(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 a valuable difference in people's lives. We achieve growth through the development of innovative new products and services, including lighting, lighting controls, building management systems, and location-aware applications. ABL Segment ABL's portfolio of lighting solutions includes commercial, architectural, and specialty lighting in addition to lighting controls and components that can be combined to create integrated lighting controls systems. We offer devices such as luminaires that predominantly utilize light emitting diode (“LED”) technology designed to optimize energy efficiency and comfort for various indoor and outdoor applications. ABL's portfolio of products includes but is not limited to the following brands: Lithonia Lighting®, Holophane®, Peerless®, Gotham®, Mark Architectural LightingTM, Winona® Lighting, Juno®, IndyTM, AculuxTM, Healthcare Lighting®, Hydrel®, American Electric Lighting®, Sunoptics®, eldoLED®, nLight®, Sensor Switch®, IOTA®, A-LightTM, CycloneTM, Eureka®, Lumniaire LEDTM, Luminis®, Dark to Light®, and RELOC® Wiring Solutions. Principal customers of ABL include electrical distributors, retail home improvement centers, electric utilities, national accounts, digital retailers, lighting showrooms, and energy service companies located in North America and select international markets serving new construction, renovation and retrofit, and maintenance and repair applications. 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, our sales forces utilize a variety of distribution methods to meet specific individual customer or country requirements. ABL comprised approximately 95% of consolidated revenues during the three and nine months ended May 31, 2022 and 2021. ISG Segment ISG delivers products and services that make spaces smarter, safer, and greener. ISG offers building management systems and location-aware applications. 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 capabilities 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® and AtriusTM. ISG comprised approximately 5% of consolidated revenues during the three and nine months ended May 31, 2022 and 2021. We have prepared the Consolidated Financial Statements in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) to present the financial position, results of operations, and cash flows of Acuity Brands, Inc. and its wholly-owned subsidiaries. These unaudited interim consolidated financial statements reflect all normal and recurring adjustments that are, in the opinion of management, necessary to present fairly our consolidated financial position as of May 31, 2022, our consolidated comprehensive income for the three and nine months ended May 31, 2022 and 2021, and our consolidated cash flows for the nine months ended May 31, 2022 and 2021. Certain information and footnote disclosures normally included in our annual financial statements prepared in accordance with U.S. GAAP have been condensed or omitted. However, we believe that the disclosures included herein are adequate to make the information presented not misleading. These financial statements should be read in conjunction with the audited consolidated financial statements as of and for the three years ended August 31, 2021 and notes thereto included in our Annual Report on Form 10-K filed with the Securities and Exchange Commission (the “SEC”) on October 27, 2021 (File No. 001-16583) (“Form 10-K”). The results of operations for the three and nine months ended May 31, 2022 are not necessarily indicative of the results to be expected for the full fiscal 2022 year due primarily to continued uncertainty of general economic conditions that may impact our key end markets for the remainder of fiscal 2022, seasonality, and the impact of any acquisitions, among other reasons. We are uncertain of the future impact of the ongoing COVID-19 pandemic or recovery of prior deterioration in economic conditions to our sales channels, supply chain, manufacturing, and distribution as well as overall construction, renovation, and consumer spending. Additionally, the current conflict between Russia and Ukraine and the related sanctions and other penalties imposed by countries across the globe against Russia are creating substantial uncertainty in the global economy. While we do not have operations in Russia or Ukraine and do not have significant direct exposure to customers and vendors in those countries, we are unable to predict the impact that these actions will have on the global economy or on our financial condition, results of operations, and cash flows as of the date of these financial statements.
