Table of Contents

Our operating subsidiaries are engaged primarily in the research, development, manufacture, sale and support of the products and systems described below. Their respective businesses are subject to a number of risks and uncertainties, including without limitation those discussed in Item 1A, “Risk Factors.” See also Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” and “Forward-Looking Information.”

We are continually seeking ways to reduce our overall operating costs, streamline business processes and enhance the branding of our products and services. During 2019, Doble sold its headquarters facility in Watertown, Massachusetts, and during 2020 it consolidated its headquarters operations into a single, more cost-efficient facility in Marlborough, Massachusetts. In 2021, Doble closed its facility in Toronto, Ontario and consolidated its Manta product line into its existing production capacity for Doble instruments.

We are also continually seeking opportunities to supplement our growth by making strategic acquisitions. In 2019 we acquired Globe Composite Solutions, LLC; in October 2020 we acquired Advanced Technology Machining, Inc. (ATM) and its sister company TECC Grinding, Inc.; in July 2021 we acquired I.S.A Altanova Group S.r.l. and its affiliated companies (Altanova); and in August 2021 we acquired the assets of Phenix Technologies Inc. (Phenix). Information about these acquired businesses is provided in the following section, “Products,” and in Note 2 to the Consolidated Financial Statements.

In December 2019, we sold the businesses comprising our former Technical Packaging segment and used the proceeds from the sale to pay down debt and for other corporate purposes, including the termination of our defined benefit pension plan. The Technical Packaging segment was reported as Discontinued Operations in 2020 and is presented accordingly for all periods in this report. See Note 3 to the Consolidated Financial Statements.

Products

Our principal products are described below. See Note 12 to the Consolidated Financial Statements for financial information regarding business segments and 10% customers.

A&D

Beginning in the first quarter of 2020, we renamed our Filtration/Fluid Flow segment as Aerospace & Defense to better reflect the composition of the segment’s products, end markets and customer characteristics. The A&D segment’s individual legal and operating entities and historical financial results are unchanged from what was formerly presented as Filtration/Fluid Flow.

The A&D segment accounted for approximately 44%, 48% and 45% of our total revenue in 2021, 2020 and 2019, respectively.

Our companies within this segment primarily design and manufacture specialty filtration, fluid control and naval products, including hydraulic filter elements and fluid control devices used in aerospace and defense applications, unique filter mechanisms used in micro-propulsion devices for satellites, custom designed filters for manned aircraft and submarines, products and systems to reduce vibration and/or acoustic signatures and otherwise reduce or obscure a vessel’s signature, and other communications, sealing, surface control and hydrodynamic related applications to enhance U.S. Navy maritime survivability; precision-tolerance machined components for the aerospace and defense industry; and metal processing services.The segment has six facilities in the United States and one in Mexico.

USG

Our USG segment accounted for approximately 28%, 26% and 29% of our total revenue in 2021, 2020 and 2019, respectively.

Doble is an industry leader in the development, manufacture and delivery of diagnostic testing and data management solutions that enable electric power grid operators to assess the integrity of high-voltage power delivery equipment. It combines three core elements for customers – diagnostic test instruments and condition monitoring systems, expert consulting, and testing services. The acquisition of Phenix’s assets has enhanced Doble’s high-voltage, high current, high power test systems, components and solutions. NRG is a global market leader in the design and manufacture of decision support tools for the renewable energy industry, primarily wind and solar. Doble and NRG together have eight facilities in the United States and one in Canada.

Altanova, headquartered in Taino, Italy, provides products and services in more than 100 countries. Its strong market share in Europe and Asia creates a significant international platform for our USG segment and fills important product gaps and geographies not previously served by our existing products and solutions. Doble’s offices outside North America have been consolidated with Altanova’s, and going forward we expect that Altanova will represent their combined businesses in markets outside the U.S. and Canada.

Test

Our Test segment accounted for approximately 28%, 26% and 26% of our total revenue in 2021, 2020 and 2019, respectively.

ETS-Lindgren is an industry leader in designing and manufacturing products which provide its customers with the ability to measure and contain magnetic, electromagnetic and acoustic energy. It supplies its customers with a broad range of isolated environments and turnkey systems, including RF test facilities, acoustic test enclosures, RF and magnetically shielded rooms, secure communication facilities, RF measurement systems and broadcast and recording studios. Many of these facilities include proprietary features such as shielded doors and windows. ETS-Lindgren also provides the design, program management, installation and integration services required to successfully complete these types of facilities.

ETS-Lindgren also supplies customers with a broad range of components including RF absorptive materials, RF filters, active compensation systems, antennas, antenna masts, turntables and electric and magnetic probes, RF test cells, proprietary measurement software and other test accessories required to perform a variety of tests. ETS-Lindgren offers a variety of services including calibration for antennas and field probes, chamber certification, field surveys, customer training and a variety of product tests. ETS-Lindgren’s test labs are accredited by the following organizations: American Association for Laboratory Accreditation, National Voluntary Laboratory Accreditation Program and CTIA-The Wireless Association Accredited Test Lab. ETS-Lindgren serves the acoustics, medical, health and safety, electronics, wireless communications, automotive and defense markets. ETS-Lindgren has four facilities in the United States and nine outside the United States.

Marketing and Sales

Our products generally are distributed to customers through a domestic and foreign network of distributors, sales representatives, direct sales teams and in-house sales personnel.

Our sales to international customers accounted for approximately 28%, 27% and 26% of our total revenue in 2021, 2020 and 2019, respectively. See Note 12 to the Consolidated Financial Statements for financial information by geographic area. See Item 1A, “Risk Factors,” for a discussion of risks related to our international operations.

Government Contracts

Some of our products are sold to the U.S. Government either directly under contracts with the Army, Navy and Air Force as well as other Government agencies or indirectly under subcontracts with their prime contractors. Direct and indirect sales to the U.S. Government, primarily related to the A&D segment, accounted for approximately 26%, 28% and 21% of our total revenue in 2021, 2020 and 2019, respectively.

Our Government contracts primarily include firm fixed-price contracts under which work is performed and paid for at a fixed amount without adjustment for the actual costs experienced in connection with the contracts. All Government prime contracts and virtually all of our Government subcontracts provide that they may be terminated at the convenience of the Government or the customer. Upon a termination for convenience, we are entitled to receive equitable compensation from the customer for the work we completed prior to termination.

Executive Order 14042, Ensuring Adequate COVID Safety Protocols for Federal Contractors, issued in September 2021, when implemented, will require government contractors and subcontractors to comply with certain COVID-19 safeguards in workplaces with covered individuals, including vaccination, masking and physical distancing protocols. We are taking steps to comply with the Executive Order at affected locations.

See Item 1A, “Risk Factors,” for a discussion of risks related to our Government business.

Intellectual Property

We own or have other rights in various forms of intellectual property (i.e., patents, trademarks, service marks, copyrights, mask works, trade secrets and other items). As a major supplier of engineered products to industrial and commercial markets, we emphasize developing intellectual property and protecting our rights therein. However, the legal protection afforded by intellectual property rights is often uncertain and can involve complex legal and factual issues. Some intellectual property rights, such as patents, have a limited term, and there can be no assurance that third parties will not infringe or design around our intellectual property. Policing the unauthorized use of intellectual property is difficult, and infringement and misappropriation are persistent problems for many companies, particularly in some international markets, and in some cases, we may elect not to pursue an unauthorized user due to the

Table of Contents

high costs and uncertainties associated with litigation. Further, there can be no assurance that courts will ultimately hold issued patents or other intellectual property valid and enforceable. See Item 1A, “Risk Factors.”

A number of products in the Aerospace & Defense segment are based on patented or otherwise proprietary technology that sets them apart from the competition, such as VACCO’s proprietary quieting technology and Westland’s signature reduction solutions. In addition, Globe has developed significant manufacturing and logistics capability useful for special hull treatments for submarines. Globe has also obtained patent protection in the U.S. and Europe for a novel shielding curtain to be used with electromagnetic radiation scanning systems.

In the USG segment, our policy is to seek patent and/or other forms of intellectual property protection on new and improved products, components of products, and methods of operation for our businesses, as such developments are made. Doble has obtained and is pursuing additional patent protection on improvements to its line of diagnostic equipment and NERC CIP compliance tools. Doble also holds an extensive library of apparatus performance information useful to entities that generate, distribute or consume electric energy, and it makes part of this library available to registered users via an Internet portal. NRG has intellectual property related to certain LIDAR technology and applications, and has obtained and is pursuing additional patent protection on its line of bat deterrent systems, which are designed to significantly reduce bat mortality at windfarms and in other applications where bat conservation is a concern.

In the Test segment, we have sought patent protection for significant inventions. Examples of such inventions include novel designs for window and door assemblies used in shielded enclosures and anechoic chambers, improved acoustic techniques for sound isolation and a variety of unique antennas. In addition, the Test segment holds a number of patents, and has patents pending, on products used to perform wireless device testing.

We consider our patents and other intellectual property to be of significant value to each of our segments.

Backlog

Total Company backlog of firm orders at September 30, 2021 was $592.0 million, representing an increase of $80.8 million (15.8%) from the backlog of $511.2 million at September 30, 2020. By segment, the backlog at September 30, 2021 and September 30, 2020, respectively, was $367.2 million and $344.7 million for A&D; $91.6 million and $50.7 million for USG; and $133.2 million and $115.9 million for Test. We estimate that as of September 30, 2021 domestic customers accounted for approximately 73% of our total firm orders and international customers accounted for approximately 27%. Of our total backlog at September 30, 2021, approximately 75% is expected to be completed in the fiscal year ending September 30, 2022.

