We are led by an experienced management team that has contributed to our growth by establishing deep and long-standing relationships with key customers and has worked to expand the customer base both organically and through strategic acquisitions.

Table of Contents

We maintain an established base of long-standing customers comprised of leading, blue-chip OEM manufacturers across the United States. Our broad capabilities offering and track record of producing the highest quality solutions have allowed us to establish, and subsequently deepen, relationships with additional products and platforms over time. For example, our more than 40-year relationship with Deere & Company (John Deere) began with a small order of simple stamped parts for a farm tractor in its agricultural segment that expanded over time and represented 2025 sales in excess of $54 million across five market segments, representing over 65 model platforms. We have also been successful in winning customers and rapidly expanding relationships with high-growth customers by utilizing our complete product lifecycle management offering. For instance, we began our relationship with a powersports company less than ten years ago, starting with our expertise in performance structure suspension components, and we have been able to expand our relationships into tubes, fabrications and finished goods assemblies. Through this expansion, with product shipping from multiple facilities, we have been able to deepen our relationship and expand our market position through each of their new product updates, solidifying us as a strategic partner.

We serve our customers through 27 strategically located U.S. facilities, of which 25 are in operation, across nine states, with approximately three and a half million square feet of manufacturing capacity.

In addition, the ongoing investment in flexible, re-deployable automation allows us to expand output while reducing cost and improving quality, productivity and consistency for margin enhancement and market leading competitiveness.

Our historical success is a function of our engineering expertise, extensive manufacturing capabilities, limited commodity exposure, investment in automation and relationships with the contractual ability to pass through variability in commodity prices. We believe we are poised to grow through economic cycles due to our:

●

market positioning and reputation;

●

product breadth;

●

flexible and re-deployable capital investment in automation and process capabilities; and

●

our geographic, end market and product diversification.

Our diversified profile today best positions us for stability and leading market performance through all phases of an economic cycle.

Our Industry

We compete in the highly fragmented market of contract manufacturers, the majority of which are small local players that are limited in scale, capabilities and technology. Many of these local manufacturers have single or limited production capabilities and provide niche components in specific geographic markets. Accordingly, there are a limited number of competitors in the value-added manufacturing market in which we operate with the capacity and expertise to deliver the complete product lifecycle of solutions we offer. For example, our diverse manufacturing capabilities across product lines have contributed to us being selected the Largest Fabricator by The Fabricator magazine’s “FAB 40” listing in the desirable U.S. markets for the past 15 years in a row (2011 – 2025). While we compete with certain manufacturers across selected product lines, we believe that no single manufacturer directly competes with us across our full offering and end market applications.

Our end market diversification coupled with our extensive product breadth allows us to maintain financial stability as individual end markets fluctuate. The primary end markets we serve include heavy- and medium-duty commercial vehicles, construction & access equipment, powersports, data center & critical power, agriculture and military, among others. As markets strengthen or weaken, our output is redirected and realigned to support ongoing change.

We have also experienced, and benefitted from, OEM trends seeking to improve their strategy execution and simplify their business through outsourcing and reshoring. Based on our history, OEMs pursue a strategy that focuses on core component market differentiation, such as structural frames and complete powertrain assemblies, and prefer to outsource the remaining product

Table of Contents

components to third parties rather than manufacturing them in-house. This is done in order to maintain their strategic focus, drive cost savings and reduce their own investment in manufacturing, thereby allowing them to focus on the most important aspects of their value creation process, namely product design and development, final product assembly and testing, branding, sales, marketing and distribution. While each specific OEM differs in its strategy, we see these trends continuing as customers deal with workforce constraints and look for optimum return on investments while improving cash flow. Moreover, our OEM customers focus on the production of the core components of their products, which leads them to rely on outsourced providers like us for the remaining components of their finished product needs. OEMs are also continuing to bring production back to the US and simplifying their supply chain processes. We believe we will benefit from this continued shift in our customers’ focus and ongoing desire for OEMs to improve efficiencies, reduce costs and simplify supply chains. Our established and embedded relationships, breadth of capabilities and scalability will allow us to streamline the supply chain process for our customers by acting as a single point of contact in the supply chain. In addition, we believe OEMs are increasingly favoring platforms supported by larger, more sophisticated and financially stable suppliers with the ability to serve large national and international operations all while maintaining a local touch. Our extensive manufacturing footprint, competitive cost structure and integrated design, engineering, production planning and quality program management capabilities position us favorably to take advantage of these opportunities and trends.

In our experience, our diversification has muted the impact of downturns on our business that have affected us in the past. For example as our heavy- and medium-duty commercial vehicles, construction & access equipment, powersports, data center & critical power and agriculture customers’ revenues fluctuated from 2013 to 2017, with median peak-to-trough sales decline of 23%, our peak-to-trough sales declines were less than that of those respective markets at only 10%. We were able to accomplish this by reallocating our resources to serve our heavy- and medium-duty commercial vehicles and powersports customers, leading to strong double-digit growth in those end markets.

●

Heavy- and Medium-Duty Commercial Vehicles: Heavy-duty commercial vehicles include class 8 heavy trucks such as standard semi-trucks. Medium-duty commercial vehicles include classes 3-7 trucks such as box trucks;

●

Construction & Access Equipment: Primary applications include wheel loaders, crawlers, skid steer loaders, excavators, motor graders, aerial lifts, boom lifts and other construction equipment;

Our Customers

We are a critical and deeply embedded supply partner with strong strategic alignment and relationships with our customers. We have developed long-standing business relationships with our OEM customers, many of which span decades. Further, we are diversified by customers and end markets with net sales attributed to our top 20 customers accounting for $421 million of 2025 net sales, and no single end market accounting for more than 32% of net sales. For the year ended December 31, 2025, PACCAR Inc. and John Deere accounted for 13.6% and 10.0% of net sales, respectively. We have not historically experienced customer attrition given high customer switching costs resulting from our embedded relationships driven by our broad capabilities and scale.

Raw Materials and Manufactured Components

Our primary purchased commodities are steel and aluminum. We maintain a broad and diverse base of over 900 direct material suppliers. Our established relationships provide efficient and flexible access to resources and redundancy to ensure support of our customers. We have no history of significant supply issues or outages. In 2025, no single supplier represented more than 9% of our total raw material purchases and over 90% of the raw materials we purchased were sourced from suppliers in the United States. Our suppliers are strategically located to maximize efficiencies and minimize shipping costs. We maintain a multitude of alternative suppliers to which we could transfer orders to, if needed. As we continue to grow, however, we intend to leverage our size and scale to rationalize our supply base to further reduce material costs. We have structured our customer contracts to pass through commodity price changes, which has allowed us to limit any potential impact of raw material price volatility and tariffs to our margins.

Sales and Marketing

We have a strong sales team comprised of approximately 50 experienced professionals responsible for managing and expanding client relationships and proactively pursuing new opportunities. Sales personnel are aligned by market segment and customer, including heavy- and medium-duty commercial vehicles, construction & access equipment, powersports, data center & critical power, agriculture, military and other end markets, and employ a highly technical and collaborative sales process with deep knowledge of our customers and capabilities. Sales personnel have assigned support teams comprised of inside sales and account management, commercial operations, estimating and application engineering and marketing personnel. We are consistently involved in the request for proposal processes, where our sales teams with deep process expertise collaborate with customers on optimal designs for manufacturability and manufacturing efficiency. The upfront collaboration drives formalization of product specifications, program lifecycle planning, cost estimates and risk mitigation. The sales process typically takes 3 to 18 months and ultimately ends in the implementation of product lifecycle timelines and purchase orders under long-term customer arrangements. The sales team utilizes systems infrastructure that effectively track and manage backlogs, quotes and bookings information, strategic projects and call reports, all of which are reviewed at weekly sales team meetings.

Information Systems

We utilize standardized information technology systems across all areas of quoting and estimating, enterprise resource planning, materials resource planning, capacity planning and accounting for enhanced procurement of work, project execution and financial controls. We provide information technology oversight and support from our corporate headquarters in Milwaukee, WI. The operational information systems we employ throughout our company are industry specific applications that in some cases have been internally or vendor modified and improved to fit our operations. Our enterprise resource planning software is integrated with our operational information systems wherever possible to deliver relevant, real-time operational data to designated personnel. Accounting and operations personnel of acquired companies are trained not only by our information technology support staff, but by long-tenured employees in our organization with extensive experience using our systems. We believe our information systems provide our people with the tools to execute their individual job function and achieve our strategic initiatives.

Our Competition

We participate in a highly fragmented market with competitors in each of the end markets we serve ranging in size from small companies focused on a single capability or end market, to large multi-disciplinary companies. While there can be instances of intense competition in specific end markets, we believe that we have been able to effectively compete, and maintain competitive advantages on the basis of our:

●

scale and product offering with the ability to cross-sell and provide our customers with a one-source solution;

●

broad manufacturing capability and flexibility to fulfill requests that require complex solutions;

●

customer service with our highly skilled and knowledgeable workforce able to provide consultative advice; and

●

regionalized geographic focus provides a defensible position from both foreign and domestic competitors as our customers continue to take a regionalized approach to production, which provides a shorter supply chain with greater flexibility.

Item 1A. Risk Factors.

Investing in our common stock involves risk. You should carefully consider the risks and uncertainties described below, together with all of the other information in this Annual Report on Form 10-K, including “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and our consolidated financial statements and related notes, before making a decision to invest in our common stock. The risks and uncertainties described below may not be the only ones we face. If any of the risks actually occur, our business, financial condition, operating results and prospects could be materially and adversely affected. In that event, the market price of our common stock could decline, and you could lose part or all of your investment.

Risks Related to Our Business

Macroeconomic conditions could have a material adverse impact on our business, financial condition, cash flows and results of operations.

Macroeconomic conditions, including inflation, elevated interest rates, labor availability, material cost pressures, trade policy uncertainty, and inconsistent customer demand, have had, and may continue to have, a negative impact on our business, financial condition, cash flows and results of operations. In 2025 and early 2026, actions taken by the U.S. government, including the implementation and expansion of tariffs on a broad range of imported goods and materials, contributed to increased input costs, supply chain disruption, pricing volatility, and heightened economic uncertainty. These changes in trade policy, along with the recent U.S. Supreme Court decision to strike down certain tariffs imposed under the International Emergency Economic Powers Act have created uncertainty as to the scale and short and long-term effects these tariffs may have on our business. These actions, along with retaliatory measures by U.S. trading partners, have placed additional pressure on manufacturers by increasing the cost of raw materials, components, and energy and by contributing to broader inflationary trends. For instance, we were negatively impacted in 2025 by customer channel inventory destocking and macroeconomic uncertainty. In addition, in 2025, continued inflationary pressures on wages, benefits, materials, manufacturing supplies, and logistics costs negatively impacted our results of operations and cash flows.

We expect material cost inflation and inflationary pressures on wages and benefits to continue in 2026, and we may not be able to fully mitigate the impact of these inflationary cost pressures through price increases or operational efficiencies. Further changes in trade policy, including the expansion, modification, or continuation of tariffs, as well as any related retaliatory actions, could further increase our costs or disrupt supply chains. Continuing or worsening inflation, labor challenges, trade policy uncertainty and elevated interest rates may have a material adverse impact on our business, financial condition, cash flows and/or results of operations.

Although we do not have any operations outside the United States, geopolitical events including the ongoing conflicts between Russia and Ukraine, tensions in the Middle East and U.S. trade policy actions, have increased uncertainty in the global economy and have led to significant volatility in raw material costs, component costs, commodity prices, and energy costs, exacerbating inflationary pressures.

We are affected by developments in the industries in which our customers operate.

We derive our net sales from customers in the following industry sectors: heavy- and medium-duty commercial vehicles, construction & access equipment, powersports, data center & critical power, agriculture, military and other end markets. Factors affecting any of these industries in general, or any of our customers in particular, could adversely affect us because our net sales growth largely depends on the continued growth of our customers’ businesses in their respective industries. These factors include:

●

seasonality of demand for our customers’ products, and/or customer destocking activities, which may cause our manufacturing capacity to be underutilized for periods of time;

Table of Contents

●

our customers’ failure to successfully market their products, to gain or retain widespread commercial acceptance of their products or to compete effectively in their industries;

●

loss of market share for our customers’ products, which may lead our customers to reduce or discontinue purchasing our processes and solutions or to reduce prices, thereby exerting pricing pressure on us;

●

economic conditions in the markets in which our customers operate, in particular, the United States, including the growth potential and relative stability of the data center & critical power end market, inflationary pressures and other negative impacts on economic conditions, as well as recessionary periods such as a global economic downturn;

●

our customers’ decision to insource the production of components that has traditionally been outsourced to us; and

●

product design changes or manufacturing process changes that may reduce or eliminate demand for the components we supply.

We expect that future sales will continue to depend on the success of our customers. If economic conditions and demand for our customers’ products deteriorate, we may experience a material adverse effect on our business, operating results and financial condition.

Most of our customers do not commit to long-term production schedules, which makes it difficult for us to schedule production accurately and achieve maximum efficiency of our manufacturing capacity.

Most of our customers do not commit to long-term contracts or firm production schedules, and we continue to experience reduced lead-times in customer orders. Additionally, customers may change production quantities or delay production with little lead-time or advance notice. Therefore, we rely on and plan our production and inventory levels based on our customers’ advance orders, commitments and/or forecasts as well as our internal assessments and forecasts of customer demand. The volume and timing of sales to our customers may vary due to, among others:

●

variation in demand for or discontinuation of our customers’ products;

●

our customers’ attempts to manage their inventory;

●

design changes;

●

changes in our customers’ manufacturing strategies;

●

disruptive events in the markets in which our customers operate, including natural disasters and epidemics;

●

acquisitions of or consolidation among customers.

The variations in volume and timing of sales make it difficult to schedule production and optimize utilization of manufacturing capacity. This uncertainty may require us to increase staffing and incur other expenses in order to meet an unexpected increase in customer demand, potentially placing a significant burden on our resources. Additionally, an inability to respond to such increases in a timely manner may cause customer dissatisfaction, which may negatively affect our customer relationships.

Further, in order to secure sufficient production scale, we may make capital investments in advance of anticipated customer demand (including, in some instances, new customer demand). Such investments may lead to low utilization levels if demand forecasts change and we are unable to utilize the additional capacity. Because fixed costs make up a large proportion of our total production costs, a reduction in customer demand can have a significant adverse impact on our gross profits and operating results. Additionally, we order materials and components based on customer forecasts and orders and suppliers may require us to purchase materials and components in minimum quantities that exceed customer requirements, which may have an adverse impact on our gross profits and operating results. In the past, anticipated orders from some of our customers and anticipated new customers have failed to materialize and/or delivery schedules have been deferred as a result of changes in our customers’ business needs.

Table of Contents

We may be unable to realize net sales represented by our awarded business, which could materially and adversely impact our business, financial condition, results of operations and cash flows.

The realization of future net sales from awarded business is inherently subject to a number of important risks and uncertainties, including a lack of long-term commitments and production schedules with customers and anticipated new customers. Accordingly, we cannot assure you that we will realize any or all of the future net sales represented by our awarded business. Any failure to realize these net sales could have a material adverse effect on our business, financial condition, results of operations and cash flows.

In addition to not having a commitment from our customers and anticipated new customers regarding the minimum number of components they must purchase from us if we obtain awarded business, typically the terms and conditions of the agreements with our customers provide that they have the contractual right to unilaterally terminate our contracts with them with no notice or limited notice. In many cases, we must commit substantial resources in preparation for production under awarded customer business well in advance of the customer’s production start date. If such contracts are terminated by our customers, our ability to obtain compensation from our customers for such termination is generally limited to the direct out-of-pocket costs that we incurred for raw materials and work-in-progress. Although we have been successful in recovering these costs under appropriate circumstances in the past, we cannot assure you that our results of operations will not be materially adversely impacted in the future if we are unable to recover these types of pre-production costs related to our customers’ cancellation of awarded business.

Failure to compete successfully in our markets could materially adversely affect our business, financial condition, results of operations or prospects.

We offer our processes and solutions in highly competitive markets. The competitors in these markets may, among other things:

●

respond more quickly to new or emerging technologies;

●

have greater name recognition, critical mass or geographic market presence;

●

be better positioned to take advantage of acquisition opportunities;

●

adapt more quickly to changes in customer requirements;

●

devote greater resources to the development, promotion and sale of their processes and solutions;

●

be better positioned to compete on price due to any combination of low-cost labor, raw materials, components, facilities or other operating items, or willingness to make sales at lower margins than us;

●

consolidate with other competitors in the industry which may create increased pricing and competitive pressures on our business; and

●

be better able to utilize excess capacity which may reduce the cost of their processes and solutions.

Competitors with lower cost structures may have a competitive advantage over us. We also expect our competitors to continue to improve the performance of their current processes and solutions, to reduce the prices of their existing processes and solutions and to introduce new processes or solutions that may offer greater performance and improved pricing. Additionally, we may face competition from new entrants to the industry in which we operate. Any of these developments could cause a decline in sales and average selling prices, loss of market share or profit margin compression. Maintaining and improving our competitive position will require successful management of these factors, including continued investment by us in research and development, engineering, marketing and customer service and support. Our future growth rate depends upon our agility to compete successfully, which is impacted by a number of factors, including, but not limited to, our ability to (i) identify emerging technological trends in our target end markets, (ii) develop and maintain a wide range of competitive and appropriately priced processes and solutions and defend our market share against an ever-expanding number of competitors including many new and non-traditional competitors, (iii) ensure that our processes and solutions remain cost-competitive and (iv) attract, develop and retain individuals with the requisite technical expertise and understanding of customers’ needs to develop and sell new technologies and processes.

Table of Contents

We may not be able to maintain our manufacturing, engineering and technological expertise.

The markets for our processes and solutions are characterized by changing technology and evolving process development. The continued success of our business will depend upon our ability to:

●

hire, retain and expand our pool of qualified engineering and trade-skilled personnel;

●

maintain technological leadership in our industry;

●

implement new and expand upon current robotics, automation and tooling technologies; and

●

anticipate or respond to changes in manufacturing processes in a cost-effective and timely manner.

We cannot be certain that we will develop the capabilities required by our customers in the future. The emergence of new technologies, industry standards or customer requirements may render our equipment, inventory or processes obsolete or uncompetitive. We may have to acquire new technologies and equipment to remain competitive. The acquisition and implementation of new technologies and equipment may require us to incur significant expense and capital investment, which could reduce our margins and affect our operating results. When we establish or acquire new facilities, we may not be able to maintain or develop our manufacturing, engineering and technological expertise due to a lack of trained personnel, effective training of new staff or technical difficulties with machinery. Failure to anticipate and adapt to customers’ changing technological needs and requirements or to hire and retain a sufficient number of engineers and maintain manufacturing, engineering and technological expertise may have a material adverse effect on our business, operating results and financial condition.

We are dependent on a limited number of large customers for current and future net sales. The loss of any of these customers or the loss of market share by these customers could materially adversely affect our business, financial condition, results of operations and cash flows.

We depend on a limited number of major manufacturers for a substantial portion of our net sales. For example, our largest customers in 2025 included PACCAR Inc. and John Deere which accounted for 13.6% and 10.0% of our net sales, respectively. Our financial performance depends in large part on our ability to continue to arrange for the purchase of our processes and solutions with these customers, and we expect these customers to continue to make up a large portion of our net sales in the foreseeable future. The loss of all or a substantial portion of our sales to any of our large-volume customers could have a material adverse effect on our business, financial condition, results of operations and cash flows by reducing cash flows and by limiting our ability to spread our fixed costs over a larger net sales base. We may make fewer sales to these customers for a variety of reasons, including, but not limited to:

●

loss of business relationship;

●

reduced or delayed customer requirements;

●

the insourcing of business that has been traditionally outsourced to us;

●

strikes or other work stoppages affecting production by our customers; or

●

reduced demand for our customers’ products, including as a result of inflationary pressures, elevated interest rates and/or geopolitical events.

Entering new markets, either organically or via acquisition, poses new competitive threats and commercial risks.

As we expand into new markets, either organically or via acquisition, we expect to diversify our net sales by leveraging our development, engineering and manufacturing capabilities in order to source necessary parts and components for other industries. Such diversification requires investments and resources that may not be available as needed. Furthermore, even if we sign contracts in new markets, we cannot guarantee that we will be successful in leveraging our capabilities into these new markets and thus in meeting the

Table of Contents

needs of these new customers and competing favorably in these new markets. If these new customers experience reduced demand for their products or financial difficulties, our future prospects will be negatively affected as well.

We depend on our key executive officers, managers, and trade-skilled personnel and may have difficulty retaining and recruiting qualified employees. Moreover, we operate in competitive labor markets, which may also impact our ability to hire and retain employees at our facilities.

Our success depends to a large extent upon the continued services of our executive officers, senior management, managers and trade-skilled personnel and our ability to recruit and retain skilled personnel to maintain and expand our operations. We could be affected by the loss of any of our executive officers who are responsible for formulating and implementing our business plan and strategy, and who are instrumental to our growth and development. In addition, we need to recruit and retain additional management personnel and other skilled employees at our facilities. However, competition for our trade-skilled labor is high, particularly in some of the geographic locations where our facilities are located. Although we intend to continue to devote significant resources to recruit, train and retain qualified employees, we may not be able to attract, effectively train and retain these employees. Any failure to do so could impair our ability to conduct design, engineering and manufacturing activities, efficiently perform our contractual obligations, develop marketable components, timely meet our customers’ needs and ultimately win new business, all of which could adversely affect our business, financial condition and results of operations. If we are not able to do so, our business and our ability to continue to grow could be negatively affected. In addition, salaries and related costs are a significant portion of the cost of providing our solutions and, accordingly, our ability to efficiently utilize our workforce impacts our profitability.

Macroeconomic conditions impacting data center & critical power end-market demand could have a material adverse impact on our business, financial condition, results of operations and cash flows.

Our recent acquisition of Accu-Fab, LLC has significantly increased our exposure to the Data Center & Critical Power end market. As a result, our future financial performance is increasingly dependent on sustained growth and continued capital investment within this end market. Adverse developments including evolving government regulation, macroeconomic or geopolitical developments, reduced capital spending by Data Center & Critical Power customers or delays or cancellations of project launches could negatively impact order volumes and demand, and may limit our ability to realize the anticipated revenue synergies from the Accu-Fab acquisition. If any of these risks materialize, our business, financial condition, results of operations, and cash flows could be materially and adversely affected.

Availability of, and volatility in the prices of, raw materials and energy prices and our ability to pass along increased costs to our customers could adversely affect our results of operations.

The prices and availability of raw materials critical to our business and performance are based on global supply and demand conditions. Certain raw materials used by us are only available from a limited number of suppliers, and it may be difficult to find alternative suppliers at the same or similar costs. While we strive to pass through the price of raw materials to our customers, we may not be able to do so in the future, and volatility in the prices of raw materials (including as a result of macroeconomic conditions and geopolitical events) may affect customer demand for certain components. In addition, we, along with our suppliers and customers, rely on various energy sources for a number of activities connected with our business, such as the transportation of raw materials and finished parts. The availability and pricing of these resources are subject to market forces that are beyond our control. Furthermore, we are vulnerable to any reliability issues experienced by our suppliers, which also are beyond our control. Our suppliers contract separately for the purchase of such resources, and our sources of supply could be interrupted should our suppliers not be able to obtain these materials due to higher demand or other factors that interrupt their availability (including as a result of macroeconomic conditions and geopolitical events). Energy and utility prices, including electricity and water prices, and in particular prices for petroleum-based energy sources, are volatile. Increased supplier and customer operating costs arising from volatility in the prices of energy sources, such as increased energy and utility costs and transportation costs, could be passed through to us and we may not be able to increase our product prices sufficiently or at all to offset such increased costs. The impact of any volatility in the prices of energy or the raw materials on which we rely, including the reduction in demand for certain components caused by such price volatility, could result in a loss of net sales and profitability and adversely affect our results of operations.

Table of Contents

Our manufacturing operations are dependent upon third-party suppliers, making us vulnerable to supply shortages.

We obtain raw materials, parts and certain components from third-party suppliers. Any delay in receiving supplies could impair our ability to timely deliver components to our customers and, accordingly, could have an adverse effect on our business, financial condition, results of operations and cash flows. The volatility in the financial markets and uncertainty in the sectors our suppliers service could result in exposure related to the financial viability of certain of our suppliers. Suppliers may also exit certain business lines, causing us to find other suppliers for materials or components and potentially delaying our ability to deliver components to customers, or our suppliers may change the terms on which they are willing to provide parts or materials to us, any of which could adversely affect our financial condition and results of operations. In addition, many of our suppliers have unionized workforces that could be subject to work stoppages as a result of labor relations issues. Some of our suppliers supply components and materials that cannot be quickly or inexpensively re-sourced to another supplier due to long lead times and contractual commitments that might be required by another supplier in order to provide the components or materials.

Our growth strategy includes acquisitions, and we may not be able to identify attractive acquisition targets or successfully integrate acquired targets without impacting our business.

Acquisitions have played a key role in our growth strategy, and we expect to continue to grow through acquisitions in the future. We expect to continue evaluating potential strategic acquisitions of businesses, assets and product lines. We may not be able to identify suitable candidates, negotiate appropriate or favorable acquisition terms, obtain financing that may be needed to consummate such transactions or complete proposed acquisitions. There is significant competition for acquisition and expansion opportunities in our businesses, which may increase the cost of any acquisition or result in the loss of attractive acquisition targets.

In addition, acquisitions involve numerous risks, including (i) incurring the time and expense associated with identifying and evaluating potential acquisitions and negotiating potential transactions, resulting in management’s attention being diverted from the operation of our existing business; (ii) using estimates and judgments to evaluate credit, operations, funding, liquidity, business, management and market risks with respect to the target entity or assets; (iii) litigation relating to an acquisition, particularly in the context of a publicly held acquisition target, could require us to incur significant expenses or result in the delaying or enjoining of the transaction; (iv) failing to properly identify an acquisition candidate’s liabilities, potential liabilities or risks; (v) not receiving required regulatory approvals or such approvals being delayed or restrictively conditional; and (vi) the ability to retain customers following the completion of an acquisition. In addition, any acquisitions could involve the incurrence of substantial additional indebtedness or dilution to our shareholders. We cannot assure you that we will be able to successfully integrate any acquisitions that we undertake or that such acquisitions will perform as planned or prove to be beneficial to our operations and cash flow. Any such failure could seriously harm our financial condition, results of operations and cash flows.

We routinely evaluate potential acquisition candidates and engage in discussions and negotiations regarding potential acquisitions; however, even if we execute a definitive agreement for an acquisition, there can be no assurance that we will consummate the transaction within the anticipated closing timeframe, or at all. Further, acquisitions typically involve the payment of a premium over book- and market-value for the target business or asset and, therefore, some dilution of our tangible book value and/or earnings per common share may occur in connection with any future transaction.

The impact of foreign trade relations and associated tariffs, as well as our reliance on international suppliers for certain raw materials, could adversely impact our business.

We currently source certain raw materials from international suppliers. Import tariffs, taxes, customs duties and/or other trade regulations imposed by the U.S. government on foreign countries, or by foreign countries on the United States, have in the past and could in the future, significantly increase the prices we pay for certain raw materials, such as steel, aluminum and purchased components, that are critical to our ability to manufacture components for our customers. The international sourcing for these materials may also be hurt by health concerns regarding infectious diseases in countries in which these materials are purchased from, adverse weather, natural disasters or geopolitical events. In addition, we may be unable to find a domestic supplier to provide the necessary raw materials on an economical basis in the amounts we require. If the cost of our raw materials increases, or if we are unable to procure the necessary raw materials required to manufacture our components, then we could experience a negative impact on our operating results, profitability, customer relationships and future cash flows.

Table of Contents

Additionally, our customers’ businesses have been, and may continue to be in the future, negatively impacted by import tariffs, taxes, customs duties and/or other trade regulations imposed by the U.S. government on foreign countries or by foreign countries on the United States, which has, and in the future could, in turn, reduce our customers’ demand for the components that we manufacture for them. Any further reduction in customer demand for our components as a result of actual or threatened tariffs, taxes, customs duties and/or other trade regulations, or as a result of the impact of infectious diseases, could have a material adverse impact on our financial position, results of operations, cash flows and liquidity.

Geopolitical and economic developments could adversely affect our business.

Geopolitical events, increased political instability and social unrest, evidenced by the threat or occurrence of terrorist attacks or conflicts, enhanced national security measures, the risks related to epidemics and the related decline in consumer confidence may hinder our ability to do business. Any escalation in these events or similar future events may disrupt our operations or those of our customers and suppliers and could affect the availability of raw materials and components we need in our manufacturing operations or the means to transport those materials or components to our manufacturing facilities and finished parts to our customers. These events have had and may continue to have an adverse effect, generally, on the economy and consumer confidence and spending, which could adversely affect our net sales and operating results. The effect of these events on the volatility of the financial markets could in the future lead to volatility of the market price of our securities and may limit the capital resources available to us, our customers and our suppliers.

Increases in the cost of employee benefits could impact our financial results and cash flows.

Our expenses relating to employee health benefits are significant. Unfavorable changes in the cost of and the unpredictability of claims under such benefits, including inflationary pressures on wages and benefits, could impact our financial results and cash flows. Healthcare costs have risen significantly in recent years, and recent legislative and private sector initiatives regarding healthcare reform could result in significant changes to the U.S. healthcare system. Due to the breadth and complexity of the healthcare reform legislation and the uncertainty surrounding further reform proposals, we are not able to fully determine the impact that healthcare reform will have in the future on company sponsored medical plans.

If we fail to develop new and innovative processes or if customers in our market do not accept them, our results would be negatively affected.

Our processes must be kept current to meet our customers’ needs. To remain competitive, we therefore must develop new and innovative processes on an ongoing basis. If we fail to make innovations or the market does not accept our new processes, our sales and results would suffer. We invest significantly in the research and development of new processes; however, these expenditures do not always result in processes that will be accepted by the market. To the extent they do not, whether as a function of the process or the business cycle, we will have increased expenses without significant sales to offset such costs. Failure to develop successful new processes may also cause potential customers to purchase from competitors.

We are dependent on information technology and our systems and infrastructure face certain risks, including cybersecurity risks and data leakage risks.

We are dependent on information technology systems and infrastructure that could be damaged or interrupted by a variety of factors. Any significant breach, breakdown, destruction or interruption of these systems by employees, others with authorized access to our systems or unauthorized persons has the potential to negatively affect our operations. There is also a risk that we could experience a business interruption, theft of information or reputational damage as a result of a cyberattack, such as the infiltration of a data center, denial-of-service attacks, viruses, malicious software, phishing attacks, security breaches or data leakage of confidential information either internally or at our third-party providers. Although we have invested in the protection of our data and information technology to reduce these risks and periodically test the security of our information systems network, there can be no assurance that our efforts will prevent breakdowns or breaches in our systems that could have a material adverse effect on our financial condition, results of operations and liquidity.

We may incur additional expenses and delays due to technical problems or other interruptions at our manufacturing facilities.

Disruptions in operations due to technical problems or power interruptions as well as other interruptions such as floods, fire, other natural disasters, epidemics or pandemics could adversely affect the manufacturing capacity of our facilities. Such interruptions could cause delays in production and cause us to incur additional expenses such as charges for expedited deliveries for components that are delayed. In addition, our customers have the ability to cancel purchase orders in the event of any delays in production and may decrease future orders if delays are persistent. Additionally, to the extent that such disruptions do not result from damage to our physical property, these may not be covered by our business interruption insurance. Any such disruptions may adversely affect our operations and financial results.

The risks associated with climate change, as well as climate change legislation and regulations, could adversely affect our operations and financial condition.

The physical risks of climate change, such as more frequent or more extreme weather events, changes in temperature and precipitation patterns, changes to ground and surface water availability and other related phenomena, could affect some, or all, of our operations, as well as the operations of our customers and suppliers. Severe weather or other natural disasters could be destructive, which could result in increased costs, including supply chain costs.

In addition, a number of government bodies have finalized, proposed or are contemplating legislative and regulatory changes in response to concerns about climate change. In recent years, federal, state and local governments have taken steps to reduce emissions of greenhouse gases (GHGs). The Environmental Protection Agency has finalized a series of GHG monitoring, reporting and emissions control rules for certain large sources of GHGs, and the U.S. Congress has, from time to time, considered adopting legislation to reduce GHG emissions. Numerous states have already taken measures to reduce GHG emissions, primarily through the development of GHG emission inventories and/or regional GHG cap-and-trade programs.

Although it is not possible at this time to predict how future legislation or regulations to address GHG emissions would impact our business, any such laws and regulations imposing reporting obligations on, or limiting emissions of GHGs from, our equipment and operations, could require us to incur costs to reduce GHG emissions associated with our operations. We cannot assure you that our costs, liabilities and obligations relating to environmental matters will not have a material adverse effect on our business, financial condition, results of operations and cash flows.

Our manufacturing, painting and coating operations are subject to environmental, health and safety laws and regulations that could result in liabilities to us.

Our manufacturing, painting and coating operations are subject to environmental, health and safety laws and regulations, including those governing discharges to air and water, the management and disposal of hazardous substances, the cleanup of contaminated sites and health and safety matters. We could incur material costs, including cleanup costs, civil and criminal fines, penalties and third-party claims for cost recovery, property damage or personal injury as a result of violations of or liabilities under such laws and regulations. The ultimate cost of remediating contaminated sites, if any, is difficult to accurately predict and could exceed estimates. In addition, as environmental, health and safety laws and regulations have tended to become stricter, we could incur additional costs complying with requirements that are promulgated in the future.

If our manufacturing processes do not comply with applicable statutory and regulatory requirements, or if we manufacture components containing manufacturing defects, demand for our capabilities may decline and we may be subject to liability claims.

Our manufacturing processes and facilities need to comply with applicable statutory and regulatory requirements. We may also have the responsibility to ensure that the processes we use satisfy safety and regulatory standards, including those applicable to our customers and to obtain any necessary certifications. In addition, our customers’ products, as well as the manufacturing processes and components that we use to produce such products, are often highly complex. As a result, components that we manufacture may at times contain manufacturing defects, and our manufacturing processes may be subject to errors or not be in compliance with applicable statutory and regulatory requirements or demands of our customers. Defects in the components we manufacture, whether caused by a manufacturing or component failure or error, or deficiencies in our manufacturing processes, may result in delayed shipments to customers, replacement costs or reduced or cancelled customer orders. If these defects or deficiencies are significant, our business reputation may also be damaged. The failure of the components that we manufacture for our customers to comply with

Table of Contents

applicable statutory and regulatory requirements may subject us to legal fines or penalties and, in some cases, require us to shut down or incur considerable expense to correct a manufacturing process or facility. In addition, these defects may expose us to liability to pay for the recall of a customer’s product or to indemnify our customers for the costs of any such claims or recalls which they face as a result of using items manufactured by us in their products.

Adverse judgments or settlements in legal disputes, including product liability, intellectual property infringement and other claims, could result in materially adverse monetary damages or injunctive relief and damage our business and/or our reputation.

We are subject to, and may become a party to, a variety of litigation or other claims and suits that arise from time to time in the ordinary course of our business. The results of litigation and other legal proceedings are inherently uncertain and adverse judgments or settlements in some or all of these legal disputes may result in materially adverse monetary damages or injunctive relief against us, or in other adverse consequences to our financial condition and results of operations. Additionally, our insurance policies may not protect us against potential liability due to various exclusions in the policies and self-insured retention amounts. Partially or completely uninsured claims, if successful and of significant magnitude, could have a material adverse effect on our business, financial condition and results of operations. Furthermore, any claims or litigation, even if fully indemnified or insured, could damage our reputation and make it more difficult to compete effectively or obtain adequate insurance in the future.

The components we manufacture can expose us to potential liabilities. For instance, our manufacturing operations expose us to potential product liability claims resulting from injuries caused by defects in components we design or manufacture, as well as potential claims that components we design infringe on third-party intellectual property rights. Such claims could subject us to significant liability for damages, subject the infringing portion of our business to injunction and, regardless of their merits, could be time-consuming and expensive to resolve. We may also have greater potential exposure from warranty claims and recalls due to problems caused by component or product design. Although we have product liability insurance coverage, it may not be sufficient to cover the full extent of our product liability, if at all. A successful product liability claim in excess or outside of our insurance coverage or any material claim for which insurance coverage was denied or limited and for which indemnification was not available could have a material adverse effect on our business, results of operations and/or financial condition.

Any failure to protect our customers’ intellectual property that we use in the products we manufacture for them could harm our customer relationships and subject us to liability.

The products we manufacture for our customers often contain our customers’ intellectual property, including copyrights, patents, trade secrets and know-how. Our success depends, in part, on our ability to protect our customers’ intellectual property. The steps we take to protect our customers’ intellectual property may not adequately prevent its disclosure or misappropriation. If we fail to protect our customers’ intellectual property, our customer relationships could be harmed, and we may experience difficulty in establishing new customer relationships. In addition, our customers might pursue legal claims against us for any failure to protect their intellectual property, possibly resulting in harm to our reputation and our business, financial condition and operating results.

Compliance or the failure to comply with regulations and governmental policies could cause us to incur significant expense.

We are subject to a variety of local and foreign laws and regulations including those relating to labor and health and safety concerns. Such laws may require us to pay mandated compensation and penalties. Additionally, we may need to obtain and maintain licenses and permits to conduct business in various jurisdictions. If we or the businesses or companies we acquire have failed or fail in the future to comply with such laws and regulations, then we could incur liabilities and fines and our operations could be suspended. Such laws and regulations could also restrict our ability to modify or expand our facilities, could require us to acquire costly equipment, or could impose other significant expenditures.

Because our industry is capital intensive and we have significant fixed and semi-fixed costs, our profitability is sensitive to changes in volume.

The property, plants and equipment needed to produce components for our customers and provide our processes and solutions can be very expensive. We must spend a substantial amount of capital to purchase and maintain such property, plants and equipment. Although we believe our current cash balance, along with our projected internal cash flows and available financing sources, will provide sufficient cash to support our currently anticipated operating and capital needs, if we are unable to generate sufficient cash to

Table of Contents

purchase and maintain the property, plants and equipment necessary to operate our business, we may be required to reduce or delay planned capital expenditures or to incur additional indebtedness.

Prior to the completion of our initial public offering we were 100% owned by the Mayville Engineering Company, Inc. Employee Stock Ownership Plan (ESOP), which is a retirement plan intended to be tax-qualified. If the ESOP fails to meet the requirements of a tax-qualified retirement plan, we could be subject to substantial penalties.

The ESOP, is a defined contribution retirement plan subject to the requirements of the Internal Revenue Code of 1986, as amended (the Code), and the Employee Retirement Income Security Act of 1974, as amended (ERISA). The ESOP has received a determination letter from the Internal Revenue Service (IRS) that it meets the requirements of a tax-qualified retirement plan in form and we endeavor to maintain and administer the ESOP in compliance with all requirements of the Code and ERISA. However, the rules regarding tax-qualified plans, and especially ESOPs, are complex and change frequently. Accordingly, it is possible that the ESOP may not have been and may not in the future be administered in full compliance with all applicable rules under the Code or ERISA.

If the IRS were to determine that the ESOP was not in material compliance with the Code or ERISA, then the ESOP could lose its tax-qualified status and we could be subject to substantial penalties under the Code and/or ERISA, which could have a material adverse effect on our business, financial condition or results of operations.

Risks Related to Our Indebtedness

Our Amended and Restated Credit Agreement, as amended, restricts our ability and the ability of our subsidiaries to engage in some business and financial transactions.

On June 28, 2023, and as amended on June 26, 2025, we entered into an amended and restated credit agreement (the Credit Agreement) with certain lenders and Wells Fargo Bank, National Association, as administrative agent (the Agent). The Credit Agreement provides for a $350,000 revolving credit facility, with a letter of credit sub-facility, and a swingline facility in an aggregate amount of $25,000. All amounts borrowed under the Credit Agreement mature on June 28, 2028.

Our Credit Agreement contains a number of covenants that limit our ability and the ability of our subsidiaries to:

●

create, incur or assume indebtedness (other than certain permitted indebtedness);

●

create or incur liens (other than certain permitted liens);

●

make investments (other than certain permitted investments);

●

merge or consolidate with another entity;

●

make asset dispositions (other than certain permitted dispositions);

●

declare or pay any dividend or any other distribution to shareholders;

●

enter into transactions with affiliates;

●

make certain organizational changes, including changing our fiscal year end or amending our organizational documents;

●

enter into any agreement further restricting our ability to create or assume any lien;

●

sell notes receivable or accounts receivable except under certain circumstances;

●

enter into sale leaseback transactions;

Table of Contents

●

incur capital expenditures in excess of $50.0 million in any fiscal year;

●

permit any person or group other than the ESOP or other employee benefit plan of ours (like our 401(k) plan) to own or control more than 35% of our equity interests; or

●

permit our Board of Directors to not be composed of a majority of our continuing directors (i.e., our directors as of September 26, 2019 and any additional or replacement directors that have been approved by at least 51% of the directors then in office).

Our Credit Agreement also requires us to maintain a minimum interest coverage ratio and a consolidated total leverage ratio, and contains certain customary representations and warranties, affirmative covenants and events of default (including, among others, payment default, covenant default, breach of representation or warranty, bankruptcy, cross-default, material ERISA events, material money judgements and failure to maintain subsidiary guarantees).

As a result of the Accu-Fab acquisition, we have incurred additional indebtedness. This incremental borrowing has increased our consolidated total leverage ratio, resulting in the Company approaching the maximum permitted leverage ratio under the terms of our Credit Agreement. Should our operating performance decline or should additional indebtedness be incurred, there is a risk that we may not remain in compliance with the leverage ratio covenant. Non-compliance with this covenant could result in an event of default. If an event of default occurs under the Credit Agreement, the lenders under the Credit Agreement will be entitled to take various actions, including the acceleration of amounts due thereunder, the termination of such credit facility and all actions permitted to be taken by a secured creditor. Our failure to comply with our obligations under the Credit Agreement may result in an event of default under the Credit Agreement. A default, if not cured or waived, may permit acceleration of our indebtedness. If our indebtedness is accelerated, we cannot be certain that we will have sufficient funds available to pay the accelerated indebtedness or that we will have the ability to refinance the accelerated indebtedness on terms favorable to us or at all.

On February 25, 2026, we entered into an amendment to the Credit Agreement. The February 25, 2026, amendment lowered the amount of total available borrowings under the revolving credit facility to $275,000 from $350,000. The letter of credit sub-facility and swingline facility remained unchanged. All amounts borrowed under the credit agreement mature on June 28, 2028. The amendment also amends our existing financial covenants and includes additional interest rate pricing tiers based on those financial covenants, with all other material terms of the Credit Agreement remaining unchanged.

We are able to incur additional debt, which could reduce our ability to satisfy our current obligations under our existing indebtedness.

At December 31, 2025, we had $202.5 million outstanding under our revolving credit facility. In addition, we may be able to incur significant additional indebtedness in the future, and we may do so, among other reasons, to fund acquisitions as part of our growth strategy. Although the Credit Agreement contains restrictions on the incurrence of additional indebtedness, these restrictions are subject to a number of qualifications and exceptions, and we could incur substantial additional indebtedness in compliance with these restrictions.

Risks Related to Ownership of Our Common Stock

Your ability to influence corporate matters may be limited because the ESOP and our 401(k) plan own a substantial amount of our stock and continue to have significant influence over us, which may limit your ability to influence the outcome of important transactions, including a change in control.

As of December 31, 2025, our employees and certain former employees, through their interests in the ESOP and the Mayville Engineering Company, Inc. 401(k) Plan (the 401(k) Plan), beneficially owned approximately 22% of the outstanding shares of our common stock. Each participant in the ESOP and the 401(k) Plan is entitled to direct the vote of the shares allocated to his or her accounts, in his or her sole discretion. As a result, our employees and former employees, if acting together, will be able to significantly influence matters requiring approval by our shareholders, including the election of directors, influence over our management and policies and the approval of mergers, acquisitions or other extraordinary transactions. As employees and former employees, the ESOP and 401(k) Plan participants’ interests may be contrary to other investors. This concentration of ownership may have the effect of

Table of Contents

delaying, preventing or deterring a change in control of our company, could deprive our non-ESOP and non-401(k) Plan shareholders of an opportunity to receive a premium for their common stock as part of a sale of our company and might ultimately affect the market price of our common stock.

The Trustees of the ESOP and the 401(k) Plan may have the power to vote a large block of shares on matters presented to shareholders for approval.

ESOP and 401(k) Plan participants have the right to direct the vote of the shares allocated to his or her ESOP and 401(k) Plan accounts. However, if a participant does not timely direct the voting of his or her shares, then (1) GreatBanc Trust Company (the ESOP Trustee) will vote such shares in its independent fiduciary discretion and (2) Principal Trust Company (the 401(k) Plan Trustee) will vote such shares as directed by the 401(k) Plan sponsor, which is the Company. Additionally, the ESOP Trustee and the 401(k) Plan Trustee have fiduciary duties under ERISA which may cause the ESOP Trustee or the 401(k) Plan Trustee to override participants’ voting discretions. Consequently, there may be circumstances in which the ESOP Trustee and the 401(k) Plan Trustee have the ability to vote a significant block of shares on matters presented to shareholders for approval. The ESOP and the 401(k) Plan, which as retirement plans have the purpose of providing retirement benefits to current and former employees of the Company and their beneficiaries, may have interests that are different from other investors and may vote in a way with which other shareholders disagree and which may be adverse to other shareholders interests.

The market price of our common stock may be volatile, and you could lose all or part of your investment.

Since our initial public offering in May 2019, the market price of our common stock has been volatile and has been and could continue to be subject to wide fluctuations in response to various factors, some of which are beyond our control. These fluctuations could cause investors to lose all or part of their investment in our common stock. Factors that could cause fluctuations in the market price of our common stock include the following: general economic and geopolitical conditions, inflation, interest rates, tariffs, fuel prices, international currency fluctuations and acts of war or terrorism; price and volume fluctuations in the overall stock market from time to time; actual or anticipated fluctuations in our quarterly financial results or the quarterly financial results of companies perceived to be similar to us; changes in the market’s expectations about our operating results; changes in our orders in a given period; success of competitors; our operating results failing to meet the expectation of securities analysts or investors in a particular period; changes in financial estimates and recommendations by securities analysts concerning us or the markets in general; operating and stock price performance of other companies that investors deem comparable to us; our ability to manufacture new and enhanced components for the products of our customers on a timely basis; changes in laws and regulations affecting our business; commencement of, or involvement in, litigation involving us; changes in our capital structure, such as future issuances of securities or the incurrence of additional debt; the volume of securities available for public sale; sales of substantial amounts of our securities by our directors, executive officers or significant shareholders (including our current and former employees via the ESOP and the 401(k) Plan) or the perception that such sales could occur; any major change in our Board of Directors or management; and changes in our investor base.

We do not expect to declare any dividends in the foreseeable future.

The continued operation and growth of our business, including acquisitions and capital expenditures, will require substantial cash. Accordingly, we do not anticipate declaring any cash dividends to holders of our common stock in the foreseeable future. Any determination to pay dividends in the future will be at the discretion of our Board of Directors and will depend upon results of operations, financial condition, any contractual restrictions, our indebtedness, restrictions imposed by applicable law and other factors our Board of Directors deem relevant. Consequently, investors may need to sell all or part of their holdings of our common stock after price appreciation, which may never occur, as the only way to realize any future gains on their investment.

Some provisions of Wisconsin law and our articles of incorporation and bylaws could make a merger, tender offer or proxy contest difficult, thereby depressing the trading price of our common stock.

Our status as a Wisconsin corporation and the anti-takeover provisions of the Wisconsin Business Corporation Law (the WBCL) may discourage, delay or prevent a change in control even if a change in control would be beneficial to our shareholders by prohibiting us from engaging in a business combination with an interested shareholder for a period of three years after the person becomes an interested shareholder. We may engage in a business combination with an interested shareholder after the expiration of the three-year period with respect to that shareholder only if one or more of the following conditions is satisfied: (i) our Board of

Table of Contents

Directors approved the acquisition of the stock before the date on which the shareholder acquired the shares, (ii) the business combination is approved by a majority of our outstanding voting stock not beneficially owned by the interested shareholder or (iii) the consideration to be received by shareholders meets certain fair prices requirements of the WBCL with respect to form and amount.

In addition, our articles of incorporation and bylaws contain provisions that may make the acquisition of the company more difficult, including the following:

●

establishing a classified Board of Directors so that not all members of our Board of Directors are elected at one time, which could delay the ability of shareholders to change the membership of a majority of our Board of Directors;

●

authorizing undesignated preferred stock, the terms of which may be established and shares of which may be issued by our Board of Directors without shareholder approval;

●

requiring certain procedures to be satisfied in order for a shareholder to call a special meeting of shareholders, including requiring that we receive written demands for a special meeting from holders of 10% or more of all the votes entitled to be cast on any issue proposed to be considered;

●

requiring that a director may be removed from office only for “cause” and with the affirmative vote of shareholders holding at least 66 2/3% of the then outstanding shares of stock entitled to vote in the election of directors;

●

not providing for cumulative voting in the election of directors, which would otherwise allow holders of less than a majority of stock to elect some directors; and

●

establishing advance notice procedures for shareholder proposals or the nomination of candidates for election as directors.

These provisions could have the effect of discouraging, delaying or preventing a transaction involving a change in control of the Company. These provisions could also have the effect of discouraging proxy contests and make it more difficult for shareholders to elect directors of their choosing or prevent us from taking other corporate actions that shareholders may desire.

Item 1B. Unresolved Staff Comments.

None.

Item 1C. Cybersecurity.

The Company is committed to maintaining a strong cybersecurity posture devoting significant resources to cybersecurity and risk management processes to adapt to the rapidly evolving landscape and respond to emerging threats in a timely and effective manner. Our cybersecurity risk management program aligns with the National Institute of Standards and Technology (NIST) framework, which organizes cybersecurity risks into six categories: govern, identify, protect, detect, respond and recover. The Company has designed and implemented cybersecurity policies and procedures for identifying and managing material risk from cybersecurity threats, both internally and related to the use of third-party service providers. We use various tools and methodologies to manage cybersecurity risk that are tested on a regular basis. At the tactical level, our information technology (IT) security team regularly monitors alerts and meets to discuss threat levels, trends and remediation. The Company monitors and evaluates our cybersecurity position and performance on an ongoing basis through regular vulnerability scans, penetration tests and threat intelligence feeds. Additionally, the Company maintains a formal information security training program for all employees that includes training on matters such as phishing, email security best practices and data privacy. To evaluate and enhance our cybersecurity program, it is regularly evaluated by external experts with the results of those reviews reported to senior management and the Audit Committee of our Board of Directors (Audit Committee). We also actively engage with key vendors, industry participants and intelligence and law enforcement communities as part of our continuing efforts to evaluate and enhance the effectiveness of our information security policies and procedures.

Oversight of cybersecurity risk is maintained by the Company’s Board of Directors and is supported by the Audit Committee. The Audit Committee is primarily responsible for overseeing our design, execution and administration of the Company’s enterprise risk management process, and with regard to cybersecurity risks, setting expectations and accountability for management and reviewing management’s assessment of the effectiveness of our cybersecurity controls, including policies and procedures to address our cyber risks and overseeing the Company’s cybersecurity disclosures. The Company’s information security program is managed by the Company’s Chief Information Officer (CIO), whom reports to the Chief Financial Officer (CFO), and whose team is responsible for leading enterprise-wide cybersecurity strategy, policy, standards, architecture and processes. The CIO periodically briefs the Audit Committee and our CFO, as well as our Chief Executive Officer (CEO), other members of the Board of Directors and other members of our senior management as appropriate. These reports include, but are not limited to, new developments, evolving standards, vulnerability assessments, third-party and independent reviews, threat environment summaries and technological trends. In the event of

Table of Contents

a potentially material cybersecurity incident, the CIO will meet with the Company’s Audit Committee, CEO, CFO, legal counsel and any other members of senior management as appropriate to review the cybersecurity event, perform a materiality analysis and, if appropriate, identify any information required to be disclosed in a Current Report on Form 8-K.

As of the date of this report, the Company is not aware of any risks from cybersecurity threats, including as a result of any previous cybersecurity incidents, that have materially affected or are reasonably likely to materially affect us, our business strategy, results of operations or financial condition. However, there can be no assurances that a cybersecurity threat or incident that could have a material impact on the Company will not occur in the future. In response to the rapidly evolving cyber threat environment, the Company continues to invest in data security and system resiliency. See also Item 1A, “Risk Factors” for additional discussion regarding risks related to information technology systems.

Item 2. Properties.

We maintain owned and leased manufacturing and office facilities throughout the U.S. The Company’s corporate office is located in Milwaukee, Wisconsin. We believe that our facilities are sufficient to meet our current and near-term manufacturing needs.

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

Management’s Discussion and Analysis of Financial Condition and Results of Operations is intended to assist in understanding and assessing the trends and significant changes in our results of operations and financial condition. Historical results may not be indicative of future performance. This discussion includes forward-looking statements that reflect our plans, estimates and beliefs. Such statements involve risks and uncertainties. Our actual results may differ materially from those contemplated by these forward-looking statements as a result of various factors, including those set forth in “Risk Factors” in Part I, Item 1A and “Cautionary Statement Regarding Forward-Looking Statements” of this Annual Report on Form 10-K. This discussion should be read in conjunction with our audited consolidated financial statements and the notes thereto included in Part II, Item 8 of this Annual Report on Form 10-K. In this discussion, we use certain financial measures that are not prepared in accordance with accounting principles generally accepted in the United States of America (GAAP). Explanation of these non-GAAP financial measures and reconciliation to the most directly comparable GAAP financial measures are included in this Management’s Discussion and Analysis of Financial Condition and Results of Operations. Investors should not consider non-GAAP financial measures in isolation or as substitutes for financial information presented in compliance with GAAP.

All amounts are presented in thousands except share amounts, per share data, years and ratios.

Overview

MEC is a leading U.S.-based vertically-integrated, value-added manufacturing partner providing a full suite of manufacturing solutions from concept to production, including design, prototyping and tooling, fabrication, aluminum extrusion, coating, assembly and aftermarket components. Our customers operate in diverse end markets, including heavy- and medium-duty commercial vehicles, construction & access equipment, powersports, data center & critical power, agriculture, military and other end markets. We have developed long-standing relationships with our blue-chip customers based upon our commitment to “Unmatched Excellence”.

Our one operating segment focuses on producing metal components that are used in a broad range of heavy- and medium-duty commercial vehicles, construction & access equipment, powersports, data center & critical power, agricultural, military and other products.

Critical Accounting Estimates

The preparation of consolidated financial statements in conformity with GAAP requires management to make certain estimates and assumptions that affect the reported amounts and disclosures. Therefore, these estimates and assumptions affect reported amounts of assets, liabilities, revenue, expenses, and associated disclosures of contingent liabilities. Critical accounting estimates are those estimates that, in management’s view, are most important in the portrayal of our financial condition and results of operations. Management evaluates these estimates on an ongoing basis, using historical experience, consultation with third parties, and other methods considered reasonable in the particular circumstances. Nevertheless, actual results may differ significantly from our estimates. Any effects on our business, financial position, or results of operations resulting from revisions to these estimates are recognized in the accounting period in which the facts that give rise to the revision become known. The methods, estimates, and judgments that we use in applying our accounting estimates have a significant impact on the results that we report in our financial statements. These critical accounting estimates require us to make difficult and subjective judgments, often as a result of the need to make estimates regarding matters that are inherently uncertain. Those critical accounting estimates that require the most significant judgment or involve the selection or application of alternative accounting policies and are material to our consolidated financial statements are discussed further below.

Business Combinations

We record assets acquired and liabilities assumed in a business combination under the acquisition method of accounting where consideration is first assigned to identifiable assets and liabilities based on estimated fair values, with any excess recorded as goodwill. During the measurement period, which is up to one year from the acquisition date, we may adjust provisional amounts that were recognized at the acquisition date to reflect new information obtained about facts and circumstances that existed as of the acquisition date.

Determining the fair value of assets acquired and liabilities assumed requires significant judgment, including the selection of valuation methodologies. For our recent acquisition, fair value estimates of acquired property and equipment were based on independent appraisals that gave consideration to the highest and best use of the assets. The land, buildings, and improvements; and

Table of Contents

other property and equipment appraisals used one, or a combination, of the cost, market or sales comparison approaches. Significant estimates and assumptions, including recent sales prices of similar equipment, asset condition, and current and anticipated market trends, were used in determining the fair values of these assets. The assistance of an independent third-party valuation firm was used to determine the fair values and useful lives of the finite-lived intangible assets, including customer relationships and non-compete agreements. Valuation methods used were based on management’s forecasted cash inflows and outflows and using a relief from royalty method for developed technologies and the multi-period excess earnings method for customer relationships. Assumptions used in the intangible valuations include forecasted revenue growth rates, discounted future cash flows and the weighted average cost of capital of a select peer group.

Goodwill, Intangible Assets and Other Long-Lived Assets

Our long-lived assets consist primarily of property, equipment, purchased intangible assets and goodwill. The valuation and the impairment testing of these long-lived assets involve significant judgments and assumptions, particularly as they relate to the identification of reporting units, asset groups and the determination of fair value.

We test our tangible and intangible long-lived assets subject to amortization for impairment whenever facts and circumstances indicate that the carrying amount of an asset may not be recoverable. We test goodwill and indefinite lived intangible assets for impairment annually, or more frequently if triggering events occur indicating that there may be impairment.

We have recorded goodwill and performed testing for potential goodwill impairment at the reporting unit level. A reporting unit is an operating segment, or a business unit one level below an operating segment for which discrete financial information is available, and for which management regularly reviews the operating results. Additionally, components within an operating segment can be aggregated as a single reporting unit if they have similar economic characteristics. We have concluded we have one reporting unit.

We determine the fair value of our reporting unit using an income approach. Under the income approach, we calculate the fair value of a reporting unit based on the present value of estimated future cash flows. The income approach is dependent on several key management assumptions, including estimates of future sales, gross margins, operating costs, interest expense, income tax rates, capital expenditures, changes in working capital requirements and the weighted average cost of capital or the discount rate. Discount rate assumptions include an assessment of the risk inherent in the future cash flows of the reporting unit. Expected cash flows used under the income approach are developed in conjunction with our budgeting and forecasting process.

We test our goodwill for impairment on an annual basis, and more frequently if events or changes in circumstances indicate that it might be impaired. For the years ended December 31, 2025 and 2024, there were no events or changes in circumstances that would indicate an impairment of our goodwill.

Changes to management assumptions and estimates utilized in the income approach could negatively impact the fair value conclusions for our reporting unit resulting in goodwill impairment. All key assumptions and valuations are determined by and are the responsibility of management. The factors used in the impairment analysis are inherently subject to uncertainty. We believe that the estimates and assumptions are reasonable to determine the fair value of our reporting unit, however, if actual results are not consistent with these estimates and assumptions, goodwill and other intangible assets may be overstated which could trigger an impairment charge.

For impairment testing of long-lived assets, we identify asset groups at the lowest level for which identifiable cash flows are largely independent of the cash flows of other groups of assets and liabilities. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset group to estimated undiscounted future cash flow expected to be generated by the assets. If the carrying amount of an asset group exceeds its estimated future cash flows, an impairment charge is recognized by the amount by which the carrying amount of the asset exceeds the estimated fair value of the asset group. For the year ended December 31, 2025 and 2024, there were no events or changes in circumstances that indicated an impairment of our long-lived assets.

Determining the useful life of an intangible asset also requires judgment. Certain intangible assets are expected to have indefinite lives based on their history and our plans to continue to support and build the acquired brands. Other acquired intangible assets such as customer relationships, trade names, and non-compete agreements are expected to have determinable useful lives. The costs of determinable-lived intangibles are amortized to expense over their estimated lives.

Macroeconomic Conditions

The broader market dynamics over the past few years have resulted in impacts to the Company, elevated interest rates, inconsistent customer demand, material cost inflation and labor availability. The Company expects some of these dynamics to continue in 2026 and could continue to have an impact on demand, material costs and labor.

How We Assess Performance

Net Sales. Net sales reflect sales of our components and products net of allowances for returns and discounts. In addition to the current macroeconomic conditions, several factors affect our net sales in any given period, including weather, timing of acquisitions and the production schedules of our customers. Net sales are recognized at the time of shipment or at delivery to the customer.

Manufacturing Margins. Manufacturing margins represents net sales less cost of sales. Cost of sales consists of all direct and indirect costs used in the manufacturing process, including raw materials, labor, equipment costs, depreciation, lease expenses, subcontract costs and other directly related overhead costs. Our cost of sales is directly affected by the fluctuations in commodity prices, primarily sheet steel and aluminum, but these changes are largely mitigated by contractual agreements with our customers that allow us to pass through these price variations based upon certain market indexes.

Depreciation and Amortization. We carry property, plant and equipment on our balance sheet at cost, net of accumulated depreciation. Depreciation on property, plant and equipment is computed on a straight-line basis over the estimated useful life of the asset. The periodic expense related to leasehold improvements and intangible assets is depreciation and amortization expense, respectively. Leasehold improvements are depreciated over the lesser of the life of the underlying asset or the remaining lease term. Our intangible assets were recognized as a result of certain acquisitions and are generally amortized on a straight-line basis over the estimated useful lives of the assets.

Other Selling, General, and Administrative Expenses. Other selling, general and administrative expenses consist primarily of salaries and personnel costs for our sales and marketing, finance, human resources, information systems, administration and certain other managerial employees and certain corporate level administrative expenses such as incentive compensation, audit, accounting, legal and other consulting and professional services, travel, and insurance.

Other Key Performance Indicators

EBITDA, EBITDA Margin, Adjusted EBITDA, Adjusted EBITDA Margin and Free Cash Flow

EBITDA represents net income (loss) before interest expense (benefit), provision for income taxes, depreciation and amortization. EBITDA Margin represents EBITDA as a percentage of net sales for each period.

Adjusted EBITDA represents EBITDA before stock-based compensation, loss on extinguishment of debt, field replacement claim, legal costs due to former fitness customer, CFO transition costs, Chief Operating Officer (COO) restructuring costs, natural disaster costs, acquisition related costs, Wautoma and the restructuring plan (The Plan) restructuring charges, costs recognized on step-up of Mid-States Aluminum (MSA) and Accu-Fab acquired inventory and gain on lawsuit settlement. Adjusted EBITDA Margin represents Adjusted EBITDA as a percentage of net sales for each period.

Free cash flow represents net cash provided by operating activities less cash flow used in the purchase of property, plant and equipment.

These metrics are supplemental measures of our operating performance that are neither required by, nor presented in accordance with, GAAP. These measures should not be considered as an alternative to net income or any other performance measure derived in accordance with GAAP as an indicator of our operating performance. We present EBITDA, EBITDA Margin, Adjusted EBITDA, Adjusted EBITDA Margin and Free Cash Flow as management uses these measures as key performance indicators, and we believe they are measures frequently used by securities analysts, investors and other parties to evaluate companies in our industry. These measures have limitations as analytical tools and should not be considered in isolation or as substitutes for analysis of our results as reported under GAAP.

Our calculation of EBITDA, EBITDA Margin, Adjusted EBITDA, Adjusted EBITDA Margin and Free Cash Flow may not be comparable to the similarly named measures reported by other companies. Potential differences between our measures of EBITDA and Adjusted EBITDA compared to other similar companies’ measures of EBITDA and Adjusted EBITDA may include differences in capital structure and tax positions.

Net Sales. Net sales were $546,487 for the twelve months ended December 31, 2025 as compared to $581,604 for the twelve months ended December 31, 2024, a decrease of $35,117, or 6.0%. This decrease was driven by reduced customer demand across nearly all end markets and customer de-stocking channel inventory. This decline was partially offset by increased after-market demand in our Military end market and the acquisition of Accu-Fab driving Data Center & Critical Power volumes.

Manufacturing Margins. Manufacturing margins were $54,009 for the twelve months ended December 31, 2025 as compared to $71,097 for the twelve months ended December 31, 2024, a decrease of $17,088, or 24.0%. The decrease was primarily driven by softening customer demand, non-recurring restructuring costs, inventory step-up expense associated with the Accu-Fab acquisition and temporal launch-phase dynamics across projects in our Data Center & Critical Power and Commercial Vehicle markets, partially offset by cost reduction actions and higher-margin net sales contribution from the Accu-Fab acquisition.

Manufacturing margin percentages were 9.9% for the twelve months ended December 31, 2025 as compared to 12.2% for the twelve months ended December 31, 2024, a decrease of 2.3%. The decrease was attributable to the items discussed in the preceding paragraph.

Amortization of Intangible Assets. Amortization of intangible assets were $9,716 for the twelve months ended December 31, 2025 as compared to $6,933 for the twelve months ended December 31, 2024, an increase of $2,783, or 40.1%. The increase was due to amortization expense associated with identifiable intangible assets from the Accu-Fab acquisition. Refer to Note 2 – Acquisition for additional information related to these identifiable intangible assets.

Bonuses and Deferred Compensation Expenses. Bonuses and deferred compensation expenses were $8,724 for the twelve months ended December 31, 2025 as compared to $13,593 for the twelve months ended December 31, 2024, a decrease of $4,869, or 35.8%. The decrease was primarily driven by lower bonus accruals and stock-based compensation expense aligning with the Company financial performance.

Other Selling, General and Administrative Expenses. Other selling, general and administrative expenses were $39,413 for the twelve months ended December 31, 2025 as compared to $31,518 for the twelve months ended December 31, 2024, an increase of $7,895, or 25.0%. The increase was attributable to non-recurring costs and incremental SG&A expenses, each associated with Accu-Fab and higher costs related to compliance requirements. This was partially offset by lower legacy MEC wages and benefits.

Gain on Lawsuit Settlement. On October 28, 2024, the Company and a former fitness customer entered into a formal Settlement Agreement (the “Agreement”) resolving a previously disclosed lawsuit. Under the terms of the Agreement, the Company and the former fitness customer agreed to dismiss the lawsuit and exchange mutual releases, and MEC received a gross payment of $25,500 from the former fitness customer in the fourth quarter of 2024.

Interest Expense. Interest expense was $10,215 for the twelve months ended December 31, 2025 as compared to $10,989 for the twelve months ended December 31, 2024, a decrease of $774, or 7.0%. The decrease was due to reduced interest rates relative to the prior year period, partially offset by an increase in borrowings associated with the recent Accu-Fab acquisition.

Provision (benefit) for Income Taxes. Income tax benefit was $5,949 for the twelve months ended December 31, 2025 as compared to an expense of $7,596 for the twelve months ended December 31, 2024, a decrease of $13,545 or 178.3%. The decrease is primarily due to a pre-tax loss in the current year period compared to pre-tax income in the prior year period. The effective tax rate for the current period also reflects discrete tax benefits recognized during the twelve months ended December 31, 2025. Refer to Note 8 – Income Taxes of the Consolidated Financial Statements for further details.

Due to the factors described in the preceding paragraphs, net income (loss) and comprehensive income (loss), EBITDA, EBITDA Margin, Adjusted EBITDA and Adjusted EBITDA Margin decreased during 2025.

Cash Flows Analysis Twelve Months Ended December 31, 2025 Compared to Twelve Months Ended December 31, 2024

Operating Activities. Cash provided by operating activities was $38,562 for the twelve months ended December 31, 2025 as compared to $89,807 for the twelve months ended December 31, 2024. The $51,245 decrease was driven in part by the $25,500 lawsuit settlement payment received in the fourth quarter of the prior year. The remaining $25,745 was primarily due to lower net income (loss) adjusted for reconciling items and a higher use of cash associated with stabilized inventory levels in the current year as compared to inventory reductions in the prior-year period. In addition, cash usage increased due to lower accrued liabilities due to reduced bonus accruals aligning with the Company’s financial performance. This was partially offset by an increase in accounts payable due to the timing of supplier payments.

Investing Activities. Cash used in investing activities was $151,530 for the twelve months ended December 31, 2025, as compared to $11,712 for the twelve months ended December 31, 2024. The $139,818 increase in cash used in investing activities was mainly due to the acquisition of Accu-Fab completed on July 1, 2025, partially offset by a decrease in capital expenditures.

Financing Activities. Cash provided by financing activities was $114,264 for the twelve months ended December 31, 2025, as compared to cash used in financing activities of $78,561 for the twelve months ended December 31, 2024. The change was primarily due to borrowings in excess of debt repayments during the current year period on the Company’s revolving credit facility. Additionally, under the share repurchase plan, the Company purchased $4,607 of common stock during 2025 as compared to $5,896 in the prior-year period.

Amended and Restated Credit Agreement

Borrowings under the Credit Agreement bear interest at a fluctuating secured overnight financing rate (SOFR) plus an applicable margin based on the current consolidated total leverage ratio (which may be adjusted for certain reserve requirements), plus 1.25% to 2.75% depending on the current Consolidated Total Leverage Ratio (as defined in the Credit Agreement). Under certain circumstances, we may not be able to pay interest based on SOFR. If that happens, we will be required to pay interest at the Base Rate, which is the sum of the higher of (i) the Prime Rate (as publicly announced by the Agent from time to time), (ii) the Federal Funds Rate plus 0.50%, and (iii) Adjusted Term SOFR for a one-month tenor in effect on such day plus 1.00%.

At December 31, 2025, the interest rate on outstanding borrowings under the Revolving Loan was 5.98%. We had availability of $17,730 under the revolving credit facility at December 31, 2025.

We must pay a commitment fee of 0.20% to 0.35% per annum on the average daily unused portion of the aggregate unused revolving commitments under the Credit Agreement. At December 31, 2025, this fee was 0.30%. We must also pay fees as specified in the Fee Letter (as defined in the Credit Agreement) and with respect to any letters of credit issued under the Credit Agreement.

The Credit Agreement contains usual and customary negative covenants for agreements of this type, including, but not limited to, restrictions on our ability to, subject to certain exceptions, create, incur or assume indebtedness; create, incur, assume or suffer to exist liens; make certain investments; allow our subsidiaries to merge or consolidate with another entity; make certain asset dispositions; pay certain dividends or other distributions to shareholders; enter into transactions with affiliates; enter into sale leaseback transactions; and exceed the limits on annual capital expenditures. The Credit Agreement also requires us to satisfy certain financial covenants, including a minimum interest coverage ratio of 3.00 to 1.00. At December 31, 2025, our interest coverage ratio was 5.47 to 1.00. The Credit Agreement also requires us to maintain a consolidated total leverage ratio not to exceed 3.50 to 1.00. This ratio increases to 4.00 to 1.00 for the four quarters following an acquisition provided the acquisition meets certain agreed upon terms. The Accu-Fab acquisition on July 1, 2025 met these terms. As of December 31, 2025, our consolidated total leverage ratio was 3.68 to 1.00.

The Credit Agreement includes customary events of default, including, among other things, payment default, covenant default, breach of representation or warranty, bankruptcy, cross-default, material ERISA events, material money judgments, and failure to maintain subsidiary guarantees. If an event of default occurs, the Agent will be entitled to take various actions, including the acceleration of amounts due under the Credit Agreement, termination of the credit facility, and all other actions permitted to be taken by a secured creditor.

On February 25, 2026, we entered into an amendment to the Credit Agreement. The February 25, 2026, amendment lowered the amount of total allowable borrowings under the revolving credit facility to $275,000 from $350,000 and reduced our minimum consolidated interest coverage ratio to 2.75 to 1.00, through the fourth quarter of 2026. The February 25, 2026, amendment also increased our maximum consolidated leverage ratio to 5.25 to 1.00 for the first and second quarter of 2026, 5.00 to 1.00 for the third quarter of 2026, 4.00 to 1.00 for the fourth quarter of 2026 and 3.50 to 1.00 for 2027 and thereafter. As a result of these financial covenant changes, the interest pricing grid now includes additional interest rate tiers. All other material terms of the Credit Agreement remained unchanged.

Capital Requirements and Sources of Liquidity

During the twelve months ended December 31, 2025 and 2024, our capital expenditures were $11,648 and $12,098 respectively. The decrease of $450 was driven by the Company’s focus on leveraging recent investments and controlling spend during 2025. Capital expenditures for the full year 2026 are expected to be between $15,000 and $20,000.

We have historically relied upon cash available through credit facilities, in addition to cash from operations, to finance our working capital requirements and to support our growth. At December 31, 2025, we had availability of $17,730 through our revolving credit facility. We regularly monitor potential capital sources, including equity and debt financings, in an effort to meet our planned capital expenditures and liquidity requirements. Our future success will be highly dependent on our ability to access outside sources of capital. We will continue to have access to the availability currently provided under the Credit Agreement as long as we remain compliant with the financial covenants. Based on our estimates at this time, we expect to be in compliance with these financials covenants through 2026 and the foreseeable future.

We believe that our operating cash flow and available borrowings under the Credit Agreement are sufficient to fund our operations for 2026 and beyond. However, future cash flows are subject to a number of variables, and additional capital expenditures will be required to conduct our operations. There can be no assurance that operations and other capital resources will provide cash in sufficient amounts to maintain planned or future levels of capital expenditures. In the event we make one or more acquisitions and the amount of capital required is greater than the amount we have available for acquisitions at that time, we could be required to reduce the expected level of capital expenditures and/or seek additional capital. If we seek additional capital, we may do so through borrowings under the Credit Agreement, joint ventures, asset sales, offerings of debt or equity securities or other means. We cannot guarantee that this additional capital will be available on acceptable terms or at all. If we are unable to obtain the funds we need, we may not be able to complete acquisitions that may be favorable to us or finance the capital expenditures necessary to conduct our operations.

Contractual Obligations

The following table presents our obligations and commitments to make future payments under contracts and contingent commitments at December 31, 2025:

Item 7A. Quantitative and Qualitative Disclosures About Market Risk.

We are exposed to market risk from changes in customer forecasts, interest rates, and, to a lesser extent, commodities. To reduce such risks, we selectively use financial instruments and other proactive management techniques.

Table of Contents

Customer Forecasts

The use and consumption of our components, products and services fluctuates depending on order forecasts we receive from our customers. These order forecasts can change dramatically from quarter-to-quarter dependent upon the respective markets that our customers provide products in.

Interest Rate Risk

We are exposed to interest rate risk on certain of our short- and long-term debt obligations used to finance our operations and acquisitions. We have SOFR-based floating rate borrowings under the Credit Agreement, which exposes us to variability in interest payments due to changes in the referenced interest rates.

The amount borrowed under the revolving credit facility under the Credit Agreement was $202.5 million and $79.7 million with an interest rate of 5.98% and 6.55% as of December 31, 2025 and December 31, 2024, respectively. Please see “Liquidity and Capital Resources – Amended and Restated Credit Agreement” in Part II, Item 7 of this Annual Report on Form 10-K and Note 4 – Debt in the Notes to Consolidated Financial Statements for more specifics.

A hypothetical 100-basis-point increase in interest rates would have resulted in an additional $1.4 and $1.1 million of interest expense based on our variable rate debt at December 31, 2025 and December 31, 2024, respectively. We do not use derivative financial instruments to manage interest risk or to speculate on future changes in interest rates. A rise in interest rates could negatively affect our cash flow.

Commodity Risk

We source a wide variety of materials and components from a network of suppliers. Commodity raw materials, such as steel, aluminum, copper, paint and paint chemicals, and other production costs are subject to price fluctuations, which could have a negative impact on our results. We strive to pass along such commodity price increases to customers to avoid profit margin erosion and in many cases utilize contracts with those customers to mitigate the impact of commodity raw material price fluctuations. As of December 31, 2025, we did not have any commodity hedging instruments in place.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Mayville Engineering Company, Inc. and subsidiaries (the "Company") as of December 31, 2025 and 2024, the related consolidated statements of comprehensive income (loss), shareholders’ equity, and cash flows for each of the three years in the period ended December 31, 2025, and the related notes (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2025 and 2024, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2025, in conformity with accounting principles generally accepted in the United States of America.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated March 4, 2026, expressed an unqualified opinion on the Company's internal control over financial reporting.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matters

Table of Contents

Inventory – Refer to Notes 1 and 3 to the financial statements

Critical Audit Matter Description

As of December 31, 2025, the Company holds inventory across a large number of manufacturing facilities dispersed throughout the United States. Inventories are primarily comprised of raw materials, work-in-process, and finished goods that are physically located at the Company's facilities. The Company’s processes to track and determine consolidated inventory relies on a perpetual inventory system that varies by facility based in part upon the information technology (IT) system relevant to the facility.

Auditing the existence of inventory requires significant effort, the involvement of IT specialists due to the integration of IT systems that track physical inventory quantities by facility, and auditor judgment in testing due to the disaggregation of inventory across the facilities and the processes and controls in place. Our auditor judgment includes assessing whether we have obtained sufficient audit evidence, including determining the number of facilities to visit.

How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to the existence of inventory included the following, among others:

●

We involved senior members of the engagement team to determine the extent of testing, including the selection of facilities attended and the number of counts performed.

●

With the assistance of our IT specialists, we tested the effectiveness of controls over management’s process to account for the physical existence of inventory, which included general IT, automated, and manual business process controls.

●

As part of our testing of the effectiveness of controls over inventory, we observed management’s count procedures at selected facilities and obtained and evaluated management’s documentation of counts at other facilities.

●

As part of our year-end audit procedures, we performed independent counts of inventory, on a sample basis at selected facilities, and evaluated any differences in the context of the inventory account balance taken as a whole.

Acquisition — Accu-Fab, LLC — Valuation of Customer Relationships — Refer to Note 2 to the financial statements

Critical Audit Matter Description

On July 1, 2025, the Company acquired 100% of the membership interests of Accu-Fab, LLC (“Accu-Fab”). The Company accounted for the acquisition using the acquisition method of accounting. Accordingly, the purchase price was allocated to the assets acquired and liabilities assumed based on their respective fair values, including the customer relationships intangible asset of $67.0 million. Management estimated the fair value of the customer relationships utilizing the multi-period excess earnings method (MPEEM). The fair value determination of the intangible assets required management to make significant estimates and assumptions, including the discount rate, customer attrition rate, and the determination of future cash flows including revenue growth rates and EBITDA margins.

We identified the valuation and recording of the customer relationships intangible asset as a critical audit matter because of the significant estimates and assumptions management makes to determine the fair value this asset. This required a high degree of auditor judgment and an increased extent of effort, including the need to involve our internal fair value specialists.

How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to the selection of the discount rate and attrition rate, and the determination of future cash flows including revenue growth rates and EBITDA margins, included the following, among others:

●

We tested the effectiveness of controls over the valuation of the customer relationship, including management's controls over the selection of the discount rate and attrition rate, and the determination of future cash flows including revenue growth rates and EBITDA margins.

●

We assessed the reasonableness of management’s forecasts by comparing the projections to historical results and industry data.

●

We tested the accuracy and completeness of underlying customer attrition data used by management.

Table of Contents

●

We involved valuation professionals with specialized skills and knowledge who:

o

Evaluated the discount rate, including testing the underlying market-based source information and the mathematical accuracy of the calculations, and developing a range of independent valuation assumptions and comparing those to the discount rate selected by management.

o

Evaluated the estimated customer attrition rate, including testing the mathematical accuracy of the calculations, comparing the selected attrition rate against relevant historical customer attrition data, and developing a range of attrition rates and comparing those to the attrition rate selected by management.

Report of Independent Registered Public Accounting Firm

To the shareholders and the Board of Directors of Mayville Engineering Company, Inc.

Opinion on Internal Control over Financial Reporting

We have audited the internal control over financial reporting of Mayville Engineering Company, Inc and subsidiaries (the “Company”) as of December 31, 2025, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control — Integrated Framework (2013) issued by COSO.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated financial statements as of and for the year ended December 31, 2025, of the Company and our report dated March 4, 2026, expressed an unqualified opinion on those financial statements.

As described in Management’s Report on Internal Control over Financial Reporting, management excluded from its assessment the internal control over financial reporting at Accu-Fab, LLC (“Accu-Fab”), which was acquired on July 1, 2025, and whose financial statements constitute 2% and 3% of the net and total assets (excluding acquired goodwill and intangibles which were included in management’s assessment of internal control over financial reporting as of December 31, 2025) respectively, and 7% of net sales of the Company’s consolidated financial statement amounts as of and for the year ended December 31, 2025. Accordingly, our audit did not include the internal control over financial reporting at Accu-Fab.

Basis for Opinion

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

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

Definition and Limitations of Internal Control over Financial Reporting

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

Table of Contents

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

Notes to Consolidated Financial Statements

(in thousands, except share amounts and per share data)

Note 1. Nature of business and summary of significant accounting policies

Mayville Engineering Company, Inc. (MEC) is a leading U.S.-based, vertically-integrated, value-added manufacturing partner providing a full suite of manufacturing solutions from concept to production, including design, prototyping and tooling, fabrication, aluminum extrusion, coating, assembly and aftermarket components. Our customers operate in diverse end markets, including heavy- and medium-duty commercial vehicles, construction & access equipment, powersports, data center & critical power, agriculture, military and other end markets. Founded in 1945 and headquartered in Milwaukee, Wisconsin, we are a leading Tier I U.S. supplier of highly engineered components to original equipment manufacturer (OEM) customers with leading positions in their respective markets. The Company maintains 27 facilities, of which 25 are in operation, located in Arkansas, Illinois, North Carolina, Michigan, Mississippi, Ohio, Pennsylvania, Virginia, and Wisconsin. Our engineering expertise and technical know-how allow us to add value through every product redevelopment cycle.

Basis of presentation and consolidation

The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP). They include the accounts of the Company and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.

Use of estimates

Cash and cash equivalents

The Company considers all highly-liquid investments purchased with original maturities of 90 days or less to be cash and cash equivalents.

Concentration of credit risk

Financial instruments that potentially subject the Company to credit risk consist principally of bank balances above the Federal Deposit Insurance Corporation insurability limits of $250 per official custodian. The Company has not experienced any losses on these accounts and management believes the Company is not exposed to any significant credit risk on cash.

Accounts receivable

Accounts receivable are generally uncollateralized customer obligations due under normal trade terms requiring payment within 30 to 60 days from the invoice date. Management periodically reviews past due balances and established an allowance for doubtful accounts of $577 and $248 as of December 31, 2025 and 2024, respectively, for probable uncollectible amounts based on its assessment of the current status of individual accounts. The estimated valuation allowance results in a reduction to sales and the accounts are written-off through a charge to the valuation allowance and a credit to accounts receivable after the Company has used all reasonable collection efforts.

As the Company's customer base is principally made up of blue-chip OEMs with high credit ratings and our trade receivables are due within one year or less, the Company does not have a reserve for credit losses.

Table of Contents

Inventories

Inventories are stated at the lower of cost, determined on the first-in, first-out method (FIFO), or net realizable value. Net realizable value is the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. Work-in-process and finished goods are valued at production cost consisting of material, labor and overhead. The Company maintains a reserve for obsolete and slow-moving inventory of $2,572 and $2,307 as of December 31, 2025 and 2024, respectively, which is based upon the aging of current inventory as well as assumptions on future demand and market conditions.

Tooling in progress

The Company has agreements with its customers to provide production tooling which will be used to produce specific parts for its customers. The costs to design, engineer, and manufacture the tooling are charged to tooling in progress as incurred and based on when control of the tooling is transferred to the customer under contract or when the customer signs off through the Product Part Approval Process (PPAP) or other documented customer acceptance, at a point in time. The Company may also provide production tooling that is not sold to customers but is capitalized in property, plant and equipment. To the extent that estimated costs exceed expected reimbursement from the customer, the Company recognizes a loss. Tooling in progress was $4,746 and $4,761 as of December 31, 2025 and 2024, respectively.

Property, plant and equipment

Property, plant and equipment are stated at cost. Expenditures for additions and improvements are capitalized while replacements, maintenance and repairs which do not improve or extend the lives of the respective assets are expensed as incurred. Properties sold, or otherwise disposed of, are removed from the property accounts, with gains or losses on disposal credited or charged to the results of operations. Depreciation is recognized over the estimated useful lives of the respective assets, using the straight-line depreciation method for financial reporting purposes and begins when the asset is placed into service.

Leases

The Company’s operating leases represent leases of real property, vehicles, and equipment. The Company’s finance leases represent leases for vehicles and equipment. A right-of-use (ROU) asset and a corresponding lease liability are recognized at commencement for contracts that are, or contain, a lease with an original term greater than 12 months. The Company has not elected to recognize right-of-use assets or lease liabilities for leases with a term of twelve months or less. See Note 5 – Leases in the Notes to Consolidated Financial Statements for additional information.

Business combinations

The Company accounts for business combinations in accordance with Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) 805, Business Combinations. In connection with a business combination, the acquiring company must allocate the cost of the acquisition to assets acquired and liabilities assumed based on fair values as of the acquisition date. Any excess or shortage of amounts assigned to assets and liabilities over or under the purchase price is recorded as goodwill or a gain on bargain purchase price, respectively. Transaction costs associated with acquisitions are expensed as incurred within selling, general and administrative expenses.

Goodwill

We test goodwill for impairment annually, or more frequently if triggering events occur indicating that there may be an impairment. We have recorded goodwill and perform testing for potential goodwill impairment at a reporting unit level. A reporting unit is an operating segment, or a business unit one level below an operating segment for which discrete financial information is available, and for which management regularly reviews the operating results. Additionally, components within an operating segment can be aggregated as a single reporting unit if they have similar economic characteristics. We have concluded we have one reporting unit.

Table of Contents

We determine the fair value of our reporting unit using an income approach. Under the income approach, we calculate the fair value of the reporting unit based on the present value of estimated future cash flows. The income approach is dependent on several key management assumptions, including estimates of future sales, gross margins, operating costs, interest expense, income tax rates, capital expenditures, changes in working capital requirements and the weighted average cost of capital or the discount rate. Discount rate assumptions include an assessment of the risk inherent in the future cash flows of the reporting unit. Expected cash flows used under the income approach are developed in conjunction with our budgeting and forecasting process.

We test our goodwill for impairment on an annual basis in the fourth quarter of each fiscal year, and more frequently if events or changes in circumstances indicate that it might be impaired. At December 31, 2025 and 2024, the Company had goodwill with a balance of $140,246 and $92,650, respectively, with the fair value of our reporting unit substantially exceeding the carrying value.

If the market valuation of our common shares or operating results of our reporting unit significantly decline beyond current levels, we may again need to conduct an evaluation of the fair value of our goodwill, which may result in an impairment change.

Changes to management assumptions and estimates utilized in the income approach could negatively impact the fair value conclusions for our reporting units resulting in goodwill impairment. All key assumptions and valuations are determined by and are the responsibility of management. The factors used in the impairment analysis are inherently subject to uncertainty. We believe that the estimates and assumptions are reasonable to determine the fair value of our reporting unit, however, if actual results are not consistent with these estimates and assumptions, goodwill and other intangible assets may be overstated which could result in an impairment charge.

Intangible assets, net

The Company’s primary other intangible assets are customer relationships and contracts, trade names, non-compete agreements, developed technology and patents acquired in business combinations. Intangible assets are initially valued using a methodology commensurate with the intended use of the asset. The costs of amortizable intangible assets are recognized over their expected useful lives using the straight-line method. Intangible assets that are subject to amortization are evaluated for impairment using the same process that is used to evaluate long-lived assets described below. Intangible assets not subject to amortization are assessed for impairment at least annually in the fourth quarter of each fiscal year and whenever events or changes in circumstances indicate that it is more likely than not that an asset may be impaired. The impairment test for indefinite-lived intangible assets consists of a comparison of the fair value of the intangible asset with its carrying amount. An impairment loss is recognized for the amount by which the carrying value exceeds the fair value of the asset.

Fair value of financial instruments

Financial instruments consist of cash and cash equivalents, accounts receivable, accounts payable and long-term debt. The carrying amount of all significant financial instruments approximates fair value due to either the short maturity or the existence of variable interest rates that approximate prevailing market rates. Cash and cash equivalents, accounts receivable and accounts payable are classified as Level 1 fair value inputs as further described in Note 13 – Fair Value of Financial Instruments. Long-term debt is classified as a Level 2 fair value input.

Impairment of long-lived assets

When events or conditions warrant, the Company evaluates the recoverability of long-lived assets and considers whether these assets are impaired. The Company assesses the recoverability of these assets based on several factors, including management’s intention with respect to these assets and their projected undiscounted cash flows. If projected undiscounted cash flows are less than the carrying amount of the respective assets, the Company adjusts the carrying amounts of such assets to their estimated fair value. To the extent that the carrying value of the net assets of an asset group is greater than the estimated fair value, the Company may be required to record impairment charges. The Company records intangible asset impairment charges as a reduction to intangible assets. The Company records other long-lived asset impairment charges as a reduction to property, plant and equipment or a reduction to ROU asset in the Consolidated Balance Sheets.

Table of Contents

Deferred financing costs

Loan issuance costs and discounts are capitalized upon the issuance of long-term debt and amortized over the life of the related debt. Loan issuance costs associated with revolving debt arrangements are presented as a component of other assets. Loan issuance costs incurred in connection with revolving debt arrangements are amortized using the straight-line method over the life of the credit agreement. Loan issuance costs and discounts incurred in connection with term debt are amortized using the effective interest method. Amortization of deferred loan issuance costs and discounts are included in interest expense.

During 2025 and 2024, the Company recorded deferred financing costs associated with its long-term debt and line of credit of $818 and $0, respectively. Amortization expense associated with the deferred debt issuance costs and discounts in 2025, 2024 and 2023 was $271, $282 and $309, respectively. Accumulated amortization was $842 and $423 as of December 31, 2025 and 2024, respectively. Amendments made to existing debt in 2023 resulted in the write-off of $216 in unamortized costs associated with the debt that was replaced during the twelve months ended December 31, 2023.

Revenue recognition

The Company recognizes revenue when control of the goods or services are transferred to a customer in an amount that reflects the consideration it expects to be entitled to in exchange for those goods or services. The Company enters into supply agreements and purchase orders that include both free on board (FOB) origin and FOB destination shipping terms. Depending on the terms of the agreement, the customer takes ownership at shipment or at delivery, and this is when control transfers. Sales are supported by documentation such as supply agreements and purchase orders, which specify certain terms and conditions including product specifications, quantities, fixed prices, delivery dates and payments terms. Revenue related to services is recognized in the period services are performed, thus the Company recognizes revenue at a point in time.

There are many customers where the Company designs, engineers and builds production tooling, which is purchased by the customer. Tooling revenue is recognized at the point the customer signs off on the product through PPAP or other documented customer acceptance and control of the tooling promised under a contract is transferred to the customer at a point in time. Revenue is recognized in an amount that reflects the consideration to which the Company expects to be entitled in exchange for the tooling.

The Company offers certain customers discounts for early payments. These discounts are recorded against net sales in the Consolidated Statement of Comprehensive Income and accounts receivable in the Consolidated Balance Sheets. The Company does not offer any other customer incentives, rebates or allowances.

Shipping and handling

The shipping and handling costs incurred by the Company are included in cost of sales on the Consolidated Statements of Comprehensive Income. These costs are generally comprised of salaries and wages, shipping supplies and warehouse costs. Inbound freight costs, which mostly relate to raw materials, are included in cost of sales on the Consolidated Statements of Comprehensive Income. Outbound freight costs, which mostly relate to sales, are included in net sales on the Consolidated Statements of Comprehensive Income. The Company does not charge customers nor recognize revenue for shipping and handling. The Company’s OEM customers arrange and pay the freight for delivery.

Advertising

The Company expenses the costs of advertising when incurred. Advertising expense was $87, $105 and $141 for the twelve months ended December 31, 2025, 2024 and 2023, respectively. Advertising costs are charged to selling, general and administrative expenses.

Income taxes

Income taxes and uncertain tax positions are accounted for in accordance with ASC 740, Accounting for Income Taxes. Deferred income taxes are provided for the differences between the bases of assets and liabilities for financial reporting and income tax purposes. The Company measures deferred tax assets and liabilities using enacted tax rates in effect for the years in which the differences are expected to reverse and recognizes the effect of a change in enacted rates in the period of enactment. Tax positions

Table of Contents

meeting the more-likely-than-not recognition threshold are measured pursuant to the guidance set forth in ASC 740. A valuation allowance is established when necessary to reduce deferred tax assets to the amount expected to be realized. See Note 8 – Income Taxes of these Notes to Consolidated Financial Statements for further discussion.

Earnings per share

The Company computes basic earnings per share by dividing net income available to shareholders by the actual weighted average number of common shares outstanding for the reporting period. The dilutive impact to basic earnings per share considers the impact to earnings if all convertible securities were exercised or outstanding that do not have an antidilutive impact on earnings per share.

Treasury stock

Treasury stock purchases are accounted for under the cost method whereby the entire cost of the acquired stock is recorded as treasury stock. Subsequent reissuance of shares to the 401(k) Plan or ESOP are recorded as a reduction to treasury stock and as ESOP expense in the Consolidated Statements of Comprehensive Income.

Recently adopted accounting pronouncements

In December 2023, the FASB issued Accounting Standards Update (ASU) 2023-09, Improvements to Income Tax Disclosures, amending ASC 740, Income Taxes. The amendment is intended to enhance the transparency about income tax information through improvements to income tax disclosures primarily related to the rate reconciliation and income taxes paid information. The amendments require that on an annual basis, entities disclose specific categories in the rate reconciliation and provide additional information for reconciling items that meet a quantitative threshold. In addition, the amendments require that entities disclose additional information about income taxes paid as well as additional disclosures of pretax income and income tax expense and remove the requirement to disclose certain items that are no longer considered cost beneficial or relevant. ASU 2023-09 is effective for fiscal years beginning after December 15, 2024, with early adoption permitted. The Company adopted this standard in the fourth quarter of 2025 and the amendments have been applied on a retrospective basis. Adoption of ASU 2023-09 did not have a material impact on the Company’s consolidated financial statements.

Recently issued accounting standards not yet adopted

In November 2024, the FASB issued ASU 2024-03, Expense Disaggregation Disclosures, amending ASC 220, Income Statement – Reporting Comprehensive Income. The amendment requires an entity to provide a disclosure within the financial statement footnotes showing the disaggregation of certain expenses included in relevant expense captions on the consolidated income statement, with a qualitative description of the amounts that are not separately disaggregated quantitatively. The guidance also requires disclosure of the total amount of selling expenses and, in annual reporting periods, an entity’s definition of selling expenses. ASU 2024-03 is effective for fiscal years beginning after December 15, 2026 and for interim periods beginning after December 15, 2027. The guidance is applied on a prospective basis, with a retrospective option and allows for early adoption. The Company is evaluating the potential impact of this guidance on the consolidated financial statements.

In September 2025, the FASB issued ASU 2025-06, Intangibles – Goodwill and Other-Internal-Use Software, amending ASC 350. The amendment removes all references to prescriptive and sequential software development stages. In addition, the amendment also requires consideration whether there is significant uncertainty associated with the development activities of the software during evaluation of probable-to-complete recognition threshold. ASU 2025-06 is effective for interim and annual periods beginning after December 15, 2027. Entities may adopt the guidance using either a prospective approach (including a modified transition approach) or retrospective approach. Early adoption is permitted. The Company has early adopted ASU 2025-06 on a prospective basis, as of January 1, 2026. The adoption of the ASU is not expected to have a material impact on the Company’s consolidated financial statements.

In December 2025, the FASB issued ASU 2025-11, Interim Reporting - Narrow-Scope Improvements, amending ASC 270. The ASU clarifies interim disclosure requirements and the applicability of ASC 270. The objective of the amendments is to provide further clarity about the current interim disclosure requirements. The ASU is effective for interim reporting periods within annual reporting

Table of Contents

periods beginning after December 15, 2027. Adoption of this ASU can be applied either a prospective or a retrospective approach. Early adoption is permitted. The Company is evaluating the potential impact of this guidance on the consolidated financial statements.

In December 2025, the FASB issued ASU 2025-12, Codification Improvements. The ASU addresses thirty-three items, representing the changes to the Codification that (1) clarify, (2) correct errors, or (3) make minor improvements. Generally, the amendments in this Update are not intended to result in significant changes for most entities. The ASU is effective for interim reporting periods within annual reporting periods beginning after December 15, 2026. Early adoption is permitted. The Company is evaluating the potential impact of this guidance on the consolidated financial statements.

Note 2. Acquisitions

On July 1, 2025, the Company acquired 100% of the membership interests of Accu-Fab, LLC (Accu-Fab). The acquisition was consummated in accordance with the terms of the Purchase Agreement dated May 23, 2025, among the Company, Accu-Fab, and Tide Rock YieldCo, LLC (the Seller). The purchase price of the acquisition was $140,500, subject to customary adjustments for the amount of cash, indebtedness, net working capital, and certain expenses of Accu-Fab as of the closing. The acquisition of Accu-Fab was structured as a stock purchase for accounting purposes. As of the closing of the acquisition, after taking into account the estimated adjustments, the Company paid the Seller a total net consideration of $141,185. The final working capital settlement, completed during the three months ended December 31, 2025, is described below. The Company financed the acquisition by borrowing under its amended and restated credit agreement, as amended, as described in Note 4 - Debt in the Notes to the Consolidated Financial Statements.

With locations in Wheeling, Illinois and Raleigh, North Carolina, Accu-Fab is a vertically integrated manufacturing partner providing technology driven, cutting edge metal fabrication solutions to large OEMs. Accu-Fab offers value-added services including design, engineering, sheet metal fabrication and integration, and specialized finishing. The acquisition enhances MEC’s strategic position by broadening its customer base and accelerating its entry into the rapidly growing data center & critical power infrastructure end markets.

The Company accounted for the acquisition using the acquisition method of accounting in accordance with ASC 805, Business Combinations, with MEC being the acquiring entity. Transaction costs related to the acquisition were expensed as incurred within other selling, general, and administrative expenses and totaled $3,423 for the twelve months ended December 31, 2025. The net sales and operating income of Accu-Fab, which is consolidated in MEC’s financial statements presented herein, since July 1, 2025 were $40,697 and $7,335, respectively, for the twelve months ended December 31, 2025.

The aggregate purchase price has been allocated to the assets acquired and liabilities assumed based on their preliminary estimated fair values as of the acquisition date. The estimate of the excess purchase price over the preliminary estimated fair value of net tangible assets acquired was allocated to identifiable intangible assets and goodwill. The Company engaged an independent third party to assist with the identification and valuation of the acquired assets, including intangible assets. Management makes significant estimates and assumptions when determining the fair value of assets acquired and liabilities assumed. These estimates include, but are not limited to, discount rates, projected future net sales, projected future expected cash flows, useful lives, attrition rates, and growth rates. These measures are based on significant Level 3 inputs not observable in the market.

Table of Contents

The following table is a summary of the assets acquired, liabilities assumed, and net cash consideration paid for the acquisition of Accu-Fab. The allocation is considered preliminary and subject to finalization within one year from the acquisition date:

Inventory was valued at its estimated fair value, which is defined as expected sales price, less costs to sell, plus a reasonable margin for selling effort. The valuation resulted in an inventory fair value step-up of $591 and was fully expensed and reflected in cost of sales on the Consolidated Statement of Comprehensive Income (Loss) during the twelve months ended December 31, 2025.

Property, plant and equipment was valued at its estimated fair value using the cost, market and sales comparison approaches. The valuation resulted in a property, plant and equipment fair value step-up of $5,326. Depreciation on property, plant and equipment is computed on a straight-line basis over the estimated useful life of the respective assets.

The Company also recorded $67,000 of customer relationships intangible assets with useful lives of fourteen years and $2,200 of non-compete agreement intangible assets with useful lives of two years. The purchase price allocated to these assets was based on management’s forecasted cash inflows and outflows and the multi-period excess earnings method for customer relationships and the with and without method for the non-compete agreements. Amortization expense related to these intangible assets is recorded on a straight-line basis and reflected in amortization of intangible assets on the Consolidated Statements of Comprehensive Income (Loss).

The purchase price of Accu-Fab exceeded the preliminary estimated fair value of identifiable net assets and accordingly, the difference was allocated to goodwill, all of which is tax deductible. Goodwill will be tested for impairment at least annually, or more frequently if events or changes in circumstances indicate that the asset may be impaired, in accordance with ASC 350, Intangibles – Goodwill and Other. The goodwill recognized primarily reflects expected synergies from integrating Accu-Fab’s operations into the Company’s existing manufacturing platform, the assembled workforce, and other intangible assets that do not meet the criteria for separate recognition under ASC 805.

Table of Contents

The Company believes that the information gathered to date provides a reasonable basis for estimating the fair values of assets acquired and liabilities assumed; however, the purchase price allocation remains preliminary as we continue to gather the necessary information to finalize our fair value estimates and provisional amounts. Provisional amounts include items related to working capital adjustments, intangibles, indemnification of assets and liabilities and deferred taxes. During the three months ended December 31, 2025, the Company finalized the net working capital settlement with the Seller, resulting in an adjustment of $108 to the purchase consideration related to working capital adjustments.

The Company has recorded preliminary estimates for the items that remain subject to valuation and will record adjustments, if any, to the preliminary amounts upon finalization of the respective valuations. Such changes are not expected to be significant. The Company expects to complete the purchase price allocation as soon as practicable but no later than one year from the acquisition date.

Pro Forma Financial Information (Unaudited)

In accordance with ASC 805, the following unaudited pro forma combined results of operations have been prepared and presented to give effect to the Accu-Fab acquisition as if it had occurred on January 1, 2024, the beginning of the comparable period, applying certain assumptions and pro forma adjustments. These pro forma adjustments primarily relate to the estimated depreciation expense associated with the fair value of the acquired property, plant and equipment, amortization of identifiable intangible assets, interest expense related to additional debt needed to fund the acquisition and the tax impact of these adjustments. Additionally, the pro forma adjustments exclude non-recurring expenses related to transaction costs, which were expensed as incurred, and include the sale of stepped-up inventory. The unaudited pro forma consolidated results are provided for illustrative purposes only, are not indicative of the Company’s actual consolidated results of operations or consolidated financial position and do not reflect any revenue and operating synergies or cost savings that may result from the acquisition.

Note 4. Debt

On June 28, 2023, and as amended on June 26, 2025, we entered into an amended and restated credit agreement (the Credit Agreement) with certain lenders and Wells Fargo Bank, National Association, as administrative agent (the Agent). The June 26, 2025, amendment increased the amount of total allowable borrowings under the revolving credit facility to $350,000 from $250,000, by exercising the previously available $100,000 accordion feature. All other material terms of the Credit Agreement, including applicable interest rates, remained unchanged. All amounts borrowed under the Credit Agreement mature on June 28, 2028.

The Credit Agreement contains usual and customary negative covenants for agreements of this type, including, but not limited to, restrictions on our ability to, subject to certain exceptions, create, incur or assume indebtedness; create, incur, assume or suffer to exist liens; make certain investments; allow our subsidiaries to merge or consolidate with another entity; make certain asset dispositions; pay certain dividends or other distributions to shareholders; enter into transactions with affiliates; enter into sale leaseback transactions; and exceed the limits on annual capital expenditures. The Credit Agreement also requires us to satisfy certain financial covenants, including a minimum consolidated interest coverage ratio of 3.00 to 1.00 as well as a consolidated total leverage ratio not to exceed 3.50 to 1.00. This ratio increases to 4.00 to 1.00 for the four quarters following an acquisition provided the acquisition meets certain agreed upon terms. The Accu-Fab acquisition on July 1, 2025 met these terms.

The Company incurred financing costs of $818 associated with executing the June 26, 2025, amendment. As of December 31, 2025, short-term and long-term balances of $273 and $409, respectively, were recorded in prepaid expenses and other current assets and other long-term assets in the Consolidated Balance Sheets. These deferred financing costs will be amortized over the remaining duration of the Credit Agreement.

At December 31, 2025, our consolidated total leverage ratio was 3.68 to 1.00 as compared to a covenant maximum of 4.00 to 1.00 under the Credit Agreement.

Table of Contents

At December 31, 2025, our consolidated interest coverage ratio was 5.47 to 1.00 as compared to a covenant minimum of 3.00 to 1.00 under the Credit Agreement.

Under the Credit Agreement, interest is payable quarterly at the adjusted secured overnight financing rate (SOFR) plus an applicable margin based on the current consolidated total leverage ratio (which may be adjusted for certain reserve requirements), plus 1.25% to 2.75% depending on the current consolidated total leverage ratio. Under certain circumstances, we may not be able to pay interest based on SOFR. If that happens, we will be required to pay interest at the Base Rate, which is the sum of the higher of (i) the Prime Rate (as publicly announced by the Agent from time to time), (ii) the Federal Funds Rate plus 0.50%, and (iii) Adjusted Term SOFR for a one-month tenor in effect on such day plus 1.00%. The interest rate was 5.98% and 6.55% as of December 31, 2025 and December 31, 2024, respectively. Additionally, the agreement has a fee on the average daily unused portion of the aggregate unused revolving commitments. This fee was 0.30% and 0.25% as of December 31, 2025 and December 31, 2024, respectively.

The Company was in compliance with all financial covenants of its credit agreements as of December 31, 2025 and December 31, 2024. The amount borrowed on the revolving credit notes was $202,525 and $79,725 as of December 31, 2025 and December 31, 2024, respectively.

Other Debt

Additionally, the Company has a Fond du Lac County and Fond du Lac Economic Development Corporation term note (Fond du Lac Term Note). The Fond du Lac Term Note is secured by a security agreement, payable in annual installments of $500 plus interest at 2.00% and is due in full in December 2028. The balance outstanding as of December 31, 2025 and December 31, 2024 was $1,375 and $1,875, respectively. As of December 31, 2025, the short-term and long-term balance of $500 and $875, respectively. As of December 31, 2024, the short-term and long-term balance was $500 and $1,375, respectively. These balances are recorded in other current liabilities and other long-term liabilities in the Consolidated Balance Sheets.

Note 5. Leases

The Company has real property operating leases for office and manufacturing space. Operating leases for the Company’s personal property consist of leases for office equipment, vehicles, forklifts and storage tanks for bulk gases. The Company recognizes a right-of-use (ROU) asset and a lease liability for operating leases based on the net present value of future minimum lease payments. Lease expense for the Company’s operating leases is recognized on a straight-line basis over the lease term, including renewal periods that are considered reasonably certain. The Company has not elected to recognize right-of-use assets or lease liabilities for leases with a term of twelve months or less.

The Company has finance leases for equipment used throughout its office and manufacturing facilities along with vehicles used by employees. The Company recognizes an ROU asset and a lease liability for finance leases based on the net present value of future minimum lease payments. Lease expense for the Company’s finance leases is comprised of the amortization of the ROU asset and interest expense recognized based on the effective interest method.

Variable lease expense is related to certain of the Company’s real property leases and personal property leases, and it generally consists of property tax and insurance components that are for the benefit of the lessor (real property leases) and variable overage fees (personal property leases) that are remitted as part of the Company’s lease payments.
