Transforming the NDT Industry
Dr. Vahaviolos revolutionized the asset protection industry, leaving a lasting 
impact on industrial safety:
	 Pioneered Acoustic Emission (AE) technology, establishing AE as a 
	
standard method within the NDT community, which enabled MISTRAS to 
	
achieve a leading global market share.
	 Championed industry-wide advancements by serving as President of the 
	
American Society for Nondestructive Testing (ASNT) and playing a key role 
	
in international NDT standardization.
	 Earned prestigious recognitions, including being Lifetime Fellow of ASNT, 
	
IEEE, and AEWG, and receiving recognitions for individual accomplishments 
	
and lifetime contributions as an acoustic emission researcher

Shareholder Letter
Dear Shareholders,
2024 was a year of forward momentum for MISTRAS. We 
entered the year determined to build upon prior cost-saving 
and growth-oriented initiatives, and we exited it with a 
stronger balance sheet, improved operating leverage, and 
renewed clarity in our strategic vision.
In addition to further refining our cost structure to drive 
meaningful growth in adjusted EBITDA, our emphasis on 
disciplined execution resulted in revenue gains across all 
reported segments and industries served. This balance 
between rising top-line performance and continued expense 
calibration underscores our ongoing commitment to delivering 
value to all of our stakeholders.
These achievements speak to an organization 
that is both agile and deeply committed to the 
industries we serve. In every decision, we 
have remained centered on delivering the 
highest-quality asset protection solutions 
while creating a robust foundation for 
sustained profitability. This culture of 
adaptability and operational excellence 
has led to new efficiencies and strategic 
opportunities, ensuring that we are poised to 
unlock even greater value for customers and 
shareholders alike.
Financial Highlights of 2024
In 2024, MISTRAS achieved $729.6 million in consolidated 
revenue—an increase of 3.4% compared to the prior year. 
Simultaneously, our adjusted EBITDA rose by more than 25% 
to $82.5 million, underscoring the positive impact of optimized 
cost structures and operating leverage.
Our continued focus on disciplined execution was also evident 
in the Company’s $39.8 million in operating income, marking 
the highest level since 2016. Net income for 2024 was $19 
million, or $0.60 per diluted share. On a non-GAAP basis, net 
income rose to $22.7 million, equivalent to $0.72 per diluted 
share—our highest adjusted EPS in nearly a decade. During the 
year, we also intensified our efforts to pay down gross debt 
and streamline working capital, resulting in the strongest pace 
of free cash flow generation we have seen in several years.
Honoring our Founder & Chairman Emeritus
We want to honor the life and legacy of our Founder and 
Chairman Emeritus, Dr. Sotirios J. Vahaviolos, who passed 
away in early 2025. A visionary leader and pioneer in the 
field of non-destructive testing and acoustic emission, Dr. 
Vahaviolos founded MISTRAS (originally Physical Acoustics 
Corporation) in 1978, and dedicated over four decades 
to building the Company into a global leader in testing, 
inspection, and asset protection solutions. His expertise, 
leadership, and commitment to excellence were instrumental 
in shaping the Company’s strategic direction and fostering 
a culture of innovation that remains at the core of 
MISTRAS today. His legacy will continue to shape 
MISTRAS as we move forward in his memory.
An Invigorated Leadership Team
We announced a significant transition 
in our leadership, with Natalia Shuman 
joining MISTRAS as President, Chief 
Executive Officer and member of our Board 
of Directors following a deliberate, rigorous 
search. Natalia brings over two decades of 
leadership experience to MISTRAS, including 
executive management positions within the Testing, 
Inspection, and Certification (TIC) industry. Natalia has a 
proven track record of success, from driving transformative 
growth and developing high-performing teams to leading 
organizations through pivotal periods of change. 
As Executive Chairman, Manny Stamatakis will remain 
involved in overseeing the strategic path forward to maximize 
shareholder value and to support the new invigorated senior 
leadership team. With the full backing of Manny and the 
entire Board of Directors, we firmly believe Natalia’s fresh 
perspective and deep industry experience will drive MISTRAS’ 
continued evolution and keep us on the path of robust, 
profitable growth.
“Our emphasis
on disciplined execution 
resulted in revenue gains 
across all reported 
segments and 
end markets served.”

OUR BUSINESS 
 
Overview 
Mistras Group, Inc. is a leading "one source" multinational provider of integrated technology-enabled asset integrity solutions, 
helping to maximize the safety and operational uptime for civilization’s most critical industrial and civil assets. 
 
Backed by an innovative, data-driven asset protection portfolio, proprietary technologies, and a decades-long legacy of industry 
leadership, the Company helps customers with asset-intensive and mission critical infrastructure in the oil and gas, 
petrochemical, aerospace and defense, industrials, power generation and transmission (including alternative and renewable 
energy), other process industries and infrastructure, research and engineering and other industries towards achieving and 
maintaining operational excellence. By supporting these customers that help fuel our vehicles and power our society; inspecting 
components that are trusted for commercial, defense, and private space; and building monitoring equipment to help avoid 
catastrophic incidents, the Company helps the world at large with its asset integrity risk mitigation. 
 
The Company enhances value for its customers by integrating asset integrity protection throughout supply chains and 
centralizing integrity data through a suite of Industrial Internet of Things ("IoT")-connected digital software and monitoring 
solutions, including OneSuite™, which serves as an ecosystem platform, pulling together all of the Company’s software and 
data services capabilities, for the benefit of its customers. The Company’s core capabilities also include non-destructive testing 
("NDT") field inspections enhanced by advanced robotics, laboratory quality control, laboratory materials services, in-house 
laboratory assurance testing, sensing technologies and NDT equipment, asset and mechanical integrity engineering services, 
and light mechanical maintenance and access services.

Given the role our solutions play in enhancing the safe and efficient operation of our customers' infrastructure, we have 
historically provided a majority of our solutions to our customers on a regular, recurring basis. We perform these services 
largely at our customers’ facilities, while primarily servicing our aerospace customers at our network of state-of-the-art, in-
house laboratories. These solutions typically include NDT and inspection services, and can also include a wide range of 
mechanical services, including heat tracing, pre-inspection insulation stripping, coating applications, re-insulation, engineering 
assessments and long-term condition-monitoring.  
 
Under our business model, many customers outsource their inspection to us on a “run and maintain” basis. We have established 
long-term relationships as a critical solutions provider to many of the leading companies with asset-intensive infrastructure in 
our target markets. These markets include companies in the oil and gas, aerospace and defense, industrials, power generation 
and transmission (including alternative and renewable energy), other process industries and infrastructure, research and 
engineering and other industries. 
 
We have focused on providing our advanced asset protection solutions to our customers using proprietary, technology-enabled 
software and testing instruments, including those developed by our Products and Systems segment. In the past, we have made 
numerous acquisitions in an effort to grow our base of experienced, certified personnel, expand our service lines and technical 
capabilities, increase our geographical reach, complement our existing offerings, and leverage our fixed costs. We have 
increased our capabilities and the size of our customer base through the development of applied technologies and managed 
support services, organic growth and the integration of acquired companies. These acquisitions have provided us with 
additional service offerings, technologies, resources and customers, which we believe will enhance our advantages over our 
competition. 
 
We believe long-term growth can be realized in our target markets. Our business and financial results are impacted by world-
wide macro- and micro-economic conditions generally, as well as those within our target markets. Among other things, we 
expect the timing of our oil and gas customers inspection and maintenance expenditures to be impacted by oil price 
fluctuations.  
 
We have continued providing our customers with an innovative asset protection software ecosystem through our MISTRAS 
OneSuite platform. The OneSuite platform offers functions of MISTRAS' software and services brands as integrated 
applications on a cloud environment. OneSuite serves as a single access portal for customers' data activities and provides access 
to 90 plus applications being offered on one centralized platform.  
 
We have established long-term relationships as a critical solutions provider to many of the leading companies with asset-
intensive and mission-critical infrastructure in our target markets. These markets primarily consist of: 
• 
Oil and Gas (Downstream, Midstream and Upstream) 
• 
Aerospace and Defense 
• 
Industrial 
• 
Power Generation and Transmission 
• 
Infrastructure, Research and Engineering 
• 
Other Process Industries 
• 
Petrochemical 
 
A majority of our revenues are generated by deploying technicians and inspectors at our customers' locations. A majority of our 
revenues from aerospace and defense as well as certain manufacturing customers are generated by performing inspections and 
testing at our various in-house laboratories. 
We generated revenues of $729.6 million, $705.5 million and $687.4 million for the years ended December 31, 2024, 2023 and 
2022, respectively. We generated net income of $19.0 million, net loss of $17.4 million and net income of $6.6 million for the 
years ended December 31, 2024, 2023, and 2022, respectively. For the years ended December 31, 2024, 2023 and 2022, we 
generated approximately 81%, 82% and 83%, respectively, of our revenues from our North America segment. Our revenues are 
diversified, with our top ten customers accounting for approximately 36%, 35% and 33% of our revenues during the years

ended December 31, 2024, 2023 and 2022, respectively, with no customer accounting for greater than 10% of our revenues in 
any such year. 
  
OUR SPECIALIZED SOLUTIONS 
As a provider of asset protection solutions, we combine our industry-leading services, products, data management and 
analytical solutions technologies to provide a unique and custom-tailored solution for each customer’s individual asset 
protection needs, ranging from routine inspections to complex, plant-wide asset integrity management programs. 
Field Inspections 
Our field inspections portfolio includes traditional and advanced NDT techniques and inline inspection for pipelines. We offer 
these solutions on an individual basis, or as parts of enterprise inspection and testing programs. 
NDT is the examination of an asset without materially impacting its structural integrity. The ability to inspect infrastructure 
assets and not interfere with their operating performance makes NDT a highly-attractive alternative to many traditional 
techniques, which may require shutting down an asset or entire facility. Typical issues for which our technicians inspect include 
potential corrosion, cracking, pitting, leaking, faults and flaws in piping, storage tanks and pressure vessels, as well as a wide 
range of other industrial assets and public infrastructure.  
Our automated data acquisition solutions utilize smart sensing and monitoring, robotic inspection systems, and digitized spot 
inspections to provide asset integrity data with greater insight into current and potentially future asset conditions. 
Field inspection services lend themselves to integration with our other offerings, and as such have often served as the initial 
entry point to more advanced customer engagements that require additional solutions. After an initial field inspection is 
performed, we are able to provide multiple supplemental solutions, such as maintenance services, engineering consulting and 
data analytical solutions services we provide, that further serve to solidify our relationships with our customers and drive 
additional revenue. 
Data Analytical Solutions 
The asset protection solutions that we provide throughout our customers’ asset lifecycles generate mechanical integrity data that 
needs to be effectively archived, managed, and analyzed. A common difficulty that our customers face is the ability to easily 
access and analyze large volumes of data from multiple data collection and input sources. We recognize that this data is most 
valuable to our customers when it is accessible and integrated (regardless of vendor, tool, or facility), and we have taken 
significant steps to digitalizing asset protection processes through our data analytical solutions product offerings. 
 
Our data analytical solutions capabilities capture asset data to help our customers follow regulatory compliance, ensure 
mechanical integrity, and reduce unplanned outages. We capture data using manned and automated techniques that minimize 
the impact on our customers' operations. Customers can access our collected data for all facilities, structures, and assets that we 
manage from one easy to use dashboard, which enables customers to evaluate trending and benchmarking across multiple sites 
seamlessly. 
 
Customer data is managed in our asset protection software ecosystem, OneSuite. Our OneSuite software platform offers 
functions of our popular software and services brands as integrated applications in a cloud environment. Our OneSuite software 
platform serves as a single access portal for customers' data activities and provides access to 90 plus integrated applications 
being offered in one centralized platform.  
 
Many customers take advantage of our data analytics capabilities that utilize technology to automatically generate insights and 
actionable recommendations that can be implemented to improve our customers' overall productivity. Our managed services 
integrate our data capabilities with data analysts, field personnel and engineers to provide a comprehensive solution to our 
customers that reduces our customers' overall costs.

Our customers within the oil and gas and petrochemical industries take advantage of our industry-leading application Plant 
Condition Management Software ("PCMS®"). This application is one of the most widely used asset integrity management 
systems (“AIMS”). We estimate that our PCMS application is currently used by approximately 50% of the U.S. refiners, as well 
as by leading midstream pipeline energy companies and major oil and gas companies in Canada and Europe. This allows us to 
provide our customers with industry-leading insights across all of their facilities and enables us to provide additional software 
and solutions to these customers and perform recurring maintenance where necessary. 
 
Our pipeline customers utilize our Onstream® services and New Century® software platform to capture, manage and analyze 
pipeline integrity data in the midstream and upstream sectors of the oil and gas industry. We provide among the most 
comprehensive, data-driven pipeline protection solutions available to the industry. Our proprietary pipeline data analysis 
solutions enable deep integration of inline inspection ("ILI") big data with real-time risk analytics and business intelligence 
("BI") to provide capabilities for supporting pipeline integrity, which we believe provides us with an important competitive 
advantage. 
 
Our wind, power and infrastructure customers implement our online condition-monitoring solutions that provide real-time 
reports and analysis of infrastructure to alert facility personnel to damages before critical failures occur, while our flexible, IIoT 
compatible, cloud-based online monitoring portal centralizes and analyzes all collected monitoring data. These monitoring 
solutions are often installed in hazardous or hard-to-reach locations, helping to enhance safety by reducing the need to send 
technicians into unsafe locations.  
 
In-house Laboratory Testing 
Our network of in-house laboratories located across North America and Europe offers quality assurance and quality control 
("QA/QC") solutions for new and existing metal and alloy components, materials, and composites. 
Our in-house laboratories work with our customers to test and measure utilized components throughout their lifetimes, from

ASSET PROTECTION INDUSTRY OVERVIEW 
Asset protection plays a crucial role in assuring the integrity and reliability of critical infrastructure. As an asset protection 
solutions provider, we seek to maximize the uptime and safety of critical infrastructure, by helping customers to detect, locate, 
mitigate, and prevent damages such as corrosion, cracks, leaks, manufacturing flaws and other concerns to operating and 
structural integrity. In addition to these core utilities, the storage and analysis of collected inspection and MI data is also a key 
aspect of asset protection. 
NDT has historically been a prominent solution in the asset protection industry due to its capacity to detect defects without 
compromising the structural integrity of the tested materials or equipment. Traditionally, the supply of NDT inspection services 
has been provided by many relatively small vendors, who provide services in a more localized geographic region. A trend has 
emerged, however, for customers to increasingly engage a select few vendors capable of providing a wider spectrum of asset 
protection solutions for global infrastructure, in addition to an increased demand for advanced non-destructive testing 
("ANDT") solutions and data acquisition software, both of which require a highly-trained workforce. 
Due to these trends, those vendors offering integrated solutions, scalable operations, skilled personnel and a global footprint are 
expected to have a distinct competitive advantage. Moreover, we believe that vendors that are able to effectively deliver both 
advanced solutions and data analytics, by virtue of their access to customers’ data, create a significant barrier to entry for 
competitors, leading to the opportunity to further create significant recurring revenues. 
Key Dynamics of the Asset Protection Industry 
We believe the following represent key dynamics of the asset protection industry, and that the market available to us will 
continue to grow as these macro-market trends continue to develop: 
Digital Transformation of Asset Protection. Plants in the oil and gas, petrochemical and other process industries are recognizing 
the need to evolve their traditional, paper-based mechanical integrity programs in favor of digitalized solutions. The rise of big 
data intelligence, and our data analytical solutions offerings, provide our customers with actionable insights from raw asset 
integrity data. The growing digitization of asset protection provides opportunities for contractors with a wide range of asset 
protection expertise and integrated data platforms to provide customers with data analytical solutions to help customers 
maximize uptime while controlling costs. 
Extending the Useful Life of Aging Infrastructure While Increasing Utilization. Due to the prohibitive costs and challenges of 
building new infrastructure, many companies have chosen to extend the useful life of existing assets through enhancements, 
rather than replacing these assets. This has resulted in the significant aging and increased utilization of existing infrastructure in 
our target markets. Because aging infrastructure requires more frequent inspection and maintenance in comparison to new 
infrastructure, companies and public authorities continue to spend on asset protection to ensure their aging infrastructure assets 
continue to operate effectively.

Outsourcing of Non-Core Activities and Technical Resource Constraints. Due to the increasing sophistication and automation of 
asset protection programs, a decreasing supply of skilled professionals and increasing governmental regulations, companies are 
increasingly outsourcing NDT to third-party providers with advanced solution portfolios, engineering expertise and trained 
workforces. 
Increasing Corrosion from Low-Quality Inputs. The increased availability and low cost of crude oil from areas such as shale 
plays and oil sands resources have led to the use of lower-grade raw materials and feedstock. This leads to higher rates of 
corrosion, especially in refining processes involving petroleum with higher sulfur content, which increases the need for asset 
protection solutions to detect and/or proactively prevent corrosion-related issues. 
Increasing Use of Advanced Materials. Customers in various target markets - particularly aerospace and defense - are 
increasingly utilizing advanced materials, such as composites and other unique technologies in their assets. These materials 
often cannot be tested using traditional NDT techniques. We believe that demand for more advanced testing and assessment 
solutions will increase as the utilization of these advanced materials increases during the design, manufacturing, operating and 
quality control phases.  
Meeting Safety Regulations. Owners and operators of refineries, pipelines and petrochemical and chemical plants increasingly 
face strict government regulations and more stringent process safety enforcement standards. This includes the continued 
implementation of the Occupational Safety and Health Administration’s National Emphasis Program. Failure to meet these 
standards can result in significant financial liabilities, increased scrutiny by government and industry regulators, higher 
insurance premiums and tarnished corporate brand value. As a result, these owners and operators are seeking highly-reliable 
asset protection suppliers with a track record of assisting customers in meeting increasingly stringent regulations. Our 
customers benefit from our extensive engineering consulting base that supports them in devising MI programs that both meet 
regulatory compliance standards and enable enhanced safety and uptime at the customer's facilities. 
Expanding Addressable End-Markets. The continued emergence of and advances in asset protection technologies and software-
based systems are increasing the demand for asset protection solutions in applications where existing techniques were 
previously ineffective. Our range of service offerings and advanced digital technologies allows us to meet the requirements of 
chemical producers to continuously monitor and provide advanced digital analytical solutions for our customers'. Also, our 
advanced digital analytical solutions allow us to provide real-time monitoring to a variety of customers across infrastructure end 
markets.  
Expanding Aerospace and Defense Industry. We believe that increased demand in the defense and private space industries will 
continue to grow over the next several years in the commercial industry due to the approximately decade-long backlog for next-
generation commercial aircraft to be built, driving the need for advanced solutions that improve cost and quality efficiencies. 
Demand continues to be stable in the defense industry while demand in the private space industry is growing.  
We continue to optimize our in-house laboratories to meet the growing demands of commercial aerospace and private space end 
markets. We continue to implement operational efficiencies and new technologies to be able to meet customer demand and 
needs as they arise. As a result, we are a trusted partner in the private space industry for our customers. 
Crude Oil Prices. Volatility in the energy sector has been profound during the 2015-2022 period with moderation occurring in 
2023. The collapse of world oil prices in 2015 and 2016 undermined industry expansion. While energy prices recovered in 2017 
and 2018, they once more declined, and subsequently rebounded in the second half of 2021 and the first half of 2022 with near 
record high prices and crack spreads. This resulted in refineries delaying turnarounds during 2022 until oil prices decreased and 
stabilized in the second half of 2022. The stabilization continued throughout 2023 without major peaks and fluctuations as seen 
in prior periods. The on-going war in Ukraine and the conflict in the Middle East between Israel and Hamas, coupled with 
continued macroeconomic uncertainty throughout 2024, are expected to continue to significantly influence oil prices for the 
foreseeable future.  
Expanding Pipeline Integrity Regulations: The United States Pipeline & Hazardous Materials Safety Administration’s “Mega 
Rule” adopted in October 2019, expands pipeline integrity regulations on more than 500,000 miles of pipelines that carry 
natural gas, oil and other hazardous materials throughout the United States. Some of these requirements will take operators 
decades to fulfill. These regulations require inspection and integrity data records throughout a pipeline’s lifetime to be “reliable, 

Table of Contents 
10 
traceable, verifiable, and complete,” increasing the demand for integrated inspection, engineering, monitoring, and data 
management and analysis solutions. 
Consolidation of Refineries: Consolidation of refinery ownership will create both pressure on refinery service providers due to 
increased customer purchasing power and provide an opportunity to those same refinery service providers to become preferred 
providers to these larger customers.  
 
