Item 1.Business

Overview

Acuity Brands, Inc. (referred to herein as “we,” “our,” “us,” the “Company,” or similar references) is a market-leading industrial technology company. We use technology to solve problems in spaces and light. Through our two business segments, Acuity Brands Lighting and Lighting Controls (“ABL”) and the Intelligent Spaces Group (“ISG”), we design, manufacture, and bring to market products and services that make the world more brilliant, productive, and connected. We achieve growth through the development of innovative new products and services, including lighting, lighting controls, building management systems, and location-aware applications.

During fiscal 2021, we completed a realignment of our operations and structure to better support our business strategy, which resulted in the generation of two reportable segments: ABL and ISG.

ABL's lighting and lighting controls solutions are sold primarily through a network of independent sales agencies that cover specific geographic areas and market channels, by internal sales representatives, through consumer retail channels, and directly to large corporate accounts. Products are delivered directly from our manufacturing facilities or through a network of distribution centers, regional warehouses, and commercial warehouses using both common carriers and a Company-managed truck fleet. To serve international customers, the sales forces utilize a variety of distribution methods to meet specific individual customer or country requirements.

ABL comprised approximately 95% of consolidated revenues during fiscal 2021, 2020, and 2019.

ISG Segment

ISG delivers products and services that make spaces smarter, safer, and greener. ISG offers building management systems and location-aware applications and sells predominantly to system integrators. Our building management system includes products for controlling heating, ventilation, and air conditioning (“HVAC”), lighting, shades, and building access that deliver end-to-end optimization of those building systems. AtriusTM, our intelligent building platform, enhances the occupant experience, improves building system management, and automates labor intensive tasks while delivering operational energy efficiency and cost reductions. Through a connected and converged building system architecture, our platform delivers different applications, allows clients to upgrade over time with natural refresh cycles, and deploys new capability through both software and hardware updates. Customers of ISG primarily include system integrators as well as retail stores, airports, and enterprise campuses throughout North America and select international locations. ISG products and solutions are marketed under numerous brand names, including but not limited to Distech Controls®, AtriusTM, and Rockpile Ventures.

ISG comprised approximately 5% of consolidated revenues during fiscal 2021, 2020, and 2019.

Manufacturing and Distribution

We operate 19 manufacturing facilities, including six facilities in the United States, seven facilities in Mexico, two facilities in Europe, and four in Canada. We utilize a blend of internal and outsourced manufacturing processes and capabilities to fulfill a variety of customer needs in the most cost-effective manner. Certain critical processes, such as reflector forming and anodizing, high-end glass production, surface mount circuit board production, and assembly are performed (not exclusively) at Company-operated facilities, offering the ability to differentiate products through superior capabilities. Other components, such as LEDs, certain LED drivers, lamps, sockets, and ballasts

are purchased primarily from third-party vendors. Our investment in our production facilities is focused primarily on improving capabilities, product quality, and manufacturing efficiency as well as environmental, health, and safety compliance. We also utilize contract manufacturing from U.S., Asian, and European sources for certain products. The following table shows the percentage of finished goods manufactured and purchased in fiscal 2021 by significant geographic region.

Manufactured Purchased Total

United States 16 % 8 % 24 %

Others 5 % — % 5 %

We operate seven manufacturing facilities in Mexico, some of which are authorized to operate as Maquiladoras by the Ministry of Economy of Mexico. Maquiladora status allows us to import raw materials into Mexico duty-free, provided that such items, after processing, are exported from Mexico within a stipulated time frame. Maquiladora status, which is renewed periodically, is subject to various restrictions and requirements, including compliance with the terms of the Maquiladora program and other local regulations, which have become stricter in recent years.

Lighting and building technology solutions are delivered directly from manufacturing facilities or through a network of strategically located distribution centers, regional warehouses, and commercial warehouses in North America using both common carriers and a Company-managed truck fleet. For international customers, distribution methods are adapted to meet individual customer or country requirements. During fiscal 2021, net sales initiated outside of the U.S. represented approximately 14% of total net sales. See the Supplemental Disaggregated Information footnote of the Notes to Consolidated Financial Statements for additional information regarding the geographic distribution of net sales, operating profit, and long-lived assets.

Research and Development

Research and development (“R&D”) is defined as the critical investigation aimed at discovery of new knowledge and the conversion of that knowledge into the design of a new product or significant improvement to an existing product. We invest in the development of new products and solutions as well as the enhancement of existing offerings with a focus on improving the performance-to-cost ratio and energy efficiency. We also develop software applications and capabilities to enhance data analytics offerings. R&D expenses consist of compensation, payroll taxes, employee benefits, materials, supplies, and other administrative costs, but do not include all new product development costs. For fiscal 2021, 2020, and 2019, R&D expenses totaled $88.3 million, $82.0 million, and $74.7 million, respectively.

Sales and Marketing

Sales

We sell lighting and building technology solutions to customers in the North American market utilizing numerous sales forces, including internal direct salespeople and independent sales agencies, based on the channel and geography served. We also operate separate European sales forces, including independent international sales agencies and system integrators, and an international sales group coordinating export sales outside of North America and Europe.

See the Segment Information, Revenue Recognition, and Supplemental Disaggregated Information footnotes of the Notes to Consolidated Financial Statements for more information concerning our sales by segment, type, and geography.

Marketing

We market our product portfolio and service capabilities to customers and/or end users in multiple channels through a broad spectrum of marketing and promotional methods, including direct customer contact, trade shows, on-site training, print and digital advertising in industry publications, product brochures, and other literature, as well as through digital marketing and social media. We operate training and education facilities in several locations

throughout North America and Europe designed to enhance the lighting knowledge of customers and industry professionals.

Industry Overview

Based on industry sources and government information, we estimate that in fiscal 2021 the size of the North American lighting and building technology solutions market we serve (referred to herein as “addressable market”) was over $20 billion. We estimate that the addressable market increased in the lower single digits as compared with fiscal 2020. The addressable market includes non-portable luminaires as defined by the National Electrical Manufacturers Association; poles for outdoor lighting; emergency lighting fixtures and lighting equipment; daylighting; lighting controls; HVAC controls; and building technology controls, software, and systems. This market estimate is based on a combination of external industry data and internal estimates and excludes portable and vehicular lighting fixtures and certain related lighting components, such as non-integrated lighting ballasts and lamps.

We operate in a highly competitive industry that is affected by a number of general business and economic factors, such as, but not limited to, gross domestic product growth, employment levels, credit availability, interest rates, building costs, freight, construction-related labor availability, building occupancy rates, imports and trade, energy costs, freight costs, and commodity costs, including tariffs. Our market is based on non-residential and residential construction, both new as well as renovation and retrofit activity, which may be impacted by these general economic factors. Precise segmentation of the market by new construction and renovation activity is not available, though internal estimates based on third-party data estimate the size of the markets to be about the same. Non-residential construction spending on commercial, institutional, industrial, and infrastructure projects has a material impact on the demand for our lighting and building technology solutions. Demand for our residential lighting products is highly dependent on economic drivers, such as consumer spending and discretionary income, along with housing construction and home improvement spending.

Our market is influenced by: the development of new lighting technologies, including solid-state lighting, electronic drivers, embedded lighting controls, and more effective optical designs and lamps; federal, state, and local requirements for updated energy codes; incentives by federal, state, and local municipal authorities, as well as utility companies, for using more energy-efficient lighting and building technology solutions; and design strategies and technologies addressing sustainability and facilitating intelligent buildings. We are a leading provider of integrated lighting and building technology solutions based on these technologies and utilize internally developed, licensed, or acquired intellectual property. Solid-state lighting and digital building technology systems can be converged allowing for an optimal local operating system to increase efficiency and reduce costs while also delivering productivity benefits. We expect that the industry’s addressable market is likely to expand due to the benefits and value creation provided by our intelligent building platform services and location-aware and asset tracking applications. New entrants continue to develop capabilities and solutions that are both complementary as well as competitive to those of traditional industry participants.

Competition

We experience competition based on numerous factors, including features and benefits, price, brand name recognition, product quality, product and system design, energy efficiency, customer relationships, and service capabilities. The market for lighting and building technology solutions and services is competitive and continues to evolve through acquisition and consolidation activities. Additionally, the market for artificial intelligence and software solutions is active with a wide range of competitors, from existing large companies to startup organizations. Certain global and more diversified manufacturers may provide a broader product offering utilizing electrical, lighting, and building technology products as well as pricing benefits from the bundling of various offerings. In addition, there are new competitors, including Asian importers, small startup companies, and global electronics, technology, and software companies, offering competing solutions, sometimes deploying different technologies.

Regulations

We are subject to various federal, state, and local laws and regulations that impose increasingly complex, stringent and costly compliance activities. These regulations include but are not limited to, the Clean Water Act; the Safe Harbor data privacy program between the U.S. and European Union; the United States-Mexico-Canada-Free Trade Agreement (“USMCA”); regulations from the Occupational Safety and Health Administration agency (“OSHA”); the European Union’s General Data Protection Regulation; California’s Consumer Privacy Act and Connected Device Privacy Act; the Civil Rights Act of 1964; the U.S. Foreign Corrupt Practices Act (the “FCPA”); and the U.K. Bribery Act.

Table of Contents

On an ongoing basis, we allocate resources, including investments in capital and operating costs, to comply with laws and regulations. We do not currently believe that the costs of complying with government regulations have a material impact on our financial condition, results of operations, or cash flows. However, we may be affected by future standards, laws or regulations, including those imposed in response to energy, climate change, product functionality, geopolitical, corporate social responsibility, employee health and safety, privacy, or similar concerns. These standards, laws, or regulations may impact our costs of operation, the sourcing of raw materials, and the manufacture and distribution of our products and may place restrictions and other requirements or impediments on the products and solutions we can sell in certain geographical locations or may impact the willingness of certain investors to own our shares. See Part I. Item 1a. Risk Factors for additional information.

Raw Materials

Our production requires raw materials, including certain grades of steel and aluminum, electrical and electronic components, plastics, and other petroleum-based materials and components. We purchase most raw materials and other components on the open market and rely on third parties to provide certain finished goods. While these items are generally available from multiple sources, the cost of products sold may be affected by changes in the market price of materials and tariffs on certain materials, particularly imports from Asia, as well as disruptions in availability of raw materials, components, and sourced finished goods.

We do not currently engage in significant commodity hedging transactions for raw materials, though we have and will continue to commit to purchase certain materials for a period of up to 12 months. We monitor and investigate alternative suppliers and materials based on numerous attributes including quality, service, and price. We currently source raw materials and components from a number of suppliers, but our ongoing efforts to improve the cost effectiveness and availability of our products and services may result in a reduction in the number of our suppliers.

