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:

Aircraft and engine-mounted accessory drives	Thermal control systems and components
Cargo hooks	High lift actuation
Cockpit control levers	Hydraulic systems and components
Control system valve bodies	Landing gear actuation systems
Electronic engine controls	Landing gear components and assemblies
Exhaust nozzles and ducting	Main engine gear box assemblies
Geared transmissions and drive train components	Main fuel pumps
Fuel-metering units	Secondary flight control systems
Vibration absorbers

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:

Air cycle machines	Blades and vanes
APUs	Cabin panes, shades, light lenses and other components
Constant speed drives	Combustors
Engine and airframe accessories	Stators
Flight control surfaces	Transition ducts
Integrated drive generators	Sidewalls
Nacelles	Light assemblies
Remote sensors	Overhead bins
Thrust reversers	Fuel bladder cells

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:

	Calendar year ended
Safety Metric	2022		2021		2020
TRIR		1.2		1.8		1.9
DART		0.5		1.0		1.3
TRIR = total number of recordable cases x 200,000 / total hours worked
DART = number of cases with days away from work x 200,000 / total hours worked by all employees

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:

•availability of capital to our suppliers;

•workforce shortages at our suppliers;

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

•a work stoppage or strike by our suppliers' employees;

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

•the failure of essential equipment at our suppliers' plants;

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

•contractual amendments and disputes with our suppliers;

•reduction to credit terms; and

•geopolitical conditions in the global supply base.

In addition, some contracts with our suppliers for raw materials, component parts and other goods are short-term contracts, which are subject to termination on a relatively short-term basis. The prices of our raw materials and component parts fluctuate depending on market conditions, 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:

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

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

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

•inability to obtain, maintain or enforce intellectual property rights;

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

•unexpected adverse changes in the laws or regulatory requirements outside the United States, including those with respect to environmental protection, disclosure of social and environmental risks, opportunities, and impact, export duties and quotas;

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

•difficulty with staffing and managing widespread operations; and

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

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.

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:

•Net sales decreased 5.5% to $1.38 billion.

•Operating income was $238.1 million.

•Net income was $89.6 million or $1.20 per diluted common share.

•Backlog increased 11.3% over the prior year to $1.58 billion.

•We used $52.3 million of cash flows in operating activities.

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:

•Gains or losses from sale of assets and businesses may be useful for investors to consider because they reflect gains or losses from sale of operating units or other assets. We do not believe these earnings necessarily reflect the current and ongoing cash earnings related to our operations.

•Warrants remeasurement gains or losses and warrant-related transaction costs may be useful for investors to consider because they reflect the mark-to-market changes in the fair value of our warrants and the costs associated with warrants issuance or settlement. We do not believe these earnings necessarily reflect the current and ongoing cash earnings related to our operations.

•Consideration payable to a customer related to a divestiture may be useful for investors to consider because it reflects consideration paid to facilitate the ultimate sale of operating units. We do not believe these charges necessarily reflect the current and ongoing cash earnings related to our operations.

•Legal judgments and settlements, when applicable, may be useful for investors to consider because it reflects gains or losses from disputes with third parties. We do not believe these earnings necessarily reflect the current and ongoing cash earnings related to our operations.

•Non-service defined benefit income or expense from our pension and other postretirement benefit plans (inclusive of certain pension related transactions such as curtailments, settlements, withdrawals, and early retirement or other incentives) may be useful for investors to consider because they represent the cost of postretirement benefits to plan participants, net of the assumption of returns on the plan's assets and are not indicative of the cash paid for such benefits. We do not believe these earnings necessarily reflect the current and ongoing cash earnings related to our operations.

•Amortization of acquired contract liabilities may be useful for investors to consider because it represents the noncash earnings on the fair value of off-market contracts acquired through acquisitions. We do not believe these earnings necessarily reflect the current and ongoing cash earnings related to our operations.

•Amortization expense and nonrecurring asset impairments (including goodwill, intangible asset impairments, and nonrecurring rotable inventory impairments) may be useful for investors to consider because it represents the estimated attrition of our acquired customer base and the diminishing value of trade names, product rights, licenses, or, in the case of goodwill, other assets that are not individually identified and separately recognized under U.S. GAAP, or, in the case of nonrecurring asset impairments, the impact of unusual and nonrecurring events affecting the estimated recoverability of existing assets. We do not believe these charges necessarily reflect the current and ongoing cash charges related to our operating cost structure.

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

•Share-based compensation may be useful for investors to consider because it represents a portion of the total compensation to management and the board of directors. We do not believe these charges necessarily reflect the current and ongoing cash charges related to our operating cost structure.

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

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

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.

The fluctuations from period to period within the amounts of the components of the reconciliations above are discussed further below within Results of Operations.

Fiscal year ended March 31, 2023, compared with fiscal year ended March 31, 2022

	Year Ended March 31,

Commercial OEM sales decreased $102.4 million, or 15.9% due to divestitures and exited or sunsetting programs, which represented approximately $206.9 million in net changes. Excluding impacts from divestitures and exited or sunsetting programs, organic Commercial OEM sales increased $104.5 million, or 28.7% with over half the improvement driven by increased production volumes on the Boeing 737 program, as well as on increases across other commercial fixed wing and rotorcraft programs and an intellectual property transaction.

Military OEM sales decreased $31.3 million, or 10.7% primarily due to divestitures, as well as lower sales related to the E2-D and AH-64 programs, partially offset by increased sales related to the CH-53K and CH-47 programs.

Aftermarket sales include both repair and overhaul services as well as the sales of spare parts. Commercial Aftermarket sales increased $80.6 million, or 32.9%. Excluding impacts from divestitures, organic Commercial Aftermarket sales increased $86.9 million, or 36.8%, driven by the continued pandemic recovery, including improvement in overall air travel metrics, with the primary increase on 737 volumes.

Military aftermarket sales decreased $11.5 million, or 5.1% driven by reduced repairs and spares across several rotorcraft platforms relative to the prior year.

Segment Operating Income

Segment operating income increased $24.5 million, or 13.8%. Excluding impacts from divestitures and exited or sunsetting programs, organic segment operating income increased $44.6 million, or 30.9%, driven by the improved gross margin noted below along with reduced general and administrative human capital costs $5.3 million, lower depreciation and amortization $6.4 million, partially offset by increased travel and meeting costs $2.0 million and higher professional services costs $1.6 million.

Cost of OEM Sales decreased primarily due to divestitures and exited or sunsetting programs, which represented approximately $209.8 million in net changes, partially offset by $24.9 million in reductions in acquired contract reserves recognized in the prior year period.

Cost of Aftermarket sales increased primarily due to the increased Commercial Aftermarket sales noted above. Aftermarket gross profit margin increased in the fiscal year ended March 31, 2023 from the fiscal year ended March 31, 2022. This increase was driven by increased volumes and related efficiencies, as well as increases in prices for repair and overhaul services.

28

Consolidated gross profit margin improved to 28.1% for the fiscal year ended March 31, 2023, from 26.5% for the fiscal year ended March 31, 2022. This improvement was driven by the increased mix in Aftermarket sales as a percentage of total sales.

Excluding impacts from divestitures and exited or sunsetting programs, organic gross margin for the year ended March 31, 2023, was 28.1% compared with 28.5% for the year ended March 31, 2022. The gross margin for the year ended March 31, 2023, decreased primarily as a result of the prior year reductions in acquired contract reserves recognized in the prior year partially offset by the increase in mix in Aftermarket sales as a percentage of total sales.

Corporate Income (Expense)

Corporate income (expense) includes gain on sale of assets and businesses of $101.5 million for fiscal 2023 compared to loss on sale of assets and businesses of $9.3 million for fiscal 2022. Excluding the impact of gains and losses on sales of assets and businesses, corporate expenses increased $1.5 million.

Interest Expense and Other

Interest expense and other increased due to unfavorable changes in foreign currency exchange rates of approximately $6.6 million offset by lower interest on lower relative debt balances compared to the prior year period.

We recognized debt extinguishment losses of $33.0 million for fiscal year ended March 31, 2023, compared with $11.6 million for fiscal year ended March 31, 2022. In March 2023, we issued $1.20 billion aggregate principal amount of the 2028 First Lien Notes and redeemed the 2024 First Lien Notes ($543.8 million aggregate principal amount) and the 2024 Second Lien Notes ($525.0 million aggregate principal amount) resulting in prepayment premiums and write off of prior deferred financing cost of $31.6 million in the aggregate. The remaining debt extinguishment losses in fiscal 2023 and fiscal 2022 were related to mandatory redemptions under our 2024 First Lien Notes related to proceeds from prior asset sales.

Non-service Defined Benefit Income

Non-service defined benefit income increased by $14.3 million, to $19.7 million for the fiscal year ended March 31, 2023, compared with $5.4 million for the fiscal year ended March 31, 2022. The increase was primarily due to the recognition of curtailment and settlement losses of approximately $52.0 million in the aggregate upon the completion of the composites and large structure manufacturing divestitures, the settlement of a legacy fully-funded pension obligation, and the settlement of pension obligations of certain retired participants in our qualified U.S. pension plan all in the fiscal year ended March 31, 2022, partially offset by approximately $14.6 million of pension cost recognized in the fiscal year ended March 31, 2023, as a result of our withdrawal from a multiemployer pension plan.

Income Taxes

The income tax expense was $6.1 million for the fiscal year ended March 31, 2023, reflecting an effective tax rate of 6.4%. During the fiscal year ended March 31, 2023, we adjusted the valuation allowance against the consolidated net deferred tax asset by $0.2 million primarily due to a utilization of net operating loss carryforward, utilization of capital loss carryforward, and changes to temporary differences related to interest disallowance, amortization of research and development costs, and pension and other postretirement benefit plans. As of March 31, 2023, management determined that it was necessary to maintain a valuation allowance against principally all of our net deferred tax assets.

Business Segment Performance

We report our financial performance based on the following two reportable segments: Systems & Support and Interiors (formerly Aerospace Structures). Our Chief Operating Decision Maker ("CODM") utilizes Adjusted EBITDAP as a primary measure of profitability to evaluate the performance of our segments and allocate resources.

The results of operations among our reportable segments vary due to differences in competitors, customers, extent of proprietary deliverables and performance. For example, Systems & Support, which generally includes proprietary products and/or arrangements where we become the primary source or one of a few primary sources to our customers, our unique manufacturing capabilities command a higher margin.

Refer to Item 1 for further details regarding the operations and capabilities of each of our reportable segments.

29

We currently generate a majority of our revenue from sales to OEMs and aftermarket MRO services in the commercial airline and military and defense markets. Our growth and financial results are largely dependent on continued demand for our products and services within these markets. If any of the related industries experiences a downturn, our clients in these sectors may conduct less business with us. The loss of one or more of our major customers or an economic downturn in the commercial airline or the military and defense markets could have a material adverse effect on our business.

Net Sales

Excluding impacts from divestitures, organic net sales, adjusted for intersegment sales, increased by $148.8 million, or 14.6%, primarily as a result of the continued recovery from the pandemic driving volume for both commercial OEM and aftermarket sales, as noted above. Net sales included approximately $16.3 million recognized as a result of a intellectual property transaction in the fiscal year ended March 31, 2023, compared to approximately $4.0 million as a result of a prior period intellectual property transaction. The prior year period included $11.7 million in sales from our since divested operations in Staverton, United Kingdom.

Operating Income and Adjusted EBITDAP

Excluding impacts from divestitures, organic operating income increased by $26.9 million, or 16.4%., and organic gross margin for the year ended March 31, 2023, was 30.4% compared with 32.0% for the year ended March 31, 2022. Organic gross margin for the year ended March 31, 2023 included the recognition of grant benefits under the AMJP agreement with the DOT of approximately $5.3 million, compared to $14.0 million of associated benefits in the year ended March 31, 2022. Additionally, approximately $24.9 million in reductions in acquired contract reserves recognized in the prior year period were partially offset by the current year intellectual property transaction margin benefits. The increase in organic operating income and Adjusted EBITDAP is the result of the increased volume described above and the effects of these changes in gross margin, with additional improvement resulting from approximately $5.2 million in decreased administrative human capital related costs.

Operating Margin and Adjusted EBITDAP Margin

Systems & Support operating income and Adjusted EBITDAP as a percentage of segment sales both increased due to the factors described above.

Interiors (formerly Aerospace Structures):

Net Sales

30

Excluding impacts from divestitures and exited or sunsetting programs, which resulted in $226.2 million in decreased sales, organic net sales increased by $8.3 million, or 6.7%. Organic net sales increased primarily due to increased commercial OEM volume on the 737 program, partially offset by decreased volume on certain commercial widebody programs.

Operating Income and Adjusted EBITDAP

Excluding impacts from divestitures and exited or sunsetting programs, organic operating income increased by $6.4 million. This improvement was partially offset by declines from the divestitures and sunsetting programs of $9.3 million, including the impact of the consideration payable to a customer related to the divestiture. Excluding the impacts from divestitures and exited or sunsetting programs, organic gross margin for the year ended March 31, 2023, was 7.8% compared with 0.4% for the year ended March 31, 2022. The organic gross margin for the year ended March 31, 2023, increased primarily due to increased commercial OEM production volumes and related overhead absorption benefits.

Operating Margin and Adjusted EBITDAP Margin

Interiors (formerly Aerospace Structures) operating income and Adjusted EBITDAP as a percentage of segment sales both increased due to the increase in operating income as noted above, except for the impact of the consideration payable to a customer related to the divestiture, which is excluded from Adjusted EBITDAP.

Liquidity and Capital Resources

Operating Cash flows

Our working capital needs are generally funded through our current cash and cash equivalents, cash flows from operations, and proceeds from the Securitization Facility. For the fiscal year ended March 31, 2023, we had a net cash outflow of $52.3 million from operating activities, compared with a net cash outflow of $137.0 million for the fiscal year ended March 31, 2022, an improvement of $84.8 million. Cash flows included increased inventory and accounts receivable levels on the ramping organic growth. Reflecting the change in our portfolio of businesses that is a result of our strategic divestitures, working capital stability has improved in the twelve months ended March 31, 2023, compared with the twelve months ended March 31, 2022. Interest payments were approximately $138.5 million for the twelve months ended March 31, 2023, as compared with approximately $137.9 million for the twelve months ended March 31, 2022, with the increase principally driven by the acceleration of certain interest payments made upon redemption of the 2024 First Lien Notes.

As disclosed in Note 2 in November 2021 the Company entered into an agreement with the DOT under the AMJP. We received total proceeds under this program of $19.4 million, of which approximately $8.8 million was received in the three months ended June 30, 2022, compared to $10.6 million received in the year ended March 31, 2022. These cash receipts are classified within cash from operations. Refer to Note 2 for further discussion.

Investing Cash Flows

Cash flows used in investing activities for the fiscal year ended March 31, 2023, increased $208.4 million from the cash flows provided by investing activities for the fiscal year ended March 31, 2022. Cash flows used in investing activities for the fiscal year ended March 31, 2023, consisted payments related to the sale of assets and businesses, including working capital settlements, of $6.2 million. We also used approximately $20.7 million for capital expenditures. Cash flows used in investing activities for the fiscal year ended March 31, 2022, included cash from the sale of assets and businesses of approximately $224.5 million offset by capital expenditures of $19.7 million and the purchase of a facility related to divested businesses of approximately $21.6 million. We currently expect capital expenditures in fiscal 2024 to be in the range of $25.0 - $30.0 million. The majority of our planned fiscal 2024 capital expenditures are capital investments designed to improve our manufacturing efficiency and expand our capabilities.

Financing Cash Flows

Cash flows provided by financing activities for the fiscal year ended March 31, 2023, were $65.8 million, compared with cash flows used in financing activities for the fiscal year ended March 31, 2022, of $392.7 million. In the year ended March 31, 2023, the following significant financing cash flow events occurred:

•We completed the offering of $1.20 billion aggregate principal amount of the 9.000% senior secured 2028 First Lien Notes, paying approximately $17.1 million in debt issuance costs.

•We used net proceeds of $1.13 billion from the 2028 First Lien Notes to (i) redeem in full all of the 2024 First Lien Notes, (ii) to acquire a portion of our existing 2024 Second Lien Notes that we had offered to purchase as part of the Tender Offer, and (iii) to redeem the balance of the 2024 Second Lien Notes that were not tendered in the Tender Offer, (iv) to pay off existing borrowings, without a reduction in commitment, under the Securitization Facility and (v) increase our available cash for general corporate purposes. We paid approximately $26.2 million in redemption premiums. Refer to Note 10 for further disclosure related to our long-term debt.

•We issued approximately 19.5 million Warrants (as defined in Note 2) to holders of record of common stock as of the close of business on December 12, 2022. Following the issuance on December 19, 2022, through March 31, 2023, approximately 0.4 million Warrants have been exercised, resulting in approximately $4.1 million in cash proceeds, net of related transaction costs. Refer to Note 2 for further disclosure related to the Warrants.

31

The remainder of financing cash flows pertains primarily to borrowings and payments under finance leases and the repurchase of common stock to satisfy employee tax withholding obligations resulting from equity compensation. As of March 31, 2023, we had $227.4 million of cash on hand and approximately $59.8 million was available under the Securitization Facility after giving effect to approximately $19.8 million in outstanding letters of credit, all of which were accruing interest at 0.125% per annum.

As disclosed in Note 17, in April 2023, we were notified that our exit from the composites manufacturing operations in Spokane, Washington resulted in a multiemployer pension plan withdrawal obligation of approximately $14.6 million, which is expected to be satisfied through annual payments over a period of at least ten years.

We currently expect fiscal 2024 operations to result in net cash inflows, however, due to cyclicality we anticipate using cash over the first half of fiscal 2024 and generating in the second half. We believe, based on an assessment of our current cash holdings as presented on the accompanying consolidated balance sheet as of March 31, 2023, as well as current market conditions, that cash flows from operations and borrowings under the Securitization Facility will be sufficient to meet anticipated cash requirements for our current operations for at least the next 12 months. We also believe, based on our current cash, our fiscal 2024 operating cash flow expectations, and the expected expansion of cash flows from operations subsequent to fiscal 2024, that we have the ability to generate and obtain adequate amounts of cash to meet anticipated cash requirements for the foreseeable future. We continually evaluate opportunities to access the credit and capital markets. We may also seek transactions to extend the maturity of our indebtedness, reduce leverage, or decrease interest expense. Such transactions could include one or more repurchases or exchanges of our outstanding indebtedness. These transactions could increase our total amount of secured indebtedness or be dilutive to stockholders. There can be no assurances if or when we will consummate any such transactions or the timing thereof.

The Senior Notes are our senior obligations and rank equally in right of payment with all of our other existing and future senior indebtedness and senior in right of payment to all of our existing and future subordinated indebtedness.

The 2028 First Lien Notes are (a) effectively senior to all existing and future second lien obligations and all existing and future unsecured indebtedness of the Company and the Guarantor Subsidiaries, but only to the extent of the value of the Collateral (as defined below), and after giving effect to any permitted additional first lien secured obligations and other permitted liens of senior or equal priority; (b) secured by the Collateral on a pari passu basis with any future permitted additional first lien secured obligations, subject to a Collateral Trust Agreement (as defined below); (c) effectively subordinated to any existing and future obligations of the Company and the Guarantor Subsidiaries that are secured by assets that do not constitute the Collateral, in each case, to the extent of the value of the assets securing such obligations; and (d) structurally subordinated to all existing and future indebtedness and other liabilities of the Company’s existing and future subsidiaries that do not guarantee the First Lien Notes, including the Securitization Facility.

The 2025 Notes are effectively subordinated to all obligations of the Company and the Guarantor Subsidiaries that are (A) secured by a lien on the Collateral (including the 2028 First Lien Notes) and certain cash management and hedging obligations, or (B) secured by assets that do not constitute the Collateral, in each case to the extent of the value of the assets securing such obligations.

The Senior Notes are guaranteed on a full, senior, joint and several basis certain of the Company’s domestic restricted subsidiaries (the “Guarantor Subsidiaries”). Currently, our only consolidated subsidiaries that are not guarantors of the Senior Notes (the "Non-Guarantor Subsidiaries") are: (i) the receivables securitization special purpose entity, and (ii) charitable foundation entity. The 2028 First Lien Notes and the related guarantees are secured by first-priority liens on substantially all of our assets and our subsidiary guarantors, whether now owned or hereafter acquired (the “Collateral”).

Pursuant to the documentation governing the Senior Notes, we may redeem some or all of the Senior Notes prior to their stated maturities, subject to certain limitations set forth in the indenture governing the applicable Senior Notes and, in certain cases, subject to significant prepayment premiums. We are obligated to offer to repurchase the Senior Notes at specified prices as a result of certain change-of-control events and a sale of all or substantially all of our assets. These restrictions and prohibitions are subject to certain qualifications and exceptions.

The indentures governing the Senior Notes, as well as Securitization Facility, contain covenants and restrictions that, among other things, limit our ability and the ability of any of the Guarantor Subsidiaries to (i) grant liens on our assets; (ii) make dividend payments, other distributions or other restricted payments; (iii) incur restrictions on the ability of the Guarantor Subsidiaries to pay dividends or make other payments or investments; (iv) enter into sale and leaseback transactions; (v) merge, consolidate, transfer or dispose of substantially all of their assets; (vi) incur additional indebtedness; (vii) use the proceeds from sales of assets, including capital stock of restricted subsidiaries (in the case of the Senior Notes); and (viii) enter into transactions with affiliates. We are currently in compliance with all covenants under our debt documents and expect to remain in compliance for the foreseeable future.

For further information on our long-term debt, see Note 10.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

Critical accounting policies are those accounting policies that can have a significant impact on the presentation of our financial condition and results of operations, and that require the use of complex and subjective estimates based upon past experience and management's judgment. Because of the uncertainty inherent in such estimates, actual results may differ from these estimates. Below are those policies applied in preparing our consolidated financial statements that management believes are the most dependent on the application of estimates and assumptions. For additional accounting policies, refer to Note 2 to the accompanying consolidated financial statements.

Revenue Recognition and Contract Balances

Our accounting policy regarding revenue recognition is disclosed in Note 2 to the consolidated financial statements. As described in Note 2, for certain contracts and performance obligations, we are required to exercise judgment when developing assumptions regarding expected total costs to fulfill performance obligations, variable consideration, and the standalone selling price of a performance obligation. Specifically, assumptions regarding the total costs require significant judgment with regard to materials, labor, and overhead costs that are affected by our ability to achieve technical requirements and schedule requirements, as well as our estimation of internal and subcontractor performance projections, anticipated volume, asset utilization, labor agreements, and inflation trends. We continually review and update our assumptions based on market trends and program performance. When we satisfy a performance obligation and recognize revenue over time, material changes in assumptions may result in positive or negative cumulative catch-up adjustments related to revenues previously recognized or, in some cases, forward loss contract reserves.

Commitments and Contingencies

Our results of operations could be affected by significant litigation adverse to the Company, including product liability claims, patent infringement, and claims for third-party property damage or personal injury stemming from alleged environmental torts. We record accruals for legal matters or other potential loss contingencies when the information available indicates that it is probable that a liability has been incurred and the amount of the loss can be reasonably estimated. We make adjustments to these accruals to reflect the impact and status of negotiations, settlements, rulings, advice of counsel, and other information or events that may pertain to a particular matter. Predicting the outcome of claims and lawsuits and estimating related costs and exposure involves substantial uncertainties that could cause actual costs to vary materially from estimates. In making determinations of likely outcomes of litigation matters, management considers many factors. These factors include, but are not limited to, the nature of specific claims including unasserted claims, our experience with similar types of claims, the jurisdiction in which the matter is filed, input from outside legal counsel, the likelihood of resolving the matter through alternative dispute resolution mechanisms or commercial negotiations, and the matter's status. Considerable judgment is required in determining whether to establish a contingent loss accrual when an adverse judgment is rendered against the Company in a court proceeding. In such situations, we will not recognize a loss if, based upon a thorough review of all relevant facts and information, management believes that it is probable that the pending judgment will be successfully overturned on appeal. Refer to Note 17 for further disclosure regarding commitments and contingencies.

Goodwill and Intangible Assets

Refer to Note 2 and Note 7 for details on our goodwill and intangible asset accounting policies. As disclosed in Note 7, as of March 31, 2023, Interiors (formerly Aerospace Structures) had goodwill of $475.3 million which was fully impaired during fiscal year 2018. The goodwill of one of the reporting units within Systems & Support had goodwill of $66.1 million which was fully impaired during fiscal year 2020. No reporting units have goodwill with a material carrying value that is at risk of impairment as of March 31, 2023.

We review identified intangible assets with definite lives and subject to amortization for impairment whenever events or changes in circumstances indicate that the related carrying amounts may not be recoverable. Determining whether an impairment loss has occurred requires the use of our internal forecast to estimate future cash flows and the useful life over which these cash flows will occur. As disclosed in Note 2, in May 2020, we concluded that the planned divestitures of our composites manufacturing operations located in Milledgeville, Georgia and Rayong, Thailand, represented a significant change in the manner in which the related asset group was expected to be used and that the asset group therefore needed to be tested for recoverability and impairment. We applied a discount rate of 15.0% to the estimated future excess earnings and cash flows of the asset group in order to estimate the fair value of the asset group as of the measurement date and recognized a total noncash impairment charge of $252.4 million, primarily allocated to definite-lived intangible assets.

Postretirement Plans

Certain of our current and former employees participate in defined benefit pension and other postretirement defined benefit plans (collectively, referred to as “defined benefit plans”) in the United States and the United Kingdom, which we sponsor. The determination of projected benefit obligations and the recognition of expenses related to defined benefit pension plans are dependent on various assumptions. The most significant of these assumptions are the discount rates and the long-term expected

34

rates of return on plan assets. Actual results that differ from our assumptions are accumulated and amortized for each plan to the extent required over the estimated future life expectancy of plan participants. We could be required to make future contributions to our defined benefit pension and post-retirement benefit plans as a result of adverse changes in interest rates and the capital markets. Adverse changes in the securities markets or interest rates, changes in actuarial assumptions, and legislative or other regulatory actions could substantially increase the costs of these plans and could result in a requirement to contribute additional funds to the plans. The Company regularly explores alternative solutions to meet its global pension obligations in the most cost-effective manner possible as demographics, life expectancy and country-specific pension funding rules change.

Significant Assumptions

We develop assumptions using relevant experience, in conjunction with market-related data for each plan. Assumptions are reviewed annually with third party consultants and adjusted as appropriate. Refer to Note 15 for details regarding the assumptions used to estimate projected benefit obligations and net periodic benefit cost as they pertain to our defined benefit pension plans.

Expected Return on Plan Assets

We determine our expected return on plan assets by evaluating both historical returns and estimates of future returns. Specifically, we consider the plan’s actual historical annual return on assets and historical broad market returns over long-term time frames based on our strategic allocation, which is detailed in Note 15. Future returns are based on independent estimates of long-term asset class returns. Based on this approach, the weighted average long-term expected annual rate of return on assets was estimated at 7.94% and 7.91% for fiscal years 2023 and 2022, respectively.

Discount Rate

The discount rate is used to calculate the present value of expected future benefit payments at the measurement date. A decrease in the discount rate increases the present value of benefit obligations and generally decreases pension expense. The discount rate assumption is based on current investment yields of high-quality fixed income investments during the retirement benefits maturity period. The pension discount rate is determined by considering an interest rate yield curve comprising AAA/AA bonds, with maturities between zero and thirty years, developed by the plan’s actuaries. Annual benefit payments are then discounted to present value using this yield curve to develop a single discount rate matching the plan’s characteristics. The discount rate assumption will change from measurement date to measurement date as market yields on high quality corporate bonds change.

Sensitivity Analysis

Pension Expense

A 25 basis point change in each of the long-term expected rate of return on plan assets and discount rate would have the following effect on the combined U.S. defined benefit pension plans’ pension income for the next 12 months:

	(Decrease)/Increase in Pension Income
	25 Basis Point Increase			25 Basis Point Decrease
	(In thousands)
Expected long-term rate of return on plan assets	$	3,304		$	(3,304	)
Discount rate	$	(176	)	$	204

Projected Benefit Obligation

Funded status is derived by subtracting the respective year-end values of the projected benefit obligations (“PBO”) from the fair value of plan assets. The sensitivity of the PBO to changes in the discount rate varies depending on the magnitude and direction of the change in the discount rate. Refer to Note 15 for a quantitative sensitivity analysis for the PBO.

Income Tax

We follow ASC 740, Income Taxes, which prescribes a recognition threshold and measurement attribute criteria for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return, as well as guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition.

We recognize deferred tax assets and liabilities based on the differences between the financial statement basis and the tax basis of assets, liabilities, net operating losses and tax carryforwards. A valuation allowance is required to be recognized to reduce the recorded deferred tax asset to the amount that will more likely than not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income by jurisdiction during the periods in which those temporary differences

35

become deductible or when carryforwards can be utilized. We consider the scheduled reversal of deferred tax liabilities, projected future taxable income and tax planning strategies in this assessment. As of March 31, 2023, we have a valuation allowance against substantially all of our net deferred tax assets given the insufficient positive evidence to support the realization of our deferred tax assets. A reduction in the valuation allowance could result in a significant decrease in income tax expense in the period that the reduction is recorded. However, the exact timing and amount of the reduction in our valuation allowance are unknown at this time and will be subject to the earnings level we achieve as well as our projected income in future periods.

Recently Issued Accounting Pronouncements

Refer to Note 1 for disclosure of the effects of recently issued accounting guidance, if any, that are significant to our financial reporting.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

Foreign Exchange Risk

We are subject to foreign currency exchange rate risk relating to receipts from customers and payments to suppliers in foreign currencies. We use foreign currency forward contracts to hedge the price risk associated with forecasted foreign denominated payments related to our ongoing business. Foreign currency forward contracts are sensitive to changes in foreign currency exchange rates. At March 31, 2023, a 10% change in the exchange rate in our portfolio of foreign currency contracts would not have a material impact on the unrecognized gains or losses recognized within operating income. Consistent with the use of these contracts to neutralize the effect of exchange rate fluctuations, such unrealized losses or gains would be offset by corresponding gains or losses, respectively, in the remeasurement of the underlying transactions being hedged. When taken together, these forward currency contracts and the offsetting underlying commitments do not create material market risk.

Interest Rate Risk

Our exposure to market risk for changes in interest rates relates primarily to our long-term debt. Our long-term debt is carried at amortized cost and fluctuations in interest rates do not impact our consolidated financial statements. However, the fair value of our outstanding debt, which pays interest at a fixed rate, will generally fluctuate with movements of interest rates, increasing in periods of declining rates of interest and declining in periods of increasing rates of interest. The information below summarizes our market risks associated with debt obligations and should be read in conjunction with Note 10 of the notes to the accompanying consolidated financial statements.

The following table presents principal cash flows and the related interest rates. Fixed interest rates disclosed represent the weighted average rate as of March 31, 2023.

Item 8. Financial Statements and Supplementary Data

Report of Independent Registered Public Accounting Firm

To the Stockholders and Board of Directors of Triumph Group, Inc.:

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Triumph Group, Inc. (the Company) as of March 31, 2023 and 2022, the related consolidated statements of operations, comprehensive (loss) income, stockholders' deficit and cash flows for each of the three years in the period ended March 31, 2023, and the related notes and financial statement schedule listed in the Index at Item 15(a) (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at March 31, 2023 and 2022, and the results of its operations and its cash flows for each of the three years in the period ended March 31, 2023, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of March 31, 2023, based on criteria established in Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) and our report dated May 23, 2023, expressed an unqualified opinion thereon.

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures include examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matters

The critical audit matters communicated below are matters arising from the current period audit of the financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

Realizability of Deferred Tax Assets

Description of the Matter As described in Note 12 of the consolidated financial statements, at March 31, 2023, the Company had deferred tax assets for deductible temporary differences and tax attributes of $39.1 million (net of a $512.6 million valuation allowance). Deferred tax assets are reduced by a valuation allowance if, based upon the weight of all available evidence, it is more likely than not that some portion, or all, of the deferred tax assets will not be realized. Auditing the Company’s analysis of the realizability of its deferred tax assets required complex auditor judgment because the amounts are material to the financial statements and the assessment process involves significant judgment to apply changes in the tax law, determine the future reversal pattern of existing taxable temporary differences and other assumptions of future taxable income that may be affected by future market or economic conditions.  

37

How We Addressed the Matter in Our Audit We obtained an understanding, evaluated the design, and tested the operating effectiveness of controls that address the risks of material misstatement relating to the realizability of deferred tax assets. This included controls over management’s evaluation and application of the effects of changes in the tax law and the scheduling of the future reversal pattern of existing taxable temporary differences that have been identified as a source of future taxable income. To test the Company’s assessment of the realizability of deferred tax assets and the resulting valuation allowance, our audit procedures included, among others, testing the Company’s calculation of future taxable income from the reversal of existing temporary taxable differences and evaluating the scheduling of the reversal patterns. In addition, we compared taxable income in prior carryback years, if any, to the Company’s income tax returns; considered the feasibility of tax planning strategies; and, evaluated projected future taxable income exclusive of reversing temporary differences and carryforwards. We involved our tax professionals to assist in evaluating the application of tax law, including any changes in the tax law, in the Company’s consideration of the sources of future taxable income.

Defined Benefit Pension Obligations

Description of the Matter

At March 31, 2023, the Company’s aggregate defined benefit pension obligation was $1.7 billion and the net periodic benefit income was $24.5 million. As described in Note 15 of the consolidated financial statements, the Company updates the estimates used to measure the defined benefit pension obligation and plan assets in the fourth quarter and upon a remeasurement event to reflect the actual return on plan assets and updated actuarial assumptions. Auditing the defined benefit pension obligations and the related net periodic benefit income required complex auditor judgment and technical expertise due to the highly judgmental nature of the actuarial assumptions (e.g., discount rate, mortality rate, expected return on plan assets) used in the measurement process. These assumptions had a significant effect on the projected benefit obligation and the net periodic benefit income.

How We Addressed the Matter in Our Audit

We obtained an understanding, evaluated the design and tested the operating effectiveness of controls over management’s determination of the defined benefit pension obligation calculations, the significant actuarial assumptions described above and the data inputs provided to the Company’s actuarial specialists. To test the defined benefit pension benefit obligation, and the related net periodic benefit income, our audit procedures included, among others, evaluating the methodology used, the significant actuarial assumptions described above, the underlying data used by management and its actuaries and the appropriateness of management’s judgments in applying the authoritative accounting literature. We compared the actuarial assumptions used by management to historical trends and evaluated the change in the defined benefit pension from prior year resulting from the change in service cost, interest cost, benefit payments, and actuarial gains and losses. In addition, we involved our actuarial specialists to assist in evaluating management’s methodology for determining the actuarial assumptions. For example, we evaluated management’s methodology for determining the discount rate that reflects the maturity and duration of the benefit payments and is used to measure the defined benefit pension obligation. As part of this assessment, we compared the projected defined benefit pension cash flows to prior year amounts and compared the current year benefits paid to the prior year projected cash flows. To evaluate the mortality rate, we assessed whether the information is consistent with publicly available information, and whether any market data adjusted for entity-specific adjustments were applied. We also tested the completeness and accuracy of the underlying data, including the participant data provided to the Company’s actuarial specialists. Lastly, to evaluate the expected return on plan assets, we assessed whether management’s assumptions were consistent with a range of returns for a portfolio of comparative investments.

We have served as the Company’s auditor since 1993.

1. BACKGROUND AND BASIS OF PRESENTATION

Triumph Group, Inc. ("Triumph" or the "Company") is a Delaware corporation which, through its operating subsidiaries, designs, engineers, manufactures and sells products for the global aerospace OEMs of aircraft and aircraft components and repairs and overhauls aircraft components and accessories for commercial airline, air cargo carrier and military customers on a worldwide basis. Triumph and its subsidiaries (collectively, the "Company") are organized based on the products and services that they provide. The Company has two reportable segments: Systems & Support and Interiors (formerly Aerospace Structures).

Systems & Support consists of the Company’s operations that provide integrated solutions, including design; development; and support of proprietary components, subsystems and systems, as well as production of complex assemblies using external designs. 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 heat exchange technology; fuel pumps, fuel metering units, and Full Authority Digital Electronic Control fuel systems; and hydromechanical and electromechanical primary and secondary flight controls. Systems & Support also provides full life cycle solutions for commercial, regional, and military aircraft. The Company’s 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 post-production supply chain activities, Systems & Support is positioned to provide integrated planeside repair solutions globally. Capabilities include repair services for metallic and composite aircraft structures; nacelles; thrust reversers; interiors; auxiliary power units; and a wide variety of pneumatic, hydraulic, fuel, and mechanical accessories. Repair services generally involve the replacement and/or remanufacturing of parts, which is similar to the original manufacture of the part. The processes that the Company performs related to repair and overhaul services are essentially the repair of wear parts or replacement of parts that are beyond economic repair. The repair service generally involves remanufacturing a complete part or a component of a part.

Interiors (formerly Aerospace Structures) consists of the Company’s operations that have historically supplied commercial, business, and regional manufacturers with large metallic structures and continues to supply aircraft interior systems, including air ducting and thermal acoustic insulations systems. Subsequent to the divestitures disclosed in Note 3, the remaining operations of Interiors (formerly Aerospace Structures) are those that supply commercial and regional manufacturers with aircraft interior systems.

The accompanying consolidated financial statements include the accounts of Triumph and its wholly-owned subsidiaries. Intercompany accounts and transactions have been eliminated from the consolidated financial statements.

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Cash and Cash Equivalents

Cash equivalents consist of highly liquid investments with a maturity of three months or less at the time of purchase. Fair value of cash equivalents approximates carrying value.

Trade and Other Receivables, net

Trade and other receivables are recorded net of an allowance for expected credit losses. Trade and other receivables include amounts billed and currently due from customers and amounts retained by the customer pending contract completion. The Company performs ongoing credit evaluations of its customers and generally does not require collateral. The Company pools receivables that share underlying risk characteristics and records the allowance for expected credit losses based on a combination of prior experience, current economic conditions and management’s expectations of future economic conditions, and specific collectibility matters when they arise. The Company writes off balances against the allowance for expected credit losses when collectibility is deemed remote. The Company's trade and other receivables are exposed to credit risk; however, the risk is limited due to the diversity of the customer base. For the years ended March 31, 2023 and 2022, credit loss expense and write-offs were immaterial.

Goodwill and Intangible Assets

The Company accounts for goodwill and intangible assets in accordance with ASC 350, Intangibles—Goodwill and Other. Under ASC 350, goodwill and intangible assets with indefinite lives are not amortized; rather, they are tested for impairment on at least an annual basis. Intangible assets with finite lives are amortized over their useful lives.

The Company assesses whether goodwill impairment exists using both the qualitative and quantitative assessments. The qualitative assessment involves determining whether events or circumstances exist that indicate it is more likely than not that the fair value of a reporting unit is less than its carrying amount, including goodwill. If based on this qualitative assessment the Company determines it is more likely than not that the fair value of a reporting unit is less than its carrying amount or if the Company elects not to perform a qualitative assessment, a quantitative assessment is performed as required by ASC 350 to determine whether a goodwill impairment exists at the reporting unit.

The quantitative test is used to compare the carrying amount of the reporting unit's assets to the fair value of the reporting unit. If the fair value exceeds the carrying value, no further evaluation is required, and no impairment loss is recognized. If the carrying amount exceeds the fair value, then an impairment loss occurs. The impairment is measured by using the amount by which the carrying value exceeds the fair value not to exceed the amount of recorded goodwill. The determination of the fair value of its reporting units is based, among other things, on estimates of future operating performance of the reporting unit being valued. The Company is required to complete an impairment test for goodwill and record any resulting impairment losses at least annually. Changes in market conditions, among other factors, may have an impact on these estimates and require interim impairment assessments.

When performing the quantitative impairment test, the Company's methodology includes the use of an income approach which discounts future net cash flows to their present value at a rate that reflects the Company's cost of capital, otherwise known as the discounted cash flow method ("DCF"). These estimated fair values are based on estimates of future cash flows of the businesses. Factors affecting these future cash flows include the continued market acceptance of the products and services offered by the businesses, the development of new products and services by the businesses and the underlying cost of development, the future cost structure of the businesses and future technological changes. The Company also incorporates market multiples for comparable companies in determining the fair value of its reporting units. Any such impairment would be recognized in full in the reporting period in which it has been identified. The fair value estimates resulting from the application of these methodologies are based on inputs classified within Level 3 of the fair value hierarchy, as described below.

During the fourth quarter of the fiscal years ended March 31, 2023 and 2022, the Company performed its annual goodwill impairment assessment for each of its reporting units with no impairment identified.

Finite-lived intangible assets are amortized over their useful lives ranging from 10 to 30 years. The Company continually evaluates whether events or circumstances have occurred that would indicate that the remaining estimated useful lives of long-lived assets, including intangible assets, may warrant revision or that the remaining balance may not be recoverable. Long-lived assets are evaluated for indicators of impairment. When factors indicate that long-lived assets, including intangible assets, should be evaluated for possible impairment, an estimate of the related undiscounted cash flows over the remaining life of the long-lived assets, including intangible assets, is used to measure recoverability based on the primary asset of the asset group. Some of the more important factors management considers include the Company's financial performance relative to expected and historical performance, significant changes in the way the Company manages its operations, negative events that have occurred, and negative industry and economic trends. If the estimated undiscounted cash flows are less than the carrying amount, measurement of the impairment will be based on the difference between the carrying value and fair value of the asset group, generally determined based on the present value of expected future cash flows associated with the use of the asset.

In fiscal 2021, the Company's Board of Directors committed to a plan (i) to sell its composites manufacturing operations located in Milledgeville, Georgia, and Rayong, Thailand, and (ii) to transfer the assets and certain liabilities associated with its Gulfstream G650 wing supply chain activities (as disclosed in Note 3, this transaction closed in August 2020). These planned divestitures

represented the divestiture of certain assets and liabilities of an operating business within the Interiors (formerly Aerospace Structures) segment that the Company had identified as an asset group pursuant to the provisions of ASC 360, Property, Plant, and Equipment. As a result, as of May 31, 2020, the Company concluded that the planned divestitures represented a significant change in the manner in which the related asset group was expected to be used, and that the asset group therefore needed to be tested for recoverability. The asset group primarily consisted of working capital, fixed assets and definite-lived intangible assets. The Company first determined that the relevant long-lived asset group was not recoverable by comparing the undiscounted cash flows expected to be generated by the long-lived asset group to the carrying value of the asset group. As a result, the Company estimated the fair value of the long-lived asset group and concluded that the asset group was impaired. The Company used a multi-period excess earnings approach to estimate the fair value of the long-lived asset group for purposes of testing the asset group for impairment. This method estimates fair value based on the expected future excess earnings stream attributable to the asset group. This method requires the use of several key assumptions, including revenue projections that consider historical and estimated future results, general economic and market conditions, as well as the impact of planned business and operational strategies. A discount rate of 15.0% was applied to the estimated future excess earnings and cash flows in order to estimate the fair value of the asset group as of the measurement date. The Company has determined that the lowest level of the inputs that are significant to the fair value measurement are unobservable inputs that fall within Level 3 of the fair value hierarchy.

In accordance with ASC 360, the Company allocated the resulting impairment to the specific long-lived assets within the asset group on a pro rata basis, except that the loss allocated to an individual long-lived asset of the group did not reduce the carrying amount of that asset below its estimated fair value. As a result, the Company recognized a total noncash impairment charge of $252,382 in the first quarter, primarily allocated to definite-lived intangible assets, which is presented as “Impairment of long-lived assets” on the accompanying consolidated statements of operations. In January 2021, the Company’s Board of Directors committed to a plan to sell its manufacturing operations located in Red Oak, Texas. As a result of this decision and the resulting classification of this disposal group as held for sale, the Company fully impaired the remaining customer relationship intangible asset within the Interiors (formerly Aerospace Structures) segment and recognized a noncash impairment charge of $6,696, which has been included in the impairment on the assets held for sale as disclosed in Note 3 and is presented within “(Gain) loss on sale of assets and businesses” on the accompanying consolidated statement of operations.

See below for the Company's accounting policy regarding fair value measurements and the definition of fair value levels.

Revenue Recognition and Contract Balances

The Company's revenue is principally from contracts with customers to provide design, development, manufacturing, and support services associated with specific customer programs. The Company regularly enters into long-term master supply agreements that establish general terms and conditions and may define specific program requirements. Many agreements include clauses that provide sole supplier status to the Company for the duration of the program’s life. Purchase orders (or authorizations to proceed) are issued pursuant to the master supply agreements. Additionally, a majority of the Company’s agreements with customers include options for future purchases. Such options primarily reduce the administrative effort of issuing subsequent purchase orders and do not represent material rights granted to customers. The Company generally enters into agreements directly with its customers and is the principal in all current contracts.

The identification of a contract with a customer for purposes of accounting and financial reporting requires an evaluation of the terms and conditions of agreements to determine whether presently enforceable rights and obligations exist. Management considers a number of factors when making this evaluation that include, but are not limited to, the nature and substance of the business exchange, the specific contractual terms and conditions, the promised products and services, the termination provisions in the contract, as well as the nature and execution of the customer’s ordering process and how the Company is authorized to perform work. Generally, presently enforceable rights and obligations are not created until a purchase order is issued by a customer for a specified number of units of product or services. Therefore, the issuance of a purchase order is generally the point at which a contract is identified for accounting and financial reporting purposes.

(Dollars in thousands, except per share data)

Management identifies the promises to the customer. Promises are generally explicitly stated in each contract, but management also evaluates whether any promises are implied based on the terms of the agreement, past business practice, or other facts and circumstances. Each promise is evaluated to determine if it is a performance obligation. A performance obligation is a promise in a contract to transfer a distinct good or service. The Company considers a number of factors when determining whether a promise is a distinct performance obligation, including whether the customer can benefit from the good or service on its own or together with other resources that are readily available to the customer, whether the Company provides a significant service of integrating goods or services to deliver a combined output to the customer, or whether the goods or services are highly interdependent. The Company’s performance obligations consist of a wide range of engineering design services and manufactured components, as well as spare parts and repairs for OEMs.

The transaction price for a contract reflects the consideration the Company expects to receive for fully satisfying the performance obligations in the contract. Typically, the transaction price consists solely of fixed consideration but may include variable consideration for contractual provisions such as unpriced contract modifications, cost-sharing provisions, and other receipts or payments to customers. The Company identifies and estimates variable consideration, typically at the most likely amount the Company expects to receive from its customers. Variable consideration is only included in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized for the contract will not occur, or when the uncertainty associated with the variable consideration is resolved. Consideration paid or payable to a customer is reflected as a reduction in net revenues when the amounts paid are not related to a distinct good or service at the later of when the related revenue is recognized or when the Company pays or promises to pay the consideration to the customer. The Company's contracts with customers generally require payment under normal commercial terms after delivery with payment typically required within 30 to 120 days of delivery.

The Company generally is not subject to collecting sales tax and has made an accounting policy election to exclude from the transaction price any sales and other similar taxes collected from customers. As a result, any such collections are accounted for on a net basis.

The total transaction price is allocated to each of the identified performance obligations using the relative stand-alone selling price. The objective of the allocation is to reflect the consideration that the Company expects to receive in exchange for the products or services associated with each performance obligation. Stand-alone selling price is the price at which the Company would sell a promised good or service separately to a customer. Stand-alone selling prices are established at contract inception, and subsequent changes in transaction price are allocated on the same basis as at contract inception. When stand-alone selling prices for the Company’s products and services are not observable, the Company uses either the “Expected Cost Plus a Margin” or "Adjusted Market Assessment" approaches to estimate stand-alone selling price. Expected costs are typically derived from the available periodic forecast information.

Revenue is recognized when or as control of promised products or services transfers to a customer and is recognized at the amount allocated to each performance obligation associated with the transferred products or services. Service sales, principally representing repair, maintenance, and engineering activities are recognized over the contractual period or as services are rendered. Sales under long-term contracts with performance obligations satisfied over time are recognized using either an input or output method. The Company recognizes revenue over time as it performs on these contracts because of the continuous transfer of control to the customer as represented by contractual terms that entitle the Company to the reimbursement of costs plus a reasonable profit for work performed to manufacture products for which the Company has no alternate use or for work performed on a customer-owned asset.

With control transferring over time, revenue is recognized based on the extent of progress toward completion of the performance obligation. The Company generally uses the cost-to-cost input method of progress for its contracts because it best depicts the transfer of control to the customer that occurs as work progresses. Under the cost-to-cost method, the extent of progress toward completion is measured based on the proportion of costs incurred to date to the total estimated costs at completion of the performance obligation. The Company reviews its cost estimates on contracts on a periodic basis, or when circumstances change and warrant a modification to a previous estimate. Cost estimates are largely based on negotiated or estimated purchase contract terms, historical performance trends and other economic projections. Significant factors that influence these estimates include inflationary trends, technical and schedule risk, internal and subcontractor performance trends, business volume assumptions, asset utilization, and anticipated labor agreements.

Revenue and cost estimates are regularly monitored and revised based on changes in circumstances. Impacts from changes in estimates of net sales and cost of sales are recognized on a cumulative catch-up basis, which recognizes in the current period the cumulative effect of the changes on current and prior periods based on a performance obligation’s percentage of completion. Forward loss reserves for anticipated losses on long-term contracts are recorded in full when such losses become evident, to the extent required and are included in contract liabilities on the accompanying consolidated balance sheets. The Company believes

47

Triumph Group, Inc.

Notes to Consolidated Financial Statements

(Dollars in thousands, except per share data)

that the accounting estimates and assumptions made by management are appropriate, however actual results could differ materially from those estimates.

For the fiscal year ended March 31, 2023, cumulative catch-up adjustments resulting from changes in contract values and estimated costs that arose during the fiscal year increased revenue, operating income, net income, and diluted earnings per share by approximately $21,208, $27,963, $27,963, and $0.39, respectively. The cumulative catch-up adjustments to operating income for the fiscal year ended March 31, 2023, included gross favorable adjustments of approximately $32,699 and gross unfavorable adjustments of approximately $4,736.

For the fiscal year ended March 31, 2022, cumulative catch-up adjustments resulting from changes in estimates increased revenue and decreased operating loss, net loss, and diluted loss per share by approximately $6,884, $16,042, $16,042, and $0.25, respectively. The cumulative catch-up adjustments to operating income for the fiscal year ended March 31, 2022, included gross favorable adjustments of approximately $30,560 and gross unfavorable adjustments of approximately $14,518.

For the fiscal year ended March 31, 2021, cumulative catch-up adjustments resulting from changes in estimates increased revenue and decreased operating loss, net loss, and diluted loss per share by approximately $4,796, $12,332, $12,332, and $0.23, respectively. The cumulative catch-up adjustments to operating income for the fiscal year ended March 31, 2021, included gross favorable adjustments of approximately $55,180 and gross unfavorable adjustments of approximately $42,848.

Revenues for performance obligations that are not recognized over time are recognized at the point in time when control transfers to the customer. For performance obligations that are satisfied at a point in time, the Company evaluates the point in time when the customer can direct the use of and obtain the benefits from the products and services. Generally, the shipping terms determine the point in time when control transfers to customers. Shipping and handling activities are not considered performance obligations and related costs are included in cost of sales as incurred.

Differences in the timing of revenue recognition and contractual billing and payment terms result in the recognition contract assets and liabilities. Refer to Note 4 for further discussion.

Warrants

On December 1, 2022, the Company’s board of directors declared a distribution to holders of the Company’s shares of common stock in the form of warrants to purchase shares of common stock (the “Warrants”). Holders of common stock received three Warrants for every ten shares of common stock held as of December 12, 2022 (the "Record Date") (rounded down for any fractional warrant). The Company issued approximately 19.5 million Warrants on December 19, 2022, to holders of record of common stock as of the close of business on the Record Date. The Warrants trade on the over-the-counter market.

Each Warrant represents the right to purchase initially one share of common stock, subject to certain anti-dilution adjustments (“Warrant Shares Per Warrant”), at an exercise price of $12.35 per Warrant (the “Exercise Price”), subject to certain anti-dilution adjustments (the “Implied Per Share Exercise Price”). Payment for shares of common stock on exercise of Warrants may be in (i) cash or (ii) under certain circumstances, Designated Notes (as defined below). In the event Designated Notes are used to pay for the exercise of the Warrants, accrued interest (in addition to the stated aggregate principal amount) will be forfeited upon exercise, unless exercise occurs after a record date for the payment of interest and before the resulting scheduled payment date (in which case note holders will receive the scheduled interest payment). If all Warrants were exercised and settled as of March 31, 2023, the Company would be required to issue approximately 19.1 million shares (assuming no over-exercise options, as described below, were exercised). The closing price of the Company’s shares of common stock was $11.59 as of March 31, 2023.

“Designated Notes” means, collectively, any of the issued and outstanding notes of the Company as designated or undesignated by the Company from time to time; provided that any designation by the Company of a particular series of notes as “Designated Notes” shall retain such designation for a minimum of 20 consecutive business days from (and including) the date of publication of notice of the same by press release. The Company also has the right, but not obligation, to remove one or more series of its notes from being “Designated Notes,” but such redesignation shall only be effective 20 consecutive business days from (and including) the date of publication of notice of the same by press release. The Company initially designated the following notes as “Designated Notes,” each as defined in above: the 2024 First Lien Notes, the 2024 Second Lien Notes, and the 2025 Notes. On February 3, 2023, the Company published a press release announcing the de-designation of the 2024 First Lien Notes and the 2024 Second Lien Notes.

Pursuant to the terms of the Warrant Agreement, a holder may elect to pay an additional amount equal to $1.8525 (being 0.15 multiplied by the Exercise Price) in exchange for an additional number of shares of common stock equal to the product of 0.15 and the Warrant Shares Per Warrant applicable to the relevant exercise on the terms specified in the Warrant Agreement. If all Warrants were exercised as of March 31, 2023 and each holder were to elect to pay the additional $1.8525 to receive additional

48

Triumph Group, Inc.

Notes to Consolidated Financial Statements

(Dollars in thousands, except per share data)

shares, the Company would be required to issue an additional approximately 2.9 million shares in settlement of the incremental exercise price received.

The Warrants expire on December 19, 2023, subject to (i) the right of the Company to redeem the Warrants on not less than 20 calendar days’ notice (any such date of redemption, the “Redemption Date” and any such date of notice a “Redemption Notice”) at a price of 1/10 of $0.01 per Warrant and (ii) the automatic acceleration of the Expiration Date following the Price Condition Date, as defined and described below.

Unless the Company has previously issued a Redemption Notice with respect to the Warrants, then following the last day of the first 30 consecutive trading day period to occur in which daily volume weighted average prices of the shares of Common Stock has been at least equal to the then applicable Implied Per Share Exercise Price on each of 20 trading days (whether or not consecutive) (the “Price Condition”), the Expiration Date will automatically accelerate to the date that is the 5th business day following the Price Condition Date; provided that the Company may, at its sole option, elect a later Expiration Date by providing public notice no later than the Price Condition Date. The “Price Condition Date” is the first business day following the last Trading Day of the period in which the Price Condition is met.

Any holder that exercises any Warrants from and after (a) 5:00 p.m. New York city time on the earlier of (x) a Price Condition Date and (y) the date that the Company issues a Redemption Notice until (b) 5:00 p.m. New York City time on, as applicable, (x) the Expiration Date and (y) the business day immediately preceding the Redemption Date (the last day of such period, the “Over-Subscription Deadline”), may, subject to the terms of the Warrant Agreement, elect to subscribe for any or all of the shares of Common Stock issuable pursuant to any outstanding but unexercised Warrants as of the Over-Subscription Deadline (the “Over-Subscription Privilege”). To exercise the Over-Subscription Privilege, a holder must deliver an amount in cash equal to the elected over-subscription shares multiplied by the then applicable Implied Per Share Exercise Price (such amount, the “Elected Over-Subscription Shares Amount”) at the same time as the basic warrant exercise right is exercised. Any excess payments received will be returned, without interest, promptly following the settlement date.

An ownership limitation is in place such that a holder of Warrants is not permitted to exercise Warrants for any shares of common stock if following such exercise the holder will have beneficial ownership of common stock in excess of 4.9% of the then issued and outstanding common stock (excluding shares held by subsidiaries); provided, that a holder of Common Stock in excess of 4.9% of the issued and outstanding common stock as of 5:00 p.m. New York City time on December 1, 2022 will be entitled to exercise Warrants received in the Warrant Distribution, but only to the extent such holder’s receipt of such common stock is permitted by a waiver in effect at such time that constitutes “Prior Approval of the Company” under the Tax Benefit Preservation Plan, dated March 11, 2022, between the Company and Computershare Trust Company, N.A., as rights agent.

The Exercise Price and the number of shares of common stock issuable upon exercise are subject to certain anti-dilution adjustments, including for share dividends, splits, subdivisions, spin-offs, consolidations, reclassifications, combinations, noncash distributions, and cash dividends.

The common stock warrants are accounted for as derivative liabilities in accordance with ASC 815-40 and included within accrued liabilities on the accompanying condensed consolidated balance sheets. The Company measured the Warrants at fair value as of the issuance date using a Monte Carlo pricing model, a Level 3 fair value measurement (as described below), due to the level of market activity. Inherent in the option pricing simulation are assumptions related to expected stock-price volatility, expected life and risk-free interest rate. The Company estimates the volatility of the Warrants based on implied and historical volatility of the Company’s common stock. The risk-free interest rate is based on the U.S. Treasury zero-coupon yield curve on the grant date for a maturity similar to the expected remaining life of the Warrants. The expected life of the Warrants is based on the Company’s ability to redeem the Warrants, subject to a 20 calendar-day notice period, as well as the automatic acceleration of the Expiration Date following the Price Condition Date. During the three months ended December 31, 2022, due to increased trading volume, the Company began remeasuring outstanding Warrants using the Warrants trading price, a Level 1 fair value measurement (as described below). The Warrants are remeasured at each balance sheet date. Warrants remeasurement adjustments are recognized in warrants remeasurement gain, net on the accompanying condensed consolidated statements of operations.

At distribution, the fair value of the Warrants was $19,500. At March 31, 2023, the fair value of the Warrants was approximately $9,563 and $9,796 of warrants remeasurement gain has been recognized in the year ended March 31, 2023. Following the issuance on December 19, 2022 through March 31, 2023, approximately 0.4 million Warrants have been exercised

Leases

The Company leases office space, manufacturing facilities, land, vehicles, and equipment. The Company determines if an agreement is or contains a lease at the lease inception date and recognizes right-of-use assets (“ROU”) and lease liabilities at the

49

Notes to Consolidated Financial Statements

(Dollars in thousands, except per share data)

lease commencement date. A ROU asset and corresponding lease liability are not recorded for leases with an initial term of 12 months or less (“short-term leases”).

ROU assets represent the Company's right to use an underlying asset during the lease term, and lease liabilities represent the Company's obligation to make lease payments arising from the lease. The determination of the length of lease terms is affected by options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. The existence of significant economic incentive is the primary consideration when assessing whether the Company is reasonably certain of exercising an option in a lease. Both finance and operating lease ROU assets and liabilities are recognized at commencement date and measured as the present value of lease payments to be made over the lease term. As the interest rate implicit in the lease is not readily available for most of the Company's leases, the Company uses its estimated incremental borrowing rate in determining the present value of lease payments. The estimated incremental borrowing rate is derived from information available at the lease commencement date. The lease ROU asset recognized at commencement is adjusted for any lease payments related to initial direct costs, prepayments, and lease incentives.

For operating leases, lease expense is recognized on a straight-line basis over the lease term. For finance leases, lease expense comprises the amortization of the ROU assets recognized on a straight-line basis generally over the shorter of the lease term or the estimated useful life of the underlying asset and interest on the lease liability. Variable lease payments not dependent on a rate or index are recognized when the event, activity, or circumstance in the lease agreement upon which those payments are contingent is probable of occurring and are presented in the same line of the consolidated balance sheet as the rent expense arising from fixed payments. The Company has lease agreements with lease and non-lease components. Non-lease components are combined with the related lease components and accounted for as lease components for all classes of underlying assets.

Retirement Benefits

Defined benefit pension plans are recognized in the consolidated financial statements on an actuarial basis. A significant element in determining the Company's pension (income) expense is the expected long-term rate of return on plan assets. This expected return is an assumption as to the average rate of earnings expected on the funds invested or to be invested to provide for the benefits included in the projected pension benefit obligation. The Company applies this assumed long-term rate of return to a calculated value of plan assets, which recognizes changes in the fair value of plan assets in a systematic manner over five years. This produces the expected return on plan assets that is included in pension (income) expense. The difference between this expected return and the actual return on plan assets is deferred. The net deferral of past asset (losses) gains affects the calculated value of plan assets and, ultimately, future pension (income) expense.

The Company periodically experiences events or makes changes to its benefit plans that result in curtailment or special charges. Curtailments are recognized when events occur that significantly reduce the expected years of future service of present employees or eliminates the benefits for a significant number of employees for some or all of their future service.

Curtailment losses are recognized when it is probable the curtailment will occur and the effects are reasonably estimable. Curtailment gains are recognized when the related employees are terminated or a plan amendment is adopted, whichever is applicable.

From time to time, the Company may enter into transactions that relieve it of primary responsibility for all or more than a minor portion of certain of its pension benefit obligations. When these transactions are effected through an irrevocable action that relieves the Company of primary responsibility for its pension or other postretirement benefit obligations and eliminates significant risks related to the obligation and the related assets used to effect the transaction, they are considered settlements, as defined by ASC 715, Compensation – Retirement Benefits. When a transaction meets the definition of a settlement, at the time of settlement the Company recognizes as a gain or loss the pro rata amount of the net gain or loss in accumulated other comprehensive loss based on the proportion of the projected benefit obligation settled to the total projected benefit obligation.

As required under ASC 715, the Company remeasures plan assets and obligations during an interim period whenever a significant event occurs that results in a material change in the net periodic pension cost. The determination of significance is based on judgment and consideration of events and circumstances impacting the pension costs.

At March 31 of each year, the Company determines the fair value of its pension plan assets as well as the discount rate to be used to calculate the present value of plan liabilities. The discount rate is an estimate of the interest rate at which the pension benefits could be effectively settled. In estimating the discount rate, the Company looks to rates of return on high-quality, fixed-income investments currently available and expected to be available during the period to maturity of the pension benefits. The Company uses a portfolio of fixed-income securities, which receive at least the second-highest rating given by a recognized ratings agency.

Contingencies

Contingences are existing conditions, situations or circumstances involving uncertainty as to possible gain or loss that will ultimately be resolved when future events occur or fail to occur. Such contingencies include, but are not limited to environmental obligations, litigation, regulatory investigations and proceedings, product quality, and gains or losses resulting from other events and developments. Liabilities for loss contingencies are accrued in the amount of its best estimate for the ultimate loss when a loss is considered probable of having been incurred and is reasonably estimable. When there appears to be a range of possible costs with equal likelihood, liabilities are based on the low-end of such range. Disclosure is provided for material loss contingencies when a loss is probable but a reasonable estimate cannot be made, and when it is reasonably possible that a loss will be incurred or the amount of a loss will exceed the recorded provision. The Company regularly reviews contingencies to determine whether the likelihood of loss has changed and to assess whether a reasonable estimate of the loss or range of loss can be made. Contingencies that might result in gains are generally not accrued until the contingencies are resolved and the gain is realized or realizable. Refer to Note 17 for further disclosure.

Fair Value Measurements

Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. When determining fair value measurements for assets and liabilities required to be recorded at fair value, the Company considers the principal or most advantageous market in which it would transact and also considers assumptions that market participants would use when pricing an asset or liability. The fair value hierarchy has three levels of inputs that may be used to measure fair value: Level 1—Unadjusted quoted prices in active markets for identical assets or liabilities; Level 2—Unadjusted quoted prices in active markets for similar assets or liabilities, or unadjusted quoted prices for identical or similar assets or liabilities in markets that are not active, or inputs other than quoted prices that are observable for the asset or liability; and Level 3—Unobservable inputs for the asset or liability. The Company has applied fair value measurements when measuring the warrants (refer to the above disclosure), when comparing the carrying value of assets held for sale with the related fair value less cost to sell (see Note 3), when measuring long-lived asset impairment in fiscal 2021 (see above within the disclosure of the Company’s goodwill and intangible asset accounting policies), when disclosing the fair value of its long-term debt not recorded at fair value (see Note 10) and when measuring its pension and postretirement plan assets (see Note 15).

Income Taxes

The Company accounts for income taxes using the asset and liability method. The asset and liability method requires recognition of deferred tax assets and liabilities for expected future tax consequences of temporary differences that currently exist between tax bases and financial reporting bases of the Company's assets and liabilities. A valuation allowance is provided on deferred taxes if it is determined that it is more likely than not that the asset will not be realized.

Management judgment is required to determine the amount of benefit to be recognized in relation to an uncertain tax position. The Company uses a two-step process to evaluate tax positions. The first step requires an entity to determine whether it is more likely than not (greater than 50% chance) that the tax position will be sustained. The second step requires an entity to recognize in the financial statements the benefit of a tax position that meets the more-likely-than-not recognition criterion. The amounts ultimately paid upon resolution of issues raised by taxing authorities may differ materially from the amounts accrued and may materially impact the financial statements of the Company in future periods. The Company recognizes penalties and interest accrued related to income tax liabilities in the provision for income taxes on its consolidated statements of operations.

Supplemental Cash Flow Information

In November 2021, the Company entered into an agreement with the DOT under the AMJP for a grant of up to $21,259. The receipt of the full award was primarily conditioned upon the Company committing to not furlough or lay off a defined group of employees during the six-month period of performance between November 2021 and May 2022. The Company received approximately $19,400 under the agreement, of which approximately $10,630 was received in the year ended March 31, 2022, and the remainder of which was received in the year ended March 31, 2023. In July 2022, the Company received a letter from the DOT confirming that the Company had satisfied the reporting requirements under the AMJP. In the twelve months ended March 31, 2023 and 2022, the Company recognized as a reduction in cost of sales approximately $5,300 and $14,064, respectively, the former representing the final balance of the earned grant benefit.

For the fiscal years ended March 31, 2023, 2022, and 2021, the Company paid $4,565, $5,382, and $2,297, respectively, for income taxes, net of income tax refunds received.

3. DIVESTED OPERATIONS AND ASSETS HELD FOR SALE

Fiscal 2023 Divestitures

In January 2022, the Company’s Board of Directors committed to a plan to sell its manufacturing operations located in Stuart, Florida. In February 2022, the Company entered into a definitive agreement with the buyer of these manufacturing operations. This transaction closed in July 2022. The Company recognized a gain of approximately $96,800, net of transaction costs, in the year ended March 31, 2023. The purchase price included the assumption of certain liabilities of the Company; no cash proceeds were received in the transaction. The operating results of the Stuart, Florida, manufacturing operations are included within the Interiors (formerly Aerospace Structures) reportable segment through the date of divestiture.

In the year ended March 31, 2023, the Company recognized a gain of approximately $4,500 from working capital settlements related to the fiscal 2022 divestitures described below.

Fiscal 2022 Divestitures

In May 2020, the Company’s Board of Directors committed to a plan to sell its composites manufacturing operations located in Milledgeville, Georgia and Rayong, Thailand. In August 2020, the Company entered into a definitive agreement with the buyer of the composites manufacturing operations in Georgia and Thailand. In February 2021, the Company entered into a definitive agreement to sell its large structure manufacturing operations in Red Oak, Texas, to the same buyer of the Milledgeville and Rayong composites manufacturing operations. In the year ended March 31, 2021, the Company adjusted the carrying amount of these assets held for sale to its estimated fair value less cost to sell and recognized a loss in that period of approximately $102,500, which is included in (gain) loss on sale of assets and businesses. The estimate of fair value is categorized as Level 2 within the fair value hierarchy. The key assumptions used in the estimate of fair value were the negotiated sales price of the assets and the assumption of the disposal group’s liabilities. These transactions closed in May 2021. Upon the completion of the sale of the composites and large structure manufacturing operations, the Company received proceeds of approximately $155,000 net of the purchase of a facility related to the divestiture and other transaction costs and recognized an additional loss of approximately $6,000, which is presented on the accompanying condensed consolidated statements of operations within (gain) loss on sale of assets and businesses for the year ended March 31, 2022. The loss was primarily the result of changes in the working capital balances of the disposal group from March 31, 2021, to the date of divestiture. The operating results of these related operations are included within the Interiors (formerly Aerospace Structures) reportable segment through the date of divestiture. As disclosed in Note 15, as a result of the completed sale of these manufacturing operations, the Company recognized a curtailment loss of approximately $16,000 during the three months ended June 30, 2021.

In August 2021, the Company’s Board of Directors committed to a plan to sell and license certain legacy product lines of the Company’s Staverton, United Kingdom operations. The transaction includes the existing facility and select product lines associated with the site. The transaction closed in October 2021 for net proceeds of approximately $34,000, and the effect on earnings was insignificant. The operating results of the Staverton, United Kingdom, manufacturing operations were included within the Systems & Support reportable segment through the date of divestiture.

As a result of the fiscal 2022 divestitures described above, including routine closing working capital adjustments, the Company recognized losses of approximately $8,000 in the three months ended September 30, 2021.

Fiscal 2021 Divestitures

In August 2020, the Company completed the transfer of the assets and certain liabilities associated with its Gulfstream G650 wing supply chain activities for cash proceeds net of transaction costs of approximately $51,000. This transaction also resulted in the derecognition of approximately $18,157 in accrued warranties related to these activities. The Company recognized a loss of approximately $819, which is presented on the accompanying consolidated statements of operations within (gain) loss on sale of assets and businesses. The operating results associated with the G650 wing supply chain activities were included within Interiors (formerly Aerospace Structures) through the date of transfer.

Contract Assets and Liabilities

Contract assets primarily represent revenues recognized for performance obligations that have been satisfied or partially satisfied but for which amounts have not been billed. This typically occurs when revenue is recognized over time but the Company's contractual right to bill the customer and receive payment is conditional upon the satisfaction of additional performance obligations in the contract, such as final delivery of the product. Contract assets are typically derecognized when billed in accordance with the terms of the contract. The Company pools contract assets that share underlying risk characteristics and records an allowance for expected credit losses based on a combination of prior experience, current economic conditions and management’s expectations of future economic conditions, and specific matters when they arise. Contract assets are presented net of this reserve on the accompanying consolidated balance sheets. For the years ended March 31, 2023 and 2022, credit loss expense and write-offs related to contract assets were immaterial.

Contract liabilities are recorded when customers remit contractual cash payments in advance of the Company satisfying performance obligations under contractual arrangements, including those with performance obligations to be satisfied over a period of time. Contract liabilities other than those pertaining to forward loss reserves are derecognized when or as revenue is recognized.

Contract modifications can also impact contract asset and liability balances. When contracts are modified to account for changes in contract specifications and requirements, the Company considers whether the modification either creates new or changes the existing enforceable rights and obligations. Contract modifications that are for goods or services that are not distinct from the existing contract, due to the significant integration with the original good or service provided, are accounted for as if they were part of that existing contract. The effect of a contract modification to an existing contract on the transaction price and the Company’s measure of progress for the performance obligation to which it relates, is recognized as an adjustment to revenue (either as an increase in or a reduction of revenue) on a cumulative catch-up basis. When the modifications include additional performance obligations that are distinct and at relative stand-alone selling price, they are accounted for as a new contract and performance obligation, which are recognized prospectively.

Contract balances are classified as assets or liabilities on a contract-by-contract basis at the end of each reporting period. The following table summarizes the Company’s contract assets and liabilities balances:

	March 31, 2023			March 31, 2022			Change
Contract assets	$	103,027		$	101,893		$	1,134
Contract liabilities		(44,945	)		(172,862	)		127,917
Net contract asset (liability)	$	58,082		$	(70,969	)	$	129,051

The Company recognized revenue due to changes in estimates associated with performance obligations satisfied or partially satisfied in previous periods of $21,208. The change in contract assets was not significant in the year ended March 31, 2023. The change in contract liabilities is the result of revenue recognized in excess of the receipt of additional customer advances as well as the extinguishment of approximately $103,803 of customer advance repayment obligations that were assumed by the buyer of the Stuart, Florida, manufacturing operations. For the period ended March 31, 2023, the Company recognized $46,779 of revenue that was included in the contract liability balance at the beginning of the period.

Performance Obligations

Customers generally contract with the Company for requirements in a segment relating to a specific program, and the Company’s performance obligations consist of a wide range of engineering design services and manufactured components, as well as spare parts and repairs. A single contract may contain multiple performance obligations consisting of both recurring and nonrecurring elements.

As of March 31, 2023, the Company has the following unsatisfied, or partially unsatisfied, performance obligations that are expected to be recognized in the future as noted in the table below. The Company expects options to be exercised in addition to the amounts presented below.

	Total		Less than 1 year		1-3 years		4-5 years		More than 5 years
Unsatisfied performance obligations	$	1,407,748	$	871,858	$	504,989	$	27,746	$	3,155

Receivables Securitization Program

In connection with the Securitization Facility, the Company sells on a revolving basis certain eligible accounts receivable to Triumph Receivables, LLC, a wholly-owned special-purpose entity, which in turn sells a percentage ownership interest in the receivables to commercial paper conduits sponsored by financial institutions. The Company is the servicer of the trade accounts receivable under the Securitization Facility. Interest rates are based on the Bloomberg Short Term Bank Yield Index (“BSBY”), plus a 2.25% fee on the drawn portion and a fee ranging from 0.45% to 0.50% on the undrawn portion of the Securitization Facility. The drawn fee may be reduced to 2.00% depending on the credit rating of the Company. Collateralized letters of credit incur fees at a rate of 0.125%. The Company secures its trade accounts receivable, which are generally non-interest-bearing, in transactions that are accounted for as borrowings pursuant to ASC 860, Transfers and Servicing. The Company has established a letter of credit facility under the Securitization Facility. Under the provisions of the letter of credit facility, the Company may request the Securitization Facility’s administrator to issue one or more letters of credit that will expire no later than 12 months after the date of issuance, extension or renewal, as applicable.

As of March 31, 2023, the maximum amount available under the Securitization Facility was $100,000. The actual amount available under the Securitization Facility at any point in time is dependent upon the balance of eligible accounts receivable as well as the amount of letters of credit outstanding.

At March 31, 2023 and 2022, there were $0 in borrowings and $19,753 and $23,339, respectively, in letters of credit outstanding under the Securitization Facility, primarily to support insurance policies. The Securitization Facility expires in November 2024.

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

Senior Secured First Lien Notes due 2028

On March 14, 2023, the Company issued $1,200,000 principal amount of 9.000% Senior Secured First Lien Notes due March 15, 2028, pursuant to an indenture among the Company, the Guarantor Subsidiaries, and U.S. Bank National Association, as trustee. The 2028 First Lien Notes were sold at 100% of the principal amount and have an effective interest yield of 9.000%. Interest is payable semi-annually in cash in arrears on March 15 and September 15 of each year, commencing on September 15, 2023. In connection with the issuance of the 2028 First Lien Notes, the Company incurred approximately $20,000 of costs, which were deferred and are being amortized over the term of the 2028 First Lien Notes.

The 2028 First Lien Notes and the guarantees are first lien secured obligations of the Company and the Guarantor Subsidiaries. The 2028 First Lien Notes:

(i)rank equally in right of payment to any existing and future senior indebtedness of the Company and Guarantor Subsidiaries, including the 2025 Notes (as defined below);

(ii)are effectively senior to all existing and future second lien obligations and all existing and future unsecured indebtedness of the Company and the Guarantor Subsidiaries, but only to the extent of the value of the Collateral (as defined below), and after giving effect to any permitted additional first lien secured obligations and other permitted liens of senior or equal priority);

(iii)are senior in right of payment to all future subordinated indebtedness of the Company and the Guarantor Subsidiaries;

(iv)are secured by the Collateral on a pari passu basis with any future permitted additional first lien secured obligations, subject to the Collateral Trust Agreement;

(v)are effectively subordinated to any existing and future obligations of the Company and the Guarantor Subsidiaries that are secured by assets that do not constitute the Collateral, in each case, to the extent of the value of the assets securing such obligations; and

(vi)are structurally subordinated to all existing and future indebtedness and other liabilities of the Company’s existing and future subsidiaries that do not guarantee the 2028 First Lien Notes, including the Securitization Facility.

The 2028 First Lien Notes are guaranteed on a full, senior, joint and several basis by each of the Company’s domestic restricted subsidiaries (the “Guarantor Subsidiaries”) that guarantees the 2025 Notes. In the future, each of the Company’s domestic restricted subsidiaries (other than any domestic restricted subsidiary that is a receivable subsidiary) that (1) is not an immaterial subsidiary, (2) becomes a borrower under any of its material debt facilities or (3) guarantees (a) any of the Company’s indebtedness or (b) any indebtedness of the Company’s domestic restricted subsidiaries, in the case of either (a) or (b), incurred under any of the Company’s material debt facilities, will guarantee the 2028 First Lien Notes. Under certain circumstances, the guarantees may be released without action by, or consent of, the holder of the 2028 First Lien Notes.

The 2028 First Lien Notes and the guarantees are secured, subject to permitted liens, by first-priority liens on substantially all of the Company’s and the Guarantor Subsidiaries’ assets (including certain of the Company’s real estate assets), whether now owned or hereafter acquired, other than certain excluded property, which liens will secure permitted additional first lien obligations on a pari passu basis, subject to the Collateral Trust Agreement (the “Collateral”). Under certain circumstances, the Collateral may be released without action by, or the consent of, the holders of the 2028 First Lien Notes. The 2028 First Lien Notes and the guarantees will not be secured by the assets of Non-Guarantor Subsidiaries (as defined below), which include the unrestricted subsidiaries to whom certain of the Company’s accounts receivables are and may in the future be sold to support borrowing under the Receivables Securitization Facility.

A collateral trust agreement (the “Collateral Trust Agreement”) among the Company, the Guarantor Subsidiaries, the Collateral Trustee and U.S. Bank National Association, in its capacity as the trustee for the 2028 First Lien Notes, will set forth therein the relative rights with respect to the Collateral as among the trustee for the 2028 First Lien Notes and certain subsequent holders of

(Dollars in thousands, except per share data)

first lien obligations and covering certain other matters relating to the administration of security interests. The Collateral Trust Agreement will generally control substantially all matters related to the Collateral, including with respect to decisions, distribution of proceeds or enforcement. Pursuant to the Collateral Trust Agreement, on the issue date of the 2028 First Lien Notes the Collateral Trustee will control certain matters related to the Collateral that the Collateral Trust Agreement specifies are in its discretion. If the Company incurs certain types of additional first lien obligations, the Controlling First Lien Holders (as defined in the Collateral Trust Agreement) will have the right to control decisions relating to the Collateral that are outside the Collateral Trustee’s discretion under the Collateral Trust Agreement and the 2028 Note holders may no longer be in control of such decisions.

The Company may redeem the 2028 First Lien Notes, in whole or in part, at any time or from time to time on or after March 15, 2025, at specified redemption prices, plus accrued and unpaid interest, if any, to the redemption date. At any time or from time to time prior to March 15, 2025, the Company may redeem the 2028 First Lien Notes, in whole or in part, at a redemption price equal to 100% of their principal amount plus a make whole premium, together with accrued and unpaid interest, if any, to the redemption date. In addition, the Company may redeem up to 40% of the aggregate principal amount of the outstanding 2028 First Lien Notes prior to March 15, 2025, with the net cash proceeds from certain equity offerings at a redemption price equal to 109.000% of their principal amount, together with accrued and unpaid interest, if any, to the redemption date. The Company may redeem, at any time from time to time before March 15, 2025, up to 10% of the aggregate principal amount of the notes per annum, at a redemption price equal to 103% of the aggregate principal amount plus accrued and unpaid interest, if any, to the redemption date.

If the Company experiences specific kinds of changes of control, the Company is required to offer to purchase all of the 2028 First Lien Notes at a purchase price of 101% of their principal amount, plus accrued and unpaid interest, if any, to the date of purchase.

The 2028 First Lien Notes Indenture contains covenants that, among other things, limit the ability of the Company and its restricted subsidiaries to: (i) incur additional indebtedness; (ii) pay dividends or make other distributions; (iii) make other restricted payments and investments; (iv) create liens; (v) incur restrictions on the ability of restricted subsidiaries to pay dividends or make certain other payments; (vi) sell assets, including capital stock of restricted subsidiaries; (vii) enter into sale and leaseback transactions; (viii) merge or consolidate with other entities; and (ix) enter into transactions with affiliates. In addition, the 2028 First Lien Notes Indenture requires, among other things, the Company to provide financial and current reports to holders of the 2028 First Lien Notes or file such reports electronically with the SEC. These covenants are subject to a number of exceptions, limitations and qualifications set forth in the Indenture, as well as suspension periods in certain circumstances.

The Company follows ASC 740, Income Taxes, which prescribes a recognition threshold and measurement attribute criteria for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return, as well as guidance on derecognition, classification, interest and penalties, disclosure and transition. The Company's policy is to release the tax effects from accumulated other comprehensive loss when all of the related assets or liabilities that gave rise to the accumulated other comprehensive loss (income) have been derecognized. The Company has elected to treat global intangible low-taxed income (“GILTI”) as a period expense.

A valuation allowance, if needed, reduces deferred tax assets to the amount expected to be realized. When determining the amount of net deferred tax assets that are more likely than not to be realized, the Company assesses all available positive and negative evidence. This evidence includes, but is not limited to, prior earnings history, expected future earnings, carry-back and carry-forward periods and the feasibility of ongoing tax strategies that could potentially enhance the likelihood of the realization of a deferred tax asset. The weight given to the positive and negative evidence is commensurate with the extent the evidence may be objectively verified. As such, it is generally difficult for positive evidence regarding projected future taxable income exclusive of reversing taxable temporary differences to outweigh objective negative evidence of recent financial reporting losses.

Based on these criteria and the relative weighting of both the positive and negative evidence available and, in particular, the activity surrounding the Company's prior earnings history, including the forward losses and intangible impairments previously recognized, management determined that it was necessary to establish a valuation allowance against principally all of its net deferred tax assets. Given the objective verifiable negative evidence of a three-year cumulative loss and the weighting of all available positive evidence, the Company excluded projected taxable income (aside from reversing taxable temporary differences) from the assessment of income that could be used as a source of taxable income to realize the deferred tax assets.

During fiscal year 2023, the Company adjusted the valuation allowance against the consolidated net deferred tax asset by $222 primarily due to an aggregate utilization of net operating loss carryforwards of approximately $146,354, utilization of capital loss carryforwards, and changes to temporary differences related to the impairment of long-lived intangible assets, interest disallowance, research and development cost amortization, and pension and other postretirement benefit plans. As of March 31, 2023, management determined that it was necessary to maintain a valuation allowance against principally all of its net deferred tax assets.

As of March 31, 2023, the Company has net operating loss carryforwards of $526,498, $1,433,276, and $136,646 for U.S. federal, state, and foreign jurisdictions, respectively. Approximately $65,020 of U.S. federal net operating losses begin to expire in 2038, and $461,478 have an indefinite carryforward period. State net operating losses begin to expire in 2024, with an immaterial portion classified as indefinite. Approximately $6,357 of foreign net operating losses begin to expire in 2027, and $130,289 have an indefinite carryforward period.

The effective income tax rate for the fiscal year ended March 31, 2023, was 6.4% as compared with (13.5)% for the fiscal year ended March 31, 2022. The effective income tax rate for the fiscal year ended March 31, 2023, included the benefit of the R&D tax credit of $2,234, and the change in the valuation allowance of $18,243. Due to the prior year pretax loss, the effective tax rate drivers on a percentage basis are amplified. Accordingly, a year-over-year comparison of the effective tax rate may not be indicative of changes in the Company's tax position.

The Company has been granted income tax holiday as an incentive to attract foreign investment by the Government of Thailand. The tax holidays continue to expire in various years through 2026. The Company does not have any other tax holidays in the jurisdictions in which it operates. The income tax benefit attributable to the tax status of our subsidiaries in Thailand was approximately $583 or $0.01 per diluted share in fiscal 2023, $415 or $0.01 per diluted share in fiscal 2022 and $0 or $0.00 per diluted share in fiscal 2021.

At March 31, 2023, cumulative undistributed earnings of foreign subsidiaries, for which no U.S. income or foreign withholding taxes have been recorded is $203,893. As the Company currently intends to indefinitely reinvest all such earnings, no provision has been made for income taxes that may become payable upon distribution of such earnings, and it is not practicable to determine the amount of the related unrecognized deferred income tax liability.

The Company has classified uncertain tax positions as noncurrent income tax liabilities unless expected to be paid in one year.

As of March 31, 2023 and 2022, the total amount of unrecognized tax benefits was $12,085 and $11,800, respectively, all of which would impact the effective rate, if recognized. The Company anticipates that total unrecognized tax benefits may be reduced by zero in the next 12 months. With a few exceptions, the Company is no longer subject to U.S. federal, state, or local income tax examinations, or foreign income tax examinations by tax authorities, for fiscal years ended before March 31, 2014.

13. STOCKHOLDERS' DEFICIT

In March 2022, the Company adopted a tax benefits preservation plan (the " Plan") designed to preserve Triumph’s ability to utilize its net operating loss carryforwards and other tax attributes (collectively, "Tax Benefits"). The Plan replaces a similar plan that was adopted in March 2019 and which expired in March 2022. The Company obtained stockholder approval for the Plan at its annual meeting of stockholders in July 2022.

Under the Plan, Triumph declared a dividend distribution of one right (a “Right”) for each share of its common stock outstanding at the close of business on March 21, 2022. The Plan will expire on March 13, 2025. The Rights also will expire: (i) if the Rights are redeemed or exchanged as provided in the Plan; (ii) if the Board determines that the Plan is no longer necessary or desirable for the preservation of the Tax Benefits; or (iii) if the Board determines that no Tax Benefits, once realized, as applicable, may be carried forward (in which case, the Rights will expire on the first date of the relevant taxable year for which such determination is made).

Pursuant to the Plan, if a stockholder (or group) becomes a 4.9% stockholder without meeting certain customary exceptions, the Rights become exercisable and entitle stockholders (other than the 4.9% stockholder or group causing the rights to become exercisable) to purchase additional shares of Triumph at a significant discount, resulting in significant dilution in the economic interest and voting power of the 4.9% stockholder or group causing the Rights to become exercisable. Stockholders owning 4.9% or more of Triumph’s outstanding shares at the time the Plan was adopted were grandfathered and will only cause the Rights to distribute and become exercisable if they acquire an additional one percent or more of Triumph’s outstanding shares. Under the Plan, the Board has the ability to determine in its sole discretion that any person shall not be deemed an acquiring person and therefore that the Rights shall not become exercisable if such person becomes a 4.9% stockholder. The adoption of the Plan and the dividend distribution did not have an impact on the Company’s consolidated financial statements.

On February 4, 2021, the Company implemented an “at the market” stock issuance program by entering into an Equity Distribution Agreement (the “Equity Distribution Agreement”) with Citigroup Global Markets Inc. (the “Manager”). Under the terms of the Equity Distribution Agreement, the Company may from time to time to or through the Manager, acting as agent and/or principal, offer and sell shares of its common stock having a gross sales price of up to $150,000. From the date the program was implemented through March 31, 2021, the Company completed the program, selling 9,178,752 shares with a gross sales price of $150,000 for total proceeds net of stock issuance costs of $145,383.

In 2014, the Company's Board of Directors authorized an increase in the Company's existing stock repurchase program by up to 5,000,000 shares of its common stock in addition to the 500,800 shares authorized under prior authorizations. As of March 31, 2023, the Company remains able to purchase an additional 2,277,789 shares. Repurchases may be made from time to time in open market transactions, block purchases, privately negotiated transactions or otherwise at prevailing prices. No time limit has been set for completion of the program.

The holders of the common stock are entitled to one vote per share on all matters to be voted upon by the stockholders of Triumph.

The Company has preferred stock of $0.01 par value, 250,000 shares authorized. At March 31, 2023 and 2022, zero shares of preferred stock were outstanding.

14. EARNINGS (LOSS) PER SHARE

The calculation of basic earnings (loss) per share is based on the weighted average number of common shares considered outstanding during the periods. The calculation of diluted earnings per share reflects the effect of all potentially dilutive securities (principally outstanding warrants and outstanding restricted stock units). As disclosed in Note 2, the warrants permit the tendering of Designated Notes in payment of the exercise price. In computing diluted EPS, the Company applies the if-converted method to the warrants and such warrants are assumed to be exercised and the Designated Notes are assumed to be tendered unless tendering cash would be more advantageous to the warrant holder. Interest (net of tax) on any Designated Notes assumed to be tendered is added back as an adjustment to the numerator. The numerator also is adjusted for any nondiscretionary adjustments based on income (net of tax) including, for example, warrant remeasurement gains and losses recognized in the period. If cash exercise is more advantageous, the Company applies the treasury stock method to the warrants when calculating diluted EPS.

The following is a reconciliation between the weighted average common shares outstanding used in the calculation of basic and diluted earnings (loss) per share:

15. EMPLOYEE BENEFIT PLANS

Defined Contribution Pension Plan

The Company sponsors a defined contribution 401(k) plan, under which salaried and certain hourly employees may defer a portion of their compensation. Eligible participants may contribute to the plan up to the allowable amount as determined by the plan of their regular compensation before taxes. The Company generally matches contributions at a rate of 75% of the first 6% of compensation contributed by the participant. All contributions and Company matched contributions are invested at the direction of the employee in one or more investment options offered under the plan. Company matching contributions vest immediately and aggregated to $9,329, $2,998, and $1,665 for the fiscal years ended March 31, 2023, 2022, and 2021, respectively. Effective April 1, 2020, the Company suspended its 401(k) matching contribution for non-represented employees and some represented employees. This suspension was ended December 31, 2021, and the Company's 401(k) matching program recommenced effective January 1, 2022.

Defined Benefit Pension and Other Postretirement Benefit Plans

The Company sponsors several defined benefit pension plans covering some of its employees. Most current employees are ineligible to participate in the plans or have ceased to accrue additional benefits under the plans. Benefits under the defined benefit plans are based on years of service and, for most non-represented employees, on average compensation for certain years. It is the Company's policy to fund at least the minimum amount required for all qualified plans, using actuarial cost methods and assumptions acceptable under applicable government regulations, by making payments into a trust separate from us. The Company has in the past contributed and may in the future contribute shares of its common stock to this separate trust which would reduce the cash contribution required by the Company.

In addition to the defined benefit pension plans, the Company provides other postretirement benefits ("OPEB") in the form of certain health care benefits for eligible retired employees. Such benefits are unfunded as of March 31, 2023. The right to benefits under the current program ceased for all represented participants (actively employed and retired) by April 1, 2020. Company-funded notional health reimbursement accounts were provided to retired participants (and their dependents) whose eligibility for current benefits ended under the new agreement. As a result, the Company's OPEB liability is no longer material. Actuarial gains associated with the OPEB plan are carried within AOCI as shown in the table below.

In accordance with ASC 715, the Company has recognized the funded status of the benefit obligation as of March 31, 2023 and 2022, on the accompanying consolidated balance sheets. The funded status is measured as the difference between the fair value of the plans' assets and the PBO or accumulated postretirement benefit obligation of the plan. The plan assets are principally publicly traded investments which were valued based on the market price as of the measurement date. Investments that are not publicly traded were valued based on the estimated fair value of those investments based on the Company’s evaluation of data from fund managers and comparable market data.

The following tables set forth the Company's consolidated defined benefit pension plans for its union and non-union employees as of March 31, 2023 and 2022, and the amounts recorded on the consolidated balance sheets at March 31, 2023 and 2022. Company contributions include amounts contributed directly to plan assets and indirectly as benefits paid from the Company's assets. Benefit payments reflect the total benefits paid from the plans and the Company's assets. Information on the plans includes both the domestic qualified and nonqualified plans and the foreign qualified plans.

The discount rate is determined annually as of each measurement date, based on a review of yield rates associated with long-term, high-quality corporate bonds. At the end of each year, the discount rate is primarily determined using the results of bond yield curve models based on a portfolio of high-quality bonds matching notional cash inflows with the expected benefit payments for each significant benefit plan.

The expected return on plan assets is determined based on a market-related value of assets ("MRVA"), which is a smoothed asset value. For fixed income securities, the MRVA is determined using the fair value of the fixed income assets. For all other classes of pension assets, the MRVA is calculated by recognizing investment performance that is different from that expected on a straight-line basis over five years. Actuarial gains and losses are amortized over the average remaining life expectancy of inactive participants for plans that are predominantly inactive and over the expected future service for active participants for other plans, but only to the extent unrecognized gains or losses exceed a corridor equal to 10% of the greater of the projected benefit obligation or market-related value of assets.

The Company estimates the service and interest cost of its pension and OPEB plans by using the specific spot rates derived from the yield curve used to discount the cash flows reflected in the measurement of the benefit obligation. The Company believes this approach provides a precise measurement of service and interest costs due to the correlation between projected benefit cash flows to the corresponding spot yield curve rates.

During the fiscal year ended March 31, 2023, the Society of Actuaries did not release a new mortality projection scale, and therefore the mortality projection scale remains unchanged. The Company did reflect an adjustment to the base mortality table for a subset of participants based on its review of actual mortality experience in the measurement of its U.S. pension plan as of March 31, 2023. This change resulted in an increase in the benefit obligation.

The projected benefit obligation assumptions impacting net actuarial gain consist of changes in discount and mortality rates, as well as changes in plan experience.

The Company periodically experiences events or makes changes to its benefit plans that result in curtailment or special charges. Curtailments are recognized when events occur that significantly reduce the expected years of future service of present employees or eliminates the benefits for a significant number of employees for some or all of their future service.

Curtailment losses are recognized when it is probable the curtailment will occur and the effects are reasonably estimable. Curtailment gains are recognized when the related employees are terminated or a plan amendment is adopted, whichever is applicable.

As required under ASC 715, the Company remeasures plan assets and obligations during an interim period whenever a significant event occurs that results in a material change in the net periodic pension cost. The determination of significance is based on judgment and consideration of events and circumstances impacting the pension costs.

The following summarizes the key events whose effects on net periodic benefit cost and obligations are included in the tables above:

•On March 21, 2022, the Company elected to purchase annuities and settle the pension obligations for approximately 2,500 retired participants in its qualified U.S. pension plan. As a result of this transaction approximately $52,256 of plan assets and $51,418 of plan liabilities were transferred to the Nationwide Life and Annuity Insurance Company. The settlement resulted in the recognition of prior noncash actuarial losses of approximately $32,116 in the year ended March 31, 2022. The settlement's impact on the accompanying consolidated balance sheets was insignificant as the plan's assets were materially consistent with the settled pension obligation.

•Effective August 31, 2021, the Company settled the fully-funded pension obligation it had retained subsequent to its fiscal year 2019 divestiture of Triumph Geared Solutions - Toronto. The settlement resulted in the recognition of prior noncash actuarial losses of approximately $3,826 in the year ended March 31, 2022. The settlement's impact on the accompanying consolidated balance sheets was insignificant as the plan's assets were materially consistent with the settled pension obligation.

•Upon the completion of the sale of the composites and large structure manufacturing operations as disclosed in Note 3, the expected future service of certain defined benefit pension plan participants was curtailed and certain participants became eligible for subsidized early retirement benefits under the terms of the relevant plan. As a result, the Company performed an interim remeasurement and recognized a onetime pension curtailment charge of approximately $16,024 which is presented in non-service defined benefit income on the accompanying condensed consolidated statement of operations for year ended March 31, 2022.

Additionally, the Company accrued a Withdrawal Liability (as defined below), and recognized in non-serviced defined benefit income, of $14,644 as a result of the exit of its Spokane, Washington, composites manufacturing operations in the year ended March 31, 2023. Refer to Note 17 for further information.

Expected Pension Benefit Payments

The total estimated future benefit payments for the pension plans are expected to be paid from the plan assets and company funds. The OPEB payments reflect the Company's portion of the funding. Estimated future benefit payments from plan assets and Company funds for the next ten years are as follows:

Year	Pension Benefits

Pension plan assets are invested in various asset classes that are expected to produce a sufficient level of diversification and investment return over the long-term. The investment goals are to exceed the assumed actuarial rate of return over the long-term within reasonable and prudent levels of risks and to meet future obligations.

Asset/liability studies are conducted on a regular basis to provide guidance in setting investment goals for the pension portfolio and its asset allocation. The asset allocation aims to prudently achieve a strong, risk-adjusted return while seeking to minimize funding level volatility and improve the funded status of the plans. The pension plans currently employ a liability-driven investment ("LDI") approach, where assets and liabilities move in the same direction. The goal is to limit the volatility of the funding status and cover part, but not all, of the changes in liabilities. Most of the liabilities' changes are due to interest rate movements.

To balance expected risk and return, allocation targets are established and monitored against acceptable ranges. All investment policies and procedures are designed to ensure that the plans' investments are in compliance with the Employee Retirement Income Security Act of 1974 ("ERISA"). Guidelines are established defining permitted investments within each asset class. Each investment manager has contractual guidelines to ensure that investments are made within the parameters of their asset class or in the case of multi-asset class managers, the parameters of their multi-asset class strategy. Certain investments are not permitted at any time, including investment directly in employer securities and uncovered short sales.

Cash equivalents and other short-term investments are primarily held in registered short-term investment vehicles which are valued using a market approach based on quoted market prices of similar instruments.

Public equity securities, including common stock, are primarily valued using a market approach based on the closing fair market prices of identical instruments in the principal market on which they are traded. Commingled funds that are open-ended mutual funds for which the fair value per share is determined and published by the respective mutual fund sponsor and is the basis for current observable transactions are categorized as Level 1 fair value measures.

Investments in commingled funds and private equity and infrastructure funds are carried at net asset value ("NAV") as a practical expedient to estimate fair value. The NAV is the total value of the fund divided by the number of shares outstanding. Adjustments to NAV, if any, are determined based on evaluation of data provided by fund managers, including valuation of the underlying investments derived using inputs such as cost, operating results, discounted future cash flows and market-based comparable data. In accordance with ASC 820-10, investments that are measured at NAV practical expedient are not classified in the fair value hierarchy; however, their fair value amounts are presented in these tables to permit reconciliation of the fair value hierarchy to the total plan assets disclosed in this footnote.

Corporate, government agency bonds and mortgage-backed securities are primarily valued using a market approach with inputs that include broker quotes, benchmark yields, base spreads and reported observable trades for identical or comparable instruments.

Other investments include insurance contracts primarily valued based on estimates of the premium required to acquire similar insurance contracts using market-based comparable data.

The discount rate is determined as of each measurement date, based on a review of yield rates associated with long-term, high-quality corporate bonds. The calculation separately discounts benefit payments using the spot rates from a long-term, high-quality corporate bond yield curve.

The effect of a 25 basis-point change in discount rates as of March 31, 2023, is shown below:

		Pension Benefits
Increase of 25 basis points
Obligation	*	$	(34,222	)
Net periodic expense			176
Decrease of 25 basis points
Obligation	*	$	35,567
Net periodic expense			(204	)

* Excludes impact to plan assets due to the LDI investment approach discussed above under "Plan Assets, Investment Policy and Strategy."

The long-term rate of return assumption represents the expected average rate of earnings on the funds invested to provide for the benefits included in the benefit obligations. The long-term rate of return assumption is determined based on a number of factors, including historical market index returns, the anticipated long-term asset allocation of the plans, historical plan return data, plan expenses and the potential to outperform market index returns. For fiscal 2024, the expected long-term rate of return is 5.75% - 8.00%.

Anticipated Contributions to Defined Benefit

The Company expects to contribute approximately $14,700 to its qualified U.S. defined benefit pension plans during fiscal 2024. No plan assets are expected to be returned to the Company in fiscal 2024.

16. STOCK COMPENSATION PLANS

The Company has stock incentive plans under which employees and non-employee directors may be granted equity awards in the form of stock options with an exercise price equal to the fair value of the Company’s stock on the grant date or in the form of restricted stock or restricted stock units that vest pursuant to service conditions and, in some cases, performance or market conditions. The stock incentive and compensation plans under which outstanding equity awards have been granted to employees, officers, and non-employee directors are the Triumph Group 2018 Equity Plan (the "2018 Plan"), the Triumph Group 2013 Equity and Cash Incentive Plan (the “2013 Plan”), the 2016 Directors’ Equity Compensation Plan, as amended (the “Directors’ Plan”), and the Amended and Restated Directors’ Stock Incentive Plan (the “Prior Directors’ Plan”). The Prior Directors’ Plan expired by its terms during fiscal 2017. The current stock incentive and compensation plans used for future awards are the 2018 Plan and the Directors’ Plan. New grants under the 2013 Plan ceased upon the approval of the 2018 Plan in fiscal 2019, and the 2013 Plan will formally expire by its terms during fiscal 2024. The 2018 Plan and the Directors’ Plan are collectively referred to in this note as the plans.

Management and the compensation committee have utilized restricted stock and restricted stock units as its primary form of share-based incentive compensation. Restricted stock and restricted stock units that vest solely pursuant to service conditions generally vest on a graded basis over a three year period and are subject to forfeiture should the grantee’s employment be terminated prior to an applicable vesting date. Management and the compensation committee have also granted restricted stock and restricted stock units, referred to herein as performance restricted stock awards, that vest pursuant to a combination of service conditions as well as market and performance conditions. Such awards may vest, subject to specific market or performance conditions, on a cliff vesting basis at the end of a three year performance period, on a graded basis over discrete performance periods over three year period, or a combination of thereof. The market and performance conditions may result in the awards vesting below target, including zero vesting awards if certain threshold vesting conditions are not met, or up to 300% of the number of awards granted, if certain vesting conditions are exceeded. The share-based payment expense arising from restricted stock and restricted stock unit expense is included in capital in excess of par value. The fair value of restricted stock or restricted stock units awards subject only to service conditions or service and performance conditions is determined by the product of the number of shares granted and the grant date market price of the Company's common stock, adjusted for material non-public information that the Company may be aware of as of the grant date, if any. The fair value of restricted stock or restricted stock units awards that contain market conditions is determined by the product of the number of shares granted and the grant date fair value of such an award value using a Monte Carlo valuation methodology. The fair value of share-based

(Dollars in thousands, except per share data)

compensation granted to employees was $13,728, $14,129, and $13,103 during the fiscal years ended March 31, 2023, 2022, and 2021, respectively. The fair value of restricted stock and restricted stock unit awards is expensed on a straight-line basis over the requisite service period which is typically the vesting period. The Company recognized $8,913, $9,782 and $12,701 of share-based compensation expense during the fiscal years ended March 31, 2023, 2022, and 2021, respectively. The Company has classified share-based compensation within selling, general and administrative expenses to correspond with the same line item as the majority of the cash compensation paid to the employees receiving share-based compensation.

At March 31, 2023 and 2022, 979,855 shares and 1,706,634 shares of common stock, respectively, were available for issuance under the plans. A summary of the status of the Company's non-vested shares/units of restricted stock and deferred stock units as of March 31, 2023, and changes during the fiscal year ended March 31, 2023, is presented below.

	Shares			Weighted- Average Grant Date Fair Value
Non-vested restricted awards and deferred stock units at March 31, 2022		1,361,155		$	18.00
Granted		954,949			14.38
Vested		(561,862	)		16.46
Forfeited		(241,046	)		19.73
Non-vested restricted awards and deferred stock units at March 31, 2023		1,513,196		$	16.01

The fair value of employee restricted stock and restricted stock units which vested during fiscal 2023, 2022 and 2021 was $9,247, $7,453, and $8,037, respectively. Expected future compensation expense on restricted stock units, net of expected forfeitures, is approximately $11,626, which is expected to be recognized over the remaining weighted average vesting period of approximately 1.5 years.

17. COMMITMENTS AND CONTINGENCIES

Environmental Matters

Certain of the Company's business operations and facilities are subject to a number of federal, state, local and foreign environmental laws and regulations. Former owners generally indemnify the Company for environmental liabilities related to the assets and businesses acquired which existed prior to the acquisition dates. In the opinion of management, there are no significant environmental contingent liabilities which would have a material effect on the financial condition or operating results of the Company which are not covered by such indemnification.

Commercial Disputes and Litigation

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

In the ordinary course of business, the Company is involved in disputes, claims and lawsuits with employees, suppliers and customers, as well as governmental and regulatory inquiries, that it deems to be immaterial. Some may involve claims or potential claims of substantial damages, fines, penalties or injunctive relief. While the Company cannot predict the outcome of any pending or future litigation or proceeding and no assurances can be given, the Company does not believe that any pending matter will have a material effect, individually or in the aggregate, on its financial position or results of operations.

Divestitures, Disposals, Guarantees, and Indemnifications

As disclosed in Note 3, we have engaged in a number of divestitures. In connection with divestitures and related transactions, the Company from time to time has indemnified and has been indemnified by third parties against certain liabilities that may arise in connection with, among other things, business activities prior to the completion of the respective transactions. The term of these indemnifications, which typically pertain to environmental, tax and product liabilities, is generally indefinite. As of March 31, 2023, no indemnification assets or liabilities have been recorded.

As it relates to certain divestitures, disputes have arisen or may continue to arise between the Company and the acquirer subsequent to the completion and closing of the divestiture transaction. Such disputes have included or may include amounts payable to or from the buyer for closing working capital adjustments to the purchase price as well as claims regarding alleged violations of contractual terms, representations, and warranties of the sale agreements, among other matters. The outcome of such disputes typically involve negotiations between the Company and the acquirer, but could also lead to litigation between the parties, and the ultimate claims made by the parties against each other could be material. As of March 31, 2023, we have

74

Triumph Group, Inc.

Notes to Consolidated Financial Statements

(Dollars in thousands, except per share data)

accrued for our estimate of probable losses associated with such disputes, but losses in excess of those currently accrued could be incurred and may be material. The Company has received notification of claims which allege certain bases for indemnification and damages relating to certain divestitures, including a May 17, 2023, letter relating to the sale of the Stuart facility. The relevant agreements generally contain limits on certain damages that may be payable under the relevant agreements. For example, the divestiture agreement relating to the sale of the Stuart facility contains an $18,750 general cap on breaches of representations (other than certain specified representations) and a $25,000 cap on breaches of certain specified representations related to contracts and product warranties, in each case absent certain circumstances, including fraud or breaches of fundamental or tax representations. While the Company cannot predict the outcome of any pending or future litigation, proceeding, or claim and no assurances can be given, the Company intends to vigorously defend claims brought against it and does not believe that any pending matter will have a material effect, individually or in the aggregate, on its financial position or results of operations. If the Company is unable to successfully and equitably resolve such claims and assertions, its business, financial condition, and results of operations could be materially adversely affected.

Additionally, in connection with certain divestitures, the Company has obtained customer consent to assign specified long-term contracts to the acquirer of the divested business by entering into consent-to-assignment agreements among the customer, the acquirer, and the Company. Pursuant to certain of these agreements, the Company remains a co-obligor under the contract pursuant to guarantee agreements with the customer that predate the divestiture transaction. The term of these obligations typically covers a period of 2 to 5 years from the date of divestiture. There is no limitation to the maximum potential future liabilities under these contracts; however, the Company is typically indemnified by acquirers against such losses that may arise from the acquirers’ failure to perform under the assigned contracts. As of March 31, 2023, no related indemnification assets or liabilities or guarantee liabilities have been recorded, and the Company has not been called upon to act as co-obligor under such arrangements through that date. Also, in connection with certain divestitures, the Company has assigned lease facility lease agreements to the acquirers and entered into agreements to act as a co-obligor under the lease agreement in the event of non-performance under the lease by the assignee. The Company is generally indemnified by the assignee or other third party to the transaction. On May 2, 2023, the Company received a letter from a lessor associated with one such transaction to assert the lessor’s rights against the Company as guarantor. The lease payment associated with the lease is approximately $130 per month over a lease term ending December 31, 2031, although the landlord has acknowledged its duty to mitigate damages by re-leasing the property. The Company expects to be fully indemnified for any amounts payable under such guarantee.

As the Company has completed the disposal of certain facilities, it may be exposed to additional costs such as environmental remediation obligations, lease termination costs, or customer or supplier claims which may have a material effect on its financial position or results of operations when such matters arise and a reasonable estimate of the costs can be made. For example, in the year ended March 31, 2023, the Company withdrew from the IAM National Pension Fund (the “Fund), which is a multiemployer pension plan to which the Company previously contributed on behalf of certain of its represented employees. Such withdrawal occurred as part of the Company’s exit of its Spokane, Washington, composites manufacturing operations. In April 2023, the Company received a letter from the Fund confirming the Company’s complete withdrawal from the Fund and indicating that the Company’s portion of the unfunded vested benefits (the “Withdrawal Liability”) was estimated to be approximately $14,644, payable in quarterly installments of approximately $400 over a period of approximately thirteen years. The Withdrawal Liability is subject to further adjustment based on the finalization of the Fund’s actuarial valuation for the plan year ending December 31, 2021, (i.e., the applicable plan year preceding the date of the Company’s withdrawal). The Company has accrued a liability of $14,644, on the accompanying consolidated balance sheet as of March 31, 2023, representing its estimate of the obligation based on the letter received from the Fund. The Company is in the process of reviewing and responding to the withdrawal liability assessment, and it is possible the Withdrawal Liability could be reduced during that process.

18. CUSTOMER CONCENTRATION

Trade and other receivables from The Boeing Company ("Boeing") represented approximately 12% and 17% of total trade and other receivables as of March 31, 2023 and 2022, respectively. Trade and other receivables from Daher Aerospace Inc. ("Daher") include receivables that largely correspond with payables associated with transition services and represented approximately 20% as of March 31, 2023. The Company has a right to collect such receivables from Daher when the related trade payable is paid by the Company. The transition services agreement with Daher is set to contractually expire on June 30, 2023. Trade and other accounts receivable from Daher were not significant as of March 31, 2022. The Company had no other significant concentrations of credit risk.

Sales to Boeing for fiscal 2023 were $296,132, or 21% of net sales, of which $191,193 and $104,939 were from Systems & Support and Interiors (formerly Aerospace Structures), respectively. Sales to Boeing for fiscal 2022 were $491,606, or 34% of net sales, of which $157,686 and $333,920 were from Systems & Support and Interiors (formerly Aerospace Structures), respectively.

75

Triumph Group, Inc.

(Dollars in thousands, except per share data)

Sales to Boeing for fiscal 2021 were $698,372, or 37% of net sales, of which $225,027 and $473,346 were from Systems & Support and Interiors (formerly Aerospace Structures), respectively.

No other single customer accounted for more than 10% of the Company's net sales; however, the loss of any significant customer, including Boeing, could have a material adverse effect on the Company and its operating subsidiaries.

The Company currently generates a majority of its revenue from clients in the commercial aerospace industry and the military. The Company's growth and financial results are largely dependent on continued demand for its products and services from clients in these industries. When these industries experience a downturn, it is possible that customers in these sectors may conduct less business with the Company.

19. COLLECTIVE BARGAINING AGREEMENTS

Approximately 9% of the Company's labor force is covered under collective bargaining agreements. As of March 31, 2023, none of the Company's collectively bargained workforce is working under contracts that have expired, and 33% of the Company’s collectively bargained workforce are working under contracts that are set to expire within one year.

During the fiscal year ending March 31, 2023, an extension to our current collective bargaining agreement was negotiated and ratified for the Forest, Ohio location. In addition, the Company negotiated and ratified a new collective bargaining agreement for our North Wales, Pennsylvania, location.

20. SEGMENTS

The Company reports financial performance based on the following two reportable segments: Systems & Support and Interiors (formerly Aerospace Structures). The Company’s reportable segments are aligned with how the business is managed, and the Company's views of the markets it serves. The Chief Operating Decision Maker (the "CODM") evaluates performance and allocates resources based upon review of segment information. The CODM utilizes earnings before interest, income taxes, consideration payable to customer related to divestiture, depreciation and amortization, and pension (“Adjusted EBITDAP”) as a primary measure of segment profitability to evaluate the performance of its segments and allocate resources.

Segment Adjusted EBITDAP is total segment revenue reduced by operating expenses (less depreciation and amortization) identifiable with that segment. Corporate includes general corporate administrative costs and any other costs not identifiable with one of the Company’s segments.

The Company does not accumulate net sales information by product or service or groups of similar products and services, and therefore the Company does not disclose net sales by product or service because to do so would be impracticable.

Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our Exchange Act reports is recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms, and that such information is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management necessarily was required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

As of March 31, 2023, we completed an evaluation, under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, of the effectiveness of the design and operation of our disclosure controls and procedures. Based on the foregoing, our principal executive officer and principal financial officer concluded that our disclosure controls and procedures were effective at the reasonable assurance level as of March 31, 2023.

MANAGEMENT'S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

The management of Triumph Group, Inc. ("Triumph") is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934. Triumph's internal control system over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with U.S. generally accepted accounting principles. The Company's internal control over financial reporting includes those policies and procedures that:

(i)pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company;

(ii)provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with U.S. generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and

(iii)provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the company's assets that could have a material effect on the financial statements.

Because of inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation. Also, projections of any evaluation of effectiveness to future periods are subject to risk that controls may become inadequate because of changes in condition, or that the degree of compliance with the policies or procedures may deteriorate.

Triumph's management assessed the effectiveness of Triumph's internal control over financial reporting as of March 31, 2023. In making this assessment, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) ("COSO") in Internal Control—Integrated Framework. Based on management's assessment and those criteria, management believes that Triumph maintained effective internal control over financial reporting as of March 31, 2023.

Triumph's independent registered public accounting firm, Ernst & Young LLP, has audited Triumph's effectiveness of internal control over financial reporting. This report appears on the following page.

Report of Independent Registered Public Accounting Firm

To the Stockholders and Board of Directors of Triumph Group, Inc.

Opinion on Internal Control Over Financial Reporting

We have audited Triumph Group, Inc.’s internal control over financial reporting as of March 31, 2023, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, Triumph Group, Inc. (the Company) maintained, in all material respects, effective internal control over financial reporting as of March 31, 2023, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of Triumph Group, Inc. as of March 31, 2023 and 2022, the related consolidated statements of operations, comprehensive (loss) income, stockholders’ deficit and cash flows for each of the three years in the period ended March 31, 2023, and the related notes and financial statement schedule listed in the Index at Item 15(a) and our report dated May 23, 2023, expressed an unqualified opinion thereon.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.

Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control Over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Changes in Internal Control Over Financial Reporting

In addition to management's evaluation of disclosure controls and procedures as discussed above, we continue to review and enhance our policies and procedures for internal control over financial reporting.

We have developed and implemented a formal set of internal controls and procedures for financial reporting in accordance with the SEC's rules regarding management's report on internal controls. As a result of continued review and testing by management and by our internal and independent auditors, or as a result of newly adopted accounting standards, additional changes may be made to our internal controls and procedures. However, we did not make any changes to our internal control over financial reporting in the fourth quarter of fiscal 2023 that has materially affected or is reasonably likely to materially affect our internal control over financial reporting.

For FY’23 your eligibility will be pro-rated based on the number of eligible days worked in the Fiscal Year. The actual amount of your annual bonus each year will be determined by the Compensation and Management Development Committee (the "Committee") of the Board of Directors of TGI on the basis of the achievement of pre-established performance goals relating to corporate and individual performance.

Restrictive Covenants

a)Disclosure of Confidential Information:

You shall not at any time during your employment with TGI or thereafter, except as properly required in the course of your employment, use, publish, disclose or authorize anyone else to use, publish or disclose any Confidential Information belonging or relating to TGI or any of its affiliates. Confidential Information includes, but is not limited to, models, drawings, blueprints, memoranda and other materials, documents or records of a proprietary nature; information relating to research, manufacturing processes, bills of material, finance, accounting, sales, personnel management and operations; and information particularly relating to customer lists, price lists, customer service requirements, costs of providing service and equipment, pricing and equipment maintenance costs.

b)Patents, Copyrights and Trade Secrets:

You will disclose, and hereby assign, to TGI any and all material of a proprietary nature, particularly including, but not limited to, material subject to protection as trade secrets or as patentable or copyrightable ideas which you may conceive, invent, or discover during the course of your employment with TGI which relate to the business of TGI, or were developed using TGI's resources (collectively, the "Inventions"), and you shall execute and deliver all papers, including applications for patents and do such other acts (entirely at TGI's expense) as may be necessary for TGI to obtain and maintain proprietary rights in any and all countries and to vest title to such Inventions in TGI.

c)Noncompetition and Nonsolicitation:

While you are employed by TGI and its affiliates and for the one-year period following the termination of such employment for any reason (together, the "Restricted Period"), you shall not, in any jurisdiction in which TGI or any of its affiliates is doing business, directly or indirectly, own, manage, operate, control, consult with, be employed by, participate in the ownership, management, operation or control of, or otherwise render services to or engage in, any business engaged in by TGI and its affiliates; provided, that your ownership of securities constituting 2% or less of any publicly traded class of securities of a public company shall not violate this paragraph. During the Restricted Period, you shall not solicit for business or accept the business of, any person or entity who is, or was at any time within the previous 12 months, a customer or client of the business conducted by TGI or its affiliates (or potential customer or client with whom TGI or its affiliates had initiated contact). During the Restricted Period, you shall not, directly or indirectly, employ, solicit for employment, or otherwise contract for or hire, the services of any individual who is then an employee of TGI and its affiliates or who was an employee of TGI and its affiliates within the previous 12 months. Further, during the Restricted Period, you shall not take any action that could reasonably be expected to have the effect of inducing any individual who is then an employee, representative, officer or director of TGI or any of its affiliates, or who was an employee, representative, officer or director of TGI and its affiliates within the previous 12 months, to cease his or her relationship with TGI or any of its affiliates for any reason.

d)Acknowledgements and Remedies:

i.The parties hereto agree that the provisions of clauses a), b), and c) of this Annex A (the "Covenants") have been specifically negotiated by sophisticated commercial parties and agree that all such provisions are reasonable under the circumstances of the activities contemplated by this letter agreement. You acknowledge and agree that the Covenants are reasonable in light of all of the circumstances, are sufficiently limited to protect the legitimate interests of TGI and its affiliates, impose no undue hardship on you, and are not injurious to the public. The parties hereto further agree that your services are of a personal, special and unique character and cannot

Page 3 of NUMPAGES 4

be replaced by TGI, and that the violation by you of any of the Covenants would cause TGI irreparable harm, which could not be adequately compensated by money damages, and that if TGI elects to prevent you from breaching such provisions by obtaining an injunction against you, there is a reasonable probability of TGI's eventual success on the merits. Accordingly, you consent and agree that if you commit any such breach or threaten to commit any breach, in addition to any other remedies as may be available to TGI for such breach, including the recovery of money damages, TGI shall be entitled (without the necessity of showing economic loss or other actual damage) to (A) cease payment of the severance payments and benefits and/or to recoup from you the portion of such severance payments and benefits already paid and (B) temporary and permanent injunctive relief from a court of competent jurisdiction, without posting any bond or other security and without the necessity of proof of actual damage. Furthermore, if TGI institutes any action or proceeding to enforce any of the provisions of this Annex A, to the extent permitted by applicable law, you hereby waive the claim or defense that TGI has an adequate remedy at law, and you shall not assert in any such action or proceeding the defense that any such remedy exists at law.

ii.Prior to execution of this letter agreement, you were advised by TGI of your right to seek independent advice from an attorney of your own selection regarding this letter agreement. You acknowledge that you have entered into this letter agreement knowingly and voluntarily and with full knowledge and understanding of the provisions of this letter agreement after being given the opportunity to consult with counsel. You further represent that, in entering into this letter agreement, you are not relying on any statements or representations made by any of TGI's directors, officers, employees or agents that are not expressly set forth herein, and that you are relying only upon your own judgment and any advice provided by your attorney.

iii.In light of the acknowledgements contained in this clause d), you agree not to challenge or contest the reasonableness, validity or enforceability of any limitations and obligations contained in this letter agreement. In the event that the Covenants shall be determined by any court of competent jurisdiction to be unenforceable by reason of their extending for too great a period of time or over too great a geographical area or by reason of their being too extensive in any other respect, they shall be interpreted to extend only over the maximum period of time for which they may be enforceable and/or over the maximum geographical area as to which they may be enforceable and/or to the maximum extent in all other respects as to which they may be enforceable, all as determined by such court.

Background and Basis of Presentation

1. BACKGROUND AND BASIS OF PRESENTATION

Triumph Group, Inc. ("Triumph" or the "Company") is a Delaware corporation which, through its operating subsidiaries, designs, engineers, manufactures and sells products for the global aerospace OEMs of aircraft and aircraft components and repairs and overhauls aircraft components and accessories for commercial airline, air cargo carrier and military customers on a worldwide basis. Triumph and its subsidiaries (collectively, the "Company") are organized based on the products and services that they provide. The Company has two reportable segments: Systems & Support and Interiors (formerly Aerospace Structures).

Systems & Support consists of the Company’s operations that provide integrated solutions, including design; development; and support of proprietary components, subsystems and systems, as well as production of complex assemblies using external designs. 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 heat exchange technology; fuel pumps, fuel metering units, and Full Authority Digital Electronic Control fuel systems; and hydromechanical and electromechanical primary and secondary flight controls. Systems & Support also provides full life cycle solutions for commercial, regional, and military aircraft. The Company’s 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 post-production supply chain activities, Systems & Support is positioned to provide integrated planeside repair solutions globally. Capabilities include repair services for metallic and composite aircraft structures; nacelles; thrust reversers; interiors; auxiliary power units; and a wide variety of pneumatic, hydraulic, fuel, and mechanical accessories. Repair services generally involve the replacement and/or remanufacturing of parts, which is similar to the original manufacture of the part. The processes that the Company performs related to repair and overhaul services are essentially the repair of wear parts or replacement of parts that are beyond economic repair. The repair service generally involves remanufacturing a complete part or a component of a part.

Interiors (formerly Aerospace Structures) consists of the Company’s operations that have historically supplied commercial, business, and regional manufacturers with large metallic structures and continues to supply aircraft interior systems, including air ducting and thermal acoustic insulations systems. Subsequent to the divestitures disclosed in Note 3, the remaining operations of Interiors (formerly Aerospace Structures) are those that supply commercial and regional manufacturers with aircraft interior systems.

The accompanying consolidated financial statements include the accounts of Triumph and its wholly-owned subsidiaries. Intercompany accounts and transactions have been eliminated from the consolidated financial statements.

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates.

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Cash and Cash Equivalents

Cash equivalents consist of highly liquid investments with a maturity of three months or less at the time of purchase. Fair value of cash equivalents approximates carrying value.

Trade and Other Receivables, net

Trade and other receivables are recorded net of an allowance for expected credit losses. Trade and other receivables include amounts billed and currently due from customers and amounts retained by the customer pending contract completion. The Company performs ongoing credit evaluations of its customers and generally does not require collateral. The Company pools receivables that share underlying risk characteristics and records the allowance for expected credit losses based on a combination of prior experience, current economic conditions and management’s expectations of future economic conditions, and specific collectibility matters when they arise. The Company writes off balances against the allowance for expected credit losses when collectibility is deemed remote. The Company's trade and other receivables are exposed to credit risk; however, the risk is limited due to the diversity of the customer base. For the years ended March 31, 2023 and 2022, credit loss expense and write-offs were immaterial.

Trade and other receivables, net composed of the following:

	March 31,
	2023			2022
Total trade receivables	$	163,104		$	169,978
Other receivables		42,053			16,625

Less: Allowance for credit losses		(8,382	)		(7,940	)
Total trade and other receivables, net	$	196,775		$	178,663

Goodwill and Intangible Assets

The Company accounts for goodwill and intangible assets in accordance with ASC 350, Intangibles—Goodwill and Other. Under ASC 350, goodwill and intangible assets with indefinite lives are not amortized; rather, they are tested for impairment on at least an annual basis. Intangible assets with finite lives are amortized over their useful lives.

The Company assesses whether goodwill impairment exists using both the qualitative and quantitative assessments. The qualitative assessment involves determining whether events or circumstances exist that indicate it is more likely than not that the fair value of a reporting unit is less than its carrying amount, including goodwill. If based on this qualitative assessment the Company determines it is more likely than not that the fair value of a reporting unit is less than its carrying amount or if the Company elects not to perform a qualitative assessment, a quantitative assessment is performed as required by ASC 350 to determine whether a goodwill impairment exists at the reporting unit.

The quantitative test is used to compare the carrying amount of the reporting unit's assets to the fair value of the reporting unit. If the fair value exceeds the carrying value, no further evaluation is required, and no impairment loss is recognized. If the carrying amount exceeds the fair value, then an impairment loss occurs. The impairment is measured by using the amount by which the carrying value exceeds the fair value not to exceed the amount of recorded goodwill. The determination of the fair value of its reporting units is based, among other things, on estimates of future operating performance of the reporting unit being valued. The Company is required to complete an impairment test for goodwill and record any resulting impairment losses at least annually. Changes in market conditions, among other factors, may have an impact on these estimates and require interim impairment assessments.

When performing the quantitative impairment test, the Company's methodology includes the use of an income approach which discounts future net cash flows to their present value at a rate that reflects the Company's cost of capital, otherwise known as the discounted cash flow method ("DCF"). These estimated fair values are based on estimates of future cash flows of the businesses. Factors affecting these future cash flows include the continued market acceptance of the products and services offered by the businesses, the development of new products and services by the businesses and the underlying cost of development, the future cost structure of the businesses and future technological changes. The Company also incorporates market multiples for comparable companies in determining the fair value of its reporting units. Any such impairment would be recognized in full in the reporting period in which it has been identified. The fair value estimates resulting from the application of these methodologies are based on inputs classified within Level 3 of the fair value hierarchy, as described below.

During the fourth quarter of the fiscal years ended March 31, 2023 and 2022, the Company performed its annual goodwill impairment assessment for each of its reporting units with no impairment identified.

Finite-lived intangible assets are amortized over their useful lives ranging from 10 to 30 years. The Company continually evaluates whether events or circumstances have occurred that would indicate that the remaining estimated useful lives of long-lived assets, including intangible assets, may warrant revision or that the remaining balance may not be recoverable. Long-lived assets are evaluated for indicators of impairment. When factors indicate that long-lived assets, including intangible assets, should be evaluated for possible impairment, an estimate of the related undiscounted cash flows over the remaining life of the long-lived assets, including intangible assets, is used to measure recoverability based on the primary asset of the asset group. Some of the more important factors management considers include the Company's financial performance relative to expected and historical performance, significant changes in the way the Company manages its operations, negative events that have occurred, and negative industry and economic trends. If the estimated undiscounted cash flows are less than the carrying amount, measurement of the impairment will be based on the difference between the carrying value and fair value of the asset group, generally determined based on the present value of expected future cash flows associated with the use of the asset.

In fiscal 2021, the Company's Board of Directors committed to a plan (i) to sell its composites manufacturing operations located in Milledgeville, Georgia, and Rayong, Thailand, and (ii) to transfer the assets and certain liabilities associated with its Gulfstream G650 wing supply chain activities (as disclosed in Note 3, this transaction closed in August 2020). These planned divestitures

represented the divestiture of certain assets and liabilities of an operating business within the Interiors (formerly Aerospace Structures) segment that the Company had identified as an asset group pursuant to the provisions of ASC 360, Property, Plant, and Equipment. As a result, as of May 31, 2020, the Company concluded that the planned divestitures represented a significant change in the manner in which the related asset group was expected to be used, and that the asset group therefore needed to be tested for recoverability. The asset group primarily consisted of working capital, fixed assets and definite-lived intangible assets. The Company first determined that the relevant long-lived asset group was not recoverable by comparing the undiscounted cash flows expected to be generated by the long-lived asset group to the carrying value of the asset group. As a result, the Company estimated the fair value of the long-lived asset group and concluded that the asset group was impaired. The Company used a multi-period excess earnings approach to estimate the fair value of the long-lived asset group for purposes of testing the asset group for impairment. This method estimates fair value based on the expected future excess earnings stream attributable to the asset group. This method requires the use of several key assumptions, including revenue projections that consider historical and estimated future results, general economic and market conditions, as well as the impact of planned business and operational strategies. A discount rate of 15.0% was applied to the estimated future excess earnings and cash flows in order to estimate the fair value of the asset group as of the measurement date. The Company has determined that the lowest level of the inputs that are significant to the fair value measurement are unobservable inputs that fall within Level 3 of the fair value hierarchy.

In accordance with ASC 360, the Company allocated the resulting impairment to the specific long-lived assets within the asset group on a pro rata basis, except that the loss allocated to an individual long-lived asset of the group did not reduce the carrying amount of that asset below its estimated fair value. As a result, the Company recognized a total noncash impairment charge of $252,382 in the first quarter, primarily allocated to definite-lived intangible assets, which is presented as “Impairment of long-lived assets” on the accompanying consolidated statements of operations. In January 2021, the Company’s Board of Directors committed to a plan to sell its manufacturing operations located in Red Oak, Texas. As a result of this decision and the resulting classification of this disposal group as held for sale, the Company fully impaired the remaining customer relationship intangible asset within the Interiors (formerly Aerospace Structures) segment and recognized a noncash impairment charge of $6,696, which has been included in the impairment on the assets held for sale as disclosed in Note 3 and is presented within “(Gain) loss on sale of assets and businesses” on the accompanying consolidated statement of operations.

See below for the Company's accounting policy regarding fair value measurements and the definition of fair value levels.

Revenue Recognition and Contract Balances

The Company's revenue is principally from contracts with customers to provide design, development, manufacturing, and support services associated with specific customer programs. The Company regularly enters into long-term master supply agreements that establish general terms and conditions and may define specific program requirements. Many agreements include clauses that provide sole supplier status to the Company for the duration of the program’s life. Purchase orders (or authorizations to proceed) are issued pursuant to the master supply agreements. Additionally, a majority of the Company’s agreements with customers include options for future purchases. Such options primarily reduce the administrative effort of issuing subsequent purchase orders and do not represent material rights granted to customers. The Company generally enters into agreements directly with its customers and is the principal in all current contracts.

The identification of a contract with a customer for purposes of accounting and financial reporting requires an evaluation of the terms and conditions of agreements to determine whether presently enforceable rights and obligations exist. Management considers a number of factors when making this evaluation that include, but are not limited to, the nature and substance of the business exchange, the specific contractual terms and conditions, the promised products and services, the termination provisions in the contract, as well as the nature and execution of the customer’s ordering process and how the Company is authorized to perform work. Generally, presently enforceable rights and obligations are not created until a purchase order is issued by a customer for a specified number of units of product or services. Therefore, the issuance of a purchase order is generally the point at which a contract is identified for accounting and financial reporting purposes.

Management identifies the promises to the customer. Promises are generally explicitly stated in each contract, but management also evaluates whether any promises are implied based on the terms of the agreement, past business practice, or other facts and circumstances. Each promise is evaluated to determine if it is a performance obligation. A performance obligation is a promise in a contract to transfer a distinct good or service. The Company considers a number of factors when determining whether a promise is a distinct performance obligation, including whether the customer can benefit from the good or service on its own or together with other resources that are readily available to the customer, whether the Company provides a significant service of integrating goods or services to deliver a combined output to the customer, or whether the goods or services are highly interdependent. The Company’s performance obligations consist of a wide range of engineering design services and manufactured components, as well as spare parts and repairs for OEMs.

The transaction price for a contract reflects the consideration the Company expects to receive for fully satisfying the performance obligations in the contract. Typically, the transaction price consists solely of fixed consideration but may include variable consideration for contractual provisions such as unpriced contract modifications, cost-sharing provisions, and other receipts or payments to customers. The Company identifies and estimates variable consideration, typically at the most likely amount the Company expects to receive from its customers. Variable consideration is only included in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized for the contract will not occur, or when the uncertainty associated with the variable consideration is resolved. Consideration paid or payable to a customer is reflected as a reduction in net revenues when the amounts paid are not related to a distinct good or service at the later of when the related revenue is recognized or when the Company pays or promises to pay the consideration to the customer. The Company's contracts with customers generally require payment under normal commercial terms after delivery with payment typically required within 30 to 120 days of delivery.

The Company generally is not subject to collecting sales tax and has made an accounting policy election to exclude from the transaction price any sales and other similar taxes collected from customers. As a result, any such collections are accounted for on a net basis.

The total transaction price is allocated to each of the identified performance obligations using the relative stand-alone selling price. The objective of the allocation is to reflect the consideration that the Company expects to receive in exchange for the products or services associated with each performance obligation. Stand-alone selling price is the price at which the Company would sell a promised good or service separately to a customer. Stand-alone selling prices are established at contract inception, and subsequent changes in transaction price are allocated on the same basis as at contract inception. When stand-alone selling prices for the Company’s products and services are not observable, the Company uses either the “Expected Cost Plus a Margin” or "Adjusted Market Assessment" approaches to estimate stand-alone selling price. Expected costs are typically derived from the available periodic forecast information.

Revenue is recognized when or as control of promised products or services transfers to a customer and is recognized at the amount allocated to each performance obligation associated with the transferred products or services. Service sales, principally representing repair, maintenance, and engineering activities are recognized over the contractual period or as services are rendered. Sales under long-term contracts with performance obligations satisfied over time are recognized using either an input or output method. The Company recognizes revenue over time as it performs on these contracts because of the continuous transfer of control to the customer as represented by contractual terms that entitle the Company to the reimbursement of costs plus a reasonable profit for work performed to manufacture products for which the Company has no alternate use or for work performed on a customer-owned asset.

With control transferring over time, revenue is recognized based on the extent of progress toward completion of the performance obligation. The Company generally uses the cost-to-cost input method of progress for its contracts because it best depicts the transfer of control to the customer that occurs as work progresses. Under the cost-to-cost method, the extent of progress toward completion is measured based on the proportion of costs incurred to date to the total estimated costs at completion of the performance obligation. The Company reviews its cost estimates on contracts on a periodic basis, or when circumstances change and warrant a modification to a previous estimate. Cost estimates are largely based on negotiated or estimated purchase contract terms, historical performance trends and other economic projections. Significant factors that influence these estimates include inflationary trends, technical and schedule risk, internal and subcontractor performance trends, business volume assumptions, asset utilization, and anticipated labor agreements.

Revenue and cost estimates are regularly monitored and revised based on changes in circumstances. Impacts from changes in estimates of net sales and cost of sales are recognized on a cumulative catch-up basis, which recognizes in the current period the cumulative effect of the changes on current and prior periods based on a performance obligation’s percentage of completion. Forward loss reserves for anticipated losses on long-term contracts are recorded in full when such losses become evident, to the extent required and are included in contract liabilities on the accompanying consolidated balance sheets. The Company believes

that the accounting estimates and assumptions made by management are appropriate, however actual results could differ materially from those estimates.

For the fiscal year ended March 31, 2023, cumulative catch-up adjustments resulting from changes in contract values and estimated costs that arose during the fiscal year increased revenue, operating income, net income, and diluted earnings per share by approximately $21,208, $27,963, $27,963, and $0.39, respectively. The cumulative catch-up adjustments to operating income for the fiscal year ended March 31, 2023, included gross favorable adjustments of approximately $32,699 and gross unfavorable adjustments of approximately $4,736.

For the fiscal year ended March 31, 2022, cumulative catch-up adjustments resulting from changes in estimates increased revenue and decreased operating loss, net loss, and diluted loss per share by approximately $6,884, $16,042, $16,042, and $0.25, respectively. The cumulative catch-up adjustments to operating income for the fiscal year ended March 31, 2022, included gross favorable adjustments of approximately $30,560 and gross unfavorable adjustments of approximately $14,518.

For the fiscal year ended March 31, 2021, cumulative catch-up adjustments resulting from changes in estimates increased revenue and decreased operating loss, net loss, and diluted loss per share by approximately $4,796, $12,332, $12,332, and $0.23, respectively. The cumulative catch-up adjustments to operating income for the fiscal year ended March 31, 2021, included gross favorable adjustments of approximately $55,180 and gross unfavorable adjustments of approximately $42,848.

Revenues for performance obligations that are not recognized over time are recognized at the point in time when control transfers to the customer. For performance obligations that are satisfied at a point in time, the Company evaluates the point in time when the customer can direct the use of and obtain the benefits from the products and services. Generally, the shipping terms determine the point in time when control transfers to customers. Shipping and handling activities are not considered performance obligations and related costs are included in cost of sales as incurred.

Differences in the timing of revenue recognition and contractual billing and payment terms result in the recognition contract assets and liabilities. Refer to Note 4 for further discussion.

Warrants

On December 1, 2022, the Company’s board of directors declared a distribution to holders of the Company’s shares of common stock in the form of warrants to purchase shares of common stock (the “Warrants”). Holders of common stock received three Warrants for every ten shares of common stock held as of December 12, 2022 (the "Record Date") (rounded down for any fractional warrant). The Company issued approximately 19.5 million Warrants on December 19, 2022, to holders of record of common stock as of the close of business on the Record Date. The Warrants trade on the over-the-counter market.

Each Warrant represents the right to purchase initially one share of common stock, subject to certain anti-dilution adjustments (“Warrant Shares Per Warrant”), at an exercise price of $12.35 per Warrant (the “Exercise Price”), subject to certain anti-dilution adjustments (the “Implied Per Share Exercise Price”). Payment for shares of common stock on exercise of Warrants may be in (i) cash or (ii) under certain circumstances, Designated Notes (as defined below). In the event Designated Notes are used to pay for the exercise of the Warrants, accrued interest (in addition to the stated aggregate principal amount) will be forfeited upon exercise, unless exercise occurs after a record date for the payment of interest and before the resulting scheduled payment date (in which case note holders will receive the scheduled interest payment). If all Warrants were exercised and settled as of March 31, 2023, the Company would be required to issue approximately 19.1 million shares (assuming no over-exercise options, as described below, were exercised). The closing price of the Company’s shares of common stock was $11.59 as of March 31, 2023.

“Designated Notes” means, collectively, any of the issued and outstanding notes of the Company as designated or undesignated by the Company from time to time; provided that any designation by the Company of a particular series of notes as “Designated Notes” shall retain such designation for a minimum of 20 consecutive business days from (and including) the date of publication of notice of the same by press release. The Company also has the right, but not obligation, to remove one or more series of its notes from being “Designated Notes,” but such redesignation shall only be effective 20 consecutive business days from (and including) the date of publication of notice of the same by press release. The Company initially designated the following notes as “Designated Notes,” each as defined in above: the 2024 First Lien Notes, the 2024 Second Lien Notes, and the 2025 Notes. On February 3, 2023, the Company published a press release announcing the de-designation of the 2024 First Lien Notes and the 2024 Second Lien Notes.

Pursuant to the terms of the Warrant Agreement, a holder may elect to pay an additional amount equal to $1.8525 (being 0.15 multiplied by the Exercise Price) in exchange for an additional number of shares of common stock equal to the product of 0.15 and the Warrant Shares Per Warrant applicable to the relevant exercise on the terms specified in the Warrant Agreement. If all Warrants were exercised as of March 31, 2023 and each holder were to elect to pay the additional $1.8525 to receive additional

shares, the Company would be required to issue an additional approximately 2.9 million shares in settlement of the incremental exercise price received.

The Warrants expire on December 19, 2023, subject to (i) the right of the Company to redeem the Warrants on not less than 20 calendar days’ notice (any such date of redemption, the “Redemption Date” and any such date of notice a “Redemption Notice”) at a price of 1/10 of $0.01 per Warrant and (ii) the automatic acceleration of the Expiration Date following the Price Condition Date, as defined and described below.

Unless the Company has previously issued a Redemption Notice with respect to the Warrants, then following the last day of the first 30 consecutive trading day period to occur in which daily volume weighted average prices of the shares of Common Stock has been at least equal to the then applicable Implied Per Share Exercise Price on each of 20 trading days (whether or not consecutive) (the “Price Condition”), the Expiration Date will automatically accelerate to the date that is the 5th business day following the Price Condition Date; provided that the Company may, at its sole option, elect a later Expiration Date by providing public notice no later than the Price Condition Date. The “Price Condition Date” is the first business day following the last Trading Day of the period in which the Price Condition is met.

Any holder that exercises any Warrants from and after (a) 5:00 p.m. New York city time on the earlier of (x) a Price Condition Date and (y) the date that the Company issues a Redemption Notice until (b) 5:00 p.m. New York City time on, as applicable, (x) the Expiration Date and (y) the business day immediately preceding the Redemption Date (the last day of such period, the “Over-Subscription Deadline”), may, subject to the terms of the Warrant Agreement, elect to subscribe for any or all of the shares of Common Stock issuable pursuant to any outstanding but unexercised Warrants as of the Over-Subscription Deadline (the “Over-Subscription Privilege”). To exercise the Over-Subscription Privilege, a holder must deliver an amount in cash equal to the elected over-subscription shares multiplied by the then applicable Implied Per Share Exercise Price (such amount, the “Elected Over-Subscription Shares Amount”) at the same time as the basic warrant exercise right is exercised. Any excess payments received will be returned, without interest, promptly following the settlement date.

An ownership limitation is in place such that a holder of Warrants is not permitted to exercise Warrants for any shares of common stock if following such exercise the holder will have beneficial ownership of common stock in excess of 4.9% of the then issued and outstanding common stock (excluding shares held by subsidiaries); provided, that a holder of Common Stock in excess of 4.9% of the issued and outstanding common stock as of 5:00 p.m. New York City time on December 1, 2022 will be entitled to exercise Warrants received in the Warrant Distribution, but only to the extent such holder’s receipt of such common stock is permitted by a waiver in effect at such time that constitutes “Prior Approval of the Company” under the Tax Benefit Preservation Plan, dated March 11, 2022, between the Company and Computershare Trust Company, N.A., as rights agent.

The Exercise Price and the number of shares of common stock issuable upon exercise are subject to certain anti-dilution adjustments, including for share dividends, splits, subdivisions, spin-offs, consolidations, reclassifications, combinations, noncash distributions, and cash dividends.

The common stock warrants are accounted for as derivative liabilities in accordance with ASC 815-40 and included within accrued liabilities on the accompanying condensed consolidated balance sheets. The Company measured the Warrants at fair value as of the issuance date using a Monte Carlo pricing model, a Level 3 fair value measurement (as described below), due to the level of market activity. Inherent in the option pricing simulation are assumptions related to expected stock-price volatility, expected life and risk-free interest rate. The Company estimates the volatility of the Warrants based on implied and historical volatility of the Company’s common stock. The risk-free interest rate is based on the U.S. Treasury zero-coupon yield curve on the grant date for a maturity similar to the expected remaining life of the Warrants. The expected life of the Warrants is based on the Company’s ability to redeem the Warrants, subject to a 20 calendar-day notice period, as well as the automatic acceleration of the Expiration Date following the Price Condition Date. During the three months ended December 31, 2022, due to increased trading volume, the Company began remeasuring outstanding Warrants using the Warrants trading price, a Level 1 fair value measurement (as described below). The Warrants are remeasured at each balance sheet date. Warrants remeasurement adjustments are recognized in warrants remeasurement gain, net on the accompanying condensed consolidated statements of operations.

At distribution, the fair value of the Warrants was $19,500. At March 31, 2023, the fair value of the Warrants was approximately $9,563 and $9,796 of warrants remeasurement gain has been recognized in the year ended March 31, 2023. Following the issuance on December 19, 2022 through March 31, 2023, approximately 0.4 million Warrants have been exercised

Leases

The Company leases office space, manufacturing facilities, land, vehicles, and equipment. The Company determines if an agreement is or contains a lease at the lease inception date and recognizes right-of-use assets (“ROU”) and lease liabilities at the

lease commencement date. A ROU asset and corresponding lease liability are not recorded for leases with an initial term of 12 months or less (“short-term leases”).

ROU assets represent the Company's right to use an underlying asset during the lease term, and lease liabilities represent the Company's obligation to make lease payments arising from the lease. The determination of the length of lease terms is affected by options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. The existence of significant economic incentive is the primary consideration when assessing whether the Company is reasonably certain of exercising an option in a lease. Both finance and operating lease ROU assets and liabilities are recognized at commencement date and measured as the present value of lease payments to be made over the lease term. As the interest rate implicit in the lease is not readily available for most of the Company's leases, the Company uses its estimated incremental borrowing rate in determining the present value of lease payments. The estimated incremental borrowing rate is derived from information available at the lease commencement date. The lease ROU asset recognized at commencement is adjusted for any lease payments related to initial direct costs, prepayments, and lease incentives.

For operating leases, lease expense is recognized on a straight-line basis over the lease term. For finance leases, lease expense comprises the amortization of the ROU assets recognized on a straight-line basis generally over the shorter of the lease term or the estimated useful life of the underlying asset and interest on the lease liability. Variable lease payments not dependent on a rate or index are recognized when the event, activity, or circumstance in the lease agreement upon which those payments are contingent is probable of occurring and are presented in the same line of the consolidated balance sheet as the rent expense arising from fixed payments. The Company has lease agreements with lease and non-lease components. Non-lease components are combined with the related lease components and accounted for as lease components for all classes of underlying assets.

Retirement Benefits

Defined benefit pension plans are recognized in the consolidated financial statements on an actuarial basis. A significant element in determining the Company's pension (income) expense is the expected long-term rate of return on plan assets. This expected return is an assumption as to the average rate of earnings expected on the funds invested or to be invested to provide for the benefits included in the projected pension benefit obligation. The Company applies this assumed long-term rate of return to a calculated value of plan assets, which recognizes changes in the fair value of plan assets in a systematic manner over five years. This produces the expected return on plan assets that is included in pension (income) expense. The difference between this expected return and the actual return on plan assets is deferred. The net deferral of past asset (losses) gains affects the calculated value of plan assets and, ultimately, future pension (income) expense.

The Company periodically experiences events or makes changes to its benefit plans that result in curtailment or special charges. Curtailments are recognized when events occur that significantly reduce the expected years of future service of present employees or eliminates the benefits for a significant number of employees for some or all of their future service.

Curtailment losses are recognized when it is probable the curtailment will occur and the effects are reasonably estimable. Curtailment gains are recognized when the related employees are terminated or a plan amendment is adopted, whichever is applicable.

From time to time, the Company may enter into transactions that relieve it of primary responsibility for all or more than a minor portion of certain of its pension benefit obligations. When these transactions are effected through an irrevocable action that relieves the Company of primary responsibility for its pension or other postretirement benefit obligations and eliminates significant risks related to the obligation and the related assets used to effect the transaction, they are considered settlements, as defined by ASC 715, Compensation – Retirement Benefits. When a transaction meets the definition of a settlement, at the time of settlement the Company recognizes as a gain or loss the pro rata amount of the net gain or loss in accumulated other comprehensive loss based on the proportion of the projected benefit obligation settled to the total projected benefit obligation.

As required under ASC 715, the Company remeasures plan assets and obligations during an interim period whenever a significant event occurs that results in a material change in the net periodic pension cost. The determination of significance is based on judgment and consideration of events and circumstances impacting the pension costs.

At March 31 of each year, the Company determines the fair value of its pension plan assets as well as the discount rate to be used to calculate the present value of plan liabilities. The discount rate is an estimate of the interest rate at which the pension benefits could be effectively settled. In estimating the discount rate, the Company looks to rates of return on high-quality, fixed-income investments currently available and expected to be available during the period to maturity of the pension benefits. The Company uses a portfolio of fixed-income securities, which receive at least the second-highest rating given by a recognized ratings agency.

Contingencies

Contingences are existing conditions, situations or circumstances involving uncertainty as to possible gain or loss that will ultimately be resolved when future events occur or fail to occur. Such contingencies include, but are not limited to environmental obligations, litigation, regulatory investigations and proceedings, product quality, and gains or losses resulting from other events and developments. Liabilities for loss contingencies are accrued in the amount of its best estimate for the ultimate loss when a loss is considered probable of having been incurred and is reasonably estimable. When there appears to be a range of possible costs with equal likelihood, liabilities are based on the low-end of such range. Disclosure is provided for material loss contingencies when a loss is probable but a reasonable estimate cannot be made, and when it is reasonably possible that a loss will be incurred or the amount of a loss will exceed the recorded provision. The Company regularly reviews contingencies to determine whether the likelihood of loss has changed and to assess whether a reasonable estimate of the loss or range of loss can be made. Contingencies that might result in gains are generally not accrued until the contingencies are resolved and the gain is realized or realizable. Refer to Note 17 for further disclosure.

Fair Value Measurements

Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. When determining fair value measurements for assets and liabilities required to be recorded at fair value, the Company considers the principal or most advantageous market in which it would transact and also considers assumptions that market participants would use when pricing an asset or liability. The fair value hierarchy has three levels of inputs that may be used to measure fair value: Level 1—Unadjusted quoted prices in active markets for identical assets or liabilities; Level 2—Unadjusted quoted prices in active markets for similar assets or liabilities, or unadjusted quoted prices for identical or similar assets or liabilities in markets that are not active, or inputs other than quoted prices that are observable for the asset or liability; and Level 3—Unobservable inputs for the asset or liability. The Company has applied fair value measurements when measuring the warrants (refer to the above disclosure), when comparing the carrying value of assets held for sale with the related fair value less cost to sell (see Note 3), when measuring long-lived asset impairment in fiscal 2021 (see above within the disclosure of the Company’s goodwill and intangible asset accounting policies), when disclosing the fair value of its long-term debt not recorded at fair value (see Note 10) and when measuring its pension and postretirement plan assets (see Note 15).

Income Taxes

The Company accounts for income taxes using the asset and liability method. The asset and liability method requires recognition of deferred tax assets and liabilities for expected future tax consequences of temporary differences that currently exist between tax bases and financial reporting bases of the Company's assets and liabilities. A valuation allowance is provided on deferred taxes if it is determined that it is more likely than not that the asset will not be realized.

Management judgment is required to determine the amount of benefit to be recognized in relation to an uncertain tax position. The Company uses a two-step process to evaluate tax positions. The first step requires an entity to determine whether it is more likely than not (greater than 50% chance) that the tax position will be sustained. The second step requires an entity to recognize in the financial statements the benefit of a tax position that meets the more-likely-than-not recognition criterion. The amounts ultimately paid upon resolution of issues raised by taxing authorities may differ materially from the amounts accrued and may materially impact the financial statements of the Company in future periods. The Company recognizes penalties and interest accrued related to income tax liabilities in the provision for income taxes on its consolidated statements of operations.

Supplemental Cash Flow Information

In November 2021, the Company entered into an agreement with the DOT under the AMJP for a grant of up to $21,259. The receipt of the full award was primarily conditioned upon the Company committing to not furlough or lay off a defined group of employees during the six-month period of performance between November 2021 and May 2022. The Company received approximately $19,400 under the agreement, of which approximately $10,630 was received in the year ended March 31, 2022, and the remainder of which was received in the year ended March 31, 2023. In July 2022, the Company received a letter from the DOT confirming that the Company had satisfied the reporting requirements under the AMJP. In the twelve months ended March 31, 2023 and 2022, the Company recognized as a reduction in cost of sales approximately $5,300 and $14,064, respectively, the former representing the final balance of the earned grant benefit.

For the fiscal years ended March 31, 2023, 2022, and 2021, the Company paid $4,565, $5,382, and $2,297, respectively, for income taxes, net of income tax refunds received.

Fiscal 2023 Divestitures

In January 2022, the Company’s Board of Directors committed to a plan to sell its manufacturing operations located in Stuart, Florida. In February 2022, the Company entered into a definitive agreement with the buyer of these manufacturing operations. This transaction closed in July 2022. The Company recognized a gain of approximately $96,800, net of transaction costs, in the year ended March 31, 2023. The purchase price included the assumption of certain liabilities of the Company; no cash proceeds were received in the transaction. The operating results of the Stuart, Florida, manufacturing operations are included within the Interiors (formerly Aerospace Structures) reportable segment through the date of divestiture.

In the year ended March 31, 2023, the Company recognized a gain of approximately $4,500 from working capital settlements related to the fiscal 2022 divestitures described below.

Fiscal 2022 Divestitures

In May 2020, the Company’s Board of Directors committed to a plan to sell its composites manufacturing operations located in Milledgeville, Georgia and Rayong, Thailand. In August 2020, the Company entered into a definitive agreement with the buyer of the composites manufacturing operations in Georgia and Thailand. In February 2021, the Company entered into a definitive agreement to sell its large structure manufacturing operations in Red Oak, Texas, to the same buyer of the Milledgeville and Rayong composites manufacturing operations. In the year ended March 31, 2021, the Company adjusted the carrying amount of these assets held for sale to its estimated fair value less cost to sell and recognized a loss in that period of approximately $102,500, which is included in (gain) loss on sale of assets and businesses. The estimate of fair value is categorized as Level 2 within the fair value hierarchy. The key assumptions used in the estimate of fair value were the negotiated sales price of the assets and the assumption of the disposal group’s liabilities. These transactions closed in May 2021. Upon the completion of the sale of the composites and large structure manufacturing operations, the Company received proceeds of approximately $155,000 net of the purchase of a facility related to the divestiture and other transaction costs and recognized an additional loss of approximately $6,000, which is presented on the accompanying condensed consolidated statements of operations within (gain) loss on sale of assets and businesses for the year ended March 31, 2022. The loss was primarily the result of changes in the working capital balances of the disposal group from March 31, 2021, to the date of divestiture. The operating results of these related operations are included within the Interiors (formerly Aerospace Structures) reportable segment through the date of divestiture. As disclosed in Note 15, as a result of the completed sale of these manufacturing operations, the Company recognized a curtailment loss of approximately $16,000 during the three months ended June 30, 2021.

In August 2021, the Company’s Board of Directors committed to a plan to sell and license certain legacy product lines of the Company’s Staverton, United Kingdom operations. The transaction includes the existing facility and select product lines associated with the site. The transaction closed in October 2021 for net proceeds of approximately $34,000, and the effect on earnings was insignificant. The operating results of the Staverton, United Kingdom, manufacturing operations were included within the Systems & Support reportable segment through the date of divestiture.

As a result of the fiscal 2022 divestitures described above, including routine closing working capital adjustments, the Company recognized losses of approximately $8,000 in the three months ended September 30, 2021.

Fiscal 2021 Divestitures

In August 2020, the Company completed the transfer of the assets and certain liabilities associated with its Gulfstream G650 wing supply chain activities for cash proceeds net of transaction costs of approximately $51,000. This transaction also resulted in the derecognition of approximately $18,157 in accrued warranties related to these activities. The Company recognized a loss of approximately $819, which is presented on the accompanying consolidated statements of operations within (gain) loss on sale of assets and businesses. The operating results associated with the G650 wing supply chain activities were included within Interiors (formerly Aerospace Structures) through the date of transfer.

Contract Assets and Liabilities

Contract assets primarily represent revenues recognized for performance obligations that have been satisfied or partially satisfied but for which amounts have not been billed. This typically occurs when revenue is recognized over time but the Company's contractual right to bill the customer and receive payment is conditional upon the satisfaction of additional performance obligations in the contract, such as final delivery of the product. Contract assets are typically derecognized when billed in accordance with the terms of the contract. The Company pools contract assets that share underlying risk characteristics and records an allowance for expected credit losses based on a combination of prior experience, current economic conditions and management’s expectations of future economic conditions, and specific matters when they arise. Contract assets are presented net of this reserve on the accompanying consolidated balance sheets. For the years ended March 31, 2023 and 2022, credit loss expense and write-offs related to contract assets were immaterial.

Contract liabilities are recorded when customers remit contractual cash payments in advance of the Company satisfying performance obligations under contractual arrangements, including those with performance obligations to be satisfied over a period of time. Contract liabilities other than those pertaining to forward loss reserves are derecognized when or as revenue is recognized.

Contract modifications can also impact contract asset and liability balances. When contracts are modified to account for changes in contract specifications and requirements, the Company considers whether the modification either creates new or changes the existing enforceable rights and obligations. Contract modifications that are for goods or services that are not distinct from the existing contract, due to the significant integration with the original good or service provided, are accounted for as if they were part of that existing contract. The effect of a contract modification to an existing contract on the transaction price and the Company’s measure of progress for the performance obligation to which it relates, is recognized as an adjustment to revenue (either as an increase in or a reduction of revenue) on a cumulative catch-up basis. When the modifications include additional performance obligations that are distinct and at relative stand-alone selling price, they are accounted for as a new contract and performance obligation, which are recognized prospectively.

Contract balances are classified as assets or liabilities on a contract-by-contract basis at the end of each reporting period. The following table summarizes the Company’s contract assets and liabilities balances:

	March 31, 2023			March 31, 2022			Change
Contract assets	$	103,027		$	101,893		$	1,134
Contract liabilities		(44,945	)		(172,862	)		127,917
Net contract asset (liability)	$	58,082		$	(70,969	)	$	129,051

The Company recognized revenue due to changes in estimates associated with performance obligations satisfied or partially satisfied in previous periods of $21,208. The change in contract assets was not significant in the year ended March 31, 2023. The change in contract liabilities is the result of revenue recognized in excess of the receipt of additional customer advances as well as the extinguishment of approximately $103,803 of customer advance repayment obligations that were assumed by the buyer of the Stuart, Florida, manufacturing operations. For the period ended March 31, 2023, the Company recognized $46,779 of revenue that was included in the contract liability balance at the beginning of the period.

Performance Obligations

Customers generally contract with the Company for requirements in a segment relating to a specific program, and the Company’s performance obligations consist of a wide range of engineering design services and manufactured components, as well as spare parts and repairs. A single contract may contain multiple performance obligations consisting of both recurring and nonrecurring elements.

As of March 31, 2023, the Company has the following unsatisfied, or partially unsatisfied, performance obligations that are expected to be recognized in the future as noted in the table below. The Company expects options to be exercised in addition to the amounts presented below.

	Total		Less than 1 year		1-3 years		4-5 years		More than 5 years

Receivables Securitization Program

In connection with the Securitization Facility, the Company sells on a revolving basis certain eligible accounts receivable to Triumph Receivables, LLC, a wholly-owned special-purpose entity, which in turn sells a percentage ownership interest in the receivables to commercial paper conduits sponsored by financial institutions. The Company is the servicer of the trade accounts receivable under the Securitization Facility. Interest rates are based on the Bloomberg Short Term Bank Yield Index (“BSBY”), plus a 2.25% fee on the drawn portion and a fee ranging from 0.45% to 0.50% on the undrawn portion of the Securitization Facility. The drawn fee may be reduced to 2.00% depending on the credit rating of the Company. Collateralized letters of credit incur fees at a rate of 0.125%. The Company secures its trade accounts receivable, which are generally non-interest-bearing, in transactions that are accounted for as borrowings pursuant to ASC 860, Transfers and Servicing. The Company has established a letter of credit facility under the Securitization Facility. Under the provisions of the letter of credit facility, the Company may request the Securitization Facility’s administrator to issue one or more letters of credit that will expire no later than 12 months after the date of issuance, extension or renewal, as applicable.

As of March 31, 2023, the maximum amount available under the Securitization Facility was $100,000. The actual amount available under the Securitization Facility at any point in time is dependent upon the balance of eligible accounts receivable as well as the amount of letters of credit outstanding.

At March 31, 2023 and 2022, there were $0 in borrowings and $19,753 and $23,339, respectively, in letters of credit outstanding under the Securitization Facility, primarily to support insurance policies. The Securitization Facility expires in November 2024.

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

Senior Secured First Lien Notes due 2028

On March 14, 2023, the Company issued $1,200,000 principal amount of 9.000% Senior Secured First Lien Notes due March 15, 2028, pursuant to an indenture among the Company, the Guarantor Subsidiaries, and U.S. Bank National Association, as trustee. The 2028 First Lien Notes were sold at 100% of the principal amount and have an effective interest yield of 9.000%. Interest is payable semi-annually in cash in arrears on March 15 and September 15 of each year, commencing on September 15, 2023. In connection with the issuance of the 2028 First Lien Notes, the Company incurred approximately $20,000 of costs, which were deferred and are being amortized over the term of the 2028 First Lien Notes.

The 2028 First Lien Notes and the guarantees are first lien secured obligations of the Company and the Guarantor Subsidiaries. The 2028 First Lien Notes:

(i)rank equally in right of payment to any existing and future senior indebtedness of the Company and Guarantor Subsidiaries, including the 2025 Notes (as defined below);

(ii)are effectively senior to all existing and future second lien obligations and all existing and future unsecured indebtedness of the Company and the Guarantor Subsidiaries, but only to the extent of the value of the Collateral (as defined below), and after giving effect to any permitted additional first lien secured obligations and other permitted liens of senior or equal priority);

(iii)are senior in right of payment to all future subordinated indebtedness of the Company and the Guarantor Subsidiaries;

(iv)are secured by the Collateral on a pari passu basis with any future permitted additional first lien secured obligations, subject to the Collateral Trust Agreement;

(v)are effectively subordinated to any existing and future obligations of the Company and the Guarantor Subsidiaries that are secured by assets that do not constitute the Collateral, in each case, to the extent of the value of the assets securing such obligations; and

(vi)are structurally subordinated to all existing and future indebtedness and other liabilities of the Company’s existing and future subsidiaries that do not guarantee the 2028 First Lien Notes, including the Securitization Facility.

The 2028 First Lien Notes are guaranteed on a full, senior, joint and several basis by each of the Company’s domestic restricted subsidiaries (the “Guarantor Subsidiaries”) that guarantees the 2025 Notes. In the future, each of the Company’s domestic restricted subsidiaries (other than any domestic restricted subsidiary that is a receivable subsidiary) that (1) is not an immaterial subsidiary, (2) becomes a borrower under any of its material debt facilities or (3) guarantees (a) any of the Company’s indebtedness or (b) any indebtedness of the Company’s domestic restricted subsidiaries, in the case of either (a) or (b), incurred under any of the Company’s material debt facilities, will guarantee the 2028 First Lien Notes. Under certain circumstances, the guarantees may be released without action by, or consent of, the holder of the 2028 First Lien Notes.

The 2028 First Lien Notes and the guarantees are secured, subject to permitted liens, by first-priority liens on substantially all of the Company’s and the Guarantor Subsidiaries’ assets (including certain of the Company’s real estate assets), whether now owned or hereafter acquired, other than certain excluded property, which liens will secure permitted additional first lien obligations on a pari passu basis, subject to the Collateral Trust Agreement (the “Collateral”). Under certain circumstances, the Collateral may be released without action by, or the consent of, the holders of the 2028 First Lien Notes. The 2028 First Lien Notes and the guarantees will not be secured by the assets of Non-Guarantor Subsidiaries (as defined below), which include the unrestricted subsidiaries to whom certain of the Company’s accounts receivables are and may in the future be sold to support borrowing under the Receivables Securitization Facility.

A collateral trust agreement (the “Collateral Trust Agreement”) among the Company, the Guarantor Subsidiaries, the Collateral Trustee and U.S. Bank National Association, in its capacity as the trustee for the 2028 First Lien Notes, will set forth therein the relative rights with respect to the Collateral as among the trustee for the 2028 First Lien Notes and certain subsequent holders of

first lien obligations and covering certain other matters relating to the administration of security interests. The Collateral Trust Agreement will generally control substantially all matters related to the Collateral, including with respect to decisions, distribution of proceeds or enforcement. Pursuant to the Collateral Trust Agreement, on the issue date of the 2028 First Lien Notes the Collateral Trustee will control certain matters related to the Collateral that the Collateral Trust Agreement specifies are in its discretion. If the Company incurs certain types of additional first lien obligations, the Controlling First Lien Holders (as defined in the Collateral Trust Agreement) will have the right to control decisions relating to the Collateral that are outside the Collateral Trustee’s discretion under the Collateral Trust Agreement and the 2028 Note holders may no longer be in control of such decisions.

The Company may redeem the 2028 First Lien Notes, in whole or in part, at any time or from time to time on or after March 15, 2025, at specified redemption prices, plus accrued and unpaid interest, if any, to the redemption date. At any time or from time to time prior to March 15, 2025, the Company may redeem the 2028 First Lien Notes, in whole or in part, at a redemption price equal to 100% of their principal amount plus a make whole premium, together with accrued and unpaid interest, if any, to the redemption date. In addition, the Company may redeem up to 40% of the aggregate principal amount of the outstanding 2028 First Lien Notes prior to March 15, 2025, with the net cash proceeds from certain equity offerings at a redemption price equal to 109.000% of their principal amount, together with accrued and unpaid interest, if any, to the redemption date. The Company may redeem, at any time from time to time before March 15, 2025, up to 10% of the aggregate principal amount of the notes per annum, at a redemption price equal to 103% of the aggregate principal amount plus accrued and unpaid interest, if any, to the redemption date.

If the Company experiences specific kinds of changes of control, the Company is required to offer to purchase all of the 2028 First Lien Notes at a purchase price of 101% of their principal amount, plus accrued and unpaid interest, if any, to the date of purchase.

The 2028 First Lien Notes Indenture contains covenants that, among other things, limit the ability of the Company and its restricted subsidiaries to: (i) incur additional indebtedness; (ii) pay dividends or make other distributions; (iii) make other restricted payments and investments; (iv) create liens; (v) incur restrictions on the ability of restricted subsidiaries to pay dividends or make certain other payments; (vi) sell assets, including capital stock of restricted subsidiaries; (vii) enter into sale and leaseback transactions; (viii) merge or consolidate with other entities; and (ix) enter into transactions with affiliates. In addition, the 2028 First Lien Notes Indenture requires, among other things, the Company to provide financial and current reports to holders of the 2028 First Lien Notes or file such reports electronically with the SEC. These covenants are subject to a number of exceptions, limitations and qualifications set forth in the Indenture, as well as suspension periods in certain circumstances.

In connection with the issuance of the 2025 Notes, the Company incurred approximately $8,779 of costs, which were deferred and are being amortized on the effective interest method over the term of the 2025 Notes.

The 2025 Notes are the Company's senior unsecured obligations and rank equally in right of payment with all of its other existing and future senior unsecured indebtedness and senior in right of payment to all of its existing and future subordinated indebtedness. The 2025 Notes are guaranteed on a full, joint and several basis by each of the Guarantor Subsidiaries.

The Company may redeem some or all of the 2025 Notes on or after August 15, 2020, at specified redemption prices.

The Company is obligated to offer to repurchase the 2025 Notes at a price of (i) 101% of their principal amount plus accrued and unpaid interest, if any, as a result of certain change-of-control events and (ii) 100% of their principal amount plus accrued and unpaid interest, if any, in the event of certain asset sales. These restrictions and prohibitions are subject to certain qualifications and exceptions.

The indenture governing the 2025 Notes (the "2025 Indenture") contains covenants that, among other things, limit the Company's ability and the ability of any of the guarantor subsidiaries to (i) grant liens on its assets, (ii) make dividend payments, other distributions or other restricted payments, (iii) incur restrictions on the ability of the Guarantor Subsidiaries to pay dividends or make other payments, (iv) enter into sale and leaseback transactions, (v) merge, consolidate, transfer or dispose of substantially all of their assets, (vi) incur additional indebtedness, (vii) use the proceeds from sales of assets, including capital stock of restricted subsidiaries, and (viii) enter into certain transactions with affiliates.

As disclosed in Note 2, as of March 31, 2023, the 2025 Notes are currently Designated Notes under the terms of the Warrant Agreement. Following the Warrants issuance on December 19, 2022, through March 31, 2023, $976 in principal amount of 2025 Notes were used to pay the exercise price for approximately 0.1 million Warrants, and resulting extinguishment losses from the write-off of deferred debt issuance costs were immaterial.

Financial Instruments Not Recorded at Fair Value

Carrying amounts and the related estimated fair values of the Company's long-term debt not recorded at fair value in the accompanying consolidated financial statements are as follows:

March 31, 2023				March 31, 2022
Carrying Value		Fair Value		Carrying Value		Fair Value
$	1,691,782	$	1,676,879	$	1,589,490	$	1,639,248

The fair value of the long-term debt was calculated based on either interest rates available for debt with terms and maturities similar to the Company's existing debt arrangements or broker quotes on its existing debt (Level 2 inputs).

Interest paid on indebtedness during the fiscal years ended March 31, 2023, 2022, and 2021, amounted to $138,464, $137,922 and $116,515, respectively. The Company also made redemption premium payments of approximately $26,157 and $9,108 in the years ended March 31, 2023 and 2022, respectively.

As of March 31, 2023, the fiscal year maturities of long-term debt are as follows: 2024 — $3,162; 2025 — $2,215; 2026 — $500,427; 2027 — $1,576; 2028 — $1,200,983; and thereafter— $5,477 through 2032.

The Company follows ASC 740, Income Taxes, which prescribes a recognition threshold and measurement attribute criteria for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return, as well as guidance on derecognition, classification, interest and penalties, disclosure and transition. The Company's policy is to release the tax effects from accumulated other comprehensive loss when all of the related assets or liabilities that gave rise to the accumulated other comprehensive loss (income) have been derecognized. The Company has elected to treat global intangible low-taxed income (“GILTI”) as a period expense.

A valuation allowance, if needed, reduces deferred tax assets to the amount expected to be realized. When determining the amount of net deferred tax assets that are more likely than not to be realized, the Company assesses all available positive and negative evidence. This evidence includes, but is not limited to, prior earnings history, expected future earnings, carry-back and carry-forward periods and the feasibility of ongoing tax strategies that could potentially enhance the likelihood of the realization of a deferred tax asset. The weight given to the positive and negative evidence is commensurate with the extent the evidence may be objectively verified. As such, it is generally difficult for positive evidence regarding projected future taxable income exclusive of reversing taxable temporary differences to outweigh objective negative evidence of recent financial reporting losses.

Based on these criteria and the relative weighting of both the positive and negative evidence available and, in particular, the activity surrounding the Company's prior earnings history, including the forward losses and intangible impairments previously recognized, management determined that it was necessary to establish a valuation allowance against principally all of its net deferred tax assets. Given the objective verifiable negative evidence of a three-year cumulative loss and the weighting of all available positive evidence, the Company excluded projected taxable income (aside from reversing taxable temporary differences) from the assessment of income that could be used as a source of taxable income to realize the deferred tax assets.

During fiscal year 2023, the Company adjusted the valuation allowance against the consolidated net deferred tax asset by $222 primarily due to an aggregate utilization of net operating loss carryforwards of approximately $146,354, utilization of capital loss carryforwards, and changes to temporary differences related to the impairment of long-lived intangible assets, interest disallowance, research and development cost amortization, and pension and other postretirement benefit plans. As of March 31, 2023, management determined that it was necessary to maintain a valuation allowance against principally all of its net deferred tax assets.

As of March 31, 2023, the Company has net operating loss carryforwards of $526,498, $1,433,276, and $136,646 for U.S. federal, state, and foreign jurisdictions, respectively. Approximately $65,020 of U.S. federal net operating losses begin to expire in 2038, and $461,478 have an indefinite carryforward period. State net operating losses begin to expire in 2024, with an immaterial portion classified as indefinite. Approximately $6,357 of foreign net operating losses begin to expire in 2027, and $130,289 have an indefinite carryforward period.

The effective income tax rate for the fiscal year ended March 31, 2023, was 6.4% as compared with (13.5)% for the fiscal year ended March 31, 2022. The effective income tax rate for the fiscal year ended March 31, 2023, included the benefit of the R&D tax credit of $2,234, and the change in the valuation allowance of $18,243. Due to the prior year pretax loss, the effective tax rate drivers on a percentage basis are amplified. Accordingly, a year-over-year comparison of the effective tax rate may not be indicative of changes in the Company's tax position.

The Company has been granted income tax holiday as an incentive to attract foreign investment by the Government of Thailand. The tax holidays continue to expire in various years through 2026. The Company does not have any other tax holidays in the jurisdictions in which it operates. The income tax benefit attributable to the tax status of our subsidiaries in Thailand was approximately $583 or $0.01 per diluted share in fiscal 2023, $415 or $0.01 per diluted share in fiscal 2022 and $0 or $0.00 per diluted share in fiscal 2021.

At March 31, 2023, cumulative undistributed earnings of foreign subsidiaries, for which no U.S. income or foreign withholding taxes have been recorded is $203,893. As the Company currently intends to indefinitely reinvest all such earnings, no provision has been made for income taxes that may become payable upon distribution of such earnings, and it is not practicable to determine the amount of the related unrecognized deferred income tax liability.

The Company has classified uncertain tax positions as noncurrent income tax liabilities unless expected to be paid in one year.

