    Executive summary

    MKS Q4 FY25 — Strong Execution and Strengthening Demand

    MKS delivered impressive execution in Q4 FY25, driven by strengthening demand across its semiconductor and Electronics & Packaging markets, particularly in AI-related applications. The company achieved strong financial results, outperforming WFE growth and making significant progress on deleveraging with over $1 billion in debt paid down since early 2024. While Q1 gross margins are expected to be seasonally lower due to Lunar New Year and product mix, MKS is strategically investing in capacity and optimizing its capital structure to capitalize on a robust demand environment.

    Semiconductor
    Q4 revenue driven by strengthening demand in DRAM and logic/foundry applications, led by plasma and reactive gases products. Full year 2025 revenue was $1.7 billion, up 13% year-over-year, driven by plasma and reactive gases and racking products. Service business was a steady growth contributor. Q1 FY26 revenue expected to be $450 million, up sequentially.

    Q4 sequential improvement reflected higher flexible PCB drilling and chemistry equipment sales. Strong year-over-year comparison reflected healthy underlying growth across chemistry, flexible drilling equipment, and chemistry equipment. Full year 2025 revenue was $1.1 billion, up 20% year-over-year. Q1 FY26 revenue expected to be $305 million, up slightly sequentially and up low 20% year-over-year.

    Q4 sequential increase largely due to improvement in research and defense markets and certain industrial applications, partially offset by a decline in automotive. Full year 2025 revenue was $1.1 billion, down 4% year-over-year, primarily due to softness in industrial markets including automotive. Q1 FY26 revenue expected to be $285 million, down low to mid-single digits sequentially due to Lunar New Year, but up mid-single digits year-over-year.

    Q&A highlights

    8

    How much of the Q1 gross margin guide is due to chemistry equipment mix, and does the lower Q1 suggest an upward inflection in Q2 from higher chemistry sales volume?

    The lower Q1 gross margin is primarily due to seasonality from lower chemistry sales driven by Lunar New Year. Management expects the mix to improve in Q2 and further in Q3, making Q1 the low point for the year.

    “It is due to the seasonality from lower chemistry driven by Lunar New Year and we expect the mix to improve in Q2 and further in Q3. So mix is the main reason for the 4% to 6% plus or minus 100 basis points guide.”

    Detailed Narrative

    01

    Strong Full Year 2025 Performance and Market Position

    MKS delivered impressive execution in 2025, achieving 10% sales growth, 20% EPS growth, and over 20% free cash flow growth. The company maintained strong gross margins despite trade policy dynamics and proactively reduced its leverage. MKS's semiconductor business outperformed estimated WFE growth for the full year 2025, consistent with its track record in improving demand environments, supported by a broad portfolio of designed-in products foundational to advanced electronics.

    02

    Strengthening Demand Outlook and AI Tailwinds

    The demand outlook across MKS's semiconductor and Electronics & Packaging markets is strengthening, driven by ambitious CapEx plans from large chip manufacturers. AI is a significant driver, increasing packaging complexity and demand for more complex PCBs with rapidly increasing numbers of layers (e.g., 15-20 layers for AI HDI, 30-40 for AI multilayer, compared to 10-12 for smartphones). AI-related chemistry sales grew from 5% of total chemistry revenue in 2024 to 10% in 2025, offsetting some softness in the PC and smartphone markets.

    03

    Strategic Capacity Expansion and Supply Chain Readiness

    MKS is ramping its new supercenter factory in Malaysia in the second half of 2026, which will provide added capacity and resiliency for future WFE needs. The company's current factories are ready to meet demand for the next one to two years, with 30% surge capacity above a $125 billion WFE run rate. While supply chain constraints are a potential challenge during a ramp, MKS is confident in its ability to manage these issues and deliver to customers on time, as it has in previous cycles.

    04

    Deleveraging and Capital Structure Optimization

    MKS made a $100 million voluntary prepayment on its term loan in February 2026, contributing to over $1 billion in debt reduction since February 2024. The company also repriced its term loan facility, reducing credit spreads by 25 basis points on its U.S. term loan and 50 basis points on its Euro loan. Furthermore, a successful EUR 1 billion bond offering diversified the capital structure, reduced interest rates, replaced secured debt with unsecured debt, and extended maturities, resulting in an estimated $27 million annual reduction in interest expenses.

    05

    Electronics & Packaging Growth Drivers

    The Electronics & Packaging business saw strong growth in 2025, with chemistry sales increasing 11% year-over-year (excluding FX and palladium pass-through) and overall segment revenue up 20%. This growth was driven by capacity additions from chemistry equipment and flexible PCB drilling equipment. MKS's model indicates that every $100 million in installed equipment translates to $20 million to $40 million in annual chemistry sales, with a conversion timeline of 18 to 24 months, suggesting future chemistry revenue growth from recent equipment shipments.
