Synopsys reports quarterly revenue below estimates, shares fall

Synopsys (SNPS) reported third-quarter revenue of $1.74 billion and adjusted EPS of $3.39, missing analyst estimates of $1.77 billion and $3.74, respectively, which led to a 20% premarket share decline. The underperformance was primarily attributed to weakness in its Design IP business, stemming from new export restrictions impacting China design starts and the withdrawal of a major foundry customer. Despite the Q3 miss, Synopsys projected current-quarter revenue between $2.23 billion and $2.26 billion, exceeding analyst expectations of $2.09 billion, indicating a mixed near-term outlook.

Analysis

Synopsys (SNPS) reported a significant miss for its third quarter, with revenue of $1.74 billion and adjusted earnings of $3.39 per share falling short of consensus estimates of $1.77 billion and $3.74, respectively. This underperformance triggered a severe market reaction, with shares declining 20% in premarket trading. The primary driver for the miss was pronounced weakness in the Design IP business, which CEO Sassine Ghazi attributed to two distinct factors: the failure of deals to close due to new export restrictions disrupting design activity in China, and the unexpected withdrawal of a major foundry customer. The loss of this customer is particularly impactful as Synopsys had already made significant investments anticipating returns in the second half of 2025. In a conflicting signal, however, the company issued strong current-quarter revenue guidance of $2.23 billion to $2.26 billion, well above the $2.09 billion analyst forecast. This guidance comes just after the July completion of its $35 billion acquisition of Ansys and contrasts with rival Cadence Design Systems, which recently raised its own annual forecast, suggesting Synopsys's headwinds may be idiosyncratic.

Key Decisions for Investors

• Investors should treat the 20% share price decline as a reflection of significant new risks, primarily the financial impact of the lost foundry customer and persistent uncertainty surrounding the China business, which have clouded the outlook for the high-margin Design IP segment.
• The substantially stronger-than-expected Q4 revenue guidance creates a dichotomous narrative; this may present a strategic entry point for investors with a high-risk tolerance who believe the Q3 issues are contained and that the Ansys acquisition will drive immediate top-line growth.
• Given that rival Cadence raised its forecast, Synopsys's challenges appear company-specific, meaning successful execution and synergy realization from the massive Ansys integration are now paramount to offsetting the core business weakness and justifying the optimistic forward guidance.