Purchased Components and Raw Materials

Our products require a wide variety of components and materials. Although we have multiple sources of supply for most of our materials requirements, certain components and raw materials are supplied by sole source vendors, and our ability to perform certain contracts depends on their timely performance. In the past, these required raw materials and various purchased components generally have been available in sufficient quantities. However, we do have some risk of shortages of materials or components due to reliance on sole or limited sources of supply; and supplies of components and materials are periodically impacted by disruptions due to COVID-19 as well as complications due to current or future trade policies. Where feasible, we engineer and qualify substitute products to avoid short-term supply issues; however, we are subject to the same supply chain risks as other electronics manufacturers. An unanticipated delay in delivery by our suppliers could result in the inability to deliver our products on-time and to meet the expectations of our customers. Additionally, we have experienced, and could continue to experience, an increase in the costs of doing business, including increasing raw material prices and transportation costs, which have and could continue to have an adverse impact on our business, results of operations, financial condition and cash flows. See also Item 1A, “Risk Factors.”

Our A&D segment purchases supplies from a wide array of vendors. In most instances, multiple vendors of raw materials are screened during a qualification process to ensure that there will not be an interruption of supply should one of them underperform or discontinue operations. Nonetheless, in some situations, there is a risk of shortages due to reliance on a limited number of suppliers or because of price fluctuations due to the nature of the raw materials. For example, aerospace-grade titanium and gaseous helium, important raw materials for our A&D segment subsidiaries, may at times be in short supply.

Our USG segment manufactures electronic instrumentation through a network of regional contract manufacturers under long-term contracts. In general, USG purchases the same kinds of component parts as do other electronic products manufacturers, and these electronic components can be subject to supply chain constraints. USG purchases only a limited amount of raw materials.

Table of Contents

Our Test segment is a vertically integrated supplier of electro-magnetic (EM) shielding and RF absorbing products, producing most of its critical RF components itself. This segment purchases significant quantities of raw materials such as polyurethane foam, polystyrene beads, steel, aluminum, copper, nickel and wood. Accordingly, it is subject to price fluctuations in the worldwide raw materials markets. While ETS-Lindgren has long-term contracts with a number of its suppliers, performance of these contracts is vulnerable to the risks described below and in Item 1A.

Competition

Competition in our major markets is broadly based and global in scope. This competition can be particularly intense during periods of economic slowdown, and we have experienced this in some of our markets. Although we are a leading supplier in several of the markets we serve, we maintain a relatively small share of the business in many of our other markets. Individual competitors range in size from annual revenues of less than $1 million to billion-dollar enterprises. Because of the specialized nature of our products, our competitive position with respect to our products cannot be precisely stated. In our major served markets, competition is driven primarily by quality, technology, price and delivery performance. See also Item 1A, “Risk Factors.”

Primary competitors of our A&D segment include Pall Corporation, Moog, Inc., Safran (Sofrance), CLARCOR Inc., TransDigm (PneuDraulics), Marotta Controls, and Parker Hannifin.

Significant competitors of our USG segment include OMICRON electronics Corp., Megger Group Limited, Vaisala, and Qualitrol Company LLC (a subsidiary of Fortive Corporation).

Our Test segment is a global leader in EM shielding. Significant competitors in this market include Rohde & Schwarz GMBH, Microwave Vision SA (MVG), TDK RF Solutions Inc., Albatross GmbH, IMEDCO AG, and Universal Shielding Corp.

Research and Development

Research and development and our technological expertise are important factors in our business. Our research and development programs are designed to develop technology for new products or to extend or upgrade the capability of existing products, and to enhance their commercial potential. We perform research and development at our own expense, and also engage in research and development funded by our customers. See Note 1 to the Consolidated Financial Statements for financial information about our research and development expenditures.

Environmental Matters and Government Regulation

We are involved in various stages of investigation and cleanup relating to environmental matters. It is difficult to estimate the potential costs of these matters and the possible impact of these costs on the Company at this time due in part to: the uncertainty regarding the extent of pollution; the complexity and changing nature of Government laws and regulations and their interpretations; the varying costs and effectiveness of alternative cleanup technologies and methods; the uncertain level of insurance or other types of cost recovery; the uncertain level of our responsibility for any contamination; the possibility of joint and several liability with other contributors under applicable law; and the ability of other contributors to make required contributions toward cleanup costs. Based on information currently available, we do not believe that the aggregate costs involved in the resolution of environmental matters or compliance with Governmental regulations will have a material adverse effect on our financial condition or results of operations.

Human Capital Management

As of September 30, 2021, we employed 2,822 persons, including 2,700 full time employees of whom 15% were located in 14 foreign countries.

As a responsible member of the communities in which we operate, we are dedicated to preserving operational excellence and remaining an employer of choice. We provide and maintain a work environment that attracts, develops and retains top talent by offering our employees an engaging work experience that contributes to their career development. Through our charitable Foundation and wellness activities we provide opportunities for meaningful civic involvement that not only support our communities but also provide experiences for our employees to promote a collaborative and rewarding work environment. We strive to maintain a culture that enables all employees to be treated with dignity and respect while devoting their best efforts to performing their jobs to the best of their abilities. We operate in a supportive culture that incorporates strong ethical behavior and reinforces our human rights commitment through annual ethics training which incorporates instruction on human rights, anti-human trafficking, and anti-harassment, as well as other areas of importance such as supervisory training on diversity and inclusion.

Table of Contents

Our subsidiaries enjoy modest turnover at less than half the national average for our industry. Fewer than 4% of our workforce are contingent workers. We invest in creating a diverse, inclusive and safe work environment which will inspire our employees to give their best efforts every day. In fact, nearly half of our employee base comes from diverse backgrounds.

We generally conduct formal compensation benchmarking reviews every 1-2 years to ensure wages are competitive in local markets and support retention and recruiting efforts. Additionally, we invest time and resources in reviewing pay equity within our workforce. All full-time domestic and international employees are eligible for bonus or commission plans, most of which are designed to incentivize and reward performance based on results such as EPS, EBIT, cash flow, quality and backlog reduction, or other measures.

We recognize that our success is based on the talents and dedication of those we employ, and we are invested in their success. Significant investments are made in the areas of talent development, technical skills and compliance (ethics, safety, hazmat, ITAR, etc.). For succession planning purposes, we focus on identifying high-potential future leaders and working with them on individual development plans.

Our product development and manufacturing processes require a variety of manufacturing and testing tools and equipment. As a part of our commitment to the safety of our employees, customers, suppliers and third parties, we have established safety programs, policies, procedures and training requirements. Our local safety committees meet routinely throughout the year to ensure the safety of our employees, and that is reflected in our experience with lost time injuries, which is below industry incidence rates.

Throughout 2021, our attention continued to be focused on the effective handling of the COVID-19 pandemic and included maintaining the re-layout of many of our factory floors to ensure sufficient distancing in high density areas. We also installed shields, modified training programs to comply with distancing requirements, limited visitor entry, continued the use of virtual meetings, and adjusted shifts to aid in physical distancing. We also implemented the use of remote work arrangements and encouraged employees to receive, and provided time off for, vaccinations.

We are committed to the health and wellbeing of our employees and their families by encouraging participation in wellness programs. Generally, all our full-time employees, both domestic and international, are offered health and welfare benefits. We remain committed to our communities through financial support from our employees and the ESCO Foundation, and through personal participation of our employees with a variety of local organizations, such as, Family Outreach, the Boys & Girls Club, the United Way, and Special Olympics. We believe strong human capital is our competitive differentiator, and we focus not only on ensuring we have the right domestic and international talent in place to drive our strategic initiatives today, but well into the future.

COVID-19 Related Risks

The COVID-19 pandemic and its widespread effects on the United States and global economies may have a material adverse effect on our business which could continue for an unknown period of time.

The COVID-19 pandemic has significantly increased our economic, demand and operational uncertainty. The rapid worldwide spread of the COVID-19 virus, as well as the measures governments and private organizations have implemented in order to stem the spread of this pandemic, is resulting in significant worldwide disruptions and contractions in economic activity, including those resulting from “shelter in place” and similar orders, restrictions on non-essential business operations and travel, and increased unemployment. We have global operations, customers and suppliers, including in countries most impacted by COVID-19, and both the disease itself and the actions taken around the world to slow the spread of COVID-19 have impacted our customers and suppliers; and future developments could cause further disruptions to the Company due to the interconnected nature of our business relationships.

We have been and may continue to be subject to postponement or cancellation of certain contracts to which we are a party. We have also suffered a significant reduction in our commercial aircraft business due to slowdowns in OEM production and reduced flights, and this business is unlikely to return to pre-COVID levels for an unknown but possibly significant period of time. Current restrictions and conditions have and may continue to prevent or delay us in accessing customer facilities to deliver products and provide services, and disrupt or delay our supply chain. Even though our businesses have been classified as essential businesses and allowed to remain in operation in jurisdictions in which facility closures have been mandated, we can give no assurance that this will not change in the future or that our businesses will be classified as essential in each of the jurisdictions in which we operate. Further, although we have implemented prevention measures at our own facilities, including enhanced cleaning procedures, social distancing efforts and working from home where feasible, and substantially all of our facilities have so far remained in business, we have occasionally incurred short-term disruptions in some facility operations, and due to the nature of the COVID-19 pandemic there can be no assurance that we will not suffer facility closures or other adverse effects on our business operations in the future.

