What Do These Terms Mean?
- EPS (Earnings Per Share):
- Quarterly profit divided by the total share count — how much of the profit works out to a single share.
- YoY (Year over Year):
- Change versus the same quarter a year ago — this is how you compare without seasonal distortion (e.g. the holiday shopping season).
- Sales:
- All revenue for the quarter, before any costs are deducted — the top line of the income statement.
- Net Margin:
- What percentage of sales is left over as profit in the end. Negative means the company is posting a loss.
- OCF (Operating Cash Flow):
- The cash that actually flows into the till from the core business during the quarter — harder to dress up than book profit.
- FCF (Free Cash Flow):
- Operating cash flow minus capital expenditures — the money that's genuinely free to use, say for paying down debt, buybacks, or dividends.

Analysts & Price Target
Combined picture of the price targets and recommendations of every analyst covering the stock. Price targets are expectations for the next 12 months, not promises — and they often follow the price rather than predict it.

Valuation
What is priced in?
Instead of guessing what the stock is worth, we turn the question around: what free cash flow growth has to happen for today’s market value to add up? The assumptions behind it can be moved.
Today’s market value implies roughly 16.7% growth in free cash flow per year over ten years (assumptions: discount rate 10.0%, terminal growth 2.5%).
| Free cash flow (last twelve months) | $454.0M |
|---|---|
| Market cap | $17.54B |
| Free cash flow in year ten | $2.12B |
| Terminal value as a share of market value | 63.7% |
For comparison: over the past five years free cash flow grew by 3.0% per year.
It shows which assumption is built into today’s price, not whether that assumption will hold. Every assumption can be changed with the sliders; the figures move with them.
A simplified model calculation — not a forecast and not a recommendation.
AI classification
AI Rating
MKS Inc. (vormals MKS Instruments) verkauft keine KI-Produkte; das Kerngeschäft — Präzisionsinstrumente, Subsysteme und Prozesschemie für die Halbleiterfertigung — profitiert nur als Endmarkt-Zulieferer vom KI-Chip-Boom (die 10-K-Berichte nennen „AI-related demand“ als Nachfragetreiber im Halbleiter- und Elektronikgeschäft, das laut Kriterienkatalog allein noch kein „verkauft“ begründet). Operativ belegt der Geschäftsbericht (10-K) 2025 einen frühen, begrenzten internen KI-Einsatz („We are in the early stages of integrating AI into our business and operational processes“) — damit greift Rang 3 „nutzt“. Ein konkretes KI-Geschäftsrisiko fürs eigene Modell (Rang 2 „bedroht“) wird nicht als existenziell dargestellt, eine KI-Umsatzquelle (Rang 1 „verkauft“) fehlt.

