COMPANY OVERVIEW

Unless the context otherwise indicates or requires, as used in this Annual Report on Form 10-K, the terms "we," "our," "us," "ADS" and the "Company" refer to Advanced Drainage Systems, Inc. and its directly- and indirectly-owned subsidiaries as a combined entity, except where it is clear that the terms mean only Advanced Drainage Systems, Inc. exclusive of its subsidiaries. The term "Infiltrator" refers to Infiltrator Water Technologies Ultimate Holdings, Inc., our wholly owned subsidiary.

ADS is the leading manufacturer of innovative water management solutions in the stormwater and onsite septic wastewater industries, providing superior drainage solutions for use in the construction and agriculture marketplaces. Our innovative products are used across a broad range of end markets and applications, including non-residential, infrastructure and agriculture applications. We have established a leading position in many of these end markets by leveraging our national sales and distribution platform, industry-acclaimed engineering support, overall product breadth and scale plus manufacturing excellence.

We believe the ADS brand has long been associated with quality products and market-leading performance. Our trademarked green stripe, which is prominently displayed on many of our products, serves as clear identification of our commitment to the customers and markets we serve, and fortifies our brand recognition and presence.

Our approach to water management is based on four basic areas - Capture, Conveyance, Storage, and Treatment - to manage the lifecycle of a raindrop from the moment water hits the ground until it is released back into the ecosystem. Our product portfolio is built around each step of this lifecycle. Our solutions safely and efficiently manage stormwater with environmentally friendly products. We believe we are the only water management solutions company that manages stormwater from when the rain first hits the ground until the moment it is returned to lakes and streams.

•Capture: As the first step in preserving the planet's most precious resource, water, our products collect and direct stormwater runoff on project sites and roads to an underground conveyance system.

•Conveyance: To prevent flooding at job sites, which could lead to significant structural and environmental problems, our pipe, fittings and other products safely move stormwater away from developed sites to be reintroduced back into the water cycle.

•Storage: To mitigate erosion and flooding, our retention and detention systems manage infiltration and recharge stormwater prior to the treatment process.

•Treatment: Our water quality products remove trash, debris and pollutants from the stormwater runoff and septic systems, ensuring only clean water is discharged back into our communities.

We estimate that the storm water industry, annually, is an approximately $6 billion industry. We estimate that the onsite septic market is a roughly $1 billion industry and that approximately 30% of new North American single-family homes utilize septic systems. On a combined basis, we estimate that we had an addressable market opportunity of approximately $7 billion.

Pipe

Dual Wall Corrugated Pipe - Our N-12 pipe is a dual wall high-density polyethylene ("HDPE") pipe with a corrugated exterior for strength and a smooth interior wall for hydraulics and flow capacity. Our N-12 pipe competes in the storm sewer and drainage markets that are also served by concrete pipe. Our N-12 pipe is available in a wide range of diameters and sections of length. N-12 provides joint integrity, with integral bell and spigot joints for fast push-together installations and is sold either with watertight or soil-tight coupling and fitting systems.

Our corrugated polyethylene pipe offers many benefits including ease of installation, job-site handling and resistance to corrosion and abrasion. Corrugated pipe can easily be cut or coupled together, providing precise laying lengths while minimizing installation waste and difficulty.

HP Storm Pipe and SaniTite HP Pipe - Our HP Storm pipe utilizes polypropylene ("PP") resin, which provides (i) increased pipe stiffness relative to HDPE; (ii) higher Environmental Stress Crack Resistance ("ESCR"); and (iii) improved thermal properties, which improves joint performance. These improved physical characteristics result in a reduced need for select backfill, which creates installation savings for customers and expands the range of possible product applications.

Our SaniTite HP pipe utilizes the same polypropylene resins as our HP Storm pipe but includes a smooth third exterior wall in 30" to 60" pipe. The highly engineered polypropylene resin along with the triple wall design enables SaniTite HP to surpass the stiffness requirement for sanitary sewer applications. SaniTite HP offers cost and performance advantages relative to reinforced concrete pipe (such as improved hydraulics and better joint integrity) and polyvinyl chloride ("PVC") pipe (such as impact resistance).

Single Wall Corrugated Pipe - Our single wall corrugated HDPE pipe is ideal for drainage projects where flexibility, light weight and low cost are important. Single wall HDPE pipe products have been used for decades in agricultural drainage, highway edge drains, septic systems and other construction applications. In the agricultural market, improved technology has highlighted the favorable impact of drainage on crop yields. For homeowners, it is an economical and easily installed solution for downspout run-off, foundation drains, driveway culverts and general lawn drainage. Single wall pipe is also used for golf courses, parks and athletic fields to keep surfaces dry by channeling away excess underground moisture.

Standard single wall products are available in a wide range of diameters and sold in varying lengths. Pipe can be either perforated or non-perforated depending on the particular drainage application.

Triple Wall Corrugated Pipe and Smoothwall HDPE Pipe - Our ADS-3000 Triple Wall pipe, small diameter triple wall corrugated pipe, consists of a corrugated polyethylene core molded between a smooth white outer wall and a smooth black inner wall. This combination of the three wall design adds strength and stiffness, while reducing weight as compared to PVC 2729. Triple Wall is produced and sold through our distribution network. We also manufacture smoothwall HDPE pipe that are sold into the residential drainage and onsite septic systems markets.

Infiltrator

Infiltrator is the leading designer and manufacturer of highly engineered plastic chambers, synthetic aggregate leachfields, combined treatment and dispersal systems, plastic tanks, active treatment systems, and related accessories that are used in septic systems and decentralized commercial wastewater treatment systems. The onsite wastewater (septic) market is heavily reliant on rural homes and communities that do not have access to centralized sewer and will require an onsite wastewater or septic solution. Onsite wastewater technologies are scalable and can easily meet the needs of churches, schools, light commercial and small community construction projects.

Leachfield Products- Our Quick4 and Arc line of septic leachfield chambers are injection molded using recycled polyolefin materials. There are Quick4 chamber models available to meet a wide variety of regulatory and market needs. There are Arc chamber models available to meet a majority of regulatory and market needs. The Quick4 and Arc chambers are engineered for strength and performance, easy to install, and offer the user greater design flexibility, including a smaller footprint, as compared with traditional stone and pipe products. The product advantages are cost savings on labor, materials and time savings on the job.

EZflow - EZflow synthetic aggregate bundles replace stone and pipe leachfields for effluent and drainage applications. The EZflow proprietary products are a modular design that incorporates recycled polystyrene aggregate bundles and corrugated polyethylene pipe that act as a replacement to the traditional materials stone and pipe.

Tank Products - Our IM-Series line of septic tanks are injection-molded polypropylene plastic tanks manufactured from recycled materials. IM-Series septic tanks are available in various capacities for wastewater storage. Our IM-Tank is the only two-piece construction, injection molded tank design in North America. In comparison to traditional concrete tanks, our IM-Series septic tanks are easier to transport to the jobsite and require less time and energy to install.

Our IM-Series line of potable tanks are injection-molded polypropylene plastic tanks manufactured from virgin materials suitable for water reuse and drinking water storage. IM-Series potable tanks are available in various capacities for water storage. IM-Series potable tanks are commonly used in water cistern applications, such as rainwater harvesting systems.

Delta Treatment Systems - Our Delta Treatment Systems' ("Delta") wastewater treatment systems provide a higher level of wastewater purification through mechanical aeration wastewater for residential and commercial systems with daily flows up to 100,000 gallons per day.

Presby Treatment Dispersal Systems - Our Presby Environmental Enviro-Septic and Advanced Enviro-Septic systems are proprietary combined treatment and dispersal systems made with a twelve-inch diameter corrugated extrusion product that is encapsulated in fibrous materials and geotextiles. These systems when installed in a bed of sand provide combined treatment and dispersal in the same small footprint and at a reduced cost with minimal long-term maintenance. .

Advanced Treatment Leachfield - Our Advanced Treatment Leachfield ("ATL") product is an alternative combined treatment and dispersal system that provides advanced wastewater treatment. The ATL is a profile of polystyrene aggregates and geotextiles installed in a bed of sand.

Allied Products & Other

We produce a range of Allied Products that are complementary to our Pipe products. Our Allied Products offer adjacent technologies to our core Pipe offering, presenting a complete drainage solution for our clients and customers. This combination of Pipe and Allied Products is a key strategy in our sales growth, profitability and market share penetration. The practice of selling a drainage system is attractive to both distributors and end users, by providing a broad package of products that can be sold on individual projects and strengthens our competitive advantage in the marketplace. We aggressively seek and evaluate new products, technologies and regulatory changes that impact our customers' needs for Allied Products.

The underground construction industry has historically been project (not product) driven, creating the impetus for owners, engineers and contractors to seek manufacturers that deliver solution-based product portfolios. Many of the components of underground construction are related and require linear compatibility of function, regulatory approval and technology.

Storm Chambers - Our StormTech chambers are used for stormwater retention, detention and "first flush" underground water storage on non-residential site development and public projects. These highly engineered chambers are injection molded from HDPE and PP resins into a proprietary design which provides strength, durability, and resistance to corrosion. The chambers allow for the efficient storage of stormwater volume, reducing the underground construction footprint and costs to the contractors, developers, and property owners. The chambers are open bottom, which allows for high density stacking in both storage and shipment. This freight-efficient feature drives favorable cost-competitiveness in serving long-distance export markets. These chamber systems typically incorporate our other product lines such as corrugated pipe, fabricated fittings, water quality units and geotextiles.

Structures - Our Nyloplast PVC drainage structures are used in non-residential, residential and municipal site development, road and highway construction, as well as landscaping, recreational, industrial and mechanical applications. The product family includes inline drains, drain basins, curb inlets and water control structures which move surface-collected stormwater vertically down to pipe conveyance systems. These custom structures are fabricated from sections of PVC pipe using a thermo-forming process to achieve exact site-specific hydraulic design requirements. Our Nyloplast products are a preferred alternative to heavier and larger concrete structures, by offering greater design flexibility and improved ease of installation which reduces overall project costs and timelines. The structures incorporate rubber gaskets to ensure watertight connections, preventing soil infiltration which plagues competitive products.

Fittings - We produce fittings and couplings utilizing blow molding, injection molding and custom fabrication on our pipe products. Our innovative coupling and fitting products are highly complementary to our broader product suite, and include both soil-tight and water-tight capabilities across the full pipe diameter spectrum. Our fittings are sold in all end markets where we sell our current pipe products.

Other Products - Our ARC and BioDiffuser products are chambers that are used in septic systems for residential and small volume non-residential wastewater treatment and disposal. The innovative design of our ARC chamber is generally approved for a footprint reduction, further reducing the cost of the septic system. Injection-molded from HDPE, these products are strong, durable, and chemical-resistant. These interconnecting chambers are favored by septic contractors because they are lightweight, easy to install and offer articulating features which increase site-specific design flexibility. The ARC chamber products are manufactured by Infiltrator.

Our Water Quality (formerly BaySaver) product line targets the removal of sediment, debris, oils and suspended solids throughout a stormwater rain event by separating and/or filtering unwanted pollutants.

We purchase and distribute construction fabrics and other geosynthetic products for soil stabilization, reinforcement, filtration, separation, erosion control, and sub-surface drainage. Constructed of woven and non-woven PP, geotextile products provide permanent, cost-efficient site-development solutions. Construction fabrics and geotextiles have applications in all of our end markets.

Our Inserta Tee product line consists of a PVC hub, rubber sleeve and stainless steel band. Inserta Tee is compression fit into the cored wall of a mainline pipe and can be used with all pipe material types and profiles. This product offers an easy tap-in to existing sanitary and storm sewers by limiting the excavation needed for installation compared to competitive products.

RAW MATERIALS AND SUPPLIERS

Virgin HDPE and PP resins are derivatives of ethylene and propylene, respectively. Ethylene and propylene are derived from natural gas liquids or crude oil derivatives primarily in the U.S. We currently purchase in excess of 1.3 billion pounds of virgin and recycled resin annually from approximately 500 suppliers. As a high-volume buyer of resin, we achieve economies of scale to negotiate favorable terms and pricing. Our purchasing strategies differ based on the material (virgin resin versus recycled material) ordered for delivery to our production locations.

The price movements of the different materials also vary, resulting in the need to use strategies to reduce volatility and successfully pass on cost increases to our customer through timely selling price increases when needed.

We have relationships with most of the North American producers of virgin high-density polyethylene and impact copolymer polypropylene producers that manufacture the grades we need to produce our products. The North American capacity for ethylene derivatives has been expanded primarily as a result of supplies of natural gas liquids being produced through sustained oil and gas exploration and production.

We are focused on a program of continuous sustainability improvement, with approximately 600 million pounds of post-consumer recycled high-density polyethylene ("HDPE") currently used to make our products. This industry-leading program keeps millions of used bottles out of the landfill and puts them to work again for more than a hundred years as part of our infrastructure.

We leverage our raw material blending and processing technologies to produce an HDPE pipe that incorporates recycled resin. These products, which meet an ASTM International standard and an American Association of State Highway and Transportation Officials standard, replaces a majority of the virgin resin that is used with optimized recycled materials. ADS Recycling procures and processes recycled raw materials that can be used in products we produce and sell. On December 3, 2021, we completed the acquisition of Jet Polymer Recycling, Inc. ("Jet"). The acquisition of Jet expands the Company's plastic recycling capabilities to support future growth. Jet is the largest supplier of recycled polypropylene plastic for Infiltrator.

We maintain relationships with several of the largest environmental companies which provide us with post-consumer HDPE recycled materials. We also maintain relationships with several key post-industrial HDPE suppliers which provide us with materials that cannot otherwise be utilized in their respective production processes.

We are one of the largest domestic recyclers of HDPE. We believe that we are well positioned for future growth as we add additional recycled material processing facilities, add capacity to existing facilities, and expand our supplier base for virgin resin. We anticipate continued growth in the availability of ethylene and propylene which are used to manufacture HDPE and PP, respectively.

OUR MANUFACTURING AND DISTRIBUTION PLATFORM

We have a leading domestic and international manufacturing and distribution infrastructure, serving customers throughout the United States, Canada, Mexico and other countries worldwide through 70 manufacturing plants and 38 distribution centers, including eight manufacturing plants and nine distribution centers owned or leased by our joint ventures. We manufacture our corrugated pipe products using a continuous extrusion process, where molten polyethylene or polypropylene is pushed through a die into a moving series of corrugated U-shaped molds. We utilize customized and proprietary production equipment, which we believe is faster and more cost efficient than other pipe making equipment generally available in the market.

Domestically, we can produce more than one billion pounds of pipe annually. Additional capacity is in place to support seasonal production needs and expected growth. Our production equipment is built to accept transportable molds and die tooling over a certain range of sizes so each plant is not required to house the full range of tooling at any given time. This transportability provides us with the flexibility to optimize our capacity through centrally coordinated production planning, which helps to adapt to shifting sales demand patterns while reducing the capital needed for tooling. With our large manufacturing footprint in place, we can support rapid seasonal growth in demand, focusing on customer service while minimizing transportation costs.

Our manufacturing plants have no material process-related by-products released into the atmosphere, waterways, or solid waste discharge. During pipe production start-ups and size changeovers, non-compliant scrap and any damaged finished goods pipe are recycled through a grinder for internal re-use.

The standard fittings products (tees, wyes, elbows, etc.) that we produce and sell to connect our pipe on jobsites are blow molded or injection molded at three domestic plants. In addition, customized fabricated fittings (e.g., more complex dual wall pipe reducers, bends or structures) are produced in 20 of our North American plants. A wide variety of production processes and expertise allow us to provide cost-effective finished goods at competitive prices delivered in a timely fashion to our customers.

We produce storm and septic chambers, tanks and accessories using injection molding machines ranging in size. Our molds and machines have been designed to maximize interchangeability to optimize flexibility, maximize efficiency and minimize downtime.

International Presence - We own manufacturing facilities in Canada to produce our products for sale in the Canadian markets. We serve international markets primarily in Mexico, Central America and South America through joint venture operations with local partners. Our joint venture strategy has provided us with local and regional access to key markets such as Mexico, Brazil, Chile, Argentina, and Peru. Our international joint ventures produce pipe and related products to be sold in their respective regional markets. We also have wholly-owned subsidiaries that distribute our pipe and related products in Europe and the Middle East. Combining local partners' customer relationships, brand recognition and local management talent, with our world-class manufacturing and process expertise, broad product portfolio and innovation creates a powerful solution driven platform and opportunities for continued profitable international expansion.

Quality Assurance Control - We have two internal quality assurance control laboratory facilities equipped and staffed to evaluate and confirm incoming raw material and finished goods quality in addition to the quality testing that is done at our manufacturing facilities. We conduct annual safety, product and process quality audits at each of our facilities, using centralized internal resources in combination with external third-party services. In the quality area, various national and international agencies such as National Transportation Product Evaluation Program ("NTPEP"), International Association of Plumbing and Mechanical Officials ("IAPMO"), Bureau de normalisation du Québec ("BNQ"), Intertek for Canadian Standards Association ("CSA"), Entidad Mexicana de Acreditacion A.C. ("EMA") and NSF International and several state Departments of Transportation ("DOT") and municipal agencies conduct both scheduled and unscheduled audits/inspections of our plants to verify product quality and compliance to applicable standards.

Fleet - We also operate an in-house fleet of approximately 700 tractors. Our effective shipping radius is approximately 300 miles from one of our manufacturing plants or distribution centers. The combination of a dedicated fleet and team of company drivers allows greater flexibility and responsiveness in meeting dynamic customer jobsite delivery expectations. We strive to achieve less than three-day lead-time on deliveries and have the added benefit of redeploying fleet and driver assets to respond to short-term regional spikes in sales activity. For deliveries that are outside an economic delivery radius of our truck fleet, common carrier deliveries are tendered to a third-party control tower to ensure that lowest delivered freight costs are achieved while maintaining high levels of customer service. In addition, we are committed to continuously upgrading our tractors with state-of-the-art safety features, fuel economy, and digital technology to attract the driver of the future, reduce our total emissions and keep our drivers safe on and off the road.