Intellectual Property

We own or have licenses to use various domestic and foreign patents, trademarks, and other intellectual property related to our products, processes, and businesses. These intellectual property rights are important factors for our businesses. We rely on copyright, patent, trade secret, and trademark laws as well as agreements, restrictive covenants, and internal processes and controls to protect these proprietary rights. Despite these protections, unauthorized parties may attempt to infringe on our intellectual property. As of August 31, 2021, we had approximately 2,600 active United States and foreign patents. While patents and patent applications in the aggregate are important to our competitive position, no single patent or patent application is individually material to us.

Seasonality and Cyclicality

Our business exhibits some seasonality, with net sales being affected by weather and seasonal demand on construction and installation programs, particularly during the winter months, as well as the annual budget cycles of major customers. Because of these seasonal factors we historically have experienced our highest sales in the last two quarters of each fiscal year; however, our seasonality has been meaningfully impacted by the COVID-19 pandemic.

Our lighting and building technology solutions are sold to customers in both the new construction as well as renovation and retrofit markets for residential and non-residential applications. The construction market is cyclical in nature and subject to changes in general economic conditions and fiscal policies. Sales volume has a major impact on our profitability. Economic downturns and the potential decline in key construction markets may have a material adverse effect on our net sales, operating income, and financial position.

The COVID-19 Pandemic

The COVID-19 pandemic has resulted in intermittent worldwide government restrictions on the movement of people, goods, and services resulting in increased volatility in and disruptions to global markets. We remain committed to prioritizing the health and well-being of our associates and their families and ensuring that we operate effectively. We have implemented policies to screen associates, contractors, and vendors for COVID-19 symptoms upon entering our manufacturing, distribution, and open-office facilities in the United States, Mexico, and other locations as permitted by law. We have also implemented one-way traffic flows, additional cleaning requirements for common spaces, mandatory face coverings, hand sanitizer stations, socially-distanced workspaces, and self-serve pay stations within our cafeterias to mitigate the spread of the virus. Additionally, we have required certain employees whose job functions can be performed remotely to work primarily from home. See further discussion of the health

and safety of our employees, including our response to the COVID-19 pandemic, below within the Human Capital section of this Item 1. Business.

The COVID-19 pandemic has had an adverse impact on our results of operations. The pandemic has caused reduced construction and renovation spending as well as a disruption in our supply chain for certain components, both of which negatively impacted our fiscal 2021 sales. In fiscal 2020 we experienced a limited number of temporary facility shutdowns due to government-mandated closures. Although our facilities are now open and new government-mandated restrictions have been gradually lifted, a resurgence in COVID-19 cases may lead to the reimposition of previously lifted business closure requirements, the imposition of new restrictions, or the issuance of new or revised local or national health guidance. We also continue to incur additional health and safety costs including expenditures for personal protection equipment and facility enhancements to maintain proper distancing guidelines issued by the Centers for Disease Control and Prevention. We have taken actions to reduce costs, including the realignment of headcount with current volumes, a limit on all non-essential employee travel, other efforts to decrease discretionary spending, and reductions in our real estate footprint. Additionally, we elected to defer certain employer payroll taxes as allowable under the Coronavirus Aid, Relief, and Economic Security Act (the "CARES" Act) signed into law on March 27, 2020. Half of these deferrals are due in December 2021, and the remaining deferrals are due in December 2022.

Although we have implemented significant measures to mitigate further spread of the virus, our employees, customers, suppliers, and contractors may continue to experience disruptions to business activities due to potential further government-mandated or voluntary shutdowns, general economic conditions, or other negative impacts of the COVID-19 pandemic. We are continuously monitoring the adverse effects of the pandemic and identifying steps to mitigate those effects. As the COVID-19 pandemic is continually evolving, we are uncertain of its ultimate duration and impact. See Part I, Item 1a. Risk Factors for further details regarding the potential impacts of the COVID-19 pandemic to our results of operations, financial position, and cash flows.

Human Capital

We employed approximately 13,000 associates at August 31, 2021, of which approximately 4,000 were employed in the United States and approximately 8,500 were employed in Mexico. Our remaining associates were employed in other international locations including Europe, Canada, and the Asia/Pacific region. Union recognition and collective bargaining arrangements in place or in process cover approximately 1,400 and 7,200 associates in the United States and Mexico, respectively. Arrangements related to approximately 600 associates in the United States will expire after the next fiscal year, and arrangements for approximately 6,800 associates in Mexico will expire within the next fiscal year, primarily due to annual negotiations of union contracts. We believe that we have strong relationships with both our unionized and non-unionized associates.

Growth and Development

A key pillar to attract, develop, and retain top talent is our focus on the growth and development of our associates. In fiscal 2021, we began a renewed focus on development through the creation of development plans for associates. We enhanced the Performance Management process to better align associate aspirations, interests, and experiences with the talent needs that enable the business. We have established quarterly check-in discussions between managers and associates to encourage more continuous performance feedback and improvement and to hold leaders accountable for creating an associate development culture. We provide self-learning resources to help associates expand their lighting, controls, and building management technical knowledge through Acuity Academy.

We are currently enhancing our career framework through our Global Career Architecture project. The focus of this project is to enable a culture that more effectively attracts, retains, rewards, and mobilizes talent. We expect this project to underpin many new initiatives in fiscal 2022, including several new development programs and tools aimed at helping both managers and associates respond to the desire to learn and grow.

Compensation and Benefits

We review our compensation and benefit plans annually to ensure that we are providing competitive, contemporary, and inclusive programs so we can attract and retain the best people and support the health and well-being of our associates and their families. Based on this review, we offer a competitive total rewards package to our associates that includes base compensation, bonuses, profit-sharing plans, stock grants, and/or retirement benefits commensurate with an employee's position, skill set, and experience.

Diversity, Equity, and Inclusion

We believe that diversity, equity, and inclusion are important factors in our ongoing success. Our goal is to ensure that all associates feel valued, respected, and accepted for their contributions regardless of their race, sex, religion, ethnicity, age, gender identity, disabilities, national origin, sexual orientation, or other unique characteristics. To promote diversity in the workplace, we have created a diversity, equity, and inclusion council that is responsible for setting our diversity strategy and creating a three-year roadmap of initiatives, many resulting from associate feedback. Our diversity, equity, and inclusion council consists of members of management as well as key human resource process leaders and leaders from our various employee resource groups. We currently have three employee resource groups: Minorities Amplifying Growth, Inclusion, and Community (“MAGIC”); the Women’s Network; and formed in fiscal 2021, People Respecting Identity, Diversity, and Equity (“PRIDE”). These groups are are designed to embrace, celebrate, and recognize the power of diversity.

Health and Safety

We strive to ensure our associates have a safe and collaborative work environment. Our management practices promote Environmental, Health & Safety (“EHS”) excellence. To achieve this standard, we have instituted an EHS Management System based on the goals and guidelines of the International Standards of Operation for Environmental Management, International Standards for Occupational Health & Safety Management, and our own guiding principles. These guidelines include identifying and controlling hazardous exposures for the prevention of injuries, preventing pollution, and complying with all relevant legal and other requirements. We use each facility’s Acuity Environmental Safety Scorecard (“AESS”) to provide visibility into the facility’s qualitative and quantitative results, with an emphasis on leading indicators that help avoid violations, accidents, and injuries. A variety of different metrics are averaged to determine a facility’s final score, which is used to rank each facility against other facilities and to find continuous improvement opportunities.

COVID-19 Response

We remain committed to prioritizing the health and well-being of our associates and their families in light of the COVID-19 pandemic. We have implemented policies to screen associates, contractors, and vendors for COVID-19 symptoms upon entering our manufacturing and distribution and open office facilities in the United States, Mexico, and other locations as permitted by law. We continue to follow guidelines issued by the World Health Organization, Centers for Disease Control and Prevention, and local health providers, adapting our policies and procedures quickly in response to continually evolving information, statistics, and best practices. During fiscal 2021, we required remote work for all whose jobs can be performed remotely and canceled significant in-person events or shifted them to virtual. We have expanded paid and unpaid leave policies to cover exposures, self-quarantines, and school closures that may impact our associates. At our manufacturing and distribution facilities, we have staggered and rotated shifts, changed traffic flows to limit interaction, provided additional hand sanitizing stations, installed plastic shields between workstations, and increased spacing at all work areas. We regularly clean work areas and encourage all associates to engage in good handwashing and hygiene practices. We also offer on-site vaccination clinics at several facilities and strongly encourage our associates to get vaccinated.

Environmental Sustainability

We are reducing the environmental impact of our products and solutions, driving efficient use of raw materials, and operating our facilities in an intelligent, environmentally friendly manner. During fiscal 2021, we established an executive-level Environmental, Social, and Governance (“ESG”) council to oversee our sustainability strategy across our business. Among other things, this council assesses risks and opportunities and guides activities related to climate change and other ESG matters. During fiscal 2021, we announced that the Company achieved 100 percent carbon neutrality in operations through a combination of carbon reduction and offsetting measures. We regularly communicate progress as part of our EarthLIGHT sustainability program.

Item 1a.Risk Factors

This filing contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. A variety of risks and uncertainties could cause our actual results to differ materially from the anticipated results or other expectations expressed in our forward-looking statements. See Cautionary Statement Regarding Forward-Looking Information included in Management's Discussion and Analysis of Financial Condition and Results of Operations. These risks could adversely impact our financial position, results of operations, cash flows, and financial expectations and could cause the market price of our common stock to decrease. Such risks include, without limitation:

Risks Related to Our Strategy

General business, political, and economic conditions, including the strength of the construction market, political events, or other factors may affect demand for our products and services.

We compete based on numerous factors, including features and benefits, brand name recognition, product quality, product and system design, energy efficiency, customer relationships, service capabilities, and price. In addition, we operate in a highly competitive environment that is influenced by a number of general business and economic factors, such as economic vitality, employment levels, credit availability, interest rates, trends in vacancy rates and rent values, energy costs, and commodity costs. Sales of lighting, lighting controls, and building technology solutions depend significantly on the level of activity in new construction and renovation/retrofits. Declines in general economic activity, appropriations, and regulations, including tax and trade policy and other political uncertainties, may negatively impact new construction and renovation projects, which in turn may impact demand for our product and service offerings.

Our business and results have been and may be adversely affected by fluctuations in the cost or availability of raw materials, components, purchased finished goods, or services.

We utilize a variety of raw materials and components in our production process including steel, aluminum, lamps, certain rare earth materials, LEDs, LED drivers, ballasts, wire, electronic components, power supplies, petroleum-based by-products, natural gas, and copper. We also source certain finished goods externally. During fiscal 2021, the COVID-19 pandemic has caused a disruption in our supply chain for certain components and resulted in higher prices for significant commodities, including oil and steel, as well as increased warehousing and container costs, which has negatively impacted our business. Future increases in our costs and/or continued disruptions in the supply or could negatively impact our profitability, as there can be no assurance that future price increases will be successfully passed through to customers. We generally source these goods from a number of suppliers. However, there are a limited number of suppliers for certain components and certain purchased finished goods, which on a limited basis results in sole-source supplier situations.

