- **Market Cap:** ~$2.25T

## Moat

Unmatched process-technology leadership at 3nm and below, with customer redesign costs making TSMC effectively irreplaceable for any leading-edge chip. The AI boom has deepened the design ecosystem moat as every major AI chip — from NVIDIA Blackwell to Google TPU to custom hyperscaler ASICs — runs exclusively on TSMC silicon. NVIDIA's reaffirmed TSMC exclusivity for its next-gen 'Rubin' architecture (citing the CoWoS advantage) and Intel 18A's persistent yield gap (50–55% vs. TSMC N2's 70%+) reinforce the thesis that no credible foundry alternative exists at the leading edge as of mid-2026.

### The Fabrication Monopoly

TSMC's moat rests on three reinforcing pillars: **Process Secrecy, Customer Lock-In, and Scale Economics**:

- **Process Technology Secrecy:** TSMC's 3nm (N3E) and 2nm (N2, now in high-volume manufacturing) process nodes represent decades of proprietary yield-learning that no competitor has replicated. Intel Foundry and Samsung are 1–2 generations behind on leading-edge logic, and that gap is widening, not closing. A16 (backside power delivery) and N2P are scheduled for H2 2026, extending the lead further.
- **Customer Redesign Lock-In:** Apple, NVIDIA, AMD, and Qualcomm design their chips specifically for TSMC's PDK (process design kit). Re-taping a chip for a different foundry costs $500M–$1B+ and 2–3 years of engineering time — making switching economically irrational for any customer at leading-edge nodes. AI ASIC customers (Google, Amazon, Microsoft, Meta) are now in the same locked-in position.
- **Yield-Learning Compounding:** At leading-edge nodes, yield (the % of functional chips per wafer) is the decisive competitive variable. TSMC's decades of high-volume production have built an enormous yield-learning advantage that compounds with each new node — a gap competitors cannot close by simply spending more capital. Q4 2025 gross margins hit a record 62.3%, reflecting this pricing power.

**Moat verdict:** TSMC is a direct and primary beneficiary of the AI era — every frontier AI model requires more TSMC-made chips, and the AI boom has structurally deepened the design ecosystem network effects. The AI-resilient moats (proprietary process data, regulatory lock-in from CHIPS Act and allied government partnerships, customer PDK embedding) are all intact or strengthening. The primary risk is geopolitical, not competitive: Taiwan cross-strait tensions and US tariff policy are the only plausible paths to moat disruption, and TSMC's $165B US investment commitment is actively reducing that structural risk.

## Growth

Q1 2026 delivered record revenue of $35.9B (+40.6% YoY) with net income +58.3% YoY; Q2 2026 guidance points to $39.0–40.2B revenue (+10% QoQ) and gross margin of 65.5–67.5%. Management raised FY2026 outlook to 30%+ revenue growth and reaffirmed 25% USD CAGR through 2029, with AI accelerator revenue still tracking 54–56% CAGR. N2 in HVM with strong yield and reportedly sold out through 2026 (Apple ~50% of initial capacity); CoWoS is 'extremely tight and sold out through 2026' per CEO C.C. Wei, with NVIDIA holding ~60% of 2026 allocation. May 2026 monthly revenue (reported June 10) hit a record NT$416.98B (+30.1% YoY, +1.5% MoM), with Jan–May revenue +30.0% YoY; June monthly revenue and Q2 2026 earnings are due July 10 and July 16 respectively, both still pending as of this update. A finalized US-Taiwan tariff framework (April 2026) scaled TSMC's committed US investment to ~$465B across 11 fabs in exchange for a reduced 15% tariff on Taiwan semiconductor imports, defusing the prior forced-diversification overhang.

