Three Key Variables Beyond Revenue
TSMC will hold its Q2 2026 earnings call on July 16 at 14:00 Taiwan time, entering a quiet period from July 6 to 15. As the world's largest pure-play foundry, TSMC serves mobile chip clients like Apple and Qualcomm while also processing AI accelerators, cloud custom chips, and high-performance computing (HPC) demand. The Q2 report will directly validate three questions: whether AI orders continue to be strong, whether 2nm ramp-up is on track, and how long the nearly 66% gross margin can be sustained.
Q1 Results and Q2 Guidance: Gross Margin Remains at High End
TSMC's Q1 delivered strong results: revenue of $35.9 billion, gross margin of 66.2%, and operating margin of 58.1%. In NT dollar terms, Q1 revenue reached NT$1.134103 trillion, net profit NT$572.48 billion, EPS NT$22.08; revenue grew 35.1% YoY and net profit surged 58.3% YoY. Q2 guidance remains at a high level: revenue between $39.0 billion and $40.2 billion, gross margin between 65.5% and 67.5%. Monthly revenue signals strong demand: May revenue of NT$416.975 billion, up 30.1% YoY; January–May cumulative revenue of NT$1.961804 trillion, up 30.0% YoY. Morgan Stanley expects TSMC's Q2 gross margin to reach 67.4%, at the high end of guidance. The market will focus on whether actual gross margin can hold above 65% and management's tone on second-half profitability.
AI/HPC Driving Demand and Capex to New Heights
TSMC's strongest growth engine remains AI and HPC. On the Q1 call, management described AI-related demand as "extremely robust" and raised its 2026 USD revenue growth forecast to over 30%. Revenue structure confirms this: HPC accounted for 61% of Q1 revenue, and 7nm and below advanced nodes contributed 74% of wafer revenue. AI chip demand also pushes up advanced packaging capacity, with CoWoS and SoIC as key expansion areas. TSMC has guided full-year 2026 capex to the high end of $52–56 billion, indicating that management sees a long-term capacity gap driven by AI/HPC, not short-term fluctuations. However, capex near the upper bound is a double-edged sword: it widens the lead when demand is strong but quickly translates into margin pressure if demand softens.
2nm Ramp-Up and Second-Half Outlook
2nm is an even more critical variable for TSMC's coming years. Management has stated that N2 entered high-volume production in Q4 2025 and is ramping in multiple phases at Hsinchu and Kaohsiung, with demand from smartphones and HPC/AI. The market's focus is not whether 2nm is in production, but how fast supply can expand, whether yield improves as planned, and whether initial customer demand can cover the heavy capex. TSMC expects N2/A16 capacity to ramp rapidly from 2026 to 2028, with a CAGR of approximately 70%. The July 16 earnings call will be key not only for Q2 guidance delivery but also for management's comments on second-half AI/HPC demand, advanced packaging capacity, 2nm ramp progress, capex plans, and gross margin outlook. If TSMC maintains a strong demand view and gross margin stays within the 65.5%–67.5% range, confidence in the AI hardware chain will continue to be supported. If management signals more caution on orders, inventory, or cost pressure, investors will reassess how long the AI supply chain's high growth can last.