The facilities of our suppliers and customers have experienced, and may continue to experience, disruptions in manufacturing and supply arrangements due to the loss or disruption of critical manufacturing and supply elements, such as raw materials or other finished product components, transportation, workforce or other manufacturing and distribution capability. We may also experience failure of third parties on which we rely, including our suppliers, distributors and contractors, to meet their obligations to us, or significant restrictions in their ability to do so. In addition, our compliance with applicable safety requirements may cause us to lose critical employees who are unwilling or unable to comply with the requirements.

These facts and circumstances may have a material adverse effect on our business, results of operations, financial condition and cash flows. The extent to which the COVID-19 pandemic will impact our business, results of operations, financial condition and cash flows in the future, and the length of time these impacts may continue, will depend on future developments that are highly uncertain and cannot be predicted at this time, including new information that may emerge concerning the severity of COVID-19, the longevity of COVID-19 and the actions to contain its impact.

Risks Related to our Governmental and Aerospace Business

Our sales of products to the Government depend upon continued Government funding.

Sales to the U.S. Government and its prime contractors and subcontractors represent a significant portion of our business. Over the past three fiscal years, from 21% to 28% of our revenues have been generated from sales to the U.S. Government or its contractors, primarily within our A&D segment. These sales are dependent on government funding of the underlying programs, which is generally subject to annual Congressional appropriations. There could be reductions or terminations of, or delays in, the government funding on programs which apply to us or our customers. These funding effects could adversely affect our sales and profit, and could bring about a restructuring of our operations, which could result in an adverse effect on our financial condition or results of operations. A significant portion of VACCO’s, Westland’s and Globe’s sales involve major U.S. Government programs such as NASA’s Space Launch System (SLS) and U.S. Navy submarines. A reduction or delay in Government spending on these programs could have a significant adverse impact on our financial results which could extend for more than a single year.

Our Government business increases the risk that we may not realize the full amount of our backlog.

As of September 30, 2021, our twelve-month backlog was approximately $441 million, which represents confirmed orders we believe will be recognized as revenue within the next twelve months. There can be no assurance that our customers will purchase all the orders represented in our backlog, particularly as to contracts which are subject to the U.S. Government’s and its subcontractors’ ability to modify or terminate major programs or contracts, and if and to the extent that this occurs, our future revenues could be materially reduced.

The end of customer product life cycles could negatively affect our A&D segment’s results.

Many of our A&D segment products are sold to be components in our customers’ end-products. If a customer discontinues a certain end-product line, our ability to continue to sell those components will be reduced or eliminated. The result could be a significant decrease in our sales. For example, a substantial portion of PTI’s revenue is generated from commercial aviation aftermarket sales. As certain aircraft are retired and replaced by newer aircraft, there could be a corresponding decrease in sales associated with our current products. Such a decrease could adversely affect our operating results.

Risks Related to our International Business

Negative worldwide economic conditions and related credit shortages could result in a decrease in our sales and an increase in our operating costs, which could adversely affect our business and operating results.

If there is a worsening of global and U.S. economic and financial market conditions and additional tightening of global credit markets, many of our customers may further delay or reduce their purchases of our products. Uncertainties in the global economy may cause the utility industry and commercial market customers to experience shortages in available credit, which could limit capital spending. To the extent this problem affects our customers, our sales and profits could be adversely affected. Likewise, if our suppliers face challenges in obtaining credit, they may have to increase their prices or become unable to continue to offer the products and services we use to manufacture our products, which could have an adverse effect on our business, results of operations and financial condition.

Increases in tariffs or other changes in trade policies could adversely affect our ability to compete.

In addition to the effects of increases in market prices, increases in domestic import tariffs could increase the prices to us of our foreign-sourced raw materials and product components and thereby require us to either increase our selling prices or accept reduced margins. In the case of ETS-Lindgren, for example, tariffs on imports of Chinese goods have raised the costs of components purchased by it either from its China facility or from other Chinese suppliers, and its margins in China have been impacted by the increased costs of its products made in the U.S. and sold through its Chinese business.

In addition, increases in foreign-country tariffs applicable to our exported products could increase the effective prices of our products to our customers in those countries unless we are able to offset the tariffs by reducing our selling prices. Any or all of these factors could decrease the demand for our products, reduce our profitability, and/or make our products less competitive than those of other manufacturers that are not subject to the same tariffs. For example, since 2019 increased tariffs imposed by China on U.S. origin goods have adversely affected sales of NRG’s products in China by increasing their prices to Chinese customers.

Table of Contents

In addition, trade restrictions against certain foreign-made products or entities may adversely affect our business and our ability to compete in certain markets. Our business may also be impacted by the ongoing trade tensions between the U.S. and China which are causing U.S. goods to be viewed in a less favorable light by Chinese customers.

Our international operations expose us to fluctuations in currency exchange rates that could adversely affect our results of operations and cash flows.

We have significant manufacturing and sales activities in foreign countries, and our domestic operations have sales to foreign customers. Our financial results may be affected by fluctuations in foreign currencies and by the translation of the financial statements of our foreign subsidiaries from local currencies into U.S. dollars, and we may not be able to adequately or successfully hedge against these risks. In addition, a rise in the dollar against foreign currencies could make our products more expensive for foreign customers and cause them to reduce the volume of their purchases.

Economic, political and other risks of our international operations, including terrorist activities, could adversely affect our business.

In 2021, approximately 28% of our net sales were to customers outside the United States. Increases in international tariffs resulting from changes in domestic or foreign trade policies could increase the costs of the raw materials used in our products and/or the costs of our products. In addition, an economic downturn or an adverse change in the political situation in certain foreign countries in which we do business could cause a decline in revenues and adversely affect our financial condition. For example, our Test segment does significant business in Asia, and changes in the Asian political climate or political changes in specific Asian countries could negatively affect our business; several of our subsidiaries are based in Europe and could be negatively impacted by weakness in the European economy; and Doble’s future business in the Middle East could be adversely affected by continuing political unrest, wars and terrorism in the region.

Our international sales are also subject to other risks inherent in foreign commerce, including currency fluctuations and devaluations, differences in foreign laws, uncertainties as to enforcement of contract or intellectual property rights, and difficulties in negotiating and resolving disputes with our foreign customers.

Our governmental sales and our international and export operations are subject to special U.S. and foreign government laws and regulations which may impose significant compliance costs, create reputational and legal risk, and impair our ability to compete in international markets.

The international scope of our operations subjects us to a complex system of commercial and trade regulations around the world, and our foreign operations are governed by laws and business practices that often differ from those of the U.S. In addition, laws such as the U.S. Foreign Corrupt Practices Act and similar laws in other countries increase the need for us to manage the risks of improper conduct not only by our own employees but by distributors and contractors who may not be within our direct control. Many of our exports are of products which are subject to U.S. Government regulations and controls such as the U.S. International Traffic in Arms Regulations (ITAR), which impose certain restrictions on the U.S. export of defense articles and services, and these restrictions are subject to change from time to time, including changes in the countries into which our products may lawfully be sold.

If we were to fail to comply with these laws and regulations, we could be subject to significant fines, penalties and other sanctions including the inability to continue to export our products or to sell our products to the U.S. Government or to certain other customers. In addition, some of these regulations may be viewed as too restrictive by our international customers, who may elect to develop their own domestic products or procure products from other international suppliers which are not subject to comparable export restrictions; and the laws, regulations or policies of certain other countries may also favor their own domestic suppliers over foreign suppliers such as the Company.

Risks Related to our Manufacturing and Sales Operations and Technology

Disruptions of Our Information Technology Systems, or Information Security and/or Data Privacy Breaches, Could Adversely Affect Our Business.

We have many information technology systems that are important to the operation of our businesses, some of which are managed by third parties. These systems are used to obtain, process, transmit and store electronic information and to manage or support a variety of

10

Table of Contents

integral business processes and activities. Our primary and backup computer systems are vulnerable to damage, disruptions or shutdowns during the process of upgrading or replacing software, databases or components and from power outages, computer and telecommunication failures, security breaches, natural disasters and errors by employees. Any failure in the operation of our information technology systems could adversely affect our businesses or operating results. Although losses arising from some of these issues may be covered by information security insurance, we cannot guarantee that our coverage will be adequate for all costs or losses incurred.

Global information technology security threats and targeted computer crime are increasing in frequency and sophistication and pose a risk to the security of our systems and networks and the confidentiality, availability and integrity of our data and communications. We attempt to mitigate these risks through numerous measures, including employee training and testing, comprehensive monitoring of our networks and systems, and maintenance of backup and protective systems. Although we do not believe we have experienced a material information security breach in the last three years, and we have incurred no fines, settlement costs or other material expenses related to information security breaches, if we were to experience such a breach it could adversely affect our reputation and result in litigation, regulatory action, liability for fines, penalties and related expenses, and costs of implementing additional data protection procedures. In addition, even though we generally do not conduct business directly with retail or individual customers or consumers we must comply with increasingly complex and rigorous regulatory standards enacted to protect business and personal data in the U.S. and elsewhere. Compliance with data privacy laws and regulations increases operational complexity, and failure to comply with legal or regulatory standards could subject us to fines and penalties, as well as legal and reputational risks, including proceedings against us by governmental entities or others. Although we maintain insurance coverage for data privacy risks, we cannot guarantee that our coverage will be adequate for all costs or losses incurred.