Our Competitive Strengths 
We believe the following competitive strengths contribute to our being a leading provider of asset protection solutions and will 
allow us to further capitalize on growth opportunities in our industry: 
OneSource Provider for Asset Protection Solutions. We believe we have one of the most comprehensive portfolios of integrated 
asset protection solutions worldwide, which positions us to be a leading single-source provider for our customers’ asset 
protection requirements. This is particularly a competitive strength in regards to turnarounds and shutdowns - during which 
facilities temporarily cease portions of their operations in order to perform plant-wide inspections, maintenance and repairs - as 
the services being requested and performed during these work stoppages make up significant portions of refinery, process and 
power plant maintenance budgets. Demand for our solutions increases during these outages, as facilities seek third-party 
providers to perform a wide spectrum of asset protection operations while the plant is offline. In addition, as companies are 
increasingly outsourcing their NDT needs to third-party providers, we believe that the ability to offer a comprehensive package 
of solutions provides us with a competitive advantage. 
Integrated Data Management: Our expertise and proprietary research and development in data analytical solutions throughout 
the asset protection cycle provides us with a competitive advantage. With solutions for integrated data acquisition, storage, 
visualization and analytics, our integrated data analytical solutions have us well-positioned for the oil and gas industry's 
increasing movement towards digitalizing and centralizing asset protection to fewer, highly-skilled and multi-disciplined 
vendors. Many of our data analytical solutions are platform-agnostic, allowing us to integrate into customers' existing 
operations, and thereby expanding the potential customer pool for our solutions. Our expertise and experience also allow us to 
tailor our offerings to meet specific customer needs, which sets us apart from our competitors. Our presence in our customers’ 
operations throughout their asset lifecycles also ideally positions us to be their primary vendor to centralize their asset integrity 
data collection, management and analysis, creating mutually-beneficial opportunities to scale our relationships. 
Long-Standing Trusted Provider to a Diversified and Growing Customer Base. We have become a trusted partner to a large and 
growing customer base across numerous global markets through our proven, decades-long track record of successful operations. 
Our customers include some of the largest and most well-recognized firms in the oil and gas, chemicals, power generation and 
transmission and aerospace and defense industries, as well as public authorities.

back several decades of operations. We have gained this through our industry leadership in developing advanced asset 
protection solutions, including research and development of advanced NDT technologies and applications, process engineering 
technologies, online plant asset integrity management with sensor fusion; and enterprise software solutions for plant-wide and 
fleet-wide inspection data archiving and management. 
Technological Research and Development. The inspection and testing industry continues to move towards more advanced, 
automated solutions, requiring service providers to find safer and more cost-efficient inspection techniques. We believe that we 
remain ahead of the technological curve by backing our extensive industry expertise with the investment of resources in

research and development. Some of the advanced inspection technologies developed by our internal research and development 
teams include an automated radiographic testing crawler for corrosion under insulation ("CUI") inspections in above ground 
pipelines and piping; our Large Structure Inspection scanner, and our real-time radiography crawler for 360° inspections of 
pipeline girth welds. 
Collaborating with Our Customers. We have historically expanded our asset protection solution portfolio in response to our 
customers’ unique performance specifications. Our technology packages have often been developed in close cooperation and 
partnership with key customers and industry organizations. 
Experienced Management Team. Our management team has a track record of asset protection organizational leadership. These 
individuals also have successfully driven operational growth organically and through acquisitions, which we believe is 
important to facilitate future growth in the asset protection industry. 
Our Growth Strategy 
Our growth strategy emphasizes the following key elements: 
Continue to Digitalize Asset Protection Data and Processes. We place a data-centric focus on asset protection, enabling our 
customers to ease some of their biggest areas of concern (particularly the timely and accurate transfer of asset integrity data 
from the field to the data management systems, as well as the data’s visibility and accessibility once uploaded). We expect that 
the demand for our data analytical solutions which provides big data intelligence and remote data visibility will continue to 
grow, and we are investing in data analytical solutions that help our customers visualize and generate actionable insight from 
their asset integrity data, regardless of data input. We are also actively seeking to optimize our customers’ asset protection 
workflows and processes, by creating digital paths between data applications to increase data visibility and reduce manual data 
entry and human error. We have provided value added services to our customer, and unlocked long-term value for our 
customers when our digital solutions are combined with our traditional testing and inspection services. The bundling of these 
services provide meaningful value and insight to our customers and show the breadth and depth of our technologies, which 
differentiates us from our competitors. 
Expand Our Focus in the Aerospace and Defense Industries. We believe that the introduction of next-generation airframes, 
aircraft engines and the increasing demand of private space flight has created an inherent demand for inspection, testing, 
machining and mechanical services required for the production of parts. The recent interest in the use of additive manufacturing 
techniques to create components also necessitates advanced inspection and testing solutions.  
We remain optimistic about the growth of the defense industry as the useful lives of legacy systems in the industry are extended 
and next generation systems are brought online. As a result, we are uniquely positioned to serve this industry by providing 
inspection and testing services to meet the demands of our customers.  
Expand Our Focus in the Pipeline Integrity Industry. We intend to continue broadening our solutions for the pipeline market. 
Recent industry regulations significantly expanded pipeline integrity management regulations, requiring pipeline 
owner/operators to inspect, document, and assess the risk of operating conditions for existing lines. This provides us with the 
opportunity to provide asset protection solutions for both the new construction and integrity phases. In 2019, we acquired a 
company that provides pipeline integrity management software and services to energy transportation companies. We acquired 
an inline inspection provider in 2018 and have implemented our PCMS software for several pipeline operators to support their 
integrity data management. These digital assets increase our ability to provide meaningful insights to customers in an efficient 
manner that creates value to our customers, which many of our competitors are unable to offer. 
Expanding our Mechanical Services Portfolio. We believe that performing mechanical services to complement inspections, 
such as removing and reapplying insulation or preparing surfaces for coating or painting, is an important market differentiator 
for us. This is particularly true, for example, when considering the cost-efficiencies our customers realize when our rope access 
technicians perform these services at height without the use of scaffolding. Many of our customers already require these 
services, but utilize multiple vendors to do so, creating an opportunity for us to provide greater value to a customer base that 
increasingly requires enhanced speed and efficiency.

Continue to Develop Technology-Enabled and Digital Asset Protection Solutions. We intend to maintain and enhance our 
technological leadership by continuing to invest in developing new technology, applications and data services. The release of 
our OneSuite ecosystem underscores our dedication to continue deepening synergies between our solutions to provide our 
customers with uniquely-integrated offerings, which we believe makes us a more attractive partner for customers seeking to 
centralize their asset protection. We have actively continued to develop technologies that enhance the flow of data throughout 
multiple operational phases and facilities, through our integrated pipeline integrity data portfolio, and our cloud-based 
monitoring data portal. 
Our focus is to provide our customers with a comprehensive solution for all of their asset protection needs. As several of the 
industries in which we serve face cost pressures, we continue to position ourselves to be a trusted partner to improve our 
customers' operational efficiency by reducing their costs and increasing the uptime for their assets, while remaining compliant 
with regulatory standards. We achieve this through a number of our services, including software, data services, engineering & 
consulting, providing sensors and real-time continuous monitoring services. When customers chose to use a variety of these 
services we are able to reduce their annual maintenance budgets by optimizing uptime for their assets. We are focused on 
further developing our services to help differentiate us against our competitors. We are also focused on expanding our customer 
base to provide our services and address the needs of customers in the industries we serve and industries we are looking to 
expand into in the future.  
Expand our Solution Offerings to Existing Customers. We believe that branching into adjacent, complementary services, such 
as mechanical services, increases our value proposition and our ability to capture additional business. Many of our customers 
are multinational corporations with asset protection requirements at multiple locations. We believe that expanding our solution 
offerings and merging and visualizing data across facilities for enterprise data analysis, combined with the trend of customers 
outsourcing asset protection to service providers with integrated offerings, provides opportunities for significant additional 
recurring revenues. We continue to remain focused on further developing our inspection and testing services to our current 
customer base and diversifying the end markets we serve. We are also focused on growing our capabilities and services that can 
provide a stronger value proposition to our customers. 
Continue to Expand Our Customer Base into New End Markets. We believe we have significant opportunities to expand our 
customer base in relatively new end markets, including the renewable energy industry, specifically, wind and other alternative 
energy, natural gas transportation industries, data centers, pipeline integrity and additive manufacturing. The expansion of our 
addressable markets is being driven by the increased recognition and adoption of advanced asset protection technologies (such 
as unmanned drone inspection devices, robotics, etc.) that are supplanting traditional methods.  
Capitalize on Acquisitions. We have completed several acquisitions to supplement and enhance our solutions, add new 
customers, expand our sales channels and accelerate our expected growth. Due to our focus on organic revenue growth and 
restrictions related to the debt covenants in our credit facility, we do not expect to make any acquisitions in 2025 other than 
small acquisitions with the approval from the lenders under our credit facility. However, we expect to make selective 
acquisitions beyond 2025.

Our Target Markets 
 
Overview 
  
We operate in a highly competitive, but fragmented market. Domestically, the market is serviced by several national 
competitors and many regional and/or local companies. Internationally, our primary competitors are divisions of large 
companies, with additional competition from small independent local companies which may be limited to a specific product, 
service or technology and focused on a niche market or geographic region. We focus our strategic sales, marketing and product 
development efforts on a range of infrastructure-intensive based industries and governmental authorities. We view energy-
related infrastructure and commercial aerospace as our largest market opportunities. We perform inspection and mechanical 
services for customers in both industries. 
 
Our revenues are comprised of services offerings at our laboratories and at customer facilities. Data Analytical Solutions

In the energy market, there are various economic indicators that drive our business, especially in the U.S. domestic markets.  It 
is unclear what the short- and long-term effects of the war between Russia and Ukraine are likely to have on the world economy 
and certain of our target markets, including particularly the oil and gas market. Excerpted below are forecasts from various 
Energy Information Administration ("EIA") outlook reports, which are subject to change based on these factors: 
 
Electricity generation from coal is projected to continue to fall throughout the mid to late 2020s and the decrease will be 
partially offset by an increase in the forecast of combined utility-scale solar and wind generation, along with other sources.  
 
The EIA noted U.S. crude oil production averaged 11.9 million barrels per day (bpd) in 2022, rose to an average 12.9 million 
bpd in 2023 and rose again in 2024 to an average 13.2 million bpd in 2024. The EIA forecasts production to continue to 
increase to an average of 13.5 million bpd in 2025.  
 
Oil and Gas 
We supply oil and gas asset protection solutions to downstream (refining), midstream (transportation and storage) and upstream 
(exploration and production) operations of our customers. 
We use our vast solutions portfolio to help identify current and future asset performance, and actively prevent, mitigate or 
otherwise address potential issues, including corrosion, cracking, leaking and other damages that may lead to safety, 
productivity or environmental concerns. Our solutions help identify conditions that if not remedied, could lead to potential 
catastrophic failures in tanks, vessels, valves, buried and above ground pipelines, pumps, motors, compressors and other critical 
assets found throughout the oil and gas production and delivery supply chain.  
We actively seek to evolve our solutions through technological enhancements and research and development to discover new 
applications. Online monitoring and permanently-mounted sensors, as well as the use of drones and other alternative delivery 
devices, are all being considered as oil and gas infrastructure owners look to “smart” technologies that reduce human 
intervention, while delivering highly-accurate inspection and integrity data. We also have actively sought to further enhance our 
integrated approach to asset protection, through the development of our complementary mechanical service portfolio. 
In general, the oil and gas market is poised to leverage digital solutions to facilitate process improvements as well as increase 
plant reliability and improve process and personnel safety. This provides an opportunity for us to synergistically leverage our 
digital asset protection solutions. Digital transmission of data in various industry sectors, with built-in analytic functions, will 
allow our customers to better leverage inspection data that is being generated in the field. 
While we expect off-stream inspection of critical assets to remain a routine practice, we anticipate an increase in the demand for 
non-invasive or on-stream inspections. Non-invasive inspections enable companies to minimize the costs associated with 
shutting down equipment during testing, while enabling the economic and safety advantages of advanced planning and/or 
predictive maintenance. 
Aerospace and Defense 
The aerospace industry continued to experience increased backlog and production levels in 2024, with such levels approaching 
and exceeding pre-COVID-19 levels for certain OEMs throughout 2024. We serve this rapidly growing target market by 
providing a full range of inspection, testing, machining, mechanical, finishing, additive manufacturing and equipment solutions, 
for which we are Nadcap certified. Our state-of-the-art in-house testing laboratories maintain numerous accreditations from 
industry organizations, including Nadcap, and some of the largest manufacturers in the world, such as Boeing, Safran, Airbus, 
Bombardier and Embraer. 
Advanced composite materials found in new classes of aircraft require advanced asset protection solutions, including x-ray of 
critical engine components, ultrasonic fatigue testing of complete aircraft structures and corrosion detection and other critical 
components. Many OEMs are shifting towards condition-based maintenance utilizing embedded monitoring sensors to track 
component structural and operational integrity over time as opposed to performing maintenance on time-based intervals. We 
expect demand for our solutions to increase with the adoption of these new-age materials and distributed online sensor

networks. We also expect demand for asset protection solutions to increase with the continued adoption of additive 
manufacturing techniques.  
Industrials 
The quality control requirements driven by the need for zero-to-low-defect component tolerance within automated, robotic-
intensive industries such as automotive, consumer electronics and medical industries serve as key drivers for increased demand 
in asset protection, particularly for in-house inspection and testing. We expect that increasingly stringent quality-control 
requirements and competitive forces will drive the demand for more-costly finishing and polishing which, in turn, creates 
opportunities for integrated partnerships between us and our customers throughout the production lifecycle. 
Power Generation and Transmission 
We provide asset protection solutions for customers in the combined cycle, fossil, nuclear, transmission and distribution and 
wind/alternative energy industries. We believe that in recent years, acceptance of asset protection solutions has grown in this 
industry due to the aging of critical power generation and transmission infrastructure. 
The growing availability of cheap natural gas, along with environmental concerns with coal, has stimulated the construction of 
new natural gas-fired power plants across North America, creating opportunities for us to provide specialized solutions in 
multiple phases. These include facility design consultations, NDT services during construction and plant operations and long-
term condition monitoring. We anticipate increased growth in these types of plants as natural gas pricing remains low, and the 
environmental impacts of coal remain unattractive to the public.  
 
We also offer solutions for inspection, maintenance, monitoring and data services for wind turbines and their components. 
These include NDT services — often performed through rope and/or drone access — to identify corrosion, cracking, and other 
defects that can affect the safety and operational effectiveness of wind turbines, along with remedial solutions to repair minor 
damages identified during inspections. 
 
Other Process Industries 
Our asset protection solutions are crucial for process industries, or industries in which raw materials are treated or prepared in a 
series of stages, including chemicals, pharmaceuticals, food processing, pulp and paper and metals and mining. As the process 
facilities are increasingly facing aging infrastructure, high utilization, growing capacity constraints and increasing capital costs, 
we believe asset protection solutions will continue to grow in importance in maintenance planning, quality and cost control and 
prevention of catastrophic failure. 
Infrastructure, Research and Engineering 
We believe that high-profile infrastructure catastrophes have caused public authorities to more actively seek ways to prevent 
similar events from occurring. Public authorities tasked with new construction and maintenance of existing public infrastructure 
increasingly use asset protection solutions to inspect these assets, including the use of embedded sensors to enable online 
monitoring throughout the life of the asset. 
We have provided testing and structural health monitoring and data analytical solutions on bridges and structures worldwide, 
including some of the largest and most well-known bridges in the United States and United Kingdom. Our sensors continuously 
monitor these assets, alerting owner/operators when defects are detected. Our monitoring teams also provide regular reports that 
include early warnings of suspect areas before an alarm is generated. 
Petrochemical 
We provide asset protection NDT services for customers within the petrochemical industry, as they transform byproducts into 
goods which are utilized in many end products such as plastics, soaps, fertilizers, synthetic fibers and rubber. Our solutions help 
identify conditions that if not remedied, could lead to potential catastrophic failures in tanks, vessels, valves, buried and above 
ground pipelines, pumps, motors, compressors and other critical assets found throughout the petrochemical production process.

We actively seek to evolve our solutions through technological enhancements and research and development ("R&D") to 
discover new applications. Online monitoring and permanently-mounted sensors provide real-time data to petrochemical 
owners and operators and provide an opportunity for us to synergistically leverage our asset protection solutions into our 
platform, OneSuite. Digital transmission of data in various industry sectors, with built-in analytic functions, will allow our 
customers to better leverage inspection data that is being generated in the field. We also have actively sought to further enhance 
our integrated approach to asset protection, through the development of our complementary mechanical service portfolio. 
Customers 
  
We provide our asset protection solutions to a global customer base of diverse companies primarily in our target markets. No 
customer represented 10% or more of our revenue in any of the years ended December 31, 2024, 2023 or 2022. 
 
Geographic Areas 
 
We have operations in 11 countries and occasionally conduct business in a few other countries. Most of our revenues are 
derived from our U.S., Canadian and European operations and we do not have operations in Russia, and we do not do business 
in Russia, Ukraine or other areas which are impacted by the on going war between Russian and Ukraine. See Note 2-Revenue 
and Note 19-Segment Disclosure to our audited consolidated financial statements in this Annual Report for further disclosure of 
our revenues, long-lived assets and other financial information regarding our international operations. 
 
Sales and Marketing 
  
We sell our asset protection solutions through our direct sales and marketing activities worldwide. In addition, our project and 
laboratory managers, as well as our management, are trained on our solutions and often are the source of sales leads and 
customer contacts. Our direct sales and marketing teams work closely with our customers to demonstrate the benefits and 
capabilities of our asset protection solutions, refine our asset protection solutions based on changing market and customer needs 
and identify potential opportunities. We divide our sales and marketing efforts into services sales, products and systems sales 
and marketing and utilize marketing automation and customer relationship management ("CRM") systems to collect, manage 
and collaborate customer information with our teams globally. Our CRM systems also provide critical data to provide accurate 
forecasting and reporting.   
  
Manufacturing 
  
Most of our hardware products are manufactured in our Princeton Junction, New Jersey facility. This facility includes the 
capabilities and personnel to fully produce all of our AE products and NDT Automation Ultrasonic equipment. We also design 
and manufacture automated ultrasonic systems and scanners in France. 
 
Human Capital 
 
As of December 31, 2024, we had approximately 4,800 employees worldwide, of which 3,200 were located in the United 
States, 500 in Canada and 1,100 in our other non-U.S. locations. Our employees include full, part time and contract employees 
throughout our organization. As described below, we value our employees and have established various programs to promote 
the satisfaction, health and safety of our employees. Less than 0.01% of our employees in the United States are unionized. 
 
Our employees are key to achieving our goals and strategy. We have committed resources throughout our organization to ensure 
that we are attracting, developing, and retaining talented employees needed to support all aspects of our activities. Our core 
values and business ethics guide and direct all activities undertaken by us. 
 
The health and safety of our employees is paramount. We have also developed key initiatives and strategies regarding our talent 
and people initiatives. Below, we describe some of the key initiatives and values around health and safety. Management 
regularly updates our board of directors (the "Board") with regards to our safety and employee strategy and our performance in 

Table of Contents 
19 
these areas. In 2020, our Board established the Environmental, Social and Safety Committee. This Committee, which consists 
of independent directors, monitors and oversees the strategic direction of our initiatives in support of our core values and our 
environmental, social and governance initiatives. 
 
Talent, Leadership and Employee Development 
 
Employee development and engagement begins with our senior management team, which has considerable industry experience 
and expertise.  
 
We provide employees the ability to gain additional professional certifications to contribute to their career advancement. We 
utilize a web-based training center which is available to field technicians for career advancement and includes over 500 web-
based classes. In addition, we are committed to ensuring all employees are compensated at a living wage. All local minimum 
wage requirements are met and where no wage laws are in place, employees are compensated competitively, in accordance with 
industry standards. 
 
Our human rights policy places a high priority on diversity and equal opportunity and provides our employees with 
management’s expectations related to human rights and labor practices.  
 
We also instituted a program that focuses on our connection by a common thread of caring – about one another, our customers, 
the environment, and the work we do. We seek to foster a culture of togetherness, safety, respect, and contribution, which 
enables each individual member of our Company to feel that he or she is a part of something bigger. A community of caring 
professionals with a genuine passion for helping people and making a difference together – that is the heart of the program we 
call “Caring Connects.” 
 
Our Safety-Conscious Culture 
 
We consider safety the backbone of our operations. Our asset protection solutions aim to ensure that industrial assets and 
facilities remain in safe, reliable working condition, which in turn enhances safety for our customers, the public, and the 
environment. Our laboratory and field personnel are trained to operate according to strict safety and quality standards so that 
our processes and procedures regarding hazardous materials, worker safety, and accident prevention are sound and effective. 
Further to this, we are constantly evaluating these processes and procedures to ensure that they remain of high quality and are 
effective. We also consider changes in the manner in which work is performed as a result of lessons that have been learned from 
any sources, such as industry data. We work to help ensure that our customers are in full compliance with all federal, state, and 
local regulations. Our practices, policies and procedures are designed to help ensure we perform our duties through the use of 
safe, industry-best practices, seeking to minimize risk wherever possible.  
 
We emphasize a “MISTRAS’ safety-conscious” culture with the intent that it becomes embedded in the day-to-day work of all 
our employees. We use various training tools and other practices to instill attitudes, beliefs, perceptions, and values that all 
employees share in the mandate to create and maintain a safe work environment for all.  
 
We continuously monitor our safety performance through analysis of our company-wide safety statistics, which help us to 
determine behavioral trends while also instilling a culture of proactivity. For the year ended December 31, 2024, our Total 
Recordable Incident Rate ("TRIR") was 0.19 while Days Away, Restricted and Transferred Rate was 0.06 and Lost Work Day 
Rate was 0.03. For the year ended December 31, 2023, our TRIR was 0.3.  
 
Seasonality 
  
Our business is seasonal. This seasonality relates primarily to our oil and gas target market, and to a lesser extent within our 
other target markets. U.S. refineries’ non-peak periods are generally in the fall, when they are retooling to produce more heating 

Table of Contents 
20 
oil for winter, and in the spring, when they are retooling to produce more gasoline for summer. The peak periods for these 
customers are the summer and winter months, when they run at peak capacity and are not retooling or performing turnarounds 
or shut downs. As a result, our revenues in the summer and winter months are typically lower than our revenues in the fall and 
spring, when demand for our asset protection solutions from the oil and gas as well as the fossil power industries increases 
during their non-peak production periods. Because we are increasing our work in the fall and spring, our cash flows are lower in 
those quarters than in the summer and winter, as collections of receivables lag behind revenues. We expect that this seasonality 
will continue. 
  
Competition 
  
We operate in a highly competitive, but fragmented, market. Our primary competitors include large public and private 
companies, divisions of large companies and various small companies which generally are limited to a specific product or 
technology and focused on a niche market or geographic region. We believe that few, if any, of our competitors currently 
provide the full range of asset protection and NDT products, PCMS and the traditional and advanced services solutions that we 
offer. Our competition with respect to NDT services include Acuren, SGS Group, the Team IHT Segment and APPLUS RTD. 
Our competition with respect to PCMS includes UltraPIPE, Lloyd’s Register Capstone, Inc. and Meridium Systems. In the 
traditional NDT market, we believe the principal competitive factors include project management, availability of qualified 
personnel, execution, price, reputation and quality, whereas in the advanced NDT market, reputation, quality and size tend to be 
the most significant competitive factors. We believe that the NDT market has significant barriers to entry which would make it 
difficult for new competitors to enter the market. These barriers include: (i) having to acquire or develop advanced NDT 
services, products and systems technologies, which in our case occurred over many years of customer engagements and at 
significant internal research and development expense, (ii) complex regulations and safety codes that require significant 
industry experience, (iii) license requirements and evolved quality and safety programs, (iv) costly and time-consuming 
certification processes, (v) capital requirements and (vi) emphasis by large customers on size and critical mass, length of 
relationship and past service record. 
 
Research and Development  
 
Our R&D is principally conducted by engineers and scientists at our Princeton Junction, New Jersey headquarters, and 
supplemented by other employees in the United States and throughout the world, including Canada, France, Greece the United 
Kingdom, Brazil and the Netherlands. Our total professional staff includes employees who hold Ph.D.’s and engineers and 
employees who hold Level III certification, the highest level of certification from the American Society of Non-Destructive 
Testing ("ASNT"). 
We make strategic R&D investments in our data analytical solutions technologies that support integration with our other 
solution offerings to enhance cost- and time-efficiencies, maximize uptime and safety and improve the flow of data from field 
technicians to inspection databases. These strategic investments enable us to enhance our service offerings to customers and 
provide valuable insights and predictive analysis.  
We have also invested significant research and development in pre-machining and advanced testing technologies in a purpose-
built facility for an aerospace customer, with the goal of reducing the customer’s production cycle logistics and costs. 
We also work with customers to develop new products or applications for our technology, including: 
• 
Testing of new composites; 
• 
Detecting crack propagation; 
• 
Wireless and communications technologies; and 
• 
Development of permanently embedded inspection systems to provide continuous, online, in-service monitoring of 
critical structural components.

