Why Synopsys, Inc. (SNPS) Stock Rose 13.4% on Aug 27, 2026
The clearest new catalyst: Record fiscal Q3 beat (reported Aug 26, after close).

Why did SNPS stock rise?
Synopsys surged 13.39% to $464.89 on Thursday, August 27, 2026 after its fiscal Q3 results, released after Wednesday's close, topped expectations and prompted a higher full-year outlook. Revenue rose 42% to a record $2.477 billion and non-GAAP EPS reached $3.91, while management cited strength in EDA, a solid contribution from the Ansys acquisition and continued AI-driven engineering demand; backlog remained robust at $10.9 billion.
- Record fiscal Q3 beat (reported Aug 26, after close): Synopsys posted non-GAAP EPS of $3.91 (up ~15% YoY, versus ~$3.67 consensus) and GAAP EPS of $2.84, on record revenue of $2.477 billion (up 42% YoY, a beat of about $40 million). Because the results came after Wednesday's close, Thursday, August 27 was the first full regular session reacting to the report.
- EDA strength, AI-chip demand and Ansys: Growth was led by Design Automation (EDA) outperformance and AI-driven silicon/engineering demand, plus the Ansys acquisition — but note the 42% growth is not all organic: Ansys contributed roughly $711 million of Q3 revenue, so part of the surge reflects the deal. Backlog stood at $10.9 billion.
- Raised full-year guidance: Synopsys lifted its FY2026 outlook to revenue of about $9.690-9.740 billion (midpoint $9.715B) and non-GAAP EPS of $15.04-15.10, with Q4 revenue targeted at $2.530-2.580 billion.

What it could mean for SNPS investors
The constructive case
- A record quarter with a 42% revenue jump and a $10.9B backlog underscores Synopsys's central role in AI-driven chip design (EDA) and simulation (Ansys).
- Raising both revenue and EPS guidance signals confidence in continued demand through the back half of the fiscal year.
The cautious case & what could invalidate it
- Part of the 42% growth reflects the Ansys acquisition (about $711M of Q3 revenue) rather than pure organic demand — a factor to watch as the deal laps.
- After a sharp one-day re-rating, the shares carry elevated expectations against the raised guidance.
- EDA/AI-chip demand is tied to the semiconductor capex cycle, which can turn.
