Insights

Equity analyst

MKS posts stronger 2025 earnings and de-risks its balance sheet.

MKS Inc. delivered higher full-year 2025 revenue of $3,931 million and GAAP net income of $295 million, with Non-GAAP diluted EPS at $7.88. Growth was driven mainly by semiconductor and electronics and packaging net revenues, while margins remained in the mid-teens on a GAAP basis and low-20s on a Non-GAAP basis.

The company generated robust operating cash flow of $645 million in 2025 and free cash flow of $497 million, supporting both investment and debt reduction. It prepaid $100 million on its USD term loan B in Q4 and later issued €1.0 billion of 4.25% senior notes due 2034, using proceeds and refinancings to prepay approximately $1.3 billion of prior USD term loan B and fully refinance its EUR term loan B.

These actions reduced interest expense versus 2024, extended maturities and diversified funding, while the revolving credit facility was increased to $1 billion. For Q1 2026, guidance implies relatively stable revenue around $1,040 million at a gross margin near 46.0%, with Non-GAAP diluted EPS centered at $2.00. Overall, the combination of earnings growth, strong cash generation and proactive refinancing appears favorable for financial flexibility.

Use of Non-GAAP Financial Results

This press release includes financial measures that are not in accordance with U.S. generally accepted accounting principles (“Non-GAAP financial measures”). These Non-GAAP financial measures should be viewed in addition to, and not as a substitute for, MKS’ reported results under U.S. generally accepted accounting principles (“GAAP”), and may be different from Non-GAAP financial measures used by other companies. In addition, these Non-GAAP financial measures are not based on any comprehensive set of accounting rules or principles. MKS management believes the presentation of these Non-GAAP financial measures is useful to investors for comparing prior periods and analyzing ongoing business trends and operating results.

MKS is not providing a quantitative reconciliation of forward-looking Non-GAAP net earnings, Non-GAAP net earnings per diluted share, Non-GAAP operating expenses, and Adjusted EBITDA to their most directly comparable GAAP financial measures because it is unable to estimate with reasonable certainty the ultimate timing or amount of certain significant items without unreasonable efforts. These items include, but are not limited to, fees and expenses related to amendments to the Term Loan Facility and Revolving Credit Facility, amortization of debt issuance costs, interest expense, and the income tax effect of these items. These items are uncertain, depend on various factors, including, but not limited to, our recently completed private offering of €1.0 billion principal amount of 4.25% senior notes and refinancing of our Term Loan Facility and Revolving Credit Facility on February 4, 2026, and could have a material impact on GAAP reported results for the relevant period.

For further information regarding these Non-GAAP financial measures, please refer to the tables presenting reconciliations of our Non-GAAP results to our GAAP results and the “Notes on Our Non-GAAP Financial Information” at the end of this press release.
