Japan semiconductor equipment May billings +11% YoY, WFE upcycle continues

Overview

This report is Bernstein’s monthly data tracking of the global semiconductor capital equipment industry, primarily based on billing data published by SEAJ for Japanese semiconductor equipment suppliers. SEAJ members represent about 25% of the global wafer fab equipment market, so this data serves as a high-frequency indicator for observing Japanese equipment makers and the global WFE cycle. May data continued to show YoY growth in Japanese SPE billings, and the 3-month moving average extended the cyclical uptrend that began in mid-CY2023.

Core views

The core view of the report is that Japanese equipment makers’ billings remain in a recovery and expansion phase, and the rebound in memory capex will drive continued global WFE growth in CY2026 and CY2027; Japanese equipment companies as a whole are positioned to benefit from investment in DRAM, NAND, HBM, advanced packaging, and advanced logic. At the company level, there is near-term divergence: SEAJ front-end equipment data suggests Tokyo Electron’s June quarter may come in below consensus, while testing equipment data suggests Advantest may come in above consensus.

Analysis framework

The report uses both single-month SEAJ billings and a 3-month moving average to observe trends: single-month data reflects short-term inflection points more quickly, while the 3-month moving average is used to reduce seasonal noise and identify underlying trends. For company-level readings, the report uses regression estimates based on relevant SEAJ equipment-category billings to project quarterly revenue for Tokyo Electron and Advantest, and compares the results with market consensus.

Methodology notes

• Industry high-frequency data trackingSEAJ billing tracking

  Use billings of Japanese semiconductor equipment suppliers to measure changes in SPE/WFE demand.

  SEAJ members cover about 25% of the global WFE market, so their monthly billings can be used to track Japanese equipment makers’ revenue trends and the direction of global equipment capex.

• Trend smoothing3-month moving average

  Use a 3-month average to reduce single-month volatility and seasonality.

  The report looks at both single-month data and the 3-month average; single-month data is more timely, while the 3-month average better reflects the underlying cyclical trend.

• Company readingRevenue regression analysis

  Use SEAJ equipment-category billings to estimate quarterly company revenue.

  The report states that the R2 of the regression between SEAJ data and Tokyo Electron revenue is 0.93, and that the regression with Advantest testing revenue is also very high, making it useful for judging upside or downside risk versus consensus for the current quarter.

• Industry forecastGlobal WFE forecast model

  Assess global WFE growth by combining DRAM, NAND, and advanced logic capex.

  The report forecasts global WFE growth of +21.4% YoY in CY2026 and +18.2% YoY in CY2027, and believes memory capex is the main source of growth.

Impact & implications

If the SEAJ billing trend continues, fundamental support across the semiconductor equipment chain will broaden from AI logic alone to memory, advanced packaging, testing, and more front-end equipment segments. From an investment standpoint, the report prefers equipment companies benefiting from HBM, a NAND recovery, advanced packaging, and domestic substitution; however, near-term earnings expectations need to be differentiated, with Tokyo Electron facing quarterly downside risk versus consensus and Advantest having the potential to outperform consensus.

Risks

• SEAJ single-month data is subject to seasonality and short-term volatility, and weaker sequential performance in a single month may affect trend judgment.
• Tokyo Electron’s near-term regression reading is below market consensus, and if confirmed by earnings, it may weigh on sentiment toward Japanese front-end equipment.
• The global WFE forecast depends on continued recovery in DRAM, NAND, and advanced logic capex; a slower memory recovery would weaken industry growth.
• Screen faces margin pressure from intense competition in cleaning equipment and declining China revenue.
• Exchange-rate changes can cause differences between USD and JPY billing growth rates, affecting cross-region comparisons.
• Equipment stocks are generally sensitive to customer capex timing, technology-node migration, and valuation discount rates.

What to watch

• Whether subsequent monthly SEAJ/SEMI billings continue to maintain strong YoY growth in the 3-month average.
• Whether Tokyo Electron’s actual June-quarter revenue confirms the regression model’s indicated downside risk versus consensus.
• Whether Advantest’s tester revenue continues to be supported by increased HBM and AI GPU testing intensity.
• The magnitude of DRAM and NAND capex recovery, as well as order progress related to HBM, CoWoS, and advanced packaging.
• The next round of earnings guidance, orders, backlog, and margin changes from Japanese, U.S., and Chinese semiconductor equipment companies.
• The pace of share gains and customer ramp progress among Chinese domestic-substitution-related equipment makers.
