RISK FACTORS

Investing in our common stock involves a high degree of risk. Before you make your investment decision, you should carefully consider the risks described below and the other information contained in this prospectus, including our consolidated financial statements and the related notes. If any of the following risks actually occur, our business, financial condition, results of operations and cash flows could be materially adversely affected. In these circumstances, the market price of our common stock could decline, and you may lose all or part of your investment.

Risks Relating to Our Business

Fluctuations in the price and availability of resins, our principal raw materials, and our inability to obtain adequate supplies of resins from suppliers and pass on resin price increases to customers could adversely affect our business, financial condition, results of operations and cash flows.

The principal raw materials that we use in our high performance thermoplastic corrugated pipe and Allied Products are virgin and recycled resins. Our ability to operate profitably depends, to a large extent, on the markets for these resins. In particular, as resins are derived either directly or indirectly from crude oil derivatives and natural gas liquids, resin prices fluctuate substantially as a result of changes in crude oil and natural gas prices, changes in existing refining capabilities and the capacity of resin suppliers. The petrochemical industry historically has been cyclical and volatile. The cycles are generally characterized by periods of tight supply, followed by periods of oversupply, primarily resulting from significant capacity additions. For example, resin prices have increased since 2010 due to increased demand in the broader economy. The weighted average market cost for the types of resin that we use increased by approximately 0.9% and 6.7% for fiscal years 2013 and 2014, respectively. Unanticipated changes in and disruptions to existing refining capacities could also significantly increase resin prices, often within a short period of time, even if crude oil and natural gas prices remain low.

Our ability to offer our core products depends on our ability to obtain adequate resins, which we purchase directly from major petrochemical and chemical suppliers. We have long-standing relationships as well as supply contracts with some of these suppliers but we have no fixed-price contracts with any of our major suppliers. Prices are typically negotiated on a continuous basis. We have implemented a limited resin price hedging program which has historically covered less than 50% of our virgin resin purchases. The loss of, or substantial decrease in the availability of, raw materials from our suppliers, or the failure by our suppliers to continue to provide us with raw materials on commercially reasonable terms, or at all, could adversely affect our business, financial condition, results of operations and cash flows. In addition, supply interruptions could arise from labor disputes or weather conditions affecting supplies or shipments, transportation disruptions or other factors beyond our control. A disruption in the timely availability of raw materials from our key suppliers would result in a decrease in our revenues and profitability.

Our ability to maintain profitability heavily depends on our ability to pass through to our customers the full amount of any increase in raw material costs, which are a large portion of our overall product costs. We may be unable to do so in a timely manner, or at all, due to competition in the markets in which we operate. In addition, certain of our largest customers historically have exerted significant pressure on their outside suppliers to keep prices low because of their market share. If increases in the cost of raw materials cannot be passed on to our customers, or the duration of time associated with a pass through becomes extended, our business, financial condition, results of operations and cash flows will be adversely affected.

Any disruption or volatility in general business and economic conditions in the markets in which we operate could have a material adverse effect on the demand for our products and services.

The markets in which we operate are sensitive to general business and economic conditions in the United States and worldwide, including availability of credit, interest rates, fluctuation in capital and business and consumer confidence. The capital and credit markets have in recent years been experiencing significant volatility

and disruption. These conditions, combined with price fluctuations in crude oil derivatives and natural gas liquids, declining business and consumer confidence and increased unemployment, precipitated an economic slowdown and severe recession in recent years. The difficult conditions in these markets and the overall economy affect our business in a number of ways. For example:

All of our markets are sensitive to changes in the broader economy. Downturns or lack of substantial improvement in the economy in any region in which we operate have adversely affected and could continue to adversely affect our business, financial condition and results of operations. While we operate in many markets, our business is particularly impacted by changes in the economies of the United States, Canada and Mexico, which represented approximately 87.5%, 4.9% and 5.9%, respectively, of our net sales for fiscal year 2014 and collectively represented approximately 98.3% of our net sales for fiscal year 2014.

We cannot predict the duration of current economic conditions, or the timing or strength of any future recovery of activities in our markets. Continued weakness in the market in which we operate could have a material adverse effect on our business, financial condition, results of operations and cash flows. We may have to close under-performing facilities from time to time as warranted by general economic conditions and/or weakness in the markets in which we operate. In addition to a reduction in demand for our products, these factors may also reduce the price we are able to charge for our products and restrict our ability to pass raw material cost increases to our customers. This, combined with an increase in excess capacity, will negatively impact our profitability, cash flows and our financial condition, generally.

Demand for our products and services could decrease if we are unable to compete effectively, and our success depends largely on our ability to convert current demand for competitive products into demand for our products.

We compete with both manufacturers of high performance thermoplastic corrugated pipe and manufacturers of alternative products, such as concrete, steel and PVC pipe products, on the basis of a number of considerations, including product characteristics such as durability, design, ease of installation, price on a price-to-value basis and service. In particular, we compete on a global, national and local basis with pipe products made of traditional materials which our high performance thermoplastic corrugated pipe products are designed to replace. For example, our N-12 and SaniTite HP products face competition from concrete, steel and PVC pipe products in the small- and large-diameter size segments of the market.

Our ability to successfully compete and grow depends largely on our ability to continue to convert the current demand for concrete, steel and PVC pipe products into demand for our high performance thermoplastic corrugated pipe and Allied Products. Our thermoplastic pipe typically has an installed cost advantage of approximately 20% over concrete pipe. However, depending upon certain factors such as the size of the pipe, the geography of a particular location and then-existing raw material costs, the initial cost of our thermoplastic pipe may be higher than the initial cost of alternative products such as concrete, steel and PVC pipe products. To increase our market share, we will need to increase material conversion by educating our customers about the value of our products in comparison to existing alternatives, particularly on an installed cost basis, working with government agencies to expand approvals for our products and working with civil engineering firms which may influence the specification of our products on construction projects. No assurance can be given that our efforts to increase or maintain the current rate of material conversion will be successful, and our failure to do so would have a material adverse effect on our business, financial condition, results of operations and cash flows.

We also expect that new competitors may develop over time. No assurance can be given that we will be able to respond effectively to such competitive pressures. Increased competition by existing and future competitors could result in reductions in sales, prices, volumes and gross margins that would materially adversely affect our business, financial condition, results of operations and cash flows. Furthermore, our success will depend, in part, on our ability to maintain our market share and gain market share from competitors.

Certain of our competitors have financial and other resources that are greater than ours and may be better able to withstand price competition, especially with respect to traditional products. In addition, consolidation by industry participants could result in competitors with increased market share, larger customer bases, greater diversified product offerings and greater technological and marketing expertise, which would allow them to compete more effectively against us. Moreover, our competitors may develop products that are superior to our products or may adapt more quickly to new technologies or evolving customer requirements. Technological advances by our competitors may lead to new manufacturing techniques and make it more difficult for us to compete. In many markets in which we operate there are no significant entry barriers that would prevent new competitors from entering the market, especially on the local level, or existing competitors from expanding in the market. In addition, because we do not have long-term arrangements with many of our customers, these competitive factors could cause our customers to cease purchasing our products.

In addition, our contracts with municipalities are often awarded and renewed through periodic competitive bidding. We may not be successful in obtaining or renewing these contracts on financially attractive terms or at all, which could adversely affect our business, financial condition, results of operations and cash flows.

Our results of operations could be adversely affected by the effects of weather.

Although weather patterns affect our operating results throughout the year, adverse weather historically has reduced construction activity in our third and fourth fiscal quarters. In contrast, our highest volume of net sales historically has occurred in our first and second fiscal quarters.