Research and development expenses are reflected in our Consolidated Statements of Income (Loss) as research and engineering 
expenses. Our company-sponsored research and engineering expenses were approximately $1.1 million, $1.7 million and $2.0 
million for the years ended December 31, 2024, 2023 and 2022, respectively. While we have historically funded most of our 
research and development expenditures, from time to time we also receive customer-sponsored research and development 
funding. Most of the projects are in our target markets, however, a few of the projects could lead to other future market 
opportunities. 
 
Intellectual Property 
 
Our success depends, in part, on our ability to maintain and protect our proprietary technology and to conduct our business 
without infringing on the proprietary rights of others. We utilize a combination of intellectual property safeguards, including 
patents, copyrights, trademarks and trade secrets, as well as employee and third-party confidentiality agreements, to protect our 
intellectual property. 
As of December 31, 2024, we held 12 U.S. patents by direct ownership and had 5 patent applications pending in the United 
States. All the patent applications pending have been filed since 2018. While we do not rely on these patents or licenses to 
provide a majority of our proprietary asset protection solutions, certain of these patents do provide us with a competitive 
advantage and we believe they will be an asset to our growth strategy. Our trademarks and service marks provide us and our 
solutions with a certain amount of brand recognition in our markets. We do not consider any single patent, trademark or service 
mark material to our financial condition or results of operations. 
As of December 31, 2024, the primary trademarks and service marks that we held in the United States included MISTRAS®, 
our stylized globe design and our tag line "One Source for Asset Protection Solutions". Other key trademarks or service marks 
that we utilize in localized markets or product advertising include:

Many elements of our asset protection solutions involve proprietary know-how, technology or data that are not covered by 
patents or patent applications because they are not patentable or would be difficult to enforce, including technical processes, 
algorithms and procedures. We believe that this proprietary know-how, technology and data is the most important component of 
our intellectual property used in our asset protection solutions and is a primary differentiator of our solutions from those of our 
competitors. We rely on various trade secret protection techniques and agreements with our customers, service providers and 
vendors to protect these assets. All of our employees are subject to confidentiality requirements through our employee

handbook. In addition, many of our employees have entered into confidentiality and proprietary information agreements with 
us. Our employee handbook and these agreements require our employees not to use or disclose our confidential information and 
to assign to us all the inventions, designs and technologies they develop during the course of employment with us, as well as 
addressing other intellectual property protection issues. We also seek confidentiality agreements from our customers and 
business partners before we disclose any sensitive aspects of our technologies or business strategies. We are not currently 
involved in any material intellectual property claims. 
Governmental Regulations 
  
We are subject to numerous environmental, legal and regulatory requirements related to our operations worldwide. In the 
United States, these laws and regulations include, among others: the Comprehensive Environmental Response, Compensation, 
and Liability Act, the Resources Conservation and Recovery Act, the Clean Air Act, the Federal Water Pollution Control Act, 
the Toxic Substances Control Act, the Atomic Energy Act, the Energy Reorganization Act of 1974, and applicable regulations. 
In addition to the federal laws and regulations, states and other countries where we do business often have numerous 
environmental, legal and regulatory requirements by which we must abide. We evaluate and address the environmental impact 
of our operations by assessing properties in order to avoid future liabilities and comply with environmental, legal and regulatory 
requirements.

ITEM 1A.                                      RISK FACTORS 
  
This section describes the major risks to us, our business and our common stock. You should carefully read and consider the 
risks described below, together with the other information contained in this Annual Report, including our financial statements 
and the notes thereto and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” before 
making an investment decision. The statements contained in this section constitute cautionary statements under the Private 
Securities Litigation Reform Act of 1995. If any of these risks occur, our business, financial condition, results of operations and 
future growth prospects may be adversely affected. As a result, the trading price of our common stock would likely decline, and 
you may lose all or part of your investment. You should understand that it is not possible to predict or identify all risk factors 
that could impact us. For example, it is unclear what effects the on-going war between Russia and Ukraine and the conflict in 
the Middle East between Israel and Hamas are likely to have on the world economy and certain of our target markets, including 
particularly the oil and gas market, in the near and long term. In addition, macroeconomic factors such as inflation, 
unemployment, interest rates, and tariffs or trade barriers (including recent U.S. tariffs imposed or threatened to be imposed on 
China, Canada, Mexico and other countries and any retaliatory actions take by such countries) amongst others, will impact our 
business. Accordingly, you should not consider the following to be a complete discussion of all risks and uncertainties 
pertaining to us and our common stock. 
  

Table of Contents 
25 
Risks Related to Our Business 
 
Due to our dependency on customers in the oil and gas industry, we are susceptible to prolonged negative trends relating to 
this industry that could adversely affect our operating results. 
  
Our customers in the oil and gas industry have accounted for a substantial portion of our historical revenues. Specifically, they 
accounted for approximately 57%, 59%, and 56% of our revenues for the years ended December 31, 2024, 2023 and 2022, 
respectively. Although we have expanded our customer base into industries other than the oil and gas industry, we still receive a 
majority of our revenues from this industry. Our services are vital to the operators of plants, refineries, and pipelines, and we 
have expanded our services offerings, such as expanding our mechanical and in-line inspection services capabilities. However, 
economic slowdowns or low oil prices have, and could continue to, result in cutbacks in contracts for our services. In addition, 
low oil prices could depress the level of new exploration and construction, which would adversely affect our market 
opportunities. If the price of oil were to decrease, our revenues, profits and cash flows may be reduced. If the price of oil 
reaches record, or near record levels as it did in 2023, we may experience delays or deferrals in performing inspection services 
to customers in the oil and gas industry.  
 
While we continue to expand our market presence in the aerospace, power generation and transmission, and the chemical 
processing industries, among others, these markets are also cyclical in nature and as such, are subject to economic downturns. 
In addition, it is unclear what the continued effects the war between Russia and Ukraine and the conflict in the Middle East 
between Israel and Hamas are likely to have on the world economy and certain of our target markets, including particularly the 
oil and gas market, in the near and long term. However, the on-going war between Russia and Ukraine continues to create 
disruptions in the oil and gas market and the supply chain in general, which is resulting in some disruption to our business 
operations. Our European operations are currently experiencing increased costs associated with higher energy costs, among 
others, due in part to the on-going war between Russia and Ukraine. We may also experience increased costs associated with 
tariffs or trade barriers (including recent U.S. tariffs imposed or threatened to be imposed on China, Canada, Mexico and other 
countries and any retaliatory actions taken by such countries).  
 
We may be affected by climate change and market or regulatory responses to climate change  
 
Climate change could have a material adverse effect on our results of operations, financial condition, and liquidity. Restrictions 
on emissions, including those that have already been adopted and others that are expected to be adopted in the future, could 
affect our customers that (i) use commodities to produce energy, (ii) use significant amounts of fossil fuel to produce or deliver 
commodities, or (iii) manufacture or produce goods that consume significant amounts of fossil fuels or burn fossil fuels. 
Significant cost increases, government regulation, or changes of consumer preferences for goods or services relating to 
alternative sources of energy or emissions reductions could materially affect the markets we serve (including the oil and gas 
industry), which in turn could have a material adverse effect on our results of operations, financial condition and liquidity. 
Government incentives encouraging the use of alternative sources of energy also could affect certain of our customers and the 
markets we serve in an unpredictable manner. Any of these factors, individually or with one or more of the other factors, or 
other unforeseen impacts of climate change could have a material adverse effect on our results of operations, financial condition 
and liquidity. 
 
In addition, changes in international, federal, state and local legislation and regulation based on concerns about climate change 
and increasing climate-related disclosures, including the rules proposed by the SEC, could result in increased compliance and 
data collection costs if, and when, such laws and regulations become effective.  
  
Our international operations are subject to risks relating to non-U.S. operations. 
  
For the years ended December 31, 2024, 2023 and 2022, we generated approximately 31%, 29%, and 29% of our revenues 
outside the United States, respectively. In addition, our international operations as a percentage of our business may increase 
over time. Our primary operations outside the United States are in Canada, Germany, France, the United Kingdom, the 

Table of Contents 
26 
Netherlands, and Brazil. We also have operations in Belgium, Greece, India and Mexico. There are numerous risks inherent in 
doing business in international markets, including: 
  
• 
fluctuations in currency exchange rates and interest rates; 
• 
regional micro and macro-economic pressures, inflationary costs, energy costs and geopolitical factors;

Our operating results could be adversely affected by a reduction in business with our significant customers. 
  
We derive a significant amount of revenues from a few customers. Taken as a group, our top ten customers were responsible for 
approximately 36%, 35%, and 33% of our revenues for the years ended December 31, 2024, 2023 and 2022, respectively. This 
concentration pertains almost exclusively to our North America segment, which accounted for 81%, 82% and 83% of our 
revenues for the years ended December 31, 2024, 2023 and 2022, respectively. These customers are primarily in the oil and gas 
sector. Generally, our customers do not have an obligation to make purchases from us and may stop ordering our products and 
services or may terminate existing orders or contracts at any time with little or no financial penalty. The loss of any of our 
significant customers, any substantial decline in sales to these customers or any significant change in the timing or volume of 
purchases by our significant customers could result in lower revenues and could harm our business, financial condition or 
results of operations.  
 
Our business, and the industries we currently serve, are currently subject to governmental regulation, and may become 
subject to modified or new government regulation that may negatively impact our ability to market our asset protection 
solutions. 
  
We are required to comply with various government regulations and licensing requirements. For example, the transportation 
and overnight storage of radioactive materials used in providing certain of our asset protection solutions such as radiography 
are subject to regulation under federal and state laws and licensing requirements. Our North America segment is currently 
licensed to handle radioactive materials by the U.S. Nuclear Regulatory Commission, more than 30 state regulatory agencies 
and the Canadian Nuclear Safety Commission. If we allegedly fail to comply with these regulations, we may be investigated 
and incur significant legal expenses associated with such investigations, and if we are found to have violated these regulations, 
we may be fined or lose one or more of our licenses or permits, which would prevent or restrict our ability to provide 
radiography services. In addition, while we are being investigated, we may be required to suspend work on the projects 
associated with our alleged noncompliance, resulting in loss of profits or customers, and damage to our reputation. Many of our 
customers have strict requirements concerning safety or loss time occurrences and if we are unable to meet these requirements

27 
it could result in lost revenues. In the future, governmental agencies may seek to change current regulations or impose 
additional regulations on our business. Any modified or new government regulation applicable to our current or future asset 
protection solutions may negatively impact the marketing and provision of those solutions and increase our costs of providing 
these solutions and have a corresponding adverse effect on our margins. 
  
Additionally, greenhouse gases that result from human activities, including burning of fossil fuels, have been the focus of 
increased scientific and political scrutiny and are being subjected to various legal requirements. International agreements, 
national laws, state laws and various regulatory schemes limit or otherwise regulate emissions of greenhouse gases, and 
additional restrictions are under consideration by different governmental entities. We derive a significant amount of revenues 
and profits from such industries, including oil and gas, power generation and transmission, and chemicals processing. Such 
regulations could negatively impact our customers, which could negatively impact the market for the services and products we 
provide. This could materially adversely affect our business, financial condition, results of operations and cash flows. 
  
We rely on certification of our NDT solutions by industry standards-setting bodies. We and/or our subsidiaries currently have 
International Organization for Standardization (ISO) 9001:2008 certification, ISO 14001:2004 certification and OHSAS 
18001:2007 certification. In addition, we currently have Nadcap and similar certifications for certain of our locations. We 
continually review our NDT solutions for compliance with the requirements of industry specification standards and the Nadcap 
special processes quality requirements. However, if we fail to maintain our ISO, Nadcap or other certifications, our business 
may be harmed because our customers generally require that we have these certifications before they purchase our NDT 
solutions. 
  
An accident or incident involving our asset protection solutions could expose us to claims, harm our reputation and 
adversely affect our ability to compete for business and, as a result, harm our operating performance. 
  
We could be exposed to liabilities arising out of the solutions we provide. For instance, we furnish the results of our testing and 
inspections for use by our customers in their assessment of their assets, facilities, plants and other structures. If such results 
were to be incorrect or incomplete, as a result of, for instance, poorly designed inspections, malfunctioning testing equipment or 
our employees’ failure to adequately test or properly record data, we could be subject to claims. Further, if an accident or 
incident involving a structure we tested occurs and causes personal injuries or property damage, such as the collapse of a bridge 
or an explosion in a facility, and particularly if these injuries or damages could have been prevented by our customers had we 
provided them with correct or complete results, we would likely face significant claims relating to personal injury, property 
damage or other losses. Even if our results are correct and complete, we may face claims for such injuries or damage simply 
because we tested the structure or facility in question. In addition, during the course of a single engagement, such as the 
inspection of a pipeline, we often perform tests on thousands of welds. Even if the accuracy of only a small number of these test 
results are questioned, a customer may attempt to refuse payment for the entire project. While we do have insurance, our 
insurance coverage does not cover non-payment by customers and may not be adequate to cover the damages from any of the 
prior referenced claims, forcing us to bear these uninsured damages directly, which could harm our operating results and may 
result in additional expenses and possible loss of revenues. An accident or incident for which we are found partially or fully 
responsible, even if fully insured, or even an incident at a customer or site for which we provide services although we were 
found not to be responsible, may also result in negative publicity, which would harm our reputation among our customers and 
the public, cause us to lose existing and future contracts or make it more difficult for us to compete effectively, thereby 
significantly harming our operating performance. In addition, the occurrence of an accident or incident might also make it more 
expensive or extremely difficult for us to insure against similar events in the future. 
  
Many of the sites at which we work are inherently dangerous workplaces. If we fail to maintain a safe work environment, we 
may incur losses and lose business. 
  
Many of our customers, particularly in the oil and gas and chemical industries, require their inspectors and other contractors 
working at their facilities to have good safety records because of the inherent danger at these sites. If our employees are injured 
at the work place, we could incur costs for the injuries and lost productivity. In addition, safety records are impacted by the 
number and amount of workplace incidents involving a contractor’s employees. If our safety record is not within the levels

28 
required by our customers, or compares unfavorably to our competitors, we could lose business, be prevented from working at 
certain facilities or suffer other adverse consequences, all of which could negatively impact our business, revenues, reputation 
and profitability. 
 
If our software or system produces inaccurate information or are incompatible with the systems used by our customers and 
make us unable to successfully provide our solutions, it could lead to a loss of revenues and customers. 
 
Our software and systems are complex and, accordingly, may contain undetected errors or failures. Software or system defects 
or inaccurate data may cause incorrect recording, reporting or display of information related to our asset protection solutions. 
Any such failures, defects and inaccurate data may prevent us from successfully providing our asset protection solutions, which 
could result in lost revenues. Software or system defects or inaccurate data may lead to customer dissatisfaction and could 
cause our customers to seek to hold us liable for any damages incurred. As a result, we could lose customers, our reputation 
may be harmed and our financial condition and results of operations could be materially adversely affected. 
 
We currently serve a commercial, and industrial customer base that uses a wide variety of constantly changing hardware, 
software solutions and operating systems. Our asset protection solutions need to interface with these systems in order to gather 
and assess data. Our business depends on the following factors, among others: 
 
• 
our ability to integrate our technology with new and existing hardware and software systems, of either Mistras or a 
customer; 
• 
our ability to anticipate and support new standards, especially internet-based standards; and 
• 
our ability to integrate additional software modules under development by either us or a customer, with our existing 
technology and operational processes. 
 
If we are unable to adequately address any of these factors, our results of operations and prospects for growth and profitability 
would be adversely impacted. 
 
If we are unable to attract and retain a sufficient number of trained certified technicians, engineers and scientists at 
competitive wages, changes in laws and other labor issues could materially affect our financial performance. 
  
We believe that our success depends, in part, upon our ability to attract, develop and retain a sufficient number of trained 
certified technicians, engineers and scientists at competitive wages. The demand for such employees fluctuates as the demand 
for NDT and inspection services fluctuates. When the demand for qualified technicians increases, we will often experience 
increased labor costs, which we may not recover in the amounts we can charge our customers. The markets for our products and 
services require us to use personnel trained and certified in accordance with standards set by domestic or international standard-
setting bodies, such as the American Society of Non-Destructive Testing or the API. Because of the limited supply of these 
certified technicians, we expend substantial resources maintaining in-house training and certification programs. If we fail to 
attract sufficient new personnel or fail to motivate and retain our current personnel, our ability to perform under existing 
contracts and orders or to pursue new business may be harmed, preventing us from growing our business or causing us to lose 
customers and revenues, and the costs of performing such contracts and orders may increase, which would likely reduce our 
margins. 
 
In addition, if our costs of labor or related costs increase for other reasons or if new or revised labor laws, rules or regulations or 
healthcare laws are adopted or implemented that further increase our labor costs, our financial performance could be materially 
adversely affected. 
 
Our initiatives to improve our financial performance may not achieve results within expected time frames, or at expected 
levels.

We have undertaken strategies to transform our business so that we may operate more effectively, streamline and rationalize our 
cost structures, and look for strategic opportunities to expand our revenue and become more profitable.  The extent of our future 
success depends on how successful we are in these endeavors.  
 
In 2023, we commenced a broad review of our operations, which we refer to as "Project Phoenix". Through Project Phoenix, 
we have been exploring ways to improve profitability and Adjusted EBITDA, through meaningful margin improvement and 
sustained cost savings. We have completed most phases of the project in 2023, wherein efficiency and profitability 
opportunities were identified, actionable initiatives were validated, and many of these actions have been implemented 
prospectively throughout 2024. Project Phoenix has resulted in significant cost reductions, primarily through headcount 
reductions, more efficient workflows, and streamlining of processes, and also led to developing and initiating action plans to 
increase revenue. 
 
We believe our Project Phoenix initiatives will benefit the Company and our stockholders in the long run. However, we cannot 
be certain that some of the cost reductions could result in problems with our operations, lost opportunities, weakening of 
controls and procedures or other adverse effects if we misjudged the impact of the headcount reductions and other changes that 
we have implemented and are currently implementing. In addition, headcount reductions can result in lower employee morale 
and result in employees deciding to leave the Company, which would further adversely impact our businesses. 
  
We operate in competitive markets and if we are unable to compete successfully, we could lose market share and revenues 
and our margins could decline. 
  
We face strong competition from NDT and a variety of niche asset protection providers, both larger and smaller than we are. 
Some of our competitors have greater financial resources than we do and could focus their substantial financial resources to 
develop a competing business model or develop products or services that are more attractive to potential customers than what 
we offer. Some of our competitors are business units of companies substantially larger than us and could attempt to combine 
asset protection solutions into an integrated offering to customers who already purchase other types of products or services 
from them. Our competitors may offer asset protection solutions at lower prices than ours in order to attempt to gain market 
share. Smaller niche competitors with small customer bases could be aggressive in their pricing in order to retain customers. 
These competitive factors could reduce our market share, revenues and profits. 
 
The success of our businesses depends, in part, on our ability to develop new asset protection solutions, increase the 
functionality of our current offerings and meet the needs and demands of our customers. 
  
The market for asset protection solutions is impacted by technological change, uncertain product lifecycles, shifts in customer 
demands and evolving industry standards and regulations. If we fail to execute effective business strategies, or fail to 
successfully develop and market new asset protection solutions that comply with present or emerging industry regulations and 
technology standards, our competitive standing and results could suffer. Also, new regulations or technology standards could 
increase our cost of doing business. 
  
From time to time, our customers have requested greater value and functionality in our solutions. As part of our strategy to 
enhance our asset protection solutions and grow our business, we continue to make investments in the research and 
development of new technologies, inspection tools and methodologies. We believe our future success will depend, in part, on 
our ability to continue to design new, competitive and broader asset protection solutions, enhance our current solutions and 
provide new, value-added services. Many traditional NDT and inspection services are subject to price competition by our 
customers. Accordingly, the need to demonstrate our value-added services is becoming more important. Developing new 
solutions will require continued investment, and we may experience unforeseen technological or operational challenges. In 
addition, our asset protection software is complex and can be expensive to develop, and new software and software 
enhancements can require long development and testing periods. If we are unable to develop new asset protection solutions or 
enhancements that meet market demands on a timely basis, including against possible alternative products developed and 
marketed by our competitors, we may experience a loss of customers or otherwise be likely to lose opportunities to earn 
revenues and to gain customers or access to markets, and our business and results of operations will be adversely affected. 

Table of Contents 
30 
  
Even if we develop new solutions, if our customers, or potential customers, do not see the value our solutions have over 
competing products and services, our operating results could be adversely impacted. In addition, because the asset protection 
solutions industry is evolving, we could lose insight into trends that may be emerging, which would further harm our 
competitive position by making it difficult to predict and respond to customer needs. If the market for our asset protection 
solutions does not continue to develop, our ability to grow our business would be limited and we might not be able to maintain 
profitability. If we cannot convince our customers of the advantages and value of our advanced NDT services, we could lose 
large contracts or suffer lower profit margin. 
  
The seasonal nature of our business reduces our revenues and profitability in the winter and summer and related cash 
flows. 
 
Our business is seasonal. The fall and spring revenues are typically higher than our revenues in the winter and summer because 
demand for our asset protection solutions from the oil and gas as well as the fossil and nuclear power industries increases 
during their non-peak production periods. For instance, U.S. refineries’ non-peak periods are generally in the fall, when they are 
retooling to produce more heating oil for winter, and in the spring, when they are retooling to produce more gasoline for 
summer. As a result of these trends, we generally have reduced cash flows in the fall and spring, as collections of receivables 
lag behind revenues, normally requiring us to increase our borrowings under our credit agreement. In addition, most of our 
operating expenses, such as employee compensation and property rental expense, are relatively fixed over the short term. 
Moreover, our spending levels are based in part on our expectations regarding future revenues. As a result, if revenues for a 
particular quarter are below expectations, we may not be able to proportionately reduce operating expenses for that quarter. We 
expect that the impact of seasonality will continue. 
 
Our credit agreement contains financial and operating restrictions that may limit our access to credit. If we fail to comply 
with financial or other covenants in our credit agreement, we may be required to repay indebtedness to our existing lenders, 
which may harm our liquidity. 
 
Our credit agreement contains financial covenants that require us to maintain compliance with specified financial ratios. If we 
fail to comply with these covenants, the lenders could prevent us from borrowing under our credit agreement, require us to pay 
all amounts outstanding, require that we cash collateralize letters of credit issued under the credit agreement and restrict us from 
making acquisitions. If the maturity of our indebtedness is accelerated, we then may not have sufficient funds available for 
repayment or the ability to borrow or obtain sufficient funds to replace the accelerated indebtedness on terms acceptable to us, 
or at all. We believe that it is probable, based on the Credit Agreement (as defined herein), that we will be able to comply 
with the financial covenants in our existing credit agreement and that sufficient credit remains available under the credit 
agreement to meet our liquidity needs. However, due to the uncertainties being caused by the significant volatility in oil prices 
and volatility in the aerospace production, such matters cannot be predicted with certainty. 
 
