Our customers include some of the largest natural gas processors, transmission and distribution companies, refineries, power generators, industrial manufacturing, engineering and construction companies, semiconductor manufacturers, compressor manufacturers, beverage can manufacturers, metals and minerals, and electric vehicle producers in the world.

We believe our value differentiators include, but are not limited to, our product and solutions performance quality, reliability, durability, on-time delivery and safety, all of which are underpinned by our core capabilities in advanced design and systems engineering, commercial excellence, and operational excellence. We believe these differentiators and core capabilities are critical to maintaining our competitive position. Additionally, we have built a spirit of continuous improvement to ensure we maintain our market leadership position.

With an installed base of operating systems and equipment in excess of $6 billion, we are targeting to grow a higher share of recurring revenue from aftermarket products and installed base value-added services, which we believe will provide a greater customer retention and loyalty, and increased business resiliency.

Industry Overview

We serve a growing multi-billion dollar global industrial market that is highly fragmented and comprised of many industrial sectors and niche applications. Our legacy sectors include industrial wastewater treatment, industrial ventilation systems and contamination controls and filtration, semiconductor fabrication, electronics manufacturing, baseload and backup power generation, hydrocarbon processing, chemical processing, natural gas processing and transport, automobile and aircraft production, polysilicon production, battery recycling, metals processing and production, and produced water treatment. Emerging sectors and applications include electric vehicle and battery production, desalination water transport, ultra-high purity water treatment for electrolysis and electronics production, naval/marine vessel oily water treatment, aluminum beverage can production, and lightweight, high-strength metals production.

We believe demand for our products and services will continue to be driven by the following factors:

These factors, individually or collectively, tend to drive increases in industrial capital spending that are not directly impacted by general economic conditions. In contrast, favorable conditions in the economy generally lead to plant expansions and the construction of new industrial sites. However, in a weak economy, customers tend to lengthen the time from initial inquiry to the purchase order or may elect to defer purchases.

Mission and Strategy

Our mission is to help companies grow their business with safe, clean and more efficient solutions that help protect their people, the environment and their industrial equipment and facilities.

We seek to fulfill this mission by providing leading solutions for niche, engineered applications in industrial air treatment and management, industrial water treatment, and the energy transition. We will continue to leverage our technologies and application expertise for customers around the world.

Our strategy to become a global leader in niche applications in industrial air treatment and management, industrial water treatment, and the energy transition is supported by an operating environment of performance excellence across the Company.

We constantly look for opportunities to apply our technology and expertise to new customers and in new geographies in our existing end markets, and to enter new end markets with our existing set of products and solutions. Acquisitions are a key part of our growth model and we constantly are seeking out value-added, accretive additions to the CECO portfolio aligned with our strategic focus in industrial air, industrial water and the energy transition.

We intend to continue to expand our customer base and end markets and have continued to pursue potential attractive growth opportunities both domestically and internationally.

Business Segments

Our reportable segments continue to be focused on attractive end markets and each segment is aligned to generate profitable growth for the Company with a compelling technology and solution set to benefit customers.

Competitive Strengths

Leading market position as a complete solution provider

We believe we are a leading provider of critical solutions in industrial air quality, industrial water treatment, and energy transition solutions. The multi-billion dollar global market is highly fragmented with numerous small and regional contracting firms separately supplying engineering services, fabrication, installation, testing and monitoring, products and spare parts. We offer our customers a complete end-to-end solution, including engineering and project management services, procurement and fabrication, construction and installation, aftermarket support, and sale of consumables, which allows our customers to avoid dealing with multiple vendors when managing projects.

Long-standing experience and customer relationships in growing industry

We have serviced the needs of our target markets for over 50 years. Our extensive experience and expertise in providing diversified solutions enhances our overall customer relationships, and provides us with a competitive advantage in our markets relative to other companies in the industry. We believe this is evidenced by strong relationships with many of our world-class customers. We believe no single competitor has the resources to offer a similar portfolio of product and service capabilities. We offer the depth of a large organization, while our lean organizational structure keeps us close to our customers and markets, allowing us to offer rapid and complete solutions in each unique situation.

Diversified equipment and solution portfolio and broad customer base

The global diversity of our offering and footprint and customer base provides us with multiple growth opportunities. We have a diversified customer base across a range of industries. We believe that the diversity of our customers, solutions, and end markets mitigates our risk of a potential fluctuation or downturn in demand from any individual industry or particular customer. We believe we have the resources and capabilities to meet the needs of our customers as they upgrade and expand domestically as well as into new international markets. Once systems have been installed and a relationship has been established with the customer, we are often awarded repetitive service and maintenance business as the customers’ processes change and modifications or additions to their systems become necessary.

Experienced management and engineering team

Our business management team has substantial experience in delivering highly-engineered solutions for industrial air quality, industrial water treatment, and energy transition applications. The collective experience of our teams enables us to pursue our strategy, and to successfully execute on our strategic and growth priorities. Our team includes approximately 400 engineers, designers, solution experts, and project managers whose industry experience and technical expertise enables them to have a deep understanding of the solutions that will best suit the needs of our customers. The experience and stability of our senior management, operating and engineering teams have been crucial to our recent growth and to developing and maintaining customer relationships, and increasing our market position.

Innovative solutions

We leverage our engineering and manufacturing expertise, fabrication partner network, and strong customer relationships to develop and deliver new products and solutions to address the identified needs of our customers or a particular end market. We thoroughly analyze each new opportunity by considering projected demand, pricing, and cost to deliver, and only pursue those opportunities that we believe will contribute to sustainable earnings growth. In addition, we seek to continually improve our legacy technologies, solutions, and applications with the aim to maintain competitiveness in our existing customer segments, and to adapt them to new industries and customers.

Disciplined acquisition program with successful integration

We believe that we have demonstrated an ability to successfully acquire and integrate companies with complementary product or service offerings. We will continue to seek and execute additional strategic acquisitions and focus on expanding our solution and product breadth and reach, as well as entering into adjacent customer segments and applications. We believe that the breadth and diversity of our products and services and our ability to deliver full solutions to various end markets provides us with multiple sources of stable growth, relative scale benefits, and a competitive advantage relative to other players in the industry, and we will continue to reinforce this advantage.

Products and Services

We provide a wide range of engineered and configured products and solutions including dampers and diverters, expansion joints, selective catalytic reduction systems, severe-service and industrial cyclones, dust collectors, thermal oxidizers, filtration systems, wet and dry scrubbers, separators and coalescers, water treatment packages, metallic and non-metallic pumps, industrial silencers and fluid handling equipment, and plant engineering services and engineered design build fabrication. Our products and solutions primarily compete on the basis of performance, track record, speed of delivery, quality, price and customer service.

Project Design and Research and Development

Our strategy is to produce and supply differentiated, specialized or configured products and solutions that are often tailored to the specifications of a customer or application. We start by understanding our customers’ needs, then by focusing our new product development efforts on those criteria that help protect our shared environment while improving a variety of operational outcomes including, but not limited to, facility uptime, production quality, employee safety, equipment protection and process performance.

We continually collaborate with our customers on projects to ensure the proper solution and customer satisfaction. The project development cycle may follow many different paths depending on the specifics of the job and end market. The cycle can take from one to more than twelve months from concept and design to production but may vary significantly depending on developments that occur during the process, including among others, the emergence of new environmental demands, changes in design specifications and ability to obtain necessary approvals.

Sales, Marketing and Support

Our global commercial strategy is to provide a solutions-based approach for our customers, which may take on the role of single source provider of technology, products and equipment for a particular project. When called upon, this strategy involves expanding our scope of supply by utilizing our portfolio of in-house technologies and those of third-party equipment suppliers, many of which have been long-standing partners evolved from pure supplier roles to value-added business partners. Where we identify a technology that is a critical element or commonly required for a solution, we will consider acquiring such technology to ensure we have the appropriate degree of strategic control. This enables us to leverage existing business with selective alliances of suppliers and application specific engineering expertise. Our value proposition to our customers is to provide competitively priced, customized solutions that leverage our vast project experience base and design library. Our industry-specific knowledge, accompanied by our product and service offerings, provides valuable benefits for our customers and synergies across our network of partners.

We sell and market our products and services with our own direct sales force in key regions including the United States, the Netherlands, United Kingdom, Canada, United Arab Emirates, India, China, Korea, and Singapore. Our direct sales and business development teams will work in conjunction with outside sales representatives in the North America, South America, Europe, Middle East, Southeast and East Asia, and India regions, when appropriate. We expect to continue expanding our sales and support capabilities and our network of outside sales representatives in key regions domestically and internationally.

We market our offerings to our customers through a variety of channels including, but not limited to, digital, web, social media, email campaigns, individual customer visits, product announcements, brochures, magazine articles, advertisements and cover or article features in trade journals and other publications. We also participate in public relations and promotional events, including industry tradeshows and technical conferences.

