BASIS OF PRESENTATION

        On April 1, 2014, GMS Inc., or the Successor, acquired, through its wholly-owned entities, GYP Holdings II Corp. and GYP Holdings III Corp., all of the capital stock of Gypsum Management and Supply, Inc., or the Predecessor. We refer to this acquisition as the "Acquisition."

        As a result of the Acquisition and resulting change in control and changes due to the impact of purchase accounting, we are required to present separately the operating results for the Predecessor periods ending on or prior to March 31, 2014 and the Successor periods beginning on or after April 1, 2014. Accordingly, unless otherwise indicated or the context otherwise requires, all references in this Annual Report on Form 10-K to "the Company," "GMS," "we," "us," "our" and other similar terms mean (1) the Predecessor for periods ending on or prior to March 31, 2014 and (2) the Successor for periods beginning on or after April 1, 2014, in each case together with its consolidated subsidiaries.

        Our fiscal year ends on April 30 of each year. References in this Annual Report on Form 10-K to a fiscal year mean the year in which that fiscal year ends. References in this Annual Report on Form 10-K to "fiscal 2012" relate to the fiscal year ended April 30, 2012, references in this Annual Report on Form 10-K to "fiscal 2013" relate to the fiscal year ended April 30, 2013, references in this Annual Report on Form 10-K to "fiscal 2015" relate to the fiscal year ended April 30, 2015 and references in this Annual Report on Form 10-K to "fiscal 2016" relate to the fiscal year ended April 30, 2016. References in this Annual Report on Form 10-K to "full year 2014" represent the sum of the results of the eleven month period from May 1, 2013 to March 31, 2014 and the one month period from April 1, 2014 to April 30, 2014.

        The audited financial statements included in this Annual Report on Form 10-K include a black line division to indicate that the Predecessor and Successor reporting entities have applied different bases of accounting and are not comparable. Please note that our discussion of certain financial information for the full year ended April 30, 2014, specifically net sales and Adjusted EBITDA, includes data from the Predecessor and Successor periods on a combined basis for the full year 2014. The change in basis resulting from the Acquisition did not impact such financial information and, although this presentation of financial information on a combined basis does not comply with generally accepted accounting principles in the United States, or GAAP, we believe it provides a meaningful method of comparison to the other periods presented in this Annual Report on Form 10-K. The data is being presented for analytical purposes only. Combined operating results (1) have not been prepared on a pro forma basis as if the Acquisition occurred on the first day of the period, (2) may not reflect the actual results we would have achieved absent the Acquisition and (3) may not be predictive of future results of operations.

PART I

Item 1.    Business

History and Company Overview

        Founded in 1971, we are the leading North American distributor of wallboard and suspended ceilings systems, or ceilings. Our core customer is the interior contractor, who typically installs wallboard, ceilings and our other interior construction products in commercial and residential buildings. As a leading specialty distributor, we serve as a critical link between our suppliers and a highly fragmented customer base of over 20,000 contractors. Our operating model combines a national platform with a local go-to-market strategy through over 185 branches across the country. We believe this combination enables us to generate economies of scale while maintaining the high service levels, entrepreneurial culture and customer intimacy of a local business.

        On April 1, 2014, GMS Inc., or the Successor, acquired, through its wholly-owned entities, GYP Holdings II Corp. and GYP Holdings III Corp., all of the capital stock of Gypsum Management and Supply, Inc., or the Predecessor. We refer to this acquisition as the "Acquisition." Successor is a controlled company, within the meaning of the corporate governance standards of the New York Stock Exchange, by certain affiliates of AEA Investors LP, which we refer to as "AEA" or our "Sponsor," and certain of our other stockholders through a majority of the voting power of our outstanding common stock.

Initial Public Offering

        On June 1, 2016, we completed our initial public offering, or IPO, of 8,050,000 shares of common stock at a price of $21.00 per share, including 1,050,000 shares of common stock that were issued as a result of the exercise in full by the underwriters of an option to purchase additional shares to cover over-allotments. Our common stock began trading on the New York Stock Exchange, or the NYSE, on May 26, 2016 under the ticker symbol "GMS". After underwriting discounts and commissions but before expenses, we received net proceeds from the IPO of approximately $157.2 million. We used these proceeds together with cash on hand to repay $160.0 million principal amount, of our term loan debt outstanding under our senior secured second lien term loan facility, or the Second Lien Facility, which was a payment in full of the entire loan balance due under the Second Lien Facility.

Products

        We provide a comprehensive product offering of over 20,000 stock-keeping-units, or SKUs, of wallboard, ceilings and complementary interior construction products for interior contractors. By carrying a full line of wallboard and ceilings along with steel framing and ancillary products, we are able to serve as a one-stop-shop for our customers.

Table of Contents

Wallboard

        Wallboard is one of the most widely used building products for interior and exterior walls and ceilings in residential and commercial structures due to its low cost, ease of installation and superior performance in providing comfort, fire resistance, thermal insulation, sound insulation, mold and moisture resistance, impact resistance, aesthetics and design elements. Wallboard is sold in panels of various dimensions, suited to various applications. In commercial and institutional construction projects, architectural specifications and building codes provide requirements related to the thickness of the panels and, in some cases, other characteristics, including fire resistance. In addition, there are wallboard products that provide some additional value in use. These include lighter weight panels, panels with additional sound insulation, and panels coated to provide mold and moisture resistance. In addition to the interior wallboard products described above, exterior sheathing is a water-resistant wallboard product designed for attachment to exterior side-wall framing as an underlayment for various exterior siding materials. These panels are manufactured with a treated, water-resistant core faced with water-repellent paper on both face and back surfaces and long edges.

        While highly visible and essential, wallboard typically comprises only 3% to 5% of a new home's total cost. Given its low price point relative to other materials, we believe that there is no economical substitute for wallboard in either residential or commercial applications. We believe wallboard demand is driven by a balanced mix of both residential and commercial new construction as well as R&R activity.

Ceilings

        Our ceilings product line consists of suspended mineral fiber, soft fiber and metal ceiling systems primarily used in offices, hotels, hospitals, retail facilities, schools and a variety of other commercial and institutional buildings. The principal components of our ceiling systems are typically square mineral fiber tiles and the metal grid that holds the tile in place. The systems vary by acoustical performance characteristics, reflectivity, color, fire protection and aesthetic appeal. In addition to these systems, we have expanded our ceilings product offering to include architectural specialty ceilings. This product line consists of a variety of specialty shapes that provide a room with a unique visual effect as well as enhanced acoustical performance. As a result of the specified, often customized nature of these products, architectural specialty ceilings are a growing, high margin component of our product offering.

        Our ceilings product line is almost exclusively sold into commercial and institutional applications. Because interior contractors who purchase ceilings frequently buy wallboard from the same distributor, carrying our ceilings product line helps increase our sales of wallboard and other complementary products, which are often delivered together with ceilings to the same worksite as part of a commercial package.

        In the ceilings market, brand is highly valued and often specified by the architect of a commercial building. Because of our strong market position, we have exclusive access to the leading ceilings brand in many of our local markets. Where we have exclusivity, these specifications help us drive sales of ceilings products as well as all of the complementary products we sell as part of our commercial package. In effect, our exclusivity on the leading ceiling tile brand creates a virtuous cycle which helps reinforce our market position in our other products. In addition, because ceiling tile systems differ in size, shape and aesthetic appeal between manufacturers, they are often replaced with the same brand for R&R projects. As a result, the leading brand's installed base of product generates built in demand for replacement product over time. Because we have exclusive access to that brand in certain markets, we benefit from these recurring sales.

Steel Framing

        Our steel framing product line consists of steel track, studs and the various other steel products used to frame the interior walls of a commercial or institutional building. Typically the contractor who installs the steel framing also installs the wallboard, and the two products along with ceilings, insulation and other products are sold together as part of a commercial package. Nearly all of our steel framing products are sold for use in commercial buildings.

Other Products

        In addition to our three main product lines, we supply our customers with complementary products, including insulation, ready-mix-joint compound and various other interior construction products. We also supply our customers with the ancillary products they need to complete the job including tools and safety products. We partner with leading branded vendors for many of these products and allow them to merchandise their products in our show rooms that are adjacent to many of our warehouses.

Our Industry

        As the U.S. construction market evolved during the second half of the 20^th century, contractors began to specialize in specific trades within the construction process, and specialty distributors emerged to supply them. One of these trades was wallboard and ceilings installation, and we, along with other specialty distributors, tailored our product offerings and service capabilities to meet the unique needs of that trade. Today, specialty distributors comprise the preferred distribution channel for wallboard and ceilings in both the commercial and residential construction markets.

        We believe the success of the specialty distribution model in wallboard and ceilings is driven by the strong value proposition provided to our customers. Given the logistical complexity of the distribution services we provide, the expertise needed to execute effectively, and the special equipment required, we believe specialty distributors focused on wallboard and ceilings are best suited to meet contractors' needs. The main drivers for our products are commercial new construction, commercial R&R, residential new construction and residential R&R.

Commercial

        Our addressable commercial construction market is composed of a variety of commercial and institutional sub-segments with varying demand drivers. Our commercial markets include offices, hotels, retail stores and other commercial buildings, while our institutional markets include educational facilities, healthcare facilities, government buildings and other institutional facilities. The principal demand drivers across these markets include the overall economic outlook, the general business cycle, government spending, vacancy rates, employment trends, interest rates, availability of credit and demographic trends.

        We believe commercial R&R spending is typically more stable than new commercial construction activity. Commercial R&R spending is driven by a number of factors, including commercial real estate prices and rental rates, office vacancy rates, government spending and interest rates. Commercial R&R spending is also driven by commercial lease expirations and renewals, as well as tenant turnover. Such events often result in repair, reconfiguration and/or upgrading of existing commercial space.

Residential

        Residential construction activity is driven by a number of factors, including the overall economic outlook, employment, income growth, home prices, availability of mortgage financing, interest rates and consumer confidence, among others.

        While residential R&R activity is typically more stable than new construction activity, we believe the prolonged period of under-investment during the recent downturn will result in above-average growth for the next several years. The primary drivers of residential R&R spending include changes in existing home prices, existing home sales, the average age of the housing stock, consumer confidence and interest rates.

Our Growth Strategy

        Our growth strategy entails taking market share within our existing footprint, expanding into new markets by opening new branches and strategic acquisitions. We expect to continue to capture profitable market share in our existing footprint by delivering industry-leading customer service. Our strategy for opening new branches is to further penetrate markets that are adjacent to our existing operations. Typically, we have pre-existing customer

6

Table of Contents

relationships in these markets but need a new location to fully capitalize on those relationships. Since the beginning of full year 2014, we have opened 21 new branches and we currently expect to open several new branches each year depending on market conditions. In addition, we will continue to selectively pursue tuck-in acquisitions and have a dedicated team of professionals to manage the process. Due to the large, highly fragmented nature of our market and our reputation throughout the industry, we believe we have the potential to access a robust acquisition pipeline that will continue to supplement our organic growth. We use a rigorous targeting process to identify acquisition candidates that will fit our culture and business model. As a result of our scale, purchasing power and ability to improve operations through implementing best practices, we believe we can achieve substantial synergies and drive earnings accretion from our acquisition strategy.

Customers

        Our diverse customer base consists of more than 20,000 contractors as well as home builders. We maintain local relationships with our contractors through our network of branches and our extensive salesforce. We also serve our large homebuilder customers through our local branches, but are able to coordinate the relationship on a national basis through our Yard Support Center in Tucker, Georgia. Our ability to serve multi-regional homebuilders across their footprint provides value to them and differentiates us from most of our competitors. During fiscal 2016 and fiscal 2015, our single largest customer accounted for 2% and 3%, respectively, of our net sales and our top ten customers accounted for 9% and 11%, respectively.

Suppliers

        Our leading market position, national footprint and superior service capabilities have allowed us to develop strong relationships with our suppliers. We maintain exceptional, long-term relationships with all seven major North American wallboard manufacturers, as well as the three major ceilings manufacturers: Armstrong, CertainTeed and USG. Because we account for a meaningful portion of their volumes and provide them with an extensive salesforce to market their products, we are viewed by our suppliers as a key channel partner. We believe this position provides us with advantaged procurement.

Sales and Marketing

        Our sales and marketing strategy is to provide a comprehensive set of high-quality products and superior services to contractors and builders reliably, safely, accurately and on-time. We have a highly experienced sales force of approximately 600 people who manage our customer relationships and grow our customer base. We have strategies to increase our customer base at both the corporate and local branch levels, which focus on building and growing strong relationships with our customers, whether they serve a small local market, or a national footprint. We believe that the experience and expertise of our salesforce differentiates us from our competition particularly in the commercial market, which requires a highly technical and specialized product knowledge and a sophisticated delivery plan.

Competition

        We compete against other specialty distributors as well as big box retailers and lumberyards. Among specialty distributors, we compete against a small number of large distributors and many small, local, privately-owned distributors. Our largest competitors include: Allied Building Products (a subsidiary of CRH plc), Foundation Building Materials, L&W Supply (a subsidiary of USG) and Winroc (a subsidiary of Superior Plus). However, we believe smaller, regional or local competitors still comprise approximately more than half of the North American specialty distribution market. The principal competitive factors in our business include, but are not limited to, availability of materials and supplies; technical product knowledge and expertise; advisory or other service capabilities; delivery capabilities; pricing of products; and availability of credit.

Table of Contents

Seasonality

        In a typical year, our operating results are impacted by seasonality. Historically, sales of our products have been slightly higher in the first and second quarters of each fiscal year due to favorable weather and longer daylight conditions during these periods. Seasonal variations in operating results may be impacted by inclement weather conditions, such as cold or wet weather, which can delay construction projects.

Intellectual Property

        We own United States trademark registrations for approximately 20 trademarks that we use in our business. Generally, registered trademarks have a perpetual life, provided that they are renewed on a timely basis and continue to be used properly as trademarks. We intend to maintain these trademark registrations as long as they remain valuable to our business. Other than certain of our local brands, the retention of which we believe helps maintain customer loyalty, we do not believe our business is dependent to a material degree on trademarks, patents, copyrights or trade secrets. In addition, other than commercially available software licenses, we do not believe that any of our licenses for third-party intellectual property are material to our business, taken as a whole.

Employees

        As of April 30, 2016, we had over 3,900 employees, of which less than 3% were affiliated with labor unions. We believe that we have good relations with our employees. Additionally, we believe that the training provided through our employee development programs and our entrepreneurial, performance-based culture provides significant benefits to our employees.

Government Regulation

        While we are not engaged in a "regulated industry," we are subject to various federal, state and local government regulations applicable to the business generally in the jurisdictions in which we operate, including laws and regulations relating to our relationships with our employees, public health and safety, work place safety, transportation, zoning and fire codes. We strive to operate each of our branches in accordance with applicable laws, codes and regulations. We believe we are in compliance in all material respects with existing applicable environmental laws and regulations and our employment, workplace health and workplace safety practices.

        Our operations in domestic interstate commerce are subject to the regulatory jurisdiction of the DOT, which has broad administrative powers with respect to our transportation operations. We are subject to safety requirements governing interstate operations prescribed by the DOT. Vehicle dimension and driver hours of service also are subject to both federal and state regulation. See Item 1A, "Risk Factors—Risks Relating to Our Business and Industry—Federal, state, local and other regulations could impose substantial costs and restrictions on our operations that would reduce our net income." Our operations are also subject to the regulatory jurisdiction of OSHA, which has broad administrative powers with respect to workplace and jobsite safety.

Environmental, Health and Safety

        We are subject to various federal, state and local environmental, health and safety laws and regulations, including laws and regulations governing the investigation and cleanup of contaminated properties, air emissions, water discharges, waste management and disposal, product safety and workplace health and safety. These laws and regulations impose a variety of requirements and restrictions on our operations and the products we distribute. The failure by us to comply with these laws and regulations could result in fines, penalties, enforcement actions, third party claims, damage to property or natural resources and personal injury, requirements to investigate or cleanup property or to pay for the costs of investigation or cleanup, or regulatory or judicial orders requiring corrective measures, including the installation of pollution control equipment or remedial actions and could negatively impact our reputation with customers. Environmental, health and safety laws and regulations applicable to our business, the products we distribute and the business of our customers, and the interpretation or enforcement of these laws and regulations, are constantly evolving and it is impossible to predict accurately the

8

Table of Contents

effect that changes in these laws and regulations, or their interpretation or enforcement, may have upon our business, financial condition or results of operations. Should environmental, health and safety laws and regulations, or their interpretation or enforcement, become more stringent, our costs, or the costs of our customers, could increase, which may have an adverse effect on our business, financial position, results of operations or cash flows.

        Under certain laws and regulations, such as the U.S. federal Superfund law or its state equivalents, the obligation to investigate, remediate, monitor and clean up contamination at a facility may be imposed on current and former owners, lessees or operators or on persons who may have sent waste to that facility for disposal. Liability under these laws and regulations may be imposed without regard to fault or to the legality of the activities giving rise to the contamination. Moreover, we may incur liabilities in connection with environmental conditions currently unknown to us relating to our prior, existing or future owned or leased sites or operations or those of predecessor companies whose liabilities we may have assumed or acquired.

Available Information

        We are subject to the informational requirements of the Exchange Act, and in accordance therewith, we file reports, proxy and information statements and other information with the SEC.

Item 1A.    Risk Factors

        The following risk factors may be important to understanding any statement in this Annual Report on Form 10-K or elsewhere. Our business, financial condition and operating results can be affected by a number of factors, whether currently known or unknown, including but not limited to those described below. Any one or more of such factors could directly or indirectly cause our actual results of operations and financial condition to vary materially from past or anticipated future results of operations and financial condition. Any of these factors, in whole or in part, could materially and adversely affect our business, financial condition, results of operations and stock price.

Risks Relating to Our Business and Industry

Our business is affected by general business, financial market and economic conditions, which could adversely affect our results of operations.

        Our business and results of operations are significantly affected by general business, financial market and economic conditions. General business, financial market and economic conditions that could impact the level of activity in the commercial and residential construction and the R&R markets include, among others, interest rate fluctuations, inflation, unemployment levels, tax rates, capital spending, bankruptcies, volatility in both the debt and equity capital markets, liquidity of the global financial markets, the availability and cost of credit, investor and consumer confidence, global economic growth, local, state and federal government regulation and the strength of regional and local economies in which we operate.

        There was a significant decline in economic growth, both in the United States and worldwide, that began in the second half of 2007 and continued through 2011. During this period, the U.S. construction markets we serve experienced unprecedented declines since the post-World War II era. There can be no guarantee that any improvement in these markets will be sustained or continue.

Table of Contents

Our sales are in part dependent upon the commercial new construction market and the commercial R&R market.

        The recent downturn in the U.S. commercial new construction market was one of the most severe of the last 40 years. Previously, such downturns in the construction industry have typically lasted about 2 to 3 years, resulting in market declines of approximately 20% to 40%, while the recent downturn in the commercial construction market lasted over 4 years, resulting in a market decline of approximately 60%. According to Dodge Data & Analytics, commercial construction put in place began to recover in 2013 and continued to increase 7% in 2015. However, 2015 levels of new commercial construction square footage put in place, measured by square footage of construction, are still well below the historical market average of 1.3 billion square feet annually since 1970. We cannot predict the duration of the current market conditions or the timing or strength of any future recovery of commercial construction activity in our markets. Continued weakness in the commercial construction market and the commercial R&R market, would have a significant adverse effect on our business, financial condition and operating results. Continued uncertainty about current economic conditions will continue to pose a risk to our business that serves the commercial construction and R&R markets as participants in this industry may postpone spending in response to tighter credit, negative financial news and/or declines in income or asset values, which could have a continued material negative effect on the demand for our products and services.

Our sales are also in part dependent upon the residential new construction market and home R&R activity.

        The distribution of our products, particularly wallboard, to contractors serving the residential market represents a significant portion of our business. Though its cyclicality has historically been somewhat moderated by R&R activity, wallboard demand is highly correlated with housing starts. Housing starts and R&R activity, in turn, are dependent upon a number of factors, including housing demand, housing inventory levels, housing affordability, foreclosure rates, geographical shifts in the population and other changes in demographics, the availability of land, local zoning and permitting processes, the availability of construction financing and the health of the economy and mortgage markets. Unfavorable changes in any of these factors beyond our control could adversely affect consumer spending, result in decreased demand for homes and adversely affect our business.

        Beginning in mid-2006 and continuing through late-2011, the homebuilding industry experienced a significant downturn. This decrease in homebuilding activity led to a steep decline in wallboard demand which, in turn, had a significant adverse effect on our business during this time. According to the U.S. Census Bureau, 1.1 million housing units were started in 2015, representing an increase of 10% from 2014. Nevertheless, housing starts in 2015 remained significantly below their historical long-term average. In addition, some analysts project that the demand for residential construction may be negatively impacted as the number of renting households has increased in recent years and a shortage in the supply of affordable housing is expected to result in lower home ownership rates. The timing and extent of a recovery, if any, in homebuilding and the resulting impact on demand for our products are uncertain. Further, even if homebuilding activity fully recovers, the impact of such recovery on our business may be suppressed if, for example, the average selling price or average size of new single family homes decreases, which could cause homebuilders to decrease spending on our services and the products we distribute.

        Beginning in 2007, the mortgage markets were also substantially disrupted as a result of increased defaults, primarily due to weakened credit quality of homeowners. In reaction to the disruption in the mortgage markets, stricter regulations and financial requirements were adopted and the availability of mortgages for potential homebuyers was significantly reduced as a result of a limited credit market and stricter standards to qualify for mortgages. Mortgage financing and commercial credit for smaller homebuilders, as well as for the development of new residential lots, continue to be constrained. If the residential construction industry continues to experience weakness and a reduction in activity, our business, financial condition and operating results will be significantly and adversely affected.

        We also rely, in part, on home R&R activity. High unemployment levels, high mortgage delinquency and foreclosure rates, lower home prices, limited availability of mortgage and home improvement financing and significantly lower housing turnover, may restrict consumer spending, particularly on discretionary items such as

10

Table of Contents

home improvement projects, and affect consumer confidence levels leading to reduced spending in the R&R end markets. We cannot predict the timing or strength of a significant recovery in R&R activity, if any. Furthermore, without a significant recovery of the general economy, consumer preferences and purchasing practices and the strategies of our customers may adjust in a manner that could result in changes to the nature and prices of products demanded by the end consumer and our customers and could adversely affect our business and results of operations.

Our industry and the markets in which we operate are highly fragmented and competitive, and increased competitive pressure may adversely affect our results.

        We currently compete in the wallboard, ceilings and complementary interior construction products distribution markets primarily with smaller distributors, but we also face competition from a number of national and multi-regional distributors of building materials, some of which are larger and have greater financial resources than us.

        Competition varies depending on product line, type of customer and geographic area. If our competitors have greater financial resources, they may be able to offer higher levels of service or a broader selection of inventory than we can. As a result, we may not be able to continue to compete effectively with our competitors. Any of our competitors may (i) foresee the course of market development more accurately than we do, (ii) provide superior service and sell or distribute superior products, (iii) have the ability to supply or deliver similar products and services at a lower cost, (iv) develop stronger relationships with our customers and other consumers in the industry in which we operate, (v) adapt more quickly to evolving customer requirements than we do, (vi) develop a superior network of distribution centers in our markets or (vii) access financing on more favorable terms than we can obtain. As a result, we may not be able to compete successfully with our competitors.

        Competition can also reduce demand for our products, negatively affect our product sales or cause us to lower prices. The consolidation of homebuilders may result in increased competition for their business. Certain product manufacturers that sell and distribute their products directly to homebuilders may increase the volume of such direct sales. Our suppliers may also elect to enter into exclusive supplier arrangements with other distributors.

        Our customers consider the performance of the products we distribute, our customer service and price when deciding whether to use our services or purchase the products we distribute. Excess industry capacity for certain products in several geographic markets could lead to increased price competition. We may be unable to maintain our operating costs or product prices at a level that is sufficiently low for us to compete effectively. If we are unable to compete effectively with our existing competitors or new competitors enter the markets in which we operate, our financial condition, operating results and cash flows may be adversely affected.

We are subject to significant pricing pressures.

        Large contractors and homebuilders in both the commercial and residential industries have historically been able to exert significant pressure on their outside suppliers and distributors to keep prices low in the highly fragmented building products supply and services industry. The recent construction industry downturn significantly increased the pricing pressures from homebuilders and other customers. In addition, continued consolidation in the commercial and residential industries and changes in builders' purchasing policies and payment practices could result in even further pricing pressure. A decline in the prices of the products we distribute could adversely impact our operating results. When the prices of the products we distribute decline, customer demand for lower prices could result in lower sales prices and, to the extent that our inventory at the time was purchased at higher costs, lower margins. Alternatively, due to the rising market price environment, our suppliers may increase prices or reduce discounts on the products we distribute and we may be unable to pass on any cost increase to our customers, thereby resulting in reduced margins and profits. Overall, these pricing pressures may adversely affect our operating results and cash flows.

The trend toward consolidation in our industry may negatively impact our business.

        Customer demands and supplier capabilities have resulted in consolidation in our industry, which could cause markets to become more competitive as greater economies of scale are achieved by distributors that are able to efficiently expand their operations. We believe these customer demands could result in fewer overall distributors operating multiple locations. There can be no assurance that we will be able to effectively take advantage of this trend toward consolidation which may make it more difficult for us to maintain operating margins and could also increase the competition for acquisition targets in our industry, resulting in higher acquisition costs and prices.

We may be unable to successfully implement our growth strategy, which includes pursuing strategic acquisitions and opening new branches.

        Our long-term business strategy depends in part on increasing our sales and growing our market share through strategic acquisitions and opening new branches. If we fail to identify and acquire suitable acquisition targets on appropriate terms, our growth strategy may be materially and adversely affected. Further, if our operating results decline as a result of reduced activity in the residential or commercial construction markets, we may be unable to obtain the capital required to effect new acquisitions or open new branches.

        In addition, we may not be able to integrate the operations of future acquired businesses in an efficient and cost-effective manner or without significant disruption to our existing operations. Moreover, acquisitions involve significant risks and uncertainties, including uncertainties as to the future financial performance of the acquired business, difficulties integrating acquired personnel and corporate cultures into our business, the potential loss of key employees, customers or suppliers, difficulties in integrating different computer and accounting systems, exposure to unknown or unforeseen liabilities of acquired companies, difficulties implementing disclosure controls and procedures and internal control over financial reporting for the acquired businesses, and the diversion of management attention and resources from existing operations. We may be unable to successfully complete potential acquisitions due to multiple factors, such as issues related to regulatory review of the proposed transactions. We may also be required to incur additional debt in order to consummate acquisitions in the future, which debt may be substantial and may limit our flexibility in using our cash flow from operations. Our failure to integrate future acquired businesses effectively or to manage other consequences of our acquisitions, including increased indebtedness, could prevent us from remaining competitive and, ultimately, could adversely affect our financial condition, operating results and cash flows.

        In addition, if we finance acquisitions by issuing our equity securities or securities convertible into our equity securities, our existing stockholders would be diluted, which, in turn, could adversely affect the market price of our common stock. We could also finance an acquisition with debt, resulting in higher leverage and interest costs relating to the acquisition. As a result, if we fail to evaluate and execute acquisitions efficiently, we may not ultimately experience the anticipated benefits of the acquisitions, and we may incur costs that exceed our expectations.

We may not be able to expand into new geographic markets, which may impact our ability to grow our business.