Our current credit agreement also imposes restrictions on our ability to engage in certain activities, such as creating liens, 
making certain investments, incurring more debt, disposing of certain property, paying dividends and making distributions and 
entering into a new line of business. While these restrictions have not impeded our business operations to date, if our plans 
change, these restrictions could be burdensome or require that we pay fees to have the restrictions waived. In addition, due to 
our current debt levels and restrictions related to the debt covenants in our credit facility, we do not expect to make any 
acquisitions in 2025 other than small acquisitions with the approval of the lenders under our Credit Agreement. 
 
Currency exchange rate fluctuations in various currencies in which we do business, especially the Euro and the U.S. dollar, 
could have a material adverse effect on our business, results of operations and financial condition. 
 
Most of our revenues are denominated in U.S. dollars, with the remaining amounts largely in euros, British pound sterling, the 
Brazilian Real, the Canadian Dollar and the Indian rupee. We have foreign currency exposure related to our operations in 
foreign locations and our foreign currency exposure arises primarily from the translation of our foreign subsidiaries’ financial 
statements into U.S. dollars. The exchange rates between the euro and other currencies in which we incur costs or receive 

Table of Contents 
31 
revenues, on the one hand, and the U.S. dollar, on the other hand, have changed substantially in recent years and may fluctuate 
substantially in the future. See Item 7A-“Quantitative and Qualitative Disclosures about Market Risk.”  
 
Our results of operations have been adversely affected and could be further adversely affected by certain movements in 
exchange rates, particularly if the foreign currencies in which we incur expenses appreciate against the U.S. dollar or if the 
foreign currencies in which we receive revenues depreciate against the U.S. dollar. For example, a portion of our annual sales 
and operating costs are denominated in British Pound Sterling and we have exposure related to sales and operating costs 
increasing or decreasing based on changes in currency exchange rates. If the U.S. Dollar increases in value against these foreign 
currencies, the value in U.S. Dollars of the assets and liabilities originally recorded in these foreign currencies will decrease. 
Conversely, if the U.S. Dollar decreases in value against these foreign currencies, the value in U.S. Dollars of the assets and 
liabilities originally recorded in these foreign currencies will increase. Thus, increases and decreases in the value of the U.S. 
Dollar relative to these foreign currencies have a direct impact on the value in U.S. Dollars of our foreign currency 
denominated assets and liabilities, even if the value of these items has not changed in their original currency. We do not 
currently enter into forward exchange contracts to hedge exposures denominated in foreign currencies. We may consider 
entering into hedging or forward exchange contracts in the future, as sales in international currencies increase due to growth in 
our International segment. 
 
We face risks regarding our information technology and security. 
 
Significant disruptions of our information technology systems or breaches of information security could adversely affect our 
business. We rely upon information technology systems to operate many parts of our business. We routinely collect, store and 
transmit large amounts of sensitive or confidential information, including data from the results of our testing and inspections. 
We deploy and operate various technical and procedural controls to maintain the confidentiality and integrity of such sensitive 
or confidential information. Furthermore, as we automate more of our inspection process and procedures, including through the 
use of MISTRAS Digital, we become more vulnerable to security breaches and other system disruptions. In addition, we rely 
on 
third parties for significant elements of our information technology infrastructure and, as a result, we are managing many 
independent vendor relationships with third parties who may or could have access to our confidential information. The size and 
complexity of our information technology and information security systems, and those of our third-party vendors with whom 
we contract (and the large amounts of confidential information that is present on them), make such systems potentially 
vulnerable to service interruptions or to security breaches from inadvertent or intentional actions by our employees or vendors, 
or from attacks by malicious third parties. Such attacks are of ever-increasing levels of sophistication and expertise, including 
organized criminal groups, “hacktivists” and others. Due to the nature of some of these attacks, there is a risk that they may 
remain undetected for a period of time. While we have invested in the protection of data and information technology, there can 
be no assurance that our efforts will prevent service interruptions or security breaches. Any such interruption or breach of our 
systems could adversely affect our business operations and/or result in the loss of critical or sensitive confidential information, 
and could result in financial, legal, business and reputational harm to us. We maintain cyber liability insurance. However, this 
insurance may not be sufficient to cover the financial, legal, business or reputational losses that may result from an interruption 
or breach of our systems. The occurrence or perception of security breaches in connection with our asset protection solutions or 
our customers’ concerns about internet security or the security of our solutions, whether warranted or not, would likely harm 
our reputation and business, inhibit market acceptance of our asset protection solutions and cause us to lose customers, any of 
which would harm our financial condition and results of operations. 
 
In addition, much of our computer and communications hardware is located at a single facility. We have a back-up data-center 
and storage in a different geographic area. Should a natural disaster or some other event occur that damages our primary data 
center or significantly disrupts its operation, such as human error, fire, flood, power loss, telecommunications failure, break-ins, 
terrorist attacks, acts of war and similar events, we could suffer temporary interruption of key functions and capabilities before 
the back-up facility is fully operational. 
 
Events such as natural disasters, industrial accidents, epidemics, pandemics, war and acts of terrorism, and adverse weather 

Table of Contents 
32 
conditions could disrupt our business or the business of our customers, which could significantly harm our operations, 
financial results and cash flow. 
 
Our operations and those of our customers are susceptible to the occurrence of catastrophic events outside our control, which 
may include events like epidemics, pandemics and other health crises, severe weather conditions, industrial accidents, and acts 
of war and terrorism, to name a few. We continue to actively monitor the conflict in the Middle East between Israel and Hamas, 
and the war between Russia and Ukraine and the sanctions imposed upon Russia in order to assess impacts to our customers 
and our operations. At this time, we do not believe there is a material impact on our operations, however the future impact of 
the conflict, and additional sanctions imposed, are uncertain. 
 
Any such events could cause a serious business disruption that reduces our customers’ need or interest in purchasing our asset 
protection solutions. In the past, such events have resulted in order cancellations and delays because customer equipment, 
facilities or operations have been damaged, or are not then operational or available. A large portion of our customer base has 
operations in the Gulf of Mexico, which is subject to hurricanes and tropical storms. Hurricane-related disruptions to our 
customers’ operations have adversely affected our revenues in the past. Such events in the future may result in substantial 
delays in the provision of solutions to our customers and the loss of valuable equipment. In addition, our results can be 
adversely impacted by severe winter weather conditions, which can result in lost workdays and temporary closures of customer 
facilities or outdoor projects. 
 
In addition, these events could disrupt commodity prices or financial markets or have other negative macroeconomic impacts, 
such as the conflict in the Middle East between Hamas and Israel and the on-going war between Ukraine and Russia, which 
could harm our business. 
  
Risks Related to Our Common Stock 
  
The family of our late founder and Chairman Emeritus has significant influence over the direction of our business. The 
concentrated ownership of our common stock may prevent other stockholders from influencing significant corporate 
decisions. 
  
Dr. Sotirios J. Vahaviolos, our late founder and Chairman Emeritus, who passed away on February 6, 2025, owned at the time 
of his passing, approximately 6% of our outstanding common stock, his three adult children owned, at the time of his passing  
an additional 6%, in the aggregate, and a grantor retained annuity trust he created, for which his daughter is the sole trustee, 
owned approximately 22% at the time of his passing. As a result, the family of Dr. Vahaviolos has significant control over the 
Company and they have the ability to exert substantial influence over all matters requiring approval by our stockholders, 
including the election and removal of directors, amendments to our certificate of incorporation, and any proposed merger, 
consolidation or sale of all or substantially all of our assets and other corporate transactions. This concentration of ownership 
could be disadvantageous to other stockholders with differing interests from the family of Dr. Vahaviolos. 
  
We currently have no plans to pay dividends on our common stock. 
  
We have not declared or paid any cash dividends on our common stock to date, and we do not anticipate declaring or paying 
any dividends on our common stock in the foreseeable future. To the extent we do not pay dividends on our common stock, 
investors must look solely to stock appreciation for a return on their investment. 
  
Shares eligible for future sale may cause the market price for our common stock to decline even if our business is doing 
well. 
  
Future sales by us or by our existing stockholders of substantial amounts of our common stock in the public market, or the 
perception that these sales may occur, could cause the market price of our common stock to decline. This could also impair our 
ability to raise additional capital in the future through the sale of our equity securities. We cannot predict the size of future 
issuances of our common stock or the effect, if any, that future sales and issuances of shares of our common stock, or the 

Table of Contents 
33 
perception of such sales or issuances, would have on the market price of our common stock. We currently have approximately 
170 million shares of common stock available for issuance. 
  
Provisions of our certificate of incorporation, bylaws and of Delaware law could discourage, delay or prevent a change of 
control of our company, which may adversely affect the market price of our common stock. 
  
Certain provisions of our certificate of incorporation and bylaws could discourage, delay or prevent a merger, acquisition, or 
other change of control that stockholders may consider favorable, including transactions in which our stockholders might 
otherwise receive a premium for their shares. These provisions also could limit the price that investors might be willing to pay 
in the future for shares of our common stock, thereby depressing the market price of our common stock. Stockholders who wish 
to participate in these transactions may not have the opportunity to do so. Furthermore, these provisions could prevent or 
frustrate attempts by our stockholders to replace or remove our management. These provisions: 
  
• 
allow the authorized number of directors to be changed only by resolution of our Board; 
• 
require that vacancies on the Board, including newly created directorships, be filled only by a majority vote of 
directors then in office; 
• 
authorize our Board to issue, without stockholder approval, preferred stock that, if issued, could operate as a “poison 
pill” to dilute the stock ownership of a potential hostile acquirer to prevent an acquisition that is not approved by our 
Board; 
• 
require that stockholder actions must be effected at a duly called stockholder meeting by prohibiting stockholder action 
by written consent; 
• 
prohibit cumulative voting in the election of directors, which may otherwise allow holders of less than a majority of 
stock to elect some directors; and 
• 
establish advance notice requirements for stockholder nominations to our Board or for stockholder proposals that can 
be acted on at stockholder meetings and limit the right to call special meetings of stockholders to the Chairman of our 
board, our Chief Executive Officer, our Board acting pursuant to a resolution adopted by a majority of directors or our 
Secretary upon the written request of stockholders entitled to cast not less than 35% of all the votes entitled to be cast 
at such meeting. 
  
In addition, because we are incorporated in Delaware, we are governed by the provisions of Section 203 of the Delaware 
General Corporation Law, which may, unless certain criteria are met, prohibit large stockholders, in particular those owning 
15% or more of our outstanding voting stock, from merging or combining with us for a prescribed period of time. 
 
General Risk Factors 
 
Our stock price could fluctuate for numerous reasons, including variations in our results. 
 
Our quarterly operating results have fluctuated in the past and may do so in the future. Accordingly, we believe that 
period-to-period comparisons of our results of operations may be the best indicators of our business. You should not rely upon 
the results of one quarter as an indication of future performance. Our revenues and operating results may fall below the 
expectations of securities analysts or investors in any future period. Our failure to meet these expectations may cause the 
market price of our common stock to decline, perhaps substantially. Our quarterly revenues and operating results may vary 
depending on a number of factors, including those listed previously under “—Risks Related to Our Business.” In addition, the 
price of our 
common stock is subject to general economic, market, industry, and competitive conditions, the risk factors discussed herein 
and numerous other conditions outside of our control. 
 

Table of Contents 
34 
Deteriorations in economic conditions in certain markets or other factors may cause us to recognize additional impairment 
charges for our goodwill. 
 
During the year ended December 31, 2023, we recognized goodwill impairment charges of $13.8 million within the 
International reporting units. Future deterioration in industry or economic conditions in which we operate, including increased 
inflationary costs, costs associated with proposed tariffs or other trade restrictions, energy costs, labor costs, social pressures 
and disruptions in Europe, the Middle East or elsewhere as a result of the war between Russia and Ukraine and the conflict 
between Israel and Hamas, disruptions to our business, not effectively integrating acquired businesses, macroeconomic factors 
or other factors, may cause impairment charges to our goodwill in future periods.  
  
We are subject to privacy and data security/protection laws in the jurisdictions in which we operate and may be exposed to 
substantial costs and liabilities associated with such laws and regulations. 
 
The regulatory environment surrounding information security and privacy is increasingly demanding, with frequent imposition 
of new and changing requirements. The European Union's General Data Protection Regulation (“GDPR”), which became 
effective in May 2018, imposed significant new requirements on how companies process and transfer personal data, as well as 
significant fines for non-compliance. In addition to GDPR, many states in the U.S. and provinces in Canada have enacted, or 
are considering, data privacy requirements similar to GDPR, and thus we will need to ensure our procedures comply with these 
various state and provincial laws. Compliance with changes in privacy and information security laws and standards may result 
in significant expense due to increased investment in technology and the development of new operational processes, which 
could have a material adverse effect on our financial condition and results of operations. In addition, the payment of potentially 
significant fines or penalties in the event of a breach of privacy and information security laws, as well as the negative publicity 
associated with such a breach, could damage our reputation and adversely impact product demand and customer relationships. 
 
If we lose key members of our senior management team upon whom we are dependent, we may be less effective in managing 
our operations and may have more difficulty achieving our strategic objectives. 
  
Our future success depends to a considerable degree upon the availability, contributions, vision, skills, experience and effort of 
our senior management team. We have in place various compensation programs, such as an annual cash incentive program, 
equity incentive program and a severance policy, each designed to incentivize and retain our key senior managers. At this time, 
we do not have any reason to believe that we may lose the services of any of these key persons in the foreseeable future and we 
believe our compensation programs will help us retain these individuals. However, an unplanned loss or interruption of the 
service of numerous key members of our senior management team could harm our business, financial condition and results of 
operations and could significantly reduce our ability to manage our operations and implement our strategy. 
 
Intellectual property may impact our business and results of operations. 
  
Our ability to compete effectively depends in part upon the maintenance and protection of the intellectual property related to 
our asset protection solutions. Patent protection is unavailable for certain aspects of the technology and operational processes 
important to our business and any patent or patent applications, trademarks or copyrights held by us or to be issued to us, may 
not adequately protect us. To date, we have relied principally on copyright, trademark and trade secrecy laws, as well as 
confidentiality agreements and licensing arrangements, and more recently, patent protection, to establish and protect our 
intellectual property. However, we have not obtained confidentiality agreements from all our customers. Although we obligate 
our employees to confidentiality, we cannot be certain that these obligations will be honored or enforceable in all 
circumstances.

Social, political and economic changes or instability, or other circumstances beyond our control could affect our business 
operations. 
 
Our business may be adversely affected by social, political and economic instability, unrest or disruption, including legal, 
regulatory and policy changes by a new presidential administration in the U.S., protests, demonstrations, strikes, riots, civil 
disturbance, disobedience, insurrection, or social and other political unrest. Such events may result in restrictions, curfews or 
other actions and give rise to significant changes in regional and global economic conditions and cycles, which may adversely 
affect our financial condition and operations. 
 
Changes in federal policy, including tax policies, and at regulatory agencies occur over time through policy and personnel 
changes following elections, which can lead to changes involving the level of oversight and focus on certain industries and 
corporate entities. The nature, timing, and economic and political effects of potential changes to the current legal and regulatory 
frameworks affecting the industries in which we operate remain highly uncertain. Additionally, changes in federal policy that 
affect the geopolitical landscape, such as the imposition of tariffs and changes to U.S. trade policy, have, and could in the 
future, lead to adverse effects on the U.S. domestic economy and our business operations. 
  
We may require additional capital to support business growth, which might not be available. 
  
We intend to continue making investments to support our business growth and may require additional funds to respond to 
business challenges or opportunities, including the need to develop new, or enhance our current, asset protection solutions, 
enhance our operating infrastructure or acquire businesses and technologies. Accordingly, we may need to engage in equity or 
debt financings to secure additional funds. If we raise additional funds through further issuances of equity or convertible debt 
securities, our current stockholders could suffer significant dilution, and any new equity securities we issue could have rights, 
preferences and privileges superior to those of holders of our common stock. Our current credit facility meets our current needs, 
except that due to our current debt levels, the facility limits our ability to make acquisitions without the banks' approval until 
our debt ratio improves. If we were to secure other debt financing in the future, it could involve restrictive covenants relating to 
our capital-raising activities and other financial and operational matters, which may make it more difficult for us to obtain 
additional capital and to pursue business opportunities, including potential acquisitions. In addition, no assurance can be given 
that adequate or acceptable financing will be available to us, in which case we may not be able to grow our business, including 
through acquisitions, or respond to business challenges.

ITEM 1C.                                               CYBERSECURITY 
  
We prioritize the protection of our data assets, the private data of our employees, customers, and vendors, and personal 
information. To assess, identify, and manage the risks of cybersecurity threats to our information systems and the associated 
costs, we maintain a robust cybersecurity program that is integrated into the Company’s overall Enterprise Risk Management 
strategy. We understand that threats from hackers and other cyber criminals continues to adapt and become more sophisticated, 
and so must our response to these threats. 
 
Governance 
 
Our Board is responsible for oversight of our cybersecurity program. The Audit Committee, Enterprise Risk Committee, and 
the Information Technology Leadership Team support the Board in the oversight of our information security program and are 
focused on cybersecurity and data privacy risk, including compliance with all applicable laws and regulations, incident 
response planning, timely identification and assessment of incidents, incident recovery and business continuity considerations. 
Our cybersecurity risk management and internal controls program are aligned to ISO27001 Standards and the National Institute 
of Standards and Technology (NIST) framework. 
 

Table of Contents

As part of our cybersecurity program management activities and our continuing efforts to evaluate and enhance the 
effectiveness of our cybersecurity policies and procedures, we actively engage internal and prominent external experts, as well 
as industry participants. Our cybersecurity program is managed by the Chief Information Officer who has biannual meetings 
with the Audit Committee and provides periodic reports and updates concerning our cybersecurity program to our Chief 
Executive Officer and other members of our senior management, as appropriate. These reports include updates on our cyber 
risk and threats, the status of projects to strengthen our information network and data security, assessments of our information 
security program, and the emerging threat landscape. We have established governance committees to provide us with 
cybersecurity oversight with supportive roles to advance the effectiveness of our cybersecurity program. The Chief Information 
Officer has over 20 years of IT leadership and cybersecurity experience, and the Information Technology Leadership Team 
overall has a combined fifteen years of cybersecurity experience. The Chief Information Officer and members of the 
Information Technology Leadership Team maintain industry recognized credentials relevant to their roles and stay informed on 
the latest trends and technologies. 
 
The Chief Information Officer manages both an Information Security team and an IT Risk team within the Department of 
Information Technology. The IT Risk team works closely with our Data Privacy Officer for governance and compliance related 
to regulations and frameworks for data classification, data privacy, handling of private data and controlled unclassified 
information, and internal policies and procedures. The Cyber Security team is responsible for identifying and implementing 
technologies to mitigate IT risk, enhance data security, and identify and defend against attacks. Both teams work closely 
together to establish the cybersecurity policies for the Company, evaluate the current risk profile, and to prevent, investigate, 
mitigate, and remediate any cyber-attacks on the Company. 
 
Risk Management and Strategy 
 
The IT Risk team uses an asset-based risk approach for evaluating cybersecurity risks and appropriate risk mitigation. All IT 
assets are reviewed against a broad range of risks twice a year and are evaluated for likelihood of occurrence and impact should 
they occur. These risks are then mapped to our global inventory of systems and the type of data as well as the number of 
systems to which a risk applies are evaluated. These factors are used to determine a risk score for each of the reviewed risks, 
and mitigations are subsequently applied to reduce those risk scores to determine the areas of focus for increasing mitigations.  
This exercise is logged biannually to monitor improvement.  
 
We have several physical, automated, and administrative controls in place to mitigate the success and extent of any cyber 
breaches. Our controls are designed to require review of tasks which may occur in the normal course of business but are also 
common vectors of attack. Automated controls are implemented in all cases where one is feasible, and in other cases standard 
procedures or documented instructions are in place to ensure that actions are proper and approved before they occur. 
 
Policies related to cybersecurity risks are documented, reviewed annually, and published internally, which define the correct 
processes for identifying, containing, remediating, and responding to cybersecurity incidents. Our data protection policies 
define the establishment of the classification of types of data. Based upon this data classification, we determine an incident’s 
materiality and establish the appropriate response, the incident management team, and the communications required to be 
distributed to third parties. Incident management policies are in place to establish the proper communication channels and 
responsible parties for different levels of materiality of an incident. We practice these policies and procedures in a tabletop or 
simulated fashion multiple times annually.  
 
Each employee plays a role in safeguarding our data assets, and the protection of our data is ingrained in every employee’s day 
to day activities. Employees must participate in annual cyber security training. Simulated testing occurs multiple times 
throughout the year, including drop testing and SPAM / PHISHING campaigns, and the results are tracked for compliance and 
we address any weaknesses identified in such trainings and testings as necessary. 
 
The Information Security team performs internal threat hunting, vulnerability scanning, log aggregation, and identity 
monitoring on an on-going basis. Web site, code, and configuration vulnerability scans are performed as necessary to ensure 

Table of Contents 
37 
that changes do not introduce vulnerabilities into our systems. Information Security and IT Risk personnel receive regular 
training to ensure these individuals have up-to-date expert knowledge. 
 
To supplement our cybersecurity risk assessment, identification, management, and mitigation efforts, we engage third party 
cyber security experts. Cyber security assessments are performed at least annually, results are documented and reviewed, and 
mitigation plans are put in place to reduce any threats identified. The classification of data processed by any system is 
considered when implementing mitigations. 
 
We recognize the importance of overseeing and identifying material risks from cybersecurity threats associated with our use of 
third-party vendors. We perform a thorough review of the cyber security measures in place, including any documented third-
party audits, for any partners who process our data. Sign-off is required by the Information Security team before agreements 
can be put in place. 
 
We believe that our current preventative actions and response activities provide adequate measures of protection against 
security breaches and generally reduce our cybersecurity risks. However, cybersecurity threats are constantly evolving, are 
becoming more frequent and more sophisticated and are being made by groups of individuals with a wide range of expertise 
and motives, which increases the difficulty of detecting and successfully defending against them. While we have implemented 
measures to safeguard our operational and technology systems and have established a culture of continuous learning, 
monitoring and improvement, the evolving nature of cybersecurity attacks and vulnerabilities means that these protections may 
not always be effective. However, as of the date of this Annual Report, management has determined that none of the 
cybersecurity attacks that we have experienced has resulted in a material impact on our financial condition, results of operations 
or business strategy. In addition, as of the date of this Annual Report, we are not aware of any risks from cybersecurity threats 
that have materially affected or are reasonably likely to materially affect us, including our business strategy, results of 
operations and financial condition. 
 
For additional information regarding how cybersecurity threats have affected or are reasonably likely to materially affect our 
business strategy, results of operations or financial condition, see Part I, Item 1A, “Risk Factors—Risks Related to Our 
Business—We face risks regarding our information technology and security”. 
 