Our North American truck fleet incorporates approximately 1,300 trailers that are specially designed to haul our lightweight pipe and Allied products. These designs maximize payload versus conventional over the road trailers and facilitate the loading and unloading of our products at the various customer delivery locations. The new trailer design assists in managing the fuel efficiency of our fleet by decreasing total trailer weight and aerodynamic design. The scope of fleet operations also includes backhaul throughout our network to lower our total delivered cost and increase our asset utilization.

Facility Network - Our scale and extensive network of Pipe and Allied Products facilities provide a critical cost advantage versus our competitors, as we are able to more efficiently transport products to our customers and end users and to promote faster product shipments due to our proximity to the delivery location. The optimized design of our Infiltrator chambers and tanks provide the ability to nest products, enabling us to manufacture products from one location and efficiently ship throughout North America.

Selling to buying groups and co-ops provides us a further presence on a national, regional and local basis for the distribution of our products. Our preferred vendor status with these groups allows us to reach thousands of locations in an effective manner. Members of these groups and co-ops generally are independent businesses with strong relationships and brand recognition with smaller contractors and homeowners in their local markets. The combination of our large sales force, long-standing retail and contractor customer relationships and extensive network of manufacturing and distribution facilities complements and strengthens our broad customer and market coverage.

Our customer service organization is supplemented by the employees of our manufacturing plants, distribution centers and drivers of our tractor-trailers. In conjunction with our field sales and engineering team, this highly trained and competent staff allows us to maintain more customer touch points and interaction than any of our competitors.

SEASONALITY

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

In the non-residential, residential and infrastructure markets in the northern United States and Canada, construction activity typically begins to increase in late March and is slower in December, January and February. In the southern and western United States, Mexico, Central America and South America, the construction markets are less seasonal.

The agricultural drainage market is concentrated in the early spring just prior to planting and in the fall just after crops are harvested prior to freezing of the ground in winter.

PRACTICES RELATED TO WORKING CAPITAL ITEMS

Information about the Company's working capital practices is incorporated herein by reference to "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations - Results of Operations - Working Capital and Cash Flows" of this Form 10-K.

COMPETITION

We operate in a highly fragmented industry and hold leading positions in multiple market sectors. Competition, including our competitors and specific competitive factors, varies for each market sector.

Our products are generally lighter, more durable, more cost effective and easier to install than comparable alternatives made with traditional materials.

In the United States, our nationwide footprint combined with our strong local presence and broad product offering make us the leader in an otherwise highly fragmented sector comprised of many smaller competitors.

We believe the principal competitive factors for our market sectors include local selling coverage, product availability, breadth and cost of products, technical knowledge and expertise, customer and supplier relationships, reliability and accuracy of service, effective use of technology, delivery capabilities and timeliness, pricing of products, and the provision of credit. We believe that our competitive strengths and strategy allow us to compete effectively in our market sectors.

The stormwater drainage industry, in particular, is highly fragmented with many smaller specialty and regional competitors providing a variety of product technologies and solutions. We compete against concrete pipe, corrugated steel pipe and PVC pipe producers on a national, regional and local basis. In addition, there are many HDPE pipe producers in the United States. We believe we are the only corrugated HDPE pipe producer with a national footprint, and our competitors operate primarily on a regional and local level.

INTELLECTUAL PROPERTY

We rely upon a combination of patents, trademarks, trade names, licensing arrangements, trade secrets, know-how and proprietary technology in order to secure and protect our intellectual property rights, both in the United States and in foreign countries.

We seek to protect our new technologies with patents and trademarks and defend against patent infringement allegations. We hold a significant amount of intellectual property rights pertaining to product patents, process patents and trademarks. We continually seek to expand and improve our existing product offerings through product development and acquisitions. Although our intellectual property is important to our business operations and in the aggregate constitutes a valuable asset, we do not believe that any single patent, trademark or trade secret is critical to the success of our business as a whole. We cannot be certain that our patent applications will be issued or that any issued patents will provide us with any competitive advantages or will not be challenged by third parties.

In addition to the foregoing protections, we generally control access to and use of our proprietary and other confidential information through the use of internal and external controls, including contractual protections with employees, distributors and others. See "Item 1A. Risk Factors - Risks Relating to Our Business - If we are unable to protect our intellectual property rights, or we infringe on the intellectual property rights of others, our ability to compete could be negatively impacted."

Health and Safety- Employee safety is our highest priority and a key component of our company culture. Our operations follow a comprehensive, proactive safety and health management system that includes a collaborative process to find and fix workplace hazards prior to injury occurrence. Our U.S. facilities follow all Occupational Safety and Health Act ("OSHA") safety and health standards, as required by law; and our Canadian facilities follow the Canadian Federation of Construction Safety Association ("CFCSA") Certificate of Recognition ("COR") program, as required by law.

Our priority in response to the COVID-19 pandemic continues to be the health and safety of our employees. Deemed an essential business, we maintain appropriate health protocols across all our facilities so we could remain open to deliver critical water management solutions to our customers and the communities they serve. To further minimize risk, we used a thorough case management process to work through and mitigate any potential cases.

Values- Our success as a company is built on the Honesty, Professionalism, and Core Values of our employees, directors, and agents. These three tenets serve as the guiding principles of our Code of Business Conduct and Ethics (the "Ethics Code").

•Honesty: We believe in always being honest in dealing with our customers, suppliers, and others and complying with all laws and regulations applicable to our business at all levels.

•Professionalism: We believe in providing our products and services in a prompt and professional manner, gaining the loyalty and trust of our customers and suppliers.

•Core Values: We believe in certain "core values" centered upon ensuring quality throughout our product and organization for long-term growth and profitability.

The Ethics Code provides a framework by which we maintain the highest ethical standards in the conduct of our business and is an integral part of implementing our vision of ethically and sustainably maximizing value. All members of our organization are expected to adhere to each of the policies of the Ethics Code, while also employing good ethical judgment. The Ethics Code provides guidelines in relation to conflicts of interest, fair dealing, confidential information and intellectual property, fair employment practices, environmental health and safety, and improper payments to third parties, among many other areas of ethical business conduct.

Diversity, Equity and Inclusion- As a global company, we are dedicated to fostering an inclusive culture, empowering employees and communities by embracing the dynamics of different backgrounds, experiences and perspectives. We are committed to creating an environment where employees feel valued, respected, and fully engaged to contribute to our future success.

We base hiring and promotional decisions on job qualifications, such as work records, performance history and length of service, to ensure equal opportunity to all. We also ensure equal opportunity across all relevant aspects of employment such as recruiting, job assignment, compensation, benefits, transfers, promotional opportunities, Company sponsored training, and recreation programs, among others.

Training- Our operational and management training programs are core to our commitment and enablement of a safe and productive manufacturing environment. Through our ADS Academy, we deliver targeted role-specific training to our operations team members through a blended curriculum of online and hands-on training experiences covering safety, quality, product knowledge and manufacturing process. Our learning management system, which hosts approximately 450 custom modules, serves as the foundation of our operational training programs and provides us with appropriate scale,

efficiency, and governance to support our growth. We have a strong commitment to the training of our manufacturing supervisors and managers in technical, management, and leadership subjects through intense role-based assimilation plans, e-learning and classroom-based development experiences.

REGULATION

Our operations are affected by various statutes, regulations and laws in the markets in which we operate, which historically have not had a material effect on our business. We are subject to various laws applicable to businesses generally, including laws affecting land usage, zoning, the environment, health and safety, transportation, labor and employment practices, competition, immigration and other matters. Additionally, building codes may affect the products our customers are allowed to use, and, consequently, changes in building codes may affect the salability of our products. The transportation and disposal of many of our products are also subject to federal regulations. We are subject to safety requirements governing interstate operations prescribed by the U.S. Department of Transportation ("U.S. DOT"). Vehicle dimensions and driver hours of service also remain subject to both federal and state regulation.

We have been able to consistently capitalize on changes in both local and federal regulatory statutes relating to storm and sanitary sewer construction, repair and replacement. Most noteworthy is the Federal Clean Water Act of 1972 and the subsequent EPA Phase I, II and sustainable infrastructure regulations relating to storm sewer construction, storm water quantity, storm water quality, and combined sewer separation. Our diversity of products offering a solution-based selling approach coupled with detailed market knowledge makes us an integral industry resource in both regulatory changes and compliance.

An important element of our growth strategy has been our focus on industry education efforts to drive regulatory approvals for our core HDPE products at national, state and local levels. We employ field-based engineers who work closely with government agencies to obtain regulatory approvals for our products, and also with civil engineering firms to specify our products on non-residential construction and road-building projects. Additional state and local regulatory approvals will continue to present new growth opportunities in new and existing geographic markets for us. The trend of substituting traditional materials for HDPE and PP is expected to continue as more states and municipalities recognize the benefits of our HDPE N-12 pipe and our polypropylene HP pipe by approving it for use in a broader range of applications.

Our Infiltrator products are used primarily in onsite septic and decentralized wastewater treatment systems. The products used in these systems cannot be sold without a regulatory approval. We have a dedicated regulatory team with a track record of gaining favorable regulatory approvals and advancing policy and legislation. Over the past 10 years the team has successfully embarked in over 100 regulatory initiatives increasing the addressability and size of markets across the U.S. and Canada.

ENVIRONMENTAL, HEALTH AND SAFETY MATTERS

We are subject to a broad range of foreign, federal, state and local environmental, health and safety laws and regulations, including those pertaining to air emissions, water discharges, the handling, disposal and transport of solid and hazardous materials and wastes, the investigation and remediation of contamination and otherwise relating to health and safety and the protection of the environment and natural resources. To a limited extent, our current and past operations, and those of many of the companies we have acquired, involve materials that are, or could be classified as, toxic or hazardous. There is inherent risk of contamination and environmental damage in our operations and the products we handle, transport and distribute. See "Item 1A. Risk Factors - Risks Relating to Our Business - We could incur significant costs in complying with environmental, health and safety laws or permits or as a result of satisfying any liability or obligation imposed under such laws or permits."

Item 1A. Risk Factors

Please carefully consider the risks described below, together with all other information included or incorporated by reference in this Annual Report on Form 10-K. If any of the following risks actually occur, our business, financial condition, results of operations and cash flows could be materially adversely affected. In these circumstances, the market price of our common stock could decline significantly.

Risks Relating to Our Business

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

The principal raw materials that we use in our products are virgin and recycled resins. Our ability to operate profitably depends, to a large extent, on the markets for these resins. In particular, as resins are derived either directly or indirectly from crude oil derivatives and natural gas liquids, resin prices fluctuate substantially as a result of changes in crude oil and natural gas prices, changes in existing processing capabilities and the capacity of resin suppliers. Polypropylene resin suppliers are limited, high-density polyethylene suppliers are geographically concentrated and supply of recycled resin is also limited. Supply interruptions could arise from disruptions to existing petrochemical capacity and recycled resin sources caused by labor disputes and shortages, weather conditions or natural disasters affecting supplies or shipments, transportation disruptions or other factors beyond our control. An extended disruption in the timely availability of raw materials from our key suppliers would result in a decrease in our revenues and profitability. Additionally, our customers' production schedules could be impacted by these shortages, which could result in reduced sales of our products.

Inflation in these raw material costs could also result in significant cost increases, further affecting our business. Our ability to maintain profitability heavily depends on our ability to pass through to our customers any increase in raw material costs, which are a large portion of our overall product costs. If increases in the cost of raw materials, including resins, cannot be passed on to our customers, or the duration of time associated with a pass through becomes extended, our business, financial condition, results of operations and cash flows will be adversely affected. Conversely, in the event that there is deflation, we may experience pressure from our customers to reduce prices. There can be no assurance that we would be able to reduce our cost base to offset any such price concessions which could adversely impact our results of operations and cash flows.

The COVID-19 pandemic or other pandemics in the future, could have a significant negative impact on our operations, liquidity, financial condition and financial results.

The ongoing COVID-19 pandemic has negatively impacted the global economy, in addition to disrupting global supply chains and workforce participation. Quarantines and "stay in place" orders, the timing and length of containment and eradication solutions, travel restrictions, absenteeism by infected workers, labor shortages or other disruptions to our supply chain or our customers could adversely impact our sales and operating results. While manufacturing and manufacturing-related industries are considered an "essential service" in most jurisdictions in which we operate, site closures or project delays have occurred and increased social distancing and health-related precautions are required on many work sites, which may cause additional project delays and additional costs to be incurred.

To the extent that our customers and suppliers are adversely impacted by the COVID-19 pandemic, this could reduce the availability, or result in delays, of materials or supplies, or delays in customer payments, which in turn could materially interrupt our business operations and/or impact our liquidity.

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

The markets in which we operate are sensitive to general business and economic conditions in the U.S. and worldwide, including availability of credit, interest rates, fluctuation in capital and business and consumer confidence. Furthermore, the U.S. and global economy as well as the markets in which we operate face the adverse impact of the COVID-19 global

14

Advanced Drainage Systems, Inc.

pandemic, as referenced above. The difficult conditions in these markets and the overall economy affect our business in a number of ways. For example:

•The volatility of the U.S. economy can have an adverse effect on our sales that are dependent on the non-residential construction market if participants in this industry may postpone spending.

•Our business depends upon general activity levels in the agriculture market. The nature of the agriculture market is such that a downturn in demand can occur suddenly, resulting in excess inventories, un-utilized production capacity and reduced prices for pipe products. These downturns may be prolonged, and our revenue and profitability would be harmed.

•Our business depends on the residential construction market. While new housing starts demonstrated a compounded annual growth rate of 6.4% from 2016 to 2021, current levels remain below the long-term average of 1.4 million starts since the U.S. Census Bureau began reporting the data demand for our products and services in this market, which in turn would result in a significant adverse effect on our financial condition and results of operations.

•Demand for our products and services depend to a significant degree on spending on infrastructure. Infrastructure spending is affected by a variety of factors beyond our control, including interest rates, availability and commitment of public funds for municipal spending and highway spending and general economic conditions.

Weakness in the markets in which we operate could have a material adverse effect on our business, financial condition, results of operations and cash flows. We may have to close under-performing facilities as warranted by general economic conditions and/or weakness in the markets in which we operate. In addition to a reduction in demand for our products, these factors may also reduce the price we are able to charge for our products and restrict our ability to pass raw material cost increases to our customers. This, combined with an increase in excess capacity, will negatively impact our profitability, cash flows and our financial condition, generally.

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

We compete with both manufacturers of high performance thermoplastic corrugated pipe and manufacturers of alternative products, such as concrete, steel and PVC pipe products, on the basis of a number of considerations, including product characteristics such as durability, design, ease of installation, price on a price-to-value basis and service.

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

Certain of our competitors have financial and other resources that are greater than ours and may be better able to withstand price competition, especially with respect to traditional products. In addition, consolidation by industry participants could result in competitors with increased market share, larger customer bases, greater diversified product offerings and greater technological and marketing expertise, which would allow them to compete more effectively against us. Moreover, our competitors may develop products that are superior to our products or may adapt more quickly to new technologies or evolving customer requirements. In many markets in which we operate there are no significant entry barriers that would prevent new competitors from entering the market, especially on the local level, or existing competitors from expanding in the market.

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

Many of our products are made from a material whose manufacturing process involves the emission of carbon dioxide, a greenhouse gas ("GHG") that scientists have attributed as a cause of climate change. Our products require transportation from our facilities to the site where they are used, which consumes energy. Concern over climate change, including the impact of global warming, has led to federal, state, and international efforts to limit GHG emissions. Although it is uncertain at this time precisely what actions various governmental bodies will take early to address the effects of climate change and to achieve goals in response to the potential effects of climate change, including in what timeframe those actions would be implemented, new laws or future regulations could directly and indirectly affect our customers and suppliers (through an increase in the cost of production or their ability to produce satisfactory products) and our business (through the impact on our inventory availability, cost of sales, operations or demands for the products we sell). Until the timing, scope and extent of any future regulation becomes known, we cannot predict its effect on our cost structure or our

15

Advanced Drainage Systems, Inc.

operating results, but it is likely our costs will increase in relation to any climate change legislation and regulations concerning GHG, which could have an adverse effect on our future financial position, results of operations or cash flows.

In January 2022, we communicated our initial 10-year goals regarding sustainability. To reduce our Environmental Impact, we have committed to pursuing science-based targets consistent with limiting global temperature increase to 1.5°C above pre-industrial levels. We are working to define absolute targets for reduction of scope 1 (direct) & 2 (indirect) greenhouse gas emissions ("GHG") that align with limiting future temperature rise to 1.5°C above baseline. These goals reflect our current plans and there is no guarantee that they will be achieved. Our ability to achieve any goal is subject to factors and conditions, many of which are outside of our control, including technology,or the availability of recycled resin.

Notwithstanding our commitment to advancing sustainable business practices, climate change may also have adverse physical or financial impacts on our business to the extent that it causes more severe or more frequent major storm events, flooding, drought-induced wildfires, or other shifts in weather patterns. Increases in the intensity and frequency of acute weather events have been linked to climate change, and this risk may increase to the extent global warming continues or is unabated. These types of extreme weather events may include disruptions to operations or production, disruptions to supply chains or damage to our physical plants, which could lead to reduced financial performance of our business.

In addition, regardless of whether governmental bodies enact legislation to address climate change and reduce GHG emissions or we achieve our 10-year goals, the public perception of carbon-intensive industries may change adversely over time and additional focus on environmental, social and governance issues by the public and/or investors may harm our business as it could damage our reputation, require us to expend resources in reducing our net carbon emissions, or reduce demand for our products, which could adversely impact our results of operations and cash flows.

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

Most of our business units experience seasonal variation as a result of the dependence of our customers on suitable weather to engage in construction projects. Generally, during the winter months, construction activity declines due to inclement weather, frozen ground and shorter daylight hours. In addition, to the extent that hurricanes, severe storms, floods, other natural disasters or similar events occur in the geographic regions in which we operate, our results of operations may be adversely affected. We anticipate that fluctuations of our operations results from period to period due to seasonality will continue in the future

The loss of any of our significant customers could adversely affect our business.

Our ten largest customers generated approximately 40% of our net sales in fiscal 2022. Because we do not have long-term arrangements with many of our customers, such customers may cease purchasing our products without notice or upon short notice to us. In addition, consolidation among customers could also result in a loss of some of our present customers to our competitors. The loss of one or more of our significant customers, a significant customer's decision to purchase our products in significantly lower quantities than they have in the past, or deterioration in our relationship with any of them could have a material adverse effect on our business, financial condition, results of operations and cash flows.

