The UK Competition and Markets Authority (CMA) announced on Friday that it has concluded its investigation into Synopsys' (SNPS.US) acquisition of Ansys. The CMA stated: "Following specific commitments made to avoid a formal investigation, the divestment of relevant assets was fully completed on October 17, 2025. This marks the end of the merger inquiry."

Synopsys finalized its acquisition of Ansys on July 17, 2025, in a deal valued at approximately $35 billion. The transaction aims to merge the electronic design automation (EDA) leader with the simulation software giant, creating a comprehensive solutions provider spanning chip design to system design.

However, the deal faced rigorous antitrust scrutiny from regulators worldwide due to the involvement of two leading technology firms. To address competition concerns in markets like the UK, Synopsys and Ansys agreed to divest certain businesses. Synopsys sold its optical software tools and photonics software operations, while Ansys divested its PowerArtist power analysis tool. These assets were acquired by Keysight Technologies (KEYS.US), which completed the purchase in October 2025.