Most of our business units experience seasonal variation as a result of the dependence of our customers on suitable weather to engage in construction projects. Generally, during the winter months, construction activity

- 20 -

Table of Contents

declines due to inclement weather, frozen ground and shorter daylight hours. For example, during the spring of 2013 and 2014, the extremely cold weather significantly reduced the level of construction activities in the United States, thereby impacting our revenues. In addition, to the extent that hurricanes, severe storms, floods, other natural disasters or similar events occur in the geographic regions in which we operate, our results of operations may be adversely affected. For example, Hurricane Andrew in Florida in 1992 and the extensive flooding of the Mississippi River in 2011 resulted in temporary interruption in business activity in these areas. We anticipate that fluctuations of our operation results from period to period due to seasonality will continue in the future.

The loss of any of our significant customers could adversely affect our business, financial condition, results of operations and cash flows.

Our 10 largest customers in the United States generated approximately 46.7% of our domestic net sales in fiscal year 2014. We cannot guarantee that we will maintain or improve our relationships with these customers or that we will continue to supply these customers at historical levels. Because we do not have long-term arrangements with many of our customers, such customers may cease purchasing our products without notice or upon short notice to us. During the economic downturn, some of our customers reduced their operations. For example, some homebuilder customers exited or severely curtailed building activity in certain of our markets. There is no assurance that our customers will increase their activity level or return it to historic levels. A slow economic recovery could continue to have material adverse effect on our business, financial condition, results of operations and cash flows.

In addition, consolidation among customers could also result in a loss of some of our present customers to our competitors. The loss of one or more of our significant customers, a significant customer’s decision to purchase our products in significantly lower quantities than they have in the past, or deterioration in our relationship with any of them could have a material adverse effect on our business, financial condition, results of operations and cash flows.

The majority of our net sales are credit sales which are made primarily to customers whose ability to pay is dependent, in part, upon the economic strength of the industry and geographic areas in which they operate, and the failure to collect monies owed from customers could adversely affect our financial condition.

The majority of our net sales volume is facilitated through the extension of credit to our customers whose ability to pay is dependent, in part, upon the economic strength of the industry in the areas where they operate. Our business units offer credit to customers, either through unsecured credit that is based solely upon the creditworthiness of the customer, or secured credit for materials sold for a specific job where the security lies in lien rights associated with the material going into the job. The type of credit offered depends both on the financial strength of the customer and the nature of the business in which the customer is involved. End users, resellers and other non-contractor customers generally purchase more on unsecured credit than secured credit. The inability of our customers to pay off their credit lines in a timely manner, or at all, would adversely affect our business, financial condition, results of operations and cash flows. Furthermore, our collections efforts with respect to non-paying or slow-paying customers could negatively impact our customer relations going forward.

Because we depend on the creditworthiness of certain of our customers, if the financial condition of our customers declines, our credit risk could increase. Significant contraction in our markets, coupled with tightened credit availability and financial institution underwriting standards, could adversely affect certain of our customers. Should one or more of our larger customers declare bankruptcy, it could adversely affect the collectability of our accounts receivable, bad debt reserves and net income.

Our international operations expose us to political, economic and regulatory risks not normally faced by businesses that operate only in the United States.

International operations are exposed to different political, economic and regulatory risks that are not faced by businesses that operate solely in the United States. Some of our operations are outside the United States, with

- 21 -

Table of Contents

manufacturing and distribution facilities in Canada and several Latin American countries. Our international operations are subject to risks similar to those affecting our operations in the United States in addition to a number of other risks, including:

As a result of our international operations we could be adversely affected by violations of the U.S. Foreign Corrupt Practices Act and similar foreign anti-corruption laws.

The U.S. Foreign Corrupt Practices Act, or the FCPA, and similar foreign anti-corruption laws generally prohibit companies and their intermediaries from making improper payments or providing anything of value to influence foreign government officials for the purpose of obtaining or retaining business or obtaining an unfair advantage. Recent years have seen a substantial increase in the global enforcement of anti-corruption laws, with more frequent voluntary self-disclosures by companies, aggressive investigations and enforcement proceedings by both the U.S. Department of Justice and the U.S. Securities and Exchange Commission, or SEC, resulting in record fines and penalties, increased enforcement activity by non-U.S. regulators, and increases in criminal and civil proceedings brought against companies and individuals.

We have operations in Canada as well as existing joint ventures in Mexico, Central America and South America. Our internal policies provide for compliance with all applicable anti-corruption laws for both us and for our joint venture operations. Our continued operation and expansion outside the United States, including in developing countries, could increase the risk of such violations in the future. Despite our training and compliance programs, we cannot assure you that our internal control policies and procedures always will protect us from unauthorized reckless or criminal acts committed by our employees, agents or joint venture partners. In the event that we believe or have reason to believe that our employees, agents or joint venture partners have or may have violated applicable anti-corruption laws, including the FCPA, we may be required to investigate or have outside counsel investigate the relevant facts and circumstances, which can be expensive and require significant time and attention from senior management. Violations of these laws may result in severe criminal or civil sanctions, which could disrupt our business and result in a material adverse effect on our reputation, financial condition, results of operations and cash flows.

Conducting a portion of our operations through joint ventures exposes us to risks and uncertainties, many of which are outside of our control.

With respect to our existing joint ventures in Mexico, Central America and South America, any differences in views among the joint venture participants may result in delayed decisions or in failures to agree on major issues. We also cannot control the actions of our joint venture partners, including any nonperformance, default or bankruptcy of our joint venture partners. As a result, we may be unable to control the quality of products

- 22 -

Table of Contents

produced by the joint ventures or achieve consistency of product quality as compared with our other operations. In addition to net sales and market share, this may have a material negative impact on our brand and how it is perceived thereafter. Moreover, if our partners also fail to invest in the joint venture in the manner that is anticipated or otherwise fail to meet their contractual obligations, the joint ventures may be unable to adequately perform and conduct their respective operations, requiring us to make additional investments or perform additional services to ensure the adequate performance and delivery of products and/or services to the joint ventures’ customers, which could have a material adverse effect on our business, financial condition, results of operations and cash flows.

We may not be able to successfully expand into new product markets.

We may expand into new product markets based on our existing manufacturing, design and engineering capabilities and services. Our business depends in part on our ability to identify future products and product lines that complement existing products and product lines and that respond to our customers’ needs. We may not be able to compete effectively unless our product selection keeps up with trends in the markets in which we compete or trends in new products. In addition, our ability to integrate new products and product lines into our distribution network could impact our ability to compete. Furthermore, the success of new products and new product lines will depend on market demand and there is a risk that new products and new product lines will not deliver expected results, which could negatively impact our future sales and results of operations.

We may not be able to successfully expand into new geographic markets.

Our expansion into new geographic markets may present competitive, distribution and regulatory challenges that differ from current ones. We may be less familiar with the target customers and may face different or additional risks, as well as increased or unexpected costs, compared to existing operations. Expansion into new geographic markets may also bring us into direct competition with companies with whom we have little or no past experience as competitors. To the extent we rely upon expansion into new geographic markets for growth and do not meet the new challenges posed by such expansion, our future sales growth could be negatively impacted, our operating costs could increase, and our business operations and financial results could be adversely affected.

We may not achieve the acquisition component of our growth strategy.

Acquisitions may continue to be an important component of our growth strategy; however, there can be no assurance that we will be able to continue to grow our business through acquisitions as we have done historically or that any businesses acquired will perform in accordance with expectations or that business judgments concerning the value, strengths and weaknesses of businesses acquired will prove to be correct. Future acquisitions may result in the incurrence of debt and contingent liabilities, an increase in interest expense and amortization expense and significant charges relative to integration costs. Our strategy could be impeded if we do not identify suitable acquisition candidates and our financial condition and results of operations will be adversely affected if we are unable to properly evaluate acquisition targets.

