Fresh analyst upgrades and reaffirmed Buy ratings have pushed MKS (MKSI) back onto investors’ radar, as the semiconductor technology supplier sees confidence in its outlook rise alongside expectations for continued earnings momentum.

Even after a sharp pullback last week, with a 7 day share price return of negative 11.42 percent, MKS is still up meaningfully this year thanks to a 40.26 percent year to date share price return and a 43.96 percent 1 year total shareholder return. This suggests that recent weakness appears more like cooling momentum than a broken story.

If this kind of cyclical semiconductor upswing has you rethinking your watchlist, it might be worth exploring other high growth tech and AI names through high growth tech and AI stocks to spot the next wave of potential leaders.

With earnings accelerating, a Strong Buy analyst consensus, and shares still trading below price targets, is MKS quietly undervalued, or are investors already paying up for all of its future growth potential?

Most Popular Narrative: 15% Undervalued

With MKS last closing at $148.70 against a narrative fair value of $174.85, the story being told hinges on robust, compounding earnings power.

The operational pivot toward a more stable, services driven revenue mix (including higher margin annuity like service streams from the installed base) is increasing business resilience, supporting net margin expansion and reducing earnings volatility.

Curious what kind of revenue mix shift justifies that upside, and what profit multiple it assumes years from now? The narrative leans on sustained growth, rising margins, and a future earnings valuation usually reserved for elite chip names. Want to see the full chain of assumptions that underpins that fair value jump?

Result: Fair Value of $174.85 (UNDERVALUED)

However, high leverage and exposure to cyclical wafer equipment demand could quickly pressure margins and sentiment if the upcycle stumbles.

Another Angle on Value

There is a catch. Our SWS DCF model puts MKS's fair value closer to $87.22 per share, which would make the current $148.70 price look expensive, not cheap. Are investors already pricing in a best case earnings ramp that the cash flows do not yet support?
