Cautionary Note Regarding Forward-Looking Statements

This report contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 relating to our future operations and prospects, including statements that are based on current projections and expectations about the markets in which we operate, and management's beliefs concerning future performance and capital requirements based upon current available information. Such statements are based on management's beliefs as well as assumptions made by and information currently available to management. When used in this document, words like "may," "might," "will," "expect," "anticipate," "plan," "believe," "potential," and similar expressions are intended to identify forward-looking statements. Actual results could differ materially from management's current expectations. For example, there can be no assurance that additional capital will not be required, and that such amounts may be material, or that additional capital, if required, will be available on reasonable terms, if at all, at such times and in such amounts as may be needed by us. In addition to these factors, among other factors that could cause actual results to differ materially, are uncertainties relating to the general economic conditions affecting our business segments; the severe disruptions to the economy, the financial markets, and the markets in which we compete; dependence of certain of our businesses on certain key customers; and the risk that we will not realize all of the anticipated benefits from efforts to optimize our asset base, as well as competitive factors relating to the aerospace industry. For a more detailed discussion of these and other factors affecting us, see the risk factors described in "Item 1A. Risk Factors."

General

Triumph Group, Inc. ("Triumph," the "Company," "we," "us," or "our") was incorporated in 1993 in Delaware. Our companies design, engineer, manufacture, repair, and overhaul a broad portfolio of aerospace and defense systems, subsystems, components, and structures. We serve the global aviation industry, including original equipment manufacturers (“OEMs”) and the full spectrum of military and commercial aircraft operators through the aircraft life cycle.

Products and Services

We offer a variety of products and services to the aerospace industry through two operating segments: (i) Triumph Systems & Support, whose companies design, develop, and support proprietary components, subsystems, and systems; produce complex assemblies using external designs; and provide full life cycle solutions for commercial, regional, and military aircraft and (ii) Triumph Interiors (formerly Aerospace Structures), whose companies, subsequent to the strategic divestitures described in Note 3 to the consolidated financial statements disclosed below, supply commercial, and regional manufacturers with aircraft interior systems, including air ducting and thermal acoustic insulation systems. We renamed this operating segment Interiors to better represent the nature of its product and service offerings subsequent to the strategic divestitures. Other than the strategic divestitures, no other change in the composition of this operating segment has occurred.

Systems & Support’s capabilities include hydraulic, mechanical, and electromechanical actuation; power and control; a complete suite of aerospace gearbox solutions, including engine accessory gearboxes and helicopter transmissions; active and passive thermal solutions technology; fuel pumps, fuel metering units, and full authority digital electronic control fuel systems; hydromechanical and electromechanical primary and secondary flight controls; and a broad spectrum of surface treatment options.

The products and capabilities within this group include the design, manufacture, build and repair of:

4

Extensive product and service offerings include full post-delivery value chain services that simplify the maintenance, repair, and overhaul ("MRO") supply chain. Through its ground support equipment maintenance, component MRO, and postproduction supply chain activities, Systems & Support is positioned to provide integrated repair solutions globally. Capabilities include metallic and composite aircraft structures; nacelles; thrust reversers; interiors; auxiliary power units; and a wide variety of pneumatic, hydraulic, fuel, and mechanical accessories. Companies in Systems & Support repair and overhaul various components for the aviation industry, including:

Interiors (formerly Aerospace Structures) products include thermo-acoustic insulation systems, environmental control system ducting, and other aircraft interior components.

Proprietary Rights

We benefit from our proprietary rights relating to designs, engineering and manufacturing processes, and repair and overhaul procedures. For some products, our unique manufacturing capabilities are required by the customer's specifications or designs, thereby necessitating reliance on us for the production of such specially designed products.

We view our name and trademark as significant to our business as a whole. Our products are protected by a portfolio of patents, trademarks, licenses, or other forms of intellectual property that expire at various dates in the future. We continually develop and acquire new intellectual property and consider all of our intellectual property to be valuable. However, based on the broad scope of our product lines, management believes that the loss or expiration of any single intellectual property right would not have a material adverse effect on our results of operations, our financial position, or our business segments. Our policy is to file applications and obtain patents for our new products as appropriate, including product modifications and improvements. While patents generally expire 20 years after the patent application filing date, new patents are issued to us on a regular basis.

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

Sales, Marketing, and Engineering

Each of our operating companies maintains responsibility for selling and marketing its specific products. These businesses are responsible for selling aerospace engineered products, integrated assemblies, cabin acoustic insulation and repair and overhaul services, reaching across our operating companies, to our OEM, military, airline, and air cargo customers. In certain limited cases, we use independent, commission-based representatives to serve our customers' changing needs in some of the markets and geographic regions in which we operate.

Triumph also maintains two account executives, for Boeing and Airbus, who coordinate corporate selling activities at these two key customers. Additionally, Triumph has established multiple Customer Focus Teams ("CFT"), which are cross functional teams focused on Triumph’s activities, performance, growth plans and coordination with large customers.

Our account executives, business development teams, and CFTs operate as the front end of the selling process, establishing or maintaining relationships, identifying opportunities to leverage our brand, and providing service for our customers. We meet our customers’ needs by designing systems that integrate the capabilities of our companies.

A significant portion of our government and defense contracts are awarded on a competitive bidding basis. We generally do not bid or act as the primary contractor but will typically bid and act as a subcontractor on contracts on a fixed-price basis. We generally sell to our other customers on a fixed price, negotiated contract, or purchase order basis.

