What’s Driving TSMC’s Growth? Arizona, Pricing Power, and the AI Boom

Pricing Power: 5–10% Hikes From 2026 Through 2027

TSMC's ability to raise prices reflects its dominant position in advanced chip manufacturing. Multiple reports confirm the company has notified customers of planned increases:

• 5–10% on advanced nodes (5nm, 4nm, 3nm-class processes) starting in 2026, covering approximately 74% of TSMC's wafer revenue . Some reports indicate the hikes extend to 7nm and legacy nodes .
• Differentiated pricing by application: smartphone processors see 5% increases, CPUs 7%, and AI/HPC processors 10% .
• Further increases in the second half of 2026 and into 2027: TrendForce reports TSMC is eyeing up to a 15% hike on 3nm in 2H26, followed by an additional 5–10% in 2027 .

At the June 2026 shareholder meeting, CEO C.C. Wei warned the AI chip shortage "will persist for years" and signaled that TSMC's "stable pricing" pledge does not mean flat prices — the company is executing measured annual increases rather than sudden spikes . With Nvidia, Apple, and others competing for every 3nm and 2nm wafer slot, TSMC holds the negotiating advantage .

AI Demand Drives >NT$100 EPS and >60% Gross Margins

Analyst projections for TSMC's financial performance are aggressive but grounded in current data:

• EPS of NT$98.02 is the consensus forecast for fiscal 2026, up from NT$65.47 the prior year — a 49.7% increase . The NT$100+ milestone is expected next year, with a consensus of NT$122.38 . Goldman Sachs has raised 2026 and 2027 EPS estimates by 9–15%, predicting EPS will reach NT$100 by 2027 . Citi's estimates for 2027 and 2028 are even higher, at NT$130.72 and NT$165.99 respectively .
• Gross margins exceeding 60% through 2028 are a widely cited bull-case thesis. Goldman Sachs forecasts >60% gross margins through 2028, citing "mild overseas fab dilution" and "continued productivity improvements" . TSMC reported 59.9% full-year gross margin for 2025 and 62.3% in Q4 2025 alone . Management guided Q1 2026 gross margin to 63–65% .

The Caveat: Overseas Fab Dilution Risk

The most significant risk to the margin thesis comes from TSMC's own overseas expansion. A Morningstar equity analyst report from June 2026 notes that management projects gross margin dilution from overseas fabs to widen by 300–400 basis points around 2028–2029, citing inflation and tariffs . This could pull margins lower than the bull case suggests, even as AI demand remains robust.

Putting It Together

TSMC's growth story is well-supported by current data. The Arizona expansion locks in future capacity, pricing power ensures revenue per wafer continues rising, and AI demand provides a multi-year demand floor. The 300–400bp margin dilution risk from overseas fab ramp-up is a meaningful caveat, but most analysts — including Goldman Sachs—still expect gross margins to remain above 60% through 2028 . For investors and industry watchers, the key tension to monitor will be between TSMC's pricing leverage and the rising costs of its global manufacturing footprint.