  
ITEM 2.                                               PROPERTIES 
  
As of December 31, 2024, we operated approximately 105 facilities in 11 countries, with our corporate headquarters located in 
Princeton Junction, New Jersey. Our headquarters in Princeton Junction is our primary location, where most of our 
manufacturing and research and development is conducted. While we lease most of our facilities, as of December 31, 2024, we 
owned properties located in Monroe, North Carolina; Trainer, Pennsylvania; LaPorte, Texas; Burlington, Washington; 
Evanston, Wyoming; and Jonquiere, Quebec, Canada. Our North America segment utilizes approximately 71 facilities 
throughout North America (including Canada and Mexico). Our Products and Systems segment’s primary location is in our 
Princeton Junction, New Jersey facility. Our International segment has approximately 30 facilities including locations in 
Belgium, Brazil, France, Germany, Greece, India, the Netherlands and the United Kingdom. We believe that all of our facilities 
are well maintained and are suitable and adequate for the foreseeable future. 
  
ITEM 3.                                               LEGAL PROCEEDINGS 
  
We are subject to periodic legal proceedings, investigations and claims that arise in the ordinary course of business. See “Legal 
Proceedings and Government Investigations - Litigation and Commercial Claims” in Note 18-Commitments and Contingencies

Other Updates 
 
We are currently unable to predict with certainty the effects that inflationary pressures and the ongoing war between Russia and 
Ukraine war may have on our business, results of operations or liquidity or in other ways which we cannot yet determine. Our 
European operations have experienced increased costs associated with higher energy costs during 2023, among others, due in 
part to the on-going war between Russia and Ukraine. We may also experience increased costs associated with tariffs or trade 
barriers (including recent U.S. tariffs imposed or threatened to be imposed on China, Canada, Mexico and other countries and 
any retaliatory actions taken by such countries). We will continue to monitor market conditions and respond accordingly. 
 
  
Overview 
 
We are a leading "one source" multinational provider of integrated technology-enabled asset protection solutions, helping to 
maximize the safety and operational uptime for civilization’s most critical industrial and civil assets. 
 
Backed by an innovative, data-driven asset protection portfolio, proprietary technologies, strong commitment to Environmental, 
Social, and Governance ("ESG") initiatives, and a decades-long legacy of industry leadership, the Company helps customers 
with asset-intensive infrastructure in the oil and gas, petrochemical, aerospace and defense, renewable and nonrenewable 
power, civil infrastructure, and manufacturing industries towards achieving operational and environmental excellence. By 
supporting these customers that help fuel our vehicles and power our society; inspecting components that are trusted for 

Table of Contents 
41 
commercial, defense, and space craft; building real-time monitoring equipment to enable safe travel across bridges; and helping 
to propel sustainability, the Company helps the world at large.  
 
The Company enhances value for its customers by integrating asset protection throughout supply chains and centralizing 
integrity data through a suite of Industrial IoT-connected digital software and monitoring solutions. The Company’s core 
capabilities also include non-destructive testing ("NDT") field and in-line inspections enhanced by advanced robotics, 
laboratory quality control and assurance testing, sensing technologies and NDT equipment, asset and mechanical integrity 
engineering services, and light mechanical maintenance and access services.  
 
Our operations consist of three reportable segments: North America (which we previously referred to as our Services segment), 
International, and Products and Systems. 
  
• 
North America provides asset protection solutions with the largest concentration in the United States, followed by 
Canada, consisting primarily of NDT, inspection, mechanical and engineering services that are used to evaluate the 
structural integrity and reliability of critical energy, industrial and public infrastructure and commercial aerospace 
components. A majority of data analytical solutions revenues are generated by this segment. 
 
• 
International offers services, products and systems similar to those of the other segments to select markets within 
Europe, the Middle East, Africa, Asia and South America, but not to customers in China and South Korea, which are 
served by the Products and Systems segment. 
 
• 
Products and Systems designs, manufactures, sells, installs and services the Company’s asset protection products and 
systems, including equipment and instrumentation, predominantly in the United States. 
 
Given the role our solutions play in enhancing the safe and efficient operation of infrastructure, we have historically provided a 
majority of our solutions to our customers on a regular, recurring basis. We perform these services largely at our customers’ 
facilities, while primarily servicing our aerospace customers at our network of state-of-the-art, in-house laboratories. These 
solutions typically include NDT and inspection services, and can also include a wide range of mechanical services, including 
heat tracing, pre-inspection insulation stripping, coating applications, re-insulation, engineering assessments and long-term 
condition-monitoring. Under this business model, many customers outsource their inspection to us on a “run and maintain” 
basis. We have established long-term relationships as a critical solutions provider to many of the leading companies with asset-
intensive infrastructure in our target markets. These markets include companies in the oil and gas, aerospace and defense, 
industrials, power generation and transmission (including alternative and renewable energy), other process industries and 
infrastructure, research and engineering and other industries. 
 
We have focused on providing our advanced asset protection solutions to our customers using proprietary, technology-enabled 
software and testing instruments, including those developed by our Products and Systems segment. We have made numerous 
acquisitions in the past in an effort to grow our base of experienced, certified personnel, expand our service lines and technical 
capabilities, increase our geographical reach, complement our existing offerings, and leverage our fixed costs. We have 
increased our capabilities and the size of our customer base through the development of applied technologies and managed 
support services, organic growth and the integration of acquired companies. These acquisitions have provided us with 
additional service lines, technologies, resources and customers which we believe enhance our advantages over our competition. 
 
We believe long-term growth can be realized in our target markets. Our level of business and financial results are impacted by 
world-wide macro- and micro-economic conditions generally, as well as those within our target markets. Among other things, 
we expect the timing of our oil and gas customers' inspection expenditures to be impacted by oil price fluctuations.  
 
We have continued providing our customers with an innovative asset protection software ecosystem through our OneSuite 
platform. The software platform offers functions of our software and services brands as integrated apps on a cloud environment. 
OneSuite serves as a single access portal for customers' data activities and provides access to 90 plus applications being offered 
on one centralized platform.

2024 Developments 
 
The Company provides products and services to countries throughout the Middle East, where lawfully permitted, and in 
accordance with United States regulations. We continue to monitor the on-going conflicts throughout the Middle East.  These 
conflicts caused disruptions in the Company's European operations in 2023 with increased costs associated with higher energy 
costs, amongst others. These disruptions have largely subsided in 2024, and the Company will continue to monitor market 
conditions and respond accordingly. 
 
Our cash position and liquidity remain strong. As of December 31, 2024, our cash and cash equivalents balance was 
approximately $18.3 million and our Credit Agreement provides us with significant liquidity. 
 
In April 2021, the Biden Administration announced aggressive initiatives to battle climate change, which includes potential 
plans for a significant reduction in the use of fossil fuels and a transition to electric vehicles and increased use of alternative 
energy. Any legislation or regulations that may be adopted to implement these measures may negatively impact our customers 
in the oil and gas market over the long-term, which presently is our largest market, although this initiative will likely benefit the 
alternative energy market, such as wind energy, for which we provide products and services. At this time, it is difficult to 
determine the magnitude and timing of the impact that climate change initiatives and legislation, if any, will have on these 
markets and the resulting impact on our business and operational results. 
 
The Company is currently unable to predict with certainty the overall impact that the factors discussed above and the effect of 
continuing inflationary pressures or increased costs due to tariffs and trade barriers may have on its business, results of 
operations or liquidity or in other ways which the Company cannot yet determine. The Company's European operations are 
currently experiencing higher energy costs, among other increased costs, due in part to the on-going war between Russia and 
Ukraine and the conflict in the Middle East between Israel and Hamas. The Company will continue to monitor market 
conditions and respond accordingly. Refer to Item 1A. Risk Factors in Part I of our 2024 Annual Report. 
 
On December 5, 2024, our Board of Directors (the “Board”), in furtherance of its management succession planning, appointed 
Natalia Shuman, as the Company’s President and Chief Executive Officer, and Manny Stamatakis will continue as the 
Executive Chairman of the Company effective as of January 1, 2025. Mr. Stamatakis served as our Chairman of the Board and 
Interim President and Chief Executive Officer until December 31, 2024.  
 
On December 12, 2024, we announced the appointment of Hani Hammad to the position of Executive Vice President and Chief 
Operating Officer effective as of January 1, 2025. 
 
On February 6, 2025, we announced the passing of Dr. Sotirios J. Vahaviolos, our founder and Chairman Emeritus.  
 
On February 7, 2025, we announced the termination of John A. Smith as our Executive Vice President and President of 
Services. 
 
Note about Non-GAAP Measures 
  
The Company prepares its consolidated financial statements in accordance with U.S. GAAP.  In this MD&A under the heading 
"Income (loss) from Operations", the non-GAAP financial performance measure "Income (loss) from operations before special 
items” is used for each of our three operating segments, the "Corporate" segment and for the "Total Company", with tables 
reconciling the "Income (loss) from operations before special items" to "Income (loss) from operations", which is a financial 
measure under GAAP. This presentation excludes from "Income (loss) from Operations" (a) transaction expenses related to 
acquisitions, such as professional fees and due diligence costs, (b) the net changes in the fair value of acquisition-related 
contingent consideration liabilities, (c) impairment charges, (d) reorganization and other costs, which includes items such as 
severance, labor relations matters and asset and lease termination costs and (e) other special items. These adjustments have been 
excluded from the GAAP measure because these expenses and credits are not related to our or any individual segment's core 

Table of Contents 
43 
business operations. The acquisition related costs and special items can be a net expense or credit in any given period. Our 
management uses this non-GAAP measure as a measure of operating performance and liquidity to assist in comparing 
performance from period to period on a consistent basis, as a measure for planning and forecasting overall expectations and for 
evaluating actual results against such expectations. We believe investors and other users of our financial statements benefit from 
the presentation of this non-GAAP measure in evaluating our performance.  Income (loss) before special items excludes the 
identified adjustments, which provides additional tools to compare our core business operating performance on a consistent 
basis and measure underlying trends and results in our business.  Income (loss) before special items is not used to determine 
incentive compensation for executives or employees, nor is it a replacement for the reported GAAP financial performance 
and/or necessarily comparable to the non-GAAP financial measures of other companies. Any measure that eliminates the 
foregoing items has material limitations as a performance or liquidity measure and should not be considered alternatives to net 
income (loss) or any other measures derived in accordance with GAAP. Because Income (loss) from operations before special 
items may not be calculated in the same manner by all companies, this measure may not be comparable to other similarly titled 
measures used by other companies.

In presenting the allocation of revenues by type in the table above, management makes certain assumptions in its allocation of 
revenue from laboratories that provide more than one type of service. The allocation methodology and assumptions made are 
consistent for the years presented. 
 
Field Services revenue is comprised of revenue derived primarily by technicians performing asset inspections and maintenance 
services for our customers at locations other than our properties. Field Services revenue increased $32.4 million, or 6.9%, for 
the twelve months ended December 31, 2024 as compared to the twelve months ended December 31, 2023. The increase was 
due to increased sales volume in our oil and gas and power generation and transmission end markets for our North America and 
International segments.

Shop Laboratory revenue is comprised of quality assurance inspections of components and materials at our in-house laboratory 
facilities. Shop Laboratory revenue increased $6.4 million, or 11.0%, for the twelve months ended December 31, 2024 as 
compared to the twelve months ended December 31, 2023. The increase was due to increased sales volume related to our 
commercial aerospace and industrials end markets. 
 
Data Analytical Solutions revenue is comprised of revenue derived from data software sales & subscriptions, implementation 
services and analytics that offer insights and recommendations to improve asset integrity. Data Analytical Solutions revenue is 
derived from work performed by our employees in our facilities, or at customer locations, using our proprietary portfolio of 
software applications. Data Analytical Solutions revenue decreased $3.3 million, or 4.6%, for the twelve months ended 
December 31, 2024 as compared to the twelve months ended December 31, 2023. The decrease was due primarily to decreased 
sales volume within PCMS, Onstream and other Data Analytical Solutions offerings within our North America segment.  
 
Other revenue are comprised of locations that perform both asset inspection services and testing of components and materials at 
our in-house laboratories. Other revenue decreased $11.3 million, or 10.8%, for the twelve months ended December 31, 2024 as 
compared to the twelve months ended December 31, 2023. Other revenue for the year ended December 31, 2024 decreased 
primarily due to decreased sales within the other end markets within the North America and International segments as 
compared to the prior year period.

Total Company income from operations (GAAP) increased by $41.7 million, or 2,191.7% compared to the year ended 
December 31, 2023. Total company income before special items (non-GAAP) increased by $21.0 million or 83.1% compared 
with the year ended December 31, 2023. Operating expenses, excluding special items (non-GAAP), as a percentage of revenue, 
was 22.9% for the year ended December 31, 2024 compared to 25.3% for the year ended December 31, 2023. The primary 
driver for the increase in Total Company income before special items was increased sales in 2024 compared to 2023. Total

Company income before special items as a percentage of revenue increased by 270 basis points to 6.3% for the year ended 
December 31, 2024, from 3.6% for the year ended December 31, 2023. Our discussion below is qualified by the unknown 
impact that the Russia - Ukraine war will continue to have on our business and the economy in general, including the resulting 
economic disruption. Refer to Item 1A. Risk Factors in Part I of this Annual Report for further discussion. 
  
Interest Expense 
  
Interest expense was $17.1 million and $16.8 million for the years ended December 31, 2024 and December 31, 2023, 
respectively. The increase was due to increased interest rates in the current period. 
 
Income Taxes 
 
Our effective income tax rate was approximately 21.8% for the year ended December 31, 2024, compared to 6.5% for the year 
ended December 31, 2023.  The increase in effective tax rate was primarily driven by an impairment of $13.8 million 
impairment in year ended December 31, 2023, partially offset by the releasing of valuation allowance of $1.8 million. 
 
On December 27, 2020, the United States enacted the Consolidated Appropriations Act, 2021, (the "Appropriations Act") an 
additional stimulus package providing financial relief for individuals and small business. The Appropriations Act contains a 
variety of tax provisions, including full expensing of business meals in 2021 and 2022, and expansion of the employee retention 
tax credit. We are currently evaluating the impact of this guidance on our consolidated financial position, results of operations, 
and cash flows, but do not expect it to have a material impact. 
 
On August 19, 2022, the United States enacted the Inflation Reduction Act, (the "Inflation Act"), a package intended to reduce 
inflation. The Inflation Act contains a variety of tax provisions, including a 15% corporate minimum tax, a tax on stock 
repurchases, and various tax credit opportunities. We evaluated the impact of this guidance on our consolidated financial 
position, results of operations, and cash flows, and do not expect it to have a material impact. 
 
Income tax expense varies as a function of pre-tax income and the level of non-deductible expenses, such as certain amounts of 
meals and entertainment expense, valuation allowances, and other permanent differences. It is also affected by discrete items 
that may occur in any given year but are not consistent from year to year. Our effective income tax rate may fluctuate over the 
next few years due to many variables including the amount and future geographic distribution of our pre-tax income, changes 
resulting from our acquisition strategy, and increases or decreases in our permanent differences. 
 
Liquidity and Capital Resources 
  
Overview 
  
We have funded our operations from cash provided from operations, bank borrowings and lease financings. Management 
believes that our existing cash and cash equivalents, anticipated cash flows from operating activities, and available borrowings 
under our Credit Agreement will be more than sufficient to meet anticipated cash needs over the next 12 months and for the 
foreseeable future. We generated operating cash flows of $50.1 million and $26.7 million for the years ended December 31, 
2024 and 2023, respectively. Capital expenditures for the purchase of property, plant and equipment and of intangible assets 
was $23.0 million and $23.6 million for the years ended December 31, 2024 and 2023, respectively.

Cash Flows from Operating Activities 
 
Cash provided by operating activities for the year ended December 31, 2024 was $50.1 million, an increase of $23.4 million 
from the prior year period. The increase was mainly attributable to movements in working capital driven primarily by an 
increase in operating results and an increase in net accounts receivable collections in the current year as compared to the prior 
year. 
 
Cash Flows from Investing Activities 
 
Net cash used in investing activities for the year ended December 31, 2024 was $21.4 million, a decrease of $0.8 million used 
in investing activities from the prior year period. The Company used $0.7 million less cash for purchases of property, plant and 
equipment and intangible assets in 2024 compared to 2023.  
 
Cash Flows from Financing Activities 
  
Net cash used in financing activities for the year ended December 31, 2024 was $27.4 million, compared to $7.7 million for the 
year ended December 31, 2023. Net repayment of our revolving credit facility and term loan was approximately $19.5 million 
higher compared to 2023. In addition, for the year ended December 31, 2024, we incurred approximately $0.3 million less in 
taxes paid related to net share settlement of share-based awards than the prior period. 
 
Effect of Exchange Rate Changes on Cash and Cash Equivalents 
  
The effect of exchange rate changes on our cash and cash equivalents was a decrease of $0.7 million for the year ended 
December 31, 2024, compared to an increase of $0.2 million for the year ended December 31, 2023. The primary driver of the 
change was foreign currency fluctuations during the year ended December 31, 2024 related to the Euro and the US Dollar. 
 
Cash Balance and Credit Facility Borrowings 
  
As of December 31, 2024, we had cash and cash equivalents totaling $18.3 million and available borrowing capacity of up to 
$119.2 million under our Credit Agreement. Borrowings of $167.2 million and letters of credit of $3.1 million were outstanding 
under the Credit Agreement at December 31, 2024. We finance our operations primarily through our existing cash balances, 
cash collected from operations, bank borrowings and lease financing. We believe these sources are sufficient to fund our 
operations for the foreseeable future. As of December 31, 2024, we were in compliance with the terms of the Credit Agreement 
and will continuously monitor our compliance with the covenants contained in the Credit Agreement.  
 
The terms of our Credit Agreement are described in Note 11-Long-Term Debt of the notes to the consolidated financial 
statements, under the heading "Senior Credit Facility".

Liquidity and Capital Resources Outlook 
  
Future Sources of Cash 
  
We expect our future sources of cash to include cash flow generated from our operating activities and borrowings under our 
Credit Agreement. Our revolving credit facility is available for cash advances required for working capital and for letters of 
credit to support our operations. Acquisitions, if any, are funded through available cash and borrowings under the Credit 
Agreement.  
  
Future Uses of Cash 
  
We expect our future uses of cash will primarily be for repayment of debt, purchases or manufacture of field-testing equipment 
to support growth, additional investments in technology and software products and the replacement of existing assets and 
equipment used in our operations. We often make purchases to support new sources of revenues, particularly in our North 
America segment. In addition, we annually fund a certain amount of replacement equipment, including a portion of our fleet 
vehicles. We historically spend approximately 2% to 3% of our total revenues on capital expenditures, excluding acquisitions, 
and expect to fund these expenditures through a combination of cash and lease financing. Our cash capital expenditures, 
excluding acquisitions, for each of the years ended December 31, 2024 and 2023 were approximately 3.2% and 3.4% of 
revenues, respectively. We continue to take steps to reduce spending and preserve cash. 
 
Our Credit Agreement does not limit our ability to acquire other businesses or companies except for certain provisions as 
described within Note 11-Long-Term Debt of the notes to the consolidated financial statements. Our future capital spending 
may increase as we pursue growth opportunities and acquire additional equipment to meet or pursue business opportunities. 
Other investments in infrastructure, training and software may also be required to match our growth, but we plan to continue 
using a disciplined approach to building our business. In addition, we will use cash to fund our operating leases, finance leases, 
long-term debt repayments and various other obligations as they arise as noted within Note 11-Long-Term Debt and Note 17- 
Leases of the notes to the consolidated financial statements.  
  
We also expect to use cash to support our working capital requirements for our operations, particularly in the event of further 
growth and due to the impacts of seasonality on our business. Our future working capital requirements will depend on many 
factors, including the rate of our revenue growth, our introduction of new solutions and enhancements to existing solutions and 
our expansion of sales and marketing and product development activities. To the extent that our cash and cash equivalents and 
future cash flows from operating activities are insufficient to fund our future activities, we may need to raise additional funds 
through bank credit arrangements, or public or private equity, or debt financings. We also may need to raise additional funds in 
the event we determine in the future to effect one or more acquisitions of businesses, technologies or products that will 
complement our existing operations. In the event additional funding is required, we may not be able to obtain bank credit 
arrangements or effect an equity or debt financing on acceptable terms. 
 
Off-Balance Sheet Arrangements 
  
During the years ended December 31, 2024 and 2023, we did not have any relationships with unconsolidated entities or 
financial partnerships, such as entities often referred to as structured finance or special purpose entities, which would have been 
established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes.

Critical Accounting Policies and Estimates 
  
The preparation of financial statements in accordance with U.S. GAAP requires that we make estimates and assumptions that 
affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of financial 
statements and the reported amounts of revenues and expenses during the reporting period. We have established policies and 
control procedures intended to ensure that estimation methods, including any judgments made as part of such methods, are 
well-controlled, independently reviewed and applied consistently from period to period. The accounting policies that we believe 
require more significant estimates and assumptions include revenue recognition, acquisitions, long-lived assets and goodwill. 
We base our estimates and assumptions on historical experience, known or expected trends and various other assumptions that 
we believe to be reasonable. As future events and their effects cannot be determined with precision, actual results could differ 
significantly from these estimates, which may cause our future results to be significantly affected. 
  
We believe that the following critical accounting policies comprise the more significant estimates and assumptions used in the 
preparation of our consolidated financial statements. 
  
Revenue Recognition 
  
The majority of our revenues are derived from providing services on a time and material basis and are short-term in nature. We 
account for revenue in accordance with Accounting Standards Codification ("ASC") Topic 606, Revenue from Contracts with 
Customers. 
 
Performance Obligations 
 
A performance obligation is a promise in a contract to transfer a distinct good or service to the customer, and is the unit of 
account in ASC Topic 606. A contract’s transaction price is allocated to each distinct performance obligation and recognized as 
revenue when, or as, the performance obligation is satisfied. The majority of our contracts have a single performance obligation 
as the promise to transfer the individual goods or services is not separately identifiable from other promises in the contracts and 
is, therefore, not distinct. We provide highly integrated and bundled inspection services to our customers. Some of our contracts 
have multiple performance obligations, most commonly due to the contract providing both goods and services. For contracts 
with multiple performance obligations, we allocate the contract’s transaction price to each performance obligation using our 
best estimate of the standalone selling price of each distinct good or service in the contract. The primary method used to 
estimate standalone selling price is a relative selling price based on price lists. 
 
Contract modifications are not routine in the performance of our contracts. Generally, when contracts are modified, the 
modification is to account for changes in scope to the goods and services that are provided. In most instances, contract 
modifications are for goods or services that are distinct, and, therefore, are accounted for as a separate contract. 
 
Our performance obligations are satisfied over time as work progresses or at a point in time. The majority of our revenue 
recognized over time as work progresses is related to our service deliverables, which includes providing testing, inspection and 
mechanical services to our customers. Revenue is recognized over time based on time and material incurred to date which best 
portrays the transfer of control to the customer. We also utilize an available practical expedient that provides for revenue to be 
recognized in an amount that corresponds directly with the value to the customer of the entity’s performance completed to date.  
Fixed fee arrangements are determined based on expected labor, material and overhead to be consumed on fulfillment of such 
services. Revenue is recognized on a cost-to-cost method tracked on an input basis.  
 