        We intend to continue to pursue our growth strategy to expand into new geographic markets for the foreseeable future. Our expansion into new geographic markets may present competitive, distribution and other challenges that differ from the challenges we currently face. In addition, we may be less familiar with the customers in these markets and may ultimately face different or additional risks, as well as increased or unexpected costs, compared to those we experience in our existing markets. Expansion into new geographic markets may also expose us to direct competition with companies with whom we have limited or no past experience as competitors. To the extent we rely upon expanding into new geographic markets and do not meet, or are unprepared for, any 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 negatively affected.

Product shortages, loss of key suppliers or failure to develop relationships with qualified suppliers, and our dependence on third-party suppliers and manufacturers could affect our financial health.

        We distribute wallboard, ceilings and related specialty building materials that are manufactured by a number of major suppliers. Our ability to offer a wide variety of products to our customers is dependent upon our ability to obtain adequate product supply from manufacturers and other suppliers. Generally, the products we distribute are obtainable from various sources and in sufficient quantities. Any disruption in our sources of supply, particularly of the most commonly sold items, could result in a loss of revenues, reduced margins and damage to our relationships with customers. Supply shortages may occur as a result of unanticipated increases in demand, shortage of raw materials or difficulties in production or delivery. When shortages occur, our suppliers often allocate products among distributors. The loss of, or a substantial decrease in the availability of, products from our suppliers or the loss of key supplier arrangements, such as those whereby we are afforded exclusive distribution rights in certain geographic areas, could adversely impact our financial condition, operating results and cash flows. For example, if our relationship with Armstrong were to be damaged or lost, our financial condition, operating results and cash flows may suffer.

        Our ability to maintain relationships with qualified suppliers who can satisfy our high standards for quality and our need to be supplied with products in a timely and efficient manner is a significant challenge. Our suppliers' ability to provide us with products can also be adversely affected in the event they become financially unstable, particularly in light of continuing economic difficulties in various regions of the United States and the world, fail to comply with applicable laws, encounter supply disruptions, shipping interruptions or increased costs, or they become faced with other factors beyond our control.

        Although in many instances we have agreements with our suppliers, these agreements are generally terminable by either party on limited notice. If market conditions change, suppliers may stop offering us favorable terms. Failure by our suppliers to continue to supply us with products on favorable terms, commercially reasonable terms, or at all, could put pressure on our operating margins or have a material adverse effect on our financial condition, operating results and cash flows.

The commercial and residential construction markets are seasonal.

        The markets in which we operate are seasonal. Although weather patterns affect our operating results throughout the year, the months of November through February have historically been, and are generally expected to continue to be, adversely affected by weather patterns in some of our markets, causing reduced commercial and residential construction activity. We experience seasonal variation as a result of our customers' dependence on suitable weather to engage in construction, R&R projects. For example, during the winter months, construction activity generally declines due to inclement weather and shorter daylight hours. In addition, to the extent that hurricanes, severe storms, earthquakes, floods, fires, other natural disasters or similar events occur in the markets in which we operate, our business may be adversely affected. As a result, our operating results have historically varied significantly between fiscal quarters, and we anticipate that we will continue to experience these quarterly fluctuations in the future.

The loss of any of our significant customers or a reduction in the quantity of products they purchase could affect our financial health.

        Our ten largest customers generated approximately 9.0%, 10.6% and 11.1% of our net sales in the aggregate for fiscal 2016, fiscal 2015 and full year 2014, respectively. We cannot guarantee that we will maintain or improve our relationships with these customers, or successfully assume the customer relationships of any businesses that we acquire, or that we will continue to supply these customers at historical levels. Due to the weak housing market in recent years in comparison to long-term averages, many of our homebuilder customers substantially reduced their construction activity. Some of our homebuilder customers exited or severely curtailed building activity in certain of our markets.

        In addition, professional homebuilders, commercial builders and other customers may: (i) purchase some of the products that we currently sell and distribute directly from manufacturers; (ii) elect to establish their own building products manufacturing and distribution facilities or (iii) give advantages to manufacturing or distribution intermediaries in which they have an economic stake. Continued consolidation among professional homebuilders and commercial builders 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 or deterioration in our existing relationships with any of our customers could adversely affect our financial condition, operating results and cash flows. Furthermore, our customers typically are not required to purchase any minimum amount of products from us. Should our customers purchase the products we distribute in significantly lower quantities than they have in the past, or should the customers of any businesses that we acquire purchase products from us in significantly lower quantities than they had prior to our acquisition of the business, such decreased purchases could have a material adverse effect on our financial condition, operating results and cash flows.

We are exposed to product liability, warranty, casualty, construction defect, contract, tort, employment and other claims and legal proceedings related to our business, the products we distribute, the services we provide and services provided for us by third parties.

        In the ordinary course of business, we are subject to various claims and litigation. Any such claims, whether with or without merit, could be time consuming and expensive to defend and could divert management's attention and resources. The building materials industry has been subject to personal injury and property damage claims arising from alleged exposure to raw materials contained in building products as well as claims for incidents of catastrophic loss, such as building fires. As a distributor of building materials, we face an inherent risk of exposure to product liability claims in the event that the use of the products we have distributed in the past or may in the future distribute is alleged to have resulted in economic loss, personal injury or property damage or violated environmental, health or safety or other laws. Such product liability claims have included and may in the future include allegations of defects in manufacturing, defects in design, a failure to warn of dangers inherent in the product, negligence, strict liability or a breach of warranties. In particular, certain of our subsidiaries have been the subject of claims related to alleged exposure to asbestos-containing products they distributed prior to 1979, which have not materially impacted our financial condition or operating results. See "Item 3, Legal Proceedings." We are also from time to time subject to casualty, contract, tort and other claims relating to our business, the products we have distributed in the past or may in the future distribute, and the services we have provided in the past or may in the future provide, either directly or through third parties. If any such claim were adversely determined, our financial condition, operating results and cash flows could be adversely affected if we were unable to seek indemnification for such claims or were not adequately insured for such claims. We rely on manufacturers and other suppliers to provide us with the products we sell or distribute. Since we do not have direct control over the quality of products that are manufactured or supplied to us by third-parties, we are particularly vulnerable to risks relating to the quality of such products. In addition, we are exposed to potential claims arising from the conduct of our employees, builders and their subcontractors, and third-party installers for which we may be liable. We and they are subject to regulatory requirements and risks applicable to general contractors, which include management of licensing, permitting and quality of third-party installers. As they apply to our business, if we fail to manage these processes effectively or provide proper oversight of these services, we could suffer lost sales, fines and lawsuits, as well as damage to our reputation, which could adversely affect our business and the results of our operations.

        In addition, claims and investigations may arise related to distributor relationships, commercial contracts, antitrust or competition law requirements, employment matters, employee benefits issues and other compliance and regulatory matters, including anti-corruption and anti-bribery matters. While we have processes and policies designed to mitigate these risks and to investigate and address such claims as they arise, we cannot predict or, in some cases, control the costs to defend or resolve such claims.

        Although we believe we currently maintain suitable and adequate insurance in excess of our self-insured amounts, there can be no assurance that we will be able to maintain such insurance on acceptable terms or that such insurance will provide adequate protection against potential liabilities, and the cost of any product liability, warranty, casualty, construction defect, contract, tort, employment or other litigation or other proceeding, even if resolved in our favor, could be substantial. Additionally, we do not carry insurance for all categories of risk that our business may encounter. Any significant uninsured liability may require us to pay substantial amounts. There can be no assurance that any current or future claims will not adversely affect our financial position, cash flows or results of operations.

Our operations are subject to various hazards that may cause personal injury or property damage and increase our operating costs, and which may exceed the coverage of our insurance.

        There are inherent risks to our operations. Our delivery employees are subject to the usual hazards associated with providing services on construction sites, while our distribution center personnel are subject to the hazards associated with moving and storing large quantities of heavy materials. In addition, we employ approximately 1,200 drivers in connection with our distribution operations and, from time to time, these drivers are involved in accidents which may cause injuries and in which goods carried by these drivers may be lost or damaged. Our trucks with articulating boom loaders, particularly when loaded, expose our drivers and others to traffic hazards.

        Operating hazards can cause personal injury and loss of life, damage to or destruction of property, building and equipment and environmental damage, and we cannot eliminate these risks. We maintain vehicle and commercial insurance to cover property damages and personal injuries resulting from traffic accidents, and rely on state mandated social insurance for work-related injuries of our employees. Nevertheless, any claim that exceeds the scope of our insurance coverage, if successful and of sufficient magnitude, could result in the incurrence of substantial costs and the diversion of resources, which could have a material adverse effect on us. A material increase in the frequency or severity of accidents, claims for lost or damaged goods, liability claims, workers' compensation claims, or unfavorable resolutions of any such claims could also adversely affect our results of operations to the extent such claims are not covered by our insurance or such losses exceed our reserves. Further, significant increases in insurance costs or the inability to purchase insurance as a result of these claims could reduce our profitability and have an adverse effect on our results of operations. The timing of the incurrence of these costs could significantly and adversely impact our operating results compared to prior periods.

Failure to attract and retain key employees could have a significant adverse effect on our business.

        Our success depends to a large extent on our ability to attract, hire, train and retain qualified managerial, operational, sales and other personnel. We face significant competition for qualified and experienced employees in our industry and from other industries and, as a result, we may be unable to attract and retain the personnel needed to successfully conduct and grow our operations. Additionally, key personnel, including members of management and our sales team with key customer relationships, may leave and compete against us.

        Our continued success also depends to a significant degree on the continued service of our senior management team. With an average of over 25 years of experience in the building products distribution sector, our senior management team has been integral to our successful acquisition and integration of businesses to grow our market share. The loss of any member of our senior management team or other experienced, senior employees or sales team members could significantly impair our ability to execute our business plan, cause us to lose customers and reduce our net sales, or lead to challenges with employee morale and the loss of other key employees. In any such event, our financial condition, operating results and cash flows could be adversely affected.

        Additionally, the recent downturn in the general economy and the markets we serve resulted in a reduction of the workforce in the construction industry. There can be no assurance that we or our customers will be able to efficiently attract employees as activity in the markets we serve returns to historical levels. As a result, we and our customers may experience higher costs in attracting and retaining such employees. Any significant increases in these costs may have an adverse effect on our financial position, cash flows or results of operations.

Higher health care costs and labor costs could adversely affect our business.

        As a result of the passage in 2010 of the U.S. Patient Protection and Affordable Care Act, or the ACA, we are required to provide affordable coverage, as defined in the ACA, to all employees, or otherwise be subject to a payment per employee based on the affordability criteria in the ACA. Additionally, some states and localities have passed state and local laws mandating the provision of certain levels of health benefits by some employers. Increased health care and insurance costs as well as other changes in federal or state workplace regulations could have a material adverse effect on our business, financial condition and results of operations.

        Various federal and state labor laws govern our relationships with our employees and affect our operating costs. These laws include employee classifications as exempt or non-exempt, minimum wage requirements, unemployment tax rates, workers' compensation rates, overtime, family leave, safety standards, payroll taxes, citizenship requirements and other wage and benefit requirements for employees classified as non-exempt. As our employees may be paid at rates that relate to the applicable minimum wage, further increases in the minimum wage could increase our labor costs. Significant additional government regulations could materially affect our business, financial condition and results of operations.

        In addition, we compete with other companies for many of our employees in hourly positions, and we invest significant resources to train and motivate our employees to maintain a high level of job satisfaction. Our hourly employment positions have historically had high turnover rates, which can lead to increased spending on training and retention and, as a result, increased labor costs. If we are unable to effectively retain highly qualified employees in the future, it could adversely impact our operating results.

The majority of our net sales are credit sales that 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 or timely 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. We 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 construction project where we establish a security interest in the material used in the project. The type of credit we offer depends both on the customer's financial strength and the nature of the business in which the customer is involved. End users, resellers and other non-contractor customers typically purchase more on unsecured credit than secured credit. If any of our customers are unable to repay credit that we have extended in a timely manner, or at all, our financial condition, operating results and cash flows would be adversely affected. Further, our collections efforts with respect to non-paying or slow-paying customers could negatively impact our customer relations going forward.

        Because we depend on certain of our customers to repay extensions of credit, if the financial condition of our customers declines, our credit risk could increase as a result. Significant contraction in the commercial and residential construction markets, coupled with limited credit availability and stricter financial institution underwriting standards, could adversely affect the operations and financial stability of 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.

We occupy many of our facilities under long-term non-cancellable leases, and we may be unable to renew our leases at the end of their terms.

        Many of our facilities and distribution centers are located on leased premises subject to non-cancellable leases. Typically, our leases have initial terms ranging from three to five years, with options to renew for specified periods of time. We believe that our future leases will likely also be long-term and non-cancellable and have similar renewal options. If we close or stop fully utilizing a facility, we will most likely remain obligated to perform under the applicable lease, which would include, among other things, making the base rent payments, and paying insurance, taxes and other expenses on the leased property for the remainder of the lease term. Our future

16

Table of Contents

minimum aggregate rental commitments for leases for our facilities and distribution centers, as of April 30, 2016, is approximately $69.3 million of which $68.0 million is not reflected as liabilities on our balance sheet. Our inability to terminate a lease when we stop fully utilizing a facility or exit a geographic market can have a significant adverse impact on our financial condition, operating results and cash flows.

        In addition, at the end of the lease term and any renewal period for a facility, we may be unable to renew the lease without substantial additional cost, if at all. If we are unable to renew our facility leases, we may close or relocate a facility, which could subject us to construction and other costs and risks, which in turn could have a material adverse effect on our business and operating results. Further, we may not be able to secure a replacement facility in a location that is as commercially viable, including access to rail service, as the lease we are unable to renew. Having to close a facility, even briefly to relocate, would reduce the sales that such facility would have contributed to our revenues. Additionally, a relocated facility may generate less revenue and profit, if any, than the facility it was established to replace.

Our operating results and financial position could be negatively impacted by accounting policies, rules and regulations.

        Our operating results and financial position could be negatively impacted by implementation of our various accounting policies as well as changes to accounting rules and regulations or new interpretations of existing accounting standards. For example, while we are still evaluating the impact of our pending adoption of ASU No. 2016-02, "Leases" on our consolidated financial statements, we expect that upon adoption we will recognize right of use, or ROU, assets and liabilities that could be material to our financial statements. In addition, from time to time we could incur impairment charges that adversely affect our operating results. For example, changes in economic or operating conditions impacting our estimates and assumptions could result in the impairment of intangible assets (such as goodwill) or long-lived assets in accordance with applicable accounting guidance. In the event that we determine our intangible or long-lived assets are impaired, we may be required to record a significant charge to earnings in our financial statements that could have a material adverse effect on our results of operations.

We may be unable to effectively manage our inventory and working capital as our sales volume increases or the prices of the products we distribute fluctuate, which could have a material adverse effect on our business, financial condition and operating results.

        We purchase certain products, including wallboard, ceilings, steel framing and other specialty building materials, from manufacturers which are then sold and distributed to customers. We must maintain, and have adequate working capital to purchase, sufficient inventory to meet customer demand. Due to the lead times required by our suppliers, we order products in advance of expected sales. As a result, we are required to forecast our sales and purchase accordingly. In periods characterized by significant changes in economic growth and activity in the commercial and residential building and home R&R industries, it can be especially difficult to forecast our sales accurately. We must also manage our working capital to fund our inventory purchases. Excessive increases in the market prices of certain building products, such as wallboard, ceilings and steel framing, can put negative pressure on our operating cash flows by requiring us to invest more in inventory. In the future, if we are unable to effectively manage our inventory and working capital as we attempt to expand our business, our cash flows may be negatively affected, which could have a material adverse effect on our business, financial condition and operating results.

The agreements that govern our indebtedness contain various financial covenants that could limit our ability to engage in activities that may be in our best long-term interests.

        The agreements that govern our indebtedness include covenants that, among other things, may impose significant operating and financial restrictions, including restrictions on our ability to engage in activities that may be in our best long-term interests. These covenants may restrict our ability to:

•

incur additional indebtedness;

17

Table of Contents

•

create or maintain liens on property or assets;



•

make investments, loans and advances;



•

sell certain assets or engage in acquisitions, mergers or consolidations;



•

redeem debt;



•

pay dividends and distributions; and



•

enter into transactions with affiliates.

        In addition, under the terms of our senior secured asset based revolving credit facility, or the ABL Facility, we may at times be required to comply with a specified fixed charge coverage ratio. Our ability to meet this ratio could be affected by events beyond our control, and we cannot assure that we will meet this ratio.

        A breach of any of the covenants under any of our debt agreements would result in a default under such agreement. If any such default occurs, the administrative agent under the agreement would be entitled to take various actions, including the acceleration of amounts due under the agreement and all actions permitted to be taken by a secured creditor. This could have serious adverse consequences on our financial condition and could cause us to become insolvent.

Our current indebtedness, degree of leverage and any future indebtedness we may incur, may adversely affect our cash flow, limit our operational and financing flexibility and negatively impact our business and our ability to make payments on our indebtedness and declare dividends and make other distributions.

        Our subsidiary, GYP Holdings III Corp., entered into the ABL Facility, a senior secured first lien term loan facility, or the First Lien Facility, and the Second Lien Facility in connection with the Acquisition. As of April 30, 2016, $101.9 million was outstanding under the ABL Facility and $187.2 million was available for future borrowings under the ABL Facility. In addition, we had $382.2 million outstanding under the First Lien Facility and $160.0 million outstanding under the Second Lien Facility. We used the net proceeds from our IPO together with cash on hand to repay $160.0 million principal amount of our term loan debt outstanding under the Second Lien Facility, which was a payment in full of the entire loan balance due under the Second Lien Facility. See also Item 7, "Management's Discussion and Analysis of Financial Condition and Results of Operations—Recent Events." We may incur substantial additional debt in the future. The ABL Facility, the First Lien Facility and other debt instruments we may enter into in the future, may have significant consequences to our business and, as a result, may impact our stockholders, including:

•

impairing our ability to obtain additional financing for working capital, capital expenditures, acquisitions or general corporate purposes;



•

requiring us to dedicate a significant portion of our cash flows from operations to pay interest on any outstanding indebtedness, which would reduce the funds available to us for operations and other purposes;



•

limiting our flexibility in planning for, or reacting to, changes in our business, the industries in which we operate;



•

making it more difficult for us to satisfy our obligations with respect to our indebtedness;



•

making us more vulnerable to adverse changes in general economic, industry and competitive conditions and adverse changes in government regulation;



•

placing us at a competitive disadvantage compared to our competitors that are less leveraged and, therefore, more able to take advantage of opportunities that our leverage prevents us from exploiting;



•

impairing our ability to refinance existing indebtedness or borrow additional amounts for working capital, capital expenditures, acquisitions, debt service requirements, execution of our business strategy or other purposes;



•

restricting our ability to pay dividends and make other distributions; and



•

adversely affecting our credit ratings.

        Any of the above listed factors could materially adversely affect our financial condition, liquidity or results of operations.

        Furthermore, we expect that we will depend primarily on cash generated by our operations in order to pay our expenses and any amounts due under our existing indebtedness and any future indebtedness we may incur. As a result, our ability to repay our indebtedness depends on the future performance of our business, which will be affected by financial, business, economic and other factors, many of which we cannot control. Our business may not generate sufficient cash flows from operations in the future and we may not achieve our currently anticipated growth in revenues and cash flows, either or both of which could result in our being unable to repay indebtedness or to fund other liquidity needs. If we do not have enough funds, we may be required to refinance all or part of our then existing indebtedness, sell assets or borrow additional funds, in each case on terms that may not be acceptable to us, if at all. In addition, the terms of existing or future debt agreements, including our existing ABL Facility, may restrict us from engaging in any of these alternatives. Our ability to recapitalize and incur additional debt in the future could also delay or prevent a change in control of our Company, make certain transactions more difficult to complete or impose additional financial or other covenants on us.

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, including secured debt. 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, the ABL Facility provides a commitment of up to $300.0 million, subject to a borrowing base. As of April 30, 2016, we are able to borrow an additional $187.2 million under the ABL Facility. If new debt is added to our current debt levels, the related risks that we now face could intensify. See also Item 7, "Management's Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources—Our Credit Facilities."

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

        A significant portion of our outstanding debt bears interest at variable rates. We have entered into an interest rate cap on three-month U.S. dollar LIBOR, which effectively caps the interest rate at 5.75% on an initial notional amount of $275.0 million of our variable rate debt obligation under the First Lien Facility, or any replacement facility with similar terms. However, increases in interest rates with respect to any amount of our debt not covered by the interest rate cap could increase the cost of servicing our debt and could materially reduce our profitability and cash flows. Excluding the effect of the interest rate cap and the interest rate floor on the First Lien Facility, each 1% increase in interest rates on the First Lien Facility would increase our annual interest expense by approximately $3.8 million based on balances outstanding under the First Lien Facility as of April 30, 2016. Assuming the ABL Facility was fully drawn up to the $300.0 million maximum commitment, each 1% increase in interest rates would result in a $3.0 million increase in annual interest expense on the ABL Facility. The impact of increases in interest rates could be more significant for us than it would be for some other comparable companies because of our substantial indebtedness.

We incurred net losses in recent periods and we may experience net losses in the future.

        We experienced net losses of $11.7 million, $19.0 million and $200.9 million for fiscal 2015, the one month ended April 30, 2014 and the eleven months ended March 31, 2014, respectively. There is no guarantee that we will be successful in realizing or sustaining net income or otherwise achieving profitability or sustaining positive Adjusted EBITDA and operating cash flow in future periods. Any failure to achieve or sustain net income or sustain positive Adjusted EBITDA and operating cash flow could, among other things, impair our ability to complete future financings, increase the cost of obtaining financing or force us to seek additional capital through

19

sales of our equity securities, which could dilute the value of our common stock. In addition, a lack of profitability could adversely affect the price of our common stock.

We may have future capital needs that require us to incur additional debt and may be unable to obtain additional financing on acceptable terms, if at all.

        We rely substantially on the liquidity provided by our existing ABL Facility and cash on hand to provide working capital and fund our operations. Our working capital and capital expenditure requirements are likely to grow as the commercial and residential construction markets improve and we execute our strategic growth plan. Economic and credit market conditions, the performance of the commercial and residential construction markets, and our financial performance, 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, economic conditions and financial, business and other factors, many of which are beyond our control. The prolonged continuation or worsening of current housing market conditions and the macroeconomic factors that affect our industry could require us to seek additional capital and have a material adverse effect on our ability to secure such capital on favorable terms, if at all.

        We may be unable to secure additional financing or financing on favorable terms or our operating cash flow may be insufficient to satisfy our financial obligations under our outstanding indebtedness. If additional funds are raised through the issuance of additional equity or convertible debt securities, our stockholders may experience significant dilution. We may also incur additional indebtedness in the future, including secured debt, subject to the restrictions contained in the ABL Facility and the First Lien Facility. If new debt is added to our current debt levels, the related risks that we now face could intensify.

Because we are a holding company with no operations of our own, we are financially dependent on receiving distributions from our subsidiaries and we could be harmed if such distributions could not be made in the future.

        We are a holding company and all of our operations are conducted through subsidiaries. Consequently, we rely on payments or distributions from our subsidiaries. We do not currently expect to declare or pay dividends on our common stock for the foreseeable future; however, to the extent that we determine in the future to pay dividends on our common stock, we will be dependent on our subsidiaries to make funds available to us for the payment of such dividends. The ability of such subsidiaries to pay dividends or make other payments or distributions to us is subject to applicable local law. Such laws and restrictions could limit the payment of dividends and distributions to us, which would restrict our ability to continue operations. In addition, the terms of the agreements governing the ABL Facility and the First Lien Facility restrict the ability of our subsidiaries to pay dividends, make loans or otherwise transfer assets to us. Furthermore, our subsidiaries are permitted under the terms of the ABL Facility and the First Lien Facility to incur additional indebtedness that may restrict or prohibit the making of distributions, the payment of dividends or the making of loans by such subsidiaries to us.

        Some of our subsidiaries sponsor deferred compensation arrangements that entitle selected employees of those subsidiaries to participate in increases in the adjusted book value of a specified number of shares of common stock of those subsidiaries. Employees participate in these arrangements through cash-based stock appreciation rights, by holding common stock of the applicable subsidiary and/or through deferred compensation programs. As of April 30, 2016, we have reflected an aggregate fair value of $50.4 million of liabilities related to these compensation arrangements on our consolidated balance sheets, of which $2.1 million is classified as a current liability and the remainder is classified as a long-term liability. Upon termination of employment of those with whom we have these arrangements, these subsidiaries are required to make payments to these individuals. Settlements of these awards are typically made with cash or through execution of an installment note payable to the employee typically over a period of four to five years. Any requirement to make payments to employees pursuant to these deferred compensation arrangements could impact the cash flows of these subsidiaries and their ability to make funds available to us.

An impairment of goodwill could have a material adverse effect on our results of operations.

        Acquisitions frequently result in the recording of goodwill and other intangible assets. At April 30, 2016, goodwill represented 30.9% of our total assets. Goodwill is not amortized and is subject to impairment testing at least annually using a fair value based approach. The identification and measurement of goodwill impairment involves the estimation of the fair value of our reporting units, which are consistent with our operating segments. The estimates of fair value of reporting units are based on the best information available as of the date of the assessment and incorporate management assumptions about expected future cash flows and other valuation techniques. Future cash flows can be affected by changes in industry or market conditions, among other factors. The recoverability of goodwill is evaluated at least annually and when events or changes in circumstances indicate that the fair value of a reporting unit has more likely than not declined below its carrying value. The annual impairment test resulted in no impairment of goodwill during fiscal 2016, fiscal 2015 or full year 2014.

        We cannot accurately predict the amount and timing of any impairment of assets, and, in the future, we may be required to take additional goodwill or other asset impairment charges relating to certain of our reporting units. Any such non-cash charges would have an adverse effect on our financial results.

Federal, state, local and other regulations could impose substantial costs and restrictions on our operations that would reduce our net income.

        We are subject to various federal, state, local and other laws and regulations, including, among other things, transportation regulations promulgated by the U.S. Department of Transportation, or the DOT, work safety regulations promulgated by the Occupational Safety and Health Administration, or OSHA, employment regulations promulgated by the U.S. Equal Employment Opportunity Commission, regulations of the U.S. Department of Labor, accounting standards issued by the Financial Accounting Standards Board or similar entities, and state and local zoning restrictions, building codes and contractors' licensing regulations. More burdensome regulatory requirements in these or other areas may increase our general and administrative costs and adversely affect our financial condition, operating results and cash flows. Moreover, failure to comply with the regulatory requirements applicable to our business could expose us to litigation and substantial fines and penalties that could adversely affect our financial condition, operating results and cash flows.

        Our transportation operations, upon which we depend to distribute products from our distribution centers, are subject to the regulatory jurisdiction of the DOT, which has broad administrative powers with respect to our transportation operations. Vehicle dimensions and driver hours of service also are subject to both federal and state regulation. More restrictive limitations on vehicle weight and size, trailer length and configuration, or driver hours of service would increase our costs, which, if we are unable to pass these cost increases on to our customers, may increase our selling, general and administrative expenses and adversely affect our financial condition, operating results and cash flows. If we fail to comply adequately with the DOT regulations or regulations become more stringent, we could experience increased inspections, regulatory authorities could take remedial action including imposing fines or shutting down our operations or we could be subject to increased audit and compliance costs. If any of these events were to occur, our financial condition, operating results and cash flows would be adversely affected.

