Overview

DRS is a leading provider of defense products and technologies that are used across land, air, sea, space and cyber domains. Our diverse array of defense systems and solutions is offered to all branches of the U.S. military, major aerospace and defense prime contractors, government intelligence agencies and international military customers for deployment on a wide range of military platforms. We focus our capabilities in areas of critical importance to the U.S. military, such as sensing, electronic warfare (“EW”), cyber security, network computing, communications, force protection and electrical power conversion and propulsion. As a mid-tier defense company with a portfolio that includes internally developed proprietary intellectual property (“IP”) and offerings at the component, sub-system and system level, we are able to serve as either prime contractor or a sub-contractor on key contracts, affording us flexibility in how we approach the market.

Our alignment with the nation’s top defense priorities has allowed us to achieve a 16% compounded annual growth rate (“CAGR”) in revenues from the year ended December 31, 2016 through the year ended December 31, 2019. This growth, which exceeded the DoD budget CAGR of 5.8% during such period and drove our annual revenue to approximately $2.7 billion for the year ended December 31, 2019, was driven by organic growth. During the same period, our net earnings (loss) improved by $237 million to $75 million, our operating earnings grew $160 million to $163 million and our Adjusted EBITDA grew $81 million to $234 million (CAGR of 15%). Adjusted EBITDA is a non-GAAP measure. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Key Financial and Operating Measures—Non-GAAP Financial Measures” for a reconciliation of Adjusted EBITDA to net earnings.

We have a 50-year legacy of designing and manufacturing innovative and differentiated products and solutions for military applications. From our earliest sonar systems that were instrumental in detecting enemy submarines, to today’s best-in-class electro-optical sensors, we have continually developed advanced technologies to address complex military challenges. Throughout much of our history, we have targeted our investments towards the highest growth areas of the DoD defense budgets. Today, we employ approximately 6,700 people including a substantial number of highly trained engineers and personnel with security clearances to support classified programs for the U.S military.

We focus on products, systems and solutions that can be adapted for installation on a wide range of military platforms. This allows us to leverage our technology investments to expand revenue opportunities. Our high-technology solutions are designed to transition from one military platform to another. In addition, we have a significant installed base of products and solutions, which allows us to enhance revenue opportunities by providing upgrades to existing platforms. This gives us a resilient position to offer new solutions and technology in changing budget environments. Our growth has been facilitated by our longstanding relationships and position as a trusted partner with the U.S. military, intelligence community and industry customers. Together, these characteristics allow us to pivot quickly to

1

address emerging needs for our customers and generate growth opportunities in today’s dynamic defense market.

We operate in three segments: Advanced Sensor Technologies, Network Computing & Communications and Integrated Mission Systems. We have achieved significant growth over the past five years by aligning our investments and technology development to address the greatest threats to U.S. defense interests.

Advanced Sensor Technologies: Our Advanced Sensor Technologies segment provides world-class electro-optical sensor technologies, laser systems, EW systems and intelligence and surveillance solutions to U.S. military and intelligence community customers.

Our technologies and products are used on legacy and new military platforms, end-to-end network communication systems, satellite services and cyber solutions. We are a leading provider of ruggedized computing equipment, having provided advanced tactical computing units for ground combat vehicles and command post operations for more than two decades. During this period we have delivered more than 125,000 units. For the U.S. Navy and its allies, we provide naval computing infrastructure, network and data distribution, radar and rugged naval control systems, which are present on naval surface and subsurface combatant vessels. Across the full spectrum of our network computing capabilities, we have leadership positions at both the product and sub-systems levels. Our global communications network is a worldwide network of terrestrial and satellite bandwidth that ensures our customers’ data is secure and reliable. As a result of this capability, we are positioned as one of the leading providers of secured satellite communications to the U.S. military.

Integrated Mission Systems: Our Integrated Mission Systems segment provides critical force protection, vehicle integration, transportation and logistics and electrical conversion and ship propulsion systems to the U.S. military. Our force protection systems protect service members and military assets from evolving threats and include solutions for counter-unmanned aerial systems, short-range air defense systems and active protection systems on ground vehicles. In 2018, we were awarded the Expedited Active Protection System program by bringing the TROPHY™ Active Protection System (“APS”) to the U.S. market, making us the leading U.S. provider of active protection systems for the U.S. Army. We were also awarded the Initial Maneuver Short-Range Air Defense (“IM-SHORAD”) Mission Equipment Package Program for the U.S. Army that year, culminating an 18-month cycle from development to customer delivery. We have military transportation and logistics offerings and ground vehicle integration capabilities to support U.S. forces in a wide range of operational environments. We provide power conversion and propulsion systems for the U.S. Navy’s top priority shipbuilding programs, building on our legacy of providing power components and systems for nearly all naval combat vessels for three decades, positioning us to continue as a leading provider of electrical ship propulsion systems and components for the U.S. Navy.

U.S. Defense Market Trends and Market Opportunities

Our core markets have experienced strong growth. The DoD defense budget has grown at a CAGR of 5.8% from 2016 to 2019, reflecting the shift of the DoD’s priorities from a focus on global terrorism to emerging threats from more sophisticated and technologically advanced adversaries requiring enhanced

2

capabilities across the DoD. Additionally, we foresee growth opportunities in foreign military sales and direct commercial sales, particularly as international allies require similar force modernization.

The DoD is our largest customer and, for the year ended December 31, 2019, accounted for approximately 89% of our business as an end-user, with revenues principally derived directly or indirectly from contracts with the U.S. Army and U.S. Navy, which represented 40% and 36%, respectively, of our total revenues for the year ended December 31, 2019. The stated U.S. National Defense Strategy is to “compete, win and deter” in a challenging and complex international security environment. The current landscape is defined by rapid technological change and competition from emerging peer and near-peer adversaries who are nation states that are becoming great powers. Every domain of U.S. military advantage is expected to be contested, including air, land, sea, space and cyberspace. U.S. forces facing these new threats are in need of modernization as readiness has been strained following nearly two decades of continuous conflict with both traditional and novel adversaries. In order to face these challenges, the U.S. military will likely need to balance limited resources between new high-cost technological capabilities and upgrades of existing equipment.

In today’s threat environment, the U.S. military is positioning itself for non-stop, continuous competition against these rising nation state threats. Military services are increasingly moving towards multi-domain operations that now include both space and cyberspace domains in addition to the air, land and sea domains. The creation of the U.S. Space Force is also expected to drive new requirements for high technology defense capabilities, including increased space sensing and evolution of communications approaches. Even as new spending priorities shift towards addressing high-end threats, the U.S. military knows that it cannot compete with yesterday’s weapons or equipment. Military modernization programs and priorities are expected to provide both opportunities for new solutions and for upgrades to existing platforms. We believe that companies with an existing installed base of hardware will be able to perform upgrades to provide modernization solutions at a lower cost. Companies with strong customer relationships and outstanding execution will more effectively maintain program positions.

In this new military environment, U.S. forces are seeking the ability to sense further from a greater distance and enhance their reach across the spectrum of warfare. Increased use of sensor technologies enables forces to detect threats further and more quickly and deliver rapid, forceful responses. Sensors and laser systems are expected to enable optionally manned and autonomous platforms for the future.

The need for greater situational understanding for the warfighter also drives the need for increased data and communications bandwidth to and from command centers to forward-positioned military platforms and dismounted soldiers. Network computing and communications systems need to provide deployed forces with access to secure data to promote information-sharing and situational understanding for faster decision-making. Battlefield management systems and individual soldier communications systems require secure rugged computing solutions and are becoming increasingly interoperable with current combat air forces and naval computing infrastructure. Encrypted data and cyber protection capabilities aim to ensure that the data U.S. forces receive is trusted and protected from enemies. This capability is intended to allow forces to be more mobile and geographically dispersed while operating with immediate access to trusted information. Satellite communications systems also provide data to U.S. warfighters around the globe and are projected to increasingly utilize satellite constellations at all altitudes for redundancy, lower latency, expanded bandwidth and security.

U.S. forces are in need of greater force protection technologies. Emerging requirements for counter-unmanned aerial systems, active protection, infrared countermeasures and air defense systems require rapid deployment to keep U.S. military platforms and personnel safe from growing threats. The U.S. military is also focusing efforts on transportation and logistics capabilities, ensuring that their trained and equipped personnel and supplies can make it to the battlefield wherever that may be. All of the increased sensing, self-protection, directed energy, communications and computing needs for the warfighter require significantly higher levels of mobile power than in the past. Electrical power generation, conversion, storage and distribution and on-board vehicle power solutions will provide U.S. forces the energy they need in the future to win in this era of competition.

3

The U.S. military budget accounts for nearly 40% of the world’s defense spending and foreign military allies often select U.S. military solutions to train, equip and modernize their forces to enhance interoperability. Beyond the opportunity for direct commercial and foreign military sales to these foreign countries, many allies leverage U.S. funding and equipment, providing opportunities for U.S. defense contractors offering solutions that can be sold internationally.

The global community is in a period of rapid technological change and new commercial technologies may change society and, ultimately, the character of conflicts. We believe that investing in high technological capabilities, developing proprietary intellectual capability, as well as integrating leading-edge commercial technology into our solutions will provide us with a competitive advantage. New acquisition programs are expected to seek innovative solutions. The need for innovation is more critical than ever, and to accelerate innovation, the DoD has deployed more rapid acquisition methods. We believe that these methods will provide greater opportunities for companies with proven abilities to quickly develop and deploy new technologies. The DoD has placed a high priority on defense procurement reform to speed up the development of new key capabilities, increase responsibility and accountability for major acquisition programs and reduce acquisition risk. As a result, we believe that mid-tier companies, such as DRS, with proven technological capabilities and an agile decision-making structure are positioned to rapidly respond to emerging requirements.

Our Products and Solutions

The DoD is placing its focus and investment priorities in several platforms and capabilities where we have compelling offerings and market share. These offerings include: Ground Vehicle Sensors; Soldier Sensor Systems; EW & Cyber; Network Computing; Communications; Force Protection; Transportation and Logistics; and Electrical Power & Propulsion. These directly align with our three segments: Advanced Sensor Technologies, Network Computing & Communications, and Integrated Mission Systems. In these areas, we have distinguishing capabilities, core technologies and IP underlying our product portfolio that we believe provide us with a sustainable differentiation from our competitors. We believe that our installed base of existing products and platform-agnostic offerings provide an opportunity for our business to continue to grow.

Advanced Sensor Technologies

Our Advanced Sensor Technologies segment provides world-class cryogenically cooled and uncooled infrared sensor technologies, laser systems, EW systems and intelligence and surveillance solutions to the U.S. military and intelligence community customers. Our products and solutions have significant capabilities and core technologies to meet the warfighter’s need for increased battlefield awareness and longer range sensing. Our infrared focal plane array foundry produces cooled and uncooled infrared sensors and our IP provides us with key technology differentiators and builds upon our long legacy of market-leading technology.

Ground Vehicle Sensors – The U.S. military has identified specific needs for advanced sensor technology for ground vehicles, including electro-optical and advanced detection capabilities to enhance battlefield understanding, vehicle protection and vehicle targeting capabilities. Our market-leading sensor products include third-generation infrared sensing, fused sensing and sensors for threat detection and situational awareness, which we believe position us well for these opportunities. We are a leading provider of uncooled focal plane arrays and brownout solutions (which are sensors that can see through blowing sand). We are also a leader in ground vehicle sensor sighting systems led by our third-generation infrared imaging systems.

Soldier Sensors – Our complement of soldier sensor systems employs state-of-the-art sensors, precision targeting capabilities and optics designed to improve infantry combat effectiveness. We offer a family of innovative electro-optical and infrared systems for soldiers, from our legacy imaging system, the Thermal Weapons Sight, to the next generation of thermal weapon sights being produced today. We believe that our current position on next-generation soldier precision targeting programs will enable us to

4

compete effectively in this area of growing need. Our uncooled sensor technology also positions us well to support the future of soldier goggle systems.

EW & Cyber – We have significant technological capabilities and program experience in EW & Cyber and offer integrated capabilities for multi-domain operations to supplement kinetic warfare. We have developed mounted and dismounted EW systems, EW software and training systems and intelligence solutions across a broad range of platforms. We believe that our capabilities in integrated mounted and dismounted ground EW, exploitation and cyber-based multi-domain operations position us well in this area of growing DoD priority. We have leveraged international EW programs to develop our capabilities for DoD offerings and have invested to meet developing U.S. Army and U.S. Marine Corps requirements for integrated solutions to address threats which are emanating from peer and near-peer adversaries.

Force Protection – Aircraft Survivability – Our Advanced Sensors Technology segment also features quantum cascade laser (“QCL”) technology which, along with our advanced two-color infrared sensors, have enabled us to support a high-profile U.S. Navy contract for advanced systems to protect aircraft from ground-launch missiles. We are also a critical partner on the U.S. Army’s common infrared countermeasures program.

Other Advanced Sensor Technologies Capabilities –Our aircraft training instrumentation systems were selected for the high-profile Joint Strike Fighter program that has been the leading U.S. and allied forces military air platform in development over the past two decades. We are also a leading provider of the aircraft training instrumentation which deploy on both legacy and modern aircraft and are required for aircraft training programs.

Our Network Computing & Communications segment provides an array of network computing products and sub-systems that bring trusted and resilient communications and computational resources to U.S. and international military forces, allowing them to rapidly share data and improve situational understanding. We provide trusted computing systems for ground vehicles, naval computing infrastructure, network and data distribution programs, rugged naval computational and control systems and networked communications. We also provide terrestrial and satellite communications for the U.S. Army, U.S. Navy, U.S. Special Forces, and intelligence communities.

Network Computing - The U.S. military has recently shifted its computing paradigm for command, control, communications, computers, intelligence, surveillance and reconnaissance to include cyber capabilities. Our Mounted Family of Computing Systems (“MFoCs”) and MFoCs-II have earned us a reputation as a leading provider of mounted battle management systems hardware in the U.S. We have invested in cyber defense and trusted computing capabilities over the past several years to protect information at the edge of the battlefield. We have also transformed our legacy of naval display and computing equipment over the past several years, to secure a position as a leading provider of surface combat system components, submarine combat systems and command and control system components. We are a leading provider of naval ship communications, integrated logistics support and sustainment and manufacturing services to U.S. and allied military customers. We hold a leading market share in Command, Control, Communications, Computers and Intelligence (“C4I”) programs for the U.S. Navy, including those that will be upgraded as the fleet continues to modernize. For submarines, we provide hardware which is planned to be upgraded continuously over a two-year cycle. In addition, our joint venture, Advanced Acoustic Concepts, LLC (“AAC”), focuses on underwater products, acoustic training systems, and related products and services.

Communications – We are contracted on two of the U.S. military’s top five satellite communications programs, including its largest, serving special operations forces with terrestrial and space bandwidth. This long-standing program provides secure and reliable communications for the U.S.’s forward-deployed military forces across the globe, and is well positioned to meet future needs. Our contracts on these programs make us one of the largest satellite communications providers for the U.S. military. We believe

5

that our legacy and outstanding reputation with the U.S. military will enable us to continue to be a leading communications provider for all DoD services.

Integrated Mission Systems

Our Integrated Mission Systems segment supports the U.S. military’s need to deter and defend against increasingly lethal adversaries through a wide range of force protection solutions, integrated mission equipment, transportation and logistics products, naval power technologies and forward-deployed electrical power solutions. This segment enables us to maximize our customer offerings by integrating our products and systems onto platforms. We believe that our leading position in naval electrical power and propulsion will position us to help meet the U.S. military’s future electrical power needs as it increasingly deploys high technology capabilities to its forces.

Force Protection – DRS is an integrator of systems in ground vehicles, including reconnaissance and surveillance, mission support and vehicle survivability and protection. Protecting U.S. service members and valuable defense assets is always a top DoD priority. To help accomplish this mission, we have a family of key force protection systems, including counter-unmanned aerial systems and portable ground radar, active protection systems, modular combat vehicle turrets and stabilized sensor suites. We believe that our record providing the TROPHY™ APS to the U.S. Army enhances our reputation and positions us well to provide future vehicle protection systems. Our short-range air defense mission equipment package and mounted counter-unmanned aerial systems integrate market-leading technologies that are ready to rapidly deploy to the field in upcoming competitive pursuits.

Transportation and Logistics – DRS is a provider of transportation and logistics solutions for the DoD, including bridging systems, cargo loaders and trailers. Our Tunner and Halvorsen programs have provided the U.S. Air Force with rapidly deployable, high-reach mechanized aircraft loaders that can lift up to 60,000 and 25,000 pounds, respectively, of cargo onto military aircraft. The Joint Assault Bridge program positions us well as the U.S. Army is looking to expand its tactical bridging capabilities. We believe that our legacy position in heavy military trailers will allow us to win new opportunities as the U.S. Army looks for increased solutions. We also have capabilities in military fuel and water handling and distribution which can support U.S. military forces in a variety of challenging forward deployed environments.

Electrical Power & Propulsion – DRS is a leading provider of next generation electrical propulsion components and systems for the U.S. Navy, with significant capabilities to service the fleet’s future needs, including on the Columbia-class submarine program which is integral to the United States’ deterrence strategy and among its highest priority programs. Beyond electrification of its fleet, the U.S. Navy will require increased power to expand and modernize its vessels, including for the introduction of laser weapons. This increased power demand will require improved power generation, storage, conversion, management and distribution, which align with the core competencies of this segment.

Our Competitive Strengths

As a diverse, defense technology company that is primarily focused on U.S. military programs, we have significant attributes that make us well positioned in the market. With a heritage of excellence in defense products, systems and solutions, we have transformed ourselves into a leading defense technology company with capabilities in sensing, electro-optics and laser systems, a critical provider of trusted network computing and communications systems and a key leader in integrated mission systems. We believe that we are positioned to grow our market position as a leading mid-tier U.S. defense technologies provider.

Our innovative portfolio is well positioned for core platform wins.

Over the past five decades, DRS has advanced its portfolio through focused innovation, targeted investments, selective partnerships and mergers and acquisitions. DRS has solutions for a number of military platforms and serves the branches of the U.S. military, and competes at the prime contractor,

6

systems, supplier, or component level. Our core set of defense technologies and capabilities have applications that cross our three segments, allowing us to leverage research and development (“R&D”) and IP across multiple product lines, platforms and end markets. We also provide higher-value integrated sub-systems and systems and have a goal of increasing scope and market share by integrating our own products and technologies.

Our portfolio of defense technologies is strategically aligned with key DoD priorities.

We believe that our product and technology portfolio aligns with rising great power competition needs and modernization efforts, which are high priorities for DoD spending. Our technology portfolio and knowledge of the U.S. military enable us to win positions on key programs and adapt quickly to changing customer dynamics. Our size and lean management structure allow us to shift our focus to changing priorities rapidly to best serve our customers’ growing needs. Our recent execution performance in short-range air defense exemplifies this ability, as we were able to rapidly develop and field new technology to address urgent needs of the warfighter in an extremely short procurement cycle.

We hold an embedded position on key defense platforms and with prime contractors, supported by our installed base of existing products spanning U.S. Army, U.S. Navy and U.S. Air Force platforms.

Our current installed base of existing products spans over 300,000 computer and display systems that are fielded globally, approximately 60,000 enhanced driver vision systems for military combat vehicles, over 50,000 thermal weapon systems and critical naval computing infrastructure and technology on every U.S. naval combatant vessel in service. The notable platforms for this installed base include: surface ships, submarines, tracked and wheeled ground vehicles, fixed and rotary wing aircraft, unmanned aircraft, operating bases, and commercial vehicles and facilities. This installed base of existing products provide us opportunities for upgrades and new business that leverages these solutions.

Our record of growth should drive profitability due to program lifecycle evolution, sole source positions and operational efficiencies.

Over the past four years, we have had a revenue CAGR of 16%, operating earnings expanded by $160 million and our Adjusted EBITDA Margin has increased to 8.6%. We have accomplished this through key program wins and sole-source positions, including prominent positions on the Columbia-class submarine program, MFOCS ruggedized computing battle management program, next generation of thermal weapon sights and our active protection system awards. Going forward, we anticipate that recent investments will drive profitability expansion and corresponding cash flow generation. As our program lifecycle in several key programs shifts from lower-margin, fixed-price development efforts to production, and topline growth brings more operational efficiencies, we expect to improve margin. Across our business, our continuous improvement culture is embodied in our Operational Excellence initiative called “Always Performing For Excellence,” or “APEX,” which strives to reduce cost and improves efficiencies while increasing the quality of our products and services.

Our highly experienced management team and talented workforce have transformed DRS.

Our management team has transformed DRS into the market-leading, high-growth, technology company it is today by focusing attention and investment on the fastest growing areas of the DoD budget. We have done this through an active portfolio management process that targeted investment to growing technological capabilities and acquisitions of smaller accretive companies that fill key strategic gaps in our portfolio, and by creating partnerships or joint ventures to supplement our own IP. The result of these efforts has led DRS to be well positioned in the U.S. defense market. Our management team has an average tenure of 15 years with the Company and nearly 30 years in the industry.

Our work force of approximately 6,700 people is highly innovative and we maintain a culture that fosters and rewards growth, problem-solving, technology development and process improvements. We have approximately 1,350 world-class engineers highly trained to work on programs in sensing, electro-

7

optical infrared systems, laser systems, network computing, communications systems, integration and power propulsion. We maintain over 2,000 security clearances to allow engineers and management to carry on business activities for our customers’ classified programs. Our strong commitment to diversity, inclusion, succession planning and training has fostered a highly collaborative and motivated work force. Our human resources policies and benefits have been designed to allow us to recruit and retain top talent.

We are focused on sustainability and diversity.

We strongly believe that in order to succeed as a company, we must remain a strong and positive contributor to the communities where we do business, and the greater world around us. Sustainability to us means taking important steps towards protecting the environment, engaging in corporate social responsibility, ensuring a safe work force and promoting diversity. We have enacted a sustainability risk management model to take action towards responsible consumption. We have focused our corporate giving program on military veterans and have initiated a program called MyCommunity that matches donations to local charities and provides paid volunteer hours to employees. We created a Diversity Advisory Group to improve our diversity and inclusiveness so that we look like the communities in which we operate. We have targeted increases in minority hiring and women in management and overall women in the workforce, which is 3.1% higher than our industry average.

Our Growth Strategy

Our growth strategy is focused on four pillars: targeting investment to drive organic growth; executing on our programs to enhance profitability; actively managing our portfolio for optimization; and taking care of our people. Our goal is to grow and increase margins faster than the overall defense market through focused market selection, technology differentiation and operational excellence. Our vision is to be the best mid-tier defense technology company in the U.S. market.

Targeting Investment to Drive Organic Growth

We strategically select the markets where we compete and the programs on which we bid.

•We target programs in markets where we have strong core technology and where the DoD is focused. We seek to compete only in the areas in which we have a technological or market advantage, and which will attract funding. As an example, our core technology in high-performance receivers/transceivers is sought after by our customers for their wide-bandwidth and high signal dynamic range. These features are required for modern EW systems being developed for the U.S. Army, U.S. Marine Corp. and other customers to capture, exploit and/or disrupt modern signals.

•We target our investments in core technologies in areas of high market growth. Our investments fill gaps, create leading market offerings and make capital improvements to our business. We are also awarded, and leverage, significant customer research and development funding to complement our investments.

Executing on Our Programs to Enhance Profitability

We remain focused on continuing to drive operational enhancements and efficiencies, which we believe will result in improved profitability over time. We believe that our world-class technology and innovative solutions coupled with the transition of development programs into production will serve as the foundation for continued profitable growth.

•We believe that outstanding performance and timely execution on our programs will win us new business and lead to profitable growth, including new opportunities for follow-on orders which will add to our growing production base. Our recent short-range air defense program is an example of

8

a program that we were able to win because of our reputation with the customer and our ability to quickly react to their needs.

•Integrated systems offerings of our products and systems should further expand margins as we continue to grow the topline. Our Integrated Missions Systems business, for example, has strong integration capabilities which will enable us to grow content on programs as we increase our role from smaller sub-systems into full systems integration.

•Successful execution on key development programs in early phases is expected to drive a transition to higher margin business in production, bringing sustained profitable success. Our Columbia-class submarine program is an example of a fixed-price development program that we invested in while recognizing that it will deliver long-term profitable growth, beginning in 2021, when it transitions into production.

•Our APEX program focuses on the achievement of operational savings in production, supply chain and our overall cost structure. The APEX program’s goal is to strive for continuous improvement through unification of our business practices, tools and metrics, ongoing employee training and innovation. Commitment to excellence requires us to challenge ourselves to exceed our customers’ expectations. A culture of continuous improvement will allow us to improve our efficiency and increase our margins.

Actively Managing our Portfolio for Optimization

We manage our portfolio to optimize our growth in areas where we have the strongest core technology base, where we have a competitive cost structure and where the defense market is growing.

•DRS has a portfolio of products and services that we believe are positioned to move up the value chain to provide sub-systems and integrated systems and solutions. We regularly assess our portfolio to ensure strong alignment with our customers’ needs and priorities and consider accretive acquisitions in areas where we have strategic gaps to address our customer’s needs.

•We employ a strategy of active IP management to acquire technologies and IP through partnerships, teaming arrangements, strategic licenses and other business arrangements. This active IP management strategy allows us access to new technologies in a disciplined manner to maintain the strength of our diversified portfolio.

Continue to Take Care of Our People

We seek to recruit and retain the highest caliber of talent through competitive pay and benefits packages, diverse and inclusive personnel policies and fostering an innovative and modern workforce.

•We strive to maintain the highest ethical standards and foster a collaborative workplace to ensure a strong culture in our people.

•We constantly assess and make thoughtful changes to our personnel practices, including changes to our pay and benefits packages and increased training and growth opportunities, to ensure that we attract and retain top talent.

•We have implemented a strong diversity and inclusion program to ensure that our workforce looks like the communities in which they operate. This helps us to bring diverse ideas and perspectives to decision-making and problem-solving and allows us to draw from the largest pool of available talent.

History of the Company

DRS was founded in 1969, in Mount Vernon, New York, as Diagnostic Retrieval Systems, and soon became best known by its acronym, DRS. In 1981, we first became a publicly traded company. Over the

9

subsequent decades, DRS experienced a period of rapid growth driven in large part by numerous acquisitions. In 2008, our stock ceased to be publicly traded when we were acquired by the Italian-headquartered Finmeccanica S.p.A. (now known as Leonardo S.p.A.) and we subsequently rebranded ourselves as Leonardo DRS. Since the Leonardo acquisition, we have operated under agreements with the DoD and related security policies in order to limit our foreign parent’s ability to control our business operations.

Governance Structure

Following completion of this offering, we expect that Leonardo S.p.A. will indirectly hold approximately          % of our common stock through US Holding (or        % if the underwriters exercise their option to purchase additional shares from the selling stockholder). As a U.S. defense contractor with high level personal and facility security clearances, DRS, US Holding and Leonardo S.p.A. have entered into an agreement with the DoD to mitigate against the potential for undue foreign ownership control and influence (“FOCI”) on the performance of classified programs by implementing various limitations on US Holding’s and Leonardo S.p.A.’s rights as the direct stockholder and ultimate foreign parent company of DRS, respectively. Specifically, US Holding has authorized certain cleared US persons to operate as its proxies and exercise the key prerogatives of stock ownership. The proxy agreement requires that DRS have the financial and operational ability to operate as an independent entity under an independent board of directors, subject to certain limited, enumerated consent rights of the majority stockholder (including material mergers and acquisitions and incurrence of debt). For additional information, see “Certain Relationships and Related Party Transactions—Transactions with Leonardo S.p.A. Affiliates—Proxy Agreement.”

Our Ultimate Parent

Leonardo S.p.A., a global high-technology company, is among the top ten world players in Aerospace, Defense and Security and Italy’s main industrial company. Organized into five business divisions, Leonardo S.p.A. has a significant industrial presence in Italy, the United Kingdom, Poland and the USA, where it also operates through subsidiaries such as Leonardo DRS (defense electronics), and joint ventures and partnerships: ATR, MBDA, Telespazio, Thales Alenia Space and Avio. Leonardo S.p.A. competes in the most important international markets by leveraging its areas of technological and product leadership (Helicopters, Aircraft, Aerostructures, Electronics, Cyber Security and Space). Listed on the Milan Stock Exchange (LDO), in 2019 Leonardo S.p.A. recorded consolidated revenues of €13.8 billion and invested €1.5 billion in Research and Development. The group has been part of the Dow Jones Sustainability Index (“DJSI”) since 2010 and is named as sustainability global leader in the Aerospace & Defense sector of DJSI for the second year in a row in 2020.

The Offering

DRS is a wholly owned subsidiary of US Holding and, indirectly, of Leonardo S.p.A., which operates under a U.S. defense proxy board. We believe this offering will enable us to show the full potential of DRS’s value and provide focused capital allocation to fuel growth. Following this transaction, US Holding will remain a majority stockholder in the Company and will manage its ownership stake in accordance with an amended and restated proxy agreement and a cooperation agreement that will address rights that US Holding and Leonardo S.p.A. will have with respect to business and financial information and financial accounting matters and certain consent rights.

Organizational Structure

After the completion of this offering, we expect that Leonardo S.p.A. will indirectly hold approximately          % of our common stock through US Holding (or       % if the underwriters exercise their option to purchase additional shares from the selling stockholder). As a result, we expect to be a “controlled company” within the meaning of                 rules, following the completion of this offering. This status will allow us to rely on exemptions from certain corporate governance requirements otherwise applicable to listed companies. See “Management—Corporate Governance—Controlled Company.”

RISK FACTORS

Investing in our common stock involves risk. You should consider carefully the risks and uncertainties described below, as well as other information contained in this prospectus, including our financial statements and the section titled “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” before making an investment decision. The risks described below are not the only ones facing us, and are not necessarily presented in the order of importance. The occurrence of any of the following risks or additional risks and uncertainties not presently known to us or that we currently believe to be immaterial could materially and adversely affect our business, financial condition and results of operations. In any such case, the trading price of our common stock could decline, and you could lose all or part of your investment. This prospectus also contains forward-looking statements and estimates that involve risks and uncertainties. Our actual results could differ materially from those anticipated in the forward-looking statements as a result of a number of factors, including the risks and uncertainties described below.

Risks Relating to Our Business

We depend on U.S. defense spending for the vast majority of our revenues. Disruptions or deteriorations in our relationships with the relevant agencies of the U.S. government could have a material adverse impact on our business, financial condition and results of operations.

We depend on revenues from contracts and subcontracts with the U.S. government, including defense-related programs with the DoD and a broad range of programs with all branches of the U.S. military. Revenues derived directly or indirectly from contracts with the U.S. government represented approximately 89% and 86% of our total revenues for the years ended December 31, 2019 and 2018, respectively, with revenues principally derived directly or indirectly from contracts with the U.S. Army and U.S. Navy, which represented 40% and 36%, respectively, of our total revenues for the year ended December 31, 2019. Because our customer base is concentrated within the U.S. defense industry, any disruption or deterioration in our relationship with the U.S. government and its prime contractors, or any change in the U.S. government’s willingness to commit substantial resources to the continued purchase of our products, could significantly reduce our revenues and have a material adverse impact on our business, financial condition and results of operations.

Significant delays or reductions in appropriations for our programs and changes in U.S. government priorities and spending levels more broadly may negatively impact our business and could have a material adverse impact on our business, financial condition and results of operations.

The availability of U.S. government funding for significant programs in which we participate may be impacted by a number of factors beyond our control including the overall federal budget, changes in spending priorities and defense spending levels, sequestration, the appropriations process, use of continuing resolutions (with restrictions, e.g., on starting new programs) and the permissible level of federal debt. These factors may also delay purchasing or payment decisions by our customers. In the event government funding for significant programs in which we participate becomes unavailable, or is reduced or delayed, our contract or subcontract under such programs may be terminated or adjusted by the U.S. government or the prime contractor. U.S. government priorities and spending levels have fluctuated and may continue to fluctuate over time. We cannot predict the impact on existing, follow-on, replacement or future programs from potential changes in priorities whether due to changes in defense spending levels, the threat environment, procurement strategy, military strategy and planning and/or changes in social, economic or political priorities, including in response to the COVID-19 pandemic. The U.S. government may also delay, modify or cancel ongoing competitive bidding processes, procurements and programs, as well as change its acquisition strategy. A significant shift in government priorities, programs or acquisition strategies could have a material adverse impact on our business, financial condition and results of operations.

Considerable uncertainty exists regarding future budget and program decisions, including U.S. defense spending priorities, what challenges budget reductions will present for the defense industry, whether annual appropriations bills for all agencies will be enacted for U.S. government fiscal year 2021 and thereafter, and how the Biden administration will approach those decisions through the budgeting process. The U.S. government’s budget deficit and the national debt could significantly affect government budgeting priorities and could have an adverse impact on our business, financial condition and results of operations in a number of ways, including the following:

•the U.S. government could reduce or delay its spending on, or reprioritize its spending away from, defense programs in which we participate;

•U.S. defense spending could be impacted by alternate arrangements to sequestration, which increases the uncertainty as to, and the difficulty in predicting, U.S. government spending priorities and levels;

•we may experience reduced or delayed orders or payments or other responses to economic difficulties experienced by our customers and prospective customers, including U.S. Federal, state and local governments; and

•the U.S. government could reduce the outsourcing of functions that we are currently contracted to provide, including as a result of increased insourcing by various U.S. government agencies due to changes in the definition of “inherently governmental” work, such as proposals to limit contractor access to sensitive or classified information and work assignments.

The COVID-19 pandemic and related impacts have had and are likely to continue to have an adverse impact on our business, financial condition and results of operations.

In March 2020, COVID-19 was recognized as a pandemic by the World Health Organization and declared a national emergency by the U.S. government. We are closely monitoring the impact of the COVID-19 pandemic on all aspects of our business and geographies, including how it is impacting our workforce, communities, suppliers, subcontractors and customers. The COVID-19 pandemic has created significant volatility, uncertainty and economic disruption, which has adversely affected, and is expected to continue to adversely affect, our business operations, and could materially and adversely affect our business, financial condition and results of operations.

In addition to volatility in the overall demand environment for our products, systems and services, we have restricted the operations in our facilities, and we may continue to restrict operations if we deem it necessary or if recommended or mandated by governmental authorities which would have a further adverse impact on us. For example, we have temporarily closed portions of, and in some cases, entire facilities, including our manufacturing and engineering facility in St. Louis, Missouri for a two-week period, and implemented operational and travel restrictions, which have disrupted how we operate our business. We have also implemented enhanced health leave benefits and incurred other costs related to the COVID-19 pandemic. We incurred approximately $10 million of expenditures from March 1, 2020 through November 30, 2020 to ensure a safe work environment for our employees. Although we offset a portion of the cash impacts from COVID-19 pursuant to Section 3610 of the Coronavirus Aid, Relief and Economic Securities Act (the “CARES Act”), allowing for a deferral of social security payroll tax payments and pension related contributions, we may not be able to fully offset COVID-19 related costs. We are designated as an essential business in the primary jurisdictions in which we operate, but if we lose that designation we may be subject to additional restrictions on our operations. We may be unable to perform fully on our contracts and our costs may increase as a result of the COVID-19 outbreak. These cost increases may not be fully recoverable or adequately covered by insurance. See “Management’s Discussion and Analysis of Financial Condition—Business Overview and Considerations—Impacts of COVID-19 On Our Business.”

The COVID-19 pandemic has the potential to significantly impact our supply chains, including our access to vital products and services we source from suppliers and vendors. Our supply chains could be

17

impacted if the operations of our suppliers, logistics and other service providers are disrupted, temporarily closed or experience worker shortages. In particular, we rely on smaller suppliers for some materials and underlying components needed for our products and these suppliers may be particularly vulnerable to COVID-19 related disruptions. To the extent that there is a slow-down in production from our suppliers, limiting our own production capacity, this could adversely affect our revenues and profit for a reporting period or beyond. Further, the COVID-19 pandemic could cause delay, or limit the ability of the U.S. government and other customers to perform, including in making timely payments to us. Any effect on our suppliers, other service providers and customers could materially adversely impact our business, financial condition and results of operations.

Further, our management is focused on mitigating the effects of COVID-19, which has required and is expected to continue to require, a large investment of time and resources across our enterprise and which may delay other value-added services or initiatives. Additionally, many of our employees are currently working remotely. An extended period of remote work arrangements could strain our business continuity plans, introduce operational and compliance risk, including but not limited to cyber security risks, and impair our ability to manage our business.

The extent to which the COVID-19 pandemic, or any mutation of this virus or a new virus that necessitates a similar national response, will impact us in the future will depend on numerous evolving factors and developments that we are unable to predict, including: the severity and transmission rate of the virus(es); the duration of the outbreak, including the risk of a resurgence of the virus in areas in which it appears to have been contained; the extent and effectiveness of containment actions; governmental, business and other actions (which could include limitations on our operations or mandates to provide products, systems or services); the continued success of measures taken by governmental authorities worldwide to stabilize the markets and support economic growth, which is unknown and may not be sufficient to address future market dislocations or avert severe and prolonged reductions in economic activity; the impacts on our supply chain; the impact of the pandemic on economic activity; the effects of additional business or facility closures or other changes to our operations; the health of and the effect on our workforce and our ability to meet staffing needs in our businesses and facilities, particularly if members of our workforce are quarantined as a result of exposure; any impairment in value of our tangible or intangible assets which could be recorded as a result of a weaker economic conditions; and the potential effects on our internal controls, including those over financial reporting, as a result of remote working environments and other conditions such as shelter-in-place and similar orders that apply to our employees and business partners, among others. In addition, disruptions in the credit or financial markets or impacts on our credit ratings from the pandemic could adversely affect our ability to access capital on favorable terms and continue to meet our liquidity needs, all of which are highly uncertain and cannot be predicted. This situation continues to evolve, sometimes rapidly, and additional impacts may arise that we are not aware of currently.

The impacts of the COVID-19 pandemic may exacerbate other risks described in this section, any of which could have a material adverse impact on our business, financial condition and results of operations.

Our results of operations and cash flows are substantially affected by our mix of fixed-price, cost-plus and time-and-material type contracts. In particular, fixed-price contracts subject us to the risk of loss in the event of cost overruns or higher than anticipated inflation.

We generate revenue through various fixed-price, cost-plus and time-and-material contracts. For a general description of our U.S. government contracts and subcontracts, including a discussion of revenue generated thereunder and of cost-reimbursable versus fixed-price contracts please see “Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

For the years ended December 31, 2019 and 2018, approximately 86% and 82%, respectively, of our revenue was derived from fixed-price contracts. We assume financial risk on fixed-price contracts due to the risk of potential cost overruns, particularly for firm fixed-price contracts in which we assume all of the cost burden. Our failure to anticipate risks or technical problems, estimate costs accurately or control

18

costs during performance will reduce our profit or cause a loss on these contracts. U.S. government contracts can expose us to potentially large losses because the U.S. government can hold us responsible for completing a project or, in certain circumstances, paying the entire cost of its replacement by another provider regardless of the size or foreseeability of any cost overruns that occur over the life of the contract. Because many of these contracts involve new technologies and applications and can last for years, unforeseen events, such as technological difficulties, engineering or development challenges, fluctuations in raw materials prices, higher than expected inflation, increased labor costs, problems with our suppliers and cost overruns, can result in the contractual price becoming less favorable or even unprofitable to us over time. Furthermore, if we do not meet contract deadlines or specifications, we may need to renegotiate contracts on less favorable terms, be forced to pay penalties or liquidated damages or suffer significant losses if the customer terminates our contract. In addition, some of our contracts have provisions relating to cost controls and audit rights, and if we fail to meet the terms specified in those contracts, we may not realize their full benefits. For further information, see “—We operate in a highly regulated environment and are routinely audited and reviewed by the U.S. government and its agencies.” Our results of operations depend on our ability to maximize our earnings from our contracts. Cost overruns could have a material adverse impact on our business, financial condition and results of operations.

We are subject to the U.S. government’s requirements, including the DoD’s National Industrial Security Program Operating Manual, for our facility security clearances, which are prerequisites to our ability to perform on classified contracts for the U.S. government.

We require a facility security clearance to perform on classified contracts for the DoD and certain other agencies of the U.S. government. Security clearances are subject to regulations and requirements including, among others, the National Industrial Security Program Operating Manual (the “NISPOM”), which specifies the requirements for the protection of classified information released or disclosed in connection with classified U.S. government contracts. The Defense Counterintelligence and Security Agency (the “DCSA”) manages the facility clearance process under the NISPOM and conducts various facility audits and inspections throughout the lifecycle of a respective facility clearance.

We require certain facility and personnel security clearances to perform our classified U.S. government business. Any facility not audit ready, not staffed by appropriately cleared personnel, and/or that fails a routine inspection places that contract in jeopardy. As such, we must comply with the requirements of the NISPOM and other applicable U.S. government industrial security regulations, including extensive requirements related to cybersecurity. If we were to violate the terms and requirements of the NISPOM or such industrial security regulations (which apply to us under the terms of classified contracts), or if one or more of our facility or personnel security clearances is invalidated or terminated, we may not be able to continue to perform our existing classified contracts and may not be able to enter into new classified contracts, which could adversely affect our revenues. Failure to comply with the NISPOM or other security requirements may result in loss of access to classified information and subject us to civil and criminal penalties and administrative sanctions, including termination of contracts, forfeiture of profits, suspension of payments, fines and suspension or prohibition from doing business with the U.S. government, which could have a material adverse impact on our business, financial condition and results of operations.

Additionally, the NISPOM requires that a corporation maintaining a facility security clearance be effectively insulated from FOCI. A company is considered to be operating under FOCI whenever a foreign interest has the power, direct or indirect, whether or not exercised, and whether or not exercisable, to direct or decide matters affecting the management or operations of that company in a manner that may result in unauthorized access to classified information, may adversely affect the performance of classified contracts, or may undermine U.S. security or export controls.

Following this offering, Leonardo S.p.A., an Italian company listed on the Milan Stock Exchange, will continue to own the entire share capital of US Holding which, in turn, will beneficially own approximately         % of the voting power of our outstanding common stock (or            % if the underwriters exercise

19

their option to purchase additional shares in full). As a result, we are deemed to be under FOCI. Furthermore, the Italian state beneficially owns approximately 30.2% of Leonardo S.p.A.’s voting power (through its ownership of approximately 30.2% of the outstanding ordinary shares of Leonardo S.p.A.). In order to be permitted to maintain our security clearances and our access to classified data and to perform or bid on classified programs, we are required to mitigate FOCI through a proxy agreement, which we have done by entering into a proxy agreement, dated as of October 26, 2017, with the DoD. Following this offering we expect to enter into an amended and restated proxy agreement and the parties to the proxy agreement have entered into a commitment letter, dated as of         , 2020, as to the form and content of the amended and restated proxy agreement which allows us to operate as if the amended and restated proxy agreement was already in effect. The description of the proxy agreement in this prospectus therefore reflects the terms of the proxy agreement as it will be amended and restated, in accordance with the commitment letter, following this offering. For additional information on the terms and requirements of the proxy agreement, see “—We operate under a proxy agreement with the DoD that regulates significant areas of our governance. If we fail to comply with the proxy agreement our classified U.S. government contracts could be terminated, which could have a material adverse impact on our business, financial condition and results of operations.”

While we currently mitigate FOCI under the proxy agreement, the DoD reserves the right to impose such additional security safeguards as it believes necessary in order to prevent unauthorized access to classified and controlled unclassified information and any U.S. government agency may deny or revoke our access to classified and controlled unclassified information under its jurisdiction if it considers it necessary to protect national security. Failure to maintain an agreement with the DoD regarding the appropriate FOCI mitigation arrangement could result in invalidation or termination of our facility security clearances, which in turn would mean that we would not be able to perform under current or enter into future contracts with the U.S. government requiring facility security clearances.

We depend on revenues from contracts and subcontracts with the U.S. government, including defense-related programs with the DoD and a broad range of programs with each of the service branches. Revenues derived directly or indirectly from contracts with the U.S. government were approximately 89% and 86% for the years ended December 31, 2019 and 2018, respectively. If we fail to maintain an agreement with the DoD regarding the appropriate FOCI mitigation arrangement or otherwise fail to comply with the NISPOM, this could have a material adverse impact on our business, financial condition and results of operations. For further information, see “—We depend on U.S. defense spending for the vast majority of our revenues. Disruptions or deteriorations in our relationships with the relevant agencies of the U.S. government could have a material adverse impact on our business, financial condition and results of operations.”

We depend on U.S. government contracts, which often are only partially funded and are subject to immediate termination. The termination or failure to fund one or more of these contracts could have a material adverse impact on our business, financial condition and results of operations.

Over its lifetime, a U.S. government program may be implemented by the award of many different individual contracts and subcontracts. The funding of U.S. government programs is subject to Congressional appropriations. U.S. government appropriations in turn are affected by general U.S. government budgetary issues and related legislation. Although multi-year contracts may be authorized and appropriated in connection with major procurements, Congress generally appropriates funds on a government fiscal year basis, which runs from October 1 to September 30. Procurement funds are typically made available for obligation over the course of one to three years. Consequently, programs often initially receive only partial funding, and additional funds are obligated only as Congress makes further appropriations. We cannot predict the extent to which total funding and/or funding for individual programs will be included, increased or reduced as part of the annual appropriations process ultimately approved by Congress and the President or in separate supplemental appropriations or continuing resolutions, as applicable. The termination of funding for a U.S. government program would result in a loss of anticipated future revenue attributable to that program, which could have a material adverse impact on our business, financial condition and results of operations. In addition, the termination of a

20

program or the failure to commit additional funds to a program that already has been started could result in lost revenue and increase our overall costs of doing business. The loss of revenues from our possible failure to obtain renewal or follow-on contracts may be significant because we depend on the U.S. government for a significant portion of our revenues. For further information, see “—We depend on U.S. defense spending for the vast majority of our revenues. Disruptions or deteriorations in our relationships with the relevant agencies of the U.S. government could have a material adverse impact on our business, financial condition and results of operations.”

In addition, U.S. government contracts may generally be terminated, in whole or in part, without prior notice at the U.S. government’s convenience upon payment only for work done and commitments made at the time of termination. For some contracts, we are a subcontractor and not the prime contractor, and in those arrangements, the U.S. government could terminate the prime contractor for convenience without regard for our performance as a subcontractor. We can give no assurance that one or more of our contracts will not be terminated under those circumstances. Also, we can give no assurance that we would be able to procure new contracts to offset the revenue or backlog lost as a result of any termination of our contracts. Because a significant portion of our revenue depends on our performance and payment under our contracts, the loss of one or more large contracts could have a material adverse impact on our business, financial condition and results of operations.

In addition to termination for convenience, U.S. defense contracts are generally also terminable for default based on performance. Termination by the U.S. government, or one of its prime contractors, of a contract due to default could in addition to the loss of future revenue obligate us to pay for re-procurement costs in excess of the original contract price, net of the value of work accepted from the original contract, as well as other damages. Termination of a contract due to our default could also impair our reputation and our ability to compete for other contracts which could have a material adverse impact on our business, financial condition and results of operations. Additionally, our U.S. government contracts are heavily regulated and subject to audit and negative audit findings could result in the termination of these or other contracts or the failure to receive future awards, see “—We operate in a highly regulated environment and are routinely audited and reviewed by the U.S. government and its agencies.”

The U.S. government also has the ability to stop work under a contract for a limited period of time for its convenience. It is possible that the U.S. government, or one of its prime contractors, could invoke this ability across a limited or broad number of contracts. In the event of a stop work order, contractors are typically protected by provisions covering reimbursement for costs incurred on the contract to date and for costs associated with the temporary stoppage of work on the contract plus a reasonable fee. However, such temporary stoppages and delays could introduce inefficiencies and result in financial and other damages for which we may not be able to receive full recovery. They could also ultimately result in termination of a contract (or contracts) for convenience or reduced future orders.

We operate in a highly regulated environment and are routinely audited and reviewed by the U.S. government and its agencies.

We depend on U.S. government contracts, which are heavily regulated and subject to audit by the U.S. government and its agencies, such as the Defense Contract Audit Agency (“DCAA”), Defense Contract Management Agency (“DCMA”), the DoD Inspector General, and others. These agencies review performance on government contracts, direct and indirect rates and pricing practices, and compliance with applicable contracting and procurement laws, regulations and standards. They also review compliance with government standards for our business systems and the adequacy of our internal control systems and policies. Negative findings related to our business and accounting systems and financial controls and capability could result in our ineligibility for future cost-plus contracts. Costs ultimately disallowed or found to be improperly allocated to a specific contract will not be reimbursed or must be refunded if already reimbursed. We record contract revenue based on costs on which we expect to be paid after any final audit. However, we do not know the outcome of any future audits and adjustments in advance, and we may be required to reduce our revenue or profits materially upon completion and final negotiation of audits. As a result of certain cost reduction initiatives across our industry, we have

21

experienced and may continue to experience an increased number of audits and/or a lengthened period of time required to close open audits. For example, the thresholds for certain allowable costs in the U.S., including compensation costs, have been significantly reduced; the allowability of other types of costs are being challenged, debated and, in certain cases, modified, all with potentially significant financial costs to the Company.

If an audit uncovers improper or illegal activities, we may be subject to civil and criminal penalties, sanctions, termination of contracts, forfeiture of profits or suspension or debarment from doing business with the U.S. government. Whether or not illegal activities are alleged, the U.S. government has the ability to decrease or withhold certain payments when it deems systems subject to its review to be inadequate, with significant financial impact. In addition, we could suffer serious reputational harm if allegations of impropriety were made against us or our business partners and suppliers.

Additionally, we are reviewed and rated by our government clients on a contract by contract basis. The receipt of a negative review on one contract could cause us reputational harm and adversely affect our ability to win future contracts.

Due to our reliance on government contracts, negative audit findings or reviews for one or more of these contracts could have a material adverse impact on our business, financial condition and results of operations.

We are subject to a number of procurement, international trade, and other rules regulations and requirements related to our industry, our products, and the businesses we operate. If we fail to comply with such rules, regulations or other requirements we may be subject to civil and/or criminal penalties and/or administrative sanctions.

As a U.S. government contractor, we (and our subcontractors and others with whom we do business) must comply with many significant procurement regulations and other specific legal requirements. These regulations and other requirements increase our performance and compliance costs and risks and regularly evolve. New laws, regulations or procurement requirements or changes to current ones (including, for example, evolving and strengthening regulations related to cybersecurity, privacy, recovery of employee compensation costs, counterfeit and/or substitute parts, anti-human trafficking, organizational conflicts of interest, specialty metals and conflict minerals) can significantly increase our costs and risks and negatively affect our results of operations.

