Chairman’s Letter

TO  OU R  STA KEHOLDERS

In  2010,  Acuity  Brands  performed  well  given  the  considerable 

challenges  of  a  weak  economic  environment,  particularly  as  it 

impacted U.S. non-residential construction, a key market for us 

which  declined  approximately  15%  during  the  fiscal  year.  This 

dramatic  level  of  market  decline  would  have  devastated  the 

financial performance of most companies, and yet our revenues 

in  2010  were  off  less  than  2%  while  our  profitability  remained 

stable.  To  me,  the  difference  was  the  dedication  and  focus  of 

our  6,000  associates.  Every  day  they  provided  our  customers 

with  great  value,  supported  each  other  to  improve  and  win  in 

the marketplace, and endeavored to create long-term value for 

our  stockholders.  While  we  expect  to  deliver  year-over-year 

improvement—and  anything  less  is  disappointing—we  were 

pleased with our success in 2010.

2010 FINANCIAL HIGHLIGHTS

Adjusting for special charges and refinancing activity, we delivered:

• Net sales of $1.63 billion, down 2 percent;

• A gross profit margin of 40.7%, up 240 basis points;

• An adjusted operating profit margin of 10.2%, down 70 basis points;

• Adjusted diluted earnings per share from continuing operations of $2.08, down 14%;

• Cash flow from operations of $161 million, up 73%; and

• Return on stockholders’ equity of 11.4%.

Acuity Brands, Inc.  3

This  level  of  performance  was  even  more  remarkable  considering  the  significant 

investments  we  made,  particularly  in  the  second  half  of  the  year.  These  investments 

were in technology and innovation, new product introductions, including light-emitting 

diode (“LED”) and organic LED (“OLED”)-based luminaires and control devices, and 

expansion in certain geographies and existing channels. While these investments neg-

atively affected our short-term performance, they are in the very areas where we see 

great  growth  potential  over  the  next  decade.  Because  of  the  focus  our  team  has  on 

delivering  value  for  our  customers  and  driving  productivity,  we  were  able  to  protect 

our operating margins while delivering $161 million in cash from operating activities. 

We  also  strengthened  our  liquidity  and  financial  flexibility  through  our  refinancing 

activities that increased our available cash and extended our debt maturities. All of this 

was  achieved  while  delivering  a  return  for  our  shareholders  in  excess  of  our  cost  of 

capital. Clearly a job well-done.

2010 ACHIEVEMENTS 

Our financial success in 2010 tells only part of our positive story. On the strategic front, 

we made great strides to better position the company for future growth. For the second 

year in a row, we added more than 100 new products to our industry-leading portfolio, 

many incorporating the latest in advanced lighting technologies, including the intro-

duction of our first OLED luminaire, a significant achievement. We invested heavily in 

new lighting and control technology, including the acquisition of Renaissance Lighting, 

which added to our growing portfolio of intellectual property. We made great strides in 

enhancing our supply chain, driving improvements in quality, delivery, cost and inno-

vation through the use of our time-tested lean business tools. Lastly, we expanded our 

access in certain channels, geographies and markets, including renovation and lighting 

controls. We believe these investments, which offer us tremendous growth opportunities 

over the next decade, have meaningfully increased the size of the addressable market 

for Acuity Brands, making us less reliant on the new construction cycle. We made these 

investments today because of the significant upside potential for growth tomorrow.

STRATEGIC FOCUS

The  lighting  industry  is  on  the  dawn  of  a  new  era  driven  by  significant  and  ever 

increasing pace of change in technology, particularly as lighting sources go electronic 

and incorporate new intelligent capabilities and features. This will drive more change 

in the lighting industry over the next decade than the industry has experienced in the 

previous century. Excitingly, Acuity Brands is poised to lead the industry into the age 

of intelligent lighting. As I noted above, we have invested  heavily  in  technology and 

innovation, particularly in solid-state lighting capabilities, lighting controls and prod-

uct portfolio expansion, while enhancing our access to more customers and markets. 

These investments are now bedrock on which we plan to grow our company. As I said 

in 2009, the next chapter in our evolution will be centered on internal growth fueled by 

a  customer-centric  focus  based  on  operational  excellence,  augmented  by  a  focused 

acquisition strategy. Our successes in 2010 show we are delivering on this vision. We 

have  the  skill  and  resources  to  build  on  our  leadership  position,  particularly  as  new 

technologies bring new opportunities.

“

The lighting industry is on the dawn of a new era driven by significant and 
ever increasing pace of change in technology, particularly as lighting sources 
go electronic and incorporate new intelligent capabilities and features.

”

Acuity  Brands  led  the  transformation  to  fluorescent  technology  and,  today,  we  have 

invested  heavily  to  lead  the  next  evolution  to  intelligent  lighting.  Intelligent  lighting 

solutions,  with  a  foundation  based  on  solid-state  components,  will  offer  customers 

unique features and benefits, particularly on controlling light while minimizing energy 

consumption and maintenance cost. Acuity Brands is a lighting company made up of 

lighting experts dedicated to providing customers with products and systems that cre-

ate superior lighting solutions for virtually any application. Because we are agnostic to 

the light source, our customers rely on us to offer the very best solutions for their needs 

without  a  bias  for  one  technology  over  another…just  the  best  solution.  This  unique 

position  affords  us  a  great  opportunity  to  develop  lighting  solutions  across  a  wide 

spectrum of technologies, offering customers the right solution for their specific needs. 

Our  investments  over  the  last  24  months  in  lighting  controls,  including  the  acquisi-

tions  of  LC&D,  Sensor  Switch  and  Renaissance  Lighting,  coupled  with  one  of  the 

largest luminaire portfolios in the industry, have created a very strong platform for us 

4  Acuity Brands, Inc.

Acuity Brands, Inc.  5

to  offer  lighting  solutions,  not  just  devices,  that  deliver  on  the  promise  of  a  superior 

lighting environment. We believe customers are likely to pay more for a complete light-

ing solution, compared with individual devices, as they will be easier to install and can be 

managed in a way to optimize both the lighting environment and energy consumption. 

As electronics enter the lighting arena, bringing with it the age of intelligent lighting 

solutions,  Acuity  Brands  is  positioned  to  drive  this  evolution  where  superior  lighting 

performance will be the norm and energy savings will pay for the investment. Although 

2011 is expected to be another challenging year due to weak general economic condi-

tions, as we look out over the next handful of years it is entirely possible the address-

able market size for Acuity Brands could be $16 billion or more annually, up from $9.3 

billion in 2010…this is an increase of more than 70%. This is why we say, “Our future 

is Bright.”

CLOSING COMMENTS

John L. Clendenin recently announced his retirement from the Board of Directors of 

Acuity Brands. John has been a valued director since the inception of the company in 

2001.  I  thank  John  for  his  vision,  wisdom  and  courage  to  help  guide  the  company 

through a period of extraordinary transformation. We will miss his keen intellect, his 

exceptional strategic vision, and his unwavering commitment to our company. 

On  behalf  of  the  Board  of  Directors,  I  want  to  thank  our  6,000  associates  for  their 

continued contributions and dedication to our vision, our customers for their business, 

our  suppliers  for  their  support,  and  our  stockholders  for  the  partnership  we  share  in 

our enterprise.

Sincerely,

Vernon J. Nagel

Item 1. Business
($ in millions, except per-share data and as indicated)

Overview

Acuity Brands, Inc. (“Acuity Brands”), the parent company of Acuity Brands Lighting, Inc. (“ABL”), and
other subsidiaries (collectively referred to herein as “the Company”), was incorporated in 2001 under the laws of the
State of Delaware. The Company is one of the world’s leading providers of lighting fixtures, control devices,
components, systems and services for commercial and institutional, industrial, infrastructure, and residential
applications for various markets throughout North America and select international markets.

The Company designs, produces, and distributes a full range of indoor and outdoor lighting and control
systems for commercial and institutional, industrial, infrastructure, and residential applications. The Company
manufactures or procures lighting products primarily in North America, Europe, and Asia. These products and
related services are marketed under numerous brand names, including Lithonia Lighting», Holophane», Peerless»,
Mark Architectural LightingTM, Hydrel», American Electric Lighting», Gotham», Carandini», Metal Optics»,
Antique Street LampsTM, TersenTM, Synergy» Lighting Controls, Sensor Switch», Lighting Control & DesignTM, and
ROAM». As of August 31, 2010, the Company manufactures products in 14 plants in North America and two plants
in Europe.

Principal customers include electrical distributors, retail home improvement centers, national accounts,
electric utilities, municipalities, and lighting showrooms located in North America and select international markets
serving new construction, renovation, and facility maintenance applications. In North America, the Company’s
products and lighting systems are sold by independent sales agents and factory sales representatives who cover
specific geographic areas and market segments. Products are delivered directly or through a network of distribution
centers, regional warehouses, and commercial warehouses using both common carriers and a company-owned truck
fleet. To serve international customers, the Company employs a sales force that utilizes distribution methods to
meet specific individual customer or country requirements. In fiscal 2010, North American sales accounted for
approximately 97% of net sales. See the Geographic Information footnote of the Notes to Consolidated Financial

Specialty Products Business Spin-off

Acuity Brands completed the spin-off of its specialty products business (the “Spin-off”), Zep Inc. (“Zep”), on
October 31, 2007, by distributing all of the shares of Zep common stock, par value $.01 per share, to the Company’s
stockholders of record as of October 17, 2007. The Company’s stockholders received one Zep share, together with
an associated preferred stock purchase right, for every two shares of the Company’s common stock they owned.
Stockholders received cash in lieu of fractional shares for amounts less than one full Zep share.

As a result of the Spin-off, the Company’s financial statements have been prepared with the net assets, results
of operations, and cash flows of the specialty products business presented as discontinued operations. All historical
statements have been restated to conform to this presentation. Refer to the Discontinued Operations footnote of the
Notes to Consolidated Financial Statements.

Industry Overview

Based on industry sources and government information, the Company estimates that in fiscal 2010 the size of
the North American market for lighting fixtures, lighting controls, and related product and services that is served by
the Company was approximately $9.3 billion. This includes non-portable light fixtures (as defined by the National
Electrical Manufacturers Association), poles for outdoor lighting products, emergency lighting fixtures, and energy
management and architectural lighting control systems. This market estimate is based on a combination of external
industry data and internal estimates, and excludes portable and vehicular lighting fixtures and related lighting

3

components, such as lighting ballasts and lamps. The U.S. market, which represents approximately 82% of the
North American market, is relatively fragmented. The Company estimates that the top four manufacturers
(including Acuity Brands Lighting) participate in varying degrees in the total North American lighting fixture
and controls market and have approximately half of the total market share. The remainder of the North American
market is served by hundreds of other lighting manufacturers, including privately-owned and primarily smaller
companies.

The Company operates in a highly competitive industry that is affected by volatility in a number of general
business and economic factors, such as gross domestic product growth, employment levels, credit availability and
commodity costs. The Company’s primary market, non-residential construction, is sensitive to the volatility of these
general economic factors. Based on industry sources, the Company estimates that new construction and additions in
fiscal 2010 and 2009 accounted for approximately 74% and 78%, respectively, of the non-residential market while
alterations, including renovation, accounted for approximately 26% and 22%, respectively. This mix can vary over
time depending on economic conditions. As such, given the current economic environment, new construction in the
non-residential market declined at a more rapid rate than alterations, which caused the change in mix. Construction
spending on infrastructure projects such as highways, streets, and urban developments also has a material impact on
the demand for the Company’s infrastructure-focused products. Demand for the Company’s lighting products sold
through its retail channels are highly dependent on economic drivers, such as consumer spending and discretionary
income, along with housing construction and home improvement spending.

A growing source of demand for the lighting industry is being attributed to the renovation and replacement of
lighting systems in existing buildings. The potential U.S. market size is estimated to be significant (possibly greater
than $100 billion of installed base) due to square footage of existing non-residential buildings containing older, less
efficient lighting systems.

The industry is influenced by the development of new lighting technologies, including light emitting diode
(“LED”), electronic ballasts, embedded controls, and more effective optical designs; federal and state requirements
for updated energy codes; incentives by federal, state, and local municipal authorities, as well as utility companies
for using more energy-efficient fixtures and controls; and design technologies addressing sustainability. Traditional
lighting manufacturers, including the Company, are offering product solutions based on these technologies utilizing
internally developed, licensed, or acquired intellectual property. In addition, traditional lighting manufacturers are
experiencing competition from new entrants with a focus on new technology-based lighting solutions.

Consolidation remains a key trend in the lighting equipment and controls industry, as well as the broader
electrical industry leading to more extensive product offerings and increased globalization. Evidence of this trend
are the recent combinations among electrical distributors, the 2008 acquisition by Koninklijke Philips Electronics
N.V. of The Gentlyte Group Incorporated, and the Company’s fiscal 2009 acquisitions of Sensor Switch, Inc. and
Lighting Control & Design, Inc. and fiscal 2010 acquisition of Renaissance Lighting, Inc.

for indoor applications in the commercial, industrial, institutional, and infrastructure markets.

Sales of products accounted for approximately 99% of total consolidated net sales for Acuity Brands in fiscal

2010, 2009, and 2008.

Sales and Marketing

Sales. The Company sells to customers in the North American market with separate sales forces targeted at
delivering value added products and services to specific customer, channel, and geographic segments. As of
August 31, 2010, these sales forces consist of approximately 300 company-employed salespeople and a network of
approximately 200 independent sales agencies, each of which employs numerous salespeople. The Company also
operates two separate European sales forces and an international sales group coordinating export sales outside of
North America and Europe.

Marketing. The Company markets its products to end users in multiple channels through a broad spectrum of
marketing and promotional vehicles, including direct customer contact, trade shows, on-site training, print
advertising in industry publications, product brochures, and other literature, as well as the Internet and other
electronic media. The Company owns and operates training and display facilities in numerous locations throughout
North America and Europe designed to enhance the lighting knowledge of customers and industry professionals.

Customers

Customers of the Company include electrical distributors, retail home improvement centers, national accounts,
electric utilities, utility distributors, municipalities, contractors, lighting showrooms, and energy service companies.
In addition, there are a variety of other professionals, which for any given project could represent a significant
influence in the product specification process. These generally include contractors, engineers, architects, and
lighting designers.

A single customer of the Company, The Home Depot, accounted for approximately 11% of net sales of the
Company in fiscal 2010, 2009, and 2008. The loss of The Home Depot’s business could temporarily adversely affect
the Company’s results of operations.

Manufacturing

The Company operates 16 manufacturing facilities, including eight facilities in the United States, six facilities
in Mexico, and two facilities in Europe. The Company utilizes a blend of internal and outsourced manufacturing
processes and capabilities to fulfill a variety of customer needs in the most cost-effective manner. Critical processes,
including assembly, reflector forming and anodizing and high-end glass production, are primarily performed at
company-owned facilities, offering the ability to differentiate end-products through superior capabilities. Other
critical components, such as lamps, LEDs, sockets, ballasts, and power supplies are purchased primarily from
outside vendors. Investment is focused on improving capabilities, product quality, and manufacturing efficiency.
Outsourcing production and distribution to local suppliers’ factories and warehouses also provides an opportunity to
lower Company-owned component inventory while maintaining high service levels through frequent just-in-time
deliveries. The Company also utilizes contract manufacturing from U.S., Asian, and European sources for certain
products and purchases certain finished goods, including poles, to complement its area lighting fixtures and a

5

variety of residential and commercial lighting equipment. In fiscal 2010, net sales of finished product manufactured
by others accounted for approximately 22% of the Company’s net sales, while the Company’s U.S. operations
produced approximately 25%; Mexico produced approximately 50%; and Europe produced approximately 3%.

Management continues to focus on certain initiatives to make the Company more globally competitive. One of
these initiatives relates to enhancing the Company’s global supply chain and includes the consolidation of certain
manufacturing facilities into more efficient locations. Since the beginning of fiscal 2002, the Company has closed
15 manufacturing facilities, including two separate facilities downsized in fiscal 2010 and 2009. These consol-
idation efforts reduced the total square footage used for manufacturing by approximately 39%.

Distribution

Products are delivered directly or through a network of strategically located distribution centers, regional
warehouses, and commercial warehouses in North America using both common carriers and a company-owned
truck fleet. For international customers, distribution methods are adapted to meet individual customer or country
requirements.

Research and Development

Research and development (“R&D”) efforts are targeted toward the development of products with an ever-
increasing performance-to-cost ratio and energy efficiency, while close relationships with lamp, ballast, LED, and
power supply manufacturers are maintained to understand technology enhancements and incorporate them in the
Company’s fixture designs. For fiscal 2010, 2009, and 2008, research and development expense totaled $28.0,
$20.8, and $30.3, respectively. The increase in fiscal 2010 expense was due primarily to higher incentive
compensation associated with R&D associates compared with fiscal 2009 amounts.

Competition

The lighting equipment and controls market served by the Company is highly competitive, with some of the
largest suppliers serving many of the same markets and competing for the same customers. Competition is based on
numerous factors, including brand name recognition, price, product quality, product and lighting system design,
energy efficiency, customer relationships, and service capabilities. The Company’s primary competitors in the
North American lighting fixture and controls market include Cooper Industries plc., Hubbell Incorporated, and
Koninklijke Philips Electronics N.V. The Company estimates that the four largest manufacturers (including Acuity
Brands Lighting), which participate in varying degrees in the total North American lighting fixture and controls
market, have approximately half of the total market share. In addition to these primary competitors, the Company
also competes with hundreds of smaller lighting manufacturers, numerous lighting controls manufacturers of
varying size, and, to a lesser degree, large, diversified global electronics companies.

The market is competitive for lighting and lighting-related products and services and continues to evolve.
Consolidation remains a key trend. Certain broader and more global electrical manufacturers may be able to obtain
a competitive advantage over the Company by offering broader and more integrated electrical solutions utilizing
electrical, lighting, and building automation products. In addition, there have been a growing number of new
competitors offering solid-state (primarily LED) product solutions to compete with traditional lighting solutions.

Environmental Regulation

The operations of the Company are subject to numerous comprehensive laws and regulations relating to the
generation, storage, handling, transportation, and disposal of hazardous substances, as well as solid and hazardous
wastes, and to the remediation of contaminated sites. In addition, permits and environmental controls are required
for certain of the Company’s operations to limit air and water pollution, and these permits are subject to
modification, renewal, and revocation by issuing authorities. On an ongoing basis, the Company allocates
considerable resources, including investments in capital and operating costs relating to environmental compliance.
Environmental laws and regulations have generally become stricter in recent years, and state and federal
governments domestically and internationally are considering new laws and regulations governing raw material
composition, air emissions, and energy-efficiency. The Company is not aware of any pending legislation or

6

proposed regulation related to environmental issues that would have a material adverse effect on the Company. The
cost of responding to future changes, however, may be substantial. See Item 3: Legal Proceedings for further
discussion of environmental matters.

Raw Materials

The products produced by the Company require certain raw materials, including certain grades of steel and
aluminum, electrical components, plastics, and other petroleum-based materials and components. In fiscal 2010,
the Company purchased approximately 119,000 tons of steel and aluminum. The Company estimates that less than
10% of purchased raw materials are petroleum-based. Additionally, the Company estimates that approximately
3.5 million gallons of diesel fuel was consumed in fiscal 2010 through the Company’s distribution activities. The
Company purchases most raw materials on the open market and relies on third parties for providing certain finished
goods. Accordingly, the cost of products sold may be affected by changes in the market price of raw materials or the
sourcing of finished goods.

The Company does not currently engage in or expect to engage in significant commodity hedging transactions
for raw materials, though the Company has and will continue to commit to purchase certain materials for a period of
up to 12 months. Significant increases in the prices of the Company’s products due to increases in the cost of raw
materials could have a negative effect on demand for products and on profitability. While the Company has
generally been able to pass along these increases in cost in the form of higher selling prices for its products, there
can be no assurance that future disruptions in either supply or price of these materials will not negatively affect
future results. Decreases in the costs of raw materials generally are also passed along in the form of lower selling
prices.

The Company constantly monitors and investigates alternative suppliers and materials based on numerous
attributes including quality, service, and price. The Company’s ongoing efforts to improve the cost effectiveness of
its products and services may result in a reduction in the number of its suppliers. A reduction in the number of
suppliers could cause increased risk associated with reliance on a limited number of suppliers for certain raw
materials, component parts (such as lamps, LEDs, ballasts, and power supplies), and finished goods.

Backlog Orders

The Company produces and stocks quantities of inventory at key distribution centers and warehouses
throughout North America. The Company ships approximately 55% of sales orders during the month in which
those orders are placed. Sales order backlogs, believed to be firm as of August 31, 2010 and 2009, were $137.6 and
$137.0, respectively.

Patents, Licenses and Trademarks

The Company owns or has licenses to use various domestic and foreign patents and trademarks related to its
products, processes, and businesses. These intellectual property rights are important factors for its businesses. To
protect these proprietary rights, the Company relies on copyright, patent, trade secret, and trademark laws. Despite
these protections, unauthorized parties may attempt to infringe on the intellectual property of the Company.
Management is not aware of any pending claims asserting that the Company does not have the right to use intellectual
property that is material to the Company. While patents and patent applications in the aggregate are important to the
competitive position of the Company, no single patent or patent application is individually material to the Company.

Seasonality and Cyclicality

The Company’s business exhibits some seasonality, with net sales being affected by the impact of 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, the Company has experienced, and
generally expects to experience, its highest sales in the last two quarters of each fiscal year.

A significant portion of net sales relates to customers in the new construction and renovation markets. The new
construction market is cyclical in nature and subject to changes in general economic conditions. Unit sales volume

7

has a major impact on the profitability of the Company. Economic downturns and the potential decline in key
construction markets may have a material adverse effect on the net sales and operating income of the Company.

International Operations

The Company manufactures and assembles products at numerous facilities, some of which are located outside
the United States. Approximately 53% of the products sold by the Company are manufactured by the Company
outside the United States.

Of the Company’s total products sold, approximately 50% are produced at six facilities in Mexico. Most of
these facilities are authorized to operate as Maquiladoras by the Ministry of Economy of Mexico. Maquiladora
status allows the Company to import certain items from the United States into Mexico duty-free, provided that such
items, after processing, are re-exported from Mexico within 18 months. Maquiladora status, which is renewed every
year, is subject to various restrictions and requirements, including compliance with the terms of the Maquiladora
program and other local regulations. The Company may be required to make additional investments in automated
equipment to partially offset potential increases in labor and wage costs.

