"In the third quarter, we completed our executive team, signed with Fujitsu as our third major structured/platform ASIC development partner, and sold our first few licenses of Synplify DSP,” said Gary Meyers, President and CEO. “Despite softness in the overall EDA market and a significant increase in the level of our time-based business, we achieved double-digit revenue growth year over year, and with careful expense management, we had our most profitable quarter in over three years. I am pleased with our progress and excited to be in this new role,” Meyers concluded.

Use of Non-GAAP Financial Measures
This press release includes financial measures for net income (loss) and net income (loss) per share that exclude certain non-cash charges and that have not been calculated in accordance with GAAP. These measures differ from GAAP in that they exclude the amortization of intangible assets from acquisitions and stock-based compensation expense for stock options granted prior to Synplicity’s initial public offering. Synplicity has previously provided these measurements in addition to GAAP financial results because it believes they provide a consistent basis for comparison between quarters that is not influenced by certain non-cash expenses and therefore are helpful to understanding Synplicity’s underlying operational results. Further, these non-GAAP measures are some of the primary measures Synplicity’s management uses for planning and forecasting. These measures should not be considered an alternative to GAAP, and these non-GAAP measures may not be comparable to information provided by other companies.