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

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

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

We may be unable to successfully integrate businesses to realize the anticipated benefits of acquisitions or do so within the intended timeframe.

The success of any acquisition, including anticipated synergies, benefits and cost savings, will depend, in part, on our ability to successfully combine and integrate our current operations with the acquisition. If we experience difficulties with the integration process or other unforeseen costs, the anticipated benefits and cost savings of the acquisition may not be realized fully or may take longer to realize than expected. The integration planning and implementation process will result in significant costs and divert management attention and resources. These integration matters could have an adverse effect on our combined company for an undetermined period after completion of the acquisition. In addition, the actual cost savings of the acquisition could be less than anticipated, or otherwise offset by other factors.

Our international operations expose us to political, economic and regulatory risks not normally faced by businesses that operate only in the U.S. As a result of our international operations, we could be adversely affected by violations of the U.S. Foreign Corrupt Practices Act and similar foreign anti-corruption laws.

Some of our operations are outside the U.S., with manufacturing and distribution facilities in Canada and several Latin American countries. Our international operations are subject to risks similar to those affecting our operations in the U.S. in addition to a number of other risks, including: difficulties in enforcing contractual and intellectual property rights; impositions or increases of withholding and other taxes on remittances and other payments by subsidiaries and affiliates; exposure to different or changing legal standards, including potential changes in government mandated regulatory product standards in those countries in which we or our joint ventures operate; fluctuations in currency exchange rates; impositions or increases of investment and other restrictions by foreign governments; the requirements of a wide variety of foreign laws; political and economic instability; war; and difficulties in staffing and managing operations, particularly in remote locations.

The U.S. Foreign Corrupt Practices Act ("FCPA") and similar foreign anti-corruption laws generally prohibit companies and their intermediaries from making improper payments or providing anything of value to wrongfully influence foreign government officials for the purpose of obtaining or retaining business or obtaining an unfair advantage, and generally require companies to maintain accurate books and records and internal controls, including at foreign controlled subsidiaries. Our internal policies provide for compliance with all applicable anti-corruption laws for both us and for our joint venture operations. Our continued operation and expansion outside the U.S., including in developing countries, could increase the risk of such violations in the future. Despite our training and compliance programs, our internal control policies and procedures may not always protect us from unauthorized, reckless or criminal acts committed by our employees, agents or joint venture partners.

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

With respect to our existing joint ventures, any differences in views among the joint venture participants may result in delayed decisions or in failures to agree on major issues. We also cannot control the actions of our joint venture partners, including any nonperformance, default or bankruptcy of our joint venture partners. As a result, we may be unable to control the quality of products produced by the joint ventures or achieve consistency of product quality as compared with our other operations. In addition to net sales and market share, this may have a material negative impact on our brand and how it is perceived thereafter. Moreover, if our partners also fail to invest in the joint venture in the manner that is anticipated or otherwise fail to meet their contractual obligations, the joint ventures may be unable to adequately perform and conduct their respective operations, requiring us to make additional investments or perform additional services to ensure the adequate performance and delivery of products and/or services to the joint ventures' customers, which could have a material adverse effect on our business, financial condition, results of operations and cash flows.

We may not be able to successfully expand into new products.

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

We continue to invest in our initiatives. If we fail to implement these initiatives as expected, our business, financial condition, and results of operations could be adversely affected.

Our financial performance and future growth depend on our management's ability to successfully implement our initiatives. Our operational initiatives are focused on capacity expansion, automation, safety, order management and transportation. Automation in our plants will allow for production efficiency and improved safety for plant personnel. Any failure to successfully implement these initiatives and related strategies could adversely affect our business, financial condition, and results of operations, including increases in our severance and impairment charges.

Increased fuel and energy prices, and our inability to obtain sufficient quantities of fuel to operate our in-house delivery fleet.

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

Internally manufacturing our products at our own facilities subjects our business to risks associated with manufacturing processes.

We internally manufacture our own products at our facilities with substantial fixed costs. While we maintain insurance covering our manufacturing and production facilities and have significant flexibility to manufacture and ship our own products from various facilities, a catastrophic loss of the use of certain of our facilities due to accident, fire, explosion, labor issues, weather conditions, pandemics, other natural disaster or otherwise, whether short or long-term, could have a material adverse effect on our business, financial condition, results of operations and cash flows. Our business interruption insurance may not be sufficient to offset the lost revenues or increased costs that we may experience during a disruption of our operations.

Unexpected failures of our equipment and machinery may result in production delays, revenue loss and significant repair costs, injuries to our employees, and customer claims. Any interruption in production capability may limit our ability to supply enough products to customers and may require us to make large capital expenditures to remedy the situation, which could have a negative impact on our profitability and cash flows. Increasing manufacturing capacity requires successful execution of capital projects, including adding, upgrading and replacing equipment.

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

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

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

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

18

Table of Contents

Advanced Drainage Systems, Inc.

against these lawsuits and proceedings may involve significant expense and diversion of management's attention and resources from other matters.

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

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

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

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

Interruptions in the proper functioning of information technology systems could disrupt operations and cause unanticipated increases in costs, decreases in revenues, or both. The implementation of our technology initiatives could disrupt our operations in the near term, and our technology initiatives might not provide the anticipated benefits or might fail.

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

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

We have made, and will continue to make, significant investments in technology. Our technology initiatives are designed to provide our customers a better order management and fulfillment experience, streamline our manufacturing operations and improve the quality of our internal control environment. The cost and potential problems and interruptions associated with the implementation of our technology initiatives could disrupt or reduce the efficiency of our operations in the near term. In addition, our new or upgraded technology might not provide the anticipated benefits, take longer than expected to realize the anticipated benefits or might fail altogether. The occurrence of such issues could have a material adverse effect on our business financial condition and results of operations.

Cybersecurity attacks may threaten our confidential information, disrupt operations and result in harm to our reputation and adversely impact our business and financial performance.

In the conduct of our business, we collect, use, transmit and store data on information systems, which are vulnerable to

disruption and an increasing threat of continually evolving cybersecurity risks. Cybersecurity attacks across industries are increasing in sophistication and frequency and may range from uncoordinated individual attempts to targeted measures. These attacks include but are not limited to, malicious software or viruses, including "ransomware" attempts to gain unauthorized access to, or otherwise disrupt, our information systems, attempts to gain unauthorized access to business, proprietary or other confidential information, and other electronic security breaches that could lead to disruptions in critical systems, unauthorized release of confidential or otherwise protected information and corruption of data. Cybersecurity failures may be caused by employee error, malfeasance, other corporate or governmental actors, system errors or vulnerabilities, including vulnerabilities of our vendors, suppliers, and their products.

While we have been subject to cybersecurity attacks in the past, that (based on information known to date) did not have a material impact on our financial condition or results of operations, we may experience such attacks in the future, potentially with more frequency or sophistication which may have a material impact on our financial condition or results of operations. The occurrence of any of these events could adversely affect our reputation and could result in litigation, regulatory action, financial loss, project delay claims and increased costs and operational consequences of implementing further data protection systems.

Failures of our IT systems as a result of cybersecurity attacks or other disruptions could result in a breach of critical operational or financial controls and lead to a disruption of our operations, commercial activities or financial processes. Cybersecurity attacks or other disruptions impacting significant customers and/or suppliers could also lead to a disruption of our operations. Despite our attempts to safeguard our systems and mitigate potential risks, there is no assurance that such actions will be sufficient to prevent cyberattacks or security breaches that manipulate or improperly use our systems or networks, compromise confidential or otherwise protected information, destroy or corrupt data, or otherwise disrupt our operations. The occurrence of such events could have a material adverse effect on our business financial condition and results of operations.

All of these risks are also applicable where we rely on outside vendors to provide services. We are dependent on third-party vendors to operate secure and reliable systems which may include data transfers over the internet. Any events which deny us use of vital operating or information systems may seriously disrupt our normal business operations. Additionally, our key partners, distributors or suppliers could experience a compromise of their information security due to a cybersecurity attack, which may have an impact on our business and financial performance.

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

To be successful, we must attract, train and retain a large number of highly qualified employees while controlling related labor costs. Our ability to control labor costs is subject to numerous external factors, including prevailing wage rates and health and other insurance costs. There is no assurance that we will be able to attract or retain highly qualified employees in the future, including, those employed by companies we acquire. None of our domestic employees are currently covered by collective bargaining or other similar labor agreements. However, if a number of our employees were to unionize, the effect on us may be negative.

In addition, our business results of operations depend largely upon our chief executive officer and senior management team as well as our plant managers and sales personnel, including those of companies acquired, and their experience, knowledge of local market dynamics and specifications and long-standing customer relationships. Our inability to retain or hire qualified plant managers or sales personnel at economically reasonable compensation levels would restrict our ability to grow our business, limit our ability to continue to successfully operate our business and result in lower operating results and profitability.

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

Our ability to compete effectively depends, in part, upon our ability to protect and preserve proprietary aspects of our intellectual property through a combination of patent, trademark, copyright and trade secret laws, as well as licensing agreements and third-party nondisclosure and assignment agreements. Because of the differences in foreign trademark, patent and other laws concerning proprietary rights, our intellectual property rights may not receive the same degree of protection in foreign countries as they would in the U.S. Our failure to obtain or maintain adequate protection of our

20

Table of Contents

Advanced Drainage Systems, Inc.

intellectual property rights for any reason could have a material adverse effect on our business, results of operations and financial condition.

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

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

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

Risks Relating to Our Indebtedness

Our level of indebtedness could adversely affect our business, financial conditions or results of operations and prevent us from fulfilling our obligations under the agreements governing the terms of our indebtedness.

Our indebtedness could have risks. For example, it could:

•make it more difficult for us to satisfy our obligations with respect to the Company's existing 5.0% senior notes due 2027 (the "Senior Notes") and our Senior Secured Credit Facility;

•increase our vulnerability to and compromise our flexibility to plan for, or react to, general adverse economic, industry or competitive conditions, including interest rate fluctuations, because a portion of our borrowings will be at variable rates of interest;

•cause us to be unable to meet the financial covenants contained in our debt agreements, or to generate cash sufficient to make required debt payments, which circumstances would have the potential of accelerating the maturity of some or all of our outstanding indebtedness;

•require us to dedicate a substantial portion of our cash flow from operations to payments on our indebtedness, thereby reducing the availability of our cash flow to fund working capital, capital expenditures, acquisitions, joint ventures and investments and other general corporate purposes, that could improve our competitive position, results of operations or share price;

•require us to sell debt or equity securities or to sell some of our core assets, possibly on unfavorable terms, to meet payment obligations;

•place us at a competitive disadvantage compared to our competitors that do not have the same level of indebtedness as we do and competitors that may be in a more favorable position to access additional capital resources;

•limit our ability to execute business development and acquisition activities to support our strategies;

•limit our ability to obtain additional indebtedness or equity due to applicable financial and restrictive covenants in our debt agreements; and

•limit our ability to refinance our indebtedness on more favorable terms.

We expect to pay principal and interest on current and future debt from cash provided by operating activities. Therefore, our ability to meet these payment obligations will depend on future financial performance and cash availability. If our cash flow and capital resources are insufficient to fund our debt obligations, we may be forced to reduce or delay expansion plans and capital expenditures, limit payment of dividends, sell material assets or operations, obtain additional capital or restructure our debt.

Risks Relating to Our Common Stock

Future sales of shares by existing stockholders, including shares of our common stock held in our newly formed KSOP, could cause our stock price to decline.

Sales of substantial amounts of our common stock in the public market, or the perception that these sales could occur, could cause the market price of our common stock to decline. On April 11, 2022, our employee stock ownership plan ("ESOP"), which was merged into our existing 401(k) retirement plan effective April 1, 2022 (the "KSOP"), completed the conversion of all 15.6 million outstanding shares of our preferred stock held by the ESOP, and then by the KSOP, on March 31, 2022, into 12.0 million shares of our common stock, in accordance with the conversion terms of our preferred stock. All of these shares will be eligible for future sale, either by the KSOP trustee or by KSOP participants subject to the limitation of Rule 144.

Based on shares outstanding as of May 10, 2022, we have 84.4 million outstanding shares of common stock, including 0.2 million outstanding shares of our restricted stock, a significant portion of which are freely tradeable without restriction under the Securities Act of 1933, as amended, ("Securities Act") unless held by "affiliates," as that term is defined in Rule 144 under the Securities Act. As of March 31, 2022, there were stock options outstanding to purchase a total of approximately 1.2 million shares of our common stock. In addition, approximately 2.6 million shares of common stock are available for grant under our 2017 Omnibus Plan.

Certain of our significant stockholders may distribute shares that they hold to their investors who themselves may then sell into the public market. Such sales may not be subject to the volume, manner of sale, holding period and other limitations of Rule 144 of the Securities Act ("Rule 144"). As resale restrictions end, the market price of our common stock could decline if the holders of those shares sell them or are perceived by the market as intending to sell them.

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

Our directors, officers and principal stockholders have significant voting power and may take actions that may not be in the best interests of our other stockholders. The trustee of our KSOP has certain limited powers to vote a large block of shares on matters presented to stockholders for approval.

As of May 10, 2022, our directors, officers and principal stockholders and their affiliates collectively own approximately 14% of our outstanding shares of common stock. Additionally, our newly formed KSOP holds shares of common stock that KSOP participants with ESOP accounts are entitled to vote on a one-for-one basis on any matter requiring the vote or consent of our stockholders. Thus, the collective voting power of our directors, officers and principal stockholders and their affiliates as of May 10, 2022 is approximately 29%, inclusive of the outstanding shares of common stock held by the KSOP. As a result, these stockholders, if they act together, may be able to control our management and affairs and most matters requiring stockholder approval, including the election of directors and approval of significant corporate transactions. This concentration of ownership may have the effect of delaying or preventing a change of control and might adversely affect the market price of our common stock. This concentration of ownership may not be in the best interests of our other stockholders.

In general, the KSOP trustee votes the shares of common stock held by the KSOP as directed by the KSOP's participants with ESOP accounts. Consequently, the KSOP trustee has the ability to vote a significant block of shares on certain matters presented to stockholders for approval. Each participant with an ESOP account in the KSOP may direct the KSOP trustee on how to vote the shares of common stock allocated to the participant's ESOP accounts in the KSOP; and the KSOP trustee may vote any shares of common stock for which no participant instructions were received in the same proportion as the allocated stock for which participants' voting instructions have been received is voted.

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

Our amended and restated certificate of incorporation and amended and restated bylaws include a number of provisions that may discourage, delay or prevent a change in our management or control over us that stockholders may consider favorable. For example, our amended and restated certificate of incorporation and amended and restated bylaws, each as further amended authorize the issuance of "blank check" preferred stock that could be issued by our board of directors to

22

Table of Contents

Advanced Drainage Systems, Inc.

thwart a takeover attempt; maintain a classified board of directors, for the next three years, until such time that our declassified board structure is fully implemented at the 2023 annual meeting of stockholders; provide that vacancies on our board of directors, including newly-created directorships, may be filled only by a majority vote of directors then in office; prohibit stockholders from calling special meetings of stockholders; prohibit stockholder action by written consent, thereby requiring all actions to be taken at a meeting of the stockholders; do not give the holders of our common stock cumulative voting rights with respect to the election of directors, which means that the holders of a majority of our outstanding shares of common stock can elect all directors standing for election; establish advance notice requirements for nominations for election to our board of directors or for proposing matters that can be acted upon by stockholders at stockholder meetings; require a super-majority stockholders vote of 75% to approve any reorganization, recapitalization, share exchange, share reclassification, consolidation, merger, conversion or sale of all or substantially all assets to which we are a party that is not approved by the affirmative vote of at least 75% of the members of our board of directors; and require the approval of holders of a majority of the outstanding shares of our voting common stock to amend the bylaws and at least 75% of the outstanding shares of our voting common stock to amend certain provisions of the certificate of incorporation.

Any provision of our amended and restated certificate of incorporation, amended and restated bylaws or Delaware General Corporation Law that has the effect of delaying or deterring a change in control could limit the opportunity for our stockholders to receive a premium for their shares of our common stock, and could also affect the price that some investors are willing to pay for our common stock.

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

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

General Risk Factors

As a publicly-traded manufacturing company, we are subject to a variety of risks in addition to the risks described above, each of which could adversely affect our financial position, results of operations or cash flows.

These risks include but are not limited to:

•taxation by multiple jurisdictions and the impact of such taxation on the effective tax rate and the amount of taxes paid;

•material liabilities under our self-insured programs for workers' compensation, automobile and product/general liability coverage as well as health coverage to our employees;

•fluctuations in our effective tax rate, including from the Tax Cuts and Jobs Act of 2017, the Coronavirus Aid, Relief, and Economic Security ("CARES") Act and any future tax legislation;

•new or modified legislation related to health care;

•the review of potential weaknesses or deficiencies in the Company's disclosure controls and procedures, and discovering further weaknesses of which we are not currently aware or which have not been detected;

•we cannot assure our stockholders that an active market for shares of our common stock can be sustained and the market price of our common stock may be volatile and could decline in the future; and

•failure to meet the expectations of investors, including as a result of factors beyond our control.

Overview

We are the leading manufacturer of high performance thermoplastic corrugated pipe, providing a comprehensive suite of water management products and superior drainage solutions for use in the underground construction and infrastructure marketplace. Our innovative products are used across a broad range of end markets and applications, including non-residential, residential, agriculture and infrastructure applications. We have established a leading position in many of these end markets by leveraging our national sales and distribution platform, our overall product breadth and scale and our manufacturing excellence. In the United States, our national footprint combined with our strong local presence and broad product offering make us the leader in an otherwise highly fragmented sector comprised of many smaller competitors. With the acquisition of Infiltrator in the second quarter of fiscal 2020, we are now a leading provider of plastic leachfield chambers, septic tanks and accessories for use primarily in residential applications.

Impact of COVID-19

In March 2020, the World Health Organization categorized the novel coronavirus ("COVID-19") as a pandemic, and it continues to spread throughout the United States and globally. The COVID-19 pandemic has resulted, and is likely to continue to result, in significant economic disruptions and may have an adverse effect on our business. Significant uncertainty exists concerning the magnitude of the impact and duration of the COVID-19 pandemic.

