Despite posting record results in Q2 2021, TSMC's stock price plummeted 5.5% on the day of announcement due to net income falling short of market expectations.

TSMC announced its Q2 2021 consolidated operating results on the 15th. According to the results, Q2 revenue on a U.S. dollar basis was $13.29 billion (NT$372.145 billion) on a consolidated basis, representing a 28% increase year-over-year and a 2.9% increase quarter-over-quarter. Net income reached approximately $4.804 billion (NT$134.359 billion), up 11.2% compared to the same period last year.

Despite these record results, net income fell short of financial market expectations of NT$136.1 billion (approximately $4.847 billion in U.S. dollars). As a result, TSMC's stock price plunged 5.5% on the day of announcement. TSMC's current market capitalization stands at $598.214 billion.

In Q2, TSMC's 5-nanometer shipments accounted for 18% of total wafer revenue. 7-nanometer represented 31%, and advanced technology defined as 7-nanometer and above accounted for 49% of total wafer revenue.

Wendell Huang, TSMC's Senior Vice President and Chief Financial Officer, stated, "Our Q2 business was primarily driven by sustained strength in HPC and automotive-related demand," and added, "As we enter Q3 2021, we expect business to be supported by strong demand for the industry's leading 5nm and 7nm technologies, driven by all four growth platforms: smartphones, HPC, IoT, and automotive applications."

TSMC projected Q3 2021 revenue to fall between $14.6 billion and $14.9 billion in U.S. dollars.

Additionally, TSMC announced that it will commence trial production of 4-nanometer process technology this year, will employ FinFET process for 3-nanometer, and will utilize GAA (Gate-All-Around) technology for 2-nanometer.
