TSMC's AI-Driven Quarter Reinforces Valuation and Execution Concerns

What happened

TSMC reported a strong first quarter with revenue of $35.90B, up 40.6% year-over-year, bolstered by increased AI chip production and gross margin expansion to 66.2%. The company guided for second-quarter revenue of $39.0B–$40.2B and gross margins between 65.5%–67.5%, signaling continued high utilization. However, the DeepValue master report, based on recent 20-F and 6-K filings, maintains a 'WAIT' rating with an attractive entry at $320, as the stock at $375 already prices in robust AI demand. Key risks include execution friction in advanced packaging capacity, overseas expansion diluting margins by 2%–4%, and geopolitical tensions that could disrupt operations. Investors must now watch for gross margin sustainability and capex execution against the $52B–$56B FY26 plan to assess forward returns.

Implication

The strong quarter confirms TSMC's role as an AI bottleneck, but at a P/E of 31.5, the stock offers thin margin of safety, requiring careful monitoring of gross margins to avoid slipping below 63%. Execution on the $52B–$56B capex plan is critical to relieve packaging constraints and convert AI backlog, with any shortfall capping upside potential. Overseas expansion introduces structural margin dilution of 2%–4%, and geopolitical risks could shift from volatility to operational disruption, impacting volumes. Impairment losses disclosed in filings highlight capital misallocation risks, necessitating vigilance on new charges. Over the next 6-12 months, investors should track 2Q26 results against guidance and capex trends, with a base case value of $410 dependent on margin maintenance and demand conversion.

Thesis delta

The news reinforces strong operational momentum but does not change the DeepValue thesis that TSM is fully valued at current levels. The thesis shift hinges on whether gross margins can average ≥65% while capex stays on plan, or if they fall below 63% with new impairments, driving a re-rating toward the $300–$470 range.