Suppliers for certain of those items are our competitors that may, for various strategic reasons, choose to cease selling to us. In addition, our ongoing efforts to improve the cost effectiveness of our products and services may result in a reduction in the number of our suppliers, and in turn, increased risk associated with reliance on a single or limited number of suppliers. Furthermore, volatility in certain commodities, such as oil, impacts all suppliers and, therefore, may result in additional price increases from time to time regardless of the number and availability of suppliers. Profitability and volume could be negatively impacted by limitations inherent within the supply chain of certain of these component parts, including competitive, governmental, and legal limitations, natural disasters, and other events that could impact both supply and price. Additionally, we are dependent on certain service providers for key operational functions. While there are a number of suppliers of these services, the cost to change service providers and set up new processes could be significant.

Our results may be adversely affected by our inability to maintain pricing.

Aggressive pricing actions by competitors may affect our ability to achieve desired revenue growth and profitability levels under our current pricing strategies. We may also decide to lower prices to match the competition or for other reasons or to exit unprofitable business. Additionally, we may not be able to increase prices to cover rising costs. Even if we were able to increase prices to cover costs, competitive pricing pressures may not allow us to pass on any more than the cost increases. Alternatively, if costs were to decline, the marketplace may not allow us to hold prices at their current levels.

Our inability to effectively introduce new products and solutions could adversely affect our ability to compete.

Continual introductions of new products and solutions, services, and technologies, enhancement of existing products and services, and effective servicing of customers are key to our competitive strategy. The success of new product and solution introductions depends on a number of factors, including, but not limited to, timely and successful product development, product quality, market acceptance, our ability to manage the risks associated with product life cycles, such as additional inventory obsolescence risk as product life cycles begin to shorten, new products and production capabilities, effective management of purchase commitments and inventory levels to support anticipated product manufacturing and demand, availability of products in appropriate quantities and costs to meet anticipated demand, and risk that new products may have quality or other defects in the early stages of introduction. Accordingly, we cannot fully predict the ultimate effect of new product introductions on our business, Additionally, new products and solutions may not achieve the same profit margins as expected and as compared to our historic products and solutions. Furthermore, other market participants, such as a well-established competitors, could develop alternative platforms for monetizing products, solutions, and services that result in a paradigm shift in our industry, particularly with respect to new and developing technologies.

We may pursue future growth through acquisitions, alliances, or investments, which may not yield anticipated benefits.

We have strengthened our business through acquisitions, alliances, and investments and may continue to do so as opportunities arise in the future. Such investments have been and may be in start-up or development stage entities. We will benefit from such activity only to the extent that we can effectively leverage and integrate the assets or capabilities of the acquired businesses and alliances, including, but not limited to, personnel, technology, and operating processes. Moreover, unanticipated events, negative revisions to valuation assumptions and estimates, diversion of resources and management's attention from other business concerns, and difficulties in attaining synergies, among other factors, could adversely affect our ability to recover initial and subsequent investments, particularly those related to acquired goodwill and intangible assets or non-controlling interests. In addition, such investment transactions may limit our ability to invest in other activities, which could be more profitable or advantageous.

The inability to effectively execute our business strategies could adversely affect our financial condition and results of operations.

Various uncertainties and risks are associated with the implementation of a number of aspects of our global business strategies, including but not limited to, the development, marketing and selling of new products and solutions; new product development; the development, marketing, and selling of lighting, building technology, and software-based solutions; effective integration of acquisitions; and our environmental strategies and climate change commitments. Those uncertainties and risks include, but are not limited to: diversion of management’s attention; difficulty in retaining or attracting employees; negative impact on relationships with distributors and customers; obsolescence of current products and slow new product development; inability to effectively participate in opportunities utilizing our digital lighting and building technology systems; additional streamlining efforts; inability to produce certain components with quality, performance, and cost attributes equal to or better than provided by other component manufacturers; and unforeseen difficulties in the implementation of the management operating structure. Problems with strategy execution could offset anticipated benefits, disrupt service to customers, and impact product quality as well as adversely affect our business and reputation. With the addition of new products and solutions, we may encounter new and different competitors that may have more experience with respect to such products and solutions.

We may experience difficulties in streamlining activities, which could impact shipments to customers, product quality, and the realization of expected savings from streamlining actions.

We expect to benefit from our programs to streamline operations, including the consolidation of certain facilities and the reduction of overhead costs. Such benefits will only be realized to the extent that we can effectively leverage assets, personnel, and operating processes in the transition of production between manufacturing facilities. Uncertainty is inherent within the facility consolidation process and unforeseen circumstances could offset the anticipated benefits, disrupt service to customers, and impact product quality.

Risks Related to Our Operations

The COVID-19 pandemic could have a material adverse effect on our ability to operate, results of operations, financial condition, liquidity, and capital investments.

The World Health Organization has declared the COVID-19 outbreak a pandemic, and the virus continues to spread in areas where we operate and sell our products and services. The COVID-19 pandemic and similar issues in the future could have a material adverse effect on our ability to operate, results of operations, financial condition, liquidity, and capital investments. Several public health organizations have recommended, and some governments have implemented, certain measures to slow and limit the transmission of the virus, including shelter in place, social distancing ordinances, and business shutdowns. There is considerable uncertainty regarding the extent to which the COVID-19 outbreak will continue to spread, including the impact of identified and potential new variants, the extent and duration of governmental and other measures implemented to try to slow the spread of the virus, and public response to the pandemic.

The pandemic and such preventive measures, or others required or that we may voluntarily put in place, may have a material adverse effect on our business for an indefinite period of time, such as the potential shut down of certain locations; decreased employee availability; increased claims or other expenses; potential border closures; disruptions to the businesses of our channel partners; and others. We may incur additional costs related to additional testing and screening of our employees, governmental vaccination mandates, and additional safety requirements from organizations such as OSHA. Our suppliers and customers have also faced these and other challenges, which has led to a disruption in our supply chain for certain components, decreased construction and renovation spending and consumer demand for our products and services, rising commodity costs, and increased freight, warehousing, and container costs. These disruptions and challenges may continue for an indefinite period of time and may also materially affect our future access to our sources of liquidity, particularly our cash flows from operations, financial condition, capitalization, and capital investments. Additionally, the effects of COVID-19 on the global economy could adversely affect our ability to access the capital and other financial markets, and if so, we may need to consider alternative sources of funding for some of our operations and for working capital, which may increase our cost of, as well as adversely impact our access to, capital. These uncertain economic conditions may also result in the inability of our customers and other counter-parties to make payments to us, on a timely basis or at all.

Although these disruptions may continue to occur, the long-term economic impact and near-term financial impacts of the COVID-19 pandemic, including but not limited to, possible impairment, restructuring, and other charges, cannot be reliably quantified or estimated at this time due to the uncertainty of future developments.

Technological developments and increased competition could affect our operating profit margins and sales volume.

We compete in an industry and markets where technology and innovation play major roles in the competitive landscape. We are highly engaged in the investigation, development, and implementation of new technologies and services. Securing employee talent, key partnerships, and alliances, including having access to technologies, services, and solutions developed by others, as well as obtaining appropriate patents and the right to utilize patents of other parties all play a significant role in protecting our freedom to operate. Additionally, the continual development of new technologies by existing and new source suppliers — including non-traditional competitors with significant resources — looking for either direct market access or partnerships with competing large manufacturers, coupled with significant associated exclusivity and/or patent activity, could adversely affect our ability to sustain operating profit margins and desirable levels of sales volume.

In addition, there are new competitors, including small startup companies and global electronics, technology, and software companies, offering competing solutions, sometimes deploying different technologies. These competitors may vertically integrate and begin offering total solution packages that directly compete with our offerings. Certain global and more diversified electrical manufacturers as well as certain global technology and building solution providers may be able to obtain a competitive advantage, either through internal development or acquisitions, over us by offering broader and more integrated solutions utilizing electrical, lighting, controls, building automation systems, and data analytics, and small startup companies may offer more localized product sales and support services within individual regions.

We may be unable to sustain significant customer and/or channel partner relationships.

Relationships with customers are directly impacted by our ability to deliver quality products and services. Although no individual customer exceeded 10% of sales during the fiscal 2021, the loss of or a substantial decrease in the

10

Table of Contents

volume of purchases by certain larger customers could harm our business in a meaningful manner. We have relationships with channel partners such as electrical distributors, home improvement retailers, independent sales agencies, system integrators, and value-added resellers. While we maintain positive, and in many cases long-term, relationships with these channel partners, the sudden or unplanned loss of a number of these channel partners or a substantial decrease in the volume of purchases from a major channel partner or a group of channel partners could adversely affect our business.

We could be adversely affected by disruptions to our operations.

The breakdown of equipment or other events, including, but not limited to, labor disputes, strikes, workplace violence, pandemics, climate change, brown outs and other power outages, water scarcity, cyber-attacks, civil disruptions, or catastrophic events such as war or natural disasters, leading to production interruptions in our or one or more of our suppliers’ facilities could adversely affect us. Approximately 55% of our finished products are manufactured in Mexico, a country that periodically experiences heightened civil unrest or may experience trade disputes with the U.S., both of which could cause a disruption of the supply of products to or from these facilities. Further, because many of our customers are to varying degrees dependent on planned deliveries from our facilities, those customers that have to reschedule their own production or delay opening a facility due to our missed deliveries as a result of these disruptions could pursue financial claims against us. We may incur costs to correct any of these problems in addition to facing claims from customers. Further, our reputation among actual and potential customers may be harmed and result in a loss of business. While we have developed business continuity plans, including alternative capacity, to support responses to such events or disruptions and maintain insurance policies covering, among other things, physical damage and business interruptions, these policies may not cover all losses. We could incur uninsured losses and liabilities arising from such events, including damage to our reputation, loss of customers, and substantial losses in operational capacity.

Company operating systems, information systems, or devices may experience a failure, a compromise of security, or a violation of data privacy laws or regulations, which could adversely impact our operations as well as the effectiveness of internal controls over operations and financial reporting.

We are highly dependent on various software and automated systems to record and process operational and financial transactions. We could experience a failure of one or more of these software and automated systems or could fail to complete all necessary data reconciliation or other conversion controls when implementing a new software system. We could also experience a compromise of our security due to many reasons, including technical system flaws, clerical, data input or record-keeping errors, or tampering or manipulation of our systems by employees or unauthorized third parties, including viruses, malware, or phishing. Information security risks also exist with respect to the use of portable electronic devices, such as laptops and smartphones, which are particularly vulnerable to loss and theft. We may also be subject to disruptions of any of these systems arising from events that are wholly or partially beyond our control (for example, natural disasters, acts of terrorism, cyber attacks, including but not limited to ransomware attacks, epidemics, computer viruses, and electrical/telecommunications outages). All of these risks are also applicable where we rely on outside vendors to provide services, which may operate in a cloud environment. We are dependent on third-party vendors to operate secure and reliable systems which may include data transfers over the internet.

We also provide and maintain technology to enable lighting controls and building technology systems. In addition to the risks noted above, there are other risks associated with these customer offerings. For example, a customer may depend on integral information from, or functionality of, our technology to support that customer’s other systems, such that a failure of our technology could impact those systems, including by loss or destruction of data. Likewise, a customer’s failure to properly configure, update, segregate, or upgrade its own network and integrations with our technology are outside of our control and could result in a failure in functionality or security of our technology.

Certain of our third-party vendors and we may receive and store personal information in connection with human resources operations, customer offerings, and other aspects of the business. A material network breach in the security of these systems could include the theft of intellectual property, trade secrets, the unauthorized release, gathering, monitoring, misuse, loss, change, or destruction of our or our clients' confidential, proprietary and other information (including personal identifying information of individuals), or otherwise disrupt our or our clients' or other third parties' business operations. To the extent that any disruption or security breach results in a loss or damage to our data, or an inappropriate disclosure of confidential or customer or employee information, it could cause significant damage to our reputation, affect relationships with our customers, employees, and other counterparties, lead to claims against us, which may result in the payment of fines, penalties, and costs, and ultimately harm our business. In addition, we may be required to incur significant costs, or regulatory fines, penalties, or intervention, to protect against damage caused by these disruptions or security breaches in the future.

11

Table of Contents

We are also subject to an increasing number of data privacy and security laws and regulations that impose requirements on us and our technology prior to certain use or transfer, storing, use, processing, disclosure, and protection of data and prior to sale or use of certain technologies. Failure to comply with such laws and regulations could result in the imposition of fines, penalties and other costs. The legal and regulatory data privacy framework is evolving and uncertain. For example, the European Court of Justice’s decision in October 2015 to invalidate the Safe Harbor data privacy program between the United States and the implementation of Data Protection Commission v. Facebook Ireland, Schrems (aka Schrems II) as well as the new and proposed privacy and security laws around the world all could disrupt our ability to use or transfer data or sell products and solutions because such activities may not be in compliance with applicable law in certain jurisdictions.

System failures, ineffective system implementation or disruptions, failure to comply with data privacy and security laws or regulations, or the compromise of security with respect to internal or external systems or portable electronic devices could damage our systems or infrastructure, subject us to liability claims, or regulatory fines, penalties, or intervention, harm our reputation, interrupt our operations, disrupt customer operations, and adversely affect our internal control over financial reporting, business, financial condition, results of operations, or cash flows.

Changes in our relationship with employees, changes in U.S. or international employment regulations, an inability to attract and retain talented employees, or a loss of key employees could adversely impact the effectiveness of our operations.

We employed approximately 13,000 people as of August 31, 2021, approximately 9,000 of whom are employed in international locations. As such, we have significant exposure to changes in domestic and foreign laws governing relationships with employees, including wage and hour laws and regulations, fair labor standards, minimum wage requirements, overtime pay, unemployment tax rates, workers' compensation rates, citizenship requirements, and payroll taxes, which likely would have a direct impact on our operating costs. Union recognition and collective bargaining agreements are in place or in process covering approximately 66% of our workforce. Collective bargaining agreements representing approximately 57% of our workforce will expire within one year, primarily due to annual negotiations with unions in Mexico. While we believe that we have good relationships with both our unionized and non-unionized employees, we may become vulnerable to a strike, work stoppage, or other labor action by these employees.

We rely upon the knowledge and experience of employees involved in functions throughout the organization that require technical expertise and knowledge of the industry. An inability to attract and retain such employees could adversely impact our ability to execute key operational functions.

There are inherent risks in our solutions and services businesses.

Risks inherent in the sale of solutions and services include assuming greater responsibility for successfully delivering projects that meet a particular customer specification, including: defining and controlling contract scope and timing, efficiently executing projects, and managing the performance and quality of subcontractors and suppliers. As we expand our service offerings, reliance on the technical infrastructure to provide services to customers will increase. If we fail to appropriately manage and secure the technical infrastructure required, customers could experience service outages or delays in implementation of services. If we are unable to manage and mitigate these risks, we could incur liabilities and other losses.

We may be subject to risk in connection with third-party relationships necessary to operate our business.

We utilize strategic partners and third-party relationships in order to operate and grow our business. For instance, we utilize third parties to contract manufacture certain products, subcontract installation and commissioning, as well as perform certain selling, distribution, and administrative functions. We cannot control the actions or performance, including product quality, of these third parties and therefore, cannot be certain that we or our end-users will be satisfied. Any future actions of or any failure to act by any third party on which our business relies could cause us to incur losses or interruptions in our operations.

We are subject to risks related to operations and suppliers outside the United States.

We have substantial activities outside of the United States, including sourcing of products, materials, components, and contract manufactured finished goods, as well as manufacturing and distribution activities. Our operations, as well as those of key vendors, are therefore subject to regulatory, economic, political, military, and other events in countries where these operations are located. In addition to the risks that are common to both our domestic and international operations, we face risks specifically related to our foreign operations and sourcing activities, including but not limited to: foreign currency fluctuations; unstable political, social, regulatory, economic, financial, and market

12

Table of Contents

conditions; laws that prohibit shipments to certain countries or restricted parties and that prohibit improper payments to government officials such as the Foreign Corrupt Practices Act and the U.K. Bribery Act; potential for privatization and other confiscatory actions; trade restrictions and disruption; shipping delays or disruptions; criminal activities; increases in tariffs and taxes; corruption; and other changes in regulation in international jurisdictions that could result in substantial additional legal or compliance obligations for us.

We source certain components and approximately 16% of our finished goods from Asia, a significant portion of which are subject to import tariffs. These tariffs could increase in future periods resulting in higher costs and/or lower demand. We are seeking to mitigate the impact of Chinese tariffs on our profitability, including a variety of activities such as engaging alternative suppliers that produce products and components whose origin is in countries other than China, insourcing the production of certain products, and raising selling prices. We could be adversely affected to the extent we are unable to mitigate the impacts of the tariffs.

We operate seven manufacturing facilities in Mexico, some of which are authorized to operate as Maquiladoras by the Ministry of Economy of Mexico. Maquiladora status allows us to import raw materials into Mexico duty-free, provided that such items, after processing, are exported from Mexico within a stipulated time frame. Maquiladora status, which is renewed periodically, is subject to various restrictions and requirements, including compliance with the terms of the Maquiladora program and other local regulations, which have become stricter in recent years. In addition, if our Mexican facilities cease to qualify for Maquiladora status or if the Mexican government adopts additional adverse changes to the program, our manufacturing costs in Mexico would increase.

We are also subject to certain other laws and regulations affecting our international operations, including laws and regulations such as the United States, Mexico, Canada Free Trade Agreement (“USMCA”) which, among other things, provide certain beneficial duties and tariffs for qualifying imports and exports, subject to compliance with the applicable classification and other requirements. A majority of our sales are subject to USMCA. In addition, the US government has initiated or is considering imposing tariffs on certain foreign goods, including steel and aluminum. Related to this action, certain foreign governments, including China, have instituted or are considering imposing tariffs on certain U.S. goods. We source certain components and approximately 16% of our finished goods from Asia, a significant portion of which are subject to Chinese tariffs. It remains unclear what the U.S. Administration or foreign governments will or will not do with respect to tariffs, the recently enacted USMCA, or other international trade agreements and policies. A trade war or other governmental action related to tariffs or international trade agreements or policies has the potential to adversely impact demand for our products, costs, customers, suppliers, and/or the US economy or certain sectors thereof and, thus, to adversely impact our business.

The evolution of our products, complexity of our supply chain, and reliance on third-party vendors such as customs brokers and freight vendors, which may not have effective processes and controls to enable us to fully and accurately comply with such requirements, could subject us to liabilities for past, present, or future periods. Such liabilities could adversely impact our business.

We continue to monitor conditions affecting our international locations, including potential changes in income from a strengthening or weakening in foreign exchange rates in relation to the U.S. dollar. Some of these risks, including but not limited to foreign exchange rates, violations of laws, and higher costs associated with changes in regulation, could adversely impact our business.

Risks Related to Legal and Regulatory Matters

Failure to comply with the broad range of standards, laws and regulations in the jurisdictions in which we operate may result in exposure to substantial disruptions, costs and liabilities.

The laws and regulations impacting us impose increasingly complex, stringent, and costly compliance activities, including but not limited to environmental, health, and safety protection standards and permitting, labeling, and other requirements regarding, among other things, electronic and wireless communications, air emissions, wastewater discharges, the use, handling, and disposal of hazardous or toxic materials, remediation of environmental contamination, and working conditions for and compensation of our employees. In addition, permits and environmental controls are required for certain of our operations to limit air and water pollution, and these permits are subject to modification, renewal, and revocation by issuing authorities. Some environmental laws, such as Superfund, the Clean Water Act, and comparable laws in U.S. states and other jurisdictions world-wide, impose joint and several liability for the cost of environmental remediation, natural resource damages, third-party claims, and other expenses, without regard to the fault or the legality of the original conduct, on those persons who contributed to the release of a hazardous substance into the environment. Environmental laws and regulations have generally become stricter in recent years, and federal, state, and local governments domestically and internationally are considering new laws and regulations, including those governing raw material composition, carbon dioxide and

13

Table of Contents

other air emissions, end-of-life product dispositions, and energy efficiency. We may be affected by those or other future standards, laws or regulations, including those imposed in response to energy, climate change, our carbon footprint, product functionality, geopolitical, corporate social responsibility, or similar concerns. These standards, laws, or regulations may impact our costs of operation, the sourcing of raw materials, and the manufacture and distribution of our products and place restrictions and other requirements or impediments on the products and solutions we can sell in certain geographical locations or on the willingness of certain investors to own our shares.

We may develop unexpected legal contingencies or matters that exceed insurance coverage.