A significant part of our manufacturing operations depends on a small number of third-party suppliers.

A significant part of our manufacturing operations relies on a small number of third-party manufacturers to supply component parts or products. For example, Doble has arrangements with six manufacturers which produce and supply a substantial portion of its end-products, and one of these suppliers produces approximately 35% of Doble’s products from a single location within the United States. As another example, PTI has a single supplier of critical electronic components for a significant aircraft production program, and if this supplier were to discontinue producing these components the need to secure another source could pose a risk to the production program. A significant disruption in the supply of those products or others provided by a small number of suppliers could negatively affect the timely delivery of products to customers as well as future sales, which could increase costs and reduce margins.

Certain of our other businesses are dependent upon sole source or a limited number of third-party manufacturers of parts and components. Many of these suppliers are small businesses. Since alternative supply sources are limited, there is an increased risk of adverse impacts on our production schedules and profits if our suppliers were to default in fulfilling their price, quality or delivery obligations. In addition, some of our customers or potential customers may prefer to purchase from a supplier which does not have such a limited number of sources of supply.

Increases in prices of raw material and components, and decreased availability of such items, could adversely affect our business.

The cost of raw materials and product components is a major element of the total cost of many of our products. For example, our Test segment’s critical components rely on purchases of raw materials from third parties. Increases in the prices of raw materials (such as steel, copper, nickel, zinc, wood and petrochemical products) could have an adverse impact on our business by, among other things, increasing costs and reducing margins. Aerospace-grade titanium and gaseous helium, important raw materials for our A&D segment, may at times be in short supply; in addition, although we try to tie our supplier pricing to long-term contracts this is not always possible, and we are experiencing price inflation on a number of products. Further, some of Doble’s items of equipment which are provided to its customers for their use are in the maturity of their life cycles, which creates the risk that replacement components may be unavailable or available only at increased costs. Doble has experienced COVID-related short term disruptions in the supply chain which have periodically resulted in extended lead times and cost increases, and the long term impacts of these disruptions are uncertain. See also “COVID-19 Related Risks” above.

In addition, our reliance on sole or limited sources of supply of raw materials and components in each of our segments could adversely affect our business, as described in the preceding Risk Factor. The potential physical impacts of climate change, such as increased frequency and severity of storms, floods and other climatic events, could disrupt our supply chain, and cause our suppliers to incur significant costs in preparing for or responding to these effects. These and other weather-created disruptions in supply, in addition to affecting costs, could impact our ability to procure an adequate supply of these raw materials and components, and delay or prevent deliveries of products to our customers. The entire electronics industry is currently disrupted due to limited sources of supply, and we

11

Table of Contents

are subject to the same supply chain risks as other manufacturers of products containing electronic components. See also “COVID-19 Related Risks” above.

Our inability to timely develop new products could reduce our future sales.

Much of our business is dependent on the continuous development of new products and technologies to meet the changing needs of our markets on a cost-effective basis. Many of these markets are highly technical from an engineering standpoint, and the relevant technologies are subject to rapid change. If we fail to timely enhance existing products or develop new products as needed to meet market or competitive demands, we could lose sales opportunities, which would adversely affect our business. In addition, in some existing contracts with customers, we have made commitments to develop and deliver new products. If we fail to meet these commitments, the default could result in the imposition on us of contractual penalties including termination. Our inability to enhance existing products in a timely manner could make our products less competitive, while our inability to successfully develop new products may limit our growth opportunities. Development of new products and product enhancements may also require us to make greater investments in research and development than we now do, and the increased costs associated with new product development and product enhancements could adversely affect our operating results. In addition, our costs of new product development may not be recoverable if demand for our products is not as great as we anticipate it to be.

Product defects or customer claims could result in costly fixes, litigation and damages.

Our business exposes us to potential product liability risks that are inherent in the design, manufacture and sale of our products and the products of third-party vendors which we use or resell, many of which are mission-critical to our customers. If there are claims related to defective products (under warranty or otherwise), particularly in a product recall situation, we could be faced with significant expenses in replacing or repairing the product. For example, the A&D segment obtains raw materials, machined parts and other product components from suppliers who provide certifications of quality which we rely on. Should these product components be defective and pass undetected into finished products, or should a finished product contain a defect, we could incur significant costs for repairs, re-work and/or removal and replacement of the defective product. In addition, if a dispute over product claims cannot be settled, arbitration or litigation may result, requiring us to incur attorneys’ fees and exposing us to the potential of damage awards against us.

A major portion of our Test segment’s business involves working in conjunction with general contractors to produce complex building components constructed on-site, such as electronic test chambers, secure communication rooms and MRI facilities. If there are performance problems caused by either us or a contractor, they could result in cost overruns and may lead to a dispute as to which party is responsible. The resolution of such disputes can involve arbitration or litigation, and can cause us to incur significant expense including attorneys’ fees. In addition, these disputes could result in a reduction in revenue, a loss on a particular project, or even a significant damages award against us.

Despite our efforts, we may be unable to adequately protect our intellectual property.

Much of our business success depends on our ability to protect and freely utilize our various intellectual properties, including both patents and trade secrets. Despite our efforts to protect our intellectual property, unauthorized parties or competitors may copy or otherwise obtain and use our products and technology, particularly in foreign countries such as China where the laws may not protect our proprietary rights as fully as in the United States. Our current and future actions to enforce our proprietary rights may ultimately not be successful; or in some cases we may not elect to pursue an unauthorized user due to the high costs and uncertainties associated with litigation. We may also face exposure to claims by others challenging our intellectual property rights. Any or all of these actions may divert our resources and cause us to incur substantial costs.

Environmental laws and regulations or environmental contamination could increase our expenses and adversely affect our profitability.

Our operations and properties are subject to U.S. and foreign environmental laws and regulations governing, among other things, the generation, storage, emission, discharge, transportation, treatment and disposal of hazardous materials and the clean-up of contaminated properties. In addition, governments around the world are increasingly focused on enacting laws and regulations regarding climate change and regulation of greenhouse gases. These regulations, and changes to them, could increase our cost of compliance, and our failure to comply could result in the imposition of significant fines, suspension of production, alteration of

12

Table of Contents

product processes, cessation of operations or other actions which could materially and adversely affect our business, financial condition and results of operations.

We are currently involved as a responsible party in several ongoing investigations and remediations of contaminated third-party owned properties. In addition, environmental contamination may be discovered in the future on properties which we formerly owned or operated and for which we could be legally responsible. Future costs associated with these situations, including ones which may be currently unknown to us, are difficult to quantify but could have a significant effect on our financial condition. See Item 1, “Business – Environmental Matters” for a discussion of these factors.

Risks Related to Our Business Strategy and Corporate Structure

Changes in testing standards could adversely impact our Test and USG segments’ sales.

A significant portion of the business of our USG and Test segments involves sales to technology customers who need to have a third party verify that their products meet specific international and domestic test standards. If regulatory agencies were to eliminate or reduce certain domestic or international test standards, or if demand for product testing from these customers were to decrease for some other reason, our sales could be adversely affected. For example, if a regulatory authority were to relax the test standards for certain electronic devices because they were determined not to interfere with the broadcast spectrum, or if new wireless communication technologies were developed that required less testing or different types of testing, our sales of certain testing products could be significantly reduced.

We may not be able to identify suitable acquisition candidates or complete acquisitions successfully, which may inhibit our rate of growth.

As part of our growth strategy, we plan to continue to pursue acquisitions of other companies, assets and product lines that either complement or expand our existing business. However, we may be unable to implement this strategy if we are unable to identify suitable acquisition candidates or consummate future acquisitions at acceptable prices and terms. We expect to face competition for acquisition candidates which may limit the number of acquisition opportunities available to us and may result in higher acquisition prices. As a result, we may be limited in the number of acquisitions which we are able to complete and we may face difficulties in achieving the profitability or cash flows needed to justify our investment in them.

Our acquisitions of other companies carry risk.

Acquisitions of other companies involve numerous risks, including difficulties in the integration of the operations, technologies and products of the acquired companies, the potential exposure to unanticipated and undisclosed liabilities, the potential that expected benefits or synergies are not realized and that operating costs increase, the potential loss of key personnel, suppliers or customers of acquired businesses and the diversion of Management’s time and attention from other business concerns. Although we attempt to identify and evaluate the risks inherent in any acquisition, we may not properly ascertain or mitigate all such risks, and our failure to do so could have a material adverse effect on our business.

We may incur significant costs, experience short-term inefficiencies, or be unable to realize expected long-term savings from facility consolidations and other business reorganizations.

We periodically assess the cost and operational structure of our facilities in order to manufacture and sell our products in the most efficient manner, and based on these assessments, we may from time to time reorganize, relocate or consolidate certain of our facilities. These actions may require us to incur significant costs and may result in short term business inefficiencies as we consolidate and close facilities and transition our employees; and in addition, we may not achieve the expected long-term benefits. Any or all of these factors could result in an adverse impact on our operating results, cash flows and financial condition.