        In addition, the commercial and residential construction industries are subject to various local, state and federal statutes, ordinances, codes, rules and regulations concerning zoning, building design and safety, construction, contractor licensing, energy conservation and similar matters, including regulations that impose restrictive zoning and density requirements on the residential new construction industry or that limit the number of homes or other buildings that can be built within the boundaries of a particular area. Regulatory restrictions may increase our operating expenses and limit the availability of suitable building lots for our customers, any of which could negatively affect our business, financial condition and results of operations.

Compliance with environmental, health and safety laws and regulations could be expensive. Failure to comply with environmental, health and safety laws and regulations could subject us to significant liability.

        We are subject to various federal, state and local environmental, health and safety laws and regulations, including laws and regulations governing the investigation and cleanup of contaminated properties, air emissions, water discharges, waste management and disposal, product safety and the health and safety of our employees and customers. These laws and regulations impose a variety of requirements and restrictions on our operations and the products we distribute. Our failure to comply with these laws and regulations could result in fines, penalties, enforcement actions, third party claims, damage to property or natural resources and personal injury, requirements to investigate or cleanup property or to pay for the costs of investigation or cleanup, or regulatory or judicial orders requiring corrective measures, including the installation of pollution control equipment or remedial actions and could negatively impact our reputation with customers. Environmental, health and safety laws and regulations applicable to our business, the products we distribute and the business of our customers, and the interpretation or enforcement of these laws and regulations, are constantly evolving and it is difficult to accurately predict the effect that changes in these laws and regulations, or their interpretation or enforcement, may have upon our business, financial condition or results of operations. Should environmental, health and safety laws and regulations, or their interpretation or enforcement, become more stringent, our costs, or the costs of our customers, could increase, which may have an adverse effect on our business, financial position, results of operations or cash flows.

        Under certain environmental laws and regulations, such as the U.S. federal Superfund law or its state equivalents, the obligation to investigate, remediate, monitor and clean up contamination at a facility may be imposed on current and former owners, lessees or operators or on persons who may have sent waste to that facility for disposal. Liability under these laws and regulations may be imposed without regard to fault or to the legality of the activities giving rise to the contamination. Contamination has been identified at several of our current and former facilities, and we have incurred and will continue to incur costs to investigate, remediate, monitor and otherwise address these conditions. Moreover, we may incur liabilities in connection with environmental conditions currently unknown to us relating to our prior, existing or future owned or leased sites or operations or those of predecessor companies whose liabilities we may have assumed or acquired.

Any significant fuel cost increases or shortages in the supply of fuel could disrupt our ability to distribute products to our customers, which could adversely affect our results of operations.

        We currently use our own fleet of over 1,500 owned and leased delivery vehicles to service customers in the regions in which we operate. As a result, we are inherently dependent upon energy to operate and are impacted by changes in diesel fuel prices. The cost of fuel has reached historically high levels during portions of the last several years, is largely unpredictable and has a significant impact on our results of operations. Fuel availability, as well as pricing, is also impacted by political and economic factors. It is difficult to predict the future availability of fuel due to the following factors, among others:

•

dependency on foreign imports of crude oil and the potential for hostilities or other conflicts in oil producing areas;



•

limited refining capacity; and



•

the possibility of changes in governmental policies on fuel production, transportation and marketing.

        Significant disruptions in the supply of fuel could have a negative impact on fuel prices and thus our financial condition and results of operations.

A disruption or breach of our IT systems could adversely impact our business and operations.

        We rely on the accuracy, capacity and security of our IT systems, some of which are managed or hosted by third parties, and our ability to continually update these systems in response to the changing needs of our business. In the ordinary course of our business, we collect and store sensitive data, including our proprietary business information and that of our customers, suppliers and business partners, and personally identifiable

22

Table of Contents

information of our customers and employees, in our data centers and on our networks. The secure processing, maintenance and transmission of this information is critical to our operations. We have incurred costs and may incur significant additional costs in order to implement the security measures that we feel are appropriate to protect our IT systems. Our security measures are focused on the prevention, detection and remediation of damage from computer viruses, natural or man-made disasters, unauthorized access, cyber attacks and other similar disruptions. Despite our security measures, our IT systems and infrastructure may be vulnerable to attacks by hackers or breached due to employee error, malfeasance or other disruptions. Any attacks on our IT systems could result in our systems or data being breached or damaged by computer viruses or unauthorized physical or electronic access. Such a breach could result in not only business disruption, but also theft of our intellectual property or other competitive information or unauthorized access to controlled data and any personal information stored in our IT systems. To the extent that any data is lost or destroyed or any confidential information is inappropriately disclosed or used, it could adversely affect our competitive position or customer relationships. In addition, any such access, disclosure or other loss of information could result in legal claims or proceedings, liability under laws that protect the privacy of personal information, damage our reputation and cause a loss of confidence in our business, products and services, which could adversely affect our business, financial condition, profitability and cash flows. To date, we have not experienced a material breach of our IT systems. However, during the course of preparing for our initial public offering, we identified a material weakness in our general IT computer controls. See "—Risks Relating to Ownership of Our Common Stock—In connection with our preparations for becoming a public company, we identified material weaknesses in our internal control over financial reporting. If our remediation of these material weaknesses is not effective, or if we experience additional material weaknesses in the future or otherwise fail to maintain an effective system of internal controls in the future, we may not be able to accurately or timely report our financial condition or results of operations, which may adversely affect investor confidence in us and, as a result, the value of our common stock."

Natural or man-made disruptions to our facilities may adversely affect our business and operations.

        We currently maintain a broad network of distribution facilities throughout the United States, as well as our Yard Support Center in Tucker, Georgia, which supports our branches with various back office functions. In the event any of our facilities are damaged or operations are disrupted from fire, earthquake, weather-related events, an act of terrorism or any other cause, a significant portion of our inventory could be damaged and our ability to distribute products to customers could be materially impaired. Moreover, we could incur significantly higher costs and experience longer lead times associated with distributing products to our customers during the time that it takes for us to reopen or replace a damaged facility. Disruptions to the national or local transportation infrastructure systems, including those related to a domestic terrorist attack, may also affect our ability to keep our operations and services functioning properly. If any of these events were to occur, our financial condition, operating results and cash flows could be materially adversely affected.

Anti-terrorism measures and other disruptions to the transportation network could impact our distribution system and our operations.

        Our ability to efficiently distribute 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 many parts of the transportation network in the United States. Our customers typically need quick delivery and rely on our on-time delivery capabilities. If security measures disrupt or impede the timing of our deliveries, we may fail to meet the needs of our customers, or may incur increased expenses to do so.

Risks Relating to Ownership of Our Common Stock

The market price of our common stock may be highly volatile, and you may not be able to resell your shares at or above the price you paid for them.

        The trading price of our common stock could be volatile, and you can lose all or part of your investment. The following factors, in addition to other factors described in this "Risk Factors" section and elsewhere in this Annual Report on Form 10-K, may have a significant impact on the market price of our common stock:

•

announcements of innovations or new products or services by us or our competitors;



•

any adverse changes to our relationship with our customers, manufacturers or suppliers;



•

variations in the costs of products that we distribute;



•

any legal actions in which we may become involved;



•

announcements concerning our competitors or the building supply industry in general;



•

achievement of expected product sales and profitability;



•

manufacture, supply or distribution shortages;



•

adverse actions taken by regulatory agencies with respect to our services or the products we distribute;



•

actual or anticipated fluctuations in our quarterly or annual operating results;



•

changes in financial estimates or recommendations by securities analysts;



•

trading volume of our common stock;



•

sales of our common stock by us, our executive officers and directors or our stockholders (including certain affiliates of AEA) in the future;



•

general economic and market conditions and overall fluctuations in the U.S. equity markets;



•

changes in accounting principles; and



•

the loss of any of our management or key personnel.

        In addition, broad market and industry factors may negatively affect the market price of our common stock, regardless of our actual operating performance, and factors beyond our control may cause our stock price to decline rapidly and unexpectedly.

We may be subject to securities litigation, which is expensive and could divert management attention.

        Our share price may be volatile and, in the past, companies that have experienced volatility in the market price of their stock have been subject to securities class action litigation. We may be the target of this type of litigation in the future. Litigation of this type could result in substantial costs and diversion of management's attention and resources, which could adversely impact our business. Any adverse determination in litigation could also subject us to significant liabilities.

Because AEA controls a significant percentage of our common stock, it may control all major corporate decisions and its interests may conflict with the interests of other holders of our common stock.

        Certain affiliates of AEA beneficially own approximately 43.4% of the voting power of our outstanding common stock. Through this beneficial ownership and a stockholders agreement, which provides voting control over additional shares of our common stock, AEA controls approximately 80.3% of the voting power of our outstanding common stock. As a result of this control, AEA is able to influence or control matters requiring approval by our stockholders and/or our board of directors, including the election of directors and the approval of business combinations or dispositions and other extraordinary transactions. AEA may also have interests that

24

---

Table of Contents

differ from yours and may vote in a way with which you disagree and which may be adverse to your interests. The concentration of ownership may have the effect of delaying, preventing or deterring a change of control of our Company, could deprive our stockholders of an opportunity to receive a premium for their common stock as part of a sale of our Company and may materially and adversely affect the market price of our common stock. In addition, AEA may in the future own businesses that directly compete with ours. See Item 13, "Certain Relationships and Related Party Transactions and Director Independence."

Sales of a substantial number of shares of our common stock in the public market by our existing stockholders could cause our stock price to fall.

        Sales of a substantial number of shares of our common stock in the public market or the perception that these sales might occur, could depress the market price of our common stock and could impair our ability to raise capital through the sale of additional equity securities. Substantially all of our stockholders prior to our initial public offering are subject to lock-up agreements with the underwriters of our initial public offering that restrict the stockholders' ability to transfer shares of our common stock for 180 days from the date of our initial public offering, or until November 21, 2016, subject to certain exceptions. The lock-up agreements limit the number of shares of common stock that may be sold immediately following our initial public offering. As of June 30, 2016, we had 40,942,905 outstanding shares of common stock. Subject to limitations, approximately 32,828,249 shares will become eligible for sale upon expiration of the lock-up period. In addition, shares issued or issuable upon exercise of options vested as of the expiration of the lock-up period will be eligible for sale at that time. Sales of stock by these stockholders could have a material adverse effect on the trading price of our common stock.

        Moreover, holders of an aggregate of 32,892,905 shares of our common stock have rights, subject to certain conditions such as the 180-day lock-up arrangement described above, to require us to file registration statements covering their shares or to include their shares in registration statements that we may file for ourselves or other stockholders. Registration of these shares under the Securities Act would result in the shares becoming freely tradable without restriction under the Securities Act, except for shares held by our affiliates as defined in Rule 144 under the Securities Act. Any sales of securities by these stockholders could have a material adverse effect on the trading price of our common stock.

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

        The trading market for our common stock will be influenced by the research and reports that industry or securities analysts may publish about us, our business, our markets or our competitors. We do not have any control over these analysts and we cannot provide any assurance that analysts will cover us or provide favorable coverage. If any of the analysts who may cover us adversely change their recommendation regarding our stock, or provide more favorable relative recommendations about our competitors, our stock price could decline. If any analyst who may cover us were to cease coverage of our 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.

Because we do not intend to declare cash dividends on our shares of common stock in the foreseeable future, stockholders must rely on appreciation of the value of our common stock for any return on their investment.

        We currently anticipate that we will retain future earnings for the development, operation and expansion of our business and do not anticipate declaring or paying any cash dividends in the foreseeable future. In addition, the terms of the ABL Facility, the First Lien Facility and any future debt agreements may preclude our subsidiaries from paying dividends to us which, in turn, may preclude us from paying dividends to our stockholders. As a result, we expect that only appreciation of the price of our common stock, if any, will provide a return to investors in our common stock for the foreseeable future.

The requirements of being a public company, including compliance with the reporting requirements of the Exchange Act and the requirements of the Sarbanes-Oxley Act and the New York Stock Exchange, may strain our resources, increase our costs and distract management, and we may be unable to comply with these requirements in a timely or cost-effective manner.

        As a public company, we are subject to the reporting requirements of the Exchange Act and the corporate governance standards of the Sarbanes-Oxley Act of 2002, or the Sarbanes-Oxley Act, and the New York Stock Exchange. As a result, we will incur significant legal, accounting and other costs that we did not incur as a private company. These requirements will place a strain on our management, systems and resources and we will incur significant legal, accounting, insurance and other expenses that we have not incurred as a private company. The Exchange Act requires us to file annual, quarterly and current reports with respect to our business and financial condition within specified time periods and to prepare a proxy statement with respect to our annual meeting of shareholders. The Sarbanes-Oxley Act requires that we maintain effective disclosure controls and procedures and internal controls over financial reporting. The New York Stock Exchange requires that we comply with various corporate governance requirements. To maintain and improve the effectiveness of our disclosure controls and procedures and internal controls over financial reporting and comply with the Exchange Act and the New York Stock Exchange requirements, significant resources and management oversight will be required. This may divert management's attention from other business concerns and lead to significant costs associated with compliance, which could have a material adverse effect on us and the price of our common stock.

        We also expect that it could be difficult and will be significantly more expensive to obtain directors' and officers' liability insurance, and we may be required to accept reduced policy limits and coverage or incur substantially higher costs to obtain the same or similar coverage. As a result, it may be more difficult for us to attract and retain qualified persons to serve on our board of directors or as executive officers. Advocacy efforts by shareholders and third parties may also prompt even more changes in governance and reporting requirements. We cannot predict or estimate the amount of additional costs we may incur or the timing of these costs.

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

        We are not currently required to comply with the SEC's rules implementing Section 404 of the Sarbanes-Oxley Act and therefore are not required to make a formal assessment of the effectiveness of our internal control over financial reporting for that purpose. As a public company, we will be required to comply with the SEC's rules implementing Section 302 and 404 of the Sarbanes-Oxley Act, which will require management to certify financial and other information in our quarterly and annual reports and provide an annual management report on the effectiveness of control over financial reporting, as well as a statement that our independent registered public accounting firm has issued an opinion on our internal control over financial reporting. Though we will be required to disclose changes made in our internal controls and procedures on a quarterly basis, we will not be required to make our first annual assessment of our internal control over financial reporting pursuant to Section 404 of the Sarbanes-Oxley Act (including an auditor attestation on management's internal controls report) until our second annual report on Form 10-K is filed with the SEC.

        During the course of preparing for our initial public offering, we identified material weaknesses in the design and operation of our internal control over financial reporting. A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of a company's annual or interim financial statements will not be prevented or detected on a timely basis. The material weaknesses included an insufficient complement of personnel with a level of U.S. GAAP accounting knowledge commensurate with our financial reporting requirements, a lack of formal accounting policies and procedures, ineffective IT general computer controls and a lack of controls over the preparation and review of manual journal entries. These deficiencies previously resulted in material adjustments to

26

---

Table of Contents

correct the previously issued consolidated financial statements of our wholly owned subsidiary, GYP Holdings III Corp. These deficiencies could result in material misstatements to our consolidated financial statements that would not be prevented or detected.

        We are currently in the process of remediating the above material weaknesses and have taken numerous steps to enhance our internal control environment and address the underlying causes of the material weaknesses. We have hired additional financial reporting personnel with technical accounting and financial reporting experience, formalized our accounting policies and procedures, and enhanced our internal review procedures during the financial statement close process. In addition, our remediation activities focused on designing and implementing the appropriate IT general computer controls are in process. Our current efforts to design and implement an effective control environment may not be sufficient to remediate the material weaknesses described above or prevent future material weaknesses or control deficiencies from occurring. There is no assurance that we will not identify additional material weaknesses in our internal control over financial reporting in the future.

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

We are a "controlled company" within the meaning of the rules of the New York Stock Exchange and, as a result, qualify for, and rely on, exemptions from certain corporate governance requirements.

        A control group, consisting of certain affiliates of AEA and certain of our other stockholders, controls a majority of the voting power of our outstanding common stock. As a result, we are a "controlled company" within the meaning of the corporate governance standards of the New York Stock Exchange. A company of which more than 50% of the voting power is held by an individual, a group or another company is a "controlled company" within the meaning of the rules of the New York Stock Exchange and may elect not to comply with certain corporate governance requirements of the New York Stock Exchange, including:

•

the requirement that a majority of our board consist of independent directors;



•

the requirement that we have a nominating/corporate governance committee that is composed entirely of independent directors with a written charter addressing the committee's purpose and responsibilities;



•

the requirement that we have a compensation committee that is composed entirely of independent directors with a written charter addressing the committee's purpose and responsibilities; and



•

the requirement for an annual performance evaluation of the nominating and corporate governance and compensation committees.

        We intend to continue to rely on all of the exemptions listed above. If we continue to utilize the exemptions, we will not have a majority of independent directors and our nominating and corporate governance and compensation committees will not consist entirely of independent directors. As a result, our board of directors and those committees may have more directors who do not meet the New York Stock Exchange's independence standards than they would if those standards were to apply. These independence standards are intended to ensure that directors who meet those standards are free of any conflicting interest that could influence their actions as directors. Accordingly, you may not have the same protections afforded to stockholders of companies that are subject to all of the corporate governance requirements of the New York Stock Exchange.

Some provisions of our charter documents and Delaware law may have anti-takeover effects that could discourage an acquisition of us by others, even if an acquisition would be beneficial to our stockholders, and may prevent attempts by our stockholders to replace or remove our current management.

        Provisions in our second amended and restated certificate of incorporation and our amended and restated bylaws, as well as provisions of the Delaware General Corporation Law, or DGCL, could make it more difficult for a third party to acquire us or increase the cost of acquiring us, even if doing so would benefit our stockholders, including transactions in which stockholders might otherwise receive a premium for their shares. These provisions include:

•

establishing a classified board of directors such that not all members of the board are elected at one time;



•

allowing the total number of directors to be determined exclusively (subject to the rights of holders of any series of preferred stock to elect additional directors) by resolution of our board of directors and granting to our board the sole power (subject to the rights of holders of any series of preferred stock or rights granted pursuant to the stockholders' agreement) to fill any vacancy on the board;



•

limiting the ability of stockholders to remove directors without cause if AEA, together with certain of our other stockholders, ceases to own 50% or more of the voting power of our common stock;



•

authorizing the issuance of "blank check" preferred stock by our board of directors, without further shareholder approval, to thwart a takeover attempt;



•

prohibiting stockholder action by written consent (and, thus, requiring that all stockholder actions be taken at a meeting of our stockholders) if AEA, together with certain of our other stockholders, ceases to own 50% or more of the voting power of our common stock;



•

eliminating the ability of stockholders to call a special meeting of stockholders, except for AEA, so long as AEA, together with certain of our other stockholders, owns 50% or more of the voting power of our common stock;



•

establishing advance notice requirements for nominations for election to the board of directors or for proposing matters that can be acted upon at annual stockholder meetings; and



•

requiring the approval of the holders of at least two-thirds of the voting power of all outstanding stock entitled to vote thereon, voting together as a single class, to amend or repeal our amended and restated certificate of incorporation or bylaws if AEA, together with certain of our other stockholders, ceases to own 50% or more of the voting power of our common stock.

        In addition, while we have opted out of Section 203 of the DGCL, our second amended and restated certificate of incorporation contains similar provisions providing that we may not engage in certain "business combinations" with any "interested stockholder" for a three-year period following the time that the stockholder became an interested stockholder, unless:

•

prior to such time, our board of directors approved either the business combination or the transaction that resulted in the stockholder becoming an interested stockholder;



•

upon consummation of the transaction that resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of our voting stock outstanding at the time the transaction commenced, excluding certain shares; or



•

at or subsequent to that time, the business combination is approved by our board of directors and by the affirmative vote of holders of at least two-thirds of our outstanding voting stock that is not owned by the interested stockholder.

        Generally, a "business combination" includes a merger, asset or stock sale or other transaction provided for or through our Company resulting in a financial benefit to the interested stockholder. Subject to certain exceptions, an "interested stockholder" is a person who owns 15% or more of our outstanding voting stock and

Table of Contents

the affiliates and associates of such person. For purposes of this provision, "voting stock" means any class or series of stock entitled to vote generally in the election of directors.

        Under certain circumstances, this provision will make it more difficult for a person who would be an "interested stockholder" to effect certain business combinations with our Company for a three year period. This provision may encourage companies interested in acquiring us to negotiate in advance with our board of directors in order to avoid the stockholder approval requirement if our board of directors approves either the business combination or the transaction that results in the stockholder becoming an interested stockholder. These provisions also may have the effect of preventing changes in our board of directors and may make it more difficult to accomplish transactions that stockholders may otherwise deem to be in their best interests.

        These anti-takeover defenses could discourage, delay or prevent a transaction involving a change in control of our Company. These provisions could also discourage proxy contests and make it more difficult for you and other stockholders to elect directors of your choosing and cause us to take corporate actions other than those you desire.

Our second amended and restated certificate of incorporation designates the Court of Chancery of the State of Delaware as the exclusive forum for certain litigation that may be initiated by our stockholders, which could limit our stockholders' ability to obtain a favorable judicial forum for disputes with us.

        Our second amended and restated certificate of incorporation provides that the Court of Chancery of the State of Delaware will be the sole and exclusive forum for (i) any derivative action or proceeding brought on our behalf, (ii) any action asserting a claim of breach of a fiduciary duty owed to us or our stockholders by any of our directors, officers, employees or agents, (iii) any action asserting a claim against us arising under the DGCL or (iv) any action asserting a claim against us that is governed by the internal affairs doctrine. By becoming a stockholder in our Company, you will be deemed to have notice of and have consented to the provisions of our second amended and restated certificate of incorporation related to choice of forum. The choice of forum provision in our second amended and restated certificate of incorporation may limit our stockholders' ability to obtain a favorable judicial forum for disputes with us.

Item 2.    Properties

Facilities

        Our corporate headquarters is in Tucker, Georgia. In addition, we have one leased sales office in Atlanta, Georgia and one owned office in Riverview, Florida. In addition, we are holding four of our owned properties for sale, with three in the Atlanta, Georgia metropolitan area and one in Winston-Salem, North Carolina. We operate our business through over 185 branches, across 41 states and the District of Columbia. The covered square footage of our warehouses is equal to an aggregate of approximately 6.1 million square feet. As of April 30, 2016, we owned 78 of our facilities, some of which were used as collateral to secure the First Lien Facility. We believe that substantially all of our property and equipment is in good condition, subject to normal wear and tear.

        As of April 30, 2016, we operated 186 branches, a few with multiple facilities, located in the following locations:

Item 3.    Legal Proceedings

        From time to time, we are involved in lawsuits that are brought against us in the normal course of business. We are not currently a party to any legal proceedings that would be expected, either individually or in the aggregate, to have a material adverse effect on our business or financial condition.

        The building materials industry has been subject to personal injury and property damage claims arising from alleged exposure to raw materials contained in building products as well as claims for incidents of catastrophic loss, such as building fires. As a distributor of building materials, we face an inherent risk of exposure to product liability claims in the event that the use of the products we have distributed in the past or may in the future distribute is alleged to have resulted in economic loss, personal injury or property damage or violated environmental, health or safety or other laws. Such product liability claims have included and may in the future include allegations of defects in manufacturing, defects in design, a failure to warn of dangers inherent in the

Table of Contents

product, negligence, strict liability or a breach of warranties. In particular, certain of our subsidiaries have been the subject of claims related to alleged exposure to asbestos-containing products they distributed prior to 1979, which have not materially impacted our financial condition or operating results. Since 2002, approximately 944 asbestos-related personal injury lawsuits have been brought and we vigorously defend against them. Of these, 855 have been dismissed without any payment by us, 21 are on deferred or inactive court dockets, 63 are pending and only 5 have been settled. In total, we have paid an aggregate of less than $300,000 in connection with these settlements. One of the pending cases is currently scheduled for trial later this year and is in the early stages of discovery. The complaint names one of our subsidiaries, along with multiple other parties, as a defendant and seeks unspecified damages. Despite our past experience, the amount, if any, required to resolve this matter may be significantly higher than amounts paid in prior settlements and could be material to us. We have not recorded a reserve, nor disclosed a potential range, for this matter because the amount of any exposure cannot be reasonably estimated at this time. See Item 1A, "Risk Factors—Risks Relating to Our Business and Industry—We are exposed to product liability, warranty, casualty, construction defect, contract, tort, employment and other claims and legal proceedings related to our business, the products we distribute, the services we provide and services provided for us by third parties."

PART II

Item 5.    Market for Registrant's Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities

        The Company's common stock began trading on the NYSE under the symbol "GMS" on May 26, 2016. Before then, there was no public market for the Company's common stock.

        We used the net proceeds from our IPO together with cash on hand to repay $160.0 million principal amount of our term loan debt outstanding under the Second Lien Facility, which was a payment in full of the entire loan balance due under the Second Lien Facility.

        As of the close of business on June 30, 2016, there were 93 holders of record of the Company's common stock, which does not reflect those shares held beneficially or those shares held in "street" name. Accordingly, the number of beneficial owners of our common stock exceeds this number.

Dividend Policy

        No dividends were paid to stockholders during fiscal 2016 or fiscal 2015. The Company currently intends to retain all of its future earnings, if any, to finance operations, development and growth of its business and repay indebtedness. Most of the Company's indebtedness contains restrictions on the Company's activities, including paying dividends on its capital stock. See Note 8, "Long-Term Debt" of Part II, Item 8 of this Annual Report on Form 10-K. Any future determination relating to our dividend policy will be made at the discretion of the Company's board of directors and will depend on a number of factors, including future earnings, capital requirements, financial conditions, future prospects, contractual restrictions and covenants and other factors that the board of directors may deem relevant.

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

Recent Events

        On June 1, 2016, we completed our initial public offering, or IPO, of 8,050,000 shares of common stock at a price of $21.00 per share, including 1,050,000 shares of common stock that were issued as a result of the exercise in full by the underwriters an option to purchase additional shares to cover over-allotments. After underwriting discounts and commissions but before expenses, we received net proceeds from the initial public offering (the "IPO") of approximately $157.2 million. We used these proceeds together with cash on hand to repay $160.0 million principal amount of our term loan debt outstanding under our senior secured second lien term loan facility, or the Second Lien Facility, which was a payment in full of the entire loan balance due under the Second Lien Facility.

        On May 13, 2016, we amended and restated our certificate of incorporation to increase our authorized share count to 550,000,000 shares of stock, including 500,000,000 shares of common stock and 50,000,000 shares of preferred stock, each with a par value $0.01 per share and to split our common stock 10.158-for-1. Unless otherwise noted herein, historic share data has been adjusted to give effect to the stock split.

        Subsequent to April 30, 2016, we acquired Wall & Ceiling Supply Co., Inc. (Wall & Ceiling Supply) and Rockwise, LLC (Rockwise) for a total purchase price of approximately $26.3 million. Wall & Ceiling Supply and Rockwise distribute wallboard and related building materials from four locations in Washington, Arizona and Colorado. For the twelve months ended April 30, 2016, the combined companies generated approximately $35.2 million in net sales and the earnings of these entities would have contributed approximately $4.5 million to our Adjusted EBITDA for that period, including operating synergies.

Effect of the Acquisition

        On April 1, 2014, GMS Inc., or the Successor, acquired, through its wholly-owned entities, GYP Holdings II Corp. and GYP Holdings III Corp., all of the capital stock of Gypsum Management and Supply, Inc., or the Predecessor. Successor is majority owned by certain affiliates of AEA and certain of our other stockholders. We refer to this acquisition as the "Acquisition."