Acquisitions involve a number of special risks, including:

- 23 -

Table of Contents

In addition, we may not be able to obtain financing necessary to complete acquisitions on attractive terms or at all.

Increased fuel and energy prices, and our inability to obtain sufficient quantities of fuel to operate our in-house delivery fleet, could adversely affect our business, financial condition, results of operations and cash flows.

Energy and petroleum prices have fluctuated significantly in recent years. Prices and availability of petroleum products are subject to political, economic and market factors that are outside our control. Political events in petroleum-producing regions as well as hurricanes and other weather-related events may cause the price of fuel to increase.

We consume a large amount of energy and petroleum products in our operations, including the manufacturing process and delivering a significant volume of products to our customers by our in-house fleet. While we have implemented a diesel hedging program covering approximately 50% of our in-house fleet to mitigate against higher fuel prices, our operating profit will be adversely affected if we are unable to obtain the energy and fuel we require or to fully offset the anticipated impact of higher energy and fuel prices through increased prices or surcharges to our customers or through other hedging strategies. If shortages occur in the supply of energy or necessary petroleum products and we are not able to pass along the full impact of increased energy or petroleum prices to our customers, our business, financial condition, results of operations and cash flows would be adversely affected.

We have substantial fixed costs and, as a result, our income from operations is sensitive to changes in our net sales.

A significant portion of our expenses are fixed costs (including personnel). For fiscal years 2012, 2013 and 2014, domestic fixed costs were 26.3%, 27.2% and 26.4%, respectively, as a percentage of domestic net sales. Fixed costs do not fluctuate with net sales. Consequently, a percentage decline in our net sales could have a greater percentage effect on our income from operations if we do not act to reduce personnel or take other cost reduction actions. Any decline in our net sales would cause our profitability to be adversely affected. Moreover, a key element of our strategy is managing our assets, including our substantial fixed assets, more effectively, including through sales or other disposals of excess assets. Our failure to rationalize our fixed assets in the time, and within the costs, we expect could have a material adverse effect on our business, financial condition, results of operations and cash flows.

Our business is subject to risks associated with manufacturing processes.

We internally manufacture our own products at our facilities. While we maintain insurance covering our manufacturing and production facilities and have significant flexibility to manufacture and ship our own products from various facilities, a catastrophic loss of the use of certain of our facilities due to accident, fire, explosion, labor issues, weather conditions, other natural disaster or otherwise, whether short or long-term, could have a material adverse effect on our business, financial condition, results of operations and cash flows.

Unexpected failures of our equipment and machinery may result in production delays, revenue loss and significant repair costs, injuries to our employees, and customer claims. Any interruption in production capability may limit our ability to supply enough products to customers and may require us to make large capital

- 24 -

Table of Contents

expenditures to remedy the situation, which could have a negative impact on our profitability and cash flows. Our business interruption insurance may not be sufficient to offset the lost revenues or increased costs that we may experience during a disruption of our operations.

We provide product warranties that could expose us to claims, which could in turn damage our reputation and adversely affect our business, financial condition, results of operations and cash flows.

We generally provide limited product warranties on our products against defects in materials and workmanship in normal use and service. Most of our pipe products have a warranty that is not limited in duration. The warranty period for other products such as our StormTech chambers, our Inserta Tee product line, our BaySaver product line and our FleXstorm inlet protection systems is generally one year. Estimating the required warranty reserves requires a high level of judgment. Management estimates warranty reserves, based in part upon historical warranty costs, as a proportion of sales by product line. Management also considers various relevant factors, including its stated warranty policies and procedures, as part of its evaluation of its liability. Because warranty issues may surface later in the product life cycle, management continues to review these estimates on a regular basis and considers adjustments to these estimates based on actual experience compared to historical estimates. Although management believes that our warranty reserves at March 31, 2014 are adequate, actual results may vary from these estimates.

The nature of our business exposes us to construction defect and product liability claims as well as other legal proceedings.

We are exposed to construction defect and product liability claims relating to our various products if our products do not meet customer expectations. Such liabilities may arise out of the quality of raw materials we purchase from third-party suppliers, over which we do not have direct control. We also operate a large fleet of trucks and other vehicles and therefore face the risk of traffic accidents.

While we currently maintain insurance coverage to address a portion of these types of liabilities, we cannot make assurances that we will be able to obtain such insurance on acceptable terms in the future, if at all, or that any such insurance will provide adequate coverage against potential claims. Further, while we intend to seek indemnification against potential liability for products liability claims from relevant parties, we cannot guarantee that we will be able to recover under any such indemnification agreements. Product liability claims can be expensive to defend and can divert the attention of management and other personnel for significant time periods, regardless of the ultimate outcome. An unsuccessful product liability defense could be highly costly and accordingly result in a decline in revenues and profitability. In addition, even if we are successful in defending any claim relating to the products we distribute, claims of this nature could negatively impact customer confidence in us and our products.

From time to time, we are also involved in government inquiries and investigations, as well as consumer, employment, tort proceedings and other litigation. We cannot predict with certainty the outcomes of these legal proceedings and other contingencies, including potential environmental remediation and other proceedings commenced by government authorities. The outcome of some of these legal proceedings and other contingencies could require us to take actions which would adversely affect our operations or could require us to pay substantial amounts of money. Additionally, defending against these lawsuits and proceedings may involve significant expense and diversion of management’s attention and resources from other matters.

Because our business is working capital intensive, we rely on our ability to manage our supply purchasing and customer credit policies.

Our operations are working capital intensive, and our inventories, accounts receivable and accounts payable are significant components of our net asset base. We manage our inventories and accounts payable through our purchasing policies and our accounts receivable through our customer credit policies. If we fail to adequately manage our supply purchasing or customer credit policies, our working capital and financial condition may be adversely affected.

Table of Contents

Our operations are affected by various laws and regulations in the markets in which we operate, and our failure to obtain or maintain approvals by municipalities, state departments of transportation, engineers and developers may affect our results of operations.

Our operations are principally affected by various statutes, regulations and laws in the United States, Canada and Latin America. While we are not engaged in a regulated industry, we are subject to various laws applicable to businesses generally, including laws affecting land usage, zoning, the environment, health and safety, transportation, labor and employment practices (including pensions), competition, immigration and other matters. Additionally, approvals by municipalities, state departments of transportation, engineers and developers may affect the products our customers are allowed to use, and, consequently, failure to obtain or maintain such approvals may affect the saleability of our products. Building codes may also affect the products our customers are allowed to use, and, consequently, changes in building codes may also affect the saleability of our products. Changes in applicable regulations governing the sale of some of our products could increase our costs of doing business. In addition, changes to applicable tax laws and regulations could increase our costs of doing business. We cannot provide assurance that we will not incur material costs or liabilities in connection with regulatory requirements.

We deliver products to many of our customers through our own fleet of vehicles. The U.S. Department of Transportation, or DOT, regulates our operations in domestic interstate commerce. We are subject to safety requirements governing interstate operations prescribed by the DOT. Vehicle dimensions and driver hours of service also remain subject to both federal and state regulation. More restrictive limitations on vehicle weight and size, trailer length and configuration, or driver hours of service could increase our costs, which, if we are unable to pass these cost increases on to our customers, would reduce our gross margins and net income (loss) and increase our selling, general and administrative expenses.

