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

Taiwan Semiconductor Manufacturing (TSMC) reported robust Q3 results, with revenue climbing 41% to $33.1 billion and EPS soaring 51%, primarily driven by strong demand for AI chips and a 19% sequential increase in smartphone revenue. The company raised its full-year revenue growth forecast to the mid-30s percentage range, citing sustained AI demand and a mild recovery in other chip markets. Despite anticipated margin pressure from overseas expansion, TSMC maintains its leadership in advanced semiconductor manufacturing, with its stock considered reasonably valued at 26x forward P/E given its substantial growth trajectory, particularly in the AI sector.

Analysis

Taiwan Semiconductor Manufacturing (TSMC) reported robust Q3 results, with revenue climbing 41% year-over-year to $33.1 billion and EPS soaring 51% to $2.92 per ADR. This strong performance was primarily driven by significant demand for AI chips and a 19% quarter-over-quarter increase in smartphone revenue, which now constitutes 30% of total revenue. Advanced nodes (7nm and under) represented 74% of revenue, up from 69% a year prior, underscoring TSMC's technological leadership.

The company raised its full-year revenue growth forecast to the mid-30% range, up from 30% previously, attributing this to sustained AI demand and a mild recovery in other chip markets. Q4 revenue is projected between $32.2 billion and $33.4 billion, implying approximately 22% year-over-year growth at the midpoint. While gross margins expanded by 170 basis points to 59.5% in Q3, TSMC anticipates a 2-3% annual negative impact on gross margins from overseas expansion, potentially widening to 3-4% later.

TSMC remains the undisputed leader in advanced semiconductor manufacturing, with AI chip demand projected to grow at a mid-40% CAGR through 2029, currently outpacing this projection. The company's commitment to building cutting-edge capacity in the U.S. (2nm, 1.6nm) reinforces its strategic position, despite higher operating costs potentially leading to price increases. At a forward P/E of 26x based on 2026 estimates, the stock appears reasonably valued given its substantial growth trajectory and critical role in the AI infrastructure buildout.

Key Decisions for Investors

• Investors should consider TSMC's strong fundamental performance and its critical, undisputed leadership in advanced semiconductor manufacturing, particularly given the accelerating demand for AI chips.
• The raised full-year revenue guidance and reasonable forward P/E valuation suggest continued growth potential, but monitor the anticipated negative impact on gross margins from overseas expansion.
• While U.S. expansion costs may lead to price adjustments, TSMC's technological edge in shrinking node sizes (e.g., 2nm, 1.6nm plans) solidifies its long-term competitive advantage against rivals.