        As a result of the Acquisition, the financial information for the periods beginning on April 1, 2014, and through and including April 30, 2016, represents the consolidated financial statements of the Successor. The financial information for the period prior to, and including, March 31, 2014, represents the consolidated financial statements of the Predecessor. Due to the change in the basis of accounting resulting from the application of the acquisition method of accounting, the Predecessor's consolidated financial statements and the Successor's consolidated financial statements are not necessarily comparable. The new basis of accounting primarily impacted the values of our inventory, long-lived and indefinite-lived intangible assets, and resulted in increased depreciation and amortization expenses. The impact of the Acquisition also resulted in increased interest expense and increases in selling, general and administrative expenses. However, the change in basis resulting from the Acquisition did not impact net sales or Adjusted EBITDA and, for these metrics, we believe combining Predecessor and Successor results provides meaningful information. Accordingly, certain discussions below for net sales and Adjusted EBITDA present the combined results of the Predecessor and the Successor for the full year ended April 30, 2014. Such combination was performed by mathematical addition and is not a presentation made in accordance with GAAP, although we believe it provides a meaningful method of comparison for these two metrics. The combined net sales and Adjusted EBITDA data is being presented for informational purposes only. The combined operating results for these two metrics for the full year ended April 30, 2014 (i) have not been prepared on a pro forma basis as if the Acquisition occurred on the first day of the period, (ii) may not reflect the actual results we would have achieved absent the Acquisition, (iii) may not be predictive of our future results of operations and (iv) should not be viewed as a substitute for the financial results of the Predecessor and the Successor presented in accordance with GAAP. For all other metrics, to the extent that the change in basis had a material impact on our results, we have disclosed such impact under "—Results of Operations."

Business Overview

        Founded in 1971, we are the leading North American distributor of wallboard and ceilings. Our core customer is the interior contractor, who typically installs wallboard, ceilings and our other interior construction products in commercial and residential buildings. As a leading specialty distributor, we serve as a critical link between our suppliers and a highly fragmented customer base of over 20,000 contractors. Our operating model combines a national platform with a local go-to-market strategy through over 185 branches across the country. We believe this combination enables us to generate economies of scale while maintaining the high service levels, entrepreneurial culture and customer intimacy of a local business.

        Our growth strategy entails taking market share within our existing footprint, expanding into new markets by opening new branches and strategic acquisitions. We expect to continue to capture profitable market share in our existing footprint by delivering industry-leading customer service. Our strategy for opening new branches is to further penetrate markets that are adjacent to our existing operations. Typically, we have pre-existing customer relationships in these markets but need a new location to fully capitalize on those relationships. Since the beginning of full year 2014, we have opened 21 new branches and we currently expect to open several new branches each year depending on market conditions. In addition, we will continue to selectively pursue tuck-in

acquisitions and have a dedicated team of professionals to manage the process. Due to the large, highly fragmented nature of our market and our reputation throughout the industry, we believe we have the potential to access a robust acquisition pipeline that will continue to supplement our organic growth. We use a rigorous targeting process to identify acquisition candidates that will fit our culture and business model. As a result of our scale, purchasing power and ability to improve operations through implementing best practices, we believe we can achieve substantial synergies and drive earnings accretion from our acquisition strategy.

Factors and Trends Affecting our Operating Results

General Economic Conditions and Outlook

        Our business is sensitive to changes in general economic conditions, including, in particular, conditions in the North American commercial construction and housing markets. The markets we serve are broadly categorized as commercial new construction, commercial R&R, residential new construction and residential R&R. We believe all four end markets are currently in an extended period of expansion following a deep and prolonged downturn.

        Our addressable commercial construction market is composed of a variety of commercial and institutional sub-segments with varying demand drivers. Our commercial markets include offices, hotels, retail stores and other commercial buildings, while our institutional markets include educational facilities, healthcare facilities, government buildings and other institutional facilities. The principal demand drivers across these markets include the overall economic outlook, the general business cycle, government spending, vacancy rates, employment trends, interest rates, availability of credit and demographic trends. Given the extreme depth of the last recession, despite the growth to date, activity in the commercial construction market remains well below average historical levels. According to Dodge Data & Analytics, new commercial construction put in place was 935 million square feet during the 2015 calendar year, which is an increase of 38% from 680 million square feet during the 2010 calendar year. However, new commercial construction activity remains well below historical levels. New commercial construction square footage put in place of 935 million square feet in 2015 would have needed to increase by 36% in order to achieve the historical market average of 1.3 billion square feet annually since 1970. We believe this represents a significant growth opportunity as activity continues to improve.

        We believe commercial R&R spending is typically more stable than new commercial construction activity. Commercial R&R spending is driven by a number of factors, including commercial real estate prices and rental rates, office vacancy rates, government spending and interest rates. Commercial R&R spending is also driven by commercial lease expirations and renewals, as well as tenant turnover. Such events often result in repair, reconfiguration and/or upgrading of existing commercial space. As such, the commercial R&R market has historically been less volatile than commercial new construction. While there is very limited third party data for commercial R&R spending, we believe spending in this end market is in a period of expansion.

        Residential construction activity is driven by a number of factors, including the overall economic outlook, employment, income growth, home prices, availability of mortgage financing, interest rates and consumer confidence, among others. According to the U.S. Census Bureau, U.S. housing starts reached 1.1 million in the 2015 calendar year, which is an increase of 10% from 2014 starts of 1.0 million. While housing starts increased for the sixth consecutive year in 2015, activity in the market remains well below historical levels. New residential housing starts of 1.1 million in 2015 would have needed to increase by 30% in order to reach their historical market average of 1.5 million annually since 1970.

        While residential R&R activity is typically more stable than new construction activity, we believe the prolonged period of under-investment during the recent downturn will result in above-average growth for the next several years. The primary drivers of residential R&R spending include changes in existing home prices, existing home sales, the average age of the housing stock, consumer confidence and interest rates. According to the U.S. Census Bureau, residential R&R spending, including repairs and improvements, reached $285.4 billion in the 2015 calendar year, which is an increase of 4.4% from $273.3 billion in 2014.

Seasonality and Inflation

        Our operating results are typically impacted by seasonality. Historically, sales of our products have been slightly higher in the first and second quarters of each fiscal year (covering the calendar months of May through October) due to favorable weather and longer daylight conditions during these periods. Seasonal variations in operating results may be impacted by inclement weather conditions, such as cold or wet weather, which can delay construction projects.

        We believe that our results of operations are not materially impacted by moderate changes in the economic inflation rate. In general, we have historically been successful in passing on price increases from our vendors to our customers in a timely manner, although there is no assurance that we can successfully do so in the future.

Acquisitions

        We complement our organic growth strategy with selective, tuck-in acquisitions. Since the beginning of full year 2014 through April 30, 2016, we completed 15 strategic acquisitions, of Dakota Gypsum, Sun Valley Supply, Inc., Contractors' Choice Supply, Inc., Drywall Supply, Inc., AllSouth Drywall Supply Company, Serrano Supply, Inc., Ohio Valley Building Products, LLC, J&B Materials, Inc., Tri-Cities Drywall & Supply Co., Badgerland Supply, Inc., Hathaway & Sons, Inc., Gypsum Supply Company, Robert N. Karpp Company, Inc., Professional Handling & Distribution, Inc. and M.R. Lee Building Materials, Inc. totaling 38 branches. We believe that significant opportunities exist to expand our geographic footprint by executing additional strategic acquisitions and we consistently strive to maintain an extensive and active acquisition pipeline. We are often evaluating several acquisition opportunities at any given time.

Debt Refinancings

        Amounts outstanding under our $175.0 million revolving credit agreement with certain financial institutions, or the 2010 Credit Facility, were repaid in conjunction with the Acquisition. At such time, we entered into the ABL Facility, the First Lien Facility and the Second Lien Facility. We refer to the First Lien Facility and the Second Lien Facility, together, as the "Term Loan Facilities." As a result of the higher debt levels following these refinancings, our interest expense increased during the full year ended April 30, 2014 and the fiscal years ended April 30, 2015 and 2016. See "—Our Credit Facilities" below.

Our Products

Net Sales

        Net sales of $1,858.2 million for the fiscal year ended April 30, 2016 increased $288.1 million, or 18.3%, from $1,570.1 million for the fiscal year ended April 30, 2015. Our performance in the fiscal year ended April 30, 2016 was strong as our sales increased across all product categories. In the fiscal year ended April 30, 2016, our wallboard sales, which are impacted by both commercial and residential construction activity, increased by $152.8 million, or 21.3%, compared to the fiscal year ended April 30, 2015. The increase in wallboard sales was a result of a 22.1% increase in unit volume primarily driven by greater end market demand, market share gains and the impact of acquisitions, partially offset by a 0.7% decrease in pricing. In addition, in the fiscal year ended April 30, 2016, our ceiling sales increased $18.4 million, or 6.6%, from the fiscal year ended April 30, 2015, and steel framing sales increased $38.2 million, or 15.7%. Ceiling and steel framing sales increased primarily as a result of increases in commercial construction activity. For the fiscal year ended April 30, 2016, our other products sales category, which includes tools, insulation, joint treatment and various other products, increased $78.7 million, or 23.8%, compared to the fiscal year ended April 30, 2015.

        From February 1, 2014 through April 30, 2016, we have completed 13 acquisitions, totaling 36 branches. These acquisitions contributed $215.8 million and $44.4 million to our net sales in fiscal 2016 and fiscal 2015, respectively. Excluding these acquired sites, for fiscal 2016 and fiscal 2015, our base business net sales increased $116.7 million, or 7.6%, compared to the fiscal year ended April 30, 2015. The overall increase in our base business net sales reflected the increase in demand for our products as a result of the improvement in new housing starts, R&R activity and commercial construction, coupled with market share gains.

        In addition, our base business improved through the addition of 14 new greenfield branches opened, which contributed $57.3 million to our base business net sales in the fiscal year ended April 30, 2016 while the nine new greenfield branches opened in fiscal 2015 contributed $21.3 million to our base business net sales for the fiscal year ended April 30, 2015.

        The following table breaks out our consolidated net sales into the base business component and the excluded component, which consist of recently acquired branches, as shown below:

        When calculating our "base business" results, we exclude any branches that were acquired in the current fiscal year, prior fiscal year and three months prior to the start of the prior fiscal year. Therefore, any acquisition occurring between February 1, 2014 and April 30, 2016 will be excluded from base business net sales for any period during fiscal 2016.

Table of Contents

        We have excluded the following acquisitions from the base business for the periods identified:

Gross Profit and Gross Margin

        Gross profit was $593.2 million for the fiscal year ended April 30, 2016 compared to $479.0 million for the fiscal year ended April 30, 2015. The increase in gross profit was due to $288.1 million in additional sales, partially offset by a $173.9 million increase in cost of sales. Gross margin on net sales increased to 31.9% for the fiscal year ended April 30, 2016 from 30.5% for the fiscal year ended April 30, 2015 primarily as the result of improved product margins and mix. Our gross margin for the fiscal year ended April 30, 2015 was negatively impacted by 29 basis points due to the increase in cost of sales of $4.5 million related to a purchase accounting adjustment related to the Acquisition. This fair value adjustment increased our cost of sales as the increase in inventory value was recorded over the average inventory turnover period.

Selling, General and Administrative Expenses

        Selling, general and administrative expenses consist of warehouse, delivery and general and administrative expenses. Our selling, general and administrative expenses increased $73.9 million, or 18.6%, to $470.0 million for the fiscal year ended April 30, 2016 from $396.2 million for the fiscal year ended April 30, 2015. This increase was due to increases in warehouse expense of $10.7 million, of which $4.8 million was related to payroll; delivery expense of $30.7 million, of which $21.1 million was related to payroll and $6.2 million was related to equipment rental cost increases; and increases in branch and corporate general and administrative expenses of $32.4 million, of which $17.4 million was related to payroll, $7.5 million was related to employee benefits, $4.1 million was related to increases in real estate rental expense and $1.9 million was related to the costs of acquisitions and our initial public offering. The increases in payroll and payroll related costs were primarily due to increased headcount, which was due to the increase in delivered volume, acquisitions and the expansion of the Yard Support Center. Selling, general and administrative expenses were 25.3% and 25.2% of our net sales for the fiscal years ended April 30, 2016 and 2015, respectively.

Depreciation and Amortization Expense

        Depreciation and amortization expense was $64.2 million for each of the fiscal years ended April 30, 2016 and 2015. Depreciation expense decreased by $5.5 million, due to assets becoming fully depreciated but was fully offset by an increase in amortization of acquired definite lived intangible assets of $5.5 million. The definite lived intangible assets primarily consists of customer relationships obtained from acquisitions during fiscal 2016 and fiscal 2015.

Other Expense

        Other expense consists primarily of interest expense associated with our debt, interest income and miscellaneous non-operating income.

        Interest expense increased by $1.0 million to $37.4 million in the fiscal year ended April 30, 2016 from $36.4 million for the fiscal year ended April 30, 2015. The Term Loan Facilities had a balance of $542.2 million and $546.1 million as of April 30, 2016 and 2015, respectively. See "—Our Credit Facilities." Interest expense of $31.3 million and $31.3 million related to the Term Loan Facilities was recognized for fiscal 2016 and fiscal 2015, respectively. Cash paid for interest on the First Lien Facility was $18.5 million and $18.7 million in the fiscal years ended April 30, 2016 and 2015, respectively. Cash paid for interest on the Second Lien Facility was $13.6 million and $11.5 million in the fiscal years ended April 30, 2016 and 2015, respectively. As discussed in "—Recent Events" we fully repaid the Second Lien Facility using net proceeds from our IPO. The ABL Facility, which was entered into in connection with the Acquisition, had a $101.9 million and $17.0 million outstanding balance as of April 30, 2016 and 2015, respectively, and interest expense of $2.0 million and $1.2 million for fiscal 2016 and fiscal 2015, respectively. Other interest expense incurred in fiscal 2016 and fiscal 2015 was $4.1 million and $3.9 million, respectively, primarily consisting of interest expense related to capitalized leases and deferred financing costs and discounts amortized to interest expense.

Income Tax Expense (Benefit)

        Income tax expense was $12.6 million for the fiscal year ended April 30, 2016 compared to an income tax benefit of $6.6 million for the fiscal year ended April 30, 2015. This $19.2 million increase in income tax expense was primarily the result of an increase in taxable income due to higher profitability. Our effective tax rate was 50.0% and 36.2% for the fiscal years ended April 30, 2016 and 2015, respectively. The increase in the rate from the fiscal year ended April 30, 2015 to the fiscal year ended April 30, 2016 is due to the generation of pre-tax operating profit. The effective tax rate of 50.0% varies from the federal and state blended statutory rate of approximately 38.1%. This variance was driven primarily by the non-deductibility of interest expense and specific intangible asset amortization in certain states, which increased the effective rate by 5.2%. The remainder of the variance was related to other permanent non-deductible items, including meals and entertainment, certain transaction costs, and liabilities to noncontrolling interest holders.

Net Income (Loss)

        Net income of $12.6 million for the fiscal year ended April 30, 2016 increased $24.3 million from our net loss of $11.7 million for the fiscal year ended April 30, 2015. The net income of $12.6 million for the fiscal year ended April 30, 2016 was comprised of operating profit of $58.9 million, interest expense of $37.4 million, other income of $3.7 million and income tax expense of $12.6 million. The net loss of $11.7 million for the fiscal year ended April 30, 2015 was comprised of operating profit of $18.7 million, interest expense of $36.4 million, decrease in the fair value of financial instruments of $2.5 million, other income of $1.9 million and income tax benefit of $6.6 million.

Adjusted EBITDA

        Adjusted EBITDA of $150.3 million for the fiscal year ended April 30, 2016 increased $36.4 million, or 32.0%, from our Adjusted EBITDA of $113.9 million for the fiscal year ended April 30, 2015. The increase in Adjusted EBITDA was primarily due to increased profitability on higher net sales during the fiscal year ended April 30, 2016, which was partially offset by increases in variable costs to support the increased sales volumes. These variable costs include warehouse and delivery costs and other variable compensation.

Net Sales

        Net sales of $1,570.1 million for the fiscal year ended April 30, 2015 increased $216.7 million, or 16.0%, from $1,353.3 million for the full year ended April 30, 2014. Our performance in fiscal 2015 was strong as our sales increased across all product categories. In fiscal 2015, our wallboard sales, which are impacted by both commercial and residential construction activity, increased by $115.3 million, or 19.1% from the full year ended April 30, 2014, primarily as a result of a 6.9% increase in product prices and an 11.5% increase in unit volume. In addition, in fiscal 2015, our ceiling sales increased $21.8 million, or 8.5%, from the full year ended April 30, 2014, and steel framing sales increased $26.6 million, or 12.3%. Ceiling and steel framing sales are primarily driven by commercial construction activity.

        During the fiscal year ended April 30, 2015, we completed six acquisitions, totaling 11 branches. During the full year ended April 30, 2014, we completed two acquisitions, totaling two branches. These acquisitions contributed $71.0 million and $14.1 million to our net sales in fiscal 2015 and the full year 2014, respectively. Excluding the sites we acquired in fiscal 2015 and full year 2014, our base business net sales increased 11.9% compared to the full year ended April 30, 2014. When calculating our "base business" results, we exclude any branches that were acquired in the current fiscal year, prior fiscal year and three months prior to the start of the prior fiscal year. The overall increase in our base business net sales for fiscal 2015 reflected the increase in demand for our products as a result of the improvement in new housing starts, R&R activity and commercial construction, coupled with market share gains attributed to continued improvements in customer service levels. In addition, our base business improved through the addition of nine new branches opened in fiscal 2015. These new branches contributed $21.3 million to our base business net sales in fiscal 2015.

        The following table breaks out our consolidated net sales into the base business component and the excluded components, which are the recently acquired branches excluded from the base business:

        We have excluded the following acquisitions from the base business for the periods identified:

Gross Profit and Gross Margin

        Gross profit was $479.0 million for the fiscal year ended April 30, 2015. Gross profit during the one month ended April 30, 2014 and the eleven months ended March 31, 2014 was $29.4 million and $373.0 million, respectively. As a result of the Acquisition, we applied the acquisition method of accounting and increased the value of our inventory by $12.8 million as of April 1, 2014. This adjustment increased our cost of sales during the fiscal year ended April 30, 2015 and the one month ended April 30, 2014 by $4.5 million and $8.3 million, respectively, as the related inventory was sold. Gross margin on net sales was 30.5% for the fiscal year ended April 30, 2015. Our gross margin on net sales during the one month ended April 30, 2014 and the eleven months ended March 31, 2014 was 23.1% and 30.4%, respectively. The purchase accounting adjustments to cost of sales negatively impacted our gross margin on net sales during the fiscal year ended April 30, 2015 and the one month ended April 30, 2014 by 29 basis points and 652 basis points, respectively. The favorable gross profit in fiscal 2015 was primarily the result of increased volumes and higher pricing, partially offset by higher cost of sales.

Selling, General and Administrative Expenses

        Selling, general and administrative expenses consist of warehouse, delivery and general and administrative expenses. Our selling, general and administrative expenses were $396.2 million for the fiscal year ended April 30, 2015. For the one month ended April 30, 2014 and the eleven months ended March 31, 2014, selling, general and administrative expenses were $46.1 million and $352.9 million, respectively. With respect to costs related to the Acquisition, $16.2 million and $51.8 million were included in selling, general and administrative expenses for the one month ended April 30, 2014 and the eleven months ended March 31, 2014, respectively. Selling, general and administrative expenses were $399.0 million for the full year 2014. Excluding costs related to the Acquisition, these expenses were $331.0 million. Excluding the Acquisition related costs, selling, general and administrative expenses increased $65.2 million, or 19.7%, to $396.2 million for the fiscal year ended April 30, 2015. This increase was due to increases in warehouse expense of $3.3 million, of which $2.0 million was related to payroll; delivery expense of $18.9 million, of which $11.8 million was related to payroll; and increases in branch and corporate general and administrative expenses of $43.0 million, of which $24.1 million was related to payroll. The increases in payroll and payroll related costs were primarily due to increased headcount, which was due to the increase in delivered volume, acquisitions and the expansion of the yard support center. Selling, general and administrative expenses were 25.2%, 36.2% and 28.8% of our net sales during the fiscal year ended April 30, 2015, the one month ended April 30, 2014 and the eleven months ended March 31, 2014, respectively. Costs related to the Acquisition increased the percentage for the one month ended April 30, 2014 and the eleven months ended March 31, 2014 by 1,272 basis points and 423 basis points, respectively.

Depreciation and Amortization Expenses

        Depreciation and amortization expenses were $64.2 million for the fiscal year ended April 30, 2015. For the one month ended April 30, 2014 and the eleven months ended March 31, 2014, depreciation and amortization expenses were $6.3 million and $12.3 million, respectively. As a result of the application of purchase accounting, at

47

Table of Contents

April 1, 2014, we increased the values of certain long-lived assets, including property and equipment. The impact of such adjustments increased depreciation expenses during the fiscal year ended April 30, 2015 and the one month ended April 30, 2014 by $16.4 million and $2.6 million, respectively. Amortization of definite-lived intangibles for the fiscal year ended April 30, 2015 was $32.0 million and was comprised of amortization on intangible assets acquired in the AEA Transaction. Amortization expenses for the one month ended April 30, 2014 was $2.5 million, representing one month of expense for the acquired intangibles.

Other Expense

        Other expense primarily consists of interest expense associated with our debt, interest income, miscellaneous non-operating income and the change in fair value associated with the mandatorily redeemable common shares of Predecessor.

        Interest expense was $36.4 million in the fiscal year ended April 30, 2015. For the one month ended April 30, 2014 and the eleven months ended March 31, 2014, interest expense was $3.0 million and $4.2 million, respectively. Our interest expense increased, subsequent to the Acquisition closing date, as a result of the incurrence of the term loan debt in connection with the Acquisition. Amounts outstanding under our $175.0 million 2010 Credit Facility were fully repaid with the proceeds of the Term Loan Facilities. See "—Our Credit Facilities." The Term Loan Facilities had a balance of $546.1 million and $550.0 million as of April 30, 2015 and 2014, respectively. Interest expense of $31.3 million and $2.6 million related to the Term Loan Facilities was recognized for the fiscal year ended April 30, 2015 and the one month ended April 30, 2014, respectively. The ABL Facility, which was entered into in connection with the Acquisition, had a balance of $17.0 million as of April 30, 2015 and interest expense of $1.2 million for the fiscal year ended April 30, 2015. Other interest expense incurred in the fiscal year ended April 30, 2015 was $3.9 million, primarily related to deferred financing costs and discounts amortized to interest expense.

        Because Predecessor common stock included features that required Predecessor to redeem such shares upon the death or termination of employment with Predecessor by the shareholder, we reflected the change in such fair value as a non-operating charge in our consolidated statements of operations for the eleven months ended March 31, 2014. This non-cash charge was $200.0 million for the eleven months ended March 31, 2014. The change in the fair value of mandatorily redeemable common shares was attributable to appreciation of the value of the common shares. On April 1, 2014, all outstanding shares were acquired in the Acquisition. See Note 9, "Predecessor Mandatorily Redeemable Common Shares" of Part II, Item 8 of this Annual Report on Form 10-K.

Income Tax (Benefit) Expense

        Income tax benefit was $6.6 million for the fiscal year ended April 30, 2015. For the one month ended April 30, 2014, we recorded an income tax benefit of $6.9 million. For the eleven months ended March 31, 2014, we recorded an income tax expense of $6.6 million. We recorded valuation allowances of $0.1 million, $1.3 million and $1.4 million in the fiscal year ended April 30, 2015, the one month ended April 30, 2014 and the eleven months ended March 31, 2014, respectively. Our effective tax rate was 36.2%, 26.6% and 3.4% for the fiscal year ended April 30, 2015, the one month ended April 30, 2014 and the eleven months ended March 31, 2014, respectively. Tax (benefit) expense for the one month ended April 30, 2014 and the eleven months ended March 31, 2014 differs from the statutory rate due to non-deductible charges related to non-deductible Acquisition-related transaction costs, state taxes and other permanent items. For the eleven months ended March 31, 2014, the primary drivers of the effective rate of 3.4% (or tax expense of $6.6 million) were $70.0 million of change in fair value of mandatorily redeemable common shares, $1.4 million in state income taxes, $2.2 million in non-deductible Acquisition-related transaction costs and $0.1 million of other permanent differences offset by $68.0 million of tax at the statutory rate.

Net Loss

        Net loss was $11.7 million, $19.0 million and $200.9 million, for the fiscal year ended April 30, 2015, the one month ended April 30, 2014 and the eleven months ended March 31, 2014, respectively. The net loss of

Table of Contents

$11.7 million for the fiscal year ended April 30, 2015 was comprised of operating profit of $18.7 million, interest expense of $36.4 million, decrease in the fair value of financial instruments of $2.5 million, other income of $1.9 million and income tax benefit of $6.6 million. The net loss of $19.0 million for the one month ended April 30, 2014 was comprised of operating loss of $23.0 million, interest expense of $3.0 million, other income of $0.2 million and income tax benefit of $6.9 million. The net loss of $200.9 million for the eleven months ended March 31, 2014 was comprised of operating income of $7.8 million, interest expense of $4.2 million, increase in the fair value of mandatorily redeemable common shares of $200.0 million, other income of $2.2 million and income tax expense of $6.6 million.

Adjusted EBITDA

        Adjusted EBITDA of $113.9 million for the fiscal year ended April 30, 2015 increased $26.8 million, or 30.8%, from our Adjusted EBITDA of $87.1 million for the full year ended April 30, 2014. Excluding $8.1 million in contributions from acquisitions for the pre-acquisition period, Adjusted EBITDA margin increased approximately 31 basis points to 6.7% in the fiscal year ended April 30, 2015, compared to 6.4% in the full year ended April 30, 2014. The increase in Adjusted EBITDA was primarily due to increased profitability on higher net sales during the fiscal year ended April 30, 2015, which was partially offset by increases in variable costs to support the increased sales volumes. These variable costs include warehouse and delivery costs and other variable compensation. Additionally, expenses at our Yard Support Center increased approximately $4.5 million in fiscal 2015, primarily due to higher payroll and payroll related costs associated with an increase in corporate headcount and higher incentive compensation expense associated with our strong financial performance. See "—Non-GAAP Financial Measures" for more information and for a reconciliation of Adjusted EBITDA to net income (loss), the most directly comparable financial measure calculated in accordance with GAAP.

Liquidity and Capital Resources

Summary

        We depend on cash flow from operations, cash on hand and funds available under the ABL Facility to finance working capital needs and capital expenditures. We believe that these sources of funds will be adequate to fund debt service requirements and provide cash, as required, to support our strategies, ongoing operations, capital expenditures, lease obligations and working capital for at least the next 12 months.

        In February 2016, we amended our ABL Facility to exercise the $100.0 million accordion feature of the ABL Facility which increased the aggregate revolving commitments from $200.0 million to $300.0 million and increased the sublimit for same day swing line borrowings from $20.0 million to $30.0 million. The other terms of the ABL Facility remain unchanged.

        As of April 30, 2016, we had available borrowing capacity of approximately $187.2 million under our $300.0 million ABL Facility, after giving effect to the amendment to the ABL Facility. For a summary of selected terms of the ABL Facility and other indebtedness, see "—Our Credit Facilities."

        During the fiscal years ended April 30, 2016 and 2015, our use of cash was primarily driven by our investing activities, particularly our investments in acquisitions and property and equipment for our operating facilities.

        As discussed in "—Recent Events" we repaid the Second Lien Term Loan using proceeds from our Initial Public Offering.