Our inability to hire or retain qualified key employees could affect our performance and revenues.

There is a risk of our losing key employees having engineering and technical expertise. For example, our USG segment relies heavily on engineers with significant experience and reputation in the utility industry to furnish expert consulting services and support to customers, and our other segments similarly rely on qualified and experienced employees to carry on their businesses. Despite our active recruitment efforts, there remains a shortage of these qualified engineers and other employees because of hiring competition

13

Table of Contents

from other companies in the industry and a generally tight labor market, possibly exacerbated by COVID-related retirements or career changes. Losing current employees or qualified candidates to other employers or for other reasons could reduce our ability to provide services and negatively affect our revenues.

Our decentralized organizational structure presents certain risks.

We are a relatively decentralized company in comparison with some of our peers. This decentralization necessarily places significant control and decision-making powers in the hands of local management, which present various risks, including the risk that we may be slower or less able to identify or react to problems affecting a key business than we would in a more centralized management environment. We may also be slower to detect or react to compliance related problems (such as an employee undertaking activities prohibited by applicable law or by our internal policies), and Company-wide business initiatives may be more challenging and costly to implement, and the risks of noncompliance or failures higher, than they would be under a more centralized management structure. Depending on the nature of the problem or initiative in question, such noncompliance or failure could have a material adverse effect on our business, financial condition or result of operations.

Provisions in our articles of incorporation, bylaws and Missouri law could make it more difficult for a third party to acquire us and could discourage acquisition bids or a change of control, and could adversely affect the market price of our common stock.

Our articles of incorporation and bylaws contain certain provisions which could discourage potential hostile takeover attempts, including: a limitation on the shareholders’ ability to call special meetings of shareholders; advance notice requirements to nominate candidates for election as directors or to propose matters for action at a meeting of shareholders; a classified board of directors, which means that approximately one-third of our directors are elected each year; and the authority of our board of directors to issue, without shareholder approval, preferred stock with such terms as the board may determine. In addition, the laws of Missouri, in which we are incorporated, require a two-thirds vote of outstanding shares to approve mergers or certain other major corporate transactions, rather than a simple majority as in some other states such as Delaware. These provisions could impede a merger or other change of control not approved by our board of directors, which could discourage takeover attempts and in some circumstances reduce the market price of our common stock.

The Company is a component of both the Russell 2000 index and the S&P SmallCap 600 Industrials index.

We determined to use the S&P SmallCap 600 Industrials index for comparison beginning in 2021 rather than using a peer group of individual companies as we had done in prior years, because of the difficulty of finding comparable companies to select for the peer group and the frequent changes in the selected peer group from year to year necessitated by acquisitions, mergers or other transactions.

Because of this change, we also show the returns for the six remaining public companies in the customized peer group we used in 2020: CIRCOR International, Inc., Donaldson Company, Inc., Moog Inc., Ameresco, Inc., Thermon Group Holdings, Inc. and FARO Technologies, Inc. In calculating the composite return of the modified 2020 peer group, we weighted the return of each of the companies by (a) its market capitalization in relation to the other companies in its corresponding Company industry segment, and (b) the percentage of the Company’s total revenue from continuing operations represented by its corresponding Company industry segment.

The measurement period begins on September 30, 2016 and measures at each September 30 thereafter. These figures assume that all dividends, if any, paid over the measurement period were reinvested, and that the starting values of each index and the investments in our common stock and the modified 2020 peer group were $100 at the close of trading on September 30, 2016.

The following discussion should be read in conjunction with the Consolidated Financial Statements and Notes thereto and refers to our results from continuing operations except where noted.

Selected financial information for each of our business segments is provided in the discussion below and in Note 12 to the Company’s Consolidated Financial Statements.

This section includes comparisons of certain 2021 financial information to the same information for 2020. Year-to-year comparisons of the 2020 financial information to the same information for 2019 are contained in Item 7 of our Form 10-K for 2020 filed with the Securities and Exchange Commission on November 30, 2020 and available through the SEC’s website at https://www.sec.gov/edgar/searchedgar/companysearch.html.

Introduction

We classify our business operations into three segments for financial reporting purposes, although for reporting certain financial information we treat Corporate activities as a separate segment. Our three operating segments during 2021 were Aerospace & Defense (A&D), Utility Solutions Group (USG), and RF Shielding and Test (Test). Our operating segments are comprised of the following primary operating subsidiaries:

A&D. PTI, VACCO and Crissair primarily design and manufacture specialty filtration products, including hydraulic filter elements and fluid control devices used in commercial aerospace applications, unique filter mechanisms used in micro-propulsion devices for satellites and custom designed filters for manned aircraft and submarines. Westland and Globe design, develop and manufacture elastomeric-based signature reduction solutions for U.S. naval vessels. Mayday designs and manufactures mission-critical bushings, pins, sleeves and precision-tolerance machined components for landing gear, rotor heads, engine mounts, flight controls, and actuation systems for the aerospace and defense industries.

USG. Doble develops, manufactures and delivers diagnostic testing solutions that enable electric power grid operators to assess the integrity of high-voltage power delivery equipment. NRG designs and manufactures decision support tools for the renewable energy industry, primarily wind and solar.

Test. ETS-Lindgren is an industry leader in providing its customers with the ability to identify, measure and contain magnetic, electromagnetic and acoustic energy.

We continue to operate with meaningful growth prospects in our primary served markets and with considerable financial flexibility. We continue to focus on new products that incorporate proprietary design and process technologies. Our Management is committed to delivering shareholder value through organic growth, ongoing performance improvement initiatives, and acquisitions.

In December 2019, we sold the businesses comprising our former Technical Packaging segment. We received net proceeds from the sale of approximately $184 million and recorded $76.5 million of after-tax net earnings on the sale in 2020. The Technical Packaging segment is reflected as discontinued operations in the Consolidated Financial Statements and related notes for all periods presented, in accordance with accounting principles generally accepted in the United States of America (GAAP). See Note 3 to the Consolidated Financial Statements for further discussion.

COVID-19 Trends and Uncertainties

The COVID-19 global pandemic has continued to create significant and unprecedented challenges, and during these highly uncertain times, our top priority remains the health and safety of our employees, customers and suppliers, thereby securing the financial well-being of the Company and supporting business continuity. Given our diverse portfolio of strong, durable businesses serving non-discretionary end-markets, the strength and resilience of our business model positions us to continue to support our long-term outlook.

A portion of our workforce has worked from home at times due to COVID-19, however we have not had to redesign or design new internal controls over financial reporting at this time. Depending on the duration of COVID-19, it may become necessary for us to redesign or design new internal controls over financial reporting in a future period. We do not believe such an event will have a material impact on our business.

The economic uncertainty, changes in the propensity for the general public to travel by air, and reductions in demand for commercial aircraft as a result of the COVID-19 pandemic have adversely impacted net sales and operating results in certain of our A&D reporting units. We continue to monitor the impacts of COVID-19 for events or changes in circumstances that indicate the carrying amount of our assets may be impaired.

Throughout 2021, our Navy, defense aerospace, space and Test segment end-markets have remained solid and now we are beginning to see recovery in our core markets most affected by the pandemic. We are encouraged by the growing strength of our entered orders across the commercial aerospace, electric utility and renewable energy end-markets. While there is still uncertainty as to the timing and pace of recovery in the commercial aerospace and electric utility markets, we believe we now have a clearer picture of the near term. Increased U.S. domestic passenger boardings and recent orders for new planes by major airlines are encouraging signs for 2022.

The effects of the COVID-19 pandemic have adversely impacted our net sales and operating results in certain of our A&D reporting units that have a higher concentration of business serving the commercial aerospace industry. For the year ended September 30, 2021, we reviewed our indefinite lived intangible assets, long-lived assets and goodwill for impairment and determined that there was no impairment. The valuation methodology we use involves estimates of discounted cash flows, which are subject to change, and if they change negatively it could result in the need to write down those assets to fair value. We will continue to monitor the impacts of COVID-19 on the fair value of assets. The defense portion of A&D, both military aerospace and navy products, is expected to remain at approximately historical business levels given its backlog coupled with the timing of expected platform deliveries.

Results of Continuing Operations

Net Sales

​

​

Net sales decreased $15.1 million, or 2.1%, to $715.4 million in 2021 from $730.5 million in 2020. The decrease in net sales in 2021 as compared to 2020 was mainly due to a $37.1 million decrease in the A&D segment, partially offset by an $11.2 million increase in the USG segment, including $4.4 million of sales from the acquisitions of Altanova and the assets of Phenix, and a $10.8 million increase in the Test segment.

A&D.

The $37.1 million, or 10.5%, decrease in net sales in 2021 as compared to 2020 was mainly due to a $16.7 million decrease in net sales at Mayday, an $11.0 million decrease in net sales at Crissair, a $9.8 million decrease in net sales at PTI all primarily driven by the impact of the COVID-19 pandemic, and a $3.7 million decrease in net sales at Westland driven by new product development challenges, partially offset by a $3.7 million increase in net sales at Globe and a $0.4 million increase in net sales at VACCO driven by an increase in navy defense shipments.

Table of Contents

USG.

The $11.2 million, or 5.8%, increase in net sales in 2021 as compared to 2020 was mainly due to a $7.7 million increase in net sales at NRG driven by renewable energy products and $4.4 million of sales from the acquisitions of Altanova and the assets of Phenix that closed during the fourth quarter of 2021.

