ANSYS expects the acquisition to be immediately accretive to earnings, excluding acquisition-related costs, amortization of intangibles, the impact of deferred revenue purchase accounting treatment and expensing of stock options. The company used a combination of existing cash and proceeds from approximately $200 million of committed bank financing to fund the transaction.

Fluent Inc. is a global supplier of CAE simulation software technologies and services. Fluent products utilize computational fluid dynamics (CFD) principles and techniques to enable engineers and designers to simulate fluid flow, heat and mass transfer, and related phenomena involving turbulent, reacting, and multiphase flow. The company's products are used by blue chip companies, small and medium size enterprises, and academic institutions and institutes around the world. Today, CFD simulation technology is used in almost every industry sector and manufactured product.

"With the acquisition of Fluent, ANSYS has significantly broadened its offerings in the simulation market. I expect ANSYS to be an important partner to design engineers in industries, from discrete manufacturing, oil and gas, chemicals, food processing, as well as to environmental scientists studying how pollution propagates and oceanographers trying to predict the effects of global warming. Ships, airplanes, cars, your PC, home, office building and the environment -- all will work better, be more efficient, pollute less or be better managed as a result of a better understanding of the dynamics of the gases and liquids in which, and with which, they operate," commented Daratech CEO Charles M. Foundyller.

Jim Cashman, ANSYS President and CEO added, "Finalizing the acquisition of Fluent is great news for us, our customers and partners. We are very excited to be able to move forward today as a unified company and begin executing our strategy for the future."

"With the operations and technology synergies that Fluent and ANSYS share, we are confident that we can meet the needs of the CAE community for simulation software and services in a highly effective manner," said Dr. Ferit Boysan, Vice President and General Manager, Fluids Business Unit.

The combination of ANSYS' and Fluent's software products and services is expected to give ANSYS one of the most comprehensive, independent engineering simulation software offerings in the industry, reaffirming and strengthening ANSYS' commitment to open interface and flexible simulation solutions that are primarily driven by customer demand and choice. With over 40 direct sales offices and 17 development centers, on three continents, the combined company will employ approximately 1,350 people.

The company expects to provide updated financial guidance with respect to Fluent and the financial outlook of the combined company in the next couple of weeks.
