MKS Inc.
MKS Inc. is a registered legal entity registered in United States, and its current status with Massachusetts Secretary of the Commonwealth is active. Its registered address on file is Andover, United States. 5 shareholders are on record for MKS Inc., and since every one of them is a company rather than an individual, this particular filing does not on its own establish an ultimate beneficial owner (UBO) — identifying one would mean tracing the ownership of each shareholding company in turn. This profile is sourced directly from Massachusetts Secretary of the Commonwealth and was last updated on 29 September 2026.

Shareholders
5
Five shareholders are currently on record for MKS Inc., reflecting the stock ledger maintained under state corporate law (e.g. §219 of the Delaware General Corporation Law) rather than a public filing.
The largest of these is Invesco Ltd., holding 4.3% — the largest recorded stake — followed by Neuberger Berman Group, LLC at 3%; the remaining 3 shareholders shown hold smaller stakes.
The register reports 20 shareholders in total, though only the top 5 by holding are shown in this view.
Because every shareholder shown is a company rather than an individual, the ownership chain continues above this level, and no beneficial owner can be established from this filing alone.
| Shareholder | Type | Holding | Source Document |
|---|---|---|---|
| Invesco Ltd. | 4.3% | Massachusetts Secretary of the Commonwealth | |
| Neuberger Berman Group, LLC | 3% | Massachusetts Secretary of the Commonwealth | |
| Fidelity Puritan Trust-Fidelity Low-Priced Stock Fund | 2% | Massachusetts Secretary of the Commonwealth | |

Officers
5
The Evp & Cfo of MKS Inc. currently on record is Ramakumar MAYAMPURATH; five officers are currently on record for MKS Inc., filed with Massachusetts Secretary of the Commonwealth.
The register reports 10 officers in total, including past appointments, though only the 5 most relevant records are shown here.
Management authority at MKS Inc. sits with these individuals, not with shareholders, who are covered separately and hold ownership rather than control.
The source filing doesn't specify representation authority — whether officers can act individually or must sign jointly to bind the company — so that detail isn't available here.
Group Structure
MKS Inc. has no recorded parent company — it sits at the top of its own group structure, with 22 subsidiaries recorded beneath it across 7 jurisdictions. Each of these downward relationships is derived rather than filed: resolved by matching entities across the registry network, not stated directly in a single document.
Those 22 subsidiaries span United States, Canada, Malaysia, Argentina, Thailand, Romania, and 1 more jurisdictions, though this list should not be read as complete — subsidiaries only become visible here where shareholder data has actually been filed with a register, so holdings in jurisdictions without that filing simply won't appear. Three of the 22 go a level deeper still, with their own further subsidiaries recorded beneath them — additional ownership layers this view doesn't expand.