Key Factors Affecting Our Results of Operations

Product Demand - There are numerous factors that influence demand for our products. Our businesses are cyclical in nature and sensitive to general economic conditions, primarily in the United States, Canada, Mexico and South America. The non-residential, residential, agricultural and infrastructure markets we serve are affected by the availability of credit, lending practices, interest rates and unemployment rates. Demand for new homes, farm income, commercial development and highway infrastructure spending have a direct impact on our financial condition and results of operations. Accordingly, the following factors may have a direct impact on our business in the markets in which our products are sold:

•the strength of the economy;

•the amount and type of non-residential and residential construction;

•funding for infrastructure spending;

•farm income and agricultural land values;

•inventory of improved housing lots;

•changes in raw material prices;

•the availability and cost of credit;

•non-residential occupancy rates;

•commodity prices; and

•demographic factors such as population growth and household formation.

Product Pricing - The price of our products is impacted by competitive pricing dynamics in our industry as well as by raw material input costs. Our industry is highly competitive and the sales prices for our products may vary based on the sales policies of our competitors. Raw material costs represent a significant portion of the cost of goods sold for our products. We aim to increase our product selling prices in order to cover raw material price increases, but the inability to do so could

impact our profitability. Movements in raw material, logistics or other overhead costs and resulting changes in the selling prices may also impact changes in period-to-period comparisons of net sales.

Material Conversion - Our HDPE and PP pipe, plastic leachfield chambers, septic tanks and related water management product lines compete with other manufacturers of corrugated polyethylene pipe as well as manufacturers of alternative products made with traditional materials, such as concrete, steel and PVC. Our net sales are driven by market trends, including the continued increase in adoption of thermoplastic corrugated pipe products as a replacement for traditional materials. Thermoplastic corrugated pipe is generally lighter, more durable, more cost effective and easier to install than comparable products made from traditional materials. We believe customers will continue to acknowledge the superior attributes and compelling value proposition of our thermoplastic products and expanded regulatory approvals allow for their use in new markets and geographies. In addition, we believe that PP pipe products will also help accelerate conversion given the additional applications for which our PP pipe products can be used.

We believe the adoption of HDPE and PP pipe outside of the United States is still in its early stages and represents a significant opportunity for us to continue to increase the conversion to our products from traditional products in these markets, including Canada, Mexico and South America where we operate.

Growth in Allied Products & Other - Our Allied Products & Other include storm and septic chambers, PVC drainage structures, fittings, stormwater filters and water separators. These products complement our pipe product lines and allow us to offer a comprehensive water management solution to our customers and drive organic growth. Our leading market position in pipe products allows us to cross-sell Allied Products & Other effectively. Our comprehensive offering of Allied Products & Other also helps us increase pipe sales in certain markets. Our Allied Products & Other are less sensitive to increases in resin prices since resin prices represent a smaller percentage of the cost for Allied Products & Other.

Our leading position in the pipe market has allowed us to increase organic growth of our Allied Products & Other. We also expect to expand our Allied Product offerings through acquisitions.

Raw Material Costs - Our raw material cost and product selling prices fluctuate with changes in the price of resins utilized in production. We actively manage our resin purchases and pass fluctuations in the cost of resin through to our customers, where possible, in order to maintain our profitability. Fluctuations in the price of crude oil and natural gas prices may impact the cost of resin. In addition, changes in and disruptions to existing ethylene or polyethylene capacities could also significantly increase resin prices, often within a short period of time, even if crude oil and natural gas prices remain low. Our ability to pass through raw material price increases to our customers may, in some cases, lag the increase in our costs of goods sold. Sharp rises in raw material prices over a short period of time have historically occurred with a significant supply disruption (hurricanes or fires at petrochemical facilities), which may increase prices to levels that cannot be fully passed through to customers due to pricing of competing products made from different raw materials or the anticipated length of time the raw material pricing will stay elevated. For more information regarding risks relating to our raw material costs, see "Item 1A. Risk Factors - Risks Relating to Our Business."

We currently purchase in excess of 1.3 billion pounds of virgin and recycled resin annually from approximately 500 suppliers in North America. As a high-volume buyer of resin, we are able to achieve economies of scale to negotiate favorable terms and pricing. Our purchasing strategies differ based on the material (virgin resin versus recycled material) ordered for delivery to our production locations. The price movements of the different materials also vary, resulting in the need to use a number of strategies to reduce volatility.

In order to reduce the volatility of raw material costs in the future, our raw material strategies for managing our costs include the following:

•increasing the use of less price-volatile recycled HDPE resin in our pipe products in place of virgin resin while meeting or exceeding industry standards;

•internally processing an increasing percentage of our recycled HDPE resin in order to closely monitor quality and minimize costs;

•managing a resin price risk program that may entail both physical fixed price and volume contracts; and

•maintaining supply agreements with our major resin suppliers that provide multi-year terms and volumes that are in excess of our projected consumption.

We also consume a large amount of energy and other petroleum products in our operations, including the electricity we use in our manufacturing process as well as the diesel fuel consumed in delivering a significant volume of products to our

29

Table of Contents

Advanced Drainage Systems, Inc.

customers through our in-house fleet. As a result, our operating profit also depends upon our ability to manage the cost of the energy and fuel we require, as well as our ability to pass through increased prices or surcharges to our customers.

Seasonality - Our operating results are impacted by seasonality. Historically, sales of our products have been higher in the first and second quarters of each fiscal year due to favorable weather and longer daylight conditions accelerating construction project activity during these periods while fourth quarter results are impacted by the timing of spring in the northern United States and Canada. Seasonal variations in operating results may also be significantly impacted by inclement weather conditions, such as cold or wet weather, which can delay projects, resulting in decreased net sales for one or more quarters, but we believe that these delayed projects generally result in increased net sales during subsequent quarters.

In the non-residential, residential and infrastructure markets in the northern United States and Canada, the construction season typically begins to gain momentum in late March and lasts through November, before winter sets in, significantly slowing the construction markets. In the southern and western United States, Mexico, Central America and South America, the construction markets are less seasonal. The agricultural drainage market is concentrated in the early spring just prior to planting and in the fall just after crops are harvested prior to freezing of the ground in winter.

Currency Exchange Rates - Although we sell and manufacture our products in many countries, our sales and production costs are primarily denominated in U.S. dollars. We have wholly-owned facilities in Canada, the Netherlands and joint venture facilities in Mexico, Chile, Brazil, Argentina, Colombia and Peru. The functional currencies in the areas in which we have wholly-owned facilities and joint venture facilities other than the U.S. dollar are the Canadian dollar, Euro, Mexican peso, Chilean peso, Brazilian real and Colombian peso. From time to time, we use derivatives to reduce our exposure to currency fluctuations.

Executive Summary of Our Fiscal Year 2022 Results

Fiscal Year 2022 Results

•Net sales increased 39.7% to $2.8 billion

•Net income increased to $275.0 million, compared to net income of $226.1 million in the prior year

•Adjusted EBITDA increased 19.2% to $676.0 million

•Cash provided by operating activities decreased 39.2% to $274.9 million

•Free cash flow decreased 66.3% to $125.8 million

Net sales increased $786.5 million, or 39.7%, to $2,769.3 million, as compared to $1,982.8 million in the prior year. Domestic pipe sales increased $496.0 million, or 46.8%, to $1,555.2 million. Domestic allied products & other sales increased $126.9 million, or 28.7%, to $569.4 million. Infiltrator sales increased $154.1 million, or 38.7%, to $551.9 million. These increases were driven by strong sales growth in both the U.S. construction and agriculture end markets. International sales increased $59.9 million, or 36.3%, to $224.7 million, driven by double-digit sales growth in the Canadian, Mexican and Exports businesses.

Gross profit increased $110.3 million, or 16.0%, to $800.4 million as compared to $690.1 million in the prior year. The increase is primarily due an increase in sales volume and favorable pricing on pipe, onsite septic and allied products. These increases were partially offset by inflationary cost pressure on materials, transportation and labor, as well as an increase in the use of third-party logistics services. Labor shortages and absenteeism related to COVID-19 remain a challenge in both manufacturing and transportation operations. In addition, the Company recorded $19.2 million of non-cash, stock-based compensation expense in Cost of goods sold - ESOP acceleration and special dividend compensation expense.

Adjusted EBITDA, a non-GAAP financial measure, increased $109.1 million, or 19.2%, to $676.0 million, as compared to $567.0 million in the prior year. The increase is primarily due to the factors mentioned above. As a percentage of net sales, Adjusted EBITDA was 24.4% as compared to 28.6% in the prior year.

Description of our Segments

We operate our business in three distinct reportable segments: "Pipe", "International" and "Infiltrator." "Allied Products & Other" represents our Allied Products and all other business segments.

We generate a greater proportion of our net sales and gross profit in our Pipe segment, which consists of Pipe product sales in all regions of the United States. We expect the percentage of total net sales and gross profit derived from our other

30

segments to continue to increase in future periods as we continue to expand non-Pipe product and our international presence. See "Note 18. Business Segment Information," to our audited consolidated financial statements included in "Item 8. Financial Statements and Supplementary Data" of this Form 10-K.

Pipe - Our Pipe segment manufactures and markets high performance thermoplastic corrugated pipe throughout the United States. We maintain and serve these markets through product distribution relationships with many of the largest national and independent waterworks distributors, buying groups and co-ops, major national retailers as well as an extensive network of hundreds of small to medium-sized distributors across the United States.

Infiltrator - Infiltrator is a leading national provider of plastic leachfield chambers and systems, septic tanks and accessories, primarily for use in residential applications. Infiltrator products are used in onsite septic wastewater treatment systems in the United States and Canada.

International - Our International segment manufactures and markets products in regions outside of the United States, with a strategy focused on our owned facilities in Canada and those markets serviced through our joint ventures in Mexico and South America. Pipe manufactured in these countries is primarily sold into the same region. Our joint venture strategy has provided us with local and regional access to new markets. The unconsolidated sales of the South American Joint Venture were $61.6 million, $45.6 million, and $52.5 million, in fiscal 2022, 2021, and 2020, respectively.

Allied Products & Other - Our other operating segments manufacture a range of Allied Products & Other that are complementary to our Pipe products. Our Allied Products & Other offer adjacent technologies to our core Pipe offering, presenting a complete drainage solution for our clients and customers.

Our consolidated net sales for the fiscal year ended March 31, 2022 increased by $786.5 million, or 39.7%, compared to fiscal 2021. The increase in net sales was primarily a result of growth in our domestic Pipe segment along with both the Infiltrator and International segments.

Our Pipe segment experienced growth primarily through improved pricing/mix of products sold. Infiltrator achieved growth through improved price/mix of products sold and higher volumes associated with the residential market. The increase in our International segment was driven by improved price/mix of products sold in the Canadian and Mexican businesses. Growth in Allied Products & Other was driven mainly by improved price/mix of products offerings.

administrative expenses is the result of increased headcount to support business growth along with higher spend in various areas impacted last year by COVID-19 including travel and entertainment expenses and transaction costs.

Selling, general and administrative - ESOP acceleration and special dividend compensation - In fiscal 2022, ESOP acceleration compensation expense of $11.3 million was allocated to selling, general and administrative expenses which did not occur in fiscal 2021.

Loss on disposal of assets and costs from exit and disposal activities - The change in Loss on disposal of assets and costs from exit and disposal activities is primarily due to asset disposals.

Intangible amortization - Intangible amortization decreased by $9.7 million primarily due the accelerated method of amortization for customer relationships.

Interest expense - Interest expense decreased $2.1 million for the fiscal year ended March 31, 2022 compared to the same period in fiscal 2021. The decrease was primarily due to decreased average debt levels.

Derivative gains and other income, net - Derivative gains and other income, net increased by $1.7 million or the fiscal year ended March 31, 2022 compared to the same period in fiscal 2021.

Income tax expense - The following table presents the effective tax rates for thefiscal years presented:

	2022	2021
Effective tax rate	28.7	%	27.7	%

The increase in the effective tax rate was primarily due to stock appreciation from the ESOP shares allocated during fiscal year 2022. See "Note 15. Income Taxes" for additional information.

Equity in net income of unconsolidated affiliates - The Equity in net income of unconsolidated affiliates increased for the fiscal year ended March 31, 2022 compared to the same period in fiscal 2021 due to an increase in the current period income at our South American Joint Venture.

Net income attributable to noncontrolling interest - Net income attributable to noncontrolling interest increased for the fiscal year ended March 31, 2022 due to increased net income at our ADS Mexicana joint venture.

The discussion of our results of operations for the fiscal year ended March 31, 2021 compared with the fiscal year ended March 31, 2020 can be found in our fiscal 2021 Form 10-K. See "Item 7. Management's Discussion and Analysis of Financial Discussion and Results of Operations" in our fiscal 2021 Form 10-K for further information on our prior period results of operations.

Non-GAAP Financial Measures

EBITDA, Adjusted EBITDA and Adjusted EBITDA Margin - EBITDA, Adjusted EBITDA and Adjusted EBITDA Margin, non-GAAP financial measures, have been presented in this Annual Report on Form 10-K as supplemental adjusted EBITDA as net income before interest, income taxes, depreciation and amortization, stock-based compensation expense, non-cash charges and certain other gains and expenses. We calculate Adjusted EBITDA Margin as Adjusted EBITDA divided by net sales.

EBITDA, Adjusted EBITDA and Adjusted EBITDA Margin are included in this Annual Report on Form 10-K because they are key metrics used by management and our Board of Directors to assess our financial performance. EBITDA, Adjusted EBITDA and Adjusted EBITDA Margin are frequently used by analysts, investors and other interested parties to evaluate companies in our industry. In addition to covenant compliance and executive performance evaluations, we use EBITDA, Adjusted EBITDA and Adjusted EBITDA Margin to supplement GAAP measures of performance to evaluate the effectiveness of our business strategies, to make budgeting decisions and to compare our performance against that of other peer companies using similar measures.

EBITDA, Adjusted EBITDA and Adjusted EBITDA Margin are not GAAP measures of our financial performance and should not be considered as alternatives to net income as measures of financial performance or cash flows from operations or any other performance measure derived in accordance with GAAP, and it should not be construed as an inference that

33

Table of Contents

our future results will be unaffected by unusual or non-recurring items. EBITDA, Adjusted EBITDA and Adjusted EBITDA Margin contain certain other limitations, including the failure to reflect our cash expenditures, cash requirements for working capital needs and cash costs to replace assets being depreciated and amortized. In evaluating EBITDA, Adjusted EBITDA and Adjusted EBITDA Margin, you should be aware that in the future we will incur expenses that are the same as or similar to some of the adjustments in this presentation, such as stock-based compensation expense, derivative fair value adjustments, and foreign currency transaction losses. Management compensates for these limitations by relying on our GAAP results in addition to using EBITDA, Adjusted EBITDA and Adjusted EBITDA Margin on a supplemental basis. Our measure of EBITDA, Adjusted EBITDA and Adjusted EBITDA Margin are not necessarily comparable to other similarly titled captions of other companies due to different methods of calculation.

In the fourth quarter of fiscal 2022, the approximately 0.3 million remaining unallocated shares of Preferred Stock were allocated on March 31, 2022 after repayment of the ESOP loan. See "Note 13. Employee Benefit Plans" for additional information. In the first quarter of fiscal 2020, the Company paid a special dividend of $1.00 per share. The dividend was used to pay back a portion of the ESOP loan resulting in $246.8 million in additional stock-based compensation. See "Note 16. Net Income Per Share and Stockholders' Equity" for additional information.

Liquidity and Capital Resources

Historically we have funded our operations through internally generated cash flow supplemented by debt financings, equity issuance and finance and operating leases. These sources have been sufficient historically to fund our primary liquidity requirements, including working capital, capital expenditures, debt service and dividend payments for our convertible preferred stock and common stock. From time to time, we may explore additional financing methods and other means to raise capital. There can be no assurance that any additional financing will be available to us on acceptable terms or at all.

In addition to the available liquidity above, we have the ability to borrow up to $1.3 billion under our Term Loan Facility, subject to leverage ratio restrictions.

As of March 31, 2022, we had $12.9 million in cash that was held by our foreign subsidiaries, including $5.4 million held by our Canadian subsidiaries. We continue to evaluate our strategy regarding foreign cash, but our earnings in foreign subsidiaries still remain indefinitely reinvested, except for Canada. See "Note 15. Income Taxes" for additional discussion of our plans to repatriate earnings from Canada.

Free Cash Flow - Free cash flow is a non-GAAP financial measure that comprises cash flow from operations less capital expenditures. Free cash flow is a measure used by management and our Board of Directors to assess our ability to generate cash. Accordingly, free cash flow has been presented in this Annual Report on Form 10-K as a supplemental measure of liquidity that is not required by, or presented in accordance with GAAP, because management believes that free cash flow provides useful information to investors and others in understanding and evaluating our ability to generate cash flow from operations after capital expenditures.

Free cash flow is not a GAAP measure of our liquidity and should not be considered as an alternative to cash flow from operating activities as a measure of liquidity or any other liquidity measure derived in accordance with GAAP. Our measure of free cash flow is not necessarily comparable to other similarly titled captions of other companies due to different methods of calculation.

(Amounts in thousands)	2022		2021		2020
Cash flow from operating activities	$	274,888	$	452,216	$	306,189
Capital expenditures	(149,083)	(78,757)	(67,677)
Free cash flow	$	125,805		$	373,459		$	238,512

Working Capital and Cash Flows

Our use of cash in fiscal 2022, of $174.9 million, was predominantly driven by the $292.0 million in share repurchases net of incremental borrowings during fiscal 2022, offset by cash generated from operations in excess of investments in working capital and capital expenditures. Cash in fiscal 2021 increased by $20.8 million primarily from cash generated from operations net of payments on our Term Loan Facility and Revolving Credit Facility. During fiscal 2020, our net increase in cash amounted to $165.3 million. Our sources of funds in fiscal 2020 were primarily driven by borrowings under the Term Loan Facility, Senior Notes and Revolving Credit Facility, proceeds from our Common Stock Offering and

35

Table of Contents

Advanced Drainage Systems, Inc.

an increase in cash provided by operating activities. Our use of cash during fiscal 2020 was primarily related to the Acquisition and repayment of our previous debt arrangements.