If we fail to comply with procurement regulations or other requirements we may be subject to civil and/or criminal penalties and/or administrative sanctions, which may include termination or modification of contracts, forfeiture of profits, suspension of payments, fines and suspension or prohibition from doing business with the U.S. government, any of which could have a material adverse effect on our business, financial condition and results of operations.

We (again, including our subcontractors and others with whom we do business) are also subject to, and expected to perform in compliance with, a vast array of federal laws, regulations and requirements related to our industry, our products and the businesses we operate. These laws and regulations include, but are not limited to, the Anti-Kickback Act, the Arms Export Control Act, including the ITAR, the Communications Act, the Defense Federal Acquisition Regulations, the EAR (which includes anti-boycott provisions), the False Claims Act, the Federal Acquisition Regulation, the FCPA, the Lobbying Disclosure Act, the Procurement Integrity Act, the Truthful Cost or Pricing Data Act, the Foreign Trade Regulations, the Foreign Investment Risk Review Modernization Act, the International Emergency Economic Powers Act, the Trading with the Enemy Act, and Executive Orders and regulations, administered by the U.S. Department of the Treasury, Office of Foreign Assets Control, as well as rules and regulations administered by the U.S. Customs and Border Protection and the Bureau of Alcohol, Tobacco, Firearms and Explosives. While we have implemented compliance programs that are intended to avoid violations of these federal laws, regulations and requirements, given the nature of our operations and the constant evolution of applicable laws, regulations and requirements, we may not be able to prevent future

22

violations. If we are found to have violated such laws, regulations or requirements, we may be subject to reductions of the value of contracts; contract modifications or termination; the withholding of payments from our customer; the loss of export privileges; administrative or civil judgments and liabilities; criminal judgments or convictions, liabilities and consent or other voluntary decrees or agreements; other sanctions; the assessment of penalties, fines, or compensatory, treble or other damages or non-monetary relief or actions; or suspension or debarment.

If we or those with whom we do business do not comply with the laws, regulations and processes to which we are subject or if U.S. government practices or requirements change significantly, including with respect to the thresholds for allowable costs, it could affect our ability to compete and adversely impact our business, financial condition and results of operations.

The U.S. government’s organizational conflict of interest rules could limit our ability to successfully compete for new contracts or may require us to exit or wind down certain existing contracts, any of which could adversely affect our business, financial condition, results of operations and prospects.

Past efforts by the U.S. government to reform its procurement practices have focused, among other areas, on the separation of certain types of work to facilitate objectivity and avoid or mitigate organizational conflicts of interest, and the strengthening of regulations governing organizational conflicts of interest. Organizational conflicts of interest may arise from circumstances in which a contractor has:

•impaired objectivity during performance;

•unfair access to non-public information; or

•the ability to set the “ground rules” for another procurement for which the contractor competes.

A focus on organizational conflicts of interest issues has resulted in legislation and regulations aimed at increasing organizational conflicts of interest requirements, including, among other things, separating sellers of products and providers of advisory services in major defense acquisition programs. These organizational conflicts of interest regulations have led to increased bid protests related to arguments to disqualify or overturn awards based on conflict grounds.

Future legislation and regulations may increase the restrictions in current organizational conflicts of interest regulations and rules. To the extent that organizational conflicts of interest laws, regulations and rules limit our ability to successfully compete for new contracts or task orders with the U.S. government and/or commercial entities, or require us to exit certain existing contracts or wind down certain existing contracts, either because of organizational conflicts of interest issues arising from our business or because companies with which we are affiliated, including Leonardo S.p.A. and its subsidiaries (including US Holding), or with which we otherwise conduct business create organizational conflicts of interest issues for us, our business, financial condition, results of operations and prospects could be materially and adversely affected.

The U.S. government has and may continue to implement initiatives focused on efficiencies, affordability and cost growth and other changes to its procurement practices.

Our industry has experienced, and we expect will continue to experience, significant changes to business practices globally as a result of an increased focus on affordability, efficiencies, business systems, recovery of costs and a reprioritization of available defense funds to key areas for future defense spending. These initiatives and changes to procurement practices may change the way U.S. government contracts are solicited, negotiated and managed, which may affect whether and how we pursue opportunities to provide our products and services to the U.S. government, including the terms and conditions under which we do so. For example, in connection with these cost reduction initiatives the U.S. government is pursuing alternatives to shift additional responsibility and performance risks to the contractor. Changes in procurement practices favoring incentive-based fee arrangements, different award criteria, non-traditional contract provisions and government contract negotiation offers also may affect our

23

results of operations and predictability. The U.S. government has been pursuing and may continue to pursue these and other policies that could negatively impact our profitability and adversely impact our business, financial condition and results of operations.

We use estimates in pricing and accounting for many of our programs, and changes in our estimates could adversely impact our business, financial condition and results of operations.

We enter into forward pricing rate agreements with our U.S. government clients that establish specific direct and indirect rates to be used in pricing all contracts with the applicable government agency for a specified period of time. This requires us to estimate the costs that we will incur in connection with future contracts. Failure to accurately estimate the costs that we will incur including as a result of changes in underlying assumptions, circumstances or estimates may materially reduce our profit or cause a loss on these contracts and adversely impact our business, financial condition and results of operations.

Additionally, accounting for our contracts requires judgment relative to assessing costs, including costs associated with customer-directed delays and reductions in scheduled deliveries, unfavorable resolutions of claims and contractual matters, judgments associated with estimating contract revenue and costs and assumptions for schedule and technical issues. Due to the size, nature and performance period of many of our contracts, the estimation of total revenue and cost at completion is complicated and subject to many variables. For example, we must make assumptions regarding: (i) the length of time to complete the contract because costs also include expected increases in wages and prices for supplies and materials; (ii) whether contracts should be accounted for as having one or more performance obligations based on the goods and services promised to the customer; (iii) incentives or penalties related to performance on contracts in estimating revenue and profit rates, and recording them when there is sufficient information for us to assess anticipated performance; and (iv) estimates of award fees in estimating revenue and profit rates based on actual and anticipated awards. Because of the significance of the judgments and estimation processes involved in accounting for our contracts, materially different amounts could be recorded if we used different assumptions or if the underlying circumstances were to change. Changes in underlying assumptions, circumstances or estimates may adversely impact our business, financial condition and results of operations.

We may not realize the full value of our total estimated contract value or bookings, including as a result of reduction of funding or cancellation of our U.S. government contracts, which could have a material adverse impact on our business, financial condition and results of operations.

Our total backlog consists of funded and unfunded amounts. Funded backlog represents the revenue value of orders for services under existing contracts for which funding is appropriated or otherwise authorized less revenue previously recognized on these contracts. Unfunded backlog represents the revenue value of orders for services under existing contracts for which funding has not been appropriated or otherwise authorized less revenue previously recognized on these contracts. In addition to backlog, we also evaluate estimated potential remaining contract value, which represents unexercised options associated with existing firm contracts and primarily includes options and agreements with existing customers to purchase new services. Estimated potential remaining contract value together with backlog represents total estimated contract value. Lastly, we evaluate bookings which we define as the total value of contract awards received from the U.S. government for which it has appropriated funds and legally obligated such funds to the Company through a contract or purchase order, plus the value of contract awards and orders received from customers other than the U.S. government. As of December 31, 2019, our total estimated contract value was approximately $         million, consisting of approximately $          million of estimated potential remaining contract value and approximately $2,844 million of total backlog, of which $2,547 million was funded, and our bookings were $2,923 million. We historically have not realized all of the revenue included in our total estimated contract value or bookings, and we may not realize all of the revenue included in our total estimated contract value or bookings in the future. There is a higher degree of risk in this regard with respect to estimated potential remaining contract value and unfunded backlog. In addition, there can be no assurance that our total estimated contract value or bookings will result in actual revenue in any particular period. This is because the actual receipt, timing,

24

and amount of revenue under contracts included in total estimated contract value and bookings are subject to various contingencies, including Congressional appropriations, many of which are beyond our control. The actual receipt of revenue from contracts included in total estimated contract value and bookings may never occur or may be delayed because: a program schedule could change or the program could be canceled; a contract’s funding or scope could be reduced, modified, delayed, de-obligated or terminated early, including as a result of a lack of appropriated funds or cost cutting initiatives and other efforts to reduce U.S. government spending and/or the automatic federal defense spending cuts required by sequestration; in the case of funded backlog, the period of performance for the contract has expired or the U.S. government has exercised its unilateral right to cancel multi-year contracts and related orders or terminate existing contracts for convenience or default; in the case of unfunded backlog, funding may not be available or, in the case of estimated potential remaining contract value, our clients may not exercise their options. Our failure to replace canceled or reduced total estimated contract value or bookings could have a material adverse impact on our business, financial condition and results of operations. See “—Wehave unfunded obligations under our pension plans, and we use estimates in accounting for our pension plans and changes in our estimates could adversely affect our financial condition and results of operations.”

Our business may be harmed if we are unable to appropriately manage our inventory.

We are subject to the risk that the inventory we carry may decrease in value over time due to, among other things, changes in customer priorities and needs. Any increase in the level of inventories of finished goods, components and raw materials that we carry, including due to any failure to replace cancelled or reduced backlog or other shortfalls in anticipated sales, may increase our risk of inventory obsolescence and corresponding inventory write-downs and write-offs, and such amounts could be material. If we are unable to appropriately manage our inventory balances it could have a material adverse impact on our business, financial condition and results of operations.

Our working capital requirements and cash flows are extremely variable and subject to fluctuation, which could have a material adverse effect on our business, financial condition and results of operations.

Our working capital requirements and cash flows have historically been, and are expected to continue to be, subject to significant fluctuations. Historically we have had negative cash flows in some quarters of the year, and we expect this pattern to continue in the future. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations.” If we are unable to manage fluctuations in cash flow, it could have a material adverse impact on our liquidity, as well as on our business, financial condition and results of operations. Factors which could result in fluctuations in our working capital and cash flows include:

•the quantity of product and service sales revenue achieved;

•the margins achieved on sales of products and services;

•the timing and collection of receivables;

•the timing and size of inventory and related component purchases;

•the timing of payment on payables and accrued liabilities; and

•the adequacy of our current financing arrangements and access to additional financing.

We cannot predict future capital needs, the sufficiency of our current financing or our ability to obtain additional financing if we need it.

Our operations are capital intensive and we rely heavily on financing, including working capital financing, such as factoring and supply chain financing. We may also enter into other types of financings in the future, including bank and bond financing. Although we believe that our available cash resources,

25

together with our retained earnings, are sufficient to meet our presently anticipated liquidity needs and capital expenditure requirements, we might in the future need to raise additional funds to, among other things:

•fund our operations;

•address fluctuations in cash flow (including negative cash flow periods);

•support more rapid growth of our business;

•develop new or enhanced products and solutions;

•respond to competitive pressures; and

•acquire companies or technologies.

We cannot guarantee that we will continue to be able to extend existing working capital financing on commercially reasonable terms or at all and we might be unable to obtain additional financing, if needed, on terms acceptable to us, if at all. In the past we have been reliant on our parent company for financing. If sufficient funds are not available or are not available on terms acceptable to us, our ability to fund our current operations, fund expansion, take advantage of acquisition opportunities, develop or enhance services or products, or otherwise respond to competitive pressures would be significantly limited. We may be required to obtain the consent of US Holding in order to obtain financing and there is no guarantee that their consent will be granted. See “—Risks Relating to Our Status as a Controlled Company and under the Proxy Agreement—Our ultimate majority stockholder, Leonardo S.p.A., may have interests that are different from, or conflict with, those of our other stockholders, and their significant ownership in us may discourage change of control transactions.” The existing debt obligations of Leonardo S.p.A., which contain restrictions applicable to subsidiaries of Leonardo S.p.A., including us, may also negatively impact our ability to obtain additional financing on terms acceptable to us, if at all. In addition, any decline in the ratings of our corporate credit or any indications from the rating agencies that their ratings on our corporate credit are under surveillance or review with possible negative implications could adversely impact our ability to access capital. These limitations could have a material adverse impact on our business, financial condition and results of operations.

The agreements governing our debt may contain various covenants that limit our ability to take certain actions and also require us to meet financial maintenance tests, and failure to comply with these covenants could have an adverse impact on our business, financial condition and results of operations.

Our financing arrangements may contain restrictions, covenants and events of default that, among other things, require us to satisfy certain financial tests and maintain certain financial ratios and restrict our ability to incur additional indebtedness and to refinance our existing indebtedness. Financing arrangements which we enter into in the future could contain similar restrictions and additionally could require us to comply with similar, new or additional financial tests or to maintain similar, new or additional financial ratios. The terms of our financing arrangements may impose various restrictions and covenants on us that could limit our ability to respond to market conditions, provide for capital investment needs or take advantage of business opportunities by limiting the amount of additional borrowings we may incur. These restrictions may include compliance with, or maintenance of, certain financial tests and ratios and may limit or prohibit our ability to, among other things:

•borrow money or guarantee debt;

•create liens;

•pay dividends or acquire our capital stock;

•make investments and acquisitions;

26

•enter into, or permit to exist, contractual limits on the ability of our subsidiaries to pay dividends to us;

•enter into new lines of business;

•enter into transactions with affiliates; and

•sell assets or merge with other companies.

Various risks, uncertainties and events beyond our control could affect our ability to comply with these restrictions and covenants. Failure to comply with any of the restrictions and covenants that may be in our financing arrangements could result in a default under those arrangements and under other arrangements that may contain cross-default provisions.

A default would permit lenders to accelerate the maturity of the debt under these arrangements and to foreclose upon any collateral securing the debt. Under these circumstances, we might not have sufficient funds or other resources to satisfy all of our obligations. In addition, the limitations imposed by financing agreements on our ability to incur additional debt and to take other actions might significantly impair our ability to obtain other financing.

To service indebtedness and fund other cash needs, we will require a significant amount of cash, and our ability to generate cash depends on many factors beyond our control.

Our ability to pay principal and interest on our anticipated debt obligations and to fund any planned capital expenditures and other cash needs will depend in part upon the future financial and operating performance of our company and our subsidiaries. Prevailing economic conditions and financial, business, competitive, legislative, regulatory and other factors, many of which are beyond our control, will affect our ability to make these payments.

If we are unable to make payments or we are unable to refinance the debt or obtain new financing under these circumstances, we may consider other options, including:

•sales of assets;

•equity offerings;

•reductions or delays of capital expenditures, strategic acquisitions, investments and alliances; or

•negotiations with our lenders to restructure the applicable debt.

Our business may not generate sufficient cash flow from operations, and future borrowings may not be available to us in an amount sufficient, to enable us to pay our anticipated indebtedness or to fund our other liquidity needs. We may need to refinance all or a portion of our anticipated indebtedness on or before maturity. We may not be able to refinance any of our anticipated debt on commercially reasonable terms, or at all.

We face intense competition and may suffer losses if we fail to compete efficiently.

We operate in highly competitive markets and compete with many large, small and mid-tier defense contractors, including, at times, our customers, based on performance, cost, overall value, delivery and reputation. Our competitors continuously seek to expand their business relationships with the U.S. government and will continue these efforts in the future, and the U.S. government may choose to use other contractors. We expect that a majority of the business that we seek will be awarded through competitive bidding. The U.S. government has increasingly relied on certain types of contracts that are subject to multiple competitive bidding processes, including multi-vendor Indefinite Delivery Indefinite Quantity (“IDIQ”), Governmentwide Acquisition Contracts, General Services Administration Schedule and other multi-award contracts, which has resulted in greater competition and increased pricing pressure.

27

Many of our larger competitors have significantly greater financial resources than we do and have more extensive or more specialized engineering, manufacturing and marketing capabilities than we do in some areas, including as a result of substantial industry consolidation, which increased the market share of certain of our competitors and enabled them to take advantage of economies of scale and develop new technologies. These larger competitors may also benefit from supply chain leverage and pricing flexibility, including, in some cases, the ability to price contracts at a loss, due to their size. Larger competitors, for example, may decide to pursue contracts typically won by mid-tier contractors, such as us. Additionally, our smaller competitors may have lower overhead rates than we do, enabling them to compete effectively on pricing against mid-tier contractors such as us. A number of these competitors are also our suppliers and customers. Additionally, some customers, including the DoD, are increasingly purchasing “off the shelf” components from commercial suppliers in lieu of using traditional defense contractors to design and manufacture such items.

We may not be able to continue to win competitively awarded contracts or to obtain task orders under multi-award contracts. Further, the competitive bidding process involves significant cost and managerial time to prepare bids and proposals for contracts that may not be awarded to us or may be split with competitors, as well as the risk that we may fail to accurately estimate the resources and costs required to fulfill any contract awarded to us. The current competitive environment has resulted in an increase of bid protests from unsuccessful bidders, which typically extends the time until work on a contract can begin. Following any contract award, we may experience significant expense or delay, contract modification or contract rescission as a result of our competitors protesting or challenging contracts awarded to us in competitive bidding.

Preferences or set-asides for minority-owned, small and small disadvantaged businesses could impact our ability to be a prime contractor and limit our opportunity to work as a subcontractor on certain governmental procurements.

As a result of the Small Business Administration (“SBA”) set-aside program, the federal government may decide to restrict certain procurements only to bidders that qualify as minority-owned, small, or small disadvantaged businesses. We would not be eligible to perform as a prime contractor on those programs and in general would be restricted to no more than 49% of the work as a subcontractor on those programs. An increase in the amount of procurements under the SBA set-aside program may impact our ability to bid on new procurements as a prime contractor, limit our opportunity to work as a subcontractor or restrict our ability to compete on incumbent work that is placed in the set-aside program.

We depend in part upon our relationships and alliances with industry participants in order to generate revenue, which involves risks and uncertainties.

We rely on the strength of our relationships with other industry participants, including major prime contractors and small businesses, to form strategic alliances and we have entered, and expect to continue to enter, into joint venture, teaming, partnership, subcontractor and other arrangements. These activities involve risks and uncertainties, including the risk that a joint venture or applicable entity fails to satisfy its obligations, which may result in certain liabilities to us from guarantees and other commitments, the challenges in achieving strategic objectives and expected benefits of the business arrangement, the risk of conflicts arising between us and our partners and the difficulty of managing and resolving such conflicts and the business arrangements generally. In some cases, these relationships are subject to exclusivity arrangements which subject us to the risk that we may be forced to forego superior opportunities with a different partner. In addition, particularly where we act as a subcontractor and form teaming arrangements in which we and other contractors bid on particular contracts or programs, we often lack control over fulfillment of a contract and poor performance on the contract could impact our customer relationship, even when we perform as required. If partners in teaming arrangements suffer financial difficulties, face compliance or other reputational issues or fail to comply with the law, we may be adversely affected to the extent we are relying on such partners. Additionally, the U.S. Department of Justice and Federal Trade Commission have periodically and increasingly focused on ensuring competition in government acquisition and could challenge a teaming arrangement. If any of our existing

28

relationships with our industry partners were impaired or terminated, or if we are unable to enter into future arrangements, we could also experience significant delays in the development of new products ourselves, and we would incur additional development costs. We would need to fund these costs internally or identify new industry partners.

Some of our industry partners and major customers are also potential competitors, which may impair the viability of new or continued strategic relationships. This position may create conflicts of interest and uncertainty in circumstances where we continue to operate as both a subcontractor for and a competitor to one of our industry partners or customers, potentially jeopardizing potential revenue opportunities. While we must compete effectively in the marketplace, our future alliances may depend on our industry partners’ perception of us. Our ability to win new and/or follow-on contracts may be dependent upon our relationships within the defense industry.

Contractual disputes with industry participants or the inability of our key suppliers to timely deliver our components, parts or services, could cause our products, systems or services to be produced or delivered in an untimely or unsatisfactory manner.

We act as subcontractor on many contracts and engage subcontractors on many of our own contracts. We may have disputes with our contractual counterparts, including regarding the quality and timeliness of work performed by a subcontractor, customer concerns about a subcontract or subcontractor, our failure to extend existing task orders or issue new task orders under a subcontract, our hiring of personnel of a subcontractor or as a subcontractor or our counterpart’s failure to comply with applicable law. In addition, there are certain parts, components and services for many of our products, systems and services that we source from other manufacturers or vendors. Some of our suppliers, from time to time, experience financial and operational difficulties, which may impair their ability to supply the materials, components, subsystems and services that we require. Impacts from the COVID-19 pandemic have created or exacerbated existing materials shortages, resulted in supplier business closures and disrupted our supply chain. Future impacts from the pandemic remain highly uncertain as the situation continues to evolve, sometimes rapidly. In addition, our supply chain may be disrupted by trade conflicts and tariffs imposed on products, as well as other external events, including natural disasters, extreme weather conditions, future medical epidemics or pandemics, acts of terrorism, cyber attacks and labor disputes, governmental actions and legislative or regulatory changes, such as product certification or stewardship requirements, sourcing restrictions, product authenticity and climate change or greenhouse gas emission standards. These or any further political or governmental developments or health concerns could result in social, economic and labor instability. Any inability to develop alternative sources of supply on a cost-effective and timely basis could materially impair our ability to manufacture and deliver products, systems and services to our customers.

We may have disputes with our subcontractors or suppliers; material supply constraints or problems; or component, subsystems or services problems in the future. Also, our subcontractors and other suppliers may not be able to acquire or maintain the quality of the materials, components, subsystems and services they supply, which might result in greater product returns, service problems and warranty claims and could harm our business, financial condition and results of operations. Further, warranty claims brought by our customers related to third-party components and materials may arise after our ability to bring corresponding warranty claims against such suppliers expire, which could result in costs to us. In addition, in connection with our government contracts, we are required to procure certain materials, components and parts from supply sources approved by the U.S. government and we rely on our subcontractors and suppliers to comply with applicable laws, regulations and other requirements regarding procurement of counterfeit, unauthorized or otherwise non-compliant parts or materials, including parts or materials they supply to us, and in some circumstances, we rely on their certifications as to their compliance. From time to time, we use components for which there is only one supplier and that supplier may be unable to meet our needs. The inability of our suppliers to perform, or their inability to perform adequately, could also result in the need for us to transition to alternate suppliers, which could result in significant incremental cost and delay or the need for us to provide other resources to support

29

our existing suppliers.Each of these subcontractor and supplier risks could have a material adverse impact on our business, financial condition and results of operations.

We are susceptible to a security breach, through cyber attack, cyber intrusion, insider threats or otherwise, and to other significant disruptions of our IT networks and related systems or of those we operate for our customers.

We store sensitive data, including information relating to national security and other sensitive government functions, intellectual property and technology, proprietary business information, and confidential employee information such as personally identifiable or protected health information on our servers and databases. We are subject to laws and rules issued by U.S. and non-U.S. governments and agencies concerning safeguarding and maintaining information confidentiality including extensive and evolving cyber requirements of the DoD. We face the risk of a security breach with respect to that data, whether through cyber attack, cyber intrusion or insider threat via the Internet, malware, computer viruses, attachments to e-mails, persons inside our organization or with access to systems inside our organization, threats to the physical security of our facilities and employees or other significant disruption of our IT networks and related systems or those of our suppliers or subcontractors. The risk of security breaches may be higher during times of a natural disaster or pandemic (including COVID-19) due to remote working arrangements. As an advanced technology-based solutions provider, and particularly as a government contractor with access to national security and other sensitive government information, we face a heightened risk of a security breach or disruption from threats to gain unauthorized access to our and our customers’ proprietary or classified information on our IT networks and related systems and to the IT networks and related systems that we operate and maintain for certain of our customers. These types of information and IT networks and related systems are critical to the operation of our business and essential to our ability to perform day-to-day operations, and, in some cases, are critical to the operations of certain of our customers. We make significant efforts to maintain the security and integrity of these types of information and IT networks and related systems and have implemented various measures to manage the risk of a security breach or disruption. As is the case with many other companies, we have experienced cyber security incidents in the past, including DoS attacks, ransomware, and attacks from suspected nation state actors. Our efforts and measures have not been effective in the case of every incident, but no incident has had a material negative impact on us to date. Sensitive data saved on networks, systems and facilities therefore remain vulnerable because of the risk that cybersecurity incidents, including, but not limited to, attempts to gain unauthorized access to data, potential security breaches, particularly cyber attacks and cyber intrusions, or disruptions, will occur in the future, and because the techniques used in such attempts are constantly evolving and generally are not recognized until launched against a target, and in some cases are designed not to be detected and, in fact, may not be detected. In some cases, the resources of foreign governments may be behind such attacks due to the nature of our business and the industries in which we operate. Accordingly, we may be unable to anticipate these techniques or to implement adequate security barriers or other preventative measures. Thus, it is impossible for us to entirely mitigate this risk, and there can be no assurance that future cyber security incidents will not have a material negative impact on us. A security breach or other significant disruption involving these types of information and IT networks and related systems could:

•disrupt the proper functioning of these networks and systems and, therefore, our operations and/or those of certain of our customers;

•result in the unauthorized access to, and destruction, loss, theft, misappropriation or release of, proprietary, confidential, sensitive or otherwise valuable information of ours, our customers or our employees, including trade secrets, which could be used to compete against us or for disruptive, destructive or otherwise harmful purposes and outcomes;

•result in litigation and governmental investigation and proceedings associated with cybersecurity incidents;

•compromise national security and other sensitive government functions;

30

•require significant management attention and resources to remedy the damages that result;

•result in costs which exceed our insurance coverage and/or indemnification arrangements;

•subject us to claims for contract breach, damages, credits, penalties or termination; and

•damage our reputation with our customers (particularly agencies of the U.S. government) and the general public.

Additionally, a failure to comply with the National Institute of Standards and Technology Special Publication 800-171 or the DoD’s cybersecurity requirements, including the Cyber Security Material Model Certificate (“CMMC”) which will require all contractors to receive specific third-party certifications relating to specified cybersecurity standards in order to be eligible for contract awards, whether or not resulting in a security breach or disruption, could restrict our ability to bid for, be awarded and perform on DoD contracts. The DoD expects that all new contracts will be required to comply with the CMMC by 2026, and initial requests for information and for proposal have already begun. We are in the process of evaluating our readiness and preparing for the CMMC, but to the extent we, or our subcontractors or other third parties on whom we rely, are unable to achieve certification in advance of contract awards that specify the requirement, we will be unable to bid on such contract awards or on follow-on awards for existing work with the DoD, depending on the level of standard as required for each solicitation, which could adversely impact our revenue, business, results of operations and financial condition. We will also be required to go through a recertification process every two years in order to maintain our certification. In addition, any obligations that may be imposed on us under the CMMC may be different from or in addition to those otherwise required by applicable laws and regulations, which may cause additional expense for compliance.

We must also rely on the safeguards put in place by customers, suppliers, vendors, subcontractors, partners in teaming arrangements or other third parties to minimize the impact of cyber threats, other security threats or business disruptions. These third parties may have varying levels of cybersecurity expertise and safeguards, and their relationships with government contractors, such as our company, may increase the likelihood that they are targeted by the same cyber threats, including from foreign governments, we face. In the event of a breach affecting these third parties, our business and financial results could suffer materially. With respect to our commercial arrangements with these third parties, we have processes designed to require that the third parties and their employees and agents agree to maintain certain standards for the storage, protection and transfer of confidential, personal and proprietary information. However, we remain at risk of a data breach due to the intentional or unintentional non-compliance by a third party’s employee or agent, the breakdown of a third party’s data protection processes, which may not be as sophisticated as ours, or a cyber attack on a third party’s information network or systems.

The impact of these various factors is difficult to predict, but any of them could result in the loss of information or capabilities, harm to individuals or property, damage to our reputation, loss of business, contractual or regulatory actions and potential liabilities, any one of which could have a material adverse impact on our business, financial condition and results of operations.

Significant capital investments and other expenditures could be required to remedy cybersecurity problems and prevent future breaches, including costs associated with additional security technologies, personnel and experts. These costs, which could be material, could adversely impact our results of operations in the period in which they are incurred and may not meaningfully limit the success of future attempts to breach our information technology systems.

We may be at greater risk from terrorism and other threats to our physical security and personnel, than other companies.

As a defense contractor, we may be more likely than other companies to be a direct target of, or an indirect casualty of, physical attacks including by active shooters, terrorists or terrorist organizations. It is

31

impossible to predict accurately the likelihood or impact of any attack on our industry generally or on our business. While we have implemented significant physical security protection measures, business continuity plans and established backup sites, in the event of an attack or a threat of an attack, these security measures and contingency plans may be inadequate to prevent significant disruptions in our business, technology or access to the infrastructure necessary to maintain our business. Such attack may harm our personnel, close our facilities or render our backup data and recovery systems inoperable. Damage to our facilities due to attacks may be significantly in excess of any amount of insurance recovery, and we may not be able to insure against such damage at a reasonable price or at all. The threat of attacks may also negatively affect our ability to attract and retain employees. Any of these events could have a material adverse effect on our business, financial condition and results of operations.

Our future success will depend on our ability to respond to the rapid technological changes in the markets in which we compete, our ability to introduce new or enhanced products and to enter into new markets.

The markets in which we compete are characterized by rapid technological developments and frequent new product introductions, enhancements and modifications. Our ability to develop new products and technologies that anticipate changing customer requirements, reduce costs and otherwise retain or enhance our competitive position in existing and new markets will be an important factor in our future results from operations. We will continue to make substantial capital expenditures and incur significant research and development costs aimed at improving our manufacturing capability, reducing costs, and developing and introducing new products and enhancements. If we fail to develop and introduce new products and technologies in a timely manner it could have a material adverse effect on our business, financial condition and results of operations. In addition, we cannot be certain that our new products and technologies will be successful or that customers will accept any of our new products.

Many of our contracts contain performance obligations that require innovative design capabilities, are technologically complex, require state-of-the-art manufacturing expertise or are dependent upon factors not wholly within our control. Failure to meet our contractual obligations could adversely affect our business, financial condition, results of operations, reputation and future prospects.

We design, develop and manufacture technologically advanced and innovative products and services, which are applied by our customers in a variety of environments, including some under highly demanding operating conditions, to accomplish challenging missions. Problems and delays in development or delivery, or system failures, as a result of issues with respect to design, technology, intellectual property rights, labor, inability to achieve learning curve assumptions, inability to manage effectively a broad array of programs, manufacturing materials or components, or subcontractor performance could prevent us from meeting requirements and create significant risk and liabilities. In addition, any obsolescence of components used in our products may require us to redesign our products, in whole or in part, which could cause increased costs. Similarly, failures to perform on schedule or otherwise to fulfill our contractual obligations could negatively affect our reputation and ability to win future business which could have a material adverse impact on our business, financial condition and results of operations.

In addition, our products cannot be tested and proven in all situations and are otherwise subject to unforeseen problems. Examples of unforeseen problems that could negatively affect revenue, schedule and results of operations include premature failure of products that cannot be accessed for repair or replacement, failure to perform in anticipated or unanticipated battlefield conditions, unintended explosions or similar events, problems with design, quality and workmanship, inadequate delivery of subcontractor components or services and degradation of product performance. These failures could result, either directly or indirectly, in loss of life or property. Among the factors that may affect revenue and results of operations could be inaccurate cost estimates, design issues, human factors, unforeseen costs and expenses not covered by insurance or indemnification from the customer, diversion of management focus in responding to unforeseen problems, loss of follow-on work, and, in the case of

32

certain contracts, repayment to the government customer of contract cost and fee payments we previously received, or replacement obligations. See also “—Our results of operations and cash flows are substantially affected by our mix of fixed-price, cost-plus and time-and-material type contracts. In particular, fixed-price contracts subject us to the risk of loss in the event of cost overruns or higher than anticipated inflation.” and “—We use estimates in pricing and accounting for many of our programs, and changes in our estimates could adversely impact our business, financial condition and results of operations.”

If we are unable to meet our obligations, including due to issues regarding the design, development or manufacture of our products or services, it could have a material adverse impact on our reputation, our ability to compete for other contracts and our business, financial condition and results of operations.

We may not be able to fully exploit or obtain patents or other intellectual property protections necessary to secure our proprietary technology.

We seek to protect our competitive position by seeking patents, proprietary information and other intellectual property protections when possible and appropriate. However, we do not have the right to prohibit the U.S. government from using certain technologies developed by us or to prohibit third-party companies, including our competitors, from using those technologies in providing products and services to the U.S. government. The U.S. government often obtains the right to royalty-free use of technologies or intellectual property that we develop under U.S. government contracts or with funding from the U.S. government. Further, while we may retain rights over any technology, product or intellectual property that we develop under U.S. government contracts or using funding from the U.S. government, this requires us to take timely affirmative measures to preserve our rights. We are sometimes able to commercially exploit those government-funded technologies and, in many cases, may assert our intellectual property rights to seek to block other non-government users thereof, but we cannot assure you that we will always have such rights and that when we do, that those efforts will be successful. In some cases it may not be appropriate to patent our intellectual property as this involves making the patented technology public. In such cases we may have limited means to protect our intellectual property.

While we enter into confidentiality and non-disclosure agreements with our employees, consultants, partners, customers and others to attempt to limit access to and distribution of proprietary and confidential information, it is possible that:

•some or all of our confidentiality agreements will not be honored;

•third parties will independently develop equivalent technology or misappropriate our technology or designs;

•disputes will arise with our strategic partners, customers or others concerning the ownership of intellectual property; or

•contractual provisions may not be enforceable in certain jurisdictions.

Also, despite the steps taken by us to protect our proprietary rights, it may be possible for unauthorized third parties to copy or reverse-engineer aspects of our products, develop similar technology independently or otherwise obtain and use information from our supply chain that we regard as proprietary and we may be unable to successfully identify or prosecute unauthorized uses of our technology.

Third parties have claimed in the past and may claim in the future that we are infringing directly or indirectly upon their intellectual property rights, and third parties may infringe upon our intellectual property rights.

Our ability to ensure a competitive market position and gain awards of contracts depends in part on our ability to ensure that our intellectual property is protected, that our intellectual property rights are not

33

diluted or subject to misuse, that we are able to license certain third-party intellectual property on reasonable terms and that we are able to operate without infringing the intellectual property rights of others. Third parties have claimed in the past and may claim in the future that we are infringing directly or indirectly upon their intellectual property rights, and we may be found to be infringing or to have infringed directly or indirectly upon those intellectual property rights. For example, in June 2017 another defense contractor filed suit in the United States Court of Federal Claims alleging that the U.S. government had infringed upon four of its patents relating to night vision weapon systems under a contract awarded to one of our subsidiaries. Neither we nor our subsidiary were named as defendants in the case, and the U.S. government assumes all infringement liability. In 2020, we received a notification from a commercial customer claiming that, under an agreement between us and the customer relating to night vision weapon systems, we would be required to indemnify the customer if it were to incur any costs as a result of these allegations.

Claims of intellectual property infringement might also require us to enter into costly royalty or license agreements. There can be no assurance that any of our patents and other intellectual property will not be challenged, invalidated, misappropriated or circumvented by third parties. Moreover, we may not be able to obtain royalty or license agreements on terms acceptable to us, or at all. We also may be subject to significant damages or injunctions against development and sale of certain of our products, services and solutions. Our success depends in large part on our proprietary technology. We rely on a combination of patents, copyrights, trademarks, trade secrets, know-how, confidentiality provisions and licensing arrangements to establish and protect our intellectual property rights. Our efforts, however, to protect our intellectual property and proprietary rights may not be sufficient. In addition, the laws concerning intellectual property vary among nations and the protection provided to our intellectual property by the laws and courts of foreign nations may differ from and be more limited than the protection provided in the U.S. If we fail to successfully protect and enforce these rights, our competitive position could suffer. Our pending patent and trademark registration applications may not be issued, and/or competitors may challenge the validity or scope of our patents or trademark registrations. In addition, our patents may not provide us a significant competitive advantage. We may be required to spend significant resources to monitor and enforce our intellectual property rights. Litigation to determine the scope of intellectual property rights, even if ultimately successful, could be costly and could divert management’s attention away from other aspects of our business.

Our reputation and ability to do business may be impacted by the improper conduct of our employees, agents, affiliates, subcontractors, suppliers, business partners or joint ventures in which we participate.

We have implemented compliance controls, training, policies and procedures designed to prevent and detect misconduct from being committed by our employees, agents or business partners that would negatively impact our ability to be a U.S. government contractor or subcontractor and/or violate the laws of the jurisdictions in which we operate, including laws governing improper payments to government officials, such as the FCPA, the protection of export-controlled information, such as the ITAR or EAR, false claims, procurement integrity, cost accounting and billing, competition, information security and data privacy and the terms of our contracts. We cannot ensure, however, that our controls, training, policies and procedures will prevent or detect all misconduct. Additionally, we may have limited ability to control the conduct of our affiliates and we have been, and may in the future be, adversely impacted by misconduct of our affiliates. For example, in May 2019 the Italian Supreme Court overturned the 2014 convictions of the former chief executive officer of our ultimate parent, Leonardo S.p.A., and another Leonardo S.p.A. executive, of international bribery. While the convictions in Italy were overturned in a final non-appealable proceeding, the case continues to be the subject of a corruption trial in India. We remain subject to reputational risk as a result of this ongoing action and restrictions on our ability to sell to the Indian government. In addition, in October 2020 an Italian court convicted Alessandro Profumo, the chief executive officer of Leonardo S.p.A., on charges of false statements and market manipulation related to his previous role as chairman of the Italian banking entity, Banca Monte dei Paschi di Siena. While we

34

have been advised by Leonardo S.p.A. that this conviction is going to be appealed, we remain subject to reputational risk as a result of this ongoing proceeding.

This risk of improper conduct may increase as we continue to grow and expand our operations. If not prevented, 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 enforcement actions; monetary and non-monetary penalties; liabilities; and the loss of privileges and other sanctions, including suspension and debarment, which could negatively impact our reputation and ability to conduct business and could have a material adverse impact on our business, financial condition and results of operations. In addition, misconduct involving data security lapses resulting in the compromise of personal information or the improper use of our customers’ sensitive, export-controlled, or classified information could result in remediation costs, regulatory sanctions against us and serious harm to our reputation and could adversely impact our ability to continue to contract with the U.S. government.

We are subject to environmental laws and regulations, and our ongoing operations may expose us to environmental liabilities affecting our reputation, business, financial condition and results of operations.

Our operations are subject to federal, state, foreign and local environmental and health and safety laws and regulations. As a result, we have been involved from time to time in administrative or legal proceedings relating to environmental matters. We cannot assure you that the aggregate amount of future clean-up costs and other environmental liabilities will not be material. We could be subject to potentially significant fines or penalties, including criminal sanctions, if we fail to comply with these requirements. Additionally, we have made and will continue to be required to make significant capital and other expenditures in order to comply with these laws and regulations. The requirements of these laws and regulations are complex, change frequently and could become more stringent in the future. We cannot predict what environmental legislation or regulations will be enacted in the future, how existing or future laws or regulations will be administered or interpreted or what environmental conditions may be found to exist. Our products and services are also used in nuclear-related activities (including providing components for nuclear-powered platforms and sensors used in nuclear applications) and used in support of nuclear-related operations of third parties. Our business also involves the handling, transportation, storage and disposal of potentially dangerous chemicals and unstable materials and is subject to hazards inherent in such activities including chemical spills, storage tank leaks, discharges or releases of toxic or hazardous substances or gases and other hazards incident to the handling, transportation, storage and disposal of dangerous chemicals. Also, in the future, contamination may be found to exist at our current or former facilities or at off-site locations to which we or certain companies that we have acquired or previously owned may have sent waste, and we could be held liable for such contamination. For example, a government site within a national park for which we may be deemed a potentially responsible party has been subject to a government investigation since July 2000. The remediation of such contamination, or the enactment of more stringent laws or regulations or more strict interpretation of existing laws and regulations, may require us to make additional expenditures, and could decrease the amount of free cash flow available to us for other purposes, including capital expenditures, research and development and other investments and could have a material adverse impact on our business, financial condition and results of operations.

Our business, financial condition, and results of operations could be materially adversely affected by climate change regulations.

Climate change regulations at the federal, state, or local level or in international jurisdictions could require us to limit emissions, change our manufacturing processes, obtain substitute materials which may cost more or be less available, increase our investment in control technology for greenhouse gas emissions, fund offset projects, or undertake other costly activities. These regulations could significantly increase our costs and restrict our manufacturing operations by virtue of requirements for new equipment. New permits may be required for our current operations, or expansions thereof. Failure to timely receive

permits could result in fines, suspension of production, or cessation of operations at one or more facilities. In addition, restrictions on carbon dioxide or other greenhouse gas emissions could result in significant costs such as higher energy costs and the passing down of carbon taxes, emission cap-and-trade programs, and renewable portfolio standards by utility companies. The cost of complying, or of failing to comply, with these and other climate change and emissions regulations could have an adverse impact on our business, financial condition and results of operations.

The outcome of litigation, arbitration, investigations, claims, disputes, enforcement actions and other legal proceedings in which we are involved from time to time is unpredictable, and an adverse decision in any such matter could have a material adverse impact on our business, financial condition and results of operations.

The size, nature and complexity of our business make us susceptible to investigations, claims, disputes, enforcement actions, litigation and other legal proceedings, particularly those involving governments. From time to time, we are and may become subject to investigations, claims, disputes, enforcement actions and administrative, civil or criminal litigation, arbitration or other legal proceedings globally and across a broad array of matters, including, but not limited to, government contracts, commercial transactions, false claims, false statements, mischarging, contract performance, fraud, procurement integrity, products liability, warranty liability, the use of hazardous materials, personal injury claims, environmental matters, shareholder-derivative actions, prior acquisitions and divestitures, intellectual property, tax, employees, export/import, anti-corruption, labor, health and safety, accidents, employee benefits and plans, including plan administration, and improper payments, as well as matters relating to our acquisition of assets or companies and other matters. These actions may divert financial and management resources that would otherwise be used to benefit our operations. No assurances can be given that the results of these or any other matters will be favorable to us. Although we maintain insurance policies, these policies may not be adequate to protect us from all material judgments and expenses related to current or future claims and may not cover the conduct that is the subject of the litigation or arbitration. Desired levels of insurance may not be available in the future at economical prices or at all. Although we believe that we have meritorious defenses to the claims made in the litigation matters in which we have been named a party and intend to contest each lawsuit vigorously, no assurances can be given that the results of these matters will be favorable to us. An adverse resolution or outcome of any of these investigations, claims, disputes, enforcement actions, litigation and other legal proceedings could have an adverse impact on our business, financial condition and results of operations.

We cannot predict the outcome of legal proceedings and other contingencies with certainty. As required by U.S. GAAP, we estimate material loss contingencies and establish liabilities based on our assessment of contingencies where liability is deemed probable and reasonably estimable in light of the facts and circumstances known to us at a particular point in time. Subsequent developments may affect our assessment and estimates of the loss contingency recorded as a liability or as a reserve against assets in our financial statements. It is possible that the ultimate resolution of these matters could result in a material adverse impact on our financial condition, results of operations and/or cash flows from operating activities in a particular reporting period.

Our international business exposes us to additional risks, including risks related to geopolitical and economic factors, laws and regulations.

For the years ended December 31, 2019 and 2018, approximately 4% and 6%, respectively, of our revenue was derived from sales to customers located in foreign countries and foreign governments. We cannot assure you that we will maintain significant operations internationally or that any such operations will be successful. International business (including our participation in joint ventures and other joint business arrangements) is subject to numerous political and economic factors, legal requirements, cross-cultural considerations and other risks associated with doing business globally. These risks differ in some respects from those associated with our U.S. business and our exposure to such risks may increase if our international business continues to grow.

36

Our international business is subject to both U.S. and foreign laws and regulations, which may include, without limitation, laws and regulations relating to import-export controls, (such as the ITAR, EAR, and customs laws), tariffs, embargoes, technology transfer restrictions, government contracts and procurement, data privacy and protection, investment, exchange rates and controls, the FCPA and other anti-corruption laws, including the UK Bribery Act and the Canadian Corruption of Foreign Public Officials Act, the anti-boycott provisions under the EAR, U.S. economic sanctions administered by the Office of Foreign Assets Control and other federal agencies, labor and employment, works councils and other labor groups, anti-human trafficking, taxes, environment, immunity, security restrictions and intellectual property. If we or our employees, affiliates, partners or others with whom we work fail to comply with applicable laws and regulations we may be subject to administrative, civil, commercial or criminal penalties and liabilities, including suspension or debarment from government contracts or suspension of our export privileges. Our international business also exposes us to difficulties associated with repatriating cash generated or held abroad in a tax-efficient manner and changes in tax laws. Our customers outside of the U.S. generally have the ability to terminate contracts for default based on performance. Suspension or debarment, or termination of a contract due to default, in particular, could have a material adverse effect on our reputation, our ability to compete for other contracts and our financial position, results of operations and/or cash flows. New regulations and requirements, or changes to existing ones in the various countries in which we operate can significantly increase our costs and risks of doing business internationally. Any such future violations could have a material adverse impact on our reputation, business, results of operations and financial condition.

Changes in laws, regulations, political leadership and environment, or security risks may significantly affect our ability to conduct or continue to conduct business in international markets. Our international business may be impacted by changes in U.S. and foreign national policies and priorities, and geopolitical relationships, any of which may be influenced by changes in the threat environment, political leadership, geopolitical uncertainties, world events, acts of terrorism, bilateral and multi-lateral relationships, government budgets, and economic and political factors more generally, and any of which could impact funding for programs, alter export authorizations, or delay purchasing decisions or customer payments. These changes may affect export control laws as products or markets that were not previously subject to stringent controls may become subject to greater restrictions and oversight. These changes may also affect the defense spending priorities and procurement policies of foreign governments which may affect our international military sales.

Global economic conditions and fluctuations in foreign currency exchange rates could further impact our business. For example, the tightening of credit in financial markets outside of the U.S. could adversely affect the ability of our customers and suppliers to obtain financing and could result in a decrease in or cancellation of orders for our products and services or impact the ability of our customers to make payments. In addition, the majority of our foreign costs are denominated in local currencies. Over time, an increasing portion of our contracts with paid customers outside of the United States may be denominated in local currencies. Therefore, fluctuations in the value of the U.S. dollar and foreign currencies may affect our results of operations when translated into U.S. dollars. We do not currently engage in currency-hedging activities to limit the risk of exchange rate fluctuations. However, in the future, we may use derivative instruments, such as foreign currency forward and option contracts, to hedge certain exposures to fluctuations in foreign currency exchange rates. The use of such hedging activities may not offset any or more than a portion of the adverse financial effects of unfavorable movements in foreign exchange rates over the limited time the hedges are in place. Moreover, the use of hedging instruments may introduce additional risks if we are unable to structure effective hedges with such instruments.

Our contracts with non-U.S. customers may also include terms and reflect legal requirements that create additional risks including the risk of non-payment or delayed payment by foreign customers and governments. They may include industrial cooperation agreements requiring specific in-country purchases, investments, manufacturing agreements or other operational or financial obligations, including offset obligations, and provide for significant penalties if we fail to meet such requirements. They may also require us to enter into letters of credit, performance or surety bonds, bank guarantees and/or other

37

financial arrangements to secure our performance obligations. We also increasingly are dependent on in-country suppliers and we face risks related to their failure to perform in accordance with the contracts and applicable laws, particularly where we rely on a sole source supplier. Our ability to sell products outside the U.S. could be adversely affected if we are unable to design our products for export on a cost-effective basis or to obtain and retain all necessary export licenses and authorizations on a timely basis.

Conducting business outside of the U.S. also exposes us to the complexity and necessity of using, and disruptions involving our international dealers, distributors, sales representatives and consultants as well as the difficulties of managing a geographically dispersed organization and culturally diverse workforces, including compliance with applicable U.S. and local laws and practices, such as anti-corruption and anti-trust/competition laws. Contracts with international customers are significantly different than the contracts with our U.S. customers, and some are more complex and require different skills to manage. Our ability to conduct business outside of the U.S. also depends on our ability to attract and retain sufficient qualified personnel with the skills and/or security clearances in the markets in which we do business.

The products and services we provide internationally, including those provided by subcontractors and joint ventures in which we have an interest, are sometimes in countries with unstable governments, economic or fiscal challenges, military or political conflicts and/or developing legal systems. This may increase the risk to our employees, subcontractors or other third parties, and/or increase the risk of a wide range of liabilities, as well as loss of property or damage to our products.

The occurrence and impact of these factors is difficult to predict, but one or more of them could negatively impact our business, financial condition and results of operations.

We may not be successful in obtaining the export licenses necessary to conduct certain operations abroad, and Congress may prevent proposed sales to certain foreign governments.

We must obtain export and other licenses and authorizations from various U.S. and foreign government agencies before we are permitted to undertake certain activities including selling certain products and technologies outside of the U.S. For example, the U.S. Department of State must notify Congress at least 15 to 30 days, depending on the size and location of the proposed sale, prior to authorizing certain sales of defense equipment and services to some foreign governments. During that time, Congress may take action to block the proposed sale. We can give no assurance that we will continue to be successful in obtaining the necessary licenses or authorizations or that Congress will not prevent or delay certain sales. Additionally, in some cases our ability to source components and products in foreign jurisdictions may require licenses or approvals from foreign governments. Our ability to obtain these licenses and authorizations in a timely fashion or at all is subject to risks and uncertainties, including changing U.S. government policies or laws or delays in Congressional action due to geopolitical and other factors. If we are not successful in obtaining or maintaining the necessary licenses or authorizations in a timely manner, our sales relating to those approvals may be reversed, prevented or delayed, and any significant impairment of our ability to sell products or technologies outside of the U.S. could negatively impact our business, financial condition and results of operations.

A failure to attract and retain technical and other key personnel could reduce our revenues and our operational effectiveness.

Our success depends largely upon the continued services of our executive officers and other key employees. We rely on our leadership team in the areas of research and development, operations, security, marketing, sales, customer experience, general and administrative functions, and on individual contributors in our research and development and operations. In addition, the relationships and reputation that many members of our senior management team have established and maintain with U.S. government personnel contribute to our ability to maintain strong customer relationships and to identify new business opportunities. From time to time, there may be changes in our executive management team resulting from the hiring or departure of executives, which could disrupt our business. We do not have

38

employment agreements with our executive officers or other key personnel that require them to continue to work for us for any specified period and, therefore, they could terminate their employment with us at any time. The loss of one or more of our executive officers, especially our chief executive officer, or key employees could impair our ability to identify and secure new contracts, disrupt customer relations, cause us to be in breach of contracts that require us to maintain key personnel or otherwise harm our business. Changes in our executive management team may also cause disruptions in, and harm to, our business.

There is a high demand for qualified technical and other key personnel, and we believe that our future growth and success will depend upon our ability to attract, train and retain such personnel. Competition for personnel in the defense industry is intense, and there is a limited number of persons with knowledge of and experience in this industry. Additionally, some of our businesses are located in regions where competition for personnel is particularly intense. Although we currently experience manageable rates of turnover for our technical personnel the rate of turnover may increase in the future. Our ability to hire personnel in specific sectors may also be limited by non-disclosure or non-solicit agreements that we have entered into. An inability to attract or maintain a sufficient number of technical and other key personnel could have a material adverse effect on our contract performance or on our ability to capitalize on market opportunities.

