Thank you, Sarah. Good morning, everyone. Thank you for joining our conference call and your continued interest in Thermon. Today, we will have 2 of our senior vice presidents joining us on the call. Jay Peterson, our CFO, will follow me and present the financial details of our FY 2013 third quarter and year-to-date results; George Alexander, our Executive Vice President of Global Sales, will assist in the Q&A session by answering questions that pertain to global market segments and industry trends.
For those of you who are not familiar with Thermon, we are a leading global provider of thermal solutions. We serve the oil, gas, chemical and power generation industries. Our heat tracing systems provide freeze protection and temperature control for piping, vessels and instrumentation. These mission-critical systems ensure the continuous and safe operation of industrial facilities.
While Jay will discuss the financial details in a moment, I would like to touch on some of the highlights of the quarter.
Our Q3 revenue was the highest in our history. Our operations, engineering and construction personnel did an outstanding job of getting their work done in the quarter with 2 major holidays. We are very proud of this achievement.
Our revenue for Q3 was approximately $77 million, which is an increase of 11% over prior year's Q3. Our revenue mix for the quarter was 42% greenfield projects and 58% MRO/UE business. Our total gross profit was $35 million, which is another all-time high for Thermon. Margins were at 45.5% of sales, which compares to 48.7% of prior year's Q3. While the margins were slightly lower than the previous 2 quarters, they're still consistent with our historical average of approximately 45% of sales.
Our Q3 backlog remained strong at $107 million versus prior year's quarter of $102 million. We have now completed our new control panel and skid fabrication facility at our San Marcos, Texas plant. We have also completed our move to our new office in Houston, Texas. This has more than doubled our engineering workspace. These 2 infrastructure buildouts, combined with the recently completed wire manufacturing facility in San Marcos, has put us in an excellent position to accommodate future growth. Our global footprint continues to penetrate our targeted end-markets which are: oil, gas, power and chemical, thus, resulting in continued long-term organic growth. We are very excited about our record-breaking year. We have grown our business despite unfavorable foreign currency headwinds that Jay will touch on in a little bit.
Our management team would like to thank our employees throughout our global organization for their hard work and dedication. We would also like to thank our customers, investors and advisors for their support and confidence. Thank you, again, for joining us today.
Jay Peterson, our Chief Financial Officer, will now address the details of financial performance for Q3 and FY 2013 year-to-date.
