Micron vs. TSMC: Which AI Semiconductor Stock Is a Better Buy Now?
Read MoreHide Full Article
Key Takeaways
Micron posted strong Q3 FY2026 growth and guided for higher Q4 revenues on AI memory demand.
TSMC reported rising Q2 profit and revenues, with another quarter of sequential revenue growth expected.
Micron offers lower debt, higher ROE and a lower forward P/E than TSMC, supporting its appeal.
Micron Technology, Inc. (MU - Free Report) and Taiwan Semiconductor Manufacturing Company Limited (TSM - Free Report) , better known as TSMC, have both benefited from the artificial intelligence (AI) boom and have delivered impressive revenue growth and profitability in their latest quarterly results. However, if investors had to choose one stock, which should it be? Let’s see in detail –
The Bullish Case for Micron Stock
Micron is no longer considered a cyclical memory stock; instead, it has emerged as a vital supplier of AI infrastructure, having delivered strong quarterly results in recent times and boasting a strong outlook, fueled by robust AI memory demand.
In the fiscal third quarter of 2026, Micron reported revenues of $41.46 billion, up 74% sequentially, and expects even greater revenue growth in the fiscal fourth quarter of 2026, to $50 billion, according to investors.micron.com. This robust growth indicates that demand for Micron’s high-bandwidth memory chips, which are used in AI servers, remains strong.
Micron’s profitability improved as a result of an increase in demand for its memory products, along with strong pricing power. The company reported a gross margin of 84.6% in the fiscal third quarter, up from 37.7% a year ago. Additionally, a strong operating cash flow of $25.39 billion in the quarter has given Micron the much-needed financial flexibility to support further growth.
The Bullish Case for TSMC Stock
TSMC is known worldwide for manufacturing state-of-the-art semiconductor chips, supplying to tech behemoths like NVIDIA Corporation (NVDA - Free Report) , Broadcom Inc. (AVGO - Free Report) and Intel Corporation (INTC - Free Report) , to name a few. Being the leader in producing advanced chips has positioned TSMC at the center of the rapidly expanding AI ecosystem, supporting sustained future growth.
TSMC’s profits are growing much faster than revenues. The company reported net income of NT$706.56 billion in the second quarter ended June 30, 2026, up 77.4% year over year and 23.4% sequentially, according to investor.tsmc.com. The contract-chipmaker reported revenues of NT$1.27 trillion in the second quarter, up 36% year over year and 12% quarter over quarter. The strong results reflect stable demand for TSMC’s advanced chips, which continues to drive growth despite the company’s massive scale.
TSMC’s management expects another quarter of double-digit sequential revenue growth in the third quarter. Meanwhile, TSMC’s net margin of 55.6% in the second quarter is very high relative to semiconductor peers, indicating strong pricing power, operational efficiency and limited competition.
Micron Has the Edge: Why It’s a Better AI Buy Than TSMC Now
Both Micron and TSMC are well-poised to make the most of the AI boom, fueled by incessant demand for cutting-edge memory and semiconductor chips. Both companies continue to exhibit healthy profitability, expanding margins, and optimistic revenue guidance.
However, TSMC’s debt-to-equity ratio of 15.8% far exceeds Micron’s 5.1%, suggesting greater financial risk and potentially higher downside risk during economic slowdowns.

Additionally, Micron remains more efficient in generating shareholder returns than TSMC. This is because Micron’s return on equity (ROE) of 72.5% exceeds TSMC’s ROE of 40.9%.

Finally, Micron appears more attractively valued than TSMC. Per the price/earnings ratio, MU trades at 11.55 forward earnings compared with TSM’s forward earnings multiple of 26.62.

Therefore, despite both companies remaining leading AI beneficiaries with strong growth prospects, Micron stands out as the better buy due to lower debt, higher returns and a reasonable valuation compared to TSMC. Micron has a Zacks Rank #1 (Strong Buy). You can see the complete list of today’s Zacks Rank #1 stocks here.