We cannot predict whether future developments in law and regulations concerning our business units will affect our business, financial condition and results of operations in a negative manner. Similarly, we cannot assess whether our business units will be successful in meeting future demands of regulatory agencies in a manner which will not materially adversely affect our business, financial condition, results of operations and cash flows.

Interruptions in the proper functioning of IT systems could disrupt operations and cause unanticipated increases in costs or decreases in revenues, or both.

Because we use our information systems to, among other things, manage inventories and accounts receivable, make purchasing decisions and monitor our results of operations, the proper functioning of our IT systems is important to the successful operation of our business. Although our IT systems are protected through physical and software safeguards and remote processing capabilities exist, IT systems are still vulnerable to natural disasters, power losses, unauthorized access, telecommunication failures and other problems. If critical IT systems fail, or are otherwise unavailable, our ability to process orders, track credit risk, identify business opportunities, maintain proper levels of inventories, collect accounts receivable and pay expenses and otherwise manage our business units would be adversely affected.

Management uses information systems to support decision making and to monitor business performance. We may fail to generate accurate financial and operational reports essential for making decisions at various levels of management. Failure to adopt systematic procedures to maintain quality IT general controls could disrupt our business. In addition, if we do not maintain adequate controls such as reconciliations, segregation of duties and verification to prevent errors or incomplete information, our ability to operate our business could be limited.

Third-party service providers are responsible for managing a significant portion of our IT systems. Our business and results of operations may be adversely affected if the third-party service provider does not perform satisfactorily. Additionally, there is no guarantee that we will continue to have access to these third-party IT systems after our current license agreements expire, and, if we do not obtain licenses to use effective replacement IT systems, our financial condition and operating results could be adversely affected.

The implementation of our technology initiatives could disrupt our operations in the near term, and our technology initiatives might not provide the anticipated benefits or might fail.

We have made, and will continue to make, significant technology investments in each of our business units and in our administrative functions. Our technology initiatives are designed to streamline our operations to allow our associates to continue to provide high quality service to our customers and to provide our customers a better experience, while improving the quality of our internal control environment. The cost and potential problems and interruptions associated with the implementation of our technology initiatives could disrupt or reduce the efficiency of our operations in the near term. In addition, our new or upgraded technology might not provide the anticipated benefits, it might take longer than expected to realize the anticipated benefits or the technology might fail altogether.

We may experience a failure in or breach of our operational or information security systems, or those of our third-party service providers, as a result of cyber-attacks or information security breaches.

Information security risks have generally increased in recent years because of the proliferation of new technologies and the increased sophistication and activities of perpetrators of cyber-attacks. A failure in or breach of our operational or information security systems, or those of our third-party service providers, as a result of cyber-attacks or information security breaches could disrupt our business, result in the disclosure or misuse of confidential or proprietary information, damage our reputation, increase our costs and/or cause losses. As a result, cyber security and the continued development and enhancement of the controls and processes designed to protect our systems, computers, software, data and networks from attack, damage or unauthorized access remain a priority for us. As cyber threats continue to evolve, we may be required to expend additional significant resources to continue to enhance our information security measures and/or to investigate and remediate any information security vulnerabilities.

If we become subject to material liabilities under our self-insured programs, our financial results may be adversely affected.

We provide workers’ compensation, automobile and product/general liability coverage through a high deductible insurance program. In addition, we provide medical coverage to some of our employees through a self-insured preferred provider organization. Though we believe that we have adequate insurance coverage in excess of self-insured retention levels, our business, financial condition, results of operations and cash flows may be adversely affected if the number and severity of insurance claims increases.

We may see increased costs arising from health care reform.

In March 2010, the United States government enacted comprehensive health care reform legislation which, among other things, includes guaranteed coverage requirements, eliminates pre-existing condition exclusions and annual and lifetime maximum limits, restricts the extent to which policies can be rescinded and imposes new and significant taxes on health insurers and health care benefits. The legislation imposes implementation effective dates which began in 2010 and extend through 2020, and many of the changes require additional guidance from government agencies or federal regulations. Therefore, due to the phased-in nature of the implementation and the lack of interpretive guidance, it is difficult to determine at this time what impact the health care reform legislation will have on our financial results. Possible adverse effects of the health reform legislation include increased costs, exposure to expanded liability and requirements for us to revise ways in which we provide healthcare and other benefits to our employees. As a result, our business, financial condition, results of operations and cash flows could be materially adversely affected.

Our success depends upon our ability to control labor costs and to attract, train and retain highly-qualified employees and key personnel.

To be successful, we must attract, train and retain a large number of highly qualified employees while controlling related labor costs. Our ability to control labor costs is subject to numerous external factors, including prevailing wage rates and health and other insurance costs. We compete with other businesses for these

- 27 -

Table of Contents

employees and invest significant resources in training and motivating them. There is no assurance that we will be able to attract or retain highly-qualified employees in the future, including, in particular, those employed by companies we acquire. None of our domestic employees are currently covered by collective bargaining or other similar labor agreements. However, if a number of our employees were to unionize, including in the wake of any future legislation that makes it easier for employees to unionize, the effect on us may be negative. Any inability by us to negotiate acceptable new contracts under any collective bargaining arrangements could cause strikes or other work stoppages, and new contracts could result in increased operating costs. If any such strikes or other work stoppages occur, or if employees become represented by a union, we could experience a disruption of our operations and higher labor costs. Labor relations matters affecting our suppliers of products and services could also adversely affect our business from time to time.

In addition, our business results of operations depend largely upon our chief executive officer and senior management team as well as our plant managers and sales personnel, including those of companies recently acquired, and their experience, knowledge of local market dynamics and specifications and long-standing customer relationships. We customarily sign executive responsibility agreements with certain key personnel who are granted restricted stock or stock options under our employee incentive compensation programs, which contain confidentiality and non-competition provisions. However, in certain jurisdictions, non-competition provisions may not be enforceable or may not be enforceable to their full extent. Our inability to retain or hire qualified plant managers or sales personnel at economically reasonable compensation levels would restrict our ability to grow our business, limit our ability to continue to successfully operate our business and result in lower operating results and profitability.

If we are unable to protect our intellectual property rights, or we infringe on the intellectual property rights of others, our ability to compete could be negatively impacted.

Our ability to compete effectively depends, in part, upon our ability to protect and preserve proprietary aspects of our intellectual property, which we attempt to do, both in the United States and in foreign countries, through a combination of patent, trademark, copyright and trade secret laws, as well as licensing agreements and third-party nondisclosure and assignment agreements. Because of the differences in foreign trademark, patent and other laws concerning proprietary rights, our intellectual property rights may not receive the same degree of protection in foreign countries as they would in the United States. Our failure to obtain or maintain adequate protection of our intellectual property rights for any reason could have a material adverse effect on our business, results of operations and financial condition.

We have applied for patent protection relating to certain existing and proposed products, processes and services. While we generally apply for patents in those countries where we primarily intend to make, have made, use, or sell patented products, we may not accurately predict all of the countries where patent protection will ultimately be desirable. If we fail to timely file a patent application in any such country, we may be precluded from doing so at a later date. Furthermore, we cannot assure you that any of our patent applications will be approved. We also cannot assure you that the patents issuing as a result of our foreign patent applications will have the same scope of coverage as our United States patents. The patents we own could be challenged, invalidated or circumvented by others and may not be of sufficient scope or strength to provide us with any meaningful protection or commercial advantage. Further, we cannot assure you that competitors will not infringe our patents, or that we will have adequate resources to enforce our patents.