When subcontracting, there is a risk of nonperformance by our subcontractors, which could lead to disputes regarding quality, cost or impacts to production schedules. Additionally, economic environment changes, natural disasters, trade sanctions, tariffs, budgetary constraints, earthquakes, fires, extreme weather conditions, or pandemics, affecting the prime contractor and our subcontractors may adversely affect their ability to meet or support our performance requirements, or may constrain our supply chain.

Backlog

We have a number of long-term agreements with several of our customers. These agreements generally describe the terms under which the customer may issue purchase orders to buy our products and services during the term of the agreement. These terms typically include a list of the products or repair services customers may purchase, initial pricing, anticipated quantities and, to the extent known, delivery dates. In tracking and reporting our backlog, however, we only include amounts for which we have actual purchase orders with firm delivery dates or contract requirements within the next 24 months, which primarily relate to sales to our OEM customer base. Purchase orders issued by our aftermarket customers are usually completed within a short period of time. As a result, our backlog data relates primarily to the OEM customers. The backlog information set forth below does not include the sales that we expect to generate from long-term agreements for which we do not have actual purchase orders with firm delivery dates.

As of March 31, 2023, we had outstanding purchase orders representing an aggregate invoice price of approximately$1.58 billion, of which $1.32 billion and $0.26 billion related to Systems & Support and Interiors (formerly Aerospace Structures), respectively. As of March 31, 2022, we had outstanding purchase orders representing an aggregate invoice price of approximately $1.42 billion, of which $1.17 billion and $0.25 billion related to Systems & Support and Interiors (formerly Aerospace Structures), respectively. Of the existing backlog of $1.58 billion, we estimate approximately $0.99 billion will be shipped by March 31, 2024. Refer to "Management’s Discussion and Analysis of Financial Condition and Results of Operations" for further information on our backlog.

Dependence on Significant Customers

As disclosed below in Note 18 to the consolidated financial statements, a significant portion of our net sales are to the Boeing Company (“Boeing”). Refer to Note 18 for specific disclosure of the concentration of net sales and accounts receivable to these customers. A significant reduction in sales to Boeing may have a material adverse impact on our financial position, results of operations, and cash flows.

Competition

We compete primarily with Tier 1 and Tier 2 systems suppliers and component manufacturers, some of which are divisions or subsidiaries of other large companies, in the manufacture of aircraft, systems components, and subassemblies.

Competition for the repair and overhaul of aviation components comes from four primary sources, some of whom possess greater financial and other resources than we have and, as a result, may be in a better position to handle the current environment: OEMs, major commercial airlines, government support depots, and other independent repair and overhaul companies. Some major commercial airlines continue to own and operate their own service centers, while others sell or outsource their repair and overhaul services to other aircraft operators or third parties. Large domestic and foreign airlines that provide repair and overhaul services typically provide these services not only for their own aircraft but for other airlines as well. OEMs also maintain service centers that provide repair and overhaul services for the components they manufacture. Many governments maintain aircraft support depots in their military organizations that maintain and repair the aircraft they operate. Other independent service organizations also compete for the repair and overhaul business of other users of aircraft components.

Participants in the aerospace industry compete primarily on the basis of breadth of technical capabilities, quality, delivery performance, capacity, and price.

Government Regulation, Including Environmental Regulations and Industry Oversight

Government Regulation and Industry Oversight

The aerospace industry is highly regulated in the United States by the Federal Aviation Administration ("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 and components used in specific aircraft models. If material authorizations or approvals were revoked or suspended, our operations would be adversely affected. New and more stringent government regulations may be adopted, or industry oversight heightened, in the future, and these new regulations, if enacted, or any industry oversight, if heightened, may have an adverse impact on us.

We must also satisfy the requirements of our customers, including OEMs, that are subject to FAA regulations, and provide these customers with products and repair services that comply with the government regulations applicable to aircraft components used in commercial flight operations. The FAA regulates commercial flight operations and requires that aircraft components meet its stringent standards. In addition, the FAA requires that various maintenance routines be performed on aircraft components, and we currently satisfy these maintenance standards in our repair and overhaul services. Several of our operating locations are FAA-certificated repair stations.

Generally, the FAA only grants approvals for the manufacture or repair of a specific aircraft component, rather than the broader approvals that have been granted in the past. The FAA approval process may be costly and time-consuming. In order to obtain an FAA Air Agency Certificate, an applicant must satisfy all applicable regulations of the FAA governing repair stations. These

6

regulations require that an applicant have experienced personnel, inspection systems, suitable facilities, and equipment. In addition, the applicant must demonstrate a need for the certificate. An applicant must procure manufacturer’s repair manuals from design approval holders relating to each particular aircraft component. Because of these regulatory requirements, the application process may involve substantial cost.

The certification processes for the European Aviation Safety Agency ("EASA"), which regulates this industry in the European Union; the Civil Aviation Administration of China; and other comparable foreign regulatory authorities, are similarly stringent, involving potentially lengthy audits. EASA was formed in 2002 and is handling most of the responsibilities of the national aviation authorities in Europe, such as the United Kingdom Civil Aviation Authority.

Our operations are also subject to a variety of worker and community safety laws. For example, the Occupational Safety and Health Act of 1970 ("OSHA") mandates general requirements for safe workplaces for all employees in the United States. In addition, OSHA provides special procedures and measures for the handling of hazardous and toxic substances. Specific safety standards have been promulgated for workplaces engaged in the treatment, disposal, or storage of hazardous waste. We believe that our operations are in material compliance with OSHA's health and safety requirements.