The Company’s initiatives to become more globally competitive include streamlining its global supply chain
by reducing the number of manufacturing facilities and enhancing the Company’s worldwide procurement and
sourcing capabilities. Management believes these initiatives will result in increased worldwide procurement and
sourcing of certain raw materials, component parts, and finished goods. As a consequence, economic, political,
military, social, or other events in a country where the Company manufactures, procures, or sources a significant
amount of raw materials, component parts, or finished goods, could interfere with the Company’s operations and
negatively impact the Company’s business.

For fiscal 2010, net sales outside the U.S. represented approximately 11% of total net sales. See the
Geographic 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.

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 Acuity Brands’ actual results to differ
materially from the anticipated results or other expectations expressed in the Company’s forward-looking state-
ments. See “Cautionary Statement Regarding Forward-Looking Statements” on page 36. These risks include,
without limitation:

Risks Related to the Business of Acuity Brands, Inc.

General business and economic conditions may affect demand for the Company’s products and services,
which could impact results from operations.

The Company competes based on such factors as name recognition and reputation, service, product features,
innovation, and price. In addition, the Company operates in a highly competitive environment that is influenced by a
number of general business and economic factors, such as general economic vitality, employment levels, credit
availability, interest rates and commodity costs. Declines in general economic activity may negatively impact new
construction, and renovation projects, which in turn may impact demand for the Company’s product and service
offerings. The impact of these factors could adversely affect the Company’s financial position, results from
operations, and cash flows.

Tight credit conditions could impair the ability of the Company and other industry parties to effectively
access capital markets, which could negatively impact the Company’s capital position and demand for the
Company’s products and services.

Tight credit conditions could impair the Company’s ability to effectively access capital. This could impair the
Company’s ability to refinance debt as it becomes due or to obtain additional credit, if needed. The inability to
effectively access capital markets could adversely affect the Company’s financial position, results from operations,
and cash flows.

In addition, the impact of the tight credit conditions has and could continue to impair the ability of real estate
developers, property owners, and contractors to effectively access capital markets or obtain reasonable costs of
capital on borrowed funds, resulting in a decline in construction and renovation projects. The inability of these
constituents to borrow money to fund construction and renovation projects reduces the demand for the Company’s
products and services and could adversely affect the Company’s results from operations and cash flow. The lack of
credit availability and the general economic conditions over the last two years have negatively impacted the
Company’s results from operations by reducing customer demand.

Acuity Brands is heavily dependent on the strength of construction activity.

Sales of lighting equipment depend significantly on the level of activity in new construction and renovations.
Demand for non-residential construction and renovation is driven by many factors, including but not limited to
economic activity, employment levels, credit availability, interest rates, accessibility to financing, and trends in
vacancy rates and rent values. Demand for new residential construction and remodeling is also affected by interest
rates and credit availability, as well as the supply of existing homes, price appreciation, and household formation
rates. Significant declines in either non-residential or residential construction activity could significantly impact the
Company’s results from operations and cash flow. Since early fiscal 2009, both the Company and the industry

9

experienced declines in sales volumes resulting from weakness in both the non-residential and residential
construction markets due to the weak economic environment.

Acuity Brands’ results may be adversely affected by fluctuations in the cost or availability of raw materi-
als, components, and purchased finished goods.

The Company utilizes a variety of raw materials and components in its production process including steel,
aluminum, lamps, LEDs, ballasts, power supplies, petroleum-based by-products, natural gas, and copper. Future
increases in the costs of these items could adversely affect operating margins, as there can be no assurance that
future raw material and component price increases will be successfully passed through to customers. The Company
generally sources these goods from a number of suppliers and, therefore, is reasonably insulated from risks affecting
any one supplier. However, there are a limited number of suppliers for certain components and certain purchased
finished goods, and disruptions in supply for those items could negatively impact the Company’s short-term
performance. Profitability and volume could be negatively impacted by limitations inherent within the supply chain
of certain of these component parts, including competitive, governmental, legal, natural disasters, and other events
that could impact both supply and price. Since mid-fiscal 2010, the industry has experienced shortages in certain
electronic components used in the manufacturing of ballasts and power supplies, resulting in delays in sourcing
these vital components. A persistent lack of availability of these components could adversely impact shipments in
future periods. Variability in cost and availability could adversely affect the Company’s results from operations and
cash flows.

Acuity Brand’s results may be adversely affected by the Company’s inability to maintain pricing.

Aggressive pricing actions by competitors may affect the Company’s ability to achieve desired unit volume
growth and profitability levels under its current pricing strategies. The Company may also decide to lower pricing to
match the competition. Additionally, the Company may not be able to increase prices to cover rising costs of
components and raw materials. Even if the Company were able to increase prices to cover costs, competitive pricing
pressures may not allow the Company to pass on any more than the cost increases which could negatively impact
gross margin percentages. Alternatively, if component and raw material costs were to decline, the marketplace may
not allow the Company to hold prices at their current levels, which could negatively impact both net sales and gross
margins.

Acuity Brands may experience difficulties in the consolidation of manufacturing facilities which could
impact the shipments to customers, product quality, and the ability to realize the expected savings from
streamlining actions.

During fiscal 2009, the Company continued its ongoing programs to streamline operations, including the
consolidation of certain manufacturing facilities and the reduction of overhead costs. Upon completion of these
actions, the Company realized annualized benefits of more than $50.0. During fiscal 2010, the Company announced
plans to relocate certain production and down-size two facilities, and, upon completion, the Company expects to
realize $10.0 in annualized benefits. The Company will gain from such activity only to the extent that it can
effectively leverage assets, personnel, and operating processes in the transition of production between manufac-
turing 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.

Acuity Brands is subject to risks related to operations outside the United States.

The Company has substantial activities outside of the United States, including sourcing of products, materials,
and components. The Company’s 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, particularly Mexico.
In addition to the risks that are common to both the Company’s domestic and international operations, the Company
faces risks specifically related to its foreign operations, including but not limited to: foreign currency fluctuations;
unstable political, social, regulatory, economic, financial, and market conditions; potential for privatization and
other confiscatory actions; trade restrictions and disruption; criminal activities; and unforeseen increases in tariffs
and taxes. The Company continues to monitor conditions affecting its international locations. Some of these risks

10

could have a material adverse effect on the Company’s business, financial condition, results from operations, and
cash flows in the future.

The Company is exposed to risks associated with fluctuations in foreign currency exchange rates against the
U.S. dollar resulting from non-U.S. dollar denominated transactions, particularly in our international operations.
Potential decreases in income could result from a strengthening or weakening in foreign exchange rates in relation
to the U.S. dollar.

Acuity Brands is subject to a broad range of environmental, health, and safety laws and regulations in
the jurisdictions in which it operates, and the Company may be exposed to substantial environmental,
health, and safety costs and liabilities.

The Company is subject to a broad range of environmental, health, and safety laws and regulations in the
jurisdictions in which the Company operates. These laws and regulations impose increasingly stringent environ-
mental, health, and safety protection standards and permitting requirements regarding, among other things, air
emissions, wastewater storage, treatment, and discharges, the use and handling of hazardous or toxic materials,
waste disposal practices, and the remediation of environmental contamination and working conditions for the
Company’s employees. 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. The Company may also be affected by future laws or regulations, including those imposed in response
to energy, climate change, or similar concerns. These laws may impact the manufacture and distribution of the
Company’s products and place restrictions on the products the Company can sell in certain geographical locations.

The costs of complying with these laws and regulations,

including participation in assessments and
remediation of contaminated sites and installation of pollution control facilities, have been, and in the future
could be, significant. In addition, these laws and regulations may also result in substantial environmental liabilities
associated with divested assets, third party locations, and past activities. The Company has established reserves for
environmental remediation activities and liabilities where appropriate. However, the cost of addressing environ-
mental matters (including the timing of any charges related thereto) cannot be predicted with certainty, and these
reserves may not ultimately be adequate, especially in light of potential changes in environmental conditions,
changing interpretations of laws and regulations by regulators and courts, the discovery of previously unknown
environmental conditions, the risk of governmental orders to carry out additional compliance on certain sites not
initially included in remediation in progress, the Company’s potential liability to remediate sites for which
provisions have not previously been established, and the adoption of more stringent environmental laws. Such
future developments could result in increased environmental costs and liabilities and could require significant
capital and other ongoing expenditures, any of which could have a material adverse effect on the Company’s
financial condition or results. In addition, the presence of environmental contamination at the Company’s properties
could adversely affect its ability to sell a property, receive full value for a property, or use a property as collateral for
a loan.

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

The Company is subject to various claims, including legal claims arising in the normal course of business. The
Company is insured up to specified limits for certain types of claims with a self-insurance retention of $0.5 per
occurrence, including product liability claims, and is fully self-insured for certain other types of claims, including
environmental, product recall, commercial disputes, and patent infringement. The Company establishes reserves 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 held
by the Company and/or the amounts reserved for such claims. In the event of unexpected future developments, it is
possible that the ultimate resolutions of such matters, if unfavorable, could have a material adverse effect on the
Company’s results from operations, financial position, or cash flows. The Company’s 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.

11

Acuity Brands may pursue future growth through strategic acquisitions and alliances, which may not
yield anticipated benefits.

The Company has and may continue to seek to improve its business through strategic acquisitions and
alliances. The Company will gain from such activity only to the extent that it can effectively leverage the assets,
including personnel, technology and operating processes, of the acquired businesses and alliances. Uncertainty is
inherent within the acquisition and alliance process, and unforeseen circumstances arising from recent and future
acquisitions or alliances could offset their anticipated benefits. In addition, unanticipated events, negative revisions
to valuation assumptions and estimates, and/or difficulties in attaining synergies, among other factors, could
adversely affect the Company’s ability to recover initial and subsequent investments, particularly those related to
acquired goodwill and intangible assets. Any of these factors could adversely affect the Company’s financial
condition, results from operations, and cash flows.

Technological developments and increased competition could affect the Company’s operating profit mar-
gins and sales volume.

The Company competes in an industry where technology and innovation play major roles in the competitive
landscape. The Company is highly engaged in the investigation, development, and implementation of new
technologies. Securing key partnerships and alliances as well as employee talent, including having access to
technologies developed by others, and the obtaining of appropriate patents play a significant role in protecting the
Company’s intellectual property and development activities. Additionally, the continual development of new
technologies (e.g., LED, OLED, lamp/ballast systems, lighting controls systems, etc.) by existing and new source
suppliers — including non-traditional competitors with significant resources — looking for either direct market
access or partnership with competing large manufacturers, coupled with significant associated exclusivity and/or
patent activity, could adversely affect the Company’s ability to sustain operating profit margin and desirable levels
of sales volume. Consolidation remains a key trend. Certain broader and more global electrical manufacturers may
be able to obtain a competitive advantage over the Company by offering broader and more integrated electrical
solutions utilizing electrical, lighting, and building automation products.

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

Relationships forged with customers, including The Home Depot which historically has represented slightly
greater than 10% of the Company’s total net sales, are directly impacted by the Company’s ability to deliver
high-quality products and services. The Company does not have a written contract obligating The Home Depot to
purchase its products. The loss of or substantial decrease in the volume of purchases by The Home Depot would
harm the Company’s sales, profitability and cash flow. The Company also has relationships with channel partners
such as electrical distributors and independent sale agencies. While the Company has experienced positive, and in
most cases long-term, relationships with these channel partners, the loss of some 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, at least in the short-term, adversely affect the Company’s sales, profitability, and cash flows.

If Acuity Brands’ products are improperly designed, manufactured, packaged, or labeled, the Company may
need to recall those items and could be the target of product liability claims if consumers are injured.

The Company may need to recall products if they are improperly designed, manufactured, packaged, or
labeled and does not maintain insurance for such events. The Company’s quality control procedures relating to the
raw materials, including packaging, that it receives from third-party suppliers, as well as the Company’s quality
control procedures relating to its products after those products are designed, manufactured, and packaged, may not
be sufficient. The Company has previously initiated product recalls as a result of potentially faulty components,
assembly, installation, and packaging of its products, and widespread product recalls could result in significant
losses due to the costs of a recall, the destruction of product inventory, and lost sales due to the unavailability of
product for a period of time. The Company may also be liable if the use of any of its products causes injury, and
could suffer losses from a significant product liability judgment against the Company. A significant product recall
or product liability case could also result in adverse publicity, damage to the Company’s reputation, and a loss of

12

consumer confidence in its products, which could have a material adverse effect on the Company’s business,
financial results, and cash flows.

Acuity Brands could be adversely affected by disruptions of its operations.

The breakdown of equipment or other events, including labor disputes, pandemics or catastrophic events such as
war or natural disasters, leading to production interruptions in the Company’s or one or more of its suppliers’ plants could
have a material adverse effect on the Company’s financial results and cash flows. Approximately 50% of the Company’s
sales of finished products are manufactured in Mexico, a country that is currently experiencing heightened civil unrest,
which could also disrupt supply of products from these facilities. Further, because many of the Company’s customers are,
to varying degrees, dependent on planned deliveries from the Company’s plants, those customers that have to reschedule
their own production or delay opening a facility due to the Company’s missed deliveries could pursue financial claims
against the Company. The Company may incur costs to correct any of these problems, in addition to facing claims from
customers. Further, the Company’s reputation among actual and potential customers may be harmed and result in a loss
of business. While the Company has developed business continuity plans to support responses to such events or
disruptions and maintains insurance policies covering, among other things, physical damage and business interruptions,
these policies may not cover all losses. The Company could incur uninsured losses and liabilities arising from such
events, including damage to its reputation, loss of customers, and substantial losses in operational capacity, any of which
could have a material adverse effect on its financial results and cash flows.

Failure of a Company operating or information system or a compromise of security with respect to an operat-
ing or information system or portable electronic device could adversely affect the Company’s results from oper-
ations and financial condition or the effectiveness of internal controls over operations and financial reporting.

The Company is highly dependent on automated systems to record and process Company and customer
transactions and certain other components of the Company’s financial statements. The Company could experience a
failure of one or more of these systems or could fail to complete all necessary data reconciliation or other conversion
controls when implementing a new software system. The Company could also experience a compromise of its security
due to technical system flaws, clerical, data input or record-keeping errors, or tampering or manipulation of those
systems by employees or unauthorized third parties. 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. The
Company may also be subject to disruptions of any of these systems arising from events that are wholly or partially
beyond its control (for example, natural disasters, acts of terrorism, epidemics, computer viruses, and electrical/
telecommunications outages). All of these risks are also applicable where the Company relies on outside vendors to
provide services to it. Operating system failures, ineffective system implementation or disruptions, or the compromise
of security with respect to operating systems or portable electronic devices could subject the Company to liability
claims, harm the Company’s reputation, interrupt the Company’s operations, and adversely affect the Company’s
internal control over financial reporting, business, results from operations, financial condition or cash flow.

The inability to attract and retain talented employees and/or a loss of key employees could adversely
affect the effectiveness of the Company’s operations.

The Company relies upon the knowledge and experience of employees involved in functions throughout the
organization that require technical expertise and knowledge of the industry. A loss of such employees could
adversely impact the Company’s ability to execute key operational functions and could adversely affect the
Company’s operations.

The risks associated with the inability to effectively execute its strategies could adversely affect the Com-
pany’s results from operations and financial condition.

Various uncertainties and risks are associated with the implementation of a number of aspects of the
Company’s global business strategy, including but not limited to new product development, effective integration
of acquisitions, and efforts to streamline operations. Those uncertainties and risks include, but are not limited to:
diversion of management’s attention; difficulty in retaining or attracting employees; negative impact on relation-
ships with distributors and customers; obsolescence of current products and slow new product development;

13

additional streamlining efforts; 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, and could adversely affect the Company’s financial condition and results from operations.

Risks Related to Ownership of Acuity Brands Common Stock

The market price and trading volume of the Company’s shares may be volatile.

The market price of the Company’s common shares could fluctuate significantly for many reasons, including
for reasons unrelated to the Company’s 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 economic and industry conditions. For example, to the extent that other large companies within
the Company’s industry experience declines in their share price, the Company’s 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 the company. A lawsuit against the Company could cause the Company to incur
substantial costs and could divert the time and attention of the Company’s management and other resources.

Risks Related to the Spin-off of Zep Inc.

Failure of the distribution to qualify as a tax-free transaction could result in substantial liability.

Acuity Brands has received a private letter ruling from the Internal Revenue Service (“IRS”) to the effect that,
among other things, the Spin-off (including certain related transactions) qualifies as tax-free to Acuity Brands, Zep,
and Acuity Brands’ stockholders for United States federal income tax purposes under section 355 and related
provisions of the Internal Revenue Code (“IRC”). Although a private letter ruling generally is binding on the IRS, if
the factual assumptions or representations made in the private letter ruling request are untrue or incomplete in any
material respect, then Acuity Brands will not be able to rely on the ruling. Moreover, the IRS will not rule on
whether a distribution of shares satisfies certain requirements necessary to obtain tax-free treatment under
section 355 of the IRC. Rather, the private letter ruling is based upon representations by Acuity Brands that
those requirements have been satisfied, and any inaccuracy in those representations could invalidate the ruling.

Acuity Brands has received an opinion of King & Spalding LLP, counsel to Acuity Brands, to the effect that,
with respect to the requirements referred to above on which the IRS will not rule, those requirements will be
satisfied. The opinion is based on, among other things, certain assumptions and representations as to factual matters
made by Acuity Brands and Zep which, if untrue or incomplete in any material respect, could jeopardize the
conclusions reached by counsel in its opinion. The opinion is not binding on the IRS or the courts, and the IRS or the
courts may not agree with the opinion.

If the Spin-off fails to qualify for tax-free treatment, a substantial corporate tax would be payable by Acuity
Brands, measured by the difference between (1) the aggregate fair market value of the shares of Zep common stock
on the date of the Spin-off and (2) Acuity Brands’ adjusted tax basis in the shares of Zep common stock on the date
of the Spin-off. The corporate level tax would be payable by Acuity Brands. However, Zep has agreed, under certain
circumstances, to indemnify Acuity Brands for this tax liability. In addition, under the applicable Treasury
regulations, each member of Acuity Brands’ consolidated group at the time of the Spin-off (including Zep) is
severally liable for such tax liability.

Furthermore, if the Spin-off does not qualify as tax-free, each Acuity Brands stockholder generally would be
taxed as if he or she had received a cash distribution equal to the fair market value of the shares of Zep common
stock on the date of the Spin-off.

Even if the Spin-off otherwise qualifies as tax-free, Acuity Brands nevertheless could incur a substantial
corporate tax liability under section 355(e) of the IRC, if 50 percent or more of the stock of Acuity Brands or Zep
were to be acquired as part of a “plan (or a series of related transactions)” that includes the distribution. For this
purpose, any acquisitions of the stock of Acuity Brands or of Zep stock that occurred within two years before or
after the Spin-off are presumed to be part of such a plan, although Acuity Brands may be able to rebut that
presumption. If such an acquisition of the stock of Acuity Brands or of Zep stock triggers the application of
section 355(e), Acuity Brands would recognize taxable gain as described above, but the Spin-off would generally

14

remain tax-free to the Acuity Brands stockholders. If acquisitions of Zep’s stock trigger the application of
section 355(e), Zep would be obligated to indemnify Acuity Brands for the resulting corporate-level tax liability.

Item 2. Properties

The general corporate offices of Acuity Brands are located in Atlanta, Georgia. Because of the diverse nature
of operations and the large number of individual locations, it is neither practical nor meaningful to describe each of
the operating facilities owned or leased by the Company. The following listing summarizes the significant facility
categories:

None of the individual properties of Acuity Brands is considered to have a value that is significant in relation to
the assets of Acuity Brands as a whole. Though a loss at certain facilities could have an impact on the Company’s
ability to serve the needs of its customers, the Company believes that the financial impact would be partially
mitigated by various insurance programs in place. Acuity Brands believes that its properties are well maintained and
are in good operating condition and that its properties are suitable and adequate for its present needs. The Company
believes that it has additional capacity available at most of its production facilities and that it could increase
production without substantial capital expenditures. As noted above, initiatives related to enhancing the global
supply chain may continue to result in the consolidation of certain manufacturing facilities. However, the Company
believes that the remaining facilities will have sufficient capacity to serve current and projected market demand.

Item 3. Legal Proceedings

General

Acuity Brands is subject to various legal claims arising in the normal course of business, including patent
infringement and product liability claims. Acuity Brands is self-insured up to specified limits for certain types of
claims, including product liability, and is fully self-insured for certain other types of claims, including environ-
mental, product recall, and patent infringement. Based on information currently available, it is the opinion of
management that the ultimate resolution of pending and threatened legal proceedings will not have a material
adverse effect on the financial condition, results of operations, or cash flows of Acuity Brands. However, in the
event of unexpected future developments, it is possible that the ultimate resolution of any such matters, if
unfavorable, could have a material adverse effect on the financial condition, results of operations, or cash flows of
Acuity Brands in future periods. Acuity Brands establishes reserves 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 than the amounts reserved for such claims. However, the Company cannot make a meaningful
estimate of actual costs to be incurred that could possibly be higher or lower than the amounts reserved.

15

Environmental Matters

The operations of the Company are subject to numerous comprehensive laws and regulations relating to the
generation, storage, handling, transportation, and disposal of hazardous substances, as well as solid and hazardous
wastes, and to the remediation of contaminated sites. In addition, permits and environmental controls are required
for certain of the Company’s operations to limit air and water pollution, and these permits are subject to
modification, renewal, and revocation by issuing authorities. On an ongoing basis, Acuity Brands invests capital
and incurs operating costs relating to environmental compliance. Environmental laws and regulations have
generally become stricter in recent years. The cost of responding to future changes may be substantial. Acuity
Brands establishes reserves for known environmental claims when the costs associated with the claims become
probable and can be reasonably estimated. The actual cost of environmental issues may be substantially higher or
lower than that reserved due to difficulty in estimating such costs.

The Company plans to pay quarterly dividends for fiscal 2011 on its common stock at an annual rate of $0.52
per share. All decisions regarding the declaration and payment of dividends are at the discretion of the Board of
Directors of the Company and will be evaluated from time to time in light of the Company’s financial condition,
earnings, growth prospects, funding requirements, applicable law, and any other factors that the Company’s Board
deems relevant. The information required by this item with respect to equity compensation plans is included under
the caption Equity Compensation Plans in the Company’s proxy statement for the annual meeting of stockholders to
be held January 7, 2011, to be filed with the Securities and Exchange Commission pursuant to Regulation 14A, and
is incorporated herein by reference.

During fiscal 2010, the Company reacquired approximately 512,300 shares of the Company’s outstanding
common stock, which completed the repurchase of 10 million shares previously authorized by the Board of
Directors. In July 2010, the Company’s Board of Directors authorized the repurchase of an additional two million
shares, or almost 5%, of the Company’s outstanding common stock. Approximately 535,500 shares were
repurchased in fiscal 2010 under this plan.