We also rely on unpatented proprietary technology. It is possible that others will independently develop the same or similar technology or otherwise obtain access to our unpatented technology. To protect our trade secrets and other proprietary information, we generally require applicable employees, consultants, advisors and collaborators to enter into confidentiality agreements. We cannot assure you that these agreements will provide meaningful protection for our trade secrets, know-how or other proprietary information in the event of any unauthorized use, misappropriation or disclosure of such trade secrets, know-how or other proprietary information. If we are unable to maintain the proprietary nature of our technologies, we could be materially adversely affected.

We rely on our trademarks, trade names and brand names to distinguish our products from the products of our competitors, and have registered or applied to register many of these trademarks. We cannot assure you that our trademark applications will be approved. Third parties may also oppose our trademark applications or otherwise challenge our use of the trademarks. In the event that our trademarks are successfully challenged, we could be forced to rebrand our products, which could result in loss of brand recognition, and could require us to devote resources to advertising and marketing new brands. Further, we cannot assure you that competitors will not infringe our trademarks or that we will have adequate resources to enforce our trademarks. We also license third parties to use certain of our trademarks. In an effort to preserve our trademark rights, we enter into license agreements with these third parties which govern the use of our trademarks and which require our licensees to abide by quality control standards with respect to the goods and services that they provide under our trademarks. Although we make efforts to police the use of our trademarks by our licensees, we cannot assure you that these efforts will be sufficient to ensure that our licensees abide by the terms of their licenses. In the event that our licensees fail to do so, our trademark rights could be diluted.

Although we rely on copyright laws to protect the works of authorship (including software) created by us, we generally do not register the copyrights in any of our copyrightable works. Copyrights of United States origin must be registered before the copyright owner may bring an infringement suit in the United States. Furthermore, if a copyright of United States origin is not registered within three months of publication of the underlying work, the copyright owner is precluded from seeking statutory damages or attorneys’ fees in any United States enforcement action, and is limited to seeking actual damages and lost profits. Accordingly, if one of our unregistered copyrights of United States origin is infringed by a third party, we will need to register the copyright before we can file an infringement suit in the United States, and our remedies in any such infringement suit may be limited.

The misuse of our intellectual property rights by others could adversely impact our ability to compete, cause our net sales to decrease or otherwise harm our business. If it became necessary for us to resort to litigation to protect our intellectual property rights, any proceedings could be burdensome and costly, and we may not prevail.

Also, we cannot be certain that the products that we sell do not and will not infringe issued patents or other intellectual property rights of others. Further, we are subject to legal proceedings and claims in the ordinary course of our business, including claims of alleged infringement of the patents, trademarks and other intellectual property rights of third parties by us or our customers, whom we generally indemnify in connection with their use of the products that we manufacture. These claims could divert management’s attention and resources and may require us to initiate or defend protracted and costly litigation on behalf of ourselves or our customers, regardless of the merits of the claims. Should we be found liable for infringement, we may be required to enter into licensing agreements (if available on acceptable terms or at all) or pay damages and cease making or selling certain products. Moreover, we may need to redesign or sell different products to avoid future infringement liability. Any of the foregoing could cause us to incur significant costs, prevent us from selling our products or negatively impact our ability to compete.

Income tax payments may ultimately differ from amounts currently recorded by us. Future tax law changes may materially increase our prospective income tax expense.

We are subject to income taxation in many jurisdictions in the United States as well as foreign jurisdictions. Judgment is required in determining our worldwide income tax provision and, accordingly, there are many transactions and computations for which our final income tax determination is uncertain. We are routinely audited by income tax authorities in many tax jurisdictions. Although we believe the recorded tax estimates are reasonable, the ultimate outcome from any audit (or related litigation) could be materially different from amounts reflected in our income tax provisions and accruals. Future settlements of income tax audits may have a material effect on earnings between the period of initial recognition of tax estimates in the financial statements and the point of ultimate tax audit settlement. Additionally, it is possible that future income tax legislation in any jurisdiction to which we are subject may be enacted that could have a material impact on our worldwide income tax provision beginning with the period that such legislation becomes effective.

We could incur significant costs in complying with environmental, health and safety laws or permits or as a result of satisfying any liability or obligation imposed under such laws or permits.

Our operations are subject to various federal, state, local and foreign environmental, health and safety laws and regulations. Among other things, these laws regulate the emission or discharge of materials into the environment, govern the use, storage, treatment, disposal and management of hazardous substances and wastes, protect the health and safety of our employees and the end users of our products, regulate the materials used in and the recycling of products and impose liability for the costs of investigating and remediating, and damages resulting from, present and past releases of hazardous substances. Violations of these laws and regulations, failure to obtain or maintain required environmental permits or non-compliance with any conditions contained in any environmental permit can result in substantial fines or penalties, injunctive relief, requirements to install pollution or other controls or equipment, civil and criminal sanctions, permit revocations and/or facility shutdowns. We could be held liable for the costs to address contamination of any real property we have ever owned, leased, operated or used, including as a disposal site. We could also incur fines, penalties, sanctions or be subject to third-party claims for property damage, personal injury or nuisance or otherwise as a result of violations of or liabilities under environmental laws in connection with releases of hazardous or other materials.

In addition, changes in, or new interpretations of, existing laws, regulations or enforcement policies, the discovery of previously unknown contamination, or the imposition of other environmental liabilities or obligations in the future, including additional investigation or other obligations with respect to any potential health hazards of our products or business activities or the imposition of new permit requirements, may lead to additional compliance or other costs that could have material adverse effect on our business, financial condition, results of operations and cash flows.

Our failure to maintain effective disclosure controls and internal control over financial reporting could adversely affect our business, financial position and results of operations.

Upon completion of this offering, we will be required to evaluate the effectiveness of our disclosure controls and internal control over financial reporting on a periodic basis and publicly disclose the results of these evaluations and related matters, in accordance with the requirements of Section 404 of the Sarbanes-Oxley Act of 2002. These reporting and other obligations place significant additional demands on our management and administrative and operational resources, including our accounting resources, which could adversely affect our operations among other things. To comply with these requirements, we have upgraded, and are continuing to upgrade our systems, including information technology, implemented additional financial and management controls, reporting systems and procedures. We cannot be certain that we will be successful in maintaining adequate control over our financial reporting and financial processes. Furthermore, as we grow our business, our disclosure controls and internal controls will become more complex, and we may require significantly more resources to ensure that these controls remain effective. If we are unable to continue upgrading our financial and management controls, reporting systems, information technology and procedures in a timely and effective fashion, additional management and other resources may need to be devoted to assist in compliance with the disclosure and financial reporting requirements and other rules that apply to reporting companies, which could adversely affect our business, financial position and results of operations.

We have not been required to have and have not had our independent registered public accounting firm perform an evaluation of our internal control over financial reporting as of the end of our last fiscal year in accordance with the provisions of the Sarbanes-Oxley Act of 2002. Had our independent registered public accounting firm performed an evaluation of our internal control over financial reporting in accordance with the provisions of the Sarbanes-Oxley Act of 2002, additional control deficiencies may have been identified by our independent registered public accounting firm and those control deficiencies could have also represented one or more material weaknesses.

Future changes in financial accounting standards may significantly change our reported results of operations.

In an exposure draft issued in August 2010 and revised in May 2013, the Financial Accounting Standards Board, or FASB, together with the International Accounting Standards Board, proposed a comprehensive set of changes in accounting for leases. The lease accounting model contemplated by these changes is a “right of use” model that assumes that each lease creates an asset (the lessee’s right to use the leased asset) and a liability (the future rent payment obligations) which should be reflected on a lessee’s balance sheet to fairly represent the lease transaction and the lessee’s related financial obligations. We conduct some of our operations under leases that are accounted for as operating leases, with no related assets and liabilities on our balance sheet. The proposed changes would require that substantially all of our operating leases be recognized as assets and liabilities on our balance sheet. The effective date has not been determined. Comments on the revised exposure draft were due by September 13, 2013. Changes in lease accounting rules or their interpretation, or changes in underlying assumptions, estimates or judgments by us could significantly change our reported or expected financial performance.