Our operating results and growth opportunities are heavily dependent upon our ability to attract and retain sufficient personnel with security clearances and requisite skills in multiple areas, including science, technology, engineering and math. Additionally, as we grow our international business, it is increasingly important that we are able to attract and retain personnel with relevant local qualifications and experience. In addition, in a tightened labor market, we are facing increased competition for talent, both with traditional defense companies and commercial companies. If qualified personnel are scarce or difficult to attract or retain or if we experience a high level of attrition, generally or in particular areas, or if such personnel are unable to obtain security clearances on a timely basis, we could experience higher labor, recruiting or training costs in order to attract and retain necessary employees.

Approximately 480 (or 7%) of our employees are covered by collective agreements which will expire in March and April of 2021. We generally have been able to renegotiate renewals to expiring agreements without significant disruption of operating activities. If we experience difficulties with renewals and renegotiations of existing collective agreements or if our employees pursue new collective representation, we could incur additional expenses and may be subject to work stoppages, slow-downs or other labor-related disruptions. Any such expenses or delays could adversely affect our programs served by employees who are covered by such agreements or representation.

If we are unable to attract and retain a qualified workforce, we may be unable to maintain our competitive position and it could have a material adverse impact on our business, reputation, financial condition and results of operations.

Our business could be harmed in the event of a prolonged work stoppage.

As of October 31, 2020, approximately 480 (or 7%) of our employees were represented by labor unions. If we encounter difficulties with renegotiations or renewals of collective bargaining arrangements or are unsuccessful in those efforts, we could incur additional costs and experience work stoppages. Union actions at our suppliers could also affect us. We cannot predict how stable our union relationships will be or whether we will be able to successfully negotiate successor collective bargaining agreements without impacting our financial condition. In addition, the presence of unions may limit our flexibility in dealing with our workforce. While a relatively small percentage of our employee base is unionized, work stoppages could negatively impact the specific business segments in which our unionized employees are employed including our ability to manufacture products or provide services on a timely basis, which could negatively impact our business, financial condition and results of operations.

Our insurance coverage, customer indemnifications or other liability protections may be unavailable or inadequate to cover all of our significant risks or our insurers may deny coverage of

39

or be unable to pay for material losses we incur, which could adversely affect our business, financial condition and results of operations.

We provide products and services related to hazardous and high-risk operations. Among such operations, our products and services are used in nuclear-related activities (including providing components for nuclear-powered platforms and sensors used in nuclear applications) and used in support of nuclear-related operations of third parties. Our business also involves the handling, transportation, storage and disposal of potentially dangerous chemicals and unstable materials and is subject to hazards inherent in such activities including chemical spills, storage tank leaks, discharges or releases of toxic or hazardous substances or gases and other hazards incident to the handling, transportation, storage and disposal of dangerous chemicals. We endeavor to obtain insurance agreements from financially solid, responsible, highly rated counterparties in established markets to cover significant risks and liabilities (including, for example, natural disasters, hazardous operations and products liability). Not every risk or liability can be insured, and for risks that are insurable, the policy limits and terms of coverage reasonably obtainable in the market may not be sufficient to cover all actual losses or liabilities incurred. Even if insurance coverage is available, we may not be able to obtain it or renew existing coverage at a price or on terms acceptable to us. Disputes with insurance carriers, including over policy terms, reservation of rights, the applicability of coverage (including exclusions), compliance with provisions (including notice) and/or the insolvency of one or more of our insurers may significantly affect the availability or timing of recovery, and may impact our ability to obtain insurance coverage at reasonable rates in the future.

In some circumstances we may be entitled to certain legal protections or indemnifications from our customers through contractual provisions, laws, regulations or otherwise. However, these protections are not always available, can be difficult to obtain, are typically subject to certain terms or limitations, including the availability of funds, and may not be sufficient to cover all losses or liabilities incurred.

If insurance coverage, customer indemnifications and/or other legal protections are not available or are not sufficient to cover our risks or losses, it could have a material adverse impact on our business, reputation, financial condition and results of operations.

We have unfunded obligations under our pension plans, and we use estimates in accounting for our pension plans and changes in our estimates could adversely affect our financial condition and results of operations.

We have unfunded obligations under our pension, postretirement and supplemental retirement plans, see “Note 12: Pension and Other Postretirement Benefits” to the Consolidated Financial Statements. The process of determining the funded status of these plans and our pension plan expense or income involves significant judgment, particularly with respect to our long-term return on pension assets and discount-rate assumptions. If our discount-rate assumption or long-term return on assets (“ROA”) (which is used to determine the funded status of our pension plans) is decreased due to changes in our assumptions or other reasons, our pension plan funded status and expense could increase which would negatively impact our results of operations. In addition, if our actual return on assets differs from our long-term ROA assumption, our pension plan funded status and pension expense would be impacted.

Changes to financial accounting standards may affect our results of operations and cause us to change our business practices.

We prepare our financial statements in accordance with U.S. GAAP. These accounting principles are subject to interpretation by the Financial Accounting Standards Board, the SEC and various bodies formed to interpret and create appropriate accounting policies. A change in these accounting standards or the questioning of current reporting practices may adversely affect our reported financial results or the way we conduct our business.

Changes in future business or other market conditions could cause business investments and/or recorded goodwill or other long-term assets to become impaired, resulting in substantial losses

40

and write-downs that would adversely affect our business, financial condition and results of operations.

As of December 31, 2019, we had goodwill and other intangible assets of $1,126 million, net of accumulated amortization, which represented 39% of our total assets. Our goodwill is subject to an impairment test on an annual basis and is also tested whenever events and circumstances indicate that goodwill may be impaired. Any excess goodwill resulting from the impairment test must be written off in the period of determination. Intangible assets (other than goodwill) are generally amortized over the useful life of such assets. In addition, from time to time, we may acquire or make an investment in a business which will require us to record goodwill based on the purchase price and the value of the acquired assets. We may subsequently experience unforeseen issues with such business which adversely affect the anticipated returns of the business or value of the intangible assets and trigger an evaluation of the recoverability of the recorded goodwill and intangible assets for such business. Future determinations of significant write-offs of goodwill or intangible assets as a result of an impairment test or any accelerated amortization of other intangible assets could have a negative impact on our results of operations and financial condition.

Our ability to use our net operating losses to offset future taxable income may be subject to certain limitations.

In general, under Section 382 of the U.S. Internal Revenue Code of 1986, as amended (the “Tax Code”), a corporation that undergoes an “ownership change” is subject to limitations on its ability to utilize its pre-change net operating losses (“NOLs”) to offset future taxable income. Future changes in our stock ownership, some of which are beyond our control, could result in an ownership change under Section 382 of the Tax Code. Furthermore, our ability to utilize NOLs of any companies that we may acquire in the future may be subject to limitations. For these reasons, we may not be able to utilize a material portion of the NOLs reflected on our balance sheet, even if we attain profitability.

We could be liable for certain tax liabilities, including tax liabilities of US Holding and its subsidiaries, under tax law and the tax allocation agreement.

In connection with this offering, we and US Holding have entered into a tax allocation agreement with members of an affiliated group, as defined in Section 1504(a) of the Tax Code, members of one or more consolidated, combined, unitary or similar state tax groups and additional parties who are part of an “expanded affiliated group” for certain tax purposes. Under the tax allocation agreement, we are responsible for U.S. federal and state tax liability attributable to us or any of our subsidiaries, as determined under the tax allocation agreement, for prior taxable periods beginning with the first consolidated taxable year of US Holding that included DRS (i.e., the taxable year ended December 31, 2008) and for future taxable periods in which we are a member of any consolidated, combined or unitary tax return with US Holding or its subsidiaries. In addition, to the extent US Holding fails to pay taxes imposed with respect to any consolidated, combined or unitary tax return of US Holding or any of its subsidiaries that includes us or any of our subsidiaries, the relevant taxing authority could seek to collect such taxes (including taxes for which US Holding or any of its subsidiaries is responsible under the tax allocation agreement) from us or our subsidiaries. For a description of the tax allocation agreement, see “Certain Relationships and Related-Party Transactions—Relationship with Leonardo S.p.A. Following this Offering—Tax Allocation Agreement.”

Acquisitions could result in operating difficulties, dilution and other harmful consequences.

We have evaluated in the past, and expect to continue to evaluate in the future, potential strategic transactions. Any of these transactions could be material to our financial condition and results of

41

operations. The acquisition and the integration of an acquired company, business or technology may create unforeseen operating difficulties and expenditures and involves risks, including:

•the need to implement or remediate controls, procedures, policies and compliance programs appropriate for a larger public company at companies that prior to the acquisition lacked these controls, procedures and policies;

•diversion of management time and focus from operating our business to acquisition integration challenges;

•cultural challenges associated with integrating employees from the acquired company into our organization;

•retaining employees and customers from the businesses we acquire;

•the need to integrate each company’s accounting, management information, human resource and other administrative systems to permit effective management; and

•litigation related to acquisitions.

Foreign acquisitions involve unique risks in addition to those mentioned above, including those related to integration of operations across different cultures and languages, currency risks and the particular economic, political and regulatory risks associated with specific countries.

In addition, the anticipated benefit of many of our acquisitions may not materialize. Future acquisitions or dispositions could result in potentially dilutive issuances of our equity securities, the incurrence of debt, contingent liabilities or amortization expenses, or write-offs of goodwill, any of which could harm our financial condition and results of operations. Future acquisitions may require us to obtain additional equity or debt financing, which may not be available on favorable terms or at all.

Finally, we may be required to obtain the consent of US Holding in order to pursue certain material transactions and there is no guarantee that their consent will be granted See “—Risks Relating to Our Status as a Controlled Company and under the Proxy Agreement—Our ultimate majority stockholder, Leonardo S.p.A., may have interests that are different from, or conflict with, those of our other stockholders, and their significant ownership in us may discourage change of control transactions.”

We have significant operations in locations that could be materially and adversely impacted in the event of a natural disaster or other significant disruption.

Our operations and the operations of our suppliers and customers could be subject to natural disasters or other significant disruptions, including hurricanes, typhoons, tsunamis, floods, earthquakes, fires, water shortages, other extreme weather conditions, medical epidemics, pandemics (including COVID-19), acts of terrorism, power shortages and blackouts, telecommunications failures and other natural and manmade disasters or disruptions. We have significant business operations located in areas that are subject to these risks, for example our facilities in Florida and Texas. In the event of such a natural disaster or other disruption, we could experience disruptions or interruptions to our operations or the operations of our suppliers, subcontractors, distributors, resellers or customers, including inability of employees to work; destruction of facilities; and/or loss of life, all of which could materially increase our costs and expenses, delay or decrease orders and revenue from our customers and have a material adverse impact on our business, financial condition and results of operations.

Our leases may be terminated or we may be unable to renew our leases on acceptable terms and if we wish to relocate, we may incur additional costs if we terminate a lease.

We have made significant capital expenditures to improve several of our leased facilities in order to make them suitable for our purposes as well as to meet requirements that we are subject to as a U.S. government contractor and obtain facility security clearances. However, at the end of the lease term and

42

during any renewal period for a facility, we may be unable to renew the lease without substantial additional cost, if at all. If we are unable to renew our facility leases, we may close or relocate a facility, which could subject us to construction and other costs and risks, which in turn could have a material adverse effect on our business, financial condition and results of operations, including significant capital expenses that may materially impact our results of operations and ability to meet certain contractual schedule commitments. Additionally, we may have to seek qualification of any new facilities in order to meet customer or contractual requirements. We would also have to obtain facility security clearances for the new facility in order to continue to perform on classified contracts. Further, we may not be able to secure a replacement facility in a location that is as commercially viable as that of the lease we are unable to renew, due to contracts that may require us to have facilities in certain locations. Having to close a facility, even briefly to relocate, would reduce the sales that such facility would be able to contribute to our revenues. Additionally, a relocated facility may generate less revenue and profit, if any, than the facility it was established to replace.

Additionally, many of our facilities are located on leased premises subject to non-cancellable leases. Typically, our leases have initial terms ranging from five to 20 years, with options to renew for specified periods of time. We believe that our future leases will likely also be long-term and non-cancellable and have similar renewal options. If we close or stop fully utilizing a facility, we will most likely remain obligated to perform under the applicable lease, which would include, among other things, making the base rent payments, and paying insurance, taxes and other expenses on the leased property for the remainder of the lease term. Our inability to terminate a lease when we stop fully utilizing a facility could negatively impact our business, financial condition and results of operations.

We cannot predict the consequences of future geo-political events, but they may adversely affect the markets in which we operate, our ability to insure against risks, our operations or our results of operations.

Ongoing instability and current conflicts in global markets, including in the Middle East and Asia, and the potential for other conflicts and future terrorist activities and other recent geo-political events throughout the world, including new or increased tariffs and potential trade wars have created and continue to create economic and political uncertainties and impacts that could have a material adverse impact on our business, financial condition and results of operations. These matters cause uncertainty in the world’s financial and insurance markets and may significantly increase the political, economic and social instability in the geographic areas in which we operate. Such instability and any resulting changes in laws, regulations or security risks may dramatically affect our ability to conduct or continue to conduct business in the impacted international markets. If credit in financial markets outside of the U.S. tightened, it could adversely affect the ability of our customers and suppliers to obtain financing and could result in a decrease in or cancellation of orders for our products, systems and services or impact the ability of our customers to make payments. These matters may cause us to incur increased costs or experience difficulty with future borrowings under our credit facilities or in the debt capital markets, future issuances of common stock or other equity securities or otherwise with financing our operating, investing (including any future acquisitions) or financing activities. These matters also may cause our insurance coverages to increase in cost, or in some cases, to be unavailable altogether.

Risks Relating to Our Status as a Controlled Company and under the Proxy Agreement

We operate under a proxy agreement with the DoD that regulates significant areas of our governance. If we fail to comply with the proxy agreement our classified U.S. government contracts could be terminated, which could have a material adverse impact on our business, financial condition and results of operations.

Following this offering, Leonardo S.p.A., an Italian company listed on the Milan Stock Exchange, will continue to own the entire share capital of our immediate parent US Holding which, in turn, will beneficially own approximately           % of the voting power of our outstanding common stock (or          % if the underwriters exercise their option to purchase additional shares in full). As a result, we are deemed

43

to be controlled by a foreign company and to be under FOCI, as defined in the NISPOM, which establishes procedures and requirements for government contractors, such as our company, with regard to classified information. See “—Risks Relating to Our Business—We are subject to the U.S. government’s requirements, including the DoD’s National Industrial Security Program Operating Manual, for our facility security clearances, which are prerequisites to our ability to perform on classified contracts for the U.S. government.” Furthermore, the combination of the Italian state beneficially owning approximately 30.2% of Leonardo S.p.A.’s voting power (through its ownership of approximately 30.2% of the outstanding ordinary shares of Leonardo S.p.A.), and the governance of Leonardo S.p.A. itself, has led DRS to be deemed to be controlled by a foreign government by certain U.S. regulatory authorities. In order to be permitted to maintain our security clearances and our access to classified data and to perform or bid on classified programs, we are required to mitigate FOCI through a proxy agreement. We have therefore entered into a proxy agreement, dated as of October 26, 2017, with the DoD. Following this offering, we expect to enter into an amended and restated proxy agreement and the parties to the proxy agreement have entered into a commitment letter, dated as of             , 2020, as to the form and content of the amended and restated proxy agreement which allows us to operate as if the amended and restated proxy agreement were already in effect. The description of the proxy agreement in this prospectus therefore reflects the terms of the proxy agreement as it will be amended and restated, in accordance with the commitment letter, following this offering. Among other things, the proxy agreement:

•provides that the shares of our common stock owned directly by US Holding and indirectly by Leonardo S.p.A. are voted through proxy holders, who must be independent from current and prior affiliation with Leonardo S.p.A. and its subsidiaries (including US Holding and us) (subject to limited exceptions) and must maintain adequate security clearance;

•provides that the proxy holders are appointed by our immediate parent US Holding (in consultation with Leonardo S.p.A.)., but the appointment is subject to approval of the DCSA, an agency of the DoD, and that the proxy holders must be members of our board of directors;

•restricts our ability to share facilities and personnel with and receive certain services from any Leonardo S.p.A. or its other subsidiaries;

•requires us to maintain a government security committee of our board of directors; and

•regulates meetings, visits and communications that are not deemed to be routine business visits between us and Leonardo S.p.A. or its other subsidiaries (including US Holding).

Compliance with the proxy agreement requires a significant commitment of resources and management and board oversight, and the DoD may impose additional security safeguards that it believes necessary to adequately safeguard classified and controlled unclassified information, which could make it more difficult for us to comply with the proxy agreement. Under the proxy agreement we are required to prepare and submit an annual implementation and compliance report to the DCSA including detailed information with respect to the manner in which we comply with the proxy agreement including with respect to classified information, any acts of noncompliance and other matters specified by DCSA. We are subject to regular audits of our FOCI compliance and have at times been found to not have strictly complied with our proxy agreement or relevant security requirements but have not to date been sanctioned for any such noncompliance. Additionally, the restrictions imposed by the proxy agreement on our communications and ability to share facilities, personnel and services with Leonardo S.p.A. or its other subsidiaries mean that we cannot benefit from the full range of synergies and cost savings typically enjoyed by a majority-owned subsidiary.

In the event of a material breach of the proxy agreement, the DoD may (i) novate our classified contracts to a company not under FOCI at our expense, (ii) terminate our classified contracts and deny us new classified contracts, (iii) revoke our facility security clearance and/or (iv) suspend or debar us from participation in all U.S. government contracts. We depend on revenues from contracts and subcontracts with the U.S. government, including defense-related programs with the DoD and a broad range of

44

programs with the U.S. Army and U.S. Navy. See “—Risks Relating to Our Business—We depend on U.S. defense spending for the vast majority of our revenues. Disruptions or deteriorations in our relationships with the relevant agencies of the U.S. government could have a material adverse impact on our business, financial condition and results of operations.” Therefore, if we fail to comply with the terms of the proxy agreement and the DoD imposes any of the above remedies, this could have a material adverse impact on our business, financial condition and results of operations. For further information about the proxy agreement, see “Certain Relationships and Related-Party Transactions—Relationship with Leonardo S.p.A. Following this Offering—Proxy Agreement.”

CFIUS may modify, delay or prevent our future acquisition or investment activities.

We are considered a “foreign person” under the regulations administered by CFIUS and will continue to be considered as such in the future for so long as Leonardo S.p.A. has the ability to exercise control over us for purposes of CFIUS’s regulations. As such, acquisitions of or investments in U.S. businesses or foreign companies with U.S. businesses that we may wish to pursue may be subject to CFIUS review, the scope of which was recently expanded by the Foreign Investment Risk Review Modernization Act of 2018 (“FIRRMA”), to include certain non-passive, non-controlling investments in sensitive U.S. businesses and certain acquisitions of real estate even with no underlying U.S. business. FIRRMA, and subsequent implementing regulations that are now in force, also subjects certain categories of investments to mandatory filings. If a particular proposed acquisition or investment in a U.S. business falls within CFIUS’s jurisdiction, we may determine that we are required to make a mandatory filing or that we will submit a voluntary notice to CFIUS, or to proceed with the transaction without notifying CFIUS and risk CFIUS intervention, before or after closing the transaction. CFIUS may decide to block or delay an acquisition or investment by us, impose conditions to mitigate national security concerns with respect to such acquisition or investment or order us to divest all or a portion of a U.S. business that we acquired without first obtaining CFIUS clearance, which may limit the attractiveness of or prevent us from pursuing certain acquisitions or investments that we believe would otherwise be beneficial to us and our stockholders. We may therefore be adversely affected in terms of competing with other companies in our industry which do not have similar foreign ownership issues. Furthermore, because the Italian state beneficially owns approximately 30.2% of the voting power of the outstanding ordinary shares of, and exercises certain governance rights over, Leonardo S.p.A. (through its ownership of approximately 30.2% of Leonardo S.p.A.’s ordinary shares), which in turn has the ability to exercise control over us for purposes of CFIUS’s regulations, we are considered to be foreign government controlled under the regulations administered by CFIUS. Foreign-government-controlled investors may be subject to a higher level of CFIUS scrutiny than non-foreign-government-controlled investors. Additionally, future foreign investments in us could be within the jurisdiction of CFIUS and, given the nature of our business, may trigger a mandatory CFIUS notification requirement or warrant voluntary notification to CFIUS, impacting our ability to attract such investment. Further, CFIUS may decide to block, delay, or impose material conditions on any such future foreign investment in us that it reviews.

Because we are deemed to be controlled by a foreign company, we are required to mitigate FOCI through our proxy agreement. See “Certain Relationships and Related-Party Transactions—Relationship with Leonardo S.p.A. Following this Offering—Proxy Agreement.”

Our ultimate majority stockholder, Leonardo S.p.A., may have interests that are different from, or conflict with, those of our other stockholders, and their significant ownership in us may discourage change of control transactions.

The proxy agreement provides that the shares of our common stock owned directly by US Holding and indirectly by Leonardo S.p.A. are voted through proxy holders, who must be independent from current and prior affiliation with Leonardo S.p.A. and its subsidiaries (including US Holding and us) (subject to limited exceptions) and must maintain adequate security clearance. The proxy holders have the right to vote US Holding’s shares of our common stock in the same manner and to the same extent as if they were the absolute owners of such shares in their own right. In exercising their power as proxy holders, the proxy holders are directed to act to protect the legitimate economic interests of our

45

shareholders and in a manner consistent with their fiduciary duties, but they are not generally required to follow instructions of Leonardo S.p.A., US Holding or us.

The proxy agreement provides that the proxy holders may vote for or consent to in, their sole and absolute discretion, without consultation with US Holding or Leonardo S.p.A., the election of additional directors who are not proxy holders (and who are selected from candidates proposed by US Holding after reasonable consultation with our nominating and corporate governance committee, and subject to DCSA’s approval in certain circumstances), any changes or amendments to our certificate of incorporation or by‑laws, the sale or disposal of our property, assets or business, our incurrence of debt or any pledge, mortgage or encumbrance of any of our assets, or any other matter affecting us, other than as described below.

However, the proxy holders may only vote for or consent to, with the express written approval of US Holding:

•the sale or disposition of any of our subsidiaries, property, assets or business or those of our subsidiaries or the purchase by us or our subsidiaries of any business, properties, assets or entities, other than in the ordinary course of business, in any individual transaction where our investment (based on our share of the enterprise value) exceeds two percent (2%) of our revenues for the immediately preceding year or where our investment, in the aggregate for all such sales or dispositions in a calendar year, exceeds an amount equal to five percent (5%) of our revenues for the immediately preceding year;

•the incurrence of debt or pledge, mortgage, lease or other encumbrance of our assets of those of our subsidiaries in connection with the incurrence of debt if such incurrence would cause the aggregate outstanding principal amount of all debt of us and our subsidiaries to exceed a target leverage ratio (currently set at       x) set forth in our then-current operating plan, excluding current debt incurred for purposes of funding day-to-day working capital requirements in the ordinary course of business;

•any merger, consolidation, reorganization or dissolution of us of any of our subsidiaries except as permitted above and excluding transactions solely among our wholly owned subsidiaries; and

•the filing or making of any petition by us or our subsidiaries under the federal bankruptcy laws or any similar law or statute of any state or any foreign country.

In addition, the proxy holders may only vote to declare or suspend dividends after prior consultation with US Holding.

Conflicts of interest may arise between our majority stockholder and us. Affiliates of our majority stockholder engage in transactions with us. Further, Leonardo S.p.A. and its affiliates may, from time to time, acquire and hold interests in businesses that compete directly or indirectly with us, and they may either directly, or through affiliates, also maintain business relationships with companies that may directly compete with us. In general, Leonardo S.p.A. or its affiliates could pursue business interests that are detrimental to us but beneficial to themselves or to other companies in which they invest or with whom they have a material relationship. Conflicts of interest could also arise with respect to business opportunities that could be advantageous to Leonardo S.p.A., and they may pursue acquisition opportunities that may be complementary to our business. As a result, those acquisition opportunities may not be available to us. Under the terms of our amended and restated certificate of incorporation, neither Leonardo S.p.A. nor US Holding will have an obligation to offer us corporate opportunities.

As a result of these relationships the interests of our ultimate parent, Leonardo S.p.A., may not coincide with our interests or the interests of the other holders of our common stock. So long as Leonardo S.p.A. continues to indirectly control a significant amount of the outstanding shares of our common stock, Leonardo S.p.A. and the proxy holders will continue to be able to strongly influence or effectively control our decisions, including potential mergers or acquisitions, asset sales and other significant corporate

46

transactions. This influence, including the requirement in our proxy agreement for approval by the proxy holders and our majority stockholder of mergers and consolidations, may also discourage change of control transactions.

Following this offering, we expect to be a “controlled company” within the meaning of the                   rules and, as a result, we will qualify for exemptions from certain corporate governance requirements. You may not have the same protections afforded to stockholders of companies that are subject to such requirements.

Following this offering, we expect to be a “controlled company” within the meaning of the                corporate governance standards. Under these rules, a company of which more than 50% of the voting power is held by an individual, group or another company is a “controlled company” and may elect not to comply with certain                       corporate governance standards, including:

•the requirement that a majority of the Board consist of independent directors;

•the requirement that we have a compensation committee that is composed entirely of independent directors with a written charter addressing the committee’s purpose and responsibilities;

•the requirement that our nominating and corporate governance committee be composed entirely of independent directors with a written charter addressing the committee’s purpose and responsibilities, or otherwise have director nominees selected by vote of a majority of the independent directors; and

•the requirement for an annual performance evaluation of the nominating and corporate governance and compensation committees.

While we do not currently intend to use these exemptions, we may in the future decide to do so. Consequently, you may not be entitled to the same protections afforded to stockholders of companies that are subject to all of the                   corporate governance rules and requirements. Our status as a controlled company could make our common stock less attractive to some investors or otherwise harm our stock price.

Our amended and restated certificate of incorporation will provide that we will waive any interest or expectancy in corporate opportunities presented to Leonardo S.p.A.

Our amended and restated certificate of incorporation will provide that we, on our behalf and on behalf of our subsidiaries, renounce and waive any interest or expectancy in, or in being offered an opportunity to participate in, corporate opportunities that are from time to time presented to Leonardo S.p.A., or its officers, directors, agents, stockholders, members, partners, affiliates or subsidiaries, with the exception of the proxy holders, even if the opportunity is one that we or our subsidiaries might reasonably have pursued or had the ability or desire to pursue if granted the opportunity to do so. None of Leonardo S.p.A. or its agents, stockholders, members, partners, affiliates or subsidiaries, with the exception of the proxy holders, will generally be liable to us or any of our subsidiaries for breach of any fiduciary or other duty by reason of the fact that such person pursues, acquires or participates in such corporate opportunity, directs such corporate opportunity to another person or fails to present such corporate opportunity, or information regarding such corporate opportunity, to us or our subsidiaries. To the fullest extent permitted by law, by becoming a stockholder in our company, stockholders will be deemed to have notice of and consented to this provision of our amended and restated certificate of incorporation. This will allow Leonardo S.p.A. and its affiliates to compete with us. Strong competition for investment opportunities could result in fewer such opportunities for us. We likely will not always be able to compete successfully with our competitors and competitive pressures or other factors may also result in significant price competition, particularly during industry downturns, which could have a material adverse impact on our business, financial condition and results of operations.

47

If US Holding sells a controlling interest in our company to a third party in a private transaction, you may not realize any change of control premium on shares of our common stock and we may become subject to the control of a presently unknown third party.

Upon the expiration of                months following this offering, US Holding will have the ability, should it choose to do so, to sell some or all of its shares of our common stock in a privately negotiated transaction. If such a transaction were to be sufficient in size, it could result in a change of control of DRS. The ability of US Holding to privately sell such shares of our common stock, with no requirement for a concurrent offer to be made to acquire all of the shares of our common stock that will be publicly traded hereafter, could prevent you from realizing any change-of-control premium on your shares of our common stock that may otherwise accrue to US Holding upon its private sale of our common stock. Additionally, if US Holding privately sells a significant equity interest in us, we may become subject to the control of a presently unknown third party. Such third party may have conflicts of interest with the interests of other stockholders. For additional information on the tax implications of a change in ownership, see “—Risks Relating to Our Business—Our ability to use our net operating losses to offset future taxable income may be subject to certain limitations.”

Following this offering, we will continue to be obligated to provide certain services to Leonardo S.p.A., which may divert human and financial resources from our business, and to rely on provision of certain services from Leonardo S.p.A., which we may be unable to replicate should the need arise.

Although we operate largely independently from Leonardo S.p.A. and the proxy agreement contains limitations on services that we may provide to and receive from Leonardo S.p.A. and its affiliates, we have historically provided, and expect to continue to provide, certain services to Leonardo S.p.A. and its affiliates to support its U.S. operations (aside from us) and have historically received and expect to continue to receive certain services from Leonardo S.p.A., including services related to group training support, subject in all cases to the proxy agreement. Following this offering, we will continue to provide or procure certain services to or from Leonardo S.p.A. and its affiliates and Leonardo S.p.A. and its affiliates will continue to provide or procure certain services to or from us pursuant to the tax allocation agreement and existing Affiliated Operations Plan (“AOP”) services agreements which will continue pursuant to the terms of such contracts. The tax allocation agreement will remain in effect until terminated upon the written agreement of the parties.

Under our existing AOP services agreements we will continue to provide Leonardo S.p.A. and its affiliates with services in support of its U.S. operations (aside from us), including services related to tax, financial and accounting support, legal support, trade compliance, marketing, communications, media and advertising, and security, on an arm’s-length basis. Under the tax allocation agreement, we are responsible for administering certain U.S. federal and state tax matters on behalf of Leonardo S.p.A. and its subsidiaries (including US Holding). The provision of such services may divert human and financial resources from focus on our business, and may expose us to additional risks and liabilities. Under our existing AOP services agreements, Leonardo S.p.A. and its affiliates will continue to provide us with services, including services related to group training support. We will work to replicate or replace these services; however we cannot assure you that we will be able to obtain the services at the same or better levels or at the same or lower costs directly from third-party providers. As a result, when Leonardo S.p.A. or its affiliates cease providing these services to us, either as a result of the termination of the relevant agreements or individual services thereunder or a failure by Leonardo S.p.A. or its affiliates to perform their respective obligations under these agreements, our costs of procuring these services or comparable replacement services may increase.

We will have obligations in favor of Leonardo S.p.A. after this offering.

We and Leonardo S.p.A. are party to, or will enter into, certain agreements, including a cooperation agreement, registration rights agreement, trademark license agreement, a tax allocation agreement and our existing AOP services agreements, that will govern our and Leonardo S.p.A.’s obligations to one

48

another following this offering in respect of, among other things, taxes, financial and transition services, information sharing and our respective indemnification obligations. The amounts payable by us pursuant to such indemnification obligations could be significant. Under the registration rights agreement, US Holding will have the right to require us to register shares of common stock for resale in some circumstances. For additional information on the potential risks of resale, see “—Risks Relating to Our Common Stock and This Offering—Future sales of shares by existing stockholders could cause our stock price to decline.” Under the cooperation agreement, among other things, Leonardo S.p.A . and US Holding will be entitled to certain consent rights, and we will be required to provide Leonardo S.p.A. with information and data relating to our and our subsidiaries’ business and financial results and reasonable access to our personnel, data and systems. Satisfying our obligations to Leonardo S.p.A. under these agreements may require a significant commitment of resources and management oversight.

Risks Relating to Our Common Stock and This Offering

We will incur increased costs and obligations as a result of being a public company.

As a privately held company, we were not required to comply with certain corporate governance and financial reporting practices and policies required of a publicly traded company. As a publicly traded company, we will incur significant legal, accounting and other expenses that we were not required to incur in the recent past. After this offering, we will be required to file with the SEC annual and quarterly information and other reports that are specified in Section 13 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). We will also be required to ensure that we have the ability to prepare financial statements that are fully compliant with all SEC reporting requirements on a timely basis. We will also become subject to other reporting and corporate governance requirements, including the requirements of the             , and certain provisions of the Sarbanes-Oxley Act (“SOX”) and the regulations promulgated thereunder, which will impose significant compliance obligations upon us. As a public company, we will, among other things:

•prepare and distribute periodic public reports and other stockholder communications, including proxy statements, in compliance with our obligations under the federal securities laws and applicable                rules;

•hold annual shareholder meetings;

•create or expand the roles and duties of our board of directors and committees of the board;

•institute more comprehensive financial reporting and disclosure compliance functions;

•supplement our internal accounting, internal controls, auditing and reporting function, including hiring additional staff with expertise in accounting and financial reporting for a public company, in compliance with Section 404 of SOX;

•enhance and formalize closing procedures at the end of our accounting periods;

•enhance our internal audit and tax functions;

•enhance our investor relations function;

•establish new internal policies, including those relating to disclosure controls and procedures; and

•involve and retain to a greater degree outside counsel and accountants in the activities listed above.

These changes will require a significant commitment of additional resources and many of our competitors already comply with these obligations. Although we had previously been a public company until 2008, we became privately owned following our acquisition by Finmeccanica – Societá per azioni (now Leonardo S.p.A.). Given the significant passage of time that followed, we no longer benefit from the

49

prior infrastructure we had in place as a publicly held company. In connection with preparing for this offering and operating as a stand-alone public company following the closing of this offering, we expect to incur one-time and recurring expenses. We estimate that the aggregate amount of the one-time expenses described above will be between approximately $11 million and $14 million, of which between $7 million and $9 million is anticipated to be incurred in the year ended December 31, 2020 and approximately $2 million to $7 million is expected to be incurred in the year ended December 31, 2021. This does not include bank fees related to the securing of third party financing or amounts paid by US Holding out of the proceeds of this offering including underwriting discounts and commissions. In addition, for so long as our parent company, Leonardo S.p.A., consolidates our financial position and results of operations in its consolidated financial statements, we expect to engage the same auditing firm to act as our independent registered public accounting firm. Leonardo S.p.A. will be required to change its auditing firm in 2021 in light of European mandatory audit firm rotation rules, which we expect will require us to change our audit firm. A new auditing firm may apply certain auditing standards or accounting practices differently, which, among other factors, may result in additional costs, delays or other issues in preparing our audited financial statements.

We may not be successful in implementing all of the going-public requirements described above and the significant commitment of resources required for implementing them could adversely affect our business, financial condition and results of operations. In addition, if we fail to implement the requirements with respect to our internal accounting and audit functions, our ability to report our results of operations on a timely and accurate basis could be impaired and we could suffer adverse regulatory consequences or violate                 listing standards. There could also be a negative reaction in the financial markets due to a loss of investor confidence in us and the reliability of our financial statements.

The changes necessitated by becoming a public company require a significant commitment of resources and management oversight that has increased and may continue to increase our costs and might place a strain on our systems and resources. As a result, our management’s attention might be diverted from other business concerns. Some members of our management team have limited experience managing a publicly traded company, interacting with public company investors and complying with the increasingly complex laws pertaining to public companies. Our management team may not successfully or efficiently manage our transition to being a public company that is subject to significant regulatory oversight and reporting obligations under the federal securities laws and the continuous scrutiny of securities analysts and investors.

If we are unable to offset these costs through other savings then it could have a material adverse impact on our business, financial condition and results of operations.

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

We derive a portion of our revenues from programs with the U.S. government that are subject to security restrictions that preclude the dissemination of information that is classified for national security purposes. We are limited in our ability to provide details about these classified programs, their risks or any disputes or claims relating to such programs, and may not disclose such information pursuant to SEC rules permitting confidential treatment of certain information. As a result, investors and others might have less insight into our classified programs than our other businesses and, therefore, less ability to fully evaluate the risks related to our classified business.

Future sales of shares by existing stockholders could cause our stock price to decline.

Sales of substantial amounts of our common stock in the public market following this offering, or the perception that these sales could occur, could cause the market price of our common stock to decline. These sales, or the possibility that these sales may occur, also might make it more difficult for us to sell equity securities in the future at a time and at a price that we deem appropriate. Immediately after this

50

offering, Leonardo S.p.A. through US Holding will own       % of our outstanding common stock (or      % if the underwriters exercise their option to purchase additional shares in full).

As of             , 2021, we have           outstanding shares of common stock. All of the shares sold pursuant to this offering will be immediately tradable without restriction under the Securities Act of 1933, as amended (the “Securities Act,”), except for any shares held by “affiliates,” as that term is defined in Rule 144 under the Securities Act, or “Rule 144.”

The remaining shares of common stock outstanding as of          , 2021 will be restricted securities within the meaning of Rule 144, but will be eligible for resale subject, in certain cases, to applicable volume, manner of sale, holding period and other limitations of Rule 144 subject to the terms of the lock-up agreements described below.

Upon the closing of this offering, we intend to file one or more registration statements on Form S‑8 under the Securities Act to register the shares of common stock to be issued under our equity compensation plans and, as a result, all shares of common stock acquired upon exercise of stock options granted under our plans will also be freely tradable under the Securities Act, subject to the terms of the lock-up agreements, unless purchased by our affiliates. As of            , 2021,             shares of our common stock are reserved for future issuances under the equity incentive plan adopted in connection with this offering.

In connection with this offering, we, US Holding and all of our directors and executive officers will enter into lock-up agreements under which, subject to certain exceptions, we and they will agree not to dispose of or hedge any of our common stock or securities convertible into or exchangeable for shares of our common stock for a period of 180 days after the date of this prospectus, except with the prior written consent of Goldman Sachs & Co. LLC. Following the expiration of this 180-day lock-up period, approximately          shares of our common stock will be eligible for future sale, subject to the applicable volume, manner of sale, holding period and other limitations of Rule 144. As resale restrictions end, the market price of our common stock could decline if US Holding sells its shares or is perceived by the market as intending to sell them. Goldman Sachs & Co. LLC may, in its sole discretion and at any time, release all or any portion of the securities subject to lock-up agreements entered into in connection with this offering. Furthermore, subject to the expiration or waiver of the lock up agreements, US Holding will have the right to require us to register shares of common stock for resale in some circumstances pursuant to the registration rights agreement we will enter into with US Holding. For a description of the registration rights agreement, see “Certain Relationships and Related-Party Transactions—Relationship with Leonardo S.p.A. Following this Offering—Registration Rights Agreement.”

In the future, we may issue additional shares of common stock or other equity or debt securities convertible into or exercisable or exchangeable for shares of our common stock in connection with a financing, strategic investment, litigation settlement or employee arrangement or otherwise. Any of these issuances could result in substantial dilution to our existing stockholders and could cause the trading price of our common stock to decline.

Our common stock has no prior public market, and the market price of our common stock may be volatile and could decline after this offering.

Prior to this offering, there has been no public market for our common stock, and an active market for our common stock may not develop or be sustained after this offering. We have been approved to list our common stock on the              . We and US Holding negotiated the initial public offering price per share with the representatives of the underwriters and, therefore, that price may not be indicative of the market price of our common stock after this offering. We cannot assure you that an active public market for our common stock will develop after this offering or, if one does develop, that it will be sustained. In the absence of an active public trading market, you may not be able to sell your shares. An inactive market may also impair our ability to raise capital to continue to fund operations by selling shares and may impair our ability to make strategic investments by using our shares as consideration. In addition, the market

51

price of our common stock may fluctuate significantly. Among the factors that could affect our stock price are:

•industry or general market conditions;

•domestic and international economic factors unrelated to our performance;

•announcements as to a Congressional or Presidential initiative with respect to changes in spending priorities and defense spending levels, sequestration, the appropriations process, use of continuing resolutions (with restrictions, e.g., on starting new programs) and the permissible level of federal debt;

•changes in our customers’ preferences;

•new regulatory pronouncements and changes in regulatory guidelines;

•lawsuits, enforcement actions and other claims by third parties or governmental authorities;

•adverse publicity related to us or another industry participant;

•actual or anticipated fluctuations in our operating results;

•changes in securities analysts’ estimates of our financial performance or lack of research coverage and reports by industry analysts;

•action by institutional stockholders or other large stockholders, including future sales of our common stock;

•failure to meet any guidance given by us or any change in any guidance given by us, or changes by us in our guidance practices;

•announcements by us of significant impairment charges;

•speculation in the press or investment community;

•investor perception of us and our industry;

•changes in market valuations or earnings of similar companies;

•announcements by us or our competitors of significant contracts, acquisitions, dispositions or strategic partnerships;

•war, terrorist acts and a pandemic or epidemic disease;

•any future sales of our common stock or other securities;

•additions or departures of key personnel; and

•misconduct or other improper actions of our employees.

In particular, we cannot assure you that you will be able to resell your shares at or above the initial public offering price. Stock markets have experienced extreme volatility in recent years that has been unrelated to the operating performance of particular companies. These broad market fluctuations may adversely affect the trading price of our common stock. In the past, following periods of volatility in the market price of a company’s securities, class action litigation has often been instituted against the affected company. Any litigation of this type brought against us could result in substantial costs and a diversion of our management’s attention and resources, which could materially and adversely affect our business, results of operations or financial condition.

52

If securities or industry analysts do not publish research or publish misleading or unfavorable research about our business, our stock price and trading volume could decline.

The trading market for our common stock will depend in part on the research and reports that securities or industry analysts publish about us or our business. We do not currently have, and may never obtain, research coverage for our common stock. If there is no research coverage of our common stock, the trading price for our common stock may be negatively impacted. In the event we obtain research coverage for our common stock, if one or more of the analysts downgrades our stock or publishes misleading or unfavorable research about our business, our stock price would likely decline. If one or more of the analysts ceases coverage of our common stock or fails to publish reports on us regularly, demand for our common stock could decrease, which could cause our common stock price or trading volume to decline.

Future offerings of debt or certain equity securities which would rank senior to our common stock may adversely affect the market price of our common stock.

If, in the future, we decide to issue debt or equity securities that rank senior to our common stock, it is likely that such securities will be governed by an indenture or other instrument containing covenants restricting our operating flexibility. Our amended and restated certificate of incorporation will also authorize the issuance of “blank check” preferred stock that could be issued by our board. Additionally, any convertible or exchangeable securities that we issue in the future may have rights, preferences and privileges more favorable than those of our common stock and may result in dilution to owners of our common stock. We and, indirectly, our stockholders, will bear the cost of issuing and servicing such securities. Because our decision to issue debt or equity securities in any future offering will depend on market conditions and other factors beyond our control, we cannot predict or estimate the amount, timing or nature of our future offerings. Thus, holders of our common stock will bear the risk of our future offerings reducing the market price of our common stock and diluting the value of their stock holdings in us.

We do not expect to declare any dividends in the near term.

We do not anticipate declaring any cash dividends to holders of our common stock in the near term. Consequently, investors may need to rely on sales of their common stock after price appreciation, which may never occur, as the only way to realize any future gains on their investment. Investors seeking cash dividends should not purchase our common stock. In addition, the proxy holders may only vote to declare or suspend dividends after prior consultation with US Holding.

Anti-takeover provisions in our amended and restated certificate of incorporation and amended and restated by-laws and Delaware law could discourage, delay or prevent a change of control of our company and may affect the trading price of our common stock.

Our amended and restated certificate of incorporation and our amended and restated by-laws include a number of provisions that may discourage, delay or prevent a change in our management or control over us that stockholders may consider favorable. For example, prior to the closing of this offering, our amended and restated certificate of incorporation and amended and restated by-laws will collectively:

•authorize the issuance of shares of our common stock to create voting impediments or to frustrate persons otherwise seeking to effect a takeover or gain control;

•authorize the issuance of “blank check” preferred stock that could be issued by our board to thwart a takeover attempt;

•provide that vacancies on our board, including vacancies resulting from an enlargement of our board, may be filled only by a majority vote of directors then in office following termination of the proxy agreement;

53

•prohibit stockholders from calling special meetings of stockholders following termination of the proxy agreement;

•prohibit stockholder action by written consent, thereby requiring all actions to be taken at a meeting of the stockholders, following termination of the proxy agreement;

•establish advance notice requirements for nominations of candidates for election as directors or to bring other business before an annual meeting of our stockholders; and

•require the approval of holders of at least 66 2⁄3% of the outstanding shares of our common stock to amend our amended and restated by-laws and certain provisions of our amended and restated certificate of incorporation following termination of the proxy agreement.

These provisions may prevent our stockholders from receiving the benefit from any premium to the market price of our common stock offered by a bidder in a takeover context. In addition, the requirement in our proxy agreement for approval by the proxy holders and our majority stockholder of mergers and consolidations also may discourage change of control transactions. Even in the absence of a takeover attempt, the existence of these provisions may adversely affect the prevailing market price of our common stock if the provisions are viewed as discouraging takeover attempts in the future.

Our amended and restated certificate of incorporation and amended and restated by-laws may also make it difficult for stockholders to replace or remove our management. Furthermore, the existence of the foregoing provisions, as well as the significant amount of common stock that US Holding will beneficially own following this offering, could limit the price that investors might be willing to pay in the future for shares of our common stock. These provisions may facilitate management entrenchment that may delay, deter, render more difficult or prevent a change in our control, which may not be in the best interests of our stockholders.

Our amended and restated certificate of incorporation will include provisions limiting the personal liability of our directors for breaches of fiduciary duty under the Delaware General Corporation Law.

Our amended and restated certificate of incorporation will contain provisions permitted under the General Corporation Law of the State of Delaware, or the “DGCL,” relating to the liability of directors. These provisions will eliminate a director’s personal liability to the fullest extent permitted by the DGCL for monetary damages resulting from a breach of fiduciary duty, except in circumstances involving:

•any breach of the director’s duty of loyalty;

•acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of the law;

•under Section 174 of the DGCL (unlawful dividends); or

•any transaction from which the director derives an improper personal benefit.

The principal effect of the limitation on liability provision is that a stockholder will be unable to prosecute an action for monetary damages against a director unless the stockholder can demonstrate a basis for liability for which indemnification is not available under the DGCL. These provisions, however, should not limit or eliminate our rights or any stockholder’s rights to seek non-monetary relief, such as an injunction or rescission, in the event of a breach of a director’s fiduciary duty. These provisions will not alter a director’s liability under federal securities laws. The inclusion of this provision in our amended and restated certificate of incorporation may discourage or deter stockholders or management from bringing a lawsuit against directors for a breach of their fiduciary duties, even though such an action, if successful, might otherwise have benefited us and our stockholders.

Our amended and restated certificate of incorporation will designate the Court of Chancery of the State of Delaware as the sole and exclusive forum for certain litigation that may be initiated by our stockholders, and federal district courts as the exclusive forum for Securities Act claims, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers or stockholders.

Our amended and restated certificate of incorporation will provide that, unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware will, to the fullest extent permitted by law, be the sole and exclusive forum for (i) any derivative action or proceeding brought on our behalf, (ii) any action asserting a claim of breach of a fiduciary duty owed to us or our stockholders by any of our directors, officers, other employees, agents or stockholders, (iii) any action asserting a claim arising out of or under the DGCL, or as to which the DGCL confers jurisdiction on the Court of Chancery of the State of Delaware (including, without limitation, any action asserting a claim arising out of or pursuant to our amended and restated certificate of incorporation or our amended and restated by-laws) and (iv) any action asserting a claim that is governed by the internal affairs doctrine. The foregoing provision does not apply to claims arising under the Securities Act or the Securities Exchange Act or other federal securities laws for which there is exclusive federal or concurrent federal and state jurisdiction. Our stockholders cannot waive compliance with the federal securities laws and the rules and regulations thereunder.

Furthermore, unless we select or consent to the selection of an alternative forum, our amended and restated certificate of incorporation will provide that the federal district courts of the United States of America shall be the exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act.

By becoming a stockholder in our company, you will be deemed to have notice of and have consented to the provisions of our amended and restated certificate of incorporation related to choice of forum. The choice of forum provision in our amended and restated certificate of incorporation may limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or any of our directors, officers, other employees, agents or stockholders, which may discourage lawsuits with respect to such claims. Alternatively, if a court were to find the choice of forum provision contained in our amended and restated certificate of incorporation to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving such action in other jurisdictions, which could materially and adversely affect our business, results of operations or financial condition.

DIVIDEND POLICY

We do not currently anticipate declaring or paying regular cash dividends on our common stock in the near term. We expect that we will retain all of our future earnings for use in the operation and expansion of our business. Subject to the foregoing, the payment of cash dividends in the future, if any, will be at the discretion of our board and will depend upon such factors as our financial condition, earnings, liquidity and capital requirements, level of indebtedness, general business conditions, applicable Delaware law, which provides that dividends are only payable out of surplus or current net profits, and any other factors that our board deems relevant in making such a determination. In addition, the terms of the agreements governing the debt we have incurred or may incur may limit or prohibit the payment of dividends. Further, the proxy holders, in their capacity as directors, may vote to declare or suspend dividends only after prior consultation with US Holding.Therefore, there can be no assurance that we will pay any dividends to holders of our common stock, or as to the amount of any such dividends. See “Risk Factors—Risks Relating to Our Common Stock and This Offering—We do not expect to declare any dividends in the near term.”

58

RECAPITALIZATION

We have historically operated with a capital structure that reflected our status as a wholly owned indirect subsidiary of Leonardo S.p.A. Our debt with related parties consists of three term loans and a working capital credit facility with US Holding, as described in “Certain Relationships and Related Party Transactions—Transactions with Leonardo S.p.A. Affiliates—Financing Arrangements.” To prepare for this offering and operation as a stand-alone public company, we will undertake various recapitalization initiatives to align our capital structure more closely with other U.S. public companies (the “Recapitalization”). In undertaking the Recapitalization, we are focused on several goals:

•Maintaining and strengthening our credit ratings; and

•Increasing liquidity at the DRS level.

Prior to the consummation of this offering, we expect to implement the following financing arrangements as part of our efforts to align our capital structure more closely with other U.S. public companies and achieve the goals described above:

•the repayment of          million of related-party borrowings; and

•the expected issuance of          million of third-party debt.

For more information, see the sections “Capitalization,” “Unaudited Pro Forma Consolidated Financial Information” and “Certain Relationships and Related Party Transactions—Transactions with Leonardo S.p.A. Affiliates—Financing Arrangements” in this prospectus.

This discussion and other parts of this prospectus include forward-looking statements such as those relating to our plans, objectives, expectations and beliefs, which involve risks, uncertainties and assumptions.

Business Overview and Considerations

General

We are a leading provider of defense products and technologies that are used across land, air, sea, space and cyber domains. Our diverse array of defense systems and solutions is offered to all branches of the U.S. military, major aerospace and defense prime contractors, government intelligence agencies and international military customers for deployment on a wide range of military platforms. We focus our capabilities in areas of critical importance to the U.S. military within three segments, Advanced Sensor Technologies, Network Computing & Communications and Integrated Mission Systems. Our revenue, earnings and cash flows are generated by a combination of developing, manufacturing and servicing advanced technology solutions that are designed to address mission critical challenges for the defense industry.

Our overall strategy is to be a balanced and diversified company, less vulnerable to any one budgetary platform or service decision with a specific focus on establishing strong technical and market positions in areas of priority for the DoD. The DoD is our largest customer and, for the year ended December 31, 2019, accounted for approximately 89% of our business as an end-user, with revenues principally derived directly or indirectly from contracts with the U.S. Army and U.S. Navy, which represented 40% and 36%, respectively, of our total revenues for the year ended December 31, 2019. We use our technical capabilities, customer relationships and product quality to drive our financial performance, evidenced by a 16% CAGR in revenue from the year ended December 31, 2016 through the year ended December 31, 2019, which drove our annual revenue to $2.7 billion for the year ended December 31, 2019. During the same period, net earnings (loss) improved by $237 million to $75 million, our operating earnings grew $160 million to $163 million, and our Adjusted EBITDA grew $81 million to $234 million (CAGR of 15%) . Adjusted EBITDA is a non-GAAP measure, see “—Key Financial and Operating Measures—Non-GAAP Financial Measures” below for a reconciliation of Adjusted EBITDA to net earnings.

Our operations and reporting are structured into the following three technology driven segments based on the capabilities and solutions offered to our customers:

Advanced Sensor Technologies (“AST”): Our Advanced Sensor Technologies segment provides world-class electro-optical sensor technologies, laser systems, EW systems and intelligence and surveillance solutions to U.S. military and intelligence community customers. We are a leading provider of ground vehicle targeting and surveillance sensors, including electro-optical and advanced detection systems. We are also a leading provider of soldier sensor systems in high priority modernization areas such as infrared imaging and precision targeting systems. Our infrared focal plane array foundry is recognized as a leading provider of high performance and small sized cryogenically cooled and uncooled detector arrays. We are also a leading and world-recognized provider of aircraft training instrumentation equipment and high-performance radio frequency receivers and transceivers for U.S. and international customers. Our quantum cascade laser

68

technology has promising military and commercial medical applications. Collectively, these sensor technologies provide our warfighters with a distinct battlefield advantage.

Network Computing & Communications (“NC&C”): Our Network Computing & Communications segment provides advanced defense electronics solutions across warfare domains. Our technologies and products are used on legacy and new military platforms, end-to-end network communication systems, satellite services and cyber solutions. We are a leading provider of ruggedized computing equipment, having provided advanced tactical computing units for ground combat vehicles and command post operations for more than two decades. During this period we have delivered more than 125,000 units. For the U.S. Navy and its allies, we provide naval computing infrastructure, network and data distribution, radar and rugged naval control systems, which are present on naval surface and subsurface combatant vessels. Across the full spectrum of our network computing capabilities, we have leadership positions at both the product and sub-systems levels. Our global communications network is a worldwide network of terrestrial and satellite bandwidth that ensures our customers’ data is secure and reliable. As a result of this capability, we are positioned as one of the leading providers of secured satellite communications to the U.S. military.

Integrated Mission Systems (“IMS”): Our Integrated Mission Systems segment provides critical force protection, vehicle integration, transportation and logistics and electrical conversion and ship propulsion systems to the U.S. military. Our force protection systems protect service members and military assets from evolving threats and include solutions for counter-unmanned aerial systems, short-range air defense systems and active protection systems on ground vehicles. In 2018, we were awarded the Expedited Active Protection System program by bringing the TROPHY™ Active Protection System (“APS”) to the U.S. market, making us the leading U.S. provider of active protection systems for the U.S. Army. We were also awarded the Initial Maneuver Short-Range Air Defense (“IM-SHORAD”) Mission Equipment Package Program for the U.S. Army that year, culminating an 18-month cycle from development to customer delivery. We have military transportation and logistics offerings and ground vehicle integration capabilities to support U.S. forces in a wide range of operational environments. We provide power conversion and propulsion systems for the U.S. Navy’s top priority shipbuilding programs, building on our legacy of providing power components and systems for nearly all naval combat vessels for three decades, positioning us to continue as a leading provider of electrical ship propulsion systems and components for the U.S. Navy.

Focus on Customer and Execution

DRS and its employees focus on our end-customers – the men and women of the armed forces in the U.S. and its allies. We seek to provide high-quality equipment and services to support their mission success. We strive for excellence in everything we do, in every job in our Company, in order to satisfy our customers’ needs embedded in our contractual commitments. We seek to ensure that we learn from every lesson experienced in our Company and insist that these lessons affect all elements of our businesses. This approach permeates through the Company with a focus on continuous improvement at every level.

Part of this learning has resulted in institutionalizing our continuous improvement process through our APEX program. The APEX program’s goal is to strive for continuous improvement through unification of our business practices, tools and metrics, ongoing employee training and innovation. We believe that excellence is not a destination, but by constantly challenging ourselves to be better, we will improve, and ultimately approach excellence. We challenge ourselves to exceed our customers’ expectations and we partner with them to work to ensure that our execution meets their needs.

Continuous improvement, through the APEX program also allows us to improve our efficiency, which contributes to increased margins, helps us to remain competitive and allows us to make strategic investments, all while maintaining our focus on customer satisfaction. In these elements, our goals are aligned with those of our customers. We are humbled by the dedication and sacrifice that our ultimate customers have made to serve and we work to perform for them with excellence in everything we do.

Impacts of COVID-19 On Our Business

Since the emergence of the novel coronavirus known as COVID-19, DRS has responded to ensure business continuity and we believe our innovative culture has enabled us to perform in difficult circumstances. DRS has been deemed an essential business due to our mission to provide products and services to the military. Our COVID-19 plan focuses on three factors: keeping our employees and their families safe; mitigating risk associated with interruption of suppliers’ materials; and maintaining our commitment to our customers. This response included maximizing work from home, physical separation of the remaining employees into small zones, frequent CEO level communications to employees, intra-shift sanitization of facilities, Company-paid healthcare leave and quarantining of zones where a concern of exposure arises. We remain committed to the safety and health of our employees while ensuring continuity of our operations.

The proactive management to mitigate the impact of COVID-19 has enabled our business to remain operational. However, we incurred approximately $10 million of expenditures from March 1, 2020 through November 30, 2020 to ensure a safe work environment for our employees. These costs include paid leave, personal protective equipment and other cleaning measures, facility filtration systems and social and physical distancing efforts, including the use of zones and subzones for manufacturing facilities. Costs to combat the COVID-19 pandemic have been excluded from our Adjusted EBITDA results. See “—Key Financial and Operating Measures—Non-GAAP Financial Measures.”

Despite the increase in expenditures, DRS did offset a portion of the cash impacts of our COVID-19 response through utilization of Section 3610 of the CARES Act, allowing for a deferral of social security payroll tax payments to 2021 and 2022 and pension related contributions to 2021. This largely offset increases in our working capital levels due to COVID-19 impacts on certain programs driven by delays stemming from restrictions in customer test facility access and supplier delays. Additionally, we benefited from the DoD decision to increase the rate for certain progress payments from 80% to 90% for costs incurred and work performed on relevant contracts as a response to COVID-19. We believe these actions should continue to mitigate some COVID-19 related negative impacts to our operating cash flows. To date, DRS has not issued any contractual request for equitable adjustments attributed to COVID-19 related expenditures discussed above and pursuant to the Section 3610 of the CARES Act.

Business Environment

Revenues derived directly, as a prime contractor, or indirectly, as a subcontractor, from contracts with the U.S. government represented 89% and 86% of our total revenues for the years ended December 31, 2019 and 2018, respectively. Our U.S. government sales are highly concentrated within our DoD customers, which made up the overwhelming majority of our U.S. government revenue for the year ended December 31, 2019 and are principally derived directly or indirectly from contracts with the U.S. Army and U.S. Navy, which represented 40% and 36%, respectively, of our total revenues for the year ended December 31, 2019 . Therefore, our revenue is highly correlated to changes in U.S. government spending levels, especially within the DoD.

Fiscal year 2020 began with the U.S. government responding to the on-going COVID-19 global pandemic. While the DoD budget was expected to slow during 2020 from a CAGR of 5.8% from 2016 to 2019, COVID-19 placed additional pressure on the budget. To address the COVID-19 pandemic, the federal government passed four different coronavirus stimulus bills in 2020 totaling nearly $3 trillion that were designed to help stimulate the economy and provide relief to the American people. As the DoD is the largest part of the federal discretionary budget, the costs of these relief bills have begun to place some pressure on the DoD budget. While we believe that the results of the 2020 federal election will not have a significant impact on defense spending in the near-term, President‑Elect Biden has not had an opportunity to lay out his specific plan.

As soon as the COVID-19 global pandemic began, we were designated as an essential business in each of the jurisdictions in which we operate and we worked to ensure continuity of our operations to

70

meet our contractual obligations. Throughout 2020, the DoD has provided funding and special provisions to ensure adequate funding for these continued operations, and we remained at an approximately 98% staffing level throughout the year. Our people have risen to the challenge and performed with distinction during this time period, and as a result our performance has been strong.

Due to the high correlation of our revenue to changes in the DoD spending levels, the passage of applicable appropriations and funding bills, and the authorization of the President’s budget request, contribute to our funding expectations. The 2021 fiscal year defense bill, the 2021 National Defense Authorization Act (“NDAA”) remained under consideration by the Senate and House of Representatives as of November 30, 2020, and is projected to fund a total of $740.5 billion if approved during final passage. Similarly, the companion 2021 Defense Appropriations Bill is working its way through the legislative process and would provide funding at a similar level. Both of these pieces of legislation are likely to be considered by the end of the 2020 calendar year, but may not be considered until 2021, based on political developments, and, if approved, would provide high levels of defense spending by historical standards, demonstrating that the U.S. defense market remains strong. At slightly under 40% of total global defense spending, the U.S. defense budget remains the largest in the world.

We believe that the budget environment provides appropriate funding for the technologies, products, subsystems, systems and services we provide. Future DoD budgets and spending levels are determined by a number of factors beyond our control, including changes to U.S. government procurement policies, current and future domestic and international budget conditions, presidential administration priorities and changing national security and defense requirements.

Key Financial and Operating Measures

Overview

We measure our business using both key financial and operating data including key performance indicators (“KPIs”) and non-GAAP financial measures and use the following metrics to manage our business, monitor results of operations and ensure proper allocation of capital: (i) Revenue, (ii) Bookings, (iii) Backlog, (iv) Adjusted EBITDA, (v) Adjusted EBITDA Margin, (vi) Adjusted Earnings Per Share (“EPS”), (vii) Leverage Ratio, and (viii) Free Cash Flow. We believe that these financial performance metrics represent the primary drivers of value enhancement, balancing both short and long-term indicators of increased shareholder value. These are the metrics we use to measure our results and evaluate our business and related contract performance. See “—Results from Operations” for further detail.

________________

(1)Note on non-GAAP financial measures: Throughout the discussion of our results of operations we use non-GAAP financial measures including Adjusted EBITDA, Adjusted EBITDA Margin, Adjusted EPS, Leverage Ratio and Free Cash Flow, as measures of our overall performance. Definitions and reconciliations of these measures

71

to the most directly comparable financial measure calculated and presented in accordance with U.S. GAAP are included below.

(2)Gives effect to a                -for-               stock split on our common stock to be effected prior to the completion of this offering.

Bookings - We define bookings as the total value of contract awards received from the U.S. government for which it has appropriated funds and legally obligated such funds to the Company through a contract or purchase order, plus the value of contract awards and orders received from customers other than the U.S. government.

Backlog - We define Backlog to include the following components:

(1)Funded - Funded backlog represents the revenue value of orders for services under existing contracts for which funding is appropriated or otherwise authorized less revenue previously recognized on these contracts.

(2)Unfunded - Unfunded backlog represents the revenue value of orders for services under existing contracts for which DRS has not been authorized with contract funding, less revenue previously recognized on these contracts.

Estimated Potential Remaining Contract Value - In addition to backlog, we also evaluate estimated potential remaining contract value, which represents unexercised options associated with existing firm contracts and other contract commitments where items are visible in the DoD budget estimates and are void of competitive risks, including options on IDIQ type contracts and follow-on orders with existing customers.

Total Estimated Contract Value - Estimated potential remaining contract value together with backlog represents total estimated contract value.

The following table summarizes the value of our backlog, estimated potential remaining contract value and total estimated contract value at the respective dates presented:

Backlog:

	December 31,
(Dollars in millions)	2019		2018

(1)See “Risk Factors—Risks Relating to Our Business—We may not realize the full value of our total estimated contract value or bookings, including as a result of reduction of funding or cancellation of our U.S. government contracts, which could have a material adverse impact on our business, financial condition and results of operations.”

Non-GAAP Financial Measures

We believe the non-GAAP financial measures presented in this prospectus will help investors understand our financial condition and operating results and assess our future prospects. We believe these non-GAAP financial measures, each of which is discussed in greater detail below, are important supplemental measures because they exclude unusual or non-recurring items as well as non-cash items that are unrelated to or may not be indicative of our ongoing operating results. Further, when read in conjunction with our U.S. GAAP results, these non-GAAP financial measures provide a baseline for

72

analyzing trends in our underlying businesses and can be used by management as a tool to help make financial, operational and planning decisions. Finally, these measures are often used by analysts and other interested parties to evaluate companies in our industry by providing more comparable measures that are less affected by factors such as capital structure.

We recognize that these non-GAAP financial measures have limitations, including that they may be calculated differently by other companies or may be used under different circumstances or for different purposes, thereby affecting their comparability from company to company. In order to compensate for these and the other limitations discussed below, management does not consider these measures in isolation from or as alternatives to the comparable financial measures determined in accordance with U.S. GAAP. Readers should review the reconciliations below and should not rely on any single financial measure to evaluate our business.

We define these non-GAAP financial measures as:

Adjusted EBITDA and Adjusted EBITDA Margin - We define Adjusted EBITDA as our net earnings before income taxes, amortization of acquired intangible assets, depreciation, restructuring costs, interest, transaction costs related to this offering, acquisition and divestiture related expenses, foreign exchange, COVID-19 response costs, non-service pension expenditures and other one-time non-operational events. Adjusted EBITDA Margin is calculated by dividing Adjusted EBITDA by revenue. Adjusted EBITDA and Adjusted EBITDA Margin are not measures calculated in accordance with U.S. GAAP, and they should not be considered an alternative to any financial measures that were calculated under U.S. GAAP. Adjusted EBITDA and Adjusted EBITDA Margin are used to facilitate a comparison of the ordinary, ongoing and customary course of our operations on a consistent basis from period to period and provide an additional understanding of factors and trends affecting our business. Adjusted EBITDA and Adjusted EBITDA Margin are driven by changes in volume, performance, contract mix and general and administrative expenses and investment levels. Performance, as used in this definition, refers to changes in profitability and is primarily based on adjustments to estimates at completion on individual contracts. These adjustments result from increases or decreases to the estimated value of the contract, the estimated costs to complete the contract, or both. These measures therefore assist management and our board and may be useful to investors in comparing our operating performance consistently over time as they remove the impact of our capital structure, asset base and items outside the control of the management team and expenses that do not relate to our core operations. Adjusted EBITDA and Adjusted EBITDA Margin may not be comparable to similarly titled non-GAAP measures used by other companies as other companies may have calculated the measures differently. The reconciliation of Adjusted EBITDA to net earnings (loss) is provided below:

Adjusted EBITDA	$	234	$	187

Adjusted EPS – We calculate Adjusted EPS by excluding transaction costs related to this offering, acquisition and divestiture related expenses and COVID-19 response costs from our net earnings (loss) to arrive at Adjusted EPS. We believe that Adjusted EPS allows investors to effectively compare our core performance from period to period by excluding items that are not indicative of, or are unrelated to, results from our ongoing business operations such as our capital structure, significant non-cash expenses, the impacts of financing decisions on earnings, and items incurred outside the ordinary, ongoing and customary course of our business. Adjusted EPS has limitations as an analytical tool and does not represent, and should not be considered an alternative to basic or diluted EPS as determined in accordance with U.S. GAAP. The reconciliation of Adjusted EPS to U.S. GAAP EPS is shown below:

Leverage Ratio - We define our leverage ratio as total net debt divided by Adjusted EBITDA. Net debt includes debt related to financing lease obligations net of balance sheet cash and cash equivalents and related party note receivables.

74

The table below provides the calculation of the Leverage Ratio as of December 31, 2019 and 2018.

Total net debt	$	527		$	560
Adjusted EBITDA	234			187
Leverage Ratio	2.3		x	3.0		x

Free Cash Flow – We define free cash flow as the sum of the cash flows provided by operating activities and the cash flows provided by (used in) investment activities pertaining to capital expenditures and proceeds generated from the sale of assets.

We believe that free cash flow provides management and investors with an important measure of our ability to generate cash on a normalized basis. Free cash flow also provides insight into our flexibility to allocate capital and pursue opportunities that may enhance shareholder value. We believe that while expenditures and dispositions of property plant and equipment will fluctuate period to period, we seek to ensure that we have adequate capital on hand to maintain ongoing operations and enable growth of the business. Additionally, free cash flow is of limited usefulness, in that it does not represent residual cash flows available for discretionary expenditures, due to the fact the measures do not deduct the payments required for debt service and other contractual obligations or payments. The reconciliation between free cash flow and net cash provided by operating activities (the most comparable U.S. GAAP measure) is shown below:

Factors Impacting Our Performance

U.S. Government Spending and Federal Budget Uncertainty

Changes in the volume and relative mix of U.S. government spending as well as areas of spending growth could impact our business and results of operations. In particular, our results can be affected by shifts in priorities on homeland security, intelligence, defense-related programs, infrastructure and urbanization and continued increased spending on technology and innovation, including cybersecurity, artificial intelligence, connected communities and physical infrastructure. Cost-cutting and efficiency initiatives, current and future budget restrictions, spending cuts and other efforts to reduce government spending and shifts in overall priorities (for example, in response to the COVID-19 pandemic) could cause our government customers to reduce or delay funding or invest appropriated funds on a less consistent basis or not at all, and demand for our solutions or services could diminish. Furthermore, any disruption in the functioning of government agencies, including as a result of government closures and shutdowns, could have a negative impact on our operations and cause us to lose revenue or incur additional costs

75

due to, among other things, our inability to maintain access and schedules for government testing or deploy our staff to customer locations or facilities as a result of such disruptions.

There is also uncertainty around the timing, extent, nature and effect of Congressional and other U.S. government actions to address budgetary constraints, caps on the discretionary budget for defense and non-defense departments and agencies, and the ability of Congress to determine how to allocate the available budget authority and pass appropriations bills to fund both U.S. government departments and agencies that are, and those that are not, subject to the caps. Additionally, budget deficits and the growing U.S. national debt, including as a result of legislative actions in response to the COVID-19 pandemic, may increase pressure on the U.S. government to reduce federal spending across all federal agencies, with uncertainty about the size and timing of those reductions. Furthermore, delays in the completion of future U.S. government budgets could in the future delay procurement of the federal government services we provide. A reduction in the amount of, or reductions, delays, or cancellations of funding for, services that we are contracted to provide to the U.S. government as a result of any of these impacts or related initiatives, legislation or otherwise could have a material adverse effect on our business and results of operations. See “Risk Factors—Risks Related to Our Business—Significant delays or reductions in appropriations for our programs and changes in U.S. government priorities and spending levels more broadly may negatively impact our business and could have a material adverse impact on our business, financial condition and results of operations” and “Risk Factors—Risks Related to Our Business—The COVID-19 pandemic and related impacts have had and are likely to continue to have an adverse impact on our business, financial condition and results of operations.”

Operational Performance on Contracts

Revenue, earnings (margin) and the timing of our cash flows depend on our ability to perform on our contracts. When agreeing to contractual terms, our management team makes assumptions and projections about future conditions and events. The accounting for our contracts and programs requires assumptions and estimates about these conditions and events. These projections and estimates assess:

•the productivity and availability of labor;

•the allocation of indirect costs to labor and material costs incurred

•the complexity of the work to be performed;

•the cost and availability of materials and components; and

•schedule requirements.

If there is a significant change in one or more of these circumstances, estimates or assumptions, or if the risks under our contracts are not managed adequately, the profitability of contracts could be adversely affected. This could affect earnings and margin materially.

In particular, profitability can fluctuate predicated on the type of contract awarded. Typically fixed-price development programs on complex systems represent a higher risk profile to complete on-time and on-budget. To the extent our fixed-price development efforts create a larger portion of our revenue output, this may result in reduced operating margins given the higher risk profile. The following represents the impact that changing certain of our estimates, particularly those regarding our fixed-price development programs, would have on our revenues:

76

Impact of Change in Estimates on our Revenue Results

	Year Ended December 31,
(Dollars in millions)	2019			2018
Revenue	$	(55)		$	(26)
Total % of Revenue	2		%	1		%

Additionally, the timing of our cash flows is impacted by the timing of achievement of billable milestones on contracts. Historically, this has resulted and could continue to result in fluctuations in working capital levels and quarterly free cash flow results. As a result of such quarterly fluctuations in free cash flow results, we believe that quarter-to-quarter comparisons of our results of operations may not necessarily be meaningful and should not be relied upon as indicators of future performance.

Regulations

Increased audit, review, investigation and general scrutiny by U.S. government agencies of performance under government contracts and compliance with the terms of those contracts and applicable laws could affect our operating results. Negative publicity and increased scrutiny of government contractors in general, including us, relating to government expenditures for contractor services and incidents involving the mishandling of sensitive or classified information as well as the increasingly complex requirements of the DoD and the United States intelligence community, including those related to cybersecurity, could impact our ability to perform in the markets we serve.

International Sales

International revenue, including foreign military sales, foreign military financing, and direct commercial sales, accounted for approximately 4% and 6% of our revenue for the years ended December 31, 2019 and 2018, respectively. Since our focus is primarily with the DoD and our investments are focused as such, we anticipate that international sales will continue to account for a similar percentage of revenue in the future. We remain subject to the spending levels, pace and priorities of the U.S. government as well as international governments and commercial customers, and to general economic conditions that could adversely affect us, our customers and our suppliers.

Additionally, international sales may expose us to foreign exchange fluctuations and changing dynamics of foreign competitiveness based on variations in the value of the U.S. dollar relative to other currencies. The impact of those fluctuations is reflected throughout our Consolidated Financial Statements, but in the aggregate, did not have a material impact on our results of operations for the year ended December 31, 2019 and 2018.

Acquisitions

We consider the acquisition of businesses and investments that we believe will expand or complement our current portfolio and allow access to new customers or technologies. We also may explore the divestiture of businesses that no longer meet our needs or strategy or that could perform better outside of our organization.

Components of Operations

Revenue

Revenue consists primarily of product related revenue, generating 82% and 78% of our total revenues for the periods ended December 31, 2019 and 2018, respectively. The remaining revenue is generated from service related contracts. Additionally, 86% and 82% of our revenue generation for December 31, 2019 and 2018, respectively, is derived from firm-fixed priced contracts. For a firm-fixed price contract, customers agree to pay a fixed amount, negotiated in advance, for a specified scope of

77

work. Revenue on fixed price contracts is generally recognized over time using costs incurred to date relative to total estimated costs at completion to measure progress toward satisfying our performance obligations. Incurred costs represent work performed that corresponds with and thereby best depicts the transfer of control to the customer.

Under flexibly priced contracts, which consists of 14% and 18% of our total revenues for December 31, 2019 and 2018, respectively, we are reimbursed for allowable or otherwise defined total costs (defined as cost of revenues plus allowable general and administrative expenses) incurred, plus a fee. The contracts may also include incentives for various performance criteria, including quality, timeliness, cost-effectiveness or other factors. In addition, costs are generally subject to review by clients and regulatory audit agencies, and such reviews could result in costs being disputed as non-reimbursable under the terms of the contract. Revenue for flexibly priced contracts are generally recognized as services are performed and are contractually billable.

Please refer to “—Critical Accounting Policies and Estimates” and “Note 2: Revenue from Contracts with Customers” in the Notes to our Consolidated Financial Statements.

Cost of Revenues

Cost of revenues includes materials, labor and overhead costs incurred in the manufacturing, design, and provision of products and services sold in the period as well as warranty costs. Material costs include raw materials, purchased components and sub-assemblies and outside processing and inbound freight. Labor and overhead costs consist of direct and indirect manufacturing costs, including wages and fringe benefits, operating supplies, depreciation and amortization, occupancy costs, and purchasing, receiving, inspection costs and inbound freight costs.

General and Administrative Expenses

General and administrative expenses include general and administrative expenses not included within cost of revenues such as salaries, wages and fringe benefits, facility costs and other costs related to these indirect functions. Additionally, general and administrative expenses include internal research and development costs as well as expenditures related to bid and proposal efforts. We expect general and administrative expenses will be impacted by the costs associated with being a publicly-traded company.

Results from Operations

The following discussion of operating results is intended to help the reader understand the results of operations and financial condition of the Company, as well as individual segments, for the year ended December 31, 2019 as compared to the year ended December 31, 2018. Given the nature of our business, we believe revenue and earnings from operations are most relevant to an understanding of our performance at a business and segment level. Our operating cycle is lengthy and involves various types

78

of production contracts and varying delivery schedules. Accordingly, operating results in a particular year may not be indicative of future operating results.

Year Ended December 31, 2019 Compared to the Year Ended December 31, 2018

Our operating results for the year ended December 31, 2019 demonstrate the impact of our cost-effective solutions, strong customer relationships and ability to remain nimble and quick-to-market when it comes to addressing current and future customer needs. During the year we demonstrated the benefit of our flexibility with awards on various urgent operational needs programs across each of our segments, highlighted by a production ramp on our active protection system program within our IMS segment. These programs highlighted our ability to rapidly deploy complex solutions to solve our customers’ evolving requirements. Such ability coupled with our diverse existing installed base of product offerings assisted in driving $2,714 million in revenue, which represents year over year growth of 16.3%. We believe double

79

digit revenue growth coupled with new bookings exceeding revenue, and a robust backlog of $2.8 billion as of December 31, 2019 create a foundation for continued revenue growth. Our profit growth continues to expand in excess of our revenue results driving an operating earnings increase of 262.2% to $163 million in 2019 from our 2018 results of $45 million. The operating earnings growth is attributed to our 16.3% revenue growth and the associated contribution margin and a reduction in acquired asset amortization. The reduction in acquired asset amortization is a result of the full amortization of the intangible assets established when US Holding acquired DRS in 2008, resulting in reduced expenditures of $84 million. The increase in revenue growth was offset slightly by an increase in general and administrative expenses of 3.4% driven by compliance and quality infrastructure expansion to support the revenue growth. Offsetting the general and administrative expenditure increase was a reduction in bid and proposal expenditures on a jet aircraft training program within our AST segment of $24 million. As a consequence, net earnings improved to $75 million for the year ended December 31, 2019 from a loss of $10 million for the year ended December 31, 2018. Adjusted EBITDA, one of our key financial operating metrics also increased 25.0% to $234 million, expanding our Adjusted EBITDA Margin 60 basis points to 8.6%. The increase in Adjusted EBITDA Margin is attributed to lower general and administrative expenses as a percentage of revenues highlighted by a reduction in bid and proposal expenditures primarily related to the aforementioned jet aircraft training program pursuit, offset in part by additional costs incurred on development programs at our IMS segment.

Revenue

Revenue increased $381 million, or 16.3%, from $2,333 million for the year ended December 31, 2018 to $2,714 million for the year ended December 31, 2019. This revenue growth was primarily due to the rapid development and sale of desired capabilities within our IMS segment, highlighted by the active protection system and our Counter Unmanned Aerial System (CUAS) programs. The active protection system and CUAS programs generated revenue growth of over $245 million and $29 million. respectively. to support urgent operational needs. Additionally, our AST segment revenue increased $56 million as a result of the award related production of a next generation weapon sight program. Our NC&C Segment also generated additional revenue attributed to a newly awarded radar manufacturing program generating incremental revenue of $40 million. However, the increases in NC&C revenue was partially offset by decreases as a result of the production transition on our MFOCS ruggedized computing program as we migrated from our mature full rate production contract to our newly awarded five-year indefinite delivery, indefinite quantity contract modernizing the system capability and cyber protection. The new MFOCS program required achievement of certain certifications prior to progressing into full rate production, reducing revenue as compared to the prior year by $52 million.

Cost of Revenues

Cost of revenues increased $336 million, or 17.5%, from $1,919 million for the year ended December 31, 2018 to $2,255 million for the year ended December 31, 2019, driven primarily by the 16.3% increase in revenue described above. The increase in cost of revenues was further impacted by increased costs realized on certain fixed-price development efforts at our IMS segment primarily related to our on-the-move surveillance program for an international customer of $9 million and to certain newly awarded transportation and logistics programs totaling $8 million.

Gross profit increased $45 million, or 10.9%, from $414 million for the year ended December 31, 2018 to $459 million for the year ended December 31, 2019, primarily driven by the 16.3% year over year revenue growth, partially offset by the impact of cost growth on certain design programs within our IMS segment noted above.

80

General and Administrative Expenses

General and administrative expenses increased $9 million, or 3.4%, from $268 million for the year ended December 31, 2018 to $277 million for the year ended December 31, 2019, primarily as a result of

•$20 million increase in compliance costs and quality infrastructure to support our expanding revenue;

•$4 million increase in costs related to the relocation of certain facilities; and

•$5 million increase in bid proposal and internal research and development expenditures ($2 million and $3 million, respectively) to promote future growth opportunities

This cost growth was largely offset by a reduction in proposal expenditures of $24 million on an aircraft training jet program pursuit in our AST segment that did not recur in 2019.

Despite the increase in general and administrative expenses, as a percentage of revenue our general and administrative expenses decreased 1.3%, from 11.5% to 10.2%, contributing to our overall margin expansion.

Other Operating Expenses, Net

Other operating expenses increased $2 million, or 25.0%, from $8 million for the year ended December 31, 2018 to $10 million for the year ended December 31, 2019, as a result of facility consolidation efforts implemented at facilities within our IMS segment.

Amortization of Intangibles

Amortization of intangibles decreased $84 million, or 90.3%, from $93 million for the year ended December 31, 2018 to $9 million for the year ended December 31, 2019, driven entirely by the completion of the amortization of the intangible asset recorded in connection with the 2008 acquisition of DRS by US Holding in December 2018. The remaining intangible asset amortization is primarily attributed to our intangibles assets recorded in connection with our 2017 acquisition of Daylight Solutions Inc. (“Daylight Solutions”), which operates within our AST segment.

Operating Earnings

Operating earnings increased by $118 million, or 262.2%, from $45 million for the year ended December 31, 2018 to $163 million for the year ended December 31, 2019, primarily attributable to increased gross profit driven by higher revenue output from our IMS segment as well as a reduction in the amortization of acquired intangibles.

Interest Expense

Interest expense increased by $7 million, or 12.1%, from $58 million for the year ended December 31, 2018 to $65 million for the year ended December 31, 2019, primarily driven by the commencement of certain financing leases entered into by the Company to enhance our capacity within our NC&C and IMS segments. Additionally, increasing working capital requirements, predominately on fixed price development programs, drove incremental revolver borrowing needs throughout much of 2019, impacting our interest expense accordingly.

81

Other, Net

Other, net remained consistent year over year and consists primarily of non-service related pension expenditures.

Earnings (Loss) Before Taxes

Earnings (loss) before taxes increased $112 million compared to a loss of $17 million for the year ended December 31, 2018 to earnings of $95 million for the year ended December 31, 2019, primarily due to increased revenue and related gross profit, coupled with the reduction of amortization of acquired intangibles.

Income Tax (Provision) Benefit

Income tax (provision) benefit changed by $27 million from an income tax benefit of $7 million for the year ended December 31, 2018 to an income tax provision of $20 million for the year ended December 31, 2019 due to our loss before taxes in 2018 as compared to earnings before taxes in 2019. Our effective tax rate for 2019 and 2018 was 21.1% and 41.2%, respectively. As of December 31, 2019 the Company has $246 million of federal net operating losses and $21 million of net credit carryforwards that can be utilized to reduce approximately $75 million of future federal tax liabilities prior to their expiration beginning in 2025.

Net Earnings (Loss)

Net earnings (loss) increased by $85 million from a loss of $10 million for the year ended December 31, 2018 to earnings of $75 million for the year ended December 31, 2019, primarily due to the increase in revenue and decrease in amortization of acquired intangibles in 2019 as compared to 2018 described above.

Basic, Diluted and Adjusted EPS

For year ended December 21, 2019, Basic, Diluted and Adjusted EPS are $750,000 per share representing an increase of $850,000 per share from the $100,000 loss per share during the fiscal year ended December 31, 2018. The increased EPS was primarily due to improved operating results and decreased intangible asset amortization noted above.

Adjusted EBITDA

Adjusted EBITDA increased $47 million, or 25.0%, from $187 million for the year ended December 31, 2018 to $234 million for the year ended December 31, 2019, primarily due to revenue growth offset in part by increased cost estimates on fixed-priced development programs at our IMS sector and an slight increase in general and administrative expenses.

Adjusted EBITDA Margin

Adjusted EBITDA Margin increased from 8.0% for the year ended December 31, 2018 to 8.6% for the year ended December 31, 2019, primarily due to improved performance from revenue growth outpacing growth in our general and administrative expenses, offset in part by the development program cost growth noted above.

Backlog

Backlog increased by $160 million, or 6.0%, from $2,684 million for the year ended December 31, 2018 to $2,844 million for the year ended December 31, 2019 due to our bookings outpacing our revenue generation during the year, driving an increase in our funded backlog of $209 million. The backlog increase was driven by our AST and NC&C segments as detailed in our operating segments review

82

below. This was offset in part by a decrease in unfunded backlog of $49 million, primarily due to additional funding allocation on our Columbia-class submarine program within our IMS segment.

Estimated Potential Remaining Contract Value

Estimated potential remaining contract value increased $145 million to $8,198 million as compared to the December 2018 balance. The increased is attributed to the contract award received to provide 5+ years of technology upgrades on Naval Submarines totaling $700 million and a MFOCS support contract received to facilitate hardware installation capabilities totaling $233 million. These increases were offset in part by incremental funding received on our IDIQ and follow-on funding programs. Segment funding received on long-term contractual positions totaled $254 million, $384 million and $150 million for AST, NC&C and IMS, respectively.

Leverage Ratio

Our leverage ratio decreased by 0.7x, or 23.4%, from 3.0x for the year ended December 31, 2018 to 2.3x for the year ended December 31, 2019, due to our net debt decreasing by $33 million from December 31, 2018 as compared to December 31, 2019. Net debt declined as a result of additional cash generated during the year and issued to US Holding at December 31, 2019 in the form of a note receivable of $100 million. This reduction of net debt was offset in part by lease debt realized with the commencement of capital leases at our NC&C and IMS segments. The increase in Adjusted EBITDA noted above further reduced our leverage ratio.

Bookings

Bookings increased by $44 million, or 1.5%, from $2,879 million for the year ended December 31, 2018 to $2,923 million for the year ended December 31, 2019 primarily due to the enhanced scoping received on our Columbia-class submarine programs at our IMS segment, largely offset by a reduction in certain competitive C4I network hardware programs with the U.S. Navy.

Free cash flow

Free cash flow increased $45 million, or 69.2%, from $65 million for the year ended December 31, 2018 to $110 million for the year ended December 31, 2019. The increased free cash flow performance is attributed to the increased Adjusted EBITDA noted above coupled with a one-time increase in accounts payable as of December 31, 2019 as compared to December 31, 2018. This was largely offset by an increase in contract assets related primarily to design programs for which we had not yet achieved billable milestones as of the fiscal year end.

Year Ended December 31, 2019 Compared to the Year Ended December 31, 2018

AST

Revenue: AST’s revenue increased $122 million, or 18.5%, from $659 million for the year ended December 31, 2018 to $781 million for the year ended December 31, 2019. This growth was primarily attributed to revenue realized from program awards received in 2018 and 2019 including progress related to the following:

•$56 million due to ramp up efforts on our newly awarded next generation weapon sight program;

•$12 million from ramp up efforts on our newly awarded mobile protected firepower (MPF) program;

•$30 million attributed to increased demand for legacy sensing programs on ground vehicles; and

•$10 million due to incremental effort on our pilot training systems programs.

84

This was offset in part by program delays on certain fixed-price sensors and precision targeting development programs, reducing revenue by $15 million.

Adjusted EBITDA and Adjusted EBITDA Margin: AST’s Adjusted EBITDA increased by $21 million, or 28.8%, from $73 million for the year ended December 31, 2018 to $94 million for the year ended December 31, 2019. Adjusted EBITDA Margin increased from 11.1% for the year ended December 31, 2018 to 12.0% for the year ended December 31, 2019. The increase in Adjusted EBITDA and margin expansion are attributable to the $122 million increase in revenue combined with a reduction in general and administrative expenses as a percentage of sales related to costs for our pursuit of a training jet aircraft training program totaling $24 million that did not recur in 2019. Partially offsetting this Adjusted EBITDA expansion was cost growth on certain sensors and precision targeting fixed-price development programs of $5 million.

Bookings: AST’s bookings increased $38 million, or 4.2%, from $915 million as of December 31, 2018 to $953 million as of December 31, 2019 as a result of incremental awards received on next generation weapon sight programs and increased sensor upgrades on legacy ground vehicle sensing programs as well as awards received supporting naval radar systems . These programs generated incremental orders of $67 million, $23 million and $27 million, respectively. These expansions were offset in part by accelerated program awards in 2018 related to airborne force protection programs totaling $80 million.

Backlog: AST’s backlog increased $196 million, or 17.9%, from $1,098 million as of December 31, 2018 to $1,294 million as of December 31, 2019, primarily due to our bookings performance out-pacing revenue by $172 million coupled with additional unfunded backlog increases. The backlog expansion was highlighted by our awards on the next generation weapon sight program noted above which generated backlog of $52 million in 2019.

Estimated Potential Remaining Contract Value: AST’s estimated potential remaining contract value declined $253 million attributed to funding received on our long-term contractual positions including our aircraft survivability programs of $151 million, soldier sensing programs of $55 million and legacy sensing programs of $30 million.

NC&C

Revenue: NC&C revenue decreased $57 million, or 5.2%, from $1,111 million for the year ended December 31, 2018 to $1,053 million for the year ended December 31, 2019 as a result of the production transition on two of our foundational programs, MFOCS ruggedized computing program and our Technology Hardware Upgrade (TIH) programs, as we migrated from our mature full rate production contract to our newly awarded contracts. The new programs required achievement of certain certifications prior to progressing into full rate production, which resulted in a reduction of revenues of $52 million and $20 million as compared to the prior year, respectively. This was largely offset by progress on newly awarded naval radar production programs received in 2018, which generated additional revenue of $40 million.

Adjusted EBITDA and Adjusted EBITDA Margin: NC&C’s Adjusted EBITDA increased $3 million, or 4.2%, from $72 million for the year ended December 31, 2018 to $75 million for the year ended December 31, 2019. Adjusted EBITDA Margin increased from 6.5% for the year ended December 31, 2018 to 7.1% for the year ended December 31, 2019. The year over year profitability increase was primarily attributable to the successful production transition to the newly awarded MFOCS program, which generated incremental $8 million of margin contribution despite the reduction in revenues noted above.

Bookings: NC&C’s bookings decreased $90 million, or 7.8%, from $1,158 million as of December 31, 2018 to $1,068 million as of December 31, 2019, due to a reduction in competitive awards on certain U.S. Navy hardware programs resulting in a decline of $102 million and the completion of existing submarine hardware upgrade programs in 2018. Despite being successful in our pursuit for the follow-on submarine hardware upgrade program, funding levels in 2019 were limited to initial funding values, which were $51

85

million lower than the 2018 levels. This was offset in part by our ruggedized computing battle management modernization programs awarded in 2019, contributing an incremental $23 million in bookings for the year.

Backlog: NC&C's backlog increased $24 million, or 3.2%, from $752 million as of December 31, 2018 to $776 million as of December 31, 2019, due to bookings of $1,068 million slightly exceeding our revenues recognized of $1,053 million. This increase is due to our ruggedized computing and diagnostics programs on land vehicles offset in part by the reduction in bookings received on competitive naval hardware programs.

Estimated Potential Remaining Contract Value: NC&C’s estimated potential remaining contract value increased $548 million driven by the contract awards to provide technology upgrades on Naval Submarines of $700 million and the contract received to provide installation support for our MFOCS computing hardware of $233 million, offset by funding received on our long-term contract positions. The funding received includes $228 million on naval computing efforts, $126 million on satellite network programs and $30 million on land based computing awards.

IMS

Revenue: IMS revenue increased $307 million, or 50.3%, from $610 million for the year ended December 31, 2018 to $917 million for the year ended December 31, 2019. The increase in revenue was predominantly attributable to our successful rapid development and deployment of our urgent operational needs force protection programs including our active protection system program as well as counter unmanned aerial systems. In total, our force protection programs generated incremental revenue of $274 million as compared to 2018 results.

Adjusted EBITDA and Adjusted EBITDA Margin: IMS’s Adjusted EBITDA increased $22 million, or 53.7%, from $41 million for the year ended December 31, 2018 to $63 million for the year ended December 31, 2019. The increase in Adjusted EBITDA was primarily driven by the increased revenue contribution resulting from our force protection programs. Adjusted EBITDA Margin increased from 6.7% for the year ended December 31, 2018 to 6.9% for the year ended December 31, 2019. The increase was driven by a reduction in general and administrative expenses as a percentage of revenue in 2019 as compared to 2018, creating volume leverage that increased overall profitability.

Bookings: Bookings increased $96 million, or 11.9%, from $806 million as of December 31, 2018 to $902 million as of December 31, 2019. The increase was driven by increased content awarded on our submarine programs with the U.S. Navy of $67 million and incremental funding on the APS program with the U.S. Army generating $16 million of additional bookings. This was offset in part by certain transport and logistics program transitions, including our bridging program which saw reduced order quantity as we transitioned from development to low-rate initial production awards reducing bookings by $19 million.

Backlog: Backlog decreased $60 million, or 7.2%, from $834 million as of December 31, 2018 to $774 million as of December 31, 2019, primarily due to revenue exceeding bookings on our APS program as we accelerated progress to rapidly deploy force protection capability to the U.S. Army. This was offset in part by incremental funding received on our submarine programs as noted above.

Estimated Potential Remaining Contract Value: IMS’s estimated potential remaining contract value decreased $150 million attributed to funding received on our long-term contractual positions including on our military transportation and logistics programs of $62 million, force protection programs of $36 million and $34 million on naval power programs.

See “—Key Financial and Operating Measures—Non-GAAP Financial Measures” above for reconciliations of these measures to the most directly comparable financial measure calculated and presented in accordance with U.S. GAAP.

Liquidity and Capital Resources

We endeavor to ensure the most efficient conversion of operating income into cash for deployment in our business and to maximize shareholder value through cash deployment activities. In addition to our cash position, we use various financial measures to assist in capital deployment decision-making, including cash provided by operating activities and free cash flow, a non-GAAP measure described in more detail below. We believe that the combination of our existing cash, access to credit facilities as described in Note 11: Debt and future cash that we expect to generate from our operations will be sufficient to meet our short and long-term liquidity needs. There can be no assurance, however, that our business will continue to generate cash flow at current levels or that anticipated operational improvements will be achieved. We may also pursue acquisitions or other strategic priorities that will require additional liquidity beyond the liquidity we generate through our operations. Our cash balance as of December 31, 2019 was $85 million compared to $79 million as of December 31, 2018.

The following table summarizes our cash flows for the periods presented:

	Year ended December 31,
(Dollars in millions)	2019		2018
Net cash provided by operating activities	$	157	$	105
Net cash used in investing activities	(151)		(46)

Year Ended December 31, 2019 Compared to the Year Ended December 31, 2018

Operating Activities

We generated cash from operating activities of $157 million for the year ended December 31, 2019 and $105 million for the year ended December 31, 2018. The primary driver of cash inflow improvement is attributed to the increase in operating earnings noted above coupled with an increase in current liabilities including accounts payable of $156 million as of December 31, 2019 as compared to December 31, 2018,

87

generating additional cash from operating activities. This was largely offset by a $166 million increase in contract assets related primarily to certain design programs for which we had not yet achieved billable milestones as of year end. The cash increase was further offset by our payments on finance interest-related expenditures which increased $4 million from 2018 to a total of $59 million in 2019, the majority of which were to our parent company, US Holding.

Investing Activities

Cash used in investing activities was $151 million for the year ended December 31, 2019 and $46 million for the year ended December 31, 2018. The primary use of cash for investing activities is driven by a $100 million intercompany loan to our parent company US Holding generated from excess cash on hand as of December 31, 2019, which was subsequently repaid in January of 2020. Additionally, we increased capital expenditures attributed to capacity expansions to support our recent program awards at our AST segment.

Financing Activities

Cash used in financing activities for the year ended December 31, 2019 and December 31, 2018 was $1 million and $30 million, respectively. Cash used in financing activities was for principal payments on the term loan used to acquire Daylight Solutions of $15 million and $10 million, respectively, for 2019 and 2018. Additionally, in 2018 we paid $13 million of contingent consideration to the former owners of Daylight Solutions predicated on the achievement of prenegotiated operational targets. These outflows were partially offset by additional borrowings made during the year.

Free Cash Flow

Free cash flow increased $45 million, or 69.2%, from $65 million for the year ended December 31, 2018 to $110 million for the year ended December 31, 2019. The increase in free cash flow was mainly due to the increases in cash provided by operating activities noted above partially offset by an increase in capital expenditures.

Contractual Obligations

As of December 31, 2019, our contractual obligations were as follows:

	Payments Due by Period

Off-Balance Sheet Arrangements

As of December 31, 2019, we do not have any significant off-balance sheet arrangements.

Critical Accounting Policies and Estimates

The following is not intended to be a comprehensive list of all of our accounting policies. Our significant accounting policies are more fully described in Note 1: Summary of Significant Accounting Policies to the Consolidated Financial Statements. In many cases, the accounting treatment of a particular transaction is dictated by accounting principles generally accepted in the United States of America. Other areas require management's judgment to make estimates and assumptions that affect the reported amounts of assets and liabilities and the reported amounts of revenues and costs and expenses during the reporting period. Ultimately, actual amounts may differ from these estimates. We believe that critical accounting estimates have the following attributes: (1) they require management to make assumptions about matters that are uncertain at the time of the estimate; and (2) different estimates we reasonably could have used, or changes in the estimates that are reasonably likely to occur, that would have a material effect on our consolidated financial condition or results of operations.

We believe the following critical accounting policies contain the more significant judgments and estimates used in the preparation of our Consolidated Financial Statements.

•Revenue Recognition and Contract Estimates

•Reviews for Impairment of Goodwill and Long-Lived Assets

•Pension Assumptions

•Income Taxes

Revenue Recognition on Contracts and Contract Estimates

We recognize revenue from contracts with customers using the five-step model prescribed in ASC 606. Substantially all of our contracts are accounted for using the over time, cost-to-cost accounting method as determined by the ratio of cumulative costs incurred to date to estimated total contract costs at completion. We believe this is an appropriate measure of progress toward satisfaction of performance obligations as this measure most accurately depicts the progress of our work and transfer of control to our customers.

Revenue and cost estimates for substantially all over time contract performance obligations are reviewed and updated quarterly. Contract estimates are based on various assumptions to project the outcome of future events that can span multiple years. These assumptions include labor productivity and availability, the complexity of the work to be performed, the cost and availability of materials, the performance of subcontractors and the availability and timing of funding from the customer. Changes in estimates affecting sales, costs and profits are recognized in the period in which the change becomes known using the cumulative catch-up method. Under this method, the impact of the adjustment on profit recorded to date on a contract is recognized in the period the adjustment is identified. Revenue and profit in future periods of contract performance are recognized using the adjusted estimate. The aggregate impact of adjustments in contract estimates are $55 million and $26 million for 2019 and 2018 respectively. The changes in estimates are primarily attributed to changes in our firm-fixed-priced development type programs. As changes happen in the design to meet required specifications, those changes often result in changes to the overall profitability of the programs. Our contract reviews are conducted at least quarterly in which we incorporate our best estimate to complete the program known at that point in time.

For further discussion, see Note 2: Revenue from Contracts with Customers to the Consolidated Financial Statements.

89

Reviews for Impairment of Goodwill and Long-lived Assets

Goodwill represents the excess purchase price paid to acquire a business over the fair value of net assets acquired. We review goodwill for impairment annually at each of our reporting units or when changes in circumstances indicate that the carrying value may not be recoverable. Such circumstances include a significant adverse change in the business climate for one of our reporting units or a decision to dispose of a reporting unit or a significant portion of a reporting unit.

We use both qualitative and quantitative approaches when testing goodwill for impairment. When determining the approach to be used, we consider the current facts and circumstances of each reporting unit as well as the excess of each reporting unit’s estimated fair value over its carrying value based on our most recent quantitative assessments. Our qualitative approach evaluates the business environment and various events impacting the reporting unit including, but not limited to, macroeconomic conditions (e.g., impact of COVID-19), changes in the business environment and reporting unit-specific events. If, based on the qualitative assessment, we determine that it is more likely than not that the fair value of a reporting unit is greater than its carrying value, then a quantitative assessment is not necessary. However, if a quantitative assessment is determined to be necessary, we estimate the fair value of the reporting unit and compare that to its carrying value. To the extent the carrying value exceeds the fair value of a reporting unit, an impairment is recorded for the amount equal to this excess.

Our estimate of fair value is based primarily on the discounted projected cash flows of the underlying operations and requires the use of judgment by management. The process requires numerous assumptions, including the timing of work embedded in our backlog, our performance and profitability under our contracts, our success in securing future business and the appropriate risk adjusted interest rate used to discount the projected cash flows. Due to the variables inherent in our estimates of fair value, differences in assumptions may have a material effect on the result of our impairment analysis.

As of December 31, 2019, we completed quantitative assessments for our reporting units and the fair value of each reporting unit exceeded its carrying value. As a result, no impairments to goodwill were recorded.

Long-lived assets held for use, which primarily includes finite-lived intangible assets and property, plant and equipment, are evaluated for impairment whenever events or circumstances indicate that the undiscounted net cash flows to be generated by their use over their expected useful lives and eventual disposition are less than their carrying value. The long-term nature of these assets requires the estimation of their cash inflows and outflows several years into the future and only takes into consideration technological advances known at the time of the impairment test.

Pension Assumptions

Our defined-benefit pension and other post-retirement benefit costs and obligations depend on several assumptions and estimates. The key assumptions include interest rates used to discount estimated future liabilities and projected long-term rates of return on plan assets. The expected long-term rate of return is based on the market expectations at the beginning of the period for returns over the entire life of the related obligation. These retirement plan assumptions are based on our best judgment, including consideration of current and future market conditions. In the event any of the assumptions change, pension and other post-retirement benefit cost could increase or decrease. For further discussion about our retirement plan assumptions, see Note 12:Pension and Other Postretirement Benefits to the Consolidated Financial Statements.

Income Taxes

We account for income taxes under the asset and liability method in accordance with the accounting standard for income taxes. The asset and liability method requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the carrying

90

amounts and tax bases of assets and liabilities. Under this method, changes in tax rates and laws are recognized in income in the period such changes are enacted.

We record net deferred tax assets to the extent we believe these assets will more likely than not be realized. In making such determination, we consider all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax planning strategies and recent results of operations. If we were to determine that we would be able to realize our deferred income tax assets in the future in excess of their net recorded amount or would no longer be able to realize our deferred income tax assets in the future as currently recorded, we would make an adjustment to the valuation allowance which would decrease or increase the provision for income taxes.

The provision for federal, state, foreign and local income taxes is calculated on income before income taxes based on current tax law and includes the cumulative effect of any changes in tax rates from those used previously in determining deferred tax assets and liabilities. Such provision differs from the amounts currently payable because certain items of income and expense are recognized in different reporting periods for financial reporting purposes than for income tax purposes.

We recognize liabilities for uncertain tax positions when it is more likely than not that a tax position will not be sustained upon examination and settlement with various taxing authorities. Liabilities for uncertain tax positions are measured based upon the largest amount of benefit that is greater than 50% likely to be realized upon ultimate settlement. We recognize interest and penalties related to uncertain tax positions in our income tax expense.

As of December 31, 2019, we had gross deferred tax assets of $178 million and deferred tax asset valuation allowances of $14 million. The deferred tax assets principally relate to benefit accruals, inventory obsolescence, tax benefit carryforwards and contract reserves. The deferred tax assets include $69 million related to tax benefit carryforwards associated with net operating losses.

Accounting Standards Updates (ASU)

See Note 1: Summary of Significant Accounting Policies to the Consolidated Financial Statements for information regarding accounting standards we adopted in 2019 and other new accounting standards that have been issued by the Financial Accounting Standards Board but are not effective until after December 31, 2019.

Quantitative and Qualitative Disclosure of Market Risks

Equity Risk

We currently have limited risk related to fluctuations in marketable securities. Outside of pension assets which are disclosed in Note 12: Pension and Other Postretirement Benefits to the Consolidated Financial Statements, the only investments the Company holds are overnight money market accounts. Fluctuations are unlikely and would have limited impact on the financial statements of the Company.

Interest Rate Risk

We are exposed to interest rate risk on variable-rate borrowings under our revolving credit facilities, for which no amounts were outstanding as of December 31, 2019. Our remaining debt facilities are fixed rate obligations and not subject to fluctuations in interest rates.

Foreign Currency Risk

In certain circumstances, we may be exposed to foreign currency risk. However, as the overwhelming majority of our revenue is derived from U.S. sources directly as a prime contractor or indirectly as a subcontractor for the U.S. government as end-customer, we have limited foreign currency exposure. Currently our exposure is primarily with the Canadian dollar and limited to receivables owed of $60 million

91

as of December 31, 2019. A 10% fluctuation in exchange rates would not have a material impact on our financial statements. We do not enter into or issue derivative instruments for trading purposes.

Inflation Risk

We have generally been able to anticipate increases in costs when pricing our contracts. Bids for longer-term firm fixed-price contracts typically include assumptions for labor and other cost escalations in amounts that historically have been sufficient to cover cost increases over the period of performance.

U.S. Defense Market Trends and Market Opportunities

Our core markets have experienced strong growth. The DoD defense budget has grown at a CAGR of 5.8% from 2016 to 2019, reflecting the shift of the DoD’s priorities from a focus on global terrorism to emerging threats from more sophisticated and technologically advanced adversaries requiring enhanced capabilities across the DoD. Additionally, we foresee growth opportunities in foreign military sales and direct commercial sales, particularly as international allies require similar force modernization.

The DoD is our largest customer and, for the year ended December 31, 2019, accounted for approximately 89% of our business as an end-user, with revenues principally derived directly or indirectly from contracts with the U.S. Army and U.S. Navy, which represented 40% and 36%, respectively, of our total revenues for the year ended December 31, 2019. The stated U.S. National Defense Strategy is to “compete, win and deter” in a challenging and complex international security environment. The current landscape is defined by rapid technological change and competition from emerging peer and near-peer adversaries who are nation states that are becoming great powers. Every domain of U.S. military advantage is expected to be contested, including air, land, sea, space and cyberspace. U.S. forces facing these new threats are in need of modernization as readiness has been strained following nearly two

94

decades of continuous conflict with both traditional and novel adversaries. In order to face these challenges, the U.S. military will likely need to balance limited resources between new high-cost technological capabilities and upgrades of existing equipment.

In today’s threat environment, the U.S. military is positioning itself for non-stop, continuous competition against these rising nation state threats. Military services are increasingly moving towards multi-domain operations that now include both space and cyberspace domains in addition to the air, land and sea domains. The creation of the U.S. Space Force is also expected to drive new requirements for high technology defense capabilities, including increased space sensing and evolution of communications approaches. Even as new spending priorities shift towards addressing high-end threats, the U.S. military knows that it cannot compete with yesterday’s weapons or equipment. Military modernization programs and priorities are expected to provide both opportunities for new solutions and for upgrades to existing platforms. We believe that companies with an existing installed base of hardware will be able to perform upgrades to provide modernization solutions at a lower cost. Companies with strong customer relationships and outstanding execution will more effectively maintain program positions.

In this new military environment, U.S. forces are seeking the ability to sense further from a greater distance and enhance their reach across the spectrum of warfare. Increased use of sensor technologies enables forces to detect threats further and more quickly and deliver rapid, forceful responses. Sensors and laser systems are expected to enable optionally manned and autonomous platforms for the future.

The need for greater situational understanding for the warfighter also drives the need for increased data and communications bandwidth to and from command centers to forward-positioned military platforms and dismounted soldiers. Network computing and communications systems need to provide deployed forces with access to secure data to promote information-sharing and situational understanding for faster decision-making. Battlefield management systems and individual soldier communications systems require secure rugged computing solutions and are becoming increasingly interoperable with current combat air forces and naval computing infrastructure. Encrypted data and cyber protection capabilities aim to ensure that the data U.S. forces receive is trusted and protected from enemies. This capability is intended to allow forces to be more mobile and geographically dispersed while operating with immediate access to trusted information. Satellite communications systems also provide data to U.S. warfighters around the globe and are projected to increasingly utilize satellite constellations at all altitudes for redundancy, lower latency, expanded bandwidth and security.

U.S. forces are in need of greater force protection technologies. Emerging requirements for counter-unmanned aerial systems, active protection, infrared countermeasures and air defense systems require rapid deployment to keep U.S. military platforms and personnel safe from growing threats. The U.S. military is also focusing efforts on transportation and logistics capabilities, ensuring that their trained and equipped personnel and supplies can make it to the battlefield wherever that may be. All of the increased sensing, self-protection, directed energy, communications and computing needs for the warfighter require significantly higher levels of mobile power than in the past. Electrical power generation, conversion, storage and distribution and on-board vehicle power solutions will provide U.S. forces the energy they need in the future to win in this era of competition.

The U.S. military budget accounts for nearly 40% of the world’s defense spending and foreign military allies often select U.S. military solutions to train, equip and modernize their forces to enhance interoperability. Beyond the opportunity for direct commercial and foreign military sales to these foreign countries, many allies leverage U.S. funding and equipment, providing opportunities for U.S. defense contractors offering solutions that can be sold internationally.

The global community is in a period of rapid technological change and new commercial technologies may change society and, ultimately, the character of conflicts. We believe that investing in high technological capabilities, developing proprietary intellectual capability, as well as integrating leading-edge commercial technology into our solutions will provide us with a competitive advantage. New acquisition programs are expected to seek innovative solutions. The need for innovation is more critical

95

than ever, and to accelerate innovation, the DoD has deployed more rapid acquisition methods. We believe that these methods will provide greater opportunities for companies with proven abilities to quickly develop and deploy new technologies. The DoD has placed a high priority on defense procurement reform to speed up the development of new key capabilities, increase responsibility and accountability for major acquisition programs and reduce acquisition risk. As a result, we believe that mid-tier companies, such as DRS, with proven technological capabilities and an agile decision-making structure are positioned to rapidly respond to emerging requirements.

We strategically select the markets where we compete and the programs on which we bid.

•We target programs in markets where we have strong core technology and where the DoD is focused. We seek to compete only in the areas in which we have a technological or market advantage, and which will attract funding. As an example, our core technology in high-performance receivers/transceivers is sought after by our customers for their wide-bandwidth and high signal dynamic range. These features are required for modern EW systems being developed for the U.S. Army, U.S. Marine Corp. and other customers to capture, exploit and/or disrupt modern signals.

•We target our investments in core technologies in areas of high market growth. Our investments fill gaps, create leading market offerings and make capital improvements to our business. We are also awarded, and leverage, significant customer research and development funding to complement our investments.

Executing on Our Programs to Enhance Profitability

We remain focused on continuing to drive operational enhancements and efficiencies, which we believe will result in improved profitability over time. We believe that our world-class technology and innovative solutions coupled with the transition of development programs into production will serve as the foundation for continued profitable growth.

•We believe that outstanding performance and timely execution on our programs will win us new business and lead to profitable growth, including new opportunities for follow-on orders which will add to our growing production base. Our recent short-range air defense program is an example of a program that we were able to win because of our reputation with the customer and our ability to quickly react to their needs.

•Integrated systems offerings of our products and systems should further expand margins as we continue to grow the topline. Our Integrated Missions Systems business, for example, has strong integration capabilities which will enable us to grow content on programs as we increase our role from smaller sub-systems into full systems integration.

Our Columbia-class submarine program is an example of a fixed-price development program that we invested in while recognizing that it will deliver long-term profitable growth, beginning in 2021, when it transitions into production.

•Our APEX program focuses on the achievement of operational savings in production, supply chain and our overall cost structure. The APEX program’s goal is to strive for continuous improvement through unification of our business practices, tools and metrics, ongoing employee training and innovation. Commitment to excellence requires us to challenge ourselves to exceed our customers’ expectations. A culture of continuous improvement will allow us to improve our efficiency and increase our margins.

Actively Managing our Portfolio for Optimization

We manage our portfolio to optimize our growth in areas where we have the strongest core technology base, where we have a competitive cost structure and where the defense market is growing.

•DRS has a portfolio of products and services that we believe are positioned to move up the value chain to provide sub-systems and integrated systems and solutions. We regularly assess our portfolio to ensure strong alignment with our customers’ needs and priorities and consider accretive acquisitions in areas where we have strategic gaps to address our customer’s needs.

•We employ a strategy of active IP management to acquire technologies and IP through partnerships, teaming arrangements, strategic licenses and other business arrangements. This active IP management strategy allows us access to new technologies in a disciplined manner to maintain the strength of our diversified portfolio.

Continue to Take Care of Our People

We seek to recruit and retain the highest caliber of talent through competitive pay and benefits packages, diverse and inclusive personnel policies and fostering an innovative and modern workforce.

•We strive to maintain the highest ethical standards and foster a collaborative workplace to ensure a strong culture in our people.

•We constantly assess and make thoughtful changes to our personnel practices, including changes to our pay and benefits packages and increased training and growth opportunities, to ensure that we attract and retain top talent.

•We have implemented a strong diversity and inclusion program to ensure that our workforce looks like the communities in which they operate. This helps us to bring diverse ideas and perspectives to decision-making and problem-solving and allows us to draw from the largest pool of available talent.

History of the Company

DRS was founded in 1969, in Mount Vernon, New York, as Diagnostic Retrieval Systems, and soon became best known by its acronym, DRS. In 1981, we first became a publicly traded company. Over the subsequent decades, DRS experienced a period of rapid growth driven in large part by numerous acquisitions. In 2008, our stock ceased to be publicly traded when we were acquired by the Italian-headquartered Finmeccanica S.p.A. (now known as Leonardo S.p.A.) and we subsequently rebranded ourselves as Leonardo DRS. Since the Leonardo acquisition, we have operated under agreements with the DoD and related security policies in order to limit our foreign parent’s ability to control our business operations.

Governance Structure

101

Following completion of this offering, we expect that Leonardo S.p.A. will indirectly hold approximately          % of our common stock through US Holding (or        % if the underwriters exercise their option to purchase additional shares from the selling stockholder). As a U.S. defense contractor with high level personal and facility security clearances, DRS, US Holding and Leonardo S.p.A. have entered into an agreement with the DoD to mitigate against the potential for undue foreign ownership control and influence (“FOCI”) on the performance of classified programs by implementing various limitations on US Holding’s and Leonardo S.p.A.’s rights as the direct stockholder and ultimate foreign parent company of DRS, respectively. Specifically, US Holding has authorized certain cleared US persons to operate as its proxies and exercise the key prerogatives of stock ownership. The proxy agreement requires that DRS have the financial and operational ability to operate as an independent entity under an independent board of directors, subject to certain limited, enumerated consent rights of the majority stockholder (including material mergers and acquisitions and incurrence of debt). For additional information, see “Certain Relationships and Related Party Transactions—Transactions with Leonardo S.p.A. Affiliates—Proxy Agreement.”

Our Ultimate Parent

Leonardo S.p.A., a global high-technology company, is among the top ten world players in Aerospace, Defense and Security and Italy’s main industrial company. Organized into five business divisions, Leonardo S.p.A. has a significant industrial presence in Italy, the United Kingdom, Poland and the USA, where it also operates through subsidiaries such as Leonardo DRS (defense electronics), and joint ventures and partnerships: ATR, MBDA, Telespazio, Thales Alenia Space and Avio. Leonardo S.p.A. competes in the most important international markets by leveraging its areas of technological and product leadership (Helicopters, Aircraft, Aerostructures, Electronics, Cyber Security and Space). Listed on the Milan Stock Exchange (LDO), in 2019 Leonardo S.p.A. recorded consolidated revenues of €13.8 billion and invested €1.5 billion in Research and Development. The group has been part of the Dow Jones Sustainability Index (“DJSI”) since 2010 and is named as sustainability global leader in the Aerospace & Defense sector of DJSI for the second year in a row in 2020.

Development

We conduct research and development (“R&D”) activities using our own funds (referred to as company-funded R&D or independent research and development (“IR&D”)) and under contractual arrangements with our customers (referred to as customer-funded R&D) to enhance existing products and services and to develop future technologies. R&D costs include basic research, applied research, concept formulation studies, design, development, and related test activities. IR&D costs are allocated to customer contracts as part of the general and administrative overhead costs and generally recoverable on our customer contracts with the U.S. Government. Customer-funded R&D costs are charged directly to the related customer contract. Substantially all R&D costs are charged to cost of revenues as incurred.

We recorded revenues for customer-funded R&D of approximately $177 million and $148 million for the years ended December 31, 2019 and 2018, respectively. Such customer-funded activities are primarily the result of contracts directly or indirectly with the U.S. government. We also invest in internal R&D. Expenditures for internal R&D amounted to approximately $31 million and $29 million for the years ended December 31, 2019 and 2018, respectively. Additionally, we employ a strategy of active IP management to acquire technologies and IP through partnerships, teaming arrangements, strategic licenses and other business arrangements. This active IP management strategy allows us access to new technologies in a disciplined manner.

We are currently involved in research and development programs and investment projects in each segment. These include, but are not limited to, systems and components for naval propulsion and electrical conversion, soldier sensors, force protection, electronic warfare and computing and networking. We also invest in research and development of disruptive technologies in the fields of artificial intelligence, autonomy, and quantum sensing.

102

Competition

We operate in a highly competitive environment. In the military sector, we compete with large, mid-tier and smaller defense contractors as well as some non-traditional contractors on the basis of product performance, cost, overall value, delivery schedule, embedded positions and reputation. Our products are sold in markets in which several of our competitors are substantially larger than we are, enabling them to devote substantially greater resources to research and development, and they, generally, have greater financial resources, allowing them to better withstand challenging operating conditions. We face a variety of competitors which vary across our segments and specific products. Although we compete with different competitors in each of our segments, our competitors include Raytheon Technologies, L3-Harris, BAE Systems, FLIR, Cubic and Elbit Systems, among others. We frequently partner with or are involved in subcontracting, teaming, supplier and customer relationships with companies that are, from time to time, competitors on other programs. Depending on the project or product, we may depend on parties with whom we complete vigorously on other projects and products. The extent of competition for any single project generally varies according to the complexity of the product and the dollar value of the anticipated award. We generally compete on the basis of:

•The performance, adaptability and price of our products;

•Our reputation for prompt, flexible, and responsive contract performance;

•Our installed base of existing products and track record as a trusted partner;

•Our ability to react to customer and market trends;

•Our strong core technology capabilities and accumulated technical knowledge and expertise;

•The breadth of our product lines;

•Our highly experienced management team and talented workforce; and

•The capabilities of our facilities, equipment and personnel to undertake the programs for which we compete.

Our future success will depend in large part upon our ability to improve existing product lines and to develop new products and technologies in the same or related fields.

Since a number of consolidations and mergers of defense suppliers have occurred, the number of participants in the defense industry has decreased in recent years. We expect this consolidation trend to continue. As the industry consolidates, the large defense contractors are narrowing their supplier base, awarding increasing portions of projects to strategic mid- and lower-tier suppliers, and, in the process, are becoming oriented more toward systems integration and assembly. We believe that while this defense industry trend presents challenges, it also presents opportunities in certain markets.

Manufacturing and Supplies

Our manufacturing processes for our products include the assembly of purchased components and subsystems and testing of products at various stages in the assembly process. Purchased components include integrated circuits, circuit boards, metal fabricated into cabinets, resistors, capacitors, semiconductors, silicon wafers and other materials, wire and cables and subsystems including, but not limited to, off-the-shelf components such as servers, computers and peripherals. In addition, many of our products use castings and machined housings.

The manufacturing process for certain of our optic products includes the grinding, polishing and coating of various optical materials and the machining of metal components. Although materials and purchased components generally are available from a number of different suppliers, several suppliers are our sole source of certain components. If a supplier should cease to deliver such components we expect

103

that other sources would be available; however, added cost and manufacturing delays might result. We occasionally experience delays attributable to supply shortages and quality and other related problems with respect to certain components, such as semiconductors and connectors. In addition, for our optical products, certain materials, such as rare earth materials, germanium, and zinc sulfide may not always be readily available.

Intellectual Property

We have patents on certain of our technologies and methods, semiconductor devices, rugged computer-related items and electro-optical and infrared focal plane array products, in addition to other technologies and methods. We and our subsidiaries have certain registered trademarks, none of which are considered material to our current operations. We also hold certain trade secrets without formal patent filings in order to protect them from disclosure. We believe our patent position and intellectual property portfolio in the aggregate are valuable to our operations. We do not believe that the conduct of our business as a whole is materially dependent on any single patent, trade secret, trademark or copyright.

When we work on U.S. government contracts or use funding of the U.S. government, the U.S. government may have contractual rights to data for our technologies, source code and other developments associated with such government contracts. Records of our data rights are typically maintained in order to claim these rights as our proprietary technology, but it may not always be possible to delineate our proprietary developments from those developed under U.S. government contracts. The protection of our data from use by other U.S. government contractors is subject to negotiation from time to time between us and the U.S. government. The extent of the U.S. government’s data rights to any particular product generally depends upon whether the product was developed under a government contract and the degree of government funding for the development of such product. While we may retain rights over any technology, product or intellectual property that we develop under U.S. government contracts or using funding of the U.S. government, this requires us to take timely affirmative measures to preserve our right.

Contracts

We derive a significant portion of our revenue from long-term programs and programs for which we are the incumbent supplier or have been the sole or dual supplier for many years. A significant percentage of our revenue is derived from programs that are in the production phase. We also derive revenue from contracts on which we serve as either prime contractor or subcontractor. For the year ended December 31, 2019, revenues were approximately even between contracts on which we served as prime contractor and subcontractor in our AST and IMS segments, whereas in our NC&C segment approximately 62% of revenues were attributable to contracts on which we served as prime contractor and 36% were attributable to contracts on which we served as subcontractor, with the remainder attributable to intersegment sales.

While the majority of our revenue is derived from the U.S. government and DoD, within this we have a diverse business mix with limited dependence on any single contract. No single contract represented more than 10% of revenues for the years ended December 31, 2019 and 2018.

The amount of our revenues attributable to our contracts by contract type during the years ended December 31, 2019 and 2018 were as follows:

	December 31,
($ in millions)	2019		2018
Firm fixed price	$	2,333	$	1,910
Flexibly priced(1)	$	381	$	423

________________

(1)Includes revenue derived from time-and-materials contracts.

104

Typically we enter into three types of contracts: fixed price contracts, cost-plus contracts and time and material (“T&M”) contracts (cost-plus contracts and T&M contracts are aggregated above as flexibly priced contracts). and our contracts are normally for production, services or development. Production contracts are typically the fixed-price type, development contracts are sometimes of the cost-plus-type, and service contracts are sometimes of the time and materials type. We believe continued predominance of fixed-price contracts is reflective of the significant portion of production contracts in our U.S. government contract portfolio. Fixed-price contracts may provide for a fixed price or they may be fixed-price-incentive-fee contracts. Under fixed-price contracts, we agree to perform for an agreed-upon price. Accordingly, we derive benefits from cost savings, but bear the risk of cost overruns. Under fixed-price-incentive-fee contracts, if actual costs incurred in the performance of the contracts are less than estimated costs for the contracts the savings are apportioned between the customer and us. If actual costs under such a contract exceed estimated costs, however, excess costs are apportioned between the customer and us, up to a ceiling. We bear all costs that exceed the ceiling, if any.

Cost-plus type contracts typically provide for reimbursement of allowable costs incurred plus a fee (profit). Under cost-plus-fixed-fee contracts, we are reimbursed for allowable costs and receive a fixed fee, which is negotiated and specified in the contract. Such fees have statutory limits. Unlike fixed-price contracts in which we are committed to deliver without regard to cost, cost-plus contracts normally obligate us to use our best efforts to accomplish the scope of work within a specified time and a stated contract dollar limitation. In addition, U.S. government procurement regulations typically result in lower profits for cost type contracts because of our reduced risk. Under cost-plus-incentive-fee contracts, an additional incentive fee awarded may be based on cost or performance. When the incentive is based on cost, the contract specifies that we are reimbursed for allowable incurred costs plus a fee adjusted by a formula based on the ratio of total allowable costs to target cost. Target cost, target fee, minimum and maximum fee, and adjustment formulae are agreed upon when the contract is negotiated. In the case of performance-based incentives, we are reimbursed for allowable incurred costs plus an incentive, contingent upon meeting or surpassing stated performance targets. The contract provides for increases in the fee to the extent that such targets are surpassed and for decreases to the extent that such targets are not met. In some instances, cost-plus-incentive-fee contracts also may include a combination of both cost and performance incentives. Under cost-plus-fixed-fee contracts, we are reimbursed for costs and receive a fixed fee, which is negotiated and specified in the contract. Time-and-material type contracts provide for reimbursement of labor hours expended at a contractual fixed labor rate per hour, plus the actual costs of material and other direct non-labor costs. The fixed labor rates on time-and-material type contracts include amounts for the cost of direct labor, indirect contract costs and profit.

For the majority of our contracts, revenues are recognized using an over time, cost-to-cost accounting method, with revenue recognized based on the ratio of cumulative costs incurred to date to estimated total contract costs at completion. For contracts accounted for in this way, our reported revenues may contain amounts which we have not billed to customers if we have incurred costs, and recognized related profits, in excess of billed progress payments.

Under U.S. GAAP, contract costs, including allowable general and administrative expenses on certain government contracts, are charged to work-in-progress inventory and are written off to costs and expenses as revenues are recognized. The Federal Acquisition Regulations (“FAR”) and the defense supplement (“DFARS”), incorporated by reference in U.S. government contracts, provide that internal research and development costs are allowable general and administrative expenses. Unallowable costs, pursuant to the FAR, are excluded from costs accumulated on U.S. government contracts.

Our defense contracts and subcontracts that require the submission of cost or pricing data are subject to audit, various profit and cost controls, and standard provisions for termination at the convenience of the customer. The DCAA performs these audits on behalf of the U.S. government. The DCAA has the right to perform audits on our incurred costs on cost-type or price redeterminable-type contracts on a yearly basis. Approval of an incurred cost submission can take from one to three years from the date of the submission of the contract cost.

105

U.S. government contracts are, by their terms, subject to termination by the U.S. government for either convenience or default by the contractor. Fixed-price contracts provide for payment upon termination for items delivered to and accepted by the U.S. government and, if the termination is for convenience, for payment of fair compensation of work performed plus the costs of settling and paying claims by terminated subcontractors, other settlement expenses and a reasonable profit on the costs incurred. Cost-plus contracts provide that, upon termination, the contractor is entitled to reimbursement of its allowable costs and, if the termination is for convenience, a total fee proportionate to the percentage of the work completed under the contract. If a contract termination is for default, however, the contractor is paid an amount agreed upon for completed and partially completed products and services accepted by the U.S. government. In these circumstances, the U.S. government is not liable for excess costs incurred by us in procuring undelivered items from another source.

In addition to the right of the U.S. government to terminate U.S. government contracts, such contracts are conditioned upon the continuing availability of Congressional appropriations. Congress usually appropriates funds for a given program on a September 30 fiscal year basis, even though contract performance may take many years. Consequently, at the outset of a major program, the contract is typically only partially funded, and additional funds normally are committed to the contract by the procuring agency only as appropriations are made by Congress for future fiscal years.

Product Warranties

Product warranty costs generally are accrued in proportion to product revenue realized in conjunction with our over-time revenue recognition policy. Product warranty expense is recognized based on the term of the product warranty, generally one to three years, and the related estimated costs, considering historical claims expense. Accrued warranty costs are reduced as these costs are incurred and as the warranty period expires, and otherwise may be modified as specific product performance issues are identified and resolved.

Joint Ventures, Strategic Investments and Mergers and Acquisitions

From time to time we enter into strategic joint ventures, investments and mergers and acquisitions. We hold a 51% ownership interest in Advanced Acoustic Concepts (“AAC”), a joint venture with a subsidiary of Thales S.A., which provides sonar systems and components, acoustic training systems, and other underwater systems. AAC engages in development of technology, products, and systems and also licenses technology and products from Thales for adaptation to the U.S. market when the opportunities are present. DRS provides support to AAC in the areas of security, export control, human resources, information technology, and at times, financing, among others. DRS chairs the joint management committee and, together with Thales, reviews and approves their business, financials, and business plans, including investments. AAC has provided cash dividends to DRS of approximately $3 million and $5 million for the years ended December 31, 2019 and 2018, respectively.

In June 2017, we acquired Daylight Solutions for a purchase price of $150 million in cash. Daylight Solutions designs and manufactures infrared Quantum Cascade Laser solutions that supplement the infrared sensors already in DRS’ portfolio. Together these two capabilities address the growing force protection needs for aircraft and ground vehicles by allowing them to sense threats and then enact countermeasures for certain classes of enemy missiles, thus saving lives. The acquisition of Daylight also allowed DRS to address markets unrelated to force protection, again by combining the infrared lasers with infrared sensors. To address the growing demands to sense further, and to increase situational understanding, these two capabilities allow for longer-range threat detection.

We also hold an approximately 5% interest in Hoverfly Technologies, Inc. (“Hoverfly”), which designs, develops and manufactures power-tethered unmanned aerial systems and related products. Pursuant to the terms of our agreement with Hoverfly, we will increase our investment in Hoverfly to up to 10% if Hoverfly hits certain sales milestones and may increase our investment beyond 10%, at our option. We have also entered into an exclusive manufacturing and teaming agreement with Hoverfly.

106

Seasonality

We do not consider any material portion of our business to be seasonal. However, our cash flows lack linearity with a majority of cash receipts generally occurring in the fourth quarter of our fiscal year. Various factors can affect the distribution of our revenues and cash flows between accounting periods, including the federal government’s budget cycle based on its October-to-September fiscal year, the timing of government awards, the availability of government funding, the timing of costs incurred (including when materials are received), product deliveries and customer acceptance.

Legislation and Regulation

As a U.S. government contractor, we (and our subcontractors and others with whom we do business) must comply with many significant procurement regulations and other specific legal requirements. These regulations and other requirements increase our performance and compliance costs and risks and regularly evolve. New laws, regulations or procurement requirements or changes to current ones (including, for example, regulations related to cybersecurity, privacy, recovery of employee compensation costs, counterfeit parts, anti-human trafficking, specialty metals and conflict minerals) can significantly increase our costs and risks and reduce our profitability. If we fail to comply with procurement regulations or other requirements we may be subject to civil and/or criminal penalties and/or administrative sanctions, which may include termination or modification of contracts, forfeiture of profits, suspension of payments, fines and suspension or prohibition from doing business with the U.S. government, any of which could have a material adverse effect on our business, financial condition and results of operations. See “Risk Factors—Risks Relating to Our Business—We are subject to a number of procurement, international trade, and other rules regulations and requirements related to our industry, our products, and the businesses we operate. If we fail to comply with such rules, regulations or other requirements we may be subject to civil and/or criminal penalties and/or administrative sanctions.”

We (again, including our subcontractors and others with whom we do business) also are subject to, and expected to perform in compliance with, a vast array of federal laws, regulations and requirements related to our industry, our products and the businesses we operate. These laws and regulations include, but are not limited to the Anti-Kickback Act, the Arms Export Control Act, including the ITAR, the Communications Act, the Defense Federal Acquisition Regulations, the Export Control Reform Act, including the EAR (which includes anti-boycott provisions), the False Claims Act, the Federal Acquisition Regulation, the FCPA, the Lobbying Disclosure Act, the Procurement Integrity Act, the Truthful Cost or Pricing Data Act, the Foreign Trade Regulations, the Foreign Investment Risk Review Modernization Act, the International Emergency Economic Powers Act, the Trading with the Enemy Act, and Executive Orders and regulations, administered by the U.S. Department of the Treasury, Office of Foreign Assets Control, as well as rules and regulations administered by the U.S. Customs and Border Protection and the Bureau of Alcohol, Tobacco, Firearms and Explosives. If we are found to have violated such requirements, we may be subject to reductions of the value of contracts; contract modifications or termination; the withholding of payments from our customer; the loss of export privileges; administrative or civil judgments and liabilities; criminal judgments or convictions, liabilities and consent or other voluntary decrees or agreements; other sanctions; the assessment of penalties, fines, or compensatory, treble or other damages or non-monetary relief or actions; or suspension or debarment.

Our operations include the use, generation and disposal of hazardous materials. We are subject to various U.S. federal, state, local and foreign laws and regulations relating to the protection of the environment, including those governing the discharge of pollutants into the air and water, the management and disposal of hazardous substances and wastes, the cleanup of contaminated sites and the maintenance of a safe workplace. See “Risk Factors—Risks Relating to Our Business—We are subject to environmental laws and regulations, and our ongoing operations may expose us to environmental liabilities affecting our reputation, business, financial condition and results of operations.” Except as described under “Legal Proceedings” below, we believe that we have been and are in material compliance with environmental laws and regulations and that we have no liabilities under environmental requirements that would be expected to have a material adverse effect on our business, results of

107

operations, financial condition or liquidity. It is possible, however, that the ultimate resolution of the matters discussed under “—Legal Proceedings” below could result in a material adverse effect on our results of operations for a particular reporting period, any of which could have a material adverse effect on our business.

Backlog

Our total backlog consists of funded and unfunded amounts. Funded backlog represents the revenue value of orders for services under existing contracts for which funding is appropriated or otherwise authorized less revenue previously recognized on these contracts. Unfunded backlog represents the revenue value of orders for services under existing contracts for which funding has not been appropriated or otherwise authorized less revenue previously recognized on these contracts. In addition to backlog, we also evaluate estimated potential remaining contract value, which represents unexercised options associated with existing firm contracts and primarily includes options and agreements with existing customers to purchase new services. Estimated potential remaining contract value together with backlog represents total estimated contract value The following table summarizes the value of our backlog, estimated potential remaining contract value and total estimated contract value at the respective dates presented.

	December 31,
(Dollars in millions)	2019		2018
Backlog:

Human Capital Resources

As of October 31, 2020, we employed approximately 6,700 people. Approximately 270 of our employees at our West Plains, Missouri facility are represented by a labor union and are covered by a collective bargaining agreement that expires in April 2021 and approximately 210 employees at our Milwaukee, Wisconsin facility are represented by a union and are covered by a collective bargaining agreement that expires in March 2021. We consider our relations with our employees to be good.

Our human capital resources objectives include identifying, recruiting, retaining, incentivizing and integrating our existing and additional employees. The principal purposes of our compensation program are to attract, retain and motivate selected employees through competitive base pay and cash-based performance bonus awards.

Properties

We are headquartered in Arlington, Virginia. Our principal executive offices are leased under a lease agreement expiring in March 31, 2027 with an option to extend for five years thereafter. We also lease space in 17 other states and the District of Columbia in the United States and in one city in Canada and we own properties in three states in the United States and in one city in Canada. We believe that our facilities are adequate for our intended use and sufficient for our immediate needs, including to meet any security certification requirements or requirements for locating facilities in certain locations. It is not certain whether we will negotiate new leases as existing leases expire or whether we will be able to negotiate

108

new leases without substantial cost or at all. Such determinations will be made as existing leases approach expiration and will be based on an assessment of our requirements at that time. Further, we believe that we can obtain additional space, if necessary, based on prior experience and current real estate market conditions. The table below provides additional information about our significant leased and owned facilities and properties.

Legal Proceedings

From time to time, we are subject to certain legal proceedings and claims in the ordinary course of business. These matters are subject to many uncertainties and it is possible that some of these matters ultimately could be decided, resolved or settled in a manner adverse to us. Although the precise amount of liability that may result from these matters is not ascertainable, we believe that any amounts exceeding our recorded accruals should not materially adversely affect our financial condition or liquidity. It is possible, however, that the ultimate resolution of those matters could result in a material adverse effect on our results of operations and/or cash flows from operating activities for a particular reporting period. We establish reserves for specific legal matters when we determine that the likelihood of an unfavorable outcome is probable and the loss is reasonably estimable.

Some environmental laws, such as the Comprehensive Environmental Response, Compensation and Liability Act of 1980 (also known as “CERCLA” or the “Superfund law”) and similar state statutes, can impose liability upon former owners or operators for the entire cost of investigating and remediating contaminated sites regardless of the lawfulness of the original activities that led to the contamination. In July 2000, an entity which later became a subsidiary of the Company received a Section 104(e) Request for Information (“RFI”) from the National Park Service (“NPS”), pursuant to CERCLA, regarding the

110

presence of radioactive material at a site within a national park, which site was operated by an alleged predecessor to our subsidiary over 50 years ago. Following our subsidiary’s response to the RFI, the NPS directed it and another alleged former operator to perform an Engineering Evaluation and Cost Analysis (“EE/CA”) of a portion of the site. Our subsidiary made a good faith offer to conduct an alternative EE/CA work plan, but the NPS rejected this offer and opted to perform the EE/CA itself. The NPS previously posted its intention to open a formal public comment period regarding the EE/CA at the end of 2019. To our knowledge, the EE/CA has not been released and a public comment period has yet to be opened.

Following completion of the EE/CA, the NPS may seek reimbursement for its investigative and remedial efforts to date, or direct one or more of the potentially responsible parties to perform any remediation that may be required by CERCLA or may enter an alternative dispute resolution proceeding to attempt to resolve each party’s share. In addition, the NPS may seek to recover damages for loss of use of certain natural resources. We believe that we have legitimate defenses to our subsidiary’s potential liability and that there are other potentially responsible parties for the environmental conditions at the site, including the U.S. government as owner, operator and arranger at the site. The potential liability associated with this matter could change substantially due to such factors as additional information on the nature or extent of contamination, methods of remediation that might be recommended or required, changes in the apportionment of costs among the responsible parties, whether the NPS seeks to recover additional damages, whether the NPS’s plans to investigate additional areas to identify a need for further remedial action for which the Company may be identified as a potentially responsible party and other actions by governmental agencies or private parties.

Corporate Governance

Board Composition and Director Independence

Our board is composed of seven directors. Our directors will be elected annually to serve until the next annual meeting of stockholders or until their successors are duly elected and qualified. Pursuant to the proxy agreement, Leonardo S.p.A., US Holding, the DCSA and the proxy holders will have specified board designation and/or approval rights following this offering. The proxy agreement requires that our board include the five proxy holders appointed by US Holding after consultation with Leonardo S.p.A. and approval by the DCSA. The proxy agreement also requires that our board to include, four additional directors consisting of our chief executive officer and three additional candidates, selected by the proxy holders in their sole discretion from candidates proposed by US Holding, after reasonable consultation with the nominating and corporate governance committee, subject to approval of the DCSA in certain circumstances. See “Certain Relationships and Related-Party Transactions—Relationship with Leonardo S.p.A Following this Offering—Proxy Agreement.”

While the proxy agreement remains in effect, the number of members on our board will be determined in accordance with the proxy agreement and therefore a fully constituted board will consist of nine directors. During any period when the proxy agreement is not in effect, the number of members on our board may be fixed by majority vote of the members of our board. While the proxy agreement remains in effect, any vacancy in the board that results from the death, disability, resignation, disqualification or removal, or expiration of the term of (i) any proxy holder shall be filled by the new proxy holder appointed

116

to take such proxy holder’s place in accordance with the proxy agreement and (ii) any director who is not a proxy holder shall be filled by the majority vote of the proxy holders, subject to approval of the DCSA in certain circumstances.

Compensation Committee Interlocks and Insider Participation

None of our executive officers serves, or in the past has served, as a member of the board of directors or compensation committee, or other committee serving an equivalent function, of any entity that has one or more executive officers who serve as members of our board of directors or our compensation committee. None of the members of our compensation committee is, or has ever been, an officer or employee of our company.

Board Oversight of Risk Management

Our board believes that effective risk management and control processes are critical to our safety and soundness, our ability to predict and manage the challenges that we face and, ultimately, our long-term corporate success. Our board, both directly and through its committees, is responsible for overseeing our risk management processes, with each of the committees of our board assuming a different and important role in overseeing the management of the risks we face.

Our audit committee is responsible for overseeing risks associated with financial matters including financial reporting, accounting practices and policies, disclosure controls and procedures and internal control over financial reporting. The compensation committee of our board has primary responsibility for risks and exposures associated with our compensation policies, plans and practices, regarding both executive compensation and the compensation structure generally. The nominating and corporate governance committee of our board of directors oversees risks associated with the independence of our board of directors and potential conflicts of interest. The government security committee of our board oversees risks associated with our obligation to safeguard classified information in our possession and our compliance with the proxy agreement and applicable law and regulation including ITAR, EAR, and NISPOM.

Our senior management is responsible for implementing and reporting to our board regarding our risk management processes, including by assessing and managing the risks we face on a day-to-day basis. The role of our board in our risk oversight is consistent with our leadership structure, with our Chief Executive Officer and the other members of senior management having responsibility for assessing and managing our risk exposure, and our board of directors and its committees providing oversight in connection with those efforts. We believe this division of risk management responsibilities presents a consistent, systemic and effective approach for identifying, managing and mitigating risks throughout our operations.

Code of Ethics

Upon completion of this offering, our board will adopt a code of business conduct and ethics that will apply to all of our directors, officers and employees and is intended to comply with the relevant requirements for a code of conduct as well as qualify as a “code of ethics” as defined by the rules of the SEC.

We intend to disclose future amendments to certain provisions of our code of business conduct and ethics, or waivers of such provisions applicable to any principal executive officer, principal financial officer, principal accounting officer and controller, or persons performing similar functions, and our directors, on our website at     as required by applicable law or     requirements. The code of business conduct and ethics will be available without charge on the investor relations portion of our website following this offering.

EXECUTIVE COMPENSATION

COMPENSATION DISCUSSION AND ANALYSIS

INTRODUCTION

The Compensation Discussion and Analysis provides the details of our executive compensation programs and the decisions made as they relate to the Company’s Named Executive Officers (“NEOs”).

The discussion below relates to compensation programs in effect for 2019. Once the compensation of our executive officers has been determined for 2020, we will include the NEOs and their 2020 compensation, and a discussion of 2020 compensation decisions, in the discussion and the tables below.

Compensation Program Overview

Executive Compensation Philosophy

Our executive compensation philosophy is to provide market-based competitive total compensation to support our strategic plan for growth and success, attract and retain executives and other key employees to drive a superior performance culture, and closely link pay to the performance of our executives. Our management team strives to deliver optimal results through focused operational excellence, management of costs and investments, optimization of human capital, leadership, and driving collaboration across our businesses to achieve our strategic goals. The executive compensation and benefit programs are guided by the following principles:

•Pay for Performance. Our program is intended to reward superior past performance and create incentives for future exemplary performance that will create long-term value. To achieve these objectives, our compensation program is designed to reward long-term strategic management and to create a performance-oriented environment.

•Competitive Pay. We target NEO total direct compensation, base salary, annual incentive compensation, and long-term incentive compensation at or around the median of our peers. Our program provides the opportunity for above-median pay for above-median performance and below-median pay for below-median performance.

•Strategic Goals and Metrics. Annual Incentive Compensation (IC) metrics and targets are driven by the Company’s strategic, financial, and operational business goals. Long-Term Incentives (LTI) provide NEOs with a significant personal stake in the long-term success of the business by tying earned amounts to three-year financial performance cycles, facilitating retention of key talent, and aligning incentives with our long-term strategic goals.

•Leadership Recruitment and Retention. Compensation is designed to be competitive within our industry and to retain top talent. Compensation programs are designed to recruit, motivate, retain, and reward NEOs for delivering operational and strategic performance over time.

The Compensation Committee of the Company’s board of directors (the “Compensation Committee”) intends to provide a balanced mix of short- and long-term compensation. When the Compensation Committee considers any component of the NEO’s compensation, the aggregate value and mix of all components are taken into consideration. The Compensation Committee believes that each element of compensation is important and that it is the appropriate combination of these components that enable us to appropriately compensate and retain executives.

Compensation Components

To support our compensation philosophy, our NEO compensation program for 2019 provided a mix of fixed and variable compensation components that based the majority of each executive’s compensation on the success of the Company’s operating performance as measured by the financial metrics of

120

bookings, revenue, adjusted earnings before interest, taxes, and amortization (EBITA), and free cash flow from continuing operations, and the executive’s individual performance relative to the Company’s business goals of execution of our portfolio, growth, and taking care of our people.

Compensation Components	Purpose	Description
Annual Base Salary	Provides competitive, fixed-rate cash compensation.	Base Salary is set at or around the median of our peers, with consideration given to level of responsibility, position held, job performance, years of experience in the position, and market value.
Annual Incentive Compensation	Designed to provide a cash incentive based on annual business performance aligned with our financial, strategic, and operational goals.	•2019 annual incentives were tied to financial metrics (75%) and individual performance objectives (25%). ◦Financial metrics were based on bookings (25%), revenue (25%), adjusted earnings before interest, taxes and amortization (25%), and free cash flow (25%).* ◦Individual performance objectives (25%) were aligned with 2019 strategic and operational objectives.

Long-Term Incentive (“LTI”) Compensation	Provides our NEOs with a significant personal stake in the long-term success of the business, aligns the incentive to support our long-term strategic goals, and facilitates the retention of key talent over the long-term.	•The LTI provides participants with an annual award target distributed over a three-year performance cycle, with earned awards paid on an annual basis. •The LTI awards earned in 2019 were based on participants’ vested target awards granted in 2017, 2018, and 2019. •The LTI is comprised of two components: Company performance (70%) and retention (30%). ◦Company performance component of the annual target is distributed equally over the three-year cycle and is based on bookings (60% weighting) and economic value added (40% weighting).* ◦Retention component requires continued employment for three years. •Entirely cash-based plan prior to the Company’s initial public offering.
Retirement Benefits	A 401(k) provides all eligible employees, including executive officers, with the ability to set aside compensation on a pre-tax or Roth basis and receive competitive matching contributions. Certain employees participate in a legacy frozen defined benefit pension plan from a prior acquisition.	•401(k) Plan provides a discretionary Company match contribution, which is immediately vested. •Benefit accruals under the legacy frozen defined benefit pension plan for eligible employees were frozen at the end of 2011.
Limited Executive Perquisites	Eligible executives participate in the Executive Allowance Program. This allowance program was designed to provide limited benefits to assist with costs associated with personal, physical, and fiscal fitness.	•In 2019, participating executives received an annual fixed amount, paid on a bi-weekly basis. •The allowance covered expenses associated with such needs as executive physical exams, life insurance, disability and/or liability insurance, tax preparation services, financial planning.

122

Double-Trigger Change in Control Benefits The Change in Control Agreement is intended to retain qualified executives, maintain a stable work environment, and provide economic security in the event of certain terminations of employment as a result of a change in control. •The Change in Control Agreements provide “double-trigger” severance if an executive’s employment is terminated by the Company without cause or by the executive for good reason within 24 months following a change in control.

*Certain of the Company performance metrics are non-GAAP measures, as discussed in more detail under “Components of Compensation Program” below.

THE COMPENSATION PROCESS

Role of the Compensation Committee

The board of directors has delegated its authority to the Compensation Committee for certain compensation related matters. The Compensation Committee approves and is actively engaged in the design and implementation of the Company’s executive compensation programs, with the support of the compensation consultant and Company management. In performing its duties, the Compensation Committee:

•Oversees the administration of the Company’s executive compensation program.

•Determines and approves the compensation levels for all NEOs annually.

123

•Receives advice from Willis Towers Watson, the Company’s compensation consultant.

•Reviews peer group and benchmarking data and other survey input from the compensation consultant.

•Evaluates the competitiveness of each executive officer’s total compensation package.

•Oversees and approves the cost and design of the Company’s retirement plans.

•Reviews and approves the individual and Company annual and long-term goals and objectives for the NEOs, evaluates the Company’s strategic, financial, and operational performance against those goals and objectives, and determines and approves all annual and long-term compensation earned by the NEOs based on this evaluation.

•Reviews competitiveness and business fit of overall executive compensation plans, philosophies, and policies.

Role of the Compensation Consultant

The Company retains Willis Towers Watson as its compensation consultant to provide advice on executive compensation matters. The role of the compensation consultant includes:

•Provides information on competitive market data in general executive compensation as it impacts NEOs.

•In consultation with management, develops peer group proxy data and provides survey data from likely sources of competition for executive talent to assess competitive levels and target positioning.

•Reviews and advises the Compensation Committee on executive compensation philosophy and programs, pay and performance alignment, and program design.

•Identifies market trends and practices and advises the Compensation Committee on program design implications.

During 2019, Willis Towers Watson performed the following specific services:

•Attended Compensation Committee meeting held in January for review and discussion of the compensation processes and to present the market benchmarking analysis.

•Provided regulatory education to the Compensation Committee.

•Provided information and advice relating to executive compensation matters.

Willis Towers Watson also provided communication services and consulting and broker services to the Company in 2019. In 2019, the Company paid fees to Willis Towers Watson for its services as a compensation consultant of approximately $34,500, for its communication services of approximately $182,500 and for its consulting and broker services of approximately $390,000.

124

Role of Management

The Company’s Chief Executive Officer1 evaluates the performance of other NEOs and makes recommendations to the Compensation Committee regarding base salary, annual compensation targets, and long-term cash incentive compensation targets for the NEOs other than himself. Other members of the Company’s management, including the Chief Financial Officer; Chief Operating Officer; General Counsel; and Senior Vice President, Human Resources, (1) makes recommendations to the Chief Executive Officer regarding annual and long-term incentive plan design and performance metrics, (2) provides NEO analysis in collaboration with the compensation consultant and (3) provides information and recommendations regarding board of director pay with guidance from the compensation consultant.

Use of Competitive Compensation Data

We demonstrate our commitment to aligning compensation with Company performance by strongly linking compensation to the strategic, financial and operational performance of the Company. The Company targets NEO total direct compensation at or around the median percentile of the peer group by component, with consideration given to level of responsibility, position held, job performance, years of experience in the position, internal pay equity, and market value. Realized compensation from other factors of wealth accumulation are not considered in setting current compensation levels. Our program provides for above-median pay for above-median performance and below-median pay for below-median performance. To the extent total compensation exceeds targeted levels, it is directly attributable to performance that increases Company value and exceeds measurable, clearly defined performance goals. Conversely, total compensation can be substantially less than target for performance that falls significantly short of pre-established targets.

The Compensation Committee analyzed competitive market data utilizing peer group and industry survey data when evaluating NEO compensation levels. The peer group is representative of competitors within similar markets and industries and with relative revenue size. Peer group performance is a key relative measure for the Company’s annual incentive plan and performance-based LTI metrics. The Compensation Committee, with guidance from Willis Towers Watson and management, used a 2019 peer group consisting of the following 16 companies:

COMPONENTS OF COMPENSATION PROGRAM

Annual Base Salary

The goal of our base salary is to provide a competitive, fixed rate of cash compensation. Accordingly, we pay each NEO a base salary that is set at or around the median of our peers, and take into consideration the position held, the executive’s career experience, the scope of the position’s responsibilities and the executive’s own performance. Base salaries are reviewed annually, and increases, when they occur, are driven primarily by changes in the market. Consequently for 2019, we adjusted the salaries for all of our NEOs. We believe that organizations perform well over the long term when they make an effort to pay salaries at or near the market median and create opportunities for executives to earn above-median compensation through annual and long-term incentives that are

126

awarded based on performance relative to challenging and clear performance goals. The base salary earned by each NEO was:

Name	Base Salary

	$

Annual Incentive Compensation

The NEOs were eligible to earn an annual cash incentive award under our Incentive Compensation Plan (the “ICP”) for performance in 2019. The ICP is designed to make a significant portion of each NEO’s total cash compensation contingent upon the successful achievement of certain annual corporate financial and individual goals and objectives. For that reason, 75% of the NEOs’ annual incentive target is tied to financial performance, while the remaining 25% is tied to significant individual goals and objectives. The incentive received is based on both Company and individual performance against specific, measurable goals established at the beginning of the year and approved by the Compensation Committee. For individual performance, the Chief Executive Officer assesses the other NEOs’ individual contributions, and the Compensation Committee assesses and approves the Chief Executive Officer’s contributions and approves the Chief Executive Officer’s assessment of each NEO’s contributions.

