Taiwan Semiconductor Manufacturing has once again delivered a report card that exceeded expectations, providing a clear answer to the recent market debate over whether the AI investment cycle has peaked.

The company not only maintained high growth in Q2 revenue and profit but also, in a rare move, significantly raised its full-year revenue and capital expenditure guidance. It explicitly stated that investment intensity will continue to increase in the coming years, sending a strong signal that AI demand remains in a phase of rapid expansion.

For Wall Street, management's outlook on future demand is more critical than the quarterly results themselves. With the upward revision of capital expenditure, reinforced growth expectations for AI accelerators, and the ongoing expansion of advanced capacity, market confidence in the duration of the AI infrastructure boom cycle has been reaffirmed.

Several investment banks believe that this upward revision of its full-year outlook by Taiwan Semiconductor Manufacturing not only signifies a strengthening of its own growth momentum but will also boost confidence across the entire AI semiconductor supply chain. Sectors including semiconductor equipment, advanced packaging, and memory are all expected to continue benefiting. Although the gross margin guidance is slightly below some optimistic forecasts, institutions widely view this as reflecting temporary pressures from new process node ramps, which does not alter the fundamental long-term upward trajectory of AI demand.

Solid Performance, Full-Year Growth Outlook Revised Up Again

Taiwan Semiconductor Manufacturing raised its 2026 capital expenditure guidance from $52-56 billion to $60-64 billion, an increase of over 10%. Its full-year US dollar revenue growth guidance was also raised from "over 30%" to "over 40%", significantly exceeding the market's general expectation of 35-40%.

Chairman C.C. Wei stated during the earnings call that AI demand remains "extremely strong" and announced an additional $100 billion investment in Arizona, USA, bringing the total cumulative investment there to $265 billion.

UBS analyst Crystal Hsu noted that the rare move by Taiwan Semiconductor Manufacturing to raise its full-year capex target in Q2 further strengthens market confidence in the AI supply chain's strength, implying that semiconductor equipment manufacturers are poised to continue benefiting.

Gross Margin Slightly Below Optimistic Forecasts, but Profitability Remains at Historical Highs

The gross margin was 67.7%, slightly above the market consensus of 67.6% but below J.P. Morgan's previous forecast of 69.5%. The operating margin broke the 60% threshold for the first time, reaching 60.3%, an improvement of over 10 percentage points year-over-year. Earnings per share were NT$27.25, about 10% higher than J.P. Morgan's forecast.

Morgan Stanley analyst Charlie Chan pointed out that the gross margin being below some high market expectations was mainly due to the early booking of depreciation for the 2-nanometer process and the dilution effect from overseas fab ramps. J.P. Morgan characterized this as a one-time margin reset but believes the long-term gross margin can still be stably maintained above 60%.

Regarding the Q3 outlook, the company expects revenue to grow approximately 12% sequentially, falling within Morgan Stanley's previously forecasted range of 10-15%. J.P. Morgan anticipates that the mass production of 2-nanometer in the second half will bring about 300-400 basis points of gross margin pressure, but this will be partially offset by continued improvements in the profitability of 3-nanometer products. Morgan Stanley noted that the company's Q3 gross margin guidance of 66% is below its own forecast of 67.5% and also falls short of some buy-side institutions' optimistic expectations of close to 70%.

Nevertheless, both institutions believe this does not change the company's long-term growth thesis and suggest investors use any stock price volatility driven by margin expectation adjustments as an opportunity to accumulate shares. J.P. Morgan expects that, driven by the upward revision of the full-year revenue guidance, market forecasts for Taiwan Semiconductor Manufacturing's 2026 EPS could be raised by 2-3%, with even more significant upside potential for 2027-2028 earnings estimates.

UBS also stated that while the company's margin guidance is relatively conservative, the market generally believes management is prioritizing customer relationship stability and will smooth out margins through subsequent product mix optimization, with no change to the long-term fundamentals.

Significant Capex Increase Extends AI Demand Visibility to 2030

The substantial increase in capital expenditure was the most closely watched aspect. CFO Wendell Huang stated that the company maintains high confidence in the long-term trend of AI development, and capital expenditure over the next three years will be significantly higher than in the past three years.

UBS noted that it is historically rare for Taiwan Semiconductor Manufacturing to raise full-year capex in Q2, making this revision particularly significant. J.P. Morgan believes this round of increased capex is primarily for advance equipment purchases, expanding 3nm and 5nm capacity, building new fabs, and coping with rising equipment costs.

Although the company did not disclose specific capex figures for the next three years, management clearly stated that future capital investment will increase further. This suggests that J.P. Morgan's current forecasts of $78 billion for 2027 and $84 billion for 2028 still have room for upward revision.

Positive signals were also released on the demand side. Management indicated that cloud computing customers continue to increase capital expenditure, and the compound growth trajectory for the AI accelerator business from 2024 to 2029 has already exceeded the previously forecasted mid-to-high 50% range.

J.P. Morgan believes that, based on customer orders and end-demand, new demand driven by Agentic AI is rapidly expanding, covering not just AI accelerators but also CPUs, networking chips, HBM, and other infrastructure. The related boom cycle is expected to extend into 2029-2030.
