What is MKS seeing with NAND tool upgrades and other memory investments, and what is the potential effect on consumer products given the memory crunch?

Customers are investing heavily in DRAM for AI, causing a memory crunch. NAND is also becoming a bottleneck, with new factory announcements extending ramps. MKS is well-positioned for NAND upgrades due to its RF power for vertical channel etching. While consumer products (PCs/smartphones) might see low single-digit decreases, AI demand is expected to more than offset this. “NAND is something that's going to be kind of icing on the cake as that happens throughout the year and the next couple of years. ... if we have a little decrease in PCs and smartphones, I think it's going to be more than made up with AI.”

What is MKS's opinion on WFE growth this year, given strong outlooks from customers and peers, and how will it flow through to MKS's semiconductor sales?

Management expects WFE to be a large grower, with some customers projecting 15-20% YoY growth. MKS has a track record of outperforming WFE in upturns because its products are already designed-in and customers build inventory. The ramp has started, and MKS is preparing its supply chain to meet demand. “A couple of our edge customers are talking about 20% year-over-year WFE growth... So you put it all together, WFE will be a large grower. And I think more importantly, I think everybody is kind of assuming it's more than just a 1-year thing.”

How can the revenue opportunity from AI-driven board complexity be quantified, and how much can it offset consumer electronics weakness?

AI boards require significantly more layers (15-20 for HDI, 30-40 for multilayer) compared to smartphones (10-12 layers). AI chemistry revenue grew from 5% of total chemistry revenue in 2024 to 10% in 2025. This growth is expected to continue and more than compensate for any slight decrease in the PC and smartphone markets. “the HDI type of boards for AI are in that 15% to 20% already. And in addition, AI also needs multilayer boards, which are in the 30 to 40 layers. ... AI chemistry is really -- we are expecting that to continue to grow.”

Q&A highlights

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

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.

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.

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.

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.

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.
