TSMC Stock Falls 1.8% Despite Record Profit as AI Spending Concerns Hit Chip Shares

Key Takeaways

• TSMC’s US-listed shares fell 1.80% to $422.25 on October 15, despite stronger earnings and an upbeat fourth-quarter revenue outlook.
• Third-quarter net profit increased 68.7%, while management raised its 2026 revenue growth outlook to around 44% in US dollar terms.
• Investors weighed strong advanced-chip demand against margin pressure, rising investment requirements and a broader semiconductor sell-off.

TSMC Shares Retreat Despite Strong Earnings

Taiwan Semiconductor Manufacturing’s US-listed shares closed lower on Thursday, October 15, as another record earnings report failed to reverse selling pressure across semiconductor stocks.

TSMC’s American depositary receipts fell 1.80% to $422.25. Trading volume exceeded 22 million shares, roughly twice the recent daily average. The shares subsequently edged higher in extended trading.

The decline highlighted the gap between TSMC’s operating performance and sentiment toward the wider AI investment cycle. Its results showed continued demand for advanced manufacturing capacity, but investors remained concerned about the cost of funding AI infrastructure and the returns that spending will generate.

The Philadelphia Semiconductor Index fell 0.9%, extending its losing streak to seven sessions. TSMC’s positive results therefore arrived during a sustained reduction in appetite for chip stocks.

Third-Quarter Profit Rises 69%

source: Financial Results -2026Q3

TSMC reported third-quarter net income of NT$763.06 billion, up 68.7% from a year earlier. Revenue reached NT$1.494 trillion, an increase of 50.9% in local currency.

In US dollar terms, revenue totalled $46.72 billion, up 41.2% year over year. Diluted earnings were NT$29.43 per ordinary share, equivalent to $4.60 per ADR. The distinction between currencies matters: exchange-rate movements mean the company’s dollar revenue growth differs from its reported growth in Taiwan dollars.

Both sales and ADR earnings exceeded market expectations. Analysts had expected revenue of approximately $45.67 billion and earnings of about $4.46 per ADR.

The results reinforced TSMC’s central role in the advanced-chip supply chain. However, an earnings beat does not automatically produce a share-price gain. Investors also assess how much growth was already anticipated and whether the outlook justifies the spending required to deliver it.

Fourth-Quarter Guidance Points to Further Growth

TSMC forecast fourth-quarter revenue of $52.3 billion to $54.3 billion. The $53.3 billion midpoint implies approximately 14% sequential growth, extending the company’s expansion into the final quarter of 2026.

Management also raised its full-year revenue growth outlook to around 44% in US dollar terms, supported by continued demand for leading-edge technologies.

That guidance provides an important counterweight to the weakness in semiconductor shares. TSMC’s near-term sales outlook continues to indicate expansion, even as investors question the longer-term economics of the AI infrastructure buildout.

For market participants, these are separate issues. Strong orders can support a chip manufacturer’s revenue while concerns about customer financing, future utilisation and investment returns weigh on its valuation.

The next test will be whether customer spending plans continue to translate into sustained manufacturing demand as additional capacity becomes available.

Gross Margin Pressure Draws Attention

Profitability was one area where the outlook offered a more measured message.

TSMC reported a third-quarter gross margin of 66.4%. Its fourth-quarter guidance range of 65% to 67% has a midpoint of 66%, implying a sequential decline of 40 basis points, or 0.4 percentage points.

Management linked the expected pressure primarily to the steep ramp-up of 2-nanometre production and dilution from overseas factories. Productivity gains and cost improvements are expected to provide a partial offset.

The figures show why revenue growth alone does not settle the investment debate. New manufacturing technologies can strengthen TSMC’s competitive position while initially increasing production costs.

Investors will therefore be watching how quickly new capacity reaches efficient operating levels. A stronger sales mix and better factory utilisation could help absorb those costs, while a slower ramp-up could keep margins under pressure.

Higher Spending Complicates the 2027 Outlook

TSMC maintained a 2026 capital expenditure budget of $60 billion to $64 billion. Management also indicated that investment over 2026–2028 would be significantly higher than in the preceding three years.

Although AI demand remains strong, the company adopted a prudent planning stance toward 2027, citing macroeconomic uncertainty and pressure on consumer and price-sensitive markets from rising component costs.

That combination creates a more complex outlook than the headline earnings growth suggests. Capacity expansion supports future sales, but it also increases the importance of accurate demand planning.

The broader concern is whether spending across the AI supply chain can maintain its current pace. Financing costs matter because more expensive capital can make large infrastructure projects harder to fund and raise the returns investors expect from them.

TSMC’s near-term guidance remains strong. The uncertainty centres on how demand, spending and profitability develop beyond the current reporting period.

Terafab Discussions Depend on Operational Control

Potential participation in Elon Musk’s Terafab project added another strategic issue to the earnings discussion.

CEO C.C. Wei said any facility producing TSMC chips would need to be operated by TSMC. The company remains open to different ownership or partnership arrangements, but operational control is a condition of its involvement.

The discussions should therefore be treated as a possible expansion opportunity rather than a confirmed manufacturing agreement. Until commercial terms, investment commitments and production arrangements are established, their financial contribution remains uncertain.

Needham Raises Its TSMC Price Target

Needham analyst Charles Shi maintained a Buy rating and increased his target for TSMC’s ADRs to $560 from $530 following the results.

The target increase illustrates how a positive longer-term assessment can coexist with near-term share-price weakness. Analyst targets reflect assumptions about future earnings and valuation; daily trading also responds to sector positioning and changes in market risk appetite.

TSMC’s latest report strengthened the evidence for continued advanced-chip demand. Its share-price decline nevertheless showed that investors want greater confidence in margins, capital spending returns and the durability of the AI investment cycle before rewarding that growth.
