ITEM 1. BUSINESS

Business Overview and Company History

We are one of the largest providers of highly engineered industrial process heating solutions for process industries. For over 65 years, we have served a diverse base of thousands of customers around the world in attractive and growing markets, including chemical and petrochemical, oil and gas, power generation, commercial, rail and transit, and other, which we refer to as our "key end markets." We offer a full suite of products (heating units, heating cables, temporary power solutions and tubing bundles), services (engineering, installation and maintenance services) and software (design optimization and wireless and network control systems) required to deliver comprehensive solutions to some of the world's largest and most complex projects. With a legacy of innovation and continued investment in research and development, Thermon has established itself as a technology leader in hazardous or classified areas, and we are committed to developing sustainable solutions for our customers. We serve our customers through a global network of sales and service professionals and distributors in more than 30 countries and through our eight manufacturing facilities on three continents. These global capabilities and longstanding relationships with some of the largest multinational oil & gas, chemical processing, power and engineering, procurement and construction ("EPC") companies in the world have enabled us to diversify our revenue streams and opportunistically access high growth markets worldwide.

Thermon, Inc., our principal operating subsidiary in the United States, was founded as a partnership in October 1954 and later incorporated in Texas in 1960. At that time, our primary product was a thermally conductive heat transfer compound invented by our founder, Richard Burdick. Under Mr. Burdick's leadership, we experienced steady growth by diversifying our products and expanding our geographic reach. Mr. Burdick and his family maintained a controlling interest in us until August 2007, when the controlling interest was sold to an affiliate of the Audax Group private equity firm.

On April 30, 2010, an investor group led by entities affiliated with CHS Capital LLC ("CHS") and two other private equity firms, acquired Audax's controlling interest in us.

In May 2011, we completed the initial public offering ("IPO") of our common stock, and our common stock became listed on The New York Stock Exchange under the ticker symbol "THR."

In October 2017, we, through a wholly-owned subsidiary, acquired 100% of the equity interests of CCI Thermal Technologies Inc. and certain related real estate assets for $262.4 million CAD (approximately $204.6 million USD at the exchange rate as of October 30, 2017) in cash. Such subsidiary and CCI Thermal Technologies Inc. combined immediately after the closing of the acquisition to form Thermon Heating Systems, Inc., ("THS"), an indirect, wholly-owned subsidiary of the Company. THS is engaged in industrial process heating, focused on the development and production of advanced heating and filtration solutions for industrial and hazardous area applications and is headquartered in Oakville, Ontario, Canada. In fiscal 2021, we fully integrated the THS legal entity into our legacy Canadian legal entity and consolidated our management and leadership accordingly.

Project Services

As a manufacturer and global expert in process heating solutions, our EPC and end-user customers often times rely on Thermon to deliver a range of project services, which may include:

•Engineering and design;

•Procurement and project management services;

•Turnkey construction installation;

•Recurring facility assessment or audit; and

•Maintenance services.

Our customers rely on Thermon’s design and engineering expertise on projects around the world. These services are combined with our heat tracing and process heating products under one contract to deliver an integrated solution that improves the overall value proposition for the customer. By delivering design drawings in conjunction with early project specifications, we can address our customer needs for design optimization studies, product selection assistance and computer-generated drawing packages. Often these are new facilities or Greenfield projects (which are discussed further below under the section "Customers") but they may also include upgrades or expansions and maintenance projects where our existing customers are upgrading their facilities. Project services are important to our business model and growth strategy to secure Greenfield contracts that both establish and enhance new and existing customer relationships.

Our services are automated by custom software technology. We have invested over years to develop software that assists our experts in the design, specification, and automatic creation of CAD drawings. Our project engineering staff empowered with this software technology can execute the largest projects, including the creation of thousands of drawings, accurately and with efficiency that cannot be matched by manpower alone.

Project services also include full turnkey solutions whereby we contract to install a complete heat tracing or process heating solution. We refer to this as our construction business which is primarily located in the southern United States near many of our customers in the downstream and mid-stream petroleum, chemical and power generation industries.

Manufacturing and Operations

We have eight manufacturing facilities on three continents. We manufacture the majority of our Heat Tracing products at our San Marcos, Texas facility including flexible heating cables, control systems and tubing bundles. The majority of our Process Heating products are manufactured at our four Canadian facilities. Smaller manufacturing locations are located in the Netherlands, Russia and India. We maintain quality control testing standards in all of our manufacturing operations and perform various quality control checks on our products during the manufacturing process. We believe that our highly automated manufacturing process and multiple quality control checkpoints create high levels of operational efficiency.

Our flexible heat cable products are manufactured in San Marcos, Texas. This location includes our electronic cross-linking facility, which we refer to as our "ECLF." Cross-linking enhances the thermal, chemical and electrical stability of our low-temperature self-regulating heater cables. By performing cross-linking in-house, we condense the overall manufacturing cycle by approximately six weeks. This enhances our ability to ensure a high level of product quality and to better control the production process. Core heating cable is distributed to other manufacturing sites, close to the customer base to reduce lead times and satisfy local content requirements.

Our pre-insulated tubing products are manufactured in our facilities in San Marcos and the Netherlands. The majority of our pre-insulated tubing product is custom ordered and made to customers' specifications in a two-part process. The thermal insulation is first applied over the heating cable and process tubing, and a protective plastic outer jacket is extruded onto the bundle to protect the insulation.

Process heating products are fabricated at three facilities in Canada. Our Edmonton facility largely manufactures environmental heating products, and our Orillia facility manufactures tubular heaters, including MI heating cable that is supplied to OEM customers and other Thermon facilities. Our Oakville location specializes in our engineered solutions.

Thermon Power Solutions products are primarily fabricated at a facility in Fort McMurray, Alberta, Canada. Our customer base for Thermon Power Solutions has historically been in the oil sands region of Alberta, Canada, but has expanded its presence in the U.S. Gulf Coast region with the addition of fabrication capacity at our San Marcos, Texas facility.

3

Thermon transportation heating products are fabricated at our facility in Denver, Colorado. This includes both solutions for rail car heating and rail track heating.

Our primary distribution centers are located in San Marcos, Texas, Edmonton, Alberta, the Netherlands and Moscow, Russia. Inventory is typically shipped directly from these distribution centers to customers, the construction site or our regional sales agents or distributors. Our sales agents may maintain "safety stocks" of core products to service the immediate maintenance and repair requirements of customers who are time-sensitive and cannot wait for delivery from one of the central distribution centers. In the United States, a network of agents maintains safety stocks of core products. In Canada, customers are serviced from the three manufacturing locations in Edmonton, Orillia, and Oakville. In Europe, customers are serviced from the central distribution center in the Netherlands. In Asia, safety stock of materials are kept in Yokohama, Japan; Seoul, Korea; Shanghai, China; Pune, India; and Melbourne, Australia. Safety stocks are also warehoused in Moscow, Russia and Mexico City. Thermon aims to have inventory available close to the customer to fulfill urgent needs.

Customers

We serve a broad base of large multinational customers, many of which we have served for more than 60 years. We have a diversified revenue mix with thousands of customers. None of our customers represented more than 10% of total revenue in fiscal 2021.

Customers typically purchase our products when constructing a new facility, which we refer to as "Greenfield projects," or when performing maintenance, repair and operations on a facility's existing heat-traced pipes or upgrading or expanding a current facility, which we refer to collectively as "MRO/UE."

Marketing

Our direct sales force is focused on positioning us with major end-users and EPC companies during the development phase of Greenfield projects with the goal of providing reliable, cost-effective process heating solutions. We utilize a network of more than 100 independent sales agents and distributors in over 30 countries to provide local support to customer facilities for MRO/UE. In addition to focused EPC sales, Thermon is actively engaged in commercial strategies to address a diversified mix of customers in our key end markets. Revenue diversification is a key long-term strategic initiative for the business. We believe that we have established our credibility as a reliable provider of high-quality process heating products. In addition, we believe that our registered trademarks in the United States and numerous additional brand names are recognized globally, giving us excellent brand recognition.

Standards and Certifications

Thermon’s research and development practices ensure our product designs are validated to market requirements and verified to comply with applicable industry standards. We actively participate in the growth and development of the domestic and international electrical standards established in the countries in which we sell products. We continually test our products through a quality control process to demonstrate they can withstand harsh operating environments. They are subjected to various tests, including heat output, thermal stability and long-term aging, with the goal of producing products capable of performing at or beyond the expectations of our customers. All products are further tested and certified for global use by various approval agencies, such as UL, CSA, FM, and ETL, to meet industry leading international standards.

    In order to support the design and development of industrial products rated for operation in potentially hazardous environments, Thermon holds quality system approvals which employ the appropriate oversight requirements. To support the international business, Thermon is audited annually by an Ex Certification Body such as DEKRA, and we hold a Quality Assurance Notification and Quality Assurance Report to IEC/ISO 80079-34. To support the North American business, Thermon is audited quarterly by many nationally recognized test labs including but not limited to UL, CSA, FM, and ETL, to OSHA and Standards Council of Canada requirements. In addition, Thermon also pursues various regional and maritime certifications such as DNV, ABS, EAC, KOSHA and many more. In addition, all of our manufacturing facilities are in certified ISO 9001, which allows us to continue to produce safe, reliable products certified for operating in potentially hazardous environments.

    Over the last three decades, Thermon has made significant investments to actively participate in standardization at the national and international level. We are active in several committees such as the National Electrical Code (NEC), Canadian Electrical Code (CEC), American National Standards Institute (ANSI), National Electrical Equipment Manufacturers Association (NEMA), and the International Electro technical Committee (IEC). We leverage our extensive expertise and knowledge in industrial process heating technology to continually improve the applicable standards of our industry.

Markets

    The major end markets that drive demand for process heating include chemical and petrochemical, up-, mid- and downstream oil and gas, power generation, commercial and rail and transit. We believe there are attractive long-term trends in each of these end markets.

•Chemical and Petrochemical. Process heating is required for temperature maintenance and freeze protection in a variety of chemical processing applications. Factors that may impact process heating demand in chemical and petrochemical end markets include the rapid industrialization of the developing world, a shift in base chemical processing operations to low-cost feedstock regions, a transition of Western chemical processing activities from commodity products to specialty products and environmental compliance.

•Gas. Process heating is in the production and transmission of gas in upstream, midstream, and downstream applications. Gas markets have been resilient over the last twelve months, especially as a feedstock for petrochemical plants, and represent a significant and growing addressable market for our value added solutions. This includes the global and growing market for liquefied natural gas (LNG) compression and regasification facilities.

•Oil. Process heating is used to facilitate the exploration, production, processing, transportation and distribution of oil and oil-based energy products in upstream, midstream, and downstream oil applications. While the demand forecast for oil can be unpredictable, e.g. the COVID impact on transportation fuels, we have a sizable installed base that provides recurring MRO/UE revenue, especially in the downstream refining market.

•Power Generation. Process heating is required for high-temperature product maintenance, freeze protection and environmental regulation compliance in coal and gas facilities and for safety systems in nuclear facilities. An important driver of demand for process heating solutions for power generation is increasing demand for electricity worldwide, with an increasing prevalence of renewable power generation solutions.

•Rail and Transit. Process heating is required to safely clear and heat rail switches, melt snow and ice from platforms, and provide comfort heating and defrosting in rolling stock. With over 1.1 million kilometers of operational railway in the world, rail is still one of the most economical and safe solutions for passengers and products globally.

•Commercial. Process heating is required for hospitals, hospitality/lodging, universities and secondary education, and light industrial facilities to provide freeze protection, temperature regulation, process control, and supporting laboratory environments. The electrification of heating products and removal of combustion-based heating solutions in urban areas drives demand for our products.

•Other. We serve a growing number of other markets where we add value for customers, such as data centers, food and beverage, mineral processing, pharmaceutical, semiconductor facilities and other general industrial activities.

Our ability to provide technology design, such as wireless network controls and design software is an increasing factor in our customers' decision to purchase our products.

Segments

    We operate in four reportable segments based on four geographic countries or regions in which we operate: (i) United States and Latin America ("US-LAM"), (ii) Canada, (iii) Europe, Middle East and Africa ("EMEA") and (iv) Asia-Pacific ("APAC"). Profitability within our segments is measured by operating income. See Note 19, "Segment Information" for financial data relating to our four reportable geographic segments.

Competition

    The global industrial electric heat tracing industry is fragmented and consists of more than 30 companies, which typically only serve discrete local markets and provide a limited service offering. We believe that we are the second largest participant in the industrial electric heat tracing market and one of only a few solution providers with a comprehensive suite of products and services, global capabilities, and industry-leading controls technology, which includes our design software products. Our most significant competitor is the thermal management segment of nVent Electric plc (NYSE: NVT).

5

    Following the THS acquisition in October 2017, we entered the broader industrial process heating market. The industrial process heating market, which includes industrial heat tracing, tends to be fairly fragmented with several smaller companies serving discrete local markets with limited offerings. Our competitors vary by end-market, but generally we view nVent Electric, NIBE, Watlow and Spirax Sarco as competitors in various areas across the spectrum of end-markets we now serve.

Industrial process heating providers differentiate themselves through value-added services, long-term customer relationship management and the ability to provide a full range of solutions. We differentiate ourselves from local providers by maintaining a global footprint, a full suite of products and services and a track record with some of the largest multinational energy, chemical processing, power and EPC companies in the world. In addition, we are almost entirely dedicated to providing thermal solutions and complementary products and services whereas some of our competitors' thermal solutions operations constitute only one of numerous operating segments.

Intellectual Property and Technology

The industrial process heating industry, as well as the complementary markets where we intend to expand, are highly competitive and subject to the introduction of innovative techniques and services using new technologies. While we have patented some of our products and processes, we historically have not relied upon patents to protect our design, manufacturing processes or products, and our patents are not material to our operations or business. Instead, we rely significantly on maintaining the confidentiality of our trade secrets, manufacturing know-how, other proprietary rights and other information related to our operations. Accordingly, we require all employees to sign a nondisclosure agreement to protect our trade secrets, business strategy and other proprietary information. We rely on registered and unregistered trademarks in the United States and abroad and have many recognized brand names.

Our research and development activities are focused on identifying new technologies to enhance our industrial process heating solutions and meet the evolving needs of our customers. This maximizes safety and product reliability and reduces the customer's total cost of ownership, which consists of capital expenses, maintenance costs and energy costs. Current product development initiatives include polymer research and continued advancement of integrated control and monitoring systems. Software development activities include advanced heat tracing network monitoring communication software and engineering design software initiatives.

Resources

Our critical raw materials include polymers, graphite, copper and stainless steel. For most of these materials, we purchase from multiple suppliers in order to avoid any potential disruption of our manufacturing operations. For a small number of raw material items that require specific quality specifications, we have single source supply arrangements. We manage the inherent supply risk through purchase contracts and the maintenance of increased safety stock levels at all times. We evaluate pricing and performance of all suppliers annually. For our low-volume custom-built electronic controller components, we select a single supplier based on past performance reliability and monitor the process closely as volumes are too low to divide this product over multiple suppliers. Approximately 60% of the components we purchase by cost are off-the-shelf items and are readily available from multiple sources. Our purchase specifications are usually based on industry or manufacturer standards. Testing of the raw materials is performed and documented by our suppliers and is reviewed by us at the time of receipt. While our manufacturing locations are predominantly in North America, we operate an “in the region, for the region” strategy to diversify our supplier base, manage costs and hold inventory across our various sites. We employ a screening mechanism for conflict materials as part of our supplier approval and management processes. Use of tin, tungsten, tantalum and gold (3TG) in our purchased components is very minimal. We have established a process to collect and report conflict minerals use in order to meet all regulatory and customer requirements. We use limited amounts of magnesium, graphite and platinum in our processes and these commodities are sourced from multiple suppliers to ensure availability. The quantities we consume of these materials are insignificant compared to the global production and usage.

Government Contracts

We do not have any material portion of our business that may be subject to renegotiation of profits or termination of contracts or subcontracts at the U.S. government's election.

Government Regulation

Due to the international scope of our operations, we are subject to complex United States and foreign laws governing, among others, anti-corruption matters, export controls, economic sanctions, anti-boycott rules, currency exchange controls and

6

transfer pricing rules. These laws are administered by, among others, the U.S. Department of Justice, the SEC, the Internal Revenue Service, or the "IRS," Customs and Border Protection, the Bureau of Industry and Security, or "BIS," the Office of Antiboycott Compliance, or "OAC," and the Office of Foreign Assets Control, or "OFAC," as well as the counterparts of these agencies in foreign countries. Our policies mandate compliance with these laws. Despite our training and compliance programs, no assurances can be made that we will be found to be operating in full compliance with, or be able to detect every violation of, any such laws. We cannot predict the nature, scope or effect of future regulatory requirements to which our international operations might be subject or the manner in which existing laws might be administered or interpreted.

In addition, our operations and properties are subject to a variety of federal, state, local and foreign environmental laws and regulations, including those governing the discharge of pollutants into the air or water, the management and disposal of hazardous substances or wastes, the cleanup of contaminated sites, the emission of greenhouse gases, and workplace health and safety. Certain environmental laws, including the Comprehensive Environmental Response, Compensation, and Liability Act, impose joint and several liability for cleanup costs, without regard to fault, on persons who have disposed of or released hazardous substances into the environment. In addition, we could become liable to third parties for damages resulting from the disposal or release of hazardous substances into the environment. Some of our sites are affected by soil and groundwater contamination relating to historical site operations, which could require us to incur expenses to investigate and remediate the contamination in compliance with environmental laws. Some of our operations require environmental permits and controls to prevent and reduce air and water pollution, and these permits are subject to modification, renewal and revocation by issuing authorities. A failure to obtain, maintain, and comply with these permit requirements could result in substantial penalties, including facility shutdowns. From time to time, we could be subject to requests for information, notices of violation, and/or investigations initiated by environmental regulatory agencies relating to our operations and properties. Violations of environmental and health and safety laws can result in substantial penalties, civil and criminal sanctions, permit revocations, and facility shutdowns. Environmental and health and safety laws may change rapidly and have tended to become more stringent over time. As a result, we could incur costs for past, present, or future failure to comply with all environmental and health and safety laws and regulations. In addition, we could become subject to potential regulations concerning the emission of greenhouse gasses, and while the effect of such future regulations cannot be determined at this time, they could require us to incur substantial costs in order to achieve and maintain compliance. In the ordinary course of business, we may be held responsible for any environmental damages we may cause to our customers' premises.

Other than our compliance requirements with environmental regulations, compliance with other government regulations has not had, and based on laws and regulations currently in effect, is not expected to have a material effect on the Company's capital expenditures, earnings or competitive position. See section titled Risk Factors for additional information on government regulation that could impact our business.

Human Capital Management

We believe that our people are one of our most important investments and greatest assets. The success and the growth of our business depend on our ability to attract, develop, incent and retain a diverse population of talented, qualified and highly skilled employees at all levels of our organization, including our executive officers, and across our global workforce. Our culture enables us to achieve our vision to be the world leader in industrial process heating. At the heart of our culture are our core values of Care, Commit and Collaborate.

Our Board of Directors (the "Board") provides important oversight on certain human capital matters. The Human Capital Management and Compensation Committee of the Board maintains oversight over our strategic direction for various people-related business strategies, including our compensation and benefit programs, leadership succession planning, culture, diversity, equity and inclusion, and talent development programs. The Company’s management proactively manages our human capital and cares for our employees in a manner that is consistent with our values.

Employee Health and Safety

We believe nothing is more important than the health, safety, and well-being of our people. We work hard to achieve best in class levels of safety through the application of policies and best practices. We maintain a robust safety culture to reduce workplace injuries, supported by effective communication, reporting, and external benchmarking. We hold regular talks and events on key safety topics, including reporting all injuries, hazards, near-misses, and case management to prevent reoccurrence. We also participate in industry groups, within and outside the manufacturing, construction, and energy sectors, to share safety best practices and collaborate to address safety concerns.

Our Safety Record

7

Any loss of life or serious injury in the workplace is unacceptable. We did not have any fatal incidents at any of our facilities or job sites in fiscal 2021. We primarily track two key safety indicators in monitoring our safety efforts, total recordable incident rate (“TRIR”) and lost-time incident rate (“LTIR”). Our TRIR decreased from 0.19 in fiscal 2020 to 0.07 in fiscal 2021 and our LTIR decreased from 0.05 in fiscal 2020 to 0.00 in fiscal 2021. We are proud of our superior safety rating in both the manufacturing and construction industries. TRIR & LTIR is defined as the Company’s number of recordable injuries/loss time, respectively, experienced by employees during the fiscal year multiplied by 200,000 divided by the number of man hours worked during the fiscal year.

In addition to TRIR and LTIR, we also measure total near miss and hazard ID reporting as well as case management metrics. These aid in accident prevention, which we believe is critical to incident avoidance and again supports our superior safety rating in the industry.

COVID-19 Response

Throughout fiscal 2021 and during the pandemic, we remained operational in order to support our customers while still supporting and protecting our employees. At the beginning of the COVID-19 pandemic, we immediately mobilized our office employees to a work-from-home environment and ensured that our essential manufacturing and field construction employees were kept safe with proper personal protective equipment ("PPE"). In addition, we deployed new safety policies and guidelines based on recommendations from the World Health Organization, the Centers for Disease Control and Prevention, as well as local health organizations. Our ability to ensure business continuity and employee welfare and safety was the result of the Company’s early planning, and a well-designed enterprise business continuity plan. This plan was led by our Critical Response Team, which is comprised of senior leadership who collaborated with designated site leaders around the globe to implement COVID-19 specific polices and guidelines that addressed the regional requirements of the population. Our COVID-19 related policies and guidelines (which vary by country and region of operation) include, but are not limited to:

a.Time off and pay continuation for immune compromised essential workers in the early weeks of the pandemic

b.Work-from-home policy for office employees

c.Guidelines for appropriate use and application of personal protective equipment

d.Guidelines and recommendations for social distancing and increased hygiene methods; and

e.Contact tracing and quarantine protocols specific to each location.

Workforce Breakdown

On March 31, 2021, we employed approximately 1,083 regular employees, of which 37.2% were located in the U.S. and Latin America, 35.1% in Canada, 13.1% located in Europe, the Middle East, and Africa ("EMEA"), and 14.6% located in Asia-Pacific ("APAC"). Our 12-month rolling voluntary turnover rate as of March 31, 2021 was 12.6% compared to the 2020 manufacturing industry average of 12% according to Aon 2020 Salary Increase and Turnover Study – Second Edition. Approximately 1.1% of our global employees are covered by a collective bargaining agreement. We have not experienced any union-related work stoppages in the past, and we believe that our working relationship with our employees is generally very good.

Diversity, Equity, and Inclusion

We believe in the benefits of an inclusive workforce, where diverse backgrounds are represented, engaged, and empowered to inspire innovative ideas and decisions. We have locations in 15 countries, and our employees operate across cultures, functions, unique languages, and time zones to solve the technical and logistical challenges presented by a worldwide customer base. Our diversity statistics include the following as of March 31, 2021 (based on self-reporting at the date of hire): 25.0% of our employees worldwide identify as females (excludes certain employees in Europe in accordance with the European Union’s General Data Protection Regulation); 21.8% of our employees in the United States identify as female; and 31.8% of our employees in the United States identify as a racial or ethnic minority.

In fiscal year 2021, we launched several initiatives to foster diversity in our organization. These initiatives include: (i) launching of a new global job posting platform that allows us to source a wider pool of candidates, (ii) updating master service agreements with external recruiting partners and temporary agencies in the United States to include specific service level agreements to source more diverse slates of talent for positions these partners and agencies are tasked to fill, and (iii) targeting diversity in our university recruiting for our U.S. new hire graduate program for sales engineers which resulted in over half of recent hires coming from diverse groups in fiscal 2021.

8

We know we have more to do when it comes to increasing the representation of historically underrepresented groups within our global workforce, and we are taking action to ensure Thermon is an employer of choice for diverse candidates.

Compensation and Benefits

We provide competitive compensation and benefits programs to help meet the needs of our employees and to attract and retain talent. In addition to salaries, these programs (which vary by country and region) include annual bonuses for all regular full and part time employees globally, a 401(k) Plan, healthcare and insurance benefits, health savings and flexible spending accounts, paid time off, flexible work schedules, employee assistance programs, tuition assistance, and scholarship programs for children and grandchildren of employees.

Reward decisions are informed by the annual performance evaluation process which includes an assessment of both Thermon’s values demonstrated by the employee and the delivery of employee-specific goals. In addition to our broad-based programs, we have used targeted equity-based grants with vesting conditions to facilitate retention of key personnel, particularly those with critical domain expertise necessary to deliver on the long-term strategic initiatives of the Company.

ITEM 1A. Risk Factors

The following risk factors address the material risks concerning our business. If any of the risks discussed in this annual report were to occur, our business, prospects, financial condition, results of operations and our ability to service our debt could be materially and adversely affected and the trading price of our common stock could decline significantly. Some statements in this annual report, including statements in the following risk factors, constitute forward-looking statements. Please refer to the section entitled "Forward-Looking Statements."

Risks Related to Our Business and Industry

Macroeconomic and Industry Risks

The outbreak of a global pandemic, including the current pandemic caused by the novel strain of coronavirus (COVID-19), and the measures taken in response thereto could have an adverse effect on our business, results of operations and financial condition.

Our business, financial condition, results of operations and cash flows may be adversely affected if a global pandemic, including the COVID-19 pandemic, interferes with the ability of our employees, vendors and customers to perform our and their respective responsibilities and obligations relative to the conduct of our business. The COVID-19 coronavirus pandemic has caused significant volatility in the global economy. Public health problems resulting from COVID-19 and safety measures instituted by governments and businesses to mitigate its spread, including travel restrictions and quarantines, could continue to contribute to a general slowdown in the global economy, adversely impact the businesses of our customers, suppliers and distribution partners, and disrupt our operations. For example, precautionary measures instituted by government authorities and sanitization procedures adopted to protect our employees in response to the COVID-19 pandemic have required us to temporarily suspend operations at certain of our manufacturing facilities.

Changes in our operations around the world in response to COVID-19 or employee illnesses resulting from the pandemic may result in inefficiencies or delays, including delays in sales and product development efforts, delays to our strategic plans, and additional costs related to business continuity initiatives, that cannot be fully mitigated through succession planning, employees working remotely or teleconferencing technologies. In addition, changes in the operations of our suppliers in response to COVID-19 may also result in disruptions in our manufacturing and supply arrangements caused by the loss or disruption of essential manufacturing and supply elements such as raw materials or other finished product components, transportation, workforce or other manufacturing and distribution capability. Finally, COVID-19 could negatively affect our internal controls over financial reporting as a portion of our workforce is required to work from home, potentially requiring new processes, procedures, and controls.

A prolonged economic downturn due to the COVID-19 pandemic could result in reduced demand for our products and services. The severity and longevity of the COVID-19 pandemic may cause customers to suspend their decisions on using our products and/or services and give rise to significant changes in regional and global economic conditions that could delay or interfere with the capital spending of our customers. While the full extent and continued impact of the pandemic and the efficacy and availability of vaccines cannot be reasonably estimated at this time, it could have a material impact on our consolidated business, results of operations and financial condition in our fiscal year ending March 31, 2022 and beyond. The COVID-19 pandemic could also have the effect of heightening other risks described elsewhere in these Risk Factors.

The markets we serve are subject to general economic conditions and cyclical demand, which could harm our business and lead to significant shifts in our results of operations from quarter to quarter that make it difficult to project long-term performance.

Our operating results have been and may in the future be adversely affected by general economic conditions and the cyclical pattern of certain industries in which our customers and end-users operate. Demand for our products and services depends in large part upon the level of capital and maintenance expenditures by many of our customers and end-users, in particular those in the energy, chemical processing and power generation industries, and firms that design and construct facilities for these industries. These customers' expenditures historically have been cyclical in nature and vulnerable to economic downturns. Prolonged periods of little or no economic growth could decrease demand for oil and gas which, in turn, could result in lower demand for our products and a negative impact on our results of operations and cash flows. In addition, this historically cyclical demand may lead to significant shifts in our results of operations from quarter to quarter, which limits our ability to make accurate long-term predictions about our future performance.

10

Suspensions and delays in large capital projects within the energy sector, especially in the United States and Canada, have adversely affected our results of operations in recent years. A sustained downturn in the energy industry, due to decreases in oil and gas prices or demand for oil and gas products, could further decrease demand for some of our products and services and adversely affect our business, financial condition and results of operations.

A significant portion of our revenue historically has been generated by end-users in the oil and gas markets where we serve all three major categories of customers in the petroleum industry - upstream exploration/production, midstream transportation and downstream refining. The businesses of most of our customers in the energy industry are, to varying degrees, cyclical and historically have experienced periodic downturns. Profitability in the energy industry is highly sensitive to supply and demand cycles and commodity prices, which historically have been volatile, and our customers in this industry have tended to delay large capital projects, including expensive maintenance and upgrades, during industry downturns. Customer project delays and cancellations may limit our ability to realize value from our backlog as expected and cause fluctuations in the timing or the amount of revenue earned and the profitability of our business in a particular period. In addition, such delays and cancellations may lead to significant fluctuations in results of operations from quarter to quarter, making it difficult to predict our financial performance on a quarterly basis.

Demand for a significant portion of our products and services depends upon the level of capital expenditure by companies in the energy industry, which depends, in part, on energy prices, which can be volatile. In recent years, we have experienced suspensions or delays in large capital projects within the energy sector, especially in the upstream exploration and production sector, and most notably in the United States and Canada. The impact on oil and gas commodity markets has further been impacted by the reduction in demand caused by the public safety measures instituted by governments and businesses to mitigate the spread of COVID-19. A sustained downturn in the capital expenditures of our customers, whether due to a decrease in the market price of oil and gas or demand for oil and gas products, may delay projects, decrease demand for our products and services and cause downward pressure on the prices we charge, which, in turn, could have an adverse effect on our business, financial condition and results of operations. Such downturns, including the perception that they might continue, could also have a significant negative impact on the market price of our common stock.

As a global business, we are exposed to economic, political and other risks in a number of countries, which could materially reduce our revenues, profitability, cash flows, or materially increase our liabilities. If we are unable to continue operating successfully in one or more foreign countries, it may have an adverse effect on our business and financial condition.

For fiscal 2021, approximately 65% of our revenues were generated outside of the United States, and approximately 33% were generated outside of North America. One of our key growth strategies is to continue to expand our global footprint in emerging and high growth markets around the world; however, we may be unsuccessful in expanding our international business.

Conducting business outside the U.S. subjects us to additional risks that may impact our revenues, profitability or cash flows or increase our liabilities, including the following:

•changes in a specific country's or region's political, social or economic conditions, particularly in emerging markets;

•changes in trade relations between the United States and those foreign countries in which our customers and suppliers operate, including protectionist measures such as tariffs, import or export licensing requirements and trade sanctions;

•restrictions on our ability to own or operate subsidiaries in, expand in and, if necessary, repatriate cash from, foreign jurisdictions;

•exchange controls and currency restrictions;

•the burden of complying with numerous and potentially conflicting legal requirements;

•potentially negative consequences from changes in U.S. and foreign tax laws;

•difficulty in staffing and managing (including ensuring compliance with internal policies and controls) geographically widespread operations;

•different regulatory regimes controlling the protection of our intellectual property;

•difficulty in the enforcement of contractual obligations in non-U.S. jurisdictions and the collection of accounts receivable from foreign accounts; and

•transportation delays or interruptions.

One or more of these factors could prevent us from successfully expanding our presence in international markets, could have an adverse effect on our revenues, profitability or cash flows or cause an increase in our liabilities. We may not succeed in developing and implementing policies and strategies to counter the foregoing factors effectively in each location where we do business. In addition, the imposition of trade restrictions, economic sanctions or embargoes by the United States or foreign governments could adversely affect our future sales and results of operations.

11

Business Risks

Our backlog may fluctuate and a failure to deliver our backlog on time could affect our future sales, profitability and our relationships with our customers, and if we were to experience a material amount of modifications or cancellations of orders, our sales could be negatively impacted.

Our backlog is comprised of the portion of firm signed purchase orders or other written contractual commitments received from customers that we have not recognized as revenue. Backlog may increase or decrease based on the addition of large multi-year projects and their subsequent completion. Backlog may also be favorably or unfavorably affected by foreign currency rate fluctuations. The dollar amount of backlog as of March 31, 2021 was $114.2 million. The timing of our recognition of revenue out of our backlog is subject to a variety of factors that may cause delays, many of which, including fluctuations in our customers' delivery schedules, are beyond our control and difficult to forecast. Such delays may lead to significant fluctuations in results of operations from quarter to quarter, making it difficult to predict our financial performance on a quarterly basis. Further, while we have historically experienced few order cancellations and the amount of order cancellations has not been material compared to our total contract volume, if we were to experience a significant amount of cancellations of or reductions in purchase orders, it would reduce our backlog and, consequently, our future sales and results of operations.

Our ability to meet customer delivery schedules for our backlog is dependent on a number of factors including, but not limited to, access to raw materials, an adequate and capable workforce, engineering expertise for certain projects, sufficient manufacturing capacity and, in some cases, our reliance on subcontractors. The availability of these factors may in some cases be subject to conditions outside of our control. A failure to deliver in accordance with our performance obligations may result in financial penalties and damage to existing customer relationships, our reputation and a loss of future bidding opportunities, which could cause the loss of future business and could negatively impact our future sales and results of operations.

Our future revenue depends in part on our ability to bid and win new contracts. Our failure to effectively obtain future contracts could adversely affect our profitability.

Our future revenue and overall results of operations require us to successfully bid on new contracts and, in particular, contracts for large Greenfield projects, which are frequently subject to competitive bidding processes. Our revenue from major projects depends in part on the level of capital expenditures in our principal end markets, including the energy, chemical processing and power generation industries. With the recent disruptions to many of our customers’ end markets caused by the COVID-19 pandemic and the recent volatility in oil and gas commodity markets, we anticipate we could experience decreased levels of profitability which could adversely impact our financial results. In addition, if we fail to replace completed or canceled large Greenfield projects with new order volume of the same magnitude, our backlog will decrease and our future revenue and financial results may be adversely affected. The number of such projects we win in any year fluctuates, and is dependent upon the number of projects available and our ability to bid successfully for such projects. Contract proposals and negotiations are complex and frequently involve a lengthy bidding and selection process, which is affected by a number of factors, such as competitive position, market conditions, financing arrangements and required governmental approvals. For example, a client may require us to provide a bond or letter of credit to protect the client should we fail to perform under the terms of the contract. If negative market conditions continue, or if we fail to secure adequate financial arrangements or required governmental approvals, we may not be able to pursue particular projects, which could adversely affect our profitability.

Our current or future indebtedness could impair our financial condition and reduce the funds available to us for other purposes. Our debt agreements impose certain operating and financial restrictions, with which failure to comply could result in an event of default that could adversely affect our results of operations.

We have substantial indebtedness. At March 31, 2021, we had $148.5 million of outstanding indebtedness. If our cash flows and capital resources are insufficient to fund the interest payments on our outstanding borrowings under our credit facility and other debt service obligations and keep us in compliance with the covenants under our debt agreements or to fund our other liquidity needs, we may be forced to reduce or delay capital expenditures, sell assets or operations, seek additional capital or restructure or refinance our indebtedness. We cannot guarantee that we would be able to (i) take any of these actions or that these actions would permit us to meet our scheduled debt service obligations or that these actions would be permitted under the terms of our existing or future debt agreements, which may impose significant operating and financial restrictions on us and could adversely affect our ability to finance our future operations or capital needs; (ii) obtain standby letters of credit, bank guarantees or performance bonds required to bid on or secure certain customer contracts; (iii) make strategic acquisitions or investments or enter into alliances; (iv) withstand a future downturn in our business or the economy in general; (v) engage in

12

business activities, including future opportunities, that may be in our interest; and (vi) plan for or react to market conditions or otherwise execute our business strategies.

If we cannot make scheduled payments on our debt, or if we breach any of the covenants in our debt agreements, we will be in default under such agreements and, as a result, our debt holders could declare all outstanding principal and interest to be due and payable, the lenders under our credit facility could terminate their commitments to lend us money and foreclose against the assets securing our borrowings, and we could be forced into bankruptcy or liquidation.

In addition, we and certain of our subsidiaries may incur significant additional indebtedness, including additional secured indebtedness. Although the terms of our debt agreements contain restrictions on the incurrence of additional indebtedness, these restrictions are subject to a number of qualifications and exceptions, and additional indebtedness incurred in compliance with these restrictions could be significant. Incurring additional indebtedness could increase the risks associated with our substantial indebtedness, which may impact our ability to meet our debt service obligations.

Additional liabilities related to taxes, potential tax adjustments or changes to tax policy in foreign jurisdictions could adversely impact our financial results, financial condition and cash flows.

We are subject to tax and related obligations in the jurisdictions in which we operate or do business, including state, local, federal and foreign taxes. The taxing laws of the various jurisdictions in which we operate or do business often are complex and subject to varying interpretations. Tax authorities may challenge tax positions that we take or historically have taken, and may assess taxes where we have not made tax filings or may audit the tax filings we have made and assess additional taxes, as they have done from time to time. Some of these assessments may be substantial, and may involve the imposition of substantial penalties and interest. Significant judgment is required in evaluating our tax positions and in establishing appropriate reserves. The resolutions of our tax positions are unpredictable. The payment of substantial additional taxes, penalties or interest resulting from any assessments could adversely impact our results of operations, financial condition and cash flows.

If we are unable to successfully develop and improve our products and successfully implement new technologies in the markets that we serve, our business and results of operations could be adversely affected.

Our future success will depend upon our continued investment in research and development of new products, improvement and enhancement of our existing product offerings and our ability to continue to achieve new technological advances in the process heating industry. Our inability to continue to successfully develop and market new products or our inability to implement technological advances on a pace consistent with that of our competitors could adversely affect our business and results of operations.

We may be unable to compete successfully in the highly competitive markets in which we operate.

We operate in domestic and international markets and compete with highly competitive domestic and international manufacturers and service providers. The fragmented nature of the industrial heat tracing industry and the similarly fragmented nature of the industrial process heating industry makes the market for our products and services highly competitive. A number of our direct and indirect competitors are major multinational corporations, some of which have substantially greater technical, financial and marketing resources, and additional competitors may enter these markets at any time. In addition, we compete against many regional and lower-cost manufacturers. Our competitors may develop products that are superior to our products, develop methods of more efficiently and effectively providing products and services, adapt more quickly than we do to new technologies or evolving customer requirements, or attempt to compete based primarily on price, localized expertise and local relationships. If we are unable to continue to differentiate our products and services or if we experience an increase in competition, it may cause us to lose market share or compel us to reduce prices to remain competitive, which could result in a reduction in our revenues and results of operations.

Our gross margins depend, in part, on our revenue mix. Although Greenfield project revenues, which provide for an ongoing stream of future high-margin MRO/UE revenues, are critical to our success and growth, increased Greenfield project revenues can adversely affect our gross margin.

Typically, both Greenfield and MRO/UE customers require our products as well as our engineering and construction services. We tend to experience lower margins from our design optimization, engineering, installation and maintenance services than we do from sales of our heating cable, tubing bundle and control system products. We also tend to experience lower margins from our outsourced products, such as electrical switch gears and transformers, than we do from our manufactured products. Accordingly, our gross margins are impacted by our mix of products and services. Although our product mix varies from period to period due to a variety of factors, during fiscal year ended March 31, 2021, Greenfield revenue accounted for

13

approximately 35% of our total revenue. Although Greenfield project revenues, which provide for an ongoing stream of future high-margin MRO/UE revenues, are critical to our long-term success and growth, a revenue mix higher in lower-margin Greenfield project revenues relative to historical levels could adversely affect our gross margins and results of operations.

Our business strategy includes growth and product diversification through strategic acquisitions. These acquisitions and investments could be unsuccessful or consume significant resources, which could adversely affect our results of operations.

Acquisitions and investments may involve cash expenditures, debt incurrence, operating losses and expenses that could have an adverse effect on our financial condition and results of operations. Acquisitions involve numerous other risks, including:

•diversion of management time and attention from daily operations;

•difficulties integrating acquired businesses, technologies and personnel into our business;

•difficulties in realization of expected synergies and revenue creation or cross-selling opportunities;

•potential loss of key employees, key contractual relationships or key customers of acquired companies or of us; and

•assumption of the liabilities and exposure to unforeseen liabilities of acquired companies.

We have limited experience in acquiring or integrating other businesses or making investments or undertaking joint ventures with others. It may be difficult for us to complete transactions quickly and to integrate acquired operations efficiently into our current business operations. It may also be difficult for us to identify suitable acquisition candidates, which may inhibit our growth rate. Any acquisitions or investments may ultimately harm our business or financial condition if they are unsuccessful and any acquisitions or investments ultimately result in impairment charges.

We carry insurance against many potential liabilities, but our management of risk may leave us exposed to unidentified or unanticipated risks.

Although we maintain insurance policies with respect to our related exposures, including certain casualty, property and business interruption programs, these policies contain deductibles, self-insured retentions and limits of coverage. In addition, we may not be able to continue to obtain insurance at commercially reasonable rates or may be faced with liabilities not covered by insurance, such as, but not limited to, environmental contamination or terrorist attacks. We estimate our liabilities for known claims and unpaid claims and expenses based on information available as well as projections for claims incurred but not reported. However, insurance liabilities, some of which are self-insured, are difficult to estimate due to various factors. If any of our insurance policies or programs are not effective in mitigating our risks, we may incur losses that are not covered by our insurance policies, that are subject to deductibles or that exceed our estimated accruals or our insurance policy limits, which could adversely impact our business and results of operations.

Volatility in currency exchange rates may adversely affect our financial condition, results of operations or cash flows.

We may not be able to effectively manage our exchange rate and/or currency transaction risks. Volatility in currency exchange rates may decrease our revenue and profitability, adversely affect our liquidity and impair our financial condition. While we have entered into hedging instruments to manage our exchange rate risk as it relates to certain intercompany balances with certain of our foreign subsidiaries, these hedging activities do not eliminate exchange rate risk, nor do they reduce risk associated with total foreign sales.

Our non-U.S. subsidiaries generally sell their products and services in the local currency, but obtain a significant amount of their products from our facilities located elsewhere, primarily the United States, Canada or Europe. In particular, significant fluctuations in the Canadian Dollar, the Russian Ruble, the Euro or the Pound Sterling against the U.S. Dollar could adversely affect our results of operations. During fiscal 2021 and 2020, the value of the U.S. Dollar overall strengthened in relation to the principal non-U.S. currencies from which we derive revenue, which negatively impacted revenue by $1.7 million and $5.0 million, respectively. Any further appreciation in the U.S. Dollar relative to such non-U.S. currencies could continue to have a significant negative impact on our results of operations in future periods. We also bid for certain foreign projects in U.S. Dollars or Euros. If the U.S. Dollar or Euro strengthen relative to the value of the local currency, we may be less competitive in bidding for those projects. In addition, currency variations can adversely affect margins on sales of our products in countries outside of the U.S. and margins on sales of products that include components obtained from suppliers located outside of the U.S. See Item 7A, "Quantitative and Qualitative Disclosures about Market Risk" for additional information regarding our foreign currency exposure relating to operations.

14

Because our consolidated financial results are reported in U.S. Dollars and we generate a substantial amount of our sales and earnings in other currencies, the translation of those results into U.S. Dollars can result in a significant decrease in the amount of those sales and earnings. Fluctuations in currencies relative to the U.S. Dollar may make it more difficult to perform period-to-period comparisons of our reported results of operations. In addition, the net asset values of foreign operations are adjusted upward and downward based on currency exchange rate fluctuations and are reported in our foreign currency translation adjustment as part of other comprehensive income in our consolidated statements of operations and comprehensive income/(loss).

We have significant goodwill and other intangible assets and future impairment of our goodwill and other intangible assets could have a material negative impact on our financial results.

    We test goodwill and indefinite-life intangible assets for impairment on an annual basis, and more frequently if circumstances warrant, by comparing the estimated fair value of each of our reporting units to their respective carrying values. As of March 31, 2021, our goodwill and other intangible assets balance was $316.8 million, which represented 51% of our total assets. Long-term declines in projected future cash flows could result in future goodwill and other intangible asset impairments. Because of the significance of our goodwill and other intangible assets, any future impairment of these assets could have a material adverse effect on our financial results.

If we lose our senior management or other key employees or cannot successfully execute succession plans, our business may be adversely affected.

Competition for qualified management and key technical and sales personnel in our industry is intense. Our ability to successfully operate and grow our global business and implement our strategies is largely dependent on the efforts, abilities and services of our senior management and other key employees. If we lose the services of our senior management or other key employees for any reason and are unable to timely find and secure qualified replacements with comparable experience in the industry, our business could be negatively affected.

We rely heavily on trade secrets to gain a competitive advantage in the market and the unenforceability of our nondisclosure agreements may adversely affect our operations.

The heat tracing industry is highly competitive and subject to the introduction of innovative techniques and services using new technologies. We rely significantly on maintaining the confidentiality of our trade secrets and other information related to our operations. Accordingly, we require all employees to sign a nondisclosure agreement to protect our trade secrets, business strategy and other proprietary information. If the provisions of these agreements are found unenforceable in any jurisdiction in which we operate, the disclosure of our proprietary information may place us at a competitive disadvantage. Even where the provisions are enforceable, the confidentiality clauses may not provide adequate protection of our trade secrets and proprietary information in every such jurisdiction and our trade secrets and proprietary information could be compromised as a result.

Intellectual property challenges may hinder our ability to develop, engineer and market our products, and we may incur significant costs in our efforts to successfully avoid, manage, defend and litigate intellectual property matters.

Patents, non-compete agreements, proprietary technologies, trade secrets, customer relationships, trademarks, trade names and brand names are important to our business. Intellectual property protection, however, may not preclude competitors from developing products similar to ours or from challenging our trade names or products. Our pending patent applications and our pending copyright and trademark registration applications may not be allowed or competitors may challenge the validity or scope of our patents, copyrights or trademarks. In addition, our patents, copyrights, trademarks and other intellectual property rights may not provide us a significant competitive advantage, particularly in those countries where the laws do not protect our intellectual property rights as fully as in the United States. Participants in our markets may use challenges to intellectual property as a means to compete. Patent and trademark challenges increase our costs to develop, engineer and market our products. We may need to spend significant resources monitoring our intellectual property rights and we may or may not be able to detect infringement by third parties. If we fail to successfully enforce our intellectual property rights or register new patents, our competitive position could suffer, which could have a material adverse effect on our business, financial condition, results of operations and cash flows.

In addition, while we have not faced intellectual property infringement claims from others in recent years, any dispute or litigation involving intellectual property could be costly and time-consuming due to the complexity and the uncertainty of intellectual property litigation. Our intellectual property portfolio may not be useful in asserting a counterclaim, or negotiating a license, in response to a claim of infringement or misappropriation. In addition, as a result of such claims, we may lose our

15

rights to utilize critical technology, may be required to pay substantial damages or license fees with respect to the infringed rights or may be required to redesign our products at a substantial cost, any of which could have a material adverse effect on our business, financial condition, results of operations and cash flows.

Operational Risks

Breaches of our information technology systems could occur that materially damage business partner and customer relations and subject us to significant reputational, financial, legal and operational consequences.

    As a company we store company, customer, employee and business partner information, which may include, among other information, trade secrets, names, addresses, phone numbers, email addresses, tax identification numbers, payment account information and customer facility information. We could be subject to sophisticated and targeted attacks attempting to obtain unauthorized access to confidential information, destroy data, disrupt or degrade service, sabotage systems or cause other damage, including via the introduction of computer viruses or malware and cyber-attacks. These attacks are constantly evolving in nature, increasing the efforts and controls required to prevent, detect and defend against them. We require user names and passwords as well as multi-factor authentication ("MFA") in order to access our information technology systems. These security measures are subject to potential third-party security breaches, employee error, malfeasance and faulty password management, among other limitations. Third parties may attempt to fraudulently induce employees or customers into disclosing user names, passwords or other sensitive information, which may in turn be used to access our information technology systems. We may not be able to anticipate, detect or recognize threats to our system or to implement effective preventive measures against all security breaches. If we were to experience a breach of our systems and were unable to protect sensitive data, such a breach could, among other things:

•risk exposing our confidential manufacturing processes and other trade secreted information that may lead to new and increased entrants and competitors in our business or cause other damage to the business;

•expose our customers' facilities and projects to increased safety and security risk;

•materially damage business partner and customer relationships;

•impact our reputation in the markets in which we compete for business;

•adversely impact our financial results and expose us to potential risk of loss or litigation; and/or

•require us to incur substantial costs or require us to change our business practices.

A material disruption at any of our manufacturing facilities could adversely affect our financial performance and results of operations.

If operations at any of our manufacturing facilities were to be disrupted as a result of significant equipment failures, natural disasters, pandemics, power outages, fires, explosions, terrorism, adverse weather conditions, labor disputes or other reasons, we may be unable to fill customer orders and meet customer demand for our products, which could adversely affect our financial performance and results of operations. For example, our marketing and research & development buildings, located on the same campus as our former corporate headquarters and primary manufacturing facility in San Marcos, Texas, were destroyed by a tornado in January 2007. In addition, precautionary measures instituted by government authorities in certain markets and sanitization procedures adopted to protect our employees in response to the COVID-19 pandemic have required us to temporarily suspend operations at certain of our manufacturing facilities.

    Interruptions in production, in particular at our manufacturing facilities in the United States or Canada, at which we manufacture the majority of our products, could increase our costs and reduce our sales. Any interruption in production capability could require us to make substantial capital expenditures to fill customer orders, which could negatively affect our profitability and financial condition. We maintain property damage insurance that we believe to be adequate to provide for reconstruction of facilities and equipment, as well as business interruption insurance to mitigate losses resulting from any production interruption or shutdown caused by an insured loss. However, any recovery under our insurance policies may not offset the lost sales or increased costs that may be experienced during the disruption of operations, which could adversely affect our financial performance and results of operations.

Our dependence on subcontractors and third-party suppliers could adversely affect our results of operations.

We often rely on third-party subcontractors, suppliers and manufacturers to produce our products and complete our projects. To the extent we cannot engage subcontractors or acquire supplies or raw materials from third parties, our ability to produce our products or complete our projects in a timely fashion or at a profit may be impaired. If the amount we are required to pay for these goods and services exceeds the amount we have estimated in bidding for fixed-price contracts, we could experience losses on these contracts. In addition, if a subcontractor or supplier is unable to deliver its services or materials

16

according to the negotiated contract terms for any reason, including the deterioration of its financial condition or over-commitment of its resources, we may be required to purchase the services or materials from another source at a higher price or, if unavailable, limit the availability of products critical to our operations. Such shortages or disruptions could be caused by factors beyond the control of our subcontractors, our suppliers or us, including inclement weather, natural disasters, increased demand, problems in production or distribution, disruptions in third party logistics or transportation systems or the inability of our subcontractors or suppliers to obtain credit. This may reduce the profit we realize or result in a loss on a project for which the services or materials were needed or, if the product is unavailable, prevent us from accepting orders.

We may lose money on fixed-price contracts, and we are exposed to liquidated damages charges and warranty claims in many of our customer contracts.

We often agree to provide products and services under fixed-price contracts, including our turnkey solutions. Under these contracts, we are typically responsible for all cost overruns, other than the amount of any cost overruns resulting from requested changes in order specifications. Our actual costs and any gross profit realized on these fixed-price contracts could vary from the estimated costs on which these contracts were originally based. This may occur for various reasons, including errors in estimates or bidding, changes in availability and cost of labor and raw materials and unforeseen technical and logistical challenges, including with managing our geographically widespread operations and use of third party subcontractors, suppliers and manufacturers in many countries. These variations and the risks inherent in our projects may result in reduced profitability or losses on projects. Depending on the size of a project, variations from estimated contract performance could have a material adverse impact on our project revenue and operating results. In addition, many of our customer contracts, including fixed-price contracts, contain liquidated damages and warranty provisions for which we are responsible in the event that we fail to perform our obligations thereunder in a timely manner or our products or services fail to perform, in accordance with the agreed terms, conditions and standards.

We extend credit to customers in conjunction with our performance under fixed-price contracts which subjects us to potential credit risks.

We typically agree to allow our customers to defer payment on projects until certain milestones have been met or until the projects are substantially completed, and customers typically withhold some portion of amounts due to us as retainage. Our payment arrangements subject us to potential credit risk related to changes in business and economic factors affecting our customers, including material changes in our customers' revenues or cash flows. These credit risks may be exacerbated by the effects of the global pandemic. If we are unable to collect amounts owed to us, or retain amounts paid to us, our cash flows would be reduced, and we could experience losses if those amounts exceed current allowances. Any of these factors could adversely impact our business and results of operations.

We may not achieve some or all of the expected benefits of our operational initiatives.

In order to align our operational resources with our business strategies, operate more efficiently and control costs, we may periodically announce plans to restructure certain of our operations, such as consolidation of manufacturing facilities, transitions to cost-competitive regions and product line rationalizations. We may also undertake restructuring actions and workforce reductions. For example, during fiscal 2021, we enacted certain restructuring initiatives to align our current cost structure with the present decline in demand for our products and services primarily due to COVID-19 and supply/demand fluctuations in commodity prices. Refer to Item 8, Financial Statements and Supplementary Data for more discussion. Risks associated with these actions include delays in execution, additional unexpected costs, realization of fewer than estimated productivity improvements and adverse effects on employee morale. If these risks materialize, we may not realize all or any of the anticipated benefits of such restructuring plans, which could have a material adverse effect on our business, financial condition, results of operations and cash flows.

Unforeseen difficulties with expansions, relocations or consolidations of existing facilities could adversely affect our operations.

From time to time we may decide to enter new markets, build or lease additional facilities, expand our existing facilities, relocate or consolidate one or more of our operations or exit a facility we may own or lease. Increased costs and production delays arising from the staffing, relocation, sublease, expansion or consolidation of our facilities could adversely affect our business and results of operations.

Legal and Regulatory Risks

17

Due to the nature of our business, we may be liable for damages based on product liability claims. We are also exposed to potential indemnity claims from customers for losses due to our work or if our employees are injured performing services.

We face a risk of exposure to legal claims and costs of litigation in the event that the failure, use or misuse of our products results in, or is alleged to result in, death, bodily injury, property damage or economic loss. Although we maintain quality controls and procedures, we cannot be sure that our products will be free from defects. If any of our products prove to be defective, we may be required to replace the product. In addition, we may be required to recall or redesign such products, which could result in significant unexpected costs. Some of our products contain components manufactured by third parties, which may also have defects. In addition, if we are installing our products, we may be subject to claims that our installation has caused damage or loss. Our products are often installed in our customers' or end-users' complex and capital intensive facilities involved in inherently hazardous or dangerous industries, including energy, chemical processing and power generation, where the potential liability from risk of loss could be substantial. Although we currently maintain product liability coverage, which we believe is adequate for the continued operation of our business, we cannot be certain that this insurance coverage will continue to be available to us at a reasonable cost or, if available, will be adequate to cover any potential liabilities. With respect to components manufactured by third-party suppliers, the contractual indemnification that we seek from our third-party suppliers may be insufficient to cover claims made against us. In the event that we do not have adequate insurance or contractual indemnification, product liabilities and other claims could have a material adverse effect on our business, financial condition or results of operations.

Under our customer contracts, we often indemnify our customers from damages and losses they incur due to our work or services performed by us, as well as for losses our customers incur due to any injury or loss of life suffered by any of our employees or our subcontractors' personnel occurring on our customer's property. Substantial indemnity claims may exceed the amount of insurance we maintain and could have a material adverse effect on our reputation, business, financial condition or results of operations.

We operate in many different jurisdictions and we could be adversely affected by violations of the U.S. Foreign Corrupt Practices Act and similar foreign anti-corruption laws.

The U.S. Foreign Corrupt Practices Act (the “FCPA”) and similar foreign anti-corruption laws generally prohibit companies and their intermediaries from making improper payments or providing anything of value to influence foreign government officials for the purpose of obtaining or retaining business or obtaining an unfair advantage. Recent years have seen a substantial increase in the global enforcement of anti-corruption laws, with more frequent voluntary self-disclosures by companies, aggressive investigations and enforcement proceedings by both the DOJ and the SEC resulting in record fines and penalties, increased enforcement activity by non-U.S. regulators, and increases in criminal and civil proceedings brought against companies and individuals. Because many of our customers, sales channels and end-users are involved in infrastructure construction and energy production, they are often subject to increased scrutiny by regulators. Our internal policies mandate compliance with these anti-corruption laws. However, we operate in many parts of the world that are recognized as having governmental corruption problems to some degree and where strict compliance with anti-corruption laws may conflict with local customs and practices. Our continued operation and expansion outside the United States, including in developing countries, could increase the risk of such violations in the future. Despite our training and compliance programs, we cannot assure you that our internal control policies and procedures always will protect us from unauthorized reckless or criminal acts committed by our employees or agents. In the event that we believe or have reason to believe that our employees or agents have or may have violated applicable anti-corruption laws, including the FCPA, we may be required to investigate or have outside counsel investigate the relevant facts and circumstances, which can be expensive and require significant time and attention from senior management. Violations of these laws may result in severe criminal or civil sanctions, which could disrupt our business and result in adverse effects on our reputation, business, results of operations or financial condition.

Our international operations and non-U.S. subsidiaries are subject to a variety of complex and continually changing laws and regulations and, in particular, export control regulations or sanctions.

Due to the international scope of our operations, we are subject to a complex system of laws and regulations, including regulations issued by the U.S. Department of Justice (the “DOJ”), the SEC, the IRS, the U.S. Department of Treasury, the U.S. Department of State, Customs and Border Protection, Bureau of Industry and Security (“BIS”), Office of Anti-Boycott Compliance (“OAC”) and Office of Foreign Asset Control (“OFAC”), as well as the counterparts of these agencies in foreign countries. While we believe we are in material compliance with these regulations and maintain programs intended to achieve compliance, we may currently or may in the future be in violation of these regulations. In 2009, we entered into settlement agreements with BIS and OFAC, and in 2010, we entered into a settlement agreement with OAC, in each case with respect to matters we voluntarily disclosed to such agencies.

18

The Dodd-Frank Wall Street Reform and Consumer Protection Act (the "Dodd-Frank Act") requires various federal agencies to adopt a broad range of new implementing rules and regulations, and to prepare numerous studies and reports for Congress. Under the Dodd-Frank Act, the SEC has adopted requirements for companies that use certain minerals and metals, known as “conflict minerals”, in their products, whether or not these products are manufactured by third parties. These regulations require companies to perform due diligence, disclose and report whether or not such minerals originate from the Democratic Republic of Congo and adjoining countries. We are required to perform sufficient due diligence to determine whether such minerals are used in the manufacture of our products. The implementation of these requirements could adversely affect the sourcing, availability and pricing of such minerals if they are found to be used in the manufacture of our products. In addition, we incur costs to comply with conflict mineral disclosure requirements, including costs related to determining the source of any of the relevant minerals and metals used in our products. Since our supply chain is complex, we may not be able to sufficiently verify the origins for these minerals and metals used in our products through the due diligence procedures that we implement, which may harm our reputation. In such event, we may also face difficulties in satisfying customers who require that all of the components of our products are certified as conflict mineral free.

Any alleged or actual violations of these conflict mineral requirements may subject us to government scrutiny, investigation and civil and criminal penalties and may limit our ability to export our products or provide services outside the U.S. Additionally, we cannot predict the nature, scope or effect of future regulatory requirements to which our international operations might be subject or the manner in which existing laws might be administered or interpreted.

In addition, our geographically widespread operations, coupled with our relatively smaller offices in many countries and our reliance on third party subcontractors, suppliers and manufacturers in the completion of our projects, make it more difficult to oversee and ensure that all our offices and employees comply with our internal policies and control procedures. We have experienced immaterial employee theft in the past, and we cannot assure you that we can ensure our employees compliance with our internal control policies and procedures.

Changes in government administrative policy, including changes to existing trade agreements and government sanctions, could have a material adverse effect on us.

As a result of changes to government administrative policy, there may be changes to existing trade agreements, greater restrictions on free trade generally, significant increases in tariffs on goods imported into the U.S., Canada or the European Union, particularly tariffs on products manufactured in China and Mexico, among other possible changes. Changes in social, political, regulatory and economic conditions or in laws and policies governing foreign trade, manufacturing, development and investment in the territories and countries where we currently manufacture and sell products, and any resulting negative sentiments towards U.S. companies as a result of such changes, could have an adverse effect on our business, financial condition, results of operations and cash flows.

Currency fluctuations and the current geopolitical instability in Russia and Ukraine and related sanctions by the U.S. government against certain companies and individuals may hinder our ability to conduct business with potential or existing customers and vendors in these countries.

    We derived approximately 8%, 4% and 3% of our revenue from our subsidiary incorporated in Russia in the fiscal years ended March 31, 2021, 2020 and 2019, respectively. The escalation of geopolitical instability in Russia and Ukraine as well as currency fluctuations in the Russian Ruble could negatively impact our operations, sales, and future growth prospects in that region. The U.S. government has imposed sanctions through several executive orders restricting U.S. companies from conducting business with specified Russian and Ukrainian individuals and companies. While we believe that the executive orders currently do not preclude us from conducting business with our current customers or vendors in Russia, the sanctions imposed by the U.S. government may be expanded in the future to restrict us from engaging with them. If we are unable to conduct business with new or existing customers or vendors or pursue business opportunities in Russia or Ukraine, our business, including revenue, profitability and cash flows, and operations could be adversely affected. We cannot provide assurance that current sanctions or potential future changes in sanctions will not have a material impact on our operations in Russia and the Ukraine or on our financial results.

We are subject to numerous environmental and health and safety laws and regulations, as well as potential environmental liabilities, which may require us to make substantial expenditures.

Our operations and properties are subject to a variety of federal, state, local and foreign environmental laws and regulations, including those governing the discharge of pollutants into the air or water, the management and disposal of hazardous substances or wastes, the cleanup of contaminated sites and workplace health and safety. As an owner or operator of real property, or generator of waste, we could become subject to liability for environmental contamination, regardless of

19

whether we caused such contamination. Certain environmental laws, including the Comprehensive Environmental Response, Compensation, and Liability Act, impose joint and several liability for cleanup costs, without regard to fault, on persons who have disposed of or released hazardous substances into the environment. In addition, we could become liable to third parties for damages resulting from the disposal or release of hazardous substances into the environment. Some of our operations require environmental permits and controls to prevent and reduce air and water pollution, and these permits are subject to modification, renewal and revocation by issuing authorities. From time to time, we could be subject to requests for information, notices of violation, and/or investigations initiated by environmental regulatory agencies relating to our operations and properties. Violations of environmental and health and safety laws can result in substantial penalties, civil and criminal sanctions, permit revocations, and facility shutdowns. Environmental and health and safety laws may change rapidly and have tended to become more stringent over time. As a result, we could incur costs for past, present, or future failure to comply with all environmental and health and safety laws and regulations. In addition, we could become subject to potential regulations concerning the emission of greenhouse gases, and while the effect of such future regulations cannot be determined at this time, they could require us to incur substantial costs in order to achieve and maintain compliance. In the ordinary course of business, we may be held responsible for any environmental damages we may cause to our customers' premises.

The effects of climate change and any related regulation of greenhouse gases could have a negative impact on our business.

Governments around the world are increasingly focused on enacting laws and regulations regarding climate change and regulation of greenhouse gases. Lawmakers and regulators in the jurisdictions where we operate have proposed or enacted regulations requiring reporting of greenhouse gas emissions and the restriction thereof, including increased fuel efficiency standards, carbon taxes or cap and trade systems, restrictive permitting, and incentives for renewable energy. In addition, efforts have been made and continue to be made in the international community toward the adoption of international treaties or protocols that would address global climate change issues and impose reductions of hydrocarbon-based fuels, including plans developed in connection with the Paris climate conference in December 2015 and the Katowice climate conference in December 2018. Laws or regulations incentivizing or mandating the use of alternative energy sources such as wind power and solar energy have also been enacted in certain jurisdictions. Additionally, numerous large cities globally and several countries have adopted programs to mandate or incentivize the conversion from internal combustion engine powered vehicles to electric-powered vehicles and placed restrictions on non-public transportation. Such policies or other laws, regulations, treaties and international agreements related to greenhouse gases and climate change may negatively impact the price of oil relative to other energy sources, reduce demand for hydrocarbons, or otherwise unfavorably impact our customers in the oil and gas, power generation and petrochemical industries. To the extent our customers, particularly our energy and industrial customers, are subject to any of these or other similar proposed or newly enacted laws and regulations or impacted by the change in energy prices due to such laws and regulations, we are exposed to risks that the additional costs incurred by customers to comply with such laws and regulations or that the deterioration of customers’ financial results as a result of changing energy prices could impact our customers’ ability or desire to continue to operate at similar levels in certain jurisdictions as historically seen or as currently anticipated, which could negatively impact their demand for our products and services. These laws and regulations could also increase costs associated with our operations, including costs for raw materials and transportation. The ultimate impact of greenhouse gas emissions-related agreements, legislation and measures on our financial performance is highly uncertain because we are unable to predict with certainty, for a multitude of individual jurisdictions, the outcome of political decision-making processes and the variables and trade-offs that inevitably occur in connection with such processes.

    In addition to potential impacts on our business resulting from climate-change legislation or regulations, our business also could be negatively affected by climate-change related physical changes or changes in weather patterns. An increase in severe weather patterns could result in damages to or loss of our manufacturing facilities, impact our ability to conduct our operations and/or result in a disruption of our customers’ operations. In addition, volatility in weather patterns could exacerbate the cyclicality of demand for our heating products.

Risks Related to Ownership of Our Common Stock

Our quarterly operating results may vary significantly, which could negatively impact the price of our common stock.

    Our quarterly results of operations have fluctuated in the past and will continue to fluctuate in the future. You should not rely on the results of any past quarter or quarters as an indication of future performance in our business operations or the price of our common stock. Factors that might cause our operating results to vary from quarter to quarter include, but are not limited to:

•general economic conditions and cyclicality in the end markets we serve;

•the effects of the ongoing COVID-19 pandemic or other global pandemics or catastrophes;

•future growth of energy and chemical processing capital investments;

20

•a material disruption at any of our manufacturing facilities;

•delays in our customers' projects for which our products are a component;

•the timing of completion of large Greenfield projects;

•costs associated with regulatory compliance;

•competition from various other sources providing similar heat tracing products and services, or other alternative technologies, to customers; and

•the seasonality of demand for MRO/UE orders, which is typically highest during the second and third fiscal quarters.

    If our results of operations from quarter to quarter fail to meet the expectations of securities analysts and investors, the price of our common stock could be negatively impacted.

The market price of our common stock may fluctuate significantly, and this may make it difficult for holders to resell our common stock when they want or at prices that they find attractive.

    The price of our common stock on the NYSE constantly changes. We expect that the market price of our common stock will continue to fluctuate. The market price of our common stock may fluctuate as a result of a variety of factors, many of which are beyond our control. These factors include, but are not limited to:

•quarterly fluctuations in our operating results;

•changes in investors' and analysts' perception of the business risks and conditions of our business or our competitors;

•our ability to meet the earnings estimates and other performance expectations of financial analysts or investors;

•unfavorable commentary or downgrades of our stock by equity research analysts;

•the emergence of new sales channels in which we are unable to compete effectively;

•disruption to our operations;

•fluctuations in the stock prices of our peer companies or in stock markets in general; and

•general economic or political conditions, including the effects of the COVID-19 pandemic.

In addition, in recent years, global equity markets have experienced extreme price and volume fluctuations. This volatility has had a significant effect on the market price of securities issued by many companies for reasons often unrelated to their operating performance. These broad market fluctuations may adversely affect the market price of our common stock, regardless of our operating results and cash flows.

Anti-takeover provisions contained in our amended and restated certificate of incorporation and amended and restated bylaws could impair a takeover attempt that our stockholders may find beneficial.

Our second amended and restated certificate of incorporation, amended and restated bylaws and Delaware law contain provisions that could have the effect of rendering more difficult, or discouraging, an acquisition deemed undesirable by our board of directors. Our corporate governance documents include provisions:

•authorizing our board of directors, without further action by the stockholders, to issue blank check preferred stock;

•limiting the ability of our stockholders to call and bring business before special meetings and to take action by written consent in lieu of a meeting;

•requiring advance notice of stockholder proposals for business to be conducted at meetings of our stockholders and for nominations of candidates for election to our board of directors;

•authorizing our board of directors, without stockholder approval, to amend our amended and restated bylaws;

•limiting the determination of the number of directors on our board of directors and the filling of vacancies or newly created seats on our board of directors to our board of directors then in office; and

•subject to certain exceptions, limiting our ability to engage in certain business combinations with an "interested stockholder" for a three-year period following the time that the stockholder became an interested stockholder.

These provisions, alone or together, could delay hostile takeovers and changes in control of the Company or changes in our management.

Though we have opted out of the Delaware anti-takeover statute, our second amended and restated certificate of incorporation contains provisions that are similar to the Delaware anti-takeover statute, which may impair a takeover attempt that our stockholders may find beneficial. Any provision of our second amended and restated certificate of incorporation or amended and restated bylaws that has the effect of delaying or deterring a change in control could limit the opportunity for our stockholders to receive a premium for their shares of our common stock, and could also affect the price that some investors are willing to pay for our common stock.

21

We do not currently intend to pay dividends on our common stock and, consequently, your ability to achieve a return on your investment will depend on appreciation in the price of our common stock.

    We do not expect to pay dividends on our common stock. Any future dividend payments are within the discretion of our board of directors or a duly authorized committee of the board of directors and will depend on, among other things, our results of operations, working capital requirements, capital expenditure requirements, financial condition, level of indebtedness, contractual restrictions with respect to payment of dividends, business opportunities, anticipated cash needs, provisions of applicable law and other factors that our board of directors may deem relevant. In particular, our credit facility limits our ability to pay dividends from cash generated from operations. We may not generate sufficient cash from operations in the future to pay dividends on our common stock. See Item 5, "Market for Registrant's Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities-Dividend Policy."

Dividend Policy

Since the completion of the CHS Transactions on April 30, 2010, we have not declared or paid any cash dividends on our capital stock, and we do not currently intend to pay any cash dividends on our common stock. We currently intend to retain earnings to finance the growth and development of our business and for working capital and general corporate purposes. We also use our cash to make unscheduled principal repayments on our debt over and above the required amounts.

Any payment of dividends will be at the discretion of our board of directors and will depend upon our earnings, financial condition, capital requirements, level of indebtedness, contractual restrictions with respect to payment of dividends, restrictions imposed by applicable law and other factors. In particular, our credit facility limits our ability to pay dividends from cash generated from operations.

Overview

For a complete overview of our business, please refer to Item 1. "Business" disclosed within this document.

Revenue. Our revenues are derived from providing customers with a full suite of innovative and reliable process heating solutions, including electric and steam heat tracing, tubing bundles, control systems, design optimization, engineering services, installation services, portable power solutions and software. Additionally, THS offers a complementary suite of advanced heating and filtration solutions for industrial and hazardous area applications. Historically, our sales are primarily to industrial customers for petroleum and chemical plants, oil and gas production facilities and power generation facilities. While our petroleum customers represent an important portion of our business, we have been successful broadening our customer base by earning business from numerous other industries, including chemical processing, power generation, transportation, food and beverage, commercial, pharmaceutical, and mineral processing.

Demand for industrial heat tracing solutions falls into two categories: (i) new facility construction, which we refer to as Greenfield projects, and (ii) recurring maintenance, repair and operations and facility upgrades or expansions, which we refer to as MRO/UE. Greenfield construction projects often require comprehensive heat tracing solutions. We believe that Greenfield revenue consists of sales revenue by customer in excess of $1 million annually (excluding sales to resellers), and typically includes most orders for projects related to facilities that are new or that are built independent of existing facilities. We refer to sales revenue by customer of less than $1 million annually, which we believe are typically derived from MRO/UE, as MRO/UE revenue. Based on our experience, we believe that $1 million in annual sales is an appropriate threshold for distinguishing between Greenfield revenue and MRO/UE revenue. However, we often sell our products to intermediaries or subcontract our services; accordingly, we have limited visibility into how our products or services may ultimately be used and can provide no assurance that our categorization may accurately reflect the sources of such revenue. Furthermore, our customers do not typically enter into long-term forward maintenance contracts with us. In any given year, certain of our smaller Greenfield projects may generate less than $1 million in annual sales, and certain of our larger plant expansions or upgrades may generate in excess of $1 million in annual sales, though we believe that such exceptions are few in number and insignificant to interpreting our overall results of operations. THS has been excluded from the Greenfield and MRO/UE calculations. Most of THS's revenue would be classified as MRO/UE under these definitions.

We believe that our pipeline of planned projects, in addition to our backlog of signed purchase orders, provides us with visibility into our future revenue. Historically we have experienced few order cancellations, and the cancellations that have occurred in the past have not been material compared to our total contract volume or total backlog. The small number of order cancellations is attributable in part to the fact that a large portion of our solutions are ordered and installed toward the end of Greenfield project construction. Our backlog at March 31, 2021 was $114.2 million as compared to $105.4 million at March 31, 2020. The timing of recognition of revenue out of backlog is not always certain, as it is subject to a variety of factors that may cause delays, many of which are beyond our control (such as, customers' delivery schedules and levels of capital and maintenance expenditures). When delays occur, the recognition of revenue associated with the delayed project is likewise deferred.

Cost of sales. Our cost of sales includes primarily the cost of raw material items used in the manufacture of our products, cost of ancillary products that are sourced from external suppliers and construction labor cost. Additional costs of revenue include contract engineering cost directly associated to projects, direct labor cost, shipping and handling costs, and other costs associated with our manufacturing/fabrication operations. The other costs associated with our manufacturing/fabrication operations are primarily indirect production costs, including depreciation, indirect labor costs, and the costs of

25

manufacturing support functions such as logistics and quality assurance. Key raw material costs include polymers, copper, stainless steel, insulating material, and other miscellaneous parts related to products manufactured or assembled as part of our heat tracing solutions. Historically, our primary raw materials have been readily available from multiple suppliers and raw material costs have been stable, and we have been generally successful with passing along raw material cost increases to our customers. Therefore, increases in the cost of key raw materials of our products have not generally affected our gross margins. We cannot provide any assurance that we may be able to pass along such cost increases, including the potential impacts of tariffs, to our customers in the future, and if we are unable to do so, our results of operations may be adversely affected.

Operating expenses. Our marketing, general, administrative, and engineering expenses are primarily comprised of compensation and related costs for sales, marketing, pre-sales engineering and administrative personnel, as well as other sales related expenses and other costs related to research and development, insurance, professional fees, the global integrated business information system, provisions for bad debts and warranty expense.

Key drivers affecting our results of operations. Our results of operations and financial condition are affected by numerous factors, including those described above under Item 1A, "Risk Factors" and elsewhere in this annual report and those described below:

    Timing of Greenfield projects. Our results of operations in recent years have been impacted by the various construction phases of large Greenfield projects. On very large projects, we are typically designated as the heat tracing provider of choice by the project owner. We then engage with multiple contractors to address incorporating various heat tracing solutions throughout the overall project. Our largest Greenfield projects may generate revenue for more than one year. In the early stages of a Greenfield project, our revenues are typically realized from the provision of engineering services. In the middle stages, or the material requirements phase, we typically experience the greatest demand for our heat tracing cable, at which point our revenues tend to accelerate. Revenues tend to decrease gradually in the final stages of a project and are generally derived from installation services and demand for electrical panels and other miscellaneous electronic components used in the final installation of heat tracing cable, which we frequently outsource from third-party manufacturers. Therefore, we typically provide a mix of products and services during each phase of a Greenfield project, and our margins fluctuate accordingly.

    Cyclicality of end-users' markets. Demand for our products and services depends in large part upon the level of capital and maintenance expenditures of our customers and end-users, in particular those in the energy, chemical processing and power generation industries, and firms that design and construct facilities for these industries. These customers' expenditures historically have been cyclical in nature and vulnerable to economic downturns. Greenfield projects, and especially large Greenfield projects (i.e., new facility construction projects generating in excess of $5 million in annual sales), historically have been a substantial source of revenue growth, and Greenfield revenues tend to be more cyclical than MRO/UE revenues. A sustained decrease in capital and maintenance spending or in new facility construction by our customers could have a material adverse effect on the demand for our products and services and our business, financial condition and results of operations.

    Acquisition strategy. In recent years, we have begun executing on a strategy to grow the Company through the acquisition of businesses that are either in the heat tracing solutions industry or that provide complementary products and solutions for the markets and customers we serve. We actively pursue both organic and inorganic growth initiatives that serve to advance our corporate strategy.

    Impact of product mix. Typically, both Greenfield and MRO/UE customers require our products as well as our engineering and construction services. The level of service and construction needs will affect the profit margin for each type of revenue. We tend to experience lower margins from our design optimization, engineering, installation and maintenance services than we do from sales of our heating units, heating cable, tubing bundle and control system products. We also tend to experience lower margins from our outsourced products, such as electrical switch gears and transformers, than we do from our manufactured products. Accordingly, our results of operations are impacted by our mix of products and services.

We estimate that Greenfield and MRO/UE have each made the following contribution as a percentage of revenue in the periods listed:

26

Fiscal Year Ended March 31,*
	2021		2020		2019
Greenfield	35	%	40	%	49	%
MRO/UE	65	%	60	%	51	%

*THS has been excluded from the table above. Most of THS's revenue would be classified as MRO/UE under the current definitions.

Greenfield revenue is an indicator of both our ability to successfully compete for new contracts as well as the economic health of the industries we serve. Furthermore, Greenfield revenue is an indicator of potential MRO/UE revenue in future years.

For MRO/UE orders, the sale of our manufactured products typically represents a higher proportion of the overall revenue associated with such order than the provision of our services. Greenfield projects, on the other hand, require a higher level of our services than MRO/UE orders, and often require us to purchase materials from third party vendors. Therefore, we typically realize higher margins from MRO/UE revenues than Greenfield revenues.

    Large and growing installed base. Customers typically use the incumbent heat tracing provider for MRO/UE projects to avoid complications and compatibility problems associated with switching providers. Therefore, with the significant Greenfield activity we have experienced in recent years, our installed base has continued to grow, and we expect that such installed base will continue to generate ongoing high margin MRO/UE revenue. For fiscal 2021, MRO/UE sales comprised approximately 65% of our consolidated revenues (excluding THS).

    Seasonality of MRO/UE revenues. MRO/UE revenues for the heat tracing business are typically highest during the second and third fiscal quarters, as most of our customers perform preventative maintenance prior to the winter season. However, revenues from Greenfield projects are not seasonal and depend on the capital spending environment and project timing.

Recent Developments - COVID-19 Pandemic. The recent COVID-19 pandemic and the measures being taken to address and limit the spread of the virus have adversely affected the economies and financial markets of many countries, resulting in an economic downturn that has negatively impacted, and may continue to negatively impact, global demand for our products and services. See part Item 1A, "Risk Factors" above, for further discussion. The Company has taken the following precautionary measures in light of current macroeconomic uncertainty resulting from the COVID-19 pandemic:

•Reduced discretionary spending across the organization by approximately $6.3 million in the fiscal year ending March 31, 2021 by curtailing consulting fees and travel expenses and consolidating our global operating footprint;

•Decreased payroll expense, including temporarily decreasing salaries for certain officers and implementing a reduction in force initiative that reduced ongoing personnel cost by approximately $15.9 million in the fiscal year ending March 31, 2021;

•Reduced capital expenditures in the fiscal year ending March 31, 2021 to approximately $8.1 million, which includes approximately $1.0 million year over year increase in strategic spending on our Thermon Power Solutions (“TPS”) product line (based on market demand), a reduction of approximately $2.8 million as compared to fiscal 2020; and

•Reduced manufacturing expense across the organization by approximately $1.8 million in the fiscal year ending March 31, 2021 by consolidating our manufacturing footprint.

"Related Party Transactions" to our consolidated financial statements included in Item 8 of this annual report for further discussion.

Year Ended March 31, 2021 ("fiscal 2021") Compared to the Year Ended March 31, 2020 ("fiscal 2020")

Revenue. Revenue for fiscal 2021 was $276.2 million, compared to $383.5 million for fiscal 2020, a decrease of $107.3 million, or 28%. Our sales mix (excluding THS) in fiscal 2021 was 35% Greenfield and 65% MRO/UE, as compared to 40% Greenfield and 60% MRO/UE in fiscal 2020. Greenfield revenue is historically at or near 40% of our total revenue.

In fiscal 2021 as compared to fiscal 2020, US-LAM reportable segment revenue decreased $60.0 million or 38.6%, Canada revenue decreased $37.5 million or 29.2%, APAC revenue decreased $10.2 million or 22.2%, and EMEA revenue increased $0.5 million or 0.9%. The decreases in our US-LAM, Canada, and APAC segments were primarily related to a decline in demand for our products and services in both Greenfield and MRO/UE business activity as a result of the COVID-19 driven economic downturn. Decreases in EMEA's segment revenue related to the COVID-19 driven economic downturn were more than offset by an increase in over time, project-related revenue within the region.

Gross profit and margin. Gross profit totaled $117.2 million in fiscal 2021, compared to $161.6 million in fiscal 2020, a decrease of $44.4 million, or 27%. Gross margins were 42.5% and 42.1% in fiscal 2021 and fiscal 2020, respectively. The lower gross profit in fiscal 2021 is primarily attributable to lower overall sales in connection with the depressed market conditions due to COVID-19. Although lower sales produced a lower gross profit in fiscal 2021, our margin percentage increased due to a greater mix of MRO/UE business relative to Greenfield plus overall cost reduction efforts described above and operational efficiencies in fiscal 2021. Additionally, the Canadian Emergency Wage Subsidy, through which we received subsidies with respect to our Canadian manufacturing operations, positively impacted our margins by $4.7 million in fiscal 2021. Please see Note 1, “Basis of Presentation and Accounting Policy Information” in our financial statements for more information on the Canadian Emergency Wage Subsidy.

Marketing, general, administrative, and engineering. Marketing, general, administrative and engineering costs were $91.4 million in fiscal 2021, compared to $111.2 million in fiscal 2020, a decrease of $19.8 million, or 17.8%. As a percentage

28

of total revenue, marketing, general, administrative, and engineering costs were 33.1% and 29.0% in fiscal 2021 and fiscal 2020, respectively. The decrease in fiscal 2021 marketing, general, administrative, and engineering costs is attributable to intentional decreases in response to the COVID-19 pandemic. Specifically, we undertook a reduction in force initiative to reduce costs throughout fiscal 2021. At this time, we believe we are substantially complete with the reduction in force cost measures. In addition, our Marketing, general, administrative and engineering costs were positively impacted by the Canadian Emergency Wage Subsidy in the amount of $2.2 million, through which we received government subsidies with respect to our Canadian manufacturing operations. These favorable costs reductions were partly offset by $0.7 million related to a specific customer past due account and an increase in compensation costs associated with the Company’s non-qualified deferred compensation plan. To note, these specific compensation plan costs are fully offset in other income/(expense) where the Company experienced market gains of $1.6 million on the related investment assets.

Amortization of intangible assets. Amortization of intangible assets was $9.4 million in fiscal 2021 and $17.8 million in fiscal 2020. The decrease in amortization expense is attributable to certain intangible assets that became fully amortized during fiscal 2020.

Restructuring and other charges/(income). Restructuring and other charges/(income) was $8.6 million in fiscal 2021. Refer to Note 14. "Restructuring and other charges/(income)" for further discussion. These charges were not present in the prior fiscal year.

Interest expense, net. Interest expense, net totaled $10.2 million in fiscal 2021, compared to $14.0 million in fiscal 2020, a decrease of $3.8 million. The decrease in interest expense is due to substantial principal prepayments during fiscal 2021 on both the revolving credit facility and the term loan B credit facility (see Note 11, "Long-Term Debt," to our consolidated financial statements included below in Item 8 of this annual report for further discussion). We paid a total of $25 million of principal above and in advance of our contractual obligation.

Other income/(expense). Other income was $2.1 million in fiscal 2021, compared to other expense of $1.6 million in fiscal 2020, a comparative decrease of expense of $3.7 million. The decrease in other expense primarily relates to transactional foreign exchange gains as well as market-related gains on underlying investments associated with our deferred compensation plan for certain high-level employees. The gains were partially offset by related compensation expense, included in Marketing, general, administrative and engineering costs as discussed above.

Income taxes. Income tax (benefit) was $(1.4) million in fiscal 2021, on pre-tax net loss of $(0.3) million compared to income tax expense of $5.1 million in fiscal 2020 on pre-tax net income of $17.1 million, a decrease of $6.5 million. The income tax (benefit) in the current period was primarily due to a pre-tax loss and the impact from the U.S. (global intangible low-taxed income) or "GILTI Tax". During fiscal 2021, tax law changes provided a $1.9 million recovery of previously incurred GILTI Tax expense.

See Note 18, “Income Taxes,” to our audited consolidated financial statements included elsewhere in this annual report, for further detail on income taxes.

Net income/(loss) available to Thermon Group Holdings, Inc. Net income available to the Company, after non-controlling interest, was $1.2 million in fiscal 2021 as compared to income of $11.9 million in fiscal 2020, a decrease of $10.7 million or 89.9%. The decrease in fiscal 2021 net income is primarily due to lower revenue, lower gross profit as a result, and restructuring and other charges/(income), as described above.

Year Ended March 31, 2020 ("fiscal 2020") Compared to the Year Ended March 31, 2019 ("fiscal 2019")

See Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our Annual Report on Form 10-K for the fiscal year ended March 31, 2020 filed with the SEC on June 1, 2020 for a discussion of the results of operations in fiscal 2020 as compared to fiscal 2019.

Contingencies

We are involved in various legal and administrative proceedings that arise from time to time in the ordinary course of doing business. Some of these proceedings may result in fines, penalties or judgments being assessed against us, which may adversely affect our financial results. In addition, from time to time, we are involved in various disputes, which may or may not be settled prior to legal proceedings being instituted and which may result in losses in excess of accrued liabilities, if any, relating to such unresolved disputes. As of March 31, 2021, management believes that adequate reserves have been established for any probable and reasonably estimable losses. Expenses related to litigation reduce operating income. We do not believe

29

that the outcome of any of these proceedings or disputes would have a significant adverse effect on our financial position, long-term results of operations, or cash flows. It is possible, however, that charges related to these matters could be significant to our results of operations or cash flows in any one accounting period. 

    For information on legal proceedings, see Note 15, "Commitments and Contingencies" to our consolidated financial

statements contained elsewhere in this annual report, which is hereby incorporated by reference into this Item 7.

    To bid on or secure certain contracts, we are required at times to provide a performance guaranty to our customers in the form of a surety bond, standby letter of credit or foreign bank guaranty. On March 31, 2021, we had in place standby letters of credit, bank guarantees and performance bonds totaling $10.0 million to back our various customer contracts. Our Indian subsidiary also has $4.9 million in customs bonds outstanding.

Liquidity and Capital Resources

Our primary sources of liquidity are cash flows from operations and funds available under our revolving credit facility and other revolving lines of credit. Our primary liquidity needs are to finance our working capital, capital expenditures, debt service needs and potential future acquisitions. In October 2017, we entered into a new credit agreement that provides for (i) a seven-year $250.0 million variable rate senior secured term loan B facility and (ii) a five-year $60.0 million senior secured revolving credit facility. At March 31, 2021, outstanding principal under the term loan B facility was $148.5 million and we had no outstanding borrowings under our revolving credit facility.

Cash and cash equivalents. At March 31, 2021, we had $40.1 million in cash and cash equivalents. We maintain cash and cash equivalents at various financial institutions located in many countries throughout the world. Approximately $10.0 million, or 25%, of these amounts were held in domestic accounts with various institutions and approximately $30.1 million, or 75%, of these amounts were held in accounts outside of the United States with various financial institutions.

Senior secured credit facility. See Note 11, “Long-Term Debt—Senior Secured Credit Facility” to our consolidated financial statements and accompanying notes thereto included in Item 8 of this annual report for additional information on our senior secured term loan and revolving credit facilities, which is hereby incorporated by reference into this Item 7 . At March 31, 2021, we had no outstanding borrowings under our revolving credit facility and $56.7 million of available capacity thereunder, after taking into account the borrowing base and letters of credit outstanding, which totaled $3.3 million. From time to time, we may choose to utilize our revolving credit facility to fund operations, acquisitions or other investments, despite having cash available within our consolidated group in light of the cost, timing and other business considerations.

As of March 31, 2021, we had $148.5 million of outstanding principal on our term loan B facility. We are required to make quarterly principal payments of the term loan of $0.6 million through July 31, 2024. Thereafter, the remaining principal balance will be settled with a lump-sum payment of $139.8 million due at maturity of the term loan in October 2024. During the fiscal year ended March 31, 2021, we made voluntary debt prepayments of principal on the term loan B facility of $25.0 million. From time to time, we may choose to make unscheduled and additional prepayments of principal on the term loan B based on available cash flows.

    Guarantees; security. The term loan is guaranteed by the Company and all of the Company's current and future wholly owned domestic material subsidiaries (the “U.S. Subsidiary Guarantors”), subject to certain exceptions. Obligations of the Company under the revolving credit facility are guaranteed by the Company and the U.S. Subsidiary Guarantors. The obligations of Thermon Canada Inc. (the “Canadian Borrower”) under the revolving credit facility are guaranteed by the Company, Thermon Holding Corp. (the “U.S. Borrower”), the U.S. Subsidiary Guarantors and each of the wholly owned Canadian material subsidiaries of the Canadian Borrower, subject to certain exceptions. The term loan and the obligations of the U.S. Borrower under the revolving credit facility are secured by a first lien on all of the Company’s assets and the assets of the U.S. Subsidiary Guarantors, including 100% of the capital stock of the U.S. Subsidiary Guarantors and 65% of the capital stock of the first tier material foreign subsidiaries of the Company, the U.S. Borrower and the U.S. Subsidiary Guarantors, subject to certain exceptions. The obligations of the Canadian Borrower under the revolving credit facility are secured by a first lien on all of the Company's assets, the U.S. Subsidiary Guarantors' assets, the Canadian Borrower’s assets and the assets of the material Canadian subsidiaries of the Canadian Borrower, including 100% of the capital stock of the Canadian Borrower’s material Canadian subsidiaries.

    Financial covenants.  The term loan is not subject to any financial covenants. The revolving credit facility requires the Company, on a consolidated basis, to maintain certain financial covenant ratios. The Company must maintain a consolidated leverage ratio of 3.75:1.0 as measured on the last day of any fiscal quarter. In addition, on the last day of any period of four fiscal quarters, the Company must maintain a consolidated fixed charge coverage ratio of not less than 1.25:1.0. As of March 31, 2021, we were in compliance with all financial covenants of the credit facility.

30

    Restrictive covenants. The credit agreement governing our credit facility contains various restrictive covenants that, among other things, restrict or limit our ability to (subject to certain negotiated exceptions): incur additional indebtedness; grant liens; make fundamental changes; sell assets; make restricted payments including cash dividends to shareholders; enter into sales and leaseback transactions; make investments; prepay certain indebtedness; enter into certain transactions with affiliates; and enter into restrictive agreements.

    Repatriation considerations. Given the significant changes and potential opportunities under the U.S. Tax Cuts and Jobs Act of 2017 (the “Tax Act”) to repatriate cash tax free, we have reevaluated our current indefinite assertions. Beginning with fiscal 2018, we no longer assert a permanent reinvestment position in most of our foreign subsidiaries. We expect to repatriate certain earnings which will be subject to withholding taxes. These additional withholding taxes are being recorded as an additional deferred tax liability associated with the basis difference in such jurisdictions. Any changes made by foreign jurisdictions to their respective withholding rates could impact future tax expense and cash flow.

    Future capital requirements. Our future capital requirements will depend on a number of factors. We believe that, based on our current level of operations, cash flow from operations and available cash, together with available borrowings under our revolving credit facility, will be adequate to meet our liquidity needs for the next 12 months. We cannot assure you that our business will generate sufficient cash flow from operations or that future borrowings will be available to us in an amount sufficient to enable us to service our indebtedness, including our credit facility borrowings, or to fund our other liquidity needs. In addition, upon the occurrence of certain events, such as a change of control, we could be required to repay or refinance our indebtedness. We cannot assure you that we will be able to refinance any of our indebtedness, including our credit facility, on commercially reasonable terms or at all.

In fiscal 2021, we invested $8.1 million in capital expenditures. TPS purchased $4.6 million in property, plant and equipment, primarily related to leased equipment. We invested $3.1 million in our US-LAM segment primarily related to building improvements, leased equipment, and further investments in technology, furniture and fixture replacements, and capital maintenance.

Year Ended March 31, 2021 ("fiscal 2021") Compared to the Year Ended March 31, 2020 ("fiscal 2020")

Net cash provided by operating activities totaled $30.3 million for fiscal 2021 compared to $70.7 million for fiscal 2020, a decrease of $40.4 million. The decrease was primarily attributable to a $19.7 million decrease in cash provided by working capital accounts, a decrease of $10.8 million in net income, and $9.9 million decrease in cash provided from non-cash reconciling items.

    Our working capital assets in accounts receivable, inventory, contract assets, and other current assets represented a source of cash of $17.6 million and $20.2 million in fiscal 2021 and fiscal 2020 respectively, a decrease in the source of cash of $2.6 million in fiscal 2021. During fiscal 2021, as compared to fiscal 2020 accounts receivable decreased on lower sales volume, representing a source of cash of $22.9 million and a source of cash of $9.4 million, respectively. Contract assets represented a use of cash of $2.7 million and a source of cash of $12.2 million in fiscal 2021 and fiscal 2020, respectively, which is primarily attributed to timing of billings on our projects. In fiscal 2021, our inventory balance increased slightly as compared to fiscal 2020 due to lower inventory turnover, representing a use of cash of $0.5 million for fiscal 2021 and a source of cash of $1.4 million in fiscal 2020.

Our combined balance of accounts payable, accrued liabilities and other non-current liabilities represented a use of cash of $6.3 million and source of cash of $3.1 million in fiscal 2021 and fiscal 2020, respectively, a total decrease of $9.4 million. The increase in the use of cash in fiscal 2021 is primarily due to decreased overall activity as well as the timing of vendor payments. Changes in our income taxes payable and receivable balances represented a use of cash of $6.8 million in fiscal 2021 and a source of cash of $0.9 million in fiscal 2020.

Net cash used in investing activities totaled $7.8 million for fiscal 2021 compared to $10.0 million for fiscal 2020, a decrease of $2.2 million in the use of cash. Net cash used in investing activities relates to the purchase of capital assets primarily to maintain the existing operations of the business; it also includes purchases and sales of equipment in our rental business. Capital expenditures in fiscal 2021 were curtailed due to our response to the economic downturn associated with the COVID-19 pandemic.

Net cash used in financing activities totaled $28.2 million in fiscal 2021, compared to $46.5 million for fiscal 2020, a comparative decrease of $18.3 million cash used in financing activities which is primarily attributable to increased principal prepayments on our credit facilities during fiscal 2020 as compared to fiscal 2021. Cash proceeds in financing activities are

31

primarily short-term borrowings, and cash used in financing activities are from contractual and voluntary principal payments on our outstanding long-term debt.

Year Ended March 31, 2020 ("fiscal 2020") Compared to the Year Ended March 31, 2019 ("fiscal 2019")

See Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our Annual Report on Form 10-K for the fiscal year ended March 31, 2020 filed with the SEC on June 1, 2020 for a discussion of net cash provided by operating activities, net cash used in investing activities and net cash provided by (used in) financing activities in fiscal 2020 as compared to fiscal 2019.

Off-Balance Sheet Arrangements

We do not have any off balance sheet arrangements. In addition, we do not have any interest in entities referred to as variable interest entities, which include special purpose entities and other structured finance entities.

Effect of Inflation

While inflationary increases in certain input costs, such as wages, have an impact on our operating results, inflation has had minimal net impact on our operating results during the last three years, as overall inflation has been offset by lower commodity prices for our core production materials. We cannot assure you, however, that we will not be affected by general inflation in the future.

Seasonality

Demand for our products depends in large part upon the level of capital and maintenance expenditures by many of our customers and end-users, in particular those customers in the oil and gas, refining, chemical processing and transportation markets. These customers' expenditures historically have been cyclical in nature and vulnerable to economic downturns. In addition, quarterly revenues for the heat tracing business are impacted by the level and timing of large Greenfield projects that may be occurring at any given time. Our operating expenses remain relatively consistent with some variability related to overall headcount of the Company.

Our quarterly operating results may fluctuate based on the cyclical pattern of industries to which we provide heat tracing solutions and the seasonality of MRO/UE demand for our heat tracing products. Most of our heat tracing customers perform preventative maintenance prior to the winter season, typically making our second and third fiscal quarters the largest for MRO/UE revenue. However, revenues from Greenfield projects are not seasonal and depend on the capital spending environment and project timing.

THS typically experiences more pronounced seasonality than our legacy heat tracing business, with a noticeable increase in revenue and profitability typically beginning in the third fiscal quarter and continuing during the winter months through the end of the fourth fiscal quarter.

Critical Accounting Policies and Estimates

The preparation of our financial statements in accordance with GAAP requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, expenses and related disclosures of contingent assets and liabilities. We base our estimates on past experience and other assumptions that we believe are reasonable under the circumstances, and we evaluate these estimates on an ongoing basis. Our critical accounting policies are those that materially affect our financial statements and involve difficult, subjective or complex judgments by management. Our most significant financial statement estimates include revenue recognition, estimating allowances, specifically the allowance for doubtful accounts and the adjustment for excess and obsolete inventories, valuation of long-lived assets, goodwill, and other intangible assets, accounting for income taxes, loss contingencies, and stock-based compensation expense.

Although these estimates are based on management's best knowledge of current events and actions that may impact the company in the future, actual results may be materially different from the estimates.

Revenue recognition. Please refer to Note 4 "Revenue from Contracts with Customers" of our consolidated financial statements included below in Item 8 of this annual report for further discussion, including the impact the adoption had on our consolidated financial statements.

Estimating allowances, specifically the allowance for doubtful accounts and the adjustment for excess and obsolete inventories. The Company's receivables are recorded at cost when earned and represent claims against third parties that will be settled in cash. The carrying value of the Company's receivables, net of allowance for doubtful accounts, represents their estimated net realizable value. If events or changes in circumstances indicate specific receivable balances may be impaired, further consideration is given to the Company's ability to collect those balances and the allowance is adjusted accordingly. The Company has established an allowance for doubtful accounts based upon an analysis of aged receivables. Past-due receivable balances are written-off when the Company's internal collection efforts have been unsuccessful in collecting the amounts due.

The major end markets that drive demand for process heating include chemical and petrochemical, up-, mid- and downstream oil and gas, power generation, commercial, and rail and transit. From time to time, the Company has experienced significant credit losses with respect to individual customers; however, historically, these credit losses have been isolated to specific customers rather than across an industry and have been infrequent. The Company's foreign receivables are not concentrated within any one geographic segment nor are they subject to any current economic conditions that would subject the Company to unusual risk. The Company does not generally require collateral or other security from customers.

We perform credit evaluations of new customers and sometimes require deposits, prepayments or use of trade letters of credit to mitigate our credit risk. Allowance for doubtful account balances were $2.1 million and $0.8 million as of March 31, 2021 and 2020, respectively. Although we have fully provided for these balances, we continue to pursue collection of these receivables.

We write down our inventory for estimated excess or obsolete inventory equal to the difference between the cost of inventory and estimated net realizable value based on assumptions of future demand and market conditions. Net realizable value is determined quarterly by comparing inventory levels of individual products and components to historical usage rates, current backlog and estimated future sales and by analyzing the age and potential applications of inventory, in order to identify specific products and components of inventory that are judged unlikely to be sold. Our finished goods inventory consists primarily of completed electrical cable that has been manufactured for various heat tracing solutions. Most of our manufactured product offerings are built to industry standard specifications that have general purpose applications and therefore are sold to a variety of customers in various industries. Some of our products, such as custom orders and ancillary components outsourced from third-party manufacturers, have more specific applications and therefore may be at a higher risk of inventory obsolescence. Inventory is written-off in the period in which the disposal occurs. Actual future write-offs of inventory for salability and obsolescence reasons may differ from estimates and calculations used to determine valuation allowances due to changes in customer demand, customer negotiations, product application, technology shifts and other factors. Our allowance for excess and obsolete inventories was $1.8 million and $2.0 million at March 31, 2021 and 2020, respectively. Historically, inventory obsolescence and potential excess cost adjustments have been within our expectations, and management does not believe that there is a reasonable likelihood that there will be a material change in future estimates or assumptions used to calculate the inventory valuation reserves.

Significant judgments and estimates must be made and used in connection with establishing these allowances. If our assumptions used to calculate these allowances do not agree with our future ability to collect outstanding receivables, or the actual demand for our inventory, additional provisions may be needed and our future results of operations could be adversely affected.

Valuation of long-lived, goodwill and other intangible assets. We conduct a required annual review of goodwill for potential impairment in the fourth quarter, or sooner if events or changes in circumstances indicate that the fair value of a reporting unit is below its carrying value. Our reporting units are our operating segments: US-LAM, Canada, EMEA, and APAC. We have the option to perform a qualitative assessment to satisfy the annual test requirement if we believe that it is more likely than not that we do not have an impairment in any one of our reporting units. If the carrying value of a reporting unit that includes goodwill exceeds its fair value, which is determined using both the income approach and market approach, goodwill is considered impaired. The income approach determines fair value based on discounted cash flow model derived from a reporting unit’s long-term forecasted cash flows. The market approach determines fair value based on the application of earnings multiples of comparable companies to projected earnings of the reporting unit. The amount of impairment loss is measured as the difference between the carrying value and the fair value of a reporting unit but is limited to the total amount of goodwill allocated to the reporting unit. In performing the fair value analysis, management makes various judgments, estimates and assumptions, the most significant of which is the assumption related to revenue growth rates.

The factors we considered in developing our estimates and projections for cash flows include, but are not limited to, the following: (i) macroeconomic conditions; (ii) industry and market considerations; (iii) costs, such as increases in raw materials, labor, or other costs; (iv) our overall financial performance; and, (v) other relevant entity-specific events that impact our reporting units. The determination of whether goodwill is impaired involves a significant level of judgment in the

33

assumptions underlying the approach used to determine the estimated fair values of our reporting units. We believe that the estimates and assumptions used in our impairment assessment are reasonable; however, these assumptions are judgmental and variations in any assumptions could result in materially different calculations of fair value. We will continue to evaluate goodwill on an annual basis in our fourth quarter, and whenever events or changes in circumstances, such as significant adverse changes in operating results, market conditions, or changes in management’s business strategy indicate that there may be a probable indicator of impairment. It is possible that the assumptions used by management related to the evaluation may change or that actual results may vary significantly from management’s estimates. In fiscal 2021, 2020 and 2019, the Company determined that no impairment of goodwill existed.

Other intangible assets include indefinite lived intangible assets for which we must also perform an annual test of impairment. The Company's indefinite lived intangible assets consist primarily of trademarks. The fair value of the Company's trademarks is calculated using a "relief from royalty payments" methodology. This approach involves first estimating reasonable royalty rates for each trademark then applying these royalty rates to a net sales stream and discounting the resulting cash flows to determine the fair value. The royalty rate is estimated using both a market and income approach. The market approach relies on the existence of identifiable transactions in the marketplace involving the licensing of trademarks similar to those owned by the Company. The income approach uses a projected pretax profitability rate relevant to the licensed income stream. We believe the use of multiple valuation techniques results in a more accurate indicator of the fair value of each trademark. This fair value is then compared with the carrying value of each trademark. The results of this test during the fourth quarter of our fiscal year indicated that there was no impairment of our indefinite life intangible assets during fiscal 2021, 2020 and 2019.

Accounting for income taxes. We account for income taxes under the asset and liability method that requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been recognized in our financial statements or tax returns. Judgment is required in assessing the future tax consequences of events that have been recognized in our financial statements or tax returns. Variations in the actual outcome of these future tax consequences could materially impact our financial position, results of operations or effective tax rate.

Significant judgment is required in determining our worldwide income tax provision. In the ordinary course of a global business, there are many transactions and calculations where the ultimate tax outcome is uncertain. Some of these uncertainties arise as a consequence of revenue sharing and cost reimbursement arrangements among related entities, the process of identifying items of revenue and expense that qualify for preferential tax treatment, and segregation of foreign and domestic earnings and expenses to avoid double taxation. Although we believe that our estimates are reasonable, the final tax outcome of these matters could be different from that which is reflected in our historical income tax provisions and accruals. Such differences could have a material effect on our income tax provision and net income in the period in which such determination is made.

In estimating future tax consequences, all expected future events are considered other than enactments of changes in tax laws or rates. Valuation allowances are established when necessary to reduce deferred tax assets to amounts which are more likely than not to be realized. We consider future growth, forecasted earnings, future taxable income, the mix of earnings in the jurisdictions in which we operate, historical earnings, taxable income in prior years, if carryback is permitted under the law, and prudent and feasible tax planning strategies in determining the need for a valuation allowance. In the event we were to determine that we would not be able to realize all or part of our net deferred tax assets in the future, an adjustment to the deferred tax assets valuation allowance would be charged to earnings in the period in which we make such a determination, or goodwill would be adjusted at our final determination of the valuation allowance related to an acquisition within the measurement period. If we later determine that it is more likely than not that the net deferred tax assets would be realized, we would reverse the applicable portion of the previously provided valuation allowance as an adjustment to earnings at such time. The amount of income tax we pay is subject to ongoing audits by federal, state and foreign tax authorities, which often result in proposed assessments. Our estimate of the potential outcome for any uncertain tax issue is highly judgmental. We account for these uncertain tax issues pursuant to ASC 740, Income Taxes, which contains a two-step approach to recognizing and measuring uncertain tax positions taken or expected to be taken in a tax return. The first step is to determine if the weight of available evidence indicates that it is more likely than not that the tax position will be sustained on audit, including resolution of any related appeals or litigation processes. The second step is to measure the tax benefit as the largest amount that is more than 50% likely to be realized upon ultimate settlement. Although we believe we have adequately reserved for our uncertain tax positions, no assurance can be given with respect to the final outcome of these matters. We adjust reserves for our uncertain tax positions due to changing facts and circumstances, such as the closing of a tax audit, judicial rulings, refinement of estimates or realization of earnings or deductions that differ from our estimates. To the extent that the final outcome of these matters is different than the amounts recorded, such differences generally will impact our provision for income taxes in the period in which such a determination is made. Our provisions for income taxes include the impact of reserve provisions and changes to reserves that are considered appropriate and also include the related interest and penalties.

34

We expect to repatriate certain foreign earnings from jurisdictions that are subject to withholding taxes. These additional withholding taxes are being recorded as an additional deferred tax liability associated with the basis difference in such jurisdictions.

Loss contingencies. We accrue for probable losses from contingencies including legal defense costs, on an undiscounted basis, when such costs are considered probable of being incurred and are reasonably estimable. We periodically evaluate available information, both internal and external, relative to such contingencies and adjust this accrual as necessary. Disclosure of a contingency is required if there is at least a reasonable possibility that a loss has been incurred. In determining whether a loss should be accrued we evaluate, among other factors, the degree of probability of an unfavorable outcome and the ability to make a reasonable estimate of the amount of loss.

Stock-based compensation expense. We account for share-based payments to employees in accordance with ASC 718, Compensation-Stock Compensation, which requires that share-based payments (to the extent they are compensatory) be recognized in our consolidated statements of operations and comprehensive income/(loss) based on their fair values.

As required by ASC 718, we recognize stock-based compensation expense for share-based payments that are expected to vest. In determining whether an award is expected to vest, we account for forfeitures as they occur, rather than estimate expected forfeitures.

We are also required to determine the fair value of stock-based awards at the grant date. For option awards that are subject to service conditions and/or performance conditions, we estimate the fair values of employee stock options using a Black-Scholes-Merton valuation model. Some of our option grants and awards included a market condition for which we used a Monte Carlo pricing model to establish grant date fair value. These determinations require judgment, including estimating expected volatility. If actual results differ significantly from these estimates, stock-based compensation expense and our results of operations could be impacted.

Non-GAAP Financial Measures

    Disclosure in this annual report of "Adjusted EPS," "Adjusted EBITDA," "Adjusted Net Income," and "Free Cash Flow," which are "non-GAAP financial measures" as defined under the rules of the Securities and Exchange Commission (the "SEC"), are intended as supplemental measures of our financial performance that are not required by, or presented in accordance with, U.S. generally accepted accounting principles ("GAAP"). "Adjusted Net Income" and "Adjusted fully diluted earnings per share" (or "Adjusted EPS") represents net income attributable to Thermon before costs related to the consolidation of our operating footprint in Canada, acceleration of unamortized debt costs, the tax benefit from income tax rate reductions in certain foreign jurisdictions, amortization of intangible assets, the income tax effect on any non-tax adjustments, costs associated with our restructuring and other income/(charges), and income related to the Canadian Emergency Wage Subsidy, per fully-diluted common share in the case of Adjusted EPS. "Adjusted EBITDA" represents net income attributable to Thermon before interest expense (net of interest income), income tax expense, depreciation and amortization expense, stock-based compensation expense, income attributable to non-controlling interests, costs related to the consolidation of our operating footprint in Canada, costs associated with our restructuring and other income/(charges), and income related to the Canadian Emergency Wage Subsidy. "Free cash flow" represents cash provided by operating activities less cash used for the purchase of property, plant and equipment, net of sales of rental equipment and proceeds from sales of land and buildings.

    We believe these non-GAAP financial measures are meaningful to our investors to enhance their understanding of our financial performance and are frequently used by securities analysts, investors and other interested parties to compare our performance with the performance of other companies that report Adjusted EPS, Adjusted EBITDA, or Adjusted Net Income. Adjusted EPS, Adjusted EBITDA, and Adjusted Net Income should be considered in addition to, not as substitutes for, income from operations, net income, net income per share, and other measures of financial performance reported in accordance with GAAP. We provide Free cash flow as a measure of our liquidity. Note that our calculation of Adjusted EPS, Adjusted EBITDA, Adjusted Net Income, and Free cash flow may not be comparable to similarly titled measures reported by other companies.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Our primary market risk exposures include the effect of fluctuations in foreign exchange rates, interest rates and commodity prices.

Foreign currency risk relating to operations. We transact business globally and are subject to risks associated with fluctuating foreign exchange rates. Approximately 65% of our fiscal 2021 consolidated revenues were generated by sales from our non-U.S. subsidiaries. Our non-U.S. subsidiaries generally sell their products and services in the local currency, but obtain a significant amount of their products from our manufacturing facilities located elsewhere, primarily the United States, Canada and Europe. Significant changes in the relevant exchange rates could adversely affect our margins on foreign sales of products. Our non-U.S. subsidiaries incur most of their expenses (other than intercompany expenses) in their local functional currency. These currencies include the Canadian Dollar, Euro, British Pound, Russian Ruble, Australian Dollar, South Korean Won, Chinese Renminbi, Indian Rupee, Mexican Peso, Bahraini Dinars, and Japanese Yen.

We have established a program that primarily utilizes foreign currency forward contracts to offset the risk associated with the effects of certain foreign currency exposures. Under this program, increases or decreases in our foreign currency exposures are offset by gains or losses on the forward contracts, to mitigate the possibility of foreign currency transaction gains or losses. These foreign currency exposures typically arise from intercompany transactions. Our forward contracts generally have terms of 30 days or less. We do not use forward contracts for trading purposes nor do we designate these forward contracts as hedging instruments pursuant to ASC 815. We adjust the carrying amount of all contracts to their fair value at the end of each reporting period and unrealized gains and losses are included in our results of operations for that period. These gains and losses largely offset gains and losses resulting from settlement of payments received from our foreign operations which are settled in U.S. dollars. All outstanding foreign currency forward contracts are marked to market at the end of the period with unrealized gains and losses included in other expense. The fair value is determined by quoted prices on identical forward contracts (Level 2 fair value). The balance sheet reflects unrealized gains within accounts receivable and unrealized losses within accrued liabilities. Our ultimate realized gain or loss with respect to currency fluctuations will depend on the currency exchange rates and other factors in effect as the contracts mature. As of March 31, 2021 and 2020, the notional amounts of forward contracts we held to buy U.S. dollars in exchange for other major international currencies were $16.4 million and $9.8 million, respectively.

During fiscal 2021, our largest exposures to foreign exchange rates consisted primarily of the Canadian Dollar and the Euro against the U.S. dollar. The market risk related to the foreign currency exchange rates is measured by estimating the potential impact of a 10% change in the value of the U.S. dollar relative to the local currency exchange rates. The rates used to perform this analysis were based on a weighted average of the market rates in effect during the relevant period. A 10% appreciation of the U.S. dollar relative to the Canadian Dollar would result in a net decrease in net income of $0.8 million for fiscal 2021. Conversely, a 10% depreciation of the U.S. dollar relative to the Canadian Dollar would result in a net increase in net income of $1.0 million for fiscal 2021. A 10% appreciation of the U.S. dollar relative to the Euro would result in a net decrease in net income of $0.3 million for fiscal 2021. Conversely, a 10% depreciation of the U.S. dollar relative to the Euro would result in a net increase in net income of $0.3 million for fiscal 2021.

The geographic areas outside the United States in which we operate are generally not considered to be highly inflationary. Nonetheless, these foreign operations are sensitive to fluctuations in currency exchange rates arising from, among other things, certain intercompany transactions that are generally denominated in U.S. dollars rather than their respective functional currencies. The impact of foreign currency transactions on our consolidated statements of operations were gains of $0.3 million and gains of $0.6 million in fiscal 2021 and fiscal 2020, respectively.

Because our consolidated financial results are reported in U.S. dollars, and we generate a substantial amount of our sales and earnings in other currencies, the translation of those results into U.S. dollars can result in a significant increase or decrease in the amount of those sales and earnings. In addition, fluctuations in currencies relative to the U.S. dollar may make it more difficult to perform period-to-period comparisons of our reported results of operations. In fiscal 2021, we estimate that our sales were negatively impacted by $1.7 million when compared to foreign exchange translation rates that were in effect in fiscal 2020. Foreign currency impact on revenue is calculated by comparing actual current period revenue in U.S. dollars to theoretical U.S. Dollar revenue we would have achieved based on the weighted-average foreign exchange rates in effect in the comparative prior periods for all applicable foreign currencies. In fiscal 2021, we were mostly impacted by appreciation of the U.S. dollar relative to the Euro and the depreciation of the U.S. dollar relative to the Canadian Dollar. At each balance sheet date, we translate our assets and liabilities denominated in foreign currency to U.S. dollars. The balances of our foreign equity accounts are translated at their historical value. The difference between the current rates and the historical rates are posted to our currency translation account and reflected in the shareholders' equity section of our balance sheet. The effect of foreign

37

currency translation were gains of $28.6 million in fiscal 2021 and losses of $15.5 million in fiscal 2020. Currency translation gains or losses are reported as part of comprehensive income or loss in our accompanying consolidated financial statements.

Foreign currency risks related to intercompany notes. The Company has entered into a cross currency swap for the purposes of mitigating potential exposures to currency rate fluctuations related to an intercompany note of $54.6 million with our wholly-owned Canadian subsidiary, Thermon Canada Inc. See Note 2, “Fair Value Measurements” to our consolidated financial statements included in Item 8 of this annual report for further information regarding our cross currency swap.

    Interest rate risk and foreign currency risk relating to debt. Borrowings under both our variable rate term loan B credit facility and revolving credit facility incur interest expense that is variable in relation to the LIBOR rate. The interest rate for borrowings under our term loan B credit facility was 4.75% as of March 31, 2021. Based on historical balances on our revolving credit facility, we do not anticipate that a one percent increase or decrease in our interest rate would have a significant impact on our operations. We cannot provide any assurances that historical revolver borrowings will be reflective of our future use of the revolving credit facility.

    As of March 31, 2021, we had $148.5 million of outstanding principal under our variable rate LIBOR-based term loan B credit facility. Based on the outstanding borrowings, a one percent change in the interest rate would result in a $1.4 million increase or decrease in our annual interest expense. As of March 31, 2021, we had no outstanding principal under our revolving credit facility.

    Commodity price risk. We use various commodity-based raw materials in our manufacturing processes. Generally, we acquire such components at market prices and do not typically enter into long-term purchase commitments with suppliers or hedging instruments to mitigate commodity price risk. As a result, we are subject to market risks related to changes in commodity prices and supplies of key components of our products. Historically, the costs of our primary raw materials have been stable and readily available from multiple suppliers. Typically, we have been able to pass on raw material cost increases to our customers. We cannot provide any assurance, however, that we may be able to pass along such cost increases to our customers or source sufficient amounts of key components on commercially reasonable terms or at all in the future, and if we are unable to do so, our results of operations may be adversely affected.

Report of Independent Registered Public Accounting Firm

To the Stockholders and Board of Directors

Thermon Group Holdings, Inc.:

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of Thermon Group Holdings, Inc. and subsidiaries (the Company) as of March 31, 2021 and 2020, the related consolidated statements of operations and comprehensive income/(loss), equity, and cash flows for each of the years in the three-year period ended March 31, 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 March 31, 2021 and 2020, and the results of its operations and its cash flows for each of the years in the three-year period ended March 31, 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 March 31, 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 May 27, 2021 expressed an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting.

Change in Accounting Principle

As discussed in Note 3 to the consolidated financial statements, the Company has elected to change its method of accounting for leases as of April 1, 2019 due to the adoption of Accounting Standards Update (ASU) 2016-02, “Leases” (Topic 842).

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 matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates 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 a critical audit matter 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 matter below, providing a separate opinions on the critical audit matter or on the accounts or disclosures to which it relates.

Sufficiency of audit evidence surrounding revenues recognized over time using cost-to-cost percentage of completion

As discussed in Note 4 to the consolidated financial statements, the Company recognized $114,379 thousand of revenues over time using cost-to-cost percentage of completion or time and materials methodologies, for the year ended March 31, 2021.

40

We identified the evaluation of the sufficiency of audit evidence related to revenues recognized over time using cost-to-cost percentage of completion as a critical audit matter. A high degree of subjective auditor judgment was required because of the geographical dispersion of the Company’s revenue generating activities and the extensive data compilation required to sufficiently support the revenue recognition.

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 the revenue stream. We evaluated the design and tested the effectiveness of certain internal controls over the Company’s revenue recognition process, including controls associated with contract setup, project cost accumulation, monitoring of project status, and estimated costs to complete. We assessed the recorded revenues by selecting a sample of projects and comparing the amounts recognized for consistency with underlying documentation, including contracts with customers, cost accumulation data, estimated costs to complete, and project status assessments by the project managers. We compared the estimated costs to complete to actual results to assess the Company’s ability to accurately forecast. In addition, we evaluated the sufficiency of audit evidence obtained over revenues recognized over time using cost-to-cost percentage of completion by assessing the results of procedures performed.

To the Stockholders and Board of Directors

Thermon Group Holdings, Inc.:

Opinion on Internal Control Over Financial Reporting

We have audited Thermon Group Holdings, Inc. and subsidiaries’ (the Company) internal control over financial reporting as of March 31, 2021, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of March 31, 2021, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of March 31, 2021 and 2020, the related consolidated statements of operations and comprehensive income/(loss), equity, and cash flows for each of the years in the three-year period ended March 31, 2021, and the related notes (collectively, the consolidated financial statements), and our report dated May 27, 2021 expressed an unqualified opinion on those consolidated financial statements.

Basis for Opinion

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

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control Over Financial Reporting

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

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

March 31, 2021

1. Organization and Summary of Significant Accounting Policies

Organization

On April 30, 2010, a group of investors led by entities affiliated with CHS Capital LLC ("CHS") and two other private equity firms acquired a controlling interest in Thermon Holding Corp. and its subsidiaries from Thermon Holdings, LLC ("Predecessor") for approximately $321,500 in a transaction that was financed by approximately $129,252 of equity investments by CHS, two other private equity firms and certain members of our former management team (collectively, the "management investors") and $210,000 of debt raised in an exempt Rule 144A senior secured note offering to qualified institutional investors (collectively, the "CHS Transactions"). The proceeds from the equity investments and debt financing were used both to finance the acquisition and pay related transaction costs. As a result of the CHS Transactions, Thermon Group Holdings, Inc. became the ultimate parent of Thermon Holding Corp. Thermon Group Holdings, Inc. and its direct and indirect subsidiaries are referred to collectively as "we," "our," or the "Company" herein.

Canadian Emergency Wage Subsidy

On April 11, 2020, the Canadian government officially enacted the Canadian Emergency Wage Subsidy (the “CEWS”) for the purposes of assisting employers in financial hardship due to the COVID-19 pandemic and of reducing potential lay-offs of employees. The CEWS, which was made retroactive to March 15, 2020, generally provides “eligible entities” with a wage subsidy of up to 75% of “eligible remuneration” paid to an eligible employee per week, limited to a certain weekly maximum. On September 23, 2020, the Canadian government announced that the CEWS program would be extended through the summer of 2021 and announced certain modifications to the subsidy calculation. Our Canadian operations have benefited from such wage subsidies and have received distributions from the Canadian government. During fiscal 2021, we recorded subsidies in the amount of $6,842, as an offset to the related underlying expenses and assets, accordingly.

Basis of Consolidation

The consolidated financial statements include the accounts of the Company, its subsidiaries and entities in which the Company has a controlling financial interest. The ownership of non-controlling investors is recorded as non-controlling interests. All significant inter-company balances and transactions have been eliminated in consolidation. Consolidated subsidiaries domiciled in foreign countries comprised approximately 65%, 59% and 63%, of the Company's consolidated sales for fiscal 2021, fiscal 2020 and fiscal 2019, respectively, and 65% and 61%, of the Company's consolidated total assets at March 31, 2021 and 2020, respectively.

Segment Reporting

We maintain four reportable segments based on the four geographic countries or regions in which we operate: (i) United States and Latin America ("US-LAM"), (ii) Canada, (iii) Europe, Middle East and Africa ("EMEA") and (iv) Asia-Pacific ("APAC"). Profitability within our segments is measured by operating income. See Note 19, "Segment Information" for financial data relating to our four reportable geographic segments.

Use of Estimates

The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results inevitably will differ from those estimates, and such differences may be material to the financial statements.

Cash Equivalents

47

Cash and cash equivalents consist of cash in bank and money market funds. All highly liquid investments purchased with original maturities of three months or less are considered to be cash equivalents.

Restricted Cash

    The Company maintains restricted cash related to certain letter of credit guarantees and performance bonds securing performance obligations. The following table provides a reconciliation of cash, cash equivalents, restricted cash included in prepaid expenses and other current assets and restricted cash included in other long-term assets reported within the statement of financial position that sum to the total of the same such amounts shown in the statement of cash flows.

	March 31, 2021		March 31, 2020		March 31, 2019
Cash and cash equivalents	$	40,124	$	43,237	$	31,402
Restricted cash included in prepaid expenses and other current assets	1,962		2,421		1,624
Restricted cash included in other long-term assets	364		348		815
Total cash, cash equivalents, and restricted cash shown in the statement of cash flows	$	42,450	$	46,006	$	33,841

    Amounts shown in restricted cash included in prepaid expenses and other current assets and other long-term assets represent those required to be set aside by a contractual agreement, which contain cash deposits pledged as collateral on performance bonds and letters of credit. Amounts shown in restricted cash in other long-term assets represent such agreements that require a commitment term longer than one year.

Receivables

The Company's receivables are recorded at cost when earned and represent claims against third parties that will be settled in cash. The carrying value of the Company's receivables, net of allowance for doubtful accounts, represents its estimated net realizable value. If events or changes in circumstances indicate specific receivable balances may be impaired, further consideration is given to the Company's ability to collect those balances and the allowance is adjusted accordingly. The Company has established an allowance for doubtful accounts based upon an analysis of aged receivables. Past-due receivable balances are written-off when the Company's internal collection efforts have been unsuccessful in collecting the amounts due.

The Company's primary base of customers operates in the chemical and petrochemical, oil and gas, power generation, rail and transit, and other industries; we are diversifying our customer base through numerous other end markets. Although the Company has a concentration of credit risk within these industries, the Company has not experienced significant collection losses on sales to these customers. The Company's foreign receivables are not concentrated within any one geographic segment nor are they subject to any current economic conditions that would subject the Company to unusual risk. The Company does not generally require collateral or other security from customers.

The Company performs credit evaluations of new customers and sometimes requires deposits, prepayments or use of trade letters of credit to mitigate our credit risk. Allowance for doubtful account balances were $2,074 and $834 as of March 31, 2021 and 2020, respectively. Although we have fully provided for these balances, we continue to pursue collection of these receivables.

The following table summarizes the annual changes in our allowance for doubtful accounts:

Balance at March 31, 2018		$	1,231
	Additions to reserve	354
	Write-off of uncollectible accounts	(598)
Balance at March 31, 2019		987
	Additions to reserve	674
	Write-off of uncollectible accounts	(827)
Balance at March 31, 2020		834
	Additions to reserve	1,466
	Write-off of uncollectible accounts	(226)
Balance at March 31, 2021		$	2,074

48

Inventories

Inventories, principally raw materials and finished goods, are valued at the lower of cost (weighted average cost) or net realizable value. We write down our inventory for estimated excess or obsolete inventory equal to the difference between the cost of inventory and estimated fair market value based on assumptions of future demand and market conditions. Fair market value is determined quarterly by comparing inventory levels of individual products and components to historical usage rates, current backlog and estimated future sales and by analyzing the age and potential applications of inventory, in order to identify specific products and components of inventory that are judged unlikely to be sold. Our finished goods inventory consists primarily of completed electrical cable that has been manufactured for various heat tracing solutions, as well as various types of immersion, circulation and space heaters for THS. Most of our manufactured product offerings are built to industry standard specifications that have general purpose applications and therefore are sold to a variety of customers in various industries. Some of our products, such as custom orders and ancillary components outsourced from third-party manufacturers, have more specific applications and therefore may be at a higher risk of inventory obsolescence. Inventory is written-off in the period in which the disposal occurs. Actual future write-offs of inventory may differ from estimates and calculations used to determine valuation allowances due to changes in customer demand, customer negotiations, product application, technology shifts and other factors. Historically, inventory obsolescence and potential excess cost adjustments have been within our expectations, and management does not believe that there is a reasonable likelihood that there will be a material change in future estimates or assumptions used to calculate the inventory valuation reserves.

Revenue Recognition

Effective April 1, 2018, we adopted Accounting Standards Codification Topic 606, Revenue from Contracts with Customers ("ASC 606") using the modified retrospective method and applying ASC 606 to all revenue contracts with customers which were not completed as of the date of adoption. In accordance with the modified retrospective approach, prior period amounts were not adjusted. We expect the impact of the adoption of the new standard to continue to be immaterial to revenues and net income on an ongoing basis. Please refer to Note 4 "Revenue from Contracts with Customers" for additional information.

Property, Plant and Equipment

Property, plant and equipment are stated at cost. Expenditures for renewals and improvements that significantly extend the useful life of an asset are capitalized. Expenditures for maintenance and repairs of assets are charged to operations as incurred. When assets are sold or retired, the cost and accumulated depreciation are removed from the accounts and any gain or loss is credited or charged to operations.

Depreciation is computed using the straight-line method over the following lives:

	Useful Lives in Years
Land improvements	15	-	20
Buildings and improvements	10	-	40
Machinery and equipment	3	-	25
Office furniture and equipment	3	-	10
Internally developed software	5	-	7

Goodwill and Other Intangible Assets

    We conduct a required annual review of goodwill for potential impairment in the fourth quarter, or sooner if events or changes in circumstances indicate that the fair value of a reporting unit is below its carrying value. Our reporting units are our operating segments: US-LAM, Canada, EMEA, and APAC. We have the option to perform a qualitative assessment to satisfy the annual test requirement if we believe that it is more likely than not that we do not have an impairment in any one of our reporting units. If the carrying value of a reporting unit that includes goodwill exceeds its fair value, which is determined using both the income approach and market approach, goodwill is considered impaired. The income approach determines fair value based on discounted cash flow model derived from a reporting unit’s long-term forecasted cash flows. The market approach determines fair value based on the application of earnings multiples of comparable companies to projected earnings of the reporting unit. The amount of impairment loss is measured as the difference between the carrying value and the fair value of a reporting unit but is limited to the total amount of goodwill allocated to the reporting unit. In performing the fair value analysis,

management makes various judgments, estimates and assumptions, the most significant of which is the assumption related to revenue growth rates.

The factors we considered in developing our estimates and projections for cash flows include, but are not limited to, the following: (i) macroeconomic conditions; (ii) industry and market considerations; (iii) costs, such as increases in raw materials, labor, or other costs; (iv) our overall financial performance; and, (v) other relevant entity-specific events that impact our reporting units. The determination of whether goodwill is impaired involves a significant level of judgment in the assumptions underlying the approach used to determine the estimated fair values of our reporting units. We believe that the estimates and assumptions used in our impairment assessment are reasonable; however, these assumptions are judgmental and variations in any assumptions could result in materially different calculations of fair value. We will continue to evaluate goodwill on an annual basis in our fourth quarter, and whenever events or changes in circumstances, such as significant adverse changes in operating results, market conditions, or changes in management’s business strategy indicate that there may be a probable indicator of impairment. It is possible that the assumptions used by management related to the evaluation may change or that actual results may vary significantly from management’s estimates. In fiscal 2021, 2020 and 2019, the Company determined that no impairment of goodwill existed.

Other intangible assets include indefinite lived intangible assets for which we must also perform an annual test of impairment. The Company's indefinite lived intangible assets consist primarily of trademarks. The fair value of the Company's trademarks is calculated using a "relief from royalty payments" methodology. This approach involves first estimating reasonable royalty rates for each trademark then applying these royalty rates to a net sales stream and discounting the resulting cash flows to determine the fair value. The royalty rate is estimated using both a market and income approach. The market approach relies on the existence of identifiable transactions in the marketplace involving the licensing of trademarks similar to those owned by the Company. The income approach uses a projected pretax profitability rate relevant to the licensed income stream. We believe the use of multiple valuation techniques results in a more accurate indicator of the fair value of each trademark. This fair value is then compared with the carrying value of each trademark. The results of this test during the fourth quarter of our fiscal year indicated that there was no impairment of our indefinite life intangible assets during fiscal 2021, 2020 and 2019.

Debt Issuance Costs

The Company capitalizes and defers the costs associated with establishing our debt and financing arrangements. These costs are amortized as interest expense over the life of the loan or related financing. Additionally, for any unscheduled principal payments the Company will record incremental deferred debt charges on a pro rata basis of the unamortized deferred debt balance at the time of the repayment. When debt or the contract is retired prematurely, the proportionate unamortized deferred issuance costs are expensed as loss on retirement. Deferred debt issuance costs expensed as part of interest expense for fiscal 2021, 2020 and 2019 were $1,525, $1,885 and $1,756, respectively.

Long-Lived Assets

The Company evaluates its long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of these assets is measured by comparison of the carrying amounts to the future undiscounted cash flows that the assets are expected to generate. If the long-lived assets are considered impaired, the impairment to be recognized equals the amount by which the carrying value of the asset exceeds the estimated fair value and is recorded in the period the determination was made. In fiscal 2021, 2020, and 2019, the Company determined that no impairment of long-lived assets existed.

Stock-based Compensation

We account for share-based payments to employees in accordance with ASC 718, Compensation-Stock Compensation, which requires that share-based payments (to the extent they are compensatory) be recognized in our consolidated statements of operations and comprehensive income/(loss) based on their fair values.

As required by ASC 718, we recognize stock-based compensation expense for share-based payments that are expected to vest. In determining whether an award is expected to vest, we account for forfeitures as they occur, rather than estimate expected forfeitures.

We are also required to determine the fair value of stock-based awards at the grant date. For option awards that are subject to service conditions and/or performance conditions, we estimate the fair values of employee stock options using a Black-Scholes-Merton valuation model. Some of our option grants and awards included a market condition for which we used a

50

Monte Carlo pricing model to establish grant date fair value. These determinations require judgment, including estimating expected volatility. If actual results differ significantly from these estimates, stock-based compensation expense and our results of operations could be impacted.

Income Taxes

We account for income taxes under the asset and liability method that requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been recognized in our financial statements or tax returns. Judgment is required in assessing the future tax consequences of events that have been recognized in our financial statements or tax returns. Variations in the actual outcome of these future tax consequences could materially impact our financial position, results of operations or effective tax rate.

Significant judgment is required in determining our worldwide income tax provision. In the ordinary course of a global business, there are many transactions and calculations where the ultimate tax outcome is uncertain. Some of these uncertainties arise as a consequence of revenue sharing and cost reimbursement arrangements among related entities, the process of identifying items of revenue and expense that qualify for preferential tax treatment, and segregation of foreign and domestic earnings and expenses to avoid double taxation. Although we believe that our estimates are reasonable, the final tax outcome of these matters could be different from that which is reflected in our historical income tax provisions and accruals. Such differences could have a material effect on our income tax provision and net income in the period in which such determination is made.

    In estimating future tax consequences, all expected future events are considered other than enactments of changes in tax laws or rates. Valuation allowances are established when necessary to reduce deferred tax assets to amounts which are more likely than not to be realized. We consider future growth, forecasted earnings, future taxable income, the mix of earnings in the jurisdictions in which we operate, historical earnings, taxable income in prior years, if carryback is permitted under the law, and prudent and feasible tax planning strategies in determining the need for a valuation allowance. In the event we were to determine that we would not be able to realize all or part of our net deferred tax assets in the future, an adjustment to the deferred tax assets valuation allowance would be charged to earnings in the period in which we make such a determination, or goodwill would be adjusted at our final determination of the valuation allowance related to an acquisition within the measurement period. If we later determine that it is more likely than not that the net deferred tax assets would be realized, we would reverse the applicable portion of the previously provided valuation allowance as an adjustment to earnings at such time. The amount of income tax we pay is subject to ongoing audits by federal, state and foreign tax authorities, which often result in proposed assessments. Our estimate of the potential outcome for any uncertain tax issue is highly judgmental. We account for these uncertain tax issues pursuant to ASC 740, Income Taxes, which contains a two-step approach to recognizing and measuring uncertain tax positions taken or expected to be taken in a tax return. The first step is to determine if the weight of available evidence indicates that it is more likely than not that the tax position will be sustained on audit, including resolution of any related appeals or litigation processes. The second step is to measure the tax benefit as the largest amount that is more than 50% likely to be realized upon ultimate settlement. Although we believe we have adequately reserved for our uncertain tax positions, no assurance can be given with respect to the final outcome of these matters. We adjust reserves for our uncertain tax positions due to changing facts and circumstances, such as the closing of a tax audit, judicial rulings, refinement of estimates or realization of earnings or deductions that differ from our estimates. To the extent that the final outcome of these matters is different than the amounts recorded, such differences generally will impact our provision for income taxes in the period in which such a determination is made. Our provisions for income taxes include the impact of reserve provisions and changes to reserves that are considered appropriate and also include the related interest and penalties.

During fiscal 2018, we revised our permanent reinvestment position whereby we expect to repatriate future earnings. Given the significant changes and potential opportunities to repatriate cash tax free due to H.R.1, “An Act to Provide for Reconciliation Pursuant to Titles II and V of the Concurrent Resolution on the Budget for fiscal Year 2018” (the “Tax Act”), we have reevaluated our current permanent reinvestment position. Accordingly, we will no longer assert a permanent reinvestment position in most of our foreign subsidiaries. We expect to repatriate certain earnings which will be subject to withholding taxes.  These additional withholding taxes are being recorded as an additional deferred tax liability associated with the basis difference in such jurisdictions. Please see Note 18, "Income Taxes" for more information on the impacts of the Tax Act.

Foreign Currency Transactions and Translation

Exchange rate gains and losses that result from foreign currency transactions are recognized in income as they are realized. For the Company's non-U.S. dollar functional currency subsidiaries, assets and liabilities of foreign subsidiaries are translated into U.S. dollars using year-end exchange rates. Income and expense items are translated at weighted average

51

exchange rates prevailing during the year. Adjustments resulting from translation of financial statements are reflected as a separate component of shareholders' equity.

Loss Contingencies

We accrue for probable losses from contingencies on an undiscounted basis, when such costs are considered probable of being incurred and are reasonably estimable. Legal expense related to such matters are expensed as incurred. We periodically evaluate available information, both internal and external, relative to such contingencies and adjust this accrual as necessary. Disclosure of a contingency is required if there is at least a reasonable possibility that a material loss has been incurred. In determining whether a loss should be accrued we evaluate, among other factors, the degree of probability of an unfavorable outcome and the ability to make a reasonable estimate of the amount of loss.

Warranties

The Company offers a standard warranty on product sales. Specifically, we will replace any defective product within one year from the date of purchase. Warranties on construction projects are negotiated individually, are typically one year in duration, and may include the cost of labor to replace products. Factors that affect the Company's warranty liability include the amount of sales, historical and anticipated rates of warranty claims, and cost per claim. The Company periodically assesses the adequacy of its recorded warranty liabilities and adjusts the amounts as necessary.

Research and Development

Research and development expenditures are expensed when incurred and are included in marketing, general, administrative, and engineering expenses. Research and development expenses include salaries, direct material costs incurred, plus building and other overhead expenses. The amounts expensed for fiscal 2021, fiscal 2020 and fiscal 2019 were $7,466, $8,378 and $6,289, respectively.

Shipping and Handling Cost

The Company includes shipping and handling as part of cost of sales and freight due from customers is included as part of sales.

Economic Dependence

As of March 31, 2021 and 2020, no one customer represented more than 10% of the Company's accounts receivable balance. In fiscal 2021 and 2020, no one customer represented more than 10% of sales.

Recent Accounting Pronouncements

    Leases- In February 2016, the FASB issued Accounting Standard Update 2016-02 Leases (“ASC 842”), which provides guidance on the recognition, measurement, presentation and disclosure on leases. Under the standard, substantially all leases will be reported on the balance sheet as right-of-use assets and lease liabilities. The new guidance is effective for fiscal years and interim periods within those fiscal years beginning after December 15, 2018. The Company adopted the amended guidance using the modified retrospective method as of April 1, 2019. Please refer to Note 3 "Leases" for further discussion, including the impact the adoption had on our consolidated financial statements.

    Financial Instruments- In June 2016, the FASB issued Accounting Standards Update 2016-13 Financial Instruments- Credit Losses (“ASC 326”), which amends the guidance on the impairment of financial instruments. The standard adds an impairment model, referred to as current expected credit loss, which is based on expected losses rather than incurred losses. The standard applies to most debt instruments, trade receivables, lease receivables, reinsurance receivables, financial guarantees and loan commitments. Under the guidance, companies are required to disclose credit quality indicators disaggregated by year of origination for a five-year period. The new guidance is effective for fiscal years and interim periods within those fiscal years beginning after December 15, 2019. We adopted this standard effective April 1, 2020, and such adoption did not have a material impact on our consolidated financial statements.

    Intangibles- In January 2017, the FASB issued Accounting Standards Update 2017-04 Intangibles- Goodwill and Other (“ASC 350”), which amends and simplifies the accounting for goodwill impairment by eliminating step 2 of the goodwill impairment test. Under the amended guidance, goodwill impairment will be measured as the excess of the reporting unit’s carrying value over its fair value, not to exceed the carrying amount of goodwill for that reporting unit. The changes are

52

effective for annual and interim periods beginning after December 15, 2019, and amendments should be applied prospectively. Early adoption is permitted for any impairment tests performed after January 1, 2017. We adopted this standard effective April 1, 2020, and such adoption did not have a material impact on our consolidated financial statements.

Reference Rate Reform- In March 2020, the FASB issued Accounting Standards Update 2020-04- Reference Rate Reform ("ASC 848"). The update is intended to provide temporary optional expedients and exceptions to the GAAP guidance on contract modifications and hedge accounting to ease the financial reporting burdens related to the expected market transition from the London Interbank Offered Rate (LIBOR) and other interbank offered rates to alternative reference rates. As of March 31, 2021, we have not yet elected any optional expedients provided in the standard. We will apply the accounting relief, if necessary, as relevant contract and hedge accounting relationship modifications are made during the reference rate reform transition period. We have adopted this standard effective April 1, 2020, and such adoption did not have a material impact on our consolidated financial statements.

Income Taxes- In December 2019, the FASB issued Accounting Standards Update 2019-12- Income Taxes ("ASC 740"). This ASU amends ASC 740 to add, remove, and clarify disclosure requirements related to income taxes. The new standard is effective for fiscal years beginning after December 15, 2020. We are still evaluating the impact of this new standard.

2. Fair Value Measurements

We measure fair value based on authoritative accounting guidance, which defines fair value, establishes a framework for measuring fair value and expands on required disclosures regarding fair value measurements.

Inputs are referred to as assumptions that market participants would use in pricing the asset or liability. The uses of inputs in the valuation process are categorized into a three-level fair value hierarchy.

•Level 1 — uses quoted prices in active markets for identical assets or liabilities we have the ability to access.

•Level 2 — uses observable inputs other than quoted prices in Level 1, such as quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets and liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data.

•Level 3 — uses one or more significant inputs that are unobservable and supported by little or no market activity, and that reflect the use of significant management judgment. 

Financial assets and liabilities with carrying amounts approximating fair value include cash, trade accounts receivable, accounts payable, accrued expenses and other current liabilities. The carrying amount of these financial assets and liabilities approximates fair value because of their short maturities. At March 31, 2021 and 2020, no assets or liabilities were valued using Level 3 criteria. 

    Information about our short-term debt and long-term debt that is not measured at fair value follows:

	March 31, 2021				March 31, 2020
	Carrying Value		Fair Value		Carrying Value		Fair Value		Valuation Technique
Financial Liabilities
Outstanding principal amount of senior secured credit facility	$	148,500	$	148,871	$	176,000	$	150,480	Level 2 - Market Approach

At March 31, 2021 and 2020, the fair value of our long-term debt is based on market quotes available for issuance of debt with similar terms. As the quoted price is only available for similar financial assets, the Company concluded the pricing is indirectly observable through dealers and has been classified as Level 2. The Company believes the decline in fair value as of March 31, 2020 was attributable to the economic effects of the COVID-19 pandemic.

Cross Currency Swap

The Company has entered into a long-term cross currency swap to hedge the currency rate fluctuations related to a $54,603 intercompany receivable at March 31, 2021 from our wholly-owned Canadian subsidiary, Thermon Canada Inc., maturing on October 30, 2022. Periodic principal payments are to be settled twice annually with interest payments settled

53

quarterly through the cross currency derivative contract. We do not designate the cross currency swap as a cash flow hedge under ASC 815, Derivatives and Hedging ("ASC 815"). At March 31, 2021, we recorded $5,842 of unrealized mark-to-market losses on the cross-currency swap which is reported as "Other income and expense," in the consolidated statements of operations and comprehensive income. Cross currency swap contracts are measured on a recurring basis at fair value and are classified as Level 2 measurements. Hedge assets in the amount of $1,265 and $4,011 were included in "Other long-term assets" in the consolidated balance sheet at March 31, 2021 and 2020, respectively. For the twelve months ended March 31, 2021, the loss on the long-term cross currency swap derivative contract was more than offset by unrealized gains on the intercompany note of $6,400, resulting in a net gain of $558.

Deferred Compensation Plan Assets

The Company provides a non-qualified deferred compensation plan for certain highly compensated employees where payroll contributions are made by the employees on a pre-tax basis. Please refer to Note 13 "Employee Benefits" for further discussion.

Foreign Currency Forward Contracts

We transact business in various foreign currencies and have established a program that primarily utilizes foreign currency forward contracts to offset the risk associated with fluctuations of certain foreign currencies. Under this program, increases or decreases in our foreign currency exposures are offset by gains or losses on the forward contracts to mitigate foreign currency transaction gains or losses. These foreign currency exposures typically arise from intercompany transactions. Our forward contracts generally have terms of 30 days. We do not use forward contracts for trading purposes or designate these forward contracts as hedging instruments pursuant to ASC 815. We adjust the carrying amount of all contracts to their fair value at the end of each reporting period and unrealized gains and losses are included in our results of operations for that period. These gains and losses are intended to offset gains and losses resulting from settlement of payments received from our foreign operations which are settled in U.S. dollars. All outstanding foreign currency forward contracts are marked to market at the end of the period with unrealized gains and losses included in other expense. The fair value is determined by quoted prices from active foreign currency markets (Level 2). The consolidated balance sheets reflect unrealized gains within accounts receivable, net and unrealized losses within accrued liabilities. Our ultimate realized gain or loss with respect to currency fluctuations will depend on the currency exchange rates and other factors in effect as the contracts mature. As of March 31, 2021 and 2020, the notional amounts of forward contracts as well as the related fair values were as follows:

	March 31, 2021		March 31, 2020
Russian Ruble	$	3,000	$	1,103
Euro	—		500
Canadian Dollar	5,500		1,500
South Korean Won	5,000		3,500
Mexican Peso	1,500		2,000
Australian Dollar	900		700
Great Britain Pound	500		500
Total notional amounts	$	16,400	$	9,803

	March 31, 2021				March 31, 2020
	Fair Value				Fair Value
	Assets		Liabilities		Assets		Liabilities
Foreign exchange contract forwards	$	61	$	32	$	140	$	49

    Recognized foreign currency gains or losses related to our forward contracts in the accompanying consolidated statements of operations and comprehensive income were losses of $811, $437 and $125 for fiscal 2021, fiscal 2020 and fiscal 2019, respectively. Gains and losses from our forward contracts are intended to be offset by transaction gains and losses from the settlement of transactions denominated in foreign currencies. The Company realized net foreign currency gains and (losses) of $283, $(580), and $(228) for fiscal 2021, 2020, and 2019, respectively. Foreign currency gains and losses are recorded within other expense in our consolidated statements of operations and comprehensive income.

3. Leases

    On April 1, 2019, we adopted ASC 842 utilizing the modified retrospective approach. The modified retrospective approach we selected provides a method of transition allowing for the recognition of existing leases as of the beginning of the period of adoption, and which does not require the adjustment of comparative periods. Specifically, our results for reporting periods beginning after April 1, 2019 are presented under ASC 842, while prior period amounts are not adjusted and continue to be reported in accordance with our historic accounting under ASC 840.

Description of Leases

The significant majority of our lease obligations are for real property. We lease numerous facilities relating to our operations, primarily for office, manufacturing and warehouse facilities, as well as, from time to time, both long-term and short-term employee housing. Leases for real property have terms ranging from month-to-month to ten years. We also lease various types of equipment, including vehicles, office equipment (such as copiers and postage machines), heavy warehouse equipment (such as fork lifts), heavy construction equipment (such as cranes), medium and light construction equipment used for customer project needs (such as pipe threading machines) and mobile offices and other general equipment that is normally associated with an office environment. Equipment leases generally have terms ranging from six months to five years.

Our lease agreements do not contain any material residual value guarantees or material restrictive covenants. We do not have any significant leases that have not yet commenced but that create significant rights and obligations for us.

    We lease temporary power products produced by our Thermon Power Solutions Inc. (“TPS”) division to our customers on a short-term basis. Lease contracts associated with such rental of the temporary power products have historically been month-to-month contracts without purchase options. No lease contracts in which the Company was the lessor have had an initial term in excess of one year. As such, lease revenues for temporary power products recognized under ASC 842 in fiscal 2021 did not materially differ from leases that would have been recorded under ASC 840. See Note 12 "Related-Party Transactions" for more information about TPS.

Variable Lease Payments

A majority of our lease agreements include fixed rental payments. A small number of our lease agreements include fixed rental payments that are adjusted periodically for changes in the Consumer Price Index (“CPI”). Payments based on an index or rate such as CPI are included in the lease payments based on the commencement date index or rate. Estimated changes to the index or rate during the lease term are not considered in the determination of the lease payments.

Options to Extend or Terminate Leases

Most of our real property leases include early termination options and/or one or more options to renew, with renewal terms that can extend the lease term for an additional one to five years or longer. The exercise of lease termination and renewal options is at our sole discretion. If it is reasonably certain that we will exercise such renewal options, the periods covered by such renewal options are included in the lease term and are recognized as part of our Right of Use ("ROU") assets and lease liabilities. Certain leases also include options to purchase the leased property. The depreciable life of assets and leasehold improvements are limited by the expected lease term, unless there is a transfer of title or purchase option reasonably certain of exercise.

Discount Rate

The Company's leases generally do not provide an implicit rate, and therefore the Company uses its incremental borrowing rate as the discount rate when measuring operating lease liabilities. The incremental borrowing rate represents an estimate of the interest rate the Company would incur at lease commencement to borrow an amount equal to the lease payments on a collateralized basis over the term of a lease within a particular currency environment. A large concentration of the Company's operating lease liabilities are attributed to our United States and Latin America operations. Our EMEA operations and APAC operations have limited borrowing needs and rely on cash from operations. However, the U.S. operating subsidiary can make intercompany loans if necessary from its available credit capacity given the more preferential rates available to our U.S. operating subsidiary and the ease with which funds can be drawn from the debt facilities already established within the United States. With this in mind, the Company has utilized its U.S. credit facility rate as the worldwide incremental borrowing rate. The Company used incremental borrowing rates as of April 1, 2019 for operating leases that commenced prior to April 1, 2019 to establish the lease liabilities. For operating leases that commenced during the year ended March 31, 2021, rates applicable at or close to the time of the inception of the lease were used to establish the new lease's ROU liabilities.

4. Revenue from Contracts with Customers    

    The core principle of the revenue recognition standard is to recognize revenue that reflects the consideration the Company expects to receive for goods or services when or as the promised goods or services are transferred to customers. Accounting Standards Codification Topic 606, Revenue from Contracts with Customers ("ASC 606") requires more judgment than previous guidance, as management will need to consider the terms of the contract and all relevant facts and circumstances when applying the revenue recognition standard. Management performs the following five steps when applying the revenue recognition standard: (i) identify each contract with customers, (ii) identify each performance obligation in the contracts with customers, (iii) estimate the transaction price (including any variable consideration), (iv) allocate the transaction price to each performance obligation and (v) recognize revenue as each performance obligation is satisfied.

Description of Product and Service Offerings and Revenue Recognition Policies

    We principally provide a (i) suite of products, including heating units, heating cables, tubing bundles, control systems including industry-leading customized software solutions, environmental heating solutions, process heating solutions, temporary heating and lighting, filtration, and transportation products and (ii) services, including design optimization, engineering, installation and maintenance services required to deliver comprehensive solutions to complex projects. The performance obligations associated with our product sales are generally recognized at a point in time. Where products and services are provided together under a time and materials contract, the performance obligations are satisfied over time. We also provide fixed-fee turnkey solutions consisting of products and services under which the related performance obligations are satisfied over time.

    In addition, we offer temporary power products that are designed to provide a safe and efficient means of supplying temporary electrical power distribution and lighting at energy infrastructure facilities for new construction and during maintenance and turnaround projects at operating facilities. Revenues associated with the rental of the temporary power products have historically been less than 5% of our total revenues and are recognized under ASC 842.

    Revenue is recognized when control of the promised goods or services is transferred to our customers in an amount that reflects the consideration we expect to be entitled to receive in exchange for transferring such goods or providing such services. We account for a contract when a customer provides us with a firm purchase order or other contract that identifies the goods or services to be provided, the payment terms for those services, and when collectability of the consideration due is probable. Generally, our payment terms do not exceed 30 days for product sales, while terms for our projects can vary based on milestones or other key deliverable-based increments.

Performance Obligations

    A performance obligation is a promise to provide the customer with a good or service. At contract inception, the Company will assess the goods or services promised in the contract with a customer and shall identify, as a performance obligation, each promise to transfer to the customer either: (i) a good or service (or a bundle of goods or services) or (ii) a series of distinct goods or services that are substantially the same and that have the same pattern of transfer to the customer. For contracts with multiple performance obligations, standalone selling price is generally readily observable.

    Revenue from products transferred to customers at a point in time is recognized when obligations under the terms of the contract with the customer are satisfied; generally this occurs with the transfer of control upon shipment. Revenue from

57

products transferred to customers at a point in time accounted for approximately 58.6% and 59.6% of revenue for the fiscal year ended March 31, 2021 and 2020, respectively.

    Our revenues that are recognized over time include (i) products and services which are billed on a time and materials basis, and (ii) fixed fee contracts for complex turnkey solutions. Revenue from products and services transferred to customers over time accounted for approximately 41.4% and 40.4% of revenue for the fiscal year ended March 31, 2021 and 2020, respectively.

    For our time and materials service contracts, we recognize revenues as the products and services are provided over the term of the contract and have determined that the stated rate for installation services and products is representative of the stand-alone selling price for those services and products.

    Our turnkey projects, or fixed fee projects, offer our customers a comprehensive solution for heat tracing from the initial planning stage through engineering/design, manufacture, installation and final proof-of-performance and acceptance testing. Turnkey services also include project planning, product supply, system integration, commissioning and on-going maintenance. Turnkey solutions, containing multiple deliverables, are customer specific and do not have an alternative use and present an unconditional right to payment, and thus are treated as a single performance obligation with revenues recognized over time as work progresses.

    For revenue recognized under fixed fee turnkey contracts, we measure the costs incurred that contribute towards the satisfaction of our performance obligation as a percentage of the total cost of production (the “cost-to-cost method”), and we recognize a proportionate amount of contract revenue, as the cost-to-cost method appropriately depicts performance towards satisfaction of the performance obligation. Changes to the original cost amount may be required during the life of the contract and such estimates are reviewed on a regular basis. Sales and gross profits are adjusted using the cumulative catch-up method for revisions in estimated contract costs. Reviews of estimates have not generally resulted in significant adjustments to our results of operations.

    At March 31, 2021, revenues associated with our open performance obligations totaled $114,200, representing our combined backlog and deferred revenue. Within this amount, approximately $20,774 will be earned as revenue in excess of one year. We expect to recognize the remaining revenues associated with unsatisfied or partially satisfied performance obligations within twelve months.

Pricing and Sales Incentives

    Pricing is established at or prior to the time of sale with our customers and we record sales at the agreed-upon net selling price. Generally, we do not enter into sales contracts with customers that offer sales discounts or incentives.

Optional Exemptions, Practical Expedients and Policy Elections

    We expense the incremental costs of obtaining a contract when incurred because the amortization period would be less than one year.

    The Company has elected to treat shipping and handling activities as a cost of fulfillment rather than a separate performance obligation.

    The Company has elected to exclude all sales and other similar taxes from the transaction price. Accordingly, the Company presents all collections from customers for sales and other similar taxes on a net basis, rather than having to assess whether the Company is acting as an agent or a principal in each taxing jurisdiction.

    The Company adopted ASC 606 as of April 1, 2018 using the modified retrospective method for all contracts not completed as of the date of adoption. For contracts that were modified before the effective date, the Company utilized the practical expedient to consider the aggregate effect of all modifications when identifying performance obligations and allocating transaction price.

Contract Assets and Liabilities

    Contract assets and liabilities are presented on our consolidated balance sheet. Contract assets consist of unbilled amounts resulting from sales under long-term contracts when the cost-to-cost method of revenue recognition is utilized and revenue recognized exceeds the amount billed to the customer. In addition, contract assets contain labor and material costs

58

incurred under our time and material service contracts that have not been billed to the customer. Contract liabilities represent deferred revenue from advanced customer payments or billings in excess of costs incurred or revenue earned. The Company invoices customers pursuant to the terms of their related contract. Invoiced amounts are applied to individual contracts and an associated amount is either classified as a contract asset or contract liability depending on whether the revenue associated with the amounts billed had been earned (contract asset) or not (contract liability).

    As of March 31, 2021 and 2020, contract assets were $11,379 and $10,194, respectively. There were no impairment losses recognized on our contract assets for the twelve months ended March 31, 2021 and 2020. As of March 31, 2021 and 2020, contract liabilities were $2,959 and $4,538, respectively. The majority of contract liabilities at March 31, 2020 were recognized in revenue as of March 31, 2021.    

Disaggregation of Revenue

    We disaggregate our revenue from contracts with customers by geographic location, revenues recognized at point in time and revenues recognized over time, as we believe these best depict the nature of our sales and the regions in which those sales are earned and managed.

    Disaggregation of revenues from contracts with customers for fiscal 2021, 2020 and 2019 are as follows:

	Fiscal Year Ended March 31, 2021

5. Net Income per Common Share

59

Basic net income per common share is computed by dividing net income available to Thermon Group Holdings, Inc. by the weighted average number of common shares outstanding during each period. Diluted net income per common share is computed by dividing net income available to Thermon Group Holdings, Inc. by the weighted average number of common shares and common share equivalents outstanding (if dilutive) during each period. The number of common share equivalents, which includes options and both restricted and performance stock units, is computed using the treasury stock method. With regard to the performance stock units, we assume that the associated performance targets will be met at the target level of performance for purposes of calculating diluted net income per common share until such time that it is probable that the performance target will not be met.

The reconciliations of the denominators used to calculate basic net income per common share and diluted net income per common share for fiscal 2021, 2020, and 2019, respectively, is as follows:

	Year Ended March 31, 2021		Year Ended March 31, 2020		Year Ended March 31, 2019
Basic net income per common share
Net income available to Thermon Group Holdings, Inc.	$	1,165	$	11,938	$	22,756
Weighted-average common shares outstanding	33,134,592		32,760,327		32,568,541
Basic net income per common share	$	0.04	$	0.36	$	0.70

	Year Ended March 31, 2021		Year Ended March 31, 2020		Year Ended March 31, 2019
Diluted net income per common share
Net income available to Thermon Group Holdings, Inc.	$	1,165	$	11,938	$	22,756
Weighted-average common shares outstanding	33,134,592		32,760,327		32,568,541
Common share equivalents:
Stock options issued	27,306		134,777		235,802
Restricted and performance stock units issued	179,056		253,566		249,961
Weighted average shares outstanding – dilutive	33,340,954		33,148,670		33,054,304
Diluted net income per common share	$	0.03	$	0.36	$	0.69

For the year ended March 31, 2021, 2020, and 2019, 85,322, zero and zero equity awards, respectively, were not included in the calculation of diluted net income per common share since they would have had an anti-dilutive effect.

Balance as of March 31, 2021	$	62,725	$	121,550	$	20,139	$	8,624	$	213,038

    We identified the prolonged economic effects of the COVID-19 pandemic to be an indicator of potential asset impairments in our reporting units. In the fourth quarter of fiscal 2021, we performed our annual goodwill and tangible impairment assessments including our indefinite life trademarks. We analyzed our reporting units utilizing the income approach, based on discounted future cash flows, which are derived from internal forecasts and economic expectations, and the market approach, based on market multiples of guideline public companies. The impairment test for indefinite life trademarks utilized a relief from royalty analysis based on the cash flow streams attributable to the Thermon trademark. Based on the goodwill and assets impairment assessment, the estimated fair value of our reporting units exceeded the carrying value. As such, there was no impairment of goodwill, assets or our indefinite life trademarks as of the respective reporting periods. The

61

most significant inputs in the Company's impairment test are the projected financial information, the weighted average cost of capital and market multiples for similar transactions. If the overall economic conditions, energy market or factors specific to the Company deteriorate further, it could negatively impact the Company's future impairment tests. We will continue to monitor our reporting unit's goodwill and asset valuations and test for potential impairments until the overall market conditions improve.

    Our total intangible assets at March 31, 2021, and 2020 consisted of the following:

	Gross Carrying Amount at March 31, 2021		Accumulated Amortization		Net Carrying Amount at March 31, 2021		Gross Carrying Amount at March 31, 2020		Accumulated Amortization		Net Carrying Amount at March 31, 2020

Total	$	236,105	$	132,321	$	103,784	$	218,499	$	113,953	$	104,546

Trademarks and certifications have indefinite lives. Developed technology, products, customer relationships and other intangible assets have estimated lives of 20 years, 10 years, 10 years and 6 years, respectively. The weighted average useful life for the group is 12 years. Customer relationships intangibles associated with THS, with a gross carrying amount of $11,438, have a useful life of 17 years. Intangible assets held in non-U.S. entities are valued in foreign currencies; accordingly changes in indefinite life intangible assets, such as certifications, at March 31, 2021 and 2020 were the result of foreign currency translation adjustments. Foreign currency translation adjustments also impacted finite life intangible assets held in non-U.S. entities.

The Company recorded amortization expense of $9,445, $17,773, and $20,771 in fiscal 2021, 2020 and 2019, respectively for intangible assets. Annual amortization of intangible assets for the next five years and thereafter will approximate the following:

2022	$	8,766

Less current portion	(2,500)		(2,500)
Total	$	143,017	$	169,053

Senior Secured Credit Facility

    On October 30, 2017, the Company, as a credit party and a guarantor, Thermon Holding Corp. (the “U.S. Borrower”) and Thermon Canada Inc. (the “Canadian Borrower”), as borrowers, entered into a credit agreement with several banks and other financial institutions or entities from time to time party thereto (the “Lenders”) and JPMorgan Chase Bank, N.A. as administrative agent (the “Agent”), which provides for a $250,000 seven-year term loan B facility made available to the U.S. Borrower and a $60,000 five-year senior secured revolving credit facility made available to the U.S. Borrower and the Canadian Borrower, which we refer to collectively as our “credit facility”. The proceeds of the term loan B were used to (1) pay in full $70,875 principal and interest on a previously issued term loan due April 2019; (2) repay $6,000 in unpaid principal and interest on the U.S. Borrower's revolving line of credit; (3) to fund approximately $201,900 CAD of the purchase price of the acquisition of THS and certain related real estate assets for approximately $164,900; and (4) pay certain transaction fees and expenses in connection with the THS acquisition and the credit facility.

    Interest rates and fees. The U.S. Borrower will have the option to pay interest on the term loan B facility at a base rate, plus an applicable margin, or at a rate based on LIBOR, (subject to a floor of 1.00%), plus an applicable margin. The applicable margin for base rate loans is 275 basis points and the applicable margin for LIBOR loans is 375 basis points. The end-user Borrower may borrow revolving loans in U.S. dollars and the Canadian Borrower may also borrow revolving loans in Canadian dollars. Borrowings under the revolving credit facility (a) made in U.S. dollars will bear interest at a rate equal to a base rate, plus an applicable margin of 225 basis points or at a rate based on LIBOR, plus an applicable margin of 325 basis points and (b) made in Canadian dollars will bear interest at a rate equal to a Canadian base rate, plus an applicable margin of 225 basis points or at a rate based on Canadian Dollar Offered Rate, plus an applicable margin of 325 basis points; provided, that since the completion of the fiscal quarter ended March 31, 2018, the applicable margins in each case will be determined based on a leverage-based performance grid, as set forth in the credit agreement. In addition to paying interest on outstanding principal under the revolving credit facility, the U.S. Borrower is required to pay a commitment fee in respect of any unutilized revolving commitments of 0.50% per annum based on a leverage-based performance grid.

63

    Maturity and repayment. The revolving credit facility terminates on October 28, 2022. The scheduled maturity date of the term loan facility is October 30, 2024. Commencing April 1, 2018, the term loan will amortize in equal quarterly installments of 0.25% of the $250,000 term loan, with the payment of the balance at maturity. The U.S. Borrower will be able to voluntarily prepay the principal of the term loan without penalty or premium (subject to breakage fees) at any time in whole or in part; provided that for the first six months after the October 30, 2017 closing date, the U.S. Borrower is required to pay a 1% premium for prepayments of the term loan with the proceeds of certain repricing transactions. The U.S. Borrower is required to repay the term loan with certain asset sale and insurance proceeds, certain debt proceeds and, commencing for the fiscal year ended March 31, 2019, 50% of excess cash flow (reducing to 25% if the Company’s leverage ratio is less than 4.0 to 1.0 but greater than or equal to 3.5 to 1.0 and 0% if the Company’s leverage ratio is less than 3.5 to 1.0). The remaining balance will be due at maturity of the term loan B facility on October 30, 2024.

    Accordion. The credit facility allows for incremental term loans and incremental revolving commitments in an amount not to exceed $30,000 and an unlimited additional amount that would not cause the consolidated secured leverage ratio to exceed 4.0 to 1.0 (or, if less, the maximum consolidated leverage ratio permitted by the revolving credit facility on such date).

    At March 31, 2021, we had no outstanding borrowings under our revolving credit facility for the Canadian Borrower line of credit or for the U.S. Borrower line of credit. As of March 31, 2021, we had $56,686 of available borrowing capacity under our revolving credit facility after taking into account the borrowing base, outstanding borrowings and letters of credit outstanding. The variable rate term loan bears interest at the LIBOR rate plus an applicable margin dictated by our leverage ratio (as described above). The interest rate on the variable rate term loan on March 31, 2021 was 4.75%.

    Guarantees; security. The term loan is guaranteed by the Company and all of the Company's current and future wholly-owned domestic material subsidiaries (the “U.S. Subsidiary Guarantors”), subject to certain exceptions. Obligations of the U.S. Borrower under the revolving credit facility are guaranteed by the Company and the U.S. Subsidiary Guarantors. The obligations of the Canadian Borrower under the revolving credit facility are guaranteed by the Company, the U.S. Borrower, the U.S. Subsidiary Guarantors and each of the wholly owned Canadian material subsidiaries of the Canadian Borrower, subject to certain exceptions. The term loan and the obligations of the U.S. Borrower under the revolving credit facility are secured by a first lien on all of the Company’s assets and the assets of the U.S. Subsidiary Guarantors, including 100% of the capital stock of the U.S. Subsidiary Guarantors and 65% of the capital stock of the first tier material foreign subsidiaries of the Company, the U.S. Borrower and the U.S. Subsidiary Guarantors, subject to certain exceptions. The obligations of the Canadian Borrower under the revolving credit facility are secured by a first lien on all of the Company's assets, the U.S. Subsidiary Guarantors' assets, the Canadian Borrower’s assets and the assets of the material Canadian subsidiaries of the Canadian Borrower, including 100% of the capital stock of the Canadian Borrower’s material Canadian subsidiaries.

Financial covenants. The term loan is not subject to any financial covenants. The revolving credit facility requires the Company, on a consolidated basis, to maintain certain financial covenant ratios. The Company must maintain a consolidated leverage ratio of 3.75:1.0 as measured on the last day of any fiscal quarter. In addition, on the last day of any period of four fiscal quarters, the Company must maintain a consolidated fixed charge coverage ratio of not less than 1.25:1.0. As of March 31, 2021, we were in compliance with all financial covenants of the credit facility.

Restrictive covenants.  The credit agreement governing our facility contains various restrictive covenants that, among other things, restrict or limit our ability to (subject to certain negotiated exceptions): incur additional indebtedness; grant liens; make fundamental changes; sell assets; make restricted payments including cash dividends to shareholders; enter into sales and leaseback transactions; make investments; prepay certain indebtedness; enter into transactions with affiliates; and enter into restrictive agreements.

Maturities of long-term debt principal payments are as follows for the fiscal years ended March 31:

2022	$	2,500
2023	2,500
2024	2,500
2025	141,000
2026	—
Total	$	148,500

12. Related-Party Transactions

    In connection with the TPS transaction, one of the former TPS principals (the "TPS Minority Shareholder") retained 25% of the ownership of the entities holding the TPS business unit. During the fiscal year ended March 31, 2017, this

64

individual, together with the two other former principals of TPS, were paid $5,805 in the aggregate in full satisfaction of the Company's obligations under the $5,905 non-interest bearing performance-based note issued in connection with the TPS transaction.

    On April 2, 2018, the TPS Minority Shareholder provided the Company notice that he was exercising his option to sell one-half (12.5%) of his remaining equity interest in the entities holding the TPS business unit to the Company, and such sale was completed and effective as of July 20, 2018. The terms of the April 2015 TPS purchase agreement prescribed a valuation formula for such a sale based on TPS's financial results for the 12 months ended March 31, 2018. During the first quarter of the fiscal year ended March 31, 2019, the Company paid $5,665 to purchase the 12.5% non-controlling interest.

    Similarly, on April 2, 2019, the TPS Minority Shareholder provided the Company notice in order to exercise his option to sell the entirety of his remaining equity interest (12.5% of the entities holding the TPS business unit) to the Company. The terms of the April 2015 TPS purchase agreement prescribed a valuation formula for such a sale based on TPS’s financial results for the fiscal year ended March 31, 2019. The Company paid $4,508 to purchase the remaining 12.5% non-controlling interest on August 1, 2019.

13. Employee Benefits

The Company has defined contribution plans covering substantially all domestic employees and certain foreign subsidiary employees who meet certain service and eligibility requirements. Participant benefits are 100% vested upon participation. The Company matches employee contributions, limited to 50% of the first 6% of each employee's salary contributed. The Company's matching contributions to defined contribution plans on a consolidated basis were approximately $2,561, $2,607, and $2,315 in fiscal 2021, 2020, 2019, respectively.

The Company has an incentive compensation program to provide employees with incentive pay based on the Company's ability to achieve certain sales, profitability, and safety objectives. From time to time, the compensation committee of the Board of Directors, at its sole discretion, can add additional amounts to the overall incentive pay achieved. The Company recorded approximately $2,767, $3,104, and $9,885 for incentive compensation earned and other discretionary amounts in fiscal 2021, 2020, 2019, respectively.

    The Company provides a non-qualified deferred compensation plan for certain highly compensated employees where payroll contributions are made by the employees on a pre-tax basis. Included in “Other long-term assets” in the consolidated balance sheets at March 31, 2021 and 2020 were $5,047 and $2,849, respectively, of deferred compensation plan assets held by the Company. Deferred compensation plan assets (mutual funds) are measured at fair value on a recurring basis based on quoted market prices in active markets (Level 1). The Company has a corresponding liability to participants of $4,608 and $2,886 included in “Other long-term liabilities” in the consolidated balance sheet at March 31, 2021 and 2020, respectively. Deferred compensation expense (income) included in marketing, general, administrative, and engineering were $1,564 and $(387) for the twelve months ended March 31, 2021 and 2020, respectively. Expenses and income from our deferred compensation plan were offset by unrealized gains and losses for the deferred compensation plan included in other expense on our consolidated statements of comprehensive income. Our unrealized (gains)/losses on investments were  $(1,635) and $498 for the twelve months ended March 31, 2021 and 2020, respectively.

14. Restructuring and Other Charges/(income)

During fiscal 2021, we enacted certain restructuring initiatives to align our cost structure with the decline in demand for our products and services primarily due to COVID-19 and supply/demand fluctuations in commodity prices. Moreover, during fiscal 2021, the Company terminated approximately 252 people (both hourly and salaried positions) and incurred $5,748 in one-time severance costs. These charges were recorded to restructuring and other charges/(income) in our consolidated statements of operations and comprehensive income/(loss).

In addition, we incurred $429 in lease impairment costs primarily related to one of our Canadian facilities that was substantially vacated by December 31, 2020, as the Company executed efforts to optimize its global manufacturing footprint. We also exercised the early termination option for one of our existing leases in Canada, which resulted in the remeasurement of the related right-of-use asset and lease liability and accelerated the lease amortization and expense to align with the cease use date of the facility. We substantially vacated the facility by December 31, 2020. Finally, we early terminated one of our leases in our US-LAM segment. As a result of these abandonments, we recorded a total of $381 in lease abandonment charges during fiscal 2021. We recorded these charges to restructuring and other charges/(income) in our consolidated statements of operations and comprehensive income.

Disposal of South Africa Business

65

On December 15, 2020, a Sale of Shares Agreement was entered into between one of our consolidated subsidiaries and an investor consortium (the "TSAPL Purchasers"). As a result of this agreement, 100% of the outstanding common shares of our consolidated subsidiary, Thermon South Africa Proprietary Limited (the "South Africa Business"), were sold to the TSAPL Purchasers, with aggregate proceeds of 2,500 South African Rand (ZAR), or $167, as partial satisfaction of an existing note receivable. In addition, Purchasers committed to settle operational receivables attributable to other Company subsidiaries existing at the time of sale.

After evaluating our presence in the region served by the South Africa Business, the Company decided to centralize and consolidate our business structure and streamline our organization. A member of the TSAPL Purchasers was the current general manager of the operations of the South Africa business at the time of sale. This sale is accompanied by a distribution agreement whereby the new owners of the business have agreed to distribute our products, continuing the Company's presence in the region. We believe this is an opportunity to optimize the business while pivoting to a new relationship that will better enable us to serve our customers.

As a result of the sale and in accordance with Impairment and Disposal of Long-Lived Assets ("ASC 360"), we recognized a loss on the sale of a business of $2,065, which included the impact of a currency translation adjustment of $828. This loss was recognized within restructuring and other charges/(income) on the consolidated statements of operations and comprehensive income/(loss). The reported loss on sale of stock is not deductible for tax. Prior to the disposal, the South Africa Business's results were reported within the "Europe, Middle East and Africa" segment.

Restructuring and other charges/(income) by reportable segment were as follows:

	Year Ended March 31, 2021
United States and Latin America	$	3,563
Canada	2,591
Europe, Middle East and Africa	2,459
Asia-Pacific	10
	$	8,623

Restructuring activity related to severance activity described above recorded in "Accrued liabilities" on the condensed consolidated balance sheets is summarized as follows for fiscal 2021:

Beginning balance, April 1, 2020	$	—
Costs incurred	5,748
Less cash payments	(5,091)
Ending balance, March 31, 2021	$	657

We believe we are substantially complete with accruing costs related to restructuring activities as of the end of fiscal 2021.

15. Commitments and Contingencies

At March 31, 2021, the Company had in place letter of credit guarantees and performance bonds securing performance obligations of the Company. These arrangements totaled approximately $6,905. Of this amount, $1,066 is secured by cash deposits at the Company's financial institutions and an additional $3,314 represents a reduction of the available amount of the Company's short term and long-term revolving lines of credit. Included in prepaid expenses and other current assets at March 31, 2021 and 2020, was approximately $1,667 and $2,769, respectively, of cash deposits pledged as collateral on performance bonds and letters of credit. Our Indian subsidiary also has $4,938 in customs bonds outstanding to secure the Company's customs and duties obligations in India.

    The Company has entered into information technology service agreements with several vendors. The service fees expense amounted to $1,768, $2,679, and $3,809 in fiscal 2021, 2020, 2019, respectively. The future annual service fees under the service agreements are as follows for the fiscal years ended March 31:

2022	$	1,087
2023	896
Total	$	1,983

We are involved in various legal and administrative proceedings that arise from time to time in the ordinary course of doing business. Some of these proceedings may result in fines, penalties or judgments being assessed against us, which may adversely affect our financial results. In addition, from time to time, we are involved in various disputes, which may or may not be settled prior to legal proceedings being instituted and which may result in losses in excess of accrued liabilities, if any, relating to such unresolved disputes. As of March 31, 2021, management believes that adequate reserves have been established for any probable and reasonably estimable losses. Expenses related to litigation reduce operating income. We do not believe that the outcome of any of these proceedings or disputes would have a significant adverse effect on our financial position, long-term results of operations, or cash flows. It is possible, however, that charges related to these matters could be significant to our results of operations or cash flows in any one reporting period. 

In addition to the legal proceedings described above, in January 2020, the Company received service of process in a class action application in the Superior Court of Quebec, Montreal, Canada related to certain heating elements previously manufactured by THS and incorporated into certain portable construction heaters sold by certain manufacturers. The Company believes this claim is without merit and intends to vigorously defend itself against the claim. While the Company continues to dispute the allegations, in March 2021, it reached an agreement in principle with the plaintiff and other defendants to resolve this matter without admitting to any liability; such agreement remains subject to the agreement of the parties on the terms of a definitive settlement agreement. Settlement of this matter on the agreed terms will require the Company to contribute an amount that would not have a material impact on the Company’s consolidated financial position, results of operations or cash flows. The settlement is subject to, among other things, approval by the Superior Court.

    As of March 31, 2021, the Company has accrued $4,380 as estimated additional cost related to the operational execution of a project in our US-LAM segment.

Changes in the Company's warranty reserve are as follows:

Balance at March 31, 2018	$	300
Reserve for warranties issued during the period	300
Settlements made during the period	(235)
Balance at March 31, 2019	$	365

16. Stock-Based Compensation Expense

The Board of Directors has adopted and the shareholders have approved three stock option award plans. The 2010 Thermon Group Holdings, Inc. Restricted Stock and Stock Option Plans ("2010 Plan") was approved on July 28, 2010. The plan authorized the issuance of 2,767,171 stock options or restricted shares (on a post stock split basis). On April 8, 2011, the Board of Directors approved the Thermon Group Holdings, Inc. 2011 Long-Term Incentive Plan ("2011 LTIP"). The 2011 LTIP made available 2,893,341 shares of the Company's common stock that may be awarded to employees, directors or non-employee contractor's compensation in the form of stock options or restricted stock awards. On May 21, 2020, the Board of Directors approved the Thermon Group Holdings, Inc. 2020 Long-Term Incentive Plan ("2020 LTIP"). The 2020 LTIP made available 1,400,000 shares of the Company's common stock that may be awarded to employees, directors, or non-employee contractor's compensation in the form of stock options or restricted stock awards. Collectively, the 2010 Plan, the 2011 LTIP, and the 2020 LTIP are referred to as the "Stock Plans." The Company does not hold any shares of its own stock as treasury shares. Accordingly, the vesting of restricted stock units and performance stock units and the exercise of stock options result in the issuance of additional new shares of the Company's stock.

Unvested options outstanding are scheduled to cliff vest over three years with 100% vesting on the third anniversary date of the grant. Stock options must be exercised within 10 years from date of grant. Stock options were issued with an exercise price which was equal to the market price of our common stock at the grant date. We account for forfeitures as they occur, rather than estimate expected forfeitures.

    The aggregate intrinsic value in the preceding table represents the total intrinsic value based on our closing stock price of $19.49 as of March 31, 2021, which would have been received by the option holders had all option holders exercised as of that date.

    Stock options are valued by using a Black-Scholes-Merton option pricing model. We calculate the value of our stock option awards when they are granted. Accordingly, we update our valuation assumptions for volatility and the risk free interest rate each quarter that option grants are awarded. Annually, we prepare an analysis of the historical activity within our option plans as well as the demographic characteristics of the grantees of options within our stock option plan to determine the estimated life of the grants and possible ranges of estimated forfeiture. The expected life was determined using the simplified method for estimating expected option life, which qualify as "plain-vanilla" options. The risk-free interest rate is based on the rate of a zero-coupon U.S. Treasury instrument with a remaining term approximately equal to the expected term. We do not expect to pay dividends in the near term and therefore do not incorporate the dividend yield as part of our assumptions.

Restricted Stock Awards and Units

    Restricted stock awards have been issued to members of our board of directors and restricted stock units have been issued to certain employees. For restricted stock awards, the actual common shares have been issued with voting rights and are included as part of our total common shares outstanding. The common shares may not be sold or exchanged until the vesting period is completed. For restricted stock units, no common shares are issued until the vesting period is completed. For restricted stock units, the Company allows its employees to withhold a portion of their units upon the vesting dates in order to satisfy their tax obligation. For both restricted stock awards and units, fair value is determined by the market value of our common stock on the date of the grant.

    During fiscal 2015, we established a plan to issue our directors awards of fully vested common stock in lieu of restricted stock awards. During fiscal 2021 and fiscal 2020, we issued 52,098 and 26,608 fully vested common shares which had a total fair value of $712 and $660 based on the closing price of our common stock on the date of issuance, respectively. As of March 31, 2021, there were no outstanding restricted stock awards.

69

    The following table summarizes the activity with regard to unvested restricted stock units issued to employees during fiscal 2021, fiscal 2020, and fiscal 2019.

Restricted Stock Units		Number of Shares	Weighted Average Grant Fair Value
Balance of unvested units at March 31, 2018		229,112	$	19.55
	Granted	115,378	23.44
	Released	(101,874)	19.93
	Forfeited	(5,591)	19.98
Balance of unvested units at March 31, 2019		237,025	$	21.26
	Granted	122,747	22.17
	Released	(117,216)	20.39
	Forfeited	(5,850)	21.81
Balance of unvested units at March 31, 2020		236,706	$	22.14
	Granted	222,679	13.75
	Released	(115,504)	21.33
	Forfeited	(39,357)	16.95
Balance of unvested units at March 31, 2021		304,524	$	12.96

Based on our closing stock price of $19.49, the aggregate intrinsic value of the unvested restricted stock units at March 31, 2021 was $5,935. Total unrecognized expense related to unvested restricted stock awards was approximately $2,994 as of March 31, 2021. We anticipate this expense to be recognized over a weighted average period of approximately 1.8 years.

Performance Stock Units. During fiscal 2021, 2020, and 2019, performance stock unit awards were issued to our executive officers and other members of management and had total estimated grant date fair values of $1,947, $2,285 and $1,654, respectively. For the fiscal 2021 awards, the performance indicator for these awards is a combination of stock price and the Company's Adjusted EBITDA. The target number of shares is 49,716 and 86,634 for the stock price awards and Adjusted EBITDA awards, respectively. For those awards utilizing a stock price indicator, the stock price indicator measures our stock price relative to a predetermined peer group of companies with similar business characteristics as ours. Since the stock price indicator is market-based, we prepared a Monte Carlo valuation model to calculate the probable outcome of the market for our stock to arrive at the fair value. The fair value of the market based units will be expensed over three years, whether or not the market condition is met. For those awards utilizing an Adjusted EBITDA indicator, the Adjusted EBITDA indicator establishes the target Adjusted EBITDA for each of the three years ending March 31, 2023. Since these are performance based stock awards, the Company will make estimates of periodic expense until the Adjusted EBITDA target is known and the expense for actual number of shares earned is determinable.

During fiscal 2021 and 2020, certain Adjusted EBITDA-based performance stock awards that were scheduled to vest did not meet the minimum Adjusted EBITDA indicator. Accordingly, 130,835 and 5,153 of previously outstanding performance stock units were forfeited during fiscal 2021 and 2020, respectively. For performance stock units, the performance period will end on the third fiscal year end subsequent to the award being granted. It will then be determined how many shares of stock will be issued. In each year of the performance period, the possible number of shares will range from zero percent to two hundred percent of the target shares.

70

    The following table summarized the target number of performance stock units outstanding and the minimum and maximum number of shares that can be earned as of March 31, 2021.     

Fiscal Year Granted	Target	Minimum	Maximum
Fiscal 2019	68,178	0	136,356
Fiscal 2020	92,394	0	184,788
Fiscal 2021	136,350	0	272,700

    In fiscal 2021, 2020 and 2019, the performance objectives for 4,476, 79,144 and 36,611 awards, respectively, were earned.

    At March 31, 2021, there was $1,461 in stock compensation that remained to be expensed, which will be recognized over a period of 1.5 years.

    On December 22, 2017, the United States enacted significant changes to U.S. tax law following the passage and signing of H.R.1, “An Act to Provide for Reconciliation Pursuant to Titles II and V of the Concurrent Resolution on the Budget for fiscal Year 2018” (the “Tax Act”) (previously known as “The Tax Cuts and Jobs Act”).  The Tax Act included significant changes to existing tax law, including a permanent reduction to the U.S. federal corporate income tax rate from 35% to 21%, a one-time repatriation tax on deferred foreign income (“Transition Tax”), deductions, credits and business-related exclusions. 

    Consistent with provisions allowed under the Tax Act, the net $4,007 calculated Transition Tax liability will be paid over an eight year period beginning in fiscal year 2019. At March 31, 2020, $2,478 of the Transition Tax liability is included in “Other liabilities- long-term” in the consolidated balance sheets.  

    The net benefit of $3,097 related to deferred tax assets and liabilities is primarily associated with a reduction in deferred liabilities for unamortized intangible assets. Since these intangible assets are not tax deductible, the reduction of the liability is non-cash and will not reduce future tax payments.

Given the Tax Act’s significant changes and the opportunities to repatriate cash tax free, we have reevaluated our current permanent reinvestment position. Accordingly, we no longer assert a permanent reinvestment position in most of our foreign subsidiaries. We expect to repatriate certain earnings which will be subject to withholding taxes.  At March 31, 2021 we have accrued $1,073 as an additional deferred tax liability associated with the future repatriation of earnings from jurisdictions that withhold taxes on foreign paid dividends.  

    While the Tax Act provides for a modified territorial tax system, beginning in January 1, 2018, global intangible low-taxed income, or ("GILTI"), provisions will be applied by the United States providing an incremental tax on certain foreign income. The GILTI provisions require the Company to include in its U.S. income tax return foreign subsidiary earnings in excess of an allowable return on the foreign subsidiary's tangible assets. Under GAAP, the Company is allowed to make an accounting policy choice of either (1) treating taxes due on the future U.S. inclusions in taxable income related to GILTI provisions as a current-period expense when incurred, or the period cost method, or (2) factoring such amounts into the Company's measurement of its deferred taxes, or the deferred method. The Company has selected the period cost method as its accounting policy with respect to the new GILTI tax rules.

    To provide relief for taxpayers impacted by the COVID-19 outbreak, the United States enacted the Coronavirus Aid, Relief, and Economic Security (CARES) Act on March 27, 2020. Among other provisions, the law provides relief to U.S. federal corporate taxpayers through temporary adjustments to net operating loss rules, changes to interest expense deductibility, and enhanced qualified improvement property depreciation. Under ASC 740, the Company recognized the effect of the change in tax law on existing deferred tax assets and liabilities in income from continuing operations in the interim period that includes March 27, 2020. The primary impact to the Company for CARES was our ability to fully deduct interest expense for the twelve months ended March 31, 2020.

73

During the year ended March 31, 2021, the Company recorded discrete tax benefits of $1,859 related to updated Internal Revenue Service rules regarding the United States Global intangible low-taxed income or ("GILTI tax") and related tax planning elections associated with the GILTI tax rule changes. Under the new rules, Thermon was able to reduce previously incurred GILTI tax under the high tax exception rules. Included with this benefit are certain tax elections that resulted in the reduction of previous tax expense.

During the year ended March 31, 2021, the Company incurred a taxable loss within its operations in the United States. As a result, the net operating loss was available to be carried back to the Company's 2016 tax year when the federal tax rate was 35%. The rate differential resulted in a discrete tax benefit of $1,470.

The loss on the capital stock sale of the South Africa Business, referred to in Note 14, "Restructuring and other charges/(income)," was not deductible for income tax. This resulted in approximately $526 of discrete tax expense during the fiscal 2021.

During the twelve months ended March 31, 2020, the Company recorded the impact of a prospective income tax rate reduction in the tax jurisdictions of Alberta, Canada and the Netherlands. The scheduled rate reductions of 4% and 3%, respectively, resulted in a net reduction of deferred tax liabilities of $1,231 reported as a benefit to tax expense. In fiscal 2021, the Netherlands reversed their prospective tax reduction. Accordingly, the Company adjusted its deferred tax liability resulting in additional tax expense $332.

    As of March 31, 2021, the Company had foreign tax net operating loss carry-forwards ("NOLs") of $4,421. Of this amount, $1,320 may be carried forward indefinitely. As of March 31, 2021, the tax years 2017 through 2020 remain open to examination by the major taxing jurisdictions to which we are subject.

    At March 31, 2020, reserves for uncertain tax position consisted of uncertain tax positions related to the final Transition Tax that we determined could be overturned if the calculations were examined by tax authorities. The reserves for the Transition Tax will remain subject to examination until January 2025. No reserves are expected to be released within twelve months. Activity within our reserve for uncertain tax positions as well as the penalties and interest are recorded as a component of the Company's income tax expense. A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows:

	Year Ended March 31, 2021		Year Ended March 31, 2020
Beginning balance	$	729	$	1,137
Release of reserve	—		(463)
Interest and penalties on prior reserves	79		55
Reserve for uncertain income taxes	$	808	$	729

19. Segment Information

    We operate in four reportable segments based on four geographic countries or regions in which we operate: (i) United States and Latin America ("US-LAM"), (ii) Canada, (iii) Europe, Middle East and Africa ("EMEA") and (iv) Asia-Pacific ("APAC"). Within our four reportable segments, our core products and services are focused on thermal solutions primarily related to the electrical heat tracing industry. Each of our reportable segments serves a similar class of customers, including engineering, procurement and construction companies, international and regional oil and gas companies, commercial sub-contractors, electrical component distributors and direct sales to existing plant or industrial applications. Profitability within our segments is measured by operating income. Profitability can vary in each of our reportable segments based on the competitive environment within the region, the level of corporate overhead, such as the salaries of our senior executives, and the level of research and development and marketing activities in the region, as well as the mix of products and services. For purposes of this note, revenue is attributed to individual countries or regions on the basis of the physical location and jurisdiction of organization of the subsidiary that invoices the material and services.

ITEM 9A. CONTROLS AND PROCEDURES

Disclosure Controls and Procedures

Under the supervision and with the participation of the Company's management, including its Chief Executive Officer and Chief Financial Officer, the Company has evaluated the effectiveness of the design and operation of its disclosure controls and procedures pursuant to Rule 13a-15(b) under the Exchange Act as of the end of the period covered by this annual report. Based on that evaluation, the Company's Chief Executive Officer and Chief Financial Officer have concluded that, as of the end of the period covered by this annual report, these disclosure controls and procedures were effective to provide reasonable assurance that information required to be disclosed in the reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms, and that such information is accumulated and communicated to the Company's management to allow timely decisions regarding required disclosure.

Management's Annual Report on Internal Control Over Financial Reporting

    We, as management, are responsible for establishing and maintaining adequate internal control over the Company's financial reporting, as such term is defined in Rule 13a-15(f) under the Exchange Act. Our internal control system was designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles and includes those policies and procedures that: (1) pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of the assets of the Company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the Company are being made only in accordance with authorizations of management and directors of the Company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the Company’s assets that could have a material effect on the financial statements. All internal control systems, no matter how well designed, have inherent limitations. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation.

    Management assessed the effectiveness of the Company’s internal control over financial reporting as of March 31, 2021, based on the criteria set forth in the Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission ("COSO"). Based on this assessment, management has concluded that, as of March 31, 2021, our internal control over financial reporting is effective.

    KPMG LLP, the independent registered public accounting firm that audited the Company’s consolidated financial statements as of and for the year ended March 31, 2021 included in this annual report, has issued an attestation report on the effectiveness of the Company’s internal control over financial reporting as of March 31, 2021.

Thermon Group Holdings, Inc.

2020 Long-Term Incentive Plan

Restricted Stock Unit Award Agreement

Thermon Group Holdings, Inc., a Delaware corporation (the “Company”), hereby grants to the individual (the “Holder”) named in the award notice attached hereto (the “Award Notice”) as of the date set forth in the Award Notice (the “Grant Date”), pursuant to the provisions of the Thermon Group Holdings, Inc. 2020 Long-Term Incentive Plan (the “Plan”), a restricted stock unit award (the “Award”) with respect to the shares of the Company’s common stock, par value $0.001 per share (“Stock”), in the amount set forth in the Award Notice, upon and subject to the restrictions, terms and conditions set forth in the Plan and this agreement (the “Agreement”). Capitalized terms not defined herein shall have the meanings specified in the Plan. For purposes of this Agreement, “Company Group” shall mean the Company and any Subsidiary thereof, collectively and individually. Capitalized terms not defined herein shall have the meanings specified in the Plan.

1.Award Subject to Acceptance of Agreement. The Award shall be null and void unless the Holder accepts this Agreement by executing it in the space provided on the Award Notice and returning such execution copy to the Company or, if required by the Company, electronically accepting this Agreement within the Company’s stock plan administration system according to the procedures then in effect.

2.Rights as a Stockholder. The Holder shall not be entitled to any privileges of ownership with respect to the shares of Stock subject to the Award unless and until, and only to the extent, such shares become vested pursuant to Section 3 hereof and the Holder becomes a stockholder of record with respect to such shares of Stock. The Award shall include a right to Dividend Equivalents equal to the value of any dividends paid on the Stock for which the dividend record date occurs between the Grant Date and the date the restricted stock units are settled or forfeited. Subject to vesting, each Dividend Equivalent entitles Holder to receive the equivalent cash value of any such dividends paid on the number of shares of Stock underlying the Award that are outstanding during such period. Dividend Equivalents will be accrued (without interest) and will be subject to the same conditions as the restricted stock units to which they are attributable, including, without limitation, the vesting conditions and the provisions governing the time and form of settlement of the restricted stock units.

3.Restriction Period and Vesting.

3.1    Service-Based Vesting Condition. Subject to the remainder of this Section 3, the Stock shall vest pursuant to the terms of this Agreement in accordance with the Vesting Schedule set forth in the Award Notice, provided that the Holder remains in continuous employment with the Company through the respective Vest Dates set forth in the Award Notice. The period of time prior to vesting shall be referred to herein as the “Restriction Period.”

3.2    Change in Control. Upon a Change in Control, the Award shall be subject to Section 5.8 of the Plan.

3.3    Termination of Employment

(a)    If Holder is party to an employment or other similar agreement or subject to a severance plan that sets forth the treatment of a restricted stock unit award upon termination of employment, then the treatment of this Award will be as set forth in such employment or other similar agreement or severance plan.

(b)     If Holder is not party to an employment or other similar agreement or subject to a severance plan that sets forth the treatment of a restricted stock unit award upon termination of employment or if Holder is party to an employment or other similar agreement or a severance plan that does not set forth the treatment of a restricted stock unit award upon termination of employment, then the treatment of this Award will be as follows:

(i)    Termination of Employment by the Company Group Other than for Cause, due to death or by the Company Group due to Disability. If the Holder’s employment with the Company Group terminates prior to the end of the Restriction Period by reason of the Company Group’s termination of the Holder’s employment other than for Cause, the Holder’s death or the Company Group’s termination of the Holder’s employment due to Disability, then in any such case, the portion of the Award that was not vested immediately prior to such termination of employment (the “Termination Date”) shall immediately vest on a pro-rata basis as determined by applying the following formula: (1) the product of the total number of shares of Stock subject to the Award on the Grant Date multiplied by the total number of days Holder was employed during the Restriction Period prior to the Termination Date, (2) divided by the total number of days during the Restriction Period, (3) rounded down to the nearest whole share, and (4) less the number of shares of Stock that vested prior to the Termination Date. The remainder of the Award shall be immediately forfeited by the Holder and cancelled by the Company Group.

(ii)    Termination of Employment by the Company Group for Cause or by the Holder. If the Holder’s employment with the Company Group terminates prior to the end of the Restriction Period by reason of the Company Group’s termination of the Holder’s employment for Cause or the Holder’s resignation from employment for any reason, then the portion of the Award that was not vested immediately prior to such termination of employment shall be immediately forfeited by the Holder and cancelled by the Company Group.

(c)     Definitions.

(i)     “Cause” shall have the meaning set forth in the employment agreement, if any, between the Holder and the Company Group or any severance plan applicable to the Holder; provided that if Holder is not a party to an employment agreement or subject to a severance plan that contains such definition, then “Cause” shall mean any of the following, as reasonably determined, in good faith, by the Board: (i) the prosecution via information or indictment, or, if Holder has waived any requirement of prosecution by indictment, the charge, of Holder for a felony; (ii) the theft, conversion, embezzlement or misappropriation by Holder of funds or other assets of the Company Group or any other act of fraud or dishonesty with respect to the Company Group (including facilitating or accepting any bribes or kickbacks or other acts of self-dealing); (iii) the intentional, grossly negligent or unlawful misconduct by Holder, but only to the extent that such actions or inactions (a) actually cause material harm to the Company Group; and (b) were engaged in by the Holder with knowledge that they would cause material harm to the Company Group; (iv) the violation by Holder of any law regarding employment discrimination or sexual harassment; (v) the failure by Holder to comply with any material policy generally applicable to Company Group employees, which failure is not cured in all material respects within 30 days after notice to Holder; (vi) the repeated failure by Holder to follow the reasonable

directives of any supervisor or the Board, which failure is not cured in all material respects within 30 days after notice to Holder; (vii) the unauthorized dissemination by Holder of confidential information in violation of any agreement between the Company Group and Holder; (viii) any material misrepresentation or materially misleading omission in any resume or other information regarding Holder (including Holder’s work experience, academic credentials, professional affiliations or absence of criminal record) provided by or on behalf of Holder when applying for employment with the Company Group; (ix) the Company Group’s discovery that, prior to Holder’s employment with the Company Group, Holder engaged in conduct of the type described in clauses (i) through (iv) above (it being understood that, in the case of clause (iii) above, such harm having impacted Holder’s prior employer or the Company Group); or (x) any other material breach by Holder of this Agreement that is not cured within 30 days after notice to Holder.

(ii)    “Disability” shall mean the Holder’s inability to engage in any substantial gainful activity by reason of any medically determinable physical or mental impairment which can be expected to result in death or which has lasted or can be expected to last for a continuous period of not less than 12 months.

4.     Delivery of Certificates. Subject to Section 7, as soon as practicable (but no later than sixty (60) days) after the vesting of the Award, in whole or in part, the Company shall deliver or cause to be delivered (i) one or more certificates issued in the Holder’s name (or such other name as is acceptable to the Company and designated in writing by the Holder) representing the number of vested shares, or (ii) the number of vested shares to the Holder's stock plan brokerage account that has been previously approved by the Company in its sole discretion. The Company shall pay all original issue or transfer taxes and all fees and expenses incident to such delivery, except as otherwise provided in Section 7. Prior to the issuance to the Holder of the shares of Stock subject to the Award, the Holder shall have no direct or secured claim in any specific assets of the Company or in such shares of Stock, and will have the status of a general unsecured creditor of the Company.

5.     Transfer Restrictions and Investment Representation.

5.1    Nontransferability of Award. The Award may not be transferred by the Holder other than by will or the laws of descent and distribution or pursuant to the designation of one or more beneficiaries on the form prescribed by the Company. Except to the extent permitted by the foregoing sentence, the Award may not be sold, transferred, assigned, pledged, hypothecated, encumbered or otherwise disposed of (whether by operation of law or otherwise) or be subject to execution, attachment or similar process. Upon any attempt to so sell, transfer, assign, pledge, hypothecate, encumber or otherwise dispose of the Award, the Award and all rights hereunder shall immediately become null and void.

5.2    Investment Representation. The Holder hereby represents and covenants that (a) any share of Stock acquired upon the vesting of the Award will be acquired for investment and not with a view to the distribution thereof within the meaning of the Securities Act of 1933, as amended (the “Securities Act”), unless such acquisition has been registered under the Securities Act and any applicable state securities laws; (b) any subsequent sale of any such shares shall be made either pursuant to an effective registration statement under the Securities Act and any applicable state securities laws, or pursuant to an exemption from registration under the Securities Act and such state securities laws; and (c) if requested by the Company, the Holder shall submit a written statement, in form satisfactory to the Company, to the effect that such representation (x) is true and correct as of the date of vesting of any shares of Stock hereunder or (y) is true and correct as of the date of any sale of any such share, as applicable. As a further condition precedent to the delivery to the Holder of any shares of Stock subject to

the Award, the Holder shall comply with all regulations and requirements of any regulatory authority having control of or supervision over the issuance or delivery of the shares and, in connection therewith, shall execute any documents which the Board shall in its sole discretion deem necessary or advisable.

6.    Restrictive Covenants.

6.1    Confidential Information. The Company Group’s employment of Holder has resulted and will result in Holder’s exposure and access to confidential and proprietary information, including the Company Group’s formulas, processes, administration and accounting systems, computer software, customer lists, vendor lists, due diligence files, financial information, technology, business strategies, business track record, and personal information about the Company Group’s owners, directors, officers, and employees which Holder did not have access to prior to his or her employment with the Company Group and which information is of great value to the Company Group, their owners, directors, officers, and employees. Holder shall not, other than on the Company Group’s behalf, at any time during Holder’s employment with the Company Group and thereafter, make available, divulge, disclose, or communicate in any manner whatsoever to anyone including, but not limited to, any person, firm, corporation, investor, member of the media, or entity, any such confidential or proprietary information, or use any such confidential or proprietary information for any purpose other than on the Company Group’s behalf, unless authorized to do so in writing by the Chairman of the Board, required by law or court order, or such information has become publicly available other than by reason of a breach by Holder of this Section 6.1 or of another individual’s or entity’s violation of an obligation not to disclose such information, which obligation is known to Holder. Should Holder be required by law or court order to disclose such confidential or proprietary information, Holder shall give the Company's General Counsel reasonable notice so as to allow the Company Group sufficient opportunity to challenge such application of the law or court order, or to otherwise attempt to limit the scope of such disclosure. This Agreement applies to all confidential and proprietary information of the Company Group, regardless of when such information is or was disclosed to Holder.

6.2.     Non-Competition; Non-Solicitation. During Holder’s employment with the Company Group and for a period of two (2) years thereafter Holder shall not, directly or indirectly, other than on the Company Group’s behalf:

(a)     Engage in any capacity in the Business in any country in which (i) Holder resides or has resided during the Restriction Period and (ii) any other geographic area (1) where the Company Group manufactures, markets, distributes or sells its products or renders services and (2) in which Holder provided services or support to the Company Group during the Restriction Period, within the twenty-four (24) month period ending on the last day on which Holder is in the employment of the Company Group or otherwise actively involved in the operation or management of the Business (the “Termination Date”), including as an owner, employee, partner, investor, or independent contractor, provided that nothing in this Section 6.2(a) shall prevent Holder from owning less than five percent (5%) of any class of publicly traded securities of any such business so long as such investment is passive and Holder has no other involvement with the issuer of such securities;

(b)    Induce or assist in the inducement of any employee or independent contractor, including sales representatives or agents, to terminate or otherwise limit their relationship with the Company Group; or

(c)    Solicit any customer or potential customer of the Company Group with respect to the Business. For purposes of this Section 6.2(c), a customer means any individual or entity to which the Holder had contact within the twenty-four (24) month period immediately preceding the Termination Date. For purposes of this Section 6.2(c), potential customer means any individual or entity to which the

Company Group solicited in writing within the twelve (12) month period that immediately preceded the Termination Date.

6.3     Non-Disparagement. At no time shall Holder, directly or indirectly, make (or cause to be made) to any person any disparaging, derogatory or other negative or false statement about or with respect to the Company Group (including its products, services, policies, practices, operations, employees, sales representatives, agents, officers, members, managers, partners or directors).

6.4     Patents, Copyrights, Trademarks and Other Property Rights. Any and all inventions, improvements, discoveries, formulas, technology, business strategies, management, administration, and accounting systems, processes, and computer software relating to the Company Group’s business (whether or not patentable), discovered, developed, or learned by Holder during his or her employment with the Company Group are the sole and absolute property of the Company Group and are “works made for hire” as that term is defined in the copyright laws of the United States. The Company Group is the sole and absolute owner of all patents, copyrights, trademarks, and other property rights to those items and Holder will fully assist the Company Group, at the Company Group’s cost and expense, to obtain the patents, copyrights, trademarks, or other property rights to all such inventions, improvements, discoveries, formulas, technology, business strategies, management, administration, and accounting systems, processes, or computer software. Holder has been notified by the Company Group and understands that the foregoing provisions of this Section 6.4 do not apply to an invention for which no equipment, supplies, facilities, confidential, proprietary, or trade secret information of the Company Group was used and which was developed entirely on Holder’s own time, unless the invention: (a) relates directly to the business of the Company Group; (b) relates directly to the Company Group’s actual or demonstrably anticipated research and development, or (c) results from any work performed by Holder for the Company Group.

6.5     Protected Rights. Nothing contained in this Agreement or otherwise limits Holder’s ability to report possible violations of law or regulation to, or file a charge or complaint with, the Securities and Exchange Commission, the Equal Employment Opportunity Commission, the National Labor Relations Board, the Occupational Safety and Health Administration, the Department of Justice, the Congress, any Inspector General, or any other federal, state or local governmental agency or commission (“Government Agencies”). This Agreement does not limit Holder’s ability to communicate with any Government Agencies or otherwise participate in any investigation or proceeding that may be conducted by any Government Agency, including providing documents or other information, without notice to the Company. Nothing in this Agreement shall limit Holder’s ability under applicable U.S. federal law to (a) disclose in confidence trade secrets to federal, state, and local government officials, or to an attorney, for the sole purpose of reporting or investigating a suspected violation of law or (b) disclose trade secrets in a document filed in a lawsuit or other proceeding, but only if the filing is made under seal and protected from public disclosure.

6.6     Scope of Covenants. Holder hereby acknowledges and agrees that the covenants and the territorial, time, activity and other limitations set forth in this Section 6 (or the lack thereof, as the case may be) are commercially reasonable and are properly required to protect the Company Group and its members’ respective businesses. If any such territorial, time or activity limitation (or the lack thereof) is determined to be unreasonable or otherwise unenforceable by a court or other tribunal or competent jurisdiction, the parties agree to the reduction of such territorial, time or activity limitations (including the imposition of such a limitation if it is missing) to such an area, period, scope of activity or other limitation as said court or other tribunal shall deem reasonable and enforceable under the circumstances. Also, if any member of the Company Group seeks partial enforcement of this Section 6 as to only a territory, time, scope of activity or other limitation that is reasonable, then such member of the Company Group shall be entitled to such reasonable partial enforcement. If such reduction or (if any member of the Company Group seeks partial enforcement) such partial enforcement is not possible, or if a court or other tribunal of

competent jurisdiction declines for any or no reason to grant such reduction or partial enforcement, as applicable, then the unenforceable provision or portion thereof shall be severed as provided in Section 7.13, without affecting the remaining provisions of this Agreement.

6.7.     Tolling. The period of time in which Holder is required to act, or refrain from acting, pursuant to this Section 6 shall be tolled (shall not run) for so long as Holder is in breach of any of Holder’s obligations hereunder.

6.8.     Business. For purposes of this Section 6, “Business” shall mean the business activities conducted by or planned to be undertaken by the Company Group while Holder is a holder of any Common Stock acquired pursuant to this Award or while Holder is employed by the Company Group, including any business involving (i) the design, engineering, manufacture or sale of heat tracing systems (for example, products involving the application of external heat to pipes, vessels, instruments or other equipment for the purposes of freeze protection, process temperature maintenance, environmental monitoring or surface snow and ice melting, heat tracing equipment, heat tracing tubing bundles, and heat tracing control systems), heat tracing system consultation, heat tracing system installation, heat tracing system maintenance, heat tracing insulation, (ii) the design, engineering, manufacture or sale of heating and filtration equipment for industrial and commercial applications (for example, products and services involving space and environmental heating, transportation heating, industrial process heating and gas and liquid filtration systems), and (iii) the design, engineering, manufacture, fabrication or sale of temporary power solutions and power distribution for industrial applications, and any other products sold or services provided by the Company Group and the provision of related services.

7.     Additional Terms and Conditions of Award.

7.1.     Withholding Taxes. (a) As a condition precedent to the delivery of the Stock upon the vesting of the Award, the Holder shall pay to the Company such amount as the Company may be required, under all applicable federal, state, local or other laws or regulations, to withhold and pay over as income or other withholding taxes (the “Required Tax Payments”) with respect to the Award. If the Holder shall fail to advance the Required Tax Payments, the Company may, in its discretion, deduct any Required Tax Payments from any amount then or thereafter payable by the Company to the Holder.

(b) The Holder may elect to satisfy his or her obligation to advance the Required Tax Payments by any of the following means: (i) a cash payment to the Company, (ii) delivery to the Company (either actual delivery or by attestation procedures established by the Company) of previously owned whole shares of Stock having an aggregate fair market value, determined by multiplying the number of shares of Stock delivered by the Holder by the market closing price of one share of Stock as reported on the New York Stock Exchange as of the date on which such withholding obligation arises (the “Tax Date”), equal to the Required Tax Payments, (iii) authorizing the Company to withhold whole shares of Stock which would otherwise be delivered to the Holder having an aggregate fair market value, determined by multiplying the number of shares of Stock to be withheld by the market closing price of one share of Stock as reported on the New York Stock Exchange as of the Tax Date, equal to the Required Tax Payments or (iv) any combination of (i), (ii) and (iii). Shares of Stock to be delivered or withheld may not have a fair market value in excess of the minimum amount of the Required Tax Payments. Any fraction of a share of Stock which would be required to satisfy any such obligation shall be disregarded and the remaining amount due shall be paid in cash by the Holder or deducted from any amount then or thereafter payable by the Company to the Holder. No Stock shall be delivered until the Required Tax Payments have been satisfied in full.

7.2.     Recoupment; Compensation Subject to Recovery. The Holder acknowledges that he or she has read the Company’s Policy on Recoupment of Incentive Compensation (the “Clawback Policy”). In consideration of the grant of the Award, the Holder agrees to abide by the Company’s Clawback Policy

and any determinations of the Board or the Compensation Committee pursuant to the Clawback Policy or any similar clawback or recoupment policy which the Company may adopt from time to time to the extent the Board determines in good faith that the adoption and maintenance of such policy is necessary to maintain corporate governance best practices and/or comply with the Dodd-Frank Wall Street Reform and Consumer Protection Act and implementing rules and regulations thereunder, or is otherwise required by applicable law. The Holder acknowledges and agrees that the Award received by the Holder pursuant to this Agreement shall be subject to forfeiture, recovery by the Company or other action pursuant to the Clawback Policy or any such other clawback or recoupment policy. This Section 7.2 shall survive the termination of the Holder’s employment for any reason. The foregoing remedy is in addition to and separate from any other relief available to the Company due to the Holder’s misconduct or fraud. Any determination by the Board or the Compensation Committee with respect to the foregoing shall be final, conclusive and binding upon the Holder and all persons claiming through the Holder.

7.3.     Adjustment. In the event of any equity restructuring (within the meaning of Financial Accounting Standards Board Accounting Standards Codification Topic 718, Compensation-Stock Compensation or any successor or replacement accounting standard) that causes the per share value of shares of Stock to change, such as a stock dividend, stock split, spinoff, rights offering or recapitalization through an extraordinary cash dividend, the number and class of securities subject to this Award shall be appropriately adjusted by the Committee. In the event of any other change in corporate capitalization, including a merger, consolidation, reorganization, or partial or complete liquidation of the Company, such equitable adjustments described in the foregoing sentence may be made as determined to be appropriate and equitable by the Committee to prevent dilution or enlargement of rights of Holder. In either case, the decision of the Committee regarding any such adjustment shall be final, binding and conclusive.

7.4.     Compliance with Applicable Law. The Award is subject to the condition that if the listing, registration or qualification of the shares of Stock subject to the Award upon any securities exchange or under any law, or the consent or approval of any governmental body, or the taking of any other action is necessary or desirable as a condition of, or in connection with, the delivery of shares hereunder, the shares of Stock subject to the Award shall not be delivered, in whole or in part, unless such listing, registration, qualification, consent, approval or other action shall have been effected or obtained, free of any conditions not acceptable to the Company. The Company agrees to use reasonable efforts to effect or obtain any such listing, registration, qualification, consent, approval or other action.

7.5.     Award Confers No Rights to Continued Employment. In no event shall the granting of the Award or its acceptance by the Holder, or any provision of the Agreement or the Plan, give or be deemed to give the Holder any right to continued employment by the Company, Group or any affiliate of the Company or affect in any manner the right of the Company, any Subsidiary or any affiliate of the Company to terminate the employment of any person at any time.

7.6.     Interpretation. Any dispute regarding the interpretation of this Agreement shall be submitted by the Holder or by the Company forthwith to the Committee for review. The resolution of such a dispute by the Committee shall be final and binding on all parties.

7.7.     Successors and Assigns. The Company may assign any of its rights under this Agreement to single or multiple assignees, and this Agreement shall inure to the benefit of the successors and assigns of the Company. Subject to the restrictions on transfer herein set forth, this Agreement shall be binding upon the Holder and his or her heirs, executors, administrators, successors and assigns.

7.8.     Notices. All notices, requests or other communications provided for in this Agreement shall be made, if to the Company, to Thermon Group Holdings, Inc., Attn: General Counsel, 7171 Southwest Parkway, Building 300 Suite 200, Austin, Texas 78735, and if to the Holder, to the last known mailing address of the Holder contained in the records of the Company. All notices, requests or other

communications provided for in this Agreement shall be made in writing either (a) by personal delivery, (b) by facsimile or electronic mail with confirmation of receipt, (c) bymailing in the United States mails or (d) by express courier service. The notice, request or other communication shall be deemed to be received upon personal delivery, upon confirmation of receipt of facsimile or electronic mail transmission or upon receipt by the party entitled thereto if by United States mail or express courier service; provided, however, that if a notice, request or other communication sent to the Company is not received during regular business hours, it shall be deemed to be received on the next succeeding business day of the Company.

7.9.     Governing Law. This Agreement, the Award and all determinations made and actions taken pursuant hereto and thereto, to the extent not governed by the laws of the United States, shall be governed by the laws of the State of Delaware and construed in accordance therewith without giving effect to principles of conflicts of laws.

7.10.     Personal Information. The Company may utilize a third party system to administer the Award. Holder hereby consents to the Company transmitting Holder’s personal information, including but not limited to name, date of birth, address, social security number or tax or other identification number for the purpose of facilitating the administration of the Award and to create a stock plan brokerage account in Holder's name to receive Stock in settlement of the Award. The Company currently utilizes E*TRADE for equity administration purposes, but may change providers at any time and in its sole discretion.

7.11     Agreement Subject to the Plan. This Agreement is subject to the provisions of the Plan, including Section 5.8 relating to a Change in Control, and shall be interpreted in accordance therewith. The Holder hereby acknowledges receipt of a copy of the Plan.

7.12     Entire Agreement. The Award Notice, this Agreement and the Plan constitute the entire agreement of the parties with respect to the subject matter hereof and supersede in their entirety all prior undertakings and agreements of the Company and the Holder with respect to the subject matter hereof, and may not be modified adversely to the Holder’s interest except by means of a writing signed by the Company and the Holder.

7.13.     Partial Invalidity. The invalidity or unenforceability of any particular provision of this Agreement shall not affect the other provisions hereof and this Agreement shall be construed in all respects as if such invalid or unenforceable provision was omitted.

7.14.     Amendment and Waiver. The provisions of this Agreement may be amended or waived only by the written agreement of the Company and the Holder, and no course of conduct or failure or delay in enforcing the provisions of this Agreement shall affect the validity, binding effect or enforceability of this Agreement.

7.15.     Counterparts and Electronic Delivery. The Award Notice may be executed in two counterparts each of which shall be deemed an original and both of which together shall constitute one and the same instrument. Delivery of an executed counterpart of the Award Notice by facsimile, electronic mail or other electronic transmission, including electronic acceptance within Holder’s stock plan brokerage account, shall be deemed as effective delivery of an originally executed counterpart.

7.16.     Section 409A. This Agreement is intended to be exempt from Section 409A of the Code (“Section 409A”) as a “short-term deferral” within the meaning of Treasury Regulations promulgated under Section 409A, or in the alternative to comply with Section 409A, and each settlement hereunder shall be considered a separate payment. This Agreement shall be construed and interpreted in a manner that is consistent with the requirements for avoiding additional taxes or penalties under Section 409A. Notwithstanding the foregoing, the Company makes no representations that the payments and benefits

provided under this Agreement comply with Section 409A and in no event shall the Company be liable for all or any portion of any taxes, penalties, interest or other expenses that may be incurred by the Holder on account of non-compliance with Section 409A. To the extent this Agreement provides for the Award to become vested and be settled upon the Holder’s termination of employment, the applicable shares of Stock shall be transferred to the Holder or his or her beneficiary upon the Holder’s “separation from service,” within the meaning of Section 409A of the Code; provided that if the Holder is a “specified employee,” within the meaning of Section 409A of the Code, then to the extent the Award constitutes nonqualified deferred compensation, within the meaning of Section 409A of the Code, such shares of Stock shall be transferred to the Holder or his or her beneficiary upon the earlier to occur of (i) the six-month anniversary of such separation from service and (ii) the date of the Holder’s death.

Organization and Summary of Significant Accounting Policies

Organization and Summary of Significant Accounting Policies

Organization

On April 30, 2010, a group of investors led by entities affiliated with CHS Capital LLC ("CHS") and two other private equity firms acquired a controlling interest in Thermon Holding Corp. and its subsidiaries from Thermon Holdings, LLC ("Predecessor") for approximately $321,500 in a transaction that was financed by approximately $129,252 of equity investments by CHS, two other private equity firms and certain members of our former management team (collectively, the "management investors") and $210,000 of debt raised in an exempt Rule 144A senior secured note offering to qualified institutional investors (collectively, the "CHS Transactions"). The proceeds from the equity investments and debt financing were used both to finance the acquisition and pay related transaction costs. As a result of the CHS Transactions, Thermon Group Holdings, Inc. became the ultimate parent of Thermon Holding Corp. Thermon Group Holdings, Inc. and its direct and indirect subsidiaries are referred to collectively as "we," "our," or the "Company" herein.

Canadian Emergency Wage Subsidy

On April 11, 2020, the Canadian government officially enacted the Canadian Emergency Wage Subsidy (the “CEWS”) for the purposes of assisting employers in financial hardship due to the COVID-19 pandemic and of reducing potential lay-offs of employees. The CEWS, which was made retroactive to March 15, 2020, generally provides “eligible entities” with a wage subsidy of up to 75% of “eligible remuneration” paid to an eligible employee per week, limited to a certain weekly maximum. On September 23, 2020, the Canadian government announced that the CEWS program would be extended through the summer of 2021 and announced certain modifications to the subsidy calculation. Our Canadian operations have benefited from such wage subsidies and have received distributions from the Canadian government. During fiscal 2021, we recorded subsidies in the amount of $6,842, as an offset to the related underlying expenses and assets, accordingly.

Basis of Consolidation

The consolidated financial statements include the accounts of the Company, its subsidiaries and entities in which the Company has a controlling financial interest. The ownership of non-controlling investors is recorded as non-controlling interests. All significant inter-company balances and transactions have been eliminated in consolidation. Consolidated subsidiaries domiciled in foreign countries comprised approximately 65%, 59% and 63%, of the Company's consolidated sales for fiscal 2021, fiscal 2020 and fiscal 2019, respectively, and 65% and 61%, of the Company's consolidated total assets at March 31, 2021 and 2020, respectively.

Segment Reporting

We maintain four reportable segments based on the four geographic countries or regions in which we operate: (i) United States and Latin America ("US-LAM"), (ii) Canada, (iii) Europe, Middle East and Africa ("EMEA") and (iv) Asia-Pacific ("APAC"). Profitability within our segments is measured by operating income. See Note 19, "Segment Information" for financial data relating to our four reportable geographic segments.

Use of Estimates

The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results inevitably will differ from those estimates, and such differences may be material to the financial statements.

Cash Equivalents

Cash and cash equivalents consist of cash in bank and money market funds. All highly liquid investments purchased with original maturities of three months or less are considered to be cash equivalents.

Restricted Cash

    The Company maintains restricted cash related to certain letter of credit guarantees and performance bonds securing performance obligations. The following table provides a reconciliation of cash, cash equivalents, restricted cash included in prepaid expenses and other current assets and restricted cash included in other long-term assets reported within the statement of financial position that sum to the total of the same such amounts shown in the statement of cash flows.

	March 31, 2021		March 31, 2020		March 31, 2019
Cash and cash equivalents	$	40,124	$	43,237	$	31,402
Restricted cash included in prepaid expenses and other current assets	1,962		2,421		1,624
Restricted cash included in other long-term assets	364		348		815
Total cash, cash equivalents, and restricted cash shown in the statement of cash flows	$	42,450	$	46,006	$	33,841

    Amounts shown in restricted cash included in prepaid expenses and other current assets and other long-term assets represent those required to be set aside by a contractual agreement, which contain cash deposits pledged as collateral on performance bonds and letters of credit. Amounts shown in restricted cash in other long-term assets represent such agreements that require a commitment term longer than one year.

Receivables

The Company's receivables are recorded at cost when earned and represent claims against third parties that will be settled in cash. The carrying value of the Company's receivables, net of allowance for doubtful accounts, represents its estimated net realizable value. If events or changes in circumstances indicate specific receivable balances may be impaired, further consideration is given to the Company's ability to collect those balances and the allowance is adjusted accordingly. The Company has established an allowance for doubtful accounts based upon an analysis of aged receivables. Past-due receivable balances are written-off when the Company's internal collection efforts have been unsuccessful in collecting the amounts due.

The Company's primary base of customers operates in the chemical and petrochemical, oil and gas, power generation, rail and transit, and other industries; we are diversifying our customer base through numerous other end markets. Although the Company has a concentration of credit risk within these industries, the Company has not experienced significant collection losses on sales to these customers. The Company's foreign receivables are not concentrated within any one geographic segment nor are they subject to any current economic conditions that would subject the Company to unusual risk. The Company does not generally require collateral or other security from customers.

The Company performs credit evaluations of new customers and sometimes requires deposits, prepayments or use of trade letters of credit to mitigate our credit risk. Allowance for doubtful account balances were $2,074 and $834 as of March 31, 2021 and 2020, respectively. Although we have fully provided for these balances, we continue to pursue collection of these receivables.

The following table summarizes the annual changes in our allowance for doubtful accounts:

Balance at March 31, 2018		$	1,231
	Additions to reserve	354
	Write-off of uncollectible accounts	(598)
Balance at March 31, 2019		987
	Additions to reserve	674
	Write-off of uncollectible accounts	(827)
Balance at March 31, 2020		834
	Additions to reserve	1,466
	Write-off of uncollectible accounts	(226)
Balance at March 31, 2021		$	2,074

Inventories

Inventories, principally raw materials and finished goods, are valued at the lower of cost (weighted average cost) or net realizable value. We write down our inventory for estimated excess or obsolete inventory equal to the difference between the cost of inventory and estimated fair market value based on assumptions of future demand and market conditions. Fair market value is determined quarterly by comparing inventory levels of individual products and components to historical usage rates, current backlog and estimated future sales and by analyzing the age and potential applications of inventory, in order to identify specific products and components of inventory that are judged unlikely to be sold. Our finished goods inventory consists primarily of completed electrical cable that has been manufactured for various heat tracing solutions, as well as various types of immersion, circulation and space heaters for THS. Most of our manufactured product offerings are built to industry standard specifications that have general purpose applications and therefore are sold to a variety of customers in various industries. Some of our products, such as custom orders and ancillary components outsourced from third-party manufacturers, have more specific applications and therefore may be at a higher risk of inventory obsolescence. Inventory is written-off in the period in which the disposal occurs. Actual future write-offs of inventory may differ from estimates and calculations used to determine valuation allowances due to changes in customer demand, customer negotiations, product application, technology shifts and other factors. Historically, inventory obsolescence and potential excess cost adjustments have been within our expectations, and management does not believe that there is a reasonable likelihood that there will be a material change in future estimates or assumptions used to calculate the inventory valuation reserves.

Revenue Recognition

Effective April 1, 2018, we adopted Accounting Standards Codification Topic 606, Revenue from Contracts with Customers ("ASC 606") using the modified retrospective method and applying ASC 606 to all revenue contracts with customers which were not completed as of the date of adoption. In accordance with the modified retrospective approach, prior period amounts were not adjusted. We expect the impact of the adoption of the new standard to continue to be immaterial to revenues and net income on an ongoing basis. Please refer to Note 4 "Revenue from Contracts with Customers" for additional information.

Property, Plant and Equipment

Property, plant and equipment are stated at cost. Expenditures for renewals and improvements that significantly extend the useful life of an asset are capitalized. Expenditures for maintenance and repairs of assets are charged to operations as incurred. When assets are sold or retired, the cost and accumulated depreciation are removed from the accounts and any gain or loss is credited or charged to operations.

Depreciation is computed using the straight-line method over the following lives:

	Useful Lives in Years
Land improvements	15	-	20
Buildings and improvements	10	-	40
Machinery and equipment	3	-	25
Office furniture and equipment	3	-	10
Internally developed software	5	-	7

Goodwill and Other Intangible Assets

    We conduct a required annual review of goodwill for potential impairment in the fourth quarter, or sooner if events or changes in circumstances indicate that the fair value of a reporting unit is below its carrying value. Our reporting units are our operating segments: US-LAM, Canada, EMEA, and APAC. We have the option to perform a qualitative assessment to satisfy the annual test requirement if we believe that it is more likely than not that we do not have an impairment in any one of our reporting units. If the carrying value of a reporting unit that includes goodwill exceeds its fair value, which is determined using both the income approach and market approach, goodwill is considered impaired. The income approach determines fair value based on discounted cash flow model derived from a reporting unit’s long-term forecasted cash flows. The market approach determines fair value based on the application of earnings multiples of comparable companies to projected earnings of the reporting unit. The amount of impairment loss is measured as the difference between the carrying value and the fair value of a reporting unit but is limited to the total amount of goodwill allocated to the reporting unit. In performing the fair value analysis,

management makes various judgments, estimates and assumptions, the most significant of which is the assumption related to revenue growth rates.

The factors we considered in developing our estimates and projections for cash flows include, but are not limited to, the following: (i) macroeconomic conditions; (ii) industry and market considerations; (iii) costs, such as increases in raw materials, labor, or other costs; (iv) our overall financial performance; and, (v) other relevant entity-specific events that impact our reporting units. The determination of whether goodwill is impaired involves a significant level of judgment in the assumptions underlying the approach used to determine the estimated fair values of our reporting units. We believe that the estimates and assumptions used in our impairment assessment are reasonable; however, these assumptions are judgmental and variations in any assumptions could result in materially different calculations of fair value. We will continue to evaluate goodwill on an annual basis in our fourth quarter, and whenever events or changes in circumstances, such as significant adverse changes in operating results, market conditions, or changes in management’s business strategy indicate that there may be a probable indicator of impairment. It is possible that the assumptions used by management related to the evaluation may change or that actual results may vary significantly from management’s estimates. In fiscal 2021, 2020 and 2019, the Company determined that no impairment of goodwill existed.

Other intangible assets include indefinite lived intangible assets for which we must also perform an annual test of impairment. The Company's indefinite lived intangible assets consist primarily of trademarks. The fair value of the Company's trademarks is calculated using a "relief from royalty payments" methodology. This approach involves first estimating reasonable royalty rates for each trademark then applying these royalty rates to a net sales stream and discounting the resulting cash flows to determine the fair value. The royalty rate is estimated using both a market and income approach. The market approach relies on the existence of identifiable transactions in the marketplace involving the licensing of trademarks similar to those owned by the Company. The income approach uses a projected pretax profitability rate relevant to the licensed income stream. We believe the use of multiple valuation techniques results in a more accurate indicator of the fair value of each trademark. This fair value is then compared with the carrying value of each trademark. The results of this test during the fourth quarter of our fiscal year indicated that there was no impairment of our indefinite life intangible assets during fiscal 2021, 2020 and 2019.

Debt Issuance Costs

The Company capitalizes and defers the costs associated with establishing our debt and financing arrangements. These costs are amortized as interest expense over the life of the loan or related financing. Additionally, for any unscheduled principal payments the Company will record incremental deferred debt charges on a pro rata basis of the unamortized deferred debt balance at the time of the repayment. When debt or the contract is retired prematurely, the proportionate unamortized deferred issuance costs are expensed as loss on retirement. Deferred debt issuance costs expensed as part of interest expense for fiscal 2021, 2020 and 2019 were $1,525, $1,885 and $1,756, respectively.

Long-Lived Assets

The Company evaluates its long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of these assets is measured by comparison of the carrying amounts to the future undiscounted cash flows that the assets are expected to generate. If the long-lived assets are considered impaired, the impairment to be recognized equals the amount by which the carrying value of the asset exceeds the estimated fair value and is recorded in the period the determination was made. In fiscal 2021, 2020, and 2019, the Company determined that no impairment of long-lived assets existed.

Stock-based Compensation

We account for share-based payments to employees in accordance with ASC 718, Compensation-Stock Compensation, which requires that share-based payments (to the extent they are compensatory) be recognized in our consolidated statements of operations and comprehensive income/(loss) based on their fair values.

As required by ASC 718, we recognize stock-based compensation expense for share-based payments that are expected to vest. In determining whether an award is expected to vest, we account for forfeitures as they occur, rather than estimate expected forfeitures.

We are also required to determine the fair value of stock-based awards at the grant date. For option awards that are subject to service conditions and/or performance conditions, we estimate the fair values of employee stock options using a Black-Scholes-Merton valuation model. Some of our option grants and awards included a market condition for which we used a

Monte Carlo pricing model to establish grant date fair value. These determinations require judgment, including estimating expected volatility. If actual results differ significantly from these estimates, stock-based compensation expense and our results of operations could be impacted.

Income Taxes

We account for income taxes under the asset and liability method that requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been recognized in our financial statements or tax returns. Judgment is required in assessing the future tax consequences of events that have been recognized in our financial statements or tax returns. Variations in the actual outcome of these future tax consequences could materially impact our financial position, results of operations or effective tax rate.

Significant judgment is required in determining our worldwide income tax provision. In the ordinary course of a global business, there are many transactions and calculations where the ultimate tax outcome is uncertain. Some of these uncertainties arise as a consequence of revenue sharing and cost reimbursement arrangements among related entities, the process of identifying items of revenue and expense that qualify for preferential tax treatment, and segregation of foreign and domestic earnings and expenses to avoid double taxation. Although we believe that our estimates are reasonable, the final tax outcome of these matters could be different from that which is reflected in our historical income tax provisions and accruals. Such differences could have a material effect on our income tax provision and net income in the period in which such determination is made.