Targets for Annual Incentive

Each NEO’s target annual incentive, as a percentage of base salary, was determined during our annual compensation benchmarking process and is generally designed to provide total cash compensation at or around the market median and balances other considerations such as Company performance, complexity of the role, length of service, future expected contributions, and impact to the Company’s annual growth and profitability. Consistent with peer and market practice, the maximum incentive award that can be earned under the ICP is two times the target amount. For performance that falls significantly short of the pre-established target, there may be no payout.

Performance Metrics for Annual Incentive

For 2019, the annual incentive for each NEO was determined based on two categories of performance metrics: four equally weighted financial metrics totaling 75% of the award opportunity; and individual goals and objectives, both strategic and operational, weighted at 25% of the award opportunity. At the beginning of 2019, the Company performance objectives were approved by the Compensation Committee to align our annual operating plan, reflect the Company’s strategic plan, and to ensure challenging goal-setting. Individual goals and objectives were developed independently between the respective NEO and Chief Executive Officer. The individual goals for the Chief Executive Officer’s annual incentive were developed by the Chief Executive Officer and presented to the Compensation Committee for consideration and approval. All goals are tied to strategic business needs for the coming year and are pushed down through the organization to align all incentive pay participants with Company goals and objectives. The Compensation Committee determines the final payout by considering the NEOs’ achievements and contributions during the year as well as Company performance, market conditions and difficulty of achieving the goals.

127

2019 Financial and Individual Performance Targets and Achievement for Annual Incentive

Financial Performance Metric. Each financial performance metric is weighted equally at 25%, with the performance thresholds and payout ranges shown in the table below and no payout earned for performance below the minimum threshold:

The 2019 Company financial performance objectives are set forth in the table below:

Performance Metric(1)	Weighting	Minimum (in millions)	2019 Target (in millions)	Maximum ( in millions)
Bookings(2)	25%	$1,981.44	$2,201.6	$2,752.00
Revenue(3)	25%	$2,187.00	$2,430.0	$3,037.50
Adjusted EBITA(4)	25%	$183.24	$203.6	$254.50
Free Cash Flow(5)	25%	$112.50	$125.0	$156.25

________________

(1)Targets calculated in accordance with International Financial Reporting Standards (IFRS). The Company used IFRS as its principal method of accounting.

(2)“Bookings” is calculated as the total value of contract awards received from the U.S. government for which it has appropriated funds and legally obligated such funds to the Company through a contract or purchase order, plus the value of contract awards and orders received from customers other than the U.S. government.

(3)For purposes of the ICP, Revenue is calculated as the sales revenue results achieved during 2019 as reported in the Company’s audited financials.

(4)Adjusted EBITA is calculated as our net earnings before income taxes, amortization of acquired intangible assets, depreciation, restructuring costs, interest, transaction costs related to this offering, acquisition and divestiture related expenses, foreign exchange, non-service pension expenditures and other one-time non-operational events.

(5)“Free Cash Flow” is calculated as operating cash flow minus capital expenditures plus proceeds from sale of tangible/intangible assets and dividends received from joint ventures accounted for under equity method accounting treatment.

The ICP financial performance objectives were subject to adjustment by the Compensation Committee, as recommended by the Chief Executive Officer, for any of the following events: asset write-downs; significant litigation or claim judgments or settlements; the effect of changes in tax laws, accounting standards or principles, or other laws or regulatory rules affecting reporting results; any reorganization and restructuring programs; extraordinary nonrecurring items; acquisitions or divestitures; foreign exchange gains and losses; a change in the Company’s fiscal year; and any other nonrecurring events. The Chief Executive Officer with the approval of the Compensation Committee, had the discretion to determine that no award would be earned by a participant if the Company’s Adjusted EBITA for the year did not exceed 50% of the Adjusted EBITA target established for the 2019 ICP.

Individual Performance Objectives. The individual goals and objectives are specific, measurable goals, can be quantitative or more subjective, and are evaluated based on their relative importance to the strategic and operational performance, solid execution, and success of the Company. The Chief Executive Officer provides a goal rating from 0% to 200% for each of the other NEO’s individual goals and objectives, and the goal ratings are averaged to determine each NEO’s overall goal rating. The Compensation Committee is presented with each NEO’s achievement of their individual goals, and the overall goal rating for review and approval. For the Chief Executive Officer, the Compensation Committee reviews the individual goals and objectives performance, and approves an overall goal rating.

128

Earned Awards. The level at which each of the NEOs earned the award opportunity under the ICP was recommended by the Chief Executive Officer (for NEOs other than the Chief Executive Officer) and approved by the Compensation Committee, and determined by the Compensation Committee for the Chief Executive Officer.

The Chief Executive Officer, with Compensation Committee consent, has the ability to apply an additional factor to the ICP earned award for the other NEOs, referred to as a discretionary factor, which is an increase or decrease to an ICP earned award. The discretionary factor adjusts the ICP earned award under the ICP performance objectives (Company and individual) for an NEO when there is outstanding performance, or when an NEO has fallen short of expectations in the plan year. The Compensation Committee has the sole authority to apply a discretionary factor to the Chief Executive Officer's ICP earned award.

The final ICP earned award, determined based on Company and individual performance, and any discretionary factor, for each of the NEOs is approved by the Compensation Committee. In no event may the ICP final earned award exceed 200% of the NEO’s target award opportunity.

2019 Incentive Performance Achievement

Company Performance (75% of Incentive Opportunity). The Compensation Committee determined that the achieved ICP corporate performance objectives for 2019 were as follows, reflecting above-target achievement of bookings and revenue metrics, achievement of the EBITA metric slightly above the target level, and achievement of the target free cash flow metric:

Performance Objective	Weighting	Actual 2019 Performance (in millions)2	Earned Award (% of Target)
Bookings	25%	$2,923.2	200%
Revenue	25%	$2,729.3	148%
Adjusted EBITA(1)	25%	$207.2	108%
Free Cash Flow	25%	$125.5	100%

________________

(1)The Adjusted EBITA result does not include the AAC joint venture income. With AAC joint venture included, Adjusted EBITA result is $209.3 million.

(2)Actual performance was calculated in accordance with IFRS. The company used IFRS as its principal method of accounting.

Individual Performance (25% of Incentive Opportunity). The individual strategic and operational goals for each NEO were designed to reflect the significant individual performance expectations for the NEO and reward notable achievements that exceeded expectations. Each NEO is expected to contribute to the financial performance of the Company beyond that specifically recognized in the financial performance metrics listed in the table above. The following goals, results and contributions were taken into consideration by the Compensation Committee to assess the performance of each NEO and are reflected in the level at which the individual performance metric was achieved.

Long-Term Incentive

We historically have awarded cash-based long-term incentive opportunities to the NEOs under our 2014 Long-Term Incentive (“LTI”) Plan, rather than equity-based opportunities because we were privately held. The purpose of the LTI is to motivate participants by making a portion of their compensation contingent on the achievement of certain multi-year Company performance goals and a retention component to enable the Company to attract and retain key talent, and promote effective use of the Company’s resources to achieve expected and superior performance. LTI comprises more than 40% of each NEO’s target total direct compensation. This provides our executives with a significant personal stake in the long-term success of Leonardo DRS. As delegated by the board of directors, the LTI is administered by the Compensation Committee. Each NEO’s annual target and earned award recommendation are approved by the Compensation Committee.

Targets for Long-Term Incentive

The aggregate target opportunity for each NEO under the LTI Plan was established using competitive benchmarking at or around the market median and balances other considerations such as Company performance, complexity of the role, length of service, future expected contributions, and impact to long-term growth and profitability. We believe the LTI allows for the consideration of other factors in addition to the quantitative metrics that drive annual incentive payments. Earned awards provided under the LTI may range from 0% to 200% of the target award opportunity. The annual LTI target for the NEOs are shown in the table below.

Name LTI Target

Vesting Terms for Long-Term Incentive

The 2019 LTI target award was comprised of two components, a Company financial performance component designed to tie compensation opportunities to achievement of certain corporate performance goals over a three year performance cycle; and a retention component to encourage the retention of key employees. The two components combined provided a total compensation opportunity competitive with the businesses with which the Company competes.

130

Company Performance. The Company performance component comprised 70% of each NEO’s 2019 target LTI award, vesting in three equal annual installments over the period from 2019 through 2021. In order to be eligible for any portion of the Company performance component of the LTI award, the NEO must be actively employed by the Company and in good standing on the date of payment.

The Company performance metrics for the 2019 LTI Plan, comprising metrics for each of 2019, 2020 and 2021, were approved in March of 2019 by the Compensation Committee. Performance is measured based on bookings weighted at 60%, and economic value added (EVA) weighted at 40%, with the performance thresholds and payout ranges shown in the table below and no payout earned for performance below the minimum threshold:

“Bookings” has the same meaning as used for purposes of the ICP. See “Annual Incentive Compensation” above.

“Economic Value Added” or “EVA” is calculated as net operating profit after taxes (NOPAT) minus the Company’s average invested capital multiplied by the Company’s weighted average cost of capital. NOPAT is calculated as EBITA minus tax expenses.

Retention. The retention component comprised 30% of each NEO’s target LTI award and will be payable after the end of the three-year performance cycle. In order to be eligible for retention award, the NEO must be actively employed by the Company and in good standing on the date of payment.

Approval of Performance Achievement for the Long-Term Incentive

Earned award recommendations for each of the NEOs are approved by the Compensation Committee. The Compensation Committee has the authority to adjust the LTI performance objectives for any of the following events: asset write-downs; significant litigation or claim judgments or settlements; the effect of changes in tax laws, accounting standards or principles, or other laws or regulatory rules affecting reporting results; any reorganization and restructuring programs; extraordinary nonrecurring items; acquisitions or divestitures; foreign exchange gains and losses; a change in the Company’s fiscal year; and any other nonrecurring events. The LTI plan permits the Compensation Committee to exercise negative discretion to reduce or eliminate an award that would have been earned under the performance objectives as the Compensation Committee determines appropriate.

2019 Long-Term Incentive Performance Component Achievement (2017, 2018, 2019 Performance Awards)

Consistent with the long-term incentives awarded for 2019, each of the NEOs was granted long-term incentive awards in 2018 and 2017 under the LTI plan. A portion of the performance component for the

131

NEOs’ 2019, 2018, and 2017 awards vested based on the level at which 2019 performance metrics were achieved. The Company performance targets established for bookings and EVA for each performance cycle (2017, 2018 and 2019) and the achievements are shown in the table below:

LTI Award	Metric1	Weighting	Revised Target (in millions)2	Actual ( in millions)3	Achievement %	Financial Award Factor %4	Weighted Performance Award Factor5

2019 Long-Term Incentive Achievement for the Retention Component

The retention component, 30% of the LTI annual target, under the LTI Plan is payable after three-years subject to the NEO’s continued employment with the Company as of the LTI payment date.

The table below reflects the achievement of the two LTI components for the 2019 LTI Earned Award.

Benefits and Perquisites

The benefits provided by the Company are an important tool used to attract and retain executive talent. These benefits are designed to be competitive, cost-effective, and support the overall needs of our employees. The NEOs are eligible to participate in health and welfare benefits, retirement benefits, and executive perquisites.

Company-Sponsored Retirement Plans

Leonardo DRS 401(k) Plan. We sponsor the 401(k) Plan, a tax-qualified defined contribution plan, for our eligible employees, including the NEOs. Each NEO is eligible to make before-tax contributions to the 401(k) Plan, and after-tax contributions through a Roth 401(k) (or any combination of the foregoing), up to plan and tax law limits. The 401(k) Plan also provides participants with the opportunity to earn a Company match contribution. During 2019, the 401(k) Plan provided for a Company-matching contribution of 100% on contributions up to the first 5% of eligible pay for NEOs.

Defined-Benefit Retirement Plan. Certain employees participate in the Pension Plan for Employees of DRS Naval Power Systems, Inc., a Company-sponsored, tax-qualified, noncontributory defined-benefit plan (the “Pension Plan”). The Pension Plan was amended in October 2011 to freeze benefits for participants as of December 31, 2011. Benefits under the Pension Plan are accrued benefits calculated using the final average pay formula, with an early retirement option at age 55, and normal retirement at age 65. Final average monthly pay takes into account base salary and certain variable pay programs, but excludes non-recurring bonuses and executive incentive plans and any amount paid after December 31, 2011. Additional payment options may be available including a lump sum, period certain, and social security adjustment options if the participant retires early. Early retirement benefits, after age 55, are subject to a reduction schedule based on the participant’s age at commencement and credited service. This projected benefit is not subject to cost-of-living adjustments.

Health and Welfare Benefits

Our Chief Executive Officer is the beneficiary of an individual term life insurance policy. We pay the required premiums for individual term life insurance for the benefit of our Chief Executive Officer on an annual basis. The policy was effective October 17, 2019, and is for a ten-year period. All other NEOs, including our Chief Executive Officer, are provided Company-funded group term life coverage of two times their annual base salary up to a maximum amount of $500,000 with reductions starting at age 65. The life benefit under the term life coverage will reduce by 35% at the age of 65, and will reduce by 50% at the age of 70.

All of our current NEOs are eligible to participate in our employee benefit plans, including our medical, dental, vision, life, and accidental death and dismemberment insurance plans, in each case on the same

133

basis as all of our other employees. The senior leadership of the Company, including the NEOs, receive an enhanced short-term disability benefit of 70% of coverage with a weekly maximum of $3,500.00, and an enhanced long-term disability benefit of 66 2/3% of coverage with a monthly maximum of $15,000.00.

Pursuant to our vacation policy, on an annual basis we pay eligible employees, including each of the NEOs, for any accrued and unused vacation benefits in excess of 240 hours, up to a maximum of 40 hours of base pay.

Executive Perquisites

We provide our NEOs with an annual fixed perquisite allowance under the Executive Allowance Program that the Compensation Committee believes is reasonable yet competitive to attract and retain key talent. The Company provides perquisites to the NEOs for purposes of recruitment, retention and security and to ensure the personal, physical, and fiscal fitness of our executives to facilitate the transaction of business. The Company consulted with Willis Towers Watson regarding the market practice of our peers when considering the perquisite allowance.

The perquisite allowance provided to our NEOs was designed to be used at their discretion for such items as financial planning and tax preparation services, physical examinations, home security systems, personal liability and supplemental accidental death and dismemberment insurance, and the personal use of automobiles owned or leased by the employee. The executive allowance is paid to NEOs on a bi-weekly basis.

Severance and Change in Control Benefits

Incentive Awards

Termination under the ICP. Annual incentive awards earned under the ICP generally were only payable subject to the NEO’s continued employment through the date on which awards are paid; however the Compensation Committee has the discretion to pay a prorated earned award in the event of a NEO’s involuntary separation of employment for reasons other than cause after September 1 of a plan year, or due to death or disability.

Termination under the LTI. Long-term incentive awards are payable subject to the NEO’s continued employment through the date on which awards are paid. In the event of a NEO’s involuntary separation of employment for reasons other than cause after December 31 of a plan year, the Compensation Committee may, in its sole discretion, authorize an award payment subject to achievement of any performance conditions for the plan year or portion of the performance cycle of which the plan year is a part. If the NEO’s employment was terminated due to death or disability, then the Compensation Committee, in its sole discretion, may authorize a prorated award payment subject to achievement of any performance conditions.

Clawback Provision. The ICP and LTI include executive compensation recoupment, or “clawback,” provisions. The clawback would apply in the event that the Company subsequently discovers facts that, if known earlier, would have constituted grounds for termination of employment for “cause” (as defined in the ICP or LTI as applicable) prior to the payment of the earned award. Additionally, in the event of a restatement of the Company’s financial results (other than a restatement caused by a change in applicable accounting rules or interpretations), the result of which is that an earned award would have been lower if calculated based on the restated results, the Compensation Committee will review each earned award during the period in question. If the Compensation Committee determines that the restatement is the result of the negligence, misconduct, deception, non-disclosure, policy violation or fraud by a NEO, the Compensation Committee in its discretion may require repayment of all or a portion of the award.

Change In Control Benefits

The Company has entered into a Change in Control Agreement with each of the NEOs pursuant to the Leonardo DRS, Inc. Amended and Restated Executive Change in Control Plan as in effect as of September 2016. The Company believes these agreements are an important tool for recruiting talent, maintaining a stable work environment, and retaining highly qualified executives. In 2019, the Change in Control Agreement was entered into to protect the interests of the Company by including a “double-trigger” mechanism that results in a severance payout only when (a) change of control (as defined in the Change in Control Agreements) is consummated, and (b) the executive’s employment is terminated by the Company without cause or by the executive for good reason within 24 months following the change in control. The Compensation Committee periodically evaluates and reviews payment and benefit levels under the Change in Control Agreements against the practices of our peer group companies.

Other Considerations

Compensation and Risk Management

With the support of management and the compensation consultant, the Compensation Committee evaluates the Company’s overall risk profile relative to the incentive components of compensation. The use of long-term incentive awards as a significant portion of total direct compensation are structured to ensure management is focused on the long term and not incentivized to take excessive risk.

Tax Considerations

Code Section 162(m) limits tax deductions relating to executive compensation of certain executives of publicly held companies. For taxable years ended prior to this offering, the Company was not deemed to be publicly held for purposes of Code Section 162(m). Accordingly, these limitations were not applicable to the executive compensation program described above and were not taken into consideration in making compensation decisions. For future years, we expect to review and consider the deductibility of executive compensation under Internal Revenue Code Section 162(m), taking into account the changes to Code Section 162(m) effective for taxable years after 2017. However, in light of these changes, it is expected that we may pay compensation that is not deductible for federal income tax purposes when the board of directors (or a committee of the board of directors) believes that such payments are appropriate to attract, retain and incentivize executive talent.

(1)Benefits under the Pension Plan for Employees of DRS Naval Power Systems, Inc. were frozen effective as of December 31, 2011.

The Pension Plan for Employees of DRS Naval Power Systems, Inc.

Certain employees participate in the Pension Plan for Employees of DRS Naval Power Systems, Inc., a Company-sponsored, tax-qualified, noncontributory defined-benefit plan (the “Pension Plan”). The Pension Plan was amended in October 2011 to freeze benefits for participants as of December 31, 2011. Benefits under the Pension Plan are accrued benefits calculated using the final average pay formula, with an early retirement option at age 55, and normal retirement at age 65. Final average monthly pay takes into account base salary and certain variable pay programs, but excludes non-recurring bonuses and executive incentive plans and any amount paid after December 31, 2011. Additional payment options may be available including a lump sum, period certain, and social security adjustment options if the participant retires early. Early retirement benefits, after age 55, are subject to a reduction schedule based on the participant’s age at commencement and credited service. This projected benefit is not subject to cost-of-living adjustments.

POTENTIAL PAYMENTS UPON TERMINATION OR CHANGE IN CONTROL

As discussed under “Components of Compensation Program—Benefits and Perquisites—Severance and Change in Control Benefits,” NEOs may be entitled to certain amounts under the ICP and LTI on a termination of employment in certain limited circumstances, to the extent earned. Additionally, NEOs are eligible for certain “double trigger” severance benefits in the event of a qualifying termination of employment in connection with a change in control.

This section estimates the payments that would be received by our NEOs upon a termination of employment effective as of December 31, 2020. No payments or benefits would be payable to our NEOs solely as a result of a change in control of the Company.

Name Involuntary Termination without Cause or due to Death or Disability Termination without Cause or for Good Reason in connection with a Change in Control

PRINCIPAL AND SELLING STOCKHOLDERS

Prior to the completion of this offering, all the shares of our common stock have been owned by US Holding, a wholly owned subsidiary of Leonardo S.p.A. Immediately following the offering, US Holding will own approximately           % of our outstanding common stock, assuming no exercise by the underwriters of their option to purchase additional shares, and approximately          % of our common stock if the underwriters exercise their option to purchase additional shares in full.

The following table sets forth information as of          , 2021 with respect to the ownership of our common stock by:

•each person known to own beneficially more than five percent of our common stock, including the selling stockholder;

•each of our directors;

•each of our named executive officers; and

•all of our current executive officers and directors as a group.

The amounts and percentages of shares beneficially owned are reported on the basis of regulations of the SEC governing the determination of beneficial ownership of securities. Under SEC rules, a person is deemed to be a “beneficial owner” of a security if that person has or shares voting power or investment power, which includes the power to dispose of or to direct the disposition of such security. A person is also deemed to be a beneficial owner of any securities of which that person has a right to acquire beneficial ownership within 60 days. Securities that can be so acquired are deemed to be outstanding for purposes of computing such person’s ownership percentage, but not for purposes of computing any other person’s percentage. Under these rules, more than one person may be deemed to be a beneficial owner of the same securities, and a person may be deemed to be a beneficial owner of securities as to which such person has no economic interest.

Percentage computations are based on approximately          shares of our common stock outstanding as of          , 2021. The numbers of shares on the following table have not yet been adjusted to reflect our anticipated stock split prior to the completion of this offering.

Except as otherwise indicated in these footnotes, each of the beneficial owners listed has, to our knowledge, sole voting and investment power with respect to the indicated shares of common stock.

140

Unless otherwise set forth in the footnotes to the table, the address for each listed stockholder is c/o 2345 Crystal Drive, Suite 1000, Arlington, Virginia 22202.

CERTAIN RELATIONSHIPS AND RELATED PARTY TRANSACTIONS

Policies and Procedures for Related Person Transactions

Following the completion of this offering, our audit committee will have the primary responsibility for reviewing and approving or disapproving “related-party transactions,” which are transactions between us and related persons in which the aggregate amount involved exceeds or may be expected to exceed $120,000 and in which a related person has or may have a direct or indirect material interest. Upon completion of this offering, our policy regarding transactions between us and related persons will provide that a related person is defined as a director, executive officer, nominee for director or greater than 5% beneficial owner of our securities, in each case since the beginning of the most recently completed year, and any of their immediate family members. Our audit committee charter that will be in effect upon completion of this offering will provide that our audit committee will review and approve or disapprove any related-party transactions.

Relationship with Leonardo S.p.A. Following this Offering

We are, and until completion of this offering will remain, an indirect wholly owned subsidiary of Leonardo S.p.A. Following this offering, Leonardo S.p.A., through US Holding, will continue to own a majority of our outstanding common stock, and, as a result, Leonardo S.p.A. will continue to have significant control over our business and affairs and matters being presented for approval by our stockholders, in each case subject to the terms of our proxy agreement described below. See “Risk Factors—Risks Relating to Our Status as a Controlled Company and under the Proxy Agreement.” In addition, we expect that Leonardo S.p.A. will continue to consolidate our financial results in Leonardo S.p.A.’s consolidated financial statements.

Proxy Agreement

We have entered into a proxy agreement, dated as of October 26, 2017, with the proxy holders, Leonardo S.p.A., US Holding and the DoD. Following this offering we expect to enter into an amended and restated proxy agreement (as amended and restated, the “proxy agreement”) and the parties to the proxy agreement have entered into a commitment letter, dated as of     , 2020, as to the form and content of the amended and restated proxy agreement which allows us to operate as if the amended and restated proxy agreement were already in effect. The following description of the proxy agreement therefore reflects the terms of the proxy agreement as it will be amended and restated, in accordance with the commitment letter, following this offering. The material terms of the amended and restated proxy agreement and the commitment letter are discussed below and the form of the amended and restated proxy agreement and the commitment letter have been filed as exhibits to the registration statement of which this prospectus forms a part.

Following this offering, Leonardo S.p.A. will continue to own the entire share capital of our immediate parent, US Holding, which, in turn, will beneficially own approximately     % of the voting power of our outstanding common stock (or     % if the underwriters exercise their option to purchase additional shares in full). As a result, we are deemed to be under FOCI under the NISPOM, which establishes procedures and requirements for government contractors, such as our company, with regard to classified information. Furthermore, the Italian state beneficially owns approximately 30.2% of Leonardo S.p.A.’s voting power (through its ownership of approximately 30.2% of the outstanding ordinary shares of Leonardo S.p.A.). A company is considered to be operating under FOCI whenever a foreign interest has the power, direct or indirect, whether or not exercised, and whether or not exercisable, to direct or decide matters affecting the management or operations of that company in a manner that may result in unauthorized access to classified information, may adversely affect the performance of classified contracts, or may undermine U.S. security or export controls. In order to be permitted to maintain our security clearances and our

142

access to classified data and to perform or bid on classified programs, we are required to mitigate FOCI, which we have done by entering into the proxy agreement. Among other things, the proxy agreement:

•provides that the shares of our common stock owned directly or indirectly by Leonardo S.p.A. are voted through proxy holders, who must be independent from current and prior affiliation with Leonardo S.p.A. and its subsidiaries (including US Holding and us) (subject to limited exceptions discussed below) and must maintain adequate security clearance;

•provides that the proxy holders are appointed by our immediate parent US Holding (in consultation with Leonardo S.p.A.), but the appointment is subject to approval of the DCSA, an agency of the DoD, and that the proxy holders must be members of our board of directors;

•restricts our ability to share facilities and personnel with and receive certain services from Leonardo S.p.A. or its other subsidiaries;

•requires us to maintain a government security committee of our board of directors; and

•regulates meetings, visits and communications that are not deemed to be routine business visits between us and Leonardo S.p.A. or its other subsidiaries.

The proxy agreement restricts the ability of Leonardo S.p.A. and US Holding to control our operations, as described further below. The proxy agreement will automatically terminate, among other reasons, if US Holding holds less than 50% of our outstanding shares of common stock and the DCSA determines that FOCI mitigation is no longer necessary. The proxy agreement has been filed as an exhibit to the registration statement of which this prospectus forms a part.

Proxy Holders

The proxy agreement requires the appointment of five proxy holders, who must be independent from current and prior affiliation with Leonardo S.p.A. and its subsidiaries (including US Holding and us), other than prior service as a proxy holder or as an outside director of us or a proxy agreement affiliate (as defined below), and maintain adequate security clearance, to vote the shares of our common stock owned directly or indirectly by Leonardo S.p.A. Proxy holders are appointed by US Holding after reasonable consultation with Leonardo S.p.A. and approval by the DCSA and serve for staggered three-year terms. During their terms, proxy holders may only be removed (i) for acts in violation of the proxy agreement, including the inability to protect the legitimate economic interest of US Holding, upon petition by US Holding to DCSA which may be granted or denied by DCSA in its sole discretion or (ii) for gross negligence or willful misconduct. Upon expiration of a proxy holder’s term, or the death, resignation, removal or inability to act of any proxy holder, the proxy holder may be reappointed or replaced by US Holding after consultation with Leonardo S.p.A. and approval by DCSA. Until a successor proxy holder accepts appointment, the remaining proxy holders may exercise all of the rights, powers and privileges of the proxy holders and if no proxy holders remain, the chairman of our board shall be automatically vested with all rights, powers, authorities and immunities of the proxy holders for an interim period until a new proxy holder is appointed by US Holding and approved by DCSA. The current proxy holders and the commencement and expiration of their terms are as set forth in the table below.

Proxy Holder	Term Commencement	Term Expiration
David W. Carey	January 1, 2018	December 31, 2022
Kenneth J. Krieg	January 1, 2018	December 31, 2021
Peter A. Marino	January 1, 2018	December 31, 2022
Philip A. Odeen	January 1, 2018	June 30, 2021
Frances F. Townsend	January 1, 2018	December 31, 2021

The proxy agreement confers on the proxy holders the right to vote US Holding’s shares of our common stock in the same manner and to the same extent as if they were the absolute owners of such

143

shares in their own right. All actions of the proxy holders with respect to US Holding’s shares of our common stock require a majority vote of the proxy holders. Each proxy holder is entitled to one vote. In exercising their power as proxy holders and fulfilling their duties as members of our board, the proxy holders are directed to seek to protect the legitimate economic interests of our shareholders and to act in a manner consistent with their fiduciary duties.

The proxy holders are permitted to vote for or consent to the following matters in their sole and absolute discretion, without consultation with US Holding or Leonardo S.p.A.:

•the election of additional directors who are not proxy holders, and who are proposed by US Holding after reasonable consultation with the nominating and corporate governance committee of our board;

•any changes or amendments to our certificate of incorporation or bylaws involving matters other than those described below;

•the sale or disposal of our property, assets or business other than as described below;

•our incurrence of debt or any pledge, mortgage or encumbrance of any of our assets other than as described below;

•any action necessary to effect the offering other than as described below;

•any action with respect to the foregoing, or any other matter affecting us and not specifically described below that US Holding might lawfully exercise.

The proxy holders may only vote for or consent to the following matters with the express written approval of US Holding:

•the sale or disposition of any of our subsidiaries, property, assets or business or those of our subsidiaries or the purchase by us or our subsidiaries of any business, properties, assets or entities, other than in the ordinary course of business, in any individual transaction where our investment (based on our share of the enterprise value) exceeds two percent (2%) of our revenues for the immediately preceding year or where our investment, in the aggregate, for all such sales or dispositions in a calendar year, exceeds an amount equal to five percent (5%) of our revenues for the immediately preceding year;

•the incurrence of debt or pledge, mortgage, lease or other encumbrance of our assets of those of our subsidiaries in connection with the incurrence of debt, if such incurrence would cause the aggregate outstanding principal amount of all debt of us and our subsidiaries to exceed a target leverage ratio set forth in our then-current operating plan, excluding current debt incurred for purposes of funding day-to-day working capital requirements in the ordinary course of business;

•any merger, consolidation, reorganization or dissolution of us of any of our subsidiaries except as permitted above and excluding transactions solely among our wholly owned subsidiaries; and

•the filing or making of any petition by us or our subsidiaries under the federal bankruptcy laws or any similar law or statute of any state or any foreign country.

In addition, the proxy holders may only vote to declare or suspend dividends after prior consultation with US Holding.

We and US Holding are required to jointly and severally indemnify and hold each proxy holder harmless from any and all claims arising from or in any way connected to his or her performance as a proxy holder except for his or her own individual gross negligence or willful misconduct.

144

Board of Directors

The proxy agreement requires that all five proxy holders serve as members of our board. Additionally, our board must elect a chair and, if the chair is not one of the proxy holders, our board must elect a lead outside director from among the proxy holders. Under the terms of the proxy agreement, the proxy holders shall, in their sole discretion and in their capacity as members of the nominating and corporate governance committee of our board, nominate four additional individuals who are not proxy holders, selected from candidates proposed by US Holding, in consultation with the nominating and corporate governance committee, as candidates for election to our board (the “non-proxy holder director nominees”). The non-proxy holder director nominees shall include (i) our chief executive officer and (ii) three additional individuals. If any non-proxy holder director nominee has a prior or existing contractual, financial or employment relationship with Leonardo S.p.A., such that they would not be an “independent director”, DCSA must approve their selection.

The nominating and corporate governance committee of our board, which will be comprised solely of proxy holders, will nominate the proxy holders for election as directors at any meeting of our stockholders at which directors are to be elected. At any such meeting, the proxy holders will vote on behalf of US Holding to elect the then-current proxy holders and the non-proxy holder director nominees to serve on our board for the succeeding year. The proxy holders may remove any non-proxy holder director nominee from our board by majority vote and after consultation with US Holding.

The proxy agreement requires our board to establish the GSC, consisting of all proxy holders, our chief executive officer, our general counsel, our CFSO and our TCO, to the extent that such officers have adequate security clearances. The role of the GSC is to ensure that we maintain policies and procedures, including a technology control plan, to safeguard classified information in our possession and to ensure that we comply with the proxy agreement, the ITAR, the EAR, and the NISPOM. The proxy agreement also requires that the audit committee of our board appoint an independent auditor to conduct an annual audit of our books and records which may be the same independent auditor used by Leonardo S.p.A. or US Holding unless the GSC concludes that measures are not reasonably available to ensure that performance of the audit by such auditor complies with the proxy agreement.

Facilities, Personnel and Services

The proxy agreement restricts our ability to share facilities and personnel with and receive certain services from (i) Leonardo S.p.A., (ii) each entity that, to our knowledge, Leonardo S.p.A. directly or indirectly controls, is directly or indirectly controlled by (other than DRS itself and our subsidiaries), or is directly under common control with, except for any entity operating under an effective DCSA FOCI mitigation agreement (each of (i) and (ii), a “proxy agreement affiliate”) or (iii) any director, officer, employee, beneficial owner of greater than 5% of a class of equity securities (as determined by voting or investment control over the securities), agent or other representative of a proxy agreement affiliate (together with the proxy agreement affiliates, the “proxy agreement affiliated group”).

Our officers may only serve as officers of any of the proxy agreement affiliated group and vice versa with the approval of the DCSA and the GSC. DRS may only collocate facilities and personnel with the proxy agreement affiliated group with the prior written approval of the DCSA pursuant to the submission by DRS of a facility location plan describing the location of the relevant facilities and which may include, at the DCSA’s request, information such as maps and floor plans of such facilities. Furthermore, DRS and the proxy agreement affiliated group may only engage in specified “affiliated operations” (as described below) pursuant to an AOP, setting out policies and procedures regarding services provided to, provided by, or exchanged between DRS and the proxy agreement affiliated group, and approved by the DCSA.

Any AOP must, at a minimum, require the GSC to notify the DCSA of any proposed category of affiliated operations and obtain DCSA approval prior to accepting or providing any associated affiliated operations, contain procedures for ensuring that any such services do not circumvent the requirements of the proxy agreement and require the GSC to provide the DCSA with an annual written certification that it

145

is effectively monitoring any affiliated operations and that such affiliated operations do not allow the proxy agreement affiliated group to exercise prohibited control or influence with respect to the management or business of DRS.

Affiliated operations include (i) sharing of employees between DRS and the proxy agreement affiliated group, (ii) receipt by both DRS and the proxy agreement affiliated group of third party professional services such as accounting, legal, tax, information technology or business consulting from the same service provider and (iii) the provision of products or services between DRS and the proxy agreement affiliated group, where the provision of such products or services could result in the potential for operational leverage by the proxy agreement affiliated group over DRS. See “—Affiliated Operations Plan (AOP) Services Agreements” below. Sharing of third-party services between DRS and the proxy agreement affiliated group may be approved by the majority of the GSC but such approval is subject to DCSA review and the DCSA may require the GSC to rescind any such approval. Sharing of services and products between DRS and the proxy agreement affiliated group pursuant to contracts and subcontracts, joint research, development, marketing or other type of teaming arrangement entered in connection with a commercial pursuit or joint business venture may be approved by the majority of the proxy holders and must be disclosed to the DCSA.

If DRS expects to use technology products or services of the proxy agreement affiliated group in connection with classified contracts, DRS must notify each applicable government contracting activity and provide the GSC with an annual report regarding such the notifications.

Meetings, Visits and Communications

The proxy agreement regulates meetings, visits and other communications between us and the proxy agreement affiliated group. Representatives of Leonardo S.p.A. and US Holding are required to be invited to meetings of the proxy holders but the agenda and minutes for such meetings must be provided to the DCSA for its review. Classified and controlled unclassified information may only be disclosed to Leonardo S.p.A. and its subsidiaries (including US Holding) as specifically authorized by applicable law or regulation.

All proposed visits (which may include teleconferences and videoconferences), other than routine business visits, between us and the proxy agreement affiliated group must be approved in advance by a proxy holder. Routine business visits are those that (i) are made by persons other than key management personnel, (ii) do not involve the transfer or receipt of classified information, (iii) either do not involve export-controlled information, or involve the approved transfer of export-controlled information under a proper license or authorization, (iv) do not relate to activities bearing upon our performance of classified contracts, and (v) pertain only to the commercial aspects of our business. Routine business visits may include visits for the purpose of discussion of financial performance and securities law compliance, arm’s-length business, U.S. government export control compliance and approved affiliated operations. As long as our DCSA security rating is “satisfactory” or above, routine business visits may be approved by the CFSO, rather than a proxy holder, and all such visits may be approved in advance for a period of up to 180 days. Strictly social visits between our personnel and the proxy agreement affiliate group are not prohibited but written reports of such visits must be submitted to the CFSO for review by the proxy holders. The GSC must maintain documentation related to all meetings, visitations and communications, together with appropriate approvals or disapprovals and reports, for review by the DCSA.

Compliance and Termination

The proxy holders are required to meet as necessary to satisfy their responsibilities under the proxy agreement and our board must meet at least four times per year in addition to any separate meetings of the proxy holders. Additionally, representatives of the DCSA, the proxy holders, other members of the GSC and certain other officers of DRS, Leonardo S.p.A. and US Holding are required to meet annually to review the purpose and effectiveness of the proxy agreement. The president of DRS and the chairman of the GSC are required to submit an annual report to the DCSA on the implementation of and compliance

146

with the proxy agreement, accompanied by a certificate from our corporate secretary certifying that each of the representations and warranties in the proxy agreement remain true and correct on the date of such report or providing updates as applicable. Under the proxy agreement, the DoD may impose any additional security safeguards that it believes necessary to adequately safeguard classified and controlled unclassified information.

In the event of a material breach of the proxy agreement, the DoD may (i) novate our classified contracts to a company not under FOCI at our expense, (ii) terminate our classified contracts and deny us new classified contracts, (iii) revoke our facility security clearance and/or (iv) suspend or debar us from participation in all U.S. government contracts.

The proxy agreement will expire by its terms five years from its effective date. Prior to that date, DCSA may terminate the proxy agreement if it deems the proxy agreement no longer necessary in order to maintain our facility security clearance or if our facility security clearance is no longer necessary, if there has been a breach of the proxy agreement that requires its termination or if the DCSA determines that terminating is necessary for national security or, in the DCSA’s sole discretion, upon petition by us or US Holding. Additionally, the proxy agreement will be automatically terminated upon the sale of our business or all of US Holding’s interest in us to a person or entity not controlled by Leonardo S.p.A. or if US Holding holds less than 50% of our outstanding shares of common stock and the DCSA determines that FOCI mitigation is no longer necessary.

Cooperation Agreement

We intend to enter into a cooperation agreement with Leonardo S.p.A. and US Holding upon the completion of this offering (the “cooperation agreement”). The cooperation agreement will address rights that Leonardo S.p.A. and US Holding will have with respect to our business and financial information and financial accounting matters. The form of the cooperation agreement has been filed as an exhibit to the registration statement of which this prospectus forms a part and the discussion of the cooperation agreement in this prospectus is subject to and qualified in its entirety by reference to the form of cooperation agreement.

The cooperation agreement will require us, as long as Leonardo S.p.A. is required under IFRS to consolidate our financial results in the consolidated financial statements of Leonardo S.p.A., to continue to provide Leonardo S.p.A. with (A) information and data relating to our and our subsidiaries’ business and financial results and (B) reasonable access to our personnel, data and systems, in each case in the same manner as we do immediately prior to this offering as reasonably necessary for the preparation of the consolidated financial statements and related public disclosures of Leonardo S.p.A., in each case subject to the terms of the proxy agreement. In addition, during this period, we will be required to maintain accounting principles, systems and reporting formats that are consistent with Leonardo S.p.A.’s financial accounting practices in effect at the time of completion of this offering, and in good faith to consider any changes to such principles, systems or reporting formats requested by Leonardo S.p.A. to enable Leonardo S.p.A. to prepare its consolidated financial statements and related public disclosures. Furthermore, the cooperation agreement will require us during this time to maintain appropriate disclosure controls and internal controls.

Following the time at which the provisions of the immediately preceding paragraph cease to apply, and until the later of Leonardo S.p.A. being no longer required under IFRS (x) to account in its financial statements for its holdings in us under the equity method of accounting or (y) to consolidate our financial results with its financial results, unless Leonardo S.p.A. shall earlier provide written notice to us that it is opting out of these provisions, we will, subject to appropriate protections for our confidential or proprietary information, be obligated to provide Leonardo S.p.A. with (i) information and data relating to our and our subsidiaries’ business and financial results and (ii) access to our personnel, data and systems, in each case to the extent that such information, data or access is reasonably necessary for Leonardo S.p.A. to

147

meet its legal, financial or regulatory obligations or requirements and subject to the terms of the proxy agreement.

The cooperation agreement will provide that, until the date on which Leonardo S.p.A. is no longer required under IFRS to account in its financial statements for its holdings in us under the equity method of accounting, Leonardo S.p.A. will have certain consent, access and cooperation rights with respect to the independent public registered accounting firm responsible for the audit of our financial statements and access and cooperation rights with respect to our internal audit function.

The cooperation agreement will also provide that, until the later of the first date on which (1) the Proxy Agreement or a similar agreement with the DoD is no longer in effect, and (2) Leonardo S.p.A. is no longer required under IFRS (x) to account in its financial statements for its holdings in us under the equity method of accounting nor (y) to consolidate our financial statements with its financial results (such date, the “threshold date”), we shall consult and coordinate with Leonardo S.p.A. with respect to public disclosures and filings, including in connection with our quarterly and annual financial results. Among other requirements, we will, to the extent practicable and subject to appropriate confidentiality obligations, provide Leonardo S.p.A. with a copy of any public release at least one business day prior to publication and consider in good faith any comments provided by Leonardo S.p.A. We will have similar rights with respect to any public release by Leonardo S.p.A. that includes information with respect to us. In addition, we and Leonardo S.p.A. will have mutual rights with respect to any information and access each may require in connection with regulatory or supervisory reporting obligations or inquiries.

US Holding Consent Rights

Under the cooperation agreement, US Holding’s consent will be required for us and our subsidiaries to take certain actions, including the following:

•creation or issuance of any class or series of our capital stock (including designation of any preferred stock) or acquisition of any capital stock (including stock buy-backs, redemptions or other reductions of capital), or securities convertible into or exchangeable or exercisable for capital stock or equity-linked securities by us or any of our subsidiaries, except (i) issuances of equity awards to directors or employees pursuant to an equity compensation plan approved by our board of directors; (ii) issuances or acquisitions of capital stock by any wholly-owned subsidiaries (which remains wholly-owned after the issuance or acquisition); and (iii) issuances or acquisitions of capital stock that our board of directors determines are necessary to maintain compliance with covenants contained in any debt instrument;

•amendment (or approval or recommendation of any amendment) to our certificate of incorporation or by-laws that adversely affects the rights of US Holding or Leonardo S.p.A.;

•listing or delisting of any of our or any of our subsidiaries’ voting equity securities on a securities exchange;

•any material change in our accounting policy, including any change our fiscal year, and any termination or change of our external auditor; and

•pledge, mortgage, lease or otherwise encumber our assets or assets of our subsidiaries in connection with any debt if, after such pledge, mortgage, lease or other encumbrance, the aggregate outstanding principal amount of secured debt would exceed the aggregate outstanding principal amount of secured debt as of the date of the cooperation agreement, subject to certain exceptions.

Certain of US Holding’s rights under the proxy agreement, as described under “—Proxy Agreement—Proxy Holders,” will also apply under the cooperation agreement so long as it is in effect.

148

Term

The cooperation agreement will terminate on the date that is five years following the threshold date, except for certain provisions including those relating to confidentiality and dispute resolution.

Registration Rights Agreement

We will enter into a registration rights agreement (the “registration rights agreement”) with Leonardo S.p.A. and US Holding upon the completion of this offering, pursuant to which Leonardo S.p.A. will be able to require us, beginning     after this offering, to file one or more registration statements with the SEC covering the public resale of shares of our common stock beneficially owned by Leonardo S.p.A. Leonardo S.p.A. may transfer all or any portion of its rights under the registration rights agreement to a transferee of shares of our common stock constituting not less than     % of our outstanding common stock. The rights of Leonardo S.p.A. and its permitted transferees under the registration rights agreement will remain in effect with respect to all shares of our common stock covered by such agreement until such securities (a) are sold in a private transaction in which the transferor’s rights under the registration rights agreement are not assigned to the transferee, (b) are sold pursuant to an effective registration statement, (c) may be sold pursuant to Rule 144 without volume or manner of sale restrictions or (d) shall have ceased to be outstanding. The sale of shares pursuant to the Registration Rights Agreement, or the perception that sales will be made, could adversely affect the price of our common stock after this offering because a great supply of shares would be, or would be perceived to be, available for sale in the public market. The form of the registration rights agreement has been filed as an exhibit to the registration statement of which this prospectus forms a part and the discussion of the registration rights agreement in this prospectus is subject to and qualified in its entirety by reference to the form of registration rights agreement.

Demand Registration

Leonardo S.p.A. will be able to request registration under the Securities Act of all or any portion of our shares covered by the agreement, and we will be obligated, subject to limited exceptions, to register such shares as requested by Leonardo S.p.A. Leonardo S.p.A. will be able to request that we complete demand registrations and underwritten offerings during the term of the registration rights agreement subject to limitations on, among other things, minimum offering size. Subject to certain exceptions, we may defer the filing of a registration statement after a demand request has been made if, at the time of such request, our board determines that any pending or imminent event would require disclosure of material, non-public information in the registration statement for such registration statement not to be materially misleading and would not otherwise be required to be publicly disclosed by us. We will not be obligated to effect more than one demand registration in any period.

Shelf Registration

At any time after the date that is one year following the date of the registration rights agreement or, if sooner, once we become eligible to use a registration statement on Form S‑3, we will be obligated, upon request by Leonardo S.p.A. to file a shelf registration statement to register all or any portion of our shares covered by the registration rights agreement, and we will be obligated, subject to limited exceptions, to register such shares as requested by Leonardo S.p.A. Leonardo S.p.A. may, at any time and from time to time, request that we complete an unlimited number of shelf take-downs; provided, that no request shall be made within of the previous request.

Piggy-Back Registration

If at any time we intend to file on our behalf or on behalf of any of our other security holders a registration statement in connection with a public offering of any of our securities on a form and in a manner that would permit the registration for offer and sale of our common stock held by Leonardo S.p.A., Leonardo S.p.A. will have the right to include its shares of our common stock in that offering. Leonardo S.p.A.’s ability to participate in any such offering will be subject to market “cut-back” exceptions.

149

Registration Procedures; Expenses

Leonardo S.p.A. will be responsible for all registration expenses, including expenses incurred by us, in connection with the registration, offer and sale of securities under the registration rights agreement by Leonardo S.p.A.

The registration rights agreement will set forth customary registration procedures, including an agreement by us to make our management available for road show presentations in connection with any underwritten offerings. We will also agree to indemnify Leonardo S.p.A., US Holding and their permitted transferees with respect to liabilities resulting from any material untrue statements or omissions in any registration statement used in any registration or contribute to liabilities in respect thereof, other than untrue statements or omissions resulting from information furnished to us expressly for use in such registration statement by Leonardo S.p.A., US Holding or any permitted transferee. The registration rights agreement will not include any maximum cash penalties or any additional penalties resulting from delays in registering our common stock.

Tax Allocation Agreement

We and US Holding have entered into a tax allocation agreement (the “tax allocation agreement”), dated as of November 16, 2020, with members of an affiliated group (the “affiliated group”), as defined in Section 1504(a) of the Tax Code, members of one or more consolidated, combined, unitary or similar state tax groups (the “state members”) and additional parties who are part of an “expanded affiliated group” for certain tax purposes, prior to this offering. The agreement provides for the method of computing and allocating the consolidated U.S. federal tax liability of the affiliated group among its members and of allocating any state group tax liabilities among the state members for the taxable year ending December 31, 2020 and each subsequent year in which the parties are members of a group (whether federal or state). The tax allocation agreement also provides for reimbursement of US Holding and/or DRS for payment of such tax liabilities, for compensation of any member for use of its “net operating loss” or “tax credits” in arriving at such tax liabilities and the allocation and payment of any refund arising from a carryback of net operating losses or tax credits from subsequent taxable years. Under the tax allocation agreement, the parties have agreed to calculate and allocate their respective tax liabilities and other tax attributes for taxable years beginning with the first consolidated taxable year that included DRS (i.e., the taxable year ended March 31, 2009) as if the tax allocation agreement was then in effect.

The tax allocation agreement also allocates governance and decision-making rights, obligations and responsibilities in respect of the tax matters governed by the agreement including preparation and filing of covered returns, audits of covered returns and ensuring that payments and reimbursements in respect of covered returns are timely made. The tax allocation agreement provides for administration of the agreement and any related tax matters by us, in our reasonable discretion, with respect to any group to which we belong in any taxable year in which we are an affiliated group member or state member. For any taxable year in which we are not an affiliated group member or a state member, as applicable, US Holding will appoint an administrator. The tax allocation agreement will require the parties, including those who do not file consolidated, combined, unitary or similar tax returns with the other parties but whose operations may impact such returns filed by the other parties, to reasonably cooperate with US Holding and the administrator in carrying out the provisions of the agreement, including providing the administrator access to their books and records and other relevant information. The tax allocation agreement also requires the parties to cooperate in good faith, taking into account each relevant member’s tax consequences, in respect of certain specified matters as well as any other tax-related decision or matter the administrator determines, in its reasonable discretion, with the consent of US Holding where appropriate.

The tax allocation agreement is effective as of the first day of the consolidated return year beginning October 14, 2008 and will terminate upon the written agreement of the parties. The tax allocation agreement has been filed as an exhibit to the registration statement of which this prospectus forms a part

150

and the discussion of the tax allocation agreement in this prospectus is subject to and qualified in its entirety by reference to the tax allocation agreement.

To the extent that the issuance of shares of our common stock in this offering results in DRS no longer being included as a consolidated member of the U.S. federal and state returns of US Holding, we will be required to file standalone tax returns as of the date of the deconsolidation. Pursuant to the tax allocation agreement, we will generally retain our historic tax assets and will be able to offset future taxable income against these attributes. Accordingly, we do not anticipate any significant tax consequences as a result of exiting the US Holding consolidated tax group.

Trademark License Agreement

We will enter into a trademark license agreement (the “trademark license agreement”) with Leonardo S.p.A. prior to this offering pursuant to which Leonardo S.p.A. will grant us, subject to certain limitations, a limited, non-exclusive, non-transferable, non-sublicensable license to use certain trademarks (the “licensed marks”), including the name “Leonardo.” The Trademark License Agreement will remain in effect until it is terminated by Leonardo S.p.A.’s and our mutual agreement, or upon the occurrence of certain conditions, including Leonardo S.p.A.’s right to terminate should it no longer directly or indirectly own or control more than a specified percentage of our voting capital stock.

After the term of the trademark license agreement, we will be able to continue to use the licensed marks for a transition period (the “transition period”) of     months (which period is subject to an extension, capped at a total of     months (we can request an extension of such period), for any licensed mark for which we cannot obtain government approvals), but we will be required to use reasonable best efforts to transition to other trademarks.

The form of the trademark license agreement has been filed as an exhibit to the registration statement of which this prospectus forms a part and the discussion of the trademark license agreement in this prospectus is subject to and qualified in its entirety by reference to the form of trademark license agreement.

