David Schaeffer
Management
Thank you, and good morning to everyone. Welcome to our Third Quarter 2012 Earnings Conference Call. I'm Dave Schaeffer, Cogent's Chief Executive Officer. With me on this morning's call is Tad Weed, our Chief Financial Officer.
We are pleased with our results for the quarter, and are optimistic about the strength of our business and the outlook for the remainder of 2012 and for the full year 2013. During the quarter, we experienced sequential revenue growth, EBITDA margin expansion, lower churn and a significant increase in traffic on our network. Additionally, we returned approximately $4.5 million to our shareholders on our first quarterly dividend of $0.10 a share that was paid in September. We continue to be confident in the cash flow generative capabilities of our business. As a result, and as we indicated in our press release, we announced a 10% increase in our quarterly dividend to $0.11 per share to be paid on December 12, 2012, to holders of record as of November 21, 2012.
On a constant currency basis, our revenue grew from the second quarter sequentially 2.8%. On a constant currency basis and adjusting for the loss of our largest customer in January 2012, Megaupload, our revenue growth on a year-over-year basis would have been 11.9% from the third quarter of 2011. Our EBITDA margin expanded by 30 basis points sequentially from the second quarter to 32.9%. Since absorbing the loss of Megaupload in the first quarter, our EBITDA margin has expanded in the past 2 quarters by 360 basis points. During the quarter, traffic growth on our network accelerated to 17% sequentially from the second quarter. And on a year-over-year basis, traffic grew 28% from the third quarter of 2011.
Since the end of second quarter, we continued to expand our footprint by adding an additional 33 buildings to our network. During the quarter, our sales rep productivity was 4.9 installed orders per rep per month. This is significantly above our historical average of 4.1 installed customer connections per rep per month.
Throughout this discussion, we will highlight several operational statistics we believe demonstrates our increasing market share, expanding scale and size of our network, and most importantly, the operating leverage of our business model. We continue to believe we have built a business with a significant barrier to entry anyone trying to replicate what we have assembled here at Cogent. We are the lowest cost most efficient operator in our sector. We remain focused on the most revenue-rich locations, which we then bring on at selling the highest quality Internet service to our customers at the absolute lowest price and best value in the market.
I will review in greater detail certain operational highlights and our continued expansion plans. Tad will provide some additional details on our financial performance. Following our remarks, we'll open the call for questions and answers.
Now I'd like to turn it over to Tad to read our Safe Harbor language.