The majority of our revenue recognized at a point in time is related to product sales when the customer obtains control of the 
asset, which is generally upon shipment to the customer. Contract costs include labor, material and overhead. 
 
We expect any significant remaining performance obligations to be satisfied within one year. 
 
Contract Estimates 

Table of Contents 
52 
 
The majority of our revenues are short-term in nature. We have many Master Service Agreements ("MSAs") that specify an 
overall framework and contract terms, where we and our customers agree upon services or products to be provided. The actual 
contracting to provide services or furnish products are triggered by a work order, purchase order, or some similar document 
issued pursuant to an MSA which sets forth the scope of services and/or identifies the products to be provided. From time to 
time, we may enter into long-term contracts, which can range from several months to several years. Revenue on such long-term 
contracts is recognized as work is performed based on total costs incurred to date in relation to the total estimated costs for the 
performance of the contract at completion. This includes contract estimates of costs to be incurred for the performance of the 
contract. Cost estimation is based upon the professional knowledge and experience of our project managers, engineers and 
financial professionals. Factors that are considered in estimating the work to be completed include the availability of materials, 
the effect of any delays in our project performance and the recoverability of any claims. Whenever revisions of estimates, 
contract costs and/or contract values indicate that the contract costs will exceed estimated revenues, thus creating a loss, a 
provision for the total estimated loss is recorded in that period. 
  
Long-Lived Assets 
  
We perform a review of long-lived assets (or asset groups) for impairment when events or changes in circumstances indicate the 
carrying value of such assets may not be recoverable. If an indication of impairment is present, we compare the estimated 
undiscounted future net cash flows to be generated by the asset (or asset group) to its carrying amount. If the undiscounted 
future net cash flows are less than the carrying amount of the asset (or asset group), we record an impairment loss equal to the 
excess of the asset’s carrying amount over its fair value. We estimate fair value based on valuation techniques such as a 
discounted cash flow analysis or a comparison to fair values of similar assets. As of December 31, 2024 and December 31, 
2023, we had $80.9 million and $81.0 million in net property, plant and equipment, respectively, and $39.7 million and $44.0 
million in intangible assets, net, respectively. 
  
Goodwill 
 
Goodwill represents the excess purchase price of acquired businesses over the fair values attributed to underlying net tangible 
assets and identifiable intangible assets. We test goodwill for impairment at a “reporting unit” level (which for us is represented 
by (i) our North America segment, (ii) our Products and Systems segment, (iii) the European component of our International 
segment and (iv) the Brazilian component of our International segment). Our annual impairment test is conducted on the first 
day of our fourth quarter, which is October 1. Goodwill is also tested for impairment whenever an event occurs or 
circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. 
 
In testing for goodwill impairment, we have the option to first assess qualitative factors to determine whether the existence of 
events or circumstances lead to a determination that it is more likely than not that the fair value of a reporting unit is less than 
its carrying amount. If, after assessing the totality of events and circumstances, we conclude that it is not more likely than not 
that the fair value of a reporting unit is less than its carrying amount, then performing a quantitative impairment test is not 
necessary. If we conclude otherwise, we are required to perform a quantitative impairment test.  
 
An impairment will be recorded in the amount that the fair value is less than the carrying value. We consider the income and 
market approaches to estimating the fair value of our reporting units, which requires significant judgment in evaluation of 
economic and industry trends, estimated future cash flows, discount rates and other factors. Sustained declines in our stock 
price and related market capitalization could impact key assumptions in the overall estimated fair values of our reporting units 
and could result in non-cash impairment charges that could be material to our consolidated balance sheet or results of 
operations.  
 
During the third quarter of 2023, a triggering event was identified within the Company's reporting units within the International 
segment due to decreased gross margin in the current period as a result of inflationary pressures and rising energy costs 
impacting the International reporting units' operations. As a result, the Company performed an interim quantitative goodwill 
impairment test.

53 
 
In performing the interim quantitative goodwill impairment test and consistent with prior practice, the Company determined the 
fair value of each of the reporting units using a combination of the income approach and the market approach by assessing each 
of these valuation methodologies based upon availability and relevance of comparable company data and determining the 
appropriate weighting. 
 
Under the income approach, the fair value for each of the reporting units was determined based on the present value of 
estimated future cash flows, discounted at an appropriate risk-adjusted rate. The Company used internal forecasts, updated for 
recent events, to estimate future cash flows estimated using a terminal value calculation, which incorporates historical and 
forecasted trends, including an estimate of long-term future growth rates, based on the Company’s most recent views of the 
long-term outlook for each reporting unit. The internal forecasts include assumptions about future profitability, including the 
expected demand for the Company’s goods and services. Due to the inherent uncertainties involved in making estimates and 
assumptions, actual results may differ from those assumed in the forecasts. The Company derived the discount rates using a 
capital asset pricing model and analyzing published rates for industries relevant to the reporting units to estimate the cost of 
equity financing. The Company used discount rates that are commensurate with the risks and uncertainties inherent in the 
respective businesses and in the internally developed forecasts, updated for recent events. Increased interest rates in the current 
period increased the discount rate associated with the reporting units which contributed to an unfavorable decrease in the 
reporting units value.  
 
The market approach valuation was derived from metrics of publicly traded companies or historically completed transactions of 
comparable businesses. The selection of comparable businesses was based on the markets in which the reporting units operate, 
considering risk profiles, size, geography, and diversity of products and services. 
 
Based upon the results of the interim quantitative goodwill impairment test, the Company recorded an impairment charge of 
$13.8 million within the International reporting units. The impairment was calculated based on the difference between the 
estimated fair value and the carrying value of the reporting units.  Any significant adverse changes in future periods to the 
Company’s internal forecasts or the external market conditions, if any, could reasonably be expected to negatively affect its key 
assumptions and may result in future goodwill impairment charges which could be material. 
 
We elected to perform a quantitative assessment of goodwill on October 1, 2024. Our quantitative assessment considered 
relevant events and circumstances occurring since our interim quantitative goodwill impairment test performed as of September 
30, 2024. Specifically, we considered changes in macroeconomic conditions, industry and market conditions, our internal 
forecasts of future revenue and expenses, our stock price, any significant events affecting the Company and actual changes in 
the carrying values of our net assets. After considering all positive and negative evidence for the assessment as of September 
30, 2024, we concluded that it was not more likely than not that our carrying values exceeded fair values and as such, no 
additional impairment was indicated.  
 
Additionally, as of December 31, 2024, there are no indicators of an impairment. See Note 8-Goodwill of the notes to the 
consolidated financial statements for additional information. 
 
Acquisitions 
 
We allocate the purchase price of acquired businesses to their identifiable tangible assets and liabilities as well as identifiable 
intangible assets, such as customer relationships, technology, non-compete agreements and trade names. Allocations are based 
on estimated fair values of assets and liabilities, which reflects assumptions that would be made by typical market participants 
if they were to buy or sell each asset on an individual asset basis. Certain estimates and judgments are required in the 
application of the fair value techniques, including estimates of the respective acquisitions' future performance and related cash 
flows, selection of a discount rate and economic lives, and use of Level 3 measurements as defined in ASC 820 Fair Value 
Measurements and Disclosure. Deferred taxes are recorded for any differences between the assigned values and tax bases of 
assets and liabilities.  We typically engage third-party valuation experts to assist in determining the fair values for both 
identifiable tangible and intangible assets. The judgments made in determining the estimated fair value assigned to each class of

assets acquired and liabilities assumed, as well as asset lives, could materially impact our results of operations. See Note 7-
Acquisitions to the consolidated financial statements for additional information.

ITEM 7A.                                      QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK 
  
Interest Rate Sensitivity 
  
Our investment portfolio primarily includes cash equivalents for which the market values are not significantly affected by 
changes in interest rates. Our interest rate risk results primarily from our variable rate indebtedness under our credit facility, 
which is influenced by movements in short-term rates. Borrowings under our $190 million revolving credit facility as well as 
our $125 million term loan bear interest at Secured Overnight Financing Rate ("SOFR"), plus a credit spread adjustment and 
applicable SOFR margin, ranging from 1.25% to 2.75%, based upon our Total Consolidated Debt Leverage Ratio. Based on the 
amount of our variable rate debt of $167.2 million at December 31, 2024, an increase in interest rates by one hundred basis 
points from our current rate would increase annual interest expense by approximately $1.9 million. 
  
Foreign Currency Risk 
  
We have foreign currency exposure related to our operations in foreign locations. This foreign currency exposure, particularly 
the Euro, British Pound Sterling, Brazilian Real, Canadian Dollar and the Indian Rupee, arises primarily from the translation of 
our foreign subsidiaries’ financial statements into U.S. Dollars. Gains and losses relating to nonfunctional currency transactions, 
are reported in the Consolidated Statements of Income (Loss). For example, a portion of our annual sales and operating costs 
are denominated in British Pound Sterling and we have exposure related to sales and operating costs increasing or decreasing 
based on changes in currency exchange rates. If the U.S. Dollar increases in value against these foreign currencies, the value in 
U.S. Dollars of the assets and liabilities originally recorded in these foreign currencies will decrease. Conversely, if the U.S. 
Dollar decreases in value against these foreign currencies, the value in U.S. Dollars of the assets and liabilities originally 
recorded in these foreign currencies will increase. Thus, increases and decreases in the value of the U.S. Dollar relative to these 
foreign currencies have a direct impact on the value in U.S. Dollars of our foreign currency denominated assets and liabilities, 
even if the value of these items has not changed in their original currency. Translation adjustments for these movements are 
recorded as a separate component of Accumulated Other Comprehensive Income (Loss) in Stockholder Equity. For the year 
ended December 31, 2024, a 10% movement, favorable or unfavorable, in the average U.S. Dollar exchange rates would cause 
a change in adjusted operating income of approximately $1.5 million. We do not currently enter into forward exchange 
contracts to hedge exposures denominated in foreign currencies. We may consider entering into hedging or forward exchange 
contracts in the future, as sales in international currencies increase due to growth in our International segment. 
  
Fair Value of Financial Instruments 
 
We do not have material exposure to market risk with respect to investments, as our investments consist primarily of highly 
liquid investments purchased with a remaining maturity of three months or less. We do not use derivative financial instruments 
for speculative or trading purposes; however, this does not preclude our adoption of specific hedging strategies in the future.

ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA 
  
Report of Independent Registered Public Accounting Firm 
 
To the Board of Directors and Stockholders of Mistras Group, Inc. 
 
Opinions on the Financial Statements and Internal Control over Financial Reporting 
 
We have audited the accompanying consolidated balance sheets of Mistras Group, Inc. and its subsidiaries (the "Company") as 
of December 31, 2024 and 2023, and the related consolidated statements of income (loss), of comprehensive income (loss), of 
equity and of cash flows for the years then ended, including the related notes (collectively referred to as the "consolidated 
financial statements"). We also have audited the Company's internal control over financial reporting as of December 31, 2024, 
based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring 
Organizations of the Treadway Commission (COSO). 
 
In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial 
position of the Company as of December 31, 2024 and 2023, and the results of its operations and its cash flows for the years 
then ended in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, 
the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2024, 
based on criteria established in Internal Control - Integrated Framework (2013) issued by the COSO. 
 
Basis for Opinions 
 
The Company's management is responsible for these consolidated financial statements, for maintaining effective internal 
control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included 
in Management’s Report on Internal Control Over Financial Reporting appearing under Item 9A. Our responsibility is to 
express opinions on the Company’s consolidated financial statements and on the Company's internal control over financial 
reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight 
Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. 
federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. 
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the 
audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, 
whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material 
respects. 
 
Our audits of the consolidated financial statements 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. 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 audits also included performing such other procedures as we considered necessary in the 
circumstances. We believe that our audits provide a reasonable basis for our opinions. 
 
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 (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and 
dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit 
preparation of financial statements in accordance with 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 

Table of Contents 
56 
company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or 
disposition of the company’s assets that could have a material effect on the financial statements. 
 
Because of 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. 
 
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 (i) relates to accounts or 
disclosures that are material to the consolidated financial statements and (ii) involved our especially challenging, subjective, or 
complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated 
financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate 
opinion on the critical audit matter or on the accounts or disclosures to which it relates. 
 
Revenue Recognition  
 
As described in Note 2 to the consolidated financial statements, the Company derives the majority of its revenue by providing 
services on a time and material basis that are short-term in nature. Revenue is recognized over time as work progresses for the 
Company's service deliverables, which includes providing testing, inspection and mechanical services to customers. Revenue is 
recognized over time, based on time and material incurred to date which best portrays the transfer of control to the customer. 
For the year ended December 31, 2024, the Company’s revenue was $729.6 million, a majority of which relates to revenue 
recognized for providing services on a time and material basis. 
 
The principal consideration for our determination that performing procedures relating to revenue recognition is a critical audit 
matter is a high degree of auditor effort in performing procedures related to the Company's revenue recognition. 
 
Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall 
opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to the 
revenue recognition process, including controls over revenue recognized over time. These procedures also included, among others 
(i) evaluating revenue transactions by testing the issuance and settlement of invoices and credit memos, tracing transactions not 
settled to a detailed listing of accounts receivable, and testing the completeness and accuracy of data provided by management; 
(ii) testing the unbilled revenue accrual at the end of the period, on a test basis, by obtaining the unbilled revenue analysis and 
supporting documentation, such as invoices, purchase orders/contracts, and timesheets; and (iii) confirming, on a sample basis, 
outstanding customer invoice balances as of December 31, 2024 and obtaining and inspecting source documents, including 
invoices, delivery documents, and subsequent cash receipts, where applicable for confirmations not returned.

1. Summary of Significant Accounting Policies and Practices 
  
Description of Business 
  
Mistras Group, Inc., together with its subsidiaries (the "Company"), is a leading “one source” multinational provider of 
integrated technology-enabled asset protection solutions helping to maximize the safety and operational uptime for 
civilization’s most critical industrial and civil assets.  
 
Backed by an innovative, data-driven asset protection portfolio, proprietary technologies and decades-long legacy of industry 
leadership, the Company helps customers with asset-intensive infrastructure in the oil and gas, aerospace and defense, 
industrials, power generation and transmission (including alternative and renewable energy), other process industries and 
infrastructure, research and engineering and other industries towards achieving and maintaining operational excellence. By 
supporting these organizations that help fuel our vehicles and power our society; inspecting components that are trusted for 
commercial, defense, and space craft; building real-time monitoring equipment to enable safe travel across bridges; and helping 
to propel sustainability, the Company helps the world at large. 
 
The Company enhances value for its customers by integrating asset protection throughout supply chains and centralizing 
integrity data through a suite of Industrial Internet of Things ("IoT")-connected digital software and monitoring solutions, 
including OneSuite™, which serves as an ecosystem platform, pulling together all of the Company’s software and data services 
capabilities, for the benefit of its customers. 
 
The Company’s core capabilities also include non-destructive testing (“NDT”) field inspections enhanced by advanced robotics, 
laboratory quality control, laboratory materials services, shop laboratory assurance testing, sensing technologies and NDT 
equipment, asset and mechanical integrity engineering services, and light mechanical maintenance and access services. 
 
The Company has three operating segments.  Our segments are as follows: 
 
• North America This segment provides asset protection solutions predominantly in North America, with the largest 
concentration in the United States, followed by Canada, consisting primarily of NDT, inspection, mechanical and 
engineering services that are used to evaluate the safety, structural integrity and reliability of critical energy, 
industrial and public infrastructure and commercial aerospace components. Software, digital and data services are 
included in this segment. 
  
• International. This segment offers services, products and systems similar to those of the other segments to select 
markets within Europe, the Middle East, Africa, Asia and South America, but not to customers in China and South 
Korea, which are served by the Products and Systems segment. 
  
• Products and Systems. This segment designs, manufactures, sells, installs and services the Company’s asset 
protection products and systems, including equipment and instrumentation, predominantly in the United States. 
 
Recent Developments 
 
The Company provides products and services to countries throughout the Middle East, where lawfully permitted, and in 
accordance with United States regulations. We continue to monitor the on-going conflicts throughout the Middle East. These 
conflicts caused disruptions in the Company's European operations in 2023 with increased costs associated with higher energy 
costs, amongst others. These disruptions have largely subsided in 2024. We may also experience increased costs associated with 
tariffs or trade barriers (including recent U.S. tariffs imposed or threatened to be imposed on China, Canada, Mexico and other 

Table of Contents 
65 
countries and any retaliatory actions taken by such countries). The Company will continue to monitor market conditions and 
respond accordingly. 
 
Principles of Consolidation 
  
The Company follows guidance on the consolidation of variable interest entities ("VIEs") that requires companies to utilize a 
qualitative approach to determine whether it is the primary beneficiary of a VIE. The process for identifying the primary 
beneficiary of a VIE requires consideration of the factors that indicate a party has the power to direct the activities that most 
significantly impact the VIE’s economic performance, including powers granted to the VIE’s program manager, powers contained 
in the VIE governing board and, to a certain extent, a company’s economic interest in the VIE. The Company analyzes its joint 
ventures and classifies them as either: 
• 
a VIE that must be consolidated because the Company is the primary beneficiary, or the joint venture is not a VIE and 
the Company holds the majority voting interest with no significant participative rights available to the other partners; or 
• 
a VIE that does not require consolidation and is treated as an equity method investment because the Company is not the 
primary beneficiary or the joint venture is not a VIE and the Company does not hold the majority voting interest. 
 
As part of the above analysis, if it is determined that the Company has the power to direct the activities that most significantly 
impact the joint venture’s economic performance, the Company considers whether or not it has the obligation to absorb losses or 
rights to receive benefits of the VIE that could potentially be significant to the VIE. 
 
The Company became the primary beneficiary in July 2020 of a VIE in which the Company has a 49% interest in a limited 
partnership, and a 49% stockholder in the corporate general partner of the limited partnership. The Company consolidated the 
financial statements of the VIE with the financial statements of the Company. As of and for the year ended December 31, 2024, 
the VIE had immaterial assets and had approximately $6.0 million of revenue. The Company is the primary sub-contractor of 
the VIE. 
 
The accompanying audited consolidated financial statements include the accounts of Mistras Group, Inc. as well as its wholly-
owned subsidiaries, majority-owned subsidiaries and consolidated VIE. For subsidiaries in which the Company’s ownership 
interest is less than 100%, the non-controlling interests are reported in stockholders’ equity in the accompanying Consolidated 
Balance Sheets. The non-controlling interests in net results, net of tax, is classified separately in the accompanying 
Consolidated Statements of Income (Loss). All significant intercompany accounts and transactions have been eliminated in 
consolidation. The results of operations of companies acquired are included from the date of acquisition. 
 
Reclassifications 
 
Certain amounts in prior periods have been reclassified to conform to the current year presentation. Such reclassifications did 
not have a material effect on the Company's financial condition or results of operations as previously reported. 
 
Use of Estimates 
  
The preparation of financial statements in accordance with U.S. generally accepted accounting principles ("U.S. GAAP") 
requires that the Company make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue and 
expenses and disclosure of contingent assets and liabilities at the date of the financial statements. The Company bases its 
estimates and assumptions on historical experience, known or expected trends and various other assumptions that it believes to 
be reasonable. As future events and their effects cannot be determined with precision, actual results could differ significantly 
from these estimates, which may cause the Company’s future results to be significantly affected. 
  
Cash and Cash Equivalents 
  

Table of Contents 
66 
The Company considers all highly liquid investments purchased with an original maturity of three months or less to be cash 
equivalents. 
  
Accounts Receivable and Allowance for Credit Losses  
 
The Company maintains an allowance for credit losses on its accounts receivable balances, which represents its best estimate of 
current expected credit losses over the contractual life of the accounts receivable. When evaluating the adequacy of its 
allowance for credit losses each reporting period, the Company analyzes accounts receivable balances with similar risk 
characteristics on a collective basis, considering factors such as the aging of receivable balances, payment terms (primarily with 
30 day terms), geographic location, historical loss experience, current information and future expectations (generally considered 
one year which is consistent with expected collectability of the Company's trade receivables).  
 
The Company monitors and considers whether historical loss rates are consistent with expectation of supportable forward-
looking estimates for its trade receivables noting any current or future economic considerations that would require adjusting the 
Company’s historical loss experience. Each reporting period, the Company reassesses whether any accounts receivable no 
longer share similar risk characteristics and should instead be evaluated as part of another pool or on an individual basis. 
Changes to the allowance for credit losses are adjusted through credit loss expense, which is presented within Selling, general 
and administrative expenses in the Consolidated Statements of Income (Loss).  
  
Concentration of Credit Risk 
 
For each of the years ended December 31, 2024 and 2023, no customer represented 10% or more of the Company's revenue.  
 
Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash and cash 
equivalents and accounts receivable. At times, cash deposits may exceed the limits insured by the Federal Deposit Insurance 
Corporation. The Company believes it is not exposed to any significant credit risk or risk of nonperformance of financial 
institutions. 
 
Inventories 
  
Inventories are stated at the lower of cost or net realizable value, as determined by using the first-in, first-out method, or 
market. Work in process and finished goods inventory include material, direct labor, variable costs and overhead. 
  
Purchased and Internal-Use Software 
  
The Company capitalizes certain costs that are incurred to purchase or to create and implement internal-use software, which 
includes software coding, installation and testing. Capitalized costs are amortized on a straight-line basis over three years, the 
estimated useful life of the software. 
  
Property, Plant and Equipment 
  
Property, plant and equipment are recorded at cost. Depreciation of property, plant and equipment is computed utilizing the 
straight-line method over the estimated useful lives of the assets. Amortization of leasehold improvements is computed utilizing 
the straight-line method over the shorter of the remaining lease term or estimated useful life. Repairs and maintenance costs are 
expensed as incurred. 
  
Goodwill 
  
Goodwill represents the excess purchase price of acquired businesses over the fair values attributed to underlying net tangible 
assets and identifiable intangible assets. The Company tests goodwill for impairment at a “reporting unit” level (which for the 
Company is represented by (i) its North America segment, (ii) its Products and Systems segment, (iii) the European component 

Table of Contents 
67 
of its International segment and (iv) the Brazilian component of its International segment). The Company's annual impairment 
test is conducted on the first day of the Company's fourth quarter, which is October 1. Goodwill is also tested for impairment 
whenever an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit 
below its carrying amount.  
 
In testing for goodwill impairment, the Company has the option to first assess qualitative factors to determine whether the 
existence of events or circumstances lead to a determination that it is more likely than not that the fair value of a reporting unit 
is less than its carrying amount. If, after assessing the totality of events and circumstances, the Company concludes that it is not 
more likely than not that the fair value of a reporting unit is less than its carrying amount, then performing a quantitative 
impairment test is not necessary. If the Company concludes otherwise, the Company is required to perform a quantitative 
impairment test. 
 
