MKS INC MKSI

MKS is benefiting from increasing device complexity in advanced packaging, particularly for high-performance computing and AI applications. The company's chemistry solutions and equipment are critical for optimizing interconnects, with chemistry revenue growth reflecting leadership in advanced packaging technologies. Equipment sales are a leading indicator for future chemistry consumable revenue, with a 6-12 month qualification period before production. AI's contribution to chemistry revenue has doubled over the last year, now representing about 10% of the total PCB business, and mid-teen percentages of the E&P business when including equipment.

The semiconductor segment showed solid year-over-year growth, driven by strength in deposition, etching, and dissolved gas systems for advanced memory and logic. While lower NAND upgrade activity led to a sequential decline in Q3, MKS maintains a strong position in power delivery for these applications and expects double-digit year-over-year growth for FY25. Management anticipates benefiting from an expected high single-digit increase in WFE in 2026, potentially outgrowing the market due to its broad product portfolio.

MKS continues to prioritize debt reduction, having made $400 million in voluntary principal prepayments on its term loan in 2025, following $426 million in 2024. The company exited Q3 with a net leverage ratio of 3.9x and strong free cash flow generation of $147 million. MKS's capital allocation strategy remains focused on investing in organic growth opportunities while reducing leverage, with a long-term net leverage target of 2.5x.

Q3 GAAP gross margin was 46.6%, impacted by a higher mix of chemistry equipment sales and tariffs. While mitigation actions are expected to offset tariff costs dollar-for-dollar, a 50 basis point dilution from tariffs is anticipated to continue in Q4 and beyond due to zero-margin pass-through. Despite these pressures, management remains confident in achieving its long-term gross margin objective of 47% plus through efficiency and operational excellence programs.

The industry's shift towards thicker, multi-layered boards (from 20 to 40 layers currently, with 80-100 layers in development) for AI applications presents significant opportunities for MKS. The company's equipment is uniquely qualified for processing these complex boards, leading to high attach rates for its proprietary chemistry solutions. This trend is expected to extend to PCs and mobile devices as AI inferencing becomes more widespread, creating a huge potential growth driver for the company.

MKS observes significant geographic movement in the industry, with customers onshoring chip and packaging fabs to the US, Japan, and Europe, and a 'China Plus One' trend driving capacity to Southeast Asia. While advanced electronics packaging sales to China remain a substantial part of the business, the semiconductor equipment direct to China market is largely out of MKS's numbers due to restrictions. The company is building factories in Southeast Asia to meet this shifting demand.