A change in our product mix could adversely affect our results of operations.

Our results may be affected by a change in our product mix on which our gross margin depends. Our Allied Products typically provide higher gross margin than our pipe products. Changes in our product mix may result from marketing activities to existing customers and needs communicated to us from existing and prospective customers. Our outlook, budgeting and strategic planning assume a certain product mix of sales. If actual results vary from this projected product mix of sales, our financial results could be negatively impacted.

We may be affected by global climate change or by legal, regulatory or market responses to such potential change.

Concern over climate change, including the impact of global warming, has led to significant federal, state, and international legislative and regulatory efforts to limit greenhouse gas, or GHG, emissions. For example, in the past several years, the U.S. Congress has considered various bills that would regulate GHG emissions. While these bills have not yet received sufficient Congressional support for enactment, some form of federal climate change legislation is possible in the future. Even in the absence of such legislation, the EPA, spurred by judicial interpretation of the Clean Air Act, has begun regulating GHG emissions following its issuance of the “Tailoring Rule” that determines which stationary sources require permits for greenhouse emissions. EPA has issued rules that require monitoring and reporting of annual GHG emissions, as well as performance standards for CO2 emissions from new fossil-fuel electric utility generating units. Thus far, EPA has addressed vehicle and mobile source emissions by implementing Renewable Fuel Standard regulations and by working with manufacturers to improve fuel efficiency in new vehicles. However, EPA has been directed by President Obama to develop and issue new fuel efficiency standards for medium- and heavy-duty vehicles by March 2016, especially diesel engine emissions, and this could impose substantial costs on us. These costs include an increase in the cost of the fuel and other energy we purchase and capital costs associated with updating or replacing our internal fleet of trucks and other vehicles in order to comply with application regulations. In addition, new laws or future regulation could directly and indirectly affect our customers and suppliers (through an increase in the cost of production or their ability to produce satisfactory products) and our business (through the impact on our inventory availability, cost of sales, operations or demands for the products we sell). Until the timing, scope and extent of any future regulation becomes known, we cannot predict its effect on our cost structure or our operating results. Notwithstanding our dedication to being a responsible corporate citizen, it is reasonably possible that such legislation or regulation could impose material costs on us.

Anti-terrorism measures and other disruptions to the raw material supply network could impact our operations.

Our ability to provide efficient distribution of products to our customers is an integral component of our overall business strategy. In the aftermath of terrorist attacks in the United States, federal, state and local

authorities have implemented and continue to implement various security measures that affect the raw material supply network in the United States and abroad. If security measures disrupt or impede the receipt of sufficient raw materials, we may fail to meet the needs of our customers or may incur increased expenses to do so.

Risks Relating to Our Indebtedness

We have substantial debt and may incur substantial additional debt, which could adversely affect our financial health, reduce our profitability, limit our ability to obtain financing in the future and pursue certain business opportunities and reduce the value of your investment.

As of March 31, 2014, we had an aggregate principal amount of $454.0 million of outstanding debt. In the fiscal year ended March 31, 2014, we incurred $16.1 million of interest expense.

The amount of our debt or such other obligations could have important consequences for holders of our common stock, including, but not limited to:

If our cash flow and capital resources are insufficient to fund our debt service obligations, we may be forced to reduce or delay capital expenditures, sell assets, seek to obtain additional equity capital or refinance our debt. We cannot make assurances that we will be able to refinance our debt on terms acceptable to us, or at all. In the future, our cash flow and capital resources may not be sufficient for payments of interest on and principal of our debt, and such alternative measures may not be successful and may not permit us to meet our scheduled debt service obligations.

We cannot make assurances that we will be able to refinance any of our indebtedness, or obtain additional financing, particularly because of our high levels of debt and the debt incurrence restrictions imposed by the agreements governing our debt, as well as prevailing market conditions. We could face substantial liquidity problems and might be required to dispose of material assets or operations to meet our debt service and other obligations. Subject to certain exceptions, our Senior Loan Facilities and our Senior Notes, which we have defined in “Description of Certain Indebtedness,” restrict our ability to dispose of assets and how we use the

- 32 -

Table of Contents

proceeds from any such dispositions. We cannot make assurances that we will be able to consummate those dispositions, or if we do, what the timing of the dispositions will be or whether the proceeds that we realize will be adequate to meet our debt service obligations, when due.

Despite our current level of indebtedness, we may still be able to incur substantially more debt. This could further exacerbate the risks to our financial condition described above.

We may be able to incur significant additional indebtedness in the future. Although the agreements governing our indebtedness contain restrictions on the incurrence of additional indebtedness, these restrictions are subject to a number of qualifications and exceptions, and the additional indebtedness incurred in compliance with these restrictions could be substantial. These restrictions also will not prevent us from incurring obligations that do not constitute indebtedness, including obligations under lease arrangements that are currently recorded as operating leases even if operating leases were to be treated as debt under GAAP. In addition, our Revolving Credit Facility provides an aggregate commitment of up to $325.0 million. As of March 31, 2014, we had an additional $68.4 million of availability under the Revolving Credit Facility plus $12.0 million in indebtedness outstanding under a separate revolving credit facility with our subsidiary, ADS Mexicana, S.A. de C.V. If new debt is added to our current debt levels, the related risks that we now face could intensify. See “Description of Certain Indebtedness.”

The agreements and instruments governing our debt contain restrictions and limitations that could significantly impact our ability to operate our business and adversely affect the holders of our common stock.

The covenants contained in our Senior Loan Facilities and our Senior Notes, which we refer to collectively as our Credit Facilities, are consistent. These covenants, among other things, restrict or limit our ability to:

Our ability to comply with the covenants and restrictions contained in the Credit Facilities may be affected by economic, financial and industry conditions beyond our control. The breach of any of these covenants or restrictions could result in a default under the Credit Facilities that would permit the applicable lenders or noteholders, as the case may be, to declare all amounts outstanding thereunder to be due and payable, together with accrued and unpaid interest. If we are unable to repay indebtedness, secured parties having secured obligations, such as the lenders under the Credit Facilities, could proceed against the collateral securing the secured obligations. This could have serious consequences to our financial condition and results of operations and could cause us to become bankrupt or insolvent.

We may have future capital needs and may not be able to obtain additional financing on acceptable terms.

Although we believe that our current cash position and the additional committed funding available under our Credit Facilities is sufficient for our current operations, any reductions in our available borrowing capacity, or

- 33 -

Table of Contents

our inability to renew or replace our debt facilities, when required or when business conditions warrant, could have a material adverse effect on our business, financial condition and results of operations. The economic conditions, credit market conditions, and economic climate affecting our industry, as well as other factors, may constrain our financing abilities. Our ability to secure additional financing, if available, and to satisfy our financial obligations under indebtedness outstanding from time to time will depend upon our future operating performance, the availability of credit generally, economic conditions and financial, business and other factors, many of which are beyond our control. The market conditions and the macroeconomic conditions that affect our industry could have a material adverse effect on our ability to secure financing on favorable terms, if at all.

If financing is not available when needed, or is available on unfavorable terms, we may be unable to take advantage of business opportunities or respond to competitive pressures, any of which could have a material adverse effect on our business, financial condition and results of operations. If we raise additional funds through further issuances of equity, convertible debt securities or other securities convertible into equity, our existing stockholders could suffer significant dilution in their percentage ownership, and any new securities we issue could have rights, preferences and privileges senior to those of holders of our common stock.