As of March 31, 2022, we had $246.6 million in liquidity, including $20.1 million of cash, $226.5 million in borrowings available under our Revolving Credit Facility, excluding $9.2 million of outstanding letters of credit. We believe that our cash on hand, together with the availability of borrowings under our Revolving Credit Facility and cash generated from operations, will be sufficient to meet our working capital requirements, anticipated capital expenditures and scheduled interest payments on our indebtedness for at least the next twelve months.

Working Capital- Working capital is an indication of liquidity and potential need for short-term funding. We define working capital as current assets less current liabilities.

Working capital increased to $480.7 million as of March 31, 2022, from $424.7 million as of March 31, 2021, primarily due to the increases in inventory related to the inflationary cost of resin and increased quantities to support demand, as well as increased accounts receivable and accounts payable which increased consistent with the increase in net sales and inventory, offset by the use of cash during the fiscal year.

Working capital decreased to $424.7 million as of March 31, 2021, from $428.0 million as of March 31, 2020, primarily due to an increase in accounts payable, due to improved payment terms, offset by increased accounts receivable and inventory due to increased sales.

Operating Cash Flows - During fiscal 2022, cash provided by operating activities was $274.9 million. Cash flow from operating activities in fiscal 2022 was primarily driven by operating income offset by investments in working capital.

During fiscal 2021, cash provided by operating activities was $452.2 million as compared with cash provided by operating activities of $306.2 million for fiscal 2020. Cash flow from operating activities during fiscal 2021 was primarily impacted by increased income from continuing operations and improvements in payment terms on accounts payable.

During fiscal 2020, cash provided by operating activities was $306.2 million. Cash flow from operating activities during fiscal 2020 was primarily impacted by changes in working capital, including improved collections from accounts receivable, faster inventory turns and extension of terms of our accounts payable.

Investing Cash Flows - During fiscal 2022, cash used for investing activities was $198.8 million. The increase in cash used for investing cash flows was primarily due to elevated capital expenditures and the acquisition of Jet Polymer Recycling. Our capital expenditures in fiscal 2022 were used primarily to support growth, but also to support our recycled resin and technology improvement initiatives.

During fiscal 2021, cash used for investing activities was $77.9 million. The decrease in cash used for investing activities was primarily due to the acquisition of Infiltrator in fiscal 2020. Capital expenditures was $78.8 million compared to $67.7 million in fiscal 2020. Our capital expenditures in fiscal 2021 were used primarily to support facility expansions, equipment replacements, our recycled resin and technology improvement initiatives.

During fiscal 2020, cash used for investing activities was $1,150.5 million. The cash used for investing activities was primarily due to the acquisition of Infiltrator, net of cash acquired, in fiscal 2020. Our capital expenditures in fiscal 2020 of $67.7 million were used primarily to support facility improvements, equipment replacements, our recycled resin and operating efficiency initiatives and technology.

We currently anticipate that we will make capital expenditures of approximately $150 to $180 million in fiscal 2023 to focus on growth and productivity through increasing our manufacturing capacity and investing in automation. Such capital expenditures are expected to be financed using funds generated by operations. We had approximately $80 million of open orders through purchase commitments as of March 31, 2022.

Financing Cash Flows - During fiscal 2022, cash used in financing activities was $251.1 million. During fiscal 2022, ADS repurchased shares for $292.0 million.

During fiscal 2021, cash used in financing activities was $354.5 million, due to payments on the Term Loan Facility of $207.0 million and the Revolving Credit Facility of $100.0 million. In addition, we made dividend payments of $32.1 million and $21.5 million on our finance lease obligations.

During fiscal 2020, cash provided by financing activities was $1,011.6 million, due to the new Term Loan Facility, Senior Notes and Common Stock Offering. These cash inflows were offset by the repayment of the PNC Credit Agreement and Prudential Senior Notes, the special and quarterly dividend payments of $92.1 million and payments on our finance lease obligations of $27.1 million.

Employee Stock Ownership Plan ("ESOP")

The Company established the Advanced Drainage Systems, Inc. ESOP (the "ESOP" or the "Plan") effective April 1, 1993 to enable eligible employees to acquire stock ownership in ADS in the form of redeemable convertible preferred shares. The Plan was funded by an existing tax-qualified profit-sharing retirement plan, as well as a 30-year term loan from ADS. Within 30 days following the repayment of the ESOP loan, which occurred in March 2022, the ESOP committee directed the shares of redeemable convertible preferred stock owned by the ESOP to be converted into shares of the Company's common stock.

The Company was obligated to make contributions to the Plan, which, when aggregated with the Plan's dividends, equal the amount necessary to enable the Plan to make its regularly scheduled payments of principal and interest due on its term loan to ADS. Compensation expense was recognized based upon the average annual fair value of the shares during the period which ADS received payments on the term loan, and the number of ESOP shares allocated to participant accounts.

Following the repayment of the ESOP loan discussed above, the ESOP's conversion of redeemable convertible preferred stock into common stock will impact the Company's net income, net income per share and common shares outstanding as follows (with the outstanding shares of common stock being approximately 19% greater after conversion).

Impact on Net Income- Provided that the converted common stock do not qualify as participating securities, the Company will no longer be required to apply the two-class method to determine Net income per share once all of the redeemable convertible preferred stock is converted into common stock. After the preferred shares are fully allocated upon the repayment of the ESOP loan and all of the redeemable convertible preferred stock is converted into common stock, the Company will no longer incur the fair value of ESOP deferred compensation attributable to the shares of redeemable convertible preferred shares.

The impact of the ESOP on net income includes the fair value of ESOP deferred compensation attributable to the shares of redeemable convertible preferred stock allocated to employee ESOP accounts during the applicable period, which is a non-cash charge to our earnings and not deductible for income tax purposes. Additional ESOP compensation expense was recorded for the acceleration of the remaining loan payment in the fourth quarter of fiscal 2022 and the repayment of a significant portion of the ESOP loan, through the special dividend, in fiscal 2020.

ESOP acceleration and special dividend compensation	30,435	-	246,752

Financing Transactions

Bridge Credit Facility - On July 31, 2019, we entered into the Base Credit Agreement with Barclays Bank PLC, as administrative agent and the several lenders from time to time party thereto. The Base Credit Agreement provides for up to $1.3 billion as a Term Loan Facility, up to $350 million as a Revolving Facility, up to $50 million as an L/C Facility and up to $50 million, as a sublimit of the Revolving Facility.

On July 31, 2019, the Company borrowed under the Base Credit Agreement which was used to (i) finance the merger consideration paid in connection with the closing of the acquisition of Infiltrator by us which occurred on July 31, 2019 (the "Merger"), (ii) repay the total outstanding amount as of the closing date of the Merger under its credit agreements, (iii) repay outstanding amounts of existing indebtedness incurred by Infiltrator under its outstanding credit facility in effect prior to the Merger, and (iv) pay certain transaction fees and expenses associated with the Merger and the Base Credit Agreement.

New Senior Secured Credit Facility - On September 24, 2019, the joint lead arrangers informed the Company that the parties had successfully completed a syndication of the remaining balance of the Bridge Credit Facility. The Senior Secured Credit Facility provided for a Term Loan Facility with an initial aggregate amount of $700 million, up to $350 million as a Revolving Facility, and up to $50 million as a letter of credit facility, as a sublimit of the Revolving Facility.

The Term Loan Facility has an amortization feature equal to 1% of the original $700 million balance paid in equal quarterly installments commencing on January 1, 2020 and continuing on the first day of each consecutive April, July, October and January thereafter. To the extent not previously paid, all then-outstanding amounts under the Term Loan Facility are due and payable on the maturity date of the Term Loan Facility, which is September 26, 2026. Borrowings under the Revolving Facility are available beginning on the Closing Date and, to the extent not previously paid, all then-outstanding amounts under the Revolving Facility are due and payable on the maturity date of the Revolving Facility, which is September 29, 2024.

The Senior Secured Credit Facility includes customary representations, warranties, covenants and events of default.

At the option of the Company, borrowings under the Term Loan Facility and under the Revolving Facility (subject to certain limitations) bear interest at either a base rate (as determined pursuant to the Senior Secured Credit Facility) or at a Eurocurrency Rate, based on LIBOR (as defined in the Senior Secured Credit Facility), plus the applicable margin as set forth therein from time to time. In the case of the Revolving Facility, the applicable margin is based on the Company's consolidated senior secured net leverage ratio (as defined in the Senior Secured Credit Facility). All borrowings under the Term Loan Facility used to finance the merger consideration as described above initially bear interest at a Eurocurrency Rate (as defined in the Senior Secured Credit Facility).

The Company's obligations under the Credit Agreement have been secured by granting a first priority lien on substantially all of the Company's assets (subject to certain exceptions and limitations), and each of StormTech, LLC, Advanced Drainage of Ohio, Inc. and Infiltrator Water Technologies, LLC (collectively the "Guarantors") has agreed to guarantee the obligations of the Company under the Senior Secured Credit Facilityand to secure the obligations thereunder by granting a first priority lien in substantially all of such Guarantor's assets (subject to certain exceptions and limitations).

Senior Notes due 2027 - On September 23, 2019, the Company issued $350.0 million aggregate principal amount of its senior notes ("Senior Notes"), pursuant to the Indenture among the Company, the Guarantors and the trustee. The Senior Notes are guaranteed by each of the Company's present and future direct and indirect wholly owned domestic subsidiaries that is a guarantor under the Company's Senior Secured Credit Facility. The Senior Notes were offered and sold either to persons reasonably believed to be "qualified institutional buyers" pursuant to Rule 144A under the Securities Act of 1933 (the "Securities Act") or to persons outside the United States under Regulation S of the Securities Act.

Interest on the Senior Notes is payable semi-annually in cash in arrears on March 31 and September 30 of each year, commencing on March 31, 2020, at a rate of 5.000% per annum. The Senior Notes mature on September 30, 2027. The Company used the majority of the net proceeds from the offering of the Senior Notes for the repayment of $300.0 million of its outstanding borrowings under the Company's Bridge Credit Facility.

The Company may redeem the Senior Notes, in whole or in part, at any time on or after September 30, 2022 at established redemption prices. At any time prior to September 30, 2022, the Company may also redeem up to 40% of the Senior Notes with net cash proceeds of certain equity offerings at a redemption price equal to 105.000% of the principal amount of the Senior Notes to be redeemed, plus accrued and unpaid interest, if any, to, but excluding, the redemption date. In addition, at

38

Advanced Drainage Systems, Inc.

any time prior to September 30, 2022, the Company may redeem the Senior Notes, in whole or in part, at a redemption price equal to 100% of the principal amount of the Senior Notes to be redeemed, plus accrued and unpaid interest, if any, to, but excluding, the redemption date plus an applicable "make-whole" premium.

The Indenture contains customary events of default, including, among other things, payment default, failure to comply with covenants or agreements contained in the Indenture or the Senior Notes and certain provisions related to bankruptcy events. The Indenture also contains customary negative covenants.

Covenant Compliance

The Senior Secured Credit Facility requires, if the aggregate amount of outstanding exposure under the Revolving Facility exceeds $122.5 million at the end of any fiscal quarter, the Company to maintain a consolidated senior secured net leverage ratio (commencing with the fiscal quarter ending March 31, 2020) not to exceed 4.25 to 1.00 for any four consecutive fiscal quarter periods.

The Senior Secured Credit Facility also includes other covenants, including negative covenants that, subject to certain exceptions, limit the Company's and its restricted subsidiaries' (as defined in the Credit Agreement) ability to, among other things: (i) incur additional debt, including guarantees; (ii) create liens upon any of their property; (iii) enter into any merger, consolidation or amalgamation, liquidate, wind up or dissolve, or dispose of all or substantially all of their property or business; (iv) dispose of assets; (v) pay subordinated debt; (vi) make certain investments; (vii) enter into swap agreements; (viii) engage in transactions with affiliates; (ix) engage in new lines of business; (x) modify certain material contractual obligations, organizational documents, accounting policies or fiscal year; or (xi) create or permit restrictions on the ability of any subsidiary of any Loan Party (as defined in the Senior Secured Credit Facility) to pay dividends or make distributions to the Company or any of its subsidiaries.

The Senior Secured Credit Facility also contains customary provisions requiring the following mandatory prepayments (subject to certain exceptions and limitations): (i) annual prepayments (beginning with the fiscal year ending March 31, 2021) with a percentage of excess cash flow (as defined in the Senior Secured Credit Facility); (ii) 100% of the net cash proceeds from any non-ordinary course sale of assets and certain casualty or condemnation events; and (iii) 100% of the net cash proceeds of indebtedness not permitted to be incurred under the Senior Secured Credit Facility.

For further information, see "Note 11. Debt" to the Consolidated Financial Statements. We were in compliance with our debt covenants as of March 31, 2022.

Off-Balance Sheet Arrangements

We do not have any off-balance sheet arrangements, with the exception of the guarantee of 50% of certain debt of our unconsolidated South American Joint Venture, as further discussed in "Note 10. Related Party Transactions" of our Consolidated Financial Statements included in "Item 8. Financial Statements and Supplementary Data," of this Form 10-K. Our maximum potential obligation under this guarantee totals $11 million as of March 31, 2022. The maximum borrowing permitted under the South American Joint Venture's credit agreement is $22 million. As of March 31, 2022, our South American Joint Venture had approximately $9.9 million of outstanding debt subject to our guarantee, resulting in our guarantee of 50%, or $5.0 million, of that amount. We do not believe that this guarantee will have a current or future effect on our financial condition, results of operations, liquidity, or capital resources.

Critical Accounting Policies and Estimates

Our discussion and analysis of financial condition and results of operations are based on our consolidated financial statements, which have been prepared in accordance with GAAP. The preparation of the consolidated financial statements requires management to make estimates and judgments that affect the reported amounts in our consolidated financial statements and accompanying notes.

Certain of our accounting policies involve a higher degree of judgment and complexity in their application, and therefore, represent the critical accounting policies used in the preparation of our financial statements. If different assumptions or conditions were to prevail, the results could be materially different from our reported results. We believe the following accounting policies may involve a higher degree of judgment and complexity in their application and represent the critical accounting policies used in the preparation of our financial statements. For additional discussion of our significant

Policy	Judgments and Estimates	Effect if Actual Results Differ from Assumptions
Goodwill- Goodwill is reviewed annually for impairment as of March 31 or whenever events or changes in circumstances indicate the carrying value may not be recoverable. The fair value of goodwill is determined by considering both the income and market approach.	Determining the fair value of a reporting unit is judgmental in nature and involves the use of significant estimates and assumptions. • Estimates and assumptions including revenue growth rates and EBITDA used to calculate projected future cash flows, risk-adjusted discount rates, future economic and market conditions, and determination of appropriate market comparables. • The fair value estimates are based on assumptions management believes to be reasonable but are inherently uncertain.	We performed our annual impairment test for goodwill for all reporting units as of March 31, 2022 using a qualitative approach. We determined for our goodwill that it was not more likely than not that the fair value of the assets exceeded carrying value for fiscal years ended March 31, 2022. Future events and unanticipated changes to assumptions could require a provision for impairment in a future period.

Policy	Judgments and Estimates	Effect if Actual Results Differ from Assumptions
Definite-lived intangible assets-Definite-lived intangible assets are tested for recoverability whenever events or changes in circumstances indicate that carrying amounts of the asset group may not be recoverable. Asset groups are established primarily by determining the lowest level of cash flows available. If the estimated undiscounted future cash flows are less than the carrying amounts of such assets, an impairment loss is recognized to the extent the fair value of the asset less any costs of disposition is less than the carrying amount of the asset. Indefinite-lived intangible assets-Indefinite-lived intangible assets are tested for impairment annually as of March 31 or whenever events or changes in circumstances indicate the carrying value may be greater than fair value. Determining the fair value of these assets is judgmental in nature and involves the use of significant estimates and assumptions. We base our fair value estimates on assumptions we believe to be reasonable, but that are inherently uncertain. To estimate the fair value of these indefinite-lived intangible assets, we use an income approach, which utilizes a market derived rate of return to discount anticipated performance. An impairment loss is recognized when the estimated fair value of the intangible asset is less than the carrying value.	Determining the fair value of the definite-lived and indefinite-lived intangible assets is judgmental in nature and involves the use of significant estimates and assumptions.	We did not record any impairment charges for definite-lived intangible assets in fiscal 2022, 2021, or 2020. We performed our annual impairment test for indefinite-lived intangible assets as of March 31, 2022. We performed a qualitative impairment analysis and determined for our indefinite-lived intangible assets that it was not more likely than not that the fair value of the assets exceeded carrying value for fiscal years ended March 31, 2022. Future events and unanticipated changes to assumptions could require a provision for impairment in a future period.

Revenue Recognition- We generate revenue by selling pipe and related water management products primarily to distributors, retailers, buying groups and co-operative buying groups. Products are shipped predominately by our internal fleet, and we do not provide any additional revenue generating services after product delivery. Payment terms and conditions vary by contract. Revenue is recognized at the point in-time obligations under the terms of a contract with a customer are satisfied, which generally occurs upon the transfer of control of the promised goods. In substantially all of our contracts with customers, control is transferred to the customer upon delivery. We recognize revenue in an amount that reflects the consideration we expect to be entitled to in exchange for those goods or services.	We estimate and allocate variable consideration, such as right of return, credits or incentives, based on numerous factors, including the customer agreements and past transaction history.	If our historical experience differs from future experience, our estimates of variable consideration could differ.

Recent Accounting Pronouncements

For a discussion of recent accounting pronouncements, see "Note 1. Background and Summary of Significant Accounting Policies" to our consolidated financial statements included in "Item 8. Financial Statements and Supplementary Data."

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

We are subject to various market risks, primarily related to changes in interest rates, credit risk, raw material supply prices, and, to a lesser extent, foreign currency exchange rates. Our financial position, results of operations or cash flows may be negatively impacted in the event of adverse movements in the respective market rates or prices in each of these risk categories. Our exposure in each category is limited to those risks that arise in the normal course of business, as we do not engage in speculative, non-operating transactions.

