MKS (MKSI)'s quarterly interest expense fell from $59 million to $45 million in a year, and its adjusted EBITDA margin rose to 25.71 TP3T. Even reflecting these structural improvements, the 12-month baseline target price is $306, and the investment rating remains Hold. The current price of $320.76 slightly exceeds the fair forward multiple of 22x.
The Won currency was standardized at 1,427 Won per Dollar (closing price on August 4, 2026). The analysis reference date is August 5, 2026, and the stock price is based on the closing price of the U.S. regular trading session on August 4.
Growth is still in an acceleration phase. MKS reported revenue of $1.078 billion (approx. 1.5383 trillion KRW) in the first quarter of 2026, an increase of 15.21 TP3T year-over-year, and non-GAAP diluted EPS of $2.30, exceeding the upper end of its guidance. The median guidance for the second quarter indicates revenue of $1.2 billion (approx. 1.7124 trillion KRW), a 23.31 TP3T increase year-over-year.
The company's biggest change this year occurred at the bottom of the income statement. By issuing €1 billion in senior bonds (maturating in 2034) and repaying approximately $1.3 billion in term loans early, quarterly interest expenses decreased from $59 million to $45 million. The structure is such that more than $50 million annually is added directly to pre-tax profit.
Nevertheless, the stock price has already largely reflected that improvement. The baseline target price, based on applying an appropriate forward multiple of 22x to a future 12-month (NTM) EPS of $13.90, is $306 (approx. 436,662 KRW), and the scenario-weighted expected return is -5.31 TP3T. The investment rating is Hold, and the confidence level is Medium.

What does MKS (MKSI) sell? — Three business divisions
MKS is a components and subsystems company founded in Andover, Massachusetts in 1961. In May 2025, the company changed its name from MKS Instruments to MKS Inc., and it has 10,200 employees. It does not manufacture semiconductor equipment directly. Instead, it supplies pressure and flow control modules, vacuum meters, RF power supplies, lasers, optical systems, and precision motion stages that go inside the equipment. This means that if you were to open up the etching and deposition equipment of Lam Research or Applied Materials, a significant number of the gas delivery lines and pressure controllers inside would be products of this company.
Revenue is divided across three business units. As of the first quarter of 2026, the Semiconductor division of the Vacuum Solutions (VSD) group generated $466 million (approx. 665 billion KRW), the Electronics & Packaging division $321 million (approx. 458.1 billion KRW), and the Specialty Industries division $291 million (approx. 415.3 billion KRW). Semiconductors account for 431 TP3T, while the remaining 571 TP3T is comprised of Printed Circuit Board (PCB) plating chemicals and industrial lasers. The importance of this composition will be discussed later—while cyclical volatility is lower than that of pure semiconductor equipment stocks, the intensity of benefits from a semiconductor boom is diluted accordingly.
Four terms appearing in this article
- WFE (Wafer Fabrication Equipment) — The market for front-end process equipment that creates circuits on wafers. It is a leading indicator of MKS revenue. SEMI projects that the WFE market will grow by 23.11% to reach $143.9 billion by 2026.
- Adjusted EBITDA — Earnings before interest, taxes, and depreciation, with acquisition-related amortization, restructuring costs, and stock compensation costs rounded back. It is a metric emphasized by companies, but its definition varies from company to company, so it should not be compared directly.
- Net assets excluding intangible assets — The amount remaining after deducting goodwill and intangible assets from equity. For MKS, this value is minus $1.819 billion. This signals that the acquisition consideration is being held as an asset on the balance sheet.
- Preceding P/E — Price-to-earnings ratio divided by the expected EPS for the next 12 months. Since the trailing P/E is distorted for cyclical companies, this article uses the forward standard.
MKS (MKSI) Recent 5-Quarter Earnings Trends and Quality of Earnings
The quickest way to judge this company is to look at five quarters side by side. Revenue has increased for five consecutive quarters, and interest expenses have decreased for five consecutive quarters. The fact that these two lines are moving simultaneously is the entirety of MKS's current story.
| branch | sales | Gross profit margin | Normalized EBITDA margin | Diluted EPS (GAAP) | Interest expense |
|---|---|---|---|---|---|
| Q1 2025 | $936 million | 47.4% | 23.9% | $0.77 | $59 million |
| Q2 2025 | $973 million | 46.6% | 23.0% | $0.92 | $58 million |
| Q3 2025 | $988 million | 46.7% | 23.5% | $1.10 | $56 million |
| Q4 2025 | $1.033 billion | 46.4% | 23.4% | $1.58 | $54 million |
| Q1 2026 | $1.078 billion | 47.0% | 22.5% | $1.18 | $45 million |
There are two points to note regarding the quality of earnings. First, the GAAP EPS of $1.58 for the fourth quarter of 2025 was not a result of strong operations. The corporate tax for that quarter was minus $18 million, meaning it was a tax refund. Pre-tax earnings stood at $89 million, showing little difference from the previous quarter's $84 million. Second, the number of diluted shares for the first quarter of 2026 increased by 4.61 TP3T from 68 million to 71.1 million. Since the number of standard shares remained almost unchanged at 67.4 million, this is the result of the recognition of dilution factors such as conversion rights. This explains why GAAP EPS fell from $1.58 to $1.18, even though pre-tax earnings increased by 151 TP3T from the previous quarter to $102 million.
It is also worth noting that the normalized EBITDA margin dropped slightly from the 231 TP3T range to 22.51 TP3T. While revenue increased by 4.41 TP3T, selling, general, and administrative expenses rose from $185 million to $190 million, and research and development expenses increased from $77 million to $81 million. Since this diverges from the company's emphasized adjusted EBITDA margin of 25.71 TP3T, the key point to watch in these earnings is to see which definition prevailed in the actual Q2 figures.
Cash flow has not yet caught up with profits. With combined operating cash flow of $557 million (approx. 794.8 billion KRW) and free cash flow of $489 million (approx. 697.8 billion KRW) over the past four quarters, the FCF margin relative to revenue stands at 121 TP 3 T. Notably, free cash flow in the first quarter of 2026 was merely $29 million, due to a working capital burden resulting from an increase in accounts receivable of $124 million, rising from $651 million to $775 million. While this is a common phenomenon during periods of rising sales, the fact that inventory also increased from $921 million to $949 million remains a factor to watch.
Debt of $4.292 billion: MKS (MKSI) Financial Health Check
MKS's total borrowings amount to $4.292 billion (approx. 6.1247 trillion KRW) and cash to $569 million (approx. 812 billion KRW), resulting in net borrowings of approximately $3.723 billion (approx. 5.3127 trillion KRW). The debt-to-equity (D/E) ratio against equity of $2.811 billion is 152.71 TP3T. While this is manageable given its market capitalization of $21.665 billion (approx. 30.9 trillion KRW), it is certainly heavy compared to other companies in the semiconductor equipment chain. Applied Materials' D/E is 30.41 TP3T, and Lam Research's is 29.91 TP3T.
The root of the debt lies in the 2022 acquisition of Atotech. As a result, the balance sheet shows $2.565 billion in goodwill and $2.065 billion in other intangible assets, leaving net assets at minus $1.819 billion. Amortization expenses for intangible assets alone cut GAAP earnings by $63 million per quarter. Most of the gap between GAAP EPS of $1.18 and non-GAAP EPS of $2.30 stems from these amortization expenses.
The company began overhauling this structure in 2026. It issued €1 billion worth of €4.25% senior bonds (maturating in 2034), repaid approximately $1.3 billion in existing term loans early through parallel term loan refinancing, and increased the revolving limit to $1 billion. The result is the reduction in interest expense shown in the table. This decrease is from $59 million to $45 million per quarter, and from $236 million to $180 million on an annualized basis. $56 million is transferred to pre-tax profit, and applying the 18% tax rate results in a net profit of approximately $46 million, equivalent to $0.68 per share. The dividend was also raised from $0.22 to $0.25 per share.
However, liquidity indicators require a closer look. The current ratio is 1.11, and the quick ratio is 0.59. Working capital plummeted from $1.583 billion to $254 million due to $1.398 billion in borrowings reclassified as current liabilities during the refinancing process. While this is merely an accounting classification change and the company is far from a liquidity crisis given a revolving capacity of $1 billion, a quick ratio of 0.59 implies that short-term debt cannot be covered without inventory. The detailed conditions are 10-Q filing with the SECYou can check it at.
Q2 figures coming out tonight — guidance and consensus
It is necessary to clarify the timing. MKS will announce its Q2 2026 earnings at 5:00 AM KST on August 6 (after the market close on August 5 in the US East), and the conference call will be held the following day. In other words, this article summarizes the position immediately before the earnings announcement, and the denominator of the valuation below may change depending on the numbers a few hours later.
The company's guidance is revenue of $1.2 billion ± $40 million, non-GAAP EPS of $2.90 ± $0.30, and adjusted EBITDA of $328 million ± $26 million. If the median is accepted, revenue increases by 23.31 TP3T from $973 million in the same period last year, and the adjusted EBITDA margin improves by 1.61 TP3T points to 27.31 TP3T from Q1's 25.71 TP3T. The market consensus is revenue of $1.1917 billion and EPS of $2.94, which is nearly identical to the median guidance. The implications of this alignment are simple—it is difficult to push the stock price up by meeting guidance alone, and Q3 guidance is the real variable.
The precedent to refer to is the first quarter. Revenue was $1.078 billion (consensus $1.05 billion) and non-GAAP EPS was $2.30 (consensus $2.00), exceeding both targets. Adjusted EBITDA for the first quarter was $277 million. Original text of Q1 earnings announcement과 Disclosure of Q2 earnings announcement scheduleIt has been made public.
The stock price trend also reflects this waiting state. After hitting an all-time high of $447.62 (approximately 638,754 KRW) in the last week of June, it fell to $256.16 in the last week of July and returned to $320.76 in the first week of August. The 50-day moving average of $346.64 is below, while the 200-day moving average of $244.67 is above. The one-year growth rate is 223.21 TP3T, and the 52-week low is $88.49 (approximately 126,275 KRW). The short selling balance is 8.681 TP3T of outstanding shares, creating a structure where volatility in both directions could be amplified depending on earnings results.
MKS (MKSI) Valuation: Fair Multiple, DCF, and Competitor Comparison
The trailing P/E figure of 67.2x can be disregarded. Trailing multiples provide no information for cyclic companies where GAAP earnings are suppressed by the amortization of intangible assets. The next 12-month EPS was projected at $13.90 (approximately 19,835 KRW), weighted by the remainder of the period, based on the FY2026 consensus of $11.78 and the FY2027 consensus of $15.45. Based on the current price of $320.76, the forward P/E is 23.1x.
The appropriate multiple was calculated by combining the two axes, rather than using the current multiples directly. First, the 3- to 5-year average forward P/E of MKS itself is approximately 17 times. It has a history of trading lower than pure equipment stocks due to leverage and net assets excluding intangible assets. Second, the median forward P/E of four peers (Applied Materials, Lam Research, Entegris, and Ultraclean) is 29.0 times. Mixing the two values 50-50 yields 23.0 times, and from this, subtracting 1 time to reflect a D/E of 152.71 TP3T and a current ratio of 0.59... 22.0 times...was confirmed as the appropriate multiple. The current 23.1x represents a 4.9% premium compared to this standard.
| event | Market capitalization | Preceding P/E | TTM Sales Growth | EBITDA margin | D/E |
|---|---|---|---|---|---|
| MKS(MKSI) | $21.665 billion | 20.8 times | +15.2% | 23.1% | 152.7% |
| Applied Materials (AMAT) | $433.994 billion | 32.2 times | +11.4% | 32.0% | 30.4% |
| Lam Research (LRCX) | $397.581 billion | 27.6 times | +30.0% | 37.2% | 29.9% |
| Entegris (ENTG) | $22.016 billion | 30.3 times | +5.0% | 27.2% | 92.8% |
| Ultraclean (UCTT) | $3.79 billion | 14.4 times | +24.3% | 6.3% | 108.2% |
What the table indicates is that MKS is different in nature rather than being undervalued. The margin is Lam Research (LRCX)나 Applied Materials (AMAT)It is more than 101 TP3T points lower, and its debt is five times heavier. It is not that the multiple is low; rather, it is a company that ought to have a low multiple. Conversely, compared to Ultraclean, its margins and business stability are overwhelming, so 14 times is excessively low. The judgment is that 22 times falls somewhere in the middle.
A cash flow-based verification yields a much more objective answer. The TTM free cash flow of $489 million is difficult to utilize as is, weighed down by the burden of working capital. From the annualized $1.312 billion—the second-quarter guidance adjusted EBITDA of $328 million—subtracting $180 million in cash interest, $150 million in cash taxes, and $160 million in capital expenditures... Normalized FCF $822 millionIt was used as the reference value.
| DCF assumption | Weakness | basic | stress |
|---|---|---|---|
| Standard FCF | $600 million | $800 million | $950 million |
| 5-year FCF growth rate | 5% | 10% | 13% |
| WACC | 12% | 11% | 10% |
| End-of-life growth rate | 2.0% | 2.75% | 3.0% |
| Calculated value per share | $47 | $144 | $258 |
The DCF fair value range of $145 to $260 is significantly lower than the current price. This gap should neither be trusted nor ignored. Applying a 5-year DCF to an equipment chain company at the beginning of a cycle structurally underestimates its earnings strength at the peak of the cycle. At the same time, because $3.7 billion in net debt is deducted directly from the enterprise value, highly leveraged companies perform at a particular disadvantage under the DCF. In conclusion, The valuation judgment is OvervaluedD — In terms of multiples, it is merely a 4.91 TP3T premium, but in terms of cash flow, the current price is more than double that of the base scenario.
MKS (MKSI) 12-Month Target Price Scenarios and Growth Outlook
We start by disclosing the growth rate assumptions. We weighted historical revenue CAGR of approximately 81 TP3T, analyst consensus-based 181 TP3T, and industry growth rate of 131 TP3T at a 4:4:2 ratio. 13.0%...was applied. The basis for the industry axis is the SEMI forecast. By 2026, semiconductor equipment sales are projected to increase by 23.21 TP3T to $165.9 billion, and looking only at WFE, they are expected to increase by 23.11 TP3T to $143.9 billion, and, SEMI predicts that record levels will continue into 2027.. The driving force is the expansion of DRAM for HBM and advanced logic.
However, only 431 TP3T of MKS's revenue is from semiconductors. The remaining electronics, packaging, and specialty industries sectors are tied to demand for PCB plating chemicals and industrial lasers, so they do not follow the WFE growth rate directly. In addition, there is a structure where tariffs are added to the cost. Therefore, the company's growth rate was projected lower at 131 TP3T rather than the industry growth rate (231 TP3T). Pure player-in in inspection and measurement KLA(KLAC)Compared to that, it is a profile with low upward momentum but high defensive power during the downturn.
| scenario | home | Target price | Won | Compared to the current price | weight |
|---|---|---|---|---|---|
| stress | NTM EPS $15.00 × 26x (Q2 surprise + Q3 guidance upward revision, peer multiple convergence) | $390 | Approximately 556,530 won | +21.6% | 26% |
| basic | NTM EPS $13.90 × 22x (Median guidance achieved, reasonable multiple maintained) | $306 | Approximately 436,662 won | −4.6% | 46% |
| Weakness | NTM EPS $13.00 × 17x (Entering WFE digestion phase, multiple reduced to internal historical average) | $220 | Approximately 313,940 won | −31.4% | 28% |
I would like to explain why I changed the weights from the default 50/25/25 to 46/26/28. Although the multiple premium is merely 4.91 TP3T, meaning it is not in an extremely overvalued zone, the DCF gap is so large that I raised the bearish scenario by 31 TP3T points from the default. Conversely, since the structural EPS leverage resulting from reduced interest expenses operates independently of the cycle, I added 11 TP3T points to the bullish side as well. I also reflected the judgment that the short-term distribution is thick in both directions, given that earnings announcements are just a few hours away.
Wall Street is much more optimistic. The average target price from 13 analysts is $410.77 (approx. 586,169 KRW), with a median of $415, a high of $600 (Cantor Fitzgerald), and a low of $265; the average rating is 1.69, which corresponds to a Buy. Since June, Bank of America has raised its target price from $380 to $500, Key Bank from $360 to $475, and Morgan Stanley from $374 to $442. On the other hand, Goldman Sachs remains with a Sell rating of $200. The difference between my base price of $306 and the consensus average mostly stems from the applied multiples—Wall Street uses 27–29x, close to the peer average, while I use 22x after deducting leverage.
MKS (MKSI) Risks and Bearish Triggers
For risks, list the occurrence path and verification indicators together.
- Leverage and Interest Rates → Earnings SensitivityA significant portion of the $3.723 billion in net borrowings consists of variable-rate term loans. If interest rates rise by 11 to 3 points, pre-tax earnings are cut by tens of millions of dollars. A key indicator is the reversal of quarterly interest expenses—whether they continue to fall below $45 million or rise again is the signal.
- High beta + High short selling → Volatility amplification: Beta 2.0, short selling volume is 8.681 TP3T of outstanding shares. The case where the stock price fell from $334 to $256 in a single week during the last week of July illustrates this structure. The confirming indicator is the monthly short selling volume trend (increased from 4.58 million shares in the previous month to 5.16 million shares).
- Non-semiconductor revenue 571 TP 3 T → Growth dilutionIf the electronics, packaging, and specialty industries stagnate regardless of the AI cycle, growth in the semiconductor sector will be offset. The confirming indicator is the gap in revenue growth rates by segment. In the first quarter, semiconductors drove growth by $466 million.
- Working capital → Cash flow delayDue to a $124 million increase in accounts receivable, Q1 FCF stood at only $29 million. Inventory also increased. The key indicators are inventory turnover days and the quarterly FCF conversion rate.
To clarify the bearish triggers: ① If Q2 non-GAAP EPS falls below the lower end of the guidance at $2.60, or ② if Q3 revenue guidance fails to exceed $1.2 billion, the basis for the market premium disappears. ③ If the adjusted EBITDA margin fails to reach 271 TP 3T, the narrative of margin improvement itself begins to waver. If two or more of these conditions overlap, the author's bearish scenario of $220 enters the valid zone. The triggers in the opposite direction are Q3 revenue guidance exceeding $1.3 billion and an adjusted EBITDA margin breaking through 281 TP 3T. The risk associated with the upper-end multiple of the cycle is Teradyne (TER) AnalysisIt is the same as the structure discussed in.
Stories outside the data
While examining MKS, what caught my eye most was not revenue or margins, but the speed at which interest expenses were declining. For five consecutive quarters, the figures were $59 million → $58 million → $56 million → $54 million → $45 million. In semiconductor component stocks, this kind of "profit growth driven by financial cost reduction" operates independently of the cycle narrative. That is why I keep this stock in the "deleveraging recovery stocks" category rather than the AI growth stock basket. Placing a stock in a different category alters expectations—it no longer demands multiples from the cycle's peak.
At the same time, the fact that net assets are minus $1.819 billion after deducting intangible assets continues to weigh on me. This implies that the afterimage of the Atotech acquisition remains on the balance sheet, and it is also the reason why the DCF fails to track even half of the stock price. Most of the gap between the consensus average of $410 and my base scenario of $306 stems from this point. The market looks at the earnings at the peak of the cycle first, while I look at the balance sheet first. It will take two or three quarters after tonight to determine which is correct. Furthermore, the very fact that earnings are just a few hours away narrows the validity of this post—so this time, I believe the range of the three scenarios ($220–$390) is a more honest answer than a single target price.
MKS (MKSI) Investment Opinion: Conclusion
Hold, Medium confidence, 12-month baseline target price of $306 (approx. 436,662 KRW). There are four signals that led to this conclusion. First, the forward P/E of 23.1x represents a premium of 4.91 TP3T over the fair multiple of 22.0x, indicating that it is not extremely overvalued. Second, the scenario-weighted expected return of -5.31 TP3T falls within the Hold range (-81 TP3T to +121 TP3T). Third, fundamentals are improving—revenue has increased for five consecutive quarters, interest expenses have decreased for five consecutive quarters, and dividends have been raised. Fourth, the fact that the DCF fair value of $145–$260 is significantly below the current price limits the upside. At the point where the valuation judgment of Overvalued conflicts with the band judgment of Hold, I chose Hold based on the fact that the premium range is limited to 4.91 TP3T. However, it should be noted that this is the lower end of the Hold range.
The reason this diverges from the Wall Street consensus of a Buy (average target price of $410.77) lies solely in the applied multiple. I did not simply use the peer median of 29x, citing a D/E ratio of 152.71 TP3T, a current ratio of 0.59, and negative net assets excluding intangible assets. There is also a clear path for this judgment to go wrong—if deleveraging continues and the debt ratio falls below 1001 TP3T, my 1x reduction itself loses its basis, and the appropriate multiple rises to 23–25x. At that point, the target price shifts into the $320–$350 range. Ultimately, this is a stock that requires tracking the balance sheet rather than earnings. It serves as an example within the same equipment chain that carries valuation burdens. McCom (MTSI) AnalysisIt is also worth referring to.
Frequently Asked Questions
What is the 12-month target price for MKS (MKSI)?
The base scenario is $306 (approximately 436,662 KRW). This value is calculated by applying an appropriate forward multiple of 22.0x to a 12-month EPS of $13.90. The bullish scenario is $390, the bearish scenario is $220, and the weighted expected return is -5.31 TP3T. For reference, the average target price from 13 analysts is $410.77, with a high of $600 and a low of $265.
Is total borrowings of $4.292 billion a dangerous level?
Although the immediate risk of default is low, the multiples warrant a discount. Net borrowings of $3.723 billion represent approximately four times TTM EBITDA of $941 million, with a D/E ratio of 152.71 TP3T. This is five times heavier than Applied Materials (30.41 TP3T) or Lam Research (29.91 TP3T). However, quarterly interest expenses decreased from $59 million to $45 million due to the issuance of €1 billion in senior debt and the early repayment of a $1.3 billion term loan, and a revolving credit limit of $1 billion has been secured. The direction is toward improvement.
What is the biggest bearish trigger that can drive stock prices down?
This is the case where third-quarter revenue guidance fails to exceed $1.2 billion. Since the median of the second-quarter guidance is nearly identical to the market consensus, meeting the second-quarter target alone is not enough to justify the premium. Furthermore, if the adjusted EBITDA margin falls below 271 TP3T, the narrative of margin improvement is shaken. Given the structure with a beta of 2.0 and a short selling volume of 8.681 TP3T of outstanding shares, downside reactions are prone to amplification.
