Product lifecycle management software vendor PTC has reported revenues of $269.2m for the second quarter of 2011, an increase of 12%compared to $240.6m in the same quarter previous year.

The company registered an increase of 110.4% in operating income to $24.2m compared to $11.5m for the second quarter of fiscal 2011.

For the second quarter ended 2 April 2011, the net income of the company increased to $19.1m compared to $9.1m in the previous year quarter and diluted EPS increased to $0.16 compared to $0.08 in the year-ago quarter.

PTC president and CEO James Heppelmann said the company had a strong Q2, with revenue and EPS at the high-end of their guidance range. Their license revenue of $74.2m was up 15% on a year-over-year basis, and included 40% year-over-year growth in Desktop license revenue.

"This was our 5th consecutive quarter of year-over-year improvement in Desktop license revenue and in our Channel business. Our Enterprise license revenue was down 15% year-over-year, and was significantly impacted by lower than expected Federal, Aerospace & Defense revenue in North America, and the dilutive effect of the strong Desktop revenue on PLM sales capacity," Heppelmann said.

For the third quarter of 2011, the company expects revenue to range between $275m and $285m and EPS between $0.16 and $0.20.