Our customer service organization and sales force provides our customers with technical assistance, use and maintenance information as well as other key information regarding their purchase. We also actively provide our customers with access to key information regarding changes and pending changes in environmental regulations as well as new product or service developments. We believe that maintaining a close relationship with our customers and providing them with the support they request improves their level of satisfaction and enables us to foresee their potential future product needs or service demands. Moreover, this approach can lead to sales of annual service and support contracts as well as consumables. Our website also provides our customers with online tools and technical resources.

Quality Assurance

In engineered systems, quality is defined as system performance. We review with our customers, before the contract is signed, the technical specification and the efficiency of the equipment that will be customized to meet their specific needs. We then review these same parameters internally to assure that warranties will be met. Standard project management and production management tools are used to help ensure that all work is done to specification and that project schedules are met. Equipment is tested at the site to ensure it is functioning properly.

Customers

We are not dependent upon any single customer, and no customer contributed 10% or more of our consolidated revenues for the years ended December 31, 2023, 2022, or 2021.

Suppliers and Subcontractors

We purchase our raw materials and supplies from a variety of global sources. When possible, we directly secure iron and steel sheet and plate products from steel mills, whereas other materials are purchased from a variety of steel service centers. Steel prices have traditionally been volatile, but we typically mitigate the risk of higher prices by including a “surcharge” on our standard products and tracking major materials industry indices and projections. On contract work, we try to mitigate the risk of higher prices by including the current price in our estimate and generally include price inflation clauses for protection.

Typically, on turnkey projects, we subcontract manufacturing, electrical work, concrete work, controls, conveyors and insulation. We use subcontractors with whom we have good working relationships and review each project at the beginning and on an ongoing basis to help ensure that all work is being done according to our specifications. Subcontractors are generally paid when we are paid by our customers according to the terms of our contract with the customer. Our business model focuses on effective management of subcontractors and flow of raw and finished materials, which allows us to optimize working capital levels through reduction in certain assets and reduce capital expenditures.

While we believe we have a good relationship with our suppliers and subcontractors, we are currently experiencing shortages of raw materials and inflationary pressures for certain materials and labor. We expect these supply chain challenges and cost impacts to continue for the foreseeable future as markets continue to recover and supply chains further normalize. Although we have secured raw materials from existing and alternate suppliers and have taken other mitigating actions to mitigate supply disruptions, we cannot guarantee that we can continue to do so in the future. In this event, our business, results and financial condition could be adversely affected.

Backlog

Backlog (i.e., unfulfilled or remaining performance obligations) represents the sales we expect to recognize for our products and services for which control has not yet transferred to the customer. Backlog was $370.9 million as of December 31, 2023 as compared to $311.7 million as of December 31, 2022, an increase of $59.2 million or 19.0%. Backlog is adjusted on a quarterly basis for fluctuations in foreign currency exchange rates. Substantially all backlog is expected to be delivered within 18 months, with a majority within 12 months. Backlog is not defined by United States generally accepted accounting principles ("GAAP") and our methodology for calculating backlog may not be consistent with methodologies used by other companies.

Competition

The markets we serve are highly fragmented with numerous small and regional participants. We believe no single company competes with us across the full range of our solutions and products. Competition in the markets we serve is based on a number of considerations, including past performance, track record, customer approvals, lead times, technology, applications experience, know-how, reputation, product warranties, service and price. Demand for our product can vary period over period depending on conditions in the markets we serve. We believe our product performance and quality, reliability, durability, on-time delivery, and safety supported by advanced engineering and operational excellence differentiate us from many of our competitors, including those competitors who often offer products at a lower price.

Due to the size and shipping weight of many of our projects, localized manufacturing/fabrication capabilities are very important to our customers. As a result, competition varies widely by region and industry. The market for our engineered products is reasonably competitive and is characterized by technological stability, continuously evolving environmental regulations, and increasing customer requirements. We believe that the additional competitive factors in our markets include:

We believe we compete favorably with respect to these factors.

Government Regulations

We believe our operations are in compliance with applicable environmental laws and regulations. We believe that changes in environmental laws and regulations create opportunity given the nature of our business.

Our business is subject to numerous evolving laws and regulations. While there are not currently regulations proposed or pending that we believe will result in material capital, operating or other costs to the business at this time, such regulations could be proposed and/or passed into law in 2024 or beyond. Other regulations currently in place could be withdrawn and replaced with more stringent

requirements in 2024 or beyond. New laws and regulations and the costs of compliance with such new laws and regulations can only be broadly appraised until their implementation becomes more defined through regulatory guidance and enforcement.

Intellectual Property

We rely on a combination of patent, trademark, copyright and trade secret laws, employee and third-party nondisclosure/confidentiality agreements and license agreements to protect our intellectual property. We sell most of our products under a number of registered trade names, brand names and registered trademarks, which we believe are widely recognized in the industry. While we hold patents within a number of our businesses, we do not view our patents to be material to our business.

Human Capital Management

We have employees located throughout the globe. As of December 31, 2023, CECO had approximately 1,200 employees, across nine countries. Of our US employees, 131 are unionized in our Pennsylvania, Tennessee and North Carolina facilities. Outside the United States, we enter into employment contracts and agreements in those countries in which such relationships are mandatory or customary. The provisions of these agreements correspond in each case with the required or customary terms in the subject jurisdiction. We have historically maintained good employee relations and have successfully concluded all of our recent negotiations without a work stoppage. However, we cannot predict the outcome of future contract negotiations.

Our strong employee base, along with our uncompromising commitment to our values of customer first, accountability, relentless execution, respect, integrity and teamwork, provide the foundation of our company’s success. Employee safety and managing the risks associated with our workplace, is of paramount importance to CECO. We believe that all injuries, occupational illnesses and incidents are preventable, and we are committed to operating with a zero-incident culture. Through our environmental, health and safety program we implement policies and training programs, as well as perform self-audits, to ensure our colleagues leave the workplace safely every day. To better understand employee safety at the site level, we have safety committees and safety scorecards to share best practices between sites. CECO’s foundational commitment to safety is demonstrated by our world-class recordable and loss time rates. We currently share scorecard information monthly with our team members to foster visibility, accountability and commitment across our workplace, communicating and celebrating successful results across the enterprise. In addition to lagging indicators, such as injury performance, the scorecards highlight leading indicators such as safety observations and near-misses, as well as other proactive actions taken at each site to ensure worker safety. For the year ended December 31, 2023, CECO’s domestic Total Recordable Incident Rate (“TRIR”) was 1.5% as compared to our benchmark industry average TRIR of 4.3%.

We believe a diverse and inclusive workforce is critical to inspiring innovative thinking, creative problem-solving, performance, and results, so we cultivate an environment where team members feel valued, engaged, and inspired to give their best. The unique characteristics that shape each individual help inform our decisions as a company, and this mindset allows CECO to realize new opportunities and add value to our customers, partners, and stockholders.

As part of our efforts to expand CECO’s diverse workforce, we:

CECO’s commitment to expanding our diverse workforce and enhancing our inclusive culture is driven by our recognition that a workplace that is reflective of our global customer base establishes a firm foundation to drive creativity and innovation, which leads to problem solving, development, performance, and profitable business success.

We invest in programs and processes that develop our employees’ capabilities to ensure that we have the talent we need to execute our strategic business plans. Our Performance Management Program ensures that all leaders have clear priorities, and that their performance relative to these priorities is linked to their total rewards package. We conduct an annual code of conduct training that includes subject matter areas of: anti-corruption, discrimination, harassment, data privacy, appropriate use of company assets, protecting confidential information and how to report code violations. Each employee takes this annual training and follow up communications are conducted to ensure completion of the course by all employees. We also timely completed our mandated sexual harassment training courses with the specified employees.

We believe our management team has the experience necessary to effectively execute our strategy. Our platform leaders have significant industry experience and are supported by an experienced and talented management team who is dedicated to maintaining

and expanding our position as a global leader in our markets. For discussion of the risks related to attracting and retention of management and executive employees, refer to “Part I, Item 1A. Risk Factors” of this Annual Report on Form 10-K.

Item 1A. Risk Factors

An investment in our securities involves a high degree of risk. You should carefully consider the risk factors described below, together with the other information included in this Annual Report on Form 10-K, before you decide to invest in our securities. The risks described below are the material risks of which we are currently aware; however, they may not be the only risks that we may face. Additional risks and uncertainties not currently known to us or that we currently view as immaterial may also impair our business. Although the risks are organized by headings, and each risk is discussed separately, many are interrelated. If any of these risks develop into actual events, it could materially and adversely affect our business, financial condition, results of operations and cash flows, and the trading price of your shares could decline and you may lose all or part of your investment.

Risks Related to Our Business and Industry

Our business may be adversely affected by global economic conditions.

A national or global economic downturn or credit crisis may have a significant negative impact on our financial condition, future results of operations and cash flows. Specific risk factors related to these overall economic and credit conditions include the following:

These risk factors could reduce our product sales, increase our operating costs, impact our ability to collect customer receivables, lengthen our cash conversion cycle and increase our need for cash, which would ultimately decrease our profitability and negatively impact our financial condition. They could also limit our ability to expand through acquisitions due to the tightening of the credit markets.