As of March 31, 2023 and 2022, the total amount of unrecognized tax benefits was $12,085 and $11,800, respectively, all of which would impact the effective rate, if recognized. The Company anticipates that total unrecognized tax benefits may be reduced by zero in the next 12 months. With a few exceptions, the Company is no longer subject to U.S. federal, state, or local income tax examinations, or foreign income tax examinations by tax authorities, for fiscal years ended before March 31, 2014.

As of March 31, 2023, the Company is not subject to any income tax examinations. The Company believes appropriate provisions for all outstanding issues have been made for all jurisdictions and all open years. There are no material interest and penalties accrued as of the year ended March 31, 2023.

A reconciliation of the liability for uncertain tax positions, which are included in deferred taxes for the fiscal years ended March 31, 2023, 2022, and 2021 follows:

Stockholders' Deficit

Stockholders' Deficit

13. STOCKHOLDERS' DEFICIT

In March 2022, the Company adopted a tax benefits preservation plan (the " Plan") designed to preserve Triumph’s ability to utilize its net operating loss carryforwards and other tax attributes (collectively, "Tax Benefits"). The Plan replaces a similar plan that was adopted in March 2019 and which expired in March 2022. The Company obtained stockholder approval for the Plan at its annual meeting of stockholders in July 2022.

Under the Plan, Triumph declared a dividend distribution of one right (a “Right”) for each share of its common stock outstanding at the close of business on March 21, 2022. The Plan will expire on March 13, 2025. The Rights also will expire: (i) if the Rights are redeemed or exchanged as provided in the Plan; (ii) if the Board determines that the Plan is no longer necessary or desirable for the preservation of the Tax Benefits; or (iii) if the Board determines that no Tax Benefits, once realized, as applicable, may be carried forward (in which case, the Rights will expire on the first date of the relevant taxable year for which such determination is made).

Pursuant to the Plan, if a stockholder (or group) becomes a 4.9% stockholder without meeting certain customary exceptions, the Rights become exercisable and entitle stockholders (other than the 4.9% stockholder or group causing the rights to become exercisable) to purchase additional shares of Triumph at a significant discount, resulting in significant dilution in the economic interest and voting power of the 4.9% stockholder or group causing the Rights to become exercisable. Stockholders owning 4.9% or more of Triumph’s outstanding shares at the time the Plan was adopted were grandfathered and will only cause the Rights to distribute and become exercisable if they acquire an additional one percent or more of Triumph’s outstanding shares. Under the Plan, the Board has the ability to determine in its sole discretion that any person shall not be deemed an acquiring person and therefore that the Rights shall not become exercisable if such person becomes a 4.9% stockholder. The adoption of the Plan and the dividend distribution did not have an impact on the Company’s consolidated financial statements.

On February 4, 2021, the Company implemented an “at the market” stock issuance program by entering into an Equity Distribution Agreement (the “Equity Distribution Agreement”) with Citigroup Global Markets Inc. (the “Manager”). Under the terms of the Equity Distribution Agreement, the Company may from time to time to or through the Manager, acting as agent and/or principal, offer and sell shares of its common stock having a gross sales price of up to $150,000. From the date the program was implemented through March 31, 2021, the Company completed the program, selling 9,178,752 shares with a gross sales price of $150,000 for total proceeds net of stock issuance costs of $145,383.

In 2014, the Company's Board of Directors authorized an increase in the Company's existing stock repurchase program by up to 5,000,000 shares of its common stock in addition to the 500,800 shares authorized under prior authorizations. As of March 31, 2023, the Company remains able to purchase an additional 2,277,789 shares. Repurchases may be made from time to time in open market transactions, block purchases, privately negotiated transactions or otherwise at prevailing prices. No time limit has been set for completion of the program.

The holders of the common stock are entitled to one vote per share on all matters to be voted upon by the stockholders of Triumph.

The Company has preferred stock of $0.01 par value, 250,000 shares authorized. At March 31, 2023 and 2022, zero shares of preferred stock were outstanding.

Earnings (Loss) per Share

Earnings Per Share [Abstract]

Earnings (Loss) per Share

14. EARNINGS (LOSS) PER SHARE

The calculation of basic earnings (loss) per share is based on the weighted average number of common shares considered outstanding during the periods. The calculation of diluted earnings per share reflects the effect of all potentially dilutive securities (principally outstanding warrants and outstanding restricted stock units). As disclosed in Note 2, the warrants permit the tendering of Designated Notes in payment of the exercise price. In computing diluted EPS, the Company applies the if-converted method to the warrants and such warrants are assumed to be exercised and the Designated Notes are assumed to be tendered unless tendering cash would be more advantageous to the warrant holder. Interest (net of tax) on any Designated Notes assumed to be tendered is added back as an adjustment to the numerator. The numerator also is adjusted for any nondiscretionary adjustments based on income (net of tax) including, for example, warrant remeasurement gains and losses recognized in the period. If cash exercise is more advantageous, the Company applies the treasury stock method to the warrants when calculating diluted EPS.

The following is a reconciliation between the weighted average common shares outstanding used in the calculation of basic and diluted earnings (loss) per share:

	Year ended March 31,

For the fiscal years ended March 31, 2023, 2022, and 2021, the shares that could potentially dilute earnings per share in the future but were not included in diluted weighted average common shares outstanding because to do so would have been anti-dilutive were immaterial.

Employee Benefit Plans

Retirement Benefits [Abstract]

Employee Benefit Plans

15. EMPLOYEE BENEFIT PLANS

Defined Contribution Pension Plan

The Company sponsors a defined contribution 401(k) plan, under which salaried and certain hourly employees may defer a portion of their compensation. Eligible participants may contribute to the plan up to the allowable amount as determined by the plan of their regular compensation before taxes. The Company generally matches contributions at a rate of 75% of the first 6% of compensation contributed by the participant. All contributions and Company matched contributions are invested at the direction of the employee in one or more investment options offered under the plan. Company matching contributions vest immediately and aggregated to $9,329, $2,998, and $1,665 for the fiscal years ended March 31, 2023, 2022, and 2021, respectively. Effective April 1, 2020, the Company suspended its 401(k) matching contribution for non-represented employees and some represented employees. This suspension was ended December 31, 2021, and the Company's 401(k) matching program recommenced effective January 1, 2022.

Defined Benefit Pension and Other Postretirement Benefit Plans

The Company sponsors several defined benefit pension plans covering some of its employees. Most current employees are ineligible to participate in the plans or have ceased to accrue additional benefits under the plans. Benefits under the defined benefit plans are based on years of service and, for most non-represented employees, on average compensation for certain years. It is the Company's policy to fund at least the minimum amount required for all qualified plans, using actuarial cost methods and assumptions acceptable under applicable government regulations, by making payments into a trust separate from us. The Company has in the past contributed and may in the future contribute shares of its common stock to this separate trust which would reduce the cash contribution required by the Company.

In addition to the defined benefit pension plans, the Company provides other postretirement benefits ("OPEB") in the form of certain health care benefits for eligible retired employees. Such benefits are unfunded as of March 31, 2023. The right to benefits under the current program ceased for all represented participants (actively employed and retired) by April 1, 2020. Company-funded notional health reimbursement accounts were provided to retired participants (and their dependents) whose eligibility for current benefits ended under the new agreement. As a result, the Company's OPEB liability is no longer material. Actuarial gains associated with the OPEB plan are carried within AOCI as shown in the table below.

In accordance with ASC 715, the Company has recognized the funded status of the benefit obligation as of March 31, 2023 and 2022, on the accompanying consolidated balance sheets. The funded status is measured as the difference between the fair value of the plans' assets and the PBO or accumulated postretirement benefit obligation of the plan. The plan assets are principally publicly traded investments which were valued based on the market price as of the measurement date. Investments that are not publicly traded were valued based on the estimated fair value of those investments based on the Company’s evaluation of data from fund managers and comparable market data.

The following tables set forth the Company's consolidated defined benefit pension plans for its union and non-union employees as of March 31, 2023 and 2022, and the amounts recorded on the consolidated balance sheets at March 31, 2023 and 2022. Company contributions include amounts contributed directly to plan assets and indirectly as benefits paid from the Company's assets. Benefit payments reflect the total benefits paid from the plans and the Company's assets. Information on the plans includes both the domestic qualified and nonqualified plans and the foreign qualified plans.

The Company recognized net periodic benefit income from its OPEB plan of approximately $9,163, $9,396, and $9,759 for the fiscal years ended March 31, 2023, 2022, and 2021, respectively.

The discount rate is determined annually as of each measurement date, based on a review of yield rates associated with long-term, high-quality corporate bonds. At the end of each year, the discount rate is primarily determined using the results of bond yield curve models based on a portfolio of high-quality bonds matching notional cash inflows with the expected benefit payments for each significant benefit plan.

The expected return on plan assets is determined based on a market-related value of assets ("MRVA"), which is a smoothed asset value. For fixed income securities, the MRVA is determined using the fair value of the fixed income assets. For all other classes of pension assets, the MRVA is calculated by recognizing investment performance that is different from that expected on a straight-line basis over five years. Actuarial gains and losses are amortized over the average remaining life expectancy of inactive participants for plans that are predominantly inactive and over the expected future service for active participants for other plans, but only to the extent unrecognized gains or losses exceed a corridor equal to 10% of the greater of the projected benefit obligation or market-related value of assets.

The Company estimates the service and interest cost of its pension and OPEB plans by using the specific spot rates derived from the yield curve used to discount the cash flows reflected in the measurement of the benefit obligation. The Company believes this approach provides a precise measurement of service and interest costs due to the correlation between projected benefit cash flows to the corresponding spot yield curve rates.

During the fiscal year ended March 31, 2023, the Society of Actuaries did not release a new mortality projection scale, and therefore the mortality projection scale remains unchanged. The Company did reflect an adjustment to the base mortality table for a subset of participants based on its review of actual mortality experience in the measurement of its U.S. pension plan as of March 31, 2023. This change resulted in an increase in the benefit obligation.

The projected benefit obligation assumptions impacting net actuarial gain consist of changes in discount and mortality rates, as well as changes in plan experience.

The Company periodically experiences events or makes changes to its benefit plans that result in curtailment or special charges. Curtailments are recognized when events occur that significantly reduce the expected years of future service of present employees or eliminates the benefits for a significant number of employees for some or all of their future service.

Curtailment losses are recognized when it is probable the curtailment will occur and the effects are reasonably estimable. Curtailment gains are recognized when the related employees are terminated or a plan amendment is adopted, whichever is applicable.

As required under ASC 715, the Company remeasures plan assets and obligations during an interim period whenever a significant event occurs that results in a material change in the net periodic pension cost. The determination of significance is based on judgment and consideration of events and circumstances impacting the pension costs.

The following summarizes the key events whose effects on net periodic benefit cost and obligations are included in the tables above:

•On March 21, 2022, the Company elected to purchase annuities and settle the pension obligations for approximately 2,500 retired participants in its qualified U.S. pension plan. As a result of this transaction approximately $52,256 of plan assets and $51,418 of plan liabilities were transferred to the Nationwide Life and Annuity Insurance Company. The settlement resulted in the recognition of prior noncash actuarial losses of approximately $32,116 in the year ended March 31, 2022. The settlement's impact on the accompanying consolidated balance sheets was insignificant as the plan's assets were materially consistent with the settled pension obligation.

•Effective August 31, 2021, the Company settled the fully-funded pension obligation it had retained subsequent to its fiscal year 2019 divestiture of Triumph Geared Solutions - Toronto. The settlement resulted in the recognition of prior noncash actuarial losses of approximately $3,826 in the year ended March 31, 2022. The settlement's impact on the accompanying consolidated balance sheets was insignificant as the plan's assets were materially consistent with the settled pension obligation.

•Upon the completion of the sale of the composites and large structure manufacturing operations as disclosed in Note 3, the expected future service of certain defined benefit pension plan participants was curtailed and certain participants became eligible for subsidized early retirement benefits under the terms of the relevant plan. As a result, the Company performed an interim remeasurement and recognized a onetime pension curtailment charge of approximately $16,024 which is presented in non-service defined benefit income on the accompanying condensed consolidated statement of operations for year ended March 31, 2022.

Additionally, the Company accrued a Withdrawal Liability (as defined below), and recognized in non-serviced defined benefit income, of $14,644 as a result of the exit of its Spokane, Washington, composites manufacturing operations in the year ended March 31, 2023. Refer to Note 17 for further information.

Expected Pension Benefit Payments

The total estimated future benefit payments for the pension plans are expected to be paid from the plan assets and company funds. The OPEB payments reflect the Company's portion of the funding. Estimated future benefit payments from plan assets and Company funds for the next ten years are as follows:

Year	Pension Benefits
2024	$	165,443
2025		150,139
2026		144,837
2027		140,333
2028		135,495
2029 - 2033		614,559

Plan Assets, Investment Policy and Strategy

The table below sets forth the Company's target asset allocation for fiscal 2023 and the actual asset allocations at March 31, 2023 and 2022.

Pension plan assets are invested in various asset classes that are expected to produce a sufficient level of diversification and investment return over the long-term. The investment goals are to exceed the assumed actuarial rate of return over the long-term within reasonable and prudent levels of risks and to meet future obligations.

Asset/liability studies are conducted on a regular basis to provide guidance in setting investment goals for the pension portfolio and its asset allocation. The asset allocation aims to prudently achieve a strong, risk-adjusted return while seeking to minimize funding level volatility and improve the funded status of the plans. The pension plans currently employ a liability-driven investment ("LDI") approach, where assets and liabilities move in the same direction. The goal is to limit the volatility of the funding status and cover part, but not all, of the changes in liabilities. Most of the liabilities' changes are due to interest rate movements.

To balance expected risk and return, allocation targets are established and monitored against acceptable ranges. All investment policies and procedures are designed to ensure that the plans' investments are in compliance with the Employee Retirement Income Security Act of 1974 ("ERISA"). Guidelines are established defining permitted investments within each asset class. Each investment manager has contractual guidelines to ensure that investments are made within the parameters of their asset class or in the case of multi-asset class managers, the parameters of their multi-asset class strategy. Certain investments are not permitted at any time, including investment directly in employer securities and uncovered short sales.

The tables below provide the fair values of the Company's plan assets at March 31, 2023 and 2022, by asset category. The table also identifies the level of inputs used to determine the fair value of assets in each category (refer to Note 2 for definition of levels).

Cash equivalents and other short-term investments are primarily held in registered short-term investment vehicles which are valued using a market approach based on quoted market prices of similar instruments.

Public equity securities, including common stock, are primarily valued using a market approach based on the closing fair market prices of identical instruments in the principal market on which they are traded. Commingled funds that are open-ended mutual funds for which the fair value per share is determined and published by the respective mutual fund sponsor and is the basis for current observable transactions are categorized as Level 1 fair value measures.

Investments in commingled funds and private equity and infrastructure funds are carried at net asset value ("NAV") as a practical expedient to estimate fair value. The NAV is the total value of the fund divided by the number of shares outstanding. Adjustments to NAV, if any, are determined based on evaluation of data provided by fund managers, including valuation of the underlying investments derived using inputs such as cost, operating results, discounted future cash flows and market-based comparable data. In accordance with ASC 820-10, investments that are measured at NAV practical expedient are not classified in the fair value hierarchy; however, their fair value amounts are presented in these tables to permit reconciliation of the fair value hierarchy to the total plan assets disclosed in this footnote.

Corporate, government agency bonds and mortgage-backed securities are primarily valued using a market approach with inputs that include broker quotes, benchmark yields, base spreads and reported observable trades for identical or comparable instruments.

Other investments include insurance contracts primarily valued based on estimates of the premium required to acquire similar insurance contracts using market-based comparable data.

Assumptions and Sensitivities

The discount rate is determined as of each measurement date, based on a review of yield rates associated with long-term, high-quality corporate bonds. The calculation separately discounts benefit payments using the spot rates from a long-term, high-quality corporate bond yield curve.

The effect of a 25 basis-point change in discount rates as of March 31, 2023, is shown below:

		Pension Benefits
Increase of 25 basis points
Obligation	*	$	(34,222	)
Net periodic expense			176
Decrease of 25 basis points
Obligation	*	$	35,567
Net periodic expense			(204	)

* Excludes impact to plan assets due to the LDI investment approach discussed above under "Plan Assets, Investment Policy and Strategy."

The long-term rate of return assumption represents the expected average rate of earnings on the funds invested to provide for the benefits included in the benefit obligations. The long-term rate of return assumption is determined based on a number of factors, including historical market index returns, the anticipated long-term asset allocation of the plans, historical plan return data, plan expenses and the potential to outperform market index returns. For fiscal 2024, the expected long-term rate of return is 5.75% - 8.00%.

Anticipated Contributions to Defined Benefit

The Company expects to contribute approximately $14,700 to its qualified U.S. defined benefit pension plans during fiscal 2024. No plan assets are expected to be returned to the Company in fiscal 2024.

Share-Based Payment Arrangement [Abstract]

Stock Compensation Plans

16. STOCK COMPENSATION PLANS

The Company has stock incentive plans under which employees and non-employee directors may be granted equity awards in the form of stock options with an exercise price equal to the fair value of the Company’s stock on the grant date or in the form of restricted stock or restricted stock units that vest pursuant to service conditions and, in some cases, performance or market conditions. The stock incentive and compensation plans under which outstanding equity awards have been granted to employees, officers, and non-employee directors are the Triumph Group 2018 Equity Plan (the "2018 Plan"), the Triumph Group 2013 Equity and Cash Incentive Plan (the “2013 Plan”), the 2016 Directors’ Equity Compensation Plan, as amended (the “Directors’ Plan”), and the Amended and Restated Directors’ Stock Incentive Plan (the “Prior Directors’ Plan”). The Prior Directors’ Plan expired by its terms during fiscal 2017. The current stock incentive and compensation plans used for future awards are the 2018 Plan and the Directors’ Plan. New grants under the 2013 Plan ceased upon the approval of the 2018 Plan in fiscal 2019, and the 2013 Plan will formally expire by its terms during fiscal 2024. The 2018 Plan and the Directors’ Plan are collectively referred to in this note as the plans.

Management and the compensation committee have utilized restricted stock and restricted stock units as its primary form of share-based incentive compensation. Restricted stock and restricted stock units that vest solely pursuant to service conditions generally vest on a graded basis over a three year period and are subject to forfeiture should the grantee’s employment be terminated prior to an applicable vesting date. Management and the compensation committee have also granted restricted stock and restricted stock units, referred to herein as performance restricted stock awards, that vest pursuant to a combination of service conditions as well as market and performance conditions. Such awards may vest, subject to specific market or performance conditions, on a cliff vesting basis at the end of a three year performance period, on a graded basis over discrete performance periods over three year period, or a combination of thereof. The market and performance conditions may result in the awards vesting below target, including zero vesting awards if certain threshold vesting conditions are not met, or up to 300% of the number of awards granted, if certain vesting conditions are exceeded. The share-based payment expense arising from restricted stock and restricted stock unit expense is included in capital in excess of par value. The fair value of restricted stock or restricted stock units awards subject only to service conditions or service and performance conditions is determined by the product of the number of shares granted and the grant date market price of the Company's common stock, adjusted for material non-public information that the Company may be aware of as of the grant date, if any. The fair value of restricted stock or restricted stock units awards that contain market conditions is determined by the product of the number of shares granted and the grant date fair value of such an award value using a Monte Carlo valuation methodology. The fair value of share-based

compensation granted to employees was $13,728, $14,129, and $13,103 during the fiscal years ended March 31, 2023, 2022, and 2021, respectively. The fair value of restricted stock and restricted stock unit awards is expensed on a straight-line basis over the requisite service period which is typically the vesting period. The Company recognized $8,913, $9,782 and $12,701 of share-based compensation expense during the fiscal years ended March 31, 2023, 2022, and 2021, respectively. The Company has classified share-based compensation within selling, general and administrative expenses to correspond with the same line item as the majority of the cash compensation paid to the employees receiving share-based compensation.

At March 31, 2023 and 2022, 979,855 shares and 1,706,634 shares of common stock, respectively, were available for issuance under the plans. A summary of the status of the Company's non-vested shares/units of restricted stock and deferred stock units as of March 31, 2023, and changes during the fiscal year ended March 31, 2023, is presented below.

	Shares			Weighted- Average Grant Date Fair Value
Non-vested restricted awards and deferred stock units at March 31, 2022		1,361,155		$	18.00
Granted		954,949			14.38
Vested		(561,862	)		16.46
Forfeited		(241,046	)		19.73
Non-vested restricted awards and deferred stock units at March 31, 2023		1,513,196		$	16.01

The fair value of employee restricted stock and restricted stock units which vested during fiscal 2023, 2022 and 2021 was $9,247, $7,453, and $8,037, respectively. Expected future compensation expense on restricted stock units, net of expected forfeitures, is approximately $11,626, which is expected to be recognized over the remaining weighted average vesting period of approximately 1.5 years.

Commitments And Contingencies [Abstract]

Commitments and Contingencies

17. COMMITMENTS AND CONTINGENCIES

Environmental Matters

Certain of the Company's business operations and facilities are subject to a number of federal, state, local and foreign environmental laws and regulations. Former owners generally indemnify the Company for environmental liabilities related to the assets and businesses acquired which existed prior to the acquisition dates. In the opinion of management, there are no significant environmental contingent liabilities which would have a material effect on the financial condition or operating results of the Company which are not covered by such indemnification.

Commercial Disputes and Litigation

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

In the ordinary course of business, the Company is involved in disputes, claims and lawsuits with employees, suppliers and customers, as well as governmental and regulatory inquiries, that it deems to be immaterial. Some may involve claims or potential claims of substantial damages, fines, penalties or injunctive relief. While the Company cannot predict the outcome of any pending or future litigation or proceeding and no assurances can be given, the Company does not believe that any pending matter will have a material effect, individually or in the aggregate, on its financial position or results of operations.

Divestitures, Disposals, Guarantees, and Indemnifications

As disclosed in Note 3, we have engaged in a number of divestitures. In connection with divestitures and related transactions, the Company from time to time has indemnified and has been indemnified by third parties against certain liabilities that may arise in connection with, among other things, business activities prior to the completion of the respective transactions. The term of these indemnifications, which typically pertain to environmental, tax and product liabilities, is generally indefinite. As of March 31, 2023, no indemnification assets or liabilities have been recorded.

As it relates to certain divestitures, disputes have arisen or may continue to arise between the Company and the acquirer subsequent to the completion and closing of the divestiture transaction. Such disputes have included or may include amounts payable to or from the buyer for closing working capital adjustments to the purchase price as well as claims regarding alleged violations of contractual terms, representations, and warranties of the sale agreements, among other matters. The outcome of such disputes typically involve negotiations between the Company and the acquirer, but could also lead to litigation between the parties, and the ultimate claims made by the parties against each other could be material. As of March 31, 2023, we have

accrued for our estimate of probable losses associated with such disputes, but losses in excess of those currently accrued could be incurred and may be material. The Company has received notification of claims which allege certain bases for indemnification and damages relating to certain divestitures, including a May 17, 2023, letter relating to the sale of the Stuart facility. The relevant agreements generally contain limits on certain damages that may be payable under the relevant agreements. For example, the divestiture agreement relating to the sale of the Stuart facility contains an $18,750 general cap on breaches of representations (other than certain specified representations) and a $25,000 cap on breaches of certain specified representations related to contracts and product warranties, in each case absent certain circumstances, including fraud or breaches of fundamental or tax representations. While the Company cannot predict the outcome of any pending or future litigation, proceeding, or claim and no assurances can be given, the Company intends to vigorously defend claims brought against it and does not believe that any pending matter will have a material effect, individually or in the aggregate, on its financial position or results of operations. If the Company is unable to successfully and equitably resolve such claims and assertions, its business, financial condition, and results of operations could be materially adversely affected.

Additionally, in connection with certain divestitures, the Company has obtained customer consent to assign specified long-term contracts to the acquirer of the divested business by entering into consent-to-assignment agreements among the customer, the acquirer, and the Company. Pursuant to certain of these agreements, the Company remains a co-obligor under the contract pursuant to guarantee agreements with the customer that predate the divestiture transaction. The term of these obligations typically covers a period of 2 to 5 years from the date of divestiture. There is no limitation to the maximum potential future liabilities under these contracts; however, the Company is typically indemnified by acquirers against such losses that may arise from the acquirers’ failure to perform under the assigned contracts. As of March 31, 2023, no related indemnification assets or liabilities or guarantee liabilities have been recorded, and the Company has not been called upon to act as co-obligor under such arrangements through that date. Also, in connection with certain divestitures, the Company has assigned lease facility lease agreements to the acquirers and entered into agreements to act as a co-obligor under the lease agreement in the event of non-performance under the lease by the assignee. The Company is generally indemnified by the assignee or other third party to the transaction. On May 2, 2023, the Company received a letter from a lessor associated with one such transaction to assert the lessor’s rights against the Company as guarantor. The lease payment associated with the lease is approximately $130 per month over a lease term ending December 31, 2031, although the landlord has acknowledged its duty to mitigate damages by re-leasing the property. The Company expects to be fully indemnified for any amounts payable under such guarantee.

As the Company has completed the disposal of certain facilities, it may be exposed to additional costs such as environmental remediation obligations, lease termination costs, or customer or supplier claims which may have a material effect on its financial position or results of operations when such matters arise and a reasonable estimate of the costs can be made. For example, in the year ended March 31, 2023, the Company withdrew from the IAM National Pension Fund (the “Fund), which is a multiemployer pension plan to which the Company previously contributed on behalf of certain of its represented employees. Such withdrawal occurred as part of the Company’s exit of its Spokane, Washington, composites manufacturing operations. In April 2023, the Company received a letter from the Fund confirming the Company’s complete withdrawal from the Fund and indicating that the Company’s portion of the unfunded vested benefits (the “Withdrawal Liability”) was estimated to be approximately $14,644, payable in quarterly installments of approximately $400 over a period of approximately thirteen years. The Withdrawal Liability is subject to further adjustment based on the finalization of the Fund’s actuarial valuation for the plan year ending December 31, 2021, (i.e., the applicable plan year preceding the date of the Company’s withdrawal). The Company has accrued a liability of $14,644, on the accompanying consolidated balance sheet as of March 31, 2023, representing its estimate of the obligation based on the letter received from the Fund. The Company is in the process of reviewing and responding to the withdrawal liability assessment, and it is possible the Withdrawal Liability could be reduced during that process.

Customer Concentration

18. CUSTOMER CONCENTRATION

Trade and other receivables from The Boeing Company ("Boeing") represented approximately 12% and 17% of total trade and other receivables as of March 31, 2023 and 2022, respectively. Trade and other receivables from Daher Aerospace Inc. ("Daher") include receivables that largely correspond with payables associated with transition services and represented approximately 20% as of March 31, 2023. The Company has a right to collect such receivables from Daher when the related trade payable is paid by the Company. The transition services agreement with Daher is set to contractually expire on June 30, 2023. Trade and other accounts receivable from Daher were not significant as of March 31, 2022. The Company had no other significant concentrations of credit risk.

Sales to Boeing for fiscal 2023 were $296,132, or 21% of net sales, of which $191,193 and $104,939 were from Systems & Support and Interiors (formerly Aerospace Structures), respectively. Sales to Boeing for fiscal 2022 were $491,606, or 34% of net sales, of which $157,686 and $333,920 were from Systems & Support and Interiors (formerly Aerospace Structures), respectively.

Sales to Boeing for fiscal 2021 were $698,372, or 37% of net sales, of which $225,027 and $473,346 were from Systems & Support and Interiors (formerly Aerospace Structures), respectively.

No other single customer accounted for more than 10% of the Company's net sales; however, the loss of any significant customer, including Boeing, could have a material adverse effect on the Company and its operating subsidiaries.

The Company currently generates a majority of its revenue from clients in the commercial aerospace industry and the military. The Company's growth and financial results are largely dependent on continued demand for its products and services from clients in these industries. When these industries experience a downturn, it is possible that customers in these sectors may conduct less business with the Company.

Segments

20. SEGMENTS

The Company reports financial performance based on the following two reportable segments: Systems & Support and Interiors (formerly Aerospace Structures). The Company’s reportable segments are aligned with how the business is managed, and the Company's views of the markets it serves. The Chief Operating Decision Maker (the "CODM") evaluates performance and allocates resources based upon review of segment information. The CODM utilizes earnings before interest, income taxes, consideration payable to customer related to divestiture, depreciation and amortization, and pension (“Adjusted EBITDAP”) as a primary measure of segment profitability to evaluate the performance of its segments and allocate resources.

Segment Adjusted EBITDAP is total segment revenue reduced by operating expenses (less depreciation and amortization) identifiable with that segment. Corporate includes general corporate administrative costs and any other costs not identifiable with one of the Company’s segments.

The Company does not accumulate net sales information by product or service or groups of similar products and services, and therefore the Company does not disclose net sales by product or service because to do so would be impracticable.

Selected financial information for each reportable segment is as follows:

Accounting Policies [Abstract]

Cash and Cash Equivalents

Cash and Cash Equivalents

Cash equivalents consist of highly liquid investments with a maturity of three months or less at the time of purchase. Fair value of cash equivalents approximates carrying value.

