Synopsys closed its roughly $35 billion Ansys acquisition — the largest deal in its history — in the same quarter that China export controls, a major foundry customer's slowdown, and the company's own admitted execution mistakes forced a guidance cut and a 10% workforce reduction. Two years later, results are recovering, but confidence hasn't yet returned to where it stood before the crisis.
The story
2023: a stable three-segment leader
Through 2023, Synopsys was a steady EDA leader with three segments — Design Automation, Design IP, and Software Integrity (security/quality software) — each posting double-digit growth, with "another record revenue" repeated on nearly every earnings call. In January 2024, Sassine Ghazi became CEO, and that same year the company announced it would acquire engineering-simulation software maker Ansys for roughly $35 billion — the largest deal in company history, and in the engineering-software industry's history.
Reshaping itself to close the deal
Closing a deal this size required real restructuring. The FY2024 10-K's business description dropped from three segments to two — Software Integrity had been sold off entirely. At the same time, a brand-new risk category appeared: "Risks Related to the Ansys Merger," warning of a termination fee of up to $1.5 billion if the deal fell through, and flagging that significant new debt would follow. Early-2025 calls repeatedly said China would "slow to company-average levels" — language that, quarter by quarter, crept toward "below company average."
Everything hit at once
The real turning point came in Q3 FY2025 (September 2025). Just three months earlier, the company had said it had "received no notification from BIS" and held its annual guidance. This quarter, it confirmed an actual six-week China export restriction had hit, layered on top of a major foundry customer's demand slowdown — and, unusually, management admitted in its own 10-K that "some of our roadmap and resource allocation decisions did not yield their intended results." Annual guidance was cut and a 10% workforce reduction was announced. All of this landed in the same quarter the Ansys deal finally closed (July 2025) — integrating history's largest deal while one of its core businesses was cracking.
A slow, still-incomplete recovery
Q4 FY2025 (December 2025) results beat the lowered guidance's top end slightly, but full-year China revenue finished down 18% (down 22% excluding Ansys) — far from the "company average" pace promised a year earlier. FY2026 guidance explicitly stated the company would "remain cautious on China." Q1 and Q2 FY2026 each beat guidance's top end, and Q2 raised revenue, margin, EPS, and free-cash-flow guidance all at once, with management saying Design IP had "bottomed in Q1 and recovery is beginning."
Guidance scorecard
| When set | What was promised | What actually happened | Result |
|---|---|---|---|
| Q4 FY2024 → FY2025 | China to slow to "company-average" pace; double-digit revenue growth | China revenue -18% for the year; guidance itself was cut mid-year | Missed |
| Q2 FY2025 | "No notification from BIS," guidance held | Reversed just one quarter later when export restrictions actually hit | Reversed quickly |
| Q3 FY2025 (lowered) | FY2025 revenue $7.00B–$7.03B | Actual $7.05B; Q4 EPS slightly above guidance | Met (against lowered bar) |
| Q4 FY2025 → FY2026 | Revenue $9.56B–$9.66B | Q1 FY2026 beat the top end; EPS raised $0.06 | Beat |
| Q1 FY2026 (reaffirmed) | Full-year revenue/margin/cash-flow guidance held | Q2 FY2026 beat; revenue, margin, EPS, and FCF guidance all raised | Beat |
4 of 5 tracked promises met or beaten; 1 (the China revenue outlook) clearly missed. Quarterly revenue and EPS guidance itself follows a fairly typical conservative-then-slight-beat pattern — but the China and export-control outlook specifically showed a repeated optimism-then-walk-back pattern.

Our read
The real story of these two years isn't simply "the merger closed" — it's that a historic acquisition and a genuine crisis in the core China/foundry business happened to collide in the same quarter, testing management's crisis-handling under maximum pressure. The last two quarters' guidance raises are clearly positive, but whether "recovery" reflects real demand improvement or just an easier year-over-year comparison base is something only the next two or three quarters can really confirm.
What we still don't know
- The specific reasons behind the company's own admitted "roadmap and resource allocation" mistakes aren't detailed anywhere in the filings reviewed here.
- Concrete progress on Ansys integration synergies (cost savings, cross-selling) would require the company's planned September 2026 Investor Day materials, outside this analysis's scope.
- Whether China export controls will expand further or stabilize is a policy variable the company's own disclosures can't predict.