Environmental Regulation

Our business, operations, and facilities are subject to numerous stringent federal, state, local, and foreign environmental laws and regulations by government agencies, including the Environmental Protection Agency ("EPA"). Among other matters, these regulatory authorities impose requirements that regulate the emission, discharge, generation, management, transportation and disposal of hazardous materials, pollutants, and contaminants; govern public and private response actions to hazardous or regulated substances which may be or have been released to the environment; and require us to obtain and maintain licenses and permits in connection with our operations. This extensive regulatory framework imposes significant compliance burdens and risks on us. Although management believes that our operations and our facilities are in material compliance with such laws and regulations, future changes in these 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 ongoing compliance or engage in remedial actions.

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. We are frequently indemnified by prior owners or operators and/or present owners of the facilities for liabilities that we incur as a result of these investigations and the environmental contamination found that predates our acquisition of these facilities, subject to certain limitations. We also maintain a pollution liability policy that provides coverage for certain material liabilities associated with the cleanup of 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. This policy applies to all of our manufacturing and assembly operations worldwide. 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, and such obligations could be material. 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 us.

There have not been, and we do not expect there to be in the near term, material impacts on our business, financial condition or results of operations as a result of compliance with legislation or regulatory rules regarding climate change; from the known physical effects of climate change; or as a result of supporting our environmental, social, and governance ("ESG") initiatives. Increased regulation and other climate change concerns, however, could subject us to additional costs and restrictions, and we are not able to predict how such regulations or concerns would affect our business, operations or financial results.

Human Capital Resources

Our success greatly depends on identifying, attracting, engaging, developing, and retaining a highly skilled workforce in multiple areas, including engineering, manufacturing, information technology, cybersecurity, business development, finance, and strategy and management. Our human capital management strategy places significant importance on attracting and developing a talented and diverse workforce by creating a workplace that is engaging and inclusive and promotes a culture of innovation, excellence, and continuous improvement. The objectives of our human capital management strategy are aligned with and support our strategic and financial goals.

We use a wide variety of human capital measures in managing our business, including workforce demographics and diversity metrics; talent acquisition, retention, and development metrics; and employee safety and health metrics.

Diversity and Workforce Demographics

We value the diversity of our workforce and believe that the best innovation and business results are achieved when teams are populated with individuals from a diverse set of backgrounds, cultures, genders, and experiences. We have a Diversity & Inclusion Steering Committee (“DISC”) committed to creating an environment in which all employees feel valued, included, and empowered to share their unique experiences, perspectives, and viewpoints. We believe this is critical to the success of our business and the

7

delivery of world class manufacturing, engineering, and aerospace services. We track the diversity of our leadership and workforce and review our progress toward our diversity objectives with the Company’s Board of Directors on a periodic basis. Across our total employee population and based on employees who self-identify, as of March 31, 2023, approximately 28% of our global workforce are female. Of our employees based in the United States, who have self-identified, approximately 20% are multicultural and 10% are veterans.

Several of our subsidiaries are parties to collective bargaining agreements with labor unions. Under those agreements, we currently employ approximately 445 full-time employees. Currently, approximately 9% of our 4,937 permanent employees are represented by labor unions and approximately 21% of net sales are derived from the facilities at which at least some employees are unionized. Of the 445 employees represented by unions, no employees are working under contracts that have expired.

Our inability to negotiate an acceptable contract with any of our labor unions could result in strikes by the affected workers and increased operating costs as a result of higher wages or benefits paid to union members. If the unionized workers were to engage in a strike or other work stoppage, or if other employees were to become unionized, we could experience a significant disruption of our operations and higher ongoing labor costs, which could have an adverse effect on our business and results of operations.

Talent Acquisition, Retention, and Development

Hiring, developing, and retaining talented employees, particularly in highly technical areas, is an integral part of our human capital management. In addition to our focus on recruitment, we monitor attrition rates, including with respect to top talent. We believe that the commitment and connection of employees to their workplace, what we refer to as employee engagement, is a critical component of retention of top talent. We periodically conduct surveys of our workforce designed to gauge “employee engagement”. Our Employee Engagement Team monitors the responses to these surveys in our pursuit of continuously improving our employee engagement metrics. We also continue to invest in technology that supports the effectiveness, efficiency, and engagement of our employees, including advancement with our human resources information systems, communication tools and processes. These investments were particularly valuable as we navigated the challenges presented by the global COVID-19 pandemic.

We also attract and reward our employees by providing market-competitive compensation and benefit practices that cover the many facets of health, including resources and programs designed to support physical, mental, and financial wellness. We also provide tuition reimbursement and other educational and training opportunities to our employees.

Employee Safety and Health

Ensuring the safety of our employees is a top priority for us. Our safety and health program seeks to enhance business value by creating a safe and healthy work environment, promote the resiliency of our workforce and engage our employees. We provide health and safety guidance and resources to all of our businesses in order to ensure occupational safety, reduce risk, and prevent incidents. Our values include the commitment of each person to creating a safe work environment for themselves and their team members, and, through various programs and activities, we recognize individuals in our organization who make significant contributions to workplace safety.

