Analyst · Robert W. Baird
Good morning, and thank you for taking the time to join us today. I would like to start today's call by briefly reviewing our strategy, followed by the highlights of our second quarter results. I will then pass the call on to John Guthrie, who will walk you through our financial results in more detail. Pascal Convers will cover the update on our acquisition activities. And finally, I will come back to provide comments on our outlook before opening up the line for your questions.
I will start with Slide 4 of the earnings presentation. We continue to make progress executing our strategy, which we believe provides distinct opportunities to grow our business and create significant value for all stakeholders, both in the near term and over the longer term. As we explained during our last earnings call, our strategy combines the scale advantages and capabilities of a large company with the passion, deep knowledge and entrepreneurialism of our local teams, in order to deliver superior value to both our customers and our suppliers. This allows us to gain market share and achieve consistent superior organic growth and profitability. At the half point in the year, we have achieved 7% organic net sales growth, which is a reflection of our strategy. We complement our organic growth with acquisitive growth to achieve strong results for our stakeholders while extending our lead over the competition. And this was once again highlighted by our recent acquisition of Bissett earlier this month.
In addition to organic and acquisition growth, we also have the opportunity to expand our EBITDA margin as we execute our commercial and operational excellence initiatives. We are still in the early innings of these initiatives covering pricing, category management, supply chain, sales force performance and marketing. In the second quarter, SiteOne once again realized the benefits of these initiatives, expanding our gross margin by 220 basis points.
Turning to Slide 5, we are pleased with our financial and operational performance in the second quarter as we delivered solid results for the 3 months ended July 3, 2016, despite the pull forward of organic sales into the first quarter. I am particularly proud of our ability to execute during a period when we completed both our IPO and a debt recapitalization. A lot of time and hard work by our team resulted in well-executed transactions. With the IPO behind us and a strong capital structure in place, we are laser-focused on executing our strategy, growing SiteOne and delivering strong results for all stakeholders.
Net sales increased by 7% year-over-year in the quarter, reflecting good contribution from our acquisitions. Organic revenue declined by 2% in the quarter, but was balanced with 23% organic growth in Q1, resulting in a 7% overall increase for the first 6 months of 2016. Our organic growth for the second quarter was negatively impacted by the pull forward of sales into the first quarter due to the early spring and resulting very strong demand. In addition, as we mentioned on last quarter's call, weather conditions in April and May were unusually wet and therefore, unfavorable, followed by some improvement in June. As you've heard us say before, our business can be impacted by weather, both positively and negatively in the short term, but this tends to normalize over the course of the full year. And that's exactly what we experienced if you look at our combined organic growth results for the first half of the year.
Now let me address the previous forecast of 8% to 9% organic sales growth for the half year versus the 7% that we achieved. There were 2 reasons for this: First, we had an issue with our forecasting process. We provide seed to blenders, who then bag the seed and ship it back to us to be sold to our end customers. During our buildup to the forecast, we incorrectly included some of that seed volume to blenders in our estimates for the second quarter sales. Note that this issue had no effect on our forecast for EBITDA. We identified the issue and have since fixed our forecasting process to exclude this volume going forward; second, we did expect June to be a stronger month for our agronomic and nursery products. However, the hot and dry weather came early in June and dampened the quarter-end sales for these product lines.
Aside from these 2 issues, we feel good about delivering 7% organic sales growth and 19% total sales growth for the first 6 months, which reflects our growing market and our continued ability to gain market share both organically and through acquisitions.
Gross margin expanded by 220 basis points to 32.8% in the second quarter as we continue to benefit from our operational improvements, primarily in pricing and category management. We are still in the early innings, and we'll continue to see benefits from our commercial and operational initiatives for the next several years.
Adjusted EBITDA increased by 12% to $74.9 million, and margin increased by 80 basis points to 14.6%. For the first 6 months of the year, we generated adjusted EBITDA growth of 30%.
Lastly, we continue to execute our acquisition strategy with the addition of Blue Max Materials in the Carolinas in April, and Bissett in Long Island, New York, earlier this month, which provide us with leading positions in their respective markets.
With that, I will now turn the call over to John to walk through the financials in more detail.
