Acuity Brands Reports Fiscal 2014 Second Quarter Results

Net Sales Increase 12 Percent; Adjusted Diluted EPS Rises 21 Percent

ATLANTA, April 2, 2014 - Acuity Brands, Inc. (NYSE: AYI) (“Company”) today announced fiscal 2014 second quarter net sales of $546.2 million, an increase of $59.5 million, or 12 percent, compared with the year-ago period. Net income for the second quarter of fiscal 2014 was $32.7 million, an increase of $8.0 million, or 32 percent, compared with the prior-year period. Fiscal 2014 second quarter diluted EPS of $0.75 increased 32 percent compared with $0.57 for the year-ago period.

Excluding the impact of special charges and related temporary manufacturing inefficiencies associated with streamlining activities which were incurred primarily in the year-ago period (as further explained below), fiscal 2014 second quarter adjusted net income of $32.6 million increased $5.9 million, or 22 percent, compared prior year’s $26.7 million. Diluted EPS for the second quarter of fiscal 2014 of $0.75 increased 21 percent compared with prior-year’s adjusted diluted EPS of $0.62, which excludes the impact of special charges and related temporary manufacturing inefficiencies. A reconciliation of adjusted financial measures to the most directly comparable GAAP measure is provided in the tables at the end of this release.

Vernon J. Nagel, Chairman, President, and Chief Executive Officer of Acuity Brands, commented, “We were very pleased with our fiscal 2014 second quarter results as we continued to execute our strategies to extend our leadership position in North America. While we believe inclement winter weather in certain parts of the U.S. dampened customer orders during the quarter and somewhat impacted our operations, the year-over-year increase in net sales reflects continued favorable trends in order rates as well as the continued adoption of LED lighting solutions, which again more than doubled over the prior year. Sales of LED-based luminaires now represent 30 percent of our net sales. We believe our second quarter results reflect our ability to provide customers truly differentiated value from our industry-leading portfolio of innovative lighting and control solutions along with superior service.”

Second Quarter Results

The 12 percent year-over-year growth in fiscal 2014 second quarter net sales was due primarily to a 13 percent increase in sales volume, which was partially offset by a net unfavorable change in foreign currency rates, primarily because of a weaker Canadian Dollar. The impact from changes in the price and mix of products sold (“price/mix”) and recent acquisitions was benign. The increase in sales volume was broad-based across most product categories and key sales channels in North America.

Fiscal 2014 second quarter gross profit margin was 39.4 percent compared with prior year’s adjusted gross profit margin of 39.6 percent, which excludes the impact of temporary manufacturing inefficiencies directly attributable to the closing of a production facility in fiscal 2013. Fiscal 2014 second quarter gross profit margin was negatively impacted approximately 100 basis points due to a combination of higher warranty-related costs associated with a specific non-LED product, the impact of a net unfavorable change in foreign currency rates, and to a lesser degree, higher freight costs for expediting various components due primarily to service greater than expected customer demand for certain products. The total impact of these items reduced diluted EPS by approximately $0.09. Management believes inclement winter weather reduced net sales by as much as 3 percent which also impacted margins and profitability.

Operating profit for the second quarter of fiscal 2014 was $58.4 million, an increase of $13.3 million, or 30 percent, over the year-ago period. Fiscal 2014 second quarter adjusted operating profit (excluding the impact of a pre-tax $0.2 million favorable adjustment to special charges) increased $10.0 million, or 21 percent, to $58.2 million compared with prior-year’s adjusted operating profit (excluding the impact of a pre-tax $3.1 million special charge and related temporary expenses) of $48.2 million. Adjusted operating profit margin for the second quarter of fiscal 2014 increased 80 basis points to 10.7 percent compared with 9.9 percent for the prior-year period. The improvement in the adjusted operating profit margin was due primarily to increased sales and productivity gains, which was partially offset by the issues noted above which reduced gross profit margin by 100 basis points and higher variable incentive compensation.

Special Charges and Temporary Expenses Associated with Streamlining Activities

Management estimates that during the second quarter of fiscal 2014 the Company realized approximately $3.5 million of pre-tax savings associated with the streamlining activities initiated in 2013 and is now at the total annualized savings run rate of $15 million.

Prior year’s second quarter pre-tax special charge and temporary expenses totaling $3.1 million, or $0.05 per diluted share, were comprised of a pre-tax special charge of $0.3 million and $2.8 million of costs related to temporary manufacturing inefficiencies associated with the closing of the Cochran production facility. The special charge consisted principally of production transfer costs from the Cochran facility to other locations. The $2.8 million of manufacturing inefficiencies consisted primarily of non-productive operating costs at the

News Release

Cochran facility and expenses associated with the initial set-up of production at various facilities that assumed the production of products previously manufactured at the Cochran facility.

Year-to-Date Results

Net sales for the first six months of fiscal 2014 were $1,120.9 million compared with $967.8 million for the prior-year period, an increase of 15.8 percent. Fiscal 2014 first half reported results include operating profit of $135.8 million, net income of $77.2 million, and diluted EPS of $1.78. Adjusted results, which exclude special charges and related temporary manufacturing inefficiencies as well as the benefit of an insurance recovery of $5 million, or $0.07 diluted EPS, associated with the prior-year reported loss resulting from fraud perpetrated at a freight payment and audit service firm formerly retained by the Company, include adjusted operating profit of $130.6 million, or 11.7 percent of net sales, compared with adjusted operating profit of $101.9 million, or 10.5 percent of net sales, for the prior-year period. Adjusted net income for the first half of fiscal 2014 was $74.0 million compared with $56.3 million for the prior-year period. Adjusted diluted EPS for the first half of fiscal 2014 and 2013 was $1.71 and $1.31, respectively.

Outlook

Mr. Nagel commented, “Our outlook remains positive. Third-party forecasts and leading indicators suggest that the growth rate for the North American lighting market, which includes renovation and retrofit activity, will continue to be in the mid-to-upper single digit range during 2014. While we still expect to see some volatility in demand among certain sales channels and geographies, our expectation for the future is that overall demand in our end markets will continue to improve and be more consistent and broad-based. The favorable trend in our March order rates seems to reflect this continuing improvement. We believe opportunities continue to exist that will allow us to continue to outperform the markets we serve. These opportunities include benefits from growing renovation and tenant improvement projects, further expansion in underpenetrated geographies and channels, and growth from the introduction of new products and lighting solutions.”

Mr. Nagel concluded, “We believe 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 we believe we are well positioned to fully participate in this exciting industry.”

Non-GAAP Financial Measures

This news release contains non-GAAP financial measures such as “adjusted gross profit margin”, “adjusted selling, distribution, and administrative expenses” (“adjusted SD&A expenses”), “adjusted operating profit”, “adjusted operating profit margin”, “adjusted net income”, and “adjusted diluted EPS”.

prospects for the future.