Interest Rate Risk - We are subject to interest rate risk associated with our bank debt. Changes in interest rates impact the fair value of our fixed-rate debt, but there is no impact to earnings and cash flow. Alternatively, changes in interest rates do not affect the fair value of our variable-rate debt, but they do affect future earnings and cash flow. The Revolving Credit Facility and the Term Note, notes bear variable interest rates. The Revolving Credit Facility and Term Note bear interest either at LIBOR or the Prime Rate, at our option, plus applicable pricing margins. A 1.0% increase in interest rates on our variable-rate debt would increase our annual forecasted interest expense by approximately $5.4 million based on our borrowings as of March 31, 2022. Assuming the Revolving Credit Facility is fully drawn, each 1.0% increase or decrease in the applicable interest rate would change our interest expense by approximately $7.8 million, for the year ended March 31, 2022.

Credit Risk - Financial instruments that potentially subject us to a concentration of credit risk consist principally of accounts receivable. We provide our products to customers based on an evaluation of the customers' financial condition, generally without requiring collateral. Exposure to losses on receivables is principally dependent on each customer's financial condition. We monitor the exposure for credit losses and maintain allowances for anticipated losses. Concentrations of credit risk with respect to our accounts receivable are limited due to the large number of customers comprising our customer base and their dispersion among many different geographies and end markets.

Advanced Drainage Systems, Inc.

Raw Material and Commodity Price Risk - Our primary raw materials used in the production of our products are HDPE and PP resins. As these resins are hydrocarbon-based materials, changes in the price of feedstocks, such as crude oil derivatives and natural gas liquids, as well as changes in the market supply and demand may cause the cost of these resins to fluctuate significantly. Raw materials account for the majority of our cost of goods sold. Given the significance of these costs and the inherent volatility in supplier pricing, our ability to reflect these changes in the cost of resins in our product selling prices in an efficient manner contributes to the management of our overall risk and the potential impact on our results of operations. A 1% increase in the price of resin would increase our cost of goods sold by approximately $5.9 million.

We also maintain supply agreements with our major resin suppliers that provide multi-year terms and volumes that are in excess of our projected consumption. These supply agreements generally do not contain minimum purchase volumes or fixed prices. Accordingly, our suppliers may change their selling prices or other relevant terms on a monthly basis, exposing us to pricing risk.

Inflation Risk - Our cost of goods sold is subject to inflationary pressures and price fluctuations of the raw materials we use, primarily HDPE and PP resins. Historically, we have generally been able, over time, to recover the effects of inflation and price fluctuations through sales price increases and production efficiencies related to technological enhancements and improvements. However, we cannot reasonably estimate our ability to successfully recover any price increases.

Foreign Currency Exchange Rate Risk - We have operations in countries outside of the United States, which primarily use the respective local foreign currency as their functional currency. Each of these operations may enter into contractual arrangements with customers or vendors that are denominated in currencies other than its respective functional currency. Consequently, our results of operations may be affected by exposure to changes in foreign currency exchange rates and economic conditions in the regions in which we sell or distribute our products. Exposure to variability in foreign currency exchange rates from these transactions is managed, to the extent possible, by natural hedges which result from purchases and sales occurring in the same foreign currency within a similar period of time, thereby offsetting each other to varying degrees.

In addition to the foreign currency transaction-related gains and losses that are reflected within the results of operations, we are subject to foreign currency translation risk, as the financial statements for our foreign subsidiaries are measured and recorded in the respective subsidiary's functional currency and translated into U.S. dollars for consolidated financial reporting purposes. The resulting translation adjustments are recorded net of tax impact in the Consolidated Statements of Comprehensive Income (Loss).

Evaluation of Disclosure Controls and Procedures

Under the supervision and with the participation of our management, including our Chief Executive Officer and our Chief Financial Officer, we evaluated the effectiveness of our disclosure controls and procedures as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), as of March 31, 2022. Disclosure controls and procedures are designed to ensure that information required to be disclosed in our reports filed or submitted under the Exchange Act are recorded, processed, summarized and reported, within the time periods specified under Securities Exchange Commission ("SEC") rules and forms. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives, and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

Management's Report on Internal Control over Financial Reporting

Management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rules 13a-15(f) and 15d-15(f).

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

Management, including our Chief Executive Officer and our Chief Financial Officer, assessed the effectiveness of our internal control over financial reporting as of March 31, 2022. In making this assessment, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission ("COSO") in Internal Control - Integrated Framework (2013). A material weakness in internal controls 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 our annual or interim financial statements will not be prevented or detected on a timely basis. Because of its inherent limitations, even appropriate internal control over financial reporting may not prevent or detect misstatements.

Based on this assessment, management has concluded that the Company's internal control over financial reporting was effective as of March 31, 2022.

Deloitte & Touche LLP, our independent registered public accounting firm, has issued an audit report on the effectiveness of our internal control over financial reporting as of March 31, 2022 and this report is included herein.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting identified in management's evaluation pursuant to Rules 13a15(d) or 15d-15(d) of the Exchange Act during the quarter ended March 31, 2022 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the shareholders and the Board of Directors of Advanced Drainage Systems, Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Advanced Drainage Systems, Inc. and subsidiaries (the "Company") as of March 31, 2022 and 2021, the related consolidated statements of operations, comprehensive income (loss), stockholders' equity and mezzanine equity, and cash flows, for each of the three years in the period ended March 31, 2022, and the related notes and the financial statement schedule listed in the Index at Item 15 (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of March 31, 2022 and 2021, and the results of its operations and its cash flows for each of the three years in the period ended March 31, 2022, in conformity with accounting principles generally accepted in the United States of America.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of March 31, 2022, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated May 19, 2022, expressed an unqualified opinion on the Company's internal control over financial reporting.

Basis for Opinion

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

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

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current-period audit of the financial statements that was communicated or required to be communicated to the audit committee and that (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Employee Benefit Plans - Employee Stock Ownership Plan ("ESOP") - Refer to Note 13 to the financial statements

Critical Audit Matter Description

During the year ended March 31, 2022, the Company made a cash contribution to the ESOP of approximately $0.3 million to satisfy the outstanding balance on the ESOP loan. The repayment of the ESOP loan resulted in the release of shares of preferred stock from the pledge securing the ESOP Loan and the corresponding allocation of shares of preferred stock to ESOP participants' accounts. This resulted in the Company recording incremental compensation expense ("ESOP acceleration") of $30.4 million for year ended March 31, 2022.

F-1

Table of Contents

Advanced Drainage Systems, Inc.

We identified the ESOP acceleration as a critical audit matter because of the judgment applied by management in evaluating the accounting considerations associated with the matter. The accounting considerations included recognition of the ESOP acceleration and determining the appropriate presentation of the ESOP acceleration in the Company's Consolidated Statements of Operations. Our performance of audit procedures to evaluate these conclusions required a high degree of auditor judgment and an increased extent of audit effort, including the need to involve professionals in our firm with expertise and experience in accounting for similar transactions.

How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to the accounting considerations for the ESOP acceleration included the following, among others:

•We tested the operating effectiveness of management's internal controls over the ESOP acceleration, including management's controls over the evaluation of applicable accounting guidance.

•We assessed the reasonableness of management's conclusions for the ESOP acceleration by comparing such conclusions to the relevant accounting guidance.

•We tested the accuracy and completeness of the ESOP acceleration by evaluating the appropriateness of the key inputs used in determining the expense.

•We involved professionals in our firm with expertise and experience in accounting for similar transactions to assist in our evaluation of the appropriateness of management's conclusions for the ESOP acceleration.

•We evaluated the appropriateness of the Company's presentation and disclosures related to the ESOP acceleration.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Stockholders and the Board of Directors of Advanced Drainage Systems, Inc.

Opinion on Internal Control over Financial Reporting

We have audited the internal control over financial reporting of Advanced Drainage Systems, Inc. and subsidiaries (the "Company") as of March 31, 2022, based on criteria established in Internal Control - Integrated Framework (2013)issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of March 31, 2022, based on criteria established in Internal Control - Integrated Framework (2013) issued by COSO.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated financial statements as of and for the year ended March 31, 2022, of the Company and our report dated May 19, 2022, expressed an unqualified opinion on those financial statements.

Basis for Opinion

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

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

Definition and Limitations of Internal Control over Financial Reporting

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

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

ADVANCED DRAINAGE SYSTEMS, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. BACKGROUND AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Description of Business - Advanced Drainage Systems, Inc. and subsidiaries (collectively referred to as "ADS" or the "Company"), incorporated in Delaware, designs, manufactures and markets innovative water management solutions in the stormwater and onsite septic waste water industries, providing superior drainage solutions for use in the construction and agriculture marketplace. ADS's products are used across a broad range of end markets and applications, including non-residential, infrastructure and agriculture applications.

The Company's fiscal year begins on April 1 and ends on March 31. Unless otherwise noted, references to "year" pertain to the fiscal year. For example, 2022 refers to fiscal 2022, which is the period from April 1, 2021 to March 31, 2022.

The Company is managed and reports results of operations in three reportable segments: Pipe, Infiltrator and International. The Company also reports the results of its Allied Products and all other business segments as Allied Products & Other.

Principles of Consolidation - The consolidated financial statements include the Company, its wholly-owned subsidiaries, its majority owned subsidiaries, and variable interest entities ("VIEs") of which the Company is the primary beneficiary. The Company uses the equity method of accounting for equity investments where it exercises significant influence but does not hold a controlling financial interest. Such investments are recorded in Other assets in the Consolidated Balance Sheets and the related equity in earnings from these investments are included in Equity in net income of unconsolidated affiliates in the Consolidated Statements of Operations. All intercompany balances and transactions have been eliminated in consolidation.

Presentation - Certain prior year captions have been renamed to conform to the fiscal 2022 presentation. Cost of goods sold - ESOP acceleration and special dividend compensation and Selling, general and administrative - ESOP acceleration and special dividend compensation include the compensation expense triggered by the acceleration of the ESOP in fiscal 2022 discussed in "Note 13. Employee Benefit Plans" and the special dividend in fiscal 2020 discussed in "Note 16. Net Income Per Share and Stockholders' Equity."

Estimates - The preparation of consolidated 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, the disclosure of contingencies and liabilities at the balance sheet date and the reported amounts of revenues and expenses during the reporting period. Significant estimates include, but are not limited to, the allowance for credit losses, valuation of inventory, useful lives of property, plant and equipment and amortizing intangible assets, determination of the proper accounting for leases, valuation of equity method investments, goodwill, intangible assets and other long-lived assets for impairment, accounting for stock-based compensation and the ESOP, valuation of the redeemable convertible preferred stock, determination of allowances for sales returns, rebates and discounts, determination of the valuation allowance, if any, on deferred tax assets, and reserves for uncertain tax positions. Management's estimates and assumptions are evaluated on an ongoing basis and are based on historical experience, current conditions and available information. Management believes the accounting estimates are appropriate and reasonably determined; however, due to the inherent uncertainties in making these estimates, actual results could differ from those estimates.

Receivables and Allowance for Credit Losses - Receivables include trade receivables, net of an allowance for credit losses, and other miscellaneous receivables. Receivables at March 31, 2022 and 2021 are as follows:

(Amounts in thousands)	2022		2021
Trade receivables, net	$	339,585	$	233,753
Other miscellaneous receivables	2,168	2,438
Receivables, net	$	341,753	$	236,191

The Company extends credit to customers based on an evaluation of their financial condition and collateral is generally not required. The Company records an allowance for credit losses at the time accounts receivable are

recorded based on the Company's historical write-off activity, an evaluation of the current economic environment and the Company's expectations of future economic conditions.

Inventories - Inventories are stated at the lower of cost or net realizable value. The Company's inventories are maintained on the first-in, first-out ("FIFO") method. Costs include the cost of acquiring materials, including in-bound freight from vendors and freight incurred for the transportation of raw materials, tooling or finished goods between the Company's manufacturing plants and its distribution centers, direct and indirect labor, factory overhead and certain corporate overhead costs related to the production of inventory.

Property, Plant and Equipment and Depreciation Method - Property, plant and equipment are recorded at cost less accumulated depreciation, with the exception of assets acquired through acquisitions, which are initially recorded at fair value. Equipment acquired under finance lease is recorded at the present value of the future minimum lease payments. Depreciation is computed for financial reporting purposes using the straight-line method over the estimated useful lives of the related assets or the lease term, if shorter, as follows:

		Years
Buildings and leasehold improvements		20 to 45 or the lease term if shorter
Machinery and production equipment		3 to 18
Transportation equipment		3 to 12

Costs of additions and major improvements are capitalized, whereas maintenance and repairs that do not improve or extend the life of the asset are charged to expense as incurred. When assets are retired or disposed, the cost and related accumulated depreciation are removed from the asset accounts and any resulting gain or loss is reflected in Loss on disposal of assets and costs from exit and disposal activities in the Consolidated Statements of Operations. Construction in progress is also recorded at cost and includes capitalized interest, capitalized payroll costs and related costs such as taxes and other fringe benefits.

Goodwill - The Company records acquisitions resulting in the consolidation of an enterprise using the acquisition method of accounting. Under this method, the Company records the assets acquired, including intangible assets that can be identified, and liabilities assumed based on their estimated fair values at the date of acquisition. The purchase price in excess of the fair value of the identifiable assets acquired and liabilities assumed is recorded as goodwill.

Goodwill is reviewed annually for impairment as of March 31 or whenever events or changes in circumstances indicate the carrying value may be greater than fair value. If the fair value of the reporting unit exceeds the carrying value of the net assets assigned to that unit, goodwill is not considered impaired and the Company is not required to perform further testing. If the carrying value of a reporting unit's goodwill exceeds its fair value, then the Company would record an impairment loss equal to the difference. With respect to this testing, a reporting unit is a component of the Company for which discrete financial information is available and regularly reviewed by management. The fair value of each reporting unit is determined by considering both the income and market approach. Determining the fair value of a reporting unit is judgmental in nature and involves the use of significant estimates and assumptions. These estimates and assumptions include revenue growth rates and operating margins used to calculate projected future cash flows, risk-adjusted discount rates, future economic and market conditions, and determination of appropriate market comparison. The fair value estimates are based on assumptions management believes to be reasonable but are inherently uncertain. For the fiscal year ended March 31, 2021, the Company completed a quantitative assessment of the Infiltrator and Canada reporting units and determined no impairment charges were required. For the fiscal year ended March 31, 2020, the Company completed a quantitative fair value assessment for all reporting units and determined no impairment charges were required.

GAAP allows entities testing goodwill for impairment the option of performing a qualitative assessment before calculating the fair value of a reporting unit for the goodwill impairment test. If the qualitative assessment is performed, an entity is no longer required to calculate the fair value of a reporting unit unless the entity determines that, based on that assessment, it is more likely than not that the fair value is less than its carrying amount. The Company applied the qualitative assessment to all reporting units as of March 31, 2022. For all reporting units, except Infiltrator and Canada, the Company completed a qualitative assessment as of March 31, 2021. The qualitative assessments indicated that no impairment charges were required for goodwill.

Intangible Assets

Intangible Assets - Definite-Lived - Definite-lived intangible assets are amortized using the straight-line method or an accelerated method over their estimated useful lives and are tested for recoverability whenever events or changes in circumstances indicate that carrying amounts of the asset group may not be recoverable. Asset groups are established primarily by determining the lowest level of cash flows available. If the estimated undiscounted future cash flows are less than the carrying amounts of such assets, an impairment loss is recognized to the extent the fair value of the asset less any costs of disposition is less than the carrying amount of the asset. Determining the fair value of these assets is judgmental in nature and involves the use of significant estimates and assumptions.

Intangible Assets - Indefinite-Lived - Indefinite-lived intangible assets are tested for impairment annually as of March 31 or whenever events or changes in circumstances indicate the carrying value may be greater than fair value. Determining the fair value of these assets is judgmental in nature and involves the use of significant estimates and assumptions. The Company bases its fair value estimates on assumptions it believes to be reasonable, but that are inherently uncertain. To estimate the fair value of these indefinite-lived intangible assets, the Company uses an income approach, which utilizes a market derived rate of return to discount anticipated performance. An impairment loss is recognized when the estimated fair value of the intangible asset is less than the carrying value.

ADS completed a quantitative fair value measurement of indefinite-lived trademarks as of March 31, 2020. The test indicated that the fair value of the indefinite-lived trademarks substantially exceeded the carrying value, indicating that no impairment existed.

GAAP allows entities testing indefinite-lived intangible assets for impairment the option of performing a qualitative assessment before calculating the fair value of the indefinite-lived intangible assets for the impairment test. If the qualitative assessment is performed, an entity is no longer required to calculate the fair value of an indefinite-lived intangible assets unless the entity determines that, based on that assessment, it is more likely than not that its fair value is less than its carrying amount. ADS applied the qualitative assessment to specific trademarks for the annual impairment tests performed as of March 31, 2022 and 2021. For the qualitative tests, ADS assessed various assumptions, events and circumstances that would have affected the estimated fair value of the reporting unit as compared to its latest quantitative fair value measurement. The results of these assessments indicated that it is not more likely than not that the trademarks fair value is less than the reporting unit carrying value. The Company did not incur any impairment charges for Intangible assets.

Other Assets -Other assets include operating lease right of use assets, investments in unconsolidated affiliates accounted for under the equity method, capitalized software development costs, including cloud computing costs, deposits, central parts, and other miscellaneous assets. See "Note 5. Leases" for further information on the operating lease right of use assets. The Company capitalizes development costs for internal use software and defers implementation costs for hosting arrangements. Capitalization of software development costs and deferral of implementation costs for hosting arrangements begin in the application development stage and end when the asset is placed into service. The Company amortizes such costs using the straight-line method over estimated useful lives of 2 to 10 years, which is included in Selling, general and administrative expenses or Cost of goods sold within the Consolidated Statements of Operations depending on the nature of the asset and its intended use. Central parts represent spare production equipment items which are used to replace worn or broken production equipment parts and help reduce the risk of prolonged equipment outages. The cost of central parts is amortized on a straight-line basis over estimated useful lives of 3 to 10 years.

The Company evaluates its investments in unconsolidated affiliates for impairment whenever events or changes in circumstances indicate that the carrying amount might not be recoverable and recognizes an impairment loss when a decline in value below carrying value is determined to be other-than-temporary. Under these circumstances, the Company would adjust the investment down to its estimated fair value, which then becomes its new carrying value.

