Advantest Q2 FY26: SoC Testers Sold ¥353.3B. The Guide Is Built at ¥150 to the Dollar.

Advantest's SoC testers sold ¥353.3B in the September quarter, more than the whole company sold in any quarter before April, and it raised its full-year forecast to ¥1,863.0B. That forecast assumes ¥150 to the dollar against ¥161 in the quarter and a second-half operating margin of 50.1% as testers start paying the new DRAM price. Our call: October–December sales reach at least ¥500.0B at an operating margin of at least 50.0%; below ¥477.7B refutes it.

The setup

The forecast Advantest raised on October 28 is a floor dressed as a forecast. The quarter under it makes the tester a toll on AI compute volume, not a cyclical equipment line: SoC test systems alone sold ¥353.3B (~US$2.19B), up 103.4% on the year, and the company raised its full-year forecast to ¥1,863.0B (~US$11.57B) of sales. Then it built the second half at ¥150 to the dollar against the ¥161 it had just reported, and at an operating margin of 50.1% against the 55.9% it had just earned. Our call is that the guide is a floor: October–December sales, reported in late January 2027, reach at least ¥500.0B at an operating margin of at least 50.0%; sales below ¥477.7B, no growth on the quarter, refute it.

Advantest (6857, Tokyo Stock Exchange Prime) reported on October 28, 2026. Its fiscal 2026 runs from April 2026 to March 2027, so the second quarter is July to September. Sales were ¥477.7B (~US$2.97B at ~¥161/US$, the quarter's average rate, approximate), up 81.7% on the year and 30.0% on the quarter. Gross margin was 71.1%. Operating income was ¥266.8B (~US$1.66B), a 55.9% margin, up 146.0% on the year and 40.4% on the quarter. Net income was ¥193.3B (~US$1.20B), up 142.7% and 10.6%, and basic EPS for the quarter was ¥267.75. All four are quarterly records. For the half, sales were ¥845.2B (~US$5.25B, +60.5%) and operating income ¥456.8B (+96.5%).

Read management's framing against the arithmetic. The full-year forecast went up for the second time in three months. Sales rise to ¥1,863.0B from ¥1,714.0B in July, operating income to ¥967.0B from ¥846.0B, net income to ¥741.5B from ¥660.0B, and EPS to ¥1,027.08. That is 65.1% more sales than fiscal 2025's ¥1,128.6B. The quarter's own detail says where the growth went. SoC testers, the V93000 platform that tests GPUs, custom ASICs and CPUs, were 74.0% of sales, the highest share in the nine quarters the deck covers. Memory testers rose 21.6% on the year. And three lines grew on the balance sheet that the income statement does not explain: inventory up ¥120.7B in the half, customer advances that brought in ¥44.2B, and ¥364.7B more investment securities, most of it a fund the company calls strategic and does not name. Connecting the dots works through those.

Of ¥477.7B of sales, SoC test systems were ¥353.3B. Cost of sales took ¥137.9B, leaving a 71.1% gross margin; after ¥73.0B of SG&A and other items, operating income was ¥266.8B, a 55.9% margin. Financial income, mostly valuation gains on strategic investments, added ¥12.3B before tax. Quarterly figures = six months to September 30, 2026 less three months to June 30, 2026. Segments from the briefing deck's product split (Test Systems ¥436.7B = SoC + memory + other systems; Services & Others ¥41.1B = support services + others). SG&A, net = gross profit less operating income. Financial income ¥12,336M, financial expenses ¥3,003M, income tax ¥82,849M, all derived.

One piece of context before the argument. The yen did part of the work: the quarter's average rate was ¥161 to the dollar against ¥146 a year earlier, and 99.4% of first-half sales went to customers outside Japan. The company does not give a sales sensitivity; it gives an operating one, ¥5.8B of full-year operating income per yen of weakness against the dollar.

The company's account of the quarter is volume plus complexity. "The AI-related semiconductor market is experiencing a period of high growth that could be described as a 'megacycle,' surpassing what is generally considered a 'supercycle'," the briefing script says, with tester demand driven by "increasing semiconductor unit volumes, along with increasing test content and test insertions with each new generation." Decode: Advantest is telling investors to stop reading it as a capex cycle. A wafer-fab tool is bought once per unit of capacity; a tester is bought per unit of capacity times the minutes each chip spends on it, and the second term grows with every generation of package. If that is right, test spending can grow faster than the chips it tests, which is what this quarter shows.