Test.

The $10.8 million, or 5.8%, increase in net sales in 2021 as compared to 2020 was mainly due to a $4.1 million increase in net sales from the Company’s Asian operations, $3.7 million increase in net sales from the Company’s U.S. operations and a $3.0 million increase in net sales from the Company’s European operations, primarily driven by the timing of test and measurement chamber projects.

Orders and Backlog

New orders received were $796.3 million in both 2021 and 2020. Order backlog was $592.0 million at September 30, 2021, compared to order backlog of $511.2 million at September 30, 2020. Orders are entered into backlog as firm purchase order commitments are received.

By operating segment, 2021 orders were $337.4 million related to A&D products, $243.9 million related to USG products (including $29 million of acquired backlog), and $215.0 million related to Test products; and 2020 orders were $420.4 million related to A&D products, $200.7 million related to USG products, and $175.3 million related to Test products.

Selling, General and Administrative Expenses

Selling, general and administrative (SG&A) expenses were $167.5 million, or 23.4% of net sales, in 2021, and $159.5 million, or 21.8% of net sales, in 2020.

The increase in SG&A expenses in 2021 as compared to 2020 was mainly due to an increase at Doble due to the return of discretionary spending to more normal levels, the inclusion of SG&A from the Phenix and Altanova acquisitions, compensation expenses due to the transition of key executives, and an increase in acquisition related costs at Corporate.

Amortization of Intangible Assets

Amortization of intangible assets was $20.8 million in 2021 and $21.8 million in 2020, including $14.3 million and $13.0 million of amortization of acquired intangible assets in 2021 and 2020, respectively, related to our acquisitions. The amortization of acquired intangible assets related to acquisitions is included in the Corporate segment’s results. The remaining amortization expenses relate to other identifiable intangible assets (primarily software, patents and licenses), which are included in the respective segment’s operating results. The decrease in amortization expense in 2021 as compared to 2020 was mainly due to a decrease in amortization of capitalized software.

Other Expenses or Income, Net

Other income, net, was $0.9 million in 2021, compared to other expenses, net, of $7.1 million in 2020. The principal components of other, net, in 2021 included a gain of approximately $2 million for the final settlement on the sale of the Doble Watertown, MA property, partially offset by facility consolidation charges within the USG segment (Doble Manta, Morgan Schaffer and Altanova facilities). The principal components of other expenses, net, in 2020 included approximately $8 million of pretax charges consisting primarily of facility consolidation charges for the Doble Manta facility, including employee severance and compensation benefits, and asset impairment charges. There were no other individually significant items included in other expenses, net, in 2021 or 2020.

Non-GAAP Financial Measures

The information reported herein includes the financial measures Diluted EPS – Continuing Operations As Adjusted, which we define as Diluted EPS – Continuing Operations excluding the per-share net impact of one-time compensation and acquisition related costs, facility consolidation charges within the USG segment, and purchase accounting charges related to the Company’s recent acquisitions

Table of Contents

in 2021, partially offset by a gain on the final installment of the Double Watertown, MA prrperty sale; and pension plan termination charge and restructuring charges related to our facility consolidation restructuring plans in 2020; EBIT, which we define as earnings before interest and taxes; and EBIT margin, which we define as EBIT expressed as a percentage of net sales. Diluted EPS – Continuing Operations As Adjusted, EBIT on a consolidated basis, and EBIT margin on a consolidated basis are not recognized in accordance with U.S. generally accepted accounting principles (GAAP). However, we believe that EBIT and EBIT margin provide investors and Management with valuable information for assessing our operating results. Management evaluates the performance of our operating segments based on EBIT and believes that EBIT is useful to investors to demonstrate the operational profitability of our business segments by excluding interest and taxes, which are generally accounted for across the entire company on a consolidated basis. EBIT is also one of the measures Management uses to determine resource allocations and incentive compensation. We believe that the presentation of EBIT, EBIT margin and Diluted EPS – Continuing Operations As Adjusted provides important supplemental information to investors by facilitating comparisons with other companies, many of which use similar non-GAAP financial measures to supplement their GAAP results. The use of non-GAAP financial measures is not intended to replace any measures of performance determined in accordance with GAAP.

EBIT

​

The reconciliation of EBIT to a GAAP financial measure is as follows:

​

​

EBIT by business segment is as follows:

​

​

A&D

The $13.4 million decrease in EBIT in 2021 as compared to 2020 was primarily due to charges at Westland driven by new product development challenges, increased production costs, and product quality issues; lower sales volumes at Mayday, Crissair and PTI; partially offset by an increase in EBIT at VACCO and Globe due to the higher sales volumes mentioned above. In addition, EBIT in 2021 was negatively impacted by a $0.3 million inventory step-up charge related to the acquisition of ATM.

USG

The $16.5 million increase in EBIT in 2021 as compared to 2020 was mainly due to higher sales volumes with a favorable product mix, approximately $2 million final settlement received on the sale of the Doble Watertown property, partially offset by $2.4 million of facility consolidation charges at its Doble Manta, Morgan Schaffer and Altanova facilities, and purchase accounting charges of approximately $1.0 million related to the Phenix and Altanova acquisitions mainly consisting of inventory step-up charges. In addition, NRG’s EBIT increased $3.1 million in 2021 due to higher sales volumes as compared to the prior year.

22

Table of Contents

Test

The $0.4 million increase in EBIT in 2021 as compared to 2020 was primarily due to product mix and increase in sales volumes as mentioned above partially offset by higher material prices.

Corporate

Corporate operating charges included in 2021 consolidated EBIT decreased to $42.1 million as compared to $78.4 million in 2020 mainly due to a $40.6 million pension plan termination charge in 2020 as a result of the decision to terminate and annuitize the Company’s defined benefit pension plan. Corporate’s operating charges were negatively impacted in 2021 due to higher compensation expenses due to the transition of key executives and an increase in acquisition related costs.

The “Reconciliation to Consolidated Totals (Corporate)” in Note 12 to the Consolidated Financial Statements represents Corporate office operating charges.

Interest Expense, Net

Interest expense, net was $2.2 million and $6.7 million in 2021 and 2020, respectively. The decrease in interest expense in 2021 was mainly due to lower average outstanding borrowings and lower average interest rates. Average outstanding borrowings were $71 million in 2021 compared to $176 million in 2020. The weighted average interest rates were 1.20% in 2021 compared to 3.20% in 2020.

Income Tax Expense

The effective tax rates from continuing operations for 2021, 2020 and 2019 were 21.3%, 37.1% and 20.8%, respectively. The 2020 effective tax rate was unfavorably impacted by a pension plan termination charge of $40.6 million which is not deductible for tax purposes, increasing the effective tax rate by 23.4%. The 2020 effective tax rate was favorably impacted by the following: (1) an increase in the available 2019 foreign tax credit which was attributable to new information and tax planning strategies reducing the 2020 effective tax rate by 1.9%; (2) the release of a valuation allowance of $2.8 million for foreign net operating losses decreasing the effective tax rate by 7.8%; and (3) favorable 2019 state tax return to provision true-ups decreasing the effective tax rate by 1.7%.

The 2017 Tax Cut and Jobs Act (TCJA) made comprehensive changes to U.S. federal income tax laws by moving from a global to a modified territorial tax regime. As a result, cash repatriated to the U.S. is generally no longer subject to U.S. federal income tax. No provision is made for foreign withholding any applicable U.S. income taxes on the undistributed earnings of non-U.S. subsidiaries where these earnings are considered indefinitely invested or otherwise retained for continuing international operations. Determination of the amount of taxes that might be paid on these undistributed earnings if eventually remitted is not practicable.

Acquisitions and Divestiture

Information regarding our acquisitions and divestiture during 2021, 2020 and 2019 is set forth in Notes 2 and 3 to the Consolidated Financial Statements, which Notes are incorporated by reference herein.

All of our acquisitions have been accounted for using the purchase method of accounting, and accordingly, the respective purchase prices were allocated to the assets (including intangible assets) acquired and liabilities assumed based on estimated fair values at the date of acquisition. The financial results from these acquisitions have been included in our financial statements from the date of acquisition.

Capital Resources and Liquidity

Our overall financial position and liquidity are strong. Working capital from continuing operations (current assets less current liabilities) increased to $188.4 million at September 30, 2021 from $187.8 million at September 30, 2020. Inventories increased by $11.9 million during 2021 mainly due to a $14.7 million increase within the USG segment driven by the acquisitions of Altanova and the assets of Phenix. Accounts payable increased by $6.1 million during 2021 mainly due to the USG segment driven by the Altanova and Phenix acquisitions.

23

Table of Contents

Net cash provided by operating activities from continuing operations was $123.1 million in 2021 and $108.5 million in 2020.

Net cash used in investing activities from continuing operations was $202.4 million in 2021 and $41.1 million in 2020. The increase in net cash used in investing activities in 2021 as compared to 2020 was mainly due to the Altanova and Phenix acquisitions totaling approximately $162 million. Capital expenditures from continuing operations were $26.7 million in 2021 and $32.1 million in 2020. The decrease in 2021as compared to 2020 was mainly due to the building improvement additions in 2020 at the new Doble headquarters facility. In addition, the Company incurred expenditures for capitalized software of $8.8 million in 2021 and $9.0 million in 2020.