We are subject to and in the future may be subject to various claims, including legal claims arising in the normal course of business. Such claims may include without limitation employment claims, product recall, personal injury, network security, data privacy, or property damage claims resulting from the use of our products, services, or solutions, as well as exposure to hazardous materials, contract disputes, or intellectual property disputes. We are insured up to specified limits for certain types of losses with a self-insurance retention per occurrence, including product or professional liability, and cyber liability, including network security and data privacy claims, and are fully self-insured for certain other types of losses, including environmental, product recall, warranties, commercial disputes, and patent infringement. We establish accruals for legal claims when the costs associated with the claims become probable and can be reasonably estimated. The actual costs of resolving legal claims may be substantially higher or lower than the level of insurance coverage we hold and/or the amounts accrued for such claims. In the event of unexpected future developments, it is possible that the ultimate resolutions of such matters could be unfavorable. Our insurance coverage is negotiated on an annual basis, and insurance policies in the future may have coverage exclusions that could cause claim-related costs to rise.

If our products are improperly designed, manufactured, packaged, or labeled, or are otherwise alleged to cause harm or injury, we may need to recall those items, may have increased warranty costs, and could be the target of product liability claims.

We may need to recall products if they are improperly designed, manufactured, packaged, or labeled, and we do not maintain insurance for such recall events. Many of our products and solutions have become more complex in recent years and include more sophisticated and sensitive electronic components. A problem or issue relating to any individual component could have the effect of creating a compounded problem for an integrated solution, which could result in significant costs and losses. We have increasingly manufactured certain of those components and products in our own facilities. We have previously initiated product recalls as a result of potentially faulty components, assembly, installation, design, and packaging of our products. Widespread product recalls could result in significant losses due to the costs of a recall, the destruction of product inventory, penalties, and lost sales due to the unavailability of a product for a period of time. In addition, products we developed that incorporate technologies, such as LED, generally provide for more extensive warranty protection which may result in higher costs if warranty claims on these products are higher than historical amounts. We may also be liable if the use or failure of any of our products cause harm, whether from fire, shock, harmful materials or components, alleged adverse health impacts from exposure to light emitted by our products, or any other personal injury or property damage, and we could suffer losses from a significant product liability judgment against us in excess of our insurance limits. We may not be able to obtain indemnity or reimbursement from our suppliers or other third parties for the warranty costs or liabilities associated with our products. A significant product recall, warranty claim, or product liability case could also result in adverse publicity, damage to our reputation, and a loss of consumer confidence in our products.

We may not be able to adequately protect our intellectual property and could be the target of intellectual property claims.

We own certain patents, trademarks, copyrights, trade secrets, and other intellectual property. In addition, we continue to file patent applications, when appropriate. We cannot be certain that others have not and will not infringe on our intellectual property rights; however, we seek to establish and protect those rights, which could result in significant legal expenses and adversely affect our financial condition and results of operations.

Over the last several years, we and others in the industry have received an increased number of allegations of patent infringement from competitors and from non-practicing entity patent holders, often coupled with offers to license such patents for our use. Such offers typically relate to various technologies including electronics, power systems, controls, and software, as well as the use of visible light to communicate data, the use of certain wireless networking methods, and the design of specific products. We believe that we do not need or will be able to invalidate or access such patents through licensing, cross-licensing, or other mutually beneficial arrangements, although to the extent we are required but unable to enter into such arrangements on acceptable economic terms, it could adversely impact us.

Risks Related to Financial Matters

The market price and trading volume of our shares may be volatile.

The market price of our common shares could fluctuate significantly for many reasons, including reasons unrelated to our specific performance, such as reports by industry analysts, investor perceptions, or negative announcements by customers, competitors, or suppliers regarding their own performance, as well as general global economic, industry, and political conditions. Our performance could be different than analyst expectations causing a decline in our stock price. To the extent that other large companies within our industry experience declines in share price, our share price may decline as well. In addition, when the market price of a company’s shares drops significantly, shareholders could institute securities class action lawsuits against us or otherwise engage in activism, which could cause us to incur substantial costs and could divert the time and attention of our management and other resources.

Changes to LIBOR may adversely impact the interest rate paid on some of our loans and consequently, our earnings and cash flows.

The borrowing facilities under our Credit Agreement (defined in the Debt and Lines of Credit note within the Notes to Consolidated Financial Statements) currently allow us to incur variable debt that is indexed to the London Inter-Bank Offered Rate (“LIBOR”) or an alternate base rate plus an applicable margin. On July 27, 2017, the U.K. Financial Conduct Authority, which regulates LIBOR, announced that it will phase out rates for the calculation of LIBOR. As a result of this change, certain LIBOR tenors and currencies will be eliminated by the end of calendar 2021 with all other tenors and currencies of LIBOR eliminated by the end of June 2023. Although there are potential reference rate replacements for LIBOR, it is not possible to predict what rate or rates may become accepted alternatives to LIBOR for certain securities, loans, and liabilities, or the effect of these alternatives on the value of securities whose interest rates are tied to LIBOR. Even though our current Credit Agreement expires prior to the final phase out of LIBOR tenors and currencies, the consequences of the phase out of LIBOR cannot be predicted on any potential cessation, modification, renewal, or new credit agreement we may execute. As a result, our future interest expense may increase, our ability to refinance some or all of our existing indebtedness may be impacted, and our available cash flow may be adversely affected.

Risks related to our defined benefit retirement plans may adversely impact results of operations and cash flows.

Significant changes in actual investment returns on defined benefit plan assets, discount rates, and other factors could adversely affect our comprehensive income and the amount of contributions we are required to make to the defined benefit plans in future periods. As our defined benefit plan assets and liabilities are marked-to-market on an annual basis, large non-cash gains or losses could be recorded in the fourth quarter of each fiscal year. In accordance with United States generally accepted accounting principles, the income or expense for the plans is calculated using actuarial valuations. These valuations reflect assumptions about financial markets and interest rates, which may change based on economic conditions. Funding requirements for the defined benefit plans are dependent upon, among other things, interest rates, underlying asset returns, and the impact of legislative or regulatory changes related to defined benefit funding obligations. Unfavorable changes in these factors could adversely affect our results.

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

Our common stock is listed on the New York Stock Exchange under the symbol “AYI.” At October 22, 2021, there were 1,948 stockholders of record. The information required by this item with respect to equity compensation plans is included under the caption Equity Compensation Plans in our proxy statement for the annual meeting of stockholders to be held January 5, 2022, which we will file with the Securities and Exchange Commission pursuant to Regulation 14A. The proxy statement is incorporated herein by reference.

Issuer Purchases of Equity Securities

In March 2018, the Board of Directors (the “Board”) authorized the repurchase of up to six million shares of our common stock. As of October 22, 2020, 2.2 million shares were available for repurchase under this authorization. On October 23, 2020, the Board authorized the repurchase of an additional 3.8 million shares of our common stock, bringing our total authorization back to six million shares at that time. Under the new increased share repurchase authorization, we may repurchase shares of our common stock from time to time at prevailing market prices, depending on market conditions, through open market or privately negotiated transactions. No date has been established for the completion of the share repurchase program, and we are not obligated to repurchase any shares. Subject to applicable corporate securities laws, repurchases may be made at such times and in such amounts as management deems appropriate. Repurchases under the program can be discontinued at any time management feels additional repurchases are not warranted.

As of August 31, 2021, the maximum number of shares that may yet be repurchased under the share repurchase program authorized by the Board equaled 3.8 million shares. The following table summarizes share repurchase activity by month for the quarter ended August 31, 2021:

We are a market-leading industrial technology company. Through our two business segments, Acuity Brands Lighting and Lighting Controls (“ABL”) and the Intelligent Spaces Group (“ISG”) we design, manufacture, and bring to market products and services that make the world more brilliant, productive, and connected. We achieve growth through the development of innovative new products and services, including lighting, lighting controls, building management systems, and location-aware applications.

We achieve customer-focused efficiencies that allow us to increase market share and deliver superior returns. We look to aggressively deploy capital to grow the business and to enter attractive new verticals.

Capital Resources and Liquidity

We have numerous sources of capital, including cash on hand and cash flows generated from operations as well as various sources of financing. Our ability to generate sufficient cash flow from operations or to access certain capital markets, including banks, is necessary to meet our capital allocation priorities, which are to reinvest in our organic growth, make strategic acquisitions and investments, pay dividends, and repurchase shares. Sufficient cash flow generation is also critical to fund our operations in the short and long-term, to make required contributions to our employee benefit plans, and to maintain compliance with covenants contained in our financing agreements. We believe that we will be able to meet our liquidity needs over the next 12 months based on our cash on hand, current projections of cash flows from operations, and borrowing availability under financing arrangements. Additionally, we believe that our cash flows from operations and sources of funding, including, but not limited to, future borrowings and borrowing capacity, will sufficiently support our long-term liquidity needs. In the event of a sustained market deterioration, we may need additional capital, which would require us to evaluate available alternatives and take appropriate actions.

Cash

Our cash position at August 31, 2021 was $491.3 million, a decrease of $69.4 million from August 31, 2020. Cash generated from operating activities, cash on-hand, and additional long-term debt borrowings were used during the current year to fund our capital allocation priorities as discussed below.

We generated $408.7 million of cash flows from operating activities during fiscal 2021 compared with $504.8 million in the prior-year period, a decrease of $96.1 million, due primarily to increased operating working capital requirements to support the improvement in year-over-year sales as well as higher payments for income taxes, partially offset by payroll tax deferrals under the Coronavirus Aid, Relief, and Economic Security Act of 2020 and lower interest payments on long-term borrowings due to timing.

Our significant contractual cash requirements as of August 31, 2021 include principal and interest on long-term debt as well as payments for operating lease liabilities. Our obligations related to these items are outlined in the Debt and Lines of Credit and Leases footnotes of the Notes to Consolidated Financial Statements within this Form 10-K. Additionally, we incur purchase obligations in the ordinary course of business that are enforceable and legally binding. Contractual purchase obligations for years subsequent to August 31, 2021 include $451.1 million in fiscal 2022. Contractual purchase obligations beyond fiscal 2022 are not significant.

Financing Arrangements

During fiscal 2021, we received proceeds of $493.8 million through debt issuances and repaid $401.1 million of previously outstanding long-term debt, resulting in net proceeds of $92.7 million. See the Debt and Lines of Credit footnote of the Notes to Consolidated Financial Statements for discussion of our various financing arrangements, including the terms of our $400.0 million five-year unsecured revolving credit facility (“Revolving Credit Facility”) as well as the $500.0 million aggregate principal amount of 2.150% senior unsecured notes due December 15, 2030 (the “Unsecured Notes”). At August 31, 2021, our outstanding debt balance was $494.3 million compared to our cash position of $491.3 million. We were in compliance with all financial covenants under our financing arrangements as of August 31, 2021.

At August 31, 2021, we had additional borrowing capacity under the revolving credit facility of $395.9 million under the most restrictive covenant in effect at the time, which represents the full amount of the facility less the outstanding letters of credit of $4.1 million issued under the facility. As of August 31, 2021, our cash on hand combined with the additional borrowing capacity under the revolving credit facility totaled approximately $0.9 billion.

