• TSMC's net income was 325.3 billion Taiwanese dollars ($10.1 billion) over the July-September quarter, surpassing an LSEG estimate of $300.2 billion Taiwanese dollars.
• Net revenue came in at $23.5 billion in the third quarter, up 36% year-on-year.
• TSMC is the world's largest producer of advanced chips, serving clients such as Apple and Nvidia.

Taiwan Semiconductor Manufacturing Company on Thursday reported a 54% hike in net profit, as global chipmakers continue to benefit from demand boosted by AI applications.

The company's net income was 325.3 billion Taiwanese dollars ($10.1 billion) over the July-September quarter, surpassing an LSEG estimate of $300.2 billion Taiwanese dollars cited by Reuters.

TSMC is the world's largest producer of advanced chips, serving clients such as Apple and Nvidia.

Net revenue came in at $23.5 billion in the third quarter, up 36% year-on-year, with TSMC's gross margin rising to 57.8% over July-September, compared with 54.3% in the same period of last year.

In the third quarter, "our business was supported by strong smartphone and AI-related demand for our industry leading 3nm and 5nm technologies," TSMC said in a statement, referencing its semiconductor nodes.

In an earnings call, TSMC Chairman and CEO C.C. Wei stressed that AI demand is "real" and that the company has experienced the "deepest and widest growth of anyone in this industry," as a result.

"We have talked to our customers all the time, including our hyperscaler customers who are building their own chips. And almost every AI innovator is working with TSMC," he said, according to a call transcript produced by FactSet.

The company's Taipei-listed shares have soared nearly 80% year-to-date, outpacing the 28.57% gains of the broader market over the same period.

TSMC now anticipates its capital expenditure for this year will pick up to slightly higher than $30 billion, it said during its earnings call. The firm's capex costs edged higher to $6.4 billion in the third quarter, versus $6.36 billion across the three preceding months.

The Taiwanese chipmaker, whose advanced chips are vital to a swathe of products ranging from smartphones to AI applications, has been increasing its manufacturing presence worldwide, carrying out a vast overseas investment of $65 billion for three chip plants in Arizona to meet U.S. demand, as well as opening its first factory in Japan earlier this year.

TSMC's earnings beat comes the same week as Netherlands-based ASML, which supplies machines to the Taiwanese company, issued a lower-than-expected forecast of net sales, sending shares tumbling.

Some market participants have questioned the long-term resilience of the AI boom and the return on increasing investments in the technology sector — while Young Liu, CEO and chairman of key Apple supplier Foxconn, told CNBC last week that the AI frenzy "still has some time to go," as advanced language models evolve with each new iteration.