We monitor the effectiveness of our safety and health program by comparing recordable incidents and incident severity to specific performance metrics established annually. We measure the volume of safety incidents through the total recordable incident rate (“TRIR”) metric, and we measure incident severity through the days away restricted and transferred (“DART”) metric across all of our facilities. These rates are measured on a calendar year basis, and the table below reflects our results over the three most recent calendar years:

Community Service and Philanthropy

Since 2011, we have demonstrated a deep dedication to corporate citizenship through our Wings community outreach program. Through Wings, based on the needs of their communities, our employees around the world create and implement service projects by partnering with local nonprofit organizations and engage in meaningful volunteer projects that directly benefit local charities committed to serving the needs of others. The Company enjoys partnering in local communities, and team-based volunteer events help bring our employees together as one team serving its communities. We provide our employees up to 8 hours paid vacation so that they may volunteer with charitable or community-enrichment organizations.

In 2008, the Triumph Group Charitable Foundation was formed and funded. In fiscal year of 2023, the Triumph Group Charitable Foundation allocated approximately $0.4 million to approximately 100 recipient organizations. These organizations were principally nominated by our employees. The Triumph Group Charitable Foundation makes contributions to organizations that are focused on improving our communities; supporting veterans and military families; and advancing education, particularly in the areas of science, technology, engineering, and mathematics (“STEM”).

Item 1A. Risk Factors

Strategic Risks

Strategic risk relates to our future business plans and strategies, including the risks associated with the global macro-environment; competitive threats; the demand for our products and services; the success of our investments in technology and innovation; our portfolio of businesses and capital allocation decisions; dispositions, acquisitions, joint ventures, and restructuring activity; intellectual property; and other risks.

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 results derive from commercial aviation. Our operations have been focused on designing, engineering, manufacturing, repairing and overhauling a broad portfolio of 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 such as disruption in the supply chain or high inflation 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 severe financial difficulties and requested federal assistance during the pandemic. 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; disruptions in oil production or delivery caused by hostility in oil-producing areas; or potential legislation or strategic initiatives to address climate change by reducing greenhouse gas emissions, creating carbon taxes, or implementing or otherwise participating in cap and trade programs. Airlines are sometimes unable to pass on increases in fuel prices or other costs 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, pandemics, war, terrorist attacks affecting 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-ton miles flown. Consequently, conditions or events that contribute to declines in worldwide ASMs and cargo miles flown, such as those mentioned above, could negatively impact our MRO business.

The effects of potential future public health crises, epidemics, pandemics or similar events on our business, operating results and cash flows are uncertain.

The COVID-19 pandemic had a significant negative impact on the U.S. and global economy; disrupted global supply chains; resulted in significant travel and transport restrictions, including mandated closures and orders to “shelter-in-place”; and created significant disruption of the financial markets, all of which affected the demand for our products and services. Any new pandemic or other future public health crisis, or a resurgence of COVID-19 or variants could materially impact our financial condition or results of operations.

Changes in levels of U.S. Government defense spending or overall acquisition priorities could negatively impact our financial position and results of operations.

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 (“U.S. DoD”). 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, ongoing or emerging geopolitical conflicts such as conflict between Russia and Ukraine, and the ability of the U.S. Government to enact relevant legislation such as authorization and appropriations bills. Furthermore, in 2023, Congress will again have to contend with the legal limit on U.S. debt, commonly known as the debt ceiling. The current statutory limit was reached in January 2023, requiring “extraordinary measures” to continue normally financing U.S. government obligations while avoiding breaching the debt ceiling. However, it is expected the U.S. Government will exhaust these measures by June 2023. If the debt ceiling is not raised, the U.S. Government may not be able to fulfill its funding obligations and there could be significant disruption to all discretionary programs and corresponding impacts on us and others in the industry. Accordingly, long-term uncertainty remains with respect to overall

11

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 uncertainty with respect to program-level appropriations for the 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 2023, such as the F-35, CH-47 Chinook, AH-64 Apache, KC-46A Tanker, UH-60 Black Hawk, and V-22 Osprey programs, uncertainty remains about how defense budgets in fiscal year 2024 and beyond will affect these programs. Future budget cuts 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 our 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 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 and production 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. 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.

Throughout the course of our programs, disputes with suppliers or customers could arise regarding unique contractual requirements, quality, costs or impacts to production schedules. If we are unable to successfully and equitably resolve such claims and assertions, our business, financial condition, results of operations, customer relationships and related transactions could be materially adversely affected.

In addition, negotiations over our claims may lead to disputes with our customers that would result in litigation and its associated costs and risks of damages, penalties and injunctive relief, any of which could have a material, adverse effect on our business and results of operations.

Implementing new programs and technologies subjects us to operational uncertainty.

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, subcontractor 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. 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 other fluctuations in supplier costs leading to cost overruns, if we were unable to successfully perform under revised design and manufacturing plans or successfully and equitably 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 or contract assets if they 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.

12

In order to perform on new 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.

Cancellations, reductions or delays in customer orders, or new orders under existing forward loss contracts, 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 is relatively fixed. Because several of our operating locations typically do not obtain long-term purchase orders or commitments from our customers, they must anticipate the future volume of orders based upon the historic purchasing patterns of customers and upon our discussions with customers as to their anticipated future requirements. These historic patterns may be disrupted by many factors, including changing economic conditions, inventory adjustments, or work stoppages or labor disruptions at our customers' 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. Additionally, new orders submitted under long-term contracts that have been determined to be forward loss contracts may result in significant forward loss accruals immediately upon receipt of the new order and have a material adverse effect on our business, financial condition, and results of operations.

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

As disclosed in Note 18, a significant portion of our net sales is to Boeing. As a result, a significant reduction in purchases by Boeing 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.

