Analyst · Wells Fargo
Thank you, Dan. Good morning, everyone. Ricky and I would like to make a few comments, and then we'll be happy to answer your questions.
First, let me say we are very pleased with our results for the fourth quarter and for the full year 2012. We reported strong top and bottom line growth in spite of continued soft economic conditions. As we will explain, our reported results include the impact of our previously announced streamlining activities, which mask the significant improvement in performance of the company this quarter. This is the 10th quarter in a row where we achieved unit volume growth in an environment where spending for new nonresidential construction remains sluggish and inconsistent. I believe this is, yet again, strong evidence our strategy to diversify the end markets we serve and extend our leadership position in North America is succeeding. These strategies include the continued aggressive introduction of innovative, energy-efficient lighting solutions; expansion in key channels and geographies; and improvements in customer service.
Our profitability and cash flow for the quarter and full year were again strong even while we continue to fund areas with significant future growth potential, including the expansion of our solid-state luminaire and Lighting Controls portfolio.
As you well know, the economy in North America continues to be fragile, as consumer confidence lags and job growth remains anemic. Having said this, we believe the many channels and markets we serve are, for the most part, on the road to recovery. Also in the quarter, we continued to encounter rising costs for items such as freight and lamps. Overall, we estimate our pricing initiatives have allowed us to recover these higher input costs. I mention these macro factors because it provides a backdrop against which you can again see the outstanding performance of our company.
I know many of you have already seen our results, and Ricky will provide more detail later in the call, but I would like to make a few comments on the key highlights.
First, for the quarter. Net sales for the quarter were $514 million, an increase of almost 4% compared with the year-ago period. This level of growth is significant, given general economic and industry conditions. Reported operating profit was $61.2 million or 11.9% of sales. We took a special charge in the current quarter for previously announced streamlining actions and incurred expected inefficiencies associated with these actions, which in total reduced operating profit by $6.5 million in the quarter. Ricky will talk more about these special charges and these inefficiencies later in the call.
I find it helpful to add back these items to the current quarter's results to make them comparable with the prior year. Doing so, one can see adjusted operating profit was $67.7 million, up 21% over the year-ago period, while adjusterated [ph] operating profit margins improved 200 basis points to a strong 13.2%. Diluted earnings per share were $0.78. Again, adding back the impact of these items noted above, adjusted diluted EPS for the current quarter was $0.88, up 11%.
As Ricky will explain later, fluctuations in foreign currency reduced our diluted EPS by $0.04 in the quarter, while it benefited diluted EPS by $0.03 in the year-ago period. You can do your own math to get a true apple-to-apples comparison between quarters from an EPS perspective when eliminating the impact of these currency fluctuations. As you would expect, the growth is similar to the 21% growth we achieved in adjusted operating profit. Strong results indeed.
For the full year, net sales at Acuity were more than $1.9 billion, up almost 8% from 2011. Adjusted consolidated operating profit margin was 11.7%, up 120 basis points compared with the year-ago period. Adjusted diluted EPS was $3 per share, up 24% from 2011.
In addition, we generated over $172 million in net cash provided by operating activities. This is the 8th year out of the last 9 years where we have generated more free cash flow than our net income, a significant accomplishment. As Ricky will discuss later, we've meaningfully enhanced our already strong financial position in 2012 as net debt to total capitalization, net of cash, is now just over 7%.
Lastly, I'm pleased to report that we, once again, earned much more than our cost of capital and our cash flow return on investment was a robust 24%, 300 basis points better than last year in spite of these challenging economic conditions.
These results for the quarter and full year were significant improvements over the year-ago periods. We believe you will find these results even more impressive upon further analysis.
So first, let's look at the quarter. On a consolidated basis, net sales grew almost 4% compared with a year ago. Approximately 2/3 of the 4 points of growth were due to greater product shipments, with the balance coming from the benefits of better price and product mix. The impact of acquisitions and foreign currency on net sales were not significant. The increase in net sales was reasonably broad-based along most product lines, partially offset by a decline in renovation due to the timing of projects for certain large corporate accounts in the year-ago period. Growth in our largest channel, commercial and industrial, was well above this quarter's average due to continued emphasis on selling higher value-added lighting solutions, especially LED-based luminaires, which again grew by more than 2.5x compared with the year-ago period, as well as a continued focus on smaller- and medium-sized projects of various types.
We continue to enjoy solid growth in important geographies and channels in North America, as well as key markets internationally, all of which is very encouraging in spite of the variability in demand within the nonresidential construction market.
As we have noted before, it is impossible to precisely determine the separate impact that price and product mix changes have on our net sales. Having said that, we estimate the positive impact on sales from price mix was primarily due to the benefits from previously announced price increases to recover rising input costs.
We estimate our pricing actions helped offset approximately $4 million in higher input costs compared with the year-ago period. Looking at all this a bit more closely, there are some interesting points to note. First, we believe spending in key segments of the nonresidential construction market was up modestly in the quarter compared with a year ago, as was the lighting market. This is in contrast with our unit volume growth in North America, which was up more than 3% and even more in the C&I channel.
We believe our channel and product diversification, as well as our strategies to better serve customers with new, more innovative lighting solutions and the strength of our many sales forces, have allowed us to yet again outperform the markets we serve. Our solid growth in a challenging market is due in large part to our focused strategy to diversify our portfolio, to be less reliant on new building construction and more focused on growing portions of market, including renovation and lighting control solutions, that enhance the visual environment while optimizing energy usage.
Before I turn the call over to Ricky, I would like to comment on our profitability and the strategic accomplishments in the quarter and the full year. Excluding the impact of the special charge and the expected inefficiencies with plant consolidation, adjusted operating profit margin for the fourth quarter was a strong 13.2%, again up 200 basis points from the year-ago period. In fact, we earned more adjusted operating profit this quarter than any quarter since 2008, and this was our highest operating profit margin in the last 4 years. Further, as Ricky will discuss later in the call, adjusted gross profit margin expanded 140 basis points to 41.8% due to higher shipment volume, a better mix of products sold and improved productivity.
Next, selling, distribution and administrative expenses were 28.6% of net sales for the quarter, a decline of about 60 basis points from the year-ago period. Total SD&A was up only 1.7% on a sales increase of 3.6%. Productivity improvements helped to offset other increases in SD&A expenses, which were primarily related to activities focused on longer-term growth opportunities, including market diversification and investing in innovation and technology, primarily for solid-state luminaires and integrated intelligent lighting systems. Investments in these key areas are starting to pay off as our new products and solutions gain traction in the marketplace, driving revenue growth.
As a point of reference, SD&A that is not directly variable with sales volume was slightly less than $90 million this quarter, in line with the expectations noted in our last quarter's earnings call.
On the strategic front, we continued our rapid pace of introductions of new products, significantly expanding our industry-leading portfolio of innovative energy-efficient luminaires and lighting control solutions. The rapid introduction of innovative, more energy-efficient products and services have been key contributors to our improved performance over the last few years. This, contrary to the view of some, has allowed us to extend our market leadership position and is one of the cornerstones of our growth strategy going forward.
As I mentioned earlier, our solid-state lighting portfolio is expanding rapidly, as are the sales of these luminaires. Today, LED-based products are now approximately 12% of our total sales. And we continue to fund the development of other light source technology, such as organic LEDs, where we continue to expand our award-winning portfolio of these innovative products.
More impressively, our adjusted operating profit margins continued to expand this quarter, while sales of LED-based solutions have become a larger portion of our overall business. Acuity is a clear leader in digital lighting solutions. It is because we understand the sophisticated needs of our expansive customer base and are able to offer each tailored solutions from our industry-leading portfolio. Customers understand it takes more than just a chip, which is quickly becoming a commodity, or a fluorescent lamp to be a true lighting company like Acuity Brands. At Acuity, we offer customers superior quality lighting and energy-efficient solutions for virtually every indoor and outdoor application regardless of the light source. This is again why we are extending our industry-leading position.
As I've noted before, our organization has a long and distinguished history of leading and innovating during eras of technology disruption. Today is clearly no different. Acuity Brands is leading the evolution to intelligent lighting solutions with its broad and deep portfolio of indoor and outdoor solid-state and traditional energy-efficient luminaires and lighting controls. And we are delivering profitable growth and strong financial returns for our stakeholders while making these important investments.
For the full year, we performed exceedingly well in spite of another year of weak economic conditions. Just to note a few of the key highlights:
Net sales grew almost 8% over $1.9 billion, while adjusted operating profit margins expanded 120 basis points compared with the year-ago period. Our solid growth in this challenging environment was due in large part to our focused strategy to diversify our portfolio, to be less reliant on new building construction cycle and to expand in underpenetrated channels and geographies. Innovation and the record pace of new product introductions continued to fuel our growth. Interestingly, we sold as much LED-based luminaires in the fourth quarter of 2012 as we did in all of 2011.
Our formidable strength in innovation was on full display earlier in 2012, when, as I mentioned before, Acuity won a total of 11 industry awards at 2 key industry events for its indoor and outdoor LED lighting solutions. These awards included the prestigious "Best in Class" designation at the Next Generation Luminaires Solid State Lighting Design competition. No other competitor even came close to this level of success at these events.
Again, we are a lighting company. We are extending our leadership position because customers understand it takes more than simply slapping a chip on a board and shining it on someone's eyes and then claiming to be a real lighting company. These accomplishments have diversified and strengthened our foundation and will further serve as a robust platform for our future growth that is less reliant on the new commercial construction cycle. We have been able to produce these results because of the dedication and resolve of our 6,000 associates and the progress that they have made in 4 key areas of strategic focus: customer service; pricing and margin management; geographical channel and product portfolio expansion; and company-wide productivity.
I will talk more about our future growth strategies and our expectations for the construction market later in the call. I would like to now turn the call over to Ricky before I make a few comments regarding our focus for 2013 and beyond. Ricky?
