measurements can be highly subjective and it is also possible that other professionals, applying reasonable judgment to the same facts and circumstances, could develop and support a range of alternative estimated amounts.

        Under ASC Topic 805, acquisition-related transaction costs (i.e., advisory, legal, other professional fees, etc.) and certain acquisition-related restructuring charges impacting the target company are not included as a component of consideration transferred, but are accounted for as expenses in the periods in which the costs are incurred. Total advisory, legal, regulatory and valuation costs incurred by Triumph were approximately $40.5 million, of which $1.1 million was expensed during the fiscal year ended March 31, 2010, $17.4 million was expensed during the three months ended June 30, 2010 and the remainder is being capitalized as deferred financing costs. The unaudited pro forma condensed combined financial statements do not reflect restructuring charges expected to be incurred in connection with the Vought Acquisition.

3. ACCOUNTING POLICIES

        Triumph has identified certain differences in accounting policies between Triumph and Vought, including financial statement classification and inventory capitalization policies and has made pro forma adjustments, as presented herein, for these policies. At this time, Triumph is not aware of any differences in accounting policies that would have a material impact on the combined financial statements, and the unaudited pro forma condensed combined financial statements do not assume any other differences in accounting policies. Now that the Vought Acquisition has been completed, Triumph will perform a detailed review of Vought's accounting policies. As a result of that review, Triumph may identify additional differences between the accounting policies of the two companies that, when conformed, could have a material impact on the combined financial statements.

4. CONSIDERATION TRANSFERRED

        The following is a preliminary estimate of consideration transferred to effect the acquisition of Vought:

NOTES TO THE UNAUDITED PRO FORMA CONDENSED

COMBINED FINANCIAL STATEMENTS (Continued)

4. CONSIDERATION TRANSFERRED (Continued)

        The price of Triumph common stock used to measure consideration transferred was $67.35, the closing stock price of Triumph on June 15, 2010.

5. ESTIMATES OF THE ASSETS ACQUIRED AND LIABILITIES ASSUMED

        The following is a preliminary estimate of the assets acquired and the liabilities assumed by Triumph in the Vought Acquisition, reconciled to the estimate of consideration transferred:

        The purchase price allocation for purposes of these unaudited pro forma condensed combined financial statements was primarily limited to the identification and valuation of intangible assets. Triumph believes this was an appropriate approach based on review of similar type acquisitions, which appeared to indicate that the most significant and material portion of the purchase price would be allocated to intangible assets.

        The following is a discussion of the adjustments made to Vought's assets and liabilities in connection with the preparation of these unaudited pro forma condensed combined financial statements:

        Property & equipment:    As of the effective time of the Vought Acquisition, property & equipment is required to be measured at fair value, unless those assets are classified as held-for-sale on the acquisition date. The acquired assets can include assets that are not intended to be used or sold, or that are intended to be used in a manner other than their highest and best use. Triumph does not have sufficient information at this time as to the specific types, nature, age, condition or location of these assets. In addition, more information is needed regarding the nature and types of machinery and equipment, which is the majority of Vought's property & equipment balance, in order to assess these assets against current technology products, costs and values. All of these elements can cause differences between fair value and net book value. For purposes of these unaudited pro forma condensed combined financial statements, Triumph considered other comparable acquisition transactions and

58

Table of Contents

NOTES TO THE UNAUDITED PRO FORMA CONDENSED

COMBINED FINANCIAL STATEMENTS (Continued)

5. ESTIMATES OF THE ASSETS ACQUIRED AND LIABILITIES ASSUMED (Continued)

estimated that the fair value adjustment to increase property and equipment would approximate $100 million. The estimate of fair value is preliminary and subject to change and could vary materially from the actual adjustment on the closing date. The estimated remaining weighted average useful life of the underlying assets is estimated to be 10 years. A 20% change in the valuation of property and equipment would cause an increase or decrease to annual depreciation expense of approximately $5.5 million ($1.4 million per quarter), assuming a weighted average useful life of 10 years.

