Jabil guided fiscal 2027 revenue to $44.5 billion against fiscal 2026 revenue of $35.954 billion. That is an $8.546 billion single-year step-up, and management named AI infrastructure as the primary driver. Contract manufacturers do not guide to 23.8% growth on hope; they guide on booked capacity and customer forecasts already loaded into their planning systems. The marginal AI dollar this quarter is being absorbed at the assembly, test, and interconnect layers.
Meanwhile Intuit closed at $281.08 after growing fiscal 2026 revenue 14% to $21.448 billion, and the aggregate sell-side rating is Hold. Autodesk closed at $212.00 after 16.1% revenue growth. Growth rates at the application layer are competitive with the hardware layer. The capital is not treating them the same way.
The Spec
Teradyne gained 7.75%, the largest single-session move in the group, on sentiment around its Magnum E2 memory test platform and Iris 100 optical test platform. High-bandwidth memory is stacked DRAM joined by through-silicon vias, and every die must pass test before stacking and again after. That double insertion makes test time a fixed cost per finished stack, independent of how cheap the wafer gets.
The financial consequence is direct. Test capacity sets the ceiling on how many HBM stacks reach a finished accelerator, which means test equipment orders lead memory revenue by one to two quarters. A tester sold today is also a multi-year service and consumables annuity. That is a structurally higher-quality revenue stream than the die it qualifies.
The Bottleneck
Logic wafer starts are not the constraint this cycle. The constraint is memory test throughput and optical interconnect supply — the two layers that convert raw silicon into a functioning rack.
Corning rose 2.33% to $164.16 after Truist raised its target from $175 to $182, coinciding with a multiyear AT&T fiber contract valued above $3 billion. The AT&T award is carrier access fiber, not data center optics. But both draw from the same glass preform and fiber draw capacity, and a multiyear carrier commitment removes that capacity from the available pool for years.
Jabil's implied fiscal 2027 growth of 23.8% runs 9.8 percentage points ahead of Intuit's fiscal 2026 revenue growth of 14%.
Fiber draw lines are capital-intensive and slow to add. When a supplier signs a multiyear volume contract, the pricing power shifts to the supplier for the duration. Corning is being paid for scarcity it already controls.
The Unit Economics
Three margin structures are competing for the same AI capital. Contract manufacturing is a thin-margin, high-asset-turn business, so Jabil's $8.5 billion of incremental revenue converts to a modest absolute profit increase. Test equipment carries high gross margin on the tool plus recurring service revenue, giving Teradyne the best incremental economics per dollar of AI capex. Materials and optical components sit between the two, with pricing protected by capacity scarcity rather than by software-like margins.
Application software is the outlier. SAP fell 1.51% to €183.92 on Xetra despite 22% cloud revenue growth and a 27% increase in cloud backlog. Growth and backlog expansion at that rate did not hold the price. The same pattern shows in Intuit's rating spread: Royal Bank of Canada reaffirmed Outperform with a $385 target while the consensus average target sits at $431. The firm carrying the bullish rating has the lower number.
Software companies that consume AI capacity pay rising inference costs as an operating expense. Companies that supply the capacity book it as revenue. Until cost-per-inference falls materially, that asymmetry persists.
The Inflection
A note on calibration first. My recent calls on deal-structure durability and on power-equipment levels were wrong, and the levels I set were too wide to be falsifiable in a useful window. These are tighter and tied to named catalysts.
Corning is where this argument is most directly tested. A close above $170 within 15 sessions — roughly 3.6% above the current level and below Truist's $182 target — would confirm that optical and fiber capacity is being repriced as an AI input rather than a telecom commodity. A close below $158 in the same window invalidates it and says the AT&T award was a one-contract event with no read-through to data center optics.
Skyworks Solutions at $85.03 offers a dated near-term test. The Qorvo combination is expected to close October 5, and a close above $88 within 10 sessions would indicate the market is paying for consolidated RF scale despite the recent revenue decline.
What would change this view: evidence that HBM test insertion times are falling fast enough to decouple test capacity from memory output, or a Teradyne order book that flattens next quarter. Either would move the bottleneck back upstream to wafer capacity, and the entire allocation argument would need rebuilding.
At $164.16, Corning is valued as a materials supplier while being paid as an interconnect bottleneck owner. That gap is the clearest mispricing in this group.
