Applied Materials vs. Taiwan Semiconductor Manufacturing: Which Tech Stock Is a Better Buy in 2026?

As global demand for high-performance chips accelerates, investors face a choice between equipment providers and manufacturers. Deciding whether to buy Applied Materials (NASDAQ:AMAT) or Taiwan Semiconductor Manufacturing (NYSE:TSM) requires weighing growth against valuation.

Applied Materials provides the specialized machinery used to build chips, while Taiwan Semiconductor Manufacturing acts as the primary foundry for the world's most advanced chip designers. Both are essential pillars of the modern tech economy, but they occupy different stages of the supply chain. This comparison explores their financial health and risk profiles to help you choose the right fit.

The case for Applied Materials

Applied Materials provides critical materials engineering solutions and manufacturing systems for the semiconductor industry and display markets. It serves a global client base, providing the specialized tools necessary for producing chips used in everything from smartphones to artificial intelligence. Customer concentration like this adds a layer of risk to the business, as two major customers accounted for nearly 19% and 15% of net revenue in fiscal 2025. The company also maintains a significant presence in China, Taiwan, and Korea, which makes the business sensitive to regional geopolitical developments and export regulations.

In 2025, revenue reached nearly $28 billion, representing growth of roughly 4.4% over the previous year. The company reported net income of close to $7 billion for the same period.

While revenue grew, the net margin of approximately 25% was slightly lower than the 26% reported in 2024. This indicates that while the company is expanding its top-line sales, the percentage of revenue kept as profit has narrowed slightly.

As of its October 2025 balance sheet, the debt-to-equity ratio was roughly 0.3x, a measure of total debt relative to shareholders' equity. The current ratio, which measures the ability to pay short-term debts with current assets, stood at approximately 2.6x.

During 2025, the company generated free cash flow of nearly $5.7 billion, which is calculated as cash flow from operations minus capital expenditures.

The case for Taiwan Semiconductor Manufacturing

Taiwan Semiconductor Manufacturing is the world's largest dedicated semiconductor foundry, manufacturing chips for a vast array of global clients. It operates a network of advanced manufacturing facilities across Taiwan, the United States, Japan, and Europe. This scale enables it to lead the industry in producing the smallest and most efficient chips. By focusing exclusively on manufacturing rather than design, it has become an indispensable partner for many of the largest names in the technology sector.

In 2025, revenue reached approximately $121 billion, representing roughly 38% growth over the previous year. The company reported a net income of nearly $54 billion for the fiscal year. Its net margin was approximately 45%. This reflects a high level of profitability relative to its total sales during a period of rapid expansion.

As of its December 2025 balance sheet, the debt-to-equity ratio was close to 0.2x, representing total debt relative to shareholder equity. The current ratio was approximately 2.5x, suggesting the company has ample liquid assets to cover short-term liabilities. Free cash flow for 2025 reached nearly $32 billion, which is defined as cash flow from operations minus capital expenditures.

Risk profile comparison

Applied Materials faces significant risks from U.S. export controls and trade policies, especially concerning its operations in China. The company recently paid a $252 million penalty to the U.S. Department of Commerce to settle allegations of illegal exports. Furthermore, the business is highly cyclical and sensitive to shifts in capital spending and technological obsolescence.

Taiwan Semiconductor Manufacturing faces risks related to geopolitical tensions, particularly given the concentration of its advanced facilities in Taiwan. The company also requires substantial capital expenditures to maintain its technological lead over rivals such as Intel.

Valuation comparison

Taiwan Semiconductor Manufacturing currently offers a lower multiple on Forward P/E, while Applied Materials carries a lower P/S ratio based on sales over the past twelve months.

Which stock would I buy in 2026?

Both companies are posting solid growth amid growing investment in AI infrastructure. I would buy TSMC because of its dominant competitive position as a global chip foundry and its attractive valuation relative to growth.

Applied Materials has seen accelerated revenue growth over the past year. As of Q2 2026, TTM revenue is up 7.8% year over year, ahead of the 4% pace in 2025. But the stock trades at a premium forward earnings multiple of 29x, with analysts projecting 17% annualized earnings growth over the long term.

TSMC is growing significantly faster, earns a higher profit margin, and yet trades at a lower forward earnings multiple of 22x. Without TSMC, there would be no AI boom, because it controls 73% of the global chip foundry market as of Q2 2026, according to Counterpoint Research. Analysts expect TSMC's earnings to grow at an annualized rate of 27% in the coming years.

One caveat for TSMC's lower valuation is the risk inherent in its supply chain, which is dependent on one key supplier for the lithography equipment to make advanced chips. There is also long-term uncertainty due to geopolitical risks in Asia.

It's a trade-off between strong growth and industry dominance and the probability that these risks manifest at some point. I'd personally be willing to accept that risk in exchange for superior returns as the AI boom continues.