Treasury Stock

        In the fiscal year ended April 30, 2016, we repurchased 394,577 shares of our common stock at a cost of $5.8 million in connection with our separation agreement with a former employee. We then reissued these shares for proceeds of $4.9 million. The difference between the cost of the treasury stock and the proceeds from its reissuance was accounted for, using the "cost" method, as an increase to accumulated deficit of $1.0 million. We do not have plans to repurchase a significant number of shares in the near future.

Cash Flows

        A summary of our operating, investing and financing activities is shown in the following table:

Operating Activities

        Cash from operating activities consists primarily of net income adjusted for non-cash items, including depreciation and amortization, equity-based compensation, deferred taxes and the effects of changes in operating assets and liabilities, which were primarily the changes in working capital discussed above.

        Net cash provided by operating activities was $47.7 million for the fiscal year ended April 30, 2016. This cash provided by operating activities was the result of net income of $12.6 million, non-cash adjustments of $70.8 million, including depreciation and amortization of $67.7 million, and changes in current assets and liabilities of $11.8 million, partially offset by cash used for primary working capital of $27.0 million, primarily driven by an increase in trade accounts and notes receivable, and deferred tax benefits of $20.5 million.

        Net cash provided by operating activities was $48.0 million for the fiscal year ended April 30, 2015. This primarily consisted of non-cash charges of $81.0 million, including depreciation and amortization of $67.5 million, combined with changes in current assets and liabilities of $20.3 million, partially offset by a net loss of $11.7 million, deferred tax benefits of $21.7 million and changes in primary working capital of $19.9 million, which was necessary to support the sales increases in the fiscal year ended April 30, 2015 as well as the addition of acquired businesses and new branches.

        Net cash used in operating activities was $14.9 million in the one month ended April 30, 2014, which primarily consisted of a net loss of $19.0 million and deferred tax benefits of $6.9 million, partially offset by non-cash charges of $7.8 million, including depreciation and amortization of $6.6 million, combined with changes in current assets and liabilities of $3.2 million. In the eleven months ended March 31, 2014, cash provided by operating activities of $36.1 million was primarily driven by non-cash charges of $214.7 million, including the change in fair value of mandatorily redeemable common shares of $200.0 million and depreciation and amortization of $12.8 million, combined with changes in current assets and liabilities of $57.0 million including approximately $48.9 million in costs associated with the Acquisition, partially offset by a net loss of $200.9 million, deferred tax benefits of $7.1 million and changes in primary working capital of $27.6 million.

Investing Activities

        Net cash used in investing activities consists primarily of cash used for acquisitions; investments in our facilities including purchases of land, buildings, and leasehold improvements; and purchases of fleet assets, IT, and other equipment. We present this figure net of proceeds from asset sales which typically relate to sales of our fleet assets and assets held for sale.

Table of Contents

        In the fiscal year ended April 30, 2016, net cash used in investing activities was $111.4 million, net of $9.8 million in proceeds from asset sales. This amount consisted of $113.6 million used to acquire seven businesses, $2.5 million of facilities expenditures consisting of building and leasehold improvements, and $5.1 million of other capital expenditures in fiscal 2016.

        In the fiscal year ended April 30, 2015, net cash used in investing activities was $81.5 million, net of $3.8 million in proceeds from asset sales. This amount consisted of $66.7 million used to acquire six businesses, $4.6 million used to acquire an interest rate cap (see Note 1, "Basis of Presentation, Business and Summary of Significant Accounting Policies" of Part II, Item 8 of this Annual Report on Form 10-K), $10.1 million of facilities expenditures and $3.8 million of other capital expenditures. Our facilities expenditures included investments made to purchase land and warehouses for the purpose of relocating and optimizing branches in Atlanta, Georgia and Milton, Florida and leasehold improvements associated with the relocation of our corporate headquarters.

        During the one month ended April 30, 2014, net cash used in investing activities was $703.3 million. Of this amount, $703.0 million was used in the Acquisition.

        During the eleven months ended March 31, 2014, net cash used in investing activities was $8.4 million, net of $4.4 million in proceeds from asset sales. This amount consisted of $5.0 million used to acquire two businesses, $3.8 million in facilities expenditures and $3.9 million of other capital expenditures. Our facilities expenditures included investments made to purchase land and warehouses for the purpose of relocating and optimizing branches in Winston-Salem, North Carolina and Duluth, Georgia.

        Capital expenditures vary depending on prevailing business factors, including current and anticipated market conditions. Historically, capital expenditures have for the most part remained at relatively low levels in comparison to the operating cash flows generated during the corresponding periods. We expect our fiscal 2017 capital expenditures to be approximately $8.0 million to $10.0 million (excluding acquisitions) primarily related to fleet and equipment purchases, facilities and IT investments to support our operations.

Financing Activities

        Cash provided by, or used in, financing activities consists primarily of borrowings and related repayments under our credit agreements, as well as repayments of capital lease obligations and proceeds from the sales of equity.

        Net cash provided by financing activities was $70.5 million for the fiscal year ended April 30, 2016, consisting primarily of net borrowings from the ABL Facility of $85.0 million and proceeds from stock option exercises of $5.4 million, offset by payments of contingent consideration of $6.6 million, principal payments on long-term debt and capital lease obligations of $8.2 million, stock repurchases of $4.7 million after giving effect to the exercise of certain options and the repurchase of the related shares and debt issuance costs of $0.4 million incurred in connection with the exercise of the accordion feature of the ABL Facility

        Net cash provided by financing activities was $13.1 million for the fiscal year ended April 30, 2015, consisting primarily of net borrowings from the ABL Facility of $17.0 million. In the one month ended April 30, 2014, cash provided from financing activities was $750.9 million, which consisted of $546.5 million (net of original issue discount) received from the issuance of debt under the Term Loan Facilities and $224.1 million received from the sales of our common stock as a result of the Acquisition. In the eleven months ended March 31, 2014, cash used in financing activities of $16.9 million primarily consisted of net cash repayments on the 2010 Credit Facility of $13.8 million. For the fiscal year ended April 30, 2013, cash provided by financing activities of $5.4 million primarily consisted of borrowings of $9.5 million on the 2010 Credit Facility, partially offset by principal payments on long-term debt and capital lease obligations.

Adjusted Working Capital

        Adjusted working capital is an important measurement that we use in determining the efficiencies of our operations and our ability to readily convert assets into cash. Adjusted working capital represents current assets,

Table of Contents

excluding cash and cash equivalents, minus current liabilities, excluding current maturities of long-term debt. The material components of adjusted working capital for us include accounts receivable, inventory and accounts payable. Management of our adjusted working capital helps to ensure we can maximize our return and continue to invest in our operations for future growth. Comparing our adjusted working capital to that of other companies in our industry may be difficult, as other companies may calculate adjusted working capital differently than we do. A summary of working capital and adjusted working capital as of April 30, 2016, 2015 and 2014 is shown in the following table:

        Our adjusted working capital increased by $47.0 million from April 30, 2015 to April 30, 2016 as a result of an increase in working capital of $41.9 million and current maturities of long term debt of $11.9 million, offset by a $6.8 million increase in cash and cash equivalents. Working capital increased by $41.9 million as a result of an increase in trade accounts and notes receivable and inventories, net of $55.9 million and $18.2 million, respectively, partially offset by an increase in accounts payable of $13.7 million and a decrease in other current assets of $18.4 million. The increase in trade accounts and notes receivable was related to increases in sales and to working capital needs related to acquisitions.

        Our adjusted working capital increased by $10.7 million from April 30, 2014 to April 30, 2015 as a result of an increase in trade accounts and notes receivable and inventories, net of $25.7 million and $12.3 million, respectively, partially offset by an increase in accounts payable of $7.7 million and an increase in other current liabilities, net (excluding cash and cash equivalents and current maturities of long-term debt), of $19.5 million. The increases in trade accounts and notes receivable, inventories, net and accounts payable were related to increases in sales and to working capital needs related to acquisitions. The increase in other current liabilities, net (excluding cash and cash equivalents and current maturities of long-term debt) was related to increases in accrued compensation and employee benefits of $12.2 million and other accrued liabilities of $26.7 million, partially offset by an increase to prepaid expenses and other current assets of $23.7 million. Working capital decreased $27.3 million from April 30, 2014 to April 30, 2015 as a result of the same factors which impacted adjusted working capital combined with the decrease in cash and cash equivalents of $20.4 million and the increase in current maturities of long-term debt of $17.6 million.

Our Credit Facilities

        Our long-term debt consisted of the following at April 30, 2016 and 2015:

Acquisition Debt (Successor)

        On April 1, 2014, our wholly-owned subsidiaries, GYP Holdings II Corp., as parent guarantor, and GYP Holdings III Corp., as borrower, entered into the Term Loan Facilities in the aggregate amount of $550.0 million in connection with the Acquisition. The proceeds from the Term Loan Facilities were used to (i) repay all amounts

Table of Contents

outstanding under the 2010 Credit Facility in the amount of $86.1 million, (ii) pay the Acquisition purchase price and (iii) pay related fees and expenses.

        The First Lien Facility was issued in an original aggregate principal amount of $388.1 million (net of $1.9 million of original issue discount). The Second Lien Facility was issued in an original aggregate principal amount of $158.4 million (net of $1.6 million of original issue discount). At April 30, 2016, the borrowing interest rates for the First Lien Facility and Second Lien Facility were 4.75% and 7.75%, respectively. Accrued interest, presented within other accrued expenses and current liabilities in our consolidated balance sheets, was approximately $0.2 million and $1.1 million at April 30, 2016 and 2015, respectively, and cash paid for interest was $32.1 million and $30.3 million in the fiscal year ended April 30, 2016 and 2015, respectively. The First Lien Facility permits us to add one or more incremental term loans up to a fixed amount of $100.0 million (shared with the Second Lien Facility) plus a certain amount depending on a secured first lien leverage ratio test included in the First Lien Facility. The Second Lien Facility permits us to also add one or more incremental term loans up to a fixed amount of $100.0 million (shared with the First Lien Facility) plus a certain amount depending on a secured leverage ratio test included in the Second Lien Facility. The First Lien Facility bears interest at LIBOR (subject to a floor of 1.00%) plus a borrowing margin of 3.75%. The Second Lien Facility bears interest at LIBOR (subject to a floor of 1.00%) plus a borrowing margin of 6.75%. The First Lien Facility amortizes in nominal quarterly installments equal to approximately $975 thousand or 0.25% of the original aggregate principal amount of the First Lien Facility and matures on April 1, 2021. The Second Lien Facility has no amortization and matures on April 1, 2022. Provided that the individual affected lenders agree accordingly, the maturities of the term loans under the Term Loan Facilities, may, upon our request and without the consent of any other lender, be extended. Further, we are not subject to any financial maintenance covenants pursuant to the terms of the Term Loan Facilities.

        In connection with our IPO on June 1, 2016, we used net proceeds of $157.2 million together with cash on hand to repay the $160.0 million principal amount of our term loan debt outstanding under the Second Lien Facility, which was a payment in full of the entire loan balance due under the Second Lien Facility. See "—Recent Events."

Asset Based Lending Facility (Successor)

        The asset-based revolving credit facility, or the ABL Facility, entered into on April 1, 2014, provides for revolving loans and the issuance of letters of credit up to an initial maximum aggregate principal amount of $200.0 million. Extensions of credit under the ABL Facility will be limited by a borrowing base calculated periodically based on specified percentages of the value of eligible inventory and eligible accounts receivable, subject to certain reserves and other adjustments. As of April 30, 2016 and 2015, there were approximately $0.4 million and $0.3 million accrued interest payable, respectively, on the ABL Facility. In the fiscal year ended April 30, 2016 and 2015, we paid interest and other fees of $1.9 million and $0.9 million, respectively, on the ABL Facility.

        In February 2016, we amended our ABL Facility to exercise the $100.0 million accordion feature of the ABL Facility which increased the aggregate revolving commitments from $200.0 million to $300.0 million and increased the sublimit for same day swing line borrowings from $20.0 million to $30.0 million. The other terms of the ABL Facility remain unchanged.

        At our option, the interest rates applicable to the loans under the ABL Facility are based at LIBOR or Base Rate, plus, in each case, an applicable margin. The margins applicable for each elected interest rate are subject to a pricing grid, as defined in the ABL Facility Credit Agreement, based on average daily availability for the most recent fiscal quarter. The ABL Facility also contains an unused commitment fee subject to utilization, as included in the ABL Facility Credit Agreement.

        The ABL Facility will mature on April 1, 2019 unless the individual affected lenders agree to extend the maturity of their respective loans under the ABL Facility upon our request and without the consent of any other lender. The ABL Facility contains a cross default provision with the Term Loan Facility.

        As of April 30, 2016, approximately $187.2 million was available for future borrowings under our ABL Facility, after giving effect to the amendment to the ABL Facility.

Collateral under the ABL Facility and Term Loan Facilities

        The ABL Facility is collateralized by (a) first priority perfected liens on our (i) accounts receivable, (ii) inventory, (iii) deposit accounts, (iv) cash and cash equivalents, (v) tax refunds and tax payments, (vi) chattel paper and (vii) documents, instruments, general intangibles, securities accounts, books and records, proceeds and supporting obligations related to each of the foregoing, subject to certain exceptions (collectively, "ABL Priority Collateral") and (b) third priority perfected liens on our remaining assets not constituting ABL Priority Collateral, subject to customary exceptions (collectively, "Term Priority Collateral").

        The First Lien Facility and the Second Lien Facility are collateralized by (a) first priority liens and second priority liens, respectively, on the Term Priority Collateral and (b) second priority liens and third priority liens, respectively, on the ABL Priority Collateral, subject to customary exceptions.

Prepayments under the ABL Facility and Term Loan Facilities

        The ABL Facility may be prepaid at our option at any time without premium or penalty and will be subject to mandatory prepayment if the outstanding ABL Facility exceeds the lesser of the (i) borrowing base and (ii) the aggregate amount of commitments. Mandatory prepayments do not result in a permanent reduction of the lenders' commitments under the ABL Facility.

        The Term Loans under the Term Loan Facilities may be prepaid at any time without penalty. Under certain circumstances and subject to certain exceptions, the Term Loan Facilities will be subject to mandatory prepayments in the amount equal to: 100% of the net proceeds of certain assets sales and issuances or incurrences of non-permitted indebtedness; and 50% of annual excess cash flow for any fiscal year, such percentage to decrease to 25% or 0% depending on the attainment of certain total leverage ratio targets.

        As of April 30, 2016 and 2015, there was no requirement for a prepayment related to excess cash flow nor were there fees related to the repayment of the Second Lien Facility. See "—Recent Events."

Guarantees

        GYP Holdings III Corp. is the borrower under Term Loan Facilities and the lead borrower under the ABL Facility. Our wholly-owned subsidiary, GYP Holdings II Corp. (and direct parent of GYP Holdings III Corp.) guarantees our payment obligations under the Term Loan Facilities and the ABL Facility. Certain of our other subsidiaries are co-borrowers under the ABL Facility and guarantee our payment obligations under the Term Loan Facilities.

Covenants under the ABL Facility and Term Loan Facilities

        The ABL Facility contains certain affirmative covenants, including financial and other reporting requirements. We were in compliance with all such covenants at April 30, 2016 and 2015.

        The Term Loan Facilities contain a number of covenants that limit our ability and the ability of our restricted subsidiaries, as described in the Term Loan Credit Agreements, to: (i) incur more indebtedness; (ii) pay dividends, redeem stock or make other distributions; (iii) make investments; (iv) create restrictions on the ability of our restricted subsidiaries to pay dividends to us or make other intercompany transfers; (v) create liens securing indebtedness; (vi) transfer or sell assets; (vii) merge or consolidate; (viii) enter into certain transactions with our affiliates; and (ix) prepay or amend the terms of certain indebtedness. We were in compliance with all restrictive covenants at April 30, 2016 and 2015.

Events of Default under the ABL Facility and Term Loan Facilities

        The ABL Facility and Term Loan Facilities provide for customary events of default, including non-payment of principal, interest or fees, violation of covenants, material inaccuracy of representations or warranties, specified cross default to other material indebtedness, certain bankruptcy events, certain ERISA events, material invalidity of guarantees or security interest, material judgments and changes of control.

Asset Based Lending Facility (Predecessor)

        In conjunction with the Acquisition, the outstanding balance of our 2010 Credit Facility was paid in full and unamortized deferred financing charges of $1.6 million were written off as part of the purchase price accounting.

Installment Notes

        The installment note for the one month ended April 30, 2014 represents the outstanding note for the payout of the stock appreciation rights. The installment notes as of April 30, 2015 represent notes for subsidiary stock repurchases from shareholders and notes for the payout of stock appreciation rights. The installment notes as of April 30, 2016 represent notes for subsidiary stock repurchases from shareholders, notes for the payout of stock appreciation rights and a note to a seller of an acquired business.

Contractual Obligations

        We enter into long-term obligations and commitments in the normal course of business, primarily debt obligations and non-cancelable operating leases. As of April 30, 2016, after giving effect to our IPO, our contractual cash obligations over the next several periods are as follows:

        We may, from time to time, repurchase or otherwise retire or extend our debt and/or take other steps to reduce our debt or otherwise improve our financial position. These actions may include open market debt repurchases, negotiated repurchases, other retirements of outstanding debt and/or opportunistic refinancing of debt. The amount of debt that may be repurchased or otherwise retired or refinanced, if any, will depend on market conditions, trading levels of our debt, our cash position, compliance with debt covenants and other considerations. Our affiliates may also purchase our debt from time to time, through open market purchases or other transactions. In such cases, our debt may not be retired, in which case we would continue to pay interest in

accordance with the terms of the debt, and we would continue to reflect the debt as outstanding in our consolidated balance sheets.

        We lease certain office and warehouse facilities and equipment, some of which provide renewal options. Rent expense for operating leases, which may have escalating rents over the terms of the leases, is recorded on a straight-line basis over the minimum lease terms. Rent expense under operating leases approximated $41.7 million, $29.9 million, $1.5 million and $19.9 million for the fiscal years ended April 30, 2016 and 2015, the one month ended April 30, 2014 and the eleven months ended March 31, 2014, respectively. As existing leases expire, we anticipate such leases will be renewed or replaced with other leases that are substantially similar in terms, which are consistent with market rates at the time of renewal.

Off Balance Sheet Arrangements

        At April 30, 2016, we did not have any relationships with unconsolidated entities or financial partnerships for the purpose of facilitating off-balance sheet arrangements or for other contractually narrow or limited purposes.

Critical Accounting Policies

        Our discussion and analysis of operating results and financial condition are based upon our audited financial statements included elsewhere in this Annual Report on Form 10-K. The preparation of our financial statements, in accordance with GAAP, requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, net sales, expenses and related disclosures of contingent assets and liabilities. We base our estimates on past experience and other assumptions that we believe are reasonable under the circumstances, and we evaluate these estimates on an ongoing basis. Our critical accounting policies are those that materially affect our consolidated financial statements and involve difficult, subjective or complex judgments by management. Although these estimates are based on management's best knowledge of current events and actions that may impact us in the future, actual results may be materially different from the estimates.

        We believe the following critical accounting policies are affected by significant judgments and estimates used in the preparation of our consolidated financial statements and that the judgments and estimates are reasonable.

Use of Estimates

        The preparation of consolidated financial statements, in conformity with GAAP, requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Revenue Recognition

        We recognize revenue at the point of sale or upon delivery to the customer's site when the following four basic criteria are met:

•

persuasive evidence of an arrangement exists;



•

delivery has occurred or services have been rendered;



•

the price to the buyer is fixed or determinable; and



•

collectibility is reasonably assured.

        Revenue, net of estimated returns and allowances, is recognized when sales transactions occur and title is passed, the related product is delivered, and includes any applicable shipping and handling costs invoiced to the customer. The expense related to such costs is included in "Selling, general and administrative" expenses.

Allowance for Doubtful Accounts

        We maintain an allowance for doubtful accounts for estimated losses due to the failure of our customers to make required payments. Management believes the accounting estimate related to the allowance for doubtful accounts is a "critical accounting estimate" as it involves complex judgments about our customers' ability to pay.

        The allowance for doubtful accounts is based on an assessment of individual past due accounts, historical write-off experience, accounts receivable aging, customer disputes and the business environment. Account balances are charged off when the potential for recovery is considered remote.

        Management believes the allowance amounts recorded, in each instance, represent its best estimate of future outcomes. If there is a deterioration of a major customer's financial condition, if we become aware of additional information related to the creditworthiness of a major customer, or if future actual default rates on trade receivables in general differ from those currently anticipated, we may have to adjust its allowance for doubtful accounts, which would affect earnings in the period the adjustments were made. Based on our evaluation, we record reserves to reduce the related receivables to amounts we reasonably believe are collectible.

Inventories

        Inventories consist primarily of materials purchased for resale, and include wallboard, ceilings, steel framing and other specialty building products. The cost of our inventories is determined by the moving average cost method, which approximates the first-in, first-out approach. We monitor our inventory levels by branch and record provisions for excess inventories based on slower moving inventory. We define potential excess inventory as the amount of inventory on hand in excess of the historical usage, excluding items purchased in the last 12 months. We then review our most recent history of sales and adjustments of such excess inventory and apply our judgment as to forecasted demand and other factors, including liquidation value, to determine the required adjustments to net realizable value. In addition, at the end of each fiscal year, we evaluate our inventory at each branch and write-off and dispose of obsolete products. Our inventories are generally not susceptible to technological obsolescence.

        During the fiscal year, we perform periodic cycle counts and write-off excess or damaged inventory as needed. At fiscal year-end, we take a physical inventory count and record any necessary additional write-offs.

Long-Lived Assets and Goodwill

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

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

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

        During the fourth quarters of fiscal 2016, fiscal 2015 and full year 2014, we performed our annual impairment assessments of goodwill, which did not indicate that an impairment existed. During each assessment, we determined that the fair value of our reporting units which contain goodwill exceeded their carrying values.

        For impairment testing of long-lived assets, we identify asset groups at the lowest level for which identifiable cash flows are largely independent of the cash flows of other groups of assets and liabilities. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to the estimated

57

---

Table of Contents

undiscounted future cash flow expected to be generated by the assets. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized by the amount by which the carrying amount of the asset exceeds the estimated fair value of the asset.

        As discussed above, changes in management intentions, market events or conditions, projected future net sales, operating results, cash flow of our reporting units and other similar circumstances could affect the assumptions used in the impairment tests. Although management currently believes that the estimates used in the evaluation of goodwill and other long-lived assets are reasonable, differences between actual and expected net sales, operating results and cash flow could cause these assets to be impaired. If any asset were determined to be impaired, this could have a material adverse effect on our results of operations and financial position, but not our cash flow from operations.

        Significant estimates and assumptions inherent in the valuations reflect a consideration of other marketplace participants and include the amount and timing of future cash flows (including expected growth rates and profitability), the underlying product or technology life cycles, the economic barriers to entry and the discount rate applied to the cash flows. Unanticipated market or macroeconomic events and circumstances may occur that could affect the accuracy or validity of the estimates and assumptions.

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

Equity-Based Compensation

        Prior to our IPO, we utilized the Black-Scholes option-pricing model to estimate the grant-date fair value of all stock options. The Black-Scholes option-pricing model requires the use of weighted average assumptions for estimated expected volatility, estimated expected term of stock options, risk-free rate, estimated expected dividend yield and the fair value of the underlying common stock at the date of grant. Because we did not have sufficient history to estimate the expected volatility of our common stock price, expected volatility was based on the average volatility of peer public entities that are similar in size and industry. We estimated the expected term of all stock options based on previous history of exercises. The risk-free rate was based on the U.S. Treasury yield curve in effect at the time of grant for the expected term of the stock option. The expected dividend yield was 0% as we have not declared any common stock dividends to date and do not expect to declare common stock dividends in the near future. The fair value of the underlying common stock at the date of grant was determined based on a valuation of our common stock. In the absence of a public trading market prior to our IPO, we determined the fair value of our common stock utilizing methodologies, approaches and assumptions consistent with the American Institute of Certified Public Accountants Practice Aid, "Valuation of Privately-Held-Company Equity Securities Issued as Compensation." Our approach considered contemporaneous common stock valuations in determining the equity value of our company using a weighted combination of various methodologies, each of which can be categorized under either of the following two valuation approaches: the income approach and the market approach. The assumptions used in calculating the fair value of stock-based payment awards represented our best estimates, but these estimates involved inherent uncertainties and the application of management judgment.

        We estimated forfeitures based on our historical analysis of actual stock option forfeitures and employee turnover. Actual forfeitures are recorded when incurred and estimated forfeitures are reviewed and adjusted at

least annually. The weighted average assumptions used in the Black-Scholes option-pricing model for the fiscal year ended April 30, 2015 are set forth below:

        In the fiscal year ended April 30, 2016, we did not issue any stock option awards. In the fiscal year ended April 30, 2015, we issued 2,824,050 stock option awards to employees that vest based on service only. The weighted average grant date fair value of each stock option was $4.73 and the aggregate fair value of options outstanding and the aggregate fair value of options vested was $8.8 million and $5.3 million, respectively. All of these awards vest over a four-year period. Additionally, all these options could vest earlier in the event of a change in control, merger or other acquisition. This expense is recorded on an accelerated basis over the requisite service period of each separate vesting tranche. Equity-based compensation expense related to stock option awards was $2.7 million in the fiscal year ended April 30, 2016 and $6.5 million for the fiscal year ended April 30, 2015 and was included as a component of "Selling, general and administrative" expenses in our consolidated statements of operations and comprehensive income (loss). In fiscal 2016, we also recognized related income tax benefits of $2.6 million, which has been partially offset by a valuation allowance. At April 30, 2016 and 2015, the unrecognized compensation expense related to stock option awards was $2.3 million and $5.6 million, respectively, with a remaining weighted average life of 2.0 years and 3.1 years, respectively.

Subsidiary Equity-Based Deferred Compensation Arrangements

        Some of our operating subsidiaries sponsor deferred compensation arrangements that entitle selected employees of those subsidiaries to participate in increases in the adjusted book value of a specified number of shares of common stock of those subsidiaries. Adjusted book value for this purpose generally means the book value of the relevant shares, as increased, or decreased, to reflect those shares' ratable portion of any annual earnings, or losses, of the relevant subsidiary (based on the total number of outstanding shares of the relevant subsidiary). Employees participate in these deferred compensation arrangements in one or more of three ways: through cash-based stock appreciation rights (described below under the heading "—Stock appreciation rights"), by holding common stock of the applicable subsidiary (described below under the heading "—Liabilities to noncontrolling interest holders") and/or through deferred compensation programs (described below under the heading "—Deferred compensation"). As of April 30, 2016, in accordance with the provisions of the transition guidance set forth in ASC Topic 718, Compensation—Stock Compensation ("ASC 718"), the estimated fair values of these arrangements are reflected as liabilities. The determination of fair value is a significant estimate, which is based on assumptions including the expected book value of the subsidiary per share at the time of redemption and the expected termination date of each award holder. To determine the expected book value of the subsidiary at redemption date, we have used a lognormal binomial method. Significant inputs to this estimate include historical book values of the subsidiaries, our expected incremental borrowing rate, the expected retirement age of certain individuals and the expected volatility of the underlying book values of the subsidiary's equity. This estimate is, by its nature, subjective and involves a high degree of judgment and assumptions. These assumptions may have a significant effect on our estimates of fair value, and the use of different assumptions, as well as changes in market conditions, could have a material effect on our results of operations or financial condition. As a result of the transition guidance stated within ASC 718, we have recorded these liability awards at fair value as of April 30, 2016. The impact of this guidance was recognized as a decrease to retained earnings as of April 30, 2016. The total impact of applying the transition guidance, net of taxes, was $3.2 million. The arrangements are described in further detail below:

        Stock appreciation rights.    Certain subsidiaries have granted stock appreciation rights to certain employees under which payments are dependent on the appreciation in the adjusted book value of a specified number of shares of the applicable subsidiary. Settlements of the awards can be made in a combination of cash or installment notes, generally paid over four years, upon certain terminations of employment. Vesting periods vary by grant date and range from fiscal 2016 to fiscal 2018.

