PITTSBURGH – August 24, 2010 – ANSYS (NASDAQ: ANSS) has been ranked number 39 on the 2010 FORTUNE 100 Fastest-Growing Companies list. The ranking includes ANSYS as the sole provider of product development software, a recognition that underscores the strategic value of engineering simulation as well as the ANSYS leadership position in this growing and critical market. This is the second consecutive year that ANSYS has been included in the elite FORTUNE grouping.

To qualify for 100 Fastest-Growing Companies, foreign or domestic organizations had to meet the following criteria: be trading on a major U.S. stock exchange; file quarterly reports with the SEC; have a minimum market capitalization of $250 million and a stock price of at least $5 on June 30, 2010; and have been trading continuously since June 30, 2007. The company must also have revenue and net income of at least $50 million and $10 million, respectively, for the four quarters ended on or before April 30, 2010. Finally, the company must have posted an annualized growth in revenue and earnings per share of at least 15 percent annually over the three years ended on or before April 30, 2010. Companies that met these criteria were ranked by revenue growth rate; EPS growth rate; and three-year annualized total return for the period ended June 30, 2010.

“In the current economy, organizations need to launch superior products quickly under competitive, cost and regulatory pressures,” said Jim Cashman, president and CEO of ANSYS. “The fundamental value of ANSYS engineering simulation software is not in doing what you did yesterday 10 percent more effectively; it’s in terms of being able to do things in completely different ways, breaking the status quo, jumping to that next curve. Business as usual is not an option.”

ANSYS makes engineering simulation software that companies can use early on in the development process to predict how well a design might function and behave in the real world. Engineers and designers in a wide array of industries — including automotive, aerospace, biomedical, defense and electronics — use its products to help minimize costs and reduce the amount of time it takes to rollout a finished product.
