Cadence Design Systems Q3 2026: revenue up 22% to $1.63B, but GAAP EPS flat at $1.05 on Hexagon costs

Cadence Design Systems sells the software (and some specialised hardware) that chip designers use to lay out, simulate and test semiconductors, plus licensed chip building blocks ("IP") and simulation tools for whole electronic systems. In the quarter ended September 30, 2026, revenue rose 22% to $1,633.3 million. Profit did not follow: GAAP net income was $289.7 million, up 0.9%, and GAAP diluted EPS was $1.05, exactly the same as a year ago. The gap comes from three things: the cost of owning the Hexagon design-and-engineering business Cadence bought in February, a $42.2 million restructuring charge, and a higher tax rate. Management still raised its full-year forecast for the third time this year, to about 21% revenue growth.

This analysis is written from the October 26, 2026 earnings release and CFO commentary (8-K Exhibits 99.01 and 99.02). The full 10-Q isn't filed yet, so the management discussion that would explain the restructuring charge, the split between acquired and organic growth, and revenue by country in dollars is not available yet.

Key figures

Operating margin is the share of revenue left after running the business, before interest and tax. Cadence's "non-GAAP" figures leave out stock-based pay, amortization of acquired intangibles, acquisition and integration costs, restructuring and a few investment and currency items. Backlog is revenue already under contract but not yet recognized.

Nine months to September 30: revenue was $4,692.0M (+21.7%). GAAP net income was $992.5M (+37.7%) and diluted EPS $3.61 vs $2.64, but the year-to-date comparison is flattered by the $128.5M export-control settlement charge booked in Q2 2025.

Where the growth came from

Cadence reports its product groups only as a share of revenue; the growth rates below are from the earnings release.

• Core EDA (+20%). EDA is "electronic design automation", the software category where Cadence's main rival is Synopsys. The release cites 16 new digital and signoff "full-flow wins" and growing use by memory makers and hyperscalers (the big cloud operators that now design their own chips). Hardware, meaning the emulation systems chip designers use to test a design before it is manufactured, had "another record quarter".
• IP (+24%). Demand for interface, memory and foundation IP from hyperscalers, chip companies and foundries. IP revenue is mostly booked when delivered, so it swings from quarter to quarter.
• SD&A (+30%) is partly bought growth. It includes the Hexagon design-and-engineering business, acquired on February 23, 2026, which wasn't in the Q3 2025 figures. The release doesn't separate acquired from organic growth, so 30% overstates how fast the pre-existing business grew.

By region, the Americas held at 43% of revenue and China slipped to 16% from 18%. On those rounded shares, China revenue rose only about 8% to roughly $261M. That is not weakness: Q3 2025 was the quarter China sales rebounded after the US briefly required export licences for EDA software between May and July 2025, so the comparison base is high.

Mix shifted toward one-time sales. Recurring revenue (software licences recognized over time, maintenance and royalties) was 79% of the quarter, down from 82%, and up-front revenue (hardware and IP booked on delivery) rose to 21% from 18%. Up-front sales are less predictable, which matters when judging how repeatable a beat is.

Why profit stood still

Total GAAP costs rose 31.9% to $1,204.6M against revenue growth of 22.0%. The income statement shows where:

• Acquisition amortization tripled. When a company buys another, part of the price is recorded as intangible assets (technology, customer relationships) and written off as an expense over several years. That expense was $79.9M this quarter, up from $26.0M, mostly from Hexagon. It is non-cash, but it reflects a real price Cadence paid.
• Restructuring of $42.2M, up from $27.4M a year earlier. The release gives no detail on what it covers; the 10-Q should.
• Operating spending grew faster than revenue. R&D rose 27% to $537.5M, marketing and sales 26% to $242.5M, and general and administrative 45% to $113.0M. Part of this is Hexagon's staff, and part is stock-based pay, which rose to $144.8M from $116.1M.
• Gross margin dipped to 85.6% from 86.4% (gross margin is revenue minus the direct cost of what was sold, as a share of revenue), as cost of product and maintenance rose 46% to $173.9M, which includes part of the amortization.

Below the operating line, other income was +$10.0M against -$3.6M a year ago (the prior year included an $18.6M loss on a currency hedge tied to an acquisition), so pretax income rose 4.0% to $408.3M. The effective tax rate then rose to 29.0% from 26.9%, which erased most of that gain.

Takeaway: Cadence's demand is strong: 22% revenue growth, every product group up 20%+, a record $8.2B backlog and a third guidance raise. But nine months after the Hexagon deal, the acquisition is still adding costs faster than revenue: GAAP operating margin fell 5.6 points to 26.2%, and even the non-GAAP margin, which strips out amortization and deal costs, fell 3.5 points. Revenue growth is not yet turning into profit growth.

What the headline numbers hide

• Cash conversion is good. Operating cash flow was $424M, 1.46 times GAAP net income, and $1,414M for nine months (1.43 times). Free cash flow (operating cash flow minus capital spending) was $362M vs $277M a year ago. Non-cash charges such as stock-based pay and amortization explain most of the difference between cash and profit.
• The GAAP-to-non-GAAP gap is wide and widening. Non-GAAP net income was $582.2M, about twice GAAP's $289.7M, and non-GAAP EPS of $2.11 is $1.06 above GAAP's $1.05 (a year ago the gap was $0.88). The excluded items, per share: stock-based pay $0.53, amortization $0.29, restructuring $0.15 and acquisition costs $0.09. Stock-based pay is a recurring cost of paying staff, not a one-off; it was 8.9% of revenue, and Cadence expects about 9% for the full year.
• One-offs in both years. This quarter's $42.2M restructuring charge is the main one. Setting restructuring aside in both years, pretax income would have grown about 7% rather than 4%. The prior year carried an $18.6M hedge loss that didn't recur, which helps this year's comparison.
• Receivables and inventory are growing faster than sales. Inventory rose 48% in nine months to $448.8M, and the cash flow statement shows $172.9M absorbed by inventory year to date, consistent with the record hardware demand. Receivables rose 17.5% since December to $1,110.6M, and days sales outstanding (how long customers take to pay, on average) were 66 against 55 a year ago. The release doesn't say how much of either came with Hexagon.
• Buybacks are not driving EPS. Cadence spent $400M on buybacks in the quarter (double the ~$200M it guided to in July) and $800M year to date, and the board added $2.5B to the authorization. Diluted shares still rose 0.5% to 275.3M, because the 3.2 million shares issued to Hexagon's seller outweigh the repurchases. Cadence pays no dividend.
• Guidance moved, but GAAP EPS guidance barely did. Full-year non-GAAP EPS guidance rose $0.30 at the midpoint, while GAAP EPS guidance rose only $0.06, and the full-year GAAP tax rate assumption moved up to about 27% from about 26%.

On balance the quarter is understated: GAAP EPS was flat, but the $42.2M restructuring charge and a higher tax rate held it back, and non-GAAP EPS rose 9.3%. Even that underlying figure grew well below the 22% revenue growth, so the acquisition's costs are real, not just an accounting effect.

Did last time's read hold up?

Our Q2 2026 report named three things to watch. Whether Hexagon's revenue starts to catch up with the costs it adds: not yet. GAAP operating margin fell further, from 28.4% in Q2 to 26.2%, and the non-GAAP margin from 45.5% to 44.1%. Whether IP and hardware deliveries keep pace: yes. IP grew 24%, hardware had another record quarter, and up-front revenue held at 21% of the total. China and the BIS 50%-ownership rule, whose suspension expires November 9, 2026: the release doesn't address it, and China's share of revenue rose to 16% from 15% in Q2. Cadence beat its own Q3 revenue guidance but came in below its $1.11–$1.17 GAAP EPS guidance.

Guidance and outlook

Management raised its full-year 2026 outlook again (CFO commentary):

For Q4 2026, Cadence guides to revenue of $1,695M–$1,725M (18–20% growth), GAAP EPS of $1.23–$1.29 (vs $1.42 in Q4 2025), non-GAAP EPS of $2.19–$2.25 (vs $1.99), and about $400M of buybacks. The share of 2026 revenue expected to come from backlog held at the start of the year is now about 64%, down from about 65% in July and about 69% for 2025, so a slightly larger part of the forecast depends on business signed during the year.

Our read: The revenue outlook looks well supported: Cadence has beaten its own revenue guidance and raised the year three times, and the backlog keeps growing. The profit picture is weaker than the headline guidance raise suggests. The Q4 guide implies GAAP EPS down 9–13% year over year even as revenue grows about 19%, and the GAAP operating margin of 30–31% would still be below Q4 2025's 32.2%. The figure to watch in 2027 is the non-GAAP operating margin. It rose every year from 37.2% in 2021 to 44.6% in 2025, and the 2026 guidance midpoint of 44.7% means that climb has stalled in the deal's first year. If it resumes in 2027, the acquisition costs were mostly an integration problem; if it doesn't, the purchase has slowed Cadence's profit growth for longer. Also watch whether inventory and receivables keep growing faster than sales, and the November 9 BIS rule date for China.