Earnings calls
What the Earnings Calls Reveal
Across ten calls from fiscal 2023-Q4 through 2026-Q1, the MKS management team led by CEO John Lee shows an unusually reliable pattern: quarterly guidance was met or beaten in all nine verifiable cases, mostly at the upper end of the range. The only reversal - the second-half 2024 recovery expectation was temporarily withdrawn on the 2024-Q2 call - was explained openly and ultimately delivered anyway. Deleveraging, tariff mitigation and the CFO succession all played out as announced; still open are the gross margin target of above 47 percent and the long-term leverage target.
Guidance met or beaten nine quarters in a row
From 2024-Q1 through 2026-Q1, revenue landed at least at the midpoint of the company's own guidance in every single quarter, usually at or above the high end: 2024-Q1 868 million dollars (midpoint 840), 2025-Q2 973 million (above the 965 high end), 2026-Q1 1.08 billion (high end of the range). Earnings per share exceeded the high end in 2024-Q1, 2024-Q2, 2024-Q3, 2025-Q1 and 2026-Q1. Management deliberately guides only one quarter out and sets the bar visibly conservative - a pattern that stayed stable over the entire period.
The one 2024 reversal: openly explained and delivered after all
On the 2023-Q4 and 2024-Q1 calls, management pointed to second-half 2024 revenue slightly above the first half. On the 2024-Q2 call this was cut back to 'roughly in line' - with a clear reason: the industry recovery was pushing out, they were 'bouncing along the bottom a little longer than we thought'. On the 2024-Q3 call the expectation was raised again to low-to-mid single digit growth, and that is exactly what happened: the second half came in about 4 percent above the first. A zigzag in expectations, but no broken promise - and communicated transparently throughout.
Deleveraging as announced, but target stated inconsistently
The pledge repeated since 2023-Q4 to put excess free cash flow into debt reduction was consistently honored: 426 million dollars of voluntary prepayments in 2024, 400 million in 2025, over 1 billion in total since February 2024; net leverage fell from 4.7x (2023-Q4) to 3.5x (2026-Q1). The only wrinkle is the target itself: on the 2024-Q4 call CFO Mayampurath named '2x net' as the goal, while on the 2025-Q3 call, asked about '2x by 2027', he confirmed '2.5' as the net target - without explaining the shift. No date for the target was ever promised.
Tariffs: estimate slightly missed, mitigation delivered
On the 2025-Q1 call management sized the tariff hit to gross margin at 'up to 100 basis points'; the actual figure in 2025-Q2 was 115 basis points - a miss the team acknowledged itself on the following call. After that, the announced reduction ran on schedule: 80 basis points in 2025-Q3, about 50 from 2025-Q4 with dollar-for-dollar offset, 30 to 40 in 2026-Q1. The commitment given on the 2025-Q1 call to a long-term gross margin above 47 percent is not yet fulfilled: 2025 ended at 46.7 percent and 2026-Q1 reached exactly 47.0 percent - the 'plus' is still pending, but the target was reaffirmed on every call.
Consistent non-answers rather than evasion
Questions about full-year WFE forecasts and the timing of the NAND recovery were as a rule not answered with numbers by CEO Lee across all calls ('If I could do that, I don't have to do this job', 2025-Q1) - a stated policy, not situational dodging, and it was never broken. On the AI revenue share, disclosure actually improved measurably: in 2024-Q4 a breakdown was still called 'difficult', but from 2025-Q3 management gave concrete figures (AI share of chemistry revenue from 5 percent in 2024 to 10 percent in 2025, heading toward 15 percent in 2026-Q1). We found no repeated evasion of the same concrete question.
Management promises
- 2023-Q4 — Reach 55 million dollars of Atotech cost synergies by the end of 2024-Q2. Reported as exceeded already on the 2024-Q1 call - one quarter earlier than promised and at the early end of the original 18-to-36-month window. kept
- 2023-Q4 — Name a successor for retiring CFO Seth Bagshaw and keep the market updated. Status update on every interim call; on the 2024-Q3 call Ram Mayampurath was introduced as the new CFO (start October 2024). kept
- 2024-Q1 — Second-half 2024 revenue slightly above the first half. Temporarily cut to 'in line' on the 2024-Q2 call, raised again on the 2024-Q3 call; H2 actually came in about 4 percent above H1 - the original statement ended up true. kept
- 2024-Q4 — Keep reducing net debt with excess free cash flow, target 2x net. The paydown is demonstrably on track (4.3x at end of 2024 to 3.5x in 2026-Q1, over 1 billion dollars repaid since February 2024); however, the target itself was stated as 2.5x instead of 2x on the 2025-Q3 call, and no date was ever promised. open
- 2025-Q1 — Long-term gross margin above 47 percent despite tariff costs. 2025 ended at 46.7 percent (tariffs, equipment mix), 2026-Q1 reached 47.0 percent again and the Q2 guide holds that level; the 'plus' is still outstanding, and the target is reaffirmed on every call. open
- 2025-Q3 — Offset tariff costs dollar for dollar from 2025-Q4, residual gross margin impact around 50 basis points. Confirmed as largely achieved on the 2025-Q4 call (residual around 50 basis points), down to 30 to 40 basis points in 2026-Q1 - reduced as announced. kept