During fiscal 2009, the Company reissued 2.1 million shares from treasury stock as partial consideration for
the acquisitions of Sensor Switch, Inc. (“Sensor Switch”) and Lighting Controls & Design, Inc. (“LC&D”). As part

16

of the merger agreement, the Company reissued slightly more than 140,000 shares from treasury stock as partial
consideration for the acquisition of LC&D during the current fiscal year.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations
($ in millions, except per-share data and as indicated)

The following discussion should be read in conjunction with the Consolidated Financial Statements and

related notes included within this report. References made to years are for fiscal year periods.

The purpose of this discussion and analysis is to enhance the understanding and evaluation of the results of
operations, financial position, cash flows, indebtedness, and other key financial information of Acuity Brands and
its subsidiaries for the years ended August 31, 2010 and 2009. For a more complete understanding of this discussion,
please read the Notes to Consolidated Financial Statements included in this report.

Overview

Company

Acuity Brands is the parent company of Acuity Brands Lighting, Inc. (“ABL”), and other subsidiaries
(collectively referred to herein as “the Company”). The Company, with its principal office in Atlanta, Georgia,
employs approximately 6,000 people worldwide.

The Company designs, produces, and distributes a broad array of indoor and outdoor lighting fixtures, control
devices, components, systems, and services for commercial and institutional, industrial, infrastructure, and
residential applications for various markets throughout North America and select international markets. The
Company is one of the world’s leading producers and distributors of lighting fixtures, with a broad, highly
configurable product offering, consisting of roughly 500,000 active products as part of over 2,000 product groups,
as well as lighting controls and other products, that are sold to approximately 5,000 customers. As of August 31,
2010, the Company operates 16 manufacturing facilities and six distribution facilities along with three warehouses
to serve its extensive customer base.

On October 14, 2010, the Company acquired for cash all of the outstanding capital stock of Winona Lighting,
Inc. (“Winona Lighting”), a premier provider of architectural and high-performance indoor and outdoor lighting
products headquartered in Minnesota. Recognized throughout the architectural design community, Winona
Lighting served the commercial, retail, and institutional markets with a product portfolio of high-quality and
design-oriented luminaires suitable for decorative, custom, asymmetric, and landscape lighting applications. As
this acquisition occurred after August 31, 2010, the operating results for Winona Lighting have not been included in
the Company’s consolidated financial statements.

On July 26, 2010, the Company acquired the remaining outstanding capital stock of Renaissance Lighting, Inc.
(“Renaissance”), a privately-held, pioneering innovator of solid-state light-emitting diode (“LED”) architectural
lighting. Renaissance, based in Herndon, Virginia, offered a full range of LED-based specification-grade down-
lighting luminaires and developed an extensive intellectual property portfolio related to advanced LED optical
solutions and technologies. Previously, the Company entered into a strategic partnership with Renaissance, which
included a noncontrolling interest in Renaissance and a license to Renaissance’s intellectual property estate. The
operating results of Renaissance have been included in the Company’s consolidated financial statements since the
date of acquisition.

On April 20, 2009, the Company acquired 100% of the outstanding capital stock of Sensor Switch, Inc.
(“Sensor Switch”), an industry-leading developer and manufacturer of lighting controls and energy management
systems. Sensor Switch, based in Wallingford, Connecticut, offered a wide-breadth of products and solutions that
substantially reduce energy consumption, including occupancy sensors, photocontrols, and distributed lighting
control devices. The operating results of Sensor Switch have been included in the Company’s consolidated financial
statements since the date of acquisition.

On December 31, 2008, the Company acquired for cash and stock substantially all the assets and assumed
certain liabilities of Lighting Controls & Design (“LC&D”). Located in Glendale, California, LC&D is a
manufacturer of comprehensive digital lighting controls and software that offered a breadth of products, ranging
from dimming and building interfaces to digital thermostats, all within a single, scalable system. The operating

18

results of LC&D have been included in the Company’s consolidated financial statements since the date of
acquisition.

Acuity Brands completed the Spin-off of its specialty products business, Zep, on October 31, 2007, by
distributing all of the shares of Zep common stock, par value $.01 per share, to the Company’s stockholders of
record as of October 17, 2007. The Company’s stockholders received one Zep share, together with an associated
preferred stock purchase right, for every two shares of the Company’s common stock they owned. Stockholders
received cash in lieu of fractional shares for amounts less than one full Zep share.

As a result of the Spin-off, the Company’s financial statements have been prepared with the net assets, results
of operations, and cash flows of the specialty products business presented as discontinued operations. All historical
statements have been restated to conform to this presentation.

Strategy

Our strategy is to extend our market leadership position by delivering superior lighting solutions. As a goal-
oriented, market-driven company, we will continue to align the unique capabilities and resources of our organi-
zation to drive profitable growth through a keen focus on providing differentiated lighting solutions for our
customers, driving world-class cost efficiency, and leveraging a culture of continuous improvement.

Throughout 2010, the Company believes it made significant progress towards achieving its strategic objec-
tives, including expanding its access to market, introducing new products and lighting solutions, and enhancing its
operations to create a stronger, more effective organization. The strategic objectives were developed to enable the
Company to meet or exceed the following financial goals during an entire business cycle:

(cid:129) Operating margins in excess of 12%;

(cid:129) Earnings per share growth in excess of 15% per annum;

(cid:129) Return on stockholders’ equity of 20% or better per annum; and

(cid:129) Cash flow from operations, less capital expenditures, that is in excess of net income.

To increase the probability of the Company achieving these financial goals, management will continue to
implement programs to enhance its capabilities at providing unparalleled customer service; creating a globally
competitive cost structure; improving productivity; and introducing new and innovative products and services more
rapidly and cost effectively. In addition, the Company has invested considerable resources to teach and train
associates to utilize tools and techniques that accelerate success in these key areas, as well as to create a culture that
demands excellence through continuous improvement. Additionally, the Company promotes a “pay-for-perform-
ance” culture that rewards achievement, while closely monitoring appropriate risk-taking. The expected outcome of
these activities will be to better position the Company to deliver on its full potential, to provide a platform for future
growth opportunities, and to allow the Company to achieve its long-term financial goals. See the Outlook section
below for additional information.

Liquidity and Capital Resources

The Company’s principle sources of liquidity are operating cash flows generated primarily from its business
operations, cash on hand, and various sources of borrowings. The ability of the Company to generate sufficient cash
flow from operations and access certain capital markets, including banks, is necessary to fund its operations, to pay
dividends, to meet its obligations as they become due, and to maintain compliance with covenants contained in its
financing agreements.

In December 2009, the Company strengthened its liquidity position and extended its debt maturity profile
following the issuance of $350.0 of senior unsecured notes due in fiscal 2020, as more fully described below under
the Capitalization section.

Based on its cash on hand, availability under existing financing arrangements and current projections of cash
flow from operations, the Company believes that it will be able to meet its liquidity needs over the next 12 months.
These needs are expected to include funding its operations as currently planned, making anticipated capital

19

investments, funding certain potential acquisitions, funding foreseen improvement initiatives, paying quarterly
stockholder dividends as currently anticipated, paying interest on borrowings as currently scheduled, and making
required contributions into its employee benefit plans, as well as potentially repurchasing shares of its outstanding
common stock as authorized by the Board of Directors. The Company currently expects to invest during fiscal 2011
up to $40.0 primarily for equipment, tooling, and new and enhanced information technology capabilities.

Cash Flow

The Company uses available cash and cash flow from operations, as well as proceeds from the exercise of stock
options, to fund operations and capital expenditures, repurchase stock, fund acquisitions, and pay dividends. The
Company’s cash position at August 31, 2010 was $191.0, an increase of $172.3 from August 31, 2009. In addition to
$160.5 of net cash generated from operating activities during fiscal 2010, net proceeds from refinancing activities
completed in the second quarter of fiscal 2010, as more fully described below under the Capitalization section,
contributed $108.6 to the increase in the cash position, which was partially offset by stock repurchases of $36.1,
dividends to stockholders of $22.6, acquisitions (net of cash assumed) and strategic investments of $22.6, and
capital expenditures of $21.9.

During fiscal 2010, the Company generated $160.5 of net cash from operating activities compared with $92.7
generated in the prior-year period, an increase of $67.8. The prior-year period’s net cash from operating activities
was negatively impacted by a decrease in other current liabilities due primarily to the payment of employee
incentive compensation, which was attributable to record performance in fiscal 2008. Due to the sizable decline in
the Company’s end-markets during fiscal 2009 and the resulting volume decline in sales and operating activities,
cash in the prior-year period was negatively impacted by the decline in accounts payable and lower other current
liabilities as previously noted, partially offset by a decline in accounts receivable. In comparison, the current year
net cash from operating activities were not impacted to the extent as fiscal 2009 due to the relatively minor changes
in operating working capital based on higher sales during the second half of fiscal 2010 and the drastically lower
payouts of employee incentive compensation during fiscal 2010, which was attributable to fiscal 2009 performance.

Operating working capital (calculated by adding accounts receivable, net, plus inventories, and subtracting
accounts payable) as a percentage of net sales increased to 12.9% at the end of fiscal 2010 from 12.4% at the end of
fiscal 2009, due primarily to the effects of higher net sales during the fourth quarter of fiscal 2010 as compared to the
prior-year period. At August 31, 2010, the current ratio (calculated as total current assets divided by total current
liabilities) of the Company was 1.9 compared with 0.9 at August 31, 2009. This improvement in the current ratio
during fiscal 2010 was due primarily to the increase in cash as described above and the repayment of the $200.0 of
publicly traded notes that were scheduled to mature in August 2010 (the “2010 Notes”).

Management believes that investing in assets and programs that will over time increase the overall return on its
invested capital is a key factor in driving stockholder value. The Company invested $21.9 and $21.2 in fiscal 2010
and 2009, respectively, primarily for new tooling, machinery, equipment, and information technology. As noted
above, the Company expects to invest up to $40.0 for new plant, equipment, tooling, and new and enhanced
information technology capabilities during fiscal 2011.

(1) These amounts (which represent the amounts outstanding at August 31, 2010) are included in the Company’s
Consolidated Balance Sheets. See the Debt and Lines of Credit footnote for additional information regarding
debt and other matters.

(2) These amounts represent the expected future interest payments on outstanding debt held by the Company at
August 31, 2010 and the Company’s outstanding loans related to its corporate-owned life insurance policies
(“COLI”). COLI-related interest payments included in this table are estimates. These estimates are based on
various assumptions, including age at death, loan interest rate, and tax bracket. The amounts in this table do not
include COLI-related payments after ten years due to the difficulty in calculating a meaningful estimate that far
in the future. Note that payments related to debt and the COLI are reflected on the Company’s Consolidated
Statements of Cash Flows.

(3) The Company’s operating lease obligations are described in the Commitments and Contingencies footnote.

(4) Purchase obligations include commitments to purchase goods or services that are enforceable and legally

binding and that specify all significant terms, including open purchase orders.

(5) These amounts are included in the Company’s Consolidated Balance Sheets and largely represent other
liabilities for which the Company is obligated to make future payments under certain long-term employee
benefit programs. Estimates of the amounts and timing of these amounts are based on various assumptions,
including expected return on plan assets, interest rates, and other variables. The amounts in this table do not
include amounts related to future funding obligations under the defined benefit pension plans. The amount and
timing of these future funding obligations are subject to many variables and also depend on whether or not the
Company elects to make contributions to the pension plans in excess of those required under ERISA. Such
voluntary contributions may reduce or defer the funding obligations. See the Pension and Profit Sharing Plans
footnote for additional information. These amounts exclude $6.7 of unrecognized tax benefits as a reasonable
estimate of the period of cash settlement with the respective taxing authorities cannot be determined.

Capitalization

The current capital structure of the Company is comprised principally of senior notes and equity of its
stockholders. As of August 31, 2010, total debt outstanding increased $121.8 to $353.3 compared with $231.5 at
August 31, 2009, due primarily to the issuance of debt further explained below, partially offset by the redemption of
the 2010 Notes and the repayment of principal on a three-year 6% unsecured promissory note issued to the former
sole shareholder of Sensor Switch.

On December 8, 2009, ABL issued $350.0 of senior unsecured notes due in fiscal 2020 (the “Notes”) in a
private placement transaction. As described below, the Notes were subsequently exchanged for SEC-registered
notes with substantially identical terms. The Notes bear interest at a rate of 6% per annum and were issued at a price
equal to 99.797% of their face value and for a term of 10 years. A portion of the net proceeds from the issuance of the
Notes were used to retire the 2010 Notes. Additionally, management retired, without premium or penalty, the
remaining $25.3 outstanding balance on the promissory note issued to the former sole shareholder of Sensor Switch.

The Notes are fully and unconditionally guaranteed on a senior unsecured basis by Acuity Brands and ABL IP
Holding LLC (“ABL IP Holding”, and, together with Acuity Brands, the “Guarantors”), a wholly-owned subsidiary
of Acuity Brands. The Notes are senior unsecured obligations of ABL and rank equally in right of payment with all
of ABL’s existing and future senior unsecured indebtedness. The guarantees of Acuity Brands and ABL IP Holding
are senior unsecured obligations of Acuity Brands and ABL IP Holding and rank equally in right of payment with
their other senior unsecured indebtedness. Interest on the Notes is payable semi-annually on June 15 and
December 15, which commenced on June 15, 2010.

In accordance with the registration rights agreement by and between ABL and the Guarantors and the initial
purchasers of the Notes, ABL and the Guarantors to the Notes filed a registration statement with the SEC for an offer
to exchange the Notes for SEC-registered notes with substantially identical terms. The registration became effective
on August 17, 2010, and all of the Notes were exchanged.

As noted above, the Company retired all of the outstanding 2010 Notes through the execution of a cash tender
offer and the subsequent redemption of any remaining 2010 Notes during fiscal 2010. The loss on the transaction,

21

including the premium paid, expenses, and the write-off of deferred issuance costs associated with the 2010 Notes,
was approximately $10.5.

As a result of the second quarter financing activities, which included the issuance and exchange of the Notes,
the retirement of the 2010 Notes, and the prepayment of the unsecured promissory note, the Company increased
both its liquidity and debt positions, greatly extended its debt maturity profile, and lowered its average interest rate
on outstanding debt. The Company expects to subsequently incur increased interest expense for the foreseeable
reporting periods based on the higher outstanding debt balance as compared with prior periods, partially offset by
the lower interest rate on the Notes as compared with the 2010 Notes. The Company also capitalized an estimated
$3.1 of deferred issuance costs related to the Notes that are being amortized over the 10-year term of the Notes.

On October 19, 2007, the Company executed a $250.0 revolving credit facility (the “Revolving Credit
Facility”). The Revolving Credit Facility matures in October 2012 and contains financial covenants including a
minimum interest coverage ratio and a leverage ratio (“Maximum Leverage Ratio”) of total indebtedness to
EBITDA (earnings before interest, taxes, depreciation, and amortization expense), as such terms are defined in the
Revolving Credit Facility agreement. These ratios are computed at the end of each fiscal quarter for the most recent
12-month period. The Revolving Credit Facility allows for a Maximum Leverage Ratio of 3.50, subject to certain
conditions defined in the financing agreement. As of August 31, 2010, the Company was compliant with all
financial covenants under the Revolving Credit Facility. At August 31, 2010, the Company had additional
borrowing capacity under the Revolving Credit Facility of $242.7 under the most restrictive covenant in effect
at the time, which represents the full amount of the Revolving Credit Facility less outstanding letters of credit of
$7.3.

During fiscal 2010, the Company’s consolidated stockholders’ equity increased $22.2 to $694.4 at August 31,
2010 from $672.2 at August 31, 2009. The increase was due primarily to net income earned in the period, as well as
amortization of stock-based compensation, and stock issuances resulting primarily from the exercise of stock
options, partially offset by repurchases of common stock, payment of dividends, pension plan adjustments, and
foreign currency translation adjustments. The Company’s debt to total capitalization ratio (calculated by dividing
total debt by the sum of total debt and total stockholders’ equity) was 33.7% and 25.6% at August 31, 2010 and
August 31, 2009, respectively. The second quarter financing activities, which include the issuance of the $350.0 of
Notes and the early retirement of the $200.0 of 2010 Notes, increased the debt to total capitalization ratio. The ratio
of debt, net of cash, to total capitalization, net of cash, was 18.9% at August 31, 2010 and 24.1% at August 31, 2009.

Dividends

Acuity Brands paid dividends on its common stock of $22.6 ($0.52 per share) during 2010 compared with
$21.6 ($0.52 per share) in 2009. Acuity Brands currently plans to pay quarterly dividends at a rate of $0.13 per
share. All decisions regarding the declaration and payment of dividends by Acuity Brands are at the discretion of the
Board of Directors of Acuity Brands and will be evaluated from time to time in light of the Company’s financial
condition, earnings, growth prospects, funding requirements, applicable law, and any other factors the Acuity
Brands’ Board deems relevant.

Results from Continuing Operations

Net sales were $1,626.9 for fiscal 2010 compared with $1,657.4 for fiscal 2009, a decrease of $30.5, or
approximately 2%. For fiscal 2010, the Company reported income from continuing operations of $79.0 compared
with $85.2 earned in the prior-year period. Diluted earnings per share from continuing operations for fiscal 2010
decreased 10.9% to $1.79 from $2.01 for the prior-year period. Results for fiscal 2010 and 2009 include after-tax
special charges of $5.5 and $16.8, respectively, related to estimated costs to be incurred to simplify and streamline
operations and to consolidate certain manufacturing facilities. In addition, a $6.8 after-tax loss associated with the
early extinguishment of debt was incurred during the second quarter of fiscal 2010. The special charges and loss on
early extinguishment of debt negatively impacted fiscal 2010 results by $0.29 per diluted share; special charges
recorded in the prior year negatively impacted the fiscal 2009 results by $0.40 per diluted share.

The table below reconciles certain U.S. generally accepted accounting principles (“U.S. GAAP”) financial
measures to the corresponding non-U.S. GAAP measures, which exclude special charges associated with actions to
streamline the organization, including the consolidation of certain manufacturing facilities, and the loss on the early
extinguishment of debt. These non-U.S. GAAP financial measures, including adjusted operating profit, adjusted
operating profit margin, adjusted income from continuing operations, and adjusted diluted earnings per share from
continuing operations, are provided to enhance the user’s overall understanding of the Company’s current financial
performance. Specifically, the Company believes these non-U.S. GAAP measures provide greater comparability
and enhanced visibility into the results of operations, excluding the impact of the special charges and loss on the
early extinguishment of debt. These non-U.S. GAAP financial measures should be considered in addition to, and
not as a substitute for or superior to, results prepared in accordance with U.S. GAAP.

Net Sales

Net sales for the fiscal year ended August 31, 2010, declined approximately 2% compared with fiscal 2009.
Market conditions remained challenging in fiscal 2010 with new U.S. non-residential construction declining 15%
compared to the prior year due to weak economic conditions. Approximately 4% of the comparative annual decline
in sales was due to unfavorable changes in product prices and the mix of products sold (“price/mix”), particularly in
the non-residential commercial and industrial channel and certain international markets. Although it is not possible
to precisely quantify the separate impact of price and product mix changes, the Company estimates that a majority
of the decline was due to lower product selling prices in certain channels and geographies. Higher sales volume
primarily related to the additional sales from acquired businesses and other investments made by the Company
partially offset the negative impact of price/mix on net sales. The acquisitions of the lighting controls businesses in
the prior year contributed approximately 3% in incremental net sales during the current year. In addition, the
translation impact of the stronger dollar on international sales contributed approximately one percentage point to
current year net sales.

Gross Profit

Fiscal 2010 gross profit margin increased by 240 basis points to 40.7% of net sales compared with 38.3%
reported for the prior-year period. Gross profit for fiscal 2010 increased $26.4, or 4.2%, to $661.5 compared with
$635.1 for the prior-year period. The increase was due primarily to lower materials and components costs, savings
from streamlining actions, and favorable contributions from acquired businesses. These benefits were partially
offset by the impact of lower pricing, unfavorable product mix, and higher pension and transportation costs.

24

Operating Profit

Selling, Distribution, and Administrative (“SD&A”) expenses for fiscal 2010 were $495.4 compared with
$454.6 in the prior-year period, which represented a $40.8, or 9.0%, year-over-year increase. SD&A expenses as a
percent of sales increased by 310 basis points to 30.5% for fiscal 2010. More than half of the year-over-year increase
was due to higher incentive compensation due to current year performance relative to the Company’s served
markets, as well as severely curtailed incentives earned in the prior fiscal year. The remainder of the increase in
SD&A expenses was due primarily to higher commission and freight costs, selected investments in sales and
marketing resources and new products and services, and structurally higher operating costs associated with acquired
businesses.

As part of the Company’s initiative to streamline and simplify operations, the Company recorded in fiscal 2010
and 2009 pre-tax charges of $8.4 and $26.7, respectively, to reflect severance and related employee benefit costs
associated with the consolidation of certain manufacturing facilities and a reduction in workforce, as well as non-
cash asset impairment charges on certain assets related to those manufacturing facilities. The pre-tax, non-cash
asset impairment charges for fiscal 2010 and 2009 were $5.1 and $1.6, respectively. The Company realized
approximately $50.0 ($28.0 during fiscal 2009 and an additional $22.0 during fiscal 2010) in annualized benefits
related to these streamlining actions, which were initiated in fiscal 2009.

Operating profit for fiscal 2010 was $157.7 compared with $153.8 reported for the prior-year period, an
increase of $3.9, or 2.5%. Operating profit margin increased 40 basis points to 9.7% compared with 9.3% in the
year-ago period. The increase was due primarily to the higher gross profit as noted above and the decrease in the
special charge, partially offset by the increase in SD&A expenses as a percentage of net sales as discussed above.

Excluding the special charge in both periods, adjusted operating profit for fiscal 2010 decreased $14.4, or
8.0%, to $166.1 compared with $180.5 in fiscal 2009. Adjusted operating profit margin for fiscal 2010 of 10.2% was
70 basis points lower than the prior year’s adjusted margin of 10.9%. The decrease was due primarily to higher
SD&A expenses as explained above.

Income from Continuing Operations before Provision for Taxes

Other expense (income) for the Company consists primarily of net interest expense and foreign exchange
related gains and losses. Interest expense, net, was $29.4 and $28.5 for fiscal 2010 and 2009, respectively. The
modest increase in interest expense, net, was due primarily to higher interest costs related to obligations associated
with non-qualified retirement plans, while lower year-over-year interest expense on borrowings was largely offset
by lower interest income — both of which were impacted by lower rates. Miscellaneous income for fiscal 2010 of
$1.0 declined from the $2.0 reported in the prior-year period. The decline in miscellaneous income was due
primarily to the impact of changes in exchange rates on foreign currency items.

