NON-GAAP FINANCIAL MEASURES

We prepare and publicly release quarterly unaudited financial statements prepared in accordance with U.S. GAAP. In accordance with SEC guidance on Compliance and Disclosure Interpretations, we also disclose and discuss certain non-GAAP financial measures in our public releases. The non-GAAP financial measure that we disclose is Adjusted EBITDA (as reported), which is net income before interest, income taxes, amortization of acquired contract liabilities, curtailments and early retirement incentives, legal settlements, loss on divestitures and depreciation and amortization. We disclose Adjusted EBITDA on a consolidated and a reportable 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 Adjusted EBITDA as an operating performance measure and, as such, we believe that the U.S. GAAP financial measure most directly comparable to it is net income. In calculating Adjusted EBITDA, we exclude from net income 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. Adjusted EBITDA is not a measurement of financial performance under U.S. GAAP and should not be considered as a measure of liquidity, as an alternative to net income (loss), net income, or as an indicator of any other measure of performance derived in accordance with U.S. GAAP. Investors and potential investors in our securities should not rely on Adjusted EBITDA as a substitute for any U.S. GAAP financial measure, including net income (loss) or net income. In addition, we urge investors and potential investors in our securities to carefully review the reconciliation of Adjusted EBITDA to net income set forth under "Summary—Summary historical consolidated financial data," in our earnings releases and in other filings with the SEC and to carefully review the U.S. 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 Adjusted EBITDA.

Adjusted 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 U.S. 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 20 years expanding our product and service capabilities, partially through acquisitions of complementary businesses. Due to the expansion of our operations, which included acquisitions, our net income has included significant charges for depreciation and amortization. Adjusted 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 Adjusted EBITDA helps investors meaningfully evaluate and compare our performance from quarter to quarter and from year to year. We also believe Adjusted 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 Adjusted EBITDA to provide a financial measure by which to compare our operating performance against that of other companies in our industry.

Table of Contents

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

•: Curtailments and early retirement incentives may be useful for investors to consider because they represent the current period impact of the change in the defined benefit obligation due to the reduction in future service costs as well as the incremental cost of retirement incentive benefits paid to participants. We do not believe these earnings necessarily reflect the current and ongoing cash earnings related to our operations.
•: Legal settlements may be useful for investors to consider because it reflects gains or losses from disputes with third parties. We do not believe these earnings necessarily reflect the current and ongoing cash earnings related to our operations.
•: Amortization of acquired contract liabilities may be useful for investors to consider because it represents the non-cash earnings on the fair value of off-market contracts acquired through acquisitions. We do not believe these earnings necessarily reflect the current and ongoing cash earnings related to our operations.
•: Amortization expense (including intangible asset impairments) 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.
•: Divestitures may be useful for investors to consider because they reflect gains or losses from sale of operating units. We do not believe these earnings necessarily reflect the current and ongoing cash earnings related to our operations.
•: 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.

In addition, in this offer to exchange, Adjusted EBITDA (as further adjusted) has been further adjusted to exclude certain items we are permitted to add back in our calculation of consolidated EBITDA for purposes of complying with the covenants under our revolving credit facility, including the impact of cash and non-cash restructuring charges, including termination benefits, facility closure and other exit costs, and disruption costs.

Management compensates for the above-described limitations of using non-GAAP measures only to supplement our U.S. GAAP results and to provide additional information that is useful to gain an understanding of the factors and trends affecting our business.

For the twelve month period ended September 30, 2017, 57% of our net sales were into the commercial aerospace market, while the military market represented 21% of our net sales and business jet, regional jet and other markets represented 22% of our net sales.

Table of Contents

Broad array of products and services. We offer the ability to design, fabricate or overhaul virtually any type of part, component or assembly. This breadth of experience and capabilities makes Triumph unique among aerospace industry suppliers. We believe providing aerospace customers with a single point of purchase for a diverse array of technically complex products and services for a wide range of aerospace platforms and programs, gives us a competitive advantage in developing strategic partnerships with OEMs. We design, engineer and manufacture aircraft components to meet our customers' particular requirements—from single components to complex aerostructures and their contents. 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 aftermarket repair and overhaul services on various aviation components manufactured by third parties. This business continues to expand in response to increasing passenger miles, aging fleets, and the trend toward consolidation and outsourcing among commercial airlines. We are experienced in all major aerospace markets—commercial, military, business jets and regional jets; unmanned vehicles and rotorcraft. Our success on these and other legacy programs provides us with a strong foundation and positions us for future growth on new commercial programs.

Advanced manufacturing and technical capabilities. We are a leading global manufacturer of some of the largest and most technologically advanced parts and assemblies for a diverse range of aircraft. Our capabilities include aerostructures, precision assembly techniques, automated assembly processes and large-bed machining and fabrication of large composite fiber reinforced parts, highly proprietary actuation products, geared products, structural components, and thermal products and controls. The Company employs over 1,000 engineers supporting design programs and manufacturing. Our manufacturing facilities have achieved ISO 9001 certification, a certification of internationally recognized quality standards for manufacturing. Triumph continues to invest in new technology. With Triumph companies located throughout the world we have resources positioned close to our customers for rapid response.

Significant customer relationships and industry presence. We believe that our strong customer relationships and strong 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. The Company's customer base includes nearly all of the world's major OEMs (Boeing, Airbus, Bell Helicopter, Cessna, Gulfstream, Sikorsky, Lockheed Martin, Raytheon, Honeywell and General Electric), commercial airlines, the U.S. military and air cargo carriers, including Federal Express and United Parcel Service. The Company is an important supplier to many long-lived commercial and military platforms, including, Airbus A320, A330, A380, Boeing 737, 747- 8, 767, 777 and 787, CH-47 Chinook, CH-53, KC46A tanker and V-22 Osprey, Bombardier Global 7000/8000, Lockheed Martin C-130, Northrop Grumman Global Hawk, Sikorsky UH-60 Black Hawk, F-16, F-35, Cessna CJ4, Cessna Mustang 550, Gulfstream G650 and G280. In addition, the Company is well positioned to capitalize on other new program launches.

Robust backlog. As of September 30, 2017 and March 31, 2017, our backlog was approximately $4.28 billion and $3.98 billion, respectively. 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.

Conservative financial strategy. Our total net debt to capitalization, on a pro forma basis after giving effect to this offering and the application of net proceeds therefrom, was 61.4% as of September 30, 2017. In addition, as of September 30, 2017, we had $33.7 million of cash and cash equivalents and $652.3 million of availability under our revolving credit facility. For the twelve-month

Table of Contents

period ended September 30, 2017, our total net debt to Adjusted EBITDA (as reported) was 4.3x and our total net debt to Adjusted EBITDA (as further adjusted) would be 3.7x.

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 through various industry cycles. We believe our management has the vision, focus and experience to position us for success in the future.

Business Strategy

We are currently engaged in a transformation of the organization. In order to aggregate capabilities, build leverageable scale, and reduce cost, we consolidated our businesses into four business units described above.

Our strategic approach to transforming and growing these four businesses includes two phases. The first phase, spanning fiscal years 2018 and 2019, includes resolving contractual uncertainties within our Aerospace Structures business, turning around our Precision Components machining businesses, and executing key targeted divestitures. Execution of these three key imperatives are expected to reduce liabilities and uncertainties, improve margins and cash flow, and provide capital for selective investment.

The second phase, spanning fiscal years 2019 and 2020, includes investments in both organic growth opportunities and targeted acquisitions within our profitable and growing Integrated Systems, and Product Support businesses.

Our Integrated Systems business is built on a strong foundation of engineering knowledge and intellectual property. Leveraging this foundation will enable the accelerated expansion of market share and technology in our markets through increased research and development and strategic mergers and acquisitions. For instance, within the actuation market, mergers and acquisitions will be primarily targeted at complementary engineered product solutions and/or protection of key capabilities which may include increasing the vertical integration of vital engineered components to control pricing pressure within the various actuation markets.

Our Product Support business thrives on best-in-class service, qualifications, and strong customer relationships. Key service attributes such as responsiveness, available product, industry leading cycle times, and remaining close to our customers enables the expansion of business, while investments in rotable pools of equipment, such as nacelles, flight control surfaces and accessories result in near term capture of fleet sustainment revenues with both existing and new customers. Several attractive options also exist for consolidating accessory capabilities within our existing footprint and expanding operations internationally in existing or new lower cost locations.

Table of Contents

We plan to continue to pursue our transformation to stabilize our loss-making and negative cash programs. In fiscal year 2016 we launched a cost reduction initiative, focusing on facilities consolidation, management consolidation and reductions in workforce, supply chain management enhancements and shop floor productivity improvements. We plan to continue to focus on cost savings and improving our balance sheet strength and liquidity. See "Risk factors—Risks relating to our business and our industry—We may not be successful in achieving expected operating efficiencies and sustaining or improving operating expense reductions, and may experience business disruptions associated with restructuring, facility consolidations, realignment, cost reduction and other strategic initiatives."

Additionally, acquisitions will be considered where they can provide high value, near term returns, such as acquiring MRO businesses and inserting them into Product Support, where property and equipment, qualifications, and skills may be redundant or highly complementary, allowing significant margin enhancements through cost reductions, footprint consolidations and increased asset utilization.

Within the overall approach above, we are also engaged in opportunities for growth through the replacement of underperforming competitors, extending our existing products and capabilities within our core markets, increasing our penetration of existing customers, and establishing new customers within and adjacent to our core markets and capabilities.

More generalized strategies remain applicable as the Triumph transformation continues:

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, airlines and air cargo carriers.

Improve operations. We plan to continue to improve our operations to support our customers' demand for capacity while at the same time right sizing our businesses through product transfers, facility consolidations, divestitures, mergers and acquisitions, to meet the demands for cost. 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.

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 more than 40 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 in the aerospace industry. Through selective 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.

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.

		Subject to the terms of this exchange offer, we will exchange new notes for all of the old notes that are validly tendered and not withdrawn prior to the expiration of this exchange offer. The new notes will be issued in exchange for corresponding old notes in this exchange offer, if consummated, as soon as practicable after the expiration of this exchange offer.

Table of Contents


Procedures for Tendering		If you wish to accept this exchange offer and your old notes are held by a custodial entity such as a bank, broker, dealer, trust company or other nominee, you must instruct this custodial entity to tender your old notes on your behalf pursuant to the procedures of the custodial entity. If your old notes are registered in your name, you must complete, sign and date the accompanying letter of transmittal, or a facsimile of the letter of transmittal, according to the instructions contained in this offer to exchange and the letter of transmittal. You must also mail or otherwise deliver the letter of transmittal, or a facsimile of the letter of transmittal, together with the old notes and any other required documents, to the exchange agent at the address set forth on the cover page of the letter of transmittal.
		Custodial entities that are participants in The Depository Trust Company ("DTC") may tender old notes through DTC's Automated Tender Offer Program ("ATOP") which enables a custodial entity, and the beneficial owner on whose behalf the custodial entity is acting, to electronically agree to be bound by the letter of transmittal.A letter of transmittal need not accompany tenders effected through ATOP.
		By signing, and agreeing to be bound by, the letter of transmittal, you will represent to us that, among other things:
		you are acquiring the new notes in the ordinary course of your business;
		you have no arrangement or understanding with any person to participate in a distribution (within the meaning of the Securities Act) of the new notes;
		you are not an affiliate of the issuer (within the meaning of Rule 405 under the Securities Act); and
		if you are a broker-dealer registered under the Exchange Act, you are participating in the exchange offer for your own account and are exchanging old notes acquired as a result of market -making activities or other trading activities and you will deliver an offer to exchange in connection with any resale of the new notes.
		See "The Exchange Offer-Eligibility; Transferability."
Transferability		Under existing interpretations of the Securities Act by the staff of the SEC contained in several no-action letters to third parties, and subject to the immediately following sentence, we believe that the new notes will generally be freely transferable by holders after the exchange offer without further compliance with the registration and offer to exchange delivery requirements of the Securities Act (subject to representations required to be made by each holder of old notes, as set forth above). However, any holder of old notes who:

Table of Contents


		• is one of our "affiliates" (as defined in Rule 405 under the Securities Act),
		• does not acquire the new notes in the ordinary course of business,
		• distributes, intends to distribute, or has an arrangement or understanding with any person to distribute the new notes as part of the exchange offer, or
		• is a broker-dealer who purchased old notes directly from us,
		will not be able to rely on the interpretations of the staff of the SEC, will not be permitted to tender old notes in the exchange offer and, in the absence of any exemption, must comply with the registration and offer to exchange delivery requirements of the Securities Act in connection with any resale of the new notes.
		Our belief that transfers of new notes would be permitted without registration or offer to exchange delivery under the conditions described above is based on SEC interpretations given to other, unrelated issuers in similar exchange offers. We cannot assure you that the SEC would make a similar interpretation with respect to our exchange offer. We will not be responsible for or indemnify you against any liability you may incur under the Securities Act.
		Each broker-dealer that receives new notes for its own account under the exchange offer in exchange for old notes that were acquired by the broker-dealer as a result of market -making or other trading activity must acknowledge that it will deliver an offer to exchange in connection with any resale of the new notes. See "Plan of Distribution."
Consequences of Failure to Exchange		Any old notes that are not tendered in the exchange offer, or that are not accepted in the exchange, will remain subject to the restrictions on transfer. Since the old notes have not been registered under the U.S. federal securities laws, you will not be able to offer or sell the old notes except under an exemption from the requirements of the Securities Act or unless the old notes are registered under the Securities Act. Upon the completion of the exchange offer, we will have no further obligations, except under limited circumstances, to provide for registration of the old notes under the U.S. federal securities laws. See "The Exchange Offer-Consequences of Failure to Tender."
Use of Proceeds		We will not receive any proceeds from the exchange of notes pursuant to the exchange offer. We will pay all expenses incident to the exchange offer.

RISK FACTORS

An investment in the 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 about investing in the notes, you should carefully consider the following discussion of risks and the other information in this offer to exchange, and carefully read the risks described in the documents incorporated by reference in this offer to exchange, including those set forth under the caption "Risk Factors" in our Annual Report on Form 10-K for the fiscal year ended March 31, 2017.

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 derives from commercial aviation. 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 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 hostility in oil-producing areas. Airlines are sometimes 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 natural disasters, war, 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 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

We may not be successful in achieving expected operating efficiencies and sustaining or improving operating expense reductions, and may experience business disruptions associated with restructuring, facility consolidations, realignment, cost reduction and other strategic initiatives.

Over the past several years we have implemented a number of restructuring, realignment and cost reduction initiatives, including facility consolidations, organizational realignments and reductions in our workforce. While we have realized some efficiencies from these actions, we may not realize the benefits of these initiatives to the extent we anticipated. Further, such benefits may be realized later than expected, and the ongoing difficulties in implementing these measures may be greater than anticipated, which could cause us to incur additional costs or result in business disruptions. For example, our current restructuring plan involves the consolidation of certain of our facilities, which has resulted in an inability to bid for certain programs or new sales. In addition, if these measures are not successful or sustainable, we may be compelled to undertake additional realignment and cost reduction efforts, which could result in significant additional charges. Moreover, if our restructuring and realignment efforts prove ineffective, our ability to achieve our other strategic and business plan goals may be adversely affected. Lastly, these initiatives have required us to take significant cash and non-cash charges. Over the course of our current initiatives (which were initiated in fiscal 2016), we estimate that we will record aggregate pre-tax charges of $195.0 million to $210.0 million related to these initiatives, which represent employee termination benefits, contract termination costs, accelerated depreciation and facility closure and other exit costs, and will result in future cash outlays. For the year ended March 31, 2017, we recognized $42.2 million in cash restructuring charges and $10.8 million in non-cash restructuring charges, and for the six months ended September 30, 2017, we recognized $27.6 million in cash restructuring charges and $2.2 million in non-cash restructuring charges. We anticipate that our future cash restructuring charges will comprise a similar proportion.

We derive a significant portion of our revenue from the U.S. government, primarily from defense related programs with the U.S. Department of Defense.

Levels of U.S. defense spending are very difficult to predict and may be impacted by numerous factors such as the political environment, U.S. foreign policy, macroeconomic conditions and the ability of the U.S. government to enact relevant legislation such as authorization and appropriations bills.

In addition, significant budgetary delays and constraints have already resulted in reduced spending levels, and additional reductions may be forthcoming. The Budget Control Act of 2011 (The Act) established limits on U.S. government discretionary spending, including a reduction of defense spending between the 2012 and 2021 U.S. government fiscal years. Accordingly, long-term uncertainty remains with respect to overall levels of defense spending and it is likely that U.S. government discretionary spending levels will continue to be subject to pressure.

In addition, there continues to be significant uncertainty with respect to program-level appropriations for the U.S. Department of Defense ("U.S. DoD") and other government agencies within the overall budgetary framework described above. While the House and Senate Appropriations committees included funding for major military programs in fiscal year 2018, such as CH-47 Chinook, AH-64 Apache, KC-46A Tanker, UH-60 Black Hawk, Northrop Grumman Global Hawk and V-22 Osprey programs, uncertainty remains about how defense budgets in fiscal year 2018 and beyond will affect these programs. Future budget cuts, including cuts mandated by sequestration, or future procurement decisions associated with the authorizations and appropriations process could result in reductions, cancellations, and/or delays of existing contracts or programs. Any of these impacts could have a material effect on the results of the Company's operations, financial position and/or cash flows.

In addition, as a result of the significant ongoing uncertainty with respect to both U.S. defense spending levels and the nature of the threat environment, we expect the U.S. DoD to continue to emphasize cost-cutting and other efficiency initiatives in its procurement processes. If we can no longer

Table of Contents

adjust successfully to these changing acquisition priorities and/or fail to meet affordability targets set by the U.S. DoD customer, our revenues and market share would be further impacted.

The profitability of certain development programs depends significantly on the assumptions surrounding satisfactory settlement of claims and assertions.

For certain of our new development programs, we regularly commence work or incorporate customer-requested changes prior to negotiating pricing terms for engineering work or the product which has been modified. We typically have the legal right to negotiate pricing for customer-directed changes. In those cases, we assert to our customers our contractual rights to obtain the additional revenue or cost reimbursement we expect to receive upon finalizing pricing terms. An expected recovery value of these assertions is incorporated into our contract profitability estimates when applying contract accounting. However, we may not be able to recover these expected values due to inadequate lead time or other reasons generally discussed below under "—We incur risk associated with new and ongoing programs." Our inability to recover these expected values, among other factors, could result in the recognition of a forward loss on these programs or a lower than expected profit margin and could have a material adverse effect on our 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 may 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. In addition, because of the possibility of our Vought Aircraft Division (Triumph Aerostructures, LLC) and certain affiliated entities commencing voluntary insolvency proceedings pursuant to the eighth amendment to our credit facilities we entered into on May 1, 2017 (prior to our settlement with Bombardier upon which such insolvency threat lapsed). As of September 30, 2017, we financed $0 worth of eligible accounts receivable, compared to $78.0 million worth of eligible accounts receivable as of March 31, 2017. If this difficulty continues in future period, it would negatively affect our operating cash flows and limit our working capital.

We incur risk associated with new and ongoing programs.

Our programs, particularly new programs with new technologies, typically carry risks associated with design responsibility, development of new production tools, hiring and training of qualified personnel, increased capital and funding commitments, ability to meet customer specifications, delivery schedules and unique contractual requirements, supplier performance, ability of the customer to meet its contractual obligations to us, and our ability to accurately estimate costs associated with such programs. In addition, any new aircraft program may not generate sufficient demand or may experience technological problems or significant delays in the regulatory certification or manufacturing and delivery schedule. Our customers may terminate their contracts with us if we do not meet specification

Table of Contents

requirements, delivery schedules and other contractual requirements. If we were unable to perform our obligations under new programs to the customer's satisfaction or manufacture products at our estimated costs, if we were to experience unexpected fluctuations in raw material prices or supplier problems leading to cost overruns, if we were unable to successfully perform under revised design and manufacturing plans or successfully resolve claims and assertions, or if a new program in which we had made a significant investment was terminated or experienced weak demand, delays or technological problems, our business, financial condition and results of operations could be materially adversely affected. This risk includes the potential for default, quality problems, or inability to meet weight requirements and could result in low margin or forward loss contracts, and the risk of having to write-off inventory if it were deemed to be unrecoverable over the life of the program. In addition, beginning new work on existing programs also carries risks associated with the transfer of technology, knowledge and tooling.

The risk associated with our programs also includes contractual risks with respect to pricing. For example, we anticipate continued declines in net sales in fiscal year 2018 due to production rate reductions and price step-downs on certain Boeing programs in addition to certain sunsetting programs.

In order to perform on our new or ongoing programs we may be required to construct or acquire new facilities requiring additional up-front investment costs. In the case of significant program delays and/or program cancellations, we could be required to bear certain unrecoverable construction and maintenance costs and incur potential impairment charges for the new facilities. Also, we may need to expend additional resources to determine an alternate revenue generating use for the facilities. Likewise, significant delays in the construction or acquisition of a plant site could impact production schedules.

Our business could be negatively affected by cyber or other security threats or other disruptions.

Our businesses depend heavily on information technology and computerized systems to communicate and operate effectively. The Company's systems and technologies, or those of third parties on which we rely, could fail or become unreliable due to equipment failures, software viruses, cyber threats, terrorist acts, natural disasters, power failures or other causes. These threats arise in some cases as a result of our role as a defense contractor.

Cybersecurity threats are evolving and include, but are not limited to, malicious software, attempts to gain unauthorized access to our sensitive information, including that of our customers, suppliers, subcontractors, and joint venture partners, and other electronic security breaches that could lead to disruptions in mission critical systems, unauthorized release of confidential or otherwise protected information, and corruption of data.

Although we utilize various procedures and controls to monitor and mitigate these threats, there can be no assurance that these procedures and controls will be sufficient to prevent security threats from materializing. If any of these events were to materialize, the costs related to cyber or other security threats or disruptions may not be fully insured or indemnified and could have a material adverse effect on our reputation, operating results, and financial condition.

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

Table of Contents

changing economic conditions, inventory adjustments, or work stoppages or labor disruptions at our customers' locations. 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.

The possibility of voluntary insolvency proceedings has negatively affected our business and could continue to have a material adverse effect on us.

Pursuant to our eighth amendment to our credit facilities, our Vought Aircraft Division (Triumph Aerostructures, LLC) and certain affiliated entities obtained the option to commence voluntary insolvency proceedings subject to certain conditions, which option expired on July 31, 2017. The possibility of voluntary insolvency proceedings (prior to our settlement with Bombardier upon which such insolvency threat lapsed) has caused some of our suppliers to shorten payment periods, which has negatively affected our operating cash flows. Such trends lessen our financial flexibility and may have a material adverse effect on our liquidity and capital resources.

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

We previously had a consistent strategy to grow, in part, through the acquisition of additional businesses in the aerospace industry and may in the future evaluate 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 loss of key employees of acquired companies, the potential amortization of acquired intangible assets and the potential impairment of goodwill. For example, for the fiscal year ended March 31, 2017, we concluded that the goodwill related to our Aerospace Structures segment was impaired due to the decline in fair value as the result of declining revenues from production rate reductions on sunsetting programs and the slower than previously projected ramp in our development programs and the timing of associated earnings and cash flows. In addition, while we concluded that the goodwill related to our Precision Components segment was not impaired as of the testing date for the fiscal year ended March 31, 2017, there was a decline in fair value as the result of declining revenues from production rate reductions on sunsetting programs and the start-up costs related to new programs and the timing of associated earnings and cash flows, and we may have to record goodwill impairment charges for this segment in future periods. We may not be able to successfully integrate acquired businesses.

We may consider potential dispositions of assets or businesses as part of our overall business restructuring strategy and we may not be successful in realizing anticipated benefits.

We intend to continue to strategically position certain of our business units in order to improve our ability to compete. Our management may consider from time to time the potential disposition of assets or businesses that no longer meet our growth, return, or strategic objectives. In selling assets or businesses, we may not get prices or terms as favorable as we anticipated. We could also encounter difficulty in finding buyers on acceptable terms in a timely manner, which could delay our accomplishment of strategic objectives. Expected cost savings or other strategic benefits relating to the disposed assets or businesses may not materialize, and reductions in overhead and other related actions could temporarily disrupt our other business operations. Any of these outcomes could negatively affect our business and profitability.

Table of Contents

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

Boeing, or Boeing Commercial, Military and Space, represented approximately 35% and 33%, respectively, of our net sales the fiscal year ended March 31, 2017 and the six months ended September 30, 2017, covering virtually every Boeing plant and product. Gulfstream represented approximately 12% and 13%, respectively, of our net sales for the fiscal year ended March 31, 2017 and for the six months ended September 30, 2017, covering several Gulfstream plants and products. As a result, a significant reduction in purchases by Boeing and/or Gulfstream could have a material adverse impact on our financial condition, results of operations, and cash flows. In addition, some of our individual companies rely significantly on particular customers, the loss of which could have an adverse effect on those businesses.

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 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 Canada, China, France, Germany, Ireland, Mexico, Thailand and the United Kingdom, and customers throughout the 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;

Table of Contents

•: 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 internal growth and 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 Credit Agreement and the Securitization Facility (each as defined herein) and by particular restrictions contained in the Credit Agreement 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, Bombardier, Cessna, General Electric, 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, Fokker Technologies, Fuji Heavy Industries, GKN Westland Aerospace (U.K.), Kawasaki Heavy Industries, Mitsubishi Heavy Industries, Spirit AeroSystems and UTC Aerospace Systems. Some of our competitors, particularly our foreign competitors, may be able to offer more competitive pricing in areas that have less barriers to entry or where we have higher legacy costs, such as less specialized manufacturing. We may lack the capacity to compete against certain manufacturers with respect to, among other factors, production volume and timing. 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. The competitive pressures we face may result in reduced revenues and market share.

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, such as additive technology, 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.

Table of Contents

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.

Our business could be materially adversely affected by product warranty obligations.

Our operations expose us to potential liability for warranty claims made by customers or third parties with respect to aircraft components that have been designed, manufactured, or serviced by us or our suppliers. Material product warranty obligations could have a material adverse effect on our business, financial condition and results of operations.

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, should insurance market conditions change, general aviation product liability, 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.

We depend on key personnel and turnover of key senior management, as well as the lack of available skilled personnel, may have an adverse effect on our operations.

Our business and results of operations depend upon the continued contributions of key senior management team members, many of whom have recently joined us. In addition, 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. Further, we may experience increased costs as a result of investments in attracting, retaining and training management talent.

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

A significant portion of our net sales are 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 vary substantially from our original estimates, and we bear the risk that increased or unexpected costs may reduce our

Table of Contents

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 our profitability or cause significant losses. For example, over the last few years we recorded forward losses on our Boeing 747-8 and Bombardier Global 7000/8000 contracts.

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 ("GAAP"). 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.

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. In addition, we could be affected by future laws and regulations, including those imposed in response to climate change concerns and other actions commonly referred to as "green initiatives." Compliance with current and future environmental laws and regulations currently requires and is expected to continue to require significant operating and capital costs.

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 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 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

Table of Contents

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. Also, as we proceed with our plans to exit certain facilities as part of restructuring and related initiatives, the need for remediation for potential environmental contamination could be identified. However, if we are required to pay the expenses related to environmental liabilities because 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 could become involved in intellectual property litigation, which could have a material and adverse impact on our profitability.

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. 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 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.

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.

Table of Contents

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;
•: reduction to credit terms; 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.

In the past, the possibility of our commencement of voluntary insolvency proceedings (prior to our settlement with Bombardier upon which such insolvency threat lapsed) has caused some of our suppliers to shorten payment periods, which has negatively affected our operating cash flows. Such trends lessen our financial flexibility and may have a material adverse effect on our liquidity and capital resources.

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 or our customers' 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 or for our customers and suppliers, however, a major catastrophe, such as an earthquake, hurricane, fire, 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. For leased facilities, timely renewal of leases and risk mitigation from the sale of our leased facilities is required to avoid any business interruption.

Table of Contents

Our reputation, our ability to do business and our financial position, results of operations and/or cash flows may be impacted by the improper conduct of employees, agents, subcontractors, suppliers, business partners or joint ventures in which we participate.

We have implemented policies, procedures, training and other compliance controls, and have negotiated terms designed to prevent misconduct by employees, agents or others working on our behalf or with us that would violate the applicable laws of the jurisdictions in which we operate, including laws governing improper payments to government officials, the protection of export controlled or classified information, cost accounting and billing, competition and data privacy. However, we cannot ensure that we will prevent all such misconduct committed by our employees, agents, subcontractors, suppliers, business partners or others working on our behalf or with us, and this risk of improper conduct may increase as we expand globally. In the ordinary course of our business we form and are members of joint ventures. We may be unable to prevent misconduct or other violations of applicable laws by these joint ventures (including their officers, directors and employees) or our partners. Improper actions by those with whom or through whom we do business (including our employees, agents, subcontractors, suppliers, business partners and joint ventures) could subject us to administrative, civil or criminal investigations and monetary and non-monetary penalties, including suspension and debarment, which could negatively impact our reputation and ability to conduct business and could have a material adverse effect on our financial position, results of operations and/or cash flows.

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

The aerospace industry continues to experience consolidation among suppliers and customers, primarily the airlines. 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.

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, 2017, we employed 14,309 people, of which 12.4% belonged to unions. Our unionized workforces and those of our customers and suppliers may experience work stoppages. For example, during the quarter ended June 30, 2016, we settled the strike and agreed to a new collective bargaining agreement with our union employees with IAM District 751 at our Spokane, Washington facility which had expired during the quarter. While we were in negotiations with the workforce, we were able to implement plans that allowed us to continue production in Spokane with the support from our other locations. Our union employees with Local 848 at our Red Oak, Texas and Local 952 at our Tulsa, Oklahoma, facilities of the United Auto Workers ("UAW") are currently working without a contract. If we are unable to negotiate a contract with those workforces, 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. Contingency plans have been developed that would allow production to continue in the event of a strike.

Many aircraft manufacturers, airlines and aerospace suppliers have unionized workforces. Strikes, work stoppages or slowdowns experienced by aircraft manufacturers, airlines or aerospace suppliers could reduce our customers' demand for our products or prevent us from completing production. In

Table of Contents

turn, this may have a material adverse effect on our financial condition, results of operations and cash flows.

Financial market conditions may adversely affect the benefit plan assets for our defined benefit plans, increase funding requirements and materially impact our statements of financial position and cash flows.

Our benefit plan assets are invested in a diversified portfolio of investments in both the equity and debt categories, as well as limited investments in 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 on 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 a decrease in interest rates resulting from movements in the financial markets will increase the under-funded status of the plans recorded on our Consolidated Balance Sheet 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.

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.

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 we may be required to seek higher level clearances in the future. We cannot assure you that we will be

Table of Contents

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.

Regulations related to conflict minerals have and will continue to force us to incur additional expenses, may make our supply chain more complex, and could adversely impact our business.

The Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 contains provisions to improve transparency and accountability concerning the supply of certain minerals and metals, known as conflict minerals, originating from the Democratic Republic of Congo (the "DRC") and adjoining countries. As a result, in August 2012, the SEC adopted annual investigation, disclosure and reporting requirements for those companies that manufacture or contract to manufacture products that contain conflict minerals that originated from the DRC and adjoining countries. We have and will continue to incur compliance costs, including costs related to determining the sources of conflict minerals used in our products and other potential changes to processes or sources of supply as a consequence of such verification activities. The implementation of these rules could adversely affect the sourcing, supply and pricing of materials used in certain of our products. As there may be only a limited number of suppliers offering "conflict free" minerals, we cannot be sure that we will be able to obtain necessary conflict-free minerals from such suppliers in sufficient quantities or at competitive prices. Also, we may face reputational challenges if we determine that certain of our products contain minerals not determined to be conflict free.

Our business is subject to regulation in the United States and internationally.

The manufacturing of our products is subject to numerous federal, state and foreign governmental regulations. The number of laws and regulations that are being enacted or proposed by various governmental bodies and authorities are increasing. Compliance with these regulations is difficult and expensive. If we fail to adhere, or are alleged to have failed to adhere, to any applicable federal, state or foreign laws or regulations, or if such laws or regulations negatively affect sales of our products, our business, prospects, results of operations, financial condition or cash flows may be adversely affected. In addition, our future results could be adversely affected by changes in applicable federal, state and foreign laws and regulations, or the interpretation or enforcement thereof, including those relating to manufacturing processes, product liability, government contracts, trade rules and customs regulations, intellectual property, consumer laws, privacy laws, as well as accounting standards and taxation requirements (including tax rate changes, new tax laws, revised tax law interpretations, or other potential impacts outlined in proposals on U.S. tax reform).

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

Table of Contents

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.

Broker-dealers may become subject to the registration and offer to exchange 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 offer to exchange 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.

Table of Contents

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

As of September 30, 2017, our total indebtedness was approximately $1,450.7 million. We also had an additional $652.3 million available for borrowing under our Revolving Credit Facility as of September 30, 2017. 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.

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, and the indenture governing the new notes offered hereby will 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 September 30, 2017, we had $208.4 million of indebtedness subject to floating interest rates. A 1% increase in floating interest rates would have increased such annual interest expense by approximately $2.1 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. 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 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;

Table of Contents

•: 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.

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 offer to exchange.

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

Table of Contents

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 September 30, 2017, we had $275.7 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 new notes.

For the fiscal year ended March 31, 2017, the non-guarantor subsidiaries of the Company generated 10.8% and 9.1% of the Company's net sales and Adjusted EBITDA, respectively. In addition, as of September 30, 2017, on the same basis, the non-guarantor subsidiaries of the Company held 17.6% of the Company's assets and 15.8% 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 New 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 U.S. federal bankruptcy law and comparable provisions of state fraudulent

Table of Contents

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.

Table of Contents

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.

A lowering or withdrawal of the ratings assigned to our debt securities by rating agencies may increase our future borrowing costs and reduce our access to capital.

Our debt currently has a non-investment grade rating, and any rating assigned could be lowered or withdrawn entirely by a rating agency if, in that rating agency's judgment, future circumstances relating to the basis of the rating, such as adverse changes, so warrant. Consequently, real or anticipated changes in our credit ratings will generally affect the market value of the notes. Credit ratings are not recommendations to purchase, hold or sell the notes. Additionally, credit ratings may not reflect the potential effect of risks relating to the structure or marketing of the notes. Any downgrade may result in higher borrowing costs.

Any future lowering of our ratings likely would make it more difficult or more expensive for us to obtain additional debt financing. If any credit rating initially assigned to the notes is subsequently lowered or withdrawn for any reason, you may not be able to resell your notes without a substantial discount.

THE EXCHANGE OFFER

In connection with the issuance of the old notes on August 17, 2017, 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 offer to exchange 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.

Table of Contents

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

•: cause to be filed within 180 days after August 17, 2017 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 August 17, 2017, 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 an offer to exchange 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.

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 offer to exchange 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

Table of Contents

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 offer to exchange 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 that 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 an offer to exchange in connection with any resale of the new notes. The letter of transmittal states that by acknowledging that it will deliver, and by delivering, an offer to exchange, a broker-dealer will not be deemed to admit that it is an underwriter within the meaning of the Securities Act. This offer to exchange, 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 offer to exchange 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 offer to exchange 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 January 18, 2018 (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.

Table of Contents

If we amend the exchange offer in a manner that we consider material, we will disclose such amendment by means of an offer to exchange 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.

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, as amended (the "Trust Indenture Act"). 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

Table of Contents

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 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 offer to exchange 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 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

Table of Contents

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 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.

Table of Contents

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 offer to exchange. 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.

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:


By Mail:		U.S. Bank National Association 60 Livingston Avenue Mail Station-EP -MN-WS2N St. Paul, Minnesota 55107-2292 Attention: Specialized Finance
By Registered or Certified Mail, Hand or Overnight Delivery:		U.S. Bank National Association 111 Fillmore Avenue St. Paul, Minnesota 55107-1402 Attention: Specialized Finance
Facsimile Transmissions:		(651) 466-7367
Telephone:		(800) 934-6802

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.

Table of Contents

Fees and Expenses

We will bear the expenses of soliciting exchanges of notes. 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.

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.

Table of Contents

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 August 17, 2017 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 August 17, 2017;
•: use our reasonable best efforts to consummate the exchange offer not later than 30 days after the 270th day after August 17, 2017; 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.

In the event that:

•: the registration statement is not filed with the SEC on or prior to the 180th day after August 17, 2017;
•: the registration statement has not been declared effective by the SEC on or prior to the 270th day after August 17, 2017; or
•: the exchange offer is not completed or the shelf registration statement, if required, has not become effective on or prior to the 300th day after August 17, 2017 (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."

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.

DESCRIPTION OF CERTAIN INDEBTEDNESS

We summarize below the principal terms of certain of our outstanding indebtedness. This summary is not a complete description of all of the terms of our outstanding indebtedness and is qualified in its entirety by reference to the relevant agreements, which are exhibits to the documents incorporated by reference herein.

Credit facilities

On November 19, 2013, the Company entered into a Third Amended and Restated Credit Agreement, among the Company, substantially all of its domestic subsidiaries as co-borrowers and guarantors, PNC Bank, National Association, as administrative agent, and the other lenders party thereto (as heretofore amended, modified, supplemented or restated, the "Credit Agreement"), which provided for commitments of up to $1.0 billion for a revolving credit facility and a $375.0 million term loan facility. $51.1 million of commitments under the revolving credit facility mature on November 19, 2018 and $798.9 of commitments under the revolving credit facility mature on May 3, 2021 (or December 31, 2020 if the 2021 Notes (as defined below) are still outstanding on that date). The maturity date of the term loan facility is March 31, 2019. We expect to use the proceeds from this offering to repay amounts outstanding under our credit facilities.

On July 31, 2017, the Company and its subsidiary co-borrowers and guarantors entered into a Ninth Amendment to the Third Amended and Restated Credit Agreement (the "Ninth Amendment") to, among other things, (i) permit the Company to incur the notes offered hereby in an aggregate principal amount of up to $500.0 million, subject to the Company's obligations to apply the net proceeds from this offering to repay the outstanding principal amount of the Loans and/or permanently reduce commitments under the Credit Agreement, (ii) limit the mandatory prepayment provisions to (a) eliminate the requirement that net proceeds received from the incurrence of Permitted Indebtedness (as defined in the Credit Agreement) be applied to reduce the revolving credit commitments once the revolving credit commitments have been reduced to $800.0 million, (b) eliminate the requirement that the Company repay the loans and permanently reduce the revolving credit commitments using any net proceeds from the Company's issuance of capital stock and (c) eliminate the requirement that the net proceeds from certain asset sales be applied to repay the loans and permanently reduce the revolving credit commitments, to the extent that such net proceeds are reinvested in the business of the Company or its subsidiaries within 360 days after the receipt thereof, (iii) add, for purposes of determining whether the loan parties can incur permitted indebtedness (other than the notes offered hereby), a maximum total leverage test of less than 4.50 to 1.00 as if such permitted indebtedness had been incurred, (iv) lower the minimum interest coverage ratio to 2.75 to 1.00, (v) modify the senior secured leverage ratio to set the maximum level at 3.50 to 1.00 and to remove any additional step downs thereof, (vi) remove all of the covenant restriction period restrictions, which limited the Company's ability to access the accordion, make stock repurchases and certain dividends, enter into acquisitions and prepay certain specified indebtedness, (vii) add, with respect to permitting acquisitions, a maximum total leverage test of less than 4.50 to 1.00 and reduce the minimum availability requirement from $300.0 million to $200.0 million, (viii) set current interest rate and letter of credit pricing tiers to LIBOR +350 basis points (base rate + 250 basis points) the commitment fee to 50 basis points as the pricing for the remainder of the term, (ix) eliminate certain categories of specified asset sales and the corresponding mandatory prepayment provisions related thereto, (x) modify the existing category of permitted asset sales to permit assets sales, in any given fiscal year, to the extent the aggregate net proceeds received therefrom do not exceed 10% of Company's consolidated total assets (as determined as of the first day of such fiscal year) and only require the net proceeds of such asset sales to be applied to prepay the Loans (as defined in the Credit Agreement) and reduce the revolving credit commitments to the extent such net proceeds are not reinvested in the business of the Company or its subsidiaries within 360 days after the receipt thereof

Table of Contents

and (xi) eliminate all references to the permitted potential voluntary insolvency of the Company's Vought Aircraft Division (Triumph Aerostructures Holdings, LLC) and/or certain affiliated entities (collectively, the "Vought entities"). The effectiveness of the Ninth Amendment is contingent upon the completion of this offering and the application of net proceeds from this offering to prepay the outstanding principal amount of the Loans and/or permanently reduce commitments under the Credit Agreement.

In May 2017, the Company entered into an Eighth Amendment to the Third Amended and Restated Credit Agreement (the "Eighth Amendment") and its subsidiary co-borrowers and guarantors, among the Company and its lenders to, among other things, (i) eliminate the total leverage ratio financial covenant, (ii) increase the maximum permitted senior secured leverage ratio financial covenant applicable to each fiscal quarter, commencing with the fiscal quarter ended March 31, 2017, and to revise the step-downs applicable to such financial covenant, (iii) reduce the aggregate principal amount of commitments under the revolving line of credit to $850.0 million from $1.0 billion, (iv) modify the maturity date of the term loans so that all of the term loans will mature on March 31, 2019, and (v) establish a new higher pricing tier for the interest rate, commitment fee and letter of credit fee pricing provisions and provide that the highest pricing tier will apply until the maximum senior secured leverage ratio financial covenant is 2.50 to 1.00 and the Company delivers a compliance certificate demonstrating compliance with such financial covenant. In connection with the Eighth Amendment, the Company incurred $6.8 million of financing costs. These costs, along with the $10.5 million of unamortized financing costs prior to the amendment, are being amortized over the remaining term of the Credit Agreement. In accordance with the reduction of the Credit Agreement, the Company impaired a proportional amount of unamortized financing fees prior to the amendment.

The Eighth Amendment also provided Vought entities with the option, if necessary, to commence voluntary insolvency proceedings within 90 days of the Eighth Amendment Effective Date, subject to certain conditions set forth in the Credit Agreement. Upon the commencement of such proceedings, the Vought entities would no longer be Subsidiary Co-Borrowers under the Credit Agreement, and transactions between any of the Vought entities, on the one hand, and the Company and any of the Subsidiary Co-Borrowers, on the other hand, would have been restricted. The Company entered into the Eighth Amendment, among other reasons, in order to provide the Vought entities with greater financial flexibility to address their significant cash utilization relative to certain contracts. The Company expected that any action it may have taken regarding the Vought entities would have improved the Company's credit profile and equity value. The Company's option to commence voluntary insolvency for the Vought entities expired on July 31, 2017.

In October 2016, the Company and its subsidiary co-borrowers and guarantors entered into a Seventh Amendment to the Third Amended and Restated Credit Agreement, among the Company, the Subsidiary Co-Borrowers, the lenders party thereto and the Administrative Agent (the "Seventh Amendment"). Specifically, the Credit Agreement was amended to, among other things, (i) modify certain financial covenants to allow for the add-back of certain cash and non-cash charges, (ii) increase the maximum permitted total leverage ratio and senior secured leverage ratio financial covenants commencing with the fiscal quarter ended September 30, 2016 through the fiscal quarter ending June 30, 2017, (iii) permit the sale of certain specified assets so long as the Company applies 65.0% of the net proceeds received from such sales to the outstanding term loan, pro rata across all maturities, (iv) establish a new higher pricing tier for the interest rate, commitment fee and letter of credit fee pricing provisions, (v) increase the interest rate and letter of credit fee pricing provisions for several of the lower tiers of the pricing grid, (vi) establish the interest rate, commitment fee and letter of credit fee pricing at the highest pricing tier until the Company delivers its compliance certificate for its fiscal quarter ending September 30, 2017, and (vii) extend the period during which the increased minimum revolver availability threshold test and the decreased maximum senior secured leverage ratio threshold test are in effect in connection with the Company making certain permitted investments, certain

Table of Contents

additional permitted dividends, permitted acquisitions and permitted payments of certain types of indebtedness to the date the Company delivers its compliance certificate for the fiscal quarter ending September 30, 2017.

In May 2016, the Company and its subsidiary co-borrowers and guarantors entered into a Sixth Amendment to the Third Amended and Restated Credit Agreement, among the Company, the Subsidiary Co-Borrowers, the lenders party thereto and the Administrative Agent (the "Sixth Amendment"), pursuant to which those lenders electing to enter into the Sixth Amendment extended the expiration date for the revolving line of credit and the maturity date for the term loan by five years to May 3, 2021. Lenders holding revolving credit commitments aggregating $940.0 million elected to extend the expiration date for the revolving line of credit, and Lenders holding approximately $324.5 million of term loans (out of an aggregate outstanding term loan balance of approximately $330.0 million) elected to extend the term loan maturity date.

In addition, the Sixth Amendment amended the Credit Agreement to, among other things, (i) modify certain financial covenants to allow for the add-back of certain cash and non-cash charges, (ii) amend the total leverage ratio financial covenant to provide for a gradual reduction in the maximum permitted total leverage ratio commencing with the fiscal year ending March 31, 2018, (iii) increase the interest rate, commitment fee and letter of credit fee pricing provisions for the highest pricing tier, (iv) establish the interest rate, commitment fee and letter of credit fee pricing at the highest pricing tier until the Company delivers its compliance certificate for its fiscal year ending March 31, 2017, (v) increase the minimum revolver availability threshold test in connection with the Company making certain permitted investments, certain additional permitted dividends, permitted acquisitions and permitted payments of certain types of indebtedness, and (vi) decrease the maximum senior secured leverage ratio threshold test in connection with the Company making certain permitted investments, certain permitted dividends, permitted acquisitions and permitted payments of certain types of indebtedness during the period from the date of the Sixth Amendment until the Company delivers its compliance certificate for the fiscal year ending March 31, 2017.

The Credit Agreement contains representations, warranties, covenants and events of default customary for financings of this type including, without limitation, financial covenants under which the Company is obligated to maintain on a consolidated basis, as of the end of each fiscal quarter, a certain minimum interest coverage ratio and maximum senior secured leverage ratio.

The obligations under the Credit Agreement and related documents are secured by liens on substantially all assets of the Company and its domestic subsidiaries pursuant to a Second Amended and Restated Guarantee and Collateral Agreement, dated as of November 19, 2013, among the administrative agent, the Company and the subsidiaries of the Company party thereto.

Pursuant to the Credit Agreement, the Company can borrow, repay and re-borrow revolving credit loans, and cause to be issued letters of credit, in an aggregate principal amount not to exceed $850.0 million outstanding at any time. Our credit facilities bear interest at either: (i) LIBOR plus between 1.50% and 3.50%; (ii) the prime rate; or (iii) an overnight rate at the option of the Company. The applicable interest rate is based upon the Company's ratio of total indebtedness to earnings before interest, taxes, depreciation and amortization. In addition, the Company is required to pay a commitment fee of between 0.25% and 0.50% on the unused portion of the Credit Agreement. The Company's obligations under the Credit Agreement are guaranteed by the Company's domestic subsidiaries.

At September 30, 2017, there were $117.4 million in borrowings and $30.3 million in letters of credit outstanding under the Revolving Line of Credit provisions of the Credit Agreement, primarily to support insurance policies. At March 31, 2017, there were $30.0 million in borrowings and $27.2 million in letters of credit outstanding under the Revolving Line of Credit provisions of the Credit Agreement, primarily to support insurance policies. The level of unused borrowing capacity under the Revolving

Table of Contents

Line of Credit provisions of the Credit Agreement varies from time to time depending in part upon its compliance with financial and other covenants set forth in the related agreement. The Credit Agreement contains certain affirmative and negative covenants, including limitations on specified levels of indebtedness to earnings before interest, taxes, depreciation and amortization, and interest coverage requirements, and includes limitations on, among other things, liens, mergers, consolidations, sales of assets, and incurrence of debt. If an event of default were to occur under the Credit Agreement, the lenders would be entitled to declare all amounts borrowed under it immediately due and payable. The occurrence of an event of default under the Credit Agreement could also cause the acceleration of obligations under certain other agreements. The Company is currently in compliance with all such covenants. Although the Company does not anticipate any violations of the financial covenants, its ability to comply with these covenants is dependent upon achieving earnings and cash flow projections. As of September 30, 2017, the Company had borrowing capacity under this facility of $652.3 million after reductions for borrowings, letters of credit outstanding under the facility and consideration of covenant limitations.

The Company also had an interest rate swap agreement through November 2018 to reduce its exposure to interest on the variable rate portion of its long-term debt. On the date of inception, the Company designated the interest rate swap as a cash flow hedge in accordance with Financial Accounting Standards Board guidance on accounting for derivatives and hedges and linked the interest rate swap to the 2013 term loan. The Company formally assesses, both at the hedge's inception and on a quarterly basis, whether the derivative item is highly effective in offsetting changes in cash flows.

As of March 31, 2017, the interest rate swap agreement had a notional amount of $309.4 million. As of March 31, 2017, the interest rate swap agreement had a fair value of $0.5 million which was recorded in other noncurrent liabilities with an offset to other comprehensive income, net of applicable taxes (Level 2). The interest rate swap settled on a monthly basis when interest payments were made. These settlements occur through the maturity date.

In August 2017, the Company repaid the oustanding balance of the 2013 term loan. In conjunction with the repayment of the 2013 term loan, the Company terminated the interest rate swap receiving $0.3 million upon settlement.

Receivables securitization facility

In August 2008, the Company established its receivables securitization facility (the "Securitization Facility") by entering into a receivables purchase agreement, among the Company, as initial servicer, Triumph Receivables LLC, as seller, PNC Bank, National Association, as administrative agent, and the various purchasers and purchase agents from time to time party thereto.

In November 2014, the Company amended its Securitization Facility, increasing the purchase limit from $175.0 million to $225.0 million and extending the term through November 2017. In connection with the Securitization Facility, the Company sells on a revolving basis certain trade accounts receivable to Triumph Receivables, LLC, a wholly-owned special-purpose entity, which in turn sells a percentage ownership interest in the receivables to commercial paper conduits sponsored by financial institutions. The Company is the servicer of the trade accounts receivable under the Securitization Facility. As of June 30, 2017, the maximum amount available under the Securitization Facility was $225.0 million. Interest rates are based on LIBOR plus a program fee and a commitment fee. The program fee is 0.40% on the amount outstanding under the Securitization Facility. Additionally, the commitment fee is 0.40% on 100.00% of the maximum amount available under the Securitization Facility. At September 30, 2017, there was $88.8 million outstanding under the Securitization Facility. In connection with amending the Securitization Facility, the Company incurred approximately $0.3 million of financing costs. These costs, along with the $0.3 million of unamortized financing costs prior to the amendment, are being amortized over the life of the Securitization Facility. The Company secures its trade accounts

receivable, which are generally non-interest bearing, in transactions that are accounted for as borrowings pursuant to the Transfers and Servicing topic of the ASC 860. In November 2017, the Company amended the Securitization Facility decreasing the purchase limit from $225,000 to $125,000 and extending the term through November 2020. The Securitization Facility's net availability is not impacted by the borrowing capacity of the Credit Agreement.

The agreement governing the Securitization Facility contains restrictions and covenants, including limitations on the making of certain restricted payments, creation of certain liens, and certain corporate acts such as mergers, consolidations and the sale of all or substantially all of the Company's assets.

Receivables purchase agreement

On March 28, 2016, the Company entered into a Purchase Agreement ("Receivables Purchase Agreement") to sell certain accounts receivables to a financial institution without recourse. The Company is the servicer of the accounts receivable under the Receivables Purchase Agreement.

Senior notes due 2021

On February 26, 2013, the Company issued $375.0 million principal amount of 4.875% Senior Notes due 2021 (the "2021 Notes"). The 2021 Notes were sold at 100% of principal amount and have an effective interest yield of 4.875%. Interest on the 2021 Notes accrues at the rate of 4.875% per annum and is payable semiannually in cash in arrears on April 1 and October 1 of each year, commencing on October 1, 2013. In connection with the issuance of the 2021 Notes, the Company incurred approximately $6.3 million of costs, which are a direct deduction to the face amount of the note and are being amortized on the effective interest method over the term of the 2021 Notes.

The 2021 Notes are the Company's senior unsecured obligations and rank equally in right of payment with all of its other existing and future senior unsecured indebtedness and senior in right of payment to all of its existing and future subordinated indebtedness. The 2021 Notes are guaranteed on a full, joint and several basis by each of our domestic restricted subsidiaries that is a borrower under our credit facilities or that guarantees any of our debt or that of any of our domestic restricted subsidiaries under our credit facilities and in the future by any domestic restricted subsidiaries that are borrowers under any credit facility or that guarantee any of our debt or that of any of our domestic restricted subsidiaries incurred under any credit facility (the "Guarantor Subsidiaries").

The Company was permitted to redeem some or all of the 2021 Notes prior to April 1, 2017, by paying a "make-whole" premium. The Company may redeem some or all of the 2021 Notes on or after April 1, 2017, at specified redemption prices. In addition, prior to April 1, 2016, the Company was permitted redeem up to 35% of the 2021 Notes with the net proceeds of certain equity offerings at a redemption price equal to 104.875% of the aggregate principal amount plus accrued and unpaid interest, if any, subject to certain limitations set forth in the indenture governing the 2021 Notes (the "2021 Indenture").

The Company is obligated to offer to repurchase the 2021 Notes at a price of (i) 101% of their principal amount plus accrued and unpaid interest, if any, as a result of certain change-of-control events, and (ii) 100% of their principal amount plus accrued and unpaid interest, if any, in the event of certain asset sales. These restrictions and prohibitions are subject to certain qualifications and exceptions.

The 2021 Indenture contains covenants that, among other things, limit the Company's ability and the ability of any of the Guarantor Subsidiaries to (i) grant liens on its assets, (ii) make dividend payments, other distributions or other restricted payments, (iii) incur restrictions on the ability of the Guarantor Subsidiaries to pay dividends or make other payments, (iv) enter into sale and leaseback transactions, (v) merge, consolidate, transfer or dispose of substantially all of their assets, (vi) incur

Table of Contents

additional indebtedness, (vii) use the proceeds from sales of assets, including capital stock of restricted subsidiaries, and (viii) enter into transactions with affiliates.

During the quarter ended June 30, 2016, to ensure that the Company had full access to its credit facilities during fiscal 2017, the Company obtained approval from the holders of the 2021 Notes to amend the terms of the indenture to conform with the 2022 Notes (as defined below) which allows for a higher level of secured debt. Absent this consent, the Company would have been restricted as to the level of new borrowings under its credit facilities during fiscal 2017. As part of obtaining the consent, the Company paid the holders of the 2021 Notes $5.5 million, which is being amortized on the effective interest method over the remaining term of the 2021 Notes.

Further, to mitigate the risk of failing to obtain the consent and to ensure the Company had adequate liquidity through fiscal 2017, the Company chose to make a significant draw on its credit facilities in early April 2016, taking the outstanding balance to approximately $800.0 million. The Company paid down substantially all of the draw to its credit facilities upon receiving consent from the holders of the 2021 Notes in May 2016.

Senior notes due 2022

On June 3, 2014, the Company issued $300.0 million principal amount of 5.250% Senior Notes due 2022 (the "2022 Notes"). The 2022 Notes were sold at 100% of principal amount and have an effective interest yield of 5.250%. Interest on the 2022 Notes accrues at the rate of 5.250% per annum and is payable semiannually in cash in arrears on June 1 and December 1 of each year, commencing on December 1, 2014. In connection with the issuance of the 2022 Notes, the Company incurred approximately $5.0 million of costs, which are a direct deduction to the face amount of the note and are being amortized on the effective interest method over the term of the 2022 Notes.

The 2022 Notes are the Company's senior unsecured obligations and rank equally in right of payment with all of its other existing and future senior unsecured indebtedness and senior in right of payment to all of its existing and future subordinated indebtedness. The 2022 Notes are guaranteed on a full, joint and several basis by each of the Guarantor Subsidiaries.

The Company was permitted to redeem some or all of the 2022 Notes prior to June 1, 2017, by paying a "make-whole" premium. The Company may redeem some or all of the 2022 Notes on or after June 1, 2017, at specified redemption prices. In addition, prior to June 1, 2017, the Company was permitted to redeem up to 35% of the 2022 Notes with the net proceeds of certain equity offerings at a redemption price equal to 105.250% of the aggregate principal amount plus accrued and unpaid interest, if any, subject to certain limitations set forth in the indenture governing the 2022 Notes (the "2022 Indenture").

The Company is obligated to offer to repurchase the 2022 Notes at a price of (i) 101% of their principal amount plus accrued and unpaid interest, if any, as a result of certain change-of-control events and (ii) 100% of their principal amount plus accrued and unpaid interest, if any, in the event of certain asset sales. These restrictions and prohibitions are subject to certain qualifications and exceptions.

The 2022 Indenture contains covenants that, among other things, limit the Company's ability and the ability of any of the Guarantor Subsidiaries to (i) grant liens on its assets, (ii) make dividend payments, other distributions or other restricted payments, (iii) incur restrictions on the ability of the Guarantor Subsidiaries to pay dividends or make other payments, (iv) enter into sale and leaseback transactions, (v) merge, consolidate, transfer or dispose of substantially all of their assets, (vi) incur additional indebtedness, (vii) use the proceeds from sales of assets, including capital stock of restricted subsidiaries, and (viii) enter into transactions with affiliates.

DESCRIPTION OF NOTES

The Company will issue the Notes (as defined below) offered hereby under an Indenture dated as of August 17, 2017 among the Company, each Guarantor and U.S. Bank National Association, as Trustee (the "Indenture"). For purposes of this section of this offer to exchange, references to the "Company," "we," "us," "our" or similar terms refer solely to Triumph Group, Inc., and not its Subsidiaries. The 7.750% Senior Notes due 2025 offered hereby are referred to herein as the "Notes". We will issue the Notes in a registered exchange offer.

The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939 (as amended, the "Trust Indenture Act"). The following description is only a summary of the material provisions of the Indenture and the Notes. We urge you to read the Indenture and the Notes because those documents, not this description, define your rights as holders of the Notes. You may request copies of the Indenture at our address set forth under the heading "Where you can find more information." Certain defined terms used in this description but not defined below under "—Certain definitions" have the meanings assigned to them in the Indenture.

General

On August 17, 2017, we issued $500.0 million in aggregate principal amount of 7.750% Senior Notes due 2025 in a private transaction. The Company may issue additional notes (the "Additional Notes") under the Indenture, subject to the limitations described below under the covenant "Limitation on Incurrence of Debt." The Notes and any Additional Notes subsequently issued under the Indenture will be treated as a single class for all purposes of the Indenture, including, without limitation, waivers, consents, amendments, redemptions and offers to purchase;provided,however, that if any such Additional Notes are not fungible with the Notes for United States federal income tax purposes, they will be issued under a separate CUSIP number. Unless the context otherwise requires, for all purposes of the Indenture and this "Description of notes," references to the Notes include any Additional Notes actually issued.

Principal, maturity and interest

Interest on the Notes will accrue at 7.750% per annum. Interest on the Notes will be payable semi-annually in cash in arrears on February 15 and August 15, commencing on February 15, 2018. The Company will make each interest payment to the Holders of the Notes of record on the immediately preceding February 1 and August 1. Interest on the Notes will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from and including the Issue Date. Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months.

Principal of and premium, if any, and interest on the Notes will be payable, and the Notes will be exchangeable and transferable, at the office or agency of the Company maintained for such purposes, which, initially, will be the corporate trust office of the Trustee located at Two Liberty Place, 50 South 16th Street, Suite 2000, Philadelphia, Pennsylvania 19102;provided, however, that payment of interest may be made at the option of the Company by check mailed to the Person entitled thereto as shown on the security register. The Notes will be issued only in fully registered form without coupons, in denominations of $2,000 and any integral multiple of $1,000 in excess thereof. No service charge will be made for any registration of transfer, exchange or redemption of the Notes, except in certain circumstances for any tax or other governmental charge that may be imposed in connection therewith.

Guarantees

The Notes will be Guaranteed, on a full, joint and several basis, by the Guarantors pursuant to the Indenture (the "Note Guarantees"). On the Issue Date, each of our domestic Restricted Subsidiaries

Table of Contents

that (1) is a borrower under our Credit Agreement or (2) Guarantees any Debt of the Company or any of its domestic Restricted Subsidiaries, in each case incurred under our Credit Agreement, will Guarantee the Notes on a senior basis. After the Issue Date, the Notes will be guaranteed by any of our domestic Restricted Subsidiaries (other than any domestic Restricted Subsidiary that is a Receivable Subsidiary) that (1) becomes a borrower under any of our Credit Facilities or (2) Guarantees any of our Debt or any Debt of our domestic Restricted Subsidiaries, in each case incurred under any of our Credit Facilities. See "—Additional Note Guarantees."

The Indenture provides that the Obligations of a Guarantor under its Note Guarantee will be limited to the maximum amount as will result in the Obligations of such Guarantor under the Note Guarantee not to be deemed to constitute a fraudulent conveyance or fraudulent transfer under federal or state law. See "Risk factors—Fraudulent conveyance laws may permit courts to void the guarantors' guarantees of the Notes in specific circumstances, which would interfere with the payment under the guarantors' guarantees." As of the Issue Date, all of our Subsidiaries will be "Restricted Subsidiaries" other than Triumph Receivables, LLC, Triumph Group Charitable Foundation, Triumph Interiors, Ltd, Saygrove Actuation & Motion Control Limited and Airframe Spares & Logistics GmbH, each of which will be Unrestricted Subsidiaries on the Issue Date. Under the circumstances described below under the subheading "—Certain Covenants—Limitation on Creation of Unrestricted Subsidiaries," other of our Subsidiaries in the future may be designated as "Unrestricted Subsidiaries." Unrestricted Subsidiaries will not be subject to many of the restrictive covenants in the Indenture and will not Guarantee the Notes.

The Indenture provides that in the event of a sale or other transfer or disposition of all of the Capital Interests in any Guarantor to any Person that is not an Affiliate of the Company in compliance with the terms of the Indenture, the occurrence of any other transaction permissible under the Indenture pursuant to which such Guarantor ceases to be a Subsidiary, the sale or other transfer of all or substantially all the assets of a Guarantor (including by way of merger or consolidation) to a Person that is not an Affiliate of the Company in compliance with the terms of the Indenture, or the release of a Guarantor of all of its Guarantee obligations in respect of the Credit Facilities, then such Guarantor shall be deemed automatically and unconditionally released and discharged of any obligations under its Note Guarantee. At the request of the Company, the Company, such Guarantor and the Trustee will execute a supplemental indenture evidencing such release and discharge; provided that the Company delivers an Officer's Certificate to the Trustee certifying that the conditions to such release have been satisfied.

Not all of our Subsidiaries will Guarantee the Notes. For the four fiscal quarters, for the period ending September 30, 2017, the Company's non-Guarantor Subsidiaries had net sales of $366.2 million or 11.1% of our consolidated net sales, and Adjusted EBITDA of $26.3 million, or 8.1% of our Adjusted EBITDA and as of September 30, 2017, such non-Guarantor Subsidiaries had total assets of $817.5 million. As of September 30, 2017, such non-Guarantor Subsidiaries had $602.1 million of indebtedness and other liabilities. In the event of a bankruptcy, liquidation or reorganization of such non-Guarantor Subsidiaries, claims of creditors of such non-Guarantor Subsidiaries, including trade creditors, secured creditors and creditors holding Debt and Guarantees issued by those non-Guarantor Subsidiaries, and claims of preferred stockholders (if any) of those non-Guarantor Subsidiaries generally will have priority with respect to the assets of those non-Guarantor Subsidiaries over the claims of creditors of the Company, including Holders of the Notes.

•: equal in right of payment to any existing and future senior Debt of that Guarantor;
•: senior in right of payment to all existing and future Subordinated Obligations of that Guarantor; and
•: effectively subordinated to that Guarantor's secured Debt to the extent of the value of the assets securing such Debt, including the guarantee obligations of such Guarantor in respect of the Credit Agreement to the extent of the value of the collateral therefor.

Offers to purchase; open market purchases

We are not required to make any mandatory redemption or sinking fund payments with respect to the Notes. However, under certain circumstances, we may be required to offer to purchase Notes as described under the captions "—Change of Control" and "Certain Covenants—Limitation on Sales of Assets and Subsidiary Stock." We may at any time and from time to time purchase Notes in the open market or otherwise.

Optional redemption

The Notes may be redeemed, in whole or in part, at any time prior to August 15, 2020, at the option of the Company upon not less than 30 nor more than 60 days' prior notice mailed by first class mail (and/or, to the extent permitted by applicable procedures or regulations, electronically) to each Holder's registered address, at a Redemption Price equal to 100% of the principal amount of the Notes to be redeemed plus the Applicable Premium, plus accrued and unpaid interest, if any, to, but not including, the applicable redemption date (subject to the right of registered Holders of the Notes on a relevant record date to receive interest due on a relevant interest payment date).

In addition, the Notes are subject to redemption, at the option of the Company, in whole or in part, at any time on or after August 15, 2020, upon not less than 30 nor more than 60 days' notice at the following Redemption Prices (expressed as percentages of the principal amount to be redeemed) set forth below, plus accrued and unpaid interest, if any, to, but not including, the redemption date (subject to the right of registered Holders of the Notes on a relevant record date to receive interest

due on a relevant interest payment date), if redeemed during the 12-month period beginning on August 15 of the years indicated:

Year

2020	105.813	%
2021	103.875	%
2022	101.938	%
2023 and thereafter	100.000	%

In addition to the optional redemption provisions of the Notes in accordance with the provisions of the preceding paragraphs, prior to August 15, 2020, the Company may at its option, with the net proceeds of one or more Qualified Equity Offerings, redeem up to 35% of the aggregate principal amount of the outstanding Notes (including Additional Notes) at a Redemption Price equal to 107.75% of the principal amount thereof, plus accrued and unpaid interest thereon, if any, to, but not including, the date of redemption (subject to the right of registered Holders of the Notes of record on the relevant record date to receive interest due on a relevant interest payment date); provided that at least 65% of the principal amount of Notes (including Additional Notes) issued under the Indenture remains outstanding immediately after the occurrence of any such redemption (excluding Notes held by the Company or its Subsidiaries) and that any such redemption occurs within 90 days following the closing of any such Qualified Equity Offering.

Any notice of redemption may, at the Company's discretion, be subject to one or more conditions precedent, including completion of a Qualified Equity Offering or other corporate event.

Selection

If less than all of the Notes are to be redeemed, the Trustee will select the Notes or portions thereof to be redeemed by lot, pro rata or by any other method the Trustee shall deem fair and appropriate (subject to the Depository Trust Company procedures).

No Notes of $2,000 or less shall be redeemed in part. Notices of redemption shall be mailed by first class mail (and/or, to the extent permitted by applicable procedures or regulations, electronically) at least 30 but no more than 60 days before the redemption date to each Holder of Notes to be redeemed at its registered address. If any Note is to be redeemed in part only, the notice of redemption that relates to that Note shall state the portion of the principal amount thereof to be redeemed. A new Note in principal amount equal to the unredeemed portion of the original Note, if any, will be issued in the name of the Holder thereof upon cancellation of the original Note. Notes called for redemption become due on the date fixed for redemption. On and after the redemption date, interest ceases to accrue on Notes or portions of them called for redemption.

Change of control

Upon the occurrence of a Change of Control, the Company will make an Offer to Purchase all of the outstanding Notes at a Purchase Price in cash equal to 101% of the principal amount tendered, together with accrued interest, if any, to but not including the Purchase Date; provided that if the Company has exercised its right to redeem all of the Notes as described above under the caption "—Optional Redemption" prior to the time the Company would be required to make an Offer to Purchase, the Company shall not be required to make such Offer to Purchase. For purposes of the foregoing, an Offer to Purchase shall be deemed to have been made if (i) within 60 days following the date of the consummation of a transaction or series of transactions that constitutes a Change of Control, the Company commences an Offer to Purchase for all outstanding Notes at the Purchase Price and (ii) all Notes properly tendered pursuant to the Offer to Purchase are purchased on the terms of such Offer to Purchase.

Table of Contents

Although there is a limited body of case law interpreting the phrase "all or substantially all," as used in the definition of "Change of Control," there is no precise established definition of the phrase under applicable law. As a consequence, in certain circumstances, there may be a degree of uncertainty as to whether a particular transaction would involve a disposition of "all or substantially all" of the assets of the Company. It may be unclear as to whether a Change of Control has occurred and whether a Holder of Notes may require the Company to make an Offer to Purchase the Notes as described above.

Subject to the limitations discussed below, the Company could, in the future, enter into a highly leveraged transaction, reorganization, restructuring, merger or similar transaction, that would not constitute a Change of Control under the Indenture, but that could increase the amount of Debt outstanding at such time or otherwise affect the Company's capital structure or credit ratings. The definition of Change of Control may be amended or modified with the written consent of a majority in aggregate principal amount of outstanding Notes. See "—Amendment, Supplement and Waiver." The Company will be required to comply with the requirements of Rule 14e-1 under the Exchange Act and any other applicable securities laws or regulations in connection with any repurchase of the Notes as described above. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control provisions of the Indenture, the Company will comply with the applicable securities laws and regulations and will be deemed to have complied with its obligations under the Change of Control provisions of the Indenture by virtue of such compliance.

The Company will not be required to make an Offer to Purchase upon a Change of Control if (i) a third party makes such Offer to Purchase contemporaneously with or upon a Change of Control in the manner, at the times and otherwise in compliance with the requirements of the Indenture and purchases all Notes validly tendered and not withdrawn under such Offer to Purchase or (ii) a notice of redemption has been given pursuant to the Indenture as described above under the caption "—Optional Redemption."

Holders of the Notes may not be entitled to require the Company to purchase their Notes in certain circumstances involving a significant change in the composition of the Board of Directors of the Company, including in connection with a proxy contest, where the Company's Board of Directors initially publicly opposes the election of a dissident slate of directors, but subsequently approves such directors for the purposes of the Indenture. This may result in a change in the composition of the Board of Directors of the Company that, but for such subsequent approval, would have otherwise constituted a Change of Control requiring a repurchase offer under the terms of the Indenture.

The Company's ability to repurchase Notes pursuant to an Offer to Purchase may be limited by a number of factors. The occurrence of certain of the events that constitute a Change of Control would constitute a default under the Credit Agreement. In addition, certain events that may constitute a change of control under the Credit Agreement and cause a default under those agreements may not constitute a Change of Control under the Indenture. Future Debt of the Company and its Subsidiaries may also contain prohibitions of certain events that would constitute a Change of Control or require such Debt to be repurchased upon a Change of Control. Moreover, the exercise by the holders of their right to require the Company to repurchase the Notes could cause a default under such Debt, even if the Change of Control itself does not, due to the financial effect of such repurchase on the Company. Finally, the Company's ability to pay cash to the holders upon a repurchase may be limited by the Company's then existing financial resources. There can be no assurance that sufficient funds will be available when necessary to make any required repurchases.

In the event that at the time of a Change of Control the terms of the Credit Agreement restrict or prohibit the repurchase of Notes as contemplated in the Indenture, then prior to the electronic delivery or mailing of the Offer to Purchase required in connection with a Change of Control but in any event within 30 days following any Change of Control, the Company shall (i) repay in full all Debt under the

Table of Contents

applicable Credit Agreement or, if doing so will allow the purchase of Notes, offer to repay in full all such Debt and repay such Debt of each lender who has accepted such offer, or (ii) obtain the requisite consent under the Credit Agreement to permit the repurchase of the Notes as provided in the Indenture.

In addition, an Offer to Purchase may be made in advance of a Change of Control, conditional upon the occurrence of such Change of Control, if a definitive agreement is in place for the Change of Control at the time of launching the Offer to Purchase.

Certain covenants

Set forth below are certain covenants contained in the Indenture:

During any period of time (a "Suspension Period") that: (i) the Notes have Investment Grade Ratings from both Rating Agencies and (ii) no Default or Event of Default has occurred and is continuing under the Indenture (the occurrence of the events described in the foregoing clauses (i) and (ii) being collectively referred to as a "Covenant Suspension Event"), the Company and its Restricted Subsidiaries will not be subject to the following provisions of the Indenture (collectively, the "Suspended Covenants"), and during a Suspension Period but prior to the repayment, repurchase, retirement or redemption of all of the outstanding principal amount of the Notes or defeasance or satisfaction and discharge of the indenture governing the Notes (collectively, the "Satisfaction of the Notes"), the Company may not designate any of its Subsidiaries as Unrestricted Subsidiaries unless the Company could have designated such Subsidiaries as Unrestricted Subsidiaries in compliance with the Indenture assuming the covenants set forth below had not been suspended:

(a): "—Limitation on Incurrence of Debt;"
(b): "—Limitation on Restricted Payments;"
(c): "—Limitation on Dividend and Other Payment Restrictions Affecting Restricted Subsidiaries;"
(d): "—Limitation on Asset Sales;"
(e): "—Limitation on Transactions with Affiliates;" and
(f): clause (iii) of the first paragraph of "—Consolidation, Merger, Conveyance, Transfer or Lease."

In the event that the Company and its Restricted Subsidiaries are not subject to the Suspended Covenants with respect to the Notes for any Suspension Period and, subsequently, (x) either one or both Rating Agencies withdraws its rating or downgrades the rating assigned to the Notes below the required Investment Grade Rating or (y) the Company or any of its affiliates enters into an agreement to effect a transaction that would result in a Change of Control and either one or both Rating Agencies indicate that if consummated, such transaction (alone or together with any related recapitalization or refinancing transactions) would cause such Rating Agency to withdraw its Investment Grade Rating or downgrade the ratings assigned to the Notes below an Investment Grade Rating, and such event in clause (x) or (y) occurs prior to the Satisfaction of the Notes (such date of withdrawal or downgrade in clause (x) or (y), a "Reinstatement Date"), then the Company and its Restricted Subsidiaries will after the Reinstatement Date again be subject to the Suspended Covenants with respect to future events for the benefit of the Notes (unless and until a Suspension Event again exists) until the Satisfaction of the Notes.

On the Reinstatement Date, all Debt incurred during a Suspension Period will be classified as having been Incurred or issued pursuant to the first paragraph of "—Limitation on Incurrence of Debt" below or, at the Company's option, one of the clauses set forth in the definition of "Permitted Debt" (to the extent such Debt would be permitted to be Incurred thereunder as of the Reinstatement

Table of Contents

Date and after giving effect to Debt Incurred prior to the Suspension Period and outstanding on the Reinstatement Date) and subject to the covenant described below under "—Limitation on Incurrence of Debt." To the extent such Debt would not be so permitted to be Incurred pursuant to the covenant described below under "—Limitation on Incurrence of Debt," such Debt will be deemed to have been outstanding on the Issue Date, so that it is classified as permitted under clause (iv) of the definition of Permitted Debt.

Calculations made after the Reinstatement Date of the amount available to be made as Restricted Payments under the covenant described below under "—Limitation on Restricted Payments" will be made as though such covenant had been in effect from the Issue Date and throughout the Suspension Period. Accordingly, Restricted Payments made during the Suspension Period will reduce the amount available to be made as Restricted Payments under the first paragraph of the covenant described below under "—Restricted Payments" to the extent provided therein.

Notwithstanding that the Suspended Covenants may be reinstated, no Default or Event of Default will be deemed to have occurred as a result of a failure to comply with the Suspended Covenants during a Suspension Period (or on the Reinstatement Date or after a Suspension Period based solely on events that occurred during the Suspension Period).

The Company will provide prompt written notice to the Trustee of any Covenant Suspension Event and any Reinstatement Date.

There can be no assurance that the Notes will ever achieve or maintain an Investment Grade Rating.

Limitation on incurrence of debt

The Company will not, and will not permit any of its Restricted Subsidiaries to, Incur any Debt (including Acquired Debt);provided that the Company and any of its Restricted Subsidiaries may Incur Debt (including Acquired Debt) if, immediately after giving effect to the Incurrence of such Debt and the receipt and application of the proceeds therefrom, (a) the Consolidated Fixed Charge Coverage Ratio of the Company and its Restricted Subsidiaries, determined on a pro forma basis as if any such Debt (including any other Debt being Incurred contemporaneously), and any other Debt Incurred since the beginning of the Four Quarter Period (as defined below) had been Incurred and the proceeds thereof had been applied at the beginning of the Four Quarter Period, and any other Debt repaid since the beginning of the Four Quarter Period had been repaid at the beginning of the Four Quarter Period, would be greater than 2.00:1 and (b) no Event of Default shall have occurred and be continuing at the time or as a consequence of the Incurrence of such Debt;provided further, that Restricted Subsidiaries that are not Guarantors may not Incur any Debt pursuant to this paragraph if the Secured Leverage Ratio of the Company and its Restricted Subsidiaries, determined on a pro forma basis as if any such Debt (including any other Debt being Incurred contemporaneously), and any other Debt Incurred since the beginning of the Four Quarter Period (as defined below) had been Incurred and the proceeds thereof had been applied at the beginning of the Four Quarter Period, and any other Debt repaid since the beginning of the Four Quarter Period had been repaid at the beginning of the Four Quarter Period, would be greater than 3.00:1.

Notwithstanding the immediately preceding paragraph, the Company and its Restricted Subsidiaries may Incur Permitted Debt.

For purposes of determining any particular amount of Debt under this "Limitation on Incurrence of Debt" covenant, Guarantees or obligations with respect to letters of credit supporting Debt otherwise included in the determination of such particular amount shall not be included. For purposes of determining compliance with this "Limitation on Incurrence of Debt" covenant, in the event that an item of Debt meets the criteria of more than one of the types of Debt described above, including

Table of Contents

categories of Permitted Debt and under part (a) in the first paragraph of this "Limitation on Incurrence of Debt" covenant, the Company, in its sole discretion, shall classify, and from time to time may reclassify, all or any portion of such item of Debt,provided that Debt Incurred under the Credit Facilities on the Issue Date shall at all times be treated as Incurred pursuant to clause (i) of the definition of "Permitted Debt". The accrual of interest, the accretion or amortization of original issue discount and the payment of interest on Debt in the form of additional Debt or payment of dividends on Capital Interests in the forms of additional shares of Capital Interests with the same terms will not be deemed to be an Incurrence of Debt or issuance of Capital Interests for purposes of this covenant.

Limitation on restricted payments

The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, make any Restricted Payment unless, at the time of and after giving effect to the proposed Restricted Payment:

(b) after giving effect to such Restricted Payment on a pro forma basis, the Company would be permitted to Incur at least $1.00 of additional Debt pursuant to the provisions described in the first paragraph under the "Limitation on Incurrence of Debt" covenant; and

(2) 100% of the aggregate net proceeds (including the Fair Market Value of property other than cash) received by the Company subsequent to the Issue Date either (i) as a contribution to its common equity capital or (ii) from the issuance and sale (other than to a Subsidiary) of its Qualified Capital Interests (excluding any Qualified Capital Interests issued in connection with the Company's acquisition of Vought Aircraft Industries, Inc.), including Qualified Capital Interests issued upon the conversion or exchange of Debt or Redeemable Capital Interests of the Company, and from the exercise of options, warrants or other rights to purchase such Qualified Capital Interests (other than, in each case, Capital Interests or Debt sold to a Subsidiary of the Company), plus

(3) 100% of the net reduction in Investments (other than Permitted Investments), made by the Company or any Restricted Subsidiary subsequent to the Issue Date, in any Person, resulting from (i) payments of interest on Debt, dividends, repayments of loans or advances, or any sale or disposition of such Investments (but only to the extent such items are not included in the calculation of Consolidated Net Income), or (ii) the redesignation of an Unrestricted Subsidiary as a Restricted Subsidiary (or the causing of a Person that is not a Subsidiary to become a Restricted Subsidiary), not to exceed in the case of any Person the amount of Investments previously made by the Company or any Restricted Subsidiary in such Person subsequent to the Issue Date.

Notwithstanding the foregoing provisions, the Company and its Restricted Subsidiaries may take the following actions,provided that, at the time of and after giving effect to the proposed Restricted

(i) the payment of any dividend on Capital Interests in the Company or a Restricted Subsidiary or the consummation of any irrevocable redemption within 60 days after declaration thereof or the giving of such irrevocable notice, as applicable, if, at the declaration date or notice thereof, such payment was permitted by the foregoing provisions of this covenant;

(v) repurchase of Capital Interests deemed to occur upon the exercise of stock options, warrants or other convertible or exchangeable securities or the vesting of restricted stock units;

(x) the payment of regular cash quarterly dividends on the Company's common stock not to exceed $15.0 million in any calendar year; and

(xi) other Restricted Payments not in excess of $50.0 million in the aggregate since the Issue Date.

If the Company makes a Restricted Payment which, at the time of the making of such Restricted Payment, in the good faith determination of the Company, would be permitted under the requirements of the Indenture, such Restricted Payment shall be deemed to have been made in compliance with the Indenture notwithstanding any subsequent adjustment made in good faith to the Company's financial statements affecting Consolidated Net Income.

Limitation on liens

The Company will not, and will not permit any of its Restricted Subsidiaries to create, incur, assume or otherwise cause or suffer to exist or become effective any Lien of any kind securing Debt (other than Permitted Liens) upon any of their property or assets, now owned or hereafter acquired, unless all payments due under the Indenture and the Notes are secured on an equal and ratable basis with the obligations so secured (or in the case of Subordinated Obligations, prior or senior thereto, with the same relative priority as the Notes shall have with respect to such Subordinated Obligations) until such time as such obligations are no longer secured by a Lien. For purposes of this covenant, the Receivables Transaction Amount relating to any Qualified Receivables Transaction shall be deemed to be Debt secured by a Lien on the applicable accounts receivable and related assets and such accounts receivable and related assets shall be deemed to be assets of the originator thereof.

(e) customary provisions restricting subletting or assignment of any lease, contract, or license of the Company or any Restricted Subsidiary or provisions in agreements that restrict the assignment of such agreement or any rights thereunder;

(o) any other agreement governing Debt entered into after the Issue Date that contains encumbrances and restrictions that are not materially more restrictive with respect to any Restricted Subsidiary than those in effect on the Issue Date with respect to that Restricted Subsidiary pursuant to agreements in effect on the Issue Date.

Limitation on asset sales

The Company will not, and will not permit any of its Restricted Subsidiaries to, consummate an Asset Sale unless:

(1) the Company (or the Restricted Subsidiary, as the case may be) receives consideration at the time of the Asset Sale at least equal to the Fair Market Value (such Fair Market Value to be determined at the time of contractually agreeing to such Asset Sale) of the assets or Capital Interests issued or sold or otherwise disposed of; and

(2) at least 75% of the consideration received in the Asset Sale by the Company or such Restricted Subsidiary is in the form of cash or Eligible Cash Equivalents. For purposes of this provision, each of the following will be deemed to be cash:

(b) any securities, notes or other obligations received by the Company or any such Restricted Subsidiary from such transferee that are converted by the Company or such Restricted Subsidiary into cash within 180 days of their receipt to the extent of the cash received in that conversion.

Table of Contents

Within 360 days after the receipt of any Net Cash Proceeds from an Asset Sale, the Company (or the applicable Restricted Subsidiary, as the case may be) may apply such Net Cash Proceeds at its option:

(1) to prepay, repay, redeem or purchase any secured Debt (other than Subordinated Obligations) of the Company or any Restricted Subsidiary and cause such Debt to be permanently retired and the related commitment (if any) to be permanently reduced in an amount equal to the principal amount so prepaid, repaid, redeemed or repurchased;

(2) to prepay, repay, redeem or purchase any unsecured Debt (other than Subordinated Obligations) of the Company or any Restricted Subsidiary and cause such Debt to be permanently retired and the related commitment (if any) to be permanently reduced in an amount equal to the principal amount so prepaid, repaid, redeemed or repurchased; provided that to the extent the Company repays any such Debt, the Company shall equally and ratably repay the Notes as provided under the caption "—Optional Redemption," through open-market purchases (to the extent such purchases are at or above 100% of the principal amount thereof) or by making an Offer to Purchase (in accordance with the procedures set forth below relating to Asset Sales) to all Holders of Notes to purchase their Notes at 100% of the principal amount thereof, plus accrued but unpaid interest to the date of purchase;

(3) to acquire all or substantially all of the assets of, or any Capital Interests of, another Permitted Business, if, after giving effect to any such acquisition of Capital Interests, the Permitted Business is or becomes a Restricted Subsidiary of the Company;

(4) to make a capital expenditure in or that is used or useful (as determined in the good faith judgment of the Company) in a Permitted Business or to make expenditures for maintenance, repair or improvement of existing properties and assets in accordance with the provisions of the Indenture;

(5) to acquire other assets that are not classified as current assets under GAAP and that are used or useful (as determined in the good faith judgment of the Company) in a Permitted Business; or

(6) any combination of the foregoing.

Any Net Cash Proceeds from Asset Sales that are not applied or invested as provided in the preceding paragraph of this covenant will constitute "Excess Proceeds." When the aggregate amount of Excess Proceeds exceeds $25.0 million, the Company will, within 30 days, make an Offer to Purchase to all Holders of Notes (on apro rata basis to each series of Notes), and to all holders of other Debt rankingpari passu with the Notes containing provisions similar to those set forth in the Indenture with respect to assets sales, in an amount equal to the Excess Proceeds. The offer price in any Offer to Purchase will be equal to 100% of the principal amount plus accrued and unpaid interest to the date of purchase, and will be payable in cash. If any Excess Proceeds remain after consummation of an Offer to Purchase; the Company may use those funds for any purpose not otherwise prohibited by the Indenture and they will no longer constitute Excess Proceeds. If the aggregate principal amount of Notes and otherpari passu Debt tendered into such Offer to Purchase exceeds the amount of Excess Proceeds, the Trustee will select the Notes to be purchased on a pro rata basis among each series. Upon completion of each Offer to Purchase, the amount of Excess Proceeds will be reset at zero.

Pending the final application of any Net Cash Proceeds pursuant to this covenant, such Net Cash Proceeds may be applied temporarily to reduce Indebtedness outstanding under a revolving credit facility or may otherwise be invested in any manner not prohibited by the Indenture.

The Company will comply with the requirements of Rule 14e-1 under the Exchange Act and any other applicable securities laws and regulations thereunder to the extent those laws and regulations are

Table of Contents

applicable in connection with each repurchase of Notes pursuant to an Offer to Purchase. To the extent that the provisions of any securities laws or regulations conflict with the Asset Sale provisions of the Indenture, the Company will comply with the applicable securities laws and regulations and will be deemed to have complied with its obligations under the Asset Sale provisions of the Indenture by virtue of such compliance.

The agreements governing our other Debt contain, and future agreements may contain, restrictions on the conduct of our business, including restrictions on our ability to conduct Asset Sales and on our ability to apply the proceeds of any permitted Asset Sale to payment of the Notes.

Limitation on transactions with affiliates

The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, make any payment to, or sell, lease, transfer or otherwise dispose of any of its properties or assets to, or purchase any property or assets from, or enter into or make or amend any transaction or series of related transactions, contract, agreement, loan, advance or Guarantee with, or for the benefit of, any Affiliate of the Company (each of the foregoing, an "Affiliate Transaction"), unless:

(i) such Affiliate Transaction is on terms that are not materially less favorable to the Company or the relevant Subsidiary than those that could reasonably have been obtained in a comparable arm's length transaction by the Company or such Subsidiary with a Person who is not an Affiliate;

(ii) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $10.0 million, the Company delivers to the Trustee a resolution adopted in good faith by the majority of the Board of Directors of the Company approving such Affiliate Transaction and set forth in an Officer's Certificate certifying that such Affiliate Transaction complies with clause (i) above; and

(iii) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $25.0 million, the Company must obtain and deliver to the Trustee a written opinion of a nationally recognized investment banking, accounting or appraisal firm (an "Independent Financial Advisor") stating that the transaction is fair to the Company or such Restricted Subsidiary, as the case may be, from a financial point of view.

The foregoing limitation does not limit, and shall not apply to:

(6) any contribution of capital to the Company;

(7) transactions permitted by, and complying with, the provisions of the Indenture described below under "—Consolidation, Merger, Conveyance, Transfer or Lease";

(9) transactions with customers, clients, suppliers or purchasers or sellers of goods or services, in each case, in the ordinary course of business and consistent with past practice and on terms that are not materially less favorable to the Company or such Restricted Subsidiary, as the case may be, as determined in good faith by the Company, than those that could be obtained in a comparable arm's length transaction with a Person that is not an Affiliate of the Company; and

(10) transactions effected as part of a Qualified Receivables Transaction.

Limitation on sale and leaseback transactions

Each Note Guarantee will state that it will be limited to an amount not to exceed the maximum amount that can be Guaranteed by that Restricted Subsidiary without rendering the Guarantee, as it relates to such Restricted Subsidiary, voidable under applicable law relating to fraudulent conveyance or fraudulent transfer or similar laws affecting the rights of creditors generally.

Each Guarantee will be released in accordance with the provisions of the indenture described under "—Guarantees" above.

Company is not continuing) could Incur $1.00 of additional Debt under the provisions described in the first paragraph of "—Limitation on Incurrence of Debt"; and

(iv) the Company delivers, or causes to be delivered, to the Trustee, in form satisfactory to the Trustee, an Officer's Certificate and an opinion of counsel, each stating that such consolidation, merger, sale, conveyance, assignment, transfer, lease or other disposition complies with the requirements of the Indenture.

Notwithstanding the foregoing, failure to satisfy the requirements of the preceding clauses (ii) and (iii) will not prohibit:

(1) a merger between the Company and a Restricted Subsidiary that is a wholly owned Subsidiary of the Company; or

(2) a merger between the Company and an Affiliate incorporated solely for the purpose of converting the Company into a Person organized under the laws of the United States or any political subdivision or state thereof (other than its then-current state of organization) or for the purpose of changing its form of organization; so long as, in each case, the amount of Debt of the Company and its Restricted Subsidiaries is not increased thereby.

For all purposes of the Indenture and the Notes, Subsidiaries of any Surviving Entity will, upon such transaction or series of transactions, become Restricted Subsidiaries or Unrestricted Subsidiaries as provided pursuant to the Indenture and all Debt, and all Liens on property or assets, of the Surviving Entity and its Subsidiaries that was not Debt, or were not Liens on property or assets, of the Company and its Subsidiaries immediately prior to such transaction or series of transactions shall be deemed to have been Incurred upon such transaction or series of transactions.

Upon any transaction or series of transactions that are of the type described in, and are effected in accordance with, the conditions described in the immediately preceding paragraphs, the Surviving Entity (if other than the Company) shall succeed to, and be substituted for, and may exercise every right and power of, the Company, under the Indenture with the same effect as if such Surviving Entity had been named as the Company therein; and when a Surviving Entity duly assumes all of the obligations and covenants of the Company pursuant to the Indenture and the Notes, except in the case of a lease of all or substantially all of the Company's assets, the predecessor Person shall be relieved of all such obligations.

Limitation on business activities

The Company will not, and will not permit any Restricted Subsidiary to, engage in any business other than a Permitted Business.

Payments for consent

The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, pay or cause to be paid any consideration to or for the benefit of any Holder of Notes for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of the Indenture or the Notes unless such consideration is offered to be paid and is paid to all Holders of the Notes that consent, waive or agree to amend in the time frame set forth in the solicitation documents relating to such consent, waiver or agreement.

Events of default

(1) Each of the following is an "Event of Default" under the Indenture:

(2) default in the payment in respect of the principal of (or premium, if any, on) any Note when due and payable (whether at Stated Maturity or upon repurchase, acceleration, optional redemption or otherwise);

(3) default in the payment of any interest upon any Note when it becomes due and payable, and continuance of such default for a period of 30 days;

(4) except as permitted by the Indenture, any Note Guarantee of any Significant Subsidiary required to be a Guarantor pursuant to the Indenture (or any group of Restricted Subsidiaries required to be Guarantors pursuant to the Indenture that, taken together, would constitute a Significant Subsidiary), shall for any reason cease to be, or it shall be asserted by any Guarantor or the Company not to be, in full force and effect and enforceable in accordance with its terms;

(5) default in the performance, or breach, of any covenant or agreement (including the Company's obligations described under "—Change of Control" above) of the Company or any Guarantor in the Indenture (other than a covenant or agreement a default in whose performance or whose breach is specifically addressed in clauses (1), (2) or (3) above), and continuance of such default or breach for a period of 60 days after written notice thereof has been given to the Company by the Trustee or to the Company and the Trustee by the Holders of at least 25% in aggregate principal amount of the outstanding Notes;

(6) a default or defaults under any bonds, debentures, notes or other evidences of Debt (other than the Notes) by the Company or any Restricted Subsidiary having, individually or in the aggregate, a principal or similar amount outstanding of at least $50.0 million, whether such Debt now exists or shall hereafter be created, which default or defaults (A) shall have resulted in the acceleration of the maturity of such Debt prior to its express maturity or (B) shall constitute a failure to pay principal of at least $50.0 million on such Debt when due and payable after the expiration of any applicable grace period with respect thereto;

(7) the entry against the Company or any Restricted Subsidiary that is a Significant Subsidiary of a final judgment or final judgments for the payment of money in an aggregate amount in excess of $50.0 million, by a court or courts of competent jurisdiction, which judgments remain undischarged, unwaived, unstayed, unbonded or unsatisfied for a period of 60 consecutive days; or

(8) certain events of bankruptcy, insolvency or reorganization of the Company or any Significant Subsidiary (or any group of Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary).

If an Event of Default (other than an Event of Default specified in clause (7) above with respect to the Company) occurs and is continuing, then and in every such case the Trustee or the Holders of not less than 25% in aggregate principal amount of the outstanding Notes may declare the principal of the Notes and any accrued interest on the Notes to be due and payable immediately by a notice in writing to the Company (and to the Trustee if given by Holders); provided, however, that after such acceleration, but before a judgment or decree based on acceleration, the Holders of a majority in aggregate principal amount of the outstanding Notes may, under certain circumstances, rescind and annul such acceleration if all Events of Default (other than the nonpayment of accelerated principal of, premium, if any, or interest on the Notes) have been cured or waived as provided in the Indenture.

In the event of a declaration of acceleration of the Notes solely because an Event of Default described in clause (5) above has occurred and is continuing, the declaration of acceleration of the Notes shall be automatically rescinded and annulled if the event of default or payment default triggering such Event of Default pursuant to clause (5) shall be remedied or cured by the Company or

Table of Contents

a Restricted Subsidiary of the Company or waived by the holders of the relevant Debt within 20 business days after the declaration of acceleration with respect thereto and if the rescission and annulment of the acceleration of the Notes would not conflict with any judgment or decree of a court of competent jurisdiction obtained by the Trustee for the payment of amounts due on the Notes.

If an Event of Default specified in clause (7) above occurs with respect to the Company, the principal of and any accrued interest on the Notes then outstanding shall ipso facto become immediately due and payable without any declaration or other act on the part of the Trustee or any Holder. For further information as to waiver of defaults, see "—Amendment, Supplement and Waiver." The Trustee may withhold from Holders notice of any Default (except Default in payment of principal of, premium, if any, and interest) if the Trustee determines that withholding notice is in the best interests of the Holders.

No Holder of any Note will have any right to institute any proceeding with respect to the Indenture or for any remedy thereunder, unless such Holder shall have previously given to the Trustee written notice of a continuing Event of Default and unless also the Holders of at least 25% in aggregate principal amount of the outstanding Notes shall have made written request to the Trustee, and provided indemnity reasonably satisfactory to the Trustee, to institute such proceeding as Trustee, and the Trustee shall not have received from the Holders of a majority in aggregate principal amount of the outstanding Notes a direction inconsistent with such request and shall have failed to institute such proceeding within 60 days. Such limitations do not apply, however, to a suit instituted by a Holder of a Note directly (as opposed to through the Trustee) for enforcement of payment of the principal of (and premium, if any) or interest on such Note on or after the respective due dates expressed in such Note.

The Company will be required to furnish to the Trustee annually a statement as to the performance of certain obligations under the Indenture and as to any default in such performance. The Company also is required to notify the Trustee within five Business Days after it becomes aware of the occurrence of any Default or Event of Default.

Amendment, supplement and waiver

Without the consent of any Holders, the Company, the Guarantors and the Trustee, at any time and from time to time, may enter into one or more indentures supplemental to the Indenture for any of the following purposes:

Table of Contents

(10) to conform the text of the Indenture or the Notes to any provision of this "Description of Notes" to the extent that the Trustee has received an Officer's Certificate stating that such text constitutes an unintended conflict with the description of the corresponding provision in this "Description of Notes";

(11) to effect or maintain the qualification of the Indenture under the Trust Indenture Act;

(12) to secure the Notes; or

(13) to provide for the issuance of exchange securities which shall have terms substantially identical in all respects to the Notes (except that the transfer restrictions contained in the Notes shall be modified or eliminated as appropriate) and which shall be treated, together with any outstanding Notes, as a single class of securities.