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 customers, which include Boeing, Airbus, Bell Helicopter, Bombardier, Cessna, General Electric, Gulfstream, Honeywell, Lockheed Martin, Northrop Grumman, Raytheon, General Electric, Rolls Royce and Sikorsky, may choose not to outsource production of systems, subsystems, components, or aerostructures due to, among other things, a desire to vertically integrate direct labor and overhead considerations, capacity utilization at their own facilities, or a 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 Parker, Eaton, Honeywell, Transdigm, and UTC Aerospace Systems. Competition for the repair and overhaul of aviation components comes from three primary sources: OEMs, major commercial airlines and other independent repair and overhaul companies.

We may need to expend significant capital to keep pace with technological or climate change related 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. For example, demand for products that are less carbon-intensive or that align with customers’ sustainability goals is expected to increase as a result of market demand, investor preferences, government legislation, and the aerospace industry’s response risks created by climate change. Failure to react timely to these trends and manage the Company’s product portfolio and innovation activities responsively could decrease the competitiveness of the Company’s products and result in the de-selection of the Company as a partner of choice. In order to keep pace with any new developments, such as sustainable energy solutions such as sustainable aviation fuels (“SAF”); hydrogen fuel; blended wing body aircraft; or other technological developments in our industry, 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. In addition, the failure to set goals, take actions, make progress and report against, commensurate with relevant market competitors, our sustainability strategy, could harm our reputation, and our ability to compete and to attract top talent or the deselection of the Company as a partner or supplier of choice.

13

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.

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 and synergies 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. In addition, if these measures are not successful or sustainable, we may be compelled or decide 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.

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

In our third party 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 could materially adversely affect our business.

Our business and results of operations could be adversely affected by disruptions in the global economy caused by Russia’s invasion of Ukraine and related sanctions and other developments.

Russia’s invasion of Ukraine and related political and economic consequences, such as sanctions and other measures imposed by the European Union, the U.S., and other countries and organizations in response, may continue to cause disruption and instability in global markets, supply chains, and industries that directly or indirectly affect the aerospace industry. As a result of this geopolitical conflict, businesses in the U.S. and globally have experienced shortages in materials and increased costs for transportation, energy, and raw materials, as well as increased risk of cyber attacks, inflationary pressures, and market volatility. The extent and duration of the war, sanctions, and resulting market disruptions are impossible to predict, and our business and results of operations could be adversely affected.

Operational Risks

Operational risk relates to risks arising from systems, processes, people, and external events that affect the operation of our businesses. It includes risks related to product and service life cycle and execution; product safety and performance; information management and data protection and security, including cybersecurity; and supply chain and business disruption.

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. Our 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. Our customers, including the U.S. Government, are increasingly requiring cybersecurity protections and mandating cybersecurity standards in our products, and we may incur additional cost to comply with such demands.

We have faced and may continue to face cybersecurity threats. These cybersecurity threats are evolving and include, but are not limited to, malicious software; ransomware; 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

14

disruptions in mission critical systems, unauthorized release of confidential or otherwise protected information and corruption of data.

Our systems are decentralized, which presents various risks, including the risk that we may be slower or less able to identify or react to problems affecting a business function than we would be in a more centralized environment. In addition, “company-wide” business initiatives, such as the integration of information technology systems, carry a higher risk of failure. Depending on the nature of the initiative, such failure could result in loss of revenues, product development delays, compromise, corruption or loss of confidential, proprietary or sensitive information (including personal information or technical business information), remediation costs, indemnity obligations and other potential liabilities, regulatory or government action, breach of contract claims, contract termination, class action or individual lawsuits from affected parties, negative media attention, reputational damage, and loss of confidence from our government clients.

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.

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

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

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, including inflationary pressures, and substantial increases in prices could increase our operating costs, which, as a result of our fixed-price contracts, we may not be able to recoup through increases in the prices of our products.

Due to economic difficulty, we may face pressure to renegotiate agreements resulting in lower margins. Our suppliers may discontinue the 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. Additionally, climate change increases the risk of potential supply chain and operational disruptions from weather events and natural disasters. The chronic physical impacts associated with climate change, for example, increased temperatures, changes in weather patterns, and rising sea levels, could significantly increase costs and expenses and create additional supply chain and operational disruption risks. 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.

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

The aerospace industry continues to experience consolidation among suppliers and customers. The 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 retaining key customers.

15

Our business could be materially adversely affected by product warranty obligations or disposition related 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. We have in the past and from time to time have ongoing dialogue with our customers regarding warranty claims. Material product warranty obligations could have a material adverse effect on our business, financial condition and results of operations.

As part of the transformation of our business over the last decade, we have engaged in a number of dispositions. Dispositions involve a number of risks and present financial, managerial and operational challenges, including diversion of management attention from running our core businesses, increased expense associated with the dispositions, potential disputes with the customers or suppliers of the disposed businesses, potential disputes with the acquirers of the disposed businesses and potential losses, write-downs or other adverse impacts on our financial statements or results of operations. As a result, we may not realize some or all of the anticipated benefits of our dispositions. For further information on commitments and contingencies, see Note 17.

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.

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

From time to time, some of our operating locations have experienced difficulties in attracting and retaining skilled personnel to design, engineer, manufacture, repair and overhaul sophisticated aircraft components, and this risk can be higher during periods of high inflation due to resulting pressure on wages. 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.

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

A significant portion of our net sales is derived from fixed-price contracts under which we have agreed to supply components systems or services 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 generally bear the majority of risk that increased or unexpected costs may reduce our profit or cause us to sustain losses on these contracts. In a fixed-price contract, we may be required to fully absorb cost overruns, notwithstanding the difficulty of estimating all of the costs we will incur in performing these contracts. This risk is greater in periods of high inflation. 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 on programs.