Due to the early retirement of the 2010 Notes in the second quarter of fiscal 2010, the Company recognized a

pre-tax loss of $10.5 during the fiscal year.

Provision for Income Taxes and Income from Continuing Operations

The effective income tax rate reported by the Company was 33.5% and 33.1% for fiscal 2010 and 2009,
respectively. The discrete items for fiscal 2010, including federal tax credits, favorable state audit settlements, and
benefits from increased export of goods manufactured in the U.S., were slightly lower than those experienced in the
prior-year period. The Company estimates that the effective tax rate for fiscal year 2011 will be approximately 34%
if the rates in its taxing jurisdictions remain generally consistent throughout the year.

Income from continuing operations for fiscal 2010 decreased $6.2 to $79.0 (including $12.3 for the after-tax
special charge and loss on early debt extinguishment) from $85.2 (including $16.8 for the after-tax special charge)
reported for the prior-year period. The decrease in income from continuing operations resulted primarily from the
loss on the early debt extinguishment, partially offset by slightly higher operating profit.

Excluding the special charge in both periods and the loss on the early extinguishment of debt reported in fiscal
2010, adjusted income from continuing operations for fiscal 2010 was $91.3 compared with $102.0 in the year-ago
period, a decrease of $10.7, or 10.5%. The year-over-year decline in adjusted income from continuing operations

25

was due primarily to higher SD&A expenses. Excluding the special charges and the loss on the early extinguish-
ment of debt, adjusted diluted earnings per share from continuing operations for fiscal 2010 was $2.08 compared
with $2.41 for the prior-year period. In addition to the items noted above that impacted adjusted income from
continuing operations, adjusted diluted earnings per share from continuing operations for the current fiscal year
were negatively impacted by an increase in the number of shares outstanding compared with the prior-year period.
The increase in the average shares outstanding was due primarily to shares issued as partial consideration for the
acquisitions of Sensor Switch and LC&D, partially offset by the share repurchases during the fourth quarter of fiscal
2010.

Results from Discontinued Operations and Net Income

The Company incurred a $0.6 gain from discontinued operations during fiscal 2010 due to revisions of
estimates of certain legal reserves established at the time of the Spin-off compared with a fiscal 2009 loss from
discontinued operations of $0.3 related to income tax adjustments.

Net income for fiscal 2010 decreased by $5.3, or 6.2%, to $79.6 from $84.9 reported for the prior-year period.
The decrease in net income resulted primarily from the loss on the early debt extinguishment and lower
miscellaneous income, partially offset by the above noted increase in operating profit, lower income tax expense,
and the gain on discontinued operations compared with a loss in the prior-year period.

Results from Continuing Operations

Net sales were $1,657.4 for fiscal 2009 compared with $2,026.6 reported in the prior-year period, a decrease of
$369.2, or 18.2%. For fiscal 2009, the Company reported income from continuing operations of $85.2 compared
with $148.6 earned in fiscal 2008. Diluted earnings per share from continuing operations were $2.01 for fiscal 2009
as compared with $3.51 reported for fiscal 2008, a decrease of 42.7%. Results for fiscal 2009 and 2008 include
after-tax special charges of $16.8 ($26.7 pre-tax), or $0.40 per diluted share, and $9.1 ($14.6 pre-tax), or $0.21 per
diluted share, respectively.

On December 31, 2008, Acuity Brands acquired for cash and stock substantially all the assets and assumed

certain liabilities of LC&D. LC&D had calendar year 2008 sales of approximately $18.0.

On April 20, 2009, the Company acquired Sensor Switch, an industry-leading developer and manufacturer of
lighting controls and energy management systems, for an aggregate consideration of $205.0 comprised of
(i) 2 million shares of common stock of Acuity Brands, (ii) a $30.0 note of Acuity Brands Lighting, and
(iii) approximately $130.0 of cash. A cash payment of approximately $130.0 was funded from available cash on
hand and from borrowings under the Company’s Revolving Credit Facility. The $30.0 unsecured promissory note
was payable over three years. Sensor Switch generated sales in excess of $37.0 during its fiscal year ending
October 31, 2008.

The operating results of Sensor Switch and LC&D have been included in the Company’s consolidated

financial statements since their respective dates of acquisition.

The table below reconciles certain U.S. GAAP financial measures to the corresponding non-U.S. GAAP
measures, which exclude special charges associated with actions to accelerate the streamlining of the organization,
including the consolidation of certain manufacturing facilities. These non-U.S. GAAP financial measures,
including adjusted operating profit, adjusted operating profit margin, adjusted income from continuing operations,
and adjusted diluted earnings per share, are provided to enhance the user’s overall understanding of the Company’s
current financial performance. Specifically, the Company believes these non-U.S. GAAP measures provide greater
comparability and enhanced visibility into the results of operations, excluding the impact of the special charges.
These non-U.S. GAAP financial measures should be considered in addition to, and not as a substitute for or superior
to, results prepared in accordance with U.S. GAAP.

Net Sales

Net sales decreased approximately 18% in 2009 compared with 2008 due primarily to lower shipments and
unfavorable impact of foreign currency fluctuation, partially offset by revenues from recent acquisitions. The lower
volume of product shipments was due primarily to continued decline in demand on the residential and non-
residential construction markets, particularly for commercial and office buildings. The Company estimates
shipment volumes declined by approximately 19% in fiscal 2009 compared with 2008, partially offset by an

27

estimated 1% improvement in price and product mix. Additionally, unfavorable foreign currency rate fluctuations
negatively impacted net sales in fiscal 2009 by slightly less than 2% compared with the prior year, which was
largely offset by $26.0 of net sales from acquisitions.

Gross Profit

Gross profit margin decreased by 200 basis points to 38.3% of net sales for fiscal 2009 from 40.3% reported for
the prior-year period. Gross profit for fiscal 2009 decreased $180.7, or 22.2%, to $635.1 compared with $815.8 for
the prior-year period. The decline in gross profit and gross profit margin was largely attributable to the decline in net
sales noted above, increased cost for raw material and components, and unfavorable foreign currency fluctuations.
The Company estimates raw material and component costs increased cost of goods sold by approximately $40.0
compared with the year-ago period, with only a small portion of the increase recovered in higher prices. Savings
from ongoing streamlining efforts, benefits from productivity improvements, and contributions from acquisitions
helped to partially offset the negative impact of the aforementioned items on gross profit and gross profit margin.

Operating Profit

SD&A expenses for fiscal 2009 were $454.6 compared with $540.1 in the prior-year period, which represented
a decrease of $85.5, or 15.8%. Approximately half of the decrease in SD&A expenses was due to lower
commissions paid to the Company’s sales forces and agents and lower freight costs, which both typically vary
directly with sales. Additionally, reduced incentive compensation and benefits from streamlining efforts contrib-
uted to lower fiscal 2009 SD&A expense. Partially offsetting these reductions was the additional SD&A expenses
related to the businesses acquired in fiscal 2009.

As part of the Company’s initiative to streamline and simplify operations, the Company recorded in fiscal 2009
and 2008 pre-tax charges of $26.7 and $14.6, respectively, to reflect severance and related employee benefit costs
associated with the elimination of certain positions worldwide and the costs associated with the early termination of
certain leases. The fiscal 2009 charge included a non-cash expense of $1.6 for the impairment of assets associated
with the closing of a facility. The Company estimates that it realized $39.0 ($28.0 and $11.0 from actions initiated in
fiscal 2009 and 2008, respectively) in savings during fiscal 2009 compared with the prior year related to these
actions.

Operating profit for fiscal 2009 was $153.8 compared with $261.1 reported for the prior-year period, a
decrease of $107.3, or 41.1%. Operating profit margin decreased 360 basis points to 9.3% compared with 12.9% in
the year-ago period. The decrease in operating profit in fiscal 2009 compared with the prior-year period was due
primarily to the decrease in gross profit noted above and the $12.1 incremental special charge related to
streamlining efforts, partially offset by decreased SD&A expenses as noted above.

Excluding the special charge in both periods, adjusted operating profit for fiscal 2009 decreased $95.2, or
34.5%, to $180.5 compared with $275.7 in fiscal 2008. Adjusted operating profit margin for fiscal 2009 of 10.9%
was 270 basis points lower than prior year’s adjusted margin of 13.6%. The decrease was due to lower volume,
increased raw material and component costs, and unfavorable foreign currency fluctuations, partially offset by
savings from streamlining efforts, benefits from productivity improvements, and contributions from acquisitions.
The Company believes this measure provides greater comparability and enhanced visibility into the improvements
realized.

Income from Continuing Operations before Provision for Taxes

Other expense consists primarily of interest expense, net, and miscellaneous income (or expense) resulting
from changes in exchange rates on foreign currency items as well as other non-operating items. Interest expense,
net, was $28.5 and $28.4 for fiscal 2009 and 2008, respectively. Fiscal 2009 interest expense, net reflects lower
interest expense resulting from the maturity of the $160.0 public notes that was more than offset by reduced interest
income resulting from both lower cash balances and lower short-term interest rates. For fiscal 2009, the Company
reported $2.0 of other miscellaneous income compared with $2.2 of other miscellaneous expense in the year-ago
period. The $4.2 favorable year-over-over change was due primarily to the impact of changes in exchange rates on
foreign currency items.

28

Provision for Income Taxes and Income from Continuing Operations

The effective income tax rate reported by the Company was 33.1% and 35.4% for fiscal 2009 and 2008,
respectively. The decrease in the annual tax rate was due primarily to the greater impact of tax credits and
deductions on the lower earnings amount and the adverse effect on prior year’s effective tax rate related to the
repatriation of foreign cash. Income from continuing operations for fiscal 2009 decreased $63.4 to $85.2 (including
$16.8 after-tax for the special charge) from $148.6 (including $9.1 after-tax for the special charge) reported for the
prior-year period. The decrease in income from continuing operations was due primarily to the above noted
decrease in operating profit, partially offset by lower tax expense.

Excluding the special charge in both periods, adjusted income from continuing operations for fiscal 2009 was
$102.0 compared with $157.7 in the year-ago period, a decrease of $55.7, or 35.3%. The year-over-year decline in
adjusted income from continuing operations was due primarily to the reduction in gross profit, partially offset by
lower SD&A and income tax expenses. Excluding the special charges, adjusted diluted earnings per share from
continuing operations for fiscal 2009 was $2.41 compared with $3.72 for fiscal 2008.

Results from Discontinued Operations and Net Income

The loss from discontinued operations for fiscal 2009 and 2008 was $0.3. The loss in both periods relate to tax

adjustments associated with pre-spin activities.

Net income for fiscal 2009 decreased $63.4 to $84.9 from $148.3 reported for the prior-year period. The

decrease in net income resulted primarily from the above noted decline in net sales.

Outlook

The performance of the Company, like most companies, is influenced by a multitude of factors or the vitality of
the economy, including employment, credit availability and cost, consumer confidence, commodity costs, and
government policy, particularly as it impacts capital formation and risk taking by businesses and commercial
developers. As such, it is difficult at this time to precisely forecast the direction or intensity of future economic
activity in general and more specifically with respect to overall construction demand in fiscal 2011. Key indicators
suggest activity to be slightly down to flat for the North American non-residential construction market during fiscal
2011. However, the potential for energy savings and sustainability may buoy the demand for lighting fixtures and
controls in relation to the renovation of commercial and institutional building and outdoor lighting markets.

Additionally, there is an industry-wide shortage of certain types of electronic ballasts and drivers due to a
global shortage of certain common electronic components, and this has resulted in extended lead times and limited
availability for some ballasts and drivers. This continues to be a concern of management. This situation is expected
to persist for the near future and may adversely impact shipments. The Company has taken steps to procure and
maintain sufficient materials and components stocks in the near term.

While prices for certain materials and components, including steel and petroleum, declined from their record
highs in the summer and fall of 2008, prices for certain materials and components have once again begun to rise,
placing pressure on the Company’s margins. The Company expects to respond to cost increases with higher selling
prices where appropriate, including, but not limited to, the announced price increases on many products effective at
the end of May 2010. However, due to the competitive forces in the current market environment, there can be no
assurance that the Company will be able to pass along all cost increases or adjust prices quickly enough to offset all
or a portion of potentially higher material and component prices. Notwithstanding efforts to recoup potentially
higher costs, management believes pricing will continue to be competitive in certain channels and geographies but
expects the negative impact to be offset through productivity improvements and benefits from new product
introductions.

The Company realized approximately $50.0 of annualized benefits from the streamlining actions taken in
fiscal 2009, of which approximately $28.0 of benefits were realized during fiscal 2009 and an additional $22.0
during fiscal 2010. Also, the Company anticipates additional annualized savings beginning in fiscal 2011 of
approximately $10.0 due to the streamlining efforts announced during the second quarter of fiscal 2010. The
Company projects realized savings at the annualized rate by the second quarter of fiscal 2011. These actions related

29

to the consolidation of certain manufacturing operations and a reduction in workforce. The Company initiated such
actions in an effort to continue to redeploy and invest resources in other areas where the Company believes it can
create greater value and accelerate profitable growth opportunities, including a continued focus on customer
connectivity and industry-leading product innovation incorporating energy-efficiency and sustainable design.

In addition to the recent acquisitions, which significantly increased the Company’s presence in the growing
lighting controls market, management believes the execution of the Company’s strategies to accelerate investments in
innovative and energy-efficient products and services, enhance service to its customers, and expand market presence
in key geographies and sectors such as home centers and the renovation market will provide growth opportunities,
which should enable the Company to continue to outperform the overall markets it serves. The Company believes it is
strategically positioned to take advantage of opportunities within the market, as complete lighting systems will likely
become an integral part of the “smart building” energy management development. Additionally, management believes
these actions and investments will position the Company to meet or exceed its financial goals over the longer term.

The Company expects cash flow from operations to remain strong for fiscal 2011 and intends to invest up to
$40.0 in capital expenditures during the year. In addition, the Company expects to contribute approximately $5.8
and $1.0 to its domestic and international defined benefit plans, respectively, during fiscal 2011. The Company
estimates the annual tax rate to approximate 34% for fiscal 2011.

Although fiscal 2011 results are expected to be negatively impacted by current economic conditions,
management remains positive about the long-term potential of the Company and its ability to outperform the
market. Although management anticipates short-term performance will likely continue to be negatively affected by
further investments in the growing controls and renovation markets, the Company believes that these are necessary
measures to further the Company’s long-term profitable growth opportunities. Looking beyond the current
environment, management believes the lighting and lighting-related industry will experience solid growth over
the next decade, particularly as energy and environmental concerns come to the forefront, and that the Company is
well-positioned to fully participate in the industry.

Accounting Standards Adopted in Fiscal 2010

In June 2009, the Financial Accounting Standards Board (“FASB”) issued SFAS No. 168, The FASB
Accounting Standards CodificationTM and the Hierarchy of Generally Accepted Accounting Principles — a
replacement of FASB Statement No. 162 (“SFAS 168”), which confirms that as of July 1, 2009, the FASB
Accounting Standards CodificationTM (“Codification”) is the single official source of authoritative, nongovern-
mental U.S. GAAP. All existing accounting standard documents are superseded, and all other accounting literature
not included in the Codification is considered nonauthoritative. SFAS 168 — which now resides in the Accounting
Standards Codification (“ASC”) Topic 105, Generally Accepted Accounting Principles (“ASC 105”), within the
Codification — was effective for interim and annual periods ending after September 15, 2009 and, therefore, was
adopted by the Company on November 30, 2009. The Company determined, however, that the standard did not have
an effect on the Company’s financial position, results of operations, or cash flows upon adoption.

In June 2009, the FASB issued Accounting Standards Update (“ASU”) No. 2009-1, Topic 105 — Generally
Accepted Accounting Principles — amendments based on — Statement of Financial Accounting Standards
No. 168 — The FASB Accounting Standards CodificationTM and the Hierarchy of Generally Accepted Accounting
Principles (“ASU 2009-1”), which amends the Codification for the issuance of SFAS 168. See discussion on
SFAS 168 above as adoption was concurrent with that standard.

In January 2010, the FASB issued ASU No. 2010-06, Fair Value Measurements and Disclosures (Topic 820) —
Improving Disclosures about Fair Value Measurements (“ASU 2010-06”). The updates to the Codification require new
disclosures around transfers into and out of Levels 1 and 2 in the fair value hierarchy and separate disclosures about
purchases, sales, issuances, and settlements related to Level 3 measurements. ASU 2010-06 is effective for interim and
annual reporting periods beginning after December 15, 2009 with early adoption permitted, except for the disclosures about
purchases, sales, issuances, and settlements in the rollforward of Level 3 activity. Those disclosures are effective for fiscal
years beginning after December 15, 2010 and for interim periods within those fiscal years with early adoption permitted.
The Company adopted the provisions of ASU 2010-06 effective March 1, 2010. The Company determined that the update
had no impact on its financial position, results of operations, or cash flows upon adoption.

30

In February 2010, the FASB issued ASU No. 2010-09, Subsequent Events (Topic 855) — Amendments to
Certain Recognition and Disclosure Requirements (“ASU 2010-09”). The amendments in this standard update
define a SEC filer within the Codification and eliminate the requirement for an SEC filer to disclose the date
through which subsequent events have been evaluated in order to remove potential conflicts with current SEC
guidance. The relevant provisions of ASU 2010-09 were effective upon the date of issuance of February 24, 2010,
and the Company adopted the amendments accordingly. As the update only pertained to disclosures, ASU 2010-09
had no impact on the Company’s financial position, results of operations, or cash flows upon adoption.

In December 2008, the FASB issued revisions to ASC Topic 715, Compensation — Retirement Benefits (“ASC
715”), that required additional disclosures around the fair value measurements of plan assets within an entity’s
defined benefit and other post-retirement plans. The revised guidance require disclosures around plan assets related
to: 1) investment allocation decisions, 2) major categories of plan assets, 3) inputs and valuation techniques,
4) effect of changes in value of Level 3 assets, and 5) concentrations of risk. The provisions of this standard were
effective for fiscal years ending after December 15, 2009, and were therefore adopted by the Company as of the
fiscal year ended August 31, 2010. As the revisions only pertained to disclosures, the adoption of these requirements
had no impact on the Company’s financial position, results of operations, or cash flows upon adoption.

In June 2008, FASB issued guidance within ASC Topic 260, Earnings Per Share (“ASC 260”), to clarify that
unvested share-based payment awards with a right to receive nonforfeitable dividends are participating securities.
The standard provides guidance on how to allocate earnings to participating securities and compute earnings per
share (“EPS”) using the two-class method. The provisions of this standard were effective for fiscal years beginning
after December 15, 2008, and interim periods within those fiscal years, and were therefore adopted by the Company
on September 1, 2009. The EPS amounts for previously reported periods have been adjusted due to retrospective
adoption of this standard. The Company’s diluted EPS from continuing operations for the years ended August 31,
2009 and 2008, under this guidance are $2.01 and $3.51, respectively, as compared to $2.05 and $3.57 previously
reported for these periods.

In December 2007, the FASB issued guidance within ASC Topic 805, Business Combinations (“ASC 805”),
which changes the accounting for business combinations through a requirement to recognize 100% of the fair values
of assets acquired, liabilities assumed, and noncontrolling interests in acquisitions of less than a 100% controlling
interest when the acquisition constitutes a change in control of the acquired entity. Other requirements include
capitalization of acquired in-process research and development assets, expensing, as incurred, acquisition-related
transaction costs and capitalizing restructuring charges as part of the acquisition only if requirements of ASC Topic
420, Exit or Disposal Obligations, are met. The standard was effective for business combination transactions for
which the acquisition date was on or after the beginning of the first annual reporting period beginning on or after
December 15, 2008 and was therefore adopted by the Company on September 1, 2009. See the Acquisitions
footnote of the Notes to Consolidated Financial Statements for the impact of business combinations under this
guidance on the Company’s financial position, results of operations, and cash flows.

In December 2007, the FASB issued guidance within ASC Topic 810, Consolidation (“ASC 810”), that
establishes the economic entity concept of consolidated financial statements, stating that holders of a residual
economic interest in an entity have an equity interest in the entity, even if the residual interest is related to only a
portion of the entity. Therefore, this standard requires a noncontrolling interest to be presented as a separate
component of equity. The standard also states that once control is obtained, a change in control that does not result in
a loss of control should be accounted for as an equity transaction. The statement requires that a change resulting in a
loss of control and deconsolidation is a significant event triggering gain or loss recognition and the establishment of
a new fair value basis in any remaining ownership interests. The standard was effective for fiscal years beginning on
or after December 15, 2008 and was therefore adopted by the Company on September 1, 2009. The implementation
of this guidance had no effect on the Company’s financial position, results of operations, or cash flows, as the
Company does not currently consolidate an entity with a noncontrolling interest.

Accounting Standards Yet to Be Adopted

In September 2009, the FASB issued ASU No. 2009-14, Software (Topic 985) — Certain Revenue Arrange-
ments That Include Software Elements (“ASU 2009-14”). ASU 2009-14 changes the accounting model for revenue

31

arrangements that include both tangible products and software elements to allow for alternatives when vendor-
specific objective evidence does not exist. Under this guidance, tangible products containing software components
and non-software components that function together to deliver the tangible product’s essential functionality and
hardware components of a tangible product containing software components are excluded from the software
revenue guidance in Subtopic 985-605, Software-Revenue Recognition; thus, these arrangements are excluded from
this update. ASU 2009-14 is effective prospectively for revenue arrangements entered into or materially modified in
fiscal years beginning on or after June 15, 2010 with early adoption permitted. ASU 2009-14 is therefore effective
for the Company no later than the beginning of fiscal 2011. The Company is currently in the process of determining
the impact, if any, of adoption of the provisions of ASU 2009-14.

In September 2009, the FASB issued ASU No. 2009-13, Revenue Recognition (Topic 605) — Multiple-
Deliverable Revenue Arrangements (“ASU 2009-13”). ASU 2009-13 addresses the accounting for multiple-
deliverable arrangements to enable vendors to account for products or services (“deliverables”) separately rather
than as a combined unit. Specifically, this guidance amends the criteria in Subtopic 605-25, Revenue Recognition-
Multiple-Element Arrangements, of the Codification for separating consideration in multiple-deliverable arrange-
ments. A selling price hierarchy is established for determining the selling price of a deliverable, which is based on:
(a) vendor-specific objective evidence; (b) third-party evidence; or (c) company-specific estimates. This guidance
also eliminates the residual method of allocation and requires that arrangement consideration be allocated at the
inception of the arrangement to all deliverables using the relative selling price method. Additional disclosures
related to a vendor’s multiple-deliverable revenue arrangements are also required by this update. ASU 2009-13 is
effective prospectively for revenue arrangements entered into, or materially modified, in fiscal years beginning on
or after June 15, 2010 with early adoption permitted. ASU 2009-13 is therefore effective for the Company no later
than the beginning of fiscal 2011. The Company is currently in the process of determining the impact, if any, of
adoption of the provisions of ASU 2009-13.

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 the Company’s 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 and reported amounts of revenue and expense during the reporting period. On an ongoing basis,
management evaluates its estimates and judgments, including those related to inventory valuation; depreciation,
amortization and the recoverability of long-lived assets, including goodwill and intangible assets; share-based
compensation expense; medical, product warranty, and other reserves; litigation; and environmental matters.
Management bases its estimates and judgments on its substantial historical experience and other relevant factors,
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. Management discusses the
development of accounting estimates with the Company’s Audit Committee. See the Summary of Significant
Accounting Policies footnote of the Notes to Consolidated Financial Statements for a summary of the accounting
policies of Acuity Brands.

The management of Acuity Brands believes the following represent the Company’s critical accounting

estimates:

Inventories

Inventories include materials, direct labor, and related manufacturing overhead, and are stated at the lower of
cost (on a first-in, first-out or average-cost basis) or market. Management reviews inventory quantities on hand and
records a provision for excess or obsolete inventory primarily based on estimated future demand and current market
conditions. A significant change in customer demand or market conditions could render certain inventory obsolete
and thus could have a material adverse impact on the Company’s operating results in the period the change occurs.

32

Goodwill and Indefinite Lived Intangible Assets

The Company reviews 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 long-lived asset is below its carrying value. All other long-lived and intangible
assets are reviewed for impairment whenever events or circumstances indicate that the carrying amount of the asset
may not be recoverable. An impairment loss for goodwill and indefinite lived intangibles 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 other appropriate fair value methods. 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, projected future net sales, operating results,
and cash flow.

Although management currently believes 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 flow
and/or changes in the discount rate or theoretical royalty rate could cause these assets to be deemed impaired. If this
were to occur, the Company would be required to charge to earnings the write-down in value of such assets, which
could have a material adverse effect on the Company’s results of operations and financial position, but not its cash
flows from operations.

Goodwill

The Company is comprised of one reporting unit with a goodwill balance of $515.6. In determining the fair
value of the Company’s reporting unit, the Company uses a discounted cash flow analysis, which requires
significant assumptions about discount rates as well as short and long-term growth (or decline) rates, in accordance
with U.S. GAAP. The Company utilized an estimated discount rate of 10% as of June 1, 2010, based on the Capital
Asset Pricing Model, which considers the updated risk-free interest rate, beta, market risk premium, and entity
specific size premium. Short-term growth (or decline) rates are based on management’s forecasted financial results,
which consider key business drivers such as specific revenue growth initiatives, market share changes, growth (or
decline) in non-residential and residential construction markets, and general economic factors such as credit
availability and interest rates. The Company calculates the discounted cash flows using a 10-year period with a
terminal value and compares this calculation to the discounted cash flows generated over a 40-year period to ensure
reasonableness. The long-term growth rate used in determining terminal value is estimated at 3% for the Company
and is primarily based on the Company’s understanding of projections for expected long-term growth in non-
residential construction, the Company’s key market.

During fiscal 2010, the Company performed an evaluation of the fair value of goodwill. The goodwill analysis
did not result in an impairment charge, as the estimated fair value of the reporting unit continues to exceed the
carrying value by such a significant amount that any reasonably likely change in the assumptions used in the
analysis, including revenue growth rates and the discount rate, would not cause the carrying value to exceed the
estimated fair value for the reporting unit as determined under the step one goodwill impairment analysis.

Indefinite Lived Intangible Assets

The Company’s indefinite lived intangible assets consist of five unamortized trade names with an aggregate
carrying value of approximately $96.1. Management utilizes significant assumptions to estimate the fair value of
these unamortized trade names using a fair value model based on discounted future cash flows in accordance with
U.S. GAAP. Future cash flows associated with each of the Company’s unamortized trade names are calculated by
applying a theoretical royalty rate a willing third party would pay for use of the particular trade name to estimated
future net sales. The present value of the resulting after-tax cash flow is management’s current estimate of the fair
value of the trade names. This fair value model requires management to make several significant assumptions,
including estimated future net sales, the royalty rate, and the discount rate.

Future net sales and short-term growth (or decline) rates are estimated for each particular trade name based on
management’s forecasted financial results which consider key business drivers such as specific revenue growth
initiatives, market share changes, expected growth (or decline) in non-residential and residential construction

33

markets, and general economic factors such as credit availability and interest rates. The long-term growth rate used
in determining terminal value is estimated at 3% for the Company and is primarily based on the Company’s
understanding of projections for expected long-term growth in non-residential construction, the Company’s key
market. The theoretical royalty rate is estimated using a factor of operating profit margins and management’s
assumptions regarding the amount a willing third party would pay to use the particular trade name. Differences
between expected and actual results can result in significantly different valuations. If future operating results are
unfavorable compared with forecasted amounts, the Company may be required to reduce the theoretical royalty rate
used in the fair value model. A reduction in the theoretical royalty rate would result in lower expected future after-
tax cash flow in the valuation model. With the exception of the LC&D trade names, the Company utilized a range of
estimated discount rates between 10 and 14% as of June 1, 2010, based on the Capital Asset Pricing Model, which
considers the updated risk-free interest rate, beta, market risk premium, and entity specific size premium.

During fiscal 2010, the Company performed an evaluation of the fair value of its five unamortized trade names.
The Company’s expected revenues are based on the Company’s fiscal 2011 plan and recent lighting market growth
or decline estimates for fiscal 2011 through 2015. The Company also included revenue growth estimates based on
current initiatives expected to help the Company improve performance. During fiscal 2010, estimated theoretical
royalty rates ranged between 1% and 4%. The indefinite lived intangible asset analysis did not result in an
impairment charge, as the fair values exceeded the carrying values for each trade name by a significant amount,
except for the Mark Lighting and LC&D trade names, which had fair values that exceeded each of its carrying
values of $8.6 and $6.9, respectively, by approximately 31.4% and 4.5%, respectively. The estimated fair values of
the indefinite lived intangible assets, other than the Mark Lighting and LC&D trade names, exceed the carrying
values by such a significant amount that any reasonably likely change in the assumptions used in the analyses,
including revenue growth rates and the discount rate, would not cause the carrying values to exceed the estimated
fair values as determined by the fair value analyses. The Company determined that any estimated potential
impairment related to the Mark Lighting or LC&D trade names based on reasonable changes in the assumptions that
would be less likely to occur would not be material to the Company’s financial results, trend of earnings, or financial
position.

Self-Insurance

The Company self-insures, up to certain limits, traditional risks including workers’ compensation, compre-
hensive general liability, and auto liability. The Company’s self-insured retention for each claim involving workers’
compensation, comprehensive general liability (including product liability claims), and auto liability is limited to
$0.5 per occurrence of such claims. A provision for claims under this self-insured program, based on the Company’s
estimate of the aggregate liability for claims incurred, is revised and recorded annually. The estimate is derived from
both internal and external sources including but not limited to the Company’s independent actuary. The Company is
also self-insured up to certain limits for certain other insurable risks, primarily physical loss to property ($0.5 per
occurrence) and business interruptions resulting from such loss lasting two days or more in duration. Insurance
coverage is maintained for catastrophic property and casualty exposures as well as those risks required to be insured
by law or contract. The Company is fully self-insured for certain other types of liabilities, including environmental,
product recall, and patent infringement. The actuarial estimates calculated are subject to uncertainty from various
sources, including, among others, changes in claim reporting patterns, claim settlement patterns, judicial decisions,
legislation, and economic conditions. Although the Company believes that the actuarial estimates are reasonable,
significant differences related to the items noted above could materially affect the Company’s self-insurance
obligations, future expense and cash flow.

The Company is also self-insured for the majority of its medical benefit plans with individual claims limited to
$0.3. The Company estimates its aggregate liability for claims incurred by applying a lag factor to the Company’s
historical claims and administrative cost experience. The appropriateness of the Company’s lag factor is evaluated
and revised, if necessary, annually. Although management believes that the current estimates are reasonable,
significant differences related to claim reporting patterns, plan designs, legislation, and general economic con-
ditions could materially affect the Company’s medical benefit plan liabilities, future expense and cash flow.

34

Income Taxes

The Company uses certain assumptions and estimates in determining the income taxes payable or refundable
for the current year, income tax expense, and deferred income tax liabilities and assets, which represent temporary
and permanent differences between amounts within the financial statements and the income tax basis. ASC 740,
Income Taxes (“ASC 740”), requires the evaluation and testing of the recoverability of deferred tax assets. Deferred
tax assets are reduced by a valuation allowance if, based on the relevant factors, it is more likely than not that all or
some portion of the deferred tax assets will not be realized. Reasonable judgment and estimates are required in
determining whether a valuation allowance is necessary and, if so, the amount of such valuation allowance. In
evaluating the need for a valuation allowance, the Company considers a number of factors, including, but not
limited to: the nature and character of the deferred tax assets and liabilities; taxable income in prior carryback years;
future reversals of existing temporary differences; and the length of time carryovers can be utilized.

In light of the multiple tax jurisdictions in which the Company operates, the Company’s tax returns are subject
to routine audit by the Internal Revenue Service (“IRS”) and other taxation authorities. These audits at times
produce uncertainty regarding particular tax positions taken in the year(s) of review. The Company records
uncertain tax positions as prescribed by ASC 740, which requires recognition at the time when it is more likely than
not that the position in question will be upheld. Although management believes that the judgment and estimates
involved are reasonable and that the necessary provisions have been recorded, changes in circumstances or
unexpected events could adversely affect the Company’s financial position, results from operations, and cash flows.

Retirement Benefits

The Company sponsors domestic and international defined benefit pension plans and domestic defined
contribution plans and other postretirement plans. Assumptions are used to determine the estimated fair value of
plan assets, the actuarial value of plan liabilities, and the current and projected costs for these employee benefit
plans and include, among other factors, estimated discount rates, expected returns on the pension fund assets,
estimated mortality rates, and the rates of increase in employee compensation levels. These assumptions are
determined based on Company and market data and are evaluated annually as of the plans’ measurement date. See
the Pensions and Profit Sharing Plans footnote of the Notes to Consolidated Financial Statements for further
information on the Company’s plans.

Share-Based Compensation Expense

The Company recognizes compensation cost relating to share-based payment transactions in the financial
statements based on the estimated fair value of the equity or liability instrument issued. The Company accounts for
stock options, restricted shares, and share units representing certain deferrals into the Director Deferred Com-
pensation Plan or the Supplemental Deferred Savings Plan (both of which are discussed further in the Share-Based
Payments footnote of the Notes to Consolidated Financial Statements) using the modified prospective method.
Under the modified prospective method, share-based expense recognized includes: (a) share-based expense for all
awards granted prior to, but not yet vested as of September 1, 2005, based on the grant date fair value estimated
under the previous guidance, and (b) share-based expense for all awards granted subsequent to September 1, 2005,
based on the grant-date fair value estimated under the current provisions of ASC Topic 718, Compensation — Stock
Compensation (“ASC 718”). The Company recorded $11.8, $13.0, and $12.0 of share-based expense in continuing
operations for the years ended August 31, 2010, 2009, and 2008, respectively.

The Company employs the Black-Scholes model in deriving the fair value estimates of share-based awards and
records estimates of forfeitures of share-based awards at the time of grant, which are revised in subsequent periods if
actual forfeitures differ from initial estimates. Therefore, the expense related to share-based payments recognized in
fiscal 2010, 2009, and 2008 has been reduced for estimated forfeitures. As of August 31, 2010, there was $16.8 of
total unrecognized compensation cost related to unvested restricted stock. That cost is expected to be recognized
over a weighted-average period of 2.2 years. As of August 31, 2010, there was $2.5 of total unrecognized
compensation cost related to unvested options. That cost is expected to be recognized over a weighted-average
period of 1.6 years. 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

35

recorded in the current period. See the Summary of Significant Accounting Policies and Share-Based Payments
footnotes of the Notes to Consolidated Financial Statements for more information regarding the assumptions used
in estimating the fair value of stock options.

Product Warranty and Recall Costs

The Company records an allowance for the estimated amount of future warranty costs when the related revenue
is recognized, primarily based on historical experience of identified warranty claims. Excluding costs related to
recalls due to faulty components provided by third parties, historical warranty costs have been within expectations.
However, there can be no assurance that future warranty costs will not exceed historical amounts. If actual future
warranty costs exceed historical amounts, additional allowances may be required, which could have a material
adverse impact on the Company’s operating results and cash flow in future periods.

Litigation

The Company recognizes expense for legal claims when payments associated with the claims become
probable and can be reasonably estimated. Due to the difficulty in estimating costs of resolving legal claims, actual
costs may be substantially higher or lower than the amounts reserved.

Environmental Matters

The Company recognizes expense for known environmental claims when payments associated with the claims
become probable and the costs can be reasonably estimated. The actual cost of resolving environmental issues may
be higher or lower than that reserved primarily due to difficulty in estimating such costs and potential changes in the
status of government regulations. The Company is self-insured for most environmental matters.

those expressed in the Company’s forward-looking statements are discussed in Part I, “Item 1a. Risk Factors” of
this Annual Report on Form 10-K, and are specifically incorporated herein by reference.

36

Item 7a. Quantitative and Qualitative Disclosures about Market Risk

General. The Company is exposed to worldwide market risks that may impact the Consolidated Balance
Sheets, Consolidated Statements of Income, and Consolidated Statements of Cash Flows due primarily to changing
interest and foreign exchange rates as well as volatility in commodity prices. The following discussion provides
additional information regarding the market risks of Acuity Brands.

Interest Rates.

Interest rate fluctuations expose the variable-rate debt of the Company to changes in interest
expense and cash flows. At August 31, 2010, the variable-rate debt of the Company was solely comprised of the $4.0
long-term industrial revenue bond. A 10% increase in market interest rates at August 31, 2010, would have resulted
in a de minimus amount of additional annual after-tax interest expense. A fluctuation in interest rates would not
affect interest expense or cash flows related to the Company’s fixed-rate debt which includes the $350.0 publicly-
traded fixed-rate notes. A 10% increase in market interest rates at August 31, 2010, would have decreased the
estimated fair value of these debt obligations by approximately $12.7. See the Debt and Lines of Credit footnote of
the Notes to Consolidated Financial Statements, contained in this Form 10-K, for additional information regarding
the Company’s debt.

Foreign Exchange Rates. The majority of net sales, expense, and capital purchases of the Company are
transacted in U.S. dollars. However, exposure with respect to foreign exchange rate fluctuation exists due to the
Company’s operations in Canada, where a significant portion of products sold are sourced from the United States. A
hypothetical decline in the Canadian dollar of 10% would negatively impact operating profit by approximately $7.0.
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% increase in the Mexican peso would negatively impact operating
profits by approximately $3.7. The impact of these hypothetical currency fluctuations has been calculated in
isolation from any response the Company would undertake to address such exchange rate changes in the Company’s
foreign markets.

Commodity Prices. The Company utilizes a variety of raw materials and components in its production
process including petroleum-based products, steel, and aluminum. In fiscal 2010, the Company purchased
approximately 119,000 tons of steel and aluminum. The Company estimates that less than 10% of the raw
materials purchased are petroleum-based and that approximately 3.5 million gallons of diesel fuel was consumed in
fiscal 2010. Failure to effectively manage future increases in the costs of these items could adversely affect the
ability to maintain or increase operating margins.

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, 2010. 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. Based on this assessment, management believes that, as of August 31, 2010, the Company’s
internal control over financial reporting is effective.

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 29, 2010 appears on page 41 of this
Form 10-K.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Stockholders
Acuity Brands, Inc.

We have audited the accompanying consolidated balance sheets of Acuity Brands, Inc. as of August 31, 2010
and 2009, and the related consolidated statements of income, stockholders’ equity and comprehensive income, and
cash flows for each of the three years in the period ended August 31, 2010. Our audits also included the financial
statement schedule listed in the Index at Item 15(a). These consolidated financial statements and schedule are the
responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated
financial statements and schedule based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board
(United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about
whether the financial statements are free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the
accounting principles used and significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the
consolidated financial position of Acuity Brands, Inc. at August 31, 2010 and 2009, and the consolidated results
of its operations and its cash flows for each of the three years in the period ended August 31, 2010, in conformity
with U.S. generally accepted accounting principles. Also, in our opinion, the related financial statement schedule,
when considered in relation to the basic financial statements taken as a whole, presents fairly in all material respects
the information set forth therein.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board
(United States), Acuity Brands, Inc.’s internal control over financial reporting as of August 31, 2010, based on
criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organiza-
tions of the Treadway Commission and our report dated October 29, 2010 expressed an unqualified opinion thereon.

Report of Independent Registered Public Accounting Firm on Internal Control
Over Financial Reporting

The Board of Directors and Stockholders
Acuity Brands, Inc.

We have audited Acuity Brands, Inc.’s internal control over financial reporting as of August 31, 2010, based on
criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Orga-
nizations of the Treadway Commission (the COSO criteria). Acuity Brands, Inc.’s management is responsible for
maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal
control over financial reporting included in the accompanying Management’s Report on Internal Control Over
Financial Reporting. Our responsibility is to express an opinion on the company’s internal control over financial
reporting based on our audit.

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

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

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

In our opinion, Acuity Brands, Inc. maintained, in all material respects, effective internal control over financial

reporting as of August 31, 2010, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board
(United States), the consolidated balance sheets of Acuity Brands, Inc. as of August 31, 2010 and 2009, and the
related consolidated statements of income, stockholders’ equity and comprehensive income, and cash flows for
each of the three years in the period ended August 31, 2010 of Acuity Brands, Inc. and our report dated October 29,
2010 expressed an unqualified opinion thereon.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(Amounts in millions, except per-share data and as indicated)

1. Description of Business and Basis of Presentation

Acuity Brands, Inc. (“Acuity Brands”) is the parent company of Acuity Brands Lighting, Inc. (“ABL”),
formerly known as Acuity Lighting Group, Inc., and other subsidiaries (collectively referred to herein as “the
Company”). The Company designs, produces, and distributes a broad array of indoor and outdoor lighting fixtures
and related products, including lighting controls, and services for commercial and institutional, industrial,
infrastructure, and residential applications for various markets throughout North America and select international
markets. The Company has one operating segment.

On July 26, 2010, the Company acquired the remaining outstanding capital stock of Renaissance Lighting, Inc.
(“Renaissance”), a privately-held, pioneering innovator of solid-state light-emitting diode (“LED”) architectural
lighting. Renaissance, based in Herndon, Virginia, offered a full range of LED-based specification-grade down-
lighting luminaires and has developed an extensive intellectual property portfolio related to advanced LED optical
solutions and technologies. Previously, the Company entered into a strategic partnership with Renaissance, which
included a noncontrolling interest in Renaissance and a license to Renaissance’s intellectual property estate. The
operating results of Renaissance have been included in the Company’s consolidated financial statements since the
date of acquisition.

On April 20, 2009, the Company acquired 100% of the outstanding capital stock of Sensor Switch, Inc.
(“Sensor Switch”), an industry-leading developer and manufacturer of lighting controls and energy management
systems. Sensor Switch, based in Wallingford, Connecticut, offered a wide-breadth of products and solutions that
substantially reduce energy consumption, including occupancy sensors, photocontrols, and distributed lighting
control devices. The operating results of Sensor Switch have been included in the Company’s consolidated financial
statements since the date of acquisition.

On December 31, 2008, the Company acquired for cash and stock substantially all the assets and assumed
certain liabilities of Lighting Controls & Design (“LC&D”). Located in Glendale, California, LC&D is a
manufacturer of comprehensive digital lighting controls and software that offered a breadth of products, ranging
from dimming and building interfaces to digital thermostats, all within a single, scalable system. The operating
results of LC&D have been included in the Company’s consolidated financial statements since the date of
acquisition.

Acuity Brands completed the spin-off of its specialty products business (the “Spin-off”), Zep Inc. (“Zep”) on
October 31, 2007, by distributing all of the shares of Zep common stock, par value $.01 per share, to the Company’s
stockholders of record as of October 17, 2007. The Company’s stockholders received one Zep share, together with
an associated preferred stock purchase right, for every two shares of the Company’s common stock they owned.
Stockholders received cash in lieu of fractional shares for amounts less than one full Zep share.

As a result of the Spin-off, the Company’s financial statements have been prepared with the net assets, results
of operations, and cash flows of the specialty products business presented as discontinued operations. All historical
statements have been restated to conform to this presentation. Refer to the Discontinued Operations footnote.

The Consolidated Financial Statements have been prepared by the Company in accordance with U.S. generally
accepted accounting principles (“U.S. GAAP”) and present the financial position, results of operations, and cash
flows of Acuity Brands and its wholly-owned subsidiaries. References made to years are for fiscal year periods.

In conjunction with the Spin-off, Acuity Brands and Zep entered into various agreements that address the
allocation of assets and liabilities between them and that define their relationship after the separation, including a
distribution agreement, a tax disaffiliation agreement, an employee benefits agreement, and a transition services
agreement. The income from discontinued operations relates to the revision of estimates during the second quarter
of fiscal 2010 of certain legal reserves established at the time of the Spin-off. As it was with the original reserve, the
income from discontinued operations had no income tax effect. Information regarding guarantees and indemnities
related to the Spin-off are included in the Commitments and Contingencies footnote.

3. Significant Accounting Policies

Principles of Consolidation

The Consolidated Financial Statements include the accounts of Acuity Brands and its wholly-owned

subsidiaries after elimination of significant intercompany transactions and accounts.

Revenue Recognition

The Company records revenue when the following criteria are met: persuasive evidence of an arrangement
exists, delivery has occurred, the Company’s price to the customer is fixed and determinable, and collectability is
reasonably assured. Delivery is not considered to have occurred until the customer assumes the risks and rewards of
ownership. Customers take delivery at the time of shipment for terms designated free on board shipping point. For
sales designated free on board destination, customers take delivery when the product is delivered to the customer’s
delivery site. Provisions for certain rebates, sales incentives, product returns, and discounts to customers are
recorded in the same period the related revenue is recorded. The Company also maintains one-time or on-going
marketing and trade-promotion programs with certain customers that require the Company to estimate and accrue
the expected costs of such programs. These arrangements include cooperative marketing programs, merchandising
of the Company’s products, and introductory marketing funds for new products and other trade-promotion activities
conducted by the customer. Costs associated with these programs are reflected within the Company’s Consolidated
Statements of Income in accordance with the Accounting Standards Codification (“ASC”) Topic 605, Revenue
Recognition (“ASC 605”), which in most instances requires such costs be recorded as a reduction of revenue.

The Company provides for limited product return rights to certain distributors and customers primarily for
slow moving or damaged items subject to certain defined criteria. The Company monitors product returns and, at the
time revenue is recognized, records a provision for the estimated amount of future returns based primarily on
historical experience and specific notification of pending returns. Although historical product returns generally
have been within expectations, there can be no assurance that future product returns will not exceed historical
amounts. A significant increase in product returns could have a material impact on the Company’s operating results
in future periods.

47

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

ACUITY BRANDS, INC.

For the Company’s turnkey labor renovation services, revenue is earned on installation services and lighting
fixtures. Revenue is recognized for the service and fixtures in the period that the installation of the fixtures is
completed.

Use of Estimates

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

Cash and Cash Equivalents

Cash in excess of daily requirements is invested in time deposits and marketable securities and is included in
the accompanying balance sheets at fair value. Acuity Brands considers time deposits and marketable securities
with an original maturity of three months or less when purchased to be cash equivalents.

Accounts Receivable

The Company records accounts receivable at net realizable value. This value includes an allowance for
estimated uncollectible accounts to reflect losses anticipated on accounts receivable balances. The allowance is
based on historical write-offs, an analysis of past due accounts based on the contractual terms of the receivables, and
economic status of customers, if known. Management believes that the allowance is sufficient to cover uncollectible
amounts; however, there can be no assurance that unanticipated future business conditions of customers will not
have a negative impact on the Company’s results of operations.

Concentrations of Credit Risk

Concentrations of credit risk with respect to receivables, which are typically unsecured, are generally limited
due to the wide variety of customers and markets using the Company’s products, as well as their dispersion across
many different geographic areas. Receivables from The Home Depot were approximately $34.0 and $30.2 at
August 31, 2010 and 2009, respectively. No other single customer accounted for more than 10% of consolidated
receivables at August 31, 2010. Additionally, net sales to The Home Depot accounted for approximately 11% of net
sales of the Company in fiscal 2010, 2009, and 2008.

Reclassifications

Certain prior-period amounts have been reclassified to conform to current year presentation.

Subsequent Events

The Company has evaluated, for recognition and disclosure, subsequent events for occurrences and trans-

actions after the date of the consolidated financial statements for the year ended August 31, 2010.

Through multiple acquisitions, the Company acquired intangible assets consisting primarily of trademarks
associated with specific products with finite lives, definite-lived distribution networks, patented technology, non-
compete agreements, and customer relationships, which are amortized over their estimated useful lives. Indefinite
lived intangible assets consist of trade names that are expected to generate cash flows indefinitely. Significant
estimates and assumptions were used to determine the fair value of these acquired intangible assets, including
estimated future net sales, royalty rates, and discount rates. The current year increases in the gross carrying amounts
for the acquired intangible assets were due to the Renaissance acquisition (refer to the Acquisitions footnote). With
regards to the Renaissance acquisition, the weighted average useful life of the intangible assets with finite lives
acquired by the Company was estimated at 7.5 years, which consisted primarily of intangible assets related to
patented technology and in-process research and development.

The Company recorded amortization expense of $7.1, $5.4, and $3.7 related to intangible assets with finite
lives during fiscal 2010, 2009, and 2008, respectively. Amortization expense is generally recorded on a straight-line
basis and is expected to be approximately $8.2 in fiscal 2011, $7.3 in fiscal 2012, $6.5 in fiscal 2013, $6.4 in fiscal
2014, and $6.2 in fiscal 2015. The decrease in expected amortization expense in fiscal 2012 is due to the completion
of the amortization during fiscal 2011 of certain acquired patented technology assets. The decrease in fiscal 2013 is
due to the completion of the amortization during fiscal 2012 of certain acquired customer relationships. Included in
these amounts are the impact of incremental amortization expense for the December 31, 2008 acquisition of

49

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

substantially all the assets and the assumption of certain liabilities of LC&D, the April 20, 2009 acquisition of
Sensor Switch, and the July 26, 2010 acquisition of Renaissance.

The changes in the carrying amount of goodwill during the year are summarized as follows:

The Company tests indefinite lived intangible assets and goodwill for impairment on an annual basis or more
frequently as facts and circumstances change, as required by ASC Topic 350, Intangibles — Goodwill and Other
(“ASC 350”). The goodwill impairment test has two steps. The first step identifies potential impairments by
comparing the fair value of a reporting unit with its carrying value, including goodwill. The fair values are
determined based on a combination of valuation techniques including the expected present value of future cash
flows, a market multiple approach, and a comparable transaction approach. If the fair value of a reporting unit
exceeds the carrying value, goodwill is not impaired and the second step is not necessary. If the carrying value of a
reporting unit exceeds the fair value, the second step calculates the possible impairment loss by comparing the
implied fair value of goodwill with the carrying value. If the implied fair value of the goodwill is less than the
carrying value, an impairment charge is recorded. The impairment test for unamortized trade names consists of
comparing the fair value of the asset with its carrying value. The Company estimates the fair value of these
unamortized trade names using a fair value model based on discounted future cash flows. If the carrying amount
exceeds the measured fair value, an impairment loss would be recorded in the amount of the excess. Significant
assumptions, including estimated future net sales, royalty rates, and discount rates, were used in the determination
of estimated fair value for both goodwill and indefinite lived intangible assets. Neither of the analyses resulted in an
impairment charge during fiscal 2010, 2009, or 2008.

(1) Long-term investments — The Company maintains certain investments that generate returns that offset changes
in certain liabilities related to deferred compensation arrangements. The investments primarily consist of
marketable equity securities and fixed income securities, are stated at fair value, and are classified as trading in
accordance with ASC Topic 320, Investments — Debt and Equity Securities. Realized and unrealized gains and

50

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

ACUITY BRANDS, INC.

losses are included in the Consolidated Statements of Income and generally offset the change in the deferred
compensation liability. The decrease since August 31, 2009 was due primarily to payments made to certain
participants in these deferred compensation arrangements.

(2) Investments in nonconsolidating affiliates — During fiscal 2009, the Company acquired an equity investment in
Renaissance. This strategic investment represented less than a 20% ownership interest, and the Company did
not maintain power over or control of the entity. In July 2010, the Company acquired the remaining outstanding
capital stock and, thus, subsequent control of Renaissance. See the Acquisitions footnote for details.

As of August 31, 2010, the Company reported assets held for sale of $3.4, which were comprised of $0.4 in
short-term assets and $3.0 in long-term assets. The assets represent two properties that the Company intends to sell
to third parties within one year, or, in certain circumstances, beyond one year as allowed by ASC Topic 360,
Property, Plant, and Equipment (“ASC 360”), as the facilities have been deemed unnecessary to current operations.

(1) Deferred compensation and long-term postretirement benefits other than pensions — The Company main-
tains several non-qualified retirement plans for the benefit of eligible employees, primarily deferred com-
pensation plans. The deferred compensation plans provide for elective deferrals of an eligible employee’s
compensation and, in some cases, matching contributions by the Company. In addition, one plan provides for an
automatic contribution by the Company of 3% of an eligible employee’s compensation. The Company
maintains certain long-term investments that offset a portion of the deferred compensation liability. The
Company maintains life insurance policies on certain current and former officers and other key employees as a
means of satisfying a portion of these obligations.

(2) Postemployment benefit obligation — ASC Topic 712, Compensation — Nonretirement Postemployment Ben-
efits, requires the accrual of the estimated cost of benefits provided by an employer to former or inactive
employees after employment but before retirement. The Company’s accrual relates primarily to the liability for
life insurance coverage for certain eligible employees.

(3) See the Income Taxes footnote for more information.

Shipping and Handling Fees and Costs

The Company includes shipping and handling fees billed to customers in Net Sales. Shipping and handling
costs associated with inbound freight and freight between manufacturing facilities and distribution centers are
generally recorded in Cost of Products Sold. Other shipping and handling costs are included in Selling, Distribution,
and Administrative Expenses and totaled $88.4, $86.8, and $84.6 in fiscal 2010, 2009, and 2008, respectively.

51

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

ACUITY BRANDS, INC.

Share-Based Compensation

The Company recognizes compensation cost relating to share-based payment transactions in the financial
statements based on the estimated fair value of the equity or liability instrument issued. The Company accounts for
stock options, restricted shares, and share units representing certain deferrals into the Director Deferred Com-
pensation Plan or the Supplemental Deferred Savings Plan (both of which are discussed further in the Share-Based
Payments footnote) using the modified prospective method. Under the modified prospective method, share-based
expense recognized includes: (a) share-based expense for all awards granted prior to, but not yet vested as of
September 1, 2005, based on the grant date fair value estimated under the previous guidance, and (b) share-based
expense for all awards granted subsequent to September 1, 2005, based on the grant-date fair value estimated under
the current provisions of ASC Topic 718, Compensation — Stock Compensation (“ASC 718”).

Share-based expense includes expense related to restricted stock and options issued, as well as share units
deferred into either the Director Deferred Compensation Plan or the Supplemental Deferred Savings Plan. The
Company recorded $11.8, $13.0, and $12.0 of share-based expense in continuing operations for the years ending
August 31, 2010, 2009, and 2008, respectively. The total income tax benefit recognized in continuing operations for
share-based compensation arrangements was $4.2, $4.3, and $4.7 for the years ended August 31, 2010, 2009, and
2008, respectively. The Company accounts for any awards with graded vesting on a straight-line basis. Additionally,
forfeitures of share-based awards are estimated based on historical experience and recorded at the time of grant,
which are revised in subsequent periods if actual forfeitures differ from initial estimates. The Company did not
capitalize any expense related to share-based payments and has recorded share-based expense, net of estimated
forfeitures, in Selling, Distribution, and Administrative Expenses.

Excess tax benefits of $2.8, $0.4, and $5.0 related to share-based compensation were included in financing

activities in the Company’s Statements of Cash Flows for fiscal 2010, 2009, and 2008, respectively.

See the Share-Based Payments footnote for more information.

Depreciation

For financial reporting purposes, depreciation is determined principally on a straight-line basis using estimated
useful lives of plant and equipment (10 to 40 years for buildings and related improvements and 5 to 15 years for
machinery and equipment), while accelerated depreciation methods are used for income tax purposes. Leasehold
improvements are amortized over the shorter of the life of the lease or the estimated useful life of the improvement.
Depreciation expense amounted to $28.5, $29.6, and $29.7 during fiscal 2010, 2009, and 2008, respectively.

Research and Development

Research and development (“R&D”) expense, which are included in Selling, Distribution, and Administrative
Expenses in the Company’s Consolidated Statements of Income, are expensed as incurred. R&D expense amounted
to $28.0, $20.8, and $30.3 during fiscal 2010, 2009, and 2008, respectively.

Advertising

Advertising costs are expensed as incurred and are included within Selling, Distribution, and Administrative
Expenses in the Company’s Consolidated Statements of Income. These costs totaled $12.0, $8.7, and $7.6 during
fiscal 2010, 2009, and 2008, respectively.

Service Arrangements with Customers

The Company maintains a service program with one of its retail customers that affords the Company certain in-
store benefits, including lighting display maintenance. Costs associated with this program totaled $4.9, $4.8, and

52

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

ACUITY BRANDS, INC.

$5.1 in fiscal 2010, 2009, and 2008, respectively. These costs have been included within the Selling, Distribution,
and Administrative Expenses line item of the Company’s Consolidated Statements of Income.

Interest Expense, Net

Interest expense, net, is comprised primarily of interest expense on long-term debt, revolving credit facility
borrowings, and loans collateralized by assets related to the company-owned life insurance program, partially offset
by interest income on cash and cash equivalents.

The following table summarizes the components of interest expense, net:

Foreign Currency Translation

The functional currency for the foreign operations of the Company is the local currency. The translation of
foreign currencies into U.S. dollars is performed for balance sheet accounts using exchange rates in effect at the
balance sheet dates and for revenue and expense accounts using a weighted average exchange rate each month
during the year. The gains or losses resulting from the balance sheet translation are included in Comprehensive
Income in the Consolidated Statements of Stockholders’ Equity and Comprehensive Income and are excluded from
net income.

Gains or losses relating to foreign currency items are included in Miscellaneous expense (income), net, in the
Consolidated Statements of Income and consisted of income of $0.7 and $2.1, in fiscal 2010 and 2009, respectively,
and expense of $2.3 in fiscal 2008.

Miscellaneous Expense (Income), Net

Miscellaneous expense (income), net, is composed primarily of gains or losses on foreign currency items and

other non-operating items.

Income Taxes

The Company is taxed at regular corporate rates after adjusting income reported for financial statement
purposes for certain items that are treated differently for income tax purposes. Deferred income tax expenses
(benefits) result from changes during the year in cumulative temporary differences between the tax basis and book
basis of assets and liabilities.

4. New Accounting Pronouncements

Accounting Standards Adopted in Fiscal 2010

In June 2009, the Financial Accounting Standards Board (“FASB”) issued SFAS No. 168, The FASB
Accounting Standards CodificationTM and the Hierarchy of Generally Accepted Accounting Principles — a
replacement of FASB Statement No. 162 (“SFAS 168”), which confirms that as of July 1, 2009, the FASB
Accounting Standards CodificationTM (“Codification”)
source of authoritative,

the single official

is

53

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

ACUITY BRANDS, INC.

nongovernmental U.S. GAAP. All existing accounting standard documents are superseded, and all other accounting
literature not included in the Codification is considered nonauthoritative. SFAS 168 — which now resides in the
ASC Topic 105, Generally Accepted Accounting Principles (“ASC 105”), within the Codification — was effective
for interim and annual periods ending after September 15, 2009 and, therefore, was adopted by the Company on
November 30, 2009. The Company determined, however, that the standard did not have an effect on the Company’s
financial position, results of operations, or cash flows upon adoption.

In June 2009, the FASB issued Accounting Standards Update (“ASU”) No. 2009-1, Topic 105 — Generally
Accepted Accounting Principles — amendments based on — Statement of Financial Accounting Standards
No. 168 — The FASB Accounting Standards CodificationTM and the Hierarchy of Generally Accepted Accounting
Principles (“ASU 2009-1”), which amends the Codification for the issuance of SFAS 168. See discussion on
SFAS 168 above as adoption was concurrent with that standard.

In January 2010, the FASB issued ASU No. 2010-06, Fair Value Measurements and Disclosures (Topic 820) —
Improving Disclosures about Fair Value Measurements (“ASU 2010-06”). The updates to the Codification require
new disclosures around transfers into and out of Levels 1 and 2 in the fair value hierarchy and separate disclosures
about purchases, sales, issuances, and settlements related to Level 3 measurements. ASU 2010-06 is effective for
interim and annual reporting periods beginning after December 15, 2009 with early adoption permitted, except for
the disclosures about purchases, sales, issuances, and settlements in the rollforward of Level 3 activity. Those
disclosures are effective for fiscal years beginning after December 15, 2010 and for interim periods within those
fiscal years with early adoption permitted. The Company adopted the provisions of ASU 2010-06 effective March 1,
2010. The Company determined that the update had no impact on its financial position, results of operations, or cash
flows upon adoption.

In February 2010, the FASB issued ASU No. 2010-09, Subsequent Events (Topic 855) — Amendments to
Certain Recognition and Disclosure Requirements (“ASU 2010-09”). The amendments in this standard update
define a SEC filer within the Codification and eliminate the requirement for an SEC filer to disclose the date
through which subsequent events have been evaluated in order to remove potential conflicts with current SEC
guidance. The relevant provisions of ASU 2010-09 were effective upon the date of issuance of February 24, 2010,
and the Company adopted the amendments accordingly. As the update only pertained to disclosures, ASU 2010-09
had no impact on the Company’s financial position, results of operations, or cash flows upon adoption.

In December 2008, the FASB issued revisions to ASC Topic 715, Compensation — Retirement Benefits
(“ASC 715”), that required additional disclosures around the fair value measurements of plan assets within an
entity’s defined benefit and other post-retirement plans. The revised guidance require additional disclosures around
plan assets related to: 1) investment allocation decisions, 2) major categories of plan assets, 3) inputs and valuation
techniques, 4) effect of changes in value of Level 3 assets, and 5) concentrations of risk. The provisions of this
standard were effective for fiscal years ending after December 15, 2009, and were therefore adopted by the
Company as of the fiscal year ended August 31, 2010. As the revisions only pertained to disclosures, the adoption of
these requirements had no impact on the Company’s financial position, results of operations, or cash flows upon
adoption.

In June 2008, FASB issued guidance within ASC Topic 260, Earnings Per Share (“ASC 260”), to clarify that
unvested share-based payment awards with a right to receive nonforfeitable dividends are participating securities.
The standard provides guidance on how to allocate earnings to participating securities and compute earnings per
share (“EPS”) using the two-class method. The provisions of this standard were effective for fiscal years beginning
after December 15, 2008, and interim periods within those fiscal years, and were therefore adopted by the Company
on September 1, 2009. The EPS amounts for previously reported periods have been adjusted due to retrospective
adoption of this standard. The Company’s diluted EPS from continuing operations for the years ended August 31,
2009 and 2008, under this guidance are $2.01 and $3.51, respectively, as compared to $2.05 and $3.57 previously
reported for these periods.

54

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

ACUITY BRANDS, INC.

In December 2007, the FASB issued guidance within ASC Topic 805, Business Combinations (“ASC 805”),
which changes the accounting for business combinations through a requirement to recognize 100% of the fair values
of assets acquired, liabilities assumed, and noncontrolling interests in acquisitions of less than a 100% controlling
interest when the acquisition constitutes a change in control of the acquired entity. Other requirements include
capitalization of acquired in-process research and development assets, expensing, as incurred, acquisition-related
transaction costs and capitalizing restructuring charges as part of the acquisition only if requirements of ASC Topic
420, Exit or Disposal Obligations (“ASC 420”), are met. The standard was effective for business combination
transactions for which the acquisition date was on or after the beginning of the first annual reporting period
beginning on or after December 15, 2008 and was therefore adopted by the Company on September 1, 2009. See the
Acquisitions footnote for the impact of business combinations under this guidance on the Company’s financial
position, results of operations, and cash flows.

In December 2007, the FASB issued guidance within ASC Topic 810, Consolidation (“ASC 810”), that
establishes the economic entity concept of consolidated financial statements, stating that holders of a residual
economic interest in an entity have an equity interest in the entity, even if the residual interest is related to only a
portion of the entity. Therefore, this standard requires a noncontrolling interest to be presented as a separate
component of equity. The standard also states that once control is obtained, a change in control that does not result in
a loss of control should be accounted for as an equity transaction. The statement requires that a change resulting in a
loss of control and deconsolidation is a significant event triggering gain or loss recognition and the establishment of
a new fair value basis in any remaining ownership interests. The standard was effective for fiscal years beginning on
or after December 15, 2008 and was therefore adopted by the Company on September 1, 2009. The implementation
of this guidance had no effect on the Company’s financial position, results of operations, or cash flows, as the
Company does not currently consolidate an entity with a noncontrolling interest.

Accounting Standards Yet to Be Adopted

In September 2009, the FASB issued ASU No. 2009-14, Software (Topic 985) — Certain Revenue Arrange-
ments That Include Software Elements (“ASU 2009-14”). ASU 2009-14 changes the accounting model for revenue
arrangements that include both tangible products and software elements to allow for alternatives when vendor-
specific objective evidence does not exist. Under this guidance, tangible products containing software components
and non-software components that function together to deliver the tangible product’s essential functionality and
hardware components of a tangible product containing software components are excluded from the software
revenue guidance in Subtopic 985-605, Software — Revenue Recognition; thus, these arrangements are excluded
from this update. ASU 2009-14 is effective prospectively for revenue arrangements entered into or materially
modified in fiscal years beginning on or after June 15, 2010 with early adoption permitted. ASU 2009-14 is
therefore effective for the Company no later than the beginning of fiscal 2011. The Company is currently in the
process of determining the impact, if any, of adoption of the provisions of ASU 2009-14.

In September 2009, the FASB issued ASU No. 2009-13, Revenue Recognition (Topic 605) — Multiple-
Deliverable Revenue Arrangements (“ASU 2009-13”). ASU 2009-13 addresses the accounting for multiple-
deliverable arrangements to enable vendors to account for products or services (“deliverables”) separately rather
than as a combined unit. Specifically, this guidance amends the criteria in Subtopic 605-25, Revenue Recognition —
Multiple-Element Arrangements, of the Codification for separating consideration in multiple-deliverable arrange-
ments. A selling price hierarchy is established for determining the selling price of a deliverable, which is based on:
(a) vendor-specific objective evidence; (b) third-party evidence; or (c) company-specific estimates. This guidance
also eliminates the residual method of allocation and requires that arrangement consideration be allocated at the
inception of the arrangement to all deliverables using the relative selling price method. Additional disclosures
related to a vendor’s multiple-deliverable revenue arrangements are also required by this update. ASU 2009-13 is
effective prospectively for revenue arrangements entered into, or materially modified, in fiscal years beginning on
or after June 15, 2010 with early adoption permitted. ASU 2009-13 is therefore effective for the Company no later

55

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

ACUITY BRANDS, INC.

than the beginning of fiscal 2011. The Company is currently in the process of determining the impact, if any, of
adoption of the provisions of ASU 2009-13.

5. Fair Value Measurements

The Company determines a fair value measurement based on the assumptions a market participant would use
in pricing an asset or liability. ASC 820, Fair Value Measurements and Disclosures (“ASC 820”), established a three
level hierarchy making a distinction between market participant assumptions based on (i) unadjusted quoted prices
for identical assets or liabilities in an active market (Level 1), (ii) quoted prices in markets that are not active or
inputs that are observable either directly or indirectly for substantially the full term of the asset or liability (Level 2),
and (iii) prices or valuation techniques that require inputs that are both unobservable and significant to the overall
fair value measurement (Level 3).

The following table presents information about assets and liabilities required to be carried at fair value and

measured on a recurring basis as of August 31, 2010 and 2009:

(1) The Company maintains certain investments that generate returns that offset changes in certain liabilities

related to deferred compensation arrangements.

(2) The Company maintains a self-directed, non-qualified deferred compensation plan structured as a rabbi trust

primarily for certain retired executives and other highly compensated employees.

The Company utilizes valuation methodologies to determine the fair values of its financial assets and liabilities
in conformity with the concepts of “exit price” and the fair value hierarchy as prescribed in ASC 820. All valuation
methods and assumptions are validated at least quarterly to ensure the accuracy and relevance of the fair values.
There were no material changes to the valuation methods or assumptions used to determine fair values during the
current period.

The Company used the following valuation methods and assumptions in estimating the fair value of the

following assets and liabilities:

Cash and cash equivalents are classified as Level 1 assets. The carrying amounts for cash reflect the
assets’ fair values, and the fair values for cash equivalents are determined based on quoted market prices.

Long-term investments are classified as Level 1 assets. These investments consist primarily of publicly
traded marketable equity securities and fixed income securities, and the fair values are obtained through
market observable pricing.

Deferred compensation plan liabilities are classified as Level 1 within the hierarchy. The fair values of the
liabilities are directly related to the valuation of the long-term investments held in trust for the plan. Hence, the
carrying value of the deferred compensation liability represents the fair value of the investment assets.

The Company does not have any assets or liabilities that are carried at fair value and measured on a recurring
basis classified as Level 3 assets or liabilities. In addition, no transfers between the levels of the fair value hierarchy

56

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

ACUITY BRANDS, INC.

occurred during the current fiscal period. In the event of a transfer in or out of Level 1, the transfers would be
recognized on the date of occurrence.

Disclosures of fair value information about financial instruments, whether or not recognized in the balance
sheet, for which it is practicable to estimate that value are required each reporting period in addition to any financial
instruments carried at fair value on a recurring basis as prescribed by ASC 825, Financial Instruments, (“ASC 825”).
In cases where quoted market prices are not available, fair values are based on estimates using present value or other
valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount
rate and estimates of future cash flows.

The carrying values and estimated fair values of certain of the Company’s financial instruments were as

follows at August 31, 2010 and 2009:

Assets:
Investments in nonconsolidating affiliates . .
Liabilities:
Senior unsecured public notes, net of

unamortized discount . . . . . . . . . . . . . . .

Investments in nonconsolidating affiliates represented a strategic investment of less than a 20% ownership
interest in Renaissance, and, prior to the date of change of control, the Company did not maintain power over or
control of the entity. The Company accounted for this investment using the cost method. Therefore, the historical
cost of the acquired shares represented the carrying value of the investment. In July 2010, the Company acquired the
remaining capital stock in and control of Renaissance and accounted for the transaction in accordance with
ASC 805.

Notes are carried at the outstanding balance, including bond discounts, as of the end of the reporting period.
Fair value is estimated based on the discounted future cash flows using rates currently available for debt of similar
terms and maturity.

The tax-exempt industrial revenue bond is carried at the outstanding balance as of the end of the reporting
period. The industrial revenue bond is a tax-exempt, variable-rate instrument that resets on a weekly basis, and,
therefore, the Company estimates that the face amount of the bond approximates fair value as of August 31, 2010.

ASC 825 excludes certain financial instruments and all nonfinancial instruments from its disclosure require-
ments. Accordingly, the aggregate fair value amounts presented do not represent the underlying value of the
Company. In many cases, the fair value estimates cannot be substantiated by comparison to independent markets,
nor can the disclosed value be realized in immediate settlement of the instruments. In evaluating the Company’s
management of liquidity and other risks, the fair values of all assets and liabilities should be taken into
consideration, not only those presented above.

Nonrecurring Fair Value Measurements

As part of the streamlining actions taken during the second quarter of fiscal 2010, the Company recorded $3.7
in asset impairments related to the closure of a manufacturing facility and the abandonment of plant equipment. The
Company’s restructuring plans triggered impairment indicators, which required the testing of the recoverability of
the building and equipment per ASC 360. The fair value of the assets were estimated based primarily on

57

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

ACUITY BRANDS, INC.

undiscounted cash flows due to the short useful lives of the assets (e.g., less than one year) and the Company’s
intentions for future use.

As of February 28, 2010, the manufacturing facility had a total carrying value of $3.4 prior to the announced
plan to close. Through cash flow analysis and local commercial real estate market analysis, including the existence
of a market for the facility, or lack thereof, the Company determined that the fair value of the property approximated
zero. Thus, an impairment charge for the entire carrying value of the facility was incurred. Due to the methodology
and inputs (i.e., undiscounted future cash flows, broker quotes, and probability analysis) employed to determine the
fair value of the property, the manufacturing facility was concluded to be a Level 3 asset within the fair value
hierarchy.

Plant equipment associated with the aforementioned facility had a carrying value of $0.3 as of February 28,
2010. Based on the lack of future use of the equipment and intended disposal, the assets were determined to be
impaired during the second quarter of fiscal 2010 for the full net book value. Since management’s intent and use for
the asset changed and no observable market data or inputs were utilized to determine the fair value of the equipment,
the equipment was determined to be a Level 3 asset within the fair value hierarchy.

In addition to the aforementioned asset impairments, the Company recognized an impairment charge during
the fourth quarter of fiscal 2010 of approximately $1.4, which was related primarily to the diminished fair value of
its held-for-sale facility located in Decatur, GA. Based on market evidence (e.g., offers, broker quotes, and similar
property), the carrying value of the property ($4.0) was deemed greater than the market value for manufacturing
plants of similar size within the area, which correlates with the declines in commercial property values nationwide,
and an impairment charge of $1.0 was recorded. Additionally, the impaired plant was concluded to be a Level 3
asset within the fair value hierarchy.

6. Pension and Profit Sharing Plans

The Company has several pension plans, both qualified and non-qualified, covering certain hourly and salaried
employees. Benefits paid under these plans are based generally on employees’ years of service and/or compensation
during the final years of employment. The Company makes annual contributions to the plans to the extent indicated
by actuarial valuations and statutory requirements. Plan assets are invested primarily in equity and fixed income
securities.

Effective for fiscal 2009, the Company adopted the measurement date provisions within ASC 715. Prior to
2009, the Company measured the funded status of its plans as of May 31 of each year. The requirement to measure
plan assets and benefit obligations as of the date of the employer’s fiscal year-end statement of financial position
was effective for fiscal years ending after December 15, 2008, and was therefore effective for the Company in fiscal
2009. The change in measurement date to August 31 resulted in a reduction to retained earnings of approximately
$0.5, net of tax, during fiscal 2009.

It is the Company’s policy to adjust, on an annual basis, the discount rate used to determine the projected
benefit obligation to approximate rates on high-quality, long-term obligations based on the Company’s estimated
benefit payments available as of the measurement date. The Company uses a publicly published yield curve to assist
in the development of its discount rates. The Company estimates that each 100 basis point increase in the discount
rate would result in reduced net periodic pension cost of approximately $0.8 for domestic plans. The Company’s
discount rate used in computing the net periodic benefit cost for its domestic plans decreased by 25 basis points in
2010, which contributed to the change in net periodic pension cost associated with those plans. The discount rate
used in computing the net periodic pension cost for the Company’s international plans decreased 10 basis points in
2010 over the prior year. In addition, lower average asset values, a lower expected return on plan assets, and an

actuarial loss resulted in higher overall periodic benefit costs for 2010. The expected return on plan assets is derived
from a periodic study of long-term historical rates of return on the various asset classes included in the Company’s
targeted pension plan asset allocation. The Company estimates that each 100 basis point reduction in the expected
return on plan assets would result in additional net periodic pension cost of $0.8 and $0.1 for domestic plans and
international plans, respectively. The rate of compensation increase is also evaluated and is adjusted by the
Company, if necessary, annually.

The Company’s investment objective for U.S. plan assets is to earn a rate of return sufficient to match or exceed
the long-term growth of the plans’ liabilities without subjecting plan assets to undue risk. The plan assets are
invested primarily in high quality equity and debt securities. The Company conducts a periodic strategic asset
allocation study to form a basis for the allocation of pension assets between various asset categories. Specific
allocation percentages are assigned to each asset category with minimum and maximum ranges established for
each. The assets are then managed within these ranges. During 2010, the U.S. targeted asset allocation was 55%
equity securities, 40% fixed income securities, and 5% real estate securities. The Company’s investment objective
for the international plan assets is also to add value by matching or exceeding the long-term growth of the plans’
liabilities. During 2010, the international asset target allocation was 84% equity securities, 14% fixed income
securities, and 2% real estate funds.

The Company’s pension plan asset allocation at August 31, 2010 and 2009 by asset category is as follows:

Publicly-traded securities are valued at the last reported sales price on the last business day of the period.
Investments traded in the over-the-counter market and listed securities for which no sale was reported on the last day
of the period are valued at the last reported bid price.

Investments in real estate are stated at estimated fair values based on the fund management’s valuations and
upon appraisal reports prepared periodically by independent real estate appraisers. These investments are classified
as Level 3 assets within the fair value hierarchy. The purpose of the appraisal is to estimate the fair value of the real
estate as of a specific date based on the most probable price for which the appraised real estate will sell in a
competitive market under all conditions requisite to a fair sale. Estimated fair value is based on (i) discounted cash
flows using certain market assumptions, including holding period, discount rates, capitalization rates, rent and
expense growth rates, future capital expenditures and the ultimate sale of the property at the end of the holding
period; (ii) direct capitalization method; or (iii) comparable sales method.

The Company expects to contribute approximately $5.8 and $1.0 to its domestic and international defined
benefit plans, respectively, during 2011. These amounts are based on the total contributions required during 2011 to
satisfy current legal minimum funding requirements for qualified plans and estimated benefit payments for non-
qualified plans.

Benefit payments are made primarily from funded benefit plan trusts. Benefit payments are expected to be paid

as follows for the years ending August 31:

The Company also has defined contribution plans to which both employees and the Company make
contributions. The cost to the Company for these plans was $4.0 in 2010, $4.3 in 2009, and $5.5 in 2008.
Employer matching amounts are allocated in accordance with the participants’ investment elections for elective
deferrals. At August 31, 2010, assets of the domestic defined contribution plans included shares of the Company’s
common stock with a market value of approximately $5.6, which represented approximately 3.1% of the total fair
market value of the assets in the Company’s domestic defined contribution plans.

All future annual principal payments of long-term debt in the amount of $353.3 will become due after fiscal

2016.

On December 1, 2009, the Company simultaneously announced the private offering by ABL, Acuity Brands’
wholly-owned principal operating subsidiary, of $350.0 aggregate principal amount of senior unsecured notes due
in fiscal 2020 (the “Notes”) and the cash tender offer for the $200.0 of publicly traded notes outstanding that were
scheduled to mature in August 2010 (the “2010 Notes”). In addition to the retirement of the 2010 Notes, the
Company used the proceeds to repay the $25.3 outstanding balance on a three-year unsecured promissory note
issued to the former sole shareholder of Sensor Switch as part of ABL’s acquisition of Sensor Switch during fiscal
2009, as discussed below, with the remainder used for general corporate purposes.

The Notes are fully and unconditionally guaranteed on a senior unsecured basis by Acuity Brands and ABL IP
Holding LLC (“ABL IP Holding”, and, together with Acuity Brands, the “Guarantors”), a wholly-owned subsidiary
of Acuity Brands. The Notes are senior unsecured obligations of ABL and rank equally in right of payment with all
of ABL’s existing and future senior unsecured indebtedness. The guarantees of Acuity Brands and ABL IP Holding
are senior unsecured obligations of Acuity Brands and ABL IP Holding and rank equally in right of payment with
their other senior unsecured indebtedness. The Notes bear interest at a rate of 6% per annum and were issued at a
price equal to 99.797% of their face value and for a term of 10 years. Interest on the Notes is payable semi-annually
on June 15 and December 15, commencing on June 15, 2010. Additionally, the Company capitalized $3.1 of
deferred issuance costs related to the Notes that are being amortized over the 10-year term of the Notes.

In accordance with the registration rights agreement by and between ABL and the Guarantors and the initial
purchasers of the Notes, ABL and the Guarantors to the Notes filed a registration statement with the SEC for an offer
to exchange the Notes for SEC-registered notes with substantially identical terms. The registration became effective
on August 17, 2010, and all of the Notes were exchanged.

As noted above, the Company retired all of the outstanding 2010 Notes through the execution of a cash tender
offer and the subsequent redemption of any remaining 2010 Notes during fiscal 2010. The loss on the transaction,
including the premium paid, expenses, and the write-off of deferred issuance costs associated with the 2010 Notes,
was approximately $10.5.

On April 20, 2009, ABL issued a three-year unsecured promissory note at a 6% interest rate in the amount of
$30.0 to the former sole shareholder of Sensor Switch, who continued as an employee of the Company upon
completion of the acquisition, as partial consideration for the acquisition of Sensor Switch during the third quarter

64

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

ACUITY BRANDS, INC.

of fiscal 2009. In accordance with certain rights to accelerate the repayment of the promissory note, ABL paid the
outstanding principal balance of $25.3 with proceeds from the Notes in January 2010. No penalty or loss was
incurred by the Company due to the prepayment of the promissory note.

The $4.0 industrial revenue bond matures in 2021. The interest rates on the $4.0 bond were approximately

0.4% and 0.5% at August 31, 2010 and 2009, respectively.

Lines of Credit

On October 19, 2007, the Company executed a $250.0 revolving credit facility (the “Revolving Credit
Facility”). The Revolving Credit Facility matures in October 2012 and contains financial covenants, including a
minimum interest coverage ratio and a leverage ratio (“Maximum Leverage Ratio”) of total indebtedness to
EBITDA (earnings before interest, taxes, depreciation and amortization expense), as such terms are defined in the
Revolving Credit Facility agreement. These ratios are computed at the end of each fiscal quarter for the most recent
12-month period. The Revolving Credit Facility allows for a Maximum Leverage Ratio of 3.50, subject to certain
conditions defined in the financing agreement. The Company was compliant with all financial covenants under the
Revolving Credit Facility as of August 31, 2010. At August 31, 2010, the Company had additional borrowing
capacity under the Revolving Credit Facility of $242.7 under the most restrictive covenant in effect at the time,
which represents the full amount of the Revolving Credit Facility less outstanding letters of credit of $7.3 discussed
below.

The Revolving Credit Facility bears interest at the option of the borrower based upon either (1) the higher of
the JPMorgan Chase Bank prime rate and the federal funds effective rate plus 0.50%, or (2) the London Inter Bank
Offered Rate (“LIBOR”) plus the Applicable Margin (a margin as determined by Acuity Brands’ leverage ratio).
Based upon Acuity Brands’ leverage ratio, as defined in the Revolving Credit Facility agreement, the Applicable
Margins were 0.50% and 0.41% as of August 31, 2010 and 2009, respectively. During both fiscal 2010 and 2009, the
Company paid commitment fees at a rate of approximately 0.1%, and commitment fees paid during each of those
years were approximately $0.2.

At August 31, 2010, the Company had outstanding letters of credit totaling $11.5, primarily for securing
collateral requirements under the casualty insurance programs for Acuity Brands and for providing credit support
for the Company’s industrial revenue bond. At August 31, 2010, a total of $7.3 of the letters of credit was issued
under the Revolving Credit Facility, thereby reducing the total availability under the facility by such amount.

None of the Company’s existing debt instruments, neither short-term nor long-term, include provisions that

would require an acceleration of repayments based solely on changes in the Company’s credit ratings.

8. Common Stock and Related Matters

Stockholder Protection Rights Agreement

The Company’s Board of Directors has adopted a Stockholder Protection Rights Agreement (the “Rights
Agreement”). The Rights Agreement contains provisions that are intended to protect the Company’s stockholders in
the event of an unsolicited offer to acquire the Company, including offers that do not treat all stockholders equally
and other coercive, unfair, or inadequate takeover bids and practices that could impair the ability of the Company’s
Board of Directors to fully represent stockholders’ interests. Pursuant to the Rights Agreement, the Company’s
Board of Directors declared a dividend of one “Right” for each outstanding share of the Company’s common stock
as of November 16, 2001. The Rights will be represented by, and trade together with, the Company’s common stock
until and unless certain events occur, including the acquisition of 15% or more of the Company’s common stock by
a person or group of affiliated or associated persons (with certain exceptions, “Acquiring Persons”). Unless

65

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

ACUITY BRANDS, INC.

previously redeemed by the Company’s Board of Directors, upon the occurrence of one of the specified triggering
events, each Right that is not held by an Acquiring Person will entitle its holder to purchase one share of common
stock or, under certain circumstances, additional shares of common stock at a discounted price. The Rights will
cause substantial dilution to a person or group that attempts to acquire the Company on terms not approved by the
Company’s Board of Directors. Thus, the Rights are intended to encourage persons who may seek to acquire control
of the Company to initiate such an acquisition through negotiation with the Board of Directors.

During fiscal 2010, the Company reacquired approximately 512,300 shares of the Company’s outstanding
common stock, which completed the repurchase of ten million shares previously authorized by the Board of
Directors. As of August 31, 2010, the Company had repurchased the ten million shares at a cost of $414.0 under this
repurchase plan. In July 2010, the Company’s Board of Directors also authorized the repurchase of an additional
two million shares, or almost 5%, of the Company’s outstanding common stock, of which approximately
535,500 shares were repurchased in fiscal 2010 under this plan at a cost of $20.5. During fiscal 2010, the
Company re-issued slightly more than 140,000 shares as partial consideration for the acquisition of LC&D. The re-
issued shares were removed from treasury stock using the FIFO cost method. At fiscal year-end, the remaining
8.3 million repurchased shares were recorded as treasury stock at original repurchase cost of $355.7.

Preferred Stock

The Company has 50 million shares of preferred stock authorized, 5 million of which have been reserved for
issuance under the Stockholder Protection Rights Agreement. No shares of preferred stock had been issued at
August 31, 2010 and 2009.

Earnings per Share

Basic earnings per share is computed by dividing net earnings available to common stockholders by the
weighted average number of common shares outstanding, which has been modified to include the effects of all
participating securities (unvested share-based payment awards with a right to receive nonforfeitable dividends) as
prescribed by the two-class method under ASC 260, during the period. Diluted earnings per share is computed
similarly but reflects the potential dilution that would occur if dilutive options were exercised and restricted stock
awards were vested. Stock options of approximately 281,000 and 334,000 were excluded from the diluted earnings

In accordance with ASC 260, of which updated provisions became effective September 1, 2009, the
computation of weighted-average shares outstanding has been modified to include unvested share-based payment
awards with rights to receive nonforfeitable dividends as participating securities. The application of the standard
decreased both basic and diluted EPS by $0.04 for the year ended August 31, 2009, and decreased basic and diluted
EPS by $0.08 and $0.06, respectively, for the year ended August 31, 2008, as compared to the previously reported
amounts.

9. Share-Based Payments

Long-term Incentive and Directors’ Equity Plans

Effective November 30, 2001, the Company adopted the Acuity Brands, Inc., Long-Term Incentive Plan (the
“Plan”) for the benefit of officers and other key management personnel. An aggregate of 8.1 million shares were
originally authorized for issuance under that plan. In October 2003, the Board of Directors approved the Acuity
Brands, Inc., Amended and Restated Long-Term Incentive Plan (the “Amended Plan”), including an increase of

67

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

ACUITY BRANDS, INC.

5 million in the number of shares available for grant. However, the Board of Directors subsequently committed that
not more than 3 million would be available without further shareholder approval. In December 2003, the
shareholders approved the Amended Plan. The Amended Plan provides for issuance of share-based awards,
including stock options and performance-based and time-based restricted stock awards. The Amended Plan was
further amended in October 2007, including the release of the remaining 2 million shares and an increase of an
additional 500,000 shares. In January 2008, the shareholders approved the Amended Plan. In addition to the
Amended Plan, in November 2001, the Company adopted the Acuity Brands, Inc., 2001 Nonemployee Directors’
Stock Option Plan (the “Directors’ Plan”), under which 300,000 shares were authorized for issuance. In January
2007, the Directors’ Plan was amended to provide that no further annual grants of stock options would be made to
nonemployee directors.

Restricted Stock Awards

As of August 31, 2010, the Company had approximately 640,000 shares outstanding of restricted stock to
officers and other key employees under the Amended Plan. The shares vest over a four-year period and are valued at
the closing stock price on the date of the grant. Compensation expense recognized in continuing operations related
to the awards under the Amended Plan was $8.0, $9.0, and $8.2 in fiscal 2010, 2009, and 2008, respectively.

Additionally, the Company awarded restricted stock to certain employees on an individual basis based on a
number of factors, including individual achievements, additional job responsibilities, relocation, and employee
recruitment and retention, in fiscal 2010 and prior years. As of August 31, 2010, approximately 188,000 shares
related to these awards were outstanding. Compensation expense recognized in continuing operations related to
these awards was $1.8, $1.6, and $1.4 in fiscal 2010, 2009, and 2008, respectively.

Activity related to restricted stock awards during the fiscal year ended August 31, 2010 was as follows:

As of August 31, 2010, there was $16.8 of total unrecognized compensation cost related to unvested restricted
stock. That cost is expected to be recognized over a weighted-average period of 2.2 years. The total fair value of
shares vested during the years ended August 31, 2010 and 2009, was approximately $10.3 and $9.3, respectively.

Stock Options

Options issued under the Amended Plan are generally granted with an exercise price equal to the fair market
value of the Company’s stock on the date of grant and expire 10 years from the date of grant. These options
generally vest and become exercisable over a three-year period. The stock options granted under the Directors’ Plan
vest and become exercisable one year from the date of grant. These options have an exercise price equal to the fair
market value of the Company’s stock on the date of the grant and expire 10 years from that date. As of August 31,
2010, approximately 200,000 shares had been granted under the Director’s Plan. Shares available for grant under all
plans were approximately 2.9 million, 3.2 million, and 3.8 million at August 31, 2010, 2009, and 2008, respectively.
Forfeited shares and shares that are exchanged to offset taxes are returned to the pool of shares available for grant.
The Directors’ Plan was frozen with respect to future awards effective January 1, 2007.

68

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

ACUITY BRANDS, INC.

The fair value of each option was estimated on the date of grant using the Black-Scholes model. The dividend
yield was calculated based on annual dividends paid and the trailing 12-month average closing stock price at the
time of grant. Expected volatility was based on historical volatility of the Company’s stock, calculated using the
most recent time period equal to the expected life of the options. The risk-free interest rate was based on the
U.S. Treasury yield for a term equal to the expected life of the options at the time of grant. The Company used
historical exercise behavior data of similar employee groups to determine the expected life of options. All inputs
into the Black-Scholes model are estimates made at the time of grant. Actual realized value of each option grant
could materially differ from these estimates, without impact to future reported net income.

The following weighted average assumptions were used to estimate the fair value of stock options granted in

the fiscal years ended August 31:

In addition to the options granted as a part of the annual incentive award, the Board of Directors approved
supplemental option grants related to the assumption of additional duties by certain key employees, which were
granted in April 2009 and June 2010. As a result, the assumptions used in fiscal 2010 and 2009 are reflected as a
range of values.

The total intrinsic value of options exercised during the years ended August 31, 2010 and 2009 was $7.3 and
$5.6, respectively. As of August 31, 2010, the total intrinsic value of options outstanding and expected to vest were
$16.7 and $16.4, respectively, and the total intrinsic value of options exercisable was $14.3. As of August 31, 2010,
there was $2.5 of total unrecognized compensation cost related to unvested options. That cost is expected to be
recognized over a weighted-average period of approximately 1.6 years.

Employee Stock Purchase Plan

Employees are able to purchase, through payroll deduction, common stock at a 5% discount on a monthly
basis. There were 1.5 million shares of the Company’s common stock reserved for purchase under the plan, of which
approximately 1.1 million shares remain available as of August 31, 2010. Employees may participate at their
discretion.

Share Units

The Company requires its Directors to defer at least 50% of their annual retainer into the Directors’ Deferred
Compensation Plan. Under this plan, until June 29, 2006, the deferred cash was converted into share units using the
average of the high and low prices for the five days prior to the deferral date. The share units were adjusted to current
market value each month and earned dividend equivalents. Upon retirement, the Company distributed cash to the
retiree in a lump sum or in five annual installments. The distribution amount was calculated as share units times the

70

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

ACUITY BRANDS, INC.

average of the high and low prices for the five days prior to distribution (defined as “fair market value” in the
Directors’ Deferred Compensation Plan). On June 29, 2006, the Board of Directors amended this plan to convert
existing share units and future deferrals to cash-based, interest bearing deferrals at fair market value or stock-based
deferrals, with distribution only in the elected form upon retirement. Existing share deferrals were valued at the fair
market value at the date of election and future share deferrals will be calculated at fair market value at the date of the
deferral and will no longer vary with fluctuations in the Company’s stock price. As of August 31, 2010,
approximately 190,000 share units were accounted for in this plan.

Additionally, the Company allowed employees to defer a portion of restricted stock awards granted in fiscal
2003 and fiscal 2004 into the Supplemental Deferred Savings Plan as share units. Those share units were adjusted to
the current market value at the end of each month. On June 29, 2006, the Board of Directors amended this plan to
distribute those share unit deferrals in stock rather than cash. The shares were valued at the closing stock price on the
date of conversion and expense related to these shares will no longer vary with fluctuations in the Company’s stock
price. As of August 31, 2010, approximately 55,000 fully vested share units were accounted for in this plan.

Treatment of Stock Options, Restricted Stock Awards, and Restricted Stock Units pursuant to the Spin-off
of Zep

The employee benefits agreement entered into between the Company and Zep Inc. provided that at the time of
the Spin-off, Company stock options held by Zep’s current employees (but not former employees) were generally
converted to, and replaced by, Zep stock options in accordance with a conversion ratio such that the intrinsic value
of the underlying awards remains unaffected by the Spin-off. The employee benefits agreement also provided that,
at the time of the Spin-off, Company stock options held by current and former employees of the Company and
former Zep employees were adjusted with regard to the exercise price of and number of Acuity Brands shares
underlying the Company stock options to maintain the intrinsic value of the options, pursuant to the applicable long-
term incentive plan of the Company.

Each of the current and former employees of the Company and Zep holding unvested shares of restricted stock
of the Company received a dividend of one share of Zep restricted stock for each two shares of the Company’s
unvested restricted stock held. The shares of Zep stock received as a dividend are subject to the same restrictions and
terms as the Company’s restricted stock. The shares of Zep common stock were fully paid and non-assessable and
the holders thereof are not entitled to preemptive rights.

Effective immediately after the Spin-off of the specialty products business, the number of shares represented

by restricted stock units were converted in the same manner as the above mentioned stock option awards.

10. Commitments and Contingencies

Self-Insurance

It is the policy of the Company to self-insure — up to certain limits — traditional risks, including workers’
compensation, comprehensive general liability, and auto liability. The Company’s self-insured retention for each
claim involving workers’ compensation, comprehensive general liability (including product liability claims), and
auto liability is limited to $0.5 per occurrence of such claims. A provision for claims under this self-insured
program, based on the Company’s estimate of the aggregate liability for claims incurred, is revised and recorded
annually. The estimate is derived from both internal and external sources, including but not limited to the
Company’s independent actuary. The Company is also self-insured up to certain limits for certain other insurable
risks, primarily physical loss to property ($0.5 per occurrence) and business interruptions resulting from such loss
lasting two days or more in duration. Insurance coverage is maintained for catastrophic property and casualty
exposures, as well as those risks required to be insured by law or contract. The Company is fully self-insured for
certain other types of liabilities, including environmental, product recall, and patent infringement. The actuarial
estimates are subject to uncertainty from various sources, including, among others, changes in claim reporting

71

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

ACUITY BRANDS, INC.

patterns, claim settlement patterns, judicial decisions, legislation, and economic conditions. Although the Company
believes that the actuarial estimates are reasonable, significant differences related to the items noted above could
materially affect the Company’s self-insurance obligations, future expense, and cash flow. The Company is also
self-insured for the majority of its medical benefit plans. The Company estimates its aggregate liability for claims
incurred by applying a lag factor to the Company’s historical claims and administrative cost experience. The
appropriateness of the Company’s lag factor is evaluated and revised annually, as necessary.

Leases

The Company leases certain of its buildings and equipment under noncancelable lease agreements. Minimum
lease payments under noncancelable leases for years subsequent to August 31, 2010, are $15.0, $12.2, $8.9, $5.2,
$4.0, and $6.0 for fiscal 2011, 2012, 2013, 2014, 2015, and after 2016, respectively.

Total rent expense was $16.6, $18.2, and $18.8 in fiscal 2010, 2009, and 2008, respectively.

Purchase Obligations

The Company has incurred purchase obligations in the ordinary course of business that are enforceable and
legally binding. Obligations for years subsequent to August 31, 2010 include $80.9 in fiscal 2011. As of August 31,
2010, the Company had no purchase obligations extending beyond August 31, 2011.

Collective Bargaining Agreements

Approximately 61% of the Company’s total work force is covered by collective bargaining agreements.
Collective bargaining agreements representing approximately 34% of the Company’s work force will expire within
one year.

Litigation

The Company is subject to various legal claims arising in the normal course of business, including patent
infringement and product recall claims. Based on information currently available, it is the opinion of management
that the ultimate resolution of pending and threatened legal proceedings will not have a material adverse effect on
the financial condition, results of operations, or cash flows of the Company. However, in the event of unexpected
future developments, it is possible that the ultimate resolution of any such matters, if unfavorable, could have a
material adverse effect on the financial condition, results of operations, or cash flows of the Company in future
periods. The Company establishes reserves for legal claims when associated costs become probable and can be
reasonably estimated. The actual costs of resolving legal claims may be substantially higher than the amounts
reserved for such claims. However, the Company cannot make a meaningful estimate of actual costs to be incurred
that could possibly be higher or lower than the amounts reserved.

Environmental Matters

The operations of the Company are subject to numerous comprehensive laws and regulations relating to the
generation, storage, handling, transportation, and disposal of hazardous substances, as well as solid and hazardous
wastes, and to the remediation of contaminated sites. In addition, permits and environmental controls are required
for certain of the Company’s operations to limit air and water pollution, and these permits are subject to
modification, renewal, and revocation by issuing authorities. On an ongoing basis, the Company invests capital
and incurs operating costs relating to environmental compliance. Environmental laws and regulations have
generally become stricter in recent years. The cost of responding to future changes may be substantial. The
Company establishes reserves for known environmental claims when the associated costs become probable and can
be reasonably estimated. The actual cost of environmental issues may be substantially higher or lower than that
reserved due to difficulty in estimating such costs.

72

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

ACUITY BRANDS, INC.

Guarantees and Indemnities

The Company is a party to contracts entered into in the normal course of business in which it is common for the
Company to agree to indemnify third parties for certain liabilities that may arise out of or relate to the subject matter
of the contract. In most cases, the Company cannot estimate the potential amount of future payments under these
indemnities until events arise that would result in a liability under the indemnities.

In conjunction with the separation of their businesses (the “Distribution”), Acuity Brands and Zep entered into
various agreements that addressed the allocation of assets and liabilities and defined the Company’s relationship
with Zep after the Distribution, including a distribution agreement and a tax disaffiliation agreement. The
distribution agreement provides that Acuity Brands will indemnify Zep for liabilities related to the businesses
that comprise Acuity Brands. The tax disaffiliation agreement provides that Acuity Brands will indemnify Zep for
certain taxes and liabilities that may arise related to the Distribution and, generally, for deficiencies, if any, with
respect to federal, state, local, or foreign taxes of Zep for periods before the Distribution. Liabilities determined
under the tax disaffiliation agreement terminate upon the expiration of the applicable statutes of limitation for such
liabilities. There is no stated maximum potential liability included in the tax disaffiliation agreement or the
distribution agreement. The Company does not believe that any amounts it is likely to be required to pay under these
indemnities will be material to the Company’s results of operations, financial position, or liquidity. The Company
cannot estimate the potential amount of future payments under these indemnities because claims that would result in
a liability under the indemnities are not fully known.

Product Warranty and Recall Costs

Acuity Brands records an allowance for the estimated amount of future warranty claims when the related
revenue is recognized, primarily based on historical experience of identified warranty claims. However, there can be
no assurance that future warranty costs will not exceed historical experience. If actual future warranty costs exceed
historical amounts, additional allowances may be required, which could have a material adverse impact on the
Company’s results of operations and cash flows in future periods.

The changes in product warranty and recall reserves (included in Other accrued liabilities on the Consolidated

Balance Sheets) during the fiscal years ended August 31, 2010 and 2009 are summarized as follows:

11. Special Charge

During fiscal 2008, the Company commenced actions to streamline and simplify the Company’s organiza-
tional structure and operations. The charges consisted of severance and related employee benefit costs associated
with the elimination of certain positions worldwide, consolidation of certain manufacturing facilities, the estimated
costs associated with the early termination of certain leases, and share-based expense due to the modification of the
terms of agreements to accelerate vesting for certain terminated employees. These actions, including those taken in
fiscal 2009 as part of this program, are expected to allow the Company to better leverage efficiencies in its supply
chain and support areas, while funding continued investments in other areas that support future growth
opportunities.

During fiscal 2010, the Company continued its program to streamline operations, including the consolidation
of certain manufacturing facilities and the reduction of certain overhead costs. These actions are expected to allow

73

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

ACUITY BRANDS, INC.

the Company to better leverage efficiencies in its supply chain and support areas, while funding continued
investments in other areas that support future growth opportunities. During fiscal 2010, the Company recorded a
pre-tax charge of $8.4, or $0.13 after-tax per diluted share. The total pre-tax charge consists primarily of $3.3 for
estimated severances and employee benefits related to the planned consolidation of certain manufacturing
operations and a reduction in workforce and $5.1 for asset impairments related to the closing of a manufacturing
facility and the adjustment to fair value of an idle facility.

Approximately $49.7 of cumulative special charges related to these activities has been incurred through

August 31, 2010.

The changes in the reserves related to the program during the year ended August 31, 2010 (included in Accrued

Compensation on the Consolidated Balance Sheets) are summarized as follows:

12. Acquisitions

Renaissance Acquisition

On July 26, 2010, the Company acquired the remaining outstanding capital stock of Renaissance. Renaissance,
based in Herndon, Virginia, offered a full range of LED-based specification-grade downlighting luminaires and had
developed an extensive intellectual property portfolio related to advanced LED optical solutions and technologies.

Previously, the Company entered into a strategic partnership with Renaissance, which included a non-
controlling interest in the company and a license to the company’s intellectual property estate. Therefore, the
Company recognized an acquisition-in-stages as prescribed by ASC 805, which required the original equity
ownership interest to be revalued to the fair value as of the date of acquisition and included as part of the total
consideration given. Total consideration consisted of cash and the original noncontrolling interest.

Due to the provisions of ASC 805, the Company recognized an immaterial amount in acquisition costs in

current year earnings.

The operating results of Renaissance have been included in the Company’s consolidated financial statements
since the date of acquisition and are not material to the Company’s financial condition, results of operations, or cash
flows. Preliminary amounts related to the acquisition are reflected in the Consolidated Balance Sheets as of
August 31, 2010. These amounts are deemed to be provisional until disclosed otherwise as the Company continues
to gather information related to the identification and valuation of intangible and other acquired assets and
liabilities.

Sensor Switch Acquisition

On April 20, 2009, the Company acquired 100% of the outstanding capital stock of Sensor Switch, an industry-
leading developer and manufacturer of lighting controls and energy management systems. Sensor Switch, based in
Wallingford, Connecticut, offered a wide-breadth of products and solutions that substantially reduce energy
consumption including occupancy sensors, photocontrols, and distributed lighting control devices. Total consid-
eration for the purchase was approximately $205.0 consisting of 2 million shares of Acuity Brands’ common stock,
a $30.0 unsecured promissory note payable over three years, and approximately $130.0 of cash. The cash payment
was funded from available cash on hand and from borrowings under the Company’s existing Revolving Credit

Facility. The operating results of Sensor Switch have been included in the Company’s consolidated financial
statements since the date of acquisition. Management finalized the purchase price allocation during fiscal 2009, and
the amounts are reflected in the Consolidated Balance Sheets as of August 31, 2009.

LC&D Acquisition

On December 31, 2008, the Company acquired for cash and stock substantially all the assets and assumed
certain liabilities of LC&D. Located in Glendale, California, LC&D is a manufacturer of comprehensive digital
lighting controls and software that offered a breadth of products, ranging from dimming and building interfaces to
digital thermostats, all within a single, scalable system. The operating results of LC&D have been included in the
Company’s consolidated financial statements since the date of acquisition. Management finalized the purchase
price allocation during fiscal 2009, and the amounts are reflected in the Consolidated Balance Sheets as of
August 31, 2009.

See Subsequent Event footnote for post-financial statement date acquisition.

Income Taxes

The Company accounts for income taxes using the asset and liability approach as prescribed by ASC Topic
740, Income Taxes (“ASC 740”). This approach requires the recognition of deferred tax assets and liabilities for the
expected future tax consequences of events that have been included in the financial statements or tax returns. Using
the enacted tax rates in effect for the year in which the differences are expected to reverse, deferred tax liabilities and
assets are determined based on the differences between the financial reporting and the tax basis of an asset or
liability.

The provision for income taxes consists of the following components:

* Deferred income tax asset and a substantial portion of the valuation allowance relate to cumulative net
operating losses incurred by Renaissance up to the date of acquisition. The remaining valuation allowance
relates to certain state tax credits.

The Company currently intends to indefinitely reinvest all undistributed earnings of and original investments
in foreign subsidiaries, which amounted to approximately $33.8 at August 31, 2010; however, this amount could
fluctuate due to changes in business, economic, or other conditions. If these earnings were distributed to the U.S. in
the form of dividends or otherwise, or if the shares of the relevant foreign subsidiaries were sold or otherwise
transferred, the Company would be subject to additional U.S. income taxes (subject to an adjustment for foreign tax
credits) and foreign withholding taxes. Determination of the amount of unrecognized deferred income tax liability
related to these earnings or investments is not practicable.

As part of the Renaissance acquisition in fiscal 2010, the Company recognized deferred tax assets related to net
operating losses incurred by Renaissance, which are expected to expire between 2026 and 2031. In addition, the
Company recorded an estimated valuation allowance related to the recoverability of the deferred tax assets based on
Internal Revenue Service limitations, among other factors. At August 31, 2010, the Company recognized a
valuation allowance attributable to these deferred tax assets in the amount of $5.1. At August 31, 2009, no valuation
allowances on deferred tax assets were deemed necessary.

At August 31, 2010, the Company had state tax credit carryforwards of approximately $2.5, which will expire

between 2013 and 2018.

The gross amount of unrecognized tax benefits as of August 31, 2010, totaled $6.7, which includes $5.6 of net
unrecognized tax benefits that, if recognized, would affect the annual effective tax rate. The Company recognizes
potential interest and penalties related to unrecognized tax benefits as a component of income tax expense; such
accrued interest and penalties are not material. With few exceptions, the Company is no longer subject to United
States federal, state, and local income tax examinations for years ended before 2006 or for foreign income tax

examinations before 2004. The Company does not anticipate unrecognized tax benefits will significantly increase
or decrease within the next twelve months.

A reconciliation of the change in the unrecognized income tax benefit (reported in Other long-term liabilities

on the Consolidated Balance Sheets) for the year ended August 31, 2010 is as follows:

During fiscal 2010, the Company decreased its interest accrual associated with uncertain tax positions by
approximately $0.1. Total accrued interest as of August 31, 2010 was $0.8. There were no accruals related to income
tax penalties during fiscal 2010. Interest, net of tax benefits, and penalties are included in income tax expense. The
classification of interest and penalties did not change during the current fiscal year.

14. Subsequent Event

On October 14, 2010, the Company acquired for cash all of the outstanding capital stock of Winona Lighting,
Inc. (“Winona Lighting”), a premier provider of architectural and high-performance indoor and outdoor lighting
products headquartered in Minnesota. Recognized throughout the architectural design community, Winona
Lighting served the commercial, retail, and institutional markets with a product portfolio of high-quality and
design-oriented luminaires suitable for decorative, custom, asymmetric, and landscape lighting applications.

Due to the timing of the acquisition, the Company has only recently begun the analysis around the acquisition
method accounting for Winona Lighting. However, management does not currently believe that the purchase is
material to the Company’s overall financial condition, results of operations, and cash flows.

16. Supplemental Guarantor Condensed Consolidating Financial Statements

In December 2009, ABL, the wholly-owned and principal operating subsidiary of the Company, engaged in the
refinancing of the current debt outstanding through a private placement bond offering of $350.0 aggregate principal
amount of senior unsecured notes due in fiscal 2020. See Debt footnote for further information on the refinancing
activities.

In accordance with the registration rights agreement by and between ABL and the Guarantors and the initial
purchases of the Notes, ABL and the Guarantors to the Notes filed a registration statement with the SEC for an offer
to exchange the Notes for an issue of SEC-registered notes with identical terms. Due to the filing of the registration
statement and offer to exchange, the Company determined the need for compliance with Rule 3-10 of SEC
Regulation S-X (“Rule 3-10”). In lieu of providing separate audited financial statements for ABL and ABL IP
Holding, the Company has included the accompanying Condensed Consolidating Financial Statements in accor-
dance with Rule 3-10(d) of SEC Regulation S-X. The column marked “Parent” represents the financial condition,
results of operations, and cash flows of Acuity Brands. The column marked “Subsidiary Issuer” represents the
financial condition, results of operations, and cash flows of ABL. The column entitled “Subsidiary Guarantor”
represents the financial condition, results of operations, and cash flows of ABL IP Holding. Lastly, the column listed

as “Non-Guarantors” includes the financial condition, results of operations, and cash flows of the non-guarantor
direct and indirect subsidiaries of Acuity Brands, which consist primarily of foreign subsidiaries. Eliminations were
necessary in order to arrive at consolidated amounts. In addition, the equity method of accounting was used to
calculate investments in subsidiaries. Accordingly, this basis of presentation is not intended to present our financial
condition, results of operations, or cash flows for any purpose other than to comply with the specific requirements
for parent-subsidiary guarantor reporting.

Note:

Intercompany payable (receivable) within the non-guarantors column primarily represented intercompany
transactions between ABL and its direct subsidiary, Acuity Unlimited, Inc (“Acuity Unlimited”). The
equity interest in Acuity Unlimited offsets this receivable. As no operating activity existed in fiscal 2010,
Acuity Unlimited issued a return of capital in the amount of the capital investment made by ABL and settled
the intercompany balance outstanding during the year. The return of capital reduced intercompany
receivable and total equity for the non-guarantors column by approximately $230.0 and fully eliminated
all Acuity Unlimited balance sheet amounts. ABL experienced equal reductions in investments in
subsidiaries and net intercompany payables.

ABL and its direct subsidiary, Acuity Unlimited, Inc (“Acuity Unlimited”). As no operating activity existed
in fiscal 2010, Acuity Unlimited issued a return of capital in the amount of the capital investment made by
ABL and settled the intercompany balance outstanding during the year.

Item 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure

None.

Item 9a. Controls and Procedures

Disclosure controls and procedures are controls and other procedures that are designed to reasonably ensure
that information required to be disclosed in the reports filed or submitted by the Company under the Securities
Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the Securities
and Exchange Commission’s (“SEC”) rules and forms. Disclosure controls and procedures include, without
limitation, controls and procedures designed to reasonably ensure that information required to be disclosed by the
Company in the reports filed under the Securities Exchange Act is accumulated and communicated to management,
including the principal executive officer and principal financial officer, as appropriate to allow timely decisions
regarding required disclosure.

As required by SEC rules, the Company has evaluated the effectiveness of the design and operation of its
disclosure controls and procedures as of August 31, 2010. This evaluation was carried out under the supervision and
with the participation of management, including the principal executive officer and principal financial officer.
Based on this evaluation, these officers have concluded that the design and operation of the Company’s disclosure
controls and procedures are effective at a reasonable assurance level. However, because all disclosure procedures
must rely to a significant degree on actions or decisions made by employees throughout the organization, such as
reporting of material events, the Company and its reporting officers believe that they cannot provide absolute
assurance that all control issues and instances of fraud or errors and omissions, if any, within the Company will be
detected. Limitations within any control system, including the Company’s control system, include faulty judgments
in decision-making or simple errors or mistakes. In addition, controls can be circumvented by an individual, by
collusion between two or more people, or by management override of the control. Because of these limitations,
misstatements due to error or fraud may occur and may not be detected.

Management’s annual report on the Company’s internal control over financial reporting and the independent
registered public accounting firm’s attestation report are included in the Company’s 2010 Financial Statements in
Item 8 of this Annual Report on Form 10-K, under the headings, “Management’s Report on Internal Control over
Financial Reporting” and “Report of Independent Registered Public Accounting Firm on Internal Control Over
Financial Reporting”, respectively, and are incorporated herein by reference.

There have been no changes in the Company’s internal control over financial reporting that occurred during the
Company’s most recent completed fiscal quarter that have materially affected, or are reasonably likely to materially
affect, the Company’s internal control over financial reporting.

CEO and CFO Certifications

The Company’s Chief Executive Officer as well as the Chief Financial Officer have filed with the Securities
and Exchange Commission the certifications required by Section 302 of the Sarbanes-Oxley Act of 2002 as
Exhibits 31(a) and 31(b) to the Company’s Annual Report on Form 10-K for the fiscal year ended August 31, 2010.
In addition, on February 24, 2010, the Company’s CEO certified to the New York Stock Exchange that he was not
aware of any violation by the Company of the NYSE corporate governance listing standards.
