Core Viewpoint - The Chinese regulatory authority has suspended the antitrust review of Synopsys' acquisition of Ansys, adding uncertainty to the deal amid escalating US-China technology tensions [1][2]. Group 1: Acquisition Details - Synopsys announced a final acquisition agreement with Ansys on January 16, 2024, with a total transaction value of approximately $35 billion, where Ansys shareholders are expected to hold about 16.5% of the new company post-merger [1]. - The merger is viewed as a "strong alliance," combining Synopsys' significant position in the EDA (Electronic Design Automation) sector with Ansys' expertise in industrial simulation software, which spans various industries including automotive, aerospace, and electronics [1]. Group 2: Regulatory Environment - The suspension of the antitrust review by Chinese regulators is seen as a cautious decision influenced by the US's recent export control measures targeting China's semiconductor industry, which has led Synopsys to halt sales and technical support activities in China [2]. - Analysts suggest that the Chinese regulatory stance is a response to US actions perceived as attempts to restrict China's chip design capabilities, indicating a need to maintain market competition and assert technological sovereignty [2]. Group 3: Global Antitrust Review Progress - Prior to the suspension, the UK's Competition and Markets Authority (CMA) and the European Commission expressed concerns that the merger could weaken competition in specific markets related to digital chip RTL power analysis software and optical software [3]. - To address these concerns, Synopsys and Ansys proposed several remedial measures, including divesting Ansys' RTL power analysis business and selling Synopsys' optical solutions group, which helped alleviate regulatory worries in Europe [3]. - Despite the ongoing uncertainties, 21 brokerages, including Berenberg, continue to maintain a "buy" rating for Synopsys, although the market remains cautious about the future of the transaction [3].
