% of holdings sold = shares sold ÷ (shares sold + all holdings the insider reported on that Form 4, direct and through trusts).
Insider type follows Cohen, Malloy & Pomorski (Journal of Finance, 2012). An insider who traded the stock in the same calendar month in each of the past three years is a routine trader; one who traded in each of those years without such a pattern is an opportunistic trader. In their study, trades by opportunistic insiders predicted future returns and trades by routine insiders did not. Counts open-market purchases and sales only (SEC Form 4 codes P and S) by that insider in that company. Not investment advice.

From MKS Inc.'s Latest SEC 10-K Filing (filed 2026-02-24)
Key Strengths & Strategy (as disclosed to the SEC)
- We rely on a combination of patent, copyright, trademark and trade secret laws and license agreements to establish and protect our proprietary rights.
- We require each of our employees, including our executive officers, to enter into standard agreements pursuant to which the employee agrees to keep confidential our proprietary information and to assign to us all inventions while they are employed by us.
- We have developed the following two product strategies that have been instrumental in delivering value to our customers and helping them solve their most complex problems: Our Surround the Wafer® offering includes a wide range of products, design and development services, system-level integration, training programs, calibration, service, and repair for our semiconductor customers.
- In our chemistry and equipment plating businesses, a majority of our research and development investment supports existing customers' product improvement needs and their short-term research and development goals, which enables us to pioneer new high-value solutions while limiting commercial risk.
Partnerships
- Leveraging these themes and data points, tailored action items were created to encourage meaningful change, with corporate initiatives focusing on innovation and cross-departmental collaboration.
Legal & Regulatory Risks (Item 1A, quoted)
- Increased restrictions on China have led to and may continue to lead to regulatory retaliation by the Chinese government and further escalate geopolitical tensions between China and Taiwan.
- We are subject to international trade compliance regulations, and violations of those regulations could result in fines or trade restrictions, which could have a material adverse effect on us.
- Changes in tax rates or tax regulation or the termination of tax incentives could affect our operating results.
- Changes in U.S. tax law, such as the One Big Beautiful Bill Act, and changes in regulations and tax guidance may affect our business. Additionally, the United States is considering various corporate and international income tax proposals, which, if enacted, could have a material impact on our provision for income taxes and effective tax rate.