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 consolidated 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. Accounting for revenue recognized over time 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.

16

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 pandemic or other 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.

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.

Our unionized workforces and those of our customers and suppliers may experience work stoppages during collective bargaining agreement negotiations. 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.

Financial Risks

Financial risk relates to our ability to meet financial obligations and mitigate exposure to broad market risks, including funding and liquidity risks, such as risk related to our credit ratings and our availability and cost of funding; credit risk; inflation risk, and volatility in foreign currency exchange rates, interest rates, and commodity prices. Liquidity risk refers to the potential inability to meet contractual or contingent financial obligations (whether on- or off-balance sheet) as they arise and could potentially impact our financial condition or overall safety and soundness. Credit risk is the risk of financial loss arising from a customer or counterparty failure to meet its contractual obligations to us.

Our substantial debt could adversely affect our financial condition and our ability to operate and grow our business. The terms of our indentures governing our Senior Notes impose significant operating and financial restrictions on us and our subsidiaries, which could also adversely affect our operating flexibility and put us at a competitive disadvantage by preventing us from capitalizing on business opportunities and additional financing may not be available on terms acceptable to us.

The terms of the indentures governing our 7.750% Senior Notes due August 15, 2025 (the “2025 Notes”), and the 2028 First Lien Notes (collectively, the "Senior Notes") and the Securitization Facility impose significant operating and financial restrictions on us and require us to comply with various financial and other covenants, which, among other things, limit our ability to incur additional indebtedness, create liens, dispose of assets, and enter into certain transactions. We are in compliance with all of our debt covenants.

We cannot assure you that we will be able to remain in compliance with such covenants in the future or, if we fail to do so, that we will be able to obtain waivers from the applicable holders of such indebtedness or amend such covenants and other terms of the agreements governing such indebtedness on commercially reasonable terms, if at all. Failure to comply with such covenants will entitle the applicable holders of such indebtedness to exercise remedies, including to require immediate repayment of outstanding amounts and to terminate commitments under such indebtedness, which could have a material adverse effect on our business, operations, and financial condition.

We may need to obtain additional financing in order to meet our debt obligations as they come due, to support our operations and/or to make acquisitions. Our access to the debt capital markets and the cost of borrowings are affected by a number of factors, including market conditions and the strength of our credit ratings. If we cannot obtain adequate sources of credit on favorable terms, or at all, our business, operations, and financial condition could be adversely affected. We may also seek transactions to extend the maturity of our debt, reduce leverage or obtain covenant flexibility. Such transactions could result in us incurring additional secured debt or issuing additional equity, which could increase the risks described above.

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.

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

17

customers' need for and ability to purchase our products or services may decrease, and our suppliers may increase their prices, reduce their output or change their terms of sale. If our customers' or suppliers' operating and financial performance deteriorates, or if they are unable to make scheduled payments or obtain credit, our customers may not be able to pay, or may delay payment of, accounts receivable owed to us, and our suppliers may restrict credit or impose different payment terms. Any inability of customers to pay us for our products and services or any demands by suppliers for different payment terms may adversely affect our earnings and cash flow.

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

As we pursue customers in Asia, South America and other less developed aerospace markets throughout the world, our inability to ensure the creditworthiness of our customers in these areas could adversely impact our overall profitability. In addition, with operations in China, France, Germany, Mexico, Thailand and the United Kingdom, and customers throughout the world, we are 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:

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 overfunded or underfunded 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 underfunded status of the plans recorded on our consolidated balance sheets and result in additional cash funding requirements to meet the minimum required funding levels.

Prolonged periods of inflation where we do not have adequate inflation protections in our customer contracts could have a material adverse effect on our results of operations.

A majority of our sales are conducted pursuant to medium- or long-term contracts that set fixed unit prices. Certain, but not all, of these contracts provide for price adjustments for index-based inflation or adjustments related to updated or final product cost for certain components. Ongoing inflationary pressures have caused and may continue to cause certain of our material and labor costs to increase, which can adversely affect our profitability and cash flows, particularly when we are unable to increase customer contract values or pricing to offset those pressures. Although we have attempted to minimize the effect of inflation on our business through contractual protections, our contracts that are medium- to long-term fixed price contracts increase our exposure to sustained or higher than anticipated increases in costs of labor or material. Prolonged global inflationary pressures

18

have also impacted energy, freight, raw material, interest rates, labor, and other costs, and we may experience reduced levels of profitability as a result of ongoing inflationary pressures.

Legal & Compliance Risks

Legal and compliance risk relates to risks arising from the government and regulatory environment and action and from legal proceedings and compliance with integrity policies and procedures, including those relating to financial reporting and environmental, health, and safety matters. Government and regulatory risk includes the risk that the government or regulatory actions will impose additional cost on us or require us to make adverse changes to our business models or practices.

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.

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.

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. Innocent Landowner Regulations require an Environmental Site Assessment prior to acquisition to prevent unknowingly acquiring impaired property. Once identified, if the transaction continues, the impairment is not covered by insurance. 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. Lawsuits, claims and costs involving environmental matters may 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 that we incur as a result of these investigations and the

19

environmental contamination found that predates our acquisition of these facilities, subject to certain limitations, including, but not limited to, specified exclusions, deductibles and limitations on the survival period of the indemnity. We also maintain a pollution liability policy that provides coverage, subject to specified limitations, for specified material liabilities associated with the cleanup 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 us to damages and potential injunctive relief, which, if granted, may preclude us 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.