- **Revenue CAGR estimate:** 25–30%
- **Primary type:** TAM expansion
- **Margin trend:** expanding
- **Key risk (moderate):** The prior forced-diversification risk has been substantially de-risked: the April 2026 US-Taiwan tariff framework reduced import tariffs to 15% in exchange for scaling TSMC's US investment to ~$465B/11 fabs, and NVIDIA has reaffirmed TSMC exclusivity for its next-gen 'Rubin' architecture citing the CoWoS advantage, with Intel 18A yields still stuck at 50–55% versus TSMC N2's 70%+. Residual risk: if Intel 18A yields reach parity (>65%) by end of 2027 and a major AI ASIC customer (Google TPU, Amazon Trainium) shifts >15% of leading-edge wafer volume away from TSMC, the AI ASIC anchor thesis weakens — but this is now a 2027+ risk rather than a near-term one.
- **Drivers:**
  - AI Accelerators / CoWoS — ~17–19% of wafer revenue FY2025; CoWoS sold out through 2026, NVIDIA ~60% of allocation (~800–850k wafers); global demand +93% to 2.69M wafers guided for 2027 (accelerating)
  - N3/N2 Advanced Logic — N2 in HVM since Q4 2025 with strong yield, largely sold out through 2026 (Apple ~50%); NVIDIA reaffirmed TSMC exclusivity for Rubin; N2P/A16 volume production H2 2026 (accelerating)
  - Overseas Fabs (AZ/Japan) — US commitment scaled to ~$465B across 11 fabs (from $165B) under April 2026 tariff framework; 2nd Arizona fab equipment move-in Q3 2026; Japan Fab 1 operational (stable)
- **Score derivation:** Base 82 (FY2026 raised to 30%+) + 5 TAM expansion (AI accelerator at 54–56% CAGR, sovereign AI buildout) + 3 customer visibility (N2/CoWoS sold out through 2026, NVIDIA reaffirmed Rubin exclusivity) − 2 overseas fab dilution (reduced from −3: April 2026 tariff framework de-risked forced-diversification scenario, though $465B Arizona buildout still carries margin-mix drag) = 88

## Valuation

At $434.55 (July 2, 2026) — up ~6% from $408.75 in early June and now 21% of the way from the base case ($400) toward the bull case ($560) — TSMC has drifted from fairly valued toward a modest premium, yielding a valuation score of 61 (down from 64). Fundamentals remain on track (N2/CoWoS sold out through 2026, FY2026 guide of 30%+ revenue growth intact) and the April 2026 tariff framework removed a key overhang, but the price run-up ahead of the July 16 Q2 earnings report has consumed some of the prior margin of safety; further re-rating now depends on Q2 results confirming the guided trajectory or the bull-case catalysts (sovereign AI demand, A16 wins) materialising.

**Fair value:** ~$400 — Base-case fair value of ~$400 reflects ~30x forward 2026E EPS — reasonable for a monopoly franchise guiding 25% revenue CAGR through 2029. The geopolitical discount has narrowed further: the April 2026 US-Taiwan tariff framework (15% tariff in exchange for scaling US investment to ~$465B/11 fabs) reduces the tail risk that previously justified a larger discount, though Taiwan cross-strait tensions remain a residual factor.

| Multiple | Value | Note |
| --- | --- | --- |
| Trailing P/E (GAAP) | ~37× | ~$11.7 TTM EPS (ADS) incl. Q1 2026 (+58% net income) |
| Forward P/E (NTM) | ~30× | consensus NTM EPS est. ~$14.5, guidance unchanged pre-Q2 |
| PEG Ratio | ~1.2× | fwd P/E ÷ 25% EPS CAGR |
| Price / Sales (NTM) | ~15× | ~$2.25T mkt cap / ~$152B NTM rev |
| Price / FCF | ~61× | $32B FCF (FY2025) |

At ~30× forward P/E, TSMC now trades at a wider premium to the semiconductor sector median (~20×) than in early June, as the price has run ahead of the last reported quarter while Q2 results (due July 16) and June monthly revenue (due July 10) remain pending. A PEG of ~1.2× is still within the fairly-priced-for-growth band but has ticked up from ~1.1×, leaving less margin of safety if the July 16 report or guidance disappoints. The gap between trailing (~37×) and forward (~30×) P/E continues to signal an earnings ramp as N2 scales and AI accelerator mix increases, but confirming that ramp now depends on the imminent Q2 print rather than being already validated by it. _(as of July 2026 (price ~$434.55))_
