TSMC Profit Surges 77% as Q2 Operating Margin Reaches 60.3%

Key Takeaways

• TSMC’s second-quarter net profit rose 77.4% year on year to a record NT$706.56 billion.
• Revenue increased 36% to NT$1.270 trillion, equivalent to approximately $40.2 billion.
• Operating margin reached 60.3%, comfortably exceeding the company’s 56.5%–58.5% guidance range.
• A NT$63.2 billion gain linked to Vanguard International Semiconductor boosted net income, but operating profit also climbed 65.4%.
• High-performance computing accounted for 66% of revenue, while advanced process nodes generated 77% of wafer sales.
• Updated revenue and capital expenditure guidance will be the next major catalyst for TSMC stock.

Record Q2 Earnings Put TSMC Stock Back in Focus

TSMC stock moved into focus after the world’s largest contract chipmaker delivered a substantially stronger second-quarter result than analysts had expected.

Net income for the three months ended June rose 77.4% from a year earlier to a record NT$706.56 billion, or approximately $22 billion. The result exceeded the NT$632.6 billion LSEG SmartEstimate by almost NT$74 billion. Diluted earnings reached NT$27.25 per share, equivalent to about $4.31 per American depositary receipt. Reuters also reported that this marked another record quarter for the company.

Revenue increased 36% year on year to NT$1.270 trillion, or around $40.2 billion. This was broadly consistent with TSMC’s earlier dollar-denominated guidance of $39 billion to $40.2 billion, reflecting continued demand for advanced processors used in artificial intelligence infrastructure.

The latest figures strengthen the view that AI-related semiconductor demand remains resilient. However, the scale of the profit increase also reflected a sizeable non-operating gain, meaning the headline growth rate should not be attributed entirely to TSMC’s manufacturing operations.

Operating Margin Delivers the Strongest Signal

TSMC’s margin performance arguably provided a clearer measure of its underlying business strength than the record net profit figure.

Gross margin reached 67.7%, slightly above the top of management’s previous 65.5%–67.5% forecast. Operating margin was even stronger at 60.3%, exceeding the upper end of the company’s 56.5%–58.5% guidance by 1.8 percentage points. TSMC’s official quarterly results page confirms the guidance ranges issued before the report.

Compared with the same period of 2025, gross margin expanded by 9.1 percentage points, while operating margin improved by 10.7 points. Operating expenses also declined to 7.8% of revenue from 9.1% a year earlier, indicating stronger cost control and operating leverage.

High factory utilisation, production efficiencies and a favourable product mix helped offset the margin dilution associated with TSMC’s expanding overseas manufacturing network. The company’s 67.7% gross margin was also its highest in more than two decades, according to The Wall Street Journal.

The result fell short of JPMorgan’s reported gross-margin estimate of 69.5%, which had assumed a larger contribution from operational efficiencies and premium-priced expedited orders. Nevertheless, the operating margin surpassed TSMC’s own forecast by a wide margin.

Core Operating Growth Remained Strong Despite One-Off Gain

Part of TSMC’s earnings surprise came from outside its core chip manufacturing business.

Non-operating gains reached NT$95.83 billion, more than three times the amount recorded in the previous quarter. This included approximately NT$63.2 billion related to the disposal and mark-to-market revaluation of shares in Vanguard International Semiconductor.

The gain materially increased reported net income and should be considered when comparing the headline profit growth with future quarters. It does not, however, undermine the strength of TSMC’s main operations.

Operating income increased 65.4% year on year to approximately NT$766.6 billion. The 60.3% operating margin therefore shows that stronger pricing, utilisation and production efficiency were already generating substantial earnings growth before the Vanguard-related gain was included.

Net profit margin rose to 55.6% from 42.7% a year earlier. While part of that expansion came from non-operating income, the improvement in operating margin confirms that the underlying business also became significantly more profitable.

AI and Advanced Process Nodes Drive Revenue Mix

TSMC’s revenue mix showed that AI and high-performance computing remained the main sources of growth during the quarter.

High-performance computing increased to 66% of total revenue from 61% in the first quarter. Revenue from the platform rose 20% sequentially, supported by demand for AI accelerators, data-centre processors, networking chips and custom silicon.

The company also disclosed revenue from its 2-nanometre process separately for the first time. The new technology contributed 3% of wafer revenue, suggesting that its commercial ramp is beginning to have a measurable impact.

Combined revenue from 2nm and 3nm technologies represented approximately one-third of wafer sales. Advanced technologies, defined as 7nm and below, accounted for 77% of wafer revenue.

This concentration gives TSMC considerable exposure to the AI investment cycle. It also creates risk if major cloud providers or chip designers reduce capital spending. For now, however, the latest revenue and margin figures indicate that demand for leading-edge production and advanced CoWoS packaging remains strong.

Updated Guidance Will Shape the TSMC Stock Outlook

The Q2 earnings beat supports the fundamental case for TSMC, but it does not guarantee that the stock will continue rising.

TSMC’s Taipei-listed shares had already gained approximately 59% in 2026 before the full earnings release, meaning investors had priced in significant AI-related growth. The market reaction may therefore depend more heavily on management’s outlook than on the historical quarter.

Bank of America analyst Haas Liu said supply-chain checks continued to indicate a strong AI demand pipeline. The analyst suggested TSMC could raise its full-year revenue-growth forecast from the existing expectation of more than 30%.

Investors will also watch whether the company increases its 2026 capital expenditure plan. TSMC previously guided to spending of $52 billion–$56 billion, while some analysts believe the figure could rise towards $58 billion.

Higher investment could signal management’s confidence in long-term demand and help expand constrained advanced-node and packaging capacity. However, larger spending commitments, the ramp-up of 2nm production and the growing contribution from overseas factories could make margins more difficult to maintain near 60%.

TSMC has delivered a strong operating quarter, but updated revenue, margin and capital expenditure guidance will determine whether the results are sufficient to support the stock’s elevated expectations.
