Deep Intelligence Across Industries

MKS Inc. is one of the broadest subsystem suppliers to the semiconductor equipment industry, and it pairs that franchise with lasers, photonics and specialty chemistry. Founded in 1961 around pressure measurement, it now supplies the gas delivery, pressure control, RF power, reactive gas, laser and optical subsystems inside wafer fabrication tools, plus the plating chemistry and equipment used to build printed circuit boards, package substrates and wafer-level packages. The company says it addresses more than 85% of the wafer fabrication equipment ecosystem. Three deals built today's company: Newport in 2016, ESI in 2019 and Atotech in 2022. Atotech added a recurring chemistry stream but also heavy debt and a USD 1.9 billion impairment in 2023. MKS is now deleveraging into an AI-driven upturn: revenue grew 28% in Q2 2026, net leverage fell to 3.0x, and management is preparing for an Investor Day in December 2026. ### The company's own description The FY2025 10-K states: "We enable technologies that transform our world. We deliver foundational technology solutions to leading edge semiconductor manufacturing, electronics and packaging, and specialty industrial applications." It adds that MKS applies "broad science and engineering capabilities to create instruments, subsystems, systems, process control solutions and specialty chemicals technology that improve process performance, optimize productivity and enable unique innovations for many of the world's leading technology and industrial companies." The company frames its offer through two product strategies and an extension of the second: **Surround the Wafer®:** covers products, design and development services, system-level integration, training, calibration, service and repair for semiconductor customers. It updates the earlier Surround the Chamber® label because the photonics business for lithography, metrology and inspection extends beyond the vacuum chamber. **Surround the Workpiece®:** covers design, integration, system selection and maintenance in laser-based guidance and control of manufacturing processes. **Optimize the Interconnect®:** is the extension created with Atotech. It combines laser drilling with chemistry for printed circuit board (PCB) and package substrate manufacturing. ### Independent characterization MKS is best understood as three linked businesses that sit one level below the equipment makers. The Vacuum Solutions Division sells subsystems mostly to semiconductor capital equipment manufacturers, so it behaves like a wafer fabrication equipment (WFE) derivative with a growing service tail. The Materials Solutions Division sells proprietary plating chemistry that is consumed in production, along with plating equipment. Its revenue depends more on production volumes and layer counts than on capital spending, and the installed equipment tends to pull through chemistry sales. The Photonics Solutions Division is a mix of lasers, optics, motion control and laser drilling systems that serves semiconductor, electronics and industrial customers. The strategic logic is breadth. Few competitors span flow, pressure, power, reactive gas, lasers, optics and chemistry, and the 10-K itself says no single competitor competes across all product lines. The financial reality is that breadth was bought with debt. Goodwill and intangibles were USD 4.7 billion, or 54% of total assets, at the end of 2025. ### Revenue model | Revenue type (USD M) | FY2023 | FY2024 | FY2025 | |---|---|---|---| | Products | 3200 | 3124 | 3436 | | Services | 422 | 462 | 495 | | Total net revenues | 3622 | 3586 | 3931 | | Services share of revenue (%) | 11.7 | 12.9 | 12.6 | **Products:** FY2023: 3200; FY2024: 3124; FY2025: 3436 **Services:** FY2023: 422; FY2024: 462; FY2025: 495 **Total net revenues:** FY2023: 3622; FY2024: 3586; FY2025: 3931 **Services share of revenue (%):** FY2023: 11.7; FY2024: 12.9; FY2025: 12.6 Source: FY2025 10-K. MKS has no subscription or licensing line of any scale. Products were 87.4% of FY2025 revenue and services 12.6%. Management's own measure is wider: consumables and service together were 39% of Q2 2026 revenue (Q2 2026 results presentation), and this recurring share is one of the main differences between MKS and pure subsystem peers. Services carry the higher gross margin, at 52.5% in FY2025 against 45.9% for products (computed from the FY2025 10-K). ### Value chain position MKS sits between component suppliers and two customer groups. Upstream, it buys electronic, optical and mechanical components and chemical feedstocks, some under sole-source or "copy exact" arrangements. Downstream, it sells to: - semiconductor capital equipment manufacturers, whose tools specify MKS subsystems for product lifespans that have historically run five to fifteen years - semiconductor device manufacturers, who buy service, repair and spares and can direct equipment makers to use MKS products - PCB and package substrate manufacturers, who buy chemistry, plating lines and laser drilling systems - specialty industrial customers across automotive surface finishing, life and health sciences, research and defense ### Customers and concentration MKS sells to thousands of customers. The top ten represented 35%, 32% and 30% of net revenues in 2025, 2024 and 2023, and no customer exceeded 10% in those years (FY2025 10-K). This is a major change from the pre-Atotech company, when Lam Research and Applied Materials together were 24% to 27% of revenue in 2020 to 2022 (earlier 10-Ks). ### End markets | End market revenue (USD M) | FY2021 | FY2022 | FY2023 | FY2024 | FY2025 | |---|---|---|---|---|---| | Semiconductor | 1825 | 2041 | 1479 | 1498 | 1696 | | Electronics and Packaging | 344 | 541 | 916 | 922 | 1111 | | Specialty Industrial | 780 | 964 | 1227 | 1166 | 1124 | **Semiconductor:** FY2021: 1825; FY2022: 2041; FY2023: 1479; FY2024: 1498; FY2025: 1696 **Electronics and Packaging:** FY2021: 344; FY2022: 541; FY2023: 916; FY2024: 922; FY2025: 1111 **Specialty Industrial:** FY2021: 780; FY2022: 964; FY2023: 1227; FY2024: 1166; FY2025: 1124 Source: annual results releases and FY2025 10-K. **Semiconductor:** (43% of FY2025 revenue) covers deposition, etching, cleaning, lithography, metrology and inspection. **Electronics and Packaging:** (28%) covers photonics components, laser drilling systems, electronics chemistries and plating equipment for PCBs, package substrates and wafer-level packaging, plus vacuum and photonics solutions for display. **Specialty Industrial:** (29%) covers functional coatings and surface finishing, synthetic diamond, solar and LED manufacturing, bioimaging and medical applications, and research and defense.
