Insights

Semiconductor equity analyst

TSMC shows very strong year-on-year revenue growth with modest FX hedging activity.

TSMC posted consolidated September 2025 net revenue of NT$330.98 billion, which is up 31.4% from September 2024, while January–September 2025 revenue of NT$2,762.96 billion is up 36.4% year-on-year. The slight 1.4 percent month-on-month decline versus August suggests normal monthly volatility rather than structural weakness given the strong year-on-year comparison.

The company also reports sizeable intercompany lending and guarantees that support expansion in China, the United States and globally. For example, TSMC China shows an outstanding lending amount of NT$14,567,300 thousand, and TSMC guarantees up to NT$457,787,235 thousand for TSMC Arizona. These figures highlight capital support for overseas fabs and subsidiaries.

On risk management, TSMC and its affiliates use foreign exchange forwards and futures. TSMC alone lists an outstanding notional amount of NT$210,103,177 thousand in forward contracts with a mark-to-market of (NT$1,144,690 thousand), while cumulative realized profit/loss on expired contracts is a gain of NT$1,877,252 thousand. All disclosed derivatives are non–equity-linked, indicating a focus on hedging currency and operational exposures rather than equity market speculation.