If the fair value of a reporting unit is less than its carrying value, this is an indicator that the goodwill assigned to that reporting 
unit may be impaired. An impairment will be recorded in the amount that the fair value is less than the carrying value. The 
Company considers the income and market approaches to estimate the fair value of its reporting units, which requires 
significant judgment and assumptions related to revenue growth rates, gross margins, EBIT margins, and market multiples.  
 
See Note 8-Goodwill for additional information related to the Company's goodwill impairment test during 2024.   
 
Impairment of Long-lived Assets 
  
The Company reviews the recoverability of its long-lived assets (or asset groups) whenever events or changes in circumstances 
indicate that the carrying amount of the long-lived asset (group) might not be recoverable. The assessment for potential 
impairment is based primarily on the Company’s ability to recover the carrying value of its long-lived assets from expected 
future undiscounted cash flows. If the total expected future undiscounted cash flows are less than the carrying amount of the 
assets, a loss is recognized for the difference between fair value (computed based upon the expected future discounted cash 
flows) and the carrying value of the assets. 
  
Acquisitions 
 
The Company allocates the purchase price of acquired businesses to their identifiable tangible assets and liabilities as well as 
identifiable intangible assets, such as customer relationships, technology, non-compete agreements and trade names. Certain 
estimates and judgments are required in the application of the fair value techniques, including estimates of the respective 
acquisition's future performance and related cash flows, selection of a discount rate and economic lives, and use of Level 3 
measurements as defined in ASC No. 820, Fair Value Measurements and Disclosure. Deferred taxes are recorded for any 
differences between the assigned values and tax bases of assets and liabilities.  
 
Research and Engineering 
 
Research and product development costs are expensed as incurred. 
 
Advertising, Promotions and Marketing 
  
The costs for advertising, promotion and marketing programs are expensed as incurred and are included in selling, general and 
administrative expenses. Advertising expense was approximately $1.0 million, $1.4 million and $2.0 million for the years ended 
December 31, 2024, 2023 and 2022, respectively. 
  
Fair Value of Financial Instruments 
  
The carrying amounts of cash and cash equivalents, accounts receivable, accounts payable and other financial current assets and 
liabilities approximate fair value based on the short-term nature of the items.

Foreign Currency Translation 
  
The financial position and results of operations of the Company’s foreign subsidiaries are measured using their functional 
currencies, which are their local currencies. Assets and liabilities of foreign subsidiaries are translated into the U.S. Dollar at the 
exchange rates in effect at the balance sheet date. Income and expenses are translated at the average exchange rate during the 
period. Translation gains and losses are reported as a component of other comprehensive income (loss) for the period and 
included in accumulated other comprehensive income (loss) within stockholders’ equity. 
  
Foreign currency (gains) losses arising from transactions denominated in currencies other than the functional currency are 
included in net income, reported in selling, general and administrative expenses, and were approximately $(1.8) million, $1.3 
million, and $(0.2) million for the years ended December 31, 2024, 2023 and 2022, respectively. 
  
Self-Insurance 
  
The Company is self-insured for certain losses relating to workers’ compensation and health benefit claims. The Company 
maintains third-party excess insurance coverage for all workers' compensation and health benefit claims in excess of 
approximately $0.3 million per occurrence to reduce its exposure from such claims. Self-insured losses are accrued when it is 
probable that an uninsured claim has been incurred but not reported and the amount of the loss can be reasonably estimated at 
the balance sheet date. 
  
Share-based Compensation 
  
The value of services received from employees and directors in exchange for an award of an equity instrument is measured 
based on the grant-date fair value of the award. Such value is recognized as a non-cash expense on a straight-line basis over the 
minimum period the individual provides services, which is typically the vesting period of the award with the exception of 
awards with graded vesting that contain an internal performance measure where each tranche is recognized on a straight-line 
basis over its vesting period subject to the probability of meeting the performance requirements and adjusted for the number of 
shares expected to be earned. Awards to certain employees eligible for retirement prior to the award becoming fully vested are 
amortized to expense over the period through the date that the employee first becomes eligible to retire and is no longer 
required to provide service to earn the award. As share-based compensation expense is based on awards ultimately expected to 
vest, the amount of expense is reduced for estimated forfeitures. The cost of these awards is recorded in selling, general and 
administrative expenses in the Company’s Consolidated Statements of Income (Loss). 
  
Income Taxes 
  
Income taxes are accounted for under the asset and liability method. We recognize deferred tax assets and liabilities at enacted 
income tax rates for the temporary differences between the financial reporting bases and the tax bases of our assets and 
liabilities. Any effects of changes in income tax rates or tax laws are included in the provision for income taxes in the period of 
enactment. Our net deferred tax assets primarily consist of net operating loss carry forwards, or NOLs. A valuation allowance is 
provided if it is more likely than not that some or all of a deferred income tax asset will not be realized. A current tax liability or 
asset is recognized for the estimated taxes payable or refundable on tax returns for the current and prior years. 
 
We recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be 
sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in 
the financial statements from such a position are measured based on the largest benefit that has a greater than 50% likelihood of 
being realized upon ultimate resolution. 
 
Recent Accounting Pronouncements 
 

Table of Contents 
69 
In November 2023, the Financial Accounting Standards Board ("FASB") issued ASU 2023-07, Segment Reporting (Topic 280) 
to expand the disclosures about a public entity's reportable segments and address requests from investors for additional, more 
detailed information about a reportable segment's expenses. The new standard is effective for fiscal years beginning after 
December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. We adopted the provisions of 
this ASU in the fourth quarter of 2024 and applied the provisions retrospectively to each period presented in the consolidated 
financial statements. Adoption of the new standard did not have a material impact on our consolidated financial statements. 
 
In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740) to enhance the transparency and decision 
usefulness of income tax disclosures, primarily related to the rate reconciliation and income taxes paid disclosures. The new 
standard is effective for fiscal years beginning after December 15, 2024. We do not expect the impact of ASU 2023-09 to be 
material on our financial statements. 
 
2. Revenue 
  
The Company derives the majority of its revenue by providing services on a time and material basis that are short-term in 
nature. The Company accounts for revenue in accordance with ASC Topic 606, Revenue from Contracts with Customers. 
 
Performance Obligations 
 
The Company provides highly integrated and bundled inspection services to its customers. The majority of the Company's 
contracts have a single performance obligation as the promise to transfer the individual goods or services is not separately 
identifiable from other promises in the contracts and is, therefore, not distinct. For contracts with multiple performance 
obligations, the Company allocates the contract’s transaction price to each performance obligation using the Company's best 
estimate of the standalone selling price of each distinct good or service in the contract. The primary method used to estimate 
standalone selling price is a relative selling price based on price lists. 
 
Contract modifications are not routine in the performance of the Company's contracts. Generally, when contracts are modified, 
the modification is to account for changes in scope to the goods and services that are provided. In most instances, contract 
modifications are for goods or services that are distinct, and, therefore, are accounted for as a separate contract. 
 
The Company's performance obligations are satisfied over time as work progresses or at a point in time. The majority of the 
Company's revenue is recognized over time as work progresses for the Company's service deliverables, which includes 
providing testing, inspection and mechanical services to our customers. Revenue is recognized over time, based on time and 
material incurred to date which best portrays the transfer of control to the customer. The Company also utilizes an available 
practical expedient that provides for revenue to be recognized in an amount that corresponds directly with the value to the 
customer of the entity’s performance completed to date. Fixed fee arrangements are determined based on expected labor, 
material, and overhead to be consumed on fulfillment of such services. For these arrangements, revenue is recognized on a cost-
to-cost method tracked on an input basis.  
 
The majority of our revenue recognized at a point in time is related to product sales when the customer obtains control of the 
asset, which is generally upon shipment to the customer. Contract costs include labor, material and overhead. 
 
The Company expects any significant remaining performance obligations to be satisfied within one year. 
 
Contract Estimates 
 

Table of Contents 
70 
The majority of the Company's revenues are short-term in nature. The Company enters into master service agreements 
("MSAs") with customers that specify an overall framework and contract terms. The actual contracting to provide services or 
furnish products are triggered by a work order, purchase order, or some similar document issued pursuant to an MSA which sets 
forth the scope of services and/or identifies the products to be provided. From time-to-time, the Company may enter into 
longer-term contracts, which can range from several months to several years. Revenue on certain contracts is recognized as 
work is performed based on total costs incurred to date in relation to the total estimated costs for the performance of the 
contract at completion. This includes contract estimates of costs to be incurred for the performance of the contract. Cost 
estimation is based upon the professional knowledge and experience of the Company's project managers, engineers and 
financial professionals. Factors that are considered in estimating the work to be completed include the availability of materials, 
the effect of any delays in the Company's project performance and the recoverability of any claims. Whenever revisions of 
estimates, contract costs and/or contract values indicate that the contract costs will exceed estimated revenues, thus creating a 
loss, a provision for the total estimated loss is recorded in that period.

Contract Balances 
 
The timing of revenue recognition, billings and cash collections results in billed accounts receivable, unbilled receivables 
(contract assets), and customer advances and deposits (contract liabilities) on the Consolidated Balance Sheets. Amounts are 
generally billed as work progresses in accordance with agreed-upon contractual terms, generally at periodic intervals (e.g., 
weekly, bi-weekly or monthly). Generally, billing occurs subsequent to revenue recognition, resulting in contract assets. 
However, the Company sometimes receives advances or deposits from its customers before revenue is recognized, resulting in 
contract liabilities. These assets and liabilities are aggregated on an individual contract basis and reported on the Consolidated 
Balance Sheets at the end of each reporting period within accounts receivable, net or accrued expenses and other current 
liabilities. 
 

Table of Contents 
72 
Revenue recognized for 2024 and 2023, that was included in the contract liability balance at the beginning of the year was $6.7 
million and $6.3 million, respectively. Changes in the contract asset and liability balances during the years ended December 31, 
2024 and 2023, were not impacted by any other factors. The Company applies the practical expedient to expense incremental 
costs incurred related to obtaining a contract when the amortization period of the asset that the Company otherwise would have 
recognized is one year or less.  
   
3. Earnings per Share 
  
Basic earnings (loss) per share is computed by dividing net income (loss) by the weighted-average number of shares 
outstanding during the period. Diluted earnings per share is computed by dividing net income (loss) by the sum of (1) the 
weighted-average number of shares of common stock outstanding during the period, and (2) the dilutive effect of assumed 
conversion of equity awards using the treasury stock method. With respect to the number of weighted-average shares 
outstanding (denominator), diluted shares reflects: (i) the exercise of options to acquire common stock to the extent that the 
options’ exercise prices are less than the average market price of shares of common stock during the period and (ii) the pro 
forma vesting of restricted stock units. 
  
The following table sets forth the computations of basic and diluted earnings (loss) per share (in thousands except share data):

The Company had $21.3 million and $18.5 million of unbilled revenues accrued as of December 31, 2024 and December 31, 
2023, respectively, which is included within the trade accounts receivable balance above. Unbilled revenue is generally billed in 
the subsequent quarter to their revenue recognition. The Company considers unbilled receivables as short-term in nature as they 
are normally converted to trade receivables within 90 days, thus future changes in economic conditions will not have a

The Company reviews goodwill for impairment on a reporting unit basis on October 1 of each year and whenever events or 
changes in circumstances indicate the carrying value of goodwill may not be recoverable. 
 
During the third quarter of 2023, a triggering event was identified within the Company's reporting units within the International 
segment due to decreased gross margin in the current period as a result of inflationary pressures and rising energy costs 
impacting the International reporting units' operations. As a result, the Company performed an interim quantitative goodwill 
impairment test. 
 
In performing the interim quantitative goodwill impairment test and consistent with prior practice, the Company determined the 
fair value of each of the reporting units using a combination of the income approach and the market approach by assessing each 
of these valuation methodologies based upon availability and relevance of comparable Company data and determining the 
appropriate weighting. 
 
Under the income approach, the fair value for each of the reporting units was determined based on the present value of 
estimated future cash flows, discounted at an appropriate risk-adjusted rate. The Company used internal forecasts, updated for 
recent events, to estimate future cash flows using a terminal value calculation, which incorporates historical and forecasted 
trends, including an estimate of long-term future growth rates, based on the Company’s most recent views of the long-term 
outlook for each reporting unit. The Company's internal forecasts include assumptions about future profitability, including the 
expected demand for the Company’s goods and services. Due to the inherent uncertainties involved in making estimates and 
assumptions, actual results may differ from those assumed in the forecasts. The Company derived the discount rates using a 
capital asset pricing model and analyzing published rates for industries relevant to the reporting units to estimate the cost of 
equity financing. The Company used discount rates that are commensurate with the risks and uncertainties inherent in the 
respective businesses and in the Company's internally developed forecasts and which are updated for recent events. Increased 

Table of Contents 
75 
interest rates in the current period increased the discount rate associated with the reporting units which contributed to an 
unfavorable decrease in the reporting units value.  
 
The market approach valuation was derived from metrics of publicly traded companies or historically completed transactions of 
comparable businesses. The selection of comparable businesses was based on the markets in which the reporting units operate, 
considering risk profiles, size, geography, and diversity of products and services. 
 
Based upon the results of the interim quantitative goodwill impairment test, the Company recorded an impairment charge of 
$13.8 million within the International reporting units. The impairment was calculated based on the difference between the 
estimated fair value and the carrying value of the reporting units and is included in Goodwill impairment charges on the 
condensed consolidated statements of income (loss) for the year ended December 31, 2023. Any significant adverse changes in 
future periods to the Company’s internal forecasts or the external market conditions, if any, could reasonably be expected to 
negatively affect its key assumptions and may result in future goodwill impairment charges which could be material. 
 
The Company's cumulative goodwill impairment as of December 31, 2024 was $114.0 million, of which $57.2 million related 
to the North America segment, $43.6 million related to the International segment and $13.2 million related to the Products and 
Systems segment.

Senior Credit Facility 
  
On August 1, 2022, the Company entered into a credit agreement (the “Credit Agreement”) which provides the Company with a 
$190 million, 5-year committed revolving credit facility and a $125 million term loan with a balance of $107.5 million as of 
December 31, 2024. The Credit Agreement permits the Company to borrow up to $100 million in non-US dollar currencies and 
to use up to $20 million of the credit limit for the issuance of letters of credit. Both the revolving line of credit and the term loan 
under the Credit Agreement have a maturity date of July 30, 2027. 
 
The Credit Agreement has the following key terms, conditions and financial covenants: 
 
• 
Borrowings bear interest at Secured Overnight Financing Rate ("SOFR") plus a credit spread adjustment and 
applicable SOFR margin ranging from 1.25% to 2.75%, based upon our Total Consolidated Debt Leverage Ratio 
(defined below); under the Credit Agreement, the margin was based upon the LIBOR margin. 

Table of Contents 
77 
◦ 
Total Consolidated Debt Leverage Ratio means the ratio of (a) Total Consolidated Debt to (b) EBITDA (as 
defined in the Credit Agreement) for the trailing four consecutive fiscal quarters. 
◦ 
Total Consolidated Debt means all indebtedness (including subordinated debt) of the Company on a 
consolidated basis. 
 
• 
The Company has the benefit of the lowest SOFR margin if its Total Consolidated Debt Leverage Ratio is equal to or 
less than 1.25 to 1.0, and the margin increases as the ratio increases, to the maximum margin if the ratio is greater than 
3.75 to 1.0. The Credit Agreement is secured by liens on substantially all of the assets of the Company and certain of 
its U.S subsidiaries and is guaranteed by those U.S subsidiaries. 
 
• 
The Company is required to maintain a Total Consolidated Debt Leverage Ratio of no more than 4.0 to 1.0 at the end 
of each quarter through June 30, 2023 and stepping down to a maximum permitted ratio of no more than 3.75 to 1.0 
for the remainder of the term.  
 
• 
The Company is required to maintain a Fixed Charge Coverage Ratio of 1.25 to 1.0 for the duration of the Credit 
Agreement, as defined in the Credit Agreement.  
 
• 
The Credit Agreement limits the Company’s ability to, among other things, create liens, make investments, incur more 
indebtedness, merge or consolidate, make dispositions of property, pay dividends, make distributions to stockholders 
or repurchase our stock, enter into a new line of business, enter into transactions with affiliates and enter into 
burdensome agreements. 
 
• 
The Credit Agreement does not limit the Company’s ability to acquire other businesses or companies except that the 
acquired business or company must be in the Company's line of business, the Company must be in compliance with 
the financial covenants on a pro forma basis after taking into account the acquisition, and the Company must provide 
written notice at least five business days prior to the date of an acquisition of $10 million or more. 
 
• 
Quarterly payments on the term loan of $1.56 million through June 30, 2024, then increasing to $2.34 million through 
June 30, 2025, and to $3.12 million for each quarterly payment thereafter through maturity. 
  
As of December 31, 2024, the Company had borrowings of $167.2 million and a total of $3.1 million of letters of credit 
outstanding under the Credit Agreement. The Company has capitalized costs associated with debt modifications of $0.8 million 
as of December 31, 2024, which is included in Other assets on the Consolidated Balance Sheet and will be amortized into 
interest expense over the remaining term of the Credit Agreement through July 30, 2027. 
 
As of December 31, 2024, the Company was in compliance with the terms of the Credit Agreement. The Company 
continuously monitors compliance with the covenants contained in the Credit Agreement. The Company believes that it is 
probable that the Company will be able to comply with the financial covenants in the Credit Agreement and that sufficient 
credit remains available under the Credit Agreement to meet the Company's liquidity needs. However, such matters cannot be 
predicted with certainty. 
 
Other Debt 
  
The Company's other debt includes bank financing provided at the local subsidiary level used to support working capital 
requirements and fund capital expenditures. At December 31, 2024, there was an aggregate of approximately $2.5 million 
outstanding, payable at various times through 2030. Monthly payments range from $1 thousand to $15 thousand, and interest 
rates range from 0.4% to 3.5%.

12.  Fair Value Measurements 
  
The Company performs fair value measurements in accordance with the guidance provided by ASC 820, Fair Value 
Measurements and Disclosures. ASC 820 defines fair value as the price that would be received to sell an asset or paid to 
transfer a liability in an orderly transaction between market participants at the measurement date. It also establishes a three-
level hierarchy that prioritizes the inputs used to measure fair value. The three levels of the hierarchy are defined as follows: 
  
Level 1 — Inputs are unadjusted quoted prices in active markets for identical assets or liabilities that the Company has 
the ability to access at the measurement date. 
  
Level 2 — Observable inputs other than quoted prices included in Level 1, including quoted prices for similar assets or 
liabilities in active markets, quoted prices for identical assets or liabilities in inactive markets, inputs other than quoted prices 
that are observable for the asset or liability and inputs derived principally from or corroborated by observable market data. 
 
Level 3 — Unobservable inputs reflecting the Company’s own assumptions about inputs that market participants 
would use in pricing the asset or liability based on the best information available. 
  
Financial instruments measured at fair value on a recurring basis 
 
The fair value of contingent consideration liabilities was estimated using a discounted cash flow technique with significant 
inputs that are not observable in the market and thus represents a Level 3 fair value measurement as defined in ASC 820. The 
significant inputs in the Level 3 measurement not supported by market activity include the probability assessments of expected 
future cash flows related to the acquisitions, appropriately discounted considering the uncertainties associated with the 
obligation, and as calculated in accordance with the terms of the applicable acquisition agreements.

approximates their carrying amounts based on anticipated interest rates which management believes would currently be 
available to the Company for similar issuances of debt. 
 
13. Share-Based Compensation 
  
The Company grants share-based incentive awards to its eligible employees and non-employee directors under its 2016 Long-
Term Incentive Plan (the "2016 Plan"). Awards granted under the 2016 Plan may be in the form of stock options, restricted 
stock units and other forms of share-based incentives, including performance-based restricted stock units, stock appreciation 
rights and deferred stock rights. At the annual shareholders meeting on May 14, 2024, the Company’s shareholders approved an 
amendment to the 2016 Plan, including an increase to the total number of shares that may be issued under the 2016 Plan by 
1.3 million, for a total of 6.2 million shares that are authorized for issuance under the 2016 Plan, of which approximately 
1,850,000 shares were available for future grants as of as of December 31, 2024.  
 
Stock Options 
  
On October 11, 2023, Mr. Stamatakis was granted an award of stock options to purchase 250,000 shares of common stock of 
the Company, with an exercise price of $5.36, the closing price of the Company's common stock as quoted on the New York 
Stock Exchange on the grant date (the "Options"). The Options were granted as an inducement for Mr. Stamatakis to accept the 
position of Interim President and CEO of the Company and were therefore granted outside the 2016 Plan, as permitted by the 
rules of the NYSE. The Options can be exercised any time after the grant date until its expiration date, which is the earlier of 10 
years from the grant date or one year following the date Mr. Stamatakis is no longer serving as an officer, director or in any 
other capacity of the Company. The Company recognized all share-based compensation expense related to the stock options 
granted in the fourth quarter of 2023 when they were granted, and no further unrecognized share-based compensation expense 
remains as of the end of the current period. 
 
For the year ended 2022, the Company did not recognize any share-based compensation expense related to stock option awards, 
as the one outstanding stock option award was already fully vested and expired during the year ended 2022. No unrecognized 
compensation costs remained related to the stock option awards. In addition, there were no stock options exercised during the 
years ended December 31, 2024, 2023 and 2022. 
   
The following table sets forth a summary of the stock option activity, weighted-average exercise prices and options outstanding 
as of December 31, 2024, 2023 and 2022 as follows (in thousands, except per share amounts and years):

Restricted Stock Unit Awards 
  
Restricted Stock Units generally vest ratably on each of the first four anniversary dates of issuance. The Company recognized 
approximately $4.1 million, $4.9 million and $3.7 million of share-based compensation for the years ended December 31, 2024, 
2023 and 2022, respectively, related to restricted stock unit awards. As of December 31, 2024, there was approximately $7.5 
million of unrecognized compensation costs, net of estimated forfeitures, related to restricted stock unit awards, which are 
expected to be recognized over a remaining weighted average period of 2.2 years. Upon vesting, restricted stock units are 
generally net share-settled to cover the required minimum withholding tax and the remaining amount is converted into an 
equivalent number of shares of common stock.

Performance Restricted Stock Units 
 
The Company maintains Performance Restricted Stock Units ("PRSUs") that have been granted to select executives and senior 
officers whose ultimate payouts may vary between zero and 200% of the target award, based on the Company’s performance 
over a one-year period based on specific metrics approved by the Compensation Committee of the Board of Directors of the 
Company (the "Compensation Committee"). 
 
For 2022, the Compensation Committee utilized the following three performance metrics for PRSUs approved in that year. The 
three metrics were: 
1. Free Cash Flow defined as net cash provided by operating activities less purchases of property, plant, equipment and 
intangible assets and is subject to adjustments approved by the Compensation Committee. 