Our dependence upon fixed-price contracts could adversely affect our operating results.

The majority of our projects are currently performed on a fixed-price basis, while a limited number of projects are currently performed on a time and materials basis. Under a fixed-price contract, we agree on the price that we will receive for the entire project, based upon a defined scope, which includes specific assumptions and project criteria. If our estimates of the costs to complete the project are below the actual costs that we incur, our margins will decrease, or we may incur a loss. The revenue, cost and gross profit realized on a fixed-price contract will often vary from the estimated amounts because of unforeseen conditions or changes in job conditions and variations in labor and equipment productivity over the term of the contract. While our fixed-price contracts are typically not individually material to our operating results, if we are unsuccessful in mitigating these risks, we may realize gross profits that are different from those originally estimated and incur reduced profitability or losses on projects. Depending on the size of a project, these variations from estimated contract performance could have a significant effect on our operating results. In general, turnkey contracts to be performed on a fixed-price basis involve an increased risk of significant variations. Generally, our contracts and projects vary in length, depending on the size and complexity of the project, project owner demands and other factors. The foregoing risks are exacerbated for projects with longer-term durations and the inherent difficulties in estimating costs and of the interrelationship of the integrated services to be provided under these contracts whereby unanticipated costs or delays in performing part of the contract can have compounding effects by increasing costs of performing other parts of the contract.

Accounting for contract revenue may result in material adjustments that would adversely affect our financial condition and results of operations.

We derive a significant portion of our revenues from fixed price contracts. We recognize revenue as performance obligations are satisfied and the customer obtains control of the products and services. A significant amount of our revenue is recognized over a period of time as we perform under the contract because control of the work in process transfers continuously to the customer. For performance obligations to deliver products with continuous transfer of control to the customer, revenue is recognized based on the extent of progress towards completion of the performance obligation. Progress is measured based on the ratio of costs incurred to date to the total estimated costs to complete the performance obligation. For these contracts, the cost-to-cost measure best depicts the continuous transfer of goods or services to the customer.

Contract revenue and total direct cost estimates are reviewed and revised periodically as the work progresses and as change orders are approved, and adjustments are reflected in contract revenue in the period when these estimates are revised. These estimates are based

on management’s reasonable assumptions and our historical experience, and are only estimates. Variation of actual results from these assumptions, which are outside the control of management and can differ from our historical experience, could be material. To the extent that these adjustments result in an increase, a reduction or the elimination of previously reported contract revenue, we would recognize a credit or a charge against current earnings, which could be material.

Our inability to deliver our backlog on time could affect our future sales and profitability, and our relationships with our customers.

Our backlog was $370.9 million at December 31, 2023 and $311.7 million at December 31, 2022. Our ability to meet customer delivery schedules for our backlog is dependent on a number of factors including, but not limited to, access to the raw materials required for production, an adequately trained and capable workforce, project engineering expertise for certain large projects, sufficient internal manufacturing plant capacity, available subcontractors and appropriate planning and scheduling of manufacturing resources. Our failure to deliver in accordance with customer expectations may result in damage to existing customer relationships and result in the loss of future business. Failure to deliver backlog in accordance with expectations could negatively impact our financial performance and cause adverse changes in the market price of our common stock.

Volatility of oil and natural gas prices can adversely affect demand for our products and services.

Volatility in oil and natural gas prices can impact our customers’ activity levels and spending for our products and services. Current energy prices are important contributors to cash flow for our customers and their ability to fund capital expenditures. Lower oil and natural gas prices generally lead to decreased spending by our customers. While higher oil and natural gas prices generally lead to increased spending by our customers, sustained high energy prices can be an impediment to economic growth, and can therefore negatively impact spending by our customers. Our customers also take into account the volatility of energy prices and other risk factors by requiring higher returns for individual projects if there is a higher perceived risk. Any of these factors could affect the demand for oil and natural gas and could have a material effect on our results of operations.

Increasing costs for manufactured components, raw materials, transportation, health care and energy prices may adversely affect our profitability.

We use a broad range of manufactured components and raw materials in our products, including raw steel, steel-related components, resin, filtration media and equipment such as fans and motors. Materials, wages and subcontracting costs comprise the largest components of our total costs, and increases in the price of these items could materially increase our operating costs and materially adversely affect our profit margins. Similarly, transportation, steel and health care costs have risen steadily over the past few years and could represent an increasing burden for us. Although we try to contain these costs whenever possible, and although we try to pass along increased costs in the form of price increases to our customers, we may be unsuccessful in doing so, and even when successful, the timing of such price increases may lag significantly behind our incurrence of higher costs.

Our financial performance may vary significantly from period to period.

Our annual revenues and earnings have varied in the past and are likely to vary in the future. Our contracts generally stipulate customer-specific delivery terms and may have contract cycles of a year or more, which subjects these contracts to many factors beyond our control. In addition, contracts that are significantly larger in size than our typical contracts tend to intensify their impact on our annual operating results. Furthermore, as a significant portion of our operating costs are fixed, an unanticipated decrease in our revenues, a delay or cancellation of orders in backlog, or a decrease in the demand for our products, may have a significant impact on our annual operating results. Therefore, our annual operating results may be subject to significant variations and our operating performance in one period may not be indicative of our future performance.

Customers may cancel or delay projects. As a result, our backlog may not be indicative of our future revenue.

Customers may cancel or delay projects for reasons beyond our control. Our orders normally contain cancellation provisions that permit us to recover our costs, and, for most contracts, a portion of our anticipated profit in the event a customer cancels an order. If a customer elects to cancel an order, we may not realize the full amount of revenues included in our backlog. If projects are delayed, the timing of our revenues could be affected and projects may remain in our backlog for extended periods of time. Revenue recognition occurs over long periods of time and is subject to unanticipated delays. If we receive relatively large orders in any given quarter, fluctuations in the levels of our quarterly backlog can result because the backlog in that quarter may reach levels that may not be sustained in subsequent quarters. As a result, our backlog may not be indicative of our future revenues. With rare exceptions, we are not issued contracts until a customer is ready to start work on a project. Thus, it is our experience that the only relationship between the length of a project and the possibility that a project may be cancelled is simply the fact that there is more time involved. For example, in a year-long project as opposed to a three-month project, more time is available for the customer to experience a softening in its business, which may cause the customer to cancel a project.

We face significant competition in the markets we serve.

All of the product and solution categories in which we compete are highly fragmented and competitive. We compete in industrial markets against a number of local, regional and national manufacturers and suppliers in each of our product or service lines. Our products primarily compete on the basis of performance, quality, reliability, lead time, on-time delivery, and safety supported by advanced engineering and operational excellence. We must also be responsive to any technological developments, including expanded use of data analytics, artificial intelligence, and machine learning, and related changing customer requirements. Any failure by us to compete effectively in the markets we serve could have a material adverse effect on our financial condition, results of operations and cash flows.

We may incur material costs as a result of existing or future product liability claims, or other claims and litigation that could adversely affect our financial condition, results of operations and cash flows; and our insurance coverage may not cover all claims or may be insufficient to cover the claims.

Despite our quality assurance measures, we may be exposed to product liability claims, other claims and litigation in the event that the use of our products results, or is alleged to result, in bodily injury and/or property damage or our products actually or allegedly fail to perform as expected. Such claims may also be accompanied by fraud and deceptive trade practices claims. While we maintain insurance coverage with respect to certain product liability and other claims, we may not be able to obtain such insurance on acceptable terms in the future, if at all, and any such insurance may not provide adequate coverage against product liability and other claims. Furthermore, our insurance may not cover damages from breach of contract by us or based on alleged fraud or deceptive trade practices. Any future damages that are not covered by insurance or are in excess of policy limits could have a material adverse effect on our financial condition, results of operations and cash flows. In addition, product liability and other claims can be expensive to defend and can divert the attention of management and other personnel for significant periods of time, regardless of the ultimate outcome.

An unsuccessful defense of a product liability or other claim could have an adverse effect on our financial condition, results of operations and cash flows. Even if we are successful in defending against a claim relating to our products, claims of this nature could cause our customers to lose confidence in our products and us.

Liability to customers under warranties may adversely affect our reputation, our ability to obtain future business and our results of operations.

We provide certain warranties as to the proper operation and conformance to specifications of the products we manufacture or produce. Failure of our products to operate properly or to meet specifications may increase our costs by requiring additional engineering resources and services, replacement of parts and equipment or monetary reimbursement to customers. We have in the past received warranty claims, are currently subject to warranty claims, and we expect to continue to receive warranty claims in the future. To the extent that we incur substantial warranty claims in any period, our reputation, our ability to obtain future business and our results of operations could be adversely affected.

Risks Related to our Business Model and Capital Structure

Our gross profit may be affected by shifts in our product mix.

Certain of our products have higher gross profit margins than others. Consequently, changes in the product mix of our sales from quarter-to-quarter or from year-to-year can have a significant impact on our reported gross profit margins. Certain of our products also have a much higher internally manufactured cost component. Therefore, changes from quarter-to-quarter or from year-to-year can have a significant impact on our reported gross profit margins. In addition, contracts with a higher percentage of subcontracted work or equipment purchases may result in lower gross profit margins.

Our manufacturing operations are dependent on third-party suppliers.

Although we are not dependent on any one supplier, we are dependent on the ability of our third-party suppliers to supply our raw materials, as well as certain specific component parts and sub-assemblies. The third-party suppliers upon which we depend may default on their obligations to us due to bankruptcy, insolvency, lack of liquidity, adverse economic conditions, operational failure, fraud, loss of key personnel, health-related shutdowns, or other reasons. We cannot ensure that our third-party suppliers will dedicate sufficient resources to meet our scheduled delivery requirements or that our suppliers will have sufficient resources to satisfy our requirements during any period of sustained demand. Failure of suppliers to supply, or delays in supplying, our raw materials or certain components, or allocations in the supply of certain high demand raw components, for any reason, including, without limitation, disruptions in our suppliers’ due to cybersecurity incidents, terrorist activity, public health crises, fires or other natural disasters could

materially adversely affect our operations and ability to meet our own delivery schedules on a timely and competitive basis. Additionally, our third-party suppliers may provide us with raw materials or component parts that fail to meet our expectations or the expectations of our customers, which could subject us to product liability claims, other claims and litigation.

Our use of subcontractors could potentially harm our profitability and business reputation.

Occasionally we act as a prime contractor in some of the projects we undertake. In our capacity as lead provider, and when acting as a prime contractor, we perform a portion of the work on our projects with our own resources and typically subcontract activities such as manufacturing, electrical work, concrete work, insulation, conveyors and controls. In our industry, the lead contractor is normally responsible for the performance of the entire contract, including subcontract work. Thus, when acting as a prime contractor, we are subject to risk associated with the failure of one or more subcontractors to perform as anticipated.

We employ subcontractors at various locations around the world to meet our customers’ needs in a timely manner, meet local content requirements and reduce costs. Subcontractors generally perform the majority of our manufacturing for international customers. We also utilize subcontractors in North America. The use of subcontractors decreases our control over the performance of these functions and could result in project delays, escalated costs and substandard quality. These risks could adversely affect our profitability and business reputation. In addition, many of our competitors use the same subcontractors that we use and could potentially influence our ability to hire these subcontractors. If we were to lose relationships with key subcontractors, our business could be adversely impacted.

A significant portion of our accounts receivable are related to larger contracts, which increases our exposure to credit risk.

Significant portions of our sales are to customers who place large orders for custom products and whose activities are related to the power generation and oil and gas industries. As a result, our exposure to credit risk is affected to some degree by conditions within these industries and governmental and or political conditions. We frequently attempt to reduce our exposure to credit risk by requiring progress or milestone payments and letters of credit as well as closely monitoring the credit worthiness of our customers. However, the continuing economic climate and other unanticipated events that affect our customers could have a materially adverse impact on our operating results.

Changes in billing terms can increase our exposure to working capital and credit risk.

Our products are generally sold under contracts that allow us to bill upon the completion of certain agreed upon milestones or upon actual shipment of the product, and certain contracts include a retention provision. We attempt to negotiate progress-billing milestones on all large contracts to help us manage the working capital and credit risk associated with these large contracts. Consequently, shifts in the billing terms of the contracts in our backlog from period to period can increase our requirement for working capital and can increase our exposure to credit risk.

Currency fluctuations may reduce profits on our foreign sales or increase our costs, either of which could adversely affect our financial results.

Given that approximately 33% of our 2023 revenues are outside the United States, we are subject to the impact of fluctuations in foreign currency exchange rates. Although our financial results are reported in U.S. dollars, a portion of our sales and operating costs are realized in foreign currencies. Our sales and profitability are impacted by the movement of the U.S. dollar against foreign currencies in the countries in which we generate sales and conduct operations. Long-term fluctuations in relative currency values could have an adverse effect on our operations and financial conditions.

If our goodwill or indefinite lived intangibles become impaired, we may be required to recognize charges that would adversely impact our results of operations.

As of December 31, 2023, goodwill and indefinite lived intangibles were $220.9 million, or 36.8%, of our total assets. Goodwill and indefinite lived intangible assets are not amortized, but instead are subject to annual impairment evaluations (or more frequently if circumstances require). Major factors that influence our evaluations are estimates for future revenue and expenses associated with the specific intangible asset or the reporting unit in which the goodwill resides. This is the most sensitive of our estimates related to our evaluations. Other factors considered in our evaluations include assumptions as to the business climate, industry and economic conditions. These assumptions are subjective and different estimates could have a significant impact on the results of our analyses. While management, based on current forecasts and outlooks, believes that the assumptions and estimates are reasonable, we can make no assurances that future actual operating results will be realized as planned and that there will not be material impairment charges as a result. In particular, an economic downturn could have a material adverse impact on our customers thereby forcing them to reduce or curtail doing business with us and such a result may materially affect the amount of cash flow generated by our future operations. Any

write-down of goodwill or intangible assets resulting from future periodic evaluations could adversely materially impact our results of operations.

We may incur costs as a result of certain restructuring activities, which may negatively impact our financial results, and we may not achieve some or all of the expected benefits of our restructuring plans.

We are continuously seeking the most cost-effective means and structure to serve our customers, protect our stockholders and respond to changes in our markets. From time to time, we may engage in restructuring activities in an effort to improve cost competitiveness and profitability. We may not achieve the desired or anticipated benefits from these restructuring activities. As a result, restructuring costs may vary significantly from year to year depending on the scope of such activities. Such restructuring costs and expenses could adversely impact our financial results.

We are party to asbestos-containing product litigation that could adversely affect our financial condition, results of operations and cash flows.

Our subsidiary, Met-Pro, along with numerous other third parties, has been named as a defendant in asbestos-related lawsuits filed against a large number of industrial companies including, in particular, those in the pump and fluid handling industries. In management’s opinion, the complaints typically have been vague, general and speculative, alleging that Met-Pro, along with the numerous other defendants, sold unidentified asbestos-containing products and engaged in other related actions that caused injuries (including death) and loss to the plaintiffs. The Company’s insurers have hired attorneys who, together with the Company, are vigorously defending these cases. The Company believes that its insurance coverage is adequate for the cases currently pending against the Company and for the foreseeable future, assuming a continuation of the current volume, nature of cases and settlement amounts. However, the Company has no control over the number and nature of cases that are filed against it, nor as to the financial health of its insurers or their position as to coverage. The Company also presently believes that none of the pending cases will have a material adverse impact upon the Company’s results of operations, liquidity or financial condition.

See Note 12 to the Consolidated Financial Statements contained in Part II, Item 8 of this Annual Report on Form 10-K for information regarding the asbestos-related litigation in which we are involved.

We have $138.6 million of indebtedness as of December 31, 2023, and incurrence of additional indebtedness could adversely affect our ability to operate our business, remain in compliance with debt covenants, make payments on our debt and limit our growth.

Our outstanding indebtedness could have important consequences for investors, including the following:

Our ability to meet our expenses and debt obligations will depend on our future performance, which will be affected by financial, business, economic, regulatory and other factors. We will not be able to control many of these factors. We cannot be certain that our earnings will be sufficient to allow us to pay the principal and interest on our existing or future debt and meet our other obligations. If we do not have enough money to service our existing or future debt, we may be required to refinance all or part of our existing or future debt, sell assets, borrow more money or raise equity. We may not be able to refinance our existing or future debt, sell assets, borrow more money or raise equity on terms acceptable to us, if at all.

Our ability to execute our growth strategies may be limited by our ability to secure and retain additional financing on terms reasonably acceptable to us or at all. Certain of our competitors are larger companies that may have greater access to capital, and therefore may have a competitive advantage over us should our access to capital be limited.

We might be unable to protect our intellectual property rights and our products could infringe the intellectual property rights of others, which could expose us to costly disputes.

Although we believe that our products do not infringe patents or violate the proprietary rights of others, it is possible that our existing patent rights may not be valid or that infringement of existing or future patents or proprietary rights may occur. In the event our products infringe patents or proprietary rights of others, we may be required to modify the design of our products or obtain a license for certain technology. We cannot guarantee that we will be able to do so in a timely manner, upon acceptable terms and conditions, or at all. Failure to do any of the foregoing could have a material adverse effect upon our business. Moreover, if our products infringe patents or proprietary rights of others, we could, under certain circumstances, become liable for damages, which also could have a material adverse effect on our business.

Risks related to our pension plan may adversely impact our results of operations and cash flow.

Significant changes in actual investment return on pension assets, discount rates and other factors may adversely affect our results of operations and pension plan contributions in future periods. GAAP requires that we calculate the income or expense of our plan using actuarial valuations. These valuations reflect assumptions about financial markets and interest rates. We establish the discount rate used to determine the present value of the projected and accumulated benefit obligation at the end of each year based upon the available market rates for high quality, fixed-income investments. An increase in the discount rate would increase future pension expense and, conversely, a decrease in the discount rate would decrease future pension expense. Funding requirements for our pension plan may become more significant. The ultimate amounts to be contributed are dependent upon, among other things, interest rates, underlying asset returns and the impact of legislative or regulatory changes related to pension funding obligations.

We may be subject to substantial withdrawal liability assessments in the future related to multiemployer pension plans to which certain of our subsidiaries make contributions pursuant to collective bargaining agreements.

Under applicable federal law, any employer contributing to a multiemployer pension plan that completely ceases participating in the plan while the plan is underfunded is subject to payment of such employer’s assessed share of the aggregate unfunded vested benefits of the plan. In certain circumstances, an employer can be assessed a withdrawal liability for a partial withdrawal from a multiemployer pension plan. If any of these adverse events were to occur in the future, it could result in a substantial withdrawal liability assessment that could have a material adverse effect on our business, financial condition, results of operations or cash flows.

We have made and may make future acquisitions or divestitures, which involve numerous risks that could impact our financial condition, results of operations and cash flows.

Our operating strategy has involved expanding or contracting our scope of products and services through selective acquisitions or divestitures and the formation or elimination of new business units that are then integrated or separated into or out of our family of turnkey system providers. We have acquired other businesses, product or service lines, assets or technologies that are complementary to our business. We may be unable to find or consummate future acquisitions at acceptable prices and terms. We continually evaluate potential acquisition opportunities in the ordinary course of business.

Although we conduct what we believe to be a prudent level of investigation regarding the operating and financial condition of the businesses, product or service lines, assets or technologies we purchase, an unavoidable level of risk remains regarding their actual operating and financial condition. Until we actually assume operating control of these businesses, product or service lines, assets or technologies, we may not be able to ascertain their actual value or understand potential liabilities. This is particularly true with respect to acquisitions outside the United States.

In addition, acquisitions of businesses may require additional debt or equity financing, resulting in additional leverage or dilution of ownership. Our Credit Facility contains certain covenants that limit, or which may have the effect of limiting, among other things, acquisitions, capital expenditures, the sale of assets and the incurrence of additional indebtedness.

Societal responses to climate change could adversely affect our business and performance, including indirectly through impacts on our customers.

Concerns over the long-term impacts of climate change have led and will continue to lead to governmental efforts around the world to mitigate those impacts. Consumers and businesses also may change their behavior as a result of these concerns. We and our customers

will need to respond to new laws and regulations as well as consumer and business preferences resulting from climate change concerns. We and our customers may face cost increases, asset value reductions and operating process changes. The impact on our customers will likely vary depending on their specific attributes, including reliance on or role in carbon intensive activities. Among the impacts to us could be a drop in demand for our products and services, particularly in oil and gas industries. In addition, we could face reductions in our creditworthiness or in the value of our assets securing loans. Our efforts to take these risks into account in making business decisions, including by increasing our business with climate-friendly companies, may not be effective in protecting us from the negative impact of new laws and regulations or changes in consumer or business behavior.

Global climate change and related emphasis on environmental, social and governance ("ESG") matters by various stakeholders could negatively affect our business.

Customer, investor and employee expectations relating to ESG have been rapidly evolving and increasing. In addition, government organizations are enhancing or advancing legal and regulatory requirements specific to ESG matters. The heightened stakeholder focus on ESG issues related to our business requires the continuous monitoring of various and evolving laws, regulations, standards and expectations and the associated reporting requirements. A failure to adequately meet stakeholder expectations may result in noncompliance, the loss of business, reputational impacts, diluted market valuation, an inability to attract customers and an inability to attract and retain top talent. In addition, our adoption of certain standards or mandated compliance to certain requirements could necessitate additional investments that could impact our profitability.

Climate changes, such as extreme weather conditions, create financial risk to our business. Global physical climate changes, including unseasonable weather conditions, could result in reduced demand or product obsolescence for certain of our customers’ products and/or price modifications for our customers’ products and the resources needed to produce them. This could in turn put pressure on our manufacturing costs and result in reduced profit margin associated with certain of our customer programs, or loss of customer programs that we may not be able to replace.

Risks Related to Human Capital Management

The loss of key personnel or inability to attract and retain additional personnel could affect our ability to successfully grow our business.

Our future success depends upon the continued service of our executive officers and other key management and technical personnel, and on our ability to continue to identify, attract, retain and motivate them. Implementing our business strategy requires specialized engineering and other talent, as our revenues are highly dependent on technological and product innovations. The market for employees in our industry is extremely competitive, and competitors for talent, particularly engineering talent, increasingly attempt to hire, and to varying degrees have been successful in hiring, our employees. If we are unable to attract and retain qualified employees, our business may be harmed.

Work stoppages or similar difficulties could significantly disrupt our operations.

As of December 31, 2023, approximately 200 of our approximately 1,200 employees are represented by international or independent labor unions under various union contracts, which, for our covered employees in the United States, expire between November 12, 2025 and May 1, 2026. It is possible that our workforce will become more unionized in the future. Although we consider our employee relations to generally be good, our existing labor agreements may not prevent a strike or work stoppage at one or more of our facilities, which may have a material adverse effect on our business. Unionization activities could also increase our costs, which could have an adverse effect on our profitability.

Additionally, a work stoppage at one of our suppliers could adversely affect our operations if an alternative source of supply were not readily available. Work stoppages by employees of our customers also could result in reduced demand for our products.

Information Technology and Cybersecurity Risks

Our dependence on information systems and the failure of such systems, could significantly disrupt our business and negatively affect our financial condition, results of operations and cash flows.

We are highly dependent on information systems that are increasingly operated by third parties and as a result we have a limited ability to ensure their continued operation. We rely on information technology systems, networks and infrastructure in managing our day-to-day operations. In the event of systems failure or interruption, including those related to force majeure, telecommunications failures, criminal acts, including hardware or software break-ins or extortion attempts, or viruses, or other cybersecurity incidents, we

will have limited ability to affect the timing and success of systems restoration and any resulting interruption in our ability to manage and operate our business could have a material adverse effect on our operating results.

Increased information technology cybersecurity threats and more sophisticated and targeted computer crime could pose a risk to our systems, networks, and products.

Increased global information technology cybersecurity threats and more sophisticated and targeted computer crime pose a risk to the security of our systems and networks and the confidentiality, availability and integrity of our data and communications. While we attempt to mitigate these risks by employing a number of measures, including employee training, comprehensive monitoring of our networks and systems, and maintenance of backup and protective systems, our systems, networks and products remain potentially vulnerable to advanced persistent threats. Depending on their nature and scope, such threats could potentially lead to the compromise of confidential information and communications, improper use of our systems and networks, manipulation and destruction of data, defective products, production downtimes and operational disruptions, which in turn could adversely affect our reputation, competitiveness and results of operations. We have cybersecurity insurance related to a breach event covering expenses for notification, credit monitoring, investigation, crisis management, public relations and legal advice. However, damage and claims arising from such incidents may not be covered or exceed the amount of any insurance available or may result in increased cybersecurity and other insurance premiums. In response to an increased reliance on our information technology systems, we have taken proactive measures to strengthen our information technology systems, including completion of a National Institute of Standards and Technology ("NIST") assessment, upgraded security patches across all servers, development of best-in-class hack protection service, implementation of recurring company-wide security training and enablement of advanced security for our major information systems. Management provides the Audit Committee with regular cybersecurity program updates including cybersecurity posture, risk management activities, and emerging risk.

Furthermore, the Company may have access to sensitive, confidential, or personal data or information that may be subject to privacy and security laws, regulations, or other contractually-imposed controls. Despite our use of reasonable and appropriate controls, material security breaches, theft, misplaced, lost or corrupted data, programming, or employee errors and/or malfeasance could lead to the compromise or improper use of such sensitive, confidential, or personal data or information, resulting in possible negative consequences, such as fines, ransom demands, penalties, loss of reputation, competitiveness or customers, or other negative consequences resulting in adverse impacts to our results of operations or financial condition.

Regulatory Compliance and International Operations Risks

Disruptions in the political, regulatory, economic and social conditions of the countries in which we conduct business could negatively impact our business, financial condition and profits.

We operate and do business in many countries in addition to the United States. For the year ended December 31, 2023, approximately 33% of our total revenue was derived from products or services ultimately delivered or provided to end users outside the United States. As part of our operating strategy, we intend to expand our international operations through internal growth and selected acquisitions. Operations outside of the United States, particularly in emerging markets, are subject to a variety of risks that are different from or are in addition to the risks we face within the United States. Among others, these risks include: (i) local, economic, political and social conditions, including potential hyperinflationary conditions and political instability in certain countries; (ii) tax-related risks, including the imposition of taxes and the lack of beneficial treaties, that result in a higher effective tax rate for us; (iii) imposition of limitations on the remittance of dividends and payments by foreign subsidiaries; (iv) difficulties in enforcing agreements and collecting receivables through certain foreign local systems; (v) domestic and foreign customs, tariffs and quotas or other trade barriers; (vi) risk of nationalization of private enterprises by foreign governments; (vii) managing and obtaining support and distribution channels for overseas operations; (viii) hiring and retaining qualified management personnel for our overseas operations; and (ix) the results of new trade agreements and changes in membership to international coalitions or unions.

We are also exposed to risks relating to U.S. policy with respect to companies doing business in foreign jurisdictions. Changes in laws or policies governing the terms of foreign trade, in particular increased trade restrictions, tariffs or taxes on import from countries where we procure or manufacture products, such as China, could have a material adverse effect on our business and results of operations. For instance, the U.S. and Chinese governments have imposed a series of significant incremental retaliatory tariffs to certain imported goods. Given the uncertainty regarding the duration of the imposed tariffs, as well as the potential for additional tariffs by the U.S., China or other countries, as well as other changes in tax policy, trade regulations or trade agreements, and the Company’s ability to implement strategies to mitigate the impact of changes in tax policy, tariffs or other trade regulations, our exposure to the risks described above could have a material adverse effect on our business and results of operations.

In addition, compliance with foreign and domestic legal and regulatory requirements, including import, export, defense regulations and foreign exchange controls and anti-corruption laws, as discussed below, such as the FCPA (as defined below), the U.K. Bribery

Act (as defined below), the European Union’s General Data Protection Regulations and similar laws of other jurisdictions, could adversely impact our ability to compete against companies in such jurisdictions. Moreover, the violation of such laws or regulations, by us or our representatives, could result in severe penalties including monetary fines, criminal proceedings and suspension of export privileges.

The occurrence of one or more of the foregoing factors could have a material adverse effect on our international operations or upon our financial condition, results of operations and cash flows.

We could be adversely affected by violations of the U.S. Foreign Corrupt Practices Act and similar anti-bribery laws worldwide.

The U.S. Foreign Corrupt Practices Act ("FCPA"), the U.K. Bribery Act of 2010 ("U.K. Bribery Act"), and similar anti-bribery laws in other jurisdictions generally prohibit companies and their intermediaries from making improper payments for the purpose of obtaining or retaining business. Our policies mandate compliance with these anti-bribery laws. We operate in many parts of the world that have experienced governmental corruption to some degree and, in certain circumstances, strict compliance with anti-bribery laws may conflict with local customs and practices. Despite our training and compliance programs, there is no assurance that our internal control policies and procedures will protect us from acts committed by our employees or agents. If we are found to be liable for FCPA, U.K. Bribery Act or other similar violations (either due to our own acts or due to the acts of others), we could be subject to civil and criminal penalties or other sanctions, which could have a material adverse impact on our business, financial condition, and profits.

Our business can be significantly affected by changes in regulatory standards.

The markets that the Company serves are characterized by competitively imposed process standards and regulatory requirements, each of which influences the demand for our products and services. Changes in legislative, regulatory or industrial requirements may render certain of our products and processes obsolete. Conversely, these changes may present new business opportunities for us. Acceptance of new products and services may also be affected by the adoption of new government regulations requiring stricter standards. Our ability to anticipate changes in regulatory standards and to respond with new and enhanced products on a timely basis will be a significant factor in our ability to grow and to remain competitive. We cannot guarantee that we will be able to achieve the technological advances that may be necessary for us to remain competitive or that certain of our products or services will not become obsolete.

Changes in current environmental legislation and enforcement could have an adverse impact on the sale of our environmental control systems and products and on our financial condition, results of operations and cash flows.

Our business is primarily driven by capital spending, clean air rules, plant upgrades by our customers to comply with laws and regulations governing the discharge of pollutants into the environment or otherwise relating to the protection of the environment or human health. These laws include, but are not limited to, United States federal statutes such as the Resource Conservation and Recovery Act of 1976, the Comprehensive Environmental Response, Compensation, and Liability Act of 1980, the Clean Water Act, the Clean Air Act, the Clean Air Interstate Rule, and the regulations implementing these statutes, as well as similar laws and regulations at state and local levels and in other countries. These United States laws and regulations may change and other countries may not adopt similar laws and regulations. Our business may be adversely impacted to the extent that environmental regulations are repealed, amended, implementation dates are delayed, or to the extent that regulatory authorities reduce enforcement.

Changes in laws or regulations or the manner of their interpretation or enforcement could adversely impact our financial performance and restrict our ability to operate our business or execute our strategies.

New laws or regulations, or changes in existing laws or regulations, or the manner of their interpretation or enforcement, could increase our cost of doing business and restrict our ability to operate our business or execute our strategies. In particular, there is continued uncertainty with respect to United States trade policies, treaties, government regulations and tariffs. Any changes the Biden administration makes to United States administrative policy could result in changes to existing trade agreements, greater restrictions on free trade generally and significant increases in tariffs on goods imported into the United States, particularly tariffs on products manufactured in Mexico and China, among other possible changes. A trade war or other governmental action related to tariffs or international trade agreements, and any resulting negative sentiments towards the United States as a result thereof, would likely have an adverse effect on our international operations or upon our business, financial condition, results of operations and cash flows.

Risks Related to Our Common Stock

The market price of our common stock may be volatile or may decline regardless of our operating performance and investors may not be able to resell shares they purchase at their purchase price.

The stock market has experienced and may in the future experience volatility that has often been unrelated to the operating performance of particular companies. The market price of our common stock has experienced, and may continue to experience, substantial volatility. During 2023, the sales price of our common stock on the NASDAQ ranged from $10.68 to $21.43 per share. We expect our common stock to continue to be subject to fluctuations. Broad market and industry factors may adversely affect the market price of our common stock, regardless of our actual operating performance. Factors that could cause fluctuation in the common stock price may include, among other things:

The realization of any of these risks and other factors beyond our control could cause the market price of our common stock to decline significantly.

We are not currently paying dividends and cannot make assurances that we will pay dividends on our common stock and our indebtedness could limit our ability to pay dividends.

The timing, declaration, amount and payment of future dividends to our stockholders fall within the discretion of our Board of Directors and will depend on many factors, including our financial condition, results of operations and capital requirements, as well as applicable legal or regulatory constraints, industry practice and other business considerations that our Board of Directors considers relevant. We have not paid a cash dividend on our common stock in recent years and currently intend to retain future earnings, if any, to finance the operations, growth and development of our business into the foreseeable future.

Our ability to issue preferred stock could adversely affect the rights of holders of our common stock.

Our certificate of incorporation authorizes us to issue up to 10,000 shares of preferred stock in one or more series on terms that may be determined at the time of issuance by our Board of Directors. Accordingly, we may issue shares of any series of preferred stock that would rank senior to our common stock as to voting or dividend rights or rights upon our liquidation, dissolution or winding up.

Certain provisions in our charter documents have anti-takeover effects.

Certain provisions of our certificate of incorporation and bylaws may have the effect of delaying, deferring or preventing a change in control of us. Such provisions, including those limiting who may call special stockholders’ meetings, together with the possible issuance of our preferred stock without stockholder approval, may make it more difficult for other persons, without the approval of our Board of Directors, to make a tender offer or otherwise acquire substantial amounts of our common stock or to launch other takeover attempts that a stockholder might consider to be in such stockholder’s best interest.

Risks Related to Internal Control over Financial Reporting

We have identified material weaknesses in our internal control over financial reporting. If we are unable to develop and maintain adequate internal controls, we may not be able to accurately report our financial results in a timely manner, which may adversely affect investor confidence in us and materially and adversely affect our business.

Under Section 404 of the Sarbanes-Oxley Act of 2002, we are required to include in each of our Annual Reports on Form 10-K a report containing our management’s assessment of the effectiveness of our internal control over financial reporting and an attestation report of our independent auditor. These laws, rules and regulations continue to evolve and could become increasingly stringent in the future. We have undertaken actions to enhance our ability to comply with the requirements of the Sarbanes-Oxley Act of 2002, including, but not limited to, the engagement of consultants, the documentation of existing controls and the implementation of new controls or modification of existing controls as deemed appropriate.

We continue to devote substantial time and resources to the documentation and testing of our controls, and to plan for and the implementation of remedial efforts in those instances where remediation is indicated.

As disclosed in Item 9A. “Controls and Procedures” in this Annual Report on Form 10-K, we have material weaknesses in our control environment with regard to management’s review of revenue recognition for contracts and balance sheet reconciliations. These material weaknesses could result in a misstatement of account balances or disclosures that would result in a material misstatement to the annual or interim financial statements that would not be prevented or detected.

To address these material weaknesses, we have developed a remediation plan that includes reinforcing the importance of adherence to Company policies regarding control performance and related documentation with control owners, strengthening existing training programs for control owners, and developing monitoring activities to validate the performance of controls by control owners. As of December 31, 2023, these remediation efforts are ongoing.

The actions that we are taking are subject to ongoing senior management review, as well as Audit Committee oversight. We will not be able to conclude whether the steps we are taking will fully remediate the material weaknesses in our internal control over financial reporting until we have completed our remediation efforts and subsequent evaluation of their effectiveness. Until these material weaknesses are remediated, we plan to continue to perform additional analyses and other procedures to ensure that our consolidated financial statements are prepared in accordance with GAAP.

If we continue to have material weaknesses in our internal controls, or, if we fail to develop and maintain adequate internal controls in the future, including remediating any material weaknesses or deficiencies in our internal controls, we could be subject to regulatory actions, civil or criminal penalties or stockholder litigation. In addition, failure to maintain adequate internal controls could result in financial statements that do not accurately reflect our financial condition, results of operations and cash flows. We believe that the out-of-pocket costs, the diversion of management’s attention from running our day-to-day operations and operational changes caused by the need to comply with the requirements of Section 404 of the Sarbanes-Oxley Act of 2002 will continue to be significant.

There are inherent limitations in all internal control systems over financial reporting, and misstatements due to error or fraud may occur and not be detected.

While we continue to take action to ensure compliance with the internal control, disclosure control and other requirements of the Sarbanes-Oxley Act of 2002 and the rules and regulations promulgated thereunder by the SEC, there are inherent limitations in our ability to control all circumstances. Our management, including our Chief Executive Officer and Chief Financial and Strategy Officer, do not expect that our internal controls and disclosure controls can prevent all errors and all frauds. A control system, no matter how well conceived and operated, can provide only reasonable assurance that the objectives of the control system are met. In addition, the design of a control system must reflect the fact that there are resource constraints and the benefit of controls must be evaluated in relation to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty and that breakdowns can occur because of simple error or mistake. Further, controls can be circumvented by individual acts of some persons, by collusion of two or more persons or by management override of the controls. The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Over time, a control may be inadequate because of changes in conditions or the degree of compliance with the policies or procedures may deteriorate. Because of inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.

If we are not able to establish and maintain effective internal control over financial reporting, including any failure to implement required new or improved controls, or if we experience difficulties in their implementation, our business, financial condition and

operating results could be harmed. We can give no assurances that any additional material weaknesses will not arise in the future due to our failure to implement and maintain adequate internal control over financial reporting.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Management’s discussion and analysis (“MD&A”) should be read in conjunction with the consolidated financial statements and accompanying notes included in Item 8 of this Annual Report on Form 10-K, which include additional information about our accounting policies, practices and the transactions underlying our financial results. The preparation of our consolidated financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the reported amounts in our consolidated financial statements and the accompanying notes including various claims and contingencies related to lawsuits, taxes, environmental and other matters arising during the normal course of business. We apply our best judgment, our knowledge of existing facts and circumstances and actions that we may undertake in the future in determining the estimates that affect our consolidated financial statements. We evaluate our estimates on an ongoing basis using our historical experience, as well as other factors we believe appropriate under the circumstances, such as current economic conditions, and adjust or revise our estimates as circumstances change. As future events and their effects cannot be determined with precision, actual results may differ from these estimates.

Overview

Business Overview

CECO is a leading environmentally focused, diversified industrial company, serving the broad landscape of industrial air, industrial water and energy transition markets globally by providing innovative technology and application expertise. We help companies grow their business with safe, clean, and more efficient solutions that help protect people, the environment and industrial equipment. Our solutions improve air and water quality, optimize emissions management, and increase the energy and process efficiency for highly engineered applications in power generation, midstream and downstream hydrocarbon processing and transport, chemical processing, electric vehicle production, polysilicon fabrication, semiconductor and electronics production, battery production and recycling, specialty metals, aluminum and steel production, beverage can manufacturing, and industrial and produced water and wastewater treatment, and a wide range of other industrial end markets.

Industry Trends and Corporate Strategy

We are a global corporation with worldwide operations. As a global business, our operations are affected by worldwide, regional and industry-specific economic factors, wherever we operate or do business. Our geographic and industry diversity, and the breadth of our product and services portfolio, have helped mitigate the impact of any one industry or the economy of any single country on our consolidated operating results.

We believe growth for our products and services is driven by the increase in demand for air quality and water treatment solutions, the energy transition, a shift towards cleaner sources of fuel such as natural gas, hydrogen, nuclear, and renewable sources, and increased awareness of our customers about corporate social responsibility and interest to procure equipment and solutions that protects employees, the environment and their industrial equipment.

With a shift to cleaner, more environmentally responsible power generation, power providers and industrial power consumers are building new facilities that use cleaner fuels. In developed markets, natural gas is the largest source of electricity generation. We supply product offerings throughout the entire natural gas value chain and believe expansion will drive growth within our Engineered Systems segment for our gas separation & filtration, pressure products, acoustical equipment , water treatment solutions and DeNOx SCR systems for natural-gas-fired power plants. Increases in global natural gas, installed miles of new pipeline, including future CO2 and hydrogen pipelines, and liquified natural gas ("LNG") demand and supply all stand to drive the need for our products.

We also believe there is a growing demand to control and reduce air and water emissions from industrial facilities for which our pollution control equipment will serve. In 2021, the US Congress passed the Infrastructure Investment and Jobs Act with $550 billion of new federal spending aimed at rebuilding roads and bridges, climate resilience, and other environmental initiatives. Similar investments are being made in many other countries in which we do business. As industrial capital expenditures grow, corporations are seeking to do so with a smaller environmental impact. These regulatory and economic tailwinds coupled with shareholder pressure on companies to improve their sustainability and reduce their global carbon footprint serve as catalysts for a growing set of opportunities for our portfolio of equipment and solutions.

We continue to focus on increasing revenues and profitability in developing markets, where environmental awareness and associated regulatory standards are increasing, while continuing to strengthen and expand our product offerings and channels in our domestic market of the United States. Our enterprise strategy consists of a combined operational strategy and capital allocation strategy.

Our operational strategy is implemented through our technology and application-based platforms aligned around target customers and end markets where our solutions are particularly valuable. Core elements of our operational strategy are commercial and operational excellence, margin expansion, recurring revenue growth, cash flow generation, product management, and project management execution.

Our capital allocation strategy supports the growth and value creation generated by our operational strategy. We will focus our capital deployment on building out our leading industrial air solutions portfolio, advancing our emerging industrial water treatment position, and supporting our customers as they make the transition to cleaner more sustainable forms of energy, while also shifting our portfolio mix towards businesses with more recurring revenue and more predictable cash flows, strong secular growth trends and less cyclicality.

Market Pressures

The senior management team monitors and manages the Company’s ability to operate effectively as the result of market pressures. In particular, we are currently experiencing shortages of raw materials and inflationary pressures for certain materials and labor. We have secured raw materials from existing and alternate suppliers and have taken other mitigating actions to mitigate supply disruptions; however, we cannot guarantee that we can continue to do so in the future. In this event, our business, results and financial condition could be adversely affected.

Operations Overview

We operate our segments and the underlying platforms serving their respective niche end markets. Our platforms are structured to win in their target markets with a core focus on understanding customer needs and providing best-in-class solutions. Our business model provides scalable efficiencies enabling us to serve our customers with a variety of products that we typically classify into three categories: make-to-order, configure-to-order, and engineer-to-order. For our project-based platforms, we leverage third-party subcontract fabrication partners in a global network to execute for our customers world-wide. Our platforms are focused on sales, application engineering, product management, project management, and supply chain execution for our customers.

Our operations management team has distinct industry expertise coupled with strong leadership skills resulting in a customer-first mindset across the business. Our operations management team works closely with our Chief Executive Officer on global fulfillment strategies, operational excellence, resource allocation, and employee development.

Within our segments we have monthly business reviews to ensure we are serving customers, achieving our operating plan, and executing on strategic growth initiatives. These reviews include, but are not limited to pipeline reviews, quotation reviews, project management reviews, financial performance, manufacturing scorecards, safety, and customer feedback. In these reviews we focus on metrics such as quality, customer satisfaction, on-time-delivery, lead-times, price, inflation, project margins, backlog, and above all, safety.

In support of the segments, centralized teams provide back-office functions for scale, efficiency, and compliance. These key functions include: accounting, treasury, tax, payroll, human resources and total rewards management, legal, information technology, marketing, and internal control over financial reporting. We have excellent collaboration between our platforms and our centralized service teams ensuring optimal efficiency and alignment on growth and improvement initiatives.

Our reportable segments are:

Our contracts are obtained either through competitive bidding or as a result of negotiations with our customers. Contract terms offered by us are generally dependent on the complexity and risk of the project as well as the resources that will be required to complete the project. Our focus is on increasing our operating margins as well as our gross margin percentage, which translates into stronger operating results.

Our cost of sales is principally driven by a number of factors, including material and subcontract prices and labor cost and availability. Changes in these factors may have a material impact on our overall gross profit margins.

We break down costs of sales into five categories, as follows:

In general, subcontracts are the highest percentage of costs and also the most flexible followed by labor, material, and equipment. Due to the project nature and global orientation of several of our platforms, leveraging subcontract fabrication partners close to our customers increases our ability to meet customer delivery expectations at market competitive pricing. In periods where orders are infrequent, we do not have to maintain the fixed cost of a manufacturing plant. Across our various product lines, the relative relationships of these cost categories change and cause variations in gross margin percentage. Material and labor costs can increase quickly, which also reduces gross margin percentage. As material cost inflation occurs, the Company seeks to pass this cost onto our customers as price increases.

Selling and administrative expense principally includes sales and engineering payroll and related fringes, advertising and marketing expenditures as well as all corporate and administrative functions and other costs that support our operations. The majority of these expenses are fixed. An advantage of our operating model is that as revenue grows, we have significant operating leverage on our fixed selling and administrative cost structure.

Note Regarding Use of Non-GAAP Financial Measures

The Company’s consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). These GAAP financial statements include certain charges the Company believes are not indicative of its core ongoing operational performance.

As a result, the Company provides financial information in this MD&A that was not prepared in accordance with GAAP and should not be considered as an alternative to the information prepared in accordance with GAAP. The Company provides this supplemental non-GAAP financial information, because the Company’s management utilizes it to evaluate its ongoing financial performance and the Company believes it provides greater transparency to investors as supplemental information to its GAAP results.

The Company has provided the non-GAAP financial measures including non-GAAP operating income, non-GAAP operating margin, and non-GAAP net income as a result of the adjustment for items that the Company believes are not indicative of its ongoing operations. These items include charges associated with the Company’s acquisitions, and the items described below in “Consolidated Results.” The Company believes that evaluation of its financial performance compared with prior and future periods can be enhanced by a presentation of results that exclude the impact of these items. The Company has incurred substantial expense and generated substantial income associated with acquisitions. While the Company cannot predict the exact timing or amounts of such charges, it does expect to treat these charges as special items in its future presentation of non-GAAP results.

Results of Operations

Consolidated Results

Our consolidated statements of income for the years ended December 31, 2023, 2022 and 2021 are as follows:

Non-GAAP Measures

To compare operating performance between the years ended December 31, 2023, 2022 and 2021 the Company has adjusted GAAP operating income to exclude (1) amortization of intangible assets, and earnout expenses, (2) restructuring expenses primarily relating to severance, facility exits, and associated legal expenses, (3) acquisition and integration expenses, which include legal, accounting, and other expenses, (4) executive transition expenses, including severance for the Company's former executives, fees and expenses incurred in the search, for and hiring, of new executives and (5) intangible asset impairment. See “Note Regarding Use of Non-GAAP Financial Measures” above. The following tables present the reconciliation of GAAP operating income and GAAP operating margin to non-GAAP operating income and non-GAAP operating margin, and GAAP net income to non-GAAP net income.

Comparison of the years ended December 31, 2023 and 2022

Consolidated net sales in 2023 were $544.8 million compared with $422.6 million in 2022, an increase of $122.2 million or 28.9%. The increase was led by increases of $88.2 million in our separation, filtration and industrial water businesses and $21.2 million in our thermal acoustics technologies. Approximately 58.2%, or $71.1 million, of the increase in net sales is attributable to organic revenue growth, defined as revenue recorded subsequent to the twelve-month period post-acquisition date, while $51.1 million is attributable to acquisitions that have occurred during the preceding twelve-month period.

Gross profit increased by $42.8 million, or 33.4%, to $171.0 million in 2023 compared with $128.2 million in 2022. The increase in gross profit was primarily attributable to the increase in sales volume as described above. Gross profit as a percentage of sales increased to 31.4% in 2023 compared with 30.3% in 2022 due to higher project margin mix executed during the year and price increases. We continue to experience shortages of raw materials and inflationary pressures for certain materials and labor. We have secured additional raw materials from existing and alternate suppliers and have taken other mitigating actions to mitigate supply disruptions, such as implementing price increases and applying material surcharges, we cannot guarantee that we can continue to do so in the future. In this event, our business, results and financial condition could be adversely affected.

Orders booked were $582.8 million in 2023 compared with $526.6 million in 2022. This $56.2 million increase is primarily attributable to recent acquisitions.

Selling and administrative expenses were $122.9 million in 2023 compared with $93.4 million in 2022. The increase is primarily attributed to acquisitions during 2023, as well as increased investment to support our revenue growth and increased backlog. Selling and administrative expenses as a percentage of sales were flat, with 22.6% in 2023 compared with 22.1% in 2022.

Amortization and earnout expenses were $8.2 million in 2023 and $6.8 million in 2022. The increase in expense is attributable to an increase of $0.9 million in definite lived asset amortization due to recent acquisitions and $0.5 million in earnout expense. See Note 7 to the Consolidated Financial Statements for further discussion on earnout expenses.

Acquisitions and integration expenses related to various merger and acquisition diligence activities, which include legal, accounting and banking expenses, were $2.5 million in 2023, as compared with $4.5 million in 2022. The decrease is due to the timing of acquisition activity. See Note 14 to the Consolidated Financial Statements for further discussion on recent acquisitions.

Executive transition expenses were $1.5 million in 2023 compared to $1.2 million in 2022. These expenses related to fees and other expenses incurred in the search for and hiring of new executives, specifically the Chief Administrative and Legal Officer and Chief Finance and Strategy Officer for 2022 and Chief Operating Officer and Chief Accounting Officer for 2023.

Restructuring expenses were $1.4 million in 2023 compared to $0.1 million in 2022. These expenses related to severance, facility exits, and associated legal expenses, primarily as it relates to the exit of certain operations in China at the end of 2023.

Operating income for 2023 was $34.6 million, an increase of $12.4 million from $22.2 million in 2022. Operating income as a percentage of sales for 2023 was 6.4% compared with 5.3% for 2022. The increase in operating income is primarily attributable to increases in net organic sales and gaining operating leverage.

Non-GAAP operating income was $48.1 million in 2023 and $34.8 million in 2022. The increase in non-GAAP operating income is primarily attributable to the increase in net organic sales and improved operating leverage. Non-GAAP operating income as a percentage of sales for 2023 was 8.8% compared with 8.2% for 2022.

Other income for 2023 was $0.4 million compared to $6.9 million in 2022. The decrease in other income was primarily attributable to net foreign currency transaction losses in the current year based on changes in exchange rates at our foreign subsidiaries.

Interest expense increased to $13.4 million in 2023 from $5.4 million in 2022. The increase in interest expense is primarily due to higher interest rates and increased debt balances to fund acquisitions.

Income tax expense was $7.0 million and $5.4 million in 2023 and 2022, respectively. The effective tax rate for 2023 was 32.6% compared with 22.9% in 2022. Income tax expense and the effective tax rate for 2023 were affected by changes in valuation allowances, and the net impact of global intangible low-taxed income ("GILTI") and foreign-derived intangible income ("FDII"), as well as certain permanent differences including state income taxes, non-deductible incentive stock-based compensation, and differences in tax rates among the jurisdictions in which we operate.

The results of the segments are reviewed through the “Income from operations” line on the Consolidated Statements of Income. The amounts presented in the Net Sales table below and in the following comments regarding our net sales at the reportable business segment level exclude both intra-segment and inter-segment net sales. The Income from Operations table and corresponding comments regarding operating income at the reportable segment level include both intra-segment and inter-segment operating income.

Comparison of the years ended December 31, 2023 and 2022

Engineered Systems segment

Our Engineered Systems segment net sales increased $116.9 million to $380.1 million in 2023 compared with $263.2 million in 2022, an increase of 44.4%. The increase is broad-based, led by increases of $88.2 million in our separation, filtration and industrial water businesses and $21.2 million in our thermal acoustics technologies. Approximately 56.6%, or $66.2 million, of the increase in net sales is attributable to organic revenue growth, while $50.7 million is attributable to acquisitions that have occurred during the preceding twelve-month period.

Operating income for the Engineered Systems segment increased $23.6 million to $59.8 million for 2023 compared with $36.2 million in 2022, an increase of 65.2%. The increase in operating income in primarily attributable to higher gross profit related to increased sales.

Industrial Process Solutions segment

Our Industrial Process Solutions segment net sales increased $5.3 million to $164.7 million in 2023 compared with $159.4 million in 2022, an increase of 3.3%. The increase is primarily attributable to an increase of $4.7 million in our duct fabrication and installation businesses. Approximately 62.3%, or $3.3 million, of the increase in net sales is attributable to organic revenue growth, while $2.0 million is attributable to acquisitions that have occurred during the preceding twelve-month period.

Operating income was $21.6 million in 2023 compared with $22.7 million in 2022. The decrease is primarily attributable to $1.0 million of restructuring expenses incurred in 2023.

Corporate and Other segment

Operating expense for the Corporate and Other segment increased $10.2 million to $46.9 million for 2023 compared with $36.7 million for 2022. The increase is primarily attributable to inflationary increases in wages and services, as well as increased headcount in order to support our revenue growth.

Comparison of the years ended December 31, 2022 and 2021

See the Management Discussion and Analysis section of our Annual Report on Form 10-K for the year ended December 31, 2022 for a discussion of business segment results of operations for the year ended December 31, 2022 compared to the year ended December 31, 2021.

Liquidity and Capital Resources

When we undertake large jobs, our working capital objective is to make these projects self-funding. We work to achieve this by obtaining initial down payments, progress billing contracts, when possible, utilizing extended payment terms from material suppliers, and paying sub-contractors after payment from our customers, which is an industry practice. Our investment in net working capital is funded by cash flow from operations and by our revolving line of credit.