There were no commitments outstanding that were considered material for capital expenditures at September 30, 2021, except for a commitment to purchase the NRG building for approximately $10 million which closed in the first quarter of fiscal 2022.

Net cash provided by financing activities from continuing operations was $81.5 million in 2021 compared to net cash used by financing activities from continuing operations of $(234.1) million in 2020, primarily due to the increase in borrowings in 2021 as a result of the Company’s recent acquisitions.

Bank Credit Facility

A description of our credit facility (the “Credit Facility”) is set forth in Note 8 to the Consolidated Financial Statements, which Note is incorporated by reference herein.

Cash flow from operations and borrowings under the Credit Facility is expected to provide adequate resources to meet our capital requirements and operational needs both for the next 12 months and for the foreseeable future.

Dividends

Since 2010, we have paid a regular quarterly cash dividend at an annual rate of $0.32 per share. We paid dividends totaling $8.3 million in both 2021 and 2020.

Off-Balance-Sheet Arrangements

We had no off-balance-sheet arrangements outstanding at September 30, 2021.

Share Repurchases

Information about our common stock repurchases is provided in Note 9 to the Consolidated Financial Statements.

Subsequent Event

On November 4, 2021, the Company acquired Networks Electronic Company, LLC. (NEco) which provides miniature electro-explosive devices utilized in mission-critical defense and aerospace applications. NEco is based in Chatsworth, CA and will become part of the A&D segment. Their annual sales are expected to be approximately $7 million in 2022.

Critical Accounting Policies

The preparation of financial statements in conformity with U.S. generally accepted accounting principles (GAAP) requires Management to make estimates and assumptions in certain circumstances that affect amounts reported in the Consolidated Financial Statements. In preparing these financial statements, Management has made its best estimates and judgments of certain amounts included in the Consolidated Financial Statements, giving due consideration to materiality. We do not believe there is a great likelihood that materially different amounts would be reported under different conditions or using different assumptions related to the accounting policies described below. However, application of these accounting policies involves the exercise of judgment and use of assumptions as to future uncertainties and, as a result, actual results could differ from these estimates. Our senior Management discusses the critical accounting policies described below with the Audit and Finance Committee of our Board of Directors on a periodic basis.

24

Table of Contents

The following discussion of critical accounting policies is intended to bring to the attention of readers those accounting policies which Management believes are critical to the Consolidated Financial Statements and other financial disclosure. It is not intended to be a comprehensive list of all significant accounting policies that are more fully described in Note 1 to the Consolidated Financial Statements.

Revenue Recognition

We account for revenue in accordance with ASC Topic 606, Revenue from Contracts with Customers. The unit of account in ASC Topic 606 is a performance obligation. The transaction price for our contracts represents our best estimate of the consideration we will receive and includes assumptions regarding variable consideration, as applicable, which are based on historical, current and forecasted information. The transaction price is allocated to each distinct performance obligation within the contract and recognized as revenue when, or as, the performance obligation is satisfied. Certain of our long-term contracts contain incentive fees that can increase the transaction price. These variable amounts generally are awarded upon achievement of certain performance metrics, program milestones or cost targets and can be based upon customer discretion. We include estimated amounts in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur. The estimated amounts are based on an assessment of our anticipated performance and all other information that is reasonably available to us.

Approximately 57% of the A&D segment’s revenue (25% of consolidated revenue) is recognized over time as the products do not have an alternative use and either we have an enforceable right to payment for costs incurred plus a reasonable margin or the inventory is owned by the customer. Selecting the method to measure progress towards completion for our contracts requires judgment and is based on the nature of the products or services to be provided.

The A&D segment generally uses the cost-to-cost method to measure progress on our contracts, as the rate at which costs are incurred to fulfill a contract best depicts the transfer of control to the customer. Under this method, we measure the extent of progress towards completion based on the ratio of costs incurred to date to the estimated costs at completion of the performance obligation, and we record revenue proportionally as costs are incurred based on an estimated profit margin.

The Test segment generally uses the milestone output method to measure progress on our contracts because it best depicts the transfer of control to the customer that occurs as we incur costs on our contracts. Under this method, we estimate profit as the difference between total revenue and total estimated costs at completion of a contract and recognize these revenues and costs based on milestones achieved.

Total contract cost estimates are based on current contract specifications and expected engineering requirements and require us to make estimates on expected profit. The estimates on profit are based on judgments we make to project the outcome of future events, and can often span more than one year and include labor productivity and availability, the complexity of the work to be performed, change orders issued by our customers, and other specialized engineering and production related activities. Our cost estimation process is based on historical results of contracts and historical actuals to original estimates, and the application of professional knowledge and experience of engineers and program managers along with finance professionals to these historical results. We review and update our estimates of costs quarterly or more frequently when circumstances significantly change, which can affect the profitability of our contracts.

For contracts where revenue is recognized over time, we recognize changes in estimated contract revenues, costs and profits using the cumulative catch-up method of accounting. This method recognizes the cumulative effect of changes on current and prior periods with the impact of the change from inception-to-date recorded in the current period. We have net revenue recognized in the current year from performance obligations satisfied in the prior year due to changes in our estimated costs to complete the related performance obligations. We recognize anticipated losses on contracts in full in the period in which the losses become known.

The impact of adjustments in contract estimates on our operating earnings can be reflected in either revenue or operating costs and expenses. The aggregate impact of adjustments in contract estimates increased our earnings before income tax and diluted earnings per share by $1.7 million and $0.05 per share, respectively, in 2021.

Income Taxes

We operate in numerous taxing jurisdictions and are subject to examination by various U.S. Federal, state and foreign jurisdictions for various tax periods. Our income tax positions are based on research and interpretations of the income tax laws and rulings in each of

25

Table of Contents

the jurisdictions in which we do business. Due to the subjectivity of interpretations of laws and rulings in each jurisdiction, the differences and interplay in tax laws between those jurisdictions, as well as the inherent uncertainty in estimating the final resolution of complex tax audit matters, Management’s estimates of income tax liabilities may differ from actual payments or assessments.

We account for income taxes under the asset and liability method. We recognize deferred tax assets and liabilities for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. We measure deferred tax assets and liabilities using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. We may reduce deferred tax assets by a valuation allowance if it is more likely than not that some portion of the deferred tax assets will not be realized. We recognize the effect on deferred tax assets and liabilities of a change in tax rates in income in the period that includes the enactment date. We regularly review our deferred tax assets for recoverability and establish a valuation allowance when Management believes it is more likely than not such assets will not be recovered, taking into consideration historical operating results, expectations of future earnings, tax planning strategies, and the expected timing of the reversals of existing temporary differences.

Goodwill and Other Long-Lived Assets

Our Management annually reviews goodwill and other long-lived assets for impairment or whenever events or changes in circumstances indicate the carrying amount may not be recoverable. If we determine that the carrying value of the goodwill and other long-lived assets may not be recoverable, we record a permanent impairment charge for the amount by which the carrying value of the goodwill and other long-lived assets exceeds its fair value. We measure fair value based on a discounted cash flow method using a discount rate determined by Management to be commensurate with the risk inherent in each of our reporting units’ or asset groups’ current business models. Our estimates of cash flows and discount rate are subject to change due to the economic environment, including such factors as interest rates, expected market returns and volatility of markets served. We believe that Management’s estimates of future cash flows and fair value are reasonable; however, changes in estimates could result in impairment charges. At September 30, 2021 we have determined that no goodwill or other long-lived assets were impaired.

We amortize intangible assets with estimable useful lives over their respective estimated useful lives to their estimated residual values, and review them for impairment whenever events or changes in business circumstances indicate the carrying value of the assets may not be recoverable.

Other Matters

Quantitative and Qualitative Disclosures about Market Risk

Market risks relating to our operations result primarily from changes in interest rates and changes in foreign currency exchange rates. We are exposed to market risk related to changes in interest rates, and we selectively use derivative financial instruments, including forward contracts and swaps, to manage these risks. Our Canadian subsidiary Morgan Schaffer has entered into foreign exchange contracts to manage foreign currency risk, because a portion of their revenue is denominated in U.S. dollars. We report all derivative instruments on our balance sheet at fair value. For derivative instruments designated as cash flow hedges, we defer the gain or loss on the derivative in accumulated other comprehensive income until recognized in earnings with the underlying hedged item. See further discussion regarding our market risks in “Market Risk Analysis,” above.

Item 9A. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Our Chief Executive Officer and Chief Financial Officer (“Certifying Officers”) carried out an evaluation of the effectiveness of the design and operation of the Company’s disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the Exchange Act) as of September 30, 2021. Our Certifying Officers concluded that, as a result of the material weaknesses in internal control over financial reporting as described below, our disclosure controls and procedures were not effective as of September 30, 2021. Disclosure controls and procedures are designed to ensure that information required to be disclosed by the Company in reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms.

In light of the material weaknesses at a reporting unit within the Company’s Aerospace & Defense (A&D) segment, described below, management performed additional analyses and other procedures to ensure that our Consolidated Financial Statements were prepared in accordance with U.S. generally accepted accounting principles (GAAP). Accordingly, management believes that the Consolidated Financial Statements included in this Annual Report on Form 10-K fairly present, in all material respects, our financial position, results of operations, and cash flows as of and for the periods presented in accordance with GAAP.

