TSMC Posts Record Q2 Profit, Lifts Outlook as AI Demand Propels Semiconductor Sector

Taiwan Semiconductor Manufacturing Company (TSMC), the world’s largest contract chipmaker, delivered blockbuster second-quarter results, reinforcing its status as the bellwether for the global semiconductor industry. The company reported record-breaking net income of NT$398.3 billion ($13.5 billion), up 60.7% year over year and ahead of analyst expectations, driven by strong demand for artificial intelligence (AI) and high-performance computing (HPC) chips. The solid performance, which came despite currency headwinds and tariff uncertainty, sent TSMC’s U.S.-listed shares up over 4% in premarket trading and provided a tailwind to the broader tech complex.

For investors, the results are a key signal that AI-driven semiconductor demand remains robust. TSMC’s earnings not only validate the market strength seen by customers like Nvidia and Apple but also offer a broader read-through on the health of the semiconductor supply chain. With advanced chip orders showing no signs of slowing, the report is giving the Philadelphia Semiconductor Index (SOX) a lift and helping support equity markets overnight.

TSMC’s Q2 revenue rose 39% year over year to NT$933.8 billion, or $30.07 billion in U.S. dollar terms, up 44.4% from the prior year and nearly 18% sequentially. The company beat LSEG SmartEstimates on both the top and bottom lines, with net income topping NT$398 billion versus expectations around NT$378 billion. Driving that growth was continued momentum in AI and HPC chips, which now account for 60% of total revenue, up from 52% in the same quarter last year.

A closer look at the platform mix reveals that HPC and smartphone segments represented 60% and 27% of net revenue, respectively. IoT and automotive were stable contributors at 5% each, while digital consumer electronics (DCE) added 1%. Sequential growth was strongest in DCE (+30%) and IoT (+14%), while automotive was flat. Regionally, North America remains TSMC’s dominant market, contributing 75% of revenue, followed by China and Asia Pacific at 9% each.

In terms of manufacturing nodes,

That said, gross margins dipped modestly to 58.6%, down from 58.8% in Q1, mainly due to the appreciating Taiwan dollar and margin dilution from overseas fabs. Management guided Q3 gross margins to come in between 55.5% and 57.5%, noting that foreign exchange pressure and startup costs from U.S.-based fabs will weigh on profitability. Operating margin improved to 49.6%, aided by operating leverage and disciplined cost controls, while net profit margin reached 42.7%.

Looking ahead, TSMC now expects full-year 2025 revenue growth of approximately 30% in U.S. dollar terms, up from its prior forecast of “mid-20s” growth. Q3 revenue is forecasted between $31.8 billion and $33.0 billion, representing roughly 38% year-over-year growth and 8% sequential growth at the midpoint. The company also reaffirmed its long-term guidance that AI chip revenue will double in 2025 and grow at a compound annual rate of 40–45% for the next five years.

Management struck a confident tone on the earnings call, pointing to resilient demand from leading-edge process technologies and a broad-based AI buildout across industries. CFO Wendell Huang said the Q2 strength was supported by “continued robust AI and HPC-related demand,” while CEO C.C. Wei emphasized that “mass production began in Arizona in Q4 of last year” and that construction of TSMC’s second U.S. fab is now complete. The company plans to manufacture 2nm chips in Arizona by 2028 as part of its $165 billion U.S. investment.

Despite the bullish operational outlook, tariff-related uncertainty remains a looming macro overhang. While semiconductors have been exempt from the latest round of U.S. tariffs, TSMC acknowledged that new levies—particularly those floated by former President Trump—could pose future risks. CEO Wei stated that “so far, we have not seen any change in customer behavior,” but conceded there is “uncertainty and risk from the potential impact of tariff policies,” particularly in Q4 and beyond. The Commerce Department is reportedly investigating whether national security justifies broader tariffs on chips.

Further complicating the macro picture, U.S. export controls have restricted TSMC’s business with China, as well as that of its major customers

Analysts remain broadly positive on the stock despite some near-term margin compression. Jefferies noted prior to the report that margins could trend toward 55–56%, consistent with Q3 guidance. Still, most agree the AI supercycle is in its early innings, and TSMC stands as one of the clearest beneficiaries. Counterpoint Research’s Brady Wang noted that “surging demand from the AI boom is highly sustainable in the near term,” given the continued shift toward smaller process nodes and more efficient transistor designs.

In sum, TSMC’s Q2 results reaffirm its leadership in global chipmaking, particularly in AI and advanced process technologies. The company is executing well against a backdrop of macro uncertainty, with demand strong enough to lift both its full-year revenue outlook and investor confidence. While FX pressure and tariff uncertainty remain watch points, the broad message from TSMC’s report is clear: the semiconductor cycle remains alive and well—especially for those playing at the bleeding edge.
