Advantest reported quarterly results that outpaced analyst expectations but saw its share price decline on the day. The semiconductor testing equipment maker recorded revenue of ¥328.1 billion for the fourth quarter, a 20% increase from the prior quarter and roughly 14% above consensus estimates. Net income for the period reached ¥126.8 billion, beating consensus by 38%.
Profitability metrics were strong: gross profit margin stood at 67.4%, while operating profit margin came in at 46.7%. These margins reflect the company's ability to convert its top-line strength into substantial operating profitability during the quarter.
On the product mix front, systems-on-chip (SoC) tester sales were a notable driver, rising 44% quarter-over-quarter. By contrast, revenue from memory testers declined 36% from the prior quarter. Geographic performance was uneven. Taiwan delivered a pronounced contribution, with revenue up 83% quarter-over-quarter. South Korea and China experienced declines, with South Korea down 39% and China down 13% in the quarter.
Even with the quarterly outperformance, investors reacted negatively to management's fiscal year 2027 guidance, which the company framed as conservative relative to its typical forecasting approach. Revenue guidance for the fiscal year was set close to consensus levels, and that cautious posture appeared to outweigh the stronger-than-expected fourth-quarter results in the market's assessment.
Advantest pointed to a set of external factors that could limit near-term growth. Specifically, the company highlighted wafer starts, CoWoS capacity, and the level of memory supply at its customers' facilities as potential constraints. Management presented these items as risks that could affect the pace at which demand converts into shipments and revenue.
The market reaction was immediate: shares declined 5.5% on the day the results were released, underscoring investor sensitivity to forward guidance even when current-quarter metrics are robust.
Summary
- Advantest posted Q4 revenue of ¥328.1 billion and net income of ¥126.8 billion, both exceeding consensus.
- SoC tester revenue rose 44% QoQ while memory tester revenue fell 36% QoQ.
- Geographically, Taiwan surged 83% QoQ; South Korea and China decreased 39% and 13% QoQ respectively.
- The company set fiscal 2027 revenue guidance near consensus and described its outlook as conservative, citing supply-side constraints.
Key points
- Strong quarterly performance with high gross and operating margins, reflecting solid profitability in the testing equipment business.
- Product mix divergence: significant growth in SoC tester demand contrasted with a steep decline in memory tester revenue.
- Regional concentration of strength in Taiwan, while South Korea and China lagged.
Risks and uncertainties
- Supply-side limits - wafer starts could restrain production capacity and therefore revenue realization.
- Packaging capacity - constrained CoWoS capacity may impede the company's ability to meet demand for certain advanced packages.
- Customer inventory - the level of memory supply at customers' facilities could dampen orders for memory testers and affect revenue.
