Summary

  • Teradyne reported $1.306bn of third-quarter 2026 revenue, up 70% from a year earlier. Semiconductor Test supplied $1.072bn. The company says AI demand drove record Memory and Integrated Systems Test revenue.
  • The quarter's cash-flow table records $170.9m used in inventories and $165.3m in prepayments and other assets, partly offset by $225.8m supplied by accounts payable and other liabilities. Operating cash reached $313.6m. The funding cycle behind the sales boom deserves as much attention as the sales figure.

The fast line and the expensive line

Teradyne's latest quarter looks simple from the top of the income statement. Revenue reached $1.306bn, against $769m a year earlier. The company put Semiconductor Test at $1.072bn, far larger than Product Test at $138m or Robotics at $96m. Its 27 October results release says memory and integrated-systems testing set revenue records on AI-related demand. Test systems are one of the less glamorous toll booths on the route from a chip design to a shipping data-centre machine. They have to be built and delivered before the manufacturer can collect the full economic reward.

The same release shows what the rush did to cash moving through the business. Inventories absorbed $170.9m in the quarter, compared with $10.9m a year earlier. Prepayments and other assets absorbed another $165.3m, against $53.5m. Add those two cash-flow entries and $336.3m went into assets before their eventual conversion back to cash. These entries cover the whole company; the release gives no product-level allocation to AI test equipment. The timing still matters. Revenue can accelerate while the physical and contractual machinery behind it asks for cash first.

Teradyne was not left to fund that load alone. Accounts payable and other liabilities supplied $225.8m of cash, more than double the $104.3m supplied in the year-earlier quarter. Supplier credit and accrued obligations therefore offset much of the asset build in the cash-flow bridge. Across just those three lines, the net use was $110.4m. Deferred revenue and customer advances supplied another $13.2m. None of these numbers describes a customer order book; together they show who carried the quarter's production and payment timing.

Cash is arriving, even while capital is tied up

Operating activities produced $313.6m of cash, compared with $49.1m a year earlier. Property and equipment purchases used $86.3m, up from $46.7m. Subtracting those reported purchases from operating cash leaves $227.3m for the quarter, against $2.4m on the same simple calculation a year earlier. The growth is real enough to survive the working-capital demand. That is the important counterweight to the inventory story: rising inventory ties up capital, but this quarter also generated far more cash.

The balance sheet confirms the scale of the physical and payment commitments, using a different comparison period. At 27 September, inventories stood at $575.0m, up from $379.6m at the end of December 2025. Prepayments were $613.7m, up from $427.6m. Receivables reached $1.111bn, against $786.9m at year-end. Accounts payable also rose, to $517.0m from $269.2m. Those are September-to-December balance changes, not the quarter's cash-flow movements. Mixing the two comparisons would make a tidy but false story.

Teradyne's fourth-quarter sales guide of $1.250bn to $1.350bn straddles the third quarter's $1.306bn. The company has published a broad range, not a promise of another 70% jump. A buyer of test capacity, a supplier extending terms and an investor looking at cash conversion have different claims on the same cycle. Management controls production commitments and inventory planning; customers control acceptance and payment timing. That is where the margin between a healthy build and an expensive delay lives.

The order is not finished when the machine is made

The market often rewards the first number in this sequence: revenue. Teradyne's sequence has more steps. Components become stocked systems; stocked systems become delivered and accepted equipment; receivables become cash. Payables give the company time to travel that route, but they also come due. The financial release does not break out product-level inventory, the contents of prepayments, customer payment terms or accepted AI test orders. Those missing details keep a reader from assigning the $336.3m asset use to one customer programme.

The next cash-flow statement can settle a more useful question. If inventory and prepayments cycle back while operating cash remains strong, the third-quarter outlay will look like capacity put to work. If the asset lines keep drawing cash faster than sales turn into collections, the same revenue boom will carry a heavier financing bill. Teradyne has already shown both sides of the ledger. The next quarter will show how long its money has to wait on the test floor.