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.

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.

20

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.

U.S. DoD facility security clearance is required in order to be awarded and be able to perform on classified contracts for the U.S. 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 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.

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 is 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, environmental protection, climate change, as well as accounting standards and taxation requirements (including tax-rate changes, new tax laws or revised tax law interpretations).

Item 1B. Unresolved Staff Comments

None.

Item 2. Properties

As of March 31, 2023, we conducted business from office and operating facilities throughout the United States and select global markets, with our largest international facilities being located in the United Kingdom, Mexico, and Thailand. We also lease a facility in Berwyn, Pennsylvania, for our corporate headquarters. In May 2023, our corporate headquarters were relocated to Radnor, Pennsylvania.

We believe that our properties have been adequately maintained, are in good operating condition, and are suitable to support our operations for the foreseeable future.

Item 3. Legal Proceedings

In the ordinary course of business, we are involved in disputes, claims and lawsuits with employees, suppliers and customers, as well as governmental and regulatory inquiries, that are deemed to be immaterial. Some may involve claims or potential claims of substantial damages, fines, penalties or injunctive relief regarding unique contractual requirements, quality, costs, or impacts to production schedules. In addition, in connection with certain divestitures made by the Company, we have received claims relating to closing working capital adjustments to purchase prices as well as claims regarding alleged violations of contractual terms, representations, and warranties of the sale agreements and demands for honoring guarantee or indemnification obligations. While we cannot predict the outcome of any pending or future litigation. proceeding or claim and no assurances can be given, we intend to vigorously defend claims brought against the Company and do not believe that any pending matter will have a material effect, individually or in the aggregate, on our financial position or results of operations. If we are unable to successfully and equitably resolve such claims and assertions, our business, financial condition, and results of operations could be materially adversely affected.

Item 4. Mine Safety Disclosures

Not applicable.

PART II

Item 5. Market for Registrant's Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities

Our common stock is traded on the New York Stock Exchange under the symbol "TGI." As of May 10, 2023, there were approximately 118 holders of record of our common stock and we believe that our common stock was beneficially owned by approximately 17,306 persons.

Dividend Policy

During fiscal 2023 and 2022, we made no declaration or payments of dividends due to the March 2020 suspension of our dividend program. This suspension is still in place. Our declaration and payment of cash dividends in the future and the amount thereof will depend upon our results of operations, financial condition, cash requirements, future prospects, limitations imposed by credit agreements or indentures governing debt securities and other factors deemed relevant by our Board of Directors. No assurance can be given that cash dividends will be declared and paid at historical levels or at all. Certain of our debt arrangements restrict our paying dividends and making distributions on our capital stock, except for the payment of stock dividends and redemptions of an employee's shares of capital stock upon termination of employment. We currently have an accumulated deficit which could limit or restrict our ability to pay dividends in the future.

Repurchases of Stock

Information about our repurchases during the three months ended March 31, 2023, of our common stock that is registered pursuant to Section 12 of the Exchange Act is disclosed in the table below.

(1) Represents shares surrendered to the Company due to restricted share forfeitures or to satisfy tax withholding obligations in connection with employees’ share-based compensation awards.

(2) Excludes shares acquired at no cost as a result of restricted share forfeitures.

We currently have an accumulated deficit which, together with certain restrictive covenants imposed by credit agreements or indentures governing debt securities, could limit or restrict our ability to repurchase stock in the future.

Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations

The following discussion should be read in conjunction with the consolidated financial statements and notes thereto contained elsewhere herein.

OVERVIEW

Business

We are a major supplier to the aerospace industry across commercial and military end markets and have two reportable segments: (i) Systems & Support, whose companies’ revenues are primarily derived from integrated solutions, including design, development, and support of proprietary components, subsystems, and systems; production of complex assemblies using external designs; and full life cycle solutions for commercial, regional, and military aircraft; and (ii) Interiors (formerly Aerospace Structures), whose companies' revenues are primarily derived from supplying commercial and regional manufacturers with thermo-acoustic insulation, composite components, ducting and primarily to customer designs and model-based definition.

Divestitures

In July 2022, we completed the sale of our manufacturing operations located in Stuart, Florida, and recognized a gain of approximately $96.8 million in the year ended March 31, 2023. The Stuart operations specialized in the assembly of large, complex metallic structures such as wing and fuselage assemblies. As a result of the completion of this sale, we have exited our structures business and reshaped our portfolio of companies to consist primarily of businesses providing systems and aftermarket services. The operating results associated with the Stuart operations are included within Interiors (formerly Aerospace Structures) through the date of divestiture.

Summary of Significant Financial Results

Significant financial results for the fiscal year ended March 31, 2023, include:

Aviation Manufacturing Jobs Protection Program

As disclosed in Note 2, in November 2021, the Company entered into an agreement with the Department of Transportation (“DOT”) under the Aviation Manufacturing Jobs Protection Program (“AMJP”). We received total proceeds under this program of $19.4 million, of which approximately $8.8 million was received during the three months ended June 30, 2022. In July 2022, we received a letter from the DOT confirming that we had satisfied the reporting requirements under the AMJP. In the years ended March 31, 2023 and 2022, approximately $5.3 million and $14.1 million, respectively, of the grant benefit has been recognized as a reduction in cost of sales.