    In estimating future tax consequences, all expected future events are considered other than enactments of changes in tax laws or rates. Valuation allowances are established when necessary to reduce deferred tax assets to amounts which are more likely than not to be realized. We consider future growth, forecasted earnings, future taxable income, the mix of earnings in the jurisdictions in which we operate, historical earnings, taxable income in prior years, if carryback is permitted under the law, and prudent and feasible tax planning strategies in determining the need for a valuation allowance. In the event we were to determine that we would not be able to realize all or part of our net deferred tax assets in the future, an adjustment to the deferred tax assets valuation allowance would be charged to earnings in the period in which we make such a determination, or goodwill would be adjusted at our final determination of the valuation allowance related to an acquisition within the measurement period. If we later determine that it is more likely than not that the net deferred tax assets would be realized, we would reverse the applicable portion of the previously provided valuation allowance as an adjustment to earnings at such time. The amount of income tax we pay is subject to ongoing audits by federal, state and foreign tax authorities, which often result in proposed assessments. Our estimate of the potential outcome for any uncertain tax issue is highly judgmental. We account for these uncertain tax issues pursuant to ASC 740, Income Taxes, which contains a two-step approach to recognizing and measuring uncertain tax positions taken or expected to be taken in a tax return. The first step is to determine if the weight of available evidence indicates that it is more likely than not that the tax position will be sustained on audit, including resolution of any related appeals or litigation processes. The second step is to measure the tax benefit as the largest amount that is more than 50% likely to be realized upon ultimate settlement. Although we believe we have adequately reserved for our uncertain tax positions, no assurance can be given with respect to the final outcome of these matters. We adjust reserves for our uncertain tax positions due to changing facts and circumstances, such as the closing of a tax audit, judicial rulings, refinement of estimates or realization of earnings or deductions that differ from our estimates. To the extent that the final outcome of these matters is different than the amounts recorded, such differences generally will impact our provision for income taxes in the period in which such a determination is made. Our provisions for income taxes include the impact of reserve provisions and changes to reserves that are considered appropriate and also include the related interest and penalties.

During fiscal 2018, we revised our permanent reinvestment position whereby we expect to repatriate future earnings. Given the significant changes and potential opportunities to repatriate cash tax free due to H.R.1, “An Act to Provide for Reconciliation Pursuant to Titles II and V of the Concurrent Resolution on the Budget for fiscal Year 2018” (the “Tax Act”), we have reevaluated our current permanent reinvestment position. Accordingly, we will no longer assert a permanent reinvestment position in most of our foreign subsidiaries. We expect to repatriate certain earnings which will be subject to withholding taxes.  These additional withholding taxes are being recorded as an additional deferred tax liability associated with the basis difference in such jurisdictions. Please see Note 18, "Income Taxes" for more information on the impacts of the Tax Act.

Foreign Currency Transactions and Translation

Exchange rate gains and losses that result from foreign currency transactions are recognized in income as they are realized. For the Company's non-U.S. dollar functional currency subsidiaries, assets and liabilities of foreign subsidiaries are translated into U.S. dollars using year-end exchange rates. Income and expense items are translated at weighted average

exchange rates prevailing during the year. Adjustments resulting from translation of financial statements are reflected as a separate component of shareholders' equity.

Loss Contingencies

We accrue for probable losses from contingencies on an undiscounted basis, when such costs are considered probable of being incurred and are reasonably estimable. Legal expense related to such matters are expensed as incurred. We periodically evaluate available information, both internal and external, relative to such contingencies and adjust this accrual as necessary. Disclosure of a contingency is required if there is at least a reasonable possibility that a material loss has been incurred. In determining whether a loss should be accrued we evaluate, among other factors, the degree of probability of an unfavorable outcome and the ability to make a reasonable estimate of the amount of loss.

Warranties

The Company offers a standard warranty on product sales. Specifically, we will replace any defective product within one year from the date of purchase. Warranties on construction projects are negotiated individually, are typically one year in duration, and may include the cost of labor to replace products. Factors that affect the Company's warranty liability include the amount of sales, historical and anticipated rates of warranty claims, and cost per claim. The Company periodically assesses the adequacy of its recorded warranty liabilities and adjusts the amounts as necessary.

Research and Development

Research and development expenditures are expensed when incurred and are included in marketing, general, administrative, and engineering expenses. Research and development expenses include salaries, direct material costs incurred, plus building and other overhead expenses. The amounts expensed for fiscal 2021, fiscal 2020 and fiscal 2019 were $7,466, $8,378 and $6,289, respectively.

Shipping and Handling Cost

The Company includes shipping and handling as part of cost of sales and freight due from customers is included as part of sales.

Economic Dependence

As of March 31, 2021 and 2020, no one customer represented more than 10% of the Company's accounts receivable balance. In fiscal 2021 and 2020, no one customer represented more than 10% of sales.

Recent Accounting Pronouncements

    Leases- In February 2016, the FASB issued Accounting Standard Update 2016-02 Leases (“ASC 842”), which provides guidance on the recognition, measurement, presentation and disclosure on leases. Under the standard, substantially all leases will be reported on the balance sheet as right-of-use assets and lease liabilities. The new guidance is effective for fiscal years and interim periods within those fiscal years beginning after December 15, 2018. The Company adopted the amended guidance using the modified retrospective method as of April 1, 2019. Please refer to Note 3 "Leases" for further discussion, including the impact the adoption had on our consolidated financial statements.

    Financial Instruments- In June 2016, the FASB issued Accounting Standards Update 2016-13 Financial Instruments- Credit Losses (“ASC 326”), which amends the guidance on the impairment of financial instruments. The standard adds an impairment model, referred to as current expected credit loss, which is based on expected losses rather than incurred losses. The standard applies to most debt instruments, trade receivables, lease receivables, reinsurance receivables, financial guarantees and loan commitments. Under the guidance, companies are required to disclose credit quality indicators disaggregated by year of origination for a five-year period. The new guidance is effective for fiscal years and interim periods within those fiscal years beginning after December 15, 2019. We adopted this standard effective April 1, 2020, and such adoption did not have a material impact on our consolidated financial statements.

    Intangibles- In January 2017, the FASB issued Accounting Standards Update 2017-04 Intangibles- Goodwill and Other (“ASC 350”), which amends and simplifies the accounting for goodwill impairment by eliminating step 2 of the goodwill impairment test. Under the amended guidance, goodwill impairment will be measured as the excess of the reporting unit’s carrying value over its fair value, not to exceed the carrying amount of goodwill for that reporting unit. The changes are

effective for annual and interim periods beginning after December 15, 2019, and amendments should be applied prospectively. Early adoption is permitted for any impairment tests performed after January 1, 2017. We adopted this standard effective April 1, 2020, and such adoption did not have a material impact on our consolidated financial statements.

Reference Rate Reform- In March 2020, the FASB issued Accounting Standards Update 2020-04- Reference Rate Reform ("ASC 848"). The update is intended to provide temporary optional expedients and exceptions to the GAAP guidance on contract modifications and hedge accounting to ease the financial reporting burdens related to the expected market transition from the London Interbank Offered Rate (LIBOR) and other interbank offered rates to alternative reference rates. As of March 31, 2021, we have not yet elected any optional expedients provided in the standard. We will apply the accounting relief, if necessary, as relevant contract and hedge accounting relationship modifications are made during the reference rate reform transition period. We have adopted this standard effective April 1, 2020, and such adoption did not have a material impact on our consolidated financial statements.

Income Taxes- In December 2019, the FASB issued Accounting Standards Update 2019-12- Income Taxes ("ASC 740"). This ASU amends ASC 740 to add, remove, and clarify disclosure requirements related to income taxes. The new standard is effective for fiscal years beginning after December 15, 2020. We are still evaluating the impact of this new standard.

Fair Value Measurements

12 Months Ended

Mar. 31, 2021

Fair Value Disclosures [Abstract]

Fair Value Measurements

Fair Value Measurements

We measure fair value based on authoritative accounting guidance, which defines fair value, establishes a framework for measuring fair value and expands on required disclosures regarding fair value measurements.

Inputs are referred to as assumptions that market participants would use in pricing the asset or liability. The uses of inputs in the valuation process are categorized into a three-level fair value hierarchy.

•Level 1 — uses quoted prices in active markets for identical assets or liabilities we have the ability to access.

•Level 2 — uses observable inputs other than quoted prices in Level 1, such as quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets and liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data.

•Level 3 — uses one or more significant inputs that are unobservable and supported by little or no market activity, and that reflect the use of significant management judgment. 

Financial assets and liabilities with carrying amounts approximating fair value include cash, trade accounts receivable, accounts payable, accrued expenses and other current liabilities. The carrying amount of these financial assets and liabilities approximates fair value because of their short maturities. At March 31, 2021 and 2020, no assets or liabilities were valued using Level 3 criteria. 

    Information about our short-term debt and long-term debt that is not measured at fair value follows:

	March 31, 2021				March 31, 2020
	Carrying Value		Fair Value		Carrying Value		Fair Value		Valuation Technique
Financial Liabilities
Outstanding principal amount of senior secured credit facility	$	148,500	$	148,871	$	176,000	$	150,480	Level 2 - Market Approach

At March 31, 2021 and 2020, the fair value of our long-term debt is based on market quotes available for issuance of debt with similar terms. As the quoted price is only available for similar financial assets, the Company concluded the pricing is indirectly observable through dealers and has been classified as Level 2. The Company believes the decline in fair value as of March 31, 2020 was attributable to the economic effects of the COVID-19 pandemic.

Cross Currency Swap

The Company has entered into a long-term cross currency swap to hedge the currency rate fluctuations related to a $54,603 intercompany receivable at March 31, 2021 from our wholly-owned Canadian subsidiary, Thermon Canada Inc., maturing on October 30, 2022. Periodic principal payments are to be settled twice annually with interest payments settled

quarterly through the cross currency derivative contract. We do not designate the cross currency swap as a cash flow hedge under ASC 815, Derivatives and Hedging ("ASC 815"). At March 31, 2021, we recorded $5,842 of unrealized mark-to-market losses on the cross-currency swap which is reported as "Other income and expense," in the consolidated statements of operations and comprehensive income. Cross currency swap contracts are measured on a recurring basis at fair value and are classified as Level 2 measurements. Hedge assets in the amount of $1,265 and $4,011 were included in "Other long-term assets" in the consolidated balance sheet at March 31, 2021 and 2020, respectively. For the twelve months ended March 31, 2021, the loss on the long-term cross currency swap derivative contract was more than offset by unrealized gains on the intercompany note of $6,400, resulting in a net gain of $558.

Deferred Compensation Plan Assets

The Company provides a non-qualified deferred compensation plan for certain highly compensated employees where payroll contributions are made by the employees on a pre-tax basis. Please refer to Note 13 "Employee Benefits" for further discussion.

Foreign Currency Forward Contracts

We transact business in various foreign currencies and have established a program that primarily utilizes foreign currency forward contracts to offset the risk associated with fluctuations of certain foreign currencies. Under this program, increases or decreases in our foreign currency exposures are offset by gains or losses on the forward contracts to mitigate foreign currency transaction gains or losses. These foreign currency exposures typically arise from intercompany transactions. Our forward contracts generally have terms of 30 days. We do not use forward contracts for trading purposes or designate these forward contracts as hedging instruments pursuant to ASC 815. We adjust the carrying amount of all contracts to their fair value at the end of each reporting period and unrealized gains and losses are included in our results of operations for that period. These gains and losses are intended to offset gains and losses resulting from settlement of payments received from our foreign operations which are settled in U.S. dollars. All outstanding foreign currency forward contracts are marked to market at the end of the period with unrealized gains and losses included in other expense. The fair value is determined by quoted prices from active foreign currency markets (Level 2). The consolidated balance sheets reflect unrealized gains within accounts receivable, net and unrealized losses within accrued liabilities. Our ultimate realized gain or loss with respect to currency fluctuations will depend on the currency exchange rates and other factors in effect as the contracts mature. As of March 31, 2021 and 2020, the notional amounts of forward contracts as well as the related fair values were as follows:

	March 31, 2021		March 31, 2020
Russian Ruble	$	3,000	$	1,103
Euro	—		500
Canadian Dollar	5,500		1,500
South Korean Won	5,000		3,500
Mexican Peso	1,500		2,000
Australian Dollar	900		700
Great Britain Pound	500		500
Total notional amounts	$	16,400	$	9,803

	March 31, 2021				March 31, 2020
	Fair Value				Fair Value
	Assets		Liabilities		Assets		Liabilities
Foreign exchange contract forwards	$	61	$	32	$	140	$	49

    Recognized foreign currency gains or losses related to our forward contracts in the accompanying consolidated statements of operations and comprehensive income were losses of $811, $437 and $125 for fiscal 2021, fiscal 2020 and fiscal 2019, respectively. Gains and losses from our forward contracts are intended to be offset by transaction gains and losses from the settlement of transactions denominated in foreign currencies. The Company realized net foreign currency gains and (losses) of $283, $(580), and $(228) for fiscal 2021, 2020, and 2019, respectively. Foreign currency gains and losses are recorded within other expense in our consolidated statements of operations and comprehensive income.

Leases

Leases [Abstract]

Leases

Leases

    On April 1, 2019, we adopted ASC 842 utilizing the modified retrospective approach. The modified retrospective approach we selected provides a method of transition allowing for the recognition of existing leases as of the beginning of the period of adoption, and which does not require the adjustment of comparative periods. Specifically, our results for reporting periods beginning after April 1, 2019 are presented under ASC 842, while prior period amounts are not adjusted and continue to be reported in accordance with our historic accounting under ASC 840.

Description of Leases

The significant majority of our lease obligations are for real property. We lease numerous facilities relating to our operations, primarily for office, manufacturing and warehouse facilities, as well as, from time to time, both long-term and short-term employee housing. Leases for real property have terms ranging from month-to-month to ten years. We also lease various types of equipment, including vehicles, office equipment (such as copiers and postage machines), heavy warehouse equipment (such as fork lifts), heavy construction equipment (such as cranes), medium and light construction equipment used for customer project needs (such as pipe threading machines) and mobile offices and other general equipment that is normally associated with an office environment. Equipment leases generally have terms ranging from six months to five years.

Our lease agreements do not contain any material residual value guarantees or material restrictive covenants. We do not have any significant leases that have not yet commenced but that create significant rights and obligations for us.

    We lease temporary power products produced by our Thermon Power Solutions Inc. (“TPS”) division to our customers on a short-term basis. Lease contracts associated with such rental of the temporary power products have historically been month-to-month contracts without purchase options. No lease contracts in which the Company was the lessor have had an initial term in excess of one year. As such, lease revenues for temporary power products recognized under ASC 842 in fiscal 2021 did not materially differ from leases that would have been recorded under ASC 840. See Note 12 "Related-Party Transactions" for more information about TPS.

Variable Lease Payments

A majority of our lease agreements include fixed rental payments. A small number of our lease agreements include fixed rental payments that are adjusted periodically for changes in the Consumer Price Index (“CPI”). Payments based on an index or rate such as CPI are included in the lease payments based on the commencement date index or rate. Estimated changes to the index or rate during the lease term are not considered in the determination of the lease payments.

Options to Extend or Terminate Leases

Most of our real property leases include early termination options and/or one or more options to renew, with renewal terms that can extend the lease term for an additional one to five years or longer. The exercise of lease termination and renewal options is at our sole discretion. If it is reasonably certain that we will exercise such renewal options, the periods covered by such renewal options are included in the lease term and are recognized as part of our Right of Use ("ROU") assets and lease liabilities. Certain leases also include options to purchase the leased property. The depreciable life of assets and leasehold improvements are limited by the expected lease term, unless there is a transfer of title or purchase option reasonably certain of exercise.

Discount Rate

The Company's leases generally do not provide an implicit rate, and therefore the Company uses its incremental borrowing rate as the discount rate when measuring operating lease liabilities. The incremental borrowing rate represents an estimate of the interest rate the Company would incur at lease commencement to borrow an amount equal to the lease payments on a collateralized basis over the term of a lease within a particular currency environment. A large concentration of the Company's operating lease liabilities are attributed to our United States and Latin America operations. Our EMEA operations and APAC operations have limited borrowing needs and rely on cash from operations. However, the U.S. operating subsidiary can make intercompany loans if necessary from its available credit capacity given the more preferential rates available to our U.S. operating subsidiary and the ease with which funds can be drawn from the debt facilities already established within the United States. With this in mind, the Company has utilized its U.S. credit facility rate as the worldwide incremental borrowing rate. The Company used incremental borrowing rates as of April 1, 2019 for operating leases that commenced prior to April 1, 2019 to establish the lease liabilities. For operating leases that commenced during the year ended March 31, 2021, rates applicable at or close to the time of the inception of the lease were used to establish the new lease's ROU liabilities.

Leases

Leases

    On April 1, 2019, we adopted ASC 842 utilizing the modified retrospective approach. The modified retrospective approach we selected provides a method of transition allowing for the recognition of existing leases as of the beginning of the period of adoption, and which does not require the adjustment of comparative periods. Specifically, our results for reporting periods beginning after April 1, 2019 are presented under ASC 842, while prior period amounts are not adjusted and continue to be reported in accordance with our historic accounting under ASC 840.

Description of Leases

The significant majority of our lease obligations are for real property. We lease numerous facilities relating to our operations, primarily for office, manufacturing and warehouse facilities, as well as, from time to time, both long-term and short-term employee housing. Leases for real property have terms ranging from month-to-month to ten years. We also lease various types of equipment, including vehicles, office equipment (such as copiers and postage machines), heavy warehouse equipment (such as fork lifts), heavy construction equipment (such as cranes), medium and light construction equipment used for customer project needs (such as pipe threading machines) and mobile offices and other general equipment that is normally associated with an office environment. Equipment leases generally have terms ranging from six months to five years.

Our lease agreements do not contain any material residual value guarantees or material restrictive covenants. We do not have any significant leases that have not yet commenced but that create significant rights and obligations for us.

    We lease temporary power products produced by our Thermon Power Solutions Inc. (“TPS”) division to our customers on a short-term basis. Lease contracts associated with such rental of the temporary power products have historically been month-to-month contracts without purchase options. No lease contracts in which the Company was the lessor have had an initial term in excess of one year. As such, lease revenues for temporary power products recognized under ASC 842 in fiscal 2021 did not materially differ from leases that would have been recorded under ASC 840. See Note 12 "Related-Party Transactions" for more information about TPS.

Variable Lease Payments

A majority of our lease agreements include fixed rental payments. A small number of our lease agreements include fixed rental payments that are adjusted periodically for changes in the Consumer Price Index (“CPI”). Payments based on an index or rate such as CPI are included in the lease payments based on the commencement date index or rate. Estimated changes to the index or rate during the lease term are not considered in the determination of the lease payments.

Options to Extend or Terminate Leases

Most of our real property leases include early termination options and/or one or more options to renew, with renewal terms that can extend the lease term for an additional one to five years or longer. The exercise of lease termination and renewal options is at our sole discretion. If it is reasonably certain that we will exercise such renewal options, the periods covered by such renewal options are included in the lease term and are recognized as part of our Right of Use ("ROU") assets and lease liabilities. Certain leases also include options to purchase the leased property. The depreciable life of assets and leasehold improvements are limited by the expected lease term, unless there is a transfer of title or purchase option reasonably certain of exercise.

Discount Rate

The Company's leases generally do not provide an implicit rate, and therefore the Company uses its incremental borrowing rate as the discount rate when measuring operating lease liabilities. The incremental borrowing rate represents an estimate of the interest rate the Company would incur at lease commencement to borrow an amount equal to the lease payments on a collateralized basis over the term of a lease within a particular currency environment. A large concentration of the Company's operating lease liabilities are attributed to our United States and Latin America operations. Our EMEA operations and APAC operations have limited borrowing needs and rely on cash from operations. However, the U.S. operating subsidiary can make intercompany loans if necessary from its available credit capacity given the more preferential rates available to our U.S. operating subsidiary and the ease with which funds can be drawn from the debt facilities already established within the United States. With this in mind, the Company has utilized its U.S. credit facility rate as the worldwide incremental borrowing rate. The Company used incremental borrowing rates as of April 1, 2019 for operating leases that commenced prior to April 1, 2019 to establish the lease liabilities. For operating leases that commenced during the year ended March 31, 2021, rates applicable at or close to the time of the inception of the lease were used to establish the new lease's ROU liabilities.

Revenue from Contracts with Customers

12 Months Ended

Revenue from Contract with Customer [Abstract]

Revenue from Contract with Customers

Revenue from Contracts with Customers    

    The core principle of the revenue recognition standard is to recognize revenue that reflects the consideration the Company expects to receive for goods or services when or as the promised goods or services are transferred to customers. Accounting Standards Codification Topic 606, Revenue from Contracts with Customers ("ASC 606") requires more judgment than previous guidance, as management will need to consider the terms of the contract and all relevant facts and circumstances when applying the revenue recognition standard. Management performs the following five steps when applying the revenue recognition standard: (i) identify each contract with customers, (ii) identify each performance obligation in the contracts with customers, (iii) estimate the transaction price (including any variable consideration), (iv) allocate the transaction price to each performance obligation and (v) recognize revenue as each performance obligation is satisfied.

Description of Product and Service Offerings and Revenue Recognition Policies

    We principally provide a (i) suite of products, including heating units, heating cables, tubing bundles, control systems including industry-leading customized software solutions, environmental heating solutions, process heating solutions, temporary heating and lighting, filtration, and transportation products and (ii) services, including design optimization, engineering, installation and maintenance services required to deliver comprehensive solutions to complex projects. The performance obligations associated with our product sales are generally recognized at a point in time. Where products and services are provided together under a time and materials contract, the performance obligations are satisfied over time. We also provide fixed-fee turnkey solutions consisting of products and services under which the related performance obligations are satisfied over time.

    In addition, we offer temporary power products that are designed to provide a safe and efficient means of supplying temporary electrical power distribution and lighting at energy infrastructure facilities for new construction and during maintenance and turnaround projects at operating facilities. Revenues associated with the rental of the temporary power products have historically been less than 5% of our total revenues and are recognized under ASC 842.

    Revenue is recognized when control of the promised goods or services is transferred to our customers in an amount that reflects the consideration we expect to be entitled to receive in exchange for transferring such goods or providing such services. We account for a contract when a customer provides us with a firm purchase order or other contract that identifies the goods or services to be provided, the payment terms for those services, and when collectability of the consideration due is probable. Generally, our payment terms do not exceed 30 days for product sales, while terms for our projects can vary based on milestones or other key deliverable-based increments.

Performance Obligations

    A performance obligation is a promise to provide the customer with a good or service. At contract inception, the Company will assess the goods or services promised in the contract with a customer and shall identify, as a performance obligation, each promise to transfer to the customer either: (i) a good or service (or a bundle of goods or services) or (ii) a series of distinct goods or services that are substantially the same and that have the same pattern of transfer to the customer. For contracts with multiple performance obligations, standalone selling price is generally readily observable.

    Revenue from products transferred to customers at a point in time is recognized when obligations under the terms of the contract with the customer are satisfied; generally this occurs with the transfer of control upon shipment. Revenue from

products transferred to customers at a point in time accounted for approximately 58.6% and 59.6% of revenue for the fiscal year ended March 31, 2021 and 2020, respectively.

    Our revenues that are recognized over time include (i) products and services which are billed on a time and materials basis, and (ii) fixed fee contracts for complex turnkey solutions. Revenue from products and services transferred to customers over time accounted for approximately 41.4% and 40.4% of revenue for the fiscal year ended March 31, 2021 and 2020, respectively.

    For our time and materials service contracts, we recognize revenues as the products and services are provided over the term of the contract and have determined that the stated rate for installation services and products is representative of the stand-alone selling price for those services and products.

    Our turnkey projects, or fixed fee projects, offer our customers a comprehensive solution for heat tracing from the initial planning stage through engineering/design, manufacture, installation and final proof-of-performance and acceptance testing. Turnkey services also include project planning, product supply, system integration, commissioning and on-going maintenance. Turnkey solutions, containing multiple deliverables, are customer specific and do not have an alternative use and present an unconditional right to payment, and thus are treated as a single performance obligation with revenues recognized over time as work progresses.

    For revenue recognized under fixed fee turnkey contracts, we measure the costs incurred that contribute towards the satisfaction of our performance obligation as a percentage of the total cost of production (the “cost-to-cost method”), and we recognize a proportionate amount of contract revenue, as the cost-to-cost method appropriately depicts performance towards satisfaction of the performance obligation. Changes to the original cost amount may be required during the life of the contract and such estimates are reviewed on a regular basis. Sales and gross profits are adjusted using the cumulative catch-up method for revisions in estimated contract costs. Reviews of estimates have not generally resulted in significant adjustments to our results of operations.

    At March 31, 2021, revenues associated with our open performance obligations totaled $114,200, representing our combined backlog and deferred revenue. Within this amount, approximately $20,774 will be earned as revenue in excess of one year. We expect to recognize the remaining revenues associated with unsatisfied or partially satisfied performance obligations within twelve months.

Pricing and Sales Incentives

    Pricing is established at or prior to the time of sale with our customers and we record sales at the agreed-upon net selling price. Generally, we do not enter into sales contracts with customers that offer sales discounts or incentives.

Optional Exemptions, Practical Expedients and Policy Elections

    We expense the incremental costs of obtaining a contract when incurred because the amortization period would be less than one year.

    The Company has elected to treat shipping and handling activities as a cost of fulfillment rather than a separate performance obligation.

    The Company has elected to exclude all sales and other similar taxes from the transaction price. Accordingly, the Company presents all collections from customers for sales and other similar taxes on a net basis, rather than having to assess whether the Company is acting as an agent or a principal in each taxing jurisdiction.

    The Company adopted ASC 606 as of April 1, 2018 using the modified retrospective method for all contracts not completed as of the date of adoption. For contracts that were modified before the effective date, the Company utilized the practical expedient to consider the aggregate effect of all modifications when identifying performance obligations and allocating transaction price.

Contract Assets and Liabilities

    Contract assets and liabilities are presented on our consolidated balance sheet. Contract assets consist of unbilled amounts resulting from sales under long-term contracts when the cost-to-cost method of revenue recognition is utilized and revenue recognized exceeds the amount billed to the customer. In addition, contract assets contain labor and material costs

incurred under our time and material service contracts that have not been billed to the customer. Contract liabilities represent deferred revenue from advanced customer payments or billings in excess of costs incurred or revenue earned. The Company invoices customers pursuant to the terms of their related contract. Invoiced amounts are applied to individual contracts and an associated amount is either classified as a contract asset or contract liability depending on whether the revenue associated with the amounts billed had been earned (contract asset) or not (contract liability).

    As of March 31, 2021 and 2020, contract assets were $11,379 and $10,194, respectively. There were no impairment losses recognized on our contract assets for the twelve months ended March 31, 2021 and 2020. As of March 31, 2021 and 2020, contract liabilities were $2,959 and $4,538, respectively. The majority of contract liabilities at March 31, 2020 were recognized in revenue as of March 31, 2021.    

Disaggregation of Revenue

    We disaggregate our revenue from contracts with customers by geographic location, revenues recognized at point in time and revenues recognized over time, as we believe these best depict the nature of our sales and the regions in which those sales are earned and managed.

    Disaggregation of revenues from contracts with customers for fiscal 2021, 2020 and 2019 are as follows:

Earnings Per Share [Abstract]

Net Income per Common Share

Net Income per Common Share

Basic net income per common share is computed by dividing net income available to Thermon Group Holdings, Inc. by the weighted average number of common shares outstanding during each period. Diluted net income per common share is computed by dividing net income available to Thermon Group Holdings, Inc. by the weighted average number of common shares and common share equivalents outstanding (if dilutive) during each period. The number of common share equivalents, which includes options and both restricted and performance stock units, is computed using the treasury stock method. With regard to the performance stock units, we assume that the associated performance targets will be met at the target level of performance for purposes of calculating diluted net income per common share until such time that it is probable that the performance target will not be met.

The reconciliations of the denominators used to calculate basic net income per common share and diluted net income per common share for fiscal 2021, 2020, and 2019, respectively, is as follows:

	Year Ended March 31, 2021		Year Ended March 31, 2020		Year Ended March 31, 2019
Basic net income per common share
Net income available to Thermon Group Holdings, Inc.	$	1,165	$	11,938	$	22,756
Weighted-average common shares outstanding	33,134,592		32,760,327		32,568,541

Diluted net income per common share	$	0.03	$	0.36	$	0.69

For the year ended March 31, 2021, 2020, and 2019, 85,322, zero and zero equity awards, respectively, were not included in the calculation of diluted net income per common share since they would have had an anti-dilutive effect.

    We identified the prolonged economic effects of the COVID-19 pandemic to be an indicator of potential asset impairments in our reporting units. In the fourth quarter of fiscal 2021, we performed our annual goodwill and tangible impairment assessments including our indefinite life trademarks. We analyzed our reporting units utilizing the income approach, based on discounted future cash flows, which are derived from internal forecasts and economic expectations, and the market approach, based on market multiples of guideline public companies. The impairment test for indefinite life trademarks utilized a relief from royalty analysis based on the cash flow streams attributable to the Thermon trademark. Based on the goodwill and assets impairment assessment, the estimated fair value of our reporting units exceeded the carrying value. As such, there was no impairment of goodwill, assets or our indefinite life trademarks as of the respective reporting periods. The

most significant inputs in the Company's impairment test are the projected financial information, the weighted average cost of capital and market multiples for similar transactions. If the overall economic conditions, energy market or factors specific to the Company deteriorate further, it could negatively impact the Company's future impairment tests. We will continue to monitor our reporting unit's goodwill and asset valuations and test for potential impairments until the overall market conditions improve.

    Our total intangible assets at March 31, 2021, and 2020 consisted of the following:

Trademarks and certifications have indefinite lives. Developed technology, products, customer relationships and other intangible assets have estimated lives of 20 years, 10 years, 10 years and 6 years, respectively. The weighted average useful life for the group is 12 years. Customer relationships intangibles associated with THS, with a gross carrying amount of $11,438, have a useful life of 17 years. Intangible assets held in non-U.S. entities are valued in foreign currencies; accordingly changes in indefinite life intangible assets, such as certifications, at March 31, 2021 and 2020 were the result of foreign currency translation adjustments. Foreign currency translation adjustments also impacted finite life intangible assets held in non-U.S. entities.

Senior Secured Credit Facility

    On October 30, 2017, the Company, as a credit party and a guarantor, Thermon Holding Corp. (the “U.S. Borrower”) and Thermon Canada Inc. (the “Canadian Borrower”), as borrowers, entered into a credit agreement with several banks and other financial institutions or entities from time to time party thereto (the “Lenders”) and JPMorgan Chase Bank, N.A. as administrative agent (the “Agent”), which provides for a $250,000 seven-year term loan B facility made available to the U.S. Borrower and a $60,000 five-year senior secured revolving credit facility made available to the U.S. Borrower and the Canadian Borrower, which we refer to collectively as our “credit facility”. The proceeds of the term loan B were used to (1) pay in full $70,875 principal and interest on a previously issued term loan due April 2019; (2) repay $6,000 in unpaid principal and interest on the U.S. Borrower's revolving line of credit; (3) to fund approximately $201,900 CAD of the purchase price of the acquisition of THS and certain related real estate assets for approximately $164,900; and (4) pay certain transaction fees and expenses in connection with the THS acquisition and the credit facility.

    Interest rates and fees. The U.S. Borrower will have the option to pay interest on the term loan B facility at a base rate, plus an applicable margin, or at a rate based on LIBOR, (subject to a floor of 1.00%), plus an applicable margin. The applicable margin for base rate loans is 275 basis points and the applicable margin for LIBOR loans is 375 basis points. The end-user Borrower may borrow revolving loans in U.S. dollars and the Canadian Borrower may also borrow revolving loans in Canadian dollars. Borrowings under the revolving credit facility (a) made in U.S. dollars will bear interest at a rate equal to a base rate, plus an applicable margin of 225 basis points or at a rate based on LIBOR, plus an applicable margin of 325 basis points and (b) made in Canadian dollars will bear interest at a rate equal to a Canadian base rate, plus an applicable margin of 225 basis points or at a rate based on Canadian Dollar Offered Rate, plus an applicable margin of 325 basis points; provided, that since the completion of the fiscal quarter ended March 31, 2018, the applicable margins in each case will be determined based on a leverage-based performance grid, as set forth in the credit agreement. In addition to paying interest on outstanding principal under the revolving credit facility, the U.S. Borrower is required to pay a commitment fee in respect of any unutilized revolving commitments of 0.50% per annum based on a leverage-based performance grid.

    Maturity and repayment. The revolving credit facility terminates on October 28, 2022. The scheduled maturity date of the term loan facility is October 30, 2024. Commencing April 1, 2018, the term loan will amortize in equal quarterly installments of 0.25% of the $250,000 term loan, with the payment of the balance at maturity. The U.S. Borrower will be able to voluntarily prepay the principal of the term loan without penalty or premium (subject to breakage fees) at any time in whole or in part; provided that for the first six months after the October 30, 2017 closing date, the U.S. Borrower is required to pay a 1% premium for prepayments of the term loan with the proceeds of certain repricing transactions. The U.S. Borrower is required to repay the term loan with certain asset sale and insurance proceeds, certain debt proceeds and, commencing for the fiscal year ended March 31, 2019, 50% of excess cash flow (reducing to 25% if the Company’s leverage ratio is less than 4.0 to 1.0 but greater than or equal to 3.5 to 1.0 and 0% if the Company’s leverage ratio is less than 3.5 to 1.0). The remaining balance will be due at maturity of the term loan B facility on October 30, 2024.

    Accordion. The credit facility allows for incremental term loans and incremental revolving commitments in an amount not to exceed $30,000 and an unlimited additional amount that would not cause the consolidated secured leverage ratio to exceed 4.0 to 1.0 (or, if less, the maximum consolidated leverage ratio permitted by the revolving credit facility on such date).

    At March 31, 2021, we had no outstanding borrowings under our revolving credit facility for the Canadian Borrower line of credit or for the U.S. Borrower line of credit. As of March 31, 2021, we had $56,686 of available borrowing capacity under our revolving credit facility after taking into account the borrowing base, outstanding borrowings and letters of credit outstanding. The variable rate term loan bears interest at the LIBOR rate plus an applicable margin dictated by our leverage ratio (as described above). The interest rate on the variable rate term loan on March 31, 2021 was 4.75%.

    Guarantees; security. The term loan is guaranteed by the Company and all of the Company's current and future wholly-owned domestic material subsidiaries (the “U.S. Subsidiary Guarantors”), subject to certain exceptions. Obligations of the U.S. Borrower under the revolving credit facility are guaranteed by the Company and the U.S. Subsidiary Guarantors. The obligations of the Canadian Borrower under the revolving credit facility are guaranteed by the Company, the U.S. Borrower, the U.S. Subsidiary Guarantors and each of the wholly owned Canadian material subsidiaries of the Canadian Borrower, subject to certain exceptions. The term loan and the obligations of the U.S. Borrower under the revolving credit facility are secured by a first lien on all of the Company’s assets and the assets of the U.S. Subsidiary Guarantors, including 100% of the capital stock of the U.S. Subsidiary Guarantors and 65% of the capital stock of the first tier material foreign subsidiaries of the Company, the U.S. Borrower and the U.S. Subsidiary Guarantors, subject to certain exceptions. The obligations of the Canadian Borrower under the revolving credit facility are secured by a first lien on all of the Company's assets, the U.S. Subsidiary Guarantors' assets, the Canadian Borrower’s assets and the assets of the material Canadian subsidiaries of the Canadian Borrower, including 100% of the capital stock of the Canadian Borrower’s material Canadian subsidiaries.

Financial covenants. The term loan is not subject to any financial covenants. The revolving credit facility requires the Company, on a consolidated basis, to maintain certain financial covenant ratios. The Company must maintain a consolidated leverage ratio of 3.75:1.0 as measured on the last day of any fiscal quarter. In addition, on the last day of any period of four fiscal quarters, the Company must maintain a consolidated fixed charge coverage ratio of not less than 1.25:1.0. As of March 31, 2021, we were in compliance with all financial covenants of the credit facility.

Restrictive covenants.  The credit agreement governing our facility contains various restrictive covenants that, among other things, restrict or limit our ability to (subject to certain negotiated exceptions): incur additional indebtedness; grant liens; make fundamental changes; sell assets; make restricted payments including cash dividends to shareholders; enter into sales and leaseback transactions; make investments; prepay certain indebtedness; enter into transactions with affiliates; and enter into restrictive agreements.

Maturities of long-term debt principal payments are as follows for the fiscal years ended March 31:

2023	2,500
2024	2,500

Related-Party Transactions

Related-Party Transactions    In connection with the TPS transaction, one of the former TPS principals (the "TPS Minority Shareholder") retained 25% of the ownership of the entities holding the TPS business unit. During the fiscal year ended March 31, 2017, this

individual, together with the two other former principals of TPS, were paid $5,805 in the aggregate in full satisfaction of the Company's obligations under the $5,905 non-interest bearing performance-based note issued in connection with the TPS transaction.

    On April 2, 2018, the TPS Minority Shareholder provided the Company notice that he was exercising his option to sell one-half (12.5%) of his remaining equity interest in the entities holding the TPS business unit to the Company, and such sale was completed and effective as of July 20, 2018. The terms of the April 2015 TPS purchase agreement prescribed a valuation formula for such a sale based on TPS's financial results for the 12 months ended March 31, 2018. During the first quarter of the fiscal year ended March 31, 2019, the Company paid $5,665 to purchase the 12.5% non-controlling interest.

    Similarly, on April 2, 2019, the TPS Minority Shareholder provided the Company notice in order to exercise his option to sell the entirety of his remaining equity interest (12.5% of the entities holding the TPS business unit) to the Company. The terms of the April 2015 TPS purchase agreement prescribed a valuation formula for such a sale based on TPS’s financial results for the fiscal year ended March 31, 2019. The Company paid $4,508 to purchase the remaining 12.5% non-controlling interest on August 1, 2019.

Employee Benefits

Employee Benefits

The Company has defined contribution plans covering substantially all domestic employees and certain foreign subsidiary employees who meet certain service and eligibility requirements. Participant benefits are 100% vested upon participation. The Company matches employee contributions, limited to 50% of the first 6% of each employee's salary contributed. The Company's matching contributions to defined contribution plans on a consolidated basis were approximately $2,561, $2,607, and $2,315 in fiscal 2021, 2020, 2019, respectively.

