MKS Inc.

MKS reported Q2 revenue of $1.25 billion, up 16% sequentially and 28% year over year. Semiconductor revenue was $554 million, up 19% sequentially and 28% year over year; Electronics and Packaging revenue was $381 million, up 19% sequentially and 44% year over year; Specialty Industrial revenue was $313 million, up 8% sequentially and 14% year over year. Gross margin was 47.6%, operating income was approximately $320 million with a 25.6% operating margin, adjusted EBITDA was $358 million with a 28.6% margin, and EPS was $3.30 per diluted share, up 86% year over year. Cash flow was strong, with free cash flow of $188 million and over $1.6 billion of liquidity. For Q3, MKS guided to revenue of $1.35 billion plus or minus $40 million, gross margin of 47% plus or minus 100 basis points, operating income of $355 million, adjusted EBITDA of $395 million plus or minus $28 million, and EPS of $3.58 plus or minus $0.31. End-market Q3 guide was Semiconductor at $630 million plus or minus $15 million, Electronics and Packaging at $385 million plus or minus $15 million, and Specialty Industrial at $335 million plus or minus $10 million. CapEx is still expected to be 4% to 5% of revenue for the year, and the full-year tax rate is expected at the lower end of the 18% to 20% range.

John Lee framed the quarter as evidence that MKS is gaining momentum across its portfolio and benefiting from AI-driven investment in semiconductors and advanced packaging. He emphasized that the company is seeing strong demand, healthy backlog, and continued design wins, while also investing in capacity, working capital, and new facilities in Malaysia and Guangzhou to support demand through 2027 and beyond. His tone was confident and expansive, repeatedly describing MKS as a foundational enabler of advanced electronics and saying the company is prepared for an accelerating environment.

Ram Mayampurath highlighted the financial strength of the quarter, including 47.6% gross margin, about $320 million of operating income, 28.6% adjusted EBITDA margin, and $232 million of net earnings, or $3.30 per diluted share. He said free cash flow was $188 million, liquidity was over $1.6 billion, and leverage ended Q2 at 3x based on trailing 12-month adjusted EBITDA of $1.1 billion, down one full turn year over year. He also noted a $100 million term loan prepayment earlier in the week, a $0.25 dividend, and said CapEx and working capital will rise through the rest of the year as the company prioritizes organic growth and deleveraging.

Analysts focused on NAND upgrades versus future greenfield projects, the visibility into 2027, E&P chemistry growth, Malaysia and Guangzhou capacity, gross margin pressure, and deleveraging. Management said NAND upgrade activity should continue, greenfield NAND fabs are expected to come toward the end of 2027 and beginning of 2028, and RF power is the biggest cost component of the upgrade opportunity. On capacity, MKS said Malaysia has begun first shipments, Guangzhou’s second factory is planned for Q3 2027, and the company believes its expanded footprint can support a WFE environment of $200 billion to $250 billion. On margins, management said Q2 included about 100 basis points of discrete benefit from tariff and duty refunds, and that ramp investments and unfavorable mix from equipment growth are temporary headwinds.
