MKS Instruments (MKSI): Evaluating Valuation Following Strong Revenue Growth and Renewed Market Demand

Recent commentary from a large fund has brought MKS (MKSI) into focus, as the company reported both sequential and year-over-year revenue growth in its latest quarter. This upward trend suggests strengthening demand across its primary end markets.

See our latest analysis for MKS.

MKS’s share price has surged over 35% in the past three months, as renewed demand in its core semiconductor markets and stronger sentiment lifted the stock. Its one-year total shareholder return of 24% points to building momentum, with recent news only adding fuel.

If MKS’s run has you thinking about what else is gaining traction, now is the perfect moment to broaden your search and discover fast growing stocks with high insider ownership

With shares climbing rapidly and demand rebounding in key segments, the key question is whether MKS still offers value for new investors or if the current price already reflects expectations for future growth.

Most Popular Narrative: 17.6% Undervalued

According to the most widely tracked narrative, MKS’s fair value is set at $174.85, which is well above its last close price of $144 and signals significant perceived upside. This difference, based on fresh business catalysts and raised expectations, creates the context for a bullish take by analysts.

The company's deepening integration of advanced materials and chemistry equipment (including Atotech) positions MKS as a unique provider of both tools and consumables required for the shift to multilayer, high-density AI-related applications. This is enabling cross-selling and leading to improvements in revenue growth as well as structural enhancements in gross and operating margins.

Another View: What Do Valuation Ratios Say?

Looking through the lens of the standard price-to-earnings ratio, MKS appears more expensive than its industry and peer averages. Its current P/E of 34.7x stands above the US semiconductor industry average of 33.7x and its peers at 33.5x, and exceeds the market's fair ratio. This suggests investors are currently paying a premium, which could signal heightened risk if expectations falter. However, the question remains whether these elevated multiples reflect real opportunity or optimism running ahead of reality.
