KEY POINTS
- TSMC posted Q1 net income of NT$572.48 billion ($17.8 billion), a 58% year-over-year increase that marks the company's fourth consecutive quarterly profit record.
- High-performance computing now accounts for 61% of TSMC's revenue, up from 40% two years ago, as hyperscaler AI infrastructure spending shows no sign of slowing.
- With Q2 revenue guided at $39 billion to $40.2 billion and capex pushed to the high end of a $52–$56 billion range, traders should watch whether TSMC can sustain margins above 65% as 2nm ramps.
TSMC delivered $17.8 billion in net income for the first quarter of 2026, a 58% jump that beat analyst estimates and cemented the Taiwanese chipmaker's position as the single most important earnings report in the AI supply chain. Revenue hit NT$1.13 trillion ($35.9 billion), up 40.6% year over year and 6.4% sequentially, extending an unbroken streak of quarterly records that now stretches back a full year.
The numbers are staggering not just in scale but in profitability. Gross margin climbed to 66.2%, nearly 400 basis points above the top of management's own guided range and a new high-water mark for a company that was running at roughly 53% just two years ago. Operating margin came in at 58.1%, also above the 54%–56% guide, confirming that TSMC's pricing power on advanced nodes is accelerating, not moderating.
AI Owns the Revenue Mix
The story behind the headline is the continued reshaping of TSMC's revenue composition. High-performance computing, the bucket that includes AI accelerators, data-center GPUs, and custom silicon for the hyperscalers, now represents 61% of total sales. Two years ago that figure was just north of 40%. CEO C.C. Wei described AI demand as "extremely robust" on the earnings call, a phrase TSMC management does not deploy lightly, and noted that demand continues to significantly outpace supply.
At the node level, 3nm shipments accounted for 25% of wafer revenue, up from 6% in Q3 2023. The 5nm node contributed 36% and 7nm another 13%, meaning that sub-7nm processes now generate roughly three-quarters of total wafer sales. The company's 2nm process entered volume production in Q4 2025 at its Hsinchu and Kaohsiung fabs, ahead of schedule, with initial yields reportedly exceeding internal expectations.
For traders, this mix shift is the key variable. Every percentage point that moves from mature nodes to leading-edge silicon carries a structurally higher margin profile. That dynamic explains how TSMC can post 66% gross margins while simultaneously ramping capital expenditures to the high end of a $52–$56 billion annual range. The capex is not dilutive because the revenue it generates returns at materially higher margins than the legacy business it displaces.
What the Guidance Says About the Rest of 2026
Management guided Q2 revenue to $39 billion–$40.2 billion, a roughly 10% sequential increase that would set yet another record. Full-year 2026 revenue is now expected to grow more than 30% in U.S. dollar terms, a forecast that implicitly assumes the AI infrastructure buildout does not lose steam in the back half.
The capex signal matters just as much. By pushing spending to the upper bound of the $52–$56 billion range, TSMC is telegraphing that capacity additions, particularly at the Arizona and Kumamoto fabs, are running ahead of plan. That is bullish for the broader AI supply chain because TSMC's capex is a leading indicator of wafer starts six to twelve months out. When TSMC spends more, it is because customers like Nvidia, Apple, AMD, and a growing roster of hyperscaler custom-chip programs have already committed the volume.
The Geopolitical Overhang
None of this happens in a vacuum. The U.S.–Iran conflict that flared again over the weekend after the seizure of the cargo vessel Touska in the Gulf of Oman has pushed crude to $88.54 WTI, adding an energy-cost headwind to every fab in the world. Meanwhile, export-control pressure on ASML, TSMC's critical equipment supplier, is tightening the screws on China-bound shipments. ASML's China sales fell to 19% of revenue in Q1 from 36% in Q4, and a proposed U.S. bill could restrict DUV sales further.
For TSMC, reduced Chinese access to advanced lithography equipment paradoxically strengthens its moat. The fewer fabs that can produce leading-edge chips, the more pricing power accrues to the fabs that can. But energy costs and supply-chain disruptions from the Strait of Hormuz situation bear watching, particularly if the ceasefire, set to expire Wednesday, collapses entirely.
The next data point that matters is TSMC's monthly revenue disclosure for April, due in early May. If the sequential ramp tracks guidance, the stock, already up sharply this year, has room to re-rate further. If the geopolitical backdrop deteriorates enough to shake hyperscaler capex confidence, the 66% gross margin becomes the floor traders need to hold in their models.
