RISK FACTORS

Investing in our common stock involves a high degree of risk. You should carefully consider the risks and uncertainties described below, together with all of the other information in this prospectus, 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

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:

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 ability 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.

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

We derive a large amount of our net sales from customers in the following industry sectors: heavy- and medium-duty commercial vehicles, construction, powersports, agriculture and military. Factors affecting any of these

20

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:

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.

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:

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 majority of our net sales. For example, our largest customers in 2018, including John Deere, AB Volvo, Honda Motor Co. and PACCAR Inc. accounted for 17%, 14%, 12% and 12% of our pro forma 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

21

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:

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:

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. Such investments may lead to low utilization levels if customer 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 have failed to materialize and delivery schedules have been deferred as a result of changes in our customers’ business needs.

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. Accordingly,

22

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 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.

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; and (v) not receiving required regulatory approvals or such approvals being delayed or restrictively conditional. 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.

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

23

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

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 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 have been instrumental in our growth and development. In addition, in order to manage our growth, we will 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. If our employees are under-utilized, our profitability could suffer.

We are dependent on information technology and our systems and infrastructure face certain risks, including cyber security 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, 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.

24

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 or other natural disasters 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. Additionally, 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.

Political and economic developments could adversely affect our business.

Increased political instability and social unrest, evidenced by the threat or occurrence of terrorist attacks, enhanced national security measures 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.

Volatility in the prices or availability 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 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. 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.

25

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.

The impact of foreign trade relations and associated tariffs 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, could 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. 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.

Additionally, our customers’ businesses may be 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 could, in turn, reduce our customers’ demand for the components that we manufacture for them. Any reduction in customer demand for our components as a result such tariffs, taxes, customs duties and/or other trade regulations could have a material adverse impact on our financial position, results of operations, cash flows and liquidity.

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 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.

26

We may need to raise additional capital in the future for working capital, capital expenditures and/or acquisitions, and we may not be able to do so on favorable terms, or at all, which would impair our ability to operate our business or achieve our growth objectives.

Our ongoing ability to generate cash is important for the funding of our continuing operations, making acquisitions and servicing our indebtedness. To the extent that existing cash balances and cash flow from operations, together with borrowing capacity under our existing credit facilities, are insufficient to make investments or acquisitions or provide needed working capital, we may require additional financing from other sources. Our ability to obtain such additional financing in the future will depend in part upon prevailing capital market conditions, as well as conditions in our business and our operating results, and those factors may affect our efforts to arrange additional financing on terms that are acceptable to us. Furthermore, if economic, political or other market conditions adversely affect the financial institutions that provide credit to us, it is possible that our ability to draw upon our existing credit facilities may be impacted. If adequate funds are not available, or are not available on acceptable terms, we may not be able to make future investments, take advantage of acquisitions or other opportunities, or respond to competitive challenges, resulting in loss of market share, any of which could have a material adverse impact on our financial position, results of operations, cash flows and liquidity.

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. 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 growing concerns about climate change. In recent years, federal, state and local governments have taken steps to reduce emissions of greenhouse gases, or 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. While the current administration has announced that the United States will withdraw from international commitments to reduce GHG emissions, many state and local officials have announced their decisions to uphold such commitments.

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

27

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 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. 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 businesses 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

28

indemnification was not available could have a material adverse effect on our business, results of operations and/or financial condition.

We may experience work-related accidents that may expose us to liability claims.

Due to the nature of our operations, we are subject to the risks of our employees being exposed to industrial-related accidents at our premises. If such accidents occur in the future, we may be required to pay compensation and may also suffer reputational harm. Under such circumstances, our business and financial performance could be adversely affected.

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 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. Pursuant to the Affordable Care Act, employees may be ineligible for certain healthcare subsidies if such employee is eligible and offered qualifying and affordable healthcare coverage under an employer’s plan. Due to the breadth and complexity of the healthcare reform legislation, the lack of implementing regulations and interpretive guidance 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.

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.

Prior to this offering, we were treated as an S Corporation, and claims of taxing authorities related to our prior status as an S Corporation could have an adverse effect on our business, financial condition and results of operations.

Upon the consummation of this offering, our status as an S Corporation will terminate and we will be treated as a “C Corporation” for U.S. federal income tax purposes and thus will begin to be subject to U.S. federal income tax. If the unaudited, open tax years in which we were an S Corporation are audited by the Internal Revenue Service, or IRS, and we are determined not to have qualified for, or to have violated any requirement for maintaining, our S Corporation status, we will be obligated to pay back taxes, interest and possibly penalties. The amounts that we would be obligated to pay could include taxes on all our taxable income attributable to such open tax years. Any such claims could result in additional costs to us and could have a material adverse effect on our business, financial condition and results of operations.

29

Prior to the completion of this offering we are 100% owned by the 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 Code and ERISA. The ESOP has received a determination letter from the 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. Additionally, any retroactive loss of the ESOP’s tax-qualified status would adversely impact our prior treatment as an S Corporation. See “—Prior to this offering, we were treated as an S Corporation, and claims of taxing authorities related to our prior status as an S Corporation could have an adverse effect on our business, financial condition and results of operations.”

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.

Risks Related to Our Indebtedness

Our Credit Agreements restrict our ability and the ability of our subsidiaries to engage in some business and financial transactions.

On December 14, 2018, we entered into a credit agreement with certain lenders and Wells Fargo Bank, National Association, as administrative agent, which we sometimes refer to as the Senior Credit Agreement. The Senior Credit Agreement provides for (i) a $90.0 million revolving credit facility, with a letter of credit sub-facility in an aggregate amount not to exceed $5.0 million, and a swingline facility in an aggregate amount of $15.0 million, which we sometimes collectively refer to as the Revolving Loan, and (ii) a $69.0 million term loan facility, which we sometimes refer to as Term Loan A, and a $26.0 million real estate term loan facility, which we sometimes refer to as the Real Estate Term Loan, and, together with Term Loan A, which we sometimes collectively refer to as the Term Loans.

On December 14, 2018, we also entered into a credit agreement with certain lenders and Wells Fargo Strategic Capital Inc., as administrative agent, which we sometimes refer to as the Subordinated Credit Agreement and, together with the Senior Credit Agreement, as the Credit Agreements. The Subordinated Credit Agreement provides for a $25.0 million term loan facility, which we sometimes refer to as the Subordinated Term Loan.

30

Our Credit Agreements contain a number of covenants that limit our ability and the ability of our subsidiaries to:

Each Credit Agreement also requires us to maintain a fixed charge coverage ratio and a consolidated 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, certain changes of control, material money judgments and failure to maintain subsidiary guarantees). If an event of default occurs under either Credit Agreement, the lenders under such 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 either Credit Agreement may result in an event of default under such 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.

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

At December 31, 2018, we had $95.0 million outstanding under the Term Loans, $59.6 million outstanding under the Revolving Loan and $25.0 million outstanding under the Subordinated Term Loan. 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 each of the Credit Agreements 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 Our Common Stock and This Offering

Your ability to influence corporate matters may be limited because the ESOP owns a substantial amount of our stock and will continue to have significant influence over us after this offering, which may limit your ability to influence the outcome of important transactions, including a change in control.

Upon completion of this offering, our employees and certain former employees, through their interests in the 401(k) ESOP and the Traditional ESOP, will beneficially own approximately 68.26% of the outstanding shares of our common stock. Following completion of this offering, each ESOP participant is entitled to direct the vote of the shares allocated to his or her ESOP account, in his or her sole discretion. As a result, our employees and former employees, if acting together, will be able to influence or control 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 participants’ interests may be contrary to yours. This concentration of ownership may have the effect of delaying, preventing or deterring a change in control of our company, could deprive our non-ESOP 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 ESOP Trustee may have the power to vote in its discretion a large block of shares on matters presented to shareholders for approval.

Following completion of this offering, ESOP participants have the right to direct the vote of the shares allocated to his or her ESOP account. However, if a participant does not timely direct the voting of his or her shares, then the ESOP Trustee will vote such shares in its independent fiduciary discretion. Additionally, the ESOP Trustee has fiduciary duties under ERISA which may cause the ESOP Trustee to override participants’ voting directions. Consequently, there may be circumstances in which the ESOP Trustee has the ability to vote a significant block of shares on matters presented to shareholders for approval. The ESOP, which as a retirement plan has the purpose of providing retirement benefits to current and former employees of the company and their beneficiaries, may have interests that are different from yours and may vote in a way with which you disagree and which may be adverse to your interests.

There is no existing market for our common stock and an active, liquid trading market for our common stock may not develop following this offering.

Prior to this offering, there has been no public market for our common stock. We cannot predict the extent to which investor interest in our company will lead to the development of an active trading market or how liquid that market may become. If an active trading market does not develop, you may have difficulty selling any of our common stock that you purchase. The initial public offering price of our common stock was determined by negotiation between us and the underwriters, and may not be indicative of prices that will prevail after the completion of this offering. In addition, the market price of our common stock may decline below the initial public offering price, and you may not be able to resell your shares at, or above, the initial public offering price.

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

Prior to this offering, there has been no public market for shares of our common stock. The initial public offering price of our common stock will be determined through negotiation between us and the underwriters. This price will not necessarily reflect the price at which investors in the market will be willing to buy and sell shares of our common stock following this offering. In addition, the market price of our common stock following this offering is likely to be highly volatile, may be higher or lower than the initial public offering price and could be subject to wide

32

fluctuations in response to various factors, some of which are beyond our control. These fluctuations could cause you to lose all or part of your investment in our common stock since you might be unable to sell your shares at or above the price you paid in this offering. Factors that could cause fluctuations in the market price of our common stock include the following:

In the past, following periods of volatility in the overall market and the market price of a particular company’s securities, securities class action litigation has often been instituted against these companies. This litigation, if instituted against us, could result in substantial costs and a diversion of our management’s attention and resources.

Additionally, if our common stock is not listed on, or becomes delisted from, the New York Stock Exchange, or NYSE, for any reason, and is quoted on the OTC Bulletin Board, an inter-dealer automated quotation system for equity securities that is not a national securities exchange, the liquidity and price of our securities may be more limited than if we were quoted or listed on the NYSE or another national securities exchange. You may be unable to sell your securities unless a market can be established or sustained.

Sales of outstanding shares of our common stock into the market in the future could cause the market price of our common stock to drop significantly, even if our business is doing well.

Immediately after this offering, we will have outstanding 19,693,484 shares of our common stock. Of these shares, the 6,250,000 shares sold in this offering will be freely tradable except for any shares purchased by our “affiliates” as that term is used in Rule 144 under the Securities Act and any shares sold to our directors or officers pursuant to our directed share program.

Of the remaining outstanding shares approximately 13,443,484 shares of common stock will be held by the ESOP. Additionally, 2,000,000 shares of common stock are reserved for issuance under the Mayville Engineering Company, Inc. 2019 Omnibus Incentive Plan, which we sometimes refer to as the Omnibus Incentive Plan, which we adopted in connection with this offering. We intend to register the shares reserved for issuance under our Omnibus Incentive Plan and the shares subject to diversification rights under the ESOP and applicable law on Form S-8 registration statements following this offering.

33

The 2019 annual diversification election opportunity for participants in the Traditional ESOP (based upon participant share balances as of December 31, 2018) is anticipated to run until at least the 90 ^th day following completion of this offering and the Traditional ESOP will then distribute shares of our common stock that any participants have elected to diversify 90 days following the end of the diversification election period. Therefore, no shares distributed in connection with Traditional ESOP diversification elections will be available for sale prior to 180 days following the date of this offering, but shares will be distributed to electing participants no later than December 31, 2019. Upon completion of this offering, approximately 558,000, or 2.8%, of our shares will be eligible for the 2019 diversification opportunity. There are approximately 150 Traditional ESOP participants that are eligible to diversify in the 2019 diversification period, who have an average balance of 0.019% of our shares after this offering, and none of whom hold more than 0.263% of our shares after this offering. Upon completion of the 2019 diversification opportunity, eligible Traditional ESOP participants’ next opportunity to diversify will occur during the 2020 diversification election period, and annually thereafter.

As required by law, 401(k) ESOP participants who have at least three years of service will be able to elect to sell some or all the shares of our common stock held in their 401(k) ESOP accounts and invest such proceeds in the other investment options made available under the 401(k) ESOP. The initial participant diversification opportunity will take place 180 days after the date of this offering following which the trustee will sell shares on behalf of diversifying participants in an orderly fashion. Therefore, no shares distributed in connection with 401(k) ESOP diversification elections will be available for sale prior to 180 days following the date of this offering. Upon completion of this offering, approximately 2,661,000, or 13.5%, of our shares would be eligible for the initial diversification election under the 401(k) ESOP. There are approximately 2,200 401(k) ESOP participants that are eligible to diversify in the initial diversification opportunity, who have an average balance of 0.006% of our shares after this offering, and none of whom hold more than 0.085% of our shares after this offering.

Upon termination of employment or death, participants are entitled to receive distributions in equal annual installments over a period of five years of the shares of our common stock allocated to such participant’s account under the 401(k) ESOP and the Traditional ESOP. The 2019 annual distribution period for these ex-employees will occur no earlier than 180 days following the date of this offering. Upon completion of this offering, approximately 827,000, or 4.2%, of our shares will be the subject of such a distribution. There are approximately 780 ESOP participants that will receive shares of our common stock in the 2019 distribution, who will receive, on average, 0.004% of our shares after this offering, and none of whom will receive in the 2019 distribution more than 0.119% of our shares after this offering.

Following the time periods set forth above, the terms of the ESOPs may be amended to allow for more frequent sales of our common stock by participants or more frequent distributions to terminated participants.

While our officers and directors and the ESOP itself (subject to certain exceptions) are subject to lock-up agreements, other participants in the ESOP generally are not subject to lock-up agreements. Therefore, participants who fall into one of the three categories described above and who are not locked up will be eligible to sell all their shares in the market after the dates described above without restrictions. We cannot predict whether any participants will exercise their diversification elections or if they do as to how many shares. We cannot predict the effect, if any, that the sales of shares by the participants who make diversification elections or who receive shares following their termination of employment or death may have on the market price of our common stock. Sales of substantial amounts of our common stock by participants may cause the market price of our common stock to decline.

After this offering, we will have an aggregate of 53,306,516 shares of common stock authorized but unissued and not reserved for issuance under our Omnibus Incentive Plan or otherwise. We may issue all of these shares without any action or approval by our shareholders. The issuance of additional shares could be dilutive to existing holders.

34

Investors in this offering will experience immediate and substantial dilution.

The initial public offering price of our common stock will be substantially higher than the pro forma net tangible book value per share of the outstanding common stock immediately after this offering. Based on an assumed initial public offering price of $20.00 per share (the mid-point of the price range set forth on the cover page of this prospectus) and our net tangible book value as of December 31, 2018, if you purchase our common stock in this offering you will pay more for your shares than the amounts paid by our existing shareholders for their shares and you will suffer immediate dilution of approximately $15.17 per share in pro forma net tangible book value. See “Dilution.” As a result of such dilution, investors purchasing common stock in this offering may receive significantly less than the full purchase price that they paid for the shares purchased in this offering in the event of a liquidation.

If securities or industry analysts do not publish or cease publishing research or reports about us, our business, or our market, or if they change their recommendations regarding our securities adversely, the price and trading volume of our securities could decline.

The trading market for our securities will be influenced by the research and reports that industry or securities analysts may publish about us, our business, our market or our competitors. Securities and industry analysts do not currently, and may never, publish research on us. If no securities or industry analysts commence coverage of us, our stock price and trading volume would likely be negatively impacted. If any of the analysts who may cover us change their recommendation regarding our securities adversely, or provide more favorable relative recommendations about our competitors, the price of our securities would likely decline. If any analyst who may cover us were to cease coverage of us or fail to regularly publish reports on it, we could lose visibility in the financial markets, which could cause our stock price or trading volume to decline.

We will have broad discretion over the use of the proceeds to us from this offering, and we may not use these funds in a manner of which you would approve or which would enhance the market price of our common stock.

We will have broad discretion to use the net proceeds from this offering, and you will be relying on the judgment of our board of directors and management regarding the use of these proceeds. We intend to use a significant portion of the net proceeds from this offering to repay existing indebtedness, including indebtedness incurred with respect to the DMP acquisition.

After the completion of this offering, 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, after the completion of this offering, 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 deems 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 amended and restated articles of incorporation and bylaws that will be in effect at the closing of this offering could make a merger, tender offer or proxy contest difficult, thereby depressing the trading price of our common stock.

Upon the closing of this offering, our status as a Wisconsin corporation and the anti-takeover provisions of the Wisconsin Business Corporation Law, which we sometimes refer to as the WBCL, may discourage, delay or

35

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 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 price requirements of the WBCL with respect to form and amount.

In addition, our amended and restated articles of incorporation and bylaws that will be in effect upon the closing of this offering contain provisions that may make the acquisition of the company more difficult, including the following:

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 you and other shareholders to elect directors of your choosing or prevent us from taking other corporate actions that you desire.

Risks Related to Being a Public Company

The requirements of being a public company may strain our resources and distract our management, which could make it difficult to manage our business.

Following the completion of this offering, we will be required to comply with various regulatory and reporting requirements, including those required by the United States Securities and Exchange Commission, or the SEC. Complying with these reporting and other regulatory requirements will be time-consuming and will result in increased costs to us and could have a negative effect on our business, financial condition and operating results.

As a public company, we will be subject to the reporting requirements of the Securities Exchange Act of 1934, as amended, which we sometimes refer to as the Exchange Act, and the requirements of the Sarbanes-Oxley Act of 2002. These requirements may place a strain on our systems and resources. The Exchange Act requires that we file annual, quarterly and current reports with respect to our business and financial condition. The Sarbanes-Oxley Act requires that we maintain effective disclosure controls and procedures and internal controls over financial reporting. To maintain and improve the effectiveness of our disclosure controls and procedures, we may need to commit significant resources, hire additional staff and provide additional management oversight. We will be implementing additional procedures and processes for the purpose of addressing the standards and requirements

36

applicable to public companies. Sustaining our growth also will require us to commit additional management, operational and financial resources to identify new professionals to join the company and to maintain appropriate operational and financial systems to adequately support expansion. These activities may divert management’s attention from other business concerns, which could have a material adverse effect on our business, financial condition and operating results.

We cannot predict or estimate the amount of additional costs we may incur as a result of becoming a public company or the timing of such costs.

We have identified material weaknesses in our internal control over financial reporting. If our remediation of these material weaknesses is not effective, or if we experience additional material weaknesses in the future or otherwise fail to maintain an effective system of internal controls in the future, we may not be able to accurately or timely report our financial condition or results of operations, which may adversely affect investor confidence in us and, as a result, the value of our common stock.

As a public company, we will be required in future years to document and assess the effectiveness of our system of internal controls over financial reporting to satisfy the requirements of the Sarbanes-Oxley Act.

During the course of preparing for this offering, we identified two material weaknesses in the design and operation of our internal control over financial reporting. A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of a company’s annual or interim financial statements will not be prevented or detected on a timely basis. The first material weakness relates to information technology general controls specific to segregation of duties, systems access and change management processes. The second material weakness relates to a lack of consistently documented accounting policies and procedures, a lack of controls over the preparation and review of journal entries and a limited number of personnel with a level of GAAP accounting knowledge commensurate with our financial reporting requirements, which, in the aggregate, constitute a material weakness.

We are currently evaluating a number of steps to enhance our internal control over financial reporting and address these material weaknesses, including: hiring of additional financial reporting personnel with technical accounting and financial reporting experience, enhancing our internal review procedures during the financial statement close process, and designing and implementing IT general computer controls; however, our current efforts to design and implement effective controls may not be sufficient to remediate the material weaknesses described above or prevent future material weaknesses or other deficiencies from occurring. Despite these actions, we may identify additional material weaknesses in our internal control over financial reporting in the future.

If we fail to effectively remediate these material weaknesses in our internal control over financial reporting, if we identify future material weaknesses in our internal control over financial reporting or if we are unable to comply with the demands that will be placed upon us as a public company, including the requirements of Section 404 of the Sarbanes-Oxley Act, in a timely manner, we may be unable to accurately report our financial results, or report them within the timeframes required by the SEC. In addition, if we are unable to assert that our internal control over financial reporting is effective, or if our independent registered public accounting firm is unable to express an opinion as to the effectiveness of our internal control over financial reporting, when required, investors may lose confidence in the accuracy and completeness of our financial reports, we may face restricted access to the capital markets and our stock price may be adversely affected.

Commencing with our second annual report on Form 10-K that we will file after becoming a public reporting company, we must perform system and process evaluation and testing of our internal control over financial reporting to allow management to report on the effectiveness of our internal control over financial reporting in our

37

Form 10-K filing for that year, as required by Section 404 of the Sarbanes Oxley Act. We expect to expend significant resources in developing the necessary documentation and testing procedures required by Section 404. If we fail to implement the requirements of Section 404 in a timely manner, regulatory authorities such as the SEC or the Public Company Accounting Oversight Board, or the PCAOB, might subject us to sanctions or investigation. We cannot be certain that the actions we will be taking to improve our internal controls over financial reporting will be sufficient, or that we will be able to implement our planned processes and procedures in a timely manner.

We are an emerging growth company, and any decision on our part to comply only with certain reduced reporting and disclosure requirements applicable to emerging growth companies could make our common stock less attractive to investors.

We are an “emerging growth company” as defined in the JOBS Act. Under the JOBS Act, emerging growth companies can delay adopting new or revised accounting standards until such time as those standards apply to private companies. We have elected to use this exemption from new or revised accounting standards and, therefore, we will not be subject to the same new or revised accounting standards as other public companies that have not made this election.

For as long as we continue to be an emerging growth company, we also intend to take advantage of certain other exemptions from various reporting requirements that are applicable to other public companies including, but not limited to, reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved. We cannot predict if investors will find our common stock less attractive because we will rely on these exemptions. If some investors find our common stock less attractive as a result, there may be a less active trading market for our common stock and our stock price may be more volatile.

We will remain an emerging growth company until the earliest of (i) the last day of the year in which we have total annual gross revenue of $1.07 billion or more; (ii) the last day of the year following the fifth anniversary of the date of the closing of this offering; (iii) the date on which we have issued more than $1.0 billion in nonconvertible debt during the previous three years; or (iv) the date on which we are deemed to be a large accelerated filer under the rules of the SEC.

Our business and stock price may suffer as a result of our lack of public company operating experience.

We have never operated as a public company, and we expect that the obligations of being a public company, including substantial public reporting, auditing and investor relations obligations, will require significant additional expenditures, place additional demands on our management and require the hiring of additional personnel. These obligations will increase our operating expenses and could divert our management’s attention from our operations. The Sarbanes-Oxley Act and the SEC rules and regulations implementing such Act, as well as various NYSE rules, will require us to implement additional corporate governance practices and may require further changes. These rules and regulations will increase our legal and financial compliance costs, and make some activities more difficult, time-consuming and/or costly. We also expect these rules and regulations to make it more difficult and more expensive for us to obtain director and officer liability insurance. We may be required to accept reduced coverage or incur substantially higher costs to obtain coverage. These rules and regulations could also make it more difficult for us to attract and retain qualified independent members of our board of directors and qualified members of our management team.