Warrants Distribution

As disclosed in Note 2, on December 19, 2022, we issued approximately 19.5 million Warrants to holders of record of common stock as of the close of business on December 12, 2022. Each Warrant represents the right to purchase initially one share of common stock at an exercise price of $12.35 per Warrant. Payment for shares of common stock on exercise of Warrants may be in (i) cash or (ii) under certain circumstances, Designated Notes (as defined in Note 2). Assuming that all Warrants distributed are fully exercised for cash (including over-exercise options), we would receive proceeds of approximately $270.0 million in the aggregate, net of transaction costs. We intend to use any cash proceeds for general corporate purpose, which may include the repayment of debt. Any Designated Notes received upon exercise of a Warrant are expected to be retired and cancelled by the Company. If holders exercise Warrants through the surrender of Designated Notes, the amount of the Company's outstanding debt will be reduced. Following the issuance on December 19, 2022 through March 31, 2023, approximately 0.4 million Warrants have been exercised.

Significant Developments in Key Programs

Discussion of significant developments on key programs is included below.

Boeing 737

The Boeing 737 program represented approximately 11% and 5% of revenue for the fiscal years ended March 31, 2023 and 2022, respectively, inclusive of both OEM production and aftermarket sales. Passenger flights on the 737 MAX program recently resumed in China, which is a key market for this platform. Despite near-term headwinds on this program as publicly disclosed by Boeing, they also disclosed that they plan to increase production on this platform from 31 per month to 38 per month later in calendar 2023.

24

Boeing 767

Boeing's 767 program includes the commercial program and a derivative to support the related tanker program. The 767 currently has a production rate of three aircraft per month. Approximately 3% of our revenue in the year ended March 31, 2023, was generated by 767 production from our Stuart, Florida, operations, which, as disclosed above, was sold as of July 1, 2022. The impact of 767 production on our operating income was not significant.

Although none of the programs noted above individually are expected to have a material impact on our net revenues, they do have the potential, either individually or in the aggregate, to materially and negatively impact our consolidated results of operations if future changes in estimates result in the need for a forward loss provision. Absent any such loss provisions, we do not anticipate that any of these programs will significantly dilute our future consolidated margins.

In the years ended March 31, 2022 and 2021, we completed several strategic divestitures. Refer to Note 3 for further discussion of these transactions.

RESULTS OF OPERATIONS

The following includes a discussion of our consolidated and business segment results of operations for the year ended March 31, 2023, compared with the year ended March 31, 2022. Our diverse structure and customer base do not allow for precise comparisons between periods of the impact of price and volume changes to specific line items in our results of operations. However, we have disclosed the significant variances between the respective periods. A discussion of our consolidated and business segment results of operations for the year ended March 31, 2022, compared with the year ended March 31, 2021, can be found under Item 7 in our Annual Report on Form 10-K for the fiscal year ended March 31, 2022, filed with the Securities and Exchange Commission (the "SEC") on May 23, 2022, and is incorporated by reference.

Non-GAAP Financial Measures

We prepare and publicly release annual audited and quarterly unaudited financial statements prepared in accordance with U.S. GAAP. In accordance with Securities and Exchange Commission (the "SEC") rules, we also disclose and discuss certain non-GAAP financial measures in our public filings and earning releases. Currently, the non-GAAP financial measures that we disclose are Adjusted EBITDA, which is our net income (loss) before interest and gains or losses on debt extinguishment, income taxes, amortization of acquired contract liabilities, consideration payable to customer related to divestitures, legal judgments and settlements, gains/loss on divestitures, gains/losses on warrant remeasurements and warrant-related transaction costs, share-based compensation expense, depreciation and amortization (including impairment of long-lived assets), other non-recurring impairments, and the effects of certain pension charges such as curtailments, settlements, withdrawals, and other early retirement incentives; and Adjusted EBITDAP, which is Adjusted EBITDA, before pension expense or benefit (excluding pension charges already adjusted in Adjusted EBITDA). We disclose Adjusted EBITDA on a consolidated and Adjusted EBITDAP 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 with our previously reported results of operations.

We view Adjusted EBITDA and Adjusted EBITDAP as operating performance measures and, as such, we believe that the U.S. GAAP financial measure most directly comparable to such measures is net income (loss). In calculating Adjusted EBITDA and Adjusted EBITDAP, we exclude from net income (loss) 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 and Adjusted EBITDAP are not measurements of financial performance under U.S. GAAP and should not be considered as a measure of liquidity, as an alternative to net income (loss), 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 or Adjusted EBITDAP as a substitute for any U.S. GAAP financial measure, including net income (loss). In addition, we urge investors and potential investors in our securities to carefully review the reconciliation of Adjusted EBITDA and Adjusted EBITDAP to net income (loss) set forth below, 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 U.S. GAAP financial information with our Adjusted EBITDA and Adjusted EBITDAP.

Adjusted EBITDA and Adjusted EBITDAP are 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 (loss) has included significant charges for depreciation and amortization.

25

Adjusted EBITDA and Adjusted EBITDAP exclude these charges and provide meaningful information about the operating performance of our business, apart from charges for depreciation and amortization. We believe the disclosure of Adjusted EBITDA and Adjusted EBITDAP helps investors meaningfully evaluate and compare our performance from quarter to quarter and from year to year. We also believe Adjusted EBITDA and Adjusted EBITDAP are measures of our ongoing operating performance because the isolation of noncash charges, such as depreciation and amortization, and nonoperating items, such as interest, income taxes, pension and other postretirement benefits, 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 and Adjusted EBITDAP to provide financial measures by which to compare our operating performance against that of other companies in our industry.

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

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