MKS Inc. is investing $25 million to expand its Atotech equipment manufacturing site in Guangzhou, China, adding approximately 323,000 square feet of manufacturing and operations space. The expansion is expected to double the site's production capacity when completed in the fourth quarter of 2027. The investment aims to support sustained growth in AI-related markets, particularly semiconductor, advanced packaging and advanced PCB applications. The facility will enhance capabilities across production, assembly, logistics and testing whilst continuing to support research and development activities. The expanded site will incorporate a photovoltaic power system to supply daytime electricity demand. Once fully operational, the facility is expected to generate significant additional annual output, strengthening MKS' position in high-growth electronics markets across Asia.

MKS Inc. has raised its outlook following first-quarter results that met analyst expectations, with statutory earnings of $1.18 per share and revenues of $1.1 billion exceeding predictions by 3.1%. The semiconductor equipment maker's shares rose 7.4% to $313. Following the results, analysts significantly upgraded their forecasts. The consensus revenue estimate for 2026 increased to $4.79 billion, representing 18% growth, up from a previous forecast of $4.48 billion. Earnings per share estimates jumped 67% to $8.07, compared to the earlier projection of $6.43. Analysts also raised their price target 18% to $357 per share. The company is expected to achieve 24% annualised growth through 2026, substantially faster than its historical 7.3% rate and broadly in line with industry peers.

MKS reported first-quarter 2026 results exceeding guidance, with revenue, gross margin and earnings per share all at or above the high end of projections. The company expects momentum to continue into the second quarter, driven by strong bookings across end markets. Chief executive John Lee highlighted MKS's position to capitalise on AI-driven semiconductor capital expenditure plans, which are accelerating technology transitions requiring more complex vertical device structures. In electronics and packaging, the company's chemistry and equipment capabilities are benefiting from AI-driven increases in advanced circuit board complexity. MKS is preparing to open a new manufacturing facility in Malaysia in June to support demand growth. The company attributed its strong performance to recent design wins and continued research and development investment during the industry downturn.
