Subject: Ansys Update

Dear Valued Partner,

I’m reaching out to share some exciting news – Ansys is combining with Synopsys, creating a leader in silicon to systems design solutions. Our announcement marks the beginning of an important next chapter for our two companies, and one that we believe will greatly benefit our many customers around the world. You can read more here.

This combination is a natural next step for Ansys and Synopsys, as it builds on our successful and growing strategic partnership established in 2017. By bringing together our complementary businesses, we will create a powerful, comprehensive product portfolio and provide the foundation for customers’ most critical next-generation technology initiatives. This will enable us to help customers meet new goals for safety, price, functionality, reliability, and performance while providing engineers unprecedented insights into the performance of their products. We look forward to utilizing our respective strengths and capabilities to drive new levels of innovation.

While today’s announcement is an important milestone, it is only the first step in combining our two companies. We expect to close the transaction in the first half of 2025. Until then, Ansys and Synopsys will continue to operate as independent companies. This means it is business as usual at Ansys and there are no changes to how we work with you. Should you have any questions, please feel free to reach out to Andy Kincheloe, VP Global Marketing, Channel and GTM Operations or Ravi Kumar, Area VP Global Channel Sales.

On behalf of the entire Ansys team, I want to thank you for your partnership and trust. We look forward to continuing to help businesses solve many of today’s most complex engineering, software and technology challenges and empowering the innovations that are changing the way people work and play.

Sincerely,

Ajei Gopal

President and Chief Executive Officer
