Thanks, Jack. I'll cover the financial results for the third quarter and our guidance for the fourth quarter and full year 2015.
Total revenue for the third quarter was $17.1 million, an increase of 5% from a year ago. And it was $18.1 million or 11% growth on a constant currency basis. When using the currency exchange rates from the second quarter of 2015 just a quarter ago, total revenue for the third quarter was $17.4 million.
Recurring revenue from subscription and support grew 14% year-over-year to $14.1 million or 20% growth on a constant currency basis. When using the currency exchange rates from the second quarter of 2015, again, just a quarter ago, recurring revenue for the third quarter was $14.4 million. Professional services revenue was $2.4 million for the quarter, down 20% year-over-year, and perpetual license revenue declined 36% year-over-year to $540,000.
Moving down the P&L to gross margin. Overall, gross margin was 62% during the third quarter, and our product gross margin remained strong at 67%, or 71% when adding back amortization of acquired intangible assets. Professional services gross margin was 31% during the third quarter.
Turning to our operating expenses. Research and development expense was $3.9 million for the third quarter, representing 23% of total revenue. Sales and marketing expense was $2.9 million, representing 17% of total revenue for the third quarter. General and administrative expense was $4.5 million in the third quarter, representing 26% of total revenue. Excluding -- but excluding noncash stock compensation for the third quarter, G&A expense was $3.9 million or 23% of total revenue.
Operating loss was $1.8 million in the third quarter of 2015, compared to a loss of $1.7 million in the same quarter of 2014. GAAP net loss was $2.3 million or a loss of $0.16 per diluted share, compared to GAAP net loss of $2.4 million or a loss of $0.80 per diluted share in the third quarter of 2014. And GAAP net loss was $3.3 million or a loss of $0.22 per share in the second quarter of 2015.
Non-GAAP net income was $27,000 or breakeven per diluted share, compared to non-GAAP net loss of $0.9 million or a loss of $0.25 per share -- per diluted share in the third quarter of 2014.
Our third quarter 2015 adjusted EBITDA was $1.1 million, compared to $550,000 in the third quarter of 2014, representing year-over-year growth of 94%. And $670,000 in the second quarter of 2015, representing quarterly sequential growth of 58%.
Now on our -- on to our balance sheet and statement of cash flows. We ended the third quarter with $28.7 million in cash, compared to $29.1 million at the end of the second quarter of 2015. Cash flows from operating activities were a positive $2.2 million for the trailing 12 months ended September 30, 2015, compared to a positive $600,000 for the trailing 12 months for the period ended September 30, 2014.
Now I want to cover Q4 and full year 2015 guidance. For the quarter ended December 31, 2015, Upland's year-over-year constant currency total revenue guidance is in the range of $17.6 million to $18.6 million or growth of 10% at the midpoint over the quarter ended December 31, 2014. And reported total revenue guidance is in the range of $16.6 million to $17.6 million or growth of 4% at the midpoint over the quarter ended December 31, 2014, based on third quarter 2015 foreign currency exchange rates. Adjusted EBITDA guidance for Q4 is in the range of $1.4 million to $2 million or adjusted EBITDA margin of 10% of total revenue at the midpoint.
For the full year ending December 31, 2015, Upland's constant currency total revenue guidance is in the range of $72.1 million to $73.1 million or growth of 12% at the midpoint over the full year ended December 31, 2014. And reported total revenue guidance is in the range of $68.9 million to $69.9 million or growth of 7% at the midpoint over the full year ended December 31, 2014.
For the full year ended December 31, 2015, Upland's adjusted EBITDA guidance to be in the range of $3.5 million to $4.1 million or adjusted EBITDA margin of 5% of total revenue at the midpoint.
With that, I'll turn the call over to Tim Mattox, our President and COO.