Increases in interest rates would increase the cost of servicing our debt and could reduce our profitability.

A significant portion of our outstanding debt, including the debt under our Senior Loan Facilities, bears interest at variable rates. As a result, increases in interest rates would increase the cost of servicing our debt and could materially reduce our profitability and cash flows. Each 1.0% increase in interest rates on our variable-rate debt would increase our annual forecasted interest expense by approximately $2.3 million based on balances as of March 31, 2014. Assuming all revolving loans were fully drawn, each 1.0% increase in interest rates would result in a $2.8 million increase in annual cash interest expense on our Credit Facilities.

With respect to the indebtedness outstanding under our Credit Facilities that bear interest at variable rates, such variable rates are determined based upon specified pricing terms. As a result, if our leverage ratios increase, then such variable rates could also increase. See “Description of Certain Indebtedness.”

We may not be able to satisfy our outstanding obligations upon a change of control.

Under the Senior Loan Facility, a change of control (as defined therein) constitutes an event of default that permits the lenders to accelerate the maturity of borrowings under the agreement and terminate their commitments to lend. Additionally, under the Senior Notes, a change of control (as defined therein) constitutes an event of default that permits the noteholders to declare all of their notes to be immediately due and payable. In order to avoid events of default under each of our Credit Facilities, we may therefore have to avoid certain change of control transactions that would otherwise be beneficial to us.

Risks Relating to Our Common Stock and This Offering

Our ability to make future dividend payments, if any, may be restricted.

We have a history of paying dividends to our stockholders when sufficient cash is available, and we currently intend to pay dividends in the future after this offering. Any determination to pay dividends on our capital stock in the future will be at the discretion of our board of directors, subject to applicable laws and the provisions of our amended and restated certificate of incorporation (including those relating to the payment of dividends on our convertible preferred stock), and will depend on our financial condition, results of operations, capital requirements, general business conditions and other factors that our board of directors considers relevant. For more information on our convertible preferred stock, see “Description of Capital Stock — Preferred Stock.” In addition, the terms of our Credit Facilities contain restrictions on our ability to pay dividends. Also, Delaware law may impose requirements that may restrict our ability to pay dividends to holders of our common stock. See “Dividend Policy.”

Our common stock has no prior public market and the market price of our common stock may be volatile and could decline after this offering.

Prior to this offering, there has not been a public market for our common stock, and an active market for our common stock may not develop or be sustained after this offering. We will negotiate the initial public offering price per share with the representatives of the underwriters and therefore, that price may not be indicative of the market price of our common stock after this offering. We cannot assure you that an active public market for our common stock will develop after this offering or, if it does develop, will be sustained. In the absence of a public trading market, you may not be able to liquidate your investment in our common stock. In addition, the market price of our common stock may fluctuate significantly. Among the factors that could affect our stock price are:

In particular, we cannot assure you that you will be able to resell your shares at or above the initial public offering price. The stock markets have experienced extreme volatility in recent years that has been unrelated to the operating performance of particular companies. These broad market fluctuations may adversely affect the trading price of our common stock. In the past, following periods of volatility in the market price of a company’s securities, class action litigation has often been instituted against such company. Any litigation of this type brought against us could result in substantial costs and a diversion of our management’s attention and resources, which would harm our business, operating results and financial condition.

Future sales of shares by existing stockholders, including our ESOP, could cause our stock price to decline.

Sales of substantial amounts of our common stock in the public market following this offering, or the perception that these sales could occur, could cause the market price of our common stock to decline. Based on shares outstanding as of March 31, 2014, upon completion of this offering, we will have             outstanding shares of common stock (or             outstanding shares of common stock, assuming exercise in full by the underwriters of

their option to purchase additional shares). All of the shares sold pursuant to this offering will be immediately tradeable without restriction under the Securities Act of 1933, as amended, unless held by “affiliates,” as that term is defined in Rule 144 under the Securities Act. The remaining shares of common stock outstanding upon completion of this offering will be restricted securities within the meaning of Rule 144 under the Securities Act. Restricted securities may be sold in the public market only if their offer and sale is registered under the Securities Act or if the offer and sale of those securities qualify for an exemption from registration, including exemptions provided by Rules 144 and 701 under the Securities Act, subject to the terms of the lock-up agreements entered into among us, Barclays Capital Inc. and Deutsche Bank Securities Inc., as the representatives of the underwriters, and stockholders holding more than     % of our common stock prior to this offering. Upon completion of this offering, we intend to file one or more registration statements under the Securities Act to register the shares of common stock to be issued under our equity compensation plans and, as a result, all shares of common stock acquired upon exercise of stock options granted under our plans will also be freely tradable under the Securities Act, subject to the terms of the lock-up agreements, unless purchased by our affiliates. As of March 31, 2014, there were stock options outstanding to purchase a total of             approximately             shares of our common stock. In addition,             shares of common stock are reserved for future issuance under our 2013 Stock Option Plan.

We, stockholders holding more than     % of our common stock prior to this offering and our executive officers and directors have agreed to a “lock-up,” meaning that, subject to certain exceptions, neither we nor they will sell any shares of our common stock without the prior consent of Barclays Capital Inc. and Deutsche Bank Securities Inc., as the representatives of the underwriters, for 180 days after the date of this prospectus. Following the expiration of this 180-day lock-up period, approximately         million shares of our common stock will be eligible for future sale, subject to the applicable volume, manner of sale, holding period and other limitations of Rule 144. See “Shares of Common Stock Eligible for Future Sale” for a discussion of the shares of common stock that may be sold into the public market in the future. In addition, certain of our significant stockholders may distribute shares that they hold to their investors who themselves may then sell into the public market following the expiration of the lock-up period. Such sales may not be subject to the volume, manner of sale, holding period and other limitations of Rule 144. As resale restrictions end, the market price of our common stock could decline if the holders of those shares sell them or are perceived by the market as intending to sell them. Barclays Capital Inc. and Deutsche Bank Securities Inc., as the representatives of the underwriters, may, in their sole discretion and at any time, release all or any portion of the securities subject to lock-up agreements entered into in connection with this offering. See “Underwriting.”

All of the shares of our convertible preferred stock held by our ESOP may be converted into our common stock at any time by action of the ESOP trustee, and will be automatically converted into our common stock upon distributions of such shares allocated to the ESOP accounts of ESOP participants upon a distribution event such as retirement and other termination of employment. Such distributed common stock will not be subject to any lock-up agreement and will be eligible for future sale, subject to the applicable volume, manner of sale, holding period and other limitations of Rule 144. As of March 31, 2014, there were approximately 5.6 million shares of convertible preferred stock held by our ESOP, which in aggregate could be converted into approximately 4.3 million shares of our common stock. All of these shares will be eligible for future sale, either by the ESOP trustee or by ESOP participants, subject to the limitations of Rule 144. After the completion of this offering, the convertible preferred stock held by our ESOP will account for approximately     % of our common stock on a fully-converted basis, assuming no exercise of the underwriters’ option to purchase additional shares, or     %, assuming exercise in full of the underwriters’ option to purchase additional shares. See “Description of Employee Stock Ownership Plan” for shares relating to distributions and diversifications during fiscal years 2012, 2013 and 2014.

In the future, we may issue additional shares of common stock or other equity or debt securities convertible into common stock in connection with a financing, acquisition, litigation settlement or employee arrangement or otherwise. Any of these issuances could result in substantial dilution to our existing stockholders and could cause the trading price of our common stock to decline.