Trade and Other Receivables, net

Trade and Other Receivables, net

Trade and other receivables are recorded net of an allowance for expected credit losses. Trade and other receivables include amounts billed and currently due from customers and amounts retained by the customer pending contract completion. The Company performs ongoing credit evaluations of its customers and generally does not require collateral. The Company pools receivables that share underlying risk characteristics and records the allowance for expected credit losses based on a combination of prior experience, current economic conditions and management’s expectations of future economic conditions, and specific collectibility matters when they arise. The Company writes off balances against the allowance for expected credit losses when collectibility is deemed remote. The Company's trade and other receivables are exposed to credit risk; however, the risk is limited due to the diversity of the customer base. For the years ended March 31, 2023 and 2022, credit loss expense and write-offs were immaterial.

Trade and other receivables, net composed of the following:

Goodwill and Intangible Assets

Goodwill and Intangible Assets

The Company accounts for goodwill and intangible assets in accordance with ASC 350, Intangibles—Goodwill and Other. Under ASC 350, goodwill and intangible assets with indefinite lives are not amortized; rather, they are tested for impairment on at least an annual basis. Intangible assets with finite lives are amortized over their useful lives.

The Company assesses whether goodwill impairment exists using both the qualitative and quantitative assessments. The qualitative assessment involves determining whether events or circumstances exist that indicate it is more likely than not that the fair value of a reporting unit is less than its carrying amount, including goodwill. If based on this qualitative assessment the Company determines it is more likely than not that the fair value of a reporting unit is less than its carrying amount or if the Company elects not to perform a qualitative assessment, a quantitative assessment is performed as required by ASC 350 to determine whether a goodwill impairment exists at the reporting unit.

The quantitative test is used to compare the carrying amount of the reporting unit's assets to the fair value of the reporting unit. If the fair value exceeds the carrying value, no further evaluation is required, and no impairment loss is recognized. If the carrying amount exceeds the fair value, then an impairment loss occurs. The impairment is measured by using the amount by which the carrying value exceeds the fair value not to exceed the amount of recorded goodwill. The determination of the fair value of its reporting units is based, among other things, on estimates of future operating performance of the reporting unit being valued. The Company is required to complete an impairment test for goodwill and record any resulting impairment losses at least annually. Changes in market conditions, among other factors, may have an impact on these estimates and require interim impairment assessments.

When performing the quantitative impairment test, the Company's methodology includes the use of an income approach which discounts future net cash flows to their present value at a rate that reflects the Company's cost of capital, otherwise known as the discounted cash flow method ("DCF"). These estimated fair values are based on estimates of future cash flows of the businesses. Factors affecting these future cash flows include the continued market acceptance of the products and services offered by the businesses, the development of new products and services by the businesses and the underlying cost of development, the future cost structure of the businesses and future technological changes. The Company also incorporates market multiples for comparable companies in determining the fair value of its reporting units. Any such impairment would be recognized in full in the reporting period in which it has been identified. The fair value estimates resulting from the application of these methodologies are based on inputs classified within Level 3 of the fair value hierarchy, as described below.

During the fourth quarter of the fiscal years ended March 31, 2023 and 2022, the Company performed its annual goodwill impairment assessment for each of its reporting units with no impairment identified.

Finite-lived intangible assets are amortized over their useful lives ranging from 10 to 30 years. The Company continually evaluates whether events or circumstances have occurred that would indicate that the remaining estimated useful lives of long-lived assets, including intangible assets, may warrant revision or that the remaining balance may not be recoverable. Long-lived assets are evaluated for indicators of impairment. When factors indicate that long-lived assets, including intangible assets, should be evaluated for possible impairment, an estimate of the related undiscounted cash flows over the remaining life of the long-lived assets, including intangible assets, is used to measure recoverability based on the primary asset of the asset group. Some of the more important factors management considers include the Company's financial performance relative to expected and historical performance, significant changes in the way the Company manages its operations, negative events that have occurred, and negative industry and economic trends. If the estimated undiscounted cash flows are less than the carrying amount, measurement of the impairment will be based on the difference between the carrying value and fair value of the asset group, generally determined based on the present value of expected future cash flows associated with the use of the asset.

In fiscal 2021, the Company's Board of Directors committed to a plan (i) to sell its composites manufacturing operations located in Milledgeville, Georgia, and Rayong, Thailand, and (ii) to transfer the assets and certain liabilities associated with its Gulfstream G650 wing supply chain activities (as disclosed in Note 3, this transaction closed in August 2020). These planned divestitures

represented the divestiture of certain assets and liabilities of an operating business within the Interiors (formerly Aerospace Structures) segment that the Company had identified as an asset group pursuant to the provisions of ASC 360, Property, Plant, and Equipment. As a result, as of May 31, 2020, the Company concluded that the planned divestitures represented a significant change in the manner in which the related asset group was expected to be used, and that the asset group therefore needed to be tested for recoverability. The asset group primarily consisted of working capital, fixed assets and definite-lived intangible assets. The Company first determined that the relevant long-lived asset group was not recoverable by comparing the undiscounted cash flows expected to be generated by the long-lived asset group to the carrying value of the asset group. As a result, the Company estimated the fair value of the long-lived asset group and concluded that the asset group was impaired. The Company used a multi-period excess earnings approach to estimate the fair value of the long-lived asset group for purposes of testing the asset group for impairment. This method estimates fair value based on the expected future excess earnings stream attributable to the asset group. This method requires the use of several key assumptions, including revenue projections that consider historical and estimated future results, general economic and market conditions, as well as the impact of planned business and operational strategies. A discount rate of 15.0% was applied to the estimated future excess earnings and cash flows in order to estimate the fair value of the asset group as of the measurement date. The Company has determined that the lowest level of the inputs that are significant to the fair value measurement are unobservable inputs that fall within Level 3 of the fair value hierarchy.

In accordance with ASC 360, the Company allocated the resulting impairment to the specific long-lived assets within the asset group on a pro rata basis, except that the loss allocated to an individual long-lived asset of the group did not reduce the carrying amount of that asset below its estimated fair value. As a result, the Company recognized a total noncash impairment charge of $252,382 in the first quarter, primarily allocated to definite-lived intangible assets, which is presented as “Impairment of long-lived assets” on the accompanying consolidated statements of operations. In January 2021, the Company’s Board of Directors committed to a plan to sell its manufacturing operations located in Red Oak, Texas. As a result of this decision and the resulting classification of this disposal group as held for sale, the Company fully impaired the remaining customer relationship intangible asset within the Interiors (formerly Aerospace Structures) segment and recognized a noncash impairment charge of $6,696, which has been included in the impairment on the assets held for sale as disclosed in Note 3 and is presented within “(Gain) loss on sale of assets and businesses” on the accompanying consolidated statement of operations.

See below for the Company's accounting policy regarding fair value measurements and the definition of fair value levels.

Revenue Recognition and Contract Balances

Revenue Recognition and Contract Balances

The Company's revenue is principally from contracts with customers to provide design, development, manufacturing, and support services associated with specific customer programs. The Company regularly enters into long-term master supply agreements that establish general terms and conditions and may define specific program requirements. Many agreements include clauses that provide sole supplier status to the Company for the duration of the program’s life. Purchase orders (or authorizations to proceed) are issued pursuant to the master supply agreements. Additionally, a majority of the Company’s agreements with customers include options for future purchases. Such options primarily reduce the administrative effort of issuing subsequent purchase orders and do not represent material rights granted to customers. The Company generally enters into agreements directly with its customers and is the principal in all current contracts.

The identification of a contract with a customer for purposes of accounting and financial reporting requires an evaluation of the terms and conditions of agreements to determine whether presently enforceable rights and obligations exist. Management considers a number of factors when making this evaluation that include, but are not limited to, the nature and substance of the business exchange, the specific contractual terms and conditions, the promised products and services, the termination provisions in the contract, as well as the nature and execution of the customer’s ordering process and how the Company is authorized to perform work. Generally, presently enforceable rights and obligations are not created until a purchase order is issued by a customer for a specified number of units of product or services. Therefore, the issuance of a purchase order is generally the point at which a contract is identified for accounting and financial reporting purposes.

Management identifies the promises to the customer. Promises are generally explicitly stated in each contract, but management also evaluates whether any promises are implied based on the terms of the agreement, past business practice, or other facts and circumstances. Each promise is evaluated to determine if it is a performance obligation. A performance obligation is a promise in a contract to transfer a distinct good or service. The Company considers a number of factors when determining whether a promise is a distinct performance obligation, including whether the customer can benefit from the good or service on its own or together with other resources that are readily available to the customer, whether the Company provides a significant service of integrating goods or services to deliver a combined output to the customer, or whether the goods or services are highly interdependent. The Company’s performance obligations consist of a wide range of engineering design services and manufactured components, as well as spare parts and repairs for OEMs.

The transaction price for a contract reflects the consideration the Company expects to receive for fully satisfying the performance obligations in the contract. Typically, the transaction price consists solely of fixed consideration but may include variable consideration for contractual provisions such as unpriced contract modifications, cost-sharing provisions, and other receipts or payments to customers. The Company identifies and estimates variable consideration, typically at the most likely amount the Company expects to receive from its customers. Variable consideration is only included in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized for the contract will not occur, or when the uncertainty associated with the variable consideration is resolved. Consideration paid or payable to a customer is reflected as a reduction in net revenues when the amounts paid are not related to a distinct good or service at the later of when the related revenue is recognized or when the Company pays or promises to pay the consideration to the customer. The Company's contracts with customers generally require payment under normal commercial terms after delivery with payment typically required within 30 to 120 days of delivery.

The Company generally is not subject to collecting sales tax and has made an accounting policy election to exclude from the transaction price any sales and other similar taxes collected from customers. As a result, any such collections are accounted for on a net basis.

The total transaction price is allocated to each of the identified performance obligations using the relative stand-alone selling price. The objective of the allocation is to reflect the consideration that the Company expects to receive in exchange for the products or services associated with each performance obligation. Stand-alone selling price is the price at which the Company would sell a promised good or service separately to a customer. Stand-alone selling prices are established at contract inception, and subsequent changes in transaction price are allocated on the same basis as at contract inception. When stand-alone selling prices for the Company’s products and services are not observable, the Company uses either the “Expected Cost Plus a Margin” or "Adjusted Market Assessment" approaches to estimate stand-alone selling price. Expected costs are typically derived from the available periodic forecast information.

Revenue is recognized when or as control of promised products or services transfers to a customer and is recognized at the amount allocated to each performance obligation associated with the transferred products or services. Service sales, principally representing repair, maintenance, and engineering activities are recognized over the contractual period or as services are rendered. Sales under long-term contracts with performance obligations satisfied over time are recognized using either an input or output method. The Company recognizes revenue over time as it performs on these contracts because of the continuous transfer of control to the customer as represented by contractual terms that entitle the Company to the reimbursement of costs plus a reasonable profit for work performed to manufacture products for which the Company has no alternate use or for work performed on a customer-owned asset.

With control transferring over time, revenue is recognized based on the extent of progress toward completion of the performance obligation. The Company generally uses the cost-to-cost input method of progress for its contracts because it best depicts the transfer of control to the customer that occurs as work progresses. Under the cost-to-cost method, the extent of progress toward completion is measured based on the proportion of costs incurred to date to the total estimated costs at completion of the performance obligation. The Company reviews its cost estimates on contracts on a periodic basis, or when circumstances change and warrant a modification to a previous estimate. Cost estimates are largely based on negotiated or estimated purchase contract terms, historical performance trends and other economic projections. Significant factors that influence these estimates include inflationary trends, technical and schedule risk, internal and subcontractor performance trends, business volume assumptions, asset utilization, and anticipated labor agreements.

Revenue and cost estimates are regularly monitored and revised based on changes in circumstances. Impacts from changes in estimates of net sales and cost of sales are recognized on a cumulative catch-up basis, which recognizes in the current period the cumulative effect of the changes on current and prior periods based on a performance obligation’s percentage of completion. Forward loss reserves for anticipated losses on long-term contracts are recorded in full when such losses become evident, to the extent required and are included in contract liabilities on the accompanying consolidated balance sheets. The Company believes

that the accounting estimates and assumptions made by management are appropriate, however actual results could differ materially from those estimates.

For the fiscal year ended March 31, 2023, cumulative catch-up adjustments resulting from changes in contract values and estimated costs that arose during the fiscal year increased revenue, operating income, net income, and diluted earnings per share by approximately $21,208, $27,963, $27,963, and $0.39, respectively. The cumulative catch-up adjustments to operating income for the fiscal year ended March 31, 2023, included gross favorable adjustments of approximately $32,699 and gross unfavorable adjustments of approximately $4,736.

For the fiscal year ended March 31, 2022, cumulative catch-up adjustments resulting from changes in estimates increased revenue and decreased operating loss, net loss, and diluted loss per share by approximately $6,884, $16,042, $16,042, and $0.25, respectively. The cumulative catch-up adjustments to operating income for the fiscal year ended March 31, 2022, included gross favorable adjustments of approximately $30,560 and gross unfavorable adjustments of approximately $14,518.

For the fiscal year ended March 31, 2021, cumulative catch-up adjustments resulting from changes in estimates increased revenue and decreased operating loss, net loss, and diluted loss per share by approximately $4,796, $12,332, $12,332, and $0.23, respectively. The cumulative catch-up adjustments to operating income for the fiscal year ended March 31, 2021, included gross favorable adjustments of approximately $55,180 and gross unfavorable adjustments of approximately $42,848.

Revenues for performance obligations that are not recognized over time are recognized at the point in time when control transfers to the customer. For performance obligations that are satisfied at a point in time, the Company evaluates the point in time when the customer can direct the use of and obtain the benefits from the products and services. Generally, the shipping terms determine the point in time when control transfers to customers. Shipping and handling activities are not considered performance obligations and related costs are included in cost of sales as incurred.

Differences in the timing of revenue recognition and contractual billing and payment terms result in the recognition contract assets and liabilities. Refer to Note 4 for further discussion.

Warrants

Warrants

On December 1, 2022, the Company’s board of directors declared a distribution to holders of the Company’s shares of common stock in the form of warrants to purchase shares of common stock (the “Warrants”). Holders of common stock received three Warrants for every ten shares of common stock held as of December 12, 2022 (the "Record Date") (rounded down for any fractional warrant). The Company issued approximately 19.5 million Warrants on December 19, 2022, to holders of record of common stock as of the close of business on the Record Date. The Warrants trade on the over-the-counter market.

Each Warrant represents the right to purchase initially one share of common stock, subject to certain anti-dilution adjustments (“Warrant Shares Per Warrant”), at an exercise price of $12.35 per Warrant (the “Exercise Price”), subject to certain anti-dilution adjustments (the “Implied Per Share Exercise Price”). Payment for shares of common stock on exercise of Warrants may be in (i) cash or (ii) under certain circumstances, Designated Notes (as defined below). In the event Designated Notes are used to pay for the exercise of the Warrants, accrued interest (in addition to the stated aggregate principal amount) will be forfeited upon exercise, unless exercise occurs after a record date for the payment of interest and before the resulting scheduled payment date (in which case note holders will receive the scheduled interest payment). If all Warrants were exercised and settled as of March 31, 2023, the Company would be required to issue approximately 19.1 million shares (assuming no over-exercise options, as described below, were exercised). The closing price of the Company’s shares of common stock was $11.59 as of March 31, 2023.

“Designated Notes” means, collectively, any of the issued and outstanding notes of the Company as designated or undesignated by the Company from time to time; provided that any designation by the Company of a particular series of notes as “Designated Notes” shall retain such designation for a minimum of 20 consecutive business days from (and including) the date of publication of notice of the same by press release. The Company also has the right, but not obligation, to remove one or more series of its notes from being “Designated Notes,” but such redesignation shall only be effective 20 consecutive business days from (and including) the date of publication of notice of the same by press release. The Company initially designated the following notes as “Designated Notes,” each as defined in above: the 2024 First Lien Notes, the 2024 Second Lien Notes, and the 2025 Notes. On February 3, 2023, the Company published a press release announcing the de-designation of the 2024 First Lien Notes and the 2024 Second Lien Notes.

Pursuant to the terms of the Warrant Agreement, a holder may elect to pay an additional amount equal to $1.8525 (being 0.15 multiplied by the Exercise Price) in exchange for an additional number of shares of common stock equal to the product of 0.15 and the Warrant Shares Per Warrant applicable to the relevant exercise on the terms specified in the Warrant Agreement. If all Warrants were exercised as of March 31, 2023 and each holder were to elect to pay the additional $1.8525 to receive additional

shares, the Company would be required to issue an additional approximately 2.9 million shares in settlement of the incremental exercise price received.

The Warrants expire on December 19, 2023, subject to (i) the right of the Company to redeem the Warrants on not less than 20 calendar days’ notice (any such date of redemption, the “Redemption Date” and any such date of notice a “Redemption Notice”) at a price of 1/10 of $0.01 per Warrant and (ii) the automatic acceleration of the Expiration Date following the Price Condition Date, as defined and described below.

Unless the Company has previously issued a Redemption Notice with respect to the Warrants, then following the last day of the first 30 consecutive trading day period to occur in which daily volume weighted average prices of the shares of Common Stock has been at least equal to the then applicable Implied Per Share Exercise Price on each of 20 trading days (whether or not consecutive) (the “Price Condition”), the Expiration Date will automatically accelerate to the date that is the 5th business day following the Price Condition Date; provided that the Company may, at its sole option, elect a later Expiration Date by providing public notice no later than the Price Condition Date. The “Price Condition Date” is the first business day following the last Trading Day of the period in which the Price Condition is met.

Any holder that exercises any Warrants from and after (a) 5:00 p.m. New York city time on the earlier of (x) a Price Condition Date and (y) the date that the Company issues a Redemption Notice until (b) 5:00 p.m. New York City time on, as applicable, (x) the Expiration Date and (y) the business day immediately preceding the Redemption Date (the last day of such period, the “Over-Subscription Deadline”), may, subject to the terms of the Warrant Agreement, elect to subscribe for any or all of the shares of Common Stock issuable pursuant to any outstanding but unexercised Warrants as of the Over-Subscription Deadline (the “Over-Subscription Privilege”). To exercise the Over-Subscription Privilege, a holder must deliver an amount in cash equal to the elected over-subscription shares multiplied by the then applicable Implied Per Share Exercise Price (such amount, the “Elected Over-Subscription Shares Amount”) at the same time as the basic warrant exercise right is exercised. Any excess payments received will be returned, without interest, promptly following the settlement date.

An ownership limitation is in place such that a holder of Warrants is not permitted to exercise Warrants for any shares of common stock if following such exercise the holder will have beneficial ownership of common stock in excess of 4.9% of the then issued and outstanding common stock (excluding shares held by subsidiaries); provided, that a holder of Common Stock in excess of 4.9% of the issued and outstanding common stock as of 5:00 p.m. New York City time on December 1, 2022 will be entitled to exercise Warrants received in the Warrant Distribution, but only to the extent such holder’s receipt of such common stock is permitted by a waiver in effect at such time that constitutes “Prior Approval of the Company” under the Tax Benefit Preservation Plan, dated March 11, 2022, between the Company and Computershare Trust Company, N.A., as rights agent.

The Exercise Price and the number of shares of common stock issuable upon exercise are subject to certain anti-dilution adjustments, including for share dividends, splits, subdivisions, spin-offs, consolidations, reclassifications, combinations, noncash distributions, and cash dividends.

The common stock warrants are accounted for as derivative liabilities in accordance with ASC 815-40 and included within accrued liabilities on the accompanying condensed consolidated balance sheets. The Company measured the Warrants at fair value as of the issuance date using a Monte Carlo pricing model, a Level 3 fair value measurement (as described below), due to the level of market activity. Inherent in the option pricing simulation are assumptions related to expected stock-price volatility, expected life and risk-free interest rate. The Company estimates the volatility of the Warrants based on implied and historical volatility of the Company’s common stock. The risk-free interest rate is based on the U.S. Treasury zero-coupon yield curve on the grant date for a maturity similar to the expected remaining life of the Warrants. The expected life of the Warrants is based on the Company’s ability to redeem the Warrants, subject to a 20 calendar-day notice period, as well as the automatic acceleration of the Expiration Date following the Price Condition Date. During the three months ended December 31, 2022, due to increased trading volume, the Company began remeasuring outstanding Warrants using the Warrants trading price, a Level 1 fair value measurement (as described below). The Warrants are remeasured at each balance sheet date. Warrants remeasurement adjustments are recognized in warrants remeasurement gain, net on the accompanying condensed consolidated statements of operations.

At distribution, the fair value of the Warrants was $19,500. At March 31, 2023, the fair value of the Warrants was approximately $9,563 and $9,796 of warrants remeasurement gain has been recognized in the year ended March 31, 2023. Following the issuance on December 19, 2022 through March 31, 2023, approximately 0.4 million Warrants have been exercised

Leases

Leases

The Company leases office space, manufacturing facilities, land, vehicles, and equipment. The Company determines if an agreement is or contains a lease at the lease inception date and recognizes right-of-use assets (“ROU”) and lease liabilities at the

lease commencement date. A ROU asset and corresponding lease liability are not recorded for leases with an initial term of 12 months or less (“short-term leases”).

ROU assets represent the Company's right to use an underlying asset during the lease term, and lease liabilities represent the Company's obligation to make lease payments arising from the lease. The determination of the length of lease terms is affected by options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. The existence of significant economic incentive is the primary consideration when assessing whether the Company is reasonably certain of exercising an option in a lease. Both finance and operating lease ROU assets and liabilities are recognized at commencement date and measured as the present value of lease payments to be made over the lease term. As the interest rate implicit in the lease is not readily available for most of the Company's leases, the Company uses its estimated incremental borrowing rate in determining the present value of lease payments. The estimated incremental borrowing rate is derived from information available at the lease commencement date. The lease ROU asset recognized at commencement is adjusted for any lease payments related to initial direct costs, prepayments, and lease incentives.

For operating leases, lease expense is recognized on a straight-line basis over the lease term. For finance leases, lease expense comprises the amortization of the ROU assets recognized on a straight-line basis generally over the shorter of the lease term or the estimated useful life of the underlying asset and interest on the lease liability. Variable lease payments not dependent on a rate or index are recognized when the event, activity, or circumstance in the lease agreement upon which those payments are contingent is probable of occurring and are presented in the same line of the consolidated balance sheet as the rent expense arising from fixed payments. The Company has lease agreements with lease and non-lease components. Non-lease components are combined with the related lease components and accounted for as lease components for all classes of underlying assets.

Retirement Benefits

Retirement Benefits

Defined benefit pension plans are recognized in the consolidated financial statements on an actuarial basis. A significant element in determining the Company's pension (income) expense is the expected long-term rate of return on plan assets. This expected return is an assumption as to the average rate of earnings expected on the funds invested or to be invested to provide for the benefits included in the projected pension benefit obligation. The Company applies this assumed long-term rate of return to a calculated value of plan assets, which recognizes changes in the fair value of plan assets in a systematic manner over five years. This produces the expected return on plan assets that is included in pension (income) expense. The difference between this expected return and the actual return on plan assets is deferred. The net deferral of past asset (losses) gains affects the calculated value of plan assets and, ultimately, future pension (income) expense.

The Company periodically experiences events or makes changes to its benefit plans that result in curtailment or special charges. Curtailments are recognized when events occur that significantly reduce the expected years of future service of present employees or eliminates the benefits for a significant number of employees for some or all of their future service.

Curtailment losses are recognized when it is probable the curtailment will occur and the effects are reasonably estimable. Curtailment gains are recognized when the related employees are terminated or a plan amendment is adopted, whichever is applicable.

From time to time, the Company may enter into transactions that relieve it of primary responsibility for all or more than a minor portion of certain of its pension benefit obligations. When these transactions are effected through an irrevocable action that relieves the Company of primary responsibility for its pension or other postretirement benefit obligations and eliminates significant risks related to the obligation and the related assets used to effect the transaction, they are considered settlements, as defined by ASC 715, Compensation – Retirement Benefits. When a transaction meets the definition of a settlement, at the time of settlement the Company recognizes as a gain or loss the pro rata amount of the net gain or loss in accumulated other comprehensive loss based on the proportion of the projected benefit obligation settled to the total projected benefit obligation.

As required under ASC 715, the Company remeasures plan assets and obligations during an interim period whenever a significant event occurs that results in a material change in the net periodic pension cost. The determination of significance is based on judgment and consideration of events and circumstances impacting the pension costs.

At March 31 of each year, the Company determines the fair value of its pension plan assets as well as the discount rate to be used to calculate the present value of plan liabilities. The discount rate is an estimate of the interest rate at which the pension benefits could be effectively settled. In estimating the discount rate, the Company looks to rates of return on high-quality, fixed-income investments currently available and expected to be available during the period to maturity of the pension benefits. The Company uses a portfolio of fixed-income securities, which receive at least the second-highest rating given by a recognized ratings agency.

Contingencies

Contingencies

Contingences are existing conditions, situations or circumstances involving uncertainty as to possible gain or loss that will ultimately be resolved when future events occur or fail to occur. Such contingencies include, but are not limited to environmental obligations, litigation, regulatory investigations and proceedings, product quality, and gains or losses resulting from other events and developments. Liabilities for loss contingencies are accrued in the amount of its best estimate for the ultimate loss when a loss is considered probable of having been incurred and is reasonably estimable. When there appears to be a range of possible costs with equal likelihood, liabilities are based on the low-end of such range. Disclosure is provided for material loss contingencies when a loss is probable but a reasonable estimate cannot be made, and when it is reasonably possible that a loss will be incurred or the amount of a loss will exceed the recorded provision. The Company regularly reviews contingencies to determine whether the likelihood of loss has changed and to assess whether a reasonable estimate of the loss or range of loss can be made. Contingencies that might result in gains are generally not accrued until the contingencies are resolved and the gain is realized or realizable. Refer to Note 17 for further disclosure.

Fair Value Measurements

Fair Value Measurements

Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. When determining fair value measurements for assets and liabilities required to be recorded at fair value, the Company considers the principal or most advantageous market in which it would transact and also considers assumptions that market participants would use when pricing an asset or liability. The fair value hierarchy has three levels of inputs that may be used to measure fair value: Level 1—Unadjusted quoted prices in active markets for identical assets or liabilities; Level 2—Unadjusted quoted prices in active markets for similar assets or liabilities, or unadjusted quoted prices for identical or similar assets or liabilities in markets that are not active, or inputs other than quoted prices that are observable for the asset or liability; and Level 3—Unobservable inputs for the asset or liability. The Company has applied fair value measurements when measuring the warrants (refer to the above disclosure), when comparing the carrying value of assets held for sale with the related fair value less cost to sell (see Note 3), when measuring long-lived asset impairment in fiscal 2021 (see above within the disclosure of the Company’s goodwill and intangible asset accounting policies), when disclosing the fair value of its long-term debt not recorded at fair value (see Note 10) and when measuring its pension and postretirement plan assets (see Note 15).

Income Taxes

Income Taxes

The Company accounts for income taxes using the asset and liability method. The asset and liability method requires recognition of deferred tax assets and liabilities for expected future tax consequences of temporary differences that currently exist between tax bases and financial reporting bases of the Company's assets and liabilities. A valuation allowance is provided on deferred taxes if it is determined that it is more likely than not that the asset will not be realized.

Management judgment is required to determine the amount of benefit to be recognized in relation to an uncertain tax position. The Company uses a two-step process to evaluate tax positions. The first step requires an entity to determine whether it is more likely than not (greater than 50% chance) that the tax position will be sustained. The second step requires an entity to recognize in the financial statements the benefit of a tax position that meets the more-likely-than-not recognition criterion. The amounts ultimately paid upon resolution of issues raised by taxing authorities may differ materially from the amounts accrued and may materially impact the financial statements of the Company in future periods. The Company recognizes penalties and interest accrued related to income tax liabilities in the provision for income taxes on its consolidated statements of operations.

Supplemental Cash Flow Information

Supplemental Cash Flow Information

In November 2021, the Company entered into an agreement with the DOT under the AMJP for a grant of up to $21,259. The receipt of the full award was primarily conditioned upon the Company committing to not furlough or lay off a defined group of employees during the six-month period of performance between November 2021 and May 2022. The Company received approximately $19,400 under the agreement, of which approximately $10,630 was received in the year ended March 31, 2022, and the remainder of which was received in the year ended March 31, 2023. In July 2022, the Company received a letter from the DOT confirming that the Company had satisfied the reporting requirements under the AMJP. In the twelve months ended March 31, 2023 and 2022, the Company recognized as a reduction in cost of sales approximately $5,300 and $14,064, respectively, the former representing the final balance of the earned grant benefit.

For the fiscal years ended March 31, 2023, 2022, and 2021, the Company paid $4,565, $5,382, and $2,297, respectively, for income taxes, net of income tax refunds received.