        Intangibles assets:    As of the effective time of the Vought Acquisition, intangible assets are required to be measured at fair value and these acquired assets could include assets that are not intended to be used or sold or that are intended to be used in a manner other than their highest and best use. For purposes of these unaudited pro forma condensed combined financial statements, it is assumed that all assets will be used and be used in a manner that represents their highest and best use. Based on internal assessments as well as discussions with Vought and external third-party valuation advisors, Triumph has identified the following significant intangible assets: customer relationships/contracts, and the Vought tradename.

        The fair value of these intangible assets is normally determined primarily through the use of the "income approach," which requires an estimate or forecast of all the expected future cash flows either through the use of either the multi-period excess earnings method or relief-from-royalty method.

        At this time, Triumph does not have sufficient information as to the amount, timing and risk of the estimated cash flows needed to value the customer relationship/contracts and the Vought tradename. Some of the more significant assumptions inherent in the development of estimated cash flows, from the perspective of a market participant, include: the amount and timing of projected future cash flows (including net sales, costs of sales, selling, general and administrative expenses and working capital/contributory asset charges) and the discount rate selected to measure the risk inherent in the future cash flows. However, for purposes of these unaudited pro forma condensed combined financial statements, using currently available information, such as Vought's historical and projected revenues, customer attrition rates, cost structure, and certain other high-level assumptions, the fair value of the customer relationship/contracts and the Vought tradename were estimated by external third party valuation advisors and reviewed by Triumph management and were as follows: Customer relationship/contracts—$230.0 million with a weighted average useful life of 15.8 years; and the Vought tradename—$634.0 million with an indefinite life.

        These preliminary estimates of fair value and weighted-average useful life will likely be different from the final acquisition accounting, and the difference could have a material impact on the accompanying unaudited pro forma condensed combined financial statements. Once Triumph and its third-party valuation advisors have full access to the specifics of the Vought intangible assets, additional insight will be gained that could impact: (i) the estimated total value assigned to intangible assets, (ii) the estimated allocation of value between finite-lived and indefinite-lived intangible assets and/or (iii) the estimated weighted-average useful life of each category of intangible assets. The estimated intangible asset values and their useful lives could be impacted by a variety of factors that may become known to us only upon access to additional information and/or by changes in such factors that may occur prior to the effective time of the Vought Acquisition. A 20% change in the valuation of definite lived intangible assets would cause a corresponding increase or decrease to annual amortization expense of approximately $4.6 million ($1.2 million per quarter), assuming a weighted-average useful

life of 10 years. The estimated intangible asset values and their useful lives could be impacted by a variety of factors that may become known to Triumph only upon access to additional information.

        Goodwill:    Goodwill is calculated as the difference between the acquisition date fair value of the estimated consideration transferred and the values assigned to the assets acquired and liabilities assumed. Goodwill is not amortized but rather subject to an annual impairment test.

6. RECLASSIFICATIONS

        Certain reclassification adjustments have been made to the historical financial statements of Vought to conform to Triumph's presentation as follows:

(1)

Certain selling, general and administrative costs that Triumph classifies as selling, general and administrative expenses; and depreciation and amortization expenses that Triumph classifies separately are included in Cost of Sales on Vought's statements of income. This adjustment reclassifies Vought's historical Cost of Sales and Selling, General & Administrative to the respective captions presented in Triumph's historical statements of income.

TRIUMPH MANAGEMENT'S DISCUSSION AND ANALYSIS OF
TRIUMPH'S FINANCIAL CONDITION AND RESULTS OF OPERATIONS

        The following discussion contains Triumph management's discussion and analysis of financial condition and results of operations for Triumph and should be read in conjunction with Triumph's consolidated financial statements and the related notes.

Overview

        We are a major supplier to the aerospace industry and have two operating segments: (i) Triumph Aerospace Systems Group, whose companies design, engineer, manufacture and sell a wide range of proprietary and build-to-print components, assemblies and systems for the global aerospace OEM market; and (ii) Triumph Aftermarket Services Group, whose companies serve aircraft fleets, notably commercial airlines, the U.S. military and cargo carriers, through the maintenance, repair and overhaul of aircraft components and accessories manufactured by third parties.

