Synopsys, Inc. (NASDAQ: SNPS) delivered 42% year-over-year revenue growth in its fiscal third quarter and raised full-year guidance, but separating the contribution from Ansys reveals a much more measured growth rate underneath the enlarged company. Synopsys, Inc. now expects fiscal 2026 revenue of approximately $9.715 billion at the midpoint, of which $2.98 billion is expected to come from Ansys products. That means Ansys is set to represent roughly 30.7% of total annual revenue.
The comparison with fiscal 2025 is more revealing. Synopsys, Inc. generated $7.054 billion of revenue last year, including $756.6 million from Ansys following completion of the acquisition on July 17, 2025. Removing that contribution leaves approximately $6.298 billion attributable to the rest of Synopsys, Inc.’s fiscal 2025 business.
For fiscal 2026, subtracting the expected $2.98 billion Ansys contribution from the $9.715 billion guidance midpoint leaves about $6.735 billion. On that mechanical basis, revenue outside Ansys is increasing by approximately 6.9%, far below the roughly 37.7% growth implied by total company guidance.
How much of Synopsys, Inc.’s FY26 growth is really coming from Ansys?
The arithmetic shows how rapidly the acquisition has changed Synopsys, Inc.’s financial profile. Total revenue is expected to increase by approximately $2.661 billion between fiscal 2025 and fiscal 2026. Over the same comparison, Ansys revenue rises by about $2.223 billion as Synopsys, Inc. moves from owning the business for only part of fiscal 2025 to including it throughout fiscal 2026.
That means increased Ansys revenue mechanically accounts for about 83.6% of the absolute year-over-year increase in Synopsys, Inc.’s revenue.
The calculation does not mean the legacy Synopsys business is weak. Management said electronic design automation demand remains strong and expects double-digit EDA growth, while Design IP returned to year-over-year expansion during Q3. It does mean investors should be careful about interpreting the consolidated 38% full-year growth rate as though the entire existing business suddenly accelerated to that level.
There is also a divestiture complication. Fiscal 2026 guidance reflects approximately $110 million of revenue impact from the divested Optical Solutions Group and PowerArtist RTL businesses plus another $40 million associated with the Processor IP Solutions divestiture. Adding those amounts back purely as an illustrative adjustment would push ex-Ansys growth toward roughly 9%, although timing and portfolio differences mean that figure should not be treated as formal organic-growth guidance.
Why did Design Automation jump 53% while Design IP grew only 11%?
The segment numbers reinforce the acquisition effect. Design Automation revenue reached $2.003 billion in Q3, up from $1.312 billion a year earlier, representing growth of approximately 52.7%. That segment now includes Ansys products alongside Synopsys, Inc.’s traditional electronic design automation and system-design offerings.
Design IP revenue increased much more moderately from $427.6 million to $473.8 million, or about 10.8%. Yet that result was strategically important because the business had previously been an area of concern, and management specifically highlighted its return to year-over-year growth.
Design Automation also generated a 45.2% adjusted operating margin during Q3, compared with 26.5% for Design IP. The acquisition therefore is not merely inflating revenue. The enlarged Design Automation operation is producing substantial segment profitability as integration progresses.
The challenge for Synopsys, Inc. is increasingly to prove that combining engineering simulation with chip-design software creates additional organic growth rather than simply making the reported company larger.
Is the Ansys acquisition also improving cash generation?
This is where the latest guidance becomes particularly constructive. Synopsys, Inc. raised its fiscal 2026 free cash flow forecast to approximately $2.6 billion from roughly $2.0 billion previously, while expected operating cash flow increased to about $2.8 billion. Capital expenditure is now expected near $225 million.
The $600 million increase in free cash flow guidance matters because large acquisitions can produce impressive revenue growth while consuming cash through integration, restructuring and financing costs. Synopsys, Inc. has incurred substantial acquisition-related amortization, with amortization of acquired intangible assets reaching $1.21 billion during the first nine months of fiscal 2026 compared with only $99.2 million a year earlier.
That explains part of the unusually wide gap between GAAP and adjusted profitability. Q3 GAAP operating income was $357.5 million, while total adjusted segment operating income reached approximately $1.03 billion. Investors therefore need to monitor both the underlying operating economics and the very real accounting and integration costs created by the transaction.
Why does acquisition-adjusted growth matter after SNPS jumped 13%?
Synopsys, Inc. shares closed August 27 at $464.89, surging 13.39% after the earnings beat and raised outlook. The stock remained well below its 52-week high of $615.79 despite the rally, showing that investors are beginning to rebuild confidence after earlier concerns around Design IP performance and integration execution.
The market’s enthusiasm has solid foundations. Q3 revenue exceeded guidance, non-GAAP earnings per share reached $3.91, Design Automation remained strong and management lifted full-year revenue, margin, earnings and cash-flow expectations.
But the sharper Quick Hit is that Synopsys, Inc. is currently two growth stories layered on top of each other. Consolidated fiscal 2026 revenue is heading toward approximately $9.72 billion, almost 38% above fiscal 2025. Yet nearly $3 billion of that revenue comes from Ansys, and the increase in Ansys contribution mathematically explains roughly 84% of the absolute year-over-year revenue gain.
That does not weaken the acquisition thesis. It clarifies the next test. Once the year-over-year benefit from consolidating Ansys begins normalizing, Synopsys, Inc. will need the combined platform to demonstrate that artificial-intelligence-driven EDA demand, simulation cross-selling and Design IP recovery can sustain strong growth without relying on acquisition arithmetic.
