After Upbeat Outlook, Is It Time to Buy Taiwan Semiconductor Manufacturing?

Taiwan Semiconductor Manufacturing (TSM) reported strong Q3 results, with revenue up 41% to $33.1 billion and EPS soaring 51% to $2.92, driven by robust demand for advanced nodes (7nm and below comprising 74% of revenue) and growth in smartphone and HPC segments. The company raised its full-year revenue growth outlook to mid-30% and projected Q4 revenue between $32.2 billion and $33.4 billion, citing sustained strong AI chip demand and a mild recovery in other markets. Despite anticipating a 2-3% annual drag on gross margins from overseas expansion, TSMC remains the undisputed leader in advanced semiconductor manufacturing, with plans for 2nm and 1.6nm technology, and its valuation of 26x forward P/E (2026 estimates) is considered attractive given its growth prospects.

Analysis

Taiwan Semiconductor Manufacturing (TSM) delivered robust Q3 results, with revenue up 41% to $33.1 billion and EPS soaring 51% to $2.92 year-over-year, both exceeding expectations. This strong performance was driven by advanced node technologies (7nm and under comprising 74% of revenue) and significant margin expansion, with gross margin at 59.5% and operating margin at 50.6%.

The company raised its full-year revenue growth outlook to the mid-30% range, projecting Q4 revenue between $32.2 billion and $33.4 billion. This optimistic guidance is fueled by strong, accelerating demand for AI chips, expected to grow at a mid-40% CAGR through 2029, alongside a mild recovery in broader chip markets.

Despite undisputed leadership in advanced manufacturing and plans for 2nm and 1.6nm nodes, TSMC anticipates a 2-3% annual drag on gross margins from overseas expansion, potentially widening to 3-4% later. This cost increase could prompt some customers to seek alternatives, though competitors like Samsung face persistent yield challenges.

TSMC's pivotal role in AI infrastructure and technological dominance, combined with its strong financial performance and upgraded guidance, supports a highly positive outlook. Its forward P/E of 26x based on 2026 estimates appears attractive despite potential margin pressures from global expansion.

Key Decisions for Investors

• Monitor TSMC's gross margin trajectory closely, especially the impact of overseas expansion costs, as this could affect profitability.
• Evaluate the competitive landscape for advanced nodes, considering potential customer shifts due to pricing, while acknowledging TSMC's current technological lead and competitors' yield issues.
• Consider TSMC's long-term growth potential driven by AI chip demand and its strategic position in advanced manufacturing, which appears undervalued at a 26x forward P/E based on 2026 estimates.
