TSMC Reports Record Profits Amid Surging AI Demand, Faces Capacity Constraints
Taiwan Semiconductor Manufacturing Company (TSMC) has reported a significant increase in its fourth-quarter profit and revenue, exceeding market estimates. This impressive performance is primarily driven by robust demand for artificial intelligence (AI) chips and advanced computing. The company also registered a substantial year-over-year revenue increase in January.
Amid this strong growth, TSMC and its partners have identified emerging capacity constraints across the supply chain, particularly for advanced chip production. This situation is prompting customers to secure long-term agreements to ensure future supply.
TSMC has reported a significant increase in its fourth-quarter profit and revenue, exceeding market estimates, primarily driven by robust demand for artificial intelligence (AI) chips and advanced computing.
Financial Performance Overview
TSMC reported a 35% increase in fourth-quarter profit, reaching a new record. For the December quarter, net income was NT$505.74 billion, surpassing anticipated figures. Revenue for the same period increased by 20.5% year-over-year, reaching NT$1.046 trillion ($33.73 billion), exceeding average projections. This marks the company's eighth consecutive quarter of year-over-year profit growth.
In January, TSMC's revenue surged by 36.8% year-over-year, reaching NT$401.26 billion. Following these positive reports, shares of TSMC increased by approximately 3% in premarket trading, while shares of ASML Holding NV, a key supplier, rose about 6%.
For the current quarter, TSMC executives project revenue to range between $34.6 billion and $35.8 billion. This represents an approximate 4% sequential increase and a 38% year-over-year rise at the midpoint.
Drivers of Growth: AI and Advanced Technologies
The demand for AI chips and high-performance computing (HPC) has been a primary catalyst for TSMC's growth. The company, a major manufacturer of advanced AI accelerators for firms like Nvidia and AMD, reported that its HPC division, encompassing AI and 5G applications, accounted for 55% of total sales in the October-December quarter. Smartphone demand contributed 32% of sales, with specific support from products like the iPhone 17.
Advanced chips, defined as those measuring 7-nanometer or smaller, constituted 77% of total wafer revenue in the fourth quarter. For the full year 2025, these advanced chips are projected to make up 74% of revenue, an increase from 69% in 2024. TSMC has also begun mass production of its 2-nanometer offerings, with further expansion planned for this year.
Capacity and Supply Chain Challenges
Despite strong demand, the surging growth in AI chip production has led to identified capacity constraints within TSMC's operations and the broader supply chain. Broadcom, a manufacturing partner, indicated that TSMC is nearing its production capacity limits due to the extensive buildout of AI infrastructure. While TSMC plans to increase capacity through 2027, this expansion is anticipated to create a bottleneck in the supply chain during 2026.
Constraints extend beyond semiconductors to other sectors, including the laser space and printed circuit boards (PCBs). Lead times for PCBs used in optical transceivers have reportedly extended from approximately six weeks to six months, with both Taiwanese and Chinese PCB suppliers experiencing capacity limits.
Investors have also expressed concerns regarding whether the projected capacity might exceed actual usage, and market analysts have noted issues related to the interconnected nature of some data center investments. Potential challenges identified by TSMC's Chairman and CEO, C.C. Wei, include global tariff policies for 2026 and memory shortages that could affect demand for consumer electronics. Wei stated that high-end smartphones are less susceptible to memory price fluctuations.
Future Outlook and Strategic Initiatives
TSMC's Chief Financial Officer, Wendell Huang, stated that business is expected to be supported by continued strong demand for leading-edge process technologies and increasing profit margins.
The company plans to significantly increase its capital expenditure, projecting between $52 billion and $56 billion for 2026, an increase from $40.9 billion in 2025 (revised from previous estimates of $40 billion to $42 billion for 2025). This investment reflects a focus on advanced products and capacity expansion.
In response to supply chain limitations, many customers are now entering into long-term agreements with suppliers, securing capacity commitments for periods of three to four years. This trend, also observed with memory chipmaker Samsung Electronics, aims to provide long-term supply security for customers and help suppliers manage demand fluctuations.
TSMC is also expanding its global manufacturing footprint with projects in Japan, Europe, and Arizona, where capacity expansion is accelerating. The company has indicated that overseas plants might operate at diluted margins compared to those in Taiwan.