The Company has an incentive compensation program to provide employees with incentive pay based on the Company's ability to achieve certain sales, profitability, and safety objectives. From time to time, the compensation committee of the Board of Directors, at its sole discretion, can add additional amounts to the overall incentive pay achieved. The Company recorded approximately $2,767, $3,104, and $9,885 for incentive compensation earned and other discretionary amounts in fiscal 2021, 2020, 2019, respectively.

    The Company provides a non-qualified deferred compensation plan for certain highly compensated employees where payroll contributions are made by the employees on a pre-tax basis. Included in “Other long-term assets” in the consolidated balance sheets at March 31, 2021 and 2020 were $5,047 and $2,849, respectively, of deferred compensation plan assets held by the Company. Deferred compensation plan assets (mutual funds) are measured at fair value on a recurring basis based on quoted market prices in active markets (Level 1). The Company has a corresponding liability to participants of $4,608 and $2,886 included in “Other long-term liabilities” in the consolidated balance sheet at March 31, 2021 and 2020, respectively.

Restructuring and Related Activities [Abstract]

Restructuring and other charges (income)

Restructuring and Other Charges/(income)

During fiscal 2021, we enacted certain restructuring initiatives to align our cost structure with the decline in demand for our products and services primarily due to COVID-19 and supply/demand fluctuations in commodity prices. Moreover, during fiscal 2021, the Company terminated approximately 252 people (both hourly and salaried positions) and incurred $5,748 in one-time severance costs. These charges were recorded to restructuring and other charges/(income) in our consolidated statements of operations and comprehensive income/(loss).

In addition, we incurred $429 in lease impairment costs primarily related to one of our Canadian facilities that was substantially vacated by December 31, 2020, as the Company executed efforts to optimize its global manufacturing footprint. We also exercised the early termination option for one of our existing leases in Canada, which resulted in the remeasurement of the related right-of-use asset and lease liability and accelerated the lease amortization and expense to align with the cease use date of the facility. We substantially vacated the facility by December 31, 2020. Finally, we early terminated one of our leases in our US-LAM segment. As a result of these abandonments, we recorded a total of $381 in lease abandonment charges during fiscal 2021. We recorded these charges to restructuring and other charges/(income) in our consolidated statements of operations and comprehensive income.

Disposal of South Africa Business

On December 15, 2020, a Sale of Shares Agreement was entered into between one of our consolidated subsidiaries and an investor consortium (the "TSAPL Purchasers"). As a result of this agreement, 100% of the outstanding common shares of our consolidated subsidiary, Thermon South Africa Proprietary Limited (the "South Africa Business"), were sold to the TSAPL Purchasers, with aggregate proceeds of 2,500 South African Rand (ZAR), or $167, as partial satisfaction of an existing note receivable. In addition, Purchasers committed to settle operational receivables attributable to other Company subsidiaries existing at the time of sale.

After evaluating our presence in the region served by the South Africa Business, the Company decided to centralize and consolidate our business structure and streamline our organization. A member of the TSAPL Purchasers was the current general manager of the operations of the South Africa business at the time of sale. This sale is accompanied by a distribution agreement whereby the new owners of the business have agreed to distribute our products, continuing the Company's presence in the region. We believe this is an opportunity to optimize the business while pivoting to a new relationship that will better enable us to serve our customers.

As a result of the sale and in accordance with Impairment and Disposal of Long-Lived Assets ("ASC 360"), we recognized a loss on the sale of a business of $2,065, which included the impact of a currency translation adjustment of $828. This loss was recognized within restructuring and other charges/(income) on the consolidated statements of operations and comprehensive income/(loss). The reported loss on sale of stock is not deductible for tax. Prior to the disposal, the South Africa Business's results were reported within the "Europe, Middle East and Africa" segment.

Restructuring and other charges/(income) by reportable segment were as follows:

	Year Ended March 31, 2021
United States and Latin America	$	3,563
Canada	2,591
Europe, Middle East and Africa	2,459
Asia-Pacific	10
	$	8,623

Restructuring activity related to severance activity described above recorded in "Accrued liabilities" on the condensed consolidated balance sheets is summarized as follows for fiscal 2021:

Beginning balance, April 1, 2020	$	—
Costs incurred	5,748
Less cash payments	(5,091)
Ending balance, March 31, 2021	$	657

We believe we are substantially complete with accruing costs related to restructuring activities as of the end of fiscal 2021.

Commitments and Contingencies

Commitments and Contingencies

At March 31, 2021, the Company had in place letter of credit guarantees and performance bonds securing performance obligations of the Company. These arrangements totaled approximately $6,905. Of this amount, $1,066 is secured by cash deposits at the Company's financial institutions and an additional $3,314 represents a reduction of the available amount of the Company's short term and long-term revolving lines of credit. Included in prepaid expenses and other current assets at March 31, 2021 and 2020, was approximately $1,667 and $2,769, respectively, of cash deposits pledged as collateral on performance bonds and letters of credit. Our Indian subsidiary also has $4,938 in customs bonds outstanding to secure the Company's customs and duties obligations in India.

    The Company has entered into information technology service agreements with several vendors. The service fees expense amounted to $1,768, $2,679, and $3,809 in fiscal 2021, 2020, 2019, respectively. The future annual service fees under the service agreements are as follows for the fiscal years ended March 31:

2022	$	1,087
2023	896
Total	$	1,983

We are involved in various legal and administrative proceedings that arise from time to time in the ordinary course of doing business. Some of these proceedings may result in fines, penalties or judgments being assessed against us, which may adversely affect our financial results. In addition, from time to time, we are involved in various disputes, which may or may not be settled prior to legal proceedings being instituted and which may result in losses in excess of accrued liabilities, if any, relating to such unresolved disputes. As of March 31, 2021, management believes that adequate reserves have been established for any probable and reasonably estimable losses. Expenses related to litigation reduce operating income. We do not believe that the outcome of any of these proceedings or disputes would have a significant adverse effect on our financial position, long-term results of operations, or cash flows. It is possible, however, that charges related to these matters could be significant to our results of operations or cash flows in any one reporting period. 

In addition to the legal proceedings described above, in January 2020, the Company received service of process in a class action application in the Superior Court of Quebec, Montreal, Canada related to certain heating elements previously manufactured by THS and incorporated into certain portable construction heaters sold by certain manufacturers. The Company believes this claim is without merit and intends to vigorously defend itself against the claim. While the Company continues to dispute the allegations, in March 2021, it reached an agreement in principle with the plaintiff and other defendants to resolve this matter without admitting to any liability; such agreement remains subject to the agreement of the parties on the terms of a definitive settlement agreement. Settlement of this matter on the agreed terms will require the Company to contribute an amount that would not have a material impact on the Company’s consolidated financial position, results of operations or cash flows. The settlement is subject to, among other things, approval by the Superior Court.

    As of March 31, 2021, the Company has accrued $4,380 as estimated additional cost related to the operational execution of a project in our US-LAM segment.

Share-based Payment Arrangement [Abstract]

Stock-Based Compensation Expense

Stock-Based Compensation Expense

The Board of Directors has adopted and the shareholders have approved three stock option award plans. The 2010 Thermon Group Holdings, Inc. Restricted Stock and Stock Option Plans ("2010 Plan") was approved on July 28, 2010. The plan authorized the issuance of 2,767,171 stock options or restricted shares (on a post stock split basis). On April 8, 2011, the Board of Directors approved the Thermon Group Holdings, Inc. 2011 Long-Term Incentive Plan ("2011 LTIP"). The 2011 LTIP made available 2,893,341 shares of the Company's common stock that may be awarded to employees, directors or non-employee contractor's compensation in the form of stock options or restricted stock awards. On May 21, 2020, the Board of Directors approved the Thermon Group Holdings, Inc. 2020 Long-Term Incentive Plan ("2020 LTIP"). The 2020 LTIP made available 1,400,000 shares of the Company's common stock that may be awarded to employees, directors, or non-employee contractor's compensation in the form of stock options or restricted stock awards. Collectively, the 2010 Plan, the 2011 LTIP, and the 2020 LTIP are referred to as the "Stock Plans." The Company does not hold any shares of its own stock as treasury shares. Accordingly, the vesting of restricted stock units and performance stock units and the exercise of stock options result in the issuance of additional new shares of the Company's stock.

Unvested options outstanding are scheduled to cliff vest over three years with 100% vesting on the third anniversary date of the grant. Stock options must be exercised within 10 years from date of grant. Stock options were issued with an exercise price which was equal to the market price of our common stock at the grant date. We account for forfeitures as they occur, rather than estimate expected forfeitures.

Stock Options

A summary of stock option activity under our Stock Plans for fiscal 2021, 2020, and 2019 are as follows:

		Options Outstanding

For fiscal 2021, 2020, and 2019 the intrinsic value of stock option exercises was $646, $3,240, and $555, respectively. During fiscal 2021, no options exercised will be transacted in the first quarter of fiscal year ending March 31, 2022.

For fiscal 2021, 2020, and 2019, we recorded stock-based compensation of $3,728, $4,960, and $4,148, respectively. As of March 31, 2021, there was no unrecognized expense related to unvested stock option awards.

The following table summarizes information about stock options outstanding as of March 31, 2021:

	Options Outstanding						Options Vested and Exercisable

    The aggregate intrinsic value in the preceding table represents the total intrinsic value based on our closing stock price of $19.49 as of March 31, 2021, which would have been received by the option holders had all option holders exercised as of that date.

    Stock options are valued by using a Black-Scholes-Merton option pricing model. We calculate the value of our stock option awards when they are granted. Accordingly, we update our valuation assumptions for volatility and the risk free interest rate each quarter that option grants are awarded. Annually, we prepare an analysis of the historical activity within our option plans as well as the demographic characteristics of the grantees of options within our stock option plan to determine the estimated life of the grants and possible ranges of estimated forfeiture. The expected life was determined using the simplified method for estimating expected option life, which qualify as "plain-vanilla" options. The risk-free interest rate is based on the rate of a zero-coupon U.S. Treasury instrument with a remaining term approximately equal to the expected term. We do not expect to pay dividends in the near term and therefore do not incorporate the dividend yield as part of our assumptions.

Restricted Stock Awards and Units

    Restricted stock awards have been issued to members of our board of directors and restricted stock units have been issued to certain employees. For restricted stock awards, the actual common shares have been issued with voting rights and are included as part of our total common shares outstanding. The common shares may not be sold or exchanged until the vesting period is completed. For restricted stock units, no common shares are issued until the vesting period is completed. For restricted stock units, the Company allows its employees to withhold a portion of their units upon the vesting dates in order to satisfy their tax obligation. For both restricted stock awards and units, fair value is determined by the market value of our common stock on the date of the grant.

    During fiscal 2015, we established a plan to issue our directors awards of fully vested common stock in lieu of restricted stock awards. During fiscal 2021 and fiscal 2020, we issued 52,098 and 26,608 fully vested common shares which had a total fair value of $712 and $660 based on the closing price of our common stock on the date of issuance, respectively. As of March 31, 2021, there were no outstanding restricted stock awards.

    The following table summarizes the activity with regard to unvested restricted stock units issued to employees during fiscal 2021, fiscal 2020, and fiscal 2019.

Based on our closing stock price of $19.49, the aggregate intrinsic value of the unvested restricted stock units at March 31, 2021 was $5,935. Total unrecognized expense related to unvested restricted stock awards was approximately $2,994 as of March 31, 2021. We anticipate this expense to be recognized over a weighted average period of approximately 1.8 years.

Performance Stock Units. During fiscal 2021, 2020, and 2019, performance stock unit awards were issued to our executive officers and other members of management and had total estimated grant date fair values of $1,947, $2,285 and $1,654, respectively. For the fiscal 2021 awards, the performance indicator for these awards is a combination of stock price and the Company's Adjusted EBITDA. The target number of shares is 49,716 and 86,634 for the stock price awards and Adjusted EBITDA awards, respectively. For those awards utilizing a stock price indicator, the stock price indicator measures our stock price relative to a predetermined peer group of companies with similar business characteristics as ours. Since the stock price indicator is market-based, we prepared a Monte Carlo valuation model to calculate the probable outcome of the market for our stock to arrive at the fair value. The fair value of the market based units will be expensed over three years, whether or not the market condition is met. For those awards utilizing an Adjusted EBITDA indicator, the Adjusted EBITDA indicator establishes the target Adjusted EBITDA for each of the three years ending March 31, 2023. Since these are performance based stock awards, the Company will make estimates of periodic expense until the Adjusted EBITDA target is known and the expense for actual number of shares earned is determinable.

During fiscal 2021 and 2020, certain Adjusted EBITDA-based performance stock awards that were scheduled to vest did not meet the minimum Adjusted EBITDA indicator. Accordingly, 130,835 and 5,153 of previously outstanding performance stock units were forfeited during fiscal 2021 and 2020, respectively. For performance stock units, the performance period will end on the third fiscal year end subsequent to the award being granted. It will then be determined how many shares of stock will be issued. In each year of the performance period, the possible number of shares will range from zero percent to two hundred percent of the target shares.

    The following table summarized the target number of performance stock units outstanding and the minimum and maximum number of shares that can be earned as of March 31, 2021.     

Fiscal Year Granted	Target	Minimum	Maximum
Fiscal 2019	68,178	0	136,356
Fiscal 2020	92,394	0	184,788
Fiscal 2021	136,350	0	272,700

    In fiscal 2021, 2020 and 2019, the performance objectives for 4,476, 79,144 and 36,611 awards, respectively, were earned.

    At March 31, 2021, there was $1,461 in stock compensation that remained to be expensed, which will be recognized over a period of 1.5 years.

The Company expects that it is more likely than not that the results of future operations will generate sufficient taxable income to realize its domestic and foreign deferred tax assets, net of valuation allowance reserves.

    The U.S. and non-U.S. components of income (loss) from continuing operations before income taxes were as follows:

	Year Ended March 31, 2021		Year Ended March 31, 2020		Year Ended March 31, 2019

    On December 22, 2017, the United States enacted significant changes to U.S. tax law following the passage and signing of H.R.1, “An Act to Provide for Reconciliation Pursuant to Titles II and V of the Concurrent Resolution on the Budget for fiscal Year 2018” (the “Tax Act”) (previously known as “The Tax Cuts and Jobs Act”).  The Tax Act included significant changes to existing tax law, including a permanent reduction to the U.S. federal corporate income tax rate from 35% to 21%, a one-time repatriation tax on deferred foreign income (“Transition Tax”), deductions, credits and business-related exclusions. 

    Consistent with provisions allowed under the Tax Act, the net $4,007 calculated Transition Tax liability will be paid over an eight year period beginning in fiscal year 2019. At March 31, 2020, $2,478 of the Transition Tax liability is included in “Other liabilities- long-term” in the consolidated balance sheets.  

    The net benefit of $3,097 related to deferred tax assets and liabilities is primarily associated with a reduction in deferred liabilities for unamortized intangible assets. Since these intangible assets are not tax deductible, the reduction of the liability is non-cash and will not reduce future tax payments.

Given the Tax Act’s significant changes and the opportunities to repatriate cash tax free, we have reevaluated our current permanent reinvestment position. Accordingly, we no longer assert a permanent reinvestment position in most of our foreign subsidiaries. We expect to repatriate certain earnings which will be subject to withholding taxes.  At March 31, 2021 we have accrued $1,073 as an additional deferred tax liability associated with the future repatriation of earnings from jurisdictions that withhold taxes on foreign paid dividends.  

    While the Tax Act provides for a modified territorial tax system, beginning in January 1, 2018, global intangible low-taxed income, or ("GILTI"), provisions will be applied by the United States providing an incremental tax on certain foreign income. The GILTI provisions require the Company to include in its U.S. income tax return foreign subsidiary earnings in excess of an allowable return on the foreign subsidiary's tangible assets. Under GAAP, the Company is allowed to make an accounting policy choice of either (1) treating taxes due on the future U.S. inclusions in taxable income related to GILTI provisions as a current-period expense when incurred, or the period cost method, or (2) factoring such amounts into the Company's measurement of its deferred taxes, or the deferred method. The Company has selected the period cost method as its accounting policy with respect to the new GILTI tax rules.

    To provide relief for taxpayers impacted by the COVID-19 outbreak, the United States enacted the Coronavirus Aid, Relief, and Economic Security (CARES) Act on March 27, 2020. Among other provisions, the law provides relief to U.S. federal corporate taxpayers through temporary adjustments to net operating loss rules, changes to interest expense deductibility, and enhanced qualified improvement property depreciation. Under ASC 740, the Company recognized the effect of the change in tax law on existing deferred tax assets and liabilities in income from continuing operations in the interim period that includes March 27, 2020. The primary impact to the Company for CARES was our ability to fully deduct interest expense for the twelve months ended March 31, 2020.

During the year ended March 31, 2021, the Company recorded discrete tax benefits of $1,859 related to updated Internal Revenue Service rules regarding the United States Global intangible low-taxed income or ("GILTI tax") and related tax planning elections associated with the GILTI tax rule changes. Under the new rules, Thermon was able to reduce previously incurred GILTI tax under the high tax exception rules. Included with this benefit are certain tax elections that resulted in the reduction of previous tax expense.

During the year ended March 31, 2021, the Company incurred a taxable loss within its operations in the United States. As a result, the net operating loss was available to be carried back to the Company's 2016 tax year when the federal tax rate was 35%. The rate differential resulted in a discrete tax benefit of $1,470.

The loss on the capital stock sale of the South Africa Business, referred to in Note 14, "Restructuring and other charges/(income)," was not deductible for income tax. This resulted in approximately $526 of discrete tax expense during the fiscal 2021.

During the twelve months ended March 31, 2020, the Company recorded the impact of a prospective income tax rate reduction in the tax jurisdictions of Alberta, Canada and the Netherlands. The scheduled rate reductions of 4% and 3%, respectively, resulted in a net reduction of deferred tax liabilities of $1,231 reported as a benefit to tax expense. In fiscal 2021, the Netherlands reversed their prospective tax reduction. Accordingly, the Company adjusted its deferred tax liability resulting in additional tax expense $332.

    As of March 31, 2021, the Company had foreign tax net operating loss carry-forwards ("NOLs") of $4,421. Of this amount, $1,320 may be carried forward indefinitely. As of March 31, 2021, the tax years 2017 through 2020 remain open to examination by the major taxing jurisdictions to which we are subject.

    At March 31, 2020, reserves for uncertain tax position consisted of uncertain tax positions related to the final Transition Tax that we determined could be overturned if the calculations were examined by tax authorities. The reserves for the Transition Tax will remain subject to examination until January 2025. No reserves are expected to be released within twelve months. Activity within our reserve for uncertain tax positions as well as the penalties and interest are recorded as a component of the Company's income tax expense. A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows:

	Year Ended March 31, 2021		Year Ended March 31, 2020
Beginning balance	$	729	$	1,137
Release of reserve	—		(463)
Interest and penalties on prior reserves	79		55
Reserve for uncertain income taxes	$	808	$	729

Segment Information

Segment Information

    We operate in four reportable segments based on four geographic countries or regions in which we operate: (i) United States and Latin America ("US-LAM"), (ii) Canada, (iii) Europe, Middle East and Africa ("EMEA") and (iv) Asia-Pacific ("APAC"). Within our four reportable segments, our core products and services are focused on thermal solutions primarily related to the electrical heat tracing industry. Each of our reportable segments serves a similar class of customers, including engineering, procurement and construction companies, international and regional oil and gas companies, commercial sub-contractors, electrical component distributors and direct sales to existing plant or industrial applications. Profitability within our segments is measured by operating income. Profitability can vary in each of our reportable segments based on the competitive environment within the region, the level of corporate overhead, such as the salaries of our senior executives, and the level of research and development and marketing activities in the region, as well as the mix of products and services. For purposes of this note, revenue is attributed to individual countries or regions on the basis of the physical location and jurisdiction of organization of the subsidiary that invoices the material and services.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Consolidation

Basis of ConsolidationThe consolidated financial statements include the accounts of the Company, its subsidiaries and entities in which the Company has a controlling financial interest. The ownership of non-controlling investors is recorded as non-controlling interests. All significant inter-company balances and transactions have been eliminated in consolidation.

Segment Reporting

Segment Reporting

We maintain four reportable segments based on the four geographic countries or regions in which we operate: (i) United States and Latin America ("US-LAM"), (ii) Canada, (iii) Europe, Middle East and Africa ("EMEA") and (iv) Asia-Pacific ("APAC"). Profitability within our segments is measured by operating income. See Note 19, "Segment Information" for financial data relating to our four reportable geographic segments.

Use of Estimates

Use of Estimates

The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results inevitably will differ from those estimates, and such differences may be material to the financial statements.

Cash Equivalents

Cash Equivalents

Cash and cash equivalents consist of cash in bank and money market funds. All highly liquid investments purchased with original maturities of three months or less are considered to be cash equivalents.

Restricted Cash

    The Company maintains restricted cash related to certain letter of credit guarantees and performance bonds securing performance obligations. The following table provides a reconciliation of cash, cash equivalents, restricted cash included in prepaid expenses and other current assets and restricted cash included in other long-term assets reported within the statement of financial position that sum to the total of the same such amounts shown in the statement of cash flows.

	March 31, 2021		March 31, 2020		March 31, 2019
Cash and cash equivalents	$	40,124	$	43,237	$	31,402
Restricted cash included in prepaid expenses and other current assets	1,962		2,421		1,624
Restricted cash included in other long-term assets	364		348		815
Total cash, cash equivalents, and restricted cash shown in the statement of cash flows	$	42,450	$	46,006	$	33,841

    Amounts shown in restricted cash included in prepaid expenses and other current assets and other long-term assets represent those required to be set aside by a contractual agreement, which contain cash deposits pledged as collateral on performance bonds and letters of credit. Amounts shown in restricted cash in other long-term assets represent such agreements that require a commitment term longer than one year.

Receivables

Receivables

The Company's receivables are recorded at cost when earned and represent claims against third parties that will be settled in cash. The carrying value of the Company's receivables, net of allowance for doubtful accounts, represents its estimated net realizable value. If events or changes in circumstances indicate specific receivable balances may be impaired, further consideration is given to the Company's ability to collect those balances and the allowance is adjusted accordingly. The Company has established an allowance for doubtful accounts based upon an analysis of aged receivables. Past-due receivable balances are written-off when the Company's internal collection efforts have been unsuccessful in collecting the amounts due.

The Company's primary base of customers operates in the chemical and petrochemical, oil and gas, power generation, rail and transit, and other industries; we are diversifying our customer base through numerous other end markets. Although the Company has a concentration of credit risk within these industries, the Company has not experienced significant collection losses on sales to these customers. The Company's foreign receivables are not concentrated within any one geographic segment nor are they subject to any current economic conditions that would subject the Company to unusual risk. The Company does not generally require collateral or other security from customers.

The Company performs credit evaluations of new customers and sometimes requires deposits, prepayments or use of trade letters of credit to mitigate our credit risk.

Inventories

Inventories

Inventories, principally raw materials and finished goods, are valued at the lower of cost (weighted average cost) or net realizable value. We write down our inventory for estimated excess or obsolete inventory equal to the difference between the cost of inventory and estimated fair market value based on assumptions of future demand and market conditions. Fair market value is determined quarterly by comparing inventory levels of individual products and components to historical usage rates, current backlog and estimated future sales and by analyzing the age and potential applications of inventory, in order to identify specific products and components of inventory that are judged unlikely to be sold. Our finished goods inventory consists primarily of completed electrical cable that has been manufactured for various heat tracing solutions, as well as various types of immersion, circulation and space heaters for THS. Most of our manufactured product offerings are built to industry standard specifications that have general purpose applications and therefore are sold to a variety of customers in various industries. Some of our products, such as custom orders and ancillary components outsourced from third-party manufacturers, have more specific applications and therefore may be at a higher risk of inventory obsolescence. Inventory is written-off in the period in which the disposal occurs. Actual future write-offs of inventory may differ from estimates and calculations used to determine valuation allowances due to changes in customer demand, customer negotiations, product application, technology shifts and other factors. Historically, inventory obsolescence and potential excess cost adjustments have been within our expectations, and management does not believe that there is a reasonable likelihood that there will be a material change in future estimates or assumptions used to calculate the inventory valuation reserves.

Revenue Recognition

Revenue Recognition

Effective April 1, 2018, we adopted Accounting Standards Codification Topic 606, Revenue from Contracts with Customers ("ASC 606") using the modified retrospective method and applying ASC 606 to all revenue contracts with customers which were not completed as of the date of adoption. In accordance with the modified retrospective approach, prior period amounts were not adjusted. We expect the impact of the adoption of the new standard to continue to be immaterial to revenues and net income on an ongoing basis. Please refer to Note 4 "Revenue from Contracts with Customers" for additional information.

Property, Plant and Equipment

Property, Plant and EquipmentProperty, plant and equipment are stated at cost. Expenditures for renewals and improvements that significantly extend the useful life of an asset are capitalized. Expenditures for maintenance and repairs of assets are charged to operations as incurred. When assets are sold or retired, the cost and accumulated depreciation are removed from the accounts and any gain or loss is credited or charged to operations.

Goodwill and Other Intangible Assets

Goodwill and Other Intangible Assets

    We conduct a required annual review of goodwill for potential impairment in the fourth quarter, or sooner if events or changes in circumstances indicate that the fair value of a reporting unit is below its carrying value. Our reporting units are our operating segments: US-LAM, Canada, EMEA, and APAC. We have the option to perform a qualitative assessment to satisfy the annual test requirement if we believe that it is more likely than not that we do not have an impairment in any one of our reporting units. If the carrying value of a reporting unit that includes goodwill exceeds its fair value, which is determined using both the income approach and market approach, goodwill is considered impaired. The income approach determines fair value based on discounted cash flow model derived from a reporting unit’s long-term forecasted cash flows. The market approach determines fair value based on the application of earnings multiples of comparable companies to projected earnings of the reporting unit. The amount of impairment loss is measured as the difference between the carrying value and the fair value of a reporting unit but is limited to the total amount of goodwill allocated to the reporting unit. In performing the fair value analysis,

management makes various judgments, estimates and assumptions, the most significant of which is the assumption related to revenue growth rates.

The factors we considered in developing our estimates and projections for cash flows include, but are not limited to, the following: (i) macroeconomic conditions; (ii) industry and market considerations; (iii) costs, such as increases in raw materials, labor, or other costs; (iv) our overall financial performance; and, (v) other relevant entity-specific events that impact our reporting units. The determination of whether goodwill is impaired involves a significant level of judgment in the assumptions underlying the approach used to determine the estimated fair values of our reporting units. We believe that the estimates and assumptions used in our impairment assessment are reasonable; however, these assumptions are judgmental and variations in any assumptions could result in materially different calculations of fair value. We will continue to evaluate goodwill on an annual basis in our fourth quarter, and whenever events or changes in circumstances, such as significant adverse changes in operating results, market conditions, or changes in management’s business strategy indicate that there may be a probable indicator of impairment. It is possible that the assumptions used by management related to the evaluation may change or that actual results may vary significantly from management’s estimates. In fiscal 2021, 2020 and 2019, the Company determined that no impairment of goodwill existed.

Other intangible assets include indefinite lived intangible assets for which we must also perform an annual test of impairment. The Company's indefinite lived intangible assets consist primarily of trademarks. The fair value of the Company's trademarks is calculated using a "relief from royalty payments" methodology. This approach involves first estimating reasonable royalty rates for each trademark then applying these royalty rates to a net sales stream and discounting the resulting cash flows to determine the fair value. The royalty rate is estimated using both a market and income approach. The market approach relies on the existence of identifiable transactions in the marketplace involving the licensing of trademarks similar to those owned by the Company. The income approach uses a projected pretax profitability rate relevant to the licensed income stream. We believe the use of multiple valuation techniques results in a more accurate indicator of the fair value of each trademark. This fair value is then compared with the carrying value of each trademark. The results of this test during the fourth quarter of our fiscal year indicated that there was no impairment of our indefinite life intangible assets during fiscal 2021, 2020 and 2019.

Debt Issuance Costs

The Company capitalizes and defers the costs associated with establishing our debt and financing arrangements. These costs are amortized as interest expense over the life of the loan or related financing. Additionally, for any unscheduled principal payments the Company will record incremental deferred debt charges on a pro rata basis of the unamortized deferred debt balance at the time of the repayment. When debt or the contract is retired prematurely, the proportionate unamortized deferred issuance costs are expensed as loss on retirement. Deferred debt issuance costs expensed as part of interest expense for fiscal 2021, 2020 and 2019 were $1,525, $1,885 and $1,756, respectively.

Long-Lived Assets

Long-Lived AssetsThe Company evaluates its long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of these assets is measured by comparison of the carrying amounts to the future undiscounted cash flows that the assets are expected to generate. If the long-lived assets are considered impaired, the impairment to be recognized equals the amount by which the carrying value of the asset exceeds the estimated fair value and is recorded in the period the determination was made.

Stock-based Compensation

Stock-based Compensation

We account for share-based payments to employees in accordance with ASC 718, Compensation-Stock Compensation, which requires that share-based payments (to the extent they are compensatory) be recognized in our consolidated statements of operations and comprehensive income/(loss) based on their fair values.

As required by ASC 718, we recognize stock-based compensation expense for share-based payments that are expected to vest. In determining whether an award is expected to vest, we account for forfeitures as they occur, rather than estimate expected forfeitures.

We are also required to determine the fair value of stock-based awards at the grant date. For option awards that are subject to service conditions and/or performance conditions, we estimate the fair values of employee stock options using a Black-Scholes-Merton valuation model. Some of our option grants and awards included a market condition for which we used a

Monte Carlo pricing model to establish grant date fair value. These determinations require judgment, including estimating expected volatility. If actual results differ significantly from these estimates, stock-based compensation expense and our results of operations could be impacted.

Income Taxes

Income Taxes

We account for income taxes under the asset and liability method that requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been recognized in our financial statements or tax returns. Judgment is required in assessing the future tax consequences of events that have been recognized in our financial statements or tax returns. Variations in the actual outcome of these future tax consequences could materially impact our financial position, results of operations or effective tax rate.

Significant judgment is required in determining our worldwide income tax provision. In the ordinary course of a global business, there are many transactions and calculations where the ultimate tax outcome is uncertain. Some of these uncertainties arise as a consequence of revenue sharing and cost reimbursement arrangements among related entities, the process of identifying items of revenue and expense that qualify for preferential tax treatment, and segregation of foreign and domestic earnings and expenses to avoid double taxation. Although we believe that our estimates are reasonable, the final tax outcome of these matters could be different from that which is reflected in our historical income tax provisions and accruals. Such differences could have a material effect on our income tax provision and net income in the period in which such determination is made.

    In estimating future tax consequences, all expected future events are considered other than enactments of changes in tax laws or rates. Valuation allowances are established when necessary to reduce deferred tax assets to amounts which are more likely than not to be realized. We consider future growth, forecasted earnings, future taxable income, the mix of earnings in the jurisdictions in which we operate, historical earnings, taxable income in prior years, if carryback is permitted under the law, and prudent and feasible tax planning strategies in determining the need for a valuation allowance. In the event we were to determine that we would not be able to realize all or part of our net deferred tax assets in the future, an adjustment to the deferred tax assets valuation allowance would be charged to earnings in the period in which we make such a determination, or goodwill would be adjusted at our final determination of the valuation allowance related to an acquisition within the measurement period. If we later determine that it is more likely than not that the net deferred tax assets would be realized, we would reverse the applicable portion of the previously provided valuation allowance as an adjustment to earnings at such time. The amount of income tax we pay is subject to ongoing audits by federal, state and foreign tax authorities, which often result in proposed assessments. Our estimate of the potential outcome for any uncertain tax issue is highly judgmental. We account for these uncertain tax issues pursuant to ASC 740, Income Taxes, which contains a two-step approach to recognizing and measuring uncertain tax positions taken or expected to be taken in a tax return. The first step is to determine if the weight of available evidence indicates that it is more likely than not that the tax position will be sustained on audit, including resolution of any related appeals or litigation processes. The second step is to measure the tax benefit as the largest amount that is more than 50% likely to be realized upon ultimate settlement. Although we believe we have adequately reserved for our uncertain tax positions, no assurance can be given with respect to the final outcome of these matters. We adjust reserves for our uncertain tax positions due to changing facts and circumstances, such as the closing of a tax audit, judicial rulings, refinement of estimates or realization of earnings or deductions that differ from our estimates. To the extent that the final outcome of these matters is different than the amounts recorded, such differences generally will impact our provision for income taxes in the period in which such a determination is made. Our provisions for income taxes include the impact of reserve provisions and changes to reserves that are considered appropriate and also include the related interest and penalties.

During fiscal 2018, we revised our permanent reinvestment position whereby we expect to repatriate future earnings. Given the significant changes and potential opportunities to repatriate cash tax free due to H.R.1, “An Act to Provide for Reconciliation Pursuant to Titles II and V of the Concurrent Resolution on the Budget for fiscal Year 2018” (the “Tax Act”), we have reevaluated our current permanent reinvestment position. Accordingly, we will no longer assert a permanent reinvestment position in most of our foreign subsidiaries. We expect to repatriate certain earnings which will be subject to withholding taxes.  These additional withholding taxes are being recorded as an additional deferred tax liability associated with the basis difference in such jurisdictions. Please see Note 18, "Income Taxes" for more information on the impacts of the Tax Act.

Foreign Currency Transactions and Translation

Foreign Currency Transactions and Translation

Exchange rate gains and losses that result from foreign currency transactions are recognized in income as they are realized. For the Company's non-U.S. dollar functional currency subsidiaries, assets and liabilities of foreign subsidiaries are translated into U.S. dollars using year-end exchange rates. Income and expense items are translated at weighted average

exchange rates prevailing during the year. Adjustments resulting from translation of financial statements are reflected as a separate component of shareholders' equity.

Loss Contingencies

Loss Contingencies

We accrue for probable losses from contingencies on an undiscounted basis, when such costs are considered probable of being incurred and are reasonably estimable. Legal expense related to such matters are expensed as incurred. We periodically evaluate available information, both internal and external, relative to such contingencies and adjust this accrual as necessary. Disclosure of a contingency is required if there is at least a reasonable possibility that a material loss has been incurred. In determining whether a loss should be accrued we evaluate, among other factors, the degree of probability of an unfavorable outcome and the ability to make a reasonable estimate of the amount of loss.

Warranties

Warranties

The Company offers a standard warranty on product sales. Specifically, we will replace any defective product within one year from the date of purchase. Warranties on construction projects are negotiated individually, are typically one year in duration, and may include the cost of labor to replace products. Factors that affect the Company's warranty liability include the amount of sales, historical and anticipated rates of warranty claims, and cost per claim. The Company periodically assesses the adequacy of its recorded warranty liabilities and adjusts the amounts as necessary.

Research and Development

Research and DevelopmentResearch and development expenditures are expensed when incurred and are included in marketing, general, administrative, and engineering expenses. Research and development expenses include salaries, direct material costs incurred, plus building and other overhead expenses.

Shipping and Handling Cost

Shipping and Handling Cost

The Company includes shipping and handling as part of cost of sales and freight due from customers is included as part of sales.

Economic Dependence

Economic DependenceAs of March 31, 2021 and 2020, no one customer represented more than 10% of the Company's accounts receivable balance. In fiscal 2021 and 2020,

Recent Accounting Pronouncements

Recent Accounting Pronouncements

    Leases- In February 2016, the FASB issued Accounting Standard Update 2016-02 Leases (“ASC 842”), which provides guidance on the recognition, measurement, presentation and disclosure on leases. Under the standard, substantially all leases will be reported on the balance sheet as right-of-use assets and lease liabilities. The new guidance is effective for fiscal years and interim periods within those fiscal years beginning after December 15, 2018. The Company adopted the amended guidance using the modified retrospective method as of April 1, 2019. Please refer to Note 3 "Leases" for further discussion, including the impact the adoption had on our consolidated financial statements.

    Financial Instruments- In June 2016, the FASB issued Accounting Standards Update 2016-13 Financial Instruments- Credit Losses (“ASC 326”), which amends the guidance on the impairment of financial instruments. The standard adds an impairment model, referred to as current expected credit loss, which is based on expected losses rather than incurred losses. The standard applies to most debt instruments, trade receivables, lease receivables, reinsurance receivables, financial guarantees and loan commitments. Under the guidance, companies are required to disclose credit quality indicators disaggregated by year of origination for a five-year period. The new guidance is effective for fiscal years and interim periods within those fiscal years beginning after December 15, 2019. We adopted this standard effective April 1, 2020, and such adoption did not have a material impact on our consolidated financial statements.

    Intangibles- In January 2017, the FASB issued Accounting Standards Update 2017-04 Intangibles- Goodwill and Other (“ASC 350”), which amends and simplifies the accounting for goodwill impairment by eliminating step 2 of the goodwill impairment test. Under the amended guidance, goodwill impairment will be measured as the excess of the reporting unit’s carrying value over its fair value, not to exceed the carrying amount of goodwill for that reporting unit. The changes are

effective for annual and interim periods beginning after December 15, 2019, and amendments should be applied prospectively. Early adoption is permitted for any impairment tests performed after January 1, 2017. We adopted this standard effective April 1, 2020, and such adoption did not have a material impact on our consolidated financial statements.

Reference Rate Reform- In March 2020, the FASB issued Accounting Standards Update 2020-04- Reference Rate Reform ("ASC 848"). The update is intended to provide temporary optional expedients and exceptions to the GAAP guidance on contract modifications and hedge accounting to ease the financial reporting burdens related to the expected market transition from the London Interbank Offered Rate (LIBOR) and other interbank offered rates to alternative reference rates. As of March 31, 2021, we have not yet elected any optional expedients provided in the standard. We will apply the accounting relief, if necessary, as relevant contract and hedge accounting relationship modifications are made during the reference rate reform transition period. We have adopted this standard effective April 1, 2020, and such adoption did not have a material impact on our consolidated financial statements.

Income Taxes- In December 2019, the FASB issued Accounting Standards Update 2019-12- Income Taxes ("ASC 740"). This ASU amends ASC 740 to add, remove, and clarify disclosure requirements related to income taxes. The new standard is effective for fiscal years beginning after December 15, 2020. We are still evaluating the impact of this new standard.