The Unsecured Notes were issued by Acuity Brands Lighting, Inc., a wholly-owned subsidiary of Acuity Brands, Inc. The Unsecured Notes are fully and unconditionally guaranteed on a senior unsecured basis by Acuity Brands, Inc. and ABL IP Holding LLC, a wholly-owned subsidiary of Acuity Brands, Inc. The following tables present summarized financial information for Acuity Brands, Inc., Acuity Brands Lighting, Inc., and ABL IP Holding LLC on a combined basis after the elimination of all intercompany balances and transactions between the combined group as well as any investments in non-guarantors as of the dates and during the period presented (in millions):

Capital Allocation Priorities

Effective capital allocation is a key driver of stockholder value. Our capital allocation priorities are to invest in our business for growth, to invest in mergers and acquisitions, to maintain our dividend, and to make share repurchases.

Organic Growth Investments

We invested $43.8 million and $54.9 million in fiscal 2021 and 2020, respectively, in property, plant, and equipment, primarily related to investments in tooling, new and enhanced information technology capabilities, equipment, and facility enhancements. We currently expect to invest approximately 1.5% of net sales on capital expenditures during fiscal 2022.

Strategic Acquisitions and Investments

We seek opportunities to strategically expand and enhance our portfolio of solutions. We invested in acquisitions of businesses, net of cash acquired, of $75.3 million and $303.0 million in fiscal 2021 and 2020, respectively. These acquisitions primarily included the following transactions:

•On July 1, 2021, using cash on hand, we acquired certain assets and liabilities of ams OSRAM’s North American Digital Systems (“OSRAM DS”) business. This acquisition is intended to enhance our light emitting diode (“LED”) driver and controls technology portfolio and accelerate our innovation, expand our access to market through a more fulsome OEM product offering, and give us more control over our supply chain.

Table of Contents

•On May 18, 2021, using cash on hand, we acquired all of the equity interests of Rockpile Ventures, an accelerator of edge artificial intelligence startups. Rockpile Ventures helps early-stage artificial intelligence companies drive co-engineering and co-selling partnerships with major cloud ecosystems, enabling faster adoption from proof-of-concept trials to market scale.

•On September 17, 2019, using cash on hand and borrowings under available existing credit arrangements at that time, we acquired all of the equity interests of The Luminaires Group (“TLG”), a leading provider of specification-grade luminaires for commercial, institutional, hospitality, and municipal markets, all of which complement our dynamic lighting portfolio. TLG’s indoor and outdoor lighting fixtures are marketed to architects, landscape architects, interior designers, and engineers through five niche lighting brands: A-lightTM, CycloneTM, Eureka®, Luminaire LEDTM, and Luminis®.

•On November 25, 2019, using cash on hand, we acquired all of the equity interests of LocusLabs, Inc (“LocusLabs”). The LocusLabs software platform supports navigation applications used on mobile devices, web browsers, and digital displays in airports, event centers, multi-floor office buildings, and campuses.

Please refer to the Acquisitions footnote of the Notes to Consolidated Financial Statements for more information.

Dividends

We paid dividends on our common stock of $19.1 million ($0.52 per share) in fiscal 2021 and $20.8 million ($0.52 per share) in fiscal 2020, indicating a quarterly dividend rate of $0.13 per share. All decisions regarding the declaration and payment of dividends are at the discretion of the Board of Directors (the “Board”) and are evaluated regularly in light of our financial condition, earnings, growth prospects, funding requirements, applicable law, and any other factors the Board deems relevant.

Share Repurchases

During fiscal 2021, we repurchased 3.8 million shares of our outstanding common stock for $434.9 million. As of August 31, 2021, the maximum number of shares that may yet be repurchased under the share repurchase program authorized by the Board equaled 3.8 million shares. We expect to repurchase shares on an opportunistic basis subject to various factors including stock price, Company performance, market conditions, and other possible uses of cash.

The COVID-19 Pandemic

The COVID-19 pandemic has resulted in intermittent worldwide government restrictions on the movement of people, goods, and services resulting in increased volatility in and disruptions to global markets. We remain committed to prioritizing the health and well-being of our associates and their families and ensuring that we operate effectively. We have implemented policies to screen associates, contractors, and vendors for COVID-19 symptoms upon entering our manufacturing, distribution, and open-office facilities in the United States, Mexico, and other locations as permitted by law. We have also implemented one-way traffic flows, additional cleaning requirements for common spaces, mandatory face coverings, hand sanitizer stations, socially-distanced workspaces, and self-serve pay stations within our cafeterias to mitigate the spread of the virus. Additionally, we have required certain employees whose job functions can be performed remotely to work primarily from home.

The COVID-19 pandemic has had an adverse impact on our results of operations. The pandemic has caused reduced construction and renovation spending as well as a disruption in our supply chain for certain components, both of which negatively impacted our fiscal 2021 sales. In fiscal 2020 we experienced a limited number of temporary facility shutdowns due to government-mandated closures. Although our facilities are open and government-mandated restrictions have been gradually lifted, a resurgence in COVID-19 cases may lead to the reimposition of previously lifted business closure requirements, the imposition of new restrictions, or the issuance of new or revised local or national health guidance. We also continue to incur additional health and safety costs including expenditures for personal protection equipment and facility enhancements to maintain proper distancing guidelines issued by the Centers for Disease Control and Prevention. We have taken actions to reduce costs, including the realignment of headcount with current volumes, a limit on all non-essential employee travel, other efforts to decrease discretionary spending, and reductions in our real estate footprint. Additionally, we elected to defer certain employer payroll taxes as allowable under the Coronavirus Aid, Relief, and Economic Security Act (the "CARES" Act) signed into law on March 27, 2020. Half of these deferrals are due in December 2021, and the remaining deferrals are due in December 2022.

Although we have implemented significant measures to mitigate further spread of the virus, our employees, customers, suppliers, and contractors may continue to experience disruptions to business activities due to potential

further government-mandated or voluntary shutdowns, general economic conditions, or other negative impacts of the COVID-19 pandemic. We are continuously monitoring the adverse effects of the pandemic and identifying steps to mitigate those effects. As the COVID-19 pandemic is continually evolving, we are uncertain of its ultimate duration and impact. See Part I, Item 1a. Risk Factors for further details regarding the potential impacts of COVID-19 to our results of operations, financial position, and cash flows.

Results of Operations

The following is a discussion of our results of operations in fiscal 2021 compared to fiscal 2020. A discussion of our fiscal 2020 results of operations compared to fiscal 2019 can be found within Part II, Item 7.Management's Discussion and Analysis within our fiscal 2020 Annual Report on Form 10-K filed with the Securities and Exchange Commission on October 23, 2020.

The following table sets forth information comparing the components of net income for the year ended August 31, 2021 with the year ended August 31, 2020 (in millions except per share data):

Net sales increased $134.7 million, or 4.0%, to $3.46 billion for the year ended August 31, 2021 compared with $3.33 billion reported for the year ended August 31, 2020. For the year ended August 31, 2021, we reported net income of $306.3 million compared with $248.3 million for the year ended August 31, 2020, an increase of $58.0 million, or 23.4%. For fiscal 2021, diluted earnings per share increased 33.7% to $8.38 from $6.27 for the prior-year period.

The following table reconciles certain U.S. generally accepted accounting principles (“U.S. GAAP”) financial measures to the corresponding non-U.S. GAAP measures referred to in the discussion of our results of operations, which exclude the impact of acquisition-related items, amortization of acquired intangible assets, share-based payment expense, special charges associated primarily with continued efforts to streamline the organization, and impairments of investments in unconsolidated affiliates. Although the impacts of these items have been recognized in prior periods and could recur in future periods, management typically excludes these items during internal reviews of performance and uses these non-U.S. GAAP measures for baseline comparative operational analysis, decision making, and other activities. These non-U.S. GAAP financial measures, including adjusted gross profit and margin, adjusted selling, distribution, and administrative (“SD&A”) expenses and adjusted SD&A expenses as a percent of net sales, adjusted operating profit and margin, adjusted other expense, adjusted net income, and adjusted diluted earnings per share, are provided to enhance the user’s overall understanding of our current financial performance. Specifically, we believe these non-U.S. GAAP measures provide greater comparability and

Net Sales

Net sales of $3.46 billion for the year ended August 31, 2021 increased by $134.7 million, or 4.0%, compared with the prior-year period. This increase was driven by improved sales performance in the second half of fiscal 2021. Sales in our ABL segment of $3.29 billion increased $106.4 million, or 3.3%, compared to the prior year. Within our ABL segment, sales through the independent sales network and direct sales network increased 5% and 9%, respectively, due primarily to these channels continuing to benefit from improved service levels and an improving economy. However, corporate accounts sales for fiscal 2021 were 12% lower year over year due to fewer nonessential renovations from large retailers in the first half of the fiscal year, and retail sales declined 17% due primarily to a customer inventory rebalancing in fiscal 2021. Sales within our ISG segment increased 21% to $190.0 million due primarily to strong demand for building and HVAC controls. Changes in foreign currency rates and revenues from acquired companies did not have a meaningful impact on net sales for fiscal 2021.

Gross Profit

Gross profit for fiscal 2021 increased $72.6 million, or 5.2%, to $1.48 billion compared with $1.40 billion for the prior year due. The increase in gross profit and margin was due primarily to increased sales as well as product and productivity improvements, partially offset by higher component and freight costs.

Operating Profit

SD&A expenses of $1.04 billion for the year ended August 31, 2021 increased $15.6 million, or 1.5%, compared with the prior year. The increase in SD&A expense was due primarily to higher outbound freight to support the increase in sales as well as increased employee-related costs, partially offset by lower travel expense and sales and marketing costs due to cost control and travel restrictions that have continued since the start of the COVID-19 pandemic. Additionally, share-based payment expense decreased in fiscal 2021 due to the discontinuation of certain retirement provisions in the equity incentive program that resulted in the acceleration of share-based payment expense for fiscal 2020 grants.

Compared with the prior-year period, SD&A expenses as a percent of net sales decreased 70 basis points to 30.2% for fiscal 2021 from 30.9% in fiscal 2020. Adjusted SD&A expenses were $968.7 million, or 28.0% of net sales, in fiscal 2021 compared to $947.3 million, or 28.5% of net sales, in the year-ago period.

During the year ended August 31, 2021, we recognized pre-tax special charges of $3.3 million compared with pre-tax special charges of $20.0 million recorded during the year ended August 31, 2020. Further details regarding our special charges are included in the Special Charges footnote of the Notes to Consolidated Financial Statements.