Leases - The Company determines whether an arrangement contains a lease at inception by determining if the contract conveys the right to control the use of identified plant, property, and equipment for a period of time in exchange for consideration and other facts and circumstances as defined by Accounting Standards Codification 842, Leases("ASC 842"). For each lease which has an accounting lease term of greater than 12 months, the Company records the right-of-use asset and lease liability on the balance sheet. The accounting lease term includes cancellable and renewal periods which are reasonably assured. The lease liability is measured utilizing the incremental borrowing rate unless the Company can specifically determine the rate implicit in the lease. Leases are evaluated for appropriate classification as operating or financing at lease inception. For leases classified as finance leases at lease inception, the

Company records a finance lease asset and lease financing obligation equal to the present value of the minimum lease payments. The finance lease right of use asset is recorded in Property, plant and equipment, net and amortized to its expected residual value at the end of the lease term using the straight-line method, and the lease financing obligation is amortized using the effective interest method over the lease term with the rental payments being allocated to principal and interest. For leases classified as operating leases, the Company records the operating lease right of use asset in Other assets and operating lease obligation in Other accrued liabilities and Other liabilities. Operating lease rent expense is recognized over the useful life using the straight-line method.

Foreign Currency Translation - Assets and liabilities of foreign subsidiaries with a functional currency other than the U.S. dollar are translated into U.S. dollars at the current rate of exchange on the last day of the reporting period. Revenues and expenses are translated at a monthly average exchange rate and equity transactions are translated using either the actual exchange rate on the day of the transaction or a monthly average historical exchange rate. For the fiscal years ended March 31, 2022 and 2021, the Company's Accumulated other comprehensive loss ("AOCL") consisted of foreign currency translation gains and losses.

Net Sales - The Company generates revenue by selling pipe and related water management products primarily to distributors, retailers, buying groups and co-operative buying groups. Products are shipped predominately by the Company's internal fleet, and the Company does not provide any additional revenue generating services after product delivery. Payment terms and conditions vary by contract.

Revenue is recognized at the point in-time obligations under the terms of a contract with a customer are satisfied, which generally occurs upon the transfer of control of the promised goods. In substantially all of the Company's contracts with customers, control is transferred to the customer upon delivery. The Company recognizes revenue in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services.

Shipping Costs - The Company incurs shipping costs to deliver products to customers using an in-house fleet or common carrier. Typically shipping costs are prepaid and included in the product price; however, in some instances, the Company bills shipping costs to customers. Shipping costs are also incurred to physically move raw materials, tooling and products between manufacturing and distribution facilities. Shipping costs to deliver products to customers for the fiscal years ended March 31, 2022, 2021, and 2020 were $242.0 million, $174.2 million, and $149.0 million, respectively, and are included in Cost of goods sold.

Stock-Based Compensation - See "Note 14. Stock-Based Compensation" for information about the stock-based compensation award programs and related accounting policies.

Advertising - The Company expenses advertising costs as incurred. Advertising costs are recorded in Selling, general and administrative expenses in the Consolidated Statements of Operations. The total advertising costs were $6.0 million, $4.1 million, and $4.9 million for the fiscal years ended March 31, 2022, 2021, and 2020, respectively.

Self-Insurance - The Company is self-insured for short-term disability and medical coverage it provides for substantially all eligible employees. The Company is self-insured for medical claims up to the individual and aggregate stop-loss coverage limits. The Company accrues for claims incurred but not reported based on an estimate of future claims related to events that occurred prior to the fiscal year end if it has not met the aggregate stop-loss coverage limit. Amounts expensed totaled $45.6 million, $42.4 million, and $50.3 million for the fiscal years ended March 31, 2022, 2021, and 2020, respectively, of which employees contributed $10.7 million, $8.5 million, and $7.9 million, respectively.

ADS is also self-insured for various other general insurance programs to the extent of the applicable deductible limits on the Company's insurance coverage. These programs include primarily automobile, general liability, cybersecurity and employment practices coverage with a deductible of $0.5 million per occurrence for general liability and $0.8 million per occurrence for automobile or claim incurred. Amounts expensed during the period, including an estimate for claims incurred but not reported at year end, were $3.2 million, $1.7 million, and $2.5 million, for the years ended March 31, 2022, 2021, and 2020, respectively.

ADS is also self-insured for workers' compensation insurance with stop-loss coverage for claims that exceed $0.3 million per incident up to the respective state statutory limits. Amounts expensed, including an estimate for claims incurred but not reported, were $4.1 million, $3.0 million, and $3.0 million for the fiscal years ended March 31, 2022, 2021, and 2020, respectively.

Income Taxes - Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized and represent the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. They are measured using the enacted tax rates expected to apply to taxable income in the years in which the related temporary differences are expected to be recovered or settled. Valuation allowances are established against deferred tax assets when it is more likely than not that the realization of those deferred tax assets will not occur. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. The deferred income tax provision represents the change during the reporting period in the deferred tax assets and deferred tax liabilities. Penalties and interest recorded on income taxes payable are recorded as part of Income tax expense.

The Company determines whether an uncertain tax position is more likely than not to be sustained upon examination, including resolution of any related appeals or litigation process, based upon the technical merits of the position. For tax positions meeting the more likely than not threshold, the tax amount recognized in the financial statements is the largest amount of tax benefit that has a greater than 50% likelihood of being realized upon ultimate settlement with the relevant taxing authority.

Fair Values - The fair value framework requires the categorization of assets and liabilities into three levels based upon assumptions (inputs) used to price the assets or liabilities. Level 1 provides the most reliable measure of fair value, whereas Level 3 generally requires significant management judgment. ADS's policy for determining when transfers between levels have occurred is to use the actual date of the event or change in circumstances that caused the transfer.

Concentrations of Risk- The Company has a large, active customer base of approximately 17,000 customers with two customers, Ferguson Enterprises and Core and Main, each representing more than 10% of annual net sales. Such customers accounted for 24.2%, 22.8%, and 24.3% of fiscal 2022, 2021 and 2020 net sales, respectively. The Company's customer base is diversified across the range of end markets that it serves.

Financial instruments that potentially subject the Company to a concentration of credit risk consist principally of Receivables. The Company provides its products to customers based on an evaluation of the customers' financial condition, generally without requiring collateral. Exposure to losses on Receivables is principally dependent on each customer's financial condition. The Company performs ongoing credit evaluations of its customers. The Company monitors the exposure for credit losses and maintains allowances for anticipated losses. Concentrations of credit risk with respect to Receivables are limited due to the large number of customers comprising the Company's customer base and their dispersion across many different geographies. One customer, Ferguson Enterprises, accounted for approximately 16.4% and 18.1% of Receivables at March 31, 2022 and 2021, respectively.

Derivatives - The Company recognizes derivative instruments as either assets or liabilities and measure those instruments at fair value. ADS uses interest rate swaps, commodity options in the form of collars and swaps, and foreign currency forward contracts to manage various exposures to interest rate, commodity price, and exchange rate fluctuations. These instruments do not qualify for hedge accounting treatment. Interest rate swap gains and losses resulting from the difference between the spot rate and applicable base rate is recorded in the Consolidated Statements of Operations in Interest expense. For commodity options in the form of collars and swaps, and foreign currency forward contracts, gains and losses from contract settlements and changes in fair value of the derivative instruments are recognized in Derivative (gains) losses and other (income) expense, net in the Consolidated Statements of Operations. The Company's policy is to present all derivative balances on a gross basis.

Recent Accounting Pronouncements

Recently Adopted Accounting Guidance

Simplifying the Accounting for Income Taxes - In December 2019, the Finance Accounting Standards Board ("FASB") issued an ASU to simplify the accounting for income taxes by removing certain exceptions to the general principles in ASC 740, Income Taxesand improve the comparability of financial statements. The amendments in this ASU are effective for fiscal years beginning after December 15, 2020, and early adoption is permitted. The Company adopted this standard effective April 1, 2021. The Company's adoption of the standard had no impact on the Company's Consolidated Financial Statements.

Recent Accounting Guidance Not Yet Adopted

Reference Rate Reform - In March 2020, the FASB issued an ASU that provides optional expedients and exceptions related to financial reporting impacts related to the expected market transition from LIBOR to another reference rates. The amendments are effective on March 12, 2020 and an entity may elect to adopt prospectively through December 31, 2022. The Company is currently evaluating the impact of this standard on the Consolidated Financial Statements.

Except for the pronouncements described above, there have been no new accounting pronouncements issued or adopted since the filing of the fiscal 2021 Form 10-K that have significance, or potential significance, to the Consolidated Financial Statements.

2. REVENUE RECOGNITION

Revenue is recognized at the point in-time obligations under the terms of a contract with a customer are satisfied, which generally occurs upon the transfer of control of the promised goods. In substantially all of the Company's contracts with customers, control is transferred to the customer upon delivery. The Company recognizes revenue in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services. Revenue is presented in the Consolidated Statements of Operations net of allowances for returns, rebates, discounts, and taxes collected concurrently with revenue-producing activities.

The Company disaggregates net sales by Domestic, International and Infiltrator and further disaggregates Domestic and International by product type, consistent with its reportable segment disclosure. This disaggregation level best depicts how the nature, amount, timing and uncertainty of revenue and cash flows are affected by economic factors. Refer to "Note 18. Business Segments Information" for the Company's disaggregation of Net sales by reportable segment.

Significant Judgments- The Company's performance obligation under contracts with customers is to sell and deliver pipe and related water management products. The Company's contracts with customers may contain multiple performance obligations by promising to deliver multiple products to the customer. For these contracts, the Company accounts for individual performance obligations separately if they are distinct. The transaction price is allocated to the separate performance obligations on a relative standalone selling price basis.

The Company's products are generally sold with a right of return, and the Company may provide credits or incentives, which are accounted for as variable consideration when estimating the amount of revenue to recognize. Variable consideration is estimated at contract inception and updated at the end of each reporting period as additional information becomes available and only to the extent that it is probable that a significant reversal of any incremental revenue will not occur.

Contract Balances- The Company recognizes a contract asset representing the Company's right to recover products upon the receipt of returned products and a contract liability for the customer refund. The following table presents the balance of the Company's contract asset and liability as of March 31, 2022 and 2021:

	March 31, 2022		March 31, 2021
	(In thousands)
Contract asset - product returns	$	978	$	694
Refund liability	2,356	1,801

Practical Expedients and Exemptions- The Company expenses incremental costs to obtain a contract (e.g. sales commissions) when incurred as the amortization period would have been one year or less. These costs are recorded within Selling, general and administrative expenses on the Consolidated Statements of Operations.

The Company elected to account for shipping and handling costs as activities to fulfill the promise to transfer the goods when these activities are performed after a customer obtains control of the goods.

The Company elected to exclude from the transaction price all sales taxes that are assessed by a governmental authority and that are imposed on and concurrent with a specific revenue-producing transaction and collected by the Company from a customer, for example, sales, use, value added, and some excise taxes.

Further, the Company does not disclose the value of unsatisfied performance obligations for contracts with an original expected length of one year or less.

3. ACQUISITIONS

Fiscal 2022 Acquisition of Jet - On December 3, 2021, the Company completed its acquisition of Jet Polymer Recycling, Inc., The Traylor Group, Inc. and certain assets of EAT Properties, L.L.C. (collectively "Jet"). Jet was a privately-owned recycling company located in the southeastern United States. The acquisition of Jet expands the Company's plastic recycling capabilities to support future growth. Jet is currently the largest supplier of recycled polypropylene plastic for Infiltrator. Jet is included in the Pipe reporting segment. The total fair value of consideration transferred was $49.5 million.

The following table summarizes the consideration transferred and the preliminary purchase price allocation of assets acquired and liabilities assumed. The purchase price allocation for assets acquired and liabilities assumed is preliminary and will be finalized when valuations are complete and final assessments of the fair value of acquired assets and assumed liabilities are completed. Such finalization may result in material changes from the preliminary purchase price allocations. The Company's estimates and assumptions are subject to change during the measurement period (up to one year from the closing date), as the Company continues to finalize the valuations of assets acquired and liabilities assumed.

The preliminary goodwill of $11.1 million represents the excess of consideration transferred over the preliminary fair value of assets acquired and liabilities assumed and is attributable to expected operating efficiencies. The goodwill is not deductible for income tax purposes and is assigned to the Pipe segment.

The preliminary purchase price excludes transaction costs. The Company incurred $2.6 million of transaction costs related to the acquisition such as legal, accounting, valuation and other professional services during the fiscal year ended March 31, 2022. These costs are included in Selling, general and administrative expenses in the Consolidated Statements of Operations and Consolidated Statements of Comprehensive Income.

The identifiable intangible assets recorded in connection with the closing of the acquisition of Jet are based on preliminary valuations including supplier and customer relationships, tradename and non-compete agreements totaling $13.2 million.

Company has included renewal options which are reasonably certain to be exercised in its right-of-use assets and lease liabilities. The Company's lease payments are generally fixed.

For all leases with an initial expected term of more than 12 months, the Company recorded, at the adoption date of ASC 842 or lease commencement date for leases entered into after the adoption date, a lease liability, which is the lessee's obligation to make lease payments arising from a lease, measured on a discounted basis; and a right-of-use asset, which is an asset that represents the lessee's right to use, or control the use of, a specified asset for the lease term. The Company will utilize its collateralized incremental borrowing rate commensurate to the lease term as the discount rate for its leases, unless the Company can specifically determine the lessor's implicit rate. The incremental borrowing rate for each lease is determined based on the Company's credit rating, adjusted for the impacts of collateral, and the lease term.

8. FAIR VALUE MEASUREMENT AND DERIVATIVE TRANSACTIONS

The Company uses commodity options in the form of collars and swaps and has previously used interest rate swaps and foreign currency forward contracts to manage its various exposures to interest rate, commodity price fluctuations and foreign currency exchange rate fluctuations. Mark-to-market adjustments for changes in fair value and contract settlement gains and losses for collars, commodity swaps and foreign currency forward contracts are recorded in the Consolidated Statements of Operations in Derivative gains and other income, net.

When applying fair value principles in the valuation of assets and liabilities, the Company is required to maximize the use of quoted market prices and minimize the use of unobservable inputs. The Company has not changed its valuation techniques used in measuring the fair value of any financial assets or liabilities during the fiscal periods presented. The fair value estimates take into consideration the credit risk of both the Company and its counterparties.

When active market quotes are not available for financial assets and liabilities, the Company uses industry standard valuation models. Where applicable, these models project future cash flows and discount the future amounts to a present value using market-based observable inputs including credit risk, interest rate curves, foreign currency rates and forward and spot prices for currencies. In circumstances where market-based observable inputs are not available, management judgment is used to develop assumptions to estimate fair value.

Recurring Fair Value Measurements

The assets and liabilities carried at fair value as of the fiscal years ended March 31 were as follows:

Valuation of Debt - The carrying amounts of current financial assets and liabilities approximate fair value because of the immediate or short-term maturity of these items, or in the case of derivative instruments, because they are recorded at fair value. The following table presents the carrying and fair value of the Company's Senior Notes (as defined below and further discussed in "Note 11. Debt") for the periods presented:

	March 31, 2022		March 31, 2021
(Amounts in thousands)	Fair Value		Carrying Value		Fair Value		Carrying Value
Senior Notes	$	349,902	$	350,000	$	367,633	$	350,000
Equipment Financing	29,302	31,254	-	-
Total	$	379,204	$	381,254	$	367,633	$	350,000

The fair value of the Senior Notes was determined based on a quoted market data for the Company's Senior Notes. The categorization of the framework used to evaluate the Senior Notes is considered Level 2. The Company believes the carrying amount on the remaining long-term debt, including the Term Loan Facility and Revolving Credit Facility, is not materially different from its fair value as the interest rates and terms of the borrowings are similar to currently available borrowings.

Senior Notes due 2027 - On September 23, 2019, the Company issued $350.0 million aggregate principal amount of 5.0% senior notes due 2027 (the "Senior Notes") pursuant to an Indenture, dated September 23, 2019 (the "Indenture"), among the Company, the guarantors party thereto (the "Guarantors") and U.S. Bank National Association, as Trustee (the "Trustee"). The Senior Notes are guaranteed by each of the Company's present and future direct and indirect wholly owned domestic subsidiaries that is a guarantor under the Company's Senior Secured Credit Facility. The Senior Notes were offered and sold either to persons reasonably believed to be "qualified institutional buyers" pursuant to Rule 144A under the Securities Act of 1933 (the "Securities Act") or to persons outside the United States under Regulation S of the Securities Act.

Interest on the Senior Notes will be payable semi-annually in cash in arrears on March 31 and September 30 of each year, commencing on March 31, 2020, at a rate of 5.0% per annum. The Senior Notes will mature on September 30, 2027. The Company used the majority of the net proceeds from the offering of the Senior Notes for the repayment of $300.0 million of its outstanding borrowings. The deferred financing costs associated with the Senior Notes totaled $2.1 million and are recorded as a direct reduction from the carrying amount of the related debt.

The Company may redeem the Senior Notes, in whole or in part, at any time on or after September 30, 2022 at established redemption prices. At any time prior to September 30, 2022, the Company may also redeem up to 40% of the Senior Notes with net cash proceeds of certain equity offerings at a redemption price equal to 105.0% of the principal amount of the Senior Notes to be redeemed, plus accrued and unpaid interest, if any, to, but excluding, the redemption date. In addition, at any time prior to September 30, 2022, the Company may redeem the Senior Notes, in whole or in part, at a redemption price equal to 100% of the principal amount of the Senior Notes to be redeemed, plus accrued and unpaid interest, if any, to, but excluding, the redemption date plus an applicable "make-whole" premium.

The Indenture contains customary events of default, including, among other things, payment default, failure to comply with covenants or agreements contained in the Indenture or the Senior Notes and certain provisions related to bankruptcy events. The Indenture also contains customary negative covenants.

Revolving Credit Facility - On September 24, 2019, the Company successfully completed a $700 million syndication of the remaining balance of its credit facility subsequent to the common stock offering and Senior Notes due 2027 and in connection with the syndication, the Company amended the Base Credit Agreement (the "Senior Secured Credit Facility"). The Senior Secured Credit Facility reduced the applicable margin utilized in the determination of the interest rate, as well as other provisions.

