Free cash flow margin finished at 21.1%, down YoY.
Operating cash flow
Operating cash flow declined 5.1% YoY despite stronger earnings.
R&D expense
R&D up 13.3% YoY to support technology inflections.
Capital returns
Capital returns totaled $3.85B while management emphasized discipline.
AI transformation shifted the year from “risk framing” (China/tariffs) to “execution proof” (tool maturity, served-market share) while cash flow required close monitoring.
Technology intensity
Across Q1 through Q4, management tied strength to AI-led transitions that increase deposition and etch intensity—particularly as devices scale and packaging complexity rises. They repeatedly highlighted new and upgraded tool capabilities as the mechanism to convert that intensity into served-market share and outperformance.

| Theme | Q1 | Q2 | Q3 | Q4 | Next monitor |
|---|---|---|---|---|---|
| AI-led process intensity translating into served-market share | Positive Management linked AI demand to real equipment needs and served-market expansion. |
FY2026 improvements centered on scaling AI-led technology transitions into tool and service share; the main challenge was sustaining cash conversion and managing China/mix sensitivity under constraints.
In Q3 Q&A, management attributed strong gross margin resilience to operational proximity, supply-chain setup, and ensuring new tools reach maturity for fast ramps in constrained periods.
Management linked CSBG strength to spares, upgrades, and services, then expanded the monetization story around predictive maintenance and Dextro cobots improving uptime/yield and efficiency.
Management raised WFE expectations by Q3 to $140B with upside bias and framed SAM as expanding toward slightly above mid-30s in 2026.
Across Q1–Q3 the investor story moved from quantified China/policy and AI build-out framing to evidence of stronger momentum; by Q4 it concludes the year’s execution proof and sets the next momentum backdrop.
Profitability scaled, cash flow softened
FY2026 began with strong AI-led demand proof but explicit China policy/mix headwinds; mid-year turned toward clean-room constrained execution and second-half weighting; by Q3, management reinforced momentum with an increased WFE outlook and deeper NAND conversion pull-forward.
Management highlighted record quarter execution while explicitly modeling affiliate-rule exposure and expecting China to represent under 30% of revenues in calendar 2026. AI demand was framed as translating into real near-term equipment needs.
Read earnings transcriptManagement said 2025 delivered record top and bottom line results and that 2026 WFE should be constrained by clean-room space and second-half weighted. They also pointed to advancing gate-all-around, HBM, and NAND demand with new product momentum.
These watch items reflect the recurring uncertainties and management focus areas that could affect next-year estimates and risk framing.
They shape WFE timing and revenue sequencing, affecting how guidance translates into quarter-by-quarter results.
Track management’s WFE outlook language, references to sold-out conditions, and any updated commentary on how much execution fits the year.
China policy and mix dynamics influence gross margin, down payments, and revenue composition despite overall demand.
Monitor “China flattish” statements, updates to China revenue share expectations, and how gross margin is attributed to customer mix.
In Q1, management quantified affiliate-rule exposure and framed China as set to be less than 30% of revenue in calendar 2026. By Q2 and Q3, China became described as flattish year-over-year with global multinationals offsetting declines, while down payments and gross margin headwinds were attributed to mix rather than collapses.
Capacity constraints
From Q2 onward, management emphasized that WFE and end-market build-outs were constrained by clean room space, with sold-out dynamics and multiyear agreements. They described 2026 as second-half weighted, while still expecting growth quarter by quarter as customers pulled in some orders and worked within existing fabs.
Services monetization
Across multiple calls, management described Customer Support Business Group strength as tied to spares, upgrades, and services—supported by higher utilization and increasingly advanced tooling help. By Q2 and Q3, they added that equipment intelligence and Dextro cobots support productivity/yield and can improve how CSBG monetizes the installed base during constrained periods.

| Gross margin resilience versus mix headwinds and tariff effects | Mixed Gross margin benefited from mix but management expected tariff headwind increasing. | Positive December gross margin exceeded guidance on better customer mix. | Positive March quarter gross margin at high end despite mix headwinds guidance. | Watch management’s Q&A deconstruction of gross margin drivers: customer mix, tariffs, and factory efficiency self-help actions. |
By Q3, management expected most of the $40B NAND conversion to occur before end of calendar 2027, indicating faster upgrade execution than earlier guidance pace.
Structured financials show operating cash flow and free cash flow down year over year, signaling that working capital, capex timing, or other cash factors may have offset earnings gains.
Management repeatedly described China as a meaningful mix driver: quantifying the affiliate-rule impact in Q1 and later attributing gross margin and down-payment behavior to customer mix.
In Q2 and Q3, management discussed sold-out conditions and declined to quantify clean-room cost, emphasizing constraints can shift output timing into the second half.
Management emphasized upgrades as the primary path while clean-room space limits greenfield capacity additions, leaving sequencing and quarter-to-quarter variability a recurring theme.
