Routine 8-K furnishing of earnings release; administrative in nature.

MKS Inc. announced quarterly results for the period ended September 30, 2025 via an attached press release (Exhibit 99.1). The company used Item 2.02, which typically accompanies earnings disclosures.

The company states the information is furnished, not filed, under the Exchange Act, which limits Section 18 liability and standard incorporation by reference. This is a common approach for earnings releases.