        Liabilities to noncontrolling interest holders.    As described in Note 14, "Stock Appreciation Rights, Deferred Compensation and Redeemable Noncontrolling Interests" of Part II, Item 8 of this Annual Report on Form 10-K, noncontrolling interests were issued to certain employees of the subsidiaries in the form of common stock. All of these noncontrolling interest awards are subject to buy-sell agreements that require the stock to be redeemed for its adjusted book value, subject in certain cases to an agreed upon minimum value, only upon termination of employment. These instruments are redeemed in cash, typically in annual installments over the five years following termination of employment.

        In connection with the Acquisition, noncontrolling interest holders had the option to reinvest their ownership interests in the subsidiaries into GMS Inc. Noncontrolling interests of $32.5 million were reinvested into GMS Inc.

        Deferred compensation.    During fiscal 2014, each employee who held redeemable noncontrolling interests as described above was granted a deferred compensation obligation entitling the employee to a payment based on a percentage of the adjusted book value of his or her associated noncontrolling interest at the time of payment. These deferred compensation obligations become payable only upon the employee's death, disability, termination without cause or retirement. The obligations are paid in cash, usually in annual installments over the five years following termination of employment.

Income Taxes

        Income taxes are accounted for in accordance with ASC 740, "Income Taxes", which requires the use of the asset and liability method. Deferred tax assets and liabilities are recognized based on the difference between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Inherent in the measurement of deferred balances are certain judgments and interpretations of existing tax law and published guidance as applicable to our operations.

        We evaluate our deferred tax assets to determine if valuation allowances are required. In assessing the realizability of deferred tax assets, we consider both positive and negative evidence in determining whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The primary negative evidence considered includes the cumulative operating losses generated in prior periods. The primary positive evidence considered includes the reversal of deferred tax liabilities related to depreciation and amortization that would occur within the same jurisdiction and during the carry-forward period necessary to absorb the federal and state net operating losses and other deferred tax assets. The reversal of such liabilities would utilize the federal and state net operating losses and other deferred tax assets.

        We record amounts for uncertain tax positions that management believes are supportable, but are potentially subject to successful challenge by the applicable taxing authority. Consequently, changes in our assumptions and judgments could materially affect amounts recognized related to income tax uncertainties and may affect our results of operations or financial position. We believe our assumptions for estimates continue to be reasonable, although actual results may have a positive or negative material impact on the balances of such tax positions. Historically, the variation of estimates to actual results is immaterial and material variation is not expected in the future.

Vendor Rebates

        Typical arrangements with our vendors provide for us to receive a rebate of a specified amount after we achieve any of a number of measures generally related to the volume of our purchases over a period of time. We reserve these rebates to effectively reduce our cost of sales in the period in which we sell the product. Throughout the year, we estimate the amount of rebates receivable for the periodic programs based upon the expected level of purchases. We continually revise these estimates to reflect actual rebates earned based on actual and projected purchase levels. If we fail to achieve a measure which is required to obtain a vendor rebate, we will have to record a charge in the period in which we determine the criteria or measure for the vendor rebate will not be met to the extent the vendor rebate was estimated and included as a reduction to cost of sales. Historically, our actual rebates have been within our expectations used for our estimates.

Derivative Instruments

        We enter into interest rate derivative agreements, with the objective of minimizing the risks and costs associated with financing activities, as well as to maintain an appropriate mix of fixed- and floating-rate debt.

        For derivative instruments designated as hedges for accounting purposes, we record the effective portions of changes in their fair value, net of taxes, in "Comprehensive income (loss)" to the extent the derivative is considered perfectly effective in achieving offsetting changes in fair value or cash flows attributable to the risk being hedged, until the hedged item is recognized in earnings (commonly referred to as the "hedge accounting" method).

        The effectiveness of the hedges is periodically assessed by management during the lives of the hedges by: (i) comparing the current terms of the hedges with the related hedged debt to assure they continue to coincide and (ii) through an evaluation of the ability of the counterparties to the hedges to honor their obligations under the hedges. Any ineffective portions of the hedges are recognized in earnings through interest expense, financing costs and other expenses.

        During the year ended April 30, 2015, we elected to designate a derivative instrument as a cash flow hedge in accordance with ASC 815. This instrument is an interest rate cap on quarterly resetting 3-month LIBOR, based on a strike rate of 2.0% and payable quarterly. This instrument effectively caps the interest rate at 5.75% on an initial notional amount of $275 million of our variable rate debt obligation under the First Lien Facility, or any replacement facility with similar terms. The interest rate cap was purchased for $4.6 million on October 31, 2014, designated as a hedge on January 31, 2015 and expires on October 31, 2018.

        This derivative instrument is recorded in the consolidated balance sheet as of April 30, 2016 as an asset at its fair value of $0.3 million within "Other assets". The valuation of this instrument was determined using widely accepted valuation techniques including a discounted cash flow analysis on the expected cash flows of each derivative. This analysis reflected the contractual terms of the derivatives, including the period to maturity, and used observable market-based inputs, including interest rate curves and implied volatilities.

        The decrease in fair value of the instrument from the purchase date to the date of the hedge was $2.5 million and is reflected in "Change in fair value of financial instruments" on our consolidated statements of operations and comprehensive income (loss) for the year ended April 30, 2015. The increase in fair value from the effective hedge date to April 30, 2015 was $10 thousand and was recorded in "Increase in fair value of financial instrument, net of tax." The decrease in fair value from April 30, 2015 to April 30, 2016 was $1.2 million and was recorded in "Decrease in fair value of financial instrument, net of tax." We believe there have been no material changes in the creditworthiness of the counterparty to this cap agreement and believe the risk of nonperformance by such party is minimal.

        For derivatives that do not qualify or are not designated as hedging instruments for accounting purposes, changes in fair value are recorded in current period earnings, commonly referred to as the "mark-to-market" method. Prior to full year 2014, we entered into an interest-rate swap agreement as a fixed-rate payor to mitigate interest-rate risk associated with floating interest rate borrowings under our revolving credit facility on an initial notional amount of $35.0 million. Per the terms of the contract, the Predecessor received fixed interest of 0.69% in exchange for floating interest indexed to the one-month LIBOR rate. Changes in fair value resulted in a gain of $0.2 million for the eleven month period ended March 31, 2014 and are recognized in our consolidated statements of operations and comprehensive income (loss), in "Other income, net." The interest rate swap was terminated in the eleven month period ended March 31, 2014 with a penalty of $0.1 million and interest of $16 thousand recorded in "Other income, net" in our consolidated statements of operations and comprehensive income (loss).

Newly Issued Accounting Pronouncements

        Presentation of an unrecognized tax benefit—In July 2013, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2013-11, "Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carry-forward, a Similar Tax Loss, or a Tax Credit Carry-forward Exists" ("ASU 2013-11"),

61

Table of Contents

which resolves diversity in practice on the financial statement presentation of an unrecognized tax benefit when a net operating loss carry-forward, a similar tax loss, or a tax credit carry-forward exists. An unrecognized tax benefit, or a portion of an unrecognized tax benefit, should be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carry-forward, a similar tax loss, or a tax credit carryforward, except in certain situations, as defined in ASU 2013-11. The amendments in ASU 2013-11 are effective prospectively for fiscal years, and interim periods within those years, beginning after December 15, 2013. We adopted ASU 2013-11 on May 1, 2014. The adoption of this standard did not materially impact our financial position, results of operations, or cash flows.

        Discontinued operations—In April 2014, the FASB issued ASU No. 2014-08, "Reporting discontinued operations and disclosure of disposals of components of an entity" ("ASU 2014-08"). The amended guidance requires that a disposal representing a strategic shift that has (or will have) a major effect on an entity's financial results or a business activity classified as held for sale should be reported as discontinued operations. The amendments also expand the disclosure requirements for discontinued operations and add new disclosures for individually significant dispositions that do not qualify as discontinued operations. The amendments are effective prospectively for fiscal years, and interim reporting periods within those years, beginning on or after December 15, 2014 (early adoption were permitted only for disposals that have not been previously reported). The impact on us of adopting ASU 2014-08 will depend on the nature and size of future disposals, if any, of a component of ours after the effective date. We had elected to early adopt ASU 2014-08 effective May 1, 2014. As a result of the adoption of this standard, the classification of a disposal made in fiscal 2015 that did not represent a strategic shift in our direction or have a major impact on our financial position or results of operations was not reported as a discontinued operation.

        Revenue recognition—In May 2014, the FASB issued ASU No. 2014-09, "Revenue from contracts with customers" ("ASU 2014-09"). The amended guidance outlines a single comprehensive revenue model for entities to use in accounting for revenue arising from contracts with customers. The guidance supersedes most current revenue recognition guidance, including industry-specific guidance. The core principle of the revenue model is that "an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services." Entities have the option of using either a full retrospective or modified approach to adopt the guidance. In July 2015, the FASB decided on a one-year delay in the effective date of ASU 2014-09, to be effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period, and a permission to early adopt for interim and annual periods beginning after December 15, 2016. We are currently evaluating the impact of adopting ASU 2014-09.

        Going Concern—In August 2014, the FASB issued ASU 2014-15, "Disclosure of Uncertainties about an Entity's Ability to Continue as a Going Concern" ("ASU 2014-15"), which requires management to evaluate whether there are conditions or events that raise substantial doubt about an organization's ability to continue as a going concern and to provide related footnote disclosures. ASU 2014-15 is effective for interim and annual reporting periods beginning after December 15, 2016. Early adoption is permitted. We are currently evaluating the impact the adoption of this ASU will have on our consolidated financial statements.

        Debt Issuance Costs—In April 2015, the FASB issued ASU 2015-03, "Simplifying the Presentation of Debt Issuance Costs" ("ASU 2015-03") which changes the presentation of debt issuance costs in financial statements. Under ASU 2015-03, an entity presents such costs in the balance sheet as a direct deduction from the related debt liability rather than as an asset. Amortization of the costs is reported as interest expense. The guidance is effective prospectively for fiscal years, and interim reporting periods within those years, beginning on or after December 15, 2015. Early adoption is permitted and upon adoption, the guidance must be applied retroactively to all periods presented in the financial statements. Management has early adopted the standard and retroactively applied it to all periods presented in the financial statements. The adoption of this standard did not materially impact our financial position, results of operations, or cash flows.

        Business Combinations—In September 2015, the FASB issued ASU No. 2015-16, "Simplifying the accounting for measurement-period adjustments" ("ASU 2015-16"). The amended guidance requires that an acquirer recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. The amendments are effective prospectively for the fiscal years, and interim reporting periods within those years, beginning on or after December 15, 2015 (early adoption were permitted only for financial statements that have not been issued). Management has early adopted the standard. The adoption of this standard did not materially impact our financial position, results of operations, or cash flows.

        Deferred Taxes—In November 2015, the FASB issued ASU No. 2015-17, "Balance Sheet Classification of Deferred Taxes ("ASU 2015-17"). This amendment changes how deferred taxes are recognized by eliminating the requirement of presenting deferred tax liabilities and assets as current and noncurrent on the balance sheet. Instead, the requirement will be to classify all deferred tax liabilities and assets as noncurrent. ASU 2015 17 is effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period, with earlier adoption permitted. ASU 2015-17 can be adopted either prospectively or retrospectively to all periods presented. The Company is in the process of determining the method of adoption and assessing the impact ASU 2015-17 will have on its consolidated financial statements.

        Leases—In February 2016, the FASB issued ASU No. 2016-02, "Leases" ("ASU 2016-02"). The new standard establishes a right-of-use (ROU) model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with such classification affecting the pattern of expense recognition in the statement of operations. The new standard is effective for our fiscal year beginning May 1, 2019, including interim reporting periods within that fiscal year. A modified transition approach is required for lessees for capital and operating leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. While we are still evaluating the impact of our pending adoption of the new standard on our consolidated financial statements, we expect that upon adoption, the recognition of ROU assets and liabilities could be material.

        Equity Compensation—In March 2016, the FASB issued ASU 2016-09, "Compensation—Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting" ("ASU 2016-09"). Several aspects of the accounting for share-based payment award transactions are simplified, including: (a) income tax consequences; (b) classification of awards as either equity or liabilities; (c) forfeitures; and (d) classification on the statement of cash flows. The amendments are effective for public companies for annual periods beginning after December 15, 2016, and interim periods within those annual periods. Early adoption is permitted for any interim or annual period. We are currently in the process of evaluating the impact of the adoption on our consolidated financial statements.

Non-GAAP Financial Measures

Adjusted EBITDA

        The following is a reconciliation of our net income (loss) to Adjusted EBITDA for the fiscal years ended April 30, 2016 and 2015, the one month ended April 30, 2014 and the eleven months ended March 31, 2014, as well as the calculation of Adjusted EBITDA for the full year ended April 30, 2014. EBITDA, Adjusted EBITDA and Adjusted EBITDA margin are non-GAAP measures. See Item 6, "Selected Financial Data," for how we define and calculate Adjusted EBITDA and Adjusted EBITDA margin as non-GAAP measures and a description of why we believe these measures are important.

        The following is the calculation of Adjusted EBITDA for the full year ended April 30, 2014. As discussed above, the change in basis resulting from the Acquisition did not impact Adjusted EBITDA. Although this presentation of Adjusted EBITDA on a combined basis is not a presentation made in accordance with GAAP, we believe it provides a meaningful method of comparison to the other periods presented in this Annual Report on Form 10-K.

Adjusted Working Capital

        Adjusted working capital represents current assets, excluding cash and cash equivalents, minus current liabilities, excluding current maturities of long-term debt. Adjusted working capital is not a recognized term under GAAP and does not purport to be an alternative to working capital. Management believes that adjusted working capital is useful in analyzing the cash flow and working capital needs of the Company. We exclude cash and cash equivalents and current maturities of long-term debt to evaluate the investment in working capital required to support our business.

        The following is a reconciliation from working capital, the most directly comparable financial measure under GAAP, to adjusted working capital as of the dates presented:

Item 7A.    Quantitative and Qualitative Disclosures About Market Risk

Interest Rate Risk

        We are exposed to interest rate risk through fluctuations in interest rates on our debt obligations. A significant portion of our outstanding debt bears interest at variable rates. As a result, increases in interest rates could increase the cost of servicing our debt and could materially reduce our profitability and cash flows. However, we have entered into an interest rate cap on three-month U.S. dollar LIBOR based on a strike rate of 2.0%, which effectively caps the interest rate at 5.75% on an initial notional amount of $275.0 million of our variable rate debt obligation under the First Lien Facility, or any replacement facility with similar terms. Excluding the impact of this interest rate cap and the interest rate floor on the First Lien Facility, each 1% increase in interest rates on the First Lien Facility would increase our annual interest expense by approximately $3.8 million based on balances outstanding under the First Lien Facility as of April 30, 2016. Assuming the ABL Facility was fully drawn, each 1% increase in interest rates would result in a $3.0 million increase in our annual interest expense on the ABL Facility. We seek to manage exposure to adverse interest rate changes through our normal operating and financing activities, as well as through hedging activities, such as entering into interest rate derivative agreements, as discussed below under "—Derivative Financial Instruments." As of April 30, 2016, $101.9 million was outstanding under the ABL Facility and $187.2 million was available for future borrowings under the ABL Facility. In addition, we had $382.2 million outstanding under the First Lien Facility and $160.0 million outstanding under the Second Lien Facility. We used all of the net proceeds from our IPO, on June 1, 2016, together with cash on hand to repay the Second Lien Facility, which will reduce our interest expense in the future.

Derivative Financial Instruments

        We enter into interest rate derivative agreements, commonly referred to as caps or swaps, with the objective of minimizing the risks and costs associated with financing activities, as well as to maintain an appropriate mix of fixed- and floating-rate debt.

        On October 31, 2014, we entered into an interest rate cap on three-month U.S. dollar LIBOR based on a strike rate of 2.0%, which is payable quarterly. This instrument effectively caps the interest rate at 5.75% on an initial notional amount of $275.0 million of our variable rate debt obligation under the First Lien Facility, or any replacement facility with similar terms. The interest rate cap was purchased for $4.6 million on October 31, 2014, effectively hedged on January 31, 2015, and expires on October 31, 2018.

        This derivative instrument is recorded in "Other assets" on our consolidated balance sheets as of April 30, 2016 at its fair value of $0.3 million. The valuation of this instrument was determined using widely accepted valuation techniques, including discounted cash flow analysis on the expected cash flows of each derivative. This analysis reflected the contractual terms of the derivatives, including the period to maturity, and used observable market-based inputs, including interest rate curves and implied volatilities.

        The decrease in fair value of the instrument from the purchase date to effective hedge date was $2.5 million and is reflected in "Change in fair value of financial instruments" on our consolidated statements of operations and comprehensive income (loss) for the year ended April 30, 2015. The increase in fair value from the effective hedge date to April 30, 2015 was $10 thousand and was recorded in "Increase in fair value of financial instrument, net of tax," on our consolidated statements of operations and comprehensive income (loss). The decrease in fair value from April 30, 2015 to April 30, 2016 was $1.2 million and was recorded in "Decrease in fair value of financial instrument, net of tax," on our consolidated statements of operations and comprehensive income (loss). We believe there have been no material changes in the creditworthiness of the counterparty to this cap agreement and believe the risk of nonperformance by such party is minimal.

Impact of Inflation

        We believe that our results of operations are not materially impacted by moderate changes in the economic inflation rate. In general, we have historically been successful in passing on price increases from our vendors to our customers in a timely manner, although there is no assurance that we can successfully do so in the future.

Notes to Consolidated Financial Statements

Year Ended April 30, 2016 and 2015, Period From April 1, 2014 to April 30, 2014 (Successor) and
Period From May 1, 2013 to March 31, 2014 (Predecessor)

(in thousands of dollars, except for share and per share data)

1. Basis of Presentation, Business and Summary of Significant Accounting Policies

        The terms "we," "our," "us", "Successor" or the "Company" refer to GMS Inc. and its subsidiaries. When such terms are used in this manner throughout the notes to the consolidated financial statements, they are in reference only to the corporation, GMS Inc. and its subsidiaries, and are not used in reference to the Board of Directors, corporate officers, management, or any individual employee or group of employees.

        On April 1, 2014, GYP Holdings I Corp., or the Successor, acquired, through its wholly-owned entities, GYP Holdings II Corp. and GYP Holdings III Corp., all of the capital stock of Gypsum Management and Supply, Inc. (the "Predecessor"). Successor is majority owned by certain affiliates of AEA Investors LP, or "AEA", and certain of our other stockholders. We refer to this acquisition as the "Acquisition" and April 1, 2014 as the "Acquisition Date". We were previously known as GYP Holdings I Corp. and changed our name to GMS Inc. on July 6, 2015.

        As a result of the Acquisition and resulting change in control and changes due to the impact of purchase accounting, we are required to present separately the operating results for the Predecessor periods ending on or prior to March 31, 2014 and the Successor periods beginning on or after April 1, 2014. References throughout the notes to "Successor 2016" relate to the fiscal year ended April 30, 2016, references throughout the notes to "Successor 2015" relate to the fiscal year ended April 30, 2015, references throughout the notes to "Successor 2014" relate to the one month ended April 30, 2014 and references throughout the notes to "Predecessor 2014" relate to the eleven months ended March 31, 2014. The results of the Successor are not comparable to the results of the Predecessor.

        We have no independent operations and our only asset is our investment in the Predecessor.

Revision of Financial Statements

        During the preparation of the Annual Report on Form 10-K for the year ended April 30, 2016, the Company determined that an inappropriate statutory tax rate was used to value deferred tax liabilities related to certain assets purchased in the Acquisition as of April 1, 2014. This resulted in an understatement of "Deferred income taxes, net" and "Goodwill", as of April 30, 2015, and an overstatement of "Provision for (benefit from) income taxes" and an understatement of "Net income (loss)" for the year ended April 30, 2015. The Company assessed the materiality of the misstatement in accordance with SEC Staff Accounting Bulletin No. 99, Materiality, and concluded that this misstatement was not material to the Company's Consolidated Financial Statements for the prior periods and that amendments of previously filed reports were therefore not required. However, the Company determined that the impact of the corrections would be too significant to record during fiscal 2016. As such, the revision for the correction is reflected in the 2015 financial information in this Form 10-K filing. Disclosure of the revised amounts will also be reflected in future filings containing the applicable periods.

1. Basis of Presentation, Business and Summary of Significant Accounting Policies (Continued)

Business

        Founded in 1971, we are a distributor of specialty building products including wallboard, suspended ceilings systems, or ceilings, steel framing and other complementary specialty building products. We purchase products from a large number of manufacturers and then distribute these goods to a customer base consisting of wallboard and ceilings contractors and homebuilders, and to a lesser extent, general contractors and individuals. We have created a national footprint with more than 185 branches across 41 states.

Principles of Consolidation

        The Consolidated Financial Statements present the results of operations, financial position and cash flows of the Company and its subsidiaries. All material intercompany balances and transactions have been eliminated in consolidation. Results of operations of businesses acquired are included from their respective dates of acquisition.

Use of Estimates

        The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America ("GAAP") requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Revenue Recognition

        We recognize revenue at the point of sale or upon delivery to the customer's site when the following four basic criteria are met:

•

persuasive evidence of an arrangement exists;



•

delivery has occurred or services have been rendered;



•

the price to the buyer is fixed or determinable; and



•

collectibility is reasonably assured.

        Revenue, net of estimated returns and allowances, is recognized when sales transactions occur and title is passed, the related product is delivered, and includes any applicable shipping and handling costs invoiced to the customer. The expense related to such costs is included in "Selling, general and administrative" expenses in the accompanying Consolidated Statements of Operations and Comprehensive Income (Loss).

Cost of Sales

        "Cost of sales" reflects the direct cost of goods purchased from third parties, rebates earned from vendors, adjustments for inventory reserves, and the cost of inbound freight.

Operating Expenses

        "Operating expenses" include "Selling, general and administrative" expenses and "Depreciation and amortization". "Selling, general and administrative" expenses include expenses related to the delivery and

warehousing of our products, as well as employee compensation and benefits expenses for employees in our branches and yard support center, as well as other administrative expenses, such as legal, accounting, and IT costs. Included in "Selling, general and administrative" expenses are delivery expenses of $159,098, $128,381, $9,727 and $99,822 for Successor 2016, Successor 2015, Successor 2014 and Predecessor 2014, respectively. "Depreciation and amortization" expenses include depreciation expense on our property and equipment as well as amortization expense on our finite lived intangible assets.

Cash and Cash Equivalents

        The Company considers all highly liquid investments with a maturity of three months or less when purchased to be cash equivalents. The carrying values of cash and cash equivalents approximate their fair values due to the short-term nature of these investments.

Trade Accounts Receivable

        We maintain allowances for doubtful accounts for estimated losses due to the failure of our customers to make required payments, as well as allowances for sales returns and cash discounts.

        Our estimate of the allowance for doubtful accounts is based on an assessment of individual past due accounts, historical write-off experience, accounts receivable aging and the current economic trends. Account balances are written off when the potential for recovery is considered remote. Our estimates for cash discounts and returns are based on an analysis of historical writeoffs. Based on our evaluation, we have established estimated reserves for uncollectible accounts, returns and cash discounts of $8,607 and $8,633 as of April 30, 2016 and 2015, respectively.

Inventories

        "Inventories, net" consist of materials purchased for resale, and include wallboard, ceilings, steel framing and other specialty building products. The cost of our inventories is determined by the moving average cost method, which approximates the first-in, first-out approach. We monitor our inventory levels by branch and record provisions for excess inventories based on slower moving inventory. We define excess inventory as the amount of inventory on hand in excess of the historical usage, excluding items purchased in the last 12 months. We then review our most recent history of sales and adjustments of such excess inventory and apply our judgment as to forecasted demand and other factors, including liquidation value, to determine the required adjustments to net realizable value. In addition, at the end of each year, we evaluate our inventory at each branch and write off and dispose of obsolete products. Our inventories are generally not susceptible to technological obsolescence.

Vendor Rebates

        Typical arrangements with our vendors provide for us to receive a rebate of a specified amount after we achieve any of a number of measures generally related to the volume of our purchases over a period of time. We record these rebates to effectively reduce our cost of sales in the period in which we sell the product. Throughout the year, we estimate the amount of rebates receivable for the periodic programs based upon the expected level of purchases. We accrue for the receipt of vendor rebates based on purchases and also reduce inventory to reflect the deferral of cost of sales.

1. Basis of Presentation, Business and Summary of Significant Accounting Policies (Continued)

Property and Equipment

        "Property and equipment, net" is recorded at cost. Buildings, furniture, fixtures and equipment are depreciated using the straight-line method over the estimated useful lives of the assets. Expenditures for improvements and betterments, which extend the useful lives of assets, are capitalized while maintenance and repairs are charged to expense as incurred. Property and equipment obtained through acquisition are stated at estimated fair value as of the acquisition date, and are depreciated over their estimated remaining useful lives. Gains and losses related to the sale of property and equipment are recorded as "Selling, general and administrative" expenses.

        In the Successor and Predecessor periods, property and equipment is depreciated and amortized using the following estimated useful lives:

        Leased property and equipment meeting capital lease criteria are capitalized at the lower of the present value of the related lease payments or the fair value of the leased asset at the inception of the lease. Leasehold improvements and assets under capital leases are amortized using the straight-line method over the shorter of their estimated useful lives or the initial term of the related lease.

        Long-lived assets to be held and used are reviewed for impairment whenever facts and circumstances indicate that the carrying amount of an asset may not be recoverable. For impairment testing of long-lived assets, we identify asset groups at the lowest level for which identifiable cash flows are largely independent of the cash flows for other groups of assets and liabilities. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to the estimated undiscounted future cash flows expected to be generated by the assets. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized in an amount by which the carrying amount of the asset exceeds the estimated fair value of the asset.

        Assets are classified as held for sale if the Company commits to a plan to sell the asset within one year and actively markets the asset in its current condition for a price that is reasonable in comparison to its estimated fair value. Assets held for sale are stated at lower of depreciated cost or estimated fair value less expected disposition costs and are recorded within "Prepaid expenses and other current assets".

        During Successor 2016, Successor 2015 and Predecessor 2014, the Company recognized impairment losses of $373, $173 and $728, respectively, related to land and buildings held for sale. These losses were included in "Selling, general and administrative" expenses in the Consolidated Statements of Operations and Comprehensive Income (Loss) in Successor 2016, Successor 2015 and Predecessor 2014. The Company did not recognize any impairments in Successor 2014.

(in thousands of dollars, except for share and per share data)

1. Basis of Presentation, Business and Summary of Significant Accounting Policies (Continued)

Goodwill

        Goodwill represents the excess of purchase price over fair value of net assets acquired. We do not amortize goodwill, but do assess goodwill for impairment in the fourth quarter of each fiscal year or whenever events or circumstances indicate that it is "more likely than not" that the fair value of a reporting unit had dropped below its carrying value. For the fiscal 2016, fiscal 2015 and full year 2014 annual impairment tests, the fair values of our identified reporting units were estimated using a discounted cash flow ("DCF") analysis and a market comparable method, with each method being equally weighted in the calculation. There were no goodwill impairment charges recorded. See Note 6, "Goodwill and Intangible Assets," for a complete description of the Company's goodwill.

