Taiwan Semiconductor Manufacturing (TSM) announced May 2026 sales of NT$416.98 billion, equivalent to approximately $13.19 billion. This represents a substantial 30.1% increase compared to the corresponding month in 2025, alongside a modest 1.5% sequential gain from April.

Taiwan Semiconductor Manufacturing Company Limited, TSM

Robust appetite for artificial intelligence processors remains the primary catalyst driving these impressive figures. TSMC serves as the exclusive manufacturing partner for industry giants including Nvidia and Apple, both central players in the accelerating AI semiconductor revolution.

For the opening five months of 2026, the company’s cumulative revenue reached NT$1.96 trillion—representing a 30.0% surge versus the comparable 2025 timeframe.

Yet despite this compelling financial performance, TSM stock retreated roughly 2.2% during Wednesday’s Taiwan trading session. Market analysts suggest profit-taking following an extended rally likely explains the pullback.

In its April outlook, TSMC projected second-quarter revenue between $31.4 billion and $32.4 billion. The May results indicate the company remains firmly on track to achieve that forecast.

Examining TSMC’s Valuation Metrics

TSMC currently trades at a price-to-earnings multiple of 35.55x, representing a premium versus its historical trading range. This elevated valuation reflects market expectations for sustained expansion ahead.

According to GuruFocus analysis, TSMC earns a GF Score of 94 out of 100. The chipmaker achieves perfect 10/10 ratings in both profitability and growth categories, complemented by a 9/10 financial strength assessment. These metrics paint a picture of fundamental excellence.

The company controls approximately 70% of the worldwide contract semiconductor foundry industry. Its customer roster—featuring Apple, Nvidia, AMD—represents the cutting edge of advanced chip design.

Notable Insider Transaction Patterns

One element warranting attention: insider selling activity has been evident. Throughout the most recent three-month period, TSMC insiders executed net sales totaling $14 million, with zero insider purchases documented during that interval.

While this doesn’t negate the compelling revenue narrative, it represents a signal that market participants typically monitor with interest.

TSMC maintains a Piotroski F-Score of 8, indicating exceptional balance sheet quality. The company’s market capitalization stands at roughly NT$2.22 trillion, translating to approximately $71.5 billion.

Established in 1987, the company has constructed a virtually irreplaceable position within global semiconductor manufacturing infrastructure.

TSMC’s April guidance calling for $31.4 billion to $32.4 billion in second-quarter revenue was delivered amid considerable global trade tensions and tariff-related uncertainties. The May performance suggests these potential obstacles haven’t materially impacted order flow.

With NT$1.96 trillion recorded through the first five months of 2026, TSMC maintains clear momentum toward its full-year objectives.
