Taiwan Semiconductor Manufacturing has already told investors most of what it earned last quarter. What it has not told them is what it expects next, and that is the part the market will trade on when the company reports third-quarter results on Oct. 15 and holds its earnings call at 2 a.m. Eastern.
The revenue figure is public. TSMC said last week that September sales rose 54.6% from a year earlier to NT$511.86 billion, lifting quarterly revenue to a record NT$1.49 trillion, or roughly $46.7 billion. That is a gain of about 50% from a year earlier, and it beat both the company’s own guidance and the consensus of analysts. Monthly disclosure is a feature of the Taiwanese market, and it has turned the quarterly report into a test of guidance rather than a surprise on the top line.
Profit is where the forecast sits. Analysts polled by LSEG, in an estimate that gives more weight to historically accurate forecasters, expect net income of about NT$746 billion, or $23 billion, up 65% from a year earlier, according to Reuters. Anything above NT$707 billion would be the company’s highest quarterly profit and its sixth consecutive record quarter, extending a run of 11 straight quarters of growth.
Those numbers rest on a single customer category. TSMC builds the accelerators that run artificial intelligence workloads for Nvidia and the processors inside Apple’s devices, and it is the only manufacturer able to produce the most advanced chips at the volume its customers require. That position has made it Asia’s most valuable company, with a market value of about $2.1 trillion, nearly double that of Samsung Electronics.
The pressure point is capacity of a different kind. Building an AI accelerator requires advanced packaging that fuses processors and memory into a single unit, a step known as CoWoS, and demand for it has outpaced supply for more than a year. Analysts said they will listen for how much of that capacity TSMC intends to add and when it will be ready, because the figure sets a ceiling on how many chips Nvidia can ship next quarter.
Guidance will carry more weight than the results. Charlie Chan of Morgan Stanley expects the company to raise its full-year revenue growth forecast into the low-to-mid 40% range from more than 40%, citing demand for its three-nanometer process. In July, TSMC lifted its capital spending plan for the year to between $60 billion and $64 billion. A further increase would signal that the company sees the spending cycle extending into 2027.
Margins are the second question. Gross margin on the most advanced nodes is expected to hold near 50%, a level that reflects both pricing power and the expense of equipment that must be replaced as each generation of chips arrives. A slip below that mark would suggest that rising costs, or the price of building plants overseas, are eating into the advantage that comes from leading the market.
Overseas plants are the third. TSMC is investing $265 billion in Arizona, and Reuters has reported that it is evaluating an additional site in Texas. Elon Musk said last week that his companies would build and operate an AI chip complex called Terafab, and that TSMC could sublease part of it. Analysts are divided on the timing, with one arguing that Texas could become necessary within five years given limited room in Arizona and another seeing little urgency while planned Arizona plants remain unbuilt.
The setup for the report is unusual. TSMC shares have risen 63% this year in Taipei, roughly in line with the 69% gain in the broader Taiwanese market, which means the stock has tracked the AI trade rather than lagged it. When a company’s shares move with a rally, the earnings call becomes a place to confirm rather than to surprise, and the penalty for a cautious word on fourth-quarter demand is larger than the reward for a beat that analysts already expect.
That is the bar the results will meet. The week before the report brought a pullback in chip stocks, a sign that investors have started to ask how long the spending can continue at its present rate. TSMC’s capital expenditure plan and its comments on customer commitments are the nearest available evidence, and its order book is treated as an early indicator for Nvidia’s next quarter. The call will be read as a verdict on the supply chain rather than on one manufacturer.
Executives will also face questions about concentration. Nearly all of the growth in the company’s most advanced business comes from a handful of customers spending money raised in the equity and debt markets. If that spending slows, the effect reaches TSMC through a shorter order book before it reaches anyone else, and the record profit analysts forecast for this quarter will have been earned at a point in a cycle whose length nobody has established.
The figure to watch arrives early. The guidance, not the profit, will tell investors whether demand for advanced chips is still building or has begun to level off, and TSMC’s answer will be repeated across an industry that has staked its spending plans on the same assumption.