Operating profit for fiscal 2021 was $427.6 million compared with $353.9 million reported for the prior-year period, an increase of $73.7 million, or 20.8%. Operating profit margin increased 180 basis points to 12.4% for fiscal 2021 compared with 10.6% for fiscal 2020. The increase in operating profit margin reflects favorable gross profit margin, a decline in special charges, and our ability to leverage our operating costs.

Adjusted operating profit increased $50.0 million, or 11.0%, to $506.3 million compared with $456.3 million for fiscal 2020. Adjusted operating profit margin was 14.6% and 13.7% for fiscal 2021 and 2020, respectively.

Other Expense

Other expense consists of net interest expense and net miscellaneous expense, which includes non-service related components of net periodic pension cost, gains and losses associated with foreign currency-related transactions, and non-operating gains and losses.

Interest expense, net, was $23.2 million and $23.3 million for the years ended August 31, 2021 and 2020, respectively.

We reported net miscellaneous expense of $8.2 million in fiscal 2021 compared with $5.9 million in fiscal 2020. During fiscal 2021, we recorded impairment charges totaling $6.0 million for certain unconsolidated equity investments. Further details regarding the impairment charges are included in the Fair Value Measurements footnote of the Notes to Consolidated Financial Statements.

Income Taxes and Net Income

Our effective income tax rate was 22.7% and 23.5% for the years ended August 31, 2021 and 2020, respectively. The change in our effective income tax rate year over year is due primarily to the impacts of discrete items. Further details regarding income taxes are included in the Income Taxes footnote of the Notes to Consolidated Financial

24

Table of Contents

Statements. We estimate that our effective tax rate for fiscal 2022 will be approximately 23% before any discrete items, assuming the rates in our taxing jurisdictions remain generally consistent throughout the year.

Net income for fiscal 2021 increased $58.0 million, or 23.4%, to $306.3 million from $248.3 million reported for the prior year. The increase in net income resulted primarily from an increase in operating profit compared to the prior-year period partially offset by higher income tax expense related to the increase in profit. Adjusted net income for fiscal 2021 increased 13.6% to $371.7 million compared with $327.3 million in the year-ago period.

Diluted earnings per share for fiscal 2021 was $8.38 compared with $6.27 for the prior-year period, an increase of $2.11, or 33.7%. This increase reflects higher net income as well as lower outstanding diluted shares. Adjusted diluted earnings per share for fiscal 2021 was $10.17 compared with $8.27 for the prior-year period, an increase of $1.90, or 23.0%.

Segment Results

The following tables set forth information comparing the operating results of our segments, ABL and ISG, for the year ended August 31, 2021 with the year ended August 31, 2020 (in millions). We have recast historical information to conform to the current segment structure.

Add-back: Acquisition-related items (1) — 1.2

Adjusted operating profit margin 15.7 % 14.7 % 100 bps

_____________________________

(1) Acquisition-related items include profit in inventory.

ABL net sales for the year ended August 31, 2021 increased 3.3% compared with theprior-year period due primarily to improvements within the independent sales network and direct sales network channels as our go-to-market activities leveraged improvements in the construction market and wider economy. These gains were partially offset by lower sales in the retail channel due to a customer inventory rebalancing and in the corporate accounts channel due to fewer nonessential renovations from large retailers in the first half of the fiscal year. Operating profit for ABL was $476.2 million (14.5% of ABL net sales) for the year ended August 31, 2021 compared to $425.8 million (13.4% of ABL net sales) in the prior-year period, an increase of $50.4 million. The increase in operating profit was due primarily to higher sales as well as product and productivity improvements, partially offset by higher component, freight, and operating costs. The operating profit margin increase year over year reflects higher sales as well as our ability to successfully leverage our operating costs. Adjusted operating profit for ABL increased $47.3 million to $515.1 million for the year ended August 31, 2021 compared with the prior year period.

Year Ended August 31,

ISG 2021 2020 Increase (Decrease) Percent Change

Operating profit (loss) margin 5.2 % (2.5) % 770 bps

Adjusted operating profit margin 13.5 % 9.5 % 400 bps

ISG net sales for the year ended August 31, 2021 increased 21.0% compared with the prior-year period driven primarily by strong demand for building and HVAC controls. ISG operating profit was $9.9 million for the year ended

25

Table of Contents

August 31, 2021 compared with a $3.9 million operating loss in the prior-year period, an increase of $13.8 million. This increase was due primarily to higher sales, partially offset by increased employee costs. Adjusted operating profit for ISG increased $10.7 million to $25.6 million for the year ended August 31, 2021 compared with the prior-year period.

Outlook

We expect the challenging global supply chain environment to continue into fiscal 2022. We currently expect ABL to grow net sales in the high single digits for the full year of 2022 and ISG to deliver net sales growth in the mid-teens. Additionally, we expect a 42% plus annualized gross profit margin for the full year of 2022, and we believe that we can continue to leverage our operating costs as we increase net sales.

Accounting Standards Adopted in Fiscal 2021 and Accounting Standards Yet to Be Adopted

See the New Accounting Pronouncements footnote of the Notes to Consolidated Financial Statements for information on recently adopted and upcoming standards.

Critical Accounting Estimates

Management’s Discussion and Analysis of Financial Condition and Results of Operations addresses the financial condition and results of operations as reflected in our Consolidated Financial Statements, which have been prepared in accordance with U.S. GAAP. As discussed in the Description of Business and Basis of Presentation footnote of the Notes to Consolidated Financial Statements, the preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements as well as reported amounts of revenue and expense during the reporting period. On an ongoing basis, we evaluate our estimates and judgments. We base our estimates and judgments on our substantial historical experience and/or other relevant factors, such as projections of future performance, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results could differ from those estimates. We discuss the development of accounting estimates with our Audit Committee of the Board of Directors on a recurring basis. See the Significant Accounting Policies footnote of the Notes to Consolidated Financial Statements for a summary of our accounting policies.

We believe the following accounting topics represent our critical accounting estimates.

Revenue Recognition

We recognize revenue when we transfer control of goods and services to our customers. Revenue is measured as the amount of consideration we expect to receive in exchange for goods and services. In the period of revenue recognition, we estimate and record provisions for certain rebates, sales incentives, product returns, and discounts to customers, in most instances, as reductions of revenue. We also maintain one-time or on-going marketing and trade-promotion programs with certain customers that require us to estimate and accrue the expected costs of such programs. Generally, these items are estimated based on customer agreements, historical trends, and expected demand. For sales with multiple deliverables, significant judgment may be required to determine which performance obligations are distinct and should be accounted for separately. We allocate the expected consideration to be collected to each distinct performance obligation based on its standalone selling price. Standalone selling price is generally estimated using a cost plus margin valuation when no observable input is available.

Actual results could differ from estimates, which would require adjustments to recorded amounts. Please refer to the Revenue Recognition footnote of the Notes to Consolidated Financial Statements for additional information regarding estimates related to revenue recognition.

Inventories

Inventories include materials, direct labor, in-bound freight, customs, duties, tariffs, and related manufacturing overhead and are stated at the lower of cost (on a first-in, first-out or average-cost basis) and net realizable value. We review inventory quantities on hand and record a provision for excess or obsolete inventory primarily based on estimated future demand and current market conditions. A significant change in customer demand, market conditions, or technology could render certain inventory obsolete and thus could have a material adverse impact on our operating results in the period the change occurs.

Table of Contents

Goodwill and Indefinite-Lived Intangible Assets

Indefinite-lived intangible assets consist of trade names acquired through multiple acquisitions that are expected to generate cash flows indefinitely. Significant estimates and assumptions were used to both identify and determine the initial fair value of these acquired intangible assets, often with the assistance of third-party valuation specialists. These assumptions include, but are not limited to, estimated future net sales and profitability, customer attrition rates, royalty rates, and discount rates. Goodwill is calculated as the residual value of an acquisition's purchase price less the value of the identifiable net assets and is thus dependent on the appropriate identification and valuation of the net assets obtained in an acquisition.

We also review goodwill and indefinite-lived intangible assets for impairment on an annual basis in the fiscal fourth quarter or on an interim basis if an event occurs or circumstances change that would more likely than not indicate that the fair value of the goodwill or an indefinite-lived asset is below its carrying value. An impairment loss for goodwill or an indefinite-lived intangible asset would be recognized based on the difference between the carrying value of the asset and its estimated fair value, which would be determined based on either discounted future cash flows or another appropriate fair value method. The evaluation of goodwill and indefinite-lived intangibles for impairment requires management to use significant judgments and estimates in accordance with U.S. GAAP including, but not limited to, economic, industry, and Company-specific qualitative factors, projected future net sales, operating results, and cash flows.

Although we currently believe that the estimates used in the evaluation of goodwill and indefinite-lived intangibles are reasonable, differences between actual and expected net sales, operating results, and cash flows and/or changes in the discount rates or theoretical royalty rates used could cause these assets to be deemed impaired. If this occurs, we are required to record a non-cash charge to earnings for the write-down in the value of such assets. Such charges could have a material adverse effect on our results of operations and financial position but not our cash flows from operations.

Goodwill

We perform our goodwill impairment analysis at the reporting unit level using a combination of discounted future cash flows and relevant market multiples. Our discounted cash flow analyses required significant assumptions about discount rates, short and long-term growth rates, and future profitability. We utilized estimated discount rates ranging from 9.0% to 12.0% as of June 1, 2021, based on the Capital Asset Pricing Model, which considers the risk-free interest rate, beta, market risk premium, and size premium to determine an appropriate discount rate for a reporting unit. Short-term growth rates were based on management’s forecasted financial results, which consider key business drivers such as specific revenue growth initiatives, market share changes, growth in our addressable market, and general economic factors such as macroeconomic conditions, credit availability, and interest rates. Short-term growth rates used in the fiscal 2021 impairment analysis reflected additional estimation uncertainty as a result of the COVID-19 pandemic. We calculated the discounted cash flows attributable to our reporting units for a 10-year discrete period with a terminal value and compared this calculation to the discounted cash flows generated over a 40-year period to corroborate the reasonableness of assumptions used. The long-term growth rate used in determining terminal value was estimated at 3.5% and was primarily based on our understanding of projections for expected long-term growth in our addressable market and historical long-term performance.

We corroborate the values determined from our discounted cash flow models using a relevant market multiple, generally published earnings and/or revenue multiples. We also reconcile the sum of the fair values for each reporting unit to our market capitalization at the testing date, including consideration of a control premium.

Any reasonably likely change in the assumptions used in these analyses, including revenue growth rates, the discount rates, long-term growth rates, or relevant multiples would not cause the carrying value of any reporting unit to exceed its estimated fair value as determined under the goodwill impairment analysis. See the Significant Accounting Policies footnote of the Notes to Consolidated Financial Statements for further details.

