The semiconductor sector is the hottest ticket in town for investors, with skyrocketing chip demand captivating the market.

Enter two titans: Taiwan Semiconductor Manufacturing Company (TSMC) and ASML Holdings NV. Both have just unveiled impressive earnings reports, but which one is the smarter buy?

Earnings Showdown!

In the second quarter of 2025, TSMC reported an impressive 38.6% year-on-year revenue surge, reaching NT$933.8 billion. Their net profit increased by a staggering 60.7% to NT$398.27 billion, fueled by soaring demand in artificial intelligence (AI) and high-performance computing (HPC). Notably, their cutting-edge 5nm and 3nm chips accounted for 36% and 24% of total wafer revenue, respectively.

Meanwhile, ASML also posted strong numbers—showing a 23.2% revenue increase to €7.7 billion, with a net profit of €2.3 billion, up 45.1% year-on-year. Their success was driven by a spike in demand for dynamic random-access memory chips and their innovative extreme ultraviolet (EUV) lithography machines. A notable boost in their installed base management sales, hitting €2.1 billion, highlighted the strong upgrade business.

Strategic Moves for Global Dominance

On July 17, 2025, TSMC revealed bold plans for expansion, which includes 11 new wafer manufacturing fabs and four advanced packaging facilities in Taiwan alone. Additionally, they're strategizing globally with a GIGAFAB set for Arizona and specialty fabs in Japan. This ambitious growth aims to solidify client loyalty and mitigate geopolitical risks, spurred by uncertainties like the US-China trade tensions.

ASML, on the other hand, marked a milestone by shipping its first EXE:5200B system—an innovative lithography machine that offers better overlay performance, demonstrating their commitment to leading-edge technology and higher productivity.

Positive Projections Ahead

Looking forward, TSMC anticipates a phenomenal 30% revenue growth in 2025, underpinned by burgeoning AI demand. However, they remain cautious, noting potential challenges from tariff policies impacting sensitive market segments.

ASML is equally optimistic, projecting a 15% growth in net sales alongside a solid 52% gross margin for fiscal 2025, closely tied to the AI industry's expansion. That said, they acknowledge the lurking risks posed by global political tensions.

Investors, Take Note!

Both companies play critical roles in the chipmaking ecosystem, making them appealing options for investment. However, savvy investors should carefully weigh growth potential against inherent risks.

A common misconception in today’s market is that lowered AI costs will result in reduced revenue for tech firms. But a leading tech CEO offers a compelling counterpoint, suggesting that lower AI costs might actually trigger increased tech spending.