Intangible Assets

        The Company typically uses an income method to estimate the fair value of "Intangible assets", which is based on forecasts of the expected future cash flows attributable to the respective assets. Significant estimates and assumptions inherent in the valuations reflect a consideration of other marketplace participants and include the amount and timing of future cash flows (including expected growth rates and profitability), the underlying product or technology life cycles, the economic barriers to entry and the discount rate applied to the cash flows. Unanticipated market or macroeconomic events and circumstances may occur that could affect the accuracy or validity of the estimates and assumptions.

        Determining the useful life of an intangible asset also requires judgment. Certain intangibles are expected to have indefinite lives based on their history and the Company's plans to continue to support and build the acquired brands. Other acquired intangible assets such as customer relationships and other brand or trade names are expected to have definite useful lives. All of the Company's customer-related intangibles are expected to have determinable useful lives. The costs of determinable-lived intangibles are amortized over their estimated lives.

Deferred Financing Costs

        The Company capitalizes debt issuance costs and amortizes them over the term of the related debt. The Company uses the straight-line method to amortize debt issuance costs related to the ABL Facility (as defined below) while the effective interest method is used to amortize debt issuance costs related to the Term Loan Facilities (as defined below). Amortization of debt issuance costs is recorded in "Interest expense" within the Consolidated Statements of Operations and Comprehensive Income (Loss). Lender and third party deferred financing costs are reported as a reduction of the Term Loan Facilities of $11,147 and $13,311 as of April 30, 2016 and 2015, respectively, in the Consolidated Balance Sheets. Lender and third party deferred financing costs related to the ABL Facility are reported as an asset of $2,544 and $2,949 as of April 30, 2016 and 2015, respectively, in the Consolidated Balance Sheets. Amortization of these costs was $2,961, $2,907, $235 and $516 in Successor 2016, Successor 2015, Successor 2014 and Predecessor 2014, respectively.

Derivative Instruments

        The Derivative financial instruments are recognized as either assets or liabilities in the Consolidated Balance Sheets and measured at fair value. Derivatives that do not qualify as a hedge must be adjusted to fair value in earnings. If the derivative does qualify as a hedge, under the Financial Accounting Standards Board ("FASB") issued Accounting Standards Codificaiton ("ASC") Topic 815, "Derivatives and hedging", changes in the fair value

will either be offset against the change in fair value of the hedged assets, liabilities or firm commitments or recognized in accumulated other comprehensive income until the hedged item is recognized in earnings. The ineffective portion of a hedge's change in fair value is immediately recognized in earnings.

        We enter into interest rate derivative agreements, commonly referred to as caps or swaps, with the objective of minimizing the risks and costs associated with financing activities, as well as to maintain an appropriate mix of fixed-and floating-rate debt. These agreements are contracts to exchange variable-rate for fixed-interest rate payments over the life of the agreements.

        For derivative instruments designated as hedges per ASC 815, we record the effective portions of changes in their fair value, net of taxes, in "Comprehensive income (loss)" to the extent the derivative is considered perfectly effective in achieving offsetting changes in fair value or cash flows attributable to the risk being hedged, until the hedged item is recognized in earnings (commonly referred to as the "hedge accounting" method).

        The effectiveness of the hedges is periodically assessed by management during the lives of the hedges by: 1) comparing the current terms of the hedges with the related hedged debt to assure they continue to coincide and 2) evaluating the ability of the counterparties to the hedges to honor their obligations under the hedges. Any ineffective portions of the hedges are recognized in earnings through interest expense, financing costs and other expenses.

        During the year ended April 30, 2015, we elected to designate a derivative instrument as a cash flow hedge in accordance with ASC 815. This instrument is an interest rate cap on quarterly resetting 3-month LIBOR, based on a strike rate of 2.0% and payable quarterly. This instrument effectively caps the interest rate at 5.75% on an initial notional amount of $275,000 of our variable rate debt obligation under the First Lien Facility, or any replacement facility with similar terms. The interest rate cap was purchased for $4,638 on October 31, 2014, designated as a hedge on January 31, 2015, and expires on October 31, 2018.

        This derivative instrument is recorded in the Consolidated Balance Sheet as of April 30, 2016 and 2015, respectively, as an asset at its fair value of $271 and $2,160 within "Other assets". The valuation of this instrument was determined using widely accepted valuation techniques including a discounted cash flow analysis on the expected cash flows of the derivative. This analysis reflected the contractual terms of the derivatives, including the period to maturity, and used observable market-based inputs, including interest rate curves and implied volatilities.

        The decrease in fair value of the instrument from the purchase date to the date of hedge designation was $2,494 and is reflected in earnings through "Change in fair value of financial instruments" on the Consolidated Statements of Operations and Comprehensive Income (Loss). The increase in fair value from the effective hedge date to the year ended April 30, 2015 was $10 and was recorded in "Increase in fair value of financial instruments" in "Comprehensive income (loss)". The decrease in fair value from the effective hedge date to the year ended April 30, 2016 was $1,158 and was recorded in "Decrease in fair value of financial instruments" in "Comprehensive income (loss)". The Company believes there have been no material changes in the creditworthiness of the counterparty to this cap agreement and believes the risk of nonperformance by such party is minimal. See Note 18, "Accumulated Other Comprehensive (Loss) Income."

        We consider the interest rate cap to be a Level 2 fair value measurement for which market-based pricing inputs are observable. Generally, we obtain our Level 2 pricing inputs from our counterparties. Substantially all of

these assumptions are observable in the marketplace throughout the full term of the instrument, can be derived from observable data or are supported by observable levels at which transactions are executed in the marketplace.

        For derivatives that do not qualify or are not designated as hedging instruments for accounting purposes, changes in fair value are recorded in current period earnings (commonly referred to as the "mark-to-market" method). Prior to Predecessor 2014, the Company entered into an interest-rate swap agreement as a fixed-rate payor to mitigate interest-rate risk associated with floating interest rate borrowings under the ABL Facility on an initial notional amount of $35,000. Per the terms of the contract, the Predecessor received fixed interest of 0.69 percent in exchange for floating interest indexed to the one-month LIBOR rate. Changes in fair value resulted in a gain of $208 for Predecessor 2014. These gains and losses are recognized in the Consolidated Statements of Operations and Comprehensive Income (Loss), in "Other income, net". The interest rate swap was terminated in Predecessor 2014 with a penalty of $105 and interest of $16 and is recorded in "Other income, net" in the Consolidated Statements of Operations and Comprehensive Income (Loss). We consider the interest rate swap to be a Level 2 fair value measurement for which market-based pricing inputs are observable.

Insurance Liabilities

        The Company is self-insured for certain losses related to medical claims. The Company has deductible-based insurance policies for certain losses related to general liability, workers' compensation and automobile. The deductible amount is $250, $500 and $1,000 for general liability, workers' compensation and automobile, respectively. The Company has stop-loss coverage to limit the exposure arising from claims. The coverage consists of a primary layer and an excess layer. The primary layer of coverage is from $500 to $2,000 and the excess layer covers claims from $2,000 to $100,000. The expected ultimate cost for claims incurred as of the balance sheet date is not discounted and is recognized as a liability. Insurance losses for claims filed and claims incurred but not reported are accrued based upon estimates of the aggregate liability for uninsured claims using loss development factors and actuarial assumptions followed in the insurance industry and historical loss development experience.

        At April 30, 2016 and 2015, the aggregate liabilities for medical self-insurance were $3,342 and $2,468, respectively, and are recorded in "Other liabilities" within the Consolidated Balance Sheets. At April 30, 2016 and 2015, reserves for general liability, automobile and workers' compensation totaled approximately $12,213 and $36,808 respectively, and are recorded in "Other accrued expenses and current liabilities" and "Other liabilities" in the Consolidated Balance Sheets, the majority of the fiscal 2015 amount relates to an insured automobile claim, subject to a $500 deductible. During the year ended April 30, 2016, the claim was paid by our insurance carrier in the amount of approximately $26,300, subject to the deductible. At April 30, 2016 and 2015, recoveries for general liability, automobile and workers' compensation, totaled approximately $4,832 and $30,714, respectively and are recorded in "Prepaid expenses and other current assets" and "Other assets" in the Consolidated Balance Sheets.

Income Taxes

        Income taxes are accounted for in accordance with ASC 740 "Income Taxes," which requires the use of the asset and liability method. Deferred tax assets and liabilities are recognized based on the difference between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Inherent in the measurement of deferred balances are certain judgments and interpretations of existing tax law and published guidance as applicable to our operations.

(in thousands of dollars, except for share and per share data)

1. Basis of Presentation, Business and Summary of Significant Accounting Policies (Continued)

        We evaluate our deferred tax assets to determine if valuation allowances are required. In assessing the realizability of deferred tax assets, we consider both positive and negative evidence in determining whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The primary negative evidence considered includes the cumulative operating losses generated in prior periods. The primary positive evidence considered includes the reversal of deferred tax liabilities related to depreciation and amortization that would occur within the same jurisdiction and during the carry-forward period necessary to absorb the federal and state net operating losses and other deferred tax assets. The reversal of such liabilities would utilize the federal and state net operating losses and other deferred tax assets.

        We record amounts for uncertain tax positions that management believes are supportable, but are potentially subject to successful challenge by the applicable taxing authority. Consequently, changes in our assumptions and judgments could materially affect amounts recognized related to income tax uncertainties and may affect our results of operations or financial position. We believe our assumptions for estimates are reasonable, although actual results may have a positive or negative material impact on the balances of such tax positions. Historically, the variation of estimates to actual results is not significant and material variation is not expected in the future.

Credit and Economic Risk

        The Company's sources of liquidity have been and are expected to be cash from operating activities, available cash balances and the ABL Facility and the Term Loan Facilities. Financial instruments that potentially subject the Company to significant concentrations of credit risk consist principally of cash and cash equivalents and trade accounts and notes receivable. The Company assesses the credit standing of counterparties as considered necessary. The Company routinely assesses the financial strength of its customers and generally does not require collateral. Concentrations of credit risk with respect to trade accounts receivable are limited due to the large number of entities comprising the Company's customer base. The Company provides for doubtful accounts based on historical experience and when current conditions indicate that collection is doubtful. Accounts are written off when deemed uncollectible. In certain situations, the Company provides the customer with the right of product return; we have established a reserve for returns based on historic returns. The Company does not enter into financial instruments for trading or speculative purposes.

        The Company purchases a majority of its inventories from a select group of vendors. Without these vendors, the Company's ability to acquire inventory would be significantly impaired.

Fair Value of Financial Instruments

        Fair value is the price that would be received to sell an asset or paid to transfer a liability in the principal or most advantageous market in an orderly transaction between market participants on the measurement date. The carrying values of cash and cash equivalents, receivables, accounts payable, other current liabilities and accrued interest approximates fair value due to its short-term nature. Based on borrowing rates available to the Company for loans with similar terms, the carrying values of the ABL Facility and other debt approximates fair value. The Term Loan Facilities approximates fair value as the debt was issued on the Acquisition Date and interest rates have not changed significantly.

        Accounting guidance establishes a three-level hierarchy, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The valuation hierarchy

is based upon the transparency of inputs to the valuation of an asset or liability on the measurement date. The three levels are defined as follows:

Advertising Expense

        The cost of advertising is expensed as incurred and presented within "Selling, general and administrative" expenses in the Consolidated Statements of Operations and Comprehensive Income (Loss). The Company incurred approximately $2,043, $1,805, $114 and $1,282 in advertising costs in Successor 2016, Successor 2015, Successor 2014 and Predecessor 2014, respectively.

Equity-Based Compensation

        We account for stock options granted to employees and directors by recording compensation expense based on the award's fair value, estimated on the date of grant using the Black-Scholes option-pricing model. Equity-based compensation expense is recognized on a schedule that approximates the graded vesting of the awards.

        Determining the fair value of stock options under the Black-Scholes option-pricing model requires judgment, including estimating the fair value per share of our common stock, volatility, expected term of the awards, dividend yield and risk-free interest rate. The assumptions used in calculating the fair value of stock options represent our best estimates, based on management's judgment and subjective future expectations. These estimates involve inherent uncertainties. If any of the assumptions used in the model change significantly, share-based compensation recorded for future awards may differ materially from that recorded for awards granted previously.

        We estimate potential forfeitures of stock options and adjust share-based compensation expense accordingly. The estimate of forfeitures is adjusted over the requisite service period to the extent that actual forfeitures differ from prior estimates. We estimate forfeitures based upon our historical experience with employee turnover, and, on an annual basis, review the estimated forfeiture rate and make changes as factors affecting the forfeiture rate calculations and assumptions changes.

        We intend to use authorized and unissued shares to satisfy share award exercises, unless otherwise noted.

Stock Appreciation Rights, Deferred Compensation and Liabilities to Noncontrolling Interest Holders

        Certain subsidiaries have equity based compensation agreements with the subsidiary's employees and minority shareholders. These agreements are stock appreciation rights, deferred compensation agreements and liabilities to noncontrolling interest holders. Since these agreements are typically settled in cash or notes, and do not meet the criteria established by ASC 718, "Compensation—Stock Compensation" to be accounted for in "Stockholders' equity", they are accounted for as liability awards. See Note 14, "Stock Appreciation Rights, Deferred Compensation and Redeemable Noncontrolling Interests."

Treasury Stock

        In fiscal 2016, we repurchased 394,577 shares of our common stock at a cost of $5,827 in connection with our separation agreement with a former employee. We then reissued these shares for proceeds of $4,856. The difference between the cost of the treasury stock and the proceeds from its reissuance was accounted for, using the "cost" method, as an increase to "Accumulated deficit" of $971.

Net Earnings (Loss) Per Share

        Basic earnings (loss) per share is computed by dividing net income (loss) by the weighted-average number of outstanding common shares for the period. Diluted earnings (loss) per share reflects the potential dilution that could occur if instruments that may require the issuance of common shares in the future were settled and the underlying common shares were issued. Diluted earnings (loss) per share is computed by increasing the weighted-average number of outstanding common shares computed in basic earnings (loss) per share to include the dilutive effect of stock options and other equity-based instruments held by the Company's employees and directors during each period. In periods of net loss, the number of shares used to calculate diluted earnings per share is the same as basic earnings per share.

        Diluted net earnings (loss) per common share equals basic net earnings (loss) per common share for the Successor 2015 and Successor 2014 periods, as the effect of stock options and other equity-based instruments (collectively "stock-based compensation securities") are anti-dilutive because the Company incurred losses from continuing operations in those periods. During Successor 2015 and Successor 2014, stock-based compensation securities were excluded from the calculation of diluted earnings (loss) per share because their effect would have been anti-dilutive.

Recent Accounting Pronouncements

        Presentation of an unrecognized tax benefit—In July 2013, the FASB issued Accounting Standards Update ("ASU") No. 2013-11, "Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carry-forward, a Similar Tax Loss, or a Tax Credit Carry-forward Exists" ("ASU 2013-11"), which resolves diversity in practice on the financial statement presentation of an unrecognized tax benefit when a net operating loss carry-forward, a similar tax loss, or a tax credit carry-forward exists. An unrecognized tax benefit, or a portion of an unrecognized tax benefit, should be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carry-forward, a similar tax loss, or a tax credit carryforward, except in certain situations, as defined in ASU 2013-11. The amendments in ASU 2013-11 are effective prospectively for fiscal years, and interim periods within those years, beginning after December 15, 2013. The Company adopted ASU 2013-11 on May 1, 2014.

(in thousands of dollars, except for share and per share data)

1. Basis of Presentation, Business and Summary of Significant Accounting Policies (Continued)

adoption of this standard did not materially impact the Company's financial position, results of operations, or cash flows.

        Discontinued operations—In April 2014, the FASB issued ASU No. 2014-08, "Reporting Discontinued Operations and Disclosure of Disposals of Components of an Entity" ("ASU 2014-08"). The amended guidance requires that a disposal representing a strategic shift that has (or will have) a major effect on an entity's financial results or a business activity classified as held for sale should be reported as discontinued operations. The amendments also expand the disclosure requirements for discontinued operations and add new disclosures for individually significant dispositions that do not qualify as discontinued operations. The amendments are effective prospectively for fiscal years, and interim reporting periods within those years, beginning on or after December 15, 2014 (early adoption is permitted only for disposals that have not been previously reported). The impact on the Company of adopting ASU 2014-08 will depend on the nature and size of future disposals, if any, of a component of the Company after the effective date. The Company has elected to early adopt ASU2014-08 effective May 1, 2014. As a result of the adoption of this standard, the classification of a disposal made in fiscal 2015 that did not represent a strategic shift in the Company's direction or have a major impact on the Company's financial position or results of operations was not reported as a discontinued operation.

        Revenue recognition—In May 2014, the FASB issued ASU No. 2014-09, "Revenue from Contracts with Customers" ("ASU 2014-09"). The amended guidance outlines a single comprehensive revenue model for entities to use in accounting for revenue arising from contracts with customers. The guidance supersedes most current revenue recognition guidance, including industry-specific guidance. The core principle of the revenue model is that "an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services." Entities have the option of using either a full retrospective or modified approach to adopt the guidance. ASU 2014-09 is effective for fiscal years, and interim reporting periods within those years, beginning after December 15, 2017 (early adoption is not permitted). The Company is currently evaluating the impact of adopting ASU 2014-09.

        Going Concern—In August 2014 the FASB issued ASU 2014-15, "Disclosure of Uncertainties about an Entity's Ability to Continue as a Going Concern", which requires management to evaluate whether there are conditions or events that raise substantial doubt about an organization's ability to continue as a going concern and to provide related footnote disclosures. ASU 2014-15 is effective for interim and annual reporting periods beginning after December 15, 2016. Early adoption is permitted. The Company is currently evaluating the impact the adoption of this ASU will have on its Consolidated Financial Statements.

        Debt Issuance Costs—In April 2015, the FASB issued ASU 2015-03, "Simplifying the Presentation of Debt Issuance Costs," which changes the presentation of debt issuance costs in financial statements. Under the ASU, an entity presents such costs in the balance sheet as a direct deduction from the related debt liability rather than as an asset. Amortization of the costs is reported as interest expense. The guidance is effective prospectively for fiscal years, and interim reporting periods within those years, beginning on or after December 15, 2015. Early adoption is permitted and upon adoption, the guidance must be applied retroactively to all periods presented in the financial statements. Management has elected early adoption of the standard and retroactively applied it all periods presented in the accompanying Consolidated Financial Statements.

1. Basis of Presentation, Business and Summary of Significant Accounting Policies (Continued)

        Business Combinations—In September 2015, the FASB issued ASU No. 2015-16, "Simplifying the accounting for measurement-period adjustments" ("ASU 2015-16"). The amended guidance requires that an acquirer recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. The amendments are effective prospectively for the fiscal years, and interim reporting periods within those years, beginning on or after December 15, 2015 (early adoption were permitted only for financial statements that have not been issued). Management has early adopted the standard. The adoption of this standard did not materially impact our financial position, results of operations, or cash flows.

        Deferred Taxes—In November 2015, the FASB issued ASU No. 2015-17, "Balance Sheet Classification of Deferred Taxes ("ASU 2015-17"). This amendment changes how deferred taxes are recognized by eliminating the requirement of presenting deferred tax liabilities and assets as current and noncurrent on the balance sheet. Instead, the requirement will be to classify all deferred tax liabilities and assets as noncurrent. ASU 2015 17 is effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period, with earlier adoption permitted. ASU 2015-17 can be adopted either prospectively or retrospectively to all periods presented. The Company is in the process of determining the method of adoption and assessing the impact ASU 2015-17 will have on its Consolidated Financial Statements.

        Leases—In February 2016, the FASB issued ASU No. 2016-02, "Leases" ("ASU 2016-02"). The new standard establishes a right-of-use (ROU) model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with such classification affecting the pattern of expense recognition in the statement of operations. The new standard is effective for the Company's fiscal year beginning May 1, 2019, including interim reporting periods within that fiscal year. A modified transition approach is required for lessees for capital and operating leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. While the Company is still evaluating the impact of its pending adoption of the new standard on its Consolidated Financial Statements, the Company expects that upon adoption it will recognize ROU assets and liabilities that could be material.

        Equity Compensation—In March 2016, the FASB issued ASU 2016-09, "Compensation—Stock Compensation (Topic 718): Improvements to Employee ShareBased Payment Accounting" ("ASU 2016-09"). Several aspects of the accounting for share-based payment award transactions are simplified, including: (a) income tax consequences; (b) classification of awards as either equity or liabilities; (c) forfeitures; and (d) classification on the statement of cash flows. The amendments are effective for public companies for annual periods beginning after December 15, 2016, and interim periods within those annual periods. Early adoption is permitted for any interim or annual period. The Company is currently in the process of evaluating the impact of the adoption on its Consolidated Financial Statements.

2. Acquisition of Gypsum Management and Supply, Inc.

        On the Acquisition Date, the Company acquired all of the outstanding common shares of Gypsum Management and Supply, Inc. (Predecessor) for a purchase price of $821,045. The Acquisition was accounted for using the acquisition method of accounting, in accordance with ASC 805, "Business Combinations," which requires that assets acquired and liabilities assumed be recognized at their fair values as of the acquisition date.

consideration transferred was funded with approximately $224,000 cash from AEA and co-investors, approximately $503,000 from the Term Loan Facilities and $94,279 of interests that were converted from ownership interests of certain members of Predecessor management and noncontrolling interest holders. The table below summarizes the consideration transferred to acquire Gypsum Management and Supply, Inc. which includes cash and certain noncontrolling interests in subsidiaries of Gypsum Management and Supply, Inc.:

Consideration Transferred

        The identified assets acquired and liabilities assumed based on their estimated fair values at the Acquisition Date are as follows:

        The Company acquired intangible assets of $216,182. See Note 6, "Goodwill and Intangible Assets," for the summary of the fair value estimates of the identifiable intangible assets and their useful lives.

        The $327,136 of goodwill represents the cost in excess of the fair value of net assets acquired and is attributable to the entrepreneurial culture and leading market position of Predecessor and the expected significant growth of the business. The fair value was determined based on market participant assumptions using common valuation techniques. The goodwill is not deductible for income tax purposes.

2. Acquisition of Gypsum Management and Supply, Inc. (Continued)

        The Company incurred Acquisition-related costs of $68,801, of which $837, $16,155 and $51,809 were incurred in Successor 2015, Successor 2014 and Predecessor 2014, respectively, and which are included in "Selling, general and administrative" expenses in the Consolidated Statements of Operations and Comprehensive Income (Loss).

        As discussed in Note 1, certain prior year amounts were revised to properly reflect deferred income tax liabilities and the related goodwill established during purchase accounting. As a result of these revisions, "Deferred income taxes, net" and "Goodwill" on the Consolidated Balance Sheet increased by $6,400 as of April 30, 2015.

3. Business Acquisitions

        The Company operates in a highly fragmented industry. A key component of the Company's strategy is growth through acquisition that expands its geographic coverage, provides complementary lines of business and increases its market share.

        The Company has accounted for all business combinations using the purchase method, in accordance with ASC 805, to record a new cost basis for the assets acquired and liabilities assumed. The Company recorded, based on preliminary purchase price allocations, intangible assets representing client relationships, tradenames, and excess of purchase price over the estimated fair values of the net assets acquired as "Goodwill" in the accompanying Consolidated Financial Statements. The goodwill is attributable to synergies achieved through the streamlining of operations combined with improved margins attainable through increased market presence. The results of operations are reflected in the Consolidated Financial Statements of the Company from the date of acquisition.

(a)   2016 Acquisitions

        In fiscal 2016, the Company completed the following acquisitions, with an aggregate purchase price of $117,178, comprised of $114,554 net of cash consideration and $2,624 of contingent consideration, subject to finalization of working capital settlement amounts. In connection with these acquisitions, the Company incurred transaction costs of $2,056 in the year ended April 30, 2016. These costs are included in "Selling, general and administrative" expenses in the Company's accompanying Consolidated Statements of Operations and Comprehensive Income (Loss). The purpose of these acquisitions was to expand the geographical coverage of the Company and grow the business. These acquisitions increased net sales by $72,277 for the year ended April 30, 2016.

        The preliminary allocation of consideration for these acquisitions is summarized as follows:

        Goodwill of $13,736 and other intangible assets of $26,335 are expected to be deductible for U.S. federal income tax purposes. Goodwill of $25,097 and other intangibles of $17,240 are nondeductible for U.S. federal income tax purposes. The Company believes that information gathered to date provides a reasonable basis for estimating the fair values of assets acquired and liabilities assumed but the Company is waiting for additional information necessary to finalize those fair values. Thus, the provisional measurements of fair value set forth above are preliminary. Such changes are not expected to be significant. The Company expects to complete the purchase price allocation as soon as practicable but no later than one year from the applicable acquisition date. The pro forma impact of these acquisitions is not presented as it is not considered material to our Consolidated Financial Statements.

(b)   2015 Acquisitions

        In fiscal 2015, the Company completed the following acquisitions, with an aggregate purchase price of $72,208, comprised of $69,168 net of cash consideration and $3,040 of contingent consideration. In connection with these acquisitions, the Company incurred transaction costs of $12 and $945 in the year ended April 30, 2016 and 2015, respectively. These costs are included in "Selling, general and administrative" expenses in the Company's accompanying Consolidated Statements of Operations and Comprehensive Income (Loss). The purpose of these acquisitions was to expand the geographical coverage of the Company and grow the business. These acquisitions increased net sales by $44,380 for the year ended April 30, 2015.

8. Long-Term Debt

        "Long-term debt" at April 30, 2016 and 2015 consists of the following:

Acquisition Debt (Successor)

        On April 1, 2014, the Company's wholly-owned subsidiaries, GYP Holdings II Corp., as parent guarantor (in such capacity, "Holdings"), and GYP Holdings III Corp., as borrower (in such capacity, the "Borrower" and, together with Holdings and the Subsidiary Guarantors (as defined below), the "Loan Parties"), entered into a senior secured first lien term loan facility (the "First Lien Facility") and a senior secured second lien term loan facility (the "Second Lien Facility" and, together with the First Lien Facility, the "Term Loan Facilities") in the aggregate amount of $550,000 to acquire Gypsum Management and Supply, Inc. The proceeds from the Term Loan Facilities were used to (i) repay all amounts outstanding under the 2010 Credit Facility in the amount of $86,120, (ii) pay the acquisition purchase price and (iii) pay related fees and expenses.