Indefinite-Lived Intangible Assets

Our indefinite-lived intangible assets consist of 13 trade names with an aggregate carrying value of $174.8 million at August 31, 2021. We utilized significant assumptions to estimate the fair value of these indefinite-lived trade names using a fair value model based on discounted future cash flows (“fair value model”) in accordance with Accounting Standards Codification (“ASC”) Topic 820, Fair Value Measurement (“ASC 820”). Future cash flows associated with each of our indefinite-lived trade names are calculated by multiplying a theoretical royalty rate a willing third party would pay for use of the particular trade name by estimated future net sales attributable to the relevant trade name. The present values of the resulting after-tax cash flows is our current estimate of the fair value of each trade name.

27

Table of Contents

This fair value model requires us to make several significant assumptions, including specific estimated future net sales (including short and long-term growth rates), the royalty rate, and the discount rate for each trade name.

Future net sales and short-term growth rates are estimated for each particular trade name based on management’s financial forecasts, which consider key business drivers, such as specific revenue growth initiatives, market share changes, expected growth in our addressable market, and general economic factors, such as macroeconomic conditions, credit availability, and interest rates. Short-term growth rates used in the fiscal 2021 impairment analysis reflected additional estimation uncertainty as a result of the COVID-19 pandemic. The long-term growth rate used in determining terminal value was estimated at 3.5% and was based primarily on our understanding of projections for expected long-term growth for our addressable market and historical long-term performance. The theoretical royalty rate is estimated primarily using management’s assumptions regarding the amount a willing third party would pay to use the particular trade name and is compared with market information for similar intellectual property within and outside of the industry. If future operating results are unfavorable compared with forecasted amounts, we may be required to reduce the theoretical royalty rate used in the fair value model, which would result in lower expected future after-tax cash flows in the fair value model. We utilized a range of estimated discount rates between 9% and 12% as of June 1, 2021, based on the Capital Asset Pricing Model, which considers the current risk-free interest rate, beta, market risk premium, and size premium appropriate for each intangible.

During fiscal 2021, we performed an evaluation of the fair values of our indefinite-lived trade names . Our expected revenues were based on our fiscal 2022 projections and recent third-party lighting, controls, and building technology solutions market growth estimates for fiscal 2023 through 2025 as of June 1, 2021. We also included revenue growth estimates based on current initiatives expected to help improve performance. During fiscal 2021, estimated theoretical royalty rates ranged between 1% and 3%. The impairment analyses of our indefinite-lived intangible assets indicated that their fair values exceeded their carrying values; therefore, no impairments were recorded for fiscal 2021. Any reasonably likely change in the assumptions used in the analyses for our trade names, including revenue growth rates, royalty rates, and discount rates, would not be material to our financial condition or results of operations. See the Significant Accounting Policies footnote of the Notes to Consolidated Financial Statements for further details.

Share-based Payment Expense

We recognize compensation cost for share-based payment transactions in the financial statements under the provisions of ASC Topic 718, Compensation — Stock Compensation (“ASC 718”). Restricted stock awards, performance stock awards, and director stock units representing certain deferrals into the Director Deferred Compensation Plan are valued based on the fair value of our common stock on the grant date. We review the values of our performance awards on a frequent and recurring basis and adjust those values based on the probability that the related performance metric will be satisfied. We utilize the Black-Scholes model in deriving the fair value estimates of our stock option awards that only have a service requirement, and we utilize the Monte Carlo simulation model to determine grant date fair value estimates of stock options also subject to a market condition.

Additionally, we estimate forfeitures of all share-based awards at the time of grant, which are revised in subsequent periods if actual forfeitures differ from initial estimates. Forfeitures are estimated based on historical experience. If factors change causing different assumptions to be made in future periods, estimated compensation expense may differ significantly from that recorded in the current period.

We generally recognize compensation cost for share-based payment transactions on a straight-line basis over an award's requisite service period as defined by ASC 718. In certain circumstances, such as when a performance award is subject to graded vesting, we apply the accelerated attribution method to recognize compensation cost related to our share-based payment awards.

See the Share-based Payments footnote of the Notes to Consolidated Financial Statements for further information on these awards, including assumptions used in estimating the fair value of our awards.

Product Warranty and Recall Costs

Our products generally have a standard warranty term of five years. We accrue for the estimated amount of future warranty costs when the related revenue is recognized. Estimated future warranty costs are primarily based on historical experience of identified warranty claims. We are fully self-insured for product warranty costs. Historical warranty costs have been within expectations. Although we expect that historical activity will continue to be the best indicator of future warranty costs, there can be no assurance that future warranty costs will not exceed historical amounts. Estimated costs related to product recalls based on a formal campaign soliciting repair or return of that product are accrued when they are deemed to be probable and can be reasonably estimated. If actual future

28

Table of Contents

warranty or recall costs exceed recorded amounts, additional accruals may be required, which could have a material adverse impact on our results of operations and cash flow.

We also sell certain service-type warranties that extend coverages for products beyond their base warranties. We account for service-type warranties as distinct performance obligations, allocate an appropriate amount of transaction price to these transactions, and recognize revenue for these contracts ratably over the life of the additional warranty period. We allocate transaction price to our service-type warranties largely based on expectations of cost plus margin based on our estimate of future claims. These estimates are subject to a higher level of estimation uncertainty than other estimates, as we have less experience in costs in the extended warranty period. Claims related to service-type warranties are expensed as incurred.

Item 7a.Quantitative and Qualitative Disclosures about Market Risk

General

We are exposed to worldwide market risks that may impact our Consolidated Balance Sheets, Consolidated Statements of Comprehensive Income, Consolidated Statements of Cash Flows, and Consolidated Statements of Stockholders' Equity due primarily to changing interest and foreign exchange rates. We do not currently engage in significant commodity hedging transactions for raw materials. The following discussion provides additional information regarding our market risks.

Interest Rates

Interest rate fluctuations expose variable-rate debt of the organization to changes in interest expense and cash flows. Our long-term debt as of August 31, 2020 consisted primarily of variable-rate obligations, whereas as of August 31, 2021, our long-term debt consisted of fixed-rate senior unsecured notes. A fluctuation in interest rates would not affect interest expense or cash flows related to the Company’s fixed-rate debt. However, a 10% increase in market interest rates at August 31, 2021 would have decreased the estimated fair value of our senior unsecured notes by approximately $9.2 million. See the Debt and Lines of Credit footnote of the Notes to Consolidated Financial Statements contained in this Form 10-K for additional information.

Foreign Exchange Rates

The majority of our net sales, expense, and capital purchases are transacted in U.S. dollars. However, exposure with respect to foreign exchange rate fluctuation exists due to our operations in Mexico and Canada, where a significant portion of products sold are produced or sourced from the United States, and, to a lesser extent, in Europe. Based on fiscal 2021 performance, a hypothetical decline in the value of the Canadian dollar in relation to the U.S. dollar of 10% would negatively impact operating profit by approximately $13 million, while a hypothetical appreciation of 10% in the value of the Canadian dollar in relation to the U.S. dollar would favorably impact operating profit by approximately $16 million. In addition to products and services sold in Mexico, a significant portion of the goods sold in the United States are manufactured in Mexico. A hypothetical 10% decrease in the value of the Mexican peso in relation to the U.S. dollar would favorably impact operating profit by approximately $12 million, while a hypothetical increase of 10% in the value of the Mexican peso in relation to the U.S. dollar would negatively impact operating profits by approximately $14 million. The individual impacts to the operating profit of hypothetical currency fluctuations in the Canadian dollar and Mexican peso have been calculated in isolation from any potential responses to address such exchange rate changes in our foreign markets.

Our exposure to foreign currency risk related to our operations in Europe is immaterial and has been excluded from this analysis.

MANAGEMENT’S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

ACUITY BRANDS, INC.

The management of Acuity Brands, Inc. is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting is defined in Rule 13a-15(f) and 15d-15(f) promulgated under the Securities Exchange Act of 1934. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. 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.

The Company’s management assessed the effectiveness of the Company’s internal control over financial reporting as of August 31, 2021. In making this assessment, the Company’s management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”) in Internal Control-Integrated Framework (2013 Framework). Based on this assessment, management believes that, as of August 31, 2021, the Company’s internal control over financial reporting is effective.

Management’s assessment of and conclusion on the effectiveness of internal control over financial reporting did not include the internal controls of the acquired businesses of Rockpile Ventures and ams OSRAM’s North American Digital Systems, (collectively, the “2021 Acquisitions”), which are included in the Company’s consolidated financial statements as of August 31, 2021 and for the period from the respective acquisition dates through August 31, 2021. As of August 31, 2021, the 2021 Acquisitions constituted less than 4% of the Company’s consolidated assets and stockholders' equity. For the year ended August 31, 2021, the 2021 Acquisitions constituted less than 1% of both the Company's net sales and pre-tax income.

The Company’s independent registered public accounting firm has issued an audit report on their audit of the Company’s internal control over financial reporting. This report dated October 27, 2021 is included within this Form 10-K.

We have audited the accompanying consolidated balance sheets of Acuity Brands, Inc. (the Company) as of August 31, 2021 and 2020, the related consolidated statements of comprehensive income, cash flows and stockholders’ equity for each of the three years in the period ended August 31, 2021, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at August 31, 2021 and 2020, and the results of its operations and its cash flows for each of the three years in the period ended August 31, 2021, in conformity with U.S. generally accepted accounting principles.

We also have 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 August 31, 2021, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework), and our report dated October 27, 2021 expressed an unqualified opinion thereon.

Report of Independent Registered Public Accounting Firm

To the Stockholders and Board of Directors of Acuity Brands, Inc.

Opinion on Internal Control over Financial Reporting

We have audited Acuity Brands, Inc.’s internal control over financial reporting as of August 31, 2021, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, Acuity Brands, Inc. (the Company) maintained, in all material respects, effective internal control over financial reporting as of August 31, 2021, based on the COSO criteria.

As indicated in the accompanying Management’s Report on Internal Control Over Financial Reporting, management’s assessment of and conclusion on the effectiveness of internal control over financial reporting did not include the internal controls of the acquired businesses of Rockpile Ventures and ams Osram's North American Digital Systems (collectively, the 2021 Acquisitions), which are included in the 2021 consolidated financial statements of the Company and constituted less than 4% of total assets and stockholders' equity as of August 31, 2021 and less than 1% of net sales and pre-tax income for the year then ended. Our audit of internal control over financial reporting of the Company also did not include an evaluation of the internal control over financial reporting of the 2021 Acquisitions.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of August 31, 2021 and 2020, the related consolidated statements of comprehensive income, cash flows and stockholders’ equity for each of the three years in the period ended August 31, 2021, and the related notes and our report dated October 27, 2021 expressed an unqualified opinion thereon.