If securities or industry analysts do not publish research or publish misleading or unfavorable research about our business, our stock price and trading volume could decline.

The trading market for our common stock will depend in part on the research and reports that securities or industry analysts publish about us or our business. We do not currently have and may never obtain research coverage by securities and industry analysts. If there is no coverage of us by securities or industry analysts, the trading price for our stock would be negatively impacted. In the event we obtain securities or industry analyst coverage, if one or more of these analysts downgrades our stock or publishes misleading or unfavorable research about our business, our stock price would likely decline. If one or more of these analysts ceases coverage of us or fails to publish reports on us regularly, demand for our stock could decrease, which could cause our stock price or trading volume to decline.

Our directors, officers and principal stockholders have significant voting power and may take actions that may not be in the best interests of our other stockholders.

Prior to completion of this offering, our directors, officers and principal stockholders and their affiliates collectively own approximately 91% of our outstanding shares of common stock. Additionally, our ESOP holds convertible preferred stock that converts into a substantial number of shares of our common stock and, prior to conversion, is entitled to vote on a one-for-one basis on any matter requiring the vote or consent of our stockholders, voting together with our common stock as a single class unless otherwise required by law. Thus, the collective voting power of our directors, officers and principal stockholders and their affiliates prior to completion of this offering is approximately 94%, inclusive of the outstanding shares of convertible preferred stock held by the ESOP. After this offering, assuming no exercise of the underwriters’ option to purchase additional shares, our directors, officers and principal stockholders and their affiliates collectively will hold approximately         % of our voting power, inclusive of the outstanding shares of convertible preferred stock held by the ESOP. As a result, these stockholders, if they act together, may be able to control our management and affairs and most matters requiring stockholder approval, including the election of directors and approval of significant corporate transactions. This concentration of ownership may have the effect of delaying or preventing a change of control and might adversely affect the market price of our common stock. This concentration of ownership may not be in the best interests of our other stockholders.

The trustee of our ESOP has certain limited powers to vote a large block of shares on matters presented to stockholders for approval.

In general, the trustee of the ESOP votes the shares of stock held by the ESOP as directed by the ESOP’s committee. Consequently, the trustee of the ESOP, per the ESOP committee’s discretion, has the ability to vote a significant block of shares on certain matters presented to shareholders for approval. However, in the event of either a corporate matter with respect to the approval or disapproval of any corporate merger or consolidation, recapitalization, reclassification, liquidation, dissolution, sale of substantially all of the assets of a trade or business or with respect to any tender or exchange offer, or a request or invitation for tenders or exchanges, each participant in the ESOP may direct the trustee of the ESOP on how to vote the shares of stock allocated to the participant’s ESOP accounts; and the trustee must vote any unallocated stock and allocated stock for which no participant instructions were received in the same proportion as the allocated stock for which participants’ voting instructions have been received is voted.

Fulfilling our obligations incident to being a public company, including with respect to the requirements of and related rules under the Sarbanes-Oxley Act of 2002, will be expensive and time-consuming, and any delays or difficulties in satisfying these obligations could have a material adverse effect on our future results of operations and our stock price.

Following this offering, we will be subject to the reporting and corporate governance requirements, the listing standards of the New York Stock Exchange, or the NYSE, and the Sarbanes-Oxley Act of 2002, that apply to issuers of listed equity, which will impose certain new compliance costs and obligations upon us. The changes

necessitated by publicly listing our equity will require a significant commitment of additional resources and management oversight which will increase our operating costs. These changes will also place additional demands on our finance and accounting staff and on our financial accounting and information systems. Other expenses associated with being a public company include increases in auditing, accounting and legal fees and expenses, investor relations expenses, increased directors’ fees and director and officer liability insurance costs, registrar and transfer agent fees and listing fees, as well as other expenses. As a public company, we will be required, among other things, to:

In particular, beginning with the year ending March 31, 2016, our independent registered public accounting firm will be required to provide an attestation report on the effectiveness of our internal control over financial reporting pursuant to Section 404(b) of the Sarbanes-Oxley Act of 2002. If our independent registered public accounting firm is unable to provide us with an unqualified report regarding the effectiveness of our internal control over financial reporting (at such time as it is required to do so), investors could lose confidence in the reliability of our financial statements. This could result in a decrease in the value of our common stock. Failure to comply with the Sarbanes-Oxley Act of 2002 could potentially subject us to sanctions or investigations by the SEC, NYSE, or other regulatory authorities.

Anti-takeover provisions in our charter documents and Delaware law could discourage, delay or prevent a change in control of us and may affect the trading price of our common stock.

Our amended and restated certificate of incorporation and amended and restated bylaws will include a number of provisions that may discourage, delay or prevent a change in our management or control over us that stockholders may consider favorable. For example, our amended and restated certificate of incorporation and amended and restated bylaws will:

- 38 -

Table of Contents

Any provision of our amended and restated certificate of incorporation, amended and restated bylaws or DGCL that has the effect of delaying or deterring a change in control could limit the opportunity for our stockholders to receive a premium for their shares of our common stock, and could also affect the price that some investors are willing to pay for our common stock. See “Description of Capital Stock — Anti-Takeover Effects of our Certificate of Incorporation and Bylaws.”

Our amended and restated certificate of incorporation and amended and restated bylaws may also make it difficult for stockholders to replace or remove our management. These provisions may facilitate management entrenchment that may delay, deter, render more difficult or prevent a change in our control, which may not be in the best interests of our stockholders.

Our amended and restated certificate of incorporation will provide that the Court of Chancery of the State of Delaware will be the exclusive forum for substantially all disputes between us and our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers, employees or agents.

Our amended and restated certificate of incorporation will provide that the Court of Chancery of the State of Delaware will be the exclusive forum for any derivative action or proceeding brought on our behalf; any action asserting a claim of breach of a fiduciary duty owed to us or our stockholders by our directors, officers, employees or agents; any action asserting a claim against us arising under the Delaware General Corporation Law, our amended and restated certificate of incorporation or our amended and restated bylaws; or any action asserting a claim against us that is governed by the internal affairs doctrine. Any person or entity purchasing or otherwise acquiring any interest in shares of our common stock shall be deemed to have notice of and to have consented to the provisions of our amended and restated certificate of incorporation described above. The choice of forum provision may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our directors, officers, employees or agents, which may discourage such lawsuits against us or our directors, officers, employees or agents. If a court were to find the choice of forum provision contained in our amended and restated certificate of incorporation to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving such action in other jurisdictions, which could adversely affect our business and financial condition.

Investors purchasing common stock in this offering will experience immediate and substantial dilution as a result of this offering and future equity issuances.

If you purchase shares of our common stock in this offering, you will incur immediate and substantial dilution in the book value of your stock, because the price that you pay will be substantially greater than the net tangible book value per share of the shares you acquire. As a result, you will pay a price per share that substantially exceeds the book value of our assets after subtracting our liabilities. The net tangible book value per share, calculated as of March 31, 2014 and after giving effect to the offering (assuming an initial public offering price of $         per share, the midpoint of the price range set forth on the cover page of this prospectus), is $        . Investors purchasing common stock in this offering will experience immediate and substantial dilution of $         a share, based on an initial public offering price of $        , which is the midpoint of the price range set forth on the cover page of this prospectus. In addition, we have issued options to acquire common stock at prices significantly below the initial public offering price. To the extent outstanding options are ultimately exercised, there will be further dilution to investors in this offering. In addition, if the underwriters exercise in full their option to purchase additional shares, or if we issue additional equity securities in the future, investors purchasing common stock in this offering will experience additional dilution. See “Dilution.”