        The Term Loan Facility consists of a First Lien Term Loan and a Second Lien Term Loan (respectively, the "First Term Loan" and "Second Term Loan" and collectively, the "Term Loans"). The First Term Loan was issued in an original aggregate principal amount of $388,050 (net of $1,950 of original issue discount). The Second Term Loan was issued in an original aggregate principal amount of $158,400 (net of $1,600 of original issue discount). At April 30, 2016, the borrowing interest rate for the First Term Loan and Second Term Loan was 4.75% and 7.75%, respectively. Accrued interest, presented within "Other accrued expenses and current liabilities" in our Consolidated Balance Sheets, was $246 and $1,119 at April 30, 2016 and 2015, respectively. Cash paid for interest was $32,130, $30,251 and $2,491 for Successor 2016, Successor 2015 and Successor 2014, respectively. The First Lien Facility permits the Borrower to add one or more incremental term loans up to a fixed amount of $100,000 (shared with the Second Term Loan) plus a certain amount depending on a secured first lien leverage ratio test

included in the First Lien Facility. The Second Lien Facility permits the Borrower to add one or more incremental term loans up to a fixed amount of $100,000 (shared with the First Lien Facility) plus a certain amount depending on a secured leverage ratio test included in the Second Lien Facility. The First Term Loan bears interest at LIBOR (subject to a floor of 1.00%) plus a borrowing margin of 3.75%. The Second Term Loan bears interest at LIBOR (subject to a floor of 1.00%) plus a borrowing margin of 6.75%. The First Term Loan amortizes in nominal quarterly installments of $975, or 0.25% of the original aggregate principal amount of the First Term Loan and matures on April 1, 2021. The Second Term Loan has no amortization and matures on April 1, 2022. Provided that the individual affected lenders agree accordingly, the maturities of the Term Loans may, upon the Borrower's request and without the consent of any other lender, be extended.

        On June 1, 2016, we repaid the entire outstanding principal balance under the Second Lien Term Loan, see Note 23, "Subsequent Events."

Asset Based Lending Facility (Successor)

        The Asset Based Lending Credit Facility (the "ABL Facility"), entered into on April 1, 2014, provides for revolving loans and the issuance of letters of credit up to a maximum aggregate principal amount of $200,000 (subject to availability under a borrowing base). GYP Holdings III Corp. is the lead borrower (in such capacity, the "Lead Borrower"). Extensions of credit under the ABL Facility will be limited by a borrowing base calculated periodically based on specified percentages of the value of eligible inventory and eligible accounts receivable, subject to certain reserves and other adjustments. As of April 30, 2016, the Company had $187,185 of available borrowings and $101,910 in short-term swing line borrowings and eurodollar loans outstanding under the ABL Facility as presented within "Revolving credit facility" under "Current Liabilities" on the Consolidated Balance Sheets. As of April 30, 2015, the Company had $171,688 of available borrowings and $16,950 in short-term swing line borrowings and eurodollar loans outstanding under the ABL Facility as presented within "Revolving credit facility" under "Current Liabilities" on the Consolidated Balance Sheets. As of April 30, 2016 and 2015, there was $422 and $280 accrued interest payable, respectively on the facility. In Successor 2016, Successor 2015 and Successor 2014, we paid interest and other fees on the facility of $1,900, $941 and $76, respectively. The ABL Facility also permits the Company to request increases in the amount of the revolving, swing line and letter of credit facilities up to an aggregate maximum amount of $300,000 for the total commitments under the ABL Facility (including all incremental commitments).

        As of April 30, 2016 and 2015, the Company reflected $2,544 and $2,949, respectively, of deferred financing costs related to the ABL Facility in "other assets" on its Consolidated Balance Sheets.

        In fiscal 2016, we amended our ABL Facility to exercise the $100,000 accordion feature of the ABL Facility which increased the aggregate revolving commitments from $200,000 to $300,000 and increased the sublimit for same day swing line borrowings from $20,000 to $30,000. The other terms of the ABL Facility remain unchanged.

        At the Company's option, the interest rates applicable to the loans under the ABL Facility are based at LIBOR or base rate plus, in each case, an applicable margin. The margins applicable for each elected interest rate are subject to a pricing grid, as defined in the ABL Facility agreement, based on average daily availability for the most recent fiscal quarter. The applicable rate of interest for fiscal 2016 and fiscal 2015 was 2.97% and 3.75%, respectively. The ABL Facility also contains an unused commitment fee subject to utilization, as included in the ABL Facility agreement.

8. Long-Term Debt (Continued)

        The ABL Facility will mature on April 1, 2019 unless the individual affected lenders agree to extend the maturity of their respective loans under the ABL Facility upon the Company's request and without the consent of any other lender. The ABL Facility contains a cross default provision with the Term Loan Facility.

Collateral under the ABL Facility and Term Loan Facilities

        The ABL Facility is collateralized by (a) first priority perfected liens on the following assets of the Loan Parties: (i) accounts receivable; (ii) inventory; (iii) deposit accounts; (iv) cash and cash equivalents; (v) tax refunds and tax payments; (vi) chattel paper and (vii) documents, instruments, general intangibles, securities accounts, books and records, proceeds and supporting obligations related to each of the foregoing, subject to certain exceptions (collectively, "ABL Priority Collateral") and (b) third priority perfected liens on the remaining assets of the Loan Parties not constituting ABL Priority Collateral, subject to customary exceptions (collectively, "Term Priority Collateral").

        The First Lien Facility and the Second Lien Facility are collateralized by (a) first priority liens and second priority liens, respectively, on the Term Priority Collateral and (b) second priority liens and third priority liens, respectively, on the ABL Priority Collateral, subject to customary exceptions.

Prepayments under the ABL Facility and Term Loan Facilities

        The Term Loans may be prepaid at any time without penalty, except that the Second Term Loan is subject to a 1% prepayment premium on voluntary prepayments and certain mandatory prepayments made prior to April 1, 2016. Under certain circumstances and subject to certain exceptions, the Term Loan Facilities will be subject to mandatory prepayments in the amount equal to:

•

100% of the net proceeds of certain asset sales and issuances or incurrences of nonpermitted indebtedness; and



•

50% of annual excess cash flow for any fiscal year, such percentage to decrease to 25% or 0% depending on the attainment of certain total leverage ratio targets.

        As of April 30, 2016 there was no prepayment required related to excess cash flow.

        The ABL Facility may be prepaid at the Company's option at any time without premium or penalty and will be subject to mandatory prepayment if the outstanding ABL Facility exceeds the lesser of the (i) borrowing base and (ii) the aggregate amount of commitments. Mandatory prepayments do not result in a permanent reduction of the lenders' commitments under the ABL Facility.

Guarantees

        Holdings guarantees the payment obligations under the ABL Facility and the Term Loan Facilities. Certain of Holdings' subsidiaries (i) guarantee the payment obligations under the Term Loan Facilities (in such capacity, the "Subsidiary Guarantors") and (ii) are co-borrowers under the ABL Facility.

Covenants under the ABL Facility and Term Loan Facilities

        The ABL Facility contains certain affirmative covenants, including financial and other reporting requirements. The Company is in compliance with all such covenants at April 30, 2016.

        The Term Loan Facilities contain a number of covenants that limit the ability of the Borrower and its restricted subsidiaries, as described in the Term Loan Facilities, to: incur more indebtedness; pay dividends, redeem stock or make other distributions; make investments; create restrictions on the ability of the Company's restricted subsidiaries to pay dividends to the Company or make other intercompany transfers; create liens securing indebtedness; transfer or sell assets; merge or consolidate; enter into certain transactions with the Company's affiliates; and prepay or amend the terms of certain indebtedness. The Company is in compliance with all restrictive covenants at April 30, 2016.

Events of Default under the ABL Facility and Term Loan Facilities

        The ABL Facility and Term Loan Facilities also provide for customary events of default, including non-payment of principal, interest or fees, violation of covenants, material inaccuracy of representations or warranties, specified cross default to other material indebtedness, certain bankruptcy events, certain ERISA events, material invalidity of guarantees or security interest, material judgments and changes of control.

Asset Based Lending Facility (Predecessor)

Installment Notes

        The installment notes as of April 30, 2016 represent notes for subsidiary stock repurchases from shareholders, notes for the payout of stock appreciation rights and a note to the seller of an acquired company. The installment notes as of April 30, 2015 represent notes for subsidiary stock repurchases from shareholders and a note for the payout of stock appreciation rights. See Note 14, "Stock Appreciation Rights, Deferred Compensation and Redeemable Noncontrolling Interests."

9. Predecessor Mandatorily Redeemable Common Shares

        Prior to the Acquisition, our founders owned one hundred percent of the outstanding shares of Gypsum Management and Supply, Inc. (Predecessor). These shares had certain redemption features which provided that upon the death or disability of the shareholder or termination of his employment, Predecessor would be required to purchase these shares at their then current fair values. Pursuant to this provision, these shares were deemed to be mandatorily redeemable and, as such, were required to be reflected as a liability at their estimated fair values at the end of any reporting period. Changes in fair value are reflected as "Change in fair value of mandatorily redeemable common shares" on our Consolidated Statements of Operations and Comprehensive Income (Loss). Fair value was estimated based on common valuation techniques. On April 1, 2014, all outstanding shares were acquired or converted into the equity of GMS Inc. at the Acquisition Date.

        The following table sets forth a roll forward of the Level 3 fair values of the Predecessor's mandatorily redeemable common shares. These techniques were based on a combination of a discounted cash flow analysis, which was determined using management's projections, and a market comparable method.

10. Retirement Plan

        The Company maintains a defined contribution retirement plan for its employees. Participants are allowed to choose from a 401(k) of mutual funds in order to designate how both employer and employee contributions are invested. Under the plan, the Company matches 50% of each employee's contributions on the first 4% of the employee's compensation contributed. The Company contributed $1,743, $1,120, $86, and $891 in Successor 2016, Successor 2015, Successor 2014, and Predecessor 2014, respectively.

11. Income Taxes

        As discussed in Note 1, during the preparation of the Annual Report on Form 10-K for the year ended April 30, 2016, the Company determined that the statutory tax rate used to value deferred tax liabilities related to certain assets purchased in the Acquisition as of April 1, 2014 needed to be adjusted. This misstatement resulted in an understatement of the net deferred tax liability and goodwill, and in 2015, an overstatement of tax expense and a resultant understatement of net income (loss) for the year ended April 30, 2015. The impact of this revision for periods presented are reflected in the disclosure that follows.

        Income tax expense (benefit) for Successor 2016, Successor 2015, Successor 2014 and Predecessor 2014 consists of the following:

        Total income tax expense (benefit) from continuing operations differed from the amount computed by applying the federal statutory rate of 35% for Successor 2016, Successor 2015, Successor 2014 and Predecessor 2014 due to the following:

        Income taxes for financial reporting purposes differ from the amount computed by applying the statutory federal rate primarily due to the effect of state income taxes, net of federal benefit, permanent differences, the release of valuation allowance related to certain state net operating losses, and non-deductible non-cash debt related charges.

11. Income Taxes (Continued)

        The tax effects of temporary differences, which give rise to deferred income taxes as of April 30, 2016 and 2015 are as follows:

        In Successor 2016, Successor 2015, Successor 2014 and Predecessor 2014, the Company generated certain state net operating loss carry-forwards which are available for use against taxable income in each respective state.

(in thousands of dollars, except for share and per share data)

11. Income Taxes (Continued)

The Company had state net operating losses available for carry-forward of $20,228 and $23,596 in Successor 2016 and Successor 2015, respectively, which expire through the fiscal year ending in 2036.

        Deferred tax assets and liabilities are computed by applying the federal and state income tax rates in effect to the gross amounts of temporary differences and other tax attributes, such as net operating loss carry-forwards. In assessing if the deferred tax assets will be realized, the Company considers whether it is more likely than not that some or all of these deferred tax assets will be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the period in which these deductible temporary differences reverse. As of April 30, 2016, except as noted in the following paragraph, the Company believes that it is more likely than not that all of its deferred tax assets relating to separate company state return filings will be realized. The tax credits, carryforwards and net operating losses expire from 2017 to 2036.

        Management makes an assessment to determine if its deferred tax assets are more likely than not to be realized. Valuation allowances are established in the event that management believes that it is more likely than not the related tax benefits will not be realized. The valuation allowance as of April 30, 2016 and 2015 of $83 and $143, respectively, primarily relates to state net operating loss carry forwards. During fiscal 2016 and 2015, the valuation allowance decreased by $60 and $1,134, respectively, which is primarily due to increased profitability. During the month ended April 30, 2014 the valuation allowance increased by $100 and during the eleven months ended March 31, 2014, the valuation allowance decreased by $279.

        The Company recognizes the effect of income tax positions only if those positions are more likely than not to be sustained. The Company's policy for recording penalties and interest related to uncertain tax positions is to record these amounts in "Selling, general and administrative" expense.

        At April 30, 2016, Successor 2016, Successor 2015, Successor 2014 and Predecessor 2014 remain subject to examination by the U.S. Internal Revenue Service. In states in which the Company conducts business, the statute of limitation periods for examination generally vary from three to four years. Certain years from which net operating losses are still being carried forward remain subject to examination by the taxing authorities. The Company regularly assesses the potential outcomes of future examinations to ensure the Company's provision for income taxes is sufficient. The Company recognizes liabilities based on estimates of whether additional taxes will be due and believes that no reserves are necessary as of April 30, 2016 and 2015.

12. Stockholders' Equity

Successor Stockholders' Equity

        The Company authorized 500,000,000 shares of $0.01 par value common stock of which 32,892,905 and 32,757,905 were outstanding at April 30, 2016 and 2015, respectively.

        The Company authorized 50,000,000 shares of $0.01 par value preferred stock of which there were no shares outstanding at April 30, 2016 and 2015.

        On May 13, 2016, we amended and restated our certificate of incorporation, see Note 23, "Subsequent Events."

13. Equity-Based Compensation

General

        The Company has a 2014 GYP Holdings I Corp. Stock Option Plan, (the "Plan") that provides for granting of stock options and other equity awards. The Plan authorizes 3,591,422 shares of common stock for issuance. The stock options vest over a four year period and have a 10-year term. The plan is designed to motivate and retain individuals who are responsible for the attainment of our primary long-term performance goals. The plan provides a means whereby our employees and directors develop a sense of ownership and personal involvement in our development and financial success and encourage them to devote their best efforts to our business. The Company accounts for share-based awards in accordance with ASC 718. ASC 718 requires measurement of compensation cost for all share-based awards at fair value on the grant date (or measurement date if different) and recognition of compensation expense, net of estimated forfeitures, over the requisite service period for awards expected to vest.

Stock Option Awards

        We utilize the Black-Scholes option-pricing model to estimate the grant-date fair value of all stock options. The Black-Scholes option-pricing model requires the use of weighted average assumptions for estimated expected volatility, estimated expected term of stock options, risk-free rate, estimated expected dividend yield, and the fair value of the underlying common stock at the date of grant. Prior to our initial public offering discussed in Note 23, "Subsequent Events," we did not have sufficient history to estimate the expected volatility of our common stock price, expected volatility has been based on the average volatility of peer public entities that are similar in size and industry. We estimate the expected term of all stock options based on previous history of exercises. The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of grant for the expected term of the stock option. The expected dividend yield is 0% as we have not declared any common stock dividends to date and do not expect to declare common stock dividends in the near future. The fair value of the underlying common stock at the date of grant was determined based on a valuation of our common stock. We estimate forfeitures based on our historical analysis of actual stock option forfeitures and employee turnover. Actual forfeitures are recorded when incurred and estimated forfeitures are reviewed and adjusted at least annually. The weighted average assumptions used in the Black-Scholes option-pricing model for the year ended April 30, 2015 are set forth below:

        In fiscal 2015, the Company accounted for 2,824,050 stock option awards issued to employees that vest based on service only. The weighted average grant date fair value of each stock option was $4.73 and the aggregate fair value of options outstanding was $13,361 and the aggregate fair value of options vested as of April 30, 2015 was $2,228. All of these awards vest over a four-year period. Additionally, all these options could vest earlier in the event of a change in control, merger or other acquisition. This expense is recorded on an accelerated basis over the requisite service period of each separate vesting tranche. Share-based compensation expense related to stock

option awards was $2,699 and $6,455 for the year ended April 30, 2016 and 2015, respectively, and was included as a component of "Selling, general and administrative" expenses in our Consolidated Statements of Operations and Comprehensive Income (Loss). The Company also recognized related income tax benefits of $2,593. At April 30, 2016 and 2015, the unrecognized compensation expense related to stock option awards was $2,344 and $5,570, respectively, with a remaining weighted average life of 2.0 years and 3.1 years, respectively.

        The Company did not issue any stock option awards in fiscal 2016.

        A summary of stock option activity for the year ended April 30, 2016 and 2015 follows:

        Aggregate intrinsic value represents the fair value of the underlying common stock at the date of grant, which was determined based on the per share valuation of our common stock in excess of the weighted average exercise price multiplied by the number of options outstanding or exercisable. Options expected to vest are unvested shares net of expected forfeitures.

        As of April 30, 2016, the aggregate fair value of options outstanding was $8,792 and the aggregate fair value of options vested was $5,286. The total intrinsic value of stock option awards exercised was approximately $8,892 during the fiscal year ended April 30, 2016.

        On May 13, 2016, we amended and restated our certificate of incorporation, see Note 23, "Subsequent Events."

Subsidiaries' Stock Option Plans

        Certain subsidiaries of the Company granted stock options to certain employees prior to Predecessor 2014 under various plans (the "Subsidiary Plans"). The options were valued based on the underlying common stock changes from year to year and compensation expense was recognized over the vesting period. Compensation expense recognized in Successor 2014 and Predecessor 2014, was $1 and $27, respectively. All stock options awarded under the Subsidiary Plans were exercised or expired prior to April 30, 2015.

(in thousands of dollars, except for share and per share data)

14. Stock Appreciation Rights, Deferred Compensation and Redeemable Noncontrolling Interests

        Certain subsidiaries have equity based compensation arrangements with certain of the subsidiary's employees and minority shareholders. These arrangements are stock appreciation rights, deferred compensation agreements and liabilities to noncontrolling interest holders. Since these arrangements are typically settled in cash or notes, and do not meet the criteria established by ASC 718 to be accounted for in "Stockholders' equity", they are accounted for as liability awards. As a result of the transition guidance stated within ASC 718, we have recorded these liability awards at fair value as of April 30, 2016.

        Stock appreciation rights—Certain subsidiaries have granted stock appreciation rights to certain employees under which payments are dependent on the appreciation in the book value per share, adjusted for certain provisions, of the applicable subsidiary. Settlements of the awards can be made in a combination of cash or installment notes, generally paid over four years, upon a triggering event. Vesting periods vary by grant date and range from fiscal 2017 to fiscal 2018. Current liabilities related to these plans of $808 and $1,050 were recorded as components of "Accrued compensation and employee benefits" at April 30, 2016 and 2015, respectively. Long-term liabilities related to these plans of $19,725 and $7,019 were recorded as components of "Other liabilities" at April 30, 2016 and 2015, respectively. Below is a summary of changes to the liability:

        The Company recorded stock appreciation rights expense of $1,988, $2,268, $80 and $1,288 in Successor 2016, Successor 2015, Successor 2014 and Predecessor 2014, respectively, and is included as a component of "Selling, general and administrative" expenses in our Consolidated Statements of Operations and Comprehensive Income (Loss). In Successor 2016, the Company recorded $11,245 as an increase to "Accumlated deficit" in our Consolidated Balance Sheets as a result of the change in value due to the transition guidance in ASC 718.

        Deferred compensation—Subsidiaries' shareholders have entered into other deferred compensation agreements that granted the shareholders a payment based on a percentage in excess of book value, adjusted for certain provisions, upon an occurrence as defined in the related agreements, which are called "Buy Sell" agreements. Current liabilities related to these plans of $0 and $11 were recorded as components of "Accrued compensation and employee benefits" at April 30, 2016 and 2015, respectively. The remaining liabilities related to these plans of $3,270 and $3,479 were recorded as components of "Other liabilities" at April 30, 2016 and 2015, respectively.

14. Stock Appreciation Rights, Deferred Compensation and Redeemable Noncontrolling Interests (Continued)

These instruments are redeemed in cash or installment notes, generally paid in annual installments generally over the five years following termination of employment. Below is a summary of changes to the liability:

        The Company recorded redeemable noncontrolling interests expense of $45, $289, $31 and $626 in Successor 2016, Successor 2015, Successor 2014 and Predecessor 2014, respectively, and is included as a component of "Selling, general and administrative" expenses in our Consolidated Statements of Operations and Comprehensive Income (Loss). In Successor 2016, the Company recorded $234 as a decrease to "Accumlated deficit" in our Consolidated Balance Sheets as a result of the change in value due to the transition guidance in ASC 718.

        Liabilities to noncontrolling interest holders—As described in Note 1, "Basis of Presentation, Business and Summary of Significant Accounting Policies," noncontrolling interests were issued to certain employees of the subsidiaries. All of the noncontrolling interest awards are subject to mandatory redemption on termination of employment for any reason. These instruments are redeemed in cash or installment notes, generally paid in annual installments generally over the five years following termination of employment.

        Liabilities related to these agreements are classified as share based liability awards and are measured at intrinsic value under ASC 718. Intrinsic value is determined to be the stated redemption value of the shares. Under the terms of the employee agreements, the redemption value is determined based on the book value of the subsidiary, as adjusted for certain items. As of April 30, 2016, the total fair value of these liabilities was $26,585. Amounts expected to be paid in the next year are included in "Accrued compensation and employee benefits" at April 30, 2016 in the amount of $1,338. Long term liabilities of $25,247 related to this plan were recorded to "Liabilities to noncontrolling interest holders, less current portion" at April 30, 2016. Below is a summary of changes to the liability:

        The Company recorded redeemable noncontrolling interests expense of $881, $1,570, $40 and $2,331 in Successor 2016, Successor 2015, Successor 2014 and Predecessor 2014, respectively, and is included as a component of "Selling, general and administrative" expenses in our Consolidated Statements of Operations and

Comprehensive Income (Loss). In Successor 2016, the Company recorded $3,706 as a decrease to "Accumlated deficit" in our Consolidated Balance Sheets as a result of the change in value due to the transition guidance in ASC 718.

        In connection with the Acquisition, noncontrolling interest holders had the option to convert their interests in the subsidiaries into the Company. Noncontrolling interests of $32,545 were converted into the Company's common shares at the date of the Acquisition.

        Upon the termination of employment or other triggering events including death or disability of the noncontrolling stockholders in the Company's subsidiaries, we are obligated to purchase, or redeem, the noncontrolling interests at either an agreed upon price or a formula value provided in the stockholder agreements. This formula value is typically based on the book value per share of the subsidiary's equity, including certain adjustments.

15. Transactions With Related Parties

        The Company leases office and warehouse facilities from partnerships owned by certain stockholders of GMS Inc. and its subsidiaries. At April 30, 2016, these leases had expiration dates through fiscal 2021. Rent expense related to these leases included in the accompanying Consolidated Financial Statements approximated $628, $903, $77 and $854 for Successor 2016, Successor 2015, Successor 2014 and Predecessor 2014, respectively, and are recorded in "Selling, general and administrative" expenses. At April 30, 2016, future minimum payments under the terms of the leases aggregated to $1,849.

        The Company purchases inventories from its former subsidiary, Southern Wall Products, Inc. ("SWP"), on a continuing basis. Certain stockholders of the Company are stockholders of SWP, which was spun-off from Gypsum Management and Supply, Inc. on August 31, 2012. The Company purchased inventory from SWP for distribution in the amount of $12,795, $11,926, $1,037 and $10,033 in Successor 2016, Successor 2015, Successor 2014 and Predecessor 2014, respectively. Amounts due to SWP for purchases of inventory for distribution as of April 30, 2016 and 2015 were $1,097 and $943, respectively, and are included in "Accounts payable". Purchases between Gypsum Management and Supply, Inc. and SWP prior to the spin-off were accounted for as intercompany transactions and eliminated in consolidation.

        The Company has a management agreement in place with AEA Investors LP. The agreement requires the Company to pay AEA an annual management fee of $2,250 per year following the Acquisition for advisory and consulting services. The fee is payable in quarterly installments of $563 in advance of the upcoming calendar quarter on the first day, and is included in "Selling, general and administrative" expenses in the Consolidated Statements of Operations and Comprehensive Income (Loss).

        On June 1, 2016, we terminated our management agreement with AEA Investors LP in connection with our initial public offering, see Note 23, "Subsequent Events."

16. Commitments and Contingencies

Lease Commitments

        The Company is obligated under certain capital leases covering our fleet of vehicles as well as one facility. The fleet vehicle leases have terms ranging from one to five years and the facility lease has a term of 11 years. The carrying value of property and equipment under capital leases was $10,928 and $8,555 at April 30, 2016 and 2015, respectively, net of accumulated depreciation of $6,696 and $5,005, respectively. Amortization of assets held under capital leases is $4,685, $4,320, $309 and $3,398 in Successor 2016, Successor 2015, Successor 2014 and Predecessor 2014, respectively, and is included with depreciation expense on the Consolidated Statements of Operations and Comprehensive Income (Loss).

        The Company also has certain noncancelable operating lease agreements, primarily office and warehouse facilities and equipment. These leases generally contain renewal options for periods ranging from one to five years. Rent expense for operating leases, which may have escalating rents over the terms of the leases, is recorded on a straight-line basis over the minimum lease terms. Rent expense under operating leases, including amounts paid to affiliated partnerships, approximated $41,733, $29,910, $1,458 and $19,878 for Successor 2016, Successor 2015, Successor 2014 and Predecessor 2014, respectively. As existing leases expire, the Company anticipates such leases will be renewed or replaced with other leases that are substantially similar in terms and rental amounts which are consistent with market rates at the time of renewal.

        At April 30, 2016, the approximate amounts of the annual future minimum lease payments under noncancelable operating leases, including amounts payable to affiliated partnerships, and future maturities of capital lease obligations are as follows:

Litigation, Claims and Assessment

        The Company is a defendant in various lawsuits and administrative actions associated with personal injuries, claims of former employees, and other events arising in the normal course of business. As discussed in Note 1, "—Insurance Liabilities", the Company records liabilities for these claims, and assets for amounts recoverable from the insurer, for these claims covered by insurance.

17. Segments

        The Company applies the provisions of ASC Topic 280, "Segment Reporting." ASC 280, which is based on a management approach to segment reporting, establishes requirements to report selected segment information quarterly and to report annually entity-wide disclosures about products, major customers and the geographies in which the entity holds material assets and reports revenue. An operating segment is defined as a component that engages in business activities whose operating results are reviewed by the chief operating decision maker ("CODM") and for which discrete financial information is available. For purposes of evaluation under these segment reporting principles, the CODM assesses the Company's ongoing performance based on the periodic review of net sales, Adjusted EBITDA and certain other measures for each of the operating segments. Based on the provisions of ASC 280, the Company has determined that it has seven operating segments. These operating segments are based on the six geographic divisions, which are Central, Northeast, Southern, Southeast, Southwest and Western. Due to similarities between the geographic operating segments, we have aggregated them into one reportable segment in accordance with ASC 280. The accounting policies of the operating segments are the same as those described in the summary of significant policies. In addition to our reportable segment, the Company's consolidated results include corporate activities, which includes our corporate office building and related yard support activities and Tool Source Warehouse, Inc., which functions primarily as an internal distributor of tools. The Company has revised its prior year presentation of segment Total Assets and Depreciation and Amortization to record $6,918 of corporate assets as of April 30, 2015 and corporate Depreciation and Amortization of $741, $42 and $397 for the Successor 2015, Successor 2014 and Predecessor 2014 periods, respectively, originally disclosed as part of "Geographic divisions". In addition, in its "Geographic divisions" segment the Company has increased accounts receivable by $1,051 as of April 30, 2015 and increased net sales by $12,523, $858 and $9,421 for Successor 2015, Successor 2014 and Predecessor 2014 periods, respectively, to correct amounts which were previously reflected in "Other." The prior year misclassification was not material to the previously issued financial statements. In connection with the current year presentation, the Company has also reclassified its "Corporate" related balances out of "Other". Net sales, Adjusted EBITDA and certain other measures for the reportable segment and total continuing operations for the periods indicated are as follows:
