TSMC's Capacity Crunch: Wedbush Backs the AI Story Even as Margin Pressures Build

Wedbush has reaffirmed its "Outperform" rating on TSMC, framing the chipmaker as a quality holding for long-term, AI-driven growth. The call landed the same week Bloomberg reported concerns that rising financing costs could slow spending on AI infrastructure — a reminder that analyst conviction and near-term market nerves are pulling in opposite directions.

The stock shed 2.5% on Friday, even as the bank kept its constructive view intact. That divergence captures the current mood: investors are weighing whether higher borrowing costs will delay large infrastructure projects and dent the earnings of Asian suppliers, while chip orders themselves have so far shown few signs of softening. AI demand, by Bloomberg's account, has stayed robust.

A Record Quarter Behind the Rating

The operational backdrop gives Wedbush plenty to work with. TSMC's third-quarter 2026 results, presented on Thursday, showed a net profit of NT$763.1 billion — up 68.7% year on year and the sixth consecutive quarterly record. Revenue for the period also came in ahead of market expectations, which Wedbush read as a positive signal for the closing quarter.

Guidance for that final quarter points to revenue of US$52.3–54.3 billion. Management sees no cooling in AI demand and says orders for advanced process technologies continue to outstrip available capacity. CEO C.C. Wei has been equally direct about the bottleneck: demand for AI computing remains above what the company can supply, and even its CoWoS advanced packaging lines are running above rated capacity.

High-performance computing now accounts for 68% of total revenue, having grown 22% quarter on quarter. That concentration explains both the momentum and the pressure — extra demand cannot be converted into extra shipments overnight.

Expansion Has a Price Tag

TSMC plans capital expenditure of US$60–64 billion for 2026, funding new fabs in Taiwan, Japan and the United States. The spending is not only about volume. The company is simultaneously pushing into more advanced nodes, and those transitions weigh on margins during ramp-up.

The 2-nanometer process already accounts for 8% of wafer revenue, and its production ramp cut gross margin by 1.3 percentage points versus the prior quarter. Overseas plants are expected to dilute margins initially and more heavily later on. For investors, the question is shifting from order intake to execution — how efficiently TSMC can run its new sites and processes.

The timeline stretches across several quarters. Shipments from the planned 3-nanometer facility in Arizona are slated to begin in the third quarter of 2027, with further production starts in Tainan scheduled for the first half of 2027 and early 2028. Delays in these ramps would limit how quickly the company can work down its demand backlog.

What Actually Matters From Here

TSMC expects roughly 44% revenue growth in US-dollar terms for 2026 — a forecast, not a realized figure, but one that underscores the underlying dynamism. The pivotal issue for shareholders is not simply whether the AI boom endures. It is whether TSMC can reliably turn that demand into additional shipments and profit.

Wedbush's thesis rests on exactly that distinction: the long-term demand picture, not the latest earnings print. So long as healthy chip orders stand against the financing worries, the operational case holds. Project delays on the customer side would be the warning signal worth watching — falling share prices alone are not.