With the consent of the Holders of not less than a majority in aggregate principal amount of the outstanding Notes (including consents obtained in connection with a purchase of, or tender offer or exchange offer for, Notes), the Company, the Guarantors and the Trustee may enter into an indenture or indentures supplemental to the Indenture for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Indenture or the Notes or of modifying in any manner the rights of the Holders of the Notes under the Indenture, including the definitions therein;provided, however, that no such supplemental indenture shall, without the consent of the Holder of each outstanding Note affected thereby:

(1) change the Stated Maturity of any Note or of any installment of interest on any Note, or reduce the amount payable in respect of the principal thereof or the rate of interest thereon or any premium payable thereon, or reduce the amount that would be due and payable on acceleration of the maturity thereof, or change the place of payment where, or the coin or currency in which, any Note or any premium or interest thereon is payable, or impair the right to institute suit for the enforcement of any such payment on or after the Stated Maturity thereof, or change the date on which any Notes may be subject to redemption or reduce the Redemption Price therefor;

(2) reduce the percentage in aggregate principal amount of the outstanding Notes, the consent of whose Holders is required for any such supplemental indenture, or the consent of whose Holders is required for any waiver (of compliance with certain provisions of the Indenture or certain defaults thereunder and their consequences) provided for in the Indenture;

(3) modify the obligations of the Company to make Offers to Purchase upon a Change of Control or from the Excess Proceeds of Asset Sales if such modification is made after the time that the Company is required to make an Offer to Purchase in connection with a Change of Control or Asset Sale;

(4) modify or change any provision of the Indenture affecting the ranking of the Notes or any Note Guarantee in a manner adverse to the Holders of the Notes;

(5) modify any of the provisions of this paragraph or provisions relating to waiver of defaults or certain covenants, except to increase any such percentage required for such actions or to provide that certain other provisions of the Indenture cannot be modified or waived without the consent of the Holder of each outstanding Note affected thereby; or

Table of Contents

(6) release any Note Guarantees required to be maintained under the Indenture (other than in accordance with the terms of the Indenture).

The Holders of not less than a majority in aggregate principal amount of the outstanding Notes may on behalf of the Holders of all the Notes waive any past default under the Indenture and its consequences, except a default:

(1) in any payment in respect of the principal of (or premium, if any) or interest on any Notes (including any Note which is required to have been purchased pursuant to an Offer to Purchase which has been made by the Company), or

(2) in respect of a covenant or provision hereof which under the Indenture cannot be modified or amended without the consent of the Holder of each outstanding Note affected, each of which, for the avoidance of doubt, shall require the consent of all the Holders of the Notes outstanding.

Satisfaction and discharge of the indenture; defeasance

The Company and the Guarantors may terminate their respective obligations under the Indenture (a "Discharge") when:

(1) either: (A) all Notes that have been authenticated and delivered have been delivered to the Trustee for cancellation, or (B) all such Notes not theretofore delivered to the Trustee for cancellation (i) have become due and payable or (ii) will become due and payable within one year or are to be called for redemption within one year under irrevocable arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Company, and the Company has irrevocably deposited or caused to be deposited with the Trustee immediately available funds or U.S. Government Obligations in an amount sufficient to pay and discharge the entire indebtedness on the Notes, not theretofore delivered to the Trustee for cancellation, for principal of, premium, if any, and interest to the Stated Maturity or date of redemption;

(2) the Company has paid or caused to be paid all other sums then due and payable under the Indenture by the Company;

(3) the deposit will not result in a breach or violation of, or constitute a default under, any other instrument to which the Company or any Guarantor is a party or by which the Company or any Guarantor is bound;

(4) the Company has delivered irrevocable instructions to the Trustee under the Indenture to apply the deposited money toward the payment of the Notes at maturity or on the redemption date, as the case may be; and

(5) the Company has delivered to the Trustee an Officer's Certificate and an opinion of counsel, each stating that all conditions precedent under the Indenture relating to the Discharge have been complied with.

The Company may elect, at its option, to have its obligations discharged with respect to the outstanding Notes ("legal defeasance"). Such defeasance means that the Company will be deemed to have paid and discharged the entire indebtedness represented by the outstanding Notes, except for:

(1) the rights of Holders of such Notes to receive payments in respect of the principal of and any premium and interest on such Notes when payments are due;

(2) the Company's obligations with respect to such Notes concerning issuing temporary Notes, registration of Notes, mutilated, destroyed, lost or stolen Notes and the maintenance of an office or agency for payment and money for security payments held in trust;

Table of Contents

(3) the rights, powers, trusts, duties and immunities of the Trustee;

(4) the Company's right of optional redemption; and

(5) the legal defeasance provisions of the Indenture.

If the Company exercises its legal defeasance option, the Subsidiary Guarantees in effect at such time will terminate.

In addition, the Company may elect, at its option, to have its obligations released with respect to certain covenants contained in the Indenture ("covenant defeasance"), including, without limitation, its obligation to make Offers to Purchase in connection with Asset Sales and any Change of Control and any omission to comply with such obligation shall not constitute a Default or an Event of Default with respect to the Notes. In the event covenant defeasance occurs, certain events (not including non-payment, bankruptcy and insolvency events) described under "Events of Default" will no longer constitute an Event of Default with respect to the Notes.

In order to exercise either legal defeasance or covenant defeasance with respect to outstanding Notes:

(1) the Company must irrevocably have deposited or caused to be deposited with the Trustee as trust funds in trust for the purpose of making the following payments, specifically pledged as security for, and dedicated solely to the benefits of the Holders of such Notes: (A) money in an amount, or (B) U.S. government obligations, which through the scheduled payment of principal and interest in respect thereof in accordance with their terms will provide, not later than the due date of any payment, money in an amount or (C) a combination thereof, in each case sufficient without reinvestment, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, to pay and discharge, and which shall be applied by the Trustee to pay and discharge, the entire indebtedness in respect of the principal of and premium, if any, and interest on such Notes on the Stated Maturity thereof or (if the Company has made irrevocable arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name and at the expense of the Company) the redemption date thereof, as the case may be, in accordance with the terms of the Indenture and such Notes;

(2) in the case of legal defeasance, the Company shall have delivered to the Trustee an opinion of counsel stating that (A) the Company has received from, or there has been published by, the Internal Revenue Service a ruling or (B) since the date of the Indenture, there has been a change in the applicable United States federal income tax law, in either case (A) or (B) to the effect that, and based thereon such opinion shall confirm that, the Holders and beneficial owners of such Notes will not recognize gain or loss for United States federal income tax purposes as a result of the deposit, defeasance and discharge to be effected with respect to such Notes and will be subject to United States federal income tax on the same amount, in the same manner and at the same times as would be the case if such deposit, defeasance and discharge were not to occur;

(3) in the case of covenant defeasance, the Company shall have delivered to the Trustee an opinion of counsel to the effect that the Holders and beneficial owners of such outstanding Notes will not recognize gain or loss for United States federal income tax purposes as a result of the deposit and covenant defeasance to be effected with respect to such Notes and will be subject to United States federal income tax on the same amount, in the same manner and at the same times as would be the case if such deposit and covenant defeasance were not to occur;

(4) no Default or Event of Default with respect to the outstanding Notes shall have occurred and be continuing at the time of such deposit after giving effect thereto (other than a Default or Event of Default resulting from the borrowing of funds to be applied to such deposit and the grant of any Lien to secure such borrowing);

Table of Contents

(5) such legal defeasance or covenant defeasance shall not cause the Trustee to have a conflicting interest within the meaning of the Trust Indenture Act (assuming all Notes are in default within the meaning of such Act);

(6) such legal defeasance or covenant defeasance shall not result in a breach or violation of, or constitute a default under, any material agreement or material instrument (other than the Indenture) to which the Company is a party or by which the Company is bound; and

(7) the Company shall have delivered to the Trustee an Officer's Certificate and an opinion of counsel, each stating that all conditions precedent with respect to such legal defeasance or covenant defeasance have been complied with.

In connection with a Discharge, in the event the Company becomes insolvent within the applicable preference period after the date of deposit, monies held for the payment of the Notes may be part of the bankruptcy estate of the Company, disbursement of such monies may be subject to the automatic stay of the bankruptcy code and monies disbursed to Holders may be subject to disgorgement in favor of the Company's estate. Similar results may apply upon the insolvency of the Company during the applicable preference period following the deposit of monies in connection with defeasance.

The Trustee

U.S. Bank National Association will act as the Trustee under the Indenture and as the initial paying agent and registrar for the Notes. The Trustee from time to time may extend credit to the Company in the normal course of business. Except during the continuance of an Event of Default, the Trustee will perform only such duties as are specifically set forth in the Indenture. During the continuance of an Event of Default that has not been cured or waived, the Trustee will exercise such of the rights and powers vested in it by the Indenture and use the same degree of care and skill in their exercise, as a prudent person would exercise or use under the circumstances in the conduct of such person's own affairs.

The Indenture and the Trust Indenture Act contain certain limitations on the rights of the Trustee, should it become a creditor of the Company, to obtain payment of claims in certain cases or to realize on certain property received in respect of any such claim as security or otherwise. The Trustee will be permitted to engage in other transactions; however, if it acquires any "conflicting interest" (as defined in the Trust Indenture Act) it must eliminate such conflict within 90 days, apply to the Commission for permission to continue or resign.

The Holders of a majority in principal amount of the outstanding Notes will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee, subject to certain exceptions. The Indenture provides that in case an Event of Default has occurred and is continuing, the Trustee shall exercise such of the rights and powers vested in it by the Indenture, and use the same degree of care and skill in their exercise, as a prudent person would exercise or use under the circumstances in the conduct of such person's own affairs. Subject to such provisions, the Trustee shall be under no obligation to exercise any of the rights or powers vested in it by the Indenture at the request or direction of any of the Holders pursuant to the Indenture, unless such Holders shall have provided to the Trustee security or indemnity reasonably satisfactory to the Trustee against the costs, expenses and liabilities which might be incurred by it in compliance with such request or direction.

No recourse may, to the full extent permitted by applicable law, be taken, directly or indirectly, with respect to the obligations of the Company or the Guarantors on the Notes or under the Indenture or any related documents, any certificate or other writing delivered in connection therewith, against (i) the Trustee in its individual capacity, or (ii) any partner, owner, beneficiary, agent, officer, director, employee, agent, successor or assign of the Trustee, each in its individual capacity, or (iii) any holder of equity in the Trustee.

Table of Contents

No personal liability of stockholders, partners, officers or directors

No director, officer, employee, stockholder, general or limited partner or incorporator, past, present or future, of the Company or any of its Subsidiaries, as such or in such capacity, shall have any personal liability for any obligations of the Company under the Notes, any Note Guarantee or the Indenture by reason of his, her or its status as such director, officer, employee, stockholder, general or limited partner or incorporator. Each Holder of Notes by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for the issuance of the Notes. Such waiver may not be effective to waive liabilities under the federal securities laws and it is the view of the Commission that such a waiver is against public policy.

Governing law

The Indenture and the Notes are governed by, and will be construed in accordance with, the laws of the State of New York.

In addition to and without limitation of the foregoing, for purposes of this definition, "Consolidated Cash Flow Available for Fixed Charges" and "Consolidated Fixed Charges" shall be calculated after giving effect, on a pro forma basis for the period of such calculation, to any Asset Sales or other dispositions or Asset Acquisitions, investments, mergers, consolidations and discontinued operations (as determined in accordance with GAAP) and designations

Furthermore, in calculating "Consolidated Fixed Charges" for purposes of determining the denominator (but not the numerator) of this "Consolidated Fixed Charge Coverage Ratio":

(ii) if interest on any Debt actually incurred on the Transaction Date may optionally be determined at an interest rate based upon a factor of a prime or similar rate, a eurocurrency interbank offered rate, or other rates, then the interest rate in effect (taking into account any Hedging Obligations applicable to such Debt) on the Transaction Date will be deemed to have been in effect during the Four Quarter Period.

Pursuant to the registration rights agreement, we have agreed to pay all expenses incident to this exchange offer (including the expenses of one counsel for the holders of the notes) and will indemnify the holders of the notes (including any broker-dealers) against certain liabilities, including liabilities under the Securities Act.

MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES

The following summary describes the material U.S. federal income tax consequences of the exchange of old notes for new notes pursuant to the exchange offer. The following discussion is based on the provisions of the U.S. Internal Revenue Code of 1986, as amended (the "Code"), and related United States Treasury regulations, administrative rulings and judicial decisions now in effect, changes to which subsequent to the date hereof may affect the tax consequences described below, possibly with retroactive effect. Some holders, including financial institutions, insurance companies, regulated investment companies, tax-exempt organizations, dealers in securities or currencies, persons whose functional currency is not the U.S. dollar or persons who hold the notes as part of a hedge, conversion transaction, straddle or other risk reduction transaction, or holders who received the old notes as compensation, or otherwise did not hold the old notes as capital assets may be subject to special rules not discussed below.

We encourage holders to consult their own tax advisors regarding the tax consequences of the exchange offer and being a holder of the new notes in light of their particular circumstances, as well as any tax consequences arising under the laws of any state, local or foreign taxing jurisdiction.

An exchange of old notes for new notes pursuant to the exchange offer will not be a taxable event for U.S. federal income tax purposes. Instead, a new note a holder receives will be treated as a continuation of such holder's investment in the corresponding old note surrendered in the exchange. Consequently, holders will not recognize any taxable gain or loss as a result of exchanging old notes for new notes pursuant to the exchange offer. The holding period of the new notes will include the holding period of the old notes, and the tax basis in the new notes will be the same as the tax basis in the old notes immediately before the exchange. The U.S. federal income tax consequences of holding and disposing of a new note will be the same as the U.S. federal income tax consequences of holding and disposing of an old note.

Exchange Offer

The exchange of the old notes for the new notes in the exchange offer should not constitute an exchange for U.S. federal income tax purposes for U.S. Holders, because the new notes should not be considered to differ materially in kind or extent from the old notes. Although the new notes do not have the right to earn additional interest enjoyed by the old notes, the deletion of such right will occur by operation of the terms of the old notes that contemplated the filing of this Registration Statement by the Company. As a result, for U.S. federal income tax purposes (i) a U.S. Holder should not recognize any income, gain or loss as a result of exchanging the old notes for the new notes; (ii) the holding period of the new notes should include the holding period of the old notes exchanged therefor; and (iii) the aggregate adjusted tax basis of the new notes should be equal to the aggregate adjusted tax basis of the old notes exchanged therefor immediately before such exchange.