        On June 16, 2010, we announced the completion of the Vought Acquisition. The acquired business is operating as Triumph Aerostructures-Vought Commercial Division and Triumph Aerostructures-Vought Integrated Programs Division.

        Financial highlights for the first quarter of the fiscal year ending March 31, 2011 include:

•

Net sales for the first quarter of the fiscal year ending March 31, 2011 increased 28.5% to $406.4 million, including 2.1% increase due to organic growth.



•

Operating income in the first quarter of fiscal 2011 decreased 13.3% to $32.9 million, which included $17.4 million of acquisition-related expenses associated with the Vought Acquisition.



•

Income from continuing operations for the first quarter of fiscal 2011 decreased 46.2% to $11.6 million, due to the acquisition-related expenses associated with the Vought Acquisition.



•

Backlog increased to $3.3 billion due to the Vought Acquisition, having an organic increase of 1% from the prior year, but an organic decrease of 1% sequentially from the prior quarter.



•

Income from continuing operations was $0.62 per diluted common share, which included the effect of $0.71 per diluted share for acquisition-related expenses associated with the Vought Acquisition.



•

We generated $22.7 million of cash flow from operating activities.

        Financial highlights for the fiscal year ended March 31, 2010 include:

•

Net sales for fiscal 2010 increased 4.4% to $1.29 billion.



•

Operating income in fiscal 2010 increased 2.2% to $155.3 million.



•

Net income for fiscal 2010 decreased 23.0% to $67.8 million.



•

Backlog decreased 1.0% over the prior year to $1.3 billion.

        For the fiscal year ended March 31, 2010, net sales totaled $1.29 billion, a 4.4% increase from fiscal year 2009 net sales of $1.24 billion. Net income for fiscal year 2010 decreased 23.0% to $67.8 million, or $4.07 per diluted common share, versus $88.0 million, or $5.30 per diluted common share, for fiscal year 2009. As discussed in further detail below under "Results of Operations," the decrease in net income is attributable to the write-down of the carrying value of our discontinued operation to estimated fair value less cost to sell, as well as the additional interest expense associated with the issuance of our 8% Senior Subordinated Notes due 2017 in November 2009, offset by the contribution from recent acquisitions.

65

Table of Contents

        Our working capital needs are generally funded through cash flows from operations and borrowings under our credit arrangements. For the fiscal year ended March 31, 2010, we generated approximately $169.6 million of cash flows from operating activities, used approximately $62.5 million in investing activities and generated approximately $35.3 million in financing activities.

        We continue to remain focused on growing our core businesses as well as growing through strategic acquisitions. Our organic sales declined in fiscal 2010 due to major program delays, the dramatic decline in the regional and business jet markets due to the overall economy, lower passenger and freight traffic and airline inventory de-stocking. Our Company has an aggressive but selective acquisition approach that adds capabilities and increases our capacity for strong and consistent internal growth.

        In the fourth quarter of fiscal 2010, we acquired Fabritech, Inc. (now Triumph Fabrications—St. Louis) and DCL Avionics, Inc. (now part of Triumph Instruments—Burbank), collectively, the "fiscal 2010 acquisitions." The results of Triumph Fabrications—St. Louis are included in the Company's Aftermarket Services Segment from the date of acquisition.

        In March 2009, we acquired Merritt Tool Company, Inc. (now Triumph Structures—East Texas), Saygrove Defence & Aerospace Group Limited (now Triumph Actuation & Motion Control Systems—UK), the aviation segment of Kongsberg Automotive Holdings ASA (now Triumph Controls—U.K and Triumph Controls—Germany) and The Mexmil Company, LLC (now Triumph Insulation Systems), collectively, the "fiscal 2009 acquisitions." The results for the fiscal 2009 acquisitions are included in the Company's Aerospace Systems Segment.

Results of Operations

        The following includes a discussion of our consolidated and business segment results of operations. The Company's diverse structure and customer base do not provide for precise comparisons of the impact of price and volume changes to our results. However, we have disclosed the significant variances between the respective periods.

