MKS Instruments IncEPS up 86% and revenue up 28%, but margin headwinds noted

MKS Inc. reported second-quarter revenue up 28% year-over-year to $1.25 billion and non-GAAP earnings per share of $3.30, an 86% increase, but management warned that its equipment sales strategy is temporarily pressuring gross margin. Semiconductor revenue climbed 28% to $554 million, Electronics and Packaging jumped 44% to $381 million, and Specialty Industrial rose 14% to $313 million, driven by AI server buildouts and NAND upgrade cycles. CFO Ram Mayampurath said equipment carries lower margins than proprietary chemistry and facility ramp costs are being absorbed, with third-quarter gross margin guided near 47%, roughly flat despite further revenue growth. The company is doubling capacity at its Guangzhou chemistry equipment factory, expected online in the third quarter of 2027, and its Malaysia supercenter is sized for industry-wide wafer fab equipment spending of $200 billion to $250 billion. Hedge fund ownership increased from 52 to 71 funds, while short interest stands at 9.67% of the float.
