Teradyne

Teradyne is being paid for its position on the AI test toll booth exactly as designed: revenue doubled YoY, Semiconductor Test grew +128% with Memory up +248%, the company beat the high end of its own guidance, and it does it with zero debt, $517M of net cash and a 28.5% free-cash-flow margin — with management pointing at rising wafer-fab-equipment investment as the 2027 setup.

• The magnitude is hard to argue with: +103.9% YoY revenue growth on a $1.3B quarterly base, and a second consecutive record quarter that exceeded the high end of the company's own guidance rather than merely a sell-side estimate.
• Memory is the new engine: $212.333M, +248.4% YoY from $60.943M, on DRAM/HBM strength plus a NAND final-test resurgence. Memory test had been the cyclical laggard; its inflection broadens the story beyond SOC and adds a second AI-levered growth vector.
• SOC did not stall to make room: $842.971M, +112.6% YoY. Both major Semiconductor Test lines more than doubled in the same quarter, which is a market-expansion signal rather than share-shift or a mix trick.
• Operating leverage YoY is enormous: gross margin 57.2% to 59.8% and GAAP operating margin 13.9% to 32.9%, so incremental revenue dropped through at a very high rate. GAAP EPS went $0.49 to $2.38.
• Cash generation is real and unlevered: Q2 operating cash flow $469.138M and ~$378.4M of free cash flow (28.5% margin) with zero debt, having repaid the $200.0M of short-term borrowings outstanding at year-end. $517.1M of net cash plus a $515.0M Technoprobe stake sit outside the operating business.
• The MLTP joint venture is aimed at the right adjacency: a 75%-controlled vehicle with MultiLane for $157.8M, explicitly to build test solutions for AI-datacenter high-speed data connections. Interconnect test is where content growth is migrating as rack-scale AI systems proliferate.
• Duopoly structure and installed-base economics mean the demand does not need to be won twice: ATE is a two-player global market, and testers pull recurring service and consumable-adjacent revenue ($109.5M of Q2 revenue was recognised over time).
• Management's forward framing is about capacity, not inventory: 'rapid increase in wafer fab equipment investment sets the stage for continued growth in 2027 and beyond' — a WFE-cycle statement, which historically leads ATE demand rather than coinciding with it.

The sequential picture contradicts the YoY headline: Q3 guidance implies revenue down ~6% and non-GAAP EPS down ~19% from Q2, gross margin already fell 60.9% to 59.8% and non-GAAP operating margin 37.5% to 33.7% as opex jumped $48.9M in one quarter, and 87.2% of revenue now comes from Asia Pacific — all capitalised at roughly 37x annualised non-GAAP earnings on what is structurally a cyclical equipment business.

• Q3 guidance steps down on both lines: revenue midpoint $1,250M versus $1,328.990M delivered (-6.0% QoQ) and non-GAAP EPS midpoint $2.00 versus $2.47 (-19.0% QoQ). Teradyne gives no annual guidance, so there is no company-sourced visibility past September.
• Margins peaked in Q1, not Q2: gross margin 60.9% to 59.8% and non-GAAP operating margin 37.5% to 33.7% — a ~380bps sequential contraction on 3.6% MORE revenue. Memory test carries lower gross margin than SOC, so the fastest-growing line is the margin-dilutive one.
• Operating expenses grew far faster than revenue sequentially: $307.947M to $356.808M (+15.9%) against +3.6% revenue. S&A rose $25.8M and E&D $20.7M, part of it MLTP consolidation from 2026-04-08. If revenue steps down as guided while this cost base persists, decremental margins will be steep.
• Geographic concentration worsened sharply: Asia Pacific is 87.2% of Q2 revenue (from 77.7%), with SOC alone at $814.023M of $842.971M sold into Asia Pacific. The company's own risk factors name US export controls and China tariffs — a single regulatory action hits nearly nine-tenths of revenue.
• The MLTP deal is 83% goodwill: $131.6M of the $157.8M purchase price, non-deductible, plus $46.7M of intangibles amortising over only 4.7 years. Against a track record of $762.566M of cumulative accumulated goodwill impairment — Teradyne has already written off more acquisition goodwill than the $663.817M it currently carries.
• Robotics remains the unfixed problem: $99.917M (7.5% of revenue) growing 33.5% — respectable but far slower than the test business, and it sits inside a goodwill base that has absorbed large historical impairments. It dilutes the 'pure AI test toll booth' framing.
• The Technoprobe equity stake is a slow drag: carrying value fell to $514.957M from $537.098M, and equity in net earnings of affiliate was a $1.946M deduction in Q2 FY26. A ~$515M asset producing negative income is dead capital until it turns.
• Working capital is inflating with the boom: accounts receivable $1,109.711M versus $786.913M at 2025-12-31 (+41%) and prepayments $468.174M. That is the classic late-cycle equipment pattern — shipments ahead of collections.
• Valuation prices continuation, not cyclicality: $365.80 against annualised Q2 non-GAAP EPS of $9.88 is ~37x, and ~12.7x TTM revenue on an enterprise value of ~$56.7B. Even after fading from a $437.92 52-week-high close, the multiple assumes the ATE cycle does not roll.