Table of Contents 
81 
2. Adjusted EBITDA defined as net income attributable to the Company plus: interest expense, provision for income taxes, 
depreciation and amortization, share-based compensation expense and certain acquisition related costs (including 
transaction due diligence costs and adjustments to the fair value of contingent consideration), foreign exchange (gain) 
loss and, if applicable, certain special items which are noted. 
3. Total Shareholder Return ("TSR") measures the total return to shareholders of the Company during the 1-year 
performance period versus the total return to the shareholders of a predefined peer group of companies that provide 
inspection, testing, certification or similar industrial services. The return will be measured by the year over year percent 
change in share price. The share prices used to calculate the return are the average share price during the 20-trading day 
period ending on the initial measurement date (the last 20 trading days preceding the performance period), compared to 
the average share price during the 20-trading day period ending on the final measurement date (the last 20 trading days 
of the performance period). Any cash dividends or distributions paid in 2022 were added to calculate the return to 
shareholders during the year. TSR is considered a market condition for which the fair value of PRSUs with this condition 
is determined using a Monte Carlo valuation model. Key assumptions in the Monte Carlo valuation model included:  
a. 
Expected Volatility. Expected volatility of the Company’s common stock at the date of grant was estimated 
based on a historical average volatility rate for the approximate 1-year performance period.  
b. Dividend Yield. The dividend yield assumption was based on historical and anticipated dividend payouts 
(assumed at zero).  
c. 
Risk-Free Interest Rate. The risk-free interest rate assumption was based on observed interest rates consistent 
with the approximate 1-year performance measurement period. 
 
For 2023, the Compensation Committee used the following three performance metrics for PRSUs approved in that year. 
 
1. Free Cash Flow defined as net cash provided by operating activities less purchases of property, plant, equipment and 
intangible assets and is subject to adjustments approved by the Compensation Committee. 
2. Adjusted EBITDA defined as net income attributable to the Company plus: interest expense, provision for income taxes, 
depreciation and amortization, share-based compensation expense and certain acquisition related costs (including 
transaction due diligence costs and adjustments to the fair value of contingent consideration), foreign exchange (gain) 
loss and, if applicable, certain special items which are noted. 
3. Revenue  
 
For PRSUs awarded in 2024, the Compensation Committee utilized the same metrics as 2023 PRSUs, but with revised 
performance goals.  
 
PRSUs are equity-classified and compensation costs related to PRSUs with performance conditions are initially measured using 
the fair value of the underlying stock at the date of grant. Compensation costs related to the PRSUs with performance conditions 
are subsequently adjusted for changes in the expected outcomes of the performance conditions. Compensation cost related to the 
PRSUs with a market condition is not reversed if the market condition is not achieved, provided the employee requisite service 
has been rendered. Earned PRSUs generally vest ratably in four equal annual installments over the four years following 
completion of the performance period, for a total requisite service period of up to five years, and have no dividend equivalent 
rights.

For the year ended December 31, 2024, 295,000 PRSUs were granted. There was a 201,000 net unit reduction to these awards, 
which represents the Company's achievement of the threshold level of the Adjusted EBITDA target and not achieving the 
revenue or FCF performance goals, during the year ended December 31, 2024.  
 
For the year ended December 31, 2023, 282,000 PRSUs were granted. There was a 305,000 net unit reduction to these awards, 
which reflects the Company's performance against specified goals, during the year ended December 31, 2023.  
 
For the year ended December 31, 2022, 341,000 PRSUs were granted. There was a 285,000 unit reduction to these awards, 
which reflects the Company's performance against specified goals, during the year ended December 31, 2022. 
 
Compensation expense related to all PRSUs described above was $0.4 million, $0.7 million, and $1.2 million for the years 
ended December 31, 2024, 2023 and 2022, respectively. At December 31, 2024, there was $0.6 million of total unrecognized 
compensation costs related to approximately 125,000 unvested performance restricted stock units. These costs are expected to 
be recognized over a weighted-average period of approximately 2.3 years. 
 
For the years ended December 31, 2024, 2023 and 2022, the income tax benefit recognized on all share based compensation 
arrangements referenced above was approximately $1.6 million, $0.8 million, and $1.6 million, respectively.

On June 28, 2019, the Canadian province of Alberta enacted the Job Creation Tax Cut which reduced the Alberta corporate 
income tax rate from 12% to 11% starting in 2019 with further annual reductions to 10% in 2020, 9% in 2021, and 8% in 2022.  
 
On March 27, 2020, the United States enacted the Coronavirus Aid, Relief, and Economic Security Act (CARES Act). The 
CARES Act is an approximately $2 trillion emergency economic stimulus package in response to the Coronavirus outbreak, 
which among other things contains numerous income tax provisions.  Some of these tax provisions are effective retroactively 
for years ending before the date of enactment. The CARES Act provides a five-year carryback of net operating losses generated 
in years 2018 through 2020. As the statutory federal income tax rate applicable to certain years within the carryback period is 

Table of Contents 
84 
35%, carryback to those years of our estimated 2020 annual federal tax loss provides a tax benefit in excess of the current 
federal statutory rate of 21%, resulting in an increased income tax benefit of $1.9 million. The income tax effects of the CARES 
Act resulted in a cash refund of approximately $4.9 million in 2021 of taxes paid in prior years.  
 
On December 27, 2020, the United States enacted the Consolidated Appropriations Act, 2021, (the "Appropriations Act") an 
additional stimulus package providing financial relief for individuals and small business. The Appropriations Act contains a 
variety of tax provisions, including full expensing of business meals in 2021 and 2022, and expansion of the employee retention 
tax credit. The Appropriations Act did not have a material impact on our consolidated financial position, results of operations, 
and cash flows.           
 
In response to the COVID-19 pandemic, the American Rescue Plan Act was signed into law on March 11, 2021.  This act, 
among other things, provides economic relief provisions to individuals and funding to certain businesses and programs. This 
guidance did not have a material impact on our consolidated financial position, results of operations, and cash flows.     
 
In August 2022 the United States enacted the Inflation Reduction Act (“IRA”) of 2022 (Public Law No. 117-169), which 
includes a 15% book minimum tax on corporations with financial accounting profits over 1 billion US dollars (USD) and a 1% 
excise tax on certain stock buybacks. The IRA also contains numerous clean energy tax incentives related to electricity 
production, carbon sequestration, alternative vehicles and fuels, and residential and commercial energy efficiency. The 
Company does not expect this act to have a material impact.

As of December 31, 2024, the Company had no federal net operating loss carry forwards (NOLs). In addition, as of December 
31, 2024, the Company had state and foreign NOLs of $23.8 million and $12.2 million, respectively. Approximately 
$11.8 million of state NOLs expire at various times from 2023 to 2042, while the remainder of the Company's state NOLs do 
not expire. Approximately $1.9 million of the foreign NOLs expire at various times from 2023 to 2041, while the remainder of 
the Company's foreign NOLs do not expire.  
 
In assessing the ability to realize deferred tax assets, management considers whether it is more likely than not that some portion 
or all of the deferred tax assets will be realized.  Valuation allowances are provided when management believes the Company's 
deferred tax assets are not recoverable based on future reversals of existing taxable temporary differences, taxable income in 
prior carryback year(s) if carryback is permitted under the tax law, and an assessment of estimated future taxable income, 
exclusive of reversing temporary differences and carryforwards, that incorporates on going, prudent and feasible tax planning 
strategies.  At December 31, 2024 and December 31, 2023, the Company had a valuation allowance of approximately 
$4.0 million and $6.0 million, respectively, primarily against certain state and foreign NOLs and other specific deferred tax 
assets. The net decrease in the valuation allowance of approximately $2.0 million is primarily attributable to state and foreign 
net operating losses and changes in foreign exchange rates, offset by a reduction of expiring losses. Except for those deferred 
tax assets subject to the valuation allowance, management believes that it will realize all deferred tax assets as a result of 
sufficient future taxable income in each tax jurisdiction in which the Company has deferred tax assets.     .

The Company has recorded the unrecognized tax benefits in other long-term liabilities in the consolidated balance sheets. As of 
December 31, 2024 and December 31, 2023, there were approximately $0.3 million and $0.3 million of unrecognized tax 
benefits, respectively, including penalties and interest. If the Company recognized these unrecognized tax benefits, 
approximately $0.3 million and $0.3 million would favorably affect the effective tax rate for both December 31, 2024 and 
December 31, 2023, respectively. Interest and penalties related to unrecognized tax benefits are recorded in income tax expense 
and are not significant for the years ended December 31, 2024, 2023 and 2022. The Company anticipates a decrease to its 
unrecognized tax benefits of $0.1 million excluding interest and penalties within the next 12 months. 
  
The Company is subject to taxation in the United States and various states and foreign jurisdictions. The Company is no longer 
subject to U.S. federal income tax examinations for years ending before December 31, 2017 and generally is no longer subject 
to state, local or foreign income tax examinations by tax authorities for years ending before December 31, 2019. Currently the 
Company is undergoing a federal tax audit for years ending December 31, 2018 through December 31, 2020. 
  
As previously noted, the Tax Act made significant changes to the taxation of undistributed earnings, requiring that all 
previously untaxed earnings and profits of the Company's controlled foreign operations be subjected to the transition tax. Since 
these earnings have now been subjected to U.S. federal tax, they would only be potentially subject to limited other taxes, 
including foreign withholding and certain state taxes. As of December 31, 2024, the Company has not recognized a deferred tax 
liability for foreign withholdings and state taxes on its undistributed international earnings or losses of its foreign subsidiaries 
since it intends to indefinitely reinvest the earnings outside the United States. The Company has estimated $74.4 million of 
unremitted international earnings which provides an unrecorded deferred tax liability related to undistributed international 
earnings of approximately $1.2 million.

15. Employee Benefit Plans 
  
The Company provides a 401(k) savings plan for eligible U.S. based employees. Employee contributions are discretionary up to 
the IRS limits each year and catch up contributions are allowed for employees 50 years of age or older. Under the 401(k) plan, 
employees become eligible to participate on the first day of the month after three months of continuous service. Under this plan, 
the Company matches 50% of the employee’s contributions up to 6% of the employee’s annual compensation, as defined by the 
plan. There is a five-year vesting schedule for the Company match.  
 
The Company’s contribution to the plan was $4.1 million, $3.9 million, and $3.0 million for the years ended December 31, 
2024, 2023 and 2022, respectively. 
 
The Company's subsidiary participated with other employers in contributing to the Boilermaker-Blacksmith National Pension 
Trust (EIN 48-6168020) (“Boilermakers”) and Plumbers and Pipefitters National Pension Fund (EIN 52-6152779) 
(“Pipefitters”), multi-employer defined benefit pension plans, which cover certain U.S. based union employees. The plans 
provide pension benefits with contribution rates that are collectively bargained between participating employers and their 
affiliated Boilermakers and Pipefitters local unions. Both the Boilermakers and Pipefitters plans are approximately 80 percent 
funded as of the latest Form 5500 filed, respectively. The Company did not make any contributions to the Boilermakers plan 
during the years ended December 31, 2024 and 2023 while making de minimis contributions to the Pipefitters plan during the 
same periods. See Note 18-Commitments and Contingencies, Pension Related Contingencies, for additional detail. 
 
The Company has other benefit plans covering certain employees throughout the Company.  Amounts charged to expense under 
these plans were not significant in any year. 
  
16. Related Party Transactions 
  
The Company leases its headquarters under an operating lease from a stockholder and director of the Company. On August 1, 
2014, the Company extended its lease at its headquarters requiring monthly payments through October 2024. Total rent 
payments made during the year ended December 31, 2024 were approximately $1.0 million. See Note 17-Leases for further 
detail.  
  
The Company receives benefits consulting services from Capital Management Enterprise (“CME”). Manuel N. Stamatakis,  
Executive Chairman of our Board of Directors, is the Chief Executive Officer of CME. The Company does not pay any fees to 
CME and any compensation CME receives related to work for the Company is received by commissions paid by the third-party 
benefit providers.  
  
17. Leases 
  
The Company leases certain office and operating facilities, machinery, equipment, and vehicles. Concurrent with the adoption 
of ASC 842, the Company recognized a right-of-use (ROU) asset and lease liability based on the present value of the future 
lease payments over the lease term for each lease agreement. The Company elected not to recognize a ROU asset and lease 
liability for leases with terms of 12 months or less and will continue to recognize lease expense for these leases on a straight-
line basis over the lease term. The Company has leases with both lease components and non-lease components, such as 
common area maintenance, utilities, or other repairs and maintenance.  For all asset classes, the Company decided to utilize the 
practical expedient to include both fixed lease components and fixed non-lease components in calculating the ROU asset and 
lease liability. The Company identified variable lease payments, such as maintenance payments based on actual activities 
performed or costs incurred, at lease commencement by assessing the nature of the payment provisions, including whether the 
payments are subject to a minimum charge. Many of the Company's leases include one or more options to renew. When it is 
reasonably certain that the Company will exercise the option, the Company will include the impact of the option in the lease 
term for purposes of determining future lease payments. As the Company is unable to determine the discount rate implicit in its 

Table of Contents 
87 
lease agreements, the Company uses its incremental borrowing rate on the commencement date to calculate the present value of 
future payments.

Included within the balance of operating leases is a lease for the Company’s headquarters which is with a related party. The 
ROU liability for this facility is approximately $1.8 million as of December 31, 2024 and $0.8 million as of December 31, 
2023. Total rent payments for this facility were approximately $1.0 million and $1.0 million during the years ended 
December 31, 2024 and 2023. An agreement was reached with the related party to reduce rental payments by 12.5% for the 
lease of the Company’s headquarters, effective February 2022 as part of a voluntary reduction. 
 
As of December 31, 2024 and 2023, the total ROU assets attributable to finance leases are approximately $17.9 million and 
$14.5 million, respectively, which is included in Property, plant, and equipment, net on the Consolidated Balance Sheets.

Legal Proceedings and Government Investigations 
  
The Company is periodically involved in lawsuits, investigations and claims. While uncertainties exist with respect to the 
ultimate resolution of lawsuits, investigations and claims asserted against it, the Company, based on currently available 
information, does not believe that any currently pending or threatened legal proceeding to which the Company is a party, or is 
likely to become a party, including those proceedings identified in this Note 18, will have a material adverse effect on its 
business, results of operations, cash flows or financial condition. The costs incurred by the Company to defend lawsuits, 
investigations and claims and amounts the Company pays to other parties because of these matters may be covered by insurance 
in some circumstances.   
 
Litigation and Commercial Claims  
 
The Company and a subsidiary of the Company, Mistras Arizona Inspection Services LLC (“Mistras Arizona”), are subject to a 
lawsuit filed by the State of Arizona and the Arizona Department of Environmental Quality (collectively “DEQ”). The lawsuit, 
captioned State of Arizona v. Mistras Group, Inc., Mistras Arizona Inspection Services, LLC and Naiman Phoenix, Ltd., was 
originally filed on February 27, 2024, in the Superior Court of the State of Arizona for Maricopa County, CV 2024-003866 (the 
"DEQ Complaint"). The DEQ Complaint alleges various violations of Arizona environmental laws and regulations by the 
Company and Mistras Arizona in connection with the operation by Mistras Arizona of its testing facility in Phoenix, Arizona. 

Table of Contents 
89 
The DEQ Complaint seeks, through injunctive relief, the closing of a chromic acid plating line at the testing facility, 
implementation of a site assessment plan approved by the DEQ, and corrective and remedial action to bring the testing facility 
into compliance with laws and regulations. In addition, the DEQ Complaint seeks unspecified penalties and costs.  
 
The Superior Court held a hearing September 2024 regarding the DEQ’s request for a preliminary injunction. On October 23, 
2024, the Superior Court issued a ruling, which declined to issue the preliminary injunction requested by the DEQ, but imposed 
the following conditions on the Company and Mistras Arizona unless and until modified by the Superior Court or entry of a 
final judgement: (1) the Company and Mistras Arizona are prohibited from releasing or permitting any release of chromic acid 
from the facility; (2) within a reasonable time, the Company and Mistras Arizona must complete improvements to the testing 
facility designed to prevent future discharges of chromium or chromic acid; (3) the Company must notify the DEQ upon 
completion of the improvement to enable the DEQ to conduct an inspection; and (4) the Company and Mistras Arizona are 
prohibited from engaging in any chrome plating operations at the testing facility until they notify the DEQ that the 
improvements have been completed. The DEQ may seek relief if it determines that the improvements are not sufficient to 
prevent discharges. 
 
The Company intends to comply with the Superior Court's ruling. This matter is still in the relatively early stages, including as 
to factual and expert discovery. It is probable that remediation costs, fines and penalties may be imposed related to this lawsuit. 
However, the Company is unable to estimate the range of loss that it may incur.   
 
In addition, Mistras Arizona’s operations in Phoenix are located at a leased site within the footprint of the Motorola 52nd Street 
Superfund Site (the “Motorola Site”). Mistras Arizona received a General Notice Letter from the US Environmental Protection 
Agency (the "EPA"), dated May 21, 2024, informing Mistras Arizona that the EPA has identified it as a potentially responsible 
party in relation to the Motorola Site. 
 
Pension Related Contingencies 
 
Certain of Company’s subsidiaries had significant reductions in their unionized workers in 2018. The collective bargaining 
agreements for the employees of this subsidiary required contributions for these employees to two national multi-employer 
pension funds. The reduction in employees resulted in one of the Company's subsidiaries incurring a complete withdrawal to 
one of the pension funds under the Employee Retirement Income Security Act of 1974 ("ERISA"), which was fully satisfied in 
2019. The Company has determined that the subsidiary is likely to incur partial or complete withdrawal liability to the other 
pension fund. The balance of the estimated total amount of this potential liability as of December 31, 2024 is approximately 
$2.5 million, which was incurred in 2018 and 2019. 
 
  
19. Segment Disclosure 
  
The Company’s three operating segments, which are also the Company's reportable segments, are: 
  
• 
North America. This segment provides asset protection solutions predominantly in North America, with the largest 
concentration in the United States, followed by Canada, consisting primarily of NDT, inspection, mechanical and 
engineering services that are used to evaluate the safety, structural integrity and reliability of critical energy, industrial 
and public infrastructure and commercial aerospace components. Software, digital and data services are included in 
this segment. 
 
• 
International. This segment offers services, products and systems similar to those of the other segments to select 
markets within Europe, the Middle East, Africa, Asia and South America, but not to customers in China and South 
Korea, which are served by the Products and Systems segment. 
 
• 
Products and Systems. This segment designs, manufactures, sells, installs and services the Company’s asset protection 
products and systems, including equipment and instrumentation, predominantly in the United States. 

Table of Contents 
90 
 
Costs incurred for general corporate services, including finance, legal, and certain other costs that are provided to the segments 
are reported within Corporate and eliminations. Sales to the International segment from the Products and Systems segment and 
subsequent sales by the International segment of the same items are recorded and reflected in the operating performance of both 
segments. Additionally, engineering charges and royalty fees charged to the North America and International segments by the 
Products and Systems segment are reflected in the operating performance of each segment. 
 
The chief operating decision maker ("CODM") reviews financial information at the operating segment level to allocate 
resources and to assess the operating results and financial performance for each operating segment. For the year ended  
December 31, 2024, our CODM was identified as Manny Stamatakis, the Interim Chief Executive Officer, because he has final 
authority over performance assessment and resource allocation decisions. Beginning January 1, 2025, our CODM was 
identified as Natalia Shuman, upon her appointment as our Chief Executive Officer effective January 1, 2025, as she has final 
authority over performance assessment and resource allocation decisions. Our segments are based on the type and concentration 
of customers served, service requirements, methods of distribution and major product lines. 
 
Segment income (loss) from operations is the primary performance measure used by the CODM to evaluate segment 
performance and allocate resources, including considering budget-to-actual variances and prior year-to-actual variances on a 
monthly basis in accordance with GAAP under ASC 280, Segment Reporting. Segment income (loss) from operations for each 
of the Company's reportable segments are comprised of revenue, selling, general & administrative expenses, and "other 
expenses." "Other expenses" include cost of revenue, bad debt provision for troubled customers, goodwill impairment charges, 
reorganization and environmental costs, legal settlements and recoveries, acquisition-related expenses, depreciation and 
amortization and research and engineering.  
 
Corporate and other assets are comprised principally of cash, deposits, property, plant and equipment, domestic deferred taxes, 
deferred charges and other assets. Corporate loss from operations consists of administrative charges related to corporate 
personnel and other charges that cannot be readily identified for allocation to a particular segment. These items of our operating 
profit are managed centrally at the corporate level and are excluded from the measure of segment income reviewed by the 
CODM, as well as the measure of segment performance used for incentive compensation purposes. 
  
The accounting policies of the reportable segments are the same as those described in Note 1-Summary of Significant 
Accounting Policies and Practices.   
  
Selected consolidated financial information by segment for the periods shown was as follows. Income (loss) from operations by 
operating segment includes intercompany transactions, which are eliminated in Corporate and eliminations.

The tables above only reconcile to income (loss) from operations as our measure of segment profitability and the remainder of 
the reconciliation to net income (loss) can be seen on the Consolidated Statement of Income (Loss). For the year ended 
December 31, 2024, Products and Systems segment revenue was comprised of approximately $4.0 million of sales to the 
International segment, which was eliminated upon consolidation. Intersegment revenue related to sales between other segments 
was immaterial for the years ended December 31, 2024, 2023, and 2022.

Table of Contents 
93 
our Senior Executive Vice President and Chief Financial Officer concluded that, as of December 31, 2024, our disclosure 
controls and procedures were effective. 
 
Management’s Report on Internal Control Over Financial Reporting 
  
Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as defined in 
Rules 13a-15(f) and 15d-15(f) under the Exchange Act. Our internal control over financial reporting is a process designed by, or 
under the supervision of, our Chairman and Interim President and Chief Executive Officer and our Senior Executive Vice 
President and Chief Financial Officer, and effected by our Board, management and other personnel 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.  
  
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 policies or procedures may deteriorate. 
  
Our management assessed the effectiveness of our internal control over financial reporting as of December 31, 2024. In making 
this assessment, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway 
Commission (COSO) in the updated Internal Control — Integrated Framework issued in 2013. Based on that assessment, our 
management concluded that, as of December 31, 2024, our internal control over financial reporting was effective. 
  
The effectiveness of our internal control over financial reporting as of December 31, 2024, has been audited by 
PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in their report which appears herein. 
 
Changes in Internal Control over Financial Reporting 
  
There has been no change in our internal control over financial reporting during the quarter ended December 31, 2024, that has 
materially affected, or is reasonably likely to materially affect, our internal control over financial reporting. 
 
Item 9B.   OTHER INFORMATION 
  
During the three months ended December 31, 2024, none of the Company’s directors or officers (as defined in Rule 16a-1(f) of 
the Exchange Act) adopted, terminated or modified a Rule 10b5-1 trading arrangement or non-Rule 10b5-1 trading arrangement 
(as such terms are defined in Item 408 of Regulation S-K of the Securities Act). During the three months ended December 31, 
2024, the Company did not adopt, terminate or modify a Rule 10b5-1 trading arrangement.