Affiliated Operations Plan (AOP) Services Agreements

Although we operate largely independently from Leonardo S.p.A., and the proxy agreement contains limitations on services that we may provide to and receive from Leonardo S.p.A. and its affiliates, we, Leonardo S.p.A. and Leonardo S.p.A.’s subsidiaries each provide certain services to the one another, share certain services and rely on certain third-party service providers to provide services pursuant to shared services contracts, subject to the terms of the proxy agreement and in accordance with our AOP, approved by the DCSA. Leonardo S.p.A. and its subsidiaries rely on certain contracts to which we are party for the provision of services that are important to Leonardo S.p.A.’s business. Likewise, we rely on certain contracts for the provision of certain services to which Leonardo S.p.A. or its subsidiaries are a party. For so long as we are required to comply with the AOP approval requirement for certain services within our proxy agreement affiliated group (see “—Proxy Agreement—Facilities, Personnel and Services” above), the proxy agreement will govern our continued provision or procurement of certain services among us, Leonardo S.p.A. and its subsidiaries and third-party service providers. The proxy agreement, including the AOP approval requirement, is expected to remain in place until such time as FOCI mitigation is no longer legally required.

Our AOP currently governs the following types of arrangements:

•services Leonardo S.p.A. or its subsidiaries (excluding us) receive pursuant to a contract with a third-party service provider, which Leonardo S.p.A. or its subsidiaries then provide to us on a pass-through basis;

•services we receive pursuant to a contract with a third-party service provider, which we then provide to Leonardo S.p.A. or its subsidiaries (excluding us) on a pass-through basis;

151

•certain services we receive directly from Leonardo S.p.A. or its subsidiaries (excluding us); and

•certain services we provide directly to Leonardo S.p.A. or its subsidiaries (excluding us).

Specifically, we are currently authorized to provide support services to Leonardo S.p.A. in the following functional areas:

•Compliance and Training

•Finance, Tax and Accounting

•Legal

•Marketing and Communications

•Procurement and Supply Chain

•Security

•Trade

The fees for each of the services to be provided under the AOP are mutually agreed upon as part of the negotiation of the services agreement and may vary on the basis of usage and other factors. Although we seek to implement commercially reasonable terms (including fees for the services provided) that could have been negotiated with an independent third party, the terms of such agreement may later prove to be more or less favorable than arrangements we could make to provide these services internally or to obtain them from unaffiliated service providers in the future.

Transactions with Leonardo S.p.A. Affiliates

As an indirect wholly owned subsidiary of Leonardo S.p.A., historically, we have entered into various transactions with Leonardo S.p.A. and its subsidiaries in the normal course of business. The transactions described below are between us and affiliates of Leonardo S.p.A. that are not also subsidiaries of DRS.

Sales

We have related-party sales with Leonardo S.p.A. and its other affiliates that occur in the regular course of business. Related-party sales for these transactions are included in revenues and were $16 million and $20 million for the years ended December 31, 2019 and 2018, respectively. We recognized related-party receivables and payables of $2 million and $10 million, respectively, for these transactions as of December 31, 2019.

Financing Arrangements

Term Loans

In January 2009, we entered into a credit agreement with Finmeccanica S.p.A. (now known as Leonardo S.p.A.) in the amount of $2 billion (the “Credit Agreement”). The Credit Agreement was subsequently assigned to US Holding and has a maturity of November 30, 2022.

The Credit Agreement provides for a term loan bearing interest at a rate of 7.5%, with interest payments due semi-annually on June 20 and December 20 in each year (the “7.5% Term Loan”). The outstanding balance of the 7.5% Term Loan at December 31, 2019 was $439 million.

In June 2017, we entered into an unsecured term loan with US Holding in the principal amount of $137.5 million, the proceeds of which were used to finance the acquisition of Daylight Solutions, Inc. (the “Daylight Term Loan”). The Daylight Term Loan had an outstanding balance of $113 million at December

152

31, 2019. The Daylight Term Loan matures on October 15, 2024. The Daylight Term Loan has an interest rate of 5.0%, with interest payments due semi-annually on April 15 and October 15.

During April 2018, we were advanced an additional $50 million by US Holding under a separate term loan. This loan bears interest at 4.0% and had an initial maturity date of December 31, 2018, which was extended until December 31, 2021. The outstanding balance of the 4.0% short-term facility at December 31, 2019 was $50 million, which approximates the fair value.

Credit Facilities

The Credit Agreement provides for a revolving credit facility available for our working capital needs (the “Revolving Credit Facility”). As of December 31, 2019, the Revolving Credit Facility had a credit limit of $350 million and an interest rate of LIBOR plus 3.5%. On April 15, 2020, the Company received US Holding’s consent to increase the Revolving Credit Facility by $100 million to $450 million. There is a commitment fee of 0.25% applied to the unused balance of the Revolving Credit Facility and there are no compensating balance requirements. The outstanding balance on the Revolving Credit Facility was $350 million as of November 30, 2020.

We also maintain uncommitted working capital credit facilities with certain financial institutions in the aggregate of $65 million and $60 million at December 31, 2019 and 2018, respectively, which are guaranteed by Leonardo S.p.A.

Surplus Treasury Agreement

We entered into a surplus treasury agreement with US Holding (the “Surplus Agreement”) in December 2019. The Surplus Agreement allows us to advance excess funds to US Holding when funds are available. The advances bear interest at LIBOR plus between five and 20 basis points depending on the tenor of the advance. As of December 31, 2019, we had advanced $100.0 million to US Holding, which is presented on our balance sheet as a related-party note receivable. The advance under the Surplus Treasury Agreement was repaid in January of 2020.

For a discussion of certain recapitalization transactions that Leonardo S.p.A. and its affiliates and we have entered into or will enter into in connection with this offering, see “Recapitalization.”

Director Indemnification Agreements

Prior to the completion of this offering, we will enter into indemnification agreements with our directors. The indemnification agreements will provide the directors with contractual rights to indemnification and expense rights. See “Description of Capital Stock—Limitations on Liability and Indemnification” and the Form of Director Indemnification Agreement filed as Exhibit     to the registration statement of which this prospectus forms a part.

153

DESCRIPTION OF CAPITAL STOCK

The following description of our capital stock is a summary of the material terms of our amended and restated certificate of incorporation, amended and restated by-laws and the amended and restated proxy agreement. Reference is made to the more detailed provisions of, and the descriptions are qualified in their entirety by reference to, these documents, forms of which are filed with the SEC as exhibits to the registration statement of which this prospectus is a part, and applicable law. This description assumes the effectiveness of our amended and restated certificate of incorporation and amended and restated by-laws, which will take effect prior to this offering.

General

Our authorized capital stock consists of     shares of common stock, par value $0.01 per share, and     shares of undesignated preferred stock, par value $0.01 per share. There are     shares of our common stock issued and outstanding.

Common Stock

Holders of common stock will be entitled:

•to cast one vote for each share held of record on all matters submitted to a vote of the stockholders;

•to receive, on a pro rata basis, dividends and distributions, if any, that our board may declare out of legally available funds, subject to preferences that may be applicable to preferred stock, if any, then outstanding; and

•upon our liquidation, dissolution or winding up, to share equally and ratably in any assets remaining after the payment of all debt and other liabilities, subject to the prior rights, if any, of holders of any outstanding shares of preferred stock.

The holders of our common stock will not have any preemptive, cumulative voting, subscription, conversion, redemption or sinking fund rights. The common stock will not be subject to future calls or assessments by us. The rights and privileges of holders of our common stock are subject to any series of preferred stock that we may issue in the future, as described below.

Before the date of this prospectus, there has been no public market for our common stock.

As of     , 2021, we had     shares of common stock outstanding all of which were held of record by US Holding.

Preferred Stock

Under our amended and restated certificate of incorporation, our board will have the authority to issue up to     shares of preferred stock in one or more series and to fix the voting powers, designations, preferences and the relative participating, optional or other special rights and qualifications, limitations and restrictions of each series, including, without limitation, dividend rights, dividend rates, conversion rights, voting rights, terms of redemption, liquidation preferences and the number of shares constituting any series. Following this offering, no shares of our authorized preferred stock will be outstanding. Because the board will have the power to establish the preferences and rights of the shares of any additional series of preferred stock, it may afford holders of any preferred stock preferences, powers and rights, including voting and dividend rights, senior to the rights of holders of our common stock, which could adversely affect the holders of the common stock and could delay, discourage or prevent a takeover of us even if a change of control of our company would be beneficial to the interests of our stockholders.

154

Authorized but Unissued Capital Stock

The DGCL does not generally require stockholder approval for the issuance of authorized shares. These additional shares may be used for a variety of corporate purposes, including future public offerings, to raise additional capital or to facilitate acquisitions. However, the listing requirements of     , which would apply so long as the common stock remains listed on      , require stockholder approval of certain issuances equal to or exceeding 20% of the then-outstanding voting power or then-outstanding number of shares of common stock.

Registration Rights

US Holding has certain rights to cause the registration of our common stock for resale pursuant to a stockholders’ agreement. See “Certain Relationships and Related Party Transactions—Cooperation Agreement.”

Annual Stockholders Meeting

Our amended and restated by-laws will provide that annual stockholders meetings will be held at a date, time and place, if any, as exclusively selected by our board. To the extent permitted under applicable law, we may conduct meetings by remote communications, including by webcast.

Voting

The affirmative vote of a plurality of the shares of our common stock present, in person or by proxy, at the meeting and entitled to vote on the election of directors will decide the election of any directors, and the affirmative vote of a majority of the shares of our common stock present, in person or by proxy, at the meeting and entitled to vote at any annual or special meeting of stockholders will decide all other matters voted on by stockholders, unless the question is one upon which, by express provision of law, under our amended and restated certificate of incorporation, or under our amended and restated by-laws, a different vote is required, in which case such provision will control. Stockholders do not have the right to cumulate their votes for the election of directors.

Proxy Agreement

We have entered into a proxy agreement, dated as of October 26, 2017, with the proxy holders, Leonardo S.p.A., US Holding and the DoD. Following this offering we expect to enter into an amended and restated proxy agreement (as amended and restated, the “proxy agreement”) and the parties to the proxy agreement have entered into a commitment letter, dated as of     , 2020, as to the form and content of the amended and restated proxy agreement which allows us to operate as if the amended and restated proxy agreement were already in effect. The proxy agreement requires the appointment of five proxy holders, who must be independent from prior affiliation with Leonardo S.p.A. and its subsidiaries (including US Holding and us) and maintain adequate security clearance, to vote the shares of our common stock owned directly or indirectly by Leonardo S.p.A. Proxy holders are appointed by US Holding after consultation with Leonardo S.p.A. and approval by the DCSA and serve for staggered three-year terms. The proxy holders may vote for or consent to certain specified matters only with the express written approval of US Holding, as set forth under “Certain Relationships and Related-Party Transactions—Relationship with Leonardo S.p.A Following this Offering—Proxy Agreement” and may vote for or consent to all other matters in their sole and absolute discretion, without consultation with US Holding or Leonardo S.p.A. The proxy agreement contains a number of other provisions which are intended to restrict the ability of Leonardo S.p.A. to control our operations. See “Certain Relationships and Related-Party Transactions—Relationship with Leonardo S.p.A Following this Offering—Proxy Agreement.”

Board Designation Rights. Pursuant to the proxy agreement, Leonardo S.p.A., US Holding, the DCSA and the proxy holders will have specified board designation and/or approval and other rights following this offering. The proxy agreement requires that our board include the five proxy holders appointed by US Holding after consultation with Leonardo S.p.A. and approval by the DCSA. The proxy

155

agreement also requires our board to include four additional directors consisting of our chief executive officer and three additional candidates proposed by US Holding in reasonable consultation with the nominating and corporate governance committee, subject to approval of the DCSA in certain circumstances. See “Certain Relationships and Related-Party Transactions—Relationship with Leonardo S.p.A Following this Offering—Proxy Agreement.”

Removal of Directors. Our amended and restated certificate of incorporation will provide that, for so long as the proxy agreement is in effect, directors may be removed pursuant to the terms set forth in the proxy agreement. During their terms, proxy holders may only be removed (i) for acts in violation of the proxy agreement upon petition by US Holding to DCSA which may be granted or denied by DCSA in its sole discretion or (ii) for gross negligence or willful misconduct. The proxy holders may remove any non-proxy holder director from our board by majority vote and after consultation with US Holding. See “Certain Relationships and Related-Party Transactions—Relationship with Leonardo S.p.A Following this Offering—Proxy Agreement”.

Anti-Takeover Effects of Our Certificate of Incorporation and By-laws

The provisions of our amended and restated certificate of incorporation and amended and restated by-laws summarized below may have an anti-takeover effect and may delay, defer or prevent a tender offer or takeover attempt that you might consider in your best interest, including an attempt that might result in your receipt of a premium over the market price for your shares. These provisions are also designed, in part, to encourage persons seeking to acquire control of us to first negotiate with our board, which could result in an improvement of their terms.

Authorized but Unissued Shares of Common Stock. Following this offering, our shares of authorized and unissued common stock will be available for future issuance without additional stockholder approval. While our authorized and unissued shares are not designed to deter or prevent a change of control, under some circumstances we could use the additional shares to create voting impediments or to frustrate persons seeking to effect a takeover or otherwise gain control by, for example, issuing those shares in private placements to purchasers who might side with our board in opposing a hostile takeover bid.

Authorized but Unissued Shares of Preferred Stock. Under our amended and restated certificate of incorporation, our board will have the authority to issue up to shares of preferred stock in one or more series and to fix the voting powers, designations, preferences and the relative participating, optional or other special rights and qualifications, limitations and restrictions of each series, including, without limitation, dividend rights, dividend rates, conversion rights, voting rights, terms of redemption, liquidation preferences and the number of shares constituting any series. The existence of authorized but unissued preferred stock could reduce our attractiveness as a target for an unsolicited takeover bid since we could, for example, issue shares of preferred stock to parties who might oppose such a takeover bid or shares that contain terms the potential acquiror may find unattractive. This may have the effect of delaying or preventing a change of control, may discourage bids for the common stock at a premium over the market price of the common stock, and may adversely affect the market price of, and the voting and other rights of the holders of, our common stock.

Special Meetings of Stockholders. Our amended and restated certificate of incorporation will provide that a special meeting of stockholders may be called only by the chairman of our board or chief executive officer or by a resolution adopted by a majority of our board. Special meetings may also be called by our corporate secretary at the request of the holders of at least a majority of the outstanding shares of our common stock prior to the termination of the proxy agreement. Thereafter, stockholders will not be permitted to call a special meeting of stockholders.

Stockholders Advance Notice Procedure. Our amended and restated by-laws will establish an advance notice procedure for stockholders to make nominations of candidates for election as directors or to bring other business before an annual meeting of our stockholders. The amended and restated by-laws

156

will provide that any stockholders wishing to nominate persons for election as directors at, or bring other business before, an annual meeting must deliver to our corporate secretary a written notice of the stockholder’s intention to do so. These provisions may have the effect of precluding the conduct of certain business at a meeting if the proper procedures are not followed. We expect that these provisions may also discourage or deter a potential acquirer from conducting a solicitation of proxies to elect the acquirer’s own slate of directors or otherwise attempting to obtain control of our company. To be timely, the stockholder’s notice must be delivered to our corporate secretary at our principal executive offices not less than 90 days nor more than 120 days before the first anniversary date of the annual meeting for the preceding year; provided, however, that in the event that the annual meeting is set for a date that is more than 30 days before or delayed by more than 60 days after the first anniversary date of the preceding year’s annual meeting, a stockholder’s notice must be delivered to our corporate secretary not later than the later of (x) the close of business on the 90th day prior to the meeting or (y) the close of business on the 10th day following the day on which a public announcement of the date of the meeting is first made by us.

No Stockholders Action by Written Consent. Our amended and restated certificate of incorporation will provide that stockholders action may be taken only at an annual meeting or special meeting of stockholders, provided that, until the proxy agreement terminates, stockholders action may be taken by written consent in lieu of a meeting.

Amendments to Certificate of Incorporation and By-laws. Our amended and restated certificate of incorporation will provide that our amended and restated certificate of incorporation may be amended by both the affirmative vote of a majority of our board and the affirmative vote of the holders of a majority of the outstanding shares of our common stock then entitled to vote at any annual or special meeting of stockholders; provided that, following termination of the proxy agreement, specified provisions of our amended and restated certificate of incorporation may not be amended, altered or repealed unless the amendment is approved by the affirmative vote of the holders of at least 66 2⁄3% of the outstanding shares of our common stock then entitled to vote at any annual or special meeting of stockholders, including, but not limited to, the provisions governing:

•liability and indemnification of directors;

•corporate opportunities;

•elimination of stockholders action by written consent;

•prohibition on the rights of stockholders to call a special meeting; and

•required approval of the holders of at least 66 2⁄3% of the outstanding shares of our common stock to amend our amended and restated by-laws and certain provisions of our amended and restated certificate of incorporation.

In addition, our amended and restated by-laws may be amended, altered or repealed, or new by-laws may be adopted, by the affirmative vote of a majority of the board, or by the affirmative vote of the holders of (x) prior to termination of the proxy agreement, at least a majority and (y) thereafter, at least 66 2⁄3%, of the outstanding shares of our common stock then entitled to vote at any annual or special meeting of stockholders.

These provisions make it more difficult for any person to remove or amend any provisions in our amended and restated certificate of incorporation and amended and restated by-laws that may have an anti-takeover effect.

Delaware Anti-Takeover Law. In general, Section 203 prohibits a publicly held Delaware corporation from engaging in a business combination, such as mergers, sales and leases of assets, issuances of securities and similar transactions by a corporation or subsidiary with an interested stockholder including a person or group who beneficially owns 15% or more of the corporation’s voting stock for a period of

157

three years following the date the person became an interested stockholder, unless (with certain exceptions) the business combination or the transaction in which the person became an interested stockholder is approved in a prescribed manner. Section 203 permits corporations, in their certificate of incorporation, to opt out of the protections of Section 203. Our certificate of incorporation generally excepts Leonardo S.p.A. and all of its affiliates, including US Holding, and all transferees of our stock or preferred stock receiving shares from Leonardo S.p.A. or any of its affiliates, including US Holding, or any affiliate of any such transferee, from the definition of interested stockholder for purposes of Section 203 of the DGCL until the occurrence of a transaction in which Leonardo S.p.A. or its affiliates, including US Holding, cease to collectively, as applicable, beneficially own at least 15% of the voting power of our outstanding voting stock.

Limitations on Liability and Indemnification

Our amended and restated certificate of incorporation will contain provisions relating to the liability of directors. These provisions will eliminate a director’s personal liability for monetary damages resulting from a breach of fiduciary duty, except in circumstances involving:

•any breach of the director’s duty of loyalty;

•acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of the law;

•unlawful payments of dividends or unlawful stock repurchases, redemptions or other distributions; or

•any transaction from which the director derives an improper personal benefit.

The principal effect of the limitation on liability provision is that a stockholder will be unable to prosecute an action for monetary damages against a director unless the stockholder can demonstrate a basis for liability for which indemnification is not available under the DGCL. These provisions, however, should not limit or eliminate our rights or any stockholder’s rights to seek non-monetary relief, such as an injunction or rescission, in the event of a breach of director’s fiduciary duty. These provisions will not alter a director’s liability under federal securities laws. The inclusion of this provision in our amended and restated certificate of incorporation may discourage or deter stockholders or management from bringing a lawsuit against directors for a breach of their fiduciary duties, even though such an action, if successful, might otherwise have benefited us and our stockholders. In addition, your investment may be adversely affected to the extent we pay costs of settlement and damage awards against directors and officers pursuant to these indemnification provisions.

Our amended and restated certificate of incorporation and our amended and restated by-laws will require us to indemnify and advance expenses to our directors and officers to the fullest extent not prohibited by the DGCL and other applicable law, except in the case of a proceeding instituted by the director without the approval of our board. Our amended and restated certificate of incorporation and our amended and restated by-laws will provide that we are required to indemnify our directors and executive officers, to the fullest extent permitted by law, for all judgments, fines, settlements, legal fees and other expenses incurred in connection with pending or threatened legal proceedings because of the director’s or officer’s positions with us or another entity that the director or officer serves at our request, subject to various conditions, and to advance funds to our directors and officers to enable them to defend against such proceedings. To receive indemnification, the director or officer must have been successful in the legal proceeding or have acted in good faith and in what was reasonably believed to be a lawful manner in our best interest and, with respect to any criminal proceeding, have had no reasonable cause to believe his or her conduct was unlawful.

Prior to this offering, we will enter into an indemnification agreement with each of our directors. The indemnification agreement will provide our directors with contractual rights to the indemnification and expense advancement rights provided under our amended and restated by-laws, as well as contractual

158

rights to additional indemnification as provided in the indemnification agreement. See the Form of Director Indemnification Agreement filed as Exhibit     to the registration statement of which this prospectus forms a part.

Corporate Opportunities

Our amended and restated certificate of incorporation will provide that we, on our behalf and on behalf of our subsidiaries, renounce any interest or expectancy in, or in being offered an opportunity to participate in, potential transactions, matters or business opportunities (each, a “corporate opportunity”) that are from time to time presented to Leonardo S.p.A. or any of its officers, directors, employees, agents, stockholders, members, partners, affiliates or subsidiaries (other than us and our subsidiaries), with the exception of the proxy holders, even if the opportunity is one that we or our subsidiaries might reasonably be deemed to have pursued or had the ability or desire to pursue if granted the opportunity to do so. Neither Leonardo S.p.A. nor any of its officers, directors, employees, agents, stockholders, members, partners, affiliates or subsidiaries, with the exception of the proxy holders, will be liable to us or any of our subsidiaries for breach of any fiduciary or other duty by reason of the fact that such person pursues or acquires such corporate opportunity, directs such corporate opportunity to another person or fails to present such corporate opportunity, or information regarding such corporate opportunity, to us or our subsidiaries. To the fullest extent permitted by law, by becoming a stockholder in our company, stockholders will be deemed to have notice of and consented to this provision of our amended and restated certificate of incorporation.

Choice of Forum

Our amended and restated certificate of incorporation will provide that, unless we consent in writing to the selection of an alternate forum, the Court of Chancery of the State of Delaware will, to the fullest extent provided by law, be the sole and exclusive forum for (i) any derivative action or proceeding brought on our behalf, (ii) any action asserting a claim of breach of a fiduciary duty owed to us or our stockholders by any of our directors, officers, other employees, agents or stockholders, (iii) any action asserting a claim against us arising under the DGCL or as to which the DGCL confers jurisdiction on the Court of Chancery of the State of Delaware (including, without limitation, any action asserting a claim arising out of or pursuant to our amended and restated by-laws) or (iv) any action asserting a claim against us that is governed by the internal affairs doctrine. The foregoing provision does not apply to claims arising under the Securities Act, the Securities Exchange Act, or other federal securities laws for which there is exclusive federal or concurrent federal and state jurisdiction. Our stockholders cannot waive compliance with the federal securities laws and the rules and regulations thereunder. Furthermore, unless we select or consent to the selection of an alternative forum, our amended and restated certificate of incorporation will provide that the federal district courts of the United States of America will be the exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act. To the fullest extent permitted by law, by becoming a stockholder in our company, you will be deemed to have notice of and have consented to the provisions of our amended and restated certificate of incorporation related to choice of forum.

SHARES ELIGIBLE FOR FUTURE SALE

Immediately prior to this offering, there was no public market for our common stock. Sales of substantial amounts of our common stock in the public market could adversely affect prevailing market prices of our common stock. Some shares of our common stock will not be available for sale for a certain period of time after this offering because they are subject to contractual and legal restrictions on resale some of which are described below. Sales of substantial amounts of common stock in the public market after these restrictions lapse, or the perception that these sales could occur, could adversely affect the prevailing market price and our ability to raise equity capital in the future.

Sales of Restricted Securities

Currently,     shares of our common stock are outstanding. Of these shares,     shares sold in this offering (or     shares if the underwriters exercise their option to purchase additional shares of common stock from the selling stockholder in full) will be freely tradable without restriction under the Securities Act, unless purchased by our “affiliates,” as that term is defined in Rule 144 under the Securities Act. The remaining     shares of our common stock (or     shares if the underwriters exercise their option to purchase additional shares of common stock from the selling stockholder in full) that will be outstanding after this offering are “restricted securities” within the meaning of Rule 144 under the Securities Act. Restricted securities may be sold in the public market only if they are registered under the Securities Act or are sold pursuant to an exemption from registration under Rule 144 under the Securities Act, which is summarized below. Subject to the lock-up agreements described below, shares held by our affiliates that are not restricted securities or that have been owned for more than one year may be sold subject to compliance with Rule 144 of the Securities Act without regard to the prescribed one-year holding period under Rule 144.

Registration Statement on Form S-8

We intend to file with the SEC, as soon as practicable following this offering, a registration statement on Form S‑8 registering an aggregate of shares of common stock underlying equity awards we will make to our employees and certain other qualifying individuals. The Form S‑8 will become effective upon filing and shares of common stock so registered will become freely tradable upon such effectiveness, subject to any restrictions imposed on such resale pursuant to the lock-up agreements entered into with the underwriters for the offering.

Lock-up Agreements

In connection with this offering, the selling stockholder and our directors and executive officers will enter into lock-up agreements, under which they will agree not to dispose of or hedge any of our common stock or securities convertible into or exchangeable for shares of our common stock without the prior written consent of Goldman Sachs & Co. LLC for a period of 180 days after the date of this prospectus. These agreements are described below under “Underwriting.”

Rule 144

In general, under Rule 144, as currently in effect, a person (or persons whose shares are aggregated) who is not deemed to be or have been at any time during the 90 days preceding a sale one of our affiliates for purposes of the Securities Act and who has beneficially owned the shares proposed to be sold for at least six months, including the holding period of any prior owner other than an affiliate, is entitled to sell such shares without registration, subject to compliance with the public information requirements of Rule 144. If such a person has beneficially owned the shares proposed to be sold for at least one year, including the holding period of a prior owner other than an affiliate, then such person is entitled to sell such shares without complying with any of the requirements of Rule 144.

In general, under Rule 144, as currently in effect, our affiliates or persons selling shares on behalf of our affiliates, who have met the six-month holding period for beneficial ownership of “restricted shares” of

160

our common stock, are entitled to sell within any three-month period, a number of shares that does not exceed the greater of:

•1% of the number of shares of our common stock then outstanding, which will equal approximately     shares immediately after this offering (or     shares if the underwriters exercise their option to purchase additional shares of common stock from the selling stockholder in full); and

•the average reported weekly trading volume of our common stock on     during the four calendar weeks preceding the date of filing a Notice of Proposed Sale of Securities Pursuant to Rule 144 with respect to the sale.

Sales under Rule 144 by our affiliates or persons selling shares on behalf of our affiliates are also subject to certain manner of sale provisions and notice requirements and to the availability of current public information about us. The sale of these shares, or the perception that sales will be made, could adversely affect the price of our common stock after this offering because a great supply of shares would be, or would be perceived to be, available for sale in the public market.

161

MATERIAL U.S. FEDERAL TAX CONSIDERATIONS FOR NON-U.S. HOLDERS

The following is a discussion of material U.S. federal income tax considerations relating to the purchase, ownership and disposition of our common stock by Non-U.S. Holders (as defined below) that purchase such common stock pursuant to this offering and hold such common stock as a capital asset. This discussion is based on the U.S. Internal Revenue Code of 1986, as amended (the “Code”), U.S. Treasury regulations promulgated or proposed thereunder, and administrative and judicial interpretations thereof, all as in effect on the date hereof and all of which are subject to change, possibly with retroactive effect, or to different interpretation. This discussion does not address all of the U.S. federal income tax considerations that may be relevant to specific Non-U.S. Holders in light of their particular circumstances or to Non-U.S. Holders subject to special treatment under U.S. federal income tax law (such as banks, insurance companies, dealers in securities or other Non-U.S. Holders that generally mark their securities to market for U.S. federal income tax purposes, Non-U.S. Holders that are “controlled foreign corporations” or “passive foreign investment companies” for U.S. federal income tax purposes, foreign governments, international organizations, tax-exempt entities, certain former citizens or residents of the United States, Non-U.S. Holders that hold our common stock as part of a straddle, hedge, conversion or other integrated transaction, or Non-U.S. Holders that purchase or sell our common stock as part of a wash sale for tax purposes). This discussion does not address any U.S. state or local or non-U.S. tax considerations or any U.S. federal estate and gift, Medicare contribution or alternative minimum tax considerations.

As used in this discussion, the term “Non-U.S. Holder” means a beneficial owner of our common stock that, for U.S. federal income tax purposes, is:

•an individual who is neither a citizen nor a resident of the United States;

•a corporation that is not created or organized in or under the laws of the United States, any state thereof, or the District of Columbia or otherwise treated as a domestic corporation;

•an estate that is not subject to U.S. federal income tax on income from non-U.S. sources which is not effectively connected with the conduct of a trade or business in the United States; or

•a trust unless (i) a court within the United States is able to exercise primary supervision over its administration and one or more U.S. persons have the authority to control all of its substantial decisions or (ii) it has in effect a valid election under applicable U.S. Treasury regulations to be treated as a U.S. person.

If an entity or arrangement that is treated as a partnership for U.S. federal income tax purposes invests in our common stock, the U.S. federal income tax considerations relating to such investment will depend in part upon the status and activities of such entity and the particular partner. Any such entity should consult its own tax advisor regarding the U.S. federal income tax considerations applicable to it and its partners relating to the purchase, ownership and disposition of our common stock.

PERSONS CONSIDERING AN INVESTMENT IN OUR COMMON STOCK SHOULD CONSULT THEIR OWN TAX ADVISORS REGARDING THE U.S. FEDERAL, STATE AND LOCAL AND NON-U.S. INCOME, ESTATE AND OTHER TAX CONSIDERATIONS RELATING TO THE PURCHASE, OWNERSHIP AND DISPOSITION OF OUR COMMON STOCK IN LIGHT OF THEIR PARTICULAR CIRCUMSTANCES.

Distributions on Common Stock

If we make a distribution of cash or other property (other than certain pro rata distributions of our common stock or rights to acquire our common stock) with respect to a share of our common stock, the distribution generally will be treated as a dividend to the extent it is paid from our current or accumulated earnings and profits (as determined under U.S. federal income tax principles). If the amount of such distribution exceeds our current and accumulated earnings and profits, such excess generally will be

162

treated first as a tax-free return of capital to the extent of the Non-U.S. Holder’s adjusted tax basis in such share of our common stock, and then as capital gain (which will be treated in the manner described below under “—Sale, Exchange or Other Disposition of Common Stock”). Subject to the following paragraph, distributions treated as dividends on our common stock that are paid to or for the account of a Non-U.S. Holder generally will be subject to U.S. federal withholding tax at a rate of 30%, or at a lower rate if provided by an applicable tax treaty and the Non-U.S. Holder provides the documentation (generally, Internal Revenue Service (“IRS”) Form W-8BEN or W-8BEN-E) required to claim benefits under such tax treaty to the applicable withholding agent. Even if our current or accumulated earnings and profits are less than the amount of the distribution, the applicable withholding agent may elect to treat the entire distribution as a dividend for U.S. federal withholding tax purposes. Each Non-U.S. Holder should consult its own tax advisor regarding U.S. federal withholding tax on distributions, including such Non-U.S. Holder’s eligibility for a lower rate and the availability of a refund of any excess U.S. federal tax withheld.

If, however, a dividend is effectively connected with the conduct of a trade or business in the United States by a Non-U.S. Holder, such dividend generally will not be subject to the 30% U.S. federal withholding tax if such Non-U.S. Holder provides the appropriate documentation (generally, IRS Form W-8ECI) to the applicable withholding agent. Instead, such Non-U.S. Holder generally will be subject to U.S. federal income tax on such dividend in substantially the same manner as a U.S. person (except as provided by an applicable tax treaty). In addition, a Non-U.S. Holder that is treated as a corporation for U.S. federal income tax purposes may be subject to a branch profits tax at a rate of 30% (or a lower rate if provided by an applicable tax treaty) on its effectively connected income for the taxable year, subject to certain adjustments.

The foregoing discussion is subject to the discussion below under “—FATCA Withholding” and “—Information Reporting and Backup Withholding.”

Sale, Exchange or Other Disposition of Common Stock

A Non-U.S. Holder generally will not be subject to U.S. federal income tax on any gain recognized on the sale, exchange or other disposition of our common stock unless:

(i)such gain is effectively connected with the conduct of a trade or business in the United States by such Non-U.S. Holder, in which event such Non-U.S. Holder generally will be subject to U.S. federal income tax on such gain in substantially the same manner as a U.S. person (except as provided by an applicable tax treaty) and, if it is treated as a corporation for U.S. federal income tax purposes, may also be subject to a branch profits tax at a rate of 30% (or a lower rate if provided by an applicable tax treaty);

(ii)such Non-U.S. Holder is an individual who is present in the United States for 183 days or more during the taxable year of such sale, exchange or other disposition and certain other conditions are met, in which event such gain (net of certain U.S. source losses) generally will be subject to U.S. federal income tax at a rate of 30% (except as provided by an applicable tax treaty); or

(iii)we are or have been a “United States real property holding corporation” for U.S. federal income tax purposes at any time during the shorter of (x) the five-year period ending on the date of such sale, exchange or other disposition and (y) such Non-U.S. Holder’s holding period with respect to such common stock, and certain other conditions are met.

Generally, a corporation is a “United States real property holding corporation” if the fair market value of its United States real property interests equals or exceeds 50% of the sum of the fair market value of its worldwide real property interests and its other assets used or held for use in a trade or business (all as determined for U.S. federal income tax purposes). We believe that we presently are not, and we do not presently anticipate that we will become, a United States real property holding corporation.

The foregoing discussion is subject to the discussion below under “Information Reporting and Backup Withholding.”

163

FATCA Withholding

Pursuant to sections 1471 through 1474 of the Code, commonly known as the Foreign Account Tax Compliance Act (“FATCA”), a 30% withholding tax (“FATCA withholding”) will generally be imposed on certain payments to you or to certain foreign financial institutions, investment funds and other non-US persons receiving payments on your behalf if you or such persons fail to comply with certain information reporting requirements. Payments of dividends that you receive in respect of common stock could be affected by this withholding if you are subject to the FATCA information reporting requirements and fail to comply with them or if you hold common stock through a non-US person (e.g., a foreign bank or broker) that fails to comply with these requirements (even if payments to you would not otherwise have been subject to FATCA withholding). In order to be treated as FATCA compliant, a Non-U.S. Holder must provide certain documentation (usually an IRS Form W-8BEN or W-8BEN-E) containing information about its identity, its FATCA status and, if required, its direct and indirect U.S. owners. These requirements may be modified by the adoption or implementation of a particular intergovernmental agreement between the United States and another country or by future U.S. Treasury Regulations. Documentation that Non-U.S. Holders provide in order to be treated as FATCA compliant may be reported to the IRS and other tax authorities, including information about a Non-U.S. Holder’s identity, its FATCA status, and if applicable, its direct and indirect U.S. owners. You should consult your own tax advisors regarding the relevant U.S. law and other official guidance on FATCA withholding.

Information Reporting and Backup Withholding

Amounts treated as payments of dividends on our common stock paid to a Non-U.S. Holder and the amount of any U.S. federal tax withheld from such payments generally will be reported annually to the IRS and to such Non-U.S. Holder by the applicable withholding agent.

The information reporting and backup withholding rules that apply to payments of dividends to certain U.S. persons generally will not apply to payments of dividends on our common stock to a Non-U.S. Holder if such Non-U.S. Holder certifies under penalties of perjury that it is not a U.S. person (generally by providing an IRS Form W-8BEN or W-8BEN-E to the applicable withholding agent) or otherwise establishes an exemption.

Proceeds from the sale, exchange or other disposition of our common stock by a Non-U.S. Holder effected outside the United States through a non-U.S. office of a non-U.S. broker generally will not be subject to the information reporting and backup withholding rules that apply to payments to certain U.S. persons, provided that the proceeds are paid to the Non-U.S. Holder outside the United States. However, proceeds from the sale, exchange or other disposition of our common stock by a Non-U.S. Holder effected through a non-U.S. office of a non-U.S. broker with certain specified U.S. connections or of a U.S. broker generally will be subject to these information reporting rules (but generally not to these backup withholding rules), even if the proceeds are paid to such Non-U.S. Holder outside the United States, unless such Non-U.S. Holder certifies under penalties of perjury that it is not a U.S. person (generally by providing an IRS Form W-8BEN or W-8BEN-E to the applicable withholding agent) or otherwise establishes an exemption. Proceeds from the sale, exchange or other disposition of our common stock by a Non-U.S. Holder effected through a U.S. office of a broker generally will be subject to these information reporting and backup withholding rules unless such Non-U.S. Holder certifies under penalties of perjury that it is not a U.S. person (generally by providing an IRS Form W-8BEN or W-8BEN-E to the applicable withholding agent) or otherwise establishes an exemption.

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules generally will be allowed as a refund or a credit against a Non-U.S. Holder’s U.S. federal income tax liability if the required information is furnished by such Non-U.S. Holder on a timely basis to the IRS.

164

UNDERWRITING

The Company, US Holding (the selling stockholder) and the underwriters named below have entered into an underwriting agreement dated the date of this prospectus with respect to the shares being offered. Subject to certain conditions, each underwriter has severally agreed to purchase the number of shares indicated in the following table. Goldman Sachs & Co. LLC is the representative of the underwriters.

Underwriters	Number of Shares
Goldman Sachs & Co. LLC
Total

The underwriters are committed to take and pay for all of the shares being offered, if any are taken, other than the shares covered by the option described below unless and until this option is exercised.

The underwriters will have an option to buy up to an additional     shares from US Holding to cover sales by the underwriters of a greater number of shares than the total number set forth in the table above at the public offering price listed on the cover page of this prospectus, less underwriting discounts and commissions. They may exercise that option for 30 days from the date of this prospectus. If any shares are purchased pursuant to this option, the underwriters will severally purchase shares in approximately the same proportion as set forth in the table above.

The Company will not receive any proceeds from this offering.

The following table shows the per share and total underwriting discounts and commissions to be paid to the underwriters by US Holding. Such amounts are shown assuming both no exercise and full exercise of the underwriters’ option to purchase     additional shares.

Paid by US Holding
	No Exercise	Full Exercise
Per Share	$	$
Total	$	$

Shares sold by the underwriters to the public will initially be offered at the initial public offering price set forth on the cover page of this prospectus. Any shares sold by the underwriters to securities dealers may be sold at a discount of up to $     per share from the initial public offering price. After the initial offering of the shares, the representative may change the offering price and the other selling terms. The offering of the shares by the underwriters is subject to receipt and acceptance and subject to the underwriters’ right to reject any order in whole or in part.

We, US Holding and our executive officers and directors have agreed with the underwriters, subject to certain exceptions, not to dispose of or hedge any common stock or securities convertible into or exchangeable for shares of common stock during the period from the date of this prospectus continuing through the date 180 days after the date of this prospectus, except with the prior written consent of Goldman Sachs & Co. LLC. See “Shares Eligible for Future Sale” for a discussion of certain transfer restrictions.

Prior to the offering, there has been no public market for the shares. The initial public offering price has been negotiated among us, US Holding, Leonardo S.p.A. and the representative. Among the factors considered in determining the initial public offering price of the shares, in addition to prevailing market conditions, were our historical performance, estimates of our business potential and earnings prospects, an assessment of our management and the consideration of the above factors in relation to market valuation of companies in related businesses.

An application has been made to list the common stock on the     under the symbol “           .”

165

In connection with the offering, the underwriters may purchase and sell shares of common stock in the open market. These transactions may include short sales, stabilizing transactions and purchases to cover positions created by short sales. Short sales involve the sale by the underwriters of a greater number of shares than they are required to purchase in the offering, and a short position represents the amount of such sales that have not been covered by subsequent purchases. A “covered short position” is a short position that is not greater than the amount of additional shares for which the underwriters’ option described above may be exercised. The underwriters may cover any covered short position by either exercising their option to purchase additional shares or purchasing shares in the open market. In determining the source of shares to cover the covered short position, the underwriters will consider, among other things, the price of shares available for purchase in the open market as compared to the price at which they may purchase additional shares pursuant to the option described above. “Naked” short sales are any short sales that create a short position greater than the amount of additional shares for which the option described above may be exercised. The underwriters must cover any such naked short position by purchasing shares in the open market. A naked short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of the common stock in the open market after pricing that could adversely affect investors who purchase in the offering. Stabilizing transactions consist of various bids for or purchases of common stock made by the underwriters in the open market prior to the completion of the offering.

The underwriters may also impose a penalty bid. This occurs when a particular underwriter repays to the underwriters a portion of the underwriting discount received by it because the representative has repurchased shares sold by or for the account of such underwriter in stabilizing or short covering transactions.

Purchases to cover a short position and stabilizing transactions, as well as other purchases by the underwriters for their own accounts, may have the effect of preventing or retarding a decline in the market price of our common stock, and together with the imposition of the penalty bid, may stabilize, maintain or otherwise affect the market price of the common stock. As a result, the price of the common stock may be higher than the price that otherwise might exist in the open market. The underwriters are not required to engage in these activities and may end any of these activities at any time. These transactions may be effected on the relevant exchange, in the over‑the‑counter market or otherwise.

We and US Holding estimate that the total expenses of the offering, excluding underwriting discounts and commissions, will be approximately $           , approximately $          of which has been or will be paid or reimbursed to us by US Holding. The selling stockholder has also agreed to reimburse the underwriters for certain expenses.

We and US Holding and the underwriters have agreed to indemnify each other against certain liabilities, including liabilities under the Securities Act, or to contribute to payments that each party may be required to make in respect of those liabilities.

The underwriters and their respective affiliates are full service financial institutions engaged in various activities, which may include sales and trading, commercial and investment banking, advisory, investment management, investment research, principal investment, hedging, market making, brokerage and other financial and non‑financial activities and services. Certain of the underwriters and their respective affiliates have provided, and may in the future provide, a variety of these services to the Company and Leonardo S.p.A. and to persons and entities with relationships with the Company and Leonardo S.p.A., for which they received or will receive customary fees and expenses.

In the ordinary course of their various business activities, the underwriters and their respective affiliates, officers, directors and employees may purchase, sell or hold a broad array of investments and actively trade securities, derivatives, loans, commodities, currencies, credit default swaps and other financial instruments for their own account and for the accounts of their customers, and such investment and trading activities may involve or relate to assets, securities and/or instruments of the Company (directly, as collateral securing other obligations or otherwise) and/or persons and entities with

166

relationships with the Company. The underwriters and their respective affiliates may also communicate independent investment recommendations, market color or trading ideas and/or publish or express independent research views in respect of such assets, securities or instruments and may at any time hold, or recommend to clients that they should acquire, long and/or short positions in such assets, securities and instruments.

Selling Restrictions

Pursuant to section 3A.3 of National Instrument 33‑105 Underwriting Conflicts (“NI 33‑105”), the underwriters are not required to comply with the disclosure requirements of NI 33‑105 regarding underwriter conflicts of interest in connection with this offering

European Economic Area and the United Kingdom

This prospectus is not a prospectus for the purposes of the Prospectus Regulation (as defined below). This prospectus has been prepared on the basis that any offer of shares in any Member States of the European Economic Area (the “EEA”) or in the United Kingdom (each, a “Relevant State”) will be made pursuant to an exemption under the Prospectus Regulation from the requirement to publish a prospectus for offers of shares. Accordingly any person making or intending to make an offer in that Relevant State of shares which are the subject of the offering contemplated in this prospectus may only do so in circumstances in which no obligation arises for the Company or any of the underwriters to publish a prospectus pursuant to Article 3 of the Prospectus Regulation or supplement a prospectus pursuant to Article 23 of the Prospectus Regulation in relation to such offer. Neither the Company nor the underwriters have authorized, nor do they authorize, the making of any offer of shares in circumstances in which an obligation arises for the Company or the underwriters to publish a prospectus for such offer.

In relation to each Relevant State, no offer of shares which are the subject of the offering contemplated by this prospectus (“Securities”) have been offered or will be offered pursuant to the offering to the public in that Relevant State, other than:

(a)to any legal entity which is a qualified investor as defined under the Prospectus Regulation

Report of Independent Registered Public Accounting Firm

To the Shareholder and Board of Directors

Leonardo DRS, Inc.:

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheet of Leonardo DRS, Inc. and subsidiaries (the Company) as of December 31, 2019, the related consolidated statements of earnings, comprehensive income (loss), shareholder’s equity, and cash flows for each of the years in the two-year period ended December 31, 2019, and the related notes (collectively, the Consolidated Financial Statements). In our opinion, the Consolidated Financial Statements present fairly, in all material respects, the financial position of the Company as of December 31, 2019, and the results of its operations and its cash flows for each of the years in the two-year period ended December 31, 2019, in conformity with U.S. generally accepted accounting principles.

Change in Accounting Principle

As discussed in Note 1 to the Consolidated Financial Statements, the Company has changed its method of accounting for leases as of January 1, 2019, in accordance with the adoption of Accounting Standards Codification (ASC) Topic 842, Leases. Our opinion is not modified with respect to this matter.

Basis for Opinion

These Consolidated Financial Statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these Consolidated Financial Statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (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 and in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the Consolidated 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 Consolidated Financial Statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included 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 Consolidated Financial Statements. We believe that our audits provide a reasonable basis for our opinion.

We have served as the Company’s auditor since 2012.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 1. Summary of Significant Accounting Policies

A.Organization

Leonardo DRS, Inc., together with its wholly owned subsidiaries (hereinafter, “DRS,” “the Company,” “us,” “our,” or “we”) is a supplier of defense electronics products, systems and military support services. The Company is controlled by Leonardo S.p.A (hereinafter, “Leonardo S.p.A.,” “the Parent”), an Italian multi-national aerospace, defense and security company headquartered in Rome, Italy, through its direct sole ownership of Leonardo US Holding, Inc. (“US Holding”). US Holding is the direct and sole shareholder of the Company.

DRS is a provider of defense products and technologies that are used across land, air, sea, space and cyber domains. Our diverse array of defense systems and solutions are offered to all branches of the U.S. military, major aerospace and defense prime contractors, government intelligence agencies, international military customers and industrial markets for deployment on a wide range of military platforms. We focus our capabilities in areas of critical importance to the U.S. military, such as soldier sensing, electronic warfare (“EW”), cyber security, network computing, communications, force protection and electrical power conversion and propulsion.

These capabilities directly align with our three reportable segments: Advanced Sensor Technologies, Network Computing & Communications and Integrated Mission Systems. The U.S. Department of Defense (“DoD”) is our largest customer and accounts for approximately 89% of our total revenues as an end-user for the year ended December 31, 2019. Specific international and commercial market opportunities exist within these segments and make up approximately 10% of our total revenues for the year ended December 31, 2019. In these priority areas, we have distinguishing capabilities, core technologies and intellectual property that underlie our product portfolio, and that we believe provide us with a sustainable differentiation from our competitors. As such, the Company is comprised of three reportable segments, which reflects the way performance is assessed and resources are allocated by our Chief Executive Officer, who is our chief operating decision maker (“CODM”).

Advanced Sensor Technologies (“AST”)

The AST segment provides electro-optical sensor technologies, laser systems, EW systems and intelligence and surveillance solutions to U.S. military and intelligence community customers. Major solutions include ground vehicle targeting and surveillance sensors, including electro-optical and advanced detection systems. Our soldier sensing applications include infrared imaging solutions and precision targeting systems. Our infrared focal plane array foundry produces small sized cryogenically cooled and uncooled infrared sensors. Beyond the capabilities noted above, AST also provides aircraft training instrumentation equipment and high-performance radio frequency receivers and transceivers for U.S. and international customers. Our quantum cascade laser technology has promising military and commercial medical applications.

Network Computing & Communication (“NC&C”)

The NC&C segment provides defense electronics solutions across all domains of warfare. Our technologies and products can be integrated into legacy and new military platforms, end-to-end network communication systems, satellite services and cyber solutions. We are a provider of ruggedized computing platforms. For the U.S. Navy and its allies, we provide naval computing infrastructure, network and data distribution, radar and rugged naval control systems, which are present on all naval surface and subsurface combatant vessels. Our global communications network is a worldwide network of terrestrial and satellite bandwidth that ensures our customers’ data is secure and reliable.

F-8

LEONARDO DRS, INC.    

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

Integrated Mission Systems (“IMS”)

The IMS segment provides critical force protection, vehicle integration, transportation and logistics and electrical conversion and ship propulsion systems to the U.S. military. Our force protection systems protect service members and military assets from evolving threats and include solutions for counter-unmanned aerial systems, short-range air defense systems and active protection systems on ground vehicles. We have military transportation and logistics offerings and ground vehicle integration capabilities to support U.S. forces in a wide range of operational environments. For the U.S. Navy, we provide power conversion and propulsion systems for our nation’s shipbuilding programs, building on our history of providing power components and systems for naval combat vessels for three decades.

Other

The Company separately presents the unallocable costs associated with corporate functions and certain non-operating subsidiaries of the Company as Corporate & Eliminations.

See Note 17: Segment Information for further information regarding our business segments.

B.Basis of presentation

The accompanying Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and include the accounts of DRS, its wholly owned subsidiaries and its controlling interests. Interests in joint ventures that are controlled by the Company, or for which the Company is otherwise deemed to be the primary beneficiary, are consolidated. For joint ventures in which the Company does not have a controlling interest, but exerts significant influence, the Company applies the equity method of accounting. All intercompany transactions and balances have been eliminated in consolidation.

C.Use of estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. The most significant of these estimates and assumptions relate to the recognition of contract revenues and estimated costs to complete contracts in process, recoverability of reported amounts of goodwill, long-lived assets and intangible assets, valuation of pensions and other postretirement benefits, the valuation of deferred tax assets and liabilities and the valuation of unrecognized tax benefits. Actual results could differ from these estimates.

D.Revenue Recognition

On January 1, 2018, we adopted Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers, and the related amendments of Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 606, which supersedes most previous U.S. GAAP revenue recognition guidance. As of the date of adoption, we elected the practical expedient for contract modifications, which allows us to assume that the terms of the contract that existed at the beginning of the earliest period presented have been in place since the inception of the contract on the basis that it is not practical to separately evaluate the effects of all prior contract modifications). Our revenues consist of sales of products (tangible goods) and sales of services to customers. We recognize the majority of our revenue from contracts with customers using an over time, cost-to-cost method of accounting. On certain other contracts, primarily time and material (“T&M”) and cost-plus contracts, revenue is recognized using the right-to-invoice practical expedient as we are contractually able to bill our customer based on control transferred to the customer. See Note 2: Revenue from Contracts with Customers for additional information regarding revenue recognition.

F-9

LEONARDO DRS, INC.    

