MKS Inc: what insiders have been doing
MKS Inc is a Technology company. Its directors and officers file their transactions with SEC (Form 4). 17 insiders have disclosed 46 filings since 18 October 2025.
The flow runs one way only: 25 sales worth €16.7M, from 12 insiders, and no purchase. At €2.9M, the sale published on 23 February 2026 by Lee John Tseng-Chung is the largest of the period.
Across the 5,458 companies tracked on its exchange, the median is 22 filings; at 46 filings, this issuer sits above that mark. Our records for MKS Inc go back to 2016, with 3 purchases and 80 sales on the open market in total. For the fiscal year to 31 December 2025, the annual 10-K puts revenue at 3.93 bn USD and net income at 295.0 m USD, and the dividend at 0.88 USD per share.
Typically, a trade is published a median of 1 day after it takes place. Section 16 rules allow two business days to file each Form 4. Keep in mind that insiders sell for many reasons unrelated to the outlook, from tax bills to estate planning.

About MKS Inc
MKS Inc. is a US-based technology company headquartered in Andover, Massachusetts, in the United States, and listed on the NASDAQ (NYSE/NASDAQ: NASDAQ). Founded in 1961, the company has evolved from a measurement-and-control specialist into a diversified provider of enabling technologies for advanced manufacturing. Today, MKS serves three primary end markets: semiconductor manufacturing, electronics and packaging, and specialty industrial applications. Its business model is centered on highly engineered solutions that are embedded in customers’ critical production processes, which gives the company a strong technical moat and a recurring need for customer support, calibration, integration, and lifecycle services.
MKS’ product and solution portfolio is broad. It includes pressure and flow measurement and control, gas and vapor delivery, gas composition analysis, power generation and delivery, vacuum technology, lasers, photonics, optics, precision motion control, vibration control, and laser-based manufacturing systems. The company also offers process chemicals and specialty electroplating solutions through Atotech, which is part of its Materials Solutions division. In practical terms, MKS sells instruments, subsystems, systems, and associated services that improve process performance, productivity, yield, and reliability in complex manufacturing environments.

From a competitive standpoint, MKS is a niche industrial technology leader rather than a high-volume commodity supplier. Its position is particularly strong in semiconductor wafer fabrication, advanced packaging, photonics, and precision industrial applications where process control and repeatability are mission-critical. A key strategic concept is its “Surround the Workpiece” approach, which aims to deliver end-to-end solutions across product design, system integration, process control, maintenance, and calibration. This integrated offering deepens customer relationships and raises switching costs, especially in industries where manufacturing precision directly affects output quality and economics.
Recent developments reinforce MKS’ exposure to structural growth themes. In 2025 and 2026, the company highlighted new photonics solutions tied to AI, quantum, biophotonics, and advanced manufacturing at Photonics West in San Francisco. It also advanced its industrial footprint, including a new chemical manufacturing and TechCenter facility in Thailand to support Southeast Asia’s PCB and advanced packaging ecosystem. On the capital structure side, MKS announced refinancing initiatives in 2026 that extended maturities and improved financing flexibility, while management also pointed to growth opportunities tied to AI-driven data center demand and advanced packaging. For investors, MKS stands out as a technically differentiated US-listed NASDAQ name with exposure to long-term semiconductor and photonics growth, balanced by the cyclical nature of its end markets.