Non-GAAP Financial Measures

        We prepare and publicly release quarterly unaudited financial statements prepared in accordance with GAAP. In accordance with recent SEC guidance on Compliance and Disclosure Interpretations, we also disclose and discuss certain non-GAAP financial measures in our public releases. Currently, the non-GAAP financial measures that we disclose are EBITDA, which is our income from continuing operations before interest, income taxes, depreciation and amortization, and Adjusted EBITDA, which is EBITDA adjusted for acquisition related costs associated with the Vought Acquisition. We disclose EBITDA and Adjusted EBITDA on a consolidated and an operating segment basis in our earnings releases, investor conference calls and filings with the SEC. The non-GAAP financial measures that we use may not be comparable to similarly titled measures reported by other companies. Also, in the future, we may disclose different non-GAAP financial measures in order to help our investors more meaningfully evaluate and compare our future results of operations to our previously reported results of operations.

        We view EBITDA as an operating performance measure and as such we believe that the GAAP financial measure most directly comparable to it is income from continuing operations. In calculating EBITDA, we exclude from income from continuing operations the financial items that we believe should be separately identified to provide additional analysis of the financial components of the day-to-day operation of our business. We have outlined below the type and scope of these exclusions and the material limitations on the use of these non-GAAP financial measures as a result of these exclusions. EBITDA is not a measurement of financial performance under GAAP and should not be considered as a measure of liquidity, as an alternative to net income (loss), income from continuing operations, or as

an indicator of any other measure of performance derived in accordance with GAAP. Investors and potential investors in our securities should not rely on EBITDA as a substitute for any GAAP financial measure, including net income (loss) or income from continuing operations. In addition, we urge investors and potential investors in our securities to carefully review the reconciliation of EBITDA to income from continuing operations set forth below, in our earnings releases and in other filings with the SEC and to carefully review the GAAP financial information included as part of our Quarterly Reports on Form 10-Q and our Annual Reports on Form 10-K that are filed with the SEC, as well as our quarterly earnings releases, and compare the GAAP financial information with our EBITDA.

        EBITDA is used by management to internally measure our operating and management performance and by investors as a supplemental financial measure to evaluate the performance of our business that, when viewed with our GAAP results and the accompanying reconciliation, we believe provides additional information that is useful to gain an understanding of the factors and trends affecting our business. We have spent more than 15 years expanding our product and service capabilities partially through acquisitions of complementary businesses. Due to the expansion of our operations, which included acquisitions, our income from continuing operations has included significant charges for depreciation and amortization. EBITDA excludes these charges and provides meaningful information about the operating performance of our business, apart from charges for depreciation and amortization. We believe the disclosure of EBITDA helps investors meaningfully evaluate and compare our performance from quarter to quarter and from year to year. We also believe EBITDA is a measure of our ongoing operating performance because the isolation of non-cash charges, such as depreciation and amortization, and non-operating items, such as interest and income taxes, provides additional information about our cost structure, and, over time, helps track our operating progress. In addition, investors, securities analysts and others have regularly relied on EBITDA to provide a financial measure by which to compare our operating performance against that of other companies in our industry.

        Set forth below are descriptions of the financial items that have been excluded from our income from continuing operations to calculate EBITDA and the material limitations associated with using this non-GAAP financial measure as compared to income from continuing operations:

•

Amortization expense may be useful for investors to consider because it represents the estimated attrition of our acquired customer base and the diminishing value of product rights and licenses. We do not believe these charges necessarily reflect the current and ongoing cash charges related to our operating cost structure.



•

Depreciation may be useful for investors to consider because it generally represents the wear and tear on our property and equipment used in our operations. We do not believe these charges necessarily reflect the current and ongoing cash charges related to our operating cost structure.



•

The amount of interest expense and other we incur may be useful for investors to consider and may result in current cash inflows or outflows. However, we do not consider the amount of interest expense and other to be a representative component of the day-to-day operating performance of our business.



•

Income tax expense may be useful for investors to consider because it generally represents the taxes which may be payable for the period and the change in deferred income taxes during the period and may reduce the amount of funds otherwise available for use in our business. However, we do not consider the amount of income tax expense to be a representative component of the day-to-day operating performance of our business.