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

E.Cost of Revenues

Cost of revenues includes materials, labor and overhead costs incurred in the manufacturing, design, and provision of products and services sold in the period as well as warranty costs. Material costs include raw materials, purchased components and sub-assemblies, outside processing and inbound freight costs. Labor and overhead costs consist of direct and indirect manufacturing costs, including wages and fringe benefits, operating supplies, depreciation and amortization, occupancy costs, and purchasing, receiving and inspection costs.

F.Research and Development Expenses

We conduct research and development (“R&D”) activities using our own funds (referred to as company-funded R&D or independent research and development (“IR&D”)) and under contractual arrangements with our customers (referred to as customer-funded R&D) to enhance existing products and services and to develop future technologies. R&D costs include basic research, applied research, concept formulation studies, design, development, and related test activities. IR&D costs are allocated to customer contracts as part of the general and administrative overhead costs and generally recoverable on our customer contracts with the U.S. Government. Customer-funded R&D costs are charged directly to the related customer contract. Substantially all R&D costs are charged to cost of revenues as incurred. Company-funded R&D costs charged to cost of revenues totaled $31 million and $29 million in 2019 and 2018, respectively.

G.Foreign Currency

Significant transactions in foreign currencies are translated into U.S. dollars at the approximate prevailing rate at the time of the transaction. Foreign exchange transaction gains and losses in 2019 and 2018 were immaterial to the Company's results of operations. The operations of the Company's foreign subsidiaries are translated from the local (functional) currencies into U.S. dollars using weighted average rates of exchange during each monthly period. The rates of exchange at each balance sheet date are used for translating certain balance sheet accounts and gains or losses resulting from these translation adjustments are included in the accompanying Consolidated Balance Sheet as a component of other comprehensive earnings.

H.Cash and Cash Equivalents

Cash and cash equivalents include cash on hand, deposits with banks or other short-term, highly liquid investments with original maturities of three months or less.

I.Accounts Receivable

Accounts receivable consist of amounts billed and currently due from customers. When events or conditions indicate that amounts outstanding from customers may become uncollectible, an allowance is estimated and recorded. See Note 3: Accounts Receivable for additional information regarding accounts receivable.

J.Inventories

Inventories are recorded at the lower of cost (determined by either actual, weighted average or first-in, first-out methods) or net realizable value, and include direct production costs as well as indirect costs, such as factory overhead. The net realizable value is calculated as the expected sales price in the course of normal operations net of estimated costs to finish and sell the goods. See Note 4: Inventories for additional information regarding inventories.

K.Property, Plant and Equipment

Property, plant and equipment is carried at cost less accumulated depreciation. Depreciation is calculated on the straight-line method. The estimated useful lives of plant, machinery and equipment and

F-10

LEONARDO DRS, INC.    

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

building and building improvements generally range from 3 to 10 years and 15 to 40 years, respectively. Leasehold improvements are amortized over the shorter of the estimated useful life of the improvements or the remaining life of the lease.

When assets are retired or otherwise disposed of, the cost and related accumulated depreciation or amortization are removed from the Consolidated Balance Sheet, and the net gain or loss is included in the determination of net earnings. Maintenance and repairs are charged to operations as incurred and renewals and improvements are capitalized. See Note 5: Property, Plant and Equipment for additional information regarding property, plant and equipment.

L.Goodwill

On January 1, 2018, we early adopted ASU 2017-04, Intangibles ‐ Goodwill and Other (Topic 350), Simplifying the Test for Goodwill Impairment. The standard simplifies the measurement of goodwill impairment by eliminating the requirement that an entity compute the implied fair value of goodwill based on the fair values of its assets and liabilities to measure impairment. Instead, goodwill impairment will be measured as the difference between the fair value and the carrying value of the reporting unit. Goodwill represents the excess purchase price paid to acquire a business over the fair value of net assets acquired. Goodwill is assigned to reporting units and is reviewed for impairment at the reporting unit level on an annual basis, or whenever changes in circumstances indicate that the carrying amount may not be recoverable. A reporting unit is an operating segment, or one level below that operating segment (the component level) if discrete financial information is prepared and regularly reviewed by the segment manager. Two or more components of an operating segment may be aggregated and deemed a single reporting unit if the components have similar economic characteristics. Based upon the aggregation criteria the Company concluded it had seven reporting units at both December 31, 2019 and 2018.

The annual impairment test is typically performed after completion of the Company's annual financial operating plan, which occurs as of December 31. The Company uses quantitative assessments and qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value. If the optional qualitative assessment is performed (Step 0) and the Company concludes that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, an additional quantitative fair value test (Step 1) is performed. When performing the Step 1 goodwill impairment test, we compare the fair values of each of our reporting units to their respective carrying values. In order to compute the fair value of our reporting units, we primarily use the income approach based on the discounted cash flows that each reporting unit expects to generate in the future, consistent with our operating plans. Determining the fair value of our reporting units requires significant judgments, including the timing and amount of future cash flows, long-term growth rates, determination of the weighted-average cost of capital and terminal value assumptions. If, based on the quantitative fair value test, the Company concludes that the carrying value of the reporting unit exceeds its fair value, the Company will recognize a goodwill impairment loss in an amount equal to that excess. The Company completed impairment tests as of December 31, 2019 and 2018 and no adjustment to the carrying value of goodwill was deemed to be necessary. See Note 7: Goodwill for additional information regarding goodwill.

M.Long-Lived Assets and Acquired Identifiable Intangible Assets

Identifiable intangible assets represent assets acquired as part of the Company's business acquisitions and include customer and program/contract-related assets. The values assigned to acquired identifiable intangible assets are determined as of the date of acquisition based on estimates and judgments regarding expectations for the estimated future after-tax cash flows from those assets over their lives, including the probability of expected future contract renewals and revenues, all of which are discounted to present value.

The Company assesses the recoverability of the carrying value of its long-lived assets and intangible assets with finite useful lives whenever events or changes in circumstances indicate that the carrying

F-11

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

amount of the assets or asset group may not be recoverable. If there are any indicators of impairment present, the Company then evaluates the recoverability of the potentially impaired long-lived assets and acquired identifiable intangible assets based upon expectations of undiscounted net cash flows from such assets. If the sum of the expected future undiscounted net cash flows is less than the carrying amount of the asset or asset group, a loss is recognized for the difference between the estimated fair value and the carrying amount of the assets. Assets to be disposed of, including those of discontinued operations, are reported at the lower of the carrying amount or fair value, less the costs to sell. See Note 5: Property, Plant and Equipment and Note 8: Intangible Assets for additional information regarding long-lived assets and intangible assets.

N.Derivative Financial Instruments

The Company does not use derivative financial instruments for trading purposes. All derivative instruments are carried on the Consolidated Balance Sheet as either assets or liabilities at fair value. The classification of gains and losses resulting from changes in the fair values of derivatives depends on the intended use of the derivative and its resultant designation. The Company had no significant derivative or hedging instruments during the years ended December 31, 2019 or 2018.

O.Pension and Other Postretirement Benefits

On January 1, 2018, we adopted ASU 2017-07, Compensation-Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. This ASU requires the service cost component of the net periodic costs for pension and postretirement plans to be presented in the same line item in the Consolidated Statements of Earnings as other employee-related compensation costs. The non-service related costs are required to be presented separately from the service cost component. The new standard also added guidance requiring entities to exclude these non-service related costs from capitalization in inventory or other internally-developed assets on a prospective basis, which did not have a significant effect.

The obligations for the Company's pension plans and postretirement benefit plans and the related annual costs of employee benefits are calculated based on several long-term assumptions, including discount rates for employee benefit liabilities, rates of return on plan assets, expected annual rates of salary increases for employee participants in the case of pension plans and expected annual increases in the costs of medical and other health care benefits in the case of postretirement benefit plans. These long-term assumptions are subject to revision based on changes in interest rates, financial market conditions, expected versus actual returns on plan assets, participant mortality rates and other actuarial assumptions, including future rates of salary increases, benefit formulas and levels, and rates of increase in the costs of benefits. Changes in these assumptions, if significant, can materially affect the amount of annual net periodic benefit costs recognized in the Company's results of operations from one year to the next, the liabilities for the pension plans and postretirement benefit plans and the Company's annual cash requirements to fund these plans. See Note 12: Pension and Other Postretirement Benefits for further information regarding our pension and postretirement plans.

P.Income Taxes

We and US Holding have entered into a Tax Allocation Agreement (“Tax Allocation Agreement”), dated as of November 16, 2020, with members of an affiliated group, as defined in Section 1504(a) of the U.S. Internal Revenue Code of 1986, as amended (the “Tax Code”), members of one or more consolidated, combined, unitary or similar state tax groups and additional parties who are part of an “expanded affiliated group” for certain tax purposes, prior to this offering. The agreement provides for the method of computing and allocating the consolidated U.S. federal tax liability of the affiliated group among its members and of allocating any state group tax liabilities among the state members for the taxable year ending December 31, 2020 and each subsequent year in which the parties are members of a group (whether federal or state). The agreement also provides for reimbursement of US Holding and/or DRS for payment of such tax liabilities, for compensation of any member for use of its “net operating loss” or “tax

F-12

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

credits” in arriving at such tax liabilities and the allocation and payment of any refund arising from a carryback of net operating losses or tax credits from subsequent taxable years. Under the agreement, the parties have agreed to calculate and allocate their respective tax liabilities and other tax attributes for taxable years beginning with the first consolidated taxable year that included DRS (i.e., the taxable year ended December 31, 2008) as if the agreement was then in effect.

The provision for income taxes is determined using the asset and liability approach of accounting for income taxes. Under this approach, deferred taxes represent the future tax consequences expected to occur when the reported amounts of assets and liabilities are recovered or paid. Income taxes as presented attribute deferred income taxes of US Holding to DRS in a manner that is systematic, rational and consistent with the asset and liability method and the governing Tax Allocation Agreement which allocates the tax liability amongst the entities, including DRS.

The provision for income taxes represents income taxes paid or payable for the current year plus the change in deferred taxes during the year. Deferred taxes result from differences between the financial and tax basis of DRS’ assets and liabilities and are adjusted for changes in tax rates and tax laws when such changes are enacted.

In general, the taxable income of DRS is included in the consolidated U.S. federal and state tax returns of US Holding. Where applicable, US Holding’s current portion of U.S. federal income taxes payable were offset against DRS’ net operating loss carryforwards in the period the related tax expense was recorded. Consequently, our net operating loss carryforwards are deemed to have been settled with US Holding in each year in an amount commensurate with the carrying value of the tax effected net operating loss utilized.

If management determines that some portion or all of a deferred tax asset is not “more likely than not” to be realized, a valuation allowance is recorded as a component of the income tax provision to reduce the deferred tax asset to the amounts expected to be realized. In determining whether the Company’s deferred tax assets are realizable, management considers all evidence, both positive and negative, including the history of financial reporting earnings, existing taxable temporary differences and their projected reversals, as well as projected future income and tax planning strategies. We believe it is more likely than not that we will generate sufficient taxable income in future periods to realize our deferred tax assets, subject to the valuation allowances recognized.

The Company assesses its tax positions for all periods open to examination by tax authorities based on the latest available information. Those positions are evaluated to determine whether they will more likely than not be sustained upon examination by the relevant taxing authorities. Liabilities for unrecognized tax benefits are measured based on the largest amount of benefit that is greater than 50% likely of being realized upon ultimate settlement. These unrecognized tax benefits are recorded as a component of income tax expense. Interest and penalties related to unrecognized tax benefits are not material.

During 2017 the Company early adopted ASU 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income" ("ASU 2018-02"). The standard allows companies to reclassify stranded tax effects in accumulated other comprehensive earnings (loss) that have been caused by the Tax Cuts and Jobs Act of 2017 (the “TCJA”) to retained earnings for each period in which the effect of the change in the U.S. federal corporate income tax rate is recorded. The Company has elected this option and has reclassified the stranded tax effects caused by the TCJA.

See Note 10: Income Taxes for additional information regarding income taxes.

Q.Earnings Per Share

Basic earnings per share (“EPS”) is computed by dividing net earnings by the weighted average number of shares of common stock outstanding during each period. The computation of diluted EPS

F-13

LEONARDO DRS, INC.    

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

includes the dilutive effect of outstanding stock-based compensation awards, only in periods in which such effect would have been dilutive for the period. As of December 31, 2019 and 2018 there were 100 basic and diluted common shares outstanding.

R.Fair Value Measurements

Fair value is the price the Company would receive to sell an asset or pay to transfer a liability in an orderly transaction with a market participant on the measurement date. We are required to maximize the use of observable inputs and minimize the use of unobservable inputs in measuring fair value, and to utilize a three-level fair value hierarchy that prioritizes the inputs used to measure fair value. The three hierarchical levels used to measure fair value are as follows:

Level 1 — Quoted prices in active markets for identical assets or liabilities.

Level 2 — Quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; and inputs other than quoted prices that are directly or indirectly observable.

Level 3 — Significant inputs to the valuation model are unobservable.

In certain instances, fair value is determined through information obtained from third parties using the latest available market data. In obtaining such data from third parties, we have evaluated the methodologies used to develop the estimate of fair value in order to assess whether such valuations are representative of fair value. The Company categorizes plan assets for disclosure purposes in accordance with this fair value hierarchy. Certain plan investments are measured at fair value using the net asset value (“NAV”) per share (or its equivalent) practical expedient and are therefore not categorized as Level 1, 2, or 3. NAV is defined as the total value of the fund divided by the number of the fund’s shares outstanding. See Note 12: Pension and Other Postretirement Benefits for further information regarding our pension and postretirement plans.

S.Financial Instruments

Our financial instruments consist primarily of cash and cash equivalents, accounts receivable, accounts payable and accrued expenses and other current liabilities. Financial instruments are reported in the Consolidated Balance Sheet at carrying value, which other than the 7.5% Term loan due November 30, 2022 approximate fair value. See Note 11: Debt for further information regarding our debt.

T.Acquisitions, Investments and Variable Interest Entities

Acquisitions

Our consolidated financial statements include the operations of acquired businesses from the date of acquisition. We account for acquired businesses using the acquisition method of accounting, which requires that any assets acquired and liabilities assumed be measured at their respective fair values on the acquisition date. The accounting for business combinations requires the Company to make significant judgments and estimates. Any excess of the fair value of consideration transferred over the assigned values of the net assets acquired is recognized as goodwill.

There were no significant acquisitions that were completed for the years ended December 31, 2019 and 2018.

Investments

Investments where we have the ability to exercise significant influence, but do not control, are accounted for under the equity method of accounting and are included in other noncurrent assets on our Consolidated Balance Sheet. Significant influence typically exists if we have a 20% to 50% ownership interest in the investee. Under this method of accounting, our share of the net earnings or losses of the

F-14

LEONARDO DRS, INC.    

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

investee is included in operating profit in other income, net on our Consolidated Statements of Earnings since the activities of the investee are closely aligned with the operations of the business segment holding the investment. We evaluate our equity method investments for impairment whenever events or changes in circumstances indicate that the carrying amounts of such investments may be impaired. If a decline in the value of an equity method investment is determined to be other than temporary, a loss is therefore recorded during the current period. See Note 13: Equity Method Investments for further information regarding our equity method investments.

Variable Interest Entities

The Company occasionally forms joint ventures and/or enters into arrangements with special purpose limited liability companies for the purpose of bidding and executing on specific projects. The Company analyzes each such arrangement to determine whether it represents a variable interest entity (“VIE”). If the arrangement is determined to be a VIE, the Company assesses whether it is the primary beneficiary of the VIE and if it is, consequently required to consolidate the VIE. The Company did not have any investment in VIEs as of December 31, 2019 or 2018.

U.New Accounting Pronouncements

Recently Adopted Accounting Pronouncements

Leases

Effective January 1, 2019, the Company adopted ASU 2016-02, Leases (Topic 842), as amended (“ASC 842”), which requires lessees to recognize most leases on their balance sheets as right-of-use (“ROU”) assets along with corresponding lease liabilities. The new standard requires lessees to apply a dual approach, classifying leases as either finance or operating leases. This classification determines whether lease expense is recognized based on an effective interest method or on a straight-line basis over the term of the lease. The new standard also requires increased disclosures to help financial statement users better understand the amount, timing and uncertainty of cash flows arising from leases. ASC 842 provides companies with the option to elect an optional transition method whereby companies apply the standard to new and existing leases within the scope of the guidance as of the beginning of the period of adoption. We elected this transition method and have recognized ROU assets, lease liabilities and any cumulative-effect adjustments to the opening balance of accumulated deficit as of January 1, 2019. Prior period amounts were not adjusted and will continue to be reported under the accounting standards in effect for those periods. As part of our adoption, we elected to utilize the practical expedients provided which permitted us to not reassess our previous conclusions on lease identification, lease classification and the accounting for initial direct costs for any existing leases. We did not elect the hindsight practical expedient.

The adoption of the new standard resulted in the recognition of lease assets and lease liabilities of $158 million and $172 million, respectively, on the Consolidated Balance Sheet with no adjustment to our January 1, 2019 beginning accumulated deficit balance. The difference between the right of use asset and lease liability primarily relates to deferred rent recorded prior to adoption. The adoption of the new standard did not have a material impact on our results of operations or cash flows. 

Accounting Guidance Issued but Not Yet Adopted as of December 31, 2019:

Financial Instruments - Credit Losses

In June 2016, the FASB issued ASU 2016‐13, Financial Instruments ‐ Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments, as amended. The standard requires a change in the measurement approach for credit losses on financial assets measured on an amortized cost basis from an incurred loss method to an expected loss method, thereby eliminating the requirement that a credit loss be considered probable to impact the valuation of a financial asset measured on an amortized cost basis. The standard requires the measurement of expected credit losses to be based on relevant

F-15

LEONARDO DRS, INC.    

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

information about past events, including historical experience, current conditions and a reasonable and supportable forecast that affects the collectability of the related financial asset. The standard is effective for fiscal years beginning after December 15, 2019, with early adoption permitted. The Company does not expect the adoption to have a material impact on our operating results, financial position or cash flows.

Changes to Disclosure Requirements for Defined Benefit Plans

In August 2018, the FASB issued ASU 2018-14, Compensation - Retirement Benefits - Defined Benefit Plans - General (Subtopic 715-20): Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans. Specifically, the amendment removes disclosure requirements for amounts classified in accumulated other comprehensive income expected to be recognized over the next year and the effects of a one-percentage-point change in the assumed health care cost trend rate on service cost, interest cost and the benefit obligation for postretirement benefits. The amendment also requires additional disclosure around weighted-average interest crediting rates for cash balance plans, a narrative description of the reasons for significant gains and losses, and an explanation of any other significant changes in the benefit obligation or plan assets. The standard is effective for fiscal years beginning after December 15, 2020, with early adoption permitted. The Company does not expect the adoption to have a material impact on our disclosures.

Simplifying the Accounting for Income Taxes

In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes which removes certain exceptions to the general principles in Topic 740 for: recognizing deferred taxes for investments, performing intra-period allocations and calculating taxes in interim periods. The amendments also improve consistent application of and simplify U.S. GAAP for other areas of Topic 740 by clarifying and amending existing guidance. The standard is effective for fiscal years beginning after December 15, 2020. The Company plans to adopt the standard as of January 1, 2021 and is currently evaluating this guidance to determine the impact it may have on our Consolidated Financial Statements.

Note 2. Revenue from Contracts with Customers

The Company recognizes revenue for each separately identifiable performance obligation in a contract representing an obligation to transfer a distinct good or service to a customer. In most cases, goods and services provided under the Company’s contracts are accounted for as single performance obligations due to the complex and integrated nature of our products and services. These contracts generally require significant integration of a group of goods and/or services to deliver a combined output. In some contracts, the Company provides multiple distinct goods or services to a customer. In those cases, the Company accounts for the distinct contract deliverables as separate performance obligations and allocates the transaction price to each performance obligation based on its relative standalone selling price, which is generally estimated using cost plus a reasonable margin. We classify revenues as products or services on our Consolidated Statements of Earnings based on the predominant attributes of the performance obligations. While the Company provides warranties on certain contracts, we typically do not provide for services beyond standard assurances and therefore do not consider warranties to be separate performance obligations. Typically we enter into three types of contracts: fixed-price contracts, cost-plus contracts and T&M contracts (cost-plus contracts and T&M contracts are aggregated below as flexibly priced contracts). The majority of our total revenues are derived from fixed-price contracts; refer to the revenue disaggregation disclosures that follow.

For fixed-price contracts, customers agree to pay a fixed amount, negotiated in advanced for a specified scope of work.

For cost-plus contracts typically we are reimbursed for allowable or otherwise defined total costs (defined as cost of revenues plus allowable general and administrative expenses) incurred, plus a fee. The contracts may also include incentives for various performance criteria, including quality, timeliness and cost-effectiveness. In addition, costs are generally subject to review by clients and regulatory audit

F-16

LEONARDO DRS, INC.    

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

agencies, and such reviews could result in costs being disputed as non-reimbursable under the terms of the contract.

T&M contracts provide for reimbursement of labor hours expended at a contractual fixed labor rate per hour, plus the actual costs of material and other direct non-labor costs. The fixed labor rates on T&M contracts include amounts for the cost of direct labor, indirect contract costs and profit.

Estimating the transaction price for an arrangement requires judgment and is based on expected results which are determined using the Company’s historical data. We estimate that the revenue that we expect to be entitled to receive from a customer to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur.

Revenue from contracts with customers is recognized when the performance obligations are satisfied through the transfer of control over the good or service to the customer, which may occur either over time or at a point in time.

Revenues for the majority of our contracts are measured as determined by the ratio of cumulative costs incurred to date to estimated total contract costs at completion (the "cost-to-cost method"). We believe this is an appropriate measure of progress toward satisfaction of performance obligations as this measure most accurately depicts the progress of our work and transfer of control to our customers. Due to the long-term nature of many of our contracts, developing the estimated total cost at completion and total transaction price often requires judgment. Factors that must be considered in estimating the cost of the work to be completed include the nature and complexity of the work to be performed, subcontractor performance and the risk and impact of delayed performance.

After establishing the estimated total cost at completion, we follow a standard Estimate at Completion (“EAC”) process in which we review the progress and performance on our ongoing contracts at least quarterly. Adjustments to original estimates for a contract's revenue, estimated costs at completion and estimated profit or loss often are required as work progresses under a contract, as experience is gained and as more information is obtained, even though the scope of work required under the contract may not change and are also required if contract modifications occur. When adjustments in estimated total costs at completion or in estimated total transaction price are determined, the related impact on revenue and operating income are recognized using the cumulative catch-up method, which recognizes in the current period the cumulative effect of such adjustments for all prior periods. Any anticipated losses on these contracts are fully recognized in the period in which the losses become evident.

EAC adjustments had the following impacts to revenue for the periods presented:

	Year Ended December 31,
(Dollars in millions)	2019			2018
Revenue	$	(55)		$	(26)
Total % of Revenue	2		%	1		%

The impacts noted above are attributed primarily to changes in our firm-fixed-price development type programs. As changes happen in the design required to achieve contractual specifications, those changes often result in changes in estimate and related profitability of the programs. The reductions to revenue for the years ended December 31, 2019 and 2018 were related to certain masted surveillance and submarine electronic propulsion programs within our IMS segment.

Conversely, if the requirements for the recognition of contracts over time are not met, revenue is recognized at a point in time when control transfers to the customer, which is generally upon transfer of title. In such cases, the production that is in progress and costs that will be recognized at a future point in time are reported within "inventories".

F-17

LEONARDO DRS, INC.    

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

Costs to obtain a contract are incremental direct costs incurred to obtain a contract with a customer, including sales commissions and dealer fees, and are capitalized if material. Costs to fulfill a contract include costs directly related to a contract or specific anticipated contract (e.g., certain design costs) that generate or enhance our ability to satisfy our performance obligations under these contracts. These costs are capitalized to the extent they are expected to be recovered from the associated contract. Capitalized costs to obtain or fulfill a contract are amortized to expense over the expected period of benefit for contracts with terms greater than one year on a systematic basis that is consistent with the pattern of transfer of the associated goods and services to the customer.

Contract Assets and Liabilities

The timing of revenue recognition, billings and cash collections results in billed accounts receivable, unbilled receivables (contract assets), and customer advances and deposits (contract liabilities) on the Consolidated Balance Sheet. Amounts are billed as work progresses in accordance with agreed-upon contractual terms, either at periodic intervals (e.g., biweekly or monthly) or upon achievement of contractual milestones. Generally, billing occurs subsequent to revenue recognition, resulting in contract assets. However, we sometimes receive advances or deposits from our customers before revenue is recognized, resulting in contract liabilities.

(Dollars in millions)	December 31, 2019
Contract assets	$	736
Contract liabilities	175
Net contract assets	$	561

Revenue recognized in 2019 that was included in the contract liability balance at the beginning of the year was $62 million.

The change in the balances of the Company’s contract assets and liabilities primarily results from timing differences between revenue recognition and customer billings and/or payments.

Contract assets related to amounts withheld by customers until contract completion are not considered a significant financing component of our contracts because the intent is to protect the customers from our failure to satisfactorily complete our performance obligations. Payments received from customers in advance of revenue recognition (contract liabilities) are not considered a significant financing component of our contracts because they are utilized to pay for contract costs within a one-year period or are requested by us to ensure the customers meet their payment obligations.

Value of Remaining Performance Obligations

The value of remaining performance obligations, which we also refer to as total backlog, includes the following components:

•Funded - Funded backlog represents the revenue value of orders for services under existing contracts for which funding is appropriated or otherwise authorized less revenue previously recognized on these contracts.

•Unfunded - Unfunded backlog represents the revenue value of orders for services under existing contracts for which DRS has not been authorized with contract funding less revenue previously recognized on these contracts.

In performing the annual goodwill impairment tests as of December 31, 2019 and 2018, the Company determined that the fair value of all of its reporting units exceeded their carrying values. As such, no impairments were recognized.

Note 8. Intangible Assets

Other intangible assets mainly refer to the fair value of existing customer contractual relationships attributable to the acquired business and patents which are being amortized over their respective lives. The fair value of intangible assets typically is determined, as of the date of acquisition, based on estimates and judgments regarding expectations for the estimated future after-tax earnings and cash flows (including cash flows for working capital) arising from backlog and follow-on sales to the customer over their estimated lives, including the probability of expected future contract renewals and sales, less a contributory assets charge, all of which is discounted to present value.

The following disclosure presents certain information regarding the Company's intangible assets as of December 31, 2019. All intangible assets are being amortized over their estimated useful lives, as indicated below, with no estimated residual values.

Note 9. Leases

The Company leases various real estate for manufacturing facilities, administrative offices and warehouses under both finance leases and operating leases. In addition, the Company leases vehicles, machinery and office equipment under operating leases. We determine whether our contracts are or contain a lease at the inception of such arrangements. A contract is or contains a lease if it conveys the right to control the use of an identified asset for a period of time in exchange for consideration.

ROU assets and lease liabilities are recorded on the Consolidated Balance Sheet as of the lease commencement based on the present value of the future lease payments over the lease term. As our leases do not generally explicitly state the discount rate implicit in the lease, we use our incremental borrowing rate, which is determined based on the rate of interest that the Company would have to pay to borrow an amount equal to the lease payments on a collateralized basis over a similar term as of the lease commencement date. In addition to the present value of the future lease payments, the calculation of the ROU asset also includes lease payments made at or before the commencement date of the lease, less any lease incentives received. The remaining lease cost is amortized over the remaining life of the lease on a straight-line basis. We evaluate ROU assets for impairment consistent with the treatment of other long-lived assets.

Some of our leases include options to extend the lease terms or to terminate the lease early. We include the impact of the option in the determination of the ROU assets and liabilities when it is reasonably certain that we will exercise the option. Our lease payments are largely fixed, but may include variable payments that do not depend on an index or rate, such as usage-based amounts, and are recorded as a lease expense in the period incurred. The Company’s lease agreements do not contain any material residual value guarantees or restrictive covenants.

In 2019, we have entered into a sale-leaseback transaction related to a facility in Milwaukee, WI. We have analyzed the transaction and determined the criteria to recognize a sale has been met and we have derecognized the related assets. The arrangement does not contain a repurchase option or other substantive obligations related to the property. Further, we have determined that the underlying lease

F-23

LEONARDO DRS, INC.    

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

meets the criteria to be classified as an operating lease. As a result, we have recognized an immaterial loss, related to the transaction.

We elected not to recognize a ROU asset and lease liability for leases with an initial term of 12 months or less. These leases are expensed on a straight-line basis over the lease term.The Company elected the practical expedient to not separate lease and non-lease components and to instead account for them as a single component. We have elected this practical expedient for all classes of assets.

As of December 31, 2019, we have two significant lease agreements related to new facilities in Milwaukee, WI and St. Louis, MO that have been executed but not yet commenced. The leases commenced during 2020.

See Note 12: Pension and Other Postretirement Benefits for additional details. As of December 31, 2019 the Company had U.S. federal net operating loss carryforwards of $246 million which we anticipate we will be able to apply prior to their expiration which commences in 2025. The annual utilization of approximately $34 million of our Federal net operating losses is subject to limitations under section 382 of the Internal Revenue Code. As of December 31, 2019 we had apportioned state net operating loss carryforwards of $325 million substantially all of which are associated with jurisdictions in which we currently file and the Company expect to utilize prior to expiration. We have federal tax credit carryforwards that commence expiring in 2032, which we anticipate being able to utilize prior to their expiration.

Tax Uncertainties

The Company maintains reserves for uncertain tax positions related to unrecognized income tax benefits. These reserves involve considerable judgment and estimation and are evaluated by management at least quarterly based on the best information available. The Company’s total liability for unrecognized tax benefits as of December 31, 2019 and 2018 was approximately $18 million and $14 million, respectively; all of which will impact the effective tax rate when recognized. Approximately $16 million and $12 million as of December 31, 2019 and 2018, respectively, have been recorded within (and as an offset to) deferred tax assets. In addition, the Company does not believe there are any tax positions

F-28

for which it is reasonably possible that the unrecognized tax benefits will vary significantly over the next 12 months. The table below summarizes the activity associated with our unrecognized tax benefits:

The Company is subject to U.S. federal income tax as well as income tax of multiple state and foreign jurisdictions. The Company has substantially concluded all U.S. federal income tax matters for years through the tax year ended December 31, 2016 except as it relates to the net operating loss carryforward and tax credit carryforwards. Substantially all material state and local matters have been concluded for years through the tax year ended December 31, 2015. The Company has substantially concluded all material tax matters in foreign jurisdictions for years through the tax years ending during 2016. Management does not believe it is reasonably possible that any reduction in the unrecognized tax benefit will occur within the next 12 months. We classify our unrecognized tax benefits as well as accrued penalties and interest as noncurrent liabilities.

As of December 31, 2019, the Company has accumulated undistributed earnings generated by our foreign subsidiaries and most have been taxed in the U.S. as a result of the 2017 TCJA. The 2017 TCJA allows for a dividend received deduction for repatriation of foreign earnings. We intend to indefinitely reinvest these earnings. Should the Company’s undistributed earnings from its investment in non‐U.S. subsidiaries be distributed in the future in the form of dividends or otherwise, the Company may be subject to foreign and domestic income taxes and withholding taxes.

Term Loans

In January 2009, the Company entered into a credit agreement with its ultimate parent company, Finmeccanica S.p.A. (presently Leonardo S.p.A.) in the amount of $2 billion (the “Credit Agreement”). The

F-29

LEONARDO DRS, INC.    

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

Credit Agreement was subsequently assigned to US Holding and has a maturity of November 30, 2022. The Credit Agreement provides for a term loan bearing interest at a rate of 7.5%, with interest payments due semi-annually on June 20 and December 20 in each year (the “7.5% Term loan”). The outstanding balance of the 7.5% Term loan at December 31, 2019 was $439 million. The fair value of this term loan at December 31, 2019 was $537 million; however the Company has the ability to prepay the outstanding principal balance at the carrying amount without penalty.

In June 2017, the Company entered into an unsecured term loan with US Holding in the principal amount of $137.5 million, the proceeds of which were used to finance the acquisition of Daylight Solutions. The Daylight Term Loan had an outstanding balance of $113 million at December 31, 2019, which approximates its fair value. The Daylight Term Loan matures on October 15, 2024. The Daylight Term Loan has an interest rate of 5.0%, with interest payments due semi-annually on April 15 and October 15.

During April 2018, the Company was advanced an additional $50 million by US Holding under a term loan. This term loan bears interest at 4.0% and had an initial maturity date of December 31, 2018, which was extended until December 31, 2021. The outstanding balance of the 4.0% term loan at December 31, 2019 was $50 million, which approximates its fair value.

Credit Facilities

The Credit Agreement provides for a revolving credit facility available for working capital needs of the Company (the “Revolving Credit Facility”). As of December 31, 2019, the Revolving Credit Facility had a credit limit of $350 million and an interest rate of LIBOR plus 3.5%. There is a commitment fee of 0.25% applied to the unused balance of the Revolving Credit Facility and there are no compensating balance requirements. There was no balance on the Revolving Credit Facility as of December 31, 2019.

The Company also maintains uncommitted working capital credit facilities with certain financial institutions in the aggregate of $65 million at December 31, 2019 (the “Financial Institution Credit Facilities”). The Financial Institution Credit Facilities are guaranteed by Leonardo S.p.A. The primary purpose of the Financial Institution Credit Facilities is to support standby letter of credit issuances on contracts with customers and also includes a revolver with a maximum borrowing limit of $15 million, which bears interest at LIBOR plus 0.5%. At December 31, 2019, there was no balance outstanding on the revolver. The Company has letters of credit outstanding of approximately $30 million as of December 31, 2019, which reduces the available capacity of the Financial Institution Credit Facilities by an equal amount.

Short-Term Borrowings

As of December 31, 2019, the Company recognized $38 million collected on behalf of the buyers of our trade receivables pursuant to our factoring arrangements as short-term borrowings and current portion of long-term debt in the Consolidated Balance Sheet, which approximates its fair value. Refer to Note 3: Accounts Receivable for more information.

Interest Paid

Total interest paid associated with our debt was $65 million and $58 million in 2019 and 2018, respectively.

Note 12. Pension and Other Postretirement Benefits

Retirement Plan Summary Information

The Company maintains multiple pension plans, both contributory and non-contributory, covering employees at certain locations. Eligibility requirements for participation in the plans vary, and benefits generally are based on the participant's compensation and years of service, as defined in the respective plan. The Company's funding policy generally is to contribute in accordance with cost accounting standards that affect government contractors, subject to the Tax Code and regulations thereunder. Plan assets are invested primarily in equities, bonds (both corporate and U.S. government), U.S. government-sponsored entity instruments, cash and cash equivalents and real estate.

The Company also provides postretirement medical benefits for certain retired employees and dependents at certain locations. Participants are eligible for these benefits when they retire from active service and meet the eligibility requirements for the Company's postretirement benefit plans. The Company's contractual arrangements with the U.S. government provide for the recovery of contributions to a Voluntary Employees' Beneficiary Association (“VEBA”) trust and, for non-funded plans, recovery of claims on a pay-as-you-go basis, subject to the Tax Code and regulations thereunder, with the retiree generally paying a portion of the costs through contributions, deductibles and coinsurance provisions.

The Company also maintains certain non-contributory and unfunded supplemental retirement plans. Eligibility for participation in the supplemental retirement plans is limited, and benefits generally are based on the participant's compensation and/or years of service.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

The expected long-term return on plan assets assumption represents the average rate that the Company expects to earn over the long-term on the assets of the Company's benefit plans, including those from dividends, interest income and capital appreciation. The assumption has been determined based on expectations regarding future rates of return for the plans' investment portfolio, with consideration given to the allocation of investments by asset class and historical rates of return for each individual asset class.

A one percentage increase or decrease in healthcare trend rates in the table above would have an insignificant impact to our service and interest cost and the postretirement medical obligations.

Plan Assets

The Company is responsible for formulating the investment policies and strategies for each plan's assets. Presently all of the plans are governed by a single investment policy and are uniformly invested. As part of the policy statement the Company has implemented a glide path which adjusts the percentage of assets invested in return seeking assets based upon the attainment of specific funding percentages. The non-return seeking assets are invested primarily in bonds with maturities closely matching the anticipated payment of benefits.

The table below represents all of the Company's funded pension plans' and postretirement benefit plans' weighted-average asset allocation at December 31, 2019 by asset category:

	Asset Allocation
	2019
Asset Category
Equity securities	49	%
Debt securities	40	%
Real estate	6	%
Other, primarily cash and cash equivalents, and hedge funds	5	%

The table below presents the target allocation ranges for each major asset category for the Company's benefit plans for the year ended December 31, 2019.

	Target Asset Allocation Range
Asset Category
Equity securities	40% - 60%
Debt securities	40% - 50%
Real estate	5% - 10%

For the year ended December 31, 2020, the Company expects to contribute $5 million to its pension plans and an inconsequential amount to its postretirement plans. The Company deferred approximately $8 million in pension contributions until 2021 under the CARES Act and IRS Notice 2020-82.

Defined Contribution Plans

Note 14. Share-based compensation plans

The Company does not have any share-based compensation plans. See Note 6: Other Liabilities, for information regarding cash compensation.

Note 15. Commitments and Contingencies

Commitments

The Company’s commitments are primarily related to our lease and credit agreements. See Note 9: Leases and Note 11: Debt for additional information on our leases and credit agreements.

Contingencies

From time to time we are subject to certain legal proceedings and claims in the ordinary course of business. These matters are subject to many uncertainties and it is possible that some of these matters ultimately could be decided, resolved or settled in a manner adverse to us. Although the precise amount of liability that may result from these matters is not ascertainable, the Company believes that any amounts exceeding the Company's recorded accruals should not materially adversely affect the Company's financial condition or liquidity. It is possible, however, that the ultimate resolution of those matters could result in a material adverse effect on the Company's results of operations and/or cash flows from operating activities for a particular reporting period. We establish reserves for specific legal matters when we determine that the likelihood of an unfavorable outcome is probable and the loss is reasonably estimable.

Some environmental laws, such as the Comprehensive Environmental Response, Compensation and Liability Act of 1980 (also known as “CERCLA” or the “Superfund law”) and similar state statutes, can impose liability upon former owners or operators for the entire cost of investigating and remediating contaminated sites regardless of the lawfulness of the original activities that led to the contamination. In July 2000, an entity which later became a subsidiary of the Company received a Section 104(e) Request for Information (“RFI”) from the National Park Service (“NPS”), pursuant to CERCLA, regarding the presence of radioactive material at a site within a national park, which site was operated by an alleged predecessor to our subsidiary over 50 years ago. Following the subsidiary’s response to the RFI, the NPS directed it and another alleged former operator to perform an Engineering Evaluation and Cost Analysis (“EE/CA”) of a portion of the site. The Company’s subsidiary made a good faith offer to conduct an alternative EE/CA work plan, but the NPS rejected this offer and opted to perform the EE/CA itself. The NPS previously posted its intention to open a formal public comment period regarding the EE/CA at the end of 2019. To the Company’s knowledge, the EE/CA has not been released and a public comment period has yet to be opened.

Following completion of the EE/CA, the NPS may seek reimbursement for its investigative and remedial efforts to date, or direct one or more of the potentially responsible parties to perform any remediation that may be required by CERCLA or may enter an alternative dispute resolution proceeding to attempt to resolve each party’s share. In addition, the NPS may seek to recover damages for loss of use of certain natural resources. The Company believes that it has legitimate defenses to its subsidiary’s potential liability and that there are other potentially responsible parties for the environmental conditions at the site, including the U.S. government as owner, operator and arranger at the site. The potential liability associated with this matter could change substantially due to such factors as additional information on the nature or extent of contamination, methods of remediation that might be recommended or required, changes in the apportionment of costs among the responsible parties, whether the NPS seeks to recover additional damages, whether the NPS’s plans to investigate additional areas to identify a need for further remedial action for which the Company may be identified as a potentially responsible party and other actions by governmental agencies or private parties.

The Company has recorded its best estimate of damages and its share of remediation costs related to the site to reflect what we and our advisors reasonably believe we would be liable for based on the

F-37

LEONARDO DRS, INC.    

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

current information and circumstances of the claim, exclusive of other potential liabilities that may be asserted in the future.

In the performance of our contracts we routinely request contract modifications that require additional funding from the customer. Most often, these requests are due to customer-directed changes in the scope of work. While we are entitled to recovery of these costs under our contracts, the administrative process with our customer may be protracted. Based on the circumstances, we periodically file requests for equitable adjustment (“REAs”) that are sometimes converted into claims. In some cases, these requests are disputed by our customer. We believe our outstanding modifications, REAs and other claims will be resolved without material impact to our results of operations, financial condition or cash flows.

As a government contractor, with customers including the U.S. government as well as various state and local government entities, the Company may be subject to audits, investigations and claims with respect to its contract performance, pricing, costs, cost allocations and procurement practices. Additionally, amounts billed under such contracts, including direct and indirect costs, are subject to potential adjustments before final settlement.

Management believes that adequate provisions for such potential audits, investigations, claims and contract adjustments, if any, have been made in the Consolidated Financial Statements.

Restructuring costs

In 2019 and 2018 we engaged in restructuring initiatives in order to rationalize headcount and align our operations in a more strategic and cost-efficient structure. In connection with these restructuring initiatives we recorded charges totaling $20 million and $14 million for the years ended December 31, 2019 and 2018, respectively. Costs incurred were related to employee termination and severance costs, as well as costs related to discontinuing product lines or closing down of locations. Charges were recorded within other operating expenses, net, with the exception of costs incurred related to the write-

Product Warranties

Product warranty costs generally are accrued in proportion to product revenue realized in conjunction with our over-time revenue recognition policy. Product warranty expense is recognized based on the term of the product warranty, generally one year to three years, and the related estimated costs, considering historical claims expense. Accrued warranty costs are reduced as these costs are incurred and as the warranty period expires, and otherwise may be modified as specific product performance issues are

Note 16. Related Party Transactions

Under our current proxy agreement DRS remains largely independent from the Parent. Additionally, the Company provides services related to the US interface for the Parent and its other affiliates. These services include financial, tax, trade compliance, marketing and communications and legal.

The Company also has related-party sales with the Parent and its other affiliates that occur in the regular course of business. Related-party sales for these transactions are included in revenues and were $16 million and $20 million for the years ended December 31, 2019 and 2018, respectively. The receivables and payables related to these transactions with the Parent and its other affiliates of $2 million and $10 million, respectively, are included in accounts receivable and accounts payable in the Company’s Consolidated Balance Sheet as of December 31, 2019.

The Company entered into a Surplus Treasury Agreement with US Holding (the “Surplus Agreement”) in December 2019. The Surplus Agreement allows the Company to advance excess funds to US Holding when funds are available. The advances bear interest at LIBOR plus between 5 and 20 basis points depending on the tenor of the advance. As of December 31, 2019, the Company had advanced $100.0 million to US Holding, which is presented on the balance sheet as a related party note receivable.

The Company entered into Tax Allocation Agreement with US Holding, dated as of November 16, 2020. Refer to Note 1:Summary of Significant Accounting Policies for more information.

Note 17. Segment Information

Operating segments represent components of an enterprise for which separate financial information is available that is regularly reviewed by the CODM in determining how to allocate resources and assess performance. Our Chief Executive Officer is our CODM and he uses a variety of measures to assess the performance of the Company as a whole, depending on the nature of the activity. The Company’s operating and reportable segments consist of AST, NC&C and IMS. All other operations, which consists primarily of DRS Corporate Headquarters and certain non-operating subsidiaries of the Company, are grouped in Corporate & Eliminations.

We primarily use Adjusted EBITDA to manage the Company and allocate resources. Adjusted EBITDA of our business segments includes our net earnings before income taxes, amortization of acquired intangible assets, depreciation, restructuring costs, interest, transaction costs related to this offering, acquisition and divestiture related expenses, foreign exchange, COVID-19 response costs, non-service pension expenditures and other one-time non-operational events. Adjusted EBITDA is used to facilitate a comparison of the ordinary, ongoing and customary course of our operations on a consistent basis from period to period and provide an additional understanding of factors and trends affecting our business segments. This measure assists the CODM in assessing segment operating performance consistently over time without the impact of our capital structure, asset base and items outside the control of the management team and expenses that do not relate to our core operations.

Certain information related to our segments for the years ended December 31, 2019 and 2018, is presented in the following tables. Consistent accounting policies have been applied by all segments within the Company, within all reporting periods. A description of our reportable segments as of

The Company has evaluated subsequent events through December 10, 2020, which represents the date on which the Consolidated Financial Statements were issued.

The coronavirus (“COVID-19”) pandemic has caused significant disruptions to national and global economies and government activities. We are designated as an essential business in each of the jurisdictions in which we operate and, as such, we have worked to ensure continuity of our operations to meet our contractual obligations. Certain of our businesses have experienced disruptions, such as customer site closures, travel restrictions and social distancing requirements. We have adopted various initiatives at our businesses as part of our business continuity programs, and we continue to work to mitigate risk when disruptions occur.

Item 14.Indemnification of Directors and Officers.

Leonardo DRS, Inc. Is Incorporated Under the Laws of the State of Delaware.

Section 145(a) of the DGCL provides that a corporation may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation) by reason of the fact that the person is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by the person in connection with such action, suit or proceeding if the person acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe the person’s conduct was unlawful.

Section 145(b) of the DGCL provides that a corporation may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the corporation to procure a judgment in its favor by reason of the fact that the person is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys’ fees) actually and reasonably incurred by the person in connection with the defense or settlement of such action or suit if the person acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of the corporation and except that no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to the corporation unless and only to the extent that the Delaware Court of Chancery or the court in which such action or suit was brought shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the Delaware Court of Chancery or such other court shall deem proper.

II-1

Section 145(c) of the DGCL provides that to the extent that a present or former director or officer of a corporation has been successful on the merits or otherwise in defense of any action, suit or proceeding referred to in subsections (a) and (b) of Section 145 of the DGCL, or in defense of any claim, issue or matter therein, such person shall be indemnified against expenses (including attorneys’ fees) actually and reasonably incurred by such person in connection therewith.

Section 145(e) of the DGCL provides that expenses (including attorneys’ fees) incurred by an officer or director of the corporation in defending any civil, criminal, administrative or investigative action, suit or proceeding may be paid by the corporation in advance of the final disposition of such action, suit or proceeding upon receipt of an undertaking by or on behalf of such director or officer to repay such amount if it shall ultimately be determined that such person is not entitled to be indemnified by the corporation as authorized in Section 145 of the DGCL. Such expenses (including attorneys’ fees) incurred by former directors and officers or other employees and agents of the corporation or by persons serving at the request of the corporation as directors, officers, employees or agents of another corporation, partnership, joint venture, trust or other enterprise may be so paid upon such terms and conditions, if any, as the corporation deems appropriate.

Section 145(g) of the DGCL specifically allows a Delaware corporation to purchase liability insurance on behalf of its directors and officers and to insure against potential liability of such directors and officers regardless of whether the corporation would have the power to indemnify such directors and officers under Section 145 of the DGCL.

Section 102(b)(7) of the DGCL permits a Delaware corporation to include a provision in its certificate of incorporation eliminating or limiting the personal liability of directors to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director. This provision, however, may not eliminate or limit a director’s liability (1) for breach of the director’s duty of loyalty to the corporation or its stockholders, (2) for acts or omissions not in good faith or involving intentional misconduct or a knowing violation of law, (3) under Section 174 of the DGCL, which provides for liability of directors for unlawful payments of dividends or unlawful stock purchases, redemptions or other distributions, or (4) for any transaction from which the director derived an improper personal benefit.

Section 174 of the DGCL provides, among other things, that a director who willfully and negligently approves of an unlawful payment of dividends or an unlawful stock purchase or redemption may be held liable for such actions. A director who was either absent when the unlawful actions were approved or dissented at the time may avoid liability by causing his or her dissent to such actions to be entered in the books containing the minutes of the meetings of the board of directors at the time the action occurred or immediately after the absent director receives notice of the unlawful acts.

Our amended and restated certificate of incorporation will contain provisions permitted under the DGCL relating to the liability of directors. These provisions will eliminate a director’s personal liability for monetary damages resulting from a breach of fiduciary duty, except in circumstances involving:

•any breach of the director’s duty of loyalty;

•acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of the law;

•unlawful payments of dividends or unlawful stock purchases, redemptions or other distributions; or

•any transaction from which the director derives an improper personal benefit.

Our amended and restated certificate of incorporation and our amended and restated by-laws will require us to indemnify and advance expenses to our directors and officers to the fullest extent not prohibited by the DGCL and other applicable law, except in the case of a proceeding instituted by the director without the approval of our board. Our amended and restated certificate of incorporation and our

II-2

amended and restated by-laws will provide that we are required to indemnify our directors and officers, to the fullest extent permitted by law, for all judgments, fines, settlements, legal fees and other expenses incurred in connection with pending or threatened legal proceedings because of the director’s or officer’s positions with us or another entity that the director or officer serves at our request, subject to various conditions, and to advance funds to our directors and officers to enable them to defend against such proceedings. To receive indemnification, the director or officer must have been successful in the legal proceeding or have acted in good faith and in what was reasonably believed to be a lawful manner in our best interest and, with respect to any criminal proceeding, had no reasonable cause to believe his or her conduct was unlawful.

Indemnification Agreements

Prior to the completion of this offering, we will enter into indemnification agreements with our directors. The indemnification agreements will provide the directors with contractual rights to the indemnification and expense advancement rights provided under our amended and restated by-laws, as well as contractual rights to additional indemnification as provided in the indemnification agreements.

The indemnification agreements will provide for the advancement or payment of all expenses to the indemnitee and for reimbursement to us if it is found that such indemnitee is not entitled to such indemnification under applicable law and our amended and restated certificate of incorporation and amended and restated by-laws.

Directors’ and Officers’ Liability Insurance

Prior to the completion of this offering, we will have obtained directors’ and officers’ liability insurance that insures against certain liabilities that our directors and officers and the directors and officers of our subsidiaries may, in such capacities, incur.

Underwriting Agreement

In the underwriting agreement we entered into in connection with the sale of the common stock being registered hereby, the underwriters have agreed to indemnify, under certain conditions, us, our directors, our officers and persons who control us within the meaning of the Securities Act, against certain liabilities, or to contribute to payments such parties may be required to make in respect of these liabilities.

Item 17.Undertakings.

Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the U.S. Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its

counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question of whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.

The undersigned registrant hereby undertakes that:

(1)For purposes of determining any liability under the Securities Act of 1933, the information omitted from the form of prospectus filed as part of this registration statement in reliance upon Rule 430A and contained in a form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be part of this registration statement as of the time it was declared effective.

(2)For the purpose of determining any liability under the Securities Act of 1933, each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

SIGNATURES

Pursuant to the requirements of the Securities Act of 1933, as amended, Leonardo DRS, Inc. has duly caused this registration statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of Arlington, State of Virginia on the day of , 2021.
