Teradyne, Inc.

The forensic screens are mostly reassuring, but they do not settle the picture. The Beneish M-Score is -2.204, below -1.78 and not in the elevated manipulation-risk zone; this is a screening result, not proof either way. The Altman Z″-Score is 5.05, in the safe zone. The Piotroski F-Score is 5 of 8 computable signals, a checklist of profitability, leverage and efficiency tests; five of the eight tests that could be computed were met. Operating cash flow was 1.22 times net income for 2025, meaning cash generation exceeded reported profit, which is a supportive sign. Still, the headline growth has not yet flowed through to the balance sheet. Full-year 2025 net income of $554.05 million was only about 2% above 2024's $542.37 million, and equity was roughly flat at $2.8 billion against $2.82 billion. The risk factors name Advantest, SPEA and Cohu as test competitors, note that some rivals have greater resources, and cite internal supply at several customers. They also warn that customers may delay or cancel backlog without notice and that certain components come from sole-source suppliers. The first-quarter effective tax rate rose to 13.3% from 12.2%, partly due to Pillar Two. Cash, cash equivalents and marketable securities fell to $394.0 million from $448.3 million after the $200.0 million revolver repayment. Readers may want to look at the 10-Q cash flow discussion alongside the receivables increase, and at the Credit Agreement expiration date, to judge how the company's liquidity position develops.

Catalyst.Semiconductor Test is the engine. Per the 10-Q MD&A, first-quarter 2026 revenues were $1,282.5 million versus $685.7 million a year earlier. Semiconductor Test rose $568.3 million, or 104.8%, driven primarily by higher sales in compute related to artificial intelligence applications. Robotics grew $22.3 million, or 32.3%, on collaborative robotic arms, partly offset by lower autonomous mobile robot sales. Semiconductor Test income before income taxes reached $468.1 million versus $155.8 million. Full-year 2025 revenue was $3.19 billion, up 13.1% from $2.82 billion in 2024.

Hidden risk.The largest tension is working capital. Operating cash flow in the first quarter was $265.1 million, but changes in operating assets and liabilities used $195.5 million, driven by a $322.0 million increase in accounts receivable. Reported profit can run ahead of collected cash when receivables grow this fast. Customer geography is also concentrated: Taiwan was 41% of revenue, up from 28%, while China fell to 11% from 19%. The $750.0 million revolving credit facility is set to expire December 10, 2026, and management says it intends to extend it. Total liabilities rose to $1.39 billion at year-end 2025 from $889.42 million at year-end 2024.