Management’s Report on Internal Control Over Financial Reporting

Management is responsible for establishing and maintaining adequate internal control over financial reporting, as defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act. The Company’s management, with participation of the Certifying Officers, under the oversight of our Board of Directors, evaluated the effectiveness of the Company’s internal control over financial reporting as of September 30, 2021 using the framework in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based upon that evaluation, management concluded that the Company’s internal control over financial reporting was not effective as of September 30, 2021, due to the material weaknesses in internal control over financial reporting, described below.

Based on this assessment, the Company’s management concluded that an effective risk assessment process responsive to changes in the operating environment and business at a reporting unit in the Company’s Aerospace & Defense (A&D) segment did not occur, resulting in the ineffective design and implementation of certain controls to reduce the risks of material misstatements at that reporting unit. Specifically, the design of certain controls over revenue recognition, and the accumulation of inventory costs and the determination of inventory carrying values were ineffective. The control deficiencies resulted in immaterial misstatements of net sales and cost of sales. The control deficiencies described above created a reasonable possibility that a material misstatement to the consolidated financial statements would not be prevented or detected on a timely basis. Therefore, we concluded that the deficiencies represent material weaknesses in the Company’s internal control over financial reporting and that our internal control over financial reporting was not effective as of September 30, 2021.

The Company acquired Altanova and the assets of Phenix (together, the “Acquired Businesses”) during the year ended September 30, 2021, and management excluded from its assessment of the effectiveness of the Company’s internal control over financial reporting as of September 30, 2021, the Acquired Businesses’ internal control over financial reporting associated with total assets representing 12.2 percent of consolidated assets, and total sales representing 0.6 percent of consolidated net sales, included in the consolidated financial statements of the Company as of and for the year ended September 30, 2021.

The Company’s independent registered public accounting firm, KPMG LLP, who audited the consolidated financial statements included in this Annual Report on Form 10-K issued an adverse opinion on the effectiveness of the Company’s internal control over financial reporting. KPMG LLP’s report appears on page F-33 of this Annual Report on Form 10-K.

Remediation

The Company is in the process of remediating the material weaknesses and is taking the following actions:

27

Table of Contents

We believe these measures will remediate the control deficiencies and strengthen internal control over financial reporting. The operating effectiveness of the revised and new controls are currently being assessed and the material weaknesses will be considered remediated only after the applicable controls have operated effectively for a sufficient period of time.

Changes in Internal Control Over Financial Reporting

No changes in the Company’s internal control over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act) occurred during the fiscal quarter ended September 30, 2021, that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders and Board of Directors

ESCO Technologies Inc.:

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of ESCO Technologies Inc. and subsidiaries (the Company) as of September 30, 2021 and 2020, the related consolidated statements of operations, comprehensive income, shareholders’ equity, and cash flows for each of the years in the three-year period ended September 30, 2021 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 September 30, 2021 and 2020, and the results of its operations and its cash flows for each of the years in the three-year period ended September 30, 2021, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of September 30, 2021, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission, and our report dated November 29, 2021 expressed an adverse opinion on the effectiveness of the Company’s internal control over financial reporting.

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 PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the 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.

Critical Audit Matters

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

Revenue Recognition — Estimate of contract costs at completion

As discussed in Notes 1 and 15 to the consolidated financial statements, the Company’s Aerospace & Defense segment enters into certain long-term fixed price contracts with aerospace and defense customers to produce various products. These products do not have an alternative use and the Company has an enforceable right to payment for costs incurred plus a reasonable margin. Revenue for these contracts is recognized over time generally using a cost-to-cost model. Under such model, the Company measures the extent of progress towards completion of these contracts based on the ratio of contract costs incurred to date to the estimate of total contract costs at completion. The estimation of these costs requires judgment by the Company given the unique product specifications and requirements for contracts related to the design, development, and manufacture of complex products.

We identified the assessment of the estimate of total contract costs at completion for certain contracts in the Aerospace & Defense segment for which revenue is recognized over time using a cost-to-cost model as a critical audit matter. Complex auditor

judgment was required in evaluating expected engineering and production requirements of the contracts and the associated cost estimates for labor hours and materials, which represent assumptions with a high level of estimation uncertainty and that are also susceptible to potential management bias. Changes to these estimates may have a significant impact on the net sales and earnings recorded during the fiscal year.

The following are the primary procedures we performed to address this critical audit matter. We evaluated the design and tested the operating effectiveness of certain internal controls related to the Company’s revenue recognition process. This included controls over the accumulation and estimation of costs to complete for labor hours and materials for the contracts described above. For a selection of contracts, we compared the Company’s historical estimated costs and profit margin to the actual costs and profit margin for completed contracts to assess the Company’s ability to accurately estimate costs. We challenged the Company’s assumptions for labor hours and materials to be incurred for a selection of contracts by:

Sufficiency of audit evidence obtained over net sales

As discussed in Notes 1 and 15 to the consolidated financial statements, sales are recognized primarily from the sale of products across various industries and through multiple Company subsidiaries and locations around the world. The Company recorded $715.4 million of net sales for the year ended September 30, 2021.

We identified the evaluation of the sufficiency of audit evidence obtained over net sales as a critical audit matter. Evaluating the sufficiency of audit evidence obtained over net sales required especially subjective auditor judgment because of the disaggregated nature of the Company’s operations, including revenue recognition accounting policies and procedures that differ among the various subsidiaries and locations. This included determining the Company subsidiaries and locations at which procedures were performed.

The following are the primary procedures we performed to address this critical audit matter. We applied auditor judgment to determine the nature and extent of procedures to be performed over net sales, including the determination of the Company subsidiaries and locations at which those procedures were to be performed. At each Company subsidiary and location where procedures were performed, we:

Assessing the carrying value of goodwill of certain reporting units in the Aerospace & Defense segment

As discussed in Notes 1 and 4 to the consolidated financial statements, the Company reviews goodwill for impairment annually and whenever events or changes in circumstances indicate it is more likely than not that the fair value of a reporting unit is less than its carrying value. The Company uses a discounted cash flow method, using a discount rate determined to be commensurate with the risk inherent in each reporting unit’s business model when estimating fair value.

We identified the assessment of the carrying value of goodwill of certain reporting units in the Aerospace & Defense segment as a critical audit matter. The valuation of each reporting unit involved estimation uncertainty in the projection of future cash flows, resulting in an increased level of subjective auditor judgment. Specifically, subjective and challenging auditor judgment was required to evaluate the forecasted revenue growth rates, gross margins, and discount rates used in the discounted cash flows to derive the fair value of the reporting unit. Evaluation of the forecasted revenue growth rates and gross margins was challenging as they represented subjective determinations of future market and economic conditions that were sensitive to variation. Specialized skills and knowledge were required to evaluate the Company’s discount rate assumptions.

The following were the primary procedures we performed to address this critical audit matter. We evaluated the design and tested the operating effectiveness of certain internal controls over the Company’s goodwill impairment assessment process. This included controls related to the determination of the fair value of the reporting units and the development of forecasted revenue growth rates, gross margins, and discount rates. We evaluated the Company’s forecasted revenue growth rates by comparing to industry and peer company forecasted revenue growth rates. We also assessed the Company’s forecasted revenue growth rates and gross margins by comparing them to historical experience and to underlying business strategies and growth plans available for market participants for each reporting unit. We compared historical forecasted revenue growth rates and gross margins to actual results in order to assess the Company’s ability to forecast. We involved valuation professionals with specialized skills and knowledge, who assisted in evaluating the discount rates by comparing them to discount rate ranges that were independently developed using publicly available market data for comparable entities.

Evaluation of the fair value of acquired intangible assets

As discussed in Note 2 to the consolidated financial statements, the Company acquired I.S.A. – Altanova Group S.r.l., (Altanova) on July 29, 2021 and the assets of Phenix Technologies, Inc. (Phenix) on August 9, 2021. As a result of these transactions, the Company acquired customer relationship intangible assets with a preliminary valuation of $4.3 million and $3.7 million, respectively, and trade name intangible assets with a preliminary valuation of $50.5 million and $9.6 million, respectively (collectively, the intangible assets).

We identified the evaluation of the fair value of these intangible assets acquired in the Altanova and Phenix business combinations as a critical audit matter. A higher degree of subjective auditor judgment was required to evaluate forecasted revenue from existing customers, inclusive of attrition, and the related forecasted cost of sales and operating expenses, discount rate, and the selection of guideline public companies (GPC) assumptions used by the Company to value the customer relationship intangible assets. A higher degree of subjective auditor judgment was also required to evaluate forecasted revenue, royalty rate, and discount rate assumptions used by the Company to value the trade name intangible assets.

The following are the primary procedures we performed to address this critical audit matter. We evaluated the design and tested the operating effectiveness of certain internal controls over the Company’s acquisition-date valuation process, including controls related to the development of the relevant assumptions listed above. We compared the Company’s estimates of forecasted revenues from existing customers, total forecasted revenues and the related forecasted cost of sales and operating expenses to the acquiree’s historical results. We evaluated the Company’s forecasted revenues from existing customers, total forecasted revenues, and forecasted cost of sales and operating expenses by comparing them to those of the Company’s peers and trends in the industry. In addition, we involved valuation professionals with specialized skills and knowledge, who assisted in:
