OUR COMPANY

We are a leading component manufacturer and supplier serving original equipment manufacturers (“OEMs”) primarily in the recreational vehicle (“RV”) and manufactured housing (“MH”) markets. We also supply certain products to adjacent industrial (“Industrial”) markets, including the commercial, institutional, and residential furniture and fixtures markets.

We play an important role in the value chain within each of the end markets in which we participate. We offer a broad product portfolio consisting of components that are integral to the overall aesthetics, quality, and function of the finished product sold to the consumer. To deliver a wide variety of components to our customers, we source raw materials and select products, innovate and collaborate on design, product and materials and manufacture or assemble components that are differentiated and aligned with consumer preferences in today’s competitive market. Our success depends on our ability to provide quality products and service through our value added relationships to help our customers satisfy consumer preferences. Our goal is to present them with significant product line depth and breadth allowing them to focus on designing, assembling and marketing the end product.

We serve our customers in the estimated $4 billion currently addressable portion of the RV market, which includes both towable and motorized RVs, the $900 million currently addressable portion of the MH market, and the large and fragmented Industrial markets. Our customers include the largest manufacturers in each of the RV and MH segments as well as distributors, component suppliers, and manufacturers serving the Industrial markets.

We operate through a nationwide network of 56 manufacturing and 22 distribution facilities in 16 states, thereby allowing us to be responsive and close to our customers, while simultaneously reducing in-transit delivery time and cost to the regional manufacturing footprint of our customers. We believe that we are one of the few suppliers to the RV and MH markets that has such an extensive network.

Our strategic and capital allocation strategy is focused on optimally managing and utilizing our resources and leveraging our platform of operating brands to continue to grow our business. Through strategic acquisitions, expansion geographically and into new product lines, investment in infrastructure and capital expenditures, we seek to ensure that our operating network contains the capacity, technology, and innovative thought process necessary to proactively support anticipated growth needs. Additionally, we look to effectively and efficiently respond to changes in market conditions, successfully integrate manufacturing, distribution and administrative functions, and provide capital and operational resources to our acquired companies while still allowing them to maintain an entrepreneurial spirit and, in turn, enabling the continuation of their legacy value proposition to our customer base.

Over the last three years, we have executed on a number of new product initiatives and have invested approximately $351 million to complete 14 acquisitions involving 19 companies, which directly complement our

S-1

Table of Contents

core competencies and existing product lines. Additionally, we introduced over 300 new products and product line extensions through strategic acquisitions and organically in an ongoing effort to bring additional value to customers.

The combination of improving economic conditions and demographic trends benefitting the RV industry and the execution of the strategic initiatives identified above, among others, resulted in increases in our sales, operating income, net income and cash flows for each of the last four years ended December 31, 2016.

As of December 31, 2016, we employed approximately 4,800 employees. Our corporate headquarters are located in Elkhart, Indiana.

OUR VALUE PROPOSITION

We believe our customers value a partner who can deliver high quality products, service, design expertise and innovation, efficient operations and timely delivery of components to their assembly facilities, both regionally and nationwide. Our goal is to offer a broad and relevant range of products to our customers so they can focus on assembly, delivery of finished goods, brand awareness, product marketing, and dealer relationships. We supply critical and highly visible interior and exterior components that differentiate our customers’ products in the RV, MH, and Industrial markets.

As a result of our longstanding relationships with many of the largest players in our markets, our customers encourage us to supply new or extended categories of products in order to help them drive efficiencies with the same level of quality and service. We have provided these expanded offerings either by acquiring companies with strong product niches that we can leverage across our network or through new product development.

When we acquire companies to expand our geographic and product reach, we typically seek to integrate certain functions that are best managed centrally, such as administrative, finance, legal, information technology, and human resources while allowing our acquired businesses to retain significant autonomy which fosters entrepreneurial spirit and brand individuality, and in turn enables the continuation of legacy value propositions for customers.

OUR COMPETITIVE STRENGTHS

A Leading Provider of Components to RV, MH and Industrial End Markets

We are a leading provider of a range of core components that go into the RV, MH and Industrial end markets. The RV market has experienced several years of recovery and growth driven by increased consumer interest in spending quality time with family and the recreational lifestyle. This shift in consumer behavior is driven by favorable demographic trends, including a growing interest in experiences, especially active and outdoor activities, among the emerging “millennial” and minority demographic and the increasing population of aging, retiring “baby boomers” who have the disposal income and time to pursue RV’ing. Additionally, all three of our segments have benefitted from increased consumer confidence, expanded credit availability, and lower unemployment, aiding our growth.

Robust Opportunities across Diverse Range of End Markets

We believe there are significant opportunities to grow within our established end markets while also expanding operations into new markets, such as marine. As a result of our presence across multiple recreational lifestyle categories, as well as MH and residential and commercial construction, our revenue is not solely dependent on a single end market. We believe each of these end markets has a favorable growth outlook.

Ability to Steadily Increase Content Revenue per Unit in RV and MH Markets

We experienced RV unit content growth of 15% and MH unit content growth of 8% in 2016 compared to 2015. This growth was driven by new products, extension growth, acquisitions and market share gain. We estimate that our current revenue opportunity in existing products is $6,300 per RV unit and $6,900 per MH unit.

Leadership in New Product Introductions

New product introductions and product line extensions are key components of our strategy to grow our market share and revenue base, adapt to changing market conditions, and proactively address customer demand. We believe there are numerous opportunities to launch product line extensions in our RV and MH product lines. Our commitment to design and innovation allows us to increase our presence in the markets that we serve and gain entrance into other markets. Over the last three years, we have introduced over 300 new products and product lines extensions to the market through acquisitions and internal development.

Continued Expansion into Complementary End Markets to Core RV Sales

Over the last several years, we have targeted certain sales efforts towards market segments that are less directly tied to recreational vehicle and residential new home construction, including the retail fixture, furniture, and countertop markets. As a result, we have seen a shift in our product mix, which has had a positive impact on revenues from the Industrial markets. Additionally, we have gained market share and expanded into new geographic territories as a result of acquisitions and investment in new team members with significant product knowledge, relationships, and expertise in the commercial markets.

Proven and Active Industry Consolidator

We have a track record of successfully executing small- and mid-sized acquisitions. We are focused on driving growth in each of our primary markets through the opportunistic acquisition of companies with strong management teams having a strategic fit with Patrick’s core values, business model, and customer presence, as well as additional product lines, facilities, or other assets to complement or expand our existing businesses. Since 2010, we have acquired 31 component manufacturers and distributors that have added breadth and depth to our product offering. The OEM supplier landscape includes numerous suppliers and remains highly fragmented, providing additional opportunity for growth through acquisitions. Our disciplined, focused acquisition strategy is to target acquisitions that can strengthen or broaden our product offering and achieve established payback hurdles. To facilitate ongoing acquisition activity, we plan to continue to utilize our methodical, strategic and value-driven approach to consolidating a highly fragmented industry with a long tail of attractive targets.

Proven Management Team that has Successfully Managed the Company Through Different Business Environments and Executed on a Successful Growth Strategy

Our experienced executive management team, including Todd Cleveland, Andy Nemeth, Jeff Rodino, Joshua Boone, and Kip Ellis, combines deep industry expertise and experience with mergers and acquisitions with more than 100 years of cumulative experience. The team demonstrated its knowledge and expertise by managing our business successfully through the last economic downturn.

Net Sales by Segment, Product, and End Market:

MARKETS

We supply highly visible interior and exterior components that differentiate our customers’ products in the RV, MH, and Industrial markets. We have consistently captured market share through our new product initiatives and strategic acquisitions, resulting in sales levels growing at a rate in excess of the general industry over the last five years.

The RV industry has demonstrated continued growth in the past three years with broad-based demand strength across towable and motorized product categories. According to the Recreation Vehicle Industry

S-4

Table of Contents

Association (“RVIA”), as noted in its December 2016 Recreation Vehicle Market Report, RV shipments surpassed 430,000 units in 2016, representing a 15% increase over 2015. We believe factors that support RV demand include: consumer wealth, consumer confidence, availability of financing and levels of disposable income. We believe the current economic environment and these factors provide for a near-term positive RV outlook with favorable secular trends in RV ownership, outdoor lifestyle and demographics driving long-term industry growth. We believe society is increasingly participating in nature-based tourism activities, with “millennials” and minorities embracing the outdoor lifestyle and entering into the RV marketplace. According to the RVIA, RV sales will continue to benefit from ongoing aging of the “baby boomers” as more people enter the primary RV ownership age group of 55 to 70 years old.

The marine industry has been improving over the past few years and we believe there is meaningful growth ahead in this industry. With similar demand factors as RVs, we believe a continued improvement in economic conditions will contribute to a marine market recovery. According to the National Marine Manufacturers Association, preliminary data indicates that 2016 new power boat registrations increased 6% year over year. In addition, current power boat sales levels still remain significantly below the 1984 to 2015 annual average of approximately 307,000 units, suggesting growth potential.

The MH industry has demonstrated steady growth in the last three years with increased levels of wholesale shipments. We continue to believe there is pent up demand and upside potential for this market based on improving residential housing market conditions, high consumer confidence levels, increased affordability and quality, and improving credit and financing considerations. The MH industry, however, continues to face some challenges presented by the lack of financing alternatives and credit availability.

Therefore, there is a correlation between the demand for our products in this market and new residential housing construction and remodeling activities. With housing starts projected to increase by 8% and 9% in 2017 and 2018, respectively, according to the National Association of Realtors U.S. Economic Outlook as of February 2017, we believe the positive momentum in both our MH and Industrial segments will continue to increase.

RISK FACTORS

Investing in our common stock involves a high degree of risk. You should carefully consider the risks described below and the information set forth in the accompanying prospectus to this prospectus supplement and in our Annual Report on Form 10-K for the year ended December 31, 2016, together with all other information included or incorporated by reference into this prospectus supplement and the accompanying prospectus, before you decide to invest in our common stock. The risks and uncertainties described in such incorporated documents and described below are not the only risks and uncertainties we face. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also impair our business operations. If any of those risks actually occurs, our business, financial condition and results of operations would suffer. In that event, the trading price of our common stock could decline, and you may lose all or part of your investment. The risks discussed below also include forward-looking statements and our actual results may differ substantially from those discussed in these forward-looking statements. See “Cautionary Note Regarding Forward-Looking Statements” below.

Economic and business conditions beyond Patrick’s control, including cyclicality and seasonality in the industries it sells products, could lead to fluctuations in and negatively impact operating results.

The RV, MH and Industrial markets in which we operate are subject to cycles of growth and contraction in consumer demand, and volatility in production levels, shipments, sales and operating results, due to external factors such as general economic conditions, consumer confidence, employment rates, financing availability, interest rates, inflation, fuel prices, and other economic conditions affecting consumer demand and discretionary spending. Periods of economic recession and downturns have adversely affected our business and operating results in the past, and have the potential to adversely impact our future results. Consequently, the results for any prior period may not be indicative of results for any future period. In addition, fluctuation in demand could adversely affect our management of inventory, which could lead to an inability to meet customer needs or a charge for obsolete inventory.

Sales in the RV and MH markets historically have been seasonal and are generally at the highest levels when the climate is moderate. However, seasonal industry trends in the past several years have differed from prior years, primarily due to volatile economic conditions, fluctuations in RV dealer inventories, changing dealer show schedules, interest rates, access to financing, the cost of fuel, and increased demand from RV dealers. Consequently, future seasonal trends may differ from prior years. In addition, unusually severe weather conditions may impact the timing of industry-wide shipments from one period to another and lead to unanticipated fluctuations in our operating results.

If the financial condition of our customers and suppliers deteriorates, our business and operating results could suffer.

The markets we serve have been highly sensitive to changes in the economic environment. Weakening conditions in the economy, or the lack of available financing in the credit market, could cause the financial condition of our customers and suppliers to deteriorate, which could negatively affect our business through the loss of sales or the inability to meet our commitments. Many of our customers participate in highly competitive markets and their financial condition may deteriorate as a result. In addition, a decline in the financial condition of our customers could hinder our ability to collect amounts owed by customers.

Although we have a large number of customers, our sales are significantly concentrated with two customers, the loss of either of which could have a material adverse impact on our operating results and financial condition.

Two customers in the RV market accounted for a combined 60% of our consolidated net sales in 2016. The loss of either of these customers could have a material adverse impact on our operating results and financial

Table of Contents

condition. We do not have long-term agreements with our customers and cannot predict that we will maintain our current relationships with these customers or that we will continue to supply them at current levels.

Changes in consumer preferences relating to our products could adversely impact our sales levels and our operating results.

Changes in consumer preferences, or our inability to anticipate changes in consumer preferences for RVs or manufactured homes, or for the products we make could reduce demand for our products and adversely affect our operating results and financial condition.

A significant percentage of the Company’s sales are concentrated in the RV market, and declines in the level of RV unit shipments or reductions in industry growth could reduce demand for our products and adversely impact our operating results and financial condition.

In both 2015 and 2016, the Company’s net sales to the RV market were approximately 75% of consolidated net sales. While the Company measures its RV segment sales against industry-wide wholesale shipment statistics, the underlying health of the RV market is determined by retail demand. Retail sales of RVs historically have been closely tied to general economic conditions, as well as consumer confidence, which was above historical averages in 2016. Future declines in RV unit shipment levels or reductions in industry growth could significantly reduce the Company’s revenue from the RV market and have a material adverse impact on its operating results in 2017 and other future periods.

The manufactured housing and recreational vehicle industries are highly competitive and some of our competitors may have greater resources than we do.

We operate in a highly competitive business environment and our sales could be negatively impacted by our inability to maintain or increase prices, changes in geographic or product mix, or the decision of our customers to purchase our competitors’ products or to produce in-house products that we currently produce. We compete not only with other suppliers to the RV and MH producers, but also with suppliers to traditional site-built homebuilders and suppliers of cabinetry and countertops. Sales could also be affected by pricing, purchasing, financing, advertising, operational, promotional, or other decisions made by purchasers of our products. Additionally, we cannot control the decisions made by suppliers of our distributed and manufactured products, and therefore, our ability to maintain our distribution arrangements may be adversely impacted.

The greater financial resources or the lower level of debt or financial leverage of certain of our competitors may enable them to commit larger amounts of capital in response to changing market conditions. Competitors may develop innovative new products that could put the Company at a competitive disadvantage. If we are unable to compete successfully against other manufacturers and suppliers to the RV and MH markets, we could lose customers and sales could decline, or we may not be able to improve or maintain profit margins on sales to customers or be able to continue to compete successfully in our core markets.

Conditions in the credit market could limit the ability of consumers to obtain retail financing for RVs and manufactured homes, resulting in reduced demand for our products.

Restrictions on the availability of consumer financing for RVs and manufactured homes and increases in the costs of such financing have in the past limited, and could again limit, the ability of consumers to purchase RVs and manufactured homes, which would result in reduced production of RVs and manufactured homes by our customers, and therefore reduce demand for our products.

Loans used to finance the purchase of manufactured homes usually have shorter terms and higher interest rates, and are more difficult to obtain than mortgages for site-built homes. Historically, lenders required a higher down payment, higher credit scores and other criteria for these loans. Current lending criteria are more stringent than historical criteria, and many potential buyers of manufactured homes may not qualify.

S-11

Table of Contents

The availability, cost, and terms of these manufactured housing loans are also dependent on economic conditions, lending practices of financial institutions, government policies, and other factors, all of which are beyond our control. Reductions in the availability of financing for manufactured homes and increases in the costs of financing have limited, and could continue to limit, the ability of consumers to purchase manufactured homes, resulting in reduced production of manufactured homes by our customers, and therefore reduced demand for our products. In addition, certain provisions of the Dodd-Frank Act, which regulate financial transactions, could make certain types of loans more difficult to obtain, including those historically used to finance the purchase of manufactured homes.

The manufactured housing industry has experienced a significant long-term decline in shipments, which has led to reduced demand for our products.

Our MH segment, which accounted for 13% of consolidated net sales for 2016, operates in an industry which has experienced a significant decline in production of new homes compared to the last peak production level in 1998. The downturn was caused, in part, by limited availability and high cost of financing for manufactured homes, and was exacerbated by economic and political conditions during the financial crisis. Although industry-wide wholesale production of manufactured homes has improved somewhat in recent years, a worsening of conditions in the MH market could have a material adverse impact on our operating results.

Fuel shortages or high prices for fuel could have an adverse impact on our operations.

The products produced by the RV market typically require gasoline or diesel fuel for their operation, or the use of a vehicle requiring gasoline or diesel fuel for their operation. There can be no assurance that the supply of gasoline and diesel fuel will continue uninterrupted or that the price or tax on fuel will not significantly increase in the future. Shortages of gasoline and diesel fuel, and substantial increases in the price of fuel, have had a material adverse effect on our business and the RV industry as a whole in the past and could have a material adverse effect on our business in the future.

We are dependent on third-party suppliers and manufacturers.

Generally, our raw materials, supplies and energy requirements are obtained from various sources and in the quantities desired. While alternative sources are available, our business is subject to the risk of price increases and periodic delays in delivery. Fluctuations in prices may be driven by the supply/demand relationship for that commodity, governmental regulation, tariffs or other cross-border taxes, economic conditions in other countries, religious holidays, natural disasters, and other events. In addition, if any of our suppliers seek bankruptcy relief or otherwise cannot continue their business as anticipated, the availability or price of these requirements could be adversely affected.

If we cannot effectively manage the challenges and risks associated with doing business internationally, our revenues and profitability may suffer.

We purchase a significant portion of our raw materials and other supplies from suppliers located in Indonesia, China and Malaysia. As a result, our ability to obtain raw materials and supplies on favorable terms and in a timely fashion are subject to a variety of risks, including fluctuations in foreign currencies, changes in the economic strength of the foreign countries in which we do business, difficulties in enforcing contractual obligations and intellectual property rights, compliance burdens associated with a wide variety of international and United States import laws, and social, political, and economic instability. Our business with our international suppliers could be adversely affected by restrictions on travel to and from any of the countries in which we do business due to a health epidemic or outbreak or other event. Additional risks associated with our foreign business include restrictive trade policies, imposition of duties, taxes, or government royalties by foreign governments, and compliance with the Foreign Corrupt Practices Act and local anti-bribery laws. Recently, the new White House administration, certain members of Congress and key policy makers have suggested the

S-12

Table of Contents

renegotiation of the North American Free Trade Agreement. In addition, the new administration has suggested the adoption of other laws to implement tariffs, border taxes, or other measures that could impact the level of trade between the U.S., Mexico and China. Any such proposals or measures could negatively impact our relations with our international suppliers and the volume of shipments to the U.S. from these countries, which could have a material adverse effect on our business and operating results.

Any increased cost and limited availability of certain raw materials may have a material adverse effect on our business and results of operations.

Prices of certain materials, including gypsum, lauan, particleboard, MDF, aluminum and other commodity products, can be volatile and change dramatically with changes in supply and demand. Certain products are purchased from overseas and their availability is dependent upon weather conditions, seasonal and religious holidays, political unrest, economic conditions overseas, natural disasters, vessel shipping schedules and port availability. Further, our commodity product suppliers sometimes operate at or near capacity, resulting in some products having the potential of being put on allocation. We generally have been able to maintain adequate supplies of materials and pass higher material costs on to our customers in the form of surcharges and base price increases where needed. However, it is not certain future price increases can be passed on to our customers without affecting demand or that limited availability of materials will not impact our production capabilities. Our sales levels and operating results could be negatively impacted by changes in any of these items.

Increases in demand for our products could make it more difficult for us to obtain additional skilled labor, which may adversely impact our operating efficiencies.

In certain geographic regions in which we have manufacturing facilities, we are experiencing shortages of qualified employees, which negatively impacted our cost of goods sold in 2016. Labor shortages and continued competition for qualified employees may increase the cost of our labor and create employee retention and recruitment challenges, especially during improving economic times as employees with knowledge and experience have the ability to change employers more easily.

If demand continues to increase, we may not be able to increase production to satisfy demand in a timely fashion, and may initially incur higher labor and production costs, which could adversely impact our financial condition and operating results.

We may incur significant charges or be adversely impacted by the consolidation and/or closure of all or part of a manufacturing or distribution facility.

We periodically assess the cost structure of our operating facilities to distribute and/or manufacture products in the most efficient manner. We may make capital investments to move, discontinue manufacturing and/or distribution capabilities, or products and product lines, sell or close all or part of additional manufacturing and/or distribution facilities in the future. These changes could result in significant future charges or disruptions in our operations, and we may not achieve the expected benefits from these changes, which could result in an adverse impact on our operating results, cash flows, and financial condition.

We are subject to governmental and environmental laws and regulations, and failure in our compliance efforts, changes to such laws and regulations or events beyond our control could result in damages, expenses or liabilities that individually, or in the aggregate, would have a material adverse effect on our financial condition and results of operations.

Some of our manufacturing processes involve the use, handling, storage and contracting for recycling or disposal of hazardous or toxic substances or wastes. Accordingly, we are subject to various governmental and environmental laws and regulations regarding these substances, as well as environmental requirements relating to air, water and noise pollution. The implementation of new laws and regulations or amendments to existing laws

S-13

Table of Contents

and regulations could significantly increase the cost of the Company’s products. We cannot presently determine what, if any, legislation may be adopted by federal, state or local governing bodies, or the effect any such legislation may have on our customers or us. Failure to comply with present or future laws and regulations could result in fines or potential civil or criminal liability. Both scenarios could negatively impact our results of operations or financial condition.

The inability to attract and retain qualified executive officers and key personnel may adversely affect our operations.

While we include succession planning as part of our ongoing talent development and management process to help ensure the continuity of our business model, the loss of any of our executive officers or other key personnel could reduce our ability to manage our business and strategic plan in the short-term and could cause our sales and operating results to decline. In addition, our future success will depend on, among other factors, our ability to attract and retain executive management, key employees, and other qualified personnel.

Our ability to integrate acquired businesses may adversely affect operations.

As part of our business and strategic plan, we look for strategic acquisitions to provide shareholder value. Any acquisition will require the effective integration of an existing business and its administrative, financial, sales and marketing, manufacturing, and other functions to maximize synergies. Acquired businesses involve a number of risks that may affect our financial performance, including increased leverage, diversion of management resources, assumption of liabilities of the acquired businesses, and possible corporate culture conflicts. If we are unable to successfully integrate these acquisitions, we may not realize the benefits identified in our due diligence process, and our financial results may be negatively impacted. Additionally, significant unexpected liabilities could arise from these acquisitions.

Our level of indebtedness could limit our operational flexibility and harm our financial condition and results of operations.

As of December 31, 2016, we had $273.0 million of total long-term debt outstanding under our $360.0 million revolving credit facility (the “2015 Credit Facility”) that was established pursuant to our current credit agreement, as amended (the “2015 Credit Agreement”). Our level of indebtedness could have adverse consequences on our future operations, including making it more difficult for us to meet our payments on outstanding debt, and we may not be able to find alternative financing sources to replace our indebtedness in such an event. Our level of indebtedness could: (i) reduce the availability of our cash flow to fund working capital, capital expenditures, acquisitions and other general corporate purposes, and limit our ability to obtain additional financing for these purposes; (ii) limit our flexibility in planning for, or reacting to, and increasing our vulnerability to, changes in our business and the industry in which we operate; (iii) place us at a competitive disadvantage compared to our competitors that have less debt or are less leveraged; and (iv) create concerns about our credit quality which could result in the loss of supplier contracts and/or customers. Our ability to satisfy our debt obligations will depend on our future operating performance which may be affected by factors beyond our control.

Our 2015 Credit Agreement contains various financial performance and other covenants. If we do not remain in compliance with these covenants, our 2015 Credit Agreement could be terminated and the amounts outstanding thereunder could become immediately due and payable.

We have debt outstanding that contains financial and non-financial covenants with which we must comply that place restrictions on us. There can be no assurance that we will maintain compliance with the financial covenants under our 2015 Credit Agreement. These covenants require that we comply with a maximum level of a consolidated total leverage ratio and a minimum level of a consolidated fixed charge coverage ratio. If we fail to comply with the covenants contained in our 2015 Credit Agreement, the lenders could cause our debt

to become due and payable prior to maturity or it could result in our having to refinance the indebtedness under unfavorable terms. If our debt were accelerated, our assets might not be sufficient to repay our debt in full and there can be no assurance that we would be able to refinance any or all of our indebtedness.

Due to industry conditions and our operating results, there have been times in the past when we have had limited access to sources of capital. If we are unable to locate suitable sources of capital when needed, we may be unable to maintain or expand our business.

We depend on our cash balances, our cash flows from operations, and our 2015 Credit Facility to finance our operating requirements, capital expenditures and other needs. If a significant economic recession occurred, such as the recession that impacted the economy from 2007 to 2010, production of RVs and manufactured homes could decline, resulting in reduced demand for our products. A decline in our operating results could negatively impact our liquidity. If our cash balances, cash flows from operations, and availability under our 2015 Credit Facility are insufficient to finance our operations and alternative capital is not available, we may not be able to expand our business and make acquisitions, or we may need to curtail or limit our existing operations.

We have letters of credit representing collateral for our casualty insurance programs and for general operating purposes that have been issued under our 2015 Credit Facility. The inability to retain our current letters of credit, to obtain alternative letter of credit sources, or to retain our 2015 Credit Facility to support these programs could require us to post cash collateral, reduce the amount of cash available for our operations, or cause us to curtail or limit existing operations.

If we are unable to manage our inventory, our operating results could be materially and adversely affected.

Our customers generally do not maintain long-term supply contracts and, therefore, we must bear the risk of advanced estimation of customer orders. We maintain inventory to support these customers’ needs. Changes in demand, market conditions and/or product specifications could result in material obsolescence and a lack of alternative markets for certain of our customer specific products and could negatively impact operating results.

We could incur charges for impairment of assets, including goodwill and other long-lived assets, due to potential declines in the fair value of those assets or a decline in expected profitability of the Company or individual reporting units of the Company.

Approximately 67% of our total assets as of December 31, 2016 was comprised of goodwill, other intangible assets, and property, plant and equipment. Under generally accepted accounting principles, each of these assets is subject to periodic review and testing to determine whether the asset is recoverable or realizable. The events or changes that could require us to test our goodwill and intangible assets for impairment include changes in our estimated future cash flows, changes in rates of growth in our industry or in any of our reporting units, and decreases in our stock price and market capitalization.

In the future, if sales demand or market conditions change from those projected by management, asset write-downs may be required. Significant impairment charges, although not always affecting current cash flow, could have a material effect on our operating results and financial position.

A variety of factors, many of which are beyond our control, could influence fluctuations in the market price for our common stock.

The stock market, in general, experiences volatility that has often been unrelated to the underlying operating performance of companies. If this volatility continues, the trading price of our common stock could decline significantly, independent of our actual operating performance. The market price of our common stock

S-15

Table of Contents

could fluctuate significantly in response to a number of factors, many of which are beyond our control, including the following:

If our information technology systems fail to perform adequately, our operations could be disrupted and could adversely affect our business, reputation and results of operation.

We are increasingly dependent on digital technology, including information systems and related infrastructure, to process and record financial and operating data, manage inventory and communicate with our employees and business partners. We rely on our information technology systems to effectively manage our business data, inventory, supply chain, order entry and fulfillment, manufacturing, distribution, warranty administration, invoicing, collection of payments, and other business processes. Our systems are subject to damage or interruption from power outages, telecommunications or internet failures, computer viruses and malicious attacks, security breaches and catastrophic events. If our systems are damaged or fail to function properly or reliably, we may incur substantial repair or replacement costs, experience data loss or theft and impediments to our ability to manage our business, which could adversely affect our results of operations. Any such events could result in legal claims or proceedings, liability or penalties under privacy laws, disruption in operations, and damage to our reputation, which could adversely affect our business.

In addition, we may be required to make significant technology investments to maintain and update our existing computer systems. Implementing significant system changes increases the risk of computer system disruption. The potential problems and interruptions associated with implementing technology initiatives could disrupt or reduce our operational efficiency.

A cyber incident or data breach could result in information theft, data corruption, operational disruption, and/or financial loss.

Our technologies, systems, networks, and those of our business partners have in the past and may in the future become the target of cyber-attacks or information security breaches that could result in the unauthorized

S-16

Table of Contents

release, gathering, monitoring, misuse, loss, or destruction of proprietary and other information, or other disruption of our business operations. A cyber-attack could include gaining unauthorized access to digital systems for purposes of misappropriating assets or sensitive information, corrupting data, or causing operational disruption or result in denial of service on websites. We have programs in place to detect, contain and respond to data security incidents. However, because the techniques used to obtain unauthorized access, disable or degrade service, or sabotage systems change frequently and may be difficult to detect for long periods of time, we may be unable to anticipate these techniques or implement adequate preventive measures. Unauthorized parties may also attempt to gain access to our systems or facilities, or those of third parties with whom we do business, through fraud, trickery, or other forms of deceiving our team members, contractors, vendors, and temporary staff. In addition, hardware, software, or applications we develop or procure from third parties may contain defects in design or manufacture or other problems that could unexpectedly compromise information security. Any cyber-attack on our business could materially harm our business and operating results. On February 3, 2017, certain personally identifiable employee information for all of the Company’s current and former employees for calendar year 2016 was inadvertently disclosed to an unauthorized individual or individuals as the result of a targeted email phishing message. The Company currently carries insurance to cover its exposure to this type of incident. As cyber threats continue to evolve, we may be required to expend significant additional resources to continue to modify or enhance our protective measures or to investigate and remediate any information security vulnerabilities. If we or our suppliers experience additional significant data security breaches or fail to detect and appropriately respond to significant data security breaches, we could be exposed to costly government enforcement actions and private litigation and our business and operating results could suffer.

We are required to evaluate our internal controls over financial reporting under Section 404 of the Sarbanes-Oxley Act of 2002 and any adverse results from such evaluation could result in a loss of investor confidence in our financial reports and could have an adverse effect on our stock price.

Pursuant to Section 404 of the Sarbanes-Oxley Act of 2002, we are required to furnish a report by our management on our internal control over financial reporting. Such report contains, among other matters, an assessment of the effectiveness of our internal control over financial reporting as of the end of our fiscal year, including a statement as to whether or not our internal control over financial reporting is effective. This assessment must include disclosure of any material weaknesses in our internal control over financial reporting identified by management. Each year we must prepare or update the process documentation and perform the evaluation needed to comply with Section 404. During this process, if our management identifies one or more material weaknesses in our internal control over financial reporting, we will be unable to assert that such internal control is effective. Ensuring that we have adequate internal financial and accounting controls and procedures in place is a costly and time-consuming effort that needs to be re-evaluated frequently. We and our independent auditors may in the future discover areas of our internal controls that need further attention and improvement, particularly with respect to any businesses that we decide to acquire in the future. Any failure to implement required new or improved controls, or difficulties encountered in their implementation, could harm our operating results or cause us to fail to meet our reporting obligations. Investor perception that our internal controls are inadequate or that we are unable to produce accurate financial statements on a timely, consistent basis may adversely affect our stock price. Failure to comply with Section 404 could also potentially subject us to sanctions or investigations by the SEC, NASDAQ, or other regulatory authorities.

Certain provisions in our Articles of Incorporation and Amended and Restated By-laws may delay, defer or prevent a change in control that our shareholders each might consider to be in their best interest.

Our Articles of Incorporation and Amended and Restated By-laws contain provisions that are intended to deter coercive takeover practices and inadequate takeover bids. These provisions may delay, defer or prevent a change in control that our shareholders might consider to be in their best interest.

Conditions within the insurance markets could impact our ability to negotiate favorable terms and conditions for various liability coverage and could potentially result in uninsured losses.

We generally negotiate our insurance contracts annually for property, casualty, workers’ compensation, general liability, health insurance, and directors and officers liability coverage. Due to conditions within these insurance markets and other factors beyond our control, future coverage limits, terms and conditions and the amount of the related premiums could have a negative impact on our operating results. While we continually measure the risk/reward of policy limits and coverage, the lack of coverage in certain circumstances could result in potential uninsured losses.

Risks Related to our Common Stock

The price of our shares of common stock may be volatile.

The trading price of shares of our common stock may fluctuate substantially. In particular, it is possible that our operating results, including the integration of recent acquisitions into our operations, may be below the expectations of public market analysts and investors, and, as a result of these and other factors, the price of our common stock may decline. These fluctuations could cause you to lose part or all of your investment in shares of our common stock. Factors that could cause fluctuations include, but are not limited to, the following:

The stock markets, in general, periodically experience volatility that is sometimes unrelated to the operating performance of particular companies. These broad market fluctuations may cause the trading price of our common stock to decline.

There may be future sales or issuances of our common stock, which will dilute the ownership interests of stockholders and may adversely affect the market price of our common stock.

We may issue additional common stock, including securities that are convertible into or exchangeable for, or that represent the right to receive, common stock or substantially similar securities, which may result in dilution to our stockholders. In addition, our stockholders may be further diluted by future issuances under our equity incentive plans. Sales of substantial amounts of common stock by us or our stockholders in the public

Table of Contents

market could adversely affect the market price of the common stock. The market price of our common stock could decline as a result of sales or issuances of a large number of our common stock or similar securities in the market after this offering or the perception that such sales or issuances could occur.

If securities or industry analysts do not publish research or reports about our business or publish unfavorable research, or our results are below analysts’ estimates, our stock price and trading volume could decline.

The trading market for our common stock may depend on the research and reports that industry or securities analysts publish about us or our business. We do not have any control over these analysts. If one or more of the analysts who cover us downgrade our stock or our results are below analysts’ estimates, our stock price would likely decline. If one or more of these analysts cease to cover the Company or fail to regularly publish reports on us, we could lose visibility in the financial markets, which in turn could cause our stock price or trading volume to decline. Moreover, if our operating results do not meet the expectations of the investor community, it is possible that the analysts who cover us may change their recommendations regarding the Company, and our stock price could decline.

We do not currently intend to pay cash dividends on our common stock to our stockholders and any determination to pay cash dividends in the future will be at the discretion of our Board of Directors.

We currently intend to retain any profits for use in the operation and expansion of our business and payment of our outstanding debt. Our Board of Directors does not intend to declare cash dividends in the foreseeable future. Any determination to pay dividends to our stockholders in the future will be at the discretion of our Board of Directors and will depend on our results of operations, financial condition, and other factors deemed relevant by our Board of Directors. In addition, our 2015 Credit Agreement prohibits us from paying cash dividends on our common stock. Consequently, it is uncertain when, if ever, we will declare dividends to our stockholders. If we do not pay dividends, investors will only obtain a return on their investment if the value of our shares of common stock appreciates.

USE OF PROCEEDS

We estimate that the net proceeds from the sale of shares of our common stock in this offering will be approximately $93.2 million (or approximately $107.3 million if the underwriters exercise their option in full), based on the public offering price of $73.00 per share, after deducting the underwriting discount and commissions and estimated offering expenses payable by us.

We intend to use all of the net proceeds from this offering to pay down a portion of our indebtedness under our 2015 Credit Facility. As of March 3, 2017, we had approximately $212.0 million of indebtedness under the revolving loan portion of our 2015 Credit Facility and $82.7 million of indebtedness under our credit facility term loan. This indebtedness matures on April 28, 2020 and has an effective interest rate of 2.562%.

Affiliates of certain of the underwriters are lenders under our 2015 Credit Facility and may receive a portion of the net proceeds of this offering. Because of the manner in which the proceeds will be used, this offering will be conducted in accordance with FINRA 5121. In accordance with that rule, no “qualified independent underwriter” is required because a bona fide public market exists in the shares, as that term is defined in the rule. See “Underwriting (Conflicts of Interest)—Conflicts of Interest.”

PRICE RANGE OF OUR COMMON STOCK AND DIVIDEND POLICY

Our common stock is traded on the NASDAQ Global Select Market under the symbol “PATK”. On March 8, 2017, the closing price of our common stock on the NASDAQ Global Select Market was $75.20. The following table sets forth, for the time periods indicated, the high and low sales prices of our common stock as reported on the NASDAQ Global Select Market.

The quotations represent prices between dealers, do not include retail mark-ups, mark-downs, or commissions, and may not necessarily represent actual transactions.

Holders of Common Stock

As of March 3, 2017, there were 275 holders of record of common stock. Several brokerage firms, banks, and other institutions (“nominees”) are listed once on the stockholders of record listing. In most cases, the nominees’ holdings represent blocks of our common stock held in brokerage accounts for a number of individual stockholders. As such, our actual number of stockholders would be higher than the number of registered stockholders of record.

Dividend Policy

We do not intend to pay any dividends on our common stock in the foreseeable future. We intend to retain any future earnings for use in the operation and expansion of our business and payment of our outstanding debt. In addition, our 2015 Credit Agreement prohibits us from paying cash dividends on our common stock.

CAPITALIZATION

The following table sets forth our capitalization as of December 31, 2016 on an actual basis and as adjusted basis to give effect to the sale of 1,350,000 shares of our common stock in this offering by us (assuming the underwriters do not exercise their option to purchase additional shares of our common stock) at a public offering price of $73.00 per share, and the application of the net proceeds as contemplated in “Use of Proceeds”.

You should read the data set forth below in conjunction with our “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and our consolidated financial statements and accompanying notes included in our Annual Report or 10-K for the year ended December 31, 2016, which is incorporated by reference in this prospectus supplement and the accompanying prospectus.

UNDERWRITING (CONFLICTS OF INTEREST)

Merrill Lynch, Pierce, Fenner & Smith Incorporated, Wells Fargo Securities, LLC and Robert W. Baird & Co. Incorporated are acting as representatives of each of the underwriters named below. Subject to the terms and conditions set forth in an underwriting agreement among us and the underwriters, we have agreed to sell to the underwriters, and each of the underwriters has agreed, severally and not jointly, to purchase from us, the number of shares of common stock set forth opposite its name below.

Subject to the terms and conditions set forth in the underwriting agreement, the underwriters have agreed, severally and not jointly, to purchase all of the shares sold under the underwriting agreement if any of these shares are purchased. If an underwriter defaults, the underwriting agreement provides that the purchase commitments of the nondefaulting underwriters may be increased or the underwriting agreement may be terminated.

We have agreed to indemnify the underwriters against certain liabilities, including liabilities under the Securities Act, or to contribute to payments the underwriters may be required to make in respect of those liabilities.

The underwriters are offering the shares, subject to prior sale, when, as and if issued to and accepted by them, subject to approval of legal matters by their counsel, including the validity of the shares, and other conditions contained in the underwriting agreement, such as the receipt by the underwriters of officer’s certificates and legal opinions. The underwriters reserve the right to withdraw, cancel or modify offers to the public and to reject orders in whole or in part.

Commissions and Discounts

The representatives have advised us that the underwriters propose initially to offer the shares to the public at the public offering price set forth on the cover page of this prospectus supplement and to dealers at that price less a concession not in excess of $2.19 per share. After the initial offering, the public offering price, concession or any other term of the offering may be changed.

The following table shows the public offering price, underwriting discount and proceeds before expenses to us. The information assumes either no exercise or full exercise by the underwriters of their option to purchase additional shares.

The expenses of the offering, not including the underwriting discount, are estimated at $400,000 and are payable by us.

Table of Contents

Option to Purchase Additional Shares

We have granted an option to the underwriters, exercisable for 30 days after the date of this prospectus supplement, to purchase up to 202,500 additional shares at the public offering price, less the underwriting discount. If the underwriters exercise this option, each will be obligated, subject to conditions contained in the underwriting agreement, to purchase a number of additional shares proportionate to that underwriter’s initial amount reflected in the above table.

No Sales of Similar Securities

We have agreed for 90 days after the date of this prospectus supplement, and our executive officers and directors and certain stockholders have agreed, subject to certain exceptions, for 60 days after the date of this prospectus supplement, not to sell or transfer any common stock or securities convertible into, exchangeable for, exercisable for, or repayable with common stock, without first obtaining the written consent of Merrill Lynch, Pierce, Fenner & Smith Incorporated and Wells Fargo Securities, LLC. Specifically, we and these other persons have agreed, with certain limited exceptions, not to directly or indirectly:

Such exceptions include, among others, any shares of common stock or any securities convertible into or exercisable or exchangeable for common stock that we issue in connection with acquisitions, joint ventures and similar types of arrangements of up to 5% of outstanding common stock in aggregate at the time of the underwriting agreement, as long as the recipients of such securities also agree not to sell or transfer those securities without the prior written consent of Merrill Lynch, Pierce, Fenner & Smith Incorporated and Wells Fargo Securities, LLC for a period of 90 days from the date of this prospectus supplement.

This lock-up provision applies to common stock and to securities convertible into or exchangeable or exercisable for or repayable with common stock. It also applies to common stock owned now or acquired later by the person executing the agreement or for which the person executing the agreement later acquires the power of disposition.

Nasdaq Global Select Market Listing

The shares are listed on the Nasdaq Global Select Market under the symbol “PATK.”

Price Stabilization, Short Positions

Until the distribution of the shares is completed, SEC rules may limit underwriters and selling group members from bidding for and purchasing our common stock. However, the representatives may engage in transactions that stabilize the price of the common stock, such as bids or purchases to peg, fix or maintain that price.

S-26

Table of Contents

In connection with the offering, the underwriters may purchase and sell our common stock in the open market. These transactions may include short sales, purchases on the open market to cover positions created by short sales and stabilizing transactions. Short sales involve the sale by the underwriters of a greater number of shares than they are required to purchase in the offering. “Covered” short sales are sales made in an amount not greater than the underwriters’ option to purchase additional shares described above. The underwriters may close out any covered short position by either exercising their option to purchase additional shares or purchasing shares in the open market. In determining the source of shares to close out the covered short position, the underwriters will consider, among other things, the price of shares available for purchase in the open market as compared to the price at which they may purchase shares through the option granted to them. “Naked” short sales are sales in excess of such option. The underwriters must close out any naked short position by purchasing shares in the open market. A naked short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of our common stock in the open market after pricing that could adversely affect investors who purchase in the offering. Stabilizing transactions consist of various bids for or purchases of shares of common stock made by the underwriters in the open market prior to the completion of the offering.

Similar to other purchase transactions, the underwriters’ purchases to cover the syndicate short sales may have the effect of raising or maintaining the market price of our common stock or preventing or retarding a decline in the market price of our common stock. As a result, the price of our common stock may be higher than the price that might otherwise exist in the open market. The underwriters may conduct these transactions on the Nasdaq Global Select Market, in the over-the-counter market or otherwise.

Neither we nor any of the underwriters make any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the price of our common stock. In addition, neither we nor any of the underwriters make any representation that the representatives will engage in these transactions or that these transactions, once commenced, will not be discontinued without notice.

Passive Market Making

In connection with this offering, underwriters and selling group members may engage in passive market making transactions in the common stock on the Nasdaq Global Select Market in accordance with Rule 103 of

S-27

Table of Contents

Regulation M under the Exchange Act during a period before the commencement of offers or sales of common stock and extending through the completion of distribution. A passive market maker must display its bid at a price not in excess of the highest independent bid of that security. However, if all independent bids are lowered below the passive market maker’s bid, that bid must then be lowered when specified purchase limits are exceeded. Passive market making may cause the price of our common stock to be higher than the price that otherwise would exist in the open market in the absence of those transactions. The underwriters and dealers are not required to engage in passive market making and may end passive market making activities at any time.

Electronic Distribution

In connection with the offering, certain of the underwriters or securities dealers may distribute prospectuses by electronic means, such as e-mail.

Conflicts of Interest

Affiliates of certain of the underwriters are lenders under our 2015 Credit Facility and may receive a portion of the net proceeds from the offering. Because of the manner in which the proceeds will be used, the offering will be conducted in accordance with FINRA Rule 5121. In accordance with that rule, no “qualified independent underwriter” is required, because a bona fide public market exists in the shares, as that term is defined in the rule.

Other Relationships

Some of the underwriters and their affiliates have engaged in, and may in the future engage in, investment banking and other commercial dealings in the ordinary course of business with us or our affiliates. They have received, or may in the future receive, customary fees and commissions for these transactions.

In addition, in the ordinary course of their business activities, the underwriters and their affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers. Such investments and securities activities may involve securities and/or instruments of ours or our affiliates. The underwriters and their affiliates may also make investment recommendations and/or publish or express independent research views in respect of such securities or financial instruments and may hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.

Notice to Prospective Investors in the European Economic Area

In relation to each member state of the European Economic Area (each, a “Member State”), no offer of shares which are the subject of the offering has been, or will be made to the public in that Member State, other than under the following exemptions under the Prospectus Directive:

provided that no such offer of shares referred to in (a) to (c) above shall result in a requirement for the Company or any Representative to publish a prospectus pursuant to Article 3 of the Prospectus Directive, or supplement a prospectus pursuant to Article 16 of the Prospectus Directive.

S-28

Table of Contents

Each person located in a Member State to whom any offer of shares is made or who receives any communication in respect of an offer of shares, or who initially acquires any shares will be deemed to have represented, warranted, acknowledged and agreed to and with each representative and the Company that (1) it is a “qualified investor” within the meaning of the law in that Member State implementing Article 2(1)(e) of the Prospectus Directive; and (2) in the case of any shares acquired by it as a financial intermediary as that term is used in Article 3(2) of the Prospectus Directive, the shares acquired by it in the offer have not been acquired on behalf of, nor have they been acquired with a view to their offer or resale to, persons in any Member State other than qualified investors, as that term is defined in the Prospectus Directive, or in circumstances in which the prior consent of the representatives has been given to the offer or resale; or where shares have been acquired by it on behalf of persons in any Member State other than qualified investors, the offer of those shares to it is not treated under the Prospectus Directive as having been made to such persons.

The Company, the representatives and their respective affiliates will rely upon the truth and accuracy of the foregoing representations, acknowledgments and agreements.

This prospectus supplement has been prepared on the basis that any offer of shares in any Member State will be made pursuant to an exemption under the Prospectus Directive from the requirement to publish a prospectus for offers of shares. Accordingly any person making or intending to make an offer in that Member State of shares which are the subject of the offering contemplated in this prospectus supplement may only do so in circumstances in which no obligation arises for the Company or any of the representatives to publish a prospectus pursuant to Article 3 of the Prospectus Directive in relation to such offer. Neither the Company nor the representatives have authorized, nor do they authorize, the making of any offer of shares in circumstances in which an obligation arises for the Company or the representatives to publish a prospectus for such offer.

For the purposes of this provision, the expression an “offer of ordinary shares to the public” in relation to any shares in any Member State means the communication in any form and by any means of sufficient information on the terms of the offer and the shares to be offered so as to enable an investor to decide to purchase or subscribe the shares, as the same may be varied in that Member State by any measure implementing the Prospectus Directive in that Member State, the expression “Prospectus Directive” means Directive 2003/71/EC (as amended) and includes any relevant implementing measure in each Member State.

The above selling restriction is in addition to any other selling restrictions set out below.

Notice to Prospective Investors in the United Kingdom

In addition, in the United Kingdom, this document is being distributed only to, and is directed only at, and any offer subsequently made may only be directed at persons who are “qualified investors” (as defined in the Prospectus Directive) (i) who have professional experience in matters relating to investments falling within Article 19 (5) of the Financial Services and Markets Act 2000 (Financial Promotion) Order 2005, as amended (the “Order”) and/or (ii) who are high net worth companies (or persons to whom it may otherwise be lawfully communicated) falling within Article 49(2)(a) to (d) of the Order (all such persons together being referred to as “relevant persons”).

ABOUT THIS PROSPECTUS

This prospectus is part of a registration statement on Form S-3 that we filed with the Securities and Exchange Commission, or the SEC, utilizing a “shelf” registration process. Under this shelf process, we may sell the securities described in this prospectus in one or more offerings. This prospectus provides you with a general description of the securities we may offer. Each time we sell securities, we will provide a prospectus supplement that will contain specific information about the terms of that offering.

You should read both this prospectus and any prospectus supplement together with additional information described under the heading “Where You Can Find More Information.” You should rely only on the information contained in or incorporated by reference in this prospectus and any prospectus supplement. We have not authorized anyone to provide you with information other than the information contained or incorporated by reference in this prospectus or any prospectus supplement. We are not making an offer to sell these securities in any jurisdiction where the offer or sale is not permitted. The information contained in this prospectus speaks only as of the date of this prospectus and the information in the documents incorporated or deemed to be incorporated by reference in this prospectus speaks only as of the respective dates those documents were filed with the SEC. To the extent that any statement that we make in a prospectus supplement is inconsistent with statements made in this prospectus or a document that is incorporated or deemed incorporated by reference in this prospectus, the statements made in this prospectus will be deemed modified or superseded by those made in the applicable prospectus supplement.

In addition, we are a supplier to certain other industrial markets, such as kitchen cabinet, office and household furniture, fixtures and commercial furnishings, marine, and other industrial markets. We manufacture a variety of products including decorative vinyl and paper laminated panels, fabricated aluminum products, wrapped vinyl, paper and hardwood profile mouldings, solid surface, granite, and quartz countertops, cabinet doors and components, hardwood furniture, fiberglass bath and shower fixtures, fiberglass and plastic component products including front and rear caps and marine helms, slide-out trim and fascia, interior passage doors, exterior graphics and RV painting, simulated wood and stone products, and slotwall panels and components, among others.

FORWARD-LOOKING STATEMENTS

Information both included and incorporated by reference in this prospectus and in any prospectus supplement may contain forward-looking statements, concerning, among other things, our outlook, financial projections and business strategies, all of which are subject to risks, uncertainties and assumptions. These forward-looking statements are identified by the use of terms such as “intend,” “plan,” “may,” “should,” “will,” “anticipate,” “believe,” “could,” “estimate,” “expect,” “continue,” “potential,” “opportunity,” “project” and similar terms. These statements are based on certain assumptions and analyses that we believe are appropriate under the circumstances. Should one or more of these risks or uncertainties materialize, or should our assumptions prove incorrect, actual results may differ materially from those indicated in these statements. We cannot guarantee that we will achieve these plans, intentions or expectations. Forward-looking statements speak only as of the date they are made, and we undertake no obligation to publicly update or revise any of them in light of new information, future events or otherwise.

Factors that may impact forward-looking statements include, without limitation, the impact of any economic downturns especially in the residential housing market, a decline in consumer confidence levels, pricing pressures due to competition, costs and availability of raw materials, availability of commercial credit, availability of retail and wholesale financing for residential and manufactured homes, availability and costs of labor, inventory levels of retailers and manufacturers, levels of repossessed residential and manufactured homes, the financial condition of our customers, retention and concentration of significant customers, the ability to generate cash flow or obtain financing to fund growth, the ability to effectively manage the costs and the implementation of the new enterprise resource management system, future growth rates in the Company’s core businesses, the seasonality and cyclicality in the industries to which our products are sold, the successful integration of acquisitions, interest rates, oil and gasoline prices, adverse weather conditions impacting retail sales, and our ability to remain in compliance with our credit agreement covenants. In addition, national and regional economic conditions and consumer confidence may affect the retail sale of recreational vehicles and residential and manufactured homes. We are affected by other factors identified in our filings with the Securities and Exchange Commission, some of which are set forth in the section entitled “Part I, Item 1A. Risk Factors” in our most recent Annual Report on Form 10-K and in “Part II, Item 1A. Risk Factors,” in our quarterly reports on Form 10-Q filed subsequent to such Form 10-K, which are incorporated by reference into this prospectus and any prospectus supplement in their entirety, as the same may be updated from time to time by our future filings under the Exchange Act. Although we have attempted to list these important factors, we also wish to caution investors that other factors may prove to be important in the future in affecting our operating results. New factors emerge from time to time, and it is not possible for us to predict all of these factors, nor can we assess the impact each factor or combination of factors may have on our business.

These risks and uncertainties, along with the risk factors discussed under “Risk Factors” in this prospectus and in any prospectus supplement, should be considered in evaluating any forward-looking statements contained or incorporated by reference in this prospectus or in any prospectus supplement. All forward-looking statements speak only as of the date they are made. All subsequent written and oral forward-looking statements attributable to us or any person acting on our behalf are qualified by the cautionary statements in this section.

DESCRIPTION OF DEBT SECURITIES

The following description, together with the additional information we include in any applicable prospectus supplement, summarizes the material terms and provisions of the debt securities that we may offer under this prospectus. The debt securities will be our direct general obligations and may include debentures, notes, bonds or other evidences of indebtedness. The debt securities will be either senior debt securities or subordinated debt securities. The debt securities will be issued under one or more separate indentures. Senior debt securities will be issued under a senior debt indenture, and subordinated debt securities will be issued under a subordinated debt indenture. We use the term “indentures” to refer to both the senior indenture and the subordinated indenture. A form of each of the senior indenture and the subordinated indenture is filed as an exhibit to the registration statement of which this prospectus is a part. The indentures will be qualified under the Trust Indenture Act. We use the term “indenture trustee” to refer to either the senior trustee or the subordinated trustee, as applicable.

The following summaries of material provisions of the debt securities and indentures are subject to, and qualified in their entirety by reference to, all the provisions of the indenture applicable to a particular series of debt securities and the description thereof contained in the prospectus supplement.

General

We will describe in each prospectus supplement the following terms relating to a series of debt securities:

Table of Contents

Conversion or Exchange Rights

We will set forth in the prospectus supplement the terms on which a series of debt securities may be convertible into or exchangeable for common stock or other securities. We will include provisions as to whether conversion or exchange is mandatory, at the option of the holder or at our option. We may include provisions pursuant to which the number of shares of common stock or other securities that the holders of the series of debt securities receive would be subject to adjustment.

Consolidation, Merger or Sale

The indentures will not contain any covenant which restricts our ability to merge or consolidate, or sell, convey, transfer or otherwise dispose of all or substantially all of our assets. However, any successor to or acquirer of our assets must assume all of our obligations under the indentures or the debt securities, as appropriate.

Events of Default Under the Indenture

The following may be events of default under the indentures with respect to any series of debt securities that we may issue:

Table of Contents

If an event of default with respect to debt securities of any series occurs and is continuing, the indenture trustee or the holders of at least 25% in aggregate principal amount of the outstanding debt securities of that series, by notice to us in writing, and to the indenture trustee if notice is given by such holders, may declare the unpaid principal, premium, if any, and accrued interest, if any, due and payable immediately; provided that if an event of bankruptcy, insolvency or reorganization occurs, such amounts shall automatically become due and payable without any declaration or other action on the part of the trustee or any holder.

The holders of a majority in principal amount of the outstanding debt securities of an affected series may waive any default or event of default with respect to the series and its consequences, except defaults or events of default regarding payment of principal, premium, if any, or interest, unless we have cured the default or event of default in accordance with the indenture. Any waiver will cure the default or event of default.

Subject to the terms of the indentures, if an event of default under an indenture occurs and is continuing, the indenture trustee will be under no obligation to exercise any of its rights or powers under such indenture at the request or direction of any of the holders of the applicable series of debt securities, unless such holders have offered the indenture trustee reasonable indemnity. The holders of a majority in principal amount of the outstanding debt securities of any series will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the indenture trustee, or exercising any trust or power conferred on the indenture trustee, with respect to the debt securities of that series, provided that:

A holder of the debt securities of any series will only have the right to institute a proceeding under the indentures or to appoint a receiver or trustee, or to seek other remedies if:

These limitations do not apply to a suit instituted by a holder of debt securities if we default in the payment of the principal, premium, if any, or interest on, the debt securities.

Table of Contents

We will periodically file statements with the indenture trustee regarding our compliance with specified covenants in the indentures.

Modification of Indenture; Waiver

We and the indenture trustee may change an indenture without the consent of any holders with respect to specific matters, including:

In addition, under the indentures, the rights of holders of a series of debt securities may be changed by us and the indenture trustee with the written consent of the holders of at least a majority in aggregate principal amount of the outstanding debt securities of each series that is affected. However, we and the indenture trustee may only make the following changes with the consent of each holder of any outstanding debt securities affected:

Discharge

Each indenture provides that we can elect to be discharged from our obligations with respect to one or more series of debt securities, except for obligations to:

In order to exercise our rights to be discharged, we must deposit with the indenture trustee money or government obligations sufficient to pay all the principal of, any premium, if any, and interest on, the debt securities of the series on the dates payments are due.

multiple thereof. The indentures provide that we may issue debt securities of a series in temporary or permanent global form and as book-entry securities that will be deposited with, or on behalf of, The Depositary Trust Company or another Depositary named by us and identified in a prospectus supplement with respect to that series. See “Book-Entry Issuance” for a further description of the terms relating to any book-entry securities.

Subject to the terms of the indentures and the limitations applicable to global securities described in the applicable prospectus supplement, the holder of the debt securities of any series, at its option, can exchange the debt securities for other debt securities of the same series, in any authorized denomination and of like tenor and aggregate principal amount.

Subject to the terms of the indentures and the limitations applicable to global securities set forth in the applicable prospectus supplement, holders of the debt securities may present the debt securities for exchange or for registration of transfer, duly endorsed or with the form of transfer endorsed thereon duly executed if so required by us or the security registrar, at the office of the security registrar or at the office of any transfer agent designated by us for this purpose. Unless otherwise provided in the debt securities that the holder presents for transfer or exchange, no service charge will be required for any registration of transfer or exchange, but we may require payment of any taxes or other governmental charges.

We will name in the applicable prospectus supplement the security registrar, and any transfer agent in addition to the security registrar, that we initially designate for any debt securities. We may at any time designate additional transfer agents or rescind the designation of any transfer agent or approve a change in the office through which any transfer agent acts, except that we will be required to maintain a transfer agent in each place of payment for the debt securities of each series.

If we elect to redeem the debt securities of any series, we will not be required to:

Payment and Paying Agents

Unless we otherwise indicate in the applicable prospectus supplement, we will make payment of the interest on any debt securities on any interest payment date to the person in whose name the debt securities, or one or more predecessor securities, are registered at the close of business on the regular record date for the interest.

We will pay principal of and any premium and interest on the debt securities of a particular series at the office of the paying agents designated by us, except that unless we otherwise indicate in the applicable prospectus supplement, we will make interest payments by check which we will mail to the holder. Unless we otherwise indicate in a prospectus supplement, we will designate the corporate trust office of the indenture trustee in the City of New York as our sole paying agent for payments with respect to debt securities of each series. We will name in the applicable prospectus supplement any other paying agents that we initially designate for the debt securities of a particular series. We will maintain a paying agent in each place of payment for the debt securities of a particular series.

All money we pay to a paying agent or the indenture trustee for the payment of the principal of or any premium or interest on any debt securities which remains unclaimed at the end of two years after such principal, premium or interest has become due and payable will be repaid to us, and the holder of the security thereafter may look only to us for payment thereof.

Table of Contents

Governing Law

The indentures and the debt securities will be governed by and construed in accordance with the laws of the State of New York, except to the extent that the Trust Indenture Act is applicable.

Subordination of Subordinated Notes

The subordinated notes will be unsecured and will be subordinate and junior in priority of payment to certain of our other indebtedness to the extent described in a prospectus supplement. The subordinated indenture does not limit the amount of subordinated notes which we may issue. It also does not limit us from issuing any other secured or unsecured debt.

Regarding the Indenture Trustee

We will name the indenture trustee for debt securities issued under the applicable indenture in the applicable supplement to this prospectus and, unless otherwise indicated in a prospectus supplement, the indenture trustee will also act as Transfer Agent and Paying Agent with respect to the debt securities. The indenture trustee may be removed at any time with respect to the debt securities of any series by act of the holders of a majority in principal amount of the outstanding debt securities of such series delivered to the indenture trustee and to us.

DESCRIPTION OF COMMON STOCK AND PREFERRED STOCK

General

We are currently authorized to issue 20,000,000 shares of common stock, without par value, and 1,000,000 shares of preferred stock, without par value. Each share of our common stock has the same relative rights as, and is identical in all respects to, each other share of our common stock. On June 5, 2015, there were approximately 15,451,900 shares of our common stock outstanding. There are no shares of preferred stock outstanding.

Common Stock

Issuance of Common Stock. Shares of common stock may be issued from time to time as our board shall determine and on such terms and for such consideration as shall be fixed by the board. The authorized number of shares of common stock may, without a class or series vote, be increased or decreased from time to time by the affirmative vote of the holders of a majority of the stock of the Company entitled to vote.

Dividends and Rights Upon Liquidation. After the requirements with respect to preferential dividends on preferred stock, if any, are met, the holders of our outstanding common stock are entitled to receive dividends out of assets legally available at the time and in the amounts as the board may from time to time determine. Our common stock is not convertible or exchangeable into other securities. Upon our liquidation, dissolution or winding up, the holders of our common stock are entitled to receive the assets that are legally available for distribution on a pro rata basis, after payment of all of our debts and other liabilities and subject to the prior rights of holders of any preferred stock then outstanding. The Company does not currently pay a dividend on its common stock.

Voting Rights. The holders of the common stock are entitled to vote at all meetings of the shareholders and are entitled to cast one vote for each share of common stock held by them respectively and standing in their respective names on the books of the Company.

Preemptive Rights. Holders of our common stock do not have preemptive rights with respect to any shares that may be issued. Shares of our common stock are not subject to redemption.

Relevant Provisions of the Indiana Business Corporation Law

The Indiana Business Corporation Law (the “IBCL”) limits some transactions between an Indiana company and any person who acquires 10% or more of the company’s common stock (an “interested shareholder”). During the five-year period after the acquisition of 10% or more of a company’s common stock, an interested shareholder cannot enter into a business combination with the company unless, before the interested shareholder acquired the common stock, the board of directors of the company approved the acquisition of common stock or approved the business combination. After the five-year period, an interested shareholder can enter into only the following three types of business combinations with the company: (i) a business combination approved by the board of directors of the company before the interested shareholder acquired the common stock; (ii) a business combination approved by holders of a majority of the common stock not owned by the interested shareholder; and (iii) a business combination in which the shareholders receive a price for their common stock at least equal to a formula price based on the highest price per common share paid by the interested shareholder.

In addition, under Indiana law, a person who acquires shares giving that person more than 20%, 33 1/3%, and 50% of the outstanding voting securities of an Indiana corporation is subject to the “Control Share Acquisitions Statute” of the IBCL and may lose the right to vote the shares which take the acquiror over these respective levels of ownership. Before an acquiror may vote the shares that take the acquiror over these ownership thresholds, the acquiror must obtain the approval of a majority of the shares of each class or series of

10

Table of Contents

shares entitled to vote separately on the proposal, excluding shares held by officers of the corporation, by employees of the corporation who are directors of the corporation and by the acquiror. An Indiana corporation subject to the Control Share Acquisitions Statute may elect not to be covered by the statute by so providing in its articles of incorporation or by-laws. We have adopted a provision in our Amended and Restated By-laws which states that the Control Share Acquisitions Statute shall not apply to the issued and outstanding shares of our common stock. We opted out of the Control Share Acquisitions Statute when we sold shares of our common stock in connection with the acquisition of Adorn Holdings, Inc. in 2007.

The following description, together with the additional information we include in any applicable prospectus supplement, summarizes the material terms and provisions of the depositary shares that we may offer under this prospectus. The following statements with respect to the depositary shares and depositary receipts are summaries of, and subject to, the detailed provisions of a deposit agreement to be entered into by Patrick and a depositary to be selected at the time of issue (the “depositary”) and the form of depositary receipt. The form of deposit agreement and the form of depositary receipt will be filed with the SEC.

General

We may, at our option, elect to issue fractional shares of preferred stock, rather than full shares of preferred stock. In the event such option is exercised, we may elect to have a depositary issue receipts for depositary shares, each receipt representing a fraction, to be set forth in the prospectus supplement relating to a particular series of preferred stock, of a share of a particular series of preferred stock as described below.

The shares of any series of preferred stock represented by depositary shares will be deposited under a deposit agreement between us and a bank or trust company that we select. Subject to the terms of the deposit agreement, each owner of a depositary share will be entitled, in proportion to the applicable fraction of a share of preferred stock represented by such depositary share, to all the rights and preferences of the preferred stock represented by the depositary share, including dividend, voting, redemption and liquidation rights.

Depositary Receipts

The depositary shares will be evidenced by depositary receipts issued pursuant to the deposit agreement. Depositary receipts will be distributed to those persons purchasing the fractional shares of preferred stock in accordance with the terms of an offering of the preferred stock.

Withdrawal of Preferred Stock

Upon surrender of depositary receipts at the office of the depositary and upon payment of the charges provided in the deposit agreement, a holder of depositary receipts may have the depositary deliver to the holder the whole shares of preferred stock relating to the surrendered depositary receipts. Holders of depositary shares may receive whole shares of the related series of preferred stock on the basis set forth in the related prospectus supplement for such series of preferred stock, but holders of such whole shares will not after the exchange be entitled to receive depositary shares for their whole shares. If the depositary receipts delivered by the holder evidence a number of depositary shares in excess of the number of depositary shares representing the number of whole shares of the related series of preferred stock to be withdrawn, the depositary will deliver to the holder at the same time a new depositary receipt evidencing such excess number of depositary shares.

Dividends and Other Distributions

The depositary will distribute all cash dividends or other cash distributions received for the preferred stock to the record holders of depositary shares relating to the preferred stock in proportion to the numbers of such depositary shares owned by such holders.

In the event of a distribution other than in cash, the depositary will distribute property received by it to the record holders of depositary shares entitled thereto, unless the depositary determines that it is not feasible to make distribution of the property. In that case the depositary may, with our approval, sell such property and distribute the net proceeds from the sale to such holders.

Redemption of Depositary Shares

If a series of preferred stock represented by depositary shares is subject to redemption, the depositary shares will be redeemed from the proceeds received by the depositary resulting from the redemption, in whole or in part, of the series of preferred stock held by the depositary. The redemption price per depositary share will be equal to the applicable fraction of the redemption price per share payable with respect to the series of the preferred stock. Whenever we redeem shares of preferred stock held by the depositary, the depositary will redeem as of the same redemption date the number of depositary shares representing shares of preferred stock redeemed by us. If less than all the depositary shares are to be redeemed, the depositary shares to be redeemed will be selected by lot or pro rata as may be determined by the depositary.

Voting the Preferred Stock

Upon receipt of notice of any meeting at which the holders of the preferred stock are entitled to vote, the depositary will mail the information contained in such notice of meeting to the record holders of the depositary shares relating to such preferred stock. Each record holder of such depositary shares on the record date, which will be the same date as the record date for the preferred stock, will be entitled to instruct the depositary as to the exercise of the voting rights pertaining to the amount of the preferred stock represented by such holder’s depositary shares. The depositary will endeavor, insofar as practicable, to vote the amount of the preferred stock represented by such depositary shares in accordance with such instructions, and we will agree to take all action which may be deemed necessary by the depositary in order to enable the depositary to do so. The depositary will not vote the preferred stock to the extent it does not receive specific instructions from the holders of depositary shares representing such preferred stock.

Amendment and Termination of the Deposit Agreement

We and the depositary at any time may amend the form of depositary receipt evidencing the depositary shares and any provision of the deposit agreement. However, any amendment which materially and adversely alters the rights of the holders of depositary shares will not be effective unless such amendment has been approved by the holders of at least a majority of the depositary shares then outstanding. We or the depositary may terminate the deposit agreement only if all outstanding depositary shares have been redeemed, or there has been a final distribution in respect of the preferred stock in connection with any liquidation, dissolution or winding up of the Company and such distribution has been distributed to the holders of depositary receipts.

Charges of Depositary

We will pay all transfer and other taxes and governmental charges arising solely from the existence of the depositary arrangements. We will pay charges of the depositary in connection with the initial deposit of the preferred stock and any redemption of the preferred stock. Holders of depositary receipts will pay other transfer and other taxes and governmental charges and such other charges as are expressly provided in the deposit agreement to be for their accounts.

Miscellaneous

The depositary will forward to the record holders of the depositary shares relating to such preferred stock all reports and communications from us which are delivered to the depositary.

Neither we nor the depositary will be liable if either one is prevented or delayed by law or any circumstance beyond their control in performing the obligations under the deposit agreement. The obligations of Patrick and the depositary under the deposit agreement will be limited to performance in good faith of their duties thereunder, and they will not be obligated to prosecute or defend any legal proceeding in respect of any depositary shares or preferred stock unless satisfactory indemnity is furnished. The depositary may rely upon

written advice of counsel or accountants, or information provided by persons presenting preferred stock for deposit, holders of depositary receipts or other persons believed to be competent and on documents believed to be genuine.

Resignation and Removal of Depositary

The depositary may resign at any time by delivering to us notice of its election to do so, and we may at any time remove the depositary, any such resignation or removal to take effect upon the appointment of a successor depositary and its acceptance of such appointment. Such successor depositary must be appointed within 60 days after delivery of the notice of resignation or removal.

DESCRIPTION OF STOCK PURCHASE CONTRACTS AND STOCK PURCHASE UNITS

We may issue stock purchase contracts, representing contracts obligating holders to purchase from us, and we may sell to the holders, a specified number of shares of common stock at a future date or dates. The price per share of common stock may be fixed at the time the stock purchase contracts are issued or may be determined by reference to a specific formula set forth in the stock purchase contracts. Stock purchase contracts may be issued separately or as a part of units (“stock purchase units”) consisting of a stock purchase contract and either (i) senior debt securities or subordinated debt securities or (ii) debt obligations of third parties, including U.S. Treasury securities, securing the holder’s obligations to purchase the common stock under the stock purchase contracts. The stock purchase contracts may require us to make periodic payments to the holders of the stock purchase units or vice versa, and such payments may be unsecured or prefunded on some basis. The stock purchase contracts may require holders to secure their obligations thereunder in a specified manner, and in certain circumstances we may deliver newly issued prepaid stock purchase contracts (“prepaid securities”) upon release to a holder of any collateral securing such holder’s obligations under the original stock purchase contract.

The applicable prospectus supplement will describe the terms of any stock purchase contracts or stock purchase units and, if applicable, prepaid securities. Certain material United States Federal income tax considerations applicable to the stock purchase units and stock purchase contracts will be set forth in the prospectus supplement relating thereto.

DESCRIPTION OF UNITS

We may issue units under one or more unit agreements, each referred to as a unit agreement, to be entered into between us and a third party, as unit agent. The unit agent will act solely as our agent in connection with the units governed by the unit agreement and will not assume any obligation or relationship of agency or trust for or with any holders of units or interests in those units. We may issue units comprising one or more of the securities described in this prospectus in any combination. Each unit will be issued so that the holder of the unit also is the holder of each security included in the unit. Thus, the holder of a unit will have the rights and obligations of a holder of each included security. The unit agreement under which a unit is issued may provide that the securities included in the unit may not be held or transferred separately at any time or at any time before a specified date.

The applicable prospectus supplement relating to the units we may offer will include specific terms relating to the offering, including, among others: the designation and terms of the units and of the securities comprising the units, and whether and under what circumstances those securities may be held or transferred separately; any provision for the issuance, payment, settlement, transfer or exchange of the units or of the securities comprising those units; and whether the units will be issued in fully registered or global form.

The description in the applicable prospectus supplement and other offering material of any units we offer will not necessarily be complete and will be qualified in its entirety by reference to the applicable unit agreement and unit certificate, which will be filed with the SEC if we offer units.

BOOK-ENTRY ISSUANCE

Unless otherwise indicated in a prospectus supplement, the debt securities of a series offered by us will be issued in the form of one or more fully registered global securities. We anticipate that these global securities will be deposited with, or on behalf of, The Depository Trust Company (“DTC”), which will act as depository, and registered in the name of its nominee. Except as described below, the global securities may be transferred, in whole and not in part, only to DTC or to another nominee of DTC.

DTC has advised us that it is:

DTC was created to hold securities for institutions that have accounts with DTC (“participants”) and to facilitate the clearance and settlement of securities transactions among its participants through electronic book-entry changes in participants’ accounts. Participants include securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations, some of whom (and/or their representatives) own DTC. Access to DTC’s book-entry system is also available to others that clear through or maintain a custodial relationship with a participant, either directly or indirectly. DTC administers its book-entry system in accordance with its rules and bylaws and legal requirements.

Upon issuance of a global security representing offered securities, DTC will credit on its book-entry registration and transfer system the principal amount to participants’ accounts. Ownership of beneficial interests in the global security will be limited to participants or to persons that hold interests through participants. Ownership of interests in the global security will be shown on, and the transfer of those ownership interests will be effected only through, records maintained by DTC (with respect to participants’ interests) and the participants (with respect to the owners of beneficial interests in the global security). The laws of some jurisdictions may require that certain purchasers of securities take physical delivery of those securities in definitive form. These limits and laws may impair the ability to transfer beneficial interests in a global security.

So long as DTC (or its nominee) is the registered holder and owner of a global security, DTC (or its nominee) will be considered, for all purposes under the applicable indenture, the sole owner and holder of the related offered securities. Except as described below, owners of beneficial interests in a global security will not:

Purchases of securities under the DTC system must be made by or through direct participants, which will receive a credit for the securities on DTC’s records. The ownership interest of each actual purchaser of each global security (“beneficial owner”) is in turn recorded on the direct and indirect participants’ records. A beneficial owner does not receive written confirmation from DTC of its purchase, but is expected to receive a written confirmation providing details of the transaction, as well as periodic statements of its holdings, from the direct or indirect participants through which such beneficial owner entered into the action. Transfers of

16

Table of Contents

ownership interests in securities are accomplished by entries made on the books of participants acting on behalf of beneficial owners. Beneficial owners do not receive certificates representing their ownership interests in securities, except in the event that use of the book-entry system for the securities is discontinued.

To facilitate subsequent transfers, the securities are registered in the name of DTC’s partnership nominee, Cede & Co. The deposit of the securities with DTC and their registration in the name of Cede & Co. will effect no change in beneficial ownership. DTC has no knowledge of the actual beneficial owners of the securities; DTC records reflect only the identity of the direct participants to whose accounts securities are credited, which may or may not be the beneficial owners. The participants remain responsible for keeping account of their holdings on behalf of their customers.

Delivery of notice and other communications by DTC to direct participants, by direct participants to indirect participants, and by direct participants and indirect participants to beneficial owners are governed by arrangements among them, subject to any statutory or regulatory requirements as may be in effect from time to time.

Neither DTC nor Cede & Co. consents or votes with respect to the securities. Under its usual procedures, DTC mails a proxy (an “Omnibus Proxy”) to the issuer as soon as possible after the record date. The Omnibus Proxy assigns Cede & Co.’s consenting or voting rights to those direct participants to whose accounts the securities are credited on the record date (identified on a list attached to the Omnibus Proxy).

Redemption proceeds, distributions and dividend payments, if any, on the securities will be made to DTC. DTC’s practice is to credit direct participants’ accounts on the payment date in accordance with their respective holdings as shown on DTC’s records, unless DTC has reason to believe that it will not receive payment on the payment date. Payments by participants to beneficial owners are governed by standing instructions and customary practices, as is the case with securities held for the accounts of customers in bearer form or registered in “street name,” and are the responsibility of such participant and not of DTC, the trustee or us, subject to any statutory or regulatory requirements as may be in effect from time to time. Payment of principal and interest, if any, to DTC is our or the trustee’s responsibility, disbursement of such payments to direct participants is DTC’s responsibility, and disbursement of such payments to the beneficial owners is the responsibility of direct and indirect participants.

DTC may discontinue providing its services as securities depository with respect to the securities at any time by giving reasonable notice to us or, if applicable, the trustee. Under such circumstances, in the event that a successor securities depository is not appointed, debt security certificates are required to be printed and delivered.

We may decide to discontinue use of the system of book-entry transfers through DTC or a successor securities depository. In that event, debt security certificates will be printed and delivered.

We have obtained the information in this section concerning DTC and DTC’s book-entry system from sources that we believe to be reliable, but we take no responsibility for the accuracy of this information.

None of us, any underwriter or agent, the trustee or any applicable paying agent will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial interests in a global security, or for maintaining, supervising or reviewing any records relating to such beneficial interest.

Underwriters and agents may engage in transactions with, or perform services for the Company and its affiliates in the ordinary course of business.

In compliance with the guidelines of the Financial Industry Regulatory Authority (“FINRA”), the aggregate maximum discount, commission or agency fees or other items constituting underwriting compensation to be received by any FINRA member or independent broker-dealer will not exceed 8% of any offering pursuant to this prospectus and any applicable prospectus supplement, as the case may be.