The Senior Secured Credit Facility provides for a term loan facility in an initial aggregate principal amount of $700 million (the "Term Loan Facility"), a revolving credit facility in an initial aggregate principal amount of up to $350 million (the "Revolving Credit Facility"), a letter of credit sub-facility in the initial aggregate available amount of up to $50 million, as a sublimit of such Revolving Credit Facility (the "L/C Facility") and a swing line sub-facility in the aggregate available amount of up to $50 million, as a sublimit of the Revolving Credit Facility (together with the Term Loan Facility, the Revolving Credit Facility and the L/C Facility, the "Senior Secured Credit Facility"). Letters of credit outstanding at March 31, 2022 amount to $9.2 million and reduced the availability of the Revolving Credit Facility.

In connection with entering into the Senior Secured Credit Facility, the Company capitalized approximately $0.4 million in deferred financing fees. To the extent not previously paid, all then-outstanding amounts under the Term Loan Facility are due and payable on the maturity date of the Term Loan Facility, which is seven years from the Closing Date. Borrowings under the Revolving Credit Facility are available beginning on September 24, 2019 and, to the extent not previously paid, all then-outstanding amounts under the Revolving Credit Facility are due and payable on the maturity date of the Revolving Credit Facility, which is five years from the Closing Date.

At the option of the Company, borrowings under the Term Loan Facility and under the Revolving Credit Facility (subject to certain limitations) bear interest at either a base rate (as determined pursuant to the Senior Secured Credit Facility) or at a Eurocurrency Rate, based on LIBOR (as defined in the Senior Secured Credit Facility), plus the applicable margin as set forth therein from time to time. In the case of the Revolving Credit Facility, the applicable margin is based on the Company's consolidated senior secured net leverage ratio (as defined in the Senior Secured Credit Facility). All borrowings under the Term Loan Facility used to finance the acquisition of Infiltrator as described above initially bear interest at a Eurocurrency Rate applicable to Eurocurrency Loans (as defined in the Senior Secured Credit Facility) denominated in U.S. Dollars.

The Company is also required to pay a commitment fee that is based upon the undrawn amounts of the Revolving Credit Facility at a rate per annum based upon a calculated ratio as prescribed within the Senior Secured Credit Facility. As of March 31, 2022, the rate the Company was committed to paying on the undrawn portion was equal to 0.2%.

The Company's obligations under the Senior Secured Credit Facility have been secured by granting a first priority lien on substantially all of the Company's assets (subject to certain exceptions and limitations), and each of StormTech, LLC, Advanced Drainage of Ohio, Inc. and Infiltrator Water Technologies, LLC (collectively the "Guarantors") has agreed to guarantee the obligations of the Company under the Senior Secured Credit Facility and to secure the obligations thereunder by granting a first priority lien in substantially all of such Guarantor's assets (subject to certain exceptions and limitations).

Equipment Financing - In November 2021, the Company purchased material handling equipment, trucks and trailers previously leased under a master lease agreement and classified as finance leases. The purchase was funded with debt through the Master Lease Agreement and Interim Funding Schedule with Fifth Third. The assets acquired are titled to the Company and included in Property, plant and equipment, net on the Company's Consolidated Balance Sheet. The equipment financings have a term of between 12 and 84 months, based on the life of the equipment, and bear a weighted average interest of 1.4%. The current portion of the equipment financing is $12.5 million and the long-term portion is $18.8 million at March 31, 2022.

Principal Maturities- Maturities of long-term debt (excluding interest and deferred financing costs) as of March 31, 2022 are summarized below:

13. EMPLOYEE BENEFIT PLANS

Employee Stock Ownership Plan ("ESOP") - The Company established the Advanced Drainage Systems, Inc. ESOP (the "ESOP" or the "Plan") effective April 1, 1993. The Plan was funded through a transfer of assets from the Company's tax-qualified profit-sharing retirement plan, as well as a 30-year term loan from ADS. Prior to the loan repayment in March 2022, the Plan operated as a tax-qualified leveraged ESOP and was designed to enable eligible employees to acquire stock ownership interest in ADS. Employees of ADS who have reached the age of 18 were generally eligible to participate in the Plan on March 31 after six months of service. Upon retirement, disability, death, or vested terminations, (i) a participant or designated beneficiary was able to elect to receive the amount in their account attributable to the 1993 transfer of assets from the Company's tax-qualified profit sharing retirement plan in the form of cash or ADS stock with any fractional shares paid in cash; (ii) stock credited to the participants' ESOP stock account resulting from the ESOP's loan repayments were distributed in the form of ADS stock, and (iii) amounts credited to the participants' ESOP cash account were distributed in the form of cash. Upon attainment of age 50 and seven years of participation in the Plan, a participant could elect to diversify specified percentages of the number of shares of ADS stock credited to the participant's ESOP stock account in compliance with applicable law.

The Company was obligated to make contributions to the Plan, which, when aggregated with the Plan's dividends on the Plan's unallocated shares of redeemable convertible preferred stock, equal the amount necessary to enable the Plan to make its regularly scheduled payments of principal and interest due on its term loan to ADS. As the Plan made annual payments of principal and interest, an appropriate percentage of preferred stock was allocated to ESOP participants' accounts in accordance with plan terms that are compliant with applicable Internal Revenue Code and regulatory provisions. Required dividends on allocated shares are generally passed through and paid in cash to the participants based on the total shares in their account and required dividends on unallocated shares are paid in cash to the Plan and generally used to service the Plan's debt.

The carrying value of redeemable convertible preferred stock held by the ESOP trust, but not yet earned by the ESOP participants or used for dividends, was reported as Deferred compensation - unearned ESOP shares within the Mezzanine equity section of the Consolidated Balance Sheets. In February 2022, the Company made a cash contribution to the ESOP, and the ESOP repaid the remaining ESOP loan triggering the release of the remaining 0.3 million shares of Preferred Stock from the pledge, resulting in the ESOP acceleration. As a result of the ESOP acceleration, the Company recognized additional compensation expense of $30.4 million. In April 2022, all currently outstanding shares of Preferred Stock held by the ESOP were converted into shares of the Company's common stock at the Conversion Rate of 0.7692.

Compensation expense and related dividends paid with ESOP shares for services rendered throughout the period are recognized based upon the annual fair value of the shares allocated. Deferred compensation - unearned ESOP shares is relieved at fair value, with any difference between the annual fair value and the carrying value of shares when allocated being added to Additional paid in capital. Information regarding ESOP compensation expense (excluding the ESOP Acceleration and Special Dividend Compensation) are included below:

(Amounts in thousands, except per share values)	2022	2021	2020
Fair value of shares allocated	$	91.41	$	79.56	$	22.70
Average annual fair value per share	$	85.49	$	51.13	$	21.31
ESOP compensation expense	$	53,401	$	44,981	$	20,126

Redeemable Convertible Preferred Stock - Prior to the conversion of preferred stock to common stock, the Trustee of the Company's ESOP had the ability to put shares of the redeemable convertible preferred stock to the Company absent a market for the Company's common stock, and as a result the redeemable convertible preferred stock was classified as Mezzanine equity in the Company's Consolidated Balance Sheets. The put option requirements of the Internal Revenue Code apply in the event that the Company's common stock is not a registration type class of security or its trading has been restricted. Therefore, the holders of Redeemable convertible preferred stock had a put right to require the Company to repurchase such shares in the event that the common stock is not listed for trading or otherwise quoted on the NYSE, AMEX, NASDAQ, or any other market more senior than the OTC Bulletin Board. As of March 31, 2022, the applicable redemption value was $0.7818 per share as there were no unpaid cumulative dividends.

F-27

Table of Contents

Advanced Drainage Systems, Inc.

The Redeemable convertible preferred stock has a required cumulative 2.5% dividend (based on the liquidation value of $0.7818 per share) and is convertible at a rate of 0.7692 shares of common stock for each share of Redeemable convertible preferred stock. The 2.5% annual dividend is payable in cash or additional shares of the Redeemable convertible preferred stock.

On April 11, 2022, our ESOP was merged into our existing 401(k) retirement plan effective April 1, 2022 (the "KSOP") completed the conversion of all outstanding shares of our preferred stock held by the ESOP on March 31, 2022, and then by the KSOP into common stock, in accordance with the conversion terms of the preferred stock. After the conversion, the common stock held by the KSOP will remain classified as mezzanine equity as the shares are subject to the put option requirements of the Internal Revenue Code.

The Company has defined contribution postretirement benefit plans covering Canadian employees. The Company recognized costs of $1.5 million, $0.6 million and $0.5 million in the fiscal years ended March 31, 2022, 2021, and 2020, respectively.

Compensation expense for stock options is recognized on a straight-line basis over the employee's requisite service period, which is generally the vesting period of the grant. The Company estimates the fair value of stock options using a Black-Scholes option-pricing model. The following table summarizes the assumptions used in estimating the fair value of stock options:

	2022	2021	2020
Common stock price	$105.82		$41.97 - $71.55		$27.44 - $41.85
Expected stock price volatility	41.0%		35.5% - 36.3%		30.1% - 30.9%
Risk-free interest rate	1.1%		0.4% - 0.6%		1.4% - 2.3%
Weighted-average expected life (years)	6.0		6.0		6.0
Dividend yield	0.3%		0.5% - 0.9%		0.9% - 1.3%

The fair value of restricted stock and performance-based restricted stock units is based on the fair value of the Company's common stock at the date of grant. Compensation expense is recognized on a straight-line basis over the employee's requisite service period, which is generally the vesting period of the grant.

2017 Omnibus Plan

On May 24, 2017, the Board of Directors approved the 2017 Omnibus Incentive Plan which was approved by the Company's stockholders on July 17, 2017 (the "2017 Incentive Plan"). On May 19, 2021, the Board of Directors adopted an amendment to the 2017 Incentive Plan to increase the total number of shares available for issuance from 3.5 million to 5.0 million, which was approved by the Company's stockholders on July 22, 2021. The 2017 Incentive Plan, as amended, provides for the issuance of a maximum of 5.0 million shares of the Company's common stock for awards made thereunder, which awards may consist of stock options, restricted stock, restricted stock units, stock appreciation rights, phantom stock, cash-based awards, performance awards (which may take the form of performance cash, performance units or performance shares) or other stock-based awards. The Company had approximately 2.6 million shares available for awards as of March 31, 2022.

For the performance units granted in fiscal 2022, 2021 and 2020, 50% of the award is based upon the achievement of certain levels of Return on Invested Capital for the performance period and 50% is based upon the achievement of certain levels of Free cash flow or cash flows from operations for the performance period.The performance units each have a 3-year performance period. The performance units, and any accrued dividend equivalents, will be settled in shares of the Company's common stock, if the applicable performance and service conditions are satisfied.

In addition to the performance units based on ADS performance, the Company issued performance units based on the achievements of other performance targets. During fiscal year 2020, the Company granted 0.1 million units, subject to achieving predetermined synergies of the now consolidated legacy ADS business and Infiltrator, and 0.1 million units, subject to performance conditions of the Infiltrator reportable segment. For the performance units based on the Infiltrator reportable segment, 75% of the award is based upon the achievement of certain levels of Adjusted EBITDA for the performance period and 25% is based upon the achievement of certain levels of Free cash flow for the performance period. These two performance unit grants have a performance period from August 1, 2019 through March 31, 2022.

(a) This includes the special dividend paid in the first quarter of fiscal 2020 that resulted in $246.8 million in additional stock-based compensation. Of the total stock-based compensation expense and dividends paid, approximately $242.9 million related to non-deductible stock appreciation and deductible dividends. This decreased the effective tax rate by 28.4%. See "Note 16. Net Income Per Share and Stockholders' Equity" for additional information.

As of March 31, 2022, the Company intends to repatriate earnings from Canada and believes that there will be no additional tax costs associated with the repatriation of such earnings other than any potential non-U.S. withholding taxes. No deferred tax liability has been recognized as of March 31, 2022. The Company has approximately $22.2 million of undistributed earnings from other foreign entities that are intended to be reinvested indefinitely with the exception of cash dividends paid by the Company's ADS Mexicana joint venture. It is not practicable to estimate the amount of U.S. tax, which would primarily relate to withholding tax, that might be payable on the eventual remittance of such undistributed earnings.

The tax effect of temporary differences that give rise to significant portions of the deferred tax assets and deferred tax liabilities at March 31 were comprised of:

Table of Contents

Advanced Drainage Systems, Inc.

As of March 31, 2022, The Company had unrecognized tax benefit of $0.7 million, which if resolved favorably, would reduce income tax expense by $0.7 million. A reconciliation of the beginning and ending amounts of unrecognized tax benefits for the years ended March 31 is as follows:

(Amounts in thousands)	2022	2021	2020
Balance at beginning of year	$	1,686	$	3,343	$	5,681
Tax positions taken in current year	-	-	-

Foreign translation adjustment	(5)	162	(134)
Balance at end of year	$	746	$	1,686	$	3,343

The short-term portion of the unrecognized tax benefit of $0.1 million at March 31, 2022 is recorded in Other accrued liabilities on the Company's Consolidated Balance Sheet. The long-term portion of unrecognized tax benefits are recorded in Other liabilities in the Company's Consolidated Balance Sheets. These amounts include potential accrued interest and penalties of $0.2 million and $0.5 million at March 31, 2022 and 2021, respectively.

The Company believes that over the next twelve months, it is reasonably possible that up to $0.1 million of unrecognized tax benefits could be resolved as the result of settlements of audits and the expiration of statutes of limitation. Final settlement of these issues may result in payments that are more or less than this amount, but the Company does not anticipate that the resolution of these matters will result in a material change to its consolidated financial position or results of operations.

The Company is currently open to audit under the statute of limitations by the IRS for the fiscal years ended March 31, 2019 through March 31, 2022. The majority of the Company's state income tax returns are open to audit under the statute of limitations for the years ended March 31, 2018 through March 31, 2022. The foreign income tax returns are open to audit under the statute of limitations for the years ended March 31, 2018 through March 31, 2022.

16. NET INCOME PER SHARE AND STOCKHOLDERS' EQUITY

Basic net income per share is calculated by dividing the Net income available to common stockholders by the weighted-average number of common shares outstanding during the period, without consideration for common stock equivalents. Diluted net income per share is computed by dividing the Net income available to common stockholders by the weighted-average number of common stock equivalents outstanding for the period.

Holders of redeemable convertible preferred stock participate in dividends on an as-converted basis when declared on common stock. As a result, redeemable convertible preferred stock meets the definition of participating securities, which requires the Company to apply the two-class method to compute both basic and diluted net income per share. The two-class method is an earnings allocation formula that treats participating securities as having rights to earnings that would otherwise have been available to common stockholders.

The dilutive effect of stock options, redeemable common stock, performance units and unvested nonparticipating restricted stock is based on the more dilutive of the treasury stock method or the diluted two-class method. These potential common stock equivalents are only included in the calculations when their effect is dilutive.

Common Stock Offering- On September 10, 2019, the Company issued and sold an aggregate of 10,350,000 shares of common stock, $0.01 par value per share, which included the full exercise of the underwriters' option to purchase additional shares, at a price of $29.75 per share, before underwriting discounts and commissions. The common stock was sold pursuant to the Company's shelf registration statement and related prospectus supplement. The Company received proceeds of $293.6 million from the issuance after deducting underwriting discounts and commissions and offering expenses. The Company used the net proceeds for the repayment of a portion of the outstanding borrowings under the Senior Secured Credit Facility.

Stockholders' Equity- The Company repurchased 2.6 million shares of common stock at a cost of $292.0 million during the fiscal year March 31, 2022. The Company did not repurchase any shares during the fiscal year ended March 31, 2021. The repurchases were made under the Board of Directors' authorization in May 2021 to repurchase an additional $250 million of ADS Common Stock, in addition to the $42 million previously authorized, in accordance with applicable security laws. In February 2022, the Company announced that the Board approved a $1.0 billion stock repurchase program (the "Repurchase Program") of ADS common stock in accordance with applicable securities laws. The Repurchase Program replaces the previously established share repurchase program, which has no remaining available capacity. The repurchase program does not obligate the Company to acquire any particular amount of common stock and may be suspended or terminated at any time at the Company's discretion.

Employees Stock Ownership Plan ("ESOP") and the Special Dividend- During fiscal year ended March 31, 2020, the Board of Directors approved a special cash dividend of $1.00 per share and quarterly dividends of $0.09 per share. The special and quarterly dividend were paid to all stockholders on June 14, 2019 to stockholders of record at the close of business on June 3, 2019. The total dividend payment was $81.6 million. The dividends received by the unallocated redeemable convertible preferred stock held in the ESOP trust was used to pay $12.0 million of the ESOP loan back to the Company resulting in approximately 11.6 million shares of the Company's redeemable convertible preferred stock being allocated to ESOP participants. The Company recognized $246.8 million in stock-based compensation expense based on the fair value on the date the Board of Directors approved the special dividend. The Board of Director's approval committed the ESOP to use those proceeds to pay down the ESOP loan. The special dividend compensation expense was recognized in Cost of goods sold - ESOP acceleration and special dividend compensation and Selling, general and administrative - ESOP acceleration and special dividend compensation on the

18. BUSINESS SEGMENT INFORMATION

ADS operates its business in three distinct reportable segments: "Pipe", "International" and "Infiltrator." "Allied Products & Other" represents the Company's Allied Products and all other business segments. "Pipe" and "Allied Products & Other" were previously included as Domestic. The Chief Operating Decision Maker ("CODM") reviews financial information and makes operational decisions based on Net Sales and Segment Adjusted Gross Profit. The Company calculates Segment Adjusted Gross Profit as net sales less costs of goods sold, depreciation and amortization, stock-based compensation, non-cash charges and certain other expenses. A measure of assets is not applicable, as segment assets are not regularly reviewed by the CODM for evaluating performance or allocating resources.

Pipe- The Pipe segment manufactures and markets high performance thermoplastic corrugated pipe throughout the United States. The Company maintains and serves these markets through product distribution relationships with many of the largest national and independent waterworks distributors, buying groups and co-ops, major national retailers as well as an extensive network of hundreds of small to medium-sized distributors across the U.S.
